QoS Support over UWB Mesh Networks (2008)

Streaming and multimedia services are key applications in UWB-based high-rate short-range wireless personal area networks (WPANs). In this paper, we study how to support the quality of service (QoS) requirement of these services over the distributed TDMA-based WiMedia UWB MAC protocol. We develop an integer-linear programming model to solve the path available bandwidth problem. To reduce the computation complexity, a lower bound, an upper bound and an estimation of the path available bandwidth are derived. They are also used as routing metrics to develop a novel QoS routing algorithm to find paths with high available bandwidth. The performance results demonstrate that the lower bound is close to the upper bound and they are even equal to each other in most cases. When used as routing metrics, they can find paths with larger available bandwidth and accommodate more traffic flows than existing ones.
High Conductivity &#x003B4;-Doped Single Crystal Diamond Schottky m-i-p<sup>+</sup> Diodes (2008)

High conductivity 2 kV single crystal diamond Schottky metal-intrinsic-p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> (m-i-p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> ) diodes utilising horizontally and vertically oriented thin highly boron-doped delta layers are presented in this work. Numerical analysis adopting diamond specific models previously reported indicate that these structural modifications drastically improve the forward performance of diamond Schottky diodes, realising current densities up to 50 A/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> for a forward bias of 3 V, without compromising the reverse performance of the device. This is a 20 fold performance improvement from the uniformly intrinsic diamond Schottky diode.
Grundlagen der optischen Kohärenztomographie in der Klinischen Glaukomdiagnostik (2006)

Optical coherence tomography (OCT) supplies morphological information from different retinal layers. In glaucoma, analysis of the nerve fiber layer is gaining more and more significance: Losses in this layer often precede by years functional losses in the visual field and end up in optical nerve head changes. OCT offers a means for imaging and for measurement of the nerve fiber layer besides morphological analysis of ONH as one of the earliest sensitive parameters in modern glaucoma diagnostics. However, because of the lack of extensive comparative data, the priority use of optical coherence morphometry is to be seen mainly in intraindividual follow-up.
A Base Induced Transformation Of A 1,3-Dimethyl-1,3-Di-(1-Adamantyl)Formamidinium Salt Into Beta- Methyl-(1-Adamantyl)Amino Acrylonitriles In Aliphatic Nitriles (2016)

A novel 1,3-dimethyl-1,3-di-(1-adamantyl)formamidinium perchlorate has been prepared via the Vilsmeier-Haack reaction of N-methyl-N-(1-adamantyl)formamide and N-methyl-N-(1-adamantyl) amine in a mixture of phosphorus oxychloride and benzene. The new formamidinium salt was found to undergo addition-elimination reactions when treated with sodium hydride in acetonitrile or propionitrile solution, thereby forming the corresponding beta-[methyl(1-adamantyl)amino]acrylonitriles and N-methyl-N-(1-adamantyl) amine. The H-1 and C-13 NMR spectra and the single-crystal X-ray structure of the new formamidinium salt have been determined along with those of the related compound 1,3-di-(1-adamantyl)-1-cyanoamidine and the corresponding beta-(dialkylamino)acrylonitriles.
Dense Linear Algebra over Finite Fields: the FFLAS and FFPACK packages (2006)

In the past two decades, some major efforts have been made to reduce exact (e.g. integer, rational, polynomial) linear algebra problems to matrix multiplication in order to provide algorithms with optimal asymptotic complexity. To provide efficient implementations of such algorithms one need to be careful with the underlying arithmetic. It is well known that modular techniques such as the Chinese remainder algorithm or the p-adic lifting allow very good practical performance, especially when word size arithmetic are used. Therefore, finite field arithmetic becomes an important core for efficient exact linear algebra libraries. In this paper, we study high performance implementations of basic linear algebra routines over word size prime fields: specially the matrix multiplication; our goal being to provide an exact alternate to the numerical BLAS library. We show that this is made possible by a carefull combination of numerical computations and asymptotically faster algorithms. Our kernel has several symbolic linear algebra applications enabled by diverse matrix multiplication reductions: symbolic triangularization, system solving, determinant and matrix inverse implementations are thus studied.
The disaggregation of calcium‐depleted casein micelles (1988)

The effect of depletion of Ca2+ on the composition and size distribution of casein micelles in milk has been examined using chemical analysis, size exclusion chromatography, fast protein liquid chromatography, turbidimetry and photon correlation spectroscopy. Partial removal of Ca2+ by EDTA and subsequent dialysis resulted in disaggregation of some of the casein micelles; as the EDTA concentration increased, the proportions of Ca2+ and phosphate relative to protein in the micelles remaining intact decreased. However, the composition of the intact micelles, with respect to the different caseins, and the number-frequency size distribution were essentially unchanged.

Lubricant Migration Simulations on the Flying Head Slider Air-Bearing Surface in a Hard Disk Drive (2007)

In this paper, we numerically study the lubricant migration on a flying slider air-bearing surface in a hard disk drive. The lubricant dynamics is based on a continuum thin film lubrication theory with inter-molecular forces and a precursor film model. It includes air-bearing pressure, air-bearing shear stress, the Laplace pressure, the disjoining pressure, and the shear stress caused by the surface free energy gradient. Using this model we investigate the lubricant migration behavior on a modern negative pressure type slider surface. We also reveal the correlation between the lubricant migration behavior and the air-bearing shear stress. We further perform the lubricant migration analysis for various different slider designs, radii, and skew angles.

Memory coherence in shared virtual memory systems (1986)

This paper studies the memory coherence problem in designing and implementing a shared virtual memory on looselycoupled multiprocessors. Two classes of algorithms for solving the problem are presented. A prototype shared virtual memory on an Apollo ring has been implemented based on these algorithms. Both theoretical and practical results show that the memory coherence problem can indeed be solved efficiently on a loosely-coupled multiprocessor.
Temperature Dependence of Pressure Sensitive Paints (1997)

The photoluminescence properties of a typical pressure sensitive paint (PSP) formulation consisting of tris-(4,7-diphenylphenanthrollne)ruthenium(II) dichloride (RudpCl) dispersed in a polydimethylsiloxane (PDMS) binder were examined as a function of temperature. Thus, the temperature dependence of the luminescence intensity I em and emission decay lifetime τ em of the PSP formulation and for the photoluminescent RudpCl dye dissolved in ethanol solvent were determined for temperatures ranging from 5 to 50°C. Analysis of the experimental data indicates that under deoxygenated conditions the temperature dependence of I em and τ em for either the PSP formulation or ethanol solutions is dominated be the intrinsic temperature dependence of the nonradiative decay rate of the photoluminescent dye molecule. By contrast, for the PSP formulation at 1-atm air pressure the temperature dependence of I em and τ em is dominated by the temperature dependence of the diflusivity of oxygen in the PDMS binder. The implications of the experimental results on the design and application of PSP formulations are discussed.

The Crossroads of Synaptic Growth Signaling, Membrane Traffic and Neurological Disease: Insights from Drosophila (2015)

Neurons require target-derived autocrine and paracrine growth factors to maintain proper identity, innervation, homeostasis and survival. Neuronal growth factor signaling is highly dependent on membrane traffic, both for the packaging and release of the growth factors themselves, and for regulation of intracellular signaling by their transmembrane receptors. Here, we review recent findings from the Drosophila larval neuromuscular junction (NMJ) that illustrate how specific steps of intracellular traffic and inter-organelle interactions impinge on signaling, particularly in the bone morphogenic protein, Wingless and c-Jun-activated kinase pathways, regulating elaboration and stability of NMJ arbors, construction of synapses and synaptic transmission and homeostasis. These membrane trafficking and signaling pathways have been implicated in human motor neuron diseases including amyotrophic lateral sclerosis and hereditary spastic paraplegia, highlighting their importance for neuronal health and survival.
The Role of Next-Generation Sequencing in Precision Medicine: A Review of Outcomes in Oncology (2018)

Precision medicine seeks to use genomic data to help provide the right treatment to the right patient at the right time. Next-generation sequencing technology allows for the rapid and accurate sequencing of many genes at once. This technology is becoming more common in oncology, though the clinical benefit of incorporating it into precision medicine strategies remains under significant debate. In this manuscript, we discuss the early findings of the impact of next-generation sequencing on cancer patient outcomes. We investigate why not all patients with genomic variants linked to a specific therapy receive that therapy and describe current barriers. Finally, we explore the current state of health insurance coverage for individual genome sequencing and targeted therapies for cancer. Based on our analysis, we recommend increased transparency around the determination of &amp;ldquo;actionable mutations&amp;rdquo; and a heightened focus on investigating the variations in health insurance coverage across patients receiving sequencing-matched therapies.
Theory of action potential wave block at-a-distance in the heart (2007)

Propagation failure of an action potential wave at a finite distance from its source (so-called type-II block) may cause spiral wave formation or wave breakup in the heart, phenomena that are believed to underlie lethal and nonlethal heart rhythm disorders. In this study, we develop a sufficient condition for this type of block in a homogeneous, spatially one-dimensional system. Using a topological argument, we find that type-II block of a wave will always occur when launched within a finite range of times if the velocity of the trailing edge of the preceding wave, as measured at the stimulus site, is smaller than the velocity of a wave launched with the minimum diastolic interval (DI) for which propagation is possible. This "blocking condition" is robust, remaining valid even when memory and waveback electrotonic effects are included. The condition suggests that type-II block is greatly facilitated when waves are initiated at irregular intervals in time such that (1) the velocities of consecutive waves are as different as possible and (2) the DIs preceding each wave fall on the steeply sloped portion of the action potential duration restitution curve as often as possible. The set of timing intervals between stimuli that are predicted by the blocking condition to produce block are found to be consistent with these guidelines, and also to agree well with a coupled-maps computer simulation model, for the case of waves launched by four rapidly and irregularly timed stimuli.
Computer supported collaborative language learning based on on-line markup (2003)

This paper describes a computer supported communicative correction environment called CoCoA (Communicative Correction Assisting System) that supports teachers and students to exchange marked-up documents via the Internet. Its environment is very similar to a real one in which people use a pen and paper. A correction is an effort to improve a document among teachers and students. There are few systems to manage the correction processes with a computer. We have developed a version management module on CoCoA. This module supports the correction processes. The correction process is a combination of a serial structure and a parallel structure. A parallel structure needs to merge documents corrected by many teachers. However, to merge is particularly difficult as each teacher thinks differently. A semi-automatic merge method and a system to help users are proposed.
NetQuilt: Deep Multispecies Network-based Protein Function Prediction using Homology-informed Network Similarity (2020)

Abstract Transferring knowledge between species is challenging: different species contain distinct proteomes and cellular architectures, which cause their proteins to carry out different functions via different interaction networks. Many approaches to proteome and biological network functional annotation use sequence similarity to transfer knowledge between species. These similarity-based approaches cannot produce accurate predictions for proteins without homologues of known function, as many functions require cellular or organismal context for meaningful function prediction. In order to supply this context, network-based methods use protein-protein interaction (PPI) networks as a source of information for inferring protein function and have demonstrated promising results in function prediction. However, the majority of these methods are tied to a network for a single species, and many species lack biological networks. In this work, we integrate sequence and network information across multiple species by applying an IsoRank-derived network alignment algorithm to create a meta-network profile of the proteins of multiple species. We then use this integrated multispecies meta-network as input features to train a maxout neural network with Gene Ontology terms as target labels. Our multispecies approach takes advantage of more training examples, and more diverse examples from multiple organisms, and consequently leads to significant improvements in function prediction performance. Further, we evaluate our approach in a setting in which an organism’s PPI network is left out, using other organisms’ network information and sequence homology in order to make predictions for the left-out organism, to simulate cases in which a newly sequenced species has no network information available.
On Consumption Function (2005)

Consumption function refers to the relationship between consumption and income. The formula for long term consumption function is C=C_0+bY.Consumption function and saving function are complementary functions to each other.In China,the end consumption takes up a smaller part in the national GDP.The low end consumption rate and low consumption rate for residents in cities and towns are the key factors which restrict the economic development in China.Measures should be taken to constantly improve the consumption rate,and expand consumption needs,so as to promote a faster growing economy.
[Artificial intelligence for diagnostic imaging]. (2020)

Artificial intelligence (AI) is a computer-based system, which in diagnostic imaging can improve patient flow, optimise image processing, shorten scan time, reduce radiation dose and be used as decision aid in image interpretation. In this review, we argue that AI algorithms should be based on evidence with initial hypothesis, then a choice of algorithm and development with training on the initial data set; afterwards the algorithms should be tested on a new representative dataset, and finally it should be tested in a prospective study. If the AI is evidence-based and can solve a task better or cheaper than the usual methodology, it can be implemented.

A clinical update on female androgen insufficiency—testosterone testing and treatment in women presenting with low sexual desire (2006)

The diagnosis of female androgen deficiency syndrome is suggested by complaints of a diminished sense of well being, persistent unexplained fatigue and decreased sexual desire, sexual receptivity and pleasure in a woman who is oestrogen-replete and in whom no other significant contributing factors can be identified. The diagnosis is supported by the finding of low circulating concentrations of free testosterone. Barriers to its recognition include the non-specificity of the symptoms and methodological problems due to insensitive testosterone assays. Barriers to its treatment include the unavailability of satisfactory forms of testosterone for administration to women and lack of data regarding long-term safety. Although several conditions lead to clear-cut androgen deficiency, such as hypopituitarism, adrenal and ovarian insufficiency, glucocorticoid therapy and use of oral contraceptives and oral oestrogens, it is important for clinicians to recognise that in normal women, androgen levels decline by 50% from the early 20s to the mid 40s, and hence age-related androgen insufficiency may occur in women in their late 30s and 40s, as well as postmenopausally. Satisfactory measurements of free testosterone requires a sensitive and reliable assay for total testosterone, and quantitation of sex hormone binding globulin, from which free testosterone is readily calculated. Adverse effects of testosterone treatment are few if replacement is monitored to achieve physiological circulating testosterone concentrations. Currently, available methods include testosterone implants and testosterone creams, and transdermal patches and sprays are in development.

Fast Full-Wave Analysis of Damaged Periodic Fiber-Reinforced Laminates (2018)

A computationally efficient modeling approach to analyze transverse magnetic and transverse electric electromagnetic scattering from periodic fiber-reinforced laminates is introduced, when they suffer from missing, shrunk/expanded, displaced fibers, and inclusions. Such damages inside the initially periodic structure (the fibers as organized in a given matrix) are seen as undamaged zones with fictitious line sources properly set inside them, and the field results as a summation of responses to the exterior source and equivalent ones. Then, methods for periodic structures can readily be used. Various numerical results are proposed which are evidencing the interest of this approach.
The Myth of the Overworked American (1995)

A challenge to the popular presumption that U.S. workers are experiencing declining levels of leisure time, finding that the total hours of work have not changed much over the past decade, but that the composition of labor has shifted from home work to market work, mostly as a result of changes in the total hours worked by women.
Structural and resistance switching properties of ZnO/SrTiO3/GaAs heterostructure grown by laser molecular beam epitaxy (2010)

ZnO thin films were epitaxially grown on (001) GaAs substrate by laser molecular beam epitaxy with SrTiO3 (STO) as a buffer layer. The interface properties of ZnO/GaAs heterostructure are greatly improved by inserting STO buffer layer. The interfacial effects on the transport and dielectric characteristics of the heterostructure have been investigated. The current-voltage characteristic of the heterostructure reveals an asymmetric and resistance switching behavior, exhibiting a temperature-dependent resistance hysteresis in the temperature range of 50–300 K. These measured properties could be attributed to the charge effect at the interface of the heterostructure.
The design of approximate Hilbert transform pairs of wavelet bases (2002)

Several authors have demonstrated that significant improvements can be obtained in wavelet-based signal processing by utilizing a pair of wavelet transforms where the wavelets form a Hilbert transform pair. This paper describes design procedures, based on spectral factorization, for the design of pairs of dyadic wavelet bases where the two wavelets form an approximate Hilbert transform pair. Both orthogonal and biorthogonal FIR solutions are presented, as well as IIR solutions. In each case, the solution depends on an allpass filter having a flat delay response. The design procedure allows for an arbitrary number of vanishing wavelet moments to be specified. A Matlab program for the procedure is given, and examples are also given to illustrate the results.
