Analysis of the Interaction Torque on the Arm Based on Via-Point Movement
To produce a desired movement, the human motor control system must regular the interaction torque generated owing to the multi-joint structure of the body. In this study, the trajectories of human movements were evaluated considering the interaction torque generated through the elbow and shoulder joints. Measurement experiments were conducted, in which the participants performed movements corresponding to a three-point task, and the results indicated that the interaction torque is correlated with certain characteristics of the trajectories of the arm movements. Moreover, the contribution of the interaction torque in realizing the task differs in the cases of dominant and non-dominant hands. In addition, through a simulation, the interaction torque of simulated trajectories was modulated to examine the corresponding effect on the arm movements. For a point-to-point movement, certain characteristics of the actual movements were reproduced in the simulated trajectories. However, for a three-point movement, the characteristics of the simulated trajectories were only partially similar to those of the measured trajectories. The findings indicate that the interaction torque notably influences the motor control, and the tuning of the interaction torque is more complex than the other criteria of motor control
Domain-Specific Web Search with Keyword Spices
Domain-specific web search engines are effective tools for reducing the difficulty in acquiring information from the web. Existing methods for building domain-specific web search engines require human expertise or specific facilities. However, we can build a domain-specific search engine simply by adding domain specific keywords called "keyword spices" to the user's input query and forwarding it to a generalpurpose web search engine. Keyword spices can be effectively discovered from web documents using machine learning technologies. This paper will describe domain-specific web search engines that use keyword spices for locating cooking recipes, restaurants, and used cars. To fully automate the construction of domain-specific search engines, we also present trials of using web pages in an existing web directory as training examples
Global stability of day-to-day dynamics for schedule-based Markovian transit assignment with boarding queues
Schedule-based transit assignment describes congestion in public transport
services by modeling the interactions of passenger behavior in a time-space
network built directly on a transit schedule. This study investigates the
theoretical properties of scheduled-based Markovian transit assignment with
boarding queues. When queues exist at a station, passenger boarding flows are
loaded according to the residual vehicle capacity, which depends on the flows
of passengers already on board with priority. An equilibrium problem is
formulated under this nonseparable link cost structure as well as explicit
capacity constraints. The network generalized extreme value (NGEV) model, a
general class of additive random utility models with closed-form expression, is
used to describe the path choice behavior of passengers. A set of formulations
for the equilibrium problem is presented, including variational inequality and
fixed-point problems, from which the day-to-day dynamics of passenger flows and
costs are derived. It is shown that Lyapunov functions associated with the
dynamics can be obtained and guarantee the desirable solution properties of
existence, uniqueness, and global stability of the equilibria. In terms of
dealing with stochastic equilibrium with explicit capacity constraints and
non-separable link cost functions, the present theoretical analysis is a
generalization of the existing day-to-day dynamics in the context of general
traffic assignment.Comment: 26 pages, 3 figure

Beneficial Effect of Food Substitute Containing L-Arginine, ω-3 Poly Unsaturated Fatty Acid, and Ribonucleic Acid in Preventing or Improving Metabolic Syndrome: A Study in 15 Overweight Patients and a Study of Fatty Acid Metabolism in Animals
This study was conducted to investigate whether or not a food substitute (Dr. BAANs®) containing three bioactive components L-arginine, ω-3 polyunsaturated fatty acid, and ribonucleic acid, supplied orally to 15 overweight patients, may have efficacy to prevent or improve the metabolic syndrome of these patients. To provide supporting data for this clinical study, the in vivo fatty acid metabolism of obese mice was analyzed using 125I labeled 15-(p-iodophenyl)-9-methylpentadecanoic acid (9MPA) in the tissues’ lipid pool. After 3 months of intervention, the results showed that there were improvements observed in liver functions, lipid profiles and metabolic syndrome marker. Significant differences were also found in the values of blood pressure, body weight, percentage of body fat, and body mass index. In the animal study, the tissue uptake of 125I-9MPA at 10 min after injection was higher in obese mice than in the control mice and the treatment with Dr. BAANs® in obese mice decreased the uptake significantly. The final product metabolite of p-iodophenylacetic acid in obese mice was increased significantly by the treatment. In conclusion, this food substitute may have a beneficial effect for the prevention or improvement of metabolic syndrome

Anesthetic Care of a Patient with AFE
Two types of amniotic fluid embolism (AFE) have been described : cardiopulmonary collapse type and disseminated intravascular coagulation (DIC) type, with the latter proposed as uterine type. This report describes a healthy 28-year-old woman who developed AFE during a cesarean section. Because of a previous cesarean section, the patient underwent an elective cesarean section, under combined spinal-epidural anesthesia, at 38 weeks of pregnancy. She began coughing 5 minutes after delivery of the fetus, subsequently becoming unconscious and developing glossoptosis and bradycardia. Her blood pressure decreased to 76/43 mmHg, and AFE was suspected. Her uterus was atonic, and she experienced persistent noncoagulant bleeding, with a final blood loss of 6300 ml. Considerable blood transfusion was required. The patient survived, and she and her baby were discharged without any sequelae on the eighth postoperative day. This patient met the Japanese criteria for clinical AFE, with an obstetrical DIC score of 21 meeting the criteria for obstetrical DIC. Early diagnosis and treatment likely resulted in patient survival
