Background and purpose: Febrile seizure (FS) is the most common type of seizure in children which is triggered byvariety of causes. The aim of this study was to evaluate and compare the serum level of magnesium (Mg) in three groups: children with FS (A), febrile children without seizure (B) and normal children (C). Also, this study investigated the relationship between severity of fever and ser...
Background A recent MRI pilot study [1] indicated that hemodynamics in the Fontan circulation are mainly dependent on respiration according to flow amplitudes and suggested using a respiratory-triggered 4D PC MRI instead of a ECG-triggered 4D PC MRI. The detailed validation of this conclusion with double-triggered PC on acquisition level requires an extensive development of the pulse sequence. ...
This paper compares current sensor fusion models and proposes a new time-triggered model for sensor fusion. The time-triggered sensor fusion model decomposes a real time system into three levels, a node level, containing the sensors and the actuators, a cluster level that gathers measurements and performs sensor fusion, and an application level where an application program makes control decisio...
The test effort required for full test coverage is much higher in event-triggered than in time-triggered real-time systems. Thus, it is hard to attain sufficient confidence in the correctness of event-triggered real-time applications by testing. We present a general upper bound on the test effort of constrained event-triggered real-time systems, assuming multiple resources (a refinement of prev...
We propose a method for improving the tolerance of synchronous circuits to delay variations on the clock distribution. Instead of retiming and clock skew scheduling applied to edge-triggered flip-flops, as used by most other methods, we use level-sensitive latches placed based on a schedule of the operations. The resulting circuit can have a non-zero tolerance even at the optimal clock period...
Recent studies at the single-molecule level show how signaling from the giant protein titin can be triggered by direct mechanical activation of its kinase domain.
Background and Aim: Breast cancer is the most common type of cancer among women. A subset of isoflavones such as phytoestrogens (plant estrogens) have mammalian estrogen-like properties. Alfalfa has high isoflavone content. The aim of this study was to examine the effect of alfalfa’s isoflavones on breast cancer and lipid profile in these patients. Materials and Methods: Thirty BALB-C mi...
In order to directly evaluate the role of the cAMP-dependent protein kinase (PKA) catalytic (C) subunit in T-cell receptor- (TCR) triggered cytotoxic T-lymphocytes (CTL) effector functions, cells were studied after pretreatment with antisense oligomers complementary to mRNA for the C alpha or C beta subunits. C alpha subunit is shown to be predominantly expressed in CTL. In some experiments the...
مرحله گذارقطع یک راهکار بسیارسودمند جهت تجزیه وتحلیل سری های زمانی تصادفی است. مادراین پایان نامه با معرفی این روش به تحقیق در مورد سری های زمانی فواصل ضربان قلب و سری زمانی شاخص بورس سهام چندشرکت وزبری سطح دررشد لایه های نازک می پردازیم. دراین روش می توان بااستفاده از تابع توزیع چگالی احتمال ?_?^+ نسبت به ? وهمچنین تابع توزیع چگالی احتمال بیشترین نقاط برخورد نسبت به مقدار شیب، تمایز قلب سالم و...
As part of an effort to develop a systematic methodology for earthquake forecasts, we use a simple model of seismicity based on interacting events which may trigger a cascade of earthquakes, well-known as the Epidemic-Type Aftershock Sequence model). The ETAS model is constructed on a (bare) Omori’s law, the Gutenberg-Richter law and the idea that large events trigger more numerous aftershocks....
