Photonic crystals (PhCs) are engineered nanostructures that enable an extraordinary control over the flow of light. These structures can be fabricated out of common semiconductors, are compatible with existing industrial fabrication technologies, and are expected to play a major role in future devices integrating photonic circuits – e.g. for telecommunications or in future quantum technologies....

Abstract Singularity annihilation, generation, and evolving (SAGE) lead to the topological phase transition (TPT) in electronic, photonic acoustic systems. Traditionally singularity study of Hermitian systems is only focused on real frequency domain. In this work, we systematically investigate complicated SAGE complex domain (CFD) for one-dimensional (1D) non-Hermitian a more general picture re...

Abstract Background Electronic Health Records (EHRs) can contribute to the earlier detection and better treatment of chronic diseases by improving accuracy accessibility patient data. The Saudi Ministry (MOH) implemented an EHR system in all primary health care clinics (PHCs) as part measures improve their performance managing disease. This study examined perspective physicians on current scope...

The importance of developing multi-disciplinary approaches to solving problems relating to anthropogenic pollution is now clearly appreciated by the scientific community, and this is especially evident in boreal ecosystems exposed to escalating threats of petroleum hydrocarbon (PHC) contamination through expanded natural resource extraction activities. This review aims to synthesize information...

BACKGROUND A correlation between excess mortality from myocardial infarctions (MI) and schizophrenia has already been established. What remains unclear is whether the initial communication between the treating doctor and the corresponding patient contributes to this excess mortality. AIM The aim of this study is to investigate whether a patient with schizophrenia receives the same offers for ...

One of the fundamental challenges to implementing successful prevention of mother-to-child transmission (PMTCT) programs in Nigeria is the uptake of PMTCT services at health facilities. Several issues usually discourage many pregnant women from receiving antenatal care services at designated health facilities within their communities. The CRS Nigeria PMTCT Project funded by the Global Fund in i...

INTRODUCTION South Africa has made remarkable progress in rolling out antiretroviral therapy (ART), with the largest number of people (more than 1.4 million) enrolled on antiretroviral in the world. Decentralisation of services to primary health centres (PHCs) has strengthened retention of patients on ART and reduced the burden of managing uncomplicated cases at referral hospitals. METHODS Th...

SETTING 40 primary health clinics (PHCs) in four provinces in South Africa, June 2012 -February 2013. OBJECTIVE To determine whether health care worker (HCW) practice in investigating people with TB symptoms was altered when the initial test for TB was changed from smear microscopy to Xpert MTB/RIF. DESIGN Cross-sectional substudy at clinics participating in a pragmatic cluster randomised t...

In the design of photonic integrated circuits (PICs), optical connections PIC surface, along with electronic components chips, are significant issues. One optoelectronics that utilizes these surface electro-reflective modulators, consisting an section and section. this paper, a novel scheme two-dimensional crystals (PhCs) is presented for reflective sections device. This two-dimensional; thus, ...
