Development stage‐dependent effects of biodiversity on aboveground biomass of temperate forests

open access: yesEcography, Volume 2025, Issue 4, April 2025.
Increasing evidence shows that biodiversity–ecosystem functioning relationships (BEFs) become stronger as forests develop, but much of the evidence is drawn from experiments (less than 30 years). How the biodiversity effects vary with stand development stages remains largely unexplored.

Super Efimov effect of resonantly interacting fermions in two dimensions

open access: yes, 2013
We study a system of spinless fermions in two dimensions with a short-range interaction fine-tuned to a p-wave resonance. We show that three such fermions form an infinite tower of bound states of orbital angular momentum l=\pm1 and their binding ...

Generic Revision of the Southeast and East Asian Torrent Carp Subfamily Acrossocheilinae (Pisces: Teleostei) With Description of Three New Genera and a New Species From Vietnam

open access: yesJournal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.
Molecular data from 35 of the 50 Acrossocheilinae species suggest that the species‐level diversity in the subfamily has been overestimated, likely due to inadequate taxon and geographic sampling and reliance on morphological characters that vary intraspecifically. Three new genera, one resurrected genus, two resurrected species, and one new species are

Dynamical mean-field approximation for unitary Fermi gas

open access: yes, 2008
Dynamical mean-field approximation with explicit pairing is utilized to study the properties of a two-component Fermi gas at unitarity. The problem is approximated by the lattice Hubbard Hamiltonian, and the continuum limit is realized by diluting the ...

Collective Excitations of Harmonically Trapped Ideal Gases

open access: yes, 2008
We theoretically study the collective excitations of an ideal gas confined in an isotropic harmonic trap. We give an exact solution to the Boltzmann-Vlasov equation; as expected for a single-component system, the associated mode frequencies are integer ...

Radiomics Based on Multimodal magnetic resonance imaging for the Differential Diagnosis of Benign and Malignant Vertebral Compression Fractures

open access: yesOrthopaedic Surgery, Volume 16, Issue 10, Page 2464-2474, October 2024.
Radiomics for differentially diagnosing VCF Objectives Recent studies have indicated that radiomics may have excellent performance and clinical application prospects in the differential diagnosis of benign and malignant vertebral compression fractures (VCFs).

Crossover from 2D to 3D in a weakly interacting Fermi gas

open access: yes, 2011
We have studied the transition from two to three dimensions in a low temperature weakly interacting $^6$Li Fermi gas. Below a critical atom number, $N_{2D}$, only the lowest transverse vibrational state of a highly anisotropic oblate trapping potential ...

Intensive mannitol slow infusion post‐stenting may attenuate stenting‐related early adverse effects in patients with cerebral venous sinus stenosis

open access: yesCNS Neuroscience &Therapeutics, Volume 30, Issue 2, February 2024.
Stenting may induce temporarily severe headache, abnormal elevated inflammatory biomarkers, and brain edema aggravation especially in local area surround the stent and even intracranial hemorrhage in the early period post‐stenting. Short‐term extra intensive mannitol slow infusion may effectively attenuate stenting‐related early adverse effects ...

Topological superfluid of spinless Fermi gases in p-band honeycomb optical lattices with on-site rotation

open access: yes, 2012
In this paper, we put forward to another route realizing topological superfluid (TS). In contrast to conventional method, spin-orbit coupling and external magnetic field are not requisite.

Topological quantum phase transitions of attractive spinless fermions in a honeycomb lattice

open access: yes, 2011
We investigate a spinless Fermi gas trapped in a honeycomb optical lattice with attractive nearest-neighbor interactions. At zero temperature, mean-field theory predicts three quantum phase transitions, two being topological.
