Reduced Phase Separation and Slowing of Dynamics in Polyurethanes with Three-Dimensional POSS-Based Cross-Linking Moieties (2015)

Octa-OH-functional POSS has been incorporated into a model polyurethane elastomer as a comparatively massive and notionally “robust” 3-dimensional cross-linking core. The effects of this cross-linking moiety on the morphology and molecular dynamics of the system are studied over a range of size and time scales. Microscopy, scattering, spectroscopic, thermal, and dielectric techniques, in agreement with each other, show that the covalent inclusion of the cross-linking particles restricts microphase separation, inhibits the formation of hard-block domains, and decelerates the motional dynamics of the polyurethane backbone. The effects on both the morphology and the dynamics of the polyurethane system are not continuous but occur in a steplike manner in the loading region of 4–6 wt % POSS. This critical region is thought to correspond to a sterically induced transition from one dominant morphology (microphase segregated) to an increasingly homogeneous nanophase segregated domain morphology. Contrary to expectations, cross-linking, even by the presumably rigid siliceous nanoparticles, reduces the mechanical modulus. In conjunction with the reduction of microphase separation, this observation indicates that the hard microdomains reinforce the polymer more effectively than the chemical cross-links.
The chemically reduced CuO–Co3O4 composite as a highly efficient electrocatalyst for oxygen evolution reaction in alkaline media (2019)

The fabrication of efficient, alkaline-stable and nonprecious electrocatalysts for the oxygen evolution reaction is highly needed; however, it is a challenging task.
Temporal Information Retrieval: Challenges and Opportunities (2011)

Time is an important dimension of any information space. It can be very useful for a wide range of information retrieval tasks such as document exploration, similarity search, summarization, and clustering. Traditionally, information retrieval applications do not take full advantage of all the temporal information embedded in documents to provide alternative search features and user experience. However, in the last few years there has been exciting work on analyzing and exploiting temporal information for the presentation, organization, and in particular the exploration of search results. In this paper, we review the current research trends and present a number of interesting applications along with open problems. The goal is to discuss interesting areas and future work for this exciting field of information management.
Cigarette smoke induces promoter methylation of single‐stranded DNA‐binding protein 2 in human esophageal squamous cell carcinoma (2010)

Esophageal squamous cell carcinoma (ESCC) is the sixth most frequent cause of cancer death in the world, and cigarette smoke is a key factor in esophageal carcinogenesis. To identify molecular changes during cigarette smoke-induced ESCC, we examined the methylation status of 13 gene promoters in the human immortalized, nontumorigenic esophageal epithelial cell line (Het-1A) that were exposed to mainstream (MSE) or sidestream cigarette smoke extract (SSE) for 6 months in culture. The promoter of sequence-specific single-stranded DNA-binding protein 2 (SSBP2) was methylated in the Het-1A cells exposed to MSE (MSE-Het-1A). Promoter methylation (86%, 56/70) and downregulation of SSBP2 expression were frequently detected in tumor tissues from ESCC patients. In addition, reintroduction of SSBP2 in an ESCC cell line (TE1) that does not express SSBP2 and in the MSE-Het-1A cells inhibited expression of LRP6 and Dvl3, which are mediators of the Wnt signaling pathway. SSBP2 expression markedly decreased the colony-forming ability of ESCC cell lines and significantly inhibited cell growth of the MSE-Het-1A cells. Our results indicate that cigarette smoking is a cause of SSBP2 promoter methylation and that SSBP2 harbors a tumor suppressive role in ESCC through inhibition of the Wnt signaling pathway.
Combination of InP MZM Transmitter and Monolithic CMOS 8-State MLSE Receiver for Dispersion Tolerant 10 Gb/s Transmission (2008)

We demonstrate that InP modulators together with 1 sample/bit MLSE gives equivalent performance to linear electro-optic Mach-Zehnder modulators combined with oversampled MLSE, potentially providing significant reduction in power dissipation and footprint.
Pd(OAc)2-catalyzed asymmetric hydrogenation of sterically hindered N-tosylimines (2018)

Asymmetric hydrogenation of sterically hindered substrates still constitutes a long-standing challenge in the area of asymmetric catalysis. Herein, an efficient palladium acetate (an inexpensive Pd salt with low toxicity) catalyzed asymmetric hydrogenation of sterically hindered N-tosylimines is realized with high catalytic activities (S/C up to 5000) and excellent enantioselectivities (ee up to 99.9%). Quantum chemical calculations suggest that uniformly high enantioselectivities are observed due to the structurally different S- and R-reaction pathways.
Permeability of pure and mixed gases in silicone rubber at elevated pressures (1990)

Abstract The transport properties of silicone rubber are reported at 35°C for a series of pure gases (He, N 2 , CH 4 , CO 2 , and C 2 H 4 ) and gas mixtures (CO 2 /CH 4 and N 2 /CO 2 ) for pressures up to 60 atm. The effects of pressure and concentration on the permeability of various gases have been analyzed to consider plasticization and hydrostatic compression effects. Over an extended pressure and concentration range, both compression of free volume and eventual plasticization phenomena were observed for the various penetrants. In pure component studies, plasticization effects tended to dominate hydrostatic compression effects for the more condensible penetrants (C 2 H 4 and CO 2 ) while the reverse was true for the low sorbing N 2 and He. These issues are discussed in terms of penetrant diffusion coefficients versus pressure to clarify the interplay between the opposing effects for the penetrants of markedly different solubilities. Additional insight into the somewhat complex interplay of the plasticization and hydrostatic compression effects are given by mixed gas permeation results. It was found that the permeability of nitrogen in a 10/90 CO 2 /N 2 and a 50/50 CO 2 /N 2 mixture was increased by the presence of CO 2 because the plasticizing nature of CO 2 is able to overcome nitrogen's compression effect.
Abstract WP152: Changes In Thrombus Fibrin Content By Time In Patients Undergoing Thrombectomy (2022)

Introduction: Understanding clot composition and associated genomic, epigenomic, and proteomic signatures could provide insight into thrombus biology and etiology, and aid in prognosis in stroke. We report preliminary analysis of histology evaluations in subjects enrolled in the INSIGHT Registry, a multicentered ‘multi-omic’ analysis of thrombi associated with acute hemorrhagic and ischemic stroke this multi-omic clot collection registry. Our aim was to determine potential histology differences in thrombi as a consequence of infarct time (time from last known normal to thrombectomy). Material and Methods: Subjects age ≥18 years, treated frontline with the Penumbra System for thrombectomy are included in this analysis. Patient demographics, medical history, radiographic, and procedural information are collected in conjunction with extracted clot and concurrent extracranial arterial blood. Enrollment, data collection, and data monitoring are ongoing for the INSIGHT registry. While the protocol includes analysis for proteomics and transcriptomics, for this analysis we used automated histology. An MSB Trichrome stain was used to evaluate the tissue. Composition was determined by automated pixel analysis, with the values representing ratios of the overall clot. Results: Samples from 60 subjects who were enrolled from 10 sites between 02/2021 and 07/2021. Analysis of the thrombi successfully determined the relative portions of fibrin, red blood cells (RBCs), and platelets (PLT). The median percentage of fibrin in the thrombi was 44.0% (IQR 29.0 - 57.6; N=60). The median time interval from Last Known Well to recanalization was 4.0 hours (IQR 2.9-12.8 hours; N=55). There was no correlation between the time interval of stroke and the percent of fibrin in the thrombus (Pearson correlation coefficient -0.01, p 0.94). Conclusion: These preliminary results demonstrate a lack of relationship between time interval of the stroke and clot histology composition with relation to fibrin. Thrombus fibrin composition is likely more related to other factors, and not predominantly related to time. We are currently investigating potential relationships to demographics and co-morbidities.

Linear and Two-Photon Photophysical Properties of a Series of Symmetrical Diphenylaminofluorenes (2004)

A series of linear, symmetrical, diphenylaminofluorene-based materials are reported. The series investigated was model 9,9-didecyl-2,7-bis(N,N-diphenylamino)fluorene (1), oligomer 9,9-didecyl-N,N-bis(9,9-didecyl-7-N,N-diphenylaminofluoren-2-yl)-N,N-diphenyl-fluorene-2,7-diamine (2), and poly(9,9-didecyl-2,7-diphenylaminofluorene) (3). Structural characterization and photophysical properties, including linear absorption, quantum yields, single photon fluorescence, and two-photon absorption (2PA) spectra, were studied in polar and nonpolar solvents. 2PA spectra were determined by two independent methods: a nonlinear transmission method employing a femtosecond white-light continuum (WLC) and a two-photon fluorescence (2PF) method. Polymer 3, a low-molecular-weight polymer with fourteen fluorene units, exhibited a very large two-photon absorption cross-section of 17 200 and 6800 × 10-50 cm4 s photon-1 molecule-1 as estimated from the WLC and 2PF methods, respectively.
A Condition to Get Rid of Slope Compensation in Peak Current-Mode Controllers (2020)

Current-mode control is used in Switched-Mode Power Supplies (SMPSs) due to its high stability and quick response. Moreover, peak current-mode control, as one of the current-mode control techniques is often used due to its ease of design and capability of overcurrent protection. However, peak current-mode control sometimes makes output oscillations in certain conditions. Accordingly, SMPSs designers often use slope compensation to prevent output oscillation. However, it has some challenges such as design complexity and delayed response. Therefore, in this research, the authors derived a conditional expression to replace the use of slope compensation based on multi-cycle digital control. The proposed quantity along with its derivation is provided in this manuscript. Furthermore, the carried-out investigations validate its applicability.
824 Modeling a human sensibility system for timbre of "Nohteki" (2000)

The purpose of this work is to realize a human sensibility system for timbre of a Japanese traditional flute, "Nohteki". Two approaches are used for several data sampling about timbre. One is the evaluation of the physics characteristics about "Nohteki" sounds with time, spectrum analysis, and wavelet transform. The other is the evaluation of the sensibility about "Nohteki" sounds through the questionnaire. At first, several axes to explain the important factors are found with factor analysis from the sensibility of listeners about "Nohteki" sounds by SD method. Evaluate equations between the effective physics values as input parameters and the sensibility factors as output parameters are established by using multiple regression analysis. Furthermore, the non-liner relation of the sensibility is considered by using a neural network, the correlation between the sensibility of listeners and the physics values of "Nohteki" sounds is clarified. As a result, it can be said to realize a human sensibility system for timbre of "Nohteki".
Prediction of Evaporative Effects Within the Blading of an Industrial Axial Compressor (2010)

The results of a compressor flow-analysis code calibration study for estimating the effects of water evaporation within the blade rows of industrial axial compressors are presented. In this study, a mean-line code was chosen for the calibration tool due to its accepted use during preliminary design studies, at which time during the compressor design process one would logically consider power augmentation through wet compression. The calibrated code features a nonequilibrium thermodynamic single-droplet evaporation model augmented with an empirical splashing model, which, as input, uses measurements of droplet spectra data taken on water injection nozzles in an intake rig configured with realistic length scales. In addition, a wetted-airfoil-surface flow-angle deviation model is applied to predict changes in compressor stage characteristics, which, in turn, affect the inlet mass flow of the compressor. The test vehicle for calibration was a 50 Hz Alstom industrial gas turbine. Once calibrated, the code was successfully utilized to predict wet-compression effects for three additional like-family Alstom gas turbines operating at constant speed while under full load. The effects modeled by the code include bleed supply pressure suck-down and bleed temperature cool-down effects, as well as compressor inlet mass flow and power consumption effects.
Induction of resting spore germination in Entomophthora aphidis by long-day light conditions (1976)

A small proportion of Entomophthora aphidis Hoffmann resting spores produce germ tubes within a few days upon incubation at 20 °C with ample moisture in the dark without chemical treatment or exogenous nutrient. However, the germ tubes do not branch and germ conidia are not produced until after much longer incubation, and then only sparsely. Light periods of 14 h or more in a 24-h day greatly enhance the germination level but seldom result in germination of more than 50% of the spores. Branching of the germ tubes, germ conidia production, and germination of germ conidia all occur rapidly under long-day conditions. The principal germination interval is between 10 and 30 days under the conditions used and it was estimated that the germination level would stabilize after about 60 days. Variability in germination from plate to plate made with the same spore preparation was from about 25 to 50%.
Implementing Best Concrete Pavement Spall Repairs (2008)

The implementation project, 5-5110, Implementation of Best Spall Repair Practices for Concrete Pavement, was initiated to assist the Texas Department of Transportation (TxDOT) in using more durable repair practices and materials for concrete spalls, especially in continuously reinforced concrete pavement (CRCP). In the related previous research project 0-5110, Best Practices for Concrete Pavement Spall Repairs, researchers discovered that TxDOT already had several technical tools in place to make it easier for district personnel to find and specify the most promising materials for their concrete spall repair projects.
The impact of rare protein coding genetic variation on adult cognitive function (2022)

Abstract Compelling evidence suggests that cognitive function is strongly influenced by genetics. Here, we conduct a large-scale exome study to examine whether rare protein coding variants impact cognitive function in the adult population (N=485,930). We identify eight genes associated with adult cognitive function through rare coding variants with large effects. We demonstrate how the dosage of a single gene, KDM5B , may determine the variability of cognitive, behavioral, and molecular traits in mice and humans. We further provide evidence that rare and common variants overlap in association signals and contribute additively to cognitive function. Our findings uncover a contribution of rare coding variants to cognitive function and highlight that the spectrum of cognitive function in the normal adult population is influenced by the action of single genes.
Angular analysis of the decay B+ → K∗(892)+μ+μ− in proton-proton collisions at $$ \sqrt{\mathrm{s}} $$ = 8 TeV (2021)

A bstract Angular distributions of the decay B + → K ∗ (892) + μ + μ − are studied using events collected with the CMS detector in $$ \sqrt{\mathrm{s}} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> </mml:math> = 8 TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 20.0 fb − 1 . The forward-backward asymmetry of the muons and the longitudinal polarization of the K ∗ (892) + meson are determined as a function of the square of the dimuon invariant mass. These are the first results from this exclusive decay mode and are in agreement with a standard model prediction.
The Active Conformation of Teleocidins : Design and Synthesis of New Active Molecules (1994)

This review deals with structure-activity relationships, conformational analysis of teleocidins and creation of new active compounds for the determination of active conformation of teleocidins. Phorbol esters containing 12-O-tetradecanoylphorbol-13-acetate (TPA) and teleocidins which are classified as TPA-type tumor promoters exhibit potent tumor-promoting activity as well as many important biological activities connected with cell prolification and cell differentiation. Teleocidins are known to exist in an equilibrium between two conformational states in solution, the twist and the sofa forms. The low energy barrier between the two conformers makes it difficult to identify the mode of interaction of these promoters with common macromolecular targets. Design and synthesis of molecules having a new skeleton (benzolactams) and producing two conformations of teleocidins solve the problem. Benzolactams become the simplest molecule reproducing the conformation and activity of teleocidin, and will be a useful tool for the study of tumor-promotion and cell differentiation.
Pulsed laser ultrasonic excitation and heterodyne detection for in situ process control in laser 3D manufacturing (2016)

An all optical, in situ, process control diagnostic is presented with applicability to additive manufacturing. The diagnostic combines laser ultrasonics with laser heterodyne spectroscopy to measure the local temperature in the heat affected zone. The technique is time resolved (ns resolution) and can be adapted to measuring the cooling rate at the process location. With this knowledge, it permits the development of a corrective action step if the heating/cooling properties are found to be outside acceptable bounds. Feasibility of the diagnostic is presented using solid metal coupons of aluminum, stainless steel, and copper.
A Rigid Body and Spring Model of the Lumbar Spine Which Considers the Mechanical Loads at the Bone-Screw Interface (2009)

A spinal instrument with pedicle screws is one of the most effective surgical techniques for correction of spinal deformity. However, when excessive mechanical loads are applied on the implant upon the fixation, there is a concern for back out of the screw in the cases with poor bone condition such as osteoporosis. For that reason, the mechanical loads at the bone-screw interface should be analyzed for safe and successful correction.

Learning 6-DoF Object Poses to Grasp Category-Level Objects by Language Instructions (2022)

This paper studies the task of any objects grasping from the known categories by free-form language instructions. This task demands the technique in computer vision, natural language processing, and robotics. We bring these disciplines together on this open challenge, which is essential to human-robot interaction. Critically, the key challenge lies in inferring the category of objects from linguistic instructions and accurately estimating the 6-DoF information of unseen objects from the known classes. In contrast, previous works focus on inferring the pose of object candidates at the instance level. This significantly limits its applications in real-world scenarios. In this paper, we propose a language-guided 6-DoF category-level object localization model to achieve robotic grasping by comprehending human intention. To this end, we propose a novel two-stage method. Particularly, the first stage grounds the target in the RGB image through language description of names, attributes, and spatial relations of objects. The second stage extracts and segments point clouds from the cropped depth image and estimates the full 6-DoF object pose at category-level. Under such a manner, our approach can locate the specific object by following human instructions, and estimate the full 6-DoF pose of a category-known but unseen instance which is not utilized for training the model. Extensive experimental results show that our method is competitive with the state-of-the-art language-conditioned grasp method. Importantly, we deploy our approach on a physical robot to validate the usability of our framework in real-world applications. Please refer to the supplementary for the demo videos of our robot experiments.
When Sessile Drops Are No Longer Small: Transitions from Spherical to Fully Flattened (2010)

We measured the dimensions and contact angles of sessile drops using three liquids on a variety of polymer and silicon surfaces. Drops ranged in size from a few microliters to several milliliters. With increasing liquid volume, heights of the drops initially rose steeply and then gradually tapered to a constant value. The heights of small, undistorted drops as well as the heights of the largest drops were accurately predicted by well-established models. A recently derived expression for meniscus height was used to estimate the heights of intermediate-size drops. While it was not exact, this expression produced reasonable approximations without having to resort to iterative numerical methods. We also identified transition points where gravity began to distort drop shape and ultimately limited drop height. Relatively simple closed analytical expressions for estimating these transition points were also derived. Predicted values of the height and volume at the onset of distortion agreed fairly well with the measured ones. Contact angles carefully measured by the tangent method were independent of drop size.
