LWD and Wireline Resistivity Logs: Correction for Time and Temperature Dependent Resistivity (1995)

This paper quantifies transient temperature effects on resistivity logs caused by large differences in mud and formation temperature. The differential temperature between formation and circulating borehole fluid can be large, particularly in offshore drilIing for example when several hundreds of meters of casing is exposed to the ocean and acts as a heat sink. The temperature transient gives rise to a thermal invasion profile and translates to a time-dependent monotonic radial resistivity profile, independent of whether the rock is permeable or not. The transient problem includes the heat diffusion transient with charactersitic time of a day or so depending upon the ratio K/(pC) where K (W/(moK)) is the thermal conductivity, p (kg/m3) is the density, and C (J/(kgOK) is the heat capacity of the mineral. The changes in the distribution of water saturation driven by invasion is also time dependent. A Buckley-Leverett model for multi-phase fluid· flow in porous media is used to predict time dependent water saturation Sw(p, t). The resulting radial resistivity profiles are then input into electromagnetic modeling codes to predict the transient apparent resistivity as measured by both LWD and wireline resistivity tools. Numerical results for wellbore environments within normal operating conditions show transient temperature effects alone can cause noticable LWD and wireline curve separation.

Spectrally multiplexed single-photon detection with hybrid superconducting nanophotonic circuits (2017)

The detection of individual photons by superconducting nanowire single-photon detectors is an inherently binary mechanism, revealing either their absence or presence while concealing their spectral information. For multicolor imaging techniques, such as single-photon spectroscopy, fluorescence resonance energy transfer microscopy, and fluorescence correlation spectroscopy, wavelength discrimination is essential and mandates spectral separation prior to detection. Here, we adopt an approach borrowed from quantum photonic integration to realize a compact and scalable waveguide-integrated single-photon spectrometer capable of parallel detection on multiple wavelength channels, with temporal resolution below 50 ps and dark count rates below 10 Hz at 80% of the devices' critical current. We demonstrate multidetector devices for telecommunication and visible wavelengths, and showcase their performance by imaging silicon vacancy color centers in diamond nanoclusters. The fully integrated hybrid superconducting nanophotonic circuits enable simultaneous spectroscopy and lifetime mapping for correlative imaging and provide the ingredients for quantum wavelength-division multiplexing on a chip.
Assembly of Human Frataxin Is a Mechanism for Detoxifying Redox-Active Iron (2004)

Mitochondrial function depends on a continuous supply of iron to the iron-sulfur cluster (ISC) and heme biosynthetic pathways as well as on the ability to prevent iron-catalyzed oxidative damage. The mitochondrial protein frataxin plays a key role in these processes by a novel mechanism that remains to be fully elucidated. Recombinant yeast and human frataxin are able to self-associate in large molecular assemblies that bind and store iron as a ferrihydrite mineral. Moreover, either single monomers or polymers of human frataxin have been shown to serve as donors of Fe(II) to ISC scaffold proteins, oxidatively inactivated [3Fe-4S](+) aconitase, and ferrochelatase. These results suggest that frataxin can use different molecular forms to accomplish its functions. Here, stable monomeric and assembled forms of human frataxin purified from Escherichia coli have provided a tool for testing this hypothesis at the biochemical level. We show that human frataxin can enhance the availability of Fe(II) in monomeric or assembled form. However, the monomer is unable to prevent iron-catalyzed radical reactions and the formation of insoluble ferric iron oxides. In contrast, the assembled protein has ferroxidase activity and detoxifies redox-active iron by sequestering it in a protein-protected compartment.
Decentralized control of sound radiation using iterative loop recovery (2010)

A decentralized model-based control strategy is designed to reduce low-frequency sound radiation from periodically stiffened panels. While decentralized control systems tend to be scalable, performance can be limited due to modeling error introduced by the unmodeled interaction between neighboring control units. Since bounds on modeling error are not known in advance, it is difficult to ensure the decentralized control system will be robust without making the controller overly conservative. Therefore an iterative approach is suggested, which utilizes frequency-shaped loop recovery. The approach accounts for modeling error introduced by neighboring control loops, requires no communication between subsystems, and is relatively simple. The control strategy is evaluated numerically using a model of a stiffened aluminum panel that is representative of the sidewall of an aircraft. Simulations demonstrate that the iterative approach can achieve significant reductions in radiated sound power from the stiffened panel without destabilizing neighboring control units.
Prediction of Friction Factors and Axial Descent of Convective Coefficients in Laminar Flows through Internally Finned Tubes by Way of Solving Two-Dimensional Heat Conduction Equations (2008)

This paper reports a simple numerical procedure for the prediction of the friction factors and the axial descent of the convection coefficients in the upstream region of internally finned tubes for prevalent laminar regimes. When single-phase viscous fluids are fully developed, the velocity profiles are invariant with the axial coordinate, while the temperature distributions do vary with it. Since the 2-D momentum equation corresponds to a 2-D heat conduction equation, the 2-D velocity profiles supply the product of the friction factor and the Reynolds number, fRe. By implementing the transversal method of lines (TMOL) in the sub-domain z → 0, the 3-D energy equation is transformed into an equivalent quasi 2-D heat conduction equation. The local convective coefficient asymptotes h c,Z→0 changing with the axial coordinate z → 0 come from the quasi 2-D temperature distributions. The fRe and h c,Z→0 results have been synthesized for commensureate fin configurations in the sub-domain z → 0 of the heat exchange region where the largest heat transfer activity occurs. The modeling and numerical simulation of the present heat/fluid flow problem articulates concepts learned by students in courses on fluid mechanics, heat transfer and numerical methods.
Synthesis and structure-activity relationships of a new series of cephalosporins, E1040 and related compounds. (1992)

The synthesis and in vitro antibacterial activity of a series of 7-[(Z)-2-aminoaryl-2-oxyiminoacetamido]-3-ammoniomethyl++ +-3-cephems are described. Variation of an oxyimino moiety with aminoaryl at the C-7 side chain and a quaternary ammonium moiety at the C-3 side chain were examined and structure-activity relationships were studied. E1040, the 3-(4-carbamoylquinuclidinio)methyl derivative of the 7-alpha-methoxyimino series of aminothiadiazolyl cephalosporins, exhibited excellent activity against both Gram-positive and Gram-negative bacteria, particularly against Pseudomonas aeruginosa, and possessed high stability to beta-lactamases.
[Expression of HPV16E6 gene and preparation of monoclonal antibody against the expression product]. (1994)

The recombinant plasmid PAS1-HPV16E6 containing the HPV16E6 gene was expressed in E. coli AR120 under nalidixic acid induction. A 19KD expression protein was isolated, purified and identified. Mice were immunized with the purified E6 expression protein. A murine hybridoma, RAC6, was obtained by fusing splenic cells from an immunized BABL/c mouse with mouse myeloma cell line SP2/0-Ag14 cells, followed by screening in HAT medium, cloning and recloning in methyl cellulose. The hybridoma RAC6 stably produces specific monoclonal antibody against the E6 expression protein.
Reliability of multi-site UK Biobank MRI brain phenotypes for the assessment of neuropsychiatric complications of SARS-CoV-2 infection: The COVID-CNS travelling heads study (2022)

These results give confidence that large, multi-site MRI datasets can be collected reliably at different sites across the diverse range of MRI modalities and IDPs that could be mechanistically informative in COVID brain research. We discuss limitations of the study and strategies for further harmonisation of data collected from sites using scanners supplied by different manufacturers. These acquisition and analysis protocols are now in use for MRI assessments of post-COVID patients (N = 700) as part of the ongoing COVID-CNS study.

On Compatible Condition for Morphogenetic Diversity and Recursive Production of Multicellular Organisms (2007)

The development of a multicellular organism is a dynamic process. With the increase of the cell number, starting from one or a few cells, cells are differentiated with different compositions. These differet types of cells form an ordered pattern. It is rather surprising that differentiation in cell types and formation of controlled patterns are compatible, because the former gives morphogenetic diversification whereas the latter implies recursive production of a cell ensemble, reducing individual differences. We studied this problem by taking a simple cell model with intracellular reaction dynamics of chemical concentrations, cell-cell interactions, and increase in cell numbers. We show that, by starting from an initial object consisting of both the cell type with diverse chemicals and the differentiated cell type, the recursive production of a multicellular organism with morphogenetic diversity is possible.

Sub-millimetre accurate human hand kinematics: from surface to skeleton (2018)

A highly accurate human hand kinematics model and identification are proposed. The model includes the five digits and the palm arc based on mapping function between surface landmarks and estimated joint centres of rotation. Model identification was experimentally performed using a motion tracking system. The evaluation of the marker position estimation error, which is on sub-millimetre level across all digits, underlines model quality and accuracy. Noticeably, with the development of this model, we were able to improve various modelling assumptions from literature and found a basic linear relationship between surface and skeleton rotational angles.
Prediction-correction methods for time-varying convex optimization (2015)

We consider unconstrained convex optimization problems with objective functions that vary continuously in time. We propose algorithms with a discrete time-sampling scheme to find and track the solution trajectory based on prediction and correction steps, while sampling the problem data at a constant rate of 1/h. The prediction step is derived by analyzing the iso-residual dynamics of the optimality conditions, while the correction step consists either of one or multiple gradient steps or Newton's steps, which respectively correspond to the gradient trajectory tracking (GTT) or Newton trajectory tracking (NTT) algorithms. Under suitable conditions, we establish that the asymptotic error incurred by both proposed methods behaves as O(h2), and in some cases as O(h4), which outperforms the state-of-the-art error bound of O(h) for correction-only methods in the gradient-correction step. Numerical simulations demonstrate the practical utility of the proposed methods.

Generation of give-way behavior of pedestrian model with probabilistic intention for mobile robot navigation (2014)

In daily life, there are many bottlenecks such as narrow passages, gaps between objects and entrances to rooms. At the bottlenecks, some deadlocks must occur so that mobile robots cannot move to their goals safely and efficiently. In order to solve this problem, it is necessary for robots working in daily life to give way to the others as humans do. The purpose of this research is to propose a new model for the mobile robot navigation in which the pedestrian intention is modeled with the probabilistic approach and show how important the give-way behavior is for the mobile robot navigation. In this research, we extend the Social Force Model with the intention vector to represent the intention change of the pedestrian and develop a new method to estimate others' intention. By modeling the pedestrian intention with probabilistic appoach, the proposed model solve the deadlocks at the bottleneck and realize the safe and efficient move of mobile robots.

System for Precise Control of Volumetric Flow Rate during Sampling with a Cascade Impactor (2002)

Calculations were made with ef ciency curves developed for the micro-ori ce impactor (MOI) to estimate errors in mass collected on individual stages due to uctuations in the ow rate during sampling of submicrometer particles.The sizes of these errors depend on the size distribution of the sampled aerosol and the level of ow rate uctuation.For a log-normally distributed particle population, mass errors due to ow rate uctuations were bimodally distributed about stages with cutpoints near the aerosol Mass Median Aerodynamic Diameter (MMAD).The largest errors occurred uniformly on the stage with the smallest cutpoint (here, 0.059 m).These errors were asymmetric with respect to sign, which leads to a net error for a randomly uctuating ow rate.In general, mass errors increased with decreasing geometric standard deviation ( g ) and were substantially greater for populations with 0.5 m MMADs than for those with 0.2 m MMADs.The largest net errors for the former were 4, 110, and 560% for g of 1.2 and ow rate uctuations of 1, 5, and 10%, respectively, but decreased to 0.03, 0.9, and 4%, respectively, for a g of 1.9.Flow rate uctuations, therefore, lead to a positive bias in the geometric standard deviation inferred from the measured masses and reduce the user's ability to interpret differences in size distributions.To minimize these effects, we developed and tested a system for controlling the volumetric sampling rate through a MOI at 30 LPM with a precision of 0.06% (600 ms averaging; 0.67% for 5 ms averaging), a level of precision that allows for accurate relative calibration between ow systems and for which errors from ow rate uctuations are reduced to <1%, even for a very narrow aerosol ( g 1.2).Mass errors for an uncontrolled eld test were as large as 60%, but these were reduced to <0.22% in a comparable controlled eld test.In two replicate tests of the system, agreements between stage masses collected on MOI stage 7 (D 50 = 0.173 m) of two simultaneously operated ow-controlled impactors sampling 0.2 m diameter monodisperse test particles were 0.997 and 0.996, although differences as large as 4% were observed for some stages.The system is suitable for use with standard "Federal Reference Method" samplers.

The Role of Hydrogen Atmosphere on the Tribological Behavior of Non-Hydrogenated DLC Coatings against Aluminum (2007)

Diamond-like carbon (DLC) coatings are promising candidates as tool coatings for dry machining of aluminum alloys as aluminum has a lower tendency to adhere to the DLC surface when compared to other hard coatings in ambient conditions. This study investigated the tribological behavior of non-hydrogenated DLC coatings against a 319 Al alloy in various environments including ambient air (47% RH), vacuum (6.65 × 10 − 4 Pa), inert gases (Ar, He, and N 2 ) and a mixture of 60% He-40% H 2 . Unlike the results from the other test conditions, significantly low coefficient of friction (COF) values, ranging between 0.01–0.02, were observed in the 60% He-40% H 2 mixture after a brief period with a high COF of 0.70. The formation of a carbonaceous tribolayer on the counterface and the passivation of the sliding surfaces by the chemisorption of hydrogen were suggested as mechanisms that might have been responsible for the very low COF behavior of the non-hydrogenated DLC coatings in the 60% He-40% H 2 mixture.

Visualization by Dynamic and Static Osseous Scintigraphy of Pelvic Chondrosarcoma in Multiple Hereditary Exostosis (1987)

Malignant degeneration to chondrosarcoma occurred in the left hemipelvis of a patient with multiple hereditary exostosis. Tc-99m HDP bone scintigraphy revealed markedly increased focal uptake in the areas of left superior pubic ramus, obturator foramen, and ischium with displacement of the urinary bladder. Of particular interest was the presence of vascularities seen in the flow and blood pool scintigrams. Following surgical exeresis, the gross appearance and histologic features of the tumor were identified as those of a low grade chondrosarcoma.
Langevin Trajectories between Fixed Concentrations (2005)

We consider the trajectories of particles diffusing between two infinite baths of fixed concentrations connected by a channel, e.g., a protein channel of a biological membrane. The steady state influx and efflux of Langevin trajectories at the boundaries of a finite volume containing the channel and parts of the two baths is replicated by termination of outgoing trajectories and injection according to a residual phase space density. We present a simulation scheme that maintains averaged fixed concentrations without creating spurious boundary layers, consistent with the assumed physics.
Bloody tears: a case of bilateral ulcerative blepharitis (2018)

Chronic blepharitis leading to bilateral ulceration is rare to encounter. A 49-year-old African American female presents with bloody tears, severe pain, and photophobia in both eyes. Clinical presentation called for ulceration on the upper lid margins with excavated wound which bled on gentle rubbing. A systemic health review in combination of the symptoms and clinical picture led to the diagnosis of severe ulcerative blepharitis. Immediate oral antibiotics were started along with topical antibiotic cream. Ulcerative blepharitis can be easily misdiagnosed with sebaceous cell carcinoma. The pathophysiology of ulcerative blepharitis points to synergy between infectious entity and inflammatory aetiology, with either bacterial or fungal microorganisms as the trigger agents. Almost all cases of ulcerative blepharitis should include a dermatological evaluation given there is a strong association between ulcerative blepharitis and atopic dermatitis.

Current-voltage characteristics and noise performance of a static induction transistor for video frequency (1988)

The current-voltage characteristics and the noise properties of the triode-like-mode static induction transistor (SIT) have been examined to estimate the noise performance of the SIT for preamplifier circuits in video frequency regions. Empirical formulas for the current-voltage characteristics and the input equivalent noise resistance have been obtained. A figure of merit for the noise performance of the SIT amplifier is introduced. It is used to determine the operating point at which the noise level becomes minimum.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
