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...

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...

Large-scale shell-model calculations for the even-even cadmium isotopes Cd-98-Cd-108 have been performed with the ANTOINE code in the pi(2p(1/2); 1g(9/2)).(2d(5/2); 3s(1/2); 2d(3/2); 1g(7/2); 1h(11/2)) model space without further truncation. Known experimental energy levels and B(E2) values could be well reproduced. Taking these calculations as a s...
In this paper, an energy model is developed customised for the design of low carbon energy systems on business park scale. The model comprises two sequential stages: In the first stage, heat recovery within the system is maximised, while utility system and energy storage are optimally integrated and designed to fulfil remaining energy requirements ...
Anammox has shown its promise and low cost for removing nitrogen from high strength wastewater such as landfill leachate. A reactor was inoculated with nitrification-denitrification sludge originating from a landfill leachate treating waste water treatment plant. During the operation, the sludge gradually converted into red Anammox granular sludge ...
