Differential equation based impedance measurement for series-compensated lines (2003)

Differential equation based digital algorithms for measurement of a fault loop impedance are studied in relation to their application for protective relaying of single and parallel series-compensated lines. Adaptation of the impedance measurement algorithms to the specific nature of transients in the relaying signals for the series-compensated lines is presented. Correct measure of the distance to a fault is provided by incorporating the representation of the series-capacitor equipped with metal-oxide varistor into the fault loop models. The algorithms were investigated for a variety of fault conditions using ATP-EMTP.
Lies and Medicine (1992)

Through the centuries physicians have come to expect honest, self disclosures from patients who seek help for their ailments. For the most part this is still true, but occasionally the physician will doubt a given history, find inconsistencies and struggle with personal discomfort that the story is suspicious and the patient is lying. Blatant motives for lying may be monetary compensation, work or school days offer sympathy at home. Each situation will be a judgement call on the physician's part: reassure medically and dismiss, nurturant confrontation, then question further to understand, or participate in the manipulation by signing a medical slip. These are practical options. Each family physician must treat according to his or her educated clinical assessment of the moment, rather than on a Supreme Court Judgement
of the truth! Greater knowledge about truth and lies in general is
userful in every aspect of life, our own and ow patients'.

Real-Time Stroke Textures (2001)

Shading in line drawings is expressed by varying the stroke width or density of strokes covering an object’s surface. In their pioneering work, Winkenbach and Salesin introduced the concept of “prioritized stroke textures ” to the emerging field of non-photorealistic rendering. 1 Despite the advances in processing power in the years since then, the sheer number of lines to draw prevents this method from running in real time. A real-time approach for hatching was presented by Lake et al, 2 which chooses from a set of textures based on the brightness at vertices, subdividing polygons if necessary. However, the method is very CPU-heavy and requires many polygons. Our new technique uses per-pixel shading graphics hardware to implement non-photorealistic shading. The texture-combining facilities accessible via OpenGL on NVIDIA GeForce and ATI Radeon cards provide the flexibility necessary to vary the line width or number of strokes per area. To indicate shading by variable-width hatching, a 3D halftone pattern is created as texture T and compared at every pixel with the target intensity I, creating black or white pixels. 3 Halftoning, however, yields unsatisfying results for interactive applications because of the computer screen’s limited resolution. To smooth the harsh transition from white to black we instead take the inverted sum of T and I and scale it by some constant c&gt; 1. After clamping the result to the range (0…1)we get a mostly black and white output while still preserving a few gray levels (see Figure 1). Figure 1. Lighting-dependend stroke width.

CAVVA: Computational Affective Video-in-Video Advertising (2013)

Advertising is ubiquitous in the online community and more so in the ever-growing and popular online video delivery websites (e.g., YouTube). Video advertising is becoming increasingly popular on these websites. In addition to the existing pre-roll/post-roll advertising and contextual advertising, this paper proposes an in-stream video advertising strategy-Computational Affective Video-in-Video Advertising (CAVVA). Humans being emotional creatures are driven by emotions as well as rational thought. We believe that emotions play a major role in influencing the buying behavior of users and hence propose a video advertising strategy which takes into account the emotional impact of the videos as well as advertisements. Given a video and a set of advertisements, we identify candidate advertisement insertion points (step 1) and also identify the suitable advertisements (step 2) according to theories from marketing and consumer psychology. We formulate this two part problem as a single optimization function in a non-linear 0-1 integer programming framework and provide a genetic algorithm based solution. We evaluate CAVVA using a subjective user-study and eye-tracking experiment. Through these experiments, we demonstrate that CAVVA achieves a good balance between the following seemingly conflicting goals of (a) minimizing the user disturbance because of advertisement insertion while (b) enhancing the user engagement with the advertising content. We compare our method with existing advertising strategies and show that CAVVA can enhance the user's experience and also help increase the monetization potential of the advertising content.

Efficient Zero-Knowledge Identification Scheme with Secret Key Exchange (2006)

In an open network-computing environment, a workstation cannot be trusted to identify its users correctly to network services. Identification protocols provide an approach for the receiver of a message to ascertain its origin and to verify the identity of the sender in a distributed environment. Challenge-response identification schemes have been used to provide the authentication service but it might nonetheless reveal some partial information about the claimant's secret; an adversarial verifier might also be able to strategically select challenges to obtain responses providing such information. Zero-knowledge (ZK) protocols are designed to address these concerns, by allowing a prover to demonstrate knowledge of a secret while revealing no information to be used by the verifier to convey the demonstration of knowledge to others. In this paper we present a Fiat-Shamir-like zero-knowledge identification scheme based on the elliptic curve discrete logarithm problem. We combined our scheme with secret key exchange for subsequent conventional encryption. We expand our scheme to support mutual identification, for open network application.
Teaching Risky Stories: Remembering Mass Destruction through Children's Literature. (1995)

Obesity is a rapidly spreading endemic in almost every country of the developed world, of which Hungary is no exception. By a joint research project we aim to deepen our understanding of obesity-associated, and especially obesity-predicting changes of clinical markers (anthropometric indices, body composition, laboratory results etc.) in children, especially in teenage population. This paper presents the preliminary results of our investigations which pertain to obesity-related alterations in routine blood test parameters. For that end, we examined 340 healthy and obese children. Results show that there are differences between the routine laboratory parameters of obese and healthy subjects that are both statistically significant and medically interesting. We point out these differences in a statistically precise way, and show a method which can be efficiently used to classify children based on their laboratory parameters. This result can be used later to develop a more realistic model to predict the risk of obesity.
Social Responsibility and Sustainable Development of China’s Private Enterprises (2009)

Social responsibility is of great significance for the sustainable development of the whole society as well as every enterprise. Due to some misunderstandings held by China’s private enterprises, some problems such as the lack of honesty, infringing upon laborers’ rights and environmental pollution have been brought about. Therefore, private entrepreneurs are expected to take up their responsibility to establish the “man-oriented” concept of development, put more importance on the interests of employees, consumers as well as the whole society, hence promoting the sustainable development of our enterprises and the harmonious progress of our society.
Custom implementation of the coarse-grained reconfigurable ADRES architecture for multimedia purposes (2005)

Portable wireless multimedia approaches traditionally achieve the specified performance and power consumption with a hardwired accelerator implementation. Due to the increase of algorithm complexity (Shannon's law), flexibility is needed to achieve shorter development cycles. A coarse-grained reconfigurable computing concept for these requirements is discussed, which supports both flexible control decisions and repetitive numerical operations. The concept includes an architecture template and a compiler and simulator environment. The architecture provides flexible time-multiplexing of code for high-performance data processing while keeping the configuration bandwidth and power requirements low. The purpose of this study is to use the coarse-grained architecture for H264/AVC in order to determine at the physical level whether reconfigurable computing, high-performance and low-power can be obtained.
Shock-induced brittle cracking in HVPE-GaN processed by laser lift-off techniques (2013)

A study on brittle cracking in GaN films processed by laser lift-off is presented. Two kinds of cracks were found in the N-polar face of GaN after the laser lift-off process, namely perpendicular cracks along the {1 −1 0 0} planes and lateral cracks along the (0 0 0 −1) plane, respectively. Single-shot laser damage is studied to understand the cracking mechanism. The damage morphology indicates that the GaN material on the edge of the laser ablation area experiences three loading modes: shear stress PS, longitudinal compressive stress PL and transverse tensile stress PT. Under shock PL, lateral cracks likely appear and extend from the illuminated region along the interface in mode I. Furthermore, two different kinds of perpendicular cracks were found, namely shear cracks (PC I) and deflection cracks (PC II). A strong PS gives rise to PC I while a cooperative action of PL and PT results in PC II. In addition, there exist a critical effective spot size dPth and a critical ratio of the laser spot size dL to the effective spot size dP, when cracks occur over them.
Hemodynamic and Thermal Responses to Head and Neck Cooling in Men and Women (1995)

Personal cooling systems are used to alleviate symptoms of multiple sclerosis and to prevent increased core temperature during daily activities. Configurations of these systems include passive ice vests and circulating liquid cooling garments (LCGs) in the forms of vests, cooling caps and combined head and neck cooling systems. However, little information is available oil the amount or heat that can be extracted from the body with these systems or the physiologic changes produced by routine operation of these systems. The objective of this study was to determine the operating characteristics and the physiologic change, produced by short term use of one commercially available thermal control system.
Reduced complexity decision feedback equalization for multipath channels with large delay spreads (1999)

Two modified decision feedback equalization (DFE) structures are presented for the efficient equalization of long sparse channels with strong precursor, such as those encountered in high-speed communications over multipath channels with large delay spread. Unlike the conventional DFE, these structures allow the channel's sparseness to be exploited by simple tap allocation, before the sparseness is degraded by feedforward filtering. Both structures yield large reductions in complexity while maintaining performance comparable to the conventional DPE, hence overcoming a key computational bottleneck when equalizers are implemented in hardware for speed. Fast channel estimate-based algorithms for computing the modified DFE coefficients are derived. Simulation results are presented for data rates and channel profiles of the type considered for the proposed North American high definition television (HDTV) terrestrial broadcast mode.
Deceptively simple but simply deceptive – <i>Caenorhabditis elegans</i> lifespan studies: Considerations for aging and antioxidant effects (2009)

The nematode worm Caenorhabditis elegans (C. elegans) is increasingly popular as a model organism for aging studies as well as for testing antioxidants and other compounds for effects on longevity. However, results in the literature are sometimes confusing and contradictory. This review introduces C. elegans as a model organism, discusses aspects that make it attractive for aging and antioxidant research, and addresses some problems and potential artifacts.
Self-Activation Mechanism Investigations on Large K<sub>2</sub>CO<sub>3</sub>-Doped Li<sub>4</sub>SiO<sub>4</sub> Sorbent Particles (2015)

This work investigated the self-activation behavior of large K2CO3-doped Li4SiO4 sorbent particles. In this self-activation mechanism, the sorption ability increased as the number of cycles increased. After the sorption–desorption cycles occurred, the sorption ability of the K2CO3-doped Li4SiO4 sorbent was remarkably enhanced from approximately 2.0 mmol CO2/g sorbent to approximately 5.0 mmol CO2/g sorbent at 565 °C in 10 vol % CO2 atmosphere. The fresh and used sorbents were then characterized through N2 adsorption and SEM methods. Results showed that the average pore size increased from 7 to 32 nm and the surface microstructure changed from dense to porous, because the molten eutectic mixture formed by Li2CO3 and Li2SiO3 can facilitate CO2 diffusion. The formed CO2 diffusion channel can provide more CO2 accessibility; this channel can also reduce the CO2 diffusion resistance through the product layer. Therefore, the sorption ability of the sorbent is enhanced. Meanwhile, the effects of the self-activation temperature were also investigated and the results revealed that the optimal self-activation temperature is 615 °C. Furthermore, under critical conditions, the self-activated sorbent performed more efficiently than the fresh sample. At 450 °C under 10 vol % CO2 atmosphere, the sorption capacity of the self-activated sorbent was approximately 20 times higher than that of the fresh sample. Finally, a pore–core model was also proposed to illustrate the K2CO3-doped Li4SiO4 self-activation mechanism.
Making the hydrogen evolution reaction in polymer electrolyte membrane electrolysers even faster (2016)

Although the hydrogen evolution reaction (HER) is one of the fastest electrocatalytic reactions, modern polymer electrolyte membrane (PEM) electrolysers require larger platinum loadings (∼0.5-1.0 mg cm(-2)) than those in PEM fuel cell anodes and cathodes altogether (∼0.5 mg cm(-2)). Thus, catalyst optimization would help in substantially reducing the costs for hydrogen production using this technology. Here we show that the activity of platinum(111) electrodes towards HER is significantly enhanced with just monolayer amounts of copper. Positioning copper atoms into the subsurface layer of platinum weakens the surface binding of adsorbed H-intermediates and provides a twofold activity increase, surpassing the highest specific HER activities reported for acidic media under similar conditions, to the best of our knowledge. These improvements are rationalized using a simple model based on structure-sensitive hydrogen adsorption at platinum and copper-modified platinum surfaces. This model also solves a long-lasting puzzle in electrocatalysis, namely why polycrystalline platinum electrodes are more active than platinum(111) for the HER.
Acylhomoserine Lactone Synthase Activity of the <i>Vibrio fischeri</i> AinS Protein (1999)

Acylhomoserine lactones, which serve as quorum-sensing signals in gram-negative bacteria, are produced by members of the LuxI family of synthases. LuxI is a Vibrio fischeri enzyme that catalyzes the synthesis of N-(3-oxohexanoyl)-L-homoserine lactone from an acyl-acyl carrier protein and S-adenosylmethionine. Another V. fischeri gene, ainS, directs the synthesis of N-octanoylhomoserine lactone. The AinS protein shows no significant sequence similarity with LuxI family members, but it does show sequence similarity with the Vibrio harveyi LuxM protein. The luxM gene is required for the synthesis of N-(3-hydroxybutyryl)-L-homoserine lactone. To gain insights about whether AinS and LuxM represent a second family of acylhomoserine lactone synthases, we have purified AinS as a maltose-binding protein (MBP) fusion protein. The purified MBP-AinS fusion protein catalyzed the synthesis of N-octanoylhomoserine lactone from S-adenosylmethionine and either octanoyl-acyl carrier protein or, to a lesser extent, octanoyl coenzyme A. With the exception that octanoyl coenzyme A served as an acyl substrate for the MBP-AinS fusion protein, the substrates for and reaction kinetics of the MBP-AinS fusion protein were similar to those of the several LuxI family members previously studied. We conclude that AinS is an acylhomoserine lactone synthase and that it represents a second family of such enzymes.
An Adaptive Energy-Efficient and Low-Latency Mac Protocol for Wireless Sensor Networks (2007)

In this paper, an adaptive energy-efficient and low-latency MAC (L-MAC) protocol for wireless sensor networks is proposed. In this protocol, nodes have three modes-sleeping, receiving and sending. Each node goes to sleep periodically to save energy. L-MAC delays the receiving and sending period hop by hop, so that when one node is in sending mode, its lower-hop node is in receiving mode. After receiving a message from upper- hop node, each node can transmit it to lower-hop node in the sequent sending period. Therefore, the multi-hop end-to-end delay due to periodical sleeping is reduced greatly. Furthermore, an adaptive sleeping scheme which makes the nodes with lower traffic have longer time to sleep is adopted to save more energy. Simulation results show that L-MAC achieves lower energy consumption and latency than traditional contention-based protocols.
A first-in-human phase I study to evaluate the pan-PI3K inhibitor GDC-0941 administered QD or BID in patients with advanced solid tumors (2009)

3501 Background: The PI3K-PTEN-AKT signaling pathway is deregulated in a wide variety of cancers. GDC-0941 is a potent and selective oral inhibitor of the class I PI3K with 3 nM IC50 for the p110-alpha subunit in vitro and 28 nM IC50 in a cell-based pAKT assay and demonstrates broad activity in breast, ovarian, lung, and prostate cancer models. Methods: A Phase I dose escalation study using a 3+3 design was initiated in patients (pts) with solid tumors. GDC-0941 was given on d1, followed by 1 wk washout to study single-dose PK and PD markers. GDC-0941 was then administered qd on a 3 wk on, 1 wk off, schedule. Steady-state PK and PD were evaluated after 1 wk of continuous dosing. A separate concurrent dose-escalation arm with bid dosing was initiated after the third qd cohort. Results: Nineteen pts have been enrolled in 5 successive dose-escalation cohorts in the qd arm with dose levels up to 80 mg daily. Seven pts were enrolled in 2 cohorts in the bid arm at total daily doses of 60 and 80 mg. The most frequently reported drug-related AEs were Grade 1/2 nausea, fatigue, diarrhea, peripheral edema, and dysgeusia; no drug related grade >3 events have been reported. PK data suggest dose-proportional increases in Cmax and AUC. Potential signs of anti-tumor activity have been observed with a soft tissue sarcoma pt on-study for >176 days with stable disease (30 mg qd), an ovarian cancer pt with an on-study 2.8-fold decrease in CA-125 response to normal levels (30 mg bid) and a pt with endometrial cancer with a decrease in tumor FDG-PET uptake (80 mg qd). Conclusions: GDC-0941 is generally well-tolerated with potential signs of anti-tumor activity. Preliminary PK data suggest dose-proportional increases in exposure over the dose levels evaluated. Dose-escalation on both the qd and bid schedules continues with updated data to be presented. [Table: see text]
Influence of Culture Media on Biofilm Formation by<i>Candida</i>Species and Response of Sessile Cells to Antifungals and Oxidative Stress (2015)

The aims of the study were to evaluate the influence of culture media on biofilm formation by C. albicans, C. glabrata, C. krusei, and C. parapsilosis and to investigate the responses of sessile cells to antifungals and reactive oxygen species (ROS) as compared to planktonic cells. For biofilm formation, the Candida species were grown at different periods of time in YP or YNB media supplemented or not with 0.2 or 2% glucose. Sessile and planktonic cells were exposed to increasing concentrations of antifungals, H2O2, menadione or silver nanoparticles (AgNPs). Biofilms were observed by scanning electron microscopy (SEM) and quantified by the XTT assay. C. albicans formed biofilms preferentially in YPD containing 2% glucose (YPD/2%), C. glabrata in glucose-free YNB or supplemented with 0.2% glucose (YNB/0.2%), while C. krusei and C. parapsilosis preferred YP, YPD/0.2%, and YPD/2%. Interestingly, only C. albicans produced an exopolymeric matrix. This is the first report dealing with the in vitro effect of the culture medium and glucose on the formation of biofilms in four Candida species as well as the resistance of sessile cells to antifungals, AgNPs, and ROS. Our results suggest that candidiasis in vivo is a multifactorial and complex process where the nutritional conditions, the human immune system, and the adaptability of the pathogen should be considered altogether to provide an effective treatment of the patient.
