Siamo interessati a risolvere i seguenti problemi: Problema 1 (Covering Problem,CP) Trovare la copertura di costo totale minimo, cioè il sottoinsieme J ′ di J tale che: 1. Ognuna delle caselle è ricoperta da almeno un pezzo contenuto in J ; 2. La somma dei “costi” dei pezzi di J ′ è minima tra tutti i sottoinsiemi che soddisfano (1). Problema 2 (Partitioning Problem,PP) Trovare la partizione di...

In this paper we present research on applying a domain specific high-level abstractions (HLA) development strategy with the aim to “future-proof“ a key class of high performance computing (HPC) applications that simulate hydrodynamics computations at AWE plc. We build on an existing high-level abstraction framework, OPS, that is being developed for the solution of multi-block structured mesh-ba...

Le persone organizzano sempre di più ogni aspetto della propria vita attraverso l’utilizzo di sistemi software, dal lavoro al trasporto alla salute. Possiamo essere sicuri che i programmi dai quali ci accingiamo a dipendere sono affidabili ? Tali programmi possono tollerare maltrattamenti degli utenti? Questa tesi affronta il problema di verificare i sistemi software rispetto ad errori introdot...

Previous studies of early diabetic retinopathy have shown that oscillatory potential (OP) amplitudes are reduced in many diabetic patients. OP amplitude is believed to be a more sensitive indicator of the development of future retinopathy than b-vvave amplitude of the scotopic electroretinogram (ERG). Because OPs measured to a bright white flash reflect both rod and cone system activity, it is ...

The microcirculation plays a crucial role in the interaction between blood and tissues both in physiological and pathophysiological states. Despite its critical role in numerous diseases including diabetes, hypertension, sepsis or multiple organ failure, methods for direct visualization and quantitative assessment of human microcirculation at the bedside are limited. Orthogonal polarization spe...

Objective: Organophosphorus compounds (OPs) are common causes of poisonings. Atropine and oximes are pharmacological antidotes of OPs. However, because of their adverse effects and insufficient performance, several other compounds have been evaluated as adjuvant therapy. HESA-A is a herbal-marine drug that contains material from Carum carvi (Persian cumin), Penaeus latisculatus...

Despite the fact that Esenbeckia leiocarpa, a Brazilian plant, possesses potential anti-inflammatory properties, its effect in neutrophils, key players in inflammation, has never been investigated. In this study, a crude hydroalcoholic extract (CHE) was used to evaluate the potential toxic or agonistic effect of E. leiocarpa in human neutrophils. At a noncytotoxic concentration of 500 μg/mL, CH...

BACKGROUND Health expenditure for tuberculosis (TB) care often pushes households into catastrophe and poverty. New Cooperative Medical Scheme (NCMS) aims to protect households from catastrophic health expenditure (CHE) and impoverishment in rural China. This article assesses the effect of NCMS on relieving CHE and impoverishment from TB care in rural China. METHODS Three hundred fourty-seven ...

OBJECTIVE To evaluate the trend of catastrophic health expenses (CHE) for inpatient care in relation to the commencement of the New Cooperative Medical Scheme (NCMS) in rural China from 2003 to 2013, and the roles of NCMS in protecting affected households from CHE. METHODS We assessed the 10-year trend of the incidence and severity of CHE in rural households with hospitalised members using da...

We construct bivariate orthogonal polynomials (OPs) on algebraic curves of the form y m = ϕ ( x ) $y^{m} \phi (x)$ in R 2 ${\mathbb {R}}^2$ where 1 , $m 1, 2$ and is a polynomial arbitrary degree d, terms univariate semiclassical OPs. compute connection coefficients that relate OPs to basis itself whose span contains as subspace. The matrix shown be banded Jacobi matrices for 0 … N $0, \ldots N...
