A Stratal OT Approach to a Noun-Verb Asymmetry With Respect to Opacity in Korean

This paper revisits the well-known opacity caused by the interaction of post-obstruent tensification and coda cluster simplification in Korean and suggests a new class of data that threatens the validity of previous approaches. The new data shows that the opacity occurs only if the input belongs to a certain morphological category such as verb. Therefore, it calls for a theory in which morphology and phonology are systematically interleaved, such as Stratal OT (Kiparsky, 2000). I show that the Stratal OT approach provides a solution to the problem since it adds derivational effects as well as morphological insights to an OT grammar

Prosodic disambiguation of wh-indeterminates in Mandarin Chinese

This study focuses on naturally occurring ambiguous utterances like “Zhōngguóduì shuí yě dǎ-bù-guò” in Mandarin to study if/how prosody is used for disambiguation of wh-indeterminates. The results of our production study suggest that wh-indeterminates are disambiguated prosodically. For the wh-region, interrogative readings are distinguished from indefinite readings by having a longer duration and higher maximum pitch. For the pre-wh region, longer duration was observed when the wh-word received interrogative readings and left-dislocated. For the post-wh region, significantly greater pitch excursion was observed for indefinite reading than for interrogative reading. In particular, the novel finding of post-wh pitch compression for wh-interrogatives in Mandarin is in line with what has been attested in other wh-in-situ languages, such as Japanese and Korean, which suggests shared prosodic mechanisms for disambiguating wh-indeterminates in wh-in-situ languages

Vowels of Beryozovka Ewen: An Acoustic Phonetic Study

This study acoustically analyzes 13,540 vowel tokens of Beryozovka Ewen with the aid of automated post-transcriptional processing technique. The focus of the analysis is on the acoustic correlates of [RTR], which is the harmonic feature of the language. In addition to the first three formants, acoustic values representing spectral tilt such as H1−H2, H1−A2, and B1 are measured as potential acoustic cues of [RTR]. The results show that F1, F3, and B1 are the most reliable cues of the feature and that H1− H2 and H1−A2 are nearly reliable. These acoustic cues are also shown to interact with length and position. In general, the acoustic distance between [−RTR] and [+RTR] vowels are farther in long and word-initial vowels than in short and non-initial vowels, respectively. We claim that [RTR] is more appropriate for the harmonic feature of Ewen than [ATR], and that the greater perceptibility of word-initial vowels is understood as a means to facilitate the lexical access in a language with vowel harmony

Algorithmic decomposition for efficient multiple nuclear spin detection in diamond

Efficiently detecting and characterizing individual spins in solid-state hosts is an essential step to expand the fields of quantum sensing and quantum information processing. While selective detection and control of a few 13C nuclear spins in diamond have been demonstrated using the electron spin of nitrogen-vacancy (NV) centers, a reliable, efficient, and automatic characterization method is desired. Here, we develop an automated algorithmic method for decomposing spectral data to identify and characterize multiple nuclear spins in diamond. We demonstrate efficient nuclear spin identification and accurate reproduction of hyperfine interaction components for both virtual and experimental nuclear spectroscopy data. We conduct a systematic analysis of this methodology and discuss the range of hyperfine interaction components of each nuclear spin that the method can efficiently detect. The result demonstrates a systematic approach that automatically detects nuclear spins with the aid of computational methods, facilitating the future scalability of devices.Comment: 4 figures, 2 table

Design of Single-modal Take-over Request in SAE Level 2 & 3 Automated Vehicle

Recently, cutting-edge technology has led to the development of automated vehicles, but the limitations of the related technology may lead to hazardous situations. This resulted in the remarkable significance of the interaction between automated vehicles and drivers. In particular, the transition between the driver and the automated vehicle in accordance with Level 3 of SAE J3016 is inevitable, and guidelines or standards regarding the takeover should be provided. Therefore, we aim to prepare the safety guidelines for the takeover and to conduct a comparative test. First, guidelines for visual, auditory, and haptic displays in existing vehicles were examined. Second, preliminary research was conducted on the modality of automated vehicles. Third, we carried out a modality investigation regarding the partially automated vehicle. Based on this, we proposed visual, auditory, and haptic signals for each modality. This will serve as a significant starting point for future research based on multimodal methods
