Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

High-Efficient Parameter-Pruning Algorithm of Decision Tree for Large Dataset [PDF]
Jisuanji gongchengDecision tree(DT) have a good effect on data classification but easily develop overfitting. The solution to this problem is to prune the DT. However, the pruning algorithm has shortcomings; for example, prepruning is prone to underfitting, the ...

Large-eddy simulations of surface roughness parameter sensitivity to canopy-structure characteristics [PDF]
Biogeosciences, 2015 Surface roughness parameters, namely the roughness length and displacement height, are an integral input used to model surface fluxes. However, most models assume these parameters to be a fixed property of plant functional type and disregard the ...

The Oblique Parameters In Electroweak Theory with Two Massless Higgs Doublets
, 1993 The oblique parameters $S$ and $T$ are studied in electroweak theory with two massless Higgs doublets. The effect of quadratic dependence on the charged Higgs mass in the parameter $T$ could be cancelled.

Observational Parameters of Blue Large-amplitude Pulsators*
The Astrophysical Journal Supplement SeriesAbstract Blue large-amplitude pulsators (BLAPs) are a recently discovered class of short-period pulsating variable stars. In this work, we present new information on these stars based on photometric and spectroscopic data obtained for known and new objects detected by the Optical Gravitational Lensing Experiment (OGLE) survey.

Cosmological parameter estimation with large scale structure observations [PDF]
Journal of Cosmology and Astroparticle Physics, 2014 We estimate the sensitivity of future galaxy surveys to cosmological parameters, using the redshift dependent angular power spectra of galaxy number counts, $C_\ell(z_1,z_2)$, calculated with all relativistic corrections at first order in perturbation theory.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin
FEBS Letters, EarlyView.The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Attraction of like-charged macroions in the strong-coupling limit
, 2004 Like-charged macroions attract each other as a result of strong electrostatic correlations in the presence of multivalent counterions or at low temperatures.

Large-parameter asymptotics of generalized Hastings–McLeod functions
NonlinearityAbstract The generalized Hastings–McLeod solutions to the inhomogeneous Painlevé-II equation arise in multi-critical unitary random matrix ensembles, the chiral two-matrix model for rectangular matrices, non-intersecting squared Bessel paths, and non-intersecting Brownian bridges on the circle.
