A scheme for the calculation of NMR chemical shifts using local second-order Moller–Plesset (LMP2) perturbation
 theory together with gauge-including atomic orbitals (GIAOs) is presented. Test calculations on the
 basis of a preliminary implementation within a conventional GIAO-MP2 code show that the deviations between GIAO-LMP2 and GIAO-MP2 are small, e.g., for 13C typically less than 1 ppm, and that the GIAO-LMP2 approach holds
 great promise for application to larger molecules.


Denbufylline (1,3‐di‐n‐butyl‐7‐[2‐oxopropyl]‐xanthine) has been examined in passive avoidance trials in gerbils, following transient forebrain ischaemia, and in mice. Animals were conditioned to avoid a darkened compartment by means of a foot shock received upon entering. Learning and memory were tested 24 hr later by replacing the animals in the box and measuring the latency to enter the dark compartment. In gerbils, transient (5 min) forebrain ischaemia was induced 24 hr prior to training by bilateral closure of the carotid arteries. Controls were sham‐ligated. All gerbils received seven subcutaneous injections of saline or denbufylline, the first during forebrain ischaemia or immediately following sham‐ligation, and the rest 3, 6, 24, 27, 30, and 48 hr later. Mice received one subcutaneous injection of saline or denbufylline immeediately after training. The results show that denbufylline enhances memory formation in mice after a mild learning stimulus and recollection in gerbils following forebrain ischaemia.


H2S increases the thermal isomerization of butene-2 cis (Bc) to butene-1 (B1) and butene-2 trans (Bt) around 500°C. This effect is interpreted on the basis of a free radical mechanism in which buten-2-yl and thiyl free radicals are the main chain carriers. B1 formation is essentially explainedby the metathetical steps:

whereas the free radical part of Bt formation results from the addition–elimination processes:

. It is shown that the initiation step of pure Bc thermal reaction is essentially unimolecular:

and that a new initiation step occurs in the presence of H2S:

. The rate constant ratio has been evaluated:

and the best values of k1 and k1', consistent with this work and with thermochemical data, are

. From thermochemical data of the literature and an "intrinsic value" of E−3 ⋍ 2 kcal/mol given by Benson, further values of rate constants may be proposed:

is shown to be E4 ⋍ 3.5 ± 2 kcal/mol, of the same order as the activation energy of the corresponding metathetical step.


The utility model discloses a tubular pile reinforcing device. The tubular pile reinforcing device comprises cladding plates and a fixing part. The cladding plates are at least two in number, the cross sections of the cladding plates are arc-shaped, and connecting portions are arranged at two ends of each cladding plate. The fixing part is connected with two connecting portions arranged on the different cladding plates so that the cladding plates can be connected in a head-to-tail mode. According to the tubular pile reinforcing device, damage of tubular piles can be reduced, and damage caused by the tubular piles can be reduced.


Time-resolved measurements of the microwave field effect using optically detected EPR (ODEPR) have demonstrated that the amplitude and lifetime of the slow component of fluorescence are additionally reduced by an external microwave field, at a microwave frequency of 9400 MHz, a constant magnetic field of 0.3295 T and an oxalylfluoride pressure of 30 mTorr. This is accompanied by an increase in the fast component amplitude, at a constant decay rate of (2.36 × 0.19) 107 s−1. The fluorescence intensity was found to decrease, and phosphorescence intensity to increase, with subsequent saturation at higher microwave intensities. The experimental data are interpreted using the indirect mechanism theory in the limit of low-level density.


Background Immunotherapies have improved the treatment landscape for recurrent and metastatic head and neck cancers (HNC). Immune checkpoint inhibitors (ICI) have led to dura-ble benefit in approximately 20% of HNSCC patients. There-fore, predictive biomarkers are needed to identify those likely to respond or develop resistance to ICI therapy. retrospective study profiled pre-treatment for-malin-fixed paraffin-embedded (FFPE) tissues from metastatic HNC patients treated with immunotherapy at the Brisbane ' Here, image analytics tool Discovery ® ) to demarcate gross structures from H&E images (tumour, stroma, tertiary lymphoid structures, muscle, and vasculature) and per-region cell counts, informed our high-plex profiling of the tumour microenvironment using the Nanostring GeoMx Digital Spatial Pro-filer. Tumour and stromal were measured for 80-proteins simultaneously spanning immune cell typing, immuno-oncology drug targets, immune activation, pan-tumour, cell death, and PI3K/AKT panels. Each GeoMx ROI (H&E and 4-plex IF (DNA, PanCK, CD8 and CD3) was ana-lysed for percent tissue type (tumour, stroma, etc), per-subre-gion cell counts, simple cellular phenotypes, and spatial metrics between cell types. The protein findings were measured against response to ICI therapy (RECIST criteria) and overall survival parameters to identify tissue signatures associated with patient outcomes. High-plex validation of markers was performed using orthogonal multiplex tools. Results Our data revealed robust structural segmentation strat-egies to annotate tissues using H&E, which may sit upstream of high-plex spatial proteomic assays to identify regions of interest for selection and profiling. The study identified VISTA, CD66b, CD44 which were upregulated, and PD-L1, PD-L2, IDO-1 were downregulated in the progressive disease (PD) vs partial response (PR) comparison, respectively. Within the tumour microenvironment compartment, BAD, BIM and Phospho-PRAS40 were upregulated in the PD group, whereas Cleaved Caspase 9, HLA-DR and CD68 was upregulated in the PR group. A multi-marker signature composed of Pan-CK, PD-1, PD-L2 and cleaved caspase 9, co-localised in the tumour compartment was associated with a worse overall survival. development tissue-based signatures predictive of response/resistance to ICI


Mining of mineral resources results in extensive soil damage.Land use pattern is one of the main reasons for the process to restore the ecological integrity of these disturbed mine land areas.The research aim was to understand the influence of agricultural land use patterns on soil soil physical and chemical properties,soil nutrient,soil aggregate structure and soil enzyme activity.5 typical land use patterns of Pingshuo Surface Coal Mine have been chosen to study the effect of different land use patterns on soil reclamation of mining spoils.The results suggested that physical,chemical and biological disturbances of mining spoils lead to degraded soils quality.Protected agriculture,land use improved soil quality including soil nutrient,soil aggregate structure and soil enzyme activity.Cultivated area and artificial pasture land use patterns enhanced soil aggregate structure and soil enzyme activity,but not soil nutrient after 2 years of reclamation.


The present article highlights two impressive exhibition projects held at the Tsaritsyno Museum Preservation in 2017: A Garden Performance. The Art of Landscape Park in Europe and Russia (18.04–16.07.2017) and The Grooth Brothers: A Portraitist and an Animal Painter. The German Artists at the Russian Court (01.06–17.09.2017). Both themes — the history of landscaping and the creative activities of the travelling artists, migrating between different European countries — has long been the object of worldwide academic research. However, for the first time in Russia they have inspired such large-scale exhibition projects, addressing a wide range of issues. A Garden Performance… recreates the overall picture of the origin and further evolution of the landscape style during the 18th — first half of the 19th century, its history, classification, the artistic language of the garden itself and how it was reflected in literature, art and everyday culture. The Grooth Brothers… is a monographyof the work of German artists who settled at the Russian Court in the middle of the 18th century and made a significant contribution to the development of Russian art of that period. This particular project complements the exhibition Georg Christoph Grooth and the Elizabethan time, recently held at the Russian Museum (2.12.2016–13.03.2017). Both of the Tsaritsyno exhibitions show the results of passionate long-term research of their curators B. M. Sokolov and L. A. Markina. They are organized at a highly professional level, using technical resources of the modern day exhibition practice, with the support of many Russian museums, libraries, archivesand private collectors. Some exhibits were rarely accessible to the Moscow public before, others are presented inthese exhibitions for the first time. The latter are accompanied by published academic catalogues as well as by special programmes of events intended for professionals and the general public alike. Both exhibition projects are of great cultural and academic significance. Undoubtedly, they take our understanding of the aforementioned subjects to a new level.


"Why, sir," the student asks, "does Achilles drag the body of Hector around the walls of Troy?" "That sounds like a stimulating question. Most interesting. I'll bite," says the professor. "Well, you see, sir, the 'Iliad' is full of circles—shields, chariot wheels and other round figures. And you know what Plato said about circles. The Greeks were all made for geometry." "Bless your crew-cut head," says the professor, "for such a beautiful thought. You have exquisite sensibility. Your approach is both deep and serious. Still I always believed that Achilles did it because he was so angry."


As the number of space debris has increased rapidly in recent years, it poses a major threat to the safety of spacecraft in space, and damage assessment for space debris hypervelocity impact is very important. In order to more comprehensively and accurately describe the damage defects in the infrared inspection data collected by infrared thermal imaging technology, this paper proposes an ultra-high-speed impact damage detection algorithm based on infrared reconstruction image fusion. The algorithm first preprocesses the obtained infrared thermal response image sequence and separates the damage features, and then applies a multi-objective evolutionary optimization algorithm to extract the typical transient thermal response, and then reconstructs the feature infrared images. Finally, image fusion based on guided filtering is performed on the damage reconstruction infrared images. In this paper, several reconstruction images that represent different types of impact damage defect are merged together to improve the detection ability of the algorithm. Infrared detection experiments on damaged specimens obtained from actual hypervelocity impacts verify the effectiveness of the proposed algorithm.


ABSTRACT Parallel processing techniques have become widespreadin applications requiring very high throughput or which havereal-time deadlines. However, the potential gains from paral-lel processing can be diminished by the communication over-head inherent in these systems. With tightly-coupled architec-tures being used as the platform, an optimal way of schedul-ing the messages in a network is addressed. Static scheduling,while being able to utilize a priori information, is found tobe lacking when this information is unavailable or inaccurate.Dynamic scheduling can adjust to changes within the networkat run-time but suffers from not having any knowledge of thenetwork traffic environment. To solve this problem, we in-troduce a hybrid scheduling technique which seeks to extractthe best from each of these approaches. This hybrid schedul-ing technique incorporates a priority scheme derived from us-ing the newly developed Collision Graph model. The deter-mination of an optimal schedule is an NP-complete problem.Therefore, heuristics are used in the development of a prior-ity mapping algorithm to deal with a general case model ofmessage traffic. Experiments performed show a significantimprovement over baseline approaches.


The purpose of this study was to evaluate the factor structure and measurement invariance across gender and age of the Brief Resilience Scale (BRS) in 2272 Greek adults of the general population. The sample was split into three parts (20%, 40%, 40%). EFA was carried out in the first subsample (20%) evaluating 3 models. CFA was next carried out in the second subsample (40%) evaluating seven models. All models were examined further in a different CFA with a subsample of equal power (40%). The single factor of BRS was deemed unstable across the two CFA subsamples. A two-factor model was the optimal model emerged in the Greek context. Measurement invariance across gender and age was successfully established. Internal consistency reliability (α and ω) and AVE based convergent validity were adequate for the entire BRS. A consistent pattern of relationships emerged from correlation analysis with 12 different measures, suggesting convergent and discriminant validity. The distinctiveness of BRS from depression and stress was evidenced using CFA and EFA with different compound models of BRS and scales of depression, anxiety, and stress. These findings further confirmed that the Greek version of BRS has construct validity.

Finding solutions to the many water resource utilisation problems that face South Africa has been the driving force behind a large part of the hydrological research that has been undertaken in the country. Any review of the methodology and past or present issues of hydrology in South Africa would find it difficult to distinguish between those that are part of engineering hydrology, and those that are part of geographical hydrology. Both have a great deal to contribute to solving the water resource management problems of South Africa and these contributions should be made in a co-operative framework. As will be demonstrated in the paper, the changing face of South Africa and the requirements of managing water in a transformed, democratic society have made the need for co-operation across various disciplines even more essential.


1. Introduction. A 3D model of an Industrial Plant typically has representations of pre-defined engineering parts. These elements are described by an ISO standard (STEP-10303-227 [STEP01]) in the domain of Plant Design. The Application protocol 227 describes the specifics for plant spatial configuration. We integrated a module to explicitly associate this semantics to the geometric parts from a CAD reconstruction. Our design review walkthrough system for Plant Design uses semantic compression added to simplification techniques of the geometrical data to increase the efficiency and complement the traditional Computer Graphics methods in the field. The architecture of our system can be seen in figure 1.


We present the method for designing long-distance optical transmission systems with midway optical phase conjugation. The main cause of the waveform distortion in this type of system is found to be the sideband instability that is induced by the periodic signal power variation along the fiber link. It is shown that the effective waveform distortion compensation can be achieved by properly designing the amplifier spacing and the fiber dispersion to minimize the effect of the sideband instability.<<ETX>>

Specifically, the invention is a method for producing a coenzyme characterized by synthesizing NAD + or NADH in an enzyme reaction system that requires NAD + or NADH by adding one or more heat-resistant enzymes necessary for the reaction to synthesize NAD + from nicotinamide in the enzyme reaction, and a transformant set for coenzyme production characterized by comprising one or more transformants having a heat-resistant microorganism as the host, obtained by introducing a gene that encodes one or more heat-resistant enzymes necessary for the reaction to synthesize NAD + or NADH from nicotinamide.


The potential for contamination of surface and ground water by atrazine, applied preand postplant in a Eucalyptus nitens (Deane & Maid.) Maid plantation is investigated as part of a wider based Australian study. These studies aim to provide forest plantation managers with a better understanding of the processes involved in the behaviour of atrazine in the Australian environment. This information will in turn be used to develop management systems for the continued, safe use of atrazine in forestry. Atrazine was applied, by tractor, at 8 kg a.i. ha immediately prior to planting of E. nitens and again 12 months after planting in a 60 hectare catchment on the North West Coast of Tasmania. After spraying at regular fortnightly intervals, spot water samples were taken over periods of nine and 12 months respectively, whilst more intense water sampling occurred in association with rainfall events. Initially samples were analysed for atrazine, total suspended solids and turbidity. After the post-plant spray, water samples were analysed for atrazine and the metabolites desethylatrazine and desisopropylatrazine. Water sample results and relationships between water flow, metabolites and the parent compound will be discussed. The potential for the vertical movement of atrazine through a soil profile was determined by applying atrazine at 8 kg a.i. ha to a small area at the top of the catchment. Soil cores were taken at 1, 7, 14, 28, 56, 112, 280, 410 and 890 days after atrazine application. Atrazine half-life, and the potential for movement through the soil profile, will be discussed.


Phonon dispersion curves for Si and Ge are calculated by using the perturbation theory developed in our previous paper, where the perturbation theory based on pseudopotentials has been extended by taking into account higher order terms corresponding to the covalent bond effect so as to be applicable to IV and III-V covalent semiconductors. The resulting phonon dispersion curves are qualitatively in good agreement with experiment in spite of introducing no adjustable parameter and explain the crossing of LO and TO curves along the [100] direction and the minimum in [110] II optic mode near the zone boundary.

Connective tissue activating peptides from lymphocytes (CTAP-I) and platelets (CTAP-111) are known to stimulate glycosaminoglycan synthesis, glycolysis, and mitogenesis in connective tissue cell cultures. Direct evidence suggested that increased accumulation of cyclic AMP was involved in the action of these peptide agonists, and increased prostaglandin E synthesis was postulated on the basis of indirect evidence. In the present experiments, CTAP-I and -111 were incubated with human and murine cells in culture, and prostaglandin E was measured by radioimmunoassay using antibody directed primarily to prostaglandin E2. Both CTAP-I and -111 markedly stimulated the elaboration of prostaglandin E into culture medium, the earliest evidence of increased synthesis occurring at 4 hours with maximal concentrations found at 24 hours. Substantial residual stimulation persisted at least through 48 hours. Indomethacin (13.0 pg/ml) obliterated basal and incremental synthesis of prostaglandin in the presence of mediators.

Aims and Objectives: To study the profile of blood stream infections with Candida species, their current epidemiological trend at our setting, clinical management, resistance trends and outcome in terms of mortality. Methods: This is a prospective observational study conducted among all adult in-patients, at AIMS, Kochi from August 1st 2014 to February 28th 2016, both in wards and ICUs, who have positive isolates of Candida species in bloodstream infection among the positive blood culture samples. Incidence rate of Candidemia was calculated and distribution of Candidemia with respect to characteristics like age, gender, comorbid illness, mechanical ventilation, prior antibiotic therapy, prolonged ICU stay. Results: Out of 1600 blood stream infection isolates, Candidemia was fourth most common blood stream isolate infection in our study with an incidence rate of 7.5%. Candida tropicalis was the predominant species in our study (30.8%). Mortality rate due to Candidemia was (61%). Urethral catheterization, Central venous access, neutropenia at presentation, prior antibiotic therapy, renal failure, Dialysis patients, prolonged ICU stay were some of the risk factors found to be statistically significant in assessing the mortality of patients in our study with a p value of <0.001. Conclusion: All patients with Candidemia should be treated with an antifungal agent at the earliest without any delay, as delay causes increase in mortality. All vascular catheters should be removed to help clear Candida from blood more quickly. Improved survival was found with the use of an Echinocandin and the removal of central venous catheters.


The flow field around a Sharp cone model configuration has been investigated by means of Schlieren facility in hypersonic shock tunnel. The time dependent evolution of flow around a cone of angle 11.38° with base radius of 150mm has been visualized for a flow Mach number M = 6.5. Experiments have been carried out with Helium as driver gas and air as test gas to visualize the hypersonic flow field. The flow establishment, steady state, and termination process of the hypersonic flow have been visualized for two different angles of attack, namely 0°&5°. Experimentally measured shock angle compares well with the theoretical and the computational study. The measured shock layer thickness compares well with the numerical simulation for both angles of attack.

PEBAX[poly(ether-block-amide)-ZIF-8(zeolitic imidazolate framework) composite membranes were prepared with different amounts of ZIF-8; 0, 1, 3, 7, 10, and 20 wt%. Gas permeation experiment were performed by varying the temperature of 25, 35, 40°C under condition 6 kgf/cm2. Gas permeability of C3H6, C3H8 and selectivity (C3H6/C3H8) were investigated by increasing the amount of ZIF-8 in the PEBAX. The gas permeability of C3H6 and C3H8 increased as ZIF-8 content increased among 0 to 7 wt% range and decreased among 7 to 20 wt% range. When the ZIF contents of PEBAX-ZIF composite membrane were 7 wt%, the selectivity (C3H6/C3H8) was taken between 3.6 and 3.8 value and also had the lowest activation energy.


summary Who gains from genetically modified (GM) crops in Europe? We review the global impact literature and assess the potential value of GM crops for Europe and how this value is shared among stakeholders. The literature suggests that, on average, two thirds of the global benefits are shared 'downstream', i.e., among domestic and foreign farmers and consumers, while only one third is extracted 'upstream', i.e., by gene developers and seed suppliers. Can this global rule of thumb be extrapolated to the EU? We review studies on GM maize, sugar beet and oilseed rape in Spain, Hungary, the Czech Republic and the EU-25. The potential annual value of GM technologies for single Member States ranges from €0.1 million to €42 million, distributed according to the same rule of thumb. With a global annual value of €668 million, herbicide tolerance in sugar beet cultivation is the EU's most promising 'first-generation' GM technology The new Member States could also substantially benefit from GM crops. While the Czech Republic embraced GM maize in recent years, Hungary imposed a "de facto" ban on GM crops. By denying farmers access to potentially cost-reducing technologies, banning GM crops could be counterproductive for the future competitiveness of EU agriculture.

Zr-2.5Nb Pressure tube was used in the distilled water under high temperature and pressure. However, the evaluation of DHCV for pressure tube was limited in the air until now. Therefore, it was necessary for DHCV both in the air and in the distilled water under high temperature and pressure to evaluate. In advance, new DHC equipment simulating the real operating condition in the distilled water under high temperature and pressure was developed and DHCV test was conducted by this equipment. The test was carried out under simulated condition using distilled water of 250℃, 86bar and this result was compared with that of DHCV in the air of 250℃. DHCV of the distilled water was ranged from 8.42×10?? to 9.92×10?? m/s and the average value was 9.01×10?? m/s. As compared with the air condition, it was found that the characteristics of DHCV was not affected by the distilled water of high temperature and pressure. In addition, DHC equipment for high temperature and pressure was satisfied with the reliable conditions such as sealing, temperature control and data acquisition.


This paper discusses the different features of ANSYS and LS-DYNA in solving structural analysis using finite element approach. ANSYS and LS-DYNA are two popular engineering software tools that are used for finite element analysis. The difference between ANSYS and LS-DYNA lies in different solution procedures and time integration methods they use. ANSYS is an implicit analysis program while LS-DYNA is an explicit analysis program. This paper compares the general properties of the two programs through an impact problem and explains the reason. A simple two degrees of freedom system is solved to show how the implicit and explicit methods are implemented. Conclusively, advantages and limitations of both programs are discussed as well as their applicable areas.


Gross primary productivity (GPP) is an essential parameter to assess the efficiency of terrestrial ecosystems on carbon transfer. Although GPP is regularly measured with eddy covariance (EC) systems, these are restricted to the tower footprint area, and remote sensing (RS) products have estimated GPP using multispectral vegetation indexes (VIs) from farms to whole ecosystems. Indeed, nowadays, unmanned aerial vehicle (UAV)-based RS technology is becoming more accessible. Accordingly, we propose the estimation of GPP using VIs at high spatial resolutions using UAVs and multi-spectral cameras. A small typical farm in Colombia was cultivated with carrot as our base crop. An EC system was installed to estimate GPP and was used as a reference. A total of 24 VIs from UAV-based RS products were selected and compared with the GPP of the EC system. A cross-validation process was performed, and seven VIs obtained a high R2 score (0.76–0.78). The accumulated GPP, estimated with the best index (NIRv) was 520.3 g C m−2, while the GPP-EC estimate was 580.4 g C m−2 (10.3% error). This work showed that it is possible to estimate the GPP of carrot crops using UAV-based RS, VIs, and linear regression models, which can be used in further research on GPP using UAVs.


three-dimensional numerical simulations, from observed channel geometries and extrap-ABSTRACT Multiple-gate FETs is normally constructed on pre-etched silicon fins. These devices often present casual width variations along the silicon height; mostly caused by technological limitations of the fin definition process, due to non-ideal anisotropic etch. The resulting devices have, consequently, non-rectangular cross-sections, which can affect their electrical behavior. This work addresses the dependence of fin width non-uniformity on the occurrence of short-channel effects through comparative analysis, based on three-dimensional numeric simulation of non-rectangular cross-section devices. The influence of the fin cross-section shape on electrical parameters showed to be dependent on channel length, becoming more sensible to the fin shape as the channel length is reduced, with better DC performance present on devices with bottom fin width smaller than top fin width due to the higher transconductance and lower output conductance, resulting on higher intrinsic voltage gain. For opposite fin shapes the total gate capacitance present higher values, beneficiating AC analog parameters, such as


With the development of UAV technology, pedestrian trajectory extraction based on UAV video plays an increasingly prominent role in public safety. Aiming at the problems of small pedestrian targets in UAV video and the effect of pedestrian detection and tracking is easily blocked by obstacles in the scene, this paper analyzes the multi-target tracking algorithm framework based on detection, takes YOLOv5 as the target detection model, and gets a better anchor frame through KMeans++ clustering method. At the same time, CBAM attention module is integrated into YOLOv5 network to realize the effective extraction of small target features; With Deep_SORT is a target tracking model. By calculating the confidence of the trajectory, an improved correlation matching tracking algorithm framework is proposed to solve the problems of trajectory fracture caused by pedestrians being blocked, and provide a strong guarantee for extracting complete and reliable pedestrian trajectory information in UAV video. The mAP of this paper is 49.1 % on the VisDrone2019-DET dataset, and the MOTA is 48.0% on the VisDrone2019-MOT dataset. Experiments show that the pedestrian trajectory extraction method in this paper can extract more stable and continuous pedestrian trajectory.


Recent advancements in drone technology and base station miniaturization, together with an urgent need to reduce site rental costs, have created the unique opportunity to deploy cellular networks on a platform of mobile drones. This new development is redefining the wireless networks, as drone base stations can autonomously move in space to improve coverage and capacity of the network, tremendously enhancing the quality of service (QoS) for conventional cell-edge users. In this research, we first address the possibility of deploying drone base stations and focus on the practical limitations of drones to be used in cellular networks. Then, after validating the performance of drone base stations analytically, we design autonomous mobility control algorithms for drones to improve the spectral efficiency of the floating base stations. As the optimal mobility control is NP-hard, we propose a range of practically realizable heuristics with varying complexity and performance. Simulations show that the proposed heuristics can readily achieve significant improvement in terms of spectral efficiency, packet throughput, and transmission time. A surprising outcome is that even moving the drones at minimal speeds can achieve these gains, making it possible to avoid any negative effect on drone battery lifetime.


Atom probe tomography (APT) is an extremely powerful technique for determining the three-dimensional structure and chemical composition of a given sample. Although it is designed to provide images of material structure with atomic scale resolution, reconstruction artifacts, well-known to be present in reconstructed images, reduce their accuracy. No existing simulation technique has been able to describe the origin of these artifacts. Here we develop a simulation technique which allows for atomistic simulations of the atom emission process in the presence of high electric fields in APT experiments. Our code combines hybrid concurrent electrodynamics—molecular dynamics and a Monte Carlo approach. We use this technique to demonstrate the atom-level origin of artifacts in APT image reconstructions on examples of inclusions and voids in investigated samples. The results show that even small variations in the surface topology give rise to distortions in the local electric field, limiting the accuracy of conventional APT reconstruction algorithms.


Using a torsion balance immersed in water and natural rubber ring specimens cured with di‐tertiary‐butyl‐peroxide, measurements were made of the isothermal volume dilation of rubber for mean extensions e=14, 33, and 51%, thus extending the results of Gee, Stern, and Treloar to lower strains. Chain molecular weights Mc=3000, 4400, 5100, and 5500 were employed. The chain molecular weights were determined by swelling in benzene, the uncertainty in each determination being about 10%. Observed fractional volume increases ranged from 3.2×10−5 for e=14% and Mc=5500 to 14×10−5 for e=51% and Mc=3000. Using Gee's expression for the volume dilation, but obtaining the slope of the stress‐strain curve from the statistical theory, curves were fitted to the data. The fitting process constituted a determination of Young's modulus E for each rubber specimen. The resulting curves are in good agreement with those of Gee, Stern, and Treloar. Additional determinations of E were made from rough stress‐strain curves and from th...


A topological insulator has a pair of extended states at the edge in the bulk insulating regime. We study a geometry in which such edge states will manifest themselves in a qualitative manner through periodic oscillations in the magnetoconductance of a singly connected sample coupled to leads through narrow point contacts. Detailed calculations identify the parameters for which these oscillations are expected to be the strongest, and also show their robustness to disorder. Such oscillations can be used as a spectroscopic tool of the edge states. A large change in the device resistance at small $B$, termed giant edge magnetoresistance, can have potential for application.


Using a recently discovered peptide ligase, butelase 1, we developed a novel method to access protein thioesters in good yield. We successfully combined it with native chemical ligation and sortase-mediated ligation in tandem for protein C-terminal labeling and dual-terminal labeling to exploit the orthogonality of these three ligation methods.


SUMMARY The intertidal vegetation of Hilbre Island, Merseyside, is compared with that of seven unpolluted localities on the Isle of Man and with that of New Brighton, Merseyside, which is grossly polluted. The Hilbre and New Brighton samples may be assigned either to the littoral fringe or to the eulittoral zone but not to the sublittoral fringe as defined by Lewis (1961). The Hilbre samples are floristically intermediate between those from New Brighton and the Isle of Man. This intermediate character is also apparent in species diversity, life-form composition, biomass and dominance. These features, together with historical evidence, illustrate the process of degradationl which the Hilbre vegetation has undergone throughout this century, and suggest possible future trends.


We study the gains from using short-dated options for volatility measurement and forecasting. Using option portfolios, we estimate nonparametrically spot volatility under weak assumptions for the underlying asset. This volatility estimator complements existing ones constructed from high-frequency returns. We show empirically, using the market index and Dow 30 stocks, that combining optimally return and option data can lead to nontrivial gains for volatility forecasting. These gains are due to "diversification" of the measurement error in the two volatility proxies. The information content of short-dated options, not spanned by the current spot volatility, is of limited relevance for volatility forecasting.


P178 An Efficient Least–Squares Migration R.J. Leggott* (CGGVeritas) R. Wombell (CGGVeritas) G. Conroy (CGGVeritas) T. Noss (CGGVeritas) & G. Williams (CGGVeritas) SUMMARY Seismic migration was originally devised for converting a recorded seismic dip into geological dip. These days migration is also expected to provide the correct amplitudes (reflectivity) as well as accurately positioned reflections. Modern migration algorithms usually achieve this with marine streamer data where there is good spatial sampling. For OBS and onshore seismic data however migrated images often exhibit "acquisition footprints" which prevent accurate analysis and interpretation. The operator required for migration algorithms to form an accurate image

The seismic response of Zhoutouzui Immersed Tunnel in Guangzhou was analyzed by using the elastic foundation beam approach.Special attention was paid to the axial force,the shearing force and the bending moment distributions along the immersed tunnel in longitudinal and lateral direction for the cases of the rigid connection,hinge connection and imperfect rigid connection between each tunnel segment.This paper presents some selected results,including: 1) the curves of the axial forces,the shearing forces and the bending moments in the immersed tunnel are similar to the curves of the seismic excitation;2) the maximum axial force,shearing force and bending moment in the immersed tunnel for the rigid joint case are larger than those for the hinge joint and imperfect rigid joint cases;3) the mechanics performance for the imperfect rigid connection case can be improved through the reduction of the axial forces,the shearing forces and the bending moments under earthquake excitation,which is consistent with the result from other literatures;4) the internal force and angular distortion of the joint are relatively large for the imperfect rigid connection;therefore.There is a need to calibrate the internal force and the relative displacement of the joint in engineering practice.


compatible avec l'hypothèse d'un rôle d'EphA7 dans le maintien ou la fonction de certaines synapses du SNC adulte. Abstract EphA7 is a member of the Eph receptor tyrosine kinase family. It plays multiple roles during central nervous system development. In adult brain, EphA7 is still strongly expressed in certain regions, notably regions known to undergo active synaptic plasticity, such as the hippocampus and cerebellum. To examine the regional and cellular localization of EphA7 in adult brain, we used in situ hybridization as well as immunohistochemistry for light and electron microscopy. By in situ hybridization, the strongest signal was in hippocampus, notably the main cell layers of CA1, CA3 and dentate gyrus, and in cerebellar cortical Purkinje cells. However, moderate mRNA levels were found in habenula, striatum, amygdala, cingular, piriform and entorhinal cortex and in the cerebellar cortex. After immunoperoxydase labeling, EphA7 appeared enriched in the neuropil layers of CA1, CA3 and DG as well as in Purkinje cell somata of the cerebellar cortex. In all examined layers of hippocampus and cerebellum, dendritic spines, dendrites, unmyelinated axons, axon terminals and some astrocytic leaflets were immunopositive for EphA7. Neuronal cell bodies of pyramidal, granular and Purkinje cells also showed some immunoreactivity, which was mainly intracellular. EphA7-labeled dendritic spines and dendrites represented the most frequently labeled components. The vast majority of labeled dendritic spines established asymmetric synapses with unlabeled axon terminals and thus displayed features of excitatory synapses. The dual preferential localization of EphA7 in dendrites and in the post-synaptic densities of dendritic spines provides morphologic v evidence in support of the hypothesis that EphA7 plays a key role in adult CNS synaptic maintenance or function.


Based on a longitudinal study of a Pupil Referral Unit (PRU) in England for children excluded from mainstream schools and utilising a moral economy lens, this article explores how solidarity is created and maintained in a very particular community of teachers and learning support assistants (LSAs). A moral economy approach highlights the centrality of people's moral norms and values for understanding the multi-layered dimensions of solidarity in organisations and how it changes in the context of transformations in the labour process. The article illustrates how teachers and LSAs rely on mutuality, underpinned by moral norms of justice, and values of care, dignity and recognition, to cope with physically and emotionally demanding work that is under-resourced and undervalued. The analysis reveals that solidarity is not only against unjust workplace regimes, but also for connectivity and a humanised labour process.


The current research used a grounded theory approach (Charmaz, 2006) to
explore the ways in which a small group of teachers working in mainstream
schools constructed the term 'mental health' and how they responded to young
people who may be experiencing 'mental health' problems. The findings
indicated that four conceptual categories emerged from the data. One of the
conceptual categories indicated that the teachers had two constructs of mental
health, with one construct suggesting teachers felt mental health language was
limiting for young people. Conversely, it was also found that mental health
language could have a motivating effect on the teachers in being able to know
how to respond to young people with mental health problems. In addition, it
was found that the teachers lacked confidence in sharing ownership of the term
'mental health'.
The research findings also highlighted two further conceptual categories with
regards to the teachers' responses to young people with mental health
problems. The teachers were active in engaging in a collective responsibility
with their teaching colleagues when responding to mental health problems. The
teachers also used their interpersonal and intrapersonal skills to develop
relationships with young people in the hope that this will help them to regulate
and contain their emotions.


The paper is concerned with applications of the standard Nevanlinna–Pick problem in various technical domains, namely the following: interpolation by reflectance functions, polynomial stability checking, cascade synthesis of passive one-ports, and model reduction with a Hankel norm criterion. Some fundamental results on the Nevanlinna–Pick problem are shown to be of a definite interest in each of these subjects.


Abstract: This chapter focuses on the enteric viruses, hepatitis A virus and norovirus, responsible for the main outbreaks linked to shellfish consumption. One major drawback for viral contamination estimation in shellfish is the lack of indicator or standardised method, preventing systematic control. After a review of the main sources of pollution, we identified the conditions responsible for shellfish contamination. This will help to set up potential strategies to reduce contamination in harvesting areas such as the limitation of faecal input or the improvement of tools for management. As knowledge is progressing risk management, strategies will help to protect the consumer and will also led to improve regulation. Rapid alert systems need to be set up to prevent coastal area contamination and promising examples of coastal management have proved their efficacy to reduce faecal load and thus, improve water quality. Shellfish have long been recognised as being beneficial to human health and this benefit should also be taken into consideration in managing coastal areas and preserving the water quality.


A new approach to the creation of microwave radiothermography is shown. Scientific and technical barriers preventing the creation of relatively inexpensive devices for early diagnosis of tumors, as well as painless and safe monitoring during treatment were identified. An optimal principle of construction of microwave radiothermography based on monolithic integrated circuits is offered.


Objective To observe dilation of Vichow-Robin Spaces(VRS) in the rat model of vasogenic brain edema,and investigate the mechanisms of the dilated VRS.Methods Twenty SD male rats were divided into two groups;model group and control group in = 10 each).In model group, all rats were injected intraperitoneally with phenylephrine hydrochloride(6.0 mg/kg,q8 h,for three times),while control group rats were injected with saline.After 48 h,all rats were executed under anesthesia with chloraldurat.The brain tissues were sliced into sections with a freezing microtome after perfusion fixation and observed under light microscope after HE staining.The features of VRS were observed and quantified by Mias 2000 image analysis system.Results There were many significant symptoms in model group after injection,such as urinary incontinence, shortness of breath,contraction of erector muscle,eyeball proptosis,limb twitch.Under the optical microscope,model group showed apparently dilated VRS,tissues around VRS were pale,crumbly and lightly stained,some even had sponge-like edema,while the control group was not the case.Compared with the control group,the numbers of dilated VRS in modol group were notably increased(P0.01).Conclusion As blood-brain barrier is damaged by sharply increased blood pressure,tissue fluid is collected in the VRS,therefore,the VRS expands and the brain swells.


This draft recommendation aims at defining the conditions of use of bolting in underground constructions (excluding mines) and facilitating the selection of bolting parameters. After recalling the historic development of the use of bolts and role of bolting, the author describes the different types of bolt: bolts anchored at one point only (mechanical Anchorage or Anchorage with resin), bolts sealed over their whole length (with injected grout or resin), or cast-in-situ. Mention is made of the influence of the geometry of the structure and of the methods of execution. A table proposes a simplified way of applying the conditions of use of bolting to the nature of the terrain. Attention is drawn to the fact that bolting, which is one of the rare means of support which is an in-depth treatment around a cavity, necessitates a wide experience and the control of the effectiveness of the support by means of non-destructive methods.

Abstract Aims: To elucidate the relationship between low circulating serum vitamin D levels and pre–disease conditions (ie, prediabetes and prehypertension) in healthy Mexican American adults. Methods: Analyses were conducted using data from the United States National Health and Nutrition Examination Survey (NHANES) from 2001 through 2006. Free–living (ie, community–dwelling, nonimprisoned) adult Mexican American subjects (N = 788; men, n = 443; women, n = 345) who had provided written informed consent and had no history of diabetes, hypertension, dyslipidemia, metabolic syndrome, and/or cardiovascular disease were included in this report. Participants were not ingesting any prescription medications, nor did they exhibit any evidence of malabsorption. Participants were determined to be disease free. Results: The mean serum vitamin D level for Mexican American adults (N = 788) of 50.5 nmol/L was significantly higher (P < 0.0001) than the mean of 35.9 nmol/L for non–Hispanic black adults (n = 621), and significantly lower (P < 0.0001) than the mean of 65.0 nmol/L for non–Hispanic white adults (n = 1711). Although age, sex, and body mass index were all significantly associated with prehypertension and prediabetes, no such association was found for serum vitamin D levels. Conclusion: A successive, incremental shift of approximately 15 nmol/L in vitamin D distribution was seen in the transition from the dark–skinned non–Hispanic black population to the brown–skinned Mexican American population, and from the brown–skinned Mexican American population to the non–Hispanic white population. In contrast to the non–Hispanic black and non–Hispanic white populations, wherein previous studies found that serum vitamin D levels below the 75th percentile were associated with prediabetes and prehypertension, no such association was detected among the Mexican American population. The reason for this lack of association among the Mexican American population is unclear.


When the optimum minimum coal charge crushing level is attained, an increase in the bulk density and a decrease in crushing costs are achieved. As applied to the conditions of the Novolipetsk Metallurgical Association in particular, a decrease in the extent of charge crushing of 1% facilitates an increase in the bulk density of 0.35-0.52%. The optimum minimum crushing level must be selected from the condition for obtaining coke which most fully meets blast-furnace production requirements. Industrial investigations were carried out at the Novolipetsk Metallurgical Association; an optimum coal charge crushing level (differential crushing scheme) for batteries No. 1-4 and 5-8 was selected on the basis of these investigations.


The morphology and the structure of the Al-Mn alloys electrodeposited from the molten A1Cl3-NaCl-KCl-MnCl2 salts were investigated using scanning electron microscope, X-ray diffraction.The alloys became lustrous with an increase in Mn content. X-ray diffraction patterns of these alloys showed that the alloys of lower Mn content consisted of α-Al crystalline phase. With an increase in Mn content, the intensities of the diffraction peaks from the crystalline phase decreased, while a broad peak appeared.Further, the microstructures of electrodeposited Al-Mn alloys of various Mn content were observed by transmission electron microscope. The electron diffraction pattern of ca. 7 mass % Mn alloy showed α-Al polycrystalline phase. With an increasing Mn content in deposit, the alloy phases changed from a-Al to amorphous phases. These phases showed lamellar structure which was parallel to the substrate.In electron diffraction images of Al-Mn alloy of ca. 30 mass % Mn, four broad rings were observed and they werereflected from microcrystalline intermetallic compound Al6Mn with the grain size of 3 to 5nm.

The so‐called "American" century is about to close. Despite the ethnocentric terminology, one cannot deny the power and influence the U.S. has wielded over the last 100 years. That hegemony has been achieved largely through military victories but also less overtly and perhaps more effectively through ideological conquest. Capitalism and American popular culture intrude pervasively around the globe, and Michael Jordan has become the earth's most recognizable figure. Since an alternative, oppositional ideology, communism, also existed for much of this century, how did capitalism prevail?


This work comprises a statistical grouping of data based on the clinical histories and findings in cases seen in private practice in the city of Caracas during the period from March 1917 to November 1932. A total of 12,000 patients with ophthalmologic conditions is listed, in 9,450 of whom the fundus was examined. (The reason for the exclusion of the remaining 2,550 from this part of the routine is not stated.) Of those examined, 1,225 showed lesions in one or both fundi; among these were 153 patients who exhibited more than one classifiable condition. The lesions are grouped in a purely descriptive or topographic manner. Regarding the general condition of the patients, the author has limited himself to a notation of the disease or diseases present at the time of observation of the pathologic changes in the fundus. Frequently no speculation is made as to the cause and effect, this


Context: Neuromuscular complications in the intensive care unit (ICU) are frequent, multifactorial, and clinically difficult to recognize during their acute phase. The physical examination is the starting point for identification. Case Report: We present a patient with a history of poorly controlled asthma who was admitted to the ICU with status asthmaticus. After 4 days of being under ventilatory support, he developed muscle weakness. The diagnostic approach made it possible to establish myopathic and neurological compromise through electrophysiology studies. Conclusions: ICU-acquired weakness (ICUAW) can bring long-term consequences, early identification, and management, as well as preventive measures, are essential to minimize chronic disability and morbidity.


Simple Summary Optic nerve sheath meningiomas (ONSM) are a rare subtype of meningioma. Only four retrospective studies with 3–21 patients have been published on the treatment of ONSM by radiosurgery. This study represents the largest published series on robotic radiosurgery to date, treating 25 patients with 27 ONSM lesions. Furthermore, hypofractionated radiosurgical treatment proves to be a safe alternative to surgery and fractionated stereotactic radiation with an overall local tumor control rate of 96.0% and stable or improved visual acuity in 90.0% and 10.0% of patients, respectively. We believe that our study makes a significant contribution to the literature, as our results indicate that robotic radiosurgery is a safe and effective treatment for the management of ONSM and offers a potential treatment option that would improve patient care and clinical outcomes. Abstract The role of robotic radiosurgery (RRS) in the treatment of optic nerve sheath meningiomas (ONSM) remains controversial and it is only performed in specialized institutions due to tight dose constraints. We evaluated the effectiveness and safety of RRS in the management of ONSM. Twenty-five patients with 27 ONSM lesions who underwent RRS using the Cyberknife (CK) system were retrospectively analyzed (median age, 47.9 years; 84.0% women). Multisession RRS was used with 4–5 fractions with a cumulative dose of 20.0–25.0 Gy in 84.0% of patients and a single fraction at a dose of 14.0–15.0 Gy in 16% of patients. Prior to RRS, seven (28%) patients experienced blindness on the lesion side. In those patients with preserved vision prior to radiosurgery, the visual acuity remained the same in 90.0% and improved in 10.0% of the patients. Overall local tumor control was 96.0% (mean follow-up period; 37.4 ± 27.2 months). Neither patient age, previous surgery, or the period from the initial diagnosis to RRS showed a dependency on visual acuity before or after radiosurgery. RRS is a safe and effective treatment for the management of ONSM. Hypofractionation of radiosurgery in patients with preserved vision before CK treatment results in stable or improved vision.

Peripheral neuropathy is a major adverse event associated with oxaliplatin-based chemotherapy and is a major dose-limiting adverse event in clinical practice. However, some patients treated with oxaliplatin may show no or minimal peripheral neuropathy. These differences are still poorly understood. The data on patients with colorectal cancer who received oxaliplatin-based regimens between January 2005 and June 2010 at South Miyagi Medical Center were retrospectively retrieved from the medical records. We selected 51 patients, and factor analysis was performed. The serum chlorine (Cl) level at baseline was significantly higher in patients with a high frequency of peripheral neuropathy (106; range 104 - 107 vs. 104; range 101 - 104 mEq/L, p = 0.02). Principal component analysis showed the variables Cl, body mass index, status of liver metastasis, and status of lymph node metastasis were related to the incidence of peripheral neuropathy. Discriminant analysis showed the model had predicted 72.5% of peripheral neuropathy. An understanding of the patient's characteristics could be useful for preventing or predicting oxaliplatin-induced peripheral neuropathy.


Internet banking has a very important place in the banking sector. The majority of banks located in Turkey offer many technological services. However, it is also seen that the use of internet banking does not reach the desired levels. The purpose of this study is to determine the factors affecting the internet banking preferences of the bank customers and the relationships between the demographic characteristics of bank customers and internet banking usage in Usak city of Turkey. Data from the questionnaires were analyzed using factor analysis, t-test and ANOVA analysis. As a result, seven factors were found to be effective in the use of internet banking. These are (1) "effect of social circle"; (2) "benefits of internet banking"; (3) "the usefulness of internet banking"; (4) "speed and time savings"; (5) "ease of use and cost"; (6) "the ability to use the internet and the advantages of internet banking"; and (7) "the suitability to life and work style." In addition, it was determined that there is a significant relationship between the demographic characteristics of bank customers and internet banking usage.

At a meeting of the Instituto di Correspondenza Archeologica held in 1852, a Jesuit archaeologist, R. P. Gianpietro Secchi, gave a brief account of an inscription which had recentlv come to light.' It was engraved on a thin plate of gold, and the circumstances of its discovery w'ere strange indeed. The excavator, Gaetano Canestrelli, found it in the mouth of a skull-noteworthv, according to the report. for its perfect set of strong teeth-which was enclosed in a terracotta urn unearthed at the Vigna Codini, near the tonmb of the Scipios; the neighboring ground had already yielded a numnber of leaden curse-tablets. The present location of the gold plate is unknowvn, at least to me; the scholars who have disctussed it since Secchi seem to have done so without re-examining the object. Secchi's reading of the inscription is as follows:


Purpose: The paper is an attempt to enter the discussion in the subject literature on elucidating problems in the non-systemic approach to managing the bank as an organization. The purpose of the paper is to identify the contradictions within which banks are managed, and which are aggravated in contingency situations. Due to the sensitive matter of the services they provide, banks are institutions that require special attention particularly now, when the COVID situation is radically testing management quality. Design/methodology/approach: The paper is the result of a literature review. Findings: The epistemological studies conducted have culminated in a framework of contradictory determinants shaping bank management during fast-paced changes in market conditions. The theoretical construct proposed may be a point of departure for empirical verification and further analytic work on the capacity of banks to reconcile the antinomies identified in the paper. Originality/value: The study makes it possible for managers to fill the knowledge gap with respect to areas and implications of the identified contradictions. Awareness of their existence and, as a result, management that supports processes for responding to a volatile environment is particularly useful in crisis situations. The proposed theoretical concept may be applied to identify antinomies or their lack in other areas of management research for various organization types.


Inversing the STICS crop model with remote-sensing-derived leaf area index (LAI) and yield data from the previous crop is used to retrieve some soil permanent properties and crop emergence parameters. Spatialized nitrogen (N) fertilization recommendations are provided to farmers, for the second and third N applications, following the screening of eleven N application rates under a range of possible forthcoming climates, with the objective to maximize of the gross margin while respecting some environmental constraints. As a first field validation, we show (1) the improvement brought by the assimilation of LAI and yield into STICS to simulate crop and soil variables and (2) the interest of site specific application to maximize both the gross margin and the agro-environmental criterion.

This paper investigates the influence of radius on the deformation of curved box girder bridges under the action of pre-stressed tendons. A spiral pre-stressed concrete box girder bridge in Chongqing is analyzed by using nonlinear finite element program ANSYS. The five different curved bridge models under weight and prestressing were created and the sameness and difference among them are gained and compared by numerical simulation. The results showed: 1. In five different situations, the box girder all occurs the vertical, radial and longitudinal deformation, among which vertical deformation is the main. At the same time, the box section occurred reverse and distortion, and the whole body of the beam rolls out. 2. The value of vertical displacement of mid-span of continuous curved box girder bridges relates with the horizontal radius. When the radius between one hundred meters and one hundred fifty meters, the influence of displacement is most sensitive, on the contrary, when the radius greater than two hundred meters, the influence of displacement is almost no effect to mid-span displacement.


In this paper, we analyze the influence of solders on the near-field shielding effectiveness. The solders in different height, shape and distribution have different influences on the system in package (SiP) radiation. Based on this study, we modify the simulation model of SiP and make the shielding effectiveness (SE) results from simulation and measurement agree with each other.


A new deployable mast for realization of large, deployable space structures such as antennas of high arperture, long instrument booms, large solar arrays or solar sails has been developed at the DLR. The triangular truss is based on the use of longerons of composite tapes and shows a signicant increase in mass eciency compared to existing deployable mast concepts. The longerons of thin carbon bre tapes enable realization of large cross-sectional dimensions which leads to a strong insensitivity of critical compression load towards element length. Thereby, in comparison to trusses with longerons of solid rods - the most commonly used type of longerons - higher truss bay length and radius can be achieved for a lower amount of structural mass. This directly contributes to bending stiness and strength. The folding mechanism makes use of the high deformation capability of longerons of tapes in attened state. It is based on a two path folding pattern where the truss is attened rst in cross-direction and reeled up afterwards. This is enabled by the combined use of exible longerons and hinges added to one batten row and ensures high volume eciency. This is especially true for very long masts as the stowage volume mainly depends on the intial reeling radius.


In this paper we present a novel nanoantenna (nantenna) design for energy harvesting. The nantenna has an "E" shape and is placed on a SiO2 substrate. Its operation is based on the excitation of surface plasmon polaritons through the gold arms of the E shape. By varying the lengths and widths of the arms, two overlapping working bandwidths can be achieved. This results in a wideband behavior characterized by a full width at half-maximum of about 2.2 μm centered around 3.6 μm. Two orthogonal E nantennas are placed perpendicular to each other to realize a dual-polarized nantenna. This nantenna can receive the two incident polarizations at two separate gap locations with very high isolation. The proposed structure can be used in several energy harvesting applications, such as scavenging the infrared heat from the Earth and other hot objects, in addition to optical communications.


An undergraduate course in Formal Languages and Automata Theory (FLAT) involves different topics that are core to the CS curricula and whose level of abstraction makes them difficult both to teach and to learn. Such difficulty stems from the complexity of the abstract notions involved and the required mathematical background. Surveys conducted among our students showed that many of them were applying some theoretical concepts mechanically rather than developing a significant learning of them, leading to a lack of motivation and interest. To cope with this problem, we introduced a number of didactic strategies based on a constructivist approach. The main aim of the proposed strategies is to promote a more significant learning of several important FLAT topics.


Background: While mesenchymal stem cells (MSCs) exert immunomodulatory and antifibrotic effects in humans, preclinical studies also indicate that these cells can interact with host precursor cells, so as to promote tissue and organ function renewal. In human heart failure, this effect could have both cardiac and systemic vascular implications. The mechanism(s) of action by which MSCs exert favorable cardiovascular effects in human heart failure remain controversial. As heart failure is associated with endothelial dysfunction, impaired neovascularization, and diminished endothelial progenitor cell (EPC) abundance, we tested the hypothesis that MSCs simulate circulating EPCs and flow-mediated vasodilation in patients with heart failure due to dilated cardiomyopathy. Methods: We quantified EPC-colony forming units (EPC-CFUs) from peripheral blood in patients (n=16) and healthy controls (n=6), and compared these to flow-mediated vasodilation (FMD) before and 3-months after intracardiac injection of MSCs. Pati...


This paper presents a miniaturized dual-band dual-polarized broadside differential antenna with broadband and millimeter wave operation. The antenna is only printed on a single-layer substrate and has a compact structure. The radiator is a square patch with a square ring around it. The square and the ring patches provide the high and low frequencies, respectively. Four bended parasitic striplines, being placed at the four corners of the ring can increase the gain. The radiator patch is fed by the proximate coupling through split rings which is excited by a coaxial lines. Four split rings are located beside the centers of the four sides for feeding the patch differentially, which improves the port isolation and reduces the cross polarization. Sdd11 less than -10 dB covers two band of 24.2 ~ 28.2 GHz (15.3%) and 37 ~ 43.5 GHz (16.2%). The peak gain at two bands are 5.7 dBi and 7.8 dBi, respectively. The proposed antenna has a compact size of 4.1mm×4.1mm×1mm. The isolation within the working frequency band is greater than 48dB, and the cross polarization is less than -40dB. The antenna covers the 5G millimeter wave communication spectrum planned by China and can be applied to 5G millimeter wave mobile terminals.


This school-based study examined the relationship between 84 preschoolers' performance on two widely used preschool screening instruments, and teacher ratings of reading performance at the close of first grade. At prekindergarten screening 4- and 5-year-olds were evaluated with the Peabody Picture Vocabulary Test-Revised and Developmental Test of Visual-Motor Integration. Biserial correlations were computed for each test and separate appraisals of decoding and sight-word vocabulary skills. A significant positive relationship was found between PPVT-R scores and sight-word reading (r = .41, p ≤ .01). In retrospect, analysis of variance indicated that the group of first graders with poor sight-word vocabularies performed significantly lower on the PPVT-R (p = ≤ .02) than their classmates.

Abstract Background SAB is a serious, common infection. We used whole exome sequencing (WES) to examine the cumulative effect of coding variants in each gene on risk of complicated SAB in a discovery set of patients, and then evaluated the nominally significant genes in a replication set of patients using custom-capture sequencing. Methods The discovery set comprised 84 complicated SAB cases (endocarditis or bone/joint infection) frequency-matched by age (in deciles), sex, and bacterial clonal complex (CC5/30, CC8) to 84 uncomplicated SAB controls. All were white inpatients at Duke University. WES utilized Agilent SureSelect 72Mb capture kits, followed by sequencing on an Illumina HiSeq2000, alignment and base calling with a standard pipeline. The SKAT-O and EPACTS packages were used for gene-based association tests and logistic regression models with Firth bias correction, respectively. Both controlled for age, sex, and clonal complex as covariates. The replication set of 122 complicated SAB cases and 118 uncomplicated SAB controls was frequency matched by age, sex, and clonal complex. All were white Europeans collected by the Statens Serum Institute. An Agilent SureSelect 2Mb capture array captured genic sequence for 342 genes nominally associated with complicated SAB in discovery (SKAT-O P < 0.035). Sequencing and data analysis proceeded as for WES. A Bonferroni-corrected gene-based test P-value of 1.5×10–4 determined significance in the replication set. Results One gene, GLS2, was significantly associated with complicated SAB in the replication set (P = 1.2 x 10–4). The strongest single-variant association in all 342 genes was rs2657878 in GLS2 (p = 5×10−4). This variant is strongly correlated with a missense variant (rs2657879, p = 4.4x10-3) in which the minor allele (associated here with complicated SAB) has previously been shown to reduce circulating glutamine levels. Conclusion Comprehensive examination of the coding sequence for association with complicated SAB in a two-stage discovery/replication design identified a novel candidate gene. GLS2 is an interesting candidate for complicated SAB due to its role in regulating glutamine production, a key factor in activation of T-cell production. Disclosures V.

Dispersion of dissolved contaminants in fractured rocks is strongly dependent on the variability of fracture aperture. Large fracture aperture regions result in significant channeling of the fluid flow, accelerating the movement of solutes in a particular direction, which may differ locally with respect to the main flow direction from high to low hydraulic potential. This may result in very early breakthrough of the contaminants, significantly earlier than in the conventional "parallel plate" simplification of fluid flow in fractured systems. In addition, flow and transport in the low aperture regions can be orders of magnitude smaller, which has major implications for remediating contaminated fractured media. In this study we observed the transport of a nonsorbing solute in a naturally fractured rock which was characterized at very high resolution using computed tomography scanning to determine the fracture aperture distribution. We compared the observed breakthrough curve of the solute at various flow rates with the predicted breakthrough curve using the fracture's geostatistics and small perturbation analysis, as well as direct numerical simulation of flow through the fracture using the measured fracture aperture distribution. The experimentally determined fracture transmissivity and dispersivity are within a factor of 2 of those predicted using either the small perturbation approach (using the fracture geostatistics) or explicit numerical modeling of breakthrough, which differ by around 20%, indicating that the geostatistics of the fracture aperture can be used to predict the approximate shape of the breakthrough curve for a fracture.


has been extensively studied by many authors in recent years. Under various growth conditions on N, the surjectivity of T has been proven in a number of papers (see [4], [5], [7] and the references therein). Alternatively, beginning with a paper of Landesman and Lazer [61, much work has been done on the solvability of equation (1) for a certain range of values of Pf, where P is the projection of Y on the cokernel of A. Using the stable homotopy arguments, Nirenberg [9], [10], Berger [1], Mawhin [8], Podolak [11], Borisovich, Zvyagin and Sapronov [2] and others have studied equation (1). The alternative method has also been used to study equation (1) (with noncompact N too) in a series of papers by Cesari and his coworkers, Fucik, Kucera and Necas [5], and many others (cf. the survey paper by Cesari [3] and the monograph by Berger [1] for contributions of other authors). In all these papers (except in [2], [7], [11]) N is assumed to have less than linear or linear growth. In [2] and [11] the authors have studied equation (1) under the assumption that N is asymptotically linear or asymptotically Lipschitz (i.e., B in Definition 1 below is a Lipschitz map), respectively. In a series of papers Mawhin (cf. [7], [8]) has studied equation (1) with f E R(A) involving certain quasibounded maps N using his coincidence degree. In this paper we study the surjectivity of T with N either quasibounded or asymptotically quasibounded as defined below. Moreover, in case when the index of A, i(A), is zero we provide a new growth condition on PNIkerA that insures the solvability of equation (1) with these types of nonlinearities N. In the proofs of our main results we use a special case of the degree theory for

Some men with a postradiation therapy (RT) prostate‐specific antigen (PSA) recurrence will die of noncancer causes before developing metastases. Therefore, our ability to determine who would benefit from salvage hormonotherapy (HT) would be enhanced if an individual's risk of nonprostate‐cancer‐specific mortality were known.


Optimizing multivalency: Clusters of Man9 glycans which are recognized by broadly-neutralizing anti-HIV antibody 2G12 have potential as HIV vaccines. However, optimal recognition by 2G12 requires optimal clustering of glycans. Using our recently described SELMA technique (SELection with Modified Aptamers), we have developed Man9 clusters in which glycans are supported by DNA sequences selected from among 2 × 1013 variants.


In this paper we investigate the endomorphism algebras of standard cluster tilting objects in the stably 2-Calabi-Yau categories $\Sub{\Lambda_w}$ with elements $w$ in Coxeter groups in \cite{BIRSc}. They are examples of the 2-Auslander algebras introduced in \cite{I1}. Generalizing work in \cite{GLS1} we show that they are quasihereditary, even strongly quasihereditary in the sense of \cite{R}. We also describe the cluster tilting object giving rise to the Ringel dual, and prove that there is a duality between $\Sub{\Lambda_w}$ and the category $\mathcal{F}(\Delta)$ of good modules over the quasihereditary algebra. When $w = uv$ is a reduced word, we show that the 2-Calabi-Yau triangulated category $\underline{\Sub}\Lambda_v$ is equivalent to a specific subfactor category of $\underline{\Sub}\Lambda_w.$ This is applied to show that a standard cluster tilting object $M$ in $\Sub{\Lambda_w}$ and the cluster tilting object $\Lambda_w\oplus\Omega{M}$ lie in the same component in the cluster tilting graph.

This study examined the impact of two interventions on
goal attainment: Goal attainment scaling (GAS) and coaching.
Participants identified a goal they were motivated to pursue over
the course of approximately 4 weeks. Half the participants received
coaching to support their goal attainment and half did not, while
all participants were randomly assigned to either a GAS or No-GAS
condition. GAS is an interview technique in which the researcher
(1) discusses how the goal articulated connects to the
participant's "big picture" objective and (2) identifies potential
"micro" outcomes that are specific and behavioral. GAS is a
recognized outcome assessment technique originally created for the
mental health field (Kiresuk & Sherman, 1968) but has been
applied in numerous contexts over the past forty two years,
including educational settings (Schlosser, 2004). It has been
suggested that the technique may facilitate the goal attainment of
participants, and recently that GAS may work well with coaching
(Spence, 2007). This study was the first to examine the
intersection of the two techniques' influence on goal attainment.
Results indicate that the effectiveness of the interventions
depended on the type of goal articulated by participants (career
versus personal), whether it was a "big picture" or "micro" goal,
and the degree of conscientiousness of participants.


ABSTRACT An in vitro incubation study was carried out to determine the efficacy of Microlepia speluncae (MS) fronds' extract on the worm motility and viability, morphology and histopathological changes in/of Gastrothylax crumenifer. The methanolic extract of MS fronds was used for in vitro study at 1, 2, 3, 4 and 5 mg/ml concentration as test extracts. Oxyclozanide (OXY) at 1% (250 mg/25 ml) as standard control and Hedon–Fleig (H–F) salt solution as negative control. The solutions (25 ml), with 25 amphistomes each, distributed to 7 petriplates (90 mm diameter) and placed in an incubator with 5% CO2 at 37°C. The motility of control and treated flukes was observed at regular time intervals, 0, 10, 15, 30 and 60 min respectively with specific score 3, 2, 1, 0 for motility. Relative Motility assay and LC50 were determined by probit regression analysis. In vitro incubation study revealed death of all trematodes, lethal at 10 min incubation time at 5 mg/ml concentration, indicated RM value is 0, very much effective than Oxyclozanide, RM value was 0. 05. The LC50 was determined as 3.666. The worms subjected to in vitro trials were studied under Scanning Electron Microscope and Light Microscope for significant morphological changes.


A sparse algebraic multigrid method is studied as a cheap and accurate way to compute approximations of Schur complements of matrices arising from the discretization of some symmetric and positive definite partial differential operators. The construction of such a multigrid is discussed and numerical experiments are used to verify the properties of the method.


Green technology is one of the major aspects in order to reduce the global pollution content from manufacturing industries. There is a need to investigate the different available tools for high-speed micromilling process of advanced alloys to achieve desired surface finish without traditional coolants. In this chapter, tool wear investigation of uncoated and PVD-coated AlTiN, TiAlN tungsten carbide end mills in high-speed micro-end milling of alpha + beta Ti-6Al-4V ELI titanium alloy (Grade 23) under dry cutting conditions was presented. A comparison for machining performance with the three tools is reported. Cutting force analysis was done under the considered machining input parameters for evaluating the tool condition. Tool wear observation was done by SEM analysis. EDX analysis was performed to know the material constituents and wear mechanisms on the cutting tool tip. It is found that diffusion, oxidation, adhesive and abrasive wear mechanisms were the major phenomena taking place on the cutting edge of micro end mills. From the comparison of cutting tools for machining Grade 23 titanium alloy, it was found that TiAlN tools performed better than AlTiN and uncoated tungsten carbide tools.


In LTE downlink multiple-input multiple-output (MIMO), eigen based beamforming (EBB) is a promising appr-oach for single-user scenario, while block diagonalization based beamforming (BDBF) eliminates intra-cell interferences significantly for multi-user scenario. However, both of them neglect inter-cell interferences which may lead system performance degradation. This paper presents an interference suppression based beamforming (ISBF) scheme to suppress inter-cell interferences. We first introduce interference suppression matrix (ISM) into EBB and BDBF to propose a novel beamforming matrix construction method. Then the ISM reporting scheme is discussed to support ISBF, and a precoded uplink pilot based (PUPB) reporting scheme is presented exploiting the channel reciprocity in TDD system. Finally, the simulation results are provided using dynamic system level simulator. Our results show that ISBF improves cell average and cell edge spectral efficiency significantly compared with traditional EBB and BDBF.


Usually blind people use white canes which are very limited in its ability to provide navigation assistance to the user and cannot easily detect obstacles. Mobility of visually impaired people is limited by their inability to perceive their surroundings. Therefore the purpose of this project is to build a navigation system that will be able to guide a visually impaired person safely and with ease, in an indoor and outdoor environment. This goal has been realized through the use of an ultrasonic device to determine the range of obstacles and also a microcontroller to act accordingly. The system includes a warning system through voice rendering and through generation of vibration.


Abstract It is shown that a sequence of pairs of locally polar polyhedra makes it possible to construct piecewise-affine approximation to the spherical Gauss map and to construct convergent pointwise approximations to mean and Gauss curvatures of regular surfaces. Any DC surface (representable as a difference of convex functions, A. D. Alexandrov, 1949) possesses a second differential and a tangent paraboloid almost everywhere, hence approximation by dual polyhedra allows us to approximate the curvature of such surfaces.


Nano-compact disks (Nano-CDs) with 400 Gbit/in2 topographical bit density (nearly three orders of magnitude higher than commercial CDs) have been fabricated using nanoimprint lithography. The reading and wearing of such Nano-CDs have been studied using scanning proximal probe methods. Using a tapping mode, a Nano-CD was read 1000 times without any detectable degradation of the disk or the silicon probe tip. In accelerated wear tests with a contact mode, the damage threshold was found to be 19 μN. This indicates that in a tapping mode, both the Nano-CD and silicon probe tip should have a lifetime that is at least four orders of magnitude longer than that at the damage threshold.


Last Term, in FCC v. NextWave Personal Communications, Inc. ("NexiWave"),1 the U.S. Supreme Court held that the Federal Communications Commission (the FCC or "Commission") could not revoke wireless communications licenses held by a debtor-in-possession under the Bankruptcy Code ("Code"), following that debtor's failure to make timely payments owed for their purchase.2 The Code, the Court held, prevented the agency from canceling licenses issued pursuant to its administrative authority, notwithstanding the licensee's violation of a "full and timely payment" requirement established by regulation.3 The NextWave decision settled a five-year legal dispute that produced divergent decisions from a bankruptcy court, a federal district court, the FCC itself, and two federal courts of appeals. The decision is significant in its particulars: the holding concerned the allocation of valuable licenses to use wireless spectrum. Yet the case also has much broader ramifications for the treatment of government agencies in bankruptcy proceedings. Specifically, the Court's opinion signals three related principles that may impose significant limitations on the power of administrative agencies participating in bankruptcy proceedings. First, agencies are subject to the strictures of the Bankruptcy Code, even when they act in a regulatory capacity; second, bankruptcy law may prohibit the enforcement of a wide array of license conditions; and third, the Bankruptcy Code trumps agency licensing rules. At the same time, however, the opinion leaves in place lower court decisions limiting bankruptcy jurisdiction over administrative action. Just as the NextWave adjudication delimits the authority of administrative agencies in the bankruptcy


Negative differential characteristics in the relations between photoinduced currents and forward bias voltages are investigated considering accumulations of photogenerated carriers in a storage layer on a GaAs/GaAlAs multi‐quantum well structure. The nonlinear characteristics become obvious when the storage layer is an InAs/GaAs short period superlattice and can be observed at 300 K under weak photoexcitations (e.g., 2.5 mW/cm2). On the other hand, the phenomenon is extremely reduced in the case of a storage layer of an InGaAs alloy or InAs, and disappears without the storage layer. These results correspond with the differences of carrier lifetime in the storage layer. The enhanced negative differential characteristics can be due to the smaller trap densities and the larger electron mobility in the storage layer of the InAs/GaAs short period superlattice. Finally, the applications of the characteristics to the selectivity functions of visual neurons are discussed.


One measure to handle the expected increase of road traffic in the future is to use traffic management systems. After a phase of research which is almost finished, the authors are in the second phase of system development, testing and introduction. One of the expected aims of the European research programme PROMETHEUS was "unprecedented safety". However, the results so far differ greatly in their assessment. Some of the already implemented systems such as collective dynamic safety and diversion signing on autobahns have had a beneficial effect on traffic safety especially by reducing serious casualties and fatalities. On the other hand the authors find systems where the aims and the success for traffic safety will be greatly dependent on driver behaviour and human interaction with technology. The report gives a critical overview about some of the realized and some realizable safety effects of traffic management systems. Among other things, it contains a critical comparison between analyses of already installed dynamic safety and diversion signing facilities with a focus on traffic safety (e.g. accident trends) and the costs entailed by installation and operation. The authors also discuss the 10 requirements of the German Traffic Safety Council for safe traffic management systems. These are: (1) Collective dynamic safety and diversion signing and flexible signing systems; (2) Radio traffic systems; (3) Traffic relocation through road taxes; (4) Logistic of hazardous substance transport; (5) Rescue services; (6) Road and weather conditions; (7) Travel planning; (8) Acceptance, costs and operational safety; (9) Safety has to be an essential criterion of system assessment; and (10) Fields of implementation.
