Abstract : Military conflicts have been changing from the traditional large force engagements, where the winners are decided by who has the most men left standing, to unconventional asymmetric warfare where a military force can win every battle but still lose the war. Warfare is evolving, partly due to the technology that is being leveraged by the military. Advanced targeting capabilities and precision guided weapons, like the Joint Direct Attack Munitions (JDAM), give commanders in the field the capability to strike a target at any time and virtually ensure its destruction or neutralization. This capability has led to a new way of thinking and targeting called Effects Based Operations (EBO). EBO focuses soley on achieving operational objectives rather than inflicting kinetic damage. This relatively new way of thinking is conducive to the consideration of socio-cultural factors, but unfortunately our operational level planners have not been taught how to do this. Our operations and planning have traditionally been approached from a Western, Anglo-American perspective. Planners don't have a clear understanding of how tactical level actions will be perceived by the local population, and how those perceptions could negatively impact the attainment of the overall military objectives. Plans that are developed without the consideration of socio-cultural differences will more often than not lead to additional friction, impacting the overall timeline for accomplishing the mission. This is all too common and can be witnessed by watching the nightly news. To support the warfighter and improve upon the military's ability to efficiently achieve their objectives, the Air Force Research Laboratory and Securboration have developed a cultural awareness training tool for the Air Operations Center (AOC).


Background Diabetic peripheral neuropathy is one of the most common and disabling complication of diabetes mellitus. Aim The aim of this study was to investigate the effect of pulsed electromagnetic field (PEMF) on diabetic peripheral neuropathy. Settings and design A total of 30 patients with diabetic neuropathy from both sexes were selected from the Outpatient Clinic of Diabetes Mellitus, Faculty of Medicine, Cairo University, with age ranging from 40 to 50 years. They were divided into two equal groups: PEMF group (group A) and control group (group B). Materials and methods Group A received PEMF with frequency of 50 Hz and intensity of 20 G in addition to traditional physical therapy program. Group B received traditional physical therapy program only. The treatment program was conducted three times per week for 4 weeks. Measurements of pain intensity by visual analog scale and peroneal nerve conduction velocity by computerized electromyography device were done before and after treatment. Results Results revealed that there was a significant reduction of pain intensity and significant improvement of peroneal nerve conduction velocity (m/s) in both groups (P<0.05), with slightly in favor of group A. Conclusion It could be concluded that PEMF combined with traditional physical therapy program has a positive effect on diabetic neuropathy symptoms.

This study aimed to find out the planning, challenges, rational vision and mission offers, and the implementation of the 2020 regional election in Tidore during the new normal period. The applied method in this study was descriptive-qualitative using an interactive model approach. The results of this study can be stated with the following conclusions. (1) In the context of planning and preparation for the 2020 regional election in Tidore, it is necessary to pay attention to the successes and possible failures of the 2019 general election by setting a transparent and integrated planning and preparation concept for all parties who will determine the success of this regional election; (2) The general challenge faced by the government and the people of Tidore, especially for the Regional General Election Commission (in Indonesian: Komisi Pemilihan Umum Daerah (KPUD)) in organizing the 2020 regional elections, is how to carry out the regional elections democratically based on the direct, general, free, secret, honest, and fair principles as a process of maturing public political behavior; (3) The special challenge faced by each pair of candidates is to offer a concept of a realistic, actual, accurate, and precise development vision and mission according to the development, needs, potentials, and problems of the people of Tidore.


ABSTRACT The paper focuses on the peculiar dynamic behaviour of the recently developed 8 mm2 TO-220-packaged, high-voltage, double-interdigitated (or rwo interdigi-tation levels—TIL) GTO thyristor. This novel power device was rated under both slightly and heavily inductive resistive loads, i.e. close to the real conditions encountered in practical power circuits employing GTO thyristors. Emphasis is laid on the ability of TIL GTOs to switch safely, with minimum power losses, a certain amount of anode current under high-voltage conditions and high commutation frequencies. The merits of TIL GTO thyristors are analysed in terms of their reliability and switching efficiency, which include the total power losses (conduction and switching losses), turn-on and turn-off gains and the switching speed. It is shown that thanks to their built-in self-protective features, these novel GTOs possess an enhanced current-handling capability at commutation frequencies up to 50kHz under extremely tough load conditions. The m...


This paper considers the future of contract law in Europe. With the recent publication of the European Commission's Communication on European Contract Law, the debate on the feasibility and contents of a unified European contract law will probably broaden from a merely academic debate to a political one. The main tenet of this paper is that a proper political perspective on the future of European contract law cannot consist of a 'generalizing approach' such as the formulation and enactment of principles of European contract law. The future of contract law in Europe lies in recognizing tendencies of divergence in the law of contract, rather than in enacting general abstractions. This plea for a fragmented European contract law is preceded by a sketch of the historical development toward a general law of contract.


Multicore architectures have been used to enhance computing capabilities, but the energy consumption is still an important concern. Embedded application domains usually require less accurate, but always in-time, results. Imprecise computation (IC) can be used to divide a task into a mandatory subtask providing a baseline quality of service (QoS) and an optional subtask that further increases the baseline QoS. This paper aims at maximizing the system QoS by solving task mapping and dynamic voltage and frequency scaling for dependent IC-tasks under real-time and energy constraints. Compared with the existing approaches, we consider the joint-design problem, where task-to-processor allocation, frequency-to-task assignment, task scheduling, and task adjustment are optimized simultaneously. The joint-design problem is formulated as an  $\mathcal {NP}$ -hard mixed-integer non-linear programming, and it is safely transformed to a mixed-integer linear programming (MILP) without performance degradation. Two methods (basic and accelerated version) are proposed to find the optimal solution to an MILP problem. They are based on problem decomposition and provide a controllable way to trade off the quality of the solution and the computational complexity. The optimality of the proposed methods is proved rigorously, and the experimental results show reduced computation time (23.7% in average) compared with the existing optimal methods.


Background. p53 mutations are the most frequently observed tumor‐related genetic changes. Mutational analysis concerns mostly carcinomas and is not comprehensive for soft tissue sarcomas. Among soft tissue sarcomas, malignant fibrous histiocytoma (MFH) and liposarcoma represent the most frequent tumor types. Most of the few identified mutations for soft tissue sarcomas are localized in the core domain of p53. A correlation between p53 positive immunoreactivity, missense mutations, and a poor prognosis is generally assumed. However, the character of p53 mutations and their functional importance for the clinical process is still unknown.


Presented are the results of researches on selection and compositional structure of most efficient demulsifying solution made on the basis of industrially manufactured agents and lab chemical samples. The results of pilot tests of the chosen demulsifyer on the AOOT LUKoil-Langepasneftegas facilities are reviewed.


The power density of power systems is often dominated by the package of power electronic components. Using smaller packages results in lower cost but also in poorer thermal performance and higher heat sinking effort. However, if one considers general side conditions, it is possible to reach the same thermal performance even with a smaller package. This paper discusses two methods of defining the thermal junction-ambient resistance and the commonly used wave solder assembly technology. It also describes the test setup and the results of tests done with various packages and transistors


A plurality of aggregate photoconductive particles having a predominant particle size of less than about 1.0 micron are disclosed. Such particles are useful in heterogeneous photoconductive compositions, electrophotographic elements and electrophotographic imaging processes.

Many studies of soil and water conservation in third world situations show that among the farmers' incentives the commercial view on his management is important and that at the same time intangible considerations are playing an important role. In developing countries the partial acceptance or complete refusal of advice for soil and water conservation is often attributed to the backwardness and stubbornness of the land users. This analysis is deficient. Each farmer is constantly involved in active search for possible improvements in agricultural practices, albeit in a variable, individual way (Brouwers 1993, p. 121). Less attention has focussed on the attitude of the expert who gives the advice. His limited understanding of the non-material motivations of the land users has contributed its share to inappropriate advice. Such motivations often play an important role in village life.


A n g w E f t t c t s 2 5 h c a Abstract—Glucose-6-phosphate dehydrogenase (G6PD) eficiency affecting erythrocytes is the most common enzyopathy in humans. It requires caution with the intake of xidizing substances (e.g., medications and foods) because f the threat of hemolysis. Less recognized is the threat of a eficiency in G6PD that alters neutrophil function, which an compromise the killing of microbes by the oxidative urst mechanism. This results from a secondary alteration n the NADPH oxidase pathway. Methicillin-resistant taphylococcus aureus (MRSA) infection, which is usually bserved after exposure in the hospital setting, is becoming ncreasingly common in a community setting. Here we show he risk of MRSA and G6PD deficiency and discuss the itfalls of G6PD deficiency. © 2009 Elsevier Inc.


Nitrogen dioxide (NO2) is one of the widely detected gases in various applications including the detection of environmental pollution where NO2 is one of the major components, as well as, in industrial, medical, and occupational safety measurements. Nitrogen dioxide is also widely used to develop the complete reaction mechanism of the metal-oxide-based gas-sensitive layer due to its simplicity, which is based on the adsorption models. In this paper, the MoO3-based gas sensor that operates in the microwave frequency range was developed. The enhanced detection was observed due to the utilization of the eight-port reflectometer measurement method.


The problem of heat and mass transfer accompanying the absorption of water vapor into LiBr-H₂O liquid solution flowing over the outside of the horizontal cylinder was theoretically studied to understand the absorption process occuring in the absorber of the absorption heat pump. Numerical results are presented for various quantities of interest relating to temperature, concentration, heat flux and mass flux. Also, the effects of mass flowrate, initial average velocity, and the radius of the cylinder were investigated.


Biometric authentication has been incredibly useful in services such as access control to authenticate individuals based on their biometric traits. Unlike password or identity documents, biometric traits, such as fingerprint, iris and behavioral characteristic are physically linked to an individual that cannot be easily manipulated. The traditional biometric authentication model uses a server-centric model, where a service provider maintains the biometric database and is totally responsible for the security of templates. The end-users have to fully trust the provider in storing, processing and managing their private templates. As a result the end-user templates could be compromised by outside attackers or even the service provider itself. As a result we propose a usercentric biometric authentication scheme that enables end users to encrypt their own templates with our proposed lightweight encryption scheme at the time of authentication.


BACKGROUND: Highly polymorphic autosomal short‐tandem‐repeat (STR) analysis can be useful in most kinship testing. Y‐chromosome‐specific STRs, in contrast, have been increasingly applied for the verification of equivocal paternal genetic transmissions.


Fatigue is a complex physiological phenomena which is a kind of human body's natural response and self-regulation for protection. Detection of fatigue is becoming indispensable for its positive significance in scientific physical training. Recently, many researchers from both speech signal area and machine learning area have already shown that automatically fatigue detection from speech can carry out, but there is still plenty of room for the improvement of the recognition accuracy. The key to raise the accuracy in voice-based fatigue detection is precise phonetic identification and alignment. Therefore, this paper proposes a method for detecting sports fatigue which is based on feature extraction and machine learning system - support vector machine (SVM). In order to establish a comprehensive identification system, speech samples are trained as speech sources at different times. Experimental results state the feasibility and effectiveness of this method we put forward. What's more, Receiver Operating Characteristic Curves (ROC Curves) are used to double check the results, so that the application of sports fatigue detection is ensured.


An {\em $(\alpha,\beta)$-spanner} of a graph G is a subgraph H such that $\mathit{dist}_H(u,w)\le \alpha\cdot \mathit{dist}t_G(u,w)+\beta$ for every pair of vertices u,w, where distG'(u,w) denotes the distance between two vertices u and v in G'. It is known that every graph G has a polynomially constructible $(2\kappa-1,0)$-spanner (also known as multiplicative $(2\kappa-1)$-spanner) of size $O(n^{1+1/\kappa})$ for every integer $\kappa\ge 1$, and a polynomially constructible (1,2)-spanner (also known as additive 2-spanner) of size ${\tilde O}(n^{3/2})$. This paper explores hybrid spanner constructions (involving both multiplicative and additive factors) for general graphs and shows that the multiplicative factor can be made arbitrarily close to 1 while keeping the spanner size arbitrarily close to O(n), at the cost of allowing the additive term to be a sufficiently large constant. More formally, we show that for any constant $\epsilon, \lambda > 0$ there exists a constant $\beta = \beta(\epsilon, \lambda)$ such that for every $n$-vertex graph G there is an efficiently constructible $(1+ \epsilon, \beta)$-spanner of size $O(n^{1 + \lambda})$.


Non Point Sources (NPS) of phosphorus (P) are a leading contributor to freshwater eutrophication, which is a persistent and acute global water quality problem. Many of the strategies used to minimize such pollution are not always effective, since their design is often based on processes involved in soil P dynamics that are yet not well enough understood. Vegetative Filter Strips (VFSs) are one commonly employed practice. However, they are prone to saturation, and P release is a common phenomenon in flooded soils. Some of the mechanisms proposed to explain P fluxes under flooding conditions include P release from soil microbial biomass due to the decay induced by osmotic shock and shifts in the microbial community; the potential role of facultative bacteria capable of luxury aerobic P uptake and anaerobic P release, i.e. Polyphosphate Accumulating Organisms (PAOs); and the release of P bound to iron (Fe) oxides as the result of Fe reduction. In this research, the significance of such mechanisms of P release in flooded soils from a VFS receiving silage leachate were investigated by maintaining undisturbed soil cores under flooding and draining cycles with acetate and glucose as carbon (C) sources, followed by an aerobic P enrichment period in order to promote intracellular polyphosphate (polyP) storage by PAOs. P release during flooding was dominated by organic forms, probably derived from the decay of soil microbial biomass due to an initial osmotic shock and a subsequent shift in the


In this work we have extended and implemented an ontology based approach for email classification based on user characteristics proposed by Kim et al.(2007). The approach focuses on finding relationships between user interests and their responses to emails. Rules and Ontology are created using the data and metadata of user characteristics, their preferences and responses to emails. Rules and ontology are then used to predict the response of a user to a new email. In Kim et al. (2007) approach, labels to emails were provided manually by a human expert. We have endeavored to remove the human intervention by developing an Automated Email Categorizer to provide label to an email based on its contents. We have also proposed a new term weighing method for emails to incorporate prominence of subject terms. Finally, we have integrated and tested the Ontology Based Classifier in conjunction with Email Categorizer where the former effectively uses the label provided by latter to classify an email based on user preferences.


Bilateral lagophthalmos secondary to facial nerve is extremely uncommon. Further, the aetiology in most of these cases is of central origin unlike the peripheral involvement in leprosy. A patient of lepromatous leprosy (LL) may be euthyroid or hypothyroid on account of leprous involvement of the thyroid gland. A case of LL with bilateral lagophthalmos and hyperthyroidism is reported.


KNIGHT, J. and BURNINGHAM, H., 2007. Coastal morphodynamics and prehistoric human occupation, County Donegal, NW Ireland. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 104 - 108. Gold Coast, Australia, ISSN 0749.0208The complex interrelationship between coastal morphodynamics and prehistoric human occupation of coastal landscapes is explored from two important sand dune sites in County Donegal, NW Ireland. These sites, which are Atlantic-facing and which are morphologically responsive to decadal to millennial-scale climate changes, have a long record of human occupation as evidenced by the presence of Neolithic to Medieval artifacts, occupation horizons, soils and shell middens. Relationships between sand dune development and human activity are identified at these sites through description of archaeological horizons exposed in section, and surrounding dune sands. Results show the role of human-induced land surface changes that impact on succeeding dune sedimentation patterns. Feedback between the physical processes of dune accumulation and human activity within sand dune systems - not previously discussed in the literature - are key to understanding human-landscape relationships over decadal to millennial time scales and can be usefully applied to such relationships in other sensitive geomorphic settings.


Background: Role of additional axillary treatment (AxT) (axillary lymph node dissection (ALND) or axillary radiotherapy (ART)) in women with ≤2 macrometastases and undergoing systemic therapy remains unclear. Z11 included both micro and macrometastases (around 40% micrometastases) and showed that ALND may be omitted in women with ≤2 positive nodes undergoing breast conserving surgery (BCS) and receiving whole breast RT. Paradoxically, NCIC MA20, demonstrated improved DFS following the addition of regional RT. 51.8% (949/1832) had 1 or 2 positive nodes. 98.9% (1812/1832) had T1/T2 tumours. A post-Z11 survey shows that most US radiation oncologists treat the undissected axilla in women with macrometastases with ART rather than omitting AxT. Therefore, a confirmatory study is needed to clarify the role of additional AxT in women with ≤2 macrometastases undergoing BCS and other subgroups that were not included in Z11 e.g. mastectomy, microscopic extranodal invasion and sentinel node biopsy (SNB) before neoadjuvant chemotherapy. Methods: Primary objective is to assess whether for women with ≤2 macrometastases at SNB, systemic therapy alone is non-inferior to systemic therapy plus AxT in terms of axillary recurrence at 5 years. Secondary objectives are arm morbidity assessed by LBCQ and QuickDASH questionnaires; QoL assessed by FACT-B+4 questionnaire; anxiety assessed by STAI; loco-regional recurrence; distant metastasis; time to axillary recurrence; axillary recurrence-free survival; DFS; OS; contralateral breast cancer; non-breast malignancy; and economic evaluation. Eligibility criteria include: ≥18 y, uni or multifocal invasive cancer, T1/T2, 1 or 2 macrometastases, with or without extranodal invasion. Target sample size is 1900 with a projected drop-out and non-compliance with treatment allocation rate of 10%. Primary analysis will be per protocol. The following pre-specified subgroup analyses shall be performed: number of macrometastases (1, 2), age ( Citation Format: Goyal A, Mann B, Thompson AM.

How do Millennial and Gen-Z young adults decide between competing social media when choosing where to post? Previous research argues that decisions can be modeled based on these users' Goals, and the Affordances, Features1, and Social Norms of those media. To evaluate this model, 19 participants were given different self-presentation scenarios and asked to choose between Twitter, Snapchat, Instagram, and TikTok. Participants also constructed a flowchart to represent their mental model of factors influencing their choices. Data suggest revisions to the model; rather than reflecting Affordances and Features, we found that Social Norms and Goals primarily drove participants' choices. Participants choose media based on a direct match between Goals and existing Social Norms. Only when they failed to detect such a match did participants consider Affordances and Features. We present a revised conceptual model based on these results and discuss social media design and theory implications.

Shade dried meat bearing fat (Summungaya) is a popular food product in the western State of Sudan (Darfur). Meat bearing fat was cut into slices and it was hung on a rope inside a storeroom. Meat slices were left for 9 days to undergo fermentation and drying. At the end of the drying process some of the dried strips were stored hung on the rope and the others were ground, kept in sterilized glass and metal container and stored at room and refrigerator temperature. Samples were subjected to microbiological analysis, which were carried at 3 days intervals for 9 days and monthly for three months. The chemical evaluation was determined after a month and 3 months. Drying of the fresh slices revealed a drastic drop in total viable bacterial count (TVBC), coliform, E. coli , and moisture content, while Staphylococci sp. and Salmonella were not detected. After 3 months drying, the TVBC of the hung strips increased from 5.75x10 4 to 4.25x10 5 cfu/g and moulds from 1.53x10 3 to 7.20x10 4 cfu/g as moisture decreased from 8.7% to 4%, however yeasts almost remained constant. The TVBC (5.75x10 4 cfu/g), yeasts (2.00x10 3 cfu/g) and moulds (1.53x10 3 cfu/g) for glass container samples remained constant at both storage temperatures. With respect to metal container samples the TVBC increased from 5.75x10 4 cfu/g to 6.20x10 5 cfu/g, yeasts and moulds remained constant at level of 2.50x10 3 and 2.20x10 3 cfu/g respectively. After one month drying protein, ash and fat content increased. After 3 months drying the product showed slight changes in protein, fat and ash content. The dominant bacteria were identified as Bacillus sp., yeasts as Candida edax and Candida graminis and moulds as Rhizopus nigricans and Apergillus niger . Mycotoxin B2 content (5.8ppb) found in hung strips was less than the permissible level of SSMO. This findings revealed that the production of Sumungaya should be under more hygienic condition. The presence of metabolic compounds from these moulds and their interaction with pathogenic bacteria may lead to the outbreak of food-borne illness.


Abstract This article explores the codeswitching behaviour (into Zulu from English) of three senior teachers and the principal of a KwaZulu boarding school in their interactions with pupils. Following Gumperz (1982), codeswitching is treated as a 'contextualization cue'. In other words, switches from English to Zulu are interpreted as delineating the context for those involved and as guiding the participants' interpretation of what takes place in the interactions. Switches into Zulu are shown to have important academic and social functions of different kinds in the classroom, guiding academic activity and interpretation, and guiding the interpretation of social, relationship‐related information. The implications of these findings for teacher eduction in South Africa (as well as more generally) are then considered. It is argued that priority needs to be given to consciousness‐raising as a means of developing sociolinguistic sensitivity on the parts of aspirant teachers—and essential knowledge for such a pr...


Background The 2014–2016 Ebola epidemic devastated families and communities throughout West Africa. Due to its high mortality rate and infectious nature, most Ebola research to date has focused on healthcare response and interventions; however, little is known about the experiences of Ebola survivors and communities. This qualitative study aimed to better understand the lived experiences of community members, including children, during and after the Ebola epidemic in Sierra Leone. Methods During June 2016 and June 2017, we conducted four focus groups comprised of primary school students, female caretakers, male caretakers, and teachers, and two individual in-depth interviews with local nurses in Calaba Town, a small village outside of Freetown. Interviews were recorded, transcribed verbatim, and coded using a modified grounded theory methodology. Findings All participants shared that they experienced significant challenges during and after the Ebola epidemic. During the epidemic, participants endured daily life challenges pertaining to fear, financial distress, and school closures. They also experienced suffering, loss, isolation, grief, and compromised culture. Confusion and distrust were also prevalent during the epidemic, with participants reporting confusion around Ebola transmission and distrust in the government and healthcare services. We also found that the struggle for food and grief stemming from the loss of loved ones continued more than a year after the epidemic ended. Despite Sierra Leone being declared Ebola-free, stigma and fear persisted and community members shared their continuing distrust of the government due to their actions during and after the epidemic. Conclusions The findings of this qualitative study reveal that the Ebola epidemic was a traumatizing period for the Calaba Town community, and that confusion and distrust toward the government health care system have continued. Future studies should explore the extended impact of the epidemic on communities, including long-term psychological, social, and economic consequences of this outbreak.


OBJECTIVE:To establish a method for the determination of related substances benzaldehyde and toluene in benzoic acid crude drug.METHODS:RP-HPLC method was adopted.The determination was performed on Wondasil TM-C 18 column with mobile phase consisted of methanol-0.02 mol/L ammonium acetate(pH 4.0)(80:20)at the flow rate of 0.5 ml/min.The detection wavelength was set at 254 nm.RESULTS:Benzoic acid,benzaldehyde and toluene could be separated completely.The linear range of benzaldehyde and toluene were 2.0-7.2 μg/ml(r=0.999 5)and 1.75-6.30 μg/ml(r=0.998 9)respectively.The detection limits were 0.05 μg/ml and 0.2 μg/ml.The average recoveries were 100.57%(RSD=0.99%,n=9)and 99.58%(RSD=0.86%,n=9),respectively.CONCLUSIONS:This method is sensitive and accurate,and it can be used for the simultaneous determination of related substances benzaldehyde and toluene in benzoic acid crude drug.

In many countries, it is possible to observe the contradiction between the increase of cross-border flows under the impact of globalization and regional integration and remaining considerable and often increasing barrier ft ictions of the borders. A comparative study of interactions with adjacent regions on different sections of Russian borders revealed a controversial character of the relation betweei crossborder flows and borders' barrier functions. The authors suggest an approach for the evaluation of state borders' barrier function. The capacity of all road-crossing points was estimated and compared with the real flows of vehicles and people. It is shown that the density of crossing points is changing depending on the shills in bilateral relations betweenRussiaand neighboring countries and the intensity of interactions. A typology of Russian borders by their barrier functions and by the importance of interactions with the neighboring countries was developed.


The feasibility of an investigation of the pn --> pn eta-prime reaction by means of the COSY-11 internal target facility is discussed. Appraisals are based on the assumption of the quasi-free reactions of beam protons, circulating in the cooler synchrotron COSY, with neutrons from a windowless deuteron cluster target.


Theoretical basis
Transnational entrepreneurs (TEs) are individuals that migrate from one country to another, concurrently maintaining business-related linkages with their former country of origin and currently adopted countries and communities. TEs are active social actors who enact networks, ideas, information and practices for the purpose of seeking business opportunities or maintaining businesses within dual-social fields, which, in turn, force them to engage in varied strategies of action to promote their entrepreneurial activities (Drori, Honig & Wright, 2009). This case research focused on the ethic, legal and cultural challenges TE has been facing when operating their business across boards.

Research methodology
The data used in this case were collected from mainly third-parties, including the office de la protection du consommateur; Office of consumer protection (OPC), securities and exchange commission (SEC) reports, news as well as marketing materials posted on public media by Sinorama Corp. and Vacances Sinorama. The authors conducted interviews with former employees of Vacances Sinorama to gain the understanding of the owners and the business challenges faced during the years of operation. The authors also communicated with the OPC through to obtain specific case-related information through the Canadian freedom of information channels. Triangulation of such information from multiple resources had been conducted to validate and support the details described in the case content.

Case overview/synopsis
A Chinese immigrant couple migrated to Canada and started Vacances Sinorama Inc. ("Vacances Sinorama") in 2005. The focus of this case is on the expansion of their travel businesses after 2015. In 2016, they established a financing shell company, Sinorama Corporation ("Sinorama Corp."), in Florida, USA, which became the holding company to the operation subsidiaries. Born during the 1970s and raised in Mainland China, the owners were culturally traditional and operated the company with the values and norms from their heritage culture. Vacances Sinorama successfully penetrated the local tourism market using Web-based technology and aggressive low-pricing strategies after the scaling-up strategies. However, Vacances Sinorama was operating in the red for several consecutive years (2015–2018). Sinorama Corp. received additional capital of US$4.4m by listing a portion of its shares on the NASDAQ over-the-counter market during 2016 and 2017. Canadian regulators began to investigate its operational and financing activities in 2017. They found a comingling of client and operation funds, which directly violated Canadian consumer protection laws. As a result of these violations, the license for Vacances Sinorama was nonrenewed in August 2018. The majority of owners fought to overturn the regulators' decision and failed at all levels of appeal, administrative and judicial. This entrepreneurial endeavor ended with Vacances Sinorama declaring bankruptcy in October of 2018.

This paper examines the performance consequences for venture capital-backed (VC-backed) firms when one of their existing VCs withdraws from the investment syndication in the follow-on round. After controlling for the endogeneity of VC withdrawal of follow-on investment, we find that such event decreases the amount of follow-on investment by about 60% and adversely influences the quality of VCs who join the syndication in the follow-on round of investment. The negative signal of VC withdrawal increases information asymmetry, thereby increasing adverse selection risk for follow-on VCs. General-stage VCs and high-status VCs that withdraw send a stronger negative signal compared with VCs specializing in early-stage investing and low-status VCs. Our results show how the dynamics of VC syndication contribute to the valuation of new firms.


Critical Thinking and Argumentation is the 4th level of a textbook series English composition: From Creative Thinking to Critical Thinking designed for Chinese Englishmajor college students. It is an innovative practice for the creative use of the training of critical thinking as a way to teach writing. It brings the concept of critical thinking to the writing process to help learners brainstorm writing topics, to cultivate and develop learners' creativity and to establish a wonderful experimental space for becoming a good writer as well as a critical thinker. By breaking the traditional model of teaching in a constrained content of language and structure, it breaks the walls in the minds of not only EFL learners, but also EFL textbook writers. Zhang Zaixin, the author of the book, is a professor at Beijing Foreign Studies University, who got his MA in Arizona State University and his PhD in Louisiana State University where he taught English writing for six years. Zhang has been showing great concern on the teaching of EFL writing in Chinese colleges. As early as in 1995, he did research on the major problems in the teaching and learning of EFL writing in China. He found that the prominent problems shown from students' writing were a lack of both content and skills in developing supportive details for the main ideas, and he related these problems to the teaching methods which contributed little to students' global idea development and thinking skills (Zhang, 1995). Drawing upon the series of English composition: From Creative Thinking to Critical Thinking, Zhang advances a concept of improving writing through the development of thinking. Combing his studies in critical thinking with a process teaching approach, he focuses, in this book of argumentation, on writing with good logic and reasoning, which adds a higher value of the writing process as well as the outcome. Zhang writes in a democratic style of face-to-face talking, welcoming students to figure out something by themselves rather than forcing them to follow. As an EFL writing textbook, Critical Thinking and Argumentation illustrates many unique features in its preface, unit introduction, key concept explanation, as well as course and exercise design. At the very beginning of the book, he explains in the preface dedicated to the learners of this book, like an opening speech of a teacher in his/her first class, the


Breast cancer is considered as the most common type of cancer among women. The treatment can be more successful when the lesion and its type are diagnosed in the early stages. A biopsy, which is invasive and causes a lot of psychological and financial costs on the patient, can be used to ensure the type of lesions due to the lack of sufficient accuracy of each the previously used method. Thus, a low-cost, non-radioactive, and non-invasive method should be implemented for determining the type of lesion. Based on the recent studies on RF time series, the interactions of this signal with tissue and echo patterns can create useful information about the propagation environment. In this study, RF signals were recorded while stimulating breast tissue, and afterwards the effect of this interaction on the classification of cancerous and non-cancerous lesions was observed by extracting appropriate features from the RF time series. A Supersonic Imagine US system equipped with a linear probe was applied for recording the signal. The data were recorded from two types of agar-gelatin phantom mimicking breast tissue. The data were collected under a fixed probe, as well as static and vibrational excitation. Finally, SVM classifiers were used to classify cancerous and healthy tissues. In addition, the effect of central frequency on this classification was considered. Based on the results, tissue characteristics can add more information to the RF time series and improve classification results. The best result was obtained by 6.4 central frequency ultrafast beamformed data with 98.78±2.77 % accuracy.


An off-line Insulated gate bipolar transistor (IGBT) switching characteristics measurement system was introduced. There are two parts in this system: a test platform and a modeling platform. A man-machine interface based on LabVIEW was adopted on the computer, through which users could choose parameters such as bus voltage, load current, temperature, gate voltage, and gate resistor. The computer performed serial communication with DSP via RS232 interface, controlled the oscilloscope via GPIB interface and recorded turn-on and turn-off current and voltage waveforms. Switching losses models (power function model, power function and polynomial model, neural network model) were established on the basis of testing data. The switching characteristics measurement system has realized IGBT switching losses measurement and losses model establishment and provides switching losses forecast for device users.


Recently preparative liquid chromatography (PLC) has been used more frequently to separate drugs and natural substances. This modern separation methodologies require reliable tools that perform on a high level in terms of efficiency and reproducibility. However, large-scale PLC easily tends to reduce the yield and purity of the product. To promote the separation efficiency of PLC, we need to properly understand the controlling effects of the process, which may enable to predict the process and to improve the design and operation of PLC. Progress in computer technology allows the use of sophisticated models, provided their parameters can be measured. Some hardwares as well as softwares for PLC were already commercially available. In this work, the separation characteristic of PLC will be reviewed and compared on both the software and the hardware.


Near Field Communication (NFC) as relatively new wireless communication technology pushes new challenges to application developers to make their applications easier to use and simpler to operate. This point of view known as usability element. Usability is one of the elements for creating good quality applications. This study aims to analyse the usability of mobile-based application embeds with NFC. We also try to evaluate usability in applications used by children. We developed an application called Receptionist which has a primary function as a communication tool between students, teachers and parents at a middle school. To know the impact of the NFC, the Receptionist input system is designed with two methods, via conventional navigation (using buttons) and via NFC. To understand the usability of each method, we do user testing and questioners on students. The results show, using the NFC there is a significant increase in usability attributes: efficiency, effectiveness, and learnability. On the other hand, there is decreases of user satisfaction comparing to conventional method. In general, this study demonstrates the potential of new input device technologies that can improve the usability of mobile-based applications.

This paper looks at the benefits of drones in agriculture, and their limitations, illustrating from examples how drones operate on farms. Different features of drones are discussed, specifically how they assist farmers in maximizing their harvest by detecting problems early, and managing the crops by using specific cameras to detect pests and water shortages. Two interview were done: one with a strong emphasis on drone camera technology - UVIRCO and the second - Aerobotics - to further illustrate the uses of agricultural drones. The article concludes by recommending that more farmers invest in drone technology to better their agricultural outputs.


In modern time electricity demand is increasing day by day and due to limitations of fossil fuels and other environmental issues the whole world is looking for alternatives. Renewable energy sources are proving their strength. Solar energy is the most important renewable and sustainable energy system. The modelling of solar cell and array is very much time consuming because it has so many complex mathematical equations. Sometimes we need only the solar cell for its applications without going into details of its complex equations . MATLAB has provided a very helpful and handy tool for solar cell in Simscape library that uses the physical language for modelling. But before using that tool It becomes necessary to learn the interfacing between Simscape and SPS tools with the use of some converters. In this paper step by step procedure is shown for modelling of solar array with the use of Simscape library. To extract the Maximum power from solar array, MPPT technique is necessary so in this paper Incremental conductance method is used for MPPT and results are shown in the form of various characteristics of solar array.


We report paleomagnetic results for Leg 49 obtained onboard Glomar Challenger and subsequently in the shore laboratories. The intensity of remanent magnetization of basaltic ocean crust fluctuates with depth at all sites; within-site variation of this property exceeds between-site variation. No significant differences in the remanence intensity of the upper ocean crust occur between magnetic anomalies 13 and 2' or between groups of sites at latitudes 37°N, 45°N, and 63°N. An arithmetic mean intensity of 5.0 × 10~ emu/cm for all Leg 49 basalt specimens is close to previous average values for samples from the North Atlantic Ocean floor. Median destructive fields, weak field susceptibilities, and Konigsberger ratios are comparable with previous results from ocean floor basalts. The Konigsberger ratios show that remanence dominates the magnetization of the upper ocean crust. In seven out of eight holes, the sign of the stable inclination is appropriate to the magnetic anomaly. Values of stable inclination fluctuate with depth. At two sites, abrupt changes in stable inclination together with other paleomagnetic properties make it easy to define distinct magnetic units. At the other sites, it is more difficult to locate boundaries using magnetic evidence alone. Fewer magnetic units than petrographic units are identified in all cases. INTRODUCTION Paleomagnetic measurements on oceanic basement drilling in situ are extremely important in establishing the nature, thickness, and geometry of the magnetized bodies which generate marine magnetic anomalies. Leg 49 drilling took place over a wide geographic area, and the sites were carefully positioned to sample the centers of the sources of well-defined magnetic anomalies. The paleomagnetic results therefore constitute a significant extension to the pre-existing data. The sites sampled form three groups: Holes 407, 408 and 409 on the west flank of the Reykjanes Ridge, Holes 410 and 410A at latitude 45°N, and Holes 411, 412A, and 413 in the FAMOUS area. The immediate objectives of the shipboard studies were to identify variations of the magnetic properties with depth and use them to help distinguish lithologic boundaries. The broader objectives were to compare the magnetic data from different sites and to compare all these data with the results of previous DSDP drilling into basement, with measurements on dredged samples, and with theoretical predictions. These paleomagnetic studies are supported by rock magnetic studies which examine the sources of the remanence and its petrogenetic significance (see Day et al., this volume; Kobayashi et al., this volume). METHODS OF INVESTIGATION Paleomagnetic measurements were normally made on cylindrical cores, 2.54 cm in diameter and between 2.40 and 2.54 cm high, obtained by drilling into the cut surface of the working half of the core. An arrow drawn on the top flat face of each cyUnder indicated the up-hole direction. Samples were taken at a frequency of at least one per 1.5 meter section of core, whenever possible; they were taken only from pieces too long to have overturned in the core barrel. At Holes 411, 412A, and 413, where the recovered basement material was sparse, a few thinner paleomagnetic samples, 1.0 cm in diameter and 2.4 cm high, were used in addition to those of standard size. At Hole 410, nine additional samples of 1.0 cm diameter, 1.0 cm high were taken from small basalt chunks in basalt-limestone breccia. These thinner cores were inserted into Styrofoam plugs for measurement. Shipboard measurements were made using a Digico balanced fluxgate spinner magnetometer, an alternating field (AF) demagnetizer with a two-axis tumbler, and a Schonstedt thermal demagnetizer in which the specimens were heated and then cooled in air. Three specimens known to be magnetically stable were measured on the Digico, which gave results very close to those obtained previously using a Schonstedt spinner magnetometer. Without a fluxmeter, any residual field in the cooling chamber of the thermal demagnetizer could not be measured, but tests on a granitic specimen suggested that such a field did not become important until the remanence intensity had decreased to 5 × 10~ emu/cm. Subsequent measurements were made onshore using an identical Digico spinner, an AF demagnetizer with a two-axis tumbler, and a large thermal demagnetizer, where the field in the specimen chamber is


Retention percentage of three fractions of coarse particulate organic matter (MOPC) and discharge effect over retention of particulate organic matter (MOP) were studied during five months in three sectors of a tropical mountain stream, at Eastern hills of Bogota ~ Colombia. The tropical condition of the system, showed a pattern of constant discharge although could be a different period from low and high discharge. Results showed as average value of retention percentage was high, with a negative association between flow magnitude and percentage of retention for each MOPG 34 Articulo _Retenci6n de materia orgdnica particulada gruesa en una quebrada de montana tropical.

It demonstrates how well preservated tropical mountain streams can display a high bed heterogeneity which helps to retention of great amounts of MOPG same to La Vieja creek.


We propose a TDOA-based algorithm for source localization on rigid surfaces. This allows the conversion of readily available large surfaces into touch interfaces using surface-mounted vibration sensors. To achieve this, we characterize the arrival of each sensor-received signal by the arrival times of its frequency components. To estimate the arrival time of each frequency component, we first model each component as a harmonic random process. A kurtosis sequence, which exhibits a sharp rising edge when the signal begins to deviate from the background noise, can then be obtained for each component. By accurately estimating the starting point of the rising edge, our algorithm can avoid the uncertainty due to gradual noise-to-signal transition. Experiment results show that the proposed algorithm achieves better localization performance than existing techniques on large surfaces.


CASE
A 20-year-old woman presented with symptomatic instability secondary to traumatic anterior cruciate ligament (ACL) rupture. Arthroscopic ACL reconstruction was performed using a 4-strand semitendinosus autograft harvested using a posterior approach. At her 2-month follow-up, a painful mass was palpable, and a hernia of the medial gastrocnemius was confirmed by ultrasound. This was treated with fascial closure. The clinical outcome was excellent at final follow-up.

CONCLUSION
This is the first case reported in the literature of a muscular hernia after an ACL reconstruction using a posterior harvest of the semitendinosus. Surgeons must be aware of this specific complication and how it may be addressed.


BIPV refers to building integrated photovaltaics, while BAPV refers to building attached photovaltaics. BAPV appears earlier than BIPV, as traditional building mounted photovaltaics. Since BAPV design is mainly about photovoltaic system design, thus it cannot satis-fy the requirement of BIPV design. The paper explores the computer-aided design approach to BIPV using Ecotect and PVsyst. This approach comprises of 5 stages, including data collection, site planning, conceptual design, structural and system design as well as engineering design.Among the 5 stages, the first three are accomplished by architects, the fourth accomplished by both architects and electrical engineers, and the last accomplished by engineers from related disciplines.


We report the measurement of the electromagnetically induced transparency (EIT) with Rydberg states in ultracold 40 K Fermi gases, which is obtained through a two-photon process with the ladder scheme. Rydberg – EIT lines are obtained by measuring the atomic losses instead of the transmitted probe beam. Based on the laser frequency stabilization locking to the superstable cavity, we study the Rydberg – EIT line shapes for the 37s and 35d states. We experimentally demonstrate the significant change in the Rydberg – EIT spectrum by changing the principal quantum number of the Rydberg state (n = 37 = 52 and l = 0). Moreover, the transparency peak position shift is observed, which may be induced by the interaction of the Rydberg atoms. This work provides a platform to explore many interesting behaviors involving Rydberg states in ultracold Fermi gases.


Mouse C3H embryo cells were transformed in vitro by avian sarcoma virus Bratislava 77 (B77) released scantily from a mouse cell line transformed earlier by the same virus. B77 virus transformed C3H embryo cells contained B77 viral genome and were transplantable into syngeneic as well as allogeneic DBA/2J young mice in which autochthonous sarcomas were induced. Tumors in both strains of mice were virogenic. The probable reasons for an increased transformation capacity of B77 virus in mammals are discussed.

Javanese language is the language used by some regions in Java, from the west to the east Java. Even though, Javanese people used same language, the differences still appeared in the vocabularies and pronunciation when they make conversation in their daily activities such as that they used on facebook to update statuses and give comments.

The aim of this study is to describe the Javanese dialect used on facebook to update status and give comment then each word is compared with the Standard Javanese. It is limited on the vocabulary in four parts of speech (noun, verb, adjective and adverb). This study used qualitative research where the observation is used as the technique of collecting data and documents as the instrument of the observation.

The writer found that there were about forty one Javanese words used by Javanese to update status and give comment on facebook. Those vocabularies were divided into eleven nouns, sixteen verbs, six adjectives, and eight adverbs. From those data, it could be concluded that there were sixteen different vocabularies (nine of them are totally different vocabularies and seven of them are different vocabularies by omitting phoneme).

Although Javanese people use the same language, they have differences in using Javanese language. The differences could be found on their vocabulary in their daily activities like what they used on facebook to update status and give comment. This differences was caused by the regional factor that influence their dialect, then became their identity that make them unique and different each other.


Background: It has been shown in studies that there are symptomatic improvements in patients treated with Daflon 500, but studies on its effect on the venous valve are limited to experimental animal studies. In this study, the effect of Daflon 1000mg/day on saphenofemoral junctional (SFJ) valve competence and reflux was investigated. Methods: In this prospective study, 76 patients with insufficiency in the SFJ were treated with 1000mg Daflon daily. SFJ diameter and reflux degree of patients were evaluated and compared with venous Doppler ultrasound before and after 6 months of treatment. Results: The mean age was 46.2±8.6; the female was 48 (63.2%); the mean follow-up was 6.4±2.7 months. Pre- and post-treatment diameters of SFJ were 6.32±1.76 (3.8-10.5) and 5.78±1.61 (3.5-10) mm, respectively. This was not statistically significant (P=0.096). After the treatment, patients with SFJ reflux decreased from 100% to 82.9%, and 17.1% patients recovered from SFJ reflux. This was statistically significant (P=0.016, OR:0.031, 95% CI: 0.002-0.527). Similarly, the number of patients with severe GSV reflux decreased from 40.8% to 21%, this was also statistically significant (P=0.049 and P=0.009). Patients with leg pain decreased from 51.3% to 14.5%, this was statistically severely significant (P<0.001, OR:0.20, 95% CI:0.09-0.44). Patients suffering from ankle swelling and itching were also recovered in a significant number (P=0.0031 and P=0.0029). Conclusion: Six months' use of Daflon 1000mg/day reduces the reflux of SFJ and GSV, and provides symptomatic relief. In this study model, there is no significant improvement in the SFJ valve diameter.

Electrocardiographic monitoring of a 24 year old male, who sustained household electric current injury, showed low voltage ECG complexes, varying degrees of atrioventricular (AV) blocks, and ventricular fibrillation. The low voltage ECG complexes and varying AV blocks disappeared spontaneously and ventricular fibrillation reverted to normal after cardioversion.


The International Care Ethics Observatory recently hosted a panel event on the theme of this Editorial. The case of Charlie Gard involved differences of opinion regarding what was in the 'best interests' of this seriously ill infant. His parents wanted Charlie to have access to experimental treatment in the United States, and local doctors decided that this would result in more harm than good for Charlie. The courts agreed with the doctors and the family were prevented from travelling abroad. Charlie eventually died in a hospice on 28 July 2017. Members of the panel brought a range of different perspectives to bear on the case highlighting the complexity and challenges and demonstrating the value of an inter-disciplinary exploration. The panel comprised a media and communication academic, a lawyer, a bioethicist and a paediatric clinician and researcher. Ranjana Das presented an analysis that surprised many in the audience. She urged a critical scepticism about the source of, and motives of those engaged in, social media. In communication following the panel event, she highlighted five points. First, she stated that her analysis of Twitter data: revealed that

This article reports comparison results from studying the
 alignment of selected metadata models, used to manage E‑Learning
 Materials (ELM) in the medicine and healthcare education, against
 the accreditation standards of the European Accreditation Council
 for Continuing Medical Education (EACCME). The study aims to (1)
 illustrate the variety of application profiles developed as metadata
 models in that field, (2) identify the alignment of the metadata
 models with the criteria set by the EACCME. This study com¬pared
 several application profiles, developed based on established
 metadata standards, using an evaluation matrix created using the
 accreditation criteria set by the EACCME. Further technical criteria
 were added to compare between the metadata models and their
 alignment with the new techniques used for publishing data online.
 Such techniques aid in the searchabililty and discovery of online
 content via the internet. Therefore, the use of XML and RDF
 technologies combined with the use of ontologies and controlled
 vocabulary was emphasized in the implementation of many metadata
 models. One limitation faced during conducting this research was the
 poor documentation of the methodology for designing the metadata
 models. Despite this, it is apparent that the EACCME criteria can
 work as best practices guidelines for describing the content of
 digital libraries with medical and healthcare content in order to be
 accredited later on. The study showed that the medicine and
 healthcare educational content requires specialized metadata models
 that consider having specific properties such as clinical history
 and expiry time of its material shown in some of the application
 profiles. Further research should be conducted to evaluate the
 completeness and conformity of applying the application profiles in
 digital libraries and online repositories to the standards'
 guidelines.


The paper discusses the application of a signal processing technique known as independent component analysis (ICA), also called blind source separation, to multivariate financial time series. The key idea of ICA is to linearly map observed multivariate time series (such as a portfolio of stocks) into a new space of components that are statistically independent. The authors apply ICA to daily returns of the 28 largest Japanese stocks and compare the ICA results to principal component analysis. Their results indicate that the estimated ICs fall into two categories, (i) infrequent but large shocks (responsible for the major changes in the stock prices), and (ii) frequent but rather small fluctuations (contributing little to the overall level of the stocks). They show that the overall stock price can be reconstructed surprisingly well by thresholding the weighted ICs and using, on average, only one such shock per quarter. In contrast, when using shocks derived from principal components instead of independent components, the reconstructed price does not resemble the original one. The technique of ICA is shown to be a potentially powerful method to analyze and understand driving mechanisms in financial time series.


Due to their ability to model the manifold of natural images, generative adversarial networks (GANs) have been adapted to semi-supervised learning and shown promising results. Using this property of GANs, manifold regularization has been incorporated into feature-matching GANs (FM-GAN) [14] and shown improvement over FM-GAN. In this work, we present a novel approach for performing manifold regularization in semi- supervised classification using the FM-GAN framework. Our approach, mixup manifold regularization (MUMR), regularizes the networks to favor linear behavior so that linear interpolations of noise vectors lead to linear interpolations of the associated predictions. We show that our approach is able to achieve state-of-the-art results when compared to other GANs- and perturbation-based approaches.


Field surveys of hot springs were carried out at four Spas. Observations were made on the temperature, pH, dissolved oxygen and sulfide concentrations, current velocities, and the habitats of three (A, B, C) types of sulfur-turfs. The B-type (rods) was not present, while the A-type (sausageshaped bacteria) grew only in the streams. In contrast, the C-type (filamentous bacteria) inhabited only the pools of hot spring water. Ranges of dissolved oxygen concentrations in situ were 6 to 31 μM for the A-type and 6 to 110 μM for the C-type sulfur-turfs. The sausage-shaped bacteria (main bacterial component of the A-type sulfur-turf) had peritrichous flagella which were not present in the filamentous C-type bacteria. It was suggested that the A-type sulfur-turf preferred the stream to the pool because of this bacteria's low level and narrow range of oxygen requirement and its ability to form aggregates by intertwining flagella, even in flowing water. In contrast, the C-type preferred the pool rather than the stream due to its wide range of oxygen requirement and its inability to form colonies in rapidly flowing water.


Enantiomerically pure or enriched sulfoxides with a stereogenic S-atom are of great importance. The second highest selling drug in the USA in 2010 features this structural motif. S-chiral sulfoxides are also used in asymmetric synthesis, either as stoichiometric carriers of chiral information or as ligands in transition-metal catalyzed reactions and organocatalysis. Common accesses to such sulfoxides include the resolution of racemic material, the asymmetric oxidation of sulfides, the elaboration of already existing sulfoxides, and nucleophilic substitutions at sulfur electrophiles. The preparation of non-racemic products by the desymmetrization of achiral substrates is quite generally appealing for two reasons: 1) Prochiral or meso-configured compounds are often readily accessible by bidirectional synthesis. 2) Particular high enantiomeric excesses are possible if the desymmetrization is followed by a kinetic resolution. Figure 1 depicts selected prochiral monosulfoxides, in which the sulfur atom became a stereocenter through enzymatic monofunctionalizations of one of the two side-chain functional groups. Recently we desymmetrized the prochiral dibromo alcohol 5 by an asymmetric bromine–magnesium exchange (Scheme 1; ! 6 + iPrBr). Theorizing about the underlying mechanism we wondered whether a similar reaction de-


Limited evidence suggests increased efficacy of rhG‐CSF by subcutaneous (SQ) compared with intravenous (IV) administration. To examine the possibility that rapid elimination of IV rhG‐CSF could substantially shorten the duration of systemic exposure and could explain a difference in pharmacodynamics, we characterized the pharmacokinetic profile of IV rhG‐CSF for comparison to that previously reported for SQ administration. Twelve children were randomly assigned to receive 10 or more days of IV rhG‐CSF at dosages of 5 or 10 μg/kg a day beginning 24 hr after chemotherapy. Enzyme‐linked immunosorbent assay (ELISA) was used to measure rhG‐CSF concentrations in timed serum samples on days 1 and 10. Pharmacokinetic parameters were estimated by nonlinear, least squares regression. All serum concentration‐time profiles were best described by a two‐compartment model of elimination. Mean t1/2β values ranged from 3.68 ± 0.86 to 22.4 ± 12.0 hr. ANC was correlated with log CLT (r = 0.72, P < 0.05), and inversely with log dose‐adjusted AUC (r = −0.75, P < 0.05) and log dose‐adjusted Cmax (r = −0.65, P < 0.05). Estimated duration of serum rhG‐CSF concentrations above 1 ng/ml exceeded 24 hr for all but the 5 μg/kg cohort on day 1. Pharmacokinetic parameters of IV rhG‐CSF are similar to those previously reported for SQ administration in children treated with myelosuppressive cancer chemotherapy. Daily IV administration should be suitable alternative route of administration in this patient population. Am. J. Hematol. 54:124–130, 1997 © 1997 Wiley‐Liss, Inc.


Introduction: The myocardial work (MW) is a new echocardiographic method, based on the pressure-strain loop, which allows quantifying the cardiac performance. On the other hand, the pulse wave velocity (PWV) evaluates arterial stiffness, knowing that as the stiffness of an artery increases, the transmission velocity of the anterograde and the retrograde sphygmic wave increases


A new general strategy for measuring similarity between proteins is introduced. Our approach has its roots in computational linguistics and the related techniques for quantifying and comparing content in strings of characters. The pairwise comparison of proteins relies on the content regularities expected to uniquely characterize each sequence. These regularities are captured by n-gram based modelling techniques and in the sequel are contrasted by cross-entropy related measures. In this very first attempt to fuse theoretical ideas from computational linguistic within the field of bioinformatics, we experimented with different implementations having always as ultimate goal the development of practical, computational efficient algorithms. The experimental analysis provides evidence for the usefulness of the new approach and motivates the further development of linguistics-related tools as a means to decipher the biological sequences.


We propose a new attitude acquisition method based on the Bayesian bootstrap filtering approach using dual star sensors. The proposed method estimates the right ascension and the declination pointed by each star sensor in the reference coordinate system using the measurement of the number of stars inside the FOV (field of view). The system and the measurement models are highly nonlinear functions of the state. Moreover, measurements are drawn from a finite nonnegative integer set rather than from real numbers, and the well-known extended Kalman filter cannot be used. We propose to apply the Bayesian bootstrap filtering technique assuming that the measurement noise has an arbitrary probability mass function. According to our simulation, the proposed method is computationally faster, and acquires the attitude quickly compared with more traditional triangular point-pattern matching techniques.


When an oxide surface is placed in water, a difference in potential across the interface occurs due to dipole orientation. Hydroxyl groups or bound oxygen atoms on the oxide surface will orient adjacent water molecules which balance the dipole charge. This occurs over some small distance called the electrical double layer. Trace amounts of high field strength ions present in the vicinity of the double layer can have significant effects on the double layer. When there is movement of the oxide surface with respect to the water, a shearing of the double layer occurs. The electrical potential at this surface of shear is termed the zeta potential. The impetus for this study was to document the zeta potential behavior in water of two optical materials. (1) a multicomponent phosphate glass; and (2) Zerodur, a silicate glass-ceramic.


The Latin treatises on the Hindu art of reckoning which antedate the XIVth century are sufficiently rare so that the addition even of anonymous works to the available literature on this subject is highly desirable. Doubtless the earliest of these algorisms are the two ascribed to AL-KHOWARIZMI, published by BONCOIMPAGN1 (i), the first a translation and the second probably an adaptation of the Arab's lost work on arithmetic. Of the XIIth century also are the fragments on multiplication and division by N. OCREAT (O'CREAT) (2), and the algorism published by NAGL (3) and again by CURTZE (4). Of the algorisms of the XIIIth century the three most widely used were the Carmen de algorismo (5) by ALEXANDER DE VILLA DEI, SACROBOSCO'S Algorismus vulgaris (6), and LEONARD OF PISA's Liber abaci (7). The A Igorithmns demonstratus of GERNARDUS (8), and the treatises ascribed to JORDANuS NEMORARIUS (9), all of the XIIIth century, were not widely

Introduction. Hepatitis C virus (genotype-3) causes acute and chronic hepatitis infection predomination in India. The infectious phase of the virus requires various host factors for its survival and subsequent viral particle production. Small RNA molecules like microRNA-122 (miR-122) are one such factor mostly present in the liver and play a supportive role in viral replication. Objective. In this study, diagnostic potential of miR-122 is evaluated in the sera of chronic hepatitis C patients. Methods. miRNAs were isolated from the sera samples of patients as well as controls and miR-122 expression was quantified by real-time PCR. Results. A significant augmentation was observed in the level of circulating miR-122 (median level, 0.66 versus 0.29, P = 0.001) in patients compared to controls with ROC value of 0.929 ± 0.034 (P < 0.001). Interestingly, miR-122 level also depicted a significant positive correlation with serum ALT (r = 0.53), AST (r = 0.44), and viral load (r = 0.52). Conclusion. The study thus unveiled the role of miR-122 as a plausible diagnostic biomarker during HCV genotype-3 infection in India.


Most of the existing studies on musical practice are concerned with instrumentalists only. Since singers are seldom considered in research, the present study is based on an online-sample of amateur vocal students (N = 120; 92 female, 28 male). The study investigated the correlations between personality traits, flow-experience and several aspects of practice characteristics. Personality was represented by the three personality dimensions extraversion, neuroticism and psychoticism, assessed by Eysenck's Personality Profiler as well as the trait form of the Positive and Negative Affect Schedule. 'Flow-experience,' 'self-congruence' and 'fear of losing control over concentration,' assessed by the Practice Flow Inventory, served as variables for flow-experience. The practice motivation was measured by the Practice Motivation Questionnaire in four categories ('self,' 'group,' 'audience,' 'teacher'). In addition, the Practice Behavior Questionnaire was used to provide an insight into the practice situation and behavior of singing students. The results show significant correlations: participants with high extraversion-scores experience significantly more flow than less extraverted persons, whereas lesser flow-experience seems to be related to high neuroticism-scores. Nevertheless, there is no influence in flow-experience concerning singing style ('classical' or 'popular'). The longer the practicing time, the more likely students are to achieve flow-experience. However, older singers tend to have less flow-experience. Consequently, singers seem to differ in their personality and practice behavior compared to other musicians. Most of the findings show that having control over one's instrument is decisive for achieving a performance of high quality, especially for singers. On the other hand, certainty in handling an instrument is essential to arouse a flow-feeling. However, flow-experience seems to be common mainly with amateur singers. In conclusion, this offers a starting point for new research on the psychology of vocalists in greater depth.

Eosinophilic gastroenteritis is a rare inflammatory disease characterized by diffuse or scattered eosinophilic infiltration of the gastrointestinal tract. Furthermore, i t is rarely associated with eosinphilic infiltration of gallbladder. A 30-year-old man was repeatedly admitted to the hospital with recurrent biliay colic. An endoscopic ultrasonograpy revealed sludge of gallbladder, and laparoscopic cholecystectomy was performed. Histological examination of the cholecys tectomy specimen revealed no calculus, and marked eosinophilic infiltration of the gallbladder. There was no peripheral eosinophilia and history of allergy. The patient became asymptomatic. How ever, one month later he presented with a new type of epigastric pain unlike the previous ones that he had. Additional biopsies of the stomach and duodenum showed focal mucosal eosinophilic infiltratio n, and it was diagnosed eosinophilic gastroenteritis in conjunction with eosinophilic cholecystitis. The patient was treated with prednisolone (1 mg/kg) and improved.(Korean J Med 69:S758-S762, 2005 )


There has been renewed clinical interest in gout secondary to the recent advances in the understanding of its cellular inflammatory mediators, which have led to new and emerging therapies for treatment. The role of advanced imaging in gout is currently evolving to compliment modern clinical challenges in the treatment of gout. Furthermore, the clinical diagnosis of gout remains potentially challenging, especially in the setting of an atypical presentation and advanced imaging is often utilized in these circumstances. This article seeks to provide a timely review of the magnetic resonance features of chronic tophaceous gout in a pictorial exhibition, as well as provide a future perspective of the utilization of advanced imaging: computed tomography, MRI and ultrasound in the clinical management of gout.


In this paper, we consider one optimal control problem with a multipoint quality functional described by a system of nonlinear hyperbolic equations with Goursat boundary conditions. Using a modified version of the increment method, various necessary first-order optimality conditions such as the Pontryagin maximum principle and the linearized maximum condition are proved.


Summary form only given. Microdischarges (MDs) are being investigated for a variety of applications including hydrogen production for portable fuel cells, microreactors and displays. In portable fuel applications, major system issues include development of practical and safe methods to produce H2 with low lag-times. H2 production from feedstock gases like NH3 typically requires high gas temperatures for thermal decomposition. Due to their high power densities (>10s kW/cm-3) MDs provide an intense source of electron impact dissociation as well as high gas temperatures (>1000 K) for thermal dissociation. By operating at pressures up to and including atmospheric, reformation of N2 and H2 from the dissociation products by three body reactions can be efficient. In this paper, results from a computational investigation of production of H2 from atmospheric pressure microdischarges in Ar/NH3 mixtures will be discussed. The computational platform is a 2-dimensional plasma hydrodynamics model having an unstructured mesh to resolve non-equilibrium electron, ion and neutral transport using fluid equations. Sheath accelerated, beam-like electrons are resolved using a Monte Carlo simulation. A compressible Navier-Stokes module provides the bulk fluid velocities and temperatures. The devices we investigated are cylindrically symmetric sandwich type reactors with characteristic dimensions of 100s mum at high pressures (few 100s torr to atmospheric). Results from a parametric investigation of power (up to 10s W), flow rates (residence time of a few mus) and Ar/NH3 ratios will be discussed with the goal of maximizing the conversion of NH3 to H2 while minimizing the required power


NONUNIFORM MEMBRANES IN CAPACITIVE MICROMACHINED ULTRASONIC TRANSDUCERS Muhammed N. Şenlik M.S. in Electrical and Electronics Engineering Supervisor: Prof. Dr. Abdullah Atalar January 28, 2005 Capacitive micromachined ultrasonic transducers (cMUT) are used to receive and transmit ultrasonic signals. The device is constructed from many small, in the order of microns, circular membranes, which are connected in parallel. When they are immersed in water, the bandwidth of the cMUT is limited by the membrane's second resonance frequency, which causes an increase in the mechanical impedance of the membrane. In this thesis, we propose a new membrane shape to shift the second resonance frequency to higher values, in addition to keeping the impedance of the membrane as small as possible. The structure consists of a very thin membrane with a rigid mass at the center. The stiffness of the central region moves the second resonance to a higher frequency. This membrane configuration is shown to work better compared to conventionally used uniform membranes during both reception and transmission. The improvement in the bandwidth is more than %30 with an increase in the gain.

In the first experiment, binaural diplacusis for harmonic three‐component (amplitude‐modulated signals has been measured. There appears to be a good agreement between diplacusis for complex signals and the average of the pure‐tone diplacusis for its spectral components. In all cases, the pitch of the stimuli used roughly agreed with the pitch of the common, but nonexistant, fundamental. Apparently, the pitch of the separate components is more important than their frequency. Conclusively, the origin of binaural diplacusis cannot be found in a peripherally located mechanism, but in some higher center. In the second experiment, the pitches of inharmonic amplitude‐modulated signals were matched monaurally with those of harmonic signals. The experiment gives direct quantitative information of the pitch deviations which have been found regarding the time‐fine‐structure theory. These deviations increase progressively with the rate of inharmonicity of the signal and decrease with decreasing intensity and modulation depth. The results suggest that the deviations are due to neural interaction mechanisms and thus can not be described in simple mathematical formulas.

Abstract Dual-frequency Identification Sonar (DIDSON) is increasingly used as a fish monitoring and enumeration tool, but many studies do not evaluate potential observer biases. In this project, we assessed inter-observer differences in the identification and enumeration of adult Pacific lamprey (Entosphenus tridentatus) imaged with DIDSON passing a large dam fishway. Six trained viewers independently identified lamprey observation 'events' in the same ∼ 12 h of DIDSON data collected at several fishway locations using two sonar orientations. Among-viewer variability in lamprey enumeration was high and viewer agreement on individual lamprey was often low. A total of 274 unique potential Pacific lamprey events was identified, but individual viewers scored only 89–173 events each (mean = 131, CV = 24%) or 32–63% of the total. Viewer identification rates (events/h) varied several-fold at some sites which we attributed primarily to event non-detection rather than species misclassification. Identification differences were related to viewer confidence, image duration, total fish density, and sonar orientation. Among-viewer agreement was highest in standard-orientation deployments lateral to the swimming lamprey, where images appeared as though acquired from overhead. Imagery in standard orientation had longer event duration and enhanced detection of anguilliform swimming, the most important characteristic for distinguishing Pacific lamprey from other species. Lamprey events observed in rolled orientation (sonar rotated 90°) tended to be short duration with foreshortened head- or tail-first images that reduced viewer confidence. Our results highlight the importance of quality control assessments in acoustic imaging studies, especially those targeting cryptic species and those conducted in hydraulically challenging, multi-species environments.


Fiber metal laminates (FMLs) are made by sandwiching a fiber-reinforced composite between thin layers of metal. FMLs are modern materials utilized in the manufacture of automobiles and aircraft because of their improved mechanical behavior compared to conventional metallic alloys. In the current study, different fabrics, that is, jute (J), glass (G), carbon (C), basalt (B), and aramid (A) were used as reinforcing components for composites that were sandwiched between two aluminum (Al) alloy sheets as a metal component in the proposed FMLs. The effect of hybridizing J-reinforced composite with different declared fabrics on the tensile response of the designed FMLs was experimentally investigated. The proposed FMLs were created using manual lay-up and compression casting techniques. Complex proportional assessment (COPRAS) was adapted to find the best FMLs structure that achieved the optimum tensile properties. The Al/2C/4J/2C/Al and Al/8J/Al structures were ranked first and last, respectively, based on COPRAS results.


An experimental investigation of the effects of varying flapping kinematics on the mean lift produced by an insect-like flapping wing in hover is presented. This was performed with application to flapping-wing micro-air vehicles (FMAVs) in mind. Experiments were accomplished with a first-of-its-kind mechanical flapping-wing apparatus capable of reproducing a wide range of insect-like wing motions in air on the FMAV scale (~150 mm wingspan). This apparatus gives an insect-like wing the three controllable degrees of freedom required to produce the three separate motions necessary for mimicking an insect-like flapping-wing trajectory: sweeping (side to side), plunging (up and down), and pitching (angle of attack variation). Lift was measured via a force balance while the following kinematic parameters were varied: flapping frequency (f ), angle of attack at mid-stroke (αmid), timing of pitch reversal with stroke reversal (rotation phase), stroke amplitude (Φ), and plunge amplitude (Θ). Results revealed that mean lift scaled with f   1.5 and varied proportionally with Φ. A pitch reversal advanced by up to 5 per cent of the flapping period relative to stroke reversal was found to maximize mean lift, and delayed pitch reversals were detrimental to mean lift. Of the parameters tested, mean lift was also maximized for αmid = 45° and Θ = 8.6°.
