Earlier analyses of rime change (Lin 1989, 1993) posit subsegmental affixes such as featural or prosodic affixes (e.g. [+back, +round] or a mora/default vowel) and templatic output restrictions (e.g. an open syllable). In some cases of rime change, however, there are puzzling unexpected alternations or exceptions that are difficult to explain and analyze. This study examines Hong’an diminutive ...

mp2 calculations with cc-pvtz basis set were used to analyze intermolecular interactions in f3cx···yli···nccn and f3cx···nccn···liy triads (x = cl, br; y = cn, nc) which are connected via halogen and lithium bonds. those complexes with the role of liy as halogen acceptor and lithium donor show cooperativity with energy values ranging between -1.97 and -2.92 kj mol-1. those complexes with simult...

The possibility to predict in vivo the histology of colorectal polyps by advanced endoscopic imaging has resulted in the implementation of a more conservative management for diminutive lesions detected at colonoscopy. In detail, a predict-and-do-not-resect strategy has been proposed for diminutive lesions located in the rectosigmoid tract, whilst a predict-resect-and-discard policy has been adv...

The primary goal of colorectal cancer screening and prevention is the detection and removal of advanced neoplasia. Computerized tomography (CT) colonography is now well established as an effective screening test. Areas of greater uncertainty include the performance characteristics of CT colonography for detecting small (6-9 mm), diminutive (< or =5 mm), and flat (nonpolypoid) lesions. However, ...

Colorectal polyps are classified as neoplastic or non-neoplastic on the basis of malignant potential. All neoplastic polyps should be completely removed because both the incidence of colorectal cancer and the mortality of colorectal cancer patients have been found to be strongly correlated with incomplete polypectomy. The majority of colorectal polyps discovered on diagnostic colonoscopy are di...

Living vertebrates vary drastically in body size, yet few taxa reach the extremely minute size of some frogs and teleost fish. Here we describe two new species of diminutive terrestrial frogs from the megadiverse hotspot island of New Guinea, one of which represents the smallest known vertebrate species, attaining an average body size of only 7.7 mm. Both new species are members of the recently...

BACKGROUND Distal diminutive colorectal polyps are common and accurate endoscopic prediction of hyperplastic or adenomatous polyp histology could reduce procedural time, costs and potential risks associated with the resection. Within this study we assessed whether digital chromoendoscopy can accurately predict the histology of distal diminutive colorectal polyps according to the ASGE PIVI state...

Anchoring constraints were originally proposed for explaining the special faithfulness to edges, both in the domain of Input-Output correspondence (e.g. Benua 1998) and Base-Reduplicant correspondence (e.g. Hendricks 1998). In Optimality Theory framework (Prince & Smolensky 1993), this paper proposes two sets of anchoring constraints, Existential and Universal ANCHORING for edges and head, requ...
