Smooth Paths on Three Dimensional Lattice
A particular class of random walks with a spin factor on a three dimensional
cubic lattice is studied. This three dimensional random walk model is a simple
generalization of random walk for the two dimensional Ising model. All critical
diffusion constants and associated critical exponents are calculated. Continuum
field theories such as Klein-Gordon, Dirac and massive Chern-Simons theories
are constructed near several critical points.Comment: 7 pages,NUP-A-94-
Clinical and epidemiological aspects of HTLV-II infection in SĂŁo Paulo, Brazil: presence of Tropical Spastic Paraparesis/HTLV-Associated Myelopathy (TSP/HAM) simile diagnosis in HIV-1-co-infected subjects Aspectos clĂnicos e epidemiolĂłgicos da infecção pelo vĂrus linfotrĂłpico de cĂ©lulas T humanas do tipo 2 (HTLV-II) em SĂŁo Paulo, Brasil: presença de paraparesia espĂĄstica tropical/mielopatia associada ao HTLV em pacientes co-infectados pelo HIV-1
In this study, the epidemiological and clinical features observed in solely HTLV-II-infected individuals were compared to those in patients co-infected with HIV-1. A total of 380 subjects attended at the HTLV Out-Patient Clinic in the Institute of Infectious Diseases "Emilio Ribas" (IIER), SĂŁo Paulo, Brazil, were evaluated every 3-6 months for the last seven years by infectious disease specialists and neurologists. Using a testing algorithm that employs the enzyme immuno assay, Western Blot and polymerase chain reaction, it was found that 201 (53%) were HTLV-I positive and 50 (13%) were infected with HTLV-II. Thirty-seven (74%) of the HTLV-II reactors were co-infected with HIV-1. Of the 13 (26%) solely HTLV-II-infected subjects, urinary tract infection was diagnosed in three (23%), one case of skin vasculitis (8%) and two cases of lumbar pain and erectile dysfunction (15%), but none myelopathy case was observed. Among 37 co-infected with HIV-1, four cases (10%) presented with tropical spastic paraparesis/HTLV-associated myelopathy (TSP/HAM) simile. Two patients showed paraparesis as the initial symptom, two cases first presented with vesical and erectile disturbances, peripheral neuropathies were observed in other five patients (13%), and seven (19%) patients showed some neurological signal or symptoms, most of them with lumbar pain (five cases). The results obtained suggest that neurological manifestations may be more frequent in HTLV-II/HIV-1-infected subjects than those infected with HTLV-II only.<br>Neste estudo, as caracterĂsticas epidemiolĂłgicas e clĂnicas observadas nos indivĂduos infectados pelo HTLV-II foram comparadas com os pacientes co-infectados com HIV-1. Um total de 380 indivĂduos atendidos na clĂnica do AmbulatĂłrio HTLV do Instituto de Infectologia "Emilio Ribas" (IIER), SĂŁo Paulo, Brasil, foram avaliados a cada 3-6 meses nos Ășltimos sete anos por especialistas em doenças infecciosas e neurologistas. Usando um algoritmo que emprega ensaio imunoenzimĂĄtico, Western Blot e reação em cadeia de polimerase, foram incluĂdos 201 (53%) pacientes infectados pelo HTLV-I e 50 (13%) infectados pelo HTLV-II. Trinta e sete (74%) eram co-infectados pelo HTLV-II e HIV-1. Dos 13 (26%) indivĂduos unicamente infectados pelo HTLV-II, infecção do trato urinĂĄrio foi diagnosticada em trĂȘs, um com vasculite e em dois casos dor lombar e disfunção erĂ©til mas nenhum caso de mielopatia foi observado. Entre 37 pacientes co-infectados com HIV-1, quatro (10%) casos apresentaram com paraparesia espĂĄstica tropical/mielopatia associada ao HTLV similar. Dois casos mostraram paraparesia como sintoma inicial, dois outros casos se apresentaram primeiramente com distĂșrbios vesical e erĂ©til e as neuropatias perifĂ©ricas foram observadas em cinco pacientes (13%). Outros sete (19%) pacientes mostraram algum sinal ou sintoma neurolĂłgico, a maioria deles com dor lombar (cinco casos). Os resultados sugerem que as manifestaçÔes neurolĂłgicas podem ser mais freqĂŒentes em indivĂduos co-infectados pelo HTLV-II/HIV-1 do que nos indivĂduos infectados somente pelo HTLV-II
Search for new resonances decaying to a or boson and a Higgs boson in the , , and channels with collisions at TeV with the ATLAS detector
See paper for full list of authors, 18 pages (plus author list + cover pages: 36 pages total), 13 figures, 1 table. Submitted to PLB. All figures including auxiliary figures are available at https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/EXOT-2015-18/International audienceA search is presented for new resonances decaying to a or boson and a Higgs boson in the , , and channels in collisions at TeV with the ATLAS detector at the Large Hadron Collider using a total integrated luminosity of 3.2 fb. The search is conducted by looking for a localized excess in the / invariant or transverse mass distribution. No significant excess is observed, and the results are interpreted in terms of constraints on a simplified model based on a phenomenological Lagrangian of heavy vector triplets
