Journal of Behavioral and Brain Science (JBBS) , 2018, DOI: 10.4236/jbbs.2018.84013
Abstract: The purpose of this study was to investigate whether the opinions of people eating together affect the taste of the foods they eat. In addition, if the opinions of others influence taste for one of the people eating with them, are the others’ opinions related to the empathy of individuals? Finally, this study was also intended to consider whether the taste threshold changes depending on the opinions of others. Twelve healthy young women (aged 18.4 ± 0.8 years; mean ± SD) participated in the present study. The participants tasted bread under three conditions: 1) quiet condition: a participant ate with three quiet persons, 2) positive condition: a participant ate with three persons who were talking favorably about taste, and 3) negative condition: a participant ate with three persons who were talking negatively about the taste. The electrical taste threshold was tested before and after tasting the bread, and a visual analog scale (VAS) was completed immediately after the tasting. Before the first trial, participants were asked to complete the Interpersonal Reactive Index (IRI). In the positive condition, the taste score increased significantly compared with the negative condition. There was no significant relationship between taste and empathic concern. To our knowledge, taste changed according to the comments of other people who were eating together. However, the change in taste due to the other’s speech was not related to the individual’s empathy. The results of the present study suggest that people experience food as delicious when others eating with them comment about the food being “delicious,” and this tendency did not depend on individuals’ empathy.

Journal of Behavioral and Brain Science (JBBS) , 2019, DOI: 10.4236/jbbs.2019.93013
Abstract: Communal eating reportedly induces changes in food-related behaviors such as increased consumption and alleviation of indefinite complaints. Here, we examined the influence of intimacy with co-eaters on the palatability of the food and the physiological taste thresholds. The study was a single-blind crossover trial with 16 healthy women aged 18 - 19 years (two close friends × 8) as participants. We examined the effect of four preset conditions with regard to taste (condition 1 = tasting alone; condition 2 = tasting with a friend; condition 3 = tasting with three unfamiliar individuals; condition 4 = tasting with a friend and two unfamiliar individuals). Electrical taste thresholds were measured pre-and post-eating. The subjective evaluation of taste did not show any significant difference between the four conditions (p > 0.05). However, the electrical taste threshold significantly decreased when eating with close friends (p < 0.05). As a factor associated with the meal environment, co-eating with family or friends appears to influence tastiness; however, in the present study, it showed no effect on the perception of taste. Nevertheless, eating with friends significantly decreased the electrical taste threshold and enhanced the perception of taste. Decrease in the electrical taste threshold was observed only when eating with a close friend; it was not observed when eating with other people and showed no association with the total number of individuals co-eating.

Abstract: Tobacco is one of the risk factors for non-communicable disease. The Philippines’s smoking rate of aged 15 years and older is 23.8%, which is high in Asian countries. This study aimed to investigate whether older persons’ smoking habits are associated with lower self-rated health (SRH) and advocate for policy amendment in the Philippines. This research conducted a cross-sectional study on 300 eligible?Filipinos aged 60 and over living in Metro Manila, Quezon City, from November 2012 to March 2013. The number of effective answers was 300. Demographic and SRH data were collected. Binary regression analyses and logistic regression models were used for this analysis after testing for “multicollinearity”. In total, 40.33% of older persons perceived higher self-rated health; 14.00% of them had a smoking habit, and 24.67% of them drank alcohol. A multivariable analysis showed that the factors associated with better SRH among older persons in this study were more total education years, fewer total number of symptoms, longer sleep hours, more cigarettes per day, more alcohol consumption per day, having friends and having medical insurance. In agreement with previous studies, education, symptoms, sleep, alcohol, social networks, and insurance were associated with SRH. Regarding the relation between tobacco and SRH, there were two different outcomes. This research showed a positive association between tobacco and SRH. Not having universal coverage of medical insurance to address health concerns and a social custom of selling tobacco were associated with a positive relation between tobacco and SRH. Amendment of tobacco policies to expand health insurance and to limit selling tobacco in the street might help modify the SRH of older persons in the Philippines.
Detection of Oxidized Ferrocenes by LC-MS with Electrospray Ionization Using Picric Acid as the Counter Ion  [PDF]
Yutaka Okada, Masako Tsuchida
International Journal of Analytical Mass Spectrometry and Chromatography (IJAMSC) , 2019, DOI: 10.4236/ijamsc.2019.71001
Abstract: Ferrocene is an organometallic compound that readily undergoes oxidation in atmosphere under acidic conditions. However, because of its diamagnetic nature, ferrocene does not lend itself to structural analysis by nuclear magnetic resonance (NMR) spectroscopy. In this work, the oxidation of ferrocene and several of its derivatives were analyzed by liquid chromatography-mass spectrometry (LC-MS). An electrospray ionization (ESI) source was used, with picrate serving as the counter ion. This method is particularly effective for studying oxidation of ferrocenes because their reactivity toward oxygen under ambient conditions is low.
Light Curves of GRB Optical Flashes
Shiho Kobayashi
Physics , 2000, DOI: 10.1086/317869
Abstract: The standard model of GRB afterglows assumes that relativistically expanding material is decelerating due to interaction with the surrounding medium. The afterglows are well described by the synchrotron radiation from a forward shock, while the strong optical flash associated with GRB 990123 can be attributed to the emission from a reverse shock. We give a detailed study on the reverse shock emission. The full light curves are calculated for a long and a short GRB cases. We discuss the lack of the prompt optical detections by ROTSE for GRB 981121 and GRB 981223.

Mathematics , 2007,
Abstract: In this paper, we develop the theory of relative log convergent cohomology. We prove the coherence of relative log convergent cohomology in certain case by using the comparison theorem between relative log convergent cohomlogy and relative log crystalline cohomology, and we relates relative log convergent cohomology to relative rigid cohomology to show the validity of Berthelot's conjecture on the coherence and the overconvergence of relative rigid cohomology for proper smooth families when they admit nice proper log smooth compactification to which the coefficient extends logarithmically.

Atsushi Shiho
Mathematics , 2007,
Abstract: In this paper, we develop the theory of relative log convergent cohomology of radius $\lambda$ ($0 < \lambda \leq 1$), which is a generalization of the notion of relative log convergent cohomology in the previous paper. By comparing this cohomology with relative log crystalline cohomology, relative rigid cohomology and its variants and by using some technique of hypercovering, we prove a version of Berthelot's conjecture on the overconvergence of relative rigid cohomology for proper smooth families.

Abstract: In this paper, we prove the generic overconvergence of relative rigid cohomology with coefficient, by using the semistable reduction conjecture for overconvergent $F$-isocrystals (which is recently shown by Kedlaya).

Cut-by-curves criterion for the log extendability of overconvergent isocrystals
Atsushi Shiho
Mathematics , 2009,
Abstract: In this paper, we prove a `cut-by-curves criterion' for an overconvergent isocrystal on a smooth variety over a field of characteristic $p>0$ to extend logarithmically to its smooth compactification whose complement is a strict normal crossing divisor, under certain assumption. This is a $p$-adic analogue of a version of cut-by-curves criterion for regular singuarity of an integrable connection on a smooth variety over a field of characteristic 0. In the course of the proof, we also prove a kind of cut-by-curves criteria on solvability, highest ramification break and exponent of $\nabla$-modules.
