Thermochromic Coatings for Intelligent Architectural Glazing (2008)

Thermochromic glazing is a type of intelligent glazing; one where the properties of the glazing change according to some external stimulus. More particularly a thermochromic window is a device that changes its transmission and reflectance properties at a critical temperature (Tc). Atthis specific temperature the material undergoes a semi-conductor to metal transition. At temperatures lower than Tc the window lets all of the solar energy that hits it through. At emperatures above Tc the window reflects the infra-red portion of solar energy. In such a way thermochromic windows may help reduce air conditioning and heating costs leading to more energy efficient buildings. This review details the nature of the semi-conductor to metal transition and indicates how substitutional doping within a crystal lattice can be used to manipulate and fine tune the critical temperature. Also detailed is the underlying science and methodologies so far employed in the production of thermochromic thin films.

Effect of Analogy Instructions with an Internal Focus on Learning a Complex Motor Skill (2013)

This study examined the effects of an analogy in learning breaststroke swimming. Two groups of participants had 20 lessons on how to increase their stroke length. The participants in the experimental condition received an analogy with an internal focus of attention. Inter-limb coordination showed qualitative changes in this group: a greater increase in swimming efficiency (i.e., a coordination closer to anti-phase [−50° before learning and −125° after] and a 10% decrease in the time spent in-phase). The findings showed that an internal focus of attention induced by analogy could be beneficial in improving the quality of inter-limb swimming coordination.
Inflammatory Gene Expression in Cerebral Ischemia and Trauma (1997)

This review summarized evidence in support for the case that ischemia elicits an inflammatory condition in the injured brain. The inflammatory condition consists of cells (neutrophils at the onset and later monocytes) and mediators (cytokines, chemokines, others). It is clear that de novo upregulation of proinflammatory cytokines, chemokines and endothelial-leukocyte adhesion molecules in the brain follow soon after the ischemic insult and at a time when the cellular component is evolving. The significance of the inflammatory response to brain ischemia is not fully understood. Evidence is emerging in support of the possibility that the acute inflammatory reaction to brain ischemia may be causally related to brain damage. This evidence includes: 1) the capacity of cytokines to exacerbate brain damage; 2) the capacity of specific cytokine antagonists such as IL-1ra to reduce ischemic brain damage; 3) that depletion of circulating neutrophils reduces ischemic brain injury; 4) and that antagonists of the endothelial-leukocyte adhesion interactions (e.g., anti-ICAM-1) reduce ischemic brain injury. However, it should be kept in mind that cytokines were also argued to provide beneficial effects in brain injury as inferred from studies with TNF-receptor knock-out mice (p55 and p75 knock-out), which display increased sensitivity to brain ischemia, and the capacity of IL-1 to elicit the state of ischemic tolerance upon repeated administration. Nevertheless, the recent revelation on the capacity of ischemia to induce acute inflammation in the brain provides a new and fertile ground for new explorations for novel therapeutic agents that could confine the neuronal damage that follows ischemia. Furthermore, many of the genes that are upregulated by ischemia have growth-promotion capacity and therefore raise the possibility that such gene products may be useful in counteracting brain damage by enhancing repair and establishing compensatory mechanisms that enhance histological and functional recovery.
Anti-f Met-Leu-Phe: similarities in fine specificity with the formyl peptide chemotaxis receptor of the neutrophil. (1982)

We have prepared antisera in both rabbits and rats against f Met-Leu-Phe conjugated to a variety of carrier proteins. Over 40 peptides with widely varying reactivity for the neutrophil formylpeptide receptor have been tested for their ability to bind to rabbit antibody raised against fMLP10-BSA. Structure-activity studies of peptides structurally related to f Met-Leu-Phe demonstrate that the N-formyl group is mandatory for maximum antibody binding activity. Methionine in position 1 and phenylalanine in position 3 are found to confer maximum binding activity. Stereoselectivity of the antibody-combining site also has been demonstrated. Comparison of the ability of the peptides to bind to the antibody receptor with their reactivity for the neutrophil has demonstrated a strong correlation in the rank order of reactivity of the numerous synthetic peptides: for the alpha NH2-acyl group, r = 0.94; for position 1, r = 0.90; for position 2, r = 0.97; and for position 3, r = 0.78. This strong correlation is seen across species lines with both rabbit and rat antibodies. Significant differences, however, in the specificity of the antibody and neutrophil receptors are seen at the carboxyl terminus of phenylalanine, and beyond the phenylalanine ring, r = 0.29. In addition, bacterial chemotactic factor-enriched butanol extracts from Escherichia coli culture filtrates can also bind to anti-f Met-Leu-Phe, affording additional evidence for the similarity in the structure of the bacterial chemotactic factor to the synthetic chemotactic peptides.
Key Challenges of Military Tactical Networking and the Elusive Promise of MANET Technology (2006)

Mobile ad hoc networks (MANETs) are considered by many as fundamental to realizing the global information grid (GIG) and the vision of network-centric warfare. Indeed, a fully realized MANET would be powerful in enabling highly mobile, highly responsive, and quickly deployable tactical forces. However, significant technical challenges remain before this realization is viable. Addressing these deficiencies is a significant task that will require the invention and adoption of new technology. The goal of this article is not to declare these capabilities impossible to achieve. Rather, it is to manage the expectation of the capabilities achievable in the foreseeable future through edification on the technical difficulties standing between current technology and the desired capabilities. This article provides an overview of the military MANET problem space, describing the ideal military MANET solution. Several deficiencies are highlighted that exist between MANET technologies and the desired capability. Identified technical issues include system-level architecture, routing (both interior and exterior), management, security, and medium access control (MAC), with an emphasis on the former two areas

Effect of order-disorder transition on magnetic properties of high silicon-iron single crystals (1985)

Using high silicon-iron single crystals containing around 6.5 wt. % silicon, the quenching temperature dependence of the saturation magnetization, the magnetocrystalline anisotropy constant, and the magnetostriction constants were measured at room temperature. The saturation magnetization and the anisotropy constant of the crystals with 4.9–6.0 wt. % silicon quenched into oil from 1100 °C showed decreases of up to 12 and 80%, respectively, compared to crystals cooled slowly from 1100 °C, while the saturation magnetostriction constants λ100 and λ111 increased for quenched crystals. The decreases in the saturation magnetizations and the anisotropy constants and the increases in the saturation magnetostriction constants for the quenched crystals were correlated with decreases in an order parameter calculated from x-ray measurements.
Performance Evaluation of Routing Method Based on Neighboring Node Information in WMN (2015)

Because of developments of wireless technologies in recent years, wireless mesh networks have been focused. Our research group have proposed routing method Multiple Branch Collection Routing (MBCR) for wireless mesh networks to reduce control communications by using location information and new defined address. We have evaluated the performance of MBCR that has been extended in this paper. As results of simulations, we confirmed that MBCR with the new parameters achieved better performance than existing approaches.
Logic programming semantics using a compact data structure (1986)

A fixpoint semantics is given for logic programming using domain theory, with undefined as one truth value, allowing negation, and arbitrary data structures. This generalizes the conventional semantics, and agrees with it on 'successes' for Horn clause programs. Consequences of requiring the data structure to be a compact topological space and the given relations to be continuous are investigated, extending results in the last chapter of Lloyd's book.
HLA-A2 and -A24-restricted glypican-3-derived peptide vaccine induces specific CTLs: Preclinical study using mice (2008)

We previously reported that glypican-3 (GPC3) is uniquely overexpressed in human hepatocellular carcinoma and melanoma and that it is an ideal tumor antigen for immunotherapy in mouse models. We recently identified both HLA-A24 (A*2402) and H-2Kd-restricted GPC3298-306 (EYILSLEEL) and HLA-A2 (A*0201)-restricted GPC3144-152 (FVGEFFTDV), both of which can induce GPC3-reactive cytotoxic T cells (CTLs). The present study was a preclinical study in a mouse model that was conducted in order to design an optimal schedule for clinical trial of GPC3-derived peptide vaccine. When BALB/c mice were intradermally vaccinated at the base of the tail with Kd-restricted GPC3298-306 peptide mixed with incomplete Freund's adjuvant (IFA), the peptide-specific CTLs were induced. But the peptide alone could not induce peptide-specific CD8+ T cells. Furthermore, proteomic analyses showed that IFA protected the peptide against degradation in the human serum. Peptide-reactive CTLs were induced by peptide vaccine in a dose-dependent manner. In addition, at least two vaccinations with a single dose >10 microg were needed for the induction of GPC3298-306-specific CTLs. But repeated vaccination with a lower dose of GPC3298-306 did not induce peptide-specific CTLs. Similarly, induction of an Ag-specific immune response by HLA-A2 GPC3144-152 depended on the dose administered. The results of this study suggested that IFA is one of the indispensable adjuvants for peptide-based immunotherapy, and that the immunological effect of peptide vaccines depends on the dose of peptide injected.
A multiuser 3D Web browsing system (1998)

The Virtual Realty Modeling Language sets an open-standard file format for designing 3D multimedia and shared virtual worlds on the Internet. VRML was originally designed to support the interaction of multiple participants in the World Wide Web environment, that is, to network virtual worlds via hyperlinks. The development of VRML has spurred broad research on distributed multiuser VR systems. We describe SharedWeb, a 3D Web browsing system that was designed and implemented to support interaction among clients in the existing Web environment. We begin by describing the methodologies and mechanisms used to achieve seamless integration with the Web environment, then we summarize the SharedWeb system implementation. We present some experimental results that show the effects of different frame rates and threshold values on system performance, and conclude with discussions of two virtual worlds currently supported by the system.
The 3D-Kernel DM+V/W algorithm: Using wind information in three dimensional gas distribution modelling with a mobile robot (2010)

In this paper we present a statistical method to build three-dimensional gas distribution maps from gas sensor and wind measurements obtained with a mobile robot in uncontrolled environments. The particular contribution of this paper is to introduce and evaluate an algorithm for 3D statistical gas distribution mapping, that takes into account airflow information. 3D-Kernel DM+V/W algorithm uses a multivariate Gaussian weighting function to model the information provided by the gas sensors and an ultrasonic anemometer. The proposed algorithm is evaluated with respect to the ability of the obtained models to predict unseen measurements. The results based on 15 trials with a mobile robot in an indoor environment show improvements in the model performance when using the 3D kernel DM+V/W algorithm. Moreover the model is able to adapt to the dynamical changes of the environment learning the hyper-parameter from the sensors readings.
Self-assembled CaP-based hybrid nanoparticles to enhance gene transfection efficiency <i>in vitro</i> and <i>in vivo</i>: beneficial utilization of PEGylated bisphosphate and nucleus locating signal (2018)

Calcium phosphate (CaP) nanoparticles have been considered as a non-viral gene delivery vehicle, but the weakness of inconsistent and low transfection efficiencies is limited to its progress. In order to overcome these weaknesses and to improve the consistency and efficiency of CaP nanoparticles, a pH-sensitive core-shell system mPEG-Pam/CaP/HMGB1/pDNA hybrid nanoparticle was prepared. The PEGylated pamidronate (mPEG-Pam) segment forms a hydrophilic outer shell for enhancing the stability of nanoparticles and HMGB1 was used as a nucleus locating signal (NLS) to improve the efficiency of nucleus importation and gene expression. The formed hybrid nanoparticles presented small particle size and desired serum stability with the assistance of the mPEG-Pam outer layer. The results of RFP fluorescence intensity analysis in HepG2 cells showed that the hybrid nanoparticles exhibited higher transfection capability with the help of HMGB1 as compared to that of the nanoparticles without the HMGB1. More importantly, after intravenous injection in tumor-bearing S180 nude mice, the hybrid nanoparticles specifically accumulated into the tumor regions by EPR effect, leading to efficient gene expression and anti-tumor effects in vivo. We concluded that the hybrid nanoparticles possessed potential as a safe and effective pDNA delivery system.
Study on the Compatibility of Asphaltic Crude Oil with the Electric Desalting Demulsifiers (2003)

The compatibility of asphaltic crude oil with demulsifiers in the electric desalting process was studied in this paper. The test result showed that asphaltene in crude oil causes the raising and abnormal of crude viscosity. Structure and character of asphaltic molecules make them easily gather and associate with each other at the oil/water interface and finally form a viscoelastic interfacial film of great mechanical strength. This not only interferes with the salt transfer from the oil to the aqueous phase, but also hinders the aggregation of the water drops, and thus affects desalting process of crudes. Several kinds of demulsifier series synthesized were used to investigate desalting and dewatering efficiencies in the electric desalting process. It was found that with the same initiator each emulsifier series had got an optimal proportion of propylene oxide (PO) and initiator. There also exists an ideal value of desalting and dewatering efficiency when demulsifiers were polymerized with ethylene oxide (EO) because demulsifiers polymerized with EO will improve its hydrophile−lipophile property. The phenolic resin series were compatible with asphaltic crude in desalting efficiency, whereas the polyhydric alcohol series were more efficient in dewatering efficiency. The recombination of phenolic resin demulsifiers with polyhydric alcohol demulsifiers can give a satisfactory result to asphaltic crude oil in both desalting and dewatering efficiency.
Design for Efficiency Optimization and Voltage Controllability of Series–Series Compensated Inductive Power Transfer Systems (2013)

Inductive power transfer (IPT) is an emerging technology that may create new possibilities for wireless power charging and transfer applications. However, the rather complex control method and low efficiency remain the key obstructing factors for general deployment. In a regularly compensated IPT circuit, high efficiency and controllability of the voltage transfer function are always conflicting requirements under varying load conditions. In this paper, the relationships among compensation parameters, circuit efficiency, voltage transfer function, and conduction angle of the input current relative to the input voltage are studied. A design and optimization method is proposed to achieve a better overall efficiency as well as good output voltage controllability. An IPT system design procedure is illustrated with design curves to achieve a desirable voltage transfer ratio, optimizing between efficiency enhancement and current rating of the switches. The analysis is supported with experimental results.
A Short and Efficient Synthesis of (±)‐Modhephene by a Stereoelectronically‐Controlled Ene‐Reaction (1981)

Abstract (±)‐Modhephene ( 6 ) has been synthesized from the easily available trimethylpentalenone 1 in 6 steps in 26% overall yield (Scheme 2) . The remarkably smooth 1,4‐addition/enolate trapping 1 → 2 and subsequent selenoxide elimination after oxidation furnished the key intermediate 3 which underwent an expedient and highly stereoselctive intramolecular ene ‐reaction to give the propellane 4 , readily convertible to (±)‐ 6 .
Effects of material properties of femoral hip components on bone remodeling (1992)

Bone loss around femoral hip stems is one of the problems threatening the long-term fixation of uncemented stems. Many believe that this phenomenon is caused by reduced stresses in the bone (stress shielding). In the present study the mechanical consequences of different femoral stem materials were investigated using adaptive bone remodeling theory in combination with the finite element method. Bone-remodeling in the femur around the implant and interface stresses between bone and implant were investigated for fully bonded femoral stems. Cemented stems (cobalt-chrome or titanium alloy) caused less bone resorption and lower interface stresses than uncemented stems made from the same materials. The range of the bone resorption predicted in the simulation models was from 23% in the proximal medial cortex surrounding the cemented titanium alloy stem to 76% in the proximal medial cortex around the uncemented cobalt-chrome stem. Very little bone resorption was predicted around a flexible, uncemented "iso-elastic" stem, but the proximal interface stresses increased drastically relative to the stiffer uncemented stems composed of cobalt-chrome or titanium alloy. However, the proximal interface stress peak was reduced and shifted during the adaptive remodeling process. The latter was found particularly in the stiffer uncemented cobalt-chrome-molybdenum implant and less for the flexible iso-elastic implant.
The network computing architecture and system: an environment for developing distributed applications (1988)

A description is given of the network computing architecture (NCA), an object-oriented framework for developing distributed applications in a heterogeneous computing environment. The network computing system (NCS) is a portable implementation of that architecture that runs on Unix and other systems. The object-oriented approach is examined. The network interface definition language (NIDL) is then introduced and discussed. Network data representation is considered. The NCS NIDL compiler, the location broker, and the NCA/RPC protocol and NCS implementation are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A <i>KAS2</i> cDNA complements the phenotypes of the <i>Arabidopsis fab1</i> mutant that differs in a single residue bordering the substrate binding pocket (2002)

The fab1 mutant of Arabidopsis is partially deficient in activity of beta-ketoacyl-[acyl carrier protein] synthase II (KAS II). This defect results in increased levels of 16:0 fatty acid and is associated with damage and death of the mutants at low temperature. Transformation of fab1 plants with a cDNA from Brassica napus encoding a KAS II enzyme resulted in complementation of both mutant phenotypes. The dual complementation by expression of the single gene proves that low-temperature damage is a consequence of altered membrane unsaturation. The fab1 mutation is a single nucleotide change in Arabidopsis KAS2 that results in a Leu337Phe substitution. The Leu337 residue is conserved among plant and bacterial KAS proteins, and in the crystal structures of E. coli KAS I and KAS II, this leucine abuts a phenylalanine whose imidazole ring extends into the substrate binding cavity causing the fatty acid chain to bend. For functional analysis the equivalent Leu207Phe mutation was introduced into the fabB gene encoding the E. coli KAS I enzyme. Compared to wild-type, the Leu207Phe protein showed a 10-fold decrease in binding affinity for the fatty acid substrate, exhibited a modified behavior during size-exclusion chromatography and was severely impaired in condensation activity. These results suggest that the molecular defect in fab1 plants is a structural instability of the KAS2 gene product induced by insufficient space for the imidazole ring of the mutant phenylalanine residue.
