Stereoscopic depth aftereffects without retinal position correspondence between adaptation and test stimuli

AbstractTo clarify whether stereo-slant aftereffects are independent of stimulated retinal position, two experiments compared the magnitude of aftereffects between the following two conditions: when the adaptation and test stimulus fell on (1) the same retinal position, and (2) on different retinal positions separated by 0.5°–20°. In Experiment 1, disc- or ring-shaped surface consisting of random-dots was presented at the central or peripheral visual fields. In Experiment 2, rectangular surface was presented at the upper or lower visual fields. After two minutes inspection of a random-dot stereogram depicting a ±30° slanted surface, the observer adjusted the slant of the test stimulus to appear fronto-parallel. The results of the experiments showed that significant aftereffects were observed similarly in both conditions. Moreover, the separation nor the stimulus shape scarcely affected the magnitude of the aftereffects. Based on these results we concluded that the depth processing mechanism which operates independently from the stimulated retinal position is responsible for the depth aftereffects we found

Scale dependent bias from primordial non-Gaussianity with trispectrum

We study the scale dependent bias of the halo power spectrum arising from primordial non-Gaussianity. We present an analytic result of the halo bias including up to the trispectrum contributions. We find the scale dependent bias opens a new possibility of probing the relation between the non-linearity parameters \fnl and \tnl.Comment: 5 pages, 3 figures, submitted to MNRA

The Internationalization of Japanese Firms: New Findings Based on Firm-Level Data

Using firm-level data for the Japanese manufacturing sector, we examine characteristics of internationalized firms, i.e., firms engaging in export and/or foreign direct investment (FDI), and compare these characteristics with those for selected European countries. We find that internationalized firms are a few and that their productivity is higher than that of non-internationalized firms, confirming the findings of existing studies on Japan and other countries. In addition, we find that productivity differences between non- internationalized firms, exporters, and FDI firms are substantially smaller in Japan than in the European countries. This evidence suggests that productivity differences alone cannot determine export or FDI behavior of Japanese firms.

Степенные законы для матриц обратного рассеяния при лидарном зондировании перистых облаков

Показано, что банк данных матриц обратного рассеяния для ледяных кристаллов перистых облаков, рассчитанный авторами доклада и выставленный в интернет для свободного доступа, в случае хаотически ориентированных кристаллов может быть заменен простыми аналитическими выражениями. Рассчитаны значения четырех микрофизических отношений, измеряемых лидарами, в зависимости от формы и эффективных размеров кристаллов. Эти величины можно использовать для диагностики формы кристаллов в перистых облака

A non-carboxylating pentose bisphosphate pathway in halophilic archaea

Bacteria and Eucarya utilize the non-oxidative pentose phosphate pathway to direct the ribose moieties of nucleosides to central carbon metabolism. Many archaea do not possess this pathway, and instead, Thermococcales utilize a pentose bisphosphate pathway involving ribose-1, 5-bisphosphate (R15P) isomerase and ribulose-1, 5-bisphosphate (RuBP) carboxylase/oxygenase (Rubisco). Intriguingly, multiple genomes from halophilic archaea seem only to harbor R15P isomerase, and do not harbor Rubisco. In this study, we identify a previously unrecognized nucleoside degradation pathway in halophilic archaea, composed of guanosine phosphorylase, ATP-dependent ribose-1-phosphate kinase, R15P isomerase, RuBP phosphatase, ribulose-1-phosphate aldolase, and glycolaldehyde reductase. The pathway converts the ribose moiety of guanosine to dihydroxyacetone phosphate and ethylene glycol. Although the metabolic route from guanosine to RuBP via R15P is similar to that of the pentose bisphosphate pathway in Thermococcales, the downstream route does not utilize Rubisco and is unique to halophilic archaea
