هندسه ناجابجایی، هندسه فضاهای کوانتمی را مطالعه می کند. به عبارت ساده تر، این کار به معنی مطالعه خواص هندسی جبرهای ناجابجایی است. اساس کار بر توجه به این نکته است که رسته های مختلفی از فضاها را می توان به وسیله جبرهای جابه جایی نگاشت ها بر آنها کاملا توصیف کرد. در این صورت به یک جبر جابجایی می توان به عنوان جبر نگاشت ها بر یک فضای ناجابجایی نگریست. حال سوال این است: خاصیت هندسی یک جبر ناجابجای...

Background: Studies of the association between post operative AF and Plasma level of NT- Pro BNP have reported conflicting findings. The aim of the present study was evaluation of the association between post coronary bypass graft- Atrial Fibrillation (AF) and Plasma level of NT- ProBNP as an independent risk factor of AF development in patients undergoing coronary artery bypass graft. Methods...

This experiment was conducted to study the effect of Aflatoxins (AF) on broiler performance, organ weight, plasma characteristics, protein digestibility, and metabolizable energy of the diets. Dietary treatments were: 1) control diet based on corn and soybean meal; 2, 3 and 4) control diet plus 1 mg kg-1 AF, 1 mg kg-1 AF and 0.25% mycosorb, and 0.25% Mycosorb, respectively. The results in the A...

The optimal catheter ablation approach for longstanding persistent atrial fibrillation (AF) remains elusive despite significant advances made in our understanding of this arrhythmia. A recent systematic review highlighted the significant variation in procedural success rate both within and between techniques, necessitating repeat ablation procedures and anti-arrhythmic drugs to achieve improved...

Introduction: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmias that cardiologists and internists encounter. The goal of this article is to clarify an overview of the evidence linking inflammation to AF existence, which may highlight the effect of some pharmacological agents that have genuine potential to reduce the clinical burden of AF by modulating inflammatory pathways. Mat...

Journal: Surgery and Trauma 2016

Introduction: Atrial fibrillation (AF) is the most common complication of cardiac surgery which may cause remarkable morbidity and complications. Identifying predicting factors of this arrhythmia can help prophylactic therapy. The present study is designed to investigate the hypothesis that HsCRP level and P-wave characteristics are associated with the incidence of post-operative AF. Methods: ...
