<title>Designing a user interface for service operations of an intelligent mobile manipulator</title> (1997)

User interfaces play an increasingly important role in robot applications. This paper presents the design and implementation of a multi-modal user interface for a mobile manipulator, consisting of an autonomous vehicle with a manipulator on it. It is capable of navigating in a real world and doing useful manipulations. The system is intended to provide services for handicapped people. The user interface is crucial for such a user to benefit from the services. The user interface designed for the system makes advantage of multimedia technology and combines graphics, speech and visualization into a coherent multi-modal interface. It serves as a user command interpreter, robot monitor and simulator. A user-centered design approach is adopted for enhanced understandability and usability.
Choosing the best heuristic for seeded alignment of DNA sequences (2006)

Practical seed design requires careful attention to the properties of the alignments being sought. For noncoding DNA sequences, seeds that use transition information, especially BLASTZ-style seeds, are particularly useful. The Mandala seed design software can be found at http://www.cse.wustl.edu/~yanni/mandala/.
On the Workspace of Electromagnetic Navigation Systems (2022)

In remote magnetic navigation, a magnetic navigation system is used to generate magnetic fields to apply mechanical wrenches to steer a magnetic object. This technique can be applied to navigate untethered micro- and nanorobots, as well as tethered magnetic surgical tools for minimally invasive medicine. The design and characterization of these systems have been extensively investigated over the past decade. The determination of the region in space in which these systems can operate has yet to be formalized within the research community. This region is commonly referred to as the “workspace” and constitutes a central concept for any class of robotic system. We focus on magnetic navigation systems comprised of electromagnets and propose a first set of definitions for a magnetic workspace, a methodology to determine it, and evaluation metrics to analyze its characteristics. Our methodology and tools are illustrated with several examples of planar and spatial electromagnetic magnetic navigation systems for both didactic and realistic navigation scenarios.
Unity yield of deterministically positioned quantum dot single photon sources (2022)

We report on a platform for the production of single photon devices with a fabrication yield of 100%. The sources are based on InAsP quantum dots embedded within position-controlled bottom-up InP nanowires. Using optimized growth conditions, we produce large arrays of structures having highly uniform geometries. Collection efficiencies are as high as 83% and multiphoton emission probabilities as low as 0.6% with the distribution away from optimal values associated with the excitation of other charge complexes and re-excitation processes, respectively, inherent to the above-band excitation employed. Importantly, emission peak lineshapes have Lorentzian profiles indicating that linewidths are not limited by inhomogeneous broadening but rather pure dephasing, likely elastic carrier-phonon scattering due to a high phonon occupation. This work establishes nanowire-based devices as a viable route for the scalable fabrication of efficient single photon sources and provides a valuable resource for hybrid on-chip platforms currently being developed.
Tissue Distribution and Penetration of Isavuconazole at the Site of Infection in Experimental Invasive Aspergillosis in Mice with Underlying Chronic Granulomatous Disease (2019)

Isavuconazole, the active moiety of the prodrug isavuconazonium sulfate, has potent activity against a wide spectrum of fungal pathogens and is approved for the treatment of invasive aspergillosis, yet little is known about the tissue penetration of isavuconazole at the target sites of infection. Here, we explored the spatial and quantitative distribution of isavuconazole in tissue lesions in experimental pulmonary aspergillosis established in mice with chronic granulomatous disease (CGD) (gp91<sup>phox-</sup>). Matrix-assisted laser desorption ionization mass spectrometry imaging (MALDI-MSI) and laser capture microdissection (LCM)-directed high-pressure liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) were used to analyze infected lungs and brain tissues collected 1, 3, 6, and 24 h after a single oral administration of the prodrug at a dose of 256 mg/kg of body weight (corresponding to 122.9 mg/kg of isavuconazole). Drug enrichment within granulomatous lesions was observed in lung tissue at 1 h postdose, although drug levels quickly equilibrated afterwards between lesion and nonlesion areas. A prominent antifungal effect in the infected lung tissue was revealed by histopathological analysis. Isavuconazole also penetrated into the brain with high efficiency. These data further support the value of isavuconazole to treat patients with invasive aspergillosis.
Hygromorphic response dynamics of oak: towards accelerated material characterization (2017)

When a wood board is exposed to a change in relative humidity on only one of its surfaces, e.g. in case of flooring or a panel painting, the resulting asymmetric moisture content profile induces differential expansion over the thickness. Consequently a bending moment causes the board to curve. A theory is presented to describe the bending of a wood board due to a step change in relative humidity. The board is assumed to be homogeneous, isotropic, and linearly elastic. Moisture transport is presumed to obey the diffusion equation with constant coefficients, such that moisture transport can be directly related to the bending of the board. It is shown that the transient deflective behavior provides the diffusion coefficient and the final length change yields the linear hygroscopic expansion coefficient. Derived diffusion coefficients are in good agreement with values in literature. Furthermore, a scaling law for the deflection of the board is proposed, which is seen to be followed qualitatively but not quantitatively by experiments. Finally, by assuming the deflection of the board to be the response of a linear system, the deflective frequency response of the board can be predicted from its step response. The results allow upscaling of deflection and expansion, such that behavior of thick boards can be determined from an experiment using a thin board.
Functional Interplay between Type I Collagen and Cell Surface Matrix Metalloproteinase Activity (2001)

Type I collagen stimulation of pro-matrix metalloproteinase (pro-MMP)-2 activation by ovarian cancer cells involves beta(1) integrin receptor clustering; however, the specific cellular and biochemical events that accompany MMP processing are not well characterized. Collagenolysis is not required for stimulation of pro-MMP-2 activation, and denatured collagen does not elicit an MMP-2 activation response. Similarly, DOV13 cells bind to intact collagen utilizing both alpha(2)beta(1) and alpha(3)beta(1) integrins but interact poorly with collagenase-treated or thermally denatured collagen. Antibody-induced clustering of alpha(3)beta(1) strongly promotes activation of pro-MMP-2, whereas alpha(2)beta(1) integrin clustering has only marginal effects. Membrane-type 1 (MT1)-MMP is present on the DOV13 cell surface as both an active 55-kDa TIMP-2-binding species and a stable catalytically inactive 43-kDa form. Integrin clustering stimulates cell surface expression of MT1-MMP and co-localization of the proteinase to aggregated integrin complexes. Furthermore, cell surface proteolysis of the 55-kDa MT1-MMP species occurs in the absence of active MMP-2, suggesting MT1-MMP autolysis. Cellular invasion of type I collagen matrices requires collagenase activity, is blocked by tissue inhibitor of metalloproteinases-2 (TIMP-2) and collagenase-resistant collagen, is unaffected by TIMP-1, and is accompanied by pro-MMP-2 activation. Together, these data indicate that integrin stimulation of MT1-MMP activity is a rate-limiting step for type I collagen invasion and provide a mechanism by which this activity can be down-regulated following collagen clearance.
Fast space vector modulation based on a neurocomputing digital signal processor (2002)

This paper presents a novel approach to the implementation of the space vector modulation (SVM). The proposed technique takes advantage of a modified Kohonen's competitive layer to calculate the on duration of the adjacent switching state vectors. By using this technique: (a) the hardware and software complexity of the system is reduced; (b) the maximum attainable switching frequency and thus the bandwidth of the control system is increased; and (c) the waveform degradation and parasitic harmonics resulting from inaccurate calculations are avoided. The proposed method is compared to the conventional implementations of SVM techniques in terms of hardware/software requirements, switching frequency, computation time, and harmonic spectra. The method is applied to a DSP controlled 3 kVA unit (voltage source inverter) and experimental results verify the validity of theoretical and simulation results.
Temperature stability of Co/Al2O3/Co junctions (2000)

The temperature stability of magnetic tunnel junctions is an important requirement for the fabrication of magnetic memory devices and the integration in the semiconductor process technology. We have investigated the temperature evolution of the tunneling magnetoresistance (TMR) and the structural properties by isochronal annealing experiments up to 750 K. The magnetically hard electrode of the junction consists of an artificial antiferromagnet Co/Cu/Co, the soft electrode of a Co/Fe bilayer. The tunnel barriers are formed by plasma oxidized Al. The tunnel junctions have TMR signals up to 22% at room temperature. Besides a small increase of the TMR signal after annealing up to 480 K, a first decrease at 530 K and a breakdown beyond 600 K are found. This behavior can be attributed to structural changes of the junctions. Auger depth profiles show an unaltered Al2O3 barrier up to 600 K, but the beginning of interdiffusion processes within the magnetic electrodes already at 540 K and above.
Complex dielectric permittivity extraction based on multilayer thin film microstrip lines (2017)

This study presents an analytical method for the extraction of the complex relative permittivity of multi‐layered dielectric substrates that are used to construct thin film microstrip lines (TFMLs). The proposed approach is based on the analysis of an equivalent parallel plate waveguide filled with a dielectric material whose relative dielectric permittivity is the effective dielectric permittivity of the corresponding TFML. The extraction technique relies only on the knowledge of the complex propagation constant obtained from S ‐parameter measurements and is applicable to a wide range of line dimensions and dielectric permittivity values. For experimental verification, several TFMLs were fabricated, and from the measured scattering parameters, the complex dielectric characteristics of each device are extracted. The extracted relative permittivity and loss tangent values are then compared with the dielectric parameters obtained from a numerical technique based on full wave analyses. The accuracy of the proposed analytical method is shown to be approximately 15 and 5% for the fabricated TFMLs with ratios of the microstrip line width ( W ) to dielectric thickness ( H ), ( W / H ) of 4 and 80, respectively.
Alterations to chromatin in intestinal macrophages link IL‐10 deficiency to inappropriate inflammatory responses (2016)

Intestinal macrophages (IMs) are uniquely programmed to tolerate exposure to bacteria without mounting potent inflammatory responses. The cytokine IL-10 maintains the macrophage anti-inflammatory response such that loss of IL-10 results in chronic intestinal inflammation. To investigate how IL-10-deficiency alters IM programming and bacterial tolerance, we studied changes in chromatin accessibility in response to bacteria in macrophages from two distinct niches, the intestine and bone-marrow, from both wild-type and IL-10-deficient (Il10(-/-) ) mice. We identified chromatin accessibility changes associated with bacterial exposure and IL-10 deficiency in both bone marrow derived macrophages and IMs. Surprisingly, Il10(-/-) IMs adopted chromatin and gene expression patterns characteristic of an inflammatory response, even in the absence of bacteria. Further, when recombinant IL-10 was added to Il10(-/-) cells, it could not revert the chromatin landscape to a normal state. Our results demonstrate that IL-10 deficiency results in stable chromatin alterations in macrophages, even in the absence of bacteria. This supports a model in which IL-10-deficiency leads to chromatin alterations that contribute to a loss of IM tolerance to bacteria, which is a primary initiating event in chronic intestinal inflammation.
Moment Generating Functions of Generalized Wireless Fading Channels and\n Applications in Wireless Communication Theory (2016)

In this paper, new exact and approximate moment generating functions (MGF)\nexpression for generalized fading models are derived. Specifically, we consider\nthe ${\\eta}-{\\lambda}-{\\mu}$, ${\\alpha}-{\\mu}$, ${\\alpha}-{\\eta}-{\\mu}$,\n${\\alpha}-{\\lambda}-{\\mu}$, ${\\alpha}-{\\kappa}-{\\mu}$, and\n${\\alpha}-{\\lambda}-{\\eta}-{\\mu}$ generalized fading distributions to derive\napproximate MGF expressions. The new expressions are very accurate and, in\ncontrast to earlier results in the literature, avoid any complicated special\nfunctions, e.g. the Meijer-$G$ and Fox $H$-functions. As such, the new MGF\nexpressions allow easier and more efficient analytical manipulations, which\nalso apply for their special cases such as the Rayleigh, Rice, and Nakagami-m\nfading. As an illustrative application, the average bit error rates for each of\nthe fading models are evaluated using the new derived MGF expressions. The\naccuracy of the analytical results by using the numerically computed results as\na basis of comparison as well as published results from the literature.\n

An Efficient Evolutionary Task Scheduling/Binding Framework for Reconfigurable Systems (2016)

Several embedded application domains for reconfigurable systems tend to combine frequent changes with high performance demands of their workloads such as image processing, wearable computing, and network processors. Time multiplexing of reconfigurable hardware resources raises a number of new issues, ranging from run-time systems to complex programming models that usually form a reconfigurable operating system (ROS). In this paper, an efficient ROS framework that aids the designer from the early design stages all the way to the actual hardware implementation is proposed and implemented. An efficient reconfigurable platform is implemented along with novel placement/scheduling algorithms. The proposed algorithms tend to reuse hardware tasks to reduce reconfiguration overhead, migrate tasks between software and hardware to efficiently utilize resources, and reduce computation time. A supporting framework for efficient mapping of execution units to task graphs in a run-time reconfigurable system is also designed. The framework utilizes an Island Based Genetic Algorithm flow that optimizes several objectives including performance, area, and power consumption. The proposed Island Based GA framework achieves on average 55.2% improvement over a single-GA implementation and an 80.7% improvement over a baseline random allocation and binding approach.
High performance 70 Gbit/s SPECTS optical-CDMA network testbed (2004)

Error-free operation of an optical code division multiple access (O-CDMA) network testbed with seven simultaneous users at 10 Gbit/s/user distributed in two time slots is demonstrated. The O-CDMA network testbed overcomes the key challenge of multi-user interference by adopting a highly nonlinear fibre-based thresholder and by careful system engineering.
A wireless sensory feedback system for real-time gait modification (2011)

Current rehabilitation technology and techniques have proven effective at modifying and correcting gait abnormalities. They are however limited to laboratory and clinical settings, under the supervision of a specialist. Conventional techniques for quantifying gait asymmetries can be combined with sensory feedback methods to provide an intuitive and inexpensive feedback system for extra-clinical rehabilitation. A wireless feedback system has been designed to collect gait information, process it in real-time, and provide corrective feedback to the user. The corrective feedback can be presented through visual, audible, or vibrotactile methods, or a combination thereof. Initial results have led to improvement in the sensory interface of the device to maximize the corrective influence on inexperienced subjects. These preliminary findings suggest that the wireless feedback device can influence the gait of the user, and effectively adapt to their personal feedback preferences.
Accurate LPI Radar Waveform Recognition With CWD-TFA for Deep Convolutional Network (2021)

Automotive radars, with a widespread emergence in the last decade, have faced various jamming attacks. Utilizing low probability of intercept (LPI) radar waveforms, as one of the essential solutions, demands an accurate waveform recognizer at the intercept receiver. Numerous conventional approaches have been studied for LPI radar waveform recognition, but their performance is inadequate under channel condition deterioration. In this letter, by exploiting deep learning (DL) to capture intrinsic radio characteristics, we propose a convolutional neural network (CNN), namely LPI-Net, for automatic radar waveform recognition. In particular, radar signals are first analyzed by a time-frequency analysis using the Choi-Williams distribution. Subsequently, LPI-Net, primarily consisting of three sophisticated modules, is built to learn the representational features of time-frequency images, in which each module is constructed with a preceding maps collection to gain feature diversity and a skip-connection to maintain informative identity. Simulation results show that LPI-Net achieves the 13-waveform recognition accuracy of over 98% at 0 dB SNR and further performs better than other deep models.
Modified Experiments on the Dynamical Behaviors of the Vibrating Grinding Wheel (1975)

Some dynamical behaviors of the vibrating grinding wheel are experimentally clarified using the wheel model. The model is made of plaster, and consisted of 30φ spherical grains and 8φ×12 cylindrical bonds. The size of the model is 72×114×125. This model is vibrated at the frequency f=50 Hz, and the amplitude a=0.8 1. 5 mm in the active load direction, and is loaded with the impulsive force or the tensile force. The breakdown force of the model and the strains of the bonds are measured. The breakdown appearance is observed by the high speed photograph. From the experiments the following conclusions are obtained.(1) The breakdown time of the model by the impulsive load decreases as the amplitude increases.(2) The tensile breakdown force decreases as the stress amplitude increases, when the tensile force and the vibration stress are loaded simultaneously.(3) The lattice model breaks down to many random pieces for a=0. When that model is vibrating, however, only the bonds of its lowest layer with the maximum vibration stress break down.(4) In the actual vibrating wheel, the mean value of the breakdown force is obtained by measuring the dressing force owing to the insensitive effect of the wheel-dresser vibration system.Therefore, it is considered that the decrease of the dressing force is caused by the decreases of the breakdown time and the breakdown force.
Safety and efficacy of Levucell® SB (Saccharomyces cerevisiae CNCM I‐1079) as a feed additive for all pigs (2019)

Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of Levucell<sup>®</sup> SB when used in feed for suckling piglets, pigs for fattening and minor porcine species. Levucell<sup>®</sup> SB is the trade name for a feed additive based on viable cells of a strain <i>Saccharomyces cerevisiae</i> currently authorised as a zootechnical additive for weaned piglets, sows, chickens for fattening and minor poultry species for fattening. The applicant is now seeking authorisation as a zootechnical additive for use with all pigs. In the context of a previous opinion, the identity of the strain was confirmed, and according to the Qualified Presumption of Safety (QPS) approach to safety assessment, it was presumed safe for the target species, consumers of products from animals fed the additive and the environment. Since no concerns are expected from other components of the additive, Levucell<sup>®</sup> SB is also considered safe for the target species, including all pigs, consumers and the environment. Levucell<sup>®</sup> is not a skin or eye irritant or a skin sensitiser. Inhalation exposure is unlikely. Encapsulation used in the existing coated forms is not expected to introduce hazards for users. In previous opinions, Levucell<sup>®</sup> SB was found to have the potential to be efficacious in sows and weaned piglets at the dose of 1 × 10<sup>9</sup> colony forming units (CFU)/kg complete feedingstuffs. Since the dose proposed for use with all pigs is the same as that demonstrated to be effective in weaned piglets and sows, and it can be reasonably assumed that the mode of action is the same, the conclusion on efficacy for weaned piglets and sows can be extrapolated to all pigs. Therefore, the FEEDAP Panel concludes that Levucell<sup>®</sup> SB has the potential to be efficacious in all pigs at 1 × 10<sup>9</sup> CFU/kg feedingstuffs.
