With 193 described species, Chusquea is the most diverse bamboo genus in the Neotropical region. Brazil, with 48 accepted species and 44 of them endemic, is one of its major centers of diversity. Among the Brazilian species, C. anelythra was only superficially characterized in its original publication almost 200 years ago, without a clear definition of its type-material, description of culm leaves, or comments on its geographic distribution or related species. As the absence of such information has greatly complicated the taxonomic delimitation of C. anelythra, the major aim of this paper is to clarify the identity of this species based on fieldwork and herbarium investigation, providing an emended description, illustrations, and photos of this species. We also designate a lectotype for the name C. anelythra, and provide a morphological comparison with two similar members of the C. meyeriana informal group. Geographic distribution and conservation status are also updated for this species.

Drepanolejeunea pinnatiloba Schiffn. (Lejeuneaceae) has only been collected once in Brazil, from a single population in the Atlantic Forest in southern Bahia state. Seventeen years later, we report the second record of D. pinnatiloba. This new record is from the Una Biological Reserve, also in southern Bahia. We discuss the geographic distribution and evaluate conservation status of this species for Brazil and the Neotropical region.

A New Species

Stachytarpheta grandiflora, an endemic species to campos rupestres of the Parque Nacional da Serra da Canastra, west of Minas Gerais, Brazil, is described and illustrated. The new species is characterized by pubescent branches, leaves with acute apex, petiole 0.5–1 cm long, bracts 0.7–1 cm long, with caudate apex, calyx 1.5–1.6 cm long, pubescent, 2-toothed and corolla 2.3–3 cm long, dark blue. It belongs to the informal group “Sellowiana”. We provide a detailed diagnosis, a morphological comparison with the most similar species, a key for the informal group where the new species belongs, a distribution map, conservation status and illustrations.

A New Species

The oribatid mite subgenus Scheloribates (Topobates) Grandjean, 1958, is recorded from the Neotropical region for the first time. A new species of this subgenus is described from the leaf litter collected in Cayo Agua Island, Panama. Scheloribates (Topobates) panamaensis sp. nov. differs from its related species by the very large body size and presence of a strong ventrodistal process on the leg femora II–IV.

The first flush phenomenon of urban wet weather discharges is presently a controversial subject. Scientists do not agree with its reality, nor with its influences on the size of treatment works. Those disagreements mainly result from the unclear definition of the phenomenon. The objective of this article is first to provide a simple and clear definition of the first flush and then to apply it to real data and to obtain results about its appearance frequency. The data originate from the French database based on the quality of urban wet weather discharges. We use 80 events from 7 separately sewered basins, and 117 events from 7 combined sewered basins. The main result is that the first flush phenomenon is very scarce, anyway too scarce to be used to elaborate a treatment strategy against pollution generated by urban wet weather discharges.

AbstractThe success of complex product development projects strongly depends on the clear definition of target factors that allow a reliable statement about the fulfilment of the product requirements. In the context of tolerancing and robust design, Key Characteristics (KCs) have been established for this purpose and form the basis for all downstream activities. In order to integrate the activities related to the KC definition into product development as early as possible, the often vaguely formulated requirements must be translated into quantifiable KCs. However, this is primarily a manual process, so the results strongly depend on the experience of the design engineer.In order to overcome this problem, a novel computer-aided approach is presented, which automatically derives associated functions and KCs already during the definition of product requirements. The approach uses natural language processing and formalized design knowledge to extract and provide implicit information from the requirements. This leads to a clear definition of the requirements and KCs and thus creates a founded basis for robustness evaluation at the beginning of the concept design stage. The approach is exemplarily applied to a window lifter.

Euphoria is by definition ambiguous. Some researchers have noted it is a cause for drug taking while others have viewed it as the effect of taking drugs, To date there is no clear definition of what “euphoria” is or how it enters into career drug use or abuse. This article proposes that “euphoria” is metaphoric, and on that basis may be learned. Learning to use drugs euphorically is the key to controlled drug use and ultimately the control of drug abuse.

With the rise of Deep Learning approaches in computer vision applications, significant strides have been made towards vehicular autonomy. Research activity in autonomous drone navigation has increased rapidly in the past five years, and drones are moving fast towards the ultimate goal of near-complete autonomy. However, while much work in the area focuses on specific tasks in drone navigation, the contribution to the overall goal of autonomy is often not assessed, and a comprehensive overview is needed. In this work, a taxonomy of drone navigation autonomy is established by mapping the definitions of vehicular autonomy levels, as defined by the Society of Automotive Engineers, to specific drone tasks in order to create a clear definition of autonomy when applied to drones. A top–down examination of research work in the area is conducted, focusing on drone navigation tasks, in order to understand the extent of research activity in each area. Autonomy levels are cross-checked against the drone navigation tasks addressed in each work to provide a framework for understanding the trajectory of current research. This work serves as a guide to research in drone autonomy with a particular focus on Deep Learning-based solutions, indicating key works and areas of opportunity for development of this area in the future.
