A Biophysical Approach to the Design of Networks of Communication Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Inspired by the growth dynamics of the protist Physarum polycephalum, we employ a formalism that describes adaptive, incompressible Hagen‐Poiseuille flows on channel networks to identify graphs connecting different nodes within Euclidean space. These graphs are either suboptimal or optimal relative to their length.

Hidden sectors in string theory: kinetic mixings, fifth forces and quintessence

Journal of High Energy Physics, 2019
Light moduli fields in string compactifications can have interesting implications for particle physics and cosmology. Fifth force bounds impose stringent constraints on the interactions of such moduli with the visible sector.

New Signal for Universal Extra Dimensions [PDF]

, 2002
In the universal extra dimensions (UED) scenario, the tree level masses of the first level Kaluza-Klein (KK) excitations of Standard Model particles are essentially degenerate. Radiative corrections will, however, lift this degeneracy, allowing the first

The DNA of Calabi–Yau Hypersurfaces

Fortschritte der Physik, EarlyView.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Mentoring matters to early‐career veterinarians' confidence, clinical growth and career retention: A qualitative interview study

Veterinary Record, EarlyView.
Abstract Background Veterinarians in clinical practice, especially early‐career veterinarians and those identifying as women, have higher levels of negative mental health outcomes compared to the general population. Partnering with a mentor can mitigate some of the work‐related challenges that may contribute to poor mental health and career attrition ...

Collider and Dark Matter Searches in Models with Mixed Modulus-Anomaly Mediated SUSY Breaking [PDF]

, 2006
We investigate the phenomenology of supersymmetric models where moduli fields and the Weyl anomaly make comparable contributions to SUSY breaking effects in the observable sector of fields.

AUGURAL TERRITORIES: On the Prophetic Organizing of the Mid‐range

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article I introduce the concept of augural territories to theorize the urbanism that emerged during pandemic lockdowns. I draw on ethnographic research in Madrid to examine how community‐based responses—including mutual aid networks, food pantries and neighbourhood associations—disrupted the spatial and temporal logics of territorial ...

A Hybrid Model of Neutrino Masses and Oscillations: Bulk Neutrinos in the Split-Fermion Scenario [PDF]

, 2006
Higher-dimensional models of neutrino physics with one or more right-handed neutrinos in the bulk have attracted considerable attention in recent years.

Surprise and the singular plural

American Ethnologist, EarlyView.
Abstract Bodymind diversity, disability scholars argue, contributes to community and to ideals of human flourishing. Phenomenologists like Nancy and Arendt, meanwhile, foreground our human pluralism. But what does it mean to inhabit (and invent) a plural “we” across significant bodily difference? And why is the experience of surprise important to it? A

Haunted by Houses: Built and Lived Absences in a Transnational Mexican Community

Anthropology of Consciousness, EarlyView.
ABSTRACT Globally, millions of migrants have sent money home to build a house. In early phases of migration, remittance houses are aspirational objects that materialize the continuous belonging of migrants to a community. In later stages, experiences of loss, estrangement, deportation, and death increasingly challenge these attachments.
