Germanium Negative Capacitance Field Effect Transistors: Impacts of Zr Composition in Hf1−x Zr x O2

Nanoscale Research Letters, 2019
Germanium (Ge) negative capacitance field-effect transistors (NCFETs) with various Zr compositions in Hf1−x Zr x O2 (x = 0.33, 0.48, and 0.67) are fabricated and characterized. For each Zr composition, the NCFET exhibits the sudden drop in some points of

Phonon Band Gaps

Journal de Physique I, 1997
We present structures, based on rods, that exhibit phonon band gaps. Structures based on rods made out of segments of different materials have very large gaps or multiple gaps. For homogeneous cylinders smaller gaps exist. Possible applications are discussed.

Upacicalcet: A Novel Intravenous Calcimimetic Agent for Patients Undergoing Hemodialysis With Secondary Hyperparathyroidism

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.

Adjunctive Therapeutic Plasma Exchange in Refractory Adult‐Onset Still's Disease Complicated by Secondary Macrophage Activation Syndrome: A Single‐Center Experience

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.
