Photon rings as tests for alternative spherically symmetric geometries with thin accretion disks

open access: yes, 2023
The imaging by the Event Horizon Telescope (EHT) of the supermassive central objects at the heart of the M87 and Milky Way (Sgr A⋆) galaxies, has marked the first step into peering at the photon rings and central brightness depression that characterize ...

Tripping the light fantastic: exploring the imaginative geographies of Lord of the Rings ‘film tourism’ in New Zealand [PDF]

open access: yes, 2009
From screen image to imagined spaces, the Lord of the Rings film-tourism experience – that is, tourism to New Zealand apparently motivated by the popular film trilogy which was filmed there – has received much anecdotal attention, yet little scholarly ...

SMARANDACHE LOOPS [PDF]

open access: yes, 2002
The theory of loops (groups without associativity), though researched by several mathematicians has not found a sound expression, for books, be it research level or otherwise, solely dealing with the properties of loops are absent.

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.

Hereditary Radicals in Associative and Alternative Rings

open access: yes, 1965
In the first part of this paper we shall consider associative rings, pointing out where associativity is required. In the second part we shall consider not necessarily associative rings and in particular alternative rings.A property S of rings is said to

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
