Single cell measurement of telomerase expression and splicing using microfluidic emulsion cultures. [PDF]

, 2014
Telomerase is a reverse transcriptase that maintains telomeres on the ends of chromosomes, allowing rapidly dividing cells to proliferate while avoiding senescence and apoptosis.

Bimodality in simulated precipitation frequency distributions and its relationship with convective parameterizations

npj Climate and Atmospheric Science
Bimodality in precipitation frequency distributions is often evident in atmospheric models, but rarely in observations. This study i) proposes a metric to objectively quantify the bimodality in precipitation distributions, ii) evaluates model simulations

Galaxy evolution by color-log(n) type since redshift unity in the Hubble Ultra Deep Field

, 2008
We explore the use of the color-log(n) plane (where n is the global Sersic index) as a tool for subdividing the high redshift galaxy population in a physically-motivated manner.

Multimodal Differential Emission Measure in the Solar Corona [PDF]

, 2015
The Atmospheric Imaging Assembly (AIA) telescope on board the Solar Dynamics Observatory (SDO) provides coronal EUV imaging over a broader temperature sensitivity range than the previous generations of instruments (EUVI, EIT, and TRACE).

A randomized controlled trial to study the effect of supplemental premilking stimulation on milking performance, teat tissue condition, udder health, and well-being in dairy cows

Journal of Dairy Science
: The objectives of this study were to evaluate the effect of supplemental premilking stimulation, provided after manual stimulation, by means of high-frequency pulsation without reduction of the vacuum in the pulsation chamber on milking performance ...

A Distribution Dynamics Approach to Regional GDP Convergence in Unified Germany [PDF]

This paper uses nonparametric techniques to study GDP convergence across German labor market regions and counties during the period 1992-2004. The main result is that regional convergence in unified Germany has been substantial.

Many-body physics in the radio frequency spectrum of lattice bosons

, 2009
We calculate the radio-frequency spectrum of a trapped cloud of cold bosonic atoms in an optical lattice. Using random phase and local density approximations we produce both trap averaged and spatially resolved spectra, identifying simple features in the

A Coupled Oscillator Model for the Origin of Bimodality and Multimodality

, 2020
Perhaps because of the elegance of the central limit theorem, it is often assumed that distributions in nature will approach singly-peaked, unimodal shapes reminiscent of the Gaussian normal distribution.

A regulatory role for repeated decoy transcription factor binding sites in target gene expression

Molecular Systems Biology, 2012
Tandem repeats of DNA that contain transcription factor (TF) binding sites could serve as decoys, competitively binding to TFs and affecting target gene expression.

Bimodal fission of Hs*

Journal of Physics: Conference Series, 2014
Mass and energy distributions of fission fragments obtained in the reactions 22Ne + 249Cf, 26Mg + 248Cm, and 22Ne + 238U have been measured. A special attention will be paid on the properties of mass-energy distribution of fission fragments obtained in the reaction 26Mg + 248Cm at an excitation energy of 35 MeV.
