Here we report bipedal movement with a hydrostatic skeleton. Two species of octopus walk on two alternating arms using a rolling gait and appear to use the remaining six arms for camouflage. Octopus marginatus resembles a coconut, and Octopus (Abdopus) aculeatus, a clump of floating algae. Using underwater video, we analyzed the kinematics of their strides. Each arm was on the sand for more tha...

The objective was to evaluate nystagmus intensity and direction (NID) during bow and lean test (BLT) in subjects suffering from idiopathic lateral semicircular canal benign paroxysmal positional vertigo (LSC-BPPV), in order to differentiate between the geotropic and the apogeotropic form and to determine the affected ear before using classic diagnostic procedures. The BLT was performed in 32 su...

Semiconductor companies have increasingly adopted a methodology that starts with a system-level design specification in C/C++/SystemC. This model is extensively simulated to ensure correct functionality and performance. Later, a Register Transfer Level (RTL) implementation is created in Verilog, either manually by a designer or automatically by a high-level synthesis tool. It is essential to ch...

Unmanned space servicing requires an ability to capture a free-floating satellite, replace a module and deploy the satellite using a robotic arm. As direct teleoperation from the ground is not possible due to limitations of the communication link (delay, bandwidth and intermittence) the servicers will therefore have to operate with a certain degree of autonomy. The need for autonomy is particul...

The submerged platform or Morris water escape task is widely used to study genetic variation in spatial learning and memory, but interpretation is sometimes difficult because of wall hugging, jumping off the platform, floating or non-spatial swim strategies. We modified the task by introducing four wide arms into the circular tank and adding features that reduced, eliminated, or compensated for...

This letter presents a compliant feedback controller of an arm-equipped spacecraft, which does not enforce requirements on the spacecraft position and attitude. The is applicable to pre-contact, contact, post-contact phases robotic operation. In contrast conventional floating-base strategies, eliminates instability system during steady thus can be used in realistic applications. uses external-i...

nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. psychological factors such as catastrophic thinking, symptoms of d...

Floating particles often appear during the Czochralski (CZ) growth of β-Ga2O3 in Ir crucible, thereby impeding seeding process. Identifying floating nanoparticles and then inhibiting or removing them is critical for growing high-quality single crystals. We grew crystals containing using CZ method. It indicated that were composed with a face-centered cubic (fcc) structure. In addition, β-Ga2O3/I...

This paper describes how to implement efficient FIR filters on ARM Cortex-M3 microprocessors. Two multiply-accumulate instructions are discussed: MLA – multiply with accumulate, using 32-bit operands and producing a 32-bit result, and SMLAL – signed multiply with accumulate, using 32-bit operands and producing a 64-bit result. There are advantages and disadvantages for each instruction. It is p...
