Microcavity optoelectronic devices (2002)

Over the past few years vertical-cavity surface-emitting lasers and modulators have emerged as viable devices with interesting performance characteristics. One of their key features is that they occupy very little substrate area as compared to most optoelectronic devices. As a result, they also require relatively low drive powers. These aspects together with their suitability for wafer-scale fabrication and testing make them appear suitable for low-cost production as well as high performance. In this paper we shall review recent progress on these devices with emphasis on the vertical-cavity laser. Vertical-cavity lasers with cw powers exceeding 110 mW, overall efficiencies exceeding 17%, operating temperatures exceeding 120/spl deg/C, and output powers insensitive to temperature over ranges exceeding 60/spl deg/C will be illustrated. In addition, devices have operated cw down to diameters of 2 /spl mu/m, including a 6 /spl mu/m device that delivers nearly 2 milliwatts of single-mode output power with greater than 30 dB of spurious mode suppression. In the vertical-cavity modulator area, reflective asymmetric Fabry-Perot structures have given up to 37 GHz of modulation bandwidth. Insertion losses are about 3 dB, and required voltage swings for 100:1 modulation are /spl simspl plusmn/2V.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Commensal Bacteria: Not Just Innocent Bystanders (2019)

<i>Neisseria gonorrhoeae</i> is quickly becoming untreatable due to its acquisition of resistance to multiple antimicrobials. It is vital that we begin to understand the mechanisms by which this is occurring. The paper by C. E. Rouquette-Loughlin, J. L. Reimche, J. T. Balthazar, V. Dhulipala, et al. (mBio 9:e02281-18, https://doi.org/10.1128/mBio.02281-18) has shown that horizontal transfer of DNA from a nasopharyngeal commensal, <i>Neisseria polysaccharea</i>, has resulted in multiple sequence changes in the <i>mtr</i> locus that affect both regulatory and structural regions of the MtrCDE pump, resulting in low-level azithromycin resistance. Studies such as this are increasingly important in our understanding of the movement of resistance between species and for devising strategies to overcome such events.
Characterization of a Mechanically Tunable Gyroid Photonic Crystal Inspired by the Butterfly Parides Sesostris (2015)

A mechanically tunable macroscale replica of the gyroid photonic crystal found in the Parides sesostris butterfly's wing scales is systematically characterized. By monitoring both photonic frequency changes and the distribution of stress fields within the compressed structure, electromagnetic transmission features are found and can be frequency-tuned and the structure only contains localized high stress fields when highly compressed.

Novel Myosin Heavy Chain Kinase Involved in Disassembly of Myosin II Filaments and Efficient Cleavage in MitoticDictyosteliumCells (2002)

We have cloned a full-length cDNA encoding a novel myosin II heavy chain kinase (mhckC) from Dictyostelium. Like other members of the myosin heavy chain kinase family, the mhckC gene product, MHCK C, has a kinase domain in its N-terminal half and six WD repeats in the C-terminal half. GFP-MHCK C fusion protein localized to the cortex of interphase cells, to the cleavage furrow of mitotic cells, and to the posterior of migrating cells. These distributions of GFP-MHCK C always corresponded with that of myosin II filaments and were not observed in myosin II-null cells, where GFP-MHCK C was diffusely distributed in the cytoplasm. Thus, localization of MHCK C seems to be myosin II-dependent. Cells lacking the mhckC gene exhibited excessive aggregation of myosin II filaments in the cleavage furrows and in the posteriors of the daughter cells once cleavage was complete. The cleavage process of these cells took longer than that of wild-type cells. Taken together, these findings suggest MHCK C drives the disassembly of myosin II filaments for efficient cytokinesis and recycling of myosin II that occurs during cytokinesis.
Clinical Severity in CADASIL Related to Ultrastructural Damage in White Matter (1999)

These results indicate that DTI is able to detect important ultrastructural changes in regions with increased signal on T2WI and within the normal-appearing white matter in CADASIL. The diffusion changes might be related to both neuronal loss and demyelination. The degree of the underlying ultrastructural alterations is related to the severity of the clinical status with a possible threshold level of white-matter damage above which severe neurological impairment may occur in this disease. DTI appears to be a promising technique for monitoring disease progression in CADASIL.
Effect of nitrogen on σ transformation in duplex stainless steel weld metal (1999)

AbstractDuplex stainless steels were gas tungsten arc welded without filler material in various Ar–N2 mixed gas atmospheres. Weld metals having different nitrogen contents were annealed at 900–1300 K to examine the single effect of nitrogen on the σ transformation. Nitrogen content of the weld metal did not influence the nose temperature and the time for σ initiation in time–temperature–precipitation diagrams for σ, but did decrease the σ content after annealing for long times. These results were correlated with the nitrogen content and microstructure of the weld metals. The effect of σ on the fracture toughness of the weld metal was evaluated by the small punch (SP) test. A small amount of σ in the weld metal led to a marked decrease in the SP energy.

Simulation code for estimating external gamma-ray doses from a radioactive plume and contaminated ground using a local-scale atmospheric dispersion model (2021)

In this study, we developed a simulation code powered by lattice dose-response functions (hereinafter SIBYL), which helps in the quick and accurate estimation of external gamma-ray doses emitted from a radioactive plume and contaminated ground. SIBYL couples with atmospheric dispersion models and calculates gamma-ray dose distributions inside a target area based on a map of activity concentrations using pre-evaluated dose-response functions. Moreover, SIBYL considers radiation shielding due to obstructions such as buildings. To examine the reliability of SIBYL, we investigated five typical cases for steady-state and unsteady-state plume dispersions by coupling the Gaussian plume model and the local-scale high-resolution atmospheric dispersion model using large eddy simulation. The results of this coupled model were compared with those of full Monte Carlo simulations using the particle and heavy-ion transport code system (PHITS). The dose-distribution maps calculated using SIBYL differed by up to 10% from those calculated using PHITS in most target locations. The exceptions were locations far from the radioactive contamination and those behind the intricate structures of building arrays. In addition, SIBYL's computation time using 96 parallel processing elements was several tens of minutes even for the most computationally expensive tasks of this study. The computation using SIBYL was approximately 100 times faster than the same calculation using PHITS under the same computation conditions. From the results of the case studies, we concluded that SIBYL can estimate a ground-level dose-distribution map within one hour with accuracy that is comparable to that of the full Monte Carlo simulation.
Reconstruction of tissue birefringence from polarization-sensitive optical coherence tomography using machine learning (2021)

Current processing techniques of polarization-sensitive optical coherence tomography (PS-OCT) can recover the tissue’s local, i.e. depth-resolved scalar retardance and optic axis orientation. However, system-induced polarization mode dispersion (PMD) and the presence of speckle in the measured tomograms complicate reconstruction and result in a detrimental trade-off with spatial resolution. We speculate that a machine learning approach should work well for generating an improved reconstruction. By training the model on simulated tomograms that encode the forward model and include system PMD and noise, and by testing the algorithm on experimentally acquired PS-OCT data, we aim to demonstrate a generalized PS-OCT reconstruction tool.
Motion Control of Direct-Drive Motor by a Homogeneous ER Fluid (1999)

Since a direct-drive (DD) motor system doesn't have the reduction gear, the structure of the servo system can be simple and stiff. On the other hand, in the DD system, the disturbance torque directly influences the accuracy of the motor control. The high servo gain is effective and important for reducing the influence of the disturbance torque. However, the high servo control often makes the control system unstable or vibratory. Therefore, the servo gain must be lowered for assuring stability, and the influence of the disturbance becomes serious. In this study, the DD motor system using an ER fluid damper is discussed. By applying the ER damper to the DD motor system, it is possible to obtain the mechanical damping and to realize a high servo gain in the motion control. Finally, the effectiveness of the proposed system is confirmed experimentally.
The succession to Mao and the end of Maoism, 1969–1982 (2011)

The Great Proletarian Cultural Revolution was an attempt to shape the future of China. Its method was to change the nature of the Chinese people. It was to be a “great revolution that touches people to their very souls.” The masses were to liberate themselves by class struggle against the main target, “those within the Party who are in authority and are taking the capitalist road,” These so-called Soviet-style revisionists were alleged to be seeking to corrupt the masses by using old ideas to restore capitalism. By transforming the ideological realm – education, literature, the arts – and embracing Mao Zedong Thought, the Chinese people were to inoculate themselves against poisonous contagion.

Structure-activity studies on 2-aryl-4H-3, 1 -benzoxazin-4-ones (1994)

Eight benzoxazin-4-ones related in structure to NSC 341964 (1) have been tested for cytotoxicity in two different cell systems. Two of the benzoxazin-4-ones (3 and 10) showed good cytotoxicity (ID50 = 9.9 and 8.9 microM) in P388 cells. The nitrobenzoxazin-4-one (10) caused a significant alteration in cell cycle distribution when administered to P388 cells and was an inhibitor of porcine pancreatic elastase. Structure-activity relationships are discussed.

Highly sensitive double‐fluorescent dye staining on microchip electrophoresis for analysis of milk proteins (2008)

We demonstrated a highly sensitive double-fluorescent dye staining in microchip electrophoresis (ME) for analysis of milk proteins. The detection sensitivity of ME was very limited so far and needed improvement. Our staining method consisted of two steps. First, in sample preparation before electrophoresis, protein was covalently bound to an amine-reactive fluorescent dye, Cy5. Then, the Cy5-attached protein was denatured with SDS and was further stained, during electrophoresis, with Agilent fluorescent dye, which was noncovalently attached to hydrophobic regions of the SDS-protein complexes. This double-fluorescent staining enhanced fluorescent intensity and lowered the detection limit to 200 pg of protein. This provided higher sensitivity than silver- or SYPRO Ruby-staining methods, which have previously given the highest sensitivity in protein staining. In addition, we applied our staining method to analysis of milk proteins and achieved their successful detection, whereas it was difficult to analyze them by the unimproved method.
Strength of fibres in low-density thermally bonded nonwovens: An experimental investigation (2012)

Mechanical properties of nonwovens related to damage such as failure stress and strain at that stress depend on deformation and damage characteristics of their constituent fibres. Damage of polypropylene-fibre commercial low-density thermally bonded nonwovens in tension was analysed with tensile tests on single fibres, extracted from nonwovens bonded at optimal manufacturing parameters and attached to individual bond points at both ends. The same tests were performed on raw polypropylene fibres that were used in manufacturing of the analysed nonwovens to study quantitatively the effect of manufacturing parameters on tenacity of fibres. Those tests were performed with a wide range of strain rates. It was found that the fibres break at their weakest point, i.e. bond edge, in optimally bonded nonwovens. Additionally, failure stress and strain in tension of a fibre extracted from the fabric were significantly lower than those of virgin fibre. Since damage in nonwovens occurs by progressive failure of fibres, those experiments were used to establish criteria for damage initiation and propagation in thermally bonded nonwovens based on polypropylene fibres. Moreover, the results obtained from the experiments are useful to simulate the damage behaviour of nonwoven fabrics.

Spatial Degrees of Freedom of the Multicell MIMO Multiple Access Channel (2011)

We consider a homogeneous multiple cellular scenario with multiple users per cell, i.e., $K\geq 1$ where $K$ denotes the number of users in a cell. In this scenario, a degrees of freedom outer bound as well as an achievable scheme that attains the degrees of freedom outer bound of the multicell multiple access channel (MAC) with constant channel coefficients are investigated. The users have $M$ antennas, and the base stations are equipped with $N$ antennas. The found outer bound is general in that it characterizes a degrees of freedom upper bound for $K\geq 1$ and $L&gt;1$ where $L$ denotes the number of cells. The achievability of the degrees of freedom outer bound is studied for two cell case (i.e., L=2). The achievable schemes that attains the degrees of freedom outer bound for L=2 are based on two approaches. The first scheme is a simple zero forcing with $M=Kβ+β$ and $N=Kβ$, and the second approach is null space interference alignment with $M=Kβ$ and $N=Kβ+β$ where $β&gt;0$ is a positive integer.
H3DAtten: Heterogeneous 3-D Integrated Hybrid Analog and Digital Compute-in-Memory Accelerator for Vision Transformer Self-Attention (2023)

After the success of the transformer networks on natural language processing (NLP), the application of transformers to computer vision (CV) has followed suit to deliver unprecedented performance gains on vision tasks, including image recognition and object detection. The multihead self-attention (MHSA) is the key component in transformers, allowing the models to learn the amount of attention paid to each input position. Despite its strong modeling capability, MHSA involves complex operations that make transformers prohibitively costly for hardware deployment. Existing acceleration efforts with conventional hardware platforms are challenged by the memory wall. To alleviate the memory wall problem, compute-in-memory (CIM) is a promising solution by storing all model parameters on-chip in compute-capable memory arrays. The footprint of 2-D CIM designs must, however, expand to accommodate the increasingly larger model sizes. In this work, we present a heterogeneous 3-D integrated (H3D) accelerator to target the MHSA workloads in vision transformers. H3D allows the proposed H3DAtten architecture to combine the merits of resistive random access memory (RRAM)-based analog CIM (ACIM) in 40 nm and static random access memory (SRAM)-based digital CIM (DCIM) in 16 nm. We perform comprehensive signaling and thermal analyses to examine the effects of 3-D stacking on the accelerator. Compared to iso-capacity 2-D baseline designs, the proposed 5-tier H3DAtten accelerator achieves <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$8.4\times $ </tex-math></inline-formula> compute density without experiencing accuracy loss on the ImageNet-1k dataset.
Th1-specific transcription factor T-bet-deficiency - a new model of acute and accelerated chronic vascular allograft rejection (2005)

Objectives: T-bet is a newly identified Th1-specific T-box transcription factor which has been shown to play a central role in Th1 development, through induction of IFN-γ and suppression of the Th2 cytokines IL-4 and IL-5. We investigated its role in a model of fully mismatched cardiac allograft transplantation using T-bet-deficient mice.
Implementation of a speckle correlation based optical lever (SC-OptLev) with extended dynamic range (2019)

A speckle correlation based optical lever (SC-OptLev) is constructed for the measurement of small changes in the angle of orientation of a surface. The dynamic range of SC-OptLev is found to be twice that of a conventional OptLev for the same experimental configurations. Different filtering mechanisms are implemented and the correlation results are compared. Two types of computer automated SC-OptLevs, open source based computing system with a low-cost image sensor and a commercial computing system, are presented with assistive computational modules.
Formation of Conical Carbon Structures on Vapor-Grown Carbon Filaments (2002)

We report two novel conical carbon structures of nano-to-micrometer dimensions that spontaneously grow on the surface of carbon filaments produced by thermal decomposition of certain hydrocarbons. The first carbon structure occurs in the form of an inverted truncated cone attached with its base to the surface of a carbon filament. Another carbon structure grows in the form of a conical spike with an apex angle of 6°. Interestingly, these two structurally dissimilar carbon species can grow adjacent to each other.
An OpenCL™ Deep Learning Accelerator on Arria 10 (2017)

Convolutional neural nets (CNNs) have become a practical means to perform vision tasks, particularly in the area of image classification. FPGAs are well known to be able to perform convolutions efficiently, however, most recent efforts to run CNNs on FPGAs have shown limited advantages over other devices such as GPUs. Previous approaches on FPGAs have often been memory bound due to the limited external memory bandwidth on the FPGA device. We show a novel architecture written in OpenCL(TM), which we refer to as a Deep Learning Accelerator (DLA), that maximizes data reuse and minimizes external memory bandwidth. Furthermore, we show how we can use the Winograd transform to significantly boost the performance of the FPGA. As a result, when running our DLA on Intel's Arria 10 device we can achieve a performance of 1020 img/s, or 23 img/s/W when running the AlexNet CNN benchmark. This comes to 1382 GFLOPs and is 10x faster with 8.4x more GFLOPS and 5.8x better efficiency than the state-of-the-art on FPGAs. Additionally, 23 img/s/W is competitive against the best publicly known implementation of AlexNet on nVidia's TitanX GPU.
