    Three terminal laser structure for high-speed modulation using dynamic carrier heating

    Get PDF
    A three-terminal laser structure is proposed as a means to achieve laser modulation using dynamic carrier heating. The injection of hot electrons, with energy tuned by variable joule heating over a high electric field region, is used to govern the carrier temperature in the active layer of a laser, while a separate heterojunction controls the injection rate. Simulations show the possibility of generating good-shaped picosecond optical pulses by modulating the voltage that controls the heating electric field

    13 lethal outcomes of the croupous pneumonia were analyzed. The patients’ social status and life conditions, the timeliness of taking medical advice and the completeness of emergency medical care were estimated. The Municipal Center for Ecological Pulmonology conducted this study taking into consideration objective characteristics of the environment. In authors’ opinion the long living in cities with many industrial enterprises contributed to the development of chronic respiratory diseases leading to more severe course of pneumonia and fatal outcome.Анализируется 13 случаев смерти больных от крупозной пневмонии, оценивается их социальный статус, условия быта, своевременность обращения за медицинской помощью, полнота оказания неотложной помощи. Наблюдения проводились в городском центре экологической пульмонологии, располагающем данными об объективных характеристиках среды обитания. Длительное проживание в перенасыщенном промпредприятиями городе способствовало, по мнению авторов, развитию хронических заболеваний органов дыхания, на фоне которых пневмония принимала тяжелое течение и привела к летальному исходу

    Going global or going nowhere? Chinese media in a time of flux

    Get PDF
    This article focuses on how Chinese media industries have sought to expand into new territories, identifying several mechanisms by which Chinese cultural and media products are traded and consumed: namely finished content, co-productions, formats and online platforms. The article also considers the value of overseas location shooting for domestic programmes and acquisition of international media assets. The key idea that is discussed in regards to China's outward-bound trade mission is know-how. In respect to media production, producers tend to opt for risk avoidance rather than creative exploration. Consequently, Chinese producers, investors and practitioners are deficient in knowledge of international markets and audience perceptions because the government has chosen to intervene, select and guide Chinese products. The article suggests this is gradually changing

    Efficacy Results of a Trial of a Herpes Simplex Vaccine

    Get PDF
    Two previous studies of a herpes simplex virus type 2 (HSV-2) subunit vaccine containing glycoprotein D in HSV-discordant couples revealed 73% and 74% efficacy against genital disease in women who were negative for both HSV type 1 (HSV-1) and HSV-2 antibodies. Efficacy was not observed in men or HSV-1 seropositive women

    Efficacy of the herpes zoster subunit vaccine in adults 70 years of age or older

    Background: A trial involving adults 50 years of age or older (ZOE-50) showed that the herpes zoster subunit vaccine (HZ/su) containing recombinant varicella-zoster virus glycoprotein E and the AS01B adjuvant system was associated with a risk of herpes zoster that was 97.2% lower than that associated with placebo. A second trial was performed concurrently at the same sites and examined the safety and efficacy of HZ/su in adults 70 years of age or older (ZOE-70). Methods: This randomized, placebo-controlled, phase 3 trial was conducted in 18 countries and involved adults 70 years of age or older. Participants received two doses of HZ/su or placebo (assigned in a 1:1 ratio) administered intramuscularly 2 months apart. Vaccine efficacy against herpes zoster and postherpetic neuralgia was assessed in participants from ZOE-70 and in participants pooled from ZOE-70 and ZOE-50. Results: In ZOE-70, 13,900 participants who could be evaluated (mean age, 75.6 years) received either HZ/su (6950 participants) or placebo (6950 participants). During a mean follow-up period of 3.7 years, herpes zoster occurred in 23 HZ/su recipients and in 223 placebo recipients (0.9 vs. 9.2 per 1000 person-years). Vaccine efficacy against herpes zoster was 89.8% (95% confidence interval [CI], 84.2 to 93.7; P&lt;0.001) and was similar in participants 70 to 79 years of age (90.0%) and participants 80 years of age or older (89.1%). In pooled analyses of data from participants 70 years of age or older in ZOE-50 and ZOE-70 (16,596 participants), vaccine efficacy against herpes zoster was 91.3% (95% CI, 86.8 to 94.5; P&lt;0.001), and vaccine efficacy against postherpetic neuralgia was 88.8% (95% CI, 68.7 to 97.1; P&lt;0.001). Solicited reports of injection-site and systemic reactions within 7 days after injection were more frequent among HZ/su recipients than among placebo recipients (79.0% vs. 29.5%). Serious adverse events, potential immune-mediated diseases, and deaths occurred with similar frequencies in the two study groups. Conclusions: In our trial, HZ/su was found to reduce the risks of herpes zoster and postherpetic neuralgia among adults 70 years of age or older. <br /
