In present trend of integration will continue in the projected future. When comparing the integration density of integrated circuits, a clear distinction must be made between the memory chips and logic chips. Memory circuits are highly regular. Increase of chip complexity is consistently higher for memory circuits. The salient features such as low power, reliable performance, circuit techniques...

We present the characterisation and validation of multiplexed 4-terminal (4T) impedance measurements as a method for sensing the spatial location of cell aggregates within large three-dimensional (3D) gelatin scaffolds. The measurements were performed using an array of four rectangular chambers, each having eight platinum needle electrodes for parallel analysis. The electrode positions for curr...

Ginkgolic acids (GA) have been reported to exhibit anticancer properties, however, 15 the mechanisms remain unclear. This study aims to investigate the mechanisms of GA C13:0 16 that was isolated from Ginkgo biloba exocarp (GBE) for anti-proliferation, pro-apoptosis and 17 anti-migration effects in human MCF-7 and mouse 4T-1 breast cancer cells. The cytotoxic 18 effect, apoptosis induction and ...

Picrotoxin, an antagonist for γ-aminobutyric acid receptor subtype A (GABAA), was used to investigate the role of GABAA receptors in nociceptive and nonnociceptive reflex bladder activities and pudendal inhibition of these activities in cats under α-chloralose anesthesia. Acetic acid (AA; 0.25%) was used to irritate the bladder and induce nociceptive bladder overactivity, while saline was used ...

Reed and Wood and independently Norine, Seymour, Thomas, and Wollan proved that for each positive integer t there is a constant c(t) such that every graph on n vertices with no Kt-minor has at most c(t)n cliques. Wood asked in 2007 if we can take c(t) = c for some absolute constant c. This question was recently answered affirmatively by Lee and Oum. In this paper, we determine the exponential c...

In this multicenter study, 2D spatial mapping of J-coupled resonances at 3T and 4T was performed using short-TE (15 ms) proton echo-planar spectroscopic imaging (PEPSI). Water-suppressed (WS) data were acquired in 8.5 min with 1-cm(3) spatial resolution from a supraventricular axial slice. Optimized outer volume suppression (OVS) enabled mapping in close proximity to peripheral scalp regions. C...

زمینه و هدف: سندرم بوتولیسم توسط نوروتوکسین باکتری کلستریدیوم بوتولینوم ایجاد می شود. این نوروتوکسین دارای 7 سروتیپ از a-g می باشد. بهترین روش برای پیشگیری از سندرم حاصل از نوروتوکسین بوتولینوم (bont)، استفاده از واکسن های نوترکیب ساخته شده از ناحیه اتصالی آن (به علت داشتن اپی توپ های کافی برای تحریک سیستم ایمنی) می باشد. در این مطالعه ناحیه اتصالی نوروتوکسین بوتولینوم تیپ a (bont/a) بررسی گردی...

Complexity of geometric symmetry for differential operators with mixed homogeniety is examined here. Sharp Sobolev estimates are calculated for the Grushin operator in low dimensions using hyperbolic symmetry and conformal geometry. Considerable interest exists in understanding differential operators with mixed homogeneity. A simple example is the Grushin operator on R ∆G = ∂ ∂t2 + 4t ∂ ∂x2 . T...

We investigated a family of horses exhibiting irregular vertical stripes in their hair coat texture along the neck, back, hindquarters, and upper legs. This phenotype is termed "brindle" by horse breeders. We propose the term "brindle 1 (BR1)" for this specific form of brindle. In some BR1 horses, the stripes were also differentially pigmented. Pedigree analyses were suggestive of a monogenic X...

Bovine ephemeral fever is an acute and arthropod-borne viral disease of cattle and water buffalo which occurs seasonally in most of the world tropical and subtropical regions. The epizootic feature of the disease has been reported in Iran with serious economic consequences. The surface glycoprotein G of bovine ephemeral fever virus (BEFV) is composed of 4 antigenic sites (G1-G4) and plays the m...
