Categories of Modules with Differentials

Journal of Algebra, 1996
Before the beginning of the theory of Lie algebroids (1967) and later, many algebraic constructions being substantially some generalizations of the Atiyah sequence of a Lie algebroid have appeared, as, for example, Lie pseudoalgebras (Herz), Lie-Cartan pairs (Kastler, Store), Lie-\(d\)-ring (Palais), \((K\)-\(R)\)-Lie algebras (Rinehart), \((K\)-\(A)\)-

IoT System Based on Artificial Intelligence for Hot Spot Detection in Photovoltaic Modules for a Wide Range of Irradiances

Sensors, 2023
Infrared thermography (IRT) is a technique used to diagnose Photovoltaic (PV) installations to detect sub-optimal conditions. The increase of PV installations in smart cities has generated the search for technology that improves the use of IRT, which ...

MC-H-Geo: A Multi-Scale Contextual Hierarchical Framework for Fine-Grained Lithology Classification [PDF]

Sensors
High-resolution lithological mapping of outcrops is fundamental for reservoir characterization and petroleum geology, yet distinguishing lithologies with subtle petrophysical contrasts remains a major challenge.

Nano-engineered thin-film thermoelectric materials enable practical solid-state refrigeration [PDF]

Nature Communications
Refrigeration needs are increasing worldwide with a demand for alternates to bulky poorly scalable vapor compression systems. Here, we demonstrate the first proof of practical solid-state refrigeration, using nano-engineered controlled hierarchically ...

Lasting impact: A co-led community-academic model for a sustainable community-based participatory research training program [PDF]

Journal of Public Health Research
Community-Based Participatory Research (CBPR) is a critical component in building trust and trustworthiness, as well as mitigating power differentials – all of which are essential for building and sustaining community-academic partnerships.

When Is a Graded Free Complex Exact?

Mathematics, 2022
Minimal free resolutions of a finitely generated module over a polynomial ring S=k[x], with variables x={x1,…,xn} and a field k have been extensively studied.

Modulation of Oligodendrocyte Differentiation by Mechanotransduction [PDF]

Frontiers in Cellular Neuroscience, 2016
Oligodendrocytes (OLs) are responsible for the myelination of axons in the central nervous system (CNS). The differentiation of OLs encompasses several stages, through which cells undergo dramatic biochemical and morphological changes. OL differentiation is modulated by soluble factors (SFs)-such as growth factors and hormones-, known to be essential ...

The mappings of degree 1

Abstract and Applied Analysis, 2006
The maps of the form f(x)=∑i=1nai⋅x⋅bi, called 1-degree maps, are introduced and investigated. For noncommutative algebras and modules over them 1-degree maps give an analogy of linear maps and differentials.

Symmetries of Modules of Differential Operators [PDF]

Journal of Nonlinear Mathematical Physics, 2005
Let ${\cal F}\_λ(S^1)$ be the space of tensor densities of degree (or weight) $λ$ on the circle $S^1$. The space ${\cal D}^k\_{λ,μ}(S^1)$ of $k$-th order linear differential operators from ${\cal F}\_λ(S^1)$ to ${\cal F}\_μ(S^1)$ is a natural module over $\mathrm{Diff}(S^1)$, the diffeomorphism group of $S^1$.
