ST‐SIGMA: Spatio‐temporal semantics and interaction graph aggregation for multi‐agent perception and trajectory forecasting
Authors: Fang Yang , Luo Bei , Zhao Ting , He Dong , Jiang Bingbing , Liu Qilie 
Published: November 2022

AbstractScene perception and trajectory forecasting are two fundamental challenges that are crucial to a safe and reliable autonomous driving (AD) system. However, most proposed methods aim at addressing one of the two challenges mentioned above with a single model. To tackle this dilemma, this paper proposes spatio‐temporal semantics and interaction graph aggregation for multi‐agent perception and trajectory forecasting (ST‐SIGMA), an efficient end‐to‐end method to jointly and accurately perceive the AD environment and forecast the trajectories of the surrounding traffic agents within a unified framework. ST‐SIGMA adopts a trident encoder–decoder architecture to learn scene semantics and agent interaction information on bird’s‐eye view (BEV) maps simultaneously. Specifically, an iterative aggregation network is first employed as the scene semantic encoder (SSE) to learn diverse scene information. To preserve dynamic interactions of traffic agents, ST‐SIGMA further exploits a spatio‐temporal graph network as the graph interaction encoder. Meanwhile, a simple yet efficient feature fusion method to fuse semantic and interaction features into a unified feature space as the input to a novel hierarchical aggregation decoder for downstream prediction tasks is designed. Extensive experiments on the nuScenes data set have demonstrated that the proposed ST‐SIGMA achieves significant improvements compared to the state‐of‐the‐art (SOTA) methods in terms of scene perception and trajectory forecasting, respectively. Therefore, the proposed approach outperforms SOTA in terms of model generalisation and robustness and is therefore more feasible for deployment in real‐world AD scenarios.
Robust transmission design for artificial noise aided multiuser broadcast system in inaccurate channel state information scenario with users of different importance
Authors: Yao Li , Liu Youjiang , Zhang Jian , He Yudong 
Published: November 2022

AbstractIn this article, robust beamforming (BF) and artificial noise (AN) design method is proposed for multiuser broadcast secure transmission under secrecy outage probability (SOP) constraints. A special scenario is assumed that the transmitter cannot obtain the accurate channel state information (CSI) of the users' channel, and different users have different priorities and importance. This special scenario makes traditional BF algorithms and AN design methods unable to guarantee the effective and secure transmission of information. To deal with intractable non‐convex problems in this new design, a series of optimization methods like Bernstein‐type inequality (BTI) and S‐Procedure are employed to transform these problems into solvable functions. Moreover, a search algorithm is explored for simplifying the computational complexity of the optimization algorithm. After that, the new robust algorithm is compared with former methods in inaccurate CSI scenarios by numerical simulation, which shows the advantages of our algorithm.
A screen‐shooting resilient document image watermarking scheme using deep neural network

Published: November 2022

AbstractWith the advent of the screen‐reading era, the confidential documents displayed on the screen can be easily captured by a camera without leaving any traces. Thus, this paper proposes a novel screen‐shooting resilient watermarking scheme for document image using deep neural network. By applying this scheme, when the watermarked image is displayed on the screen and captured by a camera, the watermark can be still extracted from the captured photographs. Specifically, the scheme is an end‐to‐end neural network with an encoder to embed watermark and a decoder to extract watermark. During the training process, a distortion layer between encoder and decoder is added to simulate the distortions introduced by screen‐shooting process in real scenes, such as camera distortion, shooting distortion, and light source distortion. Furthermore, a background sensitive loss and a lpips loss are used to improve visual quality of the watermarked document images in the training process. Besides, a strength factor adjustment strategy is also designed to improve the visual quality with little loss of bit extraction accuracy. The experimental results show that the proposed scheme has higher visual quality and robustness than the other two recent state‐of‐the‐art methods.
Modeling the 2020 November 29 solar energetic particle event using EUHFORIA and iPATH models

Published: November 2022

Aims.We present the implementation of a coupling between EUropean Heliospheric FORcasting Information Asset (EUHFORIA) and improved Particle Acceleration and Transport in the Heliosphere (iPATH) models. In this work, we simulate the widespread solar energetic particle (SEP) event of 2020 November 29 and compare the simulated time-intensity profiles with measurements at Parker Solar Probe (PSP), the Solar Terrestrial Relations Observatory (STEREO)-A, SOlar and Heliospheric Observatory (SOHO), and Solar Orbiter. We focus on the influence of the history of shock acceleration on the varying SEP time-intensity profiles and investigate the underlying causes in the origin of this widespread SEP event.Methods.We simulated a magnetized coronal mass ejection (CME) propagating in the data-driven solar wind with the EUHFORIA code. The CME was initiated by using the linear force-free spheromak module of EUHFORIA. The shock parameters and a 3D shell structure were computed from EUHFORIA as inputs for the iPATH model. Within the iPATH model, the steady-state solution of particle distribution assuming diffuse shock acceleration is obtained at the shock front. The subsequent SEP transport is described by the focused transport equation using the backward stochastic differential equation method with perpendicular diffusion included.Results.We examined the temporal evolution of shock parameters and particle fluxes during this event and we find that adopting a realistic solar wind background can significantly impact the expansion of the shock and, consequently, the shock parameters. Time-intensity profiles with an energetic storm particle event at PSP are well reproduced from the simulations. In addition, the simulated and observed time-intensity profiles of protons show a similar two-phase enhancement at STA. These results illustrate that modeling a shock using a realistic solar wind is crucial in determining the characteristics of SEP events. The decay phase of the modeled time-intensity profiles at Earth is in good agreement with the observations, indicating the importance of perpendicular diffusion in widespread SEP events. Taking into account the possible large curved magnetic field line connecting to Solar Orbiter, the modeled time-intensity profiles show a good agreement with the observation. We suggest that the broadly distorted magnetic field lines, which are due to a stream interaction region, may be a key factor in helping to improve our understanding of the observed SEPs at Solar Orbiter for this event.

Authors: Henes Joerg Christoph , Saur Sebastian 
Published: November 2022

ZusammenfassungDie beiden Großgefäßvaskulitiden unterscheiden sich in
mehrfacher Hinsicht, vor allem aber durch das Alter der betroffenen Patienten
bei Erstmanifestation. Die Riesenzellarteriitis (RZA) ist eine Erkrankung des
älteren Patienten wohingegen die Takayasu Arteriitis per definitionem
vor dem 40 Lebensjahr auftritt. Die Diagnosen sind in den letzten Jahren durch
verbesserte Bildgebung und Therapieoptionen mehr ins Bewusstsein
gerückt. Neben der klassischen Steroidtherapie – welche bis
heute Mittel der ersten Wahl ist – steht uns mit Tocilizumab, einem
monoklonalen Antikörper gegen IL6-Rezeptor, zumindest für die
RZA, eine zusätzliche hocheffektive Therapie zur Verfügung.
Andere vielversprechende Substanzen befinden sich derzeit in Erprobung. Dieser
Artikel soll einen Überblick zu Diagnostik und Therapie, aber auch einen
Ausblick zu möglicherweise kommenden medikamentösen Optionen
bieten.
Bedarfsorientierte kognitiv-behaviorale Intervention für
Paare mit Infertilität (FERTIFIT): Eine Pilotstudie zur Entwicklung,
Durchführbarkeit und Akzeptanz
Authors: Yamanaka-Altenstein Misa 
Published: November 2022

Zusammenfassung
Einleitung Weltweit schwankt die Prävalenz für
Infertilität zwischen 4–17% und in westlichen
Ländern ist rund eins von sieben Paaren mit Kinderwunsch betroffen. Das
Erleben einer Infertilität ist mit einer erhöhten
Wahrscheinlichkeit für psychische und partnerschaftliche Belastungen
assoziiert, wobei sich Partner einer Paarbeziehung in ihrem Befinden gegenseitig
beeinflussen. Dennoch ist die Versorgungslücke für betroffene
Paare groß. In dieser Pilotstudie wird eine praktikabel umsetzbare,
bedarfsorientierte und kognitiv-verhaltenstherapeutische Intervention
für Paare mit Infertilität vorgestellt, die die
partnerschaftliche Bewältigung typischer Problembereiche fördern
und einer zunehmenden Belastung entgegenwirken soll.
Material und Methoden Insgesamt nahmen 21 heterosexuelle Paare an dieser
Studie mit Eigen-Warte-Kontrollgruppendesign teil. Die Intervention beinhaltete
bedarfsabhängig 5–10 paartherapeutische Sitzungen. Die
psychische und infertilitätsbedingte Belastung, die
Partnerschaftsqualität, sowie die Anwendung von individuellen und
partnerschaftlichen Ressourcen wurden zu vier Messzeitpunkten (M1=vor
Wartekontrollphase, M2=vor Intervention, M3=nach Intervention,
M4=nach Katamnese) mittels Fragebögen erhoben.
Ergebnisse Bei Frauen besserten sich die psychische und
infertilitätsbedingte Belastung, und sie griffen auf mehr Ressourcen
zurück, die zum Wohlbefinden und zur aktiven Problembewältigung
und Emotionsregulation beitragen. Während des Interventionszeitraumes
kam es bei Männern zu einem zunehmenden Erleben hilfreicher
Unterstützung, und sowohl bei Männern als auch bei Frauen zu
einem häufigeren Einsatz partnerschaftlicher Copingstrategien. Die
Evaluation zeigte, dass die Teilnehmenden sehr zufrieden waren mit der
Intervention insgesamt und mit der erhaltenen Unterstützung.
Diskussion Die Befunde deuten auf eine gute Durchführbarkeit und
Akzeptanz dieser Intervention in der psychotherapeutischen Praxis hin und
liefern erste Hinweise auf mögliche erwünschte Effekte, die
allerdings aufgrund des Studiendesigns und der vorliegenden Limitationen nicht
eindeutig auf die Intervention zurückgeführt werden
können.
Schlussfolgerung Die Stärke der vorliegenden Studie liegt in der
Vorstellung eines in der psychotherapeutischen Praxis gut anwendbaren
paartherapeutischen Konzepts, das bedarfsgerecht angeboten werden kann.
Für die Überprüfung der gefundenen Effekte ist eine
anschließende größer angelegte klinische Studie mit
randomisiert-kontrolliertem Design notwendig.

Published: November 2022

AbstractInstability and dislocation can occur in up to one in four cases following revision total hip arthroplasty (THA), and optimal placement of components is critical in avoiding re-revision. Computer-assisted navigation can improve accuracy and precision of component placement in primary THA; however, its role in revision surgery is not defined. The purpose of our study was to evaluate the effect of computer-assisted navigation on component placement in revision THA. This study was a retrospective, multicenter cohort of 128 patients (69 imageless navigation, 59 conventional) who underwent revision THA between March 2017 and January 2019. An imageless computer navigation device was utilized in 69 of the 128 patients. Acetabular component placement and the proportion placed in a functional safe zone were compared between navigation-assisted and conventional THA groups. Mean anteversion increased significantly in both the navigation group (18.6 ± 8.5 degrees vs. 21.6 ± 7.8 degrees, p = 0.03) and the control group (19.4 ± 9.6 degrees vs. 21.2 ± 9.8 degrees, p = 0.03). Postoperatively, the proportion of acetabular components within the safe zone in the navigation group (inclination: 88%, anteversion: 84%) was mildly improved over the control group (83 and 69%, respectively). Variance in inclination improved significantly in both the control (50.6 vs. 112.4 degrees, p = 0.002) and navigation (46.2 vs. 141.1 degrees, p < 0.001) groups. Anteversion variance worsened in the control group (96.3 vs. 87.6 degrees, p = 0.36) but the navigation group showed improvement (61.2 vs. 72.7 degrees, p = 0.25). Postoperative variance was significantly better in the navigation group compared to the control group (p = 0.04). Utilizing imageless navigation in revision THAs results in more consistent placement of the acetabular component as compared to nonnavigated revision surgeries.

Published: November 2022

AbstractThe purpose of this study was to describe the care of intubated patients in pediatric critical care. Acknowledging there are several perceived factors that contribute to unplanned extubations, a secondary objective was to describe how practice variation may relate to observed differences in unplanned extubation rates. A survey about practices related to the care of intubated patients was distributed to all pediatric intensive care units (PICUs) participating in the Virtual Pediatric Systems (VPS, LLC). Unplanned extubation rates for 2019 to 2020 were obtained from VPS. Univariate and bivariate analyses were performed to describe the responses, with unplanned extubation rates calculated as means. The text responses about perceived causes of unplanned extubation in participants' sites were explored using thematic content analysis. A total of 44 PICUs were included in this study (response rate 37.0%). The mean unplanned extubation rate for the sample was 0.41 (95% confidence interval: 0.31–0.50) per 100 intubation days. Variability was found across several aspects that impact care, including staffing, the frequency of procedures (e.g., chest radiography), and treatment-related goals (e.g., sedation and mobilization). The perceived causes of unplanned extubations in the sample included patient-, staff-, and equipment-related factors. We found practice variability in pediatric critical care units related to the care of intubated patients, which may contribute to the frequency of adverse events. As evidence emerges and professional associations and organizations recommend the best practices, knowledge translation will be required for the implementation and deimplementation of practices to improve the quality of care in PICUs.

AbstractThe first robotic colectomy was performed 20 years ago. Since that time, the robotic surgery platform has made significant advancements and become increasingly prevalent in colorectal surgery. The da Vinci Xi system (Intuitive Surgical, Sunnyvale, CA) and technology such as integrated table motion has facilitated multiquadrant procedures.Intracorporeal anastomoses (ICAs) have proven benefit in the literature, including decreased length of stay, decreased narcotic requirements, and lower rate of postoperative wound infections and hernias. Additional studies have shown a lower conversion to open rate in robotic surgery compared with laparoscopy. In this article, we will describe techniques for creation of robotic ICAs.

Published: November 2022

AbstractA 7-year-old girl with recurrent episodes of pancreatitis with risk factor of poorly controlled hyperglyceridemia presented with an acute episode of pancreatitis. She was managed conservatively and underwent whole exome sequencing which showed a likely pathogenic LPL gene mutation. Incidentally, she was diagnosed with COVID-19 on screening, which we hypothesize to have triggered the recent episode. On further examination, she was found to have bilateral cataracts. Her hypercholesterolemia was effectively managed with dietary therapy, high dose omega 3, and gemfibrozil. Our case report sensitizes the clinician to use a modern diagnostic tool such as whole exome sequencing in children with recurrent pancreatitis where hypertriglyceridemia is a known risk factor. This child is the first case of LPL mutation reported in India.

Published: November 2022

AbstractAnastomotic leaks remain a dreaded complication after ileal pouch anal anastomosis (IPAA). Their impacts can be devastating, ranging from an acute leak leading to postoperative sepsis to chronic leaks and sinus tracts resulting in long-term pouch dysfunction and subsequent pouch failure. The management of acute leaks is intricate. Initial management is important to resolve acute sepsis, but the type of acute intervention impacts long-term pouch function. Aggressive management in the postoperative period, including the use of IV fluids, broad-spectrum antibiotics, and operative interventions may be necessary to preserve pouch structure and function. Early identification and knowledge of the most common areas of leak, such as at the IPAA anastomosis, are important for guiding management. Long-term complications, such as pouch sinuses, pouch-vaginal fistulas, and diminished IPAA function complicate the overall survival and functionality of the pouch. Knowledge and awareness of the identification and management of leaks is crucial for optimizing IPAA success.

Published: November 2022

AbstractUp to 30% of patients with ulcerative colitis (UC) will require surgical management of their disease during their lifetime. An ileal pouch-anal anastomosis (IPAA) is the gold standard of care, giving patients the ability to be free from UC's bowel disease and avoid a permanent ostomy. Despite surgical advancements, a minority of patients will still experience pouch failure which can be debilitating and often require further surgical interventions. Signs and symptoms of pouch failure should be addressed with the appropriate workup and treatment plans formulated according with the patient's wishes. This article will discuss the identification, workup, and treatment options for pouch failure after IPAA.

Published: November 2022

AbstractMay–Thurner syndrome (MTS) is a relatively rare vascular condition that is characterized by external compression of the left common iliac vein by the right common iliac artery against the fifth lumbar vertebra. This condition slows the blood flow and is a predisposing factor for deep vein thrombosis (DVT). The key to its successful treatment is to remove the clot and fix the anatomical lesion. If this MTS diagnosis is missed, the recurrence of thrombosis will lead to significant morbidity and mortality. We report a case of 70-year-old female who had left leg DVT caused by MTS and was treated with catheter-directed thrombolysis along with long-term anticoagulation.
