T he DoD and almost all non-defense government agencies increasingly depend on large software-intensive systems. Unfortunately, with few exceptions, such large-system development projects are seriously troubled. While the programs may ultimately deliver workable systems, they are generally late, cost much more than planned, and some even fail completely. While guidelines such as CMMI provide useful guidance on what methods should be used, many studies have shown that seriously troubled large-scale development programs have one problem in common: They do not effectively follow the methods they currently know [1]. The two companies doing the work described in this article are the only suppliers the DoD has for a category of highly classified military equipment. These companies' development laboratories were in different cities and had very different engineering practices and support systems. This complicated the DoD's logistics and training systems, raised maintenance costs, and limited acquisition flexibility. The DoD had urged the companies to develop a common engineering design and support system, but the companies had resisted. Finally, the DoD issued a joint contract and directed the companies to develop a common system. To meet this directive on schedule and within prescribed costs, the senior executives of both companies knew they needed a joint development team that had a level of coordination and communication that they had not previously been able to achieve. Their joint team would have approximately 30 people from two competing organizations with several different disciplines and with different processes and practices. To build such a capability, they turned to the SEI for guidance. The project described in this article is the result. The SEI recommended that the two organizations use the TSP to guide them in jointly establishing the project's goals and objectives, agreeing on the project management strategy, and launching and managing the development work. To start TSP introduction , the SEI had both management teams come to Pittsburgh for a one-day executive seminar and a half-day planning session [2]. The seminar described how the TSP team-building process melds people from different specialties and organizations into high-performing development teams with common goals, practices, processes, and plans. TSP introduction also requires that team leaders take a leadership course and that team members take Personal Software Process SM (PSP SM) training [3]. All of the software engineers were trained in common classes where the team members met their counterparts from the other company and completed a series of 10 …

In this case pump gearing dynamic loads and gears teeth contact voltages increase assessment was conducted.


The relentless scaling of semiconductor technology has resulted in dramatic performance improvements of Integrated Circuits (ICs). However, traditional planar CMOS technology seems to have reached its limit. To continue with Moore's law, FinFET technology has shown to be a viable solution. Process variations are still relevant, however. Therefore, it is crucial to study their impact on circuit performance. This paper explores design choices for 20nm FinFET-based SRAM cells and analyzes the impact of process variations on the performance characteristics of the SRAM cell.

BACKGROUND
HIV epidemiology and intervention uptake among female sex workers (FSW) in sub-Saharan Africa remain poorly understood. Data from outreach programmes are a neglected resource.

METHODS
Analysis of data from FSW consultations with Zimbabwe's National Sex Work programme, 2009-14. At each visit, data were collected on socio-demographic characteristics, HIV testing history, HIV tests conducted by the programme and antiretroviral (ARV) history. Characteristics at first visit and longitudinal data on programme engagement, repeat HIV testing and HIV sero-conversion were analysed using a cohort approach.

RESULTS
Data were available for 13360 women, 31389 visits, 14579 reported HIV tests, 2750 tests undertaken by the programme and 2387 reported ARV treatment initiations. At first visit, 72% of FSW had tested for HIV; 50% of these reported being HIV-positive. Among HIV-positive women, 41% reported being on ARV. 56% of FSW attended the programme only once. FSW who had not previously had an HIV positive test had been tested within the last 6 months 27% of the time during follow up. After testing HIV-positive, women started on ARV at a rate of 23 / 100 person years of follow-up. Among those with two or more HIV tests, the HIV sero-conversion rate was 9.8 / 100 person years of follow-up (95% confidence interval 7.1-15.9).

CONCLUSIONS
Individual-level outreach programme data can be used to estimate HIV incidence and intervention uptake among FSW in Zimbabwe. Current data suggest very high HIV prevalence and incidence among this group and help identify areas for programme improvement. Further methodological validation is required.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial License 4.0 (CCBY-NC), where it is permissible to download, share, remix, transform, and buildup the work provided it is properly cited.

It has been shown that latency from a virtual reality (VR) user's motion to the display output leads to VR sickness, and in turn decreases the task performance. However, the effects of small delays under 13 ms have not been investigated as the VR systems have not been able to achieve these small latency values. The purpose of this study is to reveal the effects of small latencies on head mounted display users. The subjects in this study were asked to simply and stably stand on a force plate with one foot. The speed of body sway was measured with several lags, from 1 ms to 66 ms, using an Oculus Rift DK2. The results showed that the sway speed increased monotonically with increase in the latency values. The sense of balance is regarded as a relatively direct index of quality of a VR system, including the effects of lag.

In light of the unequal access to urban citizenship resulting from the household registration system (hukou), an increasing number of scholarly works have pointed out how a system of citizenship stratification has emerged in urbanising China. However, this stratification has seldom been analysed in terms of gender. Rural women, situated at the bottom of the hierarchy of differentiated citizenship, often suffer gender-based discrimination and tumble still further down the hierarchy. Specifically, women are vulnerable to economic and social dispossession in the process of the displacement of rural populations and renegotiation of land rights. Owing to the custom of patrilocal residence, women who have 'married out' (waijianü) have been excluded from rights, participation and entitlement to collective land property. By creating a class of rural female non-citizens, rural communities have deprived waijianü of opportunities to share land-related revenue realised in the process of urbanisation, further perpetuating male dominance just as local economies and society are in flux. Through a case study of these conflicts in Guangdong, this paper explores how women have challenged gendered citizenship in the process of urbanisation.


This paper discusses on an identification method of motor systems which have low resolution encoders. Since measurement data obtained from low resolution sensors have quantization errors, it is important for identification of a precise model to take the quantization error into account. A proposed method to overcome the problem is based on a numerical optimization. The effectiveness of the proposed method is verified by simulations and experiments, and the results are shown with some discussions.

In the quest to do away with every influence of colonialism including language imperialism, following the independence of several African countries, particularly in Sub-Saharan Africa, debates arose about the possibility of the adoption of Swahili as a common language for Africa since it was the most widely-spoken African language at the time. However, even though this discourse continued for some time, it did not go beyond this stage. In contemporary times, discourse on the Swahili language has emerged again, but this time it centres on the question of globalization of the Swahili language. This recent development therefore is the motivation for this paper. We seek to bring to light paradoxes that emanate from the debate and quest for the globalization of the Swahili language against the background of challenges that face the language at the national, regional and continental levels and to make submissions as to whether the quest for the globalization of the Swahili language is not just an illusion.


Recent years have witnessed rapid developments in the field of IC engines. Today both the manufacturers and the customers are looking for low polluting and better efficient engines. Basically, the in-cylinder gas motion affects the performance of the engine. Increase in combustion efficiency obviously results in fuel economy and low pollutant emissions. So, it is necessary to have a better control over in-cylinder gas motion. The main objective of this project is three dimensional flow calculations of the compression stroke of a four-valve direct-injection Diesel engine for different Piston configuration. A limited number of validation calculations of the Intake stroke and compression stroke were performed in order to explore the limits of Computational Fluid Dynamics representation of the in-cylinder flow. In the main study, the flow characteristics such as Swirl Ratio, Radial Velocity field and Tangential Velocity field inside the engine cylinder equipped with different piston configurations were analyzed in detail. The results confirmed that the piston geometry had little influence on the in-cylinder flow during the Intake stroke and the first part of Compression stroke. The bowl shape plays a significant role near TDC and in the early stage of the expansion stroke by controlling the turbulence velocity fields.


Many applications hinge on modelling phenomena observed or sampled through signal sequences or time realizations whose dynamics come from heterogeneous sources of uncertainty. This requirement applies to many scientific contexts, and results particularly challenging when a low signal-to-noise ratio exists, due to structural or experimental conditions, and the information core appears dispersed in a wide spectrum of frequency bands or resolution levels. The methodological and empirical work that is here presented aims to design ad hoc approximation instruments dealing with a particularly complex class of random processes that generates financial returns, or their aggregates in the form of index returns. It. is important to note that the underlying volatility function appears to be subject to the signature of noise and the masking effects of non-stationary superimposed dynamics, together with multi-scaling regimes. Due to the unobservability of the volatility function, its recovery represents an inverse problem that can be cast in a latent variable model designed to account for both switching multi-scaling regime and cascade system dynamics. Together with emphasizing the role of independent component analysis for achieving dimensionality reduction of the addressed inverse problem, we also stress the role of atomic functional dictionaries in improving the volatility feature detection power, and show the performance of greedy approximation algorithms in delivering sparse representations and coherent decompositions of the return sequences.


Nowadays, ultrasound examination is routinely utilized in the diagnosis of acute cholecystitis and its complications. Perforation of the gallbladder wall is usually suspected from indirect, non-specific sonographic findings, i.e. pericholecystic fluid collections, free peritoneal fluid, irregular gallbladder wall thickening, gallbladder distention, gallstones, coarse intracholecystic echogenic debris, and a complex mass in the gallbladder fossa (Forsberg et al, 1988; Chen et al, 1990). Sonographic visualization of the gallbladder perforation itself is rarely achieved (Chau et al, 1988; Takada et al, 1989; Chen et al, 1990). We report a case in which colour Doppler sonography allowed direct visualization of the biliary leakage across the gallbladder wall, thus providing the diagnosis. In addition, percutaneous catheter drainage of both the gallbladder and adjacent collection allowed the perforation to heal, hence avoiding surgery.


Abstract The basic idea that makes John Deely's Four ages of understanding an innovative one is that the notion of the sign is at the center of philosophical development from the start, and proves basic to a postmodern development of thought as well. A full awareness of this notion of sign can be traced way back to the beginning of the fifth century AD, in the works of Augustine, where the two different theories of signs present in the Greek period — the semantic theory of the linguistic sign (following an "equational" model) and the logical-epistemological theory of non-linguistic signs (following an "inferential" model) — are amalgamated. The aim of this paper is to show that Augustine makes a move that is both symmetrical with and a mirror image of what Saussure does: the latter unites the two theories and two classes of sign, setting up the linguistic sign as the guiding principle, while Augustine subsumes all types of sign within the class of non-linguistic signs. But it is the Augustine's move that opens, as Deely also says, a link with the postmodern era, proposing a semiotic model that is homogenous with that of Peirce.


Small heat shock proteins (sHSPs) act as molecular chaperones and are widely distributed in all kinds of organisms. Comparative analysis revealed that an orthologous shsp was present during insect evolution. Here, hsp21.8b, one insect orthologous shsp, had been identified in Tribolium castaneum. Quantitative real‐time PCR illustrated that Tchsp21.8b was expressed in all developmental stages, along with the lowest expression at early embryonic stage and relative high expression at other stages especially in late eggs and late pupae. In the adult period, Tchsp21.8b exhibited the highest expression level in central nervous system and followed in elytron, epidermis, ovary and fat body. Moreover, it was upregulated 3.39‐fold in response to enhanced heat stress (45°C) for 4 hr but not to cold stress (4°C) and was upregulated by 1.73‐ to 1.94‐fold under ultraviolet (UV) exposure during 4–6 hr. It was also downregulated by 20.8%–41.8% under starvation in 3 days and had a "down‐up‐down" trend under the pathogen stresses. Larval RNA interference of Tchsp21.8b caused 40.6% insects mortality and reduced the oviposition amount by 66.0% and only 21.0% of the ds‐Tchsp21.8b eggs could hatch into larvae. These results suggested that as an orthologous shsp, Tchsp21.8b not only plays important roles in the growth, development and fecundity of T. castaneum but with the competence to resist the environment stresses, although the response is relatively weak compared to other hsps. Results from this study also uncovered the functions of the orthologous shsp in the development and anti‐stresses ability of T. castanuem. It provided more scientific evidence for revealing the physiological mechanisms of shsps of the insects and enhanced the capabilities to control different pests.

This article also offered some useful suggestions which help to preserve the sources of reptile and amphibia.


In this paper, we propose a method to measure surface compliance distribution of a curved surface object from a remote position for haptic information transmission. We achieve remote measurement by utilizing an ultrasound phased array. The measured surface compliance is estimated by information of distance and gradient dependencies of the acoustic radiation pressure. Finally, the measurement of a real object which has distributed surface compliance and reflectivity is performed.


Trichoderma viride ITCC‐1433 secretes a cellulase complex that is rich in β‐glucosidase and therefore well suited for the saccharification of cellulosic materials. The cellulase was investigated with respect to optimum conditions of reaction and enzyme stability. Avicelase, CMCase, and β‐glucosidase differed considerably in their physicochemical properties. At temperatures above 50°C, β‐glucosidase is not very stable. Therefore, as a compromise the conditions of hydrolysis were chosen to be 50°C and pH 4.5. With the crude culture filtrate of T. viride ITCC‐1433 a nearly pure glucose solution of 4% is reached from a 10% cellulose suspension. Wood pulp and newsprint are hydrolyzed to a much smaller extent. With an enzyme concentrate up to 8% glucose accumulated in the reaction fluid within 48 hr. At this time the glucose‐cellobiose ratio was 75:1. Glucose was demonstrated to be the most potent inhibitor of total hydrolysis. The addition of glucose to the enzyme‐substrate solution at zero time completely stopped its own formation and cellobiose and reducing groups (oligosaccharides) accumulated. By removing glucose through an ultrafilter device about 90% saccharification of cellulose to glucose was achieved in 48 hr without any accumulation of cellobiose.


Abstract 'Great houses' built by the Ancestral Puebloans (Anasazi) (900–1200AD) still contain thousands of pieces of wood used as beams, secondary roof supports and lintels. The wood is an integral part of the surviving Chacoan architecture and has served as a valuable resource for determining the exact age of the structures and for obtaining information about raw material production, procurement and harvesting methods. An assessment of wood deterioration at the great houses in Aztec Ruins National Monument and Pueblo Bonito, Pueblo del Arroyo and Chetro Ked located in Chaco Culture National Historic Park in New Mexico have revealed that both microbial and non-biological deterioration was taking place. The major type of decay found throughout the structures was caused by soft-rot fungi. Cavity formation in secondary walls of conifer woods and an erosion of cell walls in aspen woods was prevalent. A brown-rot type of wood degradation was also found, primarily associated with areas of subterranean termite damage. Another form of deterioration present in some of the woods was a chemical de fibration of wood. This corrosive attack, caused by high concentrations of salts, destroyed the middle lamella between cells, resulting in a stringy mass of loosely attached fibres. Reburial of great house structures as an effective conservation strategy will require an environment that is not conducive to decay, since active wood-destroying fungi are present in the prehistoric woods. If moisture and other conditions suitable for decay exist, the wood will be destroyed and this important historical resource lost.


On 2015 January 6–7, an interplanetary coronal mass ejection (ICME) was observed at L1. This event, which can be associated with a weak and slow coronal mass ejection, allows us to discuss the differences between the boundaries of the magnetic cloud and the compositional boundaries. A fast stream from a solar coronal hole surrounding this ICME offers a unique opportunity to check the boundaries' process definition and to explain differences between them. Using Wind and ACE data, we perform a complementary analysis involving compositional, magnetic, and kinematic observations providing relevant information regarding the evolution of the ICME as travelling away from the Sun. We propose erosion, at least at the front boundary of the ICME, as the main reason for the difference between the boundaries, and compositional signatures as the most precise diagnostic tool for the boundaries of ICMEs.


The course construction and teaching mode in the integration project of virtuality and reality for die mould specialty were proposed aiming at the characteristics of vocational school students and situation of die mould specialty. The resource construction and effects based on the background of course construction were discussed.


The liquefaction of fat in adipose tissue for potential medical applications was achieved by direct irradiation using an atmospheric-pressure plasma source and a catheter-type apparatus. When fat was irradiated with plasma generated from a catheter tip, it was liquefied through ozonolysis, although little production and diffusion of ozone originating from the collision/ionization of gas molecules was observed in preliminary experiments. Furthermore, surface damage to fat cells, such as thermal carbonization or electric shock injuries, was not observed.


Objective: To evaluate the antimicrobial activity of 2% chlorhexidine gel, copaiba oil, propolis extract and calcium hydroxide associated to propylene glycol on Enterococcus faecalis. Methods: Fifty single-rooted human teeth were prepared until K-file #50 and distributed into groups according to the intracanal substances. The positive control group was only propylene glycol. Subsequently, 100µL of microorganism broth was inoculated into the roots, except in the negative control group. Then the roots were placed in individual test tubes immersed in BHI and put into incubator at 37° C for 48 hours. After the turbidity of the medium, the roots were irrigated with sodium thiosulfate, filled with one of the test substances and immersed in BHI for 7 days at 37° C. Thereafter, the drugs were removed from the roots with help of K-files and abundant irrigation with sodium thiosulfate. The roots were immersed in BHI for 24 hours. After this, the tubes were analyzed by single trained examiner to the categorization of the culture medium turbidity. Conclusion: According to this methodology, it was possible to conclude that none substance was effective against Enterocossus faecalis.


On 24 September 2004, the plaintiff (BBB) raised an action before the Turin District Court against the two defendants with the request to invalidate a number of trade marks containing the term ''Bavaria'' based on and the German-Italian Treaty of 1963. On 30 November 2006, the Turin District Court granted the request, whereupon Bavaria appealed. The Turin Court of Appeal referred the case to the ECJ for an interpretation of Regulation 1347/2001 (case C-343/2007). Regulation 1347/2001 established the Community registration of the term ''Bayerisches Bier'' as a protected geographical indication for beer according to the Regulation 2081/92. The CJEU established that there were no reasons to question the validity of such registration. Yet, in view of the fact that ''Bavaria'' was a trade mark previously registered in good faith, there was no reason to find such trade mark invalid under Regulation 2081/92, either. In a further decision on the issue of Bavaria, this time

A hierarchical approach for the determination of a manpower and machinery configuration for a naval tender machine shop is presented. The application of numerically controlled machine technology is stressed. A mixed integer programming model is developed to support aggregate decisions regarding machinery and manpower allocations. The job shop performance under the suggested aggregate characteristics is tested by a detailed simulation model. An iterative procedure links both models to ensure satisfactory overall performance. Typical naval tender machine shop workload is used in the model implementation. Thesis Supervisor: Arnoldo C.

Novel urchin-like boehmite(AlOOH) superstructures consisting of nanorods were successfully synthe-sized by a template-free hydrothermal synthetic route in an ethanol-water solution.The crystal structures and the morphologies of boehmites were characterized by X-ray diffraction(XRD),scanning electron microscope(SEM),transmission electron microscope(TEM) and selected area electron diffraction(SAED).The effects of the precur-sors,the volume ratio of EtOH/H2O and reaction temperatures on the morphologies were also discussed.It is shown that the 3D urchin-like boehmite of uniform morphology and good dispersibility is prepared using AlCl3.6H2O as the precursor at 200℃ with the volume ratio(EtOH/H2O) of 1:2.The diameter of the urchin-like boehmite is 6-10μm,which is consisted of nanorods with the diameter of 60-80nm.The SAED pattern reveals the polycrystal-line nature of the urchin-like boehmite.The oriented attachment mechanism plays a key role on the formation of urchin-like boehmite superstructures.


Knowledge discovery and analysis has become one of the major needs of the current information rich world. Effective information identification and prediction requires effective models. Several machine learning models are available for prediction. This paper concentrates on classification, a supervised machine learning model. An effective classifier can enable effective predictions. However, not all input data are perfect to enable highly accurate classification. Several factors such as data imbalance, noise and borderline entries affect the classifiers. This paper proposes a Lean SVM based Ensemble Model (LSEM) that enables effective classification of data without the need for pre-processing. A heterogeneous ensemble is created using Random Forest and One-Class SVM. The requirement of partial training data for SVM makes the model lean, enabling faster training. Experiment is conducted on data with varied imbalance levels and it is identified that the proposed LSEM operates better than state-of-the-art models and ensembles and hence enabling better predictions.


Rice black-streaked dwarf virus (RBSDV) was reported to occur on maize plants in Gochang-gun of Jeonllabuk-do region in 2011. The symptoms typically include stunted and deformed leaves. Virus infected plants usually produce poor or no head. RT-PCR analysis of genomic dsRNA extracted from the plant confirmed the infection. Specific primers for full length genome of segments 8 and 10 were used for RNA amplification. Full-length genomes of S8 and S10 were cloned and sequenced. Sequence analysis revealed that the S8 and S10 sequences of the maize isolate were same with rice isolate in size, 1,936 nt and 1,801 nt, respectively. In comparison with rice RBSDV, S8 and S10 showed 94.9-99.6% and 94.1-98.4% sequence identity, respectively. Phylogenetic analysis showed that RBSDV S8 and S10 of maize plants are categorized into the same group as RBSDV of rice plant.


The regulation of a restorative material in the international and the American markets is discussed. The 510(k) process of approval by the Food and Drug Administration allows marketing of safe, effective, and improved materials in the shortest time at the lowest cost. The American Dental Association contributes to developing consensus performance standards in the United States. Acceptance of International Standards Organization standards is discussed.


Beneficial invertebrate activity was assessed in 2005 and 2006 in three organic and one conventional vegetable field using pitfall and pan traps. Data was generated from a total of 208 trapping sites in cauliflower, leek, cabbage, purple sprouting broccoli and calabrese crops and 80 sites in planted field margins. More activity of epigeal invertebrates was found in Brassica fields compared with leek fields and there was more in organic than conventional Brassica fields. Activity of useful invertebrate groups in the field margins decreased with vegetation development and there appears to be a need for management of margins in order to optimise activity of the most appropriate beneficial groups for the crop planted.

Local photovoltaic (PV) systems are playing a considerable role globally as a power resource and constituent element of the smart grid. Nevertheless, PVs may cause significant problems to the electric grid. This is due to the high variability of the PV power that is instigated by intermittent environmental conditions. Accurate prediction of PV power is very important to operate power grids containing high penetration of PVs. Most prior approaches have focused on forecasting the collective quantity of solar power generation at national or regional scale and disregarded the local PVs that are installed mainly for local electric supply. This paper devises an effective input dataset identification methodology (IDIM) to find the most significant and non-repetitive input variables for accurate prediction of the power production of local PVs. In the devised methodology, the Binary Genetic Algorithm (BGA) is used for the input variable identification and Support Vector Regression (SVR) is employed for evaluating the fitness of the input datasets. The devised methodology is implemented and validated based on actual local PVs (building rooftop PVs) located in the Otaniemi area of Espoo, Finland. The results are compared with those obtained by conventional counterparts and manifest outperformed performances.


Object tracking and monitoring is used for detection purpose. This research is found since last two decades. However, the scope is there for further improvement. Cur-rent deep neural network model is found suitable in this area exclusively. We examine the problem of vehicle discov-ery by the deep learning method. In addition, we have shown that the use of deep features extracted from a pre-formed network produces a more efficient and ac-curate means of monitoring. Fast Recurrent CNN, the use of these systems becomes bottleneck process with relevance to CNN's operation. Fast R-CNN solves this downside by applying the projected mechanism to use the region and then CNN. An RPN is a fully convex network that predicts object boundaries and object scores at each location simultaneous-ly.


The invention discloses an anti-aging PPH (polypropylene homopolymer) material. The anti-aging PPH material comprises an antioxidant, color master and a PPH raw material, wherein the mass ratio of the antioxidant to the color master to the PPH raw material is 1:(3-3.5):(300-350), the antioxidant is the mixture of an antioxidant 1010 and an antioxidant 168, and the mass ratio of the antioxidant 1010 to the antioxidant 168 in the antioxidant is (3-5):1. According to the anti-aging PPH material, the antioxidant is added to the material, so that molecules of the PPH material are not prone to decomposition under ultraviolet light at a high temperature, the antioxidant ability is greatly improved, and the requirement that manufactured products can be used for more than 10 years is met.


Olivine LiFePO4/C composite cathode materials have been synthesized by a solid state method in an inert atmosphere.The physical parameters,crystal structure and electrochemical performance were characterized by specific surface area measurements,X-ray diffraction,scanning electron microscopy and electrochemica1 performance testing.The effects of using different combinations of carbon sources—sucrose,acetylene black and citric acid—on the performance of the as-synthesized cathode materials were investigated and the origins of the observed differences were analyzed.The results demonstrated that when a composite carbon source(sucrose,acetylene black and citric acid) was used,the tap density and particle size(D50) of the materials were comparable to the corresponding values obtained with the same amount of a single carbon precursor,but the specific surface area was reduced.The initia1 discharge capacity of the material derived from the composite carbon source was higher—154 mAh/g at room temperature and a discharge rate of 0.1C,and 142 mAh/g at discharge rate of 1C—but the values of initial impedance and polarization were also increased.

10 MeV electrons delivered by the 15 MeV linear electron accelerator of the University of Ghent are used to irradiate a tantalum/graphite bremsstrahlung source. Since earlier work showed that the theory given by Monte Carlo simulations of the source using the codes EPCOT and EGS4 overpredict the spectrum's intensity at low energy, a new direct measurement of the bremsstrahlung source was conducted with a germanium detector at different angles. Another germanium detector was used which improved the quality of the gamma-ray spectrum and similar but better experimental set-up geometries were constructed. In order to make a clear comparison between simulations and direct measurements, the Monte Carlo calculations included not only precise simulations of the sources but also of the germanium detector response. All these improvements were done to understand the disagreement between the Monte Carlo simulations and the first measurement.


In this paper we propose an autonomous docking and human-robot collaboration system for an automated guided vehicle (AGV). The AGV can not only navigate and dock autonomously, but also collaborate with the human by recognizing human in the environment. A human motion detection system is developed for the proposed human-robot collaboration design. A deep learning network is adopted to detect and recognize humans in the environment. By knowing of human motion, the AGV adjusts the automatic docking behavior in a collaborative manner. Practical experimental results demonstrate that human workers can co-exist with an AGV in an unstructured environment for autonomous docking tasks.


The Paul Scherrer Institut (PSI) is still the only centre in thc world capable of applying proton radiotherapy with a spot-scanning technique by means of a dedicated beam delivery system (gantry). The RT scientifie eommunity, which essentially groups radiooncologists and physicists speeialized in this partieular seience braneh, has noted the advantages that such a technique could bring for the treatmcnt of ecrtain tumors and new facilities dedicated to this particular type oftherapy are currently under construction or in planning in sevcral countries in the world. The 3D superposition of modulated proton pencil beams characterizes the spot-seanning technique and is an excellent tool to provide intensity modulated proton radiotherapy (IMPT), which is particularly indicated, or evcn compulsory, when critical organs (e.g. the spinal cord) must bc spared from radiation. In this case the dose homogeneity required for the target volume is obtained by thc superposition of inhomogcneous dose fields applied under different anglcs. Thc number of patients that received IMPT at PSI is constantly inercasing sinee 2002 and in 2004 more than 20% of the patients have been treated totally or partially with such a therapy. In order to ensure an optimal therapeutic course quality, it is neeessary, among others, to develop tools that are able to measure and verify the complex dose distribution before it is applied to the patient. Such tools should be able to verify dose plans in 3D providing infonnation concerning the behavior of the dose both laterally and in depth preferably with one single measurement. With thc presently used dosimetry system, this is possible only by repeating the measurernent several times with different setups. Hut then both the data taking and data analysis are extremc1y time consuming, limiting thus the application. Thcrcfore, in this work a dosimetry system, unique of its kind, was developed for 3D dose verification. The system consists in 400 dose detectors distributed in a Polyethylene phantom. Each detector consists in a small cylindrieal scintillating volume coupled to an optical fibre with 2 rnm diameter. The optical fibre transports the signal from the seintillator to a CCD camera for signal reading. The scintillating volume has a dimension of only 0.005 crrr'. The system was developed in a way to allow modifying the distribution of the sensors within the phantom as much as one likes. The minimum possible distance between two neighbor scintillators is 8 rnm and the total covered volume is 15.6 cm x 13.2 cm x 8 cm. The system was tested choosing a deteetor configuration that allows to verify simultaneously profiles lateral and in depth when thc

In recent years, radar, especially frequency-modulated continuous wave (FMCW) radar, has been extensively used in non-contact vital signs (NCVS) research. However, current research does not work when multiple human targets are close to each other, especially when adjacent human targets lie in the same resolution cell. In this paper, a novel method based on complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN)–independent component analysis (ICA) was proposed to obtain the vital-sign information (including respiratory rate and heart rate) of adjacent human targets by using a single FMCW radar. Firstly, the data observed at a single angle were decomposed by the CEEMDAN separation algorithm to construct virtual multi-angle observations. It can effectively transform the undetermined blind source separation (UBSS) problem into an overdetermined blind source separation (BSS) problem. Thus, a BSS algorithm based on FastICA can be used to reconstruct each person's vital-sign signal and then calculate their respiratory rate/heart rate. To validate the effectiveness of the proposed method, experiments based on the measured data were conducted and the results show that the proposed method can obtain multi-target vital-sign information even when they are in the same resolution cell.


ABSTRACT The present study develops a SAR-based shoreline monitoring system which consists of: (i) selection of SAR scenes suitable for shoreline detection; (ii) extraction of shoreline from the selected scenes; and (iii) estimation of the shoreline at arbitrary water level. The first model focused on ALOS-2 SAR scenes and determined fitting formulae for estimation of the backscattering coefficients at a sea and a beach surfaces. To quantify the suitability of scenes for shoreline detection, a parameter, P, was newly introduced. The value of P represents a probability at which a backscattering coefficient at a beach becomes higher than the one at a sea and it was confirmed that P reasonably indicates suitability of scenes for shoreline detection. A shoreline extraction technique was then developed based on the edge detection technique. Bilateral filter was applied to reduce the speckle noise of SAR images and wavelet transform was applied to detect the edge location. Validity of the proposed technique was confirmed through application of the present technique to Shimizu and Shonan coasts. Finally, a simple polynomial function was introduced to represent the shoreline location at arbitrary water level. Applicability of the proposed technique was also tested and validated against the detailed data obtained by image analysis.


This paper deals with measurements of and an integral model for a buoyant axisymmetric jet in a very small co-flow. The integral model is based on the insights gained from the measurements presented here and other recent experiments, which suggest that the turbulent flow is simply advected and the entrainment is that normal for a jet or plume in a still ambient fluid. General equations for the turbulent flow trajectories are also developed. The predictions of the theory are verilied for the no cross-flow case and the cases where the jet or plume is ejected vertically or horizontally into a very small cross-flow. The results of experiments in which a buoyant jet is released in the same direction as the horizontal ambient flow, show that outside the turbulent region the entrainment velocities can be represented with uniform flow and the appropriate sink. Direct measurement of the strength of the sink allows the transition from weakly- to strongly-advected behaviour to be determined. The departure of the trajectory measurements from the theory also provides information about the transition. The transition location is then compared with recent measurements in which the jets and plumes are ejected vertically into a very small cross-flow.


Management of the aging bridge infrastructure is demanding an increased understanding of all aspects of the performance of existing bridges. Loading models are an important consideration in the risk assessment of a structure. Quantifying the actual in-service dynamic response of a structure can make a significant difference in terms of keeping a bridge in service. Code-recommended allowances for dynamic effects range between 20 and 40 percent for major elements. Higher values are sometimes recommended for local effects. It is well understood that parameters including the unevenness of the road profile, the potential of frequency matching between heavy vehicles and the bridge, vehicle speed, and heavy-vehicle load levels all contribute to the dynamic response of a bridge to a single-vehicle event. Multiple vehicles increase the complexity even further. Recent new editions of bridge codes around the world tend to have diversified the methods and allowances for dynamic effects. These methods are compared, and then they are compared with a database of experimental responses measured in a range of structures in Australia and New Zealand during recent years. The results clearly illustrate the importance of each of the above parameters and that very large dynamic responses can be achieved, particularly in short-span structures.

Abstract.
 Eight bat species were known and documented from the California Channel Islands when J.C. Von Bloeker (1967) presented at the First California Islands Symposium in 1965. Additional bat surveys by P.E. Brown (1980) in the 1970s resulted in "Distribution of bats of the California Channel Islands," which was presented at the second symposium in 1978. Methods of detecting and identifying bats have changed over the past century. Museum collection methods using shotguns have been replaced by mist-netting and recording of echolocation calls. Currently, capture or acoustic records have identified 14 bat species (56% of the 25 species known to occur in California) on 6 of the 8 California Channel Islands, with occasional sightings of flying bats on Anacapa and San Miguel Islands. Bats now compose 78% of the native mammals on the islands (Collins 2012). Acoustic recording equipment has become smaller and easier to use in the field, and recorded echolocation signals are now recognized as valid "vouchers" if the species emits calls that are separable from others. For example, echolocation signals have identified western red bat (Lasiurus blossevillii), hoary bat (Lasiurus cinereus), western yellow bat (Lasiurus xanthinus), and Mexican free-tailed bat (Tadarida brasiliensis) from San Nicolas Island, and western mastiff bat (Eumops perotis) and canyon bat (Parastrellus hesperus) from Santa Cruz Island. Acoustic data have identified 3 new species for the California Channel Islands, as well as several new records on individual islands. As acoustic monitoring and other techniques are used more extensively, the number of species documented will increase and the proportions that are resident, vagrant, or transient on each island can be better resolved.


The polarization correlations in the elastic scattering of spin-polarized electrons from unpolarized nuclei are compared with those which occur in the process of bremsstrahlung. The polarization correlations in these two reaction channels tend to agree for very heavy nuclei in the limit of ultrahigh collision energies.


Drug development can be approached from numerous angles, i.e. bio-activity, receptor binding, structural analysis combining small molecules with proteins, fragment-based drug design, functionalization of model pharmaceuticals, etc. Our interest is in the coordination of biomolecules and bifunctional chelators to technetium(I) and rhenium(I) for use as diagnostic or therapeutic radiopharmaceutical agents. The synthesis of radiopharmaceuticals can be accomplished by a good understanding of the transition metal chemistry of the specific reagents involved, but the kinetic effects caused by the bound molecules on the metal centre is critical for understanding reactivity, stability and structure. This study focuses on the kinetic and crystallographic properties of the fac-[M(L,L')(CO)3(S)] (M= Re, Tc) model radiopharmaceutical complexes utilising the {2+1} approach. The significant labilisation caused by the coordinated bidentate ligands and the isostructural behaviour of the crystallised complexes will be highlighted.


To assess species affiliation of bone fragments by examining histological characters using a sample of two male skeletons(skulls and long bones only) aged 20 years and 30 years.The human sample was collected from forensic autopsies.Bone was cut into 2mm histological section plates,which were then observed at 10×20 power with an Olympus,HB-20 microscope.Different parts of the human skeleton showed a variety of bone histological characters and different parts of the same bone(for example,the upper and lower sections of a long bone) showed various microscopic structures.The outer and inner circumferential lamellae, interstitial lamellae,osteons,and bone lacuna were observed on different parts of the bone.Histological characters of compact bone and spongy bone were described,and with this qualitative data entered into the computer.Photomicrographs were also taken.This study has demonstrated a new method for bone fragment identification in forensic anthropology,which is also useful to studies in anthropology and archaeology.


In statistical modeling, an overparameterized model leads to poor generalization on unseen data points. This issue requires a model selection technique that appropriately chooses the form, the parameters of the proposed model and the independent variables retained for the modeling. Model selection is particularly important for linear and nonlinear statistical models, which can be easily overfitted. Recently, support vector machines (SVMs), also known as kernel-based methods, have drawn much attention as the next generation of nonlinear modeling techniques. The model selection issues for SVMs include the selection of the kernel, the corresponding parameters and the optimal subset of independent variables. In the current literature, k-fold crossvalidation is the widely utilized model selection method for SVMs by the machine learning researchers. However, cross-validation is computationally intensive since one has to fit the model k times. This dissertation introduces the use of a model selection criterion based on information complexity (ICOMP) measure for kernel-based regression analysis and its applications. ICOMP penalizes both the lack-of-fit and the complexity of the model to choose the optimal model with good generalization properties. ICOMP provides a simple index for each model and does not require any validation data. It is computationally efficient and it has been successfully applied to various linear model selection problems. In this dissertation, we introduce ICOMP to the nonlinear kernel-based modeling areas. Specifically, this dissertation proposes ICOMP and its various forms in the area of kernel ridge regression; kernel partial least squares regression; kernel principal component analysis; kernel principal component v regression; relevance vector regression; relevance vector logistic regression and classification problems. The model selection tasks achieved by our proposed criterion include choosing the form of the kernel function, the parameters of the kernel function, the ridge parameter, the number of latent variables, the number of principal components and the optimal subset of input variables in a simultaneous fashion for intelligent data mining. The performance of the proposed model selection method is tested on simulation benchmark data sets as well as real data sets. The predictive performance of the proposed model selection criteria are comparable to and even better than cross-validation, which is too costly to compute and not efficient. This dissertation combines the Genetic Algorithm with ICOMP in variable subsetting, which significantly decreases the computational time as compared to the exhaustive search of all possible subsets. GA procedure is shown to be robust and performs well in our repeated simulation examples. Therefore, this dissertation provides researchers an alternative computationally efficient model selection approach for data analysis using kernel methods.


In this study,a recombinant expression vector of human interleukin-24(hIL-24) gene,named pET-28a(+)-hIL24,was constructed by gene cloning.The recombinant protein hIL-24 was expressed in E.coil and analyzed by SDS-PAGE and Western blotting.The proper inducing conditions of its expression were explored.The results showed that the recombinant protein was about 25 ku and mainly existed in the precipitation after sonication.Western blotting proved that the recombinant protein IL-24 was recognized by mouse anti-human IL-24.SDS-PAGE analysis indicated that the best expression condition was 0.5 mmol·L-1 IPTG for 8 h at 37 ℃.The successful expression of hIL-24 in the prokaryotic expression system is helpful for the further study of its biological function.


Prefabrication as a sustainable construction method has become a trend for use in house construction. However, the construction of rural houses in China still mainly adopts on-site construction, which also raises wasteful resources and environmental problems. Previous studies lack an evaluation system for the implementation potential of prefabricated rural housing in counties, and thus cannot provide references for the government to formulate implementation strategies. This study uses PEST analysis to establish an evaluation index system for the implementation potential of prefabricated rural housing and then evaluates 32 counties in Chongqing with urbanization rates below 90% based on the entropy weighted TOPSIS model. The results show that the weight values of the four evaluation subsystems of political, economic, social, and technological are 0.4516, 0.3152, 0.0684, and 0.1648, respectively; the nearness degrees of Dianjiang, Yubei, Jiangjin, and Rongchang are 0.5475, 0.4439, 0.4312, and 0.4103, respectively, ranking in the top four in Chongqing. The results indicate that the potential of implementing prefabricated rural housing in Chongqing is closely related to policy orientation and construction industrialization; Dianjiang, Yubei, Jiangjin, and Rongchang have the relative advantage of implementing prefabricated rural housing. Finally, this paper proposes political, economic, social, and technological suggestions for the implementation of prefabricated rural housing in Chongqing.


A symmetric and conserved energy-momentum tensor for a scalar field in a moving medium is derived using the Gordon metric. When applied to an electromagnetic field, the method gives a similar result. This approach thus points a way out of the old Abraham-Minkowski controversy about the correct energy-momentum tensors for the electromagnetic field in a material medium. The new tensor describes the properties of the field alone while the Abraham tensor contains information about the field coupled to the medium.


Low light images suffer from a low dynamic range and severe noise due to low signal-to-noise ratio (SNR). In this paper, we propose joint contrast enhancement and noise reduction of low light images via just-noticeable-difference (JND) transform. We adopt the JND transform to achieve both contrast enhancement and noise reduction based on human visual perception. First, we generate a JND map based on an the human visual system (HVS) response model from foreground and background luminance, called JND transform. Second, for base image, we perform perceptual contrast enhancement based on luminance adaptation to effectively allocate a dynamic range to each gray level while preventing under enhancement (tone distortion) and over-enhancement. Third, we refine the JND map using Weber's law, luminance adaptation and visual masking. Weber's law enhances the JND map based on the luminance variation after contrast enhancement. Luminance adaptation suppresses noise for smooth regions, while visual masking enforces detail enhancement for textural regions. Fourth, we perform inverse JND transform to generate the enhanced luma channel from the JND map and base image. Finally, we conduct chroma denoising by transferring texture information of the enhanced luma channel to the chroma channels with guided filtering. Experimental results show that the proposed method achieves both contrast enhancement and noise reduction for low light images as well as outperforms state-of-the-art methods in terms of quantitative measurements.

Abstract:From 1932 to 1973, Chicago women who wanted to avoid the high costs and impersonal treatment of the city's maternity wards had another option: they could choose to give birth at home, attended by obstetricians and nurses of the Chicago Maternity Center (CMC). As the rest of the nation moved towards the hospital as the normalized place of delivery, low-income white women and women of color in Chicago continued to assert not only their preference for home birth but also their demand for affordable, dignified, and family-centered care. When the CMC was threatened with closure, women from diverse backgrounds joined together to save this alternative maternity option. This article explores how these Chicago mothers resisted hospitalization and asserted their right to choose home birth years before the women's health movement offered a similar critique.


This article analyses the sexual innuendos, the 'irreverent' postures and the sex talk which marked a number of ethnographic encounters with women in north India. While these encounters discursively harassed the anthropologist's interpretive categories, Indian women's 'excess of agency' established a joking intimacy with her. Where encounters radically subverted aspects of the representational history of women across colonial and postcolonial India, their novel representational possibilities opened up new ones for those women writing on them. Finally, encounters signalled the urgent need for research in the largely unknown terrain of heterosexuality in India, and this research's potential to rethink the semantics of gender.


The increase in the ratio of new energy reduces the inertia of microgrids and poses a threat to the stable operation of microgrids. To ensure the stable operation of microgrids, the virtual synchronous generator control technology is used for new energy units, and the virtual inertia constant needs to be reasonably designed. In this paper, the system kinetic energy combined with the output ratio of the new energy unit is taken as the index of system inertia evaluation. Then, the frequency response characteristics are analyzed, and an optimization model of inertia design considering frequency stability constraints is constructed and solved. The simulation experiments verify that the proposed method can improve the frequency stability after a power fluctuation.

In this article, we describe a method for filtering the textual indexing of images which cover general subjects. To this purpose, we build first visual clusters for each keyword of the lexicon by means of an ascending hierarchical clustering of visual vector. Then, we test the validity of the association keywords/visual clusters using a test base and we measure the performance of the classification with the "normalized score". Lastly, we use visual clusters to filter the textual indexing and to obtain an improvement of the indexing going up to 40% depending of the visual consistency of the word.

SUMMARY This paper presents a multi-dimensional particle tracking technique for applying the Lagrangian-Eulerian finite element method to solve transport equations in transient-state simulations. In the LagrangianEulerian approach, the advection term is handled in the Lagrangian step so that the associated numerical errors can be considerably reduced. It is important to have an adequate particle tracking technique for computing advection accurately in the Lagrangian step. The particle tracking technique presented here is designed to trace fictitious particles in the real-world flow field where the flow velocity is either measured or computed at a limited number of locations. The technique, named 'in-element' particle tracking, traces fictitious particles on an element-by-element basis. Given a velocity field, a fictitious particle is traced one element by one element until either a boundary is encountered or the available time is completely consumed. For the tracking within an element, the element is divided into a desired number of subelements with the interpolated velocity computed at all nodes of the subelements. A fictitious particle, thus, is traced one subelement by one subelement within the element. The desired number of subelements can be determined based on the complexity of the flow field being considered. The more complicated the flow field is, the more subelements are needed to achieve accurate particle tracking results. A single-velocity approach can be used to efficiently perform particle tracking in a smooth flow field, while an average-velocity approach can be employed to increase the tracking accuracy for more complex flow fields.


Water and nutrient use efficiency are primary requirements for optimum and sustained citrus productivity. The interactive effect of irrigation and fertigation levels on fruit quality parameters of 10-year-old sweet orange (Citrus sinensis L. Osbeck) cv. Phule Mosambi was studied in factorial randomized block design with nine treatment combinations and control with surface irrigation and band placement of conventional fertilizers. The interaction effects in the treatment T1 (I1F1) i.e. irrigation level I1-100% etc. through drip along with fertigation level F1-100% RD through WSF recorded significantly the maximum juice, optimum TSS, higher ascorbic acid, reducing sugars, non-reducing sugars, total sugars and A grade fruit yield. There was also a significant influence of T1 (I1F1) on per cent A grade fruit yield.


The ideal protein concept for pigs has allowed reducing levels of crude protein in the diet, since synthetic amino acids are included because the branched chain amino acids may be limiting. In order to determine the digestible isoleucine requirement for gilts from 15 to 30 kg, a performance assay was accomplished, using 40 crossbreed gilts of high genetic potential, averaging 15.00 ± 0.52 kg of body weight, alloted in a randomized blocks design, consisting of five treatments (0.45, 0.52, 0.59, 0.66, 0.73% of digestible isoleucine), four replicates and two animals per experimental unit.  Performance traits were determined and at the end of the experiment one animal per experimental unit was slaughtered to determine carcass composition and organs weight. Levels from 0.45 to 0.73% of digestible isoleucine did not affect the carcass traits and organs weight of gilts from 15 to 30 kg. A quadratic effect (P<0.05) of digestible isoleucine levels on isoleucine efficiency for weight gain was observed, that increased up to 0.506% digestible isoleucine, which ratio of digestible isoleucine: lysine was 0.51.


Canada is one of the world's highest per capita spenders on healthcare. Yet provinces consistently boast lackluster performance on important measures of their population's health and access to healthcare (Davis et al. 2014; Doty et al. 2020). Spurred by public reporting, unease among governments about how to fix the problem and the lack of obvious solutions, much discussion focuses on improving the "value" of spending on healthcare (Papanicolas et al. 2018; Shrank et al. 2019).


This paper examines the relationship of the trickster character to the maintenance of Great Lakes Native American cultural identity by using interviews and literary analysis. The interviews gathered statements from participants about their personal experiences with narrative, and the social context of narrative, within their tribes. The literary analysis examines three stories in the Manabozho cycle: "The theft of fire," "Manabozho and wolf," and "The flood." The themese in these stories fulfill all four of William Bascom's four functions folklore. The hypothesis that narrative is a necessary factor of cultural maintenance has been supported by both the interviews and the literary analysis.

Due to its large piezoelectric and spontaneous polarization coefficients combined with the possibility of being grown lattice-matched with GaN, wide bandgap ScAlN is becoming a promising material in III-nitride semiconductor technology. In this work, and for the first time, ScAlN growth has been performed by molecular beam epitaxy with ammonia source as nitrogen precursor. High electron mobility transistor heterostructures with a 26 nm thick Sc0.15Al0.85N barrier have been grown on GaN-on-sapphire substrates. The effect of growth temperature, ranging between 620 and 800 °C, was carefully investigated. A smooth surface morphology with a mean roughness below 0.5 nm is obtained whatever the temperature while for 670 °C the (0002) and (10[Formula: see text]3) x-ray diffraction rocking curves show minimum full-width at half-maximum of 620 and 720 arc sec, respectively. Furthermore, two-dimensional electron gases with a high density of 3-3.5 × 1013/cm2 were evidenced in the heterostructures grown below 720 °C.

A sliding mode control (SMC) strategy is presented for a 2 degrees of freedom (DOF) helicopter system, which achieves asymptotic attitude regulation to desired set points as well as trajectory tracking. A rigorous Lyapunov-based analysis is provided to prove convergence to the desired set points. To overcome the practical limitations of velocity measurements, a sliding mode observer is designed to estimate the angular velocities. The convergence of the estimated velocities to the actual velocities is proven via a rigorous Lyapunov-based analysis and illustrated through computer simulations. In addition, computer simulations are presented, to demonstrate the effectiveness of the control law when applied to the complete nonlinear system dynamics. Finally, the control strategy is experimentally tested on the Quanser 2-DOF AERO helicopter. The results of the observer-based SMC strategy are compared to a conventional PID-controller.


The current paper presents an upgrade of a pre-installed hydraulic system for the operation of a pallet handling robot for a freight delivery vehicle known as FURBOT (freight urban robotic vehicle). The automated forklift installed on FURBOT for loading/unloading of cargo is powered with the help of hydraulics. The previous hydraulic system worked via a classical approach with a fixed displacement pump and a bypass valve, making it work on full power when in use. An alternative design was proposed, simulated and installed on FURBOT; it uses a fixed displacement pump and changes the rotation speed in real time using a pressure sensor. Novelty was attained with the use of gear pumps for said scenario. A control algorithm is implemented in the processing unit for controlling the speed of the motor driving the pump. The main advantage of this approach is better use of energy for the vehicle's battery. The aim of this research is to control both the speed and maximum force exerted by the actuators with the help of a single sensor and an inexpensive pump.

A preliminary study of the creep of polycrystalline pollucite at 1400{degrees}C - 1500{degrees}C was done for sintered and hot-pressed samples. Although the pollucite samples were either poorly consolidated or had large amounts of mullite and silica from cesia loss during processing, the maximum flow stresses were still comparable to those for polycrystalline yttrium-aluminum garnet (YAG) and mullite. However, unlike mullite and YAG, these flow stresses were typically reached only after at least 5% strain. Samples that did not support large strains failed in compression at under 35 MPa. The incongruent vaporization of cesia was also measured, and the reactivity of pollucite with various materials was noted. Processing methods for pollucite are discussed.


2-Amino-4-(4-tert-butylphenylamino)-6-{4-[(4-pyridyl)ethynyl]phenylamino}-1,3,5-triazine was synthesised and mixed with dibutylbarbituric acid in CDCl3 to study rosette formation. The formation of a double decker rosette aggregate was studied by complexation of the pyridyl groups to a zinc containing porphyrin dimer.


OBJECTIVE
To discuss the relations of dental fluorosis and the social economic status in fluorosis-stricken villages where drying the corn by burning coal was prevail.

METHODS
A total of 6 fluorosis-endemic villages and one non-endemic village were involved in the study. The general fluorine intake and the concentrations of fluorine in corn, in the pupils' were tested. Dental fluorosis among the pupils was also examen. A individual interview or household questionnaire survey was conducted to probe the economic condition and staple food structure in 600 adults.

RESULTS
The fluorosis prevalence was lower in the villages of transportation convenience, higher income, less coal-dried corn intake. There was a declining trend of dental fluorosis in the corresponding age groups (r: 0.912, 0.916; P < 0.05); There was no significant changes in age-specified dental fluorosis in the low income villages. The correlation (r) of corn fluorine concentration and student's age-specified dental fluorosis prevalence and disparity was 0.755 - 0.980 (P < 0.05) and 0.302 - 0.811; The urine fluorine concentrations were 0.811 and 0.915 (P < 0.05). It was assumed that there was a negative correlation between family cash income and the dental fluorosis.

CONCLUSIONS
The corn fluorine concentration is closely related to age-specified dental fluorosis. With the economic improvement, taking less coal-burned corn is the one of major factors in reducing the of dental fluorosis in these areas.

Cocoa drinks are greatly demanded by consumers, considering that Indonesia has a relatively high temperature. The purpose of this study was to examine mathematically, the characteristics of instantized cocoa powder produced using continuous-type steam jet agglomerator with 8 hours drying duration. The variables used in this study were fat content (11, 27%, and a mixture of both) and maltodextrin content (25, 30, 35, and 40%). The results of this study indicated that fat, maltodextrin and their interactions affected the characteristics of instantized cocoa powder. It can be seen from several characteristics that instantized cocoa powder had higher solubility values (40-65%) and lower dispersibility values (3-5%) than those of reference sample, made without "hot" steaming process.


Even though antibiotic eluting bone cements are successfully used in orthopedic practice, adding chemotherapy drugs to bone cement pose a different set of problems. This is mainly due to the toxicity concerns associated with the use of chemotherapy agents. To avoid local or systemic toxicity, the drug elution profile of a particular bone cement/drug concentration need to be determined. The drug elution profile depends on many factors including initial drug concentration, mixing conditions, surface area of the bone cement implant, etc. In this study, the effect of initial methotrexate amount on bone cement elution was measured.


The quality of care in the NHS in England is being sustained despite the drive for efficiency savings, the Nuffield Trust and the Health Foundation have found in a joint programme of research. But despite this reassuring conclusion they say that more could be done to reduce the number of emergency admissions to hospital, especially of older people.

The findings are the first to come from a collaboration between the two organisations, which plan over the next five years to keep a scorecard of quality in the NHS, assessing whether it is improving, stable, or declining by evaluating almost 150 quality indicators that cover the whole spectrum of health and social care. The programme, QualityWatch, will examine access, safety, effectiveness, …

An important natural hazard affecting to the road networks and to the traffic in semiarid areas is caused by the flood waters in road stream crossings. The paper has as principal aim to propose a methodology for evaluating the hazard of road-ephemeral channel crossings, from exposition levels and hydrological, hydraulic and morphological criteria. This approach has


Customarily the Structure Factor S(Q) of liquids is determined experimentally by the costly and cumbersome X-ray and neutron scattering methods. Previously we have shown that [1] internal pressure could be used effectively to arrive at the structure factor of argon using the total correlation function (TCF) proposed by Phukan and Bhuyan [2]. In the present paper we propose a simple method of calculating the S(Q) of the liquids argon, krypton, sodium, potassium, rubidium, indium and CCl 4 , involving a two step procedure: the ranges of the repulsive and attractive force components are first characterised using experimentally determined Internal Pressure π i data using two different TCFs. These values are in turn tested by calculating S(Q). The agreement between the experimental and calculated positions of the principal maxima (PPM) of the S(Q) vs Q curves is quite convincing. In an actual scattering (neutron or X-ray) experiment, Q is the momentum change of the incident beams. In our work, Q continues to have the same meaning in the 'hypothetical' experiment.


Tianjin has acquired enormous achievements since the reform, however,a series of problems emerged during the rapid economic growth. This paper evaluates the sustainable development capacity of Tianjin from 1990 to 2000 by the principal component analysis, and accordingly analyzes the factors which limit the sustainable development of Tianjin, such as inconsistency of economic structure, lack of water and imbalance between economy and environment. Then the paper gives some suggestions for the sustainable develepment in Tianjin.


We studied an Nd:KGd(WO& laser (A = 1.067 pm, flash-lamp pumping) with KTiOP04 (KTP) serving as both an intracavity electrooptic Q-switch and frequency doubler. An altemating electric field was applied along the z-axis of KTP. The considerable increase in the efficiency of the frequency doubling was achieved for the type-I1 interaction. The pulse duration of green radiation was 200 ns, and the pulse energy was 1 mJ. The solid-state Nd-doped lasers with the frequency doubling began to replace gasion lasers in.commercia1 and laboratory applications about 12-15 years ago. The trend is still quickening due to the progress in the diode-pumped systems and nonlinear frequencydoubling crystals, such as p-BaB204, LiB305, LiNb03 and KTP. Several techniques have been used to achieve efficient conversion' of basic radiation (A = 1.06 pm) into its second harmonic 0.53 pm, The frequency doubling via nonlinear processes is the most complicated for lowpower Nd-doped lasers. This is due to the. fact that one needs pumping power of the order of 1 kW inside the crystal to obtain reasonable conversion efficiency. For low-power lasers this is achieved through intracavity doubling, Q-switched operation, or by using highsensivity nonlinear crystals, such as periodically poled LiNb03, KTP. The pulsed laser operation through active or passive Q-switching provides high conversion efficiency. Traditionally, the laser systems with @switched operation have two separate optical elements: active or passive Q-switch and nonlinear doubler. In this work we offer a new approach to frequency doubling that could help to increase doubling efficiency. We propose, particularly, to combine the @switching and frequency-conversion functions in a single-element nonlinear 2rystaI. In our opinion, KTP has been used successfidly as an electrooptical Q-switchdoubler for few reasons. First, KTP is highly nonlinear, has high optical damage threshold, wide acceptance angle and thermally stable phase-matching properties. Secondly, its large linear electrooptical coefficients and low permittivity make KTP attractive for Q-switching application. And finally, the most effective frequency doubling at the wavelength of 1.06 pm is achieved for the type-I1 interaction and beam propagation in the xy-plane. KTP is a biaxial orthorhombic crystal (point group nzm2). Its refractive indices allow second harmonic generation (SHG) processes of both (I and 11) types. The conditions for phase matching and effective nonlinear coefficient deff in biaxial crystals, in particular KTP, have been derived'). Some data exist on the propagation angle for type-I1 phase matching at wavelength of 1.064 pm in KTP. Non-critical phase matching at this wavelength occurs for 8 = 90" and p = 22+26O (here 6 is the angle between the beam propagation direction and z-axis, p is the propagation angle in the xy-plane relative to the x-axis.). The type-I1 SHG process is characterized by interaction between two pump waves of different polarizations. Thus this interaction is nondegenarate, and the conditions for phase matching are as follows:


The Indian Ocean has gradually emerged as a significant region in terms of the economic and geopolitical patterns of the world powers. In the contemporary power struggles, it has become a most important contesting ground for global dominance. This research analyses the Geo strategic significance of the Indian Ocean and the interests of regional and great powers in it. The study is particularly focusing on two sub-regions of the Indian Ocean (IO) (Arabian Gulf and South Asia) and is mainly probing the strategic competition between New Delhi and Islamabad in these areas. And the structural enforcement these South Asian countries are receiving from Washington and Beijing. Active engagements of great powers in the said regions also highlight the global dynamic of strategic competition IO. The research concludes that different strategies adopted by regional and global powers to increase their sphere of influence in IOR are consequently enhancing strategic dilemma and initiating arms race between regional powers and that any mishandling can easily ends up in a war, which may not be an ordinary one because all the states focused in the current study are nuclear capable.


Arabic belongs to the Semitic group of languages. Ibn Qahtan is popularly known as the father of this language. Between the ninth and twelfth centuries more works, philosophical, medical, historical, religious, astronomical and geographical were produced through the medium of Arabic than through any other tongue. The non-Arab community began to depend on import of petrol from the Arab world. This dependence increased greatly during the first half of the twentieth century. This concern created strong connections between non–Arabs and Arabs. One of the results of these connections was the interest of non-Arabs in Arabic. Today, it is one of the official languages of the UNO and is spoken by a large group of masses in Asia and Africa. Would you believe India has more than 50,000 people whose mother tongue is Arabic? According to 2001 Census data on linguistic groups, India had 51,728 people whose mother tongue is Arabic. Arabic is the mother tongue in some 20 nations stretching from the Atlantic coast of North Africa in the west to the Sultanate of Oman in the East, and from Syria in the north to Sudan in the south. Arabic plays a vital role in the commercial and cultural fields.

Implementation : Developing strong mentoring relationships has always been an important component for success. And, it has been the keystone on which (Association for Women in Science) AWIS has built its programs over the past three decades. This is an interactive workshop to include a powerpoint presentation with questions asked of the participants throughout the presentation. Individuals will work in small groups or share their responses in a large-group setting. The  workshop has been presented numerous times in the past two years, most  recently at Iowa State University, the University of California-Davis, and Middle Tennessee State University, and has been well received by past  participants. Description : In 1990 AWIS created the AWIS Mentoring Project which attracted over 3,000  participants. As a result, a paperback book titled A Hand Up: Women  Mentoring Women in Science was written for women scientists. In  2009 AWIS published its second mentoring book, authored by Dr. Donna Dean, titled Getting the Most out of Your Mentoring Relationships , which  focuses on providing an overview on being mentored in the diverse fields encompassed by STEM. Before beginning the AWIS mentoring program, 80% of the participants recognized that they faced barriers in combining the roles of being a woman and a scientist. Three years later, 62% of these participants stated that the AWIS Mentoring Program helped them identify and overcome barriers to their success. Today, over 75% of AWIS members participate in mentoring programs. The focus of the Mentoring program is to provide individuals in STEM with  an appreciation for how important mentoring is as well as the tools and techniques that they will need to find mentors and best utilize them. The topic of how to be a good mentor will also be discussed as well as what to expect from mentees. The goals of the program will help individuals to: 1. Examine the difference between mentoring, coaching, and sponsoring. 2. Recognize how to identify your mentoring needs. 3. Learn how to identify and approach a potential mentor. 4. Understand how to use mentors to help achieve your goals and advance your career. 5. Identify the do's and don'ts involved in being a good mentee or mentor. 6. Appreciate how mentoring impacts work-life satisfaction. Learning objectives of the program : 1. Understand the importance of mentoring and how it can advance your career. 2. Understand how serving as a mentor can help you to "pay it back". 3. Develop an action plan to identify your mentoring needs. 4. Identify potential mentors and initiate a mentoring relationship. 5. Appreciate the do's and don'ts involved in being a mentor or a mentee.


The Internal Revenue Service ("IRS") has sought ways to increase casinos' tax liabilities by changing their use of an accounting method that allows the casinos to exclude from income large amounts of cash they have on hand at the end of the year. These large amounts of cash on hand result from the casinos' exchange of chips for cash. Casinos generally exclude from income the cash they receive from these transactions by classifying them as an incurrence of a liability as opposed to an advancement of a receipt. However, the IRS argues that the casinos' classification of these transactions as liabilities is inappropriate and at least a portion of the cash casinos receive in this exchange must be included in gross income. Casinos use the accrual method to account for income from gaming activities. Under the accrual method of accounting, each casino calculates their income from gaming activities as the amount the casino has won on the patrons' wagering transactions less any amount the casino has lost from similar transactions. Missing from this equation is the cash the casino receives in exchange for the chips the patrons use to gamble. Instead of counting this cash received as income, casinos record these transactions on their books as outstanding liabilities. This approach allows the casinos to exclude the exchange of cash for chips when the patron receives the chips and when the patron


This article examines the letters of Ausonius - those correctly so called - with a view to elucidating their individual aims, the general conventions of Ausonius' correspondence, and his relations with such men as Symmachus, Petronius Probus and Paulinus of Nola and less well-known friends. Attention is paid to the interpretation of various obscure passages and to the artistry, structure and wit of the poems.

Due to costly efforts during data acquisition and model training, Deep Neural Networks (DNNs) belong to the intellectual property of the model creator. Hence, unauthorized use, theft, or modification may lead to legal repercussions. Existing DNN watermarking methods for ownership proof are often non-intuitive, embed human-invisible marks, require trust in algorithmic assessment that lacks human-understandable attributes, and rely on rigid thresholds, making it susceptible to failure in cases of partial watermark erasure. This paper introduces ClearMark, the first DNN watermarking method designed for intuitive human assessment. ClearMark embeds visible watermarks, enabling human decision-making without rigid value thresholds while allowing technology-assisted evaluations. ClearMark defines a transposed model architecture allowing to use of the model in a backward fashion to interwove the watermark with the main task within all model parameters. Compared to existing watermarking methods, ClearMark produces visual watermarks that are easy for humans to understand without requiring complex verification algorithms or strict thresholds. The watermark is embedded within all model parameters and entangled with the main task, exhibiting superior robustness. It shows an 8,544-bit watermark capacity comparable to the strongest existing work. Crucially, ClearMark's effectiveness is model and dataset-agnostic, and resilient against adversarial model manipulations, as demonstrated in a comprehensive study performed with four datasets and seven architectures.


We propose to perform feature similarity learning (FSL) module on raw point clouds. Many works aggregate local information based on Euclidean space neighbors. However, several nonlocal point pairings share features that are very similar. Based on this, we divide the FSL module into two sub-modules: 1) initial local feature aggregation (ILFA) module based on Euclidean space and 2) nonlocal feature aggregation (NLFA) module based on feature space. Specifically, ILFA module utilizes the Fast Point Feature Histogram (FPFH) descriptor to aggregate local neighboring information. Then, the NLFA module searches the feature space calculated by the ILFA module firstly for comparable features. By encoding feature similarity, the NLFA module learns and aggregates nonlocal information. Our method can more effectively capture local and global geometric features by combining the two submodules. We apply the FSL module to the DGCNN frame network and achieve state of the arts performance on benchmarks such as ModelN et40, ShapeN et, and S3DIS.


For the purpose of teaching we regard tuberculosis in a similar way to syphilis, in so far that we make the difference between the primary, secondary, and tertiary stages. The primary stage includes the primary lesion of the corresponding lymphatic glands, and this, in the vast majority of infections on the Continent, means a primary focus in the lungs and an infection of the bronchial glands. The secondary stage comprises the transportation of bacilli and formation of tubercles in all parts of the body?bones, joints, subcutaneous tissue, the skin, brain, and so on. By the tertiary stage we mean the tuberculosis of the lungs ?phthisis. This stage occurs rarely in children, and the disposition of the lungs for cavity formation seems to have some connection with sexual development as it begins during puberty ?in girls some years earlier than in boys. The prognosis of tuberculosis depends partly on the situation and the extent of the foci, partly on the age of the patient, and partly on his state of nutrition.
