Current Transport Mechanism for Heavy-Ion Degraded SiC MOSFETs
(Institute of Electrical and Electronics Engineers, 2019)
High sensitivity of SiC power MOSFETs has been
observed under heavy ion irradiation, leading to permanent
increase of drain and gate leakage currents. Electrical postirradiation analysis confirmed the degradation of the ...
Curve packing and modulus estimates
(American Mathematical Society, 2018)
A family of planar curves is called a Moser family if it contains an isometric
copy of every rectifiable curve in R
2
of length one. The classical "worm problem" of L.
Moser from 1966 asks for the least area covered ...
Curvelet-based method for orientation estimation of particles from optical images
(S P I E - International Society for Optical Engineering, 2014)
A method based on the curvelet transform is introduced to estimate the orientation distribution from
two-dimensional images of small anisotropic particles. Orientation of fibers in paper is considered as a particular
application ...
Curvewise characterizations of minimal upper gradients and the construction of a Sobolev differential
(Mathematical Sciences Publishers, 2024)
We represent minimal upper gradients of Newtonian functions, in the range 1≤p<∞, by maximal directional derivatives along “generic” curves passing through a given point, using plan-modulus duality and disintegration ...
Cutting rules and positivity in finite temperature many-body theory
(IOP Publishing, 2022)
For a given diagrammatic approximation in many-body perturbation theory it is not guaranteed that positive observables, such as the density or the spectral function, retain their positivity. For zero-temperature systems ...
Cyanobacteria and Their Metabolites in Mono- and Polidominant Shallow Eutrophic Temperate Lakes
(MDPI, 2022)
Monodominant (one species dominates) or polidominant (multiple species dominate) cyanobacterial blooms are pronounced in productive freshwater ecosystems and pose a potential threat to the biota due to the synthesis of ...
Cyclic Sulfoximine and Sulfonimidamide Derivatives by Copper‐Catalyzed Cross‐Coupling Reactions with Elemental Sulfur
(Wiley, 2023)
Copper-catalyzed cross-coupling reactions of α-bromoaryl NH-sulfoximines with elemental sulfur lead to benzo[d][1,3,2]dithiazole-1-oxides, which represent a new class of three-dimensional heterocycles. The reactions proceed ...
Cyclical and stochastic thermal variability affects survival and growth in brook trout
(Pergamon Press, 2019)
Directional changes in temperature have well-documented effects on ectotherms, yet few studies have explored how increased thermal variability (a concomitant of climate change) might affect individual fitness. Using a ...
Cyclotron instability in the afterglow mode of minimum-B ECRIS
(American Institute of Physics, 2016)
It was shown recently that cyclotron instability in non-equilibrium plasma of a minimum-B electron
cyclotron resonance ion source (ECRIS) causes perturbation of the extracted ion current and generation
of strong bursts ...
Cytoplasmic parvovirus capsids recruit importin beta for nuclear delivery
(American Society for Microbiology, 2020)
Parvoviruses are an important platform for gene and cancer therapy. Their cell entry and the following steps including nuclear import are inefficient limiting their use in therapeutic applications. Two models exist on ...
