Similarity search in multimedia databases (2005)

The research on multimedia databases involves different areas in Computer Science, such as computer graphics, databases, and information retrieval. There are many practical applications that benefit from this research, e.g., molecular biology, medicine, CAD/CAM, and geography. An important characteristic of these applications is the variety of data that should be supported, e.g., text, images (both still and moving), and audio. This implies that the development of a multimedia information system is considerably more complex than a traditional information system. An important research issue in the field of multimedia databases is the content-based retrieval of similar objects. Given a multimedia query object, the search for an exact match in a database is not meaningful in most applications, because the probability that two multimedia objects are identical is negligible (unless they are digital copies from the same source). For this reason, the development of efficient and effective similarity search techniques has become an important topic in the multimedia database research community. The goal of this advanced technology seminar is to provide an overview of the similarity search problem and to present the state-of-art techniques for performing efficient and effective similarity queries in multimedia databases. The seminar begins with an introduction and a motivation of multimedia databases. The two main approaches for describing multimedia objects (as elements in a metric space or in a vector space) are introduced, as well as a description of the ”Multimedia Content Description Interface” (MPEG)-7 standard. The efficiency issue is addressed for both metric and vector space approaches, describing the data structures and algorithms used to answer similarity queries. For the effectiveness issue, the seminar introduces some widely used retrieval performance measures. Several examples of techniques for particular multimedia applications (text, image, CAD, 3D objects, audio and video) are presented. The seminar outline is as follows:
Coding Method for Parallel Iterative Linear Solver (2017)

Computationally intensive distributed and parallel computing is often bottlenecked by a small set of slow workers known as stragglers. In this paper, we utilize the emerging idea of "coded computation" to design a novel error-correcting-code inspired technique for solving linear inverse problems under specific iterative methods in a parallelized implementation affected by stragglers. Example applications include inverse problems in machine learning on graphs, such as personalized PageRank and sampling on graphs. We provably show that our coded-computation technique can reduce the mean-squared error under a computational deadline constraint. In fact, the ratio of mean-squared error of replication-based and coded techniques diverges to infinity as the deadline increases. Our experiments for personalized PageRank performed on real systems and real social networks show that this ratio can be as large as $10^4$. Further, unlike coded-computation techniques proposed thus far, our strategy combines outputs of all workers, including the stragglers, to produce more accurate estimates at the computational deadline. This also ensures that the accuracy degrades "gracefully" in the event that the number of stragglers is large.
CMOS integrated system for magnetic field monitoring and gradient measurement in MRI environment (2007)

This paper reports on a standard CMOS integrated system for monitoring the magnetic fields in MRI environments. The sub-micron technology circuit features three horizontal hall devices and their associated electronics that form instrumental chains. Two of them are dedicated to millitesla range magnetic pulse and gradient measurement whereas the third one is for monitoring the strong static field of the MRI setup. The 0.35 mum technology prototype performs 130 muT gradient measurement with 20 muT resolution and can also map static fields as high as 1.5T.
Application of Newly Developed Amniotic Membrane Ointment for Photorefractive Keratectomy in Rabbits (2005)

We developed amniotic membrane ointment (AMO), and the effect of instilling the AMO after photorefractive keratectomy (PRK) was investigated with respect to inflammatory cell infiltration into the corneal stroma, apoptosis of keratocytes, and suppression of lipid peroxidation of cellular walls. The PRK procedure was performed on both eyes of 10 white rabbits. One eye of each rabbit (the experimental eye) was instilled with the AMO and the other eye of the rabbit (the control eye) with a base ointment 0, 8 and 16 h after the PRK procedure. Corneal specimens were collected 24 h after the PRK procedure. Hematoxylin-eosin stain and TUNEL assay were conducted to demonstrate polymorphonuclear and apoptotic cells, respectively. To assess lipid peroxidation, immunohistochemical staining with an antibody to malondialdehyde was undertaken. Compared to the control, the cornea instilled with the AMO had significantly less polymorphonuclear cells infiltrating into the corneal stroma as well as keratocytes subjected to apoptosis. These corneas also showed a significantly less extent of lipid peroxidation than the control. These data support that instillation of the AMO effectively reduced the recruitment of polymorphonuclear cells, the induction of apoptosis in keratocytes, and lipid peroxidation induced by PRK. Thus, this study could provide basic data on the clinical application of the AMO in the days ahead.
Investigations Into the Linear Coupling Between Symmetric and Anti-Symmetric Modes of V-Shaped MEMS Resonators Under Electrostatic Perturbation (2021)

Abstract In this paper, we investigate experimentally and theoretically the linear coupling between the first two symmetric and anti-symmetric modes of an electrothermally and electrostatically actuated in-plane V-shaped micro-beam. The micro-beam is fabricated from highly doped silicon and is sandwiched between four electrodes to electrostatically activate both modes of vibrations. When tuning the electrothermal voltage, the natural frequencies of the two modes approach each other until they cross. Under electrostatic actuation, it is shown experimentally that the system undergoes a transition between modes crossing to veering. In addition, an analytical study is presented based on a Galerkin-based reduced-order model of a nonlinear Euler–Bernoulli shallow arch beam equation. The analytical results are compared to experimental data showing excellent agreement.
Bridging East and West: Muslim‐identified activists and organisations in the UK anti‐war movements (2009)

Divisive Orientalist discourses and practices, mobilised in the ‘war on terror’, have been resisted through collaborative political projects designed to contest and close gaps between East and West, Muslim and non‐Muslim. Through interviews with Muslim‐identified and other British anti‐war activists, this paper traces the making of a ‘new bridge between the East and the West’. It then goes on to examine the limitations of this political model and describe the search for political relationships that would mobilise Muslim identities in more subtle ways and speak past rather than against contemporary Orientalism.
VEGF ‐ A regulated by progesterone governs uterine angiogenesis and vascular remodelling during pregnancy (2013)

The features and regulation of uterine angiogenesis and vascular remodelling during pregnancy are poorly defined. Here we show that dynamic and variable decidual angiogenesis (sprouting, intussusception and networking), and active vigorous vascular remodelling such as enlargement and elongation of 'vascular sinus folding' (VSF) and mural cell drop-out occur distinctly in a spatiotemporal manner in the rapidly growing mouse uterus during early pregnancy - just after implantation but before placentation. Decidual angiogenesis is mainly regulated through VEGF-A secreted from the progesterone receptor (PR)-expressing decidual stromal cells which are largely distributed in the anti-mesometrial region (AMR). In comparison, P4 -PR-regulated VEGF-A-VEGFR2 signalling, ligand-independent VEGFR3 signalling and uterine natural killer (uNK) cells positively and coordinately regulate enlargement and elongation of VSF. During the postpartum period, Tie2 signalling could be involved in vascular maturation at the endometrium in a ligand-independent manner, with marked reduction of VEGF-A, VEGFR2 and PR expressions. Overall, we show that two key vascular growth factor receptors - VEGFR2 and Tie2 - strikingly but differentially regulate decidual angiogenesis and vascular remodelling in rapidly growing and regressing uteri in an organotypic manner.
Accurate TLS Fingerprinting using Destination Context and Knowledge Bases (2020)

Network fingerprinting is used to identify applications, provide insight into network traffic, and detect malicious activity. With the broad adoption of TLS, traditional fingerprinting techniques that rely on clear-text data are no longer viable. TLS-specific techniques have been introduced that create a fingerprint string from carefully selected data features in the client_hello to facilitate process identification before data is exchanged. Unfortunately, this approach fails in practice because hundreds of processes can map to the same fingerprint string. We solve this problem by presenting a TLS fingerprinting system that makes use of the destination address, port, and server name in addition to a carefully constructed fingerprint string. The destination context is used to disambiguate the set of processes that match a fingerprint string by applying a weighted naive Bayes classifier, resulting in far greater performance.
Search for Squarks and Gluinos in Events Containing Jets and a Large Imbalance in Transverse Energy (1999)

Using data corresponding to an integrated luminosity of $79{\mathrm{pb}}^{\ensuremath{-}1}$, D0 has searched for events containing multiple jets and large missing transverse energy in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\phantom{\rule{0ex}{0ex}}\mathrm{TeV}$ at the Fermilab Tevatron collider. Observing no significant excess beyond what is expected from the standard model, we set limits on the masses of squarks and gluinos and on the model parameters ${m}_{0}$ and ${m}_{1/2}$, in the framework of the minimal low-energy supergravity models of supersymmetry. For $\mathrm{tan}\ensuremath{\beta}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2$ and ${A}_{0}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$, with $\ensuremath{\mu}&lt;0$, we exclude all models with ${m}_{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{q}}&lt;250\phantom{\rule{0ex}{0ex}}\mathrm{GeV}{/c}^{2}$. For models with equal squark and gluino masses, we exclude $m&lt;260\phantom{\rule{0ex}{0ex}}\mathrm{GeV}{/c}^{2}$.
A 2.7-GHz multi-level PWM carrier-bursting RF transmitter (2015)

Carrier-bursting is an attractive RF transmitter concept to achieve high efficiency. The power amplifier (PA) itself either operates at its peak efficiency or is turned off. Another efficiency-enhancing approach is the Doherty concept, where the main PA reaches its peak efficiency already in back-off and the peak PA contributes at high input levels to reach the desired output power. In this work, we attempt to combine the best of both concepts and derive a two-level dual-output pulse width modulator driving two PAs whose outputs are combined. We have evaluated the concept by a real-time FPGA implementation of the modulator for a 2.7GHz carrier driving two Class-AB PAs with a combined peak output power of 30W. The approach exhibits a potentially more pronounced back-off efficiency peak compared to the Doherty concept. Furthermore, the overall efficiency scales with the drain efficiency of the PAs and can thus be improved by employing Class-D or Class-F PAs.
Towards Scaleable and Adaptive Document Routing Services (2006)

We propose a framework for intelligent document routing that extends XML technologies and enables realtime update of business routing logic. A novel feature of our system is the ability to semi-automate the process of creating and updating the routing rules. This is achieved by a closed loop system that performs clustering and inductive rule learning of document features. This framework was tested and deployed in a large real-world enterprise environment resulting in reduced development costs and simplified administration. The user interacts with the system using an application to graphically create, edit and publish the business processes
Feasibility, acceptability, and adoption of fingerprint scanning during contact investigation for tuberculosis in Kampala, Uganda: A parallel-convergent, mixed-methods analysis (2018)

Background: In resource-constrained settings, challenges with unique patient identification may limit continuity of care, monitoring and evaluation, and data integrity. Biometrics offer an appealing but understudied potential solution. Methods: We conducted a mixed-methods study to understand feasibility, acceptability, and adoption of digital fingerprinting for patient identification in a study of household TB contact investigation in Kampala, Uganda. We tested associations between demographic, clinical, and temporal characteristics and failure to capture a digital fingerprint. We used generalized estimating equations and a robust covariance estimator to account for clustering. We evaluated clustering of outcomes by household and community health worker by calculating intra-class correlation coefficients. To understand determinants of intended and actual use of fingerprinting technology, we conducted fifteen in-depth interviews with community health workers and applied a widely used conceptual framework, the Technology Acceptance Model 2. Results: Digital fingerprints were captured in 74% of participants, with extensive clustering by household (ICC = 0.99) arising from hardware (36%) and software (60%) failures. Clinical and demographic characteristics were not significantly associated with fingerprint capture. Community health workers successfully fingerprinted all contacts in 70% of households, with modest clustering of outcomes by CHW (ICC = 0.18). Fingerprinting success at the household level declined over time (Spearman’s rho = 0.30, P &lt; 0.001). In interviews, CHWs reported that fingerprinting non-capture events lowered their own perception of the quality of the technology, threatened their social image, and made the technology more difficult to use. Conclusions: We found digital fingerprinting to be feasible and acceptable for indvidual identification, but problems implementing the hardware and software led to a high failure rate. Although CHWs found fingerprinting to be acceptable in principle, their intention to use the technology was tempered by perceptions that it was inconsistent and of questionable value. We emphasize the need for routine process evaluation of biometrics and other digital technologies during implementation in resource-constrained settings.
MULTIPLEXED VIABILITY, CYTOTOXICITY AND APOPTOSIS ASSAYS FOR CELL-BASED SCREENING (2006)

Recent advances in combinatorial synthesis chemistries have led to both larger and more focused libraries of new chemical entities. The challenge continues to be testing these compounds for biological effects while maintaining cost economy. Although increasing throughput has helped efficiency, a number of factors shape the quality of the data derived from a screen. Ultimately, this quality dictates the probability of identifying active compounds worthy of further characterization.
Preferred Orientation Evolution of Hole Transport Materials for High Emitting Dipole Orientation Ratio of the Emitting Material (2022)

Abstract Control of the molecular orientation is an effective approach to enhance the performance of organic light‐emitting diodes. This study examines the molecular dipole orientation of hole transport materials depending on the deposition step and the consecutive effect on the transition dipole orientation of the emitting dopant. In contrast to other reference materials, 4,4′,4′′‐tris(carbazole‐9‐yl)triphenylamine (TCTA) shows a preferred orientation only in the continuously deposited films that is dependent on the film thickness. The horizontal dipole orientation ratio of the emitting dopant deposited on the TCTA is improved by the alignment of TCTA molecules. The power efficiency of the device produced from the above materials is increased from 28.9 to 34.4 lm W −1 owing to the dual enhancement of the hole mobility of TCTA and the horizontal dipole orientation ratio of the emitting dopant. The molecular orientation of the charge transport layer contributes to charge transport in the layer and the molecular orientation of the adjacent emitting layer.
Improving thermal stability and efficacy of BCNU in treating glioma cells using PAA-functionalized graphene oxide (2012)

Nanosized PAA-GO serves as an efficient BCNU nanocarrier by covalent binding. This nanocarrier will be a promising new vehicle for an advanced drug delivery system in cancer therapy.
Pancreatic Cancer Database (2014)

Pancreatic cancer is the fourth leading cause of cancer-related death in the world. The etiology of pancreatic cancer is heterogeneous with a wide range of alterations that have already been reported at the level of the genome, transcriptome, and proteome. The past decade has witnessed a large number of experimental studies using high-throughput technology platforms to identify genes whose expression at the transcript or protein levels is altered in pancreatic cancer. Based on expression studies, a number of molecules have also been proposed as potential biomarkers for diagnosis and prognosis of this deadly cancer. Currently, there are no repositories which provide an integrative view of multiple Omics data sets from published research on pancreatic cancer. Here, we describe the development of a web-based resource, Pancreatic Cancer Database (http://www.pancreaticcancerdatabase.org), as a unified platform for pancreatic cancer research. PCD contains manually curated information pertaining to quantitative alterations in miRNA, mRNA, and proteins obtained from small-scale as well as high-throughput studies of pancreatic cancer tissues and cell lines. We believe that PCD will serve as an integrative platform for scientific community involved in pancreatic cancer research.
DIRECT INHIBITION OF TESTICULAR ANDROGEN BIOSYNTHESIS BY ARGININE-VASOPRESSIN: THROUGH PRESSOR-SELECTIVE TESTICULAR RECOGNITION SITES (1981)

We have observed that arginine vasopressin (AVP) and related neurohypophysial hormones exert direct inhibition of testicular androgen biosynthesis in vitro. In this report, the functional identity of the putative testicular recognition sites mediating the antigonadal activity of the neurohypophysial hormones was investigated. Pressor-selective (but not antidiuretic- or oxytocic-selective) agonists of neurohypophysial hormones exerted a dose-dependent inhibition of the hCG-stimulated accumulation of testosterone by cultured rat testicular cells. In addition, potent pressor (but not oxytocic) antagonists brought about a dose-dependent blockage of the AVP-induced inhibition of testicular androgen biosynthesis. Thus, the antigonadal activity of neurohypophysial hormones is mediated by specific testicular recognition sites similar to those mediating the pressor actions of these neuropeptides but distinct from those involved in their antidiuretic or oxytocic effects.
Measuring, modeling, and decoupling of saturation-induced saliencies in carrier-signal injection-based sensorless AC drives (2001)

The focus of this paper is the measuring, modeling, and decoupling of saturation-induced saliencies in carrier-signal injection-based sensorless control. First, techniques for the measurement of saturation-induced saliencies are presented. The goal of these measurements is to provide useful information on the position and magnitude of the various saturation-induced saliencies. Using the results from several different experimental measurements, models are developed explaining the source and behavior of the saturation-induced saliencies. The paper concludes by presenting methods for decoupling the effects caused by the parasitic saturation-induced saliencies, eliminating the errors that they cause in rotor position or flux angle estimation.
A design procedure for an acoustic mirror providing dual reflection of longitudinal and shear waves in Solidly Mounted BAW Resonators (SMRs) (2009)

The quality factor of the traditional Solidly Mounted Resonator (SMR) is limited by substrate losses, as the traditionally employed acoustic mirror reflects longitudinal waves but not shear waves. Modern mirrors do reflect both waves, but design rules for such mirrors have not been published so far. We propose a systematic design procedure derived from optics leading to a novel embodiment for the acoustic mirror which effectively reflects both longitudinal and shear waves. This method can be applied for the acoustic mirror design for any given material combination. An analytical model is presented; its agreement with FEM simulations is good. With the optimized design, we can obtain a minimum transmission for longitudinal and shear waves of -25 dB and -20 dB at resonance frequencies for longitudinal and shear waves, respectively, for various reflector material combinations.
Faceted identity, faceted lives (2011)

This paper explores key issues people experience managing personal boundaries within and across social technologies. We look in particular at email and online social networks. We offer a theoretical framework for understanding the errors in assumptions about the singularity of identity that are currently inscribed into the sharing models of social technology systems. Through a questionnaire study we examine how people facet their identities and their lives, and how these facets are expressed through use of email and Facebook. We found family was an extremely important context for sharing online, and that email was still a preferred form of communication for private sharing across facets of life. Single, working men had the highest level of incompatible facets, and a higher level of facet incompatibility was correlated with increased email usage and worry about sharing in the context of social networks.
Holes in the Glycan Shield of the Native HIV Envelope Are a Target of Trimer-Elicited Neutralizing Antibodies (2016)

A major advance in the search for an HIV vaccine has been the development of a near-native Envelope trimer (BG505 SOSIP.664) that can induce robust autologous Tier 2 neutralization. Here, potently neutralizing monoclonal antibodies (nAbs) from rabbits immunized with BG505 SOSIP.664 are shown to recognize an immunodominant region of gp120 centered on residue 241. Residue 241 occupies a hole in the glycan defenses of the BG505 isolate, with fewer than 3% of global isolates lacking a glycan site at this position. However, at least one conserved glycan site is missing in 89% of viruses, suggesting the presence of glycan holes in most HIV isolates. Serum evidence is consistent with targeting of holes in natural infection. The immunogenic nature of breaches in the glycan shield has been under-appreciated in previous attempts to understand autologous neutralizing antibody responses and has important potential consequences for HIV vaccine design.
