Well posedness and comparison principle for option pricing with switching liquidity [PDF]
Nonlinear Analysis: Real World Applications, 2015 We consider an integro-differential equation derived from a system of coupled parabolic PDE and an ODE which describes an European option pricing with liquidity shocks.

Advances in Nonlinear Analysis, 2014 We obtain a new Liouville comparison principle for weak solutions (u,v) of semilinear parabolic second-order partial differential inequalities of the form ut-ℒu-|u|q-1u≥vt-ℒv-|v|q-1v(*)$u_t -{\mathcal {L}}u- |u|^{q-1}u\ge v_t -{\mathcal {L}}v- |v|^{q-1}v\

A comparison principle for the porous medium equation and its consequences [PDF]
, 2015 We prove a comparison principle for the porous medium equation in more general open sets in $\mathbb{R}^{n+1}$ than space-time cylinders. We apply this result in two related contexts: we establish a connection between a potential theoretic notion of the ...

Principles of Germplasm Comparisons
Journal of Dairy Science, 1987 Abstract Design of germplasm comparisons depends on the hypothesis to be tested. Most important hypotheses concern the future environment for production and marketing. 1) Will the best bulls in an exotic breed improve a local breed?; 2) Is it efficient to upgrade a local breed with bulls from a related exotic breed that has a large, effective program ...

Comparison principles for self-similar potential flow [PDF]
Proceedings of the American Mathematical Society, 2011 We establish a strong comparison principle, as well as a weak comparison principle and a Hopf-type lemma, for elliptic solutions of the self-similar potential flow equation. A major difference from the steady case is that the coefficients of the equation depend on the potential function itself, as well as its gradient.

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.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

A strong comparison principle for the $p$-Laplacian [PDF]
Proceedings of the American Mathematical Society, 2007 Summary: We consider weak solutions of the differential inequality of \(p\)-Laplacian type \[ -\Delta_p u - f(u) \leq - \Delta_p v - f(v) \] such that \(u\leq v\) on a smooth bounded domain in \(\mathbb R^N\) and either \(u\) or \(v\) is a weak solution of the corresponding Dirichlet problem with zero boundary condition.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only
