In this paper, we study the limitations imposed by the laws of electromagnetism on achievable MIMO channel capacity in its general form. Our approach is a three-fold one. First, we use the channel correlation argument to demonstrate that the minimum antenna spacing under any scattering conditions is at least half a wavelength. Secondly, using a planewave spectrum expansion of a generic electrom...

The microtubule associated protein tau is essential for the development and maintenance of the nervous system. Tau dysfunction is associated with a class of diseases called tauopathies, in which tau is found in an aggregated form. This paper focuses on a small aggregating fragment of tau, (273)GKVQIINKKLDL(284), encompassing the (PHF6*) region that plays a central role in tau aggregation. Using...

One of the most significant topics for therapeutic endoscopy in recent years is the develop‐ ment of new therapeutic strategies for gastric neoplasms, called endoscopic submucosal dis‐ section (ESD)[1]-[7]. This technique was developed to allow resection of difficult lesions with characteristics such as large size, irregular shape, coexisting ulcer findings or difficult location that could not ...

Abstract. This study examined the associations between telepressure and work recovery experiences (i.e., psychological detachment, relaxation, control, mastery) tested whether these differ employees working onsite ( n = 158) or remotely 284). Our results revealed that was negatively related to mastery. Moreover, relations were stronger among than those remotely. These helped buffer negative lin...

This paper derives an approach to combine estimates and covariances for decentralized attitude estimation using a quaternion parameterization. The approach is based on the covariance intersection method, which is modified to maintain quaternion normalization in the combination process. A simple simulation result is provided where local extended Kalman filters are used on two star trackers, each...
