Structural Complexity and Benthic Cover Explain Reef-Scale Variability of Fish Assemblages in Los Roques National Park, Venezuela

open access: yesFrontiers in Marine Science, 2019
Global and local stressors are causing the worldwide loss of coral cover and structural complexity at an unprecedented pace on reefs. In consequence, the habitat of coral reef fish has suffered a profound degradation affecting the abundance, biodiversity

Music and Vague Existence [PDF]

open access: yes, 2017
I explain a tension between musical creationism and the view that there is no vague existence. I then suggest ways to reconcile these views. My central conclusion is that, although some versions of musical creationism imply vague existence, others do not.

Stability results for fractional integral pantograph differential equations involving two Caputo operators

open access: yesAIMS Mathematics, 2023
In this paper, we investigate the existence-uniqueness, and Ulam Hyers stability (UHS) of solutions to a fractional-order pantograph differential equation (FOPDE) with two Caputo operators.

Gunky time and indeterminate existence [PDF]

open access: yes, 2017
The paper criticizes an argument recently presented by Ross Cameron. The argument purports to show that, if time is gunky (that is, if there are no time atoms), and if changes in existence are underwritten by events of coming to be, then there are cases ...

Some results for a variation-inequality problem with fourth order p(x)-Kirchhoff operator arising from options on fresh agricultural products

open access: yesAIMS Mathematics, 2023
In this paper, we study variation-inequality initial-boundary value problems with fouth order p(x)-Kirchhoff operators. First, an operator is constructed based on the Leray Schauder principle, and the existence of solutions is obtained.

Existence of mesons after deconfinement [PDF]

open access: yes, 2007
We investigate the possibility for a quark-antiquark pair to form a bound state at temperatures higher than the critical one ($T>T_c$), thus after deconfinement. Our main goal is to find analytical criteria constraining the existence of such mesons.

IDENTIFICATION OF THE RIGHT HAND SIDE OF A QUASILINEAR PSEUDOPARABOLIC EQUATION WITH MEMORY TERM

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
The study of equations of mathematical physics, including inverse problems, is relevant today. This work is devoted to the fundamental problem of studying the solvability and qualitative properties of the solution of the inverse problem for a ...

Self-realizing a lived existence in service of emancipation: Tsenay Serequeberhan’s activist hermeneutics

open access: yesActa Academica, 2023
Through his own activistic hermeneutics, Sereque­ berhan crafts a philosophy which allows African(a) persons pathways to self­-realization and self­-eman­cipation from Western cultural imperialism.

Einstein solvmanifolds: existence and non-existence questions

open access: yes, 2010
The general aim of this paper is to study which are the solvable Lie groups admitting an Einstein left invariant metric. The space N of all nilpotent Lie brackets on R^n parametrizes a set of (n+1)-dimensional rank-one solvmanifolds, containing the set ...
