Squid are the largest jet propellers in nature as adults, but as paralarvae they are some of the smallest, faced with the inherent inefficiency of jet propulsion at a low Reynolds number. In this study we describe the behavior and kinematics of locomotion in 1 mm paralarvae of Dosidicus gigas, the smallest squid yet studied. They swim with hop-and-sink behavior and can engage in fast jets by re...

Upon hatching, the Hawaiian squid Euprymna scolopes is rapidly colonized by its symbiotic partner, the bioluminescent marine bacterium Vibrio fischeri . Vibrio fischeri cells present in the seawater enter the light organ of juvenile squid in a process that requires bacterial motility. In this study, we investigated the role chemotaxis may play in establishing this symbiotic colonization. Pre...

We compare the performance of a chip-scale atomic magnetometer CSAM with that of a superconducting quantum interference device SQUID sensor in two biomedical applications. Magnetocardiograms MCGs of healthy human subjects were measured simultaneously by a CSAM and a multichannel SQUID sensor in a magnetically shielded room. The typical features of MCGs are resolved by the CSAM, matching the SQU...

Trypsin inhibitor was purified from the hepatopancreas of squid (Todarodes pacificus). The final inhibitor preparation was nearly homogeneous by SDS-PAGE with an estimated molecular weight of approximately 6300. The squid trypsin inhibitor was acid- and heat-stable, and active against trypsins from the pyloric ceca of starfish (Asterias amurensis) and saury (Cololabis saira) and porcine pancrea...

A superconducting quantum interference device (SQUID) comprising 0- and $\pi$-Josephson junctions (JJs), called $\pi$-SQUID, is studied by the resistively shunted junction model. The $\pi$-SQUID shows half-integer Shapiro-steps (SS) under microwave irradiation at voltage $V$ = $(\hbar/2e)\Omega (n/2)$, with angular frequency $\Omega$ $n$/2 in addition to integer $n$. We show that can be a $\pi$...

Assessment of a patient with probable allergic contact dermatitis caused by a tattoo ink is a difficult task, because regulations regarding the substances used as tattoo inks continue to be limited, and ink component information is difficult to access (1). Moreover, in most cases, patch testing with the culprit ink is often of little benefit. We report a case in whom patch testing with the ink ...

We propose an extension of the cellular Yule-Nielsen spectral Neugebauer model accounting for ink spreading of each ink within each subdomain. Characterization of the ink spreading within a given subdomain is performed by fitting the mid-range weights of subdomain node reflectances with the goal of minimizing the sum of square differences between predicted and measured mid-range reflectances. W...

The Yule–Nielsen modified spectral Neugebauer model YNSN) enhanced for accounting for ink spreading in the different nk superposition conditions requires a spectrophotometer to meaure the reflectances of halftone calibration patches in order to comute the ink spreading curves mapping nominal ink surface coverge to effective ink surface coverage. Inst...

The environmental and biotic conditions affecting fisheries for cephalopods are only partially understood. A problem central to this is how climate change may influence population movements by altering the availability of thermal resources. In this study we investigate the links between climate and sea-temperature changes and squid arrival time off southwestern England over a 20-year period. We...
