High Accuracy NURBS Interpolation for Five-axis Machine of Table-rotating/Spindle-tilting Type (2007)

In this paper, the definition of NURBS curve and a speed-controlled interpolation in which the feed rate is automatically adjusted in order to meet the specified chord error limit were discussed. Besides those, a definition of linear interpolation error of post-processed data was proposed, which should be paid more attention to because it will not only reduce quality of the surface but also may cause interference and other unexpected trouble. In order to control the error, a robust algorithm was proposed, which successfully met a desired error limit through interpolating some essential CL data. The excellence of the proposed algorithm, in terms of its reliability and self-adaptiveness, has been proved by simulation results.
Giant tunneling magnetoresistance up to 410% at room temperature in fully epitaxial Co∕MgO∕Co magnetic tunnel junctions with bcc Co(001) electrodes (2006)

Fully epitaxial Co(001)∕MgO(001)∕Co(001) magnetic tunnel junctions (MTJs) with metastable bcc Co(001) electrodes were fabricated with molecular beam epitaxy. The MTJs exhibited giant magnetoresistance (MR) ratios up to 410% at room temperature, the highest value reported to date. Temperature dependence of the MR ratio was observed to be very small compared with fully epitaxial Fe∕MgO∕Fe and textured CoFeB∕MgO∕CoFeB MTJs. The MR ratio of the Co∕MgO∕Co MTJ showed larger bias voltage dependence than that of the epitaxial Fe∕MgO∕Fe MTJs, which probably reflects the band structures of bcc Co and Fe for the k‖=0 direction.
Ability of the CRF Immunoreactive Neurons of the Paraventricular Nucleus to Produce a Vasopressin-Like Material (1983)

In the paraventricular nucleus of normal or adrenalectomized colchicine-treated guinea pigs and rats, corticotropin-releasing factor (CRF), vasopressin (VP) and oxytocin (OX) immunoreactivities were compared. In the control animals, respective stainings for these three peptides are distinct. Adrenalectomy resulted in the appearance of a VP-like staining in most of the CRF-immunoreactive neurons whereas OX staining remained distinct. It is suggested that the CRF/VP coexistence reflects the synergistic role of the two peptides.

Analysis and simulation of low light level image sensors (2006)

A multitude of scientific, medical, and defense applications require imaging at low light level. Examples include: live-cell fluorescence microscopy, wavefront sensing for adaptive optics, and night vision. To address these applications low light level sensors need to have low noise, high quantum efficiency, low lag, high MTF, high frame rates, and low power. Over the past 50 years a variety of techniques have been developed to analyze and compare these technologies. The purpose of this paper is to develop an analytical method for estimating limiting resolution of low light level sensors and cameras. We present a communication theory based model that is designed to enable rapid evaluation of low light level sensors and aid in the understanding of how these systems operate. This model can be applied to electron multiplied CCDs, electron bombarded CMOS sensors, and hybrid CCD/CMOS sensors. In addition we also describe a device physics based low light level camera simulator. We compare our model to the camera simulator and show that the model can be used to accurately predict camera performance. In addition the computational complexity of our model is 1/150 of a complete low light level camera simulator.

Electrochemical Characterization of Mixed Self-Assembled Films of Water-Soluble Single-Walled Carbon Nanotube-Poly(m-aminobenzene sulfonic acid) and Iron(II) Tetrasulfophthalocyanine (2010)

The redox activities of water-soluble iron(II) tetrasulfophthalocyanine (FeTSPc) and single-walled carbon nanotube- poly(-aminobenzene sulfonic acid) (SWCNT-PABS) adsorbed on a gold surface precoated with a self-assembled monolayer (SAM) of 2-dimethylaminoethanethiol (DMAET) have been described. Atomic force microscopy, cyclic voltammetry, and electrochemical impedance spectroscopy were employed to probe the buildup and formation of their thin solid films on the gold surface. The solid films exhibited excellent electrochemical stability. The electrode based on the mixed hybrids (Au-DMAET-SWCNT-PABS/FeTSPc) exhibited the fastest electron transport compared to other electrodes , suggesting the ability of the SWCNT-PABS to act as efficient conducting species that facilitate electron transport between the integrated FeTSPc and the underlying gold substrate. Given the paucity of literature in the SAMs of water-soluble phthalocyanine complexes, the proposed fabrication strategy could potentially be extended to other water-soluble metallophthalocyanines and related organometallic complexes.

Analysis of Transient Currents During Ultrafast Switching of $\hbox{TiO}_{2}$ Nanocrossbar Devices (2011)

In this letter, bipolar fast-pulse switching in TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> -based nanocrossbar devices was investigated. A dedicated measurement setup was used to measure the transient currents during 5-ns resistive switching. Transient peak currents for the set and reset processes were as high as 200 and 230 μA, respectively. The currents observed during fast-pulse switching are explained and simulated by Joule heating, which is needed for fast oxygen-vacancy movement. The measured transient currents enable a further optimization of resistive switches based on TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> .
Optimized universal color palette design for error diffusion (1995)

Currently, many low-cost computers can only simultaneously display a palette of 256 colors. However, this palette is usually selectable from a very large gamut of available colors. For many applications, this limited palette size imposes a significant constraint on the achievable image quality. We propose a method for designing an optimized universal color palette for use with halftoning methods such as error diffusion. The advantage of a universal color palette is that it is fixed and therefore allows multiple images to be displayed simultaneously. To design the palette, we employ a new vector quantization method known as sequential scalar quantization (SSQ) to allocate the colors in a visually uniform color space. The SSQ method achieves near-optimal allocation, but may be efficiently implemented using a series of lookup tables. When used with error diffusion, SSQ adds little computational overhead and may be used to minimize the visual error in an opponent color coordinate system. We compare the performance of the optimized algorithm to standard error diffusion by evaluating a visually weighted mean-squared-error measure. Our metric is based on the color difference in CIE L *a *b , but also accounts for the lowpass characteristic of human contrast sensitivity.
Scalable user selection in FDD massive MIMO (2021)

Abstract User subset selection requires full downlink channel state information to realize effective multi-user beamforming in frequency-division duplexing (FDD) massive multi-input multi-output (MIMO) systems. However, the channel estimation overhead scales with the number of users in FDD systems. In this paper, we propose a novel propagation domain-based user selection scheme, labeled as zero-measurement selection , for FDD massive MIMO systems with the aim of reducing the channel estimation overhead that scales with the number of users. The key idea is to infer downlink user channel norm and inter-user channel correlation from uplink channel in the propagation domain. In zero-measurement selection, the base-station performs downlink user selection before any downlink channel estimation. As a result, the downlink channel estimation overhead for both user selection and beamforming is independent of the total number of users. Then, we evaluate zero-measurement selection with both measured and simulated channels. The results show that zero-measurement selection achieves up to 92.5% weighted sum rate of genie-aided user selection on the average and scales well with both the number of base-station antennas and the number of users. We also employ simulated channels for further performance validation, and the numerical results yield similar observations as the experimental findings.
Characterizing Thermal Mixing Dynamic Nuclear Polarization via Cross-Talk between Spin Reservoirs (2017)

Dynamic nuclear polarization (DNP) embraces a family of methods to increase signal intensities in nuclear magnetic resonance (NMR) spectroscopy. Despite extensive theoretical work that allows one to distinguish at least five distinct mechanisms, it remains challenging to determine the relative weights of the processes that are responsible for DNP in state-of-the-art experiments operating with stable organic radicals like nitroxides at high magnetic fields and low temperatures. Specifically, determining experimental conditions where DNP involves thermal mixing, which denotes a spontaneous heat exchange between different spin reservoirs, remains challenging. We propose an experimental approach to ascertain the prevalence of the thermal mixing regime by monitoring characteristic signature properties of the time evolution of the hyperpolarization. We find that thermal mixing is the dominant DNP mechanism at high nitroxide radical concentrations, while a mixture of different mechanisms prevails at lower concentrations.
Formation of an NIR-emitting Ag34S3SBB20(CF3COO)62+ cluster from a hydride-protected silver cluster (2019)

Recent reports have shown that the intercluster reaction is a new synthetic strategy to prepare alloy clusters. In this work, we performed an intercluster reaction between silver clusters and produced highly ionizable Ag-S-type clusters; we examined their formation by mass spectrometry. [Ag<sub>18</sub>(TPP)<sub>10</sub>H<sub>16</sub>]<sup>2+</sup> (Ag<sub>18</sub>), a highly reactive hydride and phosphine-protected silver cluster, was used as a sacrificial cluster in this synthesis. An intercluster reaction between Ag<sub>18</sub> and smaller silver-chalcogenolate clusters (SCC) resulted in a new cluster, [Ag<sub>34</sub>S<sub>3</sub>SBB<sub>20</sub>(CF<sub>3</sub>COO)<sub>6</sub>]<sup>2+</sup>. The cluster showed an NIR emission at around 1100 nm. The cluster composition was confirmed by high-resolution electrospray ionization mass spectrometry (ESI-MS), thermogravimetry (TGA), and X-ray photoelectron spectroscopy (XPS).

High-speed hyperspectral imaging enabled by compressed sensing in time domain (2023)

Hyperspectral imaging (HSI) is a powerful tool widely used for various scientific and industrial applications due to its ability to provide rich spatiospectral information. However, in exchange for multiplex spectral information, its image acquisition rate is lower than that of conventional imaging, with up to a few colors. In particular, HSI in the infrared region and using nonlinear optical processes is impractically slow because the three-dimensional (3D) data cube must be scanned in a point-by-point manner. In this study, we demonstrate a framework to improve the spectral image acquisition rate of HSI by integrating time-domain HSI and compressed sensing. Specifically, we simulated broadband coherent Raman imaging at a record high frame rate of 25 frames per second (fps) with 100 pixels × 100 pixels, which is 10 × faster than that of previous work, based on an experimentally feasible sampling scheme utilizing 3D Lissajous scanning.
Implementing a dynamic processor allocation policy for multiprogrammed parallel applications in the SolarisTM (2001)

Abstract Parallel applications typically do not perform well in a multiprogrammed environment that uses time‐sharing to allocate processor resources to the applications' parallel threads. Co‐scheduling related parallel threads, or statically partitioning the system, often can reduce the applications' execution times, but at the expense of reducing the overall system utilization. To address this problem, there has been increasing interest in dynamically allocating processors to applications based on their resource demands and the dynamically varying system load. The Loop‐Level Process Control (LLPC) policy (Yue K, Lilja D. Efficient execution of parallel applications in multiprogrammed multiprocessor systems. 10th International Parallel Processing Symposium , 1996; 448–456) dynamically adjusts the number of threads an application is allowed to execute based on the application's available parallelism and the overall system load. This study demonstrates the feasibility of incorporating the LLPC strategy into an existing commercial operating system and parallelizing compiler and provides further evidence of the performance improvement that is possible using this dynamic allocation strategy. In this implementation, applications are automatically parallelized and enhanced with the appropriate LLPC hooks so that each application interacts with the modified version of the Solaris operating system. The parallelism of the applications are then dynamically adjusted automatically when they are executed in a multiprogrammed environment so that all applications obtain a fair share of the total processing resources.

Nature and biosynthesis of galacto-oligosaccharides related to oligosaccharides in human breast milk (2014)

Human milk oligosaccharides (HMO) are prominent among the functional components of human breast milk. While HMO have potential applications in both infants and adults, this potential is limited by the difficulties in manufacturing these complex structures. Consequently, functional alternatives such as galacto-oligosaccharides are under investigation, and nowadays, infant formulae are supplemented with galacto-oligosaccharides to mimic the biological effects of HMO. Recently, approaches toward the production of defined human milk oligosaccharide structures using microbial, fermentative methods employing single, appropriately engineered microorganisms were introduced. Furthermore, galactose-containing hetero-oligosaccharides have attracted an increasing amount of attention because they are structurally more closely related to HMO. The synthesis of these novel oligosaccharides, which resemble the core of HMO, is of great interest for applications in the food industry.
Anatomical study of the female reproductive system and bacteriome of Diaphorina citri Kuwayama, (Insecta: Hemiptera, Liviidae) using micro-computed tomography (2020)

Huanglongbing (HLB) (citrus greening disease) is one of the most serious bacterial diseases of citrus. It is caused by (1) Candidatus Liberibacter africanus, transmitted by Trioza erytreae and (2) C.L. asiaticus and C.L. americanus, transmitted by Diaphorina citri. As part of a multidisciplinary project on D. citri (www.citrusgreening.org), we made a detailed study, using micro-computed tomography, of the female abdominal terminalia, reproductive system (ovaries, accessory glands, spermatheca, colleterial (= cement) gland, connecting ducts, and ovipositor) and bacteriome, which we present here. New terms and structures are introduced and described, particularly concerning the spermatheca, ovipositor and bacteriome. The quality of images and bacteriome reconstructions are comparable, or clearer, than those previously published using a synchrotron or fluorescence in situ hybridisation (FISH). This study: reviews knowledge of the female reproductive system and bacteriome organ in D. citri; represents the first detailed morphological study of D. citri to use micro-CT; and extensively revises existing morphological information relevant to psylloids, hemipterans and insects in general. High quality images and supplementary videos represent a significant advance in knowledge of psylloid anatomy and are useful tools for future research and as educational aids.

Effects of Tandem Pulse on Stone Comminution in an Electromagnetic Shock Wave Lithotripter (2007)

Despite recent innovations in lithotripter design and technology, the first generation Dornier HM-3 electrohydraulic lithotripter remains the most effective clinical, non-invasive modality for comminuting stones. Understanding the fundamental differences between the HM-3 and more clinically practicable lithotripters is critical to achieving meaningful improvements in future models. This study aims to further clarify the role of the second, weaker pulse of the HM-3 in stone comminution by introducing a similar pulse in the pressure profile of an electromagnetic lithotripter. Additionally, this study investigates the potential for this tandem shock technique to improve comminution in electromagnetic lithotripters through optimization of the interpulse delay time.

High-speed asynchronous data multiplexing/demultiplexing (1999)

High-speed data acquisition and communication systems require fast multiplexing and demultiplexing of data. We are developing novel multiplexer/demultiplexer circuits using a dual-rail approach. A single cell of the demultiplexer is a toggle type B flip-flop. The demultiplexer operates at 95 GHz and its performance does not depend on the demultiplexing ratio. The dual-rail technique avoids racing between data and clock signals. The multiplexer circuit is based on RS type B flip-flops and works up to 60 GHz. The circuits are implemented in HYPRES' standard Nb process with a critical current density of 1.0 KA/cm/sup 2/.
Temperature Dependent Luminescence of Yellow‐Emitting α‐Sialon:Eu 2+ Oxynitride Phosphors for White Light‐Emitting Diodes (2009)

Yellow‐emitting α‐sialon:Eu 2+ phosphors have been reported as interesting down‐conversion luminescent materials in white LEDs. In this work, the thermal quenching of α‐sialon:Eu 2+ with the compositions of M val+ ( m /val+) Si 12−( m + n ) Al m + n O n N 16− n (M=Ca, Mg, Lu) is studied by investigating the effects of chemical composition, activator concentration, and substitution cation on the temperature‐dependent luminescence. The chemical composition of α‐sialon:Eu 2+ was varied in a wide range (0.5≤ m ≤2.0, 1≤ n ≤1.8). It shows that the m value significantly affects the thermal quenching of α‐sialon, whereas the n value hardly does. This difference is ascribed to the obvious lattice expansion and the increase of absolute activator concentration as m increases. The thermal quenching increases with increasing the Eu 2+ concentration, which is due to enhanced Stokes shift. The type of substitution cation also has an influence on thermal quenching. Among the substitution cations in this work, Lu‐α‐sialon:Eu 2+ exhibits largest thermal quenching. Photoionization is considered as the mechanism for the thermal quenching of Lu‐α‐sialon: Eu 2+ .
Automatic Adaptation of Person Association for Multiview Tracking in Group Activities (2018)

Reliable markerless motion tracking of people participating a complex group activity from multiple moving cameras is challenging due to frequent occlusions, strong viewpoint and appearance variations, and asynchronous video streams. To solve this problem, reliable association of the same person across distant viewpoints and temporal instances is essential. We present a self-supervised framework to adapt a generic person appearance descriptor to the unlabeled videos by exploiting motion tracking, mutual exclusion constraints, and multi-view geometry. The adapted discriminative descriptor is used a tracking-by-clustering formulation. We validate the effectiveness of our descriptor learning on WILDTRACK [14] and three new complex social scenes captured by multiple cameras with up to 60 people in the wild. We report significant improvement association accuracy (up to 18%) and stable and coherent 3D human skeleton tracking (5 to 10 times) over the baseline. Using the reconstructed 3D skeletons, we cut the input videos into a multi-angle video where the image of a specified person is shown from the best visible front-facing camera. Our algorithm detects inter-human occlusion to determine the camera switching moment while still maintaining the flow of the action well.

Evaluation of the importance of mechatronical concepts in practical applications (2013)

Mechatronical engineering is a strong trend within engineering of manufacturing systems. To enable a most efficient and beneficiary application of mechatronical engineering within engineering organizations the mechatronical engineering has to be based on basic concepts realizing the mechatronical thinking and supporting the user. Even though such concepts have been identified they might be of different interest depending on application cases, industry focus, engineering phases, and much more. Within this paper the results of an expert survey will be given enabling the estimation of the practical impact of mechatronical concepts and the believes of practitioners about the moment of availability of such concepts in engineering tools or tool chains.
Event Timeline Generation from History Textbooks. (2017)

Event timeline serves as the basic structure of history, and it is used as a disposition of key phenomena in studying history as a subject in secondary school. In order to enable a student to understand a historical phenomenon as a series of connected events, we present a system for automatic event timeline generation from history textbooks. Additionally, we propose Message Sequence Chart (MSC) and time-map based visualization techniques to visualize an event timeline. We also identify key computational challenges in developing natural language processing based applications for history textbooks.
