The CoronaSurveys System for COVID-19 Incidence Data Collection and Processing (2021)

CoronaSurveys is an ongoing interdisciplinary project developing a system to infer the incidence of COVID-19 around the world using anonymous open surveys. The surveys have been translated into 60 languages and are continuously collecting participant responses from any country in the world. The responses collected are pre-processed, organized, and stored in a version-controlled repository, which is publicly available to the scientific community. In addition, the CoronaSurveys team has devised several estimates computed on the basis of survey responses and other data, and makes them available on the project’s website in the form of tables, as well as interactive plots and maps. In this paper, we describe the computational system developed for the CoronaSurveys project. The system includes multiple components and processes, including the web survey, the mobile apps, the cleaning and aggregation process of the survey responses, the process of storage and publication of the data, the processing of the data and the computation of estimates, and the visualization of the results. In this paper we describe the system architecture and the major challenges we faced in designing and deploying it.
TREATMENT-RESPONSIVE SUBACUTE LIMBIC ENCEPHALITIS AND NMDA RECEPTOR ANTIBODIES IN A MAN (2008)

Disturbances of memory, behavior, cognition, and seizures can result from immune-mediated encephalitides. These disorders can be paraneoplastic or not and may associate with several antibodies.1 Recently, a treatment-responsive paraneoplastic encephalitis that associates with antibodies to NR1/NR2 heteromers of the NMDA receptor (NMDAR) was reported.2 Patients were young women with teratomas, usually of the ovary, who presented with prominent psychiatric symptoms, and less frequently with features of limbic encephalitis. We report a man with treatment-responsive limbic encephalitis and antibodies to NR1/NR2 heteromers.

### Case report.

For 3 months this 53-year-old man had progressive short-term memory deficits and disorientation that forced him to leave his job. During the month before hospital admission he had multiple episodes compatible with partial complex seizures. He had no past medical history of interest. The neurologic examination only revealed short-term memory deficits and impairment of temporal orientation. Blood cell count, general chemistry, B12, folic acid, thyroid function test, thyroglobulin antibodies, RPR, Lyme serology, antibodies to double stranded DNA, and SSA/Ro and SSB/La were unrevealing. CSF analysis showed 5 WBC/μL (100% lymphocytes) and normal glucose and protein concentration. Serum and CSF disclosed the same oligoclonal IgG bands. Paraneoplastic antineuronal and VGKC antibodies were negative. EEG demonstrated bilateral temporal lobe epileptic activity. MRI of the brain revealed noncontrast enhancing T2 and FLAIR hyperintensities involving the medial aspect of the temporal lobes and nonspecific hyperintensities in the frontal lobes (figure, A). Ultrasound of the testis, CT of the chest, abdomen and …

Revealing the structure of a catalytic combustion active-site ensemble combining uniform nanocrystal catalysts and theory insights (2020)

Supported metal catalysts are extensively used in industrial and environmental applications. To improve their performance, it is crucial to identify the most active sites. This identification is, however, made challenging by the presence of a large number of potential surface structures that complicate such an assignment. Often, the active site is formed by an ensemble of atoms, thus introducing further complications in its identification. Being able to produce uniform structures and identify the ones that are responsible for the catalyst performance is a crucial goal. In this work, we utilize a combination of uniform Pd/Pt nanocrystal catalysts and theory to reveal the catalytic active-site ensemble in highly active propene combustion materials. Using colloidal chemistry to exquisitely control nanoparticle size, we find that intrinsic rates for propene combustion in the presence of water increase monotonically with particle size on Pt-rich catalysts, suggesting that the reaction is structure dependent. We also reveal that water has a near-zero or mildly positive reaction rate order over Pd/Pt catalysts. Theory insights allow us to determine that the interaction of water with extended terraces present in large particles leads to the formation of step sites on metallic surfaces. These specific step-edge sites are responsible for the efficient combustion of propene at low temperature. This work reveals an elusive geometric ensemble, thus clearly identifying the active site in alkene combustion catalysts. These insights demonstrate how the combination of uniform catalysts and theory can provide a much deeper understanding of active-site geometry for many applications.
Hybridizing Conversational and Clear Speech to Investigate the Source of Increased Intelligibility in Speakers With Parkinson's Disease (2014)

Not all production changes accompanying clear speech explain its improved intelligibility. Suprasegmental adjustments contributed to intelligibility improvements when segmental adjustments, as inferred from vowel space area, were not robust. Hybridization can be used to identify acoustic variables explaining intelligibility variation in mild dysarthria secondary to PD.
Continuous-Domain Formulation of Inverse Problems for Composite Sparse-Plus-Smooth Signals (2021)

We present a novel framework for reconstructing 1D composite signals, where one component is sparse and the other is smooth, based on a finite number of linear measurements. We formulate the reconstruction problem as a continuous-domain regularized inverse problem with multiple penalties, and we prove that solutions of this problem are of the desired form (i.e., the sum of a sparse and smooth components). We then discretize this problem using B-spline bases, which yields a discrete problem that can be solved using standard discrete algorithms. This discretization is exact in the sense that we are solving the continuous-domain problem over the search space specified by our bases without any discretization error. We propose a complete algorithmic pipeline and demonstrate its feasibility on some simulated data.
Standardized Dynamic Reconfiguration of Control Applications in Industrial Systems (2014)

Industrial areas like manufacturing, logistics and power systems require highly flexible and adaptable control solutions in order to fulfill future requirements. An industrial automation system has to provide technologies, concepts and mechanisms allowing the adaption of control logic during operation. Proper engineering approaches as well as execution environments with dynamic reconfiguration capabilities are needed to turn this vision into reality. This article provides an overview of applying the IEC 61499 reference model for distributed automation as basis for a standard-compliant reconfigurable method in industrial environments. It covers the modeling and engineering of reconfiguration applications and their execution on distributed embedded controllers using IEC 61499. This approach significantly increases engineering efficiency and reuse in component-based design of industrial automation and control applications. A special focus of this contribution is the discussion of implemented industrial use cases from the manufacturing, robotics and power systems domain.
Efficient and extensible algorithms for multi query optimization (2000)

Complex queries are becoming commonplace, with the growing use of decision support systems. These complex queries often have a lot of common sub-expressions, either within a single query, or across multiple such queries run as a batch. Multiquery optimization aims at exploiting common sub-expressions to reduce evaluation cost. Multi-query optimization has hither-to been viewed as impractical, since earlier algorithms were exhaustive, and explore a doubly exponential search space. In this paper we demonstrate that multi-query optimization using heuristics is practical, and provides significant benefits. We propose three cost-based heuristic algorithms: Volcano-SH and Volcano-RU, which are based on simple modifications to the Volcano search strategy, and a greedy heuristic. Our greedy heuristic incorporates novel optimizations that improve efficiency greatly. Our algorithms are designed to be easily added to existing optimizers. We present a performance study comparing the algorithms, using workloads consisting of queries from the TPC-D benchmark. The study shows that our algorithms provide significant benefits over traditional optimization, at a very acceptable overhead in optimization time.
Rod Laser – The first laser was a rod laser (2005)

Laser technology is relatively young. The first laser was built in 1960 by Maiman at AT&T Labs in the USA. It was a rod-shaped ruby laser, this arrangement having been chosen for its favourable symmetry (Fig. 1). Starting from this device, the technology of solid-state lasers developed rapidly. The predominantly used geometric shape for the laser medium was the rod. Many different solidstate materials have been tested.

Improvement of Turboshaft Restart Time Through an Experimental and Numerical Investigation (2021)

Abstract Inflight shutdown of one engine for twin-engine helicopters has proven beneficial for fuel consumption. A new flight mode is then considered, in which one engine is put into sleep mode while the second engine runs at nominal load. The ability to restart the engine in sleep mode is then critical for safety reasons. Indeed, the certification of this flight mode involves ensuring a close-to-zero failure rate for in-flight restarts and a fast restart capability of the shutdown engine (focus of this paper). Fast restart capability is necessary in case of a failure of the operating engine. Indeed, there is no more power available, and the helicopter can lose up to 15–20 meters per second during autorotation. The restart time becomes a critical parameter to limit the loss of altitude. The aim of the paper is to assess the potential restart time saving using an approach combining test rig data analysis and numerical results generated by a thermodynamic model able to simulate at low rotational speed. It is important to understand the detailed phenomenology of the startup process and the various subsystems involved, first to highlight the influencing parameters and then to establish an exhaustive listing of the possible time optimizations. The results of this study show that a fast restart going from sleep mode to max power speed can be up to 60% faster than a conventional restart going from sleep mode to idle speed, which is significantly faster.
Crystal Structures of Lanthanide(III) Complexes with Cyclen Derivative Bearing Three Acetate and One Methylphosphonate Pendants (2005)

A series of lanthanide(III) complexes formulated as M[Ln(Hdo3ap)].xH(2)O (M = Li or H and Ln = Tb, Dy, Er, Lu, and Y) with the monophosphonate analogue of H(4)dota, 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic-10-methylphosphonic acid (H(5)do3ap), was prepared in the solid state and studied using X-ray crystallography. All of the structures show that the (Hdo3ap)(4-) anion is octadentate coordinated to a lanthanide(III) ion similarly to the other H(4)dota-like ligands, i.e., forming O(4) and N(4) planes that are parallel and have mutual angle smaller than 3 degrees . The lanthanide(III) ions lie between these planes, closer to the O(4) base than to the N(4) plane. All of the structures present the lanthanide(III) complexes in their twisted-square-antiprismatic (TSA) configuration. Twist angles of the pendants vary in the range between -24 and -30 degrees, and for each complex, they lie in a very narrow region of 1 degree. The coordinated phosphonate oxygen is located slightly above (0.02-0.19 Angstroms) the O(3) plane formed with the coordinated acetates. A water molecule was found to be coordinated only in the terbium(III) and neodymium(III) complexes. The bond distance Tb-O(w) is unusually long (2.678 Angstroms). The O-Ln-O angles decrease from 140 degrees [Nd(III)] to 121 degrees [Lu(III)], thus confirming the increasing steric crowding around the water binding site. A comparison of a number of structures of Ln(III) complexes with DOTA-like ligands shows that the TSA arrangement is flexible. On the other hand, the SA arrangement is rigid, and the derived structural parameters are almost identical for different ligands and lanthanide(III) ions.
The Unified Model-Based Design: how not to choose between Scade and Simulink (2016)

Software projects using Simulink or Scade use in fact a subset of Simulink or Scade. The 'alignment' of these two subsets gives rise to a new concept, the 'Unified MBD', interesting in two respects: on the academic side, it gives a simple semantics to our subset of Simulink, and on the industrial side, it permits at almost no cost the double-skill Scade/Simulink for software and system engineers. For the data-flow part, the unified subset is simply the 'clockless' part of the Scade/Simulink intersection. For the control-flow part, the unified subset is much more restricted, but the fundamental aspect is that it strictly conforms to a well-known paradigm called 'mode-automatas'.
A transformer-less interleaved four-phase current-fed converter with new voltage multiplier topology (2013)

In this paper, a transformer-less interleaved four-phase current-fed converter with high voltage gain and reduced semiconductor voltage stress is proposed. The proposed topology utilizes input-parallel output-series configuration for providing a much higher voltage gain without adopting an extreme large duty cycle. The proposed converter can not only achieve high step-up voltage gain but also reduce the voltage stress of both active switches and diodes. This will allow one to choose lower voltage rating MOSFETs and diodes to reduce both switching and conduction losses. In addition, due to the charge balance of the blocking capacitor, the converter features automatic uniform current sharing characteristic of the four interleaved phases for voltage boosting mode without adding extra circuitry or complex control methods. The operation principle and steady analysis of the proposed converter are discussed. Finally, some simulation and experimental results are also presented to demonstrate the effectiveness of the proposed converter.
Silicane as an Inert Substrate of Silicene: A Promising Candidate for FET (2014)

Opening up a band gap without lowering high carrier mobility and finding a suitable substrate material are a challenge for designing silicon-based nanodevices. Using density functional theory calculations incorporating vdW corrections, we find that the semiconducting silicane monolayer is free of dangling bonds, providing an ideal substrate for silicene to sit on. The nearly linear band dispersion character of silicene with a sizable band gap (44–61 meV) opening is obtained in all heterobilayers (HBLs). We also find that the effective masses of electrons and holes near the Dirac point (ranging from 0.033 to 0.045m0) are very small in HBLs, and thus high carrier mobility (105cm2 V–1 s–1) of silicene is expected. These characteristics of HBLs can be flexibly modulated by applying bias voltage or strain, suitable for the high-performance FET channel operating at room temperature.
Spectral features of the wake and power fluctuations of model wind turbines under low-level jets (2022)

Laboratory experiments are conducted to inspect the modulation of model low-level-jet (LLJ) velocity profiles on the wake of a model wind turbine and power output fluctuations and a spectral structure of a simple two-turbine system in an aligned configuration. The scenario with a canonical incoming turbulent boundary layer profile is included for comparison. The results reveal a significant effect of the relative height of the LLJ peak velocity on the near and intermediate wake and power output fluctuations. Those effects are more notorious with the LLJ peak velocity coincident with the turbine top tip. The strong mean shear right above the wake promotes enhanced vertical transport and generation of energetic coherent motions. In particular, the near and intermediate wake velocity spectra showed a robust local signature with a streamwise length on the order of ∼4 times the rotor diameter. Although this shear layer did not significantly affect the spectrum of the power output fluctuations, the relatively large-scale velocity fluctuations may affect wind turbines' downwind in arrays.
Hodgkin's Lymphoma in Adolescents (2006)

Adolescents and young adults with HL have similar baseline characteristics and achieve similar outcomes when treated with the same protocols. The use of adult treatment protocols is a safe and effective strategy for treating adolescents with HL.
Investigations on Material and Mechanical Properties, Air‐Permeation Behavior and Filtration Performance of Mullite‐Bonded Porous S i C Ceramics (2013)

A theoretical relation between processing parameters and porosity (29–56%) of mullite‐bonded porous S i C ceramics was derived and validated with experimental data. Porosity‐dependent variation of fracture strength (9–34 MPa) and elastic modulus (7–28 GPa) was explained by the minimum solid area model. At room temperature, the D arcian, k 1 (1.2 × 10 −13 –1.6 × 10 −12 m 2 ) and the non‐ D arcian, k 2 (4.6 × 10 −9 –2.7 × 10 −7 m) permeability coefficients showed linear variation with porosity. Tests conducted up to 650°C indicated an increase in k 1 with temperature and a reverse trend for k 2 . Airborne N a C l nanoparticle filtration tests showed good performance of S i C ceramics with fractional collection efficiency of &gt;99% at 46–56% porosity levels.
Migrainous Vertigo: Results of Caloric Testing and Stabilometric Findings (2009)

Our results indicate that vestibular functional damage may occur in all vestibular pathways; central and peripheral signs are equally represented. Our data are not inconsistent with the hypothesis that a vestibulo-spinal dysfunction is the causal factor for the posturographic results. Moreover, the Visual Romberg Index is significant for increased visual cue dependence in migraineurs.
Mycophenolate mofetil and skin diseases (2005)

Mycophenolate mofetil (MMF) is an immunosuppressive drug the efficiency of which has been established in renal transplantation. Recent studies suggest that it may also be effective in the treatment of variant skin diseases especially if the skin lesions are triggered by lymphocytes. Studies have shown efficacy in autoimmune bullous dermatoses, atopic dermatitis and psoriasis. However, there are no placebo-controlled trials that support the use of MMF as first line therapy in these skin diseases.
Frame structure of broad-band wireless communication system using high gain directional antennas (2002)

The frame structure of the future broad-band wireless multimedia communication system using millimeter wave frequencies is investigated. Both portability and small power consumption of the terminal are realized by the gain of base station (BS) antenna. The frame structure in this system is constructed in terms of medium access control (MAC), user data slot allocation, and call control. In addition, tracking of mobile terminals (MTs) and wireless path selection (WPS) are considered for the sake of narrow beam width of the high gain antenna. The performances of WPS taking into account both the MT tracking and the shadowing caused by human bodies are evaluated by computer simulation. Furthermore, the effects of the overlap of covered area by-each BS are evaluated. The throughput performances of two configurations of whose overlap differs are compared. The results show that the proposed frame structure enables the site diversity configuration to become effective even for MTs.

Superresolution through regular sampling: Theory and applications (2018)

Estimating fine-scale spectral information from coarse-scale measurements is an important issue in many signal processing applications. The problem of superresolution is therefore receiving considerable attention. We offer a technique that allows to overcome the Shannon-Nyquist sampling rate limitation and at the same time may improve the conditioning of the numerical linear algebra problems involved. The technique is exploiting aliasing rather than avoiding it and maintains a regular sampling scheme [3]. It relies on the concept of what we call an identification shift [1, 2], which is the additional sampling at locations shifted with respect to the original locations in order to overcome any ambiguity in the analysis. Neither the original sampling nor the identification shift need to respect the Shannon-Nyquist sampling theorem. So far the technique shows great potential in magnetic resonance spectroscopy, vibration analysis, echolocation, music signal processing, ISAR radar problems, and DOA or direction of arrival.
