Transformative art: art as means for long-term neurocognitive change (2012)

Every artwork leads to a unique experience by the observer or participant, may it be sensory, emotional, cognitive, interactive, or spiritual experience. At the neurobiological level, such experiences are manifested as activation of the corresponding neural networks. Neuroscience has demonstrated that experience, in particular repeated experience, can cause a long-term change in the involved brain circuits (experience-dependent plasticity). This review will discuss the molding and transformative aspect of arts, examining how repeated and on-going experience of arts may alter cognitive, emotional, and behavioral patterns as well as their underlying neural circuits. The application of this approach to cognitive training and neuropsychological rehabilitation methods will be addressed as well. In addition, it will be suggested that this approach to art, as a long-term transformative medium, may lead to a novel viewpoint on art and a different approach to its creation. Artists can design artworks that aspire to form, in addition to one-shot influencing experience, on-going experiences which gradually create a lasting change, possibly improving audiences' neuropsychological functions.
A Study Of the Interaction Of DAPI With DNA Containing AT and Non-AT Sequences—Molecular Specificity Of Minor Groove Binding Drugs (1994)

The binding specificity of DAPI to DNA has been probed by analysing its interactions with DNA octamers consisting of different base sequences, which include adenine, guanine, 2-amino adenine and inosine, using molecular mechanics methods. Presence of AT and non-AT base pairs in the immediate vicinity of the binding site, containing AT and non-AT base pairs is also investigated. Results show that DAPI most prefers to bind to homopolymer of AT, and least to the duplex containing alternating GC bases. DAPI interacts with homopolymeric duplexes in two possible orientations related by 180 degrees with nearly same affinity. Affinity of DAPI towards DNA comprising the modified bases, inosine and 2-amino adenine, is in between these extremities. The binding affinity is reduced to some extent by the occurrence of non AT bases flanking the four base paired binding region. An interesting revelation is that one can visualise DAPI to form a hydrogen bond with O2 of cytosine indicating that the 2-amino group of purines does not per se sterically preclude DAPI from residing in the minor groove of B-DNA helix. On the other hand, repulsive nature of electrostatic interactions that prevail at the minor groove consequent to the presence of these sequences contribute decisively in preventing further diffusion of the drug. Thus, electrostatics, rather than hydrogen bonding to bases, seemingly play an important role in determining the specificity of interaction. The retention of drug binders in the minor groove and therefore recognition, is governed by the combined effect of these various forces.
Palmitoyl Carnitine Increases the Transmeningeal Flux of Hydrophilic but Not Hydrophobic Compounds In Vitro (1996)

The mechanism by which palmitoyl carnitine increases transmeningeal flux is unclear but may be a result of palmitoyl carnitine's ability to decrease packing order of lipid bilayers in the arachnoid mater cell membranes. Regardless of the mechanism, palmitoyl carnitine's ability to selectively increase the transmeningeal flux of hydrophilic compounds in vitro offers the possibility of improving the spinal bioavailability of this group of epidurally administered drugs in vivo.
Equivalent-Circuit Models for the Design of Metamaterials Based on Artificial Magnetic Inclusions (2007)

In this paper, we derive quasi-static equivalent-circuit models for the analysis and design of different types of artificial magnetic resonators—i.e., the multiple split-ring resonator, spiral resonator, and labyrinth resonator—which represent popular inclusions to synthesize artificial materials and metamaterials with anomalous values of the permeability in the microwave and millimeter-wave frequency ranges. The proposed models, derived in terms of equivalent circuits, represent an extension of the models presented in a recent publication. In particular, the extended models take into account the presence of a dielectric substrate hosting the metallic inclusions and the losses due to the finite conductivity of the conductors and the finite resistivity of the dielectrics. Exploiting these circuit models, it is possible to accurately predict not only the resonant frequency of the individual inclusions, but also their quality factor and the relative permeability of metamaterial samples made by given arrangements of such inclusions. Finally, the three models have been tested against full-wave simulations and measurements, showing a good accuracy. This result opens the door to a quick and accurate design of the artificial magnetic inclusions to fabricate real-life metamaterial samples with anomalous values of the permeability.
Low-resistance IrMn and PtMn tunnel valves for recording head applications (2001)

We have investigated the use of ultrathin Al2O3 barriers to fabricate low-resistance tunnel-valve sensors suitable for recording heads. Tunnel valves of the type underlayer/(IrMn or PtMn)/CoFe/Al2O3/CoFe/NiFe/Cap layer have been fabricated by magnetron sputtering. Tunnel barriers are formed by Al metal deposition followed by in situ oxidation, and tunnel-junction test devices are built by photolithography with areas down to 1×1 μm2. Specific resistances as low as 13 Ω μm2 with 25% tunnel magnetoresistance have been obtained using Al thicknesses of 6–7 Å.
IVS Tropospheric Parameters - Comparison with DORIS and GPS for CONT02 (2004)

In April 2002 the IVS (International VLBI Service for Geodesy and Astrometry) set up the Pilot Project - Tropospheric Parameters, and the Institute of Geodesy and Geophysics (IGG), Vienna, was put in charge of coordinating the project. Seven IVS Analysis Centers have joined the project and regularly submitted their estimates of tropospheric parameters (wet and total zenith delays, horizontal gradients) for all IVS-R1 mid IVS-R4 sessions since January 1st, 2002. The individual submissions are combined by a two-step procedure to obtain stable, robust and highly accurate tropospheric parameter time series with one hour resolution (internal accuracy: 2-4 ram). Starting with July 2003, the combined tropospheric estimates became operational IVS products. In the second half of October 2002 the VLBI campaign CONT02 was observed with 8 stations participating around the globe. At four of them (Gilmore Creek, U.S.A.; Hartebeesthoek, South Africa; Kokee Park, U.S.A.; Ny-Alesund, Norway) also total zenith delays from DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite) are available and these estimates are compared with those from the IGS (International GPS Service) and the IVS. The distance from the DORIS beacons to the co-located GPS and VLBI stations is around 2 km or less for the four sites mentioned above.
The rotation of polar groups in high polymers (1956)

Abstract The dielectric constant and loss factor of cyanoethylcellulose have been studied as functions of frequency at four temperatures. The unusually high value of the dielectric constant (13.3 at 60 cycles and 25°C.) is attributed to rotation of the CH 2 CN group. Anomalous dispersion in the megacycle region also supports this interpretation. Similar properties are displayed by polyvinyl‐β‐cyanoethyl ether, but allyl cyanide polysulfone gives evidence of steric hindrance.
Intelligent student information system (2003)

This project is aimed at designing the software to manage the students' academic data such as their status (pass, fail, probation, 'cuti khas', dismiss) so that their GPA and CGPA can be generated. This information is useful for students to plan their academic performance in the next semester. The system will also enable the Head of Programs, the Academic Advisors as well as other faculty's management teams to easily simulate the students' study plan through user friendly menu driven interface forms. The system is designed using Visual Basic Programming and Microsoft Access database program.
Healthy Beginnings Plus: An innovative approach to prenatal care (1995)

This article describes an innovative prenatal program developed by the Pennsylvania Depart ment of Public Welfare. The program, Healthy Beginnings Plus, offers an array of educational and counseling services to pregnant women in an effort to improve birth outcomes. The feature element of Healthy Beginnings Plus is the care coordinator, who provides the client with health promotion teaching, home assessments/visitation, and a variety of counseling services. The ar ticle describes the operation of the Healthy Beginnings Plus Program at the Lancaster General Hospital Family Health Service. It further suggests that this full service program may be a cre ative, cost-saving model that other states could replicate to help improve infant outcomes.

Roughness of the silicon (001)/SiO2 interface (1993)

We use synchrotron x-ray diffraction to characterize the roughness of the buried Si(001)/SiO2 interface, for three types of oxide, without modification of the interface. We show that the thermal oxide interface is 0.5±0.1 times as rough as the native oxide interface, suggesting that the oxide growth decreases the roughness slightly. We also measure the roughness of a chemically grown oxide interface.
Ultrasound Image Enhancement Using Structure Oriented Adversarial Network (2018)

In this letter, we aim to develop a deep adversarial despeckling approach to enhance the quality of ultrasound images. Most of the existing approaches target a complete removal of speckle, which produces oversmooth outputs and results in loss of structural details. In contrast, the proposed approach reduces the speckle extent without altering the structural and qualitative attributes of the ultrasound images. A despeckling residual neural network (DRNN) is trained with an adversarial loss imposed by a discriminator. The discriminator tries to differentiate between the despeckled images generated by the DRNN and the set of high-quality images. Further to prevent the developed network from oversmoothing, a structural loss term is used along with the adversarial loss. Experimental evaluations show that the proposed DRNN outperforms the state-of-the-art despeckling approaches in terms of the structural similarity index measure, peak signal to noise ratio, edge preservation index, and speckle region's signal to noise ratio.
Interface characteristics of selective tungsten on silicon using a new pretreatment technology for ULSI application (1997)

The characteristics of selective tungsten film on silicon strongly depend on the surface properties of the underlying substrate. In this work, a new pretreatment process prior to selective tungsten film deposition has been developed. A CF/sub 4//O/sub 2/ mixed plasma modification procedure and a subsequent O/sub 2/ plasma ashing step combine to achieve efficient surface precleaning. The damage and contamination induced by reactive ion etching (RIE) are thus eliminated. Concurrently, a subsequent anhydrous HF cleaning was used to remove the native oxide on silicon as well as to obtain a fluorine-passivated silicon surface which can avoid reoxidation during the transport of wafers. This new pretreatment technology produces tungsten films that retain superior physical properties within the aspects of deposition rate, film morphology, and selectivity. Also, excellent interface characteristics with low silicon consumption, low contact resistance, low contact leakage current, and fewer impurities of fluorine, oxygen, and carbon within the interfacial region are obtained.
Production of Titanium Deposits by Cold Gas Dynamic Spray (2005)

Abstract Over the past five years, interest in cold gas dynamic spraying (CGDS) has increased substantially. Considerable effort has been devoted to process development and optimization for low melting point metals such as copper and aluminium. This paper will describe work undertaken to expand the understanding of deposition of titanium by cold spray methods. CGDS deposits have been produced from commercially pure Ti. Using room temperature helium gas, a range of processing conditions, powder size ranges, substrates and substrate preparation methods have been employed to study their impact on deposition of powders. Scanning electron microscopy has been employed to examine deposit microstructures, and microhardness testing of deposits has been conducted. Samples for pull-off bond strength test have been prepared from a number of the more promising sets of parameters and adhesive strengths have been determined. Computational estimates of gas velocity and in-flight particle velocity have been made focusing specifically on the influence that these factors have on the process deposition efficiency. Differences will be discussed in terms of powder feedstock characteristics and the underlying physical and mechanical properties of the powders and substrates.
TSG‐6 expression in human articular chondrocytes: Possible implications in joint inflammation and cartilage degradation (1996)

Chondrocytes are a source of TSG-6 which may play a role in cartilage remodeling and joint inflammation.
Efficient conversion of light from sparse laser arrays into single-lobed far field using phase structures (2008)

An efficient beam-combining technique based on aperture filling is introduced to direct virtually all the energy of a mutually coherent laser array to the far-field main lobe. A comparison between this method and the Dammann grating method for beam superposition reveals the connection between the two and suggests specific applications for each.
Leupeptin, a Protease Inhibitor, Decreases Protein Degradation in Normal and Diseased Muscles (1978)

The protease inhibitor leupeptin decreases protein degradation in rat skeletal and cardiac muscle incubated in vitro, while protein synthesis remains unaltered. Leupeptin also lowers protein breakdown in denervated rat muscles and affected muscles from mice with hereditary muscular dystrophy. Leupeptin may thus be useful in retarding tissue atrophy. Since homogenates of leupeptin-treated muscles had decreased cathepsin B activity, this lysosomal protease may play a role in protein turnover in normal and diseased muscles.
Lossless optical modulation in a silicon waveguide using stimulated Raman scattering (2005)

In this paper we describe a new modulation scheme using stimulated Raman scattering in conjunction with a reverse biased p-i-n diode embedded in a silicon waveguide. We show optical modulation of a weak probe beam by modulating the reverse bias voltage of the silicon waveguide excited by a strong pump beam. The probe beam modulation is due to the two-photon absorption-induced carrier density modulation in the waveguide. By tuning the probe wavelength to the Stokes wavelength, we demonstrate for the first time a lossless optical modulator in silicon with modulation speeds up to 80-MHz.
Abstract 4239: Pterostilbene, a natural polyphenol, elicits full protection against ultraviolet B radiation-induced skin carcinogenesis: Preclinical studies (2011)

Abstract Solar radiation exposure is the chief cause of nonmelanoma (i e, basal cell and squamous cell) skin cancer, and it is also a prime factor in the etiology of cutaneous melanoma The cancer-causing effects of ultraviolet (UV) radiation on the skin are mainly produced by UV-B radiation in the 290- to 320-nm range, the same range that produces burning in human skin (erythema) UV-B exposure can damage DNA and be immunosuppressive Thus, and considering the alarming numbers of skin cancers being diagnosed around the world, it is increasingly evident the need of effective protection from UV radiation Resveratrol (trans-3,5,4′-trihydroxystilbene; RES) is a phytoalexin present in a wide variety of plant species, where its synthesis is induced by stress conditions The cancer chemopreventive activity of RES was first reported by Jang et al [Science 275, 218 – 220 (1997)] in a model of skin carcinogenesis where topic administration of this polyphenol inhibited multistage mouse skin carcinogenesis Equally promising action is exerted by resveratrol analogues, mainly pterostilbene (3,5-dimethoxy-4′-hydroxy-trans-stilbene: PTER), which shows a higher half-life in vivo and more potent anticancer effects in vivo than RES Our aim was to compare the anticancer effects of RES and PTER in UVB-induced mouse skin carcinogenesis In our experiments, Female SKH-1 hairless mice were irradiated with UVB (180 mJ/cm2; 3 doses/week; for a total of 30 weeks) 20 min after or before the topical administration of liposomes containing a total of 10 μmol of RES or PTER/mice (aprox 2 5 μmol/cm2 of skin) This long-term UVB administration reproduces, in an animal model, which are the consequences in humans of receiving chronic UVB radiations We observed that pretreatment of the skin with PTER resulted in a dramatic reduction in UVB-induced skin tumorigenesis (90 % of tumor free-mice at the end of treatment, n=20; P&lt;0 01), whereas all RES-treated mice showed carcinomas (0 % of tumor free-mice on the 30th week, n=20) Molecular mechanisms involved in this strong anticancer effect elicited by Pter (as compared with RES) suggest differences in prevention of DNA mutagenesis, and protein and lipid oxidation Our results indicate that PTER can be used efficiently in the prevention of skin carcinogenesis induced by solar radiation.

Fast link prediction for large networks using spectral embedding (2017)

Many link prediction algorithms require the computation of a similarity metric on each vertex pair, which is quadratic in the number of vertices and infeasible for large networks. We develop a class of link prediction algorithms based on a spectral embedding and the k closest pairs algorithm that are scalable to very large networks. We compare the prediction accuracy and runtime of these methods to existing algorithms on several large link prediction tasks. Our methods achieve comparable accuracy to standard algorithms but are significantly faster.

Nitrides of Chromium and Chromium-Titanium Alloys (1955)

Some electrical properties of nitrided Cr and nitrided Cr‐Ti films are presented. Films of chromium and chromium‐titanium alloys, deposited on ceramic bases by vacuum‐evaporation methods, were nitrided to form electrical resistance elements. By varying thickness and nitriding conditions, the electrical properties of the films can be varied. Materials can be prepared with temperature coefficients of resistance less than 0.01%/°C. Resistors with resistances of from several hundred to several million ohms can be made. Resistance to environmental attack and other properties are also described.
Controlled p doping of the hole-transport molecular material N,N′-diphenyl-N,N′-bis(1-naphthyl)-1,1′-biphenyl-4,4′-diamine with tetrafluorotetracyanoquinodimethane (2003)

We investigate p-type doping of the hole-transport organic molecular material N,N′-diphenyl-N,N′-bis(1-naphthyl)-1,1′-biphenyl-4,4′-diamine (α-NPD) with tetrafluorotetracyanoquinodimethane (F4-TCNQ) using direct and inverse photoemission spectroscopy, contact potential difference measurements, and in situ current–voltage (I–V) measurements. The close match between the ionization energy of α-NPD and the electron affinity of F4-TCNQ leads to an efficient charge transfer between highest occupied molecular orbital of the host and lowest occupied molecular orbital of the dopant. The Fermi level moves down towards the valence states by 0.62 eV in the 0.5% doped film with respect to the undoped film, and a narrow space charge layer (∼60 Å) forms at the interface with Au. Hole injection in the doped devices increases by several orders of magnitude due to tunneling through the depletion region. The large relaxation energy of the ionized α-NPD molecule limits the movement of the Fermi level and, ultimately, the hole injection.
Exponential approach to estimate the Curie-temperature depth (2010)

To utilize the power density spectra of magnetic anomaly is a classical routine in the estimation of the Curie-temperature depth. Many applications of this technique are encountered in the geophysical literature in spite of the difficulty arising from the selection of the points for the slope of the straight line on the power density graph. In this study, a different approach for the estimation of the Curie-temperature depth from magnetic data was introduced. It is based on the analytical solution of the exponential equations obtained from the Fourier transformation of the magnetic data. The proposed approach has been tested on the synthetic magnetic anomalies originated by single prism and multi-prisms. According to encouraging test results, this technique was also treated on the field data which were studied to estimate the top and bottom depths by using power spectra and optimization solutions.
