A SAW resonator with two-dimensional reflectors (2009)

It is known that a part of the loss of Leaky SAW resonators is due to radiation of acoustic energy in the bussbars. A lot of researchers are working on so called ldquoPhononic crystalsrdquo. A 2D grating of very strong reflectors allows these devices to fully reflect, for a given frequency band, any incoming wave. A new device, based on the superposition of a regular SAW resonator and of a 2D periodic grating of reflectors, is proposed. Several arrangements and geometries of the reflectors were studied and compared experimentally on 48 degrees rotated Y cut Lithium Tantalate. In particular, a very narrow aperture (7.5 lambda) resonator was manufactured on 48 deg. LT in the 900 MHz range. Due to its small size, this resonator has a resonance Q of only 575 when using the standard technology while a resonance Q of 1100 was obtained for the new device without degradation of the other characteristics. Due to the narrow aperture, the admittance of the standard resonator showed a very strong parasitic above the resonance frequency while this effect is drastically reduced for the new device. These results demonstrate the feasibility of the new approach.
Phenolic lipids synthesized by type III polyketide synthase confer penicillin resistance on Streptomyces griseus. VOLUME 283 (2008) PAGES 13983-13991 (2008)

On Page 13990, the mode of ring folding of the tetraketide intermediate, leading to resorcinol formation, in Fig. 5B was incorrect. The correct ring folding is C-2-C-7 aldol condensation. This error does not change the conclusions of this study. However, the order of condensation of the extender units is updated as methylmalonyl-CoA, malonyl-CoA, and malonyl-CoA. The corrected figure is shown below.

Effect of Non-Steroidal Anti-Inflammatory Drugs on Amyloid-β Formation and Macrophage Activation after Platelet Phagocytosis (2004)

Recently, we showed that platelet phagocytosis occurs in human atherosclerotic plaques and leads to foam cell formation. Platelet phagocytosis, resulting in macrophage activation and iNOS induction, was associated with the formation of amyloid-beta peptide (Abeta) via proteolytic cleavage of platelet-derived amyloid precursor protein (APP), possibly by secretases. To test the involvement of gamma-secretase in this process, we used indomethacin, ibuprofen, and sulindac sulfide, non-steroidal anti-inflammatory drugs (NSAIDs) known to alter the gamma-secretase cleaving site of APP, on their ability to inhibit macrophage activation evoked by platelet phagocytosis. J774 macrophages were incubated with human platelets or lipopolysaccharide (LPS) with or without NSAIDs. Nitrite was quantified as a measure for inducible nitric oxide synthase (iNOS) activity. Indomethacin, ibuprofen, sulindac sulfide, and meloxicam concentration-dependently reduced nitrite production by macrophages incubated with platelets, but did not alter LPS-induced iNOS activity or platelet uptake. However, acetylsalicylic acid and naproxen, two NSAIDs without effect on the gamma-secretase cleaving site of APP, did not affect nitrite production in either platelet- or LPS-stimulated macrophages. Surface-enhanced laser desorption/ionization time-of-flight mass-spectrometry demonstrated time-dependent formation of Abeta-containing peptides after platelet phagocytosis, which could be inhibited by indomethacin. In conclusion, these results point to the involvement of gamma-secretase in macrophage activation following platelet phagocytosis.
Etiology of erythema nodosum. (1995)

One hundred patients with biopsy-proven erythema nodosum were studied at Ramathibodi Hospital from 1982 to 1992 to find out the etiology of this disease. Eighty-eight were females while twelve were males, with an age range from 6 to 72 years old (mean, 31 years old). Abnormal laboratory findings in these patients included elevation of erythrocyte sedimentation rate (76.9%), increase anti-streptolysin-O titer (10.7%), abnormal chest roentgenogram (16.7%), positive tuberculin test (50%). The cause of erythema nodosum is still unknown in a large group of patients, and it was found only in twenty-eight patients (28%). Twelve patients had tuberculosis, seven had history of antibiotic administration, six probably had streptococcal infection and the other three had Behcet's disease.
Cold Thermal Energy Storage for Reliable Ship Cooling Under Thermal Cycling and Cooling Loss (2019)

We evaluated the viability of integrating a cold thermal energy storage (CTES) into an all-electric ship to mitigate the aftermath of thermal cycling and cooling loss by providing additional thermal damping. 1D dynamic CTES and counterflow heat exchanger (HX) models were developed and solved in dimensionless forms to assess the proposed cooling configuration based on the following: (1) the impact of chiller HX (evaporator) design on thermal damping without the CTES; and (2) the effects of adding a CTES next to the chiller as a complementary thermal damper (HX + CTES). Numerical results demonstrate the higher sensitivity of the damping effect to the total number of transfer units (N) than the HX mass, and the required N to achieve the same damping effect reduces nonlinearly with increasing HX mass. Furthermore, the HX + CTES outperforms the HX of the same total mass at higher N when the effect of heat transfer overcomes that of thermal inertia, and its merit becomes more evident when we compare the operation of these two configurations. This work thus reveals the potential of HX + CTES as a practical approach for improving the overall ship cooling reliability.

Proteus: An architectural synthesis tool based on the stream programming paradigm (2009)

The problem of automatically generating hardware modules from a high level representation of an application has been at the forefront of EDA research in the last few years. Such an EDA methodology would potentially enable the large pool of software engineers and algorithm IP experts without architectural and hardware expertise to design and implement platform systems, thus dramatically reducing time to market. This paper makes the argument that such a methodology requires a programming model beyond the sequential semantics of languages like C/C++. We argue in favor of the streaming programming model in which computation and data communication are explicitly separated and optimized. Our architectural synthesis tool, Proteus, processes stream programs that partition the application into a series of streaming kernels that operate on streams of data elements. Proteus produces efficient hardware accelerators that provide orders of magnitude higher throughput than a software implementation, at an area cost very close to manual HDL implementation.

Incidence of catheter-associated urinary tract infection among dogs in a small animal intensive care unit (2004)

Results suggest that placement of an indwelling urinary catheter in dogs is associated with a low risk of catheter-associated UTI during the first 3 days after catheter placement, provided that adequate precautions are taken for aseptic catheter placement and maintenance. Results of bacterial culture of urinary catheter tips should not be used to predict whether dogs developed catheter-associated UTI.
Scheduling support for transactional memory contention management (2010)

Transactional Memory (TM) is considered as one of the most promising paradigms for developing concurrent applications. TM has been shown to scale well on >multiple cores when the data access pattern behaves "well," i.e., when few conflicts are induced. In contrast, data patterns with frequent write sharing, with long transactions, or when many threads contend for a smaller number of cores, result in numerous conflicts. Until recently, TM implementations had little control of transactional threads, which remained under the supervision of the kernel's transaction-ignorant scheduler. Conflicts are thus traditionally resolved by consulting an STM-level contention manager. Consequently, the contention managers of these "conventional" TM implementations suffer from a lack of precision and often fail to ensure reasonable performance in high-contention workloads.
Prediction of Residential Building Demand Response Potential Using Data-Driven Techniques (2017)

This paper is concerned with the evaluation of the ability of data-driven predictive models to capture the demand response potential in residential buildings. A mid-floor apartment with an air to water heat pump for space heating, utilised as an archetype dwelling, is simulated using EnergyPlus. The research is focused on forecasting the electrical demand from the heating load for the coldest month of the year, considering two types of DR events, load reduction and load increase. After the generation of the synthetic database, an artificial neural network model and a support vector machine model are examined regarding their ability to predict the electrical demand from heating loads.

Facile Reduction of Dithiocarbonates Derived from Secondary Alcohols with n-Bu3SnH–Et3B and Synthesis of 2-Furanthiones and 2-Furanones by Intramolecular Addition of Alkoxythiocarbonyl Free Radicals to Acetylenic Linkages (1990)

Abstract The reduction of dithiocarbonates or thiocarbonates by n-Bu3SnH–Et3B easily gives the corresponding hydrocarbons. The intermediate alkoxythiocarbonyl radical equivalents are trapped by properly located carbon–carbon multiple bonds. The dithiocarbonates derived from either homopropargylic or homoallylic alcohols produce tetrahydrofuranones upon treatment with n-Bu3SnH–Et3B. Application of this new method to the conversion of carbonyl compounds into olefins is also described.
Fuel-Flexible Gasification-Combustion Technology for Production of Hydrogen and Sequestration-Ready Carbon Dioxide (2001)

Electricity produced from hydrogen in fuel cells can be highly efficient relative to competing technologies and has the potential to be virtually pollution free. Thus, fuel cells may become an ideal solution to this nation's energy needs if one has a satisfactory process for producing hydrogen from available energy resources such as coal, and low-cost alternative feedstocks such as biomass. GE EER is developing an innovative fuel-flexible advanced gasification-combustion (AGC) technology for production of hydrogen for fuel cells or combustion turbines, and a separate stream of sequestration-ready CO2. The AGC module can be integrated into a number of Vision- 21 power systems. It offers increased energy efficiency relative to conventional gasification and combustion systems and near-zero pollution. The R&amp;D on the AGC technology is being conducted under a Vision-21 award from the U.S. DOE NETL with co-funding from GE EER, Southern Illinois University at Carbondale (SIU-C), and the California Energy Commission (CEC). The AGC technology converts coal and air into three separate streams of pure hydrogen, sequestration-ready CO2, and high temperature/pressure oxygen-depleted air to produce electricity in a gas turbine. The three-year program integrates lab-, bench- and pilot-scale studies to demonstrate the AGC concept. Process and kinetic modeling studies as well as an economic assessment will also be performed. This paper provides an overview of the program and its objectives, and discusses first-year R&amp;D activities, including design of experimental facilities and results from initial tests and modeling studies. In particular, the paper describes the design of the bench-scale facility and initial process modeling data. In addition, a process flow diagram is shown for a complete plant incorporating the AGC module with other Vision-21 plant components to maximize hydrogen production and process efficiency.
Influence of Titanium Surface Porosity on Adhesive Strength of Coatings Containing Calcium Silicate (2020)

Titanium-based alloys are widely used in aerospace engineering. They have good mechanical and corrosion properties but, in some cases, the material itself or the coating should meet some additional requirements. For example, it may be a requirement of high reflectance to provide effective temperature control. Wollastonite is a promising component for reflective coatings because it improves both their whiteness and mechanical properties. This paper presents the results of studying the composition, the structure and the adhesive strength of wollastonite-containing silicate coatings to titanium substrate. The surface of titanium samples was pre-treated by laser cladding with TiC and etching to provide surface porosity. It has been shown that such treatment allows a significantly increase in the adhesive strength of the coating to the substrate. A decrease in the adhesive strength was observed on titanium samples with an excess of TiO<sub>2</sub> on the surface. This is caused by the formation of crystalline PbTiO<sub>3</sub> at the interface.
Effect of Composition on the Phase Structure and Magnetic Properties of Ball-Milled LaFe11.71-xMnxSi1.29H1.6 Magnetocaloric Powders (2021)

Magnetocaloric alloys are an important class of materials that enable non-vapor compression cycles. One promising candidate for magnetocaloric systems is LaFeMnSi, thanks to a combination of factors including low-cost constituents and a useful curie temperature, although control of the constituents’ phase distribution can be challenging. In this paper, the effects of composition and high energy ball milling on the particle morphology and phase stability of LaFe11.71-xMnxSi1.29H1.6 magnetocaloric powders were investigated. The powders were characterized with optical microscopy, dynamic light scattering, X-ray diffraction (XRD), and differential scanning calorimetry (DSC). It was found that the powders retained most of their original magnetocaloric phase during milling, although milling reduced the degree of crystallinity in the powder. Furthermore, some oxide phases (&lt;1 weight percent) were present in the as-received and milled powders, which indicates that no significant contamination of the powders occurred during milling. Finally, the results indicated that the Curie temperature drops as Fe content decreases (Mn content increases). In all of the powders, milling led to an increase in the Curie temperature of ~3–6 °C.
Entropic Attraction and Repulsion in Binary Colloids Probed with a Line Optical Tweezer (1999)

The long-range entropic forces that arise between two micrometer-sized colloidal spheres in a fluid of much smaller colloidal spheres were directly measured using a line-scanned optical tweezer. This new technique allowed us to measure the functional form of the potential with sub- ${k}_{B}T$ energy and $15\mathrm{nm}$ spatial resolution. At the lowest small sphere concentrations, the potential was monotonically attractive, while at higher concentrations an oscillatory potential was observed, due to the liquid structure of the small spheres. Surprisingly, the large spheres came together only rarely at the higher concentrations, suggesting a new means for stabilizing suspensions using entropy alone.

Can an Inorganic Coating Serve as Stable SEI for Aqueous Superconcentrated Electrolytes? (2021)

Developing a stable, conformal solid electrolyte interphase (SEI) for aqueous-based Li-ion batteries has been a long-awaited dream to support the development of nontoxic and eco-friendly energy storage technologies. Toward that goal, aqueous superconcentrated electrolytes were recently introduced as their unique solvation structure allows for forming a LiF-rich SEI layer at the negative electrode, imparting the stability to the interface. However, the intrinsic stability of such LiF-rich SEI was never measured, despite growing evidence of poor passivation properties and water reduction upon operation. In this work, LiF conformal layers were coated onto lithium electrodes, and their reactivity toward superconcentrated aqueous electrolytes was studied by combining solubility measurements, in situ microscopy, and gas chromatography. We demonstrate that the use of superconcentrated electrolytes drastically reduces the solubility of LiF. However, such layer is intrinsically unstable in aqueous environments, but stable in organic electrolytes, owing to the absence of self-passivation. Comparing different interfaces, we conclude that an artificial SEI made of an inorganic coating is not suitable for preventing water reactivity in aqueous systems.
Octopamine Receptors on Locust Skeletal Muscle (1988)

Octopamine is a biogenic amine that was first discovered in the posterior salivary glands of the octopus (Erspamer and Boretti, 1951). Since that time it has been shown to be a ubiquitous constituent of all nervous systems examined, all the way from nematodes and earthworms up to vertebrates, including humans (see Evans, 1980; 1985a). The functional role of octopamine in the vertebrate nervous system, however, is at present enigmatic (Harmar, 1980; Talamo, 1980; Robertson, 1981). Octopamine occurs in three different structural isomeric forms, para-, meta- and ortho-octopamines, all of which have been shown to occur naturally in vertebrates (Williams, Couch and Midgley, 1984). The occurrence of p-and m-octopamine in the sympathetic nervous system (Ibrahim, Couch, Williams, Fregley and Midgley, 1985) and brain (Danielson, Boulton and Robertson, 1977; David and Delacour, 1980) has led to the suggestion that they may function as co-transmitters or modulators of noradrenaline action.

Adaptive Discrete Rate and Power Transmission for Spectrum Sharing Systems (2012)

In this paper we develop a framework for optimizing the performance of the secondary link in terms of the average spectral efficiency assuming quantized channel state information (CSI) of the secondary and the secondary-to-primary interference channels available at the secondary transmitter. We consider the problem under the constraints of maximum average interference power levels at the primary receiver. We develop a sub-optimal computationally efficient iterative algorithm for finding the optimal CSI quantizers as well as the discrete power and rate employed at the cognitive transmitter for each quantized CSI level so as to maximize the average spectral efficiency. We show via analysis and simulations that the proposed algorithm converges for Rayleigh fading channels. Our numerical results give the number of bits required to sufficiently represent the CSI to achieve almost the maximum average spectral efficiency attained using full knowledge of the CSI.

Numerical investigation on the influence factors of the electrical properties of carbon nanotubes-filled composites (2013)

In order to predict the electrical properties of carbon nanotubes-filled composites, a three-dimensional (3D) numerical model is proposed. A random distribution of impenetrable conducting cylinders inside a cubic insulating matrix models the morphology of the considered material. The variation of the macroscopic electrical performances of the simulated structures is estimated through a suitable 3D resistance and capacitance network associated with the different percolating paths. The introduction in the model of the capacitive effects exhibited by the material, usually not considered in other simulation approaches, allows also a significant analysis in the frequency domain. The electron tunneling effect between conducting structures, determinant in the polymer nanocomposites, is also accurately taken into account to study the composite properties. The obtained results are in good agreement with theoretical predictions and experimental data suggesting that the proposed model can properly estimate different effects upon the electrical properties providing useful hints for the optimization of nanocomposites.

SNI Encryption in TLS Through Tunneling (2017)

This draft describes the general problem of encryption of the Server
Name Identification (SNI) parameter. The proposed solutions hide a
Hidden Service behind a Fronting Service, only disclosing the SNI of
the Fronting Service to external observers. The draft starts by
listing known attacks against SNI encryption, discusses the current
co-tenancy fronting solution, and then presents two potential TLS
layer solutions that might mitigate these attacks. The first solution
is based on TLS in TLS quasi tunneling, and the second solution is
based on combined tickets. These solutions only require minimal
extensions to the TLS protocol.
