Ubiquitous Interplay Between Charge Ordering and High-Temperature Superconductivity in Cuprates

Besides superconductivity, copper-oxide high-temperature superconductors are susceptible to other types of ordering. We used scanning tunneling microscopy and resonant elastic x-ray scattering measurements to establish the formation of charge ordering in the high-temperature superconductor Bi2Sr2CaCu2O8+x. Depending on the hole concentration, the charge ordering in this system occurs with the same period as those found in Y-based or La-based cuprates and displays the analogous competition with superconductivity. These results indicate the similarity of charge organization competing with superconductivity across different families of cuprates. We observed this charge ordering to leave a distinct electron-hole asymmetric signature (and a broad resonance centered at +20 milli–electron volts) in spectroscopic measurements, indicating that it is likely related to the organization of holes in a doped Mott insulator. Surface and bulk measurements in bismuth-based cuprates agree and indicate a short-range charge order. [Also see Perspective by Morr] Copper-Oxide Superconductors Copper-oxide superconductors have a complex electronic structure. A charge density order has been observed in two cuprate families; however, it has been unclear whether such an order exists in Bi-based compounds (see the Perspective by Morr). Comin et al. (p. 390, published online 19 December) and da Silva Neto et al. (p. 393, published online 19 December) address this question in single-layer and double-layer Bibased cuprates, respectively. For both families of materials, surface measurements by scanning tunneling spectroscopy agree with bulk measurements obtained through resonant elastic x-ray scattering, which suggests the formation of short-range correlations that modulate the charge density of the carriers over a range of dopings. Thus, charge ordering may represent a common characteristic of the major cuprate families.
Eosinophilia and Thrombosis in Parasitic Diseases: An Overview

It is known that peripheral blood eosinophilia (PBE) is a normal hematopoietic response to several parasitic diseases, but it is less known that PBE promotes a hypercoagulable state that may favor thrombosis. Scope of this article is to explore which parasitic infestations are most likely to be complicated by thrombosis and to highlight the pathogenetic contribution of PBE to vascular occlusions in this setting. A review of the world literature revealed 18 cases in which PBE was associated with vascular occlusion though no specific surveys were dedicated to this topic. The eosinophil exerts its thrombogenic potential by inhibition of the natural anticoagulant pathways and release of tissue factor with enhanced coagulation activation leading to vascular occlusion. It is hoped that this review contributes to the awareness of the link between PBE and thrombosis in parasitic disorders to foster research in this area.
Reexamination of the Role of the Amino Terminus of SecA in Promoting Its Dimerization and Functional State

ABSTRACT The SecA nanomotor promotes protein translocation in eubacteria by binding both protein cargo and the protein-conducting channel and by undergoing ATP-driven conformation cycles that drive this process. There are conflicting reports about whether SecA functions as a monomer or dimer during this dynamic process. Here we reexamined the roles of the amino and carboxyl termini of SecA in promoting its dimerization and functional state by examining three secA mutants and the corresponding proteins: SecAΔ8 lacking residues 2 to 8, SecAΔ11 lacking residues 2 to 11, and SecAΔ11/N95 lacking both residues 2 to 11 and the carboxyl-terminal 70 residues. We demonstrated that whether SecAΔ11 or SecAΔ11/N95 was functional for promoting cell growth depended solely on the vivo level of the protein, which appeared to govern residual dimerization. All three SecA mutant proteins were defective for promoting cell growth unless they were highly overproduced. Cell fractionation revealed that SecAΔ11 and SecAΔ11/N95 were proficient in membrane association, although the formation of integral membrane SecA was reduced. The presence of a modestly higher level of SecAΔ11/N95 in the membrane and the ability of this protein to form dimers, as detected by chemical cross-linking, were consistent with the higher level of secA expression and better growth of the SecAΔ11/N95 mutant than of the SecAΔ11 mutant. Biochemical studies showed that SecAΔ11 and SecAΔ11/N95 had identical dimerization defects, while SecAΔ8 was intermediate between these proteins and wild-type SecA in terms of dimer formation. Furthermore, both SecAΔ11 and SecAΔ11/N95 were equally defective in translocation ATPase specific activity. Our studies showed that the nonessential carboxyl-terminal 70 residues of SecA play no role in its dimerization, while increasing the truncation of the amino-terminal region of SecA from 8 to 11 residues results in increased defects in SecA dimerization and poor in vivo function unless the protein is highly overexpressed. They also clarified a number of conflicting previous reports and support the essential nature of the SecA dimer.

Effect of alcohol intake and cigarette smoking on sperm parameters and pregnancy

Much has been published about smoking and alcohol intake influencing male fertility, sperm parameters and reproductive outcome. However, there is no conclusive agreement about the effects of cigarette smoking and alcohol use on these outcomes and thus no generally accepted guidelines. The combined effect of cigarette smoking and alcohol intake, though, has not been rigorously investigated. Because alcohol consumption and smoking are often seen together, this study focuses on the effect of smoking and drinking habits separately and combined on semen parameters, such as volume, sperm count, motility and morphology, and on pregnancy outcome. These suggested toxic effects are studied in a group of subfertile, asthenozoospermic men (<10% motile spermatozoa), compared with a group of ‘proven fertile’, healthy men. The extreme asthenozoospermic group has especially been chosen because of the suspected effect, that is, oxidative stress, on sperm motility. In our study, we found that cigarette smoking and alcohol intake did not differ between the subfertile and fertile group. In conclusion, cigarette smoking and alcohol consumption do not appear to significantly affect sperm parameters, such as volume, sperm count, motility and morphology or pregnancy outcome in our study population.
Metrical rhythm in speech planning : priming or predictability

We investigated how repeating metrical templates, i.e., stress priming, and the contextual predictability of stress affect behavior in a word naming task. We measured naming latencies and the phonetic duration of words produced under four different conditions (congruent stress, low predictability; congruent stress, high predictability; incongruent stress, low predictability; incongruent stress, high predictability). Results showed strong effects of metrical predictability on both naming latency and word duration but no effect of stress congruency on either variable. The relevance of these results to theories of speech production and phonological representation are discussed.
Disparities in liver transplantation before and after introduction of the MELD score.

CONTEXT In February 2002, the allocation system for liver transplantation became based on the Model for End-Stage Liver Disease (MELD) score. Before MELD, black patients were more likely to die or become too sick to undergo liver transplantation compared with white patients. Little information exists regarding sex and access to liver transplantation. OBJECTIVE To determine the association between race, sex, and liver transplantation following introduction of the MELD system. DESIGN, SETTING, AND PATIENTS A retrospective cohort of black and white patients (> or = 18 years) registered on the United Network for Organ Sharing liver transplantation waiting list between January 1, 1996, and December 31, 2000 (pre-MELD cohort, n = 21 895) and between February 28, 2002, and March 31, 2006 (post-MELD cohort, n = 23 793). MAIN OUTCOME MEASURES Association between race, sex, and receipt of a liver transplant. Separate multivariable analyses evaluated cohorts within each period to identify predictors of time to death and the odds of dying or receiving liver transplantation within 3 years of listing. Patients with hepatocellular carcinoma were analyzed separately. RESULTS Black patients were younger (mean [SD], 49.2 [10.7] vs 52.4 [9.2] years; P < .001) and sicker (MELD score at listing: median [interquartile range], 16 [12-22] vs 14 [11-19]; P < .001) than white patients on the waiting list for both periods. In the pre-MELD cohort, black patients were more likely to die or become too sick for liver transplantation than white patients (27.0% vs 21.7%) within 3 years of registering on the waiting list (odds ratio [OR], 1.51; 95% confidence interval (CI), 1.15-1.98; P = . 003). In the post-MELD cohort, black race was no longer associated with increased likelihood of death or becoming too sick for liver transplantation (26.5% vs 22.0%, respectively; OR, 0.96; 95% CI, 0.74-1.26; P = .76). Black patients were also less likely to receive a liver transplant than white patients within 3 years of registering on the waiting list pre-MELD (61.6% vs 66.9%; OR, 0.75; 95% CI, 0.59-0.97; P = .03), whereas post-MELD, race was no longer significantly associated with receipt of a liver transplant (47.5% vs 45.5%, respectively; OR, 1.04; 95% CI, 0.84-1.28; P = .75). Women were more likely than men to die or become too sick for liver transplantation post-MELD (23.7% vs 21.4%; OR, 1.30; 95% CI, 1.08-1.47; P = .003) vs pre-MELD (22.4% vs 21.9%; OR, 1.08; 95% CI, 0.91-1.26; P = .37). Similarly, women were less likely than men to receive a liver transplant within 3 years both pre-MELD (64.8% vs 67.6%; OR, 0.80; 95% CI, 0.70-0.92; P = .002) and post-MELD (39.9% vs 48.7%; OR, 0.70; 95% CI, 0.62-0.79; P < .001). CONCLUSION Following introduction of the MELD score to the liver transplantation allocation system, race was no longer associated with receipt of a liver transplant or death on the waiting list, but disparities based on sex remain.
Costs and Benefits of a Common Currency for ASEAN

East Asia's Monetary Future is an illuminating and valuable work which uniquely focuses on a long-term monetary view of the region. There are multiple and varied future scenarios which can be applied to this region – an enlarged Singapore–Brunei currency area, a greater China monetary bloc and even a Northeast Asian bloc comprising Japan and Korea.
Assessment of Health Services in Kogi State Public and Private Secondary Schools

This study was conducted to assess the status and scope of health services delivery in Kogi State Public and private secondary schools. Twenty four (12public and 12private) secondary schools were selected across the three senatorial districts of Kogi State i.e Kogi Central, Kogi East and Kogi West. Data were collected from a conveniences sample of 1440 staffs and students of private and public schools (960 students and 480 staff) using school health services questionnaire (SHSQ) consisting of socio-demographic section followed by well validated instruments. Data were analysed using descriptive statistics, t-test analysis of variance (ANOVA). The findings of this study showed an unsatisfactory implementation of school health services in both public and private secondary schools across Kogi state. Among other recommendations, this paper infers that school administrators, policy makers, health professionals should implement a workable school health policy and strategies in promotion of health services in Kogi state.
Social relations, human resource management, andknowledge transfer in work organisations:toward an integrated approach

Hailed as the basis for competitive advantage of contemporary firms, knowledge transfer has recently emerged as a key research topic in the organisation and management field. Despite wide recognition of the importance of social relations for effective knowledge transfer, there is little understanding of the micro-sociological foundations of this process, and even less understanding of the ways in which human resource management practices can support social relations conducive to knowledge transfer and sharing. The present study developed an integrated conceptual model with the aim to improve understanding of the mechanisms for and the conditions under which social relations can be transformed into useful, actionable knowledge. To test this model, quantitative data were gathered through a questionnaire survey of 135 knowledge workers from three Irish-based organisations. Qualitative data were also collected through semi-structured interviews with the human resource managers and knowledge managers of these organisations. The findings demonstrated that, at the interpersonal level of analysis, the effective transfer of knowledge hinges upon the extent to which individuals share a common lexicon for communication and trust each other, both professionally and personally. In particular, personal trust was found to be key to the transfer of tacit knowledge, thereby underlining the importance of positive affect as a criterion for the formation of productive knowledge exchange relations. In regard to the role of human resource management, it was found that employees’ perceptions of reciprocal task interdependence, job feedback, selective staffing, intensive socialisation, and relational-oriented training and development are related strongly to their perceptions of a social climate of teamwork and cooperation and, consequently, of knowledge sharing attitudes. Importantly, the effect of these practices was found to be mediated by employees’ perceptions of line managers’ support for knowledge sharing. The study concluded by suggesting the need for further integration of social relations into research on the role of human resource management practices in knowledge transfer and organisational learning.
0749: Prognostic Factors and Adjuvant Therapy in Uterine Carcinosarcoma

PURPOSE OF INVESTIGATION The objective of this retrospective study was to investigate prognostic variables and impact of adjuvant therapy in uterine carcinosarcoma. METHODS The clinical information and pathological confirmation were reviewed for cases with uterine carcinosarcoma from 1984 to 2005. A total of 45 patients were eligible for analysis. RESULTS The median follow-up for survivors was 84 months. Five-year overall survival and progression-free survival (PFS) rates were 36.5% and 33.8%, respectively for Stage I-IV. Distant site metastasis with/without pelvic failure occurred in 83.3% of those with recurrence/progression. By multivariate analysis, older age (p = 0.001) and more than half of myometrial invasion (p = 0.002) were significant predictors of death, while only myometrial invasion (p = 0.022) was significantly associated with PFS. Stratified analyses demonstrated a monotonic trend of chemotherapy or chemoradiation to decrease death. CONCLUSIONS Our results suggested that age and depth of myometrial invasion were significant prognostic factors, and chemotherapy or chemoradiation seemed to be beneficial for uterine carcinosarcoma.
Black hole thermodynamics from simulations of lattice Yang-Mills theory

We report on lattice simulations of 16 supercharge SU(N) Yang-Mills quantum mechanics in the 't Hooft limit. Maldacena duality conjectures that in this limit the theory is dual to IIA string theory, and, in particular, that the behavior of the thermal theory at low temperature is equivalent to that of certain black holes in IIA supergravity. Our simulations probe the low temperature regime for N{<=}5 and the intermediate and high temperature regimes for N{<=}12. We observe 't Hooft scaling, and at low temperatures our results are consistent with the dual black hole prediction. The intermediate temperature range is dual to the Horowitz-Polchinski correspondence region, and our results are consistent with continuous behavior there. We include the Pfaffian phase arising from the fermions in our calculations where appropriate.
An Improved Path-Following Method for Mixed ${H} _{2} /{H}_{\infty}$ Controller Design

Among the few methods available to solve bilinear matrix inequalities (BMIs) occurring in control design, the path-following method, published some years ago, appears to be one of the best ones, as far as linearization methods are concerned. However, few details are given in the literature about its implementation and limits. In this technical note, this method is applied to the design of mixed H 2/H infin controllers with full details of the algorithm and some improvements over the one which has been published a few years ago. The results obtained with the numerical example given in that same publication, as well as with some other examples, are compared with those given by other methods, including a direct BMI-solving program.
Human Resource Management in Professional Service Firms: Learning from a Framework for Research and Practice

Success in human resource management (HRM) depends on the question of whether applied practices of HRM meet specific contingency factors and are appropriately configured. Using this argument, the present article examines HRM in professional service firms (PSFs) in pursuit of three objectives. First, we introduce a conceptual framework that illustrates how the constitutive characteristics of PSFs, as contingency factors, influence HRM practices and research. Second, based on this framework, we summarize key findings of research on HRM in PSFs and open up potential avenues for further research. Third, we reflect on the argument that HRM in PSFs can contribute to an understanding of HRM practices in other organizational settings, leading to the question of the mutual transferability of HRM practices. Aside from these three primary objectives, we also introduce the contents of the special issue.
Herding and Feedback Trading: Evidence on Their Relationship at the Macro Level

The behavioural expressions of herding and feedback trading maintain properties that render their coexistence a possibility. Although their joint presence has been largely confirmed by empirical work in the Finance literature at the micro level (i.e. using micro data), the pursuit of this issue at the macro level (i.e. the level of the aggregate market) has remained largely unexplored. To that end, we jointly test for herding and feedback trading at the market level using data from the Portuguese market for the 1993-2005 period. Our results indicate the combined significant presence of herding and positive feedback trading for that period, with this significance exhibiting signs of clustering during the second half of the 1990s, which accommodated a series of boom-bust episodes for that market.
Experimental study of progressive breakdown in different conductance states of resistive switching structures

In this work, the breakdown transients of Al2O3- and HfO2-based metal-insulator-metal (MIM) stacks with the same oxide thickness and identical metal electrodes are studied. The differences and similarities between these transients in the progressive breakdown regime are assessed. Results show that Al2O3 exhibits longer breakdown transients than HfO2 and requires a higher voltage to initiate a very fast current runaway across the dielectric film. Similar results are observed when the devices are in remarkably different conductive states reached as a consequence of a resistive switching event. This suggests that both resistive switching and breakdown processes are linked to the thermal properties of the oxides under test rather than to dissipation effects occurring at the metal electrodes.
Mapping High-Resolution Surface Shortwave Net Radiation From Landsat Data

Maps of high-resolution surface shortwave net radiation (SSNR) are important for resolving differences in the surface energy budget at the ecosystem level. The maps can also bridge the gap between existing coarse-resolution SSNR products and point-based field measurements. This study presents a modified hybrid method to estimate both instantaneous and daily SSNR from Landsat data. SSNR values are directly linked to Landsat top-of-atmosphere reflectance by extensive radiative transfer simulation. Regression coefficients are pre-calculated and stored in a look-up table (LUT). Atmospheric water vapor is a key parameter affecting SSNR, and three methods of treating water vapor are evaluated in this study. Comparison between Landsat retrievals and field measurements at six AmeriFlux sites shows that the hybrid method with water vapor as a dimension of LUT can estimate SSNR with a root mean square error of 77.5 W/m2 (instantaneous) and 36.1 W/m2 (daily). The method of water vapor correction produces similar results. However, a generic LUT that covers all levels of water vapor results in much larger errors.
Structure-based design and experimental engineering of a plant virus nanoparticle for the presentation of immunogenic epitopes and as a drug carrier

Biomaterials research for the discovery of new generation nanoparticles is one of the most active areas of nanotechnoloy. In the search of nature-made nanometer-sized objects, plant virus particles appear as symmetrically defined entities that can be formed by protein self-assembly. In particular, in the field of plant virology, there is plenty of literature available describing the exploitation of plant viral cages to produce safe vaccine vehicles and nanoparticles for drug delivery. In this context, we have investigated on the use of the artichoke mottled crinkle virus (AMCV) capsid both as a carrier of immunogenic epitopes and for the delivery of anticancer molecules. A dual approach that combines both in silico tools and experimental virology was applied for the rational design of immunologically active chimeric virus-like particles (VLPs) carrying immunogenic peptides. The atomic structures of wild type (wt) and chimeric VLPs were obtained by homology modeling. The effects of insertion of the HIV-1 2F5 neutralizing epitope on the structural stability of chimeric VLPs were predicted and assessed by detailed inspection of the nanoparticle intersubunit interactions at atomic level. Wt and chimeric VLPs, exposing on their surface the 2F5 epitope, were successfully produced in plants. In addition, we demonstrated that AMCV capsids could also function as drug delivery vehicles able to load the chemotherapeutic drug doxorubicin. To our knowledge, this is the first systematic predictive and empirical research addressing the question of how this icosahedral virus can be used for the production of both VLPs and viral nanoparticles for biomedical applications.
