Time-resolved charge detection in graphene quantum dots

open access: yes, 2011
We present real-time detection measurements of electron tunneling in a graphene quantum dot. By counting single electron charging events on the dot, the tunneling process in a graphene constriction and the role of localized states are studied in detail ...

Genome‐Wide Assessment Reveals Ancestral Differences in Homozygosity Patterns Potentially Linked to Parkinson's Disease Etiology

open access: yesMovement Disorders, EarlyView.
Abstract Background Recessive genetic variation and extended runs of homozygosity (ROHs) may contribute to the unexplained heritability of Parkinson's disease (PD), particularly in diverse and understudied populations. Objective We conducted the first large‐scale, multi‐ancestral investigation of PD to examine the impact of genome‐wide homozygosity on ...

Adaptive Deep Brain Stimulation for Parkinson's Disease: Navigating the Roadblocks to Clinical Implementation

open access: yesMovement Disorders, EarlyView.
Abstract Adaptive deep brain stimulation (aDBS) represents an important evolution in the treatment of Parkinson's disease (PD), building on conventional DBS (cDBS) by adjusting stimulation in response to real‐time physiological signals. By enabling dynamic targeting of disease‐related neural activity, aDBS offers the potential for more precise ...

Numerical precision radiative corrections to the Dalitz plot of baryon semileptonic decays including the spin-momentum correlation of the decaying and emitted baryons

open access: yes, 2004
We calculate the radiative corrections to the angular correlation between the polarization of the decaying and the direction of the emitted spin one-half baryons in the semileptonic decay mode.

From Connections to Actions: When Do Government Ties Matter to Nonprofit Organizational Performance?

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT Nonprofit organizations are essential for public service delivery, yet the value of their government ties is contested. This study examines the mechanism that translates these connections into tangible results. We propose that political networking—the deliberate cultivation and use of official relationships—is the critical catalyst.

Connecting tradition and technology: The digitization of the ethnobotanical collection at the Rio de Janeiro Botanical Garden

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The digitization of RBetno (JBRJ) represents a step forward for biodiversity conservation in Brazil. Aligned with the Kunming‐Montreal Global Biodiversity Framework (Target 2, 2020–2030), this project documents the use of plants, including traditional knowledge and vernacular names, with a focus on the Atlantic Forest and Amazon.

An elementary proof of Small's formula for null curves in PSL(2,C) and an analogue for Legendrian curves in PSL(2,C) [PDF]

open access: yes, 2003
For null curves in PSL(2,C), there exists a representation formula in terms of two meromorphic functions and their derivatives (Small's formula). In this paper, we give an elementary proof of Small's formula.

Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

open access: yesPest Management Science, EarlyView.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the
