According to Huang (1987), all Chinese existential sentences involve the string of “... (NP) ... V ... NP ... (XP) ...”. When the V position is occupied by the verb you, the XP is refered to as you-coda. It has been observed that although the aspect markers zhe and le may alternate in the locative inversion construction (LIC), the superficially identical V-le and V-zhe sequences cannot appear i...
This acoustical and Electroglottography (EGG) study investigates the effect of coda deletion and co-articulatory phasing on vowels and final coda stops, [p t k ʔ], in Taiwan Min checked tones 3 and 5 syllables. Vowel duration, f0, spectral tilt (H1*-A3*), cepstral peak prominence (CPP) and glottal contact quotient (CQ_H) were analyzed. Compensatory lengthening, f0 lowering and increasing period...
When speakers of Puerto Rican Spanish (PRS) produce phonemic coda taps, Spanish-speakers of other dialects often perceive these as laterals. We observed production of phonemic coda laterals and taps by a male PRS speaker in real-time MRI. Temporal and spatial characteristics of tongue tip movements during coda liquid production are inconsistent with accounts positing a categorical change from r...
We first describe how the Coda distributed filesystem was ported to Windows 95 and 98. Coda consists of user level cache managers and servers and kernel level code for filesystem support. Severe reentrancy difficulties in the Win32 environment on this platform were overcome by extending the DJGPP DOS C compiler package with kernel level support for sockets and more flexible memory management. W...
This study examines the coda voicing effect in English on production of preceding vowel by comparing L1 and L2 speech. Particular attention is paid to how coda voicing contrast is encoded in temporal vs. spectral dimensions, how the effect interacts with information structure (with varying focus types), and how the use of information structure differs in L1 vs. L2. Both English (native) and Kor...
[1] The coda of seismic waves consists of that part of the signal after the directly arriving phases. In a finite medium, or in one that is strongly heterogeneous, the coda is dominated by waves which have repeatedly sampled the medium. Small changes in a medium which may have no detectable influence on the first arrivals are amplified by this repeated sampling and may thus be detectable in the...
در این تحقیق به منظور دستیابی به برنج تراریخته حاوی ژن کولین اکسیداز و فاقد ژن نشانگر انتخابی، پلاسمیدهای بیانی حاوی ژن "کولین اکسیداز" pabrii-chl (حاوی پپتید راهنما برای تظاهر در کلروپلاست) و pabrii-cyt (بدون پپتید راهنما برای تظاهر در سیتوپلاست) ساخته شد و سپس با استفاده از روش تراریزش توأم، به همراه پلاسمید ptra132 حامل ژن مقاومت به هیگرومایسین (hph)، به کالوس های جنین زایی که از ناحیه اسکوت...
This project investigates the relationship of vowel duration and coda duration in modern Welsh monosyllabic words ending in a simplex consonant. Acoustic data from 16 native speakers from the two major dialectal varieties of Welsh were analysed. We found vowel duration highly predictive by coda duration, taking into account possible influences of phrase prosody, speaker and variety specific dev...
-The early P wave coda (5-15 sec after the first arrival) of underground explosions at the Nevada Test Site is studied in the time domain using 2082 teleseismic short-period recordings, with the intent of identifying near-source contributions to the signals in the frequency range 0.2-2.0 Hz. Smaller magnitude events tend to have relatively high coda levels in the 0.4-0.8 Hz frequency band for b...
