A novel supershaped slot-loaded printed dipole antenna with broadside radiation for dual-band WLAN applications

A novel planar dipole antenna featuring super-shaped wing contour was designed for wireless local area network operation. The flairs of the antenna are mathematically defined by the supershape formula and one concave slot is symmetrically introduced in each flair in order two frequency bands to be formed. The substrate of the antenna is elliptically shaped and a differential feeding structure is used. The antenna exhibits very attractive performance characteristics. The bands excited fully meet the requirements of the most widely used IEEE 802.11 standards. The symmetrical characteristics of the antenna and the balanced feeding mechanism yield extremely low cross-polarization. Furthermore, the efficiency levels of the antenna achieved are higher than 98%. Also, unidirectional broadside radiation patterns are for the first time obtained from a wideband dipole antenna due to the successful introduction of a ground plane.
Structures and properties of the novel peapods — One dimensional C60O polymer encapsulated in single-walled carbon nanotubes

The structures and electronic properties of the novel peapods — one dimensional C60O polymer encapsulated in single-walled carbon nanotubes (C60O@SWCNT) are investigated using self-consistent field crystal orbital methods based on the density-functional theory. It is found that the inter-wall distance between the two constituents is the most important factor impacting the structure shape and stability of the peapods. The mobilities of charge carrier and the Young moduli for the C60O@SWCNTs are larger than those for the corresponding pristine SWCNTs.
Fluidics in Microwave Components

Thanks to the efforts of various research groups over the past decade in the area of tunable microwave passive components, the idea of tunability has become very well established within the RF/microwave community [1]-[5]. Many different designs have shown that tunable microwave components can improve the performance of a radio system in many ways. The tunability of microwave components has been realized using semiconductor devices (such as varactors or p-i-n diodes) and microelectromechanical systems (MEMS) devices. While these offer many advantages, such as high-quality factor and high-bandwidth operation (mainly for MEMS devices) and fast switching speeds (mainly for varactors and p-i-n diodes), they come with two major drawbacks.
QuantumMemory for Retrieval of stored photons from-type atomic ensembles involving coupling of transverse modes

in Danish Resumé på dansk Overordnet handler denne bacheloropgave om hvorledes kvantetilstanden for en lyspuls kan gemmes i, og senere udlæses fra, en gas af atomer, hvorved sidstnævnte fungerer som en kvantehukommelse. Dette hører ind under feltet kvanteoptik, som netop beskæftiger sig med lysets kvanteegenskaber, som de manifesterer sig i vekselvirkningen med atomer. Kvantehukommelse udgør en fundamental byggesten i mange kvanteinformationsteknologiske anvendelser, herunder kvantecomputeren, hvorfor arbejdet med at forstå denne komponents virkemåde, samt hvordan dens begrænsende faktorer bedst håndteres, er et vigtigt led i bestræbelserne på at konstruere effektive kvanteinformationssystemer. En kvantehukommelse baseret på en gas af atomer kan konstrueres på en række forskellige måder. Denne opgave beskæftiger sig med det tilfælde, hvor interaktionen mellem lys og atomer er bestemt ved en Hamiltonoperator af strålesplitter-typen. Dette tilfælde er allerede blevet analyseret i ganske stor detaljegrad i [3, 5], men til forskel fra disse studier vil udledningerne i denne opgave blive foretaget under antagelse af en cylindrisk symmetrisk fordeling af atomerne i gasskyen; en sådan antagelse medfører, at der forekommer kobling mellem forskellige transverse modes. Formålet med denne opgave er at arbejde hen imod en forståelse af, hvor høj grad af pålidelighed der kan opnås i forbindelse med udlæsning fra en kvantehukommelse af ovenfor beskrevne type. Mere specifikt vil et formelt udtryk for effektiviteten af udlæsning fra kvantehukommelsen blive udledt. Ud fra dette udtryk er det muligt at foretage en numerisk bestemmelse af systemets egenmodes og de respektive effektiviteter, hvormed de kan udlæses. I opgaven redegøres ydermere for den bagvedliggende kvantemekaniske formalisme og de approksimationer, der anvendes for at simplificere udledningerne.
Interactively Exploring Time-Oriented Data

Time is an important data dimension with distinct characteristics that is common across many application domains. This demands specialized methods in order to support proper analysis and visualization to explore trends, patterns, and relationships in different kinds of time-oriented data. The human perceptual system is highly sophisticated and specifically suited to spot visual patterns. For this reason, visualization is successfully applied in aiding these tasks and to date a variety of different visualization methods for timeoriented data exist. However, these methods could be improved by accounting for the special characteristics of time. The main aim of our current research is to account for the complex structures of time in visual representations, analysis, and the visualization process. Especially important are interaction methods that aid analysts when dealing with time-oriented data in visualization systems.
Structural Basis and Specificity of Acetylated Transcription Factor GATA1 Recognition by BET Family Bromodomain Protein Brd3

ABSTRACT Recent data demonstrate that small synthetic compounds specifically targeting bromodomain proteins can modulate the expression of cancer-related or inflammatory genes. Although these studies have focused on the ability of bromodomains to recognize acetylated histones, it is increasingly becoming clear that histone-like modifications exist on other important proteins, such as transcription factors. However, our understanding of the molecular mechanisms through which these modifications modulate protein function is far from complete. The transcription factor GATA1 can be acetylated at lysine residues adjacent to the zinc finger domains, and this acetylation is essential for the normal chromatin occupancy of GATA1. We have recently identified the bromodomain-containing protein Brd3 as a cofactor that interacts with acetylated GATA1 and shown that this interaction is essential for the targeting of GATA1 to chromatin. Here we describe the structural basis for this interaction. Our data reveal for the first time the molecular details of an interaction between a transcription factor bearing multiple acetylation modifications and its cognate recognition module. We also show that this interaction can be inhibited by an acetyllysine mimic, highlighting the importance of further increasing the specificity of compounds that target bromodomain and extraterminal (BET) bromodomains in order to fully realize their therapeutic potential.
Changes in Peripheral Refractive Profile after Orthokeratology for Different Degrees of Myopia

Abstract Purpose: The purpose of this study was to evaluate the effect of orthokeratology for different degrees of myopia correction in the relative location of tangential (FT) and sagittal (FS) power errors across the central 70° of the visual field in the horizontal meridian. Methods: Thirty-four right eyes of 34 patients with a mean age of 25.2 ± 6.4 years were fitted with Paragon CRT (Mesa, AZ) rigid gas permeable contact lenses to treat myopia (−2.15 ± 1.26D, range: −0.88 to −5.25D). Axial and peripheral refraction were measured along the central 70° of the horizontal visual field with the Grand Seiko WAM5500 open-field auto-refractor. Spherical equivalent (M), as well as tangential (FT) and sagittal power errors (FS) were obtained. Analysis was stratified in three groups according to baseline spherical equivalent: Group 1 [MBaseline = −0.88 to −1.50D; n = 11], Group 2 [MBaseline = −1.51 to −2.49D; n = 11], and Group 3 [MBaseline = −2.50 to −5.25D; n = 12]. Results: Spherical equivalent was significantly more myopic after treatment beyond the central 40° of the visual field (p < 0.001). FT became significantly more myopic for all groups in the nasal and temporal retina with 25° (p ≤ 0.017), 30° (p ≤ 0.007) and 35° (p ≤ 0.004) of eye rotation. Myopic change in FS was less consistent, achieving only statistical significance for all groups at 35° in the nasal and temporal retina (p ≤ 0.045). Conclusions: Orthokeratology changes significantly FT in the myopic direction beyond the central 40° of the visual field for all degrees of myopia. Changes induced by orthokeratology in relative peripheral M, FT and FS with 35° of eye rotation were significantly correlated with axial myopia at baseline.
Representation Learning in Large Attributed Graphs

Graphs (networks) are ubiquitous and allow us to model entities (nodes) and the dependencies (edges) between them. Learning a useful feature representation from graph data lies at the heart and success of many machine learning tasks such as classification, anomaly detection, link prediction, among many others. Many existing techniques use random walks as a basis for learning features or estimating the parameters of a graph model for a downstream prediction task. Examples include recent node embedding methods such as DeepWalk, node2vec, as well as graph-based deep learning algorithms. However, the simple random walk used by these methods is fundamentally tied to the identity of the node. This has three main disadvantages. First, these approaches are inherently transductive and do not generalize to unseen nodes and other graphs. Second, they are not space-efficient as a feature vector is learned for each node which is impractical for large graphs. Third, most of these approaches lack support for attributed graphs. To make these methods more generally applicable, we propose a framework based on the notion of attributed random walk that is not tied to node identity and is instead based on learning a function $\Phi : \mathrm{\rm \bf x} \rightarrow w$ that maps a node attribute vector $\mathrm{\rm \bf x}$ to a type $w$. This framework serves as a basis for generalizing existing methods such as DeepWalk, node2vec, and many other previous methods that leverage traditional random walks.
Inverse Kinematics of Some General 6R/P Manipulators

We develop an algorithm that solves the inverse kinematics of general serial 2RP3R, 2R2P2R, 3RP2R and 6R manipulators based on the HuPf algorithm. We identify the workspaces of the 3-subchains of the manipulator with a quasi-projective variety in $\mathbb{P}^7$ via dual quaternions. This allows us to compute linear forms that describe linear spaces containing the workspaces of these 3-subchains. We present numerical examples that illustrate the algorithm and show the real solutions.
Identification of two transcripts of AMLI/ETO‐fused gene in t(8;21) leukemic cells and expression of wild‐type ETO gene in hematopoietic cells

The t(8; 21) is a common chromosomal abnormality, preferentially associated with acute leukemia showing features of myeloid differentiation. Recently, two genes–AMLI which has a unique runt domain, and ETO (MTG8)–have been isolated from the chromosomal breakpoint. In this study, we isolated and identified two fused transcripts from a leukemic cell line carrying t(8; 21). AMLI and ETO were fused at the same position in these transcripts. One of the transcripts codes a unique domain, including two zinc finger domains and three proline‐ and one leucine‐rich region. The other transcript codes only for one proline‐ and leucine‐rich region but lacks zinc finger domains. We demonstrated by polymerase chain reaction (PCR) analysis that I) these two transcripts are consistently expressed in leukemic cells with t(8; 21) obtained from patients and 2) expression of AMLI was not restricted to the particular stage of hematopoietic differentiation but was present in all hematopoietic cells investigated. We also provide evidence that two wild types of ETO transcripts containing the region of the ETO gene in fused transcripts are expressed in hematopoietic cells from different lineages. The widespread expression of AMLI and ETO in hematopoietic cells suggests a fundamental role of these proteins in hematopoiesis. Furthermore, the differences in the carboxy termini of ETO may modulate the activity of fused proteins resulting from the chromosomal translocation t(8; 21). © 1995 Wiley‐Liss, Inc.
Interactive comment on “ Storage and stability of organic carbon in soils as related to depth , occlusion within aggregates , and attachment to minerals ”

Conceptual models suggest that stability of or- ganic carbon (OC) in soil depends on the source of plant litter, occlusion within aggregates, incorporation in organo- mineral complexes, and location within the soil profile. Den- sity fractionation is a useful tool to study the relevance of OC stabilization in aggregates and in association with min- erals, but it has rarely been applied to full soil profiles. We aim to determine factors shaping the depth profiles of phys- ically unprotected and mineral associated OC and test their relevance for OC stability across a range of European soils that vary in vegetation, soil types, parent material, and land use. At each of the 12 study sites, 10 soil cores were sam- pled to 60 cm depth and subjected to density separation. Bulk soil samples and density fractions (free light fractions - fLF, occluded light fractions - oLF, heavy fractions - HF) were analysed for OC, total nitrogen (TN), 13 C, and 1 14 C. Bulk samples were also incubated to determine CO2 evolution per g OC in the samples (specific mineralization rates) as an in- dicator for OC stability. Depth profiles of OC in the light fraction (LF-OC) matched those of roots for undisturbed grassland and forest sites, suggesting that roots are shaping the depth distribution of LF-OC. Organic C in the HF declined less with soil depth than LF-OC and roots, especially at grassland sites. The de- crease in 1 14 C (increase in age) of HF-OC with soil depth was related to soil pH as well as to dissolved OC fluxes. This indicates that dissolved OC translocation contributes to the formation of subsoil HF-OC and shapes the 1 14 C profiles. The LF at three sites were rather depleted in 14 C, indi- cating the presence of fossil material such as coal and lig- nite, probably inherited from the parent material. At the other sites, modern 1 14 C signatures and positive correlations be- tween specific mineralization rates and fLF-OC indicate the fLF is a potentially available energy and nutrient source for subsurface microorganisms throughout the profile. Declining specific mineralization rates with soil depth confirm greater stability of OC in subsoils across sites. The overall impor- tance of OC stabilization by binding to minerals was demon- strated by declining specific mineralization rates with in- creasing contributions of HF-OC to bulk soil OC, and the low 1 14 C values of HF-OC. The stability of HF-OC was greater in subsoils than in topsoils; nevertheless, a portion of HF-OC was active throughout the profile. While quanti- tatively less important than OC in the HF, consistent older ages of oLF-OC than fLF-OC suggest that occlusion of LF- OC in aggregates also contributes to OC stability in subsoils. Overall, our results indicate that association with minerals is the most important factor in stabilization of OC in soils, irre- spective of vegetation, soil type, and land use.
Internal initiation of translation on the vesicular stomatitis virus phosphoprotein mRNA yields a second protein

In vitro translation of a mixture of the vesicular stomatitis virus (VSV) polyadenylated mRNAs yielded a previously undetected protein with a molecular weight of approximately 7,000 (7K protein). Hybrid-arrested translation demonstrated that both the 7K protein and the VSV phosphoprotein (P protein) were encoded by the P protein message. Immunoprecipitation of the 7K protein with monoclonal antiserum directed against the P protein indicated that the two products were encoded in the same open reading frame. A protein of approximately the same size was immunoprecipitated from cytoplasmic extracts of VSV-infected cells by both the polyclonal and monoclonal antisera, and it is likely that it was a previously unrecognized viral gene product. Translational mapping of the P protein mRNA in vitro indicated that the 7K protein was encoded in the 3' one-third of the sequence. The synthesis of the 7K protein in vitro was unaffected by hybrid arrest conditions which blocked the 5' two-thirds of the mRNA and inhibited synthesis of the P protein. These results imply that the ribosomes bind and initiate translation internally on the P protein mRNA at a site located hundreds of nucleotides downstream from the capped 5' end.

Complaints of pain after use of handcuffs should not be dismissed

EDITOR—Handcuffs are commonly used to restrain prisoners. It is not unusual for them to be applied in violent circumstances and for the prisoner to struggle. This can lead to overtightening of the handcuffs and considerable trauma to the structures around the wrist. We have recently seen fractures, lacerations, and injuries to the radial, ulnar, and median nerves (table). This is probably the tip of the iceberg, as many people with such injuries fail to attend for assessment, follow up, or investigation. View this table: Data …
Insulin sensitivity in response to a single resistance exercise session in apparently healthy individuals

Background: Regular resistance exercise completed for a number of weeks has been shown to increase insulin sensitivity and reduce the risk of diabetes-related complications. However, the acute responses to resistance exercise have not been adequately investigated in relation to training frequency. Aim: To investigate the changes to insulin sensitivity in apparently healthy individuals following a single session of unaccustomed resistance exercise. Subjects and methods: Ten sedentary, apparently healthy individuals performed a baseline oral glucose tolerance test and maximal strength testing. Participants then performed a single session of moderate-high intensity resistance exercise which was followed by 4 consecutive days of oral glucose tolerance testing, for which participants replicated their initial diet. Mean estimated insulin sensitivity change scores from baseline values and their 95% confidence intervals were compared to the previously determined values for a clinically meaningful change. Results: Two participants were identified as having hyperinsulinemia and their data were therefore removed from the main analysis. There was a clinically meaningful increase in insulin response (mean >7237 pmol·I−1·120 min−1) on all days following the exercise session and a clinically meaningful increase in glucose response (mean >81 mmol·I−1·120 min−1) on only the 3rd day following exercise. These changes suggest a potentially adverse short-term effect. Additionally, the 2 individuals with hyperinsulinemia displayed more extreme results. Conclusion: These results suggest that insulin sensitivity may be impaired following a single session of unaccustomed resistance exercise for approximately 4 days in healthy untrained, older individuals. Further research is required for individuals with hyperinsulinemia.
Breakdown strength of solid dielectrics in liquid nitrogen

The objective of this research was to determine if a relationship could be found between dielectric strength and other properties of electrical insulating materials in the medium of liquid nitrogen on an empirical basis by using variables predicted by basic theory. A simple equation of the form E=A+Blog (rhov/xir tandelta) to predict the dielectric strength of a solid insulating material in liquid nitrogen medium has been proposed. The equation requires the values of volume resistivity (rhov), relative permittivity (xir) and loss tangent (tandelta) in the medium of liquid nitrogen, which may be obtained easily by low voltage non-destructive measurements. The values of electric strength calculated using this equation for Crepe paper, Kraft paper, varnished paper, pressboard, presspahn, mica, bakelite and asbestos are quite in agreement with the experimentally measured values. It is expected that the equations obtained will help the designers as a handy tool for quick estimation of breakdown strength of solid dielectrics dipped in liquid nitrogen.
Sorption of polynuclear aromatic hydrocarbons by sediments and soils.

The sorption of pyrene, 3-methylcholanthrene, 7,12-dimethylbenz(a)anthracene, and dibenzanthracene on 14 soil and sediment samples exhibiting a wide range of physicochemical properties was studied. The equilibrium Freundlich constants and linear partition coefficients for each compound were highly correlated with the organic carbon content of the soils/sediments tested. No other significant correlations with soil/sediment properties were observed. The sorption constants when normalized to organic carbon content of the substrate predicted the octanol-water partition coefficients for the compounds tested. A highly significant negative correlation was observed between log substrate and log water solubility for these compounds. Experimental values of the water solubility and octanol-water partition coefficients for the four compounds are reported.
Measuring the Impact of Stock Exchange Rules on Volatility and Error Transmission - The Case of European Cross-Listed Equities

This paper investigates the relationship between spillover effects and stock market regulations for a sample of cross-listed European firms. Using LaPorta et al.’s (1998) stock exchange regulatory classification we identify firms that have cross-listed on foreign exchanges with either tougher, weaker or similar accounting disclosure, bankruptcy and shareholder protection rules. We then use the GARCH approach suggested by Karolyi (1995) and Engle and Kroner (1995) to estimate volatility and error transmission for our sample of cross-listed equities, taking into account regulatory differences between exchanges. Our results show how differences in stock exchange rules can influence spillovers between foreign cross-listed equities and the respective market indices. Accounting disclosure rules also seem to have less of an effect on cross-listed share volatility transmission than do differences in shareholder and bankruptcy protection rules.
