Does the Borexino experiment have enough resolution to detect the neutrino flavor day-night asymmetry?

open access: yes, 2013
The Earth's density distribution can be approximately considered piecewise continuous at the scale of two-flavor oscillations of neutrinos with energies about 1 MeV.

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

open access: yesConservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Mechanisms underlying the protective effects of San‐Bai decoction against UV radiation on the skin

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Combining conventional differential expression analysis with differential network analysis offers a promising strategy to uncover the mechanistic basis of the holistic benefits provided by herbal blends. Our findings demonstrated that San‐Bai decoction modulates multiple pathways—not only those related to skin pigmentation, such as ET‐1 signalling, but

Link invariants via counting surfaces

open access: yes, 2013
A Gauss diagram is a simple, combinatorial way to present a knot. It is known that any Vassiliev invariant may be obtained from a Gauss diagram formula that involves counting (with signs and multiplicities) subdiagrams of certain combinatorial types ...

Health Outcomes in Children and Adolescents With Overweight or Obesity Exposed to Physical Activity Interventions: An Umbrella Review Covering Over 1200 Trials

open access: yesObesity Reviews, EarlyView.
ABSTRACT Childhood and adolescent obesity poses health risks. Standardizing outcome measurements in physical activity interventions enhances evidence comparability. This study summarizes health outcomes reported in systematic reviews and classifies them under an existing taxonomy as a preliminary step toward the future development of a core outcome set.
