Two lithic techno-complexes characterize the terminal Pleistocene archeological record of Beringia. a non-micrublade complex and a microblade complex. Archeologists working in the region have given two interpretations to explain this lithic variability. Some have argued thilt the complexes represent two distinct cultural groups, while others have suggested the variability represents two technological features of a single complex used by a single group of people. These inter pretations are deeply rooted in descriptive analysis and culture history. In this chapter we employ a behavioral approach to explore these explanations by focusing on differences in toolstone procurement and selection represented in two sets of non-mieroblade and microbladc assemblages from the Dry Creek site. Alaska (liSA) and the Ushki-5 site. Kamchatka (Russia). Our results show that toolstone procurement and selection were both unpatterned and unplanned in non microblnde assemblages. but patterned and planned in microblade assemblages.

ABSTRACT As the complementary metal oxide semiconductor feature size shrinks further, single event multiple transients (SEMTs) become more serious. However, SEMTs have not yet been appropriately modelled through traditional soft error rate (SER) estimation methods. Therefore, this paper presents a mixed-level framework to estimate SER induced by SEMTs. The precision of the proposed framework is verified through HSPICE simulation. The results show that multiple pulses and convergence of SEMTs significantly affect SER estimation.


The romantic idea that the speech of the first humans was in a peculiar sense poetic and then later replaced by the prosaic speech of subsequent eras was common in the eighteenth century. Vico argued that the poetic speech was a consequence of the way primitive humans appropriated nature in order to live and relate to each other. He speculated that if a primitive human were to describe in depth some contrivance such as his or her dwelling house, for example, the result would be poetry because the dwelling is constructed according to poetic (or symbolic and magical) principles (sapienza poetica) rather than the rational (or scientific) principles of modern civil engineering. The research of social anthropologists into the cultural residues of peripheral societies bears this out. Schivelbusch is up to the same sort of thing in this book but what concerns him is how the apparatus of railways contributed to translating the psychic life of human beings from the pre-industrial stage of a sapienza poetica to that of a modern industrial age, hence the title of his book, The Railway Journey. It is an attempt to specify a crucial movement in the direction of what Weber called 'the disenchantment of the world'.


Human society has at all times placed great value on beauty of the human body, but a person's perception of their own body may not correspond to society's standards.


From the red-pink encrusting marine sponge Aplysilla rosea Barrois eight spongian diterpenes were isolated. Aplyroseol-1 was shown by spectroscopic methods to be (5R*,7S*,8R*,9S*,10R*,13S*,14S*,15S*)-15,17-epoxy-17-hydroxy-16-oxospongian-7-yl butyrate (5) and aplyroseol -2 to -6 to be (6)-(10) respectively. Two lactones (11) and (12), ambliofuran and its hexahydro derivative were also identified. A steroid fraction was also isolated.


Single-case deletion diagnostics rest on a single outlier at a point in the regressor space. Residuals are basic. Our objectives are to show (i) that shifts serve to inflate or deflate stochastically the ordinary squared residuals, even for non-outlying data; and (ii) that outliers generate anomalies as doubly noncentral distributions for both outlier and influence diagnostics, these specific to a given design. Outliers account for masking and swamping, with probabilities as evaluated here. Despite wide acceptance, software support, and routine useage, these anomalies despoil meanings historically ascribed to deletion diagnostics, thus abrogating objectives traditionally cited for their use. Case studies document some misdirected and unintended consequences of their continued use in practice.


Application of multiplexed block codes (MBCs) for realizing new, flexible and versatile multiplexing is investigated. First, it is shown that modification of simple frame structure of MBC can be used for attaining hunting-free reframing for multiplexing systems. Then, it is shown that the combined use of multiple frame patterns can realize extremely simple and flexible asynchronous multiplexing system. Finally, methods for finding usable frame patterns for asynchronous multiplexing are discussed.


fever, headache, nausea and vomiting. Two days later, he appeared acutely ill and physical examination revealed mild nuchal rigidity. A lumbar puncture showed a turbid CSF, which contained 6,400 white blood cells/mm3 with a polymorphonuclear predominance, glucose 41 mg/dl (blood glucose 219 mg/dl) and protein 4 1 g/l. Gram stain showed no microorganisms. Cultures for aerobic and anaerobic bacteria were sterile. The patient was given a ten days course of cefotaxime plus metronidazole with rapid improvement. The patient was asymptomatic when discharged. No other complications have appeared after 2 months of follow-up. Meningitis is seldom reported as a complication of radiofrequency trigeminal rhizotomy in the current literature. In a review of more than 14,000 cases from 33 reports, Sweet recorded meningitis in seven patients, brief aseptic meningeal reactions in nine and temporal-lobe abscess in another two.4 Usually characteristics of these meningitis are not mentioned.5 6 Silverberg and Britt7 described a streptococcal aetiology for a case of meningitis after radiofrequency trigeminal rhizotomy. In our experience, purulent meningitis has complicated a 0 4% of all such rhizotomies performed (2 out of 504). Streptococcus mutans was recovered in one of the cases. In the other patient prior antibiotic therapy (penicillin) may account for the sterile CSF cultures. In both cases, meningitis and radiofrequency trigeminal rhizotomy are related, since the infection was detected shortly after the procedure was performed. Invasion of the CSF space by the oral flora accidentally carried on the electrode, seems the most likely mechanism for production of meningitis.' This is supported by the fact that a usual oral bacteria (S mutans) was the aetiological agent in one of the cases. However, there was no evidence of mucosal puncture during the procedures. In summary, these two cases illustrate purulent meningitis as a complication of radiofrequency trigeminal rhizotomy. Clinical suspicion of this possibility may lead to a prompt diagnosis and adequate treatment with a good prognosis. Streptococcal aetiology seems most likely.


Abstract : A survey of mechanical and impact properties for glass-reinforced polydicyclopentadiene (p-DCPD) matrix composites is undertaken to assess the suitability of the new resin system as a replacement for existing epoxy-matrix systems. The p-DCPD resin system has superior thermal stability and intrinsic fracture-toughness properties that are desirable for Army-unique applications. However, challenges in conventional processing techniques and chemical-sizing compatibility were encountered during the study. Various novel glass fibers and commercially available fabrics were infused with both p-DCPD resin and SC-15 epoxy and mechanical and impact testing performed. The key results indicate p-DCPD composites have lower mechanical and impact performance compared to SC-15 composites due to chemical-sizing incompatibility at the fibermatrix interface. Despite efforts to tweak processing and to develop compatible sizings with industry partner Pittsburgh Plate Glass Industries, the p-DCPD composites had poor interfacial bonding that manifested as significantly lower interlaminar-shear strength. The main conclusion of this study is this: Given the desirable properties of p-DCPD, a program effort should be undertaken to develop a chemical sizing that will be 100 compatible with the p-DCPD resin and allow for processing of composites that have improved or comparable structuralas well as ballisticproperties to epoxy-matrix composites.


In this study, the subacute toxicity of the heavy metal cadmium to Hippolyte inermis Leach was investigated. Subacute effects were evaluated using changes in the locomotory behavior (i.e., moving velocity and moving distance) as indicators. The locomotory activity was analyzed by means of real-time image analysis, using a video camera and a Pentium PC equipped with a standard low-cost frame grabber. For a sequence of 3000 images per treatment, where 10 shrimp were moving simultaneously, the trajectories were reconstructed as binary image sequences. The locomotory activity of the test organisms was analyzed under normal conditions (without heavy metal stress) and after application of a subacute Cd stress. Test animals were stressed by Cd of the following 3 concentrations: 1 (C1), 2 (C2), and 3.5 ppm (C3). Shrimp were exposed to the heavy metal concentrations for 12 h under static conditions. At initiation (0 h) of Cd exposure, the test animals showed a significant (p ≤ 0.05) decrease in the average swimming velocity at C3. After 3 h of Cd exposure, the median moving velocity was for the first time highly significantly (p ≤ 0.01) reduced with the 1 ppm Cd treatment.


The US nuclear power industry has not melted down to a full stop. Since the Three Mile Island accident in 1979, the Nuclear Regulatory Commission (NRC) has granted 17 operating permits for new power reactors; three units went on line last year. Even the Diablo Canyon plant in California, a longtime target of nuclear critics from coast to coast because it's near an earthquake fault line, may get the green light by summer. And the undamaged Unit 1 reactor at Three Mile Island could start up sooner. Both friend and foe agree that many of the smaller utilities should not have entered the nuclear field.


The concept that the autonomic nervous system is concerned purely with motor innervation of the smooth muscle of the viscera dates back to the last half of the nineteenth century and the work of Claude Bernard,1Gaskell2and Langley.3In recent years the antagonistic action of the craniosacral and the sympatho-adrenal systems has been intensively investigated by the physiologists and Cannon4gave it the appropriate name of homeostasis. Through this efficient and entirely automatic mechanism, the body adapts itself to the constantly fluctuating stresses and emotions of life. Without it, as Cannon has shown, life is still possible in a perfectly protected environment. But all forms of active endeavor and conflict with unfavorable reality are no longer possible. It has been known for many years that the action of this system of nerves is not under the control of the will but is under the control of the emotions. More


Objective:  Recently, attention has been attracted by the finding that overexpression of caveolin‐1 induces cellular senescence in age‐related diseases. We aimed to ascertain whether angiogenic growth factors (AGFs) can inhibit interleukin (IL)‐1β‐induced senescence in human chondrocytes by downregulation of caveolin‐1.


ABSTRACT In Who Sings the Nation-State?, co-written with Gayatri Chakravorty Spivak, Judith Butler identifies the paradox between the seemingly global decline of the nation-state and the steadfast strength of its genealogical force. According to Butler, "Arendt allows us to realise that this may also be because the nation-state as a form was faulty from the start." In the first section of the article, I focus on Butler's analysis of Israel/Palestine as a failed nation-state and seek to identify its faulty start. I propose that the nation has been masked by the race-religion constellation in the creation of the Westphalian race-state and identify this as the "faulty start" of the nation-state in European history. The term "race-religion constellation" refers to the connection or co-constitution of the categories of race and "religion" and the practice of classifying people into races according to categories we now associate with the term "religion." I contend that it is this genealogical force of the nation that frames Israel/Palestine, which was, and is, Europe's offspring, and at times its prodigal son. In the third and final section I discuss alternatives to the nation-state by means of the notion of diasporic political communities, as taken up by Butler and Paul Gilroy respectively, to assess what such communities can provide instead of the exclusionary racist binary that is the faulty start and driving force of the race-state.


Experimental studies of stopping of ion fluxes from laser-produced plasma by a low-pressure gas atmosphere are presented. A modification of the time-of-flight spectroscopy technique is proposed for the stopping cross-sectional measurements in the ion energy range of 0.1–10 keV. The application of the proposed technique is demonstrated for Sn ion stopping by H2 gas. This combination of elements is of particular importance for the development of plasma-based sources of extreme ultraviolet radiation for lithographic applications.Experimental studies of stopping of ion fluxes from laser-produced plasma by a low-pressure gas atmosphere are presented.

particularly in the biology of the nineteenth century, is a played-out force. It is Nietzsche who interests himself in the political task of avoiding that most disliked of scientific activities as Foucault sees it: the activity of investigation, of surveillance, and of containment. Foucault in that sense is an advocate of a number of tactical responses to the invasive strategies of the human sciences; an advocate of secrecy, as against statistical science; an advocate of immediate punishment as against the humanitarian impulse of a reforming judiciary and an optimistic psychiatry; an advocate of pleasure as against pointlessly accumulated knowledge. The exact nature of Foucault's politics are obscure and will no doubt remain so, but his translator has done him valuable service. Foucault's philosophy has been explicated without being appropriated. And his place as a figure whose theoretical task awaits completion will now be understood by many who may come to feel that they can now join with him, and in that sense aid the completion itself. What was it about greenhouses that appealed so much to Victorian imagery? Like a gigantic conservatory, the Crystal Palace was erected in Hyde Park as an architectural monument to Britain's domination of world trade. Not so far away, another glass dome served a similar purpose. The great Palm House at Kew trumpeted the achievements of British botany in the commercial arena, achievements that laid the foundation for a number of highly profitable and strategically important plant-based industries across the globe. Indeed, much of the wealth of the Empire originated from the Royal Botanic Gardens. Great fortunes were built on the transfer of rubber, tea, sugar, coffee, bananas, and other commodities from their native habitat to British dominions and colonies where a similar environment was combined with large pools of available labour. The gardens at Kew played a major role in advising on and supervising such transfers. By studying the horticulture, the plantation management, the harvesting, and replanting of crops, Kew's botanists made it possible to convert scientific knowledge into hard cash. Lucile H. Brockway's book The role of the British Royal Botanic Gardens takes a long cool look at the social and economic effects of such government-sponsored botany. She describes three case histories-rubber, cinchona, and sisal-in an attempt to explain the build-up of colonial industries, the flow of information and advice from Kew, and the changing social relations of the people and nations involved. …


the evocations, linguistic styles,and connotations of the "Unequal Treaties, "are central to the shaping of politi-cal perceptions, values, and strategies that pervaded the competitive politics of early Republican China. The years from1924 to 1927 is a period of dramatic changes, at that time the term the Unequal Treaties"was coined jointly by GMTand CPC. As a symbol of Chinese subjected to foreign control,this concise term awoke and is still awaking chinese collec-tive feelings about their national past and fature. Since its birth in the 1920s, the bupingdeng tiaoyue has become a keyto understanding China's dealings with foreign countries.


The implications of assuming concrete or rock to be a perfectly plastic body when determining the bearing capacity of concrete blocks or rock are examined experimentally. The strain field is experimentally determined for the indentation of a circular punch on a circular block having various block base conditions. Limit analysis is then applied to obtain upper and lower bound solutions for the standardized indirect tensile test for concrete specimens of various shapes. The predicted results are found to be in good agreement with the existing results derived from elasticity theory.

At the first hypertext conference, Hypertext'87, there was some talk that we would soon stop having special hypertext conferences, just as we do not have special conferences about, say word processors. Future conferences would be focused on various application domains and might every now and then include papers on the use of a hypertext system. On the other hand there are still conferences about e.g. databases even though they have been one of the most commercially successful and widespread applications of computers. It may be too soon to call the final outcome, but right now it seems that hypertext conferences are proliferating (almost too much, in fact).


In this paper, in order to overcome the challenges of frequency measurement in electronic reconnaissance system, the principle of fast time-sharing reception is adopted for precise frequency estimation. The 20ms in each frequency band is resided, and the conversion of 2GHz to 18GHz RF signal to intermediate frequency signal can be completed within 200ms. The digital channelization module is used to realize the threshold detection and attenuation control of signal, and the Fourier transform with decimal is carried out for the detected signal. Based on Rife's frequency-measuring algorithm, a frequency-searching algorithm based on the balance principle is proposed to optimize the Fourier transform function with decimals through Taylor series expansion and power series table lookup, which improves the frequency resolution and reduces the computation. At the same time, it it able to optimize the frequency search strategy, and the minimum value principle can be abandoned. It is efficient to find the coarse frequency search value by comparing the spectrum information corresponding to the minimum point, and turns out to be efficient to solve the problem of large frequency measurement deviation under the condition of low SNR. The theoretical simulation results show that this algorithm has higher instantaneous processing bandwidth, higher frequency measurement accuracy and stronger noise adaptability. It has good engineering application value and can provide potential effective support for electronic warfare systems.


The present paper reports d.c. conductivity measurements at high electric fields in vacuum evapo- rated amorphous thin films of (Ge.20Se0.80 )1−xPbx (where x = 0, 0.02, 0.04, 0.06 and 0.10) glassy alloys. Current-Voltage (I-V) Characteristics have been measured at various fixed temperatures. In these sam- ples, at low electric fields, ohmic behavior is observed. However, at high electric fields (E ∼ 10 4 V/cm), non-ohmic behavior is observed. An analysis of the experimental data confirms the presence of space charge limited conduction (SCLC) in the glassy materials studied in the present case. From the fitting of the data to the theory of SCLC, the density of defect states (DOS) near Fermi level is calculated. It is found that the DOS is increasing with increase in concentration of Pb in pure binary Ge0.20 Se0.80 glassy system. The peculiar role of third element Pb as an impurity in the pure binary Ge0.20Se0.80 glassy alloy is also discussed.


In the process of Higher Vocational classified examination enrollment reform, Jilin Province has adopted a diversified examination enrollment model and "cultural quality test + vocational skill test" evaluation method, and established the "vocational education college entrance examination" system. This paper analyzes the important role and practical difficulties of "vocational skill test" in Higher Vocational classified examination, studies the existing problems, and puts forward to reasonably divide the proportion of "cultural quality test" and "vocational skill test", sets diversified admission standards, scientifically sets up the assessment methods and contents of "vocational skill test", further improves the "cultural quality test + vocational skill test" evaluation method and builds a classified examination and enrollment system more in line with the characteristics of vocational education.


The cooperative behaviour of end-systems in efficiently and fairly utilizing the scarce bandwidth is of paramount significance in the best effort Internet. Not only does the uncooperative behaviour result in unfairness, but it may also induce congestion collapse. How to urge end-systems to share the bandwidth cooperatively is a problem that depends, in essence, on incentives. This study presents a novel fairness-driven active queue management (AQM)-based incentive scheme to detect and take punitive action against any uncooperative behaviour. Different from all other fairness-driven AQM schemes, the proposed scheme offers a dual-mode control function that can adaptively switch between stateless and partial-state modes in order to be scalable. The control function remains stateless at low to moderate congestion levels and maintains a partial-state when congestion becomes severe. In the stateless mode, the identification and restriction of unresponsive flows are based on a matched-drop mechanism having a dynamic drawing factor to differentially drop packets from unresponsive flows. In the partial-state mode, a fair-share is estimated and flows whose arrival rates exceed the fair-share bandwidth get their rates limited to the fair rate. Simulation results demonstrate the reasonable performance improvement of the proposed scheme over well-known fairness-driven AQM schemes.

Reaction of amines and phosgene at low temp, for conversion of the amino group into carbamyl chloride and amine hydrochloride, and further reaction of this at high temp, with phosgene is known so-called Cold-Hot Method for synthesis of isocyanate. In case diamine such as TDA is used, a high molecular urea compound is formed by the wrong procedure of reacting condition and precipitated, so that the reaction with phosgene becomes difficult, resulting considerable decrease in the reaction velocity and yield. For successful operation of this reaction, it is necessary to make sufficient contact of phosgene with TDA in low temp. reacction in order to decrease the amount of unreacted TDA in the product and sufficient supply of phosgene in high temp, reaction. It is desirable to use solvents, such as ketones, esters and ethers, having high solubilizing power of low temp. reaction product. Also, chlorobenzene, dichlorobenzene, etc. could be used as the solvents by adding TDA solution into phosgene solution with vigorous stirring, in order to give finely dispersed particles of low temp, reaction product. The high temp, reaction is completed in 30 min at 130°c by sufficient introduction of phosgene in the low temp, reaction product thus obtained and the yield is high.


TiO_2/SnO_2:F composite films were deposited by atmospheric pressure chemical vapor deposition with Ti(OC_3H_7)_4 as pre- cursors and SnO_2:F coated glass as substrates.According to the results of scanning electron microscopy,X-ray diffraction,and ultra- violet-visible-near infrared transmission spectroscopy,the formation of rutile TiO_2 can be promoted by the insertion of the rutile SnO_2:F under layer.When the substrate temperature is 480℃,a needle-like structure appears in TiO_2/SnO_2:F composite films,and then disappears as the temperature increases.The optical transmittance in the visible region varies from 60% to 90% with the change of substrate temperature,and is suitable for the daylight demands of buildings.TiO_2/SnO_2:F composite film prepared at the substrate temperature of 530℃has the best photocatalytic properties.


Automated Optimal Design (AOD) of electromagnetic devices turns out to be a task of increasing significance in the field of electrical engineering. Recent developments offer the opportunity to attack realistic problems of technical importance. The distinctive feature of this type of problem is its complexity which results from a high number of design parameters, a complicated dependence on the quality of design parameters and various constraints. Often the direct relation of desired quality of the technical product on the objective variables is unknown. Stochastic optimization methods in combination with general numerical field computation techniques like the finite element method (FEM) offer the most universal approach in AOD. The paper discusses methodology, characteristic features and behaviour of the methods used. The application to a nonlinear magneto-static problem of technical significance is demonstrated by minimizing the overall material costs of a small de-motor by optimizing the rotor and stator shape. INTRODUCTION Numerical optimization methods have to be examined with regard to the following criteria: • reliability • robustness • insensibility to stochastic disturbances • application range Transactions on the Built Environment vol 2, © 1993 WIT Press, www.witpress.com, ISSN 1743-3509 16 Optimization of Structural Systems • accuracy • performance Stochastic methods are known to fulfil the above mentioned requirements. A main advantage is their insensibility to stochastic disturbances of the objective function caused by numerical evaluation [2]. This insensibility is a consequence of non deterministic search and disuse of derivatives. A second important property is the easy treatment of constraints. Hence a complicated transformation into an unconstrained problem formulation is not necessary. To solve the nonlinear field problem a suitable method of wide application range has to be chosen. Here field calculation is accomplished by the FEM. Error estimation, adaptive mesh generation and refinement are used. This method guarantees the greatest possible facility in modelling and allows optimization without severe geometrical restrictions. OPTIMIZATION METHOD Optimizing requires the concentration of all design aims into a single function Z(x). This function depends on all design parameters and represents the quality of the specific design. The function is called objective function. Additional constraints G;(x) limit the admissible parameter variation. The general problem class to be considered is the nonlinear constrained optimization and may be expressed in mathematical terms as: Z(x) = Z(zi,Z2,...,zJ -> Min. (1) with independent variables x = {x, : i = l(l)n} in the space x e JR^ and j = 1(1)77% constraints, t \ OXx) = G;(zi,Z2,...,zJ = 0 (2) Random based search methods only evaluate the objective function itself without use of derivatives. Using numerical methods the dependence of the quality function on the objective parameters is not available in explicit form and may be very complicated. The numerical calculation of derivatives may become troublesome as well due to discretization and cancellation errors. A further uncertainty occurs from inexact objective function evaluation. So, the simplest and most reliable procedure is to use stochastic search methods for optimization. Transactions on the Built Environment vol 2, © 1993 WIT Press, www.witpress.com, ISSN 1743-3509 Optimization of Structural Systems 17 Random variations of the objective variables x, is done by the rules of evolution strategy. The introduction of the control parameter temperature in the search process aims to avoid the system getting stuck in a local minimum. Barriers of height kgT, where ks is the BOLTZMANN constant and T the temperature, can be surmounted on the way to a better solution. The evolution strategy, a Monte-Carlo method, copies the natural principles mutation and selection (survival of the fittest) of biological evolution into the technical optimization problem. The basic concept of the evolution strategy is found in the substitution of DARWIN'S notion of fitness to the quality of a technical problem. The driving force in the optimization process is the repetition of mutation and selection in successive steps. RECHENBERG [5] transformed the scheme of biological evolution into a simple algorithm. This elementary form is termed the (l + l)-strategy. One parent (valid solution vector) generates a descendant, which differs by mutation of the objective variables from the parent. After evaluation of the objective function the parameter vector with the better quality is chosen to form the parent of the following generation etc.. Based on the (l-fl)-strategy more general and powerful strategies were introduced by SCHWEFEL [6]. To illustrate the simplicity and its universal applicability fig. 1 shows a scheme of an extended algorithm. The mutation of the objective variables of an initial generation of valid parameter vectors (parents) leads to a number of children. The variables of one child may depend on multiple parent variable vectors as indicated in fig. 1. The best children are selected to form the next parent generation. If is the number of parents, A the number of children and p a hereditary factor the strategies can be distinguished in the following manner. \r~ , • -y ^ — — o»/ The population of the next generation is selected from parents and A children. (/.t, A)-comma-strategy: The population of the next generation is selected from the /.i best children. Parents only live for one single generation. (—h A)-strategy: p p parents contribute to the creation of a child (p-sexuality). ^ of the hereditary factor of one parent is transferred to a child. • (-, A)-strategy: p comma-variant of the last mentioned strategy.

The confocal scanning microscope (CSM) is becoming a powerful imaging modality in dermatology and otolaryngology, because of its optical sectioning capability which allows us to noninvasively image thin sections of in vivo tissue with high resolution and contrast. The CSM provides a window into living tissue for basic and clinical research; it potentially offers doctors an imaging diagnostic which operates in real-time and is entirely noninvasive compared to conventional biopsy-based histopathology [Pierard, 1993]. High-resolution imaging of skin in vivo has been achieved with a white light tandem scanning confocal microscope [New et al., 1991; Corcuff and Leveque, 1993; Corcuff et al., 1993; Bertrand and Corcuff, 1994] and our confocal scanning laser microscope (CSLM) [Rajadhyaksha et al., 1995]. We recently optimized our CSLM for improved resolution and contrast. Our clinical imaging-and-analyses studies of the past year include (i) fifty pathologic human skin lesions, (ii) effects of ultraviolet-B irradiation on the skin, and (iii) normal and pathologic oral cavity tissue. In this paper, we present optimum CSLM parameters for imaging living skin and oral tissue, and the results of our clinical imaging work.


The typical operation conditions in Scanning Electron Microscopy have changed a lot during the last two decades. Imaging of insulating layers or biological samples demand for the use of low electron energies and currents. These conditions are not only challenging for the microscope itself but also for their detection systems. Many currently used Backscattered Electron (BSE) detectors show a highly reduced quantum efficiency for electron energies smaller 5 keV. This decreases the image contrast and signal to noise ratio and the necessary high gain of the readout electronics limits the detection speed. However, there are ways to increase the collection efficiency and the bandwidth of BSE detectors and therefore improve the detector performance.


A new method of high-level test generation for control faults in digital systems is proposed. High-level faults of any multiplicity are assumed to be present, however, there is no need to enumerate them. A novel concept of test groups which has the goal to prove the correctness of a part of the system's functionality instead of keeping track of fault coverage during test generation as in the traditional case is elaborated. The method can be regarded as a generalization of the logic level test pair approach for identifying fault-free wires in gate-level networks to a high-level identification of fault-free functional blocks. To cope with the complexity of multiple fault masking mechanisms, high-level decision diagrams are used. A method for optimizing test length was developed with no negative impact on the immunity regarding possible fault masking, and the estimates of the gain in test length were given.


Since 1964 the author, who is Game Warden of Sabah (formerly British North Borneo) has been running a state-supported orang utan rehabilitation project in the Sepilok Forest Reserve. Most are confiscated animals, having been kept illegally, often as pets, and he describes some of the difficulties in getting them to become independent again and able to live in the forest. Some have even been too well treated in captivity, living luxuriously and treated like humans.


The utility model relates to the technical field of vehicles, in particular to a braking system. A disc-free braking system comprises a driving shaft, the driving shaft is connected with a braking device, the braking device comprises a generator, the rotor of the generator is in transmission connection with the driving shaft, the power output end of the generator is connected with an energy storage element, and a current control module is arranged between the energy storage element and the power output end. Due to the adoption of the technical scheme, the disc-free braking system carries out braking through electronic control, and has the advantages of wear resistance, long term validity in braking, energy conservation, braking accuracy and the like.


High liquefaction temperature and greenhouse effect are two major problems of SF<inf>6</inf>. To find alternative gas of SF<inf>6</inf> becomes an urgency in power industry. In this paper, the insulation characteristics of c-C<inf>4</inf>F<inf>8</inf>/N<inf>2</inf> are studied. The AC breakdown voltage in slightly non-uniform electric field with different air pressure and mix ratio is measured. The results show that breakdown voltage increases with the increase of the pressure and the proportion of c-C<inf>4</inf>F<inf>8</inf> within the range of experimental conditions and c-C<inf>4</inf>F<inf>8</inf>/N<inf>2</inf> has considerable insulation properties as compared with SF<inf>6</inf>. In addition, the mixtures gas after breakdown is detected. C<inf>2</inf>F<inf>4</inf>, a new decomposition product, is found. Results in this paper provide a reference for the practical application of c-C4F8/N<inf>2</inf> mixturess in power industry.


The overall objective of this work is to develop, test and evaluate a computer
assisted analysis algorithm to help the groundwater professional identify, at least
cost, the location of a DNAPL source. The DNAPL source location is generally too
small to identify via borings or geophysical methods. On the other hand, the plume
emanating from a DNAPL source is typically quite large and easily discovered. The
algorithm presented here defines how to achieve an acceptable level of
source-location accuracy with the least possible number of water quality samples.
The overall strategy includes the construction of a stochastic groundwater flow and
transport model assuming a number of potential locations of the DNAPL source. Each
location is associated with an initial weight that reflects our confidence that it is
the true source location. This is done using a Choquet integral. The hydraulic
conductivity is considered the main source of uncertainty, other than the source
location, and the Latin hypercube sampling strategy is used to obtain the hydraulic
conductivity field. Using the hydraulic conductivity field and the uncertain source
location weights as input to the groundwater flow and transport simulator, the
concentration random field and its associated uncertainty is calculated. An optimal
sampling point is selected using a method that combines the minimization of the total
field variance and the proximity to the potential source locations. A Kalman filter
is used to update the simulated concentration field using the real data and the
updated plume is compared to the individual plumes (that are calculated using the
groundwater flow and transport simulator considering only one source at a time) using
a method that involves representing the normalized concentrations as fuzzy sets and
comparing several of their α-cuts. The comparison provides new weights for each
potential source location that are used as input to the groundwater flow and
transport model and the above steps are repeated until the weights stabilize and the
optimal source location is found.
The algorithm has been successfully tested using synthetic example problems that
include homogeneous and heterogeneous aquifers, a pumping well, multiple true DNAPL
sources, two dimensional and three dimensional problems. A field application is
considered as another test of the proposed algorithm.


Whereas the professional practice of medical laboratory science generates a number of ethical issues, hardly have these been given due attention. Employing two cases, this paper attempts to highlight how professional obligations may conflict with but over-rule real or perceived obligations of laboratory scientists to families/friends in the context of diagnosing two infectious diseases: the human immunodeficiency virus (HIV) and syphilis.


The aim of the paper is to provocatively draw comment from practising enterprise educators to acquire
multiple perspectives of who is currently teaching enterprise education. The paper aims to introduce
the issue of student diversity into the current debate of how enterprise education should be delivered.
An initial taxonomy of approaches to delivering enterprise education is conceived for comment from
educators and their initial comments are considered. The preliminary conclusions are discussed with
suggestions for future research directions.


Progressive necresis of the mandible is often seen as an undesirable condition after a radiation therapy of malignant lesions in or near the oral cavity. It has been believed that the possibility of this complication is decreased by the preliminary extraction of the teeth that are located in the irradiation area. This opinion, however, is not universal and some radiotherapists have advocated to keep the teeth in the irradiation area. Recently, many inverstigators believe that an extraction of the teeth before a radiation therapy reduces the radiation hazard. Both opinions on the radiation hazard for mandible mainly consist of clinical impressions. There are few experimental studies on the radiation hazard which were performed to evaluate the difference between the dentulous mandible and the edentulous mandible. A series of experiments were clesigned to know the influence of the teeth on the


By using the precipitation data of Integrated Automatic Meteorological Station,actual area rainfall is calculated based on Tyson polygon method over Fuhuan river valley.The arithmetic average of area rainfall productions of T213、GRAPES、MM5、JAPAN and GERMANY on the grid is as the forecast factor.24 hours and 48 hours area rainfall forecast is made by means of the Gray Forecast Model GM(0,h).During the operation application in the main flood season from June to August in 2007,composite score TS of area rainfall rainstorm forecasting are 52.0% for 24 hours and 40.0% for 48 hours.


Tertiary amine catalyzed reaction of imines with phenacyl bromide derivatives expeditiously affords functionalized aziridines in high yields and stereoselectivities in a one-pot process. Advantageously, the protocol precludes the preparation and isolation of ylides and their precursors in a separate step as they are formed in situ.


We have obtained some more details about the electron and intense laser interaction by calculating the exact waveforms of the radiation field. We have shown that the radiation polarization from the nonlinear Thomson scattering does not follow the laser polarization, but changes with the laser intensity, which could be used for measuring high laser intensities. We have also shown that the actual pulse width of the x-ray generated by a relativistic inverse Compton scattering is in the attosecond region due to the relativistic retardation effect.


Lupinus mariae-josephi is described as new from Valencia (Spain). The new species differs from any other Mediterranean and North American taxon in banner position, flower colour and inflorescence structure.

An important aspect of research on software objects, components, and component-based applications concerns their interoperation. Is their interoperation technically possible? Which elements are responsible for the software objects' incompatibility? Is compatibility a responsibility of the objects or of their underlying architectures? In this article we discuss the object compatibility problems, we describe basic strategies for bridging the gap between the three basic middleware remoting technologies (CORBA, DCOM, and RMI), and present our approach for a Java-based Object Mediator architecture.


The Visible Infrared Imaging Radiometer Suite (VIIRS) is one of the instruments included in the National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP), which is a joint mission between NASA and the NPOESS Integrated Program Office (IPO). The NPP provides a bridge between the current Earth Observing System (EOS) and future NPOESS missions by testing the pre-operational on-orbit system and providing risk reduction for key NPOESS instruments. The VIIRS exploits design concepts of advanced sensors, such as the MODerate Resolution Imaging Spectroradiometer (MODIS), and development of data products on the NASA EOS. It is designed to provide continuity of global observations of land, ocean, cloud, and atmospheric parameters, called Environmental Data Records (EDRs), for real-time meteorological operations and long-term climate change research. This paper provides a brief overview of the VIIRS instrument on-orbit radiometric calibration and characterization activities supported by the NASA NPP Instrument Calibration and Support Element (NICSE). The NICSE is part of the Science Data Segment (SDS) within the NASA NPP program. This paper focuses on the capability and responsibility of NICSE, the tool development for post-launch calibration, and activities to assess sensor performance through the use of its On-board Calibrators (OBCs), as well as to independently verify the quality of VIIRS Sensor Data Records (SDRs).


Mining is a fundamental economic activity that sustains basic sectors. In abandoned sand mines, the natural vegetation recovery is very slow and in many cases, the recolonization may take decades before the organic material and the soil structure are restored. To minimize this impact, the law requires restoration of native vegetation. In this paper, we evaluate the structure of the vegetation after nine years of planting in an area degraded by sand mining. We recorded which of the species better established in the area. All tree individuals with DBH > 2.0 cm had DBH and height recorded and were identified. The number of species was slightly higher (7.5%) than the number used in planting. Over 70% of those are early successional species. Four species showed individuals over 6 m in height after nine years of planting and are recommended for future recovery plantations. The most successful species was of the early stages of succession.


Based on an anti-pulling test of the prestressed concrete pipe pile in which the reinforcement stressometers were pre-buried,the load bearing mechanism and the axial force calculation method of PHC pipe pile under the anti-pulling action were analyzed.Some suggestions for design and construction were proposed.


AbstractWe derive the general upper bounds on the mass of the lightest neutralino, as afunction of the gluino mass, in different supersymmetry breaking models with minimalparticle content and the standard model gauge group. This includes models withgravity mediated supersymmetry breaking (SUGRA), as well as models with anomalymediated supersymmetry breaking (AMSB). We include the next-to-leading ordercorrections in our evaluation of these bounds. We then expand the mass matrix inpowers of M Z /µ, and find the upper bound on the mass of the lightest neutralinofrom this expansion. By scanning over all of the parameter space, we find that thebound we have obtained can be saturated. We compare the general upper bound onthe lightest neutralino mass to the upper bound that is obtained when the radiativeelectroweak symmetry breaking scenario is assumed. PACS number(s): 12.60.Jv, 14.80.Ly 1 Introduction It is widely expected that at least some supersymmetric particles will be produced at thelarge hadron collider (LHC) that is starting operation in a few years' time. However,most of these supersymmetric particles will not be detected as such, since they will decayinto the particles of the Standard Model (SM), or to the lightest supersymmetric particle(LSP), which is stable as long as the R-parity is conserved. Thus, the experimental studyof supersymmetry involves the study of cascade decays of the supersymmetric particlesto the LSP and the reconstruction of the subsequent decay chains. The LSP in a largeclass of supersymmetry breaking models is the lightest neutralino, which has thus been asubject of intense study for a long time [1, 2, 3, 4, 5, 6]. A stable lightest neutralino is also1


Until the publication of these books,* the motor industry in Ireland was remarkable among other reasons for the fact that there had been no full-length publication on any aspect of its history, development or structure. The works of Moore and O'Donovan were therefore awaited with impatience. That of O'Donovan in particular was spoken about with great expectations for a number of years prior to its appearance. While to some extent filling the gap, both books nevertheless leave much ground to be covered.

The diagnosis of mental and personality disorders or serious potentialities for their development has resulted in the rejection of more Selective Service registrants than has any other defect. It must be understood that by mental and personality disorders is meant any variation in the emotional capacity of the individual to adjust to his situation which results in symptoms indicating, in this instance, the possibility of maladjustment to military life. 1 Among white registrants no other defects approach mental and personality disorders in importance as a cause for rejection, while for Negroes they are exceeded only by mental deficiencyand syphilis. In addition, mental and personality disorders have accounted for more disability discharges from the armed forces than any other defects. The standards for the rejection or acceptance of men for military service have been the responsibility of the armed forces. Most of the rejections for mental and personality disorders have


The present study investigated the Thiamin deficient in male wistar rats. Male albino rats weighing between 150-200 gm were used. They were divided into two groups and allowed to acclimatize to the new environment conditions of our laboratory for one week before use. They had free access to food and water. The standard group animals were received specified diet (Control rats) (C groups). This provides them the essential dietary requirements. The test animals received polished rice and drinking water was made available to animals all the time. The Serum glutamate oxalo acetate transminase (SGOT), Serum glutamate pyruvate transminase (SGPT), Total protein, Albumin, Serum cholesterol Serum Triglycerides Blood urea, Hemoglobin, High density lipoprotein (HDL) and rectal temperature of the rats were determined in serum, body weight and temperature recorded every alternative day. In the present study, the thiamin deficient rats showed the increased levels of SGOT, SGPT, pyruvic acid, total protein, Blood urea Hemoglobin, Serum triglycerides Serum Cholesterol and decreased body weights, HDL, Albumin and rectal temperature when compared with the normal diet received rats. Thiamin deficiency is due to excessive washing of rice, and low intake of fruits and vegetables.

Poor and inconsistent diagnosis of asthma is one main reason for the burgeoning cases of death from asthma. On top of that, the nature of current diagnosis methods being invasive and unpleasant limits their applicability. Hence the identification of biomarkers to non-invasively and conveniently detect asthma will facilitate interventions to prevent disease progression. Whole saliva may be analysed for the diagnosis of asthma, since it can be readily collected and contains identifiable serum constituents. The purpose of this study was to characterize the human salivary proteome in asthmatics of different severity to identify potential biomarkers. By using proteomic approaches such as 2D gel electrophoresis and Bioplex. We found 11 potential candidate markers whose levels were significantly different. These 11 proteins include Cystatin S, Cystatin SA, Cystatin SN, Cystatin SA-III precursor, Cystatin D precursor, Calgranulin B, Zn-Alpha2-glycoprotein, Prolactin-Induced Protein, Alpha Amylase, IL-1 beta and IL-8. These techniques identified candidates that may prove to be of diagnostic significance. This is followed by investigation of individual samples via Dotblotting where we have discovered proteins (Calgranulin B, Lactoferrin and Complement 4) with diagnostic potential, all having AUC of 0.8 and above. Further large scale and quantitative work have to be done to conclusively conclude their diagnostic utility for clinical use.

Western blotting readily identifies specific proteins amidst complex biological backgrounds[1, 2]. Nevertheless, immunoblotting suffers from tremendous labor-intensive and time-intensive requirements [3]. The slab-gel assays require 1-2 days for completion with multiple hands-on "blotting" steps and yield semi-quantitative information. Recently, our group has introduced new approaches for completing Western blotting. The microfluidic integration strategies introduced and used allow rapid results reporting, full assay automation, and limited sample consumption (1-10 uL). Our integration strategies use spatial, temporal, and spatiotemporal modulation of separation mechanisms in fully electrophoretic systems. The present study reports on recapitulation of immunoaffinity in previously sized proteins, using novel in-transit electrophoretic removal of SDS from SDS-protein complexes. Early results show both the length- and timescales for protein "renaturation" are compatible with on-chip operation. Further, substantial binding affinity is recapitulated using this streamlined and promising approach.

Non-toxic indium phosphide (InP) quantum dots (QDs) were synthesized by the solvothermal method and then embedded into dental resin to tune the emission color of the resin. Cell viability was investigated with a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and a reactive oxygen species (ROS) assay to evaluate biological applications. The results clearly indicate that employing InP QDs in creating dental resin composites allows for the fabrication of restorative materials with biocompatible fluorescence properties.


Little quantitative data are available on territorial behavior of female lizards. In this study, I examined territorial establishment and maintenance behavior of a population of female tree lizards (Uro- saurus ornatus) in southern New Mexico. The clusters of boulders that the lizards inhabit were mapped and scan sampled twice a day through the entire activity season (February-October) and the placement of each lizard noted. Mapping data suggest that the females establish and maintain territories throughout their activity season. Female territories do not overlap with their nearest female neighbor during the peak repro- ductive period and are always within a single dominant male's territory. Focal animal observations were also performed throughout the entire activity season to ascertain if seasonal changes in time budgets occur. Reproductive condition was noted for each female during focal observations as pre-reproductive, reproduc- tive (gravid), and post-reproductive. The seasonal focal animal data reveal that females perform significantly more social behaviors when they are gravid. These data detail changes in female lizard behavior over a long term territorial study.


This paper presents a model of campaign contributions where a special interest group can condition its contributions not only on the receiving candidate's support but also on that of her opponent. This allows the interest group to obtain support both from contributions as well as from the implicit threat of contributing to the opponent. These out-of-equilibrium contributions can help explain the "missing money" puzzle in the empirical literature. Our framework contradicts standard models in predicting that interest groups do not give to both sides of a same race. It also predicts that stronger candidates get more money from special interest groups primarily because more contributors give to lop-sided winners, not because more money is given per contribution. Both of these predictions are strongly supported in FEC data for U.S. House Elections from 1984-2004. Our theory also predicts that special interest groups will mainly target lop-sided winners whereas general (partisan) interest groups will contribute mainly to candidates in close races. This is also verified empirically. Finally, our framework implies that stricter campaign finance rules will always lower special interest influence but may lead to an increase in equilibrium contributions, making the latter a poor measure of effectiveness.


This paper explores how changes in monetary staff incentive contracts affect the productivity of credit officers within microfinance institutions. The study uses a unique data set from five microfinance institutions that includes productivity data at the credit officer level for several months before and after a change in the incentive schemes. In each of the institutions, the monetary incentives were increased from a relatively weak-powered scheme to a moderately strong-powered scheme. The effects were quite significant on various measures of productivity but were notably heterogeneous across tasks, individuals, branches, and institutions. The results are consistent with an expanded principal-agent framework that also accounts for noncontractible differences in local market conditions.


SUGARCANE stem borer, Chilo infuscatellus is the most devastating pest, causing huge economic losses in the sub-tropics and therefore requiring effective management strategies. The current research was conducted to study the biology and management of C. infuscatellus. Moreover, we checked the efficacy of Trichogramma chilonis and granular insecticides against this key pest. Theincubation period for C. infuscatellus was 2.30 days, with a total developing time of 23.30 days for the larvae and 5.90 days for the pupa. Male and female C. infuscatellus had a 36.80-day and 38.00-day total life span, respectively, with the female living longer (4.8 days) than the male (3.90 days). The total female fecundity was 315.90 eggs with a 90.87 egg hatchability rate. The mean percent parasitism (87.01%) and percentage of adult emergence (76.11%) of T. chilonis on C. infuscatellus were both very high, with a total developmental time of 8.74 days in laboratory environment. Additionally, there were notable differences between the findings on the effectiveness of granular pesticides and T. chilonis in the field. The plot treated with Fipronil had the least mean percent infestations (3.58%), followed by Carbofuran (4.26%), and T. chilonis (5.63%). The control plot had the highest mean incidence of infestations (13.34%). Future IPM initiatives should incorporate the introduction of Trichogramma or the utilization of Fipronil @ 16 kg ha-1 for the treatment of C. infuscatellus. This practice will play a critical role in environmental protection and natural resource conservation against insecticides.


A high power multi-pulse modulator was presented which could generate three pulses with adjustable interval on the fieldemission diode.In the system,a pulse transformer was employed to upgrade the discharging voltage of three groups of capacitors and charge the Blumlein pulse forming line.When the main gap being closed at interval of a certain time,three pulses were obtained on the field-emission diode,the peak power of each pulse was over 20 GW,pulse duration about 80 ns,and pulse interval about 15 ms.The simulation results agreed well with the experimental results.The experimental results showed that the recovery time of the main gap was an important effect factor on the pulse interval of the modulator.


Product sound quality has a significant role in buying decision and customer satisfaction. An often used method to assess the sound quality of any product or equipment is a subjective listening test where the sound is heard by a panel of subjects (jury) who then rate the sound quality. Subjects use a semantic differential rating wherein they evaluate the presented sounds based on a bipolar variable. The two extremes of the rating scale are labeled with an adjective and its antonym respectively. In the present study, a subjective listening test has been conducted to assess sound quality of automotive horns. The data obtained are then analyzed using statistics to gain insights. Twenty two horn sound samples were judged by thirty participants aged 20-40 years who had normal hearing. Binaural head set (BHS) instrument was used to record horn sound samples in open ground (neglecting wind noise effect). Sounds are recorded two meter from horn in front direction and used for subjective test. For the subjective test and subsequent statistical analysis, a four step procedure has been used. In the first step, the participants were asked to rate the sound quality for each horn based on seven bipolar variables. These bipolar variables are soft/loud, calm/frightening, slow/fast, relax/tense, safe/danger, vague/distinct and pleasant/unpleasant. For each bipolar variable, a seven verbal interval scale was used ranging from one extreme to another in degree, for example extremely pleasant to extremely unpleasant.


Objective To observe the distribution and drug resistance of pathogens from patients with chronic varicose ulcer of leg in vascular surgery department and provide scientific basis for clinical rational medication.Methods The distribution and drug resistance of pathogens from patients with chronic varicose ulcer of leg in vascular surgery department from January 2012 to December 2013 were retrospectively analyzed. Results The pathogenic bacteria were widely distributed and the most common bacteria were Staphylococcus aureus and Pseudomonas aeruginosa. Staphylococcus aureus were highly resistant to Penicillin G( 97. 37%),Erythromycin( 60. 53%) and Clindamycin( 66. 26%),while sensitive to Linozulam and Vancomycin. Pseudomonas aeruginosa had a high sensitivity to antibiotics. Conclusion The pathogenic bacteria from patients with chronic varicose ulcer of leg were widely distributed and likely to cause multiple infections. The clinical medication should be based on the antimicrobial susceptibility test results,while individual and systematic treatment should be taken for different patients in order to improve the cure rate and reduce the recurrence rate.


A new approach based on morphological operators is presented for identification of individuals by segmentation and analysis of the iris. Several morphological operators are developed to segment the iris region from the eye image and also to highlight chosen iris patterns. The extracted features are used to represent and uniquely characterize the iris. In order to properly extract the desired patterns, we also propose an algorithm to produce skeletons with unique paths among end-points. This new representation, obtained by the proposed morphological operators is stored for identification purposes. Results are presented to illustrate the efficiency of the identification system. The proposed system was derived to present low complexity implementation and low storage requirements.


Broadband network analysis measurements can simplify on-wafer device and subsystem modeling (and related) efforts by minimizing setup changes and calibration cycles. Instrument coverage from low frequencies to 220 GHz has been recently presented but, as important, are the probes and the calibration and measurement characteristics. Broadband probes based on a single coaxial interface are presented along with basic measurement and calibration repeatability data based both on LRM and mTRL calibrations using transmission lines and symmetric attenuators as the primary DUTs. The process was exercised at low drive levels as might be required in active device characterization and the results show controlled repeatability and drift behaviors largely consistent with signal-to-noise ratios.


The density and geometry of ¯ p and e + plasmas in realistic trapping potentials are required to understand and optimize antihydrogen ( ¯ H) formation. An aperture method and a quadrupole oscillation frequency method for characterizing such plasmas are compared for the first time, using electrons in a cylindrical Penning trap. Both methods are used in a way that makes it unnecessary to assume that the plasmas are spheroidal, and it is shown that they are not. Good agreement between the two methods illustrates the possibility to accurately determine plasma densities and geometries within non-idealized, realistic trapping potentials. © 2007 Elsevier B.V.

A Dirichlet-Neumann representation method was recently proposed for upscaling. The method expresses coarse fluxes as linear functions of multiple discrete pressure values along the boundary and at the center of each coarse block. The number of pressure values can be adjusted to improve the accuracy of simulation results, and in particular to resolve important fine-scale details. Improvement over existing approaches is substantial especially for reservoirs that contain high permeability streaks or channels. Multiscale methods obtain fine-scale fluxes or pressures at the cost of solving a coarsened problem, but can also be utilized for flexible upscaling. We compare the DNR and a multiscale mixed finite-element method. Both can be expressed in mixed form, with local stiffness matrices obtained as inner products of basis functions with fine-scale subresolution determined from local flow problems. Piecewise linear Dirichlet boundary conditions are used for DNR and piecewise constant Neumann conditions for MsMFE. Adding discrete pressure points in the DNR method corresponds to subdividing coarse faces and hence increasing the number of basis functions in the MsMFE method. The methods show similar accuracy for 2D Cartesian cases, but the MsMFE method is more straightforward to formulate in 3D and implement for general grids.

In this paper, blind separation and deconvolution (BSD) problem with binaural-sound mixtures is addressed. We have proposed two-stage blind separation and deconvolution algorithm, which consists of Single-Input Multiple-Output (SIMO)-model-based ICA (SIMO-ICA) and blind multichannel inverse filtering. In the previous report, we carried out simulations in the artificial mixing system and only showed that the proposed BSD can work theoretically. In order to evaluate the proposed method in more actual situations, we carried out BSD experiments assuming that speech sources are convolved with head related transfer functions (HRTFs). The simulation results reveal that the proposed BSD method can be effective in the separation and deconvolution even with binaural-sound mixtures.


During Beiwei dynasty,the funeral reformation was one part of the Hanization carried by Emperor Xiaowen.The funeral reformation consisted of the recovery of the Three-year mourning system,adding some measures taken by Han-Jin dynasty,adopting the rite of being present three times during the funeral.In addition to these measures,Emperor Xiaowen also regulated the funeral of the people who had moved to Luoyang and those who should mourn for their owners etc.The Funeral Reformation strengthened the Hanization reformation,made the filial piety ideas rooted into Beiwei's people,and improved the society of the Bei-wei dynasty.

In his textbook in macroeconomic theory, Ferguson (1966, pp. 197-204; 399402, 432-34) approaches the producer's demand for factors in a way which seems pedagogically fruitful in that the analogy with the consumer's demand for consumer goods becomes clear. According to Ferguson the total effect of a change in the price of a factor can be split into a "substitution effect", an "output effect" and a "profit-maximizing effect". The first two of these effects correspond to the substitution and the income effects in the theory of consumer behavior, but the third effect is specific to the theory of the firm. However, Ferguson never explicitly identified the profit-maximizing effect, nor did he discuss its direction.' The objective of the present note is to fill in this void.2 Obviously, the problem of maximizing utility subject to a budget constraint corresponds to the problem of maximizing output under a cost constraint. Consequently, the "Slutsky-relationship" must hold, i.e. we can split the effect on factor demand of a change in factor price into a substitution effect (showing the effect on factor demand when output is held constant) and an output effect (showing the effect of the cost compensation that would be necessary to keep output constant):


Abstract : Civilian trauma centers and military combat support hospitals have evolved to treat increasingly severe injury. Today, they routinely save patients whose care would have been futile two decades ago. The most important advance has been an approach called damage control surgery in which the restoration of normal anatomy is deferred to limit the progression of coagulopathy. This technique has been developed to the point that it has outstripped conventional blood bank support. Uncontrolled coagulopathic hemorrhage is now the major cause of potentially preventable death following trauma. Roughly 1 in 10 people in the United States is brought to or seeks medical care for injury each year. One in a 100 is hospitalized, and approximately 1 in a 1000 receives blood products as part of the acute treatment of injury. At the University of Maryland Shock-Trauma Center (UMSTC) in calendar year 2000, 8 percent of 5649 injured patients admitted directly from the scene of injury received RBCs during their hospital stay, 5 percent received plasma, 3 percent received PLTs, and 0.1 percent received cyroprecipitate.

SWOT analysis, based on the facts established in the socioeconomic analysis, is a significant component of the practical part. Findings of the SWOT analysis are used for the proposal of the further development of the city.


We study the changes in the dielectric constant as a function of temperature on Rb/sub 2/ZnBr/sub 4/ single crystals after irradiation with 22-MeV /sup 2/H/sup +/ and 108-MeV /sup 32/S/sup 9 +/ ions. Near the commensurate-incommensurate transition our results are interpreted in terms of the nature and amount of defects introduced by the particle irradiation. We observe an anomaly in the dielectric constant in virgin and irradiated samples;we relate it to the temperature dependence of the incommensurate wave vector


This paper develops an information-theoretic understanding of side information in control systems. We build on the notion of "control capacity" - the rate at which a controller can dissipate uncertainty in a system over an actuation channel - and quantify the change in control capacity due to side information. The results build on the bit-level carry-free models that are widely used to understand information flows in wireless network information theory. These models motivate our definitions and theorems. We show that we are able to compute the value of side information for real i.i.d. actuation channels using a simple conditional expectation. Finally, we give an example of how side information affects the control capacity of an actuation channel with a uniform distribution.


In order to meet the demand of special high quality servo motor and driver in robot industry, the control system of industrial robot is briefly introduced. On the basis of the ordinary servo control system, proportional resonant (PR) control technology is introduced to improve the control performance of the system. In order to verify the dynamic characteristics of the robot system after introducing PR control technology, the Simulink module was used to build the robot model, and kinematics simulation was carried out. The results show that the robot control system with PR control technology has better control effect and dynamic characteristics than the ordinary servo control system.

Pre-trained speech encoders have been central to pushing state-of-the-art results across various speech understanding and generation tasks. Nonetheless, the capabilities of these encoders in low-resource settings are yet to be thoroughly explored. To address this, we conduct a comprehensive set of experiments using a representative set of 3 state-of-the-art encoders (Wav2vec2, WavLM, Whisper) in the low-resource setting across 7 speech understanding and generation tasks. We provide various quantitative and qualitative analyses on task performance, convergence speed, and representational properties of the encoders. We observe a connection between the pre-training protocols of these encoders and the way in which they capture information in their internal layers. In particular, we observe the Whisper encoder exhibits the greatest low-resource capabilities on content-driven tasks in terms of performance and convergence speed.


The structure and microstructure of soil burned and unburned from Yang Mausoleum of the Han Dynasty is observed by SEM and 3D-MSD. Then the quantitative calculations of microstructure are measured by IPP software in photos. The results showed that fire had a significant effect on microstructure of soil. After the soil was burned or roasted, the directional arrangement and the shape of the pores didn't be altered. However, the numbers of soil particles decreased, and the numbers of soil porosity increased, and the size of pores decreased. This study is of important significance to study ancient building materials and organizational system.

In this paper, the purest kind of  Gum Arabic, extracted from (Hashab) trees (in western Sudan ), is used in concrete mixes after crushing to be in a form of powder which was dissolved in water to get the liquid of this additive. In this study, Gum Arabic liquid was added to concrete mixes at ratios of 0.1%, 0.2%, 0.4%, 0.6%, 0.8%, 1.0 % and 1.2 % of cement content. Eleven concrete mixes were prepared: One as a control mix, seven with Gum Arabic liquid, and three with Gum Arabic liquid with modified water cement ratios added. This modification was done by reducing water cement ratios in concrete mixes to be 0.4 %, 0.6% and 0.8% of cement content. The study showed that the addition of Gum Arabic to the concrete mixes has a clear effect when equal to 0.4% of cement content. The compressive strength was measured at ages of 7, 21, and 28 days and it was found that it decreases slightly with increase in the proportion of Gum Arabic in concrete mixes. The concrete mixes prepared using modified gum Arabic in its liquid state by reducing (w/c) and adding gum Arabic as a percentage of cement content showed a clear and significant change in the properties of concrete. These ratios resulted in high compressive strength concrete with good workability. Keywords: Gum Arabic, Hashab, Sudan, compressive strength, workability

The article considers the multibiometric identification of a student to improve the quality and minimize errors in the process of his identification using voice and visual biometric features. Sound processing methods, models of neural networks and Gaussian mixtures for identifying a student by voice signs, and methods of visual identification of a person by video stream and photographs were studied. A software system has been developed for recognizing and indexing people on video while identifying a person by voice signs to use in the educational process to account for students attending remote classes. The system provides for the extraction of acoustic characteristics from a recording of a human language and the subsequent assignment of the obtained data to one of the specified classes (speakers). A multilayer neural network (MNN) was used as a classifier. The classifier was trained on a data set of 43832 audio files from 108 speakers. MHC on the test sample showed an accuracy of 91%. At the stage of processing the video stream frames, a face was detected in the frame, and the detected face was recognized. Face recognition in the system was based on the search for the most appropriate template of basic images stored in the database.


In some cases, manufacturers may have buy-to-fly ratios of less than 20%, prompting questions as to whether the most efficient manufacturing process is being selected in the design stage. There is a lack of objective pre-selection techniques and a need for a quick, broad and comparative study using key variables to assess potential processes. Proposed is a flexible down-select methodology that addresses this requirement while offering traceability and justification to the decision-maker. The need within the aerospace sector has been validated, while identifying scope for future development.


Using many-body theory we develop a set of formally exact kinetic equations for inhomogeneous condensate and one-body observables. The method is illutrated for phi^4 field theory in 1+1 dimensions. These equations, when computed with the help of time-dependent projection technique, lead to a systematic mean-field expansion. The lowest and the higher order terms correspond to, respectively, the gaussian approximation and the dynamical correlation effect.


Real time error checking is required in optical disk systems to improve data reliability and to increase data throughput to/from the computer. This paper describes a two-beam optical head which meets the requirement. The head is composed of two laser diodes (830 nm for write and servo operations, 780 nm for read operation), dichroic mirrors, and an achromatic objective lens. New optical servo technologies have been developed and incorporated in this optical head. One is a new focusing technology (called the Wax-wane method) which needs only two optical components. Another is a new tracking technology (called the ILT method) which enables a tracking range of ±400 μm.

Abstract This article explores the causes for and the contemporary ramifications of the realignment of the American South with the Republican Party. Using the American National Election Surveys (ANES) Time Series Cumulative Data File (1948–2016), the 2016 and 2020 Blair Center Polls, and the election tracking data compiled by Richard Berg-Andersson and Tony Roza at www.thegreenpapers.com, the author first explores the role that racial animus, anti-feminism, and religious fundamentalism played in white southern voters' emergence as the Republican Party base. Second, the author considers the structural advantages that this prominence in the GOP gives southern whites in the primary nomination process and to what degree these advantages benefitted Donald Trump in 2016. Finally, the author explores the influence of Racial Resentment, Modern Sexism, and Christian Fundamentalism on the 2016 Republican primary elections and the 2016 and 2020 General Elections.


We report the first case of human infection with the fungal plant pathogen Macrophomina phaseolina in a Sri Lankan-born Canadian man following a renal transplant in India. The patient subsequently succumbed to invasive infection with Scytalidium dimidiatum. Molecular sequence analysis confirmed the identification of both fungi and revealed that they are related species within the ascomycete family Botryosphaeriaceae. We review the rationale for the recent reclassification of S. dimidiatum as Neoscytalidium dimidiatum and of Nattrassia mangiferae (formerly considered a synanamorph of S. dimidiatum) as Neofusicoccum mangiferae. This and other recent cases illustrate the potential for plant pathogenic fungi to cause invasive human diseases which are refractory to antifungal therapy.
