A genealogy of fish women and other imagined identities: “The mechanics of fluids” in Larissa Lai's Salt Fish Girl

Orbis Litterarum, Volume 80, Issue 6, Page 602-618, December 2025.
Abstract Fluidity invigorates a utopian home in Chinese Canadian author Larissa Lai's Salt Fish Girl (2002). In the novel, the fishlike lesbian couple cyclically returns to their aquatic habitat between mortal reincarnations: from last‐century colonial South China to near‐future bio‐capitalistic Canada, where they recurrently experience displacement ...

Primordial black holes as supermassive black hole seeds

Journal of Cosmology and Astroparticle Physics
Abstract The presence of supermassive black holes (SMBHs, M • ∼ 106-10 M ⊙) in the first cosmic Gyr (z ≳ 6) challenges current models of BH formation and evolution. We propose a novel mechanism for the formation of early SMBH seeds based on primordial black holes (PBHs).

Structure of the Baryon Halo Around a Supermassive Primordial Black Hole

Particles
According to some theoretical models, primordial black holes with masses of more than 108 solar masses could be born in the early universe, and their possible observational manifestations have been investigated in a number of works. Dense dark matter and

Enhanced detectability of spinning primordial black holes

European Physical Journal C: Particles and Fields, 2020
Primordial black holes which are produced during an epoch of matter domination are expected to spin rapidly. It is shown that this leads to an enhancement of the detectability of the stochastic gravitational-wave background from their mergers.

Astrophysical constraints on primordial black holes in Brans-Dicke theory

, 2010
We consider cosmological evolution in Brans-Dicke theory with a population of primordial black holes. Hawking radiation from the primordial black holes impacts various astrophysical processes during the evolution of the Universe.

Advances in Topological Thermoelectrics: Harnessing Quantum Materials for Energy Applications

Advanced Materials, Volume 37, Issue 39, October 2, 2025.
Topological materials offer a novel platform for thermoelectric energy conversion through unique band features, including band inversion, linear Dirac bands, surface states, and Berry curvature. These quantum characteristics enable enhanced longitudinal and transverse thermoelectric effects, establishing topological thermoelectrics as a promising ...

Gravitational waves from primordial black holes and new weak scale phenomena

Physics Letters B, 2017
We entertain the possibility that primordial black holes of mass ∼(1026–1029) g, with Schwarzschild radii of O(cm), constitute ∼10% or more of cosmic dark matter, as allowed by various constraints.

A Note on Gravitational Memory in F(R)-theories and their Equivalent Scalar-Tensor Theories [PDF]

, 2014
In this paper we consider the implications that the effect gravitational memory would have on primordial black holes, within the theoretical context of $F(R)$ related scalar-tensor theories.

Robust and Efficient FFT‐Based Solvers for Unit‐Cell Problems With Voids and Pores Under Displacement Boundary Conditions

International Journal for Numerical Methods in Engineering, Volume 126, Issue 18, 30 September 2025.
ABSTRACT There is a variety of microstructured materials that involve voids and pores, for example, high‐porosity foams, mechanical metamaterials, or composites involving defects due to damage and cracking, respectively. Computational methods based on the fast Fourier transform (FFT) typically face convergence problems for such microstructures unless ...

Antinuclei from primordial black holes

Physical Review D
Light primordial black holes (PBHs) may have originated in the early Universe, and could contribute to the dark matter in the Universe. Their Hawking evaporation into particles could eventually lead to the production of antinuclei, which propagate and arrive at Earth as cosmic rays with a flux peaked at GeV energies.
