Resolving the negative effective neutrino mass parameter with cosmic birefringence

Kavli Affiliate: Toshiya Namikawa | Summary:The recent measurement of baryonic acoustic oscillations by the Dark Energy Spectroscopic Instrument reveals a mild tension with observations of the cosmic microwave background (CMB) within the standard $Λ$CDM cosmological model. This discrepancy leads to a preference for a total neutrino mass that is lower than the minimum value inferred […]

Synaptic plasticity of prefrontal long-range inhibition regulates cognitive flexibility

Kavli Affiliate: Vikaas Sohal | Authors: Xiyu Zhu, Lara L. Hagopian, Kira E. Wallquist and Vikaas Singh Sohal | Summary: While glutamatergic synaptic plasticity is believed to be a fundamental mechanism mediating learning, the behavioral significance of plasticity at cortical GABAergic synapses remains less well understood. Furthermore, despite recent discoveries of long-range projections from neocortical […]

Bayesian constraints on quark stars from multi-messenger observations

Kavli Affiliate: Renxin Xu | Summary:We perform a systematic Bayesian analysis of quark star equations of state under current multimessenger constraints, investigating the impact of prior assumptions and extreme-mass observations. Quark matter is modeled within an interacting MIT bag framework that consistently accommodates color-superconducting phases (2SC, 2SC+s, and CFL) and perturbative QCD corrections. We find […]

The diffuse supernova neutrino background: an update with modern population synthesis and core-collapse simulations

Kavli Affiliate: Shunsaku Horiuchi | Summary:We present a new, state-of-the-art computation of the Diffuse Supernova Neutrino Background (DSNB), where we use neutrino spectra from multi-dimensional, multi-second core collapse supernova simulations – including both neutron-star and black-hole forming collapses – and binary evolution effects from modern population synthesis codes. Large sets of numerical results are processed […]

Residual Matrix Transformers: Scaling the Size of the Residual Stream

Kavli Affiliate: Kinfai Mak | First 5 Authors: Brian Mak, Brian Mak, , , | Summary: The residual stream acts as a memory bus where transformer layers both store and access features (Elhage et al., 2021). We consider changing the mechanism for retrieving and storing information in the residual stream, and replace the residual stream […]
