Multisensor integration using neuron computing for land-vehicle (2003)

Most of the present navigation sensor integration techniques are based on Kalman-filtering estimation procedures. Although Kalman filtering represents one of the best solutions for multisensor integration, it still has some drawbacks in terms of stability, computation load, immunity to noise ef- fects and observability. Furthermore, Kalman filters perform adequately only under certain predefined dynamic models. Neuron computing, a technology of artificial neural network (ANN), is a powerful tool for solving nonlinear problems that involve mapping input data to output data without having any prior knowledge about the mathematical process involved. This article suggests a multisensor integration approach for fusing data from an inertial navigation system (INS) and differential global positioning system (DGPS) hardware utilizing multilayer feed- forward neural networks with a back propagation learning algorithm. In addition, it addresses the impact of neural network (NN) parameters and random noise on positioning accuracy.

Amplification of the pulmonary vasodilatory response to inhaled iloprost by subthreshold phosphodiesterase types 3 and 4 inhibition in severe pulmonary hypertension (2002)

These data support the principle that subthreshold selective phosphodiesterase types 3 and 4 inhibition amplifies the lung vasodilatory response to inhaled iloprost, with minute doses being sufficient via the inhalative route.

Primed Immune Responses Triggered by Ingested Bacteria Lead to Systemic Infection Tolerance in Silkworms (2015)

In the present study, we examined whether microorganisms collaterally ingested by insects with their food activate the innate immune system to confer systemic resistance against subsequent bacterial invasion. Silkworms orally administered heat-killed Pseudomonas aeruginosa cells showed resistance against intra-hemolymph infection by P. aeruginosa. Oral administration of peptidoglycans, cell wall components of P. aeruginosa, conferred protective effects against P. aeruginosa infection, whereas oral administration of lipopolysaccharides, bacterial surface components, did not. In silkworms orally administered heat-killed P. aeruginosa cells, P. aeruginosa growth was inhibited in the hemolymph, and mRNA amounts of the antimicrobial peptides cecropin A and moricin were increased in the hemocytes and fat body. Furthermore, the amount of paralytic peptide, an insect cytokine that activates innate immune reactions, was increased in the hemolymph of silkworms orally administered heat-killed P. aeruginosa cells. These findings suggest that insects sense bacteria present in their food by peptidoglycan recognition, which activates systemic immune reactions to defend the insects against a second round of infection.
RePro3D: full-parallax 3D display with haptic feedback using retro-reflective projection technology (2011)

We propose a novel full-parallax three-dimensional (3D) display system-RePro3D-that is suitable for interactive 3D applications with haptic feedback.Our approach is based on the retro-reflective projection technology in which several images projected from a projector array are displayed on a retro-reflective screen. When viewers view the screen through a half mirror, they see, without the aid of glasses, a 3D image superimposed in real space. RePro3D has a sensor function that recognizes user input; therefore, it can support some interactive features such as manipulation of 3D objects. In addition, a wearable haptic device, which is a part of our system, provides the user with a sensation of having touched the 3D image. In this paper, we describe the optical system of the high-density projector array used in RePro3D. Then, we describe the development of a prototype of RePro3D. The prototype is used to demonstrate that our system displays full-parallax images superimposed in real space from 42 different viewpoints. The proposed system enables a user to physically interact with the 3D image with haptic feedback.

Rhodium-Catalyzed <i>Endo</i>-Selective Epoxide-Opening Cascades: Formal Synthesis of (−)-Brevisin (2015)

[Rh(CO)2Cl]2 is as an effective catalyst for endo-selective cyclizations and cascades of epoxy-(E)-enoate alcohols, thus enabling the synthesis of oxepanes and oxepane-containing polyethers from di- and trisubstituted epoxides. Syntheses of the ABC and EF ring systems of (-)-brevisin via all endo-diepoxide-opening cascades using this method constitute a formal total synthesis and demonstrate the utility of this methodology in the context of the synthesis of marine ladder polyether natural products.

Invasion of mammalian host cells by <i>Plasmodium</i> sporozoites (2002)

Malaria is transmitted through the bite of an infected mosquito, which introduces Plasmodium sporozoites into the mammalian host. Sporozoites rapidly reach the liver of the host where they are sequestered, a process probably mediated by circumsporozoite (CS) protein. Once in the liver, sporozoites migrate through several hepatocytes by breaching their plasma membranes before infecting a final hepatocyte with formation of a vacuole around the sporozoite, where development occurs into blood stage parasites. We propose that migration through several host cells activates sporozoites for ultimate productive invasion. This migration triggers sporozoite exocytosis, which is necessary for hepatocyte invasion, probably because it provides molecules, such as thrombospondin-related anonymous protein (TRAP), likely required for sporozoite invasion with the formation of a vacuole. How sporozoites migrate from the skin to the liver and invade hepatocytes remains unclear. Understanding this initial stage of malaria is crucial for the development of new approaches against the disease.
Multiphoton microscopy by multiexcitonic ladder climbing in colloidal quantum dots (2009)

Depth resolved multiphoton microscopy is performed by collecting the fluorescent emission of two-exciton states in colloidal quantum dots. The biexciton is formed via two sequential resonant absorption events. Due to the large absorption cross-section and the long lifetime of the intermediate (singly excited) state, unprecedented low excitation energy and peak powers (down to 10<sup>5</sup>W/cm<sup>2</sup>) are required to generate this nonlinear response. Depending on the quantum dot parameters, the effective two-photon cross section can be as large as 10<sup>10</sup> GM, orders of magnitude higher than for nonresonant excitation. The biexciton emission can be differentiated from that of the singly excited state by utilizing its different transient dynamics. Alternate methods for discrimination are also discussed. This system is ideal for performing three-dimensional microscopy using low excitation power. Moreover, it enables to perform multiphoton imaging even with near-infrared emitting quantum dots, which are highly compatible with imaging deep into a scattering tissue. The depth resolution of our microscope is shown to be equivalent to a standard two-photon microscope. The system also shows slow saturation due to the contribution of higher (triply and above) excited states to the emitted signal.
RF Spectrum Analyzer for Pulsed Signals: Ultra-Wide Instantaneous Bandwidth, High Sensitivity, and High Time-Resolution (2016)

We report on the experimental demonstration of a multi-gigahertz bandwidth RF spectrum analyzer based on spectral hole burning in a 3 K-cooled rare-earth ion-doped crystal. We implemented the so-called “rainbow” architecture in which the optically carried spectral components of the incoming signal are angularly separated by the crystal, and are then acquired with a pixelated photo-detector. With this setup, we have been able to monitor and record the spectrum of complex microwave signals over an instantaneous bandwidth above 20 GHz, with a time resolution below 100 μs, 400 resolvable frequency components and a 100% probability of intercept. RF pulsed signals in the μs range are perfectly analyzed with this high time-resolved set-up. The best achievable sensitivity for pulsed signals is computed and compared with another spectral hole burning technique.

Toward realistic binaural auralizations – perceptual comparison between measurement and simulation-based auralizations and the real room for a classroom scenario (2021)

In order to make full use of their potential to replace experiments in real rooms, auralizations must be as realistic as possible. Recently, it has been shown that for speech, head-tracked binaural auralizations based on measured binaural room impulse responses (BRIRs) can be so realistic, that they become indistinguishable (or nearly so) from the real room [1, 2]. In the present contribution, perceptual comparisons between the auralized and the real room are reported for auralizations based both on measured and simulated BRIRs. In the experiment, subjects sitting in the real room rated the agreement between the real and the auralized room with respect to a number of attributes. The results indicate that for most attributes, the agreement between the auralized and the real room can be very convincing (better than 7.5 on a nine-point scale). This was not only observed for auralizations based on measured BRIRs, but also for those based on simulated BRIRs. In the scenario considered here, the use of individual head-related impulse responses (HRIRs) does not seem to offer any benefit over using HRIRs from a head-and-torso-simulator.

Burnout: A Wearable System for Unobtrusive Skeletal Muscle Fatigue Estimation (2016)

Skeletal muscles are pivotal for sports and exercise. However, overexertion of skeletal muscles causes muscle fatigue which can lead to injury. Consequently, understanding skeletal muscle fatigue is important for injury prevention. Current ways to estimate exhaustion revolve around self-estimation or inference from such sensors as force sensors, electromyography e.t.c. These methods are not always reliable, especially during isotonic exercises. Toward this end, we present Burnout - a wearable system for quantifying skeletal muscle fatigue in an exercise setting. Burnout uses accelerometers to sense skeletal muscle vibrations. From these vibrations, Burnout obtains a region based feature (R- Feature), in the case of this work, the region mean power frequency (R-MPF) gradient to correlate the sensed vibrations to a known ground truth measure of skeletal muscle fatigue, i.e., Dimitrov's spectral fatigue index gradient. We evaluate Burnout on the biceps and quadriceps of 5 healthy participants through four different exercises, collected in a real world environment. Our results show that by using this R-MPF feature on our real world data set, Burnout is able to reduce the error of estimating the ground truth fatigue index gradient by up to 50% on average compared to using the standard MPF feature.
FREESTYLE SWIMMING: AN INSIGHT INTO PROPULSIVE AND RESISTIVE MECHANISMS (2012)

The mechanisms behind propulsion and drag generation in swimming have proven difficult to accurately and comprehensively measure. With fluid effects being the major contributing factor for swimming performance, the ability to accurately determine these effects is of great importance. Computational Fluid Dynamics (CFD) modelling provides a solution to this problem. CFD can not only quantify the net effect of the forces acting on a swimmer, but also that observed at each individual segment. CFD modelling allows complex fluid flow regimes and geometry to be simulated. The results of a CFD analysis allowed for the distribution of the forces across the body throughout the freestyle stroke to be examined. The results of this analysis include an increased level of foundational knowledge with applied outcomes that may be used to improve swimming performance.
INACTIVATION OF ALDEHYDE DEHYDROGENASE BY NITROGLYCERIN IN THE PRESENCE AND ABSENCE OF LIPOIC ACID AND DIHYDROLIPOIC ACID. IMPLICATIONS FOR THE PROBLEM OF DIFFERENTIAL EFFECTS OF LIPOIC ACID IN VITRO AND IN VIVO. (2016)

Lipoic acid (LA-(SS), LA) and its reduced form - dihydrolipoic acid DHLA-(SH)2, DHLA) are synthesized mainly in the mammalian liver. In this study, we investigated in viti the inactivation of yeast aldehyde dehydrogenase (ALDH) by nitroglycerin (GTN) in the presence and absence of LA and DHLA. In vivo studies were performed to answer the question whether LA administered jointly with GTN for 8 days will affect the ALDH activity in the rat liver. The results indicated that in vito both LA and DHLA restored and protected ALDH activity against GTN-induced inactivation, while treatment of rats with LA and GTN in combination did not provide any protection against GTN-induced ALDH inhibition. In summary, the obtained results seem to confirm earlier reports indicating the differential effects of LA in vitio and in vivo.
Primary extranodal lymphoma of skeletal muscles: a report of four cases. (1998)

Approximately one-fourth of non-Hodgkin's lymphomas originate in extranodal sites. True primary involvement of soft tissues is quite uncommon and only a few well-documented cases are reported in the literature. We report four cases of primary skeletal muscle lymphoma. Three of the four cases presented with a diffuse large B-cell lymphoma. The clinical history of two cases confirmed that soft tissue masses should be promptly biopsied, since the differential diagnosis comprises benign lesions, as well as sarcoma, primary or metastatic carcinoma, melanoma and lymphoma. As lymphomas have to be treated primarily according to the tumour histology and disease extent, treatment of primary skeletal muscle lymphomas must be planned with these factors in mind. For patients presenting with diffuse large cell histology, a CHOP-like regimen alone or a combined modality with radiotherapy seem to be proper approaches.
Large-bite diboranes for the μ(1,2) complexation of hydrazine and cyanide (2018)

As part of our interest in the chemistry of polydentate Lewis acids as hosts for diatomic molecules, we have investigated the synthesis and coordination chemistry of bidentate boranes that feature a large boron-boron separation. In this paper, we describe the synthesis of a new example of such a diborane, namely 1,8-bis(dimesitylboryl)triptycene (<b>2</b>) and compare its properties to those of the recently reported 1,8-bis(dimesitylboryl)biphenylene (<b>1</b>). These comparative studies reveal that these two diboranes feature some important differences. As indicated by cyclic voltammetry, <b>1</b> is more electron deficient than <b>2</b>; it also adopts a more compact and rigid structure with a boron-boron separation (4.566(5) Å) shorter by ∼1 Å than that in <b>2</b> (5.559(4) Å). These differences appear to dictate the coordination behaviour of these two compounds. While <b>2</b> remains inert toward hydrazine, we observed that <b>1</b> forms a very stable μ(1,2) hydrazine complex which can also be obtained by phase transfer upon layering a solution of <b>1</b> with a dilute aqueous hydrazine solution. The stability of this complex is further reflected by its lack of reaction with benzaldehyde at room temperature. We have also investigated the behaviour of <b>1</b> and <b>2</b> toward anions. In MeOH/CHCl<sub>3</sub> (1/1 vol) both compounds selectively bind cyanide to form the corresponding μ(1,2) chelate complexes with a B-C[triple bond, length as m-dash]N-B bridge at their cores. Competition experiments in protic media show that the anionic cyanide complex formed by <b>1</b> is the most stable, with no evidence of decomplexation even in the presence of (C<sub>6</sub>F<sub>5</sub>)<sub>3</sub>B.
&lt;i&gt;In-situ&lt;/i&gt; Mass Spectroscopic Analysis of Glucose Decomposition under Hydrothermal Condition: Quantitative Analysis for Reaction Kinetics (2017)

Quantitative in-situ analysis by mass spectroscopic (MS) method was developed and designed in order to elucidate the decomposition kinetics of glucose under hydrothermal conditions. Briefly, the proposed methodology employed a quadrupole mass analyzer coupled with a tubular batch reactor via custom-built connection fittings. At first, the hydrothermal treatment of glucose was conducted at temperatures ranging from 140 to 220 °C with reaction times between 2.5 min and 20 min. Liquid product obtained after the hydrothermal process was quantitatively analyzed with a mass analyzer and a high-performance liquid chromatography (HPLC) analyzer. The in-situ MS analysis revealed that the decomposition rate of glucose was enhanced at higher temperatures. The results also showed the presence of 5-hydroxymethylfurfural and other low-molecular-weight acids whose concentrations increased when the temperature increased to 180 °C and higher. A reaction pathway of glucose was developed, and the reaction rate constants were determined assuming first-order reactions.
