Article Abstract
Objective: the present study aimed to investigate the applicability and feasibility of a new paradigm for assessing sound lateralization behavior.
Design: The Click Ordering Lateralization Test comprises two tracks (tracks 1 and 2), with 54 trials each. Each trial consists of one of nine intervals ranging from 0 to 230 ms between two noise bursts, whereby subjects must indicate on which side they first heard the noise. The COLT procedure was applied to 30 normal-hearing children (between 8 and 14 years old).
Results: the results indicated that an interaural time difference (ITD) of 0 ms functions as a control item, and after an ITD of 170 ms, the lateralization threshold reaches a ceiling effect. Different analysis methods were investigated in this study, with the total percentage score and a lateralization threshold of 5 hits deemed the most reliable methods. No differences were observed between test tracks and performance across the tracks was shown to be reliable and equivalent.
Conclusions: there are few procedures available to assess sound laterization in a clinical setting. This study presents the COLT as an easy-to-apply, reliable test for use in children aged between 8 and 14 years old.

ConspectusThe design of properties and functions of molecular assemblies requires not only a proper choice of building blocks but also control over their packing arrangements. A highly versatile unit in this context is a particular type of triptycene with substituents at the 1,8,13-positions, called tripodal triptycene, which offers predictable molecular packing and multiple functionalization sites, both at the opposite 4,5,16- or 10 (bridgehead)-positions. These triptycene building blocks are capable of two-dimensional (2D) nested hexagonal packing, leading to the formation of 2D sheets, which undergo one-dimensional (1D) stacking into well-defined "2D+1D" structures.

Well-defined amorphous/semi-crystalline statistical copolymers of n-dodecyl isocyanate, DDIC, and allyl isocyanate, ALIC, were synthesized via coordination polymerization using the chiral half-titanocene complex CpTiCl(O-(S)-2-Bu) as an initiator. In the frame of the terminal model, the monomer reactivity ratios of the statistical copolymers were calculated using both well-known linear graphical methods and the computer program COPOINT. The molecular and structural characteristics of the copolymers were also calculated.

Introduction: Implicit statistical learning is, by definition, learning that occurs without conscious awareness. However, measures that putatively assess implicit statistical learning often require explicit reflection, for example, deciding if a sequence is 'grammatical' or 'ungrammatical'. By contrast, 'processing-based' tasks can measure learning without requiring conscious reflection, by measuring processes that are facilitated by implicit statistical learning.

Recently, the use of click chemistry for localization of chemically modified cyanopeptides has been introduced, i.e., taking advantage of promiscuous adenylation (A) domains in non-ribosomal peptide synthesis (NRPS), allowing for the incorporation of clickable non-natural amino acids (non-AAs) into their peptide products.
