Nearly deconfined spinon excitations in the square-lattice spin-1/2 Heisenberg antiferromagnet [PDF]

, 2017
We study the spin-excitation spectrum (dynamic structure factor) of the spin-1/2 square-lattice Heisenberg antiferromagnet and an extended model (the J−Q model) including four-spin interactions Q in addition to the Heisenberg exchange J.

MYC predetermines the sensitivity of gastrointestinal cancer to antifolate drugs through regulating TYMS transcription

EBioMedicine, 2019
Background: Thymidylate synthase (TYMS) is a successful chemotherapeutic target for anticancer therapy. Numerous TYMS inhibitors have been developed and used for treating gastrointestinal cancer now, but they have limited clinical benefits due to the ...

Why torus-unstable solar filaments experience failed eruption? [PDF]

, 2019
To investigate the factors that control the success and/or failure of solar eruptions, we study the magnetic field and 3-Dimensional (3D) configuration of 16 filament eruptions during 2010 July - 2013 February.

Compounds targeting YadC of uropathogenic Escherichia coli and its host receptor annexin A2 decrease bacterial colonization in bladder

EBioMedicine, 2019
Background: Uropathogenic Escherichia coli (UPEC) is the leading cause of urinary tract infections (UTIs), and fimbrial tip adhesins, play important roles in UPEC colonization.

The entropy puzzle and the quark combination model [PDF]

, 2010
We use two available methods, the Duhem-Gibbs relation and the entropy formula in terms of particle phase space distributions, to calculate the entropy in a quark combination model.

Phosphorylated Rasal2 facilitates breast cancer progression

EBioMedicine, 2019
Background: Rasal2 has diametric effects on progression of oestrogen receptor-positive (ER+) and -negative (ER–) breast cancers. The relevant causes are unknown.

Determining the Dust Extinction of Gamma-ray Burst Host Galaxies: A Direct Method Based on Optical and X-ray Photometry [PDF]

, 2008
http://link.aip.org/link/?APCPCS/1065/123/1 doi:10.1063/1.3027896We propose a straightforward method to determine the extinction of GRB host galaxies by comparing the observed optical spectra to the intrinsic ones extrapolated from the X-ray spectra.

Biological conduit small gap sleeve bridging method for peripheral nerve injury: regeneration law of nerve fibers in the conduit

Neural Regeneration Research, 2015
The clinical effects of 2-mm small gap sleeve bridging of the biological conduit to repair peripheral nerve injury are better than in the traditional epineurium suture, so it is possible to replace the epineurium suture in the treatment of peripheral ...

Use of nerve elongator to repair short-distance peripheral nerve defects: a prospective randomized study

Neural Regeneration Research, 2015
Repair techniques for short-distance peripheral nerve defects, including adjacent joint flexion to reduce the distance between the nerve stump defects, "nerve splint" suturing, and nerve sleeve connection, have some disadvantages.
