In this paper we prove a new chain rule formula for the distributional derivative of the composite function v(x) = B(x, u(x)), where u :]a, b[→ Rd has bounded variation, B(x, ·) is continuously differentiable and B(·, u) has bounded variation. We propose an application of this formula in order to deal in an intrinsic way with the discontinuous flux appearing in conservation laws in one space va...

Outcomes in RCT's of antipsychotic medications are often examined using last observation carried forward (LOCF) and mixed effect models (MMRM), these ignore meaning of non-completion and thus rely on questionable assumptions. We tested an approach that combines into a single statistic, the drug effect in those who complete trial and proportion of patients in each treatment group who complete tr...

BACKGROUND Evaluation of bond strength and microleakage caused by polymerization shrinkage provides a screening mechanism and an indication of the potential for the clinical success of composite restorations. AIM The aim of this study was to determine the effect on shear bond strength and microleakage of standard and expired composites. MATERIALS AND METHODS Selected specimens were etched u...

The data presented in this article are related to a research article entitled 'Highly efficient solar-driven photocatalytic degradation on environmental pollutants over a novel C fibers@MoSe2 nanoplates core-shell composite' (Wang et al., 2018) [1]. In this article, we report original data on the synthesis processes optimization of the proposed composite together with its formation mechanism. T...

Real world applications make heavy use of composite keys to reference entities. Indices over multiple columns are therefore mandatory to achieve response time goals of applications. We describe and evaluate the Composite Group-Key Index for fast tuple retrieval via composite keys from the compressed partition of in-memory column-stores with a main/delta architecture. Composite Group-Keys work d...

An experimental evaluation of the structural health monitoring capability of piezoelectric wafer active sensors on composite structures at cryogenic temperatures is presented. The piezoelectric wafer active sensor–based electromechanical impedance and the pitch–catch methods were first qualified for cryogenic temperatures using piezoelectric wafer active sensor–instrumented composite specimens ...

the effect of adding sodium stearoyl-2-lactylate (ssl) and propylene glycol (pg) (0 - 0.5 g/100g) to emulsifier gel formulation on the crumb and crust characteristics of barbari bread fortified with soy flour in order to optimize these characteristics were evaluated. the obtained results showed that addition of ssl caused an increase in the crumb and crust l* and cell density. the a*, b*, avera...
