The molecular composites of ladder polyphenylsilsesquioxane (Ph-LPSQ) and alkoxy substituted polyisophthalamide (Cn-PA) are in situ prepared for the first time by supramolecular template directed synchronous two-step synthesis, mainly including (A) self-assembled ladder superstructure-based synchronous growth polymerization of the silylated diaminophenylene-bridged ladder polyphenylsiloxane (Ph-DLPS) and (B) isophthalylchloride (IPC)-induced synchronous cleavage of the silylated diaminophenylene-bridge and in situ dehydrochlorination condensation. Moreover, novel composite fibers with sub-μm level diameters are prepared by electro-spinning and their morphologies are investigated by SEM. In order to improve the spinning capability, alkoxy groups in different lengths are introduced into the benzene ring of IPC to produce alkoxy substituted polyisophthalamide (Cn-PA). The fiber-forming ability and the morphology of the resulting electro-spun fibers depend strongly on the solvents used, solution concentration and lengths of the alkoxy groups. Uniform continuous fibers of Cn-PA/Ph-LPSQ are spun from chloroform solution. The longer side chains can result in the formation of a fiber with a smaller diameter. The molecular composition mechanism of Ph-LPSQ and Cn-PA is, in particular, examined using FT-IR spectroscopy, indicating that the hydrogen bond between the amide groups of Cn-PA and Si–O–Si bonds of Ph-LPSQ plays a decisive role in their uniform compounding.


A sample of residents of a retirement community was investigated for symptoms and signs thought to be premonitory of stroke, as the initial step in a study of factors that predict the occurrence of stroke. Persons who had experienced a prior stroke reported a number of symptoms more frequently than did persons who had not had a stroke. The stroke group had a higher prevalence of cervical bruits, higher mean blood pressures , and significantly more abnormal electrocardiograms. There were no differences for cholesterol or hemoglobin. Additional Indexing Words: Stroke Blood pressure Coronary disease Cholesterol Hemoglobin THE DEVELOPMENT of techniques for diagnosis and surgical treatment of ex-tracranial occlusive disease has engendered hope that a significant number of the major strokes may be prevented.' As more experience with angiography and arterial recon-structive surgery is gained, these procedures will be increasingly directed toward the stroke-prone individual in order to prevent or postpone the disease. Therefore, techniques and instruments appropriate to the identification of stroke-prone individuals assume increasing importance. In order to assess the value of certain symptoms, physical findings, and laboratory measurements in predicting the occurrence of stroke, a prospective study of an elderly population was initiated in 1964. This first report describes the prevalence of these symptoms , findings, and measurements among persons who have experienced a stroke as 394 compared have not. Abnormal electrocardiograms with a representative group who Methods A population of elderly persons was desired for this assessment so that a sufficient number of cases could be collected in a reasonably short period of time. The persons studied were residents of a retirement community at Seal Beach, California, where a long-term study of cardio-vascular disease was being conducted by the San Francisco Field and Training Station of the U. S. Public Health Service and the University of California. All residents in this community participate in a prepaid medical care program that provides outpatient medical services at a centrally located clinic. Upon assuming residence in the community, each person is invited to receive a routine physical examination, including an electrocardiogram, chest x-rays, and several laboratory determinations.


This article reviews the long-term impact of the COVID-19 pandemic on NHS staff and how these effects relate to the expectations and ambitions of the NHS workforce plan. Findings highlight the need to recognise that the health and wellbeing of existing staff is critical to the attraction of new staff. Acknowledging what staff were exposed to during the pandemic and how they have responded remains important, as does ensuring that there is a sufficient plan for recovery. The offer of health and wellbeing interventions should continue, even if staff need to leave their role in order to come to terms with the pandemic, as this may give them confidence to return to the NHS in future. Educational roles underpin the NHS workforce plan, so care and attention needs to be given to how these staff members are looked after. Finally, it must be recognised that the technological challenges that NHS leaders want to address require innovation and energy that are not naturally present following a global emergency. Recovery must be made a priority if the ambitions of the workforce plan are to be met.


This study examined whether depression mediated the relationship between perceived health status and suicidal ideation among elderly male prisoners in South Korea. Male inmates aged 50 years or older in the correctional facilities were surveyed in December 2020; 141 male participants were included in the statistical analysis. The hierarchical regression results showed that suicidal ideation increased with poorer perceived health among elderly male inmates. Further, perceived health status negatively affected depression, while depression positively affected suicidal ideation. Depression had a significant partial mediating effect between perceived health and suicidal ideation. First-time offenders were more vulnerable to suicide risk than repeat offenders. These findings highlight the need for treatment programs and cognitive-behavioral models to identify inmates' psychosocial risk factors, and assess their mental health. Additionally, correctional facility staff should be educated in suicide prevention, and systematic crisis intervention programs should be provided for those who attempt suicide. This study contributes consideration of the Korean context to the literature on the association among perceived health status, depression, and suicidal ideation in elderly male inmates.


This study aims to analyze the effect of animal protein cooking classes on mothers' upbringing in serving food for stunted children in the working area of the Cihaurbeuti Health Center. The method used is a quasi-experimental study with a non-equivalent control group with a pretest and posttest. The results showed that eight people aged less than 30 years were in the intervention group (38.1%). Then aged 35-40 years, there were eight people (38.1%), while from education, there were nine people with junior high school education (42.9 %), and 18 people worked as housewives (85.7%). In the control group, six people (30%) were less than 30 years old, then 6 (30%) were over 40 years old, while from education, ten people had junior high school education (50%), and 16 people worked as housewives—stairs (80%). The statistical results of the t-test showed an alpha of less than 0.05. In conclusion, cooking class, for example, an animal protein, affects a mother's upbringing in serving food for stunted children.

Lack of applications has always been a serious concern for designing machines with a new but incompatible ISA. To address this concern, binary translation is one common technique to migrate applications from one legacy ISA to new ones. In the past, dynamic binary translation (DBT) has been more widely adopted for migrating applications since it avoids some challenging problems for binary translation such as code discovery for variable length ISA and code location issues for handling indirect branches. Static binary translation (SBT) is usually regarded as a less general solution and has not been actively researched on. However, SBT has advantages of performing more aggressive optimizations, which could yield more compact code and greater code quality. In general, SBT translated applications are likely to consume less memory, processor cycles and power, and can be started more quickly. All the above advantages are more critical for embedded systems than for general systems. Therefore, we believe that even though SBT is not as general as DBT, it has a unique role to play for migrating applications in embedded systems.
 In this paper, we designed and implemented a new portable SBT tool, called LLBT, which translates source binary into LLVM IR and then retargets the LLVM IR to various ISAs by using the LLVM compiler infrastructure. Using the LLVM compiler infrastructure, LLBT successfully leverages two important functionalities from LLVM: the comprehensive optimizations and the retargetability. For example, most DBTs map guest architecture states into the host registers to minimize accessing guest architecture states with memory operations, but must deal with guest architecture state saving/reloading at trace/block entry/exit points. LLBT can treat the complete application binary as a single function and uses the global register allocation optimization in LLVM to consistently map guest architecture states in host registers so as to avoid the costly state saving and reloading at trace/block exits.
 In this paper, we have shown our ARM-based LLBT can effectively migrate EEMBC benchmark Suite from ARMv5 to Intel IA32, Intel x64, MIPS, and other ARMs such as ARMv7. On the Intel i7 based host systems, the LLBT generated code can run 3 to 64 times faster than emulating with QEMU, which uses the DBT technique.


A 1H, 19F and 2H nuclear magnetic resonance study of eight isotopomers of fluoromethane (CH3F) has been carried out under virtually identical experimental conditions. An analysis of the observed anisotropic couplings on the basis of bond additivity has been performed and the underlying assumption of bond additivity has been found to be adequate.In an accurate description of the solute orientation 'non-rigid' contributions such as vibration–rotation interaction, and harmonic and especially anharmonic vibrational corrections have to be included. The present study indicates the presence of a contribution to the observed anisotropic carbon–fluorine couplings due to an anisotropy in J CF.


Peripheral lymphoid and non‐lymphoid tissues receive direct innervation via the nervous system but the relevance of neural input for the mounting of immune responses remains largely unknown. Ablating local innervation to popliteal lymph nodes (popLNs) by unilateral surgical ligation of the sciatic nerve led to footpad edema and dramatic expansion of popLNs due to an increase in cellularity in the ipsilateral side. In contrast, local surgeries leaving popLNs innervated, such as femoral denervation or sciatic denervation downstream of the popliteal fossa, did not generate nodal expansion. The increase in lymph node cellularity could be attributed to B cell proliferation and was associated with enhanced lymphocyte homing from the blood while leukocyte egress into efferent lymph remained unchanged. Homing was a critical factor in this process since blocking leukocyte entry into the lymph node with antibodies directed against L‐selectin or both α4‐ and αL‐integrins ablated denervation‐induced nodal expansion. Higher levels of TNF‐α, IL‐17 and IL‐4 were detected in denervated lymph nodes, the latter of which was also observed by systemic or local sympathectomy. Thus, loss of neural input to lymph nodes resulted in increased cellularity which was dependent on leukocyte homing. These data provide evidence for an important role of direct neural innervation in the control of immune responses.


Adolescence can be defined as the period between childhood and adulthood during which a person attains complete growth and maturity. The rapid change of the early years is gone, and the individual's features assume their adultlike state, and yet, continuous, often even monumental, transformation and development still occur. Moreover, the growth from child to adult is not equal in all aspects of the individual. Some parts will attain maturity before others. This time of transition is not effortless. The questions posed by the adolescent are most challenging. Indeed, the reality faced by the individual at this stage is probably more complex and ambiguous than at any other time. Medical technology can be thought of as an entity that develops through a series of stages in a manner similar to that of humans. Progression occurs from early experimentation and development, to application and verification, and, finally, to acceptance and use. MR angiography is certainly entering the second stage, the adolescence, of technologic development. Since the advent of MR imaging, flow phenomena and imaging not only of the vasculature of the body but also of the flow within its vessels have been subjects of great interest [1-3]. The last several years have seen a multitude of papers describing various techniques for MR angiography. All have been based on either time-of-flight or phase-contrast flow effects, and a prodigious effort has been made to modify and improve the methods. In addition to the developments in sequence design and data acquisition, considerable thought and effort have been directed toward postprocessing methods and display alternatives. The results of this activity have been translated into several commercially available "packages" for performing MR angiography. The wide availability of these methods on MR systems


Developinga drug product with desirable bioavailability is a challenge for sparinglywater soluble drugs such as Fexofinadine hydrochloride.

Conclusion: The resultsobtained from in vitro dissolutionindicated Fexofenadine hydrochloride in SMEDDS dissolved rapidly and completelyin phosphate buffer pH 6.8 which was used as dissolution medium.


Multiple Infrared Sensing Developments is a project that applies the communication of infrared. The concept is the infrared is transmitted by transmitter and receives by receiver. The main thing in the project is infrared detection by a number of receivers. Therefore there are variations of output generated by the compilation of the
receivers. Three receivers are used to detect the infrared signal that generate by transmitter from a certain location and with a certain distance. The compilation of output
is showed by an application to a mobile robot which is moves due to the compilation of receivers that receive the signal. The signal that receives by receivers must be sent to PIC first where it will be process. Signals that come from PIC will control the wheel spin with the help of h-bridge and motor.


A phase detection method includes providing by a controller a second control signal having two or more neighboring pulses when the time during which a state of a second control signal is retained is a predetermined time or more, receiving by the controller phase detection results of a phase of a first control signal different from the second control signal in response to the second control signal, and determining by the controller a phase detection result based on a first pulse of the two neighboring pulses of the second control signal, of the phase detection results.


Objective:To understand the relationship between apoptosis and autoimmune inner ear disease(AIED) through an experimental autoimmune inner ear disease model,and elucidate the expression of apoptosis-related molecules and mechanisms involved in pathogenesis of AIED in the inner ear.Methods:The AIED model were given a subcutaneous injection with inner ear antigens(IEAg),complete freund adjuvant(CFA) and diluted solution pertussis.Auditory brainstem response(ABR) and the expression change of cmyc and Bcl-2 in cochlea were detected.Results:The ABR thresholds from IEAg-sensitized animals were elevated significantly.Cmyc and Bcl-2 can be detected in neuron cell but Bcl-2 positive cells were not detectable in inner hair cells,stria vascularis and spiral ligament both in normal and AIED mice.Two kinds of molecules were detectable on some of infiltrated inflammatory cells,Bcl-2 positive infiltrated cells were increased in number at the late stage of AIED.Conclusion:Both cell and humoral-mediated immune injury cause the AIED.Apoptosis and necrosis may be involved in destruction of cochlear structure as well as its function,apoptosis may play an important role both in inducing damage to the cochlear and inducing resolution of inflammation in AIED.Bcl-2 also plays a crucial role in suppression of the process of apoptosis in cochlea of AIED mice.

It is essential to build proper wave-induced fluid flow (WIFF) models of various scales for analyzing seismic wavefield characteristics and characterizing fracture (or crack) reservoirs. There is much research related to WIFF fractured models that are mainly only suitable for different scales of fracture (crack) medium separately, like microscopic cracks and mesoscopic fractures. Based on previous research, we propose a unified multiscale (mesoscopic and microscopic) dispersion and attenuation model for the medium with fractures, cracks, pores, and fluid. The formulation uses frequency-dependent fractured (or crack) parameters expressed as the form of multiplication of fracture parameters and relaxation function. The advantage of this method is that it is convenient to build fluid porous medium with different scale fractures (or cracks) and various fracture (or crack) configurations. The numerical simulation results prove the correctness and applicability of the proposed extended WIFF dispersion and attenuation model. Based on our proposed method, the characteristics of the dispersion and attenuation of the multiscale fractured model are analyzed. The results show that the characteristics of velocity dispersion and wave attenuation in the medium with different scales of fractures are similar. The velocity increases with frequency and finally tends to be stable. The main difference among the different scales of models is that the frequency bands of the dispersion and attenuation occurring are different. It is also discovered that for multiscale fractured medium, the characteristic frequency and attenuation peaks do not necessarily correspond to each other, which makes the analysis of the dispersion and attenuation more complicated.

Abstract Sixty-eight patients have been evaluated 2 years after stroke concerning their rehabilitation needs, level of disability, health-related quality of life, and satisfaction in various life situations. Assessments of the rehabilitation needs corresponded in general to the results from the different assessments. The neurological deficits and the dependence in personal ADL were rather low, but the majority of patients were dependent in instrumental activities and not fully satisfied with their lives as a whole. The dominant need for rehabilitation interventions was in social-related activities. The present study throws light on the need for systematic follow-up and interventions in stroke patients in the sub-acute and chronic phases.

Many numerically intensive applications require the fast computation of division, square root and elementary functions. Graphics processing, image processing and generally digital signal processing are examples of such applications. Motivated by this demand on high performance computation many algorithms have been proposed to carry out the computation task in hardware instead of software. The reason behind this migration is to increase the performance of the algorithms since more than an order of magnitude increase in performance can be attained by such migration. The hardware algorithms represent families of algorithms that cover a wide spectrum of speed and cost. This thesis presents a survey about the hardware algorithms for the computation of elementary functions, division and square root. Before we present the different algorithms we discuss argument reduction techniques, an important step in the computation task. We then present the approximation algorithms. We present polynomial based algorithms, table and add algorithms, a powering algorithm, functional recurrence algorithms used for division and square root and two digit recurrence algorithms namely the CORDIC and the Briggs and DeLugish algorithm. Careful error analysis is crucial not only for correct algorithms but it may also lead to better circuits from the point of view of area, delay or power. Error analysis of the different algorithms is presented. We made three contributions in this thesis. The first contribution is an algorithm that computes a truncated version of the minimax polynomial coefficients that gives better results than the direct rounding. The second contribution is about devising an algorithmic error analysis that proved to be more accurate and led to a substantial decrease in the area of the tables used in a powering, division iii and square root algorithms. Finally the third contribution is a proposed high order Newton-Raphson algorithm for the square root reciprocal operation and a square root circuit based on this algorithm. VHDL models for the powering algorithm, functional recurrence algorithms and the CORDIC algorithm are developed to verify these algorithms. Behavioral simulation is also carried out with more than two million test vectors for the powering algorithm and the functional recurrence algorithms. The models passed all the tests.


Fushi (服食), a method for treating diseases and nourishing life to achieve longevity, is highly valued and widely used in traditional Taoism. Regarding whether Quanzhen Taoism, a new form of Taoism founded in the Jin Dynasty (1115–1234), practices Fushi, contradictory opinions have been recorded in Collected records written on Qingyan Mountain (Qingyan conglu 青巖叢錄) from the end of the Yuan Dynasty (1271–1368) and The History of the Taoist School founded by (Qiu) Changchun (Changchun daojiao yuanliu 長春道教源流) from the late Qing Dynasty (1636–1912). Today's scholars generally believe that Quanzhen Taoism emphasizes the cultivation of heart and mind and thus has nothing to do with Fushi. This article, centered around early Quanzhen Taoism representatives Wang Chongyang 王重陽 (1112–1170) and the "Seven True Ones (Qizhen 七真)", combines their writings, quotations, biographies, and other materials and discovers that while Wang Chongyang and others heavily criticized the traditional method of Fushi, they also carried out extensive Fushi activities and accumulated rich practical experience in areas such as taking medicine (fuyao 服藥), breathing exercises (fuqi 服氣), fasting (bigu 辟穀), dieting (yinshi 飲食), and using talismans (fufu 服符). Early Quanzhen Taoism both denied and utilized Fushi leading to a contradiction between words and deeds. The reasons for this contradiction can be attributed to two aspects: the internal alchemy thinking of the early Quanzhen Taoism that prioritized Tao over technique (shu 術), and dual cultivation of inner nature (xing 性) and life (ming 命) and prioritizing the former over the latter.

Proportion is to confer the principle of unity upon multiple organs of a construction. This unity can apply to the most immediate perception, such as that of the facade, up to a deeper perception, provided by the plan and section." —Le Corbusier In my thesis, I am trying to discover the beauty of proportion in architecture. I want to find the harmony and relationship between the elevation and interior spaces. After years of architectural learning, I always start a project from plan drawings. But it all finished by designing a facade which is completely separate from the interior space. The question of "How to design an elevation?" has confused me. I believe the design of the elevation should be an integral part of the process of architectural design. Therefore, in this thesis, I made a series of studies about proportion in order to have a deeper understanding of the relationships between elements in architecture. ACKNOWLEGMENTS To my parents, Thanks to my mom and dad for their countless support and care throughout my entire life. I am so grateful for everything I have.

Organizational life is repleate with claims for emancipation. Existing approachs understand these claims either through theories of macro-emancipation (which focus on larger social structural challenges) or micro-emancipation (which focus on everyday challenges). However, these theories fundamentally misrecognise many emancipatory challenges in organizations. Drawing on the work of Jacques Rancière, we argue that this philosophy is fertile for shifting or unframing traditional approachs of emancipation in organization studies. Emancipation is triggered by the assertion of equality in the face of institutionalized patterns of inequality, it works through a process of articulating dissensus, and it creates a redistribution of what is considered to be sensible. By focusing on these three aspects, we argue a whole range of emancipatory struggles that had previously been disregarded by studies of macro-emancipation and micro-emancipation come back into view. This significantly extends how we conceptualise emancipation in organizations and allows us to address some of the shortcomings of existing theories.


Miguel de Cervantes Saavedra was the son of an itinerant surgeon. He wrote a masterpiece of the world literature, El Ingenioso Hidalgo Don Quijote de la Mancha. It is rivalled only by the Bible for the number of languages into which it has been translated. This masterpiece of the world literature is considered to be the first modern novel. For the physician, a reading of the Quijote is likely to veer in a medical direction. Various medical matters arise in the course of the novel, ranging from medical illness, treatments and battle wounds to the psychological profile of their characters. Cervantes's excellent nosological ability is evident when he describes symptoms and signs of illness, derived from being a witness to his father´s medical practice and reading medical books. Don Quixote representing an idealized and fictional world with clear psychotic features. Although Cervantes wrote it four centuries ago, Don Quixote contains plenty of references to different specialties of medicine, and many of the ideas and concepts reflected in it are still of interest. The aim of this paper is to describe briefly the medical environment that surrounded Cervantes and its impact on the Quixote.


Education contributes to the growth of intellectual and scientific potential of society and an individual in particular. Improvement of the forms and content of the educational process at the higher educational institution, active introduction of innovative methods in teaching makes it possible to solve many problems. One of the main objectives of achieving efficiency in teaching is the presentation of knowledge using the latest technology and training aids in the form of a project process. The so-called project method developed by American educators W. Kilpatrick and E. Collings lies at the heart of project technologies. According to H. Selevko, project training differs from the problematic one in the fact that activity of a student has the nature of projecting, which implies obtaining a specific (practical) result and its public presentation [4]. The project training technology is an organization, development and creation of creative products having practical significance by students under the supervision of a teacher. Professor P.I. Obraztsov argues that projecting has a very definite goal, which is to create by a teacher of a special learning environment that allows organizing the pedagogical interaction with students, which guarantees the achievement of the didactic goals set [3]. In our opinion, the basis of the project method is the development of cognitive skills and the ability to independently design their knowledge, the ability to navigate in the information space, the development of critical and creative thinking. The task of this method is to show students their own interest in acquired knowledge, which can and should be needed in life. Consequently, during the application of this method, it is necessary to select a topical, significant problem, the solution of which requires to apply the acquired knowledge, and as a result, to enrich your own knowledge. A teacher can prompt a source of information or direct students' opinions in the right direction. In teaching Russian as a foreign language, this technology provides solution of a problem for students, designed as a project. According to one of the modern developers of this technology E. Polat, "the project method is the essence of developing, personally oriented studying" [2]. The project method is always focused on the independent activity of students, which can be expressed in the form of individual, pair, group work and which they perform for a certain length of time. The project method always involves solving a problem. The solution of the problem set involves the use of a variety of methods and training aids, on the one hand, ПОД-СЕКЦИЯ 6.

Abstract : A three-dimensional crystal structure analysis of 3,3,4,4-tetrahydrofurantetrol determined that this molecule exists in a twisted configuration (44 ring twist), that the space group is P(4)2 sub 1c with eight molecules per unit cell, and that the molecules lie in layers which are held together and interconnected by hydrogen bonds. The trial model was obtained by a new method called vector verification. The method systematically checks, by applying space group symmetry and other conditions, each point in a three-dimensional grid in electron density space. At each grid point, a series of vectors is computed and compared with the observed Patterson function, and only if the vectors exist in the Patterson map can the grid point be considered as a possibility for an atomic position. The trial model was refined using full matrix least squares to a final model having an agreement index of 0.11. (Author)

HuM195, a humanized anti-CD33 antibody, targets myeloid leukemia cells and has modest activity alone against AML. To increase the antibody's potency and allow single cell killing, but avoid the nonspecific cytotoxicity associated with β-emitting isotopes, the α-emitter bismuth-213 ( 213 Bi) was initially conjugated to HuM195. In phase I and II trials, 213 Bi-HuM195 was capable of inducing remissions in AML after partial cytoreduction with cytarabine. Therapeutic applications of 213 Bi, however, are limited by its 46-minute half-life. The isotope generator, 225 Ac, a radiometal which yields 4 α-emitting isotopes and has a 10-day half life, can be conjugated to a variety of antibodies using the bifunctional chelate DOTA-SCN. 225 Ac-containing immunoconjugates can kill in vitro at radioactivity doses 1000 times lower than 213 Bi analogs and prolong survival of animals in several xenograft models (McDevitt et al. Science 2001). We are conducting a first-in-man phase I dose escalation trial to determine the safety, pharmacology, and biological activity of such an in vivo isotope generator using 225 Ac-HuM195. Seven patients (median age, 61 years; range, 46–77) with relapsed (n=3) or refractory (n=4) AML were treated to date. Three had poor-risk cytogenetics. Patients received a single infusion of 225 Ac-HuM195 at doses of 0.5 (n=3), 1 (n=3), or 2 μCi/kg (n=1). Total administered activities of 225 Ac ranged from 23–170 μCi, and HuM195 doses ranged from 1–1.9 mg. No acute toxicities were seen. One of 2 patients evaluable for neutropenia developed an ANC 225 Ac-HuM195. No other grade 3–4 extramedullary toxicities were observed. No evidence of radiation nephritis has been seen, with follow-up to 10 months. To determine pharmacokinetics over 10 days following treatment, we analyzed plasma by gamma counting at 2 energy windows for 2 of the 225 Ac daughters, francium-221 ( 221 Fr) and 213 Bi. Two phase elimination kinetics were seen with mean plasma half-lives t 1/2 -α and t 1/2 -β of 2.9 and 54 hours, respectively. These results are similar to other HuM195 constructs containing long-lived radioisotopes. Antileukemic effects included elimination of peripheral blood blasts in 3 of 6 evaluable patients and dose-related reductions of >33% of BM blasts in 4 patients at 4 weeks following treatment. One patient had 3% bone marrow blasts after therapy. This is the first study to show that targeted therapy with an in vivo α-particle generator is feasible in humans. 225 Ac-HuM195 appears safe and has antileukemic activity. Accrual to this trial continues.


The ultimate goal of short-term tests should surely be to detect the complete spectrum of heritable effects or genetic events involved in the aetiology of cancer. Thus the types of mutational events that must be detected include point mutations, deletions, translocations, rearrangements, aneuploidy and mitotic recombination/gene conversion. The mouse lymphoma assay (MLA) has been widely used for many years for determining the potential for chemicals to cause the full broad spectrum of mutational damage (Applegate et al., 1990; Mitchell et al., 1997). Substantial research has been conducted to understand the capabilities (and limitations) of the assay, its proper conduct and the appropriate interpretation of test data (Clive et al., 1979, 1990; Hozier et al., 1981, 1982, 1989; Moore-Brown, 1981; Cole et al., 1983, 1990, 1991; Turner et al., 1984; Moore et al., 1985a,b, 1989; Blazak et al., 1986; Doerr et al., 1989; Applegate et al., 1990; Moore and Doerr, 1990; Liechty et al., 1993, 1994, 1996; Zhang et al., 1996; Mitchell et al., 1997; Clark et al., 1998). Historically the various international regulatory agencies have required that chemicals be evaluated for their ability to induce point mutations and chromosomal damage. While in recent years some regulatory agencies have chosen to recommend the MLA to meet both of these requirements for the in vitro mammalian assay (Dearfield et al., 1991; Department of Health and Human Services, 1997), others have required the conduct of an in vitro chromosome aberration assay. Thus, it has been necessary for pharmaceutical companies to conduct both an in vitro chromosome aberration analysis and a gene mutation assay (usually the MLA) in order to register their products in the world market. To facilitate the international registration of pharmaceuticals the International Conference on Harmonisation (ICH) was formed to reach consensus concerning both testing requirements and protocol guidelines. The recent Fourth ICH (ICH4) document entitled Genotoxicity: A Standard Battery for Genotoxicity Testing of Pharmaceuticals acknowledged that


Modern preserve technologies and storage fruit practices include the drying of fruits as the most used methods. There are different technical possibilities for fruit drying, from the simplest one in which fruit is dried directly to the sophisticated automatic where in advance all parameters are defined. The quality of dried fruit depends on the quality of the fresh fruit and on the drying methods. The drying costs include the cost of energy investment cost in building and equipment. Appropriate decision requires the knowledge of the value of the dried fruit as well as the drying cost by each position. However, in Serbia often the decision makers consider only technical characteristics of the drying equipment, without economic analysis which often cause very low benefit of dried fruit. The paper is aimed to provide cost-benefit analysis of the most used technical solution of fruit drying in Serbia using several parameters. The economic analysis includes the most important variables by building, equipment, drying process and finally by marketing of dried fruit.


The Markov Switching Model, introduced by Hamilton (1988, 1989), has been used in various economic and financial applications where changes in regime play potentially an important role. While estimation methods for these models are by now well established, such is not the case for the corresponding testing procedures. The Markov switching models raise a special problem known in the statistics literature as testing hypotheses in models where a nuisance parameter is not identified under the null hypothesis. In these circumstances, the asymptotic distributions of the usual tests (likelihood ratio, Lagrange multiplier, Wald tests) are non-standard. In this paper, we show that, if we treat the transition probabilities as nuisance parameters in a Markov switching model and set the null hypothesis in terms uniquely of the parameters governed by the Markov variable, the distributional theory proposed by Hansen (1991a) is applicable to Markov switching models under certain assumptions. Based on this framework, we derive analytically, in the context of two-state Markov switching models, the asymptotic null distribution of the likelihood ratio test (which is shown to be also valid for the Lagrange multiplier and Wald tests under certain conditions) and the related covariance functions. Monte Carlo simulations show that the asymptotic distributions offer a very good approximation to the corresponding empirical distributions. Les modeles a changements de regime markoviens soulevent un probleme particulier connu dans la litterature statistique sous la rubrique des tests d'hypothese dans les modeles ou un parametre de nuisance n'est pas identifie sous l'hypothese nulle. Dans ces cas, les distributions asymptotiques des tests usuels (ratio de vraisemblance, multiplicateur de Lagrange, Wald) ne sont pas standard. Dans le present article, nous montrons que, si nous traitons les probabilites de transition comme des parametres de nuisance dans un modele a changements de regime markoviens et fixons l'hypothese nulle uniquement en fonction des parametres regis par la variable de Markov, la theorie distributionnelle proposee par Hansen (1991) est applicable aux modeles a changements de regime markoviens sous certaines hypotheses. Dans ce cadre, nous derivons analytiquement la distribution asymptotique du ratio de vraisemblance sous l'hypothese nulle ainsi que les fonctions de covariance correspondantes pour divers modeles a changements de regime markoviens : un modele a 2 moyennes avec erreurs non correlees et homoscedastiques; un modele a 2 moyennes avec des erreurs suivant un processus AR(r) ; et finalement un modele a 2 moyennes et 2 variances avec des erreurs non correlees. Dans les trois cas, des experiences de Monte Carlo montrent que les distributions asymptotiques derivees offrent une tres bonne approximation de la distribution empirique. La derivation de la distribution asymptotique de la statistique du ratio de vraisemblance pour ces trois modeles simples markoviens a 2 etats sera utile pour evaluer la signification statistique des resultats qui sont apparus dans la litterature et plus generalement pour offrir un ensemble de valeurs critiques aux chercheurs futurs dans ce domaine. Les valeurs critiques de la distribution asymptotique du test du ratio de vraisemblance dans les modeles a changements de regime markoviens sont considerablement plus elevees que les valeurs critiques impliquees par la distribution chi-carre standard.


Abstract : In the literature there are basically two approaches to the prediction of climatological occurrence (rainfall) statistics: (a) One can use large numbers of observations of climatological phenomena to compile statistics on the probability of occurrence. (b) One can use computational models and available climatological data (past history) to calculate occurrence statistics. Recent modeling attempts start with very small point rainfall distribution functions which are transformed into specific attenuation data. The point rainfall rates are based upon a large history of data which does not indicate the spatial variation of rain. There are, however, indications that outage time on line-of-sight communication links can be estimated from distributions of point rainfall rates. Due to the random nature of rainfall, and due to the time dependence of such information, a logical approach to forecasting this phenomenon and interpreting the results with respect to systems performance seems to lie within the realm of non-stationary time-series modeling. This report presents an attempt to develop statistical models which can be used to forecast in near-real-time and to characterize the underlying stochastic processes of short-term rainfall density information. It should be mentioned that the analysis and modeling are directed towards the accurate characterization of precipitation density and not the probability of precipitation occurrence. Due to the wavelengths involved in Line-of-Sight Communication links, i.e., 5-30 GHz, the size of raindrops have a definite dispersive and absorptive effect on propagated electromagnetic energy. The importance, therefore, of this work is self-evident.


Use of germanium coated substrates for electrodeposited permalloy thin films used as high speed memories remarkablabl remarkabllllremarkablly improves the magnetic properties and their reproducibility. Effective features of the germanium coated substrates (germanium/ silver/glass) were investigated in comparison with the silver coated substrates (silver/glass and silver/germanium/silver/glass), using a B-H loop tracer, an electron microscope and an X-ray diffractometer. The experimental results suggest that the advantage of germanium coated substrates comes from the amorphous structure of a germanium layer. (Received March 23, 1970)


As manufacturers go into volume production with 90 nm designs and below, the floating gate defect (FGD) diagnosis has become a challenge in the initial yield ramp. Since floating gate can result in state-holding, intermittent and pattern-dependent fault effects, these models are generally more complex. Consequently, logical testing is proven can not guarantee the detection of the defect. In this paper, analogue diagnosis to the defect based on defective current is proposed. The magnitude of abnormal increased of power supply current is mainly subjected to the specific location in the Circuit Under Test (CUT), magnitude of input voltage and its sequence. Current open defect diagnosis methods are either keep repeating the circuit simulation based on try and error technique which is tedious or consider part of the factors only for the defect. Thus, the diagnosis results from current procedures may not be as accurate as possible and fully covered. In the proposed method, the significant difference of defective current and the magnitude of voltage supply in sequence are considered using optimization of genetic algorithms (GAs). Results show that the proposed method can achieve a very high diagnosis accuracy and simulation time.


Abstract Copper-benzotriazole (CuBTA) film growth on rolled bronze was investigated by external reflection, also known as reflection-absorption infrared spectroscopy. Results confirm that the film growth in nearneutral conditions is dependent on time and concentration or solvent. New evidence was obtained for step-wise development of the Cu(I)BTA films. Ellipsometric measurements of the thickness of representative Cu(l)BT A films revealed a range of lOO-450Å for immersions up to one week. Electrochemical impedance of several Cu(I)BTA films formed at different immersion times was measured. Some properties of the Cu(l)BTA films, including heat stability, oxidative stability, and ability to form on uncleaned surfaces or under the coating Incralac, were also investigated. These results, viewed in the context of accelerated indoor and natural outdoor weathering of coated bronze and copper samples, also provide a rationale for the limited efficacy of BTA pretreatments often observed on outdoor bronzes. The protection afforded by thin films of CuBTA as normally applied in conservation pretreatments appears to be insignificant compared to the protection afforded by much thicker, polymeric coatings used in harsh outdoor environments.


AbstractThe communication presents the derivation and application of formulas for estimating the parameters MRT and VRT of the linear or linearised complex time invariant pharmacokinetic system, with or without shunt and time delays, defined on the animal body after any route of drug administration. the derivation is based on the model of the system transfer function and/or the model of the system weighting function. Thus the estimation of the system parameters MRT and VRT according to the formulas presented is not restricted only to using experimental data corresponding to the instantaneous system input. the approach provides feasibility of MRT and VRT estimation and may increase the accuracy of the estimates.


Background: An increasing number of medical colleges offer curricular options typically in the form of problem‐based learning (PBL) and conventional curriculum (CC). Purpose: Because these curricula represent radically different theoretical orientations, factors that affect the student's curriculum decision are important to note. Methods: A questionnaire constructed to indirectly assess properties of decision making was completed by 66 students accepted into the Ist‐year class at a dual‐track college of medicine. Results: Analyses indicated 2 distinct groups of decision‐making types. Both groups employed social means to inform decisions, but they varied in terms of activeness, comprehensiveness, and time spent on the decision. More PBL students than CC students engaged in the preferred decision‐making style and used more sources to inform their decision. Among all respondents, information received from current medical students and beliefs about personal learning styles were deemed most important to the de...


Looking at future life scenarios we discover that personal communication devices are expected to play a central role in the organization of the user's life, enabling him to access any information he needs at any time, and taking what action which is useful in his specific situation. This will be done by taking individual preferences and context information into account. Still, these scenarios most often do not outline the impact on the technology platform behind. In this paper we picked up the example of service portals as a simple, well introduced aspect of service provisioning and describe how the enrichment through context awareness will bring us one step closer to those future life scenarios.


The characteristics and kinetics of iron oxide reduction by carbon in biomass composites were studied. Iron oxide can be reduced by biomass very rapidly, and the degree of metallisation and reduction increases with temperature. Iron oxide reduction by carbon in biomass can be divided into two stages: reduction by volatile carbon followed by reduction by non-volatile carbon. The reduction times of the two stages both decrease with increasing temperature. The first reduction is controlled by gas diffusion, whereas the second stage is dominated by carbon gasification.

Distributed computation and storage have been widely used for processing of big data sets. For many big data problems, with the size of data growing rapidly, the distribution of computing tasks and related data can affect the performance of the computing system greatly. In this paper, a distributed computing framework is presented for high performance computing of All-to-All Comparison Problems. A data distribution strategy is embedded in the framework for reduced storage space and balanced computing load. Experiments are conducted to demonstrate the effectiveness of the developed approach. They have shown that about 88% of the ideal performance capacity can be achieved in multiple machines through using the approach presented in this paper.


Cellulose acetate azo-initiator (CAI) was prepared by treating celluose acetate (CAc) with 4, 4'-azobis (4-cyanovaleric acid) (ACVA) in pyridine under the existence of p-toluenesufonyl chloride (TsCI). The degree of substitution (DS) by azo group leveled off with TsCI concentration over 1mol/L and with ACVA concentration over 0.1mol/L for CAc concentration of 0.38mol/L. The reaction was completed within 30min. Vinyl monomers such as styrene (ST) and methyl methacrylate (MMA) were easily polymerized by CAI to prepare the graft copolymers. The rate of polymerization and grafting of MMA were larger than those of ST. Increase in DS by azo group led to incresse in conversion and grafting of monomers. Grafting efficiency of monomers and apparent initiator efficiency (ATE) were 40_??_50% and 0.7_??_1.9%, respectively.

Public procurement ensures accountability, time, and cost savings in procuring goods, works, and services. All government departments use manual and electronic tendering processes to purchase goods and services. The Roads and Highways Department (RHD) is one of the big public departments designated as the study's target population. Manual and e-procurement tendering systems are used by all RHD procurement entities (PE). However, time and cost reduction are significant challenges in the manual tendering process. Because, it involves a lengthy process for Tender Evaluation Committee (TEC) meeting arrangements. However, no time and cost comparison study of the manual and e-GP tendering processes for TEC meeting arrangement has been done in RHD after e-procurement inception in 2011. This study uses a stratified sampling strategy to compare the time and cost of a manual tendering procedure to an e-tendering approach, targeting RHD PE officers as samples. The independent samples t-test model was used to compare two groups utilizing the mean value of TEC meeting arrangement time and cost of the e-tender system and the manual tender system as a continuous normally distributed variable. This study makes a unique contribution by comparing the time and cost efficiency of two sets of manual and e-tender procurement methods. The e-procurement system, according to the survey results, reduced excessive times and costs at TEC meeting arrangements. The findings will also be used to enhance academic research and to improve e-GP policy requirements.


This research aims to develop a remote sensing method for monitoring rice production in Japan. A photosynthesisbased crop production index CPI for rice is proposed that takes into consideration the solar radiation, the effective air temperature, and normalized vegetation index NDVI as a factor representing vegetation biomass. The CPI index incorporates temperature influences such as the effect of temperature on photosynthesis by grain plant leaves, low-temperature effects of sterility, cool summer damage due to delayed growth, and high-temperature injury. These latter factors are significant at around the heading period of rice. The CPI index for rice was modeled at ten monitoring sites in the Kanto, Tohoku, and Hokkaido districts, which occasionally tend to suffer poor harvests as a result of low temperatures. The photosynthesis-based crop production index CPI proposed here can predict the crop situation index of rice by using NDVI, solar radiation at meteorological observatories and air temperature at AMeDAS sites. The method is based on routine observation data, allowing automated monitoring of rice situation index at arbitrary sites in Japan. However, it is possible to further refine the estimation formula for the rice situation index for early monitoring.


Introduction: The long-term adverse effects of transient thyroid function abnormalities at birth on intellectual development are proven. The effect of exercise increases in the presence of sex hormones. The current study aimed at investigating the possibility that a combination of sex hormones and exercise has synergistic effects on neural plasticity in Transient Congenital Hypothyroidism (TCH) rats. Methods: To induce hypothyroidism in the mothers, Propylthiouracil (PTU) was added to drinking water (100 mg/L) on the 6th day of gestation and continued until the 21st Postnatal Day. From Postnatal Day (PND) 28 to 47, the female and male pups received 17β-estradiol and testosterone, respectively. The mild treadmill exercise began 30 minutes after the sex hormones or vehicle administration. On PND 48, electrophysiological experiments were performed on brain slices. Results: Increase of Long-Term Potentiation (LTP) was observed in sedentary-non-hormone female rats of TCH group, compared with that of the control. The exercise enhanced LTP in control rats, but the hormones showed no significant effect. The effect of exercise and sex hormone was not significant in the TCH group. The combination of exercise and testosterone enhanced LTP in TCH male rats, while the combination of exercise and estradiol or each of them individually did not produce such an effect on LTP in TCH female rats. Conclusion: The study findings showed an increase in excitatory transmission despite the returning of thyroid hormone levels to normal range in TCH female rats. Also a combination treatment including exercise and testosterone enhanced LTP in male rats of TCH group, which was a gender-specific event.

Liver fiber is an intermediate and reversible link in the process of cirrhosis, early detection and intervention of liver fibrosis is of great significance for the development and prognosis. Ultrasound as a one of the common diagnostic methods for liver fibers has many advantages like convenience, great accuracy and robustness. However, it is difficult to get subjective and uniform diagnoses because of the ultrasound images can be inevitably affected by the device characteristics, the interactions between ultrasound and body tissues, operation approaches and other uncontrollable factors. So we proposed a new liver fibrosis detecting algorithm based on the ultrasound echo amplitude analysis and a deep learning to classify normal and fibrosis tissue in computer simulation data. In order to study the relationship between scatterer density and hepatic fibrosis, we simulated various scatterer density liver fibrosis ultrasound image by creating random scatterer field and convolving with point spread function. Compared with the detection of traditional statistical analysis and parameter imaging, we use the data of echo amplitude distribution and image gray histogram distribution to classify the category of the window by CNN. The result shows that CNN can provide a better performance in classification and prediction than parameter imaging.


Research in language learning is an area not only affecting researchers but also the teachers who make use of research findings or conduct research themselves. This paper focuses on the issue of reliability and validity of data collection instruments and the effect they have on the final results ofa study. It briefly outlines three research designs which aim at answering the same research questions via different structure elicitation instruments targeted towards the same structure, relative clauses. The instruments include; a translation task, a sentence combining task, and a grammaticality judgement test. It demonstrates the drawbacks and misleading factors involved in using onlyone instrument, even though these instruments have proven valid and reliable in the literature in other studies. Finally, it suggests data triangulation for more reliable results.


Abstract The Impact Ionization Nanowire Multiple-gate Field-Effect Transistor (I-FinFET or I-FET) is investigated. The multiple-gate structure enhances the impact ionization rate in the fin/nanowire, reduces the breakdown voltage VBD and improves device performance. A SiGe Impact Ionization Region (I-Region) is integrated on a Si or Si0.75Ge0.25 nanowire to enhance performance and VBD. Complementary pair of I-FinFETs were realized. Excellent subthreshold swing of sub-5 mV/decade at room temperature was achieved. The lower electron and hole impact-ionization threshold energy of SiGe greatly enhances the drive current of nand p-channel devices. A low VBD of -4.75 V is achieved for SiGe nanowire device. Challenges faced by I-MOS will be discussed.

Digital fringe projection profilometry based on phase-shifting technology is a reliable method for complex shape measurement, and the phase is one of the most important factors affecting measurement accuracy. The calculation of the absolute phase depends on the calculation of the wrapped phase and encoding technology. In this paper, a technique of obtaining the absolute phase of multi-frequency heterodyne fringe images using the Hilbert transform is presented. Since the wrapped phase can be calculated from only one fringe image of each frequency, the method does not need phase-shifting. The absolute phase can be obtained from the wrapped phase by applying the heterodyne method. The measurement time and computational complexity are dramatically reduced, the measurement efficiency is greatly improved, and this benefit from the number of images is greatly reduced. The experimental results show that the method presented in this paper performs well in the application, and the accuracy is no different from that of the phase-shifting method while the efficiency is greatly improved.


The genus Rhodococcus (formerly Gordona (4)) is a recently established genus (1, 3,5,9). Its taxonomic position is between the genera Mycobacterium and Nocardia (4, 9). Several characteristics useful for discriminating between these three genera were described previously (1,4,9). Recently the present writer reported that two anticancer agents, 5-ftuorouracil and mitomycin C, were useful for differentiating rhodococci and rapidly growing mycobacteria from nocardiae. The present paper reports that chromomycin A3 also is useful for differentiating between these genera, i.e., for differentiating rapidly growing mycobacteria from rhodococci and nocardiae. The test strains used in the present study were maintained in our laboratory. They were cultivated on Ogawa egg medium at 37 C for 7 days and used as the source of inoculation. The medium used was a modified Sauton agar medium. Its composition is as follows: sodium glutamate, 4.0 g; KH2P04, 0.5 g; MgS04·7H20, 0.5 g; citric acid, 2.0 g; ferric ammonium citrate, 0.05 g; glycerol, 30 ml; purified agar (Eiken Co., Tokyo), 20.0 g; distilled water, 970 ml. The pH of the medium was adjusted to 7.0 by adding a 10% KOH solution, and the medium was sterilized by autoclaving at 120 C for 20 min. Chromomycin A3 was supplied as a pure powder (Toyomycin for injection) by the Takeda Chemical Industries, Co., Osaka. It was first dissolved in propylene glycol at a concentration of 1 mgjml. This solution and its dilutions were added to the melted medium. Final concentrations of the agent in the medium were 10, 5, 2.5, and 1.25 ftgjml. Control medium contained 1% propylene glycol. The media were then poured in 7-ml quantities into tubes, 165 by 16.5 mm, sterilized by heating at 100 C for 15 min, and made into slopes by cooling. For inoculation, a loop with an inside diameter of 1 mm was used. The loop was touched slightly on the surface of growing organisms used as the source of inoculation, and streaked onto the surface of the test media. The tubes were then stoppered with a rubber cap with a 3 mm line cut in the center of the bottom and incubated at 37 C for 7 days. The concentration of the agent on which the same amount of growth occurred as did on the control medium was regarded as the growth concentration. According to our experience, this method of inoculation


We present a number of breakthroughs for coordinated motion planning, in which the objective is to reconfigure a swarm of labeled convex objects by a combination of parallel, continuous, collision-free translations into a given target arrangement. Problems of this type can be traced back to the classic work of Schwartz and Sharir (1983), who gave a method for deciding the existence of a coordinated motion for a set of disks between obstacles; their approach is polynomial in the complexity of the obstacles, but exponential in the number of disks. Other previous work has largely focused on {\em sequential} schedules, in which one robot moves at a time.
We provide constant-factor approximation algorithms for minimizing the execution time of a coordinated, {\em parallel} motion plan for a swarm of robots in the absence of obstacles, provided some amount of separability.
Our algorithm achieves {\em constant stretch factor}: If all robots are at most $d$ units from their respective starting positions, the total duration of the overall schedule is $O(d)$. Extensions include unlabeled robots and different classes of robots. We also prove that finding a plan with minimal execution time is NP-hard, even for a grid arrangement without any stationary obstacles. On the other hand, we show that for densely packed disks that cannot be well separated, a stretch factor $\Omega(N^{1/4})$ may be required. On the positive side, we establish a stretch factor of $O(N^{1/2})$ even in this case.

Direct lysosomal uptake of α 2 -microglobulin contributes to chemically induced nephropathy. Background An abnormal accumulation of α 2 -microglobulin (α2μ) in kidney lysosomes of male rats has been described in the nephropathy resulting from exposure to a variety of chemicals. The increment in lysosomal levels of α2μ cannot be explained by a decrease in its proteolytic susceptibility. Because a portion of α2μ resides in the cytosol of kidney cells, we decided to analyze whether this cytosolic form also contributes to the abnormal lysosomal accumulation of α2μ after exposure to chemicals. Methods Intact kidney lysosomes were isolated from untreated or 2,2,4-trimethylpentane (TMP) treated rats, and their ability to take up α2μ was compared. Results α2μ can be directly transported into isolated lysosomes in the presence of the heat shock cognate protein of 73kDa (hsc73). α2μ specifically binds to a lysosomal membrane glycoprotein of 96kDa, previously identified as the receptor for the hsc73-mediated lysosomal pathway of protein degradation. In rats exposed to TMP, the specific lysosomal transport of α2μ increases, as well as the ability of lysosomes to directly transport other substrates for this pathway. The increased lysosomal transport is mainly due to an increase in the levels of the receptor protein in the lysosomal membrane. Conclusions The hsc73-mediated lysosomal pathway contributes to the normal degradation of α2μ in rat kidney and liver, and the activity of this pathway is increased after exposure to TMP. Our results suggest that the chemically induced accumulation of cytosolic α2μ in lysosomes is mediated by an increased rate of direct uptake into lysosomes.


The spatial distribution, seasonal abundance, life history pattern, and production of the mysid Mesopodopsis slabberi are described from a warm-temperate estuary on the western coast of Portugal. Mysids were sampled from June 1996 to July 1997, using zooplankton and suprabenthic nets. The higher densities and biomass of M. slabberi were found in upstream areas from the south arm of the estuary. These areas consist of shallow waters with low circulation rates and high residence times, richer in phytoplankton than the rest of the estuary. Mesopodopsis slabberi was abundant in October, November, and December and again in May, June, and July. No mysids were found in January and February, when salinity decreased to values below 5%0 and water temperature was below 10?C, and also in August, when oxygen levels declined and the water temperature reached values above 24?C. Morphometric relationships in M. slabberi were determined from freshly caught specimens. Significant positive correlations between total length (TL) and cephalic length (CL) (TL = 2.5 CL + 0.012) and between dry weight (DW) and total length (LnDW = 3.0298 LnTL - 6.0229) were found. All size classes, from 0.95-11.36 mm, were equally represented throughout the year. Moreover, juveniles, immature females, mature ovigerous females carrying eggs or embryos, and mature resting females were found throughout the sampling period. As a whole, this pattern suggests that reproduction is continuous rather than seasonal. This, together with migrations, made identification and tracking of population groups impossible from the analysis of sizefrequency diagrams. The secondary annual production of M. slabberi was therefore estimated by the Hynes average cohort method. The annual production was 16.02 mg.m-3year-', and the P/B ratio was 2.57.

Multi-Source Feedback assessment (MSF or 360-degree feedback) aims to create change through a comparison of self versus others' ratings. We propose that the ability of an MSF respondent to predict how he or she will be rated by others is more likely to foster a mode of openness over defensiveness.


Micro-reactors are advanced reactors that are designed to be small, scalable, and portable with up to 20 MW power. These reactors could operate independently, or as part of a microgrid, without need of frequent refueling. Micro-reactors are designed to be deployable to provide electric power in remote locations, therefore providing greater flexibility in energy distribution and access.
 Several micro-reactors are under development in the US. These reactors are based on advanced gas-cooled or heat-pipe concepts. While graphite can be found in various applications, some high-temperature reactors plan to employ graphite in their core components due to its role as a moderator and its ability to maintain its structural integrity when subjected to elevated temperatures and high neutron fluence. Although there is significant experience with use of graphite in nuclear applications, there are still unknowns that should be addressed. Graphite properties depend on the graphite type and are affected by the fabrication procedures. Material properties are functions of the temperature and radiation dose and are often affected by the oxidation environment. Therefore, in-depth understanding of graphite properties, including the effect of irradiation, oxidation, and other influencing parameters are required to evaluate the design accurately.
 This paper aims to provide a review of material properties for graphite relevant to micro-reactor design. For this work, two distinct grades of graphite were considered, namely IG-110 and Mersen-2114. Physical, thermal, and mechanical properties for these grades were comparatively evaluated. The properties that are discussed in this draft aim to serve as a basis for design and safety analysis.


Energy harvesting - the conversion of ambient energy into electrical energy - is a frequently used term nowadays. Several conversion principles are available, e.g., photovoltaics, wind power and wa ...


In order to efficiently design power conditioning systems, operating conditions have to be considered. For instance, power converter design should take into account the intermittency of the renewable energy sources and the relatively low efficiency of some of their subsystems such as photovoltaic modules. This paper deals with dc–dc power converter design and aims to improve both reliability and efficiency. The approach adopted is based on a boost-based topology equipped with three MOSFETs in parallel. It uses a novel biobjective algorithm based on a biobjective function that optimizes the power converter efficiency and reliability. The proposed algorithm defines the number of MOSFETs to commutate in order to guarantee the best compromise between the converter efficiency and its reliability, depending on the available input power. The converter efficiency is determined by the power converter losses, calculated using the power device parameters and their junction temperature measurement as inputs. The converter reliability is calculated using its mean time between failures as assessed in the military handbook for reliability prediction of electronic equipment (MIL-HDBK-217F). Experimental results carried out on a 2.5 kW prototype demonstrate the effectiveness of the proposed system and the details from one day's photovoltaic power production are presented and discussed.


Objective To explore the influence of education on early-pregnancy body mass control and guidance on diet on the incidence of gestational diabetes mellitus (GDM). Methods 16 595 pregnant women who had pregnancy tests in our center between Dec. 2004 and Dec. 2007 were divided into the observation group and the control group, according to whether or not they had been offered education on early-pregnancy body mass control and guidance on diet. A comparison was made of the increase in the body mass, the positivity of glucose screening tests, gestational impaired glucose tolerance (GIGT) and GDM between the two groups. Results The body mass increase of the control group was distinctly greater than that of the observation group (P0.01), and the incidence rates of glucose screening test positivity, GIGT and GDM of the former were also significantly higher than those of the latter (P0.01). And compared with the women with normal pregnancy, those with glucose screening test positivity, GIGT and GDM registered a distinctly higher increase in the body mass during pregnancy (P0.01). Conclusion Reasonable control of body mass during pregnancy has a marked effect on the prevention of glucose screening test positivity, GIGT and GDM. Therefore, it is necessary to include the education on body mass control as a routine item in the initial pregnancy test.


Owing to wireless broadcast nature of communication, wireless sensor networks (WSNs) are vulnerable to denial-of-service (DOS) attacks and hole attacks. Preserving security and confidentiality in WSN are crucial, so it is required to design an energy efficient intruder detection system (IDS) to detect and mitigate the attacks. In this paper, an energy efficient intruder detection system based on energy prediction (EE-IDSEP) has been proposed for IEEE 802.15.4-based WSN to detect and mitigate the distributed denial-of-service (DDoS) attack (i.e., resource depletion attack, power exhaustion attack and flooding) and wormhole attacks. The design of EE-IDSEP consists of optimised watchdog system and hidden Markov model (HMM). The wormhole attack is detected using the optimised watchdog system. The optimised watchdog mechanism is a trust-based method which is used to evaluate the validity of all the nodes of the network. The DDoS attack is detected based on energy consumed using the hidden Markov model. The model of EE-IDS is simulated using NS2 simulator and then it is compared with existing energy efficient trust system (EE-TS) in terms of packet delivery ratio (PDR), packet drop, and energy consumption.


We describe a superfluorescent Er/Yb single-mode fibre source capable of generating 1 Watt of output power with variable bandwidths between 0.5 nm and 4 nm


The X(5) symmetry describes nuclei at the critical point of the shape phase transition from axially deformed rotor nuclei to spherical vibrators. 150Nd, 152Sm, and 154Gd were the first nuclei where the predicted charateristics of the X(5) symmetry were observed. Later it was shown that also 176,178,180Os can be successfully described with the X(5) symmetry.In the close vicinity of shape phase transitions one expects strongly changing nuclear shapes. In the X(5) region around A = 150 this was observed for nuclei with different neutron numbers, whereas in the X(5) region around A = 180 this is to be expected for different proton numbers. The aim of the work presented here is the confirmation of a rapid shape change for nuclei close to 178Os. Besides the knowledge on the level scheme of the nuclei of interest, especially absolute E2 transition strengths are crucial for the interpretation of nuclear structure. Prolate deformation is expected for 176W. Thus we performed a recoil distance Doppler shift (RDDS) m...


A stable reference source with a high current capability is useful for many metrological applications. Unlike the conventional Josephson voltage standard, one can couple the programmable Josephson voltage standard (PJVS) to a current source below milliamp range to stabilize the current. For higher current ranges, we tested a feedback method which allowed us to stabilize the 0.1-A output current of a commercial current source to within a standard deviation of 2 /spl times/ 10/sup -8/ A/A.


The syntheses and characterization of linear silarylene-siloxane-diacety-lene polymers 3a-c and their thermal conversion to crosslinked elastomeric materials 4a-c are discussed. Inclusion of the diacetylene unit required synthesis of an appropriate monomeric species. 1,4-Bis(dimethylaminodimethylsilyl)butadiyne [(CH 3 ) 2 N-Si(CH 3 ) 2 -C≡C-C≡C-(CH 3 ) 2 Si-N(CH 3 ) 2 ] 2 was prepared from 1,4-dilithio-1,3-butadiyne and 2 equiv of dimethylaminodimethylchlorosilane. The linear polymers were prepared via polycondensation of 2 with a series of disilanol prepolymers. The low molecular weight silarylene-siloxane prepolymers la-c (terminated by hydroxyl groups) were synthesized via solution condensation of an excess amount of 1,4-bis(hydroxydimethylsilyl)benzene with bis(dimethylamino)dimethylsilane. The linear polymers were characterized by 1 H and 13 C NMR, Fourier transform infrared spectroscopy, gel permeation chromatography, thermogravimetric analysis (TGA), and DSC. The elastomers exhibited long-term oxidative stability up to 330 °C in air as determined by TGA.


The cathode material pyrite (FeS2) (core) was coated with 2.5, 5.0, 7.5, and 10.0 wt% CoS2 (shell) (denoted as FeS2@CoS2) by the hydrothermal method and a subsequent heat-treatment to form composites with enhanced thermal stability and electrochemical performance. Importantly, results indicate indicated that CoS2 particles with a complete crystal structure had been successfully coated on the FeS2 surface. The sample coated with the optimal amount of CoS2, which was determined to be 7.5 wt%, showed the highest thermal decomposition temperature (610.6°C) and excellent specific capacity (as high as 320 mA h g−1 at 520°C and 200 mA cm−2 at a cutoff voltage of 1.6 V), in compared to that of pure FeS2 (551.3°C, 240 mA h g−1). Because CoS2 is an excellent electrical conductor, the surface of FeS2 is modified by CoS2, which leads to the change of the microstructure of FeS2 surface, which enhances the intercalation of ionic electrolyte and enhances the electrical conductivity of FeS2. In the meantime, CoS2 has high thermal stability and exhibits low solubility in the molten electrolyte, which reduces the elemental sulfur loss of FeS2 during discharge and thereby increases the electrochemical capacity.


Objective
To determine the anatomic distribution of metastatic inguinal nodes in gynecological malignancies, and to explore the delineation of clinical target volume (CTV).

Methods
A retrospective study was performed among 34 patients with gynecological malignancies and inguinal lymph node metastases. According to the anatomic distribution of metastatic inguinal nodes, CTV covering more than 95% of inguinal lymph nodes and the relationship of inguinal nodes with the femoral vein, greater saphenous vein and its branches, superficial fascia, and deep fascia were analyzed using vascular enhancement images obtained by computed tomography and magnetic resonance imaging as well as 3D reconstruction using the Eclipse Planning System.

Results
The 34 patients had a total of 145 positive inguinal nodes. In the 131 superficial nodes below the inguinal ligament, 129 were located between the superficial fascia and the deep fascia; the upper group of superficial nodes, containing 25 nodes, was located at 1 cm above the public symphysis and along superficial iliac circumflex vein; the middle group, containing 85 superficial nodes and 11 patients with single superficial node metastasis, was located at the same level of the public symphysis and close to the junction of the saphenous vein and the femoral vein; the lower group, containing 21 superficial nodes, was beneath the public symphysis and along the greater saphenous vein and medial and lateral superficial femoral veins. The 14 deep nodes were located on the medial side of the femoral vein. There were no positive nodes on the posterolateral side of the link between the posterolateral edge of the femoral vein and medial edge of the sartorius muscle. The upper edge of CTV kept 142 lymph nodes beneath the upper edge of the superior pubis ramus and left 3 lymph nodes up to the upper edge of the femoral head. The lower edge of CTV kept 143 lymph nodes above the lower edge of the lesser trochanter and left 2 lymph nodes at 2 cm beneath the lower edge of the lesser trochanter.

Conclusions
For CTV covering 98% of positive inguinal nodes, the anterior edge is the superficial fascia; the medial edge is composed by the inguinal ligament and the border of medial muscle to the femoral vessels; the posterolateral edge is the link between the posterolateral edge of the femoral vein and the medial edge of the sartorius muscle; the upper edge is the upper border of the femoral head; the lower edge is the lower border of the lesser trochanter.

Multimedia Broadcast Multicast Service (MBMS) will be expected to be added into 5G system in the coming 5G release of 3GPP. TV White Space (TVWS) are expected to be effectively used in MBMS mode to solve the problem of spectrum shortage. TV White Space (TVWS) can be organized to provide great help by auction to 5G service providers (SPs) in various scenarios, e.g. mobile wireless communication, Internet of Things (IOT) and Vehicular Network. We investigate imperfect information dynamic Stackelberg Game to allocate the idle TVWS spectrum resources using auction scheme, and, accordingly, the service transaction platform is constructed. First, Hidden Markov Model (HMM) is used to predict the service volume required by Service Providers (SPs). Then, the Nash Equilibrium is achieved by Service Providers, who make strategies based on the forecasting results. Next, Broadcast Operator (BO) allocates the idle spectrum by auction. The simulation results show that the predicted prices are close to the actual transaction prices and the profits of broadcasting operators and services providers are increased simultaneously. This provides solution for the unified regulation of TVWS, incenting the usage of TVWS and providing the feasible scheme that broadcasting can provide the services in 5G.


This paper studies single-user compression for the uplink multi-cell processing (MCP) model where multiple base-stations are connected to a central processor via noiseless backhaul links with a sum capacity constraint. The proposed scheme is based on the virtual multiple-access channel (V-MAC) architecture, where the base-stations quantize the received signals and send the quantized bits to the central processor, and at the decoder side the central processor first recovers the quantized signals then decodes the user messages in a successive manner. This paper focuses on the use of single-user compression in the V-MAC architecture, which is significantly simpler to implement than Wyner-Ziv compression. The main result of this paper is that single-user compression can achieve the sum capacity of the MCP model to within a constant gap under two specific scenarios. First, we define a diagonally dominant channel criterion and show the constant-gap result for the case when the covariance matrix of the received signals across the base-stations is κ-strictly diagonally dominant for some constant κ > 1. Second, we show that the constant-gap result holds for a special class of Wyner channel models in the weak interference regime.


In recent years, reporting scientific experiments became a challenge for scientists working data-intensive research fields. One of these challenges is to accurately report experimental work relying on computational activities. In this report, an exploratory computational experiment is conducted. We evaluate the performance of a set of classification models to extract experimental paragraphs from full-text scientific publications in an unsupervised fashion. The results show that the best performing classification model (Multinomial Naive Bayes) trained on 30 publications in the Proteomics domain achieves a Recall of 87.12% and an Accuracy of 80.63%. Successful unsupervised extraction of experimental paragraphs from reports can considerably reduce the noise present in full-text publications. This approach could be beneficial to automatically generate domain specific vocabulary describing experimental designs and experimental processes. As such, this work contributes to the identification of NLP techniques automatizing the extraction of domain-specific paragraphs which relate to experimental work.


The essence of the Chinese Communist Party's governing of the State and the democratic parties' participation is the Communist Party and the democratic parties fully playing their respective roles, working together on accelerating the progress of "people becoming masters of the country", and safeguarding and developing the basic interests of the largest number of masses during the construction of political power and other governmental works. Cooperation based on performing their respective roles is the distinctive difference between the governing - participating relationships of China and of Western countries. We need to understand precisely the identity, discrepancy and connection between the two.


Abstract : The full funding policy and the three year obligation availability of procurement funds were identified as the major constraints limiting program managers of space weapon systems in their acquisition activities. In order to evaluate the effect of these constraints on space weapon system acquisitions, twelve variables, identified through the literature review, were used to gain an understanding of the problem. Program managers believed that these variables created problems that could only be solved by changing the acquisition process. Personal interviews were conducted and the importance of each variable in affecting the program manager's efficiency was identified. Two data analysis techniques were used: qualitative and factor analysis. Factor analysis was conducted using the rating of importance for each variable and this lead to four underlying factors. The factor identified as limiting program managers the most was labeled program uncertainties.
