Bragg-Williams model of Fe-Co order-disorder phase transformations in a strong magnetic field (2006)

A modified Bragg-Williams statistical model with nearest-neighbor magnetic exchange and chemical interactions and an additional Zeeman energy term has been used to predict an increase in the critical ordering temperature (Torder) of Fe-Co alloys in the presence of a large magnetic field (ΔTorder∼20K near equiatomic composition for H=100T). The magnitude of the predicted ΔTorder increases with increasing field and is only predicted to be significant (ΔTorder≳2−3K near equiatomic) for H≳10T. The predicted shift in the ordering temperature is due to the higher average exchange interaction per atom in the ordered phase resulting in a larger theoretical Curie temperature as compared to the disordered phase. The dependence of the average magnetic moment of Fe on the degree of order was neglected in this work, however it is expected to contribute to an additional shift in Torder. Theoretical magnetization versus temperature curves are also presented for equiatomic FeCo subject to uniform applied magnetic fields.
Effects of KOB, a polyherbal medicine for allergic rhinitis and its main herb, Astragali Radix on allergic responses in OVA-induced Allergic rhinitis mice (2012)

Objectives : In this study, we investigated the effect of KOB, a polyherbal medicine for allergic rhinitis and its main herb, Astragali Radix on allergic responses in ovalbumin (OVA)-induced Allergic rhinitis(AR) mice. Methods : Sprague Dawley (SD)-rats were orally administrated with KOB (500 mg/kg), Astragali Radix water extract (ARW, 100 mg/kg) or anti-histamine drug, dosodium cromoglycate (50 mg/kg) as a reference drug, and then intraperitoneally injected with compound 48/80 (8 mg/kg). Rats were measured the mortality and serum levels of histamine. BALB/c mice were orally administrated with KOB (500 mg/kg), ARW (100 mg/kg) or anti-histamine drug, Ketotifen (10 mg/kg) as a reference drug, followed by sensitization and challenge of OVA. Mice were measured the serum levels of histamine and IgE, and observed histopathological changes of nasa mucosa H&E staining. Results : KOB and ARW significantly decreased the mortality and the serum levels of histamine in compound 48/80-induced anaphylatic rats. KOB and ARW also decreased the serum levels of histamine and IgE in OVA-induced AR mice, and inhibited histopathological changes of nasal mucosa with inflammation and the eosinophils infilteration. Conclusions : These data suggest that KOB has a strong anti-allergic effect through the inhibitory property of Astragali Radix, the main component of KOB against allergic responses in allergic rhinitis.
Effect of somatic mutation on DNA binding properties of anti‐DNA autoantibodies (2007)

Autoantibodies that bind DNA are a hallmark of systemic lupus erythematosus. A subset of autoantibody*DNA complexes localize to kidney tissue and lead to damage and even death. 11F8, 9F11, and 15B10 are clonally related anti-DNA autoantibodies isolated from an autoimmune mouse. 11F8 binds ssDNA in a sequence-specific manner and causes tissue damage, while 9F11 and 15B10 bind ssDNA non-specifically and are benign. Among these antibodies, DNA binding properties are mediated by five amino acid differences in primary sequence. Thermodynamic and kinetic parameters associated with recognition of structurally different DNA sequences were determined for each antibody to provide insight toward recognition strategies, and to explore a link between binding properties and disease pathogenesis. A model of 11F8 bound to its high affinity consensus sequence provides a foundation for understanding the differences in thermodynamic and kinetic parameters between the three mAbs. Our data suggest that 11F8 utilizes the proposed ssDNA recognition motif including (Y32)V(L), a hydrogen bonding residue at (91)V(L), and an aromatic residue at the tip of the third heavy chain complementarity determining region. Interestingly, a somatic mutation to arginine at (31)V(H) in 11F8 may afford additional binding site contacts including (R31)V(H), (R96)V(H), and (R98)V(H) that could determine specificity.

Formation and Reactivity Thermodynamics of Sodium Sulfate With Gas Turbine Alloys (1968)

Based upon a thermodynamic study of the accelerated oxidation of superalloys exposed in oxidizing environments containing minor quantities of sea salt, it is concluded that (a) NaCl is necessary only to form Na2SO4, (b) Na2SO4 is formed by the reaction between NaCl and the oxides of sulfur, (SO2 and SO3) and (c) accelerated oxidation attack occurs only when Na2SO4 is present in the condensed form. Experimental verifications of the above conclusions is presented.

Peel behavior of polyurethane/Monel 400 interface under load in saline water (2022)

ABSTRACTThis study investigates the coupling effects of saline water and cable weight on the adhesive energy of polyurethane/Monel 400 interface using a dead weight peel test. Cables play a crucial role in naval structures serving as a central nervous system. The cables and their connectors are generally molded, encapsulated, or potted with polyurethanes to ensure that they are insulated and waterproof. During service, exposure of some of these cables and their connectors to the marine environment results in the premature failure of the polyurethane/metal interfaces of connectors. Three sets of experiments were carried out to better understand this phenomenon: an initial 90° fixed arm peel test to determine the strength of the interface, a hanging weight peel test in saline water at an elevated temperature to determine the effects of weight variation and saline water degradation, and a dead weight peel test at varying saline water temperatures to determine the acceleration factor. According to the findings, no peel was recorded in the peel experiments conducted in air indicating that the strength of the interface is higher than that of the peel arm. In the dead weight peel tests, increasing the masses of the hanging weights increased the peel velocity. Additionally, for low peel velocities, a linear relationship was observed between adhesive energy and peel velocity. Furthermore, a more cohesive primer failure was observed at the end of the peel process, indicating that peel velocity increased with longer exposure to saline water.KEYWORDS: PolyurethaneMonel 400interfacepeelsaline water AcknowledgementsThe authors kindly acknowledge the financial support provided by Dr Elizabeth Magliula of NUWC Division Newport, from the Naval Engineering Education Consortium (NEEC) Grant No. N00174-19-1-0005.

A compact and low-cost automatic image stabilization (AIS) system for camcorders has been developed. The new technology used in the system consists of a vibration-type gyro sensor with vibration feedback, an AIS control system using observer theory and an intentional camera motion discrimination algorithm. This is the first AIS system developed for consumer use and applied to camcorders with an image fluctuation suppression rate as high as -18 dB (1 Hz) or -38 dB (10 Hz).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Introduction to the 3GPP‐defined NTN standard: A comprehensive view on the 3GPP work on NTN (2023)

Summary With the recent publication of a set of technical specifications in 3rd Generation Partnership Project (3GPP) related to non‐terrestrial network (NTN) enhancements, a global standard for satellite systems is newly defined aiming to support any orbit, any frequency band, and any device. It opens the door for the seamless integration of satellite network component in 5G system and beyond, delivering the promise of a ubiquitous mobile system that can support new use cases. The emergence of hybrid terrestrial‐satellite systems is the result of a joint effort between stakeholders of both mobile and satellite industries and is paving the way to new business opportunities. This paper attempts to provide a comprehensive view on this 3GPP NTN standard and what are the next steps.
MicroCast: Cooperative Video Streaming using Cellular and D2D Connections (2014)

We consider a group of mobile users, within proximity of each other, who are interested in watching the same online video at roughly the same time. The common practice today is that each user downloads the video independently on her mobile device using her own cellular connection, which wastes access bandwidth and may also lead to poor video quality. We propose a novel cooperative system where each mobile device uses simultaneously two network interfaces: (i) the cellular to connect to the video server and download parts of the video and (ii) WiFi to connect locally to all other devices in the group and exchange those parts. Devices cooperate to efficiently utilize all network resources and are able to adapt to varying wireless network conditions. In the local WiFi network, we exploit overhearing, and we further combine it with network coding. The end result is savings in cellular bandwidth and improved user experience (faster download) by a factor on the order up to the group size. We follow a complete approach, from theory to practice. First, we formulate the problem using a network utility maximization (NUM) framework, decompose the problem, and provide a distributed solution. Then, based on the structure of the NUM solution, we design a modular system called MicroCast and we implement it as an Android application. We provide both simulation results of the NUM solution and experimental evaluation of MicroCast on a testbed consisting of Android phones. We demonstrate that the proposed approach brings significant performance benefits without battery penalty.

Coalescence of Single Photons Emitted by Disparate Single-Photon Sources: The Example of InAs Quantum Dots and Parametric Down-Conversion Sources (2011)

Single photons produced by fundamentally dissimilar physical processes will in general not be indistinguishable. We show how photons produced from a quantum dot and by parametric down-conversion in a nonlinear crystal can be manipulated to be indistinguishable. The measured two-photon coalescence probability is 16%, and is limited by quantum-dot decoherence. Temporal filtering to the quantum-dot coherence time and accounting for detector time response increases this to 61% while retaining 25% of the events. This technique can connect different elements in a scalable quantum network.
The causal effects of serum lipids and apolipoproteins on kidney function: multivariable and bidirectional Mendelian-randomization analyses (2021)

Our MR estimates suggest that serum lipid and apolipoprotein levels do not cause substantial changes in kidney function. A possible weak effect of higher atherogenic lipids on increased eGFR and UACR warrants further investigation. Processes leading to higher UACR may lead to more atherogenic lipid levels.

Use of Face Detection to Qualify Image Processing Algorithms (2012)

Image processing algorithms always affect the quality of the image to which they are applied. Traditionally, the effects of these algorithms are determined using broad image quality measurements such as PSNR, SSIM, VIF and MSE. These quantitative measures, however, do not provide a functional assessment of the image processing algorithms. In this paper, we propose and introduce the use of facial detection as such a functional measurement of image quality after performing image processing transformations on the image. To assess this, we downsampled images containing a combined 953 faces, then upsampled the images using five different image processing operations including interpolation and filtering with different parameters. This process resulted in the misdetection of 12-20 images (and a 14-21% increase in error rate) in comparison to the original set, illustrating the deleterious effect of downsampling and subsequent upsampling on the images.

Stability of Headspace Volatiles in a ‘Fallglo’ Tangerine Juice Matrix System at Room Temperature (2011)

Gas chromatography systems are usually equipped with autosamplers. Samples held in the autosampler tray can stay up to one day or longer at room temperature, if the tray is not equipped with a cooling mechanism. The objective of this research was to determine if holding samples at room temperature influences measurement of volatiles by using ‘Fallglo’ tangerine juice as a model. Tangerine juice mixed with saturated NaCl containing an internal standard (IS), 3-hexanone, was held in the autosampler for different periods of time at 25 °C, incubated at 40 °C, and then exposed to a solid phase microextraction (SPME) fiber to absorb volatiles at 75-min intervals prior to be analyzed by a GC-MS system. Results showed that there were significant changes caused by a 24 h or longer holding time at 25 °C in absolute peak area (APA) for 12 volatiles out of a total of 16 compounds detected, including hexanal, E-2-hexenal, s-pinene, octanal, d-limonene, linalool, nonanal, butyl-2-methylpropionate, copaene, caryophyllene, and valencene and the IS, 3-hexanone. However, there were no differences for four terpenes: α-thujene, α-pinene, α-terpinene and p-cymene. Three aldehydes (hexanal, E-2-hexenal and octanal) increased linearly at a rate of 144%, 238%, and 127% per day, respectively. The proportion agrees with a Henry’s law based model. Butyl 2-methylpropionate, the only ester detected, decreased in both absolute and relative amounts (relative to IS), indicating that esters may not be favorable compounds in competition for binding sites on the SPME fiber chosen. Terpenes and terpene alcohols increased in absolute amount but decreased in relative amount as holding time was extended. The research confirmed that extended holding time at room temperature markedly influenced the profile of volatile measurements, and the change in IS during holding period did not represent other volatile components.

Subwavelength grating reflectors in MEMS tunable Fabry-Perot infrared filters with large aperture (2014)

This paper presents a novel tunable infrared filter applying a subwavelength grating that substitutes the distributed Bragg reflectors (DBRs) in tunable Fabry-Perot (FP) filters to reduce cost and fabrication effort. It consists of uniformly arranged disc resonators which are made of 100 nm thick aluminum at a 200 nm Si3N4 membrane carrier that stands freely after fabrication. The dimensions of the subwavelength structures were optimized based on finite difference time domain (FDTD) analysis. The fabrication sequence consists of silicon MEMS technology steps like deposition and patterning of electrodes and of isolation layers, silicon etching, and wafer bonding, and it includes nano imprint lithography for forming the subwavelength structures at wafer level. The samples have an aperture of 2 mm and are mechanically tuned by electrostatic forces with tuning voltages up to 80 V. They show the typical characteristics of FP filters but with high peak transmittance within a remarkably large wavelength range (T &lt; 50% @ 2.5 μm … 6.5 μm) spanning over 5 interference orders of the optical resonator. The optical performance was measured by Fourier transform infrared spectrometer and compared to the simulation results. It shows a widely good agreement between calculation and measurement.
Association of systolic, diastolic, mean, and pulse pressure with morbidity and mortality in septic ICU patients: a nationwide observational study (2023)

Blood pressure component association with ICU mortality is the strongest for mean followed by systolic, diastolic, and weakest for pulse pressure. Critical care teams should continue to follow MAP-based resuscitation, though exploratory analysis focusing on blood pressure components in different sepsis phenotypes in critically ill ICU patients is needed.

Space qualification of a 10W single-mode PM optical amplifiers in the 1.5-µm region (2021)

MPB has developed a 10W Polarization Maintaining Optical Fiber amplifier (1550 nm) for space applications. The prototype is based on three stages of optical amplification with photodiodes at each stage, monitoring the output power. It includes the control electronics and software with feedback loops to dynamically control and monitor the amplifier. The design had to overcome many challenges to comply with the mechanical, thermal, radiation, and vacuum requirements for the LEO satellite space environment, while at the same time meeting the price targets for LEO constellations by maximizing the use of commercial off the shelf (COTS) components. The following were the main challenges: a) to effectively dissipate the heat generated (75-90 W); b) to select radiationtolerant electronics to drive the needed electrical current; c) to source and effectively implement components, such as the combiners and isolators, in the high power optical path compatible with vacuum at 10W output. The major challenge with regard to heat management was to find an optimal method to dissipate the heat from the third stage (high power) Erbium Ytterbium Doped Fiber. Commonly, this fiber is spooled on an Aluminium spool. The difference in the Constant Temperature Extension (CTE) between the fiber (low) and Aluminium (high) leads to a detachment of the fiber at low temperature with a high risk of breaking the fiber when passing from OFF to ON. At high temperatures, the Aluminium extends much more than the fiber, leading to an over tension on the fiber with a high risk of mechanical breakage. Different designs of the spool, supports inside the box, selection of materials, and process implementations were tried. An innovative, proprietary method was developed to satisfy this requirement. The unit successfully passed performance testing between -20°C and +40°C in vacuum with 10W output, with a wall plug efficiency of 11%. The lower temperature limitation was due to the specification of the high-power laser diodes. The higher temperature was limited by the local heating and risk of mechanical breaking of the third-stage COTS combiner and isolator. Vibration and mechanical shock are not foreseen to be an issue. The simulation demonstrated the prototype is complying with these requirements. Moreover, MPB has built similar instruments at lower power levels that have successfully passed these qualification tests. The components used were available as COTS products, including the radiation-tolerant electronics. All the components were qualified individually for &gt;30 krad, in vacuum, and for the temperature range -35°C to +65°C except for the highpower laser diodes which were limited to -25°C. MPBC is continuing the qualification, implementing minor design changes, in order to satisfy the complete temperature range (-35°C to +65°C).
