Faces each have distinct pigmentation as well as shape, which suggests that both cues may play a role in the perception of faces. However, there is a common implicit assumption that pigmentation cues are relatively unimportant, and so the role pigmentation plays in face perception has gone largely unexplored. This thesis is a systematic investigation of the role of pigmentation in face recognit...

Elevated atmospheric CO2 can result in larger plants returning greater amounts of residue to the soil. However, the effects of elevated CO2 on carbon (C) and nitrogen (N) cycling for different soybean varieties have not been examined. Aboveground residue of eight soybean [Glycine max (L.) Merr.] varieties was collected from a field study where crops had been grown under two different atmospheri...

Biometrics deals with identifying individuals with the help of their biological (physiological and behavioral) data. The security of biometric systems has however been questioned and previous studies have shown that they can be fooled with artificial artifacts. Also biometric recognition systems face challenges arising from intra-class variations and attacks upon template databases. To tackle s...

Face detection is fundamental for several important applications, such as, face recognition and human-computer interaction. This paper details a novel hierarchical face detector which combines motion, colour and late fusion. Motion segmentation is employed to eliminate background clutter and to reduce the initial search space. Subsequently, skin segmentation is used to determine a candidate fac...

Stable and clear visible facial features are crucial for the tasks in human face perception, such as face detection and tracking. Among other features, the center point between the eyes, or the “Between-the-Eyes” (BTE) has been found to be one of the good choices. In this paper, we propose a simple and fast way of extracting this facial feature from a facial image. By using down-sampling strate...

In the title compound, C11H9BrO, the cyclo-pentenone ring is almost planar with an r.m.s. deviation of 0.0097 Å. The largest inter-ring torsion angles [2.4 (3), 1.3 (3) and 3.53 (2)°] reveal only a very small twist between the rings, and suggest that the two rings are conjugated. The mol-ecule is slightly bowed, as shown by the small dihedral angle between the rings [5.3 (1)°]. The crystal pack...

abstract therapy-related symptom checklist for children (trsc-c) was developed as a symptom assessment tool in children receiving chemotherapy. the objective of the present study was to evaluate the validity and reliability of the persian version of trsc-c. this cross-sectional study was conducted in 2013-2014 in tehran, iran. trsc-c was translated using backward-forward approach. the content v...

The title compound, C(30)H(22)O, does not form face-to-face π-π inter-actions despite the presence of four phenyl rings within the compound. Instead weak C-H⋯π inter-actions occur between adjacent mol-ecules, with C⋯C contact distances in the range 3.633 (4)-3.974 (4) Å. The ketone O atom also takes part in a weak C-H⋯O inter-action. The three pendant phenyl rings are twisted relative to the ce...

Tubulin-binding cofactor C stimulates GTPase activity and contributes to the release of the heterodimeric α/β-tubulin from a super-complex of tubulin monomers and two ancillary cofactors. We have determined the 2.2 Å resolution crystal structure of the C-terminal domain of tubulin-binding cofactor C from Leishmania major based on single wavelength anomalous dispersion measurements targeting a s...
