Humor styles have been found to be associated with well-being, however, no study has addressed the distinct well-being associations of combinations of humor styles, that is, humor types, yet. The present study thus aimed at investigating which combinations of humor styles exist and to which extent these humor types are associated with well-being. In an online questionnaire, the Humor Styles Questionnaire (HSQ, Martin et al. J Res Pers 37:48–75, 2003), self-regulatory strategies, self-esteem, and well-being instruments were administered to a German sample. Exploratory and confirmatory factor analyses replicated the underlying structure of the HSQ. With hierarchical clustering, we found evidence for three humor types (endorsers, humor deniers, and self-enhancers), which differed in group means for self-esteem, self-regulatory strategies, and well-being. Findings provide further evidence for the positive well-being correlates of self-enhancing humor, and distinctly address the positive correlates of aggressive and self-defeating humor being absent. It is discussed that humor styles cannot be conceptualized as beneficial or detrimental per se, but have to be regarded in context. [less ▲]

Biological wastewater treatment plants (BWWTPs) based on the activated sludge (AS) pro- cess have dramatically improved worldwide water sanitation despite increased urbanization and industrialization. However, current AS-based operations are considered economically and environmentally unsustainable. In this Perspective, we discuss our current understanding of microbial populations and their metabolic transformations in AS-based BWWTPs in view of developing more sustainable processes in the future. In particular, much has been learned over the course of the past 25 years about specialized microorganisms, which could be more comprehensively leveraged to recover energy and/or nutrients from wastewater streams. To achieve this, we propose a bottom-up design approach, focused around the concept of a “wastewater biorefinery column”, which would rely on the engineering of distinct ecological niches into a BWWTP in order to guarantee the targeted enrichment of specific organismal groups which in turn will allow the harvest of high-value resources from wastewater. This concept could be seen as a possible grand challenge to microbial ecologists and engineers alike at the centenary of the discovery of the AS process. [less ▲]

The work investigates the feasibility of massive MIMO in SatCom. Towards this, the necessary channel models, system parameters and scenarios are identified and a basic simulator developed. The work then considers an efficient implementation of the massive MIMO transmission through the use of hybrid analog/digital precoder. Efficient algorithmic solutions are proposed for the partially connected precoder architecture which enables efficiency in power/ hardware complexity and its performance evaluated. [less ▲]

Recent advances in Milimeter wave (mmWave) band mobile communications may provide solutions to the increasing traffic demand in modern wireless systems. Even though mmWave bands are scarcely occupied, the design of a prospect transceiver should guarantee the efficient coexistence with the incumbent services in these bands. To that end, in this paper, two underlay cognitive transceiver designs are proposed based on a hybrid Analog/Digital transceiver architecture that enables the mmWave spectrum access while controlling the interference to the incumbent users with low hardware complexity and power consumption. The first cognitive solution designs a codebook free cognitive hybrid pre-coder by maximizing the mutual information between its two ends subject to interference, power and hardware constraints related to the analog counterpart. The second solution is codebook based and exhibits less complexity than the first one at the cost of inferior spectral efficiency. A novel codebook free solution for the post-coder at the cognitive receiver part is further proposed, based on a hardware constrained Minimum Mean Square Error criterion. Simulations study the performance of both the proposed hybrid approaches and compare it to the one of a fully digital solution for typical wireless environments. [less ▲]

Hybrid Analog/Digital (A/D) pre-/post-coding solutions aim at the reduction of the hardware complexity and power consumption of a system employed with a large-scale antenna array functioning in the millimeter (mmWave) band. This is achieved by enabling the transceiver design with fewer Radio Frequency (RF) chains than antennas. In this work, hybrid A/D transceiver designs are developed for a relay assisted mmWave system that aims at data transmission from a source to a destination node via the well-known amplify-and-forward cooperative protocol. To that end, hybrid solutions are proposed for the joint design of the source and relay nodes precoders and for the destination ones, as well. Contrariwise to existing literature approaches that develop codebook-based solutions and exhibit limitations on the performance, the proposed approaches are codebook-free and present significantly improved spectral efficiency, as it is verified via the presented simulations.

This paper argues for a hybrid approach to historical research that combines ’traditional’ with digital hermeneutical approaches in a new practice of doing history. As the digital turn alters and affects all parts of the historical research process, this is a pressing challenge and need for all historians, not just for those engaged in ‘big data’ projects. Indeed, hybridity is, and should be, the new normal. Yet while most historians are accustomed to deploying digital approaches in the information gathering stage of their research, they often refrain from ‘going digital’ in its processing and especially analysis stages. Describing a number of digital tools used in work done on the diaries of Anne frank, the paper critically analyses and demonstrates the added value of incorporating them in all stages of historical research. Digital approaches enhance the methodological repertoire furnished by ‘traditional’ close reading practices. Hybrid approaches thus expand our intellectual horizons and the analytical power we bring to bear upon our sources. [less ▲]
