    Abstract Introduction: The aim of the study is to assess and correlate the different cephalometric parameters used to determine the vertical jaw relationship.
    Methods: Cephalometric radiographs from 148 patients were assessed and comparison was made using all eight parameters. Statistical analysis was performed using mean, standard deviation and coefficient of variance. A correlation was found between different variables using the Pearson's correlation coefficient.
    Results: In the entire sample, the basal plane angle displayed the most variable distribution, while the R angle displayed the most homogeneous distribution. There was a significant correlation found between the Jarabak ratio, Steiner's mandibular plane angle (SN-GoGn), Frankfort mandibular plane angle (FMA), R angle, and DR angle. There was a moderate to weak correlation between the Y-axis, basal plane angle, and facial height ratio with other skeletal analyses.
    Conclusion: Among angular variables DR angle, R angle, SN-GoGn and FMA can be used and among linear variables Jarabak ratio could be used reliably to assess the growth pattern. It suggested that in order to obtain an accurate evaluation of the vertical jaw relationship, a variety of measurements should be combined.

    Abstract We develop a framework to understand the mechanics of metamaterial sheets on curved surfaces. Here we have constructed a continuum elastic theory of mechanical metamaterials by introducing an auxiliary, scalar gauge-like field that absorbs the strain along the soft mode and projects out the stiff ones. We propose a general form of the elastic energy of a mechanism based metamaterial sheet and specialize to the cases of dilational metamaterials and shear metamaterials conforming to positively and negatively curved substrates in the Föppl-Von Kármán limit of small strains. We perform numerical simulations of these systems and obtain good agreement with our analytical predictions. This work provides a framework that can be easily extended to explore non-linear soft modes in metamaterial elasticity in future.

    Abstract The valence bond (VB) theory uses localized orbitals, and its wave function is composed of a linear combination of various VB structures which are based on sets of spin functions. The VB structures are not unique, and different sets are used, Rumer sets being the most common for classical VB due to their advantage as being both easily obtained as linearly independent and meaningful. Yet, Rumer rules, which are responsible for the simplified process of obtaining the Rumer sets, are very restrictive. Furthermore, Rumer sets are best suited for cyclic systems; however, in noncyclic systems, structures resulting from Rumer rules are often not the most intuitive/suitable structures for these systems. We have developed a method to obtain chemically insightful structures, which is based on concepts of chemical bonding. The method provides sets of VB structures with improved chemical insight, which can also be controlled. Parallel to the Rumer structures, the chemical insight sets of structures are based on electron pair coupling, and hence, pictorially can be drawn similarly to the Lewis structures. Yet, different from Rumer rules, the chemical insight method, being more flexible, allows larger combinations of bonds as well as larger combinations of structures in the sets it offers, resulting in many more possible sets that are better adapted to the systems studied.

    Abstract Significant attention has been drawn in recent years to develop porous scaffolds for tissue engineering. In general, porous scaffolds are used for non-load bearing applications. However, various metallic scaffolds have been investigated extensively for hard tissue repair due to their favorable mechanical and biological properties. Stainless steel (316L) and titanium (Ti) alloys are the most commonly used material for metallic scaffolds. Although stainless steel and Ti alloys are employed as scaffold materials, it might result in complications such as stress shielding, local irritation, interference with radiography, etc. related to the permanent implants. To address the above-mentioned complications, degradable metallic scaffolds have emerged as a next generation material. Among the all metallic degradable scaffold materials, magnesium (Mg) based material has gained significant attention owing to its advantageous mechanical properties and excellent biocompatibility in a physiological environment. Therefore, Mg based materials can be projected as load bearing degradable scaffolds, which can provide structural support toward the defected hard tissue during the healing period. Moreover, advanced manufacturing techniques such as solvent cast 3D printing, negative salt pattern molding, laser perforation, and surface modifications can make Mg based scaffolds promising for hard tissue repair. In this article, we focus on the advanced fabrication techniques which can tune the porosity of the degradable Mg based scaffold favorably and improve its biocompatibility.
