A Generalized Material Averaging Formulation for Modelling of the Electromagnetic Fields (2007)

In this paper, we derive a general electromagnetic material averaging formula for anisotropic inhomogeneous media. In deriving the homogenization formula for the effective medium, we employed the extended Born approximation applied to the Lipmann-Schwinger integral equation for multiple scattering. It is shown that even if the inhomogeneous medium to be averaged is isotropic, the resulting averaged medium can be anisotropic. We further show that, for some special cases, the homogenization formula reduces to well-known material averaging formulas such as the effective medium approximation for spherical inclusions and the Backus averaging formula for finely layered media. The derived averaging formula can be used as a tool to study rock heterogeneities, multiphase structures, as well as an upscaling scheme to assign proper material properties to finite-difference modeling grids when the model under consideration has features that are smaller than the grid size. The latter allows us to use nonconformal grids that will significantly reduce the simulation time of the forward modeling code.

Portable computing for taking part of the lab to the sample types of applications. From hand held personal digital assistants to smart phones for mobile spectrometry (2015)

The use of portable hand held computing devices for the acquisition of spectrochemical data is briefly discussed using examples from the author’s laboratory. Several network topologies are evaluated. At present, one topology that involves a portable computing device for data acquisition and spectrometer control and that has wireless access to the internet at one end and communicates with a smart phone at the other end appears to be better suited for “taking part of the lab to the sample” types of applications. Thus, spectrometric data can be accessed from anywhere in the world.
Fault-tolerant architecture in a cache memory control LSI (1992)

A real-time degradable four-way set-associative cache memory control (CMC) LSI is described. Three kinds of errors, address parity error, comparator error, and multihit error, can cause functional degradation by killing the associative unit corresponding to the fault detection. The parity generator and the double comparator have no effect on the timing-sensitive path delay because of the parallel configuration of the circuits. The multihit detector occupies about 16% of the propagation delay of the critical path, from the external address input to the hit/miss output.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Graves’ hyperthyroidism and thyroiditis in HLA-DRB1*0301 (DR3) transgenic mice after immunization with thyrotropin receptor DNA (2003)

Familial and twin studies in Caucasians have established that the MHC class II allele HLA-DRB1*0301 (DR3) is a strong susceptibility gene in Graves' hyperthyroid disease (GD). To determine if a DR3 transgene could help establish an animal model for GD, we expressed DR3 molecules in class II-knockout NOD mice (H2Ag7-). DR3+g7- mice were given cardiotoxin prior to immunization on weeks 0, 3 and 6 with plasmid DNA encoding human thyrotropin receptor (TSHR). Two groups of mice were also coimmunized with plasmid DNA for IL-4 or GM-CSF. Serial bleeds on weeks 8, 11 and 14 showed that approximately 20% of mice produced thyroid-stimulating antibodies (Abs), and approximately 25% had elevated T4 levels. In particular, a subset displayed both signs of hyperthyroidism, resulting in approximately 30% with some aspect of GD syndrome. Additional mice had thyroid-stimulating blocking Abs and/or TSH-binding inhibitory immunoglobulins, while most mice showed strong labelling of TSHR+ cells by flow cytometry. Interestingly, lymphocytic infiltration with thyroid damage and Abs to mouse thyroglobulin were also noted. Vector controls were uniformly negative. Thus, DR3 transgenic mice can serve as a model for GD, similar to our earlier reports that this allele is permissive for the Hashimoto's thyroiditis model induced with human thyroglobulin.
Wireless Network Infrastructure for Electric Vehicles Communications: Khobar City as a Case Study (2022)

As moving to the EVs is essential due to the environmental cues, we need to solve the problems and undertake the challenges of the EVs to expedite this move. One of these challenges is the long recharging time compared to the traditional refueling process and the consequence of this issue is overcrowding in charging stations. To solve this problem, a charging management system is needed. However, an effective charging management system requires efficient communication networks that facilitate the exchange of information between the EVs, charging stations and the management server. In this work, we study the feasibility of exchanging EV’s data using V2V and V2I communications infrastructure considering Al Khobar city in Saudi Arabia as a case study. SUMO GUI and OMNET++ simulators have been used to set up the environment. The simulation results show that the minimum data throughput requirements are 0.83,1.11, and 59.19 Bytes for V2V, V2I, and I2I respectively. This paper has contributed to finding the minimum requirement of the data throughputs of the communication links in vehicular communication.
KCTD11 inhibits growth and metastasis of hepatocellular carcinoma through activating Hippo signaling (2017)

A lack of effective prognostic biomarkers and molecular targets is a serious problem in hepatocellular carcinoma. KCTD11, reported as a tumor suppressor, are still not well understood. In this study, KCTD11 was found low-expressed in HCC tissues and cell lines. The HCC patients with low expression of KCTD11 suggested shorter overall survival. We found KCTD11 inhibiting cell proliferation in vitro and tumor growth in vivo, by activating p21 and repressing cycle related proteins. KCTD11 also inhibited cell adhesion by decreasing CTGF and CLDN1. We found CTGF binding COL3A1 in HCCLM3, which might lead to reduction of COL3A1 expression. KCTD11 also inhibited cell migration and invasion in HCC, by repressing MMPs and EMT. We found the tumor suppression function of KCTD11 was at least partly through activating Hippo pathway in HCC. Base on the enhanced Hippo pathway, KCTD11 could activate p21 by stabilizing p53 or promoting the MST1/ GSK3β/p21 signaling in HCC. Overall, these results suggest that KCTD11 works as a tumor suppressor and owns prognostic and therapeutic potentials in HCC.
Jackup Rig Foundation Modeling II (1993)

ABSTRACT As part of an on-going research effort, drum centrifuge tests of three-leg jack-up rigs on sand and clay seabeds have been used to improve an elastic-plastic work-hardening model for jack-up foundations previously proposed [6]1. This paper constitutes an interim research progress report. The spud can secant fixity for sand was found to vary from 0.6 to 0.9 (on a scale of 0.0 to 1.0 proposed herein) and is consistent with field measurements [3]. The inferred secant elastic rotational modull for loose and dense sands differ by a factor of 1.3 to 1.7 and both are significantly greater than those determined in single-leg tests [6]. The secant fixity and modull for clay during 2-way cyclic loading degrade to asymptotic values within the first 10 to 20 loading cycles. The relative magnitudes of modulus degradation are consistent with previous findings [4], which were based on field measurements. However, the effects of cyclic loading on tangent fixity and modulus are inconclusive. A simple hyperbolic model with asymptotic behavior based on theories [1, 2] only slightly underpredicts the interpreted moment-rotation response of spud cans in clay. INTRODUCTION The response of an independent leg jack-up to environmental loading is highly sensitive to foundation behavior, especially the rotational "fixity" of the spud can. Two key response variables, deck-leg moment and natural period of the structure, are directly affected by the foundation fixity condition. To investigate this problem experimentally, a geotechnical drum centrifuge, which provides properly scaled model tests of three-leg jack-up rigs subjected to lateral loading, was used. The results reported herein are intended to extend previous work on this topic [5, 6] and to provide an interim progress report on an ongoing experimental research program. In this study, the results of extensive drum centrifuge tests on three-leg jack-up rig models supported on uniform sand (loose and dense) and clay seabeds are examined. In particular, the sub-yield behavior of the spud can rotational response is extracted, which may serve as a rough guideline in the selection of "elastic" input parameters to the elastic-plastic work-hardening foundation model previously proposed [6]. Note that the "elastic" properties represent idealized behavior and are not truly elastic. The elastic rotational response due to horizontal loading is interpreted in terms of spud can fixity, which is the ratio of the actual moment at the mudline to the theoretical moment of a spud can that is fully fixed against rotation. The rotational stiffness (and hence "elastic" modulus) can then be determined since it is a unique function of fixity, The use of spud can fixity to estimate the elastic rotational modulus circumvents the uncertainties associated with the use of very small spud can displacements (fractions of a millimeter) inferred from transducer measurements, which was a drawback with single- Ieg tests [5, 6, 7]. The inferred modull for loose and dense sands are compared with the empirical relationships derived from single-leg test results [6, 7].
Spectral Total-Variation Processing of Shapes: Theory and Applications (2022)

We present an analysis of total-variation (TV) on non-Euclidean parameterized surfaces, a natural representation of the shapes used in 3D graphics. Our work explains recent experimental findings in shape spectral TV [Fumero et al., 2020] and adaptive anisotropic spectral TV [Biton and Gilboa, 2022]. A new way to generalize set convexity from the plane to surfaces is derived by characterizing the TV eigenfunctions on surfaces. Relationships between TV, area, eigenvalue, eigenfunctions and their discontinuities are discovered. Further, we expand the shape spectral TV toolkit to include versatile zero-homogeneous flows demonstrated through smoothing and exaggerating filters. Last but not least, we propose the first TV-based method for shape deformation, characterized by deformations along geometrical bottlenecks. We show these bottlenecks to be aligned with eigenfunction discontinuities. This research advances the field of spectral TV on surfaces and its application in 3D graphics, offering new perspectives for shape filtering and deformation.
Origins of Electronic Band Gap Reduction inCr/NCodopedTiO2 (2014)

Recent studies indicated that noncompensated cation-anion codoping of wide-band-gap oxide semiconductors such as anatase TiO2 significantly reduces the optical band gap and thus strongly enhances the absorption of visible light [W. Zhu et al., Phys. Rev. Lett. 103, 226401 (2009)]. We used soft x-ray spectroscopy to fully determine the location and nature of the impurity levels responsible for the extraordinarily large (∼1 eV) band gap reduction of noncompensated codoped rutile TiO2. It is shown that Cr/N codoping strongly enhances the substitutional N content, compared to single element doping. The band gap reduction is due to the formation of Cr 3d3 levels in the lower half of the gap while the conduction band minimum is comprised of localized Cr 3d and delocalized N 2p states. Band gap reduction and carrier delocalization are critical elements for efficient light-to-current conversion in oxide semiconductors. These findings thus raise the prospect of using codoped oxide semiconductors with specifically engineered electronic properties in a variety of photovoltaic and photocatalytic applications.
Model-driven sketch reconstruction with structure-oriented retrieval (2016)

We propose an interactive system that aims at lifting a 2D sketch into a 3D sketch with the help of existing models in shape collections. The key idea is to exploit part structure for shape retrieval and sketch reconstruction. We adopt sketch-based shape retrieval and develop a novel matching algorithm which considers structure in addition to traditional shape features. From a list of retrieved models, users select one to serve as a 3D proxy, providing abstract 3D information. Then our reconstruction method transforms the sketch into 3D geometry by back-projection, followed by an optimization procedure based on the Laplacian mesh deformation framework. Preliminary evaluations show that our retrieval algorithm is more effective than a state-of-the-art method and users can create interesting 3D forms of sketches without precise drawing skills.

Guideline-Driven Management of Hypertension (2021)

Several important findings bearing on the prevention, detection, and management of hypertension have been reported since publication of the 2017 American College of Cardiology/American Heart Association Blood Pressure Guideline. This review summarizes and places in context the results of relevant observational studies, randomized clinical trials, and meta-analyses published between January 2018 and March 2021. Topics covered include blood pressure measurement, patient evaluation for secondary hypertension, cardiovascular disease risk assessment and blood pressure threshold for drug therapy, lifestyle and pharmacological management, treatment target blood pressure goal, management of hypertension in older adults, diabetes, chronic kidney disease, resistant hypertension, and optimization of care using patient, provider, and health system approaches. Presenting new information in each of these areas has the potential to increase hypertension awareness, treatment, and control which remain essential for the prevention of cardiovascular disease and mortality in the future.
Experimental investigation of the strain rate dependent impact behaviour of cementitious composites (2002)

As for most construction materials, cementitious composites exhibit a strain rate dependent mechanical behaviour. The frequent occurrence of impact loads during the lifetime of civil engineering constructions makes the experimental research into the impact properties of construction materials sensible. To this purpose split Hopkinson bar tests are often used. However, due to the specific behaviour of plain cementitious materials—low strains and softening—special attention has to be paid to some aspects of the experimental setup, the treatment of the recorded signals and the interpretation of the final results. Some results of impact tensile tests on microconcrete are presented. These results show that the strength, the strain at maximum stress, the ultimate deformation and the energy absorbing capacity are higher than in static test conditions.
Compressing and shearing the transplanted kidney (2016)

Kidney transplantation is one treatment for end-stage renal disease. Transplant rejection is typically evaluated with an invasive biopsy. Noninvasive methods for evaluating renal transplants would be beneficial for frequent evaluation. We propose the use of shear wave elastography (SWE) to evaluate viscoelastic properties in renal transplants. Further, we also use acoustoelasticity to measure the nonlinear modulus of the renal transplants. Acoustoelasticity is the phenomenon where the shear wave velocity (SWV) in a material varies with applied stress and is quantified by a nonlinear modulus, A. By applying pressure with the ultrasound transducer, stress is applied to the kidney under investigation and B-mode imaging was used to measure induced strain and SWE was used to make measurements of SWV. Using relationships involving the measured strain and shear moduli at different compression levels, we can obtain estimates of A. In our ongoing study, we use a General Electric Logiq E9 to perform SWE measurements in renal transplant patients coming for protocol biopsies. We have studied 63 patients with SWE to quantify viscoelastic properties of the transplanted kidney. We have obtained data from 19 patients for estimation of the nonlinear modulus, A. We compared the measured viscoelastic and nonlinear shear parameters with clinical variables such as the serum creatinine, Banff biopsy scores, and resistive index. We continue to evaluate these methods and their efficacy as indicators for transplant rejection.

Campomelic Dysplasia: Airway Management in Two Patients and an Update on Clinical-Molecular Correlations in the Head and Neck (2011)

Campomelic dysplasia is a rare and historically lethal skeletal dysplasia with a variable but recognizable phenotype; it affects the long bones and is associated with a variety of head and neck anomalies. Mutations in or around the SOX9 gene have been identified as the molecular origin in most patients. We briefly present 2 children who meet the diagnostic criteria for campomelic dysplasia to illustrate the various clinical manifestations. Many patients with campomelic dysplasia have airway obstruction at multiple levels. We describe our approach to managing the airway in these patients, and review recent advances in understanding how SOX9 mutations lead to the spectrum of abnormalities seen in the head and neck.
Fundamental Optical Design (2001)

The history of optical design has engendered theoretical work originating in different countries, and using different nomenclature and sign conventions. Michael Kidger was adept at selecting topics that would be useful in the mainstream of optical design, reducing theory to the essentials and rewriting it using a common nomenclature and sign convention. This work, published after Kidger's death with the help of his colleagues, provides all the essential and best elements of his courses taught worldwide on lens and optical design.
INDIVIDUAL VOLATILE ACIDS IN ANAEROBIC TREATMENT (2016)

In anaerobic waste treatment one of the most important indications of unbalanced conditions is an increase in the volatile acids concentrations. Recently the development of rapid Chromatographie procedures has stimu lated an interest in identifying the individual volatile acids formed and determining their relative concentra tions during digester upset. Such identification may improve the under standing of the complex biochemistry of anaerobic digestion. Equally im portant, identification of the individ ual acids formed under upset condi tions may furnish clues to the reason for digester unbalance and thus prove an important tool for control of anaer obic waste treatment processes. Most of the studies reported to date have been concerned with digestion of mixed organic wastes and interpreta tion has been difficult due to lack of knowledge of the importance of the individual acids formed during unbal anced conditions. For this reason this study was conducted to determine the
Influence of Deposition Temperature, Gas Pressure, Gas Phase Composition, and RF Frequency on Composition and Mechanical Stress of Plasma Silicon Nitride Layers (1985)

We have studied the influence of different process parameters on the composition and mechanical properties of silicon‐nitride layers deposited in a plasma. The layers were deposited at temperatures between 300° and 600°C, at total pressures between 65 and 195 Pa and RF frequencies between 0.1 and 20 MHz. The Si/N ratio and the density of the as‐deposited layers were determined by means of RBS. IR spectroscopy was used to measure the hydrogen content and Si‐H/N‐H ratio of the plasma nitride layers. It is shown that hydrogen content, density, and mechanical stress of plasma silicon‐nitride layers strongly depend on deposition conditions. To explain the experimental data, a simplified reaction model is given. With this model, differences in densities, hydrogen content, and stress can be related to cross‐linking reactions and to the extent of ion bombardment which takes place at different excitation frequencies.
