Swampland constraints on 5d N $$ \mathcal{N} $$ = 1 supergravity
We propose Swampland constraints on consistent 5-dimensional N $$ \mathcal{N} $$ = 1 supergravity theories. We focus on a special class of BPS magnetic monopole strings which arise in gravitational theories.

A comment on effective field theories of flux vacua [PDF]
We discuss some basic aspects of effective field theory applied to supergravity theories which arise in the low-energy limit of string theory. Our discussion is particularly relevant to the effective field theories of no-scale supergravities that break supersymmetry, including those that appear in constructing de Sitter solutions of string theory.

Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...

Spin-charge separation for paired Dirac fermions in (1 + 1) dimensions
We study Dirac fermions at finite density coupled to a complex pairing field assumed to obey scalar field theory with quartic self-repulsion. The bulk of our work develops the mathematics that elucidates the propagation of fermionic excitations in such ...

Recursion in the classical limit and the neutron-star Compton amplitude
We study the compatibility of recursive techniques with the classical limit of scattering amplitudes through the construction of the classical Compton amplitude for general spinning compact objects.

Making tau amyloid models in vitro: a crucial and underestimated challenge
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

T T ¯ $$ T\overline{T} $$ -deformation and long range spin chains
We point out that two classes of deformations of integrable models, developed completely independently, have deep connections and share the same algebraic origin. One class includes the T T ¯ $$ T\overline{T} $$ -deformation of 1+1 dimensional integrable

Late time acceleration in Palatini gravity
We investigate the effect of the quadratic correction αR 2 and non-minimal coupling ξϕ 2 R on a quintessence model with an exponential potential V(ϕ) = M 4exp(−λϕ) in the Palatini formulation of gravity.

Effective Lagrangians for Scalar Fields and Finite Size Effects in Field Theory [PDF]
We discuss the approach of effective field theory on a d-dimensional Euclidean space in a scalar theory with two different mass scales in the presence of flat surfaces. Then considering Dirichlet and Neumann boundary conditions, we implement the renormalization program in the lambda phi^{4} theory in a region bounded by two parallel hyperplanes in the ...

The power of microRNA regulation—insights into immunity and metabolism
MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...
