A Survey of Appearance Models in Visual Object Tracking (2013)

Visual object tracking is a significant computer vision task which can be applied to many domains such as visual surveillance, human computer interaction, and video compression. In the literature, researchers have proposed a variety of 2D appearance models. To help readers swiftly learn the recent advances in 2D appearance models for visual object tracking, we contribute this survey, which provides a detailed review of the existing 2D appearance models. In particular, this survey takes a module-based architecture that enables readers to easily grasp the key points of visual object tracking. In this survey, we first decompose the problem of appearance modeling into two different processing stages: visual representation and statistical modeling. Then, different 2D appearance models are categorized and discussed with respect to their composition modules. Finally, we address several issues of interest as well as the remaining challenges for future research on this topic. The contributions of this survey are four-fold. First, we review the literature of visual representations according to their feature-construction mechanisms (i.e., local and global). Second, the existing statistical modeling schemes for tracking-by-detection are reviewed according to their model-construction mechanisms: generative, discriminative, and hybrid generative-discriminative. Third, each type of visual representations or statistical modeling techniques is analyzed and discussed from a theoretical or practical viewpoint. Fourth, the existing benchmark resources (e.g., source code and video datasets) are examined in this survey.
Weak inversion four-quadrant multiplier and two-quadrantdivider (1998)

A four-quadrant multiplier and a two-quadrant divider are presented. The proposed circuits are implemented by MOSFETs operating in weak inversion and are therefore suitable for low voltage and low power applications. Their performances were confirmed by HSPICE simulation using a 0.8 µm CMOS process. The multiplier can operate under a ±0.75 V supply voltage and its linear input range is ~0.125 µA with error < 2%. The input range of the divider is 0.5 – 2 µA and the error is < 3% for divider current < 60 nA.
Size-Based Protein Separations in Poly(ethylene glycol)-Derivatized Gold Nanotubule Membranes (2001)

An electroless plating method was used to deposit Au nanotubules within the pores of track-etched polycarbonate template membranes. The effect of nanotubule inside diameter on rate and selectivity of protein transport was investigated for three proteins: lysozyme (Lys), bovine serum albumin (BSA), and β-lactoglobulin A. Transport selectivity increased as the inside diameter of the nanotubules within the membrane decreased, and selectivity coefficients in excess of 20 were observed for the separation of Lys from BSA. Protein adsorption, and hence membrane fouling, was eliminated by chemisorbing a poly(ethylene glycol) thiol to the Au nanotubule membranes.

Genetic analysis of Staphylococcus aureus RNA polymerase mutants (1979)

Spontaneous mutants of Staphylococcus aureus resistant to rifampin, rifamycin SV, streptovaricin, or streptolydigin were isolated and shown to be resistant due to chromosomal rather than plasmid mutations. Based on data concerning spontaneous mutation rates, genetic cotransduction rates, and in vitro sensitivity studies, four major antibiotic cross-resistance patterns were found. The genetic markers responsible for these cross-resistance patterns were shown to be separable by transduction. Nonpurified RNA polymerase activity in lysates of mutants showed the same sensitivity to these antibiotics as shown by the mutants on solid media. A model is proposed explaining possible structure-function relationships involved in the binding of these antibiotics to the RNA polymerase molecule and the mutations resulting in resistance to these antibiotics. This model includes generally overlapping but different-sized binding sites on the RNA polymerase protein coded for by similarly arranged mutable sites on the DNA.
Projection optical lithography (2005)

Projection optical lithography has had a remarkable history and, most probably, it will have an equally successful future for at least another decade. To date, it has met all the major challenges posed by the semiconductor industry roadmap. In order to do so, it has undergone important transformations, and has greatly expanded the frontiers of the science and engineering of optics. This paper will review the most recent developments, including transitioning to the short wavelengths of 193 nm and 157 nm, moving toward ultrahigh numerical apertures facilitated by liquid immersion, and incorporation of a range of resolution-enhancing techniques such as optical proximity correction and phase-shifting masks.
Optimisation of a grating device for coupling radiation in and out of a thin-film waveguide on a silicon substrate (1994)

An analysis is reported of the operation and optimisation of the parameters of a grating device for coupling radiation in and out of a thin-film waveguide formed on a silicon substrate. The reflection of light at the interface between a buffer layer and silicon significantly alters the operation of such a grating coupler. The conditions for maximum coupling out of radiation into air or into the substrate are obtained for the TE and TM modes of the thin-film waveguide.

Magic Surfaces: A Smart Building Material for Indoor Sensing Infrastructures (2007)

In this paper, we introduce magic surfaces; a novel positioning and networking infrastructure for indoor sensor network applications. To support various kinds of applications, magic surfaces provide positioning, orientation estimation, bidirectional communication and power transmission functions in a contact-less manner by using a magnetic-based technique. This paper describes the design, implementation and performance evaluations of magic surfaces.
All-Optical Continuously Tunable Flat-Passband Microwave Photonic Notch Filter (2015)

A new all-optical microwave photonic notch filter (MPNF) is presented. It is based on controlling the amplitude and phase of the optical carriers and RF phase modulation sidebands via a diffraction-based Fourier-domain optical processor. It has the ability of realizing a flat-passband, narrow-notch, and large-free-spectral-range amplitude response and a group delay response with very few ripples. The carrier and sideband optical phase controls enable a continuous notch frequency tuning operation to be realized without altering the response shape. The filter has a simple structure and a wide bandwidth as it only involves optical components. Experimental results demonstrate an MPNF that exhibits a flat passband with <; 1 dB ripples, a deep notch of > 35 dB, and low group delay ripples of <; ±25 ps, together with the continuous notch frequency tunability and excellent long-term stability and repeatability.
Methodology for the registration of whole SLO sequences (2003)

Images acquired with the Scanning Laser Ophthalmoscope (SLO) device offer a very good tool for the evaluation of retinal diseases and obtaining interesting haemodynamic variables related to retinal blood flow. But because of the unavoidable eye movements, it is necessary a previous registration process to obtain a reliable analysis of the information extracted from these set of frames. This paper explains an algorithm which allows a fully automatic registration of the whole SLO sequence by combining two registration techniques: a landmark based registration and a mutual information based one. The accurate registration of the frames will allow the automatic calculation of the so called dye dilution curves, which are computed by means of a robust fitting algorithm based on the optimisation method Simulated Annealing. With that curves it will be possible to obtain valuable haemodynamic variables, like the arteriovenous passage time described here.
Über die Totenklage im deutschen Sprachraum (1963)

Die Umsiedlungen im Gefolge des Zweiten Weltkrieges haben die wichtigste Quelle für die Kenntnis des älteren deutschen Volksliedes fast zur Gänze verschüttet. Ich meine jene Melodien, die seit den achtziger Jahren des vorigen Jahrhunderts in deutschen Sprachinseln Süd- und Osteuropas aufgezeichnet werden konnten (Suppan, 1962-63). Heute sind nur noch wenige ergänzende Einzelstücke von ähnlichem Wert und Alter aufzulesen. Von einem solchen Relikt, das die beiden Freiburger Volkskundler J. Künzig und W. Werner 1961 in Süddeutschland auf Tonband festhalten konnten und in dankenswerter Weise dem Referenten zur Verfügung stellten, soll hier die Rede sein: es handelt sich um das Fragment einer siebenbürgisch-sächsischen Totenklage, die der ältesten Schicht zugehört, die bisher in diesem Raum erfasst werden konnte.
A review on the clinical implementation of respiratory-gated radiation therapy (2007)

Respiratory-gated treatment techniques have been introduced into the radiation oncology practice to manage target or organ motions. This paper will review the implementation of this type of gated treatment technique where the respiratory cycle is determined using an external marker. The external marker device is placed on the abdominal region between the xyphoid process and the umbilicus of the patient. An infrared camera tracks the motion of the marker to generate a surrogate for the respiratory cycle. The relationship, if any, between the respiratory cycle and the movement of the target can be complex. The four-dimensional computed tomography (4DCT) scanner is used to identify this motion for those patients that meet three requirements for the successful implementation of respiratory-gated treatment technique for radiation therapy. These requirements are (a) the respiratory cycle must be periodic and maintained during treatment, (b) the movement of the target must be related to the respiratory cycle, and (c) the gating window can be set sufficiently large to minimise the overall treatment time or increase the duty cycle and yet small enough to be within the gate. If the respiratory-gated treatment technique is employed, the end-expiration image set is typically used for treatment planning purposes because this image set represents the phase of the respiratory cycle where the anatomical movement is often the least for the longest time. Contouring should account for tumour residual motion, setup uncertainty, and also allow for deviation from the expected respiratory cycle during treatment. Respiratory-gated intensity-modulated radiation therapy (IMRT) treatment plans must also be validated prior to treatment. Quality assurance should be performed to check for positional changes and the output in association with the motion-gated technique. To avoid potential treatment errors, radiation therapist (radiographer) should be regularly in-serviced and made aware of the need to invoke the gating feature when prescribed for selected patients.
Multicenter Phase II Study of Bendamustine Plus Rituximab in Patients With Relapsed or Refractory Diffuse Large B-Cell Lymphoma (2013)

BR is a promising salvage regimen for patients with relapsed or refractory DLBCL after rituximab-containing chemotherapy, warranting further investigation.
[Comparison of clinical features of childhood and adult onset Still's disease]. (1991)

Physical findings, laboratory data, treatments and prognosis were investigated in detail using 26 Japanese childhood Still's disease (CHSD) patients and 19 Japanese adult onset Still's disease (AOSD) patients as the subjects. High spiking fever and arthritis were present in all the patients. Seventy and seven percent of CHSD and 53 percent of AOSD had polyarthritis (the number of joints involved being 5 or more during the first 6 months of the disease). A comparison of the groups showed no significant difference in the initial systemic manifestations except for sore throat (CHSD: AOSD; 19%: 68%). Initial laboratory data were the same for these groups except for serum iron levels (CHSD: AOSD; 20.8 +/- 13.7 micrograms/dl: 83.0 +/- 54.2 micrograms/dl). As to joints and physical prognosis, the results were also the same for CHSD and AOSD under the similar treatment. On the basis of these data, we conclude that CHSD and AOSD are of the same disease entity so far as the present clinical features are concerned.
A language for end-user web augmentation (2013)

Web augmentation is to the Web what augmented reality is to the physical world: layering relevant content/layout/navigation over the existing Web to customize the user experience. This is achieved through JavaScript (JS) using browser weavers (e.g., Greasemonkey). To date, over 43 million of downloads of Greasemonkey scripts ground the vitality of this movement. However, Web augmentation is hindered by being programming intensive and prone to malware. This prevents end-users from participating as both producers and consumers of scripts: producers need to know JS, consumers need to trust JS. This article aims at promoting end-user participation in both roles. The vision is for end-users to prosume (the act of simultaneously caring for producing and consuming) scripts as easily as they currently prosume their pictures or videos. Encouraging production requires more “natural” and abstract constructs. Promoting consumption calls for augmentation scripts to be easier to understand, share, and trust upon. To this end, we explore the use of Domain-Specific Languages (DSLs) by introducing Sticklet . Sticklet is an internal DSL on JS, where JS generality is reduced for the sake of learnability and reliability. Specifically, Web augmentation is conceived as fixing in existing web sites (i.e., the wall ) HTML fragments extracted from either other sites or Web services (i.e., the stickers ). Sticklet targets hobby programmers as producers, and computer literates as consumers. From a producer perspective, benefits are threefold. As a restricted grammar on top of JS, Sticklet expressions are domain oriented and more declarative than their JS counterparts, hence speeding up development. As syntactically correct JS expressions, Sticklet scripts can be installed as traditional scripts and hence, programmers can continue using existing JS tools. As declarative expressions, they are easier to maintain, and amenable for optimization. From a consumer perspective, domain specificity brings understandability (due to declarativeness), reliability (due to built-in security), and “consumability” (i.e., installation/enactment/sharing of Sticklet expressions are tuned to the shortage of time and skills of the target audience). Preliminary evaluations indicate that 77% of the subjects were able to develop new Sticklet scripts in less than thirty minutes while 84% were able to consume these scripts in less than ten minutes. Sticklet is available to download as a Mozilla add-on.
A Different Kind of Story. Tracing the Histories and Cultural Marks of Pirate Copied Film (2023)

Pirate copied objects are fiery artifacts that have caused much anxiety and debate. This article explores the cultural biographies of one particular type of such objects; digital pirate copied films. More specifically, it traces two neglected aspects of such object’s life histories: their entanglement in systems of standardization and quality control, and the ways in which new types of aesthetics and narratives are inscribed (or added to) pirated audiovisual content. Paying close attention to the layered and multifaceted dimensions of digital pirate copied film, the paper approaches the act of pirate copying as a form of transfiguration, and suggests that pirated objects are much more than plain replications. By housing a multiplicity of material identities and by carrying (and being surrounded by) alternative narratives of production, the article argues that these objects intervene, disorient, and disrupt the power dynamics of cinematic circulation and ultimately serve to queer commodity spheres.
Broadband dispersion compensating fiber using index-guiding photonic crystal fiber with defected core (2008)

We present a novel broadband dispersion compensating photonic crystal fiber with defected core in this paper. The small central defect of air hole can flexibly control the chromatic dispersion properties of this kind of photonic crystal fiber. This kind of fiber has broadband large negative chromatic dispersion, and the chromatic dispersion coefficient varies from -440 to -480 ps/(nm·km) in the measured wavelength range of 1500-1625 nm. The calculated chromatic dispersion curve is well matched to the measured chromatic dispersion coefficient in the range of 1500-1625 nm. The proposed photonic crystal fiber can be used to design the dispersion compensating fiber in the desired wavelength range by adjusting its structural parameters.
Investigation of mammalian lignan precursors in flax seed: First evidence of secoisolariciresinol diglucoside in two isomeric forms by liquid chromatography/mass spectrometry (1994)

A strong research effort has been devoted in recent years to the mammalian lignans enterolactone and enterodiol because of their claimed protective effects against breast and colon cancer. Some plant lignans appear to be precursors of these molecules. This paper reports a novel identification procedure for one of these precursors, the secoisolariciresinol diglucoside, in the extracts of defatted flax-seed meal. The procedure is based on high-performance liquid chromatography coupled with either ionspray or continuous-flow fast-atom bombardment mass spectrometry. The application of these techniques allowed the identification in flax seed of two isomeric forms of this precursor for the first time. The isomers are reasonable the two diastereoisomers, due to the two equivalent stereogenic centers present in the molecule.
Computer Vision Control for Phased Array Beam Steering (2018)

This work proves a concept for a wireless access point that uses image identification and tracking algorithms to automate the electronic control of a phased antenna array. Phased arrays change the direction of their radiation electronically by adjusting the phase of the signal applied to the individual antenna elements of the array. This ability can improve a user’s connectivity to a wireless network by directing radiation from an access point to a user, provided that the user’s location is known. Open source image processing and machine learning libraries provided a basis for developing a Python program that determines the position of a target using a single camera. This program uses the position information acquired from the camera to calculate the phases required to steer the radiation of the array to the target. The Python program sends the required phases to another piece of software that controls the phases of the phased array. This software adjusts the phases of the antenna elements and steers the main beam. Experiments were conducted to evaluate the identification, tracking, and control capabilities of the system. Finally, a full system demonstration was performed to benchmark the wireless performance, study the trade-offs in performance for complexity, and compare the connectivity to the current standard in multi-antenna access points.
Synthesis and Experimental Validation of New PDI Inhibitors with Antiproliferative Activity (2017)

Protein disulfide isomerase (PDI) is a member of the thioredoxin superfamily of redox enzymes. PDI is a multifunctional protein that catalyzes disulfide bond formation, cleavage, and rearrangement in unfolded or misfolded proteins and functions as a chaperone in the endoplasmic reticulum. Besides acting as a protein folding catalyst, several evidences have suggested that PDI can bind small molecules containing, for example, a phenolic structure, which includes the estrogenic one. Increasing studies indicate that PDI is involved in both physiology and pathophysiology of cells and tissues and is involved in the survival and proliferation of different cancers. Propionic acid carbamoyl methyl amides (PACMAs) showed anticancer activity in human ovarian cancer, both in vitro and in vivo, by inhibiting PDI. The inhibition of PDI’s activity may have a therapeutic role, in various diseases, including cancer. In the present study, we designed and synthesized a diversified small library of compounds with the aim of identifying a new class of PDI inhibitors. Most of synthesized compounds showed a good inhibitory potency against PDI and particularly 4-methyl substituted 2,6-di- tert -butylphenol derivatives ( 8–10 ) presented an antiproliferative activity in a wide panel of human cancer cell lines, including ovarian ones.
Three-dimensional nth derivative of Gaussian separable steerable filters (2005)

This paper details the construction of three-dimensional separable steerable filters. The approach presented is an extension of the construction of two-dimensional separable steerable filters outlined in W.T. Freeman and E.H. Adelson (1991). Additionally, three-dimensional separable steerable filters, both continuous and discrete versions, for the second derivative of the Gaussian and its Hilbert transform are reported. Experimental evaluation demonstrates that the errors in the constructed separable filters are negligible.
