Abstract Measurement of the largest angular scale ( ℓ < 30) features cosmic microwave background (CMB) polarization is a powerful way to constrain optical depth reionization and search for signature inflation through detection primordial B -modes. We present an analysis maps covering 73.6% sky made from 40 GHz channel Cosmology Large Angular Scale Surveyor (CLASS) 2016 August 2022 May. Taking advantage measurement stability enabled by front-end modulation excellent conditions Atacama...

The overall efficiency and image uniformity are important criteria for augmented reality display. conventional in-coupling grating design intending to improve only the first-order diffraction without considering multiple interactions with diffracted light in waveguide is insufficient. In this work, back-coupling loss (BCL) on surface relief grating, power of arriving at out-coupling over that incident (denoted as optical waveguide, OEW) introduced grating. A simple effective method increase...
Electromagnetic radiation from the cusp region of superconducting cosmic strings leads to a radio excess in photon spectrum early universe and can produce deep absorption feature global 21 cm signal before epoch reionization. We study constraints on parameter space which be derived by demanding that is not larger amplitude than what has recently been reported EDGES collaboration. find previously unconstrained high current, low tension would too strong an feature, are thus ruled out non-detection.
We present measurements of large-scale cosmic microwave background (CMB) E-mode polarization from the Cosmology Large Angular Scale Surveyor (CLASS) 90 GHz data. Using 115 det-yr observations collected through 2024 with a variable-delay modulator, we achieved sensitivity $78\,\mathrm{\mu K\,arcmin}$, comparable to Planck at similar frequencies (100 and 143 GHz). The analysis demonstrates effective mitigation systematic errors addresses challenges large-angular-scale power recovery posed by...
Abstract The Cosmology Large Angular Scale Surveyor (CLASS) is a telescope array that observes the cosmic microwave background over 75% of sky from Atacama Desert, Chile, at frequency bands centered near 40, 90, 150, and 220 GHz. This paper describes CLASS data pipeline maps for 40 GHz observations conducted 2016 August to 2022 May. We demonstrate how well survey strategy, with rapid (∼10 Hz) front-end modulation, recovers large-scale Galactic polarization signal ground: mapping transfer...
In this paper, we explore the power of cosmic microwave background (CMB) polarization (E-mode) data to corroborate four potential anomalies in CMB temperature data: lack large angular-scale correlations, alignment quadrupole and octupole (Q-O), point-parity asymmetry, hemispherical asymmetry. We use simulations with noise representative three experiments -- Planck satellite, Cosmology Large Angular Scale Surveyor (CLASS), LiteBIRD satellite test how current future constrain anomalies. find...
Comprehensive Summary Deep ultraviolet (UV) photodetectors have important applications in the industrial and military fields. However, little research has been reported on organic phototransistors (OPTs) deep range. Here, a novel semiconductor containing small torsion angle low π‐conjugation 2,2':5',2”‐terthiophene groups, oF‐PTTTP, is designed synthesized, which exhibits high carrier mobility unique response. Accordingly, an OPT based oF‐PTTTP single crystal shows responsivity to deep‐UV...

First, global Moran’s I is employed to check for autocorrelation development. The results demonstrate a positive correlation between local province and neighboring during sample period. Then, we validate accuracy performance Durbin model by comparing it with two other models: error autoregression. Wald Likelihood Ratio tests confirmed...
Abstract Background Tricuspid regurgitation (TR) is common and related to poor prognosis in patients after left ventricular assist device (LVAD) implantation. The concomitant tricuspid valve surgery (TVS) at the time of LVAD implantation on short long-term outcomes are controversial current evidence. Methods This a single-center, observational, retrospective study. We enrolled with moderate-to-severe TR who received implantations from 2009 2020. Postoperative right failure (RVF), (RVAD) use,...
