Periapical bone edema volume in 3D MRI is positively correlated with bone architecture changes by Alexander W. Marka, Monika Probst, Tobias Greve, Nicolas Lenhart, Niklas Graf, Florian Probst, Gustav Andreisek, Thomas Frauenfelder, Matthias Folwaczny, Egon Burian

“…Materials and methods Patients with clinical evidence of apical periodontitis were included retrospectively and received OPT as well as MRI of the viscerocranium including a 3D-STIR and a 3D-T1 gradient echo sequence. Bone edema was visualized using the 3D-STIR sequence and periapical hard tissue changes were evaluated using the 3D-T1 sequence. …”

Acute haemodynamic impact of transcatheter aortic valve implantation in patients with severe aortic stenosis by Francesca Graziani, Pio Cialdella, Rosa Lillo, Gabriella Locorotondo, Lorenzo Genuardi, Gessica Ingrasciotta, Stefano Cangemi, Marialisa Nesta, Piergiorgio Bruno, Cristina Aurigemma, Enrico Romagnoli, Michele Calabrese, Nicole Giambusso, Antonella Lombardo, Francesco Burzotta, Carlo Trani

“…LHC after TAVI revealed significant changes in aortic and left ventricular (LV) pressures, including indexes of intrinsic myocardial contractility and diastolic function such as positive dP/dT (1128.9 ± 398.7 vs. 806.3 ± 247.2 mmHg/s, P ˂ 0.001) and negative dP/dT (1310.7 ± 431.1 vs. 1075.1 ± 440.8 mmHg/s, P ˂ 0.001). Post‐TAVI echo showed a significant reduction in LV end‐diastolic (P = 0.036) and end‐systolic (P ˂ 0.001) diameters, improvement in LV ejection fraction (from 55 ± 12% to 57.2 ± 10.5%, P ˂ 0.001), and pulmonary artery systolic pressure (42.1 ± 14.2 vs. 33.1 ± 10.7 mmHg, P < 0.001). …”

Enhancing deep learning methods for brain metastasis detection through cross-technique annotations on SPACE MRI by Tassilo Wald, Benjamin Hamm, Julius C. Holzschuh, Rami El Shafie, Andreas Kudak, Balint Kovacs, Irada Pflüger, Bastian von Nettelbladt, Constantin Ulrich, Michael Anton Baumgartner, Philipp Vollmuth, Jürgen Debus, Klaus H. Maier-Hein, Thomas Welzel

“…Abstract Background Gadolinium-enhanced “sampling perfection with application-optimized contrasts using different flip angle evolution” (SPACE) sequence allows better visualization of brain metastases (BMs) compared to “magnetization-prepared rapid acquisition gradient echo” (MPRAGE). We hypothesize that this better conspicuity leads to high-quality annotation (HAQ), enhancing deep learning (DL) algorithm detection of BMs on MPRAGE images. …”

Using WSR-88D Polarimetric Data to Identify Bird-Contaminated Doppler Velocities by Yuan Jiang, Qin Xu, Pengfei Zhang, Kang Nai, Liping Liu

“…In the first step, the fuzzy-logic method in the HCA is simplified and used to identify biological echoes (mainly from birds and insects). In the second step, another simple fuzzy logic method is developed to detect bird echoes among the biological echoes identified in the first step and thus remove bird-contaminated velocities. …”

A Convection Nowcasting Method Based on Machine Learning by Aifang Su, Han Li, Liman Cui, Yungang Chen

“…The addition of the optical flow information can more accurately simulate nonlinear trends such as the rotation, or merging, or separation of radar echoes. The trajectories of radar echoes obtained through nowcasting are closer to their actual movements, which prolongs the valid forecasting period and improves forecast accuracy.…”

Special MISO-SAR and MIMO-SAR Modes for Bidirectional Imaging by Hai Jiang, Hongjun Song, Lei Guo, Wei Wang

“…To suppress mutual interference, the two subpulses are transmitted with different range-frequency bands, and their echoes are demodulated and recorded in different channels in the proposed MIMO-SAR. …”

The use of sonar data for mapping the muddy bottom of water reservoir by Pastusiak Tadeusz

“…The goal of the work was to find a method to determine the structure of the subsurface of the bottom of a water reservoir with relatively soft ooze-muddy sediments using the recorded parameters of the first and second sonar echoes. This would allow avoiding the use of expensive devices such as sub-bottom profilers.…”

Dystopia, surveillance and the spaces of social control in Jenni Fagan’s The Panopticon (2012) by Claire Wrobel

“…Although the text explicitly reappropriates the Panopticon designed by Jeremy Bentham (1748-1832), an invention itself riven by the tension between utopia and dystopia, and echoes Michel Foucault’s strategic reading in Discipline and Punish (1975), the virulent critique it levels at the welfare state echoes some of the central issues to be found in George Orwell's attack on totalitarian states, particularly those related to memory and language. …”
