A multi-scale cascade fully convolutional network face detector (2016)

Face detection is challenging as faces in images could be present at arbitrary locations and in different scales. We propose a three-stage cascade structure based on fully convolutional neural networks (FCNs). It first proposes the approximate locations where the faces may be, then aims to find the accurate location by zooming on to the faces. Each level of the FCN cascade is a multi-scale fully-convolutional network, which generates scores at different locations and in different scales. A score map is generated after each FCN stage. Probable regions of face are selected and fed to the next stage. The number of proposals is decreased after each level, and the areas of regions are decreased to more precisely fit the face. Compared to passing proposals directly between stages, passing probable regions can decrease the number of proposals and reduce the cases where first stage doesn't propose good bounding boxes. We show that by using FCN and score map, the FCN cascade face detector can achieve strong performance on public datasets.
Cermet Resistors on Ceramic Substrates (1981)

Cermet (CrSiO) has been used extensively for chip resistors. The application for CrSiO on CrCuCr metallized ceramic substrates is described. The process was designed for potential high volume production needs. Basic operations are described, including radio frequency (RF) magnetron sputtering, photoprocessing, plasma etching, and trimming. Resistor design features have more flexibility over thick film resistors. A much wider aspect ratio is achieved by the improved line resolution. Low resistor values employ a comb design; high resistor values employ convention serpentine designs. Consistent with the IBM data base for silicon substrates, film resistivity, and thermal coefficient of resistance (TCR) are controlled by CrSiO composition and subsequent thermal treatments of the film. Thermal stabilization is significantly improved by film annealing.
[Influence of light through the eyes on metabolism and hormones]. (1991)

The eye plays a double role: on the one side it is the optic camera, on the other side independent of the optic path ways it is the light receptor which stimulates the retino-hypothalamique pathway of the endocrine-visceral system. To determine this influence, we compared the metabolisme (water balance, blood sugar and blood cell count) as well as the hormones (ACTH, Cortisol) of fifty patients with bilateral almost total cataract, before (practically blind) and after cataract surgery (regain of light). There was a significant difference between the metabolic and hormonal values before and after cataract extraction, reaching physiologically normal levels due to the stimulating influence of light after the operation.
Human Liver MAO-A and MAO-B Separated by Immunoaffinity Chromatography with MAO-B-Specific Monoclonal Antibody (1982)

A monoclonal antibody was used to prepare immunoaffinity columns that efficiently bind monoamine oxidase B activity but not monoamine oxidase A activity from detergent extracts of human liver mitochondria. The only discrete polypeptide component that eluted from affinity columns with potassium thiocyanate migrated in sodium dodecyl sulfate-polyacrylamide gels with an apparent molecular weight of 59,000, as expected for human monoamine oxidase B. These results support the hypothesis that there is an intrinsic structural difference between monoamine oxidase A and B and demonstrate that immunoaffinity chromatography can physically resolve the two enzyme species in liver extracts.
Amphiphilic Poly(3-hexylthiophene)-Based Semiconducting Copolymers for Printing of Polyelectrolyte-Gated Organic Field-Effect Transistors (2013)

Polyelectrolytes are promising electronically insulating layers for low-voltage organic field effect transistors. However, the polyelectrolyte–semiconductor interface is difficult to manufacture due to challenges in wettability. We introduce an amphiphilic semiconducting copolymer which, when spread as a thin film, can change its surface from hydrophobic to hydrophilic upon exposure to water. This peculiar wettability is exploited in the fabrication of polyelectrolyte-gated field-effect transistors operating below 0.5 V. The prepared amphiphilic semiconducting copolymer is based on a hydrophobic regioregular poly(3-hexylthiophene) (P3HT) covalently linked to a hydrophilic poly(sulfonated)-based random block. Such a copolymer is obtained in a three-step strategy combining Grignard metathesis (GRIM), atom transfer radical polymerization (ATRP) processes, and a postmodification method. The structure of the diblock copolymer was characterized using FT-IR, 1H NMR spectroscopy, and gel permeation chromatography (GPC).
Fractionally spaced equalization for analog cellular data modems (2002)

The authors consider a simple add-on system to analog cellular radios to offer 9600 b/s data services. The feasibility of using a fractionally spaced equalizer with a burst noise detector is considered. The authors examine equalization performance for subcarrier-based quadrature amplitude modulation (QAM). The performance of a T/4 and a T/2 spaced equalizer is compared with the performance of a symbol spaced equalizer for low to medium signal-to-noise ratios (SNRs). Performance criteria are minimum mean square error, timing sensitivity, SNR after equalization, signal-to-interference ratio (SIR) after equalization, and peak distortion (PD) after equalization. By means of simulation the convergence aspects of the T/2 spaced equalizer were investigated after differing burst and correlated noise scenarios. A noise detection plus equalizer control scheme is proposed and evaluated to maintain operation of the equalizer under burst noise conditions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Intelligent optimization scheduling of steelmaking and continuous casting production and its application (2010)

Scheduling of steelmaking-continuous casting production is an intractable problem, and it is generally difficult to achieve effective scheduling using a single method. In this paper, a novel scheduling method is presented for scheduling the steelmaking and continuous casting production. Combing the mathematical programming and expert system technique, and through the procedures of human-computer interaction and fuzzy comprehensive evaluation, a feasible and optimized production scheduling scheme can be produced and provided to the steelmaking and continuous casting production process. The developed scheduling software based on the proposed scheduling strategy has been successfully applied in a large steel plant in China. The results demonstrate that the proposed scheduling strategy not only can satisfy the requirement of practical production, but also has broad prospects for promotion.
Optimization of IPTV Multicast Traffic Transport over Next Generation Metro Networks (2006)

This paper describes the challenges of delivering multicast IPTV services in terms of resource usage and user experiences, and proposes an approach to minimize the resources to be used while keeping the right quality of the services offered. The paper describes a generic network model to provide the IPTV services and states the problems this network faces to control bandwidth needs while user perceived quality is good enough. A solution is proposed, following an evolutionary approach from the existing approach to the optimal solution that is based on the integration of the transport and access networks with the IMS and the IPTV applications
Effect of Vanadium Incorporation on Electrochemical Performance of LiFePO<sub>4</sub> for Lithium-Ion Batteries (2011)

A series of LiFe1–xVxPO4/C samples have been successfully prepared using a two-step solid-state reaction route. The effect of vanadium incorporation on the performance of LiFePO4 has systematically been investigated with X-ray diffraction, Raman spectroscopy, charge/discharge measurements, and cyclic voltammetry tests. It is found that V incorporation significantly enhances the electrochemical performance of LiFePO4. Particularly, the LiFePO4/C sample with 5 at. % vanadium doping exhibits the best performance with a specific discharge capacity of 129 mAh g–1 at 5.0 C after 50 cycles; the capacity retention ratio is higher than 97.5% at all C rates from 0.1 to 5.0 C. X-ray absorption spectroscopy results show that the valence of V in LiFe0.95V0.05PO4/C is between +3 and +4. It is confirmed that the samples with x ≤ 0.03 are in single phase, whereas the samples with 0.05 ≤ x < 1.00 contain two impurity phases: Li3V2(PO4)3 and LiVOPO4. A clear feature of vanadium incorporation in LiFePO4 has been specified.
Disturbance Effect on Time-Dependent Yield Stress Measurement of Bentonite Suspensions (2013)

Abstract Disturbance effect on time-dependent yield stress measurement of bentonite suspension was investigated using vane and cone and plate geometry. With cone and plate geometry, the disturbance occurs as a result of the large strains the suspensions are subjected to when placed on the lower plate and when the cone is lowered to the testing position before the actual shear stress is applied. As an alternative, vane geometry has been used to measure yield stress in bentonite suspension to (1) minimize the placing disturbance, and (2) eliminate the loading disturbance. Even though a minimal amount of disturbance was still induced by vane geometry, it was assumed that the amount of disturbance was small enough to be ignored compared to that with cone and plate geometry. Yield stresses of bentonite suspensions at different weight fractions and various resting times were determined from stress ramp tests. Linear relationships were developed between yield stresses measured with the different geometries. Disturbance rapidly increased up to approximately 50 % with resting times, then converged at long resting times (60 % at 10 days). This indicates that cone and plate geometry significantly underestimated the actual yield stress of the tested material because of disturbance. Based on the quantified disturbance, a method to predict the undisturbed yield stress from disturbed one was proposed. The observations were interpreted with structural kinetics.
Delay and power model for current-mode signaling in deep submicron global interconnects (2003)

In this paper, closed-form expressions of delay and power dissipation based on the effective lumped element resistance and capacitance approximation of distributed RC lines are presented. A new closed-form solution of delay under step input excitation is developed, exhibiting an accuracy that is within 5% for a wide range of parameters. The usefulness of this solution is that both resistive and capacitive load termination is accurately modeled for use in current mode signaling. A new power dissipation model for current-mode signaling is developed to understand the design tradeoffs between current and voltage sensing. Based on these formulations, a comparison between voltage-mode repeater insertion technique and current-mode signaling over long global deep submicron interconnects is presented.
Different intrahepatic distribution of phosphatidylglycerol and phosphatidylserine liposomes in the rat (1997)

Liposomes with diameters of 200 to 400 nm containing phosphatidylserine (PS) or phosphatidylglycerol (PG) were injected intravenously into rats. Two hours after injection, 75% of the injected dose of PS liposomes was found in the liver and only 10% found in the spleen, while 35% of the PG liposomes was found in the liver and as much as 40% was found in the spleen. Cell-isolation experiments revealed the following remarkable difference in the intrahepatic distribution between the two liposome formulations: the PS liposomes distributed in about equal amounts to Kupffer cells and hepatocytes, despite their size (200-400 nm) exceeding that of the endothelial fenestrae (average 150 nm), whereas the PG liposomes were only taken up by the Kupffer cells and not at all by the hepatocytes. Double-label studies, using liposomes in which the lipid-moiety was radio labeled with [3H]cholesteryloleylether ([3H]CE) and the water phase with [14C]sucrose, showed that the liposomes were taken up as intact particles. These observations were confirmed through electron microscopy by determining the in situ localization of liposome-encapsulated colloidal gold particles in thin sections of liver and spleen. The differences in organ distribution are ascribed to differences in opsonization patterns of the two liposomal surfaces. For the difference in intrahepatic distribution, we offer the following two explanations: the exploitation of the blood cell-mediated forced sieving concept and the indication of a PS-specific pharmacological effect on the dimensions of the fenestrations.

Human Serum Lipoproteins as Inhibitors of Haemagglutination for Selected Togaviruses (1974)

SUMMARY Human serum was fractionated by ultracentrifuging and the non-specific inhibitory activity for the togaviruses, Japanese encephalitis virus and rubella virus, was found chiefly in the very low density lipoprotein (VLDL) and low density lipoprotein (LDL) fractions. The specific inhibitory activity per mg protein or lipid of each lipoprotein fraction was greater for Japanese encephalitis virus. Japanese encephalitis virus was significantly more sensitive to VLDL than LDL whereas rubella virus was equally sensitive to either.
Deep Learning and Multi-Sensor Fusion for Glioma Classification Using Multistream 2D Convolutional Networks (2018)

This paper addresses issues of brain tumor, glioma, grading from multi-sensor images. Different types of scanners (or sensors) like enhanced T1-MRI, T2-MRI and FLAIR, show different contrast and are sensitive to different brain tissues and fluid regions. Most existing works use 3D brain images from single sensor. In this paper, we propose a novel multistream deep Convolutional Neural Network (CNN) architecture that extracts and fuses the features from multiple sensors for glioma tumor grading/subcategory grading. The main contributions of the paper are: (a) propose a novel multistream deep CNN architecture for glioma grading; (b) apply sensor fusion from T1-MRI, T2-MRI and/or FLAIR for enhancing performance through feature aggregation; (c) mitigate overfitting by using 2D brain image slices in combination with 2D image augmentation. Two datasets were used for our experiments, one for classifying low/high grade gliomas, another for classifying glioma with/without 1p19q codeletion. Experiments using the proposed scheme have shown good results (with test accuracy of 90.87% for former case, and 89.39 % for the latter case). Comparisons with several existing methods have provided further support to the proposed scheme. keywords: brain tumor classification, glioma, 1p19q codeletion, glioma grading, deep learning, multi-stream convolutional neural networks, sensor fusion, T1-MR image, T2-MR image, FLAIR.
Burkholderia cenocepacia O antigen lipopolysaccharide prevents phagocytosis by macrophages and adhesion to epithelial cells (2009)

Chronic respiratory infections by the Burkholderia cepacia complex (Bcc) are of great concern to patients with cystic fibrosis. Bcc isolates may survive intracellularly within amoebae, respiratory epithelial cells and macrophages. The molecular mechanisms facilitating colonization and pathogenesis remain unclear. Given the importance of bacterial adhesion to host surfaces in microbial pathogenesis, we investigated the role of the O antigen LPS in the interaction of Burkholderia cenocepacia, a member of the Bcc, with macrophages and epithelial cells. Our results demonstrated that the O antigen modulates phagocytosis but does not affect intracellular survival of B. cenocepacia. Internalization of strains that lack O antigen was significantly increased compared to that of their isogenic smooth counterparts. However, no differences between rough and smooth strains were found in their ability to delay phagosomal maturation. We also found that the O antigen interfered with the ability of B. cenocepacia to adhere to bronchial epithelial cells, suggesting that this polysaccharide may mask one or more bacterial surface adhesins.
Biomechanical Evaluation of a New Total Posterior-Element Replacement System (2006)

The TOPS implant almost ideally restored the ROM in lateral bending and axial rotation compared to that of the intact specimen. In the sagittal plane, 85% of the intact ROM could be obtained. The ROM in axial rotation as a function of flexion and extension angle also mimics the biomechanical behavior of the posterior complex of a lumbar spine. This relationship between ROM and posture emphasizes the importance of a proper implantation.

Abnormal Head Posture in Restrictive Strabismus (1995)

Ocular torticollis, a spontaneous anomalous head posture, may be a presenting clinical sign of restrictive strabismus. For proper management, restrictive strabismus must be distinguished from paralytic strabismus using a variety of means, including: tests of versions, presence of incomitance and secondary deviation, saccadic velocity, forced duction, and force generation.Causes of restrictive strabismus include congenital fibrosis, Brown syndrome, orbital anomalies, globe anomalies, myopathies, traumatic muscle and connective tissue entrapment, endogenous orbital mass, implanted orbital hardware, and muscle shortening. The cornerstone of management of ocular torticollis due to restrictive strabismus is release of the restriction to ocular rotation, usually by strabismus surgery.
International mobile satellite communications for the transport industry (1991)

INMARSAT, operating four geostationary satellites with worldwide coverage, was originally intended for merchant ships, but now addresses the marine, land mobile, portable and aviation international markets. INMARSAT-C is a small, low power terminal ideal for fitting in vehicles such as trucks and cars. The relative simplicity of the INMARSAT-C system means that data, at 600 bit/s, is the only means of communicating, but INMARSAT have designed some innovative protocols into the specification which allow data reporting, polling and group calling, as well as standard messaging.
Far-infrared investigation of the generalized Lyddane-Sachs-Teller relation using ZnS-diamond composites (1990)

The optical properties of hot-pressed ZnS-diamond composites have been investigated in the far ir, where the wavelength is much larger than the particle size. A Kramers-Kronig analysis of the measured reflectivity in this vibrational spectral region was used to determine the dielectric function of samples with diamond volume fill fractions f as large as 55%. From these results the f dependences of two experimental quantities are determined: the ratio of the second moments of the longitudinal and transverse energy-loss functions and the ratio of the dc and high-frequency dielectric constants. Agreement with the predictions of the generalized Lyddane-Sachs-Teller relation is obtained over the entire fill-fraction range. We also find that the experimental results are compatible with those obtained within the Bruggeman effective-medium approximation.
Preferred Orientation Control and Characterization of AlN Thin Films Using Reactive Sputtering (2004)

This article presents a study of the influence of the sputtering parameters on the preferred orientation of polycrystalline aluminum nitride thin films. Aluminum nitride films are deposited by reactive dc magnetron sputtering using an aluminum target in an N2/Ar gas mixture. In this study, the influences of substrate temperature and target-substrate spacing on film property will be studied. Measurements of the piezoelectric strain constant d33 are performed in order to effectively evaluate the piezoelectric characteristics of the films. X-ray diffraction (XRD) measurements are also made to investigate the influence on the AlN crystallographic orientation. The film texture index Πhkl is used to quantify how much of the film is oriented along the [hkl] direction. The calculated maximum mean d33 is 2.7 pm/V at 300°C for AlN/Mo.
Immunization with a novel Clostridium perfringens epsilon toxin mutant rETXY196E-C confers strong protection in mice (2016)

Epsilon toxin (ETX) is produced by toxinotypes B and D of Clostridium perfringens. It can induce lethal enterotoxemia in domestic animals, mainly in sheep, goats and cattle, causing serious economic losses to global animal husbandry. In this study, a novel and stable epsilon toxin mutant rETX(Y196E)-C, obtained by substituting the 196th tyrosine (Y196) with glutamic acid (E) and introducing of 23 amino acids long C-terminal peptide, was determined as a promising recombinant vaccine candidate against enterotoxemia. After the third vaccination, the antibody titers against recombinant wild type (rETX) could reach 1:10(5) in each immunized group, and the mice were completely protected from 100 × LD50 (50% lethal dose) of rETX challenge. The mice in 15 μg subcutaneously immunized group fully survived at the dose of 500 × LD50 of rETX challenge and 80% of mice survived at 180 μg (1000 × LD50) of rETX administration. In vitro, immune sera from 15 μg subcutaneously immunized group could completely protect MDCK cells from 16 × CT50 (50% lethal dose of cells) of rETX challenge and protect against 10 × LD50 dose (1.8 μg) of rETX challenge in mice. These data suggest that recombinant protein rETX(Y196E)-C is a potential vaccine candidate for future applied researches.
