Five planets and an independent confirmation of HD 196885Ab from Lick Observatory [PDF]

open access: yes, 2009
We present time series Doppler data from Lick Observatory that reveal the presence of long-period planetary companions orbiting nearby stars. The typical eccentricity of these massive planets are greater than the mean eccentricity of known exoplanets ...

A Levenberg-Marquardt Method for Tensor Approximation

open access: yesSymmetry, 2023
This paper presents a tensor approximation algorithm, based on the Levenberg–Marquardt method for the nonlinear least square problem, to decompose large-scale tensors into the sum of the products of vector groups of a given scale, or to obtain a low-rank tensor approximation without losing too much accuracy.

Comparison methods of short term electrical load forecasting

open access: yesMATEC Web of Conferences, 2018
The supply of electricity that exceeds the load requirement results in the occurrence of electrical power losses. To provide the appropriate power supply to these needs, there must be a plan for the provision of electricity by making prediction or ...

Non-linear optimization of the material constants in Ogden's strain-energy function for incompressible isotropic elastic materials [PDF]

open access: yes, 1981
The Levenberg—Marquardt non—linear least squares optimization algorithm is adapted to compute the material constants in Ogden' s strain—energy function for incompressible isotropic elastic materials. In previous papers, three terms have been included in

Use of Parameter Estimation for Stereolithography Surface Finish Improvement [PDF]

open access: yes, 2005
In order to improve Stereolithography (SLA) surface finish, a systematic approach based on estimation of process parameters is needed. In this paper, the exposure on a desired SLA build surface is formulated as a function of process parameters.

Defect Analysis of the β– to γ–Ga2O3 Phase Transition

open access: yesAdvanced Functional Materials, EarlyView.
The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

Boron‐Doped Nano‐Crystalline Coated Carbon Fibers for Phasic Dopamine Sensing

open access: yesAdvanced Healthcare Materials, EarlyView.
This uniform coating presents a mix of graphitic and diamond‐like carbon to create a mechanically and electrically robust alternative for the electrochemical detection of dopamine. The electrodes in this work possess the equivalent sensitivity to the state‐of‐the‐art FSCV dopamine detecting electrodes, whilst demonstrating an ability to withstand ...

Directed Functionalization of Recombinant Spider Silk Nonwoven Membranes with Antibodies Using Non‐Canonical Amino Acids

open access: yesAdvanced Materials, EarlyView.
A recombinant spider silk protein was functionalized by incorporating genetically encoded bio‐orthogonal reactive azido‐groups. The azido‐functionalized proteins were produced in a scalable biotechnological process, and particles, films, as well as nanofibers were established as anchorage for fully functional antibodies via site‐specific bio‐orthogonal
