The species abundance distribution (SAD) is one of the most intensively studied distributions in ecology and its hollow-curve shape is one of ecology's most general patterns. We examine the SAD in the context of all possible forms having the same richness (S) and total abundance (N), i.e. the feasible set. We find that feasible sets are dominated by similarly shaped hollow curves, most of which...

OBJECTIVE To assess the psychometrics of the schedule for affective disorders and schizophrenia for school-age children present and lifetime version (K-SADS-PL) in diagnosing DSM-IV psychiatric disorders and subsyndromal symptomatology in preschool children. METHOD Parents were interviewed about their children using the K-SADS-PL, and they completed the early childhood inventory-4 (ECI-4) and...

OBJECTIVE In two related studies, we explored the prevalence of migraine and its associated clinical characteristics in patients with bipolar disorder (BD) as well as psychiatric morbidity in patients treated for migraine. METHOD The first study included 323 subjects with BD type I (BD I) or BD type II (BD II), diagnosed using the Schedule for Affective Disorders and Schizophrenia, Lifetime v...

This article represents the French translation of the Schedule for Affective Disorders and Schizophrenia (SADS), developed by researchers at the New York State Psychiatric Institute and Columbia University (New York) to permit the selection of homogeneous samples of patients presenting with a defined psychiatric illness. The SADS was developed in the mid-1970s in an effort to provide research i...

Objective: The supraglottic airway (SAD) is considered a viable alternative to endotracheal intubation, particularly in cases where SAD not contraindicated. plays crucial role difficult algorithms, offering unobstructed oxygenation and ventilation, as well providing hemodynamic stability with minimal laryngopharyngeal morbidity. LMA-classic, introduced by Archie Brain 1983, was the first second...

Most patients with autoimmune diseases are thought to have a a normal life expectancy, and thus are treated conservatively. However, these diseases have a diverse clinical course. A small subset of patients have "severe autoimmune diseases," or SADS, which are rapidly progressive and are associated with early mortality. If patients with SADS can be identified before they develop irreversible or...

Speech activity detection (SAD), the task of locating speech segments from a given recording, remains challenging under acoustically degraded conditions. In 2015, National Institute of Standards and Technology (NIST) coordinated OpenSAD bench-mark. We summarize “HAPPY” team effort to OpenSAD. SADs come in both unsupervised and supervised flavors, the latter requiring a labeled training set. Our...

A detailed model for the electronic properties of self-assembled InAs/GaAs quantum dots (SADs) is presented, with emphasis on inter-level transitions and many-body effects. The model is based on the self-consistent solution of three-dimensional Poisson and Schrödinger equations within the local (spin-) density approximation. Nonparabolicity of the band structure and a continuum model for the st...
