A study of the physical characteristics of vibration-induced fretting corrosion

The objective of this work is to develop a greater understanding of the mechanisms controlling fretting under various vibration conditions. This information is intended to provide a basis for understanding and reducing this potential problem in automotive connectors. Toward this end, an experimental study of connector samples under multifrequency vibration has been conducted. The primary connector being investigated is a single row PC-type connector. A secondary specimen tested is a single row automotive connector
Efficiently Summarising Event Sequences with Rich Interleaving Patterns

Discovering the key structure of a database is one of the main goals of data mining. In pattern set mining we do so by discovering a small set of patterns that together describe the data well. The richer the class of patterns we consider, and the more powerful our description language, the better we will be able to summarise the data. In this paper we propose \ourmethod, a novel greedy MDL-based method for summarising sequential data using rich patterns that are allowed to interleave. Experiments show \ourmethod is orders of magnitude faster than the state of the art, results in better models, as well as discovers meaningful semantics in the form patterns that identify multiple choices of values.
Direct modulation characteristics of microdisk lasers with InGaAs/GaAs quantum well-dots

GaAs-based microdisk lasers with an active region representing a dense array of indium-rich islands (InGaAs quantum well-dots) were studied using direct small-signal modulation. We demonstrate that using dense arrays of InGaAs quantum well-dots enables uncooled high-frequency applications with a GHz-range bandwidth for microdisk lasers. A maximum 3 dB modulation frequency of 5.9 GHz was found in the microdisk with a radius of 13.5 μm operating without a heatsink for cooling. A modulation current efficiency factor of 1.5 GHz/mA1/2 was estimated.
The party choice set and satisfaction with democracy

Abstract A well-functioning democracy requires citizens’ support for its political institutions and procedures. While scholars have previously studied the role of contextual factors for explaining satisfaction with democracy, a rigorous focus on how the party choice set affects how satisfied citizens are with democracy is largely absent from the literature. This neglect of the impact of parties is surprising, given their central position within modern, representative democracies. In this article, a comprehensive and comparative analysis of the impact of party systems on citizens’ satisfaction with democracy is presented. Use is made of the combined data of the first four modules of the Comparative Study of Electoral Systems project and various measures of the party system are used to capture different aspects of the party choice set: the number of parties, their polarisation, and the congruence between public opinion and the party offer. In contrast to expectations, only scant evidence is found that having a wider choice increases citizens’ satisfaction with democracy.
Can Attachment Style and Temperament Predict Personality Organization

Otto Kernberg (1967) developed a psychoanalytic theory of personality organization in which he posited that all individuals operate on one of three levels of personality organization: neurotic, borderline, or psychotic. His theory was developmental in nature and based on the idea that our earliest experiences establish unconscious interpersonal patterns that persist throughout life. The current study examined whether attachment style (anxious or avoidant) and factors of temperament (negative affect, effortful control) would predict personality organization. In particular, we examined identity diffusion and use of primitive defenses as markers of personality functioning. Results revealed that anxious attachment, negative affect, and effortful control significantly predicted identity diffusion and use of primitive defenses. The clinical implications for these findings as well as potential future research directions are discussed.
Collegiality vs role models: gendered discourses and the ‘glass escalator’ in English primary schools

ABSTRACT Attempting to encourage and retain male primary school teachers can lead to the ‘glass escalator’ phenomenon, the fast-tracked advancement that men receive in gender-atypical work. Currently, in primary schools, males are disproportionately represented in management positions making up 35% of senior staff, while conversely only making up 15% of the general teaching staff. This paper presents one main theme from current doctoral research exploring how the ‘glass escalator’ operates in English primary schools, presenting findings on gendered discourses on the role of ‘promotion’ for teachers. The identification of two conflicting views demonstrates a disparity between internal teaching pedagogies and external societal opinions upholding the ‘glass escalator’ phenomenon.

Quality of life and common psychological problems profile in a large sample of manufacturing employees in a developing country: an association analysis using latent class regression

ABSTRACT Background and objective: Quality of Life (QoL) indicates individual’s perception of the physical, psychological and social aspects of health. To the best of our knowledge, there is no study that examined the association of QoL with composite measure of common psychological problems i.e. anxiety, depression and psychological distress in manufacturing employees. This study aimed to investigate the association of QoL with common psychological problems profile in manufacturing employees. Material and methods: This cross-sectional study was conducted among 3063 employees of “E” Steel Company (ESCO). Psychological distress, anxiety and depression were assessed by self-administered 12-item general health questionnaire (GHQ-12) and hospital anxiety and depression scale (HADS). Euro-QoL five dimensions questionnaire (EQ-5D) was used to assess the QoL. Latent class analysis (LCA) and latent class regression (LCR) were used for analyzing data. Results: LCA identified two classes of participants: low QoL (20%) and high QoL (80%). LCR, after adjusting for the effects of confounding variables including demographic, life style and job-related variables, showed that the higher scores of psychological problems profile was significantly associated with increased odds of being in poor QoL class; (OR: 6.03, 95% CI: 3.76,9.69). Conclusion: In conclusion, higher scores of psychological problems profile are positively associated with poor QoL. QoL can be improved among manufacturing employees through conducting screening programs for identifying affective individuals and implementing health promoting interventions aiming to reduce psychological problems impacts and finally productivity of working force.
Deep Intermediate Representation and In-Set Voting Scheme for Multiple-Beat Electrocardiogram Classification

Electrocardiogram (ECG) analysis based on computer-aided diagnostic systems plays an important role in reducing the high mortality rate among cardiac patients, but this issue undergoes the challenges from complicated variations of the data. This paper conducts a pioneering research on a new branch of ECG analysis to recognize cardiovascular diseases: multiple-beat ECG classification. In the research, this paper proposes a novel approach that comprises two components, Deep Intermediate Representation (DIR) and In-Set Voting Scheme (ISVS), for representation and classification, respectively. By combining feature learning and selection, DIR can overcome the subjectivity of feature design that fully relies on human empirical knowledge, so that the discrimination and the generalization abilities are well balanced. In the feature space, ISVS can avoid the biased judgment caused by the noisy and anomalous samples of each set by means of committee voting and majority decision, which overturns the current belief in minority-based strategies for set-based discriminative measure. The effectiveness, efficiency, and adaptability of the proposed method have been fully demonstrated via theoretical analysis and experimental validation.

A Prospective Study on the Efficacy and Safety of Tamsulosin in the Treatment of Benign Prostatic Hyperplasia

INTRODUCTION Benign prostatic hyperplasia (BPH) is a pathologic disorder that develops in response to the action of dihydrotestosterone on the aging prostate and to changes in stromal and epithelial cells in this exocrine gland [1]. It is associated with unregulated proliferation of connective tissue, smooth muscle and glandular epithelium within the prostatic transition zone [2]. Prevalence of BPH rises markedly with age. Autopsy studies have observed a histological prevalence of 8%, 50% and 80% in the 4th, 6th and 9th decades of life, respectively [3]. Its clinical description includes lower Urinary tract symptoms(LUTS) present in approximately 3 out of 4 men after age 70 [4]. Treatment of BPH is directed at improving patients symptoms and Quality of life (QOL) [5]. The management of Benign Prostatic Hyperplasia (BPH) is now focused on non-invasovetherapy [6]. Treatment for BPH include watchful waiting for mild LUTS, pharmacological therapies (α1adrenoreceptor antagonists and/or 5 α-reductase inhibitors)for moderate to severe LUTS,and surgery for severe LUTS. Widespread α1adrenoreceptor antagonists are the first Line medical therapy for treating Lower Urinary Tract Symptoms due to BPH whichinhibit prostatic smooth muscle contraction. Tamsulosin is an antagonist of alpha1A adrenoceptors in the prostate, exhibits selectivity for alpha1 receptor with relatively no effect on the blood pressure.The purpose of the study is to analyse the efficacy of Tamsulosin in the treatment of benign prostatic hyperplasia The Study uses IPSS for determining the severity and Quality of Life. It is also measured before, 48hrs and after therapy and efficacy of Tamsulosin using Uroflowmetric Parameters as well as side-effects were also measured.
The effect of APOE genotype and streamline density volume, on hippocampal CA1 down-regulation: a real-time fMRI virtual reality neurofeedback study

Hippocampal hyperactivity is a precursor of Alzheimer’s disease and more prominent in APOE-ε4 carriers. It is therefore important to investigate the processes of hippocampal self-regulation, to monitor therapeutic efficacy of preclinical interventions. We have developed a closed-loop, virtual reality neurofeedback paradigm for real-time fMRI, that provides a standardized method for quantifying processes of hippocampal self-regulation. We acquired multi-modal neuroimaging data from a sample of 53 cognitively unimpaired subjects at risk for AD and applied standard methods of structural and functional connectomics. The analyses reveal significant negative associations between hippocampal CA1 down-regulation performance and APOE-ε4 alleles, as well as hippocampal streamline density volume. Better memory performance was associated with increased, bilateral hippocampal functional connectivity during the neurofeedback task. These are the first results to link neurofeedback performance to a genetic risk factor and structural connectivity. Further, these are the first evidence that functional cohesion between the hippocampi can reflect subtle differences in memory function, in cognitively unimpaired individuals at risk for AD. We provide a novel method to assess hippocampal function in preclinical AD, and propose it can be used to derive proxies for neural reserve. Highlights APOE-ε4 alleles impact hippocampal down-regulation neurofeedback performance. Hippocampal streamline density volume is associated with decreased hippocampal down-regulation performance. Bilaterally cohesive hippocampal activity is associated with better memory performance. We provide a novel paradigm to investigate self-regulation and brain function.
Improvement of SET variability in TaOx based resistive RAM devices

Improvement or at least control of variability is one of the key challenges for Redox based resistive switching memory technology. In this paper, we investigate the impact of a serial resistor as a voltage divider on the SET variability in Pt/Ta2O5/Ta/Pt nano crossbar devices. A partial RESET in a competing complementary switching (CS) mode is identified as a possible failure mechanism of bipolar switching SET in our devices. Due to a voltage divider effect, serial resistance value shows unequal impact on switching voltages of both modes which allows for a selective suppression of the CS mode. The impact of voltage divider on SET variability is demonstrated. A combination of appropriate write voltage and serial resistance allows for a significant improvement of the SET variability.
Bacteriological and immunological studies on some bacterial pathogens incriminated in bovine Mastitis

In this study a total of 1200 quarter milk samples were selected from 300 cows from different localities at El-Kaluobia governorate. The bacteriological examination revealed that a total of 125 isolates from clinical and subclinical mastitic milk samples of which 57 S.aureus isolates were isolated from both mastitic milk . with incidence of 45.6% of total isolates, 28 E.coli with 22.4%, 13 S.agalactia with 10.4%, 9 S. dysgalactia with 7.2%, 7 isolates of both S.uberis & coagulase negative staph (5.6%), 3 Klebsiella sp with 2.4% and 1 Pseudomonas sp with 0.8%. Mean titer of anti S aureus specific IgA was higher in milk of subclinical mastitic cases (1:845) than clinical one(1:290), while mean titer in milk of clinical and subclinical mastitic cases much higher than in serum of clinical(1:54)and subclinical (1:41), while mean titer of anti S. aureus specific IgM and IgG was much higher in serum of clinical(1:1382 , 1:868 for IgM&1:1267 , 1:634 for IgG ) than milk of clinical and subclinical mastitic cases (1:111 , 1: 53 for IgM& 1: 302 , 1: 206 for IgG). Results of sensitivity tests of S.aureus against different antibiotic discs revealed that 93%,91.2%,87.2% and 63.2%, were sensitive to Amoxicillin /Clavulanic acid, Gentamycin, Cloxacillin, Sulphamethoxazole /Trimethoprim while87.7%,86.0%,84.2% and 82.5%of isolates were resistant to Nalidixic acid, Streptomycin, Oxytetracycline and Penicillin-G.
Reliable detection of rotor faults under the influence of low frequency load torque oscillations for applications with speed reduction couplings

Low frequency torque oscillations in the load can induce frequency components in the vicinity of that of rotor faults resulting in false alarms when applying motor current signature analysis (MCSA). False rotor fault indications due to load oscillations are most common in applications that employ speed reduction couplings for high torque, low speed operation. Recently, ideas for separating rotor faults and load oscillations have been proposed in the literature; however, the case where two components overlap at the same frequency has not been investigated. Several cases where rotor fault- and load oscillation-induced components are identical have been observed in the field by the authors with commercial MCSA equipment. It is shown in this paper that overlap between the two components can produce a false positive or false negative indication because they can add or cancel depending on the relative phase between the components. Alternative options for reliable rotor fault testing are evaluated and verified in this paper for cases where the two components overlap and produce false indications.
Clinical Features of Chinese Sporadic Leber Hereditary Optic Neuropathy Caused by Rare Primary mtDNA Mutations.

OBJECTIVE The primary aim of this study was to describe clinical features of Chinese sporadic Leber hereditary optic neuropathy (LHON) caused by rare primary mitochondrial DNA (mtDNA) mutations. METHODS We characterized a Chinese patient cohort with rare primary mtDNA mutations at Beijing Tongren Hospital between 2015 and 2018. The clinical features of these patients were retrospectively recorded and analyzed. RESULTS Sixteen patients with LHON who had the selected rare primary mutations, including m.4171C>A (3 patients), m.10197G>A (1 patient), m.14459G>A (4 patients), and m.14502T>C (8 patients), were evaluated. The mean age at disease onset was 15 ± 6 years, and the male to female ratio was 15:1. Of 32 eyes of all patients, 75% (24/32) had a worst Snellen best-corrected visual acuity ≤0.1 (worse than 20/200), while 67% (2/3) who were carrying the m.4171C>A mutation experienced significant visual improvement. In addition, 40% (2/5) of patients with LHON carrying only m.14502T>C mutation had only mild visual impairment. Isolated manifestations of LHON was present in 94% (15/16) of all patients; 1 patient with the m.14459G>A mutation had LHON plus dystonia. Brain MRI T2 short tau inversion recovery sequences demonstrated optic atrophy in 62.5% (10/16); increased T2 signal in the optic nerve was found in 38% (6/16) of patients. The patient with LHON plus dystonia demonstrated optic atrophy and increased T2 signal in basal ganglia. CONCLUSION Patients with LHON and rare primary mutations have diverse clinical phenotypes. Those with the m.4171C>A mutation are more likely to have a good visual prognosis, while the m.14502T>C mutation may play a synergistic role in disease onset. Increased signal in the optic nerve on MRI is not rare, and this feature should not exclude LHON as the potential cause for optic neuropathy.
Synthesis of 1-Nitronaphthalene under Homogeneous Conditions

Various reagents can be used for the nitration of naphthalene ranging from the classical nitrating mixture to unusual reagent systems. In this study, a simple and effective method of nitration of naphthalene using a classical nitrating mixture in 1,4-dioxane is presented. The reaction occurs under homogeneous conditions and GC-MS analysis of the product showed 2 peaks corresponding to 1-nitronaphthalene (96%) and 2nitronaphthalene (4%). Melting point, UV and IR spectra of the product (isolated in 96-97% yields) correspond to 1-nitronaphthalene.
Change detection of vehicle-sized targets in forest concealment using VHF- and UHF-band SAR

We describe an extensive data collection and analysis of change detection using VHF- and UHF-band SAR data. Two airborne systems (CARABAS-II: 22-82 MHz, LORA: 225-470 MHz) acquired data for multiple headings and incidence angles. Twenty one targets of five types were deployed in forest concealment. CARABAS-II gives the best performance for the target types investigated. Analysis of the data shows that performance degrades for increasing incidence angle, mainly due to reduced target radar cross-section. It is also shown that different change detectors give different performances. The best detector for one incidence angle is not necessarily best for another incidence angle.
The Efficacy of Body-Oriented Yoga in Mental Disorders–A Systematic Review and Meta-Analysis

BACKGROUND The efficacy of body-oriented yoga in the treatment of mental disorders has been investigated in numerous studies. This article is a systematic review and meta-analysis of the relevant publications. METHODS All studies in which the efficacy of hatha-yoga, i.e., body-oriented yoga with asanas and pranayama, was studied in adult patients suffering from a mental disorder (as diagnosed by ICD or DSM criteria) were included in the analysis. The primary endpoint was disorder-specific symptom severity. The publications were identified by a systematic search in the PubMed, Web of Science, PsycINFO and ProQuest databases, supplemented by a search with the Google Scholar search engine and a manual search in the reference lists of meta-analyses and primary studies, as well as in specialized journals. RESULTS 25 studies with a total of 1339 patients were included in the analysis. A large and significant effect of yoga was seen with respect to the primary endpoint (symptom severity) (Hedges' g = 0.91; 95% confidence interval [0.55; 1.28]; number needed to treat [NNT]: 2.03), with substantial heterogeneity (I2 = 69.8%) compared to untreated control groups. Small but significant effects of yoga were also seen in comparison with attention control (g = 0.39; [0.04; 0.73]; NNT: 4.55) and physical exercise (g = 0.30; [0.01; 0.59]; NNT: 5.75); no difference in efficacy was found between yoga and standard psychotherapy (g = 0.08; [-0.24; 0,40]; NNT: 21.89). In view of the relatively high risk of bias, these findings should be interpreted with caution. CONCLUSION Body-oriented yoga with asanas and pranayama as central components is a promising complementary treatment for mental disorders and should be investigated in further high-quality studies.
Short report: Inclusion of other in the self scale: An adaptation and exploration in a diverse community sample

We adapted the widely used measure of relationship closeness, the Inclusion of Other in Self Scale (IOS), to assess communal coping (IOS-CC). Communal coping is a construct that reflects a shared appraisal of a stressor (“our problem” instead of “my problem”) and collaborative action to manage the stressor. We administered the IOS and the IOS-CC to a racially and economically diverse sample of persons with type 2 diabetes and their partners (n = 207 couples) and examined how a subset (n = 85 couples) interpreted the IOS-CC as well as the IOS. The IOS-CC was largely interpreted as intended. The IOS reflected interpersonal connection, as expected, but also a number of other relationship constructs. The IOS-CC and IOS were positively related, but empirically distinguished by stronger connections of the IOS-CC to communal coping and stronger connections of the IOS to relationship quality. Future researchers should consider using the IOS-CC to measure communal coping when a simple, visual, and less time-intensive measure is needed and consider the different ways the IOS is conceptualized by diverse populations.
