Analysis of longwave radiation for the Earth-atmosphere system

Accurate radiative transfer models are used to determine the upwelling atmospheric radiance and net radiative flux in the entire longwave spectral range. The validity of the quasi-random band model is established by comparing the results of this model with those of line-by-line formulations and with available theoretical and experimental results. Existing radiative transfer models and computer codes are modified to include various surface and atmospheric effects (surface reflection, nonequilibrium radiation, and cloud effects). The program is used to evaluate the radiative flux in clear atmosphere, provide sensitivity analysis of upwelling radiance in the presence of clouds, and determine the effects of various climatological parameters on the upwelling radiation and anisotropic function. Homogeneous and nonhomogeneous gas emissivities can also be evaluated under different conditions

Investigating the generalizability of EEG-based Cognitive Load Estimation Across Visualizations

We examine if EEG-based cognitive load (CL) estimation is generalizable across the character, spatial pattern, bar graph and pie chart-based visualizations for the nback~task. CL is estimated via two recent approaches: (a) Deep convolutional neural network, and (b) Proximal support vector machines. Experiments reveal that CL estimation suffers across visualizations motivating the need for effective machine learning techniques to benchmark visual interface usability for a given analytic task

Discosiella Sydow and Discosiellina gen. nov.

Discosiella cylindrospora H. and P. Sydow, the type species of the genus Discosiella H. and P. Sydow, is redescribed from a study of type material. It is concluded that the conidial appendages of this fungus are mucoid in nature, a fact not mentioned by the Sydows in their diagnosis and description. The diagnosis of Discosiella is suitably emended. From the original description of D. longiciliata Agnihothrudu, supplemented by a study of the type material of this species, it is concluded that it cannot be retained in the genus Discosiella as emended in this paper and is now accommodated in a new genus Discosiellina as D. longiciliata (Agnihothrudu) comb. nov

Price Elasticity of Demand for Term Life Insurance and Adverse Selection

This paper provides an empirical estimate of price' and risk' elasticities of demand for term life insurance for those who purchase some insurance. It finds that the elasticity with respect to changes in premiums is generally higher than the elasticity with respect to changes in risk. It also finds that the elasticity, in the range of -0.3 to -0.5, is sufficiently low that adverse selection in term life insurance is unlikely to lead to a death spiral and may not even lead to measured effects of adverse selection on total purchases.

Tropical mycology and biotechnology

The relevance of tropical mycology to biotechnology rests on mycodioersity and the enormous fungal power that such mycodioersit.y implies. The strateqies, techniques and priorities in harnessing fungal power for human needs are outlined. The author explains the urgent need Jar a Jungal inventory oj the tropics, for a combing of special microhabitats and ecological niches for mycogenomes, the maintenance in culture and conservation of these genomes and the study oj their secondary metabolites and other attributes, and co-evolution with other genomes. These genomes are irreplaceable and must therefore be conserved
