Satiety Relaxes Thinness Criteria When Judging Others’ Body Shapes  [PDF]
Naoto Sato, Kasumi Suzuki, Kenichi Shibuya
Journal of Behavioral and Brain Science (JBBS) , 2018, DOI: 10.4236/jbbs.2018.84011
Abstract: While people might endorse tolerance, social/environmental biases can remain operative and drive action in an unconscious manner. Herein, we investigated whether the criteria for judging others’ body shapes as “fat” or “thin” change with the degree of satiety. Nine females participated in the present study. The participants judged nine women’s figures as fat or skinny on a computer monitor in two conditions (Fasting and Satiety). Each figure ranged in body mass index (BMI) from 18.3 to 45.4 (i.e., 18.3, 19.3, 20.9, 23.1, 26.2, 29.9, 34.3, 38.6, and 45.4). Parameter estimates showed that a one-unit change in condition (Fasting vs. Satiety) resulted in a 20.0% greater probability of switching from “fat” to “thin” (SE = 0.056, z = 3.631, p < 0.0001). Notably, figures judged as “fat” in the fasting condition were judged as “thin” in the satiety condition. Thus, we concluded that satiety relaxes criteria for judging the thinness of others’ body shapes.
Theory of Raman Scattering in One-Dimensional Quantum Spin-1/2 Antiferromagnets
Masahiro Sato,Hosho Katsura,Naoto Nagaosa
Physics , 2011, DOI: 10.1103/PhysRevLett.108.237401
Abstract: We study theoretically the Raman scattering spectra in the one-dimensional (1D) quantum spin-1/2 antiferromagnets. The analysis reveals that their low-energy dynamics is exquisitely sensitive to various perturbations to the Heisenberg chain with nearest-neighbor exchange interactions, such as magnetic anisotropy, longer-range exchange interactions, and bond dimerization. These weak interactions are mainly responsible for the Raman scattering and give rise to different types of spectra as functions of frequency, temperature, and external field. In contrast to the Raman spectra in higher dimensions in which the two-magnon process is dominant, those in 1D antiferromagnets provide much richer information on these perturbations.
Symmetry and Topology in Superconductors - Odd-frequency pairing and edge states -
Yukio Tanaka,Masatoshi Sato,Naoto Nagaosa
Physics , 2011, DOI: 10.1143/JPSJ.81.011013
Abstract: Superconductivity is a phenomenon where the macroscopic quantum coherence appears due to the pairing of electrons. This offers a fascinating arena to study the physics of broken gauge symmetry. However, the important symmetries in superconductors are not only the gauge invariance. Especially, the symmetry properties of the pairing, i.e., the parity and spin-singlet/spin-triplet, determine the physical properties of the superconducting state. Recently it has been recognized that there is the important third symmetry of the pair amplitude, i.e., even or odd parity with respect to the frequency. The conventional uniform superconducting states correspond to the even-frequency pairing, but the recent finding is that the odd-frequency pair amplitude arises in the spatially non-uniform situation quite ubiquitously. Especially, this is the case in the Andreev bound state (ABS) appearing at the surface/interface of the sample. The other important recent development is on the nontrivial topological aspects of superconductors. As the band insulators are classified by topological indices into (i) conventional insulator, (ii) quantum Hall insulator, and (iii) topological insulator, also are the gapped superconductors. The influence of the nontrivial topology of the bulk states appears as the edge or surface of the sample. In the superconductors, this leads to the formation of zero energy ABS (ZEABS). Therefore, the ABSs of the superconductors are the place where the symmetry and topology meet each other which offer the stage of rich physics. In this review, we discuss the physics of ABS from the viewpoint of the odd-frequency pairing, the topological bulk-edge correspondence, and the interplay of these two issues. It is described how the symmetry of the pairing and topological indices determines the absence/presence of the ZEABS, its energy dispersion, and properties as the Majorana fermions.
Relationship between the Influence of Others’ Opinions on Taste during Co-Eating and the Empathy of Individuals  [PDF]

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.

Pharmacology & Pharmacy (PP) , 2012, DOI: 10.4236/pp.2012.31007
Abstract: Peripheral neuropathy is a major adverse event associated with oxaliplatin-based chemotherapy and is a major dose-limiting adverse event in clinical practice. However, some patients treated with oxaliplatin may show no or minimal peripheral neuropathy. These differences are still poorly understood. The data on patients with colorectal cancer who received oxaliplatin-based regimens between January 2005 and June 2010 at South Miyagi Medical Center were retrospectively retrieved from the medical records. We selected 51 patients, and factor analysis was performed. The serum chlorine (Cl) level at baseline was significantly higher in patients with a high frequency of peripheral neuropathy (106; range 104 - 107 vs. 104; range 101 - 104 mEq/L, p = 0.02). Principal component analysis showed the variables Cl, body mass index, status of liver metastasis, and status of lymph node metastasis were related to the incidence of peripheral neuropathy. Discriminant analysis showed the model had predicted 72.5% of peripheral neuropathy. An understanding of the patient’s characteristics could be useful for preventing or predicting oxaliplatin-induced peripheral neuropathy.
Surface Roughness of SiGe/Si(110) Formed by Stress-Induced Twins and the Solution to Produce Smooth Surface  [PDF]

Journal of Materials Science and Chemical Engineering (MSCE) , 2018, DOI: 10.4236/msce.2018.61004
Abstract:
Lattice-strained Si thin films grown onto SiGe(110)/Si(110) are attracting because of their potential to realize high-speed transistors. In this study we observe surface morphology of Si/SiGe/Si(110) using scanning electron microscopy and we also observe microstructure of the identical position using cross-sectional transmission electron microscopy. These results reveal that crossing of stress-induced twins causes remarkable surface roughness. We propose using vicinal substrate to avoid this phenomenon and our successive experimental results are shown in this paper.
Ultrasound Guided Obturator Versus Sciatic Nerve Block in Addition to Continuous Femoral Nerve Block for Analgesia After Total Knee Arthroplasty
Keita Sato, Seijyu Sai, Naoto Shirai and Takehiko Adachi
Japanese Clinical Medicine , 2012, DOI: 10.4137/JCM.S7399
Abstract: Both obturator and sciatic nerve block in combination with femoral nerve block (FNB) have been suggested to be useful in relieving pain after total knee arthroplasty (TKA), compared with FNB alone. We compared their efficacy in this retrospective study. For six consecutive months, patients undergoing unilateral TKA under general anesthesia with continuous FNB plus obturator nerve block (n = 8) or continuous FNB plus sciatic nerve block (n = 8) were investigated. Knee pain was assessed using visual analogue scale (VAS) on the day of surgery and on postoperative days one to three. In addition, we also investigated intraoperative and postoperative morphine consumption. VAS scores and total morphine consumption were not different between the two groups, although patients in the FNB plus sciatic nerve block group were administered less morphine during surgery. Sciatic nerve block with continuous FNB may be superior to obturator nerve block with continuous FNB for analgesia during surgery for TKA.

World Journal of Cardiology , 2012, DOI: 10.4330/wjc.v4.i5.188
Abstract: AIM: To investigate the luminal esophageal temperature (LET) at the time of delivery of energy for pulmonary vein isolation (PVI). METHODS: This study included a total of 110 patients with atrial fibrillation who underwent their first PVI procedure in our laboratory between March 2010 and February 2011. The LET was monitored in all patients. We measured the number of times that LET reached the cut-off temperature, the time when LET reached the cut-off temperature, the maximum temperature (T max) of the LET, and the time to return to the original pre-energy delivery temperature once the delivery of energy was stopped. RESULTS: Seventy-eight patients reached the cut-off temperature. It took 6 s at the shortest time for the LET to reach the cut-off temperature, and 216.5 ± 102.9 s for the temperature to return to the level before the delivery of energy. Some patients experienced a transient drop in the LET (TDLET) just before energy delivery. Ablation at these sites always produced a rise to the LET cut-off temperature. TDLET was not observed at sites where the LET did not rise. Thus, the TDLET before the energy delivery was useful to distinguish a high risk of esophageal injury before delivery of energy. CONCLUSION: Sites with a TDLET before energy delivery should be ablated with great caution or, perhaps, not at all.
