Optimum ψ (for population values known) – Penalty reduces average loss by ∼ 60− 70% – 2-step method (PEP) almost as effective as penalised estimation (MVP) Pick ψ so that ΔL ≈ −2χ 5%,1 – change in logL not significant – under-penalisation, but achieve substantial proportion of reduction in loss possible – results for PEP more variable than for MVP Little difference between types of penalty Resu...
OBJECTIVE Patients with familial dysautonomia have an increased risk of sudden death. In some patients with familial dysautonomia, sympathetic cardiac dysfunction is indicated by prolongation of corrected QT (QTc) interval, especially during stress tests. As many patients do not tolerate physical stress, additional indices are needed to predict autonomic risk. In familial dysautonomia there is ...
Autoantibodies to the γ-aminobutyric acid receptor, subtype B (GABAB), are a known cause of limbic encephalitis. The spectrum of clinical manifestations attributable to this antibody is not well defined at the present time. Here we present a case of GABAB encephalitis presenting with encephalopathy, status epilepticus, dysautonomia, and acute heart failure. To our knowledge, heart failure and d...
Our article on “arrhythmic” mitral valve prolapse (MVP) triggered a debate among clinical cardiologists about the implications in terms of diagnosis, risk stratification, and therapy. Thus, the letters by Sheppard et al and Providencia and Lambiase are welcome and give us the opportunity to be back on this hot topic. Sheppard et al, by studying a series of sudden cardiac death (SCD) victims wit...
سابقه و هدف: بیماری دهشت pd (panic disorder) و پرولاپس دریچه میترال mvp (mitral valve prolaps) دو اختلال نسبتا شایع هستند که در سال های اخیر، ارتباط بین آنها مورد توجه پژوهشگران قرار گرفته است. این سوال که آیا mvp در بیماران مبتلا به دهشت شایع تر از کل جمعیت است، هنوز به درستی پاسخ داده نشده است. به منظور پاسخ به این سوال، مطالعه مذکور طراحی و به انجام رسیده است. مواد و روش ها: این تحقیق، یک مط...
Equine dysautonomia, or grass sickness, is a frequently fatal disease of unknown etiology, manifested as poor gastrointestinal motility and colic as a result of degenerative changes in the autonomic nervous system. Examination of ileal biopsies collected at laparotomy is currently the best antemortem diagnostic method to distinguish equine dysautonomia from colic cases, which can present with s...
Despite the continued development of advanced algorithms for phylogeny reconstruction, the assessment of topological accuracy remains a challenging problem. New tools are needed to assist researchers in the prediction and evaluation of phylogenetic performance, particularly when short alignments are considered. We present a probabilistic analysis of quartet accuracy by the four-point method (FP...
Various factors, such as identity, view, and illumination, are coupled in face images. Disentangling the identity and view representations is a major challenge in face recognition. Existing face recognition systems either use handcrafted features or learn features discriminatively to improve recognition accuracy. This is different from the behavior of primate brain. Recent studies [5, 19] disco...
