■ Contrasts between implicit and explicit knowledge in the serial reaction time (SRT) paradigm have been challenged because they have depended on a single dissociation: intact implicit knowledge in the absence of corresponding explicit knowledge. In the SRT task, subjects respond with a corresponding keypress to a cue that appears in one of four locations. The cue follows a repeating sequence o...

In the mol-ecule of the title compound, C(15)H(11)NS, the butterfly angle between the two planes defined by the two wings of the phenothia-zine unit is 33.5 (8)°. The dihedral angles between the two benzene rings and the propynyl group are 85 (4) and 63 (4)°.

■ Neurological patients with focal lesions in the dorsolateral prefrontal cortex and age-matched control subjects were tested on an auditory version of the delayed-match-to-sample task employing environmental sounds. Subjects had to indicate whether a cue (S1) and a subsequent target sound (S2) were identical. On some trials, S1 and S2 were separated by a silent period of 5 sec. On other trials...

This paper describes our approaches and results in NTCIR10 INTENT-2 task. In this year, we participate in subtasks for both the Chinese and English topics. We extract subtopics from multiple resources for these topics, and several subtopic clustering and re-ranking methods are proposed in this work. In Document Ranking subtask, we redefine the novelty of a document and use the new definition to...

We present the results of a 2-10 keV BeppoSAX survey based on 140 high galactic latitude MECS fields, 12 of which are deep exposures of “blank” parts of the sky. The limiting sensitivity is 5 × 10 erg cmswhere about 25% of the Cosmic X-ray Background (CXB) is resolved into discrete sources. The logNlogS function, built with a statistically complete sample of 177 sources, is steep and in good ag...

The crystal structure of the title compound, C(21)H(15)N(2)O(4) (+)·CF(3)O(3)S(-), is stabilized by C-H⋯O and C-H⋯F hydrogen bonds, by C-F⋯π, N-O⋯π and S-O⋯π inter-actions, and by O⋯O [2.70 (4) Å] and O⋯F [2.85 (1) or 2.92 (1) Å] contacts; π-π interactions are also present. In the packing of the mol-ecules, acridine units are either parallel or inclined at an angle of 12.5 (1)°. The nitrophenox...

The title compound, C(13)H(10)N(+)·C(7)H(4)NO(4) (-), consists of a protonated acridinium cation and a 6-carb-oxy-pyridine-2-carboxyl-ate monoanion. The carboxyl-ate group of the anion appears to be delocalized on the basis of the nearly equivalent C-O bond lengths. In the crystal, the anions are connected by strong O-H⋯O hydrogen bonds, forming chains along the b axis. The acridinium cations a...

In the crystal structure of the title compound, C(21)H(15)BrNO(2) (+)·CF(3)SO(3) (-), adjacent cations are linked through C-Br⋯π and π-π contacts [centroid-centroid distance = 3.744 (2) Å], and neighbouring cations and anions via C-H⋯O, C-F⋯π and S-O⋯π inter-actions. The acridine and benzene ring systems are oriented at a dihedral angle of 18.7 (1)°. The carb-oxy group is twisted at an angle of...
