Two modality-based bi-finger vein verification system (2010)

At present, the finger vein has attracted more attention, but the existing finger vein extraction systems are single finger systems, multi-finger case is not yet to come, and few work was did about the research of corresponding verification algorithms. This paper proposes a two modality-based bi-finger vein verification system. Both the finger vein and finger shape could be extracted from the single image acquired from the sensor. The system includes the new finger vein network extraction algorithm. The intersection of the forefinger and middle finger as the origin is introduced to the coordinate system, proposing a method including determining ROI, the finger vein and shape features extraction and its corresponding fusion verification. The experiment shows that the new finger vein network extraction algorithm can extract the finger vein network well. The introduction of the coordinate system effectively solves the problem that not easy to determine ROI, and the false accept rate of bi-pattern fusion verification system is much smaller than the false accept rate of single-feature fusion verification system.

YIELD STRENGTH FILLER METALS AND WELDING PROCEDURES. (1964)

This report reviews the status of (1) the MIG and covered-electrode filler-metal development, and (2) the joining techniques development to date. In the study of the effects of major alloying elements on the properties of MIG weld metals, serious cracking problems were encountered. In the first group of welding wires the problems were traced to carbon levels which were greater than those anticipated from ingot analyses. Experimental covered electrodes of fifteen compositions have been made and six weld metals have been deposited in joints. In addition, a covered-electrode coating study is underway. Work in joining techniques has been directed toward a study of the parameters of the dip-transfer process. The pertinent electrical characteristics of the power supply used in this program have been measured. A number of gases have been screened as to their applicability for use with this process.

A levitation technique for exposing a single particle or group of particles to high temperature gases (1973)

An experimental technique has been developed for exposing particles to gas streams with temperatures in the approximate range 4000-10000 K. The technique is intended for studies of the physical or chemical interactions between particles and gases at high temperatures. Particles are supported by fluid dynamic forces so that mechanical contact is avoided and particles can be electrically nonconducting or conducting. Particle sizes are of the order of hundreds of micrometres. The transparent quartz-containing tube allows particles and gas to be monitored by optical instruments.
Automated high speed stitching of large 3D microscopic images (2011)

High-resolution microscopic imaging of biological samples often produces multiple 3D image tiles to cover a large field of view of specimen. Usually each tile has a large size, in the range of hundreds of megabytes to several gigabytes. For many of our image data sets, existing software tools are often unable to stitch those 3D tiles into a panoramic view, thus impede further data analysis. We propose a simple, but accurate, robust, and automatic method to stitch a group of image tiles without a priori adjacency information of them. We first use a multiscale strategy to register a pair of 3D image tiles rapidly, achieving about 8~10 times faster speed and 10 times less memory requirement compared to previous methods. Then we design a minimum-spanning-tree based method to determine the optimal adjacency of tiles. We have successfully stitched large image stacks of model animals including C. elegans, fruit fly, dragonfly, and mouse, which could not be stitched by several existing methods.
PeerStreaming: A Practical Receiver-Driven Peer-to-Peer Media Streaming System (2004)

We have developed PeerStreaming, a receiver-driven peer-topeer (P2P) media streaming system. Recognizing the fact that the peer is performing a favor for the client and the server during the streaming session, the design philosophy of PeerStreaming is to ensure that the peer is lightweight and the P2P network is loosely coupled. The peer performs simple operations, and may elect to cache only part of the streaming media. It does not collaborate with other peers, may be unreliable and may drop offline or come online during the streaming session. The client coordinates the peers, streams the media from multiple peers, performs load balancing, handles the online/offline of peers, decoding and rendering the media, all in real-time. Through the high rate erasure resilient code, the serving peers may hold partial media without conflict, and the client simply retrieves a fixed number of erasure coded blocks regardless of where and what specific blocks are retrieved. PeerStreaming can stream the embedded coded media, and vary the streaming bitrate according to the serving bandwidths and the client queue status. Via the Microsoft DirectShow framework, PeerStreaming is capable of live P2P streaming, decoding and rendering a number of media format, such as MPEG1/2/4, WMA/WMV, and the embedded media of [10].
Characterization of a Tryptophan 2-Monooxygenase Gene from <i>Puccinia graminis</i> f. sp. <i>tritici</i> Involved in Auxin Biosynthesis and Rust Pathogenicity (2013)

The plant hormone indole-3-acetic acid (IAA) is best known as a regulator of plant growth and development but its production can also affect plant-microbe interactions. Microorganisms, including numerous plant-associated bacteria and several fungi, are also capable of producing IAA. The stem rust fungus Puccinia graminis f. sp. tritici induced wheat plants to accumulate auxin in infected leaf tissue. A gene (Pgt-IaaM) encoding a putative tryptophan 2-monooxygenase, which makes the auxin precursor indole-3-acetamide (IAM), was identified in the P. graminis f. sp. tritici genome and found to be expressed in haustoria cells in infected plant tissue. Transient silencing of the gene in infected wheat plants indicated that it was required for full pathogenicity. Expression of Pgt-IaaM in Arabidopsis caused a typical auxin expression phenotype and promoted susceptibility to the bacterial pathogen Pseudomonas syringae pv. tomato DC3000.

Urinary and serum biomarkers for the diagnosis of acute kidney injury: an in-depth review of the literature* (2012)

Early diagnosing of AKI in clinical conditions by using new serum and urinary biomarkers remains cumbersome, especially in those settings where timing and aetiology of AKI are not well defined. Putting too much emphasis on markers that have not convincingly proven reliability might lead to incorrect interpretation of clinical trials. Further research in this field is warranted before biomarkers can be introduced in clinical practice.
Micro‐vesicles derived from human Wharton's Jelly mesenchymal stromal cells mitigate renal ischemia‐reperfusion injury in rats after cardiac death renal transplantation (2017)

The purpose of the present study was to investigate the possible therapeutic effects of the human Wharton-Jelly mesenchymal stromal cells derived micro-vesicles (hWJMSCs-MVs) on renal ischemia-reperfusion injury (IRI) after cardiac death (CD) renal transplantation in rats. MVs were injected intravenously in rats immediately after renal transplantation. The animals were sacrificed at 24 h, 48 h, 1 and 2 weeks post-transplantation. ELISA was used to determine the von Willebrand Factor (vWF), tumor necrosis factor (TNF)-α, and interleukin (IL)-10 levels in the serum. Tubular cell proliferation and apoptosis were identified by Ki67 immunostaining and TUNEL assay. Renal fibrosis was assessed by Masson's tri-chrome straining and alpha-smooth muscle actin (α-SMA) staining. The infiltration of inflammatory cells was detected by CD68<sup>+</sup> staining. The transforming growth factor (TGF)-β, hepatocyte growth factor (HGF), and α-SMA expression in the kidney was measured by Western blot. After renal transplantation, the rats treated with hWJMSCs-MVs improved survival rate and renal function. Moreover, MVs mitigated renal cell apoptosis, enhanced proliferation, and alleviated inflammation at the first 48 h. In the late period, abrogation of renal fibrosis was observed in the MVs group. MVs also could decrease the number of CD68<sup>+</sup> macrophages in the kidney. Furthermore, MVs decreased the protein expression levels of α-SMA and TGF-β1 and increased the protein expression level of HGF at any point (24 h, 48 h, 1 or 2 weeks). The administration of MVs immediately after renal transplantation could ameliorate IRI in both the acute and chronic stage.

The carbon solubility in Mn-Fe melts were measured at 1 350 ℃,1 375 ℃,1 425 ℃ and 1 450 ℃,and accordingly the calculated equations were obtained. By thermodynamic derivation and calculation, some relationships between thermodynamic parameters for Mn-Fe melt and temperature were obtained.
Purification and Characterization of a Major Allergen from the House Dust Mite <i>Dermatophagoides farinae</i> (1986)

A major allergen from an extract of the house dust mite, Dermatophagoides farinae, was shown to be extremely heterogenic with respect to charge. A slightly basic component of this allergen with a pI of 8, was purified by isoelectric focusing in two steps. The purified component, denoted antigen 19/20 IIa, seemed to be representative for the allergenic activity of the major allergen. The amino acid analysis suggested that antigen 19/20 IIa had a molecular weight of 9400 and contained one residue of galactosamine. SDS polyacrylamide gel electrophoresis did indicate a somewhat higher molecular weight of 14,500. Antibodies against the purified component cross-reacted with a crude extract of the mite Dermatophagoides pteronyssinus.
Improvement of a Microbubble Generator's Performance Via Reliance on Fluid Dynamics Characteristics (2009)

Abstract In present research, improvement of a microbubble generator's performance via reliance on fluid dynamics characteristics is studied numerically, and then some experiments are executed. In an elementary cylindrical microbubble generator, water flow enters the device via six diagonal nozzles, and passes a rotational path around a central motionless hub. This flow breaks the big bubbles entering the device by gas injection from air nozzles. The high-intensity turbulence and shear flow in this device is the cause of the air bubble breaking process. These small bubbles can be used to reduce frictional drag on the contact surface of moving solid bodies in water flow. To improve the operation of the apparatus, some suggested geometrical shapes were investigated numerically and were optimized based on the bubbles' effective breaking-up parameters. The experimental results illustrated good performance of the recent apparatus for generating smaller bubbles.
Thermal conductivity of porous materials: II Theoretical treatment of radiative heat transfer (1990)

A theoretical background relating to radiative heat transfer in porous materials, and the effect on thermal conductivity, is presented. Simplified models are considered as well as a more rigorous analysis provided by the Hamaker two-flux model which takes into account both radiation scattering and absorption. Conventional equations derived from Hamaker assume radiation scattering only, and predict that the radiative conductivity increases with thickness to a limiting value—the 'thickness effect'. A modified expression for radiative conductivity, which includes absorption, has been derived from the Hamaker model. This might be expected to apply to insulants where absorption effects are small compared with those of scattering and which are subject to temperature conditions normally found in the built environment. The radiative conductivity still increases with increasing thickness of insulant. However as the amount of absorption is increased the radiative conductivity is reduced and the limiting value occurs at smaller thicknesses.

Two-dimensional stress wave calculations of kinetic energy projectile impact on multi-layered targets (1977)

The oblique impact of a cylindrical projectile onto a spaced armor target is approximated using two-dimensional elastic-plastic Eulerian and Lagrangian stress wave propagation computer programs. Penetration of the first two armor layers by a tungsten alloy projectile is calculated for a number of different conditions to indicate the effects of varying the armor and projectile yield stress, interface friction and the iron ..cap alpha.. reversible epsilon phase change. Results are summarized by examining changes in projectile residual velocity, projectile rotation and final projectile shape. Calculations with a constant target areal density are also included for a depleted uranium projectile to illustrate the effects of realistic changes in target impedance and strength.
Transdermal Selegiline in Major Depression: A Double-Blind, Placebo-Controlled, Parallel-Group Study in Outpatients (2002)

Transdermal selegiline (20 mg applied once daily by means of a 20-cm(2) patch) administered for 6 weeks was an effective and well-tolerated treatment for adult outpatients with major depression. The typical side effects commonly seen with traditional monoamine oxidase inhibitor antidepressants were not observed.
Conservation patterns in angiosperm rDNA ITS2 sequences (1996)

The two internal transcribed spacers (ITS1 and ITS2) of nuclear ribosomal DNA have become commonly exploited sources of informative variation for interspecific-/intergeneric-level phylogenetic analyses among angiosperms and other eukaryotes. We present an alignment in which one-third to one-half of the ITS2 sequence is alignable above the family level in angiosperms and a phenetic analysis showing that ITS2 contains information sufficient to diagnose lineages at several hierarchical levels. Base compositional analysis shows that angiosperm ITS2 is inherently GC-rich, and that the proportion of T is much more variable than that for other bases. We propose a general model of angiosperm ITS2 secondary structure that shows common pairing relationships for most of the conserved sequence tracts. Variations in our secondary structure predictions for sequences from different taxa indicate that compensatory mutation is not limited to paired positions.
Human activity encoding and recognition using low-level visual features (2009)

Automatic recognition of human activities is among the key capabilities of many intelligent systems with vision/perception. Most existing approaches to this problem require sophisticated feature extraction before classification can be performed. This paper presents a novel approach for human action recognition using only simple low-level visual features: motion captured from direct frame differencing. A codebook of key poses is first created from the training data through unsupervised clustering. Videos of actions are then coded as sequences of super-frames, defined as the key poses augmented with discriminative attributes. A weighted-sequence distance is proposed for comparing two super-frame sequences, which is further wrapped as a kernel embedded in a SVM classifier for the final classification. Compared with conventional methods, our approach provides a flexible non-parametric sequential structure with a corresponding distance measure for human action representation and classification without requiring complex feature extraction. The effectiveness of our approach is demonstrated with the widely-used KTH human activity dataset, for which the proposed method outperforms the existing state-of-the-art. 1
Excitatory amino acid neurotransmission, excitotoxicity and excitotoxins. (1992)

Exciting recent developments have begun to define the molecular basis for excitatory amino acid (EAA) receptor diversity and function. Clarification of the roles of these receptors will require identification of the entire repertoire of EAA subunit genes, the subunit composition of each receptor subtype and the mapping of subunits within the central nervous system (CNS). This may allow the development of selective receptor targeting by therapeutic agents. Further evidence is emerging about the molecular processes underlying excitotoxic injury and the importance of free radical formation acting in concert with calcium-dependent processes is being increasingly recognized. There are many clues indicating that primary or secondary excitotoxic mechanisms may play a part in the pathogenesis of some chronic human neurodegenerative disorders. Further work is needed to clarify the mechanisms of selective vulnerability of particular neuronal types given the widespread distribution of EAA receptors within the CNS.
Isotope effects in peptide group hydrogen exchange (1993)

Kinetic and equilibrium isotope effects in peptide group hydrogen exchange reactions were evaluated. Unlike many other reactions, kinetic isotope effects in amide hydrogen exchange are small because exchange pathways are not limited by bond-breaking steps. Rate constants for the acid-catalyzed exchange of peptide group NH, ND, and NT in H2O are essentially identical, but a solvent isotope effect doubles the rate in D2O. Rate constants for base-catalyzed exchange in H2O decrease slowly in the order NH > ND > NT. The alkaline rate constant in D2O is very close to that in H2O when account is taken of the glass electrode pH artifact and the difference in solvent ionization constant. Small equilibrium isotope effects lead to an excess equilibrium accumulation of the heavier isotopes by the peptide group. Results obtained are expressed in terms of rate constants for the random coil polypeptide, poly-DL-alanine, to provide reference rates for protein hydrogen exchange studies as described in Bai et al. [preceding paper in this issued].

The Psychological Effects of Oxygen Deprivation (Anoxemia) on Human Behavior. (1934)

Part I of this dissertation is an extensive survey of the literature on oxygen want, covering the methods of investigation, the physiologic effects, the symptoms reported by aviators, mountain climbers and miners and the changes in behavior recorded in controlled studies. The author's own research, which is presented in part II, consists of three experiments: the first was made on nine members of the Cambridge University Air Squadron and the second and third were made on seven graduate students and psychologists at Columbia University. While breathing different mixtures of oxygen varying from 11.43 to 7.68 per cent, these subjects attempted simple choice reaction tests, formboard tests and two tests of neuromuscular control. The author concludes that simple sensory and motor responses are not seriously impaired until the subject approaches collapse from oxygen deprivation; but that complex choice reactions are impaired relatively sooner, unless there is some strong incentive, as there
