Abstract Introduction: More than 90% of children infected with COVID-19 worldwide developed mild to moderate disease. In Colombia, during 2020, COVID-19 infections in children stayed below 9.2% of the total cases, with no trends for age group or sex. Objective: To estimate the incidence of acute respiratory symptoms and COVID-19 in children from public schools in Bogotá, Colombia during the second semester of 2020. Material and methods: A telephone survey was conducted in over 5,000 scholar children. Antecedents and use of health services were informed. Descriptive statistics were used. Results: A total of 151.470 persons per day accounting for an IR of 157,8 per 100,000 people; almost three times the rate reported by the official surveillance system in the city. Conclusion: A lack of diagnosis and consultation in children was found compared to the general population. Further research is needed to elucidate the true burden of the disease in children.


AbstractDiffusion welding of titanium cylinders to an alumina cylinder (Ti/Al2O3/Ti) was carried out at temperatures above the α–β transition temperature of titanium. Titanium and alumina were welded under the following conditions: maximum heating temperature greater than 1400 K, holding time of 30 s, heating (cooling) rate of 1–10 K s−1, welding pressure of 1·6 MPa, and an air atmosphere. The shear strength of Ti/Al2O3/Ti welds was very low because of the residual stress at the welded interface. Alumina cylinders were welded using titanium foil as an insert (AI2O3/Ti foil/Al2O3). The shear strength of Al2O3/Ti foil/Al2O3 welds increased slightly with the decrease of foil thickness, and attained a maximum value of 82 MN m−2. When the foil thickness was less than 10 μm, the welds failed at the welded interface, but the welds with foil of 100 μm thickness failed in alumina close to the interface.MST/1114


This paper shows the behavior of several dielectric properties of corona-resistant polyimide tapes as a function of thermal (high temperatures) and ambient stress (high humidity coupled with high temperature). The main goal of the investigation is to understand and explain the evolution of the partial discharge endurance of the tapes as a function of nonelectrical aging. The results indicate that polyimide tapes are very stable up to temperatures of 320°C. However, the most elevated temperatures reduce the partial discharge endurance to 50% of the original value. This is probably due to morphological changes in the (outer) nanostructured layers of the tapes.


The unexplained inaction on the part of the Reagan Administration to complete a policy for regulating genetic engineering products may be pushing Congress to pass legislation to fill the void. A joint hearing of two House subcommittees this month highlighted the frustration and confusion surrounding biotechnology for both government and industry. The purpose of the hearing was to air views on H.R. 4452, the Biotechnology Science Coordination Act of 1986, introduced by House Committee on Science & Technology chairman Don Fuqua (D.-Fla.). The bill focuses on developing a consistent approach to regulating biotechnology products in which useful applications of genetic engineering can be developed while protecting human health and the environment. Although that is the goal of the Administration, the results so far have not demonstrated that consistent approach. For example, tests of a swine vaccine made of a genetically altered live virus were approved, but proper procedures were not followed in granting that ...


Those of us who have particle identification problems sometimes have very small samples, say, only a few nanograms - even less sometimes. We also like to make up permanent Aroclor 5442 preparations of these tiny samples for safe keeping and future reference. If we mount such small samples in a normal drop of Aroclor filling an 18 mm diameter coverslip, we may spend a few frustrating minutes looking for the sample in a few acres of Aroclor. My solution is to use a very tiny Arocior droplet under a small coverslip. Ten millimeter or smaller round coverslips are available from Erie Scientific in Portsmouth, New Hampshire.


In a bid to optimize the performance of a Pelton Wheel Turbine developed the performance evaluation of the turbine at various conditions was carried out using a portion of the overflow from the University of Ilorin (UNILORIN) dam. The collected overflow has a net head of 4 m, flow rate of 0.017m3/sec. and theoretical hydropower energy of 668W. The turbine was tested and the optimized value of operating conditions namely; angle of inclination (15o above tangent, tangential and 15o below tangent), height to impact point (200 mm, 250 mm and 300 mm) and length to impact point (50 mm, 100 mm and 150 mm) were pre-set at their various levels. The measured outputs were Turbine Speed, Turbine Torque, Alternator Speed as well as the output voltage. The optimum values of the process output or measured parameters were determined statistically using a 33X2 factorial experiment in three replicates. The optimum Turbine speed (538.38 rpm) in off load condition was achieved at 250 mm height to impact point, 150 mm length to impact point and angle at tangential inclination. Similar combination also yielded an optimum turbine torque of 46.16 kNm. The optimum Turbine speed (392.02 rpm) in on-load condition was achieved at 250 mm height to impact point, 150 mm length to impact point and angle at tangential inclination. Similar combination also yielded an optimum Turbine Torque of 36.46kNm, optimum Alternator speed of 1768.56 rpm and an optimum output voltage of 7.87V. The results therefore show that the turbine must be set at 250 mm height to impact point, 150 mm length to impact point and the water jet at a tangential flow for it to perform optimally.


In this paper, we examine the benefits of split-TCP proxies, d ployed in an operational world-wide cloud service network, for acc elerating web search queries. We consider a fraction of a network consisting of la rge number of satellite data centers, which host split-TCP proxies, and a small er number of large data centers, which compute real time responses to search querie s. Detailed measurements reveal that a vanilla TCP splitting solution deployed at the satellite data centers reduces the 95 percentile of latency by as much as 40%, as compared to serving queries directly from the large data centers. Throu gh careful dissection of the measurements, we identify three areas, where optimizat ions significantly further improve performance: 1) adopting FEC-based low latenc y reliable protocols between proxies and data centers; 2) choosing proxies based on network latency; 3) specific customizations of TCP for short transfers.


Congenital chest wall or pectus deformities including pectus excavatum (funnel chest) and pectus carinatum (pigeon chest) affect a significant proportion of the general population and up to 70% of patients with Marfan syndrome. Patients often experience significant morbidity and psychological distress, which can worsen with age. Here we discuss new techniques for both operative and non-operative treatment of pectus deformity, the importance of a welltimed intervention and special considerations in patients with Marfan syndrome.


The numerous problems of the traditional security technologies have led to a rise in developing biometric systems. Many traditional biometric systems, such as fingerprint, face, and iris systems have been studied extensively in the previous decades .Nowadays the concept of using the dorsal vein pattern in authentication that uses the vast network blood vessels underneath a person's skin showed to be a proven biometric technique. Different trails have been done to extract veins patterns and build systems that can give good performance. In this paper, we proposed an automatic system for human identification based on their dorsal vein patterns. Within this approach preprocessing steps are implemented to get the enhanced grayscale images with visible and clear veins. Two features extraction techniques are used, Principle Component Analysis (PCA) and Scale Invariant Feature Transform (SIFT), to get eigenveins and keypoints respectively. Statistical distance classifiers are implemented for classification. Finally the results from both classifiers are fused using simple min rule. The system has been successfully tested on a database of 100 users using MATLAB version 2009. The obtained results show that the proposed system outperforms the results of each individual system (PCA, SIFT).


The general theoretical model predicts the amount of threshold voltage change with time for both writing and storage modes of operation. Experimental data fit these theoretical expressions containing no adjustable parameter.


The Sawayaerdun gold deposit in Wuqia County of southwest Xinjiang occurs in Upper Silurian and Lower Devonian epimetamorphic carbonaceous turbidite, with the host rocks being carbonaceous phyllites, metasandstone and metasiltstone. Gold mineralized zones and orebodies are controlled by the brittle-ductile shear zone. Fluid inclusions in the Sawayaerdun gold deposit can be divided into two-phase vapor-liquid H_2O inclusions, liquid-rich H_2O inclusions, vapor-rich H_2O inclusions, daughter mineral-bearing polyphase inclusions and three-phase CO_2-type inclusions, of which two-phase vapor-liquid H_2O inclusions seem to be the main type. The ore-forming fluids are of the middle-low temperature (78~355℃) and low-middle salinity 〔2.57%~22.10% (w(NaCl_(eq)))〕 H_2O-NaCl-CO_2-CH_4 system. The δ~(34)S values of sulfides associated with gold mineralization range from -3.0‰ to +2.61‰ with a mean of 0.07‰, indicating that sulfur was derived from the mantle or the mantle-related magma. The δ~(13)C_(PDB) values of dolomite and siderite from the Sawayaerdun gold deposit range from -5.4‰ to -0.6‰, suggesting that carbon mainly came from the mantle and marine carbonate rocks. Hydrogen and oxygen isotope studies show that the ore-forming fluids were mainly derived from meteoric water, with a minor part from magmatic fluids. The Sawayaerdun gold deposit resembles the Muruntau gold deposit in Uzbekistan and the Kumtor gold deposit in Kyrgyzstan in geological setting, metallogenic characteristics and ore-forming mechanism. Nevertheless, the Sawayaerdun gold deposit shows some particularities: the ore-forming process is characterized by epizonal mineralization, and the association of medium-low temperature elements such as gold and antimony makes up the most prominent feature. Changes in physico-chemical conditions of ore fluids and fluid compositions, water-rock exchange and immiscibility of ore fluids played important roles in the ore-forming process of the Sawayaerdun gold deposit.


It has been said, "Censorship is the bastard child of technology." Technological advances in video gaming software have created a rapid evolution from 1970's arcade game technology to today's role playing games, featuring an almost life-like level of realism, which mirrors the natural world in all of its graphic violence and sexual activity. In tandem with electronic gaming's rapid evolution and realism has been a meteoric rise in popularity and revenues which now rivals that of the motion picture industry. This tremendous growth and change has also spurred protest from family values groups. The fact that violence, sex, and videogames seem to play well in the media has brought out a fair number of lawmakers, eager to prove their "family values" mettle by answering the call that something be done at the legislative level to control access by minors to this increasingly violent and sexually-explicit game content.


This article addresses psychic representation and its relation with language on Freud's initial studies. It presents an overview of Freudian theory of implicit representation in the monograph on aphasias and discusses the understanding of these concepts under a contemporary perspective of language. It defends that, since its beginning, the theory of psychic representation goes beyond the language structure because this is secondary to the investigation of the meaning of unconscious production and drives. The conclusion is that addressing the psychic representation under the perspective of language is necessary but insuffi cient for the study of the freudian metapsychology.

The shell be made of the resin by injection molding; moreover, different paints or noctilucence materials can be added in the resin, so that the color of the shell can be diversified, and the shell can present in different shapes.


In the present invention, audio information is transmitted from a transmission node as packets (P1, P2, ..., Pm) of which the data volumes (q1, q2, ..., qm) have the relationship q1 < q2 < ... < qm. A reception node selects one packet on the basis of the lag times (t1, t2, ..., tm) of the packets (P1, P2, ..., Pm).


The literature dedicated to the study of Argentine commercial policy during the period 1870-1913 has alternately established it as liberal, protectionist or fiscalist. In this research, we propose to study it mainly from the customs laws - although we also use other dispositions, resolutions and decrees related to the subject. Our hypothesis is that the Argentine trade policy cannot easily be categorized, because it showed both signs of liberalization and protectionism, and fiscal intentions. In effect, sectors with interests, sometimes similar and sometimes dissimilar, influenced the evolution of trade policy. This paper has been divided into four parts. It begins by presenting which the tax-free exports and imports were. It then goes on to observe which products paid export and import duties, what was the weight of customs duties on state revenues, what the average tariff levels were, and what the difference between nominal protection and implicit protection was. In the next section, we present what elements should be studied in order to reach a complete analysis of the commercial policy, which includes the reconstruction of the effective tariffs of the period, both for exports and for imports. Finally, we make a balance (still provisional) based on the main findings of this research.


This article describes the main themes, funding needs, and policy options of the Working Group on the Environment in US-China Relations that was created in November 1996. Meetings are chaired by members of the Council of Foreign Relations and the Carnegie Endowment for International Peace. The 40+ member Working Group is coordinated by the Environmental Change and Security Project and the Woodrow Wilson Center's Asia Program. It offers a forum for discussion of environmental and foreign policy concerns. The aims are to identify important environmental and sustainable development issues related to US and Chinese interests; to develop creative strategies for government and nongovernment projects between the US and China; and to discuss strategies for using environmental issues for building improved relations between countries. Monthly meetings focus on energy issues, water quantity and quality, funds for environmental protection, and biodiversity issues. The group meetings emphasize the themes of multilateral cooperation, local Chinese environmental issues of significance to the US, and obstacles to cooperation on US-led projects within China. Improved relations may be achieved by articulation of a coherent China policy with explicit goals and guidelines, provision of funding, and linking local environmental problems with global ones. The US should support private business in marketing environmental technology and assist in the development of policy changes in the energy and water sectors in China. China needs improved irrigation techniques and comprehensive watershed management plans.


In general, the necessary requirements for implementing a network management system are considered as network management protocols, object-oriented information modeling, management functions/services, and a graphical user interface (GUI) in a distributed environment. Java/sup TM/ is designed to meet the challenges of application development in the context of heterogeneous, network-wide distributed environments and provides the capabilities of simplicity, object-oriented concept, reliability, portability, multi-threading, and viewer capability. Thus, it is proper to make the development environment using Java for network management system. Especially, the "translation of GDMO/ASN.1 to Java objects" mechanism is designed and implemented for the information model of the TMN. It is used as a core facility to produce the Java objects which represent managed objects.


The purpose of this study was to examine the relationship between birth order, vocational choice, choice of college, and selected personality characteristics among Black college students. The 16 Personality Factors Question naire, the Assessment of Career Decision Making, and a research questionnaire were administered to a sample of 231 students enrolled in freshman orientation classes at Grambling State University, Grambling, Louisiana. Analysis of variance revealed no significant differences among the birth order groups. It was concluded that the validity of birth order theory for Black college students should be questioned.


The relaxation processes of photoexcited carriers in GaAs/AlAs multiple quantum well structures grown at low temperatures by molecular beam epitaxy were studied by a tunable single-beam femtosecond pump–probe method. Concentrations of singularly ionized antisite arsenic ions, AsGa+, in the quantum wells, which were considered as traps of photoexcited carriers, were estimated from flux conditions and substrate temperatures in the growth. Transient transmittivity of the structures were measured by varying the pump–probe photon energy. The trapping rate of photoexcited carriers, which corresponded to the reciprocal of the carrier lifetime, was derived from the relaxation profile at the pump–probe photon energy close to the exciton resonant excitation energy for each structure. The trapping rate was found to increase linearly with AsGa+ in a lower concentration range and superlinearly in a higher concentration range. Photoluminescence and absorption spectra were observed at room temperature and their correlat...

The aim of the work is to form the principles of a personalized approach to the management of patients with COVID-19 with a complicated comorbid background. Material and methods. The article describes a clinical case of successful recovery of an 87-year-old patient from a new coronavirus infection COVID-19, complicated by pneumonia involving 36% of the lung parenchyma area. Along with age, the situation was aggravated by the comorbid status of the patient: the presence of chronic lymphocytic leukemia, hypertension, mechanical prostheses of the mitral and aortic valves, postinfarction cardiosclerosis, paroxysmal atrial fibrillation, type 2 diabetes mellitus, stage 4 CKD, anemic syndrome, and subclinical hypothyroidism. Results. The C-reactive protein level at admission was 114.46 mg/L. The patient refused hospitalization. Baricitinib 4 mg, favipiravir according to the scheme, vitamin D 2000 units were prescribed for the previously taken therapy. Already after 3 days, C-reactive protein decreased by 4.6 times, and by the 8th day by 15.5 times and amounted to 7.38 mg/ml. The temperature returned to normal on day 2 from the start of baricitinib. In dynamics, a decrease in creatinine level to 177.0 mumol/l was noted, the glomerular filtration rate increased to 30 ml/min/1.73 m2, which corresponded to stage 3b of CKD (a pronounced decrease in glomerular filtration rate). Conclusion. Despite the age of the patient, many comorbidities, each of which could be fatal, the timely use of baricitinib on an outpatient basis made it possible to stop the progressive course of the disease.Copyright © Eco-Vector, 2023.

Endophytic fungi are important components of plant micro-ecosystems and they exist usually inside the healthy tissues of living plants. Endophytes possess encouraging source of biologically active metabolites for pharmaceutical applications. This study isolated endophytic fungi from Pteridium acquilinium and Newbouldia laevis leaves and evaluated their antioxidant and antibacterial activities. A total of ten endophytic fungal species were isolated from the leaves of the plants, from which six were selected and identified, including; Epicoccum thailandicum; Trichoderma atroviride; Lasiodiplodia parva; Trichoderma yunnanense; Colletotrichum cobbittiense; and, Trichoderma crissum. Among the isolated fungi, Trichoderma crissum (266.2956 ± 84.84 µg/ml) and Lasiodiplodia parva (293.0755 ± 64.95 µg/ml) showed significant scavenging activity on comparison with ascorbic acid. Furthermore, the isolated endophytes showed potential antibacterial activity against the tested clinical pathogens. This study validates that endophytic fungi dwelling in the inner tissue of medicinal plants studied could be a potential source of biologically active metabolites with free radical scavenging activities and also for treatment of infectious diseases caused by Staphylococcus aureus, Pseudomonas aeroginosa and Escherichia coli.


This paper examines Italo Calvino's Invisible Cities as a unique literary canvas to reformulate the relationship between narratives and planning practices. It does so from the vantage point of the Frame, namely, the dialogues between the Khan (the planner) and Marco Polo (the resident/traveler) punctuating the imaginary cities described in the book. Read through with the aid of narratological concepts, the Frame functions a mini-treatise on urban complexity, structured along nine dyads of oppositional concepts (e.g., chaos vs. meaning; reality vs. possibility), which call into question as many planning milestones (e.g., control, purpose, model, balance), fostering an original reflection on the limitations and potentials of planning practices.


This study investigated Jordanian pre-service teachers' beliefs about the learning and teaching of mathematics. One aim of the study was to identify possible explanations for why Jordanian students score much lower than many of their global counterparts on international mathematics tests. On the 2007 Trends in International Mathematics and Science Study (TIMSS), Jordanian eighth-graders' average score was 427, far below the TIMSS scale average of 500. Jordan ranked 31st out of the 48 participating countries. On the 2011 TIMSS, Jordanian eighth-graders' average dropped to 406, and Jordan's overall ranking was 49th out of 56 participating countries and education systems. In addition to investigating Jordanian pre-service teachers' beliefs, the findings were compared to the findings from a similar study in South Korea (Kim, 2009), the top performing country in mathematics in 2011 and second overall in 2007 on the TIMSS assessments. The participants in this study were 441 pre-service teachers enrolled in 5 universities in Jordan, four public and one private. Participants' data were collected using a questionnaire survey, the same instrument that was used in the Korean study of 2009.


The prevailing of malware variants in ubiquitous Internet of Things (IoT) devices causes enormous losses. Accurate and timely identification of malware variant traffic at an IoT edge gateway can effectively reduce the loss. TransNet, the state-of-the-art technology for malware variant traffic detection, considers only global domain adaptation and ignores the alignment of distributions between different subdomains, which fails to capture the fine-grained information of classification targets. Besides, TransNet converges very slowly, which may use up precious resources in IoT devices. This article proposes a deep subdomain adaptation network with attention mechanism (DSAN-AT) to accurately and efficiently identify malware variant traffic at an IoT edge gateway. DSAN-AT utilizes local maximum mean discrepancy (LMMD) to align the traffic feature distributions of subdomains in the source and target domains. It also exploits channel and spatial attention mechanisms to accelerate learning traffic features between different subdomains to save precious computing resources at the IoT edge gateway. Our experimental study demonstrates that DSAN-AT achieves an average accuracy of 97.15% (96.37% for TransNet) and converges fast without using a large target domain training data set. DSAN-AT has strong practicality for identifying malware variant traffic at an edge IoT gateway.


Addresses can be classified as unstructured text because they lack meta-information to be directly indexed in databases. Still they demonstrate an internal structure which can used to automatically extract them using machine learning techniques. In this work we describe a machine learning approach to identify addresses in unstructured text (like blogs) using Bidirectional Recurrent Neural Networks (BRNNs). We overcome the problem of lack of training data by generating synthetic free text entries and come up with problem specific features. Our system does not impose any strict condition on the structure or style of addresses leading to many applications in real life.


A comparative study of photoluminescence (PL) quenching of shallow bound excitons (BE's) associated with shallow donors and acceptors and of deep isoelectronic bound excitons (IBE's) in Si in a weak electric field at liquid-He temperatures is reported. In both cases the photoluminescence is quenched due to impact ionization by field-accelerated hot carriers. A comparison between n- and p-type samples showed no significant difference in quenching rate for the shallow donor- and acceptor-related BE's; the quenching starts around 50 V/cm, and both electrons and holes are released as free carriers in the impact process. The IBE's show a completely different behavior and a different impact mechanism. IBE's first show an increase in PL intensity with applied electric field and are difficult to completely quench before the electrical breakdown of the sample around 400 V/cm. In this case it is concluded that only one carrier is released from the center in the impact process. By impact ionizing the shallow donor- and acceptor-related BE's and the free excitons, an efficient recombination channel for free carriers is removed, and the carrier lifetime is drastically increased. This opens up new recombination channels, such as free-to-bound transitions, which are not seen in the absence of an electric field.


The main objective of this thesis is to determine a credit risk model that could be used to value
credit default swaps (CDSs). A literature study identifies that structural models are able to meet this objective and that they could also be used for analysis on default probabilities and recovery rates. Two structural models are selected for further research. In the first model the firm's assets value process is a jump-diffusion process and default is modeled as the first-passage of a constant
default barrier. The second model uses the same jump-diffusion process for the firm value, but incorporates a mean reverting leverage process to model default. We implement both models in Matlab using (Brownian Bridge) Monte Carlo simulations to analyze the sensitivity of modeled CDS term structures to value changes in the input parameters. We find that both models can calculate non-zero short-term CDS spreads and that the second model generates upward sloping term structures over a long time horizon. From three cases studies in which we compare modeled CDS spreads to the market spreads of Dutch firms we find that an advanced parameter estimation methodology is necessary to provide consistent jump and diffusion parameter values throughout the economic cycle.


Identifying parallel sides of a collection of Euclidean polygons yields a flat surface with cone points of angles multiples of 2 pi, naturally a compact Riemann surface but also an algebraic curve, and a hyperbolic surface. In general two different metrics on a surface have no geodesic arcs in common, but in special cases the surface is decomposed into polygons geodesic for both the flat and the hyperbolic metric. This is the case for certain surfaces which are translation and half-turn tiled by an Euclidean rectangle. We explore them in this paper. Their multi-geodesic tessellation provides a mechanical way to reconstruct a Fuchsian group for them; allows to describe their Teichmueller disk in terms of Fenchel-Nielsen coordinates; allows for an interpretation in terms of fractional Dehn twists of the natural PSL_2(Z) action on the PSL_2(R)-orbit of such surfaces. In many cases the tiling by rectangles allows to recover an equation for the corresponding algebraic curve, providing a bridge between the algebraic equation and the hyperbolic structure deduced from the multi-geodesic tessellation; in other words solving the uniformization problem for such curves. In fact it also gives a scheme to do uniformization for infinitely many families of curves. We also discuss some number theoretic aspects.


The Yakutsk array dataset in the energy interval $(10^{17},10^{19})$ eV is revisited in order to interpret the zenith angle distribution of an extensive air shower event rate of ultra-high energy cosmic rays. The close relation of the distribution to the attenuation of the main measurable parameter of showers, $S_{600}$, is examined. Measured and expected distributions are used to analyze the arrival directions of cosmic rays on an equatorial map including the energy range below $10^{18}$ eV, which was previously avoided due to the reduced trigger efficiency of the array in the range. While the null hypothesis cannot be rejected with data from the Yakutsk array, an upper limit on the fraction of cosmic rays from a separable source in the uniform background is derived as a function of declination and energy.

We study optimal portfolio, consumption‐leisure and retirement choice of an infinitely lived economic agent whose instantaneous preference is characterized by a constant elasticity of substitution (CES) function of consumption and leisure. We integrate in one model the optimal consumption‐leisure‐work choice, the optimal portfolio selection, and the optimal stopping problem in which the agent chooses her retirement time. The economic agent derives utility from both consumption and leisure, and is able to adjust her supply of labor flexibly above a certain minimum work‐hour, and also has a retirement option. We solve the problem analytically by considering a variational inequality arising from the dual functions of the optimal stopping problem. The optimal retirement time is characterized as the first time when her wealth exceeds a certain critical level. We provide the critical wealth level for retirement and characterize the optimal consumption‐leisure and portfolio policies before and after retirement in closed forms. We also derive properties of the optimal policies. In particular, we show that consumption in general jumps around retirement.


Definition 1. Let D = {x ∈ R||x| < 1} be the open n-dimensional disc and D+ := [0, 1)×Dn−1 the half-disc. By an n-manifold we will mean a (not necessarily compact) Hausdorff second countable space M which is locally homeomorphic at every point x ∈ M to either D or D+. The boundary ∂M ⊆ M is the subspace containing those points with local neighborhoods D+. We will say that M is open if ∂M = ∅. A map ι : N −→ M between n-manifolds is said to be an open embedding if it is injective and sends open subsets to open subsets. Note if ι : N −→ M is an open embedding then ι−1(∂M) = ∂N . The set Emb(M,N) of all open embeddings can topologized using the compact-open topology. We will denote by Mfld∂n the ∞-category whose objects are the n-manifolds and whose mapping spaces are the spaces of open embeddings. We will denote by Mfldn ⊆Mfld∂n the full subcategory spanned by the open n-manifolds. We recall from the previous talk that both these ∞-categories carry natural symmetric monoidal structures, which are given each time by disjoint union. Let Top(n) be the topological group of self homeomorphisms of D. The natural map Top(n) −→ MapMfldn(D ,D) induces a map BTop(n) −→ Mfldn, where BTop(n) is the classifying ∞-groupoid of Top(n). Consider the composed functor (1) Mfldn −→ Fun(Mfld n ,Spaces) −→ Fun(BTop(n),Spaces) ' Spaces/BTop where the first functor is the Yoneda embedding. Given an open n-manifold M ∈ Mfld we will denote by p : |M | −→ BTop(n) the image of M under (1). We will refer to |M | as the underlying space of M , and the Top(n) bundle classified


The National Center for Health Statistics is integrating three hospital surveys into one survey named the National Hospital Care Survey. The new survey will measure the provision and utilization of medical care services provided by non-Federal, noninstitutional hospitals with six or more inpatient beds and by freestanding ambulatory surgery centers in the United States. Similar to the prior surveys, data will be collected in national samples of hospital discharges, ambulatory surgeries, and visits to hospital emergency and outpatient departments. Relative to the prior surveys, the new survey covers an expanded hospital population and targets additional estimates. This paper discusses the sampling design for the new survey and selected differences between the old and new survey designs.


Abstract. Thermophotovoltaic (TPV) systems are promising for harnessing solar energy, waste heat, and heat from radioisotope decay or fuel combustion. TPV systems work by heating an emitter that emits light that is converted to electricity. One of the key challenges is designing an emitter that not only preferentially emits light in certain wavelength ranges but also simultaneously satisfies other engineering constraints. To elucidate these engineering constraints, we first provide an overview of the state of the art, by classifying emitters into three categories based on whether they have been used in prototype system demonstrations, fabricated and measured, or simulated. We then present a systematic approach for assessing emitters. This consists of five metrics: optical performance, ability to scale to large areas, stability at high temperatures, ability to integrate into the system, and cost. Using these metrics, we evaluate and discuss the reported results of emitters used in system demonstrations. Although there are many emitters with good optical performance, more studies on their practical attributes are required, especially for those that are not yet used in prototype systems. This framework can serve as a guide for the development of emitters for long-lasting, high-performance TPV systems.


In the 1990s workers in Australia were increasingly subjected to negative work pressures. Irregular work patterns, work intensification, and the transformation of the notion of career, often in the name of 'flexibility', were increasingly common. This period was also characterised by scant regard for the quality of working life of young people in entry-level employment, which is often portrayed as a transition stage prior to their admission into the full-time core workforce. This paper explores the experiences of twenty-two young people at the beginning of their careers, in the hospitality and retail industries, with reference to three quality of working life (QWL) elements: hours flexibility, work-life balance and career potential. Qualitative evidence reveals a variety of experiences but, on balance, suggests a negative quality of working life and limited commitment to their current industry. In conclusion, the paper suggests that these industries must pay more attention to QWL issues in order to attract and retain quality staff.


We consider the optical properties of the solar gravitational lens (SGL) treating the Sun as a massive compact body. Using our previously developed wave-optical treatment of the SGL, we convolve it with a thin-lens representing an optical telescope, and estimate the power spectral density and associated photon flux at individual pixel locations on the image sensor at the focal plane of the telescope. We also consider the solar corona, which is the dominant noise source when imaging faint objects with the SGL. We evaluate the signal-to-noise ratio at individual pixels as a function of wavelength. To block out the solar light, we contrast the use of a conventional internal coronagraph with a Lyot-stop to an external occulter (i.e., starshade). An external occulter, not being a subject to the diffraction limit of the observing telescope, makes it possible to use small telescopes (e.g., ∼ 40 cm) for spatially and spectrally resolved imaging with the SGL in a broad range of wavelengths from optical to mid-infrared (IR) and without the substantial loss of optical throughput that is characteristic to internal devices. Mid-IR observations are especially interesting as planets are self-luminous at these wavelengths, producing a strong signal, while there is significantly less noise from the solar corona. This part of the spectrum contains numerous features of interest for exobiology and biosignature detection. We develop tools that may be used to estimate instrument requirements and devise optimal observing strategies to use the SGL for high-resolution, spectrally resolved imaging, ultimately improving our ability to confirm and study the presence of life on a distant world.


expected to change physiological processes in plants, it is becoming increasingly important to monitor the changes in plant traits and subsequent phenological changes that may occur. Changes in photosynthetic pigments, such as chlorophyll, can be used as a proxy for physiological changes in leaves and can therefore be useful to monitor potential phenological change, such as autumnal leaf senescence. Non-destructive techniques allow for measurements of photosynthetic pigments without destructive sampling that would disturb the canopy. These methods are particularly useful in logistically difficult environments, such as high forest, or remote environments where traditional chlorophyll extractions are problematic and serve as groundtruthing for remote sensing of greenness. In the present study, we aimed to assess the effects of elevated CO 2 (150 mmol mol -1 above ambient) and canopy position on chlorophyll concentrations of a common canopy-dominant species to identify potential implications on phenology. The study was conducted in a mature temperate forest situated at a Free Air Carbon Enrichment (FACE) experiment in the UK. Over 5,000 in-situ chlorophyll measurements were collected, across the 3 rd


In this paper we obtain exact solutions of the general- ized Kuramoto-Sivashinsky equation, which describes many phys- ical processes in motion of turbulence and other unstable process systems. The methods used to determine the exact solutions of the underlying equation are the Lie group analysis and the simplest equation method. The solutions obtained are then plotted.


Tocqueville's concept of the "tyranny of the majority" can benefit social justice pedagogies owing to its capacity to illuminate the silent, invisible character of hegemonic power. As many critical pedagogues have pointed out, this silent and invisible power seeps not only into the public spaces of education, but also into the private spaces of students' identities—as well as our own—shaping both what is discussed and what tends to go un-discussed within American classrooms. This essay explores the pedagogical potential of Tocqueville's concept of the tyranny of the majority—that is, how it can be theorized in ways that enable us to critically understand the "anti-democratic" silences and civic self-conceptions of majority privilege.


Autoantibodies to human corneal epithelium were demonstrated by the immunofluorescent technique in the serum of a patient suffering from ulcus rodens corneae (Mooren's ulcer). These antibodies were demonstrated in serum obtained before lamellar keratoplasty, and in samples taken 1½ and 4 years, respectively, after operation, when the process had reached the terminal stage. No antibodies fixed in vivo were demonstrated in the patient's own corneal tissue using the direct immunofluorescent technique.

However, in the serum of three other patients suffering from the same disease no antibodies could be demonstrated. Two of these sera were from patients who had undergone keratoplasty.


In this paper a new system for creating spatial semantic documentation is shown. We define semantic documentation as a result of integrating semantic mapping with a mobile 3D geodetic scanning system and a cloud computer system. This approach is possible by using semantic mapping State of the Art [2], modern scanning techniques [3] and parallel computing [4]. The main task of the system is representing the environment with concepts of objects highlighted in it. The results are distributed in a cloud. The phases of system operation are shown in Fig. 1.

Rice is the major source of food for more than half of the world population. Rice suffers from many biotic and abiotic factors which results in the lower productivity. Blast disease is considered as major threat to rice cultivation. Thus, 7 fungicides, 4 bio agent and 7 plant extracts were evaluated. Among fungicides tested, all the fungicides found effective but Carbendazim and Propiconazole showed inhibition of 84.07 per cent and 74.25 per cent respectively at 500 ppm. Among the bio-agents tested, Trichoderma viride showed maximum inhibition with 64.44 per cent followed by Trichoderma harzianum with inhibition of 59.04 per cent, the least inhibition was recorded in Bacillus subtilis with inhibition of 47.48 per cent. The extracts of Lantana camara (55.80%), Neem (53.06%) and Nilgiri (51.83%) were showed maximum inhibition of pathogen at higher concentration.

About 80% shipwreck occurred by human error, human error is 75% due to the poor management system, it must be made to the management system that is able to create a good and close cooperation between the management board and land management. International Safety Management Code (ISM Code) is an international standard of safety management regulations for the security and safety of the operation of the ship and the prevention of pollution of the marine environment established by the IMO Maritime Safety Council. Purpose ISM Code is to ensure safety at sea, prevent accidents and loss of human life and avoid damage to the environment, especially the marine environment and as well as the loss of property. Companies must certify in writing its policy on maritime safety and environmental protection and ensure that everyone in the company know and understand it. But perception Crew and Application Management in the ISM Code For Maritime Safety and Marine Environment Protection can be different if there is no good training and application of the management company. To that periodically companies need to conduct training on the prevention and prevention of disorders of the safety of shipping activities concerned Shipping Company. To overcome and prevent safety, Shipping Company should have the facilities and equipment in accordance with the provisions of the ISM Code.

The article deals with the problems that confront modern society owing to globalization in culture and interpersonal communication. The digital revolution in the modern world causes great changes, not only in various spheres of human activities, but also in the domain of spirit, and society has to meet new cultural imperatives. In this context, the author writes about civilizational shifts that demand greater than ever consistency between economics, politics and culture. The notion of innovation does not only belong to the economic field, as innovative activity also affects human mentality. Social relationships become a field of warfare through exchange of information and opinions. The author is guided by philosophical-anthropological approaches to interpretation of human nature and, following Bergson's philosophy, she makes a distinction between intellect and spirit, which is significant for pedagogy. Knowledge should be accompanied by enhancement of the creative and spiritual potential. Thus, the interests of the digital industry (increasing the number of users by facilitating work techniques, by attractive games and entertainment, improving performance, and creating the effect of emotional release) do not coincide with the interests of either social culture or ethics of public life (expanding intellectual cooperation, building mutual understanding, developing collective intelligence, promoting access to education and demand for new knowledge). The concept of human rights, which initially assumed the supremacy of universal values in every person, cannot be reduced to the ethics of comfort. The author concludes that it is only through personal development that human beings can solve actual problems of their existence.


Sparse recovery space-time adaptive processing (SR-STAP) can achieve an ideal clutter suppression with very few training samples, however, its application faces two challenges: 1) severe gird mismatch effect and 2) large time-resources requirement. In practice, a coarse space-time grids will bring a serious mismatch between the true clutter points and the divided grids, which leads to a significant performance degradation of clutter suppression. Although the high-resolution mesh can effectively reduce the grid mismatch effect, its cost is huge computational load. Thus, it is meaningful to reduce the large-scale dictionary operation complexity while maintaining suboptimal clutter suppression performance for SR-STAP when applying in real airborne radar system. This article proposed a tensor-based SR-STAP scheme aims at large-scale dictionary application. In the proposed framework, traditional vector-based operations are replaced by their corresponding low-complexity tensor representation. As a result, a large-scale matrix operation can be degraded into multiple small-scale matrix calculation, thus the huge computational loading can be saved in recovery. A comparison of tensor-based SR-STAP and traditional vector-based SR-STAP in large-scale dictionary application is also exhaustive discussed here. Based on this framework, a tensor-based sparse Bayesian learning and its fast matrix-realization form are developed. A series of carefully designed numerical simulation and measurement experiments indicate that the significant advantages of the tensor-based SR-STAP whether in performance or computation loading.


ABSTRACT Graft-polymerization of acrylic acid (AAc) monomer onto poly(tetraflouroethylene-perflouro vinyl ether) (PFA) copolymer film was carried out using gamma irradiation technique to synthesize grafted copolymer film PFA-g-PAAc (PFA-COOH). The effect of the dose on the degree of grafting of AAc onto PFA film was investigated. The results showed that the degree of grafting increases with increasing the irradiation dose. The grafted [PFA-COOH] film was chemically modified by reaction with aniline to produce modified [PFA-CO-NH-ph] film, followed by sulphonation reaction to introduce sulfonic acid (SO3H) groups to get other modified [PFA-CO-NH-ph-SO3H] film. The chemical structures of the grafted and modified films were identified by FT-IR, XRD, and SEM. It is of particular interest to measure the electrical conductivity of grafted and modified membranes as a function of degree of grafting. It was found that the conductivity of the grafted films increases with increasing the degree of grafting, however a slightly increase in conductivity was observed in [PFA-CO-NH-ph-SO3H] sample. The electrical conductivity property of the modified PFA membranes suggests their possible use for fuel cell applications.

Conclusion: Most clinical trials research results show that PG has its unique advantages compared with pancreticojejunostomy (PJ), especially in the prevention of postoperative pancreatic fistula pancreaticoduodenectomy. PG's safety, easy operation, and other advantages have been recognized by more and more clinical doctors.


This paper contests the view that, before the U.S. tariff increases of 2018 and 2019, governments around the world successfully resisted protectionist pressures since the onset of the global financial crisis. Before President Trump was inaugurated, the cumulative build-up of over 11,000 policy interventions that discriminated against foreign commercial interests implicated over two-thirds of world goods trade. An exploratory data analysis of possible drivers of national policy mixes towards domestic and foreign commercial interests is presented. Clear differences between G20 and other nations and between the immediate crisis response (from November 2008 to December 2010) and afterwards are found.


Anchihaline coastal caves have been studied from various points of view. Hydrogeological studies have dealt with the saturation index of calcite, aragonite and dolomite as functions of salinity (HERMAN et al. 1985, SMART et al. 1988). Zoological studies describe srygobiontic species of several groups, and biogeographical studies have also been made (STOCK 1981, SKET 1994). The latest monograph dealing with them (C~MACHO 1992) included ecological studies, but physico-chemical changes, meromixis and the food web were not included. Only PALMER (1986) has described profiles of conducrivity and temperature in relation to aquatic species. Comments on photosynthetic meromictic lagoons in the Iberian Peninsula can be found in MIRACLE et al. (1992). Many coastal caves occur in calcareous deposits of rhe Balearic Islands, some very near rhe coastline, where there are brackish pools of different salinity and oxygen concentration, among other variables recorded.


This article posits that among the many different methods being used to try to increase enforcement of Western style IP laws in China, that ultimately one of the most effective methods may be to support and aide the slow but steady shift in Chinese culture, away from a collective society view, and towards an individual ownership view – not reasons not based purely on economics, but also as a benefit from a cultural and social perspective – with broader support for the concept of individual rights and freedoms on a variety of fronts, and not just the IP arena. In this context also, I note in passing that the movement in China to embrace many of the attributes of Western culture is a mixed blessing, as media coverage of the rise in obesity and lung cancer in China is an example of a byproduct of some of the less salutary aspects of Western culture. 1 The merit of this hypothesis is shown in this article by the discussion of the specific example of calligraphy arts, and the more general example of modern art creation and marketing in China. The teaching and marketing of modern art, and of modern calligraphy as an art form, provides a demonstration of my hypothesis. Calligraphy symbols in China are, in essence, pictograms that draw their inspiration from things found in nature – trees, rocks, animals, elements, etc. For most of the history of calligraphy as an art form in China, this source history supported the view that calligraphy symbols could not, and should not, be • Marc H.

News, last viewed at http://news.yahoo.com/s/afp/20080708/hl_afp/chinaushealthobesityresearchp_ylt. protected by copyright – just as in patent law, you cannot obtain a patent on items found in nature. However, modern calligraphy art, uses the symbols of traditional calligraphy only as a jumping-off point – the modern works contain interpretations of these classic symbols that are virtually unrecognizable, and are imbued deeply with the artist's own vision and perspective – they often bear no visible resemblance to their source symbols at all. Since these symbols, under a Western view, would, by virtue of their age and utilitarian function, be deemed to be in the public domain, the new calligraphy artists would face no derivative rights challenges, and would be entitled to claim sole ownership of these works. The first section of this Article looks at modern art in China. Two key trends emerge, each of which has different impact on the recognition and enforcement of copyright law in China. The first trend is the copy art industry – the use of assembly line techniques to produce cheap, popular artworks, often copies of traditional and contemporary art, including popular works of European and American artists. The second trend is the unexpected recognition of a burgeoning contemporary art scene in China, and how its leading artists have become "rock stars" in their country and beyond, with their work bringing multi-million dollar sales and allowing them to enjoy newfound individual wealth and status, contrary to longstanding tradition for Chinese artists. The second section looks at the history of copyright, first in a summary fashion as to Western European and U.S. law, and in more detail as to China. Copyright law in China is traced from its Imperial age origins, followed by a consideration of how copyright has been implemented during modern times in both the communist nation of the People's Republic of China on the mainland, and the Republic of China (ROC) on the island of Taiwan. The third section of this Article discusses why, despite efforts by both the Chinese government, and Western governmental entities, the attempt to import Westernstyle copyright enforcement mechanisms have been largely unsuccessful to date. This section explores the need for approaches other than those rooted in the law, suggesting that changes in social norms and the migration of China into a "socialist market economy" may hold the answer to the problem of developing a cultural shift in favor of the kind of private ownership approach that best supports a vigorous copyright protection system. The final section explores how Chinese Calligraphy, a classic and highly traditional art form in China, which eschewed the concept of individual ownership, has, through the operation of these three approaches, in law, economics and normative social expressions, evolved into a very different contemporary form of artistic expression, marked by individual expression and ownership, and offers this evolution as a basis for suggesting that as this and other forms of fine art evolve in China, they present an opportunity to convert those artists into the kind of stakeholders, to borrow the concept articulated by Professors Peter Yu and William P. Alford in many of their published works, which may provide the best opportunity to create an environment more conducive to successful enforcement of copyright protection for members of the Chinese creative community.


It is shown, by using the trace formula of Selberg type, that every primitive, one-dimensional homology class of a negatively curved compact locally symmetric space contains infinitely many prime closed geodesics. 0. Let M be a compact space form of a symmetric space of rank one. In this note, we prove that each homology class in H1 (M, Z) contains infinitely many free homotopy classes of closed curves, that is, the mapping induced from the Hurewicz homomorphism [XI (M)] -? H1 (M, Z) is an oo-to-one correspondence. One of the geometric consequences is that any primitive homology class contains infinitely many prime closed geodesics, since, as was shown by Hadamard, every nonnull homotopy class contains a closed geodesic which is automatically prime if the homology class is primitive. Here a homology class a is called primitive if Ol is not a nontrivial integral multiple of another homology class. If dimM = 2, then one can prove the much stronger assertion that every homology class contains infinitely many prime closed geodesics (see ?2). The following theorem, which can be shown by means of a number-theoretic argument applied to the L-functions associated to length spectrum of closed geodesics (see [1, 4] for proof), is somewhat related to the result. THEOREM. Let H be a subgroup of H1(M, Z) of finite index, and let al be a coset in Hi/H. If M is negatively curved, then there exist infinitely many prime closed geodesics whose homology classes are in ca. 1. The proof relies heavily on the trace formula for the heat kernel function. We shall start with a general setting. Let 7r: M -? M be the universal covering of a compact Riemannian manifold M. The fundamental group ri (M) acts on M in the usual way. For brevity we write r for 7ri(M). For an element -y in r, we denote by rF the centralizer of -y, and by [-y] the conjugacy class of -y. The set of all conjugacy classes is denoted by [r]. Let p: r -, U(N) be a unitary representation, and let Ep be the flat vector bundle associated to p. We denote by AP the Laplacian acting on the sections of Ep. The fundamental solution of the heat equation on M will be denoted by k(t; x, y). The following lemma is proved in the same way as the proof of the Selberg trace formula (see [6]).

A sustainable development requirement consists in the conservation and enhancement of agricultural resources, monitoring the economic development impact upon the environment, in order to ensure the support for future generations. The essential role in agricultural production is played by the rational use of natural resources. In this context, one of the most important challenges in ensuring food security for the population is represented by the increase of food production under the back- ground of soil degradation. The evaluation of the conceptual framework of natural capital protection reveals the acceleration of soil degradation, this becoming an extremely pressing cross-border problem. At European level, Romania is one of the countries with a generous endowment in natural agricultural resources. In spite of this, our country is confronted with specific problems, i.e. a defective management of land resources, resulting in an accelerated soil degradation rate. The indicators regarding soil degradation and agricultural land quality classes can contribute to the explanation of low land productivity, together with other factors. The land use modality reveals that there is always a compromise between different social, economic and environmental needs (e.g. dwellings, transport infrastructure, energy production, agriculture, nature protection). The current trends in land occupation have a non-sustainable character, representing one of the important causes of soil degradation.


Rotational shot-put technique is superior to backfacing sliding shot-put technique in terms of bio-dynamics.However,only few Chinese male shot athletes have adopted this technique presently.A feasibility study on the adoption of this technique is conducted and its teaching methods,difficult and key points are analyzed.


The Saint‐Venant theory proposes an exact solution to the elastic equations for beams including warping strains due to shear force and torsion. It has been at the centre of recent developments in the field of beam theory: normal stress may at first be determined as if plane sections would remain plane but under torsion and shear force, restrain warping introduces secondary normal stress.


The competition that exists among the higher education institutions involves great efforts to adapt to the new requirements of the modern society. The educational offers must face the new challenges that require flexibility, rapidity, complexity and provide students both with specific habits and efficient work tools. Our research aimed at identifying the perception of students from the Faculty of Economics and Business Administration (FEAA), which belongs to "Alexandru Ioan Cuza" University of Iasi, concerning the utility and degree of acceptance of the new e-learning methods. We try to analyze the degree of opposition in adopting them, the limits and motivations, the preference for a certain type of teaching-learning (usual, e-learning, mixed), as well as at finding out the way in which students perceive the assessment of their knowledge by using the new information technologies. The research demonstrates that there are significant differences between what is required and what is expected on a theoretical level from the new educational systems as well as the way in which they are accepted and used by students in practice. The main identified barrier is the students' reluctance towards the new learning methods due, in our opinion, to the human opposition to change on the one hand and on the other hand to the lack of information about its advantages. We consider appropriate expanding research topic article to the other universities in the country in order to understand the impact of current e-learning as a whole, at national level.


Abstract Let p be a prime. We say that a transitive action of a group L on a set Ω is p-sub-regular if there exist x,y∈Ω such that 〈Lx,Ly〉=L and LYx≅ℤp, where Y =yLx is the orbit of y under Lx. Our main result is that if Γ is a G-arc-transitive graph and the permutation group induced by the action of Gv on Γ(v) is p-sub-regular, then the order of a G-arc-stabilizer is equal to ps−1 where s≤7, s≠6, and moreover, if p=2, then s≤5. This generalizes a classical result of Tutte on cubic arc-transitive graphs as well as some more recent results. We also give a characterization of p-sub-regular actions in terms of arc-regular actions on digraphs and discuss some interesting examples of small degree.


The capital asset pricing model (CAPM) is often based on the Gaussianity or normality assumption. However, such an assumption is frequently violated in practical situations. In this paper, we introduce the symmetric CAPM considering distributions with lighter or heavier tails than the normal distribution. These distributions are symmetric and belong to the family of elliptical distributions. We pay special attention to the family members related to the normal, power-exponential, and Student-t cases, with the power-exponential distribution being particularly considered, as it has not been explored widely. Based on these cases, the expectation-maximization algorithm can be used to facilitate the estimation of model parameters utilizing the maximum likelihood method. In addition, we derive the leverage and local influence methods to carry out diagnostics in the symmetric CAPM. We conduct a detailed case study to apply the obtained results estimating the systematic risk of the financial assets of a Chilean company with real data. We employ the Akaike information criterion to conclude that the studied models provide better results than the CAPM under Gaussianity.


During 2019 –2020, we selected 75 samples of potatoes, carrots, turnips, cabbage, onions, both in the field and from storage. Bacteria of the genus Pectobacterium were isolated from 60 samples. Strains of Bacillus pumilus, Bacillus sp. and Pseudomonas sp. were also isolated. The dominant species causing soft rot and black leg of potato were Pectobacterium carotovorum, P. parmentieri, P. atrosepticum and P. brasiliense. Bacterium P. carotovorum was isolated from other vegetable crops. In samples of carrots and potatoes, strains of bacteria of the genus Bacillus were often isolated from storage. For the first time in Belarus, we found the bacterium P. brasiliense on potato plants. The results obtained on the identification and spread of soft rot bacteria in Belarus will help plan the risks associated with infections caused by these pathogens.


In order to improve the application of shape memory polymers in extreme harsh environments, the ultrathin carbon fibers reinforced polyether-ether-ketone (CF/PEEK) composite with 0.036 mm thickness was fabricated by overlapping and hot-pressing technologies, and the shape memory behaviors of the composite under the action of thermal stress were investigated. The results show the shape recovery rate of CF/PEEK composite ultrathin laminate is approximately 100%, and still has above 90% reversion rate after 100 times tests of thermal cycling action at 320℃. The stress-driving deformation mechanism of CF/PEEK composite is explained based on the relationship between temperature and stress-strain. The CF/PEEK composites with variable thickness were designed to simulate the deformation and recovery of complex shapes, containing deep-sea coral, cube and pitcher plant. Using mechanical clamping force during the deformation of CF/PEEK composite, the grasping coin experiment was carried out, which verifies the application feasibility for the active deformed structure of CF/PEEK composite.


Circular arrays are an appealing if underused option for radar systems that require 360° coverage in azimuth. They require no mechanical scanning and do not suffer from the high-angle scan loss and beam broadening of linear and planar arrays. The circular geometry, along with suitable pattern synthesis techniques, enables some unique capabilities. On transmit they provide the flexibilty to synthesize a continuum of beam shapes, from omnidirectional to sector to high gain. On receive, simultaneous high-gain beams can be formed to cover any desired azimuth footprint. In this paper we explore the capabilities of circular arrays through a series of pattern synthesis design examples.


Raper 1 and his associates, in a comprehensive study of the tyrosine-tyrosinase reaction, showed that the enzyme tyrosinase obtained from plant sources catalyzes the conversion of tyrosine to dopa (3,4-dihydroxyphenyl-l-alanine). Dopa is then oxidized, in the presence of the same enzyme, to a red indole derivative, which changes spontaneously to melanin. Melanin formation in mammals has remained somewhat of an enigma, despite the demonstration by Bloch 2 of an intracellular oxidase which catalyzes the oxidation of dopa to melanin but is without apparent effect on tyrosine. The presence of dopa in mammalian tissue or fluids has never been demonstrated, and it has not been known how tyrosine is converted into dopa. Recently, however, the enzymatic formation of melanin from tyrosine has been conclusively demonstrated in several types of mammalian tissue, including beef ciliary bodies 3 and human, 4 horse 5 and mouse 6 melanomas. The enzyme has been shown to


An embodiment of the present invention provides a multi-user cooperative communication method, a network element on a core network side, and a network element on a radio access network side. The method comprises: the network element on the radio access network side monitoring supporting information which is the information provided by a Supporting User Equipment (S-UE) for communication of a Benefitted User Equipment (B-UE), the communication being assisted by the S-UE; and, after a certain condition is satisfied, the network element on the radio access network side transmitting the supporting information to the network element on the core network side, so that the network element on the core network side converts the supporting information into a reward to the S-UE. The network element on the radio access network side monitors and performs statistics of the supporting information provided by each UE as the S-UE for assisting the communication of the B-UE, and transmits the supporting information to the network element on the core network side, the network element having a function of billing, and the network element on the core network side converts the supporting information into the reward to the S-UE, and therefore the UE acts as the S-UE and a larger scope of the multiple user cooperative communication is realized.


The documented results form part of a larger research program to study the mechanical and environmental properties of asphaltic mixtures containing incinerator bottom ash aggregate (IBAA). The fracture characteristics of four mixtures containing 0%, 30%, 60%, and 80% IBAA by weight were investigated under monotonic and cyclic semi-circular bending conditions. The linear elastic fracture mechanics (LEFM) approach was used to evaluate crack resistance of the tested mixtures with the aim of investigating the effect of IBAA content on these properties. LEFM led to the determination of the stress intensity factor, the J-integral, fracture energy, and Paris law parameters. Crack propagation was monitored with a digital camera, and a program developed in-house was adopted in interpreting crack growth. In addition, a new approach was presented to obtain asphalt fatigue damage parameters from fracture tests. Results showed a benefit to be gained in adding IBAA up to a certain amount, beyond which cracking properties become close to those of the control mix.


In order to understand the development of traditional Chinese medicine(TCM),this paper analyzed the attitudes of health care providers in the sample districts from 2000 to 2008. It was found that the belief of health care providers on TCM had been weakened,and TCM was regarded as a simple supplement to western medicine. In this case,grasping TCM characteristics and innovating and promoting new treatments were particularly important to increase the support and recognition of health care providers on TCM.


Background : As a component of the nation's progress, the development of the child must be considered. Nutrition of children should be monitored because nutrition is to be a prerequisite in academic performance of children, such as consumption of energy food and habits of breakfast. Several studies have reported that children who do not eat breakfast have lower concentrations than children which often eat in the morning. Children who eat rich of energy showed an increase in creativity, physical endurance, and value as compared to children who consume low energy. Objective : To know the difference of academic performance some subjects based on energy intake and breakfast frequency of elementary school in SD N Unggaran 1 Yogyakarta. Methods : This researchwas conducted as across-sectionalresearch at 78 students in SD Negeri Ungaran 1 Yogyakarta. We choosed students who met the inclusion criteria using a simple random sampling. We analyzed for bivariate analysis with fisher�s exact test. Result : Out of 78 students, there were 73% students have good energy intake, 27% have low energy intake and 59% have habitual to eat breakfast (� 4 times / week), 41% are not habitual to eat breakfast ( 0,05) and there is no difference between academic performance some subjects based on frequency of breakfast (p>0,05). Conclusion : There is no difference between academic performance some subjects based on energy intake and frequency of breakfast


. The present paper investigates the response of masonry structural elements with periodic texture adopting an advanced multiscale finite element model, coupling different formulations at the two selected scales of analysis. At the macroscopic structural level, a homogeneous thick shell is considered and its constitutive response is derived by the detailed analysis of the masonry repetitive Unit Cell (UC), analyzed at the microlevel in the framework of the three-dimensional (3D) Cauchy continuum. The UC is formed by the assembly of elastic bricks and nonlinear mortar joints, modeled as zero-thickness interfaces. The Transformation Field Analysis procedure is invoked to address the nonlinear homogenization problem of the regular masonry. The performance of the model in reproducing various masonry textures is explored by referring to an experimentally tested pointed vault under different profiles of prescribed differential settlements. The structural behavior of the vault is studied in terms of global load-displacement curves and damaging patterns and the numerical results are compared with those recovered by detailed micromechanical analyses and experimental evidences.

Objective:To study the effects of n-butanol extracts from Portulaca oleracea on the learning and memory performances of senile mice induced by D-gal and its mechanisms. Method:The mice were randomly divided into 3 groups:control group,model group and the n-butanol extracts(0.5 g/(kg·d) and 0.25 g/(kg·d) ) groups. The control group was given hypodermic injection of isotonic NaCl in the transverse part while the other groups successively administered with D-gal(1 g/(kg·d) ) . After injection of medicine in the afternoon of every day model animals were obtained after 42 d of treatment. Learning and memory performances were measured by step-through test and water maze test and the amount of MDA in mouse brain tissue and the activities of SOD and GSH-Px were determined. Results:Portulaca oleracea n-butanol extracts could improve the learning and memory performances of mice at both 0.5 g/(kg·d) and 0.25 g/(kg·d) ,and substantially reduce contents of MDA in brain tissues and improve activities of SOD and GSH-Px. Conclusion:Portulaca oleracea n-butanol extracts can markedly improve learning and memory performances of senile mice. The mechanisms of effects may be related to the improvement of SOD and GSH-Px activities and the decrease of MDA.


Abstract The nonsphericity parameter γrelated to the Isihara shape factor for ovaloid polymers f by the relation f = (γ/4) + (1/4) is calculated through an expansion of the radius of the molecule in spherical harmonics. The limitations of the method when applied to polymers with high f are discussed.


Since the relatively recent advent of evaluation research, researchers have overwhelmingly advocated the use of experimental designs over other methodological approaches. However, implementing such designs produces an interaction effect which greatly alters the nature of programs being evaluated. As an alternative to experimental designs, an interactionist approach to evaluation research is introduced and developed, both conceptually and procedurally. The advantages of a phenomenological skepticism, which is epistemologically integral to an interactionist approach, over an experimentalist's naive or common sense skepticism, is discussed. Stages and methodological problems of carrying out an interactionist approach are explicated.

It is argued that the implementation of an interactionist approach would be "nonreactive" with either the structure or functioning of a program under analysis. And it would simultaneously bring into relief much of the anxiety and distrust between researchers and those being evaluated that characteristically accompanies the application of experimental designs.


A study of the emission of high-energy electrons from the surface of polymer films being peeled from lithium fluoride single crystals has revealed that the emission intensity increases with increasing concentrations of dislocations in the surface layer of the single crystal (provided that the dislocations are introduced into a single crystal already forming an adhesive bond with a polymer film).


The purpose of this research is to predict the performance of 2000 meters indoor rowing using 100-meter test, 60s test and 6000-meter test. The sample used is 22 rowing athletes, consisting of 10 male lightweight athletes, 3 male heavy weight athletes, 7 female light weight athletes and 2 female heavyweight athletes aged around 19 ± 29 years old, who joined the Program Indonesia Emas. Participants give written approval before participating in this research. All experimental procedures are approved by the Executive Board of the Indonesian Rowing and Canoeing Association (PB PODSI). The test was performed with a physical test series developed by Danish Rowing, taking a standard of 21 Danish rowers. Rowing athletes participate in a series of physical tests conducted within 4 days, displaying all out performance for specified test types as well as the distance specified using Concept2, type C rowing ergometer. The results of this study is a prediction of 2000 meter power performance based on 100 meter test power performance, 60 second test and 6000 meter test. This study reflects an optimal physiological adaptation for rower performance. Rowers can use the same general training preparations, whether they are open classes or light classes, male or female. Dividing the training according to the endurance curve for each rower. If an oarsman does anaerobic tests poorly, he may have to do more strength training and power exercises. On the other hand, if an oarsman is too strong in relation to his aerobic endurance, he should focus on aerobic training. This research will be useful, because the trainer will get the profile data of each group or athletes that will be a reference for trainers in sorting out and choosing what physiological aspects should be a priority target in planning the exercises.

This paper describe briefly how the Ad hoc On-demand Distance Vector (AODV) routing protocol can be used for internetworking between wireless ad hoc networks and the IPv6 Internet. This solution relies on the signalling of AODV to find an access providing Internet Gateway that is able to distribute a globally routable prefix for the ad hoc network. We have tried to evaluate this solution by means of simulation in order to stress the design and find areas that need improvement. We have observed that a critical factor in this design is how to determine whether the node is located in the ad hoc network, or located on the Internet. In addition to these design considerations we have also investigated common performance metrics such as end-to-end delay, delivery ratio and routing overhead and verified that these are not affected in a negative way by the design.


Abstract : During 1980, we completed the proposed studies of collisional redistribution in the thallium-argon system. The work included experimental and theoretical studies of both spontaneous and stimulated light scattering by atoms in a collisional environment. The principal work included studying the effects of radiative trapping on the shape of the spontaneous redistribution line profile, and developing and applying a theoretical model to the data previously obtained on stimulated Raman scattering (SRS) and stimulated collision-induced fluorescence (SCF).


Stroke neuroprotection trials suggest that pharmacological manipulations of a single neuroprotective mechanism are generally ineffective and that new approaches, possibly involving simultaneous manipulations of multiple mechanisms, need to be sought. To identify optimal components for such a multipronged approach, we studied NMDA receptor activation‐induced cell death in organotypic hippocampal culture preparations as a model of excitotoxicity. Metabotropic group I glutamate receptor (mGluR) activation by their selective agonist, (S)‐3,5‐dihydroxyphenylglycine (DHPG), resulted in concentration‐dependent reduction of nerve cell susceptibility to NMDA‐mediated injury (neuroprotective effect). The neuroprotection was mediated primarily by mGluR1, required phospholipase C activation, was inhibited by cholesterol‐containing methyl‐β‐cyclodextrin treatment, and occluded by antipsychotic quetiapine. It was associated with suppression of NMDA currents and prolongation of GABAA receptor‐mediated currents in DHPG‐treated cultures. cDNA microarray analysis of 1128 brain‐relevant genes revealed that mGluR‐mediated neuroprotection was associated with simultaneous activation of endocytosis, and inactivation of inflammation, cell adhesion, cell death, and transcription‐related genes. Antisense inhibition of Rab5b, a gene coding for a small GTPase associated with endocytosis, significantly reduced the mGluR‐mediated neuroprotection. These findings expand our understanding of the role that mGluRs play in regulation of nerve cell susceptibility to injury and should facilitate the design of novel therapeutic strategies for stroke and other neurodegenerative diseases.


In fluid mechanics, drag related problems aim to reduce fuel consumption. This paper is intended to provide guidance for drag reduction applications on cars. The review covers papers from the beginning of 2000 to April 2020 related to drag reduction research for ground vehicles. Research papers were collected from the library of Science Direct, Web of Science, and Multidisciplinary Digital Publishing Institute (MDPI). Achieved drag reductions of each research paper was collected and evaluated. The assessed research papers attained their results by wind tunnel measurements or calculating validated numerical models. The study mainly focuses on hatchback and notchback shaped ground vehicle drag reduction methods, such as active and passive systems. Quantitative analysis was made for the drag reduction methods where relative and absolute drag changes were used for evaluations.

Abstract Introduction A lean six-sigma (LSS) approach to clinical redesign looks at aspects of patient flow, value to consumer and any areas that may be considered wasted time. This LSS approach was used to find areas of improvement in a tertiary care hospital for patients on non-invasive ventilation. The solution developed was to implement a remote download service. Methods Root cause analysis, current state process and effects analysis, staff surveys and time and motion work sampling studies were conducted. There was a post implementation time and motion work sampling study for the remote download service introduced in 2023. Results Motion, transportation, inventory and waiting time and reporting software were found to impact workflow. Time efficiencies were found for non-invasive ventilation download reports with a mean time of 14.8 mins (std 6.7min) pre-implementation down to 2.5 mins (std 0.6min) with remote software. There was an additional time saving due to batch processing prior to clinics of 2.5 mins (std 0.4mins) per patient. Staff reported workload capacity and documentation as two key barriers to effective processes. Discussion LSS identified areas to improve value and flow for staff in sleep clinics and patients on non-invasive ventilation.


PROBLEM TO BE SOLVED: To provide a construction method for a marine structure capable of improving productivity and workability. SOLUTION: A construction method for a pier 1 includes: an arrangement step in which a plurality of permanent forms 13 are arranged in the area excluding a beam forming area R on a base plate 11 of a precast panel 10; and an installation step in which concrete is placed on the beam forming area R that appears between the plurality of permanent forms 13 arranged on the base plate 11 and on the plurality of permanent forms 13 themselves, which comprises a beam 6 and a slab 7 joined to a plurality of pile heads 2a. In this way, a superstructure 3 having the beam 6 and the slab 7 is formed by preparing the plurality of permanent forms 13 and the precast panel 10, by arranging the plurality of permanent forms 13 on the base plate 11 of the precast panel 10, and by placing concrete on the base plate 11, which prevents from making and assembling a burial mould in a complex shape and improves productivity and workability.

Main goal is to work out the conception of development of food manufacturing in general in the region and in the districts and farms.


This article investigates whether the Aspect-before-Tense Hypothesis (Antinucci and Miller, 1976; Shirai and Andersen, 1995) accounts for the acquisition of tense-aspect morphology in child L2 English. The main question addressed is whether early uses of tense-aspect inflections can be analyzed as a spell-out of semantic/aspectual features of verbs (such as punctuality, telicity, durativity, etc.). The data are drawn from a detailed longitudinal study of an eight-year-old Russian-speaking child who was acquiring English as L2 in the USA. It is first shown that the emergence of tense-aspect morphology patterns by aspectual verb class. However, contrary to the Aspect-before-Tense Hypothesis, it is argued that the acquisition patterns cannot be attributed to "defective" tense, nor do they reflect the spell-out of aspectual features. A new approach to the data is developed that proposes underspecification of the syntactic aspectual head in early L2 child grammar.


Paying a maintenance fee for licensed software is one way of getting corrective, perfective and adaptive maintenance done, in whole or in part. This paper reports on the experience of Cadence Design Systems, Inc. in modifying its software licensing fees. The paper gives background on Cadence, and reviews the historical development of the software licensing maintenance fee. The paper then summarizes the current pressures for changes in licensing practices and maintenance fees to fit customer needs better, and describes the experience Cadence has had with the changes it adopted. The paper closes with four lessons learned relevant to software maintenance. © 1997 John Wiley & Sons, Ltd.


Aim: In order to decipher the mechanisms
underlying the known protective effects of the thermal water from
Uriage-les-Bains (TWFULB) on the skin barrier function, we studied its antioxidant
properties as well as its effect on the expression of the tight-junctional
protein claudin-6, a candidate tumor suppressor factor. Study Design/Methods: In a
first step, TBARS and SOD activity assays were performed in an in vitro model of human dermal fibroblasts
treated by hypoxanthine/xanthine oxidase (HO/XO) mixture, in order to evaluate
the own antioxidant effect of the thermal water. In a second step, human
keratinocytes irradiated or not by UVB were used to evaluate the protective
role of TWFULB on nuclear DNA damage using a comet assay. In a third step, an ex vivo model of human skin explants
irradiated or not by UVA and UVB was used to evaluate the effect of TWFULB on
the intracellular catalase activity and on the cutaneous claudin-6 expression. Results: TWFULB showed
significant protective effects against oxidative stress induced by HO/XO: the
cell viability was improved and the lipid peroxidation was reduced. The tested
thermal water also showed significant SOD-like activity and protective effect
on the UVB-stressed DNA. Considering the ex
vivo models of skin explants,
TWFULB was able to counterbalance the "negative" effect of UVB on the intracellular
catalase activity and on the cutaneous claudin-6 expression.Conclusion:
This multiparametric approach shows the antioxidant
activity of TWFULB and emphasizes its role in the DNA protection of the
cutaneous tissue in front of the UV irradiations, and finally suggests that
some effects could involve the candidate suppressor functions of claudin-6.


Introduction The Hummers method is widely used for oxidation of graphene, despite resulting in a surface with structural defects that degrades its characteristics, compromising its usability in high-performance devices. An alternative approach for oxidizing graphene using reactive atomic oxygen produced from oxygen molecules decomposed by a 1500oC tungsten filament in an ultrahigh vacuum (UHV) to form graphene oxide (GO) with thermal reversibility at 260oC has recently been reported. 1 However, performing annealing treatment in UHV makes this method costly. Here, we presented a simpler and more cost-effective way to oxidize graphene layer through UV (ultraviolet)/O3 (ozone) treatment and reduce the resulting GO through UV irradiation. Both oxidation and reduction were performed at ambient temperature in atmospheric pressure. The existence of chemical bonds between oxygen and graphene was confirmed from the XPS (X-ray photoelectron spectroscopy) spectra and directly observed by STM (scanning tunneling microscopy) topography. Moreover, changes in electrical properties of a single layer graphene-based field-effect transistor (GFET) were also investigated. In previous works, we examined the thermal reversibility in electrical properties of a two-layer G-FET after being oxidized through UV/O3 treatment. 2 A decrease in conductivity and carrier mobility was observed after oxidation, but the electrical properties recovered after subsequent H2/Ar annealing, indicating that the oxidation with UV/O3 treatment was thermally reversible. However, in current study we focused on the feasibility of non-thermal reduction of GO by UV irradiation which is more cost-effective than annealing in UHV.

This paper deals with the synthesis of hexagonal-shaped silver nanoplates with diameters ranging from 15 to 20nm along with a smooth nanobulk of 120 nm. These nanoplates were prepared by a kinetically controlled solution growth method using mild reducing agent dextrose, polyvinylpyrrolidone (PVP Mw 40 k Da) as the capping agent and urea as a habit modifier and at a moderate temperature of 50°. The crystal structure of the highly faceted particles consists mostly of (111) surfaces as revealed by both X-ray diffraction (XRD) studies and transmission electron microscopy (TEM).

A new test procedure for connections assembled with mechanical fasteners is presented. The procedure provides information on cyclic and dynamic characteristies that will allow the relative performance of connections manufactured with different materials to be directly compared. An equivalent energy elastic-perfectly plastic system is defined that allows comparison of initial stiffness, yield load, and ductility on an equivalent basis. The hysteretic and equivalent viscous damping are also determined to provide information on the energy dissipation characteristics of the connection. Adoption of this test procedure will provide information that will allow engineers and architects to evaluate the performance of competing materials with direct comparisons. It will also provide uniform data from which revisions to the model building codes and design specifications for each material can be made on an equivalent basis.


abstract:In contemporary U.S. public discourse, calls for achieving equity abound. Many metrics now measure equity being achieved. I inquire into whether equity can be said to be achieved and still be equity. Inquiring as such leads me to excavating the menacing and actual cultural violence of developing such achievement. Simultaneously, this excavation shows the rhetoric of equity qua equity as a means of abolishing the conditions for that violence to take hold. I put forward that equity cannot be said to be achieved without the conditions of possibility equity offers being colonized. If a commitment to antiviolence speaks, it cannot say, "Equity achieved."
