This article details the preliminary design and testing of a Resetting Anchor/Antenna Tether Mechanism (RAATM) for an autonomous underwater vehicle (AUV).The CHROMIUM proposed mechanism is intended to enable an AUV to secure itself to the seabed, ascend, descend, transmit and receive signals via the tether, retract the anchor, and re-anchor again a
Germ cell tumors in infants are most Oven Shelf Support Rack Screw frequently extragonadal, benign, and amenable to surgical resection.An unusual feature of germ cell tumors is the potential coexistence of malignant with benign disease which makes it possible for patients with incompletely resected tumors to experience either a benign or malignant
Underwater vehicles have capacity limits for control inputs, within which their time-optimal trajectories (TOTs) can be formulated.In this study, the fastest trajectory for the depth control of a hybrid underwater glider (HUG) was found using buoyancy engines and propellers individually, and the decoupled heave dynamics of the HUG were defined usin
A 56-year-old man was referred to our hospital about 48 h after sudden onset of painless central visual loss in his right eye (OD) on a winter morning.He had a more than 25-year history of systemic hypertension and smoking.Funduscopic observation showed striated retinal whitening in the HALVA VANILLA macular region, faint cotton-wool patches around
