SU(3) analysis of weak decays of doubly-heavy tetraquarks \({b\bar{c}}{q\bar{q}}\)

We study the weak decays of exotic tetraquark states \({b\bar{c}}{q\bar{q}}\) with two heavy quarks. Under the SU(3) symmetry for light quarks, these tetraquarks can be classified into an octet plus a singlet: \(3\bigotimes \bar{3}=1\bigoplus 8\). We will concentrate on the octet tetraquarks with \(J^{P}=0^{+}\), and study their weak decays, both semileptonic and nonleptonic...

Thermodynamic controls of the Western Tibetan Vortex on Tibetan air temperature

The “Western Tibetan Vortex” (WTV)—also termed the Karakoram Vortex—dominates the middle-to-lower troposphere and the near-surface air temperature variability above the western Tibetan Plateau (TP). Here, we explore the thermodynamic mechanisms through which the WTV modulates air temperature over the western TP by diagnosing the three major terms of the thermodynamic energy...

The Karakoram/Western Tibetan vortex: seasonal and year-to-year variability

, Newcastle University , Newcastle upon Tyne NE1 7RU , UK 1 Xiao-Feng Li The “Karakoram Vortex” (KV), hereafter also referred to as the “Western Tibetan Vortex” (WTV), has recently been recognized as a large

Understanding positive feedback between PNA and synoptic eddies by eddy structure decomposition method

In the upper troposphere during winter, positive synoptic eddy (SE) feedback plays an indispensible role in maintaining the Pacific–North American (PNA) pattern that dominates climate variability on inter-annual timescales over the North Pacific and downstream regions. This study shows that the eddy forcing, induced by eddy-vorticity (EV) fluxes, is not only in-phase with, but...

Preliminary clinic study on computer assisted mandibular reconstruction: the positive role of surgical navigation technique

Background The objectives of the present study were to investigate the reliability and outcomes of computer-assisted techniques in mandibular reconstruction with a fibula flap and verify whether the surgical navigation system was feasible in mandible reconstructive surgery. Methods Eight cases were enrolled in the computer assisted surgery (CAS) group and 14 cases in the...

A genistein derivative, ITB-301, induces microtubule depolymerization and mitotic arrest in multidrug-resistant ovarian cancer

Purpose To investigate the mechanistic basis of the anti-tumor effect of the compound ITB-301. Methods Chemical modifications of genistein have been introduced to improve its solubility and efficacy. The anti-tumor effects were tested in ovarian cancer cells using proliferation assays, cell cycle analysis, immunofluorescence, and microscopy. Results In this work, we show that a...
