A Relational View of Information Seeking and Learning in Social Networks (2003)

Research in organizational learning has demonstrated processes and occasionally performance implications of acquisition of declarative (know-what) and procedural (know-how) knowledge. However, considerably less attention has been paid to learned characteristics of relationships that affect the decision to seek information from other people. Based on a review of the social network, information processing, and organizational learning literatures, along with the results of a previous qualitative study, we propose a formal model of information seeking in which the probability of seeking information from another person is a function of (1) knowing what that person knows; (2) valuing what that person knows; (3) being able to gain timely access to that person's thinking; and (4) perceiving that seeking information from that person would not be too costly. We also hypothesize that the knowing, access, and cost variables mediate the relationship between physical proximity and information seeking. The model is tested using two separate research sites to provide replication. The results indicate strong support for the model and the mediation hypothesis (with the exception of the cost variable). Implications are drawn for the study of both transactive memory and organizational learning, as well as for management practice.
Semiconductor pixel detector with absorption grid as a tool for charge sharing studies and energy resolution improvement (2011)

A novel approach for characterization of semiconductor pixel detectors using X-rays is presented. A precise gold grid placed in front of the sensor chip segments the incoming X-ray beam into a matrix of precisely defined micro-beams irradiating all pixels in well-defined positions. Analysis of the resulting moiré pattern allows evaluation of the charge sharing effect and determination of its influence on the spectrometric properties of the detector. As opposed to currently used single micro-beam studies realized at synchrotron sources, the whole pixel matrix is investigated at once. This offers a great tool for the investigation of charge sharing phenomena and verification of theoretical models used to describe these detectors. Similarly, such an absorption grid can be used for masking the pixel borders thus suppressing the charge sharing effect. As we demonstrate, this approach significantly improves the spectrometric properties of the pixelated detector at the cost of lower detection efficiency. This technique can be used for energy sensitive X-ray imaging of inanimate objects where the radiation dose does not present an issue.

Protective Effect of Probiotic Bactosac Against Induced Sub Chronic Lead Toxicity in Broiler Chicks (2015)

ABSTRACT:
The protective role of the probiotic Bactosac® in minimizing the negative oxidative stress and the biochemical and morphological alterations induced by sub-chronic exposure of broiler chicks to 2500 ppm lead (pb) acetate in drinking water for 5 consecutive weeks was evaluated. Results revealed that body weight in Pb acetate treated broiler chicks was significantly decreased (47 %). However, the co-administration of Bactosac® with Pb acetate succeeded to improve this percent to 19.62 % in comparison to control group. Also, antioxidants parameters of hepatic and renal tissues were significantly changed in Pb acetate exposed chicks, where the GSH concentration was significantly enhanced, while, GST and CAT activities, were significantly inhibited. Lipid peroxidation indicator MDA was also significantly increased. Activity of hepatic transaminases ALT and AST were significantly elevated in Pb acetate treated chicks while serum creatinine and blood urea showed no significant changes. The accumulation pattern of Pb in treated chicks revealed that the highest and significant concentration was recorded in bone (160 times), then kidneys (13 times), followed by Liver (2.2 times) and brain (1.6), while muscles showed the lowest (1.3 times) accumulation to Pb when compared to control values. Histopathological examination revealed presence of hepatocytic degeneration, necrosis and hemorrhages, as well as, vascular congestion of the inter tubular blood vessels, interstitial mononuclear cell infiltration, glomerular hypercellularity and some areas of inter tubular mononuclear cell infiltrations and aggregations in kidneys of pb-intoxicated birds. Concurrent treatment of Bactosac® with Pb acetate in drinking water of broiler chicks revealed a significant improvement of the previous antioxidant parameters, liver transaminases, accumulation pattern of Pb and morphological alterations. It is concluded that probiotics Bactosac® play an important and promising tool to prevent/reduce pb toxicity in broiler chicks.
Cell-wall polysaccharides and glycoproteins of parenchymatous tissues of runner bean (Phaseolus coccineus) (1990)

1. Polymers were solubilized from the cell walls of parenchyma from mature runner-bean pods with minimum degradation by successive extractions with cyclohexane-trans-1,2-diamine-NNN'N'-tetra-acetate (CDTA), Na2CO3 and KOH to leave the alpha-cellulose residue, which contained cross-linked pectic polysaccharides and Hyp-rich glycoproteins. These were solubilized with chlorite/acetic acid and cellulase. The polymers were fractionated by anion-exchange chromatography, and fractions were subjected to methylation analysis. 2. The pectic polysaccharides differed in their ease of extraction, and a small proportion were highly cross-linked. The bulk of the pectic polysaccharides solubilized by CDTA and Na2CO3 were less branched than those solubilized by KOH. There was good evidence that most of the pectic polysaccharides were not degraded during extraction. 3. The protein-containing fractions included Hyp-rich and Hyp-poor glycoproteins associated with easily extractable pectic polysaccharides, Hyp-rich glycoproteins solubilized with 4M-KOH+borate, the bulk of which were not associated with pectic polysaccharides, and highly cross-linked Hyp-rich glycoproteins. 4. Isodityrosine was not detected, suggesting that it does not have a (major) cross-linking role in these walls. Instead, it is suggested that phenolics, presumably linked to C-5 of 3,5-linked Araf residues of Hyp-rich glycoproteins, serve to cross-link some of the polymers. 5. There were two main types of xyloglucan, with different degrees of branching. The bulk of the less branched xyloglucans were solubilized by more-concentrated alkali. The anomeric configurations of the sugars in one of the highly branched xyloglucans were determined by 13C-n.m.r. spectroscopy. 6. The structural features of the cell-wall polymers and complexes are discussed in relation to the structure of the cell walls of parenchyma tissues.
Isotactic-Specific Polymerization of Propene by aCs-Symmetric Zirconium(IV) Complex Bearing a Dianionic Tridentate [−NNN−] Amidomethylpyrrolidepyridine Ligand (2009)

The synthesis and characterization of a new tridentate amidomethylpyrrolidepyridine ligand (LigH2) and of the corresponding LigZr(NMe2)2 complex (1) are described. Characterization of 1 by single-crystal X-ray diffraction analysis showed a slightly distorted square-pyramidal geometry. Variable-temperature NMR analysis suggested that 1 adopts a Cs-symmetric structure in solution. Complex 1 in combination with AliBu2H and methylalumoxane afforded a highly active single-site catalyst for the polymerization of ethylene and propene, producing ultrahigh molecular weight linear polyethylene and isotactic polypropylene via an “enantiomorphic sites” mechanism of steric control.
Tissue‐specific metabolite profiling of benzylisoquinoline alkaloids in the root of Macleaya cordata by combining laser microdissection with ultra‐high‐performance liquid chromatography/tandem mass spectrometry (2016)

The integrated method is sensitive, specific and reliable for determining trace alkaloids, which is also a powerful tool for metabolite profiling of tissue-specific BIAs in situ. The present findings should contribute to a better understanding of the biosynthesis of BIAs in M. cordata root and provide scientific evidence for its quality evaluation based on morphological characteristics.

Flexible Organic Bistable Devices Based on Graphene Embedded in an Insulating Poly(methyl methacrylate) Polymer Layer (2010)

The electrical properties of flexible nonvolatile organic bistable devices (OBDs) fabricated with graphene sandwiched between two insulating poly(methyl methacrylate) (PMMA) polymer layers were investigated. Current-voltage (I-V) measurements on the Al/PMMA/graphene/PMMA/indium-tin-oxide/poly(ethylene terephthalate) devices at 300 K showed a current bistability due to the existence of the graphene, indicative of charge storage in the graphene. The maximum ON/OFF ratio of the current bistability for the fabricated OBDs was as large as 1 x 10(7), and the endurance number of ON/OFF switchings was 1.5 x 10(5) cycles, and an ON/OFF ratio of 4.4 x 10(6) was maintained for retention times larger than 1 x 10(5) s. No interference effect was observed for the scaled-down OBDs containing a graphene layer. The memory characteristics of the OBDs maintained similar device efficiencies after bending and were stable during repetitive bendings of the OBDs. The mechanisms for these characteristics of the fabricated OBDs are described on the basis of the I-V results.
MRI and cognitive scores complement each other to accurately predict Alzheimer’s dementia 2 to 7 years before clinical onset (2019)

Abstract Background Predicting cognitive decline and the eventual onset of dementia in patients with Mild Cognitive Impairment (MCI) is of high value for patient management and potential cohort enrichment in pharmaceutical trials. We used cognitive scores and MRI biomarkers from a single baseline visit to predict the onset of dementia in an MCI population over a nine-year follow-up period. Method All MCI subjects from ADNI1, ADNI2, and ADNI-GO with available baseline cognitive scores and T1w MRI were included in the study (n=756). We built a Naïve Bayes classifier for every year over a 9-year follow-up period and tested each one with Leave one out cross validation. Results We reached 87% prediction accuracy at five years follow-up with an AUC&gt;0.85 from two to seven years (peaking at 0.92 at five years). Both cognitive test scores and MR biomarkers were needed to make the prognostic models highly sensitive and specific, especially for longer follow-ups. MRI features are more sensitive, while cognitive features bring specificity to the prediction. Conclusion Combining cognitive scores and MR biomarkers yield accurate prediction years before onset of dementia. Such a tool may be helpful in selecting patients that would most benefit from lifestyle changes, and eventually early treatments that would slow cognitive decline and delay the onset of dementia.

Electrical trimming of ion-beam-sputtered polysilicon resistors by high current pulses (1994)

Phosphorus doped polysilicon resistors have been fabricated from microcrystalline silicon films which were deposited by ion beam sputtering using an argon ion beam of diameter 3 cm, energy 1 keV and current density 7mA/cm/sup 2/, with a deposition rate of 100-120 /spl Aring//min. The resistors, having a sheet resistance of 70 /spl Omega//square and a carrier concentration of 7.5/spl times/10/sup 19/ cm/sup -3/, were stressed with current pulses of width 10 /spl mu/s and duty cycle 0.6% for 5 min. There was a steady decrease of resistance with increasing pulse current density above a threshold value 5/spl times/10/sup 5/ A/cm/sup 2/. A maximum fall of 27% was observed for a 95 /spl mu/m long resistor. The current-voltage characteristics were also recorded during the trimming process. The trimming characteristics were simulated using a small-signal resistivity model of Lu et al. (1983). and the I-V characteristics by a large-bias conduction model. A close fitting of the experimental data with the theoretical values needed an adjustment of some grain boundary parameters for the different pulse current densities used for stressing. The nature of variation of the grain boundary parameters indicates that the rapid Joule heating of the grain boundaries due to current pulses passivates the grain boundary interfaces, at lower currents above the threshold, and then, at higher values of currents, causes zone melting and gradual recrystallization of the disordered boundary layers and subsequent dopant segregation. It confirms the mechanism suggested in the physical model of Kato et al. (1982). The role played by the field-enhanced diffusivity and electromigration of dopant ions, due to the high instantaneous temperature of the grain boundaries, has also been discussed. The pulse trimming technique is simple and does not cause damage to the adjacent components on a monolithic chip.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Activities of Noval New Quinolone Compounds against Vancomycin-Resistant Enterococci and Methicillin-Resistant Staphylococcus aureus and Their Synergism with Several Antibiotics. (2003)

The activities of three new quinolone compounds against vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA) and their synergism with several commercially available antibiotics were investigated. Of the three novel new quinolone compounds tested, compound (1) was the most active against VRE and MRSA. Partial synergism was documented between compound (1) and the commercially available antibiotics such as ampicilin (ABPC), gentamicin (GM), minomycin (MINO), fosfomycin (FOM) and vancomycin hydrochloride (VCM) except in the case of ABPC and VCM against MRSA. Timekill analysis for compound (1) and the commercially available antibiotics such as ABPC, GM, MINO, FOM and VCM was performed by using one strain of VRE and one of MRSA. With the increase of the concentration of the added compound (1), the survival bacterial numbers decreased gradually. The above mentioned results suggested that compound (1) could reduce the daily administration dose of the commercially available antibiotics for the cure of nosocomial infection with its partial synergistic effect, and would have the possibility of reducing the occurrence of the nosocomial infections caused by VRE and/or MRSA.
Phenotypic characterization of microbes in the rhizosphere ofalyssum murale (2003)

Metal hyperaccumulator plants like Alyssum murale are used for phytoremediation of Ni contaminated soils. Soil microorganisms are known to play an important role in nutrient acquisition for plants, however, little is known about the rhizosphere microorganisms of hyperaccumulators. Fresh and dry weight, and Ni and Fe concentrations in plant shoots were higher when A. murale was grown in non-sterilized compared to sterilized soils. The analysis of microbial populations in the rhizosphere of A. murale and in bulk soils demonstrated that microbial numbers were affected by the presence of the plant. Significantly higher numbers of culturable actinomycetes, bacteria and fungi were found in the rhizosphere compared to bulk soil. A higher percent of Ni-resistant bacteria were also found in the rhizosphere compared to bulk soil. Percentage of acid producing bacteria was higher among the rhizosphere isolates compared to isolates from bulk soil. However, proportions of siderophore producing and phosphate solubilizing bacteria were not affected by the presence of the plant. We hypothesize that microbes in the rhizosphere of A. murale were capable of reducing soil pH leading to an increase in metal uptake by this hyperaccumulator.
Acceleration of a finite-difference method with general purpose GPUs - Lesson learned (2008)

Modern massively parallel graphics cards (GPGPUs) offer a promise of dramatically reducing computation times of numerically-intensive data-parallel algorithms. As cards that are easily integrated into desktop PCs, they can bring computational power previously reserved for computer clusters to the office space. High performance rates make GPGPUs a very attractive target platform for scientific simulations. In this paper we present the lessons learned during the parallelization of a finite-difference time-domain method, an inherently data-parallel algorithm frequently used for numerical computations, on the state of the art graphics hardware.
Freshman or Fresher? Quantifying the Geographic Variation of Internet Language (2015)

We present a new computational technique to detect and analyze statistically significant geographic variation in language. Our meta-analysis approach captures statistical properties of word usage across geographical regions and uses statistical methods to identify significant changes specific to regions. While previous approaches have primarily focused on lexical variation between regions, our method identifies words that demonstrate semantic and syntactic variation as well. We extend recently developed techniques for neural language models to learn word representations which capture differing semantics across geographical regions. In order to quantify this variation and ensure robust detection of true regional differences, we formulate a null model to determine whether observed changes are statistically significant. Our method is the first such approach to explicitly account for random variation due to chance while detecting regional variation in word meaning. To validate our model, we study and analyze two different massive online data sets: millions of tweets from Twitter spanning not only four different countries but also fifty states, as well as millions of phrases contained in the Google Book Ngrams. Our analysis reveals interesting facets of language change at multiple scales of geographic resolution -- from neighboring states to distant continents. Finally, using our model, we propose a measure of semantic distance between languages. Our analysis of British and American English over a period of 100 years reveals that semantic variation between these dialects is shrinking.
Degradation of Polymers by O(3P) in Low Earth Orbit (2006)

O(3P) is a highly reactive species which may cause damage to materials on contact. In low Earth orbit (LEO) high energy collisions (~4.5 eV) of O(3P) with spacecraft materials can lead to extensive degradation. We use ab initio molecular orbital calculations to investigate the possibility of chain breaking in polyethylene caused by a single O(3P) attack under LEO conditions, since the occurrence of such reactions could greatly accelerate the erosion. The smallest alkanes (N=2,3,5,7) serve as models of polyethylene. For the case of ethane (N=2), we explore the triplet potential energy surface of the following reaction: O(3P)+CH3 CH3 •O CH3+•CH3. Analogous reactions, where O(3P) attacks a central carbon atom, are studied for the higher alkanes. Results obtained using the Hartree-Fock method, and density functional theory are reviewed. We conclude that conditions in LEO are conducive to chain breaking in polyethylene caused by a single O(3P) attack. We also address the question whether the most abundant species in LEO, viz., atomic oxygen in its ground state, O(3P), alone can cause the degradation in fluoropolymer materials. The smallest fluorocarbons CNF2N+2 (N=2,3,5) serve as models of fluoropolymers. Since electronegativity of fluorine seems to preclude Fabstraction by O(3P), we concentrate on direct O(3P) attacks on carbon-carbon bonds. For the case of fluoroethane (N=2), we explore the triplet potential energy surface of the following reaction: O(3P)+CF3 CF3 •O CF3+•CF3. Analogous reactions, where O(3P) attacks a central carbon atom, are studied for the higher fluorocarbons. Results obtained using the Hartree-Fock method and density functional theory are reviewed. We conclude that O(3P) species in LEO possesses enough translational energy to degrade fluorocarbon materials.

OptoFlex: A Flexible, Broadband Parylene Photonic Platform with Integrated Micro-Mirrors for Optical Biointerfaces (2020)

Targeted light delivery into biological tissue is needed in applications such as optogenetic stimulation of the brain, and in vivo functional or structural imaging of tissue. These applications require very compact, soft, and flexible implants that minimize damage to tissue. Here, we demonstrate a novel implantable photonic platform based on a high-density, flexible array of ultracompact (30 ${\mu}$m x 5 ${\mu}$m), low-loss (3.2 dB/cm at ${\lambda}$ = 680 nm, 4.1 dB/cm at ${\lambda}$ = 633 nm, 4.9 dB/cm at ${\lambda}$ = 532 nm, 6.1 dB/cm at ${\lambda}$ = 450 nm) optical waveguides made of biocompatible polymers Parylene C and PDMS. This photonic platform features unique embedded input/output micro-mirrors that redirect light from the waveguides perpendicularly to the surface of the array for localized, patterned illumination in tissue. This architecture enables the design of a fully flexible, compact integrated photonic system for applications such as in vivo chronic optogenetic stimulation of brain activity.

Low Thermal Conductivity YSZ Thermal Barrier Coatings Made by the Solution Precursor Plasma Spray Process (2014)

The vast majority of thermal barrier coatings (TBCs) are made using 7 wt% yttria stabilized zirconia (7YSZ) due to its high thermal expansion coefficient, high fracture toughness, relatively low thermal conductivity and modest use of rare earth elements (Y). Lower thermal conductivity in TBCs is highly desirable because it would allow thinner coatings and/or improved thermal protection. By arranging the porosity in layers using the solution precursor plasma spray (SPPS) process it has been demonstrated that a 7YSZ coating with 15–23% porosity can be reproducibly fabricated having a thermal conductivity of about 0.6W/m·K, approximately half of the thermal conductivity of air plasma spray (APS) TBCs. Preliminary tests show that both cyclic furnace durability and erosion resistance are comparable to APS TBCs.
