Abstract

In this study, we report the length dependence of thermal conductivity (k) of zinc-blende Zinc-Selenide (ZnSe) and Zinc Telluride (ZnTe) for length scales between 10 nm and 10000 nm using first-principles computations based on density-functional theory. k value of ZnSe is computed to decrease significantly from 11.3 W/mK to 1.75 W/mK as the length scale is diminished from 10 nm to 10 nm. k value of ZnTe is also observed to decrease from 10 W/mK to 1.2 W/mK for the same decrease in length. We also measure the k of bulk ZnSe and ZnTe using Frequency Domain Thermoreflectance (FDTR) technique and observed a good agreement between FDTR measurements and first principles calculations for the bulk ZnSe and ZnTe. Understanding of thermal conductivity reduction at nanometer length scales provides an avenue to incorporate nanostructured ZnSe and ZnTe for thermoelectric applications., Comment: 19 pages, 13 figures

27. A unique approach to address avoided crossings in the charge stabilization curve for LUMO identification.

Abstract

In quantum chemistry, Lowest Unoccupied Molecular Orbital (LUMO) is important for studying various chemical processes, including photochemical reactions, electron attached states, and electron excites states. Recently, an effective method has been introduced that involves the use of the Parametric Equation of Motion (PEM) in conjunction with the nuclear charge stabilization method for precise identification of true LUMO. However, the inclusion of extra diffuse functions in the basis set, which is necessary for describing electron-attached and electron-excited states, can cause issues due to the presence of the same symmetry states, leading to avoided crossing. Identifying the true LUMO among these avoided crossings is challenging due to the mixing of states and the exchange of their orbital character. This article introduces a modification of the PEM to identify the true LUMO by preventing the stabilization of specific states involved in avoided crossings. The present method is highly effective and requires minimal computational cost. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Tuberculosis (TB) is a chronic infectious multisystemic disease caused by Mycobacterium tuberculosis and is one of the leading causes of mortality worldwide. Both common mental disorders (CMD) and TB are global public health problems that have a considerable impact on human health. Moreover, TB and CMDs share common risk factors including poverty, drug addiction, and homelessness and the coexistence of CMD and TB leads to difficult management of TB. Materials and Methods: This was a hospital-based longitudinal study, carried out between June 2021 and December 2022. In this study, 147 pulmonary TB patients were included as per inclusion and exclusion criteria, and psychiatric illness was evaluated by the Brief Psychiatric Rating Scale. Results: The mean age of study participants was 37.59 ± 15.37 years, there were 99 (67.3%) were male and 48 (32.7%) were female. Psychiatric illness was found in 77 (52.38%) pulmonary TB patients. Among psychiatric illness, anxiety was found in 33 (22.4%) participants and 21 (14.3%) participants had depression. Mixed anxiety and depression were found in 20 (13.6%) patients and 03 (2%) participants had severe psychosis. The association of psychiatric illness with age group and gender was not significant (P = 0.734, 0.203, respectively). There were 105 (71.40%) patients who had <12 standard education and 42 (28.60%) had >12 standard education and their association with psychiatric illness was statistically significant (P = 0.044). Adverse drug reactions were found among 80 (54.42%) patients and the association between adverse drug reactions and psychiatric illness was significant (P = 0.031). Conclusion: Psychiatric illness is one of the important domains to be evaluated in timely manner in TB patients and early intervention is needed for better management of the TB because the severity, social factors, and chronicity of the disease make them susceptible to develop psychiatric illness.
