Research on Calculation of the IOL Tilt and Decentration Based on Surface Fitting (2013)

The tilt and decentration of intraocular lens (IOL) result in defocussing, astigmatism, and wavefront aberration after operation. The objective is to give a method to estimate the tilt and decentration of IOL more accurately. Based on AS-OCT images of twelve eyes from eight cases with subluxation lens after operation, we fitted spherical equation to the data obtained from the images of the anterior and posterior surfaces of the IOL. By the established relationship between IOL tilt (decentration) and the scanned angle, at which a piece of AS-OCT image was taken by the instrument, the IOL tilt and decentration were calculated. IOL tilt angle and decentration of each subject were given. Moreover, the horizontal and vertical tilt was also obtained. Accordingly, the possible errors of IOL tilt and decentration existed in the method employed by AS-OCT instrument. Based on 6-12 pieces of AS-OCT images at different directions, the tilt angle and decentration values were shown, respectively. The method of the surface fitting to the IOL surface can accurately analyze the IOL's location, and six pieces of AS-OCT images at three pairs symmetrical directions are enough to get tilt angle and decentration value of IOL more precisely.
Benzenesulfonamides with different rigidity-conferring linkers as carbonic anhydrase inhibitors: an insight into the antiproliferative effect on glioblastoma, pancreatic, and breast cancer cells (2022)

Among the chemotypes studied for selective inhibition of tumour-associated carbonic anhydrases (CAs), <b>SLC-0111</b>, a ureido-bearing benzenesulfonamide CA IX inhibitor, displayed promising antiproliferative effects in cancer cells <i>in vitro</i> and <i>in vivo</i>, being in Phase Ib/II clinical development. To explore the structural characteristics required for better discrimination of less conserved regions of the enzyme, we investigate the incorporation of the urea linker into an imidazolidin-2-one cycle, a modification already explored previously for obtaining CA inhibitors. This new library of compounds inhibited potently four different hCAs in the nanomolar range with a different isoform selectivity profile compared to the lead <b>SLC-0111</b>. Several representative CA IX inhibitors were tested for their efficacy to inhibit the proliferation of glioblastoma, pancreatic, and breast cancer cells expressing CA IX, in hypoxic conditions. Unlike previous literature data on <b>SLC-149</b>, a structurally related sulphonamide to compounds investigated here, our data reveal that these derivatives possess promising anti-proliferative effects, comparable to those of <b>SLC-0111</b>.

Combination of current-integrating/photon-counting detector modules for spectral CT (2013)

Inspired by compressive sensing theory and spectral detection technology, here we propose a novel design of a CT detector array that uses current-integrating/photon-counting modules in an interlacing fashion so that strengths of each detector type can be synergistically combined. For geometrical symmetry, an evenly alternating pattern is initially assumed for these detector modules to form a hybrid detector array. While grayscale detector modules acquire regular raw data in a large dynamic range cost-effectively, spectral detector modules simultaneously sense energy-discriminative data in multiple energy bins. A split Bregman iterative algorithm is developed for spectral CT reconstruction from projection data of an object collected with the hybrid detector array. With mathematical phantoms, an optimal ratio of the number of the spectral elements over the number of grayscale elements is determined based on classic image quality evaluation. This hybrid detector array is capable of delivering a performance comparable with that of a full spectral detector array.
Beam Synthesis with Low-Bit Reflective Coding Metamaterial Antenna: Theoretical and Experimental Results (2018)

Coding metamaterials are the new technology where the aperture coding provides the hardware foundation for the miniaturization of the devices. As a synthetic 2-D plane, metamaterial antennas are composed of subwavelength resonant particles. It can realize real-time control of electromagnetic wave and build multifunction radar array system. We make a detailed explanation of its array structure, working principle, and hardware system. However, it is usually difficult to synthesize flexible beams because the phase value is very limited in this antenna. Two methods are proposed in this paper to demonstrate the beam synthesis based on repetitive coding and convolution, and the distribution of beam pointings is analysed on the basis of this mechanism. Experiments that measure the radiation pattern of this antenna are carried out to verify the simulated results using only 1-bit coding metasurface in a radar system, whose phase value is controlled by pin diode on the surface.

A pressure mat for preventing pressure sores (2003)

Using a 0.4-mm thick Interlink conductive polymer pressure sensor, the pressure distribution under the buttocks was measured. The measured pressures under the ischial tuberosities were much higher when the subject was seated on a table than when seated on a cushion. A pressure mat incorporating an array of these sensors, to be placed under any bony protuberance, is proposed. When the pressure-time profile of any sensor exceeds safe limits, an alarm would be provided to the patient or caregiver. It is believed that this pressure mat could reduce the incidence of pressure sores in the spinal-cord injured, in the elderly, and in the operating room.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Effects of photoenhanced toxicity of anthracene on ecological and genetic fitness of daphnia magna: A reappraisal (1991)

Abstract Holst and Giesy [1] reported photoenhanced effects of anthracene exposure on reproduction of Daphnia magna in terms of total clutch size and survival over a 21-d period. A reappraisal of those experiments, using additional data regarding time to first brood, average size of first brood and the intrinsic rate of increase, rm, for exposures with and without anthracene and/or ultraviolet radiation (UVR), reveals that inferred impacts on genetic fitness as exemplified by rm are significant only for the highest exposure tested, whereas ecological fitness, measured by the time to first brood, was unimpaired at any combination of UVR and anthracene.
Properties of interconnection on silicon, sapphire, and semi-insulating gallium arsenide substrates (1982)

Interconnection capacitances and inductances on oxide-passivated silicon, sapphire, and semi-insulating gallium arsenide substrates were calculated and compared. The results showed that, including coupling effects, the capacitances on insulating substrates are lower only at large linewidths, but become comparable to values on silicon substrates at linewidths below 2.5 µm. The frequency-dependent nature of inductances on silicon substrates was reviewed. The results indicated that, at frequencies where most digital integrated circuits operate, silicon substrates can be treated as a lossless medium. Hence, inductances on silicon substrates can be calculated by the same means as on insulating substrates. The propagation delay of an interconnection resulting from using different substrates was also evaluated. It can be shown that for VLSI development the choice of substrates is not nearly as critical as the problem of series resistance of an interconnection.
3-D Joint Reaction Forces at the Glenohumeral Joint During Active Motion (1998)

Abstract Previous studies, using imaging techniques[4] and mathematical models, have predicted that loads up to 90% of body weight are transmitted across the glenohumeral (GH) joint at 90° of abduction[2, 3]. However, in comparison to weight-bearing joints like the hip and knee, there is little quantitative data describing 3-D reaction forces generated at the GH joint during active motion. This information is important to our understanding of GH joint function in both normal and pathological conditions. It can also provide an experimental validation for computational models of the GH joint.
Metabolic activation in the fetal mouse salivary gland culture system with rat hepatocytes, rat S‐9, and human S‐9 (1991)

The usefulness of an in vitro assay for embryotoxicity may depend on the availability of metabolic activation systems that will function in the culture system. The fetal mouse salivary gland has been investigated as an in vitro assay system. To see if the glands would grow in the presence of metabolic activators and if the glands would react to metabolites known to be embryotoxic, the glands were grown in the presence of cyclophosphamide (CP) and several activation systems. These included isolated rat hepatocytes, uninduced rat S-9, rat S-9 induced with 3-methylcholanthrene (3-MC), rat S-9 induced with Aroclor 1254, and human S-9. Twenty salivary glands were isolated from 13 day embryos (plug day = 0) and were grown in each treatment for 48 h. One control had no activation system of CP, one had an activation system but no CP, and three treatments had the activation system and 25, 75, or 150 micrograms/ml CP. The S-9 with cofactors and the appropriate amount of CP was contained in dialysis bags. The greatest suppression of salivary gland growth occurred in co-culture with hepatocytes activating CP. The S-9 induced by Aroclor 1254 was nearly as effective as the hepatocytes. The next most effective was a group with similar activity consisting of the uninduced rat S-9 and the three samples of human S-9. The 3-MC-induced S-9 was the least effective in suppressing growth of salivary glands. All the activation systems tested can be used with the salivary gland culture system.
Multidecadal evaluation of changes in coffee-growing areas using Landsat data in Central Highlands, Vietnam (2023)

Vietnam is the world’s second-largest coffee exporter. Information on coffee-growing areas is thus important for production estimation. This research developed an approach for coffee mapping and change detection using Landsat and DEM data in Central Highlands, Vietnam. The data were processed for 1995, 2005, and 2020 using random forests (RF). The mapping results, verified with reference data, showed overall accuracy and Kappa coefficient higher than 86.9% and 0.74, respectively. These findings were reaffirmed by a close relationship between the satellite-based coffee area and official statistics, with the root mean squared percentage error (RMSPE) and mean absolute percentage error (MAPE) greater than 9.9% and 7.6%, respectively. From 1995 to 2020, the newly planted coffee area increased by 135,520 ha, due to the conversion of forests to coffee plantations. Such distributions of coffee areas and decadal changes in farming activities are critically useful for policymakers to formulate successful crop planning strategies.
HCI Design Patterns for C2: A Vision for a DoD Design Reference Library (2006)

Command and Control (C2) operators require well designed human computer interfaces (HCI) to effectively perform cognitive work. However, a methodology for transforming a requirements analysis into a useful HCI design is lacking. HCI Design Patterns (HCI DP) may help bridge this "design gap". A set of reusable patterns known to support work functions could reduce the cost and risk associated with the design of future systems. HCI DP are an offshoot of architectural design patterns, used to catalog architectural solutions for recurring architectural design problems. Libraries of HCI DP are viewable online, but they commonly assist user interactions with generic system functions rather than actual C2 work activities. The Air Force and Navy are identifying HCI DP to assist the cognitive and collaborative work of C2 operations. Objectives include 1) Reverse engineering existing HCI designs and indexing them via cognitive work functions, 2) Developing a HCI prototyping environment embedding design patterns and indexing systems. A DOD-wide HCI DP library could promote a new set of HCI standards across the services. Future designs using a common set of patterns will promote interoperability between operators in different armed services collaborating on joint missions.
Organic, Cluster Assembled and Nano-Hybrid Materials Produced by Supersonic Beams: Growth and Applications to Prototype Device Development (2005)

An approach to the growth of films of π-conjugated organic materials, cluster assembled and nanohybrid materials combining supersonic free jets with a UHV deposition apparatus including surface characterization methods will be discussed. The unique control achievable with supersonic beams on initial kinetic energy, momentum and state of aggregation enables the growth of materials with controlled properties at different length scales. Results obtained with organic semiconductors and oligomers point out the crucial role of kinetic energy in growing organic crystalline films with well controlled morphologies and structures. By means of supersonic beams of clusters, nanocrystalline metal oxide films can be grown without annealing, so that grain size and morphology can be better controlled. In a co-deposition scheme these interesting features are combined in order to obtain a new class of hybrid functional materials with appealing properties for electronics, gas sensing and photovoltaic applications.
Modeling scattering effects from time-varying sea surface based on acoustic reciprocity (2017)

In marine seismic processing, the sea surface is often considered a flat mirror; hence, the effects of different weather conditions during the acquisition are largely ignored. However, studies have shown that rough sea-surface ghosts can severely damage the 4D signal, if not handled properly in data processing. To account for realistic sea-surface effects in processing, the impact of time-varying rough sea surfaces needs to be studied. We derive a method for modeling source and receiver ghosts from the time-varying rough sea surface and their interaction with subsurface reflections. This method is based on acoustic reciprocity and leads to integral equations of nonstationary wavefields. These modeling equations can also serve as a basis for investigating source and receiver deghosting methods for time-varying rough sea surfaces. Our developed modeling algorithm is validated against a frequency-domain approach for a “frozen” rough sea surface. For a moving simple sea surface, the Doppler shift produced by our method is in very good agreement with the analytical solution. Using a Pierson-Moskowitz spectrum, we derive a time-varying rough sea surface and model the receiver ghost, the source ghost, and the source-receiver ghost for the subsurface primary reflections of a heterogeneous geologic model. The results highlight that the source and receiver ghost interactions with a time-varying sea surface differently affect the subsurface reflections, and these effects can significantly impact the seismic repeatability of 4D studies.

Productivity, Energy Use Efficiency and Economics of Organic Scented Rice Cultivation in Sub-Humid Agroecosystem (2017)

The increasing demand for organic cereals especially indigenous scented rice varieties in the recent years has peaked farmers’ interest towards its organic production. However, the threat of crop loss under organic cultivation has been holding back large scale initiatives. Inhana Rational Farming (IRF) Technology has come up as a promising organic package of practice towards mitigating this drawback of organic production that too at an affordable economics. The present study was conducted to generate scientific information regarding organic scented rice cultivation (Oryza sativa var. ‘Gobindobhog’) utilizing this organic POP in terms of productivity, energy use efficiency and economics. The yield of scented rice cultivated using organic POP was found to be 18% higher than the conventionally grown ones. In terms of energy use efficiency as well, organic POP was calculated to be more efficient signifying the role of organic practice in sustainable agriculture. Net profitability of organic paddy increased up to 17% with a minimum premium price of 25%. This increased higher income opportunity from same unit of land was an added benefit apart from improved soil quality in general; under organic management.
Cell surface expression of the amino-terminal domain of A kappa alpha. Recognition of an isolated MHC antigenic structure by allospecific T cells but not alloantibodies. (1988)

To evaluate the relationship between structure and function of the alpha 1 and beta 1 domains of class II MHC molecules, a strategy has been developed whereby isolated alpha 1 or beta 1 domains can be expressed on the surface of transfected mouse L cells as a part of a hybrid class II/class I molecule. The construction and expression of a chimeric class II/class I gene encoding the first two exons of A kappa alpha linked to the C2, TM and cytoplasmic exons of H-2Dd (A kappa alpha 1/DdC2) are described. High levels of A kappa alpha 1/DdC2 protein were detected on transfected L cells with a DdC2-specific mAb. An anti-Ia xenoantiserum specifically bound to A kappa alpha 1/DdC2-transfected L cells, although 12 different mAb reactive against I-A kappa alpha and an anti-Ia kappa alloantiserum did not bind these cells. However, alloreactive Ia kappa-specific CTL lines were able specifically to lyse cells expressing the hybrid A kappa alpha 1/DdC2 molecule. This indicates that the isolated A kappa alpha 1 domain preserves some of the structure of the native molecule and demonstrates the recognition by T cells of domain-specific A alpha allodeterminants.
Up‐regulation of oligodendrocyte precursor cell αV integrin and its extracellular ligands during central nervous system remyelination (2009)

To determine the role of extracellular matrix molecules and their integrin ligands in CNS remyelination, we have examined in experimentally induced focal demyelinated lesions the expression of the two classes of integrins implicated in oligodendrocyte development and myelination: alpha6 laminin-binding integrins and alphaV integrins that bind a range of extracellular matrix proteins containing the -Arg-Gly-Asp- (RGD) recognition sequence. Only alphaV integrins were up-regulated during remyelination, being expressed on oligodendrocyte precursor cells during their recruitment into the lesion. Next, therefore, we examined the expression of extracellular matrix ligands for alphaV integrins and documented increased expression of tenascin-C, tenascin-R, fibronectin, and vitronectin. Taken together with our previous discovery of high levels of expression of another alphaV ligand, osteopontin, during remyelination in these lesions, our findings suggest that alphaV integrins make an important contribution to successful repair in the CNS.
Evaluation of Concurrent Radiation, Temozolomide and ABT-888 Treatment Followed by Maintenance Therapy with Temozolomide and ABT-888 in a Genetically Engineered Glioblastoma Mouse Model (2016)

Despite the use of ionizing radiation (IR) and temozolomide (TMZ), outcome for glioblastoma (GBM) patients remains dismal. Poly (ADP-ribose) polymerase (PARP) is important in repair pathways for IR-induced DNA damage and TMZ-induced alkylation at N7-methylguanine and N3-methyldenine. However, optimized protocols for administration of PARP inhibitors have not been delineated. In this study, the PARP inhibitor ABT-888 was evaluated in combination with and compared to current standard-of-care in a genetically engineered mouse GBM model. Results demonstrated that concomitant TMZ/IR/ABT-888 with adjuvant TMZ/ABT-888 was more effective in inducing apoptosis and reducing proliferation with significant tumor growth delay and improved overall survival over concomitant TMZ/IR with adjuvant TMZ. Diffusion-weighted MRI, an early translatable response biomarker detected changes in tumors reflecting response at 1 day post TMZ/IR/ABT-888 treatment. This study provides strong scientific rationale for the development of an optimized dosing regimen for a PARP inhibitor with TMZ/IR for upfront treatment of GBM.

A tutorial on complex seismic trace analysis (2007)

Abstract Complex seismic trace analysis treats a seismic trace as the product of two independent and separable functions: instantaneous amplitude and cosine of the instantaneous phase. At any given time, instantaneous amplitude is the maximum value the seismic trace can attain under a constant phase rotation, and instantaneous phase is the phase angle required to rotate the trace to the maximum. Defining these two attributes in this way permits complex seismic trace analysis to be founded without reference to the complex trace. All other complex seismic trace attributes derive from amplitude and phase through differentiation, averaging, combination, or transformation. The chief derived attributes are frequency, relative amplitude change, wavelength, dip, and azimuth. At any point on a seismic trace, the instantaneous attributes describe a sinusoid that locally matches the trace. Most instantaneous attributes are improved through filtering or weighted averaging. The phase wavenumber vector provides a convenient basis for quantifying 3D seismic properties such as reflection parallelism.
