Refractive Errors, Axial Ocular Dimensions, and Age-Related Cataracts: The Tanjong Pagar Survey (2003)

These population-based data support the associations between nuclear and posterior subcapsular cataracts and myopia reported in previous studies. Posterior subcapsular cataract is also associated with deeper anterior chamber, thinner lens, and longer vitreous chamber, with vitreous chamber depth explaining most of the association between posterior subcapsular cataract and myopia.
Boundary lubrication of articular cartilage: Role of synovial fluid constituents (2007)

The results described here indicate that SF constituents contribute, individually and in combination, both at physiologic and pathophysiologic concentrations, to the boundary lubrication of apposing articular cartilage surfaces. These results provide insight into the nature of the boundary lubrication of articular cartilage by SF and its constituents. They therefore provide insight regarding both the homeostatic maintenance of healthy joints and pathogenic processes in arthritic disease.
Scoliosis corrective force estimation from the implanted rod deformation using 3D-FEM analysis (2015)

Corrective force during scoliosis surgery was demonstrated to be about four times greater in the concave side than in convex side. Averaged pull out and push in force fell below previously reported safety margin. Therefore, the SDRRT maneuver was safe for correcting moderate magnitude curves. To prevent implant breakage or pedicle fracture during the maneuver in a severe curve correction, mobilization of spinal segment by releasing soft tissue or facet joint could be more important than using a stronger correction maneuver with a rigid implant.
Influence of Growth Temperature and Thickness of AlGaN Caps on Electron Transport in AlGaN/GaN Heterostructures Grown by Plasma-assisted Molecular Beam Epitaxy (2001)

The influence of Al 0.05 Ga 0.95 N cap thickness and growth temperature on the electrical properties of the Al 0.05 Ga 0.95 N/GaN two-dimensional electron gas (2DEG) was investigated. Varying the thickness of the Al 0.05 Ga 0.95 N barrier led to regions in which the dominant 2DEG scattering mechanisms were either Coulombic or interface roughness/alloy disorder scattering. The 2DEG sheet carrier concentration was found to increase with Al 0.05 Ga 0.95 N cap thickness and saturated at ∼ 25 nm. By increasing the growth temperature from 650°C to 750°C, the measured low temperature 2DEG sheet carrier concentration was found to decrease and the measured low temperature mobility was found to increase while the Al composition remained constant. Temperature dependent Hall measurements revealed that by increasing the growth temperature, the incorporation of impurities is decreased. A maximum 77 K mobility of ∼ 19,000 cm 2 /Vs was observed for films grown at 750°C with 20 nm thick Al 0.05 Ga 0.95 N caps.
A Real-Time Millimeter-Wave Phased Array MIMO Channel Sounder (2017)

In this paper, we present a novel real-time MIMO channel sounder for 28 GHz. Until now, the common practice to investigate the directional characteristics of millimeter-wave channels has been using a rotating horn antenna. The sounder presented here is capable of performing horizontal and vertical beam steering with the help of phased arrays. Thanks to the fast beam-switching capability, the proposed sounder can perform measurements that are directionally resolved both at the transmitter (TX) and receiver (RX) as fast as 1.44 milliseconds compared to the minutes or even hours required for rotating horn antenna sounders. This does not only enable us to measure more points for better statistical inference but also allows us to perform directional analysis in dynamic environments. Equally important, the short measurement time combined with the high phase stability of our setup limits the phase drift between TX and RX, enabling phase-coherent sounding of all beam pairs even when TX and RX are physically separated and have no cabled connection for synchronization. This ensures that the measurement data is suitable for high-resolution parameter extraction algorithms. Along with the system design and specifications, this paper also discusses the measurements performed for verification of the sounder. Furthermore, we present sample measurements from a channel sounding campaign performed on a residential street.
El Mestre Ramon Torroja i Valls : carta des de la presó = Teacher Ramon Torroja i Valls : a letter from jail (2009)

L'ocupacio de Catalunya pels revoltats contra la Republica, el 1939, va provocar la
sortida cap a Franca de milers i milers de persones. Entre aquestes hi havia una bona
colla de mestres, homes i dones; mes del 10% del magisteri que treballava al pais. Ben
segur que el fet que Catalunya fos un pais de frontera va afavorir aquesta sortida.
No tothom decidi marxar cap a Franca quan s'acostava l'exercit franquista. Va
haver-hi persones democratiques, catalanes, d'ideals republicans que creien que seria
possible continuar vivint aqui, malgrat que les condicions no serien les optimes; pero
la realitat, la dura realitat, s'encarrega de demostrar que aixo no seria aixi.
Les presons es varen omplir. Un dels tancats va ser el mestre i director de l'escola
Annexa de la Normal de la Generalitat, Ramon Torroja Valls, una de les personalitats
pedagogiques mes importants (i lamentablement poc conegudes), tant per la seva tasca
educadora com per la influencia que va exercir en una part dels futurs mestres.
Tancat a la preso Model de Barcelona, el 1939, aprofita l'aniversari de la seva filla
Nuria i li adreca una carta el 1940 explicant la vida a l'interior del penal. Un text

On the Wireless Transmitters Linear and Nonlionear Distortions Detection and Pre-Correction (2006)

Linear and nonlinear distortions that manifested along the wireless transmitter scheme are of great importance since they influence the communication link performance. This paper proposes a comprehensive study of these distortions through the investigation of their sources and the means to characterize them for pre-correction purposes. Both long term and short term linear distortion are concerned in this paper. Measurement results conducted on typical 100Watt wireless UMTS transmitter point out the benefit of a concurrent pre-compensation for both linear and nonlinear distortion effects using digital baseband predistortion technique

Additives Co-Injection: A Test for Determining the Efficacy and Process Parameters of Bottom-up Plating (2016)

The additives co-injection test is shown to provide important and unique insight into the bottom-up plating process. The observed transient peak polarization depends on the convective flow and reflects the electrode coverage by both the suppressor and the anti-suppressor species, much like the electrode coverage during the actual bottom-up plating process. A computer implemented analytical model of the co-injection test is presented. This model, which accounts for the additives transport through the flow-induced boundary layer and their adsorption kinetics, characterizes the actual wafer plating process more comprehensively than previous models, linking for the first time the wafer rotation rate to the process effectiveness. Correlating the model to experimental data provides the values of process parameters, including additives adsorption rates and their displacement constants, which heretofore were not accessible. It is found that previously reported values of diffusivities, saturated surface coverages, and the SPS adsorption rate constant are consistent with the presented co-injection model, however, values for the rate constants of PEG adsorption (kPEG) and PEG displacement by SPS (kSPS,PEG), which previously have only been inaccurately estimated, are now correctly quantified. The newly derived values are 10 cm/s and 2.0 × 10−6 cm/s for kPEG and kSPS,PEG, respectively.
Preparation of liquid-crystal thermosets:In situ photopolymerization of oriented liquid-crystal diacrylates (1999)

The photoinitiated polymerization of 2-chloro-1,4-phenylene bis[4-[6-(acryloyloxy)hexyloxy]benzoate] (1M) was studied. The monomer 1M exhibited a broad nematic phase between 24.9 and 113.7 °C on a DSC cooling scan. It was oriented in its nematic phase at a substrate coated with polyimide and unidirectionally rubbed with a nylon cloth. During polymerization, the ordering of the liquid–crystal molecules was fixed, yielding a uniaxially crosslinked network. The clear liquid–crystal networks (LCNs) exhibited a birefringence between 0.14 and 0.19, depending on the polymerization temperature. Finally, a nonmesogenic diluent, tetra(ethylene glycol)diacrylate, was mixed with 1M, subsequently decreasing the birefringence of the obtained LCNs. The LCNs containing nonmesogenic diluent exhibited not only a smaller birefringence but also a weaker birefringence dispersion in the visible region. © 1999 John Wiley & Sons, Inc.

Stimulated emission from GaN nanocolumns (2004)

Abstract Stimulated emission with very low threshold excitation power density was observed for GaN nanocolumns grown on (0001) sapphire substrate by RF‐plasma assisted molecular beam epitaxy. The photopump measurements were carried out under 355 nm Nd:YAG laser excitation with the surface emission configuration. The threshold excitation power density was 198 kW/cm 2 at room temperature. The peak wavelength shifted from 370.2 to 370.9 nm when increasing the excitation power from 130 to 440 kW/cm 2 . The peak intensity increased nonlinearly with excitation power. For the lower excitation condition using a 325 nm He–Cd laser, the spontaneous emission peak was observed at 363.2 nm and the intensity was 20∼30 times stronger than for a 3.7 μm‐thick MOCVD‐grown GaN film with a dislocation density of 3∼5 × 10 9 cm –2 . With this configuration the peak intensity was increased propotionally with excitation power. These results indicate that GaN nanocolumns have high potential to realize high performance optical devices. (© 2004 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)
A new tri-Fab recombinant bispecific antibody (bsMAb) for pretargeting epithelial cancers: Studies with TF12 and 111In-labeled hapten-peptide (IMP 288) in ovarian cancer (2010)

1148 Objectives Bispecific antibody pretargeting is a highly sensitive and specific method for detecting and treating cancers with radiolabeled hapten-peptides. Using the Dock-and-Lock technology, we developed a new tri-Fab bsMAb specific for an antigen highly expressed on epithelial cancers, epithelial glycoprotein-1 (aka TROP-2), which reacts with monoclonal antibody, RS7. Since RS7 internalizes, we evaluated its potential for pretargeting with the TF12 bsMAb in a model of ovarian cancer. Methods ICR SCID female mice bearing sc SKOV-3 human ovarian cancer xenografts were injected iv with TF12 (155 µg; ~1 nmol) followed 22 h later with 0.05 nmol 111In-IMP-288 iv. Mice were necropsied at 3 and 24 h post peptide injection. A second group received the peptide alone. For comparison, another group of mice were injected iv with 111In-DTPA-hRS7 IgG. Results ICR SCID mice were found to have variable clearance of the bsMAb and thus considerable variability was encountered with 111In-IMP-288 in the blood, particularly at early intervals. Nevertheless, in the pretargeting group, tumor uptake of the 111In-IMP-288 was 20.4±5.5% and 21.7±2.6 % ID/g, and blood concentration was 9.2±9.9% and 0.09±0.145 % ID/g at 3 and 24 h post-peptide injection, respectively. At 3 h post injection, the peptide alone group had tumor uptake and blood concentrations of 0.36±0.164% and 0.021± 0.03, respectively. The intact IgG showed tumor targeting, 20.0±4.8% ID/g and blood concentrations of 14.8±4.5% ID/g 3 days after injection. Conclusions Despite the internalizing properties of the TF12 bsMAb, high uptake and retention of the pretargeted 111In-IMP-288 was possible in the SKOV-3 ovarian cancer model. This pretargeting system has the potential for use in imaging and therapy of ovarian cancer with radionuclides and drugs.

Inferring work by quantum superposing forward and time-reversal evolutions (2022)

The study of thermodynamic fluctuations allows one to relate the free energy difference between two equilibrium states with the work done on a system through processes far from equilibrium. This finding plays a crucial role in the quantum regime, where the definition of work becomes nontrivial. Based on these relations, here we develop a simple interferometric method allowing a direct estimation of the work distribution and the average dissipative work during a driven thermodynamic process by superposing the forward and time-reversal evolutions of the process. We show that our scheme provides useful upper bounds on the average dissipative work even without full control over the thermodynamic process, and we propose methodological variations depending on the possible experimental limitations encountered. Finally, we exemplify its applicability by an experimental proposal for implementing our method on a quantum photonics system, on which the thermodynamic process is performed through polarization rotations induced by liquid crystals acting in a discrete temporal regime.
First-principles calculation of the exchange interaction and the exchange force between magnetic Fe films (1997)

First-principles calculations have been performed for the exchange interaction and the exchange force between two magnetic Fe(100) thin films. It is shown that the magnitude of the calculated exchange force is of the order of ${10}^{\ensuremath{-}9}N$ at $d/a&lt;1$ and of the order of ${10}^{\ensuremath{-}10}N$ at $1&lt;d/a&lt;1.5$, where $d$ denotes the distance between surfaces of the two thin films and $a$ the lattice constant of bulk Fe. The obtained forces are sufficiently larger than the sensitivity of the current atomic force microscopy of ${10}^{\ensuremath{-}12}\ensuremath{-}{10}^{\ensuremath{-}13}N$, which suggests the feasibility of the exchange force microscopy.
FTIR imaging detects diet and genotype-dependent chemical composition changes in wild type and mutantC. elegansstrains (2017)

This study focuses on the use of Fourier Transform Infrared (FTIR) microspectroscopy to determine chemical changes induced in the nematode Caenorhabditis elegans by supplementation of C. elegans maintenance media (CeMM) by Eicosapentaenoic acid (EPA). Wild-type C. elegans (N2) and mutant strains (tub-1 and fat-3) were grown in CeMM alone, and CeMM supplemented with EPA at 25 or 100 μM. Feeding was performed for 72 h. FTIR imaging was performed in transmission mode on individual worms. The FTIR imaging analysis of wild-type animals revealed the presence of vibrations assigned to unsaturated fatty acids, specifically bands at 3008 cm<sup>-1</sup> ([double bond, length as m-dash]C-H, olefinic stretch) and 1744 cm<sup>-1</sup> (C[double bond, length as m-dash]O, unsaturated fatty acids). It confirmed previously reported synthesis of unsaturated fatty acids in wild-type C. elegans. For the FTIR spectra of mutant strains, these vibrations were absent or present only as very small shoulder, which indicates that tub-1 and fat-3 synthesize essentially saturated fatty acids as indicated by the presence of -CH<sub>2</sub> and C[double bond, length as m-dash]O vibrations. These results are in agreement with previous studies which reported that these mutants have altered lipid compositions. Principal component analysis showed differences in chemical composition between wild-type and mutant strains as well as between mutant strains cultured in normal CeMM and those cultured in CeMM supplemented with EPA. This study demonstrated the usefulness of FTIR microspectroscopy to investigate fat metabolism in C. elegans.
A numerical absorbing boundary condition for finite‐difference and finite‐element analysis of open structures (1994)

Abstract In this article we present a novel approach to deriving local boundary conditions that can be employed in conjunction with the finite‐difference and finite‐element methods (FD/FEM) to solve electromagnetic scattering and radiation problems. The key step in this approach is to derive linear relationships that link the values of the field at the boundary grid points to those at the neighboring points. These linear relationships are satisfied, to within a certain tolerance, by all of the outgoing wave components. They can thus be used in lieu of the FD/FEM equations employing the usual absorbing boundary conditions for the boundary points. The present approach not only provides a simple way to derive an accurate boundary condition for mesh truncation, but also preserves the banded structure of the FD/FEM matrices. © 1994 John Wiley &amp; Sons, Inc.

Optimizing the Gel Strength of Water-Based Drilling Fluid Using Clays for Drilling Horizontal and Multi-Lateral Wells (2018)

Abstract Drilling fluid constitutes an important part of the drilling operations. Drilling mud is circulated into the wellbore to minimize the formation damage, transport cuttings from the bottom to the top of the well, cool and lubricate the bit, and maintain the stability of shale formations. Gel strength property of drilling fluids plays a key role in drilling multilateral and long horizontal reservoir sections. Losing the gel strength will accumulate drilled cuttings and as a result, sticking of the drill string. Solving this issue takes a long time and increase the total cost of the drilling operation. It was observed that, by increasing the temperature to 200°F, the gel strength of calcium carbonate water-based drilling fluid reached zero lb/100 ft2. The objectives of this paper are to: (1) determine the rheological properties of calcium carbonate water- based drilling fluid over a wide range of temperature, (2) assess the effect of using clays (bentonite) to solve the gel strength problem associated with the current field formulation of calcium carbonate water- based drilling fluids, and (3) optimize the weight percent of bentonite. Rheological properties such as the apparent viscosity, plastic viscosity, yield point and gel strength were measured by using a high-pressure high-temperature rheometer. At low temperatures (85°F), the calcium carbonate water-based drilling fluid showed no change in the gel strength with time. However, at high temperatures, the gel strength starts decreasing with time. Rheological properties confirmed that the gel strength of the calcium carbonate water-based drilling fluid reached zero lb/100 ft2 by increasing the temperature to 200°F. This issue was solved by adding different concentrations of bentonite. The bentonite concentration was varied from 3 wt.% to 10 wt.%. At low bentonite concentrations (3.33 wt.%), the gel strength still reduced with time. At high bentonite concentration (10 wt.%), the gel strength increased with time. The optimum concentration of bentonite was 6.66 wt.%, which yielded a flat rheology profile of the gel strength. These results confirmed that the rheological properties of the water-based drilling fluid were optimized by using clays (bentonite). The novelty of this research is the complete investigation of the drilling fluid properties especially the gel strength with time over a wide range of temperature. The results obtained can leads to the development of a cheap solution without any side effect.
Resin activation capture technology: Libraries from stabilized acyl-pyridinium on solid support (2000)

REsin Activation/Capture APproach or REACAP Technology, a novel approach to the synthesis of compound libraries, capitalizes on the formation and retention of a resin-bound reactive intermediate, which can be subsequently transformed into a stable, covalently attached molecule. Any unreacted "reactive intermediate" is quenched and removed from the resin upon work-up, leaving only the desired product on the solid support. In contrast to more traditional solid-supported chemistry that must address issues such as resin-loading, capping of unreactive functionalized moieties, and reaction yields, REACAP offers an attractive alternative with the focus more on the purity of the released products and less on yield. In an endeavor to generate truly non-peptide leads, we describe herein the synthesis of N-acyl-2-substituted-dihydro-4-pyridones, dihydro-4-pyridones, 4-ketopiperidines, tetrahydropyridines, and 2-acyl-3,7,8-substituted-5-oxo-2-azabicyclo[2.2.2]octane and triaza analogs using REACAP Technology.
Assessment of different pillar geometries for 1-3 composite transducers using finite element analysis (2002)

Composite piezoelectric transducers, comprising piezoceramic pillars aligned within a polymer matrix, exhibit a high electromechanical coupling coefficient and a low acoustic impedance. Finite element analysis is used to investigate the dependence of device performance, in terms of electromechanical efficiency and vibrational uniformity, on pillar geometry. Results obtained by using alternative pillar shapes, including circular, square, and triangular geometries, are discussed, and an overall design strategy is formulated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
