LTE Handover Parameters Optimization Using Q-Learning Technique (2018)

Optimization of the LTE network is crucial to obtain the best performance. The handover margin (HOM) and time to trigger (TTT) should be chosen so that the system will have minimum number of handovers per user per second, minimum system delay, and maximum throughput. In this paper a new handover optimization algorithm for long term evolution (LTE) network based on Q-learning optimization is presented. The proposed algorithm operates by testing different values of HOM and TTT then observes the output performance corresponding to the values of these parameters, and it eventually selects the values that produce the best performance. The proposed handover optimization technique is evaluated and compared to previous work. Q-learning achieves minimum average number of handover per user and also has maximum throughput than the fuzzy logic optimization technique.

Highly transparent and nanostructured nickel oxide (NiO) films through pulsed laser deposition are introduced for efficient CH3 NH3 PbI3 perovskite solar cells. The (111)-oriented nanostructured NiO film plays a key role in extracting holes and preventing electron leakage as hole transporting material. The champion device exhibits a power conversion efficiency of 17.3% with a very high fill factor of 0.813.
Robust Estimation of Large Surface-Consistent Residual Statics (2006)

Surface-consistent residual static correction is applied to land data on a routine basis. However, if the statics are large, conventional methods often break down due to, among other reasons, the difficulty to construct a good pilot trace. We developed a large static correction method that constructs the pilot trace by a local robust L1-norm inversion at each CDP location. The local inversion calculates the relative time shifts of the traces within a CDP gather by minimizing the trace-to-trace time difference. A pilot trace is obtained by stacking the CDP gather after aligning the reflectors by applying the time shifts to the traces. Finally, a global L1-norm inversion resolves the source and receiver statics from the time shifts of traces of all CDP gathers relative to their pilot traces. The method is demonstrated with synthetic and real data examples.

Sodeisha Sculptural Ceramics: Digitalization and VR Interaction (2019)

This demonstration presents the development of a virtual reality (VR) research project for the VR interaction and digitization of “Sodeisha Sculptural Ceramics”, a transmedia approach showcases photogrammetry scanned Japanese ceramic artworks in an educational and public VR exhibition setting. The early prototype has involved the photogrammetry scanning of 10 sculptural ceramic works of art. These works were created by the innovative Japanese post-war artist group, known as ‘Sodeisha’. Newcastle Art Gallery holds one of the largest collections of Sodeisha ceramics outside of Japan and recently featured the collection in a large-scale exhibition titled SODEISHA: connected to Australia from March – May 2019. The audience used controllers to interact with objects in a virtual environment, with the option of seeing a pair of VR hands or full VR arms.
Transmit Power Control for Secondary Use in Environments with Correlated Shadowing (2011)

In this paper we propose a general model to estimate the maximum allowed transmit power of a secondary node based on the measured signal from the primary transmitter that is willing to share its downlink spectrum. The transmit power should satisfy primary constraints related to the minimum required Signal to Interference and Noise Ratio (SINR) of its users. The model can be used by secondary nodes whether or not they have full knowledge about the correlation between the different path losses. Simulation results have shown the high impact of the level of correlation on the performance of both primary and secondary users.
Molecular basis for lack of expression of HLA class I antigens in human small-cell lung carcinoma cell lines (1996)

HLA class I molecules present antigenic peptides to cytotoxic T lymphocytes and thus play an important role in immune surveillance of cells infected with virus or altered by malignant transformation. Immunochemical studies have demonstrated a marked deficiency or lack of expression of class I molecules on the surface of many different types of tumor cells. It is likely that this allows these cells to escape immune surveillance. In the present study, we examined the molecular basis for lack of expression of class I antigens in small-cell lung carcinoma cell lines. Our results demonstrate that these cell lines also lacked products of MHC-encoded proteasome subunit LMP2 and the putative peptide transporter TAP1. In contrast, LMP7 and TAP2 genes were expressed in these cell lines. Pulse-chase experiments showed that class I molecules were unstable and thus not transported to the cell surface from endoplasmic reticulum. Our results suggest that antigenic peptides were not available for binding to class I alpha chains due to lack of TAP1 and LMP2 gene products. Investigations of the regulatory mechanisms of TAP1 and LMP2 genes showed that the tumor cells lacked trans -regulatory nuclear protein(s), which binds to the interferon-gamma (IFN-gamma) response element (ISRE) in the TAP1, LMP2 bidirectional intergenic promoter. Treatment of tumor cells with IFN-gamma induced ISRE-binding nuclear protein(s) and resulted in expression of TAP1 and LMP2 genes with a concomitant increase in cell-surface expression of class I molecules. Our data provide credence for a role of TAP and LMP genes in immune response.
Physician Perspectives Regarding Pneumococcal Conjugate Vaccine (2002)

PCV has been widely accepted by physicians in both Rochester and Nashville. However, many physicians delayed introducing the vaccine for reasons that were ultimately related to financial considerations. For privately insured patients, delays were related to when coverage for PCV was added to benefit packages. For patients who receive publicly purchased vaccine via the VFC program, delays were related to availability of the vaccine through the VFC program. In addition, after the introduction of PCV, some physicians began delaying the administration of other vaccines because of the need to give multiple vaccinations simultaneously. Although lack of insurance or VFC coverage and concerns about multiple simultaneous injections may somewhat delay the initial use of newly recommended vaccines, physicians rapidly begin to provide new vaccines that they believe to be beneficial once those vaccines are incorporated into existing payment mechanisms.
Dimensionality reducing displays in cell image analysis. (1978)

The paper discusses the problem of representation of multivariate cell data sets in two dimensions such that the essence of the situation as represented by the multivariate feature space is preserved. A corresponding projectional technique has been developed and illustrated on a set of five different cell types of ectocervical cells, including normal and carcinoma cells.
Local symmetry of copper sites inLa2−xSrxCuO4 (1991)

Nuclear quadrupole and magnetic resonances of copper ions in ${\mathrm{La}}_{1.84}$${\mathrm{Sr}}_{0.16}$${\mathrm{CuO}}_{4}$ have been performed at temperatures between 300 and 5 K. The analysis of the spectra shows that there are two electronically distinct copper sites for which the symmetry of the electric-field-gradient tensors is uniaxial with the principal axis along the crystal c axis. This result constrains possible structural models.

Development and validation of an RP‐HPLC method for quantitative determination of vanillin and related phenolic compounds in Vanilla planifolia (2007)

A simple and fast method was developed using RP-HPLC for separation and quantitative determination of vanillin and related phenolic compounds in ethanolic extract of pods of Vanilla planifolia. Ten phenolic compounds, namely 4-hydroxybenzyl alcohol, vanillyl alcohol, 3,4-dihydroxybenzaldehyde, 4-hydroxybenzoic acid, vanillic acid, 4-hydroxybenzaldehyde, vanillin, p-coumaric acid, ferulic acid, and piperonal were quantitatively determined using ACN, methanol, and 0.2% acetic acid in water as a mobile phase with a gradient elution mode. The method showed good linearity, high precision, and good recovery of compounds of interest. The present method would be useful for analytical research and for routine analysis of vanilla extracts for their quality control.
Anti-CD3ε mAb improves thymic architecture and prevents autoimmune manifestations in a mouse model of Omenn syndrome: therapeutic implications (2012)

Omenn syndrome (OS) is an atypical primary immunodeficiency characterized by severe autoimmunity because of activated T cells infiltrating target organs. The impaired recombinase activity in OS severely affects expression of the pre-T-cell receptor complex in immature thymocytes, which is crucial for an efficient development of the thymic epithelial component. Anti-CD3ε monoclonal antibody (mAb) treatment in RAG2(-/-) mice was previously shown to mimic pre-TCR signaling promoting thymic expansion. Here we show the effect of anti-CD3ε mAb administration in the RAG2(R229Q) mouse model, which closely recapitulates human OS. These animals, in spite of the inability to induce the autoimmune regulator, displayed a significant amelioration in thymic epithelial compartment and an important reduction of peripheral T-cell activation and tissue infiltration. Furthermore, by injecting a high number of RAG2(R229Q) progenitors into RAG2(-/-) animals previously conditioned with anti-CD3ε mAb, we detected autoimmune regulator expression together with the absence of peripheral immunopathology. These observations indicate that improving epithelial thymic function might ameliorate the detrimental behavior of the cell-autonomous RAG defect. Our data provide important therapeutic proof of concept for future clinical applications of anti-CD3ε mAb treatment in severe combined immunodeficiency forms characterized by poor thymus function and autoimmunity.
Studies on Abscisic Acid (1970)

Oxidation of 2-cis-α-ionylidene-ethanol (II) with active MnO2 afforded a mixture of 2-cis and 2-trans-α-ionylideneacetaldehydes (III and IV). Reduction of methyl epoxy-α- and -β-ionylideneacetates (Vb, Xb XXIb and XXIIb) with LiAlH4 gave the diols (VI, XI, XXIII and XXIV). The Wittig reaction of the hydroxyketones (XIII and XVIII) with carb-ethoxymethylenetriphenylphosphorane, followed by alkaline hydrolysis, yielded 5-(1'-and 2'-hydroxy-2', 6', 6'-trimethyl-l'-cyclohexyl)-3-methylpentadienoic acids (XIVa, XVa, XIXa and XXa). The reaction of α-cyclocitrylideneacetaldehyde (XXVII) and dihydro-a-ionone (XXXIII) with carbethoxymethylenetriphenylphosphorane afforded ethyl 3-demethyl-α-ionyli-deneacetate (XXVIIIb) and ethyl dihydro-α-ionylideneacetates (XXXIVb and XXXVb). Physiological activities of the above synthesized compounds on rice seedlings were examined.
Register promotion by sparse partial redundancy elimination of loads and stores (1998)

An algorithm for register promotion is presented based on the observation that the circumstances for promoting a memory location's value to register coincide with situations where the program exhibits partial redundancy between accesses to the memory location. The recent SSAPRE algorithm for eliminating partial redundancy using a sparse SSA representation forms the foundation for the present algorithm to eliminate redundancy among memory accesses, enabling us to achieve both computational and live range optimality in our register promotion results. We discuss how to effect speculative code motion in the SSAPRE framework. We present two different algorithms for performing speculative code motion: the conservative speculation algorithm used in the absence of profile data, and the the profile-driven speculation algorithm used when profile data are available. We define the static single use (SSU) form and develop the dual of the SSAPRE algorithm, called SSUPRE, to perform the partial redundancy elimination of stores. We provide measurement data on the SPECint95 benchmark suite to demonstrate the effectiveness of our register promotion approach in removing loads and stores. We also study the relative performance of the different speculative code motion strategies when applied to scalar loads and stores.
Current Fluoroorganic Chemistry (2007)

The difficulty as well as the significance of the direct generation of metal enolates of The difficulty as well as the significance of the direct generation of metal enolates of α-CF3 ketones cannot be easily understood by chemists unfamiliar with fluorine. In sharp contrast to the great success in non-fluorine, hydrocarbon chemistry, fluorine chemistry has long been overshadowed. Metal enolates of carbonyl compounds are synthetically important in carbon-carbon bond forming reactions. However, the metal enolates of fluorinated carbonyl compounds have been severely limited to α-F metal enolates. α-CF3 Metal enolates have generally been recognized as unstable and difficult to prepare because of the facile β-M-F elimination. However, we have developed a direct generation and synthetic application of α-CF3 metal enolates. Therefore, the present results regarding the direct generation and synthetic use of metal enolates of α-CF3-ketones might be recognized as a paradigm shift to the general use of metal enolates in fluorine chemistry.
Active control of friction by transverse oscillations (2018)

The present paper is devoted to a theoretical analysis of sliding friction under the influence of in-plane oscillations perpendicular to the sliding direction. Contrary to previous studies of this mode of active control of friction, we consider the influence of the stiffness of the tribological contact in detail and show that the contact stiffness plays a central role for small oscillation amplitudes. In the present paper we consider the case of a displacement-controlled system, where the contact stiffness is small compared to the stiffness of the measuring system. It is shown that in this case the macroscopic coefficient of friction is a function of two dimensionless parameters—a dimensionless sliding velocity and dimensionless oscillation amplitude. In the limit of very large oscillation amplitudes, known solutions previously reported in the literature are reproduced. The region of small amplitudes is described for the first time in this paper.
Synthesis of the C1−C17 Segment of Phorboxazole B (2004)

The C1-C17 bis-oxane subunit 22 of phorboxazole B is efficiently synthesized by exploiting differential reactivities between similar substituents on the hydropyran rings in 4. Selective dihydroxylation of the equatorial vinyl group, hydroboration of the axial vinyl group, and intramolecular Mitsunobu lactonization serve to fully differentiate the similar hydropyrans.
Healthy and Pathological Brain Aging: From the Perspective of Oscillations, Functional Connectivity, and Signal Complexity (2017)

Healthy aging is associated with impairment in cognitive information processing. Several neuroimaging methods such as functional magnetic resonance imaging, positron emission tomography and near-infrared spectroscopy have been used to explore healthy and pathological aging by relying on hemodynamic or metabolic changes that occur in response to brain activity. Since electroencephalography (EEG) and magnetoencephalography (MEG) are able to measure neural activity directly with a high temporal resolution of milliseconds, these neurophysiological techniques are particularly important to investigate the dynamics of brain activity underlying neurocognitive aging. It is well known that age is a major risk factor for Alzheimer's disease (AD), and that synaptic dysfunction represents an early sign of this disease associated with hallmark neuropathological findings. However, the neurophysiological mechanisms underlying AD are not fully elucidated. This review addresses healthy and pathological brain aging from a neurophysiological perspective, focusing on oscillatory activity changes during the resting state, event-related potentials and stimulus-induced oscillatory responses during cognitive or motor tasks, functional connectivity between brain regions, and changes in signal complexity. We also highlight the accumulating evidence on age-related EEG/MEG changes and biological markers of brain neurodegeneration, including genetic factors, structural abnormalities on magnetic resonance images, and the biochemical changes associated with Aβ deposition and tau pathology.
Experimental study of single event upset and single event latch-up in SOI SRAM (2016)

Dielectric isolation of silicon on insulator (SOI) technology allows circuits to be designed that have reduced single event upset effects and are free from latch-up. For these reasons, SOI technologies are well suited for space applications. In this paper, we investigated both single event upset (SEU) and single event latch-up (SEL) effects of 512k bits SRAMs fabricated in SOI technology. The linear energy transfer (LET) of heavy ions used in the radiation experiment range from 32.4 to 99.8MeV-cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /mg. It is shown that devices fabricated in SOI technology which are radiation hardened through advanced and proprietary design, layout and process hardening techniques should exhibit high SEU levels(above 63.7MeV-cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /mg). Besides, the devices are SEL immune.
Chemoresistive Response of Nanoporous Activated Carbon Fibers Upon Hydrofluorocarbons Treatment (2019)

The thermal resistivity method, which is a convenient and sensitive to electrical resistance changes, was proposed for control of chemical modification of nanoporous activated carbon fibers (NACF) with hydrofluorocarbons (HFC). The surface state changes could be monitored by measuring Ohmic resistance during heating, physisorption, and chemical reaction between the activated carbon material and HFC. Thus, we found a correlation between the fluorine content in the resulted carbon material and electrical resistance, measured from the room temperature to 900 °C. It was shown that in this way the temperature of the beginning of a chemical reaction and the temperature of the most effective chemical modification could be determined. The thermal grafting of fluororganic groups onto NACF is assumed to be the reason for the changed electrical resistivity of the initial NACF.

SPRAY BREAKUP MECHANISM FROM THE HOLE-TYPE NOZZLE AND ITS APPLICATIONS (2000)

The fundamental physical processes of the spray breakup mechanism from the hole-type nozzle are examined. In early research it was believed that atomization of the liquid jet was caused by the interfacial forces existing between the issuing jet and the surrounding gas. However, investigation has determined that the strong turbulence in the nozzle hole due to cavitation phenomena contributes greatly to the disintegration of the liquid jet. To reveal the mutual relationships, experiments were performed under conditions with varying length-to-hole diameter ratios L/D, and different inlet shapes and different internal shapes of the nozzle. As a consequence of this study, it has been determined that the primary factor in atomization of the liquid jet is the disturbance of the liquid flow resulting from cavitation phenomena. Next, the effects of the internal flow in a diesel nozzle on the atomization of a spray were analyzed experimentally and numerically. Flow visualization studies were made using a transparent acrylic model nozzle.
Response time testing of temperature sensors using loop current step response method (2013)

The difference between the response time of temperature sensors in the lab and in actual operation can be significant. The technique for testing the response time of temperature sensors in the lab is known as the plunge test. The technique for testing temperature sensor response time in-situ is referred to as the Loop Current Step Response (LCSR) test. This paper presents the theoretical foundation of LCSR (the test theory, the LCSR equation, and the test procedures). It then details the author’s experimental research to validate its use in multiple applications (primarily in the nuclear power industry). The validity of the LCSR method depends on how well the design of the temperature sensor satisfies the assumptions of the LCSR test, the quality of the LCSR data in terms of signal-to-noise ratio, the application of proper sampling parameters for the data acquisition phase of LCSR, and the suitability of the algorithms and fitting processes used in the data analysis stage of LCSR. In multiple validation tests the author demonstrated that there is excellent (within ±10 percent) agreement between the median values of the response time produced by both the plunge and LCSR methods.
A new low-loss structure of abrupt bends in dielectric waveguides (1992)

In the proposed low-loss structure, a region whose refractive index is altered for reducing bending losses becomes much smaller. The beam propagation method is used to evaluate the loss of the modified corner bend proposed here. The validity of the results is confirmed in some cases through a comparison with those of a combination of the finite-element and boundary-element methods. Also, it is shown that the propagation characteristics of the proposed structure can be easily explained by using Snell's law.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
