Resist outgassing as a function of differing photoadditives (1999)

The effect of different photoadditives in high and low activation energy resist resins on resist outgassing during lithographic exposure was studied by quartz microbalance and gas chromatography/mass spectroscopy techniques. The resist outgassing was analyzed both qualitatively and quantitatively and structure-property relationships were developed between resist outgassing and the molecular structure of photoacid generators and additives. The photoadditives examined include, aryl iodonium perfluoroalkylsulfonates, triarylsulfonium perfluoroakylsulfonates, photogenerators of sulfamic acids, 2-nitrobenzyl PAG's and doxyl derivatives.

Structure-Based Design of 3-(4-Aryl-1 H -1,2,3-triazol-1-yl)-Biphenyl Derivatives as P2Y 14 Receptor Antagonists (2020)

UDP and UDP-glucose activate the P2Y14 receptor (P2Y14R) to modulate processes related to inflammation, diabetes, and asthma. A computational pipeline suggested alternatives to naphthalene of a previously reported P2Y14R antagonist (3, PPTN) using docking and molecular dynamics simulations on a hP2Y14R homology model based on P2Y12R structures. By reevaluating the binding of 3 to P2Y14R computationally, two alternatives, i.e., alkynyl and triazolyl derivatives, were identified. Improved synthesis of fluorescent antagonist 4 enabled affinity quantification (IC50s, nM) using flow cytometry of P2Y14R-expressing CHO cells. p-F3C-phenyl-triazole 65 (32) was more potent than a corresponding alkyne 11. Thus, additional triazolyl derivatives were prepared, as guided by docking simulations, with nonpolar aryl substituents favored. Although triazoles were less potent than 3 (6), simpler synthesis facilitated further structural optimization. Additionally, relative P2Y14R affinities agreed with predicted binding of a...
Learning to Reconstruct Texture-less Deformable Surfaces from a Single View (2018)

Recent years have seen the development of mature solutions for reconstructing deformable surfaces from a single image, provided that they are relatively well-textured. By contrast, recovering the 3D shape of texture-less surfaces remains an open problem, and essentially relates to Shape-from-Shading. In this paper, we introduce a data-driven approach to this problem. We introduce a general framework that can predict diverse 3D representations, such as meshes, normals, and depth maps. Our experiments show that meshes are ill-suited to handle texture-less 3D reconstruction in our context. Furthermore, we demonstrate that our approach generalizes well to unseen objects, and that it yields higher-quality reconstructions than a state-of-the-art SfS technique, particularly in terms of normal estimates. Our reconstructions accurately model the fine details of the surfaces, such as the creases of a T-Shirt worn by a person.
Dependence of Electrostatic Field Strength on Image Transfer Roller Dimensions in a Toner Transfer Region (2012)

Using an expansion of electrostatic potential in terms of partial solutions of the Poisson equations, a distribution of electrostatic field strength in a two-dimensional (2D) toner transfer system region between the toner and the paper has been calculated. The results have been obtained for a system in which photoreceptor and toner transfer element is a roller with a finite radius. In these calculations, the photoreceptor, the toner, and the paper have been characterized by the values of their thickness and dielectric permittivity. Results have been obtained when the transfer element is flat and when it is shaped as a roller with a finite radius. It is concluded that the one-dimensional (1D) approximation cannot be applied to calculate the electric field when the roller radius is close to or less than the radius of the cylinder-shaped photoreceptor. The limits of applicability of the dielectric thickness have been demonstrated.
Application of Variable Period Time Spectral Method to Unsteady Flow Around Rectangular Cylinder (2009)

Based on the characteristic of time periodic unsteady flow,the time spectral method was applied to two-dimensional incompressible laminar flow around a rectangular cylinder in infinite medium at low Reynolds numbers.A variable time period method based on residual gradients was combined to iterate the variables and time period simultaneously because of the unknown time period of flow around the cylinder.The accuracy and convergence rate of the time spectral method were investigated and the influence of different parameters on the final results was analyzed.The results show that the present method could simulate the vortex shedding phenomenon accurately and the time cost could decrease to 10%-25% of that of the conventional dual time stepping method based on the finite difference scheme.The Strouhal number and drag characteristics confirm the feasibility of the present method.Our results indicate that the variable time period method is insensitive to parameter selection and can predict the time period accurately.

Reliable Physical-layer Network Coding Supporting Real Applications (2016)

This paper presents the first reliable physical-layer network coding (PNC) system that supports real TCP/IP applications for the two-way relay network (TWRN). Theoretically, PNC could boost the throughput of TWRN by a factor of 2 compared with traditional scheduling (TS) in the high signal-to-noise (SNR) regime. Although there have been many theoretical studies on PNC performance, there have been relatively few experimental and implementation efforts. Our earlier PNC prototype, built in 2012, was an offline system that processed signals offline. For a system that supports real applications, signals must be processed online in real-time. Our real-time reliable PNC prototype, referred to as RPNC, solves a number of key challenges to enable the support of real TCP/IP applications. The enabling components include: 1) a time-slotted system that achieves us-level synchronization for the PNC system; 2) reduction of PNC signal processing complexity to meet real-time constraints; 3) an ARQ design tailored for PNC to ensure reliable packet delivery; 4) an interface to the application layer. We took on the challenge to implement all the above with general-purpose processors in PC through an SDR platform rather than ASIC or FPGA. With all these components, we have successfully demonstrated image exchange with TCP and twoparty video conferencing with UDP over RPNC. Experimental results show that the achieved throughput approaches the PHYlayer data rate at high SNR, demonstrating the high efficiency of the RPNC system.
Measurement of Effective Refractive Index of Nematic Liquid Crystal in Fabry-Perot Etalon (2015)

We report a measurement of the effective refractive index of a nematic liquid crystal (NLC) inside a Fabry-Perot (FP) etalon according to the applied electric fields. The effective refractive index of the NLC depends on the intensity of the applied electric field. A wavelength-swept laser with a polygon-scanner-based wavelength filter is used as a wide-band optical source to measure the effective refractive index of the NLC. The bandwidth of the optical source is greater than 90 nm around 1300 nm. The fabricated NLC FP etalon consists of glass substrates, gold layers as the electrodes with highly reflective surfaces, polyimide layers as the planar alignment layers, and an LC layer. Furthermore, we measured the Freedericksz transition voltages for three types of NLC FP etalons having thicknesses of $30.6{\mu}m$ , $55.4{\mu}m$ , and $108.8{\mu}m$ . The Freedericksz transition voltages in the three cases are nearly equal. The measured effective refractive indices in the three cases decreased from 1.67 to 1.51 as the applied electric field intensity was increased. Beyond the threshold electric field, the effective refractive indices quickly decreased and eventually saturated at a value of 1.51 for all cases.
Aggressive pituitary adenomas occurring in young patients in a large Polynesian kindred with a germline R271W mutation in the AIP gene (2009)

This kindred exemplifies the aggressive features of pituitary adenomas associated with AIP mutations, while genetic analyses among three R271W FIPA families indicate that R271W represents a mutational hotspot that should be studied further in functional studies.
Structural Requirements for the Tissue-Specific and Tissue-General Functions of the Caenorhabditis elegans Epidermal Growth Factor LIN-3 (1999)

Caenorhabditis elegans lin-3 encodes a homolog of the epidermal growth factor (EGF) family of growth factors. LIN-3 is the inductive signal for hermaphrodite vulval differentiation, and it is required for animal viability, hermaphrodite fertility, and the specification of anterior cell fates in the male B cell lineage. We describe the cloning of a lin-3 homolog from C. briggsae, sequence comparison of C. elegans lin-3 with C. briggsae lin-3, and the determination of molecular lesions in alleles of C. elegans lin-3, including three new alleles. We also analyzed the severity of phenotypes caused by the new and existing alleles of lin-3. Correlation of mutant phenotypes and their molecular lesions, as well as sequence comparison between two species, reveal that the EGF motif and the N-terminal portion of the cytoplasmic domain are important for the functions of LIN-3 in all tissues, while the C-terminal portion of the cytoplasmic domain is involved in the tissue-specific functions of lin-3. We discuss how the structure of lin-3 contributes to its functions in multiple developmental processes.
Model-informed machine learning for multi-component T 2 relaxometry (2020)

Recovering the T<sub>2</sub> distribution from multi-echo T<sub>2</sub> magnetic resonance (MR) signals is challenging but has high potential as it provides biomarkers characterizing the tissue micro-structure, such as the myelin water fraction (MWF). In this work, we propose to combine machine learning and aspects of parametric (fitting from the MRI signal using biophysical models) and non-parametric (model-free fitting of the T<sub>2</sub> distribution from the signal) approaches to T<sub>2</sub> relaxometry in brain tissue by using a multi-layer perceptron (MLP) for the distribution reconstruction. For training our network, we construct an extensive synthetic dataset derived from biophysical models in order to constrain the outputs with a priori knowledge of in vivo distributions. The proposed approach, called Model-Informed Machine Learning (MIML), takes as input the MR signal and directly outputs the associated T<sub>2</sub> distribution. We evaluate MIML in comparison to a Gaussian Mixture Fitting (parametric) and Regularized Non-Negative Least Squares algorithms (non-parametric) on synthetic data, an ex vivo scan, and high-resolution scans of healthy subjects and a subject with Multiple Sclerosis. In synthetic data, MIML provides more accurate and noise-robust distributions. In real data, MWF maps derived from MIML exhibit the greatest conformity to anatomical scans, have the highest correlation to a histological map of myelin volume, and the best unambiguous lesion visualization and localization, with superior contrast between lesions and normal appearing tissue. In whole-brain analysis, MIML is 22 to 4980 times faster than the non-parametric and parametric methods, respectively.
Interactive app traffic: An action-based model and data-driven analysis (2016)

Many popular smartphone apps involve human interaction through the entire session; e.g. apps for web browsing, making reservations and online gaming. In this work, we characterize bi-directional interactive app traffic in the timescale of seconds, that is shaped by the human interaction. We collect and analyze a dataset comprising 1500 interactive app sessions. The combined uplink and downlink traffic bursts are the outcome of user-server interactions, which we label as actions. Within each action, we discover high correlation between the number of uplink and downlink packets reaching 0.98. Our study reveals that the distribution of action duration and interarrival can be approximated with exponential or gamma distributions. The analysis provides insights on the temporal characteristics of bi-directional packet bursts associated with actions, during an app session. We show that action-based service at access points (APs), where actions constitute the service units rather than packets, can reduce service delay by 50%.
Formation of a Silicate L 3 Phase with Continuously Adjustable Pore Sizes (1997)

The lyotropic L 3 phase was used as a template to form nanoporous monolithic silicates with continuously adjustable pore sizes. The monolith was optically isotropic and transparent with a nonperiodic network. The pore size was adjusted by a change in the solvent volume fraction rather than by a change of the surfactant. Unlike other silicates, the bicontinuous pores were water-filled; removal of surfactant was not necessary to access the pores. Measured characteristic dimensions were from six to more than 35 nanometers. For a given solvent fraction, x-ray scattering indicated little variation of pore widths, in marked contrast to the polydisperse pores of aerogels.
Thixotropic Conformance Sealant for Horizontal or Highly Deviated Wellbores (2017)

Abstract Excessive undesired fluid production, either water or gas, is a widespread problem withinthe oil and gas industry that can detrimentally affect the profitability of hydrocarbon-producing reservoirs, thus limiting their economic life. A wide variety of chemical technologies have been implemented throughoutthe years for controlling unwanted fluid production with some degree of success. However, when these types of treatments are applied to horizontal or highly deviated wells, placement control becomes a critical factor. Depending on fluid density differences and wellbore deviation, conventional conformance treatments can slump/rise along horizontal sections, compromising the placement accuracy and overall treatment success. This paper discusses the development and application of a thixotropic conformance sealant (TCS) system specifically designed to help control unwanted fluid production in horizontal or highly deviated wellbores. The stress-dependent (thixotropic) rheological properties of the TCS system provides rapid viscosity increase afterplacement, allowing the treatment to remain in place until in-situ crosslinking occurs at a predicted time, helping provide a competent and precise seal across the targeted area. The TCS system is based on an organic-crosslinked polymer gel system combined with optimized rheological modifiers. It provides a predictable and controllable crosslinking time to obtain adequate placement. It can be placed into the wellbore by bullheading or using a coiled tubing (CT) unit. Once it is strategically placed into the zone to be shut off, in-situ gelation is activated by the reservoir temperature, plugging the permeability of the treated area, thereby limiting undesired fluid flow. The TCS system can be formulated to allow penetration into the formation matrix or to bridge off at the formation face for limited leakoff, to help provide a controlled and shallow penetration at the formation face. Laboratory data ispresentedas well as preliminary results of field applications. Other thanthixotropic cement slurries, the TCS system is the first conformance technology tailored to horizontal applications within the oil and gas industry, helping reduce excessive undesired fluid production while extending the economic life of the wellbore and reservoir. The TCS system is applicable to different completion types such as openhole, slotted liners, openhole gravel-packs (OHGPs), and casedhole gravel-packs (CHGPs), among others.
Observation of a Half Step Magnetization in the{Cu3}-Type Triangular Spin Ring (2006)

We report pulsed field magnetization and ESR experiments on a {Cu3} nanomagnet, where antiferromagnetically coupled Cu(2+) (S = 1/2) ions form a slightly distorted triangle. The remarkable feature is the observation of a half step magnetization, hysteresis loops, and an asymmetric magnetization between a positive and a negative field in a fast sweeping external field. This is attributed to an adiabatic change of magnetization. The energy levels determined by ESR unveil that the different mixing nature of a spin chirality of a total S = 1/2 Kramers doublet by virtue of Dzyaloshinskii-Moriya interactions is decisive for inducing half step magnetization.

Formulation of a Strain Hardening Model for Gasket Creep Relaxation (2011)

This paper proposes a novel strain hardening model for investigating gasket creep relaxation under compressive step-loading at room temperature. A closed form solution is developed for predicting the steady-state gasket pressure. Step-loading of the gasket may be directly achieved and controlled, or indirectly estimated through the bolt tightening and re-tightening torque. The effect of gasket material, time duration at each stress level, as well as the geometric parameters of the gasket is investigated. An experimental procedure and test set-up are used to validate the proposed gasket model.
Scheduling considerations for building dynamic verification tools for MPI (2008)

Dynamic verification methods are the natural choice for formally verifying real world programs when model extraction and maintenance are expensive. Message passing programs written using the MPI library often fall under this category, especially when these programs have to be verified after being ported to new platforms and iteratively optimized. However, implementing dynamic verification tools for MPI requires solving many problems pertaining to the scheduling realities of the MPI runtime. In this paper, we describe the progression of our ideas during the development of our dynamic verification tool for MPI programs, called in-situ partial order (ISP). Each idea developed in this progression relates to our dual goals of ensuring full coverage of all representative interleavings (in the sense of partial order reduction) among MPI processes, and forcing the MPI runtime to affect these interleavings. We briefly examine similar issued faced by other builders of dynamic verification tools. We conclude with observations backing the growing importance of addressing scheduling issues in future dynamic verification tools for various concurrency APIs.
Microscope-AOtools: a generalised adaptive optics implementation (2020)

Aberrations arising from sources such as sample heterogeneity and refractive index mismatches are constant problems in biological imaging. These aberrations reduce image quality and the achievable depth of imaging, particularly in super-resolution microscopy techniques. Adaptive optics (AO) technology has been proven to be effective in correcting for these aberrations, thereby improving the image quality. However, it has not been widely adopted by the biological imaging community due, in part, to difficulty in set-up and operation of AO. The methods for doing so are not novel or unknown, but new users often waste time and effort reimplementing existing methods for their specific set-ups, hardware, sample types, etc. Microscope-AOtools offers a robust, easy-to-use implementation of the essential methods for set-up and use of AO elements and techniques. These methods are constructed in a generalised manner that can utilise a range of adaptive optics elements, wavefront sensing techniques and sensorless AO correction methods. Furthermore, the methods are designed to be easily extensible as new techniques arise, leading to a streamlined pipeline for new AO technology and techniques to be adopted by the wider microscopy community.
Relaxation and Block-Relaxation Procedures for the Dual Formulation of the Signorini-Coulomb Frictional Contact (2009)

This paper is devoted to the solution of frictional contact problems. The contact is modeled by the Signorini's law of unilateral contact and the friction by the Coulomb's friction law. A condensed duality formulation on the contact zone is introduced. A quasi-variational inequality is obtained and solved numerically by relaxation and block-relaxation procedures. The numerical example of the contact of an elastic body with a rigid support is presented.
Quantizing Signals for Linear Classification (2019)

In many machine learning applications, once we have learned a classifier, in order to apply it, we may still need to gather features from distributed sensors over communication constrained channels. In this paper, we propose a polynomial complexity algorithm for feature quantization tailored to minimizing the classification error of a linear classifier. Our scheme produces scalar quantizers that are well-tailored to delay-sensitive applications, operates on the same training data used to learn the classifier, and allows each distributed sensor to operate independently of each other. Numerical evaluation indicates up to 65% benefits over alternative approaches. Additionally, we provide an example where, jointly designing the linear classifier and the quantization scheme, can outperform sequential designs.
Adult T-cell leukemia/lymphoma on a background of clonally expanding human T-cell leukemia virus type-1-positive cells (1996)

Tumorous and nontumorous samples from patients with various forms of adult T-cell leukemia/lymphoma (ATLL) were analyzed using the sensitive inverse polymerase chain reaction (PCR) technique. In all samples, oligoclonal expansion of human T-cell leukemia virus (HTLV)-1 bearing T cells were detected, even for the tumorous samples that were mainly monoclonal by Southern blotting. For one case of smouldering ATLL, chemotherapy apparently reduced the number of detectable clones. Taken together with similar data on asymptomatic and symptomatic HTLV-1 carriers without malignancy, it would appear that ATLL appears on a prior background of HTLV-1-initiated oligoclonal expansion.
