Brauer groups of Quot schemes [PDF]

Michigan Mathematical Journal, 2015
Let $X$ be an irreducible smooth complex projective curve. Let ${\mathcal Q}(r,d)$ be the Quot scheme parametrizing all coherent subsheaves of ${\mathcal O}^{\oplus r}_X$ of rank $r$ and degree $-d$. There are natural morphisms ${\mathcal Q}(r,d) \longrightarrow \text{Sym}^d(X)$ and $\text{Sym}^d(X) \longrightarrow \text{Pic}^d(X)$.

Ketogenic Diet Alleviates Colorectal Cancer by Attenuating Macrophage M2 Polarisation Triggered by Oncometabolite MMA Derived From the Gut Microbiota

Cell Proliferation, EarlyView.
Proposed mechanism of the ketogenic diet‐microbiota‐MMA‐immune axis in CRC. (Part 1) A ketogenic diet remodels gut microbiota homeostasis by depleting MMA‐producing bacteria, thereby reducing the accumulation of the oncometabolite (MMA). (Part 2) At the molecular level, MMA acts as a ligand that binds to Rap1, activating the downstream MAPK/ERK ...

Dentine Regeneration With Calcium Strontium Silicate: In Vitro Odontogenic Differentiation, Antimicrobial Activity, Immunomodulation and In Vivo Pulpotomy in Rat Molars

International Endodontic Journal, EarlyView.
ABSTRACT Aim This study examined the in vitro and in vivo performance of calcium strontium silicate (CSR) as a novel biomaterial for vital pulp therapy (VPT), assessing its odontogenic differentiation, antibacterial activity, immunomodulation, inflammatory response and dentine regeneration potential compared to calcium silicate (CS) and Mineral ...

The Brauer Group of a Closed Category [PDF]

Proceedings of the American Mathematical Society, 1975
The Brauer group of a finitely bicomplete closed category is defined. This group gives known Brauer groups for the appropriate choices of the closed category. There is a Brauer group functor from the category of commutative monoids in the closed category to the category of Abelian groups. For a finitely bicomplete closed category V [8, p.

Improving Digital Transformation Outcomes and Pace: The Role of the Board and C‐Suite in Reducing Transformation Friction

Information Systems Journal, EarlyView.
ABSTRACT Most organisations are confronting a dilemma: the need to embark on digital transformation to be competitive and sustainable versus the inherently high costs and extremely high risks involved. Lack of executive support has long been identified as a leading cause of project failure, including digital transformation projects.

Tori and surfaces violating a local-to-global principle for rationality

Comptes Rendus. Mathématique
We show that even within a class of varieties where the Brauer–Manin obstruction is the only obstruction to the local-to-global principle for the existence of rational points (Hasse principle), this obstruction, even in a stronger, base change invariant ...

Conspiracy Mentality, Conspiracy Beliefs, and the Four Socio‐Psychological Levels of Analysis: A Latent Profile Moderation Analysis

Journal of Applied Social Psychology, EarlyView.
ABSTRACT The relationship between conspiracy mentality (CM) and belief in specific conspiracy theories (CBs) has been described as bidirectional, but it remains unclear under which socio‐psychological conditions each direction of the relationship is reinforced.

Révision de l’espèce Homo erectus (Dubois, 1893)

Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2000
The hypodigm for Homo erectus is a problem which remains unresolved. Most disagreements are based on chronological rather than morphological data. A methodology based neither on simple global similarity nor on chronological position is required to ...

Conservation genomics of Pecos pupfish (Cyprinodon pecosensis)

Journal of Fish Biology, EarlyView.
Abstract The Pecos pupfish, Cyprinodon pecosensis, is an imperilled freshwater fish found in arid regions of Texas and New Mexico (USA). The species faces multiple challenges to persistence including reductions in suitable habitat, water shortages, as well as hybridization and competition with an introduced congener (sheepshead minnow, C.

Dissecting the genetic basis of climatic adaptation in wild relatives (Malus baccata) for climate‐resilient apple breeding

Journal of Integrative Plant Biology, EarlyView.
This comprehensive map of genetic variation in wild apple (Malus baccata) and set of key genes associated with adaptation to temperature, precipitation, and soil properties establishes a foundation for breeding climate‐resilient apple cultivars and conserving the genetic resources of wild crop relatives.
