FlashLinQ: enabling a mobile proximal internet (2013)

FlashLinQ is a wireless communications system founded on the realization of a "wireless sense"-a sense whose embodiment in devices provides Internet application peers with a direct awareness of each other's physical proximity and relevance, creating a new form of proximityaware internetworking, and thereby realizing a necessary step towards what we term a "Mobile Proximal Internet". The need for such a system arises from the pervasive spread of Internet devices and applications in our daily lives, and the practical limitations of current communications technologies in conveying knowledge of mutual proximity and relevance. In this paper, we introduce a mobile proximity-aware social network use case, and describe the overview of technology and our simulation, prototype implementation and initial field/lab test results.
Stability Analysis of Bidirectional Dual Active Bridge Converter With Input and Output LC Filters Applying Power-Feedback Control (2022)

This article analyzes the dynamic characteristics of a dual active bridge (DAB) converter with input/output LC filters connected and power-feedback control applied, and then discusses an impedance stability criterion about both side LC filters and the converter. Power control is suitable as a control method for grid-connected converters because of its affinity with the energy management system, which is being introduced as a new way to operate power systems in recent years. In order to provide stable power supply, it is necessary to ensure the stability of the converter, and information on dynamic characteristics is essential for the design and development of converters. Since there are no previous papers found yet where the impedance stability criterion is applied when LC filters are connected to both ends of a bidirectional DAB converter, this article discusses the procedures and key points to be considered to apply the criterion. Based on the analysis, the design guidelines of the system will be discussed.
Velocardiofacial Syndrome (2009)

Velocardiofacial syndrome (VCFS) also known as DiGeorge, conotruncal anomaly face and Cayler syndromes is caused by a microdeletion in the long arm of chromosome 22. We review the history of the syndrome from the first clinical reports almost half a century ago to the current intriguing molecular findings associating genes from the microdeletion region and the physical and neuropsychiatric phenotype of the syndrome. Velocardiofacial syndrome has a wide spectrum of more than 200 physical manifestations including palate and cardiac anomalies. Yet, the most challenging manifestations of VCFS are the learning disabilities and neuropsychiatric disorders. As VCFS is relatively common and as up to one third of the subjects with VCFS develop schizophrenia like psychotic disorder the syndrome is the most commonly known genetic risk factor to schizophrenia. Identifying the genetic, cognitive and psychiatric risk factors for VCFS-schizophrenia is under the focus of intensive research.
The transition from Elasto‐Hydrodynamic to Mixed Regimes in Lubricated Friction of Soft Solid Surfaces (2023)

Lubricated contacts in soft materials are common in various engineering and natural settings, such as tires, haptic applications, contact lenses, and the fabrication of soft electronic devices. Two major regimes are elasto-hydrodynamic lubrication (EHL), in which solid surfaces are fully separated by a fluid film, and mixed lubrication (ML), in which there is partial solid-to-solid contact. The transition between these regimes governs the minimum sliding friction achievable and is thus very important. Generally, the transition from EHL to ML regimes is believed to occur when the thickness of the lubricant layer is comparable with the amplitude of surface roughness. Here, it is reported that in lubricated sliding experiments on smooth, soft, poly(dimethylsiloxane) substrates, the transition can occur when the thickness of the liquid layer is much larger than the height of the asperities. Direct visualization of the "contact" region shows that the transition corresponds to the formation of wave-like surface wrinkles at the leading contact edge and associated instabilities at the trailing contact edge, which are believed to trigger the transition to the mixed regime. These results change the understanding of what governs the important EHL-ML transition in the lubricated sliding of soft solids.
Impact of Use Conditions on Dielectric and Conductor Material Models for High-Speed Package Interconnects (2019)

Use conditions based on temperature and humidity can have a significant impact on the package material properties and loss, which is required to be included in modeling assumptions to be able to set realistic specifications. The dielectric loss is affected by both temperature and humidity through material properties. The conductor loss, however, is affected by only temperature explicitly through conductivity and implicitly through skin depth and surface roughness modeling. This paper presents a systematic use condition-dependent methodology for package high-speed interconnects including a robust dielectric material characterization metrology. Correlation to high fidelity insertion loss measurements at different temperatures indicates that the roughness correction factor extracted at one temperature does not fit all and leads to underestimating the loss at higher temperatures. Without loss of generality due to a unified form of correction factors of the existing common roughness models, a modified version of Huray's snowball model with an explicit temperature dependence is proposed to achieve highquality on-package interconnect loss correlation at different temperatures.
The time of onset of intradialytic hypotension during a hemodialysis session associates with clinical parameters and mortality (2021)

Intradialytic hypotension (IDH) is a common complication of hemodialysis, but there is no data about the time of onset during treatment. Here we describe the incidence of IDH throughout hemodialysis and associations of time of hypotension with clinical parameters and survival by analyzing data from 21 dialysis clinics in the United States to include 785682 treatments from 4348 patients. IDH was defined as a systolic blood pressure of 90 mmHg or under while IDH incidence was calculated in 30-minute intervals throughout the hemodialysis session. Associations of time of IDH with clinical and treatment parameters were explored using logistic regression and with survival using Cox-regression. Sensitivity analysis considered further IDH definitions. IDH occurred in 12% of sessions at a median time interval of 120-149 minutes. There was no notable change in IDH incidence across hemodialysis intervals (range: 2.6-3.2 episodes per 100 session-intervals). Relative blood volume and ultrafiltration volume did not notably associate with IDH in the first 90 minutes but did thereafter. Associations between central venous but not arterial oxygen saturation and IDH were present throughout hemodialysis. Patients prone to IDH early as compared to late in a session had worse survival. Sensitivity analyses suggested IDH definition affects time of onset but other analyses were comparable. Thus, our study highlights the incidence of IDH during the early part of hemodialysis which, when compared to later episodes, associates with clinical parameters and mortality.
Structure‐activity relationships of eighteen somatostatin analogues on gastric secretion. (1978)

1. The effect of somatostatin and eighteen somatostatin analogues on pentagastrin-stimulated gastric acid and pepsin secretion was investigated in the conscious vagotomized cat prepared with chronic gastric fistulae. The majority of the analogues are peptides where D-amino acids are incorporated into the molecule instead of the natural L-isomers. 2. The ID50 for cyclic-somatostatin inhibition of near-maximal gastric acid secretion stimulated by pentagastrin 8 microgram kg-1 hr-1 was found to be 1.29 +/- 0.13 n-mole kg-1 hr-1. Pentagastrin-stimulated pepsin secretion had a lower threshold to somatostatin inhibition than did acid secretion. 3. D-Phe6, D-Phe7, D-Thr10, D-Thr12 and D-Phe6-D-Trp8 analogues all show low biological activity against the secretion of gastric acid and pepsin, growth hormone, insulin and glucagon. None of these analogues are antagonists of the cyclic-somatostatin inhibition of gastric secretion, suggesting that they have low affinity for this somatostatin receptor. 4. The analogues under investigation show parallel changes in activity against gastric and growth hormone secretion, suggesting a similarity between the gastric and growth hormone receptors for somatostatin. 5. D-Cys14 analogues are equipotent with or have a greater potency than cyclic-simatostatin in inhibiting the secretion of gastric acid, growth hormone and glucagon but show low insulin inhibiting activity.
Contribution of large-scale motions to the skin friction in a moderate adverse pressure gradient turbulent boundary layer (2018)

Direct numerical simulation of a turbulent boundary layer (TBL) subjected to a moderate adverse pressure gradient (APG, $\unicode[STIX]{x1D6FD}=1.45$ ) is performed to explore the contribution of large scales to the skin friction, where $\unicode[STIX]{x1D6FD}$ is the Clauser pressure gradient parameter. The Reynolds number based on the momentum thickness develops from $Re_{\unicode[STIX]{x1D703}}\approx 110$ to 6000 with an equilibrium region in $Re_{\unicode[STIX]{x1D703}}=4000$ –5500. The spanwise wavelength ( $\unicode[STIX]{x1D706}_{z}$ ) spectra of the streamwise and spanwise velocity fluctuations show that the large-scale energy is significantly enhanced throughout the boundary layer. We quantify the superposition and amplitude modulation effects of these enhanced large scales on the skin friction coefficient ( $C_{f}$ ) by employing two approaches: (i) spanwise co-spectra of $\langle v\unicode[STIX]{x1D714}_{z}\rangle$ and $\langle -w\unicode[STIX]{x1D714}_{y}\rangle$ ; (ii) conditionally averaged $\langle v\unicode[STIX]{x1D714}_{z}\rangle$ and $\langle -w\unicode[STIX]{x1D714}_{y}\rangle$ . The velocity–vorticity correlations $\langle v\unicode[STIX]{x1D714}_{z}\rangle$ and $\langle -w\unicode[STIX]{x1D714}_{y}\rangle$ are related to the advective transport and the vortex stretching, respectively. Although $\langle v\unicode[STIX]{x1D714}_{z}\rangle$ negatively contributes to $C_{f}$ , the positive contribution of the large scales ( $\unicode[STIX]{x1D706}_{z}&gt;0.5\unicode[STIX]{x1D6FF}$ ) is observed in the co-spectra of weighted $\langle v\unicode[STIX]{x1D714}_{z}\rangle$ . For the co-spectra of weighted $\langle -w\unicode[STIX]{x1D714}_{y}\rangle$ , we observe an outer peak at $\unicode[STIX]{x1D706}_{z}\approx 0.75\unicode[STIX]{x1D6FF}$ and the superposition of the large scales in the buffer region, leading to the enhancement of $C_{f}$ . The magnitude of $\langle v\unicode[STIX]{x1D714}_{z}\rangle$ and $\langle -w\unicode[STIX]{x1D714}_{y}\rangle$ depends on the large-scale streamwise velocity fluctuations ( $u_{L}$ ). In particular, the negative- $u_{L}$ events amplify $\langle v\unicode[STIX]{x1D714}_{z}\rangle$ in the outer region, and $\langle -w\unicode[STIX]{x1D714}_{y}\rangle$ is enhanced by the positive- $u_{L}$ events. As a result, the skin friction induced by $\langle v\unicode[STIX]{x1D714}_{z}\rangle$ and $\langle -w\unicode[STIX]{x1D714}_{y}\rangle$ increases in the present APG TBL.
Multiphase Voltage-Mode Hysteretic Controlled DC–DC Converter With Novel Current Sharing (2004)

Today's on-board high-density, low-output-voltage, high-output-current, fast transient point-of-load (POL) dc-dc converters design requirements for the new generation of integrated circuits, digital signal processors, and microprocessors are increasingly becoming stricter than ever. This is due to the demand for high dynamic performance dc-dc conversion with tight dynamic tolerances for supply voltages coupled with very high power density. In this paper, a multiphase voltage-mode hysteretic controlled POL dc-dc converter with new current sharing is presented. Theoretical analysis is provided for multiphase and interleaved dc-dc converters with new current sharing method. The simulation and experimental results are compared based on a specific design example.
Successful treatment of pure red cell aplasia in systemic lupus erythematosus with erythropoietin. (1995)

We describe a 32-year-old woman who developed severe anemia due to pure red cell aplasia in the course of systemic lupus erythematosus (SLE). After failure of therapy with high doses of glucocorticoids and immunoglobulins, and despite high levels of endogenous erythropoietin, she was treated with human recombinant erythropoietin with dramatic and sustained improvement. Based on this case and on the literature review of erythropoietin therapy in pure red cell aplasia, we suggest that erythropoietin should be used in SLE associated pure red cell aplasia before cytotoxic therapy.
Fusion: a system for business users to manage program variability (2005)

In order to make software components more flexible and reusable, it is desirable to provide business users with facilities to assemble and control them without their needing programming knowledge. This paper describes a fully functional prototype middleware system where variability is externalized so that core applications need not be altered for anticipated changes. In this system, application behavior modification is fast and easy, making this middleware suitable for frequently changing programs.
A new nonlinear dc model for HBT and mesfet power devices (1995)

Abstract A new nonlinear empirical model that can be applied to the collector current source of power HBT devices and to the drain current source of power MESFETs is presented. The model includes the self‐heating effects present in both HBT and MESFET devices. It also accurately predicts the slope variation of the dc‐I‐V characteristics from positive to negative, which occurs in MESFET devices. The proposed model is validated with the measured dc and small‐signal characteristics of one HBT and one MESFET medium‐power device. Good agreement between measurement and simulation results was obtained for both devices. © 1995 John Wiley &amp; Sons, Inc.

Self-Consistent Model of Light-Induced Molecular Motion Around Metallic Nanostructures (2010)

Azobenzene derivatives containing polymers deform when exposed to light with a wavelength in the principle absorption band associated with trans−cis isomerization of the azobenzene derivative molecule. When such polymers cover a metallic nanoparticle exposed to light near its surface plasmon resonance, which also happens to overlap with the azobenzene derivative absorption band, the resulting surface deformations are a novel measure or probe of the plasmonic near-field intensities. We developed a self-consistent model of the process by combining a Monte Carlo based model for the absorption and subsequent light-induced mass transport of the polymer with finite difference time domain computations of the electromagnetic fields around the nanoparticle that induce the absorption. The resulting self-consistent approach is shown to describe the key features of experimental observations concerning silver disk nanoparticles.
Feasibility of robot-assisted radical prostatectomy for very-high risk prostate cancer: surgical and oncological outcomes in men aged ≥70 years (2014)

RALP-PLND is a feasible option for VHPCa in elderly patients with satisfactory oncologic outcomes; however, functional outcomes were not as favorable. Patients who are unable to accept the risk of adjuvant therapy and its side effects or incontinence should be deterred from surgical treatment, and other options such as radiation therapy could be an alternative.

Improved ON-State Reliability of Atom Switch Using Alloy Electrodes (2013)

Cu-alloy active-electrode coupled with Ru-alloy inert electrode is proposed to improve the ON-state reliability of nonvolatile Cu atom switch. The high rupture temperature (T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> > 400 °C) of the nanometer-scale Cu bridge with high thermal resistance (R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sub> ) is realized by the Cu(AlTi)-alloy without increasing programming current. The anti-Cu diffusive Ru(Ta) alloy contributes to improve the retention of the ON-state at 150 °C and endurance to > 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> cycles. The metallurgical prescription on the electrodes is a key to improve the stability of the nanometer-scale conducting bridge while keeping the switching power low.
Two-Dimensional WSe2/MoS2 p–n Heterojunction-Based Transparent Photovoltaic Cell and Its Performance Enhancement by Fluoropolymer Passivation (2018)

As a means to overcome the limitation of installation space and to promote the utilization of the solar cell in various applications, a transparent thin-film solar cell has been studied by many researchers. To achieve a transparent solar cell, the choice of materials which are transparent enough and showing the photovoltaic property at the same time is the key. Here, we suggest a two-dimensional (2D) p-n heterojunction of WSe<sub>2</sub>/MoS<sub>2</sub> and an indium tin oxide electrode to fabricate a transparent thin-film photovoltaic cell. Because of advantages that 2D materials possess, a highly transparent (∼80%) solar cell with considerable efficiency was achieved. Furthermore, by introducing a transparent passivation layer composed of a fluoropolymer, the photovoltaic performance was much improved. With the passivation layer, our WSe<sub>2</sub>/MoS<sub>2</sub> transparent photovoltaic cell reached an efficiency of ∼10%. A comparison of photovoltaic parameters before and after applying passivation and analysis on the origin of such differences are also discussed. To the best of our knowledge, this is the first report to fabricate a 2D material-based fully transparent photovoltaic device. Our result exhibits a great potential of the van der Waals p-n heterojunction of 2D semiconductors to be utilized for an active layer of a highly transparent and lightweight thin-film solar cell.
Microbubbles as a scattering contrast agent for grating-based x-ray dark-field imaging (2013)

In clinically established-absorption-based-biomedical x-ray imaging, contrast agents with high atomic numbers (e.g. iodine) are commonly used for contrast enhancement. The development of novel x-ray contrast modalities such as phase contrast and dark-field contrast opens up the possible use of alternative contrast media in x-ray imaging. We investigate using ultrasound contrast agents, which unlike iodine-based contrast agents can also be administered to patients with renal impairment and thyroid dysfunction, for application with a recently developed novel x-ray dark-field imaging modality. To produce contrast from these microbubble-based contrast agents, our method exploits ultra-small-angle coherent x-ray scattering. Such scattering dark-field x-ray images can be obtained with a grating-based x-ray imaging setup, together with refraction-based differential phase-contrast and the conventional attenuation contrast images. In this work we specifically show that ultrasound contrast agents based on microbubbles can be used to produce strongly enhanced dark-field contrast, with superior contrast-to-noise ratio compared to the attenuation signal. We also demonstrate that this method works well with an x-ray tube-based setup and that the relative contrast gain even increases when the pixel size is increased from tenths of microns to clinically compatible detector resolutions about up to a millimetre.
Structural Organization and Zn2+-dependent Subdomain Interactions Involving Autoantigenic Epitopes in the Ring-B-box-Coiled-coil (RBCC) Region of Ro52 (2005)

Ro52 is one of the major autoantigens targeted in the autoimmune disease Sjögren syndrome. By sequence similarity, Ro52 belongs to the RING-B-box-coiled-coil (RBCC) protein family. Disease-related antibodies bind Ro52 in a conformation-dependent way both in the coiled-coil region and in the Zn2+-binding Ring-B-box region. Primarily associated with Sjögren syndrome, Ro52 autoantibodies directed to a specific, partially structured epitope in the coiled-coil region may also induce a congenital heart block in the fetus of pregnant Ro52-positive mothers. To improve our understanding of the pathogenic effects of autoantibody binding to the Zn2+-binding region, a multianalytical mapping of its structural, biophysical, and antigenic properties is presented. Structure content and ligand binding of subregions, dissected by peptide synthesis and subcloning, were analyzed by fluorescence and circular dichroism spectroscopy. A novel matrix-assisted laser desorption ionization time-of-flight mass spectrometry strategy for time-resolved proteolysis experiments of large protein domains was developed to facilitate analysis and to help resolve the tertiary arrangement of the entire RBCC subregion. The linker region between the RING and B-box motifs is crucial for full folding, and Zn2+ affinity of the RING-B-box region is further protected in the entire RBCC region and appears to interact with the coiled-coil region. Murine monoclonal antibodies raised toward the RING-B-box region were primarily directed toward the linker, further supporting a highly functional role for the linker in a cellular environment. Taken together with our previous analysis of autoantigenic epitopes in the coiled-coil region, localization of autoantigenic epitopes in Ro52 appears closely related to molecular functionalities.
