We present a dual isotope magneto-optical trap (MOT), simultaneous sub-Doppler laser cooling, and magnetic trapping of a spin-polarized K-K Bose-Fermi mixture realized in a single-chamber setup with an unenriched potassium dispenser as the source of atoms. We are able to magnetically confine more than 2.2 × 10 fermions ( = 9/2 , = 9/2) and 1.4 × 10 bosons ( = 2 , = 2) with a lifetime exceeding 1.2 s. For this work, we have developed a versatile laser tailored for sub-Doppler cooling of all naturally occurring potassium isotopes and their mixtures. This laser system incorporates innovative features, such as the capability to select an isotope by activating or deactivating specific acousto-optic modulators that control the light seeding tapered amplifiers. Switching between isotopes takes ∼1 µs without any mechanical adjustment of the components.

In this article, we comment on the article by Cheng published in recently. Posthepatectomy liver failure (PHLF) remains a leading cause of hepatectomy-related mortality and can be evaluated according to liver reserve function. Liver stiffness (LS) measured by ultrasonic elastography and spleen area demonstrate a strong correlation with hepatic proliferation, fibrosis, and portal vein congestion, thus indirectly reflecting liver reserve function.

The capture of magnetic nanoparticles (MNPs) is essential in the separation and detection of MNPs for applications such as magnetic biosensing. The sensitivity of magnetic biosensors inherently depends upon the distribution of captured MNPs within the sensing area. We previously demonstrated that the distribution of MNPs captured from evaporating droplets by ferromagnetic antidot nanostructures can be controlled via an external magnetic field.

Unlabelled: Due to the increasing number of people working at computers in professional settings, the incidence of lumbar disc herniation is increasing.
Background/objectives: The early diagnosis and treatment of lumbar disc herniation is much more likely to yield favorable results, allowing the hernia to be treated before it develops further. The aim of this study was to classify lumbar disc herniations in a computer-aided, fully automated manner using magnetic resonance images (MRIs).

Persistent primitive olfactory arteries (PPOAs) are a rare variant of the anterior cerebral artery (ACA). Cerebral aneurysms may arise in the PPOA; most are saccular and on the unilateral PPOA. We report a 66-year-old male with bilateral PPOAs and a fusiform aneurysm on the left side detected at a health check-up.
