A manifold approach to face recognition from low quality video across illumination and pose using implicit super-resolution (2007)

We consider the problem of matching a face in a low resolution query video sequence against a set of higher quality gallery sequences. This problem is of interest in many applications, such as law enforcement. Our main contribution is an extension of the recently proposed Generic Shape-Illumination Manifold (gSIM) framework. Specifically, (i) we show how super-resolution across pose and scale can be achieved implicitly, by off-line learning of subsampling artefacts; (ii) we use this result to propose an extension to the statistical model of the gSIM by compounding it with a hierarchy of subsampling models at multiple scales; and (iii) we describe an extensive empirical evaluation of the method on over 1300 video sequences – we first measure the degradation in performance of the original gSIM algorithm as query sequence resolution is decreased and then show that the proposed extension produces an error reduction in the mean recognition rate of over 50%.
Activation becomes highly organized during long-duration ventricular fibrillation in canine hearts (2010)

Little is known about the three-dimensional (3-D) intramural activation sequences during long-duration ventricular fibrillation (VF), including the role of the subendocardium and its Purkinje fibers (PFs) in long-duration VF maintenance. Our aim was to explore the mechanism of long-duration VF maintenance with 3-D electrical mapping. We recorded 10 min of electrically induced VF in the left ventricular anterior free wall of six 10-kg, open-chest dogs using a 3-D transmural unipolar electrode matrix (9 x 9 x 6, 2-mm spacing) that allowed us to map intramural activation sequences. At 2.5 + or - 1.8 min of VF, although the body surface ECG continued to exhibit a disorganized VF pattern, intramurally a more organized, synchronous activation pattern was first observed [locally synchronized VF (LSVF)]. This pattern occurred one or more times in all dogs and was present 33.4 + or - 31.4% of the time during 5-10 min of VF. As opposed to the preceding changing complex activation sequences of VF, during LSVF, wavefronts were large and highly repeatable near the endocardium, first exciting the endocardium almost simultaneously and then rapidly spreading toward the epicardium with different levels of conduction block en route. During LSVF, PF activations always preceded working myocardium activations near the endocardium. In conclusion, long-duration VF in dogs frequently becomes highly organized in the subendocardium, with activation fronts arising in this region and passing intramurally toward the epicardium, even though the surface ECG continues to exhibit a disorganized pattern. PFs appear to play an important role during this stage of VF.
RNA binding specificity of a<i>Drosophila</i>snRNP protein that shares sequence homology with mammalian U1-A and U2-B’ proteins (1992)

We have characterized a recombinant Drosophila melanogaster RNA binding protein, D25, by virtue of its antigenic relationship to mammalian U1 and U2 small nuclear ribonucleoprotein (U snRNP) proteins. Sequence analysis revealed that D25 bears strong similarity to both the human U1 snRNP-A (U1-A) and U2 snRNP-B" (U2-B") proteins. However, at residues known to be critical for the RNA binding specificities of U1-A and U2-B" D25 sequence is more similar to U2-B". Using direct RNA binding assays D25 selected U1 RNA from either HeLa or Drosophila Kc cell total RNA. Furthermore, D25 bound U1 RNA when transfected into mammalian cells. Thus, D25 appears to be a Drosophila homolog of the mammalian U1-A protein, despite its sequence similarity to U2-B".
A Pyridine‐Containing Anthracene Derivative with High Electron and Hole Mobilities for Highly Efficient and Stable Fluorescent Organic Light‐Emitting Diodes (2011)

Abstract A pyridine‐containing anthracene derivative, 9,10‐bis(3‐(pyridin‐3‐yl)phenyl)anthracene (DPyPA), which comprehensively outperforms the widely used electron‐transport material (ETM), tris(8‐quinolinolato) aluminum (Alq 3 ), is synthesized. DPyPA exhibits ambipolar transport properties, with both electron and hole mobilities of around 10 −3 cm −2 V −1 s −1 ; about two orders of magnitude higher than that of Alq 3 . The nitrogen atom in the pyridine ring of DPyPA coordinates to lithium cations, which leads to efficient electron injection when LiF/Al is used as the cathode. Electrochemical measurements demonstrate that both the cations and anions of DPyPA are stable, which may improve the stability of devices based on DPyPA. Red‐emitting, green‐emitting, and blue‐emitting fluorescent organic light emitting diodes with DPyPA as the ETM display lower turn‐on voltages, higher efficiencies, and stronger luminance than the devices with Alq 3 as the ETM. The power efficiencies of the devices based on DPyPA are greater by 80–140% relative to those of the Alq 3 ‐based devices. The improved performance of these devices is attributed to the increased carrier balance. In addition, the device employing DPyPA as the ETM possesses excellent stability: the half‐life of the DPyPA‐based device is 67 000 h—seven times longer than that of the Alq 3 ‐based device—for an initial luminance of 5000 cd m −2 .
Parallel hierarchical global illumination (2002)

This paper presents an algorithm that solves the Rendering Equation to any desired accuracy, and can be run in parallel on distributed memory or shared memory computer systems with excellent scaling properties. It appears superior in both speed and physical correctness to recent published methods involving bidirectional ray tracing or hybrid treatments of diffuse and specular surfaces. Like "progressive radiosity" methods, it dynamically refines the geometry decomposition where required, but does so without the excessive storage requirements for "ray histories.".
Hepatocyte growth factor in renal regeneration, renal disease and potential therapeutics (2000)

Hepatocyte growth factor (HGF) has mitogenic, motogenic, morphogenic, and anti-apoptotic activities on renal cells and is a potential renotropin for renal protection and repair. In chronic renal failure/fibrosis, HGF in the kidney declines in a reciprocal manner to the increase in transforming growth factor-beta (TGF-beta). Neutralization of HGF by the antibody leads to acceleration of renal failure/fibrosis while HGF administration leads to remarkable attenuation, thus indicating the importance of HGF versus TGF-beta counterbalance in both pathogenesis and therapeutics in cases of chronic renal failure. HGF is being strongly considered for potential treatment of acute and chronic renal failure.
Optical time domain reflectometry in a single-mode fiber (1981)

This paper describes the theoretical and experimental study of an optical time domain reflectometry (OTDR) in a single-mode fiber. The maximum measurable distance by the OTDR is theoretically studied. In the experiment, the cylindrical lens attached to the laser diode, the low-loss and low-crosstalk directional coupler, and the digital averaging technique combined enabled us to measure a break in a single-mode fiber up to 17 km in length. This paper also describes the application of the OTDR to loss measurement of a single-mode fiber.
Influence of CoQ10 on Autonomic Nervous Activity and Energy Metabolism during Exercise in Healthy Subjects (2008)

These results suggested that CoQ10 may increase fat oxidation with augmented autonomic nervous activity during low intensity exercise.
Yet another multiplier architecture (2002)

The VLSI multiplier architecture discussed makes advances over previous architectures in terms of layout density and flexibility in making speed/size tradeoffs. This multiplier design and a ripple adder were used in LSI Logic's L64814 floating point processor for use in Sun Microsystem's SPARC system architecture. The novel architectural design yielded a 56-by-56, 30 ns, nonpipelined, 4100 transistor/mm/sup 2/, semi-custom, multiplier-accumulator. However, the architectural concept is general and flexible enough to accommodate any size multiplier and allow tradeoffs between a given multiplier's area and speed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Corps des jeunes pour la conservation : emploi et environnement (2006)

Engaging young people in environmental service projects is an innovative way of achieving several priority objectives through one single intervention. A well-designed Youth Conservation Corps (YCC) can provide youth with skills that enhance their employability, protect or restore critical ecosystems, and create a pro-conservation citizenry. This issue of Youth Development Notes profiles Youth Conservation Corps interventions in developed and developing country contexts and offers some guiding principles on effective program design. The paper concludes that activities for the environment can safeguard and restore vulnerable habitat, and by doing so, insure the provision of ecosystem services that are tied directly to the welfare of both urban and rural populations, such as improved water quality and food supply. Through actions such as planting trees, restoring coastal mangroves, building trails in national parks, removing invasive plant species, and training junior park wardens, the YCC harnesses the energy of today's youth toward the health of tomorrow's planet.
MARS: A multi-aspect Recommender system for Point-of-Interest (2015)

With the pervasive use of GPS-enabled smart phones, location-based services, e.g., Location Based Social Networking (LBSN) have emerged . Point-of-Interests (POIs) Recommendation, as a typical component in LBSN, provides additional values to both customers and merchants in terms of user experience and business turnover. Existing POI recommendation systems mainly adopt Collaborative Filtering (CF), which only exploits user given ratings (i.e., user overall evaluation) about a merchant while regardless of the user preference difference across multiple aspects, which exists commonly in real scenarios. Meanwhile, besides ratings, most LBSNs also provide the review function to allow customers to give their opinions when dealing with merchants, which is often overlooked in these recommender systems. In this demo, we present MARS, a novel POI recommender system based on multi-aspect user preference learning from reviews by using utility theory. We first introduce the organization of our system, and then show how the user preferences across multiple aspects are integrated into our system alongside several case studies of mining user preference and POI recommendations.
Ga substitution effect on magnetic and magnetostrictive properties of TbFe2 compounds (1994)

In the present paper magnetic and magnetostrictive properties of Tb(Fe1−xGax)2 (x=0–0.2) compounds were investigated. It was found that the iron moment of the compounds does not seem to vary much for x≤0.12. The Curie temperatures of the compounds decrease continuously by substituting Ga for Fe, which was attributed to the decrease of the R-T coupling strength due to Ga substitution. The intersublattice coupling constant JRFe was evaluated by molecular field model. The decrease of JRFe with increasing Ga content was found and related to the decrease of the number of the Tb-Fe interaction pairs when replacing Fe with Ga. By using an x-ray diffractometer the samples were step scanned with Cu radiation at a higher Bragg angle 2θ ranging from 71° to 74° to study the cubic (440) reflection. The splitting of (440) reflection for X≤1.2 was clearly seen and the easy direction magnetostriction λ111 of the compounds was calculated. It was found that λ111 decreases with increasing Ga content. This was attributed to the decrease of magnetic properties of the compounds. The polycrystal magnetostriction λs of the compounds has also been studied.
두둑을 재활용한 한국형 무경운 농업 II. 시설 무경운 토양의 물리적 특성: 입단과 용적밀도 및 삼상변화 (2016)

This study was carried out to investigate the effect of no-tillage on sequential cropping supported from recycling of first crop ridge on the productivity of crop and physical properties of soil under green house condition. This study is a part of “No-tillage agriculture of Korea-type on recycled ridge”. From results for distribution of soil particle size with time process after tillage, soil particles were composed with granular structure in both tillage and no-tillage. No-tillage soil in distribution of above 2 mm soil particle increased at top soil and subsoil compared with tillage soil. Tillage and one year of no-tillage soil were not a significant difference at above 0.25 mm~below 0.5 mm, above 0.5 mm~below 1.0 mm, and above 1.0 mm of water-stable aggregate. Two years of no-tillage soil was significantly increased by 8.2%, 4.5%, and 1.7% at above 0.25 mm~below 0.5 mm, above 0.5 mm~below 1.0 mm, and above 1.0 mm of water-stable aggregate, respectively, compared with one year of no-tillage. Bulk density of top soil was 1.10 MG m3 at tillage and 1.30 MG m3 at one year of no-tillage. Bulk density of top soil was 1.14 MG m3 at two years and 1.03 MG m3 at three years of no-tillage, respectively. Bulk density of subsoil was a similar tendency. Solid phase ratio in top soil and subsoil was increased at one year of no-tillage compared with tillage soil, while soil phase ratio decreased at two and three years of no-tillage. Pore space ratio in tillage top soil (58.5%) was decreased by 8.5% at compared with no-tillage soil (51.0%). Pore space ratio was 56.9% and 61.2% at two and three years of no-tillage soil, respectively. Subsoil was a similar tendency. Gaseous phase ratio was decreased at one year of no-tillage soil, and increased at two and three years of no-tillage soil compared with tillage soil. Liquid phase ratio in top soil was increased at one year of no-tillage (28.3%), and decreased at two years (23.4%) and at three years (18.3 %) of no-tillage soil compared with tillage soil (24.2%). Subsoil was a similar tendency. Liquid phase ratio in subsoil was increased than top soil.
Objective-driven monitoring for broadband networks (1996)

An approach to sensor configuration, installation, and activation for real-time monitoring of broadband networks for performance management is presented. An objective-driven measurement strategy for establishing the dynamic and statistical databases of the network is described. Objective driven monitoring allows the activation of sensors for data collection and abstraction based on a set of objectives. The objectives are derived from the quality of service requirements for real-time traffic control and operator submitted queries. The methodology of objective-driven monitoring for selective activation of sensors is implemented as a set of rules in the knowledge base of the monitor.
Racial/Ethnic Disparities in Household Debt Repayment (2009)

This study proposes to gain insight into which key factors influence household debt repayment; whether these key factors differ across racial/ethnic groups; and whether these factors result in racial/ethnic variance.In particular, this study aims first to: (1) account for household characteristics related to repayment delinquency, (2) examine whether race and ethnicity are related to debt payment problems, even controlling financial events that might cause a decrease or disruption in the flow of periodic household income, financial buffers available in emergency and any other demographic variable and (3) examine how the effects of key factors differ across race and ethnicity.Table 5.
Towards the computational perception of action (2002)

Understanding observations of interacting objects requires one to reason about qualitative scene dynamics. For example, on observing a hand lifting a can, we may infer that an 'active' hand is applying an upwards force (by grasping) to lift a 'passive' can. Previously we presented a system that infers qualitative scene dynamics from the instantaneous motion of objects. However; since that analysis only considered single frames in isolation, there were often multiple interpretations for each frame. In this work we show how the dynamic information inferred at each frame can be integrated over time to reduce ambiguity. Our approach to integrating information is to extend our representation to describe objects by a set of properties or capabilities that are assumed to persist over time. Given this extended representation we find interpretations that require the smallest set(s) of properties over the whole image sequence.

Diagnosis and molecular basis of mitochondrial respiratory chain disorders: Exome sequencing for disease gene identification (2014)

Mitochondrial disorders have the highest incidence among congenital metabolic diseases, and are thought to occur at a rate of 1 in 5000 births. About 25% of the diseases diagnosed as mitochondrial disorders in the field of pediatrics have mitochondrial DNA abnormalities, while the rest occur due to defects in genes encoded in the nucleus. The most important function of the mitochondria is biosynthesis of ATP. Mitochondrial disorders are nearly synonymous with mitochondrial respiratory chain disorder, as respiratory chain complexes serve a central role in ATP biosynthesis. By next-generation sequencing of the exome, we analyzed 104 patients with mitochondrial respiratory chain disorders. The results of analysis to date were 18 patients with novel variants in genes previously reported to be disease-causing, and 27 patients with mutations in genes suggested to be associated in some way with mitochondria, and it is likely that they are new disease-causing genes in mitochondrial disorders. This article is part of a Special Issue entitled Frontiers of Mitochondrial Research.
Information and inference as combinedcognitive process. (2004)

El concepto de inferencia es bastante oscuro y complejo, especialmente cuando se lo vincula con el de información y su procesamiento; ambos están estrechamente imbricados. Las inferencias pueden ser vistas como medio para acceder a distintas categorías de conceptos, relacionarlos y generar nuevas categorizaciones y conceptos. Las inferencias facilitan la construcción y la comprensión del discurso. El discurso tiene una estructura inferencial dinámica que permite formaciones y transformaciones de significados. Uno de los roles claves de las inferencias es llenar vacíos o lagunas de la información disponible, logrando representaciones que dan mayor continuidad y coherencia a los argumentos. Las inferencias construyen y completan la información textual y contextual faltante al mensaje fragmentario. El empleo racional y avanzado de la información descansa sobre implicaciones que sólo pueden dar esos recursos inferenciales. Existe un trasfondo inferencial en toda búsqueda atinada y pertinente de información y su ulterior procesamiento, por lo cual postulamos una interacción dinámica entre inferencias implícitas y explícitas de toda información que permiten anticipar aspectos imprevisibles de creatividad humana.
Inducible NorA-mediated multidrug resistance in Staphylococcus aureus (1995)

The NorA protein of Staphylococcus aureus mediates the active efflux of hydrophilic fluoroquinolones from the cell, conferring low-level resistance upon the organism. The protein also is capable of transporting additional structurally diverse compounds, indicating that it has a broad substrate specificity. Increased transcription of the norA gene, leading to a greater quantity of the NorA protein within the cytoplasmic membrane, is felt to be the mechanism by which strains possessing such changes resist fluoroquinolones. S. aureus SA-1199 and its in vivo-selected derivative SA-1199B are fluoroquinolone-susceptible and -resistant isolates, respectively; SA-1199B resists hydrophilic fluoroquinolones via a NorA-mediated mediated mechanism in a constitutive manner. SA-1199-3 is an in vitro-produced derivative of SA-1199 in which NorA-mediated multidrug resistance is expressed inducibly. Compared with organisms exposed to subinhibitory concentrations of a NorA substrate for the first time, preexposure of SA-1199-3 to such a compound followed by growth in the presence of that substrate results in the elimination of a 2- to 6-h period of organism killing that occurs prior to the onset of logarithmic growth. The uptake of radiolabeled fluoroquinolone is markedly reduced by preexposure of SA-1199-3 to NorA substrates: such prior exposure also results in a dramatic increase in RNa transcripts that hybridize with a norA probe. Preexposure of SA-1199 and SA-1199B to such substrates results in small increases or no increases in these transcripts. No sequence differences between SA-1199 and SA-1199-3 within the norA gene or flanking DNA were found. It appears likely that the regulation of norA in SA-1193, which may be effected by one or more genetic loci outside the norA region of the chromosome, differs from that of SA-1199 and SA-1199B.
