Probabilistic Center Voting Method For Subsequent Object Tracking And Segmentation (2009)

In this paper, we introduce a novel algorithm for object tracking in video sequence. In order to represent the object to be tracked, we propose a spatial color histogram model which encodes both the color distribution and spatial information. The object tracking from frame to frame is accomplished via center voting and back projection method. The center voting method has every pixel in the new frame to cast a vote on whereabouts the object center is. The back projection method segments the object from the background. The segmented foreground provides information on object size and orientation, omitting the need to estimate them separately. We do not put any assumption on camera motion; the proposed algorithm works equally well for object tracking in both static and moving camera videos.
Prediction of F0 contours from symbolic and numerical variables using continuous conditional random fields (2012)

Regression of continuous-valued variables as a function of both categorical and continuous predictors arises in some areas of speech processing, such as when predicting prosodic targets in a text-to-speech system. In this work we investigate the use of Continuous Conditional Random Fields (CCRF) to conditionally predict F0 targets from a series of s symbolic and numerical predictive features derived from text. We derive the training equations for the model using a Least-Squares-Error criterion within a supervised framework, and evaluate the proposed system using this objective criterion against other baseline models that can handle mixed inputs, such as regression trees and ensemble of regression trees.
A New Methodological Approach to the Characterization of Optimal Charging Rates at the Hydrogen Plasma Smelting Reduction Process Part 1: Method (2022)

The development of a carbon lean steel production process following the concept of direct carbon avoidance is one of the most challenging tasks the iron and steel industry must tackle in just a few decades. The necessary drastic reduction of 80% of the process's inherent emissions by 2050 is only possible if a new process concept that uses hydrogen as the primary reductant is developed. The Hydrogen Plasma Smelting Reduction (HPSR) of ultra-fine iron ores is one of those promising concepts. The principle was already proven at a lab scale. The erection of a bench-scale facility followed this, and further scaled-ups are already planned for the upcoming years. For this scale-up, a better understanding of the fundamentals of the process is needed. In particular, knowledge of the kinetics of the process is essential for future economically feasible operations. This investigation shows the principles for evaluating and comparing the process kinetics under varying test setups by defining a representative kinetic parameter. Aside from the fundamentals for this definition, the conducted trials for the first evaluation are shown and explained. Several differences in the reduction behavior of the material at varying parameters of the process have already be shown. However, this investigation focuses on the description and definition of the method. An overall series of trials for detailed investigations will be conducted as a follow-up.
AN APPROACH TO SHAFTING STABILITY AT THE VERGE OF OFF-STABILIZATION FOR 300 MW TURBO-GENERATOR SET MADE IN HOME (2008)

Through analysis of shafting stability for a 300 MW turbo-generator set made in home, and working condition of its bearings und different loads, as well as through calculation and comparison of unit’s revolution speed under off-stabilization, the changing relationship between shafting stability and critical speed of each rotor has been analysed. Results show that the shafting stability can be ensured only when the influence of external factors has to be isolated, and especially for shafting at the verge of off-stabilization.
Next-Generation Environment-Aware Cellular Networks: Modern Green Techniques and Implementation Challenges (2016)

Over the last decade, mobile communications have been witnessing a noteworthy increase of data traffic demand that is causing an enormous energy consumption in cellular networks. The reduction of their fossil fuel consumption in addition to the huge energy bills paid by mobile operators is considered as the most important challenges for the next-generation cellular networks. Although most of the proposed studies were focusing on individual physical layer power optimizations, there is a growing necessity to meet the green objective of fifth-generation cellular networks while respecting the user's quality of service. This paper investigates four important techniques that could be exploited separately or together in order to enable wireless operators achieve significant economic benefits and environmental savings: 1) the base station sleeping strategy; 2) the optimized energy procurement from the smart grid; 3) the base station energy sharing; and 4) the green networking collaboration between competitive mobile operators. The presented simulation results measure the gain that could be obtained using these techniques compared with that of traditional scenarios. Finally, this paper discusses the issues and challenges related to the implementations of these techniques in real environments.
Acquired Von Willebrand Disease in Patients with Waldenström Macroglobulinemia (2017)

Abstract Introduction: Acquired von Willebrand disease (VWD) is uncommonly observed in patients with Waldenstrom Macroglobulinemia (WM), and necessitates treatment intervention. The clinical characteristics for WM patients with acquired VWD, as well as outcomes following therapy have not been well characterized. Methods: We carried a retrospective study in patients with new diagnosed diagnosed WM who were evaluated at our institution, and tested for the presence of VWD. The presence of any VWD was evaluated by measuring levels of VW factor antigen (VWFAG), VW factor activity (VWFACT) and factor VIII (FVIII). Low-level VWD was diagnosed if VWFAG, VWFACT and FVIII levels were between 30% and 50%. VWD was diagnosed if VFWAG, VWFACT and FVIII were Results: A total of 320 patients with WM were tested for VWD, of whom 271 (85%) showed no evidence of deficiency, and 49 (15%) showed any VWD. Patients were tested because they provided a history of easy bruising or bleeding. Thirty patients had low-level VWD (61%) and 19 were VWD (39%). The median IgM level of patients with any VWD was 5,660 mg/dl (range 1,800-10,300 mg/dl) and 2270 mg/dl (95% CI 25-11,000 mg/dl) in patients without VWD. Patients with any VWD were more likely to have IgM levels 3,000-5,999 mg/dl and 6,000+ mg/dl (47% vs. 31%, and 45% vs. 6%, respectively; p 6 K/uL (29% vs. 50%; p=0.006) than patients without VWD. There were no differences in age, sex, hemoglobin levels, platelet count and bone marrow involvement between WM patients with any and without VWD. In the multivariate regression analyses, patients with IgM levels 3,000-5,999 mg/dl and 6,000+ mg/dl had OR 11.1 (95% CI 3.7-33.3; p Conclusion: Patients with WM can present with acquired VWD, which seems to strongly correlate with high serum IgM levels. VWD improves and in most cases resolves with response to WM therapy. The depth of response to therapy correlates with the degree of improvement in VWD.

Terahertz waveguide signal processing: passive and active devices (2019)

Based on parallel-plate waveguides (PWWGs), we have developed both passive and active terahertz (THz) sensors, filters, splitters, and switches. We utilize the PPWG since it has excellent waveguiding properties with a simple geometry that allows for incorporation of unique electromagnetic functionalities. A few passive devices are discussed while the focus remains on active devices. The active control is enabled by our innovation to incorporate liquid metals, which can be relocated by application of a small electrical voltage (&lt; 4V), as part of the waveguide geometry itself. The device geometry directly affects the device performance (e.g., frequency band of operation, channel output power). Therefore, by moving the liquid metal, the geometry is reconfigured which results in altering the device function. To show the practicality of these devices to be used for THz wireless communications, we demonstrate the ability of these devices to support a 1 Gb/s data stream on a THz carrier wave and show that this signal can be successfully switched with high modulation depths of &plusmn;40 dB. These results show the strong promise of these components to form important signal processing building blocks in the future infrastructure of THz wireless communications.
A balanced CMOS OpAmp with high EMI immunity (2014)

In this paper a balanced CMOS operational amplifier which has higher electromagnetic interference (EMI) immunity compared to a double differential amplifier and standard Miller operational amplifier, has been introduced. The proposed amplifier has better EMI immunity, from 1 MHz - 1 GHz, by keeping specifications such as gain, -3 dB bandwidth, phase margin, power supply rejection and unity gain frequency same as in the Miller operational amplifier. Analysis and simulation results are compared when an EMI signal of 1.1 Vpp applied at the input terminal. The simulation results show that the EMI-induced offset voltage is lesser over a wide range of frequencies for the proposed amplifier.
Molecular Characterization of Cytosolic Phospholipase A2-β (1999)

We have isolated a cDNA encoding a 1012-amino acid polypeptide cPLA2-beta, that has significant homology with cPLA2-alpha in both the calcium-dependent lipid binding domain as well as in the catalytic domain. Transient expression of cPLA2-beta cDNA in COS cells results in an increase in calcium-dependent phospholipase A1 (PLA1) and PLA2 activities compared with vector-transfected cells. cPLA2-beta is markedly less selective for cleavage at sn-2 as compared with cPLA2-alpha and cPLA2-gamma. Northern analysis reveals a cPLA2-beta transcript of 8 kilobase pairs that is expressed in all the human tissues examined. With the identification of cPLA2-beta, the newly defined cPLA2 family now comprises three members that may have dramatically different mechanisms for regulation of expression and enzymatic activation.

The performance of a DC to 3 GHz externally modulated link utilising balanced high-power photodetectors is presented. High power photodiodes with 1 dB compression currents in excess of 56 mA are used with a 240 mW NdYAG laser, a dual-output 4 V Vπ modulator, and balanced 100 mA total photocurrent yielding a link gain of 3 to 6 dB and a noise figure of 15.5 – 17.5 dB.
THE KINETICS OF ZINC, COBALT AND NICKEL EXTRACTION IN THE D2EHPA-HEPTANE-HC104 SYSTEM USING THE ROTATING DIFFUSION CELL TECHNIQUE (1989)

ABSTRACT The kinetics of the extraction of zinc, cobalt and nickel from perchlorate solutions using di 2-ethyl-hexyl phosphoric acid (D2EHPA) dissolved in heptane were studied using the Rotating Diffusion Cell technique. The extraction of each metal was investigated individually over a wide range of metal concentration, extractant concentration, pH and temperature conditions. The data were analysed in terms of a mass transfer with chemical reaction (MTWCR) mechanism. Hughes and Rod'/s generalized MTWCR model was used to fit the cobalt data using kinetic and equilibrium parameters. The zinc and nickel data were quantitatively described within the framework of the MTWCR model. The zinc extraction rate was so fast that mass transfer alone was rate controlling. The nickel extraction experiments were so slow that the metal-ligand complex formation was incomplete in the aqueous film. Some reaction was determined to be occurring in the aqueous bulk solution as well.
Thinking about visual programs (1996)

The theme of this paper is that simple comparisons between diagrams and text are inappropriate, at least in the programming area. Simple text-graphic comparisons are certainly very popular among computer scientists; we surveyed the literature and found that the vast majority made the simple assertion that visual programming would be better. Various reasons were cited; we present some of them.
Impact of a Single Intracoronary Administration of Adiponectin on Myocardial Ischemia/Reperfusion Injury in a Pig Model (2010)

These data suggest that adiponectin protects against I/R injury in a preclinical pig model through its ability to suppress inflammation, apoptosis, and oxidative stress. Administration of intracoronary adiponectin could be a useful adjunctive therapy for acute myocardial infarction.

Correlation Between Penile Angiography and Duplex Scanning of Cavernous Arteries in Impotent Men (1990)

During the diagnostic evaluation of patients with vasculogenic impotence duplex scanning has been proposed as a reliable noninvasive method to evaluate the cavernous arteries. However, the sensitivity and specificity of this test have never been elucidated. To provide insight into the clinical value of this test 25 men who presented with impotence and failed to respond to 60 mg. intracavernous papaverine were evaluated with duplex scanning and the results of this modality were compared to penile angiography. The cavernous arteries were considered normal by duplex scanning if the artery demonstrated either a 60% or greater increase in diameter and/or a peak flow velocity of greater than 25 cm. per second 5 minutes after papaverine injection. Penile angiography was considered normal if both cavernous arteries were visualized and appeared to be normal radiographically (after intracorporeal papaverine). In the 25 patients studied there was no significant difference in peak flow velocity between patients with normal or abnormal cavernous arteries by angiography. In addition, arterial dilatation (more than 60%) after papaverine injection did not correlate with the results of the angiogram. These data demonstrate that duplex scanning of the cavernous arteries does not correlate well with what is observed by penile angiography in a selected population of men with vasculogenic erectile dysfunction. Since penile angiography itself has limitations in the evaluation of the penile arteries, the reliability of duplex scanning to identify cavernous artery dysfunction needs additional confirmation.
A Novel Iterative Detection Scheme of Bootstrap Signals for ATSC 3.0 System (2018)

This paper derives a maximum-likelihood decision rule to detect the signaling information conveyed by the bootstrap for an ATSC 3.0 system and proposes an iterative detection scheme to improve the detection performance. The proposed detection scheme iteratively averages the channel estimates for two consecutive bootstrap symbols by exploiting the previously detected symbol. The simulation results show that the proposed detection scheme can obtain a signal-to-noise ratio gain of approximately 2.0 dB at a frame error rate of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> compared to the conventional detection scheme. Furthermore, this paper analyzes the computational complexity of the proposed detection scheme and presents the number of iterations sufficient to provide a good performance-complexity trade-off.
Optimal Information Control in Cyber-Physical Systems (2016)

In this paper, we address optimal information control in cyber-physical systems. In particular, we study the optimal closed-loop policy for transmission of measurements of a stochastic dynamical system through a communication channel given estimation and communication costs. We develop a framework for optimizing an aggregate cost function that incorporates the estimation and the communication costs over a finite time horizon. We obtain the optimal closed-loop policy, and show that it can be expressed directly in terms of the value of information. In addition, we propose an approximation algorithm that yields a suboptimal closed-loop policy. Numerical and simulation results are presented for a simple system.
Would Diamond Nanorods Be Stronger than Fullerene Nanotubes? (2003)

On the basis of literature ab initio data, we show that diamond nanorods would have a brittle fracture force and a zero strain stiffness that exceeds carbon nanotubes for radii greater than about 1−3 nm, depending on the orientation of the diamond nanorod. The energetic stability of diamond nanorods is predicted by molecular modeling to be comparable to single-walled carbon nanotubes. It is concluded that diamond nanorods represent an important and viable target structure for synthesis.
Mobility-Enhanced CMOS Technologies Using Strained Si/SiGe/Ge Channels (2006)

It has been well recognized that continuous increase in drive current is mandatory for successive growth of future CMOS LSIs. This means that the mobility enhancement has to keep being pursued in each technology node. For this purpose, a variety of local strain and global strain techniques have recently been developed and some of them have already been implemented in real products as presented in T. Ghani et al. (2003). This paper reports our recent approaches on the development of mobility-enhanced device structures based on the global strain substrates
High-power magnetron RF source for superconducting Linacs of ADS and intensity-frontier projects. (2013)

A high-power magnetron RF source with a rapid control in phase and power based on injection-locked CW magnetrons is proposed to drive individually Superconducting RF (SRF) cavities with an energy gain of ≈20 MeV/m for proton or ion GeV-scale linacs of the Accelerator Driven Systems (ADS) or other intensity frontier projects. The RF power up to few hundreds kW is required for the SRF cavity accelerating an average beam current of 10 mA or more. Experimental tests performed with 1 kW magnetrons operating in injection-locked mode indicate the potential capability of the proposed RF source to power the SRF cavities with instability of the accelerating field phase and amplitude of less than 1 degree and 1%, respectively, utilizing a phase control. The controlled RF source will suppress parasitic modulation of the accelerating field in the SRF cavities caused by mechanical oscillations, perturbations resulting from beam loading, dynamic detuning, ripples resulted from the power supplies of the magnetrons, etc. Utilization of the magnetron RF sources will significantly reduce capital cost of the superconducting linacs over the traditional RF sources as klystrons, IOTs and solid-state amplifiers. Results of the performed experimental tests and the evaluations are analysed and discussed in this report.
TIM-3 Suppresses Anti-CD3/CD28-Induced TCR Activation and IL-2 Expression through the NFAT Signaling Pathway (2015)

TIM-3 (T cell immunoglobulin and mucin-domain containing protein 3) is a member of the TIM family of proteins that is preferentially expressed on Th1 polarized CD4+ and CD8+ T cells. Recent studies indicate that TIM-3 serves as a negative regulator of T cell function (i.e. T cell dependent immune responses, proliferation, tolerance, and exhaustion). Despite having no recognizable inhibitory signaling motifs, the intracellular tail of TIM-3 is apparently indispensable for function. Specifically, the conserved residues Y265/Y272 and surrounding amino acids appear to be critical for function. Mechanistically, several studies suggest that TIM-3 can associate with interleukin inducible T cell kinase (ITK), the Src kinases Fyn and Lck, and the p85 phosphatidylinositol 3-kinase (PI3K) adaptor protein to positively or negatively regulate IL-2 production via NF-κB/NFAT signaling pathways. To begin to address this discrepancy, we examined the effect of TIM-3 in two model systems. First, we generated several Jurkat T cell lines stably expressing human TIM-3 or murine CD28-ECD/human TIM-3 intracellular tail chimeras and examined the effects that TIM-3 exerts on T cell Receptor (TCR)-mediated activation, cytokine secretion, promoter activity, and protein kinase association. In this model, our results demonstrate that TIM-3 inhibits several TCR-mediated phenotypes: i) NF-kB/NFAT activation, ii) CD69 expression, and iii) suppression of IL-2 secretion. To confirm our Jurkat cell observations we developed a primary human CD8+ cell system that expresses endogenous levels of TIM-3. Upon TCR ligation, we observed the loss of NFAT reporter activity and IL-2 secretion, and identified the association of Src kinase Lck, and PLC-γ with TIM-3. Taken together, our results support the conclusion that TIM-3 is a negative regulator of TCR-function by attenuating activation signals mediated by CD3/CD28 co-stimulation.
