Regional species diversity is explained ultimately by speciation, extinction and dispersal. Here, we estimate dispersal and speciation rates of Neotropicaal butterflies to propose an explanation for the distribution and diversity of extant species. We focused on the tribe Brassolini (owl butterflies and allies), a Neotropical group that comprises 17 genera and 108 species, most of them endemic to

An important challenge in the design and implementation of self-optimizing systems is that of finding a model that maps changes in a tunable parameter (or “knob”) into an effect on the performance, power, or energy, of the overall system. This paper describes ARPE (Analyzing the Relationship between Parameters and Effectors), an open source tool to analyze the effect of parameter changes on the be

Colloidal perovskite nanocrystals are building blocks for novel materials due to the property of nanocrystals to self-assemble into ordered structures (superlattices). Exemplified by a prototypical perovskite CsPbBr3, research into perovskite nanocrystal superlattices is motivated by reports of intriguing phenomena such as superfluorescence and superradiance.[1] Such cooperative luminescence arise

We have entered a monumental era in terms of realizing the impact of biodiversity loss on our everyday lives. We suffer from the consequences of biodiversity loss due to overexploitation of natural resources as we continue failing to restore biodiversity. One of the major consequences of biodiversity loss is the emergence of global pandemics. We are in urgent need of realizing the full potential o

This special issue presents findings from the ‘Conditioning Demand: Older People, Diversity, and Thermal Experience’ re- search project undertaken between 2011 and 2013. The aim of the project was to address the confluence of two key future trends: Europe's ageing population and the need to reduce domestic en- ergy consumption to counter rising utility prices and the in- creasing threat of climate

Anhand einer repräsentativen Umfrage unter Beschäftigten analysiert das vorliegende Paper die Zustimmung zu energiepolitischen Maßnahmen und die Wahrnehmung sozioökonomischer Folgen entlang politischer Parteipräferenzen. Zwischen den parteipolitischen Linien „Mitte links“ (SPD, Grüne, Die Linke), „Mitte rechts“ (CDU/CSU, FDP) und „populistisch“ (BSW, AfD) finden sich deutliche Unterschiede, aber ü

Global warming has drawn more and more attention from ICT industries to reduce the energy consumption of mobile cellular network recently. Lots of techniques to make the energy efficiency network, e.g. making the cell with low load switch off, have been proposed but less research on how to offer the Quality of Service(QoS) guarantee to the users which were connected to the off cell. Due to this fa

N-Oxyl mediated oxidations are becoming widely applied to the selective oxidation of a range of substrates bearing primary alcohol groups, including renewable biopolymers such as cellulose, but screening of mediators and oxidation conditions can be a laborious process, potentially limiting discovery of new mediators and/or optimised conditions for reaction. We describe a simple method for rapid vo

In today's world, there is an increasing trend towards the use of renewable, cheap and readily available biomass in the production of a wide variety of fine and bulk chemicals in different biorefineries. Biorefineries utilize the activities of microbial cells and their enzymes to convert biomass into target products. Many of these processes require enzymes which are operationally stable at high te

Engineering heat transfer problems are very often of a complex nature and most often no analytical solutions exist. One way to create solutions to such problems is to apply numerical methods. This study concerns heat transfer problems with coupled conduction, convection and thermal radiation. Five important but different engineering problems are considered: 1) The transient temperature distributi

This chapter provides a novel framework for assessing energy security and illustrates its application by the Global Energy Assessment, the IEA Model for Short-term energy security and in several studies of long-term global energy security.

The myogenic response is the intrinsic ability of small arteries to constrict in response to increased intraluminal pressure. Although microRNAs have been shown to play a role in vascular smooth muscle function, their importance in the regulation of the myogenic response is not known. In this study, we investigate the role of microRNAs in the regulation of myogenic tone by using smooth muscle-spec
