background : we aimed to compare hemodynamic and endocrine alterations caused by stress response due to proseal laryngeal mask airway and endotracheal tube usage in laparoscopic cholecystectomy. methods : sixty-three asa i-ii patients scheduled for elective laparoscopic cholecystectomy were included in the study. patients were randomly allocated into two groups of endotracheal tube and proseal ...

BACKGROUND Open mouthpiece ventilation is efficacious in patients with neuromuscular disease. We used this ventilation technique in patients with exacerbations of COPD with mild to moderate acidosis. METHODS The study was performed in 2 respiratory monitoring care units. Fifty subjects with exacerbations of COPD, breathing frequency > 25, PaCO2 > 45, and pH between 7.25 and 7.30, as well as K...

We study a possibility to use the octopole moment of gravitationally lensed images as a direct measure of the third-order weak gravitational lensing effect, or the gravitational flexion. It turns out that there is a natural relation between flexion and certain combinations of octopole/higher-multipole moments which we call the Higher Order Lensing Image’s Characteristics (HOLICs). This will all...

This paper exploits the monotonicity of general isotropic reflectances for estimating elevation angles of surface normal given the azimuth angles. With an assumption that the reflectance includes at least one lobe that is a monotonic function of the angle between the surface normal and half-vector (bisector of lighting and viewing directions), we prove that elevation angles can be uniquely dete...

Most of the auxetic materials that have been characterized experimentally or studied analytically are anisotropic and this limits their possible applications, as they need to be carefully oriented during operation. Here, through a combined numerical and experimental approach, we demonstrate that 2D auxetic materials with isotropic response can be easily realized by perforating a sheet with elon...

Background and Objective: Health Information Technology helps individuals prevent COVID-19. Many information technology applications have been developed to prevent Coronavirus infection globally; however, the quality level of these applications is uncertain. This study aims to evaluate the usability of the Mask mobile application, which is designed to fight COVID-19. Materials and Methods: The...

The increased complexity of resolution enhancement technology (RET) at nanometer processes is significantly impacting lithographic yield. The major contributors to declining yields are smaller lithographic process window, increased sensitivity to layout topology in the lithographic process, and complex mask rule constraints that impact the application of RET. These issues must be addressed with...

Detection and segmentation of objects of interest in image sequences is the first major processing step in visual surveillance applications. The outcome is used for further processing, such as object tracking, interpretation, and classification of objects and their trajectories. To speed up the algorithms for moving object detection, many applications use techniques such as frame rate reduction...

Recently we studied the effects of information carrying waves propagating through isotropic cosmologies. By information carrying we mean that the waves have an arbitrary dependence on a function. We found that the waves introduce shear and anisotropic stress into the universe. We then constructed explicit examples of pure gravity wave perturbations for which the presence of this anisotropic str...

This research work focuses on the experimental investigation of indentation damage resistance and post-indented performance different stacking sequence glass/epoxy laminates using mechanical acoustic responses. The with sequence, namely [0]12, [0/90]6S, [+45/-45]6S [0/+45/-45/90]3S were subjected to normal inclined emission monitoring. Quasi-static (QSI) test was conducted center a hemispherica...
