“…In 1936, Dr Bentami rejected the Blum-Viollette Project by asserting that the Muslims 'prefer to remain subjects under the folds of the French tricolour than be free citizens under the German or Russian boot'. 81 In a meeting celebrating Doriot's visit to Algiers in May 1938, Victor Arrighi declared that what was lacking above all else in Algeria was a leader, one who could inspire both love and discipline in the Muslim population:…”

If any element of colonial Algerian society can be seen to embody a commitment to the logic of elimination at the heart of settler colonialism, it is, perhaps, the extremeright. With its unabashed defence of European supremacy and its enthusiastic celebration of the military and agricultural conquest of the land, the interwar extremeright was steeped in the tropes of settler colonial politics. Nevertheless, its embrace of both the discourse and the practices typical of political movements in settler colonial polities was hampered by the demographic and political realities of colonial rule in French Algeria. In particular, the rise of indigenous political movements in the colony and the election of the Popular Front in the metropole would force the extreme right to move beyond its traditional politics grounded in anti-Semitism and celebrations of settler hegemony. In this paper, I examine the complex blend of strategies pursued by movements of the extreme right in Algeria to expand their support among the settler population while also seeking to establish a limited foothold among the indigenous population. I contend that the leadership of these organisations sought to reconcile these seemingly contradictory goals by combining the evocation of cruder forms of settler hegemony with a more sophisticated and politically palatable defence of exclusion rooted in the rhetoric of French republican imperialism. I ask if this concession to the political norms of the metropole should be understood as a distinctive feature that places the specific settler colonial context of Algeria and the politics practiced there outside of the theoretical and analytical categories proposed by settler colonial theory.

“…Endovascular interventions have been embraced by interventional radiologists and vascular surgeons to reduce the surgical impact related to open surgery. At the same time, many other disciplines introduced endovascular procedures with applications in paediatrics [ 1 ], cardiology [ 2 , 3 ], neurology [ 4 ], and oncology [ 5 , 6 ].…”

Optimised passive marker device visibility and automatic marker detection for 3-T MRI-guided endovascular interventions: a pulsatile flow phantom study

et al. 2022

Background Passive paramagnetic markers on magnetic resonance imaging (MRI)-compatible endovascular devices induce susceptibility artifacts, enabling MRI-visibility and real-time MRI-guidance. Optimised visibility is crucial for automatic detection and device tracking but depends on MRI technical parameters and marker characteristics. We assessed marker visibility and automatic detection robustness for varying MRI parameters and marker characteristics in a pulsatile flow phantom. Methods Guidewires with varying iron(II,III) oxide nanoparticle (IONP) concentration markers were imaged using gradient-echo (GRE) and balanced steady-state free precession (bSSFP) sequences at 3 T. Furthermore, echo time (TE), slice thickness (ST) and phase encoding direction (PED) were varied. Artifact width was measured and contrast-to-noise ratios were calculated. Marker visibility and image quality were scored by two MRI interventional radiologists. Additionally, a deep learning model for automatic marker detection was trained and the effects of the parameters on detection performance were evaluated. Two-tailed Wilcoxon signed-rank tests were used (significance level, p < 0.05). Results Medan artifact width (IQR) was larger in bSSFP compared to GRE images (12.7 mm (11.0–15.2) versus 8.4 mm (6.5–11.0)) (p < 0.001) and showed a positive relation with TE and IONP concentration. Switching PED and doubling ST had limited effect on artifact width. Image quality assessment scores were higher for GRE compared to bSSFP images. The deep learning model automatically detected the markers. However, the model performance was reduced after adjusting PED, TE, and IONP concentration. Conclusion Marker visibility was sufficient and a large range of artifact sizes was generated by adjusting TE and IONP concentration. Deep learning-based marker detection was feasible but performance decreased for altered MR parameters. These factors should be considered to optimise device visibility and ensure reliable automatic marker detectability in MRI-guided endovascular interventions.
