Background
Timely diagnosis of meniscus injuries is key for preventing knee joint dysfunction and improving patient outcomes because it decreases morbidity and facilitates treatment planning.
Purpose
To train and evaluate a deep learning model for automated detection of meniscus tears on knee magnetic resonance imaging (MRI).
Study type
Bicentric retrospective study.
Subjects
In total, 584...
The skeleton is one of the most important organs in the human body in assisting our motion and activities; however, bone density attenuates gradually as we age. Among common bone diseases are osteoporosis and Paget's, two of the most frequently found diseases in the elderly. Nowadays, a combination of multiple drugs is the optimal therapy to decelerate osteoporosis and Paget's pathologic process,...
The magnitude of the treatment gap (TG) for convulsive status epilepticus (CSE) in resource‐poor countries is unknown. Hospital‐based cohort studies from developing countries revealed that the management of CSE was usually suboptimal due to lack of advanced diagnostic and treatment facilities, significant delay in patient's presentation at hospital, and shortages of essential antiepileptic drugs (AEDs)...
Polyanilines comprising aniline rings with and without a benzo-15-crown 5-ether (benzo15C5) subunit were synthesized by polycondensation initiated by ammonium persulfate. The treatment of the polymers with NaH caused deprotonation of the NH groups to yield n-doped polyanions. UV–vis spectra of the polyanions exhibited broad absorption above 700 nm corresponding to bipolaron bands. Because of n-dedoping...
In this paper, we propose a sub-optimal technique to solve problem of power allocation in cognitive radio (CR) OFDM-based system. This technique called full-filling based on windowing the CR user's signal and maximizing the power allocation at good sub-carrier positions of CR user. Thank to the interference reduction of windowing technique, the complexity of power allocation optimization problem with...
Ultra wideband (UWB) system using multi antennas and time reversal (TR) possesses capability of multiuser system. Each user with long channel response signature is exploited for multiple access problems. If UWB channels are independent, the multi antenna UWB system shows both capacity and diversity gain. However, due to correlation between antennas, the performance of system degrades. In this paper,...
This paper investigates the impact of windowing on the power allocation in cognitive radio (CR) system. The investigation shows that introducing windowing significantly improves the power allocation and transmission rate of CR as it effectively reduces interference introduced by CR system. Although the windowing technique has been widely introduced to OFDM-based systems, such as WLAN [1], its effect...
Mobile wireless communication systems aim at using battery energy efficiently. One of the main source of depleting precious battery of wireless handheld devices is failure frame transmissions due to collision. This paper provides a detailed analysis of the power consumption of newly introduced MAC protocol called Intelligent Local Avoided Collision (iLAC). Analytical solution confirms the correctness...
