There is increasing evidence of indirect effects of hunting on populations. In species with sexually selected infanticide (SSI), hunting may decrease juvenile survival by increasing male turnover. We aimed to evaluate the relative importance of direct and indirect effects of hunting via SSI on the population dynamics of the Scandinavian brown bear (Ursus arctos). We performed prospective and re...

To investigate early effects of beta-amyloid (Ab) on neuronal function, elderly normal controls (NCs, age range 58--97) were scanned with Pittsburgh Compound-B (PIB) positron emission tomography (a measure of Ab) as well as functional magnetic resonance imaging (a measure of brain activation) while performing an episodic memory--encoding task of natural scenes (also performed by young NCs; age ...

Hunting is a flutter associated with the synchronous speed that gives rise to the gyro drifting errors and may cause objectionable time-displacement errors in video head wheel drives and other precision scanning systems. In this paper, dynamic characteristics of permanent Magnet hysteresis motors are presented and hunting is explained. New damping techniques have been developed using optimi...

Hedgehogs held a special place in ancient Egyptian life like many other desert- and marsh-dwelling animals. Their natural defensive qualities were admired by Egyptians their bodily parts, notably hardened spines, used as ingredients medico-magical prescriptions. In tomb reliefs of the late 3rd Millennium BCE, hedgehogs are represented being carried alive offering bearers or background participa...

To investigate early effects of beta-amyloid (Aβ) on neuronal function, elderly normal controls (NCs, age range 58-97) were scanned with Pittsburgh Compound-B (PIB) positron emission tomography (a measure of Aβ) as well as functional magnetic resonance imaging (a measure of brain activation) while performing an episodic memory-encoding task of natural scenes (also performed by young NCs; age ra...

Various species of the family Phalangeridae, commonly known as cuscus (also known as kuskus, or kusu locally in central Maluku), may have been an important terrestrial meat resource in traditional subsistence diets throughout Maluku. Only a few groups continue to hunt cuscus today. Traditional and modern hunting techniques are practiced, and the cuscus meat is highly valued for its flavor, nutr...

Numerous studies have shown that the gist in photorealistic pictures of scenes is extracted after very short presentation times. So far, the investigation of gist extraction has been limited to pictures of scenes. The present study investigated whether the gist in pictures of causal systems, which are typically used as instructional material, is extracted as fast as the gist in pictures of scen...

Torralba (Visual Neuroscience, 26, 123-131, 2009) showed that, if the resolution of images of scenes were reduced to the information present in very small "thumbnail images," those scenes could still be recognized. The objects in those degraded scenes could be identified, even though it would be impossible to identify them if they were removed from the scene context. Can tiny and/or degraded sc...

Recent studies have found that when viewing real world social scenes, observers look preferentially at the eyes of people relative to other scene regions (Birmingham et al., in press (a); Birmingham et al., in press (b); Smilek, Birmingham, Cameron, Bischof & Kingstone, 2006). This preference occurs in scenes displaying a variety of social situations (e.g. one or three people performing various...

In mollusks, statocyst receptor cells (SRCs) interact with each other forming a neural network; their activity is determined by both the animal's orientation in the gravitational field and multimodal inputs. These two facts suggest that the function of the statocysts is not limited to sensing the animal's orientation. We studied the role of the statocysts in the organization of search motion du...
