Severe, Symptomatic Hypercalcemia Secondary to PTH-secreting Pancreatoblastoma.

Hypercalcemia may be induced by a variety of etiologies, most commonly primary hyperparathyroidism. Although primary hyperparathyroidism represents a relatively common endocrinological disorder, ectopic PTH secretion is a rare entity that is less well described in literature. We describe the first case to our knowledge of severe, symptomatic hypercalcemia found to be secondary to a PTH-secreting pancreatoblastoma.

Lake shape and the characteristics of migration behavior modify Atlantic salmon smolt migration success through lakes.

Migration is a high-risk behavior. For the Atlantic salmon, Salmo salar, migrating from its river nursery area to marine feeding grounds, the magnitude of risk varies with habitat type. Passage through lakes, in particular, is associated with low rates of migration success.

Which adults aged 65 and older are at low-risk for cervical spine injuries after low-level falls?

Objectives: The population is aging and falls are a common reason for emergency department visits. Appropriate imaging in this population is important. The objectives of this study were to estimate the prevalence of cervical spine injury and identify factors associated with cervical spine injuries in adults ≥ 65 years after low-level falls.

Scalable Atomic Arrays for Spin-Based Quantum Computers in Silicon.

Semiconductor spin qubits combine excellent quantum performance with the prospect of manufacturing quantum devices using industry-standard metal-oxide-semiconductor (MOS) processes. This applies also to ion-implanted donor spins, which further afford exceptional coherence times and large Hilbert space dimension in their nuclear spin. Here multiple strategies are demonstrated and integrated to manufacture scale-up donor-based quantum computers.

Structural Uncertainty Due to Fault Timing: A Multimodel Case Study from the Perth Basin.

Faults can fundamentally change a groundwater flow regime and represent a major source of uncertainty in groundwater studies. Much research has been devoted to uncertainty around their location and their barrier-conduit behavior. However, fault timing is one aspect of fault uncertainty that appears to be somewhat overlooked.
