Recent concerns about underwater intruder attacks on ships in port and harbour infrastructure raised strong interests in detecting divers. This paper reviews current research and systems on diver detection using acoustic means and the factors affecting system performance. Previous published data on diver acoustic target strength is discussed and seem to be plausibly explained by considering the...

Affective priming (AP) is a well-established phenomenon in which performance to a valenced target is typically better when it is preceded by an affectively congruent prime than when it is preceded by an incongruent prime. Several studies have emphasized a strong similarity between AP and Stroop suggesting that both are driven by response interference. The present study investigated this hypothe...

Fish species can be identify using target strength (TS) model. The result of model compared with result from in situ measurement as benchmark. Selarboops (Oxeyescad) as commercial fish from South China Sea has been used. Lateral and dorsal X-ray of fish has been deployed to perform fish body and swim bladder morphology and then divided into a number of pieces for Kirchhoff-Ray Mode (KRM) model ...

A 200-kHz echosounder modified to digitize the envelope of the received echoes directly into a computer was used to measure the ex situ target strength ~TS! of live animals from the Hawaiian mesopelagic boundary community as a function of animal size, tilt and roll angle, and biological classification. Dorsal aspect TS ~in dB//1 m! at 200 kHz was related to the animal’s length: myctophid fish T...

MicroRNAs, or miRNAs, post-transcriptionally repress the expression of protein-coding genes. The human genome encodes over 1000 miRNA genes that collectively target the majority of messenger RNAs (mRNAs). Base pairing of the so-called miRNA 'seed' region with mRNAs identifies many thousands of putative targets. Evaluating the strength of the resulting mRNA repression remains challenging, but is...

Recent neuroimaging studies have shown that activity in lateral Heschl's gyrus covaries specifically with the strength of musical pitch. Pitch strength is important for the perceptual distinctiveness of an acoustic event, but in complex auditory scenes, the distinctiveness of an event also depends on its context. In this magnetoencephalography study, we evaluate how temporal context influences ...

To evaluate the effects of industrial by-products materials on the performance of porous concrete for plant growth, this study investigated the physical, strength, and freeze/thaw resistances of porous concrete for plant growth, prepared by replacing cement with blast furnace slag powder at 60% by weight, and replacing natural stone aggregates with coarse blast furnace slag aggregates at rates ...

Recognizing that value involves experiencing pleasure or pain is critical to understanding the psychology of value. But hedonic experience is not enough. I propose that it is also necessary to recognize that strength of engagement can contribute to experienced value through its contribution to the experience of motivational force--an experience of the intensity of the force of attraction to or ...
