Supervised datasets play a central role as standards against which to benchmark long-term progress in computer vision. Over the past decade, the PASCAL [2] and Berkeley segmentation datasets (BSDS) [3] have filled these roles for the object detection and image segmentation tasks, respectively. The type of annotation available for each dataset determines the particular visual subtasks to which i...

background: doppler indices of umbilical artery are used as indicator of fetal well being. objective: to compare doppler parameters of umbilical artery including pulsatility index (pi) and resistance index (ri) in patients with preeclampsia with those of normal pregnancies and to evaluate the diagnostic characteristics of these parameters in preeclampsia. materials and methods: in a case contro...

OBJECTIVE Albuminuria can be caused by endothelial dysfunction as a result of ischemic nephropathy rather than classic diabetic nephropathy. We studied whether renal vascular resistance (resistive index [RI]) of the main renal arteries could be associated with albuminuria and further assessed the relationship between RI and aorta stiffness measured by brachial-ankle pulse-wave velocity (baPWV)....

Previously, we demonstrated that ischemia induces mitochondrial damage and dysfunction that persist throughout reperfusion and impact negatively on postischemic functional recovery and cellular viability. We hypothesized that viable respiration-competent mitochondria, isolated from tissue unaffected by ischemia and then injected into the ischemic zone just before reperfusion, would enhance post...

In 4 experiments on retroactive interference (RI), we varied paired-associate learning lists that produced either appreciable or negligible forgetting. When the category of the stimulus word predicted its response word category, and the response was relatively unique within its category, learning was extremely rapid, and negative transfer and RI were negligible. The more the competing primed it...

This is a closed subscheme ofX ; locally, where the bundles are trivial, this is defined by vanishing of the minors of size rij +1 in the product of matrices giving the map φj ◦ · · · ◦ φi+1 from Ei to Ej , for all i < j. Not all rank conditions give reasonable loci. Those that do—and the only ones we will consider—are characterized by the conditions rij ≤ ri,j−1 and rij ≤ ri+1,j for all i < j,...

BACKGROUND In patients with multiple myeloma, renal impairment (RI) at the time of diagnosis is associated with poor survival. To the authors' knowledge, the current retrospective analysis presented is the first to assess the impact of various degrees of renal dysfunction on safety and efficacy outcomes in a large cohort of patients with relapsed and/or refractory multiple myeloma who received ...
