Special Issue Information

Dear Colleagues,

We are pleased to announce a new Special Issue collection of the journal of Symmetry entitled “Symmetry/Asymmetry in Neuromorphic and Intelligent Photonics”, for which we are collecting research articles, review articles, and short communications.

Recently, photonic materials and devices have attracted significant interest because they possess remarkable properties, such as the ability to reproduce nonlinear operations underlying learning and information storage.

Thus, researchers have started to explore the potential applications of these promising photonics materials to realize intelligent systems capable of replicating the neuronal dynamics typical of intelligent brain tissue.

This Special Issue aims to showcase contributions from researchers and thinkers in all realms of neuromorphic materials focusing on the symmetry and asymmetry properties and welcoming theoretical, experimental, and review contributions from physicists, biologists, material scientists, mathematicians, doctors, and engineers alike who are engaged and interested in this fast-growing field. All papers will be published in an open access format following peer review.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The rapid identification of bacteria is extremely important for controlling infections and enabling swift and effective action. Light scattering has proven to be a highly versatile technique for identifying bacteria, as it does not require long colony growth times. In this article, we present a study on the use of cross-polarized optical scattering (CPS). Despite a relatively low scattering efficiency (10−5 to 10−6), working with cross-polarization enhances contrast by eliminating a highly intense background of scattered light. CPS has been applied to four bacteria, with three similar in shape. Moreover, two of them are Gram+ and two Gram-. The obtained images have been reduced in size down to a 16-bit images and camera noise has been added. Although bacteria are symmetrical in principle, in reality rotations of their orientation generate asymmetries in the CPS patterns that were exploited precisely to recognize and classify the different species. The classification of bacteria by a t-SNE algorithm in a reduced-dimension space shows that their features are grouped into specific clusters. However, such classification is not completely decisive due to partial cluster overlapping. Full article
