Despite promises of "completely security" for banks and other organizations that need to transfer data, most research into quantum cryptography has until recently been confined to the lab. Last month, however, physicists took a major step towards commercializing the technology by using "quantum keys" to transfer data securely in a commercial telecommunications network in Vienna, Austria.

Cotton fabrics and polyester fabrics are treated with PCM(phase change material) microcapsule by padding process,and the properties of thermal storage and air permeability of thermoregulation fabrics are evaluated by DSC and air permeability meter. The optimal finishing process is described as follows: twice padding with a dip and a rolling way,dosage of microencapsulated phase change material 250 g /L,curing at 110 ℃ for 120 s. Thermal analysis by DSC shows that the heating and cooling rate of the thermoregulation fabrics slows down significantly than that of the ordinary fabrics,which demonstrates intelligent thermoregulation function,moreover,the air permeability of the fabric is slightly increased. With this method,the thermoregulation fabrics can be prepared with a certain durability to washing,and the effect on the polyester fabric is much better.


Abstract:In these philosophical meditations for a Reykjavík art exhibit, Icelandic author Oddný Eir looks into the open spaces created in art and finds opportunities for asking new questions.


Strong symmetry of shocks allows for the formation of a monetary union with low costs due to losing monetary sovereignty. I employ vector autoregression to identify structural shocks and study their symmetry through time. I find that the underlying structural shocks have not changed significantly and remain rather asymmetric, particularly demand shocks.

This paper discusses the online identification of non-local static hysteresis functions, which are encountered in mechanical friction, magnetic materials, and piezoelectric actuators. The hysteresis function is modeled using a superposition of elementary extended stop-type hysteresis operators. Each hysteresis operator is defined by one characteristic parameter and one state variable. By choosing the characteristic parameters in advance, the identification leads to a linear least squares estimation of the weighting parameters. This can be implemented recursively for the online estimation of these parameter, to track their slow variations, e.g., due to temperature changes. The developed modelling and identification approach is tested by means of simulations and experiments on a piezoelectric actuator. For the simulations, for both static and dynamic systems, containing a hysteresis function are considered.


The virus responsible for the pandemic that has affected 152 countries worldwide is a new strain of coronavirus (CoV), which belongs to a family of viruses widespread in many animal species, including birds, and mammals including humans. Indeed, CoVs are known in veterinary medicine affecting several species, and causing respiratory and/or enteric, systemic diseases and reproductive disease in poultry. Animal diseases caused by CoV may be considered from the following different perspectives: livestock and poultry CoVs cause mainly "population disease"; while in companion animals they are a source of mainly "individual/single subject disease". Therefore, respiratory CoV diseases in high-density, large populations of livestock or poultry may be a suitable example for the current SARS-CoV-2/COVID-19 pandemic. In this review we describe some strategies applied in veterinary medicine to control CoV and discuss if they may help to develop practical and useful strategies to control the SARS-CoV-2/COVID-19 pandemic.


Glass transition and effects of pressure and shear stress on atomic configuration are investigated by means of molecular dynamics simulation. An embedded atom method potential is used for the atomic interaction. A model crystal for Cu is melted and quenched to realize the glass state. Atomic configuration in the glass is examined through the radial distribution function. External stress is applied and displacement of atoms is monitored to investigate the mechanism of mechanical relaxation. Larger displacement of atoms is observed under a shear stress.


The text 4Q369, designated by its editors Harry Attridge and John Strugnell as the "Prayer of Enosh," was published in 1994.' I should say at the outset that the designation "Prayer of Enosh" strikes me as somewhat unfortunate. While it is true that the words of this text are in large measure addressed to God-hence, it does indeed seem to be some kind of prayer-the editors themselves suggest that only the first column of the first fragment actually contains a prayer of Enosh, while the second column of that fragment-by far the largest piece of readable text-they believe to be the prayer of a different figure, possibly Enoch. In truth, it seems to me unlikely that there are two different speakers here, and still less likely that the speaker of this second column is Enoch, for the simple reason that, as we shall see presently, this section is actually devoted to the subject of the people of Israel and its founder, Jacob. Of course, the speaker of this section could be Enoch if he were discoursing prophetically about Jacob/ Israel, but there is no indication that that is the case. The speaker of column 2, at any rate, is talking about events that have already taken place. In the following I would like to examine a few of the lines of this column 2 in greater detail. What I propose to do is not so much to comment, stricto sensu, on the words of the text as to sketch briefly the exegetical environment within which they were written, drawing


The Next Generation Transit Survey (NGTS) has now been operating for six years, discovering and characterizing transiting exoplanets around bright stars. We outline the NGTS project, including the Andor CCD cameras used to perform high-precision time-series photometry. We quantify the photometric precision for a sample of over 20,000 bright star observations. We find for single NGTS telescope observations we achieve a 30-minute photometric precision of 400 ppm at low airmass. This is in good agreement with the photometric noise predicted using a four-component noise model. We find that the photometric noise for bright stars (G < 12) is dominated by atmospheric scintillation. We also present details of the NGTS multi-telescope observing mode, whereby 12 telescopes can be used simultaneously on a single target star to achieve a 30-minute photometric precision of 100 ppm. Finally, we describe a new generation scientific CMOS camera that we will be testing on-sky at the NGTS facility to determine if it can compete with state-of-the-art CCD cameras used for high precision bright star photometry.


Consideration is given to: variations in the Gauss coefficients of the geomagnetic potential over the last several hundred years; eccentric geomagnetic dipole drift; and evidence for geomagnetic jerks from 1931 to 1971. Among other topics discussed are: models of the geomagnetic field in western Europe from 1960 to 1980; the external and internal parts of the geomagnetic jerk of 1970; secular variation of the magnetic mean energy density at the source layer depth; and motions at the core surface in the geostrophic approximation. Consideration is also given to: the unpredictability of geomagnetic secular variation; the use of short-term core-mantle coupling and geomagnetic variation impulses as Lagrangian tracers of core motions; and a comparison of two sequential geomagnetic polarity transitions in the upper Olduvai and the lower Jarmillio in the Southern Hemisphere.


A simple model predictive control strategy based on reduced feedforward neural network (FNN) models is proposed. Under some physical constraint conditions, the short-prediction-horizon predictive control algorithm can carry out the offset-free performance for a class of nonlinear systems with input/output multiplicities. The main issue is to specify the input/output patterns for neural network architecture, and a stable, minimum-phase mode is added to reduce control structures that involve off-line identification algorithms and graphic-based determination. Finally, three examples of chemical reactors exhibiting unstable or nonminimum-phase dynamic behaviors are demonstrated to verify the proposed control scheme.


This research investigates the Attention Deficit/Hyperactivity Disorder (ADHD) in a school context from a dimensional perspective. It took part of the study 107 children with mean age of 12,37 years. It was used the ADHD's Scale - teacher's version and an adapted form for parents in addition to computer tasks to measure cognitive processing. The prevalence of Hyperactivity, according to teachers and parent's report, was consistent with the literature (4,7%). Attention deficit correlated with all measures of cognitive processing. Hyperactivity and Antisocial Behavior correlated with working memory measures only when the first was assessed by teachers and the second was assessed by parents. In this sense, it was found low concordance between informants regarding ADHD behavior dimensions. However, teacher's report seems to be according with contemporary literature. It was concluded that dimensional investigation can provides relevant information related to demographic and cognitive characteristic of ADHD.


Web forums are platforms for personal communications on sharing information with others. Such information is often expressed in the form of advice. In this paper, we address the problem of advice-revealing text unit (ATU) extraction from online forums due to its usefulness in travel domain. We represent advice as a two-tuple comprising an advice-revealing sentence and its context sentences. To extract the advice-revealing sentences, we propose to define the task as a sequence labeling problem, using three different types of features: syntactic, contextual, and semantic features. To extract the context sentences, we propose to use a 2 Dimensional CRF (2D-CRF) model, which gives the best performance compared to traditional machine learning models. Finally, we present a solution to the integrated problem of extracting both advice-revealing sentences and their respective context sentences at the same time using our proposed models, i.e., Multiple Linear CRF (ML-CRF) and 2 Dimensional CRF Plus (2D-CRF+). The experimental results show that ML-CRF performs better than any other models studied in this paper for extracting advice-revealing sentences and context sentences.

The magneto-optic Kerr angle spectrum of a single crystal of MnBi was measured at room temperature and also calculated with the TB-LMTO methods including the spin-orbit inter action. Previously measured Kerr spectra with thin films had two negative peaks, except for one film grown in ultra high vacuum. The later had a first peak and a shoulder at the second peak position, indicating the second originated from oxygen in the other films. Comparing first-principles calculations and previous thin-film results with our single crystal data indi cated that the second peak originated from the combination of a weak intrinsic MnBi peak and oxygen in the sample. The complex dielectric constants and magneto-optic Kerr spectra of electro-polished (100), (110), and (111) planes Ni2MnGa were measured. Also optical and magneto-optical spectra were calculated with the TB-LMTO methods including the spin-orbit interaction. Measured Kerr and optical spectra with three surfaces at room temperature had the same peak positions, but different amplitudes. The difference between (100) and (110) sur faces are probably due to the polishing process, not intrinsic bulk properties. Angle-dependent reflectance difference spectroscopy of (100), (010), and (001) planes GdsSigGeg, and (100) plane Tb^Si^Ge^, which are optically anisotropic materials, were measured with the Kerr spectrometer by rotating the samples. The replacing the rare earth Gd to Tb atoms and 10 % changing Ge to Si atoms did not change the spectra much. The complex dielectric con stants of (100) and (001) planes Gd^Si^Ge^ were measured by the spectroscopic ellipsometer. Two reflectance differences, measured by the Kerr spectrometer at near normal incidence and converted from the dielectric constants measured by ellipsometer at oblique incidence, agreed well.


Leadership succession planning is a sine qua non for any organization desiring sustainable performance, growth and internal efficiency, and avoiding vulnerability to retrogression and collapse. The study sought to determine the planning strategies for leadership succession in some construction companies in north east of Nigeria. A modified questionnaire was deployed to elicit responses on nine-item planning strategies for leadership succession from 93 CEOs of SMS construction companies in the study area. Mean and standard deviation were used to describe generated data from the respondents. An hypothesis was formulated (at 0.05 level of significance) and tested with T-test inferential statistics. The result showed that most of the planning strategies, bordering on recruiting and systematic training of potential successors, and designation and installation of the successor to the top leadership position, are rarely practiced. The study concluded that the construction companies in the study area needed to implement more of the leadership succession strategies for sustainable business.

In the US alone, 84 percent of women's HIV infections are due to heterosexual contact (CDC 2013).뀀ഀȠ Fifty percent of all people globally who are living with HIV/AIDS are women (UNAIDS 2009), yet, HIV-positive women's perspectives on prevention are mostly missing from the trajectory of scholarly literature on HIV/AIDS. I thought it imperative to go to the source (women living with HIV/AIDS) to get an insiders perspective on HIV prevention. Thirty HIV-positive Black women were recruited to participate in the study, which lasted seven months. These women live in a Florida innercity and range in age from 21 to 60. Qualitative methods were employed in a narrative analysis (Reissman 1993) of ethnographic data. Based on these women's narratives on 1) access to affordable housing, 2) access to comprehensive job training and welfare reform, and 3) the lack of comprehensive HIV/AIDS prevention interventions and education designed specifically for heterosexual men; I consider if a rights-based agenda is pivotal to the reduction of rates of HIV infection for African American women, one of the most highly infected populations in the US.


This paper adopts a social constructionist perspective to examine how the biodiversity 'claim' is constructed and contested at local level. A framework is deployed which is based on Hannigan's (1995) ideas that certain factors need to be present for an environmental claim to be legitimised within the international arena (i.e. scientific authority; popularisers; media coverage; symbolic and visual dramatisation; economic incentives and institutional sponsorship). Empirical research into the production and implementation of Oxfordshire's Biodiversity Action Plan and Farm Biodiversity Action Plans in England and Scotland is used as a vehicle to explore the legitimisation of the biodiversity claim at the local scale. The two strands of research highlight the current importance of biodiversity as a focus for environmental planning partnerships (although the extent of public 'buy-in' to the claim is unclear) and the way in which biodiversity as a 'buzzword' has been adopted by farmers with some reluctance and mainly for financial reasons. There is strong evidence that the scientific basis of the claim is crucial in terms of engendering support, and that the rhetoric employed at the local level is positive rather than a 'rhetoric of loss'. However, the need for further popularisation of the biodiversity issue is identified. Potential future lines of research enquiry are also outlined.


Based on the SiGe HBT (Heterojunction Bipolar Transistor) large signal equivalent circuit model, SiGe HBT models of the emitter diffusion capacitances and the collector diffusion capacitances are erected. Grounded on the forward transmit current and the inverse transmit current, it is taken into account the movable charge storage effect induced by the movable carries (including the forward storage charge and the inverse storage charge) , taking the Early Effect influence on carrier transport. The model holds the features of definite physical meaning and simple topology. And the large signal diffusion capacitances model, based on SiGe HBT equivalent circuit model, is embedded in the PSPICE. The model is simulated and analyzed in DC by the PSPICE, and the DC simulation results accord to that of other literatures, and transient state simulation results indicate that the response characteristic is good.

The paper aims to review and discuss on the issues of retirement confidence among Malaysian working adults both in the public and private sectors. Retirement confidence will only exist if there is proper retirement preparation among individuals. The method utilized for this conceptual paper is based on literature reviews from published journal, theses, conference proceedings and report. Previous literature on retirement studies supported that across countries around the world, individuals have little or lack of planning for their retirement. Malaysia as one of the developing nations is also currently experiencing the same situation where a majority of Malaysians are not prepared for retirement which eventually will influence their retirement confidence. A Through the review of past research showed that , there were many factors are associated with retirement confidence namely socio-demographic factors, expected age of retirement, attitude towards retirement, goal clarity of retirement, financial literacy, financial practices, financial socialization, and insurance planning. The Theory of planned behavior was suggested to be utilized in and incorporated into the proposed research framework.


Pulse shortening is a phenomenon common to all high-power microwave devices. Whereas in electron beam driven sources the electron beam propagation in the device may be for several microseconds or more, the microwave pulse duration is typically no greater than approximately 100 ns. Specific reasons for pulse shortening may vary among devices, but all explanation of the phenomenon put forth involve the introduction of plasma into the interaction region near the walls and/or the degradation of the beam quality. To gain a better understanding of pulse shortening in high power backward wave oscillators (BWO's), an investigation is being conducted at the University of New Mexico (UNM) on the UNM Long-Pulse BWO Experiment. Recent experiments have involved monitoring the beam current in the slow-wave structure (SWS) at different radii as a function of time. The current waveforms are correlated with the time histories of microwave pulses measured in separate experiments. The results reveal the appearance of electrons between SWS ripples at times corresponding to when the microwave signal peaks. A drop in the main beam current is observed shortly thereafter. Coatings of TiO2 and Cr have been placed on the inner surface of the SWS in an effort to suppress electron emission. Initial results with the TiO2 coatings have shown a measurable increase in microwave pulse width.


Diabetes has been described as a national health emergency, but the burden of the disease on men has not been fully recognised or responded to by health policymakers and practitioners. One man in 10 now has type 1 or type 2 diabetes, and a three‐fold increase in the incidence of diabetes in middle‐aged men has been predicted for the next 30 years. Peter Baker looks at the issues.


The hypersonic impulse tunnel of the University of Toronto Institute for Aerospace Studies (UTIAS) and Ryerson Polytechnical Institute (RPI) is a short-duration blow-down experimental wind tunnel capable of producing high-Mach-number flows (Ma ≈ 8). A generalized quasi-one-dimensional nonstationary flow analysis and associated total-variation-diminishing (TVD) finite-difference solution schemes, including aproximate Riemann solvers, are presented for predicting the high-temperature flows in such facilities. The analysis is used to investigate the operation of the UTIAS–RPI facility and produce performance data that are not always easily determined or available from experimental measurements. The thermodynamic state of the nozzle-exit flow and high-temperature or real-gas effects are assessed for this facility under various operating conditions. Numerical results, coupled with additional comparisons with available experimental data, demonstrate the range of test-section flows that may be achieved. They als...


Heterogeneous networks (HetNets) are expected to be one of the major performance enhancement enablers of LTE-Advanced. In order to protect pico-UEs from the strong macro interference, the macro eNBs need to reduce the transmission power during protected subframes instead of suspending data transmission introduced in 3GPP Release 10, scheduling strictly users in the vicinity of the macro eNBs. In this paper, based on low power (LP) almost blank subframes (ABS), we study a joint optimization of power allocation of ABS (called dynamic LP-ABS) and resource allocation to maximize the total throughput. The proposed algorithm takes into account the power allocation of ABSs in the marco eNB, the ABS partition and the UE association in all cells. Simulation results show that dynamic LP-ABS can effectively increase system throughput compared to the fixed LP-ABS and zero-ABS.


The electroabsorption modulators made of InGaAsP/InP multiple quantum wells (MQWs) are used in optical fibre communication links. EAMs also find applications in various other areas, an example being narrow pulse generation. The pulse width of generated pulses depends on EA modulator extinction efficiency. The operation of the devices is based on quantum confined Stark effect (QCSE). There have been several unsuccessful attempts to observe QCSE in Si/SiGe MQWs, and to exploit the effect to realize EAM and other devices. Recently, Kuo et al observed strong QCSE in Si based structures. So it is very much necessary to design a highly efficient SiGe MQW EA modulator. In this present work we have proposed several figure-of-merits (FoMs) for optimization of the performance.


A recent study of the psychological type profile of Christian youth workers in the UK drew attention to differences between the profiles of youth workers and clergy, and highlighted distinctive strengths and weaknesses that may be experienced by youth workers in Christian ministry. The present study, employing the Francis Psychological Type Scales among Canadian Baptist youth leaders (150 men, 186 women), cautions against generalizing on the basis of findings from the UK study. Among the Canadian Baptist youth leaders, compared with the UK Christian youth workers, there were higher proportions of introverts, sensing types, thinking types and judging types.


Deinking technology of ONP with cellulase or hemicellulase combined with laccase-mediator system was studied.Results showed the synergistic deinking effect when cellulase or hemicellulase combined with laccase-mediator system was used in deinking process.Brightness and strength properties of the pulps deinked synergistically were better than those of deinked pulp treated only with each individual enzyme.When deinking of ONP with cellulase and laccase mediator system,brightness of the deinked pulp after H 2O 2 bleaching reached 55.9%ISO.Breaking length was 2.13 km,and tear index was 6.43 mN·m 2/g.Comparing with the deiking with only cellulase or laccase mediator system,brightness was increased by 2.4%ISO and 3.8% ISO respectively.Breaking length was 30% higher than that of the deinked pulp treated with cellulase alone.When deinking with hemicellulase and laccase mediator system brightness of deinked pulp after H 2O 2 bleaching reached 60.4%ISO.Breaking length was 1.94 km,and tear index was 6.54mN.m 2/g.Comparing with the deinking with only hemicellulase or laccase mediator system,brightness was increased by 2.7%ISO and 8.3%ISO respectively and breaking length was 20% higher than that of deinked pulps treated with hemicellulase alone.


Many factors influence the impact that a nuclear war would have on both the environment and survivors. These factors include, although are not limited to, the type of nuclear weapons used, the amount of these weapons, and the time of year a war would take place. The effects that a major nuclear war would have on the environment would vary greatly depending on the factors previously mentioned. Some effects that would occur are: major climatic changes, destruction of most food crops, contamination of current food and water supplies, and the deaths of animals and insects that are crucial to the balance of the environment. The factors that influence the survivors also vary; however, certain problems have been predicted by researchers. Among these problems are psychological disorders, lack of food supplies, the elimination of medical relief, and exposure from both radiation and the changing environment. All these effects, as well as others, tend to give researchers a much different view of the effects that a nuclear war would have on the environment and survivors than has been predicted since before the mid nineteen-eighties.

In 399 B.C.Socrates,the philosopher,was put on trial and condemned to death in an Athenian court.His tragic death was mentioned in the same breath with the death of Jesus in the afterworld and became the blot of Athenian democracy,which became a puzzle of ancient and modern scholars.The trail and especially the charges caused his death,made people cast doubt on itself.


The construction of performance contours for high power transistors from measurements at a number of scattered load impedances has been investigated. Well-fitting . smooth circular contours are obtained by fitting equations derived from a simple model.


During 2008, the Connecticut Department of Transportation (ConnDOT) completed a Truck Escape Ramp (TER) in Avon, Connecticut. By incorporating multiple advanced technologies, the design solution addressed an urgent safety need while minimizing disruption to the surrounding businesses and residences. Existing conditions included a small site located in a mixed-use, upscale neighborhood; topographical constraints; a major arterial corridor with limited alternate routes; a steep, winding grade terminated by a signalized intersection; and, an accident history with two major runaway vehicle incidents during the previous three years. The TER design solution to stop runaway vehicles consists of a proprietary vehicle arrestor system to stop runaway vehicles; a Mechanically Stabilized Earth (MSE) wall system to support the TER above existing land contours; a complete concrete wall for safety and debris retention; and, an automatic sub-surface pavement heating system to prevent snow and ice accumulation and subsequent removal during winter storm maintenance. This paper discusses the role of these various TER components, along with its accelerated construction schedule and the performance of the TER to date.

We explore a flavor structure of quarks in the standard model under the assumption that flavor symmetries exist in a theory beyond the standard model, and seek their properties, using a bottom-up approach. We reacknowledge that a flavor-symmetric part of the Yukawa coupling matrix can be realized by a rank-one matrix, and a democratic-type matrix occupies a special position, based on Dirac's naturalness.


Objective: Adenomyosis' impact on obstetrical outcomes is investigated with detailed discussion of plausible pathogenesis. Discussion of management strategies to improve outcomes included. Methods of study: Terms utilized include 'adenomyosis', 'fertility', ' pregnancy', 'obstetrical outcomes', 'preeclampsia, 'fetal growth restriction', 'preterm labor', 'preterm prelabor rupture of membranes, 'in vitro fertilization, 'prelabor rupture of membranes', 'ultrasound', 'small for gestational age', 'cesarean section' Inclusion criteria are English, between January 1990-January 2023, randomized controlled trials, case controls, cohorts, case series, case reports, systematic reviews, and meta-analyses. Exclusion criteria are studies/articles completed prior to 1990, non-relevant, and non-English. Results: Limited literature exists evaluating the relationship between adenomyosis impact on obstetrical outcomes. However, amongst available literature there exists statistically significant relationship between adenomyosis and adverse obstetrical, neonatal outcomes such as: ectopic pregnancy, placental abruption, pre-eclampsia (PEC), gestational diabetes (GDM), low birth weight (LBW), intra-uterine growth restriction (IUGR), and preterm prelabor rupture of membranes (PPROM). Proposed physiologic mechanisms include disordered anatomic, functional, and immunological environment in the uterus. Proposed management strategies to improve obstetrical outcomes include removal of focal adenomyotic lesions and pre-treatment with GnRH agonists before conception. Conclusion: Adenomyosis has a multifactorial impact on obstetrical outcomes; treatment modalities do exist to improve the chances of conception and retaining a pregnancy. However, more research is required to not only further substantiate treatment modalities relationship to improve pregnancy; but also to clarify adenomyosis impact on infertility


In 2011, the White House announced the Materials Genome Initiative, which aims to cut down the cost and time required to discover, develop, and optimize a material and deploy it in a commercial system. One method of achieving this is by integrating experimental test methods, computational tools, and known knowledge databases. While the potential for computational models to speed and assist process-structure-property optimization is not a new concept, one of the key issues in the implementation of models in this space is the lack of a standard method of communication regarding the physical and chemical mechanisms that drive a materials system, and the amount and type of data required to accurately characterize that materials system in its entirety. This work focuses on developing process-structure-property-performance (PSPP) maps as this missing standard communication method. Here we detail the steps that should be taken to generate a map for any system, and then briefly discuss how those steps were applied to high-strength Al-Zn-Mg-Cu alloys. These alloys are highly utilized in aircraft applications and are extremely complicated and commercially viable materials which are repeatedly subject to re-optimization, and are thus a good example of the value of these maps and how they can be used.


In this study, the developed procedure of advection in volume of fluid (VOF) method is presented for free surface modeling. The fluid is assumed to be incompressible and viscous and therefore, Navier-Stokes and continuity are considered as governing equations. Applying Youngs' algorithm in staggered grids, it is assumed that fluid particles in the cell have the same velocity of the cell faces. Therefore, fluxes to neighboring cells are estimated based on cell face velocities. However, these particles can show different velocities between two adjacent cell faces. In developed model, the velocity in mass center of fluid cell is evaluated to calculate fluxes from cell faces. The performance of the model is evaluated using some alternative schemes such as translation, rotation, shear test, and dam break test. These tests showed that the developed procedure improves the results when using coarse grids. Therefore, the Modified Youngs-VOF (MYV) method is suggested as a new VOF algorithm which models the free surface problems more accurately.


In this paper I show that the following four properties of a convex subset Z of Rn are equivalent: 1. Z is the range of a vector measure. 2. Z is a limit of sums of segments. 3. The polar of Z is a central section of the unit ball of Lx. 4. The polar of Z is a projection body. A Z which enjoys one, and hence all, of the above properties is called a zonoid. Most of the results of this paper concern the class of zonoids and do not give simple geometric conditions characterizing membership in that class. Such conditions are known only for polytopes. Statements 1 through 4 above clearly imply that the study of zonoids belongs to several disciplines, among which are functional analysis, convexity and the geometry of polytopes. I have tried to make this paper self-contained enough to be accessible to any interested reader and have therefore restated some elementary definitions which would be unnecessary in a work directed at a specialist in one field. I have also tried to unify the study of zonoids, so many results known to some readers appear here with new—or sometimes old—proofs.

Response surface methodology was applied to optimize the extraction of proanthocyanidins from seeds of the new grape cultivar "Meili" using an accelerated solvent extraction(ASE) system.The optimal extraction conditions were found to be 13 min,1161 psi,80% and 80 ℃ for extraction time,pressure,methanol concentration and temperature,respectively.The maximum predicted extraction yield of proanthocyanidins under the optimized conditions was 6.817% indicating a relative error of 7.79% as compared with the actual value of 6.286% obtained after the third repeated extraction.The purity of proanthocyanidins under the optimized conditions was 41.02%.


A facile technique for the quantification of lignin solubility in ionic liquids has been established. This was used to examine the effect of the anionic and cationic components of ionic liquids on lignin solubility. Changing the cation was shown to have a significant effect on lignin solubility. Interaction of aromatic cations with the solute was significant in most, but not all, ionic liquids. The anion was required to have a minimum hydrogen bonding basicity value for lignin to dissolve, but after this point the anion effect on the overall lignin solubility was negligible relative to the cation.

WINDOW 4.0 is a publicly available IBM PC compatible computer program developed by the Building Technologies Group at the Lawrence Berkeley Laboratory for calculating the thermal and optical properties necessary for heat transfer analyses of fenestration products. This report explains the calculation methods used in WINDOW 4.0 and is meant as a tool for those interested in understanding the procedures contained in WINDOW 4.0. All the calculations are discussed in the International System of units (SI). WINDOW 4.0 is the latest in a series of programs released by the Lawrence Berkeley Laboratory. The WINDOW program has its roots in a paper detailing a method for calculating heat transfer through windows [Rubin, 1982]. WINDOW 4.0 replaces the widely used 3.1 version. Although WINDOW 4.0 is a major revision, many of the algorithms used in WINDOW 4.0 build upon those previously documented [Arasteh, 1989b], [Furler, 1991]. This report documents the calculations that are unchanged from WINDOW 3.1, as well as those calculations that are new to WINDOW 4.0. This report uses the organization of the WINDOW 4.0 program. Results displayed on a WINDOW 4.0 screen are discussed in a section describing that screen. In the conclusion the aspects of the calculation methodmore » currently slated for revision are discussed. A glossary of variables used throughout the report is found in Section 11.« less


The Influence of the loss factor,thickness and flake filler on the sound isolation performance of polyurethane elastomer is studied. The results show that the acoustic isolation performance is improved with the increase of the thickness and loss factor of polyurethane materials under the same frequency. But in the range of low frequency, when the thickness of materials is larger than 40 mm, the sound transmission loss increases very slightly with the variety of thickness. Fillers added in the materials can improve the sound isolation performance of materials. When the content of the filler is between 5%~25% (W/W), it has little effect on the sound isolation performance.


Three capillary tube-suction line heat exchangers (ctslhx's) were tested under steady and quasi-steady conditions over a range of subcooled inlet temperatures and pressures, and mass flows were measured with a coriolis-type meter. Hysteresis was observed; mass flow rate is multivalued and depends on whether the flash point is moving upstream or downstream. Additional experiments were conducted with capillary tube inlet conditions held constant while suction inlet superheat was varied, and the phenomenon was observed again. The same effect was reproduced in an operating refrigerator, affecting its thermodynamic cycle efficiency by 3%. These experiments provide the first evidence of such behavior in diabatic capillary tubes. The implications for both research and design are important. These results may explain much of the scatter in previously published data, but they imply that the value of such data is limited by lack of information about the path along which the steady test conditions were approached. Designers using steady-state models based on equilibrium thermodynamic assumptions must also live with this uncertainty until more is known about metastable behavior and its path-dependence.


The utility model relates to a single-inlet double-outlet hole structure applied to a turbine blade air film cooling technology. The structure comprises a turbine blade, an air film hole inlet, a main cylinder hole and a secondary cylinder hole, wherein the air film hole inlet, the main cylinder hole and the secondary cylinder hole are arranged on the turbine blade; the included angle between the central axis of the main cylinder hole and the wall surface of the turbine blade is 20-60 degrees; the second cylinder hole is arranged on the inner wall of the main cylinder hole and intersects with the main cylinder hole; the diameter of the secondary cylinder hole is smaller than the diameter of the main cylinder hole; the inclined angle between the central axis of the secondary cylinder hole and the surface wall of the turbine blade is 30-90 degrees, which is larger than the inclined angle of the central axis of the main cylinder hole and the wall surface of the turbine blade; the inclined angle (i.e. the azimuth angle of the secondary hole) between the projection of the central axis of the main cylinder and the projection of the central axis of the secondary cylinder on the surface of the turbine blade is 30-90 degrees; and a distance from the intersection point of the axis of the secondary cylinder hole and the axis of the main cylinder hole to the center of an air film inlet is L which is 1.5 times as large as the diameter of the main cylinder hole. The utility model has simple structure, easy processing and good heat insulation effect.


To the best of our knowledge, no previous cases of infestations by Plodia interpunctella larvae have been reported in humans. Plodia interpunctella (Hübner, 1813) (Lepidoptera, Pyralidae), received its common name "the Indian meal moth" from the United States where it was found to be a pest of "Indian corn" or maize. This insect is traced in a wide range of climates in homestored products and food storage facilities around the world. The larvae are general feeders and can be found in grain products, seeds, dried fruit, and dog food. P. interpunctella has proved to be the most economically important pest of processed food. Recent research investigated the potential role as reservoir of infectious agents in microbioma; however, no one reports information on the parasitic role of the species.4,5 Animal infestation has been described in extremely rare cases: P. interpunctella has been reported in Indian ringnecked parakeets and domestic cats by Pinckney et al.6 in Received: 2 January 2023 | Accepted: 8 March 2023


In accordance to the basic principles and major factors of the metallogenic analysis (structural morphostructural,
magmatic and mineralizing), at the territory of the Republic of Macedonia were
determined few major Alpine ore districts: Kratovo-Zletovo, Damjan-Buchim-Borov Dol, Sasa-Toranica,
Pehcevo-Ograzden and Kozuf. All of them are enclosed within the Serbo-Macedonian metallogenetic

The relationship between obstructive sleep apnea (OSA) and gastroesophageal reflux disease (GERD) remains an area of controversy with varying hypotheses. Both disorders negatively impact health-related quality of life and lead to detrimental clinical outcomes. The aim of our study was to determine the association between OSA and GERD.

 We performed a review of the literature across major databases including PubMed/MEDLINE, Embase, and Google Scholar in November 2021. Studies including patients with GERD and OSA were eligible for inclusion. The endpoints were to assess the association between OSA and GERD, the prevalence of OSA in patients with GERD or without GERD, and the prevalence of GERD in patients with or without OSA. Subgroup analyses were performed to determine whether body mass index (BMI), sex, smoking, or alcohol intake affect the degree of association. The total sleep time, sleep efficiency, and apnea hypopnea index (AHI) were compared between OSA patients with or without GERD. Results were pooled together using Reviewer Manager 5.4 software, and heterogeneity was quantified using I2 statistics

 6 studies involving 2950 patients with either GERD or OSA were included in the pooled analysis. Our findings suggest that there was a statistically significant association between GERD and OSA (OR=1.67, 95% CI [1.18, 2.37], P=0.004). The prevalence of GERD was higher in patients with OSA compared to those without OSA (OR=1.63, P=0.001). Conversely, there was no difference in the prevalence of OSA in patients with or without GERD (OR=1.94, P=0.11). Subgroup analysis shows that BMI, sex, smoking, and alcohol intake did not alter the association between GERD and OSA. In patients with OSA, there were no statistically significant differences in the total sleep time, sleep efficiency, and AHI between those with or without GERD. The mean differences were -5.89 minutes (P=0.19), -0.81% (P=0.67), and 0.80 (P=0.83), respectively.

 Our results showed an increased prevalence of GERD is observed in patients with OSA but not vice-versa. However, the presence of GERD does not alter the total sleep time, sleep efficiency, and AHI in patients with OSA. BMI, sex, smoking, and alcohol intake do not seem to affect the strength of this association.


where the index of ' '0 corresponds to the light neutrino flavor, f denotes a charged lepton or quark in the first generation, and P L or R with L R 1 5 =2. It has been shown that the NSIs would be compatible with the oscillation effects along with some new features in various neutrino searches [7–9]. The experimental constraints on NSIs have been studied in Refs. [6,10,11]. In particular, the authors in Ref. [6] also have pointed out that the lepton flavor violating decays of ! 3e, ! e; ee, ! e; M with M or , and the e conversion on nuclei could be induced through one-loop effects and give some stringent constraints on the parameters of " ''0 in Eq. (1). Explicitly, " e and " fP ' ' e; are limited to be less than 10 3 and order of 1, respectively. On the other hand, for the flavor diagonal NSIs in the first two generations, " ee; are constrained by the tree level processes in the low energy scattering experiments and could be limited at the level of O 10 3 in future sin2 W experiments. For the third generation, " is presently bounded to be order of 1 by the LEP experiments, but its future limit can be improved slightly to be O 0:3 [6] from KamLAND [12] and solar neutrino data [13,14]. Note that although the constraints on the parameters of " ' ' e; can be given by the precision measurements on sin2 W at neutrino factories but the bounds can only be O 10 2 [6,15]. In this brief report, we will study two new processes of K !  and D !  in the framework of the NSIs. We will show that the parameters involving neutrino in "uL ''0 could be limited to be less than 10 2 by the rare decay K ! . We will also display the branching ratio of D ! ' '0 could be at the level of 10 8 due to the NSI, which could be accessible to BESIII [16]. We start with the decay of K ! . Since we are not going to deal with CP violation, we will skip the discussion of theCP violating mode ofKL ! 0 , which is nevertheless interesting on its own [17]. It is well known that at the quark level, the effective Hamiltonian for s! d  in the SM is given by [18]

We perform a comprehensive analysis of the Toorop-Feruglio-Hagedorn (TFH) mixing patterns within the family symmetry ∆(96). The general neutrino mass matrix for the TFH mixing and its symmetry properties are investigated. The possible realizations of the TFH mixing in ∆(96) are analyzed in the minimalist approach. We propose two dynamical models which produce the TFH mixing patterns at leading order. The full flavor symmetries are ∆(96)×Z3 ×Z3 and ∆(96)×Z5 ×Z2 respectively. The next to leading order terms introduce corrections of order λc to the three mixing angles in both models. The allowed mixing patterns are studied under the condition that the Klein four subgroups and the cyclic ZN subgroups with N ≥ 3 are preserved in the neutrino and the charged lepton sector respectively. We suggest that the deformed tri-bimaximal mixing is a good leading order approximation to understanding a largish reactor angle. Email: email@example.com


This paper describes the development of a model which quantifies the effects of latency on a player's perceived game quality in the networked first person shooter game Team Fortress 2, in an attempt to replicate and extend previous research done on other games. We conducted a study to measure the subjective quality of gameplay under various induced latency conditions. We determined that latency had a significant effect on a player's perceived quality of the game, yet did not significantly affect player performance. Using these data, we constructed the Team Fortress 2 G-model to predict the mean opinion score of Team Fortress 2 game based on known network conditions.

The Hierarchical Data Format (HDF) is an interesting approach for developing scientific applications where a large amount of data must be stored and accessed. A telemedicine project underway in the State of Santa Catarina (SC), in Brazil, has developed a server called the CyclopsDCMServer, which adopts the HDF for the manipulation of medical images (DICOM). This paper proposes a new approach for the parallel implementation of I/O operations for the medical images stored on this server. This effort was based upon the MPI paradigm that is supported by the version 5 of the HDF. Early experiments indicate that the proposed approach can achieve very good performance when compared to the standard HDF implemented in the CyclopsDCM-Server.

Vapor phase infiltration (VPI) of ZnO into the elastomeric polymer polyisoprene creates an organic-inorganic hybrid material. Inorganic loading and hybrid structure depend upon the initial polymer free volume and the extent of polymer oxidation.


According to the characteristics of chemical composition, the chromium spinel groups derived from three different ultrabasic rock series found in Northwestern China may be divided into six types. The three ultrabasic rock series are situated in different petrogenetic positions belonging to different geotectonic (areas) in this region. The chemical characteristics of the chromium spinel groups may be summarized as follows:1. In the platform area. The rock bodies are predominantly of the ferro-magmatie series, their chromspinels are rich in Al, Fe and Ti, consisting of two types:(1) low-chromium and rich-aluminum type; contents of major oxides (w.t. %): Cr_2O_3 28—34, Al_2O_3 19—35, Fe_2O_3 9—19, FeO 17—28, MgO 5—14.(2) rich-chromium and high-iron type; contents of major oxides (w. t. %): Cr_2O_3 34—43, Al_2O_3 12—24, Fe_2O_3 8—20, FeO 23—35, MgO 3—8.2. In the geosynclinal area. The rock bodies are predominantly of the magnesian mag-matie series; their chromspincls are rich in magnesium and poor in iron, also consisting of two types:(3) rich-chromium and rich-aluminum type; contents of major oxides (w. t. %): Cr_2O_3 34—50, Al_2O_3 14—27, Fe_2O_3 2—10, FeO 13—20, MgO 9—15.(4) high-chromium and low-aluminum type; contents of major oxides (w.t. %): Cr_2O_3 52—65, Al_2O_3 7—15, Fe_2O_3 1—6, FeO 10—19, MgO 10—16.3. In the marginal part of the platform. The rock bodies are predominantly of the calcium-magnesium-ferro magmatic series; chromspinels from them are rich in iron and poor in alumium, consisting of only one type:(5) high-chromium and rich-iron type; contents of major oxides (w.t. %): Cr_2O_3 52—62, Al_2O_3 5—10, Fe_2O_3 4—15, FeO 14—28, MgO 3—12.4. In older upwarded part in the geosynclinal area. The rock bodies are predominantly of the calcium-magnesium-ferro magmatie series; chromspinels arc rich in magnesium and poor in iron, consisting of only one type:(6) rich-chromium and low-aluminum type; contents of major oxides(w. t. %): Cr_2O_3 44—55, Al_2O_3 11—19, Fe_2O_3 1—6, FeO 13—20, MgO 9—14.At the end of this paper, it is suggested that the difference in chemical composition of ore forming chromspinels may be considered an indirect criterion for the appreciations of metallogenetic scales in some ultrabasic bodies. The smaller the difference is, the larger the metallogenetic scale will be.


It is an old saw that science has as its three pillars theory, experiment, and simulation. That we can believe simulation when the three do not agree is a testament to a newfound credence for simulations. Our story concerns widely different simulation and experimental results in a problem of long standing: determination of the rates of chaotic mixing resulting from acceleration across a fluid density discontinuity, namely the classic Rayleigh–Taylor (RT) instability. RT and other interface instabilities [1,9] have long attracted the attention of leading applied mathematicians and physicists, not only Rayleigh and Taylor but also Kelvin, Chandrasekhar, Fermi, Garrett Birkhoff, and John Wheeler, among others. These instabilities occur in flows important both to basic science (supernova explosions) and to technology (inertial confinement fusion). The simplest and most important variable used to describe the mixing rate of fluids of different densities is the dimensionless parameter α, which characterizes the penetration distance h of the lighter fluid (in structures called bubbles) into the heavier fluid: h = α Agt. Here, g is the acceleration force, such as gravity; A is the Atwood number, a dimensionless measure of the contrast in the densities (ρ1 and ρ2) of the two fluids: A = (ρ2 – ρ1)/(ρ2 + ρ1); and t is time. In gravitational free fall, α = 1/2; this value of α describes the penetration of the heavier fluid (in structures called spikes) in the case of an extreme density contrast, A = 1. The formula predicts constant acceleration for the mixing front, as explained below (Theory).

The presence of higher-ploidy cells within Harderian glands (HG) of desert rodents could be explained as an adaptive response to mitigate the effects of photo-oxidative stress. The principally products of HG are porphyrins, pigmentary accretions which interact with the intense luminosity of the Sahara and, then produce reactive oxygen species. Thus, the gland permanently suffers a physiological oxidative stress, with a great number of sings of degeneration, but without compromising the gland integrity. In this work, we used light and transmission electron microscopy to examine the morphological features of cell ploidy in HG of three species of Gerbillidae. Psamomys obesus, Meriones lybicus and Gerbillus tarabuli. The results showed that, the glands of these species are large in size and lobulated. The glandular parenchyma consists of tubuloalveoli surrounding a lumen into which the secretions are discharged. Frequently cells are binucleated and multinucleated. Transmission electron microscopy reveals the presence of secretory cells with conspicuous nuclei and sometimes with micronuclei. Binuclear cells are created by acytokinetic mitosis. No cell membranes within the cytoplasm are observed. Our results provide morphological evidences, that HG of desert rodents employ polyploidy as cellular adaptive response to extreme arid environment.


In this paper, we will compare the performance of several detection algorithm like linear detectors (ZF/MMSE), maximum a posteriori decoder (MAP), sphere detector (SD) and poly-diagonalization and tail-biting trellis detector (PD-ZF/PD-MM) in coded transmission and MIMO frequency selective fading channel environment


The objective: determination of the most optimal method of emptying the uterus in a dead pregnancy in preventing the formation of endometrial pathology in the future. Patients and methods. 90 women aged 18 to 35 years with a history of missed abortion and 40 women in the planning of pregnancy were examined. The main group of Ia — 60 women — a non-developing pregnancy undergoing the traditional method (vacuumm / curettage), group I (30) — vacuum with hysteroscopic quality control of the intervention. Control group II group of 20 women with abortion in the history, II b clinically healthy women in the preparation for maternity. Results. Chronic endometritis was detected in almost 56% of patients with traditional interruption of missed abortion and conventional therapy and 2% in interruption with hysteroscopic control when using imunomodulators. After the abortion with the proposed treatment and the control group, there was no chronic endometritis. In the first group A 50 women (84%) became pregnant, and 11 children were born, 25 patients (84.6%) became pregnant in group I-b, and — 22 (76.3%) gave birth. In group II, 19 patients (96%) became pregnant, 15 women (78%) gave birth. In group II-b, 100% became pregnant, gave birth to 100%. Conclusion. Repeated operatively intrauterine interventions are the guarantee of damage to the receptor component of the endometriumin the future. Pregravidar preparation in women with missed abortion must be of an individual nature with an emphasis on the type of pregnancy and the method of emptying the uterus from the elements of the fetal egg. Predicting future gestational complications in women with an missed abortion in the anamnesis with an individual algorithmof pregravid activities allows the full renewal of reproductive potential.


Let H be a complex Hilbert space. Recall that a bounded linear operator A, on H, is positive if (Ax, x) ≥ 0 (x ∈ H) (so that A = A* necessarily) and positive definite if A is positive and invertible.


Because of the opacity of the atmosphere, x-ray astronomy must be conducted from space. Twenty-five years ago, the first detections of nonsolar x rays were made with simple proportional counters from sounding rockets. Collimated counters aboard rockets and satellites were used to follow up these discoveries, and more recently true x-ray telescopes have been used for the study of x rays from the cosmos. There are now thousands of cataloged x-ray sources ranging from nearby stars to distant quasars. The primary advantages afforded by telescopes for x-ray astronomy are twofold: direct imagery allows finer angular resolution than otherwise possible, and it also betters the sensitivity of the x-ray detectors via the minimization of nonsource background. The primary disadvantages are associated with the necessary grazing-incidence geometry: the effective focal length is limited by the actual telescope length, and the short-wavelength response is, therefore, sharply limited by the shallowness of the grazing angle. Examples are presented of important astronomical results that have been obtained from x-ray telescopes in space. Also presented are conceptual designs (and prototypical test results) from three different types of next-generation telescope for x-ray astronomy.


Replicative DNA polymerases are remarkable molecular machines that carry out DNA synthesis accordingly to the Watson and Crick rules (Guanine pairs with Cytosine and Adenine with Thymidine) with high specificity or fidelity. The biochemical mechanism that dictates polymerase fidelity has its fundaments in the tight active site of replicative polymerases and the shape and size of the Watson‐Crick base pairs. Pre‐steady state kinetic analysis have shown that during polymerase nucleotide addition, the chemical reaction is not the rate limiting step and it was postulated that DNA polymerases suffer a conformational change from an "open" to a "closed" conformation before chemistry which is also the step responsible for their high fidelity. Crystal structures of replicative DNA polymerases demonstrated that the fingers subdomain suffers a large conformational change during catalysis and that this conformational transition aligns the polymerase active site in a proper conformation for catalysis. Recent studies using single molecule techniques and Fluorescence Resonance Energy Transfer analysis also shown that at least in the case of T7 DNA polymerase, the closure of the fingers subdomain is in part the rate limiting step associated with the high fidelity of DNA polymerases, although the overall fidelity of the reaction maybe involves an assemble of chemical steps and several conformational changes. Our current knowledge indicates that the mechanisms of enzyme specificity in DNA replication involve several energy landscapes that maybe correlated with conformational changes and active site assemblies.


The present study was conducted to find out the effect of widowhood rites on the psychosocial well- being of widows in Nadowli District of the Upper West Region (Ghana). The study generally examined three aspects of the well-being of the widows viz psychological, economic and social of widows mainly as a result of the ordeal they go through during widowhood rites. The psychosocial Well-being Scale (PSWS) was used to collect data on eighty widows from Nadowli District. The statistical analysis was done mostly by the t tests. Findings indicated that the younger widows experience higher levels of psychological effects of widowhood than the older widows. In addition, results showed that younger widows tend to experience higher economic setbacks. However, results indicated that there was no difference in social effect widowhood between younger and older widows. Based on this it is recommended that the District Assemblies, Traditional Authorities, NGOs and Gender Based Organizations should come together and abolished some of the widowhood rites that tend to have negative psychosocial well-being on the widows in the Nadowli District.

Methodological approaches to the organization of social and labour relations are systematized. The dynamics of the institutional environment of the labour market and vocational training system interaction in Russia is revealed. The peculiarities of the Russian experience of institutionalization of labour relations in the field of qualifications are shown. Post-industrial development of socio-economic systems, the processes of globalization, the transition of the Russian economy to an innovative model of development, the knowledge economy, the acceleration of scientific and technological progress and other objective challenges have necessitated the development of new human resource management mechanisms. In modern conditions the staff of an organization is considered to be the human capital, i.e. the field for strategic investments, a key factor in ensuring the competitiveness and sustainable development of the country, the region, the sector, the company rather than the costly part of the economy. Currently, one of the main problems of human resourcing for economic growth in the European Union and the Russian Federation is professional and qualification imbalance of supply and demand on the labour market. The National Qualifications System is aimed at solving the problems of linking the labour market with vocational training. Problematic aspects of development of the Russian National Qualifications System are marked.

Beef cows given a diet severely inadequate in phosphorus (P) from 16 weeks before calving maintained appetite until 3-6 weeks after calving when plasma P concentrations were below 1.0 mmol/1 (Bass et al. 1981). The objective of this experiment was to compare the adequacy of ARC (1965) and AFRC (1991) dietary P inputs for ewes in relation to dry matter (DM) intake, plasma P concentration and early lamb growth.Blackface ewes (˃ 3 lambings, n=87, mean liveweight (LW) 53.9, s.d. 5.1kg)) were mated to Border Leicester rams and then randomly allocated to three equal groups according to LW and expected lambing date.


frightened by the thought of networking, the authors provide excellent reasons for why one should engage in such activities. More to the point, the authors provide clear instructions on how to start in these areas. The broad spectrum of this book, which includes looking at mid-career, late career and retirement, its lack of hype and its engaging writing, makes for a great read. Career Q&A is recommended for individuals in professional transition and for institutions with library schools.


Alongside much talk of the dissolution of a nature /culture binary view of the world, there is also, symmetrically, considerable change observed in the performance of relations with non‐humans and the proliferation of hybrids (Latour 1993, Haraway 2003). Through an examination of why and how humans and companion species have begun to live with each other in new ways this paper will challenge (at least) two of those sociological disciplines currently governed by humanist ontologies. It suggests that the sociology of the family and the sociology of housing need a new post‐humanist makeover, for it is increasingly doubtful whether either are exclusively human domains. This is because neither families, households or housing can be thought of any longer as humans among themselves. Companion animals are now found not only in the vast majority of human households / families but their position, role, agency and status has shifted quite profoundly. Using data from a national survey of human–animal relations in Australia it will be shown that companion animals are widely regarded as, and act as, family members and that they occupy housing in profoundly different ways1. The paper argues that this new period of intimacy also ushers in the potential for greater mutual becomings (or co(a)gency to use Michael's term2) as both companion species and their humans (together with their technonatural contexts) explore even more possibilities of co‐presence. The paper concludes with an example of this, taken from the House Rabbit Society: a radical and ever more popular experiment in becomingrabbitbecominghuman (to use a Deleuzian convention)3.


The long-term inclusion of pulses in cropping systems improved the soil fertility, subsequently increased the crop nutrient acquisition and crop productivity. The present research work carried out during 2017-18 at research farm of Tirhut College of Agriculture, Dholi, Muzaffarpur. In the college premises, the various types of types of cropping pattern has been adopted on same piece of land since last more than five years with normal cultivation practices. Soil samples were collected from each treatment (cropping system) at harvesting of crops after completion of one cropping cycle for the analysis of soil Physico-chemical properties. The lowest soil pH exhibited in rice-wheat cropping system followed by pigeon pea cropping system might be attributed to submergence of soil during rice cultivation and greater amount of leaf litters fall throughout crop life cycle in pigeonpea field. The lower value of bulk density (1.21 Mg m-3) and (1.24 Mg m-3) was recorded with mustard mungbean and pigeon pea cropping system. The reduction in bulk density may be attributed to the higher soil organic carbon due to more addition of roots and plant biomass as compared to the fallow land. The variability in Cation Exchange Capacity was ranged from 16.66 to 28.62 (Cmol (P+) kg-1). Mean weight diameter in different treatment varied from 2.51mm to 4.49mm and the highest MWD was recorded in pigeonpea cropping system whereas; the lowest was noticed in fallow lands.

Combined with the H.264/AVC video encoding standard, a new digital video watermarking technology - zero watermarking technology was proposed in the paper. It breaks traditional idea of digital watermarking technique; the important characteristics of video data were used to construct the watermark information. In this paper we construct zero watermark information based on the characteristics of DCT quantization coefficients by intra-prediction. The algorithm is not only real-time but also simple and efficient. Experimental results show that the constructed watermark information had ability of unique identification the host media and robustness against a variety of tampering attacks. And it also can reduce the impact of interpretation attacks by introducing the time-stamp mechanism.


This study was conducted to identify reproducibility, repeatability, and specificity and to establish the evaluation basis through the analytical performance test of the pancreatic cancer microRNA (miRNA) diagnosis chip manufactured at the "Integrated Analysis of Next-Generation Bio-Data" in June 2016. There were 16 selected markers manufactured to be installed in the miRNA diagnosis chip exclusively for pancreatic cancer and used for analytical performance tests for the chip itself. Three analytical performance tests were performed (reproducibility, repeatability, and specificity). For the reproducibility test, the same subject had two test sessions repeated three times per each session. For repeatability analysis, two different subjects had two test sessions repeated three times per each session. Analytical specificity was analyzed by using hierarchical clustering analysis results, comparing the results of two repeated tests of normal miRNA, and the results of six repeated tests of patient group miRNA. As a result of analytical performance tests, coefficient of variance values of reproducibility and repeatability were 10 % or below, and patient groups with pancreatic cancer were significantly divided from normal groups obviously different by hierarchical clustering analysis results. Such tests confirmed that the miRNA diagnosis chip of pancreatic cancer, constructed with 16 markers, is quite suitable.


The compound [Pt3Au(µ-CO)3{P(C6H11)3}4] PF6 has been synthesised from [Pt3(µ-CO)3{P(C6H11)3}3] and [AuCl{P(C6H11)3}] in the presence of TIPF6. It reacts with SO2 to give a tetrahedral platinum–gold cluster compound [Pt3Au(µ-CO)2(µ-SO2){P(C6H11)3}4] PF6(1) in which one of the CO ligands of the starting material has been replaced by SO2. Compound (1) crystallises in the orthorhombic space group Pn21a with four formula units in a cell of dimensions a= 18.671(4), b= 19.618(3), and c= 28.162(4)A. The compound [Pt3(µ-SO2)3{P(C6H11)3}3] reacts with [AuCl{P(C6H4F-p)3}] to give the tetrahedral platinum–gold cluster compound [Pt3Au(µ-SO2)2(µ-Cl){P(C6H11)3}3{P(C6H4F-p)3}](2) in which one of the SO2ligands of the starting triangulo-cluster has been replaced by a bridging chloride. Compound (2) crystallises in the monoclinic space group P21/n with four formula units in a cell of dimensions a= 25.490(4), b= 25.855(6), c= 13.819(4)A, and β= 96.98(2)°. The bonded bridging ligand atoms are approximately coplanar with the metal triangles whilst the metal–phosphine bonds point towards the centre of the metal tetrahedron. N.m.r. studies, 31P-{1H} and 195Pt-{1H}, suggest that the solid-state structures are retained in solution for both compounds. The reaction of [Pt3(µ-SO2)3{P(C6H11)3}3] with [AuCl{P(C6H11)3}] in the presence of TIPF6gives [Pt3Au(µ-SO2)3{P(C6H11)3}4] PF6 which may be converted into (1) by reaction with CO. The compound [Pt3(µ-SO2)3{P(C6H11)3}3] reacts with [AuCl{P(C6H4F-p)3}] to give [Pt3Au(µ-SO2)3{P(C6H11)3}3{P(C6H4F-p)3}] PF6 which may be converted into (2) with NMe4Cl. The compound [Pt3Au(µ-SO2)3{P(C6H11)3}3{P(C6H4F-p)3}] PF6 and its chloride-bridged derivative (2) represent the first examples of compounds formed where [Au(PR3)]+ and [AuCl(PR3)] have been added to the same cluster compound. These studies indicate the occurrence of 54- and 56-electron tetrahedral Pt3Au clusters analogous to the 42- and 44-electron triangular parent clusters.


Bush's foreign policy in the Middle East has generated increased anger in the region. The U. S. war against Iraq has sharply increased the level of anti-Americanism in regional terms. That is not to say that anti-Americanism was caused by the events following 9/11. Anti-Americanism is a result of attitudes and perceptions toward what many Arabs and Muslims call the "anti-Arab and Muslim" foreign policy, especially in regard to the Arab-Israeli conflict, that has existed over a longer period of time. Of course, the Bush Administration is aware of anti-Americanism in the Arab and Islamic world and has admitted that it has reached an unprecedented level. This study attempts to understand the debates over U. S. foreign policy in the Middle East from a Middle Eastern perspective. Mainly it is a case study of the Saudi perspective. It aims to find whether the conduct of U. S. policy has exacerbated the discontent and radicalism which underpins the actions of terrorist groups. Of the Saudi elites interviewed for this study, 90% believe that U. S. foreign policy has contributed to the growth of terrorism. Most of the participants (90.5%) agreed that U. S. support for Israel is the main reason for anti-Americanism.

Toxoid The exotoxin of the staphylococcuis, which is lethal if injected in the crude state, may be robbed of its dangerous properties, but allowed to retain its useful immunizing antigenic properties, by incubation for several days after the addition of a small percentage of formalin. The product thus obtained is known as toxoid, and it has been used in the treatment of chronic staphylococcal infections. By a series of graded injections it is possible to increase the amount of circulating antitoxin in the blood of human beings and animals even to twenty times the original titre. This increase in antitoxin is accompanied by immunity to infection in animals, and by improvement in the clinical condition of humans in a fair percentage of cases.

The notion of separatedness degrees of -fuzzy subsets is introduced in -fuzzy topological spaces by means of -fuzzy closure operators. Furthermore, the notion of connectedness degrees of -fuzzy subsets is introduced. Many properties of connectedness in general topology are generalized to -fuzzy topological spaces.


Renal disease is a common problem in working dogs. While a good history, clinical examination, urine analysis, haematology and blood chemistry are useful in the demonstration of renal disease, they are of relatively little value in describing the nature of the disease that is present. In order to establish a diagnosis and a rational therapeutic approach, microscopic evaluation of renal tissue is considered to be essential. A number of techniques have been described for the collection of renal tissue, including material collected from nephrotomy during laparotomy, or by the use of a variety of biopsy needles. This paper will describe an approach to renal wedge biopsy using a paracostal approach, which provides a better sample than the use of biopsy needles, and reduces the trauma and risks associated with laparotomy. The technique will be illustrated, and the indications for and dangers of renal wedge biopsy discussed.


In this paper, based on the general theory of thin-walled members, the general formula of the critical force to axial uniformly compressed column is derived. Then, it is compared with the result of groovy method. The P_(cr)-λ curve is plotted and studied, the rule shown by the curve and the characteristic of rotation center triangle is revealed. The general formula is the base of the study on axial compressed column and eccentrically compressed column in the general theory. The P_(cr)-λ curve and the rotation center triangle are very important to the succeeding study.


We study the problem of clustering data objects whose locations are uncertain. A data object is represented by an uncertainty region over which a probability density function (pdf) is defined. One method to cluster uncertain objects of this sort is to apply the UK-means algorithm, which is based on the traditional K-means algorithm. In UK-means, an object is assigned to the cluster whose representative has the smallest expected distance to the object. For arbitrary pdf, calculating the expected distance between an object and a cluster representative requires expensive integration computation. We study various pruning methods to avoid such expensive expected distance calculation.


The problem of designing robust controllers and observers for a class of linear composite sys-tems with structural uncertainties is investigated in this paper. A method is given to design decentralized con-trollers and decentralized observers. The state feedback gain matrix and observer gain matrix are obtained from two Riccati equations,respectively.


There is a general challenge offered to the field of engineering economics by the introduction of advanced manufacturing systems. Typically, the traditional approaches do not account for the significant intangible benefits offered by cellular manufacturing systems. In this paper, an attempt has been made to overcome the above-mentioned deficiencies by presenting two multi-attribute decision models – analytical hierarchy process and performance value analysis – for the justification of CMS. The usefulness of the proposed models is demonstrated through a case situation.


The aim of this paper is twofold. First, it answers the question of why Plato is the only philosopher in antiquity that urges that the entire community must hold the same, right beliefs about the divine. Such a position, as I argue in the present work, stands between skepticism and secularism. Second, the present work shows that there is no justification for attributing skeptical doubts on artistic value in poetry to Plato. Indeed, as I emphasize by means of a detailed textual analysis, Plato's attitude toward religious beliefs concurs with Plato's arguments against poetry in Republic II and III.


The detection and the measurement of CP violation in the decays of B hadrons will require the accumulation of large numbers of B decays in particular exclusive modes. The potential of beauty hadroproduction experiments for obtaining these large data samples is examined in the context of various trigger and analysis strategies. The possibilities for doing such experiments at present hadron machines is compared with the potential for such experiments at the SSC. 3 refs., 3 figs., 4 tabs.


It is well known that highly volatile control laws, while theoretically optimal for certain systems, are undesirable from an engineering perspective, being generally deleterious to the controlled system. In this article we are concerned with the temporal volatility of the control process of the regulator in discrete time Linear Quadratic Regulators (LQRs). Our investigation in this paper unearths a surprising connection between the cost functional which an LQR is tasked with minimizing and the temporal variations of its control laws.
We first show that optimally controlling the system always implies high levels of control volatility, i.e., it is impossible to reduce volatility in the optimal control process without sacrificing cost. We also show that, akin to communication systems, every LQR has a $Capacity~Region$ associated with it, that dictates and quantifies how much cost is achievable at a given level of control volatility. This additionally establishes the fact that no admissible control policy can simultaneously achieve low volatility and low cost. We then employ this analysis to explain the phenomenon of temporal price volatility frequently observed in deregulated electricity markets.


The Malaysian Government initiated the Digital Malaysia (DM) program to advance the country towards a developed digital economy by 2020. Electronic Book or e-Book has been used to facilitate the learning process in formal education since 2009 in Malaysia. The content and media used in e-Book has transformed traditional classroom to a digital learning environment. This study aims to investigate the quality of e-Book applications in facilitating classroom learning based on the ISO 25010 standard. A survey of 37 primary schools in the district of Kemaman in Terengganu was carried out involving 200 teachers. Results indicate that e-Book applications are perceived as usable, reliable, functional, and efficient in supporting the learning process. There is room for improvements through increasing the number functions provided and upgrading the hardware specifications. Results also suggested that e-Book is in the right direction in meeting its goal and objectives.


In this second of two articles (designated I and II), the bilinear transformation method is used to obtain stationary periodic solutions of the partially integrable regularized long‐wave (RLW) equation. These solutions are expressed in terms of Riemann theta functions, and this approach leads to a new and compact expression for the important dispersion relation. The periodic solution (or cnoidal wave) can be represented as an infinite sum of sech2 ''solitary waves'': this remarkable property may be interpreted in the context of a nonlinear superposition principle. The RLW cnoidal wave approximates to a sinusoidal wave and a solitary wave in the limits of small and large amplitudes, respectively. Analytic approximations and error estimates are given which shed light on the character of the cnoidal wave in the different parameter regimes. Similar results are presented in brief for the related RLW Boussinesq (RLWB) equation.

ABSTRACT This study employed multiple regression analysis to examine the relationship between global writing quality (holistic scores) and lower level analytic measures of writing, with a focus on cohesive indices. The subjects were 9-year-old English-speaking children who participated in either a story free-writing condition or a story rewriting condition. The results showed that both cohesive indices and lower level writing measures (type-token ratios, mean length of utterances in morphemes, composition length, etc.) each accounted for a significant amount of the variance in holistic scores. The story rewriting procedure proved to facilitate the children's writing processes and, hence, resulted in higher quality writing (in terms of both global writing quality and text cohesion) than the story free-writing condition.


Propargylations of 1,3-diketones using 3-sulfanyl and 3-selanylpropargyl alcohols 1 in MeNO(2)-H(2)O gave alkynyl ketones 2a-m, 2o-v and 6,7-dihydro-5H-cyclohexa[b]pyran-5-ones 3k-n. With some bases, the useful propargylated 1,3-diketones underwent intramolecular cyclization to give 6,7-dihydro-5H-benzofuran-4-ones 4a-i or 4,5,6,7-tetrahydrobenzofurans 5p, 6p-v.


Updating state transition of a state portion of each control unit is activated state from a stopped state, or the transition from the active state to the stopped state, the first update information stored in the storage unit. Second power supply section generates power by a radio wave received by the antenna sensing portion. Information acquisition section is driven from the power of the second power supply unit, thus providing a second information indicating whether the first power supply portion supplying power, and acquires the first information from the storage unit, to transmit the acquired first information, second information to controlling device. 1 based on the information transmitted from the information terminal apparatus acquiring unit, the second failure information determination unit determines the terminal device.


Iron(II) complexes exhibiting thermal spin crossover may be converted from the 1A1 low-spin (LS) state to the 5T2 high-spin (HS) state by irradiation with green light (light-induced excited spin-state trapping, LIESST). The lifetime of the metastable LIESST state may be sufficiently long for X-ray diffraction study. The lattice parameters of a single crystal of [Fe(ptz)6](BF4)2 (ptz = propyltetrazole) were measured between 300 and 10 K, while the crystal changed from the HS to the LS state near 135 K. Using the green light (514 nm) of an argon-ion laser, the crystal was quantitatively converted to the metastable LIESST state at 10 K; its lattice parameters were measured up to 50 K, at which point the LIESST state begins to decay on a minute timescale. The change of the lattice parameters can be interpreted by a superposition of a normal temperature dependence, for which the isostructural zinc compound served as a reference, and an almost temperature-independent part which is proportional to the fraction of molecules in the HS state.


The aim of this study was to provide baseline data and fill an outstanding knowledge gap in our understanding of factors affecting the invasiveness of the Ponto-Caspian gobiid Neogobius fluviatilis. To this end, the life history traits (as somatic growth and reproduction) of N. fluviatilis were studied in three natural freshwater lakes in its native range. These populations were characterised by slow somatic growth rates, being the slowest reported across all the native and non-native ranges of N. fluviatilis. Ages were recorded to 7 years. Across the three lakes, there was considerable variability in sex ratios and reproductive traits (including length at maturity and fecundity at length and age), revealing considerable interpopulation variability. These data suggest that N. fluviatilis has considerable plasticity in the expression of its life history traits, with this plasticity argued as a key factor in facilitating the ability of N. fluviatilis to establish and invade new waters following introductions.


This paper aims at developing mutual statistical descriptions of images in a visual sensor network. A two-dimensional Gaussian scale mixture (GSM) model is proposed to describe the joint distribution of wavelet coefficients in the same subband of two different images. This model is tested on two image databases, and it is shown that the proposed model always achieves a smaller divergence from the empirical distribution than a (jointly) Gaussian model. The GSM model is then extended to blocks of wavelet coefficients in the same subband and scale of non-overlapping images. A new denoising algorithm is devised that uses this model and achieves better performance than denoising based on marginal models.
