Condensed-matter emitters offer enriched cavity quantum electrodynamical effects due to the coupling to external degrees of freedom. In the case of carbon nanotubes a very peculiar coupling between localized excitons and the one-dimensional acoustic phonon modes can be achieved, which gives rise to pronounced phonon wings in the luminescence spectrum. By coupling an individual nanotube to a tunable optical micro-cavity, we show that this peculiar exciton-phonon coupling is a valuable resource to enlarge the tuning range of the single-photon source while keeping an excellent exciton-photon coupling efficiency and spectral purity...

In order to gain further insight into the early virus-host interactions associated with highly pathogenic avian influenza virus infections in chickens, genome-wide expression profiling of chicken lung and brain was carried out at 24 and 72 h post-inoculation (h p.i.). For this purpose two recombinant H5N3 viruses were utilized, each possessing a polybasic HA0 cleavage site but differing in pathogenicity. The original rH5N3 P0 virus, which has a low-pathogenic phenotype, was passaged six times through chickens to give rise to the derivative rH5N3 P6 virus, which is highly pathogenic (Diederich S, Berhane Y, Embury-Hyatt C, Hisanaga T, Handel K et al...

Rising global temperatures are causing increases in the frequency and severity of extreme climatic events, such as floods, droughts, and heat waves. We analyze changes in summer temperatures, the frequency, severity, and duration of heat waves, and heat-related mortality in India between 1960 and 2009 using data from the India Meteorological Department. Mean temperatures across India have risen by more than 0.5°C over this period, with statistically significant increases in heat waves. Using a novel probabilistic model, we further show that the increase in summer mean temperatures in India over this period corresponds to a 146% increase in the probability of heat-related mortality events of more than 100 people...

INTRODUCTION: Tuberculosis is a major health problem worldwide. Extrapulmonary tuberculosis is often secondary to some primary foci in lungs. There are reports of tuberculous osteomyelitis involving maxilla, ulna, femur, and shoulder joint but none have reported pathological fracture in humeral diaphysis due to tuberculosis osteomyelitis without shoulder joint involvement. We report a case of pathological fracture of humerus diaphysis due to tuberculous osteomyelitis with normal articular space...

Animal models for the toxoplasmosis are scarce and have limitations. In this study, a neurological mouse model was developed in BALB/c mice infected intraperitoneally with 15 cysts of a Toxoplasma gondii isolate. The mice were monitored for 42 days and euthanized at different time points. Another group of mice were orally treated with dexamethasone (DXM: 2.66 mg/kg daily, 5.32 mg/kg daily) at 42 days after infection and monitored for a further 42 days. A mortality rate of 15% and 28.6% was observed in mice given 2...

BACKGROUND: Neocentromeres are rare and considered chromosomal aberrations, because a non-centromeric region evolves in an active centromere by mutation. The literature reported several structural anomalies of X chromosome and they influence the female reproductive capacity or are associated to Turner syndrome in the presence of monosomy X cell line. CASE PRESENTATION: We report a case of chromosome X complex rearrangement found in a prenatal diagnosis. The fetal karyotype showed a mosaicism with a 45,X cell line and a 46 chromosomes second line with a big marker, instead of a sex chromosome...

Small but timely experiences can have long-term benefits when their psychological effects interact with institutional processes. In a follow-up of two randomized field experiments, a brief values affirmation intervention designed to buffer minority middle schoolers against the threat of negative stereotypes had long-term benefits on college-relevant outcomes. In study 1, conducted in the Mountain West, the intervention increased Latino Americans' probability of entering a college readiness track rather than a remedial one near the transition to high school 2 y later...

In quantum field theory, Lorentz invariance leads to three types of fermion-Dirac, Weyl and Majorana. Although the existence of Weyl and Majorana fermions as elementary particles in high-energy physics is debated, all three types of fermion have been proposed to exist as low-energy, long-wavelength quasiparticle excitations in condensed-matter systems. The existence of Dirac and Weyl fermions in condensed-matter systems has been confirmed experimentally, and that of Majorana fermions is supported by various experiments...

This study represents the first example of a manganese-catalyzed environmentally benign, practical three-component aminomethylation of activated aromatic compounds including naphtols, phenols, pyridines, indoles, carbazoles, and thiophenes in combination with amines and MeOH as a C1 source. These reactions proceed with high atom efficiency via a sequence of dehydrogenation and condensation steps which give rise to selective C-C and C-N bond formations, thereby releasing hydrogen and water. A well-defined hydride Mn(I) PNP pincer complex, recently developed in our laboratory, catalyzes this process in a very efficient way, and a total of 28 different aminomethylated products were synthesized and isolated yields of up to 91%...

BACKGROUND: The global prevalence of type 2 diabetes mellitus (T2DM) is high and is increasing in countries undergoing rapid socio-economic development, including Thailand. Sugar-sweetened beverage (SSB) intake may contribute to the risk of developing T2DM. However, few studies have assessed this association in Asian populations, and the results have been inconsistent. We aimed to assess that association in a prospective study of Thai adults. METHODS: Data were from Thai Cohort Study participants surveyed in 2005, 2009 and 2013...

Why do great powers with benign intentions end up fighting each other in wars they do not seek? We utilize an incentivized, two-person "Preemptive Strike Game" (PSG) to explore how the subjective perception of great power interdependence shapes defensive aggression against persons from rival great powers. In Study 1, college students from the United States (N = 115), China (N = 106), and Japan (N = 99) made PSG decisions facing each other. This natural experiment revealed that Chinese and Japanese participants (a) made more preemptive attacks against each other and Americans than against their compatriots, and that (b) greater preexisting perceptions of bilateral competition increased intergroup attack rates...

Three recurring hypothesis are often used to explain the effect of non-thermal plasma (NTP) on NTP-catalytic hybrid reactions, namely, modification or heating of the catalyst or the ability of plasma produced species to open up new reaction pathways. By directly monitoring the catalyst by X-ray absorption fine structure (XAFS) coupled with end of pipe mass spectrometry the NTP assisted CH4 oxidation over Pd/Al2O3 was investigated. This in situ study has shown that the catalyst did not undergo any significant structural changes under NTP conditions...
