arXiv:2606.04533v1 Announce Type: cross Abstract: A vibrational paradigm of atomic dynamic in dense fluids is known to provide useful insight on the transport and thermodynamic properties of fluids in three dimensions. In this paper, a vibrational model is generalized to describe the excess entropy of two-dimensional (2D) fluids. A simple practical implementation of this model is demonstrated to deliver accurate results for various systems, such as one-component plasmas with Coulomb and...

arXiv:2606.04533v1 Announce Type: cross Abstract: A vibrational paradigm of atomic dynamic in dense fluids is known to provide useful insight on the transport and thermodynamic properties of fluids in three dimensions. In this paper, a vibrational model is generalized to describe the excess entropy of two-dimensional (2D) fluids. A simple practical implementation of this model is demonstrated to deliver accurate results for various systems, such as one-component plasmas with Coulomb and logarithmic interactions, a 2D fluid of dipole particles, and a 2D Yukawa fluid. The applicability limits, relevance to three-dimensional fluids, relations to other 2D phenomena, and potential practical applications are briefly discussed.

After NSIL’s PPP bid, IN-SPACe opens LVM-3 to private sector with ToT push

In a renewed push to hand over Isro’s LVM-3 launch vehicle to private industry, space regulator-cum-promoter Indian National Space Promotion and Authorisation Centre (IN-SPACe) has invited expressions of interest (EoI) for the transfer of technology (ToT) of the country’s heaviest operational rocket. The move comes more than two years after Space PSU NewSpace India Limited (NSIL) had sought private partners to scale up production of the launch vehicle through a public-private partnership...

NASA chief defends all-male Artemis 3 astronaut crew amid backlash: 'I don't think anyone should be reading into this' "Our last astronaut candidate class was greater than 50% female. We'll assemble the best astronauts to undertake and complete the objectives." The four astronauts comprising the Artemis 3 crew announced this week are all male, but NASA officials emphasized they were selected based on qualifications and not to exclude any genders.
