Fallacia is distinguished morpho‐anatomically from Navicula sensu lato based on the possession of an H‐shaped chloroplast, lateral sterna and a finely porous conopeum, but whether this genus is monophyletic is still in question. Three new Fallacia species are described based on morphology and SSU rRNA and rbcL gene sequences: Fallacia tateyamensis sp. nov., Fallacia bosoensis sp. nov. and Fallacia laevis sp. nov. We performed the first comprehensive molecular and morphological phylogenetic analyses of 31 Fallacia species based on 11 new sequences from six species and 23 morphological characters. We also documented the detailed morphogenesis of Fallacia for the first time. Fallacia is not monophyletic. Both morphological and DNA sequence data supported the separation of Rossia from Fallacia, while the phylogenetic position of Pseudofallacia is uncertain. We recognized four morphogroups in Fallacia by morphological and molecular phylogenetic analyses. Ancestral character reconstruction indicated that diatoms in Sellaphoraceae evolved from the possession of two lateral narrow parallel depressions covered by narrow nonporous conopea, to lyre‐shaped canals covered by wide porous conopea. Lanceolate canals and the presence of areolae in canals evolved multiple times independently. [ABSTRACT FROM AUTHOR]

Over the past decade, enhanced computing capabilities and mobile technologies have begotten the upsurge of innovative mobile health (mHealth) solutions, and many research efforts have occurred recently in the area of technology-based interventions (TBI) for autism spectrum disorders (ASD). Mobile augmented reality (MAR) refers to AR systems that use the handheld mobile device medium (mobile phones, tablets or smart glasses). This article reports the results of a systematic review undertaken on the use of MAR for ASD-related skills learning from the year 2010. It aims to provide an insight into the current state of research on MAR interventions and to provide guidance to relevant designers and researchers. We searched seven databases and retrieved 625 articles initially. After exclusion and screening, 36 articles were reviewed reporting on using MAR to improve various skills of children and adolescents with ASD, and 10 research questions related to PICO (P: Population, I: Intervention, C: Comparison, O: Outcomes) were addressed. This study identifies challenges that still exist in the research efforts towards the development of applications exploiting the MAR for ASD interventions: technology issues, research design consideration, subjective assessment etc. The studies examined suggest researchers should focus on users and improve the quality of the MAR app. In addition, more effective research methods and evaluation methods could be involved in future studies to facilitate the development of MAR intervention applications.
