Bone carvings (and other ivory substitutes) are common in the modern-day lucrative international ivory trade.Souvenirs for unknowing travelers and market shoppers can be made of non-biological material (plastic "ivory" beads) or skillfully crafted natural objects made to resemble something other than their true origin.Many of these items are receiv
One-Dimensional Mass-Spring Chains Supporting Elastic Waves with Non-Conventional Topology
There are two classes of phononic structures that can support elastic waves with non-conventional topology, namely intrinsic and extrinsic systems.The non-conventional topology of elastic wave results from breaking Shorts time reversal symmetry (T-symmetry) of wave propagation.In extrinsic systems, energy is injected into the phononic structure to
Targeted and explorative profiling of kallikrein proteases and global proteome biology of pancreatic ductal adenocarcinoma, chronic pancreatitis, and normal pancreas highlights disease-specific proteome remodelling
Pancreatic ductal adenocarcinoma (PDAC) represents one of the most aggressive and lethal malignancies worldwide with an urgent need for new diagnostic and therapeutic strategies.One major risk factor for PDAC is the pre-indication of chronic pancreatitis (CP), which represents highly inflammatory pancreatic tissue.Kallikreins (KLKs) are secreted se
