An empirical comparison of ID3 and HONNs for distortion invariant object recognition (2002)

The authors present results of experiments comparing the performance of the ID3 symbolic learning algorithm with a higher-order neural network (HONN) in the distortion invariant object recognition domain. In this domain, the classification algorithm needs to be able to distinguish between two objects regardless of their position in the input field, their in-plane rotation, or their scale. It is shown that HONNs are superior to ID3 with respect to recognition accuracy, whereas, on a sequential machine, ID3 classifies examples faster once trained. A further advantage of HONNs is the small training set required. HONNs can be trained on just one view of each object, whereas ID3 needs an exhaustive training set.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Oxidation of Organotrifluoroborates via Oxone (2010)

A method for the oxidation of organotrifluoroborates using Oxone was developed. A variety of aryl-, heteroaryl-, alkenyl-, and alkyltrifluoroborates were converted into the corresponding oxidized products in excellent yields. This method proved to be tolerant of a broad range of functional groups, and in secondary alkyl substrates it was demonstrated to be completely stereospecific.
Hplc analysis of phenolic acids in mountain germander (Teucrium montanum L) extracts (2004)

The methanol, petroleum ether, chloroform, ethyl acetate, 1-butanol and water extracts were obtained by extraction of mountain germander (Teucrium montanum L). The total phenolic content in extracts was measured by Folin-Ciocalteu method. The 1-butanol extract had the highest phenolic content (296.00 mg/g). High performance liquid chromatography (HPLC) was employed to define qualitative and quantitative content of phenolic acids in mountain germander extracts. The largest number of phenolic acids were determined in ethyl acetate and 1-butanol extracts, while these acids were not present in petroleum ether extract. The highest content of phenolic acids (28.619 mg/g) had ethyl acetate extract and gentisic acid (14.432 mg/g) was its major component. Despite of a large number of phenolic acids in 1-butanol extract their content was only 3.740 mg/g.
Towards an access control system for mobile peer-to-peer collaborative environments (2003)

Access control is one of the key requirements in enterprise security. A number of approaches in distributed systems have been designed that support various (new) paradigms such as peer-to-peer, nomadic working, and team working. Few of them, however, explicitly take into account the possible superposition of these concepts. Such a superposition often results in conflicting and additional requirements. We present ongoing work in developing an access control system for peer-to-peer mobile teamwork environments. This system is developed as part of the MOTION project. The goal of this project is to develop a service architecture for mobile teamwork, providing support for various devices and taking into account diverse connectivity modes. We present the requirements for an access control system that simultaneously supports mobility, collaboration, and peer-to-peer, illustrate our solution, and discuss how it meets the requirements.
Direct Exchange of a Ketone Methyl or Aryl Group to Another Aryl Group through CC Bond Activation Assisted by Rhodium Chelation (2012)

Swapped: Commercially available quinolinone derivatives (1 or 2, see scheme) were reacted with arylboronic acids in the presence of a RhI complex to give aryl(quinolin-8-yl)methanone products 3 in medium to good yields. A mechanism that involves the in situ oxidation of RhI to RhIII by O2 in the presence of CuI was proposed.
Improved CVD aluminum deposition using in-situ sputtered nucleation layers (2002)

Superior-quality chemical vapor deposited (CVD) Al films have been achieved using tri-isobutylaluminum (TIBA) on in-situ sputtered nucleation layers. The nucleation layer enhances the growth of CVD Al, resulting in smooth, high-quality films suitable for VLSI application. The use of in-situ sputtered seed layers allows the deposition of CVD Al on SiO/sub 2/ without having to expose the wafers to TiCl/sub 4/, which may leave Cl residue and cause corrosion. In addition, the CVD films deposited on a TiN seed layer demonstrate smooth morphology and high conductivity and show no presence of the pinholes or interfacial voids which rendered earlier CVD Al films unusable for VLSI. The TIBA process is done at low temperature of 250 degrees C, and TiN is an accepted barrier metal. The combined TiN/CVD Al process promises a low-cost, high-quality manufacturable process for VLSI metallization.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

The Influence of Matrix Degradation and Functionality on Cell Survival and Morphogenesis in<scp>PEG</scp>‐<scp>B</scp>ased Hydrogels (2013)

Two norbornene-functionalized PEG macromers are synthesized to render hydrogels with different hydrolytic degradability. Dithiol-containing linkers such as dithiothreitol or biscysteine-containing peptides are used to control proteolytic degradability. The influence of thiol-ene gel degradability on cell survival and morphogenesis in 3D is assessed using hMSCs and pancreatic MIN6 β cells. The initial cell viability can be negatively affected in highly crosslinked thiol-ene hydrogels. When cells are encapsulated in thiol-ene gels lacking cell-adhesive motifs, their survival and proliferation are promoted in more hydrolytically labile hydrogels. The degree of 3D cell spreading in encapsulated hMSCs is enhanced when the matrices are immobilized with cell-adhesive motifs.
Bioactive Terpenoids from Octocorallia. 3. A New Eunicellin-Based Diterpenoid from the Soft Coral <i>Cladiella sphaeroides</i> (1997)

A new diterpenoid, cladiellaperoxide (2), has been isolated from the soft coral Cladiella sphaeroides, together with the known diterpenoid cladiellisin (1). Their structures were characterized by NMR studies and chemical conversion. The absolute configurations of 1 and 2 have been elucidated by the modified Mosher method. Compound 2 showed lethality toward brine shrimp.
A performance test to monitor rehabilitation and evaluate anterior cruciate ligament injuries (1986)

A performance test simulating components of sports was devised to evaluate dysfunction after ACL injury. The test included a one-leg hop, running in a figure of eight (straight running and turn running measured separately), running up and down a spiral staircase, and running up and down a slope. Twenty-six men with ACL injury, most of them soccer players, and 66 uninjured male soccer players were studied. Patients with ACL injury performed significantly less well than the uninjured players. Test items of special interest were turn running in the figure of eight, stair running, and slope running, all of which place high demand on the knee. It is concluded that a performance test of this design is useful for monitoring rehabilitation and for evaluating the patient's condition. Before sports can be resumed at the original level, normal strength and normal performance should be regained.
Effects of divalent cations on adhesiveness of rat polymorphonuclear neutrophils <i>In vitro</i> (1968)

Abstract Cell preparations rich in polymorphonuclear neutrophils (PMN) were obtained from peritoneal exudates of rats without the use of any anticoagulant. The adhesiveness of these PMN to glass bead columns coated with rat serum were studied quantitatively using suspending solutions free of added serum protein. A dependence of the PMN adhesiveness upon divalent cations was demonstrated. Added singly Mg 2+ , Ni 2+ , Zn 2+ , Co 2+ , Mn 2+ , Cu 2+ , or Cd 2+ were found to be effective whereas Ca 2+ , Sr 2+ and Ba 2+ were ineffective. A possible auxilliary role for Ca 2+ when added with Mg 2+ is suggested by the data. The ineffectiveness of the ions Ca 2+ , Sr 2+ and Ba 2+ was shown by use of an ion electrode not to be due to the unavailability of the ionized species. Procedures are described for obtaining highly reproducible results with the Orion Divalent Cation Electrode. The ineffectiveness of the ions Ca 2+ , Sr 2+ and Ba 2+ were also shown not to be due to action as general protoplasmic poisons. The effective ions are distinguished from the ineffective ones by characteristic ranges of ionic radii, coordination number, second ionization potentials, electronegativities and affinity constants. Removal of components of complement from the cells by washing in 0.05 M EDTA, and heating all serum used for 30 minutes at 56°C had no significant effect on the adhesiveness of the PMN. A role for complement, therefore appears largely excluded.
Glomerular epithelial detachment, not reduced charge density, correlates with proteinuria in adriamycin and puromycin nephrosis. (1989)

To identify the structural change coincident with increased glomerular permeability in both adriamycin (ADR) and puromycin-aminonucleoside (PAN) nephrosis, we explored the temporal correlation between developing proteinuria, the reduction in glomerular polyanions, and the detachment of epithelium from glomerular basement membrane (GBM). Sprague-Dawley rats received a single tail-vein injection of PAN (150 mg/kg), ADR (7.5 mg/kg) or saline. Nephrotic-range proteinuria appeared between days 2 to 5 in the PAN-treated and days 5 to 10 in the ADR-treated rats. The GBM heparan sulfate charge density and epithelial membrane sialic acid (SA) content were determined before, during and after the rise in proteinuria. Polyethyleneimine was used to detect heparan sulfate and the number staining of renal cortical slices was used to detect heparin sulfate and the number of sites/microns GBM in the lamina rara externa were counted on electron micrographs (magnification x60,000). Controls had a regular distribution of polyethyleneimine 20.19 +/- 1.72 sites/microns (X + SD). In ADR rats, the polyethyleneimine density decreased by day 5, 18.61 +/- 1.79 sites/microns (p less than 0.05) which persisted to day 15, 17.38 +/- 1.27 sites/microns (p less than 0.02). PAN rats, by day 1, had significant reduction, 14.94 +/- 1.47 sites/microns (p less than 0.05), which persisted to day 20. The total membrane-bound SA content of isolated glomeruli was analyzed with a modified Warren's method. The SA content in control glomeruli was 46.8 +/- 8.0 nmol/mg glomerular protein (X +/- SD). In ADR rats, there was significant decrease in SA content to 84 +/- 3% of control (p less than 0.01) at day 15. In PAN rats, by day 2, the SA content was decreased to 73 +/- 18% of control (p less than 0.05). In both models, scanning and transmission electron microscopy revealed epithelial foot process fusion, loss of slit diaphragms, and vacuolization before increased proteinuria. Epithelial detachment from the GBM and rupture of vacuoles occurred coincidently with rapid development of nephrotic proteinuria in both models. In summary, reduced GBM heparan sulfate and epithelial SA content do not correlate with the onset of altered glomerular permeability, whereas epithelial detachment is coincident with the development of massive proteinuria in both ADR and PAN nephrosis.
Sonochemical Degradation Kinetics of Methyl Violet in Aqueous Solutions (2003)

The sonochemical degradation in aqueous solution of methyl violet, chosen as a model of a basic dye, was studied. The ultrasonic degradation kinetics in water were found to be first-order and the degradation rate coefficient is 1.35×10-2 min-1 (R= 0.9934, n=8) at 20±1°C. The influence of the initial concentrations, reaction temperature and the pH of medium on the ultrasonic decomposition of methyl violet were also investigated.
Structural and rheological evolution of silica nanoparticle gels (2010)

The gelation dynamics of a sol of colloidal silica of approximately 7 nm radius particles is studied using a combination of light scattering and rheometry. By changing the ionic strength (by addition of a salt solution resulting in different ultimate molarities) of the mixture, a stable sol can be destabilized, leading to aggregation and later gelation. The gel time tgel can be varied from hours to weeks, indicating a reaction-limited aggregation process. Static light scattering is used to extract the fractal dimension Df of the aggregates, which is found to be approximately 2. The evolution of cluster size is probed by dynamic light scattering, and follows an exponential growth. Rheometry is used to assess the gelation time and further development of the network strength after gelation. The elastic modulus (G′) is found to scale as G′ ∼ ϕ3.3, where ϕ is the silica particle volume fraction. It was observed that the gel time (after salt solution addition) depends on both the particle volume fraction and salt concentration, showing a divergence at low volume fraction or low salt concentration. For a single solid fraction, data for the cluster hydrodynamic radius, normalized by the single particle radius, from experiments with a wide range of gel times can be collapsed onto a master curve when the time after the salt addition, t, is scaled as t/tgel; a similar collapse of viscosity and the linear viscoelastic data after gelation can be obtained using the same scaling of time. Salt concentration affects the gel time but not the strength of the gel network, thus allowing very accurate prediction of network formation times and mechanical properties.
Double Resource Allocation Handover for Vehicular Device-to-Device Communication (2018)

The mobility management and resource allocation are key technologies in Long Term Evolution-Vehicle (LTE-V). To improve the Double Resource Allocation Handover (DRAH) scheme, a mobility management method for vehicles in multicell environment, author propose dynamic parameter DRAH scheme to improve the system performance and efficiency of resource utilization. The SUMO and Omnet are used to build the traffic network and cellular network for the simulation. And the simulation in the virtual environment proves that this scheme could well support V2X communication and the performance is much better than the DRAH scheme.
Nuclear signaling by the APP intracellular domain occurs predominantly through the amyloidogenic processing pathway (2009)

Proteolytic processing of the amyloid precursor protein (APP) occurs via two alternative pathways, localized to different subcellular compartments, which result in functionally distinct outcomes. Cleavage by a beta-gamma sequence generates the Abeta peptide that plays a central role in Alzheimer's disease. In the case of alpha-gamma cleavage, a secreted neurotrophic molecule is generated and the Abeta peptide cleaved and destroyed. In both cases, a cytosolic APP intracellular domain (AICD) is generated. We have previously shown that coexpression of APP with the APP-binding protein Fe65 and the histone acetyltransferase Tip60 results in the formation of nuclear complexes (termed AFT complexes), which localize to transcription sites. We now show that blocking endocytosis or the pharmacological or genetic inhibition of the endosomal beta-cleavage pathway reduces translocation of AICD to these nuclear AFT complexes. AICD signaling further depends on active transport along microtubules and can be modulated by interference with both anterograde and retrograde transport systems. Nuclear signaling by endogenous AICD in primary neurons could similarly be blocked by inhibiting beta-cleavage but not by alpha-cleavage inhibition. This suggests that amyloidogenic cleavage, despite representing the minor cleavage pathway of APP, is predominantly responsible for AICD-mediated nuclear signaling.
Prevalence of childhood asthma in Istanbul, Turkey (1997)

In order to determine the asthma prevalence in 6-12-year-old schoolchildren in Istanbul, we issued 2350 questionnaires, according to ISAAC criteria, in six randomly selected city primary schools to be completed at home by parents. A total of 2232 of the questionnaires were completed, an overall response rate of 94.9%, and 2216 questionnaires were taken into consideration. The prevalence of asthma was found to be 9.8% and wheezing 15.1%. To investigate the effect of socioeconomic status on the prevalence of asthma, we evaluated the heating system at home, the place of residence, the educational levels of the mother and father, the number of people living in the house, the sharing of bedrooms, and the annual family income. In conclusion, the prevalence of childhood asthma was not affected by any of these factors. Atopic family history, food allergy, eczema, and frequent otitis media and sinusitis attacks were evaluated and found to be significant in asthma prevalence.
Image Retrieval with Fisher Vectors of Binary Features (2013)

Recently, the Fisher vector representation of local features has attracted much attention because of its effectiveness in both image classification and image retrieval. Another trend in the area of image retrieval is the use of binary feature such as ORB, FREAK, and BRISK. Considering the significant performance improvement in terms of accuracy in both image classification and retrieval by the Fisher vector of continuous feature descriptors, if the Fisher vector were also to be applied to binary features, we would receive the same benefits in binary feature based image retrieval and classification. In this paper, we derive the closed-form approximation of the Fisher vector of binary features which are modeled by the Bernoulli mixture model. In experiments, it is shown that the Fisher vector representation improves the accuracy of image retrieval by 25% compared with a bag of binary words approach.
Vowel Length And Vowel Quality In Khasi (1967)

One of the most striking phonetic characteristics of languages of the Austroasiatic family such as Mon, Khmer, and Vietnamese is the great variety of vowel qualities that appear to be kept apart by native speakers despite the fact that some of them differ from each other so slightly that it is hard for the foreign observer to believe that they can be functionally distinct in practice. Accompanying these minute quality distinctions there are frequently puzzling and seemingly non-systematic variations in the length of vowels and in their distribution.
The volume change on ionizatin of weak electrolytes (1954)

The standard partial molar volumes of some strong and weak electrolytes have been measured in water and three other solvents. The results have been used to estimate the volume changes which accompany the ionization of weak electrolytes. Solvent effects are discussed.
An optically driven quantum dot quantum computer (2003)

We propose a design for a quantum computer that builds on n-type SET structures reported by Tarucha et al. (1996). Our design consists of an array of free standing pillars with source and drain electrodes at the top and bottom of the pillar and a stacked series of asymmetric GaAs/AlGaAs quantum wells arrayed along the axis. By applying a negative bias to the cylindrical gate electrode, carriers near the surface are depleted. The parabolic electrostatic potential provides confinement in the radial direction while bandgap discontinuities in the quantum wells provide confinement along the pillar axis. In operating as a quantum computer the source and drain are grounded and the number of electrons in each dot are set to one by adjusting the gate voltage. Qubits are encoded in the ground state and first excited state of the quantum dot electrons. The pillar array constitutes an ensemble of quantum computers that operate simultaneously.
Generation of multi-photon entangled states with integrated optical frequency comb sources (2016)

We demonstrate that four-photon entangled qubit states can be generated from an optical frequency combs source. This state generation is evidenced by four-photon quantum interference, and quantum state tomography reveals a fidelity above 64%.
