Strong magnetic pair breaking in Mn-substituted<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mi mathvariant="normal">Mg</mml:mi><mml:msub><mml:mi mathvariant="normal">B</mml:mi><mml:mn>2</mml:mn></mml:msub></mml:mrow></mml:math>single crystals (2006)

Magnetic ions (Mn) were substituted in $\mathrm{Mg}{\mathrm{B}}_{2}$ single crystals resulting in a strong pair-breaking effect. The superconducting transition temperature, ${T}_{c}$, in ${\mathrm{Mg}}_{1\ensuremath{-}x}{\mathrm{Mn}}_{x}{\mathrm{B}}_{2}$ has been found to be rapidly suppressed at an initial rate of $10\phantom{\rule{0.3em}{0ex}}\mathrm{K}∕%\mathrm{Mn}$, leading to a complete suppression of superconductivity at about 2% Mn substitution. This reflects the strong coupling between the conduction electrons and the $3d$ local moments, predominantly of magnetic character, since the nonmagnetic ion substitutions, e.g., with Al or C, suppress ${T}_{c}$ much less effectively (e.g., $0.5\phantom{\rule{0.3em}{0ex}}\mathrm{K}∕%\mathrm{Al}$). The magnitude of the magnetic moment ($\ensuremath{\simeq}1.7\phantom{\rule{0.3em}{0ex}}{\ensuremath{\mu}}_{B}$ per Mn), derived from normal state susceptibility measurements, uniquely identifies the Mn ions to be divalent, and to be in the low-spin state $(S=1∕2)$. This has been found also in x-ray absorption spectroscopy measurements. Isovalent ${\mathrm{Mn}}^{2+}$ substitution for ${\mathrm{Mg}}^{2+}$ mainly affects superconductivity through spin-flip scattering reducing ${T}_{c}$ rapidly and lowering the upper critical field anisotropy ${H}_{c2}^{ab}∕{H}_{c2}^{c}$ at $T=0$ from 6 to 3.3 ($x=0.88%$ Mn), while leaving the initial slope $\mathrm{d}{H}_{c2}∕\mathrm{d}T$ near ${T}_{c}$ unchanged for both field orientations.
Economic Effects of Clinical Chicken Anemia Agent Infection on Profitable Broiler Production (1992)

An outbreak of anemia dermatitis syndrome caused by chicken anemia agent (CAA) occurred in 15 broiler flocks. An average of 29% of chickens in these flocks were derived from a common breeder flock. The breeder flock had no antibody to CAA at 20 weeks of age but had seroconverted by 31 weeks. Diseased broiler flocks were derived from eggs laid by the breeder flock between 25 and 30 weeks of age. CAA infection in the breeder flock was subclinical, with no apparent effects on mortality or performance. A strategic program of therapeutic and/or prophylactic antibiotic therapy was begun in affected broiler flocks as soon as the disease was diagnosed. Nevertheless, when the cost of therapy was taken into account, affected broiler flocks had a net income 17.3% to 19.6% lower than normal flocks. Average bird weights were 3.3% to 3.5% lower in affected flocks than in unaffected flocks, and affected flocks had a significantly greater proportion of lighter birds. Average mortality in affected flocks was 2.0% to 2.3% higher than in normal flocks, with peak mortality occurring in the third week of life. There was no apparent effect on feed-conversion ratio.
Phototransistor arrays of simplified design (1971)

Bacterial endophthalmitis after small-incision cataract surgery (2003)

The findings suggest that a temporal corneal incision may lead to an increased risk of postoperative endophthalmitis and that the IOL material does not affect the incidence of this complication.
Tunable, narrow-band light emission from size-selected Si nanoparticles produced by pulsed-laser ablation (2003)

We have demonstrated narrow-band visible light emission from size selected silicon nanoparticles (np-Si), with a wavelength controlled by size tuning. The np-Si were synthesized by pulsed-laser ablation of a silicon single-crystal target in high-purity He background gas. A postannealing process improved morphology and crystallinity. Using a differential mobility analyzer, nanoparticles were classified with a diameter tunable from 3 to 6 nm. Monodispersed np-Si deposited on substrate exhibited a sharp photoluminescence band. The energy of this band increased from 1.34 to 1.79 eV with decrease in particle size, and narrowed to approximately 0.22 eV full width at half maximum due to highly resolved size-selection and improvement in crystallinity. The results suggest that tunable, narrow-band light emitting np-Si produced by gas phase synthesis have good possibilities for application as optoelectronic devices.
An Analytical Model for Multi-layer and Multi-electrode Piezoelectric Ceramic Actuators (2006)

This paper develops an analytical model for multielectrodes in multi-layered piezoelectric actuators. The electrodes are vertical to and terminated at the edges of the medium. Electroelastic field concentrations ahead of electrodes in the multilayer piezoelectric actuators are examined. By considering a representative unit in real multilayers, the problem is formulated directly in terms of the electric potential between the electrode tips, results in a system of singular integral equations in which the unknown function is the electric potential. Effects of electrode spacing and piezoelectric coupling on the singular electroelastic fields at the electrode tips are investigated. Closed-form expressions for the electromechanical field near the electrode tips are given.
Crystal Structure of Human Estrogen-related Receptor α in Complex with a Synthetic Inverse Agonist Reveals Its Novel Molecular Mechanism (2007)

Inverse agonists of the constitutively active human estrogen-related receptor alpha (ERRalpha, NR3B1) are of potential interest for several disease indications (e.g. breast cancer, metabolic diseases, or osteoporosis). ERRalpha is constitutively active, because its ligand binding pocket (LBP) is practically filled with side chains (in particular with Phe(328), which is replaced by Ala in ERRbeta and ERRgamma). We present here the crystal structure of the ligand binding domain of ERRalpha (containing the mutation C325S) in complex with the inverse agonist cyclohexylmethyl-(1-p-tolyl-1H-indol-3-ylmethyl)-amine (compound 1a), to a resolution of 2.3A(.) The structure reveals the dramatic multiple conformational changes in the LBP, which create the necessary space for the ligand. As a consequence of the new side chain conformation of Phe(328) (on helix H3), Phe(510)(H12) has to move away, and thus the activation helix H12 is displaced from its agonist position. This is a novel mechanism of H12 inactivation, different from ERRgamma, estrogen receptor (ER) alpha, and ERbeta. H12 binds (with a surprising binding mode) in the coactivator groove of its ligand binding domain, at a similar place as a coactivator peptide. This is in contrast to ERRgamma but resembles the situation for ERalpha (raloxifene or 4-hydroxytamoxifen complexes). Our results explain the novel molecular mechanism of an inverse agonist for ERRalpha and provide the basis for rational drug design to obtain isotype-specific inverse agonists of this potential new drug target. Despite a practically filled LBP, the finding that a suitable ligand can induce an opening of the cavity also has broad implications for other orphan nuclear hormone receptors (e.g. the NGFI-B subfamily).
Field evaluation of pyriproxyfen and spinosad mixture for the control of insecticide resistant Aedes aegypti in Martinique (French West Indies) (2010)

The mixture of pyriproxyfen and spinosad kills larvae and pupae giving it a broader range of action than either insecticide. This mixture could preserve the utility of both insecticides in public health programs.
Binding of a histidine-rich peptide to<i>Porphyromonas gingivalis</i> (1991)

Porphyromonas gingivalis 381 cells were incubated with 125I-histidine-rich polypeptide (histatin) 5 in the presence or absence of unlabeled histatin 5, to evaluate the histatin-binding capacity of the cells. The binding of histatin 5 was rapid, reversible, saturable and specific. The number of histatin 5-binding sites per cell was 3,600, and the dissociation constant (Kd) was in the order of 10(-6) M. These findings suggest that histatin interacts with certain bacterial cells through specific binding sites on their surface, and will allow the development of a histatin radioreceptor assay.
Skin in pulmonary tuberculosis. (1994)

ABSTRACT: Dermatological changes were recorded in 344 (18.4 percent) out of 1866 male patients (18 to 63 years) of pulmonary tuberculosis from June 1991 to May 1993. Cutaneous tuberculosis was recorded in 0.2 percent patients. The commonest cutaneous (5.8 percent) were drug eruptions (maculopapular 3.6 percent acneiform 1.0 percent, pruitus 0.6 percent, urticaria 0.4 percent and vasculitis 0.2 percent), followed by fungal infections 3.5 percent, viral infections 1.9 percent, eczema/dermatitis 1.5 percent, scabies 1.2 percent, STD 0.8 percent, pyodermas 0.6 percent, HIV infection (PGL) 0.4 percent autoimmune disorders, reactions to mechanical trauma, leprosy and alopecia areata 0.3 percent each; nutritional disorders, clubbing of fingers and acne vulgaris 0.2 percent each; papulosqamous disorders, vitiligo, macular amyloidosis and hyperhidrosis were observed in 0.1 percent or less. 35.1 percent had far advances, 50.6 percent had moderately advanced and 14.3 percent had minimal pulmonary lesions on radiological examination in those having cutaneous lesions. Sputum for AFB was positive in more than half (52.6 percent).
An atomic layer deposition passivated Surface Acoustic Wave sensor for bacterial biofilm growth monitoring (2012)

This thesis reports for the first time the design, fabrication, and testing of a reusable Surface Acoustic Wave (SAW) sensor for biofilm growth monitoring. Bacterial biofilms cause severe infections, and are often difficult to remove without an invasive surgery. Thus, their detection at an early stage is critical for effective treatments. A highly sensitive SAW sensor for biofilm growth monitoring was fabricated by depositing a high quality zinc oxide (ZnO) piezoelectric thin film by pulsed laser deposition (PLD). The sensor was successfully passivated by aluminum oxide (Al2O3) using Atomic Layer Deposition (ALD) to prevent ZnO damage from long term media contact. The sensor was reusable over multiple biofilm formation experiments using the ALD Al2O3 passivation and an oxygen plasma biofilm cleaning method. The SAW sensor was studied with Escherichia coli biofilm growth in Lysogeny Broth (LB) and in 10% Fetal Bovine Serum (FBS) as a simulated an in vivo environment. A multiple MHz level resonant frequency shift measured at the output of the SAW sensor in both LB and 10% FBS corresponded to the natural biofilm growth progression. These repeatable E. coli biofilm growth monitoring results validate the novel application of a SAW sensor for future implantable biofilm sensing applications.
LccA, an Archaeal Laccase Secreted as a Highly Stable Glycoprotein into the Extracellular Medium by <i>Haloferax volcanii</i> (2009)

Laccases couple the oxidation of phenolic compounds to the reduction of molecular oxygen and thus span a wide variety of applications. While laccases of eukaryotes and bacteria are well characterized, these enzymes have not been described in archaea. Here, we report the purification and characterization of a laccase (LccA) from the halophilic archaeon Haloferax volcanii. LccA was secreted at high levels into the culture supernatant of a recombinant H. volcanii strain, with peak activity (170 +/- 10 mU.ml(-)(1)) at stationary phase (72 to 80 h). LccA was purified 13-fold to an overall yield of 72% and a specific activity of 29.4 U.mg(-)(1) with an absorbance spectrum typical of blue multicopper oxidases. The mature LccA was processed to expose an N-terminal Ala after the removal of 31 amino acid residues and was glycosylated to 6.9% carbohydrate content. Purified LccA oxidized a variety of organic substrates, including bilirubin, syringaldazine (SGZ), 2,2,-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and dimethoxyphenol (DMP), with DMP oxidation requiring the addition of CuSO(4). Optimal oxidation of ABTS and SGZ was at 45 degrees C and pH 6 and pH 8.4, respectively. The apparent K(m) values for SGZ, bilirubin, and ABTS were 35, 236, and 670 muM, with corresponding k(cat) values of 22, 29, and 10 s(-)(1), respectively. The purified LccA was tolerant of high salt, mixed organosolvents, and high temperatures, with a half-life of inactivation at 50 degrees C of 31.5 h.
A visual query system implementing a temporal object-oriented model with roles on a relational database (2002)

The use of a temporal data model to represent an application does not require the existence of a specific database to implement this model. Already-existing commercial databases can be used with an appropriate mapping between data models. When this approach is used, the possibility of stating queries in the original data model is also provided. This paper represents a visual query system for the TF-ORM (Temporal Functionality in Objects-with-Roles Model) data model, which is a temporal object-oriented model with roles. The VQS (Visual Query System) TF-ORM is an environment for information retrieval. Some of its available properties are: visual representation of temporal operators, different level-of-detail definitions when browsing in a graphic scheme, query storage for later use, and the possibility of representing a textual query in a visual way and vice-versa. The TF-ORM model is implemented in a relational database which uses the SQL language for information retrieval. The queries, expressed in the TF-ORM language, are translated into the relational database query language.
Tellurite: history, oxidative stress, and molecular mechanisms of resistance (2009)

The perceived importance of tellurium (Te) in biological systems has lagged behind selenium (Se), its lighter sister in the Group 16 chalcogens, because of tellurium's lower crustal abundance, lower oxyanion solubility and biospheric mobility and the fact that, unlike Se, Te has yet to be found to be an essential trace element. Te applications in electronics, optics, batteries and mining industries have expanded during the last few years, leading to an increase in environmental Te contamination, thus renewing biological interest in Te toxicity. This chalcogen is rarely found in the nontoxic, elemental state (Te(0)), but its soluble oxyanions, tellurite (TeO(3)(2-)) and tellurate (TeO(4)(2-)), are toxic for most forms of life even at very low concentrations. Although a number of Te resistance determinants (Tel) have been identified in plasmids or in the bacterial chromosome of different species of bacteria, the genetic and/or biochemical basis underlying bacterial TeO(3)(2-) toxicity is still poorly understood. This review traces the history of Te in its biological interactions, its enigmatic toxicity, importance in cellular oxidative stress, and interaction in cysteine metabolism.
Characterization of Thermal Decomposition Products of Cerium Acetate by High Temperature FTIR Spectroscopy (2010)

In the present work, thermal decomposition of cerium(III) acetate hydrate (Ce(CH3CO2)3·1.5H2O) was studied in argon gas atmosphere by using thermogravimetric-differential thermal analysis techniques (TG-DTA) and in-situ High Temperature FTIR Spectroscopy technique (HT-FTIR). The obtained FTIR results were combined with the results of performed TG/DTA experiments in the present work and the literature data. A good agreement between the thermal analyses and FTIR results was found, and possible decomposition mechanism is discussed.

16.1: <i>Invited Paper</i> : A Novel Outdoor Readability of Portable TFT‐LCD with AFFS Technology (2006)

Abstract Recently, we have developed advanced fringe field switching (AFFS) technology with a novel outdoor readability, super high CR and high transmittance that obtained from a new electro‐optical design rule by optimization of LC electrodynamics and precise control of polarization light without transflective resin technology. Our new device in 12.1″ XGA has shown the transmittance over 8%, surface reflectance under 0.2%, hardness over 4H, outdoor visibility (image quality, color representation) better than the transflective LCD, contrast ratio over 800:1 and viewing angle over 180°/180°, respectively.
Particle Filter with Novel Nonlinear Error Model for Miniature Gyroscope-Based Measurement While Drilling Navigation (2016)

The derivation of a conventional error model for the miniature gyroscope-based measurement while drilling (MGWD) system is based on the assumption that the errors of attitude are small enough so that the direction cosine matrix (DCM) can be approximated or simplified by the errors of small-angle attitude. However, the simplification of the DCM would introduce errors to the navigation solutions of the MGWD system if the initial alignment cannot provide precise attitude, especially for the low-cost microelectromechanical system (MEMS) sensors operated in harsh multilateral horizontal downhole drilling environments. This paper proposes a novel nonlinear error model (NNEM) by the introduction of the error of DCM, and the NNEM can reduce the propagated errors under large-angle attitude error conditions. The zero velocity and zero position are the reference points and the innovations in the states estimation of particle filter (PF) and Kalman filter (KF). The experimental results illustrate that the performance of PF is better than KF and the PF with NNEM can effectively restrain the errors of system states, especially for the azimuth, velocity, and height in the quasi-stationary condition.
Enhancement of Vancomycin Activity against Biofilms by Using Ultrasound-Targeted Microbubble Destruction (2011)

Treating biofilm infections on implanted medical devices is formidable, even with extensive antibiotic therapy. The aim of this study was to investigate whether ultrasound (US)-targeted microbubble (MB) destruction (UTMD) could enhance vancomycin activity against Staphylococcus epidermidis RP62A biofilms. Twelve-hour biofilms were treated with vancomycin combined with UTMD. The vancomycin and MB (SonoVue) were used at concentrations of 100 μg/ml and 30% (vol/vol), respectively, in studies in vitro. After US exposure (0.08 MHz, 1.0 W/cm(2), 50% duty cycle, and 10-min duration), the biofilms were cultured at 37 °C for another 12 h. The results showed that many micropores were found in biofilms treated with vancomycin combined with UTMD. Biofilm densities (A(570) values) and the viable counts of S. epidermidis recovered from the biofilm were significantly decreased compared with those of any other groups. Furthermore, the highest percentage of dead cells was found, using confocal laser scanning microscopy, in the biofilm treated with vancomycin combined with UTMD. The viable counts of bacteria in biofilms in an in vivo rabbit model also confirmed the enhanced effect of vancomycin combined with UTMD. UTMD may have great potential for improving antibiotic activity against biofilm infections.
Electromagnetic Propagation Logging: Advances in Technique and Interpretation (1980)

ABSTRACT The Electromagnetic Propagation Tool (EPT*) is a downhole microwave instrumentation device which channels 1.1 GHz energy into the formation and measures the travel time and attenuation of the microwave signal as it propagates through the invaded zone. The relevant electromagnetic field theory, the basic measurement technique, and the tool block diagram are reviewed. The present interpretation techniques are then discussed, followed by several log examples which show the utility of the EPT. Specifically, the EPT-derived porosity, when compared with neutron/density porosity, allows one to distinguish between hydrocarbon-bearing and water-bearing zones in formations having varying lithologies and water salinities.
Augmented LSTM Framework to Construct Medical Self-Diagnosis Android (2016)

Given a health-related question (such as "I have a bad stomach ache. What should I do?"), a medical self-diagnosis Android inquires further information from the user, diagnoses the disease, and ultimately recommend best solutions. One practical challenge to build such an Android is to ask correct questions and obtain most relevant information, in order to correctly pinpoint the most likely causes of health conditions. In this paper, we tackle this challenge, named "relevant symptom question generation": Given a limited set of patient described symptoms in the initial question (e.g., "stomach ache"), what are the most critical symptoms to further ask the patient, in order to correctly diagnose their potential problems? We propose an augmented long short-term memory (LSTM) framework, where the network architecture can naturally incorporate the inputs from embedding vectors of patient described symptoms and an initial disease hypothesis given by a predictive model. Then the proposed framework generates the most important symptom questions. The generation process essentially models the conditional probability to observe a new and undisclosed symptom, given a set of symptoms from a patient as well as an initial disease hypothesis. Experimental results show that the proposed model obtains improvements over alternative methods by over 30% (both precision and mean ordinal distance).
