Direct Measurement of the Nuclear and Solvent Contributions to the Electron-Transfer Dynamics in Mixed Valence Metal Dimers (1994)

The electron-transfer in mixed valence metal dimers is investigated with sufficient time resolution (20 fs) to unravel coherent and incoherent electronic, vibrational, and solvent motion for the first time. These compounds represent an ideal class of reactions on which to develop condensed-phase electron-transfer (ET) theories. [1, 2] An example in these reactions is the ruthenium-ruthenium mixed valence compound (RuRu): Photoexcitation initiates the migration of an electron between metal centers with internal conversion from the excited state to the ground state corresponding to the back-electron transfer. We have constructed a 20-fs absorption spectrometer based on a Ti:Sapphire oscillator which is capable of measuring the ultrafast reaction dynamics.[3]
Development Status of DFMC-SBAS using QZSS PTD (Positioning Technology Development) Subsystem (2019)

Quasi-Zenith Satellite System (QZSS) is the Japanese satellite positioning system composed of satellites in quasi-zenith orbits, satellites in geostationary orbits, and ground-based systems. One of the services in QZSS is Positioning Technology Verification Service (hereinafter PTV). This paper reports on the verification test of next generation high accuracy positioning technology using PTV and the development status of dual frequency positioning augmentation technology using the QZSS positioning technology development subsystem (hereinafter PTD subsystem).
Alternative Minimum Tax, Personal: From The Encyclopedia of Taxation and Tax Policy (1999)

The personal alternative minimum tax (AMT) requires individuals to calculate their income tax a second way, different from the regular income tax. Separate tax rates and definitions of taxable income apply in each of these tax systems. This article explores the history and justification for the AMT, as well as the treatment of tax preferences in the AMT.
A 4-ns BiCMOS translation-lookaside buffer (1990)

A 64-entry fully associative TLB (translation-lookaside buffer) with a pin-to-pin translation delay of 3.6 ns is described. This translation speed is achieved by using BiCMOS content-addressable memory (CAM) and SRAM arrays wherein small signal swings are maintained throughout the critical translation path. A BiCMOS CAM cell that uses a single bipolar translator to drive the match line is introduced. The TLB has been integrated as a stand-alone chip in an 0.8- mu m BiCMOS technology. The circuit operates from a 5.2-V supply with ECL-compatible input and output levels. The power dissipation (excluding the power dissipated in the physical address output buffers) is less than 600 mW.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Node.js scalability investigation in the cloud (2018)

Node.js has gained popularity in cloud development due to its asynchronous, non-blocking and event-driven nature. However, scalability issues can limit the number of concurrent requests while achieving an acceptable level of performance. To the best of our knowledge, no cloud-based benchmarks or metrics focusing on Node.js scalability exist. This paper presents the design and implementation of Ibenchjs, a scalability-oriented benchmarking framework, and a set of sample test applications. We deploy Ibenchjs in a local and isolated cloud to collect and report scalability-related measurements and issues of Node.js as well as performance bottlenecks. Our findings include: 1) the scaling performance of the tested Node.js test applications was sub-linear; 2) no improvements were measured when more CPUs were added without modifying the number of Node.js instances; and 3) leveraging cloud scaling solutions significantly outperformed Node.js-module-based scaling.
Quasi-bound states in the continuum enhanced wavelength conversion in lossy chalcogenide metasurfaces (Conference Presentation) (2022)

We experimentally demonstrate near-infrared to ultraviolet (UV) wavelength conversion in an As2S3-based metasurface that is strongly enhanced by the excitation of a quasi-bound states in the continuum resonance near 1064 nm. We report the all-optical, ultrafast tunability of the QBIC resonance and the third harmonic induced by Kerr effects. These results give rise to a range of novel applications for UV sensors and lasers.
Sidescan sonar image processing techniques (1993)

A four-step processing sequence is described to produce image mosaics from the various segments of a sidescanned acoustic imaging survey of a given seafloor area. Starting with data consisting for each ping of acoustic backscatter levels versus horizontal range across-track, median prefiltering is used first to reduce the influence of outliers on subsequent linear processes. Artifacts that are clearly unrelated to the backscattering properties of the seafloor are then isolated on a ping by ping basis through a spectral analysis that relies on a decomposition using Chebyshev polynomials to filter the low spatial frequency components of the image. Contrast enhancement is then achieved through an original implementation of the classical gray level histogram equalization technique by balancing local versus global histogram contributions. Pixels are mapped on a geographic grid taking due account of the geometry of the measurement and of the spacing between pings to minimize along-track smearing of features. Examples of results obtained with these processing techniques are given for SeaMARC II data recorded during a complete survey of Fieberling Guyot (32 degrees .5 N, 128 degrees W).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Locally linearized longitudinal and lateral-directional aerodynamic stability and control derivaties for the X-29A aircraft (1984)

The locally linearized longitudinal and lateral-directional aerodynamic stability and control derivatives for the X-29A aircraft were calculated for altitudes ranging from sea level to 50,000 ft, Mach numbers from 0.2 to 1.5, and angles of attack from -5 deg to 25 deg. Several other parameters were also calculated, including aerodynamic force and moment coefficients, control face position, normal acceleration, static margin, and reference angle of attack.
Vaccinia virus GLV‐1h153 in combination with <sup>131</sup> I shows increased efficiency in treating triple‐negative breast cancer (2013)

We investigated the therapeutic efficacy of a replication-competent oncolytic vaccinia virus, GLV-1h153, carrying human sodium iodide symporter (hNIS), in combination with radioiodine in an orthotopic triple-negative breast cancer (TNBC) murine model. In vitro viral infection was confirmed by immunoblotting and radioiodine uptake assays. Orthotopic xenografts (MDA-MB-231 cells) received intratumoral injection of GLV-1h153 or PBS. One week after viral injection, xenografts were randomized into 4 treatment groups: GLV-1h153 alone, GLV-1h153 and (131)I (∼ 5 mCi), (131)I alone, or PBS, and followed for tumor growth. Kruskal-Wallis and Wilcoxon tests were performed for statistical analysis. Radiouptake assay showed a 178-fold increase of radioiodine uptake in hNIS-expressing infected cells compared with PBS control. Systemic (131)I-iodide in combination with GLV-1h153 resulted in a 6-fold increase in tumor regression (24 compared to 146 mm(3) for the virus-only treatment group; P<0.05; d 40). We demonstrated that a novel vaccinia virus, GLV-1h153, expresses hNIS, increases the expression of the symporter in TNBC cells, and serves both as a gene marker for noninvasive imaging of virus and as a vehicle for targeted radionuclide therapy with (131)I.

Real-time bag of words, approximately (2009)

We start from the state-of-the-art Bag of Words pipeline that in the 2008 benchmarks of TRECvid and PASCAL yielded the best performance scores. We have contributed to that pipeline, which now forms the basis to compare various fast alternatives for all of its components: (i) For descriptor extraction we propose a fast algorithm to densely sample SIFT and SURF, and we compare several variants of these descriptors. (ii) For descriptor projection we compare a k-means visual vocabulary with a Random Forest. As a preprojection step we experiment with PCA on the descriptors to decrease projection time. (iii) For classification we use Support Vector Machines and compare the x2 kernel with the RBF kernel. Our results lead to a 10-fold speed increase without any loss of accuracy and to a 30-fold speed increase with 17% loss of accuracy, where the latter system does real-time classification at 26 images per second.
Arylation of Pyridine with 9,10-Dioxoanthracenyl-1(2)-diazonium Hydrosulfates (2018)

9,10-Dioxoanthracenyl-1(2)-diazonium hydrosulfates reacted with pyridine under both the modified Gomberg–Bachmann reaction conditions and in the presence of catalytic amounts of CuCl2 to form a mixture of isomeric 2-, 3-, and 4-pyridylanthraquinones, of which 2-pyridyl derivatives were isolated in an analytically pure form.
Modulatory Effect of Polyphenolic Compounds from the Mangrove tree &lt;em&gt;Rhizophora mangle &lt;/em&gt;L. Improving Non-Alcoholic Fatty Liver Disease and Insulin Resistance in High-Fat Diet Obese Mice (2018)

Rhizophora mangle L. is a well-known medicinal plant found in mangroves worldwide used to treatment diabetes. This study evaluated the chemical composition of the acetonic extract from Rhizophora mangle barks (AERM), by HPLC-PDA and FIA-ESI-IT-MS/MS and the effects on high-fat diet induced obesity in mice and its mechanism of action by gene expression of inflammatory markers (Pparg, Ppara, Srebf1, Cd36, Tnf, Ccl2, Lep, Il10, Il6, Fasn, 18s). High-fat diet fed mice during 12 weeks was used as model of obesity and associated alterations. The results were very satisfactory, the extract, rich in polyphenolic compounds, flavonoids and phenolic acids, displayed intense antioxidant activity in vitro (608 &amp;micro;mol Trolox/g), and showed excellent activity against non-alcoholic fatty liver disease (NAFLD) and reverse insulin resistance in a model of diet-induced obesity. We can registered a modulatory effect of AERM in liver PPAR-&amp;gamma; mRNA expression associated to an important inhibition of CD36 mRNA expression suggesting that AERM induces the down regulation of CD36 mRNA via PPAR-gamma inhibition. These results support the traditional knowledge about the use of R. mangle for the treatment of type 2 diabetes and reveal the potential of AERM for the treatment of NAFLD and management of obesity and comorbidities.
Multi-Rate Compression for Downlink CSI Based on Transfer Learning in FDD Massive MIMO Systems (2021)

Accurate downlink channel state information (CSI) is one of the essential requirements for harnessing the potential advantages of frequency-division duplexing (FDD) massive multi-input multi-output (MIMO) systems. The current state-of-art in this vibrant research area include the use of deep learning to compress and feedback downlink CSI at the user equipments (UEs). These approaches focus mainly on achieving CSI feedback with high reconstruction performance and low complexity, but at the expense of inflexible compression rate (CR). High training overheads and limited storage capacity requirements are some of the challenges associated with the design of dynamic CR, which instantaneously adapt to propagation environment. This paper applies transfer learning (TL) to develop a multi-rate CSI compression and recovery neural network (TL-MRNet) with reduced training overheads. Simulation results are presented to validate the superiority of the proposed TL-MRNet over traditional methods in terms of normalized mean square error and cosine similarity.

Single-element handset antenna design for modern smartphones: An industrial approach (2017)

In order to fulfil strict design requirements for antennas in real products, a new approach to handset antenna design is studied. In the beginning, the shape of the antenna element is fixed and the actual design is done by adjusting the position of the feeding pins and by using passive circuit elements. The designed single-element antenna covers LTE frequency bands 698-960 MHz, 1710-2690 MHz, and the high band around 3.5 GHz without tunable circuit elements.
Blood—Brain Barrier Permeability Precedes Senile Plaque Formation in an Alzheimer Disease Model (2003)

A breakdown of BBB was evident in young 4- to 10-month-old Tg2576 mice. Compromised barrier function could explain the mechanisms of Abeta entry into the brain observed in experimental Alzheimer disease vaccination models. Such structural changes to the BBB caused by elevated Abeta could play a central role in Alzheimer disease development and might define an early point of intervention for designing effective therapy against the disease.

Recent measurements of neutron capture cross sections in the fission product mass region. [Tables 3 to 200 keV, resonance, parameters, strength functions, doorway state density, resonance parameters] (1978)

The radiative capture cross sections for the separated isotopes of Sr, Y, Zr, Mo, Pd, Cd, Ba, La, Ce, Pr and Nd in the energy range 3 to 200 keV were measured with high energy resolution at the 40 m station of the Oak Ridge Electron Linear Accelerator. Maxwellian averaged 30 keV cross sections and average resonance parameters derived from the analysis are tabulated. A strong dependence of the average radiative widths on neutron binding energy is noted. This leads to a pronounced even-odd disparity. Neutron strength functions reduce with decreasing binding energy along an isotopic chain owing to the decreasing density of doorway states at the binding energy. 16 references.
A robust optimization strategy for intensity-based 2D/3D registration of knee implant models to single-plane fluoroscopy (2007)

During intensity-based 2D/3D registration of 3D CAD models of knee implant components to a calibrated single-plane fluoroscopy image, a similarity measure between the fluoroscopy and a rendering of the model onto the image plane is maximized w.r.t. the 3D pose parameters of the model. This work focuses on a robust strategy for finding this maximum by extending the standard Powell optimization algorithm with problem-specific knowledge. A combination of feature-based and intensity-based methods is proposed. At each iteration of the optimization process, feature information is used to compute an additional search direction along which the image-based similarity measure is maximized. Hence, the advantages of intensity-based registration (accuracy) and feature-based registration (robustness) are combined. The proposed method is compared with the standard Powell optimization strategy, using an image-based similarity measure only, on simulated fluoroscopy images. It is shown that the proposed method generally has higher accuracy, more robustness and a better convergence behavior. Although introduced for the registration of 3D CAD models of knee implant components to single-plane fluoroscopy images, the optimization strategy is easily extendible and applicable to other 2D/3D registration applications.
Bolometric Properties of Semiconducting and Metallic Single-Walled Carbon Nanotube Composite Films (2015)

Single-walled carbon nanotubes (SWNTs) have shown interesting bolometric properties, making them good candidates for the detection of infrared and terahertz radiation. However, little has been reported on the bolometric characteristics of SWNT as a function of their chirality or the possible influence of composite morphology on these properties. The separation of SWNTs based on chirality allows for almost purely semiconductive or metallic SWNTs to be studied. The current study focuses on the bolometric performance of self-assembled composite films of SWNTs. The dependence of these properties on the chirality of the SWNTs was evaluated. To this end, metallic, semiconducting, and a 1:1 mixture of metallic and semiconductive were studied. Also, a theoretical model based on the Wiedemann–Franz law is used to explain the resistance of the SWNT composite films as a function of temperature. Results show that the composite morphology has a significant impact on bolometer performance, with cracked composite films containing highly aligned SWNT arrays suspended over a silicon substrate showing superior responsivity values due to higher thermal isolation. Uncracked composite films showed superior thermal coefficient of resistance values (α = −6.5%/K), however, the responsivity was lower due to lower thermal isolation.
Psychometrics of Dominant Right Hand During the 9‐Hole Peg Test: Differences Between Peg Placement and Removal (2011)

Although healthy subjects perform the 9-Hole Peg Test more efficiently using their dominant hands, the difference in measured dexterity was observed only during the peg-placement phase. This discrepancy between the peg-placement and peg-removal efficiency suggests the need for phase discrimination in future studies.

Stator thermal time constant (2013)

The thermal model providing motor overload protection is derived from the first order differential equation for heat rise due to current in a conductor. Only the stator thermal time constant and the service factor are the required settings. The thermal model utilizes the full thermal capacity of the motor and allows current swings and cyclic overloads that would trip conventional overcurrent protection but do not actually overheat the motor. Four examples of thermal limit curves and their equations are used to discuss the varying plotting practices in use. The paper also includes a method to calculate the stator thermal time constant using two points read from the overload curve when not available from motor data.
Supraphos:  A Supramolecular Strategy To Prepare Bidentate Ligands (2004)

We report a new strategy for the preparation of chelating bidentate ligands, which involves just the mixing of two monodentate ligands functionalized with complementary binding sites. In the current example, the assembly process is based on selective metal-ligand interactions, using phosphite zinc(II) porphyrins 1-6 and the nitrogen donor ligands b-i. From only 16 monodentate ligands, a library of 60 palladium catalysts based on 48 bidentate ligand assemblies has been prepared. The relatively small catalyst library gave a large variety in the selectivity of the alkylation of rac-1,3-diphenyl-2-propenyl acetate. Importantly, small variations in the building blocks lead to large differences in the enantioselectivity imposed by the catalyst (up to 97% ee).
Angiotensin II and neurohumoral control of the renal medullary circulation (2009)

1. Angiotensin (Ang) II has multiple actions in the renal medullary circulation. It can induce vasodilatation and blunt the response of medullary blood flow (MBF) to renal nerve activation through AT(1) receptor-mediated release of nitric oxide (NO) and/or vasodilator prostaglandins. These actions require high intravascular and/or intratubular AngII concentrations, so are not apparent under physiological conditions. 2. Nevertheless, these mechanisms blunt the responsiveness of MBF to AT(1) receptor-mediated vasoconstriction. When these protective mechanisms fail, as when oxidative stress reduces NO bioavailability in the medullary circulation, AngII reduces MBF. If sustained, reduced MBF leads to the development of hypertension. 3. Chronic activation of the renin-angiotensin system (RAS) induces oxidative stress in the kidney. Therefore, MBF may be reduced in models of hypertension associated with RAS activation both because AngII levels per se are increased and because of increased responsiveness of MBF to AngII-induced vasoconstriction. 4. Endogenous AngII enhances the responsiveness of MBF to renal nerve stimulation, whereas NO blunts it. Chronic RAS activation and/or oxidative stress should therefore be expected to enhance MBF responses to renal nerve stimulation. Consistent with this, reductions in MBF induced by renal nerve stimulation are enhanced in rabbits with AngII-induced hypertension, renovascular hypertension or after 9 weeks of fat feeding. 5. We conclude that the ability of endogenous AngII to reduce MBF and enhance the response of MBF to activation of the renal nerves could contribute to the development of hypertension under conditions of RAS activation, especially if accompanied by increased renal sympathetic nerve activity.
