Placement with symmetry constraints for analog layout design using TCG-S (2005)

In order to handle device matching for analog circuits, some pairs of modules need to be placed symmetrically with respect to a common axis. In this paper, we deal with the module placement with symmetry constraints for analog design using the Transitive Closure Graph-Sequence (TCG-S) representation. Since the geometric relationships of modules are transparent to TCG-S and its induced operations, TCG-S has better flexibility than previous works in dealing with symmetry constraints. We first propose the necessary and sufficient conditions of TCG-S for symmetry modules. Then, we propose a polynomial-time packing algorithm for a TCG-S with symmetry constraints. Experimental results show that the TCG-S based algorithm results in the best area utilization.

The electrical resistivity, electron concentration, and mobility of ${\mathrm{Hg}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Fe}}_{\mathrm{x}}$Se are reported for 4.2<T<300 K and for 0.0001<x<0.12. The data are interpreted within an electronic band-structure model that assumes the existence of resonant donors (due to the presence of Fe ions) whose ground-state energy coincides with the conduction-band continuum. The electron-concentration data enable determination of the donor energy as a function of the temperature and crystal composition. Unexpectedly high values of the low-temperature electron mobility for \ensuremath{\sim}0.0003\ensuremath{\le}x\ensuremath{\le}0.01 indicate a reduction of the charged-impurity scattering rate at these temperatures. This effect is interpreted in terms of a spatial ordering of charges within the Fe-related impurity system.
Terlipressin facilitates transport of septic patients treated with norepinephrine. (2006)

Our data suggest that terlipressin is effective in septic shock. Because it is long-acting and necessitates less titration it might be indicated for patient transportation.

Analysis of PFG Anomalous Diffusion via Real-Space and Phase-Space Approaches (2018)

Pulsed-field gradient (PFG) diffusion experiments can be used to measure anomalous diffusion in many polymer or biological systems. However, it is still complicated to analyze PFG anomalous diffusion, particularly the finite gradient pulse width (FGPW) effect. In practical applications, the FGPW effect may not be neglected, such as in clinical diffusion magnetic resonance imaging (MRI). Here, two significantly different methods are proposed to analyze PFG anomalous diffusion: the effective phase-shift diffusion equation (EPSDE) method and a method based on observing the signal intensity at the origin. The EPSDE method describes the phase evolution in virtual phase space, while the method to observe the signal intensity at the origin describes the magnetization evolution in real space. However, these two approaches give the same general PFG signal attenuation including the FGPW effect, which can be numerically evaluated by a direct integration method. The direct integration method is fast and without overflow. It is a convenient numerical evaluation method for Mittag-Leffler function-type PFG signal attenuation. The methods here provide a clear view of spin evolution under a field gradient, and their results will help the analysis of PFG anomalous diffusion.
A Survey of Intrusion Detection Systems in Wireless Sensor Networks (2013)

Wireless Sensor Networking is one of the most promising technologies that have applications ranging from health care to tactical military. Although Wireless Sensor Networks (WSNs) have appealing features (e.g., low installation cost, unattended network operation), due to the lack of a physical line of defense (i.e., there are no gateways or switches to monitor the information flow), the security of such networks is a big concern, especially for the applications where confidentiality has prime importance. Therefore, in order to operate WSNs in a secure way, any kind of intrusions should be detected before attackers can harm the network (i.e., sensor nodes) and/or information destination (i.e., data sink or base station). In this article, a survey of the state-of-the-art in Intrusion Detection Systems (IDSs) that are proposed for WSNs is presented. Firstly, detailed information about IDSs is provided. Secondly, a brief survey of IDSs proposed for Mobile Ad-Hoc Networks (MANETs) is presented and applicability of those systems to WSNs are discussed. Thirdly, IDSs proposed for WSNs are presented. This is followed by the analysis and comparison of each scheme along with their advantages and disadvantages. Finally, guidelines on IDSs that are potentially applicable to WSNs are provided. Our survey is concluded by highlighting open research issues in the field.
Resolution of focus of attention using gaze direction estimation and saliency computation (2009)

Modeling the user's attention is useful for responsive and interactive systems. This paper proposes a method for establishing joint visual attention between an experimenter and an intelligent agent. A rapid procedure is described to track the 3D head pose of the experimenter, which is used to approximate the gaze direction. The head is modeled with a sparse grid of points sampled from the surface of a cylinder. We then propose to employ a bottom-up saliency model to single out interesting objects in the neighborhood of the estimated focus of attention. We report results on a series of experiments, where a human experimenter looks at objects placed at different locations of the visual field, and the proposed algorithm is used to locate target objects automatically. Our results indicate that the proposed approach achieves high localization accuracy and thus constitutes a useful tool for the construction of natural human-computer interfaces.
Inhaled magnesium sulfate in the treatment of acute asthma (2005)

Nebulised inhaled magnesium sulfate in addition to beta2-agonist in the treatment of an acute asthma exacerbation, appears to have benefits with respect to improved pulmonary function in patients with severe asthma and there is a trend towards benefit in hospital admission. Heterogeneity between trials included in this review precludes a more definitive conclusion.

Requirements for leaf position accuracy for dynamic multileaf collimation (2000)

Intensity modulated radiation therapy can be achieved by driving the leaves of a multileaf collimator (MLC) across an x-ray therapy beam. Algorithms to generate the required leaf trajectories assume that the leaf positions are exactly known to the MLC controller. In practice, leaf positions depend upon calibration accuracy and stability and may vary within set tolerances. The purpose of this study was to determine the effects of potential leaf position inaccuracies on intensity modulated beams. Equations are derived which quantify the absolute error in delivered monitor units given a known error in leaf position. The equations have been verified by ionization chamber measurements in dynamically delivered flat fields, comparing deliveries in which known displacements have been applied to the defined leaf positions with deliveries without displacements applied. The equations are then applied to two clinical intensity modulations: an inverse planned prostate field and a breast compensating field. It is shown that leaf position accuracy is more critical for a highly modulated low-dose intensity profile than a moderately modulated high-dose intensity profile. Suggestions are given regarding the implications for quality control of dynamic MLC treatments.
Supporting Acute Appendicitis Diagnosis: A Pre-Clustering-Based Classification Technique (2010)

Service quality and cost containment represent two critical challenges in healthcare management. Toward that end, acute appendicitis, a common surgical condition, is important and requires timely, accurate diagnosis. The diverse and atypical symptoms make such diagnoses difficult, thus resulting in increased morbidity and negative appendectomy. While prior research has recognized the use of classification analysis to support acute appendicitis diagnosis, the skewed distribution of the cases pertaining to positive or negative acute appendicitis has significantly constrained the effectiveness of the existing classification techniques. In this study, we develop a pre-clustering-based classification (PCC) technique to address the skewed distribution problem common to acute appendicitis diagnosis. We empirically evaluate the proposed PCC technique with 574 clinical cases of positive and negative acute appendicitis obtained from a tertiary medical center in Taiwan. Our evaluation includes tradition support vector machine, a prevalent resampling classification technique, Alvarado scoring system, and a multi-classifier committee for performance benchmark purposes. Our results show the PCC technique more effective and less biased than the benchmark techniques, without favoring the positive or negative class.
Hydrolytic degradation of poly(ethylene terephthalate) (2006)

Abstract Molecular weight is an important factor in the processing of polymer materials, and it should be well controlled to obtain desired physical properties in final products for end‐use applications. Degradation processes of all kinds, including hydrolytic, thermal, and oxidative degradations, cause chain scission in macromolecules and a reduction in molecular weight. The main purpose of this research is to illustrate the importance of degradation in the drying of poly(ethylene terephthalate) (PET) before processing and the loss of weight and mechanical properties in textile materials during washing. Several techniques were used to investigate the hydrolytic degradation of PET and its effect on changes in molecular weight. Hydrolytic conditions were used to expose fiber‐grade PET chips in water at 85°C for different periods of time. Solution viscometry and end‐group analysis were used as the main methods for determining the extent of degradation. The experimental results show that PET is susceptible to hydrolysis. Also, we that as the time of retention in hydrolytic condition increased, the molecular weight decreases, but the rate of chain cleavage decreased to some extent, at which point there was no more sensible degradation. The obtained moisture content data confirmed the end‐group analysis and viscometry results. Predictive analytical relationships for the estimation of the extent of degradation based on solution viscosity and end‐group analysis are presented. © 2006 Wiley Periodicals, Inc.

Peanut lectin-binding sites in large bowel carcinoma. (1982)

Peanut lectin is known to bind to B-D-Gal-(1 leads to 3)-D-GalNac which provides antigenic determination for the T (TAg) blood group antigen. We examined 33 rectosigmoid carcinomas and 15 corresponding controls for their ability to express peanut lectin-binding sites. In controls one could localize TAg to the supranuclear portion of the cell, however, in cancers one noticed a cytostructural relocalization of TAg with the following two major patterns: localization to the region of the glycocalyx and localization intracytoplasmically in the apical portion of the cell. These two patterns were associated with glandular differentiation. Less frequently noted or in association with the above was a mucin glob-like pattern and/or a fine diffuse intracytoplasmic pattern associated with solid, nonglandular areas. The more poorly differentiated cancers less frequently expressed peanut lectin-binding sites. Benign (nontransitional zone) epithelium in those patients whose tumor expressed TAg was negative for peanut lectin-binding sites in 66 per cent of the cases. Reduced tumoral glycosyltransferases may explain this increased synthesis of TAg in cancers as compared with controls, if one considers TAg to be an incomplete glycoprotein of the MN blood group system.
Buoyancy Effects in Fluids (1973)

The phenomena treated in this book all depend on the action of gravity on small density differences in a non-rotating fluid. The author gives a connected account of the various motions which can be driven or influenced by buoyancy forces in a stratified fluid, including internal waves, turbulent shear flows and buoyant convection. This excellent introduction to a rapidly developing field, first published in 1973, can be used as the basis of graduate courses in university departments of meteorology, oceanography and various branches of engineering. This edition is reprinted with corrections, and extra references have been added to allow readers to bring themselves up to date on specific topics. Professor Turner is a physicist with a special interest in laboratory modelling of small-scale geophysical processes. An important feature is the superb illustration of the text with many fine photographs of laboratory experiments and natural phenomena.
Highly efficient blue organic light-emitting diodes using dual emissive layers with host-dopant system (2013)

We fabricated highly efficient blue organic light-emitting diodes (OLEDs) by designing differing emitting layer structures with fluorescent host and dopant materials of 4,4-bis (2,2-diphenylyinyl)-1,10-biphenyl and 9,10-bis (2-naphthyl) anthracene as host materials and 4,4’-bis (9-ethyl-3-carbazovinylene)-1,1’biphenyl (BCzVBi) as a dopant material to demonstrate electrical and optical improvements. Best enhancement in luminance and luminous efficiency were achieved by a quantum well structure in device F with 8668 cd/m 2 at 8 V and 5.16 cd/A at 103.20 mA/cm 2 , respectively. Among the blue OLED devices doped by BCzVBi, device B emits the deepest blue emission with Commission Internationale de l’É clairage coordinates of (0.157, 0.117) at 8 V.
Kampen om Danmarks omdømme 1945-2010 (2014)

Staten har i et vist omfang altid beskæftiget sig med Danmarks omdømme. Efter 2. verdenskrig var statens hovedfokus dog på statens sikkerhedspolitiske omdømme, mens Danmarks økonomiske og kulturelle omdømme i højere grad var overladt til ikke-statslige aktører. Først i slutningen af den kolde krig rykkes der for alvor på denne fordeling med indsatsen i de baltiske lande i forbindelse med løsrivelsesprocessen fra Sovjetunionen. Samtidig skete der et skift, hvor staten tidligere hovedsagligt havde bekymret sig om, hvordan landet blev opfattet sikkerhedspolitisk, så var det ved afslutningen af den kolde krig og særligt i perioden efter den kolde krig hovedsagligt Danmarks omdømme set i et økonomisk perspektiv, der blev fokuseret på.
Characterization and optoelectronic properties of p-type N-doped CuAlO2 films (2007)

This letter reports a technique for increasing the carrier concentration and the conductivity of the p-type CuAlO2 through doping the material with nitrogen. The x-ray photoelectron spectroscopy and the optical band gap analyses suggested that the nitrogen atoms occupying the interstitial sites of the delafossite structure provided the p-type CuAlO2 with an impurity energy level in the energy gap. It was also found that the N-doped CuAlO2 film had its optimum conduction properties when the dopant level reached 1.1at.%. Here, the carrier concentration was raised from 4.81×1016 in the undoped film to 2.13×1017cm−3 in the doped film, and the corresponding film’s conductivity was increased from 3.8×10−2to5.4×10−2(Ωcm)−1, as compared with the undoped CuAlO2 film.
Semantic access of frontal face images: the expression-invariant problem (2000)

Semantic queries to a database of images are more desirable than low-level feature queries, because they facilitate the user's task. One such approach is object-related image retrieval. In the context of face images, it is of interest to retrieve images based on people's names and facial expressions. However, when images of the database are allowed to appear at different facial expressions, the face recognition approach encounters the expression-invariant problem, i.e. how to robustly identify a person's face for which its learning and testing face images differ in facial expression. This paper presents a new local, probabilistic approach that accounts for this (as well as other previous studied) difficulty.
<title>Recent Applications Of Electronic Vision To Noncontact Automatic Inspection</title> (1979)

The OPTOMATION TM Instrument System provides on-line capability for 100% non-contact inspection of parts or assemblies on high speed production lines. System operation is based on measurements which are made by extracting key visual features or discriminants from the image derived from a solid state Charge Injection Device (CID) camera, comparing those measurements with a set of predetermined values which establish acceptance or rejection criteria, and generating output decision signals to drive the system under control. In this paper, performance characteristics of the PN2303 OPTOMATION TM Instrument System are outlined. In addition, several specific system applications are described.

Capacity of Slotted ALOHA in Rayleigh-Fading Channels (1987)

Fading channels may improve the capacity of slottedALOHA networks. Rayleigh fading and spatially distributed packet transmitters diminish mutual packet interference and thus reduce the average blocking probability of a shared receiver. A transmission model, combining Poisson statistics of the offered data traffic with Rayleigh statistics for the fading channel, is developed. Analytical and numerical results are presented, indicating significant improvements to signaling in cellular mobile networks and in packet radio systems with fading radio channels.
Therapy for sarcoidosis: evidence-based recommendations (2011)

The options for treatment of sarcoidosis have expanded. In this article, we outline a stepwise approach to treatment. Recommendations for treatment are based on available evidence. While corticosteroids remain the treatment of choice for initial systemic therapy, other agents have been shown to be steroid sparing, and therefore useful for long-term management. In addition, new agents have proved to be useful for patients with refractory disease.
Timing Performance Control in Web Server Systems Utilizing Server Internal State Information (2005)

How to effectively allocate system resource to meet the service level agreement (SLA) of Web servers is a challenging problem. In this paper, we propose an improved scheme for autonomous timing performance control in Web servers under highly dynamic traffic loads. We devise a novel delay regulation technique called queue length model based feedback control utilizing server internal state information to reduce response time variance in presence of bursty traffic. Both simulation and experimental studies using synthesized workloads and real-world Web traces demonstrate the effectiveness of the proposed approach

Physico-Chemical Characteristics and Functional Properties of Chitin and Chitosan Produced by Mucor circinelloides Using Yam Bean as Substrate (2011)

Microbiological processes were used for chitin and chitosan production by Mucor circinelloides (UCP 050) grown in yam bean (Pachyrhizus erosus L. Urban) medium. The polysaccharides were extracted by alkali-acid treatment and structural investigations by X-ray diffraction, Fourier transform IR analysis, viscosity and thermal analysis by TG, DTG, and DTA were done. The highest biomass yield (20.7 g/L) was obtained at 96 hours. The highest levels of chitosan (64 mg/g) and chitin (500 mg/g) were produced at 48 and 72 hours, respectively. It was demonstrated that yam bean shows great potential as an economic medium and it is possible to achieve a good yield of chitosan with chemical properties that enable its use in biotechnological applications.
