Preparation and Microwave Absorption Properties of CoFe2O4-graphene Nanocomposites

: CoFe 2 O 4 -graphene (CFO-GN) nanocomposites were synthesized by in situ co-precipitation method, in-volving homogeneous co-precipitation of Co 2+ and Fe 2+ on the surface of graphite oxides and in situ thermal reduction of graphite oxides simultaneously. The morphology, structure, composition and microwave absorption properties of the nanocomposites were characterized and analyzed by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray energy dispersive spectroscope (EDS), thermogra-vimetric analyzer (TGA), Fourier transform infrared spectroscope (FT-IR) and vector network analyzer (VNA). The results indicate that the CoFe 2 O 4 nanoparticles are uniformly dispersed on the interlayer and surface of the graphene sheets, CoFe 2 O 4 -graphene nanocomposites possess dielectric loss and magnetic loss, and exhibit excellent microwave absorption properties. The reflection losses of the nanocomposites with 88.62wt% and 74.53wt% CoFe 2 O 4 are up to − 11.0 dB and − 12.4 dB, respectively, the bandwidths of reflection loss below − 8 dB are 2.0 GHz and 4.3 GHz, respectively. The nanocomposites with higher content of graphene exhibit higher dielectric loss and reflection loss, wider absorption band, and thus exhibit better microwave absorption properties.
H2 LMI-based Robust Control for Damping Oscillations in Power Systems

This paper presents a study on a robust H2 LMI-based damping control scheme, for improving the inter-area mode oscillations of power systems. A reduced order centralised controller is designed for a 16-machine, 5-area power system (138th order) model reinforced with a thyristor controlled series capacitor (TCSC) to improve the damping of the critical inter-area modes by employing appropriate signal measurements. The effectiveness of the linear matrix inequalities (LMl) formulation, using pole location constraints, of the problem is illustrated. Robustness to faults and unknown disturbances is guaranteed via the design procedure. The performance of the designed system is assessed itt the frequency domain and via appropriate time-domain simulations based upon the non-linear model under various scenario.
Application of model selection technique in chemogenomic data analysis

With the advent of high‐throughput chemogenomic data, it becomes crucially important to extract the important genes which influence the drug activities among the huge number of candidate genes. By employing model selection technique, especially designed for high‐dimensional data, we propose to develop a systematic approach to construct the network elucidating the dependency relationships among the drugs and the genes. Based on the extended Bayesian Information Criterion, we are able to select the best parsimonious network structure. A real National Cancer Institute (NCI)‐60 panel data set is analyzed to demonstrate the utility of the method. The biological implications of the results are discussed.

Optical activation and excitation mechanisms of Er implanted in Si.

The several processes required to achieve Er luminescence in Si are investigated. In particular, the role of Er-O interactions to obtain the incorporation of high Er concentrations, electrically and optically active, in crystalline Si is addressed. Multiple Er and O implants were performed on n-type (100)Si crystals to obtain flat concentrations of ∼1× 19 Er/cm 3 and ∼1×10 20 O/cm 3 over an ∼2-μm-thick layer. These implants produced also a 2.3-μm-thick amorphous Si (a-Si) layer. A subsequent thermal treatment at 620 o C for 3 h induced the epitaxial regrowth of the whole layer and the incorporation of both Er and O in a good-quality single crystal
Sustainibility ahd Efficiency of Dairy Farms Biosecurity Plans

Basic principles of biosecurity plans creation and inplementation were given in this review paper. This include goals wanted to be acheived related to specificities of dairy farm technology, sellection of measures that have to be included, order and manner of measures description, inplementation, as well as failures in plan execution. Efficiacy and further sustainibility of biosecurity plans inplementation could be measured through differences between biosecurity level before and after plans application established by questionnaire about biosecurity indicators, such as: 1. isolation of the farm and its organization, 2. quarantine and newly purchased cows policy, 3. visitors policy, 4. attitude towards equipment use, 5. pest control, 6. sanitation efficasy and 7. farm impact on environment. The stakeholders have to define and develop plan to keep potential pathogens for dairy herd health and production in cooperation with the veterinarian and the other professionals advising on organisation and production technology. At least once a year, it is necessary to reconsider the plan and supplemented by new practical experience and scientific knowledge.
A numerical dynamo benchmark

We present the results of a benchmark study for a convection-driven magnetohydrodynamic dynamo problem in a rotating spherical shell. The solutions are stationary aside from azimuthal drift. One case of non-magnetic convection and two dynamos that differ in the assumptions concerning the inner core are studied. Six groups contributed numerical solutions which show good agreement. This provides an accurate reference standard with high confidence. © 2001 Elsevier Science B.V. All rights reserved.
In vitro and in vivo pharmacological characterization of BIIL 284, a novel and potent leukotriene B(4) receptor antagonist.

BIIL 284 is a new LTB(4) receptor antagonist. It is a prodrug and has negligible binding to the LTB(4) receptor. However, ubiquitous esterases metabolize BIIL 284 to the active metabolites BIIL 260 and BIIL 315, the glucuronidated form of BIIL 260. Both metabolites have high affinity to the LTB(4) receptor on isolated human neutrophil cell membranes with K(i) values of 1.7 and 1.9 nM, respectively. On vital human neutrophilic granulocytes K(i) was around 1 nM. BIIL 260 and BIIL 315 interact with the LTB(4) receptor in a saturable, reversible, and competitive manner. BIIL 260 and its glucuronide BIIL 315 also potently inhibited LTB(4)-induced intracellular Ca(2+) release in human neutrophils (IC(50) values of 0.82 and 0.75 nM, respectively) as measured with Fura-2. High efficacy of BIIL 284 has been demonstrated in various in vivo models. BIIL 284 inhibited LTB(4)-induced mouse ear inflammation with ED(50) = 0.008 mg/kg p.o. , LTB(4)-induced transdermal chemotaxis in guinea pigs with ED(50) = 0.03 mg/kg p.o. , LTB(4)-induced neutropenia in various species (monkey: ED(50) = 0.004 mg/kg p.o. ), and LTB(4)-induced Mac1-expression in monkeys (ED(50) = 0.05 mg/kg p.o. in Tylose). Full blockade of LTB(4) receptors over 24 h was achieved by 0.3 mg/kg BIIL 284 after single oral dose as measured by LTB(4)-induced neutropenia or Mac1-expression in the monkey model. BIIL 284 is an unusually potent and long-acting orally active LTB(4) antagonist, and is therefore under clinical development as a novel anti-inflammatory principle.
Social and environmental enrichment has different effects on ethanol and sucrose consumption in mice

Factors leading to the harmful consumption of substances, like alcohol and sucrose, involve a complex interaction of genes and the environment. While we cannot control the genes we inherit, we can modify our environment. Understanding the role that social and environmental experiences play in alcohol and sucrose consumption is critical for developing preventative interventions and treatments for alcohol use disorders and obesity.
Mortality prediction with a single general self-rated health question

AbstractOBJECTIVE: Health planners and policy makers are increasingly asking for a feasible method to identify vulnerable persons with the greatest health needs. We conducted a systematic review of the association between a single item assessing general self-rated health (GSRH) and mortality. DATA SOURCES: Systematic MEDLINE and EMBASE database searches for studies published from January 1966 to September 2003. REVIEW METHODS: Two investigators independently searched English language prospective, community-based cohort studies that reported (1) all-cause mortality, (2) a question assessing GSRH; and (3) an adjusted relative risk or equivalent. The investigators searched the citations to determine inclusion eligibility and abstracted data by following a standarized protocol. Of the 163 relevant studies identified, 22 cohorts met the inclusion criteria. Using a random effects model, compared with persons reporting “excellent” health status, the relative risk (95% confidence interval) for all-cause mortality was 1.23 [1.09, 1.39], 1.44 [1.21, 1.71], and 1.92 [1.64, 2.25] for those reporting “good,” “fair,” and “poor” health status, respectively. This relationship was robust in sensitivity analyses, limited to studies that adjusted for comorbid illness, functional status, cognitive status, and depression, and across subgroups defined by gender and country of origin. CONCLUSIONS: Persons with “poor” self-rated health had a 2-fold higher mortality risk compared with persons with “excellent” self-rated health. Subjects’ responses to a simple, single-item GSRH question maintained a strong association with mortality even after adjustment for key covariates such as functional status, depression, and co-morbidity.
Shikonin Inhibited Migration and Invasion of Human Lung Cancer Cells via Suppression of c‐Met‐Mediated Epithelial‐to‐Mesenchymal Transition

Epithelial‐to‐mesenchymal transition (EMT) is a major process to regulate cell migration and invasion. Inhibition of epidermal growth factor receptor (EGFR)‐mediated EMT by tyrosine kinase inhibitors (TKIs) is a strategy to prevent lung cancer invasion. However, drug resistance is emerged and accelerated invasion through other signaling bypassing EGFR after TKIs therapy. c‐Met signaling pathway is highly activated in EGFR‐mutated lung cancer cells. Targeting c‐Met signaling pathway may be a strategy to suppress EGFR‐independent migration and invasion for lung cancer therapy. Therefore, we examined the anti‐migration and anti‐invasion abilities of shikonin, an active compound from Lithospermum erythrorhizon, in highly and ligand‐induced c‐Met activation lung cancer cells. Our results revealed that cell viability and cell cycle progression did not change under 1 μM of shikoinin treatment in highly c‐Met expressive HCC827 lung cancer cells. Endogenous c‐Met activation was dose‐dependently inhibited and the migration and invasion activity of HCC827 cells were suppressed by shikonin treatment. Induction of E‐cadherin expression and inhibition of vimentin, slug, and snail expression by shikonin was through c‐Met‐mediated PI3K/Akt and ERK signaling suppression. Furthermore, hepatocyte growth factor (HGF)‐induced migration, invasion and EMT marker change were reversed by shikonin in low c‐Met expressive A549 lung cancer cells. Inhibition of HGF‐induced c‐Met, PI3K/Akt and MEK/ERK activation were observed in shikonin‐treated cells. Co‐treatment of PI3K/Akt inhibitor or ERK inhibitor with shikonin enhanced shikonin‐reversed HGF‐regulated EMT marker expression. Taken together, the results suggested that the anti‐migration and anti‐invasion activities of shikonin was through c‐Met inhibition and following by EMT suppression in lung cancer. J. Cell.

Warren revisited: Atmospheric freshwater fluxes and ''Why is no deep water formed in the North Pacific''

[1] Warren's [1983] “Why is no deep water formed in the North Pacific” is revisited. His box model of the northern North Pacific is used with updated estimates of oceanic volume transports and boundary freshwater fluxes derived from the most recent data sets, using diverse methods. Estimates of the reliability of the result and its sensitivity to error in the data are given, which show that the uncertainty is dominated by the large observational error in the freshwater fluxes, especially the precipitation rate. Consistent with Warren's conclusions, it is found that the subpolar Atlantic-Pacific salinity contrast is primarily explained by the small circulation exchange between the subpolar and subtropical gyres, and by the local excess of precipitation over evaporation in the northern North Pacific. However, unlike Warren, we attribute the latter excess to atmospheric water vapor transports, in particular the northern moisture flux associated with the Asian Monsoon. Thus the absence of such a large transport over the subpolar North Atlantic may partly explain why it is so salty, and why deep water can form there and not in the North Pacific.
Pilot study: rapamycin in advanced hepatocellular carcinoma

Background The PI3K/Akt/mTOR signal pathway is involved in hepatocarcinogenesis. Rapamycin (=sirolimus), a specific mTOR inhibitor, leads to G(1) arrest of many malignant cell lines and currently, analogues of rapamycin are being investigated as a cancer chemotherapeutic adjuvant.
Bringing Another Perspective to Bear on the Factor Structure of the Minnesota Multiphasic Personality Inventory-2

A hierarchical factor solution on the Minnesota Multiphasic Personality Inventory—2 standardization sample found a general psychopathology factor and 4 primary factors similar to those reported by J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer (1989).
Labor Market Cycles and Unemployment Insurance Eligibility

If entitlement to Unemployment Insurance (UI) benefits must be earned with employment, generous UI is an additional benefit to an employment relationship, so it promotes job creation. If individuals are risk neutral, UI is fairly priced, and the UI system prevents moral-hazard, the generosity of UI has no effect on unemployment. As with Ricardian Equivalence, this result should be useful to pinpoint the effects of UI to violation of its premises. In itself, the endogenous entitlement of UI benefits does not resolve if the Mortensen-Pissarides model is able to generate realistic cycles. However, it brings some insights into this debate: The widespread concern in the design of UI systems to minimize moral-hazard unemployment only makes sense if workers have sufficiently high values of leisure (80 percent of labor productivity in our baseline calculation for the United States). Also, the fact that the generosity of UI has potentially a small effect on unemployment reconciles a high response of unemployment to changes in labor productivity with a small response to changes in UI benefits.
Mind the ( Gender ) Gap A Follow-up Experimental Analysis of Gender Differences in Performance in Competitive Environments June 2005

Gender differences in the composition of competitive high-profile jobs have persistently contributed to the gender gap in earnings among men and women. Social scientists have suggested two important explanations for workforce gender inequity: discrimination and differences in preferences. In their landmark paper, Uri Gneezy, Muriel Niederle, & Aldo Rustichini (2003) presented experimental evidence for an additional factor: controlling for ability, women may be less effective than men in competitive environments. They observed no gap in mean performance in the non-competitive piece rate and a significant gap in the competitive tournament; the effect was stronger in mixed groups, as women competed against women in single-sex groups. In this paper, I test for the robustness of their study by adopting and rerunning two important details of their experimental design: (1) a comparison of tournament and piece rate performance as a measure of “competitiveness” and (2) the task of mazes. I also introduce a new task for which women excel, matching pictures, to see if their results are generalizable across tasks. Like the previous study, we also find a gap in the competitive tournament; however, we find that women significantly learned or competed against men, although the improvement was not substantial. We find for matching pictures a gap in favor of women in the piece rate but no gap in tournament performance for mixed groups; however, men significantly learned or competed against men. In general, we find that men improve significantly, compete, or learn more than women for both tasks.
Clonal analysis of murine graft-vs-host disease. II. Leukokines that stimulate fibroblast proliferation and collagen synthesis in graft-vs. host disease.

T lymphocyte clones were established from mice with acute and chronic graft-vs-host disease (GVHD) [C57B6/6 (B6) mice transplanted i.v. with LP/J spleen cells] and immune mice (LP/J mice immunized intraperitoneally with B6 spleen cells). To determine the role of leukokines in the increased collagen production that characterizes chronic GVHD, the supernatants of in vitro stimulated clones were assayed for their effect on 1) B6 embryonic fibroblast proliferation, 2) total fibroblast collagen secretion, and 3) collagen secretion per fibroblast. Four of nine chronic GVHD (CG) clones stimulated both total collagen secretion and collagen secretion per fibroblast, but none stimulated fibroblast proliferation. Six of 10 immune (I) clones stimulated fibroblast proliferation, and none stimulated collagen secretion per fibroblast. Acute GVHD (G) clones were heterogeneous; 2/10 G clones stimulated fibroblast proliferation, 5/10 stimulated total collagen secretion, and 4/10 stimulated collagen secretion per fibroblast. I and CG clones may act synergistically in vivo. The presence of CG-like clones in mice with acute GVHD suggest that the immunologic events that culminate in chronic GVHD are initiated early after transplantation.
Current status of prevalence of goiter and iodine content of salt consumed in District Solan, Himachal Pradesh.

The Solan district of Himachal Pradesh is known to be an iodine deficiency endemic area. In response to this the state government issued a ban on the sale of non-iodized salt for human consumption in 1976. During 1993-96 a joint project between the Indian government and the UN International Childrens Emergency Fund (UNICEF) undertook intensive efforts to ensure that only iodized salt was available to the population. To assess the prevalence of goiter and to estimate the iodine content of salt consumed by the population in the district a study using multistage cluster sampling was conducted in 1997 among children aged 8-10 years. On-the-spot urine samples were collected from 10.7% of the subjects. Urine iodine excretion (UIE) was determined by wet digestion method. Overall a total of 6724 schoolchildren (3377 males and 3347 females) were studied. The total goiter prevalence rate was found to be 11.3% (indicating mild iodine deficiency) while the median UIE was 15.0 mcg/dl (indicating no biochemical iodine deficiency in the population). The findings suggested that Solan district is in a transition phase from iodine deficient to iodine sufficient. These findings indicate that elimination of iodine deficiency disorder can be achieved by continued and sustained supply of the iodized salt with adequate quantity of iodine to the entire population.
Variation of the cognitive activity in different types of verbal fluency tasks.

On this study we have applied ten Verbal Fluency tasks belonging to phonological, categorial, grammatical and combined forms to 259 Argentinean adults (age 15 to 70, n=259). We calculate their relationship with executive, attentional and semantic neuropsychological tasks using regression analysis. Executive, attentional and semantic scores were entered like independent variables and each verbal fluency task were entered like dependent ones. Also we revised the theoretical structure of each Verbal Fluency Task to address their putative data variations Results showed significative different cognitive predictive models between the verbal fluency tasks, as between as into each form. The final objective of this research was to develop a Verbal Fluency Neuropsychological Explorer, able to screen cognitive functions in short time and in difficult situations. In order to reach that we consider this research an approach needed to complement with neuroimaging, psychometric and clinical studies.
Cheating Is Not Playing: Methodological Issues of Computational Game Theory

Computational Game Theory is a way to study and evaluate behaviors using game theory models, via agent-based computer simulations. One of the most known example of this approach is the famous Classical Iterated Prisoner's Dilemma (CIPD). It has been popularized by Axelrod in the beginning of the eighties and had led him to set up a successful Theory of Cooperation. This use of simulations has always been a challenging application of computer science, and of agent-based approaches, in particular to Social Sciences. It may be viewed as Empirical Game Theory. These kind of approach is often necessary since, in the general case, classical analytical ones do not give suitable results. These tools are also often used when full game-theoretic analysis is intractable. The usual method to evaluate behaviors consists in the collection of strategies, through open contests, and the confrontation of all of them as in a sport championship. Then it becomes, or at least seems to become, easy to evaluate and compare the efficiency of these behaviors. Evaluating strategies can however not be done efficiently without the insurance that algorithms used are well formed and that they can not introduce bias in their computation. It can not be done without tools able to prevent or, at least, measure deviation from the object of the study. Unfortunately people using such simulations often do not take care seriously about all those aspects, because they are not aware of it, and sometimes because they are. We will try to show effects of bad simulations practice on the simplest example. We show methodological issues which have to be taken care of, or avoided in order to prevent trouble in simulation results interpretation. Based on some simple illustration, we exhibit two kinds of bias that could be introduced. We classify them as voluntary or involuntary mistakes. The former ones can be explained by poor design of experimentations whereas the latter can defeat the purpose of the evaluation using simple ideas of agreement and cooperation. We also show the implications on interpretations and conclusions that such errors may produce. We state that scoring/ranking methods are part of the game, and as such have to be described with the game. Many points described may seem to be widely known. We think that with the growth of interest of such methods they have to be detailed and exposed clearly.
A natural experiment in school accountability: the impact of school performance information on pupil progress and sorting

We test the hypothesis that the publication of school performance tables raises school effectiveness. Our data allow us to implement a classic difference-in-difference analysis comparing outcomes in England and Wales, before and after the abolition of the tables in Wales. We find significant and robust evidence that this reform markedly reduced school effectiveness in Wales. There is significant heterogeneity across schools: schools in the top quartile of the league tables show no effect. We also test whether the reform reduced school segregation in Wales, and find no systematic significant impact on either sorting by ability or by socioeconomic status.
