The influence of city traffic-induced vibration on Vilnius Arch-Cathedral Belfry is investigated. Two sources of dynamic excitation are studied. Conventional city traffic is considered to be a natural...
The aim of this retrospective study was to evaluate and compare the anchorage provided with the Nance appliance (NA) and the fixed frontal bite plane (FBP) during intra-arch distal molar movement....
The objectives of this study were to determine the mean mesiodistal tooth width of the dentition, Bolton anterior and overall ratios, arch length, and arch width in the different malocclusions in a ...
The objective of this study was to compare the dental arch dimensions in the mixed dentition in two modern samples living in the same geographic area and separated by almost 35 years. A group of 83 ...
The objective was to analyze variations in dental arch width in relation to oral habits. Maxillary and mandibular intercanine and intermolar distance were determined in relation to certain oral habi...
The aim of this study was to provide an anatomical map to assist the clinician in miniscrew placement in a safe location between dental roots. Volumetric tomographic images of 25 maxillae and 25 man...
Objective: To evaluate the transverse stability of the dental arch in unilateral cleft lip and palate (UCLP) patients after orthodontic treatment with quadhelix and edgewise appliances.Materials and M...
Objective: To compare (1) arch widths in adults with Class II division 2 (II-2), Class II division 1 (II-1), and Class I normal occlusions, (2) genders, (3) gender dimorphism, (4) differences between ...
Objective: To test the hypothesis that there is no difference between adults with Class I crowded (CICR), Class III (CIII), and Class I normal (CIN) occlusions with respect to (1) arch widths, (2) wid...
Objective: To investigate the patterns of dental crowding in the lower arch and their contributing morphological and functional factors.Materials and Methods: Pretreatment diagnostic materials from 16...
Objective: To analyze the development of the dental arches and skeletal mandibular-maxillary bases in untreated Class III malocclusions with low averages and high mandibular plane angles in subjects a...
Objective: To present a comprehensive mathematical analysis of dental arch curvature in subjects with normal occlusion.Materials and Methods: The materials studied were 40 sets of upper and lower plas...

通过引入波动性状态转移的ARCH(SWARCH) 模型对中国股票市场的波动性进行了研究。SWARCH模型较传统的ARCH类模型显著地提高了股票市场波动性的描述与预测能力。实证结果表明,促使中国股市低波动性状态向高波动性状态转移的主要原因是股市的政策因素,这与因为实体经济基础的变化而促使美国股市波动性状态转移有着本质的区别。
A rare case is presented in which a congenitally missing primary canine, an abnormally formed primary first molar and an impacted supernumerary premolar were found in the same lower left quadrant. The...
