Trusted P2P computing environments with role-based access control (2007)

A P2P computing environment can be an ideal platform for resource-sharing services in an organisation if it provides trust mechanisms. Current P2P technologies offer content-sharing services for non-sensitive public domains in the absence of trust mechanisms. The lack of sophisticated trust mechanisms in the current P2P environment has become a serious constraint for broader applications of the technology although it has great potential. Therefore in this work an approach for securing transactions in the P2P environment is introduced, and ways to incorporate an effective and scalable access control mechanism – role-based access control (RBAC) – into current P2P computing environments has been investigated, proposing two different architectures: requesting peer-pull (RPP) and ultrapeer-pull (UPP) architectures. To provide a mobile, session-based authentication and RBAC, especially in the RPP architecture, lightweight peer certificates (LWPCs) are developed. Finally, to prove the feasibility of the proposed ideas, the RPP and UPP RBAC architectures are implemented and their scalability and performance are evaluated.
Toroidal coil winding machines making the best choice (2002)

The lack of knowledge regarding the toroidal coil winding equipment hampers the growth of the toroid as first choice for transformers, inductors and other electrical applications. The author discusses the different components of toroidal coil winding machine and their functions; the different types of toroidal coil winding equipment, their application and comparative advantages/disadvantages; and general mathematical calculations required for selecting the appropriate toroidal coil winding equipment.
Photodistributed erythema multiforme: paclitaxel-related, photosensitive conditions in patients with cancer. (2009)

Paclitaxel (Taxol) is an intravenously administered antineoplastic agent derived from the yew tree, Taxus brevifolia, whose mechanism of action involves inhibition of mitosis. Some of the mucocutaneous reactions to the drug that have been observed include alopecia, mucositis, hypersensitivity reactions (with erythema and urticaria), nail changes, changes occurring at intravenous sites, and radiation recall dermatitis. Less commonly, acral erythema, erythema multiforme, pustular dermatitis, and scleroderma-like changes have been described. A female patient who was receiving adjuvant weekly paclitaxel for the treatment of intraductal breast carcinoma developed photodistributed erythema multiforme and onycholysis after sun exposure to the affected areas. Including this woman, paclitaxel-associated photosensitve conditions have only been reported in 9 female oncology patients: onycholysis (5), erythema multiforme and onycholysis (2), photo-recall phenomenon (1), and subacute cutaneous lupus erythematosus (1). The patients were either receiving treatment for breast carcinoma (8) or lung cancer (1). The skin lesions developed on sun-exposed areas, usually after the patient had received several weekly doses of paclitaxel, and resolved following discontinuation of the drug. Several of the patients were subsequently able to receive additional cycles of paclitaxel without recurrence of their drug-associated photosensitive conditions by concurrently using photoprotection to prevent additional sun exposure to the previously affected sites during treatment.

A Vessel Detection Method Using Compact-Array HF Radar (2017)

A compact-array high-frequency surface wave radar equipped with two crossed-loop/monopole receiving antennas has been established for vessel detection. Using two compact antennas of the same design, this system can obtain two extremely similar sets of radar range-Doppler spectra over the same period. To detect vessel targets efficiently, the spectra of two antennas are enhanced by performing a principle component analysis. A wavelet-based approach is then applied to suppress clutter and reduce noise. The signal-to-noise ratios and signal-to-clutter ratios of the echoes are thus improved. Finally, an adaptive threshold is used to extract targets. The real radar data detection results are compared with Automatic Identification System data as well as those from the conventional ordered-statistic constant false alarm rate method. The feasibility and the validity of method proposed here are thus demonstrated.
Über Bildung und Darstellung von <i>d</i>‐Glucosamin aus Fructose und Ammoniak (1953)

Abstract Bei der Umsetzung von Fructose mit wäßrigem Ammoniak sowie insbesondere auch mit wasserfreiem flüssigen Ammoniak entsteht d ‐ Glucosamin. Die Identifizierung erfolgte durch das analytische und chromatographische Verhalten sowie durch Darstellung des nach Kupplung mit Phenylisocyanat und Ringschluß mit Essigsäure erhaltenen 1‐Phenyl‐4‐[ d ‐arabo‐tetraoxybutyl]‐imidazolons‐(2) und durch Überführung in die N ‐Carbobenzoxy‐Verbindung. Die biochemischen Zusammenhänge der Hexosamin‐Bildung werden erörtert.
Thermal-neutron scattering lengths and capture by even calcium isotopes (1989)

Neutron-diffraction patterns have been measured for isotopically enriched powder samples of calcite using both steady-state and pulsed-neutron techniques. Greatly enhanced precision over previous work has been achieved for $^{40}\mathrm{Ca}$ and $^{44}\mathrm{Ca}$, while the results for $^{42}\mathrm{Ca}$, $^{43}\mathrm{Ca}$, and $^{48}\mathrm{Ca}$ represent new data. The coherent scattering lengths deduced from these measurements have been employed in a more definitive analysis of primary electric-dipole gamma rays from thermal-neutron capture. In three cases ${(}^{40}$Ca, $^{42}\mathrm{Ca}$, and $^{48}\mathrm{Ca}$) the estimates from a spherical optical-model formulation of the direct-capture mechanism are in agreement with the experimental cross sections. In $^{44}\mathrm{Ca}$ the theory overestimates the measured cross sections on average by about 60%; this divergence can be explained by considering the modifications to the theory due to collective vibrations of the $^{44}\mathrm{Ca}$ core.

High Quality Shadows for Real-time Surface Visualization (2016)

This thesis describes the implementation of a shadowing system able to produce hard shadows. Shadow mapping is the most common real-time shadowing algorithm but it suffers from severe aliasing artifacts and self-shadowing effects. Different advanced techniques based on Shadow Mapping are implemented in this thesis with the objective of creating accurate hard shadows. First, an implementation based on Cascaded Shadow Maps is presented. This technique improves the visual quality of shadow mapping by using multiple smaller shadow maps instead of a large one. The technique addresses the fact that objects near the viewer require a higher shadow map resolution than objects far away. The second technique presented is Sub-pixel Shadow Mapping. By storing information about occluding triangles in the shadow map this technique is able to produce accurate hard shadows with sub-pixel precision. Both methods can be combined in order to improve the resulting shadow quality. Finally, a collection of advanced biasing techniques that minimize the self-hadowing artifacts generated by shadow mapping are presented. The final implementation achieves real-time performances with considerably improved quality compared to standard shadow mapping.
Finite conformal modules over N=2,3,4 superconformal algebras (2001)

In this paper we continue the study of representation theory of formal distribution Lie superalgebras initiated by Cheng and Kac [Asian J. Math. 1, 181–193 (1997); 2, 153–156 (1998) (erratum)]. We study finite Verma-type conformal modules over the N=2, N=3 and the two N=4 superconformal algebras and also find explicitly all singular vectors in these modules. From our analysis of these modules we obtain a complete list of finite irreducible conformal modules over the N=2, N=3 and the two N=4 superconformal algebras.
A coupled filtering method to solve feature-motion decorrelation in speckle tracking (2010)

In speckle tracking, feature-motion decorrelation is a problem that makes feature tracking results unable to represent the underlying tissue deformation. In this paper, we propose a coupled filtering method to address the feature-motion decorrelation problem. After explicitly modeling image variations caused by tissue deformation, we filter the image before tissue deformation and the warped image after tissue deformation with a pair of filters, respectively. Theoretical derivation show that the two filtered images are identical to each other. Since the coupled filtering method keeps tissue deformation parameters, feature-based tracking is able to accurately estimate the parameters of underlying tissue deformation. Experiments in elastography studies show that our method is superior over previous methods.
An FPGA implementation of high speed and area efficient double-precision floating point multiplier using Urdhva Tiryagbhyam technique (2015)

Floating-point arithmetic is ever-present in computer systems. All most all computer languages has supports a floating-point number types. Most of the computer compilers called upon floating-point algorithms from time to time for execution of the floating-point arithmetic operations and every operating system must be react virtually for floating-point exceptions like underflow and overflow. The double-precision floating arithmetic is mainly used in the digital signal processing (filters, FFTs) applications, numerical applications and scientic applications. The double-precision floating arithmetic operations are the addition, the subtraction, the multiplication, and the division. Among the all arithmetic operations, multiplication is widely used and most complex arithmetic operation. The double-precision (64-bit) floating point number is divide into three fields, Sign field, Exponent field and Mantissa field. The most significant bit of the number is a sign field and it is a 1-bit length, next 11-bits represents the exponent field of the number and remaining 52-bits are represents the mantissa field of the number. The double-precision floating-point multiplier requires a large 52×52 mantissa multiplications. The performance of the double-precision floating number multiplication mainly depends on the area and speed. The proposed work presents a novel approach to decrease this huge multiplication of mantissa. The Urdhva Tiryagbhyam technique permits to using a smaller number of multiplication hardware compared to the conventional method. In traditional method adding of the partial products are separately done and it takes more time in comparison with the proposed method. In proposed method the partial products are concurrently added with the multiplication operaton and it can reduce the time delay. The double-precision floating multiplier is implemented using Verilog HDL with Xilinx ISE tools on Virtex-5 FPGA.
An obesogenic diet during mouse pregnancy modifies maternal nutrient partitioning and the fetal growth trajectory (2013)

In developed societies, high-sugar and high-fat (HSHF) diets are now the norm and are increasing the rates of maternal obesity during pregnancy. In pregnant rodents, these diets lead to cardiovascular and metabolic dysfunction in their adult offspring, but the intrauterine mechanisms involved remain unknown. This study shows that, relative to standard chow, HSHF feeding throughout mouse pregnancy increases maternal adiposity (+30%, P<0.05) and reduces fetoplacental growth at d 16 (-10%, P<0.001). At d 19, however, HSHF diet group pup weight had normalized, despite the HSHF diet group placenta remaining small and morphologically compromised. This altered fetal growth trajectory was associated with enhanced placental glucose and amino acid transfer (+35%, P<0.001) and expression of their transporters (+40%, P<0.024). HSHF feeding also up-regulated placental expression of fatty acid transporter protein, metabolic signaling pathways (phosphoinositol 3-kinase and mitogen-activated protein kinase), and several growth regulatory imprinted genes (Igf2, Dlk1, Snrpn, Grb10, and H19) independently of changes in DNA methylation. Obesogenic diets during pregnancy, therefore, alter maternal nutrient partitioning, partly through changes in the placental phenotype, which helps to meet fetal nutrient demands for growth near term. However, by altering provision of specific nutrients, dietary-induced placental adaptations have important roles in programming development with health implications for the offspring in later life.
Beyond DNA Repair: DNA-PK Function in Cancer (2014)

Although DNA-PK is classically considered a component of damage response, recent findings illuminate damage-independent functions of DNA-PK that affect multiple tumor-associated pathways and provide a rationale for the development of novel therapeutic strategies.
Stochastic processes constrain the within and between host evolution of influenza virus (2018)

The evolutionary dynamics of influenza virus ultimately derive from processes that take place within and between infected individuals. Here we define influenza virus dynamics in human hosts through sequencing of 249 specimens from 200 individuals collected over 6290 person-seasons of observation. Because these viruses were collected from individuals in a prospective community-based cohort, they are broadly representative of natural infections with seasonal viruses. Consistent with a neutral model of evolution, sequence data from 49 serially sampled individuals illustrated the dynamic turnover of synonymous and nonsynonymous single nucleotide variants and provided little evidence for positive selection of antigenic variants. We also identified 43 genetically-validated transmission pairs in this cohort. Maximum likelihood optimization of multiple transmission models estimated an effective transmission bottleneck of 1-2 genomes. Our data suggest that positive selection is inefficient at the level of the individual host and that stochastic processes dominate the host-level evolution of influenza viruses.
Defining the heparin-binding domain of antithrombin (1994)

Antithrombin is a serine protease inhibitor that participates in the inactivation and removal from the circulation of thrombin and a variety of other procoagulant serine proteases. Antithrombin is also the major plasma cofactor of heparin which exerts its therapeutic effect primarily through its ability to substantially increase the rate of inactivation by antithrombin of the procoagulant serine proteases. Binding of heparin to antithrombin is thus believed to be a prerequisite for this rate enhancement effect. Heparin binding to antithrombin is mediated by a well-defined unique heparin pentasaccharide sequence. Interaction between this pentasaccharide sequence and antithrombin induces a conformational change in antithrombin, an alteration that appears to be sufficient to explain the enhanced ability of antithrombin to inhibit factor Xa and related serine proteases, but not thrombin. Heparin species with longer polysaccharide chains appear to be required in order to enhance the inhibition of thrombin by antithrombin. This may be because the enhancement of this reaction requires that heparin interacts simultaneously with both the antithrombin and the thrombin molecules. This review describes the interactions between heparin and antithrombin, focusing on the antithrombin residues which are involved in the binding of heparin. The role of the heparin-induced conformational change in enhancing serine protease inhibition by antithrombin is also explored. Then, based on available data, an hypothesis is proposed to explain the mechanisms by which heparin accelerates the rate of inactivation by antithrombin of the various serine proteases.
W-band on-wafer load-pull measurement system and its application to HEMT characterization (2002)

An on-wafer large-signal characterization system has been developed for W-band frequency applications. The system is computer-controlled and employs a high-precision electromechanical W-band tuner. Its application to obtaining constant output power and gain contours as well as power saturation characteristics of submicron InP-based HEMTs is demonstrated at 77 GHz and 102 GHz.
Effect of Intermittent Light on Broilers Reared under Moderate Temperature Conditions (1978)

Commercial broilers reared under an intermittent-lighting regime produced a significantly better feed conversion than broilers reared under a continuous-lighting regime. Body weight gain was not significantly affected by light treatment. However, the number of breast trims, as recorded under commercial processing plant inspection procedures, was significantly higher for broilers reared under an intermittent-lighting regime than for those reared under a continuous-lighting regime in which the light intensity was changed during each 24-hr period.
Problems in the care management of the aging patient: legal, financial and practical implications. (2000)

The graying of America poses many challenges to the dental professional. As the population ages, most dental practices are experiencing growth in percentage of older people served. The dental practitioner must be on the alert to special problems associated with the treatment of the older patient. Failure to identify these common concerns may result in patient non-compliance, failure to achieve treatment goals and heightened risk of malpractice. In addition, dental professionals who are aware of the multiplicity of factors that impact the aging process can better promote their own successful aging. This article focuses on identifying some of the key "hidden" issues typically facing older patients which can adversely impact dental treatment; and, practical techniques for managing these problem areas. Also covered are common financial and social concerns associated with aging and suggestions for how dental professionals can avoid complications from compounding in their own lives.
A novel HF fishbone antenna with vee-element (2009)

A novel HF fishbone antenna with V-shape dipoles is introduced. Long V-shape dipoles instead of short linear ones are used as elements to increase the directivity. NEC-2 (Numerical Electromagnetic Code Version 2) is involved to numerically evaluate the radiation characteristics of this new fishbone antenna with two different arm lengths, 12 m and 20 m, respectively. Parameters such as open angle of V-shape dipole, loading resistance, spacing between adjacent dipole and total number of dipoles are optimized according to the simulating results. It is found that the directivity of a fishbone antenna with V-type elements is about 2-5 dB higher at higher frequency band than that of a traditional fishbone antenna. It is also found that the advantages of a traditional fishbone antenna, such as low side-lobe and wide operating band are well reserved in the new design.
