A Two-Party Identity-Based Key Agreement Protocol with Explicit Authentication (2012)

A two-message two-party key agreement protocol with explicit authentication provides perfect forward secrecy. Digital signatures can usually be used as providing explicit authentication for a key agreement protocol. Shim proposed an efficient identity-based signature scheme using bilinear pairings; however, he did not give a formal security proof for it. In this paper, we present a formal security proof for Shim's signature scheme. Using Shim's signature scheme as building blocks, we propose a new two-party identity-based key agreement protocol with explicit authentication. The proposed protocol satisfies a set of desirable security properties. Compared with the related protocols, the proposed protocol has distinct advantages in terms of security and computational efficiency.
Wettability Alteration in High-Temperature and High-Salinity Carbonate Reservoirs (2013)

Summary The goal of this work was to change the wettability of a carbonate rock from mixed-wet toward water-wet at high temperature and high salinity. Three types of surfactants in dilute concentrations (&lt;0.2 wt%) were used. Initial surfactant screening was performed on the basis of aqueous stability at these harsh conditions. Contact-angle experiments on aged calcite plates were conducted to narrow the list of surfactants, and spontaneous-imbibition experiments were conducted on field cores for promising surfactants. Secondary waterflooding was carried out in cores with and without the wettability-altering surfactants. It was observed that most but not all surfactants were aqueous-unstable by themselves at these harsh conditions. Dual-surfactant systems, mixtures of a nonionic and a cationic surfactant, increased the aqueous stability. Some of the dual-surfactant systems proved effective for wettability alteration and could recover could recover 70 to 80% OOIP (original oil in place) during spontaneous imbibition. Secondary waterflooding with the wettability-altering surfactant increased the oil recovery over the waterflooding without the surfactants (from 29 to 40% of OOIP).
Microscopic magnetic resonance elastography (μMRE) (2005)

Magnetic resonance elastography (MRE) was extended to the microscopic scale to image low-frequency acoustic shear waves (typically less than 1 kHz) in soft gels and soft biological tissues with high spatial resolution (34 micromx34 micromx500 microm). Microscopic MRE (microMRE) was applied to agarose gel phantoms, frog oocytes, and tissue-engineered adipogenic and osteogenic constructs. Analysis of the low-amplitude shear wave pattern in the samples allowed the material stiffness and viscous loss properties (complex shear stiffness) to be identified with high spatial resolution. microMRE experiments were conducted at 11.74 T in a 56-mm vertical bore magnet with a 10 mm diameterx75 mm length cylindrical space available for the elastography imaging system. The acoustic signals were generated at 550-585 Hz using a piezoelectric transducer and high capacitive loading amplifier. Shear wave motion was applied in synchrony with the MR pulse sequence. The field of view (FOV) ranged from 4 to 14 mm for a typical slice thickness of 0.5 mm. Increasing the agarose gel concentration resulted in an increase in shear elasticity and shear viscosity. Shear wave motion propagated through the frog oocyte nucleus, enabling the measurement of its shear stiffness, and in vitro shear wave images displayed contrast between adipogenic and osteogenic tissue-engineered constructs. Further development of microMRE should enable its use in characterizing stiffer materials (e.g., polymers, composites, articular cartilage) and assessing with high resolution the mechanical properties of developing tissues.
Concepts for Planning Urban Greening since 1850s (2005)

Urban greening, urban forestry and urban green structure planning all look at a city as a unit andintend to improve the status of green space in the city. Even though they are new terms, their concepts haveevolved over a rather long period. This paper presents a historical review of western concepts for urbangreening since the 1850s. The first aim is to establish an overview of how the urban greening concept hasdeveloped and what the relationships are between the historical concepts and urban greening, urban forestryand urban green structure planning today. The secondary purpose is to understand some key issues for urbangreening through the examination of historical precedents. Based on a literature review, the paper presentsseveral historical concepts for urban greening rampart area planning, park system, green belts, greenwedges and greenways. The new concept of urban green structure is also introduced. Each concept is defined.The social background and the influence on city development are described. The review shows that theconcept of urban greening has a long history, parallel with the development of the city planning concepts.The scope of urban greening has become larger over the past years. The functions of urban green space havechanged from single-purpose to multi-purpose. The study indicates that historical concepts may still giveinspiration in todays urban greening process.
Two-dimensional liquid crystal laser array (2008)

A two-dimensional liquid crystal (LC) laser array has been demonstrated by photopumping a single LC sample using a lenslet array consisting of plano-convex microlenses. A 5 x 5 array of LC lasers (displaying evidence of mutual coherence) spaced by 1 mm inactive regions has been generated, which could be combined to yield a single monomode output and allows an almost 50-fold increase in energy density in comparison to a single-focus LC cavity. Furthermore, we have demonstrated how the individual and recombined emission spectra vary with different sample topologies and how polydomain samples can be used to generate a multiwavelength laser emission.
Accuracy Comparison of Roadway Earthwork Computation between 3D and 2D Methods (2013)

This study aims to calculate the earthwork volume in 3D method that has been seldom used before in roadway engineering, and to reconfirm the feasibility of average-end-area method for earthwork volume that is widely used in literature. After reviewing the related studies and comparing various CAD packages, the analysis of accuracy difference between 3D method and average-end-area method is conducted. It shows that in average-end-area method the critical value of interval distance between two consecutive cross sections is 30m. It also shows that the Change Rate of Cut-Fill (CRCF) value, an index firstly proposed to represent the cut-fill variance frequency associated with roadway terrain, alignment and profile design, has no significant impacts on the accuracy of 2D result. It is concluded that the 3D method could be easily used in practice with the CAD software. Meanwhile, average-end-area method with less than the critical interval distance between two consecutive cross sections can guarantee the earthwork calculation accuracy.
[Treatment of anterior uveitis with 5-fluorouracil]. (1992)

Filtering surgery with use of 5-fluorouracil (5FU) was performed in 5 eyes (4 patients) with inflammatory glaucoma to prevent filtering bleb scarring. Postoperative injections of 5FU were given once or twice a day, according to the degree of anterior chamber inflammation. Complete remission of the uveitis was achieved in all 5 eyes after 7-14 days of postoperative injections of 5FU. There were no recurrences of uveitis during a minimum of 8 months of follow-up.
Reusability of immunoaffinity columns for determination of fumonisins in maize (1999)

Eighteen maize samples were assayed for fumonisin B1 (FB1) and B2 content by immunoaffinity column coupled with high performance liquid chromatography (HPLC). The FumoniTest columns were used once for the isolation of fumonisins (single-use column method). In the second part of the assay the columns were regenerated. After elution with methanol, PBS solution was left on the column for one day at room temperature to regenerate the columns (regenerated column method). The efficiency of columns regenerated twice was tested by determining FB, recovery and the reproducibility of the determinations. The recovery rate of FB1 proved to be 82% by the single-use column method (RSD: 5.7%) and 82.6% (RSD: 5.6 %) by the regenerated column method; 500-8,000 ng FB1 loaded onto the columns did not affect column performances. Nearly identical values were obtained when the FB1 content of fumonisin-containing maize samples was determined by both methods. The results indicate that the FumoniTest columns can be regenerated by the method applied at least twice without decrease in column performance. The fumonisin affinity, capacity and specificity of the regenerated columns were not changed. Thus, columns regenerated in this way can be used for determining the fumonisin content of maize samples at least three times.
Sexual differentiation in decapod crustaceans: role of the androgenic gland (1997)

Summary In male crustaceans—unlike vertebrates—the endocrine and gametogenic functions are clearly separated into distinct organs, the androgenic gland and the testis, respectively. The androgenic gland is thought to be the exclusive source of hormone responsible for sex-differentiation and sexual characteristics in crustaceans. Information on this unique crustacean organ is revised with respect to its structure, secretion and role in the regulation of the expression of sexual characteristics, and intersexuality. Several decapod models are presented for research on sexual differentation in higher crustaceans.
<title>Discussion of evaluating methods for photorejuvenation</title> (2007)

Photorejuvenation is a promising technique for esthetics. But evaluating approach for efficacy of photorejuvenation is relatively behind demand. In this study, after discussion of current techniques, a novel evaluating method for photorejuvenation which combines reflectance and fluorescence spectroscopy is proposed. Laser induced autofluorescence spectroscopy can be used to detect biochemical information from depth of skin. Tristimulus values which reflect the color of skin can be obtained by diffuse reflectance spectroscopy. So combination of the reflectance and fluorescence spectrum is expected to be a promising tool for evaluating efficacy of photorejuvenation.
Integrating MPI and nanothreads programming model (2003)

This paper presents a prototype runtime system that integrates MPI, used on distributed memory systems, and nanothreads programming model (NPM), a programming model for shared memory multiprocessors. This integration does not alter the independence of the two models, since the runtime system is based on a multilevel design that supports each of them individually but offers the capability of combining their advantages. Existing MPI codes can be executed without any changes, codes for shared memory machines can be used directly, while the concurrent use of both models is easy. Major feature of the runtime system is portability, as it is based exclusively on calls to MPI and Nthlib, a user-level threads library that has been ported to several operating systems. The runtime system supports the hybrid-programming model (MPI+OpenMP), providing also a solution for better load balancing in MPI applications. Moreover, it extends the AN and the multiprogramming functionality of the NPM on clusters of multiprocessors and can support an extension of the OpenMP standard on distributed memory multiprocessors.
Ray tracing with polarization parameters (1990)

Incorporating polarization parameters into the lighting model can enhance the physical realism of images rendered with a ray tracer. Polarization effects can be important in certain scenes, and the difference in rendering even simple scenes with and without proper treatment of polarization can be striking. All light waves possess a state of polarization, which changes almost every time light reflects off a material surface. A single reflection partially polarizes and may even completely polarize previously unpolarized light. Polarization influences the rendering of a scene because the reflected radiant intensity depends largely on the incident light waves's polarization state. E. Wolf's (1959) coherence matrix formalism of polarization has been incorporated into the Torrance-Sparrow reflectance model. This combination allows elegant quantitative derivations of the altered polarization state of light upon reflection in a ray tracer. Comparisons of identical scenes rendered with a conventional ray tracer and the ray tracer presented incorporating a polarization model show that the present method renders specular interobject reflections more accurately with respect to reflected radiance and color.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effects of Low-Dose and Long-Term Treatment with Erythromycin on Interleukin-17 and Interleukin-23 in Peripheral Blood and Induced Sputum in Patients with Stable Chronic Obstructive Pulmonary Disease (2016)

Erythromycin was beneficial and reduced airway inflammation in COPD patients. Underlying mechanisms may involve inhibition of IL-17 and IL-23 mediated airway inflammation. COPD patients treated with erythromycin for 6 months experienced improved exercise capacity. Finally, treatment for 12 months may be more effective than treatment for 6 months.
Computational learning reveals coiled coil-like motifs in histidine kinase linker domains (1998)

The recent rapid growth of protein sequence databases is outpacing the capacity of researchers to biochemically and structurally characterize new proteins. Accordingly, new methods for recognition of motifs and homologies in protein primary sequences may be useful in determining how these proteins might function. We have applied such a method, an iterative learning algorithm, to analyze possible coiled coil domains in histidine kinase receptors. The potential coiled coils have not yet been structurally characterized in any histidine kinase, and they appear outside previously noted kinase homology regions. The learning algorithm uses a combination of established sequence patterns in known coiled coil proteins and histidine kinase sequence data to learn to recognize efficiently this coiled coil-like motif in the histidine kinases. The common appearance of the structural motif in a functionally important part of the receptors suggests hypotheses for kinase regulation and signal transduction.
Key Role of Src Kinase in S100B-induced Activation of the Receptor for Advanced Glycation End Products in Vascular Smooth Muscle Cells (2006)

The receptor for advanced glycation end products (RAGE) and its ligands have been implicated in the activation of oxidant stress and inflammatory pathways in vascular smooth muscle cells (VSMCs) leading to the initiation and augmentation of atherosclerosis. Here we report that non-receptor Src tyrosine kinase and the membrane protein caveolin-1 (Cav-1) play a key role in the activation of RAGE by S100B in VSMCs. S100B increased the activation of Src kinase and tyrosine phosphorylation of caveolin-1 in VSMCs. A RAGE-specific antibody blocked both these effects. An inhibitor of Src kinase, PP2, significantly blocked S100B-induced activation of Src kinase, mitogen-activated protein kinases, transcription factors NF-kappaB and STAT3, superoxide production, tyrosine phosphorylation of Cav-1, VSMC migration, and expression of the pro-inflammatory genes monocyte chemotactic protein-1 and interleukin-6. Cholesterol depletion also inhibited S100B-induced effects indicating the requirement for intact caveolae in RAGE-specific signaling. Nucleofection of either a Src dominant negative mutant, or a Cav-1 mutant lacking the scaffolding domain, or Cav-1 short hairpin RNA significantly reduced S100B-induced inflammatory gene expression in VSMCs. Furthermore, VSMCs derived from insulin-resistant and diabetic db/db mice displayed increased RAGE expression, Src activation, and migration compared with those from control db/+ mice. The RAGE antibody blocked enhanced migration in db/db cells. These studies demonstrate for the first time that, in VSMCs, Src kinase and Cav-1 play important roles in RAGE-mediated inflammatory gene expression and migration, key events associated with diabetic vascular complications.
Evolution of composition framework in a distributed system toolkit (2004)

Network Centric Information Infrastructure (NCII) is a toolkit of prefabricated software components together with a composition framework for integration and experimentation. Typical distributed system applications of a toolkit such as NCH can be applied to air traffic management, shop floor control and in-flight connection to Internet. The composition framework has gone though through three generations of changes in the past five years and it is a good illustration of a paradigm shift from object-oriented architecture, through component-based architecture to service-based architecture.
Variability of Bacterial Vaginosis Over 6- to 12-Month Intervals (2006)

About one fifth of women with normal flora develop BV over a given 6- to 12-month interval, and the modifiable risk factors of cervicitis and lack of monogamy contribute to the development of BV.
Autonomous proximity awareness of Bluetooth devices (2005)

This paper focuses on designing autonomous device discovery algorithms for Bluetooth networks. We first extend the conventional asymmetric Bluetooth link model to three point-to-point symmetric link models. Their performances are compared analytically. To achieve proximity awareness among a group of Bluetooth devices, three control information exchanging methods are also proposed. Combining with the three link models, this gives 9 possible variants of autonomous device discovery algorithm. A comprehensive comparative study based on these 9 variants is then carried out using Bluehoc simulator.
Transcriptome analyses of the human retina identify unprecedented transcript diversity and 3.5 Mb of novel transcribed sequence via significant alternative splicing and novel genes (2013)

To our knowledge, this is the first application of RNA capture to perform large-scale validation of novel transcriptome features. In total, these analyses provide extensive detail about a previously uncharacterized level of transcript diversity in the human retina.
Chemistry of Organophosphonate Scale Growth Inhibitors: 2. Structural Aspects of 2‐Phosphonobutane‐1,2,4‐Tricarboxylic Acid Monohydrate (PBTC.H<sub>2</sub>O) (2005)

Industrial water systems often suffer from undesirable inorganic deposits, such as calcium carbonate, calcium phosphate(s), magnesium silicate, and others. Synthetic water additives such as phosphonates and phosphonocarboxylates are the most important and widely utilized scale inhibitors in a plethora of industrial applications. The design of efficient and cost-effective inhibitors, as well as the study of their structure and function at the molecular level are important areas of research. This study reports the crystal and molecular structure of PBTC (PBTC = 2-phosphonobutane-1,2,4-tricarboxylic acid), one of the most widely used scale inhibitors in the cooling water treatment industry. Triclinic PBTC monohydrate crystallizes in the P 1 space group with cell dimesions, a =7.671(1) A, b = 8.680(1) A, c = 9.886(1) A, alpha = 65.518(2) deg, beta = 71.683(2) deg, gamma = 76.173(2) deg, V = 564.20(11) A(3), and Z = 2. Bond distances in the -PO(3) moiety are 1.4928(10) A for the P=O double bond and 1.5294(10) A and 1.5578(10) A for the two -P-O(H) groups. P-C and C-O bond lengths fall in the normal range. A network of hydrogen bonds are formed between the water molecule of crystallization, the -P-OH and the -COOH groups.
Multi-valued simulation of digital circuits (2002)

This paper presents a new method for multi-valued simulation of digital circuits based on calculation of Boolean derivatives on structural binary decision diagrams (SBDD) (or structural alternative graphs). A procedure for calculation of the maximum of Boolean derivative on SBDDs as the basis for multi-valued simulation is described. The method is applicable for component level representations of digital circuits where as components arbitrary subcircuits (macros) instead of gates are considered. No dedicated model library for representing multi-valued behaviour of components is needed. Instead of dedicated multi-valued models, generic ones in the form of SBDDs are used. Experimental data to demonstrate the advantages of the new approach are provided.

Rapid magnetic resonance quantification on the brain: Optimization for clinical usage (2008)

A method is presented for rapid simultaneous quantification of the longitudinal T(1) relaxation, the transverse T(2) relaxation, the proton density (PD), and the amplitude of the local radio frequency B(1) field. All four parameters are measured in one single scan by means of a multislice, multiecho, and multidelay acquisition. It is based on a previously reported method, which was substantially improved for routine clinical usage. The improvements comprise of the use of a multislice spin-echo technique, a background phase correction, and a spin system simulation to compensate for the slice-selective RF pulse profile effects. The aim of the optimization was to achieve the optimal result for the quantification of magnetic resonance parameters within a clinically acceptable time. One benchmark was high-resolution coverage of the brain within 5 min. In this scan time the measured intersubject standard deviation (SD) in a group of volunteers was 2% to 8%, depending on the tissue (voxel size = 0.8 x 0.8 x 5 mm). As an example, the method was applied to a patient with multiple sclerosis in whom the diseased tissue could clearly be distinguished from healthy reference values. Additionally it was shown that, using the approach of synthetic MRI, both accurate conventional contrast images as well as quantification maps can be generated based on the same scan.
