Thermal spreading/constriction resistance is an important phenomenon where a heat source/sink is in contact with a body. Thermal spreading resistance associated with heat transfer through the mechanical contact of two bodies occurs in a wide range of applications. The real contact area forms typically a few percent of the nominal contact area. In practice, due to random nature of contacting surfaces, the actual shape of microcontacts is unknown; therefore, it is advantageous to have a model applicable to any arbitrary-shape heat source. Starting from a half-space representation of the heat transfer problem, a compact model is proposed based on the generalization of the analytical solution of the spreading resistance of an elliptical source on a half-space. Using a "bottom-up" approach, unified relations are found that allow accurate calculation of spreading resistance over a wide variety of heat source shapes under both isoflux and isothermal conditions.


It investigates the development of language and literacy in children of "Republica de Colombia" School, since it has witnessed the difficulty in pronunciation of language, and therefore this affects the child writing in the future. They have no interest in listening to stories, was not perfmed exercises in the classroom there was little stimulation to develop language skills. The aim of the research was to determine whether the development of language influences in literacy, pictograms, stories, nursery rhymes, and oral exercises can apply the teacher in and outside the classroom because through these recreational activities playful skills language playful in children by creating situations. The methodology used in the project is qualitative and quantitative because it is realistic, explicit rules, and statistics was done which allow us to deduce data obtained from the research was conducted. It has an impact of social action showing a lot of children with problems in the development of their language being a problem that can solve long or short term. The language is very essential in the development of children both at school and social environment so that they can manage in the future, the child's language is increased as grows, but some children have not achieved by low income will not able to receive adequate stimulation for language development. One way of solution to the problem is to provide adequate stimulation for children to develop their language to develop within the educational and social environment by publicizing how to express their ideas, thoughts, and feelings through language.


We develop the method of averaging in Clifford (geometric) algebras suggested by the author in previous papers. We consider operators constructed using two different sets of anticommuting elements of real or complexified Clifford algebras. These operators generalize Reynolds operators from the representation theory of finite groups. We prove a number of new properties of these operators. Using the generalized Reynolds operators, we give a complete proof of the generalization of Pauli's theorem to the case of Clifford algebras of arbitrary dimension. The results can be used in geometry, physics, engineering, computer science, and other applications.


Analysis of the issue in the field of distance education showed that currently there is a need for specific cohort in educational services, especially for children with disabilities. This need in the market of educational services creates supply, which manifests itself in the occurrence and development of educational institutions that conduct distance learning, guided primarily by empirical experience, in the absence of sufficient science-based models and technologies for distance education. It becomes evident that the successful development of the system of distance education can be accomplished only if didactically reasonable use of means of new information technologies, which are the material basis of the system of distance learning. Information technology tools quantitatively and qualitatively are constantly evolving and improving, providing a rich set of potential learning opportunities. After reviewing the relevant literature and practice, we can say about the inadequacy of the currently developed distance learning courses that meet modern requirements. Modernization of Russian education is an innovative process of transforming the entire education system, aimed at maximum satisfaction of learning needs of students on a wide range of occupations, education levels, educational institutions, information and educational resources. The education should give the desired effect, regardless of location, as both student and educational resource or service, it needs to be carried out using the most modern information and telecommunication technologies. The result of this process is the achievement of new quality for Russian education that is determined, in the first place, its conformity with current and future demands of modern life.


YARS2 variants have previously been described in patients with myopathy, lactic acidosis and sideroblastic anemia 2 (MLASA2). YARS2 encodes the mitochondrial tyrosyl-tRNA synthetase, which is responsible for conjugating tyrosine to its cognate mt-tRNA for mitochondrial protein synthesis. Here we describe 14 individuals from 11 families presenting with sideroblastic anemia and YARS2 variants that we identified using a sideroblastic anemia gene panel or exome sequencing. The phenotype of these patients ranged from MLASA to isolated congenital sideroblastic anemia. As in previous cases, inter- and intra-familial phenotypic variability was observed, however, this report includes the first cases with isolated sideroblastic anemia and patients with biallelic YARS2 variants that have no clinically ascertainable phenotype. We identified ten novel YARS2 variants and three previously reported variants. In vitro amino-acylation assays of five novel missense variants showed that three had less effect on the catalytic activity of YARS2 than the most commonly reported variant, p.(Phe52Leu), associated with MLASA2, which may explain the milder phenotypes in patients with these variants. However, the other two missense variants had a more severe effect on YARS2 catalytic efficiency. Several patients carried the common YARS2 c.572 G>T, p.(Gly191Val) variant (minor allele frequency =0.1259) in trans with a rare deleterious YARS2 variant. We have previously shown that the p.(Gly191Val) variant reduces YARS2 catalytic activity. Consequently, we suggest that biallelic YARS2 variants, including severe loss-of-function alleles in trans of the common p.(Gly191Val) variant, should be considered as a cause of isolated congenital sideroblastic anemia, as well as the MLASA syndromic phenotype.


In this paper, we investigate the valuation of dynamic fund protections under the assumption that the market value of the basic fund and the protection level follow regime-switching processes with jumps. The price of the dynamic fund protection (DFP) is associated with the Laplace transform of the first passage time. We derive the explicit formula for the Laplace transform of the DFP under the regime-switching, hyper-exponential jump-diffusion process. By using the Gaver-Stehfest algorithm, we present some numerical results for the price of the DFP.


Pharmacological activity of a series of new amino derivatives of dehydroabietic acid has been studied. 12-N,N-Diethylaminoacetyl-8,11,13-abietatrien-18-oate hydrochloride produces a calming effect, shows a pronounced anxiolytic activity, and exhibits antipyretic action comparable to that of the reference drug (analgin).


The influence of large doses of acetazolamide upon the regulation of the CSF pH in normocapnia and hypercapnia was studied in non-nephrectomized and nephrectomized rats. In non-nephrectomized animals studied over a 24 h period there was a decrease in the CSF HCO-3 concentration of 10 mEq/kg. Since the CSF acidosis was far in excess of that usually encountered with a comparable degree of plasma acidosis, the results indicate that acetazolamide inhibited a carbonic anhydrase-dependent transport of H+or HCO-3 between CSF and plasma. However, when the fall in plasma [HCO-3] was prevented by means of a bilateral nephrectomy, acetazolamide did not affect the CSF pH under normocapnic conditions, nor did it retard the accumulation of HCO-3 in the CSF during hypercapnic conditions. The results do not support any of the existing hypotheses which try to explain the regulation of the CSF pH in both respiratory and non-respiratory acid-base disturbances in terms of a common mechanism.


This study of art galleries in the Peoples' Republic of China (PRC) uses a political economy approach to examine the contours of the art world and the art market. A Chinese art market based on the Western and Japanese models was created in the early twentieth century, but was abolished in 1949 when the PRC, under Chairman Mao, adopted a socialist framing model on a national scale. Breaking out of this totalizing frame was difficult despite the adoption of market socialism in 1979. The decade between 1979 and 1989 witnessed rapid surges of creativity, which were brought to a full stop by the 1989 Tiananmen Square massacre. In 1992, however, the national policy of rapid growth gave the cultural industry a sharp nudge. Since the mid‐1990s, two trends in the art world have emerged: a collaborative framework for developing contemporary PRC art (including commercial art) for both the internal and external markets; domestic art as a commentary on changing social and cultural values.


The aim of our paper is to empirically estimate the direction and magnitude of technological spillovers from FDI using a plant level dataset of Romanian firms for the period 1999-2007. We use the Levinsohn Petrin (2003) methodology in order to estimate total factor productivity and compute several measures of spillover effect based on time varying Input-Output tables. We find local suppliers to benefit from positive backward spillovers while local clients are negatively affected by forward spillovers. Using several measure of absorptive capacity like human capital or R&D does not change our results. On the other hand, a large technological gap favors the capture of technological spillovers. Labor mobility is the only significant horizontal spillovers. We also find that labor mobility changes direction according to different human capital levels. We finally show that local firms buying inputs from FDI suppliers are negatively affected by a second order vertical spillover.

Patients with mutant IDH1 gliomas survive ~3.8 year longer than patients harboring wildtype IDH1 glioma, irrespective of histology or genetic lesions, making mutant IDH1 an essential prognostic indicator. Mutant IDH1 gliomas are highly infiltrative with a high incidence of relapse. We are studying a low grade glioma subtype, genetically characterized by inactivating mutations in α-thalassemia/mental retardation syndrome X-linked (ATRX) gene, TP53 and gain of function mutations in isocitrate dehyrdogenase 1 (mIDH1). Mutation in IDH1 converts α-ketoglutrate (αKG) to 2-hydroxyglutarate (2HG), an oncometabolite that inhibits histone and DNA demethylases, leading to a hypermethylated tumor phenotype [1]. This leads to epigenetic reprograming of the tumor transcriptome. The role of 2HG as an immune regulator in the mIDH1 glioma tumor microenvironment remains to be elucidated. Herein, we investigate whether 2HG produced by mIDH1 glioma in the tumor microenvironment mediating antitumor immunity. We used mIDH1 inhibitor AGI-5198 to abrogate the neomorphic enzymatic activity of IDH1R132H in a transplantable mIDH1 glioma mouse model. Animals were implanted with mIDH1 tumor neurospheres and they were systemically administered with AGI-5198. Our results indicate that pharmacological inhibition of IDH1R132H enzymatic function significantly prolongs the median survival (MS) of mIDH1 glioma bearing mice (~1.5-fold vs controls); eliciting strong antitumor activity, eradicating 40% of the established mIDH1 gliomas. Our results also demonstrate that antitumor immunity induced by 2HG inhibition is enhanced when combined with standard of care (temozolomide and radiation) and anti-PDL1 immune checkpoint blockade. In addition, when the long-term survivors (>90 days) were rechallenged with mIDH1 tumor cells in the contralateral hemisphere, without further treatment, all the mice remained tumor free, indicating the development of anti-glioma immunological memory. Collectively, these findings support the clinical testing of AGI-5198 as an adjuvant therapy and a novel immunotherapeutic strategy for treating patients with mIDH1 glioma.


There are two fundamental approaches to the problem of legal interpretation, one concentrating on the use of abstract concepts and their analysis by pure logic, and the second concentrating on policy considerations which underlie legal rules and the function they are to serve. It cannot be denied that the "conceptual" method appears, at first glance, more "scientific" and precise as compared with the "functional" method, but in real fact it does not always ensure certainty and predictability. In many cases, the use of vague general concepts may lead to unexpected results, because the actual construction given to these concepts by the courts may vary according to the concrete facts involved (e.g. the concept of "proximity" in the law of attempt). But even if, generally speaking, the "conceptual" method achieves a higher standard of certainty than the other method mentioned, one cannot overlook the fact that in some cases the use of the "conceptual" method may lead to injustice, or at least to a failure to achieve the social aims the legislator had in mind. The importance of certainty and predictability, especially in criminal matters, is beyond dispute, but the weight given to this value in relation to other social values may differ from society to society and from time to time.


In the absence of suitable single crystals, the problem of determining the connectivity pattern of the title compound (and of its phenyl analogue), i.e. that of discriminating between two markedly different stereoisomers, has been solved by the powder diffraction technique. The structure was solved by ab initio XRPD methods and refined by the Rietveld technique down to Rwp = 0.123, Rp = 0.087, and RF = 0.061 for 5000 data points (847 reflections) collected in the 8 < 2 θ < 108° range. The diffraction results have been cross-validated by steric energy computations within the field of the given crystal lattice.


In a recent issue of PNAS, Adams et al. (1) project a 5-fold increase in the frequency of tree die-off in pinon (Pinus edulis) under drought in the southwestern United States due to elevated temperature alone. Their study is based on 10 excavated individuals grown in containers and exposed to complete drought under either ambient or elevated temperature (+4.3 °C, 5 replicates). Trees experiencing higher temperatures died 7 weeks earlier than control trees. The authors explain this by a trend to increased respiration under warmer conditions resulting in earlier carbon starvation. In addition to the recent letter by Sala (2) pointing out that there is no direct evidence for carbon starvation as a cause of tree death to date, we are concerned with (i) the methods used to arrive at Adams et al.'s (1) interpretation and (ii) the way tree die-off is extrapolated to large spatio-temporal scales from their small sample size.

GRACE-FO carries a Laser Ranging Interferometer (LRI) as a technology demonstration to provide measurements of inter-satellite range changes. This additional measurement technology provides supplementary observations, which improve the reliability of the range rate measurements and allow for a cross-instrument diagnostics and calibration with the K-band ranging (KBR) system.

We present a two-step approach used for LRI1B data calibration within the ITSG-Grace2018 scheme, which is compatible with the entire v04 release timespan. The aim of this study is to mitigate the remaining systematics due to the LRI datation time offset and LRI scale factor. We discuss the implementation of calibration parameters and the contribution of the calibration approach to the overall accuracy of gravity field solutions.

Structures located in seismic zones require significant ductility. It is valuable to investigate the relationship between bond stress and slip displacement. Cyclic loading can result in severe deterioration in the bond between reinforcing steel bar and the surrounding concrete, especially when the reinforcement is corroded. Tests have been carried out under cyclic loading to investigate the bond stress–slip response of corroded reinforcement with concrete. The results showed that the rate of bond reduction had been lowered by corrosion. Bond reduction was significantly less for deformed bars than for smooth bars during the first loading cycle, but the difference was substantially decreased after ten cycles. Bond reduction was more substantial for unconfined steel bars than for confined ones. The relatively high level of corrosion caused reduction in bond primarily in the initial five cycles and the effect of corrosion was decreased with the number of loading cycles. It was also demonstrated that the shape...


Hydrogels have been a topic of extensive research because of their unique bulk and surface properties. They play a vital role in development of controlled release drug delivery systems. Polysulfone hydrogels are hydrophilic porous materials, which provide the advantage of biocompatibility and effective orientation of biomolecule in the design of the novel biosensors [1-2]. Polysulfone hydrogels may be prepared as water swellable powders or drop cast as thin films on screen printed carbon electrodes (SPCE). Polysulfone hydrogels produce electroactive thin films, characterized by 2 well resolved redox peaks, with a formal potential of 0.0867 V and diffusion coefficient in aqueous medium of 9.06e-9 Cm2/s. In this paper we report on the initial speciation studies and analytical performance of Selenium and Vanadium at the hydrogel electrodes, as evaluated by using cyclic voltammetry in a range of -0.7 V to +0.0 V versus Ag/AgCl. The morphology, adsorption and thin film integrity was evaluated using High resolution scanning electron microscopy (HR-SEM), UV-Vis and Raman spectroscopy.


Standard decrement curves in use for a number of years in the calculation of power system voltages and currents under fault conditions now have been revised and are presented herewith. Their use enables the determination of the magnitudes of voltages and currents for various intervals of time subsequent to the occurrence of a fault.


Abstract : The focus of this thesis is to use and leverage the strengths of dynamic computer program analysis methodologies in software engineering testing and debugging such as program behavior modeling and event grammars to automate the building and analysis of combat simulations. An original high level language METALS (Meta-Language for Combat Simulations) and its associated parser and C++ code generator were designed to reduce the amount of time and developmental efforts needed to build sophisticated real world combat simulations. A C++ simulation of the Navy's current mine avoidance problem in littoral waters was generated using high level METALS description in the thesis as a demonstration. The software tools that were developed will allow users to focus their attention and efforts in the problem domain while sparing them to a considerable extent the rigors of detailed implementation.


This paper looks at two variants of slipping that exist in precision roller-band mechanisms (PRBM), such as a Rolamite-type mechanism (geometric and springy slipping). The rollers are wrapped by a flexible band in the mechanisms and contacted between themselves only through a flexible band, the ends of which are attached to the directing planes of the rolamite type mechanism (RTM). In the PRBM there is geometric sliding, the value of which is influenced by the thickness of the flexible band. Compensation of the geometric sliding can be achieved by introducing additional band-wrapping rollers, the direction of which is opposite to the main band's direction. The influence of the flexible band's free ends on the accuracy of the positioning of the mechanism is reviewed. The calculation scheme of the mechanism for the measurement and calculation of springy slipping of RTM units is presented and described by equations. It is established that the springy slipping in the RTM is connected to the strain of the free band's pieces from the resistance forces of motion. The value of springy slipping directly depends on the resistance force, the amplitude of motion and the value of the coordinate of the swinging centre. The scheme of a compensator of the springy slipping is presented. The calculation relations permitting us to define the parameters of spring-compensator, eliminating springy slipping, are deduced.


Dimethylsiloxane (DMS)-bisphenol-A carbonate (BPAC) alternating block copolymers having overall compositions ranging from 25 to 83 wt-% siloxane have been examined as films spread at the air-water interface. At low surface pressure, the siloxane blocks appear to spread completely, while the BPAC segments are not located in the interface; the area occupied at low pressure is directly proportional to the siloxane content. At π = 6–8 dynes/cm, a rearrangement substantially identical to that observed with homopoly-DMS films occurs. At areas of 0.2–0.4 m2/mg, fairly stable films persist (π up to > 12 dynes/cm), and the area requirement for these films depends on the overall composition, but we do not yet know the molecular configurations involved in this region. The mono-layer properties may provide useful characterization data for copolymers of this type, as well as providing insight into their behavior at other interfaces.


The injector for the National Synchrotron Light Source II (NSLS-II) storage ring consists of a 3 GeV booster synchrotron and a 200 MeV S-band linac. The linac was designed to produce either a single bunch with a charge of 0.5 nC of electrons or a train of bunches up to 300 ns long containing a total charge of 15 nC. The booster was designed to accelerate up to 15 nC each cycle in a train of bunches up to 300 ns long. Linac commissioning was completed in April 2012. Booster commissioning was started in November 2013 and completed in March 2014. All of the significant design goals were satisfied including beam emittance, energy spread, and transport efficiency. While the maximum booster charge accelerated was only 10 nC, this has proven to be more than sufficient for storage ring commissioning and operation. The injector has operated reliably during storage ring operation since then. Results will be presented showing measurements of linac and booster operating parameters achieved during commissioning and initial operation. Operating experience and reliability during the first year of NSLS-II operation will be discussed.


OBJECTIVE
The primary aim of this study was to determine the effects of spouse or significant other solicitous responses on morphine equivalent dose among adults with chronic pain.

DESIGN
Retrospective design.

SETTING
Multidisciplinary pain rehabilitation center.

PATIENTS
The cohort included 466 consecutively admitted patients who had a spouse or significant other and were using daily opioids. Intervention. Three-week outpatient pain rehabilitation program.

OUTCOME MEASURES
Solicitous subscale of the Multidimensional Pain Inventory and morphine equivalent dose upon admission.

RESULTS
The mean solicitous subscale score and morphine equivalent dose were 49.8 (standard deviation [SD] = 8.7) and 118mg/day (SD =149), respectively. Univariate linear regression analysis showed that greater subscale scores were associated with greater doses of opioids (P = 0.007). In a multivariate model adjusted for age, sex, ethnicity, years of education, employment status, pain duration, depression, and pain severity, the association retained significance (P = 0.007).

CONCLUSIONS
These findings suggest solicitous responses from a spouse or significant other may have an important influence on opioid dose among adults with chronic pain.


Usu volcano is one of the most active volcanoes in Japan, which is in the Shikotsu-Toya National Park, Hokkaido. There have been eight recorded eruptions since AD 1663 at a relatively short time interval (ca. 30-50 y). We here focus on the most recent AD 2000 eruption to understand the present conditions of the Usu magma-feeding system, which is important to prepare for the next eruption. The AD 2000 eruption started with a phreatomagmatic (small phreatoplinian) eruption, producing dacitic pumice (Us-2000pm; Tomiya et al., 2001), followed by many small phreatic explosions. Petrographical studies (Tomiya and Miyagi, 2002; Tomiya and Takahashi, 2005) and melting experiments under high pressure and temperature conditions (Tomiya, 2002; Suzuki et al., 2007) of the AD 2000 volcanic products (Us-2000pm) have been performed. However, petrological constraints are still limited. In this study, we measured the trace element concentration in plagioclase of the AD 2000 volcanic products to reveal the change in magmatic conditions (e.g., temperature, pressure, melt composition) prior to the eruption, using LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) at the GSJ-Lab (New Wave Research NWR213 + Agilent 7700x) with the method by Yamasaki et al. (2015). We found that the Mg, Ti, Fe contents and Sr content in plagioclase were increased and decreased, respectively, from AD 1663 to 2000 eruption, which were consistent with our SIMS (Secondary Ion Mass Spectrometry) analyses for plagioclase in the former products (e.g., AD 1977, AD 1943-45; Tomiya et al., 1998). We consider that the change was caused by mixing of mafic components. We are also conducting melting experiments of Us-2000pm to


Objective
To study the effect of octreotide combined with lactulose enema therapy in the treatment of acute pancreatitis.

Methods
80 cases with acute pancreatitis were selected as the research subjects, they were randomly divided into two groups, 40 cases in each group.The control group was treated with octreotide, and the observation group was given octreotide combined with lactulose enema treatment.The clinical total effective rate, symptoms time, hospitalization time and inflammatory cytokines were compared in the groups.

Results
The total effective rate of the observation group was significantly higher than that of the control group (95.00% vs.80.00%, χ2=4.114, P<0.05). The remission time of abdominal discomfort, intestinal function recovery time, serum amylase recovery time and hospitalization time in the observation group were (2.19±0.82)d, (2.96±1.15)d, (4.67±1.43)d, (10.37±2.14)d, respectivel, which were significantly shorter than those in the control group (t=8.266, 5.516, 8.084, 8.376, all P<0.05). After treatment, the levels of TNF-alpha, IL-6, hs-CRP in the observation group were (36.78±14.67)ng/L, (109.53±36.29)pg/mL, (10.32±3.89)mg/L, respectivel, which were significantly lower than those in the control group (t=4.424, 4.386, 4.622, all P<0.05).

Conclusion
The curative effect of octreotide and lactulose enema in the treatment of acute pancreatitis is significant, it can effectively improve the patients' clinical symptoms, also can inhibit the inflammatory cytokines and improve the prognosis.

I once invented a character called the Testing Nerd, a bespectacled boffin who seemed to lurk in the bowels of every marketing department I ever served. The Testing Nerd could never be satisfied with simple success or failure. Raw response and simple profitability were mere stepping-stones on the way to greater, if more ethereal, wisdom. 'I know it looks good,' he would say, 'but if we had included the second lift letter, plus a sample of pre-2002 lapseds and increased the cell test in Glamorgan, we'd have achieved an 0.23 per cent uplift overall.' He will gibber when he gets his hands on this new book by Mal Warwick. For its 240-odd pages are devoted to testing in true nerdish detail. Indeed, whole sequences of pages are devoted to response data — a fairly shameless degree of padding, it seems to this curmudgeon. But I am still commending this book, if only because most of its lessons seem to have gone relatively unrecorded in the rush towards to a more intellectual theory of direct marketing in the last decade. This is tradecraft, late-1980s style, and younger managers may find it surprisingly informative. One word of warning and several of commendation. Mal Warwick is a fundraiser and just about every example in his book comes from the world of appeals and good causes. So the language is of 'the ask' and 'donor acquisition' and 'resolicitation'. But, with some knowledge of both camps, I'd insist that the lessons learned in fundraising direct mail are very often applicable to the world of Mammon — charities, after all, sit closer to the till than most direct marketers. But hundreds of tests are reported here in utter detail. And even the chapter headings are worth capturing as a checklist of what can be tested — inserts (enclosures to us), postage, outer envelopes, outer envelope messages, BREs, letter length, gift amounts, credit card options and the like. And there is a wide-eyed honesty about the presentation of all this. The author acknowledges that 'this book presents relatively little material on the subject of list testing — and, as you'll soon learn, the audience is the most important thing to test'. Well, yes, Mal. Wide-eyed is actually not a bad epithet for this volume. It has the almost messianic self-belief of the true American direct marketer and is naturally immune to irony. The report on the environmental organisation whose response fell when it used the 'recycled paper' legend in the mailing causes the author to ruminate out loud about how little we The Testing Nerd

In recent years, more and more liquid fertilizers have been used in vegetable and fruit production. Typically, UF/IFAS recommendations are expressed as pounds per acre or kilograms per hectare. Thus, conversion either from a dry fertilizer basis (the UF/IFAS recommendation) to a liquid fertilizer basis, or from a liquid fertilizer source to the UF/IFAS recommended nutrient rate is often required for correct application rate. This 5-page fact sheet helps growers understand the conversion method from liquid to dry fertilizer. Written by Guodong Liu, David Sui, and Gary K. England, and published by the UF Department of Horticultural Sciences, April 2012.

This study examines how non-linearity and asymmetric demand, as well as the endogenous entry of suppliers, affect an intermediary's choice of being a platform, a merchant, or a hybrid of the two modes, and identifies the conditions for each mode of market making to be chosen. Further, we provide the ranking of social welfare for these three modes. We also identify the conditions under which the intermediary's optimal mode of market making is socially inefficient, thus providing justification for the regulation of intermediaries. Moreover, we provide a ranking of the equilibrium quantities under the three modes considered.


Abstract In a previous paper [1] we have noted that the most general oscillator that can be realized, according to Classical Mechanics, is the Newtonian or elliptic oscillator, which is a particular anharmonic oscillator. We have also seen [1] that with this oscillator it is possible to explore the microscopic world finding a new solution for the energy levels of the hydrogen atom and a new solution of the black body problem in quite good agreement with experimental reality. In this paper we will consider again the latter problem, following in every detail the Rayleigh and Jeans (R&J) reasoning, a procedure which we didn't follow previously [1]. In such a way we will obtain a solution practically coincident with the experimental results, showing at the same time that the Energy Equipartition Principle (E.E.P.) is not valid. Moreover, this solution seems to indicate a new approach to the calculation of the spectral line intensities.


Soft-tempered and fine-grained steel is preferred for film-laminated steel sheets for drawn cans in view of surface deterioration resistance and high formability. Although Nb-added ultra-low carbon steel is used for forming application of cans, the problem of surface deterioration resistance still remains after drawing and ironing. In this study, the further grain refinement of conventional Nb-added ultra-low carbon steel has been attempted. As a result, carbon and niobium contents having an excellent balance of grain size and steel plate strength has been found.


Metaheuristic algorithms have been used in various domains to solve the optimization problem. In metabolic engineering, the problem of identifying near-optimal reactions knockout that can optimize the production rate of desired metabolites are hindered by the complexity of the metabolic networks. Through Flux Balance Analysis, different metaheuristics algorithms have been improved to optimize the desired phenotypes. In this paper, a comparative study of four metaheuristic algorithms have been proposed. Differential Search Algorithm (DSA), Particle Swarm Optimization (PSO), Artificial Bee Colony (ABC) and Genetic Algorithm (GA) are considered. These algorithms are tested on succinic acid production in Escherichia coli. The comparative performances are measured based on production rate, growth rate, and computational time. Hence, from the results, the best metaheuristic algorithms to solve the metabolic network optimization is identified.


Our comprehensive analysis suggests the heating origin of key findings by the authors of the commented letter, hence rendering irrelevant their conclusions.


This paper aims to describe the cataloging process of closing mechanisms of traditional jewelry, so that they can be adapted to additive manufacturing production. Such cataloging took place within the scope of the research project "Creative processes for modeling and manufacturing fashion artifacts using a 3D printer", that resulted in the design of the collaborative, open platform MuVuCa to host jewelry productions available for download, modification and printing. The method employed for this work is characterized as "Research for Design", dealing with the collection and processing of data in order to provide knowledge to subside the design process, composed by the phases of survey, classification, comparison and synthesis. As a result, we have a compendium of mechanisms, available for free consultation.


This paper aims at diagnosing the fault of rolling bearings and establishes the system of dynamics model with the consideration of rolling bearing with nonlinear bearing force, the radial clearance, and other nonlinear factors, using Runge-Kutla such as Hertzian elastic contactforce and internal radial clearance, which are solved by the Runge-Kutta method. Using simulated data of the normal state, a self-adaptive alarm method for bearing condition based on one-class support vector machine is proposed. Test samples were diagnosed with a recognition accuracy over 90%. The present method is further applied to the vibration monitoring of rolling bearings. The alarms under the actual abnormal condition meet the demand of bearings monitoring.


Many traditional technologies exist in the dynamic verification field. These are for instance virtual prototyping, simulation, emulation, FPGA based in-system verification and FPGA based system prototyping. Many attempts have been made in the past to find hybrid solutions which are supposed to be superior to these basic technologies. The goal is to find the right trade-off between cost, bring-up time, compile/synthesis time, design capacity, execution speed and their possibilities to be used in-system. This paper proposes a novel many-core hardware system and a design compilation flow, which combines most advantages of the aforementioned methodologies. Most noteworthy are the low cost, the high signal visibility, the fast execution speed and its extremely high capacity of multi-billion gate designs.

The largest troop consisting of 89 individuals was recorded from Prangal panchayat of Bharmaour block and an isolated single young individual was noticed on Koti Bridge near Sundla. There is seasonal but local migration of grey langur in the study area and species has conflict with human being due to shrinking of habitat and other natural resources.


Bruce Johnson's study of the influence of Australian jazz
on the development of popular music in Europe, provides important 'complications' to assumptions about the global diffusion of contemporary (music) culture.


used them as they are, off the shelf. We believe that such a comparison will be useful for understanding the Arctic system, and may also help reconcile contradicting process studies and model evaluations based on different data sources. Our attempt was not to modify or develop the datasets to the extent that they provide the best possible results, but to present them as they are and highlight the strengths and weaknesses in each case. In particular the use of the 2B-FLXHR has been criticized as only clouds detected by CloudSat are included in the radiation transfer calculations, hence the important low level clouds are missing. We agree with the reviewer that it is indeed a very strong caveat to use the 2B-FLXHR dataset within the Arctic. However, to quantify the limitations of the datasets is one of the results of this paper.

Supplemental Digital Content is available in the text. Mechanical unloading with left ventricular assist device (LVAD) support can lead to clinically meaningful reversal of stress-related compensatory mechanisms. However, true assessment of left ventricular ejection fraction (LVEF) is not possible, whereas the left ventricle is unloaded by LVAD therapy making identification of patients with myocardial recovery even more challenging. We introduce our new protocol, the "reverse ramp test" for HeartWare HVAD, HeartMate II, and HeartMate 3. The reverse ramp is transthoracic echo (TTE) and right heart catheterization (RHC)-based protocol with LVAD turn down steps to minimal support allowing for a more accurate assessment of myocardial function.


A matching $M$ in a graph $G$ is said to be uniquely restricted if there is no other matching in $G$ that matches the same set of vertices as $M$. We describe a polynomial-time algorithm to compute a maximum cardinality uniquely restricted matching in an interval graph, thereby answering a question of Golumbic, Hirst, and Lewenstein [Algorithmica, 31 (2001), pp. 139--154]. Our algorithm actually solves the more general problem of computing a maximum cardinality "weak independent set" in an interval nest digraph, which may be of independent interest. Further, we give linear-time algorithms for computing maximum cardinality uniquely restricted matchings in proper interval graphs and bipartite permutation graphs.


The World Health Organization (WHO) recommends social distance as a way to keep COVID-19 from spreading in public settings. People are being advised to limit their contact with one another in order to reduce the risk of illness transmission through manual or direct interaction. To guarantee social separating convention out in the open spots and workplaces, a social distancing detection tool that analyses real-time video inputs from the camera to see if the humans are keeping a safe distance from each other, by investigating from CCTV, Checking People at factories, gyms, platform, workplaces, shops we can incorporate this tools to their surveillance camera frameworks and can screen whether individuals are staying away from one another or not. The Output is utilized for figuring the distance between each pair of individuals identified. This methodology of social distancing calculation will red mark the individual who is approaching an acceptable limit.


In the present work the remains of mastodonts from the middle Miocene of Tarazona de Aragon (Zaragoza) are studied and their taxonomic classification to Gomphotherium, Zigolophodon or Archaeobelodon is discussed. The teeth studied are of bunodont type. The upper incisors present ventral enamel ribbon on the apex. The lower incisors exhibit piriform-flattened transversal sections. The above mentioned features exclude their classification as Z. turiscensis . The dorsoventrally flat-shaped lowers incisors of Tarazona seem to suggest the presence of Amebelodontidae family but due to other features these pieces have been attributed to G. angustidens . Furthermore, some diagnostic-charasteristics of the genus Archaeobelodon are discussed.


By means of the TEX_ 86 proxy, which is independent from changes in the chemistry and oxygen isotopic composition of ambient seawater, Forster et al. obtained the of Mid-Cretaceous (Albian-Santonian) (sea surface temperatures) (SSTs) record of Demerara Rise, which was located in the western tropical Atlantic Ocean during Mid-Cretaceous. In the Mid-Cretaceous, a gradual getting warm trend, lasted up to the Turonian-Coniacian, of SSTs started since Cenomanian (ca. 31℃—35℃), and the maximal SSTs is over 35℃ near Cenomanian-Turonian boundary. However, two cooling events (ca. 2℃—3℃) disrupted the stable warming trend of Mid-Cretaceous. In Coniacian, the SSTs were stepwise declined, reaching the minimum in Santonian (32℃—33℃). Such results have shown, in the geological history, even during the extremely warm green house, the Mid-Cretaceous, the climate is unstable. The factors driving the climate changes are compositive, but mainly the variation of angle between the earth axis and the equator, the strength of the sun's radiation and the action of materials and structures in deep-earth level. Otherwise, any independent event hardly affects the global climate. Although climate does not directly influence the organic evolution, palaeoclimate plays an important role in studying major geological events including stratigraphic boundary, and fossil is, therefore of the most critical indexes of reconstructing the palaeoclimate.


Education is the backbone of any nature of development in any nation worldwide be it social, economic, cultural, political and technological development just to mention a few. However, Covid–19 pandemic paralyzed the entire system of education and hence brought an extremely great uncertainty in the education sector in the entire world, Kenya included. This research paper therefore gives a better understanding of the nature of the uncertainty caused and brought about by Covid–19 pandemic on the education sector in order to chat the best way(s) possible to navigate through it. The study gives the overall views, challenges and possible suggestions particularly in relation to Kenya. It is anticipated that the outcomes of this research paper will enable the government of Kenya and all stakeholders in the education sector within and without Kenya to identify and implement emergency response policies frameworks to mitigate Covid–19 pandemic and other similar emerging disasters that could impact negatively on the education sector. It is further hoped that this paper will contribute to the existing body of research knowledge by laying a base that will enable future researchers to research further in this area of study.

Well known in the theory of network flows, Braess paradox states that in a congested network, it may happen that adding a new path between destinations can increase the level of congestion. In transportation networks the phenomenon results from the decisions of network participants who selfishly seek to optimize their own performance metrics. In an electric power distribution network, an analogous increase in congestion can arise as a consequence Kirchhoff's laws. Even for the simplest linear network of resistors and voltage sources, the sudden appearance of congestion due to an additional conductive line is a nonlinear phenomenon that results in a discontinuous change in the network state. It is argued that the phenomenon can occur in almost any grid in which they are loops, and with the increasing penetration of small-scale distributed generation, it suggests challenges ahead in the operation of microgrids.

We show that any quartic extension of a local field of odd residue characteristic must contain an intermediate field. A consequence of this is that local fields of odd residue characteristic do not have extensions with Galois group A4 or S4. Counterexamples are given for even residue characteristic.


Localization errors posed by anchor misplacement have generally been overlooked in localization research. Previous studies in this field were focused on measurement errors. In this paper, we study the effects of anchor node misplacement, in terms of distance rather than orientation, on the localization error. We propose a distributed and deterministic detection algorithm to identify misplaced anchor nodes and to discard them. We evaluate the performance of our proposed algorithm, and compare it to the algorithm in. Results show that our proposed algorithm is far more conducive to wireless sensor networks (WSNs), results in higher detection rates of misplaced anchors, and provides more effective mitigation.


ABSTRACT The half-metallic and ferromagnetic properties of Co2TiZ (Z = Al, Ga, In) Heusler alloys are investigated. The structural stability is analyzed among the two possible structures, namely, L21 (Cu2MnAl phase) and XA (Hg2CuTi phase) structures. It is found that these alloys are stable in L21 (Cu2MnAl phase) structure. The electronic structure of Co2TiZ reveals that these alloys exhibit half-metallic ferromagnetism with small spin-flip gap at the minority spin state. As the pressure is increased, ferromagnetic to non-magnetic phase transition is observed at the pressures of 380.9, 363.0 and 317.8 GPa for Co2TiAl, Co2TiGa and Co2TiIn, respectively. Half-metallic to metallic phase transition occurs in Co2TiAl, Co2TiGa and Co2TiIn at the pressures of 76.5 GPa, 73.1 GPa and 63.9 GPa respectively.


Major and incompatible trace element abundances and ratios show variable values, which allow several compositionally distinct magmatic provinces to be distinguished. These are separated by deep faults and are characterised by distinct lithospheric mechanical characteristics, e.g., Moho depth and lid thickness. Radiogenic isotope compositions (Sr, Nd, Pb) of mafi c rocks show continuous variations connecting three distinct mantle reservoirs: HIMU-FOZO, EM2 and a high-87Sr/86Sr low-206Pb/204Pb mantle reservoir. The latter is typical of the Italian region and is called ITEM (Italian Enriched Mantle).

poly-chemotherapy, only one paper reported an occurrence of Steve-Johnson syndrome in a patient treated with rituximab. However, no case of TEN have been reported in humans, but only in two Rhesus Macaques (Macaca Mulatta). The pathogenesis of TEN is still unclear. It was observed that activated T cells secrete a large amount of TNF-a and interferon-c, resulting in a Fas-ligand (FasL) up-regulation and Fasmediated keratinocyte apoptosis. This pathway could explain the pathogenesis of TEN after rituximab administration, since rituximab induces a sensitization to Fas-mediated apoptosis through the activation of caspase-8. At the same time, etanercept blocks this inflammatory pathway via TNF-a inhibition. As reported in a previous paper 7, only a 50 mg sub-cutaneous administration of etanercept was needed to block TEN. TEN can be a serious, sudden, and unexpected side effect in patients treated with rituximab, as well as with other drugs. The current report highlights how etanercept is a useful and manageable drug to treat this dangerous skin condition.


Using time-resolved (TRPL) and continuous-wave photoluminescence (CWPL) we have studied GaAs/partially ordered Ga0.5In0.5P single quantum well samples at pressures up to ≈5 GPa. In such samples emission from the quantum well is only seen if intermediate GaP layers are grown between the GaAs and GaInP and is otherwise masked by anomalous bands at around 1.46 eV. Examination of the TRPL spectra shows large differences in the pressure dependence of this emission because of the inequivalence of the GaAs/GaInP interfaces. For the sample with no thin GaP layer between the upper interface this emission has a very long PL-decay time and a stronger blueshift with excitation intensity at higher pressures. The pressure-dependent PL behavior at lower excitation intensity is close to that of the GaInP barrier. The 1.46 eV emission can be attributed to the spatially indirect transitions at the interface with no GaP layer.


Skin applications of non-thermal atmospheric pressure plasma (NTAPP) have been at-tracting attention from medical and cosmetic aspects. The reactive species generated from plasma sources have been known to play important roles in the skin. For proper applications, it is essential to know how they diffuse into the skin. In this study, the penetration of active species from NTAPP through a skin model was analyzed by UV absorption spectroscopy. The diffusions of hydrogen peroxide, nitrite, and nitrate were quantified through curve fitting. We utilized an agarose gel to mimic epidermis and dermis layers, and we used a lipid film or a pig skin sample to mimic the stratum corneum (SC). The diffusion characteristics of reactive species through this skin model and the limitations of this method were discussed

In this study, the magnetic induction heating of cobalt ferrite nanoparticles with or without silica coating was analyzed for evaluating the feasibility of these materials to be used for magnetic hyperthermia. Particles of approximately 14 and 40 nm were evaluated. For this purpose, we used a magnetic induction system to obtain the specific absorption rate (SAR) values. Two di erent amplitudes of 35 mT and 63 mT at 180 kHz were used. Our results showed the smaller particles exhibiting the higher SAR value, independent of the intensities applied. Moreover, there was no significant change in the SAR values for both particle sizes in presence of silica. However, silica increased the hydrolytic degradation.


Packet classification problem has received much attention and continued to be an important topic in recent years. In packet classification problem, each incoming packet should be classified into flows according to a set of pre-defined rules. Grid-of-tries (GoT) is one of the traditional algorithmic schemes for solving 2-dimensional packet classification problem. The advantage of GoT is that it uses the switch pointers to avoid backtracking operation during the search process. However, the primary data structure of GoT is base on binary tries. The traversal of binary tries decreases the performance of GoT due to the heights of binary tries are usually high. In this paper, we propose a scheme called GST (Grid of Segment Trees). GST modifies the original GoT by replacing the binary tries with segment trees. The heights of segment trees are much shorter than those of binary tries. As a result, the proposed GST can inherit the advantages of GoT and segment trees to achieve better performance. Experiments conducted on three different kinds of rule tables show that our proposed scheme performs better than traditional schemes, such as hierarchical tries and grid-of-tries.

Chemical examination of Citrus sinensis roots var. blood red has afforded seven compounds, which have been identified as methyl tritriacontanoate, pentanoic acid, nobiletin, sinestein, 5, 4'- dihydroxy-7, 3'-dimethoxy flavanone 3-O-β-glucoside and glucose.


ABSTRACT To embrace the digital transformation, the Party press in China started to set up official accounts on social media platforms, hoping to strengthen the CCP's legitimacy while satisfying audiences' expectations. This study focuses on the case of Xiake_Island, an official WeChat account affiliated with the Party newspaper, People's Daily, and tries to explore how new media technology redefines its journalistic practices. Through close observations and in-depth interviews, this study found that propaganda still dominates the production process, but the editors have incorporated some elements of commercialism and professionalism into their practices. They pay more attention to the objectivity and attractiveness of the stories in an attempt to weaken their mouthpiece role. To seek the balance between the political mission and audience demand, the editors of Xiake_Island have developed some strategies. Targeting elite audiences, Xiake_Island produces only high-quality, in-depth stories. When covering negative stories, it criticizes policy implementation by the local government while avoids questioning the legitimacy of the Party's policies. Being firmly subordinate to the CCP, the editors will continue to accomplish their propaganda mission more subtly and softly in cyberspace.


Pulmonary hypertension (PH) associated with respiratory diseases, group 3 in the current classification [1], is one of the most frequent presentations of PH. Chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF) are the two most common respiratory disorders associated with PH. In these conditions the presence of PH is associated with shorter survival [2, 3] and worse clinical course [4]. Yet, much is still unknown about group 3 PH regarding its prevalence in the whole disease spectrum, noninvasive markers that might facilitate its recognition and, most importantly, how to treat it. Pulmonary hypertension associated with respiratory disease is a difficult to manage condition with significant burden http://ow.ly/S1COQ

Relevance: The article deals with modern problems in the field of ensuring the quality of services provided on linear accelerators from the point of view of the regulatory framework, as well as from the point of view of the frequency of control procedures. The scientific novelty lies in elaborating a linear accelerator quality control program with detailed procedure descriptions and testing frequency recommendations.
The study aimed to – develop and test a set of simple methods for controlling the linear accelerator's mechanical and dosimetric parameters, which would meet the minimum requirements for high-tech radiation therapy following IAEA and AAPM international recommendations.
Methods: In developing the quality control program for the TrueBeamSTx linear accelerator (Varian, USA) installed at the Almaty Oncological Center (AOC, Kazakhstan), we relied on the recommendations of the International Atomic Energy Agency (IAEA) and the American Association of Physicists in Medicine (AAPM), taking into account that intensity-modulated radiotherapy (IMRT, VMAT), stereotactic radiosurgery and stereotactic radiotherapy (SRS, SRT), using image-guided radiation therapy (IGRT) will be performed on the accelerator, which imposes more stringent requirements for control of both mechanical and dosimetry characteristics
Results: Over three years of operation, the TrueBeamSTx accelerator shows good stability of mechanical and dosimetric characteristics, verified using systematic tests according to the quality control program developed by the authors of this article. The IAEA/WHO mail dose monitoring program using radiophotoluminescent detectors, implemented in 2019-2022, showed high dosimetric measurements and calculations accuracy of 0.1-1.7%, at a tolerance of 5%.
Conclusion: A quality control program for a high-energy linear accelerator has been developed; the results obtained for all characteristics correspond to the permissible values. The effective and safe use of radiotherapy requires the development of a quality control program for all radiotherapy equipment specifically for each institution and independent verification of the implementation of this program.

Microscopic TV holography is a reliable and versatile non-contact optical technique for whole-field deformation measurements with interferometric sensitivity for many micro-metrology applications. The technique is based on digital speckle interferometric subtraction correlation. Characterization of deformation and surface shape is an important parameter in quality testing of micro objects related to functionality, reliability and integrity of the components. Single wavelength TV holography is used widely for deformation analysis. However the single wavelength TV holographic configuration suffers from overcrowding of fringes for large deformation that sets in limitation due to speckle de-correlation for quantitative fringe analysis. In this paper, we describe a multiple wavelength microscopic TV holographic configuration that uses sequentially recorded phase shifted frames at three different wavelengths before and after deformation of the specimen for evaluation of relatively large deformation fields at effective wavelengths. Use of multiple wavelengths for deformation and shape evaluation is also discussed. The design of the system along with few experimental results on small scale rough specimens

The study was conducted in North Achefer district of Amhara National Regional State in six selected watersheds with the objectives of characterizing the livestock production system and to assess the major feed resources and management. The watersheds were selected purposively based on agro-ecology (mid and low altitude). Moreover, focus group discussions and field observations were done to enrich survey data. The major feed resources biomass estimation in terms of dry matter (DM) was conducted using conversion factors. Diseases such as FMD, internal and external parasite, bloat and Newcastle (poultry diseases) are dominant in the area. Most of the respondents reported that the major water source for livestock during dry season was from well (49.6%) followed by spring water (37.5%) the remaining is from river water (12.9%). The major livestock feed resources available in the study areas were crop residues, natural pasture, hay and improved fodder harvested from backyard and soil and water conservation areas. In the study area, about 32.51% of feed dry matter deficit has been recorded. The major livestock production constraints of the study watersheds were shortage of grazing land, low productivity, disease, shortage of water, shortage of labor and predators in the order of importance. Watershed development is now being an important intervention for natural conservation in the study area and at the same time it is becoming very important to be a livestock feed source if cut and carry system is regularly applied.


Background: Exercise can effectively attenuate withdrawal symptoms and reduce relapse, but it is unknown whether exercise of different intensities produces different results. This study aimed to systematically review the effects of different exercise intensities on withdrawal symptoms among people with substance use disorder (SUD). Methods: Systematic searches for randomized controlled trials (RCTs) on exercise, SUD, and abstinence symptoms were conducted via electronic databases, including PubMed, up to June 2022. Study quality was evaluated using the Cochrane Risk of Bias tool (RoB 2.0) for assessment of risk of bias in randomized trials. The meta-analysis was performed by calculating the standard mean difference (SMD) in outcomes of interventions involving light-, moderate-, and high-intensity exercise for each individual study using Review Manager version 5.3 (RevMan 5.3). Results: In total, 22 RCTs (n = 1,537) were included. Overall, exercise interventions had significant effects on withdrawal symptoms, but the effect size varied with exercise intensity and by outcome measure (i.e., for different negative emotions). Light-, moderate-, and high-intensity exercise reduced cravings after the intervention [SMD = −0.71, 95% CI = (−0.90, −0.52)], and there were no statistical differences between the subgroups (p > 0.05). Light-, moderate-, and high-intensity exercise reduced depression after the intervention [light, SMD = −0.33, 95% CI = (−0.57, −0.09); moderate, SMD = −0.64, 95% CI = (−0.85, −0.42); high, SMD = −0.25, 95% CI = (−0.44, −0.05)], with moderate-intensity exercise producing the best effect (p < 0.05). Only light- and moderate-intensity exercise relieved anxiety after the intervention [light, SMD = −0.48, 95% CI = (−0.71, −0.26); moderate, SMD = −0.58, 95% CI = (−0.85, −0.31)]. Only high-intensity exercise worked in alleviating stress [SMD = −1.13, 95% CI = (−2.22, −0.04)]. Both irritability and restlessness could be improved by light- and moderate-intensity exercise [irritability, SMD = −0.74, 95% CI = (−0.98, −0.50); restless, SMD = −0.72, 95% CI = (−0.98, −0.47)], and there were no statistical differences between the subgroups (p > 0.05). Moderate- and high-intensity exercise decreased withdrawal syndrome after the intervention [moderate, SMD = −0.30, 95% CI = (−0.55, −0.05); high, SMD = −1.33, 95% CI = (−1.90, −0.76)], with high-intensity exercise producing the best effects (p < 0.01). Conclusion: Overall, exercise leads to improvements in withdrawal symptoms in individuals with SUD, but these effects vary significantly between the exercise of different intensities and according to the type of withdrawal symptoms.

The aim of the present study was to describe whether abnormal cervical mucus discharge (A-CMD) or pathogens in cervical mucus discharge (CMD) have effects on reproductive performance of cows and heifers in estrus. Animals having clear discharges (68 cows, 38 heifers) with normal viscosity and without bad odor were grouped as normal cervical mucous discharge (N-CMD) group. The other animals (84 cows, 32 heifers) were grouped as A-CMD group. Microorganisms isolated from samples were divided into three groups as uterine pathogens (UP), potential uterine pathogens (PUP) or opportunistic uterine pathogens (OUP). Presence of PUP was associated with A-CMD for both cows (p<0.01) and heifers (p<0.02). First service conception rates (FS-CR) were lower in cows positive for PUP (p<0.01). Moreover, presence of PUP and OUP affected FS-CR in heifers (p<0.01). Although A-CMD significantly affected FS-CR in cows (p<0.04), it did not affect FS-CR in heifers. Differences in average open day for cows (p<0.02) and first service age for heifers (p<0.01) were significant between N-CMD and A-CMD groups, respectively. The current study suggested that CMD should be evaluated more carefully when there are infertility problems. In addition to the known microorganism that causes sterility and infertility in the UP group, pathogens in the PUP group should be considered for their potential to cause infertility.

A series of tests has been carried out to determine the relative cold-rolling properties of electrolytic iron as compared with open-hearth steel especially adapted for deep-drawing operations. Representative lots of the two types of material were cold-rolled under identical conditions in order to determine any difference in behavior in the rolls. The material was rolled under both mild and very severe rolling practice. No evidence developed indicating any marked difference between the two types of material. The following tests were made on samples representing each step in the rolling hardness, Erichsen, tensile, and bend tests. These tests showed that electrolytic iron does not harden so rapidly and does not increase in tensile strength so rapidly with cold-rolling as open-hearth steel used for deep-drawing operations. The tensile strength of the cold-rolled material was in all cases greater in the direction transverse to rolling than in the direction parallel to rolling. The hardness was found to approach a maximum with increasing total reductions and then to decrease with further cold-rolling. In general, the tests indicate that electrolytic iron would probably be slightly superior to specially selected commercial open-hearth deep-drawing stock.


Construction and architecture are interrelated and the connection between them is architectural design.
Architectural design is a set of intellectual instruments that applies architectural space as a material.
The architectural space is such an artificially created space that implies the scale of human values

Spherical crystallization enables the direct preparation of crystal agglomerates of active pharmaceutical ingredients (APIs) with improved crystal handling properties. The continuous spherical crystallization of albuterol sulfate as a model API was developed using a mixed-suspension, mixed-product removal (MSMPR) crystallizer. The application of a solvent recycling system for reuse of the antisolvent in the single-stage MSMPR crystallizer was also demonstrated. Spherical agglomerates of albuterol sulfate were obtained via antisolvent crystallization using the MSMPR crystallizer with water as the solvent and an ethyl acetate/emulsifier (Pluronic L-121) mixture as the antisolvent. Steady-state continuous spherical crystallization was rapidly achieved after 30 min, and a yield of >95% was obtained. The influence of process parameters such as the solvent/antisolvent ratio, emulsifier concentration, residence time, and reactor scale on the properties of the agglomerates formed during the crystallization proces...


The mineralization of dipicolinic acid (DPA) molecules in bacterial spore cores with Ca2+ ions to form Ca-DPA is critical to the wet-heat resistance of spores. This resistance to "wet-heat" also depends on the physical properties of water and DPA in the hydrated Ca-DPA-rich protoplasm. Using reactive molecular dynamics simulations, we have determined the phase diagram of hydrated Ca-DPA as a function of temperature and water concentration, which shows the existence of a gel phase along with distinct solid-gel and gel-liquid phase transitions. Simulations reveal monotonically decreasing solid-gel-liquid transition temperatures with increasing hydration, which explains the experimental trend of wet-heat resistance of bacterial spores. Our observation of different phases of water also reconciles previous conflicting experimental findings on the state of water in bacterial spores. Further comparison with an unmineralized hydrated DPA system allows us to quantify the importance of Ca mineralization in decreasi...


A Six DOF nonlinear model of a large unmanned aerial system is developed using two competing approaches in modeling aircraft with V-tail configuration. In one approach the V-tail is projected into horizontal and vertical planes and the aircraft airflow angles, angle of attack and sideslip angle, are used for analysis. This approach has been successfully used to model aircraft with low horizontal tail dihedral however the nonlinear aerodynamics generated by the angularity of airflow is not captured. At large dihedral angles these nonlinearities can increase the uncertainty in physics based models. The second method employs lifting line method to calculate the local angle of attack on the V-tail and the pressure gradient effects from one lifting surface on another in close proximity. This method should reduce that uncertainty in the V-tail dynamics. For comparison of the two competing methods, fuzzy logic modeling techniques with nonlinear aerodynamic modeling capabilities are used for parameter identification of a large unmanned aerial system with a V-tail. Both methods fail to accurately capture nonlinear and unsteady aerodynamics such as yawing moments however, simulation results show moderate improvement in the quality of 6 DOF nonlinear models for longitudinal dynamics if the nonlinear projection method is used.


We consider a hyperspectral image restoration problem in which the solution is known to be nonnegative. The image estimate is obtained as the constrained minimizer of a convex criterion incorporating prior information on its spatial and spectral regularity. We previously proposed a fast algorithm for Tikhonov regularization. Here, we adapt this algorithm to edge-preserving image restoration.


After more than five decades, a huge number of models and algorithms have been developed for data clustering. While most attention has been devoted to data types, algorithmic features, and application targets, in the last years there has also been an increasing interest in developing advanced dataclustering tools. In this respect, projective clustering and clustering ensembles represent two of the most important directions: the former is concerned with the discovery of subsets of the input data having different, possibly overlapping subsets of features associated with them, while the latter allows for the induction of a prototype consensus clustering from an available ensemble of clustering solutions. In this paper we discuss the current state-of-the-art research in which the problems of projective clustering and clustering ensembles have been revisited and integrated in a unified framework, called Projective Clustering Ensemble (PCE). We discuss how PCE has originally been formalized as either a two-objective or a single-objective optimization problem, and how the limitations of such early approaches have been overcome by a metacluster-based formulation. We also summarize main empirical results, and provide pointers for future research.


This book is a collection of 22 extended articles by a variety of authors. The chapters are organized into five sections which derive from an approach to creating a 'theoretical structure for virtual integration', which the writers label 'Virtual Enterprise Integration Semiotics'. 'Integration Semiotics' is based on a sociotechnical approach and argues the importance of considering social and human perspectives as well as technical perspectives when creating virtual enterprises. Thus, the chapters consider various functional and organizational issues as well as technologies for integration, and the book concludes with three case studies. The book is clearly written with postgraduate students and academic researchers in mind. The approach adopted in many of the chapters is highly theoretical and abstract, with very limited reference to virtual enterprises in practice. An exception perhaps is the chapter on the collaborative network model by Ellmann and Eschenbaacher, which seeks to draw out, for example, a useful list of functional requirements for collaborative networks. Many of the other papers are very conceptual in their presentation. A later chapter, dealing with the issue of 'automatic negotiation and operation monitoring', written by Rochas, Cardosa and Oliveria, is perhaps more representative of the tone of the book in that it focuses on what are interesting theoretical frameworks for modelling the negotiation process, but offers little in the way of insight or advice to the practitioner. Overall, the standard of the individual essays is high and the editors have clearly worked hard to create a conceptual framework – Semiotic Integration – into which to fit the various contributions. It is definitely a book for the academic researcher, rather than the practitioner.


This paper is a survey of relevant empirical literature pertaining to knowledge heterogeneity. Its purpose focuses on highlighting issues surrounding its definition and measurement. First, it shows that knowledge heterogeneity is definitionally close to several other concepts, each measured in a certain way. Second, the same measures have been used indiscriminately for several of these concepts. Third, different measures have been used for the same concepts. The point being made is that comparable empirical results cannot be achieved if the same measures are used for different concepts. Research in knowledge management and innovation management centered around knowledge heterogeneity could be impeded if different emphases are put on different words while studying a concept that is defined similarly across studies yet measured differently, or that is measured similarly despite being defined differently. Results in future research are more likely to converge if knowledge heterogeneity is defined separately from similar concepts such as knowledge sharing and knowledge overlap, for example.


Marine carbonate layers have been the focus of the domestic oil and gas exploration with difficulty,for there are complex terrain and complex geological layers in the southern karst exploration area.The accuracy of velocity analysis,which is the key stage of seismic data imaging,will be influenced by the characteristics of doubly complex effects,for there are more than one tendency of velocity in target area.In this paper the accuracy of velocity analysis in karst exploration area is analyzed.Namely,the accuracy of velocity analysis is affected not only by the weak signals of carbonate layers,but also by the complex secondary waves.On this basis,the errors in actual velocity analysis of seismic data obtained in that area are discovered,and the different influence of multiple waves and the secondary waves on velocity analysis should be strictly distinguished.We put forward a proposal that the velocity should be analyzed in common scatter point gather(CSP)theoretically and practically,which will has a strong guiding significance for the seismic data s processing and interpretation of the marine carbonate layers.


A casino gaming apparatus is provided that allows the user to lock the casino gaming apparatus for a predetermined amount of time in order to hold the casino gaming apparatus until the user returns from a break. The invention provides for an identification reader Such as a card reader for reading user information, and for setting the casino gaming apparatus in an out of order mode for a predetermined amount of time. The predetermined amount of time can be based on the length of play of the user on the casino gaming apparatus, or on a status of the user. The user can request an amount of time to set the casino gaming apparatus to an out of order mode, and if the user does not return in the predetermined amount of time, the casino gaming apparatus can be set back to a stand by mode.


The directed transverse momentum, , of light particles (p,d,{hor_ellipsis}) is produced through the interplay of the nuclear mean field and nucleon-nucleon collisions. contains a random component and a component due to the collective momentum transfer. For intermediate and heavy mass fragments, the random component is expected to diminish, whereas the collective momentum transfer increases in importance. The authors intend to corroborate this by using the optical model of transverse momentum transfer for the systems Ar, Nb, La and Au at GeV per nucleon energies and present calculations for P{sub {perpendicular}} (Bounce)/A{sub F}, where P{sub {perpendicular}} (Bounce) is the extra component needed to fit the transverse momentum widths of fragments. The role of the nuclear mean field in determining the fragment momentum widths will be discussed.


material and structures. Among the most promising composite structures which is the honeycomb (HC) sandwich structures, especially reinforced with composite material panels. It has been widely used in the components of some mass transport tool due to its attractive properties such as energy absorption, force resistance and massive weight reduction. There are low velocity and high velocity impact that can be cause on a structure. A study by R. Bogenfeld [5] explain that composite structures in aerospace application are likely to be exposed by a velocity impact cause by runaway debris, hail and ground handling accident. The associated impact damage consists mainly of delamination and matrix cracking, which is located inside the laminate and often invisible from the outside thus a barely visible damage occur. It is well-known that the pearls found inside the mussels, iridescence to Abstract: This study presents the numerical simulation of seashells plate subjected to impact using hemispherical and blunt projectiles. The geometry size of the seashells target is 80mm x 8mm x 10mm and the projectiles used were hemispherical and flat shape. Mesh sensitivity analysis have been implemented in this study to determine better result and visualization for the projectile ballistic limit velocity and plate damage characteristics. Ballistic limit velocity and residual velocity for both projectiles were compared. For residual velocity, the hemisphere projectile had lower residual velocity than blunt projectile. For ballistic limit velocity the blunt projectile had higher velocity compare to hemispherical projectile. Damage characteristics of seashell plate were observed. It was found that hemispherical projectile caused highest plastic deformation and kinetic energy dissipation. The endpoint of the seashell plate subjected to impact by hemispherical face caused major fracture compared to only slight deformation for plate impacted by blunt projectile. The numerical simulation of this research was carried out by using FE software/Explicit.


Turbines in power industry use pretwisted blades of varying lengths, which are mounted on the rotating shafts with one end fitted in the fir tree root of the rotor. The fatigue of these blades may cause crack that starts at the stress concentration regions and may propagate for catastrophic failure. This paper addresses the vibration behavior of the pretwisted blades under the influence of crack. The effect of crack on the natural frequencies of pretwisted blade is investigated by conducting parametric studies using finite element analysis software. The results obtained are used to evaluate the influence of crack on turbine blade after validating with experimental results. It has been observed that the crack in a blade had a considerable effect on the natural frequencies that change with varying pretwist angles in all the modes of vibration. In addition, the crack sensitivity for natural frequencies of long and short blades has been compared and the fatigue behavior of these blades has been analysed.


Maryland arguably holds the distinction of being the state whose early history most directly ensured, and whose citizenry was most directly affected by, the First Amendment's protection of religious freedom. Because of its relatively diverse religious population, Maryland stood out as both a champion of tolerance and a hotbed of discrimination for most of its colonial experience. Similarities have been pointed out between the first provincial government in St. Mary's, Maryland, and the American plan under the Constitution, particularly with respect to religious liberty.This article offers a brief overview of the religious history of Maryland, focuses on important state cases that have contributed to the jurisprudence of the Establishment and Free Exercise Clauses in the First Amendment and examines several unresolved issues engendered by recent litigation and legislation.


6 patients employed in the metalworking industry developed a hand dermatitis after exposure to a vegetable‐oil‐based cutting fluid. After thorough investigation, including patch testing with components in the cutting fluid as well as an oil and cutting fluid series, contact allergy was demonstrated to a fatty acid ester EM‐550 in the cutting fluid.


Many variables of interest in agricultural or economical surveys have skewed distributions and can equal zero. Our data are measures of sheet and rill erosion called Revised Universal Soil Loss Equation ‐ 2 (RUSLE2). Small area estimates of mean RUSLE2 erosion are of interest. We use a zero‐inflated lognormal mixed effects model for small area estimation. The model combines a unit‐level lognormal model for the positive RUSLE2 responses with a unit‐level logistic mixed effects model for the binary indicator that the response is nonzero. In the Conservation Effects Assessment Project (CEAP) data, counties with a higher probability of nonzero responses also tend to have a higher mean among the positive RUSLE2 values. We capture this property of the data through an assumption that the pair of random effects for a county are correlated. We develop empirical Bayes (EB) small area predictors and a bootstrap estimator of the mean squared error (MSE). In simulations, the proposed predictor is superior to simpler alternatives. We then apply the method to construct EB predictors of mean RUSLE2 erosion for South Dakota counties. To obtain auxiliary variables for the population of cropland in South Dakota, we integrate a satellite‐derived land cover map with a geographic database of soil properties. We provide an R Shiny application called viscover (available at https://lyux.shinyapps.io/viscover/) to visualize the overlay operations required to construct the covariates. On the basis of bootstrap estimates of the mean square error, we conclude that the EB predictors of mean RUSLE2 erosion are superior to direct estimators.

Abstract Pollen grains of 23 species distributed in 15 genera and represented by 64 specimens were analysed using light and scanning electron microscopy to characterise the neotropical genera of Hippomaneae. Five of these species are palynologically characterised for the first time. Hippomaneae pollen is shed in monads, being small to large, isopolar, oblate-spheroidal to prolate, with an amb ranging from circular, three-lobed to distinctly three-lobed, tricolporate, very long colpi (except for Hura crepitans in which is long), margo psilate (rugulate only in Colliguaja brasiliensis), narrow to wide, and endoapertures circular, lalongate to very lalongate, with costae. Sexine thicker than the nexine. Sexine is psilate-perforate except for Algernonia brasiliensis, C. brasiliensis, Gymnanthes multiramea, G. schottiana, Microstachys corniculata, Pleradenophora membranifolia, and Sebastiania brasiliensis where it is microreticulate. Only in M. corniculata the sexine is separated from the nexine at the mesocolpus, forming a cavea. Although the Hippomaneae are considered stenopalynous in the literature, our results showed variation between species and genera groups, reinforcing the relevance of pollen morphology in the systematics of this tribe.


Composition of petroleum can vary within a reservoir fluid system, and this variation is critically important to be modeled. In this work, different compositional grading models are compared to predict compositional changes in a reservoir with measured data. The goal is seeking the model that best describes these changes in composition of the reservoir fluid.


Motion of an elliptic vortex of uniform vorticity in a uniform straining and vorticity flow is solved exactly. The elliptic shape is preserved and the area of the vortex is conserved but the axis ratio of the ellipse changes in general. Depending on the magnitudes of the vorticity in the vortex and the strain and the vorticity of the shear flow, this vortex exhibits various types of motion such as rotation and nutation around its centre. When the strain is very strong, the vortex is always elongated infinitely in the direction of the strain. A stationary elliptic vortex can exist in a weaker straining flow.


The Paxos algorithm is a distributed consensus algorithm, each round of which can be used to agree on a value proposed by a member of the group. The algorithm is tolerant to non-Byzantine errors (e.g. unreliable network environment and disconnected nodes). Despite the simplicity of the algorithm, implementing Paxos for real world applications in traditional languages can be involving and non-trivial[1]. This project implements the basic Paxos algorithm in Haskell, whose power of expressiveness can be helpful to simplify the implementation.
