Close the loop: Joint blind image restoration and recognition with sparse representation prior (2011)

Most previous visual recognition systems simply assume ideal inputs without real-world degradations, such as low resolution, motion blur and out-of-focus blur. In presence of such unknown degradations, the conventional approach first resorts to blind image restoration and then feeds the restored image into a classifier. Treating restoration and recognition separately, such a straightforward approach, however, suffers greatly from the defective output of the ill-posed blind image restoration. In this paper, we present a joint blind image restoration and recognition method based on the sparse representation prior to handle the challenging problem of face recognition from low-quality images, where the degradation model is realistic and totally unknown. The sparse representation prior states that the degraded input image, if correctly restored, will have a good sparse representation in terms of the training set, which indicates the identity of the test image. The proposed algorithm achieves simultaneous restoration and recognition by iteratively solving the blind image restoration in pursuit of the sparest representation for recognition. Based on such a sparse representation prior, we demonstrate that the image restoration task and the recognition task can benefit greatly from each other. Extensive experiments on face datasets under various degradations are carried out and the results of our joint model shows significant improvements over conventional methods of treating the two tasks independently.
Cotinine reduces depressive-like behavior and hippocampal vascular endothelial growth factor downregulation after forced swim stress in mice. (2014)

Cotinine, the predominant metabolite of nicotine, appears to act as an antidepressant. We have previously shown that cotinine reduced immobile postures in Porsolt's forced swim (FS) and tail suspension tests while preserving the synaptic density in the hippocampus as well as prefrontal and entorhinal cortices of mice subjected to chronic restraint stress. In this study, we investigated the effect of daily oral cotinine (5 mg/kg) on depressive-like behavior induced by repeated, FS stress for 6 consecutive days in adult, male C57BL/6J mice. The results support our previous report that cotinine administration reduces depressive-like behavior in mice subjected or not to high salience stress. In addition, cotinine enhanced the expression of the vascular endothelial growth factor (VEGF) in the hippocampus of mice subjected to repetitive FS stress. Altogether, the results suggest that cotinine may be an effective antidepressant positively influencing mood through a mechanism involving the preservation of brain homeostasis and the expression of critical growth factors such as VEGF.

Effects of Glycerol and Moisture Gradient on Thermomechanical Properties of White Bread (2001)

The thermomechanical properties of breadcrumb were investigated using dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC). The main transition (T(1), near 0 degrees C) shifted to lower temperature with added glycerol due to freezing point depression. The low-temperature transition (T(3), approximately -50 degrees C), found only in high-glycerol (8.8%) bread, suggested that of excess or phase-separated glycerol. The high-temperature transition (T(2), 60-85 degrees C) appeared only in aged breadcrumbs; its temperature range was correlated well with the amylopectin melting transition (DSC) but its tan delta amplitude did not correlate well with the amylopectin melting enthalpy (r(2) = 0.72). On the other hand, the change of E' ' (viscous behavior) suggested that T(2) might be related to the change in the amorphous region. Domain-to-domain (amorphous) and crumb-to-crust moisture migrations are two critical phenomenological changes associated with aging and could lead to significant local dehydration of some amorphous regions contributing to mechanical firming during storage.
Anomalous leakage current in LPCVD PolySilicon MOSFET's (1985)

The anomalous leakage current I <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</inf> in LPCVD polysilicon MOSFET's is attributed to field emission via grain-boundary traps in the (front) surface depletion region at the drain, and an analytic model that describes the strong dependences of I <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</inf> on the gate and drain voltages is developed.

Comparison of Motor and Sensory Response of InterStim® for Overactive Bladder Syndrome (2013)

Sacral nerve stimulation motor and sensory amplitudes were highly correlated in our cohort, and subjects with motor response were significantly more likely to feel sensation of stimulation. This supports the theory that both motor efferent and sensory afferent portions of the sacral nerve may contribute to SNS mechanism.
Integrin Regulation of β-Catenin Signaling in Ovarian Carcinoma (2011)

Reversible modulation of integrin-regulated cell-matrix adhesion and epithelial (E)-cadherin-mediated cell-cell adhesion plays a critical role in the establishment of ovarian cancer metastases. In contrast to most epithelial cell-derived tumors that down-regulate E-cadherin expression during progression, acquisition of E-cadherin expression accompanies malignant transformation of the ovarian surface epithelium and is maintained in peritoneal metastases. Metastatic epithelial ovarian cancer cells are disseminated intraperitoneally and preferentially adhere via integrins to interstitial collagens in the peritoneal cavity. This study was undertaken to determine whether integrin engagement influences E-cadherin and β-catenin localization and function. The data demonstrate that multivalent integrin engagement results in increased internalization of E-cadherin, inhibition of GSK-3β, elevated levels of nuclear β-catenin, increased β-catenin-regulated promoter activation, and transcriptional activation of Wnt/β-catenin target genes. Blocking β-catenin transcriptional control with inhibitor of β-catenin and Tcf-4 reduces cellular invasion, suggesting a key role for β-catenin nuclear signaling in EOC invasion and metastasis. These studies support a model wherein cell-matrix engagement regulates the functional integrity of cell-cell contacts, leading to increased β-catenin nuclear signaling and enhanced cellular invasive activity. Furthermore, these results provide a mechanism for activation of Wnt/β-catenin signaling in the absence of activating mutations in this pathway.
Reduced fetal platelet counts in pregnancies with abnormal Doppler umbilical flow waveforms. (1989)

Fetal and maternal platelet counts were correlated with antenatal assessment of the umbilical-placental waveform. Forty singleton pregnancies were studied using Doppler ultrasound, and placental resistance was categorized as normal or high according to the systolic/diastolic ratio. We performed platelet counts on maternal and cord blood taken at the time of cesarean section. The high-resistance group had a mean fetal platelet count (218 +/- 53 x 10(3)/microliters) significantly lower than that of the normal-resistance group (314 +/- 76 x 10(3)/microliters) (P less than .001). This difference was evident in both the hypertensive and nonhypertensive subgroups of the high-resistance group. There was no difference in mean maternal platelet counts between the high- and normal-resistance groups.
GMR multilayers and head design for ultrahigh density magnetic recording (1996)

This paper describes materials development, device modeling, and initial test results for a novel GMR reproduce head for ultrahigh density recoding (/spl sim/ 10 Gbit/in/sup 2/). It consists simply of a 20-bilayer GMR multilayer, self-stabilized by intrinsic antiferromagnetic interlayer coupling, and self-biased by sense current into a bipolar, field-gradient-sensing bias state. Analogous to a dual magnetoresistive (DMR) such a GMR-DMR head is capable of achieving very high linear resolution without shields. Tape-test results using evaporated NiFe/Cu and sputtered NiFeCo/Cu agree reasonably well with theoretical expectations. 1/f noise in these GMR multilayers will also be discussed.
Selective N-acylation of gentamicin antibiotics - synthesis of 1-N-acyl derivatives. (1976)

Treatment of acid addition salts of aminoglycoside-aminocyclitol antibiotics of the gentamicin-sisomicin class, with one equivalent of triethylamine and an acylating agent results in selective formation of 1-N-acyl derivatives. This is in contrast to acylation of the antibiotic free bases which results in preferential acylation of other basic centres in the molecule. Origins of the observed selectivity are discussed. In vitro antibacterial activities of several new 1-N-acy1 derivatives of gentamicin, sisomicin and verdamicin are reported.
Immunological recognition of different forms of the neurotensin receptor in transfected cells and rat brain (1995)

In this work, the molecular forms of the rat neurotensin receptor (NTR) expressed in transfected Chinese hamster ovary (CHO) cells, in infected Sf9 insect cells and in rat cerebral cortex were immunologically detected by means of an anti-peptide antibody raised against a fragment of the third intracellular loop of the receptor. Immunoblot experiments against a fusion protein indicated that the anti-peptide antibody recognized, under denaturing conditions, the corresponding amino acid sequence within the NTR. In immunoblot analysis of membranes from NTR-transfected CHO cells, high levels of immunoreactivity were observed between 60 and 72 kDa, while only a faint labelling was observed at 47 kDa, the molecular mass deduced for the rat NTR cDNA. The bands of high molecular mass were no longer observed after deglycosylation of membrane proteins by peptide N-glycosidase F, indicating that they represented glycosylated forms of the receptor. Extracts of membranes derived from baculovirus-infected Sf9 insect-cells expressing the NTR provided a quite different immunoblot pattern, since the major band detected in that case was at 47 kDa, the molecular size of the non-glycosylated receptor. Taken together, these data show that, while most of the NTR protein was glycosylated in CHO cells, it was unglycosylated in Sf9 insect-cells. In addition, molecular sizes of the receptor proteins observed in these two cell lines differed from those obtained for the NTR endogenously expressed in the rat cerebral cortex of 7 day-old rats, where bands at 56 and 54 kDa were detected. Binding experiments carried out on membrane preparations obtained from baculovirus-infected Sf9 cells demonstrated that the immunogenic sequence was still accessible to the antibody when the receptor was embedded in the cell membrane. Immunohistochemical studies carried out on both transfected CHO cells and infected Sf9 cells confirmed this interpretation and further indicated that the antibody could be applied in the visualization of the receptor.
Field-Scale Monitoring Studies To Evaluate Mobility of Pesticides in Soils and Groundwater (1991)

The United States Environmental Protection Agency (EPA) may require data from ground-water monitoring studies to support the registration of pesticide products under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) sections 3(c)5 and 3(c)7. Data from ground-water monitoring studies are used both to determine the likelihood that a pesticide will leach and to detect the presence of a pesticide in ground water from years of use. Fieldscale monitoring studies are necessary because patterns of pesticide degradation and movement in the field are influenced by a wide variety of natural environmental factors that cannot be duplicated in the laboratory. Monitoring studies have been required for 37 compounds when residues of the pesticide are reported in ground water or when the Agency has evaluated the pesticide as a potential "leacher," based on a review of it's persistence and mobility. This paper explains the history of ground-water monitoring requirements for the Office of Pesticide Programs of EPA and events and issues that led to the development of the monitoring guidance. New directions in small-scale monitoring studies are described. Large-scale ground-water monitoring is mentioned briefly.

Carbon with hierarchical pores from carbonized metal–organic frameworks for lithium sulphur batteries (2013)

This paper presents a novel method and rationale for utilizing carbonized MOFs for sulphur loading to fabricate cathode structures for lithium-sulphur batteries. Unique carbon materials with differing hierarchical pore structures were synthesized from four types of zinc-containing metal-organic frameworks (MOFs). It is found that cathode materials made from MOFs-derived carbons with higher mesopore (2-50 nm) volumes exhibit increased initial discharge capacities, whereas carbons with higher micropore (<2 nm) volumes lead to cathode materials with better cycle stability.

Interconnection and assembly of LCDs (2002)

The LCD market is demanding larger displays with higher resolution in smaller, thinner, lighter packages at lower cost. As LCD displays were designed to meet these market needs, new interconnection and assembly technologies were required. For some applications final product packaging is a dominant product differentiator. Interconnection between conductors on the glass LCD cell and the drive electronics has evolved from coarse pitch conductive elastomers to heat seal connectors to anisotropic conductive film bonded tape carrier packages to direct chip attachment, with the older technologies retaining certain market niches. The overall display package has become thinner and lighter with the deployment of newer packaging and interconnection technologies. This paper reviews the evolution of interconnection technology in the display industry from coarse pitch conductive elastomers to fine direct chip attachment. Trends in tape carrier package and direct chip attachment technology are emphasized. Industry trends in display packaging and examples of product differentiation through improved packaging are discussed.
Lifetime of ferroelectric cathodes (2001)

We study the lifetime and emission properties of ferroelectric cathodes made of perovskites with the ABO3 composition. To excite electron emission, we applied negative driving pulses with different amplitudes and durations to the rear electrode of the ferroelectric cathodes. The composition of the samples before and after the experiments was checked by energy dispersive spectroscopy and by Auger electron spectroscopy. The image and the structure of the emitting surface of the samples were studied by scanning electron microscopy. It was found that the lifetime of the tested cathodes depends strongly on their composition as well as on the parameters of the driving pulse. Namely, the driving pulse causes a substantial damage in lead–zirconium–titanate-type samples and a structural change in the surface of barium–titanate-type samples. In addition, fast deterioration was found in the emission properties of the tested cathodes along with increasing number of driving pulses. We discuss our results within the framework of the incomplete surface discharge model.
Development of Enhanced Lateral Flow test Devices for Point-of-Care Diagnostics (2013)

Lateral flow Imunoassays (LFIA) are common, simple to use point-of-care devices for the diagnostic market. Conventionally LFIAs are limited in their complexity since they are optimized for minimally trained operators. Paper-based analytical devices (PAD) are advanced sensors based on a wide range of recently developed techniques for complex analytical methods. In this research, a point-of-care (POC) immunosensor was developed based on techniques adapted from lateral flow and paper-based analytical devices. Alternating layers of paper and tape were used to expand the common 2D design of lateral flow tests to 3D in order to enable complex fluid flow control. Four fluidic valves were integrated for automatic sequential loading of three different fluids to a detection area. Fabrication processes, reagent concentrations, materials and device geometries were optimized and a chip-yield of 92% was achieved. A three step alkaline phosphatase (ALP)-based enzyme-linked immunosorbent assay (ELISA) procedure with Rabitt IgG as model analyte was used to prove the working principle of the sensor. After optimization of crucial assay parameters practicability was verified by visual detection of signal development on nitrocellulose membrane after reaction of ALP and NBT/BCIP with a good detection limit of 4.8 fm.
Dissolution Rate of Al2O3 into Molten CaO-SiO2-Al2O3 Slags. (2002)

The dissolution rate of Al2O3 into the CaO-SiO2-Al2O3 slag system was investigated at 1 873 K by employing a novel experimental method which involved continual measurement of the torque variation on a rotating alumina rod dipped into a molten slag. Measured torque variation was successfully related to the dissolution rate of the rod. The dissolution rate of alumina was found affected by a number of factors: the rate increased with increasing temperature, the rotating speed of the rod, the CaO content in the slag, and the Al2O3 content in the slag for a fixed CaO content. It was found that the dissolution rate was highly dependent on the viscosity and the diffusivity of slags. The activation energy obtained from an Arrhenius type analysis was in the range of 84 kJ mol-1 . It was concluded that the dissolution of Al2O3 into the CaO-SiO2-Al2O3 slag system was controlled by the mass transfer in the slag phase. An iso-dissolution rate diagram was constructed for the dissolution of Al2O3 into the CaO-SiO2-Al2O3 slag system at 1 873 K.
Aqueous Piperazine/N-(2-Aminoethyl) Piperazine for CO2 Capture (2013)

A novel blend of piperazine (PZ) with N-(2-aminoethyl) piperazine (AEP) has been proposed as a superior solvent for CO2 capture from coal-fired flue gas. Blending PZ with AEP can remediate the precipitation issue of concentrated PZ while maintaining its high CO2 absorption rate, and high resistance to degradation. Although PZ/AEP has a lower CO2 capacity than concentrated piperazine, its higher heat of absorption may offset the negative effect on energy consumption. PZ/AEP also shows a milder nitrosamine issue than concentrated piperazine. A novel method for synthesizing AEP using PZ and monoethanolamine (MEA) was also developed to lower the solvent cost in industry application.
Pharmacokinetics of Nevirapine: Once-Daily Versus Twice-Daily Dosing in the 2NN Study (2005)

The daily exposure to nevirapine (AUC24h) was similar for the 400 mg once-daily and the 200 mg twice-daily dosing regimens. The Cmin of nevirapine is lower and the Cmax of nevirapine is higher for the once-daily regimen as compared to the twice-daily regimen. As a result, 200 mg nevirapine dosed twice daily may be preferred over 400 mg nevirapine dosed once daily.
Photochemical Synthesis of N-Substituted 3-Hydroxy-2-pyrrolidinones (2005)

Three-Year Experience with the White-Yu Endovascular GAD Graft for Transluminal Repair of Aortic and Iliac Aneurysms (1997)

Purpose: To report a > 3-year experience with a modular, balloon-expandable endovascular graft used for aneurysm exclusion in the aorta and other arteries. Methods: The customized White-Yu Endovascular GAD Graft, a woven polyester prosthesis with an intrinsic Elgiloy wire graft attachment system along the body of the graft, is a flexible endograft design available in straight, tapered, and bifurcated versions that can be delivered transluminally through 18F to 24F sheaths. Results: Since July 1993, 93 patients have received the White-Yu endograft for treatment of 76 abdominal aortic, 3 thoracic aortic, 13 iliac, and 1 popliteal aneurysms. Of the 79 aortic procedures, 39 involved straight tube grafts, 20 were tapered aortoiliac models, and 20 were bifurcated devices. Success rates for tube grafts were 81% in the abdominal aorta and 100% for the thoracic aorta; 5 primary endoleaks (14%) and 2 conversions to surgery (5.6%) occurred with this graft type. Aortoiliac grafts were deployed successfully in 95% (19/20) of cases with 1 conversion (5%) due to thrombosis. Seventy-five percent of the bifurcated endograft procedures were successful, with 4 conversions (20%) for technical failures and 1 graft thrombosis. Four additional endografts were deployed to treat two primary and two secondary endoleaks in tube graft patients. Two access-related arterial injuries were treated surgically. There was one case of embolus to the distal femoral artery but no microembolization. Overall perioperative (30-day) mortality was 3.1%. Over a mean 18-month follow-up (range 2 to 39), no late graft thrombosis, stenosis, or graft migration has been seen on CT scans or X ray. Endoleak has not been detected in any aortoiliac or bifurcated graft. Aneurysm size has diminished consistently in successfully treated cases. Conclusions: The White-Yu endograft appears to offer a safe, efficacious, and minimally invasive means of excluding aneurysms from the circulation. Improvements in patient selection, surgical techniques, and equipment have reduced the incidence of endoleak and conversion to open repair over the course of the evaluation.
