nasopharyngeal swab samples from patients with an acute flu-like illness were evaluated for the presence of respiratory syncytial virus (rsv) from october 1996 to march 1998. the relative frequency and seasonal distribution of rsv was assessed. in addition, the virus correlated with specific clinical signs and symptoms. during the study, 268 samples were collected from children under the age of...

Exploiting spatial redundancy in images is responsible for a large gain the performance of image and video compression. The main tool to achieve this called intra-frame prediction. In most state-of-the-art coders, intra prediction applied block-wise fashion. Up now angular was dominant, providing low-complexity method covering variety content. With deep learning, however, it possible create met...

The “Journal Citation Reports” for 2021 have been released, and I am pleased to inform you that the impact factor of IEEE Vehicular Technology Magazine ( xmlns:xlink="http://www.w3.org/1999/xlink">VTM ) has increased 13.609 (from 10.384 in 2020). This is an amazing achievement ranks second ...

The H.266/Versatile Video Coding (VVC) standard is the latest video coding standards released by Joint Exploration Group (JVET). These new technologies have brought more than 40% increase in compression rate and huge complexity. In order to reduce complexity of VVC, we propose a fast Unit (CU) partition decision algorithm combining Bayes Improved De-blocking Filter (IDBF). includes two stages. ...

We recently reported that changes in climatic water balance across much of the state of California have led to downhill shifts in plant species’ distributions (1). Wolf and Anderegg (2), Hijmans (3), and Stephenson and Das (4) contend that our analysis was flawed.We address their comments here. Wolf and Anderegg (2) state that our results are narrowly applicable because of the limited number of...

background influenza type a (h1n1) causes an epidemic disease, resulting in thousands of deaths throughout the world. objectives our aim was comparing the efficacy of two different methods in isolating the influenza (h1n1) virus including cell culture and real-time pcr in tabriz and suburbs. patients and methods of throat swab samples, 220 were collected in viral transport medium (vtm) from pat...

Lysophosphatidylcholine (LPC) accumulates in ischemic but not normal myocardium and has electrophyriological actions. We studied the effects of LPC on passive and active membrane properties and on repolarization in the Purkinje fibers of sheep using multiple microelectrodes: one for intracellular current injection and the other for transmembrane voltage (V_) recording. Synthetic 1palmitoyl LPC ...

The latest versatile video coding (VVC) introduces some novel techniques such as quadtree with nested multi-type tree (QTMT), multiple transform selection (MTS) and reference line (MRL). These tools improve compression efficiency compared the previous standard H.265/HEVC, but they suffer from very high computational complexity. One of most time-consuming parts VVC intra is unit (CTU) structure ...

With the growing data consumption of emerging video applications and users’ requirement for higher resolutions, up to 8K, a huge effort has been made in compression technologies. Recently, versatile coding (VVC) standardized by moving picture expert group (MPEG), providing significant improvement performance over its predecessor high efficiency (HEVC). In this paper, we provide comparati...

Parkinson’s disease (PD) is a neurodegenerative disorder that does not develop spontaneously in some animal species. PD can be induced experimentally in some laboratory animals including mouse, rat and horse. Globus pallidus (GP) and substantia nigra pars compacta (SNc) are damaged in patients with PD. The hallmark of PD is a progressive impaired control of movement, an alteration of autonomic ...
