The lowest measurable magnetic field of a high sensitive magnetometer based on giant magnetoimpedance (GMI) effect will be determined by its noise level. Numerous previous works have showed that the equivalent magnetic noise level of GMI magnetometer presents a 1/f behavior at low frequencies and a white noise. Currently, performances of the magnetometer are still limited by the electronic conditioning as well as the intrinsic equivalent magnetic noise of the GMI sensor. To improve sensor performances, particularly at low frequency, we have investigated two focuses on research: 1) reduce the electronic noise of the conditioning electronic by increasing the voltage sensitivity, in units of V/T and 2) reduce the intrinsic equivalent low frequency sensor noise. As previously reported, the equivalent magnetic noise at 1 Hz can be reduced by increasing the excitation current in addition to a dc bias current. By working on these bias conditions, on the given samples, we almost 1 pT/√Hz in white noise region and 15 pT/√Hz at 1 Hz.


Background:Restenosis after successful percutaneous transluminal coronary angioplasty remains the major clinical problem limiting the long-term efficacy of the treatment. Recent advances in the understanding of the biology of restenosis indicate that its cause is predominantly a multifactorial stimulation of smooth-muscle cell proliferation. The aim of this study was to investigate the in-vitro effect of antineoplastic agents on smooth-muscle cells isolated from human coronary plaque material. Methods:Atherosclerotic tissue from coronary arteries was extracted from 15 patients of both sexes by thrombendarterectomy. Cells were isolated using enzymatic disaggregation and identified to be smooth-muscle cells with fluorescent antibodies for smooth-muscle-specific α-actin. The antineoplastic agents cytarabine (500–0.005 μg/ml), doxorubicin (50–0.0005 μg/ml), and vincristine (10–0.0001 μg/ml) were added to the cultures. Six days after seeding, the cells were trypsinized and then counted. Results:All three antineoplastic agents had a strong dose-dependent antiproliferative effect on cultured smooth-muscle cells. After the application of cytostatic agents, cells either became rounded or underwent complete lysis. Cytoskeletal elements, such as actin. microtubules, and vimentin, were largely altered. Conclusion:This investigation examined the potential role of antineoplastic therapy in the prevention of restenosis after coronary angioplasty. The development of new intravascular delivery systems, such as coated stents, may open the way for local antiproliferative strategies in interventional cardiology.

The method comprises the steps of shooting a user real scene image, displaying the user real scene image on an intelligent terminal screen, overlaying virtual characters into the user real scene image, obtaining position information in a moving process of the intelligent terminal, judging whether change of the position information of the intelligent terminal exceeds a preset threshold value, and if the change of the position information of the intelligent terminal exceeds the preset threshold value, and moving the virtual characters in the user real scene image according to the position information of the intelligent terminal. An interactive scene of users with the virtual characters is not a virtual scene any more but a real actual scene, the number of scenes and the content of the scenes are infinite, and therefore interactive efficiency in the manner is improved.


In this paper, we consider in R n the Cauchy problem for the nonlinear Schrodinger equation with initial data in the Sobolev space W s,p for p n(1 ― 1/p). Moreover, we show that in one space dimension, the problem is locally well posed in L P for any 1 < p < 2.


A new class of peptide mimics termed "γ-AApeptides" has been described. The design and synthesis of γ-AApeptides, and potential bioactivities towards p53/MDM2 interaction were demonstrated. γ-AApeptides were also found to be highly resistant to proteolysis. The development of sequence-specific γ-AApeptides may lead to a family of peptidomimetics with a new framework for drug discovery or peptide/protein mimicry.

In this paper, a large-scale experimental study has been conducted in order to evaluate the high-velocity compaction of aluminum powder using Gas Detonation Forming (GDF) processing technique. In this series of experiments, the effect of the distribution of grain particle size, initial powder mass, and loading conditions on green density and strength of compacted products were thoroughly studied. The maximum relative green density and green strength of 97.6% and 17.9% were achieved. Group Method of Data Handling (GMDH)-type neural network in conjunction with Singular Value Decomposition (SVD) method was exerted to model the high-velocity compaction process of aluminum powder. The main objective of this idea is to demonstrate how two characteristics of the high-velocity compaction, namely, the relative green density and strength of products vary with the changing of significant parameters, involved in GDF processing technique.


A new journal is introduced which disseminates the results of research conducted at or in association with the University of Kansas on fossil insects and their relatives. The journal spans all aspects of paleoentomological research, extending beyond systematic studies to include works on insect-bearing deposits, and their taphonomy and ecology.


Abstract Background In England, coronary heart disease (CHD) mortality has declined, but variations remain. Methods This study aimed to describe under 75-year CHD mortality variations across geographically defined populations. Regression slopes for mortality data as a function of time were calculated for all 151 English primary care trusts (PCTs), giving the change in the expected age adjusted rate for each extra year. Results Between 1993 and 2010, the mean age-standardized CHD mortality rate decreased from 107.76 to 35.12 per 100 000, but the coefficient of variation increased from 0.21 to 0.27. The slope of decline was significantly less after 2004 (β −4.91 for 1993–2003, −3.04 for 2004–2010). The proportion of smokers decreased by 24.6%. The estimated proportion of the population with controlled hypertension increased by 74.4% (2003–2010), but diabetes increased by 138% (1994–2010) and the proportion of obese people increased by 74.3% (1993–2010). There was a greater decline in CHD mortality in PCTs with greater deprivation and smoking (2006–2010). Conclusions Since 2004, there has not been a relative reduction of variations in CHD mortality. Appropriate strategies to improve early detection and effective management of risk factors are needed to lower overall CHD mortality further and to reduce persistent variations across England.


In their Comment (X. Yin, E. F. Holby and P. Zelenay, Energy Environ. Sci., the comment.) entitled "Kinetic degradation models of Fe–N–C electrocatalysts for the oxygen reduction reaction (ORR) and mechanistic implications", Yin, Holby and Zelenay declared that the INRS model, analyzing and interpreting the instability of our NC_Ar + NH3 highly active, high performance, but unstable Fe/N/C catalyst in a PEM fuel cell, contains several essential misconceptions that weaken the validity of the conclusions regarding the degradation mechanisms that we might draw from our model. In particular, they address two main issues that they believe are not valid: (i) the inclusion of non-kinetic effects in kinetic modeling, which, according to them, will prevent us from obtaining true kinetic information about the loss of FeN4 active sites when the decay of the current density of the catalyst is measured at 0.6 V in PEM fuel cells; and (ii) inconsistencies in the thermodynamics underpinning the proposed degradation mechanisms. Here, according to their Comment, the cohesion energy of bulk (metal) iron would be disregarded in our thermodynamic calculations of the demetallation equilibrium constant (Kc) of FeN4 sites in the acid medium of PEM fuel cells. This would lead us to false conclusions about the Kc values determined for all FeN4 demetallation reactions that were considered in our model. Four of our recent publications are targeted in this Comment: two main ones, published in Energy Environ. Sci., 2018, 11, 365–382, and 2019, 12, 3015–3037; and two satellite ones, published in J. Electrochemical Society, 2017, 164, F948–F957 and 2019, 166, F3277–F3286. In this reply to their comment, we demonstrate that the conclusions drawn in the four targeted publications remain valid and that the arguments expressed in the Comment are unfounded. The fast decay in PEM fuel cells of a highly active, high performance, but unstable Fe/N/C catalyst like our NC_Ar + NH3 does not follow an electrochemical but a chemical mechanism which is governed (in conjunction with Le Chatelier's principle) by the thermodynamic equilibrium constant (Kc) of the demetallation reaction of its ORR active FeN4 sites in the catalyst micropores.


In a multilingual country like India, a document may contain words of text in more than one language. In this environment, multi lingual Optical Character Recognition (OCR) system is needed to read the documents. It is necessary to identify different layout regions of respective language before feeding the document to the OCR system. This Project Work Proposes prioritized requirements of Andhra Pradesh region. Hence, the documents of Andhra Pradesh Government are generally printed in Telugu, and English languages. Certain documents produced in private and Government sectors, like railways, banks, post-offices of Andhra Pradesh are of tri-lingual (a document having text in three languages) type. When it comes to automation, assuming that there are three OCRs for Telugu, and English languages, a preprocessor is necessary by which the language type of the different texts lines are to be identified. In this Work, a script identification technique to identify the text lines of Telugu, and English languages from a bilingual document is presented. In this Work, a simple and efficient technique of language identification for Telugu, and English text lines from a printed document is presented. The proposed system is based on the characteristic features of Stroke and Cursive nature of individual text lines of the input document image. The feature extraction is achieved by finding the behavior of Strokes in individual word boundaries from a printed bilingual document image. Keyword's—OCR (Optical Character Recognition), Multilingual, Language, Bilingual language I.INTRODUCTION In recent years, the demand for tools to be able to recognize, search and retrieve written and spoken sources of multilingual information has increased tremendously. With the rapid explosion of online repositories, researchers and developers of crosslingual search and translation systems can get a lot of resources they need easily from the Internet. However, there are still significant resources that can only be accessed in a printed form, especially for sparse, low density languages. Manipulation and conversion of these printed documents is essential for many researchers and organizations. One of the most important tasks to address with printed documents is the automatic recognition of text, which usually consists of three steps: (1) zone segmentation and text region identification using document layout analysis; (2) text line, word and character segmentation; and (3) optical character recognition (OCR). In the last step, OCR systems are often designed to work on documents with the specific script. In order to parse bilingual or multilingual documents such as patents1 or bilingual dictionaries, or perform multilingual document retrieval, the script must be identified before feeding words to an appropriate OCR system. Language identification is an important topic in pattern recognition and image processing based automatic document analysis and recognition. The objective of Language identification is to translate human identifiable documents to machine identifiable codes. The world we live in, is getting increasingly interconnected, electronic libraries have become more pervasive and at the same time increasingly automated including the task of presenting a text in any language as automatically translated text in any


Abstract CONSIDERABLE data have been colected on feed used by turkeys at different age and weight periods but the greater part has been based on flocks composed of both sexes, with limited information having been obtained where the sexes were separated. Data reported by Brooks (1933) on Bourbon Red turkeys from 18 to 28 weeks of age with males and females separated, showed male turkeys used feed more efficiently than females; that is, a pound of weight was produced on less feed by the males than by the females. The average gains were greater and more consistent each week for males than for females. Males ate more feed each week per bird than females but less in relation to their body weight or gain in weight than females. Bourbon Red males raised in strict confinement consumed an average of 6.0 pounds of feed per pound of gain made between the ages . . .


In response to the late Dr Brackenridge's article (i) on some dilemmas posed by plans to combat Huntington's disease DrKottow discusses three issues which any proposal to introduce a new way of combatting disease must address. First, how good is the research and the rationale underpinning the new proposal ? Research indicates that the proposed use of levodopa provocation to detect Huntington's would be inefficient and potentially dangerous. Second, how can the developing knowledge be beneficially applied in practice ? The information available suggests that in practice no reasonable options offering more benefit than harm could be offered to potential sufferers. Third, who should make the choice, once reasonable options do become available DrKottow argues that this should be left to the patient once information has been passed to him 'in a tactful and humane manner'.


The British Government has announced that the entire body of EU law will be adopted into UK Law through the 'Great Repeal Bill' at the moment of withdrawal from the European Union (EU) with 'unnecessary legislation' then gradually repealed. However, many commentators have pointed out the enormity and complexity of this task as well as the political, economic and constitutional hurdles to legislative reform. For plant biosecurity, a crucial issue taken into account when shaping the current EU plant health regime through the Directive 2000/29/EC ('Plant Health Directive') was the need to embrace the single market. Furthermore, the UK was influential in safeguarding plant health in the single market through the adoption of this Directive. The impact of Brexit on protection from invasive species damaging habitats and wildlife (EU Regulation 1143/2014) should also be considered. With the Brexit White Paper published and with the Article 50 Bill passing through Parliament, the following questions should be asked:
• Will Directives as well as EU Regulations be included in Great Repeal Bill?
• If so, will Directive 2000/29/EC be regarded as 'unnecessary' given UK's likely departure from the single market and what might replace it?
• Will existing rulings of the ECJ be taken into account in implementation of laws originating from the EU?
• Will risks of introduction of harmful organisms and invasive species increase or lessen if the UK's borders retract to her national boundaries?
• What will happen with plant passporting?
It will also be necessary to take into account the impact of Brexit on legislation on plant protection products/pesticides because plant health is a component of the EU Farm-to-Fork food safety strategy. Consequently, another question to be addressed is:
• Will the UK continue to implement the farm-to-fork strategy after Brexit strategy or will it be abandoned in favour of a narrower sectoral approach?

Kerala Financial Corporation (KFC) is one of the eighteen State Financial Corporations (SFC) established for promoting Micro, Small and Medium Enterprises (MSMEs) in India. The major problem faced by the small and medium scale entrepreneurs is to get adequate credit facility at affordable interest rates. In this scenario, it is very important to conduct a study relating to the performance of KFC in promoting MSME segment in Kerala. This article has two main objectives, mainly to scrutinize the function of KFC in promoting the MSME segments in Kerala and to advise appropriate measures for the development KFCs and the MSMEs they help. This research paper is based on the performance of KFC in the last 6 years (2012-13 to 2017-18). The data were collected through secondary sources like articles, journals, manuals and annual reports of KFC, and analyzed using different financial and statistical tools like average, standard deviation and average annual growth. The findings of the study indicate that the operational performance of KFC was affected negatively due to decrease in Net Profit and Loan operations of KFC were subdued in certain districts like Kollam, Pathanamthitta, Alappuzha and Palakkad. The recommendations based on the findings are also discussed in this paper.


This study aims to conduct a study on the use of various types of oil as a source of energy in native chickens. The treatments of this study were: native chickens were fed without using oil (A), using 3% coconut oil (B), using 3% used cooking oil (C), using 3% pork oil (D), using 3% fish oil (E). The variables observed in this study were: nutrient digestibility and performance of native chickens aged 10 weeks. The results showed that the substitution treatment for different types of oil in the native village ration had no significant effect on nutrient digestibility. Substitution of 3% used cooking oil in the feed of native chickens aged 10 weeks had no significant effect on performance, while substitution of 3% palm oil, 3% fish oil, 3% pork oil could improve the performance of native chickens aged 10 weeks. It can be concluded that substitution of used cooking oil is not recommended in native chicken feed, while palm oil, fish oil, and pork oil can be used as substitutes in native chicken feed.


Of the many factors that may combine to produce school problems, learning disabilities constitute the most prevalent underlying cause. This article is devoted to a better understanding of this complex disorder. Following a brief discussion of diagnosis, etiology, and prevalence, the focus will be on controversies surrounding therapy arising from recent outcome studies and the attention given to dietary treatment. Objectives of this report include reviewing the evidence that suggests limitations of medication as the only treatment for this disorder, some of the possible harmful effects of medication, and the efficacy of diet as a mode of therapy. The discussion will also acquaint the clinician with major aims of therapy and suggest multiple approaches to treatment.
 DEFINITION AND TERMINOLOGY
 Learning disabilities can be broadly defined as a cluster of biologically based disturbances in development that significantly impair school performance. These developmental problems fall into two broad categories that differ in the kind of symptoms that predominate, the manner in which school performance is affected, the regions of the central nervous system most likely involved, and the types of therapy needed. The first category affects primarily the acquisition of specific academic skills (such as reading individual words, spelling, handwriting, and mathematic computation) information remains intact.


Biomechanics of the spine is a vast area of research that has generated numerous studiesin recent years on the part of doctors (mainly orthopaedic surgeons), bioengineers and physicists. This paper is a short introduction to some of the topics of major interest in spine biomechanics. The first topic is the development of the spine with a "mechanical" explanation of the physiological curvatures. As the spine is a multiarticular complex structure, understanding the mechanism responsible for its dynamics requires in-depth knowledge of the spine's basic components: the vertebrae and their architecture, the intervertebral joints, the ligaments and muscles. A short morphofunctional description of each of these anatomical parts is given mentioning their biomechanical features. Of particular interest, in relation to spinal trauma, is the architecture of the cancellous bone of the vertebrae responsible for most resistance to compressive weight loads. This specific characteristic is gradually lost over the years either due to disease or to a progressive resorption of the horizontal lamellae and thinning of the vertical columns typical of osteoporosis. Numerous studies have been conducted in vivo and in vitro to shed light on the mechanisms leading to particular traumatic lesions or degenerative arthrosis. These have given rise to various theories formulated to account for the distribution of loads and strength in the elements making up the functional spinal unit. These theories include the old "two vertical columns" theory, subsequently replaced by the "three columns theory", and the latest "four columns" model which divides the spine longitudinally depending on carrying strength. The latest theory was formulated in the wake of in vivo CT studies using an axial loading device which allows axial loads to be applied even though patients are in a supine position. A short mention is made of the possible biomechanical applications of neuroradiological techniques, namely cine-MR scans, which allow detailed study of the ligaments, muscles and disc, especially the cervical spine under dynamic conditions. Lastly, the controversial concept of spinal stability and instability is discussed. Further studies are necessary to establish appropriate criteria for treatment of traumatic or degenerative lesions since an impairment to spine statics can result in permanent neurological damage.

...but who shall organize the local economy?

When looking for tools for recovering from the present economic crisis, the streghtening of local economies often arises as a possible alternative. The aim of the present paper is to examine which organization can best be capable of organizing and coordinating a local economy. We shall look for an organization that has a live connection to the rural business sector. Our micro-regional research in 2011came to the conclusion that local governments are the best candidates for this role and that social economy might be the best form for fulfilling this function.

Keywords: local economy, social economy, local governments, rural development


Abstract After modest but optimistic expansion in the 1940s, the geography program at Harvard University was suddenly terminated in 1948, touching off a widely publicized "academic war over the field of geography." It was a severe blow to the discipline, not only because of Harvard's position in American education but because in the course of the closure the President of Harvard University suggested that geography was not an appropriate university subject. The disciplinary history of the Harvard episode is dominated by oral accounts and discussions of personalities, but a more detached archival reconstruction of events is necessary today, if only to reclaim what actually occurred and thereby to allow us to understand it less defensively. For whatever the role of specific personalities, and Isaiah Bowman appears to have been more instrumental than is generally realized, there is a larger question concerning the vulnerability of geography, at Harvard and elsewhere. In the course of the termination and reconsideration of geography at Harvard, several key issues emerged concerning the efficacy of the discipline, and these are still relevant today. While this is mainly a historical reconstruction, therefore, it also touches on themes of contemporary relevance. For it may be that today as well as in Harvard in 1948, the discipline itself bears some responsibility for the failures that occur.


In this paper we compare the performance of different full-frame and block-based algorithms for the temporal alignment of two video sequences. The setup is typical for full reference video quality estimation in a low-bitrate scenario. Lossless and lossy digital transmission scenarios are combined with different distortions usually found in playback devices. The results show that the choice of the algorithm for temporal registration depends very much on the type of additional distortion expected.

We discuss the optimal spin bases for describing angular correlations in single top quark events at the Fermilab Tevatron. We define spin bases that exploit the fact that the top quarks are produced with 100% polarization along the momenta of the d-type quarks in these events. For single top production through an s-channel W boson, 98% of the top quarks have their spins in the antiproton direction. For single top production via Wg-fusion, 96% of the top quarks have their spins in the spectator jet direction. The direction of the top quark spin is reflected in the angular correlations of its decay products. Until the discovery of the top quark, most studies of spin in high energy physics were formulated in terms of the helicity basis. For ultrarelativistic particles, this is appropriate. However, in general, the direction and degree of polarization of a massive spinning particle depends on how it was produced. Thus, for moderate particle energies, it should not be surprising to find that the optimal axis for studying spin correlations is something other than the particle's direction of motion. For the case of single top quark production at the Tevatron, all of the Standard Model diagrams contain a common subdiagram: somewhere there is a ud quark line which is attached to a tb quark line via a W boson. The exact orientation of this subdiagram depends on the process being considered. However, the fact that the W boson couples only to fermions with left-handed chirality leads to a 100% polarization of the produced top quark in the direction of the d-type quark. 1 Thus, in studying the spin correlations in single top production at the Tevatron the two key questions are " Where is the d-type quark? " and " How well can we know the location of the d-type quark? " Before answering these questions, let us clarify exactly what we mean when we state that the top quark spin points in the direction of the d-type quark. As the first step, consider the correlations among the decay products of a spin up top quark. The dominant Standard Model decay chain is W + b t { l + ν du (1) For concreteness, we will describe the leptonic W decay. However, everything which we say about the charged lep-ton applies equally to the d-type quark in a hadronic decay. We define the decay angles in the …

Background Neonatal asphyxia is the major cause of neonatal death at a rate of approximately 23%. The incidence of asphyxia is higher in developing countries, due to limited availability of perinatology facilities. Hypoxia due to asphyxia is characterized by low pulse oxygen saturation (Sp02), which basic health care facilities are unable to monitor. The number ofnucleated red blood cells (nRBCs) in asphyxia increases in order to compensate for the hypoxia. Few studies have reported on nRBCs as they relate to pulse oxygen saturation in neonatal asphyxia. Objective To assess for a correlation between nRBCs and pulse oxygen saturation in neonatal asphyxia. Methods In this cross-sectional study, asphyxia was assessed by way of Apgar scores; pulse oxygen saturation was monitored by pulse oximetry; and nRBCs were determined by blood smears. Statistical analysis used was Spearman's test. Results Subjects were 41 neonates with asphyxia, 15 of whom had 5th minute Apgar scores S 6. Subjects with Apgar scores S 6 had significantly higher umbilical venous nRBC counts [20.0 (SD 13.09) /100 white blood cell] than subjects with Apgar score > 6 [8.81 (SD 8.71) /100 white blood cell] ; (P = 0.004). Subjects with Apgar S 6 had significantly lower 5th minute Sp02 values [76.46 (SD 6.17) %] than subjects with Apgar scores > 6 [87.03 (SD 6.29)]; (P < 0.0001). Spearmans' test revealed a significant correlation between higher nRBC counts and lower pulse oxygen saturation (r = -0.804; P<0.0001) . Conclusion In asphyxia neonatorum there is a correlation between umbilical vein nRBC counts and the 5th minute Sp02. As such, we recommend using nRBC examinations to predict pulse oxygen saturation as a means to assess the severity of hypoxia in peripheral areas where pulse oximetry machines may be unavailable

Abstract: The amphipod HyalellaSmith, 1874 is exclusive to the Americas, and the South region of Brazil presents the greatest diversity of the genus. This paper presents two species of Hyalella from Santa Catarina state, Brazil. A new species from the municipality of Palmeira is characterized by oval eyes, absence of flanges, epimeral plates not accuminated, presence of three lateral pappose setae on article 4 in antenna 2, absence of plumose setae in the maxilliped, presence of comb-scales and absence of serrate setae in the gnathopods, presence of curved seta on the inner ramus of the uropod 1 and absence of lateral setae on the telson. A new species from Rio das Antas municipality main characteristics are absence of flanges, epimeral plates accuminated, absence of plumose setae and distal nail in the maxilliped, presence of comb-scales and absence of serrate setae in gnathopods, presence of curved seta on the inner ramus of the uropod 1 and absence of lateral setae on the telson. Here we expand the distribution and increase the morphological and taxonomic knowledge of the genus.


Professor Stanford thinks that the emotional elements of Greek tragedy have been unduly neglected, and he offers the present book as an introductory study of how the tragedians represented emotion and how they aroused emotion in their audiences. In ch. 1 he discusses ancient evidence for ' strong emotionalism among Greek theatrical audiences' (p. 3). Views will differ about the reliability of some of the stories that he cites, and his interpretation of the more plausible ones is sometimes open to question: there is nothing in Herodotus' account (6. 12. 2) of the Athenians' reaction to Phrynichus' Capture of Miletus that suggests ' an outburst of mass hysteria that threatened public order' (p. 5), and the point of the story, in any case, is that the Athenians' distress was not typical of their response to drama. Similarly, Odysseus' weeping at Demodocus' songs (Od. 8. 83-6, 521-31) is not due, as S. suggests (p. 50), to the emotional power of music but is an unusual reaction caused by his personal involvement in the events narrated. The usual and appropriate response to song in Homer is quiet attention and pleasure (cf. Od. 8. 91, 538, 542). Plato was surely more likely to exaggerate the effects of tragedy for being hostile to it (just as modern campaigners against pornography make more of its effects than liberals) and is not 'all the better as a witness for being hostile' (p. 3).


It is shown that ohmic losses in current carrying conductors at nonzero frequency can be decomposed into two parts. One part is due to a current distribution that would have existed within the conductor at zero frequency (dc current distribution). The other is due to excess current distribution defined to be the difference of the actual current distribution at nonzero frequency and the dc current distribution. An integral equation for the computation of excess current distribution is derived and an easily computable upper bound on the excess losses is found. This upper bound is used to estimate the total eddy current losses and the accuracy of this estimate is tested for long wires of circular cross section. This estimate is shown to be accurate if the wire radius is about the same or smaller than the skin depth.


Natural gas is stored in underground reservoirs at 37 locations in Illinois. These reservoirs contain more than 580 billion cu ft of gas, about one-third of which is working gas and two-thirds is cushion gas. Potential usuable capacity of these reservoirs is estimated to be 1.2 trillion cu ft. At 11 of the storage projects, gas is stored in depleted, or partially depleted, gas reservoirs. One depleted oil reservoir is used for storage, and in the remaining projects, gas is stored in aquifers that originally contained no hydrocarbons in commercial quantities. At 4 locations, 2 reservoirs at different depths are in various stages of exploration, testing or development for storage. Two projects have been abandoned. Rocks of all systems from Cambrian to Pennsylvanian are used for storage of gas in Illinois. However, most of the storage volume is in sandstone aquifers of Cambrian and Ordovician age. (50 refs.)


A methodology to estimate waveform parameters of unknown interfering signals and number of interfering sources within the field of view of victim radar (VR) is presented using real time measured data. On the basis of identified interference parameters, waveform parameters of VR can be cognitively adapted to mitigate interference using 'sense and avoid' approach.


This study investigates the nature of narrating experiences of difficult life events among Swedish young adults. In doing so, we address a cultural framework for telling identity narratives of difficult experiences. Building on extant work on the importance of the narration of difficult life events for identity and wellbeing, we examine how these stories are narrated in the Swedish context, and relations between patterns of narration and well-being. Identity narratives about life challenges were collected from 116 participants (M age = 33.28, SD = .54, n = 58 women). Employing an open-exploratory approach, four equally prevalent emotional structures were found: redemptive structure, neutral/vague structure, combination of positive and negative structure, and negative structure. No differences were found in the use of the first three structures for well-being, but the negative structure was generally associated with poorer well-being. This study shows that there are several ways to narrate challenges in the Swedish context, and it sheds light on the ways in which culture informs the narrative identity.


An increase in the global energy confinement time ({tau}{sub {ital E}}) was obtained in the CTX spheromak by replacing the high-field-error mesh-wall flux conserver with a low-field-error solid-wall flux conserver. The maximum {tau}{sub {ital E}} is now 0.18 ms, an order of magnitude greater than previously reported values of {approx lt}0.017 ms. Both {tau}{sub {ital E}} and the magnetic energy decay time ({tau}{sub {ital W}}) now increase with central electron temperature, which was not previously observed. These new results are consistent with a previously proposed energy-loss mechanism associated with high edge helicity dissipation.


Like shared-memory multi-threaded programs, event-driven programs are susceptible to non-deterministic errors that are hard to reproduce and debug. Mobile application platforms and the web require writing event-driven code, motivating the need for better tools to detect these types of errors. In the first part of this talk, we will show how techniques from data race detection for multi-threaded programs can be applied to detect these bugs, by defining an appropriate notion of a happens-before relation and memory accesses for the underlying platform. While extant data race detectors can be applied to event-driven programs based on the above, the pervasive use of ad hoc synchronization in such programs can lead a race detector to report too many false positives. Race detection for such programs also faces a scalability challenge, as a large number of short-running event handlers can overwhelm standard vector-clock-based techniques. We present a novel race detector EventRacer that addresses both of these challenges. We introduce race coverage, a systematic method for exposing ad hoc synchronization and other key races to the user, significantly reducing false positives. We also present an efficient connectivity algorithm that uses chain decomposition to dramatically decrease the overhead of vector clocks. We show that for client-side web applications, our techniques lead to large performance and precision improvements over state-of-the-art techniques.


Rotational spectra of the N-methylformamide HCONHCH3 molecule were recorded in the frequency range between 45 and 630 GHz. Analysis was carried out for the trans conformer of the molecule using the Rho axis method where the quadrupole hyperfine structure was taken into account in the first order of perturbation treatment. The analysed dataset for trans conformer contains 18914 A and E transitions with J ≤ 62 in the ground, first, and second excited torsional states. A fit within experimental error is achieved with weighted root-mean-square deviation of 0.85.


Fitzjames Stephen, disliking his "insolent & domineering affectations" and ternling him "ignorant ," "presumptuous," "oddly inconsistent ," "always brutal," and "very vain." even if "he is undoubtedly a clever man" (IV, 1,600). Of his relationship to his wife, Harriet Taylor hlill, 136 letters to her take up most of the first volume. On the whole I found them boring, filled ,\jth tedious accounts of his poor health and household burdens and banal reports of his travels. These letters amply reveal not only his devotion and exaggerated regard for her intellect-typically, in a letter to Louis Blanc, he termed her "the greatest mind" in England (11, 601)-but also her role in the formation and developnient of his ideas. (The latter question is gnely examined in the editor's introduction.) Finally, there is much testimony in these letters both to his generosity in acknowledging and encouraging the work of others-old friends like George-Grote (e.g., 111, 1,115-1,116, 1,120-1,121) and John Elliot Cairnes (IV, 1,663-1,666) but also younger men like John Venn (11, 1,360-1,361)-and to his coldness in some personal affairs, particularly wit11 members of his family and Theodor Gompcrz's abortive pursuit of Helen Taylor (11, 8544355,865-866). No one interested in hlill, his contemporaries, and the problems of his age can fail to find much in these volumes of major interest. All the more so since hlill's work, as he himself recognized, "lies rather among anticipations of the future than explanations of the past" (IV, 1,873).


We have measured the fundamental acetylenic C–H stretch near 3.0 μm of (CH3)3C–C≡CH and (CH3)3Si–C≡CH using an optothermal, molecular beam spectrometer. We find that the individual R(J) lines of the hydrocarbon are Lorentzian with a FWHM of 800 MHz indicating statistical intramolecular vibrational relaxation (IVR) with a 400 ps lifetime. The R(J) lines of the silicon compound are clearly asymmetric and, in addition, show a FWHM of about 150 MHz indicating a much longer (>2 ns) lifetime. The increase in IVR lifetime in the larger density of states molecule may be due to reduced kinetic coupling resulting from the heavier Si atom.


THE CORRELATION BETWEEN ANTENATAL CARE AND INFANT BIRTH WEIGHT IN INDONESIA (DATA ANALYSIS OF RISKESDAS 2010) Birth weight is an influential factor towards a person's health in adulthood. In Indonesia, the prevalence of babies with low birth weight was relatively high, amounting to 11.5% (Riskesdas 2007). The research objective of this study is to investigate the correlation between antenatal care and the birth weight of infants in indonesia. This study is a further analysis of Riskesdas 2010 data. The research sample is mothers with child under one year old and their birth weight data from Riskesdas 2010 are available. Total number of sample is 2926 pairs of mother and child. Variables studied include ANC, parity, age maternal on delivery, distance time between pregnancy, weighed during ANC, assessment on child height and blood pressure; urine and blood analysis (for Hb) were also collected ; TT injection and education on complication were given; economical status and height of mother were also gathered. ANC is considered satisfactory when there is at least one visit during the first trimester, once in second trimester and twice in the third. Data analysis was using logistic regression analysis. Result: Bivariate analysis shows that variables that are closely related to birth weight were significance (p<0,05) included ANC visit, inform on complication, and distance time between pregnancy. Multivariate analysis shows that there is a significant correlation between ANC and low birth weight with OR 1.8 (CI 95%: 1.3 2.5). This shows that mothers who have more than 4 ANC visits more likely to have 1.8 times less risk of having infants low birth weight as compared to those who only have less than 4 visits. There is no interaction among independent variables and confounding variables to the relationship between ANC and low birth weight incidence.


A supramolecular nanotube with diameter of about 5 nm was constructed from self-assembly of a pair of complementary molecular components, namely 5-(4-dodecyloxybenzylidene)-2,4,6-(1H,3H)-pyrimidinetrione and 4-amino-2,6-didodecylamino-1,3,5-triazine. Temperature dependent FTIR spectroscopy studies indicate that non-covalent interactions, such as hydrogen bond, π -aromatic stacking and van der Waals, result in the formation of the supramolecular nanotube.


Recent technological advances in the field of micro-electro-mechanical systems (MEMS) have made the development of multi-functional sensor nodes technically and economically feasible. The lifetime of sensor networks is still limited as individual sensor nodes are usually powered by battery. In the past few years, the use of relay nodes in sensor networks has been proposed in literature for balanced data gathering, reduction of transmission range, connectivity and fault tolerance. In hierarchical sensor networks, higher-powered relay nodes can also be used as cluster heads. These relay nodes may form a network among themselves and route data towards the base station. In such a sensor network, the lifetime of the network is directly related to the lifetime of these relay nodes. In this paper, we have proposed an ILP solution for scheduling the data gathering of relay nodes such that the lifetime of the relay node network is maximized. We have compared our formulation with the direct transmit energy model and shown that it can lead to significant improvements. We have also proposed a re-scheduling approach which can further extend the maximized lifetime of the network


Benzodiazepines (BZDs) are a class of drugs commonly prescribed to pancreatic ductal adenocarcinoma (PDAC) patients to treat anxiety, anticipatory nausea prior to chemotherapy, and insomnia. We discovered that approximately 1 in 4 pancreatic cancer patients are prescribed BZDs and that significant differences in survival outcomes are associated with the type of BZD prescribed. Lorazepam is associated with poorer recurrence-free survival (HR 3.83 (1.53,9.57)) while alprazolam is associated with improved recurrence-free survival (HR 0.38 (0.16,0.92)). We hypothesize that these differences in survival result from off-target activation of the proton-sensing GPCR, GPR68, by n-unsubstituted BZDs, such as lorazepam. GPR68 is preferentially expressed in PDAC cancer-associated fibroblasts (CAFs). We found that n-unsubstituted BZDs commonly prescribed to PDAC patients potentiate activation of GPR68 in the presence of acidity, subsequently promoting secretion of IL-6 by CAFs in a GPR68-dependent manner. Conversely, we found that n-substituted BZDs, such as alprazolam, decrease IL-6 secretion by CAFs in a GPR68-independent manner. Using a syngeneic KPC transplant model, we found that tumors from mice treated with lorazepam had increased expression of inflammatory signaling pathways and ECM-related genes by RNA sequencing. Histologically, lorazepam-treated tumors had increased levels of collagen, alpha-smooth muscle actin staining, and high levels of ischemic necrosis in the centers of the tumors. Overall, these findings indicate that benzodiazepines can modify the PDAC tumor microenvironment, which may subsequently impact chemotherapeutic efficacy and patient survival.

Despite the exponential growth in biomedical knowledge over the past century, the undergraduate medical curriculum has not increased in length. Faculty face a considerable challenge in developing curriculum that is up to date yet does not overwhelm learners with its sheer volume. The practice of continually adding content to an already extensive curriculum has been scrutinized by the Liaison Committee on Medical Education and has been linked as negatively contributing to medical student burnout, mental health, and physical wellbeing. The goal of this interview study was to: 1) gain a deeper understanding of how faculty develop curriculum in terms of selecting content and pedagogy, 2) describe the faculty's expectations of students inside and outside the classroom, and 3) describe the faculty's conceptual understanding of workload placed on medical students. Semi‐structured interviews were conducted with fourteen faculty members having major roles in delivering the M.D. curriculum. Interviews were recorded, transcribed and analyzed using thematic content analysis revealing several major interconnected themes. Overall, the faculty viewed student engagement with them and the learning materials as the key mediators of student success. Faculty described ideal learners as curious, self‐regulated students who regularly used self‐assessment of their learning. Faculty identified the need for students to read more outside of class in preparation for the active learning sessions provided. While faculty broadly acknowledged that overwhelming workload is a detriment to student engagement, they either did not have, or did not wish to have, access to tools that would allow them to better assess student workload. Some faculty perceived misalignment between student goals and curriculum objectives, which may foster an informal curriculum and contribute to an overload in total student effort. To maximize student engagement with the formal curriculum, we propose that faculty receive more information on the importance of considering workload when developing curriculum and receive tools to properly assess student workload.


This study examines and compares the microstructures, Vickers microindentation hardness, and mechanical properties for additively manufactured (AM) samples built by a variety of AM processes: wire arc AM (WAAM), electron beam powder bed fusion (EB-PBF), laser wire direct energy deposition (LW-DED), electron beam direct energy deposition (EB-DED), laser-powered direct energy deposition (LP-DED), and laser powder bed fusion (L-PBF). These AM process samples were post-processed and heat-treated by stress relief annealing at 1066 °C, HIP at 1163 °C, and solution annealing treatment at 1177 °C. The resulting microstructures and corresponding microindentation hardnesses were examined and compared with the as-built AM process microstructures and hardnesses. Fully heat-treated AM process samples were mechanically tested to obtain tensile properties and were also evaluated and compared. Principal findings in this study were that high-temperature heat treatment >1100 °C of AM process-built samples was dominant and exhibited recrystallized, equiaxed grains containing fcc {111} annealing twins and second phase particles independent of the AM process, in contrast to as-built columnar/dendritic structures. The corresponding yield stress values ranged from 285 MPa to 371 MPa, and elongations ranged from 52% to 70%, respectively. Vickers microindentation hardnesses (HV) over this range of heat-treated samples varied from HV 190 to HV 220, in contrast to the as-built samples, which varied from HV 191 to HV 304.


The severe accident of Fukushima Daiichi occurred on March 11, 2011, which originated from an earthquake and tsunami. There were six units in the Fukushima Daiichi nuclear power station. Units 1, 2 and 3 were operating and Units 4, 5 and 6 were shutdown at that time. It was estimated that partial or full core degradation occurred in all three operating units, according to the results of Phase I of OECD/NEA BSAF Project. Furthermore, it was estimated that a RPV lower head penetration failure might occur in the case of Units 1 and 3. Understanding the situation of the accident and tracking of the current molten corium locations are essential to conduct decontaminations and to control the site situations hereafter. Cooling of the reactor vessel and corium debris is one of the most important works to prevent or mitigate a severe accident. In the case of Units 1 and 2, it was well known that external water injection started after about 15 hours and 80 hours from the reactor scram, respectively. The amount of water reaching the reactor pressure vessel and the start time of the external water injection are crucial factors to remove the decay heat in the vessel and are directly related with the degree of core degradation. In this research, some relationships were observed between the core damage progression and the injection mass flow rate of water or the timing of the injection. Moreover, the actual injection water flow rate and the extent of fission products release were estimated by comparing the measured data (for instance, pressures of reactor vessel and drywell). MELCOR 2.1 was used in this study.

Vendor Profile Analysis The industrial purchasing function is among the most critical activities for ensuring the long-term viability of a firm. An effective purchasing department can substantially help trim a firm's operating costs, thereby enhancing profitability. [1] Moreover, purchasing increasingly is becoming important to the marketing success of a firm, in that purchasing's policies and procedures have an impact, albeit indirect, on the firm's marketing mix and ultimate customer satisfaction. [2] It is, therefore, essential for an organization to have a decisionmaking mechanism which ensures that vendors are objectively appraised, with the goal of optimizing purchasing decisions. This article examines a powerful, yet simple, technique for aiding industrial buyers with the prepurchase evaluation of vendors. This technique, referred to as vendor profile analysis (VPA), is designed for use with microcomputers using software, such as Lotus 1-2-3 and Symphony, capable of conducting Monte Carlo simulations. The technique is easy to understand because it is simply a modification of the "weighted point method." [3] The power of VPA stems from its use of Monte Carlo simulation for modeling decision makers' perceptions of uncertainty associated with predicting vendor performance. As will be shown, Monte Carlo simulation simplifies a decision maker's input to the evaluation model, and provides output that contains considerably more information upon which to base purchase decisions than do standard weighted point decision models. Some general background on current vendor analysis models is first presented. This is followed by a detailed discussion of the vendor profile analysis technique. BACKGROUND ON VENDOR ANALYSIS MODELS Suprisingly, there are few published models outlining normative techniques to assist industrial buyers engaged in prepurchase vendor evaluation. Traditionally, most published models have fallen into three categories: (1) categorical methods;(4) (2) weighted point methods; [5] and (3) cost-based techniques, such as the "cost-ratio" method. [6] Other models, not fitting these categories, include a model based on cluster analysis, [7] a sequential elimination procedure, [8] and a linear programming application. [9]These latter techniques, however, apparently are used only minimally. Timmerman provides an in-depth review of the mechanics, strengths, and weaknesses of the three traditional vendor evaluation techniques. [10] Because of space limitations and relevance to this discussion, only the weighted point method is reviewed here. Basic Structure of the Weighted Point Method Based on the number of published versions of the weighted point method, this is by far the most commonly used technique. Its basic structure is described by the following model: [Mathematical Expression Omitted] where [A.sub.j] = summated score representing the overall performance anticipated from vendor j [a.sub.i] = importance weight attached to evaluative criterion i [b.sub.ij] = performance rating on evaluative criterion i for vendor j n = number of evaluative criteria A typical purchase decision employing the weighted point method is presented in Table I. The decision begins with the identification and weighting of key dimensions (evaluative or choice criteria) required for evaluating alternative vendors. Column 1 of Table I enumerates possible criteria for examining alternative vendors of industrial equipment. Evaluative criteria are assigned importance weights ([a.sub.i]s) to emphasize their differential contribution to the purchase decision. Table I uses a simple five-point scale for this purpose (column 2) - more important criteria are assigned heavier weights. [Tabular Data Omitted] Decision makers next rate the expected performance ([b. …


The finite-time synchronous problem of complex networks with delays by way of periodicity and intermittency pinning control is investigated in this thesis. The finite-time synchronization conditions of directed networks are gotten in terms of finite-time stability theory, the differential inequality and the matrix theory. In addition, by combining periodically intermittent and pinning control methods, a periodically intermittent pinning controller is designed. Ultimately numerical modeling is presented to illustrate the effectiveness and validity of the consequences.


In Cuba, the municipal and regional development stems in large disparities and socioeconomic inequalities pre triumph of the Revolution of January 1959, and therefore of the need to invest efforts towards the ordering of the territories for development in relation to the revolutionary process. This study concerns the institutional framework of municipal development in Cuba and the effects of municipal development initiatives in other areas of participation and local development, with cases exemplifying.


In this paper,the movement course of blasting impeller shots after entering the windows has been analyzed.The velocity of shots flying off the windows has been deduced while no control cage is used.The velocity of shots in the pile formed in the windows has been deduced when the blast wheel is normally working.Further more,the critical localization of shots flying off the window in the control cage has been analyzed.These provided an important theoretical base for lengthening the life of the impeller and the control cage.


With the development of the power grid, high voltage transmission lines and smart substations are put into use. This requires higher-performance voltage transformers. Potential transformer(PT) can no longer meet the measurement needs. Analysis of the voltage measurement requirements in the power grid, pointing out the limitations of traditional PT such as poor insulation performance and ferromagnetic resonance. The principles, characteristics and application of three new voltage transformers, that is, resistance voltage transformer, capacitor voltage transformer(CVT), and optical voltage transducer(OVT) are described, and the practical problems of new voltage transformers are summarized and put forward.


Introduction: Numerous geophysical and geochemical studies have suggested the existence of a small metallic lunar core (e.g., [1-5]), but the composition of that core is not known. Knowledge of the composition can have a large impact on the thermal evolution of the core, its possible early dynamo creation, and its overall size and fraction of solid and liquid. Thermal models predict that the current temperature at the core-mantle boundary of the Moon is near 1650 K [6]. Re-evaluation of Apollo seismic data [7] has highlighted the need for new data in a broader range of bulk core compositions in the PT range of the lunar core. Geochemical measurements have suggested a more volatile-rich Moon than previously thought [8]. And GRAIL mission data may allow much better constraints on the physical nature of the lunar core [9]. All of these factors have led us to determine new phase equilibria experimental studies in the Fe-Ni-S-C-Si system in the relevant PT range of the lunar core that will help constrain the composition of Moon's core.


We survey and discuss the connection between three of the most fundamental problems in theoretical computer science: sorting, priority queues, and shortest paths. We will begin by illustrating the developments of priority queue-based shortest path algorithms from Dijkstra's original formulation to Thorup's results [8]. We will then move on to analyzing the connection between the aforementioned class of methods and the problem of sorting; in order to do so, we will present Thorup's results [10; 12] on the equivalence of sorting and priority queues. Finally, we will tie the discussion back to single-source shortest paths by showing the results obtained by Thorup [9], who studied methods that bypass the sorting bottleneck by relaxing the order in which the graph nodes are visited.


In this work, we report on single crystal growth and characterizations of a new scintillation material: CsSr1–xEux I3 (0 ≤ x ≤ 1). Single crystals of CsSr0.99Eu0.01I3, CsSr0.92Eu0.08I3 and CsEuI3 were grown via the Vertical Gradient Freeze method. The crystals exhibit good crystal quality, high light yield, and excellent energy resolution. Initial results show that the scintillation light yield of our CsSr0.92Eu0.08I3 crystal is ∼65,000 ph/MeV with 5.9% energy resolution at 662 keV. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)


The Centers for Disease Control and Prevention report 1 in 10 adults over the age of 60 have experienced some form of abuse including neglect and exploitation. However, these statistics are an underestimate. Professionals who interact with the elderly describe being reluctant to report abuse due to a lack of knowledge of elder abuse, the reporting process, and the resources available to support victims. The invisibility of elder abuse has only increased during the 2020 COVID pandemic due to the increased social isolation of older adults and understaffed, overburdened health and social systems. Cross-disciplinary education for healthcare and social service practitioners, law enforcement, court personnel, families, and the older adults themselves is an essential component to identify and prevent elder abuse. This chapter provides an overview of elder abuse and neglect categories, risk factors, and best practice interventions advocated for addressing elder victimization.


Abstract Determining the natural frequency of watermelon is important to reduce loss by vibration during transportation. The purpose of frequency sweep test is to determine the tolerance of watermelon to vibration within a certain frequency range and to search the resonant frequency of watermelon in a certain frequency range. Frequency sweep test of Xinong No.8 watermelon cultivar was conducted, and the acceleration transmissibility curve was obtained. Furthermore, the 1st and 2nd order natural frequencies of watermelon were determined as 35.125 Hz and 71.034 Hz respectively from the acceleration transmissibility curve. Based on Geometric and mechanical parameters of Xinong No.8 watermelon cultivar, a finite element analysis model was developed and modal analysis of watermelon was carried out to obtain its natural frequencies and mode shapes. Since the value of 1st and 2nd order resonance frequency were the same or similar to the value of 3rd, 4th, and 5th order resonance frequency, this study only focused on 1st and 2nd order modes. The 1st order and 2nd order natural frequency test data fit to the corresponding simulation data well which validated the FEA model. This study demonstrated the feasibility of detecting the resonant frequency of watermelon vibration during transportation using FEA methods and provided a theoretical basis for watermelon transportation device design to reduce damage by avoiding resonant frequency.


In 2006 a telehealth project was implemented in Medway for people with multi-morbidity problems, such as unstable blood pressure. Home monitors were provided to measure vital signs. The information was transmitted to a secure server where an electronic patient record was accessed by clinicians. If the monitored variables exceeded preset limits, an automatic alert was sent to the monitoring centre where trained operators took appropriate action, for example notifying a patient's clinician. In nursing home settings, monitoring was thought to have saved 127 hospital bed days and 112 nursing hours. In participants' own homes, monitoring was thought to have saved 1 33 hospital days and 117 nursing hours. There were also cost- and time-savings for general practitioners (GPs), practice and community nurses. Increased involvement in their own management gives patients a better understanding of their condition, resulting in increased reassurance and reducing the need for GP visits.

Purpose: To assess and compare the clinical outcomes of primary trabeculectomy with mitomycin C and Ahmed valve implantation for secondary open-angle glaucoma following uveitis. Methods: This study was conducted retrospectively on 30 eyes of 25 patients with open-angle glaucoma secondary to uveitis that had undergone trabeculectomy with mitomycin C and 33 eyes of 24 patients that had undergone Ahmed valve implantation. The clinical outcome indicators used in this study were intraocular pressure (IOP), number of anti-glaucoma agents, surgical success rate and occurrence of complications. Results: Mean IOP and surgical success rate in patients who had undergone trabeculectomy with mitomycin C after a 12 month postoperative period were 14.08.2 mmHg and 76.7%, respectively, while those of patients with Ahmed valve implantation were 13.27.7 mmHg and 81.8%. The data did not show clinical significance. There was greater risk of surgical failure in patients at a younger age and/or with diabetes mellitus in cases of having gone through trabeculectomy with mitomycin C. Conclusions: Both trabeculectomy with mitomycon C and Ahmed valve implantation can be considered as primary surgical treatments for patients with open-angle glaucoma secondary to uveitis. However, trabeculectomy with mitomycin C should only be applied to a limited extent in patients that are young and/or have diabetes mellitus.


Forearm and hand pathologies, such as trauma, infections, tumors or extensive burns, represent a genuine challenge for the orthopedic surgeon, considering the fact that they have a major impact on the patient quality of life. Amputations at this level, though rare, are often a lifesaving procedure, which helps minimize the severe complications that may occur. We present a retrospective study made on a number of 3203 patients which were admitted to an Orthopedic clinic, from 2012 to 2014. We analyzed which is the most frequent cause for upper limb procedures, the distribution in both genders, the average hospitalization period of time and we determined which is the higher occurrence between lower and upper limb pathologies, aiming to determine the prevalence of forearm and hand amputations in the studied group.


Opinion Lexicons are linguistic resources annotated with semantic orientation of terms (positive and negative) and are important for opinion min- ing tasks. In the literature we see a variety of proposals for the construction of opinion lexicons using different linguistic resources and techniques. In this work, we propose and evaluate the integration of such linguistic resources to create a single lexicon for the Portuguese language.


Several studies have revealed a correlation between chronic inflammation and NAD+ metabolism but the precise mechanism involved is unknown. Here we report that the genetic and pharmacological inhibition of nicotinamide phosphoribosyltransferase (Nampt), the rate-limiting enzyme in the salvage pathway of NAD+ biosynthesis, reduced oxidative stress, inflammation, and keratinocyte DNA damage, hyperproliferation and cell death in zebrafish models of chronic skin inflammation, while all these effects were reversed by NAD+ supplementation. Similarly, genetic and pharmacological inhibition of poly ADP-ribose (PAR) polymerase 1 (Parp1), overexpression of PAR glycohydrolase, inhibition of apoptosis-inducing factor 1, inhibition of NADPH oxidases and reactive oxygen species (ROS) scavenging, all phenocopied the effects of Nampt inhibition. Pharmacological inhibition of NADPH oxidases/NAMPT/PARP/AIFM1 axis decreased expression of pathology-associated genes in human organotypic 3D skin models of psoriasis. Consistently, an aberrant induction of both NAMPT amounts and PARP activity was observed in lesional skin from psoriasis patients. In conclusion, hyperactivation of PARP1 in response to ROS-induced DNA damage, fueled by NAMPT-derived NAD+, mediates skin inflammation through parthanatos cell death. Highlights NAMPT inhibition alleviates inflammation in zebrafish and human epidermis organoid models of psoriasis. NADPH oxidase-derived ROS mediates keratinocyte DNA damage and Parp1 overactivation. Inhibition of parthanatos cell death phenocopies the effects of NAMPT inhibition in zebrafish and human psoriasis models. NAMPT and PAR metabolism is altered in psoriasis patients.


Si is emerging as one of the most prospective anode materials for all-solid-state Li-ion batteries due to its extremely high theoretical capacity density of 4200 mAh g-1 and relatively negative potential for lithiation/delithiation. Towards its widespread use, controlling severe volume expansion/contraction during lithiation/delithiation is a challenge because it may cause cracking, fracture, and pulverization that negatively influence the cycle performance and rate capability of the cells [1]. Such mechanical event is induced by the change in the lattice structure due to the formation of LixSi and successive increasing/decreasing of Li content x in LixSi [2].
 Bimodal atomic force microscopy (AFM) offers quantitative mapping of nanoscale mechanical property, simultaneously with surface topography imaging [3]. Our group previously applied this technique to the cross-section of a composite electrode consist of active materials, binders, conductive additives, and deposited electrolyte solution and successfully demonstrated nanomechanical mapping [4]. Here, we develop an operando bimodal AFM system to track Young's modulus changes of electrode materials in an all-solid-state battery configuration during the lithiation and delithiation reactions in real-time.
 A cell in a Cu/Si/LLZT/In/Li configuration was fabricated as follows; a 3 µm-thick Si thin-film and a 100 nm-thick Cu layer were sputter-deposited on one side of Li6.6La3Zr1.6Ta0.4O12 (LLZT) solid electrolyte, an In layer was sputter-deposited on the other side of LLZT, the Cu/Si/LLZT/In sample was milled with an Ar-ion beam to yield a flat and smooth cross-section suitable for AFM analysis, and then a 50 µm-thick Li metal foil was combined with the pre-coated In thin layer. Operando nanomechanical mapping was performed by mounting the cross-section-exposed cell in the custom-made sample holder coupled with a potentiostat for bias applications, in an Ar-filled glove box to prevent any atmospheric influences.
 Electrochemical lithiation and delithiation were carried out within a potential window of 0.01-1.20 V vs. Li/Li+. Electrochemical characterization indicated that the capacities of the Si electrode for the first lithiation and delithiation are 3300 and 1833 mAh g-1, respectively. These capacities are equal to the formation of Li3.46Si after the first lithiation of the pristine Si and Li1.54Si after the successive delithiation from Li3.46Si. Throughout the lithiation, the averaged Young's modulus of Si electrode decreased due to the formation of LixSi and increase in the Li content x in LixSi. In the initial stage of lithiation, it drastically decreased because LixSi was formed by the lithiation of pristine Si. Then, it moderately decreased with increasing Li content x in LixSi. Unfortunately, the Young's modulus maps were only recorded until the formation of Li1.54Si because the successive delithiation was not completed possibly due to the phase transformation of crystalline LixSi to amorphous LixSi [5], which may cause a significant mechanical strain inside the thin film. The measured Young's modulus values were consistent with those obtained by first principle calculation [6]. Further details are given at the presentation.

This paper describes a remote training which supports the coaching of runner's form by applying wearable wireless sensors. The system provides a trainer with kinematic information about exercise behaviour of a trainee through monitoring the arm swing with the tri-axial accelerometer in real time. While a trainer can advise the improvement of body movement on a web browser, a trainee can receive the indication during running as a sound feedback. We have designed and implemented our proposal. From the result of an experiment, it was found that the system contributed to the stabilisation of the running form through trainer's appropriate advice.


The retail sector has strong impetus to overall economic growth as a significant driver of the growth of services sector, which contributes more than 50 per cent of GDP. It has strong backward and forward linkages with other sectors like agriculture and industry through stimulating demand for goods and through mass marketing, packaging, storage and transport. Moreover, it creates considerable direct and indirect employment in the economy. Also, the consumers have benefited in terms of wide range of products available in a market. The retail business in India is estimated at grow at 13 percent per annum from US$ 322 million in 2006-7 to US$ 590 billion in 2011–12 and expected to be US$ 700 billion in 2015–16. The unorganized sector is expected to grow at about 10 percent per annum from US$ 309 billion in 2006-7 to US$ 496 billion in 2011–12 and expected to be US$ 650 billion in 2015–16. Organized retail which now constitutes a small four percent of retail sector in 2006-7 is likely to grow at 45–50% per annum and quadruple its share of total retail trade to 16 percent by 2014–15. Retailing in India came with evolutionary patterns from grocery store to super market/malls. This sector was un-organized in the initial stage, and after that it is carried forward and now it is growing as supermarket and hypermarket. The paper depicts the main drivers of the retail revolution in India and how this revolution changes the buying behavior of the customer, increase in disposable income of the middle class, infrastructure development and changing customer choice. Organized Retailing is introduced in the last decade and has emerged as one of the sunrise industries in India. The survey intends to analyze the consumer behavior towards organized and unorganized retailing, their source of purchasing and the factors which influences their mall purchasing in India. The research paper intends to find out the consumer behavior towards organized (supermarkets/malls, hypermarkets, departmental stores etc) and unorganized (local grocery stores, weekly bazaars etc) retail stores in Delhi/NCR. The study focuses on the consumer's satisfaction level from organized retail stores as well as unorganized retail stores. This research paper is based on respondents who buy their product at organized and unorganized retail outlets. The study has tried to find out consumer behavior of respondents when they shop through organized and unorganized retail outlets. As a part of consumer behavior, their perceptions, motivation levels and demographic factors were studied. The study has also tried to study the reasons for preference of retail outlets and the attributes that consumers look for when they visit retail outlets.


The authors assume burst Alamouti coded STC CPM (MSK) modulation in MIMO channel as a particular example of nonlinear multichannel modulation (NMM). The NMM has multidimensional constellation waveforms. The major goal is to find suboptimal receiver signal preprocessing that could substantially reduce receiver decoding metric computation complexity with minor degradation of the STC performance. The author introduce linear waveform subspace projector reducing the dimensionality and thus the complexity of the receiver signal processing. The author analyzed the impact of the subspace projector on the code performance in terms of its rank, determinant (diversity and coding gain) and bit error rate. The author found an optimal subspace basis which does not reduce the rank of the code and which affects the determinant and bit error rate by the minimum possible amount.


Abstract : The objective of the study was to obtain information about the flow of chemically reacting air that has been heated in a vortex stabilized, high voltage, direct current arc and expanded to hypersonic speeds in a conical nozzle. The inviscid core of the axisymmetric flow in the supersonic section of the nozzle was theoretically analyzed by the method of characteristics for air in chemical and thermal equilibrium. Impact pressure, mass flux, and heat transfer profiles and nozzle-wall static pressures were obtained. Light emissions from the reacting stream were recorded spectroscopically.

For further developments of Si/Ge based hetero devices, very thin high-quality SiGe strain relaxed layers (virtual substrates) are highly required to provide high quality strained Si and Ge layers. For this purpose, we have been developing ion implantation technique, where relatively heavy ions such as Si, Ge and Ar are pre-implanted into Si substrates before growth of SiGe buffer layers [1]. The defects are introduced in the vicinity of the Si surface by the ion implantation and they are expected to work effectively as dislocation sources and enhance the relaxation of SiGe layers. Samples were fabricated in the following procedure. The ion implantation on a Si (001) substrate was carried out with various energies and doses, followed by annealing at 700oC for 10 min in N2 atmosphere for recrystalization. The end-of-range defects still remained underneath the Si surface even after this annealing process. After wet cleaning and surface H-termination, the substrate was loaded into a solid source molecular beam epitaxy (MBE) chamber and subjected to thermal cleaning at 700oC for 10 min. Subsequently, 100-nmthick Si0.8Ge0.2 layer was grown at 500 oC and finally annealing was performed at 900 oC for 30 min in N2 to promote the relaxation. Figure 1 shows (004) XRD rocking curves for the samples grown on Si-implanted and unimplanted Si substrates before and after annealing. Before annealing, both samples are found to be almost fully strained. Clear fringes reflect abruptness of hetero interfaces between Si substrates and SiGe layers. After annealing, on the other hand, the peaks shift to higher angles and the fringes disappear due to the strain relaxation. The degrees of relaxation obtained from the peak shifts are 75 and 20 % for the implanted and unimplanted samples, respectively, indicating that the strain relaxation is well enhanced by the ion implantation. Surface AFM images are shown in Fig. 2. For the unimplanted sample, a very clear and nonuniform crosshatch pattern is observed in spite of little relaxation. This roughness could be enhanced further when the relaxation proceeds with the thickness increase. For the implanted sample, on the other hand, smaller and uniform crosshatch pattern is seen in spite of the much larger relaxation. It is remarkable that rms roughness is 0.2 nm, which is comparable or less than CMP surfaces. Raman mapping measurements were next carried out to see the in-plane strain-field distribution as shown in Fig. 3. A crosshatch-like strain distribution is clearly observed for the unimplanted sample presumably due to a nonuniform misfit dislocation distribution. On the contrary, for the implanted samples, the strain distribution is found to be very uniform, indicating that the misfit dislocation generation takes place very uniformly due to the implantation-induced defects. Strained Si nMOSFET was fabricated on the 100nmthick Si0.83Ge 0.17 buffer layer grown on the Ar-implanted Si substrate. The effective mobility as a function of the effective field is shown in Fig. 4. It is found that the mobility enhancement over control Si is 60 % at 0.4 MV/cm. This enhancement factor is comparable to the reported values obtained utilizing much thicker SiGe graded buffer layers. It should be emphasized that more than 10 times thinner SiGe buffer layer made by ion implantation technique achieves mobility enhancement in the strained Si device. It can be, therefore, said that the ion implantation technique developed here is very promising for realization of high performance devices based on SiGe relaxed layers.

The polarized reflection spectra of four faces of adenine·HCl single crystals have been measured between 6000 and 1830 A. The faces which were examined included the naturally occurring (100), (001), and (102) planes plus the artificially prepared (104) face. Absorption spectra are derived from the corresponding reflectance curves via the Kramers‐Kronig transformation. Clear evidence for the presence of four transitions which are polarized in the molecular plane and are presumably π → π* in origin is observed. The effects of intermolecular interactions are considered within the dipole approximation, and a procedure is given for extracting free molecule transition moments from the crystal spectra. This treatment leads to a satisfactory accounting of the observed dichroic ratios and the observed k dependence of the factor group splittings and band shapes. Transition moment directions (measured contraclockwise from the C4–C5 axis) and oscillator strengths are evaluated to be as follows: I (λ ≃ 2730 A)−28°,...

A new study found that receipt of the live measles, mumps, and rubella (MMr) vaccine on schedule after vaccination for other common infections is associated with a lower rate of hospital admissions for any kind of infections, but particularly for lower respiratory tract infections. Besides protecting children against targeted diseases, childhood vaccines have also been shown to have non-specific beneficial effects that reduce illness and death from non-targeted diseases, especially in lowincome countries. The aim of the Danish study, recently published in the journal JAMA,1 was to examine whether such non-specific effects might also be important for children in highincome settings, like Denmark. The authors looked at whether live MMr vaccine was associated with lower rates of hospital admissions for infections among Danish children. The study included 495,987 children born 1997–2006. They were followed from ages 11 mo to 2 y. The recommended vaccination schedule was inactivated vaccine against diphtheria, tetanus, pertussis, polio, and Hemophilus influenzae type b (DTaP-iPV-Hib) administered at ages 3, 5, and 12 mo; and MMr at age 15 mo. The research team found that there were 56,889 hospital admissions for any type of infection among the children in the study. receiving the live MMr vaccine after the inactivated DTaP-iPV-Hib vaccine was associated with a lower rate of hospital admissions for any infection. The association was particularly strong for lower respiratory tract infections and for hospital stays of longer duration. children who received DTaP-iPV-Hib after MMr had a higher rate of infectious disease admission. The study authors conclude that timely vaccination in the recommended sequence could avert a considerable number of hospital admissions for any infection between ages 16 and 24 mo. in an accompanying editorial,2 Drs David Goldblatt from the Ucl institute of child Health and Great ormond street children's Hospital (london,UK) and elizabeth Miller of Public Health england (london, UK) discuss unexpected benefits of vaccination, such as the apparent effect of live vaccines (i.e., measles and BcG) on reducing mortality from infections other than measles or tuberculosis. looking at measles vaccination from the viewpoint of fighting and globally eliminating this viral disease, the world Health organization (wHo) has recently reported promising numbers. Annual measles deaths have reached historic lows, dropping 78% from > 562 000 in 2000 to 122 000 in 2012. During this time period, an estimated 13.8 million deaths have been prevented by measles vaccination, and surveillance data showed that reported cases declined 77% from 853 480 to 226 722. More details were recently published in the WHO Weekly Epidemiological Report.3 These promising numbers are a result of global routine measles immunization coverage holding steady at 84% and 145 countries having introduced a routine second dose of measles vaccine to ensure immunity and prevent outbreaks. in addition to routine immunization, 145 million children were vaccinated during mass campaigns against measles in 2012, and more than 1 billion since 2000, with the support of the Measles and rubella initiative. This initiative was launched in 2001 as a global partnership led by the American red cross, United Nations foundation, Us centers for Disease control and Prevention (cDc), UNicef and wHo. The Measles and rubella initiative aims to ensure that no child dies from measles or is born with congenital rubella syndrome, to reduce measles deaths by 95% by 2015, and to achieve measles and rubella elimination in at least five of six wHo regions by 2020.

Abstract Magnetoresistance The magnetoresistance of semiconducting Bi100-xSbx single crystals (x = 5.5 and 6.3 at % Sb) at T = 297, 77 and 63 K was measured in magnetic fields up to B = 15 T. In this region, the dependence of the magnetoresistance on the magnetic field strength exhibits a negative slope, which is characteristic for semiconductor-semimetal or semiconductor-quasimetal transitions, as previously observed by other authors in Bi-Sb alloys in the liquide He-temperature range. The influence of hydrostatic pressure (p ≦ 15 kbar) on the extrema of magnetoresistance oscillations at T = 77 and 63 K arising from the Shubnikov-de Haas effect has been examined. The results confirm the concept of approaching and mutually repelling L-point conductivity and valence bands. For the samples investigated, the energy gaps [Eg(x = 5.5) =6.94 meV and Eg(x = 6.3) = 7.64 meV] show pressure dependences of dE/dp= -1.16 · 10-6 eV/bar at 77 K and -1.39 · 10 -6 eV/bar at 63 K, respectively. Preparation of the samples, their characterization in terms of chemical microanalysis and dislocation densities as well as the method of applying high hydrostatic pressure are described in detail.


Nowadays, Metaverse is very popular around the world. People read a lot of news reports about the metaverse every day. In many people's minds, the metaverse may be the future of humanity. Most investors prefer to invest companies which have some relationship with Metaverse products. However, how metaverse would fully integrate into our lives is still unclear, and there are numerous proposed solutions in the market. In order to evaluate the feasibility of metaverse applications, we will focus on what Metaverse is, the existing Semi-Metaverse attempt, the existing Metaverse application and the Metaverse university that the CUHKSZ's students made in this paper. Besides, we will also talk about the potential risks that the Metaverse may bring. At the end, we illustrate what Metaverse need to prepare and improve in the future. If Metaverse can be realized in the future, it will bring infinite convenience to human life. However, it is still very difficult to fully realize Metaverse depending on today's science and technology.


Observable effects for the Lorentz invariance violation (LIV) at a low energy scale can also be investigated in double beta decay (DBD). For example, by comparing the theoretical predictions with a precise analysis of the summed energy spectra of electrons in $2\nu\beta\beta$ decay, one can constrain the $\mathring{a}_{of}^{(3)}$ coefficient that governs the time-like component of the Lorentz invariance violating operator that appears in the Standard Model extension theory. In this work, we perform calculations of the phase space factors and summed energy spectra of electrons as well as of their deviations due to LIV necessary in such experimental investigations. The Fermi functions needed in the calculation are built up with exact electron wave functions obtained by numerically solving the Dirac equation in a realistic Coulomb-type potential with the inclusion of the finite nuclear size and screening effects. We compared our results with those used in previous LIV investigations that were obtained with approximate (analytical) Fermi functions and found differences of up to $30\%$ for heavier nuclei. Our work includes eight experimentally interesting nuclei. Next, we estimate and discuss the uncertainties of our calculations associated with uncertainties in Q-values measurements and the differences raised from the inclusion of the kinematic terms in the formalism. Finally, we provide the ratio between the standard phase space factors and their LIV deviations and the energies where the LIV effects are expected to be maximal. We expect our study to be useful in the current LIV investigations in $2\nu\beta\beta$ decay and to lead to improved constraints on the $\mathring{a}_{of}^{(3)}$ coefficient.
