Label free ultra-sensitive imaging with sub-diffraction spatial resolution
(IEEE, 2019-07-09)In this paper, we show a new way to break the resolution limit and dramatically improve sensitivity to structural changes. To realize it we developed a novel label free contrast mechanism, based on the spectral encoding ... -
Label-free ultra-sensitive visualization of structure below the diffraction resolution limit
(Wiley, 2018-03-23)For both fundamental study of biological processes and early diagnosis of diseases, information about nanoscale changes in tissue and cell structure is crucial. Nowadays, almost all currently known nanoscopy methods rely ... -
Large acoustoelastic effect
(Elsevier, 2012-03)Classical acoustoelasticity couples small-amplitude elastic wave propagation to an infinitesimal pre-deformation, in order to reveal and evaluate non-destructively third-order elasticity constants. Here, we see that ... -
Large amplitude Love waves
(Oxford Journals, 2008-04-22)In the context of the finite elasticity theory, we consider a model for compressible solids called 'compressible neo-Hookean material'. We show how finite-amplitude inhomogeneous plane wave solutions and finite-amplitude ... -
Late-interseismic state of a continental plate-bounding fault: Petrophysical results from DFDP-1 wireline logging and core analysis, Alpine Fault, New Zealand
(American Geophysical Union (AGU), 2013)We present a geophysical characterization at 0.1-100 m scales of a major plate-bounding continental fault in a late-interseismic state. The Alpine Fault produces M-W approximate to 8 earthquakes every 200-400 years and ... -
LcrG is required for efficient translocation of Yersinia Yop effector proteins into eukaryotic cells
(American Society for Microbiology, 1998-06)Extracellular Yersinia disables the immune system of its host by injecting effector Yop proteins into host cells. We show that a Yersinia enterocolitica nonpolar lcrG mutant is severely impaired in the translocation of ... -
Leaching of decabromodiphenyl ether and hexabromocyclododecane from fabrics under simulated landfill conditions
(KeAi Communications Co. Ltd, 2019-12-30)A series of laboratory experiments were conducted to examine the leaching of decabromodiphenyl ether (BDE-209) and hexabromocyclododecane (HBCDD) from a mix of three fabrics. Consistent with previous reports that such ... -
Learning latent semantic relations from clickthrough data for query suggestion
(2008)For a given query raised by a specific user, the Query Suggestion technique aims to recommend relevant queries which potentially suit the information needs of that user. Due to the complexity of the Web structure and the ... -
Lectin microarray profiling demonstrates equivalent global glycosylation for whey protein ingredients enriched with α-lactalbumin and milk fat globule membrane
(Elsevier, 2022-12-22)Human milk fat globule membrane (MFGM) and whey proteins are nutritionally and functionally valuable, with many beneficial bioactivities associated with their glycosylation. However glycosylation of milk components other ... -
Lectins: getting familiar with translators of the sugar code
(MDPI, 2015-01-22)The view on the significance of the presence of glycans in glycoconjugates is undergoing a paradigmatic change. Initially mostly considered to be rather inert and passive, the concept of the sugar code identifies glycans ... -
Lewis acid induced anomerization of se-glycosides. Application to synthesis of alpha-Se-GalCer
(American Chemical Society, 2016-01-22)The TiCl4 induced anomerization of selenium glycosides of galacturonic acid derivatives is reported. The reaction was successful for galacturonic acid when various alkyl, alkenyl, alkynyl, saccharide, steroid, and lipid ... -
Lewis acid promoted anomerisation of alkyl O- and S-xylo-, arabino- and fucopyranosides
(Elsevier, 2018-11-24)Pentopyranoside and 6-deoxyhexopyranosides, such as those from d-xylose, l-arabinose and l-fucose are components of natural products, oligosaccharides or polysaccharides. Lewis acid promoted anomerisation of some of their ... -
Ligand design for somatostatin receptor isoforms 4 and 5
(Elsevier, 2018-11-17)The somatostatin receptor (SSTR) isoforms, SSTR-4 and SSTR-5 are targets in numerous disorders and diseases. Although there has been some success in achieving selective isoform inhibition, structure-based drug design and ... -
Light driven styrene epoxidation and hydrogen generation using H2O as an oxygen source in a photoelectrosynthesis cell
(Royal Society of Chemistry, 2015-10-02)A dye-sensitized photoelectrosynthesis cell (DSPEC) has been prepared for the oxidation of alkenes to epoxides and evolution of hydrogen using water as an oxygen source and sunlight. A Ru oxidation catalyst, 2,2+ , is ... -
Linking microbial community structure and function during the acidified anaerobic digestion of grass
(Frontiers Media, 2018-03-21)Harvesting valuable bioproducts from various renewable feedstocks is necessary for the critical development of a sustainable bioeconomy. Anaerobic digestion is a well-established technology for the conversion of wastewater ... -
Liquid-crystal-mediated force between a cylindrical nanoparticle and substrate
(American Physical Society, 2007-10-25)Using classical density functional theory, the structure of a molecular fluid around a cylindrical nanoparticle near a solid substrate is studied. The solvent-mediated force between the nanoparticle and the substrate is ... -
Listeria monocytogenes has a functional gamma-aminobutyrate (GABA) shunt: Role in acid tolerance and succinate biosynthesis.
(American Society for Microbiology, 2013)Listeria monocytogenes, the causative agent of human listeriosis, is known for its ability to withstand severe environmental stresses. The glutamate decarboxylase (GAD) system is one of the principal systems utilized by ... -
Low Temperature Fluorescence Studies of Crude Petroleum Oils
(2011)We have studied the low-temperature (133-298 K) fluorescence emission of crude petroleum oils using a combination of steady-state and time-resolved measurements. This was done, first, to see if we could generate linear ... -
