Universal Fingerprint Generation: Controllable Diffusion Model with Multimodal Conditions.

The utilization of synthetic data for fingerprint recognition has garnered increased attention due to its potential to alleviate privacy concerns surrounding sensitive biometric data. However, current methods for generating fingerprints have limitations in creating impressions of the same finger with useful intra-class variations. To tackle this challenge, we present GenPrint, a framework to produce fingerprint images of various types while maintaining identity and offering humanly understandable control over different appearance factors such as fingerprint class, acquisition type, sensor device, and quality level.

PrintsGAN: Synthetic Fingerprint Generator.

A major impediment to researchers working in the area of fingerprint recognition is the lack of publicly available, large-scale, fingerprint datasets. The publicly available datasets that do exist contain very few identities and impressions per finger. This limits research on a number of topics, including e.

Haematopoietic stem cell transplantation: a comparison between the accreditation process performed by competent authorities and JACIE in Italy.

There have been great advances over the last decades in haematopoietic stem cell (HSC) transplantation, using either bone marrow, peripheral blood or cord blood-derived stem cells. The coming into force of the European legislation on tissues and cells and the consequent transposition of Directives into national laws have required the health authorities in the Member States (MS) and the scientific societies to review the transplantation activities to ensure the circulation of safe HSC products. Here, the regulatory inspection process performed by the Competent Authorities and the professional voluntary accreditation process of the Transplant Programmes active in Italy is compared.

CoCo: a web application to display, store and curate ChIP-on-chip data integrated with diverse types of gene expression data.

Motivation: CoCo, ChIP-on-Chip online, is an open-source web application that supports the annotation and curation of regulatory regions and associated target genes discovered in ChIP-on-chip experiments. CoCo integrates ChIP-on-chip results with diverse types of gene expression data (expression profiling, in situ hybridization) and displays them within a genomic context. Regulatory relationships between the transcription factor-bound regions and putative target genes can be stored and expanded throughout different sessions.

Resonant effects in compound diffraction gratings: Influence of the geometrical parameters of the surface.

We explore and discuss the influence of the geometrical parameters of a compound diffraction grating on the generation of pi resonances, which appear when the surface is illuminated by a p-polarized plane wave. We consider a grating with rectangular grooves, and analyze the evolution of pi resonances when depth, width, distance between grooves, and period of the grating are varied. In particular, we performed a detailed study for a grating with five grooves per period, and found that there are certain values of the geometrical parameters that optimize the enhancement of the electromagnetic field inside the corrugations.
