An 85-year-old woman was found comatose. Her right pupil was 2 mm and reactive while the left pupil was 6.5 mm and nonreactive (figure, A). Oculocephalic and corneal reflexes were absent, the cough reflex was preserved, and there was spontaneous bilateral decerebrate posturing. Traditional teaching indicates that midbrain lesions cause fixed, midposition pupils while pontine lesions cause pinpo...

This paper reports a CFD modeling study to investigate the hydrogen-air mixture combustion in a micro scale chamber. Nine species with nineteen reversible reactions were considered in the premixed combustion model. The effect of operational and geometrical conditions including; combustor size, wall conductivity, reactant flow rates and hydrogen feed splitting on combustion stabilit...

In recent years, various intrusion detection and prevention systems have been proposed to detect DDoS attacks and mitigate the caused damage. However, many existing IDS systems still keep per-flow state to detect anomaly, and thus do not scale with link speeds in multigigabit networks. In this paper, we present a two-level approach for scalable and accurate DDoS attack detection by exploiting t...

While technology scaling increases density and near threshold voltage operation slashes energy consumption, serious reliability concerns such as radiation-induced soft errors and timing violations due to Process Variation (PV) become exacerbated. For instance, the probability of single upsets, and more realistically, multiple upsets, is projected to increase several fold at sealevel for sub-10n...

The advancement of transmission electron microscopy has made it possible to analyze the metallographic structure of steel products on a nanoscopic scale, which leads to the detail understanding of microstructures such as fine precipitates and grain boundaries. The application of the characteristic technology to commercial steel products requires consistency in the structural analysis of steel f...

The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas nuclease system is a powerful tool for genome editing, and its simple programmability has enabled high-throughput genetic and epigenetic studies. These high-throughput approaches offer investigators a toolkit for functional interrogation of not only protein-coding genes but also noncoding DNA. Historically, noncoding DNA...

in this study, a general theoretical model to foresee and calculate the current-voltagecharacteristics in a plateau zone and the associated efficiency of the neutron detector (sensitivity) is presented. this study is to complete the previous studies in this field. the model also considers electric field distortion resulting from the charge collection effect. the characteristics curve is obtaine...

background: the aim of this work was to study the output factors for linac using different ionization chambers and build up caps. materials and methods: output factors were measured for open square fields (3 × 3 cm to 40 × 40 cm) defined by collimator jaws for 6 and 15 mv photon beams from a varian clinac 2100c accelerator were measured. the measurements in air were performed using compact cyli...

purpose : cataract surgery is the most common ocular surgery worldwide and in modern era of phacoemulsification with posterior chamber intraocular lens (pc iol) implantation, refractive aspects of surgery is as important as the surgery itself. after the iol implantation, the anterior chamber depth (acd) is increased and the iridiocorneal angle is widened. these changes should be considered for ...

despite promising results observed using silicone rubber chamber, no previous comprehensive work was performed on behavior of the conduit. present study aimed at further functional, histomorphometrical and immunohistochemical assessment of nerve regeneration in the same animal along a 10-mm rat sciatic nerve gap. fifty- four male wistar rats were divided into three experimental groups (n = 18),...
