ABSTRACT Objective: To describe, using a three-dimensional finite element (FE) model, the initial force system generated during bodily movement of upper canines with plastic aligners with and without composite attachments. Materials and Methods: A CAD model of an upper right canine, its alveolar bone and periodontal ligament, thermoformed plastic aligner, and two light-cured composite attachments were constructed. A FE model was used to analyze the effects of imposing a distal movement condition of 0.15 mm on the aligner (simulating the mechanics used to produce a distal bodily movement) with

Abstract:

AbstractWe introduce a class of non-uniform random recursive trees grown with an attachment preference for young age. Via the Chen–Stein method of Poisson approximation, we find that the outdegree of a node is characterized in the limit by ‘perturbed’ Poisson laws, and the perturbation diminishes as the node index increases. As the perturbation is attenuated, a pure Poisson limit ultimately emerges in later phases. Moreover, we derive asymptotics for the proportion of leaves and show that the limiting fraction is less than one half. Finally, we study the insertion depth in a random tree in thi

Attachment devices are essential adaptations for climbing animals and valuable models for synthetic adhesives. A major unresolved question for both natural and bioinspired attachment systems is how attachment performance depends on size. Here, we discuss how contact geometry and mode of detachment influence the scaling of attachment forces for claws and adhesive pads, and how allometric data on biological systems can yield insights into their mechanism of attachment. Larger animals are expected to attach less well to surfaces, due to their smaller surface-to-volume ratio, and because it become

Abstract:

One of the important problems appearing in experimental realizations of artificial adhesives inspired by gecko foot hair is so-called clusterization. If an artificially produced structure is flexible enough to allow efficient contact with natural rough surfaces, after a few attachment–detachment cycles, the fibres of the structure tend to adhere one to another and form clusters. Normally, such clusters are much larger than original fibres and, because they are less flexible, form much worse adhesive contacts especially with the rough surfaces. Main problem here is that the forces responsible f

The enhanced shear rate is attributed to the wavy flows that develop over the ribbed surface and the weak vortices that form between adjacent ribs.

Abstract Mandarin manner adverbs like dasheng ‘loudly’ (lit. ‘big voice’) occur both sentence-medially and sentence-finally, whereas adverbs formed with the adverbializer de (地) like kuaikuaide ‘quickly’ occur only sentence-medially. The behavior of AP-地 adverbs is puzzling under a classical adjunction analysis and under Cinque’s (1999) hierarchy of functional projections. Here, I argue that Mandarin manner adverbs have a uniform low attachment in V complement position and that preverbal/medial position reflects obligatory movement imposed by the status of 地 as a “concordializing element”.

Abstract:

We investigated the effect of the 52 MAR (matrix attachment region) sequence of chicken lysozyme gene as a possible insulator for the expression of our transgenes in somatic cells to be used for nuclear transfer. With the preliminary purpose to demonstrate a possible positive effect (position or copy number) on the long-term combined expression during in vitro culture, we have created a bicistronic ubiquitous expression vector with (MAR+) or without (MAR–) MAR. The main structure of our constructs is composed of the pCAGGS promoter driving the expression of a reporter gene (enhanced green fluo

Abstract:

Ultrananocrystalline diamond (UNCD) has been demonstrated to have attractive features for biomedical applications and can be combined with nanoporous membranes for applications in drug delivery systems, biosensing, immunoisolation and single molecule analysis. In this study, free-standing nanoporous UNCD membranes with pore sizes of 100 or 400 nm were fabricated by directly depositing ultrathin UNCD films on nanoporous silicon nitride membranes and then etching away silicon nitride using reactive ion etching. Successful deposition of UNCD on the substrate with a novel process was confirmed wit

Abstract:

This work concerns with improving the transmission loss offered by a noise barrier separating two acoustic spaces in the low-frequency range. A novel concept of local mitigation of the transmitted noise at a target receiver location is presented by controlling the directivity of the transmitted noise through a point mass attachment on the barrier surface. Mass attachment at an arbitrary location is shown to increase the noise transmission. Optimal locations of the mass to minimize the sound transmission in the normal, oblique and tangential directions to the barrier are obtained. Optimal place

Abstract:

Abstract A random graph evolution based on interactions of N vertices is studied. During the evolution both the preferential attachment rule and the uniform choice of vertices are allowed. The weight of an M-clique means the number of its interactions. The asymptotic behaviour of the weight of a fixed M-clique is studied. Asymptotic theorems for the weight and the degree of a fixed vertex are also presented. Moreover, the limits of the maximal weight and the maximal degree are described. The proofs are based on martingale methods.

Abstract:

AbstractIn this paper, we investigate the degree profile and Gini index of random caterpillar trees (RCTs). We consider RCTs which evolve in two different manners: uniform and nonuniform. The degrees of the vertices on the central path (i.e., the degree profile) of a uniform RCT follows a multinomial distribution. For nonuniform RCTs, we focus on those growing in the fashion of preferential attachment. We develop methods based on stochastic recurrences to compute the exact expectations and the dispersion matrix of the degree variables. A generalized Pólya urn model is exploited to determine th

Abstract:

Leafy vegetables exhibit non-uniform surfaces and are structured with interconnected networks of veinlets or wrinkle characteristics, making the quantification of the changes rather difficult. In this study, attempt was made to quantify the surface topographical features of leafy vegetable. Image analysis was used to determine the characteristic of vegetable surface. In term of surface area (A), the results were compared with those correlated with the data obtained by a conventional measurement method. It was also performed to determine fractal dimension (FD) and roughness value (R) to describ

Abstract:

Uniformity is a key parameter to assure the accuracy of biosensor devices. In this work, highly uniform carbon nanotube thin-film transistors (CNT-TFTs) with a standard deviation of threshold voltage ([Formula: see text]) as small as 0.04 were achieved by accurately controlling the fabrication process, which is so far the most stable distribution to our knowledge. On-state current ([Formula: see text]), off-state current and on/off current ratio also exhibit high uniformity with low standard deviation of 0.50, 0.72 and 0.54, respectively. Given the high uniformity, high stability and high sens

Abstract:

AbstractA new network evolution model is introduced in this paper. The model is based on cooperations of N units. The units are the nodes of the network and the cooperations are indicated by directed links. At each evolution step N units cooperate, which formally means that they form a directed N-star subgraph. At each step either a new unit joins the network and it cooperates with N − 1 old units, or N old units cooperate. During the evolution both preferential attachment and uniform choice are applied. Asymptotic power law distributions are obtained both for in-degrees and for out-degrees.

Abstract:

Copper pillars in FCCSP positioned on the substrate are being used instead of solder only joints to meet reliability targets and the demand for smaller feature size, thinner dies and to achieve a well defined stand off. The transfer of the copper pillars from the die to the substrate is required to ensure a reliable thinning process for the dies. The plated copper pillar geometry is dependent on the size of the solder resist opening and thickness. The uniformity and in particular the height of the pillar is very dependant on the electrolytic copper plating parameters used. The height uniformit
