Experimental Study of Single-Transmitter-Based Precise Indoor Positioning System

A single-transmitter-based positioning system using an antenna array has been designed and developed to minimize the number of transmitters needed for environments where satellite-based navigation systems are unavailable. One of its suitable applications is for indoor navigation. The user receives the signals from the antenna array and calculates the position using the carrier-phase measurements. A key feature of the system is that the number of cycle ambiguity candidates is geometrically bounded. If the length of the antenna baseline is smaller than half the wavelength, the ambiguity resolution process is unnecessary. To improve the positioning performance for practical use, the antenna baseline must be enlarged. Even in this case, the cycle ambiguity resolution issue can be resolved fast and accurately. For instance, there are only nine candidates according to the setting of the study. To investigate the performance of the system, experiments for a dynamic rover using multiple “pseudolites,” pseudo-satellite transmitters, were conducted. In addition, low-cost inertial measurement unit (IMU) sensors were combined to investigate the improved positioning accuracy. Experimental results showed that positioning root-mean-square errors were 18 cm and 25 cm with IMU and without IMU, respectively, at the scale of a conventional meeting room. All integer-cycle ambiguities were solved accurately during the experiments, and more than 93% were resolved within 5 s.
Deep Network-Based Feature Selection for Imaging Genetics: Application to Identifying Biomarkers for Parkinson's Disease

Imaging genetics is a methodology for discovering associations between imaging and genetic variables. Many studies adopted sparse models such as sparse canonical correlation analysis (SCCA) for imaging genetics. These methods are limited to modeling the linear imaging genetics relationship and cannot capture the non-linear high-level relationship between the explored variables. Deep learning approaches are underexplored in imaging genetics, compared to their great successes in many other biomedical domains such as image segmentation and disease classification. In this work, we proposed a deep learning model to select genetic features that can explain the imaging features well. Our empirical study on simulated and real datasets demonstrated that our method outperformed the widely used SCCA method and was able to select important genetic features in a robust fashion. These promising results indicate our deep learning model has the potential to reveal new biomarkers to improve mechanistic understanding of the studied brain disorders.
the Asymptomatic Stage of Infection Immune Response That Appears Prevalent in Induce a Predominant Th1-Type Adaptive HIV-1 Tat Addresses Dendritic Cells to

Tat is an early regulatory protein that plays a major role in human HIV-1 replication and AIDS pathogenesis, and therefore, it represents a key target for the host immune response. In natural infection, however, Abs against Tat are produced only by a small fraction ( (cid:1) 20%) of asymptomatic individuals and are rarely seen in progressors, suggesting that Tat may possess properties diverting the adaptive immunity from generating humoral responses. Here we show that a Th1-type T cell response against Tat is predominant over a Th2-type B cell response in natural HIV-1 infection. This is likely due to the capability of Tat to selectively target and very efﬁciently enter CD1a-expressing monocyte-derived dendritic cells (MDDC), which represent a primary target for the recognition and response to virus Ag. Upon cellular uptake, Tat induces MDDC maturation and Th1-associated cytokines and (cid:1) -chemokines production and polarizes the immune response in vitro to the Th1 pattern through the transcriptional activation of TNF- (cid:2) gene expression. This requires the full conservation of Tat transactivation activity since neither MDDC maturation nor TNF- (cid:2) production are found with either an oxidized Tat, which does not enter MDDC, or with a Tat protein mutated in the cysteine-rich region (cys22 Tat), which enters MDDC A two-tailed t test was used for the statistical treatment of data gathered from experiments with MDDC.
Recombination Analysis in Cadmium Telluride Photovoltaic Solar Cells With Photoluminescence Spectroscopy

We used photoluminescence (PL) spectroscopy to study recombination in polycrystalline CdS/CdTe photovoltaic solar cells with open-circuit voltages in the range of 0.899-0.895 V. From PL emission spectra, we identified defects with an activation energy of 0.11-0.12 eV in the junction and back-contact regions. At <;100 K, lifetimes in devices were similar to those in single crystals and ranged from 300-400 ns. Strong lifetime temperature dependence at 100-300 K suggests the presence of a relatively shallow recombination center. Therefore, it is possible that in CdTe solar cells, lifetime is limited by relatively shallow defects.
Correlation of Staphylococcus aureus icaADBCGenotype and Biofilm Expression Phenotype

We read with interest the article of Arciola et al. ([1][1]) on the presence of icaA and icaD genes in Staphylococcus aureus and S. epidermidis isolates from catheter-associated infections and its correlation with a slime-positive phenotype detected with Congo red agar. These are the organisms most
Stress in Elite Sports Coaching: Identifying Stressors

This paper presents the first in a series of studies exploring coaches’ experiences of stress within the unique culture of world class sport. The purpose of this study was to gain an in-depth account of the stressors encountered by elite coaches in the United Kingdom. Six male and six female coaches with international experience were interviewed. Transcribed interviews were inductively content analyzed by three independent researchers. Ten higher-order themes emerged, demonstrating that coaches experienced a wide range of stressors (e.g., conflict, pressure and expectation, athlete concerns, competition preparation, isolation). Conflict within the organization emerged as a key theme, indicating that communication skills might be important in helping coaches function effectively as part of a wider organizational team. Findings also highlight the importance of psychological skills training for coaches to help them cope with the diverse demands of world class coaching.
Cochlear implantation as a durable tinnitus treatment in single-sided deafness

Abstract Introduction Severe tinnitus can seriously impair patients in their activities in daily life and reduce their quality of life. The aims of this prospective clinical study were to assess the long-term effects of cochlear implantation (CI) on tinnitus in patients with single-sided deafness and ipsilateral incapacitating tinnitus, and to investigate whether CI could treat various types of tinnitus. Materials and methods Twenty-six subjects with unilateral severe-to-profound sensorineural hearing loss received a CI. Patients suffered from severe tinnitus greater than 6/10 on a visual analogue scale (VAS) due to unilateral deafness. Assessment consisted of a tinnitus analysis including determination of tinnitus type, frequency, and loudness. A tinnitus questionnaire (TQ) measured tinnitus distress. VAS and TQ were administered pre-implantation and post-implantation. Results All 26 patients reported a subjective benefit from CI. Tinnitus loudness reduced significantly after CI from 8.6 to 2.2 on the VAS (scale: 0–10). The TQ total score decreased significantly and the mean tinnitus degree decreased from severe to mild. No differences were observed between patients with pure-tone tinnitus, narrow band noise tinnitus, or polyphonic tinnitus. The degree of tinnitus loudness reduction remained stable after CI. Conclusions CI can successfully be used as treatment of severe tinnitus in patients with single-sided deafness and is equally effective for pure tone, narrow band noise, and polyphonic tinnitus. Long-term results show that implantation provides durable tinnitus relief in these patients. These results support the hypothesis that physiopathological mechanisms after peripheral deafferentation are reversible when hearing is restored. Single-sided deafness accompanied by severe tinnitus is a new indication for CI.
Distribution of micro-organisms along a transect in the South-East Pacific Ocean (BIOSOPE cruise) using epifluorescence microscopy

Abstract. The distribution of selected groups of micro-organisms was analyzed along a South-East Pacific Ocean transect sampled during the BIOSOPE cruise in 2004. The transect could be divided into four regions of contrasted trophic status: a High Nutrient Low Chlorophyll (HNLC) region (mesotrophic) near the equator, the South-East Pacific Ocean gyre (hyper-oligotrophic), a transition region between the gyre and the coast of South America (moderately oligotrophic), and the Chile upwelling (eutrophic). The abundance of phycoerythrin containing picocyanobacteria (PE picocyanobacteria), autotrophic and heterotrophic eukaryotes (classified into different size ranges), dinoflagellates, and ciliates was determined by epifluorescence microscopy after DAPI staining. Despite some apparent loss of cells due to sample storage, distribution patterns were broadly similar to those obtained by flow cytometry for PE picocyanobacteria and picoeukaryotes. All populations reached a maximum in the Chile upwelling and a minimum near the centre of the gyre. The maximum abundance of PE picocyanobacteria was 70 103 cell mL−1. Abundance of autotrophic eukaryotes and dinoflagellates reached 24.5 103 and 20 cell mL−1, respectively. We observed a shift in the size distribution of autotrophic eukaryotes from 2–5 μm in eutrophic and mesotrophic regions to less than 2 μm in the central region. The contribution of autotrophic eukaryotes to total eukaryotes was the lowest in the central gyre. Maximum concentration of ciliates (18 cell mL−1) also occurred in the Chile upwelling, but, in contrast to the other groups, their abundance was very low in the HNLC zone and near the Marquesas Islands. Two key findings of this work that could not have been observed with other techniques are the high percentage of PE picocyanobacteria forming colonies in the HLNC region and the observation of numerous dinoflagellates with bright green autofluorescence.
Generalized Distillation Framework for Speaker Normalization

Generalized distillation framework has been shown to be effective in speech enhancement in the past. We extend this idea to speaker normalization without any explicit adaptation data in this paper. In the generalized distillation framework, we assume the presence of some “privileged” information to guide the training process in addition to the training data. In the proposed approach, the privileged information is obtained from a “teacher” model, trained on speaker-normalized FMLLR features. The “student” model is trained on un-normalized filterbank features and uses teacher’s supervision for cross-entropy training. The proposed distillation method does not need first pass decode information during testing and imposes no constraints on the duration of the test data for computing speakerspecific transforms unlike in FMLLR or i-vector. Experiments done on Switchboard and AMI corpus show that the generalized distillation framework shows improvement over un-normalized features with or without i-vectors.
Molybdenum accumulation and storage in Klebsiella pneumoniae and Azotobacter vinelandii

In Klebsiella pneumoniae, Mo accumulation appeared to be coregulated with nitrogenase synthesis. O2 and NH+4, which repressed nitrogenase synthesis, also prevented Mo accumulation. In Azotobacter vinelandii, Mo accumulation did not appear to be regulated Mo was accumulated to levels much higher than those seen in K. pneumoniae even when nitrogenase synthesis was repressed. Accumulated Mo was bound mainly to a Mo storage protein, and it could act as a supply for the Mo needed in component I synthesis when extracellular Mo had been exhausted. When A. vinelandii was grown in the presence of WO2-(4) rather than MoO2-(4), it synthesized a W-containing analog of the Mo storage protein. The Mo storage protein was purified from both NH+4 and N2-grown cells of A. vinelandii and found to be a tetramer of two pairs of different subunits binding a minimum of 15 atoms of Mo per tetramer.
On-the-Fly Mapping for Synthesizing Dynamic Domino Circuits

In recent times, the usage of Domino logic in design of high performance circuits is increasing. In addition to its high performance advantage, the Domino logic style also offers flexibility in designing individual cells. Flexible height and width of cells gives the designer an advantage to realize a large variety of functions. This gives a scope for library free mapping. In this work, we present an approach for mapping a Domino logic circuit using on-the-fly technique. First, we present a node mapping algorithm which maps a given Domino logic net list using on-the-fly technique. Next, using an Equivalence Table, we re-order the cells along the critical path of the circuit for delay and area improvement. Finally, we find an optimum re-ordering set which can obtain maximum delay and area savings. We have tested the efficacy of our approach with a set of standard benchmark circuits. Our proposed mapping approach called Delay Area Aware Mapping (DAAM) obtained 21% improvement in area and 17% improvement in delay compared to the existing work.
The Joint Role of Locus of Control and Perceived Financial Need in Job Search

Guided by economic rational choice theory and the behavioral-coping literature, the present study examined contrasting perspectives of the role of job-search locus of control (JSLOC) and perceived financial need in predicting job-search intensity. Data were collected in two independent studies in the Netherlands and in the United States, both using a two-wave longitudinal design. Results from both studies suggested that job seekers with external JSLOC and high perceived financial need engaged in more intense search behavior to compensate for anticipated difficulties in finding employment. Findings suggested that stress may mediate this relation, and may play a positive role in the job-search process.

Ambulatory ventricular arrhythmias in patients with heart failure do not specifically predict an increased risk of sudden death. PROMISE (Prospective Randomized Milrinone Survival Evaluation) Investigators.

BACKGROUND Ventricular arrhythmias are a frequent finding in congestive heart failure (CHF) patients and a cause of concern for physicians caring for them. Previous studies have reached conflicting conclusions regarding the importance of ventricular arrhythmias as predictors of sudden death in patients with CHF. This study examined the independent predictive value of ventricular arrhythmias for sudden death and all-cause mortality in PROMISE (Prospective Randomized Milrinone Survival Evaluation). METHODS AND RESULTS Ventricular arrhythmias were analyzed and quantified by use of prespecified criteria on baseline ambulatory ECGs from 1080 patients with New York Heart Association (NYHA) class III/IV symptoms and a left ventricular ejection fraction </=35% enrolled in PROMISE. The relationship of ventricular arrhythmias and other clinical parameters to overall mortality and sudden death classified by an independent, blinded mortality committee was determined. There were 290 deaths, of which 139 were classified as sudden. Of the several measures of ventricular ectopy that were univariate predictors, the frequency of nonsustained ventricular tachycardia (NSVT) was the most powerful predictor and remained a significant independent predictor when included with other clinical variables in multivariate models of both sudden death mortality and non-sudden death mortality. However, multiple logistic analysis with models including the clinical variables with and without the NSVT variable demonstrated that the frequency of NSVT did not add significant information beyond the clinical variables. CONCLUSIONS This study demonstrates that ventricular arrhythmias do not specifically predict sudden death in patients with moderate-to-severe heart failure. Thus, the finding of asymptomatic NSVT on ambulatory ECG does not identify specific candidates for antiarrhythmic or device therapy.
Solitary breast papilloma: comparison of mammographic, galactographic, and pathologic findings.

OBJECTIVE Our purpose was to determine the mammographic/galactographic features of solitary breast papillomas and to correlate these features with the pathologic findings. MATERIALS AND METHODS Retrospective review of pathology files revealed 72 women in whom breast biopsy reports described a solitary papilloma. All patients with additional pathologic abnormalities were excluded from this study. Patients meeting the pathologic criteria and for whom mammograms, galactograms, or both were available and had been obtained within 6 months before biopsy were included. Twenty-four women met these criteria and form the basis of this study. Presenting clinical signs and symptoms were reviewed. Abnormal mammographic/galactographic findings were correlated with pathologic features. RESULTS Nipple discharge was present in 21 (88%) of 24 patients, two (8%) of 24 patients had abnormal findings on screening mammography, and one patient had a palpable mass that was visible on mammograms. Eight (42%) of 19 mammograms had abnormal findings, including dilated duct(s) in five cases (26%), nodules in two cases (11%), and microcalcifications in one case (5%). All technically adequate galactograms (13/15) had abnormal findings, with 12 (92%) of 13 showing an intraluminal filling defect. The other technically adequate galactogram (8%) showed only a solitary obstructed duct. Ductal dilatation was greatest at or central to the papilloma on 12 (92%) of 13 galactograms. Imaging features correlated well with the histologic findings. CONCLUSION Patients with solitary papillomas most commonly have nipple discharge, normal mammographic findings, and a galactographic filling defect. Galactography is useful for localizing papillomas.
Factors in College Students' Drinking

Associations of age, membership in a sorority or fraternity, and whether a family member had an alcohol-related problem with the number of alcohol-related problem behaviors were examined by asking 160 people on campuses and one Board of Education in the northeastern United States to complete anonymously a 17-item questionnaire reporting the number of drinking-related problem behaviors. A 2×2×3 factorial analysis of variance with unequal ns yielded significance for age, type of family membership, and the interaction between age and membership in a sorority or fraternity. Younger subjects reported more alcohol-related drinking behaviors as did those with members of their family having drinking problems. Finally, younger members of a Greek organization reported the greatest number of problem behaviors.
The “Alzheimer's Type” Profile of Semantic Clustering in Amnestic Mild Cognitive Impairment

Abstract Impairments in learning and recall have been well established in amnestic mild cognitive impairment (aMCI). However, a relative dearth of studies has examined the profiles of memory strategy use in persons with aMCI relative to those with Alzheimer's disease (AD). Participants with aMCI, nonamnestic MCI, AD, and healthy older adults were administered the California Verbal Learning Test-II (CVLT-II). Measures of semantic clustering and recall were obtained across learning and delayed recall trials. In addition, we investigated whether deficits in semantic clustering were related to progression from healthy aging to aMCI and from aMCI to AD. The aMCI group displayed similar semantic clustering performance as the AD participants, whereas the AD group showed greater impairments on recall relative to the aMCI participants. Control participants who progressed to aMCI showed reduced semantic clustering at the short delay at baseline compared to individuals who remained diagnostically stable across follow-up visits. These findings show that the ability to engage in an effective memory strategy is compromised in aMCI, before AD has developed, suggesting that disruptions in semantic networks are an early marker of the disease.

Schematic drawings of facial expressions for emotion recognition and interpretation by preschool-aged children.

Schematic drawings of facial expressions were evaluated as a possible assessment tool for research on emotion recognition and interpretation involving young children. A subset of Ekman and Friesen's (1976) Pictures of Facial Affect was used as the standard for comparison. Preschool children (N = 138) were shown drawing and photographs in two context conditions for six emotions (anger, disgust, fear, happiness, sadness, and surprise). The overall correlation between accuracy for the photographs and drawings was . 677. A significant difference was found for the stimulus condition (photographs vs. drawings) but not for the administration condition (label-based vs. context-based). Children were significantly more accurate in interpreting drawings than photographs and tended to be more accurate in identifying facial expressions in the label-based administration condition for both photographs and drawings than in the context-based administration condition.
The role of lymphocyte function‐associated antigen 1 (LFA‐1) in the adherence of T lymphocytes to B lymphocytes

The functional role of the LFA‐1 molecule in the interaction between helper T lymphocytes and B lymphocytes was investigated using lymphocytes from patients with leukocyte adhesion deficiency, an inherited immunodeficiency characterized by a defective leukocyte expression of the LFA‐1, Mac‐1 (CR3) and p150,95 molecules. The ability of LFA‐1− T lymphocytes to provide antigen‐specific help for HLA−identical LFA‐1+ B lymphocytes was reduced while their antigen‐specific activation was normal. Antigen‐independent conjugate formation between resting, nonactivated LFA–1− T lymphocytes and LFA‐1+ B lymphocytes was impaired while LFA‐1−B lymphocytes bound LFA‐1+ T lymphocytes normally. Conjugate formation of activated LFA‐1− T lymphocytes was mostly mediated by the CD2‐LFA‐3 adhesion pathway while the ICAM‐1 molecule, a ligand of LFA‐1, had no function. These results demonstrate that LFA‐1 plays a major role in the cognate interaction between helper T lymphocytes and B lymphocytes that cannot be mediated instead by CD2 or other molecules on resting T lymphocytes.
Case Study of a Schizophrenic Patient during Social Skills Training in a Forensic Psychiatry Ward

A schizophrenic patient's behaviour was monitored over 12 weeks using the Assessment Schedule and Adult Training Instrument, the patient's self-reports of his symptoms of anxiety, scores on the Social Behaviour Schedule, and the frequency of nocturnal enuresis. Contrary to expectations, the patient's functioning deteriorated generally, with the exception that the trend of deteriorating behaviour, as assessed by hospital staff, appeared to have slowed down during a period involving activities out of the ward.
