A two-stage solution algorithm for paroxysmal atrial fibrillation prediction (2002)

We propose a two-stage solution algorithm to predict the onset of paroxysmal atrial fibrillation (PAF) based on half-hour heart rate variability (HRV) signals. Nonlinear feature based on vectors calculated from return map and difference map constructed by HRV signal were developed. The extracted features were fed into their corresponding nearest-neighbor classifiers for parameter adjustment and classification. According to the official scoring results, our algorithm scored 34 points in the screening stage and 40 points in the prediction stage. In addition, the developed algorithm appears to he very robust against measuring noises. For example, with different QRS defectors, the classification results only change slightly (within 5%).
Streamlined Process for the Chemical Synthesis of RNA Using 2′-<i>O</i>-Thionocarbamate-Protected Nucleoside Phosphoramidites in the Solid Phase (2011)

An improved method for the chemical synthesis of RNA was developed utilizing a streamlined method for the preparation of phosphoramidite monomers and a single-step deprotection of the resulting oligoribonucleotide product using 1,2-diamines under anhydrous conditions. The process is compatible with most standard heterobase protection and employs a 2'-O-(1,1-dioxo-1λ(6)-thiomorpholine-4-carbothioate) as a unique 2'-hydroxyl protective group. Using this approach, it was demonstrated that the chemical synthesis of RNA can be as simple and robust as the chemical synthesis of DNA.
Image matching algorithm based on lifting wavelet transform and improved space projection (2009)

The anti-noise ability is not strong enough for the image matching in standard projection algorithm,so a new algorithm based on both lifting wavelet transform and improved space projection is proposed.First,we get the multi-resolution images by using lifting wavelet transform and make the low-resolution image matchings with space projection algorithm,then apply the obtained rough-matched candidates to higher resolution matching.The precise matching is fulfilled with normalized intensity correlation algorithm.Simulation results show that the algorithm is with high matching accuracy and robustness,being compared with other algorithms.
A mobile-agent based wireless sensing network for structural monitoring applications (2008)

Abstract: A new wireless sensing network paradigm is presented for structural monitoring applications. In this approach, both power and data interrogation commands are conveyed via a mobile-agent that is sent to sensor nodes to perform intended interrogations, which can alleviate several limitations of the traditional sensing networks. Furthermore, the mobile-agent provides computation power to make near real-time assessments on the structural conditions. This paper will discuss such prototype systems, which are used to interrogate impedance-based sensors for structural health monitoring applications. Our wireless sensor node is specifically designed to accept various energy sources, including wireless energy transmission, and to be wirelessly triggered on an as-needed basis by the mobile-agent or other sensor nodes. The capabilities of this proposed sensing network paradigm are demonstrated in the laboratory and the field.
Electrochemical study of the influence of H<sub>2</sub>O<sub>2</sub>on 316L stainless steel implants in Hank’s solution at body temperatures (2014)

The stability of the oxide layer at the surface of stainless steel is very important to protect medical implants, knowing that chemical product like hydrogen peroxide can change its behaviour. When used medical implants go through various steps in which hydrogen peroxide is involved. Corrosion of 316L stainless steel implant in Hank’s solution at body temperatures was evaluated for different concentrations of hydrogen peroxide. Open circuit potential (OCP) and potentiodynamic tests were carried out. According to the results, when the concentration of H2O2 is increased, the potential becomes more positive but the passive layer formed at the surface of the implant remains unstable. Independently of hydrogen peroxide concentration, the corrosion potential shifts to more negative values proportionally to the increase of immersion times from 0 to 72 h. When immersions are superior to 72 h, in the presence of high hydrogen peroxide concentrations, the breakdown potential increase positively with the increase of the immersion time (ennoblement occurs). Rising Hank’s solution temperature containing H2O2 from 37 °C to 42 °C increased pitting corrosion of 316L SS implant. Micrographs taken after polarization, showed a particular layout of pits which may explain the stainless steel implants rupture and lead to the improvement of their elaboration.
Ill conditioning in self-heating FET models (2002)

This paper shows that the introduction of self heating effects into a FET model can cause severe ill conditioning in nonlinear circuit simulators. Depending on the parameter values of the model, the solutions can be indistinct, multiple, or even nonexistent. The result is poor convergence in nonlinear simulations using such models.
BGS Sigma 2012 open source user guide (2013)

The British Geological Survey began developing digital field mapping systems in 1989. However, it was apparent that the commercially available hardware was not suitable at that time. In 2001, we revisited the topic under the System for Integrated Geoscience Mapping (SIGMA) programme. By 2003, BGS had developed a PDA (personal digital assistant) field system, which was superseded in 2005, when we began deploying a beta system on rugged Tablet PCs. The Tablet PC system, which we called BGS•SIGMAmobile was used by BGS in mapping projects across the UK as well as overseas. It first became available in Open Source form, in June 2009 via the BGS website, www.bgs.ac.uk, under an agreement which stipulates that updates and modifications must be supplied to BGS in order to stimulate further developments. In 2011/2012, BGS•SIGMAmobile was rewritten in .NET and combined with our office based mapping software BGS•SIGMAdesktop within ArcGIS 10.x to create BGS•SIGMA 2012.
It is envisaged that future releases will be made available from the BGS website incorporating new modules, modifications and upgrades supplied by BGS and external users of the system.
This document has been written to guide users through the installation and use of BGS•SIGMA 2012 (mobile and desktop), which is the third free release.
We are happy to receive feedback and modifications emailed to sigma@bgs.ac.uk.
A new optimizer for the facility layout problem (2005)

Facility layout problem is one of the truly difficult combinatorial optimization problems that remain unsolved. The task is to assign facilities to locations in a manner so as to minimize a total cost function. In this paper, the authors propose a new global optimization technique, which makes combined use of evolutionary programming and simulating annealing. Experimental results for the standard benchmark problems are reported and the results show that the authors proposed algorithm compares favorably with other heuristic algorithms.

Fundamental Study on Mechanisms of Thermal Decomposition and Oxidation of Aluminum Hydride (2019)

Aluminum hydride (AlH3) has great potential for a variety of propulsion and energy-storage applications. In this study, the ReaxFF reactive force field molecular dynamics simulation is employed to investigate the fundamental reaction mechanisms of thermal decomposition and oxidation of AlH3. The effects of an oxide layer and/or defect are examined, and the detailed process and mechanism of H2 and H2O formation are illustrated. With the presence of an oxide layer, H2 production of core–shell AlH3 during the thermal decomposition is slower than that of bare AlH3. As far as oxidation is concerned, any defect enhances the initiation of core–shell AlH3 oxidation and accelerates the oxidation at the early stage of the reaction. Additionally, the presence of O2 promotes the production of OH. Both thermal decomposition and oxidation of core–shell AlH3 show significant H2O production, and H2O is preferentially formed compared with H2 at the beginning of the reaction. The results reveal that the structural evolution of core–shell AlH3 during the thermal decomposition and oxidation proceeds in three distinctive stages, respectively. It is found that during the oxidation, dehydrogenation and oxidation proceed simultaneously although the oxidation rate is limited during the dehydrogenation period.
Differing effects of substrate and non‐substrate transport inhibitors on glutamate uptake reversal (2001)

Na(+)-dependent excitatory amino acid transporters (EAATs) normally function to remove extracellular glutamate from brain extracellular space, but EAATs can also increase extracellular glutamate by reversal of uptake. Effects of inhibitors on EAATs can be complex, depending on cell type, whether conditions favor glutamate uptake or uptake reversal and whether the inhibitor itself is a substrate for the transporters. The present study assessed EAAT inhibitors for their ability to inhibit glutamate uptake, act as transporter substrates and block uptake reversal in astrocyte and neuron cultures. L-threo-beta-hydroxyaspartate (L-TBHA), DL-threo-beta-benzyloxyaspartate (DL-TBOA), L-trans-pyrrolidine-2,4-dicarboxylic acid (L-trans-2,4-PDC) (+/-)-cis-4-methy-trans-pyrrolidine-2,4-dicarboxylic acid (cis-4-methy-trans-2,4-PDC) and L-antiendo-3,4-methanopyrrolidine-2,4-dicarboxylic acid (L-antiendo-3,4-MPDC) inhibited L-[14C]glutamate uptake in astrocytes with equilibrium binding constants ranging from 17 microM (DL-TBOA and L-TBHA) - 43 microM (cis-4-methy-trans-2,4-PDC). Transportability of inhibitors was assessed in astrocytes and neurons. While L-TBHA, L-trans-2,4-PDC, cis-4-methy-trans-2,4-PDC and L-antiendo-3,4-MPDC displayed significant transporter substrate activities in neurons and astrocytes, DL-TBOA was a substrate only in astrocytes. This effect of DL-TBOA was concentration-dependent, leading to complex effects on glutamate uptake reversal. At concentrations low enough to produce minimal DL-TBOA uptake velocity (< or = 10 microM), DL-TBOA blocked uptake reversal in ATP-depleted astrocytes; this blockade was negated at concentrations that drove substantial DL-TBOA uptake (> 10 microM). These findings indicate that the net effects of EAAT inhibitors can vary with cell type and exposure conditions.
EVALUATION OF RNA QUALITY FROM FORMALIN FIXED AND PARAFFIN EMBEDDED SAMPLES:APPLICATIONS AND LIMITATIONS (2009)

No proposed solutions in this document are intended as standards for the ARPA-Internet at this time. Rather, it is hoped that a general consensus will emerge as to the appropriate solution to such problems, leading eventually to the adoption of standards. Distribution of this memo is unlimited.
Fundamentals of Orbifolds (2007)

A key tool that allows for connecting Sasakian structures to other geometric structures is the theory of Kähler orbifolds and their orbifold bundles or ‘orbibundles’. Orbifolds, just as manifolds, have become a household name to the well trained geometer. Nevertheless, a lot of important results are scattered throughout the literature, and orbifolds typically appear within a specific context. This chapter introduces all the basic concepts from the point of view needed in subsequent chapters such as orbibundles, orbifold homology, and cohomology theory and orbifold characteristic classes. Priority is given to the theory of complex algebraic orbifolds, with a detailed discussion concerning branch divisors and the orbifold canonical divisor and orbibundle. Weighted projective spaces and hypersurfaces in them also play a prominent role.
Sensing temperature in CMOS circuits for thermal testing (2004)

Temperature is a physical magnitude that can be used as an observable quantity for IC testing purposes. The authors discuss in this paper the suitability of two temperature measuring strategies applicable to standard CMOS integrated circuits: a laser interferometer and a differential fully CMOS built-in temperature sensor.
Energy minimization for self-organized structure formation and actuation (2007)

An approach for creating complex structures with embedded actuation in planar manufacturing steps is presented. Self-organization and energy minimization are central to this approach, illustrated with a model based on minimization of the hyperelastic free energy strain function of a stretched elastomer and the bending elastic energy of a plastic frame. A tulip-shaped gripper structure illustrates the technological potential of the approach. Advantages are simplicity of manufacture, complexity of final structures, and the ease with which any electroactive material can be exploited as means of actuation.
Peripheral selection of antigen receptor junctional features in a major human γδ subset (1993)

Recent studies demonstrating the existence of murine gamma delta T cell subsets with structurally identical T cell receptors (TcR) suggest that unlike alpha beta T cells, some gamma delta T cells are specialized in the recognition of a limited number of monomorphic antigens. However, this question still remains open in humans, since the TcR structural diversity of their peripheral gamma delta T cells was shown to be extensive. Here we have analyzed in detail the TcR chain genes expressed by human V gamma 9+V delta 2+ peripheral blood lymphocytes (PBL), a major peripheral gamma delta T cell subset in adults and present evidence for an antigen-driven peripheral selection of both TcR gamma and delta junctional motifs among these cells. First, it is shown that the proportion of V gamma 9+V delta 2+ cells expressing the V9JPC1 gamma chain is much higher among PBL than among thymus-derived clones, indicating that preferential use of this J gamma segment is not due to pairing or combinatorial constraints. Second, analysis of V9JPC1 gamma transcripts derived from V gamma 9+V delta 2+ PBL clones revealed a high prevalence of a unique V9JP gamma sequence with limited "N" nucleotide additions and VJ trimming, which could not be accounted for by enzymatic or antigen-independent structural limitations. Third, the TcR delta chain expressed by most V gamma 9+V delta 2+ PBL clones, though diverse in amino acid composition and length, carried a highly distinctive junctional motif, found at a much lower frequency among V2DJ delta sequences derived from V gamma 9-V delta 2+ PBL or V gamma 9+V delta 2+ thymocytes. Together, these results which demonstrate shared gamma and delta junctional features by cells using unique V gamma and V delta genes, suggest that in vivo selection of V gamma 9+V delta 2+ lymphocytes is mediated by a highly restricted number of nominal ligands.

Repeat Buyer Prediction for E-Commerce (2016)

A large number of new buyers are often acquired by merchants during promotions. However, many of the attracted buyers are one-time deal hunters, and the promotions may have little long-lasting impact on sales. It is important for merchants to identify who can be converted to regular loyal buyers and then target them to reduce promotion cost and increase the return on investment (ROI). At International Joint Conferences on Artificial Intelligence (IJCAI) 2015, Alibaba hosted an international competition for repeat buyer prediction based on the sales data of the ``Double 11" shopping event in 2014 at Tmall.com. We won the first place at stage 1 of the competition out of 753 teams. In this paper, we present our winning solution, which consists of comprehensive feature engineering and model training. We created profiles for users, merchants, brands, categories, items and their interactions via extensive feature engineering. These profiles are not only useful for this particular prediction task, but can also be used for other important tasks in e-commerce, such as customer segmentation, product recommendation, and customer base augmentation for brands. Feature engineering is often the most important factor for the success of a prediction task, but not much work can be found in the literature on feature engineering for prediction tasks in e-commerce. Our work provides some useful hints and insights for data science practitioners in e-commerce.
Effect of Application Added Phosphorus and Potassium for Potato and Chinese Cabbage in Mounded Highland Soil (2002)

This study was conducted to investigate the changes of soil properties for potato and Chinese cabbage after application adding phosphorus and potassium fertilizers in the mounded highland soil from 1999 to 2001. Experimental plots were designed with control(NPK+Lime+Compost) and chemical improvement(Control+Application adding P and K). Mounded soil before field experiment of first year(1999) was low in organic matter, available phosphorus and exchangeable potassium, and the soil texture was loamy sand soil. After 3 years, the contents of soil organic matter increased a little, and available phosphorus and exchangeable potassium contents were remarkably increased. The crop growth in chemical improvement plot was better than control plot. Yield of chemical improvement plot in comparison with control plot was increased by 5~22% for potato and 6~25% for Chinese cabbage after 2~3 years.
<title>Polarization-based fiber optic delay lines</title> (1995)

Multichannel fiber-optic delay line architectures using optical polarization switching are proposed that use nonpolarization maintaining single-mode fibers while still maintaining high extinction polarization properties of the switched optical beams. Critical birefringence compensation and noise reduction techniques are introduced and demonstrated for these delay lines showing high optical polarization extinction (> 39 dB) and electrical signal-to-noise ratio (> 92 dB) results.
Signal Transduction by CD28 Costimulatory Receptor on T Cells (1996)

This study compares the biochemical responses in T cells activated with the CD28 ligands B7-1 and B7-2. The patterns of tyrosine phosphorylation induced in T cells by these two CD28 ligands are identical, but clearly different from the tyrosine phosphorylation induced by the T cell receptor (TCR). The TCR regulates protein complexes mediated by the adapter Grb2 both in vivo and in vitro. In contrast, there is no apparent regulation of in vivo Grb2 complexes in response to B7-1 or B7-2. Rather, B7-1 and B7-2 both induce tyrosine phosphorylation of a different adaptor protein, p62. The regulation of p62 is a unique CD28 response that is not shared with the TCR. These data indicate that B7-1 and B7-2 induce identical tyrosine kinase signal transduction pathways. The data show also that the TCR and CD28 couple to different adapter proteins, which could explain the divergence of TCR and CD28 signal transduction pathways during T cell activation.
Gene therapy for primary immunodeficiency disease. (1992)

Gene therapy offers the potential for developing innovative new treatments for both inherited monogenic diseases as well as polygenic and acquired disorders. For most potential clinical applications, the technology has not yet progressed to the stage where it might be reasonably tested. Problems to be solved include the isolation and characterization of the genes involved, the development of gene delivery systems that will permit efficient gene insertion in the affected cells and tissues, and the development of mechanisms to control or appropriately regulate expression of the introduced genes. The primary immunodeficiency diseases as a group actually lend themselves to the development of gene therapy strategies with current technology more readily than almost any other class of disease. Theoretically any genetic disease that can be successfully treated by allogeneic bone marrow transplantation is a potential candidate for gene therapy directed at correcting the patient's own totipotent bone marrow stem cells. In addition, some disorders lend themselves to genetic correction of more mature cells, although gene transfer in this treatment strategy might have to be repeated periodically. The rationale and preliminary results of the first gene therapy protocol for ADA deficiency SCID are described and strategies for developing somatic cell gene therapy for the other primary immunodeficiency diseases are discussed.
