Background a 36-year-old woman, with a history of childhood asthma allergic to house dust mites, noticed one year prior to her arrival at our unit an episode of generalized itching, dyspnea, severe rhinoconjunctivitis and abdominal pain after eating rice with razor shell. After that, she had tolerated rice alone. Razor shell (Ensis ensis) is a common mollusc, which has an elongated fragile and ...

Metal-semiconductor Janus-like nanoparticles with the composition tantalum silicide-silicon (TaSi₂/Si) were synthesized for the first time by means of an evaporation method utilizing a high-power electron beam. The composition of the synthesized particles were characterized using high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), selective area electron diffracti...

Poly(amino acid)-coated gold nanoparticles hold promise in biomedical applications, particularly because they combine the unique physicochemical properties of the gold core, excellent biocompatibility, and easy functionalization of the poly(amino acid)-capping shell. Here we report a novel method for the preparation of robust hybrid core-shell nanosystems consisting of a Au144 cluster and a den...

We present general analytic expressions for GRB afterglow light curves arising from a variable external density profile and/or a variable energy in the blast wave. The former could arise from a clumpy ISM or a variable stellar wind; The latter could arise from refreshed shocks or from an angular dependent jet structure (patchy shell). Both scenarios would lead to a variable light curve. Our for...

Generalized Bernstein-like functions (gB-like functions) with different shape parameters are used in this work. Parametric and geometric conditions generalized form developed. Some numerical examples of the parametric continuity (PC) (GC) constraints Bézier-like curves curves) analyzed graphical representation. symmetric rotation surfaces constructed by gB-like curves. Vase Capsule Taurus model...

It is well known that gold cluster can have planar or hollow cagelike structure due to the relativistic effect. In this study, by first principles calculation on the Au(58) cluster, we propose that gold cluster of medium size can form a shell-like structure, which is demonstrated by the remarkable robustness of a double shell structure with a hollow inner shell of ten atoms.

We consider a shell-like three-dimensional nonlinearly hyperelastic body and we let its thickness go to zero. We show, under appropriate hypotheses on the applied loads, that the deformations that minimize the total energy weakly converge in a Sobolev space toward deformations that minimize a nonlinear shell membrane energy. The nonlinear shell membrane energy is obtained by computing the Γ-lim...
