Clinical approach to paroxysmal atrial fibrillation (1990)

In addition to the role of the electrophysiological substrate, paroxysmal atrial fibrillation depends on the modulation of the atrial tissues by the autonomic nervous system. Experimentally, models of atrial fibrillation can be based on either adrenergic or vagal stimulations that provoke the arrhythmia by disturbing in a different way conduction and refractory periods of the atrium. Clinically, the role of the autonomic nervous system can be suspected from the clinical history, and paroxysmal attacks can typically be observed either at daytime or at night, at exercise or at rest. Careful attention should be paid to the changes of heart rate that occur in the minutes or tens of minutes prior to the attacks, and the trend of acceleration or slowing of cardiac frequency observed in Holter tracings provides reliable indications of the state of the vago-sympathetic balance in these patients. During the attacks, the electrocardiographic aspect of atrial flutter alternating with a pattern of atrial fibrillation is typical of vagally dependent arrhythmias, whereas atrial tachycardia is more frequently observed at the onset of adrenergic atrial fibrillation. When the paroxysmal forms of arrhythmia are resistant to usual pure antiarrhythmic therapy including type IA agents and flecainide or encainide, one should take into account the role of the autonomic nervous system. Propafenone, or beta-blockers combined with type I drugs, are very effective every time an adrenergic factor is involved, but prevent the beneficial role of other agents if a vagal mechanism is predominant.(ABSTRACT TRUNCATED AT 250 WORDS)

Micro Drilling using 2-directional Vibration in a Plane (2010)

By generating 2-directional vibration in a xy plane of workpiece table, a newly developed micro drilling using 2-directional vibration was carried out. The vibration was produced by applying sinusoidal voltages to the orthogonally arranged piezoelectric materials built in the workpiece excitation table. Through the micro-drilling experiments using poly-carbonate and brass material, it was found that micro drilling using 2-directional vibration in a workpiece table could be an efficient method to enhance the form accuracy of machined workpiece by suppressing burr formation at both entry and exit region. A higher form accuracy could be obtained by increasing stiffness of feeding mechanism, decrease of geometric tolerance of combining jig, and development of high performance excitation table which generates amplified vibration at higher frequency.
Active unsupervised texture segmentation on a diffusion based feature space (2003)

We propose a novel and efficient approach for active unsupervised texture segmentation. First, we show how we can extract a small set of good features for texture segmentation based on the structure tensor and nonlinear diffusion. Then, we propose a variational framework that incorporates these features in a level set based unsupervised segmentation process that adaptively takes into account their estimated statistical information inside and outside the region to segment. The approach has been tested on various textured images, and its performance is favorably compared to recent studies.
The X-ray Crystal Structure of the NF-κB p50·p65 Heterodimer Bound to the Interferon β-κB Site (2002)

We have determined the x-ray crystal structure of the transcription factor NF-kappaB p50.p65 heterodimer complexed to kappaB DNA from the cytokine interferon beta enhancer (IFNbeta-kappaB). To better understand how the binding modes of NF-kappaB on its two best studied DNA targets might contribute to promoter-specific transcription, this structure is compared with the previously determined complex crystal structure containing NF-kappaB bound to the Ig kappa light chain gene enhancer as well as to a second NF-kappaB.Ig kappa light chain gene enhancer complex also reported in this paper. The global binding modes of all NF-kappaB.DNA complex structures are similar, although crystal-packing interactions lead to differences between identical complexes of the same crystallographic asymmetric unit. An extensive network of stacked amino acid side chains that contribute to base-specific DNA contacts is conserved among the three complexes. Consistent with earlier reports, however, the IFNbeta-kappaB DNA is bent significantly less by NF-kappaB than is the Ig kappa light chain gene enhancer. This and other small structural changes may play a role in explaining why NF-kappaB-directed transcription is sensitive to the context of specific promoters. The precise molecular mechanism behind the involvement of the high mobility group protein I(Y) in interferon beta enhanceosome formation remains elusive.
Biologically inspired neural networks for spatio-temporal planning in robotic navigation tasks (2011)

In this paper we present a biologically-inspired model of spatio-temporal learning in the hippocampus and prefrontal cortex which can be used in tasks requiring the behavior of the robot to be constrained by sensory and temporal information. In this model chains of sensory events are learned and associated with motor actions. The temporality of these sequences is also learned and can be used to predict the timing of upcoming events. The neural network acts as a novelty detector and can modulate the behavior of the robot in case its actions do not have the expected consequences. The system is used to solve two different robotic navigation tasks involving an alternation between random exploration, goal-directed navigation and waiting periods of various lengths.
Dynamic dependence of interaction potentials for keV atoms at metal surfaces (2004)

He and N atoms are scattered with keV energies under a grazing angle of incidence from clean and flat Ag(111) and Al(111) surfaces. For incidence along low index crystallographic directions in the surface plane, atomic projectiles are steered by rows of atoms (``axial surface channeling'') giving rise to characteristic rainbows in their angular distribution. From the analysis of this effect we derive effective scattering potentials which reveal pronounced dynamical effects. We attribute our observation to the embedding energy for penetration of atoms in the electron gas of a metal.
<b>Specific binding of the<i> Listeria monocytogenes</i> transcriptional regulator PrfA to target sequences requires additional factor(s) and is influenced by iron</b> (1996)

The PrfA protein, which is a member of the Crp/Fnr family of prokaryotic transcription activators, regulates the virulence genes of Listeria monocytogenes. In this work, specific binding of PrfA to its target DNA was determined by electrophoretic mobility-shift assays (EMSAs) using cell-free extracts from the two L. monocytogenes strains EGD and NCTC 7973. PrfA-specific binding differs between the two strains, even when the concentration of PrfA was adjusted to similar levels. Both strains exhibited increased PrfA-specific binding after a shift into minimal essential medium (MEM) without showing a significant change in the amount of PrfA protein, relative to extracts from bacteria grown in brain-heart infusion (BHI). The purified PrfA protein from strain EGD produced in Escherichia coli did not exhibit specific binding to the target DNA but did so upon addition of PrfA-free extracts from various Listeria species and Bacillus subtilis. The observed activation of PrfA seems to be caused by a PrfA-activating factor (Paf), which is probably a protein since elevated temperature, but not RNase treatment, destroyed the activation potential of such PrfA-free extracts. Moreover, fractionation of these extracts by sucrose gradient centrifugation yielded the Paf activity in a fraction sedimenting at 3.2 S. Specific binding of PrfA-containing extracts from strain EGD to the hly and actA promoter sequences was strongly inhibited by iron, whereas that of extracts from strain NCTC 7973 was only slightly reduced. The iron effect seems to be mediated by Paf rather than by PrfA itself.
Rapid Detection of Tembusu Virus by Reverse-Transcription, Loop-mediated Isothermal Amplification (RT-LAMP) (2011)

A sensitive reverse-transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the rapid detection of Tembusu virus (TMUV) infection. The reaction was performed in one step in a single tube at 64°C for 45 min, with SYBR Green I dye added prior to amplification. The detection limit of the RT-LAMP assay was approximately 10 copies/μl, and no cross-reaction with other avian viruses was observed. The assay was evaluated further for the diagnosis of TMUV in field samples and compared with conventional RT-PCR, demonstrating that results of the RT-LAMP assay corresponded to those of conventional RT-PCR. In conclusion, RT-LAMP with SYBR Green I dye was shown to be a sensitive, simple assay for the rapid diagnosis of TMUV infection in ducks.
High speed and high power polarization insensitive germanium photodetector with lumped structure (2016)

We propose and demonstrate a high speed and high power polarization insensitive germanium photodetector (Ge PD) with lumped structure based on related parallel Ge absorption regions. Two absorption regions are double sides illuminated to optimize the space charge density and the two dimensional (2D) grating coupler is adopted for both coupling and polarization independent operation. Being different from previous reported high power scheme with separate absorption areas, the proposed structure is specifically designed with doubled but related Ge absorption regions, forming the equivalent parallel resistor and thus the parasitic parameter can be engineered to ensure a simultaneous large bandwidth. The bandwidth is measured to be >35 GHz, while the maximum current density is measured to be 1.152 mA/μm<sup>3</sup>. The dark current and the responsivity of the proposed Ge PD are measured to be 1.82 μΑ and 1.06 A/W. Modulated signals experimentally validate the high speed operation and doubled power handling capacity for the proposed scheme. Furthermore, the bit error rate results show the superior performance for the proposed Ge PD at high photocurrent.
Fiber-optic Fabry-Perot strain rosettes (1992)

The concept of a fiber-optic strain rosette is introduced. A mathematical framework describing how surface adhered optical fibers can be configured to measure the state of strain is presented. Details of the design, fabrication, and testing of fiber-optic strain rosettes based on Fabry-Perot interferometers are given. The performance of these devices indicates that they are viable alternatives to resistive-foil rosettes in situations where the benefits of using optical fiber for strain measurement are significant.
Sensor Analysis for Fault Detection in Tightly-Coupled Multi-Robot Team Tasks (2007)

This paper presents a sensor analysis based fault detection approach (which we call SAFDetection) that is used to monitor tightly-coupled multi-robot team tasks. Our approach aims at detecting both physical and logic faults of a robot system with little prior knowledge on the system. We do not need the motion model or a priori knowledge of the possible fault types of the monitored system. Our approach treats the monitored robot system as a black box, with only sensor data available. Thus, we believe the approach is general, and can be used in a wide variety of robot systems performing many different kinds of tasks. Our approach combines data clustering techniques with the generation of a probabilistic state diagram to model the normal operation of the multi-robot system. We have implemented this approach on a physical robot team. This paper presents the results of these experiments, which show that sensor data analyzed from a training phase of normal operation can be used to generate a model of normal robot team operation. This model can then be used to detect many types of abnormal behavior of the system, based purely on monitoring the sensor data of the system.
Induction of a retinoblastoma phosphatase activity by anticancer drugs accompanies p53-independent G1 arrest and apoptosis. (1995)

DNA-damaging agents induce accumulation of the tumor suppressor and G1 checkpoint protein p53, leading cells to either growth arrest in G1 or apoptosis (programmed cell death). The p53-dependent G1 arrest involves induction of p21 (also called WAF1/CIP1/SDI1), which prevents cyclin kinase-mediated phosphorylation of retinoblastoma protein (RB). Recent studies suggest a p53-independent G1 checkpoint as well; however, little is known about its molecular mechanisms. We report that induction of a protein-serine/threonine phosphatase activity by DNA damage signals is at least one of the mechanisms responsible for p53-independent, RB-mediated G1 arrest and consequent apoptosis. When two p53-null human leukemic cell lines (HL-60 and U-937) were treated with a variety of anticancer agents, RB became hypophosphorylated, accompanied with G1 arrest. This was followed immediately (in less than 30 min) by apoptosis, as determined by the accumulation of pre-G1 apoptotic cells and the internucleosomal fragmentation of DNA. Addition of calyculin A or okadaic acid (specific serine/threonine phosphatase inhibitors) or zinc chloride (apoptosis inhibitor) prevented the G1 arrest- and apoptosis-specific RB dephosphorylation. The levels of cyclin E- and cyclin A-associated kinase activities remained high during RB dephosphorylation, supporting the involvement of a chemotherapy-induced serine/threonine phosphatase(s) rather than p21. Furthermore, the induced phosphatase activity coimmunoprecipitated with the hyperphosphorylated RB and was active in a cell-free system that reproduced the growth arrest- and apoptosis-specific RB dephosphorylation, which was inhibitable by calyculin A but not zinc. We propose that the RB phosphatase(s) might be one of the p53-independent G1 checkpoint regulators.
Changing Perspective in Stereoscopic Images (2013)

Traditional image editing techniques cannot be directly used to edit stereoscopic ("3D") media, as extra constraints are needed to ensure consistent changes are made to both left and right images. Here, we consider manipulating perspective in stereoscopic pairs. A straightforward approach based on depth recovery is unsatisfactory: Instead, we use feature correspondences between stereoscopic image pairs. Given a new, user-specified perspective, we determine correspondence constraints under this perspective and optimize a 2D warp for each image that preserves straight lines and guarantees proper stereopsis relative to the new camera. Experiments verify that our method generates new stereoscopic views that correspond well to expected projections, for a wide range of specified perspective. Various advanced camera effects, such as dolly zoom and wide angle effects, can also be readily generated for stereoscopic image pairs using our method.
Robust High-Resolution Video Matting with Temporal Guidance (2022)

We introduce a robust, real-time, high-resolution human video matting method that achieves new state-of-the-art performance. Our method is much lighter than previous approaches and can process 4K at 76 FPS and HD at 104 FPS on an Nvidia GTX 1080Ti GPU. Unlike most existing methods that perform video matting frame-by-frame as independent images, our method uses a recurrent architecture to exploit temporal information in videos and achieves significant improvements in temporal coherence and matting quality. Furthermore, we propose a novel training strategy that enforces our network on both matting and segmentation objectives. This significantly improves our model’s robustness. Our method does not require any auxiliary inputs such as a trimap or a pre-captured background image, so it can be widely applied to existing human matting applications. Our code is available at https://peterl1n.github.io/RobustVideoMatting/
SDN Architecture and Southbound APIs for IPv6 Segment Routing Enabled Wide Area Networks (2018)

The SRv6 architecture (segment routing based on IPv6 data plane) is a promising solution to support services like Traffic Engineering, service function chaining and virtual private networks in IPv6 backbones and datacenters. The SRv6 architecture has interesting scalability properties as it reduces the amount of state information that needs to be configured in the nodes to support the network services. In this paper, we describe the advantages of complementing the SRv6 technology with an software defined networking (SDN) based approach in backbone networks. We discuss the architecture of a SRv6 enabled network based on Linux nodes. In addition, we present the design and implementation of the Southbound API between the SDN controller and the SRv6 device. We have defined a data-model and four different implementations of the API, respectively based on gRPC, REST, NETCONF, and remote command line interface. Since it is important to support both the development and testing aspects we have realized an Intent-based emulation system to build realistic and reproducible experiments. This collection of tools automate most of the configuration aspects relieving the experimenter from a significant effort. Finally, we have realized an evaluation of some performance aspects of our architecture and of the different variants of the Southbound APIs and we have analyzed the effects of the configuration updates in the SRv6 enabled nodes.

Higher-Order SVD-Based Subspace Estimation to Improve the Parameter Estimation Accuracy in Multidimensional Harmonic Retrieval Problems (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Multidimensional harmonic retrieval problems are encountered in a variety of signal processing applications including radar, sonar, communications, medical imaging, and the estimation of the parameters of the dominant multipath components from MIMO channel measurements. <formula formulatype="inline"> <tex>$R$</tex></formula>-dimensional subspace-based methods, such as <formula formulatype="inline"><tex>$R$</tex></formula>-D Unitary ESPRIT, <formula formulatype="inline"> <tex>$R$</tex></formula>-D RARE, or <formula formulatype="inline"><tex>$R$</tex> </formula>-D MUSIC, are frequently used for this task. Since the measurement data is multidimensional, current approaches require stacking the dimensions into one highly structured matrix. However, in the conventional subspace estimation step, e.g., via an SVD of the latter matrix, this structure is not exploited. In this paper, we define a measurement tensor and estimate the signal subspace through a higher-order SVD. This allows us to exploit the structure inherent in the measurement data already in the first step of the algorithm which leads to better estimates of the signal subspace. We show how the concepts of forward-backward averaging and the mapping of centro-Hermitian matrices to real-valued matrices of the same size can be extended to tensors. As examples, we develop the <formula formulatype="inline"><tex>$R$</tex></formula>-D standard Tensor-ESPRIT and the <formula formulatype="inline"><tex>$R$</tex></formula>-D Unitary Tensor-ESPRIT algorithms. However, these new concepts can be applied to any multidimensional subspace-based parameter estimation scheme. Significant improvements of the resulting parameter estimation accuracy are achieved if there is at least one of the <formula formulatype="inline"><tex>$R$</tex></formula> dimensions, which possesses a number of sensors that is larger than the number of sources. This can already be observed in the two-dimensional case. </para>
Stabilization of the Skeletal Muscle Ryanodine Receptor Ion Channel-FKBP12 Complex by the 1,4-Benzothiazepine Derivative S107 (2020)

Activation of the skeletal muscle ryanodine receptor (RyR1) complex results in the rapid release of Ca2+ from the sarcoplasmic reticulum and muscle contraction. Dissociation of the small FK506 binding protein 12 subunit (FKBP12) increases RyR1 activity and impairs muscle function. The 1,4-benzothiazepine derivative JTV519, and the more specific derivative S107 (2,3,4,5,-tetrahydro-7-methoxy-4-methyl-1,4-benzothiazepine), are thought to improve skeletal muscle function by stabilizing the RyR1-FKBP12 complex. Here, we report a high degree of nonspecific and specific low affinity [3H]S107 binding to SR vesicles. SR vesicles enriched in RyR1 bound ∼48 [3H]S107 per RyR1 tetramer with EC50 ∼52 µM and Hillslope ∼2. The effects of S107 and FKBP12 on RyR1 were examined under conditions that altered the redox state of RyR1. S107 increased FKBP12 binding to RyR1 in SR vesicles in the presence of reduced glutathione and the NO-donor NOC12, with no effect in the presence of oxidized glutathione. Addition of 0.15 µM FKBP12 to SR vesicles prevented FKBP12 dissociation; however, in the presence of oxidized glutathione and NOC12, FKBP12 dissociation was observed in skeletal muscle homogenates that contained 0.43 µM myoplasmic FKBP12 and was attenuated by S107. In single channel measurements with FKBP12-depleted RyR1s, in the absence and presence of NOC12, S107 augmented the FKBP12-mediated decrease in channel activity. The data suggest that S107 can reverse the harmful effects of redox active species on SR Ca2+ release in skeletal muscle by binding to RyR1 low affinity sites.
