Griffiths phases in infinite-dimensional, non-hierarchical modular networks

open access: yes, 2018
Griffiths phases (GPs), generated by the heterogeneities on modular networks, have recently been suggested to provide a mechanism, rid of fine parameter tuning, to explain the critical behavior of complex systems.

Elranatamab in Relapsed/Refractory Multiple Myeloma: Mechanisms, Clinical Evidence, and Emerging Perspectives

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Relapsed and refractory multiple myeloma (RRMM) remains associated with poor outcomes, particularly in patients exposed or refractory to proteasome inhibitors, immunomodulatory agents, and anti‐CD38 monoclonal antibodies. Targeting B‐cell maturation antigen (BCMA) has emerged as an effective therapeutic strategy, prompting the development of ...

Motives and barriers to blood donation among adults aged over 50 years: A qualitative analysis

open access: yesTransfusion Medicine, EarlyView.
Abstract Background Ageing populations will increase demand for blood‐products and donors who supply them. While blood collection agencies (BCAs) typically target younger people to expand supply, recruiting donors aged 50+ is also a potential solution. However, few studies focus exclusively on this group.

Coulomb effects in artificial molecules

open access: yes, 1996
We study the capacitance spectra of artificial molecules consisting of two and three coupled quantum dots from an extended Hubbard Hamiltonian model that takes into account quantum confinement, intra- and inter-dot Coulomb interaction and tunneling ...

Dose‐Dependent Effect of Plant Volatiles on the Oviposition Preference of the Corn Leafhopper Dalbulus maidis

open access: yesJournal of Applied Entomology, Volume 150, Issue 4, Page 497-505, May 2026.
ABSTRACT Maize (Zea mays L.) is a major annual crop cultivated worldwide. In the Americas, the corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae) is a key pest of this crop, causing direct damage to plants through phloem feeding and indirect damage by transmitting phytopathogens.

Partial wave analysis of the Dirac fermions scattered from Reissner - Nordstr\" om charged black holes [PDF]

open access: yes, 2016
The asymptotic form of Dirac spinors in the field of the Reissner-Nordstrom black hole are derived for the scattering states (with $E>mc^2$) obtaining the phase shifts of the partial wave analysis of Dirac fermions scattered from charged black holes. The

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Análise do comportamento do riacho Bacuri por meio da curva cota-volume

open access: yesNovos Cadernos NAEA, 2023
Durante o processo de urbanização, a população de Imperatriz-MA ocupou as áreas de margem do riacho Bacuri, que diariamente recebe lixo e esgoto doméstico em seu leito, o qual, também, por falta de manutenção, fica parcialmente obstruído, e sofre a ...
