There really ought to be an academy award for “most entertaining film” because that’s really all I care about and “best picture” has always been, well, self-aggrandizing nonsense

Abstract: Magnetotactic bacteria (MTB) are of significant fundamental and practical interest, especially for applications such as drug delivery and general-purpose object manipulators and payload carriers. While magnetic and other modes of control for individual MTB have been demonstrated, formation, motion and control of MTB swarms are much less studied and understood. Here, we present a torque dipole-based theoretical model for magnetic control of MTB swarms and two methods for swarm formation, and provide experimental validation of the proposed motion model. Model predictions are in good qualitative and quantitative agreement with experiments and literature. Additionally, we were able to determine the torque generated by Magnetospirillium gryphiswaldense (MSR-1) MTB, and the value corresponds to the reported estimates reasonably well.

Dallas Cowboys Could Emerge As Ryan Tannehill Suitor
Amidst uncertainty surrounding Dak Prescott‘s future with the Dallas Cowboys, the prospect of acquiring a seasoned quarterback gains considerable appeal for the team’s front office. Patrik Walker of DallasCowboys.com recently proposed the idea of former Tennessee Titans quarterback Ryan Tannehill as a viable option in free agency. “A look at Tannehill might be worth it in the realm of possibly being a potential upgrade to Rush, while also providing insurance in the event Lance doesn’t p…

Abstract: We study the propagation of both low- and high-amplitude ring-shaped sound waves in a 2D square lattice of acoustic waveguides with Helmholtz resonators. We show that the inclusion of the Helmholtz resonators suppresses the inherent anisotropy of the system in the low frequency regime allowing for radially symmetric solutions. By employing the electroacoustic analogue approach and asymptotic methods we derive an effective cylindrical Korteweg de Vries (cKdV) equation. Low-amplitude waveforms are self-similar structures of the Airy function profile, while high-amplitude ones are of the form of cylindrical solitons. Our analytical predictions are corroborated by results of direct numerical simulations, with a very good agreement between the two.

Interplay between Vector-like Lepton and Seesaw Mechanism:Oblique Corrections

Abstract: The non-vanishing neutrino mass strongly hints the existence of right-handed neutrinos (RHNs), singlets of the standard model (SM). However, they are highly decoupled from the SM and difficult to probe. In this work, we consider the Majorana RHNs from the type-I seesaw mechanism may well mix with the heavy neutral lepton dwelling in certain vector-like lepton (VLL), thus acquiring a sizable electroweak charge. Such a simple scenario yields many interesting consequences, and the imprint on oblique corrections, well expected from the mass splitting between components of VLL by virtue of VLL-RHN mixing, is our focus here. We analytically calculate the Peskin-Takeuchi parameters S, T and U with full details, carefully treating the Majorana loop to obtain the self consistent expressions free of divergence. Then, we constrain on the VLL-RHN system which only gives a sizable $T$ parameter using the PDG-2021 data and CDF-II data, separately, by imposing $T\lesssim{\cal O}(0.1)$. It is found that for the RHN and VLL below the TeV scale, with a properly large mixing, stands in the frontier of the electroweak precision test such as W-boson mass.

I have given evidence to Oireachtas Committees quite a few times over the years. They have run the gamut from professional, inquiring and constructive to, um, not that.
The format relies entirely on the legislators attending wanting to make it work and respecting their witnesses (even if not agreeing with them).
Having voluntary witnesses refuse to attend for fear of being mistreated undermines the opportunities for those constructive inquiries.
