In [19] we specified robot grippers that can orient and grasp parts with an arrangement of trapezoidal jaw modules. Since jaw modules may be imprecisely machined, we define a parametric tolerance class such that part alignment is guaranteed for all jaw geometry in the class. This tolerance class is derived based on analysis of toppling, motion trajectory, and form-closure. Given maximal jaw geo...

A protrusible upper jaw has independently evolved multiple times within teleosts and has been implicated in the success of two groups in particular: Acanthomorpha and Cypriniformes. We use digital particle image velocimetry (DPIV) to compare suction feeding flow dynamics in a representative of each of these clades: goldfish and bluegill. Using DPIV, we contrast the spatial pattern of flow, the ...

INTRODUCTION The mandible and maxilla can be the site of myriads of lesions that may be categorized as neoplastic, cystic, reactive and infective or inflammatory. Literature reviewing jaw swellings in an amalgamated fashion are uncommon, probably because aetiologies for these swellings are varied. However, to appreciate their relative relationship, it is essential to evaluate the clinico-pathol...

The interaction of organismal design with ecology, and its evolutionary development are the subject of many functional and ecomorphological studies. Many studies have shown that the morphology and mechanics of the masticatory apparatus in mammals are adapted to diet. To investigate the relations between diet and the morphological and physiological properties of the lizard jaw system, a detailed...

The jaws of the marine worm Nereis sp. are made of protein fibers and are reinforced by zinc. Here we study a transverse section through the jaw using optical microscopy and nanoindentation. Optical microscopy images demonstrate a complex microstructure which includes channels that extend throughout the jaw. We suggest that these channels may be related to jaw remodeling. The mechanical results...

This study examines some intonational and rhythmical aspects of speech and their interactions. The intonational analysis framework is the ToBi system; the rhythmical analysis framework is based on patterns of jaw opening acoustically reflected by F2-F1 changes. According to recent studies on American English, contrastively emphasized mono-syllabic words, regardless of vowel height, have larger ...

Colorectal masses can be non-neoplasm, benign neoplasm and malignant neoplasm. Diagnosis of colorectal mass done by biopsy or surgery then followed histopathological examination. The aim this study was to described the histopathology feature in Anatomic Pathology Laboratory Arifin Achmad Regional Hospital Riau Province January 2015 - December 2019. This found 304 cases consisted men (55,6%) wom...

The pharyngeal jaw of cichlids may represent a key innovation that facilitated their unparalleled trophic divergence. In cichlids, 'fusion' of the lower pharyngeal jaw (LPJ) results from suturing between the two lower ceratobranchials. To examine, what novel abilities a more extensively fused pharyngeal jaw may confer, the function of LPJ suturing was examined in Heroine cichlids. Greater LPJ s...

The aim of this study was to investigate the potential of jaw tracking with the volumetric-modulated arc therapy (VMAT) to reduce the normal tissue dose. Plans of nasopharynx, lung, and prostate cancers (10 plans for each) were used to perform VMAT with and without jaw tracking. The dose reduction was evaluated in terms of organ doses and integral doses. Organ-dose reduction with jaw tracking w...
