Quantum computing is expected to provide an exponential speedup in machine learning. However, optimizing the data loading process, commonly referred to as "quantum data embedding," to maximize classification performance remains a critical challenge. In this Letter, we propose a neural quantum embedding (NQE) technique based on deterministic quantum computation with one qubit (DQC1).

We investigate the quasiparticles of a single nodal ring semimetal SrAs_{3} through axis-resolved magneto-optical measurements. We observe three types of Landau levels scaling as ϵ∼sqrt[B], ϵ∼B^{2/3}, and ϵ∼B that correspond to Dirac, semi-Dirac, and classical fermions, respectively. Through theoretical analysis, we identify the distinct origins of these three types of fermions present within the nodal ring.

Magnetic heat capacity measurements of a high-quality single crystal of the dipole-octupole pyrochlore Ce_{2}Hf_{2}O_{7} down to a temperature of T=0.02 K are reported. These show a two-peaked structure, with a Schottky-like peak at T_{1}∼0.

Ankylosing spondylitis (AS) is a chronic inflammatory spondyloarthropathy that predominantly affects the axial skeleton. While hallmark features such as sacroiliitis and syndesmophytes are well recognized, the presence of mediastinal masses may pose a diagnostic dilemma and raise concerns for malignancy or atypical infection. We report a middle-aged man in the fifth decade of life with longstanding untreated AS presenting with progressive quadriparesis.

Background: Cardiac biomarkers are important components for diagnosing perioperative myocardial infarction (MI). Efforts to detect MI by biomarker-release only faced heavy criticism, because cardiac biomarker-release has also been observed in situations that are not always related to cell death (e.g.
