Modified Newtonian Dynamics Close to Home [PDF]
In his Perspective “Seeing through Dark Matter” (3 August, p. 607), Stacy McGaugh describes the success of a modified Newtonian dynamics (MOND) in explaining the flat rotation curves of galaxies without invoking dark matter.

MOND: uma alternativa à mecânica newtoniana [PDF]
O objetivo do presente trabalho é expor os principais aspectos e resultados de uma das mais populares alternativas à teoria newtoniana para o movimento dos corpos conhecida por Modified Newtonian Dynamics (MOND, na sigla em inglês).

A cusp-core-like challenge for modified Newtonian dynamics [PDF]
We show that modified Newtonian dynamics (MOND) predicts distinct galactic acceleration curve geometries – in the space of total observed centripetal accelerations, gtot, versus the inferred Newtonian acceleration from baryonic matter, gN, which we refer

Using pixel‐aware digital light processing, the authors created high‐resolution, dissolvable microneedles from a PEGDA/VP matrix. These microneedles encapsulate curcumin and 5‐fluorouracil and dissolve in the skin, co‐delivering drugs directly to tumours.

The Acceleration Scale, Modified Newtonian Dynamics and Sterile Neutrinos [PDF]
General Relativity is able to describe the dynamics of galaxies and larger cosmic structures only if most of the matter in the Universe is dark, namely it does not emit any electromagnetic radiation. Intriguingly, on the scale of galaxies, there is strong observational evidence that the presence of dark matter appears to be necessary only when the ...

Cosmological extrapolation of modified Newtonian dynamics [PDF]
The regime of modified Newtonian dynamics (MOND), which is used in astronomy to describe gravitating systems of the island type without the need to postulate the existence of a hypothetical dark matter, is generalized to the case of homogeneous distribution of usual matter by introducing a linear dependence of the critical acceleration on the size of ...

Modified Newtonian dynamics (MOND) was originally proposed to model galaxy rotation curves without dark matter. However, MOND presents difficulties in explaining the radial acceleration relation observed in galaxy clusters, and moreover, it does not ...

A quantum state for the late Universe
We consider the quantum description of a toy model universe in which the Schwarzschild-de Sitter geometry emerges from the coherent state of a massless scalar field.

Hydrogel‐Based Airway‐on‐Tube With Perfusable Endothelial Lumen and Outward Epithelialization
A hydrogel‐based airway‐on‐tube platform featuring a perfusable endothelial lumen and outward epithelialization is presented. The system supports primary human bronchial epithelial and lung microvascular endothelial coculture under air‐liquid interface conditions.

On the origin of the inertia: The modified Newtonian dynamics theory [PDF]
The sameness between the inertial mass and the gravitational mass is an assumption and not a consequence of the equivalent principle is shown. In the context of the Sciama’s inertia theory, the sameness between the inertial mass and the gravitational mass is discussed and a certain condition which must be experimentally satisfied is given. The inertial
