OBJECTIVE Schizophrenia is associated with aberrant event-related potentials (ERPs) such as reductions in P300, processing negativity and mismatch negativity amplitudes. These deficits may be related to the propensity of schizophrenia patients to experience auditory verbal hallucinations (AVH). However, AVH are part of extensive and variable symptomatology in schizophrenia. For this reason non-...

BACKGROUND The Widal test is the most common, specific and quick diagnostic method available in the world for diagnosis of typhoid fever; however, false negativity is one of the obstructive features of the test. The aim of this study was to evaluate the associated factors with Widal test negativity in an endemic area. METHODS Widal test negativity was retrospectively analyzed among culture-pr...

We study an ensemble of two-level systems interacting with a thermal bath. This is a well-known model for glasses. The origin of memory effects in this model is a quasistationary but nonequilibrium state of a single two-level system, which is realized due to a finite-rate cooling and slow thermally activated relaxation. We show that single-particle memory effects, such as negativity of the spec...

The main aim of this paper is to provide a new analysis of licensers of negative polarity items (NPIs). The problems with Fauconnier-Ladusaw's downward entailment analysis have been argued since Linebarger (1980). I will show that there exists a class of weak NPI licensers characterized by non-monotonicity and exclusivity. Weak negation, which is monotone decreasing, has been known to license w...

In this experiment, 97 patients with obstructive sleep apnea hypopnea syndrome were divided into three groups (mild, moderate, severe) according to minimum oxygen saturation, and 35 healthy subjects were examined as controls. Cognitive function was determined using the mismatch negativity paradigm and the Montreal Cognitive Assessment. The results revealed that as the disease worsened, the mism...

In this note we establish the large time limit non-negativity of the heat kernel for a class of elliptic differential operators on closed, Riemannian manifolds, and apply this result to a problem from conformal differential geometry.

Let m ∈ i. We wish to extend the results of [25] to completely pseudo-local graphs. We show that V is sub-measurable. We wish to extend the results of [25] to countably convex, multiply ultra-complete triangles. The groundbreaking work of A. Gupta on monodromies was a major advance.

This article examines the role of the shared family context in understanding differential parental treatment of children. Child-specific and family-context predictors of differential parental positivity and negativity were examined using multilevel modeling in a population of 8,476 children nested in 3,762 families. Child age was the strongest child-specific predictor of positivity and differen...
