A new approach for terrorist attack vulnerability evaluation of power transmission lines

Power transmission systems are prone to several vulnerabilities which may result in deterioration of system stability and incapacities due to equipment contingencies. The causes leading to contingency and instability are ranging from natural disasters to malevolent acts as well as misoperations and equipment's hidden failures. In principle, most power systems are designed in an efficient manner in order to provide openness and accessibility for Transmission System Operator (TSO) personnel. As a result of this fact, the term power system vulnerability becomes directly related with the physical reach of either natural calamities or some terrorist acts. Thus, a measure for possible disruption events is needed in order to have a more generalized and comprehensive figure of vulnerability degree measurement required for analysis. In this study, a measure for power transmission line's terrorist attack vulnerability evaluation is presented using IEEE reliability test system with external constraints imposed on system data.
Helminth parasites of Thomomys bulbivorus (Richardson) (Rodentia: Geomyidae), with the description of a new species of Hymenolepis (Cestoda)

A cestode, Hymenolepis tualatinensis n. sp. , is described from the pocket gopher, Thomomys bulbivorus (Richardson) (Rodentia: Geomyidae), from the Willamette Valley in Oregon. Helminths of four additional species were found. Trichuris fossor Hall, 1916, Ransomus rodentorum Hall, 1916, Heligmosomoides thomomyos Gardner and Jasmer, 1983, and Hymenolepis horrida (von Linstow, 1901), of which all but H. thomomyos represent new host records. A significant change in prevalence of the whipworm T. fossor in the population of T. bulbivorus from spring through summer was noted. Significant differences in prevalence of infection of helminths in pocket gophers collected from two different localities in the Willamette Valley were observed.
The Design of Bi-CMOS LVDS Output Buffer with ESD Protection Circuit Using 90nm CMOS Technology

This paper presents the design of novel LVDS (Low-Voltage-Differential-Signaling) output buffer for Gb/sper-pin operation using 90 nm CMOS technology. The proposed LVDS driver is designed to reduce chip area, using a novel bipolar transistor switch. The proposed LVDS transmitter is operated at 1.8 V low-power supply. Its maximum data rate is 2.8 Gb/s approximately. Also, the new structural ESD (Electro-Static Discharge) protection device is designed to improve the proposed LVDS driver's ESD protection performance. The proposed device can reduce latch-up phenomenon in normal operating condition. In the measurement result, the proposed ESD clamp has trigger voltage of 3.7 V and holding voltage of 2.3 V. The robustness of the LVDS driver with proposed ESD protection has measured to about 2kV (IEC61000-4-2).
A Neural Microcircuit Model for a Scalable Scale-invariant Representation of Time

Scale-invariant timing has been observed in a wide range of behavioral experiments. The firing properties of recently described time cells provide a possible neural substrate for scale-invariant behavior. Earlier neural circuit models do not produce scale-invariant neural sequences. In this paper we present a biologically detailed network model based on an earlier mathematical algorithm. The simulations incorporate exponentially decaying persistent firing maintained by the calcium-activated nonspecific (CAN) cationic current and a network structure given by the inverse Laplace transform to generate time cells with scale-invariant firing rates. This model provides the first biologically detailed neural circuit for generating scale-invariant time cells. The circuit that implements the inverse Laplace transform merely consists of off-center/on-surround receptive fields. Critically, rescaling temporal sequences can be accomplished simply via cortical gain control (changing the slope of the f-I curve).
Managing the geographically distributed datacenters

In the field of Big Data analytics the steps taken to collect and analyze the large amount of data to get useful information is the major use of cloud services today. Traditionally the large volume of data was gathered, stored and analyzed in only one data center. As the volume of data has started increasing at a tremendous rate, using the single data centers will lead to improper and less efficient handling of data from the point of performance, where the single data center cannot handle the huge volume of datasets. So, for the better performance and availability, deploying the multiple data centers around the world geographically by the large cloud services providers can resolve this challenge [9]. There are many approaches but widely used approach for the analytics of the geographical distributed data is the centralized approaches. In centralized approach, the data is gathered and stored locally in the main datacenter but this approach may leads to worse performance because this approach may consume a significant amount of bandwidth. To achieve the optimal performance numbers of mechanisms have been used where the data analytics has been performed over the geo-distributed data center.
Torus nano-antenna: Enhanced field and radiation pattern

This work presents numerical investigations for the performance of a torus nano-antenna using the method of moments. Plane waves of parallel and perpendicular polarizations, with respect to the plane of the torus, are used in excitation. Two noble metals, gold and silver, are considered in this work. The resonance, the enhanced near-field, and the far-field radiation of the torus nano-antenna are studied.
First direct archosauromorph remains from the Early-Middle Triassic transition of the Iberian Peninsula

This paper discusses the taxonomic affinities of three isolated teeth discovered in the Buntsandstein facies of the Catalan Coastal Ranges and central-eastern Pyrenean basins that crop out in Catalonia, north-eastern Spain. The tooth crowns are blade-like, labiolingually compressed, distally recurved, and proportionally apicobasally tall, in which the most complete of them is at least 2.4 times taller than its mesiodistal depth at base. The distal margins possess a densely serrated carina, and the mesial margins lack carina and serrations. The enamel of the crowns lacks ornamentation (e.g., wrinkles, ridges) or macroscopic wear-facets. The three teeth are referred to indeterminate crocopodan archosauromorphs based on the presence of labiolingually compressed and serrated crowns. The absence of mesial denticles resembles the condition in the non-archosauriform archosauromorph Teyujagua, proterosuchids, and some more crownward archosauriforms (e.g., some proterochampsids). We could not find evidence to determine if these teeth belong to a single or multiple closely related species. These remains represent the first direct archosauromorph remains from Lower−Middle Triassic beds of the Iberian Peninsula and add information about the geographic distribution of the group during the dawn of the evolutionary radiation of the group.

Low-power null convention logic design based on modified gate diffusion input technique

Null Convention Logic (NCL) is the one of the well-known clock-less approaches for designing asynchronous logic circuits. The complementary metal oxide semiconductor (CMOS) technology is usually used for implementing the NCL circuits, which as a major drawback of large area consumption and power dissipation. These limitations have been addressed by adopting a low-power design technique called Gate Diffusion Input (GDI) in this work. GDI technique allows implementing primitive logic gates using only two transistors. Thus, it not only reduces the transistor count but also the power consumption. However, GDI technique suffers a significant voltage drop across the circuit, due to its inherent voltage swings. Thus, to ensure full swing output regenerative buffers are added at the output stage which tends to increase the overall latency. In this work, a novel GDI and HYBRID (CMOS+GDI) designs are proposed to overcome the limitations of the CMOS-NCL designs. The proposed approaches were tested by realizing NCL Ripple Carry Adder (RCA). The proposed model was simulated in Cadence Virtuoso and power reduction of 14.9 % and 9.8 % has been observedfor GDI and HYBRID models, respectively.
Modulation of K 1 channels by arachidonic acid in T 84 cells . II . Activation of a Ca 2 1-independent K 1 channel

Devor, Daniel C. , and Raymond A. Frizzell. Modulation of K1 channels by arachidonic acid in T84 cells. II. Activation of a Ca21-independent K1 channel. Am. J. Physiol. 274 (Cell Physiol. 43): C149–C160, 1998. —We used singlechannel recording techniques to identify and characterize a large-conductance, Ca21-independent K1 channel in the colonic secretory cell line T84. In symmetric potassium gluconate, this channel had a linear current-voltage relationship with a single-channel conductance of 161 pS. Channel open probability (Po) was increased at depolarizing potentials. Partial substitution of bath K1 with Na1 indicated a permeability ratio of K1 to Na1 of 25:1. Channel Po was reduced by extracellular Ba21. Event-duration analysis suggested a linear kinetic model for channel gating having a single open state and three closed states: C3;=C2;=C1;=O. Arachidonic acid (AA) increased the Po of the channel, with an apparent stimulatory constant (Ks) of 1.39 μM. Neither channel open time (O) nor the fast closed time (C1) was affected by AA. In contrast, AA dramatically reduced mean closed time by decreasing both C3 and C2. The cis-unsaturated fatty acid linoleate increased Po also, whereas the saturated fatty acid myristate and the trans-unsaturated fatty acid elaidate did not affect Po. This channel is activated also by negative pressure applied to the pipette during inside-out recording. Thus we determined the effect of the stretch-activated channel blockers amiloride and Gd31 on the K1 channel after activation by AA. Amiloride (2 mM) on the extracellular side reduced single-channel amplitude in a voltage-dependent manner, whereas Gd31 (100 μM) had no effect on channel activity. Activation of this K1 channel may be important during stimulation of Cl2 secretion by agonists that use AA as a second messenger (e.g., vasoactive intestinal polypeptide, adenosine) or during the volume regulatory response to cell swelling.
Study protocol 1 Design of the Primary Prevention Parameters Evaluation ( PREPARE ) trial of implantablecardioverter defibrillators to reduce patient morbidity [ NCT 00279279 ]

Background: Implantable Cardioverter Defibrillator (ICD) therapy has been proven to be beneficial and efficacious for the treatment of serious ventricular tachyarrhythmias in primary prevention patients. However, primary prevention patients appear to have a lower incidence of ventricular arrhythmias in comparison to secondary prevention patients and consequently likely experience a higher proportion of detections due to supraventricular arrhythmias. Recent trials have demonstrated that strategic and specific programming choices reduce the number of inappropriate shocks and that anti-tachycardia pacing (ATP) is an effective alternative to shock therapy for many sustained ventricular arrhythmias. Methods: The Primary Prevention Parameters Evaluation (PREPARE) study is a multi-center cohort study, evaluating the efficacy of a pre-specified strategic profile of VT/VF detection and therapy settings in 700 primary prevention patients in an effort to safely reduce the number of shock therapies delivered. The patients, both with and without cardiac resynchronization therapy, are compared to a well-qualified set (n = 691) of historical controls derived from the MIRACLE ICD and EMPIRIC trials. This manuscript describes the design of the PREPARE study. The study results, to be presented separately, will characterize the efficacy of this programming set (PREPARE) compared with physician-tailored programming (MIRACLE ICD and EMPIRIC). Background Implantable defibrillator therapy terminates ventricular tachyarrhythmias and improves survival of patients in multiple populations at risk of sudden cardiac death. [13] Initially, ICD therapy was applied only to secondary prevention patients: that is, those who had been resuscitated from a cardiac arrest or other sustained ventricular tachyarrhythmias. The impact of other studies, such as MADIT, MUSTT, MADIT II and SCD-HeFT, as well as the CMS national coverage decision in January of 2005, is that the large majority of patients currently receiving ICDs Published: 25 May 2006 Trials 2006, 7:18 doi:10.1186/1745-6215-7-18 Received: 03 May 2006 Accepted: 25 May 2006 This article is available from: http://www.trialsjournal. com/content/7/1/18 © 2006 Wilkoff et al; licensee BioMed Central Ltd.

A Visual Analytics Approach for Crime Signature Generation and Exploration

The exploration of volumes of crime reports is a tedious task in crime intelligence analysis, given the largely unstructured nature of the crime descriptions. This paper describes a Visual Analytics approach for crime signature exploration that tightly integrates automated event sequence extraction and signature mining with interactive visualization. We describe the major components of our analysis pipeline — crime concept/event extraction, crime sequence mining, and interactive visualization. We illustrate its applicability with a real world use case. Finally, we discuss current problems, future plans, and open challenges in our development of a solution that incorporates automated event pattern mining with human expert feedback.
Learning a robust DOA estimation model with acoustic vector sensor cues

Accurate and robust Direction of Arrival (DOA) estimation with small microphone arrays is gaining an increasing demand in service robotics and smart home applications. Classic non-learning DOA estimation methods show unsatisfactory performance under low SNR or high reverberation conditions. Meanwhile, some research outcomes illustrate that learning methods with Neural Networks (NN) ask for careful array element quantity or layout regulation which is impractical for many applications. In order to obtain robust DOA estimation with small arrays, taking the learning ability of Deep Neural Networks (DNN), we propose to form the training pairs by using Acoustic Vector Sensor - Direction of Arrival (AVS-DOA) cues and its counterpart DOA which can be simulated under different SNR and reverberation conditions. Then DNN-based DOA model is trained accordingly and the performance of the model has been fully investigated with different activation functions, network structures and dropout rates. With the cross-validation process, the model performing best experimentally is selected as the optimal DOA model. Experimental results validate the effectiveness of our DNN based DOA model which outperforms the non-learning method, especially under poor acoustic conditions.

A data-driven neuroendocrine-PID controller for underactuated systems based on safe experimentation dynamics

This paper presents a data-driven neuroendocrine-PID controller for underactuated systems. Safe Experimentation Dynamics (SED) is employed to find the optimum neuroendocrine-PID parameters such that the control tracking performance and input energy are minimized. The advantage of the proposed approach is that it can generate fast neuroendocrine-PID parameter tuning by measuring the input and output data of the system without using the plant mathematical model. Moreover, the combination of neuroendocrine structure with PID has a great potential in improving the control performance as compared to the PID controller. An underactuated container crane model is considered to validate the proposed data-driven design. In addition, the performance of the proposed method is investigated in terms of the trolley position, hoist rope length and sway angle trajectory tracking. The simulation results show that the data-driven neuroendocrine-PID approach provides better control performance as compared to the PID controller.
On the Origin of Amazonian Landscapes and Biodiversity: A Synthesis

In northern South America the Cenozoic was a period of intense tectonic and climatic interaction that resulted in a dynamic Amazonian landscape dominated by lowlands with local and shield-derived rivers. These drainage systems constantly changed shape and size. During the entire Cenozoic, the Brazilian and Guiana Shields were stable mountainous areas. Andean-derived river systems increased in importance especially in the Neogene. A remarkable feature in western Amazonian history is the waxing and waning of large lake systems and embayments. By the Late Miocene (about 11 Ma), the Andes were connected with the Atlantic through an incipient Amazon River, and from c. 7 Ma Andean-derived river systems became fully established in central and eastern Amazonia and the modern landscape configuration had developed. Rainforests already existed in northern South America during the Paleogene, but the modern rainforests - with resemblance to the Present forest - only developed during the Miocene. The western Amazonian Miocene record contains very diverse aquatic faunas (molluscs, ostracods, turtles, crocodiles, fishes) as well as terrestrial mammals. Remarkable gigantic forms thrived in Amazonian ecosystems at the time. Since the Late Miocene, edaphically heterogeneous lands emerged in western Amazonia in areas previously occupied by lake systems. At the same time nutrient-rich deposits spread over central and eastern Amazonia, an event that, based on molecular phylogenetic studies on extant taxa, coincided with diversification of terrestrial taxa. Molecular-based time estimates confirm the steady diversification and mostly pre-Quaternary origin of extant Amazonian taxa. A significant portion of the current species richness is attributed to a combination of relatively constant wet and warm climates and a heterogeneous edaphic substrate. The Quaternary was a time of distribution shifts, but can no longer be considered a time of diversification in Amazonia.
Effect of Dietary Zinc on Certain Blood Traits of Broiler Breeder Chickens

The aim of the present study was to evaluate the effect of zinc as feed additive on some the blood plasma traits of males and females of broiler breeder chickens. A total 132 (96 females and 36 males) of Cobb 500 broiler breeder chickens, 45 weeks old were used in this study. These birds were randomly distributed into four dietary treatment groups with three replicates each. Each treatment group constituted of 24 females and 9 males. Treatment groups were as following: T1: Birds fed the basal diet without any addition of zinc (0 Zn) (Control), T2: Birds fed diet supplemented with 50 mg Zn (pure zinc)/kg of diet, T3: Birds fed diet supplemented with 75 mg Zn (pure zinc)/kg of diet and T4: Birds fed diet supplemented with 100 mg Zn (pure zinc)/kg of diet. Results indicated that dietary zinc supplementation (T2, T3 and T4) resulted in significant (p<0.05) increase in blood plasma cholesterol, protein, calcium and phosphorus concentration and Alkaline Phosphatase (ALP) activity in broiler breeders males and females during 58 and 66 weeks of age and as regards the total means of these traits as compared with control group (T1). However, adding different levels of zinc to the diet (T2, T3 and T4) resulted in significant (p<0.05) increase in blood plasma glucose in broiler breeders males and females during 54, 58, 62 and 66 weeks of age and concerning the total mean of this trait. In conclusion, supplementing the diet of broiler breeder chickens with zinc caused significant increase in blood plasma traits included in this study. Therefore, zinc can be used as efficient feed additive for enhance physiological status of birds.
HIGH-SPEED IMAGING AND WAVEFRONT SENSING WITH AN INFRARED AVALANCHE PHOTODIODE ARRAY

Infrared avalanche photodiode (APD) arrays represent a panacea for many branches of astronomy by enabling extremely low-noise, high-speed, and even photon-counting measurements at near-infrared wavelengths. We recently demonstrated the use of an early engineering-grade infrared APD array that achieves a correlated double sampling read noise of 0.73 e− in the lab, and a total noise of 2.52 e− on sky, and supports simultaneous high-speed imaging and tip-tilt wavefront sensing with the Robo-AO visible-light laser adaptive optics (AO) system at the Palomar Observatory 1.5 m telescope. Here we report on the improved image quality simultaneously achieved at visible and infrared wavelengths by using the array as part of an image stabilization control loop with AO-sharpened guide stars. We also discuss a newly enabled survey of nearby late M-dwarf multiplicity, as well as future uses of this technology in other AO and high-contrast imaging applications.
Environmental Quality Regarding the Primary National Ambient Air Quality Standards for Ozone and PM , and the Utility MACT Main Conclusions

Main Conclusions On behalf of the Texas Commission on Environmental Quality (TCEQ), I disagree with the United States Environmental Protection Agency’s (EPA) proposed range of values for the eight-hour ozone and PM standards because of uncertainties relating ambient concentrations to personal exposures and limitations of the epidemiological and clinical studies used as the basis of the revisions. The TCEQ strongly recommends that EPA use robust scientific data as the basis for the ozone and PM standards and Utility MACT, and more meaningful consideration of risk management issues in its final policy decisions.
