“…Again referring to the BHF results [31], we fix this parameter roughly to a 3 = 1000 MeV fm 6 , and this force is termed SL3. For comparison, in the SLL4 ΛN Skyrme force [18], the equivalent optimal parameter is a ΛN 3 ≈ 700 MeV fm 6 , whereas a NN 3 ≈ O(2000 MeV fm 6 ) in typical nucleonic Skyrme forces [29].…”

Motivated by the recently observed hypernucleus (Kiso event) 15 Ξ C ( 14 N+Ξ − ), we identify the state of this system theoretically within the framework of the relativistic-mean-field and Skyrme-Hartree-Fock models. The ΞN interactions are constructed to reproduce the two possibly observed Ξ − removal energies, 4.38 ± 0.25 MeV or 1.11 ± 0.25 MeV. The present result is preferable to be 14 N (g.s.)+Ξ − (1p), corresponding to the latter value.

“…[ 22 ] These biomolecules can engage into specifi c interactions with the NPs, [ 34,47 ] whose surfaces are subsequently modifi ed by their adsorption, which affects colloidal behavior. [56][57][58] Presently, our ability to predict NP behavior in a particular cell medium, with or without different concentrations of serum components, is limited, due to the complex character of the NPs and the media. [ 32,59 ] Likewise, thorough and real-time analytical investigation of the state of dispersion during an experiment is challenging.…”

When nanomaterials meet the biological world, the cellular interaction of nanoparticles is routinely assessed in in vitro systems. Establishing doseresponse relationships requires that the dose of nanoparticles delivered to the cell is accurate and precise. Nanoparticles as such or coated with high molecular-weight compounds are rarely uniform and the infl uence of heterogeneity, including polydispersity both in size and mass density, on the delivered dose is never studied before. Furthermore, a probabilistic term describing particle adherence to cells is introduced and the importance is discussed. By tracing the movement of discrete particles via modeling, it is found that the infl uence of heterogeneity cannot be neglected when the average particle size promotes settling over diffusion. However, the infl uence of polydispersity on the delivered cellular dose is less critical for particulate systems whose mean size promotes diffusion. The infl uence of a non-instantaneous particle association to the cell is negligible for particles whose motion is dominated by settling, but it is relevant for small particles whose motion is governed by diffusion.at least three elementary processes that are relevant for in vitro dose: (i) delivery of NPs to the cell, (ii) adherence to the cell membrane, and (iii) internalization. Any of these processes can be a rate-limiting factor. Awareness concerning the peculiarities of NP transport in fl uids and the relevance to liquid-based in vitro assays is on the rise, as shown by the steadily increasing number of research papers adopting the concept of particokinetics proposed by Teeguarden et al. [ 20,25 ] for interpreting dose-response curves. The concept of particokinetics, describing uniform particles, [ 20,25 ] challenges the still-reigning paradigm that the dose to which adherent cells are exposed to at the bottom of the cell-culture dish is proportional to the concentration of NPs in the suspension. However, the concentration of NPs in suspension defi nes only the administered dose, and the above paradigm is strictly valid only when all NPs in the suspension have completely settled, in which case the delivered dose is equal to the administered dose. The ultimate fate of NPs in a fl uid is eventually dictated by its mass density, i.e., NPs will settle if their mass density is greater than that of the fl uid. The impact of NP size and mass density on transport has been known for a long time [26][27][28][29] : in general, sedimentation is dominant for large NPs of "higher" mass density, while diffusion dominates the transport for small NPs of "lower" mass density. The kinetics of a particle is quantifi ed by the diffusion coeffi cient (the Stokes-Einstein equation and the settling velocity, Stokes' law). [ 26 ] Depending on (i) the hydrodynamic radius of the NPs, (ii) the mass density difference between the particle and the fl uid, (iii) the concentration of NPs in the colloidal suspension, (iv) the total volume of the colloidal suspension administrated to the cell culture, and (v...

“…Despite the recent development of hypernuclear physics both in theory and experiment, the actual knowledge of the hyperon-nucleon (YN) interaction is limited and the amount of data available to define a realistic YN potential is far from being comparable to the NN case: the standard set employed in the modern hyperon-nucleon interactions comprises 35 selected Λp low energy scattering data [2] and a few YN data at higher energies, against the over 4000 NN data in the range 0÷350 MeV. Quite a variety of potential models involving hyperons exist, ranging from purely phenomenological ones [3] to models based on chiral effective field theory [4].…”

Abstract. We have adapted the non-symmetrized hyperspherical harmonics method (NSHH) in order to treat light hypernuclei. In the past the method has been applied in the atomic and nuclear context dealing with identical particle systems exclusively. We have generalized and optimized the formalism in presence of two different species of particles, namely nucleons and hyperons. Preliminary benchmark results with a modern realistic 2-body nucleon-hyperon interaction are provided.
