Microphysical particle parameters from extinction and backscatter lidar data by inversion with regularization: theory
(1999-04-20)A method is proposed that permits one to retrieve physical parameters of tropospheric particle size distributions, e.g., effective radius, volume, surface-area, and number concentrations, as well as the mean complex ... -
Microphysical particle properties derived from inversion algorithms developed in the framework of EARLINET
(2016-10-12)We present a summary on the current status of two inversion algorithms that are used in EARLINET for the inversion of data collected with EARLINET multiwavelength Raman lidars. These instruments measure backscatter coecients ... -
Micropower Generation using Buckling Piezoelectric Elements
(2021-08-05)In recent years, piezoelectric materials and structures have gained significant attention for energy harvesting purposes. This attention can be attributed to the enhancement of low-power electronics and the high energy ... -
Microquasars : What do radio and X-ray observations tell us?
(2006-12-01)Microquasars, or X-ray binaries exhibiting radio jets, have been observed extensively at all wavelengths for the past decade or so. Primarily, they have been observed in the X-ray regimes and the radio. In this paper we ... -
MicroRNA expression profiles in pediatric dysembryoplastic neuroepithelial tumors.
(2016-01-30)Among noncoding RNAs, microRNAs (miRNAs) have been most extensively studied, and their biology has repeatedly been proven critical for central nervous system pathological conditions. The diagnostic value of several miRNAs ... -
MicroRNAs Regulate Ca 2+ Homeostasis in Murine Embryonic Stem Cells
(2023-07-28)MicroRNAs (miRNAs) are important regulators of embryonic stem cell (ESC) biology, and their study has identified key regulatory mechanisms. To find novel pathways regulated by miRNAs in ESCs, we undertook a bioinformatics ... -
Microstructural insight into inhalation powder blends through correlative multi-scale X-ray Computed Tomography
(2023-10-30)Dry powder inhalers (DPI) are important for topical drug delivery to the lungs, but characterising the pre-aerosolised powder microstructure is a key initial step in understanding the post-aerosolised blend performance. ... -
Microstructure Characterization and Battery Performance Comparison of MOF-235 and TiO 2 -P25 Materials
(2022-01-21)The growing interest in energy storage has led to the urgent need for the development of high-performance cathode electrodes. The commercialized materials MOF-235 and TiO2-P25 exhibit characteristics that may be suitable ... -
Microtubule dynamic instability: numerical simulation of microtubule transition properties using a Lateral Cap model
(1990)We present a numerical formulation for the dynamic instability of microtubules involving the stabilisation of growing microtubules by a single layer of tubulin-GTP, with GTP hydrolysis effectively coupled to tubulin-GTP ... -
Microvesicles and epithelial mesenchymal transition in the development of cancer
(2012-09-13)Microvesicles released by tumour cell lines are thought to play an important role in both extracellular matrix (ECM) invasion and evasion of the immune system. We have examined the role of MVs derived from a T cell line ... -
Microvesicles released constitutively from prostate cancer cells differ biochemically and functionally to stimulated microvesicles released through sublytic C5b-9
(2015-05-08)We have classified microvesicles into two subtypes: larger MVs released upon stimulation of prostate cancer cells, sMVs, and smaller cMVs, released constitutively. cMVs are released as part of cell metabolism and sMVs, ... -
Microvesicles released from Giardia intestinalis disturb host-pathogen response in vitro
(2017-03-31)Giardia intestinalis (G.I), is an anaerobic protozoan and the aetiological agent of giardiasis, a diarrhoea present worldwide and associated with poverty. G.I has a simple life cycle alternating between cyst and trophozoite. ... -
The mid-infrared environments of 6.7 GHz methanol masers from the Methanol Multi-Beam Survey
(2013-04-01)We present a study of the mid-infrared environments and association with star formation tracers of 6.7 GHz methanol masers taken from the Methanol Multi-Beam (MMB) survey. Our ultimate goal is to establish the mass of the ... -
A mid-infrared imaging catalogue of post-asymptotic giant branch stars
(2011-10-01)Post-asymptotic giant branch (post-AGB) stars are key objects for the study of the dramatic morphological changes of low- to intermediate-mass stars on their evolution from the AGB towards the planetary nebula stage. There ... -
Mid-infrared imaging of the dust shell around the post-asymptotic giant branch star HD 161796
(2003)We present mid-infrared (IR) images of HD 161796 (IRAS 17436+5003), taken with the OSCIR imager on the Gemini North Telescope, that resolve for the first time the thermal emission structure of the dust shell around this ... -
Mid-infrared photometry of cold brown dwarfs : diversity in age, mass and metallicity
(2010)We present new Spitzer Infrared Array Camera (IRAC) photometry of 12 very late-type T dwarfs: nine have [3.6], [4.5], [5.8], and [8.0] photometry and three have [3.6] and [4.5] photometry only. Combining this with previously ...
