Structures of water molecules in carbon nanotubes under electric fields
Authors: Winarto  , Takaiwa Daisuke , Yamamoto Eiji , Yasuoka Kenji
Published: March 2015

Carbon nanotubes (CNTs) are promising for water transport through membranes and for use as nano-pumps. The development of CNT-based nanofluidic devices, however, requires a better understanding of the properties of water molecules in CNTs because they can be very different from those in the bulk. Using all-atom molecular dynamics simulations, we investigate the effect of axial electric fields on the structure of water molecules in CNTs having diameters ranging from (7,7) to (10,10). The water dipole moments were aligned parallel to the electric field, which increases the density of water inside the CNTs and forms ordered ice-like structures. The electric field induces the transition from liquid to ice nanotubes in a wide range of CNT diameters. Moreover, we found an increase in the lifetime of hydrogen bonds for water structures in the CNTs. Fast librational motion breaks some hydrogen bonds, but the molecular pairs do not separate and the hydrogen bonds reform. Thus, hydrogen bonds maintain the water structure in the CNTs, and the water molecules move collectively, decreasing the axial diffusion coefficient and permeation rate.

Authors: Jagannadh Veerendra Kalyan , Srinivasan Rajesh , Gorthi Sai Siva
Published: March 2015

Clinical microscopy is a versatile diagnostic platform used for diagnosis of a multitude of diseases. In the recent past, many microfluidics based point-of-care diagnostic devices have been developed, which serve as alternatives to microscopy. However, these point-of-care devices are not as multi-functional and versatile as clinical microscopy. With the use of custom designed optics and microfluidics, we have developed a versatile microscopy-based cellular diagnostic platform, which can be used at the point of care. The microscopy platform presented here is capable of detecting infections of very low parasitemia level (in a very small quantity of sample), without the use of any additional computational hardware. Such a cost-effective and portable diagnostic device, would greatly impact the quality of health care available to people living in rural locations of the world. Apart from clinical diagnostics, it’s applicability to field research in environmental microbiology has also been outlined.

High-throughput screening has been widely utilized in the pharmaceutical and manufacturing industry targeting the development of new molecules and materials for numerous applications. To enable more rapid progress in photocatalytic water-splitting reactions, the construction of high-throughput combinatorial photoreactors enabling the parallel optimization of relevant compositions under varieties of experimental conditions seems appropriate. This contribution describes a 16-photoreactor apparatus permitting the kinetic evaluation of photocatalytic gas-producing reactions using head-space pressure, gas chromatography, and mass spectrometry operating in parallel, illustrated with molecular-based homogeneous photocatalytic H2-generating compositions.
A fluid model simulation of a simplified plasma limiter based on spectral-element time-domain method
Authors: Qian Cheng , Ding Dazhi , Fan Zhenhong , Chen Rushan
Published: March 2015

A simplified plasma limiter prototype is proposed and the fluid model coupled with Maxwell's equations is established to describe the operating mechanism of plasma limiter. A three-dimensional (3-D) simplified sandwich structure plasma limiter model is analyzed with the spectral-element time-domain (SETD) method. The field breakdown threshold of air and argon at different frequency is predicted and compared with the experimental data and there is a good agreement between them for gas microwave breakdown discharge problems. Numerical results demonstrate that the two-layer plasma limiter (plasma-slab-plasma) has better protective characteristics than a one-layer plasma limiter (slab-plasma-slab) with the same length of gas chamber.
Non-resonant elastic scattering of low-energy photons by atomic sodium confined in quantum plasmas
Authors: Ghosh Avijit , Ray Debasis
Published: March 2015

The non-resonant elastic scattering of low-energy photons by the bound valence electron in the ground state 3s of atomic sodium confined in quantum plasmas is investigated theoretically. The incident photon energy is assumed to be much smaller than the 3s-3p excitation energy. The alkali atom sodium is first formulated as an effective one-electron problem in which the attractive interaction between the valence electron and the atomic ion core is simulated by a spherically symmetric model potential. The Shukla-Eliasson oscillatory exponential cosine screened-Coulomb potential model is then used to mimic the effective two-body (valence-core) interaction within quantum plasmas. Non-relativistic calculations performed within the electric dipole approximation indicate that the non-resonant elastic photon scattering cross-section undergoes a dramatic growth by several orders of magnitude as the quantum wave number increases. A qualitative explanation of this phenomenon is presented. In the absence of the oscillatory cosine screening term, a similar growth is observed at larger values of the quantum wave number. Our computed relevant atomic data are in very good agreement with the experimental as well as the previous theoretical data for the zero-screening (free atom) case, and with the very limited, accurate theoretical results available for the case of exponential screened-Coulomb two-body interaction, without the cosine screening term.
Nonlinear effects in a model of a thermoacoustic refrigerator driven by a loudspeaker
Authors: Fan Li , Chen Zhe , Zhu Jun-jie , Ding Jin , Xia Jie , Zhang Shu-yi , Zhang Hui , Ge Huan
Published: March 2015

It is known that acoustic nonlinear effects in thermoacoustic refrigerators are unfavorable to the performance because they transfer the acoustic energy of the fundamental wave to harmonic waves, while only the former is useful for refrigeration. To study the nonlinear effects in loudspeaker-drive thermoacoustic refrigerators, we measure the acoustic performance in a coupling system composed of a resonant pipe driven by an electrodynamic loudspeaker via an inverse horn. It is found that the nonlinear effects increase both the acoustic pressure of fundamental wave in the resonant pipe and the electroacoustic transfer efficiency of the system. Then, a theoretical model is established to study the nonlinear effects in the coupling system, in which the nonlinearities arising from the loudspeaker, inverse horn, and resonant pipe are taken into account, and the simulated results are used to explain the experimental phenomena.
Deuterium absorption from the D2O exposure of oxidized 4H-SiC (0001), (0001¯), and (112¯) surfaces
Authors: Liu Gang , Xu Can , Yakshinskiy Boris , Wielunski Leszek , Gustafsson Torgny , Bloch Joseph , Dhar Sarit , Feldman Leonard C.
Published: March 2015

We report results on deuterium absorption on several oxidized 4H-SiC surfaces following D2O vapor absorption. Absorption at the oxide/semiconductor interface is strongly face dependent with an order of magnitude more deuterium on the C-face and a-face than on the Si-face, in contrast to the bulk of the oxides which show essentially no face dependence. Annealing in NO gas produces a large reduction in interfacial deuterium absorption in all cases. The reduction of the positive charge at the interface scales linearly with the interface D content. These results also scale with the variation in interface trap density (Dit) and mobility on the three faces after wet oxidation annealing.
Site-specific probing of charge transfer dynamics in organic photovoltaics
Authors: Arion Tiberiu , Neppl Stefan , Roth Friedrich , Shavorskiy Andrey , Bluhm Hendrik , Hussain Zahid , Gessner Oliver , Eberhardt Wolfgang
Published: March 2015

We report the site-specific probing of charge-transfer dynamics in a prototype system for organic photovoltaics (OPVs) by picosecond time-resolved X-ray photoelectron spectroscopy. A layered system consisting of approximately two monolayers of C60 deposited on top of a thin film of Copper-Phthalocyanine (CuPC) is excited by an optical pump pulse and the induced electronic dynamics are probed with 590 eV X-ray pulses. Charge transfer from the electron donor (CuPC) to the acceptor (C60) and subsequent charge carrier dynamics are monitored by recording the time-dependent C 1s core level photoemission spectrum of the system. The arrival of electrons in the C60 layer is readily observed as a completely reversible, transient shift of the C60 associated C 1s core level, while the C 1s level of the CuPC remains unchanged. The capability to probe charge transfer and recombination dynamics in OPV assemblies directly in the time domain and from the perspective of well-defined domains is expected to open additional pathways to better understand and optimize the performance of this emerging technology.
Live fuel moisture content and leaf ignition of forest species in Andean Patagonia, Argentina
Authors: Bianchi Lucas O. , Defossé Guillermo E.
Published: March 2015

Wildfires are common from summer to early fall in Patagonian forests of Argentina. Live fuel moisture content (LFMC) and leaf ignition are important factors for understanding fire behaviour. In this study, we determined seasonal LFMC and leaf ignition of some key fire-prone species of these forests, and their relationships with environmental variables. Species investigated were the native trees ñire (Nothofagus antarctica) and cypress (Austrocedrus chilensis), the understorey tree-like radal (Lomatia hirsuta) and laura (Schinus patagonicus), the bamboo caña colihue (Chusquea culeou), and the non-native black poplar (Populus nigra). LFMC differed among species, with caña colihue having lower values (LFMC <100%); ñire, laura, cypress, and radal having medium values (110–220%); and black poplar, upper values (>220%). Ignition characteristics differed among species (caña colihue > ñire > radal > cypress > laura > black poplar) and were inversely related to LFMC. Correlations between LFMC and environmental variables were highly significant for caña colihue, significant for ñire, radal, and laura, and weakly significant or non-significant for cypress and black poplar. These results contribute to our understanding of fire behaviour, and validate the fuel typology for Patagonian forests. At the same time, they add some useful knowledge for comparison with other fire-prone Mediterranean ecosystems around the world.
Temporal fuel dynamics following high-severity fire in dry mixed conifer forests of the eastern Cascades, Oregon, USA
Authors: Dunn Christopher J. , Bailey John D.
Published: March 2015

Fire-resilient landscapes require the recurrent use of fire, but successful use of fire in previously burned areas must account for temporal fuel dynamics. We analysed factors influencing temporal fuel dynamics across a 24-year spatial chronosequence of unmanipulated dry mixed conifer forests following high-severity fire. Duff and litter accumulated as bark sloughed from snags and leaves senesced from recovering vegetation, averaging 14.6 Mg ha–1 and 22.1 Mg ha–1 at our 24-year post-fire site, respectively. 1-h fuels increased linearly, averaging 1.1 Mg ha–1 at our 24-year post-fire site, with additions occurring from recovering vegetation. 10-h and 100-h fuels exhibited non-linear temporal trends, with maximum loadings occurring 14 years (3.9 Mg ha–1) and 18 years (10.5 Mg ha–1) post-fire, respectively. 1000-h fuel accumulation slowed after 20 years post-fire (reached 124.6 Mg ha–1), concurrently with ~90% snag fall and fragmentation. Maximum herbaceous fuel loading averaged 0.73 Mg ha–1 at our 5-year post-fire sites, but only averaged 0.02 Mg ha–1 at all sites thereafter. Live shrub biomass accumulation slowed after 21 years post-fire, averaging 14.3 Mg ha–1 at our 24-year post-fire site. Managers can use post-fire temporal fuel dynamics to help facilitate the restoration of fire regimes while mitigating undesirable fire effects.
Relations between soil hydraulic properties and burn severity
Authors: Moody John A. , Ebel Brian A. , Nyman Petter , Martin Deborah A. , Stoof Cathelijne , McKinley Randy
Published: March 2015

Wildfire can affect soil hydraulic properties, often resulting in reduced infiltration. The magnitude of change in infiltration varies depending on the burn severity. Quantitative approaches to link burn severity with changes in infiltration are lacking. This study uses controlled laboratory measurements to determine relations between a remotely sensed burn severity metric (dNBR, change in normalised burn ratio) and soil hydraulic properties (SHPs). SHPs were measured on soil cores collected from an area burned by the 2013 Black Forest fire in Colorado, USA. Six sites with the same soil type were selected across a range of burn severities, and 10 random soil cores were collected from each site within a 30-m diameter circle. Cumulative infiltration measurements were made in the laboratory using a tension infiltrometer to determine field-saturated hydraulic conductivity, Kfs, and sorptivity, S. These measurements were correlated with dNBR for values ranging from 124 (low severity) to 886 (high severity). SHPs were related to dNBR by inverse functions for specific conditions of water repellency (at the time of sampling) and soil texture. Both functions had a threshold value for dNBR between 124 and 420, where Kfs and S were unchanged and equal to values for soil unaffected by fire. For dNBRs >~420, the Kfs was an exponentially decreasing function of dNBR and S was a linearly decreasing function of dNBR. These initial quantitative empirical relations provide a first step to link SHPs to burn severity, and can be used in quantitative infiltration models to predict post-wildfire infiltration and resulting runoff.

Published: March 2015

Significance

The application of luminescence imaging has been limited mainly by the two drawbacks of luciferases: low brightness and poor color variants. Here, we report the development of cyan and orange luminescent proteins approximately 20 times brighter than the wild-type
Renilla
luciferase. The color change and enhancement of brightness were both achieved by exploring bioluminescence resonance energy transfer (BRET) from enhanced
Renilla
luciferase to a fluorescent protein, a technology that we previously reported for the development of the bright yellowish-green luminescent protein Nano-lantern. These cyan and orange Nano-lanterns along with the original yellow Nano-lantern enable monitoring of multiple cellular events, including dynamics of subcellular structures, gene expressions, and functional status, such as intracellular Ca

Published: March 2015

Significance

Batteries run just about everything portable in our lives such as smartphones, tablets, computers, etc. Although we have become accustomed to the rapid improvement of portable electronics, the slow development of batteries is holding back technological progress. Thus, it is imperative to develop new energy storage devices that are compact, reliable, and energy dense, charge quickly, and possess both long cycle life and calendar life. Here, we developed hybrid supercapacitors that can store as much charge as a lead acid battery, yet they can be recharged in seconds compared with hours for conventional batteries.
Data commentary in science writing
Authors: Nordrum Lene , Eriksson Andreas
Published: March 2015

Data commentary, the verbal comment on visual material, is a complex area in
science writing; yet, few studies in academic writing focus on it. This chapter
presents an approach to the teaching and learning of data commentary in ESP
writing within the science disciplines involving direct application of a small,
specialized corpus of data commentaries drawn from published research articles
and master’s theses, all annotated for rhetorical moves. We exemplify how formative
self-assessment practices of data commentaries can be developed from
corpus-informed computer-assisted learning activities combining top-down
discourse analysis with bottom-up corpus analysis, and outline a methodology
for self-assessment practices. Our approach illustrates how a specialized corpus
and purposefully crafted learning activities can assist students in continuous
self-assessment practices. Such facilitation is of crucial value today as pedagogical
and curricular developments in science education increasingly emphasize
students’ awareness of communicative practices.
The contribution of management to economic growth: a review
Authors: Glaister Keith W.
Published: March 2015

A review of the literature indicates that the contribution of management to economic growth has been largely obscured in theory and ignored in empirical work. In contrast, the place of the entrepreneur in the process of growth is well recognised and widely accepted. The main goal of this paper is to develop an argument for the place of management in the process of growth, and to maintain that in the modern free market economy management’s role is at least as important as that of the entrepreneur. Routine innovation in established firms is emphasised as a fundamental, normal part of management activity, and as such highlights the importance of management for economic growth. However, management is not homogeneous and the actions of managers differentially affect the performance outcomes of firms. Hence the quality of management, and the adoption of appropriate management practices, matters and directly impacts economic growth. In recognising that management makes a significant contribution, both in terms of ensuring efficiency in the use of factor inputs and effectiveness in terms of driving incremental innovation, new research is necessary at the firm level in order to develop this understanding.
Buying monastic products, gift or purchase?
Authors: Paquier Marie-Catherine
Published: March 2015

Focusing on the act of purchasing retail monastic products, this article applies a cause-related marketing (CRM) approach within a Management, Spirituality, and Religion (MSR) framework. When they purchase monastic products, are individuals simply buyers or do they, by means of their actions, support a religious cause by combining a gesture of purchasing with a gesture of gift-giving? We conducted qualitative interviews with individuals making purchases at religious and secular points of sale in France, and subjected the data acquired to textual analysis. Four classes of meaning emerged. It transpires that gift and purchase are intertwined and systematically associated with a hedonistic sentiment combining pleasure, trust, and love. The soft expression of religiosity illustrates the phenomenon of spirituality taking refuge in the private sphere. Our results enrich the interdisciplinarity of MSR research, confirm the findings outlined in CRM literature, and provide monasteries with a better understanding of their customers.

It also considers versions by other denominations such as Jehovah's Witnesses with their own New World Translation of the Holy Scriptures, along with the New International Version and Today's New International Version by evangelical groups; the King James Only Movement, whose members prefer the KJV for literary or religious reasons; the readership of the KJV; and the KJV's influence on the development of the English language. The chapter concludes by assessing the status of the KJV in 2011.
Organizational Capability in the Public Sector: A Configurational Approach
Authors: Andrews Rhys , Beynon Malcolm J. , McDermott Aoife M.
Published: March 2015

This article brings together resource-based theory and contingency theory to analyze organizational capability in the public sector. Fuzzy-set qualitative comparative analysis is used to identify configurations of organizational attributes (department size, structural complexity, agencification, personnel instability, use of temporary employees), associated with high and low organizational capability in UK central government departments. Findings identify a single core configuration of organizational attributes associated with high capability departments—low structural complexity and personnel stability. Two core configurations are associated with low capability departments—personnel instability and the combination of structural complexity and departmental agencification. Based on the configurations evident in successful and struggling organizations, discussion illuminates potential organizational design strategies to improve public sector organizational capability.
Social Work Regulation
Authors: Knox Karen S. , Marks Andrew
Published: March 2015

Social work regulation refers to the laws, rules, and regulations that uphold the profession’s ethical and practice standards and mandate credentialing of social work professionals. Social work regulation specifies the required qualifications for social worker credentialing and the scope of practice and services that can legally be provided. Social work regulation in the United States is relatively new as concerted efforts were initiated in 1969, when the National Association of Social Workers (NASW) passed a resolution to pursue licensing in each state. By 1993, all of the states and the District of Columbia had implemented some form of regulation. Internationally, many European countries, Canada, the United Kingdom, and New Zealand mandate some form of social work regulation, but development is still in process for many countries. Social work regulatory processes are mandated through governmental boards and statutes from the jurisdiction’s legislative body. Another type of social worker credentialing is through voluntary membership in professional associations that establish practice standards and codes of ethics. Protection of the public is the primary focus for both types of credentialing. Governmental regulation protects recipients of social work services through an enforcement process and sanctions for unprofessional behavior with regard to social work values, ethics, and standards of practice. Typical sanctions may include revocation of the regulatory title, additional training and supervision, and treatment for impairments, such as mental illness or substance abuse. Voluntary membership organizations also have consequences for members who violate their standards or policies, usually withdrawal of credentials and dismissal from the organization. There are three types of regulation: licensing, certification, and registration. These titles are used interchangeably by regulatory authorities, and therefore, can be one and the same depending on the jurisdiction. Protection of the title of “social worker” is another purpose of regulation, to ensure that only professionals who satisfy the conditions of social work licensure can, by law or statute, call themselves social workers. These conditions usually require having a social work degree from a higher education accredited social work program and passing a licensing exam at the appropriate level of education and experience. The national licensing exams are administered in the United States and Canada under the authority of the Association of Social Work Boards (ASWB). Social worker regulation also requires continuing education or training to ensure professional competency, but jurisdictions vary greatly on their regulation requirements and titles, which can be confusing to both professionals and consumers.

Objective

Left ventricular (LV) hypertrophy in aortic stenosis (AS) constitutes a risk factor for cardiac morbidity and mortality. The aim of this study was to investigate the degree of LV mass regression after aortic valve replacement (AVR) with two alternative sutureless self-expanding strategies: Perceval S (Sorin Group, Saluggia, Italy) (P) and 3f Enable (Medtronic, ATS Medical, Minneapolis, MN USA) (e) aortic bioprostheses.

Methods

Between March 2010 and December 2011, 129 patients with symptomatic AS underwent AVR with the Perceval S or 3f Enable bioprostheses in two cardiac surgery departments (Massa, Italy; Nuremberg, Germany). We analyzed 45 patients in group P and 19 in group E undergoing isolated AVR with a 6-month follow-up. The LV mass was calculated using the Devereux formula and was indexed to body surface area.

Results

Baseline patient characteristics showed no significant differences between the two groups. There were no in-hospital deaths. Two patients in group P died at follow-up versus zero in group E ( P = 0.49). Mean LV mass index decreased from 146.6 (78) g/m2 at baseline to 123.3 (63) g/m2 at follow-up ( P < 0.001) in group P and from 146.1 (47.6) g/m2 to 118.1 (39.8) g/m2 ( P = 0.003) in group E, with no significant difference between the two groups ( P = 0.315). This effect was accompanied by significant clinical improvement. Conclusions: In isolated AS, AVR with sutureless bioprostheses is associated with a significant regression in LV mass at 6-month follow-up. No significant differences were present between the two alternative sutureless strategies. However, regression needs an evaluation with long-term echocardiographic examinations.
Procalcitonin as Biomarker of Infection: Implications for Evaluation and Treatment
Authors: Falcão Gonçalves Pedro , Menezes Falcão Luiz , Duque Pinheiro Isabel
Published: March 2015

Procalcitonin (PCT) is a quickly measurable marker, assumed to have high sensitivity and specificity for sepsis and infection. A literature search was conducted to evaluate PCT ability as a diagnostic and prognostic tool in infectious processes and its ability to monitor the antibiotic therapy. PCT level is increased in bacterial and fungal infections, but not in viral infections, with a significantly higher level in patients with bacteremia compared with uninfected patients (2.5 vs. 0.3 ng/mL; P < 0.0001). A PCT value of ≤0.1 ng/mL discards bacteremia and microbiological tests (negative predictive value of 96.3%), >0.1 ng/mL needs microbiological tests, and >1.0 ng/mL is indicative of bacteremia. Antibiotic treatment algorithms guided by PCT decreased the need for antibiotic treatment in approximately 50%. PCT is a promising test in clinical practice to decide the introduction of antibiotic therapy in addition to the existing tools, without neglecting the clinical assessment, with a significant decrease in costs.

Objectives:

Anastomotic ulcers are a known cause of anemia in children with a history of intestinal resection. Upper endoscopy and colonoscopy can be used to diagnose these ulcers; however, the area of involvement may be difficult to visualize with standard endoscopic techniques. Capsule endoscopy (CE) offers an alternative method for visualizing the small bowel in these patients. We describe a cohort of patients with short bowel syndrome (SBS) and anemia who had anastomotic ulcers detected by CE.

Methods:

Retrospective chart review of patients with SBS at our institution who underwent CE for chronic gastrointestinal (GI) blood loss.

Results:

Four patients who underwent a total of 6 CE procedures were identified. The underlying diagnoses included necrotizing enterocolitis (n = 2), gastroschisis (n = 1), and jejunal atresia (n = 1). All of the patients had their ileocecal valves resected during previous surgeries and had received blood transfusions within the previous several months. The median age at the time of CE was 5.5 years (range 4–14 years). Enterocolonic anastomotic ulcers were noted in the studies as wide, flat circumferential lesions with a white base. The CE results guided a change in medical management in all of the 4 patients, including surgical revision of their anastomosis.

Conclusions:

CE may be a helpful adjunctive tool for detecting anastomotic ulcers in patients with SBS and chronic GI blood loss.

Objective:

Prokinetic medications are used in premature infants to promote motility and decrease time to full enteral feeding. Erythromycin and metoclopramide are the most commonly used prokinetic medications in the neonatal intensive care unit (NICU), but their safety profile is not well defined.

Methods:

We conducted a large retrospective cohort study using data from 348 NICUs managed by the Pediatrix Medical Group. All of the infants exposed to ≥1 dose of erythromycin, metoclopramide, or both, from a cohort of 8,87,910 infants discharged between 1997 and 2012 were included. We collected laboratory and clinical information while infants were exposed to erythromycin or metoclopramide and described the frequency of laboratory abnormalities and clinical adverse events (AEs).

Results:

Metoclopramide use increased from 1997 to 2005 and decreased from 2005 to 2012, whereas erythromycin use remained stable. Erythromycin use was most often associated with a diagnosis of feeding problem (40%), whereas metoclopramide was most often associated with a diagnosis of gastroesophageal reflux (59%). The most common laboratory AE during exposure to erythromycin or metoclopramide was hyperkalemia (8.6/1000 infant days on erythromycin and 11.0/1000 infant days on metoclopramide). Incidence of pyloric stenosis was greater with erythromycin than with metoclopramide (10/1095, 0.9% vs 76/19,001, 0.4%; P = 0.01), but odds were not significantly increased after adjusting for covariates (odds ratio 0.52, 95% confidence interval [CI] 0.26–1.02, P = 0.06). More infants experienced an AE while treated with metoclopramide than with erythromycin (odds ratio 1.21, 95% CI 1.03–1.43).

Conclusions:

Metoclopramide was associated with increased risk of AEs compared with erythromycin. Studies are needed to confirm safety and effectiveness of both the drugs in infants.

Moments of zeta and correlations of divisor-sums: I
Authors: Conrey Brian , Keating Jonathan P.
Published: March 2015

We examine the calculation of the second and fourth moments and shifted moments of the Riemann zeta-function on the critical line using long Dirichlet polynomials and divisor correlations. Previously, this approach has proved unsuccessful in computing moments beyond the eighth, even heuristically. A careful analysis of the second and fourth moments illustrates the nature of the problem and enables us to identify the terms that are missed in the standard application of these methods.
Number fields and function fields: coalescences, contrasts and emerging applications

The similarity between the density of the primes and the density of irreducible polynomials defined over a finite field of
q
elements was first observed by Gauss. Since then, many other analogies have been uncovered between arithmetic in number fields and in function fields defined over a finite field. Although an active area of interaction for the past half century at least, the language and techniques used in analytic number theory and in the function field setting are quite different, and this has frustrated interchanges between the two areas. This situation is currently changing, and there has been substantial progress on a number of problems stimulated by bringing together ideas from each field. We here introduce the papers published in this Theo Murphy meeting issue, where some of the recent developments are explained.

Published: March 2015

MicroRNA (miRNA) sponges have been shown to function as competing endogenous RNAs (ceRNAs) to regulate the expression of other miRNA targets in the network by sequestering available miRNAs. As the first systematic investigation of the genome-wide genetic effect on ceRNA regulation, we applied multivariate response regression and identified widespread genetic variations that are associated with ceRNA competition using 462 Geuvadis RNA-seq data in multiple human populations. We showed that SNPs in gene 3’UTRs at the miRNA seed binding regions can simultaneously regulate gene expression changes in bothcisandtransby the ceRNA mechanism. We termed these loci as endogenous miRNA sponge expression quantitative trait loci or “emsQTLs”, and found that a large number of them were unexplored in conventional eQTL mapping. We identified many emsQTLs are undergoing recent positive selection in different human populations. Using GWAS results, we found that emsQTLs are significantly enriched in traits/diseases associated loci. Functional prediction and prioritization extend our understanding on causality of emsQTL allele in disease pathways. We illustrated that emsQTL can synchronously regulate the expression of tumor suppressor and oncogene through ceRNA competition in angiogenesis. Together these results provide a distinct catalog and characterization of functional noncoding regulatory variants that control ceRNA crosstalk.

Published: March 2015

Multireflection grazing-incidence X-ray diffraction (MGIXD) was used to determine the stress- and strain-free lattice parameter in the surface layer of mechanically treated (polished and ground) tungsten and austenitic steel. It was shown that reliable diffraction stress analysis is possible only when an appropriate grain interaction model is applied to an anisotropic sample. Therefore, verification of the X-ray stress factors (XSFs) was accomplished by measuring relative lattice strains during anin situtensile test. The results obtained using the MGIXD and standard methods (χ and ω geometries) show that the Reuss and free-surface grain interaction models agree with the experimental data. Moreover, a new interpretation of the MGIXD results was proposed and applied for the first time to measure the probability of stacking faults as a function of penetration depth for a polished and ground austenitic sample. The XSF models verified in the tensile test were used in the analysis of residual stress components.
Powder diffraction in Bragg–Brentano geometry with straight linear detectors
Authors: Kriegner Dominik , Matěj Zdeněk , Kužel Radomír , Holý Václav
Published: March 2015

A common way of speeding up powder diffraction measurements is the use of one- or two-dimensional detectors. This usually goes hand in hand with worse resolution and asymmetric peak profiles. In this work the influence of a straight linear detector on the resolution function in the Bragg–Brentano focusing geometry is discussed. Because of the straight nature of most modern detectors geometrical defocusing occurs, which heavily influences the line shape of diffraction lines at low angles. An easy approach to limit the resolution-degrading effects is presented. The presented algorithm selects an adaptive range of channels of the linear detector at low angles, resulting in increased resolution. At higher angles the whole linear detector is used and the data collection remains fast. Using this algorithm a well behaved resolution function is obtained in the full angular range, whereas using the full linear detector the resolution function varies within one pattern, which hinders line-shape and Rietveld analysis.
