Dear Mark Lorenzen, I hope this email finds you well. We regretfully inform you that we have decided to withdraw our poster presentation from the upcoming DRUID conference (paper "Regional green-tech diversification and inter-regional green knowledge flows: EU evidence", co-authored with Sandro Montresor and Fabrizio Fusillo). Due to unforeseen circumstances and changes in our research timeline, we are unable to meet the conference deadline and present our work as planned. We apologize for any inconvenience caused and appreciate the opportunity given to us. Thank you very much for understanding. Kind regards, Adelia Fatikhova Gran Sasso Science Institue -- ______________________________________ adelia.fatikhova@gssi.it Tel: +39 329 359 3875
