This paper evaluates the effect of smoking bans in public places on the exposure to tobacco smoke of non-smokers and contrasts it with the effect of excise taxes. Exploiting data on cotininea metabolite of nicotineas well as state and time variation in anti-smoking policies across US states, we show that smoking bans in public places can perversely increase the exposure of non-smokers to tobacc...

Vanda Mimi Palmer (VMP), an orchid hybrid of Vanda tesselata and Vanda Tan Chay Yan is a highly scented tropical orchid which blooms all year round. Previous studies revealed that VMP produces a variety of isoprenoid volatiles during daylight. Isoprenoids are well known to contribute significantly to the scent of most fragrant plants. They are a large group of secondary metabolites which may po...

Censored data are quite common in statistics and have been studied in depth in the last years (for some early references, see Powell (1984), Muphy et al. (1999), Chay and Powell (2001)). In this paper we consider censored high-dimensional data. High-dimensional models are in some way more complex than their lowdimensional versions, therefore some different techniques are required. For the linea...

There is a substantial literature that examines trade-offs between money and health risks. This literature has shown that estimates of marginal willingness-to-pay (MWTP) for changes in risk can be inferred from a wide variety of market situations. Much of the work has focused on mortality risks in the labor market (W. Kip Viscusi and Joseph E. Aldy, 2003), but substantial work has also looked f...

Various physiological systems display bursting electrical activity (BEA). There exist numerous three-variable models to describe this behavior. However, higher-dimensional models with two slow processes have recently been used to explain qualitative features of the BEA of some experimentally observed systems [T. Chay and D. Cook, Math. Biosci., 90 (1988), pp. 139–153; P. Smolen and J. Keizer, J...

This paper uses novel data sets, which report both the quantity of cigarettes smoked and a measure of nicotine intake obtained from blood or saliva samples for a large and representative population over time for the UK and the US. We show that self-reported quantities, routinely used in the smoking literature, explain only a small fraction of the variance in smoking as measured by nicotine inta...

Mammalian cold thermoreceptors encode steady-state temperatures into characteristic temporal patterns of action potentials. We propose a mechanism for the encoding process. It is based on Plant's ionic model of slow wave bursting, to which stochastic forcing is added. The model reproduces firing patterns from cat lingual cold receptors as the parameters most likely to underlie the thermosensiti...

Cùng chịu ảnh hưởng của Islam giáo nhưng cộng đồng người Chăm ở Nam Bộ và Awal Trung hình thành hai sắc thái văn hóa riêng biệt bởi sự tác động yếu tố lịch sử địa hóa. Bài viết khái quát về quá trình này, từ đó đưa ra một số tương khác giữa đồng. Việc so sánh góp phần nhận dạng giá trị đặc trưng từng Việt Nam. Từ đây có thể bảo vệ, phát huy bản dân tộc theo hướng bền vững thông qua việc ứng dụn...
