Enhancing Trilateration Localization by Adaptive Selecting Distances

If there is not coordinating data, the sensor parameter is of no value in the internet of things system. A promising approach to offer location parameter is to leverage a specific localization method. However, there exist some uncertain factors, which result in low accurate localization. Many research works are presented to improve localization accuracy or localization efficiency. As many of them did not consider the uncertainty effect and mechanism during localization computation, the improvement is not promising. For this problem, an enhanced trilateration localization is therefore presented to improve the localization accuracy, which is called improved trilateration localization through quality evaluating and adaptive selecting (IT-QEAS). We firstly assess the quality of distance measurement results. Then these anchor nodes with higher quality distance are optimizing selected to perform localization calculation. Lastly, high accuracy location results can be achieved. Experimental results of definite localization data demonstrate that the trilateration localization can be improved effectively.
Factors Leading to Effectiveness and Satisfaction in Civil Engineer Information Systems

Abstract : The Air Force Civil Engineer Support Agency (AFCESA) has developed information systems in support of civil engineer operations. Over the last decade, the number of systems has grown to support the breadth of civil engineer functions. At this time, numerous (900+) decentralized systems support civil engineer functions around the world. Due to budget constraints, AFCESA is transforming civil engineer business processes to leverage the workforce in an optimized fashion. In support of this transition, AFCESA is posturing to acquire new information systems in support of civil engineer business processes. To help AFCESA improve upon its suite of information systems development efforts it is important to evaluate the effectiveness of its current systems. This thesis develops a model based on cumulative research to assess information system effectiveness. The thesis evaluates 10 systems developed for the civil engineer community. Predictors of information system effectiveness are System Quality, Information Quality, and Service Quality. The study indicates that one system, GeoBase, is significantly better in all areas of information system effectiveness. It is recommended that future system development be fashioned after GeoBase.
Gradient-based Bit Encoding Optimization for Noise-Robust Binary Memristive Crossbar

Binary memristive crossbars have gained huge attention as an energy-efficient deep learning hardware accelerator. Nonetheless, they suffer from various noises due to the analog nature of the crossbars. To overcome such limitations, most previous works train weight parameters with noise data obtained from a crossbar. These methods are, however, ineffective because it is difficult to collect noise data in large-volume manufacturing environment where each crossbar has a large device/circuit level variation. Moreover, we argue that there is still room for improvement even though these methods somewhat improve accuracy. This paper explores a new perspective on mitigating crossbar noise in a more generalized way by manipulating input binary bit encoding rather than training the weight of networks with respect to noise data. We first mathematically show that the noise decreases as the number of binary bit encoding pulses increases when representing the same amount of information. In addition, we propose Gradient-based Bit Encoding Optimization (GBO) which optimizes a different number of pulses at each layer, based on our in-depth analysis that each layer has a different level of noise sensitivity. The proposed heterogeneous layer-wise bit encoding scheme achieves high noise robustness with low computational cost. Our experimental results on public benchmark datasets show that GBO improves the classification accuracy by ∼ 5–40% in severe noise scenarios.
Testing the Equality of Independent Alpha Coefficients Adjusted for Test Length

In comparing the merits of different item types or test formats, test developers are often called on to make a rigorous comparison of the internal consistency reliabilities of the scores from two competing tests. Such comparisons should be made for tests of equal length in terms of time demands and speededness. If the experimental instruments used in the field trials were not equal in length, estimates of the reliabilities of scores on equal-length tests can be obtained by applying the Spearman-Brown formula. In this article, the authors develop a statistical test for the hypothesis that [. alpha]1 [. minute] = [. alpha]2 [. minute], where [. alpha]i [. minute] is the extrapolated value of Cronbach’s alpha reliability for Test i. The test is shown to exercise tight control of Type I error.
A linearized inverse problem for the wave equation in a sphere

The problem of determining the velocity function c entering the wave equation was investigated by A.S. Blagoveshchenskii [1], V. G. Romanov [5, 6], M. M. Lavrent'ev, K. G. Reznitskaya, and V. G. Yakhno [3], and W. W. Symes [7]. This paper continues these investigations and is devoted to determining the function co(r) and the small additive term Ci(r, Θ,φ) on the velocity c(r,0,y? ). The conditional stability estimate is the main result of this paper. Let r0, Τ be given positive numbers. In the domain Ω = (0, r0) x S where S = |ί/(0,^? ) ν = (sin θ cos φ, sin θ sin φ> cos θ) \ is the unit sphere in 1R we consider the wave equation — = c(r θ &)Au (I) dt* \^V)^ W with conditions
Evaluation of salivary interleukin-6 in children with early childhood caries after treatment

Background: The role of cytokines as a marker in the oral inflammatory process in ECC has not been fully explored before and after full mouth rehabilitation. Aims: The aim of this study was to assess the level of salivary interleukin-6 (IL-6) in children with ECC and to compare its levels before and after comprehensive full mouth rehabilitation. Methods and Materials: Saliva samples were collected from children with ECC prior to dental treatment and 3-month post treatment. The salivary IL-6 levels were analyzed using the ELISA method. The gingival index was also timely recorded. Oral health awareness sessions were conducted for children and their parents at regular intervals during the 3-month study period. Statistical analysis used: Wilcoxon Signed Rank test compared the levels of salivary IL-6 while, the paired t test compared the values of gingival index before and after treatment. Results: The mean level of salivary IL-6 before and 3 months after treatment had reduced and this reduction was statistically significant (P< 0.000). The gingival index scores had also reduced significantly 3-months post treatment (P< 0.002). Conclusions: Children with ECC when completely rehabilitated and kept under frequent follow up, which includes reinforcement of oral hygiene measures and maintaining a low caries activity state, the level of inflammation (IL-6) can definitely be minimized and thereby improving the quality of life of affected children.
Dietary intake in hemodialysis patients does not reflect a heart healthy diet.

OBJECTIVE Cardiovascular disease is highly prevalent and has a major effect on morbidity and mortality in patients undergoing maintenance hemodialysis (MHD). Dietary factors that may contribute to cardiovascular disease have not been well studied in this population. We hypothesize that dietary intake in this population does not meet the guidelines for cardiovascular risk reduction. DESIGN A cross-sectional study was completed using the validated "Block Dialysis 1 Food Frequency Questionnaire" to assess dietary intake of MHD patients. SETTING AND PATIENTS A total of 70 patients undergoing MHD at our outpatient dialysis center completed the questionnaire under the supervision of a trained dietitian. The population consisted of 38 men and 32 women. MAIN OUTCOME MEASURE Dietary intake was the main outcome measure, with a focus on calories, soluble fiber, saturated fatty acid (SFA), unsaturated fatty acid intake (UFA), and protein. RESULTS The mean fiber intake was 10.77 (±5.87) g/day, and only 2 of 71 (2.9%) were in compliance with the recommended daily intake of >25 g/day. As percentage of total calories, of the 70 patients, 5 (7.1%) had a fat intake of <30%, 22 (31.4%) had SFA intake of <10%, 64 (91.4%) had a UFA of ≤30%, 22 (31.4%) had a protein-based diet of ≥15%, and 66 (94.3%) had a carbohydrate diet of <60%. CONCLUSIONS Most patients did not meet the dietary guidelines for reducing the risk of cardiovascular disease. Substituting UFA or soluble fiber for SFA improves low density lipoprotein (LDL) cholesterol levels without negative effects on other lipid parameters.
Markets for Technology

The changes in the technology market over the last few decades provide motivation for a broad investigation and raise several questions. This paper refers to the book, titled "Markets for Technology: Economics of Innovation and Corporate Strategy" by Arora et al. (MIT Press, Cambridge, Mass., (2001)). After reviewing most of the familiar evidence about licensing and other technology transactions, the authors present their best estimates of market size for this type of activity.
Méthodes de recherche arborescentes. Application à la résolution de problèmes d'ordonnancement et au calcul d'itinéraires multimodaux

Les travaux presentes dans ce document traitent de methodes arborescentes pour la resolution de problemes combinatoires d'optimisation ou de decision. Le premier chapitre presente les contributions que nous avons apportees pour les methodes de resolution dites " a divergences ". Ces contributions concernent les modes de comptage des divergences pour les problemes a variables discretes, le developpement d'une heuristique dynamique a ponderation de variables, ainsi que, dans un contexte d'optimisation, l'utilisation de bornes ou d'heuristiques pour la selection des points de divergences. Ces differentes contributions sont illustrees sur des problemes d'ordonnancement ou sur des problemes de satisfaction de contraintes. Le deuxieme chapitre traite de propagation de contraintes pour la resolution de problemes d'ordonnancement disjonctifs en presence de contraintes temporelles generalisees. Des extensions de methodes de propagation de contraintes efficaces dans ce contexte sont proposees et des applications a la resolution de differents problemes d'ordonnancement sont egalement presentees. Le troisieme chapitre s'interesse a un probleme de calcul d'itineraires point a point sur des reseaux de transport multi-modaux. La prise en compte de la multi-modalite fait surgir a la fois de nouvelles contraintes permettant d'exprimer si la sequence de modes d'un itineraire conduit ou non a une solution admissible, mais aussi de nouveaux objectifs comme la minimisation du nombre de changement de modes. Le probleme etudie (minimisation du temps de trajet et du nombre de transferts) est polynomial et differentes variantes basees sur le principe de l'algorithme de Dijkstra sont presentees et evaluees sur un cas reel.
CRZ1, a target of the calcineurin pathway in Candida albicans

Calcineurin is a major player in calcium‐dependent signal transduction pathways of eukaryotes. Calcineurin acts on transcription factors (e.g. CRZ1 in Saccharomyces cerevisiae) and governs the expression of genes in a species‐dependent fashion. In Candida albicans, the calcineurin pathway is involved in tolerance to antifungal agents, cation homeostasis and virulence. However, the components of the calcineurin pathway are still poorly investigated in this yeast species. Taking S. cerevisiae as a model to reconstitute this pathway, two CRZ1‐like genes, CRZ1 and CRZ2 (for calcineurin‐responsive zinc finger 1 and 2 genes), were found with C2H2 zinc finger domains. Only CRZ1 was able to restore the calcium hypersusceptibility of a S. cerevisiae crz1Δ mutant and to mediate calcium‐dependent gene expression in this yeast species. Several experiments showed that CRZ1 was dependent on calcineurin in C. albicans: (i) phenotypic analysis of a crz1Δ/Δ mutant showed impaired growth as compared with the wild type in the presence of cations (Ca2+, Mn2+) as does a mutant lacking calcineurin subunit A (cnaΔ/Δ) and (ii) a green fluorescent protein (GFP)–Crz1p fusion protein showed a calcium‐ and calcineurin‐dependent nuclear localization. To further analyse the relationship between calcineurin and CRZ1, a comprehensive analysis of calcineurin/Crz1p‐dependent gene expression following addition of Ca2+ (200 mM) was performed. Among the expression of 264 genes altered by at least twofold, the upregulation of 60 genes was dependent on both calcineurin and CRZ1. Interestingly, a motif [5′‐G(C/T)GGT‐3′] with similarity to the target sequence of Crz1p (GNGGCG/TCA) from S. cerevisiae was identified as a putative regulatory sequence in the upstream regions of these calcineurin/Crz1p‐dependent genes. However, additional experiments showed that calcineurin may have other targets in addition to CRZ1. First, CRZ1 was not involved in tolerance to antifungal agents (fluconazole, terbinafine) on the opposite to calcineurin. Second, CRZ1 was only moderately influencing virulence in a mice model of infection which is in sharp contrast to the strong avirulence of cnaΔ/Δ mutant in the same animal model. Even though this work establishes CRZ1 as a calcineurin target, further studies are needed to identify other calcineurin‐dependent elements in C. albicans.
Categorization Goals Modulate the Use of Natural Scene Statistics

Understanding natural scenes involves the contribution of bottom–up analysis and top–down modulatory processes. However, the interaction of these processes during the categorization of natural scenes is not well understood. In the current study, we approached this issue using ERPs and behavioral and computational data. We presented pictures of natural scenes and asked participants to categorize them in response to different questions (Is it an animal/vehicle? Is it indoors/outdoors? Are there one/two foreground elements? ). ERPs for target scenes requiring a “yes” response began to differ from those of nontarget scenes, beginning at 250 msec from picture onset, and this ERP difference was unmodulated by the categorization questions. Earlier ERPs showed category-specific differences (e.g., between animals and vehicles), which were associated with the processing of scene statistics. From 180 msec after scene onset, these category-specific ERP differences were modulated by the categorization question that was asked. Categorization goals do not modulate only later stages associated with target/nontarget decision but also earlier perceptual stages, which are involved in the processing of scene statistics.
Skeletal ryanodine receptor gene associated with chemical compositions of meat and physiochemical parameters of blood.

Objectives of the current study were to segregate single nucleotide polymorphism of the ryanodine receptor gene (RyR1) gene as well as to evaluate its effects on blood parameters and chemical composition traits of meat. For these, 90-American Yorkshire (AY), 85-American Landrace (AL) and 162- Australian unrelated commercial Yorkshire x Landrace (YL) pigs were genotyped for the locus C1843T (Arg615Cys) corresponding to alleles "N" and "n". In relation to the RyR1 polymorphism, a frequency of 0.09 was observed for the "n" allele in the YL breed but not in the AY and AL. Therefore, only the YL pigs were phenotyped for physiochemical properties and chemical compositions of meat. A significant association was found between genotypes and observed traits, assessed by 1 WBC30, WBC100, PLT30, DML, CPL, and PL with genotype NN being higher than Nn as well as by GLU60 and AshL (P<0.05) with NN being lower than Nn. The allele "N" showed great potential in the genetic improvement for health and metabolism in pigs.

Comparative Outcomes of Adults Hospitalized With Seasonal Influenza A or B Virus Infection: Application of the 7-Category Ordinal Scale

Abstract Background The objective of this study was to investigate the difference in disease severity between influenza A and B among hospitalized adults using a novel ordinal scale and existing clinical outcome end points. Methods A prospective, observational study was conducted over the 2016–2018 influenza seasons in a central hospital. The primary outcome was the rate of clinical improvement, defined as a decline of 2 categories from admission on a 7-category ordinal scale that ranges from 1 (discharged with normal activity) to 7 (death), or hospital discharge up to day 28. Results In total, 574 eligible patients were enrolled, including 369 (64.3%) influenza A cases and 205 (35.7%) influenza B cases. The proportion of patients with a worse ordinal scale at admission was higher in influenza A than influenza B (P = .0005). Clinical improvement up to 28 days occurred in 82.4% of patients with influenza A and 90.7% of patients with influenza B (P = .0067). The Cox model indicated that influenza B patients had a higher clinical improvement probability than influenza A cases (adjusted hazard ratio [HR], 1.266; 95% confidence interval [CI], 1.019–1.573; P = .0335). A similar pattern was observed in weaning oxygen supplement (adjusted HR, 1.285; 95% CI, 1.030–1.603; P = .0261). In-hospital mortality for influenza A was marginally higher than influenza B (11.4% vs 6.8%; P = .0782). Conclusions Our findings indicated that hospitalized patients with influenza A were more ill and had delayed clinical improvement compared with those with influenza B virus infection.
Letters to the Editor

The invited essay "The Critical Approach to Social Work" (JSWE, Fall 2002) aptly described the social work education from an evolutionary epistemology. In his analysis of social work education, Perkinson relies on a biological analogy. This analogy is then used to underscore how knowledge grows and develops in educational systems. Perkinson states, " [T]he knowledge and behaviors we create are always imperfect in some way mistaken, wrong, erroneous, inadequate" (p. 365). I would agree. Further, Perkinson leads the reader to believe that growth then comes from critical analysis and understandings. He states, "Criticism facilitates this growth" (p. 365). These points are well taken. Perkinson's knowledge of education is no doubt impressive. However, the lines become obscured when theory of education, which is discussed in this essay, meets the actual social work practice and education. Perkinson states, "Students are fallible creators who make trial conjectures and formulate trial skills and then eliminate the errors uncovered by criticism or critical selection" (p. 366). I would disagree with this point, and expand this disagreement in the following response. Social work students are often nontraditional. Social work students come to the academic arena with skills, knowledge, and wisdom. Traditional methods based on biological analogies of teaching do not universally apply to this group of students. Instead the focus of social work education should be on the student where they are, not from where we are as educators-on models of person-inenvironment and views of the system as sociocultural, with complex feedback loops which allow for the integration of information and knowledge. This is a more appropriate method of instructing the social work student if we are modeling the behaviors we would like our students to emulate. The training of social work students for the profession is embedded in the profession and in the modeling of behavior in accordance to the ethical guidelines of the profession. In the National Association of Social Workers Code of Ethics (1999), section 3.02(b) calls for social work educators to be "fair and respectful. " This standard underlies the concept of empowerment. An empowerment approach would allow individuals to express
Gastric pseudopolyposis: a new clinical manifestation of type A gastritis.

Three cases of type A gastritis associated with multiple polypoid lesions of the body of the stomach are presented. The endoscopic congo-red test showed the red to black color changes of the sprayed congo-red only on the top of the polypoid lesions. The endoscopic methylene-blue test revealed no dye absorption on the antral mucosa or on the top of the polypoid lesions, while the dye was absorbed on the flat mucosa surrounding the top of the polypoid lesions. Histological examinations revealed well-preserved oxyntic glands on the top of the polypoid lesions. The flat mucosa showed marked atrophy or intestinal metaplasia. There have been several reports of experimental models of type A gastritis, where chief and parietal cells decreased in considerable number. These findings and the experimental models suggest that the polypoid lesions resulted from atrophic changes of type A gastritis. The top of the polypoid lesions is the residual oxyntic glands. The lesions, therefore, should be called "gastric pseudopolyposis. " The spontaneous disappearance of the polypoid lesions seen in one case is thought to be a result of a further progression of the atrophic gastritis. A pronounced G-cell increase was noted in the antrum and lower body of the stomach. This is considered a secondary phenomenon following the marked reduction of acid secretion.
The Bible as a Graphic Novel: When the Word Becomes (Affecting) Image

A twenty-something woman sitting next to me on a plane thumbs distractedly through a fashion-and-lifestyle magazine . called Becoming.

Cover lines surround her in bright green and blue type on a purple background: “13 STORIES OF SURVIVAL; THE MUST-HAVE for your wardrobe; LOVE: WHAT IS IT? And How to Find it. ” . There are columns about how to lose weight, how to balance work and play, how to find and keep the right man . But then I notice other, not-so-standard elements: boxed features and callouts and columns about “Bible Women” and “Bible Stuff to Know,” and longer articles with titles like “Matthew,” “Romans,” and “Revelation” .
