Toward precise constraints on growth of massive black holes

, 2008
Growth of massive black holes (MBHs) in galactic centers comes mainly from gas accretion during their QSO/AGN phases. In this paper we apply an extended Soltan argument, connecting the local MBH mass function with the time-integral of the QSO luminosity ...

The Origin of Dust in the Early Universe: Probing the Star Formation History of Galaxies by their Dust Content [PDF]

, 2010
Two distinct scenarios for the origin of the ~ 4 \times 10^8 M\odot of dust observed in the high-redshift (z = 6.4) quasar J1148+5251 have been proposed.

The First Comprehensive Photometric Study of the Algol-type System CL Aurigae

, 2010
We present the first extensive photometric results of CL Aur from our BVRI CCD photometry made on 22 nights from 2003 November through 2005 February. Fifteen new timings of minimum light were obtained.

Phenomenological modelling of eclipsing system light curves

, 2015
The observed light curves of most eclipsing binaries and stars with transiting planets can be well described and interpreted by current advanced physical models which also allow for the determination of many physical parameters of eclipsing systems ...

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Outcome and cost‐effectiveness of transdiagnostic cognitive behavioral therapy compared with management as usual for youth with common mental health problems: Long‐term results from the Mind‐My‐Mind randomized trial

Journal of Child Psychology and Psychiatry, EarlyView.
Background Credible long‐term outcomes from randomized trials evaluating the effectiveness and cost‐effectiveness of preventive programs for mental health problems are needed. We compared long‐term effects of the Mind My Mind (MMM) transdiagnostic cognitive behavioral therapy (CBT) program to management as usual (MAU). Methods The study was a pragmatic,

State of the art review : language testing and assessment (part two). [PDF]

, 2002
In Part 1 of this two-part review article (Alderson & Banerjee, 2001), we first addressed issues of washback, ethics, politics and standards. After a discussion of trends in testing on a national level and in testing for specific purposes, we surveyed ...
