The fundamental plane of elliptical galaxies with modified Newtonian dynamics [PDF]

, 1999
The modified Newtonian dynamics (MOND), suggested by Milgrom as an alternative to dark matter, implies that isothermal spheres with a fixed anisotropy parameter should exhibit a near perfect relation between the mass and the fourth power of the velocity ...

Equilibrium Propagation for Dissipative Dynamics

Advanced Intelligent Systems, EarlyView.
This work develops local learning rules for damped linear dynamical systems, including mechanical structures and resistor‐inductor‐capacitor (RLC) circuits, by leveraging an effective action formulation. It demonstrates how physical systems can autonomously compute gradients and learn temporal patterns, enabling applications such as sound ...

Phase mixing in MOND [PDF]

, 2007
Dissipationless collapses in Modified Newtonian Dynamics (MOND) have been studied by using our MOND particle-mesh N-body code, finding that the projected density profiles of the final virialized systems are well described by Sersic profiles with index ...

Robotic Arm‐Assisted Conformal 3D Printing of Displays for Structural Electronics

Advanced Intelligent Systems, EarlyView.
This study presents a robotics‐enabled platform combining 3D scanning and a 6‐DOF robotic arm for conformal printing on complex non‐planar structures. By maintaining nozzle perpendicularity, the system enables high‐fidelity direct ink writing on steep sidewalls, spherical surfaces, successfully demonstrating a fully printed 7‐segment dynamic display ...

Lung maneuvers of large amplitudes for probing physiological alterations in mouse models of asthma

Animal Models and Experimental Medicine, EarlyView.
Lung maneuvers of small amplitudes, such as the ones performed in oscillometry, are the current gold standard to probe lung mechanics in animals, but they are insensitive to detect baseline physiological alterations in mouse models of asthma. Herein, lung maneuvers of different amplitudes were compared in two mouse models of asthma.

Dark matter and Modified Newtonian Dynamics in a sample of high-redshift galaxy clusters observed with Chandra

, 2009
We compare the measurement of the gravitational mass of 38 high-redshift galaxy clusters observed by Chandra using Modified Newtonian Dynamics (MOND) and standard Newtonian gravity.

Modified Newtonian dynamics and the Coma cluster

The Astronomical Journal, 1988
The consistency of Milgrom's theory of modified Newtonian dynamics is checked against optical and X-ray data for the Coma cluster of galaxies. It is found that viable models for the cluster containing no dark matter can be constructed. They require an extensive gaseous atmosphere through which galaxies move on near-radial orbits. The gas temperature is

Impact of Pumpkin and Carrot Flours on the Oxidative and Rheological Properties: Properties of Low‐Fat Cold‐Pressed Oil Mayonnaise

Journal of the American Oil Chemists' Society, EarlyView.
Partial substitution of sunflower oil with cold‐pressed oils (0‐20%) improves the bioactive composition, oxidative stability, and overall quality of mayonnaise while preserving emulsion stability. ABSTRACT This study investigates the effects of xanthan gum, carrot flour, and pumpkin flour on the physicochemical, rheological, and bioactive properties of

Comparison of HMG and Flat Rotation Velocities Inferred from Galaxy–Galaxy Weak Lensing

The Astrophysical Journal
Despite the success of dark matter models, unresolved issues require exploring alternatives such as modified gravity theories. In this context, we examine the compatibility of the hyperconical modified gravity (HMG) with galaxy rotation curves inferred ...

Galaxy groups and the modified dynamics

, 1998
I estimate Modified-Dynamics (MOND), median M/L values for recently published catalogues of galaxy groups. While the median, Newtonian M/L values quoted for these catalogues are 110-200 solar units, the corresponding values for MOND are less than 10 ...
