Benefits from Variational Regularization in Language Models

open access: yesMachine Learning and Knowledge Extraction, 2022
Representations from common pre-trained language models have been shown to suffer from the degeneration problem, i.e., they occupy a narrow cone in latent space. This problem can be addressed by enforcing isotropy in latent space.

The Isotropy of Compact Universes [PDF]

open access: yes, 2001
We discuss the problem of the stability of the isotropy of the universe in the space of ever-expanding spatially homogeneous universes with a compact spatial topology.

A Lagrangian model for atmospheric pollutant diffusion

open access: yesMeteorologische Zeitschrift, 1994
Equations for particle motion, particle potential temperature and mass fractions of chemical components are determined completely consistent with the budget equations for the means and variances assuming locally isotropic dissipation and a return-to ...

Anisotropic alumina ceramics with isotropic optical properties

open access: yesJournal of Advanced Ceramics, 2023
Excellent mechanical and isotropic optical properties are achieved simultaneously from fully dense polycrystalline advanced alumina ceramics with a hexagonal crystal structure, which are optically anisotropic. A small amount (240 ppm) of ZrO2 additive is

Study of isotropy of mechanical properties of the TPMS-based cellular structures [PDF]

open access: yesE3S Web of Conferences, 2022
The study of isotropy of mechanical properties of cellular structures was carried out. The studied objects are based on triply periodic minimal surfaces (“Schwarz primitive”) with various cell size parameter t.

Appearance of Supersonic Stoneley Waves in Auxetics

open access: yesCrystals, 2022
It is shown that in auxetic materials (materials with negative Poisson’s ratio), supersonic Stoneley waves travelling without attenuation with a velocity equal to or exceeding maximum bulk wave velocity, may exist. Analytical expressions for the relation

Bianchi I Model: An Alternative Way To Model The Presentday Universe [PDF]

open access: yes, 2014
Although the new era of high precision cosmology of the cosmic microwave background (CMB) radiation improves our knowledge to understand the infant as well as the presentday Universe, it also leads us to question the main assumption of the exact isotropy
