Online stereo camera calibration from scratch (2017)

Stereo cameras are among the most promising sensors for automated driving. For their deployment, however, calibration should be automated and possible in-situ. We propose a restructuring of bundle adjustment into an incremental online calibration system. It allows us to estimate all observable camera parameters on the fly. Both simulations and experiments with real world cameras show its capability to calibrate stereo rigs in real time while driving. With this method, cameras can be employed with almost no calibration overhead. Only the non-observable parameter of scale has to be defined in advance.
Diversity of zebrafish peripheral oscillators revealed by luciferase reporting (2006)

In various multicellular organisms, circadian clocks are present not only in the central nervous system, but also in peripheral organs and tissues. In mammals peripheral oscillators are not directly responsive to light, but are entrained by the central oscillator in the suprachiasmatic nucleus. These individual oscillators are diverse in their free-running periods and phases. In contrast, cultured peripheral tissues and cell lines from zebrafish are not only rhythmic, but can also be directly entrained by light. Because of the convenience of studying rhythms in cultured cells, however, little has been known about properties of individual oscillators in intact zebrafish. Here, we show the remarkable diversity and consistency of oscillator properties in various peripheral organs and tissues from the period3-luciferase (per3-luc) transgenic zebrafish. Tissue-dependent differences were found in free-running period, phase, response to light, and temperature compensation. Furthermore, cycling amplitudes were reduced at lower temperatures in some, but not all, of the organs tested. Finally, we found that per3-luc rhythms can free run in both constant dark and constant light with remarkably similar amplitudes, phases, and periods, despite the fact that the mRNA of per2 and per1 has been shown not to oscillate in constant light.

Inflammasome-Mediated Inhibition of Listeria monocytogenes-Stimulated Immunity Is Independent of Myelomonocytic Function (2013)

Activation of the Nlrc4 inflammasome results in the secretion of IL-1β and IL-18 through caspase-1 and induction of pyroptosis. L. monocytogenes engineered to activate Nlrc4 by expression of Legionella pneumophilia flagellin (L. monocytogenes L.p.FlaA) are less immunogenic for CD8(+) T cell responses than wt L. monocytogenes. It is also known that IL-1β orchestrates recruitment of myelomonocytic cells (MMC), which have been shown to interfere with T cell-dendritic cells (DC) interactions in splenic white pulp (WP), limiting T cell priming and protective immunity. We have further analyzed the role of MMCs in the immunogenicity of L. monocytogenes L.p.FlaA. We confirmed that MMCs infiltrate the WP between 24-48 hours in response to wt L. monocytogenes infection and that depletion of MMCs enhances CD8(+) T cell priming and protective memory. L. monocytogenes L.p.FlaA elicited accelerated recruitment of MMCs into the WP. While MMCs contribute to control of L. monocytogenes L.p.FlaA, MMC depletion did not increase immunogenicity of L.p.FlaA expressing strains. There was a significant decrease in L. monocytogenes L.p.FlaA in CD8α(+) DCs independent of MMCs. These findings suggest that limiting inflammasome activation is important for bacterial accumulation in CD8α(+) DCs, which are known to be critical for T cell response to L. monocytogenes.
Structure of the SW Iberian Margin from Combined Wide-angle and Multichannel Seismic Reflection Data (FRAME Project) (2020)

&amp;lt;p&amp;gt;The SW Iberian Margin has a complex tectonic setting and crustal structure derived from a succession of rift events related to the opening of North Atlantic and Neotethys, from the Mesozoic to the Lower Cretaceous, and subsequent compression between Africa and Eurasia from the Lower Oligocene to present. This setting led to the reactivation of pre-existing strike-slip and extensional faults enhancing the seismogenic and tsunamigenic potential of the area. Thus, understanding of lithospheric structure along the SW Iberian Margin is not only important to study the rifting evolution but also to characterize the distribution of major lithospheric-scale boundaries, currently active and potentially capable of generating great seismic events of similar magnitude to the catastrophic 1755 Lisbon tsunamigenic earthquake, with estimated M&amp;lt;sub&amp;gt;W&amp;lt;/sub&amp;gt;&amp;gt;8.5.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;To this end, we use spatially coincident wide-angle seismic (WAS) and multichannel seismic (MCS) data collected along a ~320 km-long, NW-SE trending transect across the SW Iberian margin, during the FRAME survey in 2018. WAS data were recorded with by 24 ocean bottom seismometers and hydrophones (OBS/H), deployed each ~10km, while MCS data was recorded with a 6 km-long streamer. From NW to SE, the transect runs from the Tagus Abyssal plain to the westernmost extension of the Gulf of Cadiz area, across three major thrust faults: the Marqu&amp;amp;#234;s de Pombal fault, S&amp;amp;#227;o Vicente fault, and Horseshoe fault.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;We applied joint refraction and reflection travel-time tomography using a combination of WAS refractions and reflections and MCS reflections to invert for the 2D P-wave velocity structure of the crust and uppermost mantle, and the geometry of the main seismic interfaces, namely the top of the acoustic basement and the Moho. The combination of WAS and MCS reflection travel-times brings a significant increase in the resolution of the tomographic model, and especially in the definition of the geometry of the inverted reflectors (i.e. top of the basement), because MCS data has a higher spatial sampling than WAS data in these shallow regions.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;In the preliminary model, the Moho shallows beneath the north-eastward continuation of the Horseshoe Basin and the Gorringe Bank, coinciding with the location of the three major thrust faults mentioned before, and defining three major crustal blocks along the model. Further analysis of deep seismic phases from WAS records should provide additional information on the geometry and extent of these three major thrust faults.&amp;lt;/p&amp;gt;
EFFECT OF DISTRIBUTED GENERATION ON PROTECTION OF MEDIUM VOLTAGE CABLE GRIDS (2007)

Due to several reasons Distributed Generation, DG, is increasing. Most of the DG units are small in size and connected to medium voltage grids (MV-grids). DG units change the operation of MV-grids on several aspects such as voltage control, fault current level and protection. This paper focuses on the effect of small CHP units on the protection of MV-cable grids. After a brief introduction of the influence of DG on the protection of MV-grids, the effects will be illustrated by simulation. A comparison is made between a MV-grid containing only cables and a MVgrid containing overhead lines.
An UpperBound for The Capacity of Distributed MIMO Mobile Ad Hoc Networks (2006)

We compute an upper bound for the capacity of mobile wireless ad hoc networks (MANETs) when all the nodes in the network are endowed with multiple antennas.The derivation is based on a new communication scheme for wireless ad hoc networks utilizing the concept of cooperative many-to-many communication, which we show outperforms the conventional one-to-one communication approach.We assume that nodes transmit with low power, such that the total interference from other cells is much smaller than noise.Consequently, the results for the upper bound capacity is only valid for the low interference power regime.

Dual-Function Metal–Organic Framework as a Versatile Catalyst for Detoxifying Chemical Warfare Agent Simulants (2015)

The nanocrystals of a porphyrin-based zirconium(IV) metal-organic framework (MOF) are used as a dual-function catalyst for the simultaneous detoxification of two chemical warfare agent simulants at room temperature. Simulants of nerve agent (such as GD, VX) and mustard gas, dimethyl 4-nitrophenyl phosphate and 2-chloroethyl ethyl sulfide, have been hydrolyzed and oxidized, respectively, to nontoxic products via a pair of pathways catalyzed by the same MOF. Phosphotriesterase-like activity of the Zr6-containing node combined with photoactivity of the porphyrin linker gives rise to a versatile MOF catalyst. In addition, bringing the MOF crystals down to the nanoregime leads to acceleration of the catalysis.
Through-space communication in a TTF–C60–TTF triad (2007)

A 2-pyrazolino[60]fullerene-based triad, possessing two TTF units connected with flexible long linkages, has been prepared. Fluorescence quenching was observed in polar and non-polar solvents, suggesting the existence of a through-space photoinduced charge separation process with rates faster than 3.8 × 109 s−1 and with high efficiency (>0.85). The charge separated states were confirmed by transient absorption spectra in the visible and near-IR regions. The longest lifetime of the charge separated state was found to be 230 ns in CH2Cl2 solvent.
A 256/spl times/256 pixel smart CMOS image sensor for line-based stereo vision applications (2000)

This paper presents a 256/spl times/256 pixel smart CMOS image sensor for line based vision applications. By combining the edge-based analog processing technique with an active pixel array, a dense and fast on-chip analog image processing has been achieved. The on-chip processing unit includes (1) an analog histogram equalizer, (2) a programmable recursive Gaussian filter, (3) a spatio-temporal differentiator, and (4) a local extrema extractor. An electronic shutter is applied to the active pixel sensor array in order to adapt the exposure time as a function of global illumination. The on-chip histogram equalizer extends the image into a constant and optimal range for all the following processing operators and gives a stable and predictable precision of the analog processing. A prototype chip has been designed and fabricated in a standard 0.8-/spl mu/m CMOS process with double poly and double metal, giving a pixel pitch of 20 /spl mu/m and die size of 7/spl times/7 mm/sup 2/. A line processing time is compatible with TV line scan period. The worst case power consumption measures 40 mA at 5 V.
Halo doping effects in submicron DI-LDD device design (1985)

The design of DI-LDD submicron channel devices is investigated, specifically focusing on the halo optimization for punchthrough and threshold falloff protection. Two dimensional numerical analysis is used to demonstrate the tradeoff between breakdown voltage and improved short channel threshold falloff as the halo concentration is increased. For a given halo doping level, there is a maximum permitted drain voltage for each channel length which is limited by avalanche breakdown, drain induced threshold lowering and punch-through. A window of useful halo doses is established from <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5\times10^{16}</tex> to about <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">8\times10^{17}</tex> below which there is no significant improvement of the device and above which there is an unacceptable level of device degradation. A maximum V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ds</inf> versus channel length curve for the polysilicon gate DI-LDD MOSFET is obtained which implies that power supply voltage must be scaled by approximately the same factor as channel length for this type of device.
Impact of a Long-Term High Fat Diet on Bone Microarchitecture and Muscle Structure in Adult Male and Female Normal Mice (2019)

Background and Hypothesis: Hyperglycemia is a major source of disease and morbidity among the adult population. Prior studies correlate long-term high fat diet (HFD) mediated hyperglycemia with bone fragility and muscle weakness. Furthermore, the mechanism driving hyperglycemia between sexes are unknown. Our group previously showed that HFDs induced insulin resistance in male mice and glucose intolerance in female mice. This establishes the need to study the impact of long-term HFDs on the bones and muscles using an older cohort of both male and female mice. For that, we hypothesized a long-term HFD mediated hyperglycemia will change bone and muscle structures and impair their functions in adult male and female mice. Experimental Design or Project Methods: 22-week C57Bl6 mice were fed either a HFD or low fat diet (LFD) for 25 weeks. After euthanasia, bones and muscles were harvested and evaluated using MicroCT, histology, and mechanical testing. Statistical analysis was performed using GraphPad Prism with p&lt;0.05 considered significant. Results: MicoCT data saw significant reductions to cortical thickness (p&lt;0.05), bone mineral density (p&lt;0.001), and increases to medullary area (p&lt;0.05) among HFD males and females compared to LFD. HFD-males also experienced significant increase in cortical porosity (P&lt;0.001) whereas no changes were noted in HFDfemales. Trabecular bone volume was relatively unchanged. HFD increased cortical osteoclast surface (p&lt;0.001) for both sexes. Bone histology saw increased marrow adiposity among HFD-females (p&lt;0.05). Muscle histology exhibited HFD-related reductions in myofiber diameter (p&lt;0.001) for both sexes. Mechanical testing demonstrated reduced young’s modulus (p&lt;0.05) and yield stress (p&lt;0.05) among HFD mice, despite non-significant differences in ultimate strength. Conclusion and Potential Impact: The changes associated with a long-term HFD differed between sexes but still led to functional impairments of bone and muscle for both sexes, emphasizing the importance of looking further into the mechanisms responsible for these changes. This can potentially translate to the clinic in the treatment of musculoskeletal complications associated with HFDs.
Seeded laser-induced cavitation for studying high-strain-rate irreversible deformation of soft materials (2020)

Characterizing the high-strain-rate and high-strain mechanics of soft materials is critical to understanding the complex behavior of polymers and various dynamic injury mechanisms, including traumatic brain injury. However, their dynamic mechanical deformation under extreme conditions is technically difficult to quantify and often includes irreversible damage. To address such challenges, we investigate an experimental method, which allows quantification of the extreme mechanical properties of soft materials using ultrafast stroboscopic imaging of highly reproducible laser-induced cavitation events. As a reference material, we characterize variably cross-linked polydimethylsiloxane specimens using this method. The consistency of the laser-induced cavitation is achieved through the introduction of laser absorbing seed microspheres. Based on a simplified viscoelastic model, representative high-strain-rate shear moduli and viscosities of the soft specimens are quantified across different degrees of crosslinking. The quantified rheological parameters align well with the time-temperature superposition prediction of dynamic mechanical analysis. The presented method offers significant advantages with regard to quantifying high-strain rate, irreversible mechanical properties of soft materials and tissues, compared to other methods that rely upon the cyclic dynamics of cavitation. These advances are anticipated to aid in the understanding of how damage and injury develop in soft materials and tissues.

[Study of Y-chromatin in the buccal epithelium of man]. (1975)

Investigation was carried on by fluorescent-microscopic technique, smears of buccal epithelium being stained with acrichinium-mustard gas. The extent, form, location in a nucleus and the frequency of Y-chromatin in human buccal smears were studied. In medico-genetic practice this method is employed for initial determination of chromosome sex in disease associated with anomalies of sex chromosomes.
$A^2$-Nets: Double Attention Networks (2018)

Learning to capture long-range relations is fundamental to image/video recognition. Existing CNN models generally rely on increasing depth to model such relations which is highly inefficient. In this work, we propose the "double attention block", a novel component that aggregates and propagates informative global features from the entire spatio-temporal space of input images/videos, enabling subsequent convolution layers to access features from the entire space efficiently. The component is designed with a double attention mechanism in two steps, where the first step gathers features from the entire space into a compact set through second-order attention pooling and the second step adaptively selects and distributes features to each location via another attention. The proposed double attention block is easy to adopt and can be plugged into existing deep neural networks conveniently. We conduct extensive ablation studies and experiments on both image and video recognition tasks for evaluating its performance. On the image recognition task, a ResNet-50 equipped with our double attention blocks outperforms a much larger ResNet-152 architecture on ImageNet-1k dataset with over 40% less the number of parameters and less FLOPs. On the action recognition task, our proposed model achieves the state-of-the-art results on the Kinetics and UCF-101 datasets with significantly higher efficiency than recent works.
A Novel Methodology for Optimal Design of Compressor Plants Using Probabilistic Plant Design (2013)

Equipment sizing decisions in the oil and gas industry often have to be made based on incomplete data. Often, the exact process conditions are based on numerous assumptions about well performance, market conditions, environmental conditions, and others. Since the ultimate goal is to meet production commitments, the traditional method of addressing this is to use worst case conditions and often adding margins onto these. This will invariably lead to plants that are oversized, in some instances, by large margins. In reality, the operating conditions are very rarely the assumed worst case conditions, however, they are usually more benign most of the time. Plants designed based on worst case conditions, once in operation, will, therefore, usually not operate under optimum conditions, have reduced flexibility, and therefore cause both higher capital and operating expenses. The authors outline a new probabilistic methodology that provides a framework for more intelligent process-machine designs. A standardized framework using a Monte Carlo simulation and risk analysis is presented that more accurately defines process uncertainty and its impact on machine performance. Case studies are presented that highlight the methodology as applied to critical turbomachinery.

Nucleases in the autolysis of filamentous fungi (1990)

RNase and DNase activities were studied in seven fungi of the subdivisions Ascomycotina, Zygomycotina and Basidiomycotina during their autolysis, and extracellular and intracellular RNase and DNase were found. RNase specific activity reached higher levels than DNase specific activity in the culture liquid and mycelial extract, except in Aspergillus nidulans. Generally maximal RNase specific activities were observed at the onset of autolysis in the culture liquid. In the mycelial extract an increase in this activity with the incubation time was observed, except in A. nidulans and Coriolus versicolor. The highest values of DNase specific activities were found at the third day of autolysis in A. nidulans culture liquid and at the thirtieth day of autolysis in Schizophyllum commune mycelial extract. A possible relationship between the culture liquid pH during the autolysis of the studied fungi and the levels of DNase specific activity was observed.
Using near‐field coupled circularly polarised antennas as frequency‐independent variable phase shifters (2014)

A novel concept of frequency‐independent variable phase shifters is introduced. It is based on the use of circularly polarised (CP) antennas coupled in the near‐field. For transmission between two CP antennas in the far‐field, a rotation around the boresight axis produces a phase change in the transfer function. This concept is exploited and validated also for near‐field coupling between two CP antennas. Therefore, two close‐coupled CP antennas can act as an adjustable phase shifter with the phase shift controlled by the angle between the structures. The bandwidth depends on the CP bandwidth of the antenna. This concept is valuable for future phase shifters in millimetre‐wave applications where rotation can be facilitated by MEMS elements.
