Evaluation of Special Surface Treatment Aged Using UV, Phase I (2011)

Research was undertaken to evaluate the effectiveness of Tensar’s specialty polymer cement slurry (coating) in reducing aging of asphalt binders and mixtures. The study was also aimed at evaluating the effect of this material on performance characteristics of asphalt binder and asphalt concrete through laboratory investigation. The plan required preparation and testing materials at different aging levels. The materials included the asphalt binders and mixtures prepared with and without a coating level of Tensar’s coating. Aging was achieved through rolling thin film oven (RTFO), pressure aging vessel (PAV), and Ultraviolet (UV) chamber. Aging in the UV chamber was conducted for 3 days, 7 days, 14 days, and 28 days. Testing for the binder included dynamic shear rheometer (DSR), bending beam rheometer (BBR), and Fourier transform Infrared spectroscopy (FTIR). Mixture testing was conducted using the third scale model mobile load simulator (MMLS3).

Our results stress the importance of FISH on uncultured amniotic fluid cells to supplement routine cytogenetics, especially in cases with abnormal ultrasound findings.
Prototyping a high-performance low-cost solid-state disk (2011)

We present a design for a high-performance low-cost solid-state disk (SSD). Ignoring garbage-collection costs, our SSD performs only 1 + ε physical accesses to NAND flash pages for every request of a page-size block by the host, for some small ε. This is true for all access patterns, including random writes, which are usually slow on low-cost SSDs. Garbage collection in all SSDs is determined primarily by how full the SSD is, and its cost is similar in most SSDs. The unique feature in our design is that it achieves high performance even with when the SSD contains only a small amount of RAM. In most SSD designs, this would imply low performance; in ours, it does not. A small RAM lowers the cost of an SSD with a given flash array. Our design achieves high performance with a small RAM using two innovative ideas. One is the use of a clever mapping data structure. The second is a host-assisted hinting mechanism that uses RAM on the host to compensate for the small amount of RAM within the SSD. This mechanism is implemented as an enhanced SCSI driver (kernel module). Our prototyping methodology is also a significant contribution. We simulate the SSD in software, using files to represent the flash array, but the resulting prototype is a working SCSI device that file systems can be mounted on.
A study of heterofertilization in diverse lines of maize (1984)

In maize, extensive studies of heterofertilizatlon in various genetic backgrounds for both pollen and ear parents reveal that heterofertilization percentages vary within a narrow range. The highest percentage observed for a given cross was 5 percent. Most stocks had less than 1 percent heterofertilizatlon. No stock was observed with a percentage as high as the 25 percent reported in previous work on this phenomenon. Evidence is presented that both male and female factors can influence the percentage of heterofertilization. Stronger female than male effects, however, were observed. There is an indication that some of the factors affecting the frequency of heterofertilization have a genetic base, although no single gene effects could be demonstrated.
Transmission of 250 Gb/s Net Rate per Lambda using IMDD PAM-6 and PAM-8 (2020)

We experimentally demonstrate the transmission of a net rate of 250 Gb/s/lambda using PAM-6 and PAM-8 IMDD over 1-km single-mode fiber using commercially available components. A power sensitivity of -6dBm (-5dBm) is achievable for PAM-6 (PAM-8).
Graphitic carbon nitride nanosheets as a multifunctional nanoplatform for photochemical internalization-enhanced photodynamic therapy (2018)

Photodynamic therapy (PDT) has been widely used as a noninvasive and moderate technique in precision cancer therapy by destroying cancer cells via light-induced reactive oxygen species (ROS). However, the overproduction of heat shock protein 70 (HSP70) induced by ROS will contribute to the cell survival under harsh conditions, finally leading to decreased PDT efficiency. To overcome this issue, herein, for the first time, we have prepared an HSP70 inhibitor (2-phenylethynesulfonamide (PES))-loaded graphitic carbon nitride nanosheet (GCNS) as a multifunctional nanoplatform (GCNS-PES) for enhanced PDT. By taking advantage of commendable PDT efficiency, strong blue fluorescence, satisfactory drug loading capacity and good water dispersity, the GCNS can simultaneously serve as a photosensitizer, an imaging agent and a drug carrier. Moreover, when the nanoplatform is restricted in the endo/lysosome vesicles through endocytosis, the GCNS can generate ROS effectively under visible light irradiation to promote the lipid peroxidation of endo/lysosomal membranes and accelerate the liberation of GCNS and PES into the cytoplasm. Finally, the tolerance of cancer cells to ROS is decreased by PES-induced HSP70 inactivation, and therefore the efficiency of PDT is significantly enhanced. As a result, GCNS-PES can serve as a promising therapeutic nanoplatform for photo-controlled cancer therapy.
Hyperspectral Imaging of Structure and Composition in Atomically Thin Heterostructures (2013)

Precise vertical stacking and lateral stitching of two-dimensional (2D) materials, such as graphene and hexagonal boron nitride (h-BN), can be used to create ultrathin heterostructures with complex functionalities, but this diversity of behaviors also makes these new materials difficult to characterize. We report a DUV-vis-NIR hyperspectral microscope that provides imaging and spectroscopy at energies of up to 6.2 eV, allowing comprehensive, all-optical mapping of chemical composition in graphene/h-BN lateral heterojunctions and interlayer rotations in twisted bilayer graphene (tBLG). With the addition of transmission electron microscopy, we obtain quantitative structure-property relationships, confirming the formation of interfaces in graphene/h-BN lateral heterojunctions that are abrupt on a micrometer scale, and a one-to-one relationship between twist angle and interlayer optical resonances in tBLG. Furthermore, we perform similar hyperspectral imaging of samples that are supported on a nontransparent silicon/SiO2 substrate, enabling facile fabrication of atomically thin heterostructure devices with known composition and structure.
Polymers for electrochemical devices (1997)

Abstract Polymeric materials are already present in electrochemical storage devices such as batteries and PEM fuel cells. The polymer is an electro‐active material in lithium polymer batteries. Several network based polymer electrolytes provide thermal, mechanical and redox stabilities, while insuring a high conductivity level. Linear unsaturated polyether precursors may be obtained either by step‐growth polymerization from oligomeric polyethers, or by ring‐opening polymerization from oxirane mixtures. Some prototype performances, performed on a 10 Wh lithium polymer cell, are presented and discussed.
Preparation and characterization of interpenetrating hydrogel for colon drug delivery (2014)

This thesis work is based on preparation and characterization of Interpenetrating (IPN) hydrogels of poly (HEMA) with polysaccharides (xanthan gum or isabgol). IPN hydrogels were prepared by cross-linking the HEMA in the presence of varying concentration of xanthan gum or isabgol. The concentrations of xanthan gum used for this purpose were 0.1% (w/v), 0.3% (w/v),0.5% (w/v) and 0.7% (w/v) whereas the concentrations of isabgol selected were 1% (w/v), 2% (w/v), 3% (w/v) and 4% (w/v). The HEMA and the polysaccharides either xanthan gum or isabgol were mixed in the proportion of 30:70 (w/w) before being croslinked using APS and TEMED. The IPN hydrogels were characterized by swelling tests at Ph 1.2, pH 7 and Ph 9.Physical properties were assessed by XRD and FTIR. Suitability of its application as colon drug delivery system (CDDS) was assessed by incorporating curcumin for in-vitro drug release kinetics assay in the simulated condition of gastrointestinal system. The IPN hydrogels were found to swell maximal at pH 7 and the rate of drug release was found to be highest at pH 6.8 indicating its potential application as CDDS.
MIXING-MODEL SENSITIVITY TO INPUT PARAMETER VARIATION (2017)

Amagat and Dalton mixing-models were analyzed to compare their thermodynamic prediction of shock states. Numerical simulations utilized the Sandra National Laboratories (SNL) shock hydrodynamic code CTH Simulations modeled the University of New Mexico (UNM) shock tube laboratory experimental series shocking a 1:1 molar mixture of helium (He) and sulfur hexafluoride (SF6). Five input parameters were varied for sensitivity analysis: driver section pressure; driver section density; test section pressure; test section density; and mixture ratio (mole fraction). We show via incremental Latin hypercube sampling (LHS) analysis that significant differences exist between Amagat and Dalton mixing-model predictions. The differences observed in predicted shock speeds, temperatures, and pressures grow more pronounced with higher shock speeds.

Comparison of Human Selenoprotein P Determinants in Serum between Our Original Methods and Commercially Available Kits (2018)

Selenoprotein P (SeP) is a selenium (Se)-rich extracellular protein. SeP is identified as a hepatokine, causing insulin resistance in type 2 diabetes. Thus, the measurement of SeP in serum has received much attention, and several enzyme-linked immunosorbent assay (ELISA) kits for SeP determination are now commercially available. In the present study, we determined the serum SeP levels by our original ELISA and sol particle homogeneous immunoassay (SPIA) methods and also by commercially available kits, and these determinants were compared. We found a kit-dependent correlation of the determinants with our methods. These results suggest that the selection of kit is critical for comparison with our previous reports and for discussing the relationship between the serum SeP levels and disease condition.
Quantitative evaluation method for detectability of voids using ultrasound (2017)

We have developed a new method to quantitatively evaluate the detectability for voids in bonded wafers by using ultrasonic inspection. The test sample for evaluation consists of bonded two Si wafers and has artificial voids between the wafers. The depths of these artificial voids are 5, 10, 20, and 170 nm. In this study, the evaluation was made by obtaining the images of artificial voids by using transducers with various nominal frequencies and focal lengths. It was found that even the voids with a depth of 5 nm or more can be detected and that the minimum dimension of detectable void is independent of the void depth. Better resolution and detectability of small voids were achieved by transducers with higher frequency. Furthermore, it is demonstrated that a transducer having an appropriate focal length should be selected, in accordance with the thickness of the bonded wafer.
Optimum space-time processors with dispersive interference-unified analysis and required filter span (2003)

We consider optimum space-time equalizers with unknown dispersive interference, consisting of a linear equalizer that both spatially and temporally whitens the interference and noise, followed by a decision-feedback equalizer (DFE) or maximum-likelihood sequence estimator (MLSE). We first present a unified analysis of the optimum space-time equalizer, and then show that, for typical fading channels with a given signal-to-noise ratio (SNR), near-optimum performance can be achieved with a finite-length equalizer. Expressions are given for the required filter span as a function of the dispersion length, number of cochannel interferers, number of antennas, and SNR, which are useful in the design of practical, near-optimum space-time equalizers.
Effects of homogenization of different pressures on the creaming of UHT milk during storage. (2009)

Three groups of Ultra Head Treated(UHT) milk homogenized under the pressures of 10,20,and 30MP were stored at 25 ℃ for 6 months(180 days).Particle size was analyzed after homogenisation.Fat contents of different parts of the containers,and creaming were de-tected during the storage.Smaller fat globle size and less creaming were observed in the milk treated by higher pressure.The stability of UHT milk was improved remarkably by higher pressrure of homogenization.
Energy-Efficient Privacy Protection for Smart Home Environments Using Behavioral Semantics (2014)

Research on smart environments saturated with ubiquitous computing devices is rapidly advancing while raising serious privacy issues. According to recent studies, privacy concerns significantly hinder widespread adoption of smart home technologies. Previous work has shown that it is possible to infer the activities of daily living within environments equipped with wireless sensors by monitoring radio fingerprints and traffic patterns. Since data encryption cannot prevent privacy invasions exploiting transmission pattern analysis and statistical inference, various methods based on fake data generation for concealing traffic patterns have been studied. In this paper, we describe an energy-efficient, light-weight, low-latency algorithm for creating dummy activities that are semantically similar to the observed phenomena. By using these cloaking activities, the amount of fake data transmissions can be flexibly controlled to support a trade-off between energy efficiency and privacy protection. According to the experiments using real data collected from a smart home environment, our proposed method can extend the lifetime of the network by more than 2× compared to the previous methods in the literature. Furthermore, the activity cloaking method supports low latency transmission of real data while also significantly reducing the accuracy of the wireless snooping attacks.
Formation and Development of Strong Cube Recrystallization Texture in an Aluminium of Commercial Purity (2011)

The goal of the present study inspired by previous works on high purity aluminiun was to manufacture aluminium sheets of commercial purity, grade 1050, with a strong cube texture. In this preliminary work on AA1050, sheets which cube volume fraction reaches 65% have been manufactured. Parameters controlling cube orientation development are mainly the solute dragging due to impurities in solid solution and the stored deformation energy. Besides the 85% cold rolling (CR), two extra annealings and a slight cold rolling are introduced in the processing route to increase the cube volume fraction. The cube orientation, whose substructure is equiaxed, is important for its recovery. It develops thanks to the difference of stored energy relative to that of its first neighbors; the slight cold rolling enhances growth of these cube grains.
A solar-powered, milligram prototype robot from a three-chip process (2003)

Commercial CMOS electronics and two in-house processes have been combined to establish a framework for making hybridized, milligram mobile robots. To demonstrate the capabilities of this framework, an 8.6 mm long, 10 mg, solar-powered prototype robot has been built. Dragging its tail end, the robot has demonstrated autonomous movement under its own weight and power, shuffling to the side a few millimeters and lifting its front end as much as 300 μm off the surface. 
A simple 5-mask process, the Iolanthe process, was devised for the robot's frame, inchworm motors, and legs. The Iolanthe process combined bulk SOI micromachining with polysilicon surface micromachining to achieve high-force in-plane electrostatic motors with compliant out-of-plane structures. The enabling step of the process was planarization of the SOI device layer using thick glass planarization technology. Out-of-plane leg motion was demonstrated using electrostatic inchworm motors with polysilicon pin hinges. In addition to the one-DOF legs for the robot, a two-DOF leg and a bidirectional inchworm motor were also fabricated and tested. Inchworm motors demonstrated 400 μm of travel at speeds up to 6.8 mm/s. The two-DOF leg demonstrated angular deflections over 90°, and the one-DOF leg output forces up to 60 μN. 
In the second process, high-voltage solar cell arrays were created to drive the electrostatic actuators of the inchworm motors. In order to generate the high voltages, individual solar cells were electrically isolated with isolation trenches on the SOI device layer. Solar cell arrays as small as 0.6 mm2 generated over 30 V. NMOS and PMOS transistors with breakdown voltages ranging from 42 V to 100 V were also integrated into the process. With these devices, a 50 V solar-powered buffer was demonstrated in an area of 3.6 × 1.8 mm2. 
The third and final chip of the robot was fabricated in a commercial CMOS foundry. The chip provided the logic signals to drive the legs in an open-loop walking gait.

Solvent Hold Tank Sample Results for MCU-16-934-935-936: June 2016 Monthly Sample (2016)

Savannah River National Laboratory (SRNL) received one set of Solvent Hold Tank (SHT) samples (MCU-16-934-935-936), pulled on 07/01/2016 for analysis. The samples were combined and analyzed for composition. Analysis of the composite sample MCU-16-934-935-936 indicated the Isopar™L concentration is above its nominal level (101%). The modifier (CS-7SB) and the TiDG concentrations are 8% and 29 % below their nominal concentrations. This analysis confirms the solvent may require the addition of TiDG, and possibly of modifier. Based on the current monthly sample, the levels of TiDG, Isopar™L, MaxCalix, and modifier are sufficient for continuing operation but are expected to decrease with time. Periodic characterization and trimming additions to the solvent are recommended. No impurities above the 1000 ppm level were found in this solvent by the Semi-Volatile Organic Analysis (SVOA). No impurities were observed in the Hydrogen Nuclear Magnetic Resonance (HNMR). However, up to 21.1 ± 4 micrograms of mercury per gram of solvent (or 17.5 μg/mL) was detected in this sample (as determined by the XRF method of undigested sample). The current gamma level (1.41E5 dpm/mL) confirmed that the gamma concentration has returned to previous levels (as observed in the late 2015 samples) where the process operated normally and as expected.
Application of Integrated Drug Screening/Kinome Analysis to Identify Inhibitors of Gemcitabine-Resistant Pancreatic Cancer Cell Growth (2018)

Continuous exposure of a pancreatic cancer cell line MIA PaCa-2 (Mia<sup>S</sup>) to gemcitabine resulted in the formation of a gemcitabine-resistant subline (Mia<sup>R</sup>). In an effort to discover kinase inhibitors that inhibited Mia<sup>R</sup> growth, Mia<sup>R</sup> cells were exposed to kinase inhibitors (PKIS-1 library) in a 384-well screening format. Three compounds (UNC10112721A, UNC10112652A, and UNC10112793A) were identified that inhibited the growth of Mia<sup>R</sup> cells by more than 50% (at 50 nM). Two compounds (UNC10112721A and UNC10112652A) were classified as cyclin-dependent kinase (CDK) inhibitors, whereas UNC10112793A was reported to be a PLK inhibitor. Dose-response experiments supported the efficacy of these compounds to inhibit growth and increase apoptosis in 2D cultures of these cells. However, only UNC10112721A significantly inhibited the growth of 3D spheroids composed of Mia<sup>R</sup> cells and GFP-tagged cancer-associated fibroblasts. Multiplexed inhibitor bead (MIB)-mass spectrometry (MS) kinome competition experiments identified CDK9, CLK1-4, DYRK1A, and CSNK1 as major kinase targets for UNC10112721A in Mia<sup>R</sup> cells. Another CDK9 inhibitor (CDK-IN-2) replicated the growth inhibitory effects of UNC10112721A, whereas inhibitors against the CLK, DYRK, or CSNK1 kinases had no effect. In summary, these studies describe a coordinated approach to discover novel kinase inhibitors, evaluate their efficacy in 3D models, and define their specificity against the kinome.
Faculty Opinions recommendation of Binding of the Treslin-MTBP Complex to Specific Regions of the Human Genome Promotes the Initiation of DNA Replication. (2021)

The processes that control where higher eukaryotic cells initiate DNA replication throughout the genome are not understood clearly. In metazoans, the Treslin-MTBP complex mediates critical final steps in formation of the activated replicative helicase prior to initiation of replication. Here, we map the genome-wide distribution of the MTBP subunit of this complex in human cells. Our results indicate that MTBP binds to at least 30,000 sites in the genome. A majority of these sites reside in regions of open chromatin that contain transcriptional-regulatory elements (e.g., promoters, enhancers, and super-enhancers), which are known to be preferred areas for initiation of replication. Furthermore, many binding sites encompass two genomic features: a nucleosome-free DNA sequence (e.g., G-quadruplex DNA or AP-1 motif) and a nucleosome bearing histone marks characteristic of open chromatin, such as H3K4me2. Taken together, these findings indicate that Treslin-MTBP associates coordinately with multiple genomic signals to promote initiation of replication.Copyright © 2020 The Author(s).

Receiver channel equalization for adaptive antennas: experimental results (1990)

The authors describe two complementary approaches for attacking the channel equalization problem within the framework of a primarily digital sidelobe canceling system. The first relies heavily on digital filtering techniques, while the second extends the SMI (sample matrix inversion) method into the realm of analog adaptive cancellation. The latter approach eases some of the digital signal processing requirements imposed by the former, although not without increasing the complexity of the receiver. In demanding applications, further improvements may be realizable by combining the two basic approaches in a tandem architecture. The experimental system was designed and built with the capability to test all three methods. Its modes of operation are depicted in simplified block diagram form and are explained. Empirical results from bench tests conducted with the experimental receiver demonstrate that the proposed methods can substantially improve cancellation performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
