Purpose

Using Shanghai as an example, the purpose of this paper is to perform grade evaluation and zoning for different land use spaces by GIS by identifying the major restrictive factors in current socio-economic development.

Design/methodology/approach

Based on short plate theory, 11 major restrictive indicators that will restrict socio-economic development in Shanghai are identified, and urban land is divided into four subspaces and the restrictive grade evaluation of urban land subspace is achieved with GIS spatial analysis; then, land development zoning is processed according to the results of the evaluation.

Findings

In all, 11 major restrictive indicators that will restrict socio-economic development in Shanghai are identified. The restrictive grades of the agricultural production, urban construction and ecological protection subspaces are mainly common, weak and weaker, and the relatively strong restrictive grade of industrial development subspace is mainly concentrated in the more developed industrial districts (counties). The areas of the common and good regions of constructive development and ecological development zones account for 87.4 and 98.3 per cent of each total area, respectively, and urban land still has significant development potential in Shanghai.

Originality/value

This paper proposes various urban land space evaluations and zoning strategies based on restrictive indicators and perspectives, enriching the ideas and methods of urban land use evaluation.


Open source software adoption in enterprise computing is growing but this does not mean that it is suitable for every enterprise. ET and in even a medium-sized organisations the volume discounts and site licences that are available from software vendors bring the purchase price of commercial software down significantly from the official list-price. The physical cost of providing a software product to an organisation is no more than a few pounds for a manual and a CD, which means that the vendor of commercial software can discount as far as they wish (or, more accurately, feel necessary) in order to secure a sale. It's also common to offer discounts to get a foot in the door; once a vendor has persuaded a client to adopt its product, the cost and effort of moving away either to a competitor product or an open source rival can far outweigh the benefits of adopting that alternative product.


According to the experimental research on the short-limb shear wall subjected to cyclic loading, the effect of flange width/thickness ratio and ratio of stiffness on the energy dissipation and ductility have been analyzed. Finally, some suggestions for engineering design are also presented in this paper.


The proton‐induced direct reactions like elastic, quasi‐elastic scattering and knock‐out at intermediate energies and inverse kinematics are the most powerful classical methods for obtaining spectroscopic information on the structure of unstable exotic nuclei. Few elastic scattering experiments performed at GSI with the gaseous and liquid hydrogen targets provided the most precise data on a nuclear matter distribution and a halo‐core structure of the neutron‐rich He and Li isotopes. The measured differential cross sections have been also used for probing density distributions as predicted by various microscopic theories. The comparison of the data with the latest calculations will be shown. The description of the recent experiment with proton‐rich 8B and neutron‐rich Be isotopes is presented.The experimental conditions at the future facility FAIR will provide unique opportunities for nuclear structure studies on nuclei far off stability, and will allow to reach new regions in the chart of nuclides of high...


Objective Cervical cancer (CC) is one of the main causes of death among gynecological malignancies. Patients with CC with lymph node metastasis (LNM) have poor prognoses. We investigated the risk factors and prognosis of LNM in patients with CC patients using data from the SEER database. Methods We collected the information of cervical cancer patients registered in SEER database from 2010 to 2015. The dataset was divided into a training set and a validation set at a 7:3 ratio. LASSO regression analysis was used to evaluate risk factors for LNM in patients with CC. Using the results, we established a nomogram prediction model. C-index, ROC curves, calibration curves, decision curve analysis, and clinical impact curves were used to evaluate the prediction performance of the model. Results We included 14,356 patients with CC in the analysis. Among these, 3997 patients were diagnosed with LNM. A training set (10,050 cases) and a validation set (4306 cases) were used for the following analysis. We established nomogram LNM prediction models for the patients with T1-2-stage CC. The C-indices for the internal and external validations of the prediction models were 0.758 and 0.744, respectively. In addition, we established a prognostic nomogram for all CC patients with LNM, and the internal and external validation C-indices were 0.763 and 0.737. Conclusion We constructed a quantitative and visual predictive nomogram that predicted prognosis of patients with LNM in CC to provide clinicians with a reference for diagnosis and treatment.


In order to analyze the control strategy of the low voltage ride through (LVRT) of DFIG during the asymmetric voltage sag, it is necessary to analyze the transient performance of a DFIG during the asymmetric voltage sag. In this paper, analyzed the influence of the asymmetric grid voltage to DFIG and the analysis method of the asymmetric voltage sag, and on the basis of positive and negative sequence mathematical model, analyzed the composition of stator output active and reactive power under the condition of asymmetric grid voltage. And built a DFIG asymmetric voltage drop simulation model of 1.5MW in MATLAB/Simulink, the simulation results shows that the stator voltage, current, active power and reactive power all present a double frequency ripple during the asymmetric voltage sag, consistent with theoretical analysis. It can provide theoretical basis for double-fed motor control strategy of asymmetric LVRT.


Gasoline demand, which represents almost a quarter of world petroleum consumption, has been the focus of a considerable amount of econometric work since the 1973 oil embargo. However, researchers and policymakers when considering this work are confronted with a bewildering array of elasticities and results that come from a variety of data sets and model types. This survey stratifies these elasticities for statistical analysis and development of summary elasticities, identifies basic issues, and illustrates a strategy for summarizing studies that should be useful to policymakers and researchers in any area of applied work. Because space prohibits discussing all of this work, this survey is limited to those studies that have estimates for gasoline demand, vehicle miles traveled, and miles per gallon.


Sparse WMNs can support a significant extent of communication. This is specially true in the presence of mobility coupled with asynchronous communication. However, existing tools may not be sufficient for exploring the design of such networks. We presented a metric, reachability, its empirical characterization, and two tools for aiding the design of sparse WMNs. A detailed account of their use in facilitating tradeoffs for sparse WMN deployment can be found.


The paper analyses the scientific contribution of professor dr dr h.c. Vladimir V. Vodinelic to date and singles out the novelties he introduces to domestic theory of civil law in his works, and particularly in his latest textbook Civil Law: An Introduction to Civil Law and the General Part of Civil Law (2012). The paper focuses on the designed and applied systematics of civil law, giving special attention to the differentiation between the introduction to civil law and the general part of civil law. After a comparison with the concept, contents and systematics applied in other recent civil law textbooks, the conclusion is that this textbook is the most comprehensive, most complete and the most extensive one, and also seems to include most examples. It differs from other textbooks, inter alia, by in fact including two textbooks in one, thus allowing the student to identify the application of civil law norms to every-day situations, while at the same time explaining the functions of the institutes and the practical legal significance of the divisions. In addition to considering the genesis of this professor Vodinelic's work, by identifying three central steps that can be detected after analyzing his legal opus so far, special attention is given to the analysis of the didactic contribution of this renown civil lawyer and the methods he uses to make civil law matters more approachable to students.


While Web 2.0 tools are increasingly being adopted by academic libraries to connect with patrons, they are not actively used to facilitate knowledge management (KM). This study investigates the awareness and comfort of librarians, their perceived usefulness of KM using Web 2.0, organizational readiness, and the ways in which these affect the library adoption of KM using Web 2.0. The survey questionnaire was completed by 101 librarians from 35 countries in 6 continents. Most respondents had heard of KM, were comfortable with Web 2.0, perceived KM using Web 2.0 to be highly useful, but were not entirely sure if their libraries were ready to adopt KM. Comfort with Web 2.0 was found to impact perceived usefulness, which in turn, strongly affected the likelihood of adoption of KM using Web 2.0. This is the first study that combines KM using Web 2.0 from the perspective of academic librarians globally, and has important implications for theory and practice.


Assuming a known (constant) current distribution on the thin circular loop antenna of arbitrary radius in free space, an exact integration of the vector potential is performed without recourse to approximations. The only restrictions on the solution variables are that the observation point distance must be greater than the loop radius and that the polar angle must run between 0 and /spl pi/. The resulting vector potential infinite series solution possesses a real part composed of linear combinations of complete elliptic integrals of the first and second kind and an imaginary part composed of elementary functions. Thus, it is possible to obtain an exact solution which is valid everywhere that r>a and 0/spl les//spl theta//spl les//spl pi/. The electromagnetic field components of the constant current circular loop antenna are then determined by direct series differentiation. These solutions are valid in the near and induction fields, converging rapidly there, and are also valid in the far field, although many terms of the series are needed for convergence.


This paper presents the development and integration of an X-configuration quadcopter with an IP camera for object detection based on the color of an object. A KK2 microcontroller is used to control the quadcopter movements. The controller has built-in gyros that provide heading rate information, which are used to control the movement of the quadcopter. The parts of the whole UAV are selected and integrated. The calibration processes are handled after installing necessary controller codes. This is to make quadcopter fly smoothly according to its set commands. The IP camera is then attached to the quadcopter frame. Mobile camera with GPS receiver is used for object detection and localization. Images are captured from the IP camera; the three-dimensional position information for the quadcopter is recorded by the GPS receiver, and then the whole data are sent repeatedly from the Mobile to a ground station computer via wireless communication link. Two algorithms are next implemented to acquire and analyze the Images received form the IP camera. The results show that the images was captured and analyzed successfully, and the objects were detected according to their color and its approximate position was reported.


The classical Onofri inequality in the two-dimensional sphere assumes a natural form in the plane when transformed via stereographic projection. We establish an optimal version of a generalization of this inequality in the d-dimensional Euclidean space for any d≥2, by considering the endpoint of a family of optimal Gagliardo-Nirenberg interpolation inequalities. Unlike the two-dimensional case, this extension involves a rather unexpected Sobolev-Orlicz norm, as well as a probability measure no longer related to stereographic projection.


A detailed investigation has been carried out into the evolution of grain size and grain orientation in electroplated Cu interconnection lines. The specimens were annealed to produce a range of different grain size distributions. Very accurate grain size distributions were obtained from extensive TEM observations of a large number of specimens, followed by computer tracing of grain boundaries. Although annealing causes the average grain size to increase, very small grains are found to persist in the distribution, even when the average grain size is large. These small grains have been investigated in detail to determine the reason for their thermal stability. In addition, the occurrence and redistribution of small micro-voids has been investigated for wafers with different grain sizes. These voids are believed to be associated with seams which are formed in the Cu lines during plating.


In cases of vitreoretinal interface diseases, such as macular hole or macular pucker, the inner limiting membrane (ILM) or epiretinal membranes (ERM) need to be surgically removed. The challenging step in the surgery is the transparency of ILM and ERM that makes the membranes difficult to identify and to peel without risk of damaging the retina. Only a few vital dyes have been proposed to stain the ILM and ERM and no perfect dye is available that would stain the tissue of interest sufficiently, while being non-toxic and stable in aqueous solution. During cataract surgery a dye to stain outer part of a capsule of the lens is used when the red reflex from the fundus is absent. Dyes used for capsulorhexis need to be safe for corneal endothelial cells. Phototoxicity needs to be tested for dyes intended to be used in vitreoretinal surgery. A very strong source of light is present during the surgery, that can cause the dyes to become toxic while illuminated. A set-up for testing phototoxicity on a 96-well plate has been developed. New models for staining ability of dyes for ILM and ERM are suggested, as porcine eye was proved not reliable for those studies. Instead, a model for ILM and ERM was developed with good correlation to staining of human ILM and human ERM. Pig eyes can, however, serve as a useful model for capsule staining when cataract is induced in them.
A new dye for capsulorhexis is presented. No safe, green dye that would stain the capsule had been suggested before. The new dye is an alternative to the currently used Trypan Blue and provides as strong staining while being slightly less toxic to corneal endothelial cells.
Fourteen new dyes, that belong to the cyanine family, were synthesized and investigated for staining ability, toxicity, and stability in aqueous solution. Two of the new substances were found to stain the model for ILM in green, while being safe to retinal epithelial cells. Their stability in aqueous solution can be achieved with additives.


: Existing theories of thermal comfort are largely blind to the way heat is delivered to spaces. Field studies, however, show that people create and enjoy thermal conditions that lie outside conventional definitions of comfort—the thermal experience itself is valued—some of which are tied to particular ways of delivering heat. The concept "exergy" can be used to describe the quality of heat energy and its ability to provide warmth. A shift from fossil fuels towards renewable sources heralds a new era of space heating consisting mainly of low exergy sources, such as heat pumps. This marks a major turning point in the history of domestic heating. This paper begins by discussing variations in domestic thermal environments before considering new forms of low carbon heating. Later sections analyse the way in which these systems deliver heat within people's homes and consider the implications for thermal experience, comfort and energy consumption.


Abstract : Underwater acoustic sensors are subject to interfering ambient noise generated by the action of wind on the sea surface. Noise at frequencies above a few hundred Hz generally shows strong correlation with wind speed. A knowledge of the statistical variability of wind-speed is useful for predicting the properties of ambient noise. Values of surface wind speed and atmospheric pressure reported from weather stations at Jan Mayen in the Norwegian Sea and Bear Island in the Barents Sea over a two-year period were examined. It was found that the statistical distribution of wind speeds can be represented approximately as a Rayleigh distribution. Spectral analysis of the time series records of wind speed and pressure shows that most of the variability of these parameters is contributed by synoptic scale variations having periods of from a few days to a few weeks. The annual or seasonal variations has the largest signle Fourier coefficient but represents only a relatively small part of the total variance. (Author)


INTRODUCTION
Cerebral blood flow during exercise is impaired in heart failure patients implanted with left ventricular assist devices (LVADs). Our aim was to determine whether a 3-month exercise training program could mitigate cerebrovascular dysfunction.

METHODS
Internal carotid artery [ICA] blood flow, intra-cranial middle [MCAv] and posterior cerebral [PCAv] artery velocities were measured continuously using Doppler ultrasound, alongside cardiorespiratory measures at rest and in response to an incremental cycle ergometer exercise protocol in 11 LVAD participants (5♀, 53.6±11.8 yrs; 84.2±15.7 kg; 1.73±0.08) pre (PreTR) and post (PostTR) completion of a 3-month supervised exercise rehabilitation program.

RESULTS
At rest, only PCAv was different PostTR (38.1±10.4 cm.s-1) compared to PreTR (43.0±10.8 cm.s-1; p<0.05). PreTR, the reduction in PCAv observed from rest to exercise (5.2±1.8%) was mitigated PostTR (p<0.001). Similarly, exercise training enhanced ICA flow during submaximal exercise (~8.6±13.7%), resulting in increased ICA flow PostTR compared to a reduced flow PreTR (p<0.001). Although both PETCO2 and MAP responses during incremental exercise were greater PostTR than PreTR, only the improved PETCO2 was related to the improved ICA flow (R2=0.14; p<0.05).

CONCLUSION
Our findings suggest that short-term exercise training improves cerebrovascular function during exercise in patients with LVADs. This finding should encourage future studies investigating long-term exercise training and cerebral and peripheral vascular adaptation.


A decade ago the Court approved limited use of race-conscious remediation. Since then, the concept of affirmative action has operated on tenuous constitutional footing subject to claims that preferences victimize their intended beneficiaries and innocent persons and may create limitless preserves.


Under the influence of global climate change and Arctic warming,Arctic issues have gradually become the focus of international politics and economics.Logically,China's Arctic identity determines her interests,and its key character is economic interests.The identities of both non-Arctic state and near-Arctic state cannot meet the need of China's economic goals.By contrast,the stakeholder,as China's Arctic identity,is of practical value and plasticity to some degree.There is gap of response between China's diplomatic model of "strong bilateral diplomacy plus weak multilateral diplomacy" and Arctic issues.Therefore,to optimize China's Arctic identities from different facets could be a useful path to realize Arctic economic goal as well as the harmonious Arctic which is the ultimate goal of China's Arctic diplomacy.


Digits experiments For SV HN → MNIST experiment, we used DigF1, DigC1, DigG and DigD architectures mentioned in Fig. 1 as our F ,C,G andD networks respectively. For all other digit experiments, we use DigF2, DigC2, DigG and DigD. All models were trained from scratch and were initialized using random Gaussian noise with standard deviation 0.01. We used Adam solver with base learning rate of 0.0005 and momentum 0.8 to train our models. The cost coefficients α and β are set as 0.1 and 0.03 respectively based on validation splits. We resize all input images to 32 × 32 and scale their values to the range [0, 1].


Posaconazole is a new triazole drug with broad-spectrum activity in vitro against most yeasts and molds such as candidae,cryptococcus neoformans,aspergillus,Fusarium and zygomycetes,and also against certain species of dimorphic fungi and endemic fungi.In immunocompetent or immunocompromised animal models of invasive fungal infections,Posaconazole has been demonstrated to provide highly-effective,broad-spectrum antifungal activities.In-vitro and in-vivo activities of posaconazole were superior to those of other azoles against Candida glabrata,Candida krusei,Aspergillus terrus,fusarium and zygomycetes.In vivo sensitivity studies have shown the promising efficacy of posaconazole against life-threatening fungal infections in animal models with different immune status and sites of infections.


Abstract. Following 30 years of research, it is common sense that crushed salt is the most suitable geotechnical material for encapsulating radioactive waste in a rock salt repository (e.g., Chaikowski et al., 2020). After emplacement, it provides sufficient permeability to allow outflow of unwanted canister-corrosion gases. In the long term, however, when it becomes compacted by converging cavity walls, it safely hinders any fluid flow from and to the waste. Hence, it is essential to know the evolution of (1) the material's key parameters during compaction, such as porosity and permeability, backfill resistance and viscosity; (2) the material's response to environmental controls, such as temperature, humidity, and stress; and (3) the material's long-term rheology. Here we align microstructural deformation indicators with physical processes that underlie compaction (Mills et al., 2018a). We strive to identify and – where feasible – to quantify the dominant deformation mechanisms (Blenkinsop, 2002; Jackson and Hudec, 2017). As a preliminary result, we show that the abundancy of deformation indicators increases with increasing compaction state. In early compaction, we observe more brittle mechanisms, such as grain fracturing (Fig. 1a) and cataclastic flow. At later stages, especially in the presence of moisture, plastic deformation overtakes. Therein, we observe an increased presence of indicators for pressure solution precipitation (grain boundary seams) and dislocation creep (subgrain formation, Fig. 1b), with progressing deformation. In our upcoming work, we aim at linking the observed indicators to environmental controls, such as moisture content, temperature, and strain rate by applying our approach to larger suits of samples compacted under best-known controlled conditions. Final goal is the joint interpretation with findings from in situ-compacted material (Mills et al., 2018b). Do lab tests mimic in situ processes of crushed salt compaction adequately? Can we learn how to do better by means of microstructural investigations?


In a multimedia framework, digital image sequences (videos) are by far the most demanding as far as storage, search, browsing and retrieval requirements are concerned. In order to reduce the computational burden associated to video browsing and retrieval, a video sequence is usually decomposed into several scenes (shots) and each of them is characterized by means of some key frames. The proper selection of these key frames, i.e. the most representative frames in the scene, is of paramount importance for computational efficiency. In this contribution a novel key frame extraction technique based on the wavelet analysis is presented. Experimental results show the capability of the proposed algorithm to select key frames properly summarizing the shot.


Acetaldehyde is one of the most important flavor ingredients in beer.Excess acetaldehyde produces a grassy or apple-like off-flavor.One target of beer production is to produce the beer with low acetaldehyde content.It was summarized about the properties of acetaldehyde,the metabolism of acetaldehyde in Saccharomyces cerevisiae during fermentation and aging,the factors impacting acetaldehyde content in beer,and some research progress on acetaldehyde content control.


As a top-10 gold mining countries, Indonesia becomes the most attractive investors destination in mining sector. Those foreign investors shall be a Joint Venture Company with a domestic company. That joint venture company later must be making an agreement with Indonesia's government in form contract of work. Conflict of interests are often happen within holding companies with joint venture company's measure performing contract of work. In this case discussed in this writing, the holding companies are making an agreement of which the object of that agreement turns out being an object which is must be executed based on the case verdict between the joint venture company and the government of Indonesia. The losingparty may apply for agreement revocation or derdenverzet over the verdict.

Cultured eggs of Cyathocephalus truncatus were found to develop optimally at 20°C, but they did not develop at 6°C and above. The oncosphere of the tapeworm has been seen to be a true hexacanth embryo. Specimens of the intermediate host. Gammaurs pulex, were infected by being forced to feed on pieces of lettuce leaves on which infective eggs of the tapeworm were placed. The young drveloping porocercoid was first recovered from the haemocoel of Gammarus pulex 5 days after infection. The procercoid was found to reach the infective stage within the amphipod after about ten weeks.


An increase in birth rates to Minneapolis minors following the enactment of a parental notification law was examined. A well-publicized link between increasing birth rates and the law is shown to have been premature. Birth, abortion, and population data by age, race, and region suggest that the increasing birth rate in Minneapolis was not related to parental notification, but rather to a growing racial minority population.


The plane problem of two‐dimensional decagonal quasicrystals with a rigid circular arc inclusion was investigated under infinite tension and concentrated force. Based on complex representations of stresses and displacements of two‐dimensional decagonal quasicrystals, the above problem is transformed into Riemann boundary problem by using the analytic continuation principle of complex functions. The general solutions of two‐dimensional decagonal quasicrystals under the action of plane concentrated force and infinite uniform tension are derived. The closed solutions of complex potential functions in several typical cases are obtained, and the formula of singular stress field at the tip of rigid line inclusions is given. The results show that the stress field at the tip of circular arc rigid line inclusions has singularity of oscillation under plane load. Numerical examples are given to analyze the effects of inclusion radius, different inclusions, the coupling coefficient and phason field parameter on stress singularity coefficients.


BACKGROUND: Freeze-dried bone has strong immunogenicity due to insufficient removal of xenoantigen. Deproteinized bone and completely-decalcified bone have weak antigenicity, but the former has no osteoinductive property, and the latter has poor biomechanical property, so both of tem are limited in clinical application.
OBJECTIVE: To observe the change of rabbit peripheral blood T lymphocyte subsets after transplantation of tissue engineered bone constituted by partially-decalcified freeze-dried bone scaffold and the histological changes of transplanted tissue.
DESIGN, TIME AND SETTING: Randomized grouping, controlled animal observation, performed in the State Key Laboratory of Biotherapy (i.e. Department of Stem cells and Tissue Engineering), Huaxi Hospital, Sichuan University between June 2006 and June 2007.
MATERIALS: Tissue-engineered bone was in vitro constructed using osteoblasts, which were derived from rabbit periosteum and used as seeding cells, and xenogeneic cancellous bone, which were antigen self-digested, partially-decalcified freeze-dried bone.
METHODS: Forty-eight rabbits were randomly divided into the following 4 groups, with 12 rabbits in each group: partially-decalcified freeze-dried bone group (partially-decalcified bone group), tissue engineered bone group, autogenous bone group, and allogeneic bone group. Partially-decalcified freeze-dried bone, tissue engineered bone, autogenous bone, and allogeneic bone were respectively implanted into the 1 cm segmental defect in rabbit radius in above-mentioned groups.
MAIN OUTCOME MEASURES: Prior to and 1, 2, and 4 weeks after implantation, the change of rabbit peripheral blood T lymphocyte subsets were examined by flow cytometry; At 2, 4, 8, and 12 weeks after implantation, osteogenesis of the 4 materials was examined by routine histological examination.
RESULTS: ① In the partially-decalcified bone group, peripheral blood CD4(superscript +) and CD8(superscript +)T lymphocytes were significantly increased at 1 and 2 weeks after implantation than prior to implantation (P<0.05). At 4 weeks after implantation, CD4(superscript +)T lymphocytes were increased, but not significantly, compared with prior to implantation (P>0.05). In the autogenous bone group, CD4(superscript +) and CD8(superscript +)T lymphocytes were increased, but not significantly (P>0.05). In the allogeneic bone group, CD4(superscript +) and CD8(superscript +)T lymphocytes were significantly increased at weeks 1, 2, and 4 after implantation than prior to implantation and the synchronic phase in the other groups (P<0.05). ② In the tissue engineered bone group, at week 2 after implantation, osteoblasts and chondroblasts were visible in the material porous, in addition, a new mixed tissue containing bone and cartilage formed and surrounded by osteoclasts, and partial rack was destroyed and absorbed. At week 4, newly formed bone had turned into woven bone. At week 8, lamellar bone was found, and partially-decalcified freeze-dried bone was completely degraded and absorbed. At week 12, the implant had been completely substituted by lamellar bone, and medullary cavity was recanalized.
CONCLUSION: Tissue-engineered bone constituted by taking partially-decalcified freeze-dried bone as scaffold led to an increase in peripheral blood T lymphocytes, but which did not influence its good repair capability of bone defects. implanted into the animal models of bone defects to identify the osteogenic potential of bio-derived bone, detect related immunological indices, and evaluate the feasibility of the bio-derived bone used as scaffold material.

The expansion of the velocity distribution function for the homogeneous cooling state (HCS) in a Sonine polynomial series around a Maxwellian is shown to be divergent, though Borel resummable. A convergent expansion for the HCS has been devised and employed to obtain the HCS velocity distribution function and (using it) the linear transport coefficients for a three dimensional monodisperse granular gas of smooth inelastic spheres, for all physical values of the coefficient of normal restitution. The results are in very good agreement with findings of DSMC simulations.


Several mechanisms may influence recovery and act as a complementary intervention to regenerative medicine. One area of consideration that may improve clinical outcomes in patients receiving regenerative medicine treatments is the utilization of supplementary interventions referred to as regenerative rehabilitation. One such intervention may be the use of light therapy also known as photobiomodulation (PBM). Terms synonymous with PBM include low-level light therapy (LLLT), low-power laser irradiation or cold laser. As a musculoskeletal intervention, PBM is administered via a mechanism that creates light through optical amplification. These interventions describe a form of PBM or light therapy that uses specific param-eters to target tissues through direct or indirect contact with or without heat or structural tissue alterations. PBM may improve treatment outcomes based on synergistic effects that are thought to modulate inflammation and facilitate cellular repair. This manuscript provides an overview of the current evidence supporting the use of PBM as a complementary intervention to regenerative medicine with a focus on managing conditions related to the musculoskeletal system.


An important problem arising in the management of logistic networks is the following: given a set of activities to be performed, each requiring a set of resources, select the optimal set of resources compatible with the system capacity constraints. This problem is called Batch Selection Problem (BSP) from traditional applications to flexible manufacturing. BSP is known to be NP‐hard, and is also considered a difficult integer programming problem. In fact, polyhedral approaches to BSP suffer from the poor quality of the bound provided by the linear relaxation, even after strengthening. We devise an implicit enumeration scheme that attempts to overcome this difficulty. It is based on a formulation of BSP, which is equivalent to a stable set problem with one side constraint. This allows to exploit the upper bound, not only for pruning subproblems, but also for controlling the number and the quality of the subproblems generated. We show the effectiveness of the approach by an extensive computational experience on real‐sized randomly generated instances. © 2004 Wiley Periodicals, Inc. NETWORKS, Vol. 44(2), 151–159 2004


An erosion-suppresisng deep enzymolyzing process for low-value fish features that said low-value fish is enzymolyzed by endoproteinase and exoproteinase under 0.1-0.3 MPa while filling clean air or O2 to kill or suppress the anaerobic bacteria.


Function-as-a-Service has been notoriously difficult to compose and integrate, leaving developers to resort to third-party datastores and queues as means to share state between functions. Applying this architecture on a geo-replicated setting may produce inconsistent application states due to replication delays and weak consistency guarantees, thereby resulting in inconsistent function outputs and ultimately a bad end-user experience. Rendezvous is a framework that automatically ensures consistency of data in serverless applications using datastores, and guarantees that no stale values are read.


I am a Colombian family doctor and a clinical epidemiologist. Four months ago I left my country and migrated to the United Kingdom. This is my experience of what it is like to be part of the so called "brain drain" of doctors from developing countries to rich countries in the north.

As a researcher in Colombia I was based in a private university and supported by one of the international clinical epidemiology network's units. My work was well valued and as a group we were able to sort out many of the difficulties that researchers have to solve, such as finding funding while the American government imposed sanctions as part of its drug fighting policies. We were able to …


The purpose of this project is to develop the measurement instrument of cutting force for turning tool post using strain gauge and Arduino. The forces developed when the tools are in contact with the work pieces are captured and transformed into the numerical form system. The captured cutting force signal were then amplified, undergo signal conditioning and converted to digital signals to be read by Arduino. After calibration tests on the x and y directions, with calculations, the corresponding force readings are obtained and displayed for real time monitoring. The results obtained proved its reliability and effectiveness for measuring cutting forces and displayed on a PC for monitoring purposes.


Members of the public are often left choosing between two extreme candidates who will not represent the moderate, aggregate, public effectively. Cross-pressured members of the U.S. Congress serve a constituency that votes for the opposite party at the national level. If there is any group of representatives that have an incentive to moderate their voting behavior, it is cross-pressured members. In this article, I show that cross-pressured members are more moderate than the average member of their party. This could provide constraints on rampant partisanship in the form of districts that are comfortable electing a representative of one party and voting for the president of the other. However, I show that these members are significantly less likely to be reelected. Thus a paradox exists in which cross-pressured members who moderate their voting behavior are no more likely to be rewarded for behaving the way citizens claim they want to represent.

The linearity and efficiency of microwave amplifiers were improved by operating the active devices in a linearised class-B mode. Good linearity, i.e., low intermodulation distortion, derives from a cancellation effect of the intermodulation products. At the same time, high efficiency is obtained because of operation in class B. Special active bias circuits were designed to extend the maximum modulation bandwidth of the amplifiers. Under low intermodulation conditions, the output power and efficiency were improved five to six times over those of amplifiers operating in class A. Moreover, the maximum modulation rate was extended to 100 MHz. These high-efficiency, high-power amplifiers are well suited for telecommunication satellite transponders.

In this work we discuss the strength of the trilinear Higgs boson coupling in composite models in a model independent way. The coupling is determined as a function of a very general ansatz for the fermionic self-energy, and turns out to be equal or smaller than the one of the Standard Model Higgs boson depending on the dynamics of the theory.


This article presents an approach to obsessive-compulsive disorder based on the Gestalt therapy theory, Gestalt psychology and psychiatric phenomenology. After establishing a diagnostic framework, the experiences of patients are explored, starting from the experience of space and time, of the relationship between details and the whole, of boundaries, and of materiality. In the light of the Gestalt theory of perception, the obsessive-compulsive symptom is framed as a creative adjustment protecting the patient from more severe suffering in a situation in which the bodily sensorial ground is permeated with terror. After describing how the obsessive-compulsive field is aesthetically actualized in therapy, a number of issues are highlighted that can help therapists in their journey with the sufferers.


ABSTRACT
 This article raises concern about the growing embrace of "eco-survivalism"—an environmental discourse motivated by the idea of "riding out" what is seen as the inevitable collapse of the global economy and human population caused by severe environmental degradation. First, we identify this environmental discourse and differentiate it from other leading contemporary environmental discourses which are primarily motivated by the challenge of averting collapse. Second, we show how the rise and spread of eco-survivalism today is catalyzed by the growing perceived urgency of the global environmental crisis as conditioned by neoliberal capitalism. Finally, we consider some of the concerning implications of its rise, including the emergence of environmental defeatism, the depoliticization of environmental action, and the reification of socio-economic injustices (in terms of who is deemed worthy of "surviving").


We experimentally demonstrate a 4-stage and an 8-stage Ge/Si distributed traveling-wave photodetectors (TWPDs) with high RF output powers and large bandwidths. The genetic algorithm is utilized to synergistically optimize multiple relevant design parameters, including the dimension of the coplanar waveguide electrode and the aperiodic arrangement of the PD array. After the genetic algorithm optimization, the 3dB bandwidth of the 4-stage TWPD is improved from 46 GHz to 54 GHz under the constraint that the bandwidth of the unterminated single PD element is 50 GHz. Meanwhile, the 3dB bandwidth of the 8-stage TWPD is improved from 33 GHz to 40 GHz. A good agreement between measured and calculated frequency responses is obtained. The measured maximum RF output powers of the aperiodic 4-stage and 8-stage TWPDs at 30 GHz are 2.5 dBm and 6.3 dBm, respectively. Furthermore, the effectiveness of our design methodology is verified by measurement results of devices fabricated at different silicon photonics foundries.


Objective:To research the effect of 17-β-estradiol allying with HMGB1 overexpression on the cell cycle and NF-κB signal pathway of human monocytes lines THP1 cells.Methods:The HMGB-1 expression vector was transfected into THP1 cells after cell cycle synchronization by serum starvation;Synchronized THP1 cells were stimulated by 10-9 mol/L 17-β-estradiol for 16 h and 30 h,the cell cycle phase distribution was analyzed by flow cytometry,and the mRNA expression level of Cyclin A and Cyclin D1 were analyzed by RT-qPCR,and the expression level of HMGB-1 protein was analyzed by western blot,and the activity of NF-κB was analyzed by luciferase reporter gene.Results:The HMGB1 protein level in the transfected cells increased 3.7-fold compared to the normal THP1 cells,and THP1 cells were synchronized by serum starvation successfully and the proportion of cells in the G1 phase increases from 53% to 78% after synchronization;After HMGB1 overexpression cells stimulated by 17-β-estradiol for 30h,mRNA level of Cyclin A increased 7.9-fold compared to the control group while Cyclin D1 mRNA level decreased by 41%,as well as the proportion of cells in the G1 phase decreased from 53.11% to 33.33% and that in the S phase increased from 35.43% to 53.91%,and this difference arrived to the maximum at 30h after stimulation;The activity of NFκB in HMGB1 overexpressed cells increased obviously after stimulated by estrogen,and this effection is ahead of the change of cell cycle kinetics.Conclusion:The regulation of estrogen to THP1 cell cycle is dependent on HMGB1,and NF-κB appears to be involved in this procedure.


When studying the particle energy spectra, particles with different energies are counted within the respective energy intervals. Also, in this case counting is performed during long time intervals so that large enough count numbers are obtained. A considerable fraction of temporal variations and thus the important information contained in them will be lost. For example, the variance pattern contains information about subpopulations present in the data. In order to preserve the information about the covariance of different spectral channels, high counting rates must be guaranteed by detector characteristics and not by long measuring intervals. In the present report a linear decomposition technique using the principal components is used to separate the subpopulations of particles present in the data. The described method will be applied to particle energy spectra measured onboard the Swedish satellite Viking (Hultqvist 1988).


The design, construction and testing of a humidity management system for airborne ultrafine particle field measurements is described. The system was designed to allow modification of commercially available ultrafine particle counters and sizers deployed on the UK particle counting and sizing network such that they meet the recommendations of the academic group EUSAAR, whilst supporting the other objectives defined by Defra.


Based on the background of the rapid development of the digital economy, panel data of China's A-share listed companies from 2014 to 2021 are selected to explore the impact of digital transformation on enterprise performance and the logical relationship between digital transformation, enterprise performance and ESG. The results show that enterprise digital transformation can improve enterprise performance, and ESG performance plays an intermediary role in the improvement path of enterprise digital transformation to enterprise performance. Further, the results are still valid after Sobel and Bootstrap tests, variable substitution and time lag method. The conclusion of this study provides a theoretical basis for clarifying the influence path of enterprise digital transformation on enterprise performance, improving enterprise ESG performance, and promoting high-quality economic development.

Purpose: Today's state-of-the-art CT systems rely on a rotating gantry to acquire projections spanning up to 360 degrees around the head and/or body. By replacing the rotating source and detector with a stationary array of x-ray sources and line detectors, a head CT scanner could be potentially constructed with a small footprint and fast scanning speed. The purpose of this project is to design and construct a stationary head CT (s-HCT) scanner capable of diagnosis of stroke and head trauma patients in limited resource areas such as forward operating bases. Here we present preliminary imaging results which demonstrate the feasibility of such a system using carbon nanotube (CNT) x-ray source arrays. Methods: The feasibility study was performed using a benchtop setup consisting of an x-ray source array with 45 distributed focal spots, each operating at 120kVp, and an Electronic Control System (ECS) for high speed control of the x-ray output from individual focal spots. The projection data was collected by an array of detectors configured specifically for head imaging. The basic performance of the CNT x-ray source array was characterized. By rotating the object in discrete angular steps, a potential s-HCT configuration was emulated. The collected projection images were reconstructed using an iterative reconstruction algorithm developed specifically for this configuration. Evaluation of the image quality was completed by comparing this image of the ACR CT phantom obtained with the s-HCT to that obtained by a clinical CT scanner. Results: The CNT x-ray source array was found to have a consistent focal spot size of 1.3×1.1 mm2 for all beams (IEC 1.0). At 120 kVp the HVL was measured to be 5.8 mm Al. Axial images have been acquired with slice thickness 2.5 mm to evaluate the imaging performance of the s-HCT system. Contrast-noise-ratio was measured for the acrylic (120 HU) and water (0 HU) materials in the ACR CT 464 phantom Module 01. A value of 5.2 is reported for the benchtop setup with an entrance dose of 2.9 mGy, compared to the clinical measurement of 30.5 found at 74.5 mGy. These images demonstrate that the s-HCT system based on CNT x-ray source arrays is feasible. Conclusion: Customized CNT x-ray sources were developed specifically for head CT imaging. The feasibility of using this source array to construct a s-HCT scanner has been demonstrated by emulating a potential CT configuration. It is shown that diagnostic quality CT images can be obtained using the proposed system geometry. These preliminary images provide confidence that a s-HCT system can be constructed for clinical evaluation.


Objective To investigate cancer stem cell-like property of colon carcinoma cell line HCT116 for further exploration on the biological features of colon cancer stem cells. Methods HCT116 cells were cultured in serum-free medium,and the proliferation and differentiation of the cells were observed. The growth,proliferation and differentiation of the cloned HCT116 spheres were subsequently observed,and the sphere formation rate of HCT116 cells was calculated by limiting dilution assay. Oncogenicity of HCT116 cells was determined by subcutaneous injection of cells (5×103 or 5×104) into flank of female nude mice to observe tumor growth for 3-8 weeks,and histological features of xenografts were observed. Phenotypic characterization of HCT116 cells,including expressions of CD133,CD44,ABCG2 and CD133,were respectively detected by flow cytometry,immunofluorescence imaging,RT-PCR and Western blotting. Immunohistochemical staining was carried out to detect the expression of CK20 in HCT116 spheres. Results The primary formative rate of sphere of HCT116 cells in serum-free medium was 41.47%±1.28%,and the secondary generation of HCT116 cells still kept a high sphere formative rate of 32.53%±2.32%. The first generation of HCT116 cells formed spheres after a 72-hour culture,and such a capability of sphere formation could be maintained at least for 15 generations. The xenograft tumors formed in nude mice 5-6 weeks after subcutaneous injection of 5×103 HCT116 cells. A majority of HCT116 was CD133+CD44+ cells which expressed ABCG2 protein. CK20 could be detected in the HCT116 sphere at day 4 during the course of differentiation. Conclusion Cancer stem cell-like property is observed in the majority of HCT116 cells,indicating that most of HCT116 cells might be putative colon cancer stem cells. Therefore,HCT116 cell line can be taken as an appropriate model for further study on the function of colon cancer stem cells.

The Keck telescope segments were manufactured by stressed mirror polishing of large circular pieces of Zerodur that were then cut into hexagons and finished by Ion Beam Figuring (IBF). It has long been believed that this process results in segments with little or no edge effects. As a result, this same general approach is planned for segment manufacturing for the Thirty Meter Telescope (TMT) and the European Extremely Large Telescope (E-ELT). However, recent measurements at the Keck telescope suggest that at least some of the Keck segments have significant aberrations within 60 mm of the edge. These aberrations impact the telescope phasing and the overall telescope image quality. We present interferometric measurements of multiple Keck segments, characterizing the surface errors near the edges over spatial periods from ~5 cm down to ~1 mm. We show that the largest phasing and image quality effects are due to plateaus of unremoved material, left behind after IBF as a result of obscuration by the IBF supports. Apart from these plateaus, the edge quality is relatively good, though not as good as in the segment interiors. Some residual phasing and image quality effects remain, and these are not currently understood.


Energy harvesting from human motion for body worn or implanted devices faces the problem of the wearer being still, e.g. while asleep. Especially for medical devices this can become an issue if a patient is bed-bound for prolonged periods of time and the internal battery of a harvesting system is not recharged. This article introduces a mechanism for wireless energy transfer based on a previously presented energy harvesting device. The internal rotor of the energy harvester is made of mild steel and can be actuated through a magnetic reluctance coupling to an external motor. The internal piezoelectric transducer is consequently actuated and generates electricity. This paper successfully demonstrates energy transfer over a distance of 16 mm in air and an achieved power output of 85 μW at 25 Hz. The device functional volume is 1.85 cm3. Furthermore, it was demonstrated that increasing the driving frequency beyond 25 Hz did not yield a further increase in power output. Future research will focus on improving the reluctance coupling, e.g. by investigating the use of multiple or stronger magnets, in order to increase transmission distance.


Software supply-chain attacks target components that are integrated into client applications. Such attacks often target widely-used components, with the attack taking place via operations (for example, file system or network accesses) that do not affect those aspects of component behavior that the client observes. We propose new active library learning and regeneration (ALR) techniques for inferring and regenerating the client-observable behavior of software components. Using increasingly sophisticated rounds of exploration, ALR generates inputs, provides these inputs to the component, and observes the resulting outputs to infer a model of the component's behavior as a program in a domain-specific language. We present Harp, an ALR system for string processing components. We apply Harp to successfully infer and regenerate string-processing components written in JavaScript and C/C++. Our results indicate that, in the majority of cases, Harp completes the regeneration in less than a minute, remains fully compatible with the original library, and delivers performance indistinguishable from the original library. We also demonstrate that Harp can eliminate vulnerabilities associated with libraries targeted in several highly visible security incidents, specifically event-stream, left-pad, and string-compare.


The three articles which constitute this special section emanate from a oneday conference bearing the same title.' The title draws in part upon Tom Nairn's The Break-up of Britain. First published as the movement for devolution was gathering momentum under the Callaghan government, Nairn's book helped to set the agenda for some of the wider-ranging debates which prevailed. The tide receded following the Scottish and Welsh referenda of March 1979 and the onset of 18 years of Conservative government committed to maintaining the union intact. But since the return of a Labour government in May 1997, things have changed again. With the creation of a Scottish parliament, a Welsh assembly, a genuine powersharing executive in Northern Ireland and a stronger emphasis upon regionalism in England it seems appropriate once more to ask some basic questions about the body politic. Will the union survive? Can the centre hold? Can an ever greater socio-cultural diversity continue to find common focus in some sort of subjective identity known as 'British'? To raise these questions is to betray some of the complexities of the problem conceptual, definitional, empirical and, of course, historical. The UK is a union of different nations England, Scotland, Wales and the six north-eastern counties of Ireland (Northern Ireland). Quite apart from the obvious distinction between the 'UK' and 'Britain', there is the further query about national identity. According to one recent observer, notions such as 'British identity', 'English identity' and even 'Celtic identity' are somewhat artificial. What, then, constitutes a nation? If a nation is not defined simply by its political boundaries and jurisdictions, by what characteristics may it be recognised? How do nations emerge, fall away or mutate? In one sense nations may be defined by 'social' characteristics such as ethnicity, language, culture, belief systems, civic allegiances, customs and so forth. There may


A remedial investigation/feasibility study has been undertaken at Oak Ridge National Laboratory (ORNL). Bechtel National, Inc. and partners CH2M Hill, Ogden Environmental and Energy Services, and PEER Consultants are contracted to Lockheed Martin Energy Systems, performing this work for ORNL`s Environmental Restoration (ER) Program. An on-site Close Support Laboratory (CSL) established at the ER Field Operations Facility has evolved into a laboratory where quality analytical screening results can be provided rapidly (e.g., within 24 hours of sampling). CSL capabilities include three basic areas: radiochemistry, chromatography, and wet chemistry. Radiochemical analyses include gamma spectroscopy, tritium and carbon-14 screens using liquid scintillation analysis, and gross alpha and beta counting. Cerenkov counting and crown-ether-based separation are the two rapid methods used for radiostrontium determination in water samples. By extending count times where appropriate, method detection limits can match those achieved by off-site contract laboratories. Volatile organic compounds are detected by means of gas chromatography using either headspace or purge and trap sample introduction (based on EPA 601/602). Ionic content of water samples is determined using ion chromatography and alkalinity measurement. Ion chromatography is used to quantify both anions (based on EPA 300) and cations. Wet chemistry procedures performed at the CSL include alkalinity, pH (water and soil), soil resistivity, and dissolved/suspended solids. Besides environmental samples, the CSL routinely screens health and safety and waste management samples. The cost savings of the CSL are both direct and indirect.


Prisoners have limited access to legal assistance. Many prisoners spend months or years awaiting a court date. A staggering 70 % of the prison population is yet to be convicted. Frequently the length of pre-trial detention exceeds the eventual sentence. Convicted detainees often stay longer in prison than their actual term because the prison administration has lost overview of lengths of sentence. Many people are detained for minor offences which can be associated with poverty. Release on parole or on probation is uncommon. Women and children who have become victims of violent crimes, such as human trafficking or rape, are kept in prisons for their own 'safety' rather than because they have committed any type of crime, as they don't have a safe place to stay. This practice is called "safe custody". The conditions under which prisoners are held are appalling, contravening all international human rights standards. For example, up to 200 inmates share one cell of just 40 m2 forcing them to sleep in turns. Juvenile and unconvicted offenders are often housed with convicted felons. Food, sanitation and hygiene are inadequate; violence and infectious diseases such as tuberculosis are rampant. It is reported that prisons become breeding grounds for disease, crime and religious fundamentalism.


A graph-theoretic approach to characterize discrete time crystals and use them as a complex quantum network simulator. Crystals arise as the result of the breaking of a spatial translation symmetry. Similarly, translation symmetries can also be broken in time so that discrete time crystals appear. Here, we introduce a method to describe, characterize, and explore the physical phenomena related to this phase of matter using tools from graph theory. The analysis of the graphs allows to visualizing time-crystalline order and to analyze features of the quantum system. For example, we explore in detail the melting process of a minimal model of a period-2 discrete time crystal and describe it in terms of the evolution of the associated graph structure. We show that during the melting process, the network evolution exhibits an emergent preferential attachment mechanism, directly associated with the existence of scale-free networks. Thus, our strategy allows us to propose a previously unexplored far-reaching application of time crystals as a quantum simulator of complex quantum networks.

Due to advances in automated manufacturing systems and automatic inspection equipment, complete inspection has drown increased attention recently and has become a widespread practice. In a complete inspection plan all of the items are subject to acceptance inspection If an item fails to meet the predetermined specifications, it is rejected. In this paper, economic complete inspection plans are developed in situations where rejected items are reworked Complete inspections based on the performance variable of interest or a variable which is correlated with the performance variable are considered. Cost models are constructed which involve cost incurred by imperfect quality rework cast and quality inspection cost Methods of finding the optimal complete inspection plans are presented and numerical examples are given.


Ð Four experiments testing for telepathic communication of emotions, evoked by slides, between a group of a senderso and a group of a receiverso using a total of 210 undergraduate students as subjects, are reported. Analysis of variance of aggregated data showed a significant difference among: a) believers in telepathy (n = 53), scoring below chance level, b) undecided (n = 105), scoring above chance level, and c) non-believers (n = 48), who did not deviate from chance level. Except for a minor deviation in the first experiment, the same pattern was obtained in all four experiments. The first picture presented exhibited a significant positive deviation from the value expected by chance. Hit score showed an inverted U-formed relationship to rated involvement, with negative scores for very high involvement values. Scores on an a opennesso test, administered at the end of Experiment 4, did not show any relationship to performance, except for a significant negative correlation between a belief-in-telepathy item and hit score. In general, the results from the first three experiments were replicated in the fourth experiment, where all conceivable experimental errors had been eliminated. A so-called Monte Carlo Method, which is free from all statistical assumptions, confirmed the results obtained by traditional methods. Except for sampling error, no probable a naturalo explanation of the findings could be found.


This work deals with the synchronical description of prepositional case constructions with the semantic component of the interior in Serbian and Slovenian. The examples used for analysis are excerpted from the novel Besnilo, by Borislav Pekic, written in Serbian and its translation into Slovenian, Steklina. The aim of contrasting the prepositional case constructions subsystem of these two languages is the identification of similarities and differences in the expression of semantic features within the prepositional case constructions with a spatial meaning on the paradigmatical level, while the translation equivalents are being analyzed on the syntagmatic level. The analysis points out that there are no bigger differences in the distribution of prepositional case constructions with the semantic component of the interior in Serbian and Slovenian. The use of the corresponding construction can be conditioned by the lexical meaning of the noun within prepositional case construction, the meaning of the verb and its valency, and also by its morphemic composition.


Whenever low-income housing projects fail to produce the desired result, the failure is attributed to a lack of community participation. When governments do not have the funds to launch a low-income housing programme, community participation is supposed to compensate for this lack of resources. There exists a considerable confusion about the exact meaning of the term "community participation". All sorts of activities (ranging from house construction to discussions about loan repayment schedules) by groups of people as well as by individual persons are classed under the term. This article attempts to clarify the term "community participation" with reference to urban low-income housing projects. In squatter settlement upgrading projects, the authorities regularize the illegal land tenure of squatters and provide basic infrastructure in the settlements. These interventions are expected to be sufficient incentives for the residents to start improving their houses. In sites-and-services schemes, the authorities provide serviced plots to the urban poor and expect them to produce their own houses, through individual or mutual self-help or the employment of small contractors.


THROUGHOUT HIS CAREER, Arthur Miller has shown a marked tendency to argue general propositions in colloquial terms. "Listen!" a character shouts in "That They May Win" (1944), a one-act play about returning veterans: "We the people gotta go into politics. Politics is just another way of saying how much rent you'll pay; and how much bread, chopped meat and milk your food dollar will buy, and what you'll have to pay for junior's new shoes! You have to go to those Senators and Congressmen you elected and say, 'Listen here, Mister! We're your boss, and you have to work for us!'" Later, of course, Miller became more adept at shaping an outlook with the mannerisms as well as the rational content of speech, but all his writing reveals his penchant for voicing ethical abstractions, usually of wide social relevance. This habit evidences high seriousness; unfortunately, it has also caused stylistic problems.


Hope, Perdita J., Ian Chapman, John E. Morley, Michael Horowitz, and Gary A. Wittert. Effect of diet on the response to leptin in the marsupial Sminthopsis crassicaudata. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R373–R381, 1999.—The aim of this study was to determine in the marsupial Sminthopsis crassicaudata 1) the effect of leptin on food intake, body fat stores, and metabolism and 2) whether leptin can prevent a diet-induced increase in adiposity. In response to 21 days of feeding with mealworms (2.99 kcal/g, 30% fat), body weight (P , 0.0001) and tail width (P , 0.0001) increased, compared with control animals fed with laboratory diet (1.01 kcal/g, 20% fat). Subsequently, S. crassicaudata were randomly allocated to receive either laboratory diet or a choice between laboratory diet and mealworms. For 13 days, one-half of the animals in each dietary group received intraperitoneal human leptin (2.5 mg/kg twice daily), while the other one-half received phosphate-buffered saline. In animals receiving laboratory diet alone, leptin induced a decrease in body weight (P , 0.0001), tail width (P , 0.0001), and energy intake (P , 0.01). In animals receiving both laboratory diet and mealworms, leptin had no effect on body weight or tail width, although the proportion of laboratory diet eaten was reduced (P 5 0.0001), and there was a nonsignificant fall in overall energy intake (P 5 0.07). We conclude that in S. crassicaudata, 1) a high-calorie, higher-fat diet induces an increase in adiposity and 2) leptin induces weight loss, but 3) an increase in dietary calories and fat content is associated with resistance to the actions of leptin.


Background: Bronchial asthma has varied presentations in children and its global prevalence is increasing in children. Asthma is associated with various risk factors and comorbidities. The objective of the study was to assess the severity, level of control of asthma in children without comorbidities, with obesity and allergic rhinitis. Methods: An observational study was conducted in 150 children aged 5-15 years diagnosed to have asthma as per GINA (Global initiative for asthma) guidelines 2019, who are being followed up in the department of pediatrics in asthma clinic in RRMCH. Parents were interviewed and the following data collected like demography, allergy history, treatment history, comorbidities, family history of atopy. Detailed clinical examination was performed including anthropometry-weight, height and BMI recording. Pulmonary function tests was done in all children.Results: Out of 110 children without comorbidities, 108 (98.2%) had well controlled, 2 (1.8%) had partly controlled, 0 had uncontrolled. Out of 19 children with obesity, 5 (26.3%) had well controlled, 9 (47.4%) had partly controlled, 5 (26.3%) had uncontrolled. Out of 15 children with allergic rhinitis, 6 (40%) had well controlled, 8 (53.3%) had partly controlled, 1 (6.7%) had uncontrolled. With a p value of 0.001, it is statistically significant.Conclusions: Our study shows severity of asthma increases in children having comorbidities like obesity and allergic rhinitis when compared with children without comorbidities with a significant association. Our study also shows that children having comorbidities like obesity and allergic rhinitis have poor level of asthma control when compared with children without comorbidities with a significant association.


This thesis will document and analyze the experience of two members of the Shear Genius team, Mr. Abdulrahman Hamid and Mr. Colin Wattigney, as they worked to complete the CME Senior Capstone Project. This team, under the leadership of CEO Ethan Veazey, developed the Blade Bandit, a lawn mower blade sharpening system conceptualized by Mr. Jacob Moorhead. Ms. Kristen Gaddis, Mr. Nick Rocco, and Ms. Allie Winters were also members of Shear Genius. The team members had educational backgrounds in the realms of engineering, business and accountancy. The combination of these disciplines allowed for the simulation of a real business group and helped prepare the team members for the situations that they would face as members of industry.
After months of planning, designing, and redesigning, the Shear Genius team was able to develop a process in which a functional Blade Bandit could be produced quickly and consistently. The team gained vast amounts of experience and worked together as a cohesive unit to overcome the many obstacles that were faced. This thesis will describe iterations of the Blade Bandit, the business model used, and the changes made along the way. It will also provide insight into all decisions made over the course of the project.


Apoptosis, or programmed cell death is a physiological process occuring in the healthy multicellular organism. This process is used to explain many of the events which difficult to understand in basic basic medical sciences. It' known that free radicals are one of main factors causing cell death. They affects also nucleic acids (DNA) which reserve genetic code of cells. If the message coming from main cells cannot be read, the genetic code of cells change and they can die.

The characteristics and the optimum design of a metal detector are studied theoretically and experimentally. This metal detector is expected to be mounted on an unmanned submersible and to be used for the location finding and tracing of the submarine telecommunication cables. The detector consists of one exciting coil and two receiving coils which are fixed perpendicularly to the excitation coil. The receiving coils detect the magnetic field induced by the eddy current flowing in the outer conductor of the submarine cable. Although the detection range is narrow, about 40 cm, this detector has some advantages that the other cable-locating sensors do not have. The detecting characteristics are calculated numerically under several assumptions and compared with experimental results.


Owing to a great variety of uncertainties,the actual power system usually faces certain vulnerabilities related to the inner and outer disturbances to make it go into abnormal operation states.Described in this paper are several possible typical precipitating factors making the power system go into abnormal operation states,including supernormal changes in the power grid structure,dramatic power fluctuation of intermittent energy,rapid ramping or dropping during peak or valley load periods.By analyzing the typical scenes of abnormal operation states and tendencies of power networks,the causality between scenario and state and the difference between state and tendency are sorted out for power systems.On this basis,state features and tendency indices are set up to embody the abnormal operations of power systems,and the corresponding assessment framework and methods are also given.Furthermore,guiding principles for parameter setting are given,and feasible comprehensive evaluation methods for abnormal operation states and tendencies are analyzed.


Structural materials with higher melting temperatures and better mechanical properties than superalloys are in high demand in refractory applications. A promising WReTaMo refractory high‐entropy alloy (RHEA) with high strength at 1600 °C is fabricated by vacuum arc melting. The WReTaMo RHEA has a body‐centered cubic (BCC) structure with a maximal compressive strength of 1140 MPa and Vickers microhardness of 654 HV at room temperature. The alloy displays a strong resistance to high‐temperature softening, showing the high maximal compressive strength of 244 MPa at 1600 °C. The deformation of the WReTaMo RHEA compressed at 1600 °C maybe resulted from the grain boundary sliding, which leads to the propagation of the cracks along grain boundaries. Face‐centered cubic (FCC) phase forms at the surface region of samples annealed above 1800 °C due to the diffusion of carbon atoms by gas carburizing in the graphite crucible at such high temperatures. The increase in hardness at temperatures above 1600 °C results from the solid solution strengthening of dissolved carbon. The forming ability of the WReTaMo RHEA is also discussed. This work presents a promising high‐temperature structural material and fills the vacancy of the mechanical properties of Re‐containing RHEAs at 1600 °C.

Most of the present finance software is designed by simply simulating the traditional accounting format, and automatically inherits its defects. This paper puts forward the defects that exist in the traditional accounting format. It also analyzes the enormous effects ERP environment has on the various aspects of accounting as well as the remarkable differences between the ERP environment and the traditional accounting setting. Finally, it points out that ERP accounting software is supposed to apply the advanced management and accounting concepts of ERP to the innovations of the traditional accounting format instead of simply mimicking the traditional accounting format so as to construct the new enterprise accounting informationalized model in the ERP environment.


Operation of nuclear reactors is requires a high level of safety, both for the safety of the reactor itself or its surroundings. Important component in nuclear reactor safety parameters are met is that the integrity of nuclear fuel in reactors. One form of fuel used in High Temperature Gas-cooled Reactor (HTGR) is a spherical shape, where the sphere is composed of small balls called by the kernel that is wrapped with a layer of TRISO (tri-structural isotropic). One of the problems in the manufacture of fuel is the determination of the temperature distribution between the core and TRISO coating. The thermal load may cause the outbreak of the TRISO fuel. The determination of the temperature distribution on TRISO fuel kernel can not be calculated manually, but it should be done by modeling. Modeling is an effective and inexpensive to perform especially concerning human safety trials. The results of modeling of temperature distribution between the fuel core and a buffer layer is approximately 1002.6 °C with a...


Additive Manufacturing (AM) is a production process that does not remove or remove some of the material in the production process but adds material. The added material is extruded by means of Fused Deposition Modeling (FDM) technique. The way it works is to create a number of layers or layers one on top of the other. The software application used is Inventor to create 3D models in the form of STL files. Then the STL file is opened in the Ultimaker Cura (UC) application, to create a Numerical Code in G-Code which is used as a control on a 3D printing machine. The filler material used to produce molds is Polylatic Acid (PLA). PLA filament is very widely used in the manufacturing process, because this PLA can produce strong and very neat prints. The general print temperature of PLA is between 180oC to 220oC. The purpose of this test is to find out the steps for implementing the AM process and to analyze the mechanical properties of the AM product using the FDM technique. In this study, the printed material was based on ASTM D638 type IV. This research was conducted to determine the effect of variations in infill and printing speed on printed results, with a horizontal orientation of the printing angle of 0o. The infill variations are line infill and concentric infill with printing speeds of 50mm/s and 60mm/s. The research procedure is to make a 3D printing model, the manufacturing process, and the testing process. The results showed that the choice of infill and speed printing variations had an effect on the mechanical properties. The mechanical properties of printing products differ according to the mode and speed. The infill line mode provides greater mechanical strength than that produced in concentric infill. At a speed of 60 mm/s, the product strength of the infill line mode is 32.5 MPa greater than the 27 MPa strength of the printed product from the concentric infill mode.


This study analyzes the usage of the Spanish adjectival sin + infinitive verb construction (un libro sin terminar 'an unfinished book') and the no + past participle construction (un libro no terminado 'an unfinished book') in historical corpus data, with the objective of quantitatively assessing Pountain's (1993) analysis of the emergence of adjectival sin + INF as motivated in part by register formality. A logistic regression analysis finds that the usage of adjectival sin + INF over no + PP is significantly favored by the text register of Prose Fiction, and significantly disfavored by the register of Legal Texts. Furthermore, this preference increases with time in the register of Prose Fiction. These findings support Pountain's claim, in showing that register effects significantly influence the usage of the novel construction. Ultimately, this study stresses the importance of measuring register effects in the analysis of language change in corpus data.


Neural networks have been applied very successfully in the identification and control of dynamic systems. When designing a control system to ensure the safe and automatic operation of the gas turbine combustor, it is necessary to be able to predict temperature and pressure levels and outlet flow rate throughout the gas turbine combustor to use them for selection of control parameters. This paper describes a nonlinear SVFAC controller scheme for gas turbine combustor. In order to achieve the satisfied control performance, we have to consider the affection of nonlinear factors contained in controller. The neural network controller learns to produce the input selected by the optimization process. The controller is adaptively trained to force the plant output to track a reference output. Proposed Adaptive control system configuration uses two neural networks: a controller network and a model network. The model network is used to predict the effect of controller changes on plant output, which allows the updating of controller parameters. This paper presents the new adaptive SFVC controller using neural networks with compensation for nonlinear plants. The control performance of designed controller is compared with inverse control method and results have shown that the proposed method has good performance for nonlinear plants such as gas turbine combustor.Copyright © 2006 by ASME

A neutron star in a compact binary is expected to be well-approximated by a barotropic flow during the inspiral phase. During the merger phase, where tidal disruption and shock-heating occur, a baroclinic description is needed instead. In the barotropic case, a Hamiltonian formulation potentially offers unique benefits for numerical relativity simulations of the inspiral phase, including highly accurate conservation of circulation and superconvergence of the fluid variables, and is actively being explored. In this work, we investigate the viability of a Hamiltonian formulation in the baroclinic case. At odds with the barotropic case, this formulation is non-conservative, yet it can be treated well with approximate Riemann solver algorithms since the non-conservative terms vanish across genuinely nonlinear fields. Nonetheless, using numerical 1-dimensional shock tube tests we find that the weak solutions of the Hamiltonian system differ from the standard ones obtained by enforcing conservation of rest mass density, momentum density, and energy density across discontinuities. We also show that barotropic Hamiltonian formulations can admit shockwaves at fluid-vacuum interfaces, which may be related to the unstable behavior of stellar surfaces observed in past numerical tests. In light of the unphysical weak solutions, we expect that in future implementations of the Hamiltonian formulation of hydrodynamics in numerical relativity it will be necessary to use an explicitly barotropic formulation during the inspiral phase, and then switch to a robust baroclinic formulation prior to merger.


This study was undertaken to produce an annotated union catalog of local history resources on Region 8 in 127 libraries and museums throughout Region 8 and major academic institutions in Manila and abroad. This study used the descriptive method of research, particularly the documentary analysis type. The bibliographic data were taken from shelf-list and card catalogs (non-automated libraries), online public access catalog (OPACs), and WebOPAC. Uncatalogued materials were processed and provided with subject headings based on the Sears's List of Subject Headings and LCSH or combination of both, Filipiniana Subject Headings were used for "local terms', if no equivalent in English "local term" were indicated. The List of subject headings, annotations and locations was provided in this study. The data were then recorded, analyzed and interpreted. This study identified a total of 2,483 titles or 4,894 volumes of materials documenting the Region 8' arts and culture, history, language, and literature, education, economic, social, political, and intellectual life. These publications include books, journals, microforms, maps, periodical articles, pictures, souvenir programs, and unpublished materials. It was found out that majority of collections found in Region 8 were in printed forms while Manila and abroad has a good number of local history resources in both print and non-print format. The collection covers a total of 2,646 different subject areas. The subject on Academic Achievement had the highest percentage from the unpublished materials followed by Tacloban City (Leyte, Philippines) – Notarial Records from the microform materials. Information agencies included in this study had existing policies and procedures in the preservation and conservation of these materials but only few have written preservation policies. This annotated union catalog would help researchers, historians and librarians in locating materials for historical studies in Region 8.


Experimental results of natural gas hydrates formation from ice obtained under static conditions in the batch reactor applying the method of thermal cycling have been given. Hydrate forms subdivided according to their morphological features have been shown: powder and layered growth, retained ice shapes, and whisker crystals. The conducted experiments have defined effects of the thermal cycling regime on forms of obtained hydrates: decreased rates of heating/cooling results in an increase of a share of whisker crystals. The rate of decomposition of loose retained ice shapes in the form of hydrate has been defined to be 2.3 times faster than that of powder and dense layered hydrates.


Rationale: Venous thrombus embolism (VTE) includes deep-vein thrombosis (DVT) and pulmonary embolism (PE) which may be an initial symptom for patients with cancer. PE has diverse clinical manifestations and is a rare complication of testicular tumor (TT). Patient concerns: Here, we report a 21-year-old man admitted to our hospital due to syncope. Diagnoses: Clinical examinations upon admission demonstrated PE resulting in syncope. Further, a malignant TT, liver metastasis, and inferior vena cava (IVC) thrombosis were diagnosed. Interventions: Low molecular heparin was administered immediately after PE was diagnosed. Outcomes: The patient suffered from cardiac arrest on hospitalization. Lessons: Physicians should consider the possibility of TT when a young male patient presents with syncope and is diagnosed with PE that cannot be explained by a common cause. Treatment for TT and PE should be performed as early as possible to improve the prognosis of patients combine with TT and PE.


Asthma is a Th2‐mediated inflammatory disease resulting from the cooperation of many cell types, receptors, and cellular events, many of which are caused by signal transduction through G Protein Coupled Receptors (GPCRs). Current therapies for asthma target GPCRs but prolonged use results in increased airway hyperreactivity and receptor desensitization. RGS (Regulator of G protein Signaling) proteins negatively regulate signaling through GPCRs by accelerating the rate of GTP hydrolysis of the α subunit of the heterotrimeric G protein. RGS 16 was originally identified as an IL‐2 responsive gene in human T cells. Th2 cytokine production is increased in transgenic mice expressing RGS16 in CD4+ and CD8+ T lymphocytes in a mouse model of allergic inflammation and trafficking of these cells to the lung is reduced. High RGS16 levels are found in germinal center T cells, and upregulation of RGS16 mRNA results in impaired migration towards CXCL12. RGS16 is hypothesized modulate T cell trafficking to the lung in response to inflammation. We are currently assessing the role of RGS16 in T cell responses. We have characterized RGS16 expression by intracellular flow cytometry. We have knocked down RGS16 expression in Jurkats and assessed effects on Ca2+ mobilization, CD69 and T Cell Receptor (TCR) expression levels, intracellular localization by immunofluorescence and immunohistochemistry, and tyrosine phosphorylation levels. Preliminary results show no change in expression levels of the α/β TCR when RGS16 is knocked down, but higher phosphorylation levels of ZAP70 and ERK. Taken together, these results suggest that RGS16 has a negative effect on signaling through an activated TCR. Determination of a role for RGS16 in T cell responses may provide another mechanism by which therapeutics can be developed and administered in the treatment and control of asthma and allergic inflammation.


Given concerns that Alcoholics Anonymous (AA) might disempower already disenfranchised groups by focusing attention on self scrutiny and away from social action, this article explores how a cohort of black women members in Chicago portray the role of individual and social forces in their addictions. Despite challenges including histories of sex work and abuse, these women describe themselves as empowered in their recovery efforts and as more successful in AA than their male peers. Their reported success reflects their innovative application of a women-only meeting. Through this meeting, members develop a practice of "openness" that is in some ways at odds with AA's customary self-focus, especially as it becomes grounds to exchange stories about social precipitants of addiction and to strategize ways to assert themselves in their relationships. Rather than enacting a pregiven version of AA, these women interpret the program in creative ways that allow them to accomplish a broad set of objectives.
