Integrable models with unstable particles [PDF]

, 2005
We review some recent results concerning integrable quantum field theories in 1+1 space-time dimensions which contain unstable particles in their spectrum. Recalling first the main features of analytic scattering theories associated to integrable models,

Reactant Jetting in Unstable Detonation [PDF]

, 2009
We note the common existence of a supersonic jet structure locally embedded within a surrounding transonic flow field in the hitherto unrelated phenomena of unstable gaseous detonation and hypervelocity blunt body shock wave interaction. Extending prior

Viscoelastic Pipe Flow is Linearly Unstable. [PDF]

Physical Review Letters, 2017
Newtonian pipe flow is known to be linearly stable at all Reynolds numbers. We report, for the first time, a linear instability of pressure-driven pipe flow of a viscoelastic fluid, obeying the Oldroyd-B constitutive equation commonly used to model ...

New Formulas of Feedback Capacity for AGN Channels with Memory: A Time-Domain Sufficient Statistic Approach

Entropy
Recently, several papers identified technical issues related to equivalent time-domain and frequency-domain “characterization of the n–block or transmission” feedback capacity formula and its asymptotic limit, the feedback capacity, of additive Gaussian ...

Heterogeneous reactions of NO₂ with CaCO₃–(NH₄)₂SO₄ mixtures at different relative humidities [PDF]

Atmospheric Chemistry and Physics, 2016
In this work, the heterogeneous reactions of NO2 with CaCO3–(NH4)2SO4 mixtures with a series of weight percentage (wt %) of (NH4)2SO4 were investigated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) at different relative ...

Unstable fields in Kerr spacetimes [PDF]

, 2012
We show that both the interior region $rM^2$ Kerr naked singularity admit unstable solutions of the Teukolsky equation for any value of the spin weight.

Advances in the Biological Application of Force-Induced Remnant Magnetization Spectroscopy

Molecules, 2022
Biomolecules participate in various physiological and pathological processes through intermolecular interactions generally driven by non-covalent forces. In the present review, the force-induced remnant magnetization spectroscopy (FIRMS) is described and

Structure Functions of Unstable Lithium Isotopes [PDF]

, 2001
We study both the spin-average and spin-dependent structure functions of the lithium isotopes, $^{6-11}$Li, which could be measured at RIKEN and other nuclear facilities in the future.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
