Robust direct data‐driven controller tuning with an application to vehicle stability control (2017)

Summary In direct data‐driven controller tuning, a mathematical model of the plant is not needed, as the control law is directly derived from experimental data. Because the most widely used data‐driven techniques are based on the assumption that the underlying dynamics – albeit unknow – is linear, the performance of the resulting controller may not be acceptable with systems whose operating region vary along the time. In this paper, we discuss how to robustify linear data‐driven design by exploiting the features of scenario optimization. More specifically, we carry out a modified version of the well known virtual reference feedback tuning approach where probabilistic performance guarantees are given also when the current operating condition is different from the one observed in the controller identification experiment. We validate the proposed approach on a vehicle stability control problem, via a thorough simulation campaign on a multibody simulator. The experimental results show the effectiveness of the proposed approach in a complex real‐world setting. Copyright © 2017 John Wiley &amp; Sons, Ltd.
Distributed Applications for Collaborative Three-Dimensional Workspaces (2003)

This paper focuses on the distributed architecture of the collaborative threedimensional user interface management system, Studierstube. The system allows multiple users to experience a shared 3D workspace populated by multiple applications using see-through head-mounted displays or other presentation media such as projection systems. Building large, ubiquitous, or mobile workspaces requires distribution of applications over several hosts in varying and dynamic configurations. The system design is based on a distributed shared scene graph that alleviates the application programmer from explicitly considering distribution and that avoids a separation of graphical and application data. The idea of unifying all system data in the scene graph is taken to its logical consequence by implementing application instances as nodes in the scene graph. Through the distributed shared scene graph mechanism, consistency of scene graph replicas and the contained application nodes is assured. Dynamic configuration management is based on application migration between participating hosts and a spatial model of locales allowing dynamic workgroup management. We describe a number of experimental workspaces that demonstrate the use of these configuration management techniques.
NOVIZIATO DEL TASSO: II: LE RIME GIOVANILI PER LUCREZIA E IL «RINALDO» (2016)

L'atmosfera di candido entusiasmo da cui nasce il Gierusalemme si dirada rapidamente intorno al Tassino quand'egli si trasferisce da Vcnczia a Padova, per compiere i suoi studi universitari (1). Padova, da secoli cittadella gloriosa deiraristotelismo, e, come e noto (2), in questi anni, una delle capitali piu fervide, e forse la piu spregiudicata, del Rinascimento: nel suo Studio convengono scolari da ogni parte d'Europa ad ascoltare maestri illustri, quali il Sigonio, il Pic colomini, il Robortello, il Passero, mentre uomini di lettere e d'arte si raccolgono intorno a Sperone Speroni, che, discepolo del Pomponazzi e del Bembo e custode della tradizione degli Infiammati, e il regolatore supremo della vita culturale della citta.

Molybdate- and Tungstate-Exchanged Layered Double Hydroxides as Catalysts for 1O2 Formation:  Characterization of Reactive Oxygen Species and a Critical Evaluation of 1O2 Detection Methods (1999)

Layered double hydroxides (LDHs) with the formula [Mg0.7Al0.3(OH)2](NO3)0.3 were partially exchanged with MoO42- and WO42- and were used as heterogeneous catalysts for the decomposition of H2O2 into singlet molecular oxygen (1O2). The oxometalate anions are present on the LDH as monomeric, tetrahedral MO42- anions. With LDH−MoO42- and H2O2, 1O2 is by far the prevailing reactive oxygen species. EPR trapping detected a minor amount of free OH• radicals, but these do not appreciably contribute to product formation in olefin oxygenation. LDH−WO42- transforms H2O2 into 1O2 about 4 times slower than the Mo catalyst, and additionally effects mono-oxygen transfer to electron-rich substrates such as amines and olefins. Only for alkenes with very low β values, the Schenck hydroperoxidation dominates over the epoxidation in the W-catalyzed reactions. While most tests for 1O2 detection were designed for photosensitized reactions, the applicability of these methods to dark catalytic reactions is not always clear. Therefore, a series of common 1O2 detection methods was critically evaluated in the LDH−WO42- or LDH−MoO42- + H2O2 reactions. Isomer distributions in the olefin hydroperoxidation and detection of NIR luminescence are the most reliable and sensitive methods. Quenching or trapping methods that involve amines should not be used when the catalyst also effects mono-oxygenation.
Autoregressive superresolution microelectromechanical systems Fourier transform spectrometer (2019)

In this work, the application of the superresolution autoregressive (AR) model to enhance the resolution of the microelectromechanical systems (MEMS) Fourier transform infrared spectrometer (FTIR) spectrometer is studied theoretically and experimentally. The effect of the number of spectral lines, the spacing between the lines, the resolution of the MEMS FTIR spectrometer and the signal-to-noise ratio (SNR) on the prediction accuracy is addressed for different targeted prediction resolutions. The effect of the SNR on applying the AR model is studied. Then, the AR model is applied to experimental data obtained using the MEMS FTIR for the different cases of single spectral line, xenon lamp lines and gas cells containing different gas mixtures. It is found that enhancement up to 4× can obtained in the case of the single line, while an enhancement of about 2-2.5× can be obtained in the case of multilines without having false spectral lines.
Multidisciplinary Safety Recommendations After Tracheostomy During COVID‐19 Pandemic: State of the Art Review (2020)

Treatment of patients with a tracheostomy in the COVID-19 pandemic requires foresight and may rival procedural considerations in tracheostomy in their complexity. By considering patient-specific factors, mitigating transmission risks, optimizing the clinical environment, and detecting late manifestations of severe COVID-19, clinicians can ensure due vigilance and quality care.
Simulating localised cellular inflammation and substrate properties in a strain energy density based bone remodelling algorithm for use in modelling trauma (2018)

Bone responds to mechanical stimulus and a range of pre-existing finite element models have been suggested to reproduce the internal physiological structure of bone. Inflammation effects are not included in these models, yet inflammation is a key component of bone repair in trauma. Therefore, a model is proposed and tested here that extends these methods to include parameters that could be considered to represent the behaviour of bone remodelling when influenced by inflammation. The proposed model regulates remodelling based on findings from recent studies into the nature of heterotopic ossification, the formation of heterotopic bone, which have revealed information about the nature of bone after high levels of trauma. These parameters include consideration of the distance from the zone of trauma, the density of mesenchymal stem cells, and substrate stiffness as a trigger for cells becoming osteogenic. The method is tested on a two-dimensional plate model and shows that the new extended algorithm can produce a range of structures depending on inputs that could be used in the future to replicate physiological scenarios.
Nonlinear dynamics in an optical system with controlled two-dimensional feedback: Black-eye patterns and related phenomena (1998)

We present experimental and theoretical results of spontaneous optical pattern formation in a nonlinear optical system. The nonlinear optical system we considered had a controllable phase-only spatial Fourier filter placed in the system's diffractive feedback loop. A change in feedback field spatial spectral component phase resulted in a transition between dynamic regimes, as observed in both experiments and numerics. Patterns originating from interactions between spatial modes belonging to different instability bands (black-eye patterns, decagons, etc.) were observed, as well as localized states and shock traveling waves.
Search for squarks and gluinos in events with an isolated lepton, jets, and missing transverse momentum at s=13  TeV with the ATLAS detector (2017)

The results of a search for squarks and gluinos in final states with an isolated electron or muon, multiple jets and large missing transverse momentum using proton-proton collision data at a center-of-mass energy of $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ are presented. The data set used was recorded during 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of $36.1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. No significant excess beyond the expected background is found. Exclusion limits at 95% confidence level are set in a number of supersymmetric scenarios, reaching masses up to 2.1 TeV for gluino pair production and up to 1.25 TeV for squark pair production.
Coupled wave equations theory of surface-enhanced femtosecond stimulated Raman scattering (2016)

We present a coupled wave semiclassical theory to describe plasmonic enhancement effects in surface-enhanced femtosecond stimulated Raman scattering (SE-FSRS). A key result is that the plasmon enhanced fields which drive the vibrational equation of motion for each normal mode results in dispersive lineshapes in the SE-FSRS spectrum. This result, which reproduces experimental lineshapes, demonstrates that plasmon-enhanced stimulated Raman methods provide unique sensitivity to a plasmonic response. Our derived SE-FSRS theory shows a plasmonic enhancement of |gpu|(2)ImχR(ω)gst (2)/ImχR(ω), where |gpu|(2) is the absolute square of the plasmonic enhancement from the Raman pump, χR(ω) is the Raman susceptibility, and gst is the plasmonic enhancement of the Stokes field in SE-FSRS. We conclude with a discussion on potential future experimental and theoretical directions for the field of plasmonically enhanced coherent Raman scattering.
Toward quantum entanglement in a quantum-dot nanocavity (1999)

Our semiconductor normal-mode-coupling microcavities, each containing a single narrow-linewidth quantum well (QW), exhibit record many-oscillator vacuum-field Rabi splitting (VRS). The question addressed here is: can the vacuum field be increased sufficiently by reducing the cavity-mode volume, so that a single quantum dot can exhibit VRS similar to an atom in a high-finesse cavity? The quantum-dot nanocavity has two advantages: a length close to the theoretical minimum and a much larger dipole moment; these permit strong coupling without an ultra high-Q cavity even for such a short length.

Bilateral Force Feedback Control for a Vehicle-Type Tele-Mobility System (2013)

This paper discusses the development of a vehicle-type tele-mobility system, and proposes a novel control structure on the basis of bilateral control with dimensional scaling taking into account a braking effect. In the field of teleoperations of mobile systems, information on work objects at a remote site is necessary for precise and safe manipulations. Conventionally, audiovisual information is fed back to the operators. However, these approaches cannot fully deal with contact conditions owing to the lack of force information. To tackle this problem, a mobile-hapto has been proposed. In the configuration of this system, the master system is a joystick, whereas the slave system is a mobile robot. From the standpoint of the operability of mobile robots, the master system should comprise not only joysticks but also pedals and steering handle, similar to automobile systems. Furthermore, for actual manipulations, visual information is essential in addition to force information. The proposed system addresses the above requirements, and it is expected that the functionality of the mobile robot systems will be enhanced and facilitated. The applicability of the developed system and the proposed control structure are experimentally confirmed.
A MEMS Microphone in a FOWLP (2019)

This work presents a fully functional miniaturized MEMS microphone demonstrator assembled within a modified Fan Out Wafer Level Package (FOWLP) process chain. Core of the development is the adaption of the FOWLP-process to MEMS-microphones, which have not yet been fully processed in the wafer fab. Instead, these microphone chips contain non-released membranes making them sufficiently robust to withstand backend processes, such as laminating and molding. The membrane release itself is performed on the reconstituted mold-wafer and postponed to a later process step. Mechanical stress effects induced by the package onto the MEMS are limited to a minimum by the implementation of stress decoupling suspension structures on the MEMS die.
Design Parameters for Tuning the Type 1 Cu Multicopper Oxidase Redox Potential: Insight from a Combination of First Principles and Empirical Molecular Dynamics Simulations (2011)

The redox potentials and reorganization energies of the type 1 (T1) Cu site in four multicopper oxidases were calculated by combining first principles density functional theory (QM) and QM/MM molecular dynamics (MD) simulations. The model enzymes selected included the laccase from Trametes versicolor, the laccase-like enzyme isolated from Bacillus subtilis, CueO required for copper homeostasis in Escherichia coli, and the small laccase (SLAC) from Streptomyces coelicolor. The results demonstrated good agreement with experimental data and provided insight into the parameters that influence the T1 redox potential. Effects of the immediate T1 Cu site environment, including the His(N(δ))-Cys(S)-His(N(δ)) and the axial coordinating amino acid, as well as the proximate H(N)(backbone)-S(Cys) hydrogen bond, were discerned. Furthermore, effects of the protein backbone and side-chains, as well as of the aqueous solvent, were studied by QM/MM molecular dynamics (MD) simulations, providing an understanding of influences beyond the T1 Cu coordination sphere. Suggestions were made regarding an increase of the T1 redox potential in SLAC, i.e., of Met198 and Thr232 in addition to the axial amino acid Met298. Finally, the results of this work presented a framework for understanding parameters that influence the Type 1 Cu MCO redox potential, useful for an ever-growing range of laccase-based applications.
Engineering of Insulin Receptor Isoform-Selective Insulin Analogues (2011)

We have discovered a new class of IR isoform-selective insulin analogues with 2-4-fold differences in relative binding affinities for either the A or the B isoform of the IR compared to human insulin. Our results demonstrate that a mutation at position B25 alone or in combination with a mutation at position B27 in the insulin molecule confers IR isoform selectivity. Isoform-preferential analogues may provide new opportunities for developing insulin analogues with improved clinical benefits.
Selective Feticide in Twin Transfusion Syndrome Using Ultrasound-Guided Insertion of Thrombogenic Coils (1995)

Twin transfusion syndrome is a common complication of monozygotic twin pregnancies. Selective feticide is one of the many different aggressive and invasive therapies that has been suggested to improve an otherwise dismal perinatal outcome. The ideal method of selective feticide remains to be delineated for cases of twin transfusion syndrome that occur remote from term. We describe a case involving the use of intracardiac placement of thrombogenic coils to attempt selective termination.
Imaging-Based Screen Identifies Laminin 411 as a Physiologically Relevant Niche Factor with Importance for i-Hep Applications (2018)

Use of hepatocytes derived from induced pluripotent stem cells (i-Heps) is limited by their functional differences in comparison with primary cells. Extracellular niche factors likely play a critical role in bridging this gap. Using image-based characterization (high content analysis; HCA) of freshly isolated hepatocytes from 17 human donors, we devised and validated an algorithm (Hepatocyte Likeness Index; HLI) for comparing the hepatic properties of cells against a physiological gold standard. The HLI was then applied in a targeted screen of extracellular niche factors to identify substrates driving i-Heps closer to the standard. Laminin 411, the top hit, was validated in two additional induced pluripotent stem cell (iPSC) lines, primary tissue, and an in vitro model of α1-antitrypsin deficiency. Cumulatively, these data provide a reference method to control and screen for i-Hep differentiation, identify Laminin 411 as a key niche protein, and underscore the importance of combining substrates, soluble factors, and HCA when developing iPSC applications.
Thermosensitive and Cell-Adhesive Pluronic Hydrogels for Human Adipose-Derived Stem Cells (2007)

Pluronic F127 has received increasing attention over many years as drug delivery systems, biomaterials, and hydrogels for tissue engineering. In this study, we synthesized temperature-sensitive and cell-adhesive triblock F127 copolymers, in which Arg-Gly-Asp (RGD) peptide ligand was grafted to Pluronic F127-4-methacryloxyethyl trimellitic anhydride (4-META) to obtain F127-META-RGD. The chemical structures of the F127-META-RGD block copolymers were confirmed by FTIR, 1H and 13C NMR, and GPC. The resultant F127-META-RGD showed very similar thermosensitive behaviors to F127 and F127-META. The critical micelle temperature (CMT) of the F127 copolymers decreased in the order of F127 &lt; F127-META &lt; F127-META-RGD, whereas the particle size followed an opposite trend. Interactions between the F127 copolymers and adipose-derived stem cells (ASC) were evaluated in terms of cell adhesion and proliferation on the hydrogel. These thermosensitive RGD-grafted Pluronic hydrogels that display the enhanced cell adhesiveness, are expected to be useful as a functional injectable scaffold for tissue engineering.
Vibration energy harvesting from a helicopter transmission using Mn-doped relaxor ferroelectric single crystal (2021)

A multi-modal vibration energy harvester has been developed for use on a helicopter transmission. The harvester is based on a topology optimised spring-steel cantilever-beam, with a pair of [011] poled Mn-PMN-PZT relaxor ferroelectric single crystal (RFSC) disk transducers. Finite element modelling is used optimise the position and crystal orientation to maximise the harvester output. The harvester is applied to a Bell 206-B Kiowa helicopter main rotor transmission, which has three main vibration components at 1900 Hz, 2300 Hz, and 2500 Hz. Superposition of the three vibratory components produced maximum measured peak accelerations of 100g (where g is 9.81 m s <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> ). The harvester was mounted on the transmission and tested under near-operational conditions, with the transmission oil temperature reaching 86 degrees Celsius. During testing the harvester typically produced peak open-circuit output voltages of 12.8 V and 10.6 V for the left and right RFSC transducers respectively. With an optimised resistive load of 60,000 Ohms, the harvester generated a peak power of 2.37 mW from the multi-component vibrations present on the transmission casing.
Optimization of DNA Vaccines Through the Use of Molecular Adjuvants (2003)

Although the injection of DNA into tissues was originally reported in the 1950s, the technology has gained more attention in recent years as a safe means of mimicking in vivo protein production normally associated with natural infection (1-3). Nucleic acid or DNA inoculation is an important vaccination technique that delivers DNA constructs encoding specific immunogens directly into the host (4-11). These expression cassettes transfect the host cells, which become the in vivo protein source for the production of antigen. This antigen then is the focus of the resulting immune response. This vaccination technique is being explored as an immunization strategy against a variety of infectious diseases as well as cancer.
<title>Practical point-to-point free-space quantum key distribution over .5 km</title> (1999)

We have demonstrated point-to-point single-photon quantum key distribution over a free-space optical path of approximately 475 m under daylight conditions. This represents an increase of &gt; 1,000 times farther than any reported point-to-point demonstration, and &gt; 6 times farther than the previous folded path daylight demonstration. We expect to extend the daylight range to 2 km or more within the next few months. A brief description of the system is given here.
Photoresist stochastic defect generation depending on alkyl chain length and concentration of tetraalkylammonium hydroxide in alkali aqueous developer (2023)

Abstract The effects of photoresist dissolution on randomly occurring (“stochastic”) pattern defects in extreme ultraviolet (EUV) lithography were investigated. Specifically, the effects of the alkali concentration of two developers of different alkyl chain lengths; tetramethylammonium hydroxide and tetrabutylammonium hydroxide (TBAH) on stochastic defect generation were investigated for two typical EUV photoresists. In the case of the PHS-type photoresist, results show that stochastic defect generation was almost the same regardless of developer type, given the same developer concentration. For the hybrid-type photoresist, a decrease in stochastic defects was found with the application of the longer alkyl chain length TBAH developer. Results also suggest the existence of an optimum developer concentration. Such optimum developer concentration is considered to be affected by the balance between polarity and non-polarity of the photoresist and developer components.
Cross-layer design and analysis of a low power, high density STT-MRAM for embedded systems (2017)

STT-MRAM (Spin Transfer Torque Magnetic Random Access Memory) has attracted considerable attention of late since it is the most promising logic compatible nonvolatile memory that is suitable for advanced logic nodes (N28 and beyond) in terms of endurance, speed and power. Embedded STT-MRAM has thus been proposed as a candidate for emerging low standby-power connectivity systems such IoT (Internet-of-Things) and wearables. We utilize the high performance CoFeB based perpendicular MTJ (pMTJ) device to realize a low power and highly dense STT-MRAM array for such systems. This study is carried out on the TSMC 28nm technology node and includes a complete cross-layer design and analysis framework ranging from device modeling to circuit design, layout and system implementation. The process variations and temperature (PT) impact on the MTJ for the STT-MRAM design (and correspondingly the total energy consumption and performance of the system) is also analyzed. We report a ∼85% reduction in the energy consumption compared to the baseline SRAM based system for near negligible performance penalty (<5%).
