In the title compound, C(20)H(18)N(2)O(3)S, the dihedral angle between the central benzene ring and the amide group is 24.1 (3)° and that between this ring and the aromatic ring of the tolyl group is 68.2 (16)°. In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds into a linear chain running along [100]. Weak C-H⋯O contacts also occur. Extensive weak π-π inter-actions exist fr...

We report studies of the surface reconstructions for both the Ga-face and the N-face of wurtzite GaN films grown using molecular beam epitaxy. Nface reconstructions are primarily adatom-on-adlayer structures which can be formed by room temperature sub-monolayer Ga deposition. These structures undergo reversible order-disorder phase transitions to 1×1 in the temperature range of 200–300 C. Ga-fa...

The human face is central to our identity. It plays an essential role in everyday interaction, communication and other routine activities. Thus, face detection and tracking algorithms are of great importance for human-machine interaction. It is an extensively studied field and a large body of research has been done. This paper gives a a broad overview of basic principles and some representative...

Two new Mycetophilidae species, Neurateliajabalmoussae sp. n. and Neurateliasalmelai sp. n. are described on the basis of material collected from Lebanon, Estonia and Finland. Detailed figures of male terminalia and photographs of general facies are provided along with discussions of their morphological distinction from sibling species. For the first time molecular characters are used to distin...

It has been established that successful ignoring of irrelevant distractors depends on the extent to which the current task loads attention. However, the previous load studies have typically employed neutral distractor stimuli (e.g., letters). In the experiments reported here, we examined whether the perception of irrelevant distractor faces would show the same effects. We manipulated attentiona...

It has been shown that a person's position in a group influences how that person is evaluated, with people in the middle perceived as more important than people on the fringe of a group. Four experiments examined whether the position of a face, in a line of five faces, influenced facial attractiveness. The middle position influenced the perceived attractiveness of the target face but the direct...

The face recognition task we perform [corrected] most often in everyday experience is the identification of people with whom we are familiar. However, because of logistical challenges, most studies focus on unfamiliar-face recognition, wherein subjects are asked to match or remember images of unfamiliar people's faces. Here we explore the importance of two facial attributes -shape and surface r...

Looking at another person's facial expression of emotion can trigger the same neural processes involved in producing the expression, and such responses play a functional role in emotion recognition. Disrupting individuals' facial action, for example, interferes with verbal emotion recognition tasks. We tested the hypothesis that facial responses also play a functional role in the perceptual pro...

People believe they see emotion written on the faces of other people. In an instant, simple facial actions are transformed into information about another's emotional state. The present research examined whether a perceiver unknowingly contributes to emotion perception with emotion word knowledge. We present 2 studies that together support a role for emotion concepts in the formation of visual p...

Recognition of the identity of familiar faces in conditions with poor visibility or over large changes in head angle, lighting and partial occlusion is far more accurate than recognition of unfamiliar faces in similar conditions. Here we used a visual search paradigm to test if one class of social cues transmitted by faces-direction of another's attention as conveyed by gaze direction and head ...
