Novel Aspects of the Conduction Mechanisms of Electrolytes Containing Tetrahedral Moieties
Authors: Kendrick E. , Kendrick J. , Orera A. , Panchmatia P. , Islam M. S. , Slater P. R.
Published: September 2010

Traditionally materials with the fluorite and perovskite structures have dominated the research in the area of oxide ion/proton conducting solid electrolytes. In such cases, the key defects are oxide ion vacancies, and conduction proceeds via a simple vacancy hopping mechanism. In recent years, there has been growing interest in alternative structure types, many of which contain tetrahedral moieties. For these new systems, an understanding of the accommodation of defects and the nature of the conduction mechanism is important for the optimisation of their conductivities, as well as to help target related structures that may display high oxide ion/proton conduction. Computer modelling studies on a range of systems containing tetrahedral moieties are presented, including apatite‐type La9.33+xGe6O26+3x/2, cuspidine‐type La4Ga2–xTixO9+x/2 and La1–xBa1+xGaO4–x/2. The type of anion defect (vacancy or interstitial), their location and the factors affecting their incorporation are discussed. In addition, modelling data to help to understand their conduction mechanisms are presented, showing novel aspects including the important role of the tetrahedral moieties in the conduction processes.
Geostatistics for assessing the efficiency of a distributed physically‐based water quality model: application to nitrate in the Seine River
Authors: Polus Edwige , Flipo Nicolas , de Fouquet Chantal , Poulin Michel
Published: September 2010

This article shows how geostatistics can be used to reduce distributed physically based model (DPBM) uncertainties when assessing nitrate concentrations along a 250‐km stretch of the Seine River. First of all, co‐kriging is used to build a set of boundary conditions (BCs) (inlet concentrations from major tributary rivers) consistent with validation data. It partially addresses the issues of errors in data used as model input and errors in data to be compared with model outputs. Then the analysis of temporal variograms (simple variograms of observed and simulated concentrations, and their cross‐variogram) reveals a clear mismatch between simulated and observed values that was not detected by classical objective functions [root mean squared error (RMSE), etc.]. Variograms appear to include three components representing three different time scales: sub‐weekly, monthly and annual scales. Mismatches between simulated and observed values are analysed as (i) wrong quantification of inputs to the river (especially during the rainy period: combined sewer overflow (CSO), waste water treatment plant (WWTP) and tributary contributions to the nitrate fluxes in the Seine River) and (ii) wrong description of physical processes within the river. Finally, the modelling of simple and cross‐variograms appears to be a sensitive analysis tool which can be used to describe and reduce modelling uncertainties.

Assessment of future runoff trends under multiple climate change scenarios in the Willamette River Basin, Oregon, USA
Authors: Jung Il‐Won , Chang Heejun
Published: September 2010

We investigated trends in future seasonal runoff components in the Willamette River Basin (WRB) of Oregon for the twenty‐first century. Statistically downscaled climate projections by Climate Impacts Group (CIG), eight different global climate model (GCM) simulations with two different greenhouse gas (GHG) emission scenarios, (A1B and B1), were used as inputs for the US Geological Survey's Precipitation Runoff Modelling System. Ensemble mean results show negative trends in spring (March, April and May) and summer (June, July and August) runoff and positive trends in fall (September, October and November) and winter (December, January and February) runoff for 2000–2099. This is a result of temperature controls on the snowpack and declining summer and increasing winter precipitation. With temperature increases throughout the basin, snow water equivalent (SWE) is projected to decline consistently for all seasons. The decreases in the centre of timing and 7‐day low flows and increases in the top 5% flow are caused by the earlier snowmelt in spring, decreases in summer runoff and increases in fall and winter runoff, respectively. Winter runoff changes are more pronounced in higher elevations than in low elevations in winter. Seasonal runoff trends are associated with the complex interactions of climatic and topographic variables. While SWE is the most important explanatory variable for spring and winter runoff trends, precipitation has the strongest influence on fall runoff. Spatial error regression models that incorporate spatial dependence better explain the variations of runoff trends than ordinary least‐squares (OLS) multiple regression models. Our results show that long‐term trends of water balance components in the WRB could be highly affected by anthropogenic climate change, but the direction and magnitude of such changes are highly dependent on the interactions between climate change and land surface hydrology. This suggests a need for spatially explicit adaptive water resource management within the WRB under climate change. Copyright © 2010 John Wiley & Sons, Ltd.
On bandwidth selection for nonparametric estimation in flood frequency analysis
Authors: Quintela‐del‐Río A.
Published: September 2010

Nonparametric estimation of the distribution function of the annual maxima (AM) flood series is considered. In practice, the good behaviour of the nonparametric estimators depends heavily on the smoothing parameter or bandwidth. Nowadays, there exist only two (optimal under a mathematical point of view) bandwidth parameter selection methods in nonparametric distribution function estimation: cross‐validation and plug‐in. In this work, the cross‐validation procedure of Bowman et al. [Bowman A, Hall P, Prvan T. 1998. Bandwidth selection for the smoothing of distribution functions. Biometrika 85: 799‐808] is analysed. A simulation study checks the finite sample performance of the corresponding estimators, and a comparison of this method with a parametric procedure (the fitting of a extreme value distribution) is done with flow data of Salt River (AZ, USA). Along this work, we point out some common mistakes made in some papers dealing with statistical problems in hydrology, such as the use of the empirical distribution function instead of the observed data, or the bandwidth parameter selection by means of some method designed for nonparametric density estimation.

Recent studies on the application of microfabrication technologies for improving tribological properties
Authors: Nakano Miki , Ando Yasuhisa
Published: September 2010

The relationships between nanometer‐scale surface textures of periodic asperity arrays and friction force in unlubricated conditions and the relationships between micrometer‐scale surface textures of two‐tier structures and friction force in mixed lubrication conditions were investigated. The friction force and pull‐off force were measured on the asperity array in an unlubricated condition. Each force was proportional to the radius of the curvature of the asperity peak. The pull‐off force was determined by the Laplace pressure of the capillary condensed water. The friction force was measured on the micrometer‐scale surface textures of a two‐tier structure in lubricated conditions. The friction coefficient increased with higher bearing characteristic numbers at the higher B, though the friction coefficient was constant at the lower B. The roughness of the pin surface and the geometry of the two‐tier structure affected the friction coefficient at the lower B and higher B, respectively. Copyright © 2010 John Wiley & Sons, Ltd.
Cell‐cycle regulators cdk2ap1 and bicalutamide suppress malignant biological interactions between prostate cancer and bone cells
Authors: Zolochevska Olga , Figueiredo Marxa L.
Published: September 2010

INTRODUCTION

We examined whether the novel cell‐cycle regulator cdk2‐associated protein 1 (p12cdk2ap1 or cdk2ap1), recently shown to regulate prostate cancer cell cycle and apoptosis, could have the capacity to reduce invasiveness and/or reduce malignant biological interactions between prostate cancer and bone cells. We also examined whether combining two cell‐cycle arrest stimuli, cdk2ap1 plus bicalutamide (or casodex, CDX), could help enhance inhibition of prostate cancer cell phenotypes.

METHODS

We stably expressed cdk2ap1 in prostate cancer cell lines using lentiviral vectors, as well as several different co‐culture assays to quantify cellular invasion, migration, and the effect of the treatments on interaction with the bone microenvironment.

RESULTS

We have determined that cdk2ap1 can further augment the effects of CDX on cell‐cycle arrest, growth inhibition, and cellular invasion. Using a coculture model, we observed that either cdk2ap1 or cdk2ap1/CDX combination were able to reduce chemotaxis towards osteoblasts, and also reduce the osteoblastic proliferative response to prostate cancer. Also modified by cdk2ap1 and CDX were several signaling pathways associated with prostate cancer/bone crosstalk mechanisms involved in prostate cancer progression.

CONCLUSIONS

These results suggest that either cdk2ap1 or the cdk2ap1/CDX combination hold promise in regulating prostate cancer growth and malignant phenotypes, and potentially also in reducing procarcinogenic interactions with a bone microenvironment model, restoring malignant phenotypes and signaling to a more benign state.

Authors: Sahmay Sezai , Cetin Meral , Ocal Pelin , Kaleli Semih , Senol Hulya , Birol Fatih , Irez Tulay
Published: September 2010

Purpose

To evaluate the clinical value of day 3 serum anti‐Müllerian hormone (AMH) compared with day 3 serum follicle‐stimulating hormone (FSH) and human chorionic gonadotropin (hCG) day estradiol (E2) levels and antral follicle count (AFC) in the prediction of poor ovarian response in controlled ovarian hyperstimulation (COH).

Methods

AMH, FSH and AFC on day 3 as well as hCG day E2 levels were determined in 164 subjects. Receiver operating curve analyses and area under curves (AUC) of the study parameters were performed. Predictive values of the levels of day 3 AMH, FSH, AFC, and hCG day E2 as clinical parameters of ovarian response to COH were studied.

Results

Thirty‐eight women were defined as poor responders. The day 3 AMH and hCG day E2 levels and AFC of normal responders were significantly higher than those of the poor responders. In predicting poor response, the AUC of day 3 AMH level was significantly higher than that of day 3 FSH level but was similar to the hCG day E2 level. Day 3 AMH, FSH and hCG day E2 levels and AFC were found to predict a poor response. Day 3 AMH and hCG day E2 levels were more predictive compared with day 3 FSH level and AFC. The cut‐off level of AMH was ≤2 with a sensitivity of 78.9% and a specificity of 73.8%.

Conclusion

Day 3 AMH has the ability to predict a poor response to COH and it is more predictive than day 3 FSH and AFC.
Modulation of interferon signaling by hepatitis C virus non‐structural 5A protein: Implication of genotypic difference in interferon treatment
Authors: Kang Sang-Min , Won Seung-Jae , Lee Gun-Hee , Lim Yun-Sook , Hwang Soon B.
Published: September 2010

Interferon (IFN) response rate in hepatitis C virus (HCV) patients has been varied with genotypes. In this study, we investigated the effects of HCV NS5A protein on IFN resistance and compared the genotypic differences of NS5A. We showed that IFN‐α‐, poly I:C‐, and Sendai virus‐induced ISRE transcriptional activities were inhibited by both genotype 1b and 2a NS5A protein. We demonstrated that not only genotype 1b but also genotype 2a NS5A exerted the similar extent of IFN‐α‐induced antiviral activity. We showed that NS5A derived from both genotype 1b and 2a showed no significant differential IFN responses as seen in HCV patients. These data imply that some other host factor may be involved in genotypic differences of IFN antagonism in HCV patients.
The Congressman's Civil War
Authors: Bogue Allan G.
Published: September 2010

In the historical literature of the American Civil War, the president, the generals, and the cabinet secretaries have won the war of words. Of the hundreds of men who served in the House of Representative during this great struggle, only a handful appear typically in general discussions of the period. Yet without a deeper understanding of the contributions of the members of Congress to the successful prosecution of the war we cannot fully appreciate the desperate nature of that conflict and its significance in the building of the nation. This book explores important aspects of the Civil War from the perspective of Capital Hill. It is an effort to reconnoiter some of the possibilities for understanding the congressmen, their relations with one another, and their interaction with President Lincoln. Designed as an exploration rather than as a full-scale history of the Civil War Congress, this book reveals a legislature in which the average length of service was very short, although a relatively small core of national public figures provide continuity. The era was one of strong ideology and fateful policy decisions, but the congressmen continued to think also as politicians. The author suggests that not one but many political agendas were at issue in Congress during the Civil War. The Republicans had significant success in achieving the goals represented by their national platform of 1860, but the necessity of developing an ad hoc wartime agenda resulted in major struggles between party leaders and between elements in Congress and in party caucuses, as well as between the legislative and executive branches. In such activity neither the president nor any particular congressional group was the clear victor, and the war ended with momentous issues still undecided. While public attention focused on such issues and great armies marched to victory or disaster, the federal lawmakers fulfilled their institutional roles to their own best advantages and thought in terms of patronage, personal power, and career advancement.

Introductory Studies in Greek Art
Authors: Harrison Jane Ellen
Published: September 2010

Jane Ellen Harrison (1850–1928) was a prominent classical scholar who is remembered chiefly for her influential studies of Greek religion, archaeology, literature and art. Introductory Studies in Greek Art (1885) was Harrison's second book, published after a period spent studying archaeology at the British Museum under Sir Charles Newton and writing and lecturing on the subject of Greek vase painting. In her preface to the book Harrison claims that Greek art is distinguished by what she calls 'ideality', a term she defines as a 'peculiar quality ... which adapts itself to the consciousness of successive ages ... a certain largeness and universality which outlives the individual race and persists for all time.' The book covers topics including Chaldaeo-Assyria, Phoenicia, Pheidias and the Parthenon, and the altar of Eumenes at Pergamos.
Australian Aborigines
Authors: Dawson James
Published: September 2010

James Dawson first published Australian Aborigines in 1881, after deciding that his careful description of the tribes, languages, customs, and characteristics of the indigenous peoples of the western district of Victoria was too bulky for its originally intended publication in a newspaper. Essentially a field-inspired anthropological account of the dwindling Aboriginal population, written before the emergence of anthropology as a formal discipline, Dawson's book draws on his daughter's ability to speak the local languages and attempts a balanced description of a culture he considered ill-used and under-appreciated by white settlers. Minute details about clothing, tools, settlement and beliefs combine to depict a complex society that possessed highly ritualised customs deserving of respect. Dawson also included an extensive vocabulary of words in three indigenous languages that he hoped would facilitate further cross-cultural understanding. His work provides valuable source material for modern researchers in anthropology and linguistics.
Bentley
Authors: Jebb R. C.
Published: September 2010

First published in 1882, this is a biography of the English clergyman, scholar and classicist, Richard Bentley (1662–1742). Born in West Yorkshire, educated at Wakefield Grammar School and later at St John's College in Cambridge, Bentley became one of the most respected textual critics of his day. Among students of the Greek New Testament, he is remembered as the first person to define a plan for constructing the whole of the text directly from the original documents. Bentley became a prominent and controversial figure during his time as Master of Trinity College, Cambridge. His temper and his contemptuous treatment of his colleagues led to various attempts to secure his removal and embroiled him in controversy and feuding for the next 30 years. Despite all this, Bentley continued his classical research and published books that are studied to this day.
Cancer of the Esophagus
Authors: Craddock Valda M.
Published: September 2010

The book deals briefly with the normal structure, functioning and biochemistry of the esophagus and with the histological and genetic changes accompanying the development of esophageal cancer in humans and animals. Factors implicated in causing esophageal cancer are described in relation to its very dramatic epidemiology. Thus dietary deficiencies and consumption of foods contaminated by Fusaria mycotoxins are discussed in connection with the extremely high incidence of the disease in certain sharply demarcated regions in China and South Africa, and alcohol and tobacco use are discussed in relation to the epidemiology in Europe and USA. Other hazards mentioned include opium in Iran, betel nut in Asia and bracken in Japan. The sole group of chemicals known to be very potent esophageal carcinogens in animal experiments, the nitrosamines, are described especially in terms of the widespread human exposure.
Regime Type, the Fate of Leaders, and War
Authors: DEBS ALEXANDRE , GOEMANS H.E.
Published: September 2010

We propose and test a formal model of war and domestic politics, building on recent evidence on the relationship between regime type, the effect of war on the probability of losing office, and the consequences of losing office. The less the outcome of international interaction affects a leader's tenure and the less punitive are the consequences of losing office, the more a leader is willing to make concessions to strike a peaceful bargain. We demonstrate that our theory successfully predicts war involvement among nondemocratic regime types. Moreover, our theory offers an intuitive explanation for the democratic peace. Compared to nondemocratic leaders, the tenure of democratic leaders depends relatively little on the war outcome, and democratic leaders fare relatively well after losing office. Thus, democratic leaders should be more willing and able to avoid war, especially with other democrats.
Redox-modulatory vitamins and minerals that prospectively predict mortality in older British people: the National Diet and Nutrition Survey of people aged 65 years and over
Authors: Bates Christopher J. , Hamer Mark , Mishra Gita D.
Published: September 2010

The predictive power, for total, vascular, cancer and respiratory mortality, of selected redox-modulatory (vitamin and mineral nutrient) indices measured at baseline, was studied in the British National Diet and Nutrition Survey (community-living subset) of people aged 65 years and over. Mortality status and its primary and underlying causes were recorded for 1054 (mean age 76·6 (sd 7·4) years and 49·0 % female) participants, from the baseline survey in 1994–5 until September 2008. During this interval, 74 % of the male and 62 % of the female participants died. Total mortality was significantly predicted by baseline plasma concentrations (per sd) of vitamin C (hazard ratio (HR) 0·81; 95 % CI 0·74, 0·88), α-carotene (HR 0·90; 95 % CI 0·81, 0·99), Se (HR 0·76; 95 % CI 0·69, 0·84), Zn (HR 0·79; 95 % CI 0·72, 0·87), Cu (HR 1·27; 95 % CI 1·14, 1·42) and Fe (HR 0·81; 95 % CI 0·74, 0·89). Total mortality was also significantly predicted by baseline dietary intakes (per sd) of food energy (HR 0·86; 95 % CI 0·79, 0·94), vitamin C (HR 0·88; 95 % CI 0·80, 0·94), carotenoids (HR 0·89; 95 % CI 0·83, 0·96), Zn (HR 0·89; 95 % CI 0·82, 0·96) and Cu (HR 0·91; 95 % CI 0·84, 1·00). Prediction patterns and significance for primary vascular, cancer and respiratory mortality differed in certain respects, but not fundamentally. Model adjustment for known disease or mortality risk predictors resulted in loss of significance for some of the indices; however, plasma Se and Zn, and food energy remained significant predictors. We conclude that total and primary vascular, cancer and respiratory mortality in older British people of both sexes is predicted by several biochemical indices of redox-modulatory nutrients, some of which may reflect the respondents' acute-phase status at baseline, whereas others may reflect the healthiness of their lifestyle.
Red meat from animals offered a grass diet increases plasma and plateletn-3 PUFA in healthy consumers

Red meat from grass-fed animals, compared with concentrate-fed animals, contains increased concentrations of long-chain (LC)n-3 PUFA. However, the effects of red meat consumption from grass-fed animals on consumer blood concentrations of LCn-3 PUFA are unknown. The aim of the present study was to compare the effects on plasma and platelet LCn-3 PUFA status of consuming red meat produced from either grass-fed animals or concentrate-fed animals. A randomised, double-blinded, dietary intervention study was carried out for 4 weeks on healthy subjects who replaced their habitual red meat intake with three portions per week of red meat (beef and lamb) from animals offered a finishing diet of either grass or concentrate (n20 consumers). Plasma and platelet fatty acid composition, dietary intake, blood pressure, and serum lipids and lipoproteins were analysed at baseline and post-intervention. Dietary intakes of totaln-3 PUFA, as well as plasma and platelet concentrations of LCn-3 PUFA, were significantly higher in those subjects who consumed red meat from grass-fed animals compared with those who consumed red meat from concentrate-fed animals (P < 0·05). No significant differences in concentrations of serum cholesterol, TAG or blood pressure were observed between groups. Consuming red meat from grass-fed animals compared with concentrate-fed animals as part of the habitual diet can significantly increase consumer plasma and platelet LCn-3 PUFA status. As a result, red meat from grass-fed animals may contribute to dietary intakes of LCn-3 PUFA in populations where red meat is habitually consumed.
Petrogenesis and tectonic evolution of metaluminous sub-alkaline granitoids from the Takab Complex, NW Iran

Published: September 2010

The Takab complex is composed of a variety of metamorphic rocks including amphibolites, metapelites, mafic granulites, migmatites and meta-ultramafics, which are intruded by the granitoid. The granitoid magmatic activity occurred in relation to the subduction of the Neo-Tethys oceanic crust beneath the Iranian crust during Tertiary times. The granitoids are mainly granodiorite, quartz monzodiorite, monzonite and quartz diorite. Chemically, the magmatic rocks are characterized by ASI<1.04, AI<0.87 and high contents of CaO (up to ~14.5 wt%), which are consistent with the I-type magmatic series. Low FeOt/(FeOt+MgO) values (<0.75) as well as low Nb, Y and K2O contents of the investigated rocks resemble the calc-alkaline series. Low SiO2, K2O/Na2O and Al2O3accompanied by high CaO and FeO contents indicate melting of metabasites as an appropriate source for the intrusions. Negative Ti and Nb anomalies verify a metaluminous crustal origin for the protoliths of the investigated igneous rocks. These are comparable with compositions of the associated mafic migmatites, in the Takab metamorphic complex, which originated from the partial melting of amphibolites. Therefore, crustal melting and a collision-related origin for the Takab calc-alkaline intrusions are proposed here on the basis of mineralogy and geochemical characteristics. TheP–Tevolution during magmatic crystallization and subsolidus cooling stages is determined by the study of mineral chemistry of the granodiorite and the quartz diorite. Magmatic crystallization pressure and temperature for the quartz-diorite and the granodiorite are estimated to beP~7.8±2.5 kbar,T~760±75°C andP~5±1 kbar,T~700°C, respectively. Subsolidus conditions are consistent with temperatures of ~620°C and ~600°C, and pressures of ~5 kbar and ~3.5 kbar for the quartz-diorite and the granodiorite, respectively.
Small-scale spatial variability of zoobenthic communities in a commercial Mediterranean port
Authors: Antoniadou Chryssanthi , Sarantidis Sarantis , Chintiroglou Chariton
Published: September 2010

In the context of the limited information on the ecology of port communities, the present work aims at assessing the small-scale spatial variability of zoobenthos inhabiting hard and soft substrata, in a Mediterranean port with high levels of commercial shipment. Samples were collected in summer from three stations and four depth levels, using core and quadrate samplers. A total of 34,578 individuals were collected, identified to 118 animal species. Soft substratum communities were impoverished and their structure varied spatially according to sediment composition. At a functional level deposit feeders dominated; their abundance decreased at the silty sites. Biotic indices were found inadequate for the assessment of ecological quality, due to the very low abundance of the fauna. Fouling communities varied spatially in vertical scales; diversity indices and the abundance of Bivalvia varied also in horizontal scales. Suspension and deposit feeders dominated showing a decreasing trend with depth. Two animal-dominated communities, serpulid blocks in the lower midlittoral zone and mussel beds in the sublittoral, substituted an algal-dominated community, which has been previously recorded from the same port quays. This substitution may be due to the intensive mussel farming in the nearby area contributing to the rapid expansion of mussels and of their serpulid biofoulers. Despite the existence of biogenic substrata, which enhance habitat complexity, the diversity of the associated fauna decreased and most species were tolerant to organic pollution. Recursive biomonitoring seems necessary to assess the ecological status of communities and to develop integrated management plans for temperate ports.
Age and growth of adult gilthead seabream (Sparus aurata L.) in the Aegean Sea
Authors: Akyol Okan , Gamsiz Kutsal
Published: September 2010

Age and growth of adult gilthead seabream, Sparus aurata were determined from 332 specimens (total N = 476), collected from purse-seiners, in the south-eastern Aegean Sea from November 2006 to January 2007. The fork length and body wet weight ranged from 26.5 to 51.5 cm (mean: 36.6 ± 0.18) and from 375 to 2600 g (mean: 1009.2 ± 14.16), respectively. Age groups were varied between 2 and 7. Growth parameters were estimated as L∞ = 64.97 ± 12.93 cm, K = 0.14 ± 0.07 year−1, t0 = −2.47 ± 1.09 year−1, and index of phi-prime was Φ′ = 2.772 ± 0.51. The length–weight relationship equation of all fish was calculated as W = 0.0515 × L2.737 (r2 = 0.95). The mean condition factor was estimated as 2.058. Mortalities (M, F and Z) and exploitation rate (E) of gilthead seabream from the Aegean Sea were 0.34 year−1, 0.77 year−1, 1.11 year−1and 0.69 year−1, respectively. The result of E indicated that the population was overexploited.
Structural changes of gonads during artificially induced gametogenesis and spawning in the giant jellyfish Nemopilema nomurai (Scyphozoa: Rhizostomeae)
Authors: Ikeda Hideki , Ohtsu Kohzoh , Uye Shin-Ichi
Published: September 2010

We conducted a histological investigation of the ovaries and testes during the gametogenesis and spawning in the giant jellyfish Nemopilema nomurai, which has bloomed in East Asian marginal seas almost annually since 2002. Oocytes arising from the ovarian epithelium make intimate contact with special epithelial cells, called trophocytes, which have microvilli on the subgenital sinus side, Golgi complexes and vesicles in the cytoplasm. In the early vitellogenic stage, yolk bodies occur in the ooplasm adjacent to the trophocytes, suggesting that the trophocytes transfer nutrients from the subgenital sinus to the oocyte. Later, yolk bodies are formed by the Golgi complexes in the entire ooplasm and accumulate until the oocyte matures. In the late vitellogenic stage, the oocyte separates from the trophocytes and forms microvilli on its surface, indicating nutrient uptake from the surrounding mesoglea. Nutrient support from the trophocytes in the early vitellogenic stage may make the oocytes mature rapidly after medusae are physically damaged. Microvilli-rich epithelial cells also associate with sperm follicles where spermatocytes arise from the follicle cells and accumulate, but their function in nutrient uptake is possibly less than that of trophocytes according to their morphology. During ovulation, which takes 1.5 hours after light exposure, trophocytes separate from each other and make an ovulation pit where the oocyte passes out to the subgenital sinus with the surrounding basal lamina. Spermiation occurs 5–20 minutes after light exposure, and spermatozoa are liberated through the spermiation pit that was formed by which the microvilli-rich cells dissociate. The trophocytes in ovaries and microvilli-rich cells in testes have important roles not only in the gametogenesis but also in the spawning of N. nomurai.
The evolution of international law in light of the ‘global War on Terror’
Authors: HEINZE ERIC A.
Published: September 2010

This article explores how various aspects of the ‘global War on Terror’ may be affecting the future development of international law on the use of force. I examine these effects within three areas of international law – the law of anticipatory self-defence, the law of self-defence against non-state actors, and the applicability of international humanitarian law to non-state armed groups. Only in the latter two areas do I find evidence that international law is evolving to accommodate the new realities of global terror. While such developments in the law reflect the supposed need by states to use military means to combat terrorism, they also seem to confer at least a limited international legal personality upon terrorist groups such asAl-Qaeda. This not only indicates a shift in the basis for legal personality, but also potentially undermines the legitimacy of international law and frustrates states' efforts at combating terrorism.
Interface conditions on postverbal subjects: A corpus study of L2 English
Authors: LOZANO CRISTÓBAL , MENDIKOETXEA AMAYA
Published: September 2010

This paper investigates how syntactic knowledge interfaces with other cognitive systems by analysing the production of postverbal subjects, V(erb)–S(ubject) order, in an L1 Spanish–L2 English corpus and a comparable English native corpus. VS order in both native and L2 English is shown to be constrained by properties operating at three interfaces: (i)lexicon–syntax: the verb is unaccusative (Unaccusative Hypothesis); (ii)syntax–discourse: the subject is focus (End-Focus Principle) and (iii)syntax–phonology: the subject is heavy (End-Weight Principle). We show that, since learners produce VS under the same interface conditions as native speakers, unaccusativity is a necessary but not a sufficient condition for VS production. However, learners overproduce VS and make persistent errors in their syntactic encoding. Our findings support recent proposals that these difficulties stem from problems at coordinating syntactic knowledge with knowledge from other external systems, but they suggest that the nature of such difficulties is not external to the syntax.
Local quaternionic rigidity for complex hyperbolic lattices
Authors: Kim Inkang , Klingler Bruno , Pansu P.
Published: September 2010

Let $\smash{\sGa\stackrel{i}{\hookrightarrow}L}$ be a lattice in the real simple Lie group L. If L is of rank at least 2 (respectively locally isomorphic to Sp(n, 1)) any unbounded morphism ρ : Γ → G into a simple real Lie group G essentially extends to a Lie morphism ρL : L → G (Margulis's superrigidity theorem, respectively Corlette's theorem). In particular any such morphism is infinitesimally, thus locally, rigid. On the other hand, for L = SU(n, 1) even morphisms of the form $\smash{\rho:\sGa\stackrel{i}{\hookrightarrow}L \rightarrow G}$ are not infinitesimally rigid in general. Almost nothing is known about their local rigidity. In this paper we prove that any cocompact lattice Γ in SU(n, 1) is essentially locally rigid (while in general not infinitesimally rigid) in the quaternionic groups Sp(n, 1), SU(2n, 2) or SO(4n, 4) (for the natural sequence of embeddings SU(n, 1) ⊂ Sp(n, 1) ⊂ SU(2n, 2) ⊂ SO(4n, 4)).

Dying of corruption
Authors: Holmberg Sören , Rothstein Bo
Published: September 2010

In many poor countries, over 80% of the population have experienced corrupt practices in the health sector. In rich countries, corruption takes other forms such as overbilling. The causal link between low levels of the quality of government (QoG) and population health can be either direct or indirect. Using cross-sectional data from more than 120 countries, our findings are that more of a QoG variable is positively associated with higher levels of life expectancy, lower levels of mortality rates for children and mothers, higher levels of healthy life expectancies and higher levels of subjective health feelings. In contrast to the strong relationships between the QoG variables and the health indicators, the relationship between the health-spending measures and population health are rather weak most of the time and occasionally non-existent. Moreover, for private health spending as well as for private share of total health spending, the relation to good health is close to zero or slightly negative. The policy recommendation coming out of our study to improve health levels around the world, in rich countries as well as in poor countries, is to improve the QoG and to finance health care with public, not private, money.
Effects of snow cover on soil freezing, water movement, and snowmelt infiltration: A paired plot experiment

A dramatic reduction in soil frost depth has been reported for Hokkaido Island of northern Japan over the last 20 years. Since soil frost strongly affects snowmelt infiltration and runoff, the reduction in frost depth may have altered the water and nutrient cycles in this region. A paired‐plot experiment was conducted in an agricultural field in Tokachi, Hokkaido, to compare the movement of soil water at different frost depths, controlled by manipulating the depth of snow cover. Snow was removed to enhance soil freezing in the treatment plot and was undisturbed in the control plot. The soil froze to a maximum depth of 0.43 m under the treatment plot and 0.11 m under the control plot. During the freezing period, the amount of upward soil water flux toward the freezing front in the treatment plot was more than double that in the control plot. During the snowmelt period, infiltration of meltwater was unimpeded by the thin frozen layer in the control plot, whereas the relatively thick frozen layer in the treatment plot impeded infiltration and generated 63 mm of runoff. These results clearly show that the changes in the timing and thickness of snow cover deposition can cause a dramatic reduction of frost depth and change in the soil water dynamics.

This paper reports on a magnetotelluric (MT) survey across the central Mariana subduction system, providing a comprehensive electrical resistivity image of the upper mantle to address issues of mantle dynamics in the mantle wedge and beneath the slow back‐arc spreading ridge. After calculation of MT response functions and their correction for topographic distortion, two‐dimensional electrical resistivity structures were generated using an inversion algorithm with a smoothness constraint and with additional restrictions imposed by the subducting slab. The resultant isotropic electrical resistivity structure contains several key features. There is an uppermost resistive layer with a thickness of up to 150 km beneath the Pacific Ocean Basin, 80–100 km beneath the Mariana Trough, and 60 km beneath the Parece Vela Basin along with a conductive mantle beneath the resistive layer. A resistive region down to 60 km depth and a conductive region at greater depth are inferred beneath the volcanic arc in the mantle wedge. There is no evidence for a conductive feature beneath the back‐arc spreading center. Sensitivity tests were applied to these features through inversion of synthetic data. The uppermost resistive layer is the cool, dry residual from the plate accretion process. Its thickness beneath the Pacific Ocean Basin is controlled mainly by temperature, whereas the roughly constant thickness beneath the Mariana Trough and beneath the Parece Vela Basin regardless of seafloor age is controlled by composition. The conductive mantle beneath the uppermost resistive layer requires hydration of olivine and/or melting of the mantle. The resistive region beneath the volcanic arc down to 60 km suggests that fluids such as melt or free water are not well connected or are highly three‐dimensional and of limited size. In contrast, the conductive region beneath the volcanic arc below 60 km depth reflects melting and hydration driven by water release from the subducting slab. The resistive region beneath the back‐arc spreading center can be explained by dry mantle with typical temperatures, suggesting that any melt present is either poorly connected or distributed discontinuously along the strike of the ridge. Evidence for electrical anisotropy in the central Mariana upper mantle is weak.
A multiscale approach to estimating topographically correlated propagation delays in radar interferograms

Published: September 2010

When targeting small amplitude surface deformation, using repeat orbit Interferometric Synthetic Aperture Radar (InSAR) observations can be plagued by propagation delays, some of which correlate with topographic variations. These topographically‐correlated delays result from temporal variations in vertical stratification of the troposphere. An approximate model assuming a linear relationship between topography and interferometric phase has been used to correct observations with success in a few studies. Here, we present a robust approach to estimating the transfer function, K, between topography and phase that is relatively insensitive to confounding processes (earthquake deformation, phase ramps from orbital errors, tidal loading, etc.). Our approach takes advantage of a multiscale perspective by using a band‐pass decomposition of both topography and observed phase. This decomposition into several spatial scales allows us to determine the bands wherein correlation between topography and phase is significant and stable. When possible, our approach also takes advantage of any inherent redundancy provided by multiple interferograms constructed with common scenes. We define a unique set of component time intervals for a given suite of interferometric pairs. We estimate an internally consistent transfer function for each component time interval, which can then be recombined to correct any arbitrary interferometric pair. We demonstrate our approach on a synthetic example and on data from two locations: Long Valley Caldera, California, which experienced prolonged periods of surface deformation from pressurization of a deep magma chamber, and one coseismic interferogram from the 2007 Mw 7.8 Tocapilla earthquake in northern Chile. In both examples, the corrected interferograms show improvements in regions of high relief, independent of whether or not we pre‐correct the data for a source model. We believe that most of the remaining signals are predominately due to heterogeneous water vapor distribution that requires more sophisticated correction methods than those described here.
Functional Performance Using Eye Control and Single Switch Scanning by People With ALS
Authors: Gibbons Chris , Beneteau Erin
Published: September 2010

Eye control and switch scanning are commonly considered as augmentative and alternative communication (AAC) access options by people with amyotrophic lateral sclerosis (ALS) at the same clinical intervention point. Choosing optimal access methods must be supported by performance and qualitative feedback, as well as considerations of cognitive changes sometimes associated with ALS. We present quantitative and qualitative data comparing access methods used by five people with ALS and five adults without ALS. Each participant accessed an on-screen keyboard during repeated exposure to two conditions: single switch scanning and eye control. Participants were required to copy sentences presented on a computer screen. Keyboard letter organization was held constant between conditions, and rate enhancement and word prediction techniques were not used. Measures of speed and accuracy revealed a significant speed advantage for eye control and a significant accuracy advantage for single switch scanning. Speed and accuracy for both access methods improved with practice. Predictably, people with ALS performed significantly slower than participants without ALS using both access methods. Participants rated eye control as the more efficient access method overall. Participants without ALS rated both access methods significantly more fatiguing than people with ALS. Post study interviews revealed that eye control was the preferred access option for people with ALS. Clinical implications and extensions of this study are discussed.
Atomistic modeling of nanoscale patterning of L12 order induced by ion irradiation

Published: September 2010

Theoretical predictions indicate that ordered alloys can spontaneously develop a steady-state nanoscale microstructure when irradiated with energetic particles. This behavior derives from a dynamical competition between disordering in cascades and thermally activated reordering, which leads to self-organization of the chemical order parameter. We test this possibility by combining molecular dynamics (MD) and kinetic Monte Carlo (KMC) simulations. We first generate realistic distributions of disordered zones for Ni3Al irradiated with 70 keV He and 1 MeV Kr ions using MD and then input this data into KMC to obtain predictions of steady state microstructures as a function of the irradiation flux. Nanoscale patterning is observed for Kr ion irradiations but not for He ion irradiations. We illustrate, moreover, using image simulations of these KMC microstructures, that high-resolution transmission electron microscopy can be employed to identify nanoscale patterning. Finally, we indicate how this method could be used to synthesize functional thin films, with potential for magnetic applications.

TlInGaAsN/TlGaAsN system was proposed to fabricate the temperature-insensitive both lasing wavelength and threshold current density laser diodes, which are important in the wavelength division multiplexing optical fiber communication system. The effects of indium and nitrogen concentrations in the quantum wells (QWs) and barriers on the properties of molecular-beam epitaxy grown TlInGaAsN/TlGaAsN triple QWs (TQWs) were investigated. The TQW samples having higher N concentration in the QWs have the highest Tl incorporation without deterioration of the crystalline quality. The temperature dependence of the photoluminescence (PL) peak energy was found to be the least for the highest Tl containing TQW sample. The incorporation of Tl causes the reduction in the coupling constant of the electron–phonon interaction, leading to the reduced temperature dependence of the PL peak shift. Thermal activation energies, which are deduced from the Arrhenius plot of PL intensity, are attributed to the delocalization of the excitons at low temperatures and to the escape of carriers from the QWs to the barriers at high temperatures.
Tunable dual-frequency oscillators of carbon nanotubes
Authors: Li Bin , Chang Tienchong
Published: September 2010

We propose a carbon nanotube oscillator that is composed of a cantilever inner tube and a short outer tube. When the inner tube vibrates, the centrifugal force and the van der Waals force drive the outer tube to oscillate along the inner tube, which means that the oscillator can simultaneously output two frequencies. The operation frequencies of the oscillator may be tunable in a wide range (from tens of gigahertz to more than 100 GHz) by controlling the initial conditions. The combination of tunability and high-frequency operation makes the oscillators promising for a variety of scientific and technological applications. A continuum model is presented to study the frequency properties of the oscillator. The model is validated by the molecular dynamics simulations.
