The Interaction between Radio Lobes and Hot Gas in the Nearby Radio Galaxies 3C 285 and 3C 442A

We present Chandra observations of two nearby radio galaxies in group environments, 3C 285 and 3C 442A. The host galaxies of both sources are involved in mergers with nearby massive galaxies, and the hot gas in the systems is extended along lines joining the interacting galaxies. Both sources show strong evidence for interactions between the radio lobes and the asymmetrical hot gas. We argue that the structure in the hot gas is independent of the existence of the radio lobes in these systems and further that hot gas shaped by an ongoing massive galaxy merger may play an important role in the dynamics of radio lobes in other objects. For 3C 442A, our observations show that gas is being driven out of both members of the host interacting galaxy pair, and the implied constraints on galaxy velocities are consistent with mildly supersonic motions with respect to the group-scale hot gas. The previously known filamentary radio structure in the center of 3C 442A may be a result of the interaction between hot gas expelled from these galaxies and preexisting radio-emitting plasma. In 3C 285, where there is no ongoing galaxy merger, the powerful radio source is probably having a significant effect on the energetics of the host group.
Competing Information and Attention Allocation: Evidence from China

This paper investigate the investor attraction hypothesis by examining how the number of earnings by other firms affects the sensitivity of a firm's announcement-period return, and post-event return reaction to its earnings surprise. The evidence indicates that the immediate stock price reaction to a firm's earnings surprise is weaker, and post-earnings announcement drift is weaker, when a greater number of earnings announcements by other firms are made on the same day. These findings generally support the investor attraction hypothesis.

Content-Based Image Retrieval using moments of wavelet transform

With the rapid production of huge amount of digital images, it has become extremely essential to develop efficient systems to organize and index images for easy access. Content-Based Image Retrieval (CBIR) is one such system which solves this problem. This paper proposes an image retrieval technique based on moments of wavelet transform. Discrete wavelet transform (DWT) coefficients of grayscale images are computed which are then normalized using z-score normalization. Geometric moments of these normalized coefficients are computed to construct feature vectors. These feature vectors are used to retrieve visually similar images from large database. Performance of the proposed method is tested on Corel-1000 database and measured using precision and recall parameters. The experimental results show that the proposed method outperforms some of the other state-of-the-art methods in terms of precision and recall.
A NOTE ON THE UNITARITY PROPERTY OF THE GASSNER INVARIANT

The unitarity of the Gassner representation [1] of the pure braid group was discussed by many authors (e. g. [2; 3; 4]) and from several points of view, yet without exposing how utterly simple the formulas turn out to be. Partially this is because the formulas are simplest when extended a “Gassner invariant” defined on the full braid group, but then it is not a rep -resentation and it is not unitary. Yet it has an easy “unitarity property”; see below. When the present author needed quick and easy formulas, he couldn’t find them. This note is written in order to rectify this situation (but with no discussion of theory). I was heavily influenced by a similar discussion of the unitarity of the Burau representation in [5. Section 3.1. 2]. Let
Revisiting Software Zero-Copy for Web-caching Applications with Twin Memory Allocation

A key concern with zero copy is that the data to be sent out might be mutated by applications. In this paper, focusing specially on web-caching application, we observe that in most cases the data to be sent out is not supposed to be mutated by applications, while the metadata around it does get mutated. Based on this observation, we propose a lightweight software zero-copy mechanism that uses a twin memory allocator to allocate spaces for zero-copying data, and ensures such data is unchanged before being sent out with a lightweight data protection mechanism. The only change required to an application is to allocate zero-copying data through a specific ZCopy memory allocator. To demonstrate the effectiveness of ZCopy, we have designed and implemented a prototype based on Linux and ported two applications with very little effort. Experiments with Memcached and Varnish shows that show that ZCopy can achieve up to 41% performance improvement over the vanilla Linux with less CPU consumption.
Spindle and kinetochore morphology of Dictyostelium discoideum

The metaphase spindle of haploid Dictyostelium discoideum (n = 7) is 2 mum long. It consists of some 20 microtubules which seem continuous between the spindle pole bodies and there are about 20 chromosomal microtubules at each end of the spindle. During anaphase the central spindle elongates and the chromosomal microtubules shorten. The spindle length and structure at this stage suggests that lengthening is caused by elongation as well as parallel sliding of the nonchromosomal microtubules. The nuclear envelope remains mostly intact during mitosis, and nuclear separation through medial constriction takes place when the spindle is 6 mum long. Cytokinesis occurs when the spindle is 10 mum long. At that time the kinetochores double in size. During interphase, the spindle pole body separates from the nucleus to a distance of 0.7 mum, and it returns at the onset of the next prophase when it becomes functionally double, thereby starting the formation of a central spindle. When comparing mitosis in the cellular slime molds Polysphondylium violaceum and D. discoideum, several similarities and some differences are apparent.
Farm Work, Off-Farm Work, And Hired Farm Labor: Estimating A Discrete-Choice Model Of French Farm Couples' Labor Decisions

We estimate jointly three types of discrete-choice labor decisions of farm couples: farm work, off-farm work, and hired farm labor. Using a 16-choice multinomial logit model, we find that operators' and spouses' farm labor are substitutes. Hired farm labor increases with farmers' qualifications, perhaps substituting for the couples' labor inputs. Other adults in the households substitute for the farm labor input of the farm couple and hired workers.
Systematic review of the impact of sacral neuromodulation on clinical symptoms and gastrointestinal physiology

Sacral neuromodulation (SNM) has emerged as a treatment option for faecal incontinence (FI). However, its objective effect on symptoms and anorectal function is inconsistently described. This study aimed to systematically review the impact of SNM on clinical symptoms and gastrointestinal physiology in patients with FI, including factors that may predict treatment outcome.
Photonic generation of microwave signal using a dual-wavelength single-longitudinal-mode fiber ring laser

A novel approach for the generation of high-frequency microwave signals using a dual-wavelength single-longitudinal-mode fiber ring laser is proposed and demonstrated. In the proposed configuration, a dual-wavelength fiber Bragg grating (FBG) with two ultranarrow transmission bands in combination with a regular FBG is used to ensure single-longitudinal-mode operation of the fiber ring laser. A semiconductor optical amplifier is employed as the gain medium in the ring cavity. Since the two lasing wavelengths share the same gain cavity, the relative phase fluctuations between the two wavelengths are low and can be used to generate a low-phase-noise microwave signal without need of a microwave reference source. Three dual-wavelength ultranarrow transmission-band FBGs with wavelength spacing of 0.148, 0.33, and 0.053 nm are respectively incorporated into the laser. Microwave signals at 18.68, 40.95, and 6.95 GHz are obtained by beating the dual wavelengths at a photodetector. The spectral width of the generated microwave signals as small as 80 kHz with a frequency stability better than 1 MHz in the free-running mode at room temperature is obtained.
Immunohistochemical Analysis of Cerebella in Mice With Conditional Depletion of IKKβ in the Microglia

Spinocerebellar Ataxia Type-1 (SCA-1) is an inherited neurodegenerative of the cerebellum caused by a mutant CAG polyglutamine repeat tract in the portion of the Sca1 gene that codes for the protein Ataxin-1. SCA-1 is frequently studied in mouse models. In almost any case of neurological injury, hypertrophy and proliferation of glial cells, called gliosis, is observed. Gliosis has potentially harmful effects on the pathology of neurological degeneration. In order to the effect of cytokine-mediated gliosis on SCA-1 mice, Lys-M-Cre IKKβ Flox transgenic mice were created. These mice have conditional depletion of IKKβ in the cerebellar microglia, IKKβ is an enzyme necessary for NF-κB mediated cytokine production, and without it, cells do not produce pro-inflammatory cytokines. We examined the cerebella of Lys-M-Cre IKKβ Flox mice through immunohistochemical staining, using microglia-specific marker IBA-1, astrocyte-specific markers GFAP and S-100, and Purkinje neuron-specific Calbindin. From IBA1 analysis, we have found that the loss of IKKβ does not cause microglial activation. Calbindin analysis revealed that the cerebella of Lys-M-Cre IKKβ Flox mice are morphologically similar and comparable to those that express IKKβ. GFAP and S-100 analysis demonstrated results in the astrocytes opposite of IKKβ depletion in microglia, which merits further analysis.
Characterization of SPECpower_ssj2008** benchmark

SPEC** recently released SPECpower_ssj2008, the first industry benchmark to measure performance and power of volume server class computers using graduated load levels. In this paper, we present a brief overview and an initial characterization of SPECpower_ssj2008 by measuring the utilization of system resources with the aid of processor monitoring events, at graduated load levels and by comparing the sensitivity of final metric and other related data between various configurations consisting of hardware changes as well as software changes on Intel Xeon processor based servers. Even though this is early data is from a specific platform and operating system, it does validate many expected behaviors and patterns opening exciting new opportunities for researchers to investigate specific areas as well as in-depth characterization as a next step.
Emergence of clinical Klebsiella pneumoniae producing OXA-232 carbapenemase in Singapore

We report the emergence of OXA-232, a newly described OXA-48-like carbapenemase variant, in Southeast Asia. Molecular characterization of eight Klebsiella pneumoniae obtained from local and foreign patients reveals clonality of the isolates. blaOXA-232 was located on a non-conjugative plasmid of 6141 base pairs (GenBank accession number JX423831.1).
EMDOR: Emergency message dissemination with ACK-overhearing based retransmission

In vehicular ad hoc networks (VANETs), providing drivers with safety service such as the reliable delivery of an emergency message is a challenge. To propagate the emergency message quickly to all vehicles, the broadcasting technique can be utilized, however, the broadcasting is vulnerable to unreliability. In this paper, we therefore propose a scheme to improve the broadcast reliability by allowing nodes to overhear an ACK message. A selected node transmits an ACK message on behalf of other receiving nodes. If a node overhears an ACK message, but has not received the corresponding message, the node considers that the emergency message is lost and requests the selected node to rebroadcast the emergency message. Using ns-2 simulator, we verify that our proposed scheme provides more reliable service than other existing solutions.
Industrial Hemp in North America: Production, Politics and Potential

Most of the Western World banned the cultivation of Cannabis sativa in the early 20th century because biotypes high in ∆9-tetrahydrocannabinol (THC, the principal intoxicant cannabinoid) are the source of marijuana. Nevertheless, since 1990, dozens of countries have authorized the licensed growth and processing of “industrial hemp” (cultivars with quite low levels of THC). Canada has concentrated on hemp oilseed production, and very recently, Europe changed its emphasis from fiber to oilseed. The USA, historically a major hemp producer, appears on the verge of reintroducing industrial hemp production. This presentation provides updates on various agricultural, scientific, social, and political considerations that impact the commercial hemp industry in the United States and Canada. The most promising scenario for the hemp industry in North America is a continuing focus on oilseed production, as well as cannabidiol (CBD), the principal non-intoxicant cannabinoid considered by many to have substantial medical potential, and currently in great demand as a pharmaceutical. Future success of the industrial hemp industry in North America is heavily dependent on the breeding of more productive oilseed cultivars, the continued development of consumer goods, reasonable but not overly restrictive regulations, and discouragement of overproduction associated with unrealistic enthusiasm. Changing attitudes have generated an unprecedented demand for the cannabis plant and its products, resulting in urgent needs for new legislative, regulatory, and business frameworks, as well as scientific, technological, and agricultural research.
Different Risk Adjusted Performance Measures for Equity Mutual Funds: A Comparative Study of VAR and Traditional Measures

Traditional measures of performance evaluation are in vogue since long, however, Value at Risk (VaR) approaches are making their place in portfolio management industry from the last ten years. Value at Risk (VaR) approach focuses on the downside volatility of portfolio, thus making the investor clear about the maximum possible loss on his portfolio. In today‘s highly volatile environment, an investor is concerned more about the downside risk rather upward swing in the portfolio. He would hesitate to invest in a portfolio having more downward risk. Present paper makes an attempt to compare both the traditional and VaR performance measures and explore whether differences exist in ranking of funds using both the approaches. Results indicated that Sharpe ratio and Normal VaR results are same when used independently, while there is difference in results using Treynor and Jensen‘s Alpha.
Design and Analysis of a 512768 Current-mediated Active Pixel Array Image Sensor

Current-mediated, current-output active pixels ooer the advantages of compact size and simple operation in designing large format CMOS image sensors, with performance limited by spatial xed pattern noise. In this paper, a thorough noise analysis is made of the expected performance of a current-output pixel image sensor. This analysis is compared with experimental results from a 512768 array imager fabricated in a 0:7m process, and the eeectiveness of basic error correction techniques are explored. The goal of this study was to determine the performance limits of this device and to gain insight into the design issues needed to develop a high quality current-output imager.
Evaluation scheme RFID channel in library with wooden and metal book shelves based on measurement data

At the present time, radio frequency identification (RFID) library management system are applied in many libraries for convenience and more efficiency. Channel modeling is necessary for predicting received power and performance system. In this paper, the channel of wooden and metal book shelves are modeled for RFID library management system. The channels were measured at frequency of 2.45 GHz. The microstrip antennas were used as both transmitter (Tx) and receiver (Rx) antennas. Vertical-vertical (V-V) and horizontal-horizontal (H-H) polarizations are considered. Linear regression is used to model the path loss characteristic. After that, statistical models, cumulative distribution function (CDF), are used to characterize the multipath fading. From the results, we can conclude that the wooden book shelves of V-V polarization and metal book shelves of H-H polarization are appropriate to use for RFID library management system.
AN INVESTIGATION INTO THE MACHINING CHARACTERISTICS OF NIMONIC 80A USING CNC WIRE- EDM

Wire Electrical Discharge machining process is extensively used in industry to manufacture geometrically complex, hard material parts that are extremely difficult to machine by conventional machining process. The present work investigates the influence of machining parameters on cutting speed and material removal rate for machining of Nimonic 80A with brass wire as tool electrode during wire electrical discharge machining process. Investigation indicated that cutting speed (CS) and material removal rate (MRR), both increases with increase in pulse-on-time (T on ) and peak current(IP), while decreases with increase in pulse-off-time (T off ) and spark gap set voltage (SV).
Pairing and superfluid properties of dilute fermion gases at unitarity

We study the system of a dilute gas of fermions in three dimensions, with attractive interactions tuned to the unitarity point, using the nonperturbative restricted path-integral Monte Carlo method. The pairing and superfluid properties of this system are calculated at finite temperature. The total energy at very low temperature from our results agrees closely with that of previous ground-state quantum Monte Carlo calculations. We identify the temperature T*{approx_equal}0.70{epsilon}{sub F}, below which pairing correlations develop, and estimate the critical temperature for the superfluid transition T{sub c}{approx_equal}0.245{epsilon}{sub F} from a finite size scaling analysis of the superfluid density.
An utility-based network selection scheme for future urban road wireless networks

Making an efficient, considerate and dynamic selection in heterogeneous wireless networks becomes a big challenge today. The traditional network selection based on utility function only considers two factors and destines to has limited use in multimedia application circumstances. In this paper, a novel utility based scheme is proposed to work in the future urban road heterogeneous wireless networks. The proposed scheme takes more key factors which are crucial for multimedia communication into account within a simple framework. Detailed design process is addressed.
Memory servers for multicomputers

A virtual memory management technique for multicomputers called memory servers is investigated. The memory server model extends the memory hierarchy of multicomputers by introducing a remote memory server layer. Memory servers are multicomputer nodes whose memory is used for fast backing storage and logically lie between the local physical memory and disks. The authors present the model, describe how the model supports sequential programs, message-passing programs, and shared virtual memory systems, discuss several design issues, and show preliminary results of a prototype implementation on an Intel iPSC/860. <<ETX>>
STATISTICAL MODELING FOR MOTION-BASED VIDEO CLASSIFICATION AND RETRIEVAL

We have developed an original approach for content-based video indexing and retrieval. By introducing a causal Gibbsian modeling of the spatio-temporal distribution of appropriate local motion-related measurements, we have designed a general and efficient statistical framework for non parametric motion modeling, motion recognition and classification, and motion segmentation. It is exploited for motionbased video indexing and video retrieval for both global and partial queries by example.
Exploiting natural dynamics in robot controlMatthew

This paper presents an approach to robot arm control based on exploiting the dynam-ical properties of an adaptive oscillator circuit coupled to the joints of an arm. The approach is implemented on a real robot arm, and swings pendulums at their natural frequencies, turns cranks and manipulates slinky toys. These actions are all achieved using the same architecture, without any modeling of the arm or its environment. The simple nature of the oscillators, and the lack of modeling results in a robust and very simple system.
Optimal Resource Allocation of Orthogonal Relay-Eavesdropper Channel

The orthogonal relay-eavesdropper channel is investigated. The source communicates with the relay and the destination in channel 1, the relay communicates with the destination in channel 2, channel 1 and channel 2 are orthogonal with each other. The secrecy rate is derived based on the analysis of parallel relay- eavesdropper channel. Under the limit of the total channel resource, the maximal secrecy rate is obtained through optimizing the resource allocation parameter a. In the Gaussian channel, when eavesdropper listen the signals of channel 1, it is proved that there exists the unique a to reach the maximum secrecy rate and a higher secrecy rate can be achieved using the optimal resource allocation strategy than the equal resource allocation strategy.
Rapid Detection of SNP (c.309T>G) in the MDM2 Gene by the Duplex SmartAmp Method

Background Genetic polymorphisms in the human MDM2 gene are suggested to be a tumor susceptibility marker and a prognostic factor for cancer. It has been reported that a single nucleotide polymorphism (SNP) c.309T>G in the MDM2 gene attenuates the tumor suppressor activity of p53 and accelerates tumor formation in humans. Methodology In this study, to detect the SNP c.309T>G in the MDM2 gene, we have developed a new SNP detection method, named “Duplex SmartAmp,” which enabled us to simultaneously detect both 309T and 309G alleles in one tube. To develop this new method, we introduced new primers i.e., nBP and oBPs, as well as two different fluorescent dyes that separately detect those genetic polymorphisms. Results and Conclusions By the Duplex SmartAmp method, the genetic polymorphisms of the MDM2 gene were detected directly from a small amount of genomic DNA or blood samples. We used 96 genomic DNA and 24 blood samples to validate the Duplex SmartAmp by comparison with results of the conventional PCR-RFLP method; consequently, the Duplex SmartAmp results agreed totally with those of the PCR-RFLP method. Thus, the new SNP detection method is considered useful for detecting the SNP c.309T>G in the MDM2 gene so as to judge cancer susceptibility against some cellular stress in the clinical setting, and also to handle a large number of samples and enable rapid clinical diagnosis.
