Study of selected specimens of Gymnomitrion collected by D. G. Long in Yunnan, China, revealed a new species, G. fissum Mamontov et Potemkin, sp. nov., with a fissured leaf surface. Comparison of SEM images of the leaf surface and leaf cross sections shows that the leaf surface of G. fissum is different from that of other known species with a superficially similar leaf surface, i. e. Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula. It has fissures around the cell lumen rather than grids and perforations. Outer cell walls of Gymnomitrion fissum are much thicker than in Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula, and their outer layers tend to be partly or completely caducous. G. fissum is related to the group of species assigned to the former genus Apomarsupella.

The western and eastern branches of Christianity, broadly speaking Roman Catholicism (RC) and Eastern Orthodoxy (EO), have been formally separate for almost a millennium. Yet they share the fundamental dogmas laid down by the first ecumenical councils. History and politics are entwined in the disputes since the Great Schism of 1054, but even earlier there was controversy over basic dogmatic questions and other doctrinal matters. Some, like using leavened or unleavened bread for Consecration, are now considered “matters of custom,” not requiring argument. Other matters are said to block reunification. One of these is Purgatory, for which EO does not even have a term, making a direct comparison difficult. We begin our analysis with the RC teachings on Purgatory, its locus, characteristics, and functions, and provide a simple relational network that shows Purgatory in relation to the afterlife, in particular to Heaven and Hell. With EO we begin with the teachings about life after death and provide a first approximation of Heaven and Hell and their relation to Paradise and Hades, both in characteristics and functions. Again, a simple relational network is enlightening. A surface comparison between the two networks distinguishes between those beliefs about the afterlife that are shared between RC and EO and those parts which house differences. It is these differences that must be subject to careful semiotic analysis to discover whether they are etic and possibly serious but not grounds for mutual excommunication or emic and a true barrier to reunification. We leave the possibly lengthy semiotic analysis for a subsequent study.

Line heating is a method used in the production of highly curved plates in the shipbuilding process. Line-heating process is generally regarded as one of the outdated technologies in the modernized and automated shipbuilding process. No piece of information in the line-heating process is either quantified or computerized. These drawbacks have restricted the automation of line-heating process and, as a result, the entire shipbuilding process. Therefore, a new automated line-heating process based on quantitative and computerized heating information has been sought. This paper describes a comprehensive algorithm for an automated line-heating process. By focusing on the overview of the complete algorithm, this paper integrates the components of the algorithm that have been separately published by the authors. The overall procedure of the automated line-heating process, including shell piece modeling, shell development, cylindrical approximation for curved plates, computation of heating information, and measurement and surface comparison, is discussed. The comprehensive algorithm is adjustable for different heat sources and measuring methods, without incurring fundamental changes in algorithm. The proposed line-heating algorithm has been implemented and transferred to some shipyards for customized applications. Simulation of automated line-heating facility

Abstract Motivation Global protein surface comparison (GPSC) studies have been limited compared to other research works on protein structure alignment/comparison due to lack of real applications associated with GPSC. However, the technology advances in cryo-electron tomography (CET) have made methods to identify proteins from their surface shapes extremely useful. Results In this study, we developed a new method called Farthest point sampling (FPS)-enhanced Triangulation-based Iterative-closest-Point (ICP) (FTIP) for GPSC. We applied it to protein classification using only surface shape information. Our method first extracts a set of feature points from protein surfaces using FPS and then uses a triangulation-based efficient ICP algorithm to align the feature points of the two proteins to be compared. Tested on a benchmark dataset with 2329 proteins using nearest-neighbor classification, FTIP outperformed the state-of-the-art method for GPSC based on 3D Zernike descriptors. Using real and simulated cryo-EM data, we show that FTIP could be applied in the future to address problems in protein identification in CET experiments. Availability and implementation Programs/scripts we developed/used in the study are available at http://ani.stat.fsu.edu/∼yuan/index.fld/FTIP.tar.bz2. Supplementary information Supplementary data are available at Bioinformatics online.
