We previously presented YM500, which is an integrated database for miRNA quantification, isomiR identification, arm switching discovery and novel miRNA prediction from 468 human smRNA-seq datasets. Here in this updated YM500v2 database (http://ngs.ym.edu.tw/ym500/), we focus on the cancer miRNome to make the database more disease-orientated. New miRNA-related algorithms developed after YM500 we...

JEL classification: R21 R31 Construction quality is a major problem in China's housing market. We investigate whether the housing market could provide incentives to encourage developers to promote construction quality beyond the compulsory, minimum standards by testing the financial viability of efforts made in this field by developers. This study takes place in the city of Beijing, where the “...

To examine several mechanisms for the generation of lowand high-frequency tropical waves, numerical experiments are conducted using an idealized nine-level R21 spectral model with the original scheme of moist convective adjustment (MCA). The model prescribes globally uniform, time-independent distributions of sea surface temperatures and insolation, thereby excluding stationary waves and extrat...

Immigration and Housing Booms: Evidence from Spain We estimate empirically the effect of immigration on house prices and residential construction activity in Spain over the period 1998-2008. This decade is characterized by both a spectacular housing market boom and a stunning immigration wave. We exploit the variation in immigration across Spanish provinces and construct an instrument based on ...

We present the first (as of February, 1999) UBV and uvby photometric measurements for the short period variable star V2109 Cyg discovered by the Hipparcos satellite and classified as a field RRc variable. We have obtained new times of maxima and the period change has been studied. We determined the fundamental physical parameters using the geometric distance of the star and the most recent synt...

We estimate the eff ect of the Dutch-German border on house prices. In the last 40 years the development of house prices in the Netherlands and Germany has been substantially diff erent. While the Netherlands have been hit by two real estate cycles, prices in Germany have been extraordinary stable. We develop a model for studying house prices and the impact of the border. Then we study the deve...

A Longitudinal Analysis of Moving Desires, Expectations and Actual Moving Behaviour Many theories of residential mobility contend that individuals express a sequence of moving desires, intentions and expectations prior to moving. Much research has investigated how individuals form these pre-move thoughts, with a largely separate literature examining actual mobility. Only a few studies have atte...

We present detections of the CO(J = 1–0) emission line in a sample of four massive star-forming galaxies at z ∼ 1.5 − 2.2 obtained with the Karl G. Jansky Very Large Array (VLA). Combining these observations with previous CO(2–1) and CO(3–2) detections of these galaxies, we study the excitation properties of the molecular gas in our sample sources. We find an average line brightness temperature...

Radiation characteristics of fused quartz containing bubbles (10 % porosity) are determined using inverse method based on theoretical and experimental bi-directional transmittances and reflectances. The Discrete Ordinates Method is used to solve the RTE. The internal and external interfaces are assumed to be optically smooth. The importance of the choice of the interpolation law has been shown,...
