background a doctor’s competence and professionalism is often judged on the basis of attire. our lady of lourdes (olol) is a leading irish hospital in the implementation of bare below the elbows (bbte) policy, however surgical attire is not standardised and there is great variability in attire worn on wards. we aimed to evaluate patients attitude towards surgeons attire in olol.   methods a pro...

including baseline length and tilt. Successful implementation Ground tie points have been used to improve the accuracy of a DEM derived from interferometric SAR (I~SAR) data. The number of tie points required for ensuring certain accuracy of the I~SAR-derived DEM was investigated in this study in two ways. One is the least-squares estimate of the corrections to a DEM using tie points, and the o...

As a spread phenomenon, tacit knowledge integration has been attracting more attention because of the embeddedness in social activities and interactions. Our works, as a complement to previous research, investigate tacit knowledge integration based on social networks from transactive memory systems (TMS) perspective. We focus on ties dimension (expressive tie, instrumental tie, and tie strength...

Activation of endothelial cells, important in processes such as angiogenesis, is regulated by cell surface receptors, including those in the tyrosine kinase (RTK) family. Receptor activity, in turn, can be modulated by phosphorylation, turnover, or proteolytic release of a soluble extracellular domain. Previously, we demonstrated that release of soluble tie-1 receptor from endothelial cells by ...

Consensus does not exist on the level of arterial ligation in rectal cancer surgery. From oncologic considerations, many surgeons apply high tie arterial ligation (level of inferior mesenteric artery). Other strategies include ligation at the level of the superior rectal artery, just caudally to the origin of the left colic artery (low tie), and ligation at a level without any intraoperative de...

The tie gene encodes a receptor tyrosine kinase that is expressed in the endothelium of blood vessels, particularly during embryonic development and angiogenesis in adults. We have cloned and characterized the mouse tie gene and isolated the human and mouse tie promoters. The promoter activities of human and mouse tie were analyzed using luciferase reporter gene constructs in transfected cell l...

Here we present an antenna-integrated QCL which can be actively and optically modulated using light in the near infrared, creating an optical nanocircuit – coupling two different frequency antennas with a nonlinear active switching element. For our design, we chose two cross-polarized bow-tie antennas with an aligned central spot. We have used detailed FDTD simulations to choose the length of e...

This article examines the role of migrant social networks in international migration and extends prior research by testing the strength of tie theory, decomposing networks by sources and resources, and disentangling network effects from complementary explanations. Nearly all previous empirical research has ignored friendship ties and has largely neglected extended-family ties. Using longitudina...

Social network research seldom considers the possible effect of individual psychological differences on network structures. We propose several hypotheses about how individual differences might predispose actors to structure their immediate social environment in terms of seeking network closure or a preparedness to sustain structural holes. To investigate these hypotheses, we introduce a new met...
