Like-sign Di-lepton Signals in Higgsless Models at the LHC

We study the potential LHC discovery of the Z1 KK gauge boson unitarizing longitudinal W+W- scattering amplitude. In particular, we explore the decay mode Z1->t tbar along with Z1-> W+W- without specifying the branching fractions. We propose to exploit the associated production pp-> W Z1, and select the final state of like-sign dileptons plus multijets and large missing energy. We conclude that it is possible to observe the Z1 resonance at a 5 sigma level with an integrated luminosity of 100 inverse fb at the LHC upto 650 GeV for a dominant WW channel, and 560 GeV for a dominant ttbar channel.Comment: 13 pages, 7 figure

关于我国社会资本办医疗机构的分析与思考*

This paper mainly described the current situation of the medical institutions of social capital in our country, analyzed the existing problems, and put forward suggestions for improvement to further promote the medical institutions held by social capital. We should make reasonable set of private medical institutions,  promote the flow of talent,  create a fair market environment, strengthen supervision and management of private hospitals and other aspects of reform, make efforts to promote the process of social capital to do medicine and to provide better health services for people.本文主要叙述了我国社会资本举办医疗机构的现阶段状况，并对社会资本办医存在的问题进行剖析思考，为进一步推进社会资本举办医疗机构提出改进建议。认为要从合理设置民营医疗机构、推动人才流动、营造公平良好的市场环境、加强对民营医院的监督管理等方面进行改革，努力推进我国社会资本办医进程，为人民提供更优质的医疗卫生服务

6-Amino-8-(2-bromo­phen­yl)-1,7,8,8a-tetrahydro-3H-isothio­chromene-5,7,7-tricarbonitrile dimethyl­formamide solvate

In the title compound, C18H13BrN4S·C3H7NO, the thio­pyran ring and the adjacent six-numbered ring adopt distorted boat conformations. The mol­ecules, lying about inversion centers, form hydrogen-bonded dimers involving one of the H atoms on the amino group with the N atom of a cyano group of an adjacent mol­ecule, resulting in a 12-membered ring system [R 2 2(12) ring motif]. The other H atom of the amino group forms an inter­molecular hydrogen bond with the O atom of the dimethyl­formamide (DMF) mol­ecule. Another lone pair of electrons on the same carbonyl O atom of DMF mol­ecule forms a non-classical C—H⋯O inter­molecular hydrogen bond, resulting in a chain of mol­ecules

(S,Z)-1-Chloro-3-[(3,4,5-trimeth­oxy­benzyl­idene)amino]­propan-2-ol

In the title compound, C13H18ClNO4, the two meth­oxy groups at the meta positions of the attached benzene ring are close to being coplanar with the ring [the meth­oxy C atoms deviate by 0.267 (7) and 0.059 (7) Å], whereas the third meth­oxy group at the para position is not coplanar with the benzene ring [methoxy C atom deviates by 1.100 (6) Å]. In the crystal, mol­ecules are linked into a chain along the a axis by O—H⋯N hydrogen bonds

Landau levels and magnetopolaron effect in dilute GaAs:N

The magnetic-field dependence of the energy spectrum of GaAs doped with nitrogen impurities is investigated. Our theoretical model is based on the phenomenological Band Anticrossing Model (BAC) which we extended in order to include magnetic field and electron - phonon interaction. Due to the highly localized nature of the nitrogen state, we find that the energy levels are very different from those of pure GaAs. The polaron correction results in a lower cyclotron resonance energy as compared to pure GaAs. The magneto-absorption spectrum exhibits series of asymmetric peaks close to the cyclotron energy

Effect of Native Defects on Optical Properties of InxGa1-xN Alloys

The energy position of the optical absorption edge and the free carrier populations in InxGa1-xN ternary alloys can be controlled using high energy 4He+ irradiation. The blue shift of the absorption edge after irradiation in In-rich material (x > 0.34) is attributed to the band-filling effect (Burstein-Moss shift) due to the native donors introduced by the irradiation. In Ga-rich material, optical absorption measurements show that the irradiation-introduced native defects are inside the bandgap, where they are incorporated as acceptors. The observed irradiation-produced changes in the optical absorption edge and the carrier populations in InxGa1-xN are in excellent agreement with the predictions of the amphoteric defect model

Genes related to the very early stage of ConA-induced fulminant hepatitis: a gene-chip-based study in a mouse model

<p>Abstract</p> <p>Background</p> <p>Due to the high morbidity and mortality of fulminant hepatitis, early diagnosis followed by early effective treatment is the key for prognosis improvement. So far, little is known about the gene expression changes in the early stage of this serious illness. Identification of the genes related to the very early stage of fulminant hepatitis development may provide precise clues for early diagnosis.</p> <p>Results</p> <p>Balb/C mice were used for ConA injection to induce fulminant hepatitis that was confirmed by pathological and biochemical examination. After a gene chip-based screening, the data of gene expression in the liver, was further dissected by ANOVA analysis, gene expression profiles, gene network construction and real-time RT-PCR.</p> <p>At the very early stage of ConA-triggered fulminant hepatitis, totally 1,473 genes with different expression variations were identified. Among these, 26 genes were finally selected for further investigation. The data from gene network analysis demonstrate that two genes, MPDZ and Acsl1, localized in the core of the network.</p> <p>Conclusions</p> <p>At the early stages of fulminant hepatitis, expression of twenty-six genes involved in protein transport, transcription regulation and cell metabolism altered significantly. These genes form a network and have shown strong correlation with fulminant hepatitis development. Our study provides several potential targets for the early diagnosis of fulminant hepatitis.</p
