Performance Analysis of the Multi-GPU System with ExpEther (2014)

A GPU cluster in which each node provides a few GPUs connected with PCIe (PCI Express) is commonly used for acceleration of a large application program requiring the performance beyond a single GPU. However, in such a system, programmers are required to describe two parallel programming between nodes in MPIs or other message passing library as well as the fine grained parallel programming for intra-GPUs. As a cost effective alternative of such clusters, we propose a novel multi-GPU system with ExpEther, a virtualization technique which extends PCIe of a host CPU to Ethernet. All devices connected by ExpEther can be treated as if they were directly connected to the host. Evaluation with two application programs with and without GPU-GPU communication revealed that the proposed system with four GPUs achieved 3.88 and 3.29 times performance improvement respectively compared with a single GPU system. Compared with GPU cluster system in which each node provides a GPU, the proposed system achieved about 7% and 30% performance improvement, respectively.
UHF RFID Voltage Multiplier design from a harmonic communication perspective (2021)

Harmonic communication is an option for enhancing tag to reader communication in UHF RFID systems. In this work different voltage multiplier configurations, diodes, operation scenarios and generated harmonics have been evaluated at simulation level in order to suggest voltage multiplier design guides to increase the available harmonic power. The results show that single side topologies with minimum amount of stages are preferred. Regarding the diode, a proposed modified PMOS diode has shown higher generated harmonic power than Schottky diodes. Regarding the generated harmonics, the second order harmonic is more sensitive to the design parameters. It can be generated with a maximum power of −30 dBm for an input power of −20 dBm. In the case of the third order harmonic, the obtained power is more stable against the design variations and has a maximum value of −34 dBm.
Generation of Multiple Side Lines around Kerr Comb Lines by a Second Pump Coupled into the Soliton Resonance (2018)

We demonstrate the generation of multiple side lines around Kerr comb lines by injecting a second pump into the soliton resonance. The side lines around each comb lines have relatively high power and are stable.
Glass cutting optimization with pump-probe microscopy and Bessel beam profiles (2018)

The processing of transparent materials by ultrashort pulses has opened diverse promising and fast-growing application areas such as the cutting of glasses for consumer electronics. One of the major benefits is the precise energy deposition, which may result in local weakening of the glass and hence defines a preferential direction for the separation path. Due to the vast variety of possible uses for different displays, research in this field is needed for more complex shapes and glasses of various thicknesses. Bessel-Gaussian beams with their elongated, thin focus profile and self-healing nature are an excellent fit, even for glasses up to several millimeters. Additional development to more complex beam profiles allows precise tailoring with respect to the mandatory specifications of the cutting process such as process speed or the realization of inner contours. One concept for the latter is the use of tilted Bessel-Gaussian beams to achieve both high quality and easy separation. Further approaches include the usage of higher-order Bessel beams or modified Gauss-Bessel beams. We employ digital holographic techniques to create the various profiles with the desired absorption distribution. Traditional microscopes fail to characterize these sensible changes in the interaction region, since they are limited to visualize permanent changes (ex situ) of the glass structure only. We take advantage of pump-probe microscopy to receive concise recordings of the extinction mechanisms of the beam-material-interaction. With both, high temporal and spatial resolution of in-situ diagnostics we gain access to the entire process window which enables us to develop optimized processing parameters for high-quality glass cuttings.
Pepper's Cone (2017)

This paper describes a simple 3D display that can be built from a tablet computer and a plastic sheet folded into a cone. This display allows naturally viewing a three-dimensional object from any direction over a 360-degree path of travel without the use of a head mount or special glasses. Inspired by the classic Pepper's Ghost illusion, our approach uses a curved transparent surface to reflect the image displayed on a 2D display. By properly pre-distorting the displayed image our system can produce a perspective-correct image to the viewer that appears to be suspended inside the reflector. We use the gyroscope integrated into modern tablet computers to adjust the rendered image based on the relative orientation of the viewer. The end result is a natural and intuitive interface for inspecting a 3D object. Our choice of a cone reflector is obtained by analyzing optical performance and stereo-compatibility over rotationally-symmetric conic reflector shapes. We also present the prototypes we built and measure the performance of our display through side-by-side comparisons with reference images.

Protection of MV/LV solid-state transformers in the distribution grid (2015)

Solid-State Transformers (SSTs) are a promising technology since they combine a high efficiency with the integration of new functionalities and services in the grid. A SST establishes the interface between a MV AC three-phase grid and a LV AC or DC grid. For this reason a SST is subject to electrical stresses due to faults occurring in the grid. The MV and LV grids are in return exposed to failures of the SSTs. Therefore, a suitable design of the SST and its corresponding protection devices has to be found. This paper identifies the different stresses which are relevant for a SST, analyzes the protection mechanisms which are currently used for low-frequency transformers and proposes adapted protection schemes for SSTs. MV short circuits and overvoltages are identified as the most critical stresses and are analyzed in detail. Finally, some guidelines are extracted for designing a robust SST.
Ultra-compact fiber-optic two-photon microscope for functional fluorescence imaging in vivo (2008)

We present a small, lightweight two-photon fiberscope and demonstrate its suitability for functional imaging in the intact brain. Our device consists of a hollow-core photonic crystal fiber for efficient delivery of near-IR femtosecond laser pulses, a spiral fiber-scanner for resonant beam steering, and a gradient-index lens system for fluorescence excitation, dichroic beam splitting, and signal collection. Fluorescence light is remotely detected using a standard photomultiplier tube. All optical components have 1 mm dimensions and the microscope's headpiece weighs only 0.6 grams. The instrument achieves micrometer resolution at frame rates of typically 25 Hz with a field-of-view of up to 200 microns. We demonstrate functional imaging of calcium signals in Purkinje cell dendrites in the cerebellum of anesthetized rats. The microscope will be easily portable by a rat or mouse and thus should enable functional imaging in freely behaving animals.
The capsid protein of Semliki Forest virus has clusters of basic amino acids and prolines in its amino-terminal region. (1980)

The amino acid sequence of the capsid (C) protein was deduced from the nucleotide sequence of the C gene. This part of the viral 42S RNA genome was transcribed into double-stranded cDNA. The cDNA was cloned in the Escherichia coli chi 1776-pBR322 host-vector system and then the base sequence was determined with the technique described by Maxam and Gilbert. The amino acid sequence of the C protein shows a clustering of basic amino acids and prolines within the first 110 amino acids.
Endogenous stem/progenitor cell recruitment for tissue regeneration (2014)

The utilization of transplanted stem cells in regenerative medicine has been studied extensively as a potential therapy to repair or replace tissues that are lost due to trauma, congenital deformities, tumor resections, or infectious diseases [1–3]. The current cell transplantation model in regenerative medicine is founded on the principle that the application of transplanted stem cells could repopulate and regenerate damaged or diseased tissues, with restored tissue functions and homeostasis. However, cell transplantation is faced with a multitude of clinical and cell culture complications including the complexity of the multistep surgical procedures, donor-site trauma, immune rejection for allogeneic and xenogeneic cells, cell phenotypic variations due to in-vitro culture techniques, potential tumorigenesis associated with long-term cell expansion, failure of exogenous cell engraftment, and uncertainties and difficulties in the regulatory approval process [4–8]. The difficulties in the clinical application of stem cell transplantation are in strong contrast to the results of multiple experimental studies that demonstrate different levels of efficacy of cell delivery in a number of disease models such as Parkinson's disease [9, 10], blood cancers and diseases [11, 12], and muscle and spinal disorders/injuries [13, 14].
Explication of diffraction lights on an optical imaging system from a Fraunhofer diffraction perspective (2012)

Low-height camera modules are demanded for such applications as cellular phones and vehicles. For designing optical lens, it has widely been recognized that a trade-off exists between reducing the number of lenses and camera resolution. The optical performance of imaging lenses has been improved by diffraction gratings, which have a peculiar inverse dispersion in the wavelength and exhibit the efficacy of correction for chromatic aberration. We can simultaneously reduce the number of lenses and maintain optical resolution using diffraction gratings. However, we have found a generation of striped flare lights under intense light sources that differ from unnecessary order diffraction lights. In this paper, we reveal the generation mechanism of these new striped diffraction lights and suggest a novel structure of diffraction gratings that can decrease them.
Exploiting In-Situ NMR to Monitor the Formation of a Metal-Organic Framework (2019)

The formation processes of metal-organic frameworks are becoming more widely researched using in-situ techniques, although there remains a scarcity of NMR studies in this field. In this work, the synthesis of framework MFM-500(Ni) has been investigated using an in‑situ NMR strategy that provides information on the time-evolution of the reaction and crystallization process. In our in‑situ NMR study of MFM-500(Ni) formation, liquid-phase 1H NMR data recorded as a function of time at 5 fixed temperatures afford qualitative information on the solution-phase processes and quantitative information on the kinetics of crystallization, allowing the activation energies for nucleation and growth to be determined. Ex-situ SAXS studies provide complementary nanoscale information on the rapid self-assembly prior to MOF crystallization and in-situ powder X-ray diffraction confirms that the only crystalline phase present during the reaction is phase-pure MFM-500(Ni).
Distributed Feedback Laser Using Buried Dielectric Grating (2007)

In this paper, we report a DFB laser diode with a buried SiO2 grating. Epitaxy lateral overgrowth by metalorganic chemical vapour deposition (MOCVD) is conducted to grow the p-type InP cladding layers in the nano-patterned dielectric grating template. The large refractive index difference between SiO2 and InP results an index coupling coefficient κ of about 250 cm-1. The fabricated DFB laser showed a side mode suppression ratio larger than 45 dB measured. The technology developed can also be used for other applications that require high efficiency grating structure.

Clinical and Immunological Factors That Distinguish COVID-19 From Pandemic Influenza A(H1N1) (2021)

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), is a global health threat with the potential to cause severe disease manifestations in the lungs. Although COVID-19 has been extensively characterized clinically, the factors distinguishing SARS-CoV-2 from other respiratory viruses are unknown. Here, we compared the clinical, histopathological, and immunological characteristics of patients with COVID-19 and pandemic influenza A(H1N1). We observed a higher frequency of respiratory symptoms, increased tissue injury markers, and a histological pattern of alveolar pneumonia in pandemic influenza A(H1N1) patients. Conversely, dry cough, gastrointestinal symptoms and interstitial lung pathology were observed in COVID-19 cases. Pandemic influenza A(H1N1) was characterized by higher levels of IL-1RA, TNF-α, CCL3, G-CSF, APRIL, sTNF-R1, sTNF-R2, sCD30, and sCD163. Meanwhile, COVID-19 displayed an immune profile distinguished by increased Th1 (IL-12, IFN-γ) and Th2 (IL-4, IL-5, IL-10, IL-13) cytokine levels, along with IL-1β, IL-6, CCL11, VEGF, TWEAK, TSLP, MMP-1, and MMP-3. Our data suggest that SARS-CoV-2 induces a dysbalanced polyfunctional inflammatory response that is different from the immune response against pandemic influenza A(H1N1). Furthermore, we demonstrated the diagnostic potential of some clinical and immune factors to differentiate both diseases. These findings might be relevant for the ongoing and future influenza seasons in the Northern Hemisphere, which are historically unique due to their convergence with the COVID-19 pandemic.
The Schumann‐Runge continuum of oxygen at wavelengths greater than 175 NM (1982)

A highly temperature dependent continuum corresponding to absorption by thermally excited molecules underlies the higher bands of the Schumann‐Runge system of oxygen. This continuum has been experimentally determined at 18 wavelengths in the range 175 nm to 179 nm, and at temperatures of 90°K and 294°K. Calculations of the continuum cross‐section made by solving the Schrödinger equation for the molecular potentials provide good agreement with the measured values. The continuum cross‐section has been calculated at a range of temperatures for use in studies of the atmospheric absorption of solar radiation.
Initiation of Deregulated Growth of Multipotent Progenitor Cells by bcr-abl in Vitro (1992)

Expression of the bcr-abl oncogene in multipotent progenitor cells (MPPCs) is implicated as a key event in the development of chronic myelogenous leukemia. Bone marrow enriched for MPPCs was infected with a retrovirus that carried bcr-abl . The mixed-lineage colonies that resulted were responsive to growth factors and could differentiate. These cells later became growth factor-independent but, when injected into severe combined immunodeficient mice, were not leukemogenic. Thus, the presence of bcr-abl alone does not cause growth factor independence, although it initiates a stepwise process. This system may prove useful in the study of other oncogenes that cause leukemia.

Optimum facet reflectivity for high speed lasers (1990)

The issue of optimum facet reflectivity for large bandwidth semiconductor lasers is addressed. The laser facet reflectivity, is chosen for maximising the relaxation oscillation frequency, by optimisation of the photon lifetime and maximum obtainable intracavity photon density. The optimum mirror reflectivity also depends on the relative importance of photon density-induced facet damage, parasitic leakage, heating, and gain saturation. In practice, we find both theoretically and experimentally, that higher mirror reflectivities can result in higher modulation bandwidths. The issue of optimum mirror reflectivity is also of special interest for surface emitting lasers where the cavity length is very short but the mirror reflectivity is very high.
Collaborative Sensing in Perceptive Mobile Networks: Opportunities and Challenges (2023)

With the development of innovative applications that demand accurate environment information, for example, autonomous driving, sensing becomes an important requirement for future wireless networks. To this end, integrated sensing and communication (ISAC) provides a promising platform to exploit the synergy between sensing and communication, where perceptive mobile networks (PMNs) were proposed to add accurate sensing capability to existing wireless networks. The well-developed cellular networks offer exciting opportunities for sensing, including large coverage, strong computation, communication power, and, most importantly, networked sensing, where the perspectives from multiple sensing nodes can be collaboratively utilized for sensing the same target. However, PMNs also face big challenges, such as the inherent interference between sensing and communication, the complex sensing environment, and the tracking of high-speed targets by cellular networks. This article provides a comprehensive review on the design of PMNs, covering the popular network architectures, sensing protocols, standing research problems, and available solutions. Several future research directions that are critical for the development of PMNs are also discussed.
The influence of surface chemical dynamics on electrical and optical properties of ZnO nanowire field effect transistors (2009)

We demonstrate the effect of surface chemical dynamics on carrier transport and recombination processes of electron-hole pairs in ZnO nanowire field effect transistors. We have found that the electrical conductance decreases and the threshold voltages shift in a positive gate voltage direction, as electrical characteristics are measured repeatedly. We associate this with the enhancement of oxygen adsorption by capturing electrons from the induced current during the probing. This results in an overall depletion of electrons and thus causes the positive shift in threshold voltages associated with the origin and width of characteristic hysteresis loops. In addition, the surface environment dependence of the photo-response related to a recombination process in ZnO nanowires is discussed in terms of the surface chemical reaction and band bending.
