A Improved EPC Class 1 Gen 2 Protocol with FCFS Feature in the Mobile RFID Systems

In all anti-collision protocols of RFID standards, EPCGlobal Class 1 Generation 2 (C1G2) protocol has been most widely used in RFID systems since it is simply, efficient and safety. Similar to most existing anti-collision protocols, The C1G2 protocol initially aims at tag identification of static scenarios, where all tags keep still during the tag identification process. However, in many real scenarios, tags generally move along a fixed path in the reader coverage area, which implies that tags stay the coverage area only for a limited time (sojourn time). The scenarios are usually called mobile RFID systems. Because the multiple tag identification based on a shared wireless channel is random, tags entering the reader coverage area earlier may be identified later (random later identification phenomenon). The phenomenon and the limited sojourn time may let some tags lost. In this paper, we propose an improved C1G2 protocol with first come first served feature in mobile RFID systems. The protocol can overcome the RLI phenomenon effectively and retains good initial qualities of C1G2 protocol by modifying it slightly. Simulation results show that the proposed protocol can significantly reduce the numbers of lost tags in mobile RFID systems. The idea of the paper is beneficial for redesigning other existing tag anti-collision protocols so as to make these protocols adapt to mobile RFID systems.
Strodl Emotional Eaters Cognitive Behavior Therapy and Dialectical Behavior Therapy for Treating Obese

This study describes the treatment of obese individuals who rated high on emotional eating using four case studies that involved 22 sessions of either cognitive behavioral therapy (CBT) or dialectical behavioral therapy (DBT). Outcomes measures relating to weight, body mass index, emotional eating, depression, anxiety, and stress were all assessed with each participant prior to each baseline (three weekly sessions), during treatment and posttherapy. At the 8-week follow-up, the two cases that had received DBT had lost 10.1% and 7.6% of their initial body weight, whereas the two cases that had received CBT had lost 0.7% and 0.6% of their initial body weight. The two DBT cases also exhibited reductions in emotional distress, frequency of emotional eating or quantity of food eating in response to emotions, whereas the two CBT cases showed no overall reductions in these areas. Important processes from all four cases are described as are the implications to clinicians for developing more effective interventions for obese clients who engage in emotional eating.
Environmental effects on star formation in dwarf galaxies and star clusters

We develop a simple analytical criterion to investigate the role of the environment on the onset of star formation. We will consider the main external agents that influence the star formation (i.e. ram pressure, tidal interaction, Rayleigh-Taylor and Kelvin-Helmholtz instabilities) in a spherical galaxy moving through an external environment. The theoretical framework developed here has direct applications to the cases of dwarf galaxies in galaxy clusters and dwarf galaxies orbiting our Milky Way system, as well as any primordial gas-rich cluster of stars orbiting within its host galaxy. We develop an analytic formalism to solve the fluid dynamics equations in a non-inertial reference frame mapped with spherical coordinates. The two-fluids instability at the interface between a stellar system and its surrounding hotter and less dense environment is related to the star formation processes through a set of differential equations. The solution presented here is quite general, allowing us to investigate most kinds of orbits allowed in a gravitationally bound system of stars in interaction with a major massive companion. We present an analytical criterion to elucidate the dependence of star formation in a spherical stellar system (as a dwarf galaxy or a globular cluster) on its surrounding environment useful in theoretical interpretations of numerical results as well as observational applications. We show how spherical coordinates naturally enlighten the interpretation of the two-fluids instability in a geometry that directly applies to astrophysical case. This criterion predicts the threshold value for the onset of star formation in a mass vs. size space for any orbit of interest. Moreover, we show for the first time the theoretical dependencies of the different instability phenomena acting on a system in a fully analytical way.

Recognition of intrusions and analysis of the dynamics of the violator's actions are implemented on the basis of a tree classifier and Kohonen maps for neural networks. The system includes agents for intrusion detection and state forecasting, takes into account the dynamics and stochastic uncertainty of the main information protection processes in information network, provides monitoring, intrusion detection and forecasting of the information security state in intellectual protection processes.
Intraseasonal variations of surface and subsurface currents off Java as simulated in a high‐resolution ocean general circulation model

[1] A high-resolution ocean general circulation model (OGCM) is used to explore dynamics of intraseasonal variability in surface and subsurface currents off Java. The results indicate that the surface current, the so-called South Java Coastal Current (SJCC), is dominated by variations with a period of 90 days. In the subsurface current, which is referred to as the South Java Coastal Undercurrent (SJCU), 60-day variations are the most prominent feature. A normal mode analysis demonstrates that the first baroclinic mode is the leading mode, which accounts for 70% of the total variance, whereas the second baroclinic mode explains 24% of the total variance. The 90-day variations in the SJCC captured mostly by the first baroclinic mode are found to be primarily driven by winds. Those are associated with propagation of the first baroclinic Kelvin waves generated in the central equatorial Indian Ocean. On the other hand, the 60-day variations in the SJCU enhanced by wind forcing over the eastern equatorial Indian Ocean off Sumatra are mostly captured by the second baroclinic mode.
“My Two Masters”: Conflict, Contestation, and Identity Construction Within a Teaching Practicum

This paper reports the results of a qualitative study into the teaching practice experiences of eight preservice English language teachers in Hong Kong. Using in-depth interviews, the preservice teachers' practicum experiences are explored in terms of their understandings of the requirements of their teacher education institution and their teaching placement school, their relations with full time teachers within their placement schools, as well as their own beliefs about the teaching and learning of the English language. A contribution of this study is to examine these experiences through the lens of teacher identity construction. Results indicated that participants constructed rigid divisions between different identity positions that they took on, resisted, and rejected during their teaching practice experiences, and that relations between these identity categories were often characterized by antagonism. It is argued that such antagonism may be detrimental to the preservice teachers during their practicum and as they move into full time teaching positions. How these divisions might be challenged is discussed and implications for future research are considered.
Profile of Transforming Growth Factor Beta 1 Gene (TGF- b1) Nucleotide 29 T869C Polymorphism in Malaysian Rheumatoid Arthritis patients

Introduction:Various studies on Rheumatoid arthritis (RA) patients suggested that polymorphism in the Transforming Growth Factor-Beta 1 (TGF- b1) gene may be associated with increased risk of RA severity. Results: Fifty-nine patients (52.68%%) were found to have non-severe disease and 53 patients (47.32%) were found to have severe disease. The frequency of CT genotype was the highest among the 3 genotypes (78 out of 112). For the Malays, 6 patients (12.5%) were CC genotype, 33 patients (68.7%) were CT genotype and 9 patients (18.8%) were TT genotype. For the Chinese, 7 patients (21.2%) were CC genotype, 22 patients (66.7%) were CT genotype and 4 patients (12.1%) were TT genotype. For the Indians, 5 patients (17.9%) were CC genotype, 20 patients (71.4%) were CT genotype and 3 patients (10.7%) were TT genotype. For the other ethnic groups, all 3 patients were CT genotype. Conclusion: CT genotype has the highest frequency (69.6%) Faculty of Medicine UKM Research Grant FF- 055- 2006

In this paper the newsvendor model and the newsvendor game will be introduced, followed by a brief review of the literature on the topic. Some basic concepts of cooperative game theory and allocation methods are going to be explained and after the newsvendor game model will be explored, MATLAB will be used to compute the Shapley value in the game. The results will then be analyzed, with different levels of correlations and cost that will help to draw conclusions.
Retrieval of O 2 ( 1 Σ) and O 2 ( 1 Δ) volume emission rates in the mesosphere and lower thermosphere using SCIAMACHY MLT limb scans

Abstract. We present the retrieved volume emission rates (VERs) from the airglow of both the daytime and twilight O2(1Σ) band and O2(1Δ) band emissions in the mesosphere and lower thermosphere (MLT). The SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY (SCIAMACHY) onboard the European Space Agency Envisat satellite observes upwelling radiances in limb-viewing geometry during its special MLT mode over the range 50–150 km. In this study we use the limb observations in the visible (595–811 nm) and near-infrared (1200–1360 nm) bands. We have investigated the daily mean latitudinal distributions and the time series of the retrieved VER in the altitude range from 53 to 149 km. The maximal observed VERs of O2(1Δ) during daytime are typically 1 to 2 orders of magnitude larger than those of O2(1Σ). The latter peaks at around 90 km, whereas the O2(1Δ) emissivity decreases with altitude, with the largest values at the lower edge of the observations (about 53 km). The VER values in the upper mesosphere (above 80 km) are found to depend on the position of the sun, with pronounced high values occurring during summer for O2(1Δ). O2(1Σ) emissions show additional high values at polar latitudes during winter and spring. These additional high values are presumably related to the downwelling of atomic oxygen after large sudden stratospheric warmings (SSWs). Accurate measurements of the O2(1Σ) and O2(1Δ) airglow, provided that the mechanism of their production is understood, yield valuable information about both the chemistry and dynamics in the MLT. For example, they can be used to infer the amounts and distribution of ozone, solar heating rates, and temperature in the MLT.
Characterisation and undrained strength of amorphous clay

This paper presents the physiochemical properties and relationship of saturated remoulded undrained shear strength, sur, against water content, w, for an amorphous organic clay, namely an alum water-treatment residue material derived from the production of potable water. The log w–log sur relationship was found to be strongly linear, and extended well beyond the measured plastic range. The effects of microstructure, and the shearing modes, rates and specimen confinement, are reported, along with the correspondence between sur measured in triaxial compression and that deduced from fall-cone and miniature vane tests. The mobilised strength exhibited high strain-rate dependence, increasing by ∼30%/log e˙ cycle increase. The bulk water-treatment residue material could be easily remoulded at water contents below the measured Casagrande plastic limit, indicating that the reported plastic range was notional and, furthermore, that the use of liquidity index as an indicator of the material's consistency is unrelia.
Application of Markov chain Monte carlo method in Bayesian statistics

In statistical inference methods, bayesian method is a method of great influence. This paper introduces the basic idea of the bayesian method. However, the widespread popularity of MCMC samplers is largely due to their impact on solving statistical computation problems related to Bayesian inference. Markov chain Monte Carlo method is essentially a Monte Carlo synthesis procedure. The random sample of it is related to a Markov chain. It is a widely used stochastic simulation method. This paper mainly introduces Gibbs sampling, and its application in Bayesian statistics. We use a simple example to illustrate how to tackle a typical Bayesian problem via the MCMC method
Evaluating the effect of active edible coating of quince seed mucilage and green tea extract on the quality of fried shrimps: physicochemical and sensory properties

Background and Objectives: In recent years, to reduce the adverse effects of fried products, various techniques have been suggested for reduction of oil uptake in fried product. The use of edible coating is one of the most important technologies proposed. In the study, the effect of bioactive coating composed of quince seed mucilage (QSM) and incorporating green tea extract (GTE) on the physicochemical quality of shrimp after deep-fat frying were investigated. Materials and Methods: In this study, active edible coating using quince seed mucilage and adding different concentration of GTE (0-20%) was prepared. The effects of five coating solutions (QG 0-4) on physicochemical properties of shrimp after deep-fat frying were evaluated. Results: The results showed that incorporating GTE (5-20%), increased the moisture content and had a reverse effect on the final oil content in coated fried shrimps. In addition, the peroxide value of the coated shrimp significantly decreased (p<0.5) with the increasing GTE concentration. Adding 10% GTE compared to control sample did not have any significant effect on the L* value but increasing concentrations of GTE from 10 to 20% significantly affected (p< 0.05) L* value of the fried shrimps and L* value of them decreased from 60.35 ±3.4 to 48.5 ± 1.74. Also adding GTE significantly increased (p<0.05) a* value and b * values of the fried shrimps. Conclusions: This study indicated the benefits of adding of GTE into QSM coating and proposed it as a novel active coating.
GRB 090618: Detection of thermal X-ray emission from a bright gamma-ray burst

GRB 090618 was an extremely bright burst, detected across the electromagnetic spectrum. It has a redshift of 0.54 and a supernova (SN) was identified in ground-based photometry. We present a thorough analysis of the prompt and early afterglow emission using data from Swift, Fermi Gamma-ray Burst Monitor and ROTSE, in which we track the evolution of the synchrotron spectral peak during the prompt emission and through the steep decay phase. We find evidence of a thermal X-ray component alongside the expected non-thermal power-law continuum. Such a component is rare among gamma-ray bursts (GRBs), with firm data for only GRBs 060218 and 100316D so far, and could potentially originate from an SN shock breakout, although there remains doubt regarding this explanation for any of the bursts. However, in contrast to these other Swift GRB–SNe with similar thermal signatures, GRB 090618 is a much more ‘typical’ burst: GRB–SNe 060218 and 100316D were both low-luminosity events, with long durations and low peak energies, while GRB 090618 was more representative of the wider population of long GRBs in all of these areas. It has been argued, based both on theory and observations, that most long GRBs should be accompanied by SNe. If this thermal X-ray component is related to the SN, its detection in GRB 090618, a fairly typical burst in many ways, may prove an important development in the study of the GRB–SN connection.
Nano-Hybrids Based on Surface Modified Reduced Graphene Oxide Nanosheets and Carbon Nanotubes and a Regioregular Polythiophene

The multi-walled carbon nanotubes (CNTs) and reduced graphene oxide (rGO) nanosheets were functionalized with 2-hydroxymethyl thiophene (CNT-f-COOTh) and 2-thiophene acetic acid (rGO-f-TAA) and grafted with poly(3-dodecylthiophene) (CNT-g-PDDT and rGO-g-PDDT) to manipulate the orientation and patterning of crystallized regioregular poly(3-hexylthiophene) (P3HT). Distinct nano-hybrid structures including double-fibrillar (5.11−5.18 S/cm), shish-kebab (2.19−2.28 S/cm), and stem-leaf (6.96−7.51 S/cm) were developed using modified CNTs and P3HT. The most effective parameter on morphology of donor-acceptor supramolecules was the surface functionalization and grafting. The electrical conductivities of supramolecules based on P3HT and rGO, rGO-f-TAA, and rGO-g-PDDT ranged in 3.81−3.87, 3.91−3.95, and 10.67−10.70 S/cm, respectively. P3HT chains preferred to interact with their thiophene rings with bared rGO and CNT surfaces, resulting in a conventional face-on orientation. In P3HT/rGO-f-TAA and P3HT/CNT-f-COOTh supramolecular nanostructures patterned with P3HT, the orientation of P3HT chains changed from face-on to edge-on, originating from the strong interactions between the hexyl side chains of P3HTs and functional groups. Nano-hybrids based on grafted rGO demonstrated a patched-like morphology composed of flat-on P3HTs with main backbones perpendicular to the substrate. Based on the ultraviolet-visible and photoluminescence analyses, the flat-on orientation was the best for P3HT chains assembled onto CNT and rGO, which was acquired for CNT-g-PDDT and rGO-g-PDDT nano-hybrids.
A Low-Risk Strategy Based on Higher Moments in Currency Markets

This paper is first to establish profound evidence on the existence of a low-risk anomaly in currency markets. In particular, I discover a novel strategy in currency forward markets that is long in currencies whose higher return moments are low relative to past levels and short in currencies whose higher return moments are high relative to past levels. The low-risk strategy based on higher moments is not spanned by traditional currency strategies. In a sample of roughly 25 years, it provides the highest mean excess payoff and Sharpe ratio as well as the smallest drawdown in comparison to them. The profitability of the strategy is not explained by standard risk factors and limits-to-arbitrage.
Large-Eddy Simulation of turbine wake in complex terrain

We present Large-Eddy Simulation results of a turbine wake in realistic complex terrain with slopes above 0.5. By comparing simulations including and without the wind turbine we can estimate the induction factor, a, and we show how the presence of a strong recirculation zone in the terrain dictates the positioning of the wake. This last finding is in contrast to what would happen in gentle terrain with no substantial increase of turbulent kinetic energy in the terrain induced wakes.
Physiognomic structure of agro-forestry landscapes: method of evaluation and guidelines for design, on the example of the West Polesie Biosphere Reserve

Abstract Harmonious planning of agro-forestry landscapes plays a increasing role in building a social satisfaction flowing from the high quality of the environment on the rural areas. It is also a very good way to create a unique place identity of protected areas, rest areas etc. especially valuable regions. The objectives of the paper are: 1) elaboration the method of evaluation and mapping the physiognomic landscape composition on the rural areas with a high natural values; 2) testing this method on dominated by forests, peatbogs and arable lands the central part of the West Polesie UNESCO Biosphere Reserve (Eastern Poland); 3) formulation of guidelines on the design of landscape interiors and view openings composition, highlighting the unique features of West Polesie landscape and building a sense of the place identity; 4) to show the necessary to enshrine the values of physiognomic landscape composition in land use policy. In evaluation and mapping the landscape composition, a special attention was paid to the role of agro-forest ecotones. The results of the research part of the study as well as a guidelines on landscape design have been presented in the form of a map, study figures and a description.
Internal Tandem Duplication of FLT3 Gene in Egyptian Adult Acute Myeloid and Acute Lymphoblastic Leukemia

Background: FLT3 plays an important role in stem cell proliferation, differentiation, and survival. The most common mutation in the FLT3 gene is internal tandem duplication (FLT3/ITD). Several studies have demonstrated that FLT3 mutations are a strong detrimental prognostic factor in AML and ALL. Aim: Our study was designed to evaluate the relative frequency of FLT3/ITD status in adult AML and ALL patients and its possible impact on response to treatment and overall survival. Patients and Methods: This study was carried out on 110 newly diagnosed adult acute leukemia cases including 61 AML and 49 ALL. Bone marrow or peripheral blood samples were collected from patients at diagnosis. All samples were analyzed for mutation in exon 11 of the FLT3 gene using genomic PCR method. FLT3/ITD appears as an extra PCR band (mutant band) in addition to the 133-bp wild band. ALL cases were treated according to the risk adapted chemotherapy protocol while mature B phenotype cases were excluded from the study. AML cases received induction with 3&7 regimen combing Daunorubicin, 45m/m2 IV day 1-3 and cytosine arabinoside100 mg /m2 by continuous infusion from day 1 to 7 as an induction regimen. Evaluation of response was carried out at the end of induction. Results: FLT3/ITD mutant band was found in 21.3 % (13 / 61) of AML cases. The highest frequency of FLT3/ITD was associated with M3 (40%) followed by M5 (37.5%) and M4 (33.3%), less frequent in M2 (13.6%), M1 (13.3%) and none in M0 and M7. In ALL cases FLT3/ITD was detected in (5/44) 10.2%. The highest frequency was associated with precursor B phenotype (11.4%) and less in T- ALL patients (7.1%). No association was detected between the FLT3/ITD on one side and age, gender, high leucocytic count, BM blasts, DNA index or CD34 expression on the other side in either AML or ALL. We could not find statistically significant difference in response to treatment between FLT3/ITD positive and negative cases in either AML or ALL patients. Conclusion: FLT3/ITD in our AML patients was 21.3 % which is comparable to the literature. However in adult ALL it was much higher than that reported in literature. In contrast to the literature we failed to demonstrate a detrimental effect of FLT3/ITD on treatment outcome in adult AML patients. Further study on a large scale is recommended to identify the prognostic impact of FLT3/ITD in adult ALL. (Journal of American Science 2010;6(9):344-352). (ISSN: 1545-1003).
