    From quantum curves to topological string partition functions

    This paper describes the reconstruction of the topological string partition function for certain local Calabi-Yau (CY) manifolds from the quantum curve, an ordinary differential equation obtained by quantising their defining equations. Quantum curves are characterised as solutions to a Riemann-Hilbert problem. The isomonodromic tau-functions associated to these Riemann-Hilbert problems admit a family of natural normalisations labelled by topological types of the Fenchel-Nielsen networks used in the Abelianisation of flat connections. To each chamber in the extended K\'ahler moduli space of the local CY under consideration there corresponds a unique topological type. The corresponding isomonodromic tau-functions admit a series expansion of generalised theta series type from which one can extract the topological string partition functions for each chamber

    Retrospective Assessment of Animals Experimentation Projects in Romania – A Critical Analysis of Non-Technical Summaries

    The aim of the present inquiry was to design an overview about the non-technical summaries available on the web page of the National Sanitary Veterinary and Food Safety Agency (Romania). We analyzed the compliance to the requirement of replacement, reduction and refinement (the 3R’s). 56 projects were found, the most of them (48), were assigned as “basic research”, 2 as “translational and applied research”, 2 as “regulatory use and routine analysis”, while 4 projects targeted “higher education or training”. The most common animals species used were rats, and mice, followed by rabbits, pigs, hamsters, guinea pigs and frogs (Rana sp.). According to cumulative severity of the project, 20 projects were classified as “severe”, six as “moderate”, three “mild”, and three as “non-recovery”. 24 projects had nor a severity assessment, neither a proper description of the level of severity. In our opinion, the number of projects classified as “severe” is too high; at least for some of them, the level of severity could be reduced using appropriate pain control techniques and / or human end-points. Overall, our recommendation is further improving the knowledge and skills of the personal involved in authorization and execution of the projects and of the authority inspectors that authorized the projects

    Narrative construction of self-coherence in the virtual space

    While social psychologists warn us that the search for self-coherence brings cognitive biases, marketers and public relations specialists define consistency as the main ingredient of personal branding campaigns. Taking a moderate path, sociologists theorize self-coherence as a coping mechanism for rewriting self-biographies to colonize the future, assuming the narrative as a self-coherence inducing device. We considered the emergence of personal blogs as a suitable setting to study the narrative construction of the self during late modernity. We present a narrative constructivist analysis of data collected from personal blogs (the top 46 Romanian personal blogs in terms of popularity, and 100 blogs participating in a digital archiving memory project) in the period of emergence and unprecedented momentum. We found evidence of three narrative tactics for building self-coherence in the virtual space: temporal coherence, causal coherence, and thematic coherence
