Competing Mechanisms at Vibrated Interfaces of Density-Stratified Fluids
Fluid--fluid interfacial instability and subsequent fluid mixing are ubiquitous in nature and engineering. Two hydrodynamic instabilities have long been thought to govern the interface behavior: the pressure gradient-driven long-wavelength Rayleigh--Taylor (RT) instability and resonance-induced short-wavelength Faraday instability. However, neither instability alone can explain the dynamics when both mechanisms act concurrently. Instead, we identify a previously unseen multi-modal instability e…

Es hat ein bisschen gebraucht, bis ich mich durch Track Changes: A Literary History of Word Processing durchgekämpft hatte. Natürlich hat die Erwähnung alter Bekannter eine kleine Retro-Reise zu alten Schreibprogrammen ausgelöst, die noch nicht zu Ende ist. Ein paar Gedanken dazu für Interessierte hier:

A Smart-Contract to Resolve Multiple Equilibrium in Intermediated Trade
We present a model of a market that is intermediated by broker-dealers where there is multiple equilibrium. We then design a smart-contract that receives messages and algorithmically sends trading instructions. The smart-contract resolves the multiple equilibrium by implementing broker-dealer joint profit maximization as a Nash equilibrium. This outcome relies upon several factors: Agent commitments to follow the smart contract protocol; selective privacy of information; a structured timing of …

BrainMRDiff: A Diffusion Model for Anatomically Consistent Brain MRI Synthesis
Accurate brain tumor diagnosis relies on the assessment of multiple Magnetic Resonance Imaging (MRI) sequences. However, in clinical practice, the acquisition of certain sequences may be affected by factors like motion artifacts or contrast agent contraindications, leading to suboptimal outcome, such as poor image quality. This can then affect image interpretation by radiologists. Synthesizing high quality MRI sequences has thus become a critical research focus. Though recent advancements in co…

Adhesion differentials control the rheology of biomimetic emulsions
Animal morphogenesis involves complex tissue deformation processes, which require tight control over tissue rheology. Yet, it remains insufficiently understood how tissue rheology results from the interplay between cellular packing and cellular forces, such as cortical tension, cell pressure, and cell-cell adhesion. Here, we follow a biomimetic approach to study this interplay, focusing on the cellular adhesion hierarchy. We mimic adhesive cells with oil droplets whose adhesion strength and spe…

Low scale leptogenesis and $TM_1$ mixing in neutrinophillic two Higgs doublet model($ν$2HDM) with S4 flavor symmetry
We study a modified version of the Standard Model that includes a scalar doublet and two right-handed neutrinos, forming the neutrinophillic two higgs doublet ($ν\text{2HDM}$) framework. For $v_2 << v_1$, this model operates at a TeV scale, bringing the RHNs within experimental reach. To further enhance its predictive power, we introduce an $S_4 \times Z_4$ flavor symmetry with five flavons, resulting in mass matrices that realize $\text{TM}_1$ mixing. The model effectively explains lepton mas…

How probable is the Lyman-$α$ damping wing in the spectrum of the redshift z = 5.9896 quasar ULAS J0148+0600?
The shape of the Ly-$α$ transmission in the near zone of the redshift $z=5.9896$ quasar ULAS J0148$+$0600 (hereafter J0148) is consistent with a damping wing arising from an extended neutral hydrogen island in the diffuse intergalactic medium (IGM). Here we use simulations of late-ending reionisation from Sherwood-Relics to assess the expected incidence of quasars with Ly-$α$ and Ly-$β$ absorption similar to the observed J0148 spectrum. We find a late end to reionisation at $z=5.3$ is a nece…

Softness and Hydrodynamic Interactions Regulate Lipoprotein Transport in Crowded Yolk Environments
Low-density lipoproteins (LDLs) serve as nutrient reservoirs in egg yolk for embryonic development and as promising drug carriers. Both roles critically depend on their mobility in densely crowded biological environments. Under these crowded conditions, diffusion is hindered by transient confinement within dynamic cages formed by neighboring particles, driven by solvent-mediated hydrodynamic interactions and memory effects -- phenomena that have remained challenging to characterize computationa…
