ABSTRACT OAO 1657?415 is an atypical supergiant X-ray binary among wind- and disc-fed systems, showing alternate spin-up/spin-down intervals lasting of the order tens days. We study different torque states based on spin history monitored by Fermi/Gamma-Ray Burst Monitor, together with fluxes from Swift/Burst Alert Telescope (BAT) Monitor All-sky Image/Gas Slit Camera. Its frequency derivatives ...

El objetivo de este trabajo es proponer una interpretación del símil Eneida 8.407-415 desde el enfoque los estudios acerca la identidad romana en Eneida. La caracterización femina que lo protagoniza participa, a nuestro entender, configuración “lo romano” presentada poema. En sentido, consideramos posible formular lectura alternativa irónica o cómica tradicionalmente se ha realizado.

Titanium metal–organic frameworks (Ti-MOFs), as an appealing type of artificial photocatalyst, have shown great potential in the field solar energy conversion due to their well-studied photoredox activity (similar TiO2) and good optical responsiveness linkers, which serve antenna absorb visible-light. Although much effort has been dedicated developing Ti-MOFs with high photocatalytic activity, ...

Abstract Let $p_{\{3, 3\}}(n)$ denote the number of $3$ -regular partitions in three colours. Da Silva and Sellers [‘Arithmetic properties 3-regular colours’, Bull. Aust. Math. Soc. 104 (3) (2021), 415–423] conjectured four Ramanujan-like congruences modulo $5$ satisfied by . We confirm these conjectural using theory modular forms.
