A new approach to designing electronic systems for operation in extreme environments: Part II - The SiGe remote electronics unit (2012)

We have presented the architecture, simulation, packaging, and over-temperature and radiation testing of a complex, 16-channel, extreme environment capable, SiGe Remote Electronics Unit containing the Remote Sensor Interface ASIC that can serve a wide variety of space-relevant needs as designed. These include future missions to the Moon and Mars, with the additional potential to operate in other hostile environments, including lunar craters and around the Jovian moon, Europa. We have expanded on the previous introduction of the RSI to show the validity of the chip design and performance over an almost 250 K temperature range, down to 100 K, under 100 krad TID radiation exposure, with SEL immunity and operability in a high-flux SET environment.
Multidimensional spatial and coherence imaging using single shot spectral imagers (2007)

A spectral imaging system may efficiently sense 10-100 spectral channels but the full data cube is often redundant. We propose to exploit this redundancy to computationally expand depth of field or obtain multidimensional spatial images.
Citrus Thrips (Thysanoptera: Thripidae) Pesticide Resistance in the Coachella and San Joaquin Valleys of California (1989)

Citrus thrips (Scirtothrips citri (Moulton)) resistance to dimethoate, or formetanate, or both was evaluated in 13 commercial citrus groves in the Coachella and San Joaquin Valleys of California in 1986. Dimethoate resistance was apparent at one site in the Coachella Valley (30.0-fold at the LC50) and at all San Joaquin Valley sites (21.5–90.3-fold at the LC50). Increased levels of formetanate use appeared to be correlated with increased resistance (up to 31.0-fold at the LC50) to this chemical. Intensity and frequency of dimethoate and formetanate resistance were higher and more widespread in the San Joaquin Valley than in the Coachella Valley. These results are discussed with respect to general patterns of citrus thrips resistance and their implications to resistance management.
Morphology and phase behavior of ethanol nanodrops condensed on chemically patterned surfaces (2008)

Equilibrium wetting of ethanol onto chemically patterned nanostripes has been investigated using environmental atomic force microscopy (AFM) in noncontact mode. The chemical patterns are composed of COOH-terminated "wetting" regions and CH3-terminated "nonwetting" regions. A specially designed environmental AFM chamber allowed for accurate measurements of droplet height as a function of the temperature offset between the substrate and a macroscopic ethanol reservoir. At saturation, the height dependence scales with droplet width according to w1/2, in excellent agreement with the augmented Young equation (AYE) modeled with dispersive, nonretarded surface potentials. At small under- and oversaturations, the AYE model accurately fits the data if an effective DeltaT is used as a fitting parameter. There is a systematic difference between the measured DeltaT and the values extracted from the fits to the data. In addition to static measurements, we present time-resolved measurements of the droplet height which enable the study of condensation-evaporation dynamics of nanometer-scale drops.
Automation of avatar behavior (2014)

The graphical virtual worlds that sprang up in the mid-90s were truly inspiring. Finally the cyberspace that was promised to us by science-fiction was taking shape in front of our eyes. We could finally shed our real-life carcasses and enter a world of endless possibilities in shiny new digital bodies. The avatars we would embody would allow us to share this experience with others, just as if they were right there with us face-to-face.
Multi-Agent Planning for Persistent Missions with Automated Battery Management (2011)

This paper introduces and demonstrates a full hardware testbed for research in long-duration missions for multiple, autonomous agents. Speci cally, we describe an automated battery management platform designed to service multiple quadrotor agents in the MIT RAVEN and Boeing VSTL ight environments. The changing/charging station allows the quadrotor’s spent battery to be quickly swapped for a fresh one without requiring it to power down or wait for recharge a signi cant bene t in persistent and/or time-critical missions. We focus on a multi-agent persistent search and track scenario and construct both centralized and decentralized MDP-based mission planners. We further show that for the three agent case, decentralized planners (one for each agent) o er a 99% reduction in computation time and only a relatively small (10%) degradation in overall mission performance when compared to the centralized approach over a long-term simulated mission.
IL-7R is essential for leukemia-initiating cell activity of T-cell acute lymphoblastic leukemia (2019)

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy resulting from the dysregulation of signaling pathways that control intrathymic T-cell development. Relapse rates are still significant, and prognosis is particularly bleak for relapsed patients. Therefore, development of novel therapies specifically targeting pathways controlling leukemia-initiating cell (LIC) activity is mandatory for fighting refractory T-ALL. The interleukin-7 receptor (IL-7R) is a crucial T-cell developmental pathway that is commonly expressed in T-ALL and has been implicated in leukemia progression; however, the significance of IL-7R/IL-7 signaling in T-ALL pathogenesis and its contribution to disease relapse remain unknown. To directly explore whether IL-7R targeting may be therapeutically efficient against T-ALL relapse, we focused on a known Notch1-induced T-ALL model, because a majority of T-ALL patients harbor activating mutations in NOTCH1, which is a transcriptional regulator of IL-7R expression. Using loss-of-function approaches, we show that Il7r-deficient, but not wild-type, mouse hematopoietic progenitors transduced with constitutively active Notch1 failed to generate leukemia upon transplantation into immunodeficient mice, thus providing formal evidence that IL-7R function is essential for Notch1-induced T-cell leukemogenesis. Moreover, we demonstrate that IL-7R expression is an early functional biomarker of T-ALL cells with LIC potential and report that impaired IL-7R signaling hampers engraftment and progression of patient-derived T-ALL xenografts. Notably, we show that IL-7R-dependent LIC activity and leukemia progression can be extended to human B-cell acute lymphoblastic leukemia (B-ALL). These results have important therapeutic implications, highlighting the relevance that targeting normal IL-7R signaling may have in future therapeutic interventions, particularly for preventing T-ALL (and B-ALL) relapse.
Topology, connectivity and electronic structure of C and B cages and the corresponding nanotubes (2003)

After a brief discussion of the structural trends which appear with increasing number of atoms in B cages, a one-to one correspondence between the connectivity of B cages and C cage structures will be proposed. The electronic level spectra of both systems from Hartree-Fock calculations is given and discussed. The relation of curvature introduced into an originally planar graphitic fragment to pentagonal 'defects' such as are present in buckminsterfullerene is also briefly treated. A study of the structure and electronic properties of B nanotubes will then be introduced. We start by presenting a solution of the free-electron network approach for a 'model boron' planar lattice with local coordination number 6. In particular the dispersion relation E(k) for the pi-electron bands, together with the corresponding electronic Density Of States (DOS), will be exhibited. This is then used within the zone folding scheme to obtain information about the electronic DOS of different nanotubes obtained by folding this model boron sheet. To obtain the self-consistent potential in which the valence electrons move in a nanotube, 'the March model' in its original form was invoked and results are reported for a carbon nanotube. Finally, heterostructures, such as BN cages and fluorinated buckminsterfullerene, will be briefly treated, the new feature here being electronegativity difference.
Segmentation of 3D RF echocardiography using a joint spatio-temporal predictor and signal intensity model (2011)

We present an approach for left ventricular segmentation of radio-frequency (RF) ultrasound sequences. Our method employs an independent identically distributed (iid) spatial model for RF voxel intensity and a conditional model relating a subsequent frame in the image sequence to the frame being segmented by means of a linear predictor that exploits spatio-temporal coherence in the data. The conditional model overcomes segmentation problems due to image inhomogeneity issues, while the spatial model overcomes a tendency of the conditional model to underestimate the blood pool. The method is validated by comparison with manual tracings, segmentations performed using Chan-Vese level sets, and by segmentations leveraging only the linear predictor.
A Hierarchical Electromagnetic-Circuit Technique for Statistical Analysis of RF Circuits in the Spectral Domain (2009)

Spectral domain statistical analysis of RF circuits, combining a circuit simulator, which models the circuit part and a full-wave field solver, which models the passive elements, is presented in this paper. This paper first illustrates the importance of the knowledge of correlation information in accurately modeling the probability density functions (PDFs) of eventual objective functions using a simple transmission line paradigm. Next, this paper looks at the statistical study of on-chip RF passives using the spiral inductor as an example. It is shown that larger process variations necessitate modeling by means of a quadratic response surface to preserve accuracy. This results in nonindependent non-Gaussian nonclosed-form PDFs for the equivalent-circuit parameters of the passives. This paper then proposes a hierarchical technique to perform statistical analysis of RF circuits based on <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">y</i> -parameter representation for the circuit and the passive element parts. The proposed technique obviates the need for optimization steps to derive the equivalent-circuit parameters for the electromagnetic objects and the need to compute the correlation matrix between the circuit equivalent elements, while maintaining accuracy. The proposed approach is illustrated for the statistical analysis of an RF amplifier and its differential version operating at 15.78 GHz. PDFs of various quantities of interest are derived and yield measures are computed.
In vitro Study of Starling’s Hypothesis in a Cultured Monolayer of Bovine Aortic Endothelial Cells (2003)

Starling's hypothesis that fluid movement across the microvascular wall is determined by the transmural differences in hydrostatic and osmotic pressures was tested using an in vitro model comprised of bovine aortic endothelial cells grown on a porous support. In all experiments, a 1% bovine serum albumin (BSA) solution was maintained in the abluminal reservoir and the luminal reservoir contained either a 1 or a 5.5% BSA solution. The global osmotic pressure difference across the endothelial layers was thus either 0 or 20.3 cm H2O. When the luminal concentration of BSA was changed from 1 to 5.5% at a hydrostatic pressure differential of 5, 10 or 20 cm H2O, no reverse flow (in the reabsorption direction) was observed even though the hydrostatic pressure differential was far below the global osmotic pressure differential. In another case, the hydrostatic pressure differential was dropped quickly from 20 to 5 cm H2O, while a constant osmotic pressure differential was maintained by 5.5% BSA in the luminal reservoir. A strong transient reabsorption flow was observed over a 30-second period which diminished to undetectable levels within 2.5 min; then a sustained steady-state filtration flow was observed after 20 min. These in vitro experiments support other studies in capillaries showing transient reabsorption that decays to steady-state filtration at longer times.
Cellulose Microfibrils/Nanofibrils (CMNF) Produced from Banana (<i>Musa acuminata</i>) Pseudo-Stem Wastes: Isolation and Characterization (2016)

Banana pseudostems waste is abundantly available as agro-waste and has been used in different applications. In this work, the isolation of CMNF from the pseudostems of banana plant were explored. The dried stems from the species Musa acuminata were first cleaned by soxhlet extraction, alkali treatment and bleaching. Segal method will be employed to analyze data from XRD to determine crystallinity of the CMNF. Morphology of the CMNF will be determined using FESEM. Characterizations of treated and untreated samples were compared. The comparison between those treated and untreated samples giving the information about crystallite size, crystallinity and surface morphology for each treatment.

THM formation potential (THMFP) at different stations of the river and the contribution from point and nonpoint sources within the river basin were determined. Contributions from both wet and dry precipitations were also evaluated. UV 260, DOC and THMFP were relatively high in water samples collected from stations where inflows of industrial effluents, domestic wastewater and agricultural drains were in the vicinity. Low values were noted at stations near wooded areas. However significant increase in UV 260, DOC and THMFP were observed in the presence of stormwater runoffs which is attributed to water soluble organic substances extracted from forest litter and top soil. The results indicate that the THM precursors in Kurose River could be attributed mainly to industrial effluents, domestic wastewater and agricultural drains. In case of rain, stormwater runoffs contributed significant amounts of THM precursors to the river.

High refractive index in wurtzite GaP measured from Fabry-Pérot resonances (2016)

We investigate the optical emission of wurtzite GaP/Al0.4Ga0.6P core/shell nanowires (NWs) transferred to a SiOx substrate to demonstrate a high degree of waveguiding of the emitted photoluminescence (PL) signal. By analysing the Fabry-Pérot mode spacing in combination with calculations of the guided modes in the NWs, we calculate a very high refractive index of bulk WZ GaP of 4.2 at a wavelength of 600 nm. The measured quality factors up to 600 indicate the excellent optical quality of the nanowire resonator.
Extensive Limb Swelling after Immunization: Reports to the Vaccine Adverse Event Reporting System (2003)

Extensive limb swelling (ELS) has been reported after vaccination with a limited number of vaccine types. We sought to describe vaccine types involved in and the clinical characteristics of ELS cases reported to the Vaccine Adverse Event Reporting System (VAERS). A case of ELS was defined as any report of edema extending at least to the elbow or knee of a vaccinated extremity. Four hundred ninety-seven cases were identified, with some describing swelling from the shoulder to the hand or the hip to the foot. Patient age ranged from 0.1 to 91 years. The proportion of reports of ELS associated with a given vaccine, among all VAERS reports received for that vaccine, varied substantially among vaccines. Most reactions began within 1 day after vaccination and involved other signs of inflammation. Postvaccination ELS can involve both the proximal and distal segments of the extremity, affects all age groups, and occurs after vaccination with a broad range of vaccines.
The Equilibrium Concept—An Extended Approach to Assess Long-Term Radionuclide Release from Repositories (1991)

AbstractThe release of radionuclides from a waste form into an aqueous phase is often assessed using a source term that considers diffusion and/or congruent matrix dissolution as the rate-determining release mechanisms. As an alternative approach, an equilibrium concept is proposed here that can be applied under the condition that there is no appreciable exchange of fluid with the environment of the waste package / form after the water inflow into the near field for a long time. In this case, all reactions that may give rise to radionuclide release will be completed after a certain time and stable final conditions will be established, in which, for each radionuclide, chemical equilibria exist between the dissolved phase and the various coexisting solid phases. Thereafter, a release of radionuclides from the near field is possible only by escape of the aqueous phase into the environment.Release rate predictions on the basis of this concept are of particular interest for the long-lived radionuclides, especially the actinides. Current efforts are aimed at predicting equilibrium concentrations both in theoretical computations and in experimental measurements.Some results available from corrosion studies on cemented waste forms in salt brine are presented. For specimens doped with cesium, strontium, plutonium, or americium these results show that for each radionuclide a partition equilibrium exists between the corrosion products of cement and the surrounding salt brine, which keeps the concentration in solution at a low level.
Tumorigenic transformation induced by a specific fragment of DNA from herpes simplex virus type 2. (1980)

Transfection of Syrian hamster embryo cells with limit digests of Bgl II-, Hpa I-, or Bgl II/Hpa I-cleaved DNA from herpes simplex virus type 2 (strain S-1) but not with salmon sperm DNA resulted in the appearance of refractile, morphologically altered cells at a frequency of 10(-5)/0.005 microgram of viral DNA within two to four passages. Transformed lines manifested reduced serum requirement and anchorage-independent growth and were tumorigenic in newborn hamsters. They expressed ICP10, a viral protein immunologically identical to the cervical-tumor-associated AG-4 antigen. Transforming activity was localized in the 16.5 x 10(6)-dalton Bgl II/Hpa I double-digest fragment CDs-1, which exhibited sequence homology to the Bgl II/Hpa I fragment CD of DNA from herpes simplex virus type 2 strain 333, mapping between coordinates 0.43 and 0.58 on the physical map of strain 333 DNA. This fragment, CD333, was also shown to induce neoplastic transformation.

Selective inhibition of the cell cycle of cultured human diploid fibroblasts by aminonucleoside of puromycin (1973)

Abstract Aminonucleoside (AMS) inhibited the cell cycle of human lung fibroblasts at a point in G1 phase and at another point in G2 phase. Even when this inhibition was fully established, DNA synthesis and mitosis which were in progress proceeded normally. Inhibition of RNA synthesis in the cultures preceded the effects on DNA synthesis and mitosis, but inhibition of protein synthesis could not be detected. These points of potential inhibition do not exist in the cell cycle of HeLa cell, or are not affected by aminonucleoside. Here inhibition of cell proliferation by AMS was less marked, and when inhibition eventually occurred it was not specific for any point of the cell cycle. The rate of entry of the inhibitor was similar in both types of cell.
