Performance impact of process mapping on small-scale SMP clusters -a case study using high performance linpack (2002)

Typically, a High Performance Computing (HPC) cluster loosely couples multiple Symmetric Multi-Processor (SMP) platforms into a single processing complex. Each SMP uses shared memory for its processors to communicate, whereas communication across SMPs goes through the intra-cluster interconnect. By analyzing the communication pattern of processes, it is possible to arrive at a mapping of processes to processors to ensure optimal communication paths for critical traffic. This critical traffic refers to the communication pattern of the program, which can be characterized by either frequency or size (or both) of the messages. To find an ideal mapping, it is imperative to understand the communication characteristics of the SMP memory system, intra-cluster interconnection, and the Message Passing Interface (MPI) program running on a cluster.Our approach is to study the ideal mapping for two classes of interconnects: 1) standard, high-volume Ethernet interconnects, and 2) proprietary, low-latency high-bandwidth interconnects. In the first installment of our work presented in this paper, we have focused on the ideal mapping for the first class.We configured a 16-node dual-processor cluster, interconnected with Fast Ethernet, Gigabit Ethernet, Giganet, and Myrinet. We used High Performance Linpack (HPL) benchmark to demonstrate that re-mapping of processes to processors (or changing the order of processors used) can affect the overall performance. The mappings are based on the HPL program analysis obtained from running a MPI profiling tool. Our results suggest that the performance of HPL using Fast Ethernet as the interconnect can be improved from 10% to 50% depending on the process mapping and the problem size. Conversely, an ad hoc mapping can adversely affect the cluster performance.
EXPERIMENTAL STUDY FOR TIMBER-BASED RIGID FRAME WITH BOLT AND BOND (2007)

This paper describes the structural performance of tensile bolt with bond on wood post-beam construction. The structural key issue of the moment-resisting joint using this bolt is to evaluate the tensile strength of embedding bolt with bond. Tensile tests in the variant of the dimension, bond, shape of insert hole, embedded-dowel length and so on were carried out. To predict the strength of the bolt, the tests for sliced timber through bolt were also carried out. As the results of their tests and calculations, influencing factors of the bolt were defined and moment-resisting performance was predicted using result of tensile bolt test.
Data-dependent evaluator modeling and its application to emotional valence classification from speech (2010)

Practical supervised learning scenarios involving subjectively evaluated data have multiple evaluators, each giving their noisy version of the hidden ground truth. Majority logic combination of labels assumes equally skilled evaluators, and is generally suboptimal. Previously proposed models have assumed data independent evaluator behavior. This paper presents a data dependent evaluator model, and an algorithm to jointly learn evaluator behavior and a classifier. This model is based on the intuition that real world evaluators have varying performance depending on the data. Experiments on an emotional valence classification task show modest performance improvements of the proposed algorithm as compared to the majority logic baseline and a data independent evaluator model. But more critically, the algorithm also provides accurate estimates of individual evaluator performance, thus paving the way for incorporating active learning, evaluator feedback and unreliable data detection.
Cache Optimization for Mobile Devices Running Multimedia Applications (2005)

The popularity of mobile/wireless embedded systems running multimedia applications is growing. MPEG4 is an important and demanding multimedia application. With improved CPU, memory subsystem deficiency is the major barrier to improving the system performance. Studies show that there is sufficient reuse of values for caching to significantly reduce the raw required memory bandwidth for video data. Decoding MPEG4 video data in software generates many times more cache-memory traffic than required. Proper understanding of the decoding algorithm and the composition of its data set is obvious to improve the performance of such a system. The focus of this paper is to enhance MPEG4 decoding performance through cache optimization of a mobile device. The architecture we simulate includes a digital signal processor (DSP) to run the decoding algorithm and a two-level cache system. Level-1 cache is split into data (D1) and instruction (I1) caches and level-2 (CL2) is a unified cache. We use Cachegrind and VisualSim simulation tools to optimize cache size, line size, associativity, and levels of caches for a wireless device decoding MPEG4 video.
Transparent ion intercalation films of Zr–Ce oxide (1997)

Zr–Ce oxide films were made by reactive dc magnetron cosputtering. The elemental composition was determined by Rutherford backscattering spectrometery and the crystalline structure by x-ray diffraction. Li intercalation/deintercalation was accomplished potentiodynamically in a liquid electrolyte. The films remained fully transparent irrespective of their degree of lithiation, which may be reconciled with a population/depopulation of Ce 4f levels.

Low-loss VIS/IR-XUV beam splitter for high-power applications (2011)

We present a low-loss VIS/IR-XUV beam splitter, suitable for high-power operation. The spatial separation of the VIS/IR and XUV components of a beam is achieved by the wedged top layer of a dielectric multilayer structure, onto which the beam is impinging under Brewster's angle (for VIS/IR). With a fused silica wedge with an angle of 0.5° we achieve a separation angle of 2.2° and an IR reflectivity of 0.9995. Typical XUV reflectivities amount to 0.1-0.2. The novel element is mechanically robust, exhibiting two major advantages over free-standing Brewster plates: (i) a significant improvement of heat conduction and (ii) easier handling, in particular for high-optical-quality fabrication. The beam splitter could be used as an output coupler for intracavity-generated XUV radiation, promising a boost of the power regime of current MHz-HHG experiments. It is also suited for single-pass experiments and as a beam combiner for pump-probe experiments.
Ligand Exchange Reaction of Carbonylhemoglobin to Oxyhemoglobin in a Hemoglobin Liquid Membrane. (1995)

カルボニルヘモグロビソ(H6CO)からオキシヘモグロビン(H6O2)への配位子交換を行うために,酸素気流下HbCO液膜に可視光を照射して光解離させたHbに酸素が結合する挙動を検討した.HHCOの減少速度は照度の増大と共に増大し,照度2.0×105lx(酸素分圧760Torr)で飽和に達した.また,この照度で酸素分圧を760TorrからOTorrまで低下させると速度は1/5に減少した.静止系では液膜厚の増大と共にHbCOの減少速度が低下するが,かきまぜ系では逆に増大した.流動液膜型配位子交換装置を作製して流速とHbCO減少量との関係を求め,Hb小胞体分散系とHb溶液系を比較した結果,Hb小胞体系の方が効率良く配位子交換されることが明らかとなった.
Solution‐Based Synthesis of Submicrometer ZrB 2 and ZrB 2 –TaB 2 (2008)

Zirconium diboride and a zirconium diboride/tantalum diboride mixture were synthesized by solution‐based processing. Zirconium n ‐propoxide was refluxed with 2,4‐pentanedione to form zirconium diketonate. This compound hydrolyzed in a controllable fashion to form a zirconia precursor. Boria and carbon precursors were formed via solution additions of phenol–formaldehyde and boric acid, respectively. Tantalum oxide precursors were formed similarly as zirconia precursors, in which tantalum ethoxide was used. Solutions were concentrated, dried, pyrolyzed (800°–1100°C, 2 h, flowing argon), and exposed to carbothermal reduction heat treatments (1150°–1800°C, 2 h, flowing argon). Spherical particles of 200–600 nm for pure ZrB 2 and ZrB 2 –TaB 2 mixtures were formed.

Porcine and Human Insulin Absorption From Subcutaneous Tissues in Normal and Insulin-Dependent Diabetic Subjects: A Deconvolution-Based Approach* (1988)

The mechanisms of sc insulin absorption are not understood, and models for interpreting in vivo data cannot be developed without gross simplification. To overcome this difficulty we developed a new approach which makes use of deconvolution analysis and does not require any model of the sc tissue. In five normal subjects and seven insulin-dependent diabetic (IDDM) patients endogenous insulin secretion was suppressed by means of a hypoglycemic glucose clamp procedure (∼2.8 mmol/L) sustained by a continuous insulin infusion (∼4 pmol/min · kg). A bolus injection of insulin (5.4 nmol) was administered iv, and plasma insulin concentrations were measured frequently for 2 h to assess iv insulin kinetics. Insulin then was injected sc in the abdominal region, and plasma insulin concentrations were measured for 8 h. Each subject was studied twice, with porcine and semisynthetic human insulin (Actrapid, Novo). The rate of insulin absorption was reconstructed by deconvolution from the plasma concentrations and iv insulin kinetic data. Linearity of the iv insulin kinetics, essential for deconvolution analysis, was confirmed by a dose-response study in the range of the measured concentrations (150–1800 pmol/L). In most instances, a two-compartment model was adequate to describe the iv response. The mean plasma insulin clearance rates were 15.5 ± 1.9 (±sd) mL/min · kg (porcine) and 17.2 ± 6.0 (human) in normal subjects and 20.7 ± 8.8 (porcine) and 20.9 ± 9.1 (human) in the IDDM patients. The rate of appearance of human insulin from sc tissue was faster than that of porcine insulin in both normal and IDDM subjects, but no significant differences were found in bioavailability, which was 55 ± 12% (±sd; porcine) and 61 ± 34% (human) in the normal subjects, and 84 ± 28% (porcine) and 86 ± 23% (human) in the IDDM patients. The rate of absorption and bioavailability were higher in the IDDM patients than in the normal subjects, a difference possibly related to increased sc blood flow in the IDDM patients. No differences were found with regard to glucose requirement values, normalized to plasma insulin concentrations, in agreement with the finding that the bioavailability of the two insulin species was similar.
An Algorithmic Approach to Compute the Effect of Non-Radiative Relaxation Processes in Photoacoustic Spectroscopy (2022)

Successful transfer of photoacoustic gas sensors from laboratory to real-life applications requires knowledge about potential cross-sensitivities towards environmental and gas matrix changes. Multi-dimensional calibration in case of cross-sensitivities can become very complex or even unfeasible. To address this challenge, we present a novel algorithm to compute the collision based non-radiative efficiency and phase lag of energy relaxation on a molecular level (CoNRad) for photoacoustic signal calculation. This algorithmic approach allows to calculate the entire relaxation cascade of arbitrarily complex systems, yielding a theoretical photoacoustic signal. In this work the influence of varying bulk compositions, i.e. nitrogen (N<sub>2</sub>), oxygen (O<sub>2</sub>) and water (H<sub>2</sub>O) on the photoacoustic signal during methane (CH<sub>4</sub>) detection is demonstrated. The applicability of the algorithm to other photoacoustic setups is shown exemplary by applying it to the relaxational system investigated in [1]. Hayden et al. examined the effect of water on photoacoustic carbon monoxide (CO) detection.
Transfer Function design toolbox for full-color volume datasets (2017)

In this paper, we tackle the challenge of effective Transfer Function (TF) design for Direct Volume Rendering (DVR) of full-color datasets. We propose a novel TF design toolbox based on color similarity which is used to adjust opacity as well as replacing colors. We show that both CIE L*u*v* chromaticity and the chroma component of YCbCr are equally suited as underlying color space for the TF widgets. In order to maximize the area utilized in the TF editor, we renormalize the color space based on the histogram of the dataset. Thereby, colors representing a higher share of the dataset are depicted more prominently, thus providing a higher sensitivity for fine-tuning TF widgets. The applicability of our TF design toolbox is demonstrated by volume ray casting challenging full-color volume data including the visible male cryosection dataset and examples from 3D histology.
Quantum-size effect in nonlinear response of metal nanoparticles (2004)

Our study of the third-order susceptibility for Ag-dielectric composite reveals a critical role of saturation of optical transitions between discrete states of conduction electrons in metal quantum dots. Saturation effects lead to a decrease of the local field enhancement factor that is of particular importance for surface-enhanced phenomena.
Synthesis and in vivo evaluation (PIG) of the selective seretonin reuptake inhibitor [11C]NS 2456 (2001)

Abstract We evaluated a new selective serotonin reuptake inhibitor, NS 2456, to determine whether it is suited for use in PET. Racemic NS 2456 [(1RS, 5SR)‐8‐methyl‐3‐[4‐trifluoromethoxy phenyl]‐8‐azabicyclo [3.2.1]oct‐2‐ene] and its N‐demethylated analogue, racemic NS 2463, selectively inhibit serotonin uptake in rat brain synaptosomes. For uses in PET of the living porcine brain, racemic [ 11 C]NS2463 as well as its radiolabelled enantiomers were used. The compounds crossed the blood‐brain‐barrier rapidly and accumulated preferentially in regions rich in serotonin uptake sites. However their binding potentials were relatively low and no stereoselectivity was found. Thus, neither [ 11 C]NS 2456 nor [ 11 C]‐labelled enantiomers are ideal for PET neuroimaging of neuronal serotonin uptake sites.
An Improved Pictet-Spengler Condensation: A Convenient Synthetic Route to Bioactive Manzamine Derivatives (2007)

An improved Pictet-Spengler method for the construction of a modified β-carboline moiety from an α,β-unsaturated aldehyde is described.The Pictet-Spengler reactions between ircinal A (1) and tryptamine derivatives under milder conditions have resulted in shorter reaction times and higher product yields (70 to 89%) with control of stereochemistry.The Pictet-Spengler products (9 and 11) are two new manzamine alkaloids, which display strong activities against Mycobacterium intracellulare with IC 50 values of 0.2 and 0.06 μg/mL, respectively.The first manzamine alkaloid, manzamine A was isolated in 1986 by Higa and coworkers from an Okinawan sponge. 1 The manzamine alkaloids have been to date isolated from more than 17 species of marine sponges from 5 different family groups. 2,3This group of alkaloids has attracted considerable attention due to its biological activity as a novel family of antiparasitic-antibiotics with significant in vivo activity against malaria and Mtb. 4,5The manzamines have an unusual polycyclic skeleton characterized by a β-carboline group attached to a pentacyclic moiety, which comprises an eight-and thirteenmembered ring on a pyrrolo[2,3-i]isoquinoline framework.Both the β-carboline and the eight-membered ring have been linked to the compounds significant antimalarial activity.The formation of diverse libraries at the β-carboline moiety of manzamine starting with the readily available natural compound, ircinal A ( 1) is now possible.][8][9][10][11][12][13] However, most of the reported results involve the use of an aldehyde or activated ketone as a starting material, while reactions using α,β-unsaturated aldehydes receive much less attention.The reported yields from the Pictet-Spengler reaction involving α,β-unsaturated aldehydes

Potential Foldamers Based on an ortho-Terphenyl Amino Acid (2021)

We describe the synthesis and characterization of a new class of oligomers built from a terphenyl-based amino acid. These oligomeric amides are of interest because the adoption of specific conformations could potentially be driven by the coordinated formation of inter-residue hydrogen bonds and aromatic interactions. Although high-resolution structural data have proven inaccessible, circular dichroism and nuclear magnetic resonance studies suggest that the new oligomers fold concomitantly with discrete self-association in chloroform.
Reduced stochasticity in domain wall motion with increasing pinning density in thin Fe films (2011)

We report in this paper the decrease of the stochasticity of magnetization half-reversal time with increasing domain wall (DW) pinning in Fe films investigated by means of time-resolved magneto-optic Kerr microscopy. The domain images in the films reveal that the density of DW pinning sites increases with increasing Fe thickness. However, we found that the stochasticity of the magnetization half-reversal time significantly decreases with increasing DW pinning. The major reason for the reduced stochasticity is shown to be due to a thermally activated DW creep mechanism that becomes dominant during magnetization reversal due to increased DW pinning.

The Effect of Uni-nanoadditive Manufactured Using RF Plasma Processing on Core-shell Structure in MLCC (2009)

Radio frequency (RF) plasma treatment is studied for the size reduction and the spheroidization of coarse particles to change them into nano-sized powders of spherical shape in MLCC fields. The uni-nanoadditives manufactured by RF plasma processing for high dispersion have been investigated for the effect on core-shell structure in dielectrics of MLCC. Microstructures have been characterized using scanning electron microscope (SEM), transmission electron microscope (TEM) and Electron Probe Micro Analyzer (EPMA). We compared the distribution of core-shell grains between specimens manufactured using uni-nanoadditive and using mixed additive. In addition, the uniformity of rare earth elements in the core-shell structured grains was analyzed. It was shown, from TEM observations, that the sintered specimen manufactured using uni-nanoadditives had more dense small grains with well-developed core-shell structure than the specimen using mixed additives, which had a homogeneous microstructure without abnormal grain growth and shows broad temperature coefficient of capacitance (TCC) curves in all temperature ranges because of well dispersed additives.

Effect of Temperature and Pressure on the Dynamic Miscibility of Hydrogen-Bonded Polymer Blends (2004)

The dynamic miscibility of poly(4-vinylphenol)/poly(vinyl ethyl ether) (PVPh/PVEE) blends, with a Tg contrast of 186 K, as well as the PVEE segmental dynamics have been investigated by temperature- and pressure-dependent dielectric spectroscopy. In PVEE the pressure coefficient of Tg amounts to 0.215 K/MPa, and its apparent activation volume displays the usual T dependence. Although both temperature and volume contribute to the segmental dynamics, the former has a stronger influence within the T and P investigated. In the blends, dynamic heterogeneity is suppressed because of hydrogen bonds that couple the components' segmental dynamics. In the PVEE-rich blends, increasing temperature and pressure results in the broadening of the distribution of relaxation times through the weakening of hydrogen bonds and the associated decoupling of the segmental dynamics. A central result of the present study is the identification of a critical temperature above which the system becomes increasingly heterogeneous.
