Computational Models Describing Possible Mechanisms for Generation of Excessive Beta Oscillations in Parkinson's Disease.

open access: yesPLoS Computational Biology, 2015
In Parkinson's disease, an increase in beta oscillations within the basal ganglia nuclei has been shown to be associated with difficulty in movement initiation.

Mock community experiments can inform on the reliability of eDNA metabarcoding data: a case study on marine phytoplankton

open access: yesScientific Reports, 2023
Environmental DNA metabarcoding is increasingly implemented in biodiversity monitoring, including phytoplankton studies. Using 21 mock communities composed of seven unicellular diatom and dinoflagellate algae, assembled with different composition and ...

Hydrocracking of Fischer–Tropsch Paraffin Mixtures over Strong Acid Bifunctional Catalysts to Engine Fuels

open access: yesACS Omega, 2020
Biomass-based Fischer–Tropsch paraffin mixtures, having C16–C46 and C11–C45 carbon number range, were hydrocracked over platinum-supported beta, ZSM-5, and mordenite catalysts.

Exploring the Photon-Number Distribution of Bimodal Microlasers with a Transition Edge Sensor [PDF]

open access: yesPhysical Review Applied, 2017
A photon-number resolving transition edge sensor (TES) is used to measure the photon-number distribution of two microcavity lasers. The investigated devices are bimodal microlasers with similar emission intensity and photon statistics with respect to the

A STABLE, ACCURATE METHODOLOGY FOR HIGH MACH NUMBER, STRONG MAGNETIC FIELD MHD TURBULENCE WITH ADAPTIVE MESH REFINEMENT: RESOLUTION AND REFINEMENT STUDIES [PDF]

open access: yes, 2011
Performing a stable, long-duration simulation of driven MHD turbulence with a high thermal Mach number and a strong initial magnetic field is a challenge to high-order Godunov ideal MHD schemes because of the difficulty in guaranteeing positivity of the ...

Partitioning beta diversity in a tropical karst seasonal rainforest in Southern China

open access: yesScientific Reports, 2018
Both deterministic and stochastic processes have been linked to forest community assembly; however, their contribution to beta diversity has not been properly explored, and no studies to date have investigated their impacts on sparse depleted soils in ...

Electron Heating in Low-Mach-number Perpendicular Shocks. I. Heating Mechanism [PDF]

open access: yes, 2017
Recent X-ray observations of merger shocks in galaxy clusters have shown that the postshock plasma has two temperatures, with the protons hotter than the electrons.

Electron Heating in Low Mach Number Perpendicular Shocks. II. Dependence on the Pre-shock Conditions [PDF]

open access: yes, 2017
Recent X-ray observations of merger shocks in galaxy clusters have shown that the post-shock plasma is two-temperature, with the protons being hotter than the electrons.

Sudden death prevention in heart failure: The case of CIBIS III

open access: yesHeart International, 2006
CIBIS III completes a fundamental scientific phase of a sequence of large clinical trials (1-7) which has established the current therapeutic principles for the management of chronic heart failure (CHF) patients (8).

A model of neutrino mass and dark matter with large neutrinoless double beta decay

open access: yesJournal of High Energy Physics, 2017
We propose a model where neutrino masses are generated at three loop order but neutrinoless double beta decay occurs at one loop. Thus we can have large neutrinoless double beta decay observable in the future experiments even when the neutrino masses are
