Let NDTIME(f(n),g(n)) denote the class of problems solvable in O(g(n)) time by a multi-tape Turing machine using an f(n)-bit non-deterministic oracle, and let DTIME(g(n)) = NDTIME(0, g(n)). We show that if the all-pairs shortest paths problem (APSP) for directed graphs with N vertices and integer edge weights within a super-exponential range { -2Nk+o(1),.,2Nk+o(1)}, k≥1 does not admit a truly subc

Policymakers increasingly emphasize knowledge collaboration between academia and society as important means to generate innovations and solve complex issues. However, while recent literature on such collaboration suggests that knowledge needs to be integrated and generated across disciplines and sectors, there are surprisingly few studies that define what is meant by ‘knowledge’ or focus on the pr

The transient electromagnetic (TEM) method is widely used in resistivity mapping but rarely applied in monitoring experiments. In this study, we present an algorithm to invert time-lapse TEM data, with inversion of both synthetic data and field data. Three main novelties distinguish this new inversion algorithm: i) a multiple-mesh approach is used for the definition of model parameters and forward

PurposeDoctoral candidates possess specialized knowledge that could support sustainability transitions. Doctoral education, however, often focusses on discipline-specific topics and working methods, making it difficult to “see the bigger picture”. This summer school on wood construction gathered doctoral candidates from different fields to explore how solutions to complex sustainability issues cou

When adopting the view of the multinational corporation (MNC) as a transnational corporation, subsidiaries become strategic partners. It is important to recognize that within the MNC knowledge may originate also from subsidiaries and thus flow in different directions. The aim of the article is to understand the role of multiple knowledge flows when international retail firms enter new markets. A q

Research on retail internationalization and internationalization in general acknowledges the relevance of knowledge management and organizational learning, even though there is a lack of discussion about the specific constructs and approaches that would be most fruitful. The central role of knowledge sharing in the internationalization process is rarely stressed. Furthermore, the specificities of

In this paper, we describe Docforia, a multilayer document model and application programming interface (API) to store formatting, lexical, syntactic, and semantic annotations on Wikipedia and other kinds of text and visualize them. While Wikipedia has become a major NLP resource, its scale and heterogeneity makes it relatively difficult to do experimentations on the whole corpus. These experimenta

BACKGROUND: Type 2 diabetes is one of the leading causes of chronic kidney failure, which increases globally and represents a significant threat to public health. People from the Middle East represent one of the largest immigrant groups in Europe today. Despite poor glucose regulation and high risk for early-onset insulin-deficient type 2 diabetes, they have better kidney function and lower rates

Background: Accumulating evidence suggests that statins have a beneficial effect on breast cancer prognosis. Previous studies have reported a positive association between statin use and breast cancer survival; however, the relationship between statin use and patterns of breast cancer recurrence remains unclear. Patients and methods: We identified all Malmö Diet and Cancer Study (MDCS) participants

The social restrictions during the covid-19 pandemic have challenged many aspects of preschool everyday life. Particularly vulnerable to these restrictions is the aspect of introducing new children to preschool, since preschool introduction constitutes a natural arena for establishment of preschool staff’s relationships with children and their parents. Based on analysis of open-ended survey data (

Det finns inte fler än ungefär femton fräkenväxter i hela världen. Men under karbon- och permtiden för ungefär 300 miljoner år sedan var de mycket vanliga, och mycket större.

A larger amount of older people need to participate in working life due to the global demographic change. It is the employer, through the manager, who enables employees to have access to measures in the workplace that facilitate and enable a sustainable extended working life. The aim of this study was to evaluate work life factors associated with managers believing their employees can work versus

Market frictions, such as imperfect information or hassle costs, may reduce benefits from market incentives in healthcare settings. We use data from two randomised policy interventions in a Swedish region, which improved the access to provider information and reduced the switching costs of one percent of the adult population and of a sample of new residents. We examine the effects of the intervent
