In [MT2] the Vafa-Witten theory of complex projective surfaces is lifted to oriented $\mathbb C^*$-equivariant cohomology theories. Here we study the K-theoretic refinement. It gives rational functions in $t^{1/2}$ invariant under $t^{1/2}\leftrightarrow t^{-1/2}$ which specialise to numerical Vafa-Witten invariants at $t=1$. On the "instanton bran...

Research question: Understanding corporate social responsibility (CSR) implementation requires identifying factors that contribute to the ability of a sport organisation to develop CSR. This paper examines the complex combination of organisational factors associated with CSR implementation in a sport federation (SF) setting. Thus, this study identi...
We study competitive dynamics by using 10 years of data from the biotech industry on patent infringement lawsuits because they capture offensive actions and defensive responses. Results suggest that larger patent portfolios, long-term partnerships, and short-term agreements lead to factor market rivalry. Specifically, long-term research partnership...
We propose a definition of Vafa–Witten invariants counting semistable Higgs pairs on a polarised surface. We use virtual localisation applied to Mochizuki/Joyce–Song pairs. For KS≤0 we expect our definition coincides with an alternative definition using weighted Euler characteristics. We prove this for degKS
OBJECTIVE: To describe mandibular premolar root and canal morphology and its variability in Chilean and Belgian samples using cone-beam computed tomography. METHODS: A cross-sectional and descriptive study was conducted. A total of 402 mandibular premolars were examined using cone-beam computed tomography images of Chilean and Belgian patients. Pre...
In this paper, a solar double absorption heat transformer (SDAHT) operating with the LiBr-H2O solution is proposed to provide high temperature energy. The flat plate collector (FPC) is used to supply the demanded heat input in the present configuration, which will greatly broaden the application scope of the FPCs. The thermo-economic concept is app...
