Elastic light-scattering modulator: A concept

Simple structure can be used as electrically-controlled light valve, to scatter both transmitted and reflected beams. Its operation is based on physical phenomenon called frosting. Device may be of interest to manufacturers of page composers, alphanumeric displays, flat-panel displays, large-screen televisions, and optical input terminals for computers

Beyond trauma? memories of Joi/y and memory play in Blade Runner 2049

Cultural memory studies finds itself at an impasse: whereas ‘cultural memory’ is conceptualized as mediated, dynamic, imaginative and shaped by the present, the dominant paradigm of ‘trauma’ illuminates the hold the past has on us, casting the shadow of a melancholic subjectivity that threatens to obscure our agency as (political) subjects. This article asks what lies in store for memory studies beyond the focus on (classic) trauma (theory). Using the movie Blade Runner 2049 (US 2017; dir: Denis Villeneuve) as an illustrative example, it explores how creative and joyful forms of meaning-making through play and acts of memory inform each other in what the psychoanalyst DW Winnicott described as ‘cultural experience’

Chinese New Migrants in Czeth and Slovakia: A Preliminary Observation and Study

An ideal ultrasonic transducer will be one which responds accurately to an ultrasonic waveform. Information contained within the original waveform should be easily obtained from the output of such a transducer. This will require the transducer to have a number of characteristics: (1) Wide bandwidth — for some measurements response up to 10MHz is required. (2) High sensitivity — gives the ability to detect defects at a distance. (3) Low distortion of waveform — preferably non-contacting to avoid loading the acoustic wave. (4) Practicality

Promoting smoking cessation among the elderly: What are the predictors of intention to quit and successful quitting?

Purpose: To assess the predictors of smoking cessation and intention to quit among the Chinese elderly smokers. Design: A cross-sectional survey of elderly smokers. Setting: Shamsuipo district, Hong Kong. Subject: A total of 1,318 elderly were interviewed (response rate = 83%). Measures: A structured questionnaire was used for data collection. The questionnaire sought information on the subject's sociodemographic background and smoking habits. The predictors for successful quitting and intention to quit were assessed by chi-square tests and multiple logistic regression. Results: Of the respondents, 20.2% were current smokers, 25.4% were ex-smokers, and 54.4% were never smokers. Of the smoker (current and ex-smokers) respondents, 55.7% (335/601) had successfully quit at the time of enumeration. The predictors of quitting were living with others, receiving assistance for mobility, being nondrinkers, smoking for shorter duration, and smoking more cigarettes per day. Having health problems in the past, smoking for shorter duration, and smoking fewer cigarettes per day were predictors of intention to quit smoking. Conclusion: The study identified several predictors of successful quitting that could help improve the provision of current smoking cessation services. Population-based smoking cessation programs, especially those targeted to elderly, should take these predictors into consideration in the design of interventions. © 2006 Sage Publications.link_to_subscribed_fulltex
