A nuclear multiplate camera has been constructed to observe nuclear processes resulting from the bombardment of rectangular target of some extent with a neutron beam. Twelve Ilford K-Z plates are held in a rigid geometry which allows simultaneous measurements of nuclear reaction at the angles of 15°, 30°, 45°, 60°, ...and 165°. In this paper the determination of counting efficiency of the nuclear plate is described. A scheme of a numerical calculation for the counting efficiency is programed and carried out. As a check measurements of efficiency are made by counting the number of n-particles on the nuclear plates from Po-210 source electro-plated on the target. The results are in good agreement with the calculated ones.


With the implementation of life-long education theory,the expansion of university scale and construction of harmony society university,student administration is getting more and more important.But the current situation of university student administration is unoptimistic.The main reason is the absence of parent education.Under the new situation of harmony society construction,the university students' parents can't stand by side.Parent themselves,their children and the other society members all call for parent taking part in university student administration.Break a brand new way of student administration by parent education.We can not only draw lessons from parent education of primary education period,but also develop the resource superiority of university and conform to the tide of social development.


T H E want of a handy edition of the text of the Greek lyric poets has long been felt, and these small volumes supply it very satisfactorily. There is no preface, and it is not stated what text is followed; but where I have made any detailed comparison, it seems to keep pretty close to that of Bergk. Each volume has an excellent double index. When we ask what should be included in a volume of this title, we are at once met by the difficulty that there is no satisfactory definition of lyrical poetry. The term did not come into use till a late period, and even then was used vaguely. The modern theory which defines a lyric as a poem expressing some single emotion, and so distinct on the one side from narrative and on the other from reflective poetry, is quite foreign to ancient criticism, and cannot well be applied to ancient poetry. What the name practically means to us in Greek literature is (1) the song, including the lyrical portions of tragedy and comedy, and such forms as the scnlion, the hymenaeus, or the eiresione; and (2) poems written in certain defined metres which as a matter of fact are suitable (airi irelpas fyj/toKec) to the expression of emotional poetry. So long as we confine ourselves to these melic poems, the task of selection is pretty plain ; though the definition, wide as it is, would not cover the two noble hexameters of Eumelus with which this collection most fitly opens, nor the famous 'AKaxdra of Erinna. But when we admit poems written in the elegiac and iambic metres as lyrical, difficulties appear at once. There is no difference of kind between these iambic pieces and many fragments of speeches from lost dramas ; yet it is precisely the speeches in dramas that we call distinctively the non-lyrical portions. Again, it would seem strange to exclude Theognis from the lyric list. But no one calls Propertius a lyric poet. And if we admit Theognis, how are we to exclude the epigrammatists? Herr Pomtow has here thrown theory overboard altogether, and admits any fragment of poetry otherwise unclassed of a date anterior to 300 B.C. Sometimes the results are curious. When Bergk prints the epigrams attributed to Sappho or Simonides, it is sufficient justification that these were essentially lyrical poets, and that it is therefore proper to include everything they wrote, or were supposed to have written. But when Herr Pomtow prints sepulchral and votive inscriptions from Kaibel or the Corpus Inscriptionum, the case is different. For instance


In this paper, recognition of ancient middle Persian documents is studied. Our major attention has been focused on feature extraction and classification. A set of invariant moments has been selected as the features and the minimum mean distance (three versions of which that is called MMD1, MMD2, MMD3), KNN and Parzen as the classifier. Preprocessing is also considered in this paper which allows, the effects of under sampling (resolution pyramids), smoothing, and thinning be investigated. The algorithm has been tested not only on the original and smoothed images but also on the skeletonized and under sampled version of the text under test. The results show an acceptable recognition rate with the selected features with the proposed processing for the middle age Persian. The best-achieved classification rates are 95% and 90.5% for smoothed and original character images respectively. It was interesting to note that KNN and MMD2 classifiers yielded better recognition rate.


Recent research has started to apply environmental dynamic stochastic general equilibrium (E-DSGE) models for climate policy analysis. However, all of the studies assume a closed economy setting, where there is no interaction of the economy with an outside economy; this paper fills the gap by constructing a two-city E-DSGE model that features labor migration. With the model, we solve for the optimal environmental tax rate determined by a Ramsey social planner, who maximizes household utility and takes into account the policy's impact on labor migration. We find the following. (i) The optimal environmental tax rate should be more volatile and procyclical than the rates predicted in the aforementioned literature. (ii) In the closed economy setting, a higher environmental tax rate would always dampen production, while in our setting, it could stimulate output through deterring labor outflow and attracting labor inflow. (iii) We complement the existing literature by emphasizing that the optimal environmental tax rate in a city should respond not only to the shocks that occur internally, but also to those that occur in the opponent city. In particular, we find that it is optimal to reduce the environmental tax rate if a positive total factor productivity (TFP) shock occurs in the neighbor city.


Article 33 paragraph (3) of the 1945 Constitution of the Republic of Indonesia implies that the natural resources which belong to the State are used for the prosperity of the people of Indonesia. Thus, in carrying out the mandate of the Constitution to create justice for the community and national economic development of employment including foreign workers, the government should provide a good mechanism and supervision so that there will be no gap between the mandate of the constitution and the acceleration of economic development involving foreign workers. Labor inspection done by a separate working unit in the agency whose scope of duties and responsibilities is in the field of employment is in the central government, provincial government, and district/ city government. This study used a normative-empirical approach, where the researcher examined the law and its implementation regarding the roles of district/ city governments in the supervision of foreign workers. The purpose of this study was to examine the extent of the roles of district/ city governments in overseeing foreign workers in their regions. The results of the study showed that the roles of district/ city governments in carrying out the supervision of foreign workers in Indonesia were not regulated by laws of No. 23 of 2014 concerning regional government, PP No. 20 of 2018 concerning the use of foreign workers, and Minister of Manpower Regulation No.10 of 2018 concerning procedures for the use of foreign workers. Thus, its implementation made it difficult for district/ city governments to oversee the presence of foreign workers in their areas.

With the rapid development of economy, urbanization and population increasing, the frequency of city fire and the economic loss are rising. According to the characteristics of city fire, a prediction model of city fire accidents by applying basic principles and features of neural network is established. In order to predict city fire accidents more accurately, the city fire accidents are classified into the peak period (during spring festival) and the non-peak period. The method is exemplified in a city successfully. The result shows that the model could be taken as an effective tool to predict city fire accidents and could accurately predict the occurrence tendency of city fire accidents when combined with the time period classification.


This paper presents the design and experimental results of an FPGA-based cochlea filter tuning control block that emulates the active nonlinear behaviour of outer hair cells (OHC) in the cochlea. The tuning block uses data measured from physiological experiments which are mapped into adaptive voltage bias of a CMOS cochlea-mimicking filter channel to tune it. It extracts signal level from inputs to the cochlea channel and feedforwards the corresponding voltage bias to the tuning stage of the filter channel. A level-dependent control of the filter gain and quality factor was observed in the measurement results. The tuning control block nonlinearly compressed wide range of audio input distinctively into about 20 dB, which is the active gain inherent in the sample cochlea channel used. Based on this work, we will be able to build an intelligent audio front-end for future machine hearing systems that is able to adaptively process sound and cope with wide dynamic sound input like the cochlea does.


For the future high temperature superconductivity, HTS, series products new refrigerators are essential. Demands are made on these which are only partly fulfilled by refrigerators available in the market today. This refers to cooling power, initial cost and in particular reliability. Without proper refrigeration techniques it will be almost impossible to bring HTS products to the market. Based on the experiences made by the construction and operation of HTS prototypes within our company, like the 400 kW motor, 1.2 MVA current limiter and 1 MVA traction‐transformer provided with refrigerators which are available in the market today, criteria have been established to identify the future technical and economical requirements. These criteria apply to efficiency, maintainability, operation flexibility, feasibility of integration and performance/cost ratio. For the temperature range of 20 K to 77 K cooling with Gifford‐McMahon, Pulse Tube, Stirling and Mixture‐Cascade refrigerators are applicable. The developme...


Two methods for the ready preparation of some protected primary amine-functionalized (meth)acrylamide derviatives from amino halides or amino alcohols are described. The (meth)acryloyl moiety is introduced either in the last step from unsymmetrically N,N'-disubstituted diamines or, more simply, in the first step, but that demands a special work-up of the reaction mixture in order to prevent polymerization. Both methods are complementary. Reverse phase suspension polymerization of the title compounds with N-acryloylpyrrolidine and N,N'-ethylenebis(acrylamide) directly affords new beaded, high-loaded amine-functionalized resins for solid phase peptide synthesis.

Aims Non-targeted lipidomics analysis was conducted in post-mortem human frontal cortex area 8 (GM) and white matter of the frontal lobe centrum semi-ovale (WM) to identify lipidomes in middle-aged individuals with no neurofibrillary tangles and senile plaques, and cases at progressive stages of sporadic Alzheimer's disease (sAD). Methods Lipidomic analysis using an LC-MS/MS platform was carried out in selected cases with suitable post-mortem lacking co-morbidities and concomitant brain pathologies. Complementary data were obtained using RT-qPCR and immunohistochemistry. Results The WM shows an adaptive lipid phenotype resistant to lipid peroxidation, characterized by a lower fatty acid unsaturation, peroxidizability index, and higher ether lipid content than the GM. Changes in the lipidomic profile more marked in the WM than in GM occur in AD with disease progression. WM alterations are characterized by a decline in the content of branched fatty acid esters of hydroxy fatty acids (FAHFA), diacylglycerols (DG), triacylglycerols (TG), glycerophospholipids (GP) (especially ether lipids), and sphingolipids (especially sulfatides, ceramides, and glycosphingolipids). The GM acquires a fatty acid profile prone to peroxidation in sAD, while WM reinforces its peroxidation-resistant trait. Transcriptomic data point to additional defects of peroxisomal function. Conclusions Four functional categories are associated with the different lipid classes affected in sAD: membrane structural composition, bioenergetics, antioxidant protection, and bioactive lipids, with deleterious consequences affecting both neurons and glial cells favoring disease progression.

PC-based project management software (PMS) packages exist for sophisticated applications, and have relatively low installation and running cost. This has made PMS more accessible for small and medium-sized contracting firms. Although the PMS packages' functionality have been enhanced in many areas, two problems have been encountered, namely that packages are difficult to learn and complex to use. One solution is to develop stand-alone, knowledge-based systems for the construction industry. But, these are not available for small or medium-sized companies using PC-based PMS packages. This paper presents an effective approach to the implementation of PMS by means of an interactive program in a fire protection contracting company.


Background:
 Although some studies have reported variation in out-of-hospital cardiac arrest (OHCA) survival by neighborhood and geographic region, little is known about variation in OHCA survival at the level of EMS agencies—which, unlike neighborhoods and regions, may have modifiable resuscitation practices.

 Methods:
 Within the national Cardiac Arrest Registry to Enhance Survival, we identified 258,320 non-traumatic OHCAs from 764 EMS agencies with ≥10 OHCAs annually between 2015-2019. Using multivariable hierarchical logistic regression, we computed risk-adjusted rates of survival to hospital admission for each EMS agency. We quantified the extent of variation in survival with the median odds ratios (MOR) and assessed the extent to which variation in survival was explained by two EMS agency resuscitation practices: time from 911 call to EMS arrival and the proportion of OHCAs at each EMS agency with termination of resuscitation (TOR) without meeting TOR futility criteria.

 Results:
 Of 258,320 persons with OHCA, mean age was 62.2 ± 17.0 years and 36.1% were female. Overall, 85.0% were of presumed cardiac etiology, 82.3% occurred at home, 44.0% were witnessed by a bystander, and ~75% were due to a non-shockable initial rhythm. Across the 764 EMS agencies, the median risk-adjusted rate of survival to hospital admission was 27.4% (IQR, 24.5% - 30.2%). The adjusted MOR was 1.35 (95% CI: 1.32, 1.39), suggesting that the odds of survival to hospital admission after an OHCA varied by 35% in two identical patients in one randomly selected EMS agency vs. another. EMS agencies in the lowest quartile of risk-adjusted survival had a mean EMS response time of 12.0 ± 3.4 minutes, whereas those in the highest quartile had a mean EMS response time of 9.0 ± 2.6 minutes (
 P
 <0.001). The mean proportion of OHCA cases where CPR was terminated in the field without meeting TOR futility criteria was 27.9% ±16.1% in quartile 1 and 18.9% ±11.4% in quartile 4 (
 P
 <0.001). Adjustment for the EMS-level variation in both resuscitation practices attenuated the MOR to 1.30 (95% CI: 1.27, 1.33).

 Conclusions:
 Rates of survival to hospital admission for OHCA vary significantly by EMS agency, and some of this variation in survival is explained by differences in EMS arrival time and TOR practice patterns.


Despite an increasing focus on the importance of temporality, time, and timing in international relations (IR) and security studies, there has been relatively less movement toward thinking about the temporal present as a conceptual area of inquiry. This article argues that taking the present seriously as a concept, method, and theoretical area of analysis offers unique value for the study of war. Paying attention to the manner in which the present time of war (wartime) is sociopolitically articulated as a space of temporal exception exposes how it is understood as diverging from representations of politics, past and future. It also foregrounds war's irreducible temporal dimension and exposes the relational bases of wartime's apparent universality. This article uses a close reading of Clausewitz's On War (1832) as generative dialogue and illustrative example, showing how an awareness of the importance of temporal dynamics—particularly, the concept of the present—is both valuable and workable in the study of war. A temporal imaginary of war centered on what Hutchings calls the "heterotemporal" present enhances inquiry into contemporary political violence, the ontology of war, and the emergent attributes of collective violence.


The magnetic phase diagrams of two Cr‐Mo‐Si systems have been determined from electrical resistivity, ultrasonic wave velocity, and thermal‐expansion measurements. The concentration dependence of the Neel temperature of (Cr0.97Mo0.03)1−ySiy was explained in terms of changes in the density of states and pair breaking effects on alloying. For (Cr1−xMox)0.986Si0.014 the magnetic phase diagram was explained by taking changes in the nesting parameter to be the dominant effect.


The Chinese widely settled in Serbia in the 1990's. There is no official data on the real number of the Chinese living in Serbia. Most of the Chinese live in New Belgrade, near the shopping center at Block 70. Media images of the Chinese community in Serbia, especially in Belgrade are at the level of urban legend. Those are stories about their number, nutrition, non-dying fictitious mixed marriages, etc. Knowledge of contemporary Serbs about the Chinese mainly exists at the level of media information or it is based on contacts with representatives of the Chinese community in Serbia. In this sense, there are two different kinds of stereotypes among the Serbs about the Chinese. Some are related to the picture of the Chinese Chinese, i.e. Chinese in China, and others are pictures of the Serbian Chinese, i.e. Chinese who live in Serbia. Association differs according to age structure and depending on which part of the city examinees live in. Almost all of the older examinees, regardless of gender and education, emphasized the difference between the Chinese population in China and those in Serbia. In addition, films made a significant role in getting to know Chinese culture. Association with Bruce Lee and Jackie Chan appeared to the words China and Chinese among examinees of all ages. How ethnic hetero-stereotypes about the Chinese in Serbia will continue to change depends on different factors. First of all, on social and political factors and images of someone else mainly created through the media.

A review is given of the cavitation observation techniques as used in the NSMB Depressurized Towing Tank. Special attention is paid to those observation and recording techniques which are suitable for studying the time-dependent behaviour of propeller cavitation. The paper also includes the description of a method, based on stereo photogrammetry, to determine the topology of the cavity on a propeller blade.


Based on the success achieved in other industries, there is the potential for the Architectural, Engineering, and Construction industry to achieve significant improvements in efficiency through the adoption of e-business methods and solutions. There are a variety of issues that must be considered in steering the industry toward these improvements. The issues stem from the root characteristics of the industry including: fragmentation, highly pragmatic, cost conscious, little institutional leadership, and no standards in technology and business models. This paper examines e-procurement as a subset of e-business in an effort to identify the issues surrounding the development of a critical mass of participants required to overcome the organizational and technology challenges. The issues are discussed in some detail followed by the presentation of some preliminary results from a survey which quantifies the current status of the industry in an attempt to support a strategy for progress.


Early detection of photoreceptor dysfunction is essential for preventing vision loss due to retinal degenerative diseases, such as age-related macular degeneration (AMD) and inherited retinal degenerations (IRDs). Functional intrinsic optical signal (IOS) imaging promises a high-resolution method for objective optoretinography (ORG). Stimulus-evoked photoreceptor-IOS has been recently demonstrated in healthy animal and human retinas. The fast photoreceptor-IOS response was found to occur at the photoreceptor outer segment (OS) right after the onset of retinal stimulation. However, in vivo IOS response of photoreceptor dysfunctions is not yet validated, which is essential to measure the clinical usability of ORG measurement. In this study, we report in vivo IOS imaging of rod photoreceptor dysfunction in retinal degeneration 10 (rd10) mice. A custom-designed optical coherence tomography (OCT) was used for photoreceptor-IOS imaging. A significant attenuation of the photoreceptor-IOS was found in rd10 mice due to disorganized ultrastructure of the photoreceptor OSs, which appeared ahead of progressive rod cell death. Our experiments demonstrate that fast photoreceptor-IOS is highly sensitive to ultrastructural integrity of the photoreceptor OSs. We anticipate that quantitative imaging of fast photoreceptor-IOS will provide objective ORG measurement to advance the study and diagnosis of AMD, IRDs, and other retinal diseases that can cause photoreceptor dysfunctions.


Software-Defined Networking (SDN) benefits from the development flexibility of control-plane applications (SDN-Apps), which allows third parties to make contributions. Such flexibility may expose SDN networks to security threats, since SDN-Apps may be malicious or prone to implementation bugs. These buggy/malicious SDN-Apps may contaminate the data plane with abnormal network actions, which may not be prevented before they are committed to the data plane. This contamination may lead to network crash or poor network performance. We thus present ReSDN, a lightweight solution for data-plane state recovery, to recover an SDN data plane from a contaminated state. It requires neither switch modification nor the intervention of SDN-Apps, both of which current recovery solutions rely on. It leverages the concept of FP-tree (Frequent Pattern tree) to maintain the dependency of event transactions and network actions to achieve correct recovery. Our evaluations validate the viability of our ReSDN design, and show that it can recover more than twice as fast as the other type of recovery approach, rollback recovery.


We each possess certain objects that are dear to us for a variety of reasons. They can be sentimental to us, bring us delight through their use or empower us. Throughout our lives, we use these cherished possessions to reaffirm who we are, who we were and who we wish to become. To explore this, we conducted a design study that asked ten participants to consider their emotional attachment towards and the identity-relevance of cherished and newly introduced possessions. Participants were then asked to elaborate on their responses in interviews. Through a thematic analysis of these responses, we found that the emotional significance of possessions was reportedly influenced by both their relevance to selfhood and position within a life story. We use these findings to discuss how the design of new products and systems can promote emotional attachment by holding a multitude of emotionally significant meanings to their owners.

Phospahting coated WE43 magnesium alloy was prepared by an immersion method.The microstructure,corrosion resistance and biocompatibility of the coated alloy were investigated.Scanning electron microscopy(SEM) and X-ray diffraction (XRD) were used to examine the microstructure and the composition of the coated alloy.The corrosion resistance was studied by means of potentiodynamic polarization method and the biocompatibility of the surface modified WE43 alloy was evaluated by (3-(4,5)-Dimethylthiazol-2,yl)-2,5-diphenyltetrazolium bromide(MTT) and hemolysis test.The results show that the phosphating coating can enhance the corrosion resistance of WE43 alloy and can be a good candidate to increase the biocompatibility of WE43 alloy.


The effects of reaction temperature, methane partial pressure, and reaction period on growing single-walled carbon nanotubes (SWCNTs) are demonstrated in the present study. Simple methane CVD is carried out using a homemade iron nanoparticles catalyst. The iron nanoparticles are prepared by spin-coating a colloidal mixture of iron(III) nitrate, PEG-400, and absolute ethanol on silicon wafers. The experimental results show that the effects of all three reaction parameters studied, on the morphology and the topography of the SWCNT arrays, are significant. There is no evidence showing that the diameter of SWCNTs is correlated with these three reaction parameters.


Atomistic simulations of electron and phonon transport are performed within the non-equilibrium Green's function formalism to analyze the thermal and electrical properties of graphene nanoribbons (GNRs). We predict that by patterning GNRs properly, a strong enhancement of thermoelectric properties can be achieved. From the study of edge orientation effects, we propose a strategy likely to degrade the thermal conductance while retaining high electronic conductance and thermopower. An effect of resonant tunneling of electrons is evidenced in mixed GNRs consisting in alternate zigzag and armchair sections or in perfect GNRs with vacancies. Combining these effects, an optimized structure able to provide a high thermoelectric factor of merit ZT exceeding unity at room temperature is demonstrated


The origin of Moho has been debated since its discovery at the beginning of 20 th century (Prodehl et al., 2013, Tectonophysics 609). Moho is, however, absent in many oceanic regions (as much as 40 %). (Mutter & Carton, 2013, Tectonophysics 609). Ohira et al. (2017, EPSL conducted an active-source reflection and refraction survey to investigate crustal structure and Moho characteristics along a > 1000 km profile in a Pacific Ocean basin. Clear oceanic Moho reflections had been observed only at the southwestern end of the profile (~50 km) and Moho reflections were diffused, weak, or absent along most parts of the profile (~1000 km). Ohira et al suggest that the unclear Moho reflection events may correspond to a thick intermediate lithology between mafic and ultramafic. As a matter of fact, the contact between mantle peridotite and layered gabbro from the lower oceanic crust in the Oman ophiolite is ultramafic, usually underlined by a dunitic transition zone (DTZ), mostly made of olivine + scattered Cr-spine with few mafic intervals (less than 10 % and mostly


We report on a study that finds a positive correlation between black hole mass and variability amplitude in quasars. Roughly 100 quasars at z<0.75 were selected by matching objects from the QUEST1 Variability Survey with broad‐lined objects from the Sloan Digital Sky Survey. Black hole masses were estimated with the virial method using the broad Hβ line, and variability was characterized from the QUEST1 light curves. The correlation between black hole mass and variability amplitude is significant at the 99% level or better and does not appear to be caused by obvious selection effects inherent to flux‐limited samples. It is most evident for rest frame time lags of the order a few months up to the QUEST1 maximum temporal resolution of about 2 years. The correlation between black hole mass and variability amplitude means that the more massive black holes have larger percentage flux variations. Over 2–3 orders of magnitude in black hole mass, the amplitude increases by ∼0.2 mag. A likely explanation for the c...


Wireless data traffic in cellular networks is currently undergoing a strong global expansion and the demand for high and reliable data throughput increases. Capacity is, however, a limited resource, and in radio resource management a trade-off has to be made between the congestion level, related to cell coverage and interference levels, and the Quality of Service (QoS) or data rates of the users. The radio channel conditions vary on a fast time scale and the measurements of the received signals are subject to disturbances and uncertainties. This motivates the use of control strategies to update the transmission powers. In fact, in implementations of uplink in cellular networks, the performance of the network is ensured by using a fast inner power control algorithm to track a QoS-target and a slower outer control algorithm to limit congestion. Several theoretical challenges arise in this problem setting. Due to the nature of the network, both information and control are distributed. Furthermore, measurements of the congestion and the QoS are used in the control loops, which introduces nonlinear feedback. Another complicating factor is that filtering, computations and information exchange in the network cause time-delays and dynamics. In this thesis we address these challenges by using modeling and analysis tools in systems and control. The objective is to provide systematic methods to quantify the fundamental limitations of the system and to point out the trade-offs for a given system design. We perform stability analysis on a high mathematical level that provides results that are simple to compute and that reveal the system structure.In Paper A we extend existing power control models and stability frameworks to include dynamics. For this we use a general definition of the interference. Moreover, stability is addressed by a monotonicity approach and by proposing a Lyapunov function. Paper B provides less conservative stability results using input-output analysis for the same system model. Stability of a linearization of the system model is studied in Paper C with the multivariate Nyquist criterion. Moreover, we use discrete multivariate describing functions to analyze the equilibrium oscillations that arise due to binary feedback. In Paper D we extend the model with an outer control loop, which dynamically sets the reference value to the control algorithm studied in Papers A to C. The main analysis tool for stability is input-output theory.


Background: Acute minor ischemic stroke (AMIS) or transient ischemic attack (TIA) is a common cerebrovascular event with a considerable high recurrence. Prior research demonstrated the effectiveness of regular long-term remote ischemic conditioning (RIC) in secondary stroke prevention in patients with intracranial stenosis. We hypothesized that RIC can serve as an effective adjunctive therapy to pharmacotherapy in preventing ischemic events in patients with AMIS/TIA. This study aimed to investigate the feasibility, safety, and preliminary efficacy of daily RIC in inhibiting cerebrovascular/cardiovascular events after AMIS/TIA. Methods: This is a single-arm, open-label, multicenter Phase IIa futility study with a sample size of 165. Patients with AMIS/TIA receive RIC as an additional therapy to secondary stroke prevention regimen. RIC consists of five cycles of 5-min inflation (200 mmHg) and 5-min deflation of cuffs on bilateral upper limbs twice a day for 90 days. The antiplatelet strategy is based on individual physician's best practice: aspirin alone, clopidogrel alone, or combination of aspirin and clopidogrel. We will assess the recurrence rate of ischemic stroke/TIA within 3 months as the primary outcomes. Conclusions: The data gathered from the study will be used to determine whether a further large-scale, multicenter randomized controlled Phase II trial is warranted in patients with AMIS/TIA. Trial Registration: ClinicalTrials.gov, NCT03004820; https://www.clinicaltrials.gov/ct2/show/NCT03004820.


Current popular culture is connected to the birth of a secular and materialistic interpretation of reality, partly brought about by accounting and the principle of profit maximisation. Materialism, which is the tendency to be more concerned with material values, through rational experimentation and discourse – so people were given to believe – would solve all of the fundamental issues related to human governance and development. With education and legislative action, people's happiness would be determined, according to materialism, by better health, better food, better education and better living conditions. First, this paper applies Foucault's genealogy, to explain that materialism is a product of a series of historical events that are closely related to the need to keep account and the practice of accounting. Second, this paper seeks to show that, accounting and 'scientific materialism' has been instrumental in paving the course to their and our common failure. Third, the paper proposes a shift away fro...


Cotton is a major fiber crop of global significance, cultivated in more than seventy countries in the world. Cotton crop is playing an important role in economic, political and social affairs of the world. Cotton belongs to the family "Malvaceae" and genus "Gossypium". Cotton crop as commercial commodity plays an important role in industrial activity of nation, in terms of both employment generation and foreign exchange, hence it is popularly known as "White Gold" and "Friendly Fiber". Major cotton growing states are Maharashtra, Madhya Pradesh, Gujarat from Central Zone, Andhra Pradesh, Tamil Nadu, Karnataka from South Zone and Punjab, Haryana, Rajasthan from North Zone. In Maharashtra, cotton is grown over an area of 41.98 lakh hectares with total production 85 lakh bales and an average productivity is 344 kg per hectare (Anonymous, 2018).

Enthalpy changes at 31 °C have been measured on mixing di- and tri-ethylene glycol dimethyl ethers with selected n-alkanes in the range decane to heptadecane, and volume changes at 31 °C on mixing diethylene glycol dimethyl ether with the n-alkanes. The experimental results are compared with the predictions of Prigogine–Flory theory.


Emergent order in complex dynamic systems is a concept that is both important to a wide variety of fields of science and difficult to understand and teach. Recent advancements in interactive and tangible interfaces point towards the possibility of new tools which can help with both the analysis and simulation of complex systems, while also making the systems dynamics more approachable and easier to understand for students. This paper describes an experimental tangible interactive interface designed to make the complex and emergent behavior of ant colony foraging more understandable. We present the system design, its interactive capabilities, and discuss evaluation methods for further studies.


We report the development of a model-based leaping/flipping quadruped robot. The planar model contains a planar rigid body and two compliant legs to investigate how forces are transmitted from the ground to the body through the foreleg and the hindleg and the resultant forces and moment on the body. The spring-loaded compliant leg with rolling contact was chosen for analysis, while the widely-used spring-loaded compliant leg with point contact was also developed for comparison purpose. The model's equations of motion (EOM) were derived for four modes: double stance, hindleg stance, foreleg stance, and flight. Moreover, the factors of initial pitch angle and relative actuation timing that affect whether the motion is a forward leap or a flip were investigated. The results indicate that different factors dominate different indices of the leaping/flipping motion—body pitch variation is mainly determined by the initial pitch angle; lift-off angle is determined by the delay of the foreleg; and stance time is affected by the delay of the hindleg. The same parameters were applied and evaluated in a robot that exhibited the leaping and flipping behaviors predicted by the model.

A software based IEEE 802.11a digital baseband transmitter has been implemented on a highly parallel single-chip DSP. The processing platform is a programmable and reconfigurable asynchronous array of simple processors (AsAP) that is well matched to complex system workloads such as 802.11a. The transmitter is the first fully-compliant 802.11a software implementation, and is the first full-rate software implementation. The transmitter also complies with the high-rate portions of the 802.11g standard. It operates over all 8 data rates, includes additional upsampling and filtering functions, and sustains transmissions at 54 Mb/s on a 22-processor array; it is expected to occupy less than 20 mm/sup 2/ in 0.18 /spl mu/m CMOS.

Silica is an important industrial chemical but the mechanisms involved in its formation from aqueous precursors remain far from well understood. In this study we have prepared a range of silicon catecholate salts where M+ is Li+, Na+, K+, NH4+, Et3NH+ and followed complex breakdown and silica oligomerisation under approximately neutral pH conditions by 1H solution NMR and a molybdenum blue colorimetric method. The silicas produced have been analysed by electron microscopy and gas adsorption methods to give information on particle sizes and their distribution, surface areas and porosity. The oligomerisation reaction is complex but it is possible to identify time periods over which principally dimers, trimers and higher molecular weight oligomers are formed. In the first case, no loss of orthosilicic acid from solution is measured; in the second case, apparent third-order kinetics with respect to loss of orthosilicic acid from solution are observed; in the third case, a reversible first-order reaction is observed and information is obtained for both polymerisation (k+) and depolymerisation (k–) processes. Once ca. 95% of the available silicon has been polymerised, the only process occurring is Ostwald ripening which cannot be measured reliably by the colorimetric method. The reaction rates and solubility of the soluble silicon species were found to vary with cation identity. Values for the apparent third-order section of the oligomerisation reaction gave rate constants with values between 9.66 × 10–6 and 5.02 × 10–5 l2 mmol–2 s–1 for Li+ > Na+, NH4+ > Et3NH+ > K+. Rate constants for the addition of one orthosilicic acid molecule to oligomers gave k+ between 1.27 × 10–3 and 2.74 × 10–4 s–1, with Li+ > Na+ > Et3NH+ > K+ > NH4+. An activation energy of 58 kJ mol–1 for this process was obtained for the K+ salt. The change in (k++k–) between the various Group 1 cations was found to vary linearly with the radius of the hydrated metal ions, but the situation was more complex for the NR3H+(R = H, Et) cations. The solubility of orthosilicic acid in the presence of NR3H+(R = H, Et) cations was lower than in the presence of Group 1 cations. This led to the production of higher levels of silica from the ammonium and triethylammonium salts.TEM and CRYOTEM were used to identify the size and nature of aggregates formed during the silica polymerisation reaction. From 10 min to 1 h of reaction time, material built up from ca. 1 nm particles was detected. After 3 h of reaction, particles were of the order of 2–3 nm in diameter and small aggregates of 5 + particles could be observed. Electron microscopy (TEM and SEM) of silica samples taken at the end of the reaction (ca. 7 days) showed that precipitation in the presence of counter-ions of increasing ionic radius resulted in an increase in average particle size from 2 to 20 nm in diameter and an increase in average aggregate size from 57 to 71 nm in diameter. Surface area data showed a reduction in measured surface area from 558 m2 g–1 for Li+ to 237 m2 g–1 for Et3NH+. Silica precipitated in the presence of lithium ions had spherical particles and spherical pores, and silica precipitated in the presence of triethylammonium ions had irregular shaped particles and slit shaped pores. The change in pore shape was progressive as the size of the counter-ion was increased.It is clear that counter-ion identity has a very significant effect on the kinetics of oligomer formation and, consequently, on the nature of the silica produced. The behaviour of the precipitating systems containing the Group 1 metal cations is related to the size of the hydrated metal cation. For the two cations based on ammonia, the arguments are more complex and involve size, hydrogen bonding and hydrophobicity effects.


The aim of the present paper is to investigate the surface waves in a non-homogeneous, isotropic, visco-elastic solid medium of nth order including time rate of strain. The theory of generalized surface waves has firstly been developed and then it has been employed to investigate particular cases of waves, viz., Stonely and Rayleigh, Love type. The wave velocity equations have been obtained for different cases and are in well agreement with the corresponding classical result, when the effect of viscosity as well as non-homogeneity of the material medium are ignored.

Modern cosmology has now emerged as a testing ground for theories beyond the standard model of particle physics. In this paper, we consider quantum fluctuations of the inflaton scalar field on certain noncommutative spacetimes and look for noncommutative corrections in the cosmic microwave background (CMB) radiation. Inhomogeneities in the distribution of large scale structure and anisotropies in the CMB radiation can carry traces of noncommutativity of the early universe. We show that its power spectrum becomes direction-dependent when spacetime is noncommutative. (The effects due to noncommutativity can be observed experimentally in the distribution of large scale structure of matter as well.) Furthermore, we have shown that the probability distribution determining the temperature fluctuations is not Gaussian for noncommutative spacetimes.

(1) Background: The thermal environment in a pregnant sow piggery is affected by physical parameters such as air temperature, relative humidity, and airflow velocity. However, it is challenging to conduct experimental studies due to the high cost. (2) Methods: Computational fluid dynamics (CFD) was used to study the distribution characteristics of airflow in a pregnant sow piggery with centralized ventilation. (3) Results: The results show that the maximum difference between the simulated and experimental temperature was less than 1.54 °C, and the simulated and tested relative humidity difference was less than 10% RH. Incorporation of a middle air outlet is beneficial for increasing the uniformity of temperature distribution, as studied by comparing the temperature and humidity uniformity coefficient of the two air outlet locations, but the uniformity of humidity distribution will be reduced. With an increase in velocity, the temperature shows a downward trend and the relative humidity shows an upward trend. (4) Conclusions: The most suitable position for the outlet is the middle, with an associated airflow velocity of 0.5 m/s. This study revealed the variation in flow field distribution and air distribution in the pregnant sow piggery as a consequence of changes in ventilation structure, which has certain significance as a reference for the optimization of airflow in intensive pregnant sow piggeries.


Abstract : In this study, the damage fields near the crack tip in edge-cracked sheet specimens subjected to a constant strain rate of 0.05 min-(exp -1) were investigated using real-time radiographic techniques. During the tests, Lockheed-Martin Advanced Technology Center's high-energy real-time x-ray system (HERTIS) was used to monitor damage initiation and evolution processes near the crack tip. The experimental findings indicate that x-ray technique is a promising technique to monitor damage evolution during crack propagation.

Abstract.  An unknown beetle collected in the Territorio Federal Amazonas, Venezuela, and designated as belonging to a new family, is described (as Meru phyllisaegen.n., sp.n.) and illustrated by line drawings and scanning electron micrographs. The new family, Meruidae, is diagnosed and assigned to the suborder Adephaga with a discussion of some characters and likely phylogenetic affinities. With a body length of 0.85–0.9 mm, M. phyllisae is the smallest known member of aquatic Adephaga. Based on the observed skeletal and behavioural characters to date, the taxon appears to represent the sister clade to the remaining families of Dytiscoidea, but also has features suggesting a close relationship among Noteridae and/or Haliplidae. A description and photographs of the habitat are included, with a list of other associated water beetle taxa. Some observations on the behaviour of captive beetles are given. The minute 'comb‐clawed cascade beetles' are known only from the type locality, El Tobogán, where streams flow among exposed areas of bedrock in the geologically ancient Guyana Shield region.


Non-fluorinated hydrocarbon cationic membranes have been developed for use instead of Nafion in Polymer Electrolyte Membrane Fuel Cells (PEMFCs), or at higher temperatures than 80 oC, or in fuel cells fed with alcohol. The aim of this work was to evaluate the performance of commercial non-fluorinated hydrocarbon cationic membranes with potential use in direct ethanol fuel cell (DEFC), and also evaluate the Gas Difusion Layer (GDL) and Gas Difusion electrode (GDE) prepared for use with them. Two hydrocarbon membranes (E-750 and P-730) produced by FuMATech/GR were analyzed according to their ion exchange capacity, water uptake in water/alcohol solution, morphology, chemical composition, thermal and viscoelastic behaviour, and conductivity by impedance. The GDLs were prepared by spraying an aqueous emulsion of Vulcan carbon/Teflon®, with and without emulsifier agent (sulfonated hydrocarbon resin), in both sides of a carbon fabric. The electrodes were prepared by the respective deposition of the electrocatalysts emulsions on the cathode and anode GDLs. The anodic and cathodic GDEs were prepared with 1 mg.cm of the electrocatalyst of PtSn/C 20% (75:15) and of Pt/C (20:80), respectively, which were characterized by SEM-EDS. The physicochemical properties of the hydrocarbon membranes were similar to the Nafion membrane ones. The potential values obtained in a DEFC prototype unit cell with FuMATech membranes were lower than those with Nafion-117 membrane. On the other hand, the performance of the DEFC prototype with Nafion-117 membrane was the same if used GDEs commercial or here prepared.


There have been continual attempts to identify alternatives to increase the agricultural output to improve the living standards of farmers, meet the current demand, and promote sustainability in commercial agriculture. Within this paradigm, low-temperature plasma (LTP) treatments have piqued the attention of investigators and are presently being extensively researched in the agriculture sector. A preliminary study was conducted on mustard seeds ( Brassica nigra) to examine the potential of LTP in agriculture to enhance germination and productivity. The seeds were subjected to LTP treatment for 1 to 4 min in an argon environment (11.7 kV, 50 Hz, and Q = 3 L/min) at atmospheric pressure. The germination and growth parameters of the untreated and treated seeds were calculated on the 16th day of the seeds' germination and compared. All germination and growth-related parameters were found to be improved in LTP-exposed seeds up to 3 min. However, the germination and growth-related parameters deteriorated in 4-min LTP-treated seeds compared to those of control and other treatment time seeds. The water contact angle and scanning electron micrograph images clearly indicated that there is a significant change in the seed coat after being exposed to LTP for a specific time period. The treated seed's texture was significantly rougher than that of the control, which is directly related to the hydrophilicity of seeds. The findings of this study suggest that using seeds exposed to LTP for a suitable time results in a considerable increase in the germination percentage of sown seeds while also hastening seedling growth and development.


The main drawback of previous Chinese character error detection systems is the high false alarm rate. To solve this problem, we propose a system that combines a statistic method and template matching to detect Chinese character errors. Error types include pronunciationrelated errors and form-related errors. Possible errors of a character can be collected to form a confusion set. Our system automatically generates templates with the help of a dictionary and confusion sets. The templates can be used to detect and correct errors in essays. In this paper, we compare three methods proposed in previous works. The experiment results show that our system can reduce the false alarm significantly and give the best performance on fscore.


A method is described that allows large amounts of fluid to be sealed into platinum capsules without loss of fluid during welding, and using a minimum amount of metal. After loading the solution and other starting materials into the capsule, a preliminary seal is obtained by pressing the capsule walls around an inserted disc of platinum. This mechanical seal, which is produced in a two-piece die compressed in a vice, prevents loss of volatiles during subsequent mounting of the closure lid by arc welding. The result is a short, cylindrical capsule with a regular geometry. We have tested this capsule preparation technique in 36 consecutive piston cylinder experiments in which Pt 95 Rh 05 capsules filled with aqueous solutions were subjected to 700-1100 °C and 1.0-3.5 GPa for 4-119 h. In 28 of the runs the amount of fluid lost during the experiment was less than 5 wt%. The new method is suitable for any kind of experiments in which volatile-rich charges need to be sealed into platinum capsules, and in which short capsules with a regular geometry need to be obtained.


We present results on diffractive production of hard processes in {anti p}p collisions at {radical}s = 1.8 TeV at the Tevatron using the CDF detector. The signatures used to identify diffractive events are the forward rapidity gap and/or the detection of a recoil antiproton with high forward momentum. We have observed diffractive W- boson, dijet, and heavy quark production. We also present results on double-pomeron production of dijets.


In accordance with the concept of additive technologies which is layer by layer synthesis of products, there is a need for a new approach to components design. One of the main tools to be operated is numerical modelling which can provide the designer with an integrated approach to the development of new products if applied skillfully. The numerical modelling, besides carrying out strength calculations, includes topological optimization and creation of cellular structures with the help of which it becomes possible to create light-weight products with preservation of required strength characteristics. In this paper both methods were applied based on the example of a mounting bracket: topological optimization and creation of cellular structures. The paper presents the results of calculating the stress-strain behaviour of the source and target structures, allowing to estimate the possible reduction in product weight and quantity of the consumable material when using an additive technology.


We have modeled parallel analog neural networks designed such that their evolution toward final states is equivalent to finding optimal (or nearly optimal) paths through decision trees. This work extends that done on the Traveling Salesman Problem (TSP)[1] and sheds light on the conditions under which analog neural networks can and cannot find solutions to discrete optimization problems. Neural networks show considerable specificity in finding optimal solutions for tree searches; in the cases when a final state does represent a syntactically correct path, that path will be the best path 70–90% of the time—even for trees with up to two thousand nodes. However, it appears that except for trivial networks lacking the ability to ''think globally,'' there exists no general network architecture that can strictly insure the convergence a state that represents a single, continuous, unambiguous path. In fact, we find that for roughly 15% of trees with six generations, 40% of trees with eight generations, and 70% o...


A description is given of a method capable of automatically forming efficient, high‐quality hybrid meshes for viscous flow calculations over complete aircraft, given engineers' requirements on mesh density and first cell‐height. Mixed quadrilateral/triangular surface grids are constructed using the moving‐front approach, with point placement and connection optimized to ensure high‐quality, anisotropic panels are generated. The volume mesh is built in two stages. A near field mesh is formed using the advancing‐layer approach, significantly enhanced through the use of mesh enriching/collapsing techniques and layer‐intersection detection/front‐termination algorithms. The remainder of the domain is then covered by a cut‐cell Cartesian mesh of varying density that conforms to the outer‐surface of the near field mesh. Examples of meshes generated using the described methods are presented and the user‐input discussed. Copyright © 2003 John Wiley & Sons, Ltd.


Al Ti C master alloys have been prepared with a novel production method. A combination of X ray phase analysis, SEM and EDS was used to examine the phases and microstructures of the master alloys. The master alloys have block like Al 3Ti particles and submicron size TiC X with X ranging from 0.49 to 0.78 and show excellent grain refining performance for commercially pure aluminum. Titanium carbides were observed at the crystallization centers in refined castings.


The aim of this study was to find a prenatal parameter to be able to predict possible prenatal complications or postnatal surgical options, thus allowing the fetal medicine specialist, together with pediatric surgeons and neonatologists, to improve the counseling of the parents and to determine the timing of delivery and therapy. This was a retrospective analysis of prenatal diagnosis and outcome of fetuses with 34 cases of gastroschisis between the years 2007 and 2017. A total of 34 fetuses with gastroschisis were examined and 33 outcomes registered: 22 cases of simple gastroschisis (66.7%) and 11 cases of complex gastroschisis (33.3%). A cut-off value of 18 mm for intraabdominal bowel dilatation (IABD) showed a positive predictive value (PPV) of 100% for predicting simple gastroschisis. IABD gives the best prediction for simple versus complex gastroschisis (cut-off of 18 mm). Extra-abdominal bowel dilatation (EABD) cut-off values of 10 mm and 18 mm showed low sensitivity and specificity to predict complex gastroschisis.

In order to solve problems such as low resources utilization of data center backbone bandwidth and expensive daily expenses caused by the tidal effect in the transition of large-scale network data, the new optimization method of bandwidth resource for bulk data transfer is proposed. This method finishes the bulk data transfer by taking full advantage of the idle channel bandwidth. Firstly, the dynamic idle network bandwidth resource was switched into the static flow network; and then the max-min fair multi-commodity flow model is built on the basis of static network; finally, the iterative technique is used to solve the programming model for getting the maximum transport flows and the corresponding transmission path of bulk data transfer. The simulation method was used to test this optimization project. The results show that the optimization method proposed by the paper can significantly improve the utilization of data center backbone bandwidth resource, and the maximum amount of data transmission and the speed of data transfer have been obviously increased


The purpose of this paper is to analyze the decisions of different farmers' household to return their contractual land. The method of this paper is to apply the B-Logistic model to analyze basing on the survey data of Chongqing. The results showed that 1)age of farmers' household head, the main family members to participate in the new agricultural insurance, the contract farmland area have a significant positive effect on the decisions of the real farmers' households to return lands, however, the number of family labor, homestead area, the quality of contracted farmland have a significant negative effect on the decisions of the real farmers' households to return lands. 2)The numbers of family labor, the average annual household income, average family farm income, homestead area, the quality of contracted land, the distance that the village from the town have significant negative effect on decisions of the typeⅠ of farmers' households to return land. While, the main family members to participate in the new agricultural insurance have significant positive effect on the decisions of the typeⅠ of farmers' households to return land. 3)Housing costs have significant negative effect on the decisions of the typeⅡfarmers' households to return lands. However, the average annual family income, average family farm income have a significant positive effect on the decisions of the typeⅡfarmers' households to return land. 4)The distance that the village from the town, the average annual family income, average family farm income has a significant positive effect on the decisions of the non-farmers' households to return land. 5)Overall, the factors that influence the real and typeⅠfarmers' households have greater similarity, and the factors that influence the non and type Ⅱ farmers' households have greater similarity. The conclusion is that the impact factors on returning land are significant different. The local government should put forward policies to encourage and guide the type Ⅱ farmers' households to return land.


N-uptake and N utilization of different fertilizer types by winter wheat – pot experiments with 15N

The efficiency of top dressing urea, ammonium nitrate and ammonium sulphate fertilizers on winter wheat grown on loamy sand and loessial black soil was studied. At a rate of 0.5 g N per pot on the loamy sand 20 % volatilization losses of NH3 occurred with urea and 10 % on the loessial black soil with urea resp. ammonium sulphate.

The grain yields an N removal correspond to these results. At an amount of 1.6 g N per pot the N-uptake of 15N ranged from 0.589 g (urea) on sandy soils to 1.279 g (ammonium nitrate) which agrees with 76 % an 91 % of the total N uptake. On black soil 0.675 g (urea) and 1.038 g (ammonium nitrate) or 44 % and 51 % of the total uptake are found.

Six Sigma is recognized across industries as a standard methodology to systematically improve processes and increase customer satisfaction. In today's competitive business environment, software quality and customer satisfaction are more important than ever. The traditional approach to Six Sigma Software Development is based on analytic models. The analytic models are static, so they do not account for the inherent variability and uncertainty of the software development process, which is an apparent deficiency.

In contrast, this paper presents a Six Sigma approach to Software Development applying simulation. The DMAIC methodology is applied to an ongoing software development sub-process (i. e. test) in order to achieve required (higher) process capability to deliver the project on time, fully meeting the quality requirements. Simulation is used to provide for traditional Six Sigma analysis as well as for considering the uncertain and dynamic factors, which, in comparison with the analytic models, more accurately model the software development process. The DMAIC and simulation experiments are applied on a real IBM™ project, using published data.

Applying simulation to the DMAIC methodology is a significant enhancement. This approach is compliant with CMMI® and provides a strong foundation for performance-driven improvements. The paper demonstrates the practical aspect of the approach.


In the last decades, various researches in the field of robotics have
created numerous opportunities for innovative support of the older population.
The goal of this work was to review and highlight how social robots can help
the daily life of older people, and be useful also as assessment tools. We will
underline the aspects of usability and acceptability of robotic supports in the
psychosocial work with older persons. The actual usability of the system influences the perception of the ease of use only when the user has no or low experience, while expert users' perception is related to their attitude towards the robot. This finding should be more deeply analysed because it may have a strong
influence on the design of future interfaces for elderly-robot interaction. Robots
can play an important role to tackle the societal challenge of the growing older
population. The authors report some recent studies with older users, where it
was demonstrated that the acceptability of robotics during daily life activities,
and also in cognitive evaluation, could be supported by social robots


Christmas is coming up - and most presents around the world will be delivered not by a white-bearded man on a sleigh pulled by reindeer, but by large container ships. Katia Moskvitch looks at the world's largest, the MSC Oscar, which can pack in 19,224 containers.


As a patient on dialysis for the past 25 years, I have often been encouraged to consider using buttonholes for fistula cannulation. Reduced pain, less risk to my fistula, and greater involvement in my dialysis care have all been highlighted as potential advantages. As a patient, I am well aware that many studies report positive outcomes with the buttonhole technique, whereas others warn about an increased risk of infection and questionable benefits to patients.

Although I have not personally experienced buttonhole cannulation, my position is not definitively positive or negative on this practice. Rather, my goal is to illustrate the multiple challenges that patients face in adopting buttonhole cannulation. I am going to approach this topic from my personal perspective after more than two decades in a dialysis chair.

Getting patients to understand why they need dialysis and the types of dialysis modality choices frequently monopolizes the initial conversations. Rarely is the cannulation technique presented as a priority to patients with newly diagnosed ESKD. To the patient going through the stages of grief of losing their kidney function, terms such as "rope ladder" and "buttonhole" have very little meaning. As such, the term "buttonhole" enters into the patient care plan usually well after hemodialysis has been started. …


Online technologies excite the public imagination with narratives of democratization. The Internet is a political medium, borne of democracy, but is it democratizing? This text examines how online digital media shape and are shaped by contemporary democracies.


Accurate glomerular microscopic medical image segmentation is important for renal pathology for obtaining reliable diseases diagnosis. In this study, we construct a pixel-level labeled glomerular microscopic medical image segmentation dataset and improve a classic algorithm, Mask R-CNN, for implementing automatic segmentation of glomerular microscopic medical images. The Improved Mask R-CNN algorithm consists of two parts: in the first part, in order to enhance the accuracy of model training, the anchors in region proposal network are scaled down. In the second part, we increase the number of deconvolution layers in the head mask branch to further improve the glomerular segmentation precision. The experimental results indicate that the algorithm we improve offers higher precision than the original Mask R-CNN algorithm and achieves state-of-the-art segmentation of the glomerular microscopic medical image dataset.


IN 1939 Wegner and I1 and again in 1943 I2 made the statement that "Every discussion of any level of any spinal cord injury should be based on two fundamental concepts. These are that spinal cord injuries are different from spinal column injuries without spinal cord involvement, and that all significant spinal cord injuries are accompanied by spinal shock and its effects." This was on the basis of experience with 101 cervical-cord injuries. Now, sixteen years later and with my experience with such injuries more than tripled, this statement can be reaffirmed without the change of a word. The implications . . .


Previous studies have shown that antibody cross‐linking of the tetraspanin protein CD9 stimulates the degranulation of platelets and eosinophils, although the mechanism of activation is unclear. In this work we transfected human CD9 into the rat basophilic leukaemia (RBL‐2H3) cell line and studied the stimulation of secretion from these cells in response to a panel of anti‐CD9 antibodies. Intact immunoglobulin G1 (IgG1) antibodies activated transfected cells whereas F(ab′)2 fragments of antibody and an intact IgG2a did not. Stimulation of secretion was inhibited by co‐incubation with monomer murine immunoglobulin E (IgE) but not with an IgG1 isotype control, indicating that the response involves the endogenous high‐affinity IgE receptor (FcεRI). The anti‐CD9 antibody activation curve was biphasic, and supraoptimal antibody concentrations stimulated little or no degranulation, indicating that multivalent binding of human CD9 molecules is necessary for the formation of an active complex with rat FcεRI. Immunoprecipitation of FcεRI under mild detergent conditions co‐precipitated CD9, suggesting the presence of pre‐existing complexes of CD9 and FcεRI that could be activated by antibody cross‐linking. These data are further evidence that tetraspanins are involved in FcεRI signalling and may reflect the participation of tetraspanins in the formation of complexes with other membrane proteins that use components of Fc receptors for signal transduction.

Background: Dementia is a rising problem in today's society. Reminiscence therapy is one of the most popular psychosocial therapy methods for people with dementia. A new and innovative method of reminiscence therapy is the method of reminiscence boxes. For this method boxes are filled with objects from the past to trigger dementia patients to get back memories. There is until today no research done with regard to the effect of reminiscence boxes. This research has the purpose to find out in which way the therapy method of reminiscence boxes can be implemented in a specific group of elderly with dementia.
Method: For this research five elderly people with dementia from a specific living group in a health facility, three employees of this facilities and two members of a museum were interviewed. The qualitative analysis of ten interviews is accomplished with a bottom-up analysis. The transcripted interviews are studied and important fragments are selected. The fragments are coded by means of a coding scheme.
Results: The elements from this research which are significant for the intervention can be summed up into four main themes: Enthusiasm and Participation, Concerns and Aims, Implementation Reminiscence Boxes and Arrangement Reminiscene Boxes. The encountered information speaks for the employment of eight theme based boxes in group sessions. Sessions will be lead by the employees of the health facility and will be a fixed part of the monthly schedule.
Conclusion: Trough the results, a valid plan for an intervention at Livio De Meergaarden in 2014 could be established. The encountered results can also be applied at other health facilities in The Netherlands. In further research the practicality of the recommendations made in this rapport can be figured out. Also it must be worked out if these recommendations lead to a successful intervention.


Under anaerobic conditions acetaldehyde added to rat-liver suspensions is metabolized by a coupled oxidation-reduction between aldehyde dehydro- genase (which oxidizes acetaldehyde to acetic acid) and alcohol dehydrogenase (which reduces some of the aldehyde to ethanol). Condensation reactions seem to play no measurable role in this tissue at 0 3 by Lundquist et al. (1959). In all cases where inhibitors were used the effect of these on the analytical methods was examined. Analyses of known amounts of ethanol and acetaldehyde added to the suspensions im- mediately before deproteinization were included as controls in all experiments.


Sweet sorghum extract was used as substrate for lipid accumulation by the oleaginous fungus Mortierella isabellina in batch cultures. Various initial sugar (13–91 g/L) and nitrogen (100–785 mg/L) concentrations resulting in various C/N (43–53) ratios were tested. Oil accumulation ranged between 43% and 51% corresponding to oil production from 2.2 to 9.3 g/L. A detailed mathematical model was developed. This model is able to adequately predict biomass growth, lipid accumulation, and sugar and nitrogen consumption. The model assumes that fungus growth is inhibited at high sugar concentrations. A set of kinetic experiments was used for model kinetic parameters estimation, while another set of experiments was used for model validation. The developed model could be generalized for similar systems of lipid accumulation and become a useful tool for reactor design for biofuel production.

Background: Left ventricular (LV) systolic dysfunction (heart failure [HF] with low ejection fraction [EF]) is regarded as an independent risk factor for poor outcomes after coronary artery bypass grafting (CABG). However, the impact of LV diastolic dysfunction (HF with normal LVEF) still has been unclear. Methods and Results: We identified 1877 patients who received isolated CABG among 15,939 patients undergoing first coronary revascularization enrolled in the CREDO-Kyoto Registry Cohort-2. Among them, 1489 patients had normal LV function (LVEF>50% without a history of HF; Normal group), 236 had LV systolic dysfunction (LVEF≤50% with HF; LVSD group), and 152 had LV diastolic dysfunction (LVEF>50% with HF; LVDD group). Preoperative LVEF in the LVSD group (36±9%) was markedly lower than the Normal (62±12%) and the LVDD groups (61±7%) (p<0.0001). [Table/Figure] In-hospital mortality in the LVDD group was equivalent to the Normal group (1.3% vs. 1.0%, p=0.72). However, cumulative all-cause mortality at 5-yea...


Angelman syndrome is a rare neurogenetic disease caused by the loss of the function of the maternal allele of the UBE3A gene on chromosome 15 (site 15q11.2–q13) and is characterized by severe mental retardation, lack of speech, epilepsy, microcephaly and a characteristic facial phenotype with a unique behavior in the form of frequent laughter. The combination of microcephaly, epilepsy, speechlessness and mental retardation poses a problem for differential diagnosis with many genetic diseases presenting with similar symptoms. Epileptic encephalopathy due to CDKL5 gene mutation and Rett syndrome have the greatest similarity. The hallmark of Angelman syndrome are laughter attacks and specific EEG changes. The authors have presented a table of the differential diagnosis of Angelman syndrome with some phenotypically similar genetic syndromes, indicating the most significant distinguishing features, which should facilitate for the pediatrician and neurologist the diagnostic path of establishing the correct diagnosis.


In this paper, we present a new paradigm that allows dynamically changing the topology of 2-manifold polygonal meshes. Our new paradigm always guarantees topological consistency of polygonal meshes. Based on our paradigm, by simply adding and deleting edges, handles can be created and deleted, holes can be opened or closed, polygonal meshes can be connected or disconnected. These edge insertion and edge deletion operations are highly consistent with subdivision algorithms. In particular, these operations can easily be included into a subdivision modeling system such that the topological changes and subdivision operations can be performed alternatively during model construction. We demonstrate practical examples of topology changes based on this new paradigmand, and show that the new paradigm is convenient, effective, efficient, and friendly to subdivision surfaces.


The state guarantees sufficient food for every citizen as regulated in the 1945 Constitution of the Republic of Indonesia. Food availability is highly dependent on the existence of sustainable food agricultural lands. The conversion is the cause of food agricultural land decrease. Unmet food needs will then affect national food security. The problem in this research is the effect of granting permits for the conversion of productive agricultural land into residential land and its relation to food security in Indonesia. This legal research uses a normative juridical approach. Data was collected through a literature review and analyzed qualitatively. The results show that agricultural land is decreasing every year due to its conversion into residential and infrastructural lands for the public interest. In the end, with insufficient food needs, national food security is diminished. In conclusion, permits to convert sustainable food agricultural lands should only be given on the condition. The recommendation of this research is for the regional government, the Ministry of Agrarian and Spatial Planning/National Land Agency (ASP/NLA), and Notary/Land Deed Official to work collaboratively in providing information on the impact of agricultural land conversion on the sustainability of food availability.

We study the determination of γ from CP-violating observables in B → ππ and B → ψKS. This determination requires theoretical input to one combination of hadronic parameters. We show that a mild assumption about this quantity may allow bounds to be placed on γ, but we stress the pernicious effects that an eightfold discrete ambiguity has on such an analysis. The bounds are discussed as a function of the direct (C) and interference (S) CP-violating observables obtained from time-dependent B → ππ decays, and their behavior in the presence of new physics effects in B −B mixing is studied.


In locomotive operation system, video monitoring system is the most critical. It is responsible for collection, processing and storage of data during operation of locomotive, to ensure safety of locomotive running. Traditional locomotive monitoring management approach has complex operation, but also lacks the intuitive and real-time for locomotive management personnel, which will bring some potential risks for drivers driving. So this paper, based on this situation, designs a new locomotive video monitoring system, adopting data collection, compression, driver-assist, wireless telecommunications and other technologies, to completely enhance the locomotive security monitoring efficiency from vehicle terminal to monitoring terminal.
