Solid State Imaging Techniques. On-chip Inner-Layer Lens Technology for an Improvement in Photo-sensitive Characteristics of a CCD Image Sensor. (1996)

An on-chip inner-layer lens has been developed to improve the photo-sensitivity and smear of CCD image sensors. The inner-layer lens structure consists of a boron-phospho-silicate-glass (BPSG) layer and a heat melting transparent resin. The refractive indices for the inner-layer lens was higher than the BPSG layer and the planarization layer. Taking the incident angle into account, we have applied a new three dimentional simulation to the inner-layer lens to investigate the optical pass. We fabricate a 1/4-type IT-CCD image sensor with an inner-layer lens. This fabricated results of an image sensor has been explained well by the new three dimentional optical simulation. The increase of photo-sensitivity using the inner-layer lens technology is 16% without deterioration in the CCD characteristics. Furthermore using the inner-layer lens reduces the smear value by 70%.
<title>Java-based PACS and reporting system for nuclear medicine</title> (2000)

In medical imaging practice, images and reports often need be reviewed and edited from many locations. We have designed and implemented a Java-based Remote Viewing and Reporting System (JaRRViS) for a nuclear medicine department, which is deployed as a web service, at the fraction of the cost dedicated PACS systems. The system can be extended to other imaging modalities. JaRRViS interfaces to the clinical patient databases of imaging workstations. Specialized nuclear medicine applets support interactive displays of data such as 3-D gated SPECT with all the necessary options such as cine, filtering, dynamic lookup tables, and reorientation. The reporting module is implemented as a separate applet using Java Foundation Classes (JFC) Swing Editor Kit and allows composition of multimedia reports after selection and annotation of appropriate images. The reports are stored on the server in the HTML format. JaRRViS uses Java Servlets for the preparation and storage of final reports. The http links to the reports or to the patient's raw images with applets can be obtained from JaRRViS by any Hospital Information System (HIS) via standard queries. Such links can be sent via e-mail or included as text fields in any HIS database, providing direct access to the patient reports and images via standard web browsers.
Design of a Passively-Powered, Programmable Sensing Platform for UHF RFID Systems (2007)

This paper presents a wireless, battery-free, platform for sensing and computation that is powered and read by a standards compliant ultra-high frequency (UHF) radio frequency identification (RFID) reader. The WISP (wireless identification and sensing platform) includes a fully-programmable 16 bit microcontroller with analog-to-digital converter. The microcontroller firmware implements portions of the electronic product code (EPC) class 1 generation 1 protocol. When queried, the platform communicates arbitrary sensor data by emulating an EPC tag whose ID encodes the desired sensor data; the required 16-bit CRC is computed dynamically by the microcontroller. The RFID reader reports the received tag ID to application software which can interpret the information contained in the tag ID. The programmability of the WISP along with its implementation as a PCB allows for flexible integration of arbitrary low-power sensors. Furthermore, sensors are also exclusively powered from the RFID reader resulting in a completely battery free device. Sensors integrated into the WISP platform so far include light, temperature, and rectified voltage, and are shown experimentally to have an operating range of up to 4.5m. To the authors' knowledge, WISP is the first fully programmable computing platform that can operate using power transmitted from a long-range (UHF) RFID reader and communicate arbitrary, multi-bit data in a single response packet.
Synthesis of derivatives of alkylamino alkyloxy propanol structures by <i>N</i>‐alkylation, acylation, and nitration. Application as fuel additives (1997)

Abstract Polyfunctional compounds were prepared by alkylation, acylation, and nitration of hydroxyl and amine functions of the following alkanolamine ether structures: (di)alkylamino alkyloxy propanol, hydroxy alkyloxy (di)alkylamino propanol, and their dimer compounds. The resulting compounds were characterized by conventional spectroscopic methods, and complete nuclear magnetic resonance data are given. These reactions extented the application of these propanic compounds to use as multipurpose fuel additives. In particular, they enhance phase stability and improve the cetane number in ethanol‐diesel fuel blends.
Thin-Film Piezoelectric-on-Silicon Resonant Transformers (2013)

This paper reports the performance of lead–zirconate-titanate (PZT)-on-silicon electromechanical resonators as thin-film piezoelectric transformers. The PZT-on-silicon resonators rely on the odd harmonics of the contour length-extensional modes to provide a convenient means for voltage and current transformations with a single layer of piezoelectric PZT. The resistive-load-dependent voltage gains and efficiencies are derived along with the peak efficiencies and open circuit voltage gains. The models of efficiency and voltage gain are compared to the experimental measurements of fabricated PZT-on-silicon piezoelectric transformers with 2, 4, and 10 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\mu{\rm m}$</tex></formula> of device silicon. The resonant frequencies of the devices range between 14 and 19 MHz. Peak efficiencies as high as 62% are measured and open circuit voltage gains as high as 5.7 are extracted from the measurements. The measured efficiencies with 50- <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\Omega$</tex></formula> loads compare within 14% of the models on average (25% peak error). The extracted open-circuit voltage gains and their models compare within 22% on average (67% peak error). The trade between the load-dependent efficiencies and voltage gains are also presented for the <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$n=3$</tex></formula> , 5, 9, and 13 harmonics. <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\hfill[2012{\hbox{-}}0339]$</tex></formula>
Methods for the control of large medium voltage motors; application considerations and guidelines (2003)

Starting and control methods available for medium voltage induction motors, (2.4 kV-7.2 kV), in the petrochemical industry are continually changing in terms of application considerations due to the evolution of available products and changing characteristics of the machine and processes. This paper summarizes several common methods and provides application guidelines for proper selection considering the distribution system, driven equipment, speed-torque issues, process requirements, starter method limitations and economics. Starting means reviewed include medium voltage soft starters, variable frequency drives, and autotransformer, capacitor, reactor, captive transformer, across the line controllers as well as fluid couplers.

PNA-Directed Triple-Helix Formation by<i>N</i> <sup>7</sup>-Xanthine (2005)

We report the first example of alkylation of underivatized xanthine with chloroacetic acid to yield a separable mixture of N 7- and N 9-(methylenecarboxyl)xanthine and its conversion to a peptide nucleic acid monomer compatible with Fmoc-based oligomerization chemistry. Additionally, we have simultaneously prepared the N 7 - and N 9-PNA monomers of guanine by alkylation of 2-N-isobutyrylguanine which were subsequently separated. Molecular modeling of the nucleobase base triplets indicates that N 7-xanthine and N 7-guanine form isomorphous triplets with adenine and guanine, respectively. We also show that polyamides containing N 7-xanthine are compatible with triple-helix formation.
Building Discriminative User Profiles for Large-scale Content Recommendation (2015)

Content recommendation systems are typically based on one of the following paradigms: user based customization, or recommendations based on either collaborative filtering or low rank matrix factorization methods, or with systems that impute user interest profiles based on content browsing behavior and retrieve items similar to the interest profiles. All of these systems have a distinct disadvantage, namely data sparsity and cold-start on items or users. Furthermore, very few content recommendation solutions explicitly model the wealth of information in implicit negative feedback from the users. In this paper, we propose a hybrid solution that makes use of a latent factor model to infer user interest vectors. The hybrid approach enables us to overcome both the data sparsity and cold-start problems. Our proposed method is learned purely on implicit user feedback, both positive and negative. Exploiting the information in the negative feedback allows the user profiles generated to be discriminative. We also provide a Map/Reduce framework based implementation that enables scaling our solution to real-world recommendation problems. We demonstrate the efficacy of our proposed approach with both offline experiments and A/B tests on live traffic on Yahoo properties.
Clinical Heterogeneity of Atypical Pantothenate Kinase-Associated Neurodegeneration in Koreans (2016)

We found considerable phenotypic heterogeneity in Korean adults with atypical PKAN. The age of onset may influence the presentation of extrapyramidal symptoms.
Biotin-Streptavidin Competition Mediates Sensitive Detection of Biomolecules in Enzyme Linked Immunosorbent Assay (2016)

Enzyme Linked Immunosorbent Assay (ELISA) is the gold standard assay for detecting and identifying biomolecules using antibodies as the probe. Improving ELISA is crucial for detecting disease-causing agents and facilitating diagnosis at the early stages of disease. Biotinylated antibody and streptavidin-conjugated horse radish peroxide (streptavidin-HRP) often are used with ELISA to enhance the detection of various kinds of targets. In the present study, we used a competition-based strategy in which we pre-mixed free biotin with streptavidin-HRP to generate high-performance system, as free biotin occupies some of the biotin binding sites on streptavidin, thereby providing more chances for streptavidin-HRP to bind with biotinylated antibody. ESAT-6, which is a protein secreted early during tuberculosis infection, was used as the model target. We found that 8 fM of free biotin mixed with streptavidin-HRP anchored the higher detection level of ESAT-6 by four-fold compared with detection without free biotin (only streptavidin-HRP), and the limit of detection of the new method was 250 pM. These results suggest that biotin-streptavidin competition can be used to improve the diagnosis of analytes in other types of sensors.
Coupling Agents as Adhesion Promoters (1971)

ABSTRACT ABSTRACT An extensive review has been made of the literature from 1950 to the present to include all work in the area of coupling agents and their use toward improving adhesion. The types of agents studied, mechanisms by which they act, substrates, adhesive systems, and theories of adhesion are all considered. By far the most common system is silane agent on a glass substrate, and a covalent siloxane linkage is proposed as the operative mechanism. Phosphorus esters and chromium-acid complexes are also known to be effective, and similar mechanisms are postulated. Other species will adsorb on adherend surfaces to provide an adhesive interlayer. The use of coupling agents as admixtures with adhesives and the use and mechanisms of their behavior on metallic substrates have not been thoroughly studied until recently.

LLC converter combined with switched capacitor for high voltage applications (2013)

This paper presents a new LLC converter combined with switched capacitor for high voltage applications. In the proposed converter, the flying capacitor of the switched capacitor is divided into two parts, and they are used as resonance capacitors of an LLC converter. The proposed method reduces the switch voltage stress to a half of the input voltage, and the current in switches are a half of that in transformer. In addition, by increasing the number of switches and capacitors to connect, the proposed converter can be adapted for higher input voltage. The principle of operation and the characteristics of the proposed converter circuit are analyzed and verified on a 400 V input 24V/5A output experimental prototype, of which efficiency is 93.1% at rating condition.
Regulation of urinary bladder smooth muscle contractions by ryanodine receptors and BK and SK channels (2000)

This study examines the roles of voltage-dependent Ca(2+) channels (VDCC), ryanodine receptors (RyRs), large-conductance Ca(2+)-activated K(+) (BK) channels, and small-conductance Ca(2+)-activated K(+) (SK) channels in the regulation of phasic contractions of guinea pig urinary bladder smooth muscle (UBSM). Nisoldipine (100 nM), a dihydropyridine inhibitor of VDCC, abolished spontaneous UBSM contractions. Ryanodine (10 microM) increased contraction frequency and thereby integrated force and, in the presence of the SK blocker apamin, had a greater effect on integrated force than ryanodine alone. Blocking BK (iberiotoxin, 100 nM) or SK (apamin, 100 nM) channels increased contraction amplitude and duration but decreased frequency. The contractile response to iberiotoxin was more pronounced than to apamin. The increases in contraction amplitude and duration to apamin were substantially augmented with ryanodine pretreatment. These results indicate that BK and SK channels have prominent roles as negative feedback elements to limit UBSM contraction amplitude and duration. RyRs also appear to play a significant role as a negative feedback regulator of contraction frequency and duration, and this role is influenced by the activity of SK channels.
Deformation twinning in boron carbide particles within nanostructured Al 5083/B<sub>4</sub>C metal matrix composites (2010)

The presence of deformation twins is documented in boron carbide reinforcement particles within a nanostructured Al 5083/B4C metal matrix composite. High resolution transmission electron microscopy analysis suggests that these are (0001) twins. This work discusses the mechanisms responsible for their formation based on crystallographic analysis and mechanical loading conditions. Specifically, we propose that there are two potential models that can be used to describe twin formation in boron carbide particles. The structural models involve slip in the 1/3[1100] (0110) or 1/3[0110] (0110) planes of C–C–C chains and the appropriate reconfiguration of B–C bonds. Analysis of the loading conditions experienced by the boron carbide particles indicates that local high stress intensity and the presence of a high shear force around the boron carbide particles are two factors that contribute to twin formation.
COMPARISON OF EXPERT AND NOVICE SCAN BEHAVIORS DURING VFR FLIGHT (2001)

A 54-year-old woman presented with subcutaneous nodules and a prior diagnosis of multiple, cutaneous granular-cell tumors. The first case of granular cell tumor was reported in 1854. It remains a rare tumor, which is most commonly seen in women. One-half are usually located in the head and neck region, mostly on the tongue. Approximately one third are cutaneous and 25 percent of the cases occur as multiple lesions.
Care of the Injured Pregnant Patient (1994)

Nursing care of the obstetric patient requires an understanding of normal changes that occur during pregnancy in order to make critical decisions concerning care for her and her infant. Trauma during pregnancy threatens not only the pregnant woman but also her infant. This article reviews the normal physiologic changes relating to pregnancy. It includes a checklist for orthopaedic nurses to use when caring for a pregnant patient.
In vitro T cell responses to a candidate Epstein‐Barr virus vaccine: human CD4<sup>+</sup> T cell clones specific for the major envelope glycoprotein gp340 (1988)

Specific T cell proliferation was observed in short-term blood mononuclear cell cultures set up from Epstein-Barr virus (EBV)-immune individuals and challenged either with UV-irradiated EB virions or with a candidate subunit vaccine preparation, the purified envelope glycoprotein gp340 incorporated into immune stimulating complexes (gp340 iscoms). Limiting dilution culture of the activated T lymphoblasts in interleukin 2-containing medium generated stable CD3+CD4+CD8- T cell clones. Particular clones showing virus-specific proliferation in preliminary screening assays were selected for more detailed study. Three gp340 iscoms-induced clones from EBV-immune donor CG responded specifically to restimulation either with UV-EBV or with purified gp340 iscoms in the presence of autologous antigen-presenting cells (APC). Both T cell-depleted blood mononuclear cells and the EBV-transformed B cell line (treated with Acyclovir to block endogenous gp340 production) could be used for presentation, the latter being the more efficient when gp340 iscoms was the source of antigen. Blocking studies with monoclonal antibodies to HLA class II antigens and experiments using HLA-typed allogeneic APC indicated that all three gp340-specific CG clones were restricted through the HLA-DR2 antigen. One gp340 iscoms-induced clone from another EBV-immune donor, MR, likewise showed gp340-specific proliferation, in this case restricted through a HLA-DR4 antigen. Using HLA-DR-homozygous B cell lines representing the five known DR4 subtypes, efficient presentation of gp340 to this T cell clone was observed with both DR4 Dw4 and DR4 Dw14 antigens. Parallel experiments on one UV-EBV-induced T cell clone from donor MR gave a different pattern of results; these cells appeared to be specific for a virus structural component other than gp340 and to be restricted through an HLA-DP determinant.
Photoassisted Degradation of Dye Pollutants. 8. Irreversible Degradation of Alizarin Red under Visible Light Radiation in Air-Equilibrated Aqueous TiO<sub>2</sub> Dispersions (1999)

Alizarin red undergoes rapid photoassisted decomposition in air-equilibrated aqueous TiO2 dispersions under visible light radiation (λ > 420 nm). Proton NMR, chemical oxygen demand (CODCr), UV−visible, IR, GC−MS, and spin-trapping ESR spectroscopic techniques were employed to obtain details of the photodegradation of alizarin red. Peroxides and carbonyl species are the first intermediates observed during the process. The major component of the peroxides produced is H2O2, and no organoperoxides were detected. We have also confirmed that in addition to CO2 and to smaller carbonyl species the principal intermediate produced is phthalic acid, which is unable to degrade further because it does not absorb the actinic visible light radiation (λ > 420 nm). The photodegradation kinetics are discussed in terms of the Langmuir−Hinshelwood model, a case of saturation type kinetics. A mechanism for the photoassisted degradation of alizarin red mediated by TiO2 particles under visible light radiation is proposed.
Los cuerpos de las mujeres y el cuerpo político católico: Autoridades e identidades en conflicto en España durante las décadas de 1920 y 1930 (1999)

La carta pastoral colectiva de los arzobispos espanoles, en julio de 1926, sobre el comportamiento y la vestimenta de las mujeres revela la preocupacion y la incapacidad de la Iglesia por controlar la apariencia corporal de las mujeres, signo de unos cambios culturales en relacion con el genero unidos a la secularizacion y a las corrientes modernas. Con la perdida de influencia sobre el cuerpo politico en 1931, la Iglesia recurrio a movilizar a sus partidarios y en especial a las mujeres desde una construccion catolica de la feminidad, que no tuvo mas opcion que competir con otras tendencias secularizantes. La victoria de Franco en la guerra civil permitio restaurar desde la fuerza del estado lo que la Iglesia no podia ya realizar por si misma
Porcine Adrenal Adrenocorticotropic Hormone Receptors: Characterization, Changes during Neonatal Development, and Response to a Stressor* (1991)

ACTH receptors were characterized in the porcine adrenal cortex using a biologically active [125I] Tyr23,Phe2,Nle4ACTH(1-38) analog, and a 149,000 X g(av) total particulate tissue preparation. Binding of this labeled ACTH analog to adrenocortical ACTH receptors was demonstrated to be time and temperature dependent, tissue and hormone specific, saturable, reversible, have a binding optimum at pH 7.5, and be dependent on the presence of Ca++. Scatchard analyses of saturation data using the computer program LIGAND indicated a single class of high affinity binding sites [association constant (Ka) = 2.00 +/- 0.25 10(9) M-1)]. Hill plots of saturation data had slopes (b = 0.83 +/- 0.09) that did not differ from 1, and hence also indicated a single class of binding sites. The rate constant of association (k1 = 3.72 +/- 1.19 X 10(8) min-1M-1) was compatible with the known rapidly occurring action of ACTH in pigs in vivo. Kinetic experiments also indicated the ACTH receptors to be of high affinity (4.18 +/- 0.54 X 10(10) M-1; n = 4). Receptor-associated degradation occurring to analog during incubations involved cleavage of the peptide into fragments rather than deiodination and could be partially prevented by use of 0.01% bacitracin. Subsequently, a study was conducted to determine changes in the ability of piglets to respond, in terms of plasma cortisol, to the physiological and psychological stressor of overnight maternal deprivation (MD) at various neonatal ages (days 3-31 of age); to measure age-related and stressor-associated changes in adrenal ACTH receptors; and to associate any changes in adrenal response with changes in ACTH receptors. Plasma cortisol obtained by venipuncture did not vary with age in either control or MD piglets but was elevated by MD (16.98 +/- 2.5 vs. 68.3 +/- 8.2 ng/ml). There was no effect of MD and associated hormonal perturbations on adrenal ACTH receptors. However, there were significant age-related differences in these receptors, with a 1.6-fold increase in concentrations (55.6 +/- 12.0 fmol/mg protein), and a 63% decrease (P less than 0.05) in affinity (4.19 +/- 0.86 x 10(8) M-1) evident at 17 days of age compared with 10 and 24 days of age. The significance of these age-related changes in ACTH receptors for adrenal function remains to be determined; however, it is evident that in neonatal pigs, there is no stress nonresponsive period.
