DOES AN AFRICAN cultural studies exist? If so, is it a unified field of study? What links does this domain / domains--or perspectives within it/them--have with the First and Second World metropoles? A perusal of the World Wide Web identifies an explosion of African sites in 1996, mainly from South Africa, in which these questions are occasionally asked, but only partially resolved. (1) The UNISA Web site, for example, has valiantly listed the rather vexing and tense interchange between Christo van Staden (1996, 1997) and Arnold Shepperson (1996) which occurred in Communicatio over African intellectual origins and discussions of cultural studies. Questions on the historical lineage of cultural studies offer one trajectory of current discussion (McNeil 1997). Another offers an "alternative account" of origins (Wright, 1998:39). Handel Wright's decentring of the seminal influence of the Birmingham Centre for Contemporary Cultural Studies (BCCCS), was published in the first issue of the European Journal of Cultural Studies. Wright is a Kenyan and educationist working at the University of Tennessee. He locates early forms of cultural studies in Russian culturology of the 1920s, the Harlem Renaissance, the Negritude Movement of the 1930s and the Kamiriithu community project in Kenya in the late 1970s. These, and other "unnamed" cultural studies are present, he argues, in the "absence of Africa in genealogies" of the field. Wright might have added that even those initiatives which are `named' are often ignored by different constituencies competing for the soul of cultural studies. Wright's cites Manthia Diawara's (1992) notion of "performative acts" as a central component of an African cultural studies. This orientation separates Wright's approach from cultural studies solely as an academic discipline. It also perhaps asserts a unity and area--specificity where one does not really exist. However, if community-based performative acts are indeed a criterion of African approaches, then some Southern African interventions should be listed amongst these precursors to cultural studies (Baxter, 1992; Dalrymple, 1987; Hoosain, 1984; Steadman, 1985; Kerr, 1995; Journal of Communication Inquiry, 1988). Some of these "Other, non-British origins" (Wright 1988:39) were elaborated from local South African frames of reference and performance with regard to labour issues and class struggle (eg. Sitas, 1984; Von Kotze. 1988). Others rearticulated a kind of culturalist Marxism, mixed with cultural theory and materialist semiotics, into not only analysis of local contexts, but also into strategies for political action. Many of these differently-inflected applications linked the academy to the community, rather than necessarily assuming the dichotomy between the head and the hand as Wright has noted of the Western, and especially the US, experience. Unlike the UK, USA, and Kenya, various kinds of cultural studies in South Africa can claim an affirmative application in terms of praxis and the trajectory of history, with regard to both the micro- and macro-levels of ideological engagement. As currently "unnamed" applications, Wright might like to see them moved to the `named' within international genealogies of the field. It is not my intention here to make a claim for South African cultural studies--of which there are many kinds--but to revisit the debate from specifically African perspectives. A brief history of cultural studies may be in order. Contemporary Cultural Studies was the name popularised by BCCCS in the mid-1950s as an oppositional academic orientation. The field spread globally from there both geographically and disciplinarily. Its penchant for theoretical incorporation by disciplines ranging from history, geography, literature, and politics to accounting is legion. (2) Most of the ensuing studies were about power relations, social and class struggles, and the ways in which meanings are made and contested in discursive contexts of meaning formation. …


The use of ultrafiltration to concentrate the microbial transglutaminase(MTG) from fermentation liquid was studied.The results showed that the maintaining of initial pH value of fermentation liquid at 7,use of polyethersulphone(PES) membrane with molecular weight cut off(MWCO) of 30 kDa,and four times concentrated fermentation liquid,the MTG yield rate could reach ideal value.The change of the protease activity in the liquid was also analysed.The(protease) activity in the liquid increased with the concentrate times,but it changed little after the liquid being concentrated four times.Finally,membrane flux could be recovered 98.12% after the washing of membrane by NaOH solution(pH 11)for 50 minutes.


The paper introduces a novel method of injecting additional motivation to team projects. Teams of students, engaged in a variety of different assignments are encouraged to learn while creating their own audio-visual media; they are required to prepare and edit a short video documentary as a replacement for the more conventional written or oral report. Using survey data, collected over several years at two separate UK universities, the authors provide evidence that this medium generates much needed engagement, help teams to bond and promotes a deeper understanding of the subject matter. An additional benefit is that the assessment process is considerably less tiresome for the academics. There appears to be vast potential for transferability of this method to many different applications, disciplines and age groups, but while the idea may sound attractive to many lecturers, it marks a significant departure from the norm. The authors have, therefore, created an easily accessible 'toolkit' resource that focuses on issues faced by a new adopter based on their own experience and on feedback from staff and students who participated in the pilot projects. The 'toolkit' incorporates appropriate resources, including teaching and assessment materials, with example projects taken from the science and engineering subject areas


In my thesis, I argue that Aristotle's causal pluralism in conjunction with his hylomorphic account of mental states solves the exclusion problems for mental causation.
 The exclusion problems are the result of a causal tension between the principle of Causal Closure (the thesis that caused physical events have sufficient physical causes) and the principle of Anti-reductionism (the thesis that mental properties and physical properties are distinct). The first exclusion problem is that Causal Closure excludes any non-physical causal influences on physical effects. The second exclusion problem shows that if one also holds any version of supervenience theory between mental and physical properties, mental states cannot cause other mental states. Denying either Causal Closure or Anti-reductionism would help to solve the problem.
 Many consider Causal Closure in a stronger position than Anti-reductionism. However, I argue that there is good reason to deny Causal Closure and retain Anti-reductionism. This is only the first step. This just means that other, non-physical causes can influence the physical domain. But it says nothing about what these causes are or how they are related to their effects and perhaps other causes.
 I suggest that a way forward is through causal pluralism, but, after putting forward a version of causal pluralism, I show it is still unclear how causes are related to other causes; in particular, how a mental cause is related to its underlying neural state.
 I argue that Aristotle's hylomorphism helps with understanding how a mental cause is related to its underlying base, and his causal pluralism helps with how to understand a plurality of causes in mental causation. Aristotle's metaphysics of causation show how each of the causes are related to one another and how they are related to their effects. These insights are applied to mental causation and the exclusion problems.


OBJECTIVES/GOALS: Our long-term goal is to improve the clinical outcomes of patients with status epilepticus through increasing the level of evidence surrounding guidelines. The specific objective of our proposed work is to compare the outcomes and adverse drug events between the Neurocritical Care and American Epilepsy Society levetiracetam dose recommendations. METHODS/STUDY POPULATION: This is a retrospective, single site, cohort study comparing outcomes of hospitalized patients with status epilepticus treated with levetiracetam bolus at the University of Kansas Health System. Patients outcomes will be compared based on levetiracetam bolus dose received. The primary outcome will be seizure reoccurrence within 24 hours. Secondary outcomes include number of additional anti-epileptic drugs administered, cumulative dose of benzodiazepines administered within 24 hours of levetiracetam bolus administration and incidence of adverse drug reactions. All study data will be extracted retrospectively from the EPIC chart review following patient list generation through the HERON i2b2 database query. RESULTS/ANTICIPATED RESULTS: Aim 1 will characterize levetiracetam dosing among patients admitted to the University of Kansas Medical Center for status epilepticus during routine clinical care. We hypothesize that given the inconsistency in dosing recommendations from various professional societies and drug references, we will observe inconsistent dosing of levetiracetam among those hospitalized due to status epilepticus. Aim 2 will evaluate effectiveness and safety across the various levetiracetam doses. We estimate that adherence to the higher weight-based dosing recommendations of the 2016 American Epilepsy Society guideline may result in improved outcomes with a similar frequency and severity of adverse drug events compared to lower/fixed-dose levetiracetam dose recommendation of the 2012 Neurocritical Care guideline. DISCUSSION/SIGNIFICANCE: Notable inconsistencies across the dosing recommendations for levetiracetam exist between the guidelines for treatment of status epilepticus and commonly used tertiary drug information databases. This variation in guidance may lead to differences in dosing and warrants further exploration to better support the management of status epilepticus.


We characterize the rearrangement-invariant hull, with respect to a given measure $\mu$, of weighted Lebesgue spaces. The solution leads us to first consider when this space is contained in the sum of $(L^1 + L^\infty)(R, \mu)$ and the final condition is given in terms of embeddings for weighted Lorentz spaces.


This research investigates the impact of teaching Shakespeare to below-grade-level readers in an English Language Arts classroom on Chicago's South Side. The students studied are five middle school boys who were observed over a two-year course of study under the same teacher who, after finding success with this method, found herself asking, how is it that underperforming readers were able to make their way into such complicated text? In fact, by the end of the two years, all were reading at or far above grade level. The study argues that focusing on students' strengths, teacher choice, and using the classics, introducing students to the best that literature has to offer, can provide a convincing case for the joys of reading—a far more convincing case that typical reading interventions provide.


This paper addresses the relationship between technology framing and new organizational forms and cultural artifacts embedded in information infrastructures such as intranets. Intranets can be viewed as important carriers of culture of organizations. New, young, web-based organizations provide interesting cases for exploratory research in this respect.


In this letter we propose a convex approach to learning expressive scalar conditional distributions. The model denoted by Normalizing Flow Regression (NFR) is inspired by deep normalizing flow networks but is convex due to the use of a dictionary of pre-defined transformations. By defining a rich enough dictionary, NFR generalizes the Gaussian posterior associated with linear regression to an arbitrary conditional distribution. In the special case of piece wise linear dictionary, we also provide a closed form solution for the conditional mean. We demonstrate the advantages of NFR over competitors using synthetic data as well as real world data.


A 21-year-old Caucasian male presented with a short history of epigastric pain and weight loss. Physical examination revealed splenomegaly only. Renal biochemistry and full blood count were normal. There were minor elevations in liver enzymes. A contrast-enhanced abdominal CT scan identified splenomegaly with infarcts, and portal and splenic vein thrombosis without cavernoma formation (figs 1 and 2). A thrombophilia screen comprising anticardiolipin immunoglobulin G (IgG) and lupus anticoagulant, factor V Leiden and prothrombin gene mutation analysis, protein C and S quantification and screening for paroxysmal nocturnal haemoglobinuria was normal. Bone marrow architecture was normal, with a non-significant increase in megakaryocyte count. The BCR-ABL oncogene was absent.

Security is not the absence of danger but the presence of Technology. Vehicle robbery is trending upwards so, This proposed work aimed to design and develop a anti-theft system that involves Global Positioning System (GPS) and Global System for Mobile Communication (GSM) technology in order to provide vehicle security. At the implementation of this system, when the vehicle is found to be robbed, the client receives a alert message along with the current location of the vehicle. So as the client can interact with the system by sending a stop message in order to stop the vehicle. Our next objective is to provide automated toll collection system which intern aid to achieve efficacious time utilization and simultaneous prevents traffic caused due to long queue at toll plaza using Radio Frequency Identification (RFID) technology. There by theft vehicles can also be detected using the concept of online toll payment. According to the parking law in India if the rules are violated we observe Regional Transport Office(RTO) lifts and takes off illegally parked vehicles. In order to overcome this, have included the concept where client receives the alert message as well as the current location. Vehicle loses power while driving so the self powering system is included which is beneficial to run further application like AC, radio etc... using Piezo electric plates.


Plasma chamber apparatus and method for using a magnet system for plasma inside the chamber is prevented from reaching the vacuum pump. Exhaust channel between the chamber interior and the pump comprises at least one deflector produces a magnet, the turbulence in the flow of exhaust gases. Both turbulence generated by the magnetic field and the deflector will increase the proportion of recombination of charged particles in the gas, whereby enough to extinguish the downstream side of the plasma concentrations of magnets and the deflector of a charged particle reduced, whereby the plasma body within the chamber from reaching the exhaust pump. Plasma confining effect of the magnetic field, compared to the case that would be required to prevent plasma without magnetic field, wide, and / or allow the use of small discharge duct of the meander. Therefore, it is possible to entirely dependent on the bending of the exhaust channel as compared with the prior art designs to prevent plasma, to reduce the pressure drop across the entire exhaust channel. Alternatively, if the magnetic field is strong enough, without also requiring what deflector exhaust channel, in the magnetic field alone can plasma is prevented from reaching the vacuum pump.


In this paper, we revise the Media Richness Theory (MRT) to be better applicable for mobile services and present a framework for explaining channel limitations and capabilities for mobile services. This framework can beused for evaluating existing services and developing enhanced mobile services with a supply side perspective to the richness of the media used for a service and the level of data or information aggregation. This framework is then illustrated with four different mobile services, demonstrating the usefulness of the framework, for instance, in considering the selection of different user interfaces.

The performance potential of multistatic sonar operations has been investigated by several research institutes and proven in numerous international sea trials during the last years. The characteristics of multistatic sonar operation are the use of one or more spatially separated transmitters and receivers, the exchange of the contact or track information as well as the appropriate combination of all available data in order to optimize the detection performance. In this context, the Low Frequency Towed Active Sonar (LFTAS) from ATLAS Elektronik is described, which is well suitable for multistatic operations because of its high detection ranges. Multistatic scenarios may be realised in numerous variations, e.g. two or more LFTAS-systems may work together or a submarine sonar system may act as an additional receiver. Multistatic operation provides some well known advantages like enlarged detection areas and increased probability of detection. Submerged operating submarines even can use the active transmission of other cooperative or noncooperative operating platforms to get information of the underwater situation. The system configuration and some aspects of signal processing, communication and data fusion in multistatic operation are outlined.


PATIENTS who return from the tropics may present a great variety of clinical syndromes. They may present themselves as a pyrexia of unknown origin, requiring special investigations for such conditions as malaria or visceral leishmaniasis, or with the dysenteric syndrome, requiring sigmoidoscopy and search for entamoeba histolytica in scrapings from the bowel. There may be undue loss of weight when sprue may enter the picture, or there may be a typical distribution of phrenic nerve pain produced by a liver abscess. Then there are the great varieties of helminthic infestations. The patient with ankylostominosis may be profoundly anaemic, or he may have abdominal symptoms closely resembling those of duodenal ulcer. Cysti-cercosis must always be borne in mind in those who develop epilepsy; occasionally this condition may be caused by other infestations, such as cerebral schistosomiasis, especially in schistosoma japonicum infestations in people from the Far East. And so it is that tropical diseases can produce diverse symptoms and signs, from fever to sore tongue, abdominal tumours due to splenomegaly, general wasting, abdominal symptoms chiefly related to the large bowel, hematuria, and, more rarely, evidence of filarial infestation, such as lymph scrotum. Recognition of this wide variety of clinical evidence is important, for tropical infections can often be specifically diagnosed and specifically treated. It is not possible in this paper to consider more than a very few points in relation to tropical diseases as seen at home, and so I propose to deal with the commonest condition, that is, malaria. This disease alone may present most varied clinical conclitions, such as recurrent pyrexia, jaundice due to bilious remittent fever, or blackwater fever, coma, or mental symptoms due to cerebral involvement, or chronic ill health. In order to properly understand malaria as seen in the non-immune European, there are certainly fundamental facts first to be considered, for these are the basis of rational treatment with the various specific drugs, and especially paludrine. Malaria infection is acquired under natural conditions in one way only, namely, by the bite of an infective female anopheline mosquito, i.e., the mosquito must have sporozoites in its salivary glands. Can naturally-acquired malaria occur at home? It is possible, for the local species of anopheles, anopheles maculipennis is an efficient vector, but the odds are against it, for the mosquito is cold-blooded, and development of the malaria parasite in the mosquito is very sensitive to the atmospheric temperature. However, …


To analyze the influences of the moving loads to dynamic responses of connected joints of floating bridges,ribbon bridge and separated bridge were selected,bridges and boats modeled as rigid-bodies and connected joints modeled by elastic joints.Transfer matrix method was used to establish the transfer matrixes of bridges,and boats and connected joints were assembled to transfer equations for programs.The dynamic responses of the ribbon bridge and separated bridge were calculated under different load velocities and the rigidities of the connected joints,and the displacement curves and force curves of the two floating bridges were obtained.The results of the numerical simulation show that the displacement of the floating bridges and the force of the connected joints increase with the increasing velocities of the moving load and the decreasing rigidities of the connected joints.Load velocity should be limited and the rigidity of the connected joints should be enhanced to decrease the displacement and the force for the security of the floating bridge with the moving loads.


This article investigates the robust exponential stabilization of a class of switched positive systems with uncertainties by co‐designing controllers for subsystems and dwell time switching strategy. The uncertainties refer to interval uncertainties. One of the distinguishing features is that none of the forced individual subsystems is assumed to be stabilized. The other feature is that the stabilization for the unforced switched system can not be solvable by designing dwell time switching signal. First, for switched positive systems without uncertainties, a type of multiple time‐varying co‐positive Lyapunov functions is used, and the computable sufficient conditions on the state feedback controller for each subsystem are derived in the framework of dwell time strategy. Moreover, the exponential stabilization problem is solved by confining the lower and upper bounds of the dwell time, restricting the upper bound of derivative of considered Lyapunov function of the active subsystem, and decreasing the Lyapunov function values at successive switching instants of the overall switched system. Then, the results are extended to the robust exponential stabilization case for switched positive systems with uncertainties, and sufficient conditions are given in the same framework of the dwell time for that of the forced switched systems by further designing state feedback controllers. Finally, illustration examples are given to illustrate the effectiveness of the proposed methods.


The regioselectivity of hydrocyanation of a range of protected α- and β-hydroxyalkynes has been investigated and shown to be highly susceptible to steric effects. Some of the products from hydrocyanation of protected β-hydroxyalkynes have been converted into α-alkylidene γ- lactones.


At a time when colleges and universities are being forced by the war to "search and research" the basic assumptions under which they have been operating, when articles on the plight of the liberal arts appear in every journal of opinion, it is high time that the art museums, as sister educational institutions, should also take educational stock. Mark Van Doren attributes good intentions to all educators but notes that "few reflect upon their intentions."2 We in the art museum must not only reflect, but must make an effort to reformulate our purposes in relation to the cultural situation today. More specifically, we must scrutinize our practices in relation to our general purposes and to the expressed, or unexpressed needs of the public whom we serve. And we will do well to set these purposes and practices before other educators for their criticism.


Abstract This article examines the consequences on women of having been reared to imbibe psychic structures that support and enact patriarchy and patriarchal ways of being. For girls, this involves still being schooled to care for, look out for, nurture, and provide for the needs of others. Women become especially alert to fragility and insecurity and—in trying to help others—they may unconsciously seek recognition for their own often unmet needs. Being raised with a feminized mind and body can incline women to feel uneasy about their own desires, their bodies, and their sexuality. Social movements instigate social and psychological change. With #MeToo, the unfinished work of Second Wave Feminism now enters mainstream public discourse. In addition, men's complex relationship to mothers and internalized authority also affects their subjectivity, rendering them sometimes embattled, sometimes fighting for control, and sometimes experiencing fragility vis-à-vis women.


Overloading of axial force acted on working roll is the primary reason to cause the bearing damage. Taking the working roll of four-roll mill as research object,the elastic flattening function based on rolling is established in this paper.According to independent action principle of force under small deformation,the stress and strain are calculated by means of superposition method.Combining the equation of strip shape with the convexity control principle,the crossing angle between rolls and the axial force of work roll are worked out reversely.


Because of their autonomy, flexibility and efficiency, mobile agents have become a hot topic in the e-commerce field. Meanwhile, another distributed technology, the Common Object Request Broker Architecture (CORBA), has a reliable, scalable and standard distributed structure. CORBA can be accepted as a platform for e-commerce because e-commerce is actually an important distributed implementation. Therefore, the integration of mobile agents and CORBA has become a new field in the e-commerce world. In this paper, we provide a reliable and flexible e-commerce architecture, which absorbs the advantages of mobile agents and CORBA, and adopts some suitable implementations for security protocols and quality of service (QoS). The paper also introduces new viewpoints, such as QoS implementation through CORBA events and flexible choices of different security protocols through the interfaces of atomic operations.


This experiment tested the level of Physics content knowledge of various K9-K12 Physics students in a local Boston high school by having them implement a mechanical engineering design process to solve open-ended design problems. Using MIT's 2.009 and 2.72 Mechanical Engineering project-based classes as models for project planning, a fully hands-on collaborative project was developed whereby students designed, built, tested, and then raced model kit cars driven by compressed gas. Over the course of six weeks, students selected three design elements of their car to change and did detailed analysis to predict how these changes would affect the performance of their car. Major deliverables of the project included a group-kept design notebook that was turned in on a weekly basis as well as a final product brochure that highlighted the major areas of learning that the students experienced with the project. Results of the project were positive. The stock kit car ran anywhere from 20-25mph without modifications, but students achieved speeds of over 95mph by optimizing their design in ways dictated by the laws of physics. Yet, there can be disconnects between what a student produces in his or her work and their true understanding of what they have done. By examining the design notebooks as well as through weekly interactions with the students, it was clear that very few students exhibited true ownership of some very fundamental principles of Physics and mechanics. Yet, these same students tended to do very well in their MCAS (Massachusetts Comprehensive Assessment System) as well as in the framework of traditional classroom testing and assignments. Conclusions can be drawn from this thesis work that although students can demonstrate proficiency of bodies of scientific knowledge in the framework of written tests, their understanding of the material does not go deep enough to immediately apply this content knowledge to solve open-ended engineering problems. The good news is that these students aren't employees of an engineering firm who are expected to arrive with a well founded mastery of their field, instead they are students who are expected to grow and learn from failures. It is clear that hands-on projects like the one developed for this thesis work serve as irreplaceable learning opportunities where students can bridge the gap between textbook learning and the true physical implications of what they learn. Not only this, but they learn basic problem-solving, time, and team management skills that will serve them well regardless of the path they choose after graduation. Thesis Supervisor: David R. Wallace Title: Implementing the Mechanical Engineering Design Process in K9-K12 Classrooms Searching for Deep Understanding: Implementing a Mechanical Engineering Design Process in K9-K12 Physics Classrooms to Identify and Improve Levels of Physics Intuition and Content Knowledge Author John Williams A Very Special Thanks To... Before anything else, I would like to thank those who provided help in any way with this thesis work. Charles Duggan Charles has been a mentor to me in many ways. Not only did he open up his classroom to me for my certification practicum work to become a K12 teacher in Massachusetts, but he also provided invaluable help in the classroom when I couldn't be around. Charles was also the major inspiration for choosing this particular project for my thesis work, his belief and commitment to excellence in teaching as well as his unwavering efforts to implement a hands-on and relevant curriculum to his students is truly inspiring. Vince Ciarametaro Vince also opened up his classroom to me for the implementation of this project. His help and partnership proved to be invaluable, as I did not know his students at all until the day the project began. I can tell that Vince appreciates and excels at his work as a teacher, his open-mindedness and pursuit of a dynamic and engaging learning environment will lead him to great places. Thank you so much Vince, it was an absolute pleasure working with you. Professor David R. Wallace Professor Wallace provided a tangible framework for the design of this project. Many elements were modeled directly after his 2.009 Product Engineering class, which is perhaps one of the best practical learning experiences available to undergraduates in the Mechanical Engineering Department. It is abundantly clear that he has devoted himself to honing every detail and module of the class to provide a deep and long-lasting impact on his students. As a student of his class, I can affirm that I graduated feeling prepared and confident to enter the world as a productive and functional mechanical engineer. Thank you professor Wallace for all of your guidance and hard work. (and of course...) The students! I hope that you learned much and grew from the experience. It would be nice to know you had fun doing it too! In all honesty, I was absolutely blown away by your work ethic, company, and quality of your work. I wish you all the best in whatever it is you choose to do with your bright futures.


The roofing industry in the United States generates annual revenues in excess of $23 billion. This represents a significant annual investment in infrastructure maintenance cost and the opportunity cost of these resources can significantly detract from an owner's ability to invest in other areas. In addition, a failed or failing roof system represents a heightened opportunity for failure in the building envelope and inherently increases the risk of additional costs. Present roof asset management practice typically bases replacement decisions on fixed intervals, inspection results, maintenance issues, and, occasionally, failure risk. This paper develops a model for evaluating occupant costs and considering their impact in the roof management decision process through a total life-cycle cost (LCC) model that includes user/occupant cost model and correlates minimum total cost with improved intervention points in the asset deterioration cycle. The model is estimated from and applied to the extensive roof systems at Carnegie Mellon University in Pittsburgh, Pa. For these roofs, we find that the least cost roof service lives are roughly 30 years, but there can be considerable variation around this average for individual roofs.


Last few years in Bangladesh, the crime rate has increased rapidly. Hence it is an essential task to analyze and predict the crime so that the authority can minimize or prevent the crimes easily. In this situation, machine learning can perform a notable role to reveal the crime trends and patterns of Bangladesh. Here, various machine learning regression models i.e. linear regression, polynomial regression, and random forest regression are used to forecast the trends and patterns of crime in Bangladesh. Dataset used in this research is available for the public which is gathered from the Bangladesh police's website. The dataset comprises record about various crime types i.e. dacoity, robbery, kidnapping, murder, women & child repression, theft, burglary, arms act, explosive, narcotics, and smuggling of Bangladesh. Firstly, training of regression models is done on the training dataset. After completion of the training, forecasting of crime is performed on the test data by the different regression models. Then we compare the forecasting results with the actual results and calculate the model evaluation metrics for the different applied regression models. After comparing the result, it is possible to find out the best-suited regression model for the crime-related data among all the applied regression models. Finally, it is observed that polynomial and random forest regression are better to predict the crime trends and patterns than the linear regression.


We present a (2+1)-dimensional partial differential equation model for spatial-lateral dynamics of edge-emitting broad-area semiconductor devices and several extensions of this model describing different physical effects. MPI-based parallelization of the resulting middlesize numerical problem is implemented and tested on the blade cluster and separate multi-core computers at the Weierstrass Institute in Berlin. It was found, that an application of 25-30 parallel processes on all considered platforms was guaranteeing a nearly optimal performance of the algorithm with the speedup around 20-25 and the efficiency of 0.7-0.8. It was also shown, that a simultaneous usage of several in-house available multi-core computers allows a further increase of the speedup without a significant loss of the efficiency. Finally, an importance of the considered problem and the efficient numerical simulations of this problem were illustrated by a few examples occurring in real world applications.


Interview with ECA-USP professor (already retired) Mario Fanucchi, television and radio professional, in which he talks about the experience of having lived the day-to-day challenges in the media, most especially during TV's inaugural period. At TV Tupi Fanucchi was responsible for creating inter-programs - forerunners of the current commercials he coordinated the programming of the first years of the TV Cultura, and was also among those responsible for the new Radio USP project.


Aim: To assess the causes, frequency and time of conversion from laparoscopic to classic cholecystectomy in our own material. Material and methods: 547 patients were qualified for laparoscopic cholecystectomy in the Surgery Department of the Mogilno District Hospital in Strzelno during the period of 1999-2005; 515 minimally invasive operations were performed and 32 patients required conversion. Results: The 547 patients were qualified for the laparoscopic operation; of these 148 were operated on as emergency cases and 399 as elective cases. There were 20 conversions among emergency patients and 12 conversions among elective patients. On average the decision to convert was made in the 35th min of the operation. The shortest time to conversion was 15 min and the longest was 90 min. Five conversions were performed in the 25th and 35th min and 4 in the 20th, 30th, and 40th mine. Most frequently conversions occurred between the 20th and 40th min of the procedure. Intentional conversions were performed in 27 patients. Adhesions and clumps around the gallbladder were the cause of conversion in 10 patients and that was the most frequent reason for the operative modality change. The next cause of conversion was changes observed in the course of acute cholecystitis in the form of gallbladder empyema or cholecystocele (9 patients). Small, fibrotic gallbladder, immersed in the liver, was the reason for conversion in a further 4 patients. In 4 cases the conversion was caused by difficulties in the identification of anatomical structures. Four cases of forced conversions and 1 anticipated conversion were found in the analysed material. Conclusions: A change of operative modality during laparoscopic cholecystectomy was made on average in 5.85% of operations. The average time before the conversion was 35 min. Emergency patients required a change of operative modality 4 times more often. The most frequent were intentional conversions (84%), caused by pericystic adhesions and by inflammatory changes impeding the identification of anatomical structures. The predominant cause of forced conversions was intra-operative haemorrhage.


The scan and frequency dependent aperture surface impedance is a useful way to study the effects of the active phased array. The surface impedance of an ideal current sheet diverges for orthogonal E- and H-plane polarizations at large scan angles, based on fundamentals. This phenomenon can be reproduced in the phased array unit cell using modern Finite Element Modeling techniques. It can also be corrected within a limited frequency range using complex conjugate matching schemes, which are also termed Wide Angle Impedance Matching (WAIM) techniques. While these latter techniques often introduce surface wave resonance effects, a parasitic element approach satisfies the complex conjugate condition with minimal surface wave effects. This last approach includes the geometry found in a stacked patch radiator.


In order to reduce the degradation caused by, LID effect of the conversion efficiency of photovoltaic cells made of crystalline silicon, at least one step for introducing controlling air gap to the silicon in to, silica siding, knitted riding, ion implantation, laser irradiation, mechanical bending stress with the temperature that promotes the formation of pores of the substrate, is carried out by a step selected from among one or more steps to be applied on one surface of the silicon substrate. These pores are enabled for by the effect of the diffusion of oxygen and the VO complexes precipitated, reduce the level of interstitial oxygen. The introduction of pores has a different effect of reducing the level of auto-interstitial, and thus limit the formation of the interstitial boron. Therefore, there is a limit to the symptoms of the LID by activation of B The invention is applicable to photovoltaic cells, based on the monocrystalline or polycrystalline silicon having a high concentration of boron and oxygen in particular.


Digital technology is fast changing in the recent years and with this change, the number of data systems, sources, and formats has also increased exponentially. So the process of extracting data from these multiple source systems and transforming it to suit for various analytics processes is gaining importance at an alarming rate. In order to handle Big Data, the process of transformation is quite challenging, as data generation is a continuous process. In this paper, we extract data from various heterogeneous sources from the web and try to transform it into a form which is vastly used in data warehousing so that it caters to the analytical needs of the machine learning community.


Objective: To determine the effect of whole body vibration on isometric and eccentric torque and electromyography (EMG) variables of knee extensors on the affected side of stroke patients. Design: A randomized controlled study. Setting: A rehabilitation centre. Subjects: Sixteen patients (age 58.2 ± 9.4 years) were enrolled in an inpatient rehabilitation programme 27.2 ± 10.4 days after a stroke. Interventions: Eight patients were randomly assigned to the vibration group and received 20 Hz vibration (5 mm amplitude) while standing on a vibration platform for 1 minute six times in one session. Patients in the control group also stood on the platform but did not receive vibration. Main measures: Maximum isometric and eccentric torque, rate of torque development, root-mean-squared EMG, median frequency of vastus lateralis, and co-activation of knee flexors. Results: Isometric and eccentric knee extension torque increased 36.6% and 22.2%, respectively, after vibration (P < 0.05) and 8.4% and 5.3% in the control group. Vibration increased EMG amplitude 44.9% and the median frequency in the vastus lateralis by 13.1% (all P < 0.05) without changes in the control group (10.6% and 3.9%). Vibration improved the ability to generate mechanical work during eccentric contraction (17.5%). Vibration reduced biceps femoris co-activation during isometric (8.4%, ns) and eccentric (22.5%, P < 0.05) contraction. Conclusion: These results suggest that one bout of whole body vibration can transiently increase voluntary force and muscle activation of the quadriceps muscle affected by a stroke.


The concept of 3D freehand ultrasound has been of great interest to researchers for decades due to many advantages over conventional 2D ultrasound, such as image quality that is less dependent on a sonographer's skills and more intuitive and interactive 3D views of scanned objects. However, obstacles such as the need for spatial calibration remain, which hinder the effective application of this technique in clinical settings. Here we report the feasibility and accuracy of performing spatial calibration based upon a closed-form solution to matrix equations formed by two independent general motions. We achieved millimeter-level accuracy for translational and degree-level accuracy for rotational degrees of freedom. The calibration accuracy may be further improved by optimizing the matrix solution.


Surface flux estimation is essential to land surface modeling in earth system models. In practice, parameterizations of surface turbulent fluxes are almost all based on the similarity theory. That is, the grid or subgrid mean surface‐layer flow is assumed at equilibrium with the underlying earth surface, and therefore some empirical relations can be used to estimate surface fluxes. In this paper, scale‐dependent estimability of turbulent flux in the unstable surface layer is systematically investigated based on high‐resolution large‐eddy simulation data over a flat and homogeneous domain, representing a typical land surface modeling grid. It is found that turbulent flow in the unstable surface layer inherently fluctuates over a wide range of scales. This kind of fluctuation affects the steady‐state relations between mean atmospheric quantities and underlying earth surface, and hence affects the estimability of surface fluxes. Sensitivity tests show that the relative root mean square error of the estimated surface friction velocity for a subdomain generally increases as the subdomain becomes smaller. The error can be as high as 35% as the subdomain size decreases to the order of the surface layer height. To achieve an error of 10% for all cases, the subdomain size should be at least on the order of the boundary layer height. These findings imply that estimability‐based strategies may be needed for representing subgrid heterogeneity for surface flux estimation in land surface modeling.


The gross composition of normal squirrel monkey milk was (in g/l00 ml): lipids, 5.1; crude protein (N × 6.38), 3.5; lactose, 6.3; and ash, 0.3. The lipids, proteins, and ash were further characterized. This milk had many similarities to milk from other primates, and was intermediate in total protein and lactose concentration between milks from Old World monkeys and prosimians.


Using additional boundary conditions (ABC) and an additional sought function (ASF), a solution to the heat conduction problem with non-homogeneous boundary conditions has been obtained. ABC allows satisfying the differential equation at the boundaries, leading to its fulfillment both inside the domain and without resorting to integration over Cartesian coordinates. ASF reduces the original partial differential equation to a temporal ordinary equation, from which the eigenvalues of the boundary value problem are determined, as formulated in the classical methods of the Sturm-Liouville problem, stated in spatial variables. Thus, this work considers an alternative way of determining eigenvalues. The integration constants are found from the initial condition using the least squares method, which allows their values to be determined with a given accuracy. The solution obtained based on ABC and ASF approximates n → ∞ the exact analytical solution in the form of an infinite series, including trigonometric coordinate functions with coefficients that stabilize exponentially in time. In this case, the eigenvalues determined from the solution of the temporal ordinary differential equation regarding the additional sought function coincide with their exact values at any approximation. The accuracy of the integration constants, determined by the method of least squares, is controlled by the number of approximation points in the range of the auxiliary variable's variation. It should be noted that the additional boundary conditions considered in this work hold true for any other method of obtaining a solution to the problem under consideration, including the exact method, as can be verified by direct substitution. Therefore, their introduction does not distort the original mathematical formulation of the problem but only significantly simplifies the process of obtaining its analytical solution.

THE RELATIONSHIP OF MENTAL OR EMOTIONAL PROBLEMS IN THE FAMILY-OF-ORIGIN ON MARITAL SATISFACTION OF ADULT OFFSPRING Benjamin O. Weinheimer Marriage and Family Therapy Program School of Family Life Master of Science The effects of perceived mental/emotional problems (psychopathology) in the family-of-origin on adult offspring marital satisfaction was tested in a model considering the mediating variables of parental marital satisfaction, mother-child relationship quality, father-child relationship quality, and resolution of issues from the family-of-origin. The nationally representative sample (n = 802) drawn from the RELATionship Evaluation (RELATE) database included mostly college educated, lower-middle-class individuals in their first marriage. This sample was used to test a structural equation model that results showed fit the data well. Results showed that historical (distal) factors (such as psychopathology in the family-of-origin) explain only a small portion of the variance in adult offspring marital satisfaction and suggest that more contemporary (proximal) factors (such as individual characteristics) have a stronger relationship to adult offspring marital satisfaction. Results showed that 56% of the variance in achieving resolution of issues from the

The retrospective study showed that 87.4%(248/279) ovarian poor responder could be reversed by reduced the dose of GnRH-a or increased initial Gn dose compared with full or a half dose and one third dose of GnRH-a down-regulation groups,only 11.1%(31/279) cases taken place ovarian poor responder again in next IVF-ET cycle.The result implied that profound ovarian suppression could be reversed by reduced GnRH-a dose or increased Gn dose in women with ovarian normal function.The dose of GnRH-a may have an impact on the steroidgenesis in IVF-ET cycles.


To determine the prevalence, species, and antibiotic sensitivities of anaerobic bacterial infections in reptiles, the results of bacterial cultures from clinical cases presented to the University of California Veterinary Medical Teaching Hospital were reviewed. During the 2-yr study period, 65 specimens were submitted for both aerobic and anaerobic bacterial isolation. Sample collection sites included subcutaneous and internal abscesses, lungs, and the coelomic cavity. Of the 39 specimens yielding bacterial growth, 21 (54%) included anaerobic bacteria and produced 35 isolates of the genera Bacteroides, Fusobacterium, Clostridium, and Peptostreptococcus. The 19 isolates tested in vitro were least sensitive to penicillin (80%) and most sensitive to metronidazole (100%). Ami noglycosides are currently among the most commonly used antibiotics in reptile medicine but have no efficacy against anaerobic bacteria. The prevalence of anaerobic bacterial infections found in this study suggests that the use of aminoglycoside antibiotics alone may be inappropriate for the treatment of infectious diseases in reptiles.


Cochin and Kornetsky (1) showed that tolerance to the effects of a single injection of morphine in the rat as measured by the hot plate reaction could be demonstrated for periods up to one year following that single injection. Thus, they postulated that tolerance to narcotic drugs might well be an immune phenomenon or a mechanism resembling the antigen-antibody reaction. Later, Kornetsky and Kiplinger (2, 3) attempted a passive transfer of a hypothetical factor of tolerance in serum from morphine-tolerant animals (rat, dog, monkey and man) to nontolerant animals (mouse). Although they were unsuccessful in transferring the tolerance, they succeeded in demonstrating the presence of certain transferable factors in the serum of morphine-tolerant animals, since under condition of those studies, potentiation of the depressant and an analgesic action of morphine was observed. The role of the potentiating substance in the serum of the morphine-tolerant animal and the mechanism by which it potentiates morphine are as yet unknown. On the other hand, Kornetsky and Cochin (4) reported that serum from morphinetolerant rabbits attenuated morphine analgesia in mice and they assumed that the immune mechanisms involved may partially account for some of the phenomena associated with tolerance to morphine. Ungar and Cohen (5) also showed that administration of extracts of the brain taken from morphine-tolerant rats and dogs conferred tolerance on mice. The presence of the factors in the blood of morphine-tolerant animals that have attenuating or enhancing effects on morphine in nontolerant animals is an interesting finding, although the immune reaction hypothesis is no more than speculation. During a study of the effect of the treatment with a homogenate of the brain from alcohol-tolerant rabbits, on the duration of alcohol anesthesia following the intravenous injection of a test dose of alcohol, it was noted that an increased sensitivity and/or a decreased or a biphasic change in the sensitivity to alcohol was observed depending on the individual rabbit. Based on these conflicting evidences the present investigation was undertaken to define the change of sensitivity to alcohol using the normal rabbit as the recipient and the donor species.


All active geological processes determine effects on the soil due to different deformation processes: surface uplift and subsidence, shear lineaments with differential kinematics in relation to the source and the soils involved. Nowadays the remote sensing represents a key tool for the evaluation and monitoring of the natural hazards. The use of Unmanned Aerial Vehicles (UAVs) in contexts of natural hazard presents three main steps for risk assessment and monitoring: pre-post event data acquisition, emergency support and monitoring. The mud volcano of Santa Barbara (Municipality of Caltanissetta, 15 Italy), represents a dangerous site because on 11th August 2008 a paroxysmal event caused serious damage to infrastructures for a range of about 2 km. The main clues of mud volcano paroxysmal events are the uplift and the development of structural features with dimensions ranged from centimetre to decimetre. Here we present a methodology for monitoring of deformation processes that may be precursors of paroxysmal events on the Santa Barbara mud volcano. This methodology is based on i) the data collection, ii) the Structure forom Motion (SfM) processing chain and iii) the M3C2-PM algorithm for 20 the comparison between point clouds and uncertainty analysis with a statistical approach. The objective of this methodology is to detect hazard precursors by monitoring of deformation processes with centimetre precision and a temporal frequency of 1 2 months.

The seasonal and interannual variation in the lower mesospheric subtropical jet (LMSJ) and their dependence on the 11‐year solar cycle are studied by comparing observational data with simulations by two general circulation models. In the model simulations, a strengthening of the LMSJs is found in both hemispheres during the winter under the solar maximum condition, similar to the observation. However the model responses are substantially smaller except for one case in the southern hemisphere. It is also found that the stronger LMSJ due to an enhanced solar forcing appears during the period which follows an increasing period of interannual variation. Analysis of the observed seasonal march of the LMSJ in each year shows two different regimes of behavior. For a successful simulation, the model should realistically reproduce the observed interannual variability as well as the climatological mean.


Cable structures are lightweighted, simple to fabricate and reusable. They provide effective solutions for large-span structures. Analysis of cables is complex because of their highly geometrically nonlinear behavior. Based on the Lagrangian formulation and a fourth-order polynomial displacement function, the tangent stiffness matrix for a five-node curved cable element is derived and statically condensed to a simple form readily for incorporation into a frame analysis computer program. The program uses the pointwise–equilibrium–polynomial (PEP) element with initial imperfection and the "Nonlinear Integrated Design and Analysis (NIDA)" method for design and nonlinear analysis of cabled structures. Numerical examples demonstrate the robustness and practicality of the proposed method.


The circulation in two water column thickness scenarios for Lake Vostok, a subglacial lake in central East Antarctica, is investigated using a three‐dimensional numerical model. In a scenario with a constant water column thickness (the distance between the sloping ice sheet which caps the lake and the lake bed) the circulation is barotropic, but with a more realistic water column thickness the flow is baroclinic. The different circulations result from the geothermal heat flux warming shallow regions of the realistic lake more efficiently, thus forming a different horizontal density structure. The differences and uncertainties between the two scenarios highlight the importance that the largely unknown water column thickness and geothermal heat flux have in determining the circulation in the lake.

The cluster analysis ofagricultural enterprises is made by region  Ukraine. The analysis is made by the agricultural sector and its subsectors: plant-growing and animal husbandry. Homogenous regional zones characterizing the performance  agricultural enterprises are identified. The clustering is made using SPPS software. In the problems involved in the cluster analysis Euclidean distance is used. The cluster analysis is used for constructing green maps illustrating the impact  agricultural activities at enterprises on the production output of the agricultural sector and its subsectors: plant-growing and animal husbandry. The constructed dendrogram was used fo r creating two clusters showing low and high performance of the plant-growing sector. The first cluster includes 17 regions  Ukraine have high performance along with low application  mineral fertilizers: Vinnytsya region, Dnipropetrovsk region, Donetsk region, Zhytomyr region, Zaporizhzhya region, Kyiv region, Kirovohrad region, Luhansk region, Mykolaiv region, Odesa region, Poltava region, Sumy region, Kharkiv region, Kherson region, Khmelnytsk region, Cherkasy region, andChernihiv region. The second cluster includes 7 regions with low plant-growing performance along with intensive application  mineral fertilizers: Volyn region, Transkarpaty region, Ivano- Frankivsk region, Lviv region, Rivne region, Ternopil region, Chernivtsi region. The characteristics of regional zones by agricultural production output, numbers  cattle and poultry, and agriculture performance give evidence that in view ofthe similarity in the conditions  their territories, they require similar measures aiming to improve business environment in the sector and mechanisms fo r the development  agroindustrial complex in Ukraine.


The present study was carried out to investigate the comparative effect of antonym in-text glosses and description in-text glosses on a group of Iranian EFL learners' reading comprehension. To fulfill the purpose of this study, 60 female intermediate students between 18 and 19 years old were selected among a total number of 90 through their performance on a piloted PET. These 60 participants were non-randomly divided into two equally populated experimental groups. During the process of this study, in one of the experimental groups the participants were given reading texts with antonym in-text glosses and in the other group, the participants were given reading texts with description in-text glosses. A piloted reading comprehension posttest (derived from another sample of PET) was administered at the end of the treatment to both groups and their mean scores on the test were compared through an independent samples t-test. The result led to the rejection of the null hypothesis, thereby, demonstrating that the learners in the description in-text glosses group benefited significantly more than those in the antonym in-text glosses group in terms of improving their reading comprehension.


Background/Objective: Mobile frameworks for automobiles, trains, airplanes, and buses that use roaming networks as a unit are based on internet transparency. For implementation of the framework, the Network Mobility Basic Support (NEMO BS) protocol was proposed and developed by the Internet Engineering Task Force. Although NEMO BS performs continuous, optimized, and safe communications for all nodes, it has a handoff delay and packet transmission delay a tan increasing nested level. Method/Statistical Analysis: To solve the problems, this study makes use of a hierarchical structure in an advanced binding update list, and proposes a new route optimization method for nested mobile networks. Findings: The proposed method is aimed at solving the problem of pinball routing and at making handoffs smooth. The method proposed in this study minimizes transmission delay, handoff delay, and packet overhead, and solves the problems of NEMO BS for optimized routing in nested mobile networks. The proposed method shows performance three times higher than NEMO BS, and 88% higher than the ROTIO. This study's results prove that the proposed method offers more improved performance than NEMO BS and ROTIO with a rise in nesting level. Improvements/Applications: According to the performance evaluation, the proposed method reduces packet overhead, handoff delay, and packet transmission delay, and performs optimal routing.

Purpose Hypoxia-mediated neurotoxicity contributes to various neurodegenerative disorders, including Alzheimer disease. Neuregulin-1 (NRG1) plays an important role in the development and plasticity of the brain. The aim of the present study was to investigate the neuroprotective effect and the regulating hypoxic inducible factor of NRG1 in cobalt chloride (CoCl2) induced hypoxia. Methods Hypoxia was induced in SH-SY5Y cells by CoCl2 treatment. SH-SY5Y cells were pretreated with NRG1 and then treated with CoCl2. Western blotting, immunocytochemistry, and lactate dehydrogenase (LDH) release assays were performed to examine neuroprotective properties of NRG1 in SH-SY5Y cells. Results Our data showed that CoCl2 induced cytotoxicity and changes of hypoxia-inducible factor-1α (HIF-1α) and p53 expression in SH-SY5Y cells. However, pretreatment with NRG1 inhibited CoCl2-induced accumulation of HIF-1α and p53 stability. In addition, NRG1 significantly attenuated cell death of SH-SY5Y induced by CoCl2. Conclusions NRG1 can regulate HIF-1α and p53 to protect neurons against hypoxic damage.


As this informative essay by Stephanie Fitzgerald and Hilary E. Wyss makes clear, Native American literatures and textualities have, like Native tribal nations, long been plural, multilingual, grounded in home places, deeply invested in land, and shared across networks of relations. Native people have for centuries been literate in earthworks, baskets, trade routes, petroglyphs, ecosystems, rhetorical performances, newspapers, treaties, books, and many other kinds of legible texts that they have created as well as, in some instances, received; Native knowledge has for centuries traversed space as well as time. Contemporary Native writers such as LeAnne Howe (Choctaw), Simon Ortiz (Acoma), and Louise Erdrich (Anishinaabe) detail the ways in which the multiple archives of the past—early and recent, oral and written, accessible and inaccessible—inform and challenge the present. Storytellers such as the western Apache in Keith Basso's landmark study Wisdom Sits in Places (1996) know that "the country of the past . . . is never more than a narrated place-world away. It is thus very near, as near as the workings of their own imaginations, and can be easily brought to life at almost any time" (32). From Abenaki space on the other side of the continent, Lisa Brooks expresses a similar perception in the opening sentence of her important book The Common Pot: The Recovery of Native Space in the Northeast (2008), writing that she and her friend Natalie "are sitting on the grass, stretching our legs, beside this old

Recently Professor Chandrashekar Adiga et al (3) defined the minimum covering energy, EC(G) of a graph which depends on its particular minimum cover C. Motivated by this, we introduced minimum dominating energy of a graph ED(G) and computed minimum dominating energies of a star graph, complete graph, crown graph and cocktail graphs. Upper and lower bounds for ED(G) are established.


Sparse sensors that recognize full-body human motion and that control the motion of virtual humans have emerged as valuable research tools in the field of human–computer interactions. Here we propose a method for motion recognition and prolonged, continuous generation of motion data based on the recognition results. The only inputs required are the directional accelerations collected by four Wii remotes, which are attached on the four limbs of a human. The extended and continuous signal sequences are separated into small segments that can be described by particular motion content. Use of a fused hidden Markov model (FHMM) during the recognition process ensures the accuracy and efficiency with which independent motion segments are recognized. A graph model enhances the capacity of classification when dealing with a signal sequence associated with a prolonged motion. During the reconstruction and generation processes, an efficient state-based motion graph generates the extended and continuous virtual human motion data, which accurately reflects variation in the movement of the actors. Our method has a strong capacity to classify types of motion upon their recognition and the control process can be applied to a range of applications involving interaction.


A novel very-low-bit-rate textured image compression scheme is proposed in this scheme, both texture self-similarity property and affine transform are used as basis to achieve coding tasks. An input texture image can be reconstructed from both the prototype block spectral and the corresponding affine transform parameters. These parameters are estimated from the prototype block spectral and that of the rest blocks using the multiresolution Fourier transform, MFT, of the input image. In the synthesizing process, two different groups of parameters are generated, the MFT coefficients of the prototype block and the estimated affine parameters amongst blocks. In order to achieve the very-low-bit-rate coding scheme, this paper presents the quantization and coding scheme of the transformed coefficients and the estimated affine parameters. Consequently, figures of the compression and distortion ratio of the reconstructed image can be measured to analyze the structure of textured image over various scales.

Foraminiferal tests are commonly found in tsunami deposits and provide evidence of transport of sea floor sediments, sometimes from source areas more than 100 m deep and several kilometers away. These data contribute to estimates of the physical properties of tsunami waves, such as their amplitude and period. The tractive force of tsunami waves is inversely proportional to the water depth at sediment source areas, whereas the horizontal sediment transport distance by tsunami waves is proportional to the wave period and amplitude. We derived formulas for the amplitudes and periods of tsunami waves as functions of water depth at the sediment source area and sediment transport distance based on foraminiferal assemblages in tsunami deposits. We applied these formulas to derive wave amplitudes and periods from data on tsunami deposits in previous studies. For some examples, estimated wave parameters were reasonable matches for the actual tsunamis, although other cases had improbably large values. Such inconsistencies probably reflect: (i) local amplification of tsunami waves by submarine topography, such as submarine canyons; and (ii) errors in estimated water depth at the sediment source area and sediment transport distance, which mainly derive from insufficient identification of foraminiferal tests.


Recognizing road shape is one of the fundamental functions for outdoor navigation of mobile robots and vehicles. This function is crucial for safe control and used for autonomous navigation combined with global localization using maps or GNSS. This paper describes a method of estimating the 3D structure of road boundaries using a 3D LiDAR with a combination of scanline-wise 1D feature extraction and temporal filtering by particle filter. In outdoor environments, since the road shape changes not on a horizontal plane but three-dimensionally, we model the road boundary shape with a series of 3D segments and estimate its parameters repeatedly with the feature extraction and particle filter. The proposed method is tested in terms of the feature extraction performance and the applicability of autonomous navigation.


In this work a coupled two‐scale beam model using Timoshenko beam elements [1] with finite displacements on the macro scale and fully non‐linear 3D brick elements on the micro scale is proposed.

Objective The present study aims to probe into the feasibility and safety of larger balloons in the self-expandable stent Wingspan system when treating symptomatic intracranial arterial stenosis.Methods The clinical data of 109 symptomatic intracranial arterial stenosis patients,consisting of 68 males and 41 females,were analyzed.These patients were treated via angioplasty using the Wingspan system from March 2007 to June 2010.The ages of the patients ranged from 36 years to 79 years,with an average of 62.4.The patients were divided into two groups according to the sizes of the Gateway balloons they used.The balloon diameter for group A(n=31) was based on 80% of the diameter of the normal blood vessels on both sides of the arterial vessel.Meanwhile,the balloon diameter for group B was based on the average diameter of the vessels on both sides of the arterial vessel.The effects of the treatment and the occurrence of complications in both groups were analyzed and compared.Results The degree of arteriostenosis before operation for group A was 56.0% to 87.8%,with an average of 71.8%,residual stenosis after operation was 0% to 45%,with an average of 24.9%.The degree of ateriostenosis before operation for group B was 68.9% to 98.0%,with an average of 76.0%,residual stenosis after operation was 0% to 21%,with an average of 10.2%.Group A had four cases(12.9%) of durability neurological dysfunction.One case was a visual-field defect.In group B,six patients(7.7%) experienced complications.The differences were not statistically significant,and no deaths occurred in both groups.Conclusions Wingspan stent angioplasty is a safe and effective treatment for intracranial arterial stenosis,and even the use of larger balloons does not increase the risk in patients.


The DC network security constraints have been extensively studied in numerous power system problems, such as optimal power flow (OPF), security-constrained economic dispatch (SCED), and security-constrained unit commitment (SCUC). Linear shift factors, i.e., power transfer distribution factors (PTDFs), are widely applied to replace DC power flow constraints. However, the PTDF matrix is extremely dense, making it difficult to solve security-constraint optimization problems. This paper analyzes/investigates the computational inefficiency of PTDF-based security constraints from the sparse structure perspective of the primal-dual interior point method(IPM). Additionally, a matrix transformation method is proposed for restoring the sparsity of the linear system during IPM iterations. It turns out that the transformation method is equivalent to solving the original optimization problem expressed in pure voltage angle, which preserves the sparsity structure but introduces additional variables and constraints proportional to one to two times the total number of buses. The regular B-$\theta$ formulation is also a variant of the proposed transformation. Numerical studies show that sparsity rather than the size of variables and constraints is the key factor impacting the speed of solving convex quadratic problems (QP), i.e., OPF and SCED problems. In contrast, sparsity is less desirable when solving a mixed integer problem (MIP), such as the SCUC problem, where reoptimization techniques are significantly more critical and the dual simplex method is typically employed rather than IPM.

Serum alkaline phosphatase, gamma glutamyl transferase, alanine and aspartate amino transferases were estimated in viral hepatitis, alcoholic liver diseases, obstructive jaundice, cirrhosis of the liver. These enzymatic variations are useful to diagnose the disease and classify them according to etiology.


Synthesis of multiple stable isotope-labeled antibacterial agent RWJ-416457, (N-{3-[3-fluoro-4-(2-methyl-2,6-dihydro-4H-pyrrolo[3,4-c]pyrazol-5-yl)-phenyl]-2-oxo-oxazolidin-5-ylmethyl}-acetamide), and its major metabolite, N-{3-[4-(2,6-dihydro-4H-pyrrolo[3,4-c]pyrazol-5-yl)-3-fluoro-phenyl]-2-oxo-oxazolidin-5-ylmethyl}-acetamide, is described. The stable isotope-labeled [13CD3]RWJ-416457 was prepared readily by acetylation of the precursor amine, 5-aminomethyl-3-[3-fluoro-4-(2-methyl-2,6-dihydro-4H-pyrrolo[3,4-c]pyrazol-5-yl)-phenyl]-oxazolidin-2-one with CD313COCl in pyridine. Synthesis of the stable isotope-labeled metabolite involved a construction of multiple isotope-labeled pyrazole ring. N,N-dimethyl(formyl-13C,D)amide dimethyl acetal was first prepared by treating N,N-dimethyl(formyl-13C,D)amide with dimethyl sulfate, followed by sodium methoxide. Then, N-{3-[3-fluoro-4-(3-oxo-pyrrolidin-1-yl)-phenyl]-2-oxo-oxazolidin-5-ylmethyl}-acetamide was condensed with N,N-dimethyl(formyl-13C,D)amide dimethyl acetal, and the resultant β-ketoenamine intermediate underwent pyrazole ring formation with hydrazine-15N2, to give the [13C15N2D]-labeled metabolite.

We examined the effects of transition from military rule to democratic rule and ethnic diversity on households' access to safe drinking water and electricity in Nigeria. A combination of probit regression and panel analysis show that democracy at the sub-national levels has not improve provision of safe drinking water and electricity in the country. Our results show that executive competition reduced access to the two public goods ten years into democratic rule in the country. This we argue is due to the problem of political capture by special interest groups at the sub-national level, due to the lack of credible electoral system in the country. Legislative competitions on the other hand have positive effects on the provision of safe drinking water and electricity under democratic rule. Ethnic diversity at the sub-national level has reduced household's access to safe drinking water but increased provision of electricity from our analysis. The implication of our finding is that provisions of targeted public goods are prone to negative effects of ethnic diversity at the sub-national level than non-targeted public goods. We therefore recommend that the national government should provide targeted public goods if sub-national governments are ethnically heterogeneous to prevent the negative effects of ethnic diversity. When provision of public goods cannot be targeted, ethnic diversity at any level of government cannot affect provision of such public goods irrespective of the level of government responsible for its provision. Our finding is significant especially in many ethnically heterogeneous developing countries currently experimenting with democracy at various tiers of governments.

The widespread adoption of Internet of Things has led to many security issues. Post the Mirai-based DDoS attack in 2016 which compromised IoT devices, a host of new malware using Mirai's leaked source code and targeting IoT devices have cropped up, e.g. Satori, Reaper, Amnesia, Masuta etc. These malware exploit software vulnerabilities to infect IoT devices instead of open TELNET ports (like Mirai) making them more difficult to block using existing solutions such as firewalls. In this research, we present EDIMA, a distributed modular solution which can be used towards the detection of IoT malware network activity in large-scale networks (e.g. ISP, enterprise networks) during the scanning/infecting phase rather than during an attack. EDIMA employs machine learning algorithms for edge devices' traffic classification, a packet traffic feature vector database, a policy module and an optional packet sub-sampling module. We evaluate the classification performance of EDIMA through testbed experiments and present the results obtained.

Abstract Just as buying and selling over the Internet represents a new frontier for commerce, teaching students how tobest use the Internet in marketing presents educators with new challenges and new opportunities. Perhaps themost distinguishing feature of Internet commerce that must be confronted by educators is the general absenceof inter-personal communication in customer exchanges. As most Internet marketing takes place using a self-service technology (SST) that enables customers to consume products independent of direct serviceemployee involvement (Meuter, Ostrom, Roundtree and Bitner 2000), it seems inappropriate to teachmarketing in an Internet environment by relying on traditional lecture-tutorial methods, even with theaugmentation of a supporting website that offers chat rooms, teaching materials and other resources offered byelectronic learning systems such as WebCT and Blackboard. This paper describes the use of an online role-play designed to provide students with experiential learning by using Internet technologies. The findings ofthis study suggest that incorporating an online role-play component enables students to apply theoreticalapplications in 'real world' situations.


A trireflector antenna configuration is presented that allows for beam scanning with minimum reflector motion, no feed motion, and high primary aperture utilization for all scan directions. Such characteristics are particularly desirable for geostationary satellite applications. Omnidirectional beam scanning is achieved by rotational movement of a relatively small tertiary reflector about a fixed point such that a simple two-axis gimbal can be employed. The trireflector configuration was specifically designed for high-gain passive remote sensing applications, and therefore the emphasis is placed on high-gain beam scanning; however, the concepts developed are equally valid for low-gain applications and can find use in a broad range of applications that require rapid beam scanning and simple reflector motion. >

The system design based on ARM core microprocessor and FPGA programmable logic chip containing some memory units and periphery component has realized the automatic zero compensation and data acquisition as well as PC video displaying. Consequently,the volume of the hardware is smaller; power consumption is lower; the functions are mightier and the expansibility is stronger.


A low inductance three‐electrode spark source for the vacuum ultraviolet fed by a 20‐kV, 13‐μF capacitor is described. Its main feature is its ability to generate spectra of very high degrees of ionization. A 6‐kV spark produces spectra of CV and CVI as well as FeXVI, while a 17–18‐kV spark yields FeXVIII, AlXII, and AlXIII.


Observed avalanche flows of dense granular material have the property to present two possible behaviors: static (solid) or flowing (fluid). In such situation, an important challenge is to describe mathematically the evolution of the physical interface between the two phases. In this work we derive a set of equations that is able to manage the dynamics of such interface, in the so-called shallow regime where the flow is supposed to be thin compared to its downslope extension. It is obtained via a shallow asymptotics starting from the Drucker-Prager model for viscoplastic materials, in which we have to make several assumptions. Additionally to the classical ones that are that the curvature of the topography, the width of the layer of material, and the viscosity are small, we assume that the internal friction angle is close to the slope angle, the velocity is small, and the pressure is convex with respect to the normal variable. The assumption that the internal friction angle has to be close to the slope angle is necessary for the velocity to remain small, and the convexity of the pressure is an assumption of stability of the double layer static-flowing configuration. We present here the resulting model, that takes the form of an overdetermined initial-boundary problem in the variable normal to the topography. It handles arbitrary velocity profiles, and is therefore more general than previous models such as the BCRE model.

Hierarchical mobile IPv6 makes the mobility management localized.Registration with HA is only needed while MN moving between MAP domains.In this paper,the author proposed an adaptive mobility management scheme based on the hierarchical mobility IPv6.The scheme focuses on the MN operation as well as MAP operation during the handoff.Adaptive MAP selection algorism can be used to select a suitable MAP to register with once MN moves into a new subnet while MAP can thus adaptively changing his management domain.Furthermore,MAP can also adaptively changes its level in the hierarchical referring on the service load or other related information.Detailed handoff algorism is also discussed in this paper.


Abstract Female yellow dung flies have large paired accessory reproductive glands, the function of which remains unclear. However, gland contents are secreted during copula and egg laying. Other female flies produce a range of anti‐bacterial substances in their accessory reproductive glands that protect them and their eggs from pathogens, and it is possible that gland secretion acts similarly in yellow dung flies. A series of experiments was conducted to test this idea. Because the volume of secretion remaining in the glands is negatively related to copula duration, egg hatchability and longevity of females was compared in groups that copulated experimentally once or three times. A zone inhibition assay was used to see if gland extract inhibited bacterial growth. Egg number was positively associated with female body size, but the proportion of eggs hatching was not. Neither copula number nor duration influenced egg number or hatch number or proportion. In accordance with this, gland extract did not inhibit bacterial growth. However, female longevity was reduced in females that copulated with more males. This suggests that gland secretion does not serve to protect eggs, but as with a number of taxa, copula is costly to female yellow dung flies.


The main goal of this letter is the analysis of the multipactor effect within a coaxial waveguide excited by an RF pulsed signal. The variation of the multipactor RF voltage threshold with the ON interval length of the pulse has been analyzed. To reach this aim, an in-house multipactor simulation code based on the Monte-Carlo algorithm has been implemented. The numerical simulations show that the multipactor RF voltage threshold increases as the ON pulse interval diminishes. In addition, an experiment was carried out to validate the proposed theoretical model, and demonstrating the excellent agreement between the theory and the experimental data. Finally, the results are compared with the 20-gap-crossing rule used in the space standard document (ECSS-E20-1A).


This Innovative Practice Full Paper presents a case study on constructing and implementing a connected program in the Doctor of Science (D.Sc.) in Cybersecurity at Marymount University. We adapted a connected curriculum framework to this professional doctorate program based on two overarching pillars: andragogy theory and a multidisciplinary perspective. We use an andragogical instructional methodology that follows a learner-centered teaching philosophy to promote professional and adult learner engagement. Furthermore, the D.Sc. program takes a multidisciplinary approach to bridge and integrate domain-specific silos such as technology and its evolution, risk management, legal compliance, human factors, machine learning, business impact, and more. This integration helps enhance students' knowledge in multiple disciplinary specializations, focusing on problem-solving skills across the various domains important in cybersecurity. Building on these two pillars, our connected program model integrates five dimensions of connectivity to connect 1) academic learning and research with the workplace, 2) research activities and research-related curriculum over time, 3) various disciplines related to real-world cybersecurity challenges, 4) students with each other, across phases and with alumni, and 5) students with research and researchers across multiple domains. This paper's primary contribution is to demonstrate an innovative andrological and connected approach to tackle the ever-changing cybersecurity threats by cultivating the next generation of cybersecurity leaders with both advanced technical and refined management skills. We further showcase the potential of externalizing this framework in other settings and discuss future research work.


Die-to-wafer direct hybrid bonding process is foreseen as a key enabler of heterogeneous 3D integration. Hybrid bonding technologies were first developed on W2W assembly reaching 3D interconnection pitch of $1\mu\mathrm{m}$. Recently, CEA-Leti demonstrated the feasibility of DTW direct hybrid bonding at $10\mu\mathrm{m}$ with a specific die bonder (NEO HB) developed by SET Corporation. In this paper, the last improvements of DTW hybrid bonding process flow and die bonder alignment capability are presented. Main results showed an alignment capability improved to $<\!1\mu\mathrm{m}$ which enables bonding of die with $<\!5\mu\mathrm{m}$ interconnection pitch. Finally, multi-interconnection pitch bondings on a wafer were achieved with Cu pitches varying from $5\mu\mathrm{m}$ to $10\mu \mathrm{m}$.


In order to find the design law that enables a mid-loaded turbine blade to be inserted into an aft-loaded turbine blade,the first stator of a four-stage power turbine was researched by the three-dimensional fluid dynamics software NUMECA.The camber curve and side curve of the blade were controlled by using a Bezier curve.Numerical simulation shows that when keeping the axial length invariant,narrowing the tangential length of the camber curve of the turbine and in the meantime increasing the thickness of the blades can control the throat area,and thereby obtain aft-loaded turbine cascades,which are advanced in performance and matching with the original ones.Study of three-dimensional flow fields shows that aft-loaded turbine cascades can reduce both profile loss and secondary flow loss.The new turbine cascades which are characterized by aft-loaded airfoil increase the turbine efficiency by 0.62%.
