Improving convergence in scattering problems by smoothing discrete constraints using an approximate convolution with a smoothed composite Green’s function (1998)

A method for efficiently treating discrete structural constraints using an approximate Green’s function approach to smooth the constraint influence is presented. A method called analytical/numerical matching is used to formulate a composite Green’s function that captures the local high-resolution content associated with the discrete force in a separate analytic local solution. This local solution in turn implies a smooth replacement for the original discrete force. This replacement is approximately integrated following the Green’s function formalism modified by a Taylor expansion of the forcing strength function. A smooth replacement for the discrete constraint results. This new smoothed problem converges more rapidly than the original discrete one. However, the difference between the smooth solution and the original is retained in the analytic local solution. The result is a composite solution of the original system that is more accurate for a given computational resolution compared with treating the discrete constraint influence directly. In the present example, a modal method is used. Therefore, a given computational resolution is measured by number of modes calculated. The method is demonstrated in the case of beam incident scattering from an infinite thin elastic shell periodically constrained by rings. [Work supported by ONR.]
Complexation-Induced N‒P Axial Chirality in Sm(II) N-Phosphine-Oxide-Substituted Imidazolylidene and Imidazolinylidene Complexes (2022)

Two types of Sm(II) complexes bearing either an N-phosphine-oxide-substituted imidazolylidene (PoxIm) or the corresponding imidazolinylidene (SPoxIm) were successfully prepared and characterized using single crystal X-ray diffraction analysis. The general formula of the structures of the complexes was found to be (anti-k-O-(S)PoxIm)nSmX2(THF)m where X = I, n = 2, m = 2 or X = pentamethylcyclopentadienyl, n = 1, m = 0. The carbene carbon atoms remained intact in these complexes. In some cases, axial chirality was clearly induced around the N‒P bonds due to the restricted rotation of the N-phosphinoyl moieties, which arises from the formation of N-phosphinoyl oxygen‒Sm(II) bonds. This work highlights a rare example of complexation-induced N‒P axial chirality and new aspects regarding lanthanide complexes of multifunctional multipurpose carbenes.
Definition of a "trigger" stage in the NK cytolytic reaction sequence by a monoclonal antibody to the glycoprotein T-200. (1983)

The monoclonal antibody 13.1 recognizes an epitope on the T-200 glycoprotein and blocks natural killer (NK) lysis of the erythroleukemia target K562, but not of the acute lymphoblastic leukemia T cell target Molt-4. The inhibitory effect is at the killer cell level and not the target cell level, which suggests that 13.1 may react with a receptor on NK cells. This hypothesis was tested in assays to delineate precisely where in the NK cytolytic reaction sequence 13.1 interferes with lysis; 13.1 did not block initial NK-target cell interaction as measured in a target binding cell assay. With the use of a Ca++ pulse technique, 13.1 did not block any events occurring during Ca++-dependent programming. If the antibody was added after conjugate formation but before the addition of CaCl2 to initiate programming, however, full inhibition of NK lysis occurred. Therefore, 13.1 antibody defines a distinct stage in the NK reaction sequence that links target binding to the initiation of calcium-dependent programming events. NK cell binding alone is not sufficient to trigger lytic events, and the presence of a second structure or a distinct portion on a single structure is required to trigger lysis. We show that 13.1 blocks the ability of K562 to inhibit NK killing of Molt-4 in a cold target inhibition assay. Therefore, despite the fact that 13.1 does not disrupt conjugate formation, NK specificity may exist at a post-binding site rather than at the initial NK-target binding interaction. Our data suggest that the T-200 glycoprotein on NK cells triggers the initiation of the lytic events.

Joint User Selection and Beamforming Schemes for Inter-Operator Spectrum Sharing (2013)

These results indicated that systemic lupus erythematosus was not characterized by a modulation of the growth hormone/insulin-like growth factor-1 paracrine axis when serum samples from systemic lupus erythematosus patients were compared to age- matched normal female subjects. These results in systemic lupus erythematosus differ from those previously reported in other musculoskeletal disorders such as rheumatoid arthritis, osteoarthritis, fibromyalgia, diffuse idiopathic skeletal hyperostosis and hypermobility syndrome where significantly higher serum growth hormone levels were found. Somatostatin levels in elderly systemic lupus erythematosus patients may provide a clinical marker of disease activity in these patients.
Temperature dependence of carrier transport in conducting polymers: Similarity to amorphous inorganic semiconductors (2002)

We improve the trapping model of carrier transport in conducting polymers by integrating the coupled Poisson and continuity equations numerically. In the case of exponentially distributed traps calculated log J vs 1/T plots are straight lines indicating that the activation of carriers to the extended states can be described by one single activation energy, Eeff. The improved trapping model agrees well with the recent experimental data at high temperatures (i.e., near room temperature). At low temperatures the trapping model does not work since the available thermal energy is not sufficient to ionize the traps. We use the hopping mobility model at low temperatures. The model explains the low-temperature J–V characteristics well. This mechanism of charge carrier transport is similar to that used for interpreting experiments on inorganic amorphous materials.
Organic Light Emitting Diode with Uniform Luminance Distribution and Enhanced Efficiency via Random Embossing Structure (2014)

Using the lateral phases separation of a binary immiscible polymer blend, we have fabricated a random embossing structure (RES). The RES was investigated as a potential structure for organic light-emitting diode (OLED) light extraction. Our RES yields uniform light extraction in a broad angle (0°∼70°) range with spectral stability. Blue phosphorescence OLEDs equipped with the RES showed an enhancement of 20% in external quantum efficiency (EQE)and spectral stability within Δx,y < 0.01 in a viewing angle range of 0°∼70°. Our RES provides a new and practical approach for achieving enhanced efficiency and spectral stability of OLEDs.
An Isolated Multilevel Quasi-Resonant Multiphase Single-Stage Topology for 380-V VRM Applications (2019)

In order to increase the efficiency of modern microprocessor power supplies used in data centers, 380-V dc power distribution systems have been attracting attention due to their high efficiency and high reliability. This paper presents an innovative single-stage approach for 380-V voltage regulator modules (VRMs) based on a quasi-resonant multilevel topology constant on-time operation. The proposed topology inherently integrates the multiphase approach, providing fast phase shedding and flat high-efficiency curves even at light-load conditions. This is a unique advantage, which is not possible to establish in the two-stage approach, which is very important in server architectures, and where high efficiency is required even at light-load conditions. This paper analyzes the circuit topology and proposes a control architecture for fast transient response, including current-sharing capabilities. The digital controller has been implemented in 0.16-μ m lithography together with a digital pulsewidth modulation with a 195-ps resolution and a 40-MS/s 7-bit analog-to-digital converter. Experimental results show an efficiency of 93% for a 120-A 380-1.8-V VRM power supply.

Effect of Periocular Humidity on the Tear Film Lipid Layer (1996)

The purpose of this study was to determine the relationship between the tear film and humidity by examining whether alterations in periocular humidity influence the thickness of the tear film lipid layer. Thirteen dry eye subjects presenting with a baseline lipid layer thickness of < or = 60 nm were fitted with modified swim goggles in which the right eye (OD) was exposed to conditions of high humidity and the left eye (OS) remained exposed to ambient room conditions. The lipid layer was monitored over a 60-min time course with goggles on and for an additional 60 min following goggle removal. The OD lipid layer increased significantly in thickness within 5 min of exposure to conditions of high humidity (p < 0.0001), reaching a maximum increase of 66.4 nm after 15 min of goggle wear (p < 0.0001). This maximum increase to a lipid layer thickness of 120.5 nm was maintained at the 30- and 60-min goggle time points. No significant change was detected OS. Following goggle removal, OD values declined but remained significantly elevated over the OS lipid layer thickness throughout the 60-min postgoggle period. Moderate to total relief of dry eye symptoms was reported during goggle wear and generally persisted at a reduced level for 1-3 h following goggle removal. Increased periocular humidity results in an increase in tear film lipid layer thickness, possibly by providing an environment that is more conducive to the spreading of meibomian lipid and its incorporation into the tear film.
Patient satisfaction with the dental services offered by a dental Hospital in India (2014)

Introduction: A major component of quality of health care is patient satisfaction. Patient satisfaction is multifaceted and a very challenging outcome to define. Patient expectations of care and attitudes greatly contribute to the satisfaction; other psychosocial factors, including facilities and treatments services are also known to contribute to patient satisfaction scores. Aim: To measure patient satisfaction about facilities, services and treatments offered by a dental hospital in India. Materials and Methods: Self administrated questionnaire was distributed to outpatients reporting to the dental hospital for treatment. The questionnaire consisted of 30 items that included information about personal data of the patients and their satisfaction with the facilities, services and treatment received in the hospital. Results: About 89.9% of patients felt that the cost of dental hygiene services were reasonable, 57.6% of patients felt that drinking water facilities were enough in the hospital, 31.9% of patients felt that they have problem with scheduling appointments, 86% of patients felt that they had problem in contacting student dentist. Conclusion: The majority of the patients were satisfied with the facilities, services and treatment received at hospital except for facilities such as water supply and scheduling appointments with patient convenience.
Three-Phase Split-Source Inverter-Fed PV Systems: Analysis and Mitigation of Common-Mode Voltage (2020)

Common-mode voltage (CMV), caused by standard high-frequency pulsewidth modulated (PWM) voltage source inverters (VSIs), is a major area of interest in various applications, such as electric motor drives, transformerless photovoltaic systems, and grid-tied inverters. Since VSIs have only the buck capability during the inversion mode, an additional boosting stage either in the dc side or in the ac side has to be utilized for low-voltage-fed applications. On the other hand, single-stage solutions, with buck and boost capabilities, represent an interesting alternative with reduced cost, complexity, and converter volume. Among the possible single-stage solutions, split-source inverter (SSI), which has been recently proposed, has several merits over its counterparts. One of the questionable aspects concerning this topology is the CMV, which has not been investigated yet. This article examines the induced CMV with the SSI. This is done by examining the CMV waveforms for VSI and SSI topologies, and then, comparing each other under different PWM schemes. Furthermore, this article proposes the use of the discontinuous space vector PWM scheme with the SSI to mitigate the CMV, where the analysis shows a significant reduction in the CMV compared to the other schemes. In order to validate the introduced analysis, simulation model has been designed using MATLAB/Simulink environment, and simulation results are presented. Moreover, a prototype has been built-up for testing the proposed concepts and the obtained experimental results are provided.
Identification of New SRF Binding Sites in Genes Modulated by SRF Over-Expression in Mouse Hearts (2011)

SRF-modulated genes are actively regulated under various physiological and pathological conditions. We have discovered that a large number of cardiac genes have classic SRF binding sites and were significantly modulated in the Mild-O-SRF Tg mouse hearts. Hence, the mild elevation of SRF protein in the heart that is observed during typical adult aging may have a major impact on many SRF-modulated genes, thereby affecting cardiac structure and performance. The results from our study could help to enhance our understanding of SRF regulation of cellular processes in the aged heart.

Electron Trapping in HfAlO High-$\kappa$ Stack for Flash Memory Applications: An Origin of $V_{\rm th}$ Window Closure During Cycling Operations (2011)

Endurance is one of the key criteria for Flash memory technologies, particularly for the generations beyond 30 nm with high-κ materials. It is observed in this paper that the electron trapping in high-κ layers causes threshold-voltage window closure under dynamic program/erase cycling operations. This closure does not originate from the generation of new traps or from further trapping of electrons injected from the gate during erasing. By utilizing a recently developed multipulse technique, it is found that the energy distribution of the electron trapping in the high-κ layer significantly changes after cycling. Electron trapping at the deeper energy levels continuously increases as cycling proceeds, because it does not reach saturation within one programming pulse. The trapping in deep levels cannot be discharged under typical erase conditions, and an increase in deep-level trapping also causes a reduction of trapping at shallow levels. It is concluded that the window closure observed in this paper is caused by a combination of increased deep trapping after erasing and a reduction of shallow trapping after programming.

Adjuvant postoperative radiotherapy, chemotherapy, and immunotherapy in stage III breast cancer (1984)

One hundred twenty pathologically confirmed operable Stage III (T3N0-2) breast cancer patients were randomized to receive either postoperative radiotherapy or chemotherapy, or a combination of these, with or without levamisole immunotherapy. Radiotherapy was given to regional lymph node areas and chest wall. Chemotherapy consisted of 6 cycles of Adriamycin (doxorubicin) (45 mg/m2), vincristine (1.2 mg/m2) intravenously, and cyclophosphamide (200 mg/m2 for 5 days) perorally every 4 weeks. Peroral levamisole, 150 mg a day, 2 days weekly, was given as an immunotherapy. The 3-year results are described in this article. The effect of levamisole on the prognosis cannot be evaluated yet because of the short follow-up period. The disease-free survival was almost equal in each patient group, however, some benefit was achieved by levamisole (a shift of disease-free survival from 12 to 18 months). The patients receiving radiotherapy alone had the poorest prognosis: 68% had a recurrent tumor, and 57% were alive. In the chemotherapy group, the figures were 53% and 72%, respectively. Patients who received a combined treatment had the best prognosis: 13% had a recurrent tumor, and 90% survived 3 years. There was a statistically significant difference in the recurrence rate between any single therapy and the combined treatment (radiotherapy to combined treatment, P less than 0.001, chemotherapy to combined treatment, P less than or equal to 0.01 chi-square test). In overall survival, a statistically significant difference was reached between radiotherapy and combination treatment groups (P less than 0.01, chi-square test). Radiotherapy gave a good local control of the tumor, and chemotherapy decreased the number of metastases. The nonmetastatic axillary lymph node status and secondary amenorrhea or severe menstrual disturbances were of positive prognostic value. The side effects due to radiotherapy and chemotherapy were moderate and tolerable. The dose of Adriamycin had to be reduced only in four patients. All of the patients receiving chemotherapy had a transient total alopecia. Three of them had nonlethal arrhythmias, and one had skin rash. Levamisole was found very toxic with 9 cases of transient agranulocytosis, leading to the discontinuation of immunotherapy in 22 of 59 patients. Our results show that radiotherapy controls the tumor only locally and chemotherapy systematically, but the best patient-saving results are achieved with a combination of radiotherapy and chemotherapy. The disease-free and overall survival are statistically significant, and favor the combined therapy.

QCM-D Study of Time-Resolved Cell Adhesion and Detachment: Effect of Surface Free Energy on Eukaryotes and Prokaryotes (2020)

Cell-material interactions are crucial for many biomedical applications, including medical implants, tissue engineering, and biosensors. For implants, while the adhesion of eukaryotic host cells is desirable, bacterial adhesion often leads to infections. Surface free energy (SFE) is an important parameter that controls short- and long-term eukaryotic and prokaryotic cell adhesion. Understanding its effect at a fundamental level is essential for designing materials that minimize bacterial adhesion. Most cell adhesion studies for implants have focused on correlating surface wettability with mammalian cell adhesion and are restricted to short-term time scales. In this work, we used quartz crystal microbalance with dissipation monitoring (QCM-D) and electrical impedance analysis to characterize the adhesion and detachment of <i>S. cerevisiae</i> and <i>E. coli</i>, serving as model eukaryotic and prokaryotic cells within extended time scales. Measurements were performed on surfaces displaying different surface energies (Au, SiO<sub>2</sub>, and silanized SiO<sub>2</sub>). Our results demonstrate that tuning the surface free energy of materials is a useful strategy for selectively promoting eukaryotic cell adhesion and preventing bacterial adhesion. Specifically, we show that under flow and steady-state conditions and within time scales up to ∼10 h, a high SFE, especially its polar component, enhances <i>S. cerevisiae</i> adhesion and hinders <i>E. coli</i> adhesion. In the long term, however, both cells tend to detach, but less detachment occurs on surfaces with a high dispersive SFE contribution. The conclusions on <i>S. cerevisiae</i> are also valid for a second eukaryotic cell type, being the human embryonic kidney (HEK) cells on which we performed the same analysis for comparison. Furthermore, each cell adhesion phase is associated with unique cytoskeletal viscoelastic states, which are cell-type-specific and surface free energy-dependent and provide insights into the underlying adhesion mechanisms.

Automatic identification of local geometric properties during teleoperation (2002)

During teleoperation, a human operator often receives only 2D visual feedback from the remote environment. While a variety of kinematic sensors exist on the remote manipulator for control purposes, the information inherent in these signals is rarely extracted and presented to the operator in a useful form. This paper investigates the extraction of such information through the development of an algorithm that estimates the geometric properties of a manipulated object and its environment using the remote robot sensors and knowledge of the task being performed. The focus of the paper is the development of contact constraint equations parametrized by the desired geometric properties and the automatic segmentation of the data stream according to the set of active contacts. The approach is validated for 3D peg-in-hole insertion using a desktop teleoperator system.

ML detection and decoding of space-time codes (2001)

Space-time coding (STC) schemes for communication systems employing multiple transmit and receive antennas have recently been attracting increased attention. We address the optimal detection of space-time codes under various interference conditions and the optimal information transfer from the detector to an error-correcting channel decoder. We discuss various aspects of channel modelling for STC communication receivers. In particular, while many previous works on the topic commonly use a stochastic channel model, we provide some justification for modelling the channel as a deterministic unknown when designing receiver algorithms.
