Efficient generation of divergent and collimated hot electrons via a novel multi-beam two-plasmon decay and stimulated Raman scattering mechanism [PDF]

Matter and Radiation at Extremes
In inertial confinement fusion (ICF) implosions, the preheating risks associated with hot electrons generated by laser–plasma instabilities are contingent upon the angular characteristics of these hot electrons for a given total energy. Using particle-in-

Green bundles, Lyapunov exponents and regularity along the supports of the minimizing measures

, 2012
In this article, we study the minimizing measures of the Tonelli Hamiltonians. More precisely, we study the relationships between the so-called Green bundles and various notions as: - the Lyapunov exponents of minimizing measures; -the weak KAM solutions.

Dispensing Volumetric Additive Manufacturing

Advanced Functional Materials, EarlyView.
Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...

Contingent and Intermediate Tangent Cones in Hyperbolic Differential Inclusions and Necessary Optimality Conditions

Journal of Mathematical Analysis and Applications, 1994
The author studies some properties of the contingent and intermediate cones to the reachable set of the differential inclusion \(u_{xy} \in F(x,y,u,u_ x,u_ y)\), with boundary conditions of the form \[ u(0,0) \in F_ 0, \;u_ x (x,0) \in F_ 1 \bigl( x,u(x,0) \bigr),\;u_ y(0,y) \in F_ 2 \bigl( y,u (0,y) \bigr).

Adsorption Characteristics and Mechanisms of Dibutyl Phthalate on Nanomaterials

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Dibutyl phthalate (DBP) is a widely used plasticizer whose environmental release poses significant risks to ecosystems and human health. This study systematically investigated DBP adsorption on three common nanomaterials—titanium dioxide nanoparticles (n‐TiO2), multiwalled carbon nanotubes (MWCNTs), and carboxylated MWCNTs (MWCNTs‐COOH)—using ...

An induction theorem and nonlinear regularity models [PDF]

, 2015
A general nonlinear regularity model for a set-valued mapping $F:X\times R_+\rightrightarrows Y$, where $X$ and $Y$ are metric spaces, is considered using special iteration procedures, going back to Banach, Schauder, Lusternik and Graves.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Quantification of rheological parameters in deep‐sea mining plumes

Deep Underground Science and Engineering, EarlyView.
This study explores the variations in rheological properties observed during the propagation of deep‐sea mining plumes, utilizing rheological test data obtained from kaolin clay plumes. Subsequently, taking into account the differences in sediment properties, the effects of clay content and clay mineral composition on the rheological parameters of ...
