Screw‐Based Pill for Intelligent Robotic Extraction of Viscous Fluids in Medical Applications

Advanced Intelligent Systems, EarlyView.
Screw‐based pill for intelligent robotic extraction (S‐PIRE) is a magnetically actuated smart capsule with a motorized screw, 3‐axis sensor, and Bluetooth control for site‐specific and minimally invasive remote sampling of viscous fluids, overcoming passive diffusion limitations.

A Novel Test for MOND: Gravitational Lensing by Disk Galaxies

The Astrophysical Journal
Disk galaxies represent a promising laboratory for the study of gravitational physics, including alternatives to dark matter (DM), owing to the possibility of coupling rotation curves’ dynamical data with strong gravitational lensing (SGL) observations ...

Radial-orbit instability in modified Newtonian dynamics

, 2011
The stability of radially anisotropic spherical stellar systems in modified Newtonian dynamics (MOND) is explored by means of numerical simulations performed with the N-body code N-MODY.

A Miniature Rotary Electrostatic Clutch for Assigning Multi‐Degrees of Freedom to Insect‐Scale Robots

Advanced Intelligent Systems, EarlyView.
Insect‐scale crawling robots can traverse confined environments; nevertheless, their functionalities are predominantly restricted to sensing because of challenges in integrating actuated degrees of freedom. Herein, a miniature rotary electrostatic clutch is presented by incorporating cutting patterns in the clutch layer.

Quantum GraviElectro Dynamics

Annalen der Physik, EarlyView.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Jeans analysis in fractional gravity

European Physical Journal C: Particles and Fields
It has recently been demonstrated (Giusti in Phys Rev D 101:124029, 2020, https://doi.org/10.1103/PhysRevD.101.124029 ) that characteristic traits of Milgrom’s modified Newtonian dynamics (MOND) can be replicated from an entirely distinct framework: a ...

Buoyancy‐Driven Micropolar Fluid Flow Transport in Porous Media With Variable Heat Source and Convective Heating

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The objective of the current research is to characterize the thermal performance in micropolar fluid flows on a vertically elongated porous sheet in the presence of buoyancy forces. Thus, the motivation of this study is to improve the understanding of buoyancy‐driven micropolar fluid flows through porous media, which are relevant to advanced ...

Rotation Curve with MOND and Dark Matter Halo profile for ESO138-G014 [PDF]

, 2014
This paper is devoted to solve the galactic rotation problem for ESO138-G014 galaxy based on two theories: dark matter and Modified Newtonian Dynamics. Here we did the rotation curve analysis with two possible choices for the dark matter density profile,
