Non-isothermal Crystallization Behaviors of HDPE/MWCNT Nanocomposites (2011)

Thermal properties and non‐isothermal crystallization kinetics of polyolefin nanocomposites (high‐density polyethylene/multi‐walled carbon nanotubes) were characterized by differential scanning calorimetry and thermogravimetric analysis. In situ metallocence polymerization was used to prepare nanocomposites of multi‐walled carbon nanotubes (MWCNTs) and high‐density polyethylene (HDPE). This polymerization method consists of attaching a metallocene catalyst complex onto the surface of the MWCNTs followed by surface‐initiated polymerization to generate polymer brushes on the surface. A kinetic equation for the non‐isothermal crystallization was employed to analyze the crystallization characteristics of the nanocomposites. The Avramic exponent, n, can be reasonably well determined from the non‐isothermal crystallization exotherm. The polarized optical microscopy showed that neat polyethylene possessed a well developed spherulite morphology: whereas, the nanocomposites displayed elongated entities that subsequently developed as bundle‐like entities. Non‐isothermal analysis implicitly provides clues about the morphological development history and HDPE molecular ordering around the carbon nanotubes.

Open-Cell PolyHIPES from Polymerizable Eutectics: Tunable Morphology, Surface Modification, and Thermoresponsive Swelling Behavior (2022)

We report the preparation of thermoresponsive macroporous polymer monoliths via high internal phase emulsions (HIPEs) where a polymerizable nonionic deep eutectic solvent served as the continuous phase. Mixtures of N-isopropylacrylamide (NIPAM) and acrylamide (AAm) in various mole ratios formed low melting point liquids that we term “polymerizable eutectics”. In the presence of the nonionic surfactant Pluronic F127, stable oil-in-eutectic HIPEs are formed with hexadecane as the dispersed phase (80% v/v) and a continuous phase of the eutectic and a small amount of water. When the eutectic phase contained an initiator, RAFT chain transfer agent, and cross-linker, heating led to controlled polymerization and formation of a polyHIPE. The resulting monoliths had an interconnected porous network structure, significantly different to the equivalent structures produced from oil-in-water HIPEs, which exhibited a closed-cell morphology. The viscosity of the polymerizable eutectic and surfactant loading enabled the morphology, degree of openness, and mechanical properties of the polyHIPE to be readily tuned. When immersed in water, the monoliths exhibited temperature-dependent absorption of water due to the presence of NIPAM within the copolymer framework. Further, the inclusion of a RAFT chain transfer agent enabled subsequent surface polymerization from the polyHIPE to be realized, such that mechanical properties or surface wettability of the monolith could be varied while preserving the porous morphology. The tunable surface chemistry, porous structure, and mechanical properties of these monoliths present unique opportunities for applications as adsorbents, catalytic scaffolds, separation media, and so on.
Interaction between intrinsic knee mechanics and the knee extensor mechanism (1987)

The ability of the quadriceps muscles to extend the knee was studied relative to the intrinsic mechanical features of the knee joint. The quadriceps mechanical efficiency changed by nearly 50% between 0 and 90 degrees of knee flexion. The peak efficiency occurred at approximately 20 degrees of knee flexion. The mechanical efficiency of the quadriceps was dependent on the movement of the net anteroposterior (AP) tibiofemoral contact center of pressure, the change in patellar ligament angle, and the change in the quadriceps-to-ligament force transfer ratio. The average net AP tibiofemoral contact center of pressure moved posteriorly on the tibial plateau as the knee flexed from 0 to 90 degrees. The excision of both cruciate ligaments reversed the posteriorly directed movement of the net AP tibiofemoral contact center of pressure at flexion angles from 60 to 90 degrees, resulting in a reduction in extension moment.
X-ray diffuse-scattering study of interfacial morphology and conformal roughness in metallic multilayers (1995)

The nature of the interfacial roughness in ${\mathrm{Ni}}_{0.81}$${\mathrm{Fe}}_{0.19}$/Au multilayers was studied using x-ray diffuse scattering. Using an image-plate detector this scattering could be observed to an extended momentum transfer. The roughness exponent and the cutoff length of the interfacial height-height self-correlation function could thereby be determined using a model of conformal roughness, for which the interfaces are smooth within the cutoff length. We also show that while the roughness is not conformal for short length scales, a transition to conformal behavior occurs from \ensuremath{\sim}25 to 100 \AA{}.
Cancer patients’ and healthcare providers’ perceptions about supportive and integrative oncology services. (2018)

100 Background: Supportive and integrative oncology services help to improve quality of life for cancer patients. This study characterizes and compares the perceptions of these services among cancer patients and healthcare providers. Methods: A cross-sectional survey was administered to Seidman Cancer Center (SCC) providers online in Spring 2018 and to SCC patients in waiting rooms March - July 2018. The survey asked about familiarity, perceived importance, frequency of use, accessibility and barriers of 19 supportive and integrative oncology services using a 5 point Likert scale. Data analysis included the Chi-square test and Spearman’s rank correlation. Results: A total of 585 surveys were obtained (421 patients and 164 healthcare providers). Patients were generally &gt; 60 (58.2%), female (57.4%), Caucasian (64.2%) with most at &gt; 1 year from starting treatment (59.9%). Healthcare providers were physicians (38.7%), RN partners (38.1%), and advanced practice providers (APPs) (23.2%). Most were female (74.3%), Caucasian (80%) and worked at SCC for &gt; 5 years (56.4%). When compared with providers, many patients were not familiar with and did not perceive the supportive and integrative oncology services as important (see table). RN partners regarded physical therapy as less important than physicians and APPs (65.5% vs. 83.9% and 82.9%), while &gt; 85% of providers from each category regarded palliative care, social work and diet &amp; nutrition services as important. The most common barrier for both patients and providers was being unaware of the services (41.6% and 67.1%). Conclusions: Overall, healthcare providers were more familiar than patients with many supportive and integrative oncology services and considered most to be more important. Being unaware of the services was a common barrier identified by both providers and patients. [Table: see text]

Parametric investigation of a graphite foam evaporator in a thermosyphon with fluorinert and a silicon CMOS chip (2004)

High thermal conductivity graphitic foam was utilized as the evaporator in a modified thermosyphon. The foam was soldered directly to the back of a silicon CMOS die and mounted in a standard PGA. Fluorinert FC-87 and FC-72 were evaluated as the working fluids of choice and a variety of variables on the foams were explored. It was found that the density of the foam evaporators affected the thermal performance of the system. However, the fluid level and fluid type had very little effect on the overall performance in the system, making fabrication of a commercial device less challenging. The most significant effect on performance was the modifications to the foam structure. Slotted patterns were found to enhance the rate of return of fluid to the foam closest to the die, thus improving performance. With a slotted foam evaporator, a heat flux of 150W/cm/sup 2/ resulted in wall superheats of only 11/spl deg/C. The experimental setup used in this research gives accurate measurements of the actual active layer in the chip and temperatures less than 71/spl deg/C have been achieved at heat fluxes of 150 W/cm/sup 2/. This performance is significantly better than any prior literature data. In fact, the graphite foam thermosyphons were shown to outperform spray cooling. In addition, it was found that critical heat flux was not reached in these experiments with graphite foam evaporators at heat fluxes as high as 150 W/cm/sup 2/.
Abstract A174: High-throughput screening for natural product inhibitors of human tyrosyl-DNA-phosphodiesterase (Tdp-1) (2009)

Abstract Tyrosyl-DNA-phosphodiesterase I (Tdp-1) is part of the DNA repair complex that resolves irreversible topoisomerase I (Top1)-DNA cleavage complexes by catalyzing the hydrolysis of 3′-phosphotyrosyl bonds. A point mutation in the Tdp1 gene causes a neurological disorder called spinocerebellar ataxia with axonal neuropathy (SCAN1) (Takashima, 2002). SCAN1 cells display hypersensitivity to camptothecin (CPT), a potent Topoisomerase 1 inhibitor. Additionally, overexpression of a human Tdp1 fusion protein alleviates some of the effects of CPT treatment (Barthelmes, 2004). These observations suggest that inhibitors of Tdp1 could act synergistically with CPT in a combined therapeutic treatment for certain cancers. Despite attempts to identify synthetic small molecule inhibitors of Tdp-1, there are few verified inhibitors of this enzyme activity and none currently in clinical trials. While previous screening efforts have focused mainly upon compounds of synthetic origin (Antony, 2007), little effort has been directed towards the discovery of natural product derived inhibitors. The Molecular Targets Development Program (MTDP) at NCI-Frederick has developed a fluorescence-based assay for the rapid identification and characterization of natural product derived inhibitors of Tdp1 enzyme activity. Initial high-throughput screening work has identified several unique extracts showing potent inhibition of enzyme activity. Follow up work is currently underway to evaluate the molecular mechanism of isolated active natural compounds. Citation Information: Mol Cancer Ther 2009;8(12 Suppl):A174.
An 8.0-Gb/s HyperTransport Transceiver for 32-nm SOI-CMOS Server Processors (2012)

We present an 8.0-Gb/s HyperTransport source-synchronous I/O integrated in a 32-nm SOI-CMOS processor for high-performance servers. Based on a 45-nm design capping at 6.4 Gb/s, the 32-nm transceiver achieves up to 8.0 Gb/s over long-reach board channels by incorporating several jitter- and power-reduction enhancements. First, a high-bandwidth digital clean-up PLL is introduced to attenuate high-frequency jitter in the received forwarded clock before the data is sampled. This PLL achieves a highly programmable jitter bandwidth of 20-296 MHz (measured with 0.2 UI <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pp</sub> input jitter) and 0.90-1.50 ps output rms jitter by implementing an extended bang-bang phase detector for additional phase-error magnitude information and flexible bang-bang control of a current-starved ring-based oscillator. Second, several power-hungry circuits, namely the transmitter input FIFO and output driver as well as the receiver deserializer, are redesigned for 8.0-Gb/s operation to maintain thermal compatibility with the existing 45-nm socket package. The fabricated 20-lane I/O consumes 1.70 W at 8.0 Gb/s with an energy efficiency of 11.8 pJ/bit. This reflects a 4.9% increase in HyperTransport power consumption and only 0.3% increase in total processor target power relative to 45-nm operation at 6.4 Gb/s.
The effect of hydrofluoric acid and resin cement formulation on the bond strength to lithium disilicate ceramic (2018)

To investigate how the hydrofluoric acid (HF) concentrations applied to a lithium disilicate glass-ceramic (EMX) affects the surface morphology and microtensile bond strength (μTBS) of ceramics to dentin, using light-cured resin cements with or without UDMA. Sixty-three EMX square ceramic blocks were etched for 20 seconds using different HF concentrations (1%, 5% and 10%) and luted to dentin using two types of resin cement combinations: BisGMA/TEGDMA and BisGMA/TEGDMA/UDMA (n = 10). Each bonded EMX-dentin block was sectioned to obtain 1 mm2 sticks for μTBS evaluation. Half of the sticks were tested after 24 hours and the other half was assessed after 6 months of water storage. Data were statistically assessed using split-plot three-way ANOVA and multiple comparisons were performed using the Tukey's post hoc test (α = 0.05). One EMX sample from each HF concentration was analyzed using field-emission scanning electron microscope (FE-SEM) to characterize the etching pattern. According to the FE-SEM images, increasing the concentration of HF from 1 to 5 and then to 10% led to increased removal of glassy matrix and greater exposure of lithium disilicate crystals. The 10% HF concentration yielded higher μTBS when compared to 1% for BisGMA/TEGDMA formulation (p < 0.05); whereas HF 1% and 5% showed similar μTBS values when compared to 10% HF for BisGMA/TEGDMA/UDMA resin matrix (p > 0.05) at both storage times. Water aging decreased the μTBS values (p < 0.05), except when 10% HF was associated with BisGMA/TEGDMA resin cement. Resin cement formulation and hydrofluoric acid concentrations can interfere with the immediate and long-term glass-ceramic bond strength to dentin.
Control of Interface Nanoscale Structure Created by Plasma-Enhanced Chemical Vapor Deposition (2011)

Tailoring the structure of films deposited by plasma-enhanced chemical vapor deposition (PECVD) to specific applications requires a depth-resolved understanding of how the interface structures in such films are impacted by variations in deposition parameters such as feed position and plasma power. Analysis of complementary X-ray and neutron reflectivity (XR, NR) data provide a rich picture of changes in structure with feed position and plasma power, with those changes resolved on the nanoscale. For plasma-polymerized octafluorocyclobutane (PP-OFCB) films, a region of distinct chemical composition and lower cross-link density is found at the substrate interface for the range of processing conditions studied and a surface layer of lower cross-link density also appears when plasma power exceeds 40 W. Varying the distance of the feed from the plasma impacts the degree of cross-linking in the film center, thickness of the surface layer, and thickness of the transition region at the substrate. Deposition at the highest power, 65 W, both enhances cross-linking and creates loose fragments with fluorine content higher than the average. The thickness of the low cross-link density region at the air interface plays an important role in determining the width of the interface built with a layer subsequently deposited atop the first.

The Potency of an Anti-MERS Coronavirus Subunit Vaccine Depends on a Unique Combinatorial Adjuvant Formulation (2020)

Vaccination is one of the most successful strategies to prevent human infectious diseases. Combinatorial adjuvants have gained increasing interest as they can stimulate multiple immune pathways and enhance the vaccine efficacy of subunit vaccines. We investigated the adjuvanticity of Aluminum (alum) in combination with rASP-1, a protein adjuvant, using the Middle East respiratory syndrome coronavirus MERS-CoV receptor-binding-domain (RBD) vaccine antigen. A highly enhanced anti-MERS-CoV neutralizing antibody response was induced when mice were immunized with rASP-1 and the alum-adjuvanted RBD vaccine in two separate injection sites as compared to mice immunized with RBD + rASP-1 + alum formulated into a single inoculum. The antibodies produced also significantly inhibited the binding of RBD to its cell-associated receptor. Moreover, immunization with rASP-1 co-administered with the alum-adjuvanted RBD vaccine in separate sites resulted in an enhanced frequency of TfH and GC B cells within the draining lymph nodes, both of which were positively associated with the titers of the neutralizing antibody response related to anti-MERS-CoV protective immunity. Our findings not only indicate that this unique combinatorial adjuvanted RBD vaccine regimen improved the immunogenicity of RBD, but also point to the importance of utilizing combinatorial adjuvants for the induction of synergistic protective immune responses.
Measurement of Self-Heating of High-Frequency CMOS Clock Buffers (2022)

A technique is presented to measure the temperature of a large, dense, CMOS clock buffer while it is operating. The technique uses the subthreshold slope of a single pFET, thereby avoiding introducing special technology enhancements for thermal sensing, and uses purely simple electrical measurements. The technique is demonstrated to work in the presence of high-frequency digital switching in a realistic test site fabricated in a 14 nm finFET technology.
Anomalous Kinetic Visual Fields Found in Family Members of Patients with a Confirmed Diagnosis of Gilles de la Tourette Syndrome (1991)

Three visual manifestations of Gilles de la Tourette syndrome (TS), a neuropsychiatric disorder, have been previously reported. In this paper we report anomalies in the measured kinetic paracentral visual field of TS patients and their family members. We found that 96% of TS patients exhibited paracentral kinetic visual field defects (nasal and temporal steps, enlargement, "ringing," and/or baring of the blind spot). Ninety-three percent of fathers of TS children and, surprisingly, about 80% of mothers exhibit these characteristic visual field anomalies. Sample data and examples of family studies are reported.
Interfacial curvature effects on the monolayer morphology and dynamics of a clinical lung surfactant (2017)

The morphology of surfactant monolayers is typically studied on the planar surface of a Langmuir trough, even though most physiological interfaces are curved at the micrometer scale. Here, we show that, as the radius of a clinical lung surfactant monolayer-covered bubble decreases to ∼100 µm, the monolayer morphology changes from dispersed circular liquid-condensed (LC) domains in a continuous liquid-expanded (LE) matrix to a continuous LC linear mesh separating discontinuous LE domains. The curvature-associated morphological transition cannot be readily explained by current liquid crystal theories based on isotropic domains. It is likely due to the anisotropic bending energy of the LC phase of the saturated phospholipids that are common to all natural and clinical lung surfactants. This continuous LC linear mesh morphology is also present on bilayer vesicles in solution. Surfactant adsorption and the dilatational modulus are also strongly influenced by the changes in morphology induced by interfacial curvature. The changes in morphology and dynamics may have physiological consequences for lung stability and function as the morphological transition occurs at alveolar dimensions.
Toughness of Carbon Fiber/Epoxy Laminates Based on Intermediate Modulus Fibers (1993)

Assessing Concept Weighting in Integer Linear Programming based Single-document Summarization (2016)

Some of the recent state-of-the-art systems for Automatic Text Summarization rely on the concept-based approach using Integer Linear Programming (ILP), mainly for multi-document summarization. A study on the suitability of such an approach to single-document summarization is still missing, however. This work presents an assessment of several methods of concept weighing for a concept-based ILP approach on the single-document summarization scenario. The unigram and bigram representations for concepts are also investigated. The experimental results obtained on the DUC 2001-2002 and the CNN corpora show that bigrams are more suitable than unigrams for the representation of concepts. Among the concept scoring methods investigated, the sentence position method presented the best performance on all evaluation corpora.
