Multiple Object Tracking with Mixture Density Networks for Trajectory Estimation (2021)

Multiple object tracking faces several challenges that may be alleviated with trajectory information. Knowing the posterior locations of an object helps disambiguating and solving situations such as occlusions, re-identification, and identity switching. In this work, we show that trajectory estimation can become a key factor for tracking, and present TrajE, a trajectory estimator based on recurrent mixture density networks, as a generic module that can be added to existing object trackers. To provide several trajectory hypotheses, our method uses beam search. Also, relying on the same estimated trajectory, we propose to reconstruct a track after an occlusion occurs. We integrate TrajE into two state of the art tracking algorithms, CenterTrack [63] and Tracktor [3]. Their respective performances in the MOTChallenge 2017 test set are boosted 6.3 and 0.3 points in MOTA score, and 1.8 and 3.1 in IDF1, setting a new state of the art for the CenterTrack+TrajE configuration
Regional pulse volume and perfusion flow measurement: electrical impedance plethysmography. (1998)

Pulse volume and changes in perfusion flow pertaining to a segment such as the arm or leg may easily be followed by radiofrequency impedance plethysmography. Volume varies directly with electrical conductance and inversely as the resistive electrical impedance of the conductor. The method is sketched briefly in Figure 1 and defined in its legend. Thus, we propose by this type of study (1) to measure pulse volume and blood flow on the basis of electrical properties of tissue and blood; (2) to calculate pulse volume and blood flow from such electrical data, and (3) to apply the electrical impedance method to physiological and clinical flow problems. Electrical impedance to radiofrequency current through tissues is capacitative as well as resistive in nature. The former is less than three per cent of the latter in value and may be regarded as insignificant when volume pulses are derived from the limbs. A
Massspectrometrical analysis of recombinant human growth hormone Norditropin® reveals amino acid exchange at M14_V14 rhGH (2005)

Recombinant human growth hormone (rhGH) is used for the treatment of several disorders. Structural integrity of rhGH is of critical importance for its clinical use and modifications thereof may act as markers in situations such as rhGH doping, as illegal rhGH-abuse in sports is of increasing interest. In the current study we investigated homogeneity of Norditropin, a recombinant human growth hormone frequently used in medicine, expressed in E. coli, strain MC1061. The most recent proteomics technologies including 2-DE, MALDI-MS followed by MALDI-MS/MS and LC-MS followed by LC-MS/MS were used for the characterisation of rhGH. MALDI-TOF-TOF and electrospray LC-MS analysis revealed one major protein with an average molecular mass of 22 126.0 Da and some additional minor components. Electrospray LC-MS/MS of the enzymatically digested Norditropin sample showed deamidation of N(12)N(149) and N(159), oxidation of M(14), M(125) and M(170) and one amino acid exchange V(14) for M(14) present in <1% of Norditropin. While deamidation and oxidation may be due to technical reasons, the single amino acid exchange may reflect infidelity of translation rather than codon usage and copy editing by E. coli.
Compensation of internal thermal stresses in InGaAsP/InP lasers for polarization stabilization (1985)

Internal thermal stresses in the active layer of a conventional InGaAsP/InP laser may cause polarization instabilities which normally do not exist in conventional AlGaAs/GaAs lasers. We analyze a structure with a buffer layer for Polarization stabilization by compensation of the internal thermal stresses in InGaAsP/InP lasers. Stress analyses are carried out for various structures to obtain the conditions for optimal stress-free structures. The effects of stresses from external sources are also discussed.
Issues Associated with the Development of a Wide-Area Analysis and Visualization Environment (2006)

This paper provides a discussion of issues associated with the development of an environment for wide-area power system analysis and visualization. In particular, the paper considers issues associated with the exchange of information between regional transmission operators, the use of a unified state estimation and contingency analysis solution, and the visualization of the results.
Four distinct regulatory regions of the cut locus and their effect on cell type specification in Drosophila. (1991)

The cut gene in Drosophila is necessary in at least one cell type, the external sensory organs, for proper cell type specification and morphogenesis. It is also expressed in a variety of other tissues, where its function is less well characterized. Previous work has demonstrated that mutations affecting all the tissues map in the transcribed and translated portion of the gene, while mutations that are tissue specific in their effects map in the 140 kb upstream of the most 5' exon known. Within that 140 kb, the mutations fall into four subregions, two of which contain mutations affecting unique sets of tissues and the other two of which contain mutations that affect a third set. Our examination of the defects of mutants, their complementation behavior, and their effect on the distribution of the cut protein in embryos, alters the picture in three important ways. First, some mutations convert the cells of the Malpighian tubules into what appear to be gut cells, suggesting that cut is necessary for cell type specification and morphogenesis in a variety of tissues. Second, mutations in each of the four subregions in the 140 kb of upstream DNA cause a different set of phenotypes, suggesting that the regulatory region contains at least four separate units with different tissue specific functions. And third, mutations have now been identified that map in the transcribed and translated portion of the gene but that have tissue specific effects.

Probe position recovery for ptychographical imaging (2010)

Ptychographical iterative phase retrieval is a promising new transmission imaging technique which uses a set of measured intensities from the consecutive illumination of overlapping regions of the specimen to form an image of the transmission function in phase and amplitude. Although the technique has been shown to work very effectively in both the light-optical and X-ray domains, electron ptychography poses significant difficulties, not least of which is the uncertainty in probe position due to drift and other instabilities. We demonstrate three methods for deriving the relative positions of the illumination spot on the specimen a-posteriori.

A Study of the Internal Forces in a Variable-Displacement Vane-Pump—Part I: A Theoretical Analysis (1986)

Growing energy costs continue to motivate the use of variable-displacement pumps in hydraulic systems with varying flow requirements. This study presents an analysis of the internal pressure-distribution in variable-displacement vane-pumps, and of the resulting forces and torques applied to their mechanisms and shafts. This analysis is essential to the study of the pump dynamics and control, the pump design, and the selection of the pump bearings. These forces are shown to be a function of the line pressure, the pump eccentricity, the shaft rotational speed, the fluid bulk modulus, the fluid viscosity, and the design geometry. These forces are composed of two periodic components: a continuous component due to the exposure of chambers to the line port, and an intermittent component due to a hydraulic-lock phenomenon. A design criterion is formulated which eliminates magnitude variations in the continuous component of the radial shaft-load.

Stereoscopic dual-energy X-ray imaging for target materials identification (2003)

An experimental stereoscopic dual-energy X-ray imaging system is employed to extract the effective atomic number from a target layer of multiple layers of different materials. Further work investigated utilising stereoscopic parallax data to calculate layer thickness which, when combined with dual-energy data, enables the mass density of the target to be established. The research is part of an ongoing programme of work in collaboration with the UK Home Office to discriminate and identify substances in X-ray security screening applications. Initial work utilised a basis materials decomposition (BMD) technique to compute the characteristic angle, an indicator of atomic composition. The problem of overlapping materials masking a target was solved by further refinement of the BMD method, which can also be used determine mass density when layer thickness is known. The empirical investigation concentrated on computing the characteristic angle for different target materials in various overlapping arrangements. Also, the results from employing manually extracted parallax data to calculate the thickness of a target material are presented together with the resultant estimation of the targets' mass density.
The 10 largest public and philanthropic funders of health research in the world: what they fund and how they distribute their funds (2016)

There is a need for increased transparency about who the main funders of health research are globally, what they fund and how they decide on what gets funded, and for improving the evidence base for various funding models. Data on organizations' funding patterns and funding distribution mechanisms are often not available, and when they are, they are reported using different classification systems. To start increasing transparency in health research funding, we have established www.healthresearchfunders.org that lists health research funding organizations worldwide and their health research expenditures.
The Adoption and use of Collaboration Information Technologies: International Comparisons (2005)

Information technology (IT) applications to support group decision processes have been of considerable interest over the years. With the emergence of virtual team arrangements and the advent of emerging information and networking technologies, an increasing amount of attention is now being aimed at understanding collaboration among group members, as they make decisions to accomplish tasks. Effective and efficient collaboration is critical from a decision quality and decision timeliness standpoint. Commonly known as collaborative information technologies (CITs), many technology solutions have the capability to enhance collaboration and facilitate group decisions in task accomplishment by enabling better communication, sharing of information, ideas, expertise, and evaluating alternatives, irrespective of time and distance barriers. Many studies have investigated such individual CIT solutions in different regional settings. However, despite the fact that no single medium can support collaboration in different types of tasks, there is a scarcity of research investigating the adoption and use of multiple CIT options across regions. This paper builds upon innovation diffusion theory and tests a research model to validate five antecedents of collective adoption and use of seven CITs in the US, Australia, and Hong Kong. Sub-sample analyses of data collected from 344 organizations in these three regions suggest that not only do adoption and use patterns of some CIT solutions vary across regions but so do the antecedents that explain their proliferation. Implications of our findings are discussed for practitioners and researchers.
“MEDICAL OOPHORECTOMY” USING A LONG-ACTING GNRH AGONIST-A POSSIBLE NEW APPROACH TO THE TREATMENT OF ENDOMETRIOSIS. (1982)

Five women with endometriosis were given a daily dose of a potent long-acting GnRH agonist, D-Trp6-Pro9-Net-LHRH (GnRH-A) for 28 days in an attempt to suppress ovarian estrogen secretion. The mean level of estradiol (E2) during sampling over 24 hours decreased (P less than 0.01) from 62 +/- 11 to 10 +/- 1 pg/ml at the end of treatment. Mean concentrations of androstenedione, testosterone, estrone and E2 on day 28 of therapy were similar to those measured in oophorectomized women. The level of FSH was decreased (P less than 0.001) during GnRH-a, whereas that of LH was significantly (P less than 0.001) increased, suggesting differing intracellular control mechanisms for release of the two gonadotropins. Desensitization of the pituitary was demonstrated at the end of treatment by a complete lack of acute response of FSH or LH to the daily dose of GnRH-a. "Medical oophorectomy" provides a new approach to the treatment of endometriosis.

A view synthesis method based on object coding and simple disparity model (2005)

We propose a simple view synthesis method based on object coding and simple modeling of disparity space. In the proposed method, a scene from a binocular stereo-vision camera is divided into objects and planes. Our purpose is not a "physically correct" but a "subjectively acceptable" view synthesis within the video-rate, in order to provide convincing images, using MPEG4 object video coding. The proposed method uses interpolation/extrapolation to generate images from arbitrary viewpoints. It also conceals void areas behind objects by using surrounding texture information.
Why can't i find my files? new methods for automating attribute assignment (2003)

Attribute-based naming enables powerful search and organization tools for ever-increasing user data sets. However, such tools are only useful in combination with accurate attribute assignment. Existing systems rely on user input and content analysis, but they have enjoyed minimal success. This paper discusses new approaches to automatically assigning attributes to files, including several forms of context analysis, which has been highly successful in the Google web search engine. With extensions like application hints (e.g., web links for downloaded files) and inter-file relationships, it should be possible to infer useful attributes for many files, making attribute-based search tools more effective.
Single-molecule imaging of full protein synthesis by immobilized ribosomes (2008)

How folding of proteins is coupled to their synthesis remains poorly understood. Here, we apply single-molecule fluorescence imaging to full protein synthesis in vitro. Ribosomes were specifically immobilized onto glass surfaces and synthesis of green fluorescent protein (GFP) was achieved using modified commercial Protein Synthesis using Recombinant Elements that lacked ribosomes but contained purified factors and enzyme that are required for translation in Escherichia coli. Translation was monitored using a GFP mutant (F64L/S65T/F99S/M153T/V163A) that has a high fluorophore maturation rate and that contained the Secretion Monitor arrest sequence to prevent dissociation from the ribosome. Immobilized ribosomal subunits were labeled with Cy3 and GFP synthesis was measured by colocalization of GFP fluorescence with the ribosome position. The rate of appearance of colocalized ribosome GFP was equivalent to the rates of fluorescence appearance coupled with translation measured in bulk, and the ribosome-polypeptide complexes were stable for hours. The methods presented here are applicable to single-molecule investigation of translational initiation, elongation and cotranslational folding.

A new method for estimating the aperture uncertainty of A/D converters (1998)

Aperture uncertainty measurements are strongly influenced by quantization, converter nonlinearity and test setup noise. The proposed method solves the difficulties arising from quantization, and nonlinearity. The method estimates the noise distribution function by fine adjustment of the input signal offset. The contribution of jitter-induced voltage noise is separated from additive noise in two different ways. Finally, the aperture uncertainty, assumed independent of the frequency, is estimated by varying the signal frequency. Experimental results obtained on 8 and 10 bit converters are discussed.
Polycrystalline Zn<sub>3</sub>P<sub>2</sub>/Indium-Tin Oxide Solar Cells (1983)

Zinc phosphide (Zn 3 P 2 )/indium-tin oxide (ITO) heterojunction solar cells are fabricated by rf sputter depositing ITO on large grain polycrystalline Zn 3 P 2 wafers. An AES analysis indicates that sputter etching of the Zn 3 P 2 wafer surface before depositing ITO is of great importance in achieving a better performance as a solar cell. The passivation of Zn 3 P 2 by reaction with atomic hydrogen is found to improve the cell performance significantly. Consequently, a power conversion efficiency of 2.1% (6 mm 2 in active area) has been obtained without antireflection coating.
Highly selective terahertz optical frequency comb generator (1997)

Using a 10.5-GHz resonant electro-optic modulator placed inside a resonant optical cavity, we generated an optical frequency comb with a span wider than 3 THz. The optical resonator consists of three mirrors, with the output coupler being a thin Fabry-Perot cavity with a free spectral range of 2 THz and a finesse of 400. Tuning this filter cavity onto resonance with a particular high-order sideband permits efficient output coupling of the desired sideband power from the comb generator, while keeping all other sidebands inside for continued comb generation. This spectrally pure output light was then heterodyne detected by another laser with a frequency offset of the order of 1 THz.

Ozone Quenching Properties of Isoprene and Its Antioxidant Role in Leaves (2001)

Isoprene is formed in and emitted by plants and the reason for this apparent carbon waste is still unclear. It has been proposed that isoprene stabilizes cell and particularly chloroplast thylakoid membranes. We tested if membrane stabilization or isoprene reactivity with ozone induces protection against acute ozone exposures. The reduction of visible, physiological, anatomical, and ultrastructural (chloroplast) damage shows that clones of plants sensitive to ozone and unable to emit isoprene become resistant to acute and short exposure to ozone if they are fumigated with exogenous isoprene, and that isoprene-emitting plants that are sensitive to ozone do not suffer damage when exposed to ozone. Isoprene-induced ozone resistance is associated with the maintenance of photochemical efficiency and with a low energy dissipation, as indicated by fluorescence quenching. This suggests that isoprene effectively stabilizes thylakoid membranes. However, when isoprene reacts with ozone within the leaves or in a humid atmosphere, it quenches the ozone concentration to levels that are less or non-toxic for plants. Thus, protection from ozone in plants fumigated with isoprene may be due to a direct ozone quenching rather than to an induced resistance at membrane level. Irrespective of the mechanism, isoprene is one of the most effective antioxidants in plants.
