Face recognition from one example view (2002)

To create a pose-invariant face recognizer, one strategy is the view-based approach, which uses a set of real example views at different poses. But what if we only have one real view available, such as a scanned passport photo-can we still recognize faces under different poses? Given one real view at a known pose, it is still possible to use the view-based approach by exploiting prior knowledge of faces to generate virtual views, or views of the face as seen from different poses. To represent prior knowledge, we use 2D example views of prototype faces under different rotations. We develop example-based techniques for applying the rotation seen in the prototypes to essentially "rotate" the single real view which is available. Next, the combined set of one real and multiple virtual views is used as example views for a view-based, pose-invariant face recognizer. Oar experiments suggest that among the techniques for expressing prior knowledge of faces, 2D example-based approaches should be considered alongside the more standard 3D modeling techniques.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Adenosine triphosphate deficiency (1995)

The relatively prompt improvement and the eventual complete recovery of vision following vitamin replacement therapy suggest that the subnormal level of vitamin B12 precipitated visual loss. Given the clinical similarities of subnormal vitamin B12, LHON, and nutritional/tobacco amblyopia, deficiency of adenosine triphosphate might be a unifying etiology for several types of optic neuropathy. This energy hypothesis provides a theoretical basis for the enigmatic phenomena of centrocecal scotomata and recovery of visual function after prolonged blindness.
Automated unsupervised multi‐parametric classification of adipose tissue depots in skeletal muscle (2012)

The proposed multi-parametric segmentation approach combined with quantitative water-fat imaging provides an accurate and reliable method for an automated calculation of the SAT and IMAT areas reducing considerably the total postprocessing time.
Differentiation therapy: targeting breast cancer stem cells to reduce resistance to radiotherapy and chemotherapy (2010)

Retrospective studies on male breast cancer (MBC) have suff ered from small numbers of cases available from any one centre; thus a signifi cant problem in eff ectively studying this disease is accruing suffi ciently large numbers to allow comparative analysis of biomarkers associated with response. Using a coordinated multicentre approach, we present the fi rst large-scale study to address the relevance of the expression of hormone receptors in MBC and female breast cancer (FBC) using immunohistochemistry combined with a novel bioinformatics approach. Following ethical approval, 523 archival blocks (260 MBCs and 263 matched FBCs) were obtained retrospectively. Tissue microarrays were constructed and sections stained for ER, ER1, ER2, ER5, total PR, PRA, PRB and AR and typed using CK5/6, CK14, CK18 and CK19 by immunohistochemistry. Following scoring, a range of ordination techniques were conducted on the datasets including hierarchical clustering and principal component analysis (PCA) to determine the diff erential nature of infl uences and interactions between MBC and FBC. Luminal A subgroup (ER + and/or PR + , HER2 -) was the most common phenotype in both sexes. Luminal B (ER + and/or PR + , HER2 + ) was not seen in males, while basal-like tumours (ER -, PR -, HER2 -, CK5/6 + ) were infrequent in both. Hierarchical clustering revealed common clusters between MBC and FBC including total PR-PRA-PRB and ER1/2 clusters. ER occurred on distinct clusters between males and females. AR, ER1, ER2 and ER5 all existed on the same cluster but with a diff erent substructure, particularly around the positioning of AR. ER associated with this cluster in the male but not the female group. PCA confi rmed that in both groups strong infl uences came from PR-PRA-PRB. In MBC strong infl uences additionally came from AR and ER1, ER2 and ER5, whereas in FBC strong infl uences came from ER alone. Our data support the hypothesis that breast cancer is biologically diff erent in male and females, which could have implications for therapy.
Rice Aspartic Proteinase, Oryzasin, Expressed During Seed Ripening and Germination, has a Gene Organization Distinct from Those of Animal and Microbial Aspartic Proteinases (1995)

The gene organization and nucleotide sequence of an aspartic proteinase (AP) of plant origin were first disclosed by cDNA and genomic DNA cloning of a rice AP (oryzasin). The deduced amino acid sequence of oryzasin 1 was significantly similar to those of other APs (34-85%), with highest similarity (85%) to barley AP (HvAP). Oryzasin 1, as well as HvAP, is distinct from animal and microbial APs in that the plant APs contain a unique 104-amino-acid insertion in the C-terminal region. The oryzasin 1 gene spans approximately 6.6 kbp and is composed of 14 exons and 13 introns. The exon-intron organization of the oryzasin 1 gene is totally different from those of genes for animal and microbial APs such as human cathepsin D, rat renin, bovine chymosin, aspergillopepsin A of Aspergillus awamori, proteinase A of Saccharomyces cerevisiae and rhizopuspepsin of Rhizopus niveus, despite the fact that oryzasin 1 shows overall sequence similarity to these APs.

Ion Coordinating Sensitizer for High Efficiency Mesoscopic Dye-Sensitized Solar Cells:  Influence of Lithium Ions on the Photovoltaic Performance of Liquid and Solid-State Cells (2006)

A Li+ coordinating sensitizer, NaRu(4-carboxylic acid-4'-carboxylate)(4,4'-bis[(triethylene glycol methyl ether) methyl ether]-2,2'-bipyridine)(NCS)2 (coded as K51), has been synthesized, and the effect of Li+ coordination on its performance in mesoscopic titanium dioxide dye-sensitized solar cells has been investigated. Fourier transform infrared spectra suggest that Li+ coordinates to the triethylene oxide methyl ether side chains on the dye molecules. With the addition of Li+ to a nonvolatile liquid electrolyte, we observe a significant increase in the photocurrent density, with only a small decrease in the open-circuit voltage, contrary to a non ion coordinating dye which displays a large drop in potential with the addition of Li+. For a solar cell incorporating an organic hole-transporter, we find the potential rises with increasing the Li+ concentration in the hole-transporter matrix. For the liquid electrolyte and solid-state cells, we obtain power conversion efficiencies of 7.8% and 3.8%, respectively, under simulated sunlight.

Low Temperature Deposition of TiN Ceramic Material by Metal Organic and/or Plasma Enhanced CVD (1995)

A review is presented describing the development of TiN-CVD from the classical, high temperature TiCl4/N2 process, towards low temperature MOCVD processes. This development is presented from a chemical point of view. In addition to low pressure (LPCVD) and atmospheric pressure (APCVD) thermal processing, also plasma enhanced (PECVD) techniques are described. In the past few years production facilities for good quality TiN layers for wear resistant applications have come on the market. Production facilities for IC-technology applications of CVD-TiN are on the edge of breaking through. For both applications deposition temperatures have been reduced to 500-600°C. Research developments, have shown even lower deposition temperatures possible for TiN and Ti(C,N) layers.
Computer reconstruction of 2-D photographs from alternative viewpoints (1990)

The reconstruction of mug-shots from various angles has obvious advantages where witnesses are attempting to identify a subject who may have been observed from a viewpoint other than that recorded on a frontal photograph. Alternatively, the ability to modify a frontal photograph in such a way that it allows reconciliation of the photograph and views of the subject as seen by witnesses from different viewpoints, has the potential to lead to a more accurate description of the subject being obtained. Both of these applications are facilitated by a computer graphics technique described, in which an image, held in computer memory, of a frontal facial photograph, is texture mapped onto the surface of an underlying 3D skeletal model.
Psychotherapeutic Benefits of Opioid Agonist Therapy (2008)

Opioids have been used for centuries to treat a variety of psychiatric conditions with much success. The so-called "opium cure" lost popularity in the early 1950s with the development of non-addictive tricyclic antidepressants and monoamine oxidase inhibitors. Nonetheless, recent literature supports the potent role of methadone, buprenorphine, tramadol, morphine, and other opioids as effective, durable, and rapid therapeutic agents for anxiety and depression. This article reviews the medical literature on the treatment of psychiatric disorders with opioids (notably, methadone and buprenorphine) in both the non-opioid-dependent population and in the opioid-dependent methadone maintenance population. The most recent neurotransmitter theories on the origin of depression and anxiety will be reviewed, including current information on the role of serotonin, N-Methyl d-Aspartate, glutamate, cortisol, catecholamine, and dopamine in psychiatric disorders. The observation that methadone maintenance patients with co-existing psychiatric morbidity (so called dual diagnosis patients) require substantially higher methadone dosages by between 20% and 50% will be explored and qualified. The role of methadone and other opioids as beneficial psychiatric medications that are independent of their drug abuse mitigating properties will be discussed. The mechanisms by which methadone and other opioids can favorably modulate the neurotransmitter systems controlling mood will also be discussed.
Catalysis of the methanolysis of acetylimidazole by lanthanum triflate (2000)

Methanolysis of acetylimidazole (1) and N-acetylimidazolepentamine-Co(III) (2) was found to be markedly accelerated in the presence of La(OTf) 3 . Potentiometric titration of a solution of La 3+ (OTf - ) 3 gave a pK a for the metal bound CH 3 OH of 7.22. The kinetics of methanolysis of 1 and 2 were measured at 25°C at various pH under buffered conditions as a function of increasing La 3+ . Analysis of both the kinetic and potentiometric data indicates that the catalytically active species is a La 3+ -dimer, bridged by two methoxides, (CH 3 OH) n La 3+ (CH 3 O - ) 2 La 3+ (CH 3 OH) n . The maximum second-order rate constants for attack of the dimer on 1 and 2 are 1.50 × 10 3 M -1 s -1 and 1.42 × 10 2 M -1 s -1 respectively and both processes adhere to titration of a La 3+ (CH 3 OH) to generate the active form. The results are explained in terms of a mechanism where the methoxy-bridged La 3+ dimer transiently breaks a La 3+ -OCH 3 bond to expose both a CH 3 O - nucleophile and a La 3+ which can act as a Lewis acid. Unlike the situation in water, the methanol results indicate that the medium greatly stabilizes and solubilizes the active dimer without the necessity of creating specially designed ligands to stabilize the dinuclear core.Key words: lanthanum ion, catalysis, methanolysis, activated amide.
A Study on Keepalive Mechanism between SIP UA and Proxy server for Internet Telephony Service (2007)

When Internet telephony service is provided using SIP protocol, The session initiation protocol (SIP) does not define a keepalive mechanism for the sessions it establishes. Although the user agents may be able to determine whether the session has timed out by using session specific mechanisms, proxies will not be able to do so. The result is that call stateful proxies will not always be able to determine whether a session is still active.
Programmable bus/memory controllers in modern computer architecture (2005)

This paper proposes a design for a fully programmable bus/memory controller. It enumerates the various advantages of such a controller, and demonstrates how modern memory models, common processor applications, and evolving operating system utilities point towards the use of the programmable controller as the next step forward in computer architecture. It also aims to evaluate the concerns that such a controller must take. Finally, It addresses a number of possible applications of a programmable controller, giving qualitative and quantitative analysis and sample implementations of several applications.
Discriminative Feature Co-Occurrence Selection for Object Detection (2008)

This paper describes an object detection framework that learns the discriminative co-occurrence of multiple features. Feature co-occurrences are automatically found by Sequential Forward Selection at each stage of the boosting process. The selected feature co-occurrences are capable of extracting structural similarities of target objects leading to better performance. The proposed method is a generalization of the framework proposed by Viola and Jones, where each weak classifier depends only on a single feature. Experimental results obtained using four object detectors, for finding faces and three different hand gestures, respectively, show that detectors trained with the proposed algorithm yield consistently higher detection rates than those based on their framework while using the same number of features.
Inhibition of Cell Growth and Spreading by Stomach Cancer-associated Protein-tyrosine Phosphatase-1 (SAP-1) through Dephosphorylation of p130 (2001)

SAP-1 (stomach cancer-associated protein-tyrosine phosphatase-1) is a transmembrane-type protein-tyrosine phosphatase that is abundant in the brain and certain cancer cell lines. With the use of a "substrate-trapping" approach, p130(cas), a major focal adhesion-associated phosphotyrosyl protein, has now been identified as a likely physiological substrate of SAP-1. Expression of recombinant SAP-1 induced the dephosphorylation of p130(cas) as well as that of two other components of the integrin-signaling pathway (focal adhesion kinase and p62(dok)) in intact cells. In contrast, expression of a substrate-trapping mutant of SAP-1 induced the hyperphosphorylation of these proteins, indicating a dominant negative effect of this mutant. Overexpression of SAP-1 induced disruption of the actin-based cytoskeleton as well as inhibited various cellular responses promoted by integrin-mediated cell adhesion, including cell spreading on fibronectin, growth factor-induced activation of extracellular signal-regulated kinase 2, and colony formation. Finally, the enzymatic activity of SAP-1, measured with an immunocomplex phosphatase assay, was substantially increased by cell-cell adhesion. These results suggest that SAP-1, by mediating the dephosphorylation of focal adhesion-associated substrates, negatively regulates integrin-promoted signaling processes and, thus, may contribute to contact inhibition of cell growth and motility.
A dual-rate self-tuning pole-placement controller (1993)

A dual-rate self-tuning pole-placement controller is proposed. It allows the use of a larger sampling interval for on-line parameter estimation and a smaller sampling interval for control. The conversion of model parameters from one sampling interval to another can be readily performed using a pole-zero mapping technique. The major problem encountered is that the process zeros at the slow sampling rate cannot be estimated accurately by using input-output data obtained at the fast sampling rate. The proposed solution of fixing the zeros at z=-1 while keeping the DC gain the same is supported by analysis of the Nyquist plot. The main merits of the dual-rate self-tuning control system are in the simultaneous achievement of robust estimation and reduced computation load and in improved performance in the regulation of deterministic and stochastic load disturbances. Its performance is substantiated by digital simulation and experiments on a pilot plant.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Solubilized extracellular matrix bioscaffolds derived from diverse source tissues differentially influence macrophage phenotype (2016)

The host response to biomaterials is a critical determinant of their success or failure in tissue-repair applications. Macrophages are among the first responders in the host response to biomaterials and have been shown to be predictors of downstream tissue remodeling events. Biomaterials composed of mammalian extracellular matrix (ECM) in particular have been shown to promote distinctive and constructive remodeling outcomes when compared to their synthetic counterparts, a property that has been largely attributed to their ability to modulate the host macrophage response. ECM bioscaffolds are prepared by decellularizing source tissues such as dermis and small intestinal submucosa. The differential ability of such scaffolds to influence macrophage behavior has not been determined. The present study determines the effects of ECM bioscaffolds derived from eight different source tissues upon macrophage surface marker expression, protein content, phagocytic capability, metabolism, and antimicrobial activity. The results show that macrophages exposed to small intestinal submucosa (SIS), urinary bladder matrix (UBM), brain ECM (bECM), esophageal ECM (eECM), and colonic ECM (coECM) express a predominant M2-like macrophage phenotype, which is pro-remodeling and anti-inflammatory (iNOS-/Fizz1+/CD206+). In contrast, macrophage exposure to dermal ECM resulted in a predominant M1-like, pro-inflammatory phenotype (iNOS+/Fizz1-/CD206-), whereas liver ECM (LECM) and skeletal muscle ECM (mECM) did not significantly change the expression of these markers. All solubilized ECM bioscaffold treatments resulted in an increased macrophage antimicrobial activity, but no differences were evident in macrophage phagocytic capabilities, and macrophage metabolism was decreased following exposure to UBM, bECM, mECM, coECM, and dECM. The present work could have important implications when considering the macrophage response following ECM implantation for site-appropriate tissue remodeling. © 2016 Wiley Periodicals, Inc.

Effects of the cold pressor test on muscle sympathetic nerve activity in humans. (1987)

The purpose of this study was to determine the effects of the cold pressor test on sympathetic outflow with direct measurements of nerve traffic in conscious humans and to test the strength of correlation between sympathetic nerve discharge and the changes in arterial pressure, heart rate, and plasma norepinephrine. In 25 healthy subjects, arterial pressure, heart rate, and muscle sympathetic nerve activity were measured with microelectrodes inserted percutaneously into a peroneal muscle nerve fascicle in the leg during immersion of the hand in ice water for 2 minutes. Arterial pressure rose steadily during the first and second minutes of the cold pressor test. Muscle sympathetic activity (burst frequency X amplitude) did not increase in the first 30 seconds of the test but increased from 230 +/- 27 to 386 +/- 52 units (mean +/- SE, p less than 0.05) by the end of the first minute of the test and to 574 +/- 73 (p less than 0.01) during the second minute. In contrast, heart rate increased maximally during the first 30 seconds of the cold pressor test and returned to control during the second minute. The increases in heart rate were abolished by beta-adrenergic blockade. The increases in muscle sympathetic activity during the cold pressor test were correlated with the increases in both mean arterial pressure (r = 0.86, p less than 0.01) and peripheral venous norepinephrine (r = 0.72, p less than 0.05); however, large changes in nerve traffic were associated with small changes in plasma norepinephrine.(ABSTRACT TRUNCATED AT 250 WORDS)
Techniques for inhibiting tumor metastases (1975)

Of the four major biological mechanisms of cancer spread, hematogenous dissemination is perhaps the most significant, as it usually heralds a fatal outcome for the patient. Recent experimental approaches have shown ways of altering the metastatic process and even totally inhibiting it in some animal models. It appears that these models may be applicable to certain human cancers. To prevent hematogenous metastasis formation the process must be inhibited at any one of four levels: 1) growth of the primary; 2) invasion of vessel walls; 3) release of viable tumor cells; or 4) entrapment and growth in distant organs. Judicious handling of the primary can decrease metastasis by minimizing the shedding of tumor cells. New experimental agents prevent the release of tumor cells from the primary by normalizing the blood vessels of the tumor. Warfarin, heparin, and fibrinolytic agents inhibit the entrapment of circulating tumor cells, presumably by their effect on coagulative mechanisms. A better understanding of the benefits of combined approaches to cancer using chemotherapy, irradiation, and immunotherapy, alone and as adjuncts to surgery, offers new opportunity to study methods of controlling metastatic disease.
