مقدار و جهت تغییر شکل¬ها در یک نقطه در داخل یا روی تاج سد در طی مراحل مختلف ساخت و بهره¬برداری از مخزن ممکن است تغییر کند. به کمک رفتار نگاری داده¬های ابزار دقیق سد می¬توان جابجایی¬¬های سد در سه جهت قائم، عمود و موازی با محور سد را اندازه¬گیری کرد. با توجه به هزینه¬های هنگفت که برای احداث سدها صرف می¬شود، نیاز به در نظر گرفتن حداکثر تمهیدات لازم است تا از ایجاد هر گونه مشکلی که در پایداری و ایم...

Compressed sensing (CS) can recover sparse signals from undersampled measurements. In this work, we have developed an advanced CS framework for photoacoustic computed tomography (PACT). During the reconstruction, a small part of the nonzero signals’ locations in the transformed sparse domain is used as partially known support (PKS). PACT reconstructions have been performed with under-sampled in...

The Streif in Kitzbühel, Austria, is regarded as the most challenging ski downhill race. It starts with the ‘Mausefalle’ (the mousetrap), a stunning, almost vertical jump—the most dangerous in the whole championship circuit—that propels skiers within seconds to a rocket speed and a landing compression of over 1000 kg (Fig. 1). Every champion will tell you that you may have already lost the race...

3-tert-Butyl-7-(5-methylisoxazol-3-yl)-2-(1-methyl-1H-1,2,4triazol-5-ylmethoxy)-pyrazolo[1,5-d][1,2,4]triazine (MRK-016) is a pyrazolotriazine with an affinity of between 0.8 and 1.5 nM for the benzodiazepine binding site of native rat brain and recombinant human 1-, 2-, 3-, and 5-containing GABAA receptors. It has inverse agonist efficacy selective for the 5 subtype, and this 5 inverse agonism...

The UNL, either as language or as a system, is not well known due to several reasons. At this moment, UNL is not only the name of a language for computers aiming at supporting multililingual services in Internet. It is also a system, with a defined architecture and a wide panorama of applications and possibilities to support business, institutional and educational applications, all of them goin...

Systemically or centrally administered agmatine (decarboxylated arginine) prevents, moderates, or reverses opioid-induced tolerance and self-administration, inflammatory and neuropathic pain, and sequelae associated with ischemia and spinal cord injury in rodents. These behavioral models invoke the N-methyl-D-aspartate (NMDA) receptor/nitric-oxide synthase cascade. Agmatine (AG) antagonizes the...
