Highly efficient plasmonic tip design for plasmon nanofocusing in near-field optical microscopy (2016)

Near-field scanning optical microscopy (NSOM) combined with plasmon nanofocusing is a powerful nano-analytical tool due to its attractive feature of efficient background suppression as well as light energy compression to the nanoscale. In plasmon nanofocusing-based NSOM, the metallic tip plays an important role in inducing plasmon nanofocusing. It is, however, very challenging to control plasmonic properties of tips for plasmon nanofocusing with existing tip fabrication methods, even though the plasmonic properties need to be adjusted to experimental environments such as the sample or excitation wavelength. In this study, we propose an efficient tip design and fabrication which enable one to actively control plasmonic properties for efficient plasmon nanofocusing. Because our method offers flexibility in the material and structure of tips, one can easily modify the plasmonic properties depending on the requirements. Importantly, through optimization of the plasmonic properties, we achieve almost 100% reproducibility in plasmon nanofocusing in our experiments. This new approach of tip fabrication makes plasmon nanofocusing-based NSOM practical and reliable, and opens doors for many scientists working in related fields.
High-temperature stress in rice [study conducted at IRRI, Philippines] (1981)

When rice is exposed to air temperatures higher than 35 C, heat injuries occur. Clear varietal differences are observed for high temperature injuries at different growth stages. The rice plant appears to be most sensitive to high temperature at flowering. The second most sensitive stage is about 9 days before flowering. High temperature during anthesis induces high percentages of spikelet sterility. The occurrence of sterility can be attributed to disturbed pollen shedding and impaired pollen germination but not to inactivated pistil. Early morning anthesis is considered one way to avoid high temperature stress. Oryza glaberrima flowers open 3 hrs earlier than IR 36, O. sativa. Some O. sativa and O. glaberrima crosses have anthesis earlier than IR 36. Studies of the genetics of high temperature-induced sterility indicate that heat tolerance has a fairly high heritability and that most genetic variation is additive. There are clear varietal differences in high temperature-induced sterility at anthesis. Both heat-tolerant and early-maturing varieties can be found from the existing variety stocks. A comparison between phytotron and field experiments confirmed that the phytotron can be used for screening for heat tolerance
Hidradenitis suppurativa: a disease of the absent sebaceous gland? Sebaceous gland number and volume are significantly reduced in uninvolved hair follicles from patients with hidradenitis suppurativa (2011)

Our results suggest that the absence or reduced volume of the sebaceous gland may play a role in the pathogenesis of HS. The presence of fibrosis suggests that sebaceous glands are obliterated early in the pathogenesis of HS.
Direct Observation of Hydrogen Tunneling Dynamics in Photoexcited Phenol (2012)

The excited-state dynamics of phenol following ultraviolet (UV) irradiation have received considerable interest in recent years, most notably because they can provide a model for understanding the UV-induced dynamics of the aromatic amino acid tyrosine. Despite this, there has been some debate as to whether hydrogen tunneling dynamics play a significant role in phenol's excited-state O-H bond fission when UV excitation occurs below the (1)ππ*/(1)πσ* conical intersection (CI). In this Letter, we present direct evidence that (1)πσ*-mediated O-H bond fission below the (1)ππ*/(1)πσ* CI proceeds exclusively through hydrogen tunneling dynamics. The observation of hydrogen tunneling may have some parallels with proton tunneling dynamics from tyrosine residues (along the O-H bond of the phenol moiety) in a wide range of natural enzymes, potentially adding further justification for utilizing phenols as model systems for investigating tyrosine-based dynamics.
A Comparative Study of the Incidence of Anergy in Patients with Carcinoma, Leukemia, Hodgkin’s Disease and Other Lymphomas (1962)

Summary Delayed hypersensitivity to a battery of six microbial antigens and one control solution was tested in 400 patients, including 208 controls and 192 with Hodgkin’s disease, carcinoma, leukemia and non-Hodgkin’s lymphoma. Fifty-three per cent of the Hodgkin’s disease group were anergic early in the course of the disease, in contrast to the low incidence among the other patient groups judged to be in good condition on clinical grounds. Anergy was more frequent in all groups when the disease was advanced and the general physical condition of the patients was regarded as poor. Possible mechanisms and significance of this anergy are discussed.

Quorum-Based Perfect Failure Detection Service (2009)

A failure detection service is perfect if it eventually detects all failures and every detection correctly identifies a failure that has already occurred. Such a perfect failure detection service serves as a basic building block for many reliable distributed systems, for example in primary/backup replication protocols and distributed lock services. In this paper, we present a comprehensive study on applying quorum systems to the perfect failure detection service in order to enhance the fault tolerance of the service. We provide the precise system model and specification for a quorum-based failure detection service. We prove that stable storage is necessary if the server processes may crash and recover in the middle of the service. We present two novel algorithms that implement the failure detection service and have complementary characteristics. We further develop a set of quality-of-service (QoS) metrics for quorum-based perfect failure detection services, and apply probabilistic analysis to quantify the QoS metrics of the two algorithms.

Dynamic memory balancing for virtual machines (2009)

Virtualization essentially enables multiple operating systems and applications to run on one physical computer by multiplexing hardware resources. A key motivation for applying virtualization is to improve hardware resource utilization while maintaining reasonable quality of service. However, such a goal cannot be achieved without efficient resource management. Though most physical resources, such as processor cores and I/O devices, are shared among virtual machines using time slicing and can be scheduled flexibly based on priority, allocating an appropriate amount of main memory to virtual machines is more challenging. Different applications have different memory requirements. Even a single application shows varied working set sizes during its execution. An optimal memory management strategy under a virtualized environment thus needs to dynamically adjust memory allocation for each virtual machine, which further requires a prediction model that forecasts its host physical memory needs on the fly. This paper introduces MEmory Balancer (MEB) which dynamically monitors the memory usage of each virtual machine, accurately predicts its memory needs, and periodically reallocates host memory. MEB uses two effective memory predictors which, respectively, estimate the amount of memory available for reclaiming without a notable performance drop, and additional memory required for reducing the virtual machine paging penalty. Our experimental results show that our prediction schemes yield high accuracy and low overhead. Furthermore, the overall system throughput can be significantly improved with MEB.
[The effection of obstructing OCB with strychnine on the guinea pig's DPOAE]. (1998)

The strychnine was used to obstruct the oliver cochlear bundle (OCB) in order to explore the effect of the efferent system on distortion product otoacoustic emission (DPOAE) of guinea pig. The result showed that the DPOAE were not changed after strychnine were administrated. It is concluded that the efferent pulses of the CNS does not affect on DPOAE in silent circumstance.

Spectral emphasis as an additional source of information in accent detection (2001)

This study deals with the relevance of spectral emphasis for accent detection. Spectral emphasis may be described as an acoustic feature reflecting the relative intensity in the higher frequency bands. In an experiment using a rudimentary accent detector, spectral emphasis was shown to be more useful for the detection of accents than overall intensity. Furthermore, spectral emphasis was found to outperform f 0 in certain conditions. It is argued here, therefore, that it might be worthwhile to include spectral emphasis in systems using a combination of acoustic features for automatic classification of prosodic categories.
The taxonomic identity and physiological ecology of<i>Chlamydomonas hedleyi</i>sp. nov. algal flagellate symbiont from the foraminifer<i>Archaias angulatus</i> (1974)

The fine structure of the symbiotic alga isolated from the formainiferan Archaias angulatus (Fichtel et Moll) DeMontfort is typical of the Chlorophyceae of the volvocalean and chlorococcalean lines. Spherical non-motile cells, 10–14 μm in diameter, characterise the dominant life cycle phase. Long oval motile forms with truncated apices are present 3–5 days after transfer to fresh medium. The pyrenoids are embedded anteriorly in the singly bilobed chloroplast and are surrounded by a sheath of starch platelets. In spite of the non-motile state of cells in older cultures (which is perhaps a reflection of its normally symbiotic condition), the alga is identified as a species of the volvocalean genus Chlamydomonas and is named C. hedleyi sp. nov. The symbiont has no vitamin or organic requirements but growth is increased threefold in the presence of thiamine, and twofold in the presence of 1 μm glutamic acid, histidine and methionine. Urea was the best nitrogen source tested. Purines and pyrimidines did not serve as nitrogen sources. Chlamydomonas hedleyi grows well in a salinity range of 6->52‰. and a pH range of 6–8·5, 7·04 × 10-7 m carbon h-1 g-1 was fixed by the symbiont, 57% being released into the medium as a chromatographically homogeneous organic molecule provisionally identified as mannitol.
Cardiac optogenetics (2012)

For therapies based on human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes (CM) to be effective, arrhythmias must be avoided. Towards achieving this goal, light-activated channelrhodopsin-2 (ChR2), a cation channel activated with 480 nm light, and a first generation halorhodopsin (NpHR1.0), an anion pump activated by 580 nm light, have been introduced into hiPSC. By using in vitro approaches, hiPSC-CM are able to be optogenetically activated and inhibited. ChR2 and NpHR1.0 are stably transduced into undifferentiated hiPSC via a lentiviral vector. Via directed differentiation, both wildtype hiPSC-CM (hiPSC(WT)-CM) and hiPSC(ChR2/NpHR)-CM are produced and subjected to both electrical and optical stimulation. Both hiPSC(WT)-CM and hiPSC(ChR2/NpHR)-CM respond to traditional electrical stimulation and produce similar contractility features but only hiPSC(ChR2/NpHR)-CM can be synchronized and inhibited by optical stimulation. Here it is shown that light sensitive proteins can enable in vitro optical control of hiPSC-CM. For future therapy, in vivo optical stimulation could allow precise and specific synchronization of implanted hiPSC-CM with patient cardiac rates and rhythms.
Automated deployment and Aggregated access control for SOA composite applications (2007)

Modeling, assembling, deploying and managing composite applications built using service oriented architectures (SOA) present many interesting challenges. Among these challenges, we consider two: service deployment and security management for access control. In this application session, these challenges are explored in the context of a prototype banking application: "Jivaro". The Jivaro prototype has features such as automated and configurable business processes using BPEL and manual tasks, multitenancy using virtual portals, and security using LDAP. We focus on two specific management pain points: 1. the difficulty in deploying multiple SOA components into multiple target middleware containers, and 2. inconsistency in access control policies for multi-tier applications. For addressing the deployment issues, we present a real-wo rid deployment scenario involving the use of ANT tasks and scripting interfaces. For addressing inconsistencies in access control policies, we present a solution using the XACML standard, a common authorization model developed as an extension of the Java authorization contract for containers and a common policy store and policy administration point. We compare and contrast current access control policies for J2EE containers and databases with the proposed new common authorization model. We also compare separate access control policy stores versus the proposed solution for a common store. Our aggregated role based authorization model provides consistent access control policies that complement single sign-on and identity propagation schemes. This model also touches upon issues surrounding role and policy based management, specifically regarding the potential of combining security policy administrator roles for different tiers.
The first dynamic phase at turn-on of a thyristor (1976)

The first dynamic phase is characterized by a rapid voltage decay during which electron transport by field effects inside the space-charge layer (SCL) in the base region of an n-base thyristor are supposed to dominate. If the external circuit does not impose a voltage-current dependence, a simple one-dimensional model can be formulated which is based on mobile charges affecting the SCL. Comparison with electrical data about turn-on yields approximate information concerning the effective area of the initially conducting channel which is in good agreement with infrared observation. In conjunction with this model, the electrical measurements lead to a simple method to detect failure of a thyristor to turn on homogeneously.
Ultrasonographic Features of Focal Xanthogranulomatous Pyelonephritis (2004)

There were no specific ultrasonographic features that allow for the distinction between focal xanthogranulomatous pyelonephritis and renal tumors or abscesses. Focal xanthogranulomatous pyelonephritis should be considered when there are clinical signs of infection or inflammation and a focal solid mass is seen on ultrasonography.
High expression of CD20+ lymphocytes in soft tissue sarcomas is a positive prognostic indicator (2012)

The immune status is important in cancer patients. Tissue microarrays from 249 patients with soft tissue sarcomas were constructed. Immunohistochemistry was used to evaluate the CD3+, CD4+, CD8+, CD20+ and CD45+ lymphocytes in tumors. High density of CD20+ lymphocytes is an independent positive prognostic indicator for these patients.

Centroid Neural Network With a Divergence Measure for GPDF Data Clustering (2008)

An unsupervised competitive neural network for efficient clustering of Gaussian probability density function (GPDF) data of continuous density hidden Markov models (CDHMMs) is proposed in this paper. The proposed unsupervised competitive neural network, called the divergence-based centroid neural network (DCNN), employs the divergence measure as its distance measure and utilizes the statistical characteristics of observation densities in the HMM for speech recognition problems. While the conventional clustering algorithms used for the vector quantization (VQ) codebook design utilize only the mean values of the observation densities in the HMM, the proposed DCNN utilizes both the mean and the covariance values. When compared with other conventional unsupervised neural networks, the DCNN successfully allocates more code vectors to the regions where GPDF data are densely distributed while it allocates fewer code vectors to the regions where GPDF data are sparsely distributed. When applied to Korean monophone recognition problems as a tool to reduce the size of the codebook, the DCNN reduced the number of GPDFs used for code vectors by 65.3% while preserving recognition accuracy. Experimental results with a divergence-based k-means algorithm and a divergence-based self-organizing map algorithm are also presented in this paper for a performance comparison.

Engineering Mechanics and Analysis of Metal-Matrix Composites (2001)

Abstract The goal of micromechanics and analysis is to use the predictive methodology to develop tailored composites and also to make accurate predictions of their performance in service. This article reviews results derived from micromechanics analyses, based on finite-element method of unidirectional fiber reinforced metal matrix composites (MMCs). It discusses the elastic deformation and elastic-plastic deformation analysis of discontinuously reinforced MMCs. The article provides an overview of analysis of strength, fatigue, and fracture toughness for macromechanics fiber-reinforced and discontinuous reinforced composites.
Plasma-enhanced mixing and flameholding in supersonic flow (2015)

The results of experimental study of plasma-based mixing, ignition and flameholding in a supersonic model combustor are presented in the paper. The model combustor has a length of 600 mm and cross section of 72 mm width and 60 mm height. The fuel is directly injected into supersonic airflow (Mach number M=2, static pressure P(st)=160-250 Torr) through wall orifices. Two series of tests are focused on flameholding and mixing correspondingly. In the first series, the near-surface quasi-DC electrical discharge is generated by flush-mounted electrodes at electrical power deposition of W(pl)=3-24 kW. The scope includes parametric study of ignition and flame front dynamics, and comparison of three schemes of plasma generation: the first and the second layouts examine the location of plasma generators upstream and downstream from the fuel injectors. The third pattern follows a novel approach of combined mixing/ignition technique, where the electrical discharge distributes along the fuel jet. The last pattern demonstrates a significant advantage in terms of flameholding limit. In the second series of tests, a long discharge of submicrosecond duration is generated across the flow and along the fuel jet. A gasdynamic instability of thermal cavity developed after a deposition of high-power density in a thin plasma filament promotes the air-fuel mixing. The technique studied in this work has weighty potential for high-speed combustion applications, including cold start/restart of scramjet engines and support of transition regime in dual-mode scramjet and at off-design operation.
Evaluation of the <sup>13</sup>CO<sub>2</sub> kinetics in humans after oral application of sodium bicarbonate as a model for breath testing (1993)

The kinetics of 13CO2 have been investigated following oral administration at five doses between 12.5 and 100 mg of 13C labelled sodium bicarbonate to 10 healthy subjects in a randomized study. Sodium bicarbonate in this study served as a model compound for carbon dioxide/bicarbonate generated in breath tests. Exhalation of 13CO2 into breath was monitored by stable isotope ratio mass spectrometry. The kinetics of 13CO2 were characterized by an apparent terminal elimination half-life of 1 h and a mean recovery of 0.630 of the dose administered. The kinetics were not dose-dependent. These results were in agreement with the findings reported previously after i.v. application of sodium bicarbonate.
Breast Ultrasound Update (2006)

Continuing advances in computing and equipment are increasing the efficacy of breast ultrasound. A few recent significant advances are described. Cine loop, extended field of view and 3D imaging provide improved demonstration of abnormality. With colour Doppler, ultrasound contrast and ultrasound elasticity, imaging these advances can help to improve diagnostic accuracy and monitoring of presurgical breast cancer treatment.
