A team of researchers from Indiana University, along with international collaborators, is actively engaged in unraveling fundamental mysteries surrounding the fundamental laws of physics that......

It's never easy to move such massive logs—but some ancient people used their heads. Deposit PhotosPlus other fun facts from The Weirdest Thing I Learned This Week. The post This ancient civilization literally used their heads to move massive logs for miles appeared first on Popular Science....

A combined machine learning-Physics-based approach for the thermodynamic design of complex systems is introduced and applied....

Neutrinos are bizarre and ubiquitous and may just break the rules of physics...

Modeling gas flow through fractures of subsurface rock is a particularly challenging problem because of the heterogeneous nature of the material. High-fidelity simulations using discrete fracture network (DFN) models are one methodology for predicting gas particle breakthrough times at the surface, but are computationally demanding. We propose a Bayesian machine...

The theory of temperature jets gets extended to account for the influence of the beta effect on their dynamics. Including this effect noticeably changes symmetry properties and laws of conservation inherent to models without the beta effect. Especially nontrivial, the dynamics of jets become near the equator, where the model...

Understanding the receptivity of hypersonic flows to free-stream disturbances is crucial for predicting laminar to turbulent boundary layer transition. Input-output analysis as a receptivity tool considers which free-stream disturbances lead to the largest response from the boundary layer using the global linear dynamics. Two technical challenges are addressed. First, we...

Dielectric elastomers are widely studied for their use in robotic and medical devices due to their shape changing properties. Recently, they have also been incorporated into acoustic devices, motivating the development of an electroacoustic model for dielectric elastomers. This paper provides a lumped element model based on a prestretched membrane...

Many types of detectors, such as cathode strip chambers and some MPGDs, allow us to reconstruct track positions by induced strip charges. There are two main types of algebraic methods for this reconstruction: center of gravity methods and little-known differential methods. General formulas for differential methods are derived. Their performance...

The binding-energy differences for $^{163}mathrm{Ho}^{q+}$ and $^{163}mathrm{Dy}^{q+}$ ions with ionization degrees $q = 38$, $39$, and $40$ are calculated. The calculations are performed using the large-scale relativistic configuration-interaction and relativistic coupled-clusters methods. The contributions from quantum-electrodynamics, nuclear-recoil, and frequency-dependent Breit-interaction effects are taken into account. The final uncertainty does not...

Many microorganisms propel through complex media by deformations of their flagella. The beat is thought to emerge from interactions between forces of the surrounding fluid, passive elastic response from deformations of the flagellum, and active forces from internal molecular motors. The beat varies in response to changes in the fluid...

We propose a dynamical systems approach to show how multizone models in buildings can be simplified upon recognising the existence of fast and slow modes of response. The study is motivated by extensive observations from an instrumented classroom equipped with 70 computers used heterogeneously in time and space, a living...
