Occurrence of Hyperon Superfluidity in Neutron Star Cores

Superfluidity of $\Lambda$ and $\Sigma^-$ admixed in neutron star (NS) cores is investigated realistically for hyperon ($Y$)-mixed NS models obtained using a $G$-matrix-based effective interaction approach. Numerical results for the equation of state (EOS) with the mixing ratios of the respective components and the hyperon energy gaps including the temperature dependence are presented. These are meant to serve as physical inputs for $Y$-cooling calculations of NSs. By paying attention to the uncertainties of the EOS and the $YY$ interactions, it is shown that both $\Lambda$ and $\Sigma^-$ are superfluid as soon as they appear although the magnitude of the critical temperature and the density region where superfluidity exists depend considerably on the $YY$ pairing potential. Considering momentum triangle condition and the occurrence of superfluidity, it is found that a so-called `` hyperon cooling\rq\rq~(neutrino-emission from direct Urca process including $Y$) combined with $Y$-superfluidity may be able to account for observations of the colder class of NSs. It is remarked that $\Lambda$-hyperons play a decisive role in the hyperon cooling scenario. Some comments are given regarding the consequences of the less attractive $\Lambda\Lambda$ interaction recently suggested by the `` NAGARA event\rq\rq~$^6_{\Lambda\Lambda}$He.Comment: 25 pages, 12figures; final version; will appear in Prog.

Circular DNA's from HeLa cell nuclei and mitochondria

An electron microscopic observation was made on the DNA's extracted from purified HeLa cell nuclei, mitochondria, and the whole cell, and fractionated by ethidium bromide-cesium chloride density gradient method or sucrose density gradient method. Nuclear DNA presents mainly long linear DNA derived from fragmented chromosomal DNA. In addition to this, the existence of small circular DNA molecules measuring 0.32 -1.78 &#956;, was confirmed. Mitochondrial DNA was mainly circular DNA, which measured 4.87 &#956; in the mean value of the contour lengths in the highest frequency group, and small circular DNA molecules, measuring 0.3-1.01 &#956; in contour length, were also found in an extremely low frequency.</p

A model-free predictive control method by ℓ1-minimization

We propose a new predictive control method utilizing a sparse solution of a minimization problem defined by both online and stored input/output data of the controlled system. The conventional predictive control methods generally require a mathematical model of the controlled system to predict an optimal future input to control the system. The mathematical model is usually obtained by applying a standard system identification method to the measured input/output data. The proposed method in this paper requires no mathematical model to predict future control input to achieve the desired output. This model-free control method, also called just-in-time predictive control, was originally proposed by Inoue and Yamamoto in 2004 and simplified by Yamamoto in 2014. In this paper, to develop another simplified method, we formulate an ℓ1-minimization problem. © 2015 IEEE.10th Asian Control Conference, ASCC 2015; Sutera Harbour ResortKota Kinabalu; Malaysia; 31 May 2015 through 3 June 2015; Category numberCFP15832-ART; Code 117644, Article number 724444

A New Model-Free Predictive Control Method Using Input and Output Data

The purpose of this paper is to present a new predictive control utilizing online data and stored data of input/output of the controlled system. The conventional predictive control methods utilize the mathematical model of the control system to predict an optimal future input to control the system. The model is usually obtained by a standard system identification method from the measured input/output data. The proposed method does not require the mathematical model to predict the optimal future control input to achieve the desired output. This control strategy, called just-in-time, was originally proposed by Inoue and Yamamoto in 2004. In this paper, we proposed a simplified version of the original just-in-time predictive control method. © (2014) Trans Tech Publications, Switzerland.研究者情報D

ショウニ ノ ショクモツ アレルギー ノ ジッタイ ト ショクセイカツ

Allergies rarely developed in Japan immediately after the Second World War, but have been remarkablely increased in the current two decades with the change of the life and dietary habits as like western. To date, it is deduced that recent progressive increase of allergic diseases in Japan may be caused by multi-factors rather than one major factor on the basis of the current life and dietary habits. The disadvantage reaction caused by taking food is called “adverse reaction to food”, which is divided into two categories ; one is food allergy caused by immunological reactions and the other is food intolerance caused by enzyme effects, pharmacological effects, or toxic properties. Food allergy causes in some persons, especially in infants, by eating food most of foods have possibility to cause allergy. In infants hen’s egg and cow’s milk are frequently identified as major food allergens. These foods are well inducible for toleration as they grow. On the contray, soba and peanuts that are known as food allergens but cause sometimes systemic anaphylaxis without toleration against them. The gold standard for preventing allergic symptoms in patients with food allergy is the elimination of the identified foods as allergens from diets. It is not only safe therapy but also prevents the development of other types of allergy

Washout control of a cyclic vehicular traffic flow

In this paper, we consider a decentralized control problem for suppressing the traffic jam in a cyclic traffic flow. In recent years, to explain the mechanism that causes the traffic jam, several experiments have been done for multiple vehicles on the circle. The traffic jam can be explained by the so-called optimal velocity model, the optimal velocity function which is a nonlinear function of the headway of the preceding vehicle and describes driver\u27s characteristics. In this paper, we apply washout control to suppress the traffic jam in a cyclic traffic flow not to disturb driver\u27s characteristics. Then, we show a method to select parameters to keep stability of the closed-loop system.We find that our proposed method for selecting parameters is better than the conservative method using the small gain theorem. In addition, we illustrate the effectiveness with several simulations. © 2011 IFAC

Driver centric decentralized controller design in traffic flow

金沢大学理工研究域電子情報学系In this paper, we consider a decentralized control problem for suppressing the traffic jam phenomenon in traffic flow. To analyze the phenomenon, we use the so-called optimal velocity model. In the model, the optimal velocity function which is a nonlinear function of the headway of the preceding vehicle describes driver\u27s characteristics. Without affecting the characteristics, all vehicles in traffic flow should be stabilized in a decentralized fashion. In this paper, we apply washout control which is a high pass filter based control method. We derive a stability condition and illustrate the effectiveness with several simulations. © 2009 SICE

Distributed synchronization algorithm for multi-agent system

This paper provides a distributed algorithm to guarantee synchronization between agents for multi-agent systems. Motivated by vertex coloring from graph theory, we explore an approach based on tentative overlay as a condition mapping from interrelation and interaction between each agent, which equipped with local sensing and wireless communication capabilities. The objective of the proposed algorithms is to achieve synchronization, that is, making the most of cooperation of the agents in the multi-agent systems with network\u27s connectivity, while other than nearest neighbor information, our approach assumes no knowledge of global network topology. We provide analysis and design results for multi-agent networks in arbitrary dimensions topology. The novel correctness poof relies on proximity graphs and their properties. In addition, simulations are provided that demonstrate the effectiveness of our theoretical results, for which we show a distributed dynamic programming of multi-agent system. © 2011 SICE
