Clairvoyant performance bounds for adaptive beamforming in pulse-echo imaging.

In adaptive beamforming, the array signal processing adjusts its sensor delays and weights based on the incoming data. In conventional beamforming, these parameters are instead given from a predefined model. Adaptive beamformers can improve measurement precision by dynamically rejecting spatial interference.

Decreased Duration of Hospital Stays in Uncomplicated Diverticulitis With Initiation of Enteral Feeds Within 24 Hours.

Diverticulitis is a complication of a mostly benign condition called diverticulosis. Diverticulitis is a common illness that medical staff see in emergency departments and hospital inpatient services. The thought process behind this study was looking at the treatment of other diseases like pancreatitis or other critical illnesses and the data supporting timing of feeds.

Circumpolar Population Structure, Diversity and Recent Evolutionary History of the Bearded Seal in Relation to Past and Present Icescapes.

The Arctic environment plays a critical role in the global climate system and marine biodiversity. The region's ice-covered expanses provide essential breeding and feeding grounds for a diverse assemblage of marine species, who have adapted to thrive in these harsh conditions and consequently are under threat from global warming. The bearded seal (Erignathus barbatus), including two subspecies (E.

The Teitge test.

Introduction: High tibial osteotomy (HTO) is used to treat medial knee osteoarthritis (OA). A simple clinical test to select the patients most likely to benefit from the procedure was suggested by R. A.

The effect of temperature constraints on the treatment of tumors using focused ultrasound-induced acoustic streaming.

The transport of drugs into tumor cells near the center of the tumor is known to be severely hindered due to the high interstitial pressure and poor vascularization. The aim of this work is to investigate the possibility to induce acoustic streaming in a tumor. Two tumor cases (breast and abdomen) are simulated to find the acoustic streaming and temperature rise, while varying the focused ultrasound transducer radius, frequency, and power for a constant duty cycle (1%).
