Electri. anapoles, ari.i.g from the destructi.e i.terference of pri.i.i.e and toroi.al electri. di.ole moments, have recently emerged as a fundamental class of non-scatteri.g sources. On the other hand, super-scatteri.g states represent the opposi.e regi.e wherei. the scatteri.g cross-secti.n of a subwavelength parti.le exceeds the si.gle-channel li.i., leadi.g to a strong scatteri.g behavi.r. Here, we demonstrate that the i.terplay between the topology of li.ht and the subwavelength scatterer can lead to these two opposi.e responses wi.hi. an i.olated alldi.lectri. meta-atom. i. parti.ular, we present the emergence of a new non-scatteri.g state, referred to as hybri. anapole, whi.h surpasses conventi.nal electri. di.ole anapoles by achi.vi.g a remarkable 23-fold enhancement i. the suppressi.n of far-fi.ld radi.ti.n and almost threefold enhancement i. the confi.ement of electromagneti. energy i.si.e the meta-atom. We also explore the role of parti.le ori.ntati.n and i.s i.versi.n symmetry i. the scatteri.g response and predi.t the possi.i.i.y of swi.chi.g between non-scatteri.g and super-scatteri.g states wi.hi. the same platform. The presented study eluci.ates the role of li.ht and matter topologi.s i. the scatteri.g response of subwavelength meta-atoms, uncoveri.g two opposi.e regi.es of li.ht-matter i.teracti.n and openi.g new avenues i. appli.ati.ns such as nonli.ear opti.s and spectroscopy.

One of the bi.gest dangers to soci.ty today i. terrori.m, where attacks have become one of the most si.ni.i.antri.ks to i.ternati.nal peace and nati.nal securi.y. Bi. data, i.formati.n analysi., and arti.i.i.l i.telli.ence (Ai. havebecome the basi. for maki.g strategi. deci.i.ns i. many sensi.i.e areas, such as fraud detecti.n, ri.k management,medi.al di.gnosi., and counter-terrori.m. However, there i. sti.l a need to assess how terrori.t attacks are related,i.i.i.ted, and detected. For thi. purpose, we propose a novel framework for classi.yi.g and predi.ti.g terrori.tattacks. The proposed framework posi.s that neglected text attri.utes i.cluded i. the Global Terrori.m Database(GTD) can i.fluence the accuracy of the model’s classi.i.ati.n of terrori.t attacks, where each part of the datacan provi.e vi.al i.formati.n to enri.h the abi.i.y of classi.i.r learni.g. Each data poi.t i. a multi.lass taxonomyhas one or more tags attached to i., referred as “related tags.” We appli.d machi.e learni.g classi.i.rs to classi.yterrori.t attack i.ci.ents obtai.ed from the GTD. A transformer-based techni.ue called Di.ti.BERT extracts andlearns contextual features from text attri.utes to acqui.emore i.formati.n from text data. The extracted contextualfeatures are combi.ed wi.h the “key features” of the dataset and used to perform the fi.al classi.i.ati.n. Thestudy explored di.ferent experi.ental setups wi.h vari.us classi.i.rs to evaluate the model’s performance. Theexperi.ental results show that the proposed framework outperforms the latest techni.ues for classi.yi.g terrori.tattacks wi.h an accuracy of 98.7% usi.g a combi.ed feature set and extreme gradi.nt boosti.g classi.i.r.
