Strain engineering of the silicon-vacancy center in diamond

We control the electronic structure of the silicon-vacancy (SiV) color-center in diamond by changing its static strain environment with a nano-electro-mechanical system. This allows deterministic and local tuning of SiV optical and spin transition frequencies over a wide range, an essential step towards multi-qubit networks. In the process, we infer the strain Hamiltonian of the SiV revealing large strain susceptibilities of order 1 PHz/strain for the electronic orbital states. We identify regimes where the spin-orbit interaction results in a large strain suseptibility of order 100 THz/strain for spin transitions, and propose an experiment where the SiV spin is strongly coupled to a nanomechanical resonator

Kritik zehirlenme olgularında mortalite belirteçleri: Tek merkez deneyimi

Objective: Poisoning is among the common health care problems which may be fatal and 3-5% of the acutely poisoned patients need intensive care admission. The aim of this study was to examine the acutely poisoned patients admitted to intensive care unit (ICU) in terms of individual, etiological and demographical characteristics and also to determine the factors affecting mortality. Material and Methods: This study was retrospectively conducted on the patients admitted to medical ICU of a university hospital due to acute poisoning over a six year period. The patients' age, gender, comorbid disease status, sociocultural characteristics, cause of the poisoning, transfer time to hospital and to the ICU, signs and symptoms, laboratory data, Glasgow coma score, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, Sequential Organ Failure Assessment score, length of stay in ICU, the treatments employed and their results were analyzed. Results: The total number of the patients included in the study was 190. The median age of the patients was 28.5 (16-72) years and 97 (51%) patients were females. The mean length of stay in ICU was 4.2±3.6 days. The overall mortality rate was 8.4%. Independent risk factors for mortality were presence of concomitant physical disorders, time to ICU admission, and higher APACHE II scores. Conclusion: Individual characteristics, cause of poisoning and type of toxic agent should be clearly determined since they are predictors for mortality. Early intervention is life saving. ICU scoring systems in predicting mortality are very valuable and should be used. © 2013 by Türkiye Klinikleri

The WHO global alliance against chronic respiratory diseases in Turkey (GARD Turkey)

In order to prevent and control non-communicable diseases (NCDs), the 61st World Health Assembly has endorsed an NCD action plan (WHA resolution 61.14). A package for essential NCDs including chronic respiratory diseases (CRDs) has also been developed. The Global Alliance against Chronic Respiratory Diseases (GARD) is a new but rapidly developing voluntary alliance that is assisting World Health Organization (WHO) in the task of addressing NCDs at country level. The GARD approach was initiated in 2006. GARD Turkey is the first comprehensive programme developed by a government with all stakeholders of the country. This paper provides a summary of indicators of the prevalence and severity of chronic respiratory diseases in Turkey and the formation of GARD Turkey
