BACKGROUND A study was undertaken to evaluate the reliability of a digital tracheal sound analyser (ELENS-DSA) in predicting nocturnal changes in airways resistance in asthmatic patients. This device allows continuous measurement of the proportion of the time occupied by wheezing (Wh%). METHODS Nocturnal polygraphic studies with simultaneous continuous monitoring of tracheal sounds and airway...

Wh-phrases in English can appear both raised and in-situ. However, only in-situ wh-phrases can take semantic scope beyond the immediately enclosing clause. I present a denotational semantics of interrogatives that naturally accounts for these two properties. It neither invokes movement or economy, nor posits lexical ambiguity between raised and in-situ occurrences of the same wh-phrase. My anal...

Multiple interrogatives like (1a) readily admit paired answers like (1b). That answers to (2a) and (3a) also pair values for two wh-expressions instead of one has therefore been taken as evidence that two whs have matrix scope. In the case of (2a) the wh-in-situ thought to have wide scope is inside a wh-complement; in the case of (3a) it is inside an adjunct. Wh-in-situ, it would appear, can ta...

Let V ∈ R be a nonnegative matrix. The nonnegative matrix factorization (NNMF) problem consists of finding nonnegative matrix factors W ∈ R and H ∈ R such that V ≈ WH. Lee and Seung proposed two algorithms which find nonnegative W and H such that ‖V −WH‖F is minimized. After examining the case in which r = 1 about which a complete characterization of the solution is possible, we consider the ca...

Replication forks are vulnerable to wayward nuclease activities. We report here our discovery of a new member in guarding genome stability at replication forks. We previously isolated a Drosophila mutation, wuho (wh, no progeny), characterized by a severe fertility defect and affecting expression of a protein (WH) in a family of conserved proteins with multiple WD40 repeats. Knockdown of WH by ...

Barley is the only crop in the Poaceae family with adhering husks at maturity. The color of husk at barely development stage could influence the agronomic traits and malting qualities of grains. A barley mutant with a white husk was discovered from the malting barley cultivar Supi 3 and designated wh (white husk). Morphological changes and the genetics of white husk barley were investigated. Hu...

A lab-scale ensiling study was carried out to investigate the fermentation quality of water hyacinth (WH) supplemented with molasses, rice bran, as an absorbent, and an inoculant in the form of fermented vegetable juice and their combinations. After wilting the water hyacinths for 7 h to a dry matter (DM) content of 240 to 250 g/kg, the following treatments were applied: i) Control (C), WH only...

As is well-known, wh-phrases in Mandarin Chinese can be used as interrogative pronouns, existential indefinites, or universal quantifiers, and regardless of which interpretation they receive, they remain in-situ at S-Structure. In addition, it is not the case that these different usages are freely available in all contexts, as illustrated by the following examples. (1)ta mai sheme shu she buy w...

BACKGROUND This study examined ethnic differences in ageing perceptions of migrant Turkish and native Dutch elders residing in Rotterdam, and explored whether such differences could be attributed to culture or resources (personal, physical, economic and/or social). METHODS This study was based on combined data from two research projects focusing on the health and well-being of community-dwell...
