Kavli Affiliate: Seth Shipman | Authors: Jihoon Han and Seth Shipman | Summary: Here, we introduce Detectrons, modular biosensors that couples programmable toehold switches with retron-mediated reverse transcription to transduce RNA inputs into unique DNA barcodes. The ability to convert dynamic RNA signals into durable DNA records within living cells unlocks powerful new modes of […]
Kavli Affiliate: George Efstathiou | Summary:Measurements from the Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission 2 (ARCADE-2) reveal a strong radio background in the GHz frequency range. Since the cosmological 21-cm signal is measured relative to the background radiation temperature, the presence of a radio excess can significantly alter its characteristics. Previous studies have […]
Kavli Affiliate: Salman Habib | Summary:Quantum low-density parity-check (QLDPC) codes are a leading approach to quantum error correction, yet conventional belief propagation (BP) decoders often perform poorly, primarily due to non-convergence exacerbated by stabilizer constraints, which induce short cycles and degeneracy. We propose two scheduling variants, sequential check node scheduling (SCNS) and sequential variable node […]
Kavli Affiliate: Wendy Freedman | Summary:We examine the multi-wavelength period-luminosity-color relations for Cepheid variables in the Large and Small magellanic Clouds and the Milky Way. From first-principles stellar physics, the luminosity of a Cepheid is determined by its radius and surface temperature, yielding a fundamental PLC relation whose observational proxies are pulsation period and intrinsic […]
Kavli Affiliate: Yasunori Nomura | Summary:Recent developments in gravitational path integrals indicate that the nonperturbative physical Hilbert space of a closed universe is one-dimensional within each superselection sector. This raises a basic puzzle: how can a unique quantum-gravity state give rise to semiclassical physics, measurement outcomes, and classical probabilities? In this paper, we develop a […]

Kavli Affiliate: Avi Shporer | Summary:We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of $1.081pm0.047$ R$_textJ$ and a mass of $4.78_-0.37^+0.40$ M$_textJ$ on a long-period ($180.52791pm0.00038$ day), moderately eccentric ($e=0.308pm0.011$) orbit transiting a bright (V=$10.230pm0.020$ mag) metal rich ([Fe/H]=$0.33pm0.09$, ‘dex’) F6V-F7V type host star. The planet was […]

Kavli Affiliate: Grace Xing | Summary:This brief report examines the influence of Ga/N flux conditions on Mn incorporation in GaN. Mn-doped GaN layers were grown at 680$^circ$C by molecular beam epitaxy on a Ga-polar GaN(0001) template substrate under Ga-rich, N-rich, and no-flux conditions (i.e., Mn $δ$ doping). Mn incorporation was highest under N-rich condition, lowest […]
