A Morse theoretic description of the Goresky-Hingston product

, 2018
The Goresky-Hingston coproduct was first introduced by D. Sullivan and later extended by M. Goresky and N. Hingston. In this article we give a Morse theoretic description of the coproduct.

Homotopy BV-algebra structure on the double cobar construction [PDF]

, 2014
We show that the double cobar construction, $\Omega^2 C_*(X)$, of a simplicial set $X$ is a homotopy BV-algebra if $X$ is a double suspension, or if $X$ is 2-reduced and the coefficient ring contains the ring of rational numbers $\mathbb{Q}$. Indeed, the

Differential Geometry of the q-plane

, 2001
Hopf algebra structure on the differential algebra of the extended $q$-plane is defined. An algebra of forms which is obtained from the generators of the extended $q$-plane is introduced and its Hopf algebra structure is given.Comment: 9 ...

Have the environmental benefits of insect farming been overstated? A critical review

Biological Reviews, Volume 101, Issue 1, Page 163-194, February 2026.
ABSTRACT Insect farming is frequently promoted as a sustainable food solution, yet current evidence challenges many environmental benefits claimed by industry proponents. This review critically examines the scientific foundation for assessing the environmental impacts of insect farming in both human food and animal feed applications.

Loop coproducts

, 2009
In this paper we show that if $A$ is a Poisson algebra equipped with a set of maps $ ^{(i)}_\la:A \to A^{\otimes N}$ satisfying suitable conditions, then the images of the Casimir functions of $A$ under the maps $ ^{(i)}_\la$ (that we call "loop coproducts") are in involution.

Seeing Through the “FOG” of U.S. Feedstock Incentives for Transportation Fuels

GCB Bioenergy, Volume 18, Issue 2, February 2026.
ABSTRACT The demand for fats, oils, and greases (FOG) as biofuel feedstocks has increased in recent years. Further expansions will have uncertain, but potentially significant, effects on food prices, greenhouse gas emissions, and the U.S. farm economy. To address the market‐mediated effects of expanding FOG feedstock consumption, U.S.

Fiber composition of 190 novel energy cane genotypes and their potential for biorefinery applications

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 253-267, January/February 2026.
Abstract Energy cane has emerged as a promising feedstock for biorefineries due to its high fiber yield and potential for diversified bioproducts. This study evaluated the fiber composition of 190 energy cane genotypes and assessed their theoretical potential for producing second‐generation (2G) ethanol, polyethylene, and xylitol.

Modules Over Coproducts of Rings [PDF]

Transactions of the American Mathematical Society, 1974
Let Ro be a skew field, or more generally, a finite product of full matrix rings over skew fields. Let (RX)XEA be a family of faithful Rorings (associative unitary rings containing RO) and let R denote the coproduct ("free product") of the RX as R0-rings. An easy way to obtain an R-module M is to choose for each X E A U {0} an Rx-module Mx, and put M =

Twist maps for non-standard quantum algebras and discrete Schrodinger symmetries

, 2000
The minimal twist map introduced by B. Abdesselam, A. Chakrabarti, R. Chakrabarti and J. Segar (Mod. Phys. Lett. A 14 (1999) 765) for the non-standard (Jordanian) quantum sl(2,R) algebra is used to construct the twist maps for two different non-standard ...

Investigation Into the Role of Reductants and Cosubstrates in Lytic Polysaccharide Monooxygenase Thermothielavioides terrestris AA9E Binding to Cellulose by Single‐Molecule Imaging

Biotechnology and Bioengineering, Volume 123, Issue 1, Page 52-63, January 2026.
In glucose oxidase + catalase (GODCAT) and protocatechuic acid/protocatechuate 3,4‐dioxygenase (PCA/PCD) oxygen‐scavenging buffers, some Cy5‐TtAA9E bound to crystalline cellulose fibrils. Adding ascorbic acid (AscA) vastly increased enzyme binding to cellulose in the GODCAT buffer but diminished enzyme binding to cellulose in the PCA/PCD buffer ...
