Face based image navigation and search (2009)

People are often the most important subjects in photos, and the ability of finding photos of a particular person easily and quickly in an image collection is highly desired. In this paper, we present a face clustering system which automatically groups photos into clusters, with each cluster containing photos of the same person. This is done based on an advanced face recognition engine and a semi-supervised clustering approach. The system achieved good clustering accuracy when tested on different image sets and by different users. Moreover, features such as adding new images, face cluster navigation and face based image retrieval are added that greatly improve the usability of the system. It also facilitates efficient manual manipulations of clustering results. On top of this technology, image navigation systems have been built, including the "face bubble" visualization which provides one-glance view of a photo collection, and shows the relations among people.
Insect Antifeedant Activity of Tetranortriterpenoids from the Rutales. A Perusal of Structural Relations (2002)

Structure-related insect antifeedant relationship of 56 limonoids (both natural and modified) from the plants belonging to the order Rutales was attempted considering substitution patterns, oxidation states, and hydrophobicity, as well as distant geometry derived through conformational analysis on molecular modeling. Orientation of the furan and hydroxylation at specific carbon sites have been shown to influence the antifeedancy against the fall armyworm, Spodoptera litura.
Twin-core fibre erbium-doped channel equalizer (1995)

A passive channel equalizer using a twin-core EDFA is studied in detail. It relies on the spatial separation of the different channels provided by the twin-core geometry and the power-dependent differential gain saturation given by the erbium ions. The amount of channel equalization depends on the fiber geometry parameters, as well as the optical parameters and relative channel power. In the two-channel case, gain saturation limits the useful channel input powers into the range of ~ -20 dBm to -0 dBm. Channel equalization rates in excess of -0.4 dB per dB of input-power imbalance are predicted. When used in cascade, twin-core EDFAs are shown to provide not only efficient channel-power stabilization, but also self-healing against additional channel losses.
Preparation and characterisation of electrospun composite nanofibre polyvinyl alcohol/ nanofibrillated cellulose isolated from oil palm empty fruit bunches (2020)

Composite nanofibre polyvinyl alcohol (PVOH) was prepared in this work reinforced with nanofibrillated cellulose (NFC) using an electrospinning technique. NFC was isolated from oil palm empty fruit bunches (OPEFB) by steam explosion method followed by acid hydrolysis. A 12 wt% PVOH solution in distilled water was prepared under constant reflux at 80 ºC for 5 h. Several concentrations of NFC were added to the polymer solution of 2.5, 5.0, and 7.5 wt%. The nano-dimension of NFC was analysed using transmission electron microscopy (TEM). The morphology of electrospun nanofibre was characterised using scanning electron microscopy (SEM). The morphology of PVOH nanofibre was smooth and uniform without beads. The presence of NFC in the PVOH nanofibre decreased the diameter. The morphology of PVOH/NFC nanofibre at a concentration of NFC 2.5% was fairly uniform with good quality. However, the preparation of PVOH/NFC nanofibre at concentrations of NFC 5.0% and 7.5% resulted in elliptical beads. The crystallinity of NFC and electrospinning nanofibre was investigated using X-ray diffraction (XRD). In addition, the thermal properties of the samples were analysed using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results showed that NFC improved the thermal stability of electrospun PVOH nanofibre.
The status of the species Lactobacillus casei (Orla-Jensen 1916) Hansen and Lessel 1971 and Lactobacillus paracasei Collins et al. 1989. Request for an opinion. (2002)

On the basis of considerable published evidence, it is concluded that the species Lactobacillus casei is not correctly represented by the strain actually designated as the type strain ATCC 393. It is proposed that the Judicial Commission consider: (1) that ATCC 393T is scientifically unsuitable as the type strain of Lactobacillus casei and should be reclassified as Lactobacillus zeae; (2) that Lactobacillus casei ATCC 334 and Lactobacillus paracasei strains are members of the same taxon and therefore can be united within the name Lactobacillus casei (Rules 42 and 23a), the name Lactobacillus paracasei being rejected; and (3) designating ATCC 334 as the neotype strain for the species
Single Periocular Injection of Celecoxib-PLGA Microparticles Inhibits Diabetes-Induced Elevations in Retinal PGE<sub>2</sub>, VEGF, and Vascular Leakage (2006)

Nanomolar concentrations of celecoxib can inhibit VEGF mRNA and protein expression from ARPE-19 cells. Periocular celecoxib microparticles are useful sustained drug delivery systems for inhibiting diabetes-induced elevations in PGE2, VEGF, and blood-retinal barrier leakage. The periocular celecoxib-PLGA microparticles are safe and do not cause any damage to the retina.
The <i>Hox11</i> gene is essential for cell survival during spleen development (1995)

The HOX11 homeobox gene was identified via the translocation t(10;14) in T cell leukaemia. To determine the function of this gene in mice, null mutations were made using homologous recombination in ES cells to incorporate lacZ into the hox11 transcription unit. Production of beta-galactosidase from the recombinant hox11 allele in +/- mutants allowed identification of sites of hox11 expression which included the developing spleen. Newborn hox11 -/- mice exhibit asplenia. Spleen formation commences normally at E11.5 in hox11 -/- mutant embryos but the spleen anlage undergoes rapid and complete resorption between E12.5 and E13.5. Dying spleen cells exhibit molecular features of apoptosis, suggesting that programmed cell death is initiated at this stage of organ development in the absence of hox11 protein. Thus hox11 is not required to initiate spleen development but is essential for the survival of splenic precursors during organogenesis. This function for hox11 suggests that enhanced cell survival may result from the t(10;14) which activates HOX11 in T cell leukaemias, further strengthening the association between oncogene-induced cell survival and tumorigenesis.
Use of a multiparametric panel to target subpopulations in a heterogeneous solid tumor model for improved analytical accuracy (1995)

The exclusion of non-tumor and dead cells from the analysis of live tumor cells can significantly improve the accuracy of prognostic indicators such as proliferative and DNA indexes. To target live breast tumor cells in a heterogeneous breast tumor model, we have designed a panel consisting of the DNA-specific dye DAPI and epithelial tissue-specific (cytokeratin), tumor-associated (MC5), proliferation-associated (proliferating cell nuclear antigen), and viability-associated (tubulin) markers. The breast tumor model consisted of a mixture of equal numbers of live and dead MDA-MB-175-VII (breast tumor) cells, live CEM (leukemic) cells, and live peripheral blood mononuclear cells. Targeting the live MDA cells in the mixture by gating on tubulin, cytokeratin, and MC5 resulted in a sevenfold increase in PCNA positivity (from 3% ungated to 22.3%), a 60% decrease in the %S-phase fraction (from 37.2% ungated to 15%), and elimination of extraneous hypodiploid and diploid components, enriching the tetraploid MDAs. These results are consistent with those obtained from unmixed live MDA cells. The combined utilization of this panel and "cumulative" electronic gating of the targeted population increases the number of relevant parameters that can be analyzed per sample and the accuracy of the resultant data.
The Serum Level of IL-1B Correlates with the Activity of Chronic Pulmonary Aspergillosis (2018)

Higher level of serum IL-1B is associated with more severe cavitary and aspergilloma lesions, which are indicative of more active CPA. In addition, IL-1B level reduced accordingly after lesion resection. Measuring IL-1B level therefore could be served as a convenient method to monitor the activity of CPA and be a potential predictive/prognostic marker for treatment response.
A new monoclonal antibody for detection of EGF‐receptors in western blots and paraffin‐embedded tissue sections (1992)

The prognostic significance of the epidermal growth factor receptor status (EGF-R-status) for certain human tumors requires the development of antibodies useful for clinical application. We used purified receptor preparations to generate monoclonal antibodies immunoreactive with the EGF-R purified from placenta membranes and A431 tumors. Four of the hybridomas contained antibodies (R2, R3, R5, and R9) which recognized both antigens. Antibody R3 was shown to display the following properties: it binds with a KD value of about 10(-9)-10(-10) M to the receptor, a half maximal inhibition of EGF-binding is achieved at 5 x 10(-8) M, and in Western blots of cell membranes R3 specifically detects the EGF-R at 0.1 micrograms/ml. R3 inhibits EGF-dependent clonogenic growth of NRK cells and completely blocks EGF stimulated autophosphorylation of the receptor. Moreover, R3 also detects EGF-R in paraffin-embedded tissue sections taken from human salivary gland, term placenta, and adult skin and mammary carcinomas. Thus, R3 can be used in retrospective diagnostic clinical studies and might help to develop new immunotherapeutic intervention.
Effects of Recombinant Bovine Somatotropin on Milk Production, Body Composition, and Physiological Parameters (1988)

Twenty-eight multiparous Holstein cows were utilized to determine effects of long-term administration of recombinant bovine somatotropin on lactational performance, body condition, body composition, hormones, blood constituents, and physiological parameters. Treatments were 0 (control), 10.3, 20.6, and 41.2 mg recombinant bovine somatotropin administered daily as subcutaneous injections beginning 4 to 5 wk postpartum and continuing for 38 wk. A total mixed diet of 28% corn silage, 22% alfalfa hay cubes, and 50% corn-soybean meal-based grain mixture was fed. Fat-corrected milk yields were increased 12 to 25% for cows treated with somatotropin as compared with controls (29.9 kg/d). Milk composition was similar among treatments. Cows receiving somatotropin consumed 4 to 10% more feed and were 11 to 17% more efficient than controls for conversion of feed to milk. Body weight changes were not significantly different among treatments, but cows receiving somatotropin gained 4 to 10% less weight than controls. Body fat (kg) of cows receiving 20.6 and 41.2 mg/d was less than that of cows receiving 10.3 mg/d or no somatotropin. Estimated weights of body protein and mineral, most blood constituents, respiratory rates, and body temperature were not affected by somatotropin administration. Plasma fatty acids were elevated and hematocrit values were reduced. Plasma insulin, serum somatotropin, and heart rate increased concurrently with somatotropin administration.
GraphSC: Parallel Secure Computation Made Easy (2015)

We propose introducing modern parallel programming paradigms to secure computation, enabling their secure execution on large datasets. To address this challenge, we present Graph SC, a framework that (i) provides a programming paradigm that allows non-cryptography experts to write secure code, (ii) brings parallelism to such secure implementations, and (iii) meets the need for obliviousness, thereby not leaking any private information. Using Graph SC, developers can efficiently implement an oblivious version of graph-based algorithms (including sophisticated data mining and machine learning algorithms) that execute in parallel with minimal communication overhead. Importantly, our secure version of graph-based algorithms incurs a small logarithmic overhead in comparison with the non-secure parallel version. We build Graph SC and demonstrate, using several algorithms as examples, that secure computation can be brought into the realm of practicality for big data analysis. Our secure matrix factorization implementation can process 1 million ratings in 13 hours, which is a multiple order-of-magnitude improvement over the only other existing attempt, which requires 3 hours to process 16K ratings.
Pseudoequilibrium Model Based Estimator of Matte Grade in a Copper Smelter (1997)

A smelter model has been developed as the basis for an inferential matte grade estimator for an industrial copper smelter. This model couples dynamic mass balances on each species with equilibrium relationships for each component to form a system of differential and algebraic equations. An extended Kalman filter (EKF) based on the dynamic model was applied to track variations in feed composition and enhance the model performance for estimating matte grade. For simulated plant data, the extended Kalman filter tracked feed composition disturbances very well. The effect of the frequency of matte grade measurements on the accuracy of the grade estimates was studied. Off gas composition measurements were also used to infer matte grade and improve the estimator performance. When these secondary measurements were used in conjunction with the matte grade measurements in the EKF algorithm, the estimator produced the smallest error between the estimate and the plant.
Comparative studies on the effect of butylhydroxytoluene and ethoxyquin on the antioxidative and oxidative balance in broilers (1994)

Zusammenfassung Der Einfluß von Butylhydroxytoluol und Ethoxyquin auf einige antioxidative und oxidative Parameter beim Broiler In zwei Versuchen wurde an weibliche Broilerküken über die Dauer von 6 Wochen ein kommerzielles bei 85°C expandiertes Broilerfutter verabreicht. Dem Futter waren entweder 150 ppm Butylhydroxytoluol (BHT), 150 ppm Ethoxyquin (EQ), einc Mischung von BHT und EQ (jeweils 75 ppm) oder keines der genannten Antioxidantien zugesetzt. Die Zahl der Versuchstiere betrug in den beiden Versuchen 60 bzw. 48 Tiere. Im zweiten Versuch wurde die Hälfte der Tiere bereits nach 3 Wochen geschlachtet. Die zu Anfang des Versuchs im Futter gemessenen Konzentrationen der synthetischen Antioxidantien erwiesen sich niedriger als die dem Futter zugegebenen Konzentrationen. Alle im Versuch eingesetzten Antioxidantien zeigten im Hinblick auf die Peroxidbildung im Futter eine vorbeugende Wirkung. Hinsichtlich der Versuchsparameter Gewichtszunahme, Futterverwertung, Hämatokrit, Hämolyseeigenschaften der Erythrozyten, Plasmaaktivitäten der Enzyme Glutamat‐Oxalacetat‐Transaminase (GOT), Creatin‐Kinase (CK) und Glutathion‐Peroxidase (GSH‐Px) sowie Natriumkonzentration im Plasma konnten keine Unterschiede zwischen den eingesetzten Antioxidantien festgestellt werden. Das Gleiche galt für die Vitamin E Konzentrationen im Muskel‐ und Lebergewebe sowie für das Calciumakkumulationvermögen des sarkoplasmatischen Retikulums. Broiler, denen keine synthetischen Antioxidantien im Futter verabreicht wurden, zeigten eine höhere K+‐Konzentration im Blutplasma. Die Antioxidantienmischung (BHT und EQ) führte nach 6‐wöchiger Versuchsdauer bei den Tieren zu einer Steigerung der γ‐Tocopherolkonzentration sowie zu einer Erhöhung der relativen Lebergewichte. Nach 3 Wochen lag die Aktivität der Non‐Se‐GSH‐Px im Lebereytosol bei den Tieren dieser Gruppe deutlich höher. Gemessen an der Gesamtaktivatät der GSH‐Px im Lebercytosol lag der Anteil der Non‐Se‐GSH‐Px in allen Gruppen nach 6 Wochen höher als nach 3 Wochen. Broiler, denen BHT verabreicht wurde, wiesen im Vergleich zu Tieren, die EQ erhielten, ein besseres Wasserbindungsverrnögen der Skelettmuskulatur (Schenkel‐und Brustmuskel) auf.

Substitution and deletion mutations induced by 2-hydroxyadenine in Escherichia coli: effects of sequence contexts in leading and lagging strands (1997)

To evaluate the mutation frequency and the mutation spectrum of 2-hydroxyadenine (2-OH-Ade), an oxidative DNA lesion, the modified base was site-specifically incorporated into a unique restriction enzyme site (SalI, GTCGA*C or AflII, CTTA*AG where A* represents 2-OH-Ade) in single- and double-stranded vectors. The 2-OH-Ade residues were introduced into (+)- and (-)-strands of the double-stranded vectors and into the (+)-strand of single-stranded vectors. When the vectors were transfected intoEscherichia coli, the modified base showed little to no cytotoxicity. The mutation frequencies of 2-OH-Ade in the SalI and AflII sites were approximately 0.8 and 0.07%, respectively, with double-stranded (+)-vectors. An increase in the mutation frequencies was not observed with single-stranded vectors. When incorporated into the (-)-strand, the mutation frequencies of 2-OH-Ade in the SalI and AflII sites were approximately 0.3 and 0.1%, respectively. The mutations observed most frequently were -1 deletions at both positions, in the case of the (+)-strand. On the other hand, we observed that 2-OH-Ade in the (-)-strand induced A-->G and A-->T substitutions. These results indicate that 2-OH-Ade residues in DNA induce substitution and deletion mutations without blocking replication inE.coli.
A Review of Methods Used to Reinforce Polymethyl Methacrylate Resin (1995)

Various methods to reinforce acrylic denture base material have been used to repair fractures in complete dentures. Metal wires and plates have been tested as reinforcement of polymethyl methacrylate (PMMA) resin. The contributions of the studies conducted on this biphase composite system are discussed in this review article. The literature has reported that even thin metal wires incorporated into the PMMA matrix increased the transverse strength of the PMMA construction. Metal mesh inserted into PMMA resin had negligible effects on the transverse strength of the restoration. macroscopic retention of the metal strengtheners to the PMMA had only a minor effect on the strength in contrast to microscopic retention, which showed a more marked effect. Chemical bonding between the PMMA and metal reinforcer enhanced the strength of the prosthesis with some exceptions.
Studies of atomic and molecular fluorine reactions on silicon surfaces (1986)

X-ray photoelectron spectroscopy (XPS) and an ultrahigh vacuum compatible microwave discharge effusive beam source have been used to study the reactions of atomic and molecular fluorine on Si(111) surfaces. Fluorine uptake and changes in binding energy and peak shape for the Si 2p and F 1s XPS peaks have been measured as functions of fluorine exposure. The results indicate that molecular fluorine is dissociatively chemisorbed to form an SiF2-like surface species. This reaction saturates at approximately one monolayer surface coverage. In contrast, atomic fluorine uptake extends well beyond the monolayer regime to include several Si layers. Additionally, as the uptake increases, the reaction product becomes SiF4-like. These findings are compared with previously reported results for XeF2 adsorption.
Raman-gain estimates for high-gain optical fibers (1987)

The amplification of light signals by the mechanism of stimulated Raman scattering is discussed, with specific reference to certain heavy-metal germanate and arsenate glasses with Raman-gain-coefficients G of up to 20 times that of fused silica. Calculations are presented of the intrinsic scattering losses from Rayleigh, Brillouin, and spontaneous Raman sources for these compositions which, when combined with the measured G values, determine the potential signal-amplification capabilities as a function of pump power and fiber length L. Direct comparisons are made with an equivalent calculation for an ideally pure germania fiber. The results hinge sensitively upon the degree to which concentration fluctuations (leading to concentration-scattering Rayleigh loss) are intrinsic in the multicomponent high-G glass compositions. In spite of this, some compositions are located which can outperform pure germania fibers even in the presence of signficant concentration-scattering loss. This is particularly so for high pump powers and short fiber lengths L&lt;2 km.
Synthesis, Structure−Activity Relationship, and Receptor Pharmacology of a New Series of Quinoline Derivatives Acting as Selective, Noncompetitive mGlu1 Antagonists (2005)

We describe the discovery and the structure-activity relationship of a new series of quinoline derivatives acting as selective and highly potent noncompetitive mGlu1 antagonists. We first identified cis-10 as a fairly potent mGlu1 antagonist (IC(50) = 20 nM) in a cell-based signal transduction assay on the rat mGlu1 receptor expressed in CHO-K1 cells, and then we were able to design and synthesize highly potent compounds on both rat and human mGlu1 receptors as exemplified by compound cis-64a, which has an antagonist potency of 0.5 nM for the human mGlu1 receptor. We briefly present and discuss the in vitro metabolic stability of the compounds in human liver microsomes. We finally report the pharmacokinetic properties of our lead compound cis-64a.
Simple and Reliable Fabrication of Bioinspired Mushroom-Shaped Micropillars with Precisely Controlled Tip Geometries (2016)

We present a simple yet scalable method with detailed process protocols for fabricating dry adhesives with mushroom-shaped micropillars of controlled tip geometries. The method involves using photo-lithography with a bilayer stack combining SU-8 and lift-off resist, and subsequent replica molding process. This approach utilizes widely used and commercially available materials and can thus be used to generate mushroom-shaped micropillars with precisely controlled tip diameters and thicknesses in a simple, reproducible, and cost-effective manner. The fabricated mushroom-shaped micropillar arrays exhibited highly different tendencies in adhesion strength and repeatability depending on tip geometries, such as tip diameter and thickness, thereby demonstrating the importance of precise tunability of tip geometry of micropillars. The fabricated dry adhesives with optimized tip geometries not only exhibited strong pull-off strength of up to ∼34.8 N cm(-2) on the Si surface but also showed high durability. By contrast, dry adhesives with nonoptimized tips displayed low pull-off strength of ∼3.6 N cm(-2) and poor durability.
Foldable multifunctional planar antenna array (2012)

In this paper, a novel foldable multifunctional planar antenna array is proposed. It provides two modes; diversity and directivity modes. Each mode is switched by folding and unfolding the proposed antenna array. For the diversity mode, four antenna elements are placed for MIMO applications. When the antenna array is folded, its function is changed to the directivity mode and it works as a planar Yagi-Uda antenna. The simulation and measurement results are shown in order to demonstrate two modes are properly working at 2.4 GHz.
Low serum cholesterol concentration and short term mortality from injuries in men and women. (1992)

Together with observations from intervention trials the findings support the existence of a relation between serum cholesterol concentration and suicide. The causality of such a relation is, however, not resolved.
