least squares method (lsm) is an accurate and rapid method for solving some analytical andnumerical problems. this method can be used to estimate the average reservoir pressure in well testanalysis. in fact, it may be employed to estimate parameters such as permeability (k) and porevolume (vp). regarding this point, buildup, drawdown, late transient test data, modified muskatmethod, interferenc...

We propose a numerical method for maintaining a dynamic rolling motion of animated gaseous phenomena, such as smoke, that avoids dissipation due to numerical error. We compensate for the errors induced by a semi-Lagrangian scheme using an error estimate for each time interval. We develop a new advection term and perform vortex advection based on a vorticity confinement force. Example simulation...

We consider the problem of spatial channel covariance matrix (CCM) estimation for intelligent reflecting surface (IRS)-assisted millimeter wave (mmWave) communication systems. Spatial CCM is essential two-timescale beamforming in IRS-assisted systems; however, estimating challenging due to passive nature elements and large size resulting from massive IRS. In this paper, we propose a method by e...

BACKGROUND National community-based health worker (CBHW) programs often face challenges in ensuring that these remote workers are adequately trained, equipped and supervised. As governments increasingly deploy CBHWs to improve access to primary health care, there is an urgent need to assess how well health systems are supporting CBHWs to provide high quality care. METHODS This paper presents ...

BACKGROUND In October 2007, manufacturers voluntarily withdrew over-the-counter (OTC) infant cough and cold medications (CCMs) from the US market. A year later, manufacturers announced OTC CCM labeling would be revised to warn against OTC CCM use by children aged <4 years. We determined whether emergency department (ED) visits for CCM adverse drug events (ADEs) declined after these intervention...

CCM is a conventional authenticated-encryption scheme obtained from a 128-bit block cipher. The mechanism has been adopted as the mandatory encryption algorithm in an IEEE 802.11 draft stan­ dard [15], and its use has been proposed more broadly [16, 17]. In this note we point out a number of limitations of CCM. A related note provides an alternative to CCM [5].

BACKGROUND Wagner's Chronic Care Model (CCM), as well as the expanded version (ECCM) developed by Barr and colleagues, have been widely adopted as frameworks for prevention and management of chronic disease. Given the high prevalence of chronic illness in older persons, these frameworks can play a valuable role in reorienting the health care system to better serve the needs of seniors. We aimed...

Virtually every mammalian cell, including cardiomyocytes, possesses an intrinsic circadian clock. The role of this transcriptionally based molecular mechanism in cardiovascular biology is poorly understood. We hypothesized that the circadian clock within the cardiomyocyte influences diurnal variations in myocardial biology. We, therefore, generated a cardiomyocyte-specific circadian clock mutan...

INTRODUCTION Respiratory failure is a common problem in emergency medicine (EM) and critical care medicine (CCM). However, little is known about the resuscitation of critically ill patients prior to emergency endotracheal intubation (EETI). Our aim was to describe the resuscitation practices of EM and CCM physicians prior to EETI. METHODS A cross-sectional survey was developed and tested for ...
