InfIuences on the protein synthesis of rat liver by adrenal surgery
No full textThe author studied on the protein synthesis of rat liver influenced by adrenal surgery. The rat liver conditions were normal, acute medical toxicosis, treated with anticancer agents, and liver cirrhosis. On these conditions, adrenalectomy, or adreno-portal operation was performed and the nessesity of glucocorticoid and importance of albumin were clarified
Risky health behaviors and behavioral differences of the US youth: quasi-evidence with empirical study: policy implications
No full textThe focus of this paper is to examine the determinants and analyze the effects of risky health behaviors of alcohol and illicit drug use on social violence (drunken driving, riding in a car driven by a drunken driver, and not wearing seatbelts) among youth in the United States. Alcohol and illicit drug use usually lead to social violence as well as a reduction in health status and earnings. Although it is illegal to drink and drive in the U.S., forty-five percent of the traffic accidents among the age group of 14-18 are alcohol-related. Alcohol is a leading factor in deaths related to motor vehicle accidents.
This research defines use of alcohol, tobacco, cocaine, and other illicit drug use as risky health behavior. The use of some substances tend to precede and increase the risk of initiating habitual use of substances among the youth. The data used for this project is drawn from the 1992 and 2017 National Youth Risk Behavior Survey to examine the behavioral difference between two periods. The study examines the relationship between alcohol and illicit drug use and three types of violent behaviors: (1) drunken driving, (2) occupying a car driven by someone who has been drinking, and (3) not wearing seatbelts.
The results show that there is a positive relationship between the risky health behaviors of alcohol and illicit drug uses and social violence (drunken driving, riding in a car driven by a drunken driver, and not wearing seatbelts) among youth. The results suggest that binge drinking, smoking habits, as well as illicit drug use will contribute to the escalation of habitual, high-risk behaviors such as: drunken driving and not using seatbelts, among youth. The results also indicate that youth attitudes toward drunken driving will become more sensitive to multi-consumption habits as they get old. Controlling the consumption of alcohol and drug use at an early age is indeed an important factor in reducing drunken-driving behavior later. Drunken driving behavior is more likely to be a habitual behavior, and to reduce this behavior, access to alcohol and illicit drugs must be restricted among early teens.This audio recording was presented at the first annual Celebration of Undergraduate Research and Creative Activity while the author was an undergraduate student at Rutgers University-Camden
Defect (p,q) five-branes
No full textAbstractWe study a local description of composite five-branes of codimension two. The formulation is constructed by virtue of SL(2,Z)×SL(2,Z) monodromy associated with two-torus. Applying conjugate monodromy transformations to the complex structures of the two-torus, we obtain a field configuration of a defect (p,q) five-brane. This is a composite state of p defect NS5-branes and q exotic 522-branes. We also obtain a new example of hyper-Kähler geometry. This is an ALG space, a generalization of an ALF space which asymptotically has a tri-holomorphic two-torus action. This geometry appears in the conjugate configuration of a single defect KK5-brane
Self-Organized Synchronization Phenomena in Spatiotemporal Coupled Oscillator Model for Emergent Systems
No full textThe author proposes a spatiotemporal coupled Lorenz model with an excitatory-excitatory connection or an excitatory-inhibitory connection, which consists of three temporal coupling coefficients c1,2,3 and three spatial coupling coefficients d1,2,3. This model is an emergent device that has synchronized three nonlinear oscillators. In this study, the author discovers that self-organized various phase transition phenomena appear in this model in changing the values of c1,2,3 and d1,2,3 in the case of using the excitatory-inhibitory connection. Proposed model also concerns the neural population model for autonomous agent

Margin Preserved Approximate Convex Hulls for Classification
No full textThe usage of convex hulls for classification is discussed with a practical algorithm, in which a sample is classified according to the distances to convex hulls. Sometimes convex hulls of classes are too close to keep a large margin. In this paper, we discuss a way to keep a margin larger than a specified value. To do this, we introduce a concept of "expanded convex hull" and confirm its effectiveness
NHKスペシャル『原爆初動調査 隠された真実』のグラフ作成に用いた残留放射線測定データと計算手法
No full textIn the evening of August 9th. 2021, the 76th anniversary of the Nagasaki atomic bomb, a documentary TV program titled “Atomic Bomb Initial Investigation: Hidden Truth” was broadcast by NHK. In the program, dynamic graphics of residual radiation dose rate after the atomic bombing were shown both in Hiroshima and Nagasaki. Following the request from NHK directors, the author estimated about 15 mSv/h of air dose rate due to neutron activation near the Hiroshima hypocenter at one hour after the explosion, while it was about 98 mSv/h in the Nishiyama area 2.5 km east from the Nagasaki hypocenter due to local radioactive fallout, using the data of historical measurements by Japanese and US scientists after the bombings. In this note, the data and the method used to make graphics of residual radiation dose rate are explained

Construction of convex hull classifiers in high dimensions
No full textWe propose an algorithm to approximate each class region by a small number of approximated convex hulls and to use these for classification. The classifier is one of non-kernel maximum margin classifiers. It keeps the maximum margin in the original feature space, unlike support vector machines with a kernel. The construction of an exact convex hull requires an exponential time in dimension, so we find an approximate convex hull (a polyhedron) instead, which is constructed in linear time in dimension. We also propose a model selection procedure to control the number of faces of convex hulls for avoiding over-fitting, in which a fast procedure is adopted to calculate an upper-bound of the leave-one-out error. In comparison with support vector machines, the proposed approach is shown to be comparable in performance but more natural in the extension to multi-class problems
Trade Policy at the Cross-Roads
No full textIt is now widely agreed that the World Trade Organization (WTO) is in trouble, struggling to deliver the national rewards available from liberalising through multilateral negotiations. Prime Minister Howard and President Bush have committed to help restore the ability of the WTO system to deliver those rewards. This paper examines the contribution of domestic transparency procedures, introduced by and operating within participating countries, in dealing with the domestic causes of the problem facing the multilateral system. It explains the relevance of the proposal, prepared for Prime Minister Howard, in meeting the commitment he has taken. The Hong Kong Ministerial Meeting in December 2005 provides an opportunity to advance such a proposal and, in doing so, enhance our own trade performance. The author was involved, with Alf Rattigan and John Crawford, in establishing the Industries Assistance Commission and was its chairman from 1985 to 1988. He was a member of the international study group chaired by the former Director-General of the GATT, Olivier Long which drew attention during the Uruguay Round of multilateral trade negotiations (1986 1994) to the need for domestic transparency in trade policy. He co-authored a review of trade policy conduct of industrial nations, which was published by the National Centre for Development Studies in 1996. He and Professor Ross Garnaut prepared a domestic transparency proposal for Prime Minister Howard in February 2004 to provide the basis for an Australian initiative in the Doha Round. This paper explains how this proposal would contribute to restoring an effective WTO system by enabling domestic economic welfare to replace domestic political pressures as the driver of multilateral trade negotiations.World Trade Organization, trade, policy, multilateral, negotiations, Howard, Bush
