Lie Ideal Enhancements of Counting Invariants

open access: yes, 2014
We define enhancements of the quandle counting invariant for knots and links with a finite labeling quandle Q embedded in the quandle of units of a Lie algebra \mathfrak{a} using Lie ideals. We provide examples demonstrating that the enhancement is stronger than the associated unenhanced counting invariant.

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

open access: yesAdvanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Representation of the Ideal Hero’s Environment in Pre-Revolutionary and Soviet Silent Cinema Worldviews [PDF]

open access: yesХудожественная культура
This article focuses on the spaces of large and provincial cities, interiors, and the specifics of frame construction in the context of the relationship between the human and the material. In our analysis, we examined Ya.

Nilpotency and generalized Lie ideals

open access: yesJournal of Algebra, 1989
The authors generalize the notion of inner Lie ideal, defined by \textit{G. M. Benkart} [J. Algebra 43, 561-584 (1976; Zbl 0342.16009)], to that of generalized Lie ideal (GLI), and prove a structure theorem for such objects. For a nonempty subset V of a ring R, set \(V^{(1)}(R)=[V,R]\), and in general, \(V^{(n+1)}(R)=[V,V^{(n)}(R)]\).

Electroactive Metal–Organic Frameworks for Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
Electrocatalysis is crucial in sustainable energy conversion as it enables efficient chemical transformations. The review discusses how metal–organic frameworks can revolutionize this field by offering tailorable structures and active site tunability, enabling efficient and selective electrocatalytic processes.

Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions

open access: yesAdvanced Functional Materials, EarlyView.
Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...

On the structure of Leibniz algebras, whose subalgebras are ideals or core-free

open access: yesДоповiдi Нацiональної академiї наук України
An algebra L over a field F is said to be a Leibniz algebra (more precisely, a left Leibniz algebra), if it satisfies the Leibniz identity: [[a, b], c] = [a, [b, c]] — [b, [a, c]] for all a, b, c ∈ L. Leibniz algebras are generalizations of Lie algebras.

THE CHANGE OF RELIGIOUS UNDERSTANDING FROM IDEAL-RATIONALITY TO PRAGMATIC-MATERIALISTIC

open access: yesEl Harakah, 2017
The study is conducted because of the appearance of many new beliefs in Islam, which has had considerable influence for Indonesian Muslims, regardless the fact that the beliefs have mostly been classified as a cult.
