Ground states for fractional Kirchhoff equations with critical nonlinearity in low dimension

, 2017
We study the existence of ground states to a nonlinear fractional Kirchhoff equation with an external potential V . Under suitable assumptions on V , using the monotonicity trick and the profile decomposition, we prove the existence of ground states ...

Single‐Step Analog In‐Memory Matrix Computation in Three‐Dimensional Circuits

Advanced Intelligent Systems, EarlyView.
A wooden model illustrates a 3D memristive array designed for single‐step kernel convolutions. It shows how two‐dimensional input data are mapped into the 3D array and convolved in parallel with stored kernels. Color‐coded connection points represent programmed memory‐element values, with each color corresponding to a specific kernel weight.

Numerical Simulation of Electrodialysis Desalination for Multicomponent Salt Lake Brine

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Electrodialysis (ED) technology is presently recognized as an effective approach for extracting lithium from salt lake brine. This study concentrates on modeling the ED desalination process applied to multicomponent salt lake brine and equivalent NaCl solutions.

Maxwell’s True Current

Computation
Maxwell defined a ‘true’ or ‘total’ current in a way not widely used today. He said that “… true electric current … is not the same thing as the current of conduction but that the time-variation of the electric displacement must be taken into account in ...

Engineering Stable Lentiviral Vector Producer Cells Improves LVV Production

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Stable lentiviral vector producer cell lines represent a promising platform for scalable and cost‐efficient vector manufacturing, yet their productivity is often limited by intrinsic host‐cell constraints. In this study, we aimed to identify cellular factors restricting LVV production in stable doxycycline‐inducible GPRTG producer cell lines ...

High-performance calculation of the acoustic backscattering strength based on the Kirchhoff high-frequency approximation

, 2023
The acoustic backscatter strength (target echo strength, TES) of underwater objects, which is important for sonar applications, can be determined by different numerical methods (boundary element method, finite element method, ray tracing and approximate ...

Do Corporate ESG Disclosures Drive Consumer Demand (Sales)? The Role of Environmental Sensitivity

Business Strategy and the Environment, EarlyView.
ABSTRACT The question of whether strong environmental, social, and governance (ESG) disclosure largely benefits high‐demand customers or if it generates value across all sales levels is yet to be empirically verified. This study, therefore, examines how ESG performance influences consumer demand (sales outcomes) among listed firms across African ...

Nanostructured Optical Superabsorbers from Carbon Nanotube Forest for Heat Management Using Environmental Blackbody Radiation from the Visible to Mid‐Infrared

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Our computational model of the optical absorption from multiwalled carbon nanotubes suggests the optical absorption depends strongly on the in‐plane electrical conductivity, and weakly on the through‐plane conductivity. Such strong absorption enables solar‐to‐thermal conversion for heat scavenging in cold climates and radiative cooling in hot climates,

Reduced patella medialization in valgus and varus knees using a KA‐optimized femoral component in kinematically aligned TKA

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellofemoral complications after total knee arthroplasty (TKA) are linked to femoral component design and trochlear alignment. This study compared the effects of a kinematically aligned (KA)‐optimized femoral component versus a standard design on patellofemoral kinematics, contact mechanics and quadriceps function, using native knee ...

The Application of Kirchhoff Approximation in Scattering Calculation

DEStech Transactions on Engineering and Technology Research, 2018
The scattered field of rigid sphere and cylinder are calculated according to Kirchhoff approximation, as well as the stabilization phase method is considered in the calculation. Two cases are included in the results which are monostatic and bistatic.
