Abstract
Studies on perception and cognition require sound methods allowing us to disentangle the basic sensory processing of physical stimulus properties from the cognitive processing of stimulus meaning. Similar to the scrambling of images, the scrambling of auditory signals is aimed at creating stimulus instances that are unrecognizable but have comparable low-level features. In the present study, we generated scrambled stimuli of short vocalizations taken from the Montreal Affective Voices database (Belin et al., Behav Res Methods, 40(2):531-539, 2008) by applying four different scrambling methods (frequency-, phase-, and two time-scrambling transformations). The original stimuli and their scrambled versions were judged by 60 participants for the apparency of a human voice, gender, and valence of the expressions, or, if no human voice was detected, for the valence of the subjective response to the stimulus. The human-likeness ratings were reduced for all scrambled versions relative to the original stimuli, albeit to a lesser extent for phase-scrambled versions of neutral bursts. For phase-scrambled neutral bursts, valence ratings were equivalent to those of the original neutral burst. All other scrambled versions were rated as slightly unpleasant, indicating that they should be used with caution due to their potential aversiveness.

Abstract
The present study investigated the canonical position of instrumental and locative adverbial phrases in both Japanese sentences and noun phrases to determine whether the canonical positions are parallel. A series of sentence/phrase decision tasks were used to compare sentences with different word-orders, including sentences with SAdvOV (S is subject phrase, Adv adverb, O object phrase and V verb), AdvSOV, SAdvOV and SOAdvV word orders. SAdvOV word order was found to be the most quickly processed, for both instrumental adverbial (Experiment 1) and locative adverbial phrases (Experiment 2). Thus, the canonical position for these adverbial phrases is identified as the position immediately preceding the object (Theme argument). This finding was replicated when the same experimental methods were applied to event-denoting noun phrases. Adverbial adjuncts in the initial position (AdvON, N is noun phrase) were processed more quickly and accurately than noun phrases with adverbial phrases in the second position (OAdvN), for both instrumental adverbial (Experiment 3) and locative adverbial phrases (Experiment 4). Therefore, the position immediately preceding the object is the canonical position for both instrumental and locative adverbial phrases in sentences and in noun phrases. In conclusion, this indicates that the base structure of a sentence is shared by its related noun phrase.

Abstract
Odd-nosed monkeys 'arm-swing' more frequently than other colobines. They are therefore somewhat behaviorally analogous to atelines and apes. Scapular morphology regularly reflects locomotor mode, with both arm-swinging and climbing anthropoids showing similar characteristics, especially a mediolaterally narrow blade and cranially angled spine and glenoid. However, these traits are not expressed uniformly among anthropoids. Therefore, behavioral convergences in the odd-nosed taxa of Nasalis, Pygathrix, and Rhinopithecus with hominoids may not have resulted in similar structural convergences. We therefore used a broad sample of anthropoids to test how closely odd-nosed monkey scapulae resemble those of other arm-swinging primates. We used principal component analyses on size-corrected linear metrics and angles that reflect scapular size and shape in a broad sample of anthropoids. As in previous studies, our first component separated terrestrial and above-branch quadrupeds from clambering and arm-swinging taxa. On this axis, odd-nosed monkeys were closer than other colobines to modern apes and Ateles. All three odd-nosed genera retain glenoid orientations that are more typical of other colobines, but Pygathrix and Rhinopithecus are closer to hominoids than to other Asian colobines in mediolateral blade breadth, spine angle, and glenoid position. This suggests that scapular morphology of Pygathrix may reflect a significant reliance on arm-swinging and that the morphology of Rhinopithecus may reflect more reliance on general climbing. As 'arm-swinging' features are also found in taxa that only rarely arm-swing, we hypothesize that these features are also adaptive for scrambling and bridging in larger bodied anthropoids that use the fine-branch component of their arboreal niches.

Abstract
Phospholipid scramblases catalyze the rapid trans-bilayer movement of lipids down their concentration gradients. This process is essential for numerous cellular signaling functions including cell fusion, blood coagulation, and apoptosis. The importance of scramblases is highlighted by the number of human diseases caused by mutations in these proteins. Because of their indispensable function, it is essential to understand and characterize the molecular function of phospholipid scramblases. Powerful tools to measure lipid transport in cells are available. However, these approaches provide limited mechanistic insights into the molecular bases of scrambling. Here we describe in detail an in vitro phospholipid scramblase assay and the accompanying analysis which allows for determination of the macroscopic rate constants associated with phospholipid scrambling. Notably, members of the TMEM16 family of scramblases also function as nonselective ion channels. To better understand the physiological relevance of this channel function as well as its relationship to the scrambling activity of the TMEM16s we also describe in detail an in vitro flux assay to measure nonselective channel activity. Together, these two assays can be used to investigate the dual activities of the TMEM16 scramblases/nonselective channels.

Abstract
Using functional magnetic resonance imaging (fMRI), we show that the neural substrate of language does not overlap with that for verbal working memory when we carefully define verbal working memory in sentence processing. Object-Subject-Verb (OSV) sentences in Japanese were contrasted with canonical Subject-Object-Verb (SOV) sentences, which had less hierarchy in linguistic structure. This contrast revealed the posterior part of Broca's area and the left posterior middle temporal gyrus (pMTG) as the neural bases for hierarchical structure building. Furthermore, we changed verbal working memory load in OSV sentences by adding modifiers to the subject or object noun phrases; this resulted in the activation in the op9, which is situated in the frontal operculum and is adjacent to, but not situated in, Broca's area. The neuroanatomical segregation of language processing from verbal working memory suggests independence of the faculty of language from the verbal working memory system, providing evidence for the domain-specificity of language in human cognition.

Abstract
The lipid distribution of plasma membranes of eukaryotic cells is asymmetric and phospholipid scramblases disrupt this asymmetry by mediating the rapid, nonselective transport of lipids down their concentration gradients. As a result, phosphatidylserine is exposed to the outer leaflet of membrane, an important step in extracellular signaling networks controlling processes such as apoptosis, blood coagulation, membrane fusion and repair. Several TMEM16 family members have been identified as Ca2+-activated scramblases, but the mechanisms underlying their Ca2+-dependent gating and their effects on the surrounding lipid bilayer remain poorly understood. Here, we describe three high-resolution cryo-electron microscopy structures of a fungal scramblase from Aspergillus fumigatus, afTMEM16, reconstituted in lipid nanodiscs. These structures reveal that Ca2+-dependent activation of the scramblase entails global rearrangement of the transmembrane and cytosolic domains. These structures, together with functional experiments, suggest that activation of the protein thins the membrane near the transport pathway to facilitate rapid transbilayer lipid movement.

Abstract
Chromosome synthesis is still at its early stage. The budding yeast Saccharomyces cerevisiae is an organism of choice with respect to this field, thanks to its efficient homologous recombination pathway. By iteratively concatenating short DNA molecules to ultimately generate large sequences of megabase size, these approaches allow piecing together multiple genes and genetic elements in a way designed by an individual prior to their assembly. They therefore hold important promises as a tool to design complex genetic systems or assemble new genetic pathways that allow addressing fundamental and applied questions. The constant drop in DNA synthesis costs, fed by the development of new technologies, opens new perspectives with respect to the conceptual way these questions can be addressed. Thanks to its properties, S. cerevisiae may provide solutions for chromosome synthesis in other organisms, in combination with genome editing techniques.

Abstract
This study investigates preverbal structural and semantic processing in Japanese, a head-final language, using the maze task. Two sentence types were tested-simple scrambled sentences (Experiment 1) and control sentences (Experiment 2). Experiment 1 showed that even for simple, mono-clausal Japanese sentences, (1) there are online processing costs associated with parsing noncanonical word orders and (2) these costs are incurred during the incremental integration of constituents into developing sentence representations. Experiment 2 indicated (1) that antecedents are provisionally assigned to empty subjects in Japanese control sentences before verb information becomes available and (2) that this process is guided by an object control bias. Taken together, these findings are interpreted to suggest an important role for preverbal analysis in the processing of displaced constituents and of referential properties for empty elements in head-final languages.

Abstract
Although it is widely accepted that colors facilitate object and scene recognition under various circumstances, several studies found no effects of color removal in tasks requiring categorization of briefly presented animals in natural scenes. In this study, three experiments were performed to test the assumption that the discrepancy between empirical data is related to variations of the available meaningful global information such as object shapes and contextual cues. Sixty-one individuals categorized chromatic and achromatic versions of intact and scrambled images containing either cars or birds. While color removal did not affect the classification of intact stimuli, the recognition of moderately scrambled achromatic images was more difficult. This effect was accompanied by amplitude modulations of occipital event-related potentials emerging from approximately 150ms post-stimulus. Our results indicate that colors facilitate stimulus classification, but this effect becomes prominent only in cases when holistic processing is not sufficient for stimulus recognition.
