Oral Antivirals for the Acute Treatment of Recurrent Herpes Labialis (2004)

Treatment with oral antivirals decreases the duration of lesion episodes and pain by approximately one day; however, the antivirals do not abort lesions from developing. Clinical implications of these results appear relatively modest.
SOM: Semantic obviousness metric for image quality assessment (2015)

Image quality assessment (IQA) tries to estimate human perception based image visual quality in an objective manner. Existing approaches target this problem with or without reference images. For no-reference image quality assessment, there is no given reference image or any knowledge of the distortion type of the image. Previous approaches measure the image quality from signal level rather than semantic analysis. They typically depend on various features to represent local characteristic of an image. In this paper we propose a new no-reference (NR) image quality assessment (IQA) framework based on semantic obviousness. We discover that semantic-level factors affect human perception of image quality. With such observation, we explore semantic obviousness as a metric to perceive objects of an image. We propose to extract two types of features, one to measure the semantic obviousness of the image and the other to discover local characteristic. Then the two kinds of features are combined for image quality estimation. The principles proposed in our approach can also be incorporated with many existing IQA algorithms to boost their performance. We evaluate our approach on the LIVE dataset. Our approach is demonstrated to be superior to the existing NR-IQA algorithms and comparable to the state-of-the-art full-reference IQA (FR-IQA) methods. Cross-dataset experiments show the generalization ability of our approach.
Capacitive Touch Communication: A Technique to Input Data through Devices' Touch Screen (2013)

As we are surrounded by an ever-larger variety of post-PC devices, the traditional methods for identifying and authenticating users have become cumbersome and time consuming. In this paper, we present a capacitive communication method through which a device can recognize who is interacting with it. This method exploits the capacitive touchscreens, which are now used in laptops, phones, and tablets, as a signal receiver. The signal that identifies the user can be generated by a small transmitter embedded into a ring, watch, or other artifact carried on the human body. We explore two example system designs with a low-power continuous transmitter that communicates through the skin and a signet ring that needs to be touched to the screen. Experiments with our prototype transmitter and tablet receiver show that capacitive communication through a touchscreen is possible, even without hardware or firmware modifications on a receiver. This latter approach imposes severe limits on the data rate, but the rate is sufficient for differentiating users in multiplayer tablet games or parental control applications. Controlled experiments with a signal generator also indicate that future designs may be able to achieve data rates that are useful for providing less obtrusive authentication with similar assurance as PIN codes or swipe patterns commonly used on smartphones today.
Modular Pulse Synthesizer for Transcranial Magnetic Stimulation with Flexible User-Defined Pulse Shaping and Rapidly Changing Pulses in Sequences (2022)

The temporal shape of a pulse in transcranial magnetic stimulation (TMS) influences which neuron populations are activated preferentially as well as the strength and even direction of neuromodulation effects. Furthermore, various pulse shapes differ in their efficiency, coil heating, sensory perception, and clicking sound. However, the available TMS pulse shape repertoire is still very limited to a few pulses with sinusoidal or near-rectangular shapes. Monophasic pulses, though found to be more selective and stronger in neuromodulation, are generated inefficiently and therefore only available in simple low-frequency repetitive protocols. Despite a strong interest to exploit the temporal effects of TMS pulse shapes and pulse sequences, waveform control is relatively inflexible and only possible parametrically within certain limits. Previously proposed approaches for flexible pulse shape control, such as through power electronic inverters, have significant limitations: Existing semiconductor switches can fail under the immense electrical stress associated with free pulse shaping, and most conventional power inverter topologies are incapable of generating smooth electric fields or existing pulse shapes. Leveraging intensive preliminary work on modular power electronics, we present a modular pulse synthesizer (MPS) technology that can, for the first time, flexibly generate high-power TMS pulses with user-defined electric field shape as well as rapid sequences of pulses with high output quality. The circuit topology breaks the problem of simultaneous high power and switching speed into smaller, manageable portions. MPS TMS can synthesize practically any pulse shape, including conventional ones, with fine quantization of the induced electric field.

Implementation of checkout/checkin mechanism on object-oriented database systems (2002)

The authors discuss the implementation of the checkout/checkin mechanism in object-oriented database systems. Objects are no longer modified directly in the public database. Each user has a private workspace and his/her tasks are performed in the workspace. When the tasks are done, the user checks in modified objects in the public database. They introduce several classes of long duration locks in order to allow users to lock objects for a long time. A composite object, version, versionable object, or simple object may be the granularity of a checkout operation. They effectively maintain the version derivation graphs in a public database and workspaces and manage checkouts of composite objects.

Tennyson and after. (2008)

This thesis is a study of the posthumous literary reception and reputation of Alfred Tennyson, from the year of his death, 1892, to 1950. Its focus is on allusions to Tennyson's work in poetry, fiction and drama, but it also takes works of criticism and journalism into account, as well as other evidence of Tennyson's continuing readership in the period. The thesis approaches the period by decades, involving in-depth assessments of Tennyson's influence on the work of writers as diverse as Conrad, Housman, Austin, Forster, Bennett, Owen, Sassoon, Lawrence, T. S. Eliot, Joyce, Woolf, Pound, Auden, Evelyn Waugh, and Graham Greene. Their various responses - from the appreciative to the scornful, the ambivalent to the oedipal - are put into context using works of criticism which discuss Tennyson, by both canonical writers such as A. C. Bradley and F. R. Leavis as well as less famous critics. The thesis calls into question Bradley's idea of a 'reaction against Tennyson' having already reached its peak by 1917. I will show that, in reality, Tennyson's influence and popularity endured long into the twentieth century, and that the aftermath of the Great War meant that the poet's work was truly at its nadir of popularity in the late 1920s and 1930s. The thesis will also address Tennyson's ultimate resurgence in popularity in the 1940s, partly as a result of the impact of World War II but partly as the writers who had seemed radical earlier in the century (not least T. S. Eliot) felt more comfortable about accepting their influences. The thesis ends by placing this in the context of the wider revival of interest in Victorian literature and culture in the 1940s and early 1950s The appendix of the thesis is a database of Tennyson's poems which appeared in anthologies in the period.
High-power single-mode AlGaAs lasers with bent-waveguide nonabsorbing etched mirrors (1992)

A nonabsorbing etched mirror structure for AlGaAs single-quantum-well graded-refractive-index separate-confinement heterostructure ridge lasers is analyzed with respect to mirror coupling coefficient, threshold current penalty, and far-field pattern. Measurements of the mirror temperature showed a reduction from 50 to 20 K at 30 mW optical power depending on the degree of overlap of the optical intensity with the absorbing bent-waveguide profile. Pulsed catastrophic optical damage power levels up to 400 mW and a thermally saturated cw power of 165 mW with single-mode operation up to 80 mW have been achieved. Lifetime measurements at 40 mW constant optical power indicated degradation rates ≤10−5/h comparable to AlGaAs lasers with cleaved and coated mirrors.
Studies on Antitumor Substances. VII. Reaction of N-Amidino-O-alkylisourea with Some Carboxylic Esters (1968)

The reaction of N-amidino-O-alkylisourea with some carboxylic esters was attempted. Condensation with diethyl oxalate in alcohol gave alkyl 4-amino-6-alkoxy-s-triazine-2-carboxylate through the formation of the five membered-ring intermediate. Alkyl 4-amino-6-alkoxy-s-triazine-2-carboxylate was easily converted into the coresponding amide with a variety of amines. Condensation with ethyl acetoacetate gave 6-methyl-2-alkoxyamidino-4-pyrimidinol and 4-amino-2-alkoxy-6-acetomethyl-s-triazine. Condensation with ethyl cyanoacetate afforded only 4-amino-2-alkoxy-6-cyanomethyl-s-triazine, but not any expected pyrimidinol. Condensation with ethyl chloroacetate gave 4-amino-2-alkoxy-6-chloromethyl-s-triazine, which was converted into 4-amino-2-alkoxy-6-substituted amino-s-triazine with a variety of amines.
Detection of norepinephrine in whole blood via fast scan cyclic voltammetry (2017)

Bioelectronic Medicines is an emerging field that capitalizes on minimally-invasive technology to stimulate the autonomic nervous system in order to evoke therapeutic biomolecular changes at the end-organ. The goal of Bioelectronic Medicines is to realize both 'precision and personalized' medicine. 'Precise' stimulation of neural circuitry creates biomolecular changes targeted exactly where needed to maximize therapeutic effects while minimizing off-target changes associated with side-effects. The therapy is then 'personalized' by utilizing implanted sensors to measure the biomolecular concentrations at, or near, the end-organ of interest and continually adjusting therapy to account for patient-specific biological changes throughout the day. To realize the promise of Bioelectronic Medicines, there is a need for minimally invasive, real-time measurement of biomarkers associated with the effects of autonomic nerve stimulation to be used for continuous titration of therapy. In this study we examine the feasibility of using fast scan cyclic voltammetry (FSCV) to measure norepinephrine levels, a neurochemical relevant to end-organ function, directly from blood. FSCV is a well-understood method for measuring electroactive neurochemicals in the central nervous system with high temporal and high spatial resolution that has yet to be adapted to the study of the autonomic nervous system. The results demonstrate that while detecting the electroactive neurochemical norepinephrine in blood is more challenging than obtaining the same FSCV measurements in a buffer solution due to biofouling of the electrode, it is feasible to utilize a minimally invasive FSCV electrode to obtain neurochemical measurements in blood.
<i>S</i> parameter measurements on single superconducting thin-film three-terminal devices made of high-<i>T</i> <i>c</i> and low-<i>T</i> <i>c</i> materials (1989)

We have investigated three-terminal single-layer thin-film superconducting devices made of YBaCuO and Nb. The devices incorporate regions of weak superconductivity in multiple parallel links that are influenced by current in a separate control line. These experiments were designed to study the possible application of this device as an rf amplifier. With the device biased, rf power was applied to the control line and the transmission coefficient, S21, was measured. The reverse transmission coefficient, S12, was also measured for comparison. Upon biasing into a flux flow state, the S21 of the device at rf frequencies was found to increase 10–15 dB over the zero bias value and over the reverse feed (S12 ) value. The device behaved linearly up to power inputs of +5 dBm (1-dB compression point). The bandwidth was limited only by the impedance transformer.
Different methods for reducing detent force in a permanent magnet linear synchronous motor (2010)

In almost every permanent magnet (PM) excited machine, detent forces arise, which are caused by the permanent magnets in connection with the iron core. In case of permanent magnet linear synchronous motors (PMLSM), two sources of detent forces have to be taken into account: Cogging forces based on the stator slots and detent forces caused by the end effects. Both forces have a negative influence on the operating behavior of PM motors. Therefore it is necessary and important to consider these effects during the motor design.
The Hearing-Dependent Daily Activities Scale to Evaluate Impact of Hearing Loss in Older People (2008)

The HDDA scale constitutes a clinically useful instrument for identifying the impact of hearing loss on daily life in the elderly, a condition frequently overlooked during routine medical check-ups. This tool has acceptable psychometric properties and high internal consistency.
Organometallic polymers, 28 Condensation polymerization of cobalticinium salts (1974)

Abstract Ionic polyesters of fairly low molecular weights were prepared by melt phase polytransesterification of 1,1′‐bis(carbethoxy)cobalticinium hexafluorophosphate ( 1a ) and diols such as 1,10‐decanediol and 1,4‐bis(hydroxymethyl)benzene. Attempts to prepare polyamides by melt condensation from alkylene diammonium salts of 1,1′‐bis(carboxy)cobalticinium hexafluorophosphate 5a–d resulted in extensive decomposition, and pure polyamides could not be obtained. The polyesters were characterized by analyses, IR spectroscopy, gel permeation chromatography, and differential scanning calorimetry.
Bit-depth scalable video coding with new inter-layer prediction (2011)

The rapid advances in the capture and display of high-dynamic range (HDR) image/video content make it imperative to develop efficient compression techniques to deal with the huge amounts of HDR data. Since HDR device is not yet popular for the moment, the compatibility problems should be considered when rendering HDR content on conventional display devices. To this end, in this study, we propose three H.264/AVC-based bit-depth scalable video-coding schemes, called the LH scheme (low bit-depth to high bit-depth), the HL scheme (high bit-depth to low bit-depth), and the combined LH-HL scheme, respectively. The schemes efficiently exploit the high correlation between the high and the low bit-depth layers on the macroblock (MB) level. Experimental results demonstrate that the HL scheme outperforms the other two schemes in some scenarios. Moreover, it achieves up to 7 dB improvement over the simulcast approach when the high and low bit-depth representations are 12 bits and 8 bits, respectively.
Wafer level packaging of micro-machined gas sensors (2006)

We present a novel approach to combine wafer level packaging (WLP) with micro-machined hotplate gas-sensing elements (Patent Application WO03067241 2003-08-14). This concept allows liquid tight sealing of gas sensor devices, protecting them during production (e.g. wafer dicing) and later in the application, while still allowing the target gases to reach the sensing layer. The basis of the WLP is the combination of a structured Pyrex wafer with a micro-machined substrate wafer. Thereafter, thick film SnO/sub 2/ layers are deposited and stabilized before a diffusion membrane is attached, sealing the wafer stack.
Payment Card Industry Data Security Standard Compliance in Restaurants (2008)

ABSTRACT In order to improve the security of customer data, the credit card companies have come together to create a security standard called the Payment Card Industry Data Security Standard (PCI DSS), which involves mandatory requirements for merchants that accept credit card transactions. All restaurants that accept a credit card must comply with PCI DSS. The purpose of the study was to examine the PCI DSS compliance levels of quick-service, casual/family, and fine dining restaurants. A random sample of one thousand restaurant managers who are in charge of information technology at their companies and were subscribers of Hospitality Technology magazine were surveyed. One hundred ninety managers responded to the survey. The results indicate that restaurants are far from full compliance with PCI DSS. This may have significant financial and non-financial consequences for restaurant owners and operators.
Characterization of Nanostructured Titanates Obtained by Alkali Treatment of TiO<sub>2</sub>-Anatases with Distinct Crystal Sizes (2007)

Layered titanate nanotubes (TTNT) with a general formula NaxH2-xTi3O7·nH2O were synthesized by hydrothermally reacting TiO2-anatase with NaOH at 120 °C. Detailed TGA and XRD characterization indicated that the as-synthesized material rich in sodium as an interlayer cation contained intercalated water (n), which was reduced substantially after nearly complete proton exchange (x = ∼0), while the interlayer distance decreased approaching the interlayer distance d200 of H2Ti3O7. Chemical composition and crystal structure of TTNT as well as their dependence on sodium content were not affected by the crystallite size of the starting anatase. On the other hand, TEM examination and N2 adsorption measurements revealed distinct morphology at the nanometer scale and different textural properties depending on the precursor TiO2. Such dependence was rationalized based on a dissolution−recrystallization mechanism.
A facile synthesis of 5,7‐dihydro‐5‐oxopyrido[3′,2′:5,6]pyrimido[1,2‐<i>a</i>]benzimidazoles. A new heterocyclic ring system (1986)

Abstract Reaction between 2‐chloropyridine‐3‐carbonyl chloride and 1‐alkyl‐2‐aminobenzimidazoles afforded the N ‐(1‐alkylbenzimidazole‐2‐yl)‐2‐chloropyridine‐3‐carboxamides, which were cyclized to 5,7‐dihydro‐5‐oxopyrido[3′,2′:5,6]pyrimido[1,2‐ a ]benzimidazoles. The assigned structures of these hitherto unknown heterocyclic compounds were confirmed by their ir and 1 H nmr spectra and chemical evidence.
Importance of bone marrow cell dose in bone marrow transplantation (1992)

The importance of the size of the infused marrow cell dose (MCD) was investigated in 274 patients undergoing allogeneic BMT between 1975 and 1990. Among those, 65 had acute myelogenous leukemia (AML), 79 acute lymphoblastic leukemia (ALL), 58 chronic myelogenous leukemia (CML) and 25 severe aplastic anemia (SAA). MCD was analyzed in bivariate and multivariate analysis together with 6 other clinical factors. In multivariate analysis a low MCD was significantly associated with increased incidence of acute graft-versus-host disease (GvHD) in all patients (p = 0.005) and in ALL patients (p = 0.02) whereas in CML a high dose was instead correlated to acute GvHD. A low MCD was also correlated to an increased incidence of symptomatic cytomegalovirus (CMV) infection (p = 0.001). A low MCD was also correlated to death in acute GvHD in all patients (p = 0.01) and to a poor survival in all patients (p = 0.04) (AML, p = 0.07).
Transcriptional control of human papillomavirus (HPV) oncogene expression: composition of the HPV type 18 upstream regulatory region (1993)

The malignant transformation potential of high-risk human papillomaviruses (HPVs) is closely linked to the expression of the viral E6 and E7 genes. To elucidate the molecular mechanisms resulting in HPV oncogene expression, a systematic analysis of the cis-regulatory elements within the HPV type 18 (HPV18) upstream regulatory region (URR) which regulate the activity of the E6/E7 promoter was performed. As the functional behavior of a given cis-regulatory element can be strongly influenced by the overall composition of a transcriptional control region, individual elements were inactivated by site-directed mutagenesis in the physiological context of the complete HPV18 URR. Subsequently, the effects of these mutations on the activity of the E6/E7 promoter were assessed by transient transfection assays. We found that the transcriptional stimulation of the E6/E7 promoter largely depends on the integrity of cis-regulatory elements bound by AP1, SP1, and in certain epithelial cells, KRF-1. In contrast to previous reports by implying a key role for NF1 and Oct-1 recognition motifs in the stimulation of papillomavirus oncogene expression, the inactivation of these elements in the context of the HPV18 URR did not strongly affect the transcriptional activity of the E6/E7 promoter. Mutation of a promoter-proximal glucocorticoid response element completely abolished dexamethasone inducibility of the HPV18 E6/E7 promoter and resulted in an increase of its basal activity. Functional dissection of the HPV18 constitutive enhancer region indicates that its transcriptional activity is largely generated by functional synergism between a centrally located AP1 module and thus far undetected cis-active elements present in the 5' flank of the enhancer. Furthermore, comparative analyses using homologous and heterologous promoters show that the transcriptional activity of HPV18 enhancer elements is influenced by the nature of the test promoter in a cell-type-specific manner.
