Gray Matter Volume Loss in Parkinson's Disease Psychosis and Cannabinoid Receptor Gene Expression in the Brain

Movement Disorders, EarlyView.
Abstract Background Serotonergic and dopaminergic pathways are implicated in Parkinson's disease psychosis (PDP), but preliminary evidence also implicates the endocannabinoid system (ECS). Objectives We examined the association of gray matter volume loss in PDP patients with brain expression of the genes coding for CB1 (cannabinoid type 1) and CB2 ...

Greater future range expansions in alien than native ant species

Oikos, EarlyView.
There is growing concern that many species may not be able to track suitable conditions under climate change and suffer range contractions as a result. At the same time, alien species introduced to novel geographic ranges are often assumed to benefit from climate change.

Time-Dependent Partition-Free Approach in Resonant Tunneling Systems

, 2004
An extended Keldysh formalism, well suited to properly take into account the initial correlations, is used in order to deal with the time-dependent current response of a resonant tunneling system.

Herbarium digitisation sheds light on historical distribution and drivers of population extinction of a peat bog specialist

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity loss threatens ecosystem services and human well‐being. Understanding the extent and causes of changes in biodiversity over time can help protect species and their habitats. Herbaria house carefully documented and curated specimens collected by generations of botanists.

DIVE in the cosmic web: voids with Delaunay Triangulation from discrete matter tracer distributions

, 2015
We present a novel parameter-free cosmological void finder (\textsc{dive}, Delaunay TrIangulation Void findEr) based on Delaunay Triangulation (DT), which efficiently computes the empty spheres constrained by a discrete set of tracers.

Biodiversity science is improved when silent herbaria speak

PLANTS, PEOPLE, PLANET, EarlyView.
Herbaria in the Global South are critical yet underutilized resources for biodiversity science and often absent from international databases and research networks. We highlight the phenomenon of “silent herbaria” using Nigeria as a case study and quantify how these collections fill important gaps in global biodiversity knowledge.

Measurement of the neutral D meson mixing parameters in a time-dependent amplitude analysis of the D^0→π^+π^−π^0 decay [PDF]

, 2016
We perform the first measurement on the D^0−D^0 mixing parameters using a time-dependent amplitude analysis of the decay D^0→π^+π^−π^0. The data were recorded with the BABAR detector at center-of-mass energies at and near the Υ(4S) resonance, and ...

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...
