Thermal and Electrical Conductivities of Nanocrystalline Nickel Microbridges (2012)

DC electrical self-heating (Joule heating) is exploited to characterize the thermal behavior of Ni microbridges. The temperature rise of the devices due to self-heating is monitored using an infrared microscope for current densities up to 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</sup> A/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The obtained temperature profiles reveal significant heating at the bases of the microbridges. Simulations are performed in order to extract the thermal conductivity of the electroplated Ni thin film from the experimental data. The thermal conductivity is found to be 78.8 W/m · K or 13% less than that of bulk Ni. As current flows through the microbridges, they deflect upward, significantly changing the system response and pull-in voltage required for actuation. Additionally, the electrical resistivity and specific electrical contact resistances between the microbridges and the anchor points are reported. The electroplated Ni is found to have an electrical resistivity of 9.7 μΩ · cm which agrees with other values in the literature for thin-film Ni. By combining the electrical and thermal measurements, it is possible to determine the phonon and electron contributions to thermal conductivity. Although demonstrated on Ni films, this technique can be applied to any metallic film without modification. Such characterization of transport properties of constituent materials is important in the modeling of microelectromechanical systems and enables device performance to be predicted with improved accuracy.
The Effect of Unilateral Mean Luminance on Binocular Combination in normal and amblyopic vision (2013)

Luminance plays a modulating role in the processes of several visual tasks, which in turn provides significant information for the understanding of visual processing. Here, using a binocular phase combination paradigm, we studied the effect of unilateral changes in mean luminance on binocular combination in both normal and amblyopic vision. We found, in normal observers, attenuation of one eye's stimulus luminance with neutral density filters produces binocular phase combination similar to those of amblyopic subjects. Correspondingly, in amblyopic observers, reduction of the fellow eye's stimulus luminance produces binocular phase combination similar to those of normal subjects. These phenomena could be explained by an attenuated contribution of the filtered eye to the binocular phase percept due to reduced gain-control. The findings have major implications both for the study of binocular combination and for amblyopia treatment.

Derivations of homotopy algebras (2013)

We recall the definition of strong homotopy derivations of $A_\infty $ algebras and introduce the corresponding definition for $L_\infty $ algebras. We define strong homotopy inner derivations for both algebras and exhibit explicit examples of both.
Using 5G QoS Mechanisms to Achieve QoE-Aware Resource Allocation (2021)

Network operators generally aim at providing a good level of satisfaction to their customers. Diverse application demands require the usage of beyond best-effort resource allocation mechanisms, particularly in resource-constrained environments. Such mechanisms introduce additional complexity in the control plane and need to be configured appropriately. Within 5G mobile networks, two new mechanisms for QoS-aware resource allocation are introduced. While QoS Flows enable specifying various QoS profiles on a per flow granularity, slices are dedicated virtual networks, strongly isolated against each other, with aggregated QoS guarantees. It is, however, unclear how QoS Flows and network slicing can optimally be exploited to ensure a high customer QoE while efficiently utilizing the available network resources. We address this research question and evaluate the outlined interplay using the OMNeT++ simulation environment in a multi-application scenario. We show that resource isolation induced by slicing may negatively affect application quality or system utilization, and that this impact can be overcome by finetuning the system parameters.
Functional Synergy between CD40 Ligand and HIV-1 Tat Contributes to Inflammation: Implications in HIV Type 1 Dementia (2007)

HIV type 1 (HIV-1)-associated dementia (HAD) is believed to occur due to aberrant activation of monocyte-derived macrophages and brain-resident microglial cells by viral proteins as well as by the proinflammatory mediators released by infected cells. To investigate the inflammatory aspects of the disease, we examined the levels of soluble CD40L (sCD40L) in paired samples of plasma and cerebrospinal fluid obtained from 25 HIV-infected individuals. A significantly higher level of sCD40L was detected in both cerebrospinal fluid and plasma from HIV-infected patients with cognitive impairment, compared with their nonimpaired counterparts. The contribution of sCD40L to the pathogenesis of HAD was then examined by in vitro experiments. rCD40L synergized with HIV-1 Tat to increase TNF-alpha release from primary human monocytes and microglia, in an NF-kappaB-dependent manner. The mechanistic basis for this synergism was attributed to a Tat-mediated up-regulation of CD40 in monocytes and microglia. Finally, the CD40L-mediated increase in TNF-alpha production by monocytes was shown to be biologically important; immunodepletion experiments revealed that TNF-alpha was essential for the neurotoxic effects of conditioned medium recovered from Tat/CD40L-treated monocytes. Taken together, our results show that CD40 signaling in microglia and monocytes can synergize with the effects of Tat, further amplifying inflammatory processes within the CNS and influencing neuronal survival.
Use of Polymers as Protecting Groups in Organic Synthesis. VII. Preparation of Monobenzoates of Acyclic Triols (1978)

Abstract Crosslinked resins containing styrylboronic acid units were used in the protection of 1,2 and 1,3‐diol groupings with several acyclic triols. With 1,2,3‐propanetriol, a five‐membered ring boronate was formed almost exclusively while with 1, 2, 4‐butanetriol a six‐membered ring boronate predominated. The fully recyclable polymer could be used in a fast and efficient synthesis of monobenzoyl derivatives of triols. Macroreticular and 1% crosslinked solvent‐swellable resins were tested and the latter were found to perform better on repeated use.
Instability of partially disordered carbon-doped AlGaAs/GaAs superlattices (1990)

Superlattices of Al0.3Ga0.7As/GaAs grown by metalorganic chemical vapor deposition and heavily doped with carbon using CCl4 were annealed for 24 h at 825 °C under a variety of ambient and surface encapsulation conditions. Pronounced changes in photoluminescence from the annealed superlattices with storage time at room temperature, as opposed to an excellent reproducibility of that from the as-grown, not annealed samples, are reported. These changes may be indicative of degraded thermal stability of the annealed superlattice crystals due to high-temperature-induced lattice defects. The systematic failure to fabricate buried-heterostructure quantum well lasers via impurity-induced layer disordering in similarly doped AlGaAs/GaAs crystals, which may be related to the same effect, is also discussed.
Synthesis and DNA-binding properties of water-soluble cationic pyropheophorbides derived from chlorophyll a/b (2009)

A series of mono-, di-, tetra- and hexacationic esters of pyropheophorbide a/b have been designed and synthesized to explore the intercalation of their phorbine ring between the base pairs of double-helical DNA and the influence of their peripheral substituents on the DNA interactions. Mono-(1), di-(2, 3) and tetra-(4, 5) cationic pyropheophorbides are soluble as an oligomeric aggregate in HEPES buffer, but hexa-(6) cationic pyropheophorbide is soluble as a monomer at lower concentrations. The interaction of these cationic pyropheophorbide derivatives with DNA has been investigated by DNA unwinding assay, fluorescence energy transfer, and measurements of the melting temperature of the double-helical DNA and visible absorption spectra. Dicationic 2 and 3 bind outside the double-helical DNA without and/or with self-aggregation and with self-aggregation, respectively, because they cannot intercalate between the base-pairs due to their aggregation. On the other hand, tetracationic 4 and 5 and hexacationic 6 intercalate between the base pairs of the double-helical DNA. The binding mode of the cationic pyropheophorbides a/b is strongly dependent on the number and position of the cationic peripheral substituents of the pyropheophorbides.

Origin of the visible emission of black silicon microstructures (2015)

Silicon, the mainstay semiconductor in microelectronics, is considered unsuitable for optoelectronic applications due to its indirect electronic band gap that limits its efficiency as light emitter. Here, we univocally determine at the nanoscale the origin of visible emission in microstructured black silicon by cathodoluminescence spectroscopy and imaging. We demonstrate the formation of amorphous silicon oxide microstructures with a white emission. The white emission is composed by four features peaking at 1.98 eV, 2.24 eV, 2.77 eV, and 3.05 eV. The origin of such emissions is related to SiOx intrinsic point defects and to the sulfur doping due to the laser processing. Similar results go in the direction of developing optoelectronic devices suitable for silicon-based circuitry.

Field emission behavior of boron nitride nanotubes (2017)

The field emission properties of boron nitride nanotube (BNNT) field emitters according to vacuum pressure were demonstrated. During the short-term emission operation, the field emission behaviors were almost similar, regardless of the vacuum pressure, even though the turn-on electric field of the BNNT field emitter was slightly increased as the vacuum pressure increased. On the other hand, during the long-term emission operation, both the degradation and fluctuations of the emission current of the BNNT field emitters were dramatically increased as the vacuum pressure increased. The degradation of field emission properties of the BNNT emitters according to vacuum pressure is mainly attributed to the ion bombardment effect, rather than the oxidation effect. The field emission behavior under Ar ambient also strongly demonstrates that the degradation and the fluctuation of the emission current are largely dependent on the ion bombardment effect.
Pultruded fiber reinforced blocked polyurethane (PU) composites. I. Processability and mechanical properties (1992)

Abstract This paper presents a proprietary process developed to manufacture polyurethane (PU) pultruded composites. The blocked isocyanate (NCO)‐terminated PU prepolymer synthesized in this study was prepared from ε‐caprolactam blocked blends of toluene diisocyanate (TDI) and branched polyester. The processability and mechanical properties of various fibers (glass, carbon, and Kevlar 49 aramid fiber) reinforced PU composites have been studied. From the investigation of the pot life of resins, the reactivity of resins, and fiber wet‐out, it was found that the blocked PU prepolymers with chain extender showed excellent processability for pultrusion. Results show that the mechanical properties (i.e., tensile strength, specific tensile strength, flexural strength, specific flexural strength, flexural modulus, and impact strength) increase with fiber content. Kevlar fiber/PU composites possess the highest impact strength and specific tensile strength, whereas carbon fiber/PU composites show the highest tensile strength, flexural strength, specific flexural strength, and flexural modulus. Experimental results of tensile strength of all composites except carbon fiber/PU composites follow the rule of mixtures. The deviation of property of carbon fiber/PU composite is due to fiber breakage during processing. Pultruded fiber reinforced PU composites showed excellent tensile and impact strength compared to other pultruded composites studied.

Thermal Noise Response Based Static Non-Contact Atomic Force Microscopy (2004)

Micro-cantilever based devices have revolutionized imaging and they are the primary tools for investigation and control of matter at the nanoscale. In this paper a novel approach based on the thermal noise response of the cantilever is developed that makes non-contact AFM possible in static mode. This technique exploits the dependence of cantilever’s resonant frequency on the tipsample separation to maintain a small tip-sample separation by regulating the equivalent resonant frequency. The resonant frequency is estimated from cantilever’s response to the thermal noise. The experiments performed in ambient room conditions have achieved tipsample separations as small as 4 nm for time periods in excess of 20 min. Based on this control technique a new static non-contact mode operation of AFM has been demonstrated. This method has given rise to an extremely powerful non-contact imaging technique capable of detecting sub-angstorm features at a bandwidth of 200 Hz with a force sensitivity of a few pN.
Improving the Flexural Strength Test of Brushite Cement (2014)

In the investigation of mechanical properties, calcium phosphate cements exhibit large sample-to-sample deviation due to its porous nature, possibility of unhomogenous distribution and small specimen size. This situation generates difficulties for obtaining accurate results and creates an obstacle for testing different composition where only a small batch size is available. In this respect, specimen shape, whether being injected, porosity ratio, surface quality, bearing support design have significant matter on variability in terms of three-and four-point bending test. Therefore, different methods have been studied to reduce variability with a simpler material preparation than common methods on injected and moulded cement. The entire comparison is made with the consideration of three-and four-point bending testing, the eccentric loading error calculation with engineering calculation software “Mathcad 15”, porosity measurement with Archimedes method, microstructure investigation on Scanning Electron Microscope (SEM), macro-porosity distribution measurement by Micro CT Scanner.

Isolation, characterization and in vitro mitogenic stimulation of peripheral blood lymphocytes from an American buffalo. (1989)

A rapid and reproducible method is described for the isolation and characterization of leukocytes from the peripheral blood of an American buffalo (bison). Centrifugation of the buffy coat cells on a Percoll gradient (1.079 g/mL) at 650 x g for 20 min resulted in the separation and high yields of pure viable leukocytes. The sheep erythrocyte-rosetting technique (ER) showed that 59% of the cells were ER+ (T lymphocytes). Fluorescein isothiocyanate (FITC)-conjugated peanut agglutinin and FITC-conjugated concanavalin A revealed 77% and 89% positive cells, respectively. The isolated leukocytes contained adherent accessory cells and functionally active T and B lymphocytes which proliferated in response to both T and B cell mitogens and to exogenous recombinant bovine interleukin-2 in the absence and/or presence of the thiol compound 2-mercaptoethanol.
Learning and Tracking the 3D Body Shape of Freely Moving Infants from RGB-D sequences (2019)

Statistical models of the human body surface are generally learned from thousands of high-quality 3D scans in predefined poses to cover the wide variety of human body shapes and articulations. Acquisition of such data requires expensive equipment, calibration procedures, and is limited to cooperative subjects who can understand and follow instructions, such as adults. We present a method for learning a statistical 3D Skinned Multi-Infant Linear body model (SMIL) from incomplete, low-quality RGB-D sequences of freely moving infants. Quantitative experiments show that SMIL faithfully represents the RGB-D data and properly factorizes the shape and pose of the infants. To demonstrate the applicability of SMIL, we fit the model to RGB-D sequences of freely moving infants and show, with a case study, that our method captures enough motion detail for General Movements Assessment (GMA), a method used in clinical practice for early detection of neurodevelopmental disorders in infants. SMIL provides a new tool for analyzing infant shape and movement and is a step towards an automated system for GMA.
Adaptive driving of synchronous rectifier for LLC converter without signal sensing (2013)

This paper presents the novel driving technique of synchronous rectifier (SR) for the LLC converter. The unique characteristic of “Vo*D=constant” of LLC converter is utilized to predict optimal duty ratio D, where D is the conduction period of secondary diode. This technique does not need the sensing of SR current neither SR voltage. Additionally, the auto tuning technique is implemented to adjust the duty ratio precisely as well by digital control using TI's DSP of Piccolo TMS320F28027. The technique is confirmed by experimentally..
Wireline–Wireless Convergence (2020)

Abstract Virtualization and the development of the 5G architecture, i.e. a 5GCore (5GC) capable to serve a great variety of Access Networks have triggered the industry to work on Wireless–Wireline convergence. As opposed to previous attempts that were focusing on convergence at policy control level, the 5GC‐based solution focuses on defining an interworking function, the Wireline Access Gateway Function (W‐AGF), that terminates the legacy Wireline Access interface on one of its sides and the 5GC interfaces N1/N2/N3 on its other side. This architecture enables the 5GC to serve Residential Gateways modified to support 5G protocols and procedures (5G RG) but also legacy unmodified Fixed Network Residential Gateways (FN RG). 5G RG can benefit of slicing as defined for 5GC but also of a Hybrid Access where 5G RG are simultaneously connected via 3GPP radio and via Wireline Access, ensuring thus higher throughput and reliability for the traffic of the customer premises. Fixed Wireless Access (5G RG connection via 3GPP radio) enables flexible deployment of a mobile RG (e.g. in public transport or for short‐lived events). A 5G RG and its Wireline Access interworking function, the W‐AGF, can together be used as a trusted non‐3GPP AN serving 3GPP User Equipment (smartphone) with managed Quality of Service and accurate location information (e.g. for home‐based charging). The Broadband Forum (BBF) and 3GPP deliver a first release of the corresponding specifications for March 2020 (3GPP R16) that will likely be improved in the next release (3GPP R17).

COX-2 inhibitors and cardiovascular risk. Inferences based on biology and clinical studies. (2006)

Even though non-steroidal anti-inflammatory drugs (NSAIDs) have been widely used for a long time, the search continues for anti-inflammatory drugs with few side-effects. COX-2 inhibitors are currently most debated, because they have less gastrointestinal side effects but have been linked to increased cardiovascular morbidity and mortality, presumably related to thrombotic events. This has brought about the withdrawal of rofecoxib and other COX-2 inhibitors from the market. Although the results of several large studies with prospective, randomized design and meta-analysis of different trials have led to the demise of many popular COX-2 inhibitors, yet the conclusion seems to be rather simplistic. This review presents evidence from basic biology and clinical studies with the expectation that a balanced position, particularly in relation to increase in cardiovascular events, may be elucidated.
Unprecedented Reversal of Regioselectivity during Methanolysis and an Interception of Curtius Rearrangement (2021)

Abstract Unprecedented reversal in regioselectivity during methanolysis of anhydrides due to the change in substitution pattern of fluorine in the phenyl moiety, and the formation of nitrene intercepted intermediates during Curtius rearrangement of the acids were the major impediments for discovering bioactive molecules in beta amyloid cleaving enzyme‐1 (BACE1) program. Solutions to these synthetic challenges, and our investigation into this unexpected change in reactivity are discussed.
