Quantum teleportation with nonclassical correlated states in noninertial frames

Quantum teleportation is studied in noninertial frame, for fermionic case, when Alice and Bob share a general nonclassical correlated state. In noninertial frames two fidelities of teleportation are given. It is found that the average fidelity of teleportation from a separable and nonclassical correlated state is increasing with the amount of nonclassical correlation of the state. However, for any particular nonclassical correlated state, the fidelity of teleportation decreases by increasing the acceleration.Comment: 10 pages, 3 figures, expanded version to appear in Quantum Inf.

Development and validation of the Multi-dimensional University Research Workplace Inventory (MDURWI)

WOS:000454839600005This study describes the development and validation of an instrument aimed toward measuring organizational features of an academic research workplace. The question pool was developed based on data from a pilot study (N = 43). The survey was deployed to academic researchers in the field of higher education research worldwide (N = 850). An exploratory factor analysis conducted on 36 questions, followed by confirmatory factor analysis, which lead to a final pool of 27 questions in five subscales, one of which divided into three lower-order factors. The final model exhibited very good fit (X2/df = 2.561; CFI = 0.972; PCFI = 0.784; RMSEA = 0.043; P[rmsea ? 0.05] < 0.001; AIC = 891.018; BCC = 987.839) and psychometric properties, in the form of factorial, convergent, and discriminant validity, as well as reliability and sensitivity. Implications of this instrument for research and policymaking are discussed, as well as future research directions.info:eu-repo/semantics/acceptedVersio

Putative psychosis genes in the prefrontal cortex: combined analysis of gene expression microarrays

<p>Abstract</p> <p>Background</p> <p>Recent studies have shown similarities between schizophrenia and bipolar disorder in phenotypes and in genotypes, and those studies have contributed to an ongoing re-evaluation of the traditional dichotomy between schizophrenia and bipolar disorder. Bipolar disorder with psychotic features may be closely related to schizophrenia and therefore, psychosis may be an alternative phenotype compared to the traditional diagnosis categories.</p> <p>Methods</p> <p>We performed a cross-study analysis of 7 gene expression microarrays that include both psychosis and non-psychosis subjects. These studies include over 400 microarray samples (163 individual subjects) on 3 different Affymetrix microarray platforms.</p> <p>Results</p> <p>We found that 110 transcripts are differentially regulated (p < 0.001) in psychosis after adjusting for confounding variables with a multiple regression model. Using a quantitative PCR, we validated a set of genes such as up-regulated metallothioneins (MT1E, MT1F, MT1H, MT1K, MT1X, MT2A and MT3) and down-regulated neuropeptides (SST, TAC1 and NPY) in the dorsolateral prefrontal cortex of psychosis patients.</p> <p>Conclusion</p> <p>This study demonstrates the advantages of cross-study analysis in detecting consensus changes in gene expression across multiple microarray studies. Differential gene expression between individuals with and without psychosis suggests that psychosis may be a useful phenotypic variable to complement the traditional diagnosis categories.</p

Some of these fractures need surgery. Considering the diversity of surgical methods available for these kinds of fractures and also the importance of achieving full function and speedy return to work for patients that are mainly young workers or athletes, this study was undertaken to investigate the outcome of treating these fractures by mini-plates.&quot;n&quot;nMethods : Eighteen patients with open or comminuted fractures of metacarpal bones who were admitted to the emergency department of Sina Hospital between the years 2007 and 2010 underwent fixation surgery using mini-plates. Fourteen patients with 17 metacarpal fractures completed the study.&quot;n&quot;nResults : Thirteen out of 14 patients had complete fracture union. The patient with non-union underwent revision surgery and bone graft. Four individuals developed an extensor lag of 15 degrees without functional impairment. Two patients had joint stiffness that was relieved after a period of physiotherapy and one developed wound dehiscence and discharge that improved with debridement and use of antibiotics without plate removal. Six patients had complaints regarding their hardware prominence and were satisfied after its removal. Overall, there was a 79% satisfaction rate upon the treatment.&quot;n&quot;nConclusion: Despite the afore-mentioned complications, use of mini-plates seems to be a suitable treatment option for patients with comminuted metacarpal fractures. However, more studies with larger sample sizes are suggested to reach a firm conclusion.&quot;n&quot;nKeywords: Fracture, metacarpal, mini-plates, complication

Development and psychometric evaluation of the Treatment Adherence Questionnaire for Patients with Combat Post-traumatic Stress Disorder

This study developed and psychometrically assessed the Treatment Adherence Questionnaire for Patients with Combat Post-Traumatic Stress Disorder. Participants and methods: This methodological study was conducted in Tehran, Iran, during 2016&ndash;2017 in two phases. First, the concept of treatment adherence in combatants with PTSD was analyzed using a hybrid model. This model consisted of three phases: literature review phase, fieldwork phase, and final analysis phase. The consequences and attributes of the concept of treatment adherence in combatants with PTSD were identified, and based on the findings, the Treatment Adherence Questionnaire for PTSD veterans was developed. In the second stage, the face and content validities of the questionnaire were investigated both quantitatively and qualitatively. Exploratory factor analysis and confirmatory factor analysis were used to determine the questionnaire&rsquo;s validity. Internal consistency correlation coefficient of the questionnaire was estimated with Cronbach&rsquo;s alpha coefficient, while the reliability of the questionnaire was established using intra-class test-retest correlation coefficient. Study participants were selected from inpatients and outpatients referred to a hospital, clinic, and health center in Tehran and Kashan, Iran. All patients were diagnosed with combat PTSD by a psychiatrist, based on psychiatric interview and other clinical findings. Results: The Persian version of the Treatment Adherence Questionnaire for Patients with Combat Post-Traumatic Stress Disorder included 17 items. Exploratory factor analysis identified three factors which accounted for a total of 87.57% of the total variance of treatment adherence score. The identified factors were labeled as &ldquo;maintenance of treatment&rdquo;, &ldquo;follow-up and treatment contribution&rdquo;, and &ldquo;purposefulness and responsibility&rdquo;. The Cronbach&rsquo;s alpha correlation coefficient was 0.92 and the intra-class correlation coefficient of the questionnaire&rsquo;s reliability was estimated at 0.92 (P&lt;0.001). Conclusion: The data obtained confirmed the hypothesis of the factor structure model with a latent second-order variable. The final version of the Treatment Adherence Questionnaire for Iranian combatants with PTSD can be applied as a valid and reliable questionnaire for measuring treatment adherence in these patients.
