Thermoelectric Properties of Nanocrystalline Silicon from a Scaled‐Up Synthesis Plant (2013)

The figure of merit zT was calculated wrong in Figure The correct calculation can be seen in Figure Also the maximum zT value is rather 0.30 at 700 C than 0.32 as mentioned in the abstract, introduction and Section 2.2. However, the wrong calculation doesnt affect the discussion nor the interpretation. Figure 1. Correct calculation of zT for a) Figure 4 and b) Figure 5e in the above manuscript.
Supervised domain adaptation for I-vector based speaker recognition (2014)

In this paper, we present a comprehensive study on supervised domain adaptation of PLDA based i-vector speaker recognition systems. After describing the system parameters subject to adaptation, we study the impact of their adaptation on recognition performance. Using the recently designed domain adaptation challenge, we observe that the adaptation of the PLDA parameters (i.e. across-class and within-class co variances) produces the largest gains. Nonetheless, length-normalization is also important; whereas using an indomani UBM and T matrix is not crucial. For the PLDA adaptation, we compare four approaches. Three of them are proposed in this work, and a fourth one was previously published. Overall, the four techniques are successful at leveraging varying amounts of labeled in-domain data and their performance is quite similar. However, our approaches are less involved, and two of them are applicable to a larger class of models (low-rank across-class).
Mobile IPv6 Route Optimisation for Network Mobility (MIRON) (2007)

The Network Mobility Basic Support protocol enables networks to roam
and attach to different access networks without disrupting the ongoing
sessions that nodes of the network may have. By extending the Mobile
IPv6 support to Mobile Routers, nodes of the network are not required
to support any kind of mobility, since packets must go through the
Mobile Router-Home Agent (MRHA) bi-directional tunnel. Communications
from/to a mobile network have to traverse the Home Agent, and
therefore better paths may be available. Additionally, this solution
adds packet overhead, due to the encapsulation. This document
describes an approach to the Route Optimisation for NEMO, called
Mobile IPv6 Route Optimisation for NEMO (MIRON). MIRON enables
mobility-agnostic nodes within the mobile network to directly
communicate (i.e. without traversing the MRHA bi-directional tunnel)
with Correspondent Nodes. The solution is based on the Mobile Router
performing the Mobile IPv6 Route Optimisation signalling on behalf of
the nodes of the mobile network. This document (in an appendix) also
analyses how MIRON fits each of the NEMO RO Aeronautics requirements.
Distributed Mining of Spatial High Utility Itemsets in Very Large Spatiotemporal Databases using Spark In-Memory Computing Architecture (2020)

Finding Spatial High Utility Itemsets (SHUIs) in a spatiotemporal database is a challenging problem of great importance in many real-world applications. Most previous works focused on the sequential discovery of SHUIs in a database running on a single machine. Consequently, these works are not suitable for big data (or cloud-based) applications as they suffer from the scalability and fault tolerant problems. This paper proposes several novel pruning techniques to reduce the search space and present a more flexible distributed algorithm to find all desired itemsets from the database using Spark in-memory computing architecture. Our algorithm inherits several advantages of Spark, including low communication cost, fault tolerance, and high scalability. Experimental results demonstrate that the proposed algorithm has good scalability and performance on very large databases. Finally, we present a real-world navigation application in which SHUIs generated from the traffic congestion data have been employed to recommend alternative routes to the users.
Multi-zone shell and tube heat exchanger (2023)

A shell and tube heat exchanger has elongated shell having first and second opposing ends and an open interior. A core divides the open interior of the shell into first and second enclosed portions. The shell has first and second tube fluid openings at opposing ends. End plates divide the first and second enclosed portions into manifold portions and enclosed shell chamber portions. Tubes extend from the end plates, through the enclosed shell chambers to the core. Shell fluid openings are at sides of the elongated shell, a first fluid opening communicating with the first shell chamber, and a second fluid opening communicating with the second shell chamber. The shell has a long axis, and the end plates are angled relative to the long axis. The tubes are polygonal with rounded corners and straight sides. The heat exchanger can be used for both evaporation and condensation processes.
A Communication-Theory Based View on Telemedical Communication (2003)

Communication theory based analysis sheds new light on the use of health telematics. This analysis of structures in electronic medical communication shows communicative structures with special features. Current and evolving telemedical applications are analyzed. The methodology of communicational theory (focusing on linguistic pragmatics) is used to compare it with its conventional counterpart. The semiotic model, the roles of partners, the respective message and their relation are discussed. Channels, sender, addressee, and other structural roles are analyzed for different types of electronic medical communication. The communicative processes are shown as mutual, rational action towards a common goal. The types of communication/texts are analyzed in general. Furthermore the basic communicative structures of medical education via internet are presented with their special features. The analysis shows that electronic medical communication has special features compared to everyday communication: A third participant role often is involved: the patient. Messages often are addressed to an unspecified partner or to an unspecified partner within a group. Addressing in this case is (at least partially) role-based. Communication and message often directly (rather than indirectly) influence actions of the participants. Communication often is heavily regulated including legal implications like liability, and more. The conclusion from the analysis is that the development of telemedical applications so far did not sufficiently take communicative structures into consideration. Based on these results recommendations for future developments of telemedical applications/services are given.
GPU Accelerated Planning and Placement of Edge Clouds (2019)

Future 5G communication will rely on edge computing to meet diverse Quality of Service Requirements, in particular, end-to-end latency in the order of milliseconds. Placing edge clouds requires solving a large-scale set cover problem. We show how the challenge posed by the size of the problem can be overcome through GPU accelerated Natural Evolutional Strategies (NES). We present a system that allows the evaluation of technology choices, latency requirements and locations that should be covered at the example of the United States.
Metabolic Engineering of Microorganisms for the Production of Flavonoids (2020)

Flavonoids are a class of secondary metabolites found in plant and fungus. They have been widely used in food, pharmaceutical, and nutraceutical industries owing to their significant biological activities, such as antiaging, antioxidant, anti-inflammatory, and anticancer. However, the traditional approaches for the production of flavonoids including chemical synthesis and plant extraction involved hazardous materials and complicated processes and also suffered from low product titer and yield. Microbial synthesis of flavonoids from renewable biomass such as glucose and xylose has been considered as a sustainable and environmentally friendly method for large-scale production of flavonoids. Recently, construction of microbial cell factories for efficient biosynthesis of flavonoids has gained much attention. In this article, we summarize the recent advances in microbial synthesis of flavonoids including flavanones, flavones, isoflavones, flavonols, flavanols, and anthocyanins. We put emphasis on developing pathway construction and optimization strategies to biosynthesize flavonoids and to improve their titer and yield. Then, we discuss the current challenges and future perspectives on successful strain development for large-scale production of flavonoids in an industrial level.

Private Membership Test for Bloom Filters (2015)

We study the problem of running a set membership test in private manner. We require that a client wants to have the option of not revealing the item for which the membership test is done. Respectively, the server does not wants to reveal the contents of the whole set. A Bloom filter is applied in the membership test. We present two protocols based on prior work as well as a new protocol. Each of these is having a slightly different privacy and complexity properties. We motivate the problem in the context of an anti-malware client checking application fingerprints against a cloud-based malware signature database.
Peritoneal Dialysis Today (2003)

Peritoneal dialysis (PD) is an invaluable tool in the treatment of patients with end-stage renal disease, which does not preclude a renal transplant, but incurs lower costs than other treatment options and represents an alternative when the vascular access is not feasible. Moreover, PD can be integrated in the armamentarium of different therapies a
A Wideband Filtering Antenna Array With Harmonic Suppression (2020)

In this article, a wideband 2 × 2 filtering antenna array is proposed and studied for fixed beam applications. The device is composed of a patch antenna array, and a slotline-based four-way filtering power divider has served as the feeding network. The integration of the antenna and the feeding parts is not a simple combination but a cosynthesis, where the characters of the two parts are both involved during the integration. First, the presented network is analyzed through an equivalent-circuit study to verify the frequency selectivity. Subsequently, integration synthesis of the network and the patch array is carried out to realize the filtering antenna array. For demonstration purposes, a filtering antenna array centered at 3 GHz is developed and fabricated. The measured absolute impedance bandwidth is 1.13 GHz, corresponding to a fractional bandwidth of 37.1%, and out-of-band rejection of up to 9.5 GHz is achieved. Compared with the array fed by a traditionally T-junction-based power divider, the absolute impedance bandwidth of the filtering array is significantly increased by 47%. The in-band gain of the proposed array is higher than 9.7 dBi, which is over 12.1 dBi from 2.75 to 3.25 GHz. The results denote that compared with the previously reported literature, the proposed filtering antenna array features sharp cutoff response, wide impedance bandwidth, high gain, and low cross-polarization level, with the harmonic suppression of up to three times the center frequency.
Discontinuous Molecular Films Can Control Metal/Semiconductor Junctions (2004)

Molecular control over charge transport across a metal/semiconductor interface persists even if there is only a partial monolayer of polar molecules at the interface. This is because the long-range electrostatic effect of the dipole layer also affects the semiconductor regions under the film's pinholes. Thus, all types of polar molecules that show average order at the interface can be used.
A Multicenter Study of Preventable Contact Burns From Glass Fronted Gas Fireplaces (2015)

Glass fronted gas fireplaces (GFGFs) have exterior surfaces that can reach extremely high temperatures. Burn injuries from contact with the glass front can be severe with long-term sequelae. The Consumer Product Safety Commission reported that these injuries are uncommon, whereas single-center studies indicate a much higher frequency. The purpose of this multi-institutional study was to determine the magnitude and severity of GFGF injuries in North America. Seventeen burn centers elected to participate in this retrospective chart review. Chart review identified 402 children ≤10 years of age who sustained contact burns from contact with GFGF, who were seen or admitted to the study hospitals from January 2006 to December 2010. Demographic, burn, treatment, and financial data were collected. The mean age of the study group was 16.8 ± 13.3 months. The majority suffered burns to their hands (396, 98.5%), with burns to the face being the second, much less common site (14, 3.5%). Two hundred and sixty-nine required rehabilitation therapy (66.9%). The number of GFGF injuries reported was 20 times greater than the approximately 30 injuries estimated by the Consumer Product Safety Commission's 10-year review. For the affected children, these injuries are painful, often costly and occasionally can lead to long-term sequelae. Given that less than a quarter of burn centers contributed data, the injury numbers reported herein support a need for broader safety guidelines for gas fireplaces in order to have a significant impact on future injuries.
Evidence for rearrangement, amplification, and expression of c-myc (2016)

Amplifiled cellular genes are frequently man- ifested in one of two cytologically recognizable forms, double minutes or homogeneously staining regions. Additionally, evidence is accumulating that aberrant expression of cellular genes (including oncogenes) may be mediated by gene ampli- fication. We now describe the amplification and expression of the cellular oncogene c-myc in double-minute-containing cells from a patient with glioblastoma multiforme, and we have shown that the amplification is associated with rearrangement of the c-myc gene. This finding further supports the common association of the myc gene family in neurogenic tumors and provides evidence of myc gene amplification in human brain
A two‐phase model of plantar tissue: a step toward prediction of diabetic foot ulceration (2014)

A new computational model, based on the thermodynamically constrained averaging theory, has been recently proposed to predict tumor initiation and proliferation. A similar mathematical approach is proposed here as an aid in diabetic ulcer prevention. The common aspects at the continuum level are the macroscopic balance equations governing the flow of the fluid phase, diffusion of chemical species, tissue mechanics, and some of the constitutive equations. The soft plantar tissue is modeled as a two-phase system: a solid phase consisting of the tissue cells and their extracellular matrix, and a fluid one (interstitial fluid and dissolved chemical species). The solid phase may become necrotic depending on the stress level and on the oxygen availability in the tissue. Actually, in diabetic patients, peripheral vascular disease impacts tissue necrosis; this is considered in the model via the introduction of an effective diffusion coefficient that governs transport of nutrients within the microvasculature. The governing equations of the mathematical model are discretized in space by the finite element method and in time domain using the θ-Wilson Method. While the full mathematical model is developed in this paper, the example is limited to the simulation of several gait cycles of a healthy foot.
Robust H-infinity Output Feedback Control for Nonlinear Systems (1994)

The study of robust nonlinear control has attracted increasing interest over the last few years. Progress has been aided by the recent extension of the linear quadratic results which links the theories of L2 gain control (nonlinear H∞ control), differential games, and stochastic risk sensitive control. In fact, significant advances in both linear and nonlinear H∞ theory have drawn upon results from the theories of differential games and stochastic risk sensitive control. Despite these advances in H∞ control theory, practical controllers for complex nonlinear systems which operate on basic H∞ principles have not been realized to date. Issues of importance to the design of a practical controller include (i) computational complexity, (ii) operation solely with observable quantities, and (iii) implementability in finite time. In this dissertation we offer a design procedure which yields, practical and implementable H∞ controllers and meets the, mandate of the above issues for general nonlinear systems. In particular, we develop a well defined and realistically implementable procedure for designing robust output feedback controllers for a large class of nonlinear systems. We analyze this problem in both continuous time and discrete time settings. The robust output feedback control problem is formulated as a dynamic game problem. The solution to the game is obtained by transforming the problem into an equivalent full state feedback problem where the new state is called the information state. The information state method provides a separated control policy which involves the solution of a forward and a backward dynamic programming equation. Obtained from the forward equation is the information state, and from the backward equation is the value function of the game and the optimal information state control. The computer implementation of the information state controller is addressed and several approximations are introduced. The approximations are designed to decrease the online computational complexity of controller.
CD44-Epidermal Growth Factor Receptor Interaction Mediates Hyaluronic Acid-promoted Cell Motility by Activating Protein Kinase C Signaling Involving Akt, Rac1, Phox, Reactive Oxygen Species, Focal Adhesion Kinase, and MMP-2 (2008)

Hyaluronic acid (HA) is known to play an important role in motility of tumor cells. However, the molecular mechanisms associated with HA-promoted melanoma cell motility are not fully understood. Treatment of cells with HA was shown to increase the production of reactive oxygen species (ROS) in a CD44-dependent manner. Antioxidants, such as N-acetyl-l-cysteine and seleno-l-methionine, prevented HA from enhancing cell motility. Protein kinase C (PKC)-alpha and PKCdelta were responsible for increased Rac1 activity, production of ROS, and mediated HA-promoted cell motility. HA increased Rac1 activity via CD44, PKCalpha, and PKCdelta. Transfection with dominant negative and constitutive active Rac1 mutants demonstrated that Rac1 was responsible for the increased production of ROS and cell motility by HA. Inhibition of NADPH oxidase by diphenylene iodonium and down-regulation of p47Phox and p67Phox decreased the ROS level, suggesting that NADPH oxidase is the main source of ROS production. Rac1 increased phosphorylation of FAK. FAK functions downstream of and is necessary for HA-promoted cell motility. Secretion and expression of MMP-2 were increased by treatment with HA via the action of PKCalpha, PKCdelta, and Rac1 and the production of ROS and FAK. Ilomastat, an inhibitor of MMP-2, exerted a negative effect on HA-promoted cell motility. HA increased interaction between CD44 and epidermal growth factor receptor (EGFR). AG1478, an inhibitor of EGFR, decreased phosphorylation of PKCalpha, PKCdelta, and Rac1 activity and suppressed induction of p47Phox and p67Phox. These results suggest that CD44-EGFR interaction is necessary for HA-promoted cell motility by regulating PKC signaling. EGFR-Akt interaction promoted by HA was responsible for the increased production of ROS and HA-promoted cell motility. In summary, HA promotes CD44-EGFR interaction, which in turn activates PKC signaling, involving Akt, Rac1, Phox, and the production of ROS, FAK, and MMP-2, to enhance melanoma cell motility.
SU-E-T-553: Measurement of Incident Electron Spots On TrueBeam (2013)

Purpose: Lateral dimensions of the incident electron beam (spot sizes) are essential for accurate modelling of x-ray fields, especially for small field output factors and penumbrae. We present spot sizes measured on the Varian TrueBeam linac and propose an explanation for the observed shapes. Methods: Spot were measured on 3 TrueBeam linacs using the 4X, 6X, 6FFF, 8X, 10X, 10FFF, and 15X beams. Two methods were used: a spot camera, and an edge CT reconstruction based on images of a thin plate with edge intersecting the beam at different collimator rotations. 2-dimensional Gaussian functions were fit to the data, with the spot orientation used as a fitting parameter. Results: Spots were consistent for the 3 linacs. Sigmas of the fitted Gaussians were between 0.47 and 1.05 mm for all the beams. The 6X, 6FFF, and 15X beams had a distinct shape: the major axes were 30–40% larger than the minor axes, and the major axes were oriented 40 degrees from the inplane direction. The remaining spots were more symmetric, with major axes at most 15% larger than minor, and a similar orientation. The spot shapes could be explained by positing a helical electron motion at the entrance to the bend magnet, and using the known (non-achromatic) transport through the magnet. Fringe fields of the bend magnet, solenoid, or steering coils could produce the helical motion; the precise source is not known. Spots measured with the edge technique were 10% smaller in size than those measured with the camera. The 10FFF spots were 10% smaller than the 10X spots, as measured with the camera, but the 6X and 6FFF spots were similar to each other. Conclusion: Representative spots for TrueBeam are presented. Values may be used for input to modelling of fluence output, for example using Monte Carlo methods. Several of the authors are employees of Varian Medical Systems, as noted in the affiliations.
Reduced Graphene Oxide - Molybdenum Disulfide Aerogel Nanocomposite Electrodes for Supercapacitors (2018)

Supercapacitors have attracted extensive attention for their high specific power and moderate energy densities. Nanoscale structure and high surface area are the two main requirements for a supercapacitor electrode with high performance. We report on the fabrication and electrochemical characterization of hybrid aerogel nanocomposite supercapacitor electrodes composed of reduced graphene oxide and molybdenum disulfide nanosheets on nickel foams. Graphene oxide was produced using Tour Method. Reduced graphene oxide (rGO) aerogel was produced from graphene oxide dispersion via solvothermal technique followed by freeze-drying and thermal reduction. For the fabrication of hybrid electrodes, produced rGO aerogels were simply pressed onto nickel foams, which was followed by drop-casting of exfoliated molybdenum disulfide (MoS2) nanosheets onto the rGO aerogel. Electrochemical properties such as specific capacity and capacity retention of the fabricated nanocomposite electrodes were examined through cyclic voltammetry, chronopotentiometry and electrochemical impedance spectroscopy in two electrode configuration. Results of the measurements were compared to that of control samples fabricated simply by pressing bare rGO aerogel and bare MoS2 nanosheets directly onto nickel foams. In order to determine the effect of electrolyte type on the electrochemical properties of the hybrid nanocomposite electrodes, various environmentally friendly and neutral aqueous solutions, such as lithium sulfate (Li2SO4), sodium sulfate (Na2SO4), sodium chloride (NaCl) and potassium chloride (KCl) were investigated as the electrolytes. Fabricated hybrid supercapacitor electrodes showed encouraging results with a specific capacitance of 38.69 mF/cm2 and a Coulombic efficiency of 83%. Following 1000 charge/discharge cycles, specific capacitance of the fabricated electrodes degraded to 94% of its initial capacitance value. A comprehensive analysis on the electrochemical properties of the fabricated supercapacitor will be presented
