Overview and the Future of Phase-Change Optical Disk Technology (2000)

Phase-change optical disk technology in the early days dealt with three issues: cyclability, erase characteristics and sensitivity. These were resolved by materials development, and disk layer structure technologies. This paper shows the high (carrier to noise ratio) C / N recording characteristics of a multi-level phase-change optical disk. Multi-level mark radial width modulation (MRWM) recording experiments have demonstrated 4-level (level 0, level 1, level 2 and level 3) recording capability. Even level 1 marks with a radial width of 200 nm have a high C / N ratio of more than 50 dB. The laser pulse width and laser power assigned MRWM, M -level recording is expected the potential for marks storing density proportionally to log 2 M . This technology offers the feature of enhanced density and compatibility with a digital versatile disk (DVD) pick-up.
P3A-2 Analytical Modeling of Plane Shear Wave Diffraction By a Radially Layered Cylinder For Dynamic Vascular Elastography (2007)

In the context of dynamic vascular elastography (DVE), this paper proposes an analytical model to simulate the diffraction of harmonic and transient plane shear waves by radially layered soft cylinders. The model is discussed and validated in vitro on mono and bi-layered coagulated blood inclusions buried within gelatin phantoms.
Association of cytotoxic T lymphocyte (CTL) escape mutations with persistent hepatitis C virus (HCV) infection. (1995)

Mechanisms by which HCV evades the cellular immune response in persistently infected humans and chimpanzees are poorly defined, but could involve mutations in epitopes recognized by class I MHC restricted CTLs. To investigate this possibility, we identified an epitope in the NS3 protein of HCV that was recognized by intrahepatic CTLs from a chimpanzee that developed persistent HCV infection after experimental challenge with the virus. Fine mapping studies with truncated synthetic peptides revealed that the epitope was 9 amino acids in length, encompassing residues 1445 to 1454 (GDFDSVIDC) of NS3. This sequence was completely conserved in all full-length NS3 genomes described to date. In view of the fact that the major genotypes of HCV may differ by up to -30% in overall amino acid homology, it appears in contrast that this epitope is highly conserved. The role of CTL escape mutations in HCV persistence was assessed in the virus inoculum used to infect this chimpanzee and in post-inoculation plasma samples. Sequencing of 6-10 M13 clones containing a 232-nucleotide fragment amplified with NS3-specific primers revealed that the epitope in the challenge inoculum and a post-inoculum plasma sample obtained at week 4 were identical to the published sequence of HCV-I. In contrast, all molecular clones sequenced from week 16, 25 and 28 plasma samples contained a single Asp--> Glu (D-->E) amino acid substitution at residue 1449. Significantly, four independently derived CTL clones established from the liver of this chimpanzee at various times up to two years after infection recognized target cells pulsed with a nonameric peptide representing the wild-type HCV-I sequence, but not those pulsed with a peptide containing the D-->E mutation. These data suggest that CTL escape mutations may play a role in viral persistence.
Nanomaterials for Regenerative Medicine (2010)

The application of nanotechnology has opened a new realm of advancement in the field of regenerative medicine and has provided hope for the culmination of long-felt needs by the development of an ideal means to control the biochemical and mechanical microenvironment for successful cell delivery and tissue regeneration. Both top-down and bottom-up approaches have been widely used in the advancement of this field, be it by improvement in scaffolds for cell growth, development of new and efficient delivery devices, cellular modification and tracking applications or by development of nanodevices such as biosensors. The current review elaborates the various nanomaterials used in regenerative medicine with a special focus on the development of this field during the last 5 years and the recent advances in their aforementioned applications. Furthermore, the key issues and challenges in using nanotechnology-based approaches are highlighted with an outlook on the likely future of nano-assisted regenerative medicine.
Scrub Cleaning with PVA Brushes (2018)

PVA brushes are widely used for cleaning semiconductor device surfaces. PVA brushes are a soft porous polymer which can be absorb much amount of water. In this review, we briefly introduce the proposed cleaning mechanism. Then some results of frictional analysis of PVA brushes are described. In the frictional analysis, viscoelastic behavior of the brush, surface wettability of a plate, and brush deformation during scrubbing were important. In addition, we introduce a visualization result of real contact area between PVA brush and contact surface.
Cellular responses to animal dander allergens are mediated by interactions between Allergen, Lipid and Toll-Like Receptors (2012)

Allergic responses can be triggered by a range of different proteins. The structure of many protein allergens is known, but there are no common features that explain why these should be allergens and how they are recognized by the host. Many allergens have the capacity to bind lipids. Recently the house dust mite protein Der p2 was shown to activate TLR4, by mimicking MD2, but it also sensitises the responses of TLR4 to its main ligand lipopolysaccharide (LPS). The dander protein Fel d1 is highly abundant indoors and is one of the commonest causes of cat allergy in people. Structurally it has an alpha helical structure whereas Der p2 has an anti-parallel beta-2-sheet conformation. Like Der p2, Fel d 1 has a lipid binding cavity, but is structurally unrelated to MD2. As yet there are no data describing how Fel d1, or other dander proteins, are recognized by the host.
Implementation of a frequency-agile, high power backward wave oscillator (2002)

Work at the University of New Mexico (UNM) has demonstrated how finite length effects in a high power vacuum backward wave oscillator (BWO) can be exploited to achieve frequency agility for constant beam and magnetic field parameters. This enhanced bandwidth is obtained through the axial displacement of the slow wave structure with respect to the cutoff neck "inlet" to the electrodynamic system. This paper describes progress on the implementation of this automatic displacement to facilitate the incorporation of a robust controller, as proposed by Abdallah, et al. (1996). The purpose of this controller is to demonstrate a "smart tube" where a variety of objectives, such as (i) maximizing the frequency bandwidth for a given constant power output, (ii) maximizing the radiated peak power at a given frequency, or (iii) maximizing the beam-to-microwave power conversion efficiency, can be achieved automatically.
“Keep it simple, scholar”: an experimental analysis of few-parameter segmentation networks for retinal vessels in fundus imaging (2021)

It is counter-intuitive that the U-Net produces reasonably good segmentation predictions until reaching the mentioned limits. Our work has two main contributions. On the one hand, the importance of different elements of the U-Net is evaluated, and the minimal U-Net which is capable of the task is presented. On the other hand, our work demonstrates that retinal vessel segmentation can be tackled by surprisingly simple configurations of U-Net reaching almost state-of-the-art performance. We also show that the simple configurations have better generalization ability than state-of-the-art models with high model complexity. These observations seem to be in contradiction to the current trend of continued increase in model complexity and capacity for the task under consideration.
Bioelectric Properties of Chloride Channels in Human, Pig, Ferret, and Mouse Airway Epithelia (2006)

The development of effective therapies for cystic fibrosis (CF) requires animal models that can appropriately reproduce the human disease phenotype. CF mouse models have demonstrated cAMP-inducible, non-CF transmembrane conductance regulator (non-CFTR) chloride transport in conducting airway epithelia, and this property is thought to be responsible for the lack of a spontaneous CF-like phenotype in the lung. Thus, an understanding of species diversity in airway epithelial electrolyte transport and CFTR function is critical to developing better models for CF. Two species currently being used in attempts to develop better animal models of CF include the pig and ferret. In the study reported here, we sought to comparatively characterize the bioelectric properties of in vitro polarized airway epithelia--from human, mouse, pig and ferret--grown at the air-liquid interface (ALI). Bioelectric properties analyzed include amiloride-sensitive Na(+) transport, 4,4'-diisothiocyanato-stilbene-2,2'-disulfonic acid (DIDS)-sensitive Cl(-) transport, and cAMP-sensitive Cl(-) transport. In addition, as an index for CFTR functional conservation, we evaluated the ability of four CFTR inhibitors, including glibenclamide, 5-nitro-2-(3-phenylpropyl-amino)-benzoic acid, CFTR (inh)-172, and CFTR(inh)-GlyH101, to block cAMP-mediated Cl(-) transport. Compared with human epithelia, pig epithelia demonstrated enhanced amiloride-sensitive Na(+) transport. In contrast, ferret epithelia exhibited significantly reduced DIDS-sensitive Cl(-) transport. Interestingly, although the four CFTR inhibitors effectively blocked cAMP-mediated Cl(-) secretion in human airway epithelia, each species tested demonstrated unique differences in its responsiveness to these inhibitors. These findings suggest the existence of substantial species-specific differences at the level of the biology of airway epithelial electrolyte transport, and potentially also in terms of CFTR structure/function.
Finite-Size Scaling and Lack of Self-Averaging in Critical Disordered Systems (1998)

We simulated site dilute Ising models in $d\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}3$ dimensions for several lattice sizes $L$. For each $L$ singular thermodynamic quantities $X$ were measured at criticality and their distributions $P(X)$ were determined for ensembles of several thousand random samples. For $L\ensuremath{\rightarrow}\ensuremath{\infty}$ the relative width of $P(X)$ tends to a universal constant: there is no self-averaging. The width of the distribution of the sample $(i)$ dependent pseudocritical temperatures ${T}_{c}(i,L)$ scales as $\ensuremath{\delta}{T}_{c}(L)\ensuremath{\sim}{L}^{\ensuremath{-}1/\ensuremath{\nu}}$ and not as $\mathrm{\ensuremath{\sim}}{L}^{\ensuremath{-}d/2}$. The sample dependence of ${X}_{i}(T,L)$ enters dominantly, but not exclusively, via ${T}_{c}(i,L)$.
Submicrometer optical tomography by multiple-wavelength digital holographic microscopy (2006)

We present a method for submicrometer tomographic imaging using multiple wavelengths in digital holographic microscopy. This method is based on the recording, at different wavelengths equally separated in the k domain, in off-axis geometry, of the interference between a reference wave and an object wave reflected by a microscopic specimen and magnified by a microscope objective. A CCD camera records the holograms consecutively, which are then numerically reconstructed following the convolution formulation to obtain each corresponding complex object wavefront. Their relative phases are adjusted to be equal in a given plane of interest and the resulting complex wavefronts are summed. The result of this operation is a constructive addition of complex waves in the selected plane and destructive addition in the others. Tomography is thus obtained by the attenuation of the amplitude out of the plane of interest. Numerical variation of the plane of interest enables one to scan the object in depth. For the presented simulations and experiments, 20 wavelengths are used in the 480-700 nm range. The result is a sectioning of the object in slices 725 nm thick.
Line-of-Sight Probability in Cluttered Urban Microcells: Analyses Using Poisson Point Process and Point Cloud (2021)

Line-of-sight (LOS) probability is a key component of system-level simulations that are required for creating new standards and recommendations for wireless systems. In particular, for millimeter-wave systems, an unobstructed view between the base station at an elevation and a user at ground level is important to ensure high-throughput service. While statistical models for LOS blockage by buildings exist, such models for blockage by multiple small objects, such as trees and street signs, are currently lacking. In this work, we present a Poisson point process-based analytic solution in a form of an algorithm for evaluating LOS probability in the presence of any combination of arbitrarily shaped shadowing objects, taking into account carrier frequency. The algorithm is validated against the LOS probability obtained from ray tracing in a realistic urban microcell scenario.

The results indicate that impaired insulinotropic response to GIP and GLP-1 under diabetic milieu involves mechanisms beyond simple expression of respective receptors.

Rehabilitating the ColorChecker Dataset for Illuminant Estimation (2018)

In a previous work, it was shown that there is a curious problem with the benchmark ColorChecker dataset for illuminant estimation. To wit, this dataset has at least 3 different sets of ground-truths. Typically, for a single algorithm a single ground-truth is used. But then different algorithms, whose performance is measured with respect to different ground-truths, are compared against each other and then ranked. This makes no sense. We show in this paper that there are also errors in how each ground-truth set was calculated. As a result, all performance rankings based on the ColorChecker dataset &#x2013; and there are scores of these &#x2013; are inaccurate. In this paper, we re-generate a new 'recommended' ground-truth set based on the calculation methodology described by Shi and Funt. We then review the performance evaluation of a range of illuminant estimation algorithms. Compared with the legacy ground-truths, we find that the difference in how algorithms perform can be large, with many local rankings of algorithms being reversed. Finally, we draw the readers attention to our new 'open' data repository which, we hope, will allow the ColorChecker set to be rehabilitated and once again become a useful benchmark for illuminant estimation algorithms.
Pays émergents : l’émergence de la recherche et de la coopération (2011)

La mondialisation a fait entrer les grands pays émergents – au premier rang desquels on trouve la Chine et l’Inde, soit plus de 2 milliards d’habitants – dans un processus de développement économique, technologique et social sans précédent, et elle a bouleversé les équilibres et les rapports de force anciens. Il faut s’en réjouir car cela se traduit par un recul progressif de la misère dans certains de ces pays, même si le mouvement est encore très hétérogène et inégalitaire, dans un monde où...
WebRTC-Based Remote Collaborative Learning Platform (2015)

스마트 디바이스의 보급과 더불어 스마트 TV, 웹 기반 IPTV등의 확산으로 사용자 측의 방송 콘텐츠 재생 단말의 급속한 변화가 일어나고 있다. 이러한 환경 변화를 통해 방송 콘텐츠들은 다양한 웹 서비스들이 결합된 응용 서비스들이 가능해졌으며 방송 환경에서의 웹 콘텐츠의 수용을 더욱 촉진하고 있다. 이러한 변화와 함께, 교육 콘텐츠의 경우 교수자의 강의를 일방적으로 전달하던 방송 형태에서 점차 웹을 응용한 온라인 교육 환경으로 발전함에 따라 점점 교수자와 학습자간의 상호작용에 대한 요구가 증가하고 있다. 본 논문에서는 웹 기술과 방송이 결합된 환경에서 양방향 교육 환경을 지원하기 위해, WebRTC (Web Real-Time Communication) 기반 원격 협업 학습 플랫폼을 제안한다. 변화된 환경에서의 원격 협업 교육 서비스 시나리오 도출을 통해 요구사항을 정의하고, 이를 지원하기 위한 웹 기반 원격 협업 콘텐츠 객체 공유 기술과 협업 스트리밍 기술을 제시한다. 특히 WebRTC를 기반으로 한 효율적인 사용자 세션 제어, 연동 및 관리를 위한 협업 교육 플랫폼 구조 제안 및 구현을 통해 실제 교육 환경에서의 적용 및 검증하고, 본 기술의 가능성을 확인하였다. Recently, as the number of smart devices (such as smart TV or Web based IPTV) increases, the way of digital broadcast contents is changed. This change leads that conventional broadcast media accepts Web platform and its services to provide more quality contents. Based on this change, in education field, education broadcasting also follows the trend. The traditional education broadcasting platforms, which just delivered the lecture in one-way, are utilized the Web technology to make interaction between teacher and student. Current education platforms, however, are insufficient to satisfy users' demands for two-way interactions. This paper proposes a new remote collaborative learning platform which able to provide high interactivity among users. Based on new functional requirements from original use case, the platform provides collaborative contents sharing and collaborative video streaming techniques by utilizing WebRTC (Web Real-Time Communication) technology. The implementation demonstrates the operability of proposed system.
3D finite element analysis of indentation recovery due to the shape memory effect (2010)

The potential use of Shape Memory Alloys (SMAs) as micro-actuators promotes study of the behaviors of these materials at small length scales. The recovery of micro-indentations due to the shape memory effect has recently become an area of particular interest. Experimental observation indicates promising microactuation ability in SMAs subject to indentation. In order to better understand the mechanisms underlying this phenomenon, 3- D Finite Element Analysis incorporating a new SMA transformation-plastic yield constitutive model is used to simulate a unique experimental indentation procedure. This process involves the indentation of an SMA material and the planarization of the material surface to remove all visible traces of the indent region; upon subsequent heating, a protrusion (exdent) is created in the indented zone. Key results of an analysis that simulates this experimental procedure are discussed, along with possibilities for future work.
Electrical tree formation as a measure of degradation resistance in polymeric materials for HVDC applications (2013)

In the framework of elaborating a methodology for testing the resistance to electrical treeing of polyethylene (PE) for HVDC applications, electrical tree inception tests were performed before and after a thermal ageing on XLPE samples. For this purpose test objects of wire-plane electrode geometry were exposed to various voltage regimes. The obtained results show that a DC pre-stress followed by an application of voltage pulses of opposite polarity appeared most successful for a repeatable inception of electrical trees in the studied materials. Thin tree filaments were formed, distributing randomly at the vicinity of the wire electrode (i.e. high voltage electrode). More trees and longer branches were found in the samples having longer thermal ageing period. These results correlate well with results of in parallel performed tree inception tests under AC voltage ramping. It is therefore postulated that an AC electrical tree inception test can successfully be used for evaluating degradation resistance of materials for HVDC applications.
(An) orexigenic hypothalamic neuropeptides are differentially expressed in high and low feed efficient quail lines (2016)

The livestock and poultry industry is facing numerous challenges to keep up with the increasing demand for high quality animal protein due to the continuously increasing global human population, severe drought conditions around the world, and grains being used for ethanol production. Since feed costs are the majority of the total cost required to produce a live bird, feed efficiency (FE) is a trait of importance. It is beneficial to develop a more deep molecular understanding of the mechanisms that determine feed efficiency. Recently, this study used Japanese quail that were divergently selected for high and low feed efficiency as a model to determine the differential expression of several feeding-related hypothalamic neuropeptides.
