Human beings have evolved to detect and react to threats in their physical environment, and have developed perceptual systems to assess physical, sensorial stimuli for current, material risks. In cyberspace, those stimuli can be absent, subdued, or deliberately manipulated by antagonistic third parties. Security and privacy concerns that would normally be activated in the offline world, therefo...
Privacy policies often place requirements on the purposes for which a governed entity may use personal information. For example, regulations, such as HIPAA, require that hospital employees use medical information for only certain purposes, such as treatment. Thus, using formal or automated methods for enforcing privacy policies requires a semantics of purpose requirements to determine whether a...
About 30% of monochorionic twin pregnancies are complicated by twin-to-twin transfusion syndrome (TTTS), isolated discordant growth, twin anemia-polycythemia sequence, congenital defects or intrauterine demise. About 15% will be eligible for invasive fetal therapy, either fetoscopic laser treatment for TTTS or fetoscopic or ultrasound-guided umbilical cord coagulation for a severe congenital de...
Genetic structure of skipjack tuna Katsuwonus pelamis from the Indian region was investigated using sequence data of mitochondrial DNA (mtDNA) D-loop region. A total of 315 individuals were sampled from six major fishing grounds around the east and west coasts of India including the Andaman (Port Blair) and Lakshadweep (Minicoy) Islands. Nucleotide and gene diversities were high in all the samp...

Authors have argued that various forms of interventions may be more effective in younger children. Is cognitive training also more effective, the earlier the training is applied? We review evidence suggesting that functional neural networks, including those subserving attentional control, may be more unspecialised and undifferentiated earlier in development. We also discuss evidence suggesting ...
Background: The tyrosine kinase inhibitor imatinib mesylate was developed as an inhibitor of the kinase activity of BCR-ABL. However, imatinib also has potent inhibitory activity against the platelet-derived growth factor receptor (PDGFR). Nilotinib is approved for treating patients with chronic myeloid leukemia showing resistance or intolerance to imatinib. Like imatinib, nilotinib selectively...
The law of intelligence is presented in test independent form. Mental abilities, physical brain size, and infant motor capacity follow the same law of growth from birth to adolescence. Mental growth is independent of race, SES or the Flynn effect. The vitality of the mental age scale calls for a reexamination of Wechsler s deviation IQ. This paper builds on Yen s method of standardized differen...
تحقیق حاضر در دو فصل گرم و سرد سال1390 و1391 برای تعیین غلظت دو فلز V و Ni در بافت عضله و کبد ماهی گیش خال سفید((Carangoiedes malabaricusصید شده از محدوده بندر عباس انجام شد. نمونه ها بیومتری و توزین شده و بافت عضله و کبد جدا گردید. سپس غلظت نیکل و وانادیوم به وسیله دستگاه جذب اتمی کوره اندازه گیری شد. بر اساس نتایج به دست آمده در کل سال میانگین غلظت های نیکل و وانادیوم در کبد 027/0±265/0 و 007...
جریانگلآلود مهمترین پدیده در رسوبگذاری در مخازن، بویژه در نزدیکی دیوارهی سد در محل قرارگیری سازههایی مانند آبگیرهای تحتانی، بوده و میتواند باعث کاهش عمر مفید مخازن گردد. در این مطالعه به بررسی آزمایشگاهی نیمرخهای بیبعد شدهی سرعت جریان گلآلود، در یک نمونه فیزکی از مخزنی که یک تغییر شیب در بسترخود دارد، پرداخته و اثر وجود مانع در تغییر الگوی رسوبگذاری جریان گلآلود، در حالتی که جریان با ...
