Effects of Level of Retrieval Success on Recall-Related Frontal and Medial Temporal Lobe Activations
Behavioural Neurology, 2002 Brain dedicated single photon emission computed tomography (SPECT) was used to compare the neuroactivation produced by the cued recall of response words in a set of studied word pairs with that produced by the cued retrieval of words semantically related

Beam Combining of a Tunable Tilted Quantum Cascade Laser Array
Advanced Photonics Research, EarlyView.The four‐channel tilted waveguide with varying angles in the quantum cascade laser array, achieving a free tuning range of 100 nm and common‐aperture output simultaneously, is reported. The fabrication eliminates the necessity of electron‐beam lithography and is very promising for mass production in gas sensing industry.

Anisotropic Second‐ and Third‐Harmonic Hermite–Gaussian Beam Generation with NbOI2 Holograms
Advanced Photonics Research, EarlyView.Anisotropic second‐ and third‐harmonic Hermite–Gaussian (HG) beam generation is demonstrated with ultrathin NbOI2 grating holograms to produce the nonlinear HG01 and HG10 modes with high anisotropy ratios. The relative magnitudes of the second‐ and third‐order nonlinear susceptibility tensor elements of NbOI2 crystal are extracted. These demonstrations

Synthesis of Self‐Healing Microbeam by Superposition of Self‐Decelerating Corner‐Diffraction Beams
Advanced Photonics Research, EarlyView.Quasi‐nondiffracting (QND) beams boast long‐range propagation and self‐healing capabilities but require complex beam‐forming platforms. In contrast, the photonic nanojets (PNJs) boast simple platforms but are utilized primarily for near‐field applications. This work aims to hybridize the QND and PNJ beam concepts with a view to realize microscale, self‐

Advanced Science, EarlyView.Researchers discovered that fibronectin fibers lose their tension in specific areas of glioblastoma brain tumors, accumulating in the lumen of proliferating blood vessels and in parenchyma next to infiltrating immune cell clusters. A novel molecular tension probe enables the mapping of fibronectin's fiber tension in glioblastoma for the first time ...

The frontal lobe and aggression [PDF]
European Journal of Developmental Psychology, 2009 Frontal lesions often lead to psychosocial problems. It is not surprising that frontal lobe dysfunctions have been proposed to underlie antisocial behaviour in individuals without apparent lesions. However, physical aggression and violence have never been systematically related to acquired lesions.
