Manipulating resource allocation in plants (2012)

The distribution of nutrients and assimilates in different organs and tissues is in a constant state of flux throughout the growth and development of a plant. At key stages during the life cycle profound changes occur, and perhaps one of the most critical of these is during seed filling. By restricting the competition for reserves in Arabidopsis plants, the ability to manipulate seed size, seed weight, or seed content has been explored. Removal of secondary inflorescences and lateral branches resulted in a stimulation of elongation of the primary inflorescence and an increase in the distance between siliques. The pruning treatment also led to the development of longer and larger siliques that contained fewer, bigger seeds. This seems to be a consequence of a reduction in the number of ovules that develop and an increase in the fatty acid content of the seeds that mature. The data show that shoot architecture could have a substantial impact on the partitioning of reserves between vegetative and reproductive tissues and could be an important trait for selection in rapid phenotyping screens to optimize crop performance.
Automated Storage Tiering Using Markov Chain Correlation Based Clustering (2012)

In this paper, we develop an automated and adaptive framework that aims to move active data to high performance storage tiers and inactive data to low cost/high capacity storage tiers by learning patterns of the storage workloads. The framework proposed is designed using efficient Markov chain correlation based clustering method (MCC), which can quickly predict or detect any changes in the current workload based on what the system has experienced before. The workload data is first normalized and Markov chains are constructed from the dynamics of the IO loads of the data storage units. Based on the correlation of one-step Markov chain transition probabilities k-means method is employed to group the storage units that have similar behavior at each point. Such framework can then easily be incorporated in various resource management policies that aim at enhancing performance, reliability, availability. The predictive nature of the model, particularly makes a storage system both faster and lower-cost at the same time, because it only uses high performance tiers when needed, and uses low cost/high capacity tiers when possible.
The Chromatin-binding Protein HMGN1 Regulates the Expression of Methyl CpG-binding Protein 2 (MECP2) and Affects the Behavior of Mice (2011)

High mobility group N1 protein (HMGN1), a nucleosomal-binding protein that affects the structure and function of chromatin, is encoded by a gene located on chromosome 21 and is overexpressed in Down syndrome, one of the most prevalent genomic disorders. Misexpression of HMGN1 affects the cellular transcription profile; however, the biological function of this protein is still not fully understood. We report that HMGN1 modulates the expression of methyl CpG-binding protein 2 (MeCP2), a DNA-binding protein known to affect neurological functions including autism spectrum disorders, and whose alterations in HMGN1 levels affect the behavior of mice. Quantitative PCR and Western analyses of cell lines and brain tissues from mice that either overexpress or lack HMGN1 indicate that HMGN1 is a negative regulator of MeCP2 expression. Alterations in HMGN1 levels lead to changes in chromatin structure and histone modifications in the MeCP2 promoter. Behavior analyses by open field test, elevated plus maze, Reciprocal Social Interaction, and automated sociability test link changes in HMGN1 levels to abnormalities in activity and anxiety and to social deficits in mice. Targeted analysis of the Autism Genetic Resource Exchange genotype collection reveals a non-random distribution of genotypes within 500 kbp of HMGN1 in a region affecting its expression in families predisposed to autism spectrum disorders. Our results reveal that HMGN1 affects the behavior of mice and suggest that epigenetic changes resulting from altered HMGN1 levels could play a role in the etiology of neurodevelopmental disorders.
Nanoimprinted ultrafine line and space nanogratings for liquid crystal alignment (2012)

Ultrafine 50 nm line and space nanogratings were fabricated using nanoimprint lithography, and were further used as an alignment layer for liquid crystals. The surface morphologies of the nanogratings were characterized and their surface energies were estimated through the measurement of the contact angles for two different liquids. Experimental results show that the surface energies of the nanogratings are anisotropic: the surface free energy towards the direction parallel to the grating lines is higher than that in the direction perpendicular to the grating lines. Electro-optical characteristics were tested from a twisted nematic liquid crystal cell, which was assembled using two identical nanogratings. Experimental results show that such a kind of nanograting is promising as an alternative to the conventional rubbing process for liquid crystal alignment.
<title>Process group management in cross-layer adaptation</title> (2003)

Our previous MMCN03 paper reported a cross-layer adaptation framework, GRACE-1, that coordinates the adaptation of CPU frequency/voltage, CPU scheduling, and application quality. GRACE-1 assumes that all application processes (or threads) are independent from each other and adapt individually. This assumption, however, is invalid for multi-threaded applications that include dependent and cooperative processes. To support the joint performance requirements of such dependent processes, this paper extends GRACE-1 with a process group management mechanism. The enhanced framework, called <i>GRACE-grp</i>, introduces a new OS abstraction, <i>group control block</i>, to provide the OS-level recognition and support of process groups. Through a group control block, dependent processes can explicitly set up a group and specify their dependency in the OS kernel. Consequently, GRACE-grp schedules and adapts them in a synchronized and consistent manner, thereby delivering joint performance guarantees. We have implemented and evaluated the GRACE-grp framework. Our experimental results show that compared to GRACE-1, GRACE-grp provides better support for the joint quality of dependent processes and reduces CPU energy consumption by 6.2% to 8.7% for each process group.
Polyelectrolyte multilayers generated in a microfluidic device with pH gradients direct adhesion and movement of cells (2011)

In this study, multilayers from polyethylene imine, heparin and chitosan are prepared at three different pH values of 5, 7 and 9. Water contact angle and quartz microbalance measurements show that resulting multilayers differ in terms of wetting behaviour, layer mass and mechanical properties. The multilayer is then formed within a gradient generation microfluidic (μFL) device. Polyethylene imine or heparin solutions of pH 5 are introduced into one inlet and the same solutions but at pH 9 into another inlet of the μFL device. The pH gradient established during the multilayer formation can be visualized inside the microchamber by pH sensitive fluorophores and confocal laser scanning microscopy. From this setup it is expected that properties of multilayers displayed at distinct pH values can be realised in a gradient manner inside the μFL device. Behaviour of the osteoblast cell line MG-63 seeded and cultured on top of multilayers created inside the μFL device support this hypothesis. It is observed that more cells adhere and spread on multilayers build-up at the basic side of the μFL channel, while those cells on top of multilayers built at pH 5 are fewer and smaller. These results are consistent with the behaviour of MG-63 cells seeded on multilayers formed at discrete pH values. It is particularly interesting to see that cells start to migrate from multilayers built at pH 5 to those built at pH 9 during 6 h of culture. Overall, the presented multilayer formation setup applying pH gradients leads to surfaces that promote migration of cells.
Evaluating Si-Based Materials for Li-Ion Batteries in Commercially Relevant Negative Electrodes (2014)

Methods and criteria for assessing the commercial viability of Si-based materials are discussed and demonstrated with the 3M V6 alloy and 60 nm nano Si powder. These materials are firstly evaluated through the cycling of neat electrodes containing only alloy and binder to characterize the capacity, first cycle efficiency, binder compatibility, and microstructure stability of the material. The alloy displays higher first cycle efficiency, lower fade, and a more stable amorphous microstructure compared to the nano Si, which displays a variable microstructure with a rate dependent presence of crystalline Li15Si4. The materials are then evaluated in graphite-containing composite electrodes having high areal capacities (> 2 mAh/cm2). In a well designed composite electrode including carbon nanotubes, 3M V6 material was found to cycle with little fade and high coulombic efficiency (∼99.8%) while maintaining a stable dQ/dV. A composite electrode of equivalent volumetric capacity with nano Si powder shows similar capacity retention over 50 cycles but an unacceptably low coulombic efficiency (∼99.2%). High precision coulometry and calorimetry results show surface area as the dominant factor in levels of parasitic reactions with Si based materials.
Wave-function mapping in multiple quantum wells using diluted magnetic semiconductors (1999)

We have shown that in symmetric multiple quantum wells (QW's), wave functions of the lowest multiplet of states have rather surprising distributions, where some states are localized only in certain wells, and are totally absent in other wells. To demonstrate this experimentally, we have used magnetoabsorption measurements to map out the distribution of wave functions in multiple-quantum-well structures in which some layers consist of diluted magnetic semiconductors (DMS's). For this purpose we fabricated triple- and quintuple-QW systems consisting of ${\mathrm{Zn}}_{1\ensuremath{-}x\ensuremath{-}y}{\mathrm{Cd}}_{x}{\mathrm{Mn}}_{y}\mathrm{Se}$ (DMS) and ${\mathrm{Zn}}_{1\ensuremath{-}x}{\mathrm{Cd}}_{x}\mathrm{Se}$ (non-DMS) wells, separated by ZnSe (i.e., nonmagnetic) barriers. Transitions involving the lowest multiplet of states (i.e., the ground state split by interwell interactions) were clearly observed and well resolved at zero magnetic field. The wave-function behavior in multiple quantum wells of equal depth was investigated by observing the Zeeman splitting of the optical transitions at 30 K, where the Zeeman splitting of DMS band edges is small compared to the band offset, so that the wells remain in near-resonant condition. This in turn results in strong (resonant) interactions between the wells. The experiments clearly demonstrated that for certain states there are wells in which the probability of finding an electron or a hole vanishes.
Distinct Pathogenic Sequela in Rhesus Macaques Infected with CCR5 or CXCR4 Utilizing SHIVs (1999)

Infection of macaques with chimeric simian-human immunodeficiency virus (SHIV) provides an excellent in vivo model for examining the influence of envelope on HIV-1 pathogenesis. Infection with a pathogenic CCR5 (R5)-specific enveloped virus, SHIVSF162P, was compared with infection with the CXCR4 (X4)-specific SHIVSF33A.2. Despite comparable levels of viral replication, animals infected with the R5 and X4 SHIV had distinct pathogenic outcomes. SHIVSF162P caused a dramatic loss of CD4+ intestinal T cells followed by a gradual depletion in peripheral CD4+ T cells, whereas infection with SHIVSF33A.2 caused a profound loss in peripheral T cells that was not paralleled in the intestine. These results suggest a critical role of co-receptor utilization in viral pathogenesis and provide a reliable in vivo model for preclinical examination of HIV-1 vaccines and therapeutic agents in the context of the HIV-1 envelope protein.
Cluster-based architecture relying on Optical Integrated Networks with the provision of a low-latency arbiter (2016)

State-of-art Multiprocessor Systems-on-Chip (MPSoC) struggle to respect the increasing requirements of high performance interconnects for high throughput communications. Optical integrated Networks (OIN) represent currently one of the most promising paradigms for the design of such next generation MPSoC. They provide increased bandwidth and better reaction to electromagnetic noise while decreasing latency and power consumption. In this paper we propose a new cluster-based architecture, the Hybrid Torus MPSoC (HTM). We propose also a low-latency arbiter allowing to exploit the full potential of the HTM architecture. Our experiments, based on FPGA prototyping and simulation, show the efficiency of the proposed architecture.
A Cross-Metathesis Route to the 5-F2-Isoprostanes (2008)

A library of eight 5-F(2)-isoprostanes was prepared through a ring-opening metathesis/cross-metathesis protocol between functionalized bicyclo[3.2.0]heptenes, ethylene, and alpha,beta-unsaturated ketones. This sequence provided racemic enones in a regio- and stereoselective fashion that could be converted to enantiomerically enriched allylic alcohols through a catalyst-controlled asymmetric reduction. Completion of the sidechains, followed by global deprotection, resulted in a stereodivergent route to eight enantiomerically enriched 5-F(2)-isoprostanes. Overall, the synthesis of this library of known and anticipated lipid oxidation metabolites was achieved in 10 steps from commercially available 4-hydroxy-2-cyclopentenone.
1P-G05 Development of Single-passenger Mobility-Support Robot "ROPITSR^[○!R]" : Recovery from Position Lost Using Similar Images (2015)

We are developing a mobility-support robot "ROPITS" traveling on pedestrian road autonomously to realize a next generation short-distance transportation system in compact-cities. In order to raise the level of autonomous navigating technologies to a practical use, we have made various experiments of autonomous running on the public pedestrian road in the Mobility Robot Experiment Special District in Tsukuba-city, Ibaraki prefecture. We found some places of this district having large position errors, caused by map-matching failures. Therefore, we introduce the recovery method. In this paper, we show the validity of our proposal method and comparison with existing technique.
Wake Unsteadiness and Tip Vortex System of Full-Scale Helicopters in Ground Effect (2021)

The main rotor wake of free–flying helicopters in ground effect was investigated during a measurement campaign with the DLR test rotorcraft Airbus Bo105 and EC135. An advanced measurement system combined high–speed schlieren imaging with point–wise constant temperature anemometry for a comprehensive analysis of the flow. In hover conditions, the wake structure was similar to earlier data, in spite of the environmental conditions, which were found to have a significant influence. The schlieren system tracked the blade tip vortices convecting along the slipstream boundary. Depending on the rotorcraft, the vortices developed either instabilities of individual filaments or cooperative pairing instabilities. Both instability types occurred one to two revolutions below the rotor plane, and the decayed tip vortices fell below the schlieren sensitivity limit soon after. The velocity footprint of the vortices was detected by fiber–film sensors further downstream along the slipstream boundary, but harmonic oscillations play a minor role in comparison to broad–banded turbulence with a Kolmogorov–like spectrum. The wake was found to be hover–like for vertical take–off cases until breaking down into low–frequency oscillations when exceeding a hub height of approximately 1.4 rotor radii. In forward flight conditions, blade–vortex interactions were found in the frontal area of the main rotor plane, and between the main rotor tip vortices and the Bo105’s tail rotor.
Abstract 14526: The Effect of Radiofrequency Catheter Ablation of Typical Atrial Flutter on Cardiac Chambers' Size and Function (2020)

Introduction: Cavo-tricuspid isthmus (CTI) dependent atrial flutter (AFL) is one of the most common atrial arrhythmias involving the right atrium (RA) for which radiofrequency catheter ablation has been widely used as a therapy of choice. However, there is limited data on the effect of this intervention on cardiac size and function. Hypothesis: CTI dependent ablation for patients with AFL will improve tricuspid valve function, biatrial enlargement, and ventricular function. Methods: A retrospective study was conducted on 468 patients who underwent CTI dependent ablation for clinical typical AFL at a single institution between 2010 and 2019. After patients with congenital or rheumatic heart disease, heart transplant recipients, or those without baseline echocardiogram were excluded, 211 patients remained in the analysis. Echocardiographic data were analyzed at baseline prior to ablation, and at early follow-up within 1-year post-ablation. Follow-up echocardiographic data was available for 130 patients. Results: Of the 211 patients with CTI-AFL, 200 had typical counterclockwise flutter. The mean age was 64.2±12.1 years old with 12% (n=26) female. The average left ventricular (LV) ejection fraction (EF) significantly improved on follow-up echo (45.55±14.26 to 49±14.4%, p=0.0075), of which 63 (48%) patients had an improvement in EF of 5% or more and 19 (25%) patients had an increased EF of 20% or more. The prevalence of moderate to severe tricuspid regurgitation (TR) was 24% (n=50) at baseline and 18% (n=22) at follow-up with no significant difference (p=0.27). However, 30% (n=39) of the patients had one grade or more improvement in their TR within the 1-year follow-up. Echocardiography also showed improvement of RA size in 48.6%, and left atrial (LA) size in 48.2% of the patients. Conclusions: Patients who underwent CTI dependent AFL ablation showed an improvement in cardiac size and function at follow-up evaluation. Although longer-term results are unknown, these findings suggest that restoration of sinus rhythm from atrial flutter is associated with improvement in TR severity, RA size, LA size, and LVEF.
Properties and swelling characteristics of cross‐linked poly(vinyl alcohol)/chitosan blend membrane (1992)

Abstract Blend membrane consisting of poly(vinyl alcohol) (PVA) and chitosan was prepared from a solvent‐casting technique and characterized for their intermolecular interactions using infrared and X‐ray diffraction methods. Cross‐linking the blend with glutaraldehyde produces a membrane with lower crystallinity and a smaller swelling degree, but having improved thermostability and mechanical properties. The present blend membrane shows a pH‐dependent swelling characteristic and will be discussed in detail. © 1992 John Wiley &amp; Sons, Inc.
Informational Space of Meaning for Scientific Texts (2020)

In Natural Language Processing, automatic extracting the meaning of texts constitutes an important problem. Our focus is the computational analysis of meaning of short scientific texts (abstracts or brief reports). In this paper, a vector space model is developed for quantifying the meaning of words and texts. We introduce the Meaning Space, in which the meaning of a word is represented by a vector of Relative Information Gain (RIG) about the subject categories that the text belongs to, which can be obtained from observing the word in the text. This new approach is applied to construct the Meaning Space based on Leicester Scientific Corpus (LSC) and Leicester Scientific Dictionary-Core (LScDC). The LSC is a scientific corpus of 1,673,350 abstracts and the LScDC is a scientific dictionary which words are extracted from the LSC. Each text in the LSC belongs to at least one of 252 subject categories of Web of Science (WoS). These categories are used in construction of vectors of information gains. The Meaning Space is described and statistically analysed for the LSC with the LScDC. The usefulness of the proposed representation model is evaluated through top-ranked words in each category. The most informative n words are ordered. We demonstrated that RIG-based word ranking is much more useful than ranking based on raw word frequency in determining the science-specific meaning and importance of a word. The proposed model based on RIG is shown to have ability to stand out topic-specific words in categories. The most informative words are presented for 252 categories. The new scientific dictionary and the 103,998 x 252 Word-Category RIG Matrix are available online. Analysis of the Meaning Space provides us with a tool to further explore quantifying the meaning of a text using more complex and context-dependent meaning models that use co-occurrence of words and their combinations.
Crosstalk and Error Probability in Counter-Beam λ-Multiplexed Digital Holograms (1992)

The recently proposed method for wavelength multiplexed holograms (1) raises the fundamental issues of crosstalk and error probability in such holograms. As a result we pose the following question: A crystal with N stored λ-holograms is illuminated with, say, λ 1 in order to project out (read) hologram #1.
Assignment of the porcine loci for MYOD1 to chromosome 2 and MYF5 to chromosome 5 (1997)

Porcine-specific polymerase chain reaction (PCR) and a pig-rodent somatic cell hybrid panel were used to map two members of the MyoD gene family. MYOD1 was assigned to pig chromosome 2 and MYF5 to chromosome 5.
Polymer Nanowires with Highly Precise Internal Morphology and Topography (2018)

The construction of precise soft matter nanostructures in solution presents a challenge. A key focus remains on the rational design of functionalities to achieve the high morphological complexity typically found in biological systems. Advances in controlled polymerizations and self-assembly increasingly allow approaches toward complex hierarchical nanomaterials. By combining tailor-made cylindrical polymer brushes, block copolymers and interpolyelectrolyte complexation-driven self-assembly, we demonstrate a facile construction of uniformly compartmentalized and topographically structured polymeric nanowires in aqueous media. The approach offers a modular avenue in programming the internal morphology of polymer nanowires by varying the block copolymer composition and topology.
SOLID PROPELLANT UTILIZATION BY THE BURNING PROPELLANT-COAL AND PROPELLANT-PEAT MIXTURES (1997)

The investigation of the combustion of the mixtures of propellant-coal and propellant-peat for both composite and double-base propellants was performed in a laboratory reactor and in a model industrial bed-burning furnace. The mechanism of combustion of the bricks was studied for various contents (propellant concentration) for the safe and ecologically clean combustion in furnaces. The flammability and explosion limits for the coal-propellant mixtures were determined. It was showed that the energetic advantage and technological possibility of preparation and combustion of bricks made from the propellant-coal and propellant-peat mixtures in the regime of layer combustion.
Science and Technology Text Mining: Mexico Core Competencies (2002)

Abstract : The structure and infrastructure of the Mexican technical literature was determined. A representative database of technical articles was extracted from the Science Citation Index for the year 2002, with each article containing at least one author with a Mexican address. Many different manual and statistical clustering methods were used to identify the structure of the technical literature (especially the science and technology core competencies), and to evaluate the strengths and weaknesses of each technique. One of the pervasive technical topics identified from the clustering, Thin Films research, was analyzed further using bibliometrics, in order to identify the infrastructure of this technology.
