Stable Marriage Matching for Traffic-Aware Space-Air-Ground Integrated Networks: A Gale-Shapley Algorithmic Approach (2022)

In keeping with the rapid development of communication technology, a new communication structure is required in the next-generation communication system. In particular, research on using High Altitude Platform (HAP) or Unmanned Aerial Vehicle (UAV) to the existing terrestrial network is being actively conducted. In this paper, we propose the method to match HAP and UAV using the Gale-Shapley algorithm in relay communication. The numerical simulation results demonstrate that applying the Gale-Shapley algorithm(GSA) shows superior performance compared to random matching.
First‐principle investigation of strain effects on the electronic properties of germanium nanowires (2009)

Abstract Using the GGA functional in density functional theory, the effects of axial strain on the band structure and effective mass of narrow [110] and [100] germanium nanowires are investigated. It is observed that both compressive and tensile strain cause indirect‐to‐direct bandgap transitions. One percent of tensile strain can cause a 40 meV change in the bandgap of [110] nanowires. Effective masses of electrons and holes are subject to a change of 3–4 times in the strain‐induced transition point. This change translates into a density of state modulation which opens new possibilities for the construction of Ge nanowire‐based sensors. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
A simple miniature optical spectrometer with a planar waveguide grating coupler in combination with a plano-convex lens (2006)

A miniature optical spectrometer with a thin-film planar waveguide grating coupler in combination with a miniature plano-convex focusing lens has been investigated. With optical part of the spectrometer as small as 0.2 cubic cm, the spectral resolution varies from 0.3 nm to 4.6 nm within the wavelength range 488.0 nm - 632.8 nm.
A Comparative Study of Laparoscopy and Colpotomy for the Removal of Ovarian Dermoid Cysts (1996)

Laparoscope-assisted transvaginal ovarian cystectomy allows the removal of larger dermoid cysts, with less cyst spillage and savings in operative time and equipment compared with conventional laparoscopic cystectomy.
A dose‐ranging study of the pharmacokinetics of hydroxy‐chloroquine following intravenous administration to healthy volunteers. (1988)

1. The pharmacokinetics of hydroxychloroquine were studied in five healthy volunteers following an intravenous infusion of 155 mg (2.47 +/- 0.25 mg kg-1) racemic hydroxychloroquine. Four of these volunteers also received a further 310 mg (4.92 +/- 0.45 mg kg-1) infusion of hydroxychloroquine and evidence of nonlinearities in the pharmacokinetics of hydroxychloroquine were sought. 2. No nonlinear elimination or distribution processes appeared to be operating at the doses of hydroxychloroquine used in this study, supporting the hypothesis that in the therapeutic dosing range the pharmacokinetics of hydroxychloroquine are linear. 3. Half-life and mean residence time were long (around 40 days) and large volumes of distribution were calculated (5,522 l from blood, 44,257 l from plasma). Sequestration into the tissues is an important feature of the disposition of hydroxychloroquine. The persistence of hydroxychloroquine in the body is due primarily to this extensive tissue distribution, rather than to low clearance (667 ml min-1 based on plasma data, 96 ml min-1 based on blood data). 4. Plasma data were more variable than blood data. Blood to plasma concentration ratios were not constant (mean +/- s.d.: 7.2 +/- 4.2). The data indicate that it is preferable to measure whole blood concentrations of hydroxychloroquine, rather than plasma concentrations, in pharmacokinetic studies. 5. The pharmacokinetics of hydroxychloroquine are similar to those of chloroquine.
Discussion of primary drying during lyophilization. (1988)

This paper examines, by means of an ideal model, the controlling mechanisms invoiced in the primary drying of the lyophilization process. With the aid of the model, the effect of temperature and desorption energy on the fraction of water molecules on the surface of the “disorder” layer, at any one instant, that have sufficient energy to leave the surface is examined. It is shown that the effect of an increase in chamber pressure, while maintaining the shelf-surface temperature, is to cause an increase in the product temperature which results in a decrease in the unit sublimation rate. Experimental data is presented to show that a significant sublimation rate can only occur when chamber pressure falls below the initial vapor pressure of the ice. The sublimation rate is shown to be best estimated from a knowledge of the heat flux (q) and the heal of sublimation.
Spray Forming and Post Processing of Superalloy Rings (2005)

Spray forming as a technology to produce near net shape components or preforms for additional forming operations with defined microstructural properties is well known for several alloys and applications. The production of spray formed superalloy rings made of IN718 and U720 for aero engine components in order to reduce production cost is the goal of the current EU-research project. Several spray runs were carried out at University of Bremen to optimize the process parameters regarding a low porosity, low segregation and a high yield. Macro and microetchings were prepared to analyze the influence of the parameter variations on before mentioned structural properties. Several optimized rings were used to examine the influence of thermomechanical processing on porosity and microstructure of spray formed superalloy rings. Hot isostatic pressing and forging processes were performed separately as well as in combination in order to obtain the ideal post processing route, which was determined via microstructure analysis. As a result of this project, it became clear that HIPping is an integral part of the postprocessing of as-sprayed material, due to the fact that it was not possible to produce as-sprayed material without porosity. The development of micro-and macro structural properties through all these processes and their variations will be shown. Another paper presented here will focus on the final properties and applications of this material.
Spectroscopic Investigations on the Effect of Proton Bombardment of Polyimide (2005)

The effect of the radiation component of the space environment on polyimide films is reviewed. Experimental data obtained by electron spin resonance and dynamical mechanical analysis proved that the ionizing radiation generates free radicals with a long lifetime through a dominant chain scission mechanism. The radiation-induced shift of the glass transition of polyimide towards lower values confirms the decrease of the average molecular mass of the polymer during irradiation. The importance of polyimide for space exploration is critically analyzed.
Phytochemical Properties and Staining Ability of Red Onion (Allium cepa)Extract on Histological Sections (2014)

The staining ability of Allium cepa (red onion) skin extract on tissue sections was determined. The dried red onion skin was ground into small pieces and 300 g (150 g for aqueous and 150 g for ethanolic extraction) of the milled dried red onion skin was used for extraction. Dark red-pigmented granules were obtained. The aqueous and ethanolic extract of mordanted (Potassium aluminum alum and ferric chloride), non-mordanted and acidified solution prepared from the extract were used to stain tissue sections. Cytoplasm of cells and connective tissues were remarkably stained in shades of redish to yellowish brown colours. Preliminary phytochemical screening of these extracts reveals that it contained alkaloid steroid ring, saponin, Tannin, Flavonoid, Cardiac glycoside and anthraquinone. The presence of pigments, saponin, tannin, contributed to the staining ability of the extract.
Gut microflora as a target for energy and metabolic homeostasis (2007)

Gut microflora may play an even more important role in maintaining human health than previously thought. The literature provides new evidence that the increased prevalence of obesity and type 2 diabetes cannot be attributed solely to changes in the human genome, nutritional habits, or reduction of physical activity in our daily lives. One must also consider this important new environmental factor, namely gut microbiota. Scientists may take into consideration a key question: could we manipulate the microbiotic environment to treat or prevent obesity and type 2 diabetes? This opens up a new area in nutrition research.
Fatty Acid Hydroperoxide Lyase in Tomato Fruits: Cloning and Properties of a Recombinant Enzyme Expressed in<i>Escherichia coli</i> (2000)

Fatty acid hydroperoxide lyase (HPL) is a member of a novel subfamily of cytochrome P450 and catalyzes a cleavage reaction of fatty acid hydroperoxides to form short-chain aldehydes and oxo-acids. A cDNA encoding tomato fruit HPL (LeHPL) was obtained. An active LeHPL was expressed in E. coli and purified. It showed highest activity against the 13-hydroperoxide of linolenic acid, followed by that of linoleic acid. 9-Hydroperoxides were poor substrates. The absorption spectrum of the purified LeHPL in the native form was similar to that of most P450s although a CO-adduct having a lambda max at 450 nm could not be obtained. LeHPL activity is reversibly inhibited by nordihydroguaiaretic acid, while salicylic acid irreversibly inhibited it. LeHPL is kinetically inactivated by fatty acid hydroperoxides, especially 9-hydroperoxides. The inactivation is prevented by inhibitors of LeHPL. Thus, HPL catalytic activity is thought to be essential to its inactivation. During the inactivation, an abolition of the Soret band was evident, indicating that inactivation is caused mainly by degradation of the prosthetic heme in LeHPL.

Role of CD4<sup>+</sup>and CD8<sup>+</sup>T Cells in Clearance of Primary Pulmonary Infection with<i>Coxiella burnetii</i> (2010)

The mechanisms of the primary adaptive immune response to Coxiella burnetii are not well known. Following inoculation of the lungs with C. burnetii Nine Mile phase I (NMI), SCID mice developed pneumonia and splenomegaly and succumbed to infection, whereas wild-type mice cleared the infection by 24 days. SCID mice reconstituted with either CD4+ T cells or CD8+ T cells alone were able to control the infection, indicating that the presence of either type of T cells was sufficient to control infection, and B cells were not necessary for primary immunity. Similarly, wild-type mice depleted of either CD4+ T cells or CD8+ T cells controlled infections in their lungs, but these mice were highly susceptible if they were depleted of both types of T cells. However, compared to CD4+ T-cell-dependent protection, CD8+ T-cell-dependent protection resulted in less inflammation in the lungs and less growth of bacteria in the spleens.
Do Current Sports Brassiere Designs Impede Respiratory Function? (2005)

As no significant restriction to exercise performance or respiratory mechanics was found when subjects wore sports brassieres, it was concluded that active females should wear a sports brassiere during physical activity to reduce breast motion and related breast pain.
Physiologic and hypertonic saline solutions impair ciliary activity in vitro (1999)

LR is an isotonic solution that has no effect on CBF. Therefore it is probable that this solution is more appropriate than saline for nasal irrigation and nebulization or antral lavage. Moreover, the results of this study suggest that mucolytic effects induced by hyperosmolarity should be attained preferably with hypertonic saline 7% in patients with cystic fibrosis or asthma. At this concentration, the ciliostatic effect is reversible, whereas irreversible changes are to be expected at higher concentrations.

>23% High-Efficiency Tunnel Oxide Junction Bifacial Solar Cell With Electroplated Cu Gridlines (2014)

Based on the metal-insulator-semiconductor concept, Triex cell is a proprietary device structure that combines a tunnel oxide junction with doped a-Si thin-film emitter layers on n-type Czochralski silicon wafers. A simple patterning process is used along with cost-effective copper electrochemical plating to form the electrodes. This paper reports a >23% high-efficiency Triex solar cell, postoptimizing key process areas to improve passivation, junction quality, and shading effects. High open-circuit voltage (V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oc</sub> ) of 739 mV and good fill factor of 80.5% have been demonstrated on a 6-in solar cell. A champion 380-W Triex bifacial module is also validated under standard test conditions.
Proposed System Architecture to Enable Behavioral Control of an Autonomous Tractor (2013)

To allow emergent behavior from an autonomous tractor, a new sophisticated system architectureis proposed. It is fundamentally object oriented with only high-level message passing betweenthe objects that allow the overall system to be developed without the complexity becoming toogreat to manage. Each of the agents (Coordinator, Supervisor, Mode Changer, Route PlanGenerator, Detailed Route Plan Generator, Multiple Object Tracking, Object Classifier andHardware Abstraction Layer) could be implemented as separate processors or job-computers ona common bus. This paper describes the overall layout and functions of the elements within thesystem and gives examples of identified instances.
Distributed management by delegation (2002)

This paper introduces a novel approach to distributed computing based on delegation-agents, and describes its applications to decentralize network management. Delegation agents are programs that can be dispatched to remote processes, dynamically linked and executed under local or remote control. Unlike scripted agents, delegation agent programs may be written in arbitrary languages, interpreted or compiled. They can thus be more broadly applied to handle such tasks as real-time monitoring, analysis and control of network resources. Distributed management by delegation (MbD) uses this to manage remote elements and domains. MbD provides a paradigm for distributed, flexible, scalable and robust network management that overcomes the key limitations of current centralized management schemes.
Animated vectors for visualization of power system phenomena (1996)

This paper presents an exact mechanical analog for an electric power system that proves to be a powerful visualization tool for studying power systems issues such as load flow, transient stability, and the effects of FACTS devices. Techniques based on color and highlighting that make the method applicable to the visualization of large systems are introduced. The analog provides a means for demonstrating complex issues to audiences with little or no background in power systems. For the power engineer, the analog provides unique insights into the hows and whys of power system behavior. To the control center operator, an accurate model of the dynamic modes may bring about improved understanding of system behavior after contingencies and illustrate the relative merits of various dispatch options.
GENETIC VARIATION IN REACTION TO SCLEROTINIA STEM ROT IN <i>Brassica</i> SPECIES (1989)

Twenty-five cultivars and strains representing five Brassica species were tested under controlled conditions for their reaction to infection by Sclerotinia sclerotiorum, the causal agent of sclerotinia stem rot. Using the rate of stem lesion expansion as an indicator of the resistance of stem tissue to the pathogen, significant differences were present between species and among cultivars/strains within species. Although S 0 parent-S 1 progeny heritability of stem lesion expansion was low, S 0 plants of Brassica campestris and B. juncea with increased sclerotinia stem rot resistance could be selected.Key words: Brassica, Sclerotinia sclerotiorum, stem rot resistance, selection technique
Preparation and Properties of High-Chroma Pigments by Hybridization with Extender Pigments (1992)

一般に, 着色顔料と種々の顔料を混合すると, 混合比に伴い特有の色軌跡を描くことが知られている。化粧品用タール系色素のなかでも汎用される赤色201号 (R-201) と硫酸バリウムとを混合すると, 色相および明度は変化することなく彩度のみが向上した。種々の体質顔料の検討の結果, 顔料分散系の彩度は, 体質顔料と分散媒との屈折率差が小さい場合に向上することがわかった。この彩度の向上は, 赤色201号の粒子間に体質顔料粒子がスペーサーとして入り込むことにより, 光学的にその分散性を向上させるスペーサー効果によるものと考えられる。また, この効果は赤色202号 (R-202) 系においても同様に認められた。スペーサー効果を更に効率的かつ安定とするため, 着色顔料と体質顔料とをボールミル処理によって複合化することを試みた。得られた複合化顔料は, 顔料の混合系と比べても更に高彩度であり, 優れた分散性を備えていた。顔料の断面の走査電子顕微鏡観察 (SEM) 像から, 母核である体質顔料の粒子表面が, 着色顔料によって均一に被覆されているものであることがわかった。また, 本顔料は顔料の複合化比に伴い, 着色顔料の被覆膜厚が変化した。さらに, この膜厚は, 着色顔料を微粒化分散した場合の顔料粒径にほぼ対応することがわかった。
The Simple Economics of Easter Island: A Ricardo-Malthus Model of Renewable Resource Use (1997)

This paper presents a general equilibrium model of renewable resource and population dynamics related to the Lotka-Volterra predator-prey model, with man as the predator and the resource base as the prey. The authors apply the model to the rise and fall of Easter Island, showing that plausible parameter values generate a 'feast and famine' pattern of cyclical adjustment in population and resource stocks. Near-monotonic adjustment arises for higher values of a resource regeneration parameter, as might apply elsewhere in Polynesia. The authors also describe other civilizations that might have declined because of population overshooting and endogenous resource degradation. Copyright 1998 by American Economic Association.
Single-cell, locus-specific bisulfite sequencing (SLBS) for direct detection of epimutations in DNA methylation patterns (2015)

Stochastic epigenetic changes drive biological processes, such as development, aging and disease. Yet, epigenetic information is typically collected from millions of cells, thereby precluding a more precise understanding of cell-to-cell variability and the pathogenic history of epimutations. Here we present a novel procedure for directly detecting epimutations in DNA methylation patterns using single-cell, locus-specific bisulfite sequencing (SLBS). We show that within gene promoter regions of mouse hepatocytes the epimutation rate is two orders of magnitude higher than the mutation rate.
