In geostatistics, the design for data collection is central accurate prediction and parameter inference. One important class of geostatistical models log-Gaussian Cox process (LGCP) which used extensively, example, in ecology. However, there are no formal analyses on optimal designs LGCP models. this work, we develop a novel model-based experimental modeling spatiotemporal point data. We propose new spatially balanced rejection sampling directs to locations that priori expected provide most...
Frequency tuning of work modes in the silicon vibratory gyroscope is studied by theoretical, numerical, and experimental methods this paper. First, schematic structure simplified kinematics model were presented for deducing natural frequencies. Then, width length support beams optimized to tune frequencies at their designed value. Besides, frequency difference was experimentally tested manually tuned varying voltage applied on capacitors. The test a prototype showed that could be localized...
Summary Most modern articles in the palaeomagnetism literature are based on statistics developed by Fisher's 1953 paper ‘Dispersion a sphere’, which assumes independent and identically distributed (iid) spherical data. However, palaeomagnetic sample designs usually hierarchical, where specimens collected within sites data then combined across to calculate an overall mean direction for geological formation. The typically more similar than between different sites, so iid assumptions fail. This...
We aimed to study the regional detailed visual outcome and treatment discontinuation of neovascular age-related macular degeneration (nAMD).Clinical records 110 patients treated for nAMD at sole referral centre in Helsinki region were analysed retrospectively. The follow-up was up fourth year.The mean acuity (VA) baseline 56.3 (SD 16.2) letters. last VA first year 59.7 (20.2), corresponding values second, third, years 60.8 (20.6), 60.0 (19.0), (19.3). difference from +3.39 14.6), +3.59...
The adoption of novel molecular strategies such as genomic selection (GS) in crop breeding have been key to maintaining rates genetic gain through increased efficiency and shortening the cycle evaluation relative conventional selection. In search for improved methodologies that incorporate sources variation assessment merit, GS remains a focus research globally. Here we explored role transcriptome data could play enhancing using wheat test case. Across 286 lines, integrated phenotype...
In this work, we consider to improve the model estimation efficiency by aggregating neighbors' information as well identify subgroup membership for each node in network. A tree-based $l_1$ penalty is proposed save computation and communication cost. We design a decentralized generalized alternating direction method of multiplier algorithm solving objective function parallel. The theoretical properties are derived guarantee both consistency convergence. Thorough numerical experiments also...
Abstract. The number of cloud droplets formed at the base depends both on properties aerosol particles and updraft velocity an air parcel base. As spatial scale updrafts is too small to be resolved in global atmospheric models, commonly parameterised based available turbulent kinetic energy. Here we present alternative methods through parameterising high-resolution large eddy simulation (LES) runs case marine stratocumulus clouds. First use our simulations assess accuracy a simple linear...
