Dynamic Penetration Process of Torpedo Anchors into Sand Foundation

open access: yesJournal of Marine Science and Engineering, 2022
Torpedo anchors are a new type of anchoring system in deepwater that is much more economical than conventional anchoring methods. The dynamic penetration process is vitally important to the installation of torpedo anchors.

Operational Simulation and Efficiency Analysis of Torpedo Electromagnetic Fuse Jammer

open access: yes水下无人系统学报, 2022
Torpedo electromagnetic fuse jammers are a type of weapon equipment used against wake-homing torpedoes in the wake area of surface ships. The operational parameters of the jammer determine its countering effectiveness.

Conductance increases produced by bath application of cholinergic agonists to Electrophorus electroplaques [PDF]

open access: yes, 1975
When solutions containing agonists are applied to the innervated face of an Electrophorus electroplaque, the membrane's conductance increases. The agonist-induced conductance is increased at more negative membrane potentials.

Improved PSO Algorithm to Defend against Acoustic Homing Torpedoes Using an Acoustic Decoy of a Submarine

open access: yes水下无人系统学报, 2023
A submarine that uses a single self-propelled acoustic decoy to defend against an S-type maneuver acoustic homing torpedo must immediately implement a defensive counterplan that achieves the maximum distance between the torpedo and itself . In this study,

Simulation of Torpedo Combustion Chamber Thermal-Fluid-Solid Coupling Heat Transfer

open access: yes水下无人系统学报, 2023
To improve the cooling heat transfer performance of torpedo combustion chambers, a numerical simulation of the thermal-fluid-solid cooling heat transfer process in a torpedo combustion chamber was performed based on the thermal-fluid-solid coupling ...

Tris+/Na+ permeability ratios of nicotinic acetylcholine receptors are reduced by mutations near the intracellular end of the M2 region [PDF]

open access: yes, 1992
Tris+/Na+ permeability ratios were measured from shifts in the biionic reversal potentials of the macroscopic ACh-induced currents for 3 wild- type (WT), 1 hybrid, 2 subunit-deficient, and 25 mutant nicotinic receptors expressed in Xenopus oocytes.

Functional Stoichiometry at the Nicotinic Receptor. The Photon Cross Section for Phase 1 Corresponds to Two Bis-Q Molecules per Channel [PDF]

open access: yes, 1982
These experiments examine changes in the agonist-induced conductance that occur when the agonist-receptor complex is perturbed. Voltage-clamped Electrophorus electroplaques are exposed to the photoisomerizable agonist trans-Bis-Q A 1-µs laser flash ...
