The generalization ability of discrete time partially recurrent networks is examined. It is well known that the VC dimension of recurrent networks is infinite in most interesting cases and hence the standard VC analysis cannot be applied directly. We find guarantees for specific situations where the transition function forms a contraction or the probability of long inputs is restricted. For the...

BACKGROUND KDIGO (Kidney Disease: Improving Global Outcomes) guidelines recommend that a lateral abdominal radiograph should be performed to assess vascular calcification (VC) in dialysis patients. However, abdominal aortic calcification is a prevalent finding, and it remains unclear whether other anatomical areas of VC can predict mortality more accurately. METHODS A total of 217 maintenance...

Reputation of a venture capitalist (VC) is based on experience, expertise and past performance. We investigate the relation between VC reputation measures and both the probability of future IPOs and their long-run performance. We measure long-run firm performance following three widely used approaches, namely industry-adjusted operating performance, market-to-book ratio, and long-run listing su...

BACKGROUND AND OBJECTIVES Calcification of the mitral and aortic valves is common in dialysis patients (CKD-5D). However, the prognostic significance of valvular calcification (VC) in CKD is not well established. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS 144 adult CKD-5D patients underwent bidimensional echocardiography for qualitative assessment of VC and cardiac computed tomography (CT)...

OBJECTIVES This study was performed to validate the accuracy of color flow vena contracta (VC) measurements of aortic regurgitation (AR) severity by comparing them to simultaneous intraoperative flow probe measurements of regurgitant fraction (RgF) and regurgitant volume (RgV). BACKGROUND Color Doppler imaging of the vena contracta has emerged as a simple and reliable measure of the severity ...

Verrucous carcinoma (VC) of the penis is an uncommon squamous tumor that pursues a biologically indolent course. Unlike conventional squamous cell carcinoma (SCC) of the penis, pathogenic roles for human papillomavirus (HPV) infection and p53 mutation have not been reported in VC. We compared the immunohistochemical expression of Mdm2 and p53 in 7 cases of VC and 7 cases of SCC. The Mdm2 gene p...

The purpose of this literature review is to document academic research concerning factors influencing the performances of venture capital funds, as well as the venture capital fundraising decisions. Industry specialisation, large fund sizes, strong deal flow, syndication of investments, and especially, experience, all appear to be factors leading to superior investment performance, which is par...
