Generalist species are core components of ecological networks and crucial for the maintenance of biodiversity. Generalist species and networks are expected to be more resilient, and therefore understanding the dynamics of specialization and generalization in ecological networks is a key focus in a time of rapid global change. Whilst diet generalization is frequently studied, our understanding of h

The issue of museum entrance fees is widely debated. Traditionally, it has been commonly agreed that museums should be free, however nowadays charged admission is the norm. Although economic analysis is a relevant tool in order to understand the impact of a given admission policy on museum demand the notion of congestion has been previously overlooked. In this essay, I analyze how museum visitatio

Modern tourists visited traditional tourist sights seeking the extraordinary in the place. In a post tourism era, tourists seek authentic experiences looking for the extraordinary in themselves which they express through their self-performance on social media. Different stakeholders are communicating the brand, which means a loss of brand control for the destination brand managers. The purpose of

Det har skett stora förändringar i resebeteendet, inte minst under covidpandemin. Det ökade intresset för att resa inom landet förväntas bestå och ett lands varumärke samt identitet spelar en betydande roll för turistnäringen. Globaliseringen gör det allt svårare att differentiera sig som land, samtidigt som multikulturella befolkningar erbjuder nya möjligheter och utmaningar. Den här studien undeThere have been major changes in travel behavior, primarily due to the COVID-19 pandemic. The increased interest in domestic travel is expected to continue and the brand and identity of nations play a significant role in the tourism industry. Furthermore, globalization presents challenges for nations when differentiating themselves on the market, at the same time as multicultural populations offer

Is the language and terminology used in the Church of Sweden understandable to young people? Many scientists have investigated the religiosity of youth and the liturgical language, but there is no completed study on the relationship between the language that young people use in discussions about existential issues and the language of the representatives of the Church of Sweden. This study examine

This paper presents stability theory of adaptive systems using an extension of the Yakubovich-Kalman-Popov (YKP) lemma. Adaptive stability analysis is relevant for observer-based feedback control systems. Relaxation of the controllability and observability conditions imposed in the YKP lemma can be made for a class of adaptive systems described by a linear time-invariant system (LTI) with adaptive

We show that the observer-backstepping technique applied to linear control object and combined with linear control system design gives rise to a non-standard composition of control object, observer and controller. The resultant system is characterized by a full-order observer and a reduced-order control system design which in its complexity does not go beyond the `relative degree' of the control o

This contribution is about an entirely new approach to the study of knowledge. As an introductory remark, the classical research operations in the field of cognition are reviewed. Against this background, an application of David Hestenes theory of rotational dynamics is demonstrated with particular reference to text processing. Based on the mechanism of joints and links of the AaO machine, angular

This paper compares two hardware design flows, based on the classic VHDL on one side and the relatively new Bluespec System Verilog (BSV) on the other side. The comparison is based on a case study of a Java embedded architecture, comprising a Java native processor and a memory management unit. The processor is a micro-programmed, pipelined, Java-optimized processor (JOP), initially written in VHDL

Vassilevska and Williams (STOC 2009) showed how to count simple paths on k vertices and matchings on k/2 edges in an n-vertex graph in time n^{k/2+O(1)}. In the same year, two different algorithms with the same runtime were given by Koutis and Williams (ICALP 2009), and Björklund et al. (ESA 2009), via nst/2+O(1)-time algorithms for counting t-tuples of pairwise disjoint sets drawn from a given fa

We show that for any ε > 0, a maximum-weight triangle in an undirected graph with n vertices and real weights assigned to vertices can be found in time O(nω + n2+ε), where ω is the exponent of fastest matrix multiplication algorithm. By the currently best bound on ω, the running time of our algorithm is O(n2.376). Our algorithm substantially improves the previous time-bounds for this problem recen
