When the sunlight illuminates the front surface of solar cell, part of the incident energy reflects from the surface, and part of incident energy transmits to the inside of solar cell and converts into electrical energy. Typically, the reflectivity of bare silicon surface is quite higher; more than 30% of incident sunlight can be reflected. In order to reduce the reflection loss on the surface ...

The extraction and summarization of opinions in text is a useful task that lends itself naturally to connectionist models of sequential data analysis, such as RNNs and LSTMs. Recent work by Irsoy et al. [11] has shown that RNNs (particularly bidirectional deep RNNs) can be quite successfully applied to the task of identifying opinionated phrases in text. Further, Wang et al. [19] have worked on...

Maru et al. (2012) provide an insightful synthesis about the poverty and rigidity traps. They note how these states can be quite resilient and undesirable for indigenous cultures. We support their approach and add three additional considerations. (1) Maru et al. (2012) tend to interchange adaptive capacity and resilience as concepts. Adaptive capacity and resilience have two different purposes....

THERE is, in the Warwick County Record Office, a pocket cash book measuring 543'4 by 3+" in which entries were made from September 1828 to December 1831.1 The name "Henry Peart" is written on the flyleaf, and all that was known about him when the cash book was first seen was that it belonged to a medical man. Every entry in the book is financial: "cash received" on the left-hand pages, "cash pa...

Recycled tires continue to be used in the construction of rubberized playground surfaces in California. To function as an effective means of reducing the incidence of serious head injury when children fall in the playground, these surfaces should meet standards for impact attenuation, as cited in the California Code of Regulations (sections 6570065750). This study was conducted to determine whe...

A piecewise quintic G1 spline surface interpolating the vertices of a triangular surface mesh of arbitrary topological type is presented. The surface has an explicit triangular Bézier representation, is affine invariant and has local support. The twist compatibility problem which arises when joining an even number of polynomial patches G1 continuously around a common vertex is solved by constru...

BACKGROUND AND AIMS In the last decade, genomic studies using DNA markers have strongly influenced the current phylogeny of angiosperms. Genome size and ploidy level have contributed to this discussion, being considered important characters in biosystematics, ecology and population biology. Despite the recent increase in studies related to genome size evolution and polyploidy incidence, only a ...

Let M and N be doubly connected Riemann surfaces with $${\mathscr {C}}^{1,\alpha }$$ boundaries nonvanishing conformal metrics $$\sigma $$ $$\wp respectively, assume that is a smooth metric bounded Gauss curvature $${\mathcal {K}}$$ finite area.

Since the work of Katz, Douglas, and their collaborators almost half a century ago (Katz, 1969), a central concept in the physiology of neurosecretion is that a rise in cytosolic [Ca], resulting from Ca influx, triggers exocytosis. More recently it has become clear that the rise in [Ca] occurs in a microdomain within the vicinity (i.e., at a distance of 200–300 nm in chromaffin cells) of plasma...
