High frequency sound waves in vitreous silica

We report a molecular dynamics simulation study of the sound waves in vitreous silica in the mesoscopic exchanged momentum range. The calculated dynamical structure factors are in quantitative agreement with recent experimental inelastic neutron and x-ray scattering data. The analysis of the longitudinal and transverse current spectra allows to discriminate between opposite interpretations of the existing experimental data in favour of the propagating nature of the high frequency sound waves.Comment: 4 pages, Revtex, 4 ps figures; to be published in Phys.

Plasmon coupled super- and sub- radiance from dye shells

Article investigates cooperative spontaneous emission, theoretically and experimentally, for an ensemble of emitters coupled to a core-shell structure

Scattering Suppression in Epsilon-Near-Zero Plasmonic Fractal Shells

This article studies silica-gold core-shell microspheres with plasmonic fractal shells to show that the forward scattering of the silica microspheres is strongly suppressed

Patient care workshop organized by heart failure association of the European Society of Cardiology

Introduction: The patient care workshop was organized by the heart failure (HF) association of the European Society of Cardiology (ESC) in Vilnius, Lithuania on October 26, 2018. Cardiologists, general practitioners, and nurses from nine countries were invited to the workshop. Background: HF is a complex clinical syndrome that requires a complex treatment regimen and is associated with frequent hospitalizations, poor quality of life, high morbidity and mortality. The practice of evidence-based guidelines of HF will help for continued professional development among cardiologists, practitioners, and nurses who manage HF. Program: The workshop was divided into five sessions. The sessions were focused on the following topics: (1) ESC newer guideline for diagnosis, including the BNP and echocardiography, On-going management with drug optimization and advanced therapies-ICD/CRTD/LVADs, (2) the specialist HF programs and its curriculum, (3) the importance of setting up centers with specialized experts in treating HF patients and the importance of a multidisciplinary approach to managing HF, (4) components of a HF program, (5) HF patient's health education, (6) self-care management, (7) medication adherence, (8) discharge counseling, (9) discharge planning of patient with comorbidities, (10) different approaches of home-based management at “community level” and “home visits,” (11) The role of the cardiologist, General practitioner, and Nurses within the HF team, (12) The specialized HF nurse curriculum, and (13) practical considerations for setting up an HF specialized service- money, personnel, room, specialized curriculum for training the personnel, supporting agencies, and network around the globe. Conclusion: Educational programs for cardiologists, general practitioners, and nurses may benefit HF patients and may lead to increased adherence to the clinical guidelines related to selection and optimization of drugs, proper use of advanced device therapies, setting of HF clinics, and thereby increase the patient's health-care utilization. In India, more specialized centers for treating heart failure need to be created and the nurse led heart failure clinics must be developed in larger scale for the better care of heart failure patients

Sequencing and Computational Approaches to Identification and Characterization of Microbial Organisms

The recent advances in sequencing technologies and computational approaches are propelling scientists ever closer towards complete understanding of human-microbial interactions. The powerful sequencing platforms are rapidly producing huge amounts of nucleotide sequence data which are compiled into huge databases. This sequence data can be retrieved, assembled, and analyzed for identification of microbial pathogens and diagnosis of diseases. In this article, we present a commentary on how the metagenomics incorporated with microarray and new sequencing techniques are helping microbial detection and characterization
