Charge‐Carrier Balance and Color Purity in Polyfluorene Polymer Blends for Blue Light‐Emitting Diodes (2011)

Abstract A study of an efficient blue light‐emitting diode based on a fluorescent aryl polyfluorene (aryl‐F8) homopolymer in an inverted device architecture is presented, with ZnO and MoO 3 as electron‐ and hole‐injecting electrodes, respectively. Charge‐carrier balance and color purity in these structures are achieved by incorporating poly(9,9‐dioctylfluorene‐co‐N‐(4‐butylphenyl)‐diphenylamine (TFB) into aryl‐F8. TFB is known to be a hole‐transporting material but it is found to act as a hole trap on mixing with aryl‐F8. Luminance efficiency of ≈6 cd A −1 and external quantum efficiency (EQE) of 3.1% are obtained by adding a small amount (0.5% by weight) of TFB into aryl‐F8. Study of charge injection and transport in the single‐carrier devices shows that the addition of a small fraction of hole traps is necessary for charge‐carrier balance. Optical studies using UV–vis and fluorescence spectroscopic measurements, photoluminescence quantum yield, and fluorescence decay time measurements indicate that TFB does not affect the optical properties of the aryl‐F8, which is the emitting material in these devices. Luminance efficiency of up to ≈11 cd A −1 and EQE values of 5.7% are achieved in these structures with the aid of improved out‐coupling using index‐matched hemispheres.
MEMS capacitive pressure sensor monolithically integrated with CMOS readout circuit by using post CMOS processes (2017)

In this paper, we presents a MEMS pressure sensor integrated with a readout circuit on a chip for an on-chip signal processing. The capacitive pressure sensor is formed on a CMOS chip by using a post-CMOS MEMS processes. The proposed device consists of a sensing capacitor that is square in shape, a reference capacitor and a readout circuitry based on a switched-capacitor scheme to detect capacitance change at various environmental pressures. The readout circuit was implemented by using a commercial 0.35 μm CMOS process with 2 polysilicon and 4 metal layers. Then, the pressure sensor was formed by wet etching of metal 2 layer through via hole structures. Experimental results show that the MEMS pressure sensor has a sensitivity of 11 mV/100 kPa at the pressure range of 100–400 kPa.
Surface-Functionalized MWNTs with Emeraldine Base: Preparation and Improving Dielectric Properties of Polymer Nanocomposites (2011)

A comparative study of the dielectric properties of poly(vinylidene fluoride) (PVDF) based nanocomposites with pristine multiwalled carbon nanotubes (MWNTs) and surface-modified MWNTs with core/shell structure (denoted as MEB) as fillers, was reported. Compared with MWNTs/PVDF composites, the MEB/PVDF composites exhibited lower loss tangent and higher dielectric permittivity. It is suggested that the conductive/nonconducting core/shell structure of the MEB filler is the main cause of the improved dielectric properties. Percolation based MWNTs networks is in charge of the improvement of dielectric permittivity, and the nonconducting emeraldine base layer of the MEB filler supports the low loss tangent and low conductivity in the MEB/PVDF composites.
Integration of wide area DGPS with local area kinematic DGPS (2002)

The Stanford University wide area DGPS network has provided a test bed for the development and evaluation of wide area augmentation system (WAAS) algorithms. Until recently, the accuracy performance of these algorithms was assessed only for static users and users on the ground. The only truth models available relied on the user being at a known location or on a surveyed runway. To remedy this situation, the WAAS system was integrated with the integrity beacon landing system (IBLS). IBLS is a local area kinematic DGPS system capable of providing centimeter-level positioning accuracy. The accurate trajectories provided by IBLS are used to assess WAAS performance in an airborne environment. The integration was achieved by porting both the IBLS user software and the WAAS user software to a real-time multi-processing operating system. Both systems now run simultaneously as separate processes on a single computer. The processes can communicate with each other for real-time comparison. They also store data to allow more detailed evaluation in post-processing. Results of flight tests of the Stanford WAAS network are presented.
Development of Multimodal Analgesia Pathways in Outpatient Thyroid and Parathyroid Surgery and Association With Postoperative Opioid Prescription Patterns (2018)

Adoption and adherence to the MMA protocol increased substantially over the study period for patients undergoing thyroid and parathyroid surgery and was associated with a simultaneous significant decline in prescription of postoperative opioid analgesics. Use of nonopioid multimodal agents, incorporating NSAIDs, was safe and did not lead to increased incidence of bleeding. Availability of effective nonopioid MMA pathways may favorably influence physician prescribing practices and avoid unnecessary opioid prescriptions.
High availability of databases for cloud (2015)

In current cyber age, almost all the services are being provided to users over the cloud. Many of these services need to be highly available. Since these services require databases, the databases themselves must be made highly available. Redundancy is the technique of doing this. For this purpose Remus and its adaptation RemusDB use complete virtual machine migration to a backup host which is completely transparent to DBMS. This approach incurs a lot of overhead as the amount of data transferred to the backup host is large and this transfer is done very frequently. Another system Postgres-R works only with PostgreSQL databases. This system replicates data without taking into account the number of requests for a particular table and the load on the servers. In this paper we proposed a solution which is based on another existing system Threshold Based File Replication (TBFR) and uses the current system load to achieve load distribution.
FreshDiskANN: A Fast and Accurate Graph-Based ANN Index for Streaming Similarity Search (2021)

Approximate nearest neighbor search (ANNS) is a fundamental building block in information retrieval with graph-based indices being the current state-of-the-art and widely used in the industry. Recent advances in graph-based indices have made it possible to index and search billion-point datasets with high recall and millisecond-level latency on a single commodity machine with an SSD. However, existing graph algorithms for ANNS support only static indices that cannot reflect real-time changes to the corpus required by many key real-world scenarios (e.g. index of sentences in documents, email, or a news index). To overcome this drawback, the current industry practice for manifesting updates into such indices is to periodically re-build these indices, which can be prohibitively expensive. In this paper, we present the first graph-based ANNS index that reflects corpus updates into the index in real-time without compromising on search performance. Using update rules for this index, we design FreshDiskANN, a system that can index over a billion points on a workstation with an SSD and limited memory, and support thousands of concurrent real-time inserts, deletes and searches per second each, while retaining $>95\%$ 5-recall@5. This represents a 5-10x reduction in the cost of maintaining freshness in indices when compared to existing methods.
Hydrostatic Horizontal Cell (2012)

A new type of cell (Hydrostatic horizontal cell (HHC)) developed for continuous electroplating of strip is described. The cell consists of upper frame, lower frame, upper anode, lower anode, liquid baffle, conductive roll, backup roll, edge mask and its control system etc. The upper and lower hydrostatic cavities are located at the middle of the cell. The HHC adopts an innovative operating principle to generate strong capability of using hydrostatic pressure to grip the strip and to correct the strip twist. It thereby remarkably decreases the running space height and the deviation-from-center error of the strip in the cell. It originally builds up the horizontal spray of electrolyte to both directions at the center of the cell. Consequently the gas exhausting ability of the cell and the electroplating efficiency are improved. The cell has improved overall technical performances over conventional horizontal cells, and it is capable to effectively prevent short circuiting between the strip and the anodes. In general, the advantages of HHC include stable operation, excellent coating quality, high current density, low power consumption, and simple as well as compact equipment.
Fast eye localization from thermal images using neural networks (2016)

Abstract The paper presents a fast algorithm for eye localization from thermal images. Due to blurred edges, lower quality of thermal images compared with visible-light images, the process may be more complicated. On the other hand, it seems relatively easy to designate specific areas of the eyes because of their relatively highest brightness resulting from the highest temperature in these face areas. It turns out, however, that the highest pixel brightness does not always determine unequivocally the position of the eyes. Therefore, the algorithm described here proposes a specialized method for segmentation of images containing eye areas and a specialized classifier. The first part of the algorithm is a block for generating features describing eye areas. The second stage is a decision block built based on a neural network allowing for effective classification of pre-designated areas. A suitable combination of these blocks into a single system allowed for correct analysis of images with rich geometric diversity (scale, position, orientation) and brightness distribution, reaching more than 91 % of correct localizations and time of analysis of a single image of hundredths of a second. Algorithms of this type can be used as the initial stages of facial recognition, emotion recognition, quantitative analysis of the face or modern human-computer interfaces. The described algorithm may be used for both conventional thermal images and thermograms (after prior conversion of temperature values into brightness values), which affects its potential application in medicine. The benefits of this study are twofold: fast localization of characteristic points of the eyes and the possibility of processing despite the typical problems of thermovision and image transformations.
Non-Parametric Modeling of Partially Ranked Data (2007)

Statistical models on full and partial rankings of n items are often of limited practical use for large n due to computational consideration. We explore the use of non-parametric models for partially ranked data and derive efficient procedures for their use for large n. The derivations are largely possible through combinatorial and algebraic manipulations based on the lattice of partial rankings. In particular, we demonstrate for the first time a non-parametric coherent and consistent model capable of efficiently aggregating partially ranked data of different types. 1
FTP4Android: A local/remote file manager for Google Android platform (2011)

Nowadays it is common practice to handle any type of file with the personal computer. The introduction of mobile devices in modern life opened the doors to the possibility to do that ubiquitously, fostering a vast plethora of new entertainment applications. Unfortunately, the storage capacity of these devices is limited; it may hence be useful to have the possibility to store the files on the web and retrieve them at any time and anywhere. To satisfy this need, we have created FTP4Android. Our solution provides smartphone users with the illusion of having an infinite memory on their devices by storing their files on remote servers. To speed up the transfer process both in upload and download, parallel transmissions to/from different servers are performed. To demonstrate how this technology could be used for entertainment purposes, we have devised a treasure hunt application for mobile users based on our FTP4Android.
On generalizing driver gaze zone estimation using convolutional neural networks (2017)

The knowledge of driver distraction will be important for self driving cars in the near future to determine the handoff time to the driver. Driver's gaze direction has been previously shown as an important cue in understanding distraction. While there has been a significant improvement in personalized driver gaze zone estimation systems, a generalized gaze zone estimation system which is invariant to different subjects, perspective and scale is still lagging behind. We take a step towards the generalized system using a Convolutional Neural Network (CNN). For evaluating our system, we collect large naturalistic driving data of 11 drives, driven by 10 subjects in two different cars and label gaze zones for 47515 frames. We train our CNN on 7 subjects and test on the other 3 subjects. Our best performing model achieves an accuracy of 93.36% showing good generalization capability.
Variant translocation of the bcl-2 gene to immunoglobulin lambda light chain gene in chronic lymphocytic leukemia. (1989)

The bcl-2 gene has been identified as a gene directly involved in the consistent chromosome translocation t(14;18), which is found in approximately 90% of human follicular lymphoma cases, and is a prime candidate for the oncogene playing a crucial role in follicular lymphomagenesis. In this paper, we describe a case of chronic lymphocytic leukemia showing the juxtaposition of the bcl-2 gene on chromosome 18 to immunoglobulin lambda light chain (Ig lambda) gene on chromosome 22 in a head-to-head configuration. Sequencing analysis of the joining site of the bcl-2 gene and Ig lambda gene has shown that the breakpoint is within the 5' flanking region of the bcl-2 gene and about 2.2 kilobases 5' to the joining segment of Ig lambda locus in a germ-line configuration. The extranucleotide, commonly appearing at the joining site of the t(14;18) translocation involving the IgH locus, is absent from the joining site of bcl-2 and Ig lambda. The lack of extranucleotide suggests that the juxtaposition of the bcl-2 and Ig lambda genes occurred during physiological rearrangement of the Ig lambda gene since it has been shown that the rearrangement of the Ig lambda locus is not accompanied by extranucleotides.
A Prototype Performance Analysis for V2V Communications using USRP-based Software Defined Radio Platform (2018)

Autonomous driving is usually recognized as a promising technology to replace human drivers in the near future. To guarantee the safety performance in the daily life scenario, multiple-car intelligence with high quality inter-vehicle communication capability is necessary in general. In this paper, to figure out the potential practical issues in the vehicle-to-vehicle transmission, we present a software defined radio platform for V2V communication using universal software radio peripheral (USRP). Based on the LTE framework, we modify the frame structure, the signal processing mechanisms and the resource allocation schemes to emulate the updated LTE-V standard and generate the corresponding numerical results based on the real measured signals. As shown through some empirical studies, three to four dB back-off is in general required to guarantee the reliability performance for V2V communication environments.
Silencing of Phosphonate-Gadolinium Magnetic Resonance Imaging Contrast by Hydroxyapatite Binding (2003)

HA binding assays revealed that GdDOTP5- is essentially MR silent when bound to bone, likely because of the exclusion of all outer sphere water molecules from the surface of the complex. These data suggest a novel strategy for creating highly sensitive, switchable MRI contrast agents.
Human Parsing with Contextualized Convolutional Neural Network (2015)

In this work, we address the human parsing task with a novel Contextualized Convolutional Neural Network (Co-CNN) architecture, which well integrates the cross-layer context, global image-level context, within-super-pixel context and cross-super-pixel neighborhood context into a unified network. Given an input human image, Co-CNN produces the pixel-wise categorization in an end-to-end way. First, the cross-layer context is captured by our basic local-to-global-to-local structure, which hierarchically combines the global semantic structure and the local fine details within the cross-layers. Second, the global image-level label prediction is used as an auxiliary objective in the intermediate layer of the Co-CNN, and its outputs are further used for guiding the feature learning in subsequent convolutional layers to leverage the global image-level context. Finally, to further utilize the local super-pixel contexts, the within-super-pixel smoothing and cross-super-pixel neighbourhood voting are formulated as natural sub-components of the Co-CNN to achieve the local label consistency in both training and testing process. Comprehensive evaluations on two public datasets well demonstrate the significant superiority of our Co-CNN architecture over other state-of-the-arts for human parsing. In particular, the F-1 score on the large dataset [15] reaches 76.95% by Co-CNN, significantly higher than 62.81% and 64.38% by the state-of-the-art algorithms, M-CNN [21] and ATR [15], respectively.
Detection of Phosphopeptides by Localized Surface Plasma Resonance of Titania-Coated Gold Nanoparticles Immobilized on Glass Substrates (2006)

We herein demonstrate a new sensing method for phosphopeptides by localized surface plasmon resonance (LSPR) using titania-coated gold nanoparticles immobilized on the surface of a glass slide as the sensing substrate and using UV-visible spectrophotometry as the detection tool. Titania has been known to be an effective substrate for binding with phosphorylated species. The detection principle is the shift of wavelength of optical absorption due to SPR of the gold nanoparticles induced by binding of phosphorylated species with titania on the surface of the gold nanoparticles. The feasibility of the approach is demonstrated by detection of tryptic digest products of beta-casein and milk. Gold nanoparticles coated with thin films of titania, immobilized on a glass slide, can selectively bind traces of phosphopeptides from complex samples, resulting in a wavelength shift of the absorption band in the SPR spectrum with good reproducibility. The LSPR results are confirmed by matrix-assisted laser desorption/ionization mass spectrometry. The detection limit for the tryptic digest product of beta-casein is 50 nM.
Mapping Functions in Gaze Tracking (2011)

Eye gaze is one of the powerful modes for interaction with the computer. Gaze estimation systems compute the direction of eye gaze. The gaze region on the screen determines the focus and attention of an individual. The gaze tracking systems consists of two major functionalities, feature extraction and determination of gaze mapping functions. The features are the parameters that characterize the pupil and the iris. The gaze mapping functions determine the coordinates on the screen based on interpolation or approximation. In this paper, an in depth analysis of mapping functions is dealt. An attempt has been made to understand the literature of gaze tracking systems.
Cooling by convection vs cooling by conduction for treatment of fever in critically ill adults (2001)

In critically ill adults with an infection or a suspected infection, cooling with an airflow blanket is more effective and more preferred for cooling than is cooling with a water-flow blanket.
Astrue v. Ratliff and the Death of Strong Purposivism (2011)

According to conventional wisdom, the Supreme Court is presently embroiled in an interpretive conflict between textualists, on the one hand, who believe that “the Constitution, properly understood, requires judges to treat the clear import of an enacted text as conclusive, even when the text fits poorly with its apparent background purposes,” 1 and purposivists (or more precisely, “strong purposivists”), on the other, who believe that “the ‘letter’ (text) of a statute must yield to its ‘spirit’ (purpose) when the two conflict[].” This apparent philosophical divide has led one scholar to remark that “textualism has never taken hold as the Court’s single, controlling interpretive method,” and further, that “interpretive consensus” among the Justices “seem[s] impossible.” At first glance, Astrue v. Ratliff, 6

Structure and inhibition of the SARS-CoV-2 main protease reveal strategy for developing dual inhibitors against M <sup>pro</sup> and cathepsin L (2020)

The main protease (M<sup>pro</sup>) of SARS-CoV-2 is a key antiviral drug target. While most M<sup>pro</sup> inhibitors have a γ-lactam glutamine surrogate at the P1 position, we recently found that several M<sup>pro</sup> inhibitors have hydrophobic moieties at the P1 site, including calpain inhibitors II and XII, which are also active against human cathepsin L, a host protease that is important for viral entry. In this study, we solved x-ray crystal structures of M<sup>pro</sup> in complex with calpain inhibitors II and XII and three analogs of <b>GC-376</b> The structure of M<sup>pro</sup> with calpain inhibitor II confirmed that the S1 pocket can accommodate a hydrophobic methionine side chain, challenging the idea that a hydrophilic residue is necessary at this position. The structure of calpain inhibitor XII revealed an unexpected, inverted binding pose. Together, the biochemical, computational, structural, and cellular data presented herein provide new directions for the development of dual inhibitors as SARS-CoV-2 antivirals.
A new method for the reduction of crosstalk and echo in multiconductor interconnections (2005)

Crosstalk and echo can be reduced in multiconductor interconnections, using (truly) matched terminations and a different modal variable for each transmission channel. We first study a conventional technique for reducing reflections, using grounded linear two-terminal circuit elements. Using the concepts of modal voltages and modal currents, we define a new method for the reduction of crosstalk and echo, which involves specific terminations, specific transmitting circuits to send signals, and specific receiving circuits to receive signals. We establish the design equations and show that the new method is related to a particular choice of eigenvectors, called associated eigenvectors. Simulations of two examples of implementation of this method confirm that it provides reduced crosstalk and echo. We also discuss the implementation of the new method with an interconnection having identical propagation constants for all modes. Finally, we compare the new method with a different concept based on modal variables and unspecified terminations.
