Formation mechanism of a microscale domain and effect on transport properties in strainedVO2thin films onTiO2(001) (2014)

We investigated film thickness dependence of domain size and transport property in ${\mathrm{VO}}_{2}$ thin films on rutile ${\mathrm{TiO}}_{2}$ (001) substrates and identified formation mechanism of the microscaled domain. It was found that domain size decreased with increasing film thickness and the domain boundary consisted of cracks and dislocations, clarified by high-resolution transmission electron microscopy. The detailed images showed, the tensile-strained ${\mathrm{VO}}_{2}$ lattices received by ${\mathrm{TiO}}_{2}$ (001) were partially relaxed around the cracks and dislocations. The relaxed lattice is likely to return the original metal-insulator transition temperature of 340 K, whereas the tensile-strained lattice has the transition at 300 K in a ${\mathrm{VO}}_{2}/{\mathrm{TiO}}_{2}$ (001) system. Thus, the mixed states of strained and relaxed crystal lattice and the increase in dislocation density in thicker films cause the overly broad resistance behavior against temperature. Furthermore, the origin of the dislocations and the thickness dependence of the domain size could be explained by the energy release of shear stress generated by competition between the pinning layers at near-interface ${\mathrm{VO}}_{2}$ layers holding the tetragonal structure and the near-surface layers separated from the substrate attempting the lattice transformation to a monoclinic structure. This understanding enables us to more precisely design the size and configuration of these domains and their transport properties.
Yellow Rail (Coturnicops noveboracensis) Occupancy in the Context of Fire in Mississippi and Alabama, USA (2017)

The Yellow Rail (Coturnicops noveboracensis) is a migratory bird with many aspects of its ecology poorly understood. The objective of this study was to examine effects of fire, vegetation structure, and landscape variables on site occupancy and detection probabilities for Yellow Rails overwintering in coastal pine savannas of Mississippi and Alabama. Between December and April, 2012–2013, dragline surveys for Yellow Rail were conducted at three conservation areas: two in Jackson County, Mississippi, and one in Mobile County, Alabama, USA. Site occupancy for Yellow Rail was 0.81 ± 0.06 (SD) with detection probabilities of 0.79 ± 0.09 (SD). Yellow Rail occupancy related negatively with time since fire, indicating fire provides conditions attractive to Yellow Rail overwintering throughout the study area. Yellow Rail use of wetland and fire-maintained habitats within coastal Mississippi during winter, coupled with continued loss of open grasslands and inadequate management of fire-dependent pine savanna habitats throughout the southeastern USA highlights the continued need to prioritize the conservation and effective management of herbaceous-dominated ecosystems.
Direct functionalization of silicon via the self-assembly of alcohols (1995)

The reaction of fluoride-etched silicon surfaces with a range of alcohols yields self-assembled films which involve direct bonding to silicon in contrast with the usual oxide-based methods. Contact-angle measurements and electrochemistry have been used to confirm the adsorption of alcohols on fluoride-etched silicon (111) wafers. This method provides a convenient route to the design of molecular-based structures on silicon.
EFFECTS OF MANUFACTURING CONDITIONS ON HYDRATION REACTIVITY OF SYNTHESIZED C<sub>2</sub>S SOLID SOLUTION (2014)

ポルトランドセメントの高ビーライト化により、クリンカー製造エネルギーの低減が期待されるが、同時に初期強度の低下も懸念される。この対処には、ビーライトの初期水和活性の改善が必要であるが、これまでビーライトの製造条件と水和活性の詳細な関係解析は行われていない。本研究では、C2S固溶体を様々な条件で合成し、高ビーライトセメント中での水和活性を評価することを目的とした。その結果、C2S固溶体の水和活性は、結晶相組成および化学組成の両者に強く影響され、Baの添加により大きく改善することが示された。
Institutional Linkages in Development Projects with Special Reference to Marine Fisheries (2019)

This chapter is concerned with some of the special macro aspects of development process as they apply to marine fisheries, particularly institutional elements and linkages at the macro level. It may well be that a concern with marine fisheries is somewhat out of the mainstream of overall economic development. Although fisheries management is usually a function of a national government, there are strong local or regional interests to be considered. The need for involvement with other national governments, international organizations or regional commissions stems from the nature of the resource and the fact that fish swim freely across national boundaries. The role of donor governments, operating bilaterally, in providing assistance to Less Developed Countries requires some comment with respect to fisheries. A central problem in any regional management system is that each national government must surrender some of its authority, an action that most states are loathe to accept.
Long-Term Follow-Up of Trauma Patients with a Vena Caval Filter (2000)

Nanotechnology as a tool to overcome the bariatric surgery malabsorption (2020)

Obesity is a metabolic disease that affects all ages; it is considered life-threatening condition as it leads to fatal complications such as; cardiovascular diseases and diabetes. The therapeutic options include; life-style modifications, pharmacotherapy intervention, and surgical intervention. Bariatric surgery (BS) is considered as the most effective option among the others for its rapid weight loss, maintaining the lost mass, and improving the quality of life of the patients. Nevertheless, BS leads to severe changes in the bioavailability of medications, especially for chronic diseases, which may reach to limit where the patient's life endangers. Recently, pharmaceutical formulations had developed several methods to improve the drug bioavailability of drugs though the implying of nanotechnology. Nonotechnology is responsible for reducing the size of the drugs to the nano range (<1000 nm), which increase the drug surface area, dissolution, absorption, and, most importantly, the bioavailability of these drugs. It is believed that BS malabsorption and drugs bioavailability problems can be solved using nanotechnology for its advantages in overcoming BS complications.
Unprecedented stacking of MV2+ dications and MV˙+ radical cations in the mixed-valence viologen salt (MV)2(BF4)3 (MV = methylviologen) (2013)

Using a slow liquid-gas diffusion method, the mixed-valence viologen salt (MV)2(BF4)3 (1) and the radical cation salt (MV)(BF4) (2) are crystallized. Both structures contain regular stacks of MV˙(+) radical cations (2) or alternating MV˙(+) and MV(2+) entities (1). A short intrastack intermolecular separation (3.23 Å) unprecedently reveals strong interactions between MV(2+) and MV˙(+) in 1.
Preferential Identification of Agonistic OX40 Antibodies by Using Cell Lysate to Pan Natively Paired, Humanized Mouse-Derived Yeast Surface Display Libraries (2019)

To discover therapeutically relevant antibody candidates, many groups use mouse immunization followed by hybridoma generation or B cell screening. One modern approach is to screen B cells by generating natively paired single chain variable fragment (scFv) display libraries in yeast. Such methods typically rely on soluble antigens for scFv library screening. However, many therapeutically relevant cell-surface targets are difficult to express in a soluble protein format, complicating discovery. In this study, we developed methods to screen humanized mouse-derived yeast scFv libraries using recombinant OX40 protein in cell lysate. We used deep sequencing to compare screening with cell lysate to screening with soluble OX40 protein, in the context of mouse immunizations using either soluble OX40 or OX40-expressing cells and OX40-encoding DNA vector. We found that all tested methods produce a unique diversity of scFv binders. However, when we reformatted forty-one of these scFv as full-length monoclonal antibodies (mAbs), we observed that mAbs identified using soluble antigen immunization with cell lysate sorting always bound cell surface OX40, whereas other methods had significant false positive rates. Antibodies identified using soluble antigen immunization and cell lysate sorting were also significantly more likely to activate OX40 in a cellular assay. Our data suggest that sorting with OX40 protein in cell lysate is more likely than other methods to retain the epitopes required for antibody-mediated OX40 agonism.
The A* speech recognition system on parallel architectures (2012)

The speed of modern processors has remained constant over the last few years but the integration capacity continues to follow Moore's law and thus, to be scalable, applications must be parallelized. In addition to the main CPU, almost every computer is equipped with a Graphics Processors Unit (GPU) which is in essence a specialized parallel processor. This paper explore how performance of speech recognition systems can be enhanced by using the A* algorithm which allows better parallelization over the Viterbi algorithm and a GPU for the acoustic computations in large vocabulary applications. First experiments with a “unigram approximation” heuristic resulted in approximatively 8.7 times less states being explored compared to our classical Viterbi decoder. The multi-thread implementation of the A* decoder combined with GPU for acoustic computation led to a speed-up factor of 5.2 over its sequential counterpart and an improvement of 5% absolute of the accuracy over the sequential Viterbi search at real-time.
The effect of hypophysectomy on inhibin production by adult rat ovaries: Changes in ovarian inhibin gene expression and serum inhibin (1988)

We have investigated the effect of hypophysectomy on adult rat ovarian inhibin alpha- and beta A-subunit mRNA, serum inhibin, and circulating gonadotrophin levels. Immediate declines in ovarian inhibin gene expression and serum inhibin were observed following hypophysectomy, with a nadir on day 4. However, inhibin synthesis determined by these parameters was still apparent at 16 days post-hypophysectomy. Gonadotropin levels were suppressed following hypophysectomy and the fall in inhibin production was highly correlated with disappearance of FSH from the circulation. This study demonstrates that removal of pituitary gonadotropin stimulation results in diminished ovarian inhibin synthesis and provides further evidence indicating that FSH stimulates granulosa cell inhibin synthesis by enhancing inhibin gene transcription.
The Inclusion of Personality Trait Based Adaptive Interfaces into Computer Based Learning and Training Environments (1995)

Over the last few years wider access students have been recruited onto manufacturing engineering degrees at the University of Salford. These students have a large variation in learning styles which are related to personality, intelligence and aptitude. In order for Computer Aided Learning material (CAL) to be effective it was realised that these attributes had to be taken into account when developing new material. The paper initially looks at the principles and features of adaptive interfaces before identifying work at the university aimed at introducing adaptive learning material with robot programming as the subject domain.
Fuel Cell Ageing Prediction and Remaining Useful Life Forecasting (2022)

Fuel cell (FC) lifetime prediction is becoming an integral part of any energy management strategy (EMS) in electrified vehicles since it is one of the key barriers in the commercialization of FCs. Remaining useful life (RuL) estimation is one of the most effective predictive maintenance tools used to develop EMSs. Prognostic health management (PHM) techniques can track the degradation of a FC and predict its RuL. Hence, in this paper, a data-based PHM method based on Long Short-Term Memory Network (LSTM) is proposed to predict the RuL of FC. This manuscript presents a benchmark to compare the prediction of the FC voltage degradation with other works that have used the same dataset. The results indicate an accuracy of 88.13% with RMSE of 0.0079, and RuL is forecasted for 135 hours of operation with an accuracy of 92.5%. Furthermore, LSTM is used to predict ageing trend of FC by considering a different current profile that the network has been trained with. This generalization has an accuracy of 79.99%. with an RMSE of 0.0351.

Linear and nonlinear characterization of low-stress high-confinement silicon-rich nitride waveguides (2015)

In this paper we introduce a low-stress silicon enriched nitride platform that has potential for nonlinear and highly integrated optics. The manufacturing process of this platform is CMOS compatible and the increased silicon content allows tensile stress reduction and crack free layer growth of 700 nm. Additional benefits of the silicon enriched nitride is a measured nonlinear Kerr coefficient n(2) of 1.4·10(-18) m(2)/W (5 times higher than stoichiometric silicon nitride) and a refractive index of 2.1 at 1550 nm that enables high optical field confinement allowing high intensity nonlinear optics and light guidance even with small bending radii. We analyze the waveguide loss (∼1 dB/cm) in a spectrally resolved fashion and include scattering loss simulations based on waveguide surface roughness measurements. Detailed simulations show the possibility for fine dispersion and nonlinear engineering. In nonlinear experiments we present continuous-wave wavelength conversion and demonstrate that the material does not show nonlinear absorption effects. Finally, we demonstrate microfabrication of resonators with high Q-factors (∼10(5)).
Mercaptoacyl aminoacid inhibitors of atriopeptidase. 1. Structure-activity relationship studies of methionine and S-alkylcysteine derivatives (1994)

A broad series of N-(3-mercaptoacyl) amino acid derivatives was evaluated for their ability to inhibit atriopeptidase (neutral endopeptidase, EC 3.4.24.11) in vitro and in vivo. Structural parameters studied were (i) the substituent on the 2-position of the 3-mercaptopropionyl moiety, (ii) the amino acid component, (iii) the S-terminal derivative, and (iv) the C-terminal derivative. Optimum activity was observed for derivatives of methionine and S-alkylcysteines. N-[3-Mercapto-2(S)-[(2-methylphenyl)methyl]-1-oxopropyl]-L-methionine was identified as a highly effective inhibitor of atriopeptidase meriting evaluation as a potential cardiovascular therapeutic agent.

Focusing Microwaves in the Fresnel Zone With a Cavity-Backed Holographic Metasurface (2018)

We present the design and experimental demonstration of a cavity-backed, holographic metasurface capable of focusing microwaves in the Fresnel zone. The circular cavity consists of two stacked plates: microwaves are injected into the bottom plate via a coaxial connector, which forms the feed layer, and are coupled to the top holographic metasurface layer via an annular ring on the periphery of the cavity. This coupling results in an inward traveling cylindrical wave in the top layer, which serves as the reference wave for the hologram. A sparse array of slots, patterned into the upper plate, constitutes the hologram that produces the focal spot. To mitigate high sidelobe levels and improve performance, a tapered design, facilitated by varying the slot size, is also introduced. The proposed designs-which have a 10-cm diameter, operate at 20 GHz, and form a focal spot at a distance of 10 cm-are validated using full-wave simulations as well as measurements of fabricated samples. The proposed focusing metasurface may find application as a compact source for Fresnel zone wireless power transfer and remote sensing schemes.
Automated Demand-driven Resource Scaling in Relational Database-as-a-Service (2016)

Relational Database-as-a-Service (DaaS) platforms today support the abstraction of a resource container that guarantees a fixed amount of resources. Tenants are responsible for selecting a container size suitable for their workloads, which they can change to leverage the cloud's elasticity. However, automating this task is daunting for most tenants since estimating resource demands for arbitrary SQL workloads in an RDBMS is complex and challenging. In addition, workloads and resource requirements can vary significantly within minutes to hours, and container sizes vary by orders of magnitude both in the amount of resources as well as monetary cost. We present a solution to enable a DaaS to auto-scale container sizes on behalf of its tenants. Approaches to auto-scale stateless services, such as web servers, that rely on historical resource utilization as the primary signal, often perform poorly for stateful database servers which are significantly more complex. Our solution derives a set of robust signals from database engine telemetry and combines them to significantly improve accuracy of demand estimation for database workloads resulting in more accurate scaling decisions. Our solution raises the abstraction by allowing tenants to reason about monetary budget and query latency rather than resources. We prototyped our approach in Microsoft Azure SQL Database and ran extensive experiments using workloads with realistic time-varying resource demand patterns obtained from production traces. Compared to an approach that uses only resource utilization to estimate demand, our approach results in 1.5x to 3x lower monetary costs while achieving comparable query latencies.
Resonant inelastic x-ray scattering study of spin-wave excitations in the cuprate parent compound Ca2CuO2Cl2 (2017)

By means of resonant inelastic x-ray scattering at the Cu ${L}_{3}$ edge, we measured the spin-wave dispersion along $\ensuremath{\langle}100\ensuremath{\rangle}$ and $\ensuremath{\langle}110\ensuremath{\rangle}$ in the undoped cuprate ${\mathrm{Ca}}_{2}{\mathrm{CuO}}_{2}{\mathrm{Cl}}_{2}$. The data yield a reliable estimate of the superexchange parameter $J=135\ifmmode\pm\else\textpm\fi{}4$ meV using a classical spin-1/2 two-dimensional Heisenberg model with nearest-neighbor interactions and including quantum fluctuations. Including further exchange interactions increases the estimate to $J=141$ meV. The 40 meV dispersion between the magnetic Brillouin zone boundary points (1/2, 0) and (1/4, 1/4) indicates that next-nearest-neighbor interactions in this compound are intermediate between the values found in ${\mathrm{La}}_{2}{\mathrm{CuO}}_{4}$ and ${\mathrm{Sr}}_{2}{\mathrm{CuO}}_{2}{\mathrm{Cl}}_{2}$. Due to the low-$Z$ elements composing ${\mathrm{Ca}}_{2}{\mathrm{CuO}}_{2}{\mathrm{Cl}}_{2}$, the present results may enable a reliable comparison with the predictions of quantum many-body calculations, which would improve our understanding of the role of magnetic excitations and of electronic correlations in cuprates.
Science and Technology Text Mining: Management Decision Aids (2003)

Abstract : This report addresses issues of quality in the context of management decision aids. It proposes rules for high quality management support procedures using these aids, and presents criteria for more effective implementation of these decision aids into the strategic management of science and technology. Two illustrative examples of quality in the context of management decision aids are presented. The first addresses quality in the context of science and technology roadmaps, and the second addresses quality in the context of information retrieval for science and technology text mining. Finally, the report discusses the major barriers to implementation and integration of these decision aids into the strategic science and technology management process: * Techniques treated as add-ons * Techniques treated independently * Mismatch between performers and users.
Early Beneficial Effects of Bone Marrow-Derived Mesenchymal Stem Cells Overexpressing Akt on Cardiac Metabolism After Myocardial Infarction (2009)

Administration of mesenchymal stem cells (MSCs) is an effective therapy to repair cardiac damage after myocardial infarction (MI) in experimental models. However, the mechanisms of action still need to be elucidated. Our group has recently suggested that MSCs mediate their therapeutic effects primarily via paracrine cytoprotective action. Furthermore, we have shown that MSCs overexpressing Akt1 (Akt-MSCs) exert even greater cytoprotection than unmodified MSCs. So far, little has been reported on the metabolic characteristics of infarcted hearts treated with stem cells. Here, we hypothesize that Akt-MSC administration may influence the metabolic processes involved in cardiac adaptation and repair after MI. MI was performed in rats randomized in four groups: sham group and animals treated with control MSCs, Akt-MSCs, or phosphate-buffered saline (PBS). High energy metabolism and basal 2-deoxy-glucose (2-DG) uptake were evaluated on isolated hearts using phosphorus-31 nuclear magnetic resonance spectroscopy at 72 hours and 2 weeks after MI. Treatment with Akt-MSCs spared phosphocreatine stores and significantly limited the increase in 2-DG uptake in the residual intact myocardium compared with the PBS- or the MSC-treated animals. Furthermore, Akt-MSC-treated hearts had normal pH, whereas low pH was measured in the PBS and MSC groups. Correlative analysis indicated that functional recovery after MI was inversely related to the rate of 2-DG uptake. We conclude that administration of MSCs overexpressing Akt at the time of infarction results in preservation of normal metabolism and pH in the surviving myocardium.
