The ultraviolet / optical variability of steep-spectrum radio quasars : the change in accretion rate ?

Context. The steep-spectrum radio quasars (SSRQs) are powerful radio sources, with thermal emission from accretion disk and jet nonthermal emission both likely contributing to the ultraviolet (UV)/optical luminosity; however, the former may play a dominant role. Since the UV/optical variability of SSRQs has been poorly studied, little is known about the mechanism of their variability. Aims. We investigate the mechanism of the UV/optical variability of SSRQs. Methods. A sample of eighteen SSRQs was established in SDSS Stripe 82 region in our previous works, in which the flux and spectral variability were studied. In this work, we construct the flux-flux diagram using SDSS u and i multi-epoch data for these eighteen SSRQs. The standard accretion disk model is used to fit the flux-flux variations, in order to explore the variability mechanism. Results. The model fit to flux-flux diagram are tuned with fixed black hole mass and varying accretion rate. We find that the flux-flux diagram of all our SSRQs can be qualitatively described by the standard accretion disk model with a change in the accretion rate. Although nonthermal jet power-law emission can also qualitatively reproduce the variability, the reasonable accretion rates and black hole masses required to fit the flux-flux variations suggest that a disk emission with variable accretion rate is a plausible description of the data.
Semantic override of low-level features in image viewing - both initially and overall

Guidance of eye-movements in image viewing is believed to be controlled by stimulus driven factors as well as viewer dependent higher level factors such as task and memory. It is currently debated to what proportions these factors contribute to gaze guidance, and also how they vary over time after image onset. Overall, the unanimity regarding these issues is surprisingly low and there are results supporting both types of factors as being dominant in eye-movement control under certain conditions. We investigate in this paper how low, and high level factors influence eye guidance by manipulating contrast statistics on images from three different semantic categories and measure how this affects fixation selection. Our results show that the degree to which contrast manipulations affect fixation selection heavily depends on an image’s semantic content, and how this content is distributed over the image. Over the three image categories, we found no systematic differences between contrast and edge density at fixated location compared to control locations, neither during the initial fixation nor over the whole time course of viewing. These results suggest that cognitive factors easily can override low-level factors in fixation selection, even when the viewing task is neutral. (Less)
Exercising with Baxter: Design and Evaluation of Assistive Social-Physical Human-Robot Interaction

The worldwide population of older adults is steadily increasing and will soon exceed the capacity of assisted living facilities. Accordingly, we aim to understand whether appropriately designed robots could help older adults stay active and engaged while living at home. We developed eight human-robot exercise games for the Baxter Research Robot with the guidance of experts in game design, therapy, and rehabilitation. After extensive iteration, these games were employed in a user study that tested their viability with 20 younger and 20 older adult users. All participantswerewilling to enter Baxter’s workspace and physically interact with the robot. User trust and confidence in Baxter increased significantly between preand post-experiment assessments, and one individual from the target user population supplied us with abundant positive feedback about her experience. The preliminary results presented in this paper indicate potential for the use of two-armed humanscale robots for social-physical exercise interaction.
Formulation and In Vitro Evaluation of Lansoprazole Delayed Release Capsules

The Present research work is “formulation and evaluation of lansoprazole delayed release capsules 30mg” is a category of proton pump inhibitor (PPI) used in treatment of gastro esophageal reflux disease (G.E.R.D), erosive esophagitis (E.E) and acid – related disorders. Lansoprazole is an acid labile drug. It degrades in the acidic environment of the stomach thus leading to therapeutic inefficacy. Therefore it is necessary to bypass the acidic p H of the stomach. The present research work emphasis mainly on selection of drug that is lansoprazole and excipients of various like HPC-L and eudragit L30 D55 were used as enteric polymers. The enteric coated pellets were prepared by suspension layering technique in fluidized bed processor (FBP). Ten Formulations (F1 - F10) lansoprazole enteric coated pellets were prepared varying the compositions of drug loading, barrier coating and enteric coating. The prepared pellets were studied for their physico- chemical properties, assay and in vitro release studies. The release kinetics was analyzed using zero-order model, first-order model and higuchi , s square rot equation. FT-IR was performed to know the compatibility of the drug with various excipients and SEM analysis was performed to know the morphology of the pellet. All the 10 formulations are kept for Stability studies and carried out for 3 months at 40°C/75 %RH and 25°C/60 % RH according to ICH guidelines. The optimized formulation F 10 was shown desirable in vitro acid and buffer drug release during the stability period and comparable to the innovator.
Study of Growth and Antioxidant Enzymes in Andrographis paniculata (Burm f.) Wall ex Nees. as Influenced by Salinity and Alkalinity

An attempt was made to study the influence of salinity (100mM, 150mM, 200mM and 250mM NaCl) and alkalinity (50mM, 100mM, 150mM and 200mM NaHCO3) on Plant height, Number of Leaves, Leaf Area, Relative Water Content, Catalase and Peroxidase activity of Andrographis paniculata. Untreated plants were kept as control. The plant samples were analyzed for 100 DAS at every 20 days interval. The results indicated that the reduction in growth parameters were abrupt in Andrographis and decreased in above mentioned growth parameters at high salt concentrations (250mM NaCl and 200mM NaHCO3) were observed. Similarly, alteration in the antioxidant enzymes viz. catalase(CAT) and peroxidase (POD) activity was observed in all the treatment. The maximum increment in CAT and POD activity was recorded at 200mM NaCl and 150mM NaHCO3. The results revealed that the extent of alkaline stress induced changes was higher than saline stress and alkaline conditions impose more deleterious effect on Andrographis plant.
Leverage Effect and Market Efficiency of Kuala Lumpur Composite Index

Stock market is a main source for raising new private capital in many developing countries including Malaysia. Therefore, its efficiency and leverage effect is utmost important and interest. This paper aims to estimate the leverage effect of Malaysian stock market using EGARCH as well as investigating its efficiency using Augmented Dickey-Fuller (ADF). Data used consists of weekly closing prices for Malaysia stock market indices, namely the Kuala Lumpur Composite Index (KLCI), from 9 January 2004 to 8 Jun 2007. Results show that the EGARCH model did not confirm the existence of the leverage effect. The KLCI possess a unit root with no trend but with drift or known as random walk drift. It suggests that KLCI is weak form hypothesis.
Effects of Piperonyl Butoxide and Tetramethrin Combinations on Biological Activities of Selected Synthetic Pyrethroid Insecticides against Different Housefly (Musca domestica L., Diptera: Muscidae) Populations

Cakir G. , O. Yavuz, O. Kocak: Effects of Piperonyl Butoxide and Tetramethrin Combinations on Biological Activities of Selected Synthetic Pyrethroid Insecticides against Different Housefly (Musca domestica L., Diptera: Muscidae) Populations. Acta Vet. Brno 2008, 77: 467-474. Piperonyl butoxide (PBO), a methylenedioxyphenyl compound, is primarily used as a synergist in combination with space spray, residual and admixture products for the control of insect pests in or around domestic and commercial premises, especially food preparation areas. Also, tetramethrin is known as a knockdown agent on target organism and it is generally used with piperonyl butoxide. In this study, effects of piperonyl butoxide and tetramethrin combinations on biological activities of synthetic pyrethroids, cypermethrin, deltamethrin, and permethrin against different housefly (Musca domestica Linnaeus, 1758) populations were evaluated. In addition, the biological efficiency of the insecticides used in the study, insecticide + PBO and insecticide + PBO + tetramethrin combinations, against the WHO standard sensitive housefly population and housefly populations collected from different parts of Turkey were compared. Results showed that PBO extensively promoted the ratio of knockdown and killing effect values of the insecticides. The results also indicated that PBO and PBO + tetramethrin combinations moderately reduced the knockdown effect times of all formulation in all housefly populations. The knockdown effect times were more decreased by insecticide + PBO + tetramethrin combinations than insecticides that are used alone and insecticide + PBO combinations.

Relationships Between Traditional Metrics and Altmerics: A Case Analysis of PLoS

The possibility of creating and easily distributing something via a digital platform creates an enormous material volume. With the increase of scientific publications it becomes harder for scholars to choose the most related and significant resources from the others (Henning & Gunn, 2012). Bibliometrics measures the impact of scholars between each other, but the impact of articles across the entire web is not limited by this. On the other hand, altmetrics measures the impact of articles from the web, alongside bibliometric data. The aim of this study is to investigate the probable relationships between traditional metrics and altmetrics by analysing the PLoS Article-Level Metric (ALM) dataset.
Environmental Fiscal Reform in Namibia

In this article, the likely effects of an environmental fiscal reform in Namibia are examined using a Computable General Equilibrium model. We find that a triple dividend—improving the environment, increasing employment, and reducing poverty at the same time—remains elusive. Subsidizing unskilled labor would give the most favorable result in terms of real GDP and employment, but the worst in terms of environmental effects. Transfers targeted toward poorer households have the best distributional and environmental impacts, but do not lead to increases in GDP or employment. Thus there is scope to create additional benefits for society through the various environmental fiscal reform options studied, but there is no option that clearly outperforms the others in all respects.
The Impact of Affective Commitment in Employees Life Satisfaction

A commitment refers to attachment and loyalty. An affective commitment is an employee’s emotional attachment to, identification with and involvement in an organization. It influence personal characteristics, structural characteristics, and work experiences. The purpose of it is study is to analyse the role of affective commitment in employee’s life satisfaction. Life satisfaction is the embodiment of a global judgment about one’s life taken as a whole. It is positive evaluation of the condition of one’s life, judgment. In this study sample includes 200 employees of NTPC of India from Sonbhadra District. The sample consisted of managerial employees who volunteered to participate in the study.The data has been analysing by descriptive analysis, correlation, linear regression, and ANOVA. The results were found that organizational affective commitment is highly significantly related with life satisfaction among managerial employees.
Hepatic Dysfunction in Diabetes Mellitus : Biochemical and Ultrasonological Study

A cross-sectional study was conducted among 100 patients of type 2 diabetes in the OPD to evaluate hepatic dysfunction. The objectives of the study are to clinically evaluate patients with type 2 DM for the presence of hepatic dysfunction and to find out liver changes both ultrasonologically and biochemically in type 2 diabetic patients. This prospective study was conducted on type 2 diabetic cases admitted as well as attending OPD in Sri Siddhartha Medical College and Hospital, Tumkur, between October, 2011 and April, 2013. The cases who were diagnosed as type 2 diabetic, irrespective of duration of the diabetes were selected randomly. The mean age of the patients was 59.32 years. Majority of type 2 DM patients belonged to 51-60 years age group. Females outnumbered males in this study. The maximum duration of DM was 20 years and minimum duration was one year. Majority of males and females had diabetes for 1-5 years. Out of 100 patients, 51% had good glycemic control (HbA1c ≤7) and 49% had unsatisfactory glycemic control (HbA1c >7). About 54% of the patients had minimum 1 abnormality of the liver function tests. Majority of the diabetics were aged between 51-60 years. Liver function test abnormalities were found in 54 patients (54%) showed a direct relationship with increasing duration of diabetes since diagnosis (p=0.007). HbA1c value 7 is associated with 37% of cases with abnormal LFTs (p=0.000). The results bear out the close relation between diabetics and liver functions. In our study, age of the patient did not seem to have definite influence on effect of diabetes on liver function tests. But, the duration of diabetes did seem to have some influence on effect of diabetes on the functions of liver. These results show that poor the glycemic control, the frequency of abnormal liver function increases.
Thermodynamics of metalloprotein electron transfer reactions

Thin—layer spectroelectrochemical methods have been used to determine the formal reduction potentials of several electron transfer metalloproteins in the temperature range 5—40°C (5—26°C for plastocyanin). Measurements were made using OTTLE cells in a nonisothermal configuration. Electron transfer reaction entropies ('c ed 5x) at 25°C (pH 7, T 0.1 N) derived from these measurements are as follows: cytochrome c (horse heart), —14.9 ± 1.2; cytochrome c2 (Rhodospirillum rubrum), —9.6 ± 1.2; cytochrome c (Pseudomonas aeruinosa), —16.2 ± 1.2; HiPIP (Chro— matium vinosum), —. O ± 1.2; azurin (Pseudomonas aeruginosa), —16.1 ± 1.2; stellacyanin (Rhus vernicifera), —4.2 ± 1.2; plastocyanin (Phaseolus vulgaris), —2.4 ± 1.2 eu. In all cases the AH° values are negative. The fact that the A5c values are more negative than inorganic complexes with low inner sphere electron transfer barriers is discussed in terms of changes in protein—solvent interactions that could accompany reduction. Either increased solvent ordering in the protein interior or a more compact protein structure in which solvent is excluded could account for the observed loss in entropy in the reduced solution state.
Asset Market Liquidity Risk Management: A Generalized Theoretical Modeling Approach for Trading and Fund Management Portfolios

Asset market liquidity risk is a significant and perplexing subject and though the term market liquidity risk is used quite chronically in academic literature it lacks an unambiguous definition, let alone understanding of the proposed risk measures. To this end, this paper presents a review of contemporary thoughts and attempts vis-a-vis asset market/liquidity risk management. Furthermore, this research focuses on the theoretical aspects of asset liquidity risk and presents critically two reciprocal approaches to measuring market liquidity risk for individual trading securities, and discusses the problems that arise in attempting to quantify asset market liquidity risk at a portfolio level. This paper extends research literature related to the assessment of asset market/liquidity risk by providing a generalized theoretical modeling underpinning that handle, from the same perspective, market and liquidity risks jointly and integrate both risks into a portfolio setting without a commensurate increase of statistical postulations. As such, we argue that market and liquidity risk components are correlated in most cases and can be integrated into one single market/liquidity framework that consists of two interrelated sub-components. The first component is attributed to the impact of adverse price movements, while the second component focuses on the risk of variation in transactions costs due to bid-ask spreads and it attempts to measure the likelihood that it will cost more than expected to liquidate the asset position. We thereafter propose a concrete theoretical foundation and a new modeling framework that attempts to tackle the issue of market/liquidity risk at a portfolio level by combining two asset market/liquidity risk models. The first model is a re-engineered and robust liquidity horizon multiplier that can aid in producing realistic asset market liquidity losses during the unwinding period. The essence of the model is based on the concept of Liquidity-Adjusted Value-at-Risk (L-VaR) framework, and particularly from the perspective of trading portfolios that have both long and short trading positions. Conversely, the second model is related to the transactions cost of liquidation due to bid-ask spreads and includes an improved technique that tackles the issue of bid-ask spread volatility. As such, the model comprises a new approach to contemplating the impact of time-varying volatility of the bid-ask spread and its upshot on the overall asset market/liquidity risk.

Braided Enveloping Algebras Associated to Quantum Parabolic Subalgebras

Associated to each subset J of the nodes I of a Dynkin diagram is a triangular decomposition of the corresponding Lie algebra 𝔤 into three subalgebras (generated by e j , f j for j ∈ J and h i for i ∈ I), (generated by f d , d ∈ D = I∖J) and its dual . We demonstrate a quantum counterpart, generalising work of Majid and Rosso, by exhibiting analogous triangular decompositions of U q (𝔤) and identifying a graded braided Hopf algebra that quantizes . This algebra has many similar properties to , in many cases being a Nichols algebra and therefore completely determined by its associated braiding.
THE MSU/NSCL RE-ACCELERATOR ReA3*

The National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University (MSU) is currently constructing its new reaccelerated beam facility: ReA3. ReA3 will provide unique low-energy rare isotope beams by stopping fast rare isotopes in gas stopping systems and reaccelerating them in a compact linac. The main components, which will be explained in this paper, are a linear cryogenic gas cell to stop the fast beams produced by projectile fragmentation, an Electron Beam Ion Trap (EBIT) charge state booster, a room temperature Radio Frequency Quadrupole (RFQ) and a linac utilizing superconducting quarter wave resonators. An achromatic beam transport and distribution line towards the new experimental area will complete ReA3. Beams from ReA3 will range in energy from 0.3 to 6 MeV/u: the maximum energy is 3 MeV/u for heavy nuclei such as uranium, and 6 MeV/u for ions with A<50, as the charge state of the ions can be adjusted by the EBIT. ReA3 will provide pioneering beams for nuclear physics research, initially using beams from the Coupled Cyclotron Facility at NSCL and later providing reacceleration capability for the next-generation rare isotope facility FRIB that will be hosted at MSU. The ReA3 concept and status of ReA3 are presented, with particular emphasis on the superconducting linac.
