ON INJECTIVITY AND P-INJECTIVITY, IV [PDF]

open access: yesBulletin of the Korean Mathematical Society, 2003
[For part I cf. J. Math. Kyoto Univ. 27, 439-452 (1987; Zbl 0655.16012).] A left \(A\)-module \(M\) is called \(p\)-injective if for every principal left ideal \(P\) of \(A\), every \(A\)-homomorphism from \(P\) to \(M\) can be extended to \(A\) to \(M\).

Efficient spin injection into graphene through trilayer hBN tunnel barriers [PDF]

open access: yes, 2018
We characterize the spin injection into bilayer graphene fully encapsulated in hBN using trilayer (3L) hexagonal boron nitride (hBN) tunnel barriers. As a function of the DC bias, the differential spin injection polarization is found to rise up to -60 ...

Frequency and phase modulation performance of an injection-locked CW magnetron. [PDF]

open access: yes, 2006
It is demonstrated that the output of a 2.45-GHz magnetron operated as a current-controlled oscillator through its pushing characteristic can lock to injection signals in times of the order of 100-500 ns depending on injection power, magnetron heater ...

Mid- to long-term success rate and functional outcomes of acromioclavicular injections in patients with acromioclavicular osteoarthritis [PDF]

open access: yesClinics in Shoulder and Elbow, 2023
Background Acromioclavicular (AC) osteoarthritis (OA) is a frequent pathology of the shoulder in elderly patients. Drug injection plays an important role in treatment of AC OA.

Spatially probed electron-electron scattering in a two-dimensional electron gas

open access: yes, 2010
Using scanning gate microscopy (SGM), we probe the scattering between a beam of electrons and a two-dimensional electron gas (2DEG) as a function of the beam's injection energy, and distance from the injection point.

Approximate Injectivity [PDF]

open access: yesApplied Categorical Structures, 2017
In a locally $ $-presentable category, with $ $ a regular cardinal, classes of objects that are injective with respect to a family of morphisms whose domains and codomains are $ $-presentable, are known to be characterized by their closure under products, $ $-directed colimits and $ $-pure subobjects. Replacing the strict commutativity of diagrams

Spin diffusion and injection in semiconductor structures: Electric field effects

open access: yes, 2002
In semiconductor spintronic devices, the semiconductor is usually lightly doped and nondegenerate, and moderate electric fields can dominate the carrier motion. We recently derived a drift-diffusion equation for spin polarization in the semiconductors by

Evolution of Pore Connectivity in the Fushun Oil Shale by Low-Field Nuclear Magnetic Resonance Spectroscopy

open access: yesChinese Journal of Magnetic Resonance, 2019
During in-situ exploitation of the oil shale, the connectivity of the pore structure of the reservoir directly affects not only the flow behavior and heat transfer efficiency of the heat-carrying medium, but also the diffusion and flow behaviors of the ...
