Model Implementation of Lorentzian Spectra for Circuit Noise Simulations in the Frequency Domain

IEEE Journal of the Electron Devices Society, 2022
This work presents a new method for the Verilog-A implementation of Lorentzian noise models, in a module called VERILOR, which can automatically generate either Lorentzian or 1/f-like noise spectra depending on the trap density and gate oxide area, for ...

Approach for Preservation and Reconstruction of Two-Dimensional Wave Spectra and Its Application to Boundary Conditions in Nested Wave Modeling

Remote Sensing, 2023
Typically, storing a two-dimensional wave spectrum could occupy more than one thousand storage units, making saving and reading boundary spectra computationally burdensome in nested wave simulations. This paper proposes a new approach for preservation of

Monte Carlo-based identification of electron and proton edges for calibration of miniaturized tissue equivalent proportional counter

Nuclear Engineering and Technology, 2023
Miniaturized tissue equivalent proportional counters (mini-TEPCs) are proper for radiation dosimetry in medical application because the small size of the dosimeter could prevent pile-up effect under the high intensity of therapeutic beam.

Three-dimensional simulations of turbulent spectra in the local interstellar medium [PDF]

Nonlinear Processes in Geophysics, 2007
Three-dimensional time dependent numerical simulations of compressible magnetohydrodynamic fluids describing super-Alfvénic, supersonic and strongly magnetized space and laboratory plasmas show a nonlinear relaxation towards a state of near ...

Extreme Waves in the Agulhas Current Region Inferred from SAR Wave Spectra and the SWAN Model

Journal of Marine Science and Engineering, 2021
The influence of the Agulhas Current on the wave field is investigated. The study is conducted by performing high resolution spectral wave model simulations with and without ocean currents. The validation of the numerical simulations is performed for the

Witnessing eigenstates for quantum simulation of Hamiltonian spectra [PDF]

Science Advances, 2018
We introduce the concept of an eigenstate witness and use it to find energies of quantum systems with quantum computers.

Molecular Vibrations in Chiral Europium Complexes Revealed by Near‐Infrared Raman Optical Activity

Advanced Science
Raman optical activity (ROA) is commonly measured with green light (532 nm) excitation. At this wavelength, however, Raman scattering of europium complexes is masked by circularly polarized luminescence (CPL).

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...
