The paper reports on a systematic survey of the literature around the manifold theme of workarounds in computer-supported cooperative work and in so doing presents a range of definitions that focus on different aspects of this phenomenon. We also report a case study in a large hospital where we discussed with some key users the opportunity of a tool that could promote awareness of existing work...
Classical concepts of mechanics applied to continuous materials cannot be used directly for associations of soil clods occurring in ploughed and harrowed topsoils. Therefore, we are proposing a new simpli®ed method for analysing the clod : clod mechanics, for a wide range of clay content. We pressed together axially two adherent remoulded soil balls and recorded a dimensionless strain ̄attening...
Purpose This study aims to assess the predictive factors and treatment outcomes of Steinstrasse formation following shock wave lithotripsy (SWL) for ureter stone. Materials and Methods The medical records of 1,418 ureter stone patients who underwent one-session SWL from November 2005 to May 2013 at our medical institute were retrospectively reviewed. Finally, 551 patients met inclusion criter...
Most patients with first-time kidney stones undergo limited evaluations, and few receive preventive therapy. A prediction tool for the risk of a second kidney stone episode is needed to optimize treatment strategies. We identified adult first-time symptomatic stone formers residing in Olmsted County, Minnesota, from 1984 to 2003 and manually reviewed their linked comprehensive medical records t...
PURPOSE The aim of our study was to evaluate the association of several factors with spontaneous stone expulsion, including ureteral stone characteristics (size, location, hydronephrosis, perinephric stranding), types of medications prescribed (α-blocker, low-dose steroid), and other possible demographic and health-history factors (gender, age, serum creatinine, underlying diabetes mellitus [DM...
performance optimization of chisel tine was proposed by using a chisel plow with adjustable rake angle. effective treatments consisted of soil moisture at 0.5, 0.7 and 0.9 of plastic limit (pl), three rake angle of 30, 40 and 50 degree and speeds of to 3, 5 and 7 km h-1. the measured parameters included draft, soil disturbance area, soil upheaving area, clod mean weight diameter (mwd), specific...
prevalence of urolithiasis in childhood is increasing. the wide geographic variation in the incidence of lithiasis in childhood is related to climatic, dietary, and socioeconomic factors. many children with stone disease have a metabolic abnormality. in southeast asia, urinary calculi are endemic and are related to dietary factors. the main aim of this study was to determine the prevalence of r...
Deep convolutional semantic segmentation (DCSS) learning doesn’t converge to an optimal local minimum with random parameters initializations; a pre-trained model on the same domain becomes necessary to achieve convergence.In this work, we propose a joint cooperative end-to-end learning method for DCSS. It addresses many drawbacks with existing deep semantic segmentation learning; the proposed a...
A stepping-stone connection has always been assumed as an intrusion since the first research on stepping-stone connections twenty years ago. However, not all stepping-stone connections are malicious. This paper proposes an enhanced stepping-stone detection (SSD) technique which is capable to identify legitimate connections from stepping-stone connections. Stepping-stone connections are identifi...
