Certain Fourier Operators and their Associated Poisson Summation Formulae on $\mathrm{GL}_1$ [PDF]

open access: yesPacific J. Math. 326 (2023) 301-372, 2021
In this paper, we explore a possibility to utilize harmonic analysis on $\GL_1$ to understand Langlands automorphic $L$-functions in general, as a vast generalization of the pioneering work of J. Tate. For a split reductive group $G$ over a number field $k$, let $G^\vee(\BC)$ be its complex dual group and $\rho$ be an $n$-dimensional complex ...

Smooth Infinitesimals in the Metaphysical Foundation of Spacetime Theories [PDF]

open access: yesJournal of Philosophical Logic volume 51, pages 857-877 (2022), 2023
I propose a theory of space with infinitesimal regions called \textit{smooth infinitesimal geometry} (SIG) based on certain algebraic objects (i.e., rings), which regiments a mode of reasoning heuristically used by geometricists and physicists (e.g., circle is composed of infinitely many straight lines). I argue that SIG has the following utilities. (1)

Multi‐omics analyses reveal the interaction between colonic microbiota and host in Min and Yorkshire pigs

open access: yesAnimal Research and One Health, EarlyView., 2023
In the present study, we created the weight gain models with Min and Yorkshire pigs and conducted the metagenomics and metabolomics of colon contents and transcriptomics of colon tissue. Further, we revealed the characteristics and functions of the colonic microbiota in Min and Yorkshire pigs and analyzed their interactions with the host. Overall, this

Herramientas SIG 3D

open access: yesVirtual Archaeology Review, 2010
<p>Applications of Geographical Information Systems on several Archeology fields have been increasing during the last years. Recent avances in these technologies make possible to work with more realistic 3D models. In this paper we introduce a new paradigm for this system, the GIS Thetrahedron, in which we define the fundamental elements of GIS ...

A publishing modality to advance social justice: an African experience

open access: yes027.7
There are many Africans who hold the view that the philanthropic underpinnings of the openness movement have been hijacked by commercial publishers, violating the altruistic principles of open access to advance a business model that guarantees exorbitant
