Origin of supercharging in electrospray ionization of noncovalent complexes from aqueous solution (2009)

The use of m-nitrobenzyl alcohol (m-NBA) to enhance charging of noncovalent complexes formed by electrospray ionization from aqueous solutions was investigated. Addition of up to 1% m-NBA can result in a significant increase in the average charging of complexes, ranging from approximately 13% for the homo-heptamer of NtrC4-RC (317 kDa; maximum charge state increases from 42+ to 44+) to approximately 49% for myoglobin (17.6 kDa; maximum charge state increases from 9+ to 16+). Charge state distributions of larger complexes obtained from heated solutions to which no m-NBA was added are remarkably similar to those containing small amounts of m-NBA. Dissociation of the complexes through identical channels both upon addition of higher concentrations of m-NBA and heating is observed. These results indicate that the enhanced charging upon addition of m-NBA to aqueous electrospray solutions is a result of droplet heating owing to the high boiling point of m-NBA, which results in a change in the higher-order structure and/or dissociation of the complexes. For monomeric proteins and small complexes, the enhancement of charging is lower for heated aqueous solutions than from solutions with m-NBA because rapid folding of proteins from heated solutions that do not contain m-NBA can occur after the electrospray droplet is formed and is evaporatively cooled.

Analysis of Trapped Magnetic Field During Magnetization Process by SPA Method of Bulk Superconductor (2014)

Dispersion quality of metal particle inks measured by a magnetic probing technique and its relation to tape quality (1992)

The dispersion quality of magnetic inks made from iron-based metal particle has been investigated using a magnetic probing technique known as dispersion by magnetic measurement (DIMAG). A comparison of the DC magnetic field (DCON) values measured at different binder levels to the tape characteristics shows that dispersions with large negative DCON signals result in good-quality tapes. The DIMAG technique is useful in a qualitative characterization of the dispersion quality of metal particle inks prepared at different wetting binder concentrations. The sensitivity of the DIMAG signal to the binder level and the correlation between the DIMAG signal and tape quality imply that the DIMAG technique has the potential of providing information on optimum ink formulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Reading Ability After Recovering From Amblyopia in Children With Hyperopia (2012)

目的：遠視を有する児童における読書能力を調査し、年齢変化と弱視が治癒した後の経過期間が、読書能力に及ぼす影響について検討した。対象及び方法：対象は、西葛西井上眼科こどもクリニックを受診した6歳～12歳の両眼の屈折が遠視で、現在の矯正視力、両眼視機能が良好な小学生110例で、不同視がない症例とした。方法は、ひらがな単語で構成された読書チャートMNREAD-Jkを用い、日常視の状態を調査するため両眼開放、屈折異常矯正下にて測定した。読書能力評価は、最大読書速度、臨界文字サイズ、読書視力の3つのパラメーターで行い、年齢と弱視治癒後経過期間ごとに検討した。結果：年齢別検討では、最大読書速度に年齢による主効果がみられたが、臨界文字サイズ、読書視力においてみられなかった。弱視治癒後経過期間の検討における最大読書速度は、経過期間が長くなるに従って速度も上昇した。さらに、年齢と弱視治癒後経過期間を要因に重回帰分析を行ったところ、どちらも貢献しているが、年齢の方がその比重は大きかった。結論：遠視児童の読書能力において、年齢に加え弱視が治癒と診断されてからの経過期間の影響も受けることから、弱視は、早期発見・早期治療が重要であることが再認識された。
ASSESSMENT OF THE SST AND OMEGA-BASED REYNOLDS STRESS MODELS FOR THE PREDICTION OF FLOW AND HEAT TRANSFER IN A SQUARE-SECTION U-BEND (2008)

The simulation of flow and heat transfer at a U-bend of a square-section duct is used to test the performance of two turbulence models: the Shear Stress Transport (SST) model and an omega-based Reynolds stress model. In both cases a sufficiently fine computational mesh is used such that the models are integrated to the wall and no wall function treatment is used. All simulations are performed using ANSYS CFX. The models are initially tested for fully-developed flow and heat transfer in straight ducts and are shown to agree well with accepted correlation data. Comparisons with literature data are made for both the flow field and the wall heat transfer coefficient. Particular attention is given to an assessment of the ability of the models to predict the secondary flows and their impact on subsequent heat transfer predictions. The results show only minor differences between the predictions of the SST and the omega-based Reynolds stress model.
EFFECT OF INOSITOL AND OCTADECYL ALCOHOL FEEDING ON LIPOPROTEINS IN CHOLESTEROL FED RABBITS (1952)

A controversy exists as to the effect of inositol and other lipotropic agents on serum cholesterol levels and atherosclerosis in humans and animals. There is no general agreement that these agents lower serum cholesterol levels or exert an inhibitory effect on the development of atherosclerosis.,
Facial expressional adaptation aftereffects contingent on racial categories (2010)

Face identity and facial expression are believed to be represented by separate neural mechanisms in the human brain. Both face identity and facial expression are adaptable and perceptual aftereffects can be observed in each. Further, expression aftereffects can be generated with faces of different individuals, consistent with an expression representation independent of identity representation. However, given the well known “other-race” effect in face perception, it remains possible that faces from different races are encoded by distinct neural mechanisms or different neuronal subpopulations. Consequently, the question arises on whether there is a single expression analysis system across faces from different race categories. We investigated this issue by testing whether or not a race-contingent expressional aftereffect could be observed, despite evidence that expression aftereffects are insensitive to identity within the same race. Participants adapted to alternating faces of two different races (Caucasian (C) and African American (AA)). During adaptation, faces from the two races were consistently rendered in two opposing expressions (e.g., C-happy and AA-sad or the other way around). Following this combined adaptation, briefly presented faces with neutral expression were perceived as slightly sad or happy, depending on the racial category of the test face and the race-expression pairings during adaptation. The results show that facial expression adaptation could be made contingent on the racial identity of the faces. These results suggest that facial expression analysis is not completely independent of the face identities. At the neuronal level, the observation of a race-contingent expression aftereffect implies the existence of neurons with joint tuning sensitivity to expression and racial category of the face.
Rat Liver Peroxisomes, II. Stimulation of Peroxisomal Fatty-Acid β-Oxidation by Thyroid Hormones (1983)

From liver homogenates of control and thyroxine-treated rats the light mitochondrial fractions were prepared by differential centrifugation. Mitochondria and peroxisomes of these fractions were further separated by isopycnic sucrose density gradient centrifugation. Analysis of the activities of the peroxisomal marker enzymes catalase and urate oxidase throughout the gradient exhibited completely corresponding distributions with that of peroxisomal palmitoyl-CoA oxidation. Thyroxine treatment did not change the proportion of mitochondria and peroxisomes present in the differential fractions of the homogenate. Consequently, the activities of peroxisomal beta-oxidation in the light mitochondrial fractions of control and thyroxine-treated animals were directly comparable with each other. A 2.5-fold increase in peroxisomal palmitoyl-CoA oxidation raising the activity from 0.089 to 0.220 U/g as estimated in the light mitochondrial fractions was found following treatment of male rats with daily doses of 25 micrograms L-thyroxine (s.c.) over a period of 10 days. Total hepatic peroxisomal fatty-acyl-CoA oxidation was calculated based on estimations in the light mitochondrial fractions. The difficulties encountered herein are discussed. The present result replenishes the broad spectrum of cellular effects exerted by thyroid hormones and indicates that both the mitochondrial and the peroxisomal system contribute to the well known hormone effects such as increase in fatty-acid oxidation, O2 consumption and heat production.
Distribution of Ia‐Antigen‐like Molecules on Non‐lymphoid Tissues (1979)

Ia-antigen-like molecules are expressed on cells within several different non-lymphoid tissues of the guinea-pig. In indirect immunofluorescence analyses anti-Ia-antigen antibodies stained epithelial cells lining the intestinal tract, the bile ducts, the respiratory tract and the urinary tract. The rabbit antibodies against Ia antigens also stained the cells of the parotid and the submandibular glands. Evidence was also obtained suggesting that the reticuloepithelial cells of the thymus, like the Kupffer cells of the liver, express Ia-antigen-like molecules. In several cases indirect immunoprecipitation analyses and SDS-polyacrylamide gel electrophoresis confirmed the immunofluorescence studies inasmuch as Ia-antigen-like subunits with apparent molecular weights of 26,000 and 34,000 could be isolated from the non-lymphoid organs.
Polygon Containment and Translational Min-Hausdorff-Distance between Segment Sets are 3SUM-Hard (2025)

The 3SUM problem represents a class of problems conjectured to require $Ω(n^2)$ time to solve, where $n$ is the size of the input. Given two polygons $P$ and $Q$ in the plane, we show that some variants of the decision problem, whether there exists a transformation of $P$ that makes it contained in $Q$, are 3SUM-Hard. In the first variant $P$ and $Q$ are any simple polygons and the allowed transformations are translations only; in the second and third variants both polygons are convex and we allow either rotations only or any rigid motion. We also show that finding the translation in the plane that minimizes the Hausdorff distance between two segment sets is 3SUM-Hard.
Properties of Ti-Al-Si-N Nano-composite Films Prepared by Reactive Sputtering (2004)

The influence of Si addition on the microstructure, mechanical properties and oxidation resistance of Ti-Al-Si-N was investigated using XRD, XPS, SEM and ultra-microindentaion. The composite targets consisting of a Ti50Al50 plate and Si chips were sputtered in a mixture of argon and nitrogen. Ti-Al-Si-N films were prepared in an r.f. sputtering apparatus of the Facing Target-type Sputtering. During the deposition, the substrate was heated from room temperature up to -573 K without substrate bias application. The total results of XRD, XPS and SEM revealed that the Ti-Al-Si-N films have a nano-composite structure consisting of nanocrystalline Ti-Al-N and an amorphous phase containing Si3N4. The highest hardness of 38 GPa was obtained for films with 3.5%Si. The films were subjected to an oxidation test, where they were exposed to a temperature in the range of 873 K to 1193 K for 1 ks. The hardness of Ti-Al-Si-N films hardly decreased after oxidation test up to 973 K, whereas the hardness of Ti-Al-N films decreased 7% at 973 K. Only a small TiO2 peak was observed for the Ti-Al-Si-N films oxidized at 973 K, whereas many TiO2 peaks were observed in the Ti-Al-N film. SEM & EDS observation revealed that the inside of the Ti-Al-Si-N film was not oxidized even after oxidation test at 1193 K. These improvements of Ti-Al-Si-N films could be attributed to the formation of nano-composite structure.

Process details as well as initial electrical characterization results on fully functional gate Gd2O3 dielectric MOSFETs with equivalent oxide thickness (EOT) down to 1nm are discussed.
On the Impact of Subproblem Orderings on Anytime AND/OR Best-First Search for Lower Bounds (2016)

Best-first search can be regarded as anytime scheme for producing lower bounds on the optimal solution, a characteristic that is mostly overlooked. We explore this topic in the context of AND/OR best-first search, guided by the MBE heuristic, when solving graphical models. In that context, the impact of the secondary heuristic for subproblem ordering may be significant, especially in the anytime context. Indeed, our paper illustrates this, showing that the new concept of bucket errors can advise in providing effective subproblem orderings in AND/OR search.
Fidelity of Task Structure as a Guiding Principle in the Development of Skill Trainers Based upon Complex Computer Games (1988)

Fidelity of task structure is proposed to replace physical fidelity, as a cost effective guiding principle in the development of trainers for complex tasks. The paper describes a research project in which a complex computer game was designed to mimic the requirements of flight skill. It was then employed as part trainer within an actual flight training program. The game was mainly directed to teach subjects strategies of attention control and efficient allocation of processing resources. It was found to improve trainees performance in flight. The paper discusses the theoretical roots of the proposed approach and some results of its application in an actual training environment.
Effect of parent artery expansion by stent placement in cerebral aneurysms (2014)

These data suggest that parent artery expansion and its effect should be measured and included in the total decrease in blood flow. Parent artery expansion may induce intimal hyperplasia, thus increasing the thickness of the aneurysm wall.

Molecular dissection of protein–protein interactions between integrin α5β1 and the <i>Helicobacter pylori</i> Cag type <scp>IV</scp> secretion system (2017)

The more severe strains of the bacterial human pathogen Helicobacter pylori produce a type IV secretion system (cagT4SS) to inject the oncoprotein cytotoxin-associated gene A (CagA) into gastric cells. This syringe-like molecular apparatus is prolonged by an external pilus that exploits integrins as receptors to mediate the injection of CagA. The molecular determinants of the interaction of the cagT4SS pilus with the integrin ectodomain are still poorly understood. In this study, we have used surface plasmon resonance (SPR) to generate a comprehensive analysis of the protein-protein interactions between purified CagA, CagL, CagI, CagY repeat domain II (CagY<sup>RRII</sup> ), CagY C-terminal domain (CagY<sup>B</sup><sup>10</sup> ) and integrin α5β1 ectodomain (α5β1<sup>E</sup> ) or headpiece domain (α5β1<sup>HP</sup> ). We found that CagI, CagA, CagL and CagY<sup>B</sup><sup>10</sup> but not CagY<sup>RRII</sup> were able to interact with α5β1<sup>E</sup> with affinities similar to the one observed for α5β1<sup>E</sup> interaction with its physiological ligand fibronectin. We further showed that integrin activation and its associated conformational change increased CagA, CagL and CagY<sup>B</sup><sup>10</sup> affinities for the receptor. Furthermore, CagI did not interact with integrin unless the receptor was in open conformation. CagI, CagA but not CagL and CagY<sup>B</sup><sup>10</sup> interacted with the α5β1<sup>HP</sup> . Our SPR study also revealed novel interactions between CagA and CagL, CagA and CagY<sup>B</sup><sup>10</sup> , and CagA and CagI. Altogether, our data map the network of interactions between host-cell α5β1 integrin and the cagT4SS proteins and suggest that activation of the receptor promotes interactions with the secretion apparatus and possibly CagA injection.
