A method of constructing phyllotaxically arranged modular models by partitioning the interior of a cylinder or a cone

open access: yesMachine Graphics & Vision, 2014
Illumination correction is a method used for removing the influence of light coming from the environment and of other distorting factors in the image capturing process.

Flexible Wide Bandgap Electrode System for In situ Cell Sensing and Irreversible Electroporation

open access: yesAdvanced Materials Interfaces, EarlyView.
The paper reports the design and wafer‐level microfabrication of a long‐lived, flexible 3C‐SiC electrode capable of sensitive and in situ cell sensing, as well as electroporation ablation. The work demonstrates a biocompatible and durable electrode platform that can perform reliable electrical interfacing with biological tissues over extended periods ...

On odd powers of nonnegative polynomials that are not sums of squares

open access: yesForum of Mathematics, Sigma
We initiate a systematic study of nonnegative polynomials P such that $P^k$ is not a sum of squares for any odd $k\geq 1$ , calling such P stubborn. We develop a new invariant of a real isolated zero of a nonnegative polynomial in the plane,

Nanoporous Silica Embedded in Nanoporous Platinum: A Versatile Composite Coating for Implant‐Associated Drug Delivery From Neuronal Electrodes

open access: yesAdvanced Materials Technologies, EarlyView.
Nanoporous silica nanoparticles incorporated in nanoporous platinum offer the possibility for implant‐associated drug delivery from neuronal electrodes. ABSTRACT Sensorineural hearing loss, resulting from damage to the hair cells of the inner ear, profoundly impairs quality of life.

Computation of limit and shakedown using the NS-FEM and second-order cone programming

open access: yesHo Chi Minh City Open University Journal of Science - Engineering and Technology, 2012
This paper presents a novel numerical procedure for computation of limit and shakedown using node-based smoothed finite element method (NS-FEM) in combination with second-order cone programming (SOCP). The obtained discretization formulation is then cast

On a multivalued second order differential problem with Hukuhara derivative [PDF]

open access: yesOpuscula Mathematica, 2008
Let \(K\) be a closed convex cone with the nonempty interior in a real Banach space and let \(cc(K)\) denote the family of all nonempty convex compact subsets of \(K\). Assume that continuous linear multifunctions \(H,\Psi : K \to cc(K)\) are given.

Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

open access: yesAdvanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Numerical Simulation of Induced Cone-shaped Area in Agitated Tank Bottom Based on FLUENT

open access: yesShiyou jixie, 2016
To address the low fluid flow rate in the recirculation zone in the glass-lined agitated tank bottom that is likely to cause accumulation of materials and hamper the mixing, the flow field of the recirculation zone in the glass-lined agitated tank bottom

Shock timing on the National Ignition Facility: First experiments

open access: yesEPJ Web of Conferences, 2013
An experimental campaign to tune the initial shock compression sequence of capsule implosions on the National Ignition Facility (NIF) was initiated in late 2010. The experiments use a NIF ignition-scale hohlraum and capsule that employs a re-entrant cone
