SLAM via Variable Reduction from Constraint Maps (2006)

The two dominant forms of SLAM are based on Extended Kalman Filtering and Consistent Pose Estimation. We show that these are particular subsets of a more general view of the SLAM problem, in which variables representing all robot poses and features are kept. The general technique of variable reduction is a unifying view of these methods that is mathematically sound, and which enables us to explore other interesting and computationally compelling forms for solving SLAM problems.

Elucidating local pollution and site representativeness at the Jungfraujoch, Switzerland through parallel aerosol measurements at an adjacent mountain ridge (2021)

Abstract Many long-term air pollution and climate monitoring stations face the issue of increasing anthropogenic activities in their vicinity. Furthermore, the spatial representativeness of the sites is often not entirely understood especially in mountainous terrain with complex topographic features. This study presents a 5-year comparison of parallel aerosol measurements (total particle number concentration and equivalent black carbon mass concentration) at the Jungfraujoch in the Swiss Alps (JFJ, 3580 m a.s.l.), and an adjacent mountain ridge, the Jungfrau East Ridge (JER, 3705 m a.s.l.), in 1000 m air-line distance to the main site. The parallel aerosol measurements reveal characteristic differences in the diurnal variations between the two sites under certain specific meteorological conditions. Our analysis estimates that on 20%–40% of the days local activities at the Jungfraujoch have a clear influence on the measured time series of the total aerosol number concentration and the equivalent black carbon mass concentration. This influence is mainly seen in form of strong isolated spikes rather than by an increase in the on-site background concentration. They can thus be flagged during the data quality assurance process and filtered from those measurement parameters available at high time resolution. Removing the spikes from the original time series results in daily mean values for the total aerosol number concentration and equivalent black carbon mass concentration that are 5%–10% lower compared to the original signals. During nighttime with hardly any local pollution sources that cause spikes this percentage decreases towards 0%. The signal baselines at the Jungfraujoch and Jungfrau East Ridge correlate well during more than 50% of the days.
Changing concepts of atherogenesis (2000)

This review discusses three stages in the life history of an atheroma: initiation, progression and complication. Recruitment of mononuclear leucocytes to the intima characterizes initiation of the atherosclerotic lesion. Specific adhesion molecules expressed on the surface of vascular endothelial cells mediate leucocyte adhesion: the selectins and members of the immunoglobulin superfamily such as vascular cell adhesion molecule-1 (VCAM-1). Once adherent, the leucocytes enter the artery wall directed by chemoattractant chemokines such as macrophage chemoattractant protein-1 (MCP-1). Modified lipoproteins contain oxidized phospholipids which can elicit expression of adhesion molecule and cytokines implicated in early atherogenesis. Progression of atheroma involves accumulation of smooth muscle cells which elaborate extracellular matrix macromolecules. These processes appear to result from an eventual net positive balance of growth stimulatory versus growth inhibitory stimuli, including proteins (cytokines and growth factors) and small molecules (e.g. prostanoids and nitric oxide). The clinically important complications of atheroma usually involve thrombosis. Arterial stenoses by themselves seldom cause acute unstable angina or acute myocardial infarction. Indeed, sizeable atheroma may remain silent for decades or produce only stable symptoms such as angina pectoris precipitated by increased demand. Recent research has furnished new insight into the molecular mechanisms that cause transition from the chronic to the acute phase of atherosclerosis. Thrombus formation usually occurs because of a physical disruption of atherosclerotic plaque. The majority of coronary thromboses result from a rupture of the plaque's protective fibrous cap, which permits contact between blood and the highly thrombogenic material located in the lesion's lipid core, e.g. tissue factor. Interstitial collagen accounts for most of the tensile strength of the plaque's fibrous cap. The amount of collagen in the lesion's fibrous cap depends upon its rate of biosynthesis stimulated by factors released from platelets (e.g. transforming growth factor beta or platelet-derived growth factor), but inhibited by gamma interferon, a product of activated T cells found in plaques. Degradation by specialized enzymes (matrix metalloproteinases) also influences the level of collagen in the plaque's fibrous cap. Such studies illustrate how the application of cellular and molecular approaches has fostered a deeper understanding of the pathogenesis of atherosclerosis. This increased knowledge of the basic mechanisms enables us to understand how current therapies for atherosclerosis may act. Moreover, the insights derived from recent scientific advances should aid the discovery of new therapeutic targets that would stimulate development of novel treatments. Such new treatments could further reduce the considerable burden of morbidity and mortality due to this modern scourge, and reduce reliance on costly technologies that address the symptoms rather than the cause of atherosclerosis.

Association of plant injury with an air contaminant in a controlled environment facility (1974)

Gaseous compounds are common, yet seldom recognized contaminants in controlled environments. Injury to several plant species has been observed in the Biotron which uses trichloroethylene as a coolant in its centrally controlled system. Sometimes this compound is present in the rooms at an average level of 2 ppm, as measured by gas chromatography. Injury symptoms, which vary between species, are characteristic of air pollution injury. Present studies with Tagetes patula show a distinctive necrosis on the upper leaf surfaces. Experiments are being conducted to determine whether trichloroethylene is the agent involved and to investigate aspects of the physiology of injury utilizing a procedure which may be applicable to other long-term, low-level pollution studies.
Optical add/drop multiplexers for WDM communication systems (2002)

Wavelength-division multiplexing (WDM) is currently introduced worldwide into existing optical communication systems for capacity enhancement. OADM (optical add/drop multiplex) nodes are key elements of such systems, assuring network survivability by fast reconfiguration and enabling add/drop of WDM channels. OADM nodes comprising a variety of different OADM devices are developed within the ACTS project METON (Metropolitan Optical Network) for operation and comparative analysis in the Stockholm Gigabit Network. The paper will compare various OADM devices, highlight recent achievements, and discuss the potential and the limitations of the different approaches. The presentation comprises arrayed waveguides, Bragg gratings in fibers and in SiO/sub 2//Si waveguides, advanced InP-based interferometric structures and grating-assisted couplers. The advanced approaches will be discussed in detail and their characteristics will be compared to that of standard, commercially available OADMs such as Fabry-Perot interferometers or bulk optics. Cascading of SiO/sub 2//Si arrayed waveguide WDMs with a -3-dB passband of 1 nm has been tested in a recirculating loop at 10 Gbit/s. More than 40 WDMs could be passed before a significant penalty was introduced.
NASA Experience with Pogo in Human Spaceflight Vehicles (2008)

An overview of more than 45 years of NASA human spaceflight experience is presented with respect to the thrust axis vibration response of liquid fueled rockets known as pogo. A coupled structure and propulsion system instability, pogo can result in the impairment of the astronaut crew, an unplanned engine shutdown, loss of mission, or structural failure. The NASA history begins with the Gemini Program and adaptation of the USAF Titan II ballistic missile as a spacecraft launch vehicle. It continues with the pogo experienced on several Apollo-Saturn flights in both the first and second stages of flight. The defining moment for NASA s subsequent treatment of pogo occurred with the near failure of the second stage on the ascent of the Apollo 13 mission. Since that time NASA has had a strict "no pogo" philosophy that was applied to the development of the Space Shuttle. The "no pogo" philosophy lead to the first vehicle designed to be pogo-free from the beginning and the first development of an engine with an integral pogo suppression system. Now, more than 30 years later, NASA is developing two new launch vehicles, the Ares I crew launch vehicle propelling the Orion crew excursion vehicle, and the Ares V cargo launch vehicle. A new generation of engineers must again exercise NASA s system engineering method for pogo mitigation during design, development and verification.

Chemical Vapor Deposition of Tantalum Oxide from Tetraethoxo(β-diketonato)tantalum(V) Complexes (1999)

The complexes [Ta(OEt)4(β-diketonate)] (β-diketonate = acetylacetonate, 2; hexafluoroacetylacetonate, 3; 1,1,1-trifluoroacetylacetonate, 4; dipivaloylmethanate, 5; 2,2-dimethyl-6,6,7,7,8,8,8-heptafluoro-3,5-octanedionate, 6) are established as volatile liquid precursors for low-pressure chemical vapor deposition (CVD) of films of tantalum(V) oxide. They give thermal CVD at a slightly lower temperature than the commonly used precursor [{Ta(OEt)5}2], 1. In all cases, the CVD at 300−450 °C gives amorphous films of Ta2O5, which crystallize on annealing at 800 °C under oxygen. Promotion of Ta2O5 film formation is established using catalyst-enhanced CVD with a palladium precursor as “catalyst” and the minimum CVD temperature is then reduced to 200 °C.
When and Why Randomized Response Techniques (Fail To) Elicit the Truth (2018)

By adding random noise to individual responses, randomized response techniques (RRTs) are intended to enhance privacy protection and encourage honest disclosure of sensitive information. Empirical findings on their success in doing so are, however, mixed. In nine experiments, we show that the noise introduced by RRTs can make respondents concerned that innocuous responses will be interpreted as admissions, and as a result, yield prevalence estimates that are lower than direct questioning (Studies 1–4, 5A, & 6), less accurate than direct questioning (Studies 1, 3, 4B, & 5A), and even nonsensical (i.e., negative; Studies 3–6). Studies 2A and 2B show that the paradox is eliminated when the target behavior is socially desirable, even when it is merely framed as such. Study 3 shows the paradox is driven by respondents’ concerns over response misinterpretation. A simple modification designed to reduce concerns over response misinterpretation reduces the problem (Studies 4 & 5), particularly when such concerns are heightened (Studies 5 & 6).
Real-World Exhaust Emissions of Diesel Locomotives and Motorized Railcars during Scheduled Passenger Train Runs on Czech Railroads (2020)

The paper summarizes exhaust emissions measurements on two diesel-electric locomotives and one diesel-hydraulic railcar, each tested for several days during scheduled passenger service. While real driving emissions of buses decrease with fleet turnaround and have been assessed by many studies, there are virtually no realistic emissions data on diesel rail vehicles, many of which are decades old. The engines were fitted with low-power portable online monitoring instruments, including a portable Fourier Transform Infra Red (FTIR) spectrometer, online particle measurement, and in two cases with proportional particle sampling systems, all installed in engine compartments. Due to space constraints and overhead electric traction lines, exhaust flow was computed from engine operating data. Real-world operation was characterized by relatively fast power level transitions during accelerations and interleaved periods of high load and idle, and varied considerably among service type and routes. Spikes in PM emissions during accelerations and storage of PM in the exhaust were observed. Despite all engines approaching the end of their life, the emissions per passenger-km were very low compared to automobiles. Tests were done at very low costs with no disruption of the train service, yielded realistic data, and are also applicable to diesel-hydraulic units, which cannot be tested at standstill.
Interplay between BCL10, MALT1 and IκBα during T-cell-receptor-mediated NFκB activation (2010)

T-cell-receptor (TCR) signalling to NFkappaB requires the assembly of a large multiprotein complex containing the serine/threonine kinase CK1alpha, the scaffold protein CARMA1, the heterodimer BCL10-MALT1 (the CBM complex) and the IkappaB kinase complex (IKK). Although the mechanisms regulating recruitment and activation of IKK within the CBM microenvironment have been extensively studied, there is little understanding of how IKK subsequently binds and phosphorylates IkappaBalpha, the inhibitor of NFkappaB, to promote IkappaBalpha ubiquitylation and proteasomal degradation. Here, we show that BCL10, MALT1 and IKK inducibly associate with IkappaBalpha in a complex that is physically distinct from the early CK1alpha-CBM signalosome. This IkappaBalpha-containing complex probably maturates from the CBM, because siRNA-based knockdown of CARMA1, CK1alpha and BCL10 hampered its assembly, leading to a reduction in NFkappaB activation. By contrast, CK1alpha normally recruited both BCL10 and ubiquitylated species of MALT1 when IkappaBalpha levels were reduced. However, knockdown of IkappaBalpha led to an altered ubiquitylation profile of BCL10-MALT1 combined with a defect in MALT1 reorganisation within large cytoplasmic structures, suggesting that, following stimulation, IkappaBalpha might also participate in MALT1 recycling. Altogether, our data suggest a two-step mechanism to connect active IKK to IkappaBalpha, and further unveil a potential role for IkappaBalpha in resetting TCR-mediated signalling.
Enhanced diffusion of phosphorus at grain boundaries (1982)

Enhanced diffusion of phosphorus at grain boundaries in cast polycrystalline photovoltaic materials (Wacker, HEM, and Semix) was studied. It was found that the enhancements for the three materials were the same, indicating that the properties of boundaries are similar, even though they were grown by different techniques. In addition, it was observed that grain boundaries capable of enhancing the diffusion always have strong recombination activities. Both phenomena could be related to dangling bonds existing at the boundaries. The present study gives the first evidence that incoherent second order twins of 111/115-plane type are diffusion-active.
Field controlled thyristors-a new family of power semiconductors with advanced circuitry (2003)

Field-controlled thyristors (FCTs) exhibiting true normally-off characteristics without deterioration of the on-state are reported. Snubberless switching capability has been extended to 1200 V and 16 A (200 A/cm/sup 2/, dynamic avalanche). A novel latching mechanism, called current punchthrough, that limits the turn-off current is presented. Typical devise characteristics are reported for both a normally-on FCT with lifetime control (dV/dt=10 kV/ mu s) and a normally-off FCT without lifetime control (dV/dt=600 V/ mu s). The influence of the drive circuit (MOSFET-FCT and thyristor-FCT cascades) is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Back–Projection Pipeline (2021)

We propose a simple extension of residual networks that works simultaneously in multiple resolutions for the problem of image super-resolution. Our network design is inspired by the iterative back-projection algorithm and seeks the more difficult task of learning how to enhance images. Compared to similar approaches, we propose a novel solution to make back-projections run in multiple resolutions by using a data pipeline workflow. Features are updated at multiple scales in each layer of the network. The update dynamic through these layers includes interactions between different resolutions in a way that is causal in scale, and it is represented by a system of ODEs, as opposed to a single ODE in the case of ResNets.
The Origin Recognition Complex Marks a Replication Origin in the Human TOP1 Gene Promoter (2002)

The locations of the origin recognition complex (ORC) in mammalian genomes have been elusive. We have therefore analyzed the DNA sequences associated with human ORC via in vivo cross-linking and chromatin immunoprecipitation. Antibodies specific for hOrc2 protein precipitate chromatin fragments that also contain other ORC proteins, suggesting that the proteins form multisubunit complexes on chromatin in vivo. A binding region for ORC was identified at the CpG island upstream of the human TOP1 gene. Nascent strand abundance assays show that the ORC binding region coincides with an origin of bidirectional replication. The TOP1 gene includes two well characterized matrix attachment regions. The matrix attachment region elements analyzed contain no ORC and constitute no sites for replication initiation. In initial attempts to use the chromatin immunoprecipitation technique for the identification of additional ORC sites in the human genome, we isolated a sequence close to another actively transcribed gene (TOM1) and an alphoid satellite sequence that underlies centromeric heterochromatin. Nascent strand abundance assays gave no indication that the heterochromatin sequence serves as a replication initiation site, suggesting that an ORC on this site may perform functions other than replication initiation.
Akt: A Therapeutic Target in Hepatic Ischemia–Reperfusion Injury (2016)

The activation of Akt from the reviewed therapies has resulted in predictable reduction in hepatocyte damage using the previously mentioned measurements. In a clinical setting, these therapies could potentially be used in combination to achieve better outcomes in hepatic transplant patients. Evidence supporting reduced I/R injury through Akt activation warrants further studies in human clinical trials.
Review of electrical machine in downhole applications and the advantages (2008)

To enable safe, economical and environmentally acceptable solutions for improving oil and gas recovery from mature fields and for exploitation of deep and ultra-deep offshore reservoirs, new downhole technologies are required. Electrification of downhole applications has proven to be promising. This paper presents electrical machine in currently available or emerging downhole applications and their advantages. Permanent magnet machines are the trend for downhole applications.
Data Classification and Aggregation in Flexible Clothing Based on Cloud Computing Analysis (2022)

The intelligent clothing system involves a large number of acquisition processes. In general, this process includes data terminal acquisition, data cleaning, data processing and analysis. These devices can monitor the area covered by the network in real time. Even through the adjustment of system parameters, so as to improve the comfort of clothing. For example, in high temperature environment, through the system control to speed up the loss of body heat. On the contrary, in low temperature environment, through regulating control to reduce the body heat emission, prevent temperature loss. An analysis of body perception parameters is used to predict the outcome of a risk before it occurs. Thus improve the effectiveness of medical rescue. The work is to design an efficient monitoring network for local monitoring and share data with the terminal Numerical simulation proves that the design strategy in this article can improve the network throughput and process the data in the order of priority.
