Spectra from two decades of zonal current data at $$\sim $$ 4000 m in the central and western equatorial Indian Ocean show a shift dominant frequencies west to east. The 120–180-day period is stronger 77 $$^\circ E, 60–120-day 83 30–90-day 93 E. weakening lower near eastern boundary can be explained using theoretical ray paths Kelvin waves reflected Rossby waves. wave forced by winds reflects a...

BACKGROUND Deep penetrating nevus is a recently described variant of melanocytic nevi with clinical and histopathological features that may be confused with malignant melanoma, blue nevus, pigmented Spitz nevus, or congenital melanocytic nevus. We report a case with linear arrangement of multiple deep penetrating nevi. To our knowledge, such presentation has never been reported in the literatur...

Coastal karst formations may remain unexplored by the global marine scientific research community. Knowledge provided fishermen coupled with on karstic prompted us to explore geomorphometric and physicochemical features of a submerged blue hole in large tropical estuary Chetumal Bay southeastern coast Yucatán Peninsula, Mexico. Differently from well-known literature cenotes no references are ma...

We deployed two wavelength calibrators based on laser frequency combs ("astro-combs") at an astronomical telescope. One astro-comb operated over a 100 nm band in the deep red (∼ 800 nm) and a second operated over a 20 nm band in the blue (∼ 400 nm). We used these red and blue astro-combs to calibrate a high-resolution astrophysical spectrograph integrated with a 1.5 m telescope, and demonstrate...

The device physics and electro-optical properties of emerging liquid crystal displays (LCDs) based on the Kerr effect are investigated. With a voltage applied, both blue phase and polymer-stabilized blue phase exhibit a fascinating isotropic-toanisotropic transition. We have developed a numerical model to understand the underlying device physics in order to optimize device performance. The oper...

Dermal melanocytosis is characterized by the presence of ectopic melanocytes in the dermis. The most common forms include the Mongolian spot, blue nevus, nevus of Ota, and nevus of Ito. Some types of dermal melanocytosis do not fit into any of these morphologic categories, however. Our case demonstrated an extensive amount of uniform deep blue patches of nevi with unilateral distribution on the...

Blue whales are little studied, face significant anthropogenic threats and within the Northern Indian Ocean, have a restricted range, making them an archetype for conservation needs of megafauna around the world. We studied feeding behavior of blue whales using dietary DNA metabarcoding of fecal samples. While globally blue whale populations feed predominantly on Euphausiidae, 87% of prey DNA a...
