The claim by Furnes et al. (Reports, 23 March 2007, p. 1704) that Greenland metavolcanic rocks require Paleoarchean sea-floor spreading is incompatible with their own data. The purported sheeted dikes have the composition of pyroxenitic komatiite and could not have fed the adjacent ferroandesitic pillow lavas. Neither type has ophiolitic analogs, and both are likely ensialic.

Various bedding materials used in infancy, including duvets (or continental quilts), were tested for airflow using the British Standards Institution tests for pillows or fabrics. Resistance was also measured when the items were placed on a dummy infant face. Measurements were made on washed and unwashed garments, which were tested both dry and wet. Results suggest that all the bedding materials...

www.thoracic.org C LI P A N D C O P Y Sometimes nasal pillows that fit into a person’s nostrils are used instead of a mask. PAP therapy is a very effective way to treat OSA, but people sometimes can have problems with the machine and/or mask/nasal pillows. It is important to promptly address any problems that prevent you from using PAP therapy. The purpose of this fact sheet is to offer tips to...

The role of correlated firing in representing information has been a subject of much discussion. Several studies in retina, visual cortex, somatosensory cortex, and motor cortex, have suggested that it plays only a minor role, carrying <10% of the total information carried by the neurons (Gawne & Richmond, 1993; Nirenberg et al., 2001; Oram et al., 2001; Petersen, Panzeri, & Diamond, 2001; Roll...

In order to properly compare identification results between our methodology and the GLM framework, we used the same filter kernels and fixed the input signals used in identification. We also fixed the basis functions with respect to which both methods reconstruct the kernels. The latter was needed since the GLM typically employs basis functions that favor very particular kernels: those that osc...

PURPOSE Plaster casts can cause burns. Synthetic casts do not. Composite plaster-synthetic casts have not been thoroughly evaluated. This study analyzed the temperature from plaster casts compared with composite casts in a variety of in vitro conditions that would simulate clinical practice. METHODS A Pyrex cylinder filled with constant body temperature circulating water simulated a human ext...

When encountering familiar scenes, observers can use item-specific memory to facilitate the guidance of attention to objects appearing in known locations or configurations. Here, we investigated how memory for relational contingencies that emerge across different scenes can be exploited to guide attention. Participants searched for letter targets embedded in pictures of bedrooms. In a between-s...
