Flexible photovoltaic power systems: integration opportunities, challenges and advances (2017)

Photovoltaic power systems, consisting of solar modules, energy storage, and power management electronics, are of great importance for applications ranging from off-grid and portable power to ambient light harvesting for sensor nodes. Co-design and integration of the components using printing and coating methods on flexible substrates enable the production of effective and customizable systems for these diverse applications. In this article, we review photovoltaic module and energy storage technologies suitable for integration into flexible power systems. We discuss the design of electrical characteristics for these systems that enable them to power desired loads efficiently, as well as strategies for physically combining the components. Functions and design considerations of power management electronics are presented along with recent progress toward printed and flexible power electronics. We analyze both hybrid and fully flexible photovoltaic systems and the critical role of the application in the choices of materials and architectures for the system components.
A voltage-fed series load resonant high frequency inverter with ZCS-PDM scheme for induction-heated fusing roller and extended circuit topologies (2006)

This paper presents the two lossless auxiliary inductors-assisted voltage source type half bridge (single ended push pull: SEPP) series resonant high frequency inverter for induction heated fusing roller in copy and printing machines. The simple high-frequency inverter treated here can completely achieve stable zero current soft switching (ZCS) commutation for wide its output power regulation ranges and load variations under constant high frequency pulse density modulation (PDM) scheme. Its transient and steady state operating principle is originally described and discussed for a constant high-frequency PDM control strategy under a stable ZCS operation commutation, together with its output effective power regulation characteristics-based on the high frequency PDM strategy. The experimental operating performances of this voltage source SEPP ZCS-PDM series resonant high frequency inverter using IGBTs are illustrated as compared with computer simulation results and experimental ones. Its power losses analysis and actual efficiency are evaluated and discussed on the basis of simulation and experimental results. The feasible effectiveness of this high frequency inverter appliance implemented here is proved from the practical point of view.
Gender, Business Education, Family Background and Personal Traits; a Multi Dimensional Analysis of Their Affects on Entrepreneurial Propensity: Findings from Turkey (2011)

This study aims to reveal the effects of personality traits such as proactivity, internal locus of control, and the need for achievement as well as gender, business education, and family entrepreneurship, if any, on an individual’s propensity to entrepreneurship, and the power of these effects. Carried out on 175 business administration students in Turkey, Ankara, the study has found that personality traits do increase entrepreneurial intentions, which are affected more by internal locus of control than any other factor, but that gender, family business, and business education make no difference on an individual’s propensity to entrepreneurship.
Stringing up the Pearls:  Self-Assembly, Optical and Electronic Properties of CdSe− and Au−LiMo<sub>3</sub>Se<sub>3</sub> Nanoparticle−Nanowire Composites (2002)

Chevrel-type LiMo3Se3 nanowires dissolved in dimethyl sulfoxide were decorated with 13 nm citrate ligated Au particles (water) and 6 nm trioctylphosphineoxide ligated CdSe particles (tetrahydrofuran) by combining the respective solutions at room temperature, followed by mild acidification with hydrochloric acid in the case of Au. The morphology of the formed nanostructured Au−LiMo3Se3 and CdSe−LiMo3Se3 aggregates depends on stoichiometry and reaction conditions. While the UV/vis spectra of the aggregates are largely the sum of the subspectra of the building blocks, the emission spectra of the CdSe−LiMo3Se3 material reveal quenching of CdSe based photoluminescence. The electrical conductance of 5 nm thick films obtained by drying solutions of the composites decreases with increasing temperature, which shows that the nanowires remain metallic after binding of the nanoparticles.
Superpulse CO<sub>2</sub> laser treatment of facial syringomata (1987)

Eight patients with facial syringomata have been treated with the superpulse CO2 laser and followed for periods up to 3 years. Superpulse capability allows satisfactory photovaporization of overlying skin and exposure and liberation of the underlying cyst. Healing was satisfactory with minimal scarring and no persistence or recurrence of syringomata in five of eight cases.

Hydro‐mechanical modeling of cohesive crack propagation in multiphase porous media using the extended finite element method (2012)

SUMMARY In this paper, a numerical model is developed for the fully coupled hydro‐mechanical analysis of deformable, progressively fracturing porous media interacting with the flow of two immiscible, compressible wetting and non‐wetting pore fluids, in which the coupling between various processes is taken into account. The governing equations involving the coupled solid skeleton deformation and two‐phase fluid flow in partially saturated porous media including cohesive cracks are derived within the framework of the generalized Biot theory. The fluid flow within the crack is simulated using the Darcy law in which the permeability variation with porosity because of the cracking of the solid skeleton is accounted. The cohesive crack model is integrated into the numerical modeling by means of which the nonlinear fracture processes occurring along the fracture process zone are simulated. The solid phase displacement, the wetting phase pressure and the capillary pressure are taken as the primary variables of the three‐phase formulation. The other variables are incorporated into the model via the experimentally determined functions, which specify the relationship between the hydraulic properties of the fracturing porous medium, that is saturation, permeability and capillary pressure. The spatial discretization is implemented by employing the extended finite element method, and the time domain discretization is performed using the generalized Newmark scheme to derive the final system of fully coupled nonlinear equations of the hydro‐mechanical problem. It is illustrated that by allowing for the interaction between various processes, that is the solid skeleton deformation, the wetting and the non‐wetting pore fluid flow and the cohesive crack propagation, the effect of the presence of the geomechanical discontinuity can be completely captured.

Congestion-Aware Rate Adaptation in Wireless Networks: A Measurement-Driven Approach (2008)

Traditional rate adaptation solutions for IEEE 802.11 wireless networks perform poorly in congested networks. Measurement studies show that congestion in a wireless network leads to the use of lower transmission data rates and thus reduces overall network throughput and capacity. The lack of techniques to reliably identify and characterize congestion in wireless networks has prevented development of rate adaptation solutions that incorporate congestion information in their decision framework. To this end, our main contributions in this paper are two-fold. First, we present a technique that identifies and measures congestion in an 802.11 network in real time. Second, we design Wireless congestion Optimized Fallback (WOOF), a measurement-driven rate adaptation scheme for 802.11 devices that uses the congestion measurement to identify congestion related packet losses. Through experimental evaluation, we show that WOOF achieves up to 300% higher throughput in congested networks, compared to other well-known adaptation algorithms.
Improvement of Hydrogenated Amorphous Silicon n-i-p Diode Performance by H<sub>2</sub> Plasma Treatment for i/p Interface (1990)

Hydrogenated amorphous silicon (a-Si:H) n-i-p diodes in which the intrinsic (i-type) layer surfaces were exposed to an H 2 plasma before depositing the p-type layer (H 2 plasma treatment of the i/p interface) were prepared. The effects of this H 2 plasma treatment of the i/p interface were observed by dark I - V , photo- I - V under 450 nm illumination, and quasistatic C - V measurements. It has been found that the defect density at the i/p interface is reduced by this treatment. It has also been determined that the performance of a-Si:H diodes is improved by this treatment of the interface.
Poison oak hyposensitization. Evaluation of purified urushiol (1974)

More than 500 volunteers were patch tested with dilutions of purified poison oak urushiol in acetone. Of this group, 69 subjects participated in three experiments that conclusively showed that large amounts of urushiol taken over a period of three or more months produced measurable hyposensitization, as detected by repeated patch testing. No systemic toxicity was observed, but pruritus ani was common, and occasional skin eruptions were seen when too much drug was given. These cutaneous symptoms and signs disappeared once the subject had become hyposensitized.
Catalyst-Feedstock-Engineering Interactions in Fluid Catalytic Cracking (1978)

Abstract Fossil fuels, amassed over eons of geologic prehistory, are being irreversibly depleted about 106 times more rapidly than they were formed. With this sort of kinetics, there is little question that there exists, in the ultimate sense, an energy crisis [1–3]. That is, there will be fuel deficits for whatever time interval declining volumes of hydrocarbon reserves are not compensated for by increased supply from new energy sources such as nuclear, solar, and geothermal. In the interim period, the petroleum refiner is forced to utilize higher molecular weight, more hydrogen-deficient crudes, and crude fractions which have higher concentrations of impurities. Eventually, substantial quantities of “synthetic crudes” derived from coal, oil shale, tar sands, and bitumens may also become available.
Enhanced endothelium derived hyperpolarising factor activity in resistance arteries from normal pressure glaucoma patients: implications for vascular function in the eye (2005)

The enhanced contribution of EDHF to ACh mediated relaxation in systemic resistance arteries from NPG patients may contribute to the maintained endothelium mediated relaxation in these vessels. EDHF also contributes significantly to bradykinin mediated relaxation in porcine ocular ciliary arteries. Therefore, similar changes in the balance of relaxing factors in the ocular circulation could influence the response of the eye to vascular endothelial dysfunction in NPG.
Platelet‐derived growth factor potentiates cellular responses of articular chondrocytes to interleukin‐1 (1991)

Recombinant human interleukin-1 alpha (IL-1 alpha) induced a time-dependent (0-72 hours) and concentration-dependent (0.01-10 ng/ml) production of metalloproteinases (collagenase, gelatinase, stromelysin) and prostaglandin E2 (PGE2) in rabbit articular chondrocytes (RAC). Exposure of RAC to recombinant human platelet-derived growth factor homodimer BB (PDGF-BB; 2-200 ng/ml) in the presence of stimulatory and substimulatory concentrations of IL-1 alpha resulted in a marked augmentation of metalloproteinase and PGE2 production. PDGF-BB exerted no agonist effects on RAC responsiveness. PDGF-BB up-regulated the number of IL-1 receptors per chondrocyte but had no effect on receptor affinity. Cycloheximide and actinomycin D caused a concentration-dependent suppression of the PDGF-BB-mediated potentiation of radiolabeled IL-1 alpha binding to RAC and cell responsiveness to IL-1 alpha. Similarly, IL-1 increased the number of PDGF receptors on RAC without changing receptor affinity. These data are discussed within the context of cytokine-growth factor interactions as components of the pathogenesis of arthritic diseases.
Eco green flexible hybrid photovoltaic-thermoelectric solar cells with nanoimprint technology and roll-to-roll manufacturing (2010)

This paper explores the technical and commercial feasibility of nanotechnology based, high-efficiency, photovoltaic-thermoelectric hybrid solar cells as an environmentally-friendly, renewable energy source for residential and commercial buildings. To convert as much as possible of the usable photovoltaic (58% of the Energy Density) and thermoelectric (42% of the Energy Density) solar spectrum into electricity, a hybrid multilayer system is presented which comprises of 1) carbon nanotube (CNT) embedded in conducting polymers such as P3HT (poly(3-hexylthiophene) or P3OT (poly3-octylthiophene), 2) 3D gold nanostructures exhibiting plasmonic resonances for energy conversion, 3) nanoantenna architecture to capture IR energy, 4) a composite of Bi2Te3, SiGe nanocrystals and Au nanoshells as thermoelectric energy conversion layer, 5) configuration of the above items engineered in the form of meta-material designs that by virtue of their 3D structures ensure that incident light is neither reflected nor transmitted, but is rather all absorbed, 6) a multilayer arrangement of the above layers in a fractal architecture to capture all the wavelengths from 200 to 3000 nm<sup>8</sup> and the matching electronic interface for each layer. The roll-to-roll manufacturing method presented will enable economical large-scale production of solar panels. This potentially transformational technology has the ability to replace the Si solar cell technology by reducing costs from $0.18/KWh to $0.003/KWh while introducing a more environmentally-friendly manufacturing process.

On resource management in heterogeneous wireless access networks application to automated highway systems (2010)

This paper discusses a general solution to provide quality of service (QoS) in heterogeneous wireless networks. The mechanisms we mainly discuss in this paper is resource management in a WiMAX-WiFi heterogenous wireless network within the context of an automated highway system (AHS). We show how different mechanisms within each network can be combined in order to insure the required QoS.
A novel architecture design for VLSI implementation of an FIR decimation filter (2005)

A novel architecture design of a one stage FIR filter for decimation is described. It performs the decimation of a 1-bit code at 1024KHz of double integration Sigma Delta modulation output to PCM at 16KHz. This architecture is designed in such a way that it needs only a simple control structure suitable for VLSI implementation. We devised an algorithm for generating the coefficients of the filter with a minimum of required hardware. It does not require storing the coefficients in a ROM and continuously reading it to calculate the convolution. The accumulators needed to perform the direct convolution are arranged in a way that simplifies and minimizes the hardware required for the filter implementation. The filter response is Sinc <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> (f) which provides sufficient attenuation for modulation generated by means of double integration. The implementation of this filter requires the generation of the coefficients and the performance of the convolution. Three coefficients are needed with every input to obtain the output sequence. The major feature of this architecture is the use of an efficient algorithm to obtain the coefficients thereby reducing the area and power consumption. It is very suitable for VLSI implementation in CMOS technology.
A 1.2 MHz, 25 V to 100 V GaN-based resonant Dickson switched-capacitor converter with 1011 W/in3 (61.7 kW/L) power density (2015)

Switched-capacitor (SC) converters have generated interest in the research community due to the possibility of achieving high power densities at high voltage conversion ratios. This work proposes a resonant, 1-to-4 voltage conversion ratio Dickson SC converter. A single inductor is utilized to achieve zero current switching of all transistors, which allows for high switching frequency and high conversion efficiency. A split-phase control scheme is used in order to eliminate the current transients associated with the Dickson SC converter and the resultant power loss. Employing these techniques, a 25 V to 100 V Dickson SC converter prototype is implemented with GaN transistors. The converter achieves a switching frequency of 1.2 MHz and a peak efficiency of 92 %. The power stage of the converter is able to achieve a power density of a 1011 W/in <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> at 263 W.
A Heterocomplex Formed by the Calcium-binding Proteins MRP8 (S100A8) and MRP14 (S100A9) Binds Unsaturated Fatty Acids with High Affinity (1997)

We show that unsaturated fatty acids (FAs) bind reversibly and with high affinity to a heterocomplex of 34 kDa (FA-p34) formed by the non-covalent association of two calcium-binding proteins of the S100 family: MRP8 (S100A8) and MRP14 (S100A9). Fatty acid-competition studies on the [3H]oleic acid.FA-p34-complex show that oleic, alpha-linoleic, gamma-linolenic, and arachidonic acids have IC50 values of about 1 microM, whereas palmitic and stearic acids are poor competitors. The binding of arachidonic acid is saturable with a single class of binding site per FA-p34, and a dissociation constant (Kd) of 0.13 microM is calculated. The individual subunits MRP8 and MRP14 show no binding properties for fatty acids, whereas a p34 complex reconstituted in vitro by the recombinant molecules exhibits binding properties, suggesting that the fatty acid-binding site of FA-p34 is created through heterocomplex formation. Furthermore, we demonstrate that lowering free Ca2+ levels to 16 nM results in a loss of the fatty acid-binding capacity of purified FA-p34. In calcium-induced differentiating keratinocytes, the amounts of FA-p34 are increased in the particulate (2.0 +/- 0.5 pmol of [3H]oleic acid/mg protein) and in the cytosolic (4.5 +/- 0.6 pmol of [3H]oleic acid/mg protein) fractions, whereas no FA-p34 can be detected in non-differentiated cultured keratinocytes. In abnormally differentiated keratinocytes (psoriasis) and in human polymorphonuclear leukocytes, FA-p34 is highly expressed (31.35 +/- 1.6 and 349.8 +/- 17.9 pmol of [3H]oleic acid/mg protein, respectively), pointing toward a role for this heteromer in mediating effects of unsaturated fatty acids in a calcium-dependent way during cell differentiation and/or inflammation.
Solving the Convex Cost Integer Dual Network Flow Problem (2003)

In this paper 1 , we consider an integer convex optimization problem where the objective function is the sum of separable convex functions (that is, of the form ∑ (i,j)ϵQ F̄ ij (w ij ) + ∑ iϵP B̄ i (μ i )), the constraints are similar to those arising in the dual of a minimum cost flow problem (that is, of the form μ i − μ j ≤ w ij , (i,j)∈Q), with lower and upper bounds on variables. Letn= |P|,m= |Q| , andUbe the largest magnitude in the lower and upper bounds of variables. We call this problemthe convex cost integer dual network flow problem. In this paper, we describe several applications of the convex cost integer dual network flow problem arising in a dial-a-ride transit problem, inverse spanning tree problem, project management, and regression analysis. We develop network flow-based algorithms to solve the convex cost integer dual network flow problem. We show that using the Lagrangian relaxation technique, the convex cost integer dual network flow problem can be transformed into a convex cost primal network flow problem where each cost function is a piecewise linear convex function with integer slopes. Its special structure allows the convex cost primal network flow problem to be solved inO(nmlog(n 2 /m)log(nU)time. This time bound is the same time needed to solve the minimum cost flow problem using the cost-scaling algorithm, and is also is best available time bound to solve the convex cost integer dual network flow problem.
Henoch-Schönlein Purpura Nephritis (1999)

Henoch-Schonlein purpura (HSP) is a systemic vasculitic disorder first reported by Heberden in 1806. The association of purpura and joint pain was described by Schonlein in 1837, who termed it “peliosis rheumatica.” Henoch added a description of four children with skin lesions associated with
