A Scoping Review on the Therapeutic Potential of Resin From the Species Larix decidua Mill. [Pinaceae] to Treat Ulcerating Wounds (2022)

Malignant ulcerating wounds or neoplastic lesions are a considerable burden for patients suffering from advanced cancer. These wounds have no effective treatment and are very difficult to manage. The present review summarizes evidence in support of a hypothesis put forward in anthroposophic medicine, which suggests a beneficial role of resin from the species <i>Larix decidua</i> Mill. [Pinaceae] for treating such wounds. A systematic search strategy was performed using the databases PubMed, EMBASE and SciFinder. The included publications described the chemical composition of this species, as well as <i>in vitro</i>, <i>in vivo</i>, and <i>ex vivo</i> experiments using plant extracts and isolated compounds. The results show that among the phytochemical classes, terpenoids were the major components of this species, especially in the resin. The summarized biological experiments revealed antimicrobial, antioxidant and anti-inflammatory effects, with promising potential for the extracts and isolated compounds. However, the molecular mechanisms and toxicological effects are as of yet not conclusively evaluated. From the data of our study, we can conclude that <i>L. decidua</i> might indeed have a promising potential for the treatment of malignant wounds, but definitive information that can prove its effectiveness is still lacking. We therefore suggest that future efforts should be dedicated to the evaluation of <i>L. decidua</i> resin's therapeutic use considering its antiseptic action and proposed wound healing properties.
HACS: Human Action Clips and Segments Dataset for Recognition and Temporal Localization (2017)

This paper presents a new large-scale dataset for recognition and temporal localization of human actions collected from Web videos. We refer to it as HACS (Human Action Clips and Segments). We leverage both consensus and disagreement among visual classifiers to automatically mine candidate short clips from unlabeled videos, which are subsequently validated by human annotators. The resulting dataset is dubbed HACS Clips. Through a separate process we also collect annotations defining action segment boundaries. This resulting dataset is called HACS Segments. Overall, HACS Clips consists of 1.5M annotated clips sampled from 504K untrimmed videos, and HACS Seg-ments contains 139K action segments densely annotatedin 50K untrimmed videos spanning 200 action categories. HACS Clips contains more labeled examples than any existing video benchmark. This renders our dataset both a large scale action recognition benchmark and an excellent source for spatiotemporal feature learning. In our transferlearning experiments on three target datasets, HACS Clips outperforms Kinetics-600, Moments-In-Time and Sports1Mas a pretraining source. On HACS Segments, we evaluate state-of-the-art methods of action proposal generation and action localization, and highlight the new challenges posed by our dense temporal annotations.
COMBINATION OF FUZZY ARITHMETIC AND A FAST BOUNDARY ELEMENT METHOD FOR ACOUSTIC SIMULATION WITH UNCERTAINTIES (2009)

A so-called FuzzBEM methodology for analyzing the influence of uncertain acoustic and structural parameters on the radiated sound field of vibrating structures combining fuzzy arithmetic and fast multipole boundary element method is introduced. Uncertainties in acoustic properties may result from uncertain parameters of the vibrating mechanical structures, e.g. material density or geometry, as well as from uncertainties in the acoustic domain, e.g. sound velocity. The use of the transformation method in the proposed approach allows to employ simulation tools based on the crisp number arithmetic by appropriate preprocessing of the fuzzy numbers modeling the uncertain input parameters and postprocessing of the simulation results to determine the fuzzy numbers for the considered output quantities. In this contribution, the proposed FuzzBEM procedure is applied to a sound radiating, vibrating stiffened cylindrical shell where the investigated uncertainties include the shell wall thickness and the driving frequency of a monofrequency point load and the air density and sound velocity. As exemplary output quantities of acoustic performance, the acoustic pressure at multiple field points and the radiated sound power are evaluated. The proposed coupling of fuzzy arithmetic and acoustic boundary elements yields run times two orders of magnitudes or more longer than a single BEM calculation. Nevertheless, the systematic parameterization obtained by the proposed fuzzy analysis has the potential to reveal input–output relationships difficult to identify with individual conventional BEM simulation runs.
Surface Profile Measurements with a Portable Thin Plate Type Sensor Composed of a Piezoelectric Polymer (2016)

For the quality-check process of manufacturing, skilled workers often use their sense of touch for inspections. However, this method is non-quantitative and depends on the experience of the workers. Therefore, a measurement device that can acquire quantitative surface profile data more easily than existing equipment is required. In our previous study, we prototyped a cantilever structured thin plate tactile sensor, with an attached piezoelectric polymer film as a strain detector, and showed that this sensor can evaluate uneven surface profiles. However, these measurements were performed by moving the tactile sensor with an automatic linear stage. To make the measurement tasks at an actual work site easier, an operator must be able to choose any target surface and evaluate that surface without troublesome settings and jigs. Therefore, in this study, we prototyped a portable, manually operated tactile sensor system comprising two thin plate tactile sensors. We showed that this prototype sensor system can estimate the amount of sensor movement during measurements by calculating the time lag between two sensor signals. Using the estimated amount of movement, this sensor system can evaluate uneven surface profiles easily and quickly.

Efficient Hardware Architectures for 1D- and MD-LSTM Networks (2020)

Abstract Recurrent Neural Networks, in particular One-dimensional and Multidimensional Long Short-Term Memory (1D-LSTM and MD-LSTM) have achieved state-of-the-art classification accuracy in many applications such as machine translation, image caption generation, handwritten text recognition, medical imaging and many more. However, high classification accuracy comes at high compute, storage, and memory bandwidth requirements, which make their deployment challenging, especially for energy-constrained platforms such as portable devices. In comparison to CNNs, not so many investigations exist on efficient hardware implementations for 1D-LSTM especially under energy constraints, and there is no research publication on hardware architecture for MD-LSTM. In this article, we present two novel architectures for LSTM inference: a hardware architecture for MD-LSTM, and a DRAM-based Processing-in-Memory (DRAM-PIM) hardware architecture for 1D-LSTM. We present for the first time a hardware architecture for MD-LSTM, and show a trade-off analysis for accuracy and hardware cost for various precisions. We implement the new architecture as an FPGA-based accelerator that outperforms NVIDIA K80 GPU implementation in terms of runtime by up to 84× and energy efficiency by up to 1238× for a challenging dataset for historical document image binarization from DIBCO 2017 contest, and a well known MNIST dataset for handwritten digits recognition. Our accelerator demonstrates highest accuracy and comparable throughput in comparison to state-of-the-art FPGA-based implementations of multilayer perceptron for MNIST dataset. Furthermore, we present a new DRAM-PIM architecture for 1D-LSTM targeting energy efficient compute platforms such as portable devices. The DRAM-PIM architecture integrates the computation units in a close proximity to the DRAM cells in order to maximize the data parallelism and energy efficiency. The proposed DRAM-PIM design is 16.19 × more energy efficient as compared to FPGA implementation. The total chip area overhead of this design is 18 % compared to a commodity 8 Gb DRAM chip. Our experiments show that the DRAM-PIM implementation delivers a throughput of 1309.16 GOp/s for an optical character recognition application.
Tunable Fiber Bragg Grating Combined with Microactuator (2002)

A tunable fiber Bragg grating combined with a microactuator is described. The electromagnetically driven microactuator realizes the mechanism for twisting the fiber, and the strain is generated inside the fiber Bragg grating. The twisting-type microactuator is prepared by bulk Si micromachining, and the optical fiber is thinned down to 30 µm diameter at the Bragg grating region for reducing the torsional rigidity of the fiber and for confining the strain. The strain changes the refractive index of the optical fiber due to the photoelastic effect. The twisting angle of the fiber reaches over 6 deg and the redshift of the Bragg wavelength up to 0.25 nm is demonstrated.
Biological Study Using 3-D Tissue Cytometry (2009)

3-D tissue cytometry has been successfully developed to optimize biological specimen throughput allowing the characterization of cell-cell, cell-tissue interaction to be quantified in 3-D tissue by combining high speed TPM, automated x-y specimen stage, and precision specimen sectioning mechanism. 3-D tissue cytometry is applied in two biomedical applications.
Relationships between the molecular architecture, crystallization capacity, and miscibility in poly(butylene terephthalate)/polycarbonate blends: A comparison with poly(ethylene terephthalate)/polycarbonate blends (2004)

Abstract Poly(butylene terephthalate) (PBT)/polycarbonate (PC) samples, prepared via reactive blending in the presence of Ti‐ and Sm‐based catalysts, resulted in block copolymers whose block length decreased as the mixing time increased. A single homogeneous amorphous phase occurred when the blocks had monomeric sequences shorter than 10 units. Otherwise, a crystalline phase of PBT developed. Also, in poly(ethylene terephthalate) (PET)/PC blends previously studied, the miscibility was strictly correlated with the crystallizability of the system. Therefore, the miscibility of the PBT/PC and PET/PC blends was compared with respect to the tendency of the PBT and PET blocks to crystallize under isothermal conditions. The crystallization rate of the PBT/PC copolymers was faster than that of the PET/PC copolymers with similar block lengths. Accordingly, the minimum crystallizable sequence length of the PBT blocks was shorter than that of the PET blocks (18 vs 31 monomeric unit sequences). This behavior was interpreted as an effect of the more flexible PBT units, which had a greater tendency to fold and crystallize than the PET units. Therefore, PBT, the blocks of which tended to crystallize even if they were very short and phase‐separated, was characterized by a poorer compatibility with PC than that of PET. As a result, the block size had a fundamental role in determining the crystallizability and, therefore, phase behavior of the semicrystalline block copolymers. © 2004 Wiley Periodicals, Inc.

Constructing Multifunctional Virus-Templated Nanoporous Composites for Thin Film Solar Cells: Contributions of Morphology and Optics to Photocurrent Generation (2015)

Biotemplates, such as the high aspect ratio M13 bacteriophage, can be used to nucleate noble metal nanoparticles and photoactive materials such as metal oxides, as well as organize them into continuous structures. Such attributes make them attractive scaffolds for solar applications requiring precise organization at the nanoscale. For instance, thin film solar cells benefit from nanostructured morphologies that aid light absorption and carrier transport. Here, we present a biotemplating strategy for assembling nanostructured thin film solar cells that enhance the generated photocurrent through two features: (1) a nanoporous and continuous M13 bacteriophage-templated titania network that improves charge collection and (2) the incorporation of metal nanoparticles within the active layer of the device to improve light harvesting. We demonstrate our ability to construct virus-templated solar cells by applying this strategy to depleted titania–lead sulfide quantum dot (PbS QD) bulk heterojunctions. The titania morphology produced by our biotemplate allows charges to be efficiently collected from the bulk of the active material and light that is otherwise poorly absorbed by the QDs to be harvested using metal nanoparticles that exhibit plasmon resonances in the visible range. We show that high aspect ratio bacteriophages provide a structural template for synthesizing titania networks with tunable porosity, into which PbS QDs are infiltrated to create photoactive nanocomposites suitable for photovoltaics. Upon optimization, the generated photocurrent and power conversion efficiency of the bacteriophage-templated devices demonstrate a 2-fold improvement over those of control devices made with randomly organized titania nanoparticles. When the virus is complexed with gold nanoparticles (Au NPs), silver nanoparticles (Ag NPs), or silver nanoplates (Ag NPLs) during assembly, the device performance is further improved, with Ag NPLs enhancing the short-circuit current density and power conversion efficiency by 16% and 36.5%, respectively, over those of virus-based devices without NPs. The observed trends in photocurrent enhancement match well with numerical predictions, and the role of the nanostructured morphology on the device optics was computationally explored. The challenges overcome in this work could be extended to other heterojunction devices, such as hybrid systems involving conducting polymers, as well as other biologically templated electronics.

Hybrid semiconductive/high-temperature superconductive tunable preselector (2002)

HTSC lumped element filters with GaAs varactor tuning, P-HEMT LNAs with HTSC lumped element matching and a GaAs MMIC SP4T switch with integrated decoding are described for use in a broadband cryogenic preselector operating from 200 MHz to 2 GHz. The filters tune over their respective sub-bands and have insertion losses ranging from 2 to 14 dB. The sub-band LNAs have from 8.5 to 11.5 dB of gain, noise figures under 1.5 dB and input return losses greater than 20 dB. The SP4T MMIC multiplexing switch has under 0.5 dB insertion loss, isolation in excess of 30 dB and 10/90% switching speed under 100 nsec. These components are designed to be assembled into a 30 cubic centimeter electronically tunable four-channel proof-of-principal preselector operating over portions of the 200 MHz to 2 GHz band.
Benefits of direct-to tool in National Airspace System (2000)

Initiatives in air traffic management both in the United States and in Europe are aimed at providing air traffic controllers with automation tools to separate traffic, meet time constraints required for traffic flow and accommodate route preferences of users such as airlines. These efforts are expected to result in removal of restrictions on users preferred routes without compromising safety. Thus, aircraft will be able to fly optimal routes such as great circle and wind-optimal routes. NASA has developed the design for a new automation tool, referred to as the direct-to tool, which advises the controller on direct time-saving routes for any aircraft irrespective of levels of equipage. In contrast to earlier studies on the potential benefits of direct routes in the National Airspace System, the objective of the paper is to evaluate the benefits based on a controller tool. The paper describes the benefits of applying this algorithm to the 20 air route traffic control centers within the United States. Benefits are measured in terms of the total time savings accrued by flying the direct route. Results are described for three different implementations dependent on the search region bounding each air route traffic control center. The first region exactly encloses the air route traffic control center airspace, the second is the smallest rectangular bounding region while the third is a bigger rectangular bounding region approximately twice as large as the second region. It is shown that the application of the direct-to routing algorithm does not significantly alter the number of conflicts and their spatial distribution compared to the case in which the aircraft fly along the airways. The results presented in the paper suggest that the direct-to routing algorithm can provide significant cost savings to the users without adversely impacting the air traffic management functions.
Exploring diversity (2008)

As the number of wireless devices increase, the frequency spectrum becomes further congested. Deployments of wireless devices in harsh radio environments (i.e. an industrial plant) also motivates the study of alternate communication protocols that offer enough diversity to overcome interference. This work explores the use of frequency diversity to address this problem and examines its effectiveness in various environmental settings. We also examine the interplay between frequency agility at the MAC layer and route diversity in the network layer and look to understand the cost-tradeoffs in the diversity of choices offered by each layer.
Effect of clavulanic acid on the activity of ticarcillin against Pseudomonas aeruginosa (1986)

We studied the ability of clavulanic acid (CA) to induce beta-lactamase in Pseudomonas aeruginosa isolates and what effect this might have on the susceptibilities to beta-lactam agents. We first used a disk approximation method to test 4 laboratory and 16 clinical P. aeruginosa isolates against antipseudomonal beta-lactam agents for truncation by CA and found this to be very common. All antimicrobial compounds except imipenem demonstrated truncation in the vicinity of CA. We also evaluated the extent to which chromosomal beta-lactamase is induced by CA and found this to occur to some degree in most isolates and to be dependent on the concentration of CA. Finally, we performed time kill curves on these isolates to compare bacterial growth in ticarcillin alone with growth in ticarcillin-CA (the CA at 2 or 4 micrograms/ml). We found that CA at this concentration has neither an antagonistic nor a synergistic antibacterial effect in combination with ticarcillin.
Temperature dependence of free carriers and optical phonons in<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mi>LiInSe</mml:mi><mml:mn>2</mml:mn></mml:msub></mml:math>in the terahertz frequency regime (2015)

We investigate free carriers dynamics and anharmonic decay of optical phonons in ${\mathrm{LiInSe}}_{2}$ by using low temperature THz time-domain spectroscopy. The quantitatively determined refractive index and absorption coefficient are significantly influenced by temperature. By fitting the evaluated dielectric functions with a Drude-Lorentz model, the temperature dependencies of the plasmon frequency, scattering rates of free carriers, activation energies of carriers, and frequencies and linewidths of optical phonons are investigated. The contributions of three- and four-phonon processes to the temperature dependent optical phonon frequency and linewidth variations are quantitatively determined.
Unique waveform characteristics of current limiting fuse operations (2010)

This paper identifies and quantifies the unique characteristics of current-limiting fuse operation as seen in the current and voltage waveforms recorded at a monitoring station located upstream from the fault. Characteristics that can be used to identify current-limiting fuse operations by visual inspection are described. More characteristics are extracted using signal processing methods. These characteristics include but not limited to the duration of the event, point on the waveform where the event starts and ends, the rate of rise of the voltage and current at the start of the event, and the thermal energy in the fuse during the event. These methods are applied to data collected by a number of utilities and the results tabulated. In the future, the results can be used to automatically classify events that are recorded by power quality monitors.
Melatonin binding proteins identified in the rat brain by affinity labeling (1991)

N-Bromoacetyl-2-iodo-5-methoxytryptamine (BIM), a novel derivative of the biologically active melatonin analog, 2-iodomelatonin, was prepared and used to identify melatonin binding proteins in rat brain synaptosomes. Incubation of the synaptosomes with BIM resulted in a time and concentration dependent, irreversible inhibition of 2-[125I]iodomelatonin binding. In parallel, the radioactive form of BIM, N-bromoacetyl-2-[125I]iodo-5-methoxytryptamine ([125I]BIM) became incorporated into the synaptosomes. The incorporation of [125I]BIM was inhibited by BIM, 2-iodomelatonin and melatonin but not by 5-methoxytryptamine or N-acetyl serotonin. [125I]BIM became covalently attached to three polypeptides with apparent molecular weight values of 92, 55 and 45 kDa; the labeling of all three proteins was markedly inhibited by melatonin. These results indicate that the 92, 55 and 45 kDa polypeptides are melatonin binding proteins.
