Area-Based COI-Referred Rotor Angle Index for Transient Stability Assessment and Control of Power Systems

This paper describes an index for judging the severity of transient events of power systems in simulation. The proposed transient stability index, known as the area-based COI-referred rotor angle index, is developed by considering the fact that a large-sized power system is divided into several areas according to the coherency of generators in a particular area. It can be assumed that an equivalent single large machine can represent all the generators in that area. Thus, the assessment of rotor angles for all generators can be simplified by only assessing the index of areas in a power system. The effectiveness of the proposed index in assessing the stability of power systems and its ability in pinpointing the weakest area in the power system is analyzed. Furthermore, this paper developed an emergency control scheme known as the combined UFLS and generator tripping in order to stabilize the system when unstable faults occurred in a power system. The proposed index is used to identify the generator to be tripped when the developed emergency control scheme operates. The performance of the proposed index and the combined UFLS and generator tripping scheme are evaluated on the IEEE 39-bus test system.

Par analyse de restriction selective, les bandes artificielles pouvaient etre identifiees avec certitude. L'analyse de la sequence d'ADN de deux bandes artificielles selectionnees a revele de faibles similarites par rapport aux sequences-cible correspondantes (promoteur 35S et terminateur NOS). L'origine des bandes artificielles ne pouvait meme pas etre revelee par comparaison entre des banques de donnees.
phenocopies for extrachromosomal DNA processing due to prolonged titration of RecBCD enzyme on damaged Escherichia coli chromosome

The RecBCD enzyme of Escherichia coli consists of three subunits RecB, RecC and RecD. RecBCD enzyme activities are regulated by its interaction with recombination hotspot Chi. Biochemical and genetic evidence suggest that interaction with Chi affects RecD subunit, and that RecD polypeptide overproduction antagonizes this interaction, suggesting that intact RecD replaces a Chi-modified one. We used bacteria with fragmented chromosomes due to double-strand breaks inflicted by UV and γ-irradiation to explore in which way increased concentrations of RecBCD’s individual subunits affect DNA metabolism. We confirmed that RecD overproduction alters RecBCD-dependent DNA repair and degradation in E. coli. Also, we found that RecB and RecC overproduction did not affect these processes. To determine the basis for the effects of RecD polypeptide overproduction, we monitored activities of RecBCD enzyme on γ-damaged chromosomal DNA and, in parallel, on λ and T4 2 phage DNA duplexes provided at intervals. We found that γ-irradiated wild-type bacteria became transient, and RecD overproducers permanent recB/C phenocopies for processing phage DNA that is provided in parallel. Since this inability of irradiated bacteria to process extrachromosomal DNA substrates coincided in both cases with ongoing degradation of chromosomal DNA, which lasted much longer in RecD overproducers, we were led to conclude that the RecB/C phenotype is acquired as a consequence of RecBCD enzyme titration on damaged chromosomal DNA. This conclusion was corroborated by our observation that no inhibition of RecBCD activity occurs in γ-irradiated RecBCD overproducers. Together, these results strongly indicate that RecD overproduction prevents dissociation of RecBCD enzyme from DNA substrate and thus increases its processivity. © 2005 Elsevier SAS.

The Symptom of Stress Incontinence Caused by Pregnancy Or Delivery in Primiparas

Three hundred five primiparas were interviewed repeatedly about stress incontinence before and during pregnancy and after delivery. Eleven (4%) had stress incontinence before pregnancy and 98 (32%) during pregnancy, whereas 21 (7%) developed it after delivery. According to the International Continence Society definition, the corresponding frequencies were one (0.3%), three (1%), and one (0.3%), respectively. Obstetric factors such as length of the second stage of labor, head circumference, birth weight, and episiotomy seemed to be associated with, whereas cesarean delivery seemed to protect against, the development of stress incontinence after delivery. Three months after delivery, the statistically significant influence of the obstetric factors had vanished, as stress incontinence had disappeared in most women. However, 1 year after delivery eight of 292 women (3%) had stress incontinence, three with onset during pregnancy and five with onset after delivery. Three of these eight had stress incontinence according to International Continence Society criteria; four women wanted treatment. The symptom of stress incontinence occurs as a natural consequence of pregnancy and delivery and generally resolves in the puerperium. However, pregnancy and delivery carry a small risk (1% or less) of initiating persistent stress incontinence. The importance of various obstetric factors seems transient and their etiologic role remains unclear.

Dissimilar patterns of degeneration in brain following four different addictive stimulants

PATTERNS of neural degeneration were compared following continuous administration of four drugs of addiction, each of which induces model psychoses in chronic addicts. D-amphetamine (D-Amph), cocaine (Coc), or phencyclidine (PCP) were administered continuously over a 5-day period. Both D-Amph and Coc induced pronounced degeneration in fasciculus retroflexus, but only D-Amph further induced substantial degeneration in striatum. Continuous PCP produced entirely different degeneration largely confined to the posterior entorhinal cortex, ventral dentate gyrus, and cingulate cortex. Methamphetamine (Meth) administered in the very high dose but less prolonged drug regimen often employed in studies of dopamine toxicity induced pronounced degeneration in striatum, but widespread degeneration in many other regions as well. These results indicate that drugs of abuse with psychotomimetic properties induce distinctively different patterns of neural degeneration, a finding with implications for theories of addiction and psychosis. They predict two different anatomical loci for alterations in psychosis: fasciculus retroflexus and ventral parahippocampus and hippocampus.
Using the Internet for speech research: an evaluative study examining affect in speech

The Internet has rarely been used in auditory perception studies due to concerns about standardisation and calibration across different systems and settings. However, not all auditory research is based on the investigation of fine-grained differences in auditory thresholds. Where meaningful ‘real-world’ listening, for instance the perception of speech, is concerned, the Internet may be a more appropriate and ecologically valid setting to collect data. This study compared affective ratings of low-pass-filtered infant-, foreigner- and British adult-directed speech obtained with traditional methods in the laboratory, with those obtained from an Internet sample. Dropout rates and demographic distribution of participants in the Internet condition were also assessed. The results show that affective ratings were similar for both the Internet and laboratory samples. These findings indicate the viability of Internet-based research into affective speech perception and suggest that precise acoustic environmental control may not always be necessary.
IQ-motif selectivity in human IQGAP2 and IQGAP3: binding of calmodulin and myosin essential light chain

The IQGAP [IQ-motif-containing GAP (GTPase-activating protein)] family members are eukaryotic proteins that act at the interface between cellular signalling and the cytoskeleton. As such they collect numerous inputs from a variety of signalling pathways. A key binding partner is the calcium-sensing protein CaM (calmodulin). This protein binds mainly through a series of IQ-motifs which are located towards the middle of the primary sequence of the IQGAPs. In some IQGAPs, these motifs also provide binding sites for CaM-like proteins such as myosin essential light chain and S100B. Using synthetic peptides and native gel electrophoresis, the binding properties of the IQ-motifs from human IQGAP2 and IQGAP3 have been mapped. The second and third IQ-motifs in IQGAP2 and all four of the IQ-motifs of IQGAP3 interacted with CaM in the presence of calcium ions. However, there were differences in the type of interaction: while some IQ-motifs were able to form complexes with CaM which were stable under the conditions of the experiment, others formed more transient interactions. The first IQ-motifs from IQGAP2 and IQGAP3 formed transient interactions with CaM in the absence of calcium and the first motif from IQGAP3 formed a transient interaction with the myosin essential light chain Mlc1sa. None of these IQ-motifs interacted with S100B. Molecular modelling suggested that all of the IQ-motifs, except the first one from IQGAP2 formed α-helices in solution. These results extend our knowledge of the selectivity of IQ-motifs for CaM and related proteins.
Asymptotic design of quantization and bit allocation for distributed estimation in wireless sensor networks

This paper investigates the schemes of asymptotically optimal quantization and bit allocation for distributed estimation in wireless sensor networks in which a total bit rate constraint is imposed. Because there is no communication among all sensors, quantizers for observations need to be designed separately. The Lloyd‐Max quantizer is shown to be asymptotically optimal for each sensor. Moreover, it is shown that the level number of asymptotically optimal quantization for sensors is proportional to the signal‐to‐noise ratio, which is determined by the variances of observation and noise. Because the original quantized minimum mean‐square error estimator often corresponds to a high computational cost when a large number of sensors are active, in our work, an asymptotically equivalent algorithm of iterative quantized estimator (IQE), which enjoys a low computational cost, is proposed. In addition, an IQE algorithm can be applied to wireless sensor networks with delay or packet loss. Simulation results of this work indicate that the effectiveness of our IQE algorithm is obvious; that is, a significant improvement of estimation performance is achieved by using the optimal bit allocation when comparing with the uniform bit allocation.

Shirt pattern recognizing and tracking behavior analysis using SURF on the moving human target

In the field of human following using mobile robot, human as the object for the detection is not the only requirement to be considered. Besides detection, continuous tracking and recognition is also another important criteria. In order to track and recognize a human, an effective algorithm needed to be implemented in the system. Speed Up Robust Feature (SURF) algorithm is a fast and robust algorithm for local, similarity invariant representation and comparison which mainly used for image analysis. In this paper we made the analysis using the SURF on the moving human target based on the shirts pattern and the results were shown in the discussion.
Rd as a Control Parameter to Explore Affective Correlates of the Tense-Lax Continuum

This study uses the Rd glottal waveshape parameter to simulate the phonatory tense-lax continuum and to explore its affective correlates in terms of activation and valence. Based on a natural utterance which was inverse filtered and sourceparameterised, a range of synthesized stimuli varying along the tense-lax continuum were generated using Rd as a control parameter. Two additional stimuli were included, which were versions of the most lax stimuli with additional creak (laxcreaky voice). In a listening test, participants chose an emotion from a set of affective labels and indicated its perceived strength. They also indicated the naturalness of the stimulus and their confidence in their judgment. Results showed that stimuli at the tense end of the range were most frequently associated with angry, at the lax end of the range the association was with sad, and in the intermediate range, the association was with content. Results also indicate, as was found in our earlier work, that a particular stimulus can be associated with more than one affect. Overall these results show that Rd can be used as a single control parameter to generate variation along the tense-lax continuum of phonation.
Redox priming of the insulin receptor β‐chain associated with altered tyrosine kinase activity and insulin responsiveness in the absence of tyrosine autophosphorylation

Induction of tyrosine kinase activity of the insulin receptor (IR) β‐chain is believed to require its autophosphorylation at Tyr1162, Tyr1163, and Tyr1158. However, the mechanism of the initial phosphorylation is poorly understood. We show that treatment of IR‐transfected Chinese hamster ovary cells with antioxidants inhibits insulin responsiveness. Conversely, partial inhibition of glutathione biosynthesis by buthionine sulfoximine (BSO) and glutathione reductase by 1,3‐bis‐(2‐chloroethyl)‐1‐nitrosourea (BCNU), i.e., procedures that intracellularly induce mildly oxidative conditions, caused a decrease in IR β‐chain sulfhydryl groups and enhanced synergistically the induction of IR tyrosine phosphorylation by insulin. The IR β‐chain from cells treated with BSO/ BCNU in the absence of insulin was not detectably tyrosine phosphorylated, but nevertheless was functionally altered, as demonstrated in vitro by a moderate kinase activity at low ATP concentrations (5 nM) and a strong kinase activity at 25 μM ATP. This activity was found to be specific for tyrosine (not for serine or threonine), and tryptic peptide maps indicated that it is more selective than that induced by insulin. Moreover, the kinase activity from BSO/BCNU‐treated cells showed a spontaneous decay that was not prevented by the phosphatase inhibitor vanadate. Together, these results suggest that optimal insulin responsiveness may require a process of ‘redox priming’ of the IR β‐chain that involves structural and functional changes in the absence of detectable tyrosine phosphorylation of the β‐chain. —Schmid, E. , El Benna, J., Galter, D. , Klein, G. , Dröge, W.

Indonesian propolis: chemical composition, biological activity and botanical origin

From a biologically active extract of Indonesian propolis from East Java, 11 compounds were isolated and identified: four alk(en)ylresorcinols (obtained as an inseparable mixture) (1–4) were isolated for the first time from propolis, along with four prenylflavanones (6–9) and three cycloartane-type triterpenes (5, 10 and 11). The structures of the components were elucidated based on their spectral properties. All prenylflavanones demonstrated significant radical scavenging activity against diphenylpicrylhydrazyl radicals, and compound 6 showed significant antibacterial activity against Staphylococcus aureus. For the first time Macaranga tanarius L. and Mangifera indica L. are shown as plant sources of Indonesian propolis.

SOOM: Scalable Object-Oriented Middleware for Cooperative and Pervasive Computings

In the age of pervasive computing, ubiquitous collaboration has become an every-day life paradigm. Without an ideal computing infrastructure, issues with ubiquitous collaboration, such as network unreliability, platform heterogeneity, and client's resource constraints, are inevitable. The traditional replication scheme copes with network unreliability by replicating all the objects of a shared application together at once. This is, however, suitable for neither cooperative applications nor mobile computing devices. These problems can be naturally addressed by using a fine-grained replication scheme that enables a portion of the application objects to be replicated. This paper presents an object-oriented middleware that is capable of dynamically and transparently replicating remotely shared Java applications in a partially and on-demand incremental manner. It is also able to maintain various consistency semantics and enables the coexistence of fine-grained replications and conventional remote method invocations. Empirical results indicate several practical benefits of the middleware.
Cognitive ability in early adulthood and risk of 5 specific psychiatric disorders in middle age: the Vietnam experience study.

CONTEXT Lower cognitive ability is a risk factor for some forms of psychopathology, but much of the evidence for risk is based on individuals who required specialist care. It is unclear whether lower ability influences the risk of particular patterns of comorbidity. OBJECTIVE To examine the relation between premorbid cognitive ability in early adulthood and the risk of major depression, generalized anxiety disorder (GAD), posttraumatic stress disorder (PTSD), alcohol and other drug abuse or dependence, and comorbid forms of these conditions in midlife. DESIGN Prospective cohort study in which cognitive ability was measured on enlistment into military service at a mean age of 20.4 years and psychiatric disorder was assessed by structured diagnostic interview at a mean age of 38.3 years. SETTING The United States. PARTICIPANTS A total of 3258 male veterans, participants in the Vietnam Experience Study. MAIN OUTCOME MEASURES Major depression, GAD, PTSD, and alcohol or other drug abuse or dependence since enlistment and currently, diagnosed according to the DSM-III. RESULTS Lower cognitive ability was associated with an increased risk of depression, GAD, alcohol abuse or dependence, and PTSD and with some patterns of comorbidity. For a 1-SD decrease in cognitive ability, unadjusted odds ratios (95% confidence interval) for having these disorders currently were 1.32 (1.12-1.56) for depression, 1.43 (1.27-1.64) for GAD, 1.20 (1.08-1.35) for alcohol abuse or dependence, 1.39 (1.18-1.67) for PTSD, 2.50 (1.41-4.55) for PTSD plus GAD, 2.17 (1.47-3.22) for PTSD plus GAD plus depression, and 2.77 (1.12-6.66) for all 4 disorders. Most associations remained statistically significant after adjustment for confounders. CONCLUSIONS Lower cognitive ability is a risk factor for several specific psychiatric disorders, including some forms of comorbidity. Understanding the mechanisms whereby ability is linked to individual patterns of psychopathology may inform intervention.
Direct connection between perirhinal cortex and hippocampus is a major constituent of the lateral perforant path

Single‐pulse stimulation of the perirhinal cortex (PRC) evoked field responses in the dorsal hippocampal CA1 region in urethane‐anesthetized rats. In depth profiles conducted by moving the PRC stimulating electrode, the largest amplitude hippocampal potential was generated when the stimulating electrode was located within the perirhinal region. More dorsal (temporal cortex) or more ventral (lateral entorhinal cortex) stimulating sites elicited minimal hippocampal potentials. The hippocampal response was maintained during 100 Hz stimulation of the PRC, suggesting that it was monosynaptic, and high‐frequency stimulation (400 Hz) of the PRC produced a significant potentiation of hippocampal CA1 field potentials (46.73 ± 4.14%). When the PRC and the lateral perforant path (LPP) were stimulated separately, the depth/amplitude profiles obtained from a roving recording electrode located within the dorsal hippocampus were similar. In order to determine if fibers from PRC project to the hippocampus via the LPP, the PRC‐CA1 and LPP‐CA1 potentials were recorded prior to and during procaine (20%, 0.5 μl) blockade of the LPP. A simultaneous loss of both potentials was observed immediately following procaine infusion, while a commissural control potential was unaffected. Both LPP and PRC potentials returned approximately 30–40 min later. Electrolytic lesions of PRC produced a significant decrease in the amplitude of LPP‐hippocampal potentials when testing was conducted 4–5 days postlesion. Lesions of lateral entorhinal cortex or temporal cortex did not produce such effects. These data suggest that a direct pathway from perirhinal cortex to the dorsal hippocampal CA1 field can undergo long‐term potentiation (LTP) and that this pathway makes a major contribution to the lateral perforant path. © 1996 Wiley‐Liss, Inc.
Discovery of Cellulose as a Smart Material

The past 10 years has witnessed a renewed interest in cellulose research and application, sparked mostly by technological interests in renewable raw materials and more environmentally friendly and sustainable resources. In this paper, we further expand the current knowledge in cellulose applications and technologies by reporting our discovery of cellulose as a smart material that can be used for biomimetic sensor/actuator devices and micro-electromechanical systems. This smart cellulose is termed electroactive paper (EAPap). It can produce a large bending displacement with low actuation voltage and low power consumption. The actuation phenomenon and its characteristics are illustrated in this paper. Because cellulose EAPap is ultra-lightweight, inexpensive, and biodegradable, it is advantageous for many applications such as micro-insect robots, micro-flying objects, micro-electromechanical systems, biosensors, and flexible electrical displays.
