Abstract
Chorus waves play a key role in outer Van Allen electron belt dynamics through cyclotron resonance. Here, we use Van Allen Probes data to reveal a new and distinct population of intense chorus waves excited in the heart of the radiation belt during the main phase of geomagnetic storms. The power of the waves is typically ∼2-3 orders of magnitude greater than pre-storm levels, and are generated when fluxes of ∼10-100 keV electrons approach or exceed the Kennel-Petschek limit. These intense chorus waves rapidly scatter electrons into the loss cone, capping the electron flux to a value close to the limit predicted by Kennel and Petschek over 50 years
ago. Our results are crucial for understanding the limits to radiation belt fluxes, with accurate models likely requiring the inclusion of this chorus wave-driven flux-limiting process, that is independent of the acceleration mechanism or source responsible for enhancing the flux.

Abstract
Background: This paper studied retrospectively the dosimetry and therapeutic accuracy of deep inspiration breath hold (DIBH) radiotherapy in regional nodal radiation (RNI)-containing right-sided breast cancer patients who had completed treatment based on surface guided radiotherapy (SGRT) technology, hoping to clarify the clinical application value and related issues .
Methods: Free breath (FB) and DIBH plans were prepared for31 RNI-containing right breast cancer patients who had completed DIBH radiotherapy based on SGRT technology. Four organs at risk (OARs) including heart, right coronary artery (RCA), right lung and liver were made dosimetriccomparison on the premise that the planning target volume was met dose-volume prescription requirements. Meanwhile, 31 patients were divided into edge of xiphoid process (EXP), sternum middle (SM)and left breast wall (LBW) groups according to different positions of respiratory gating primary points. The CBCT setup error data of the three groups were contrasted for the treatment accuracy study, and the effects of different gating window heights on the lung volume increment of the right side were compared among the three groups.
Results: All planning target volume met the dose-volume coverage criteria. Compared with FB, DIBH slumpedthe maximum dose of heart and RCA by 44.3% and 46.7% respectively. The mean dose was went down by 12.5% for right lung. The mean liver dosedecreased the most, with an average reduction rate of 69.4%. The setup error of EXP group in the anterior-posterior (AP) direction was 3.6±4.5mm, significantly higher than the other two groups (2.2±2.6mm, 2.4±3.1mm). The rightlung volume increment in EXP, SM and LBW groups was 72.3%, 69.9 % and 67.2%, respectively(P=0.08), and the corresponding breath-holding heights were 13.5±3.7mm, 10.3±2.4mm, and 9.6±2.8mm, respectively(p<0.05).
Conclusions: SGRT-based DIBH can better protect the heart, RCA, ipsilateral lung and liver of right breast cancer patients combined with RNI. Different respiratory gating primary points have different therapeutic accuracy and breath-hold height. On the premise of reasonable respiratory gating primary points, interfractions can be widely applied as it has high repeatability and breath-holding stability to ensure therapeutic accuracy.
A note on how public transport announcements affect the spread of coronavirus
Authors: Heluo Yuxi , Robson Charles W. 
Published: October 2022

Abstract

We investigate the relationship between coronavirus-preventive announcements in public transport hubs and the spread of the coronavirus in Vienna, Austria. Due to its frequent high population densities, the role of public transport is a crucial topic in the field of public health, especially during times of pandemic. Using structural equation modeling, we analyze Google mobility data taken from February to December 2020 and find that changes in the contents of the announcements can influence the pandemic crisis, via their effects on public transport mobility. Interestingly, we find that different announcements affect public transport mobility differently. The impact of these announcements is maintained even after taking the effect of the contemporary government regulations into account. We therefore argue that, in order to fight the spread of the virus, it is important for policymakers to inform the general public about coronavirus-preventive behavior in an appropriate manner. We further suggest that governments take advantage of the large daily flow of people through public transport infrastructure, to disseminate vital information during crises.
DGL22: A practical Quantum key distribution
Authors: Al-darwbi Mohammed , Ghorbani Ali , Lashkari Arash 
Published: October 2022

Abstract
Quantum key distribution (QKD) protocols are unconditionally secure, providing that quantum devices are truthful. Device-independent quantum key distribution (DI-QKD) protocols offer the prospect of distributing secret keys with minimal assumptions. The DI-QKD protocols are hard to implement using the current technologies as they require all the quantum devices to be uncharacterized. Measurement device independent quantum key distribution (MDI-QKD) protocols assume that the measurement devices are not truthful; the adversary might make them. MDI-QKD is secure but more challenging to implement. Receiver-device-independent quantum key distribution (RDI-QKD) protocols assume that the receiver's measurement devices can be viewed as a black box while the sender's device can be trusted. RDI-QKD relies on reasonable assumptions that make it easy to implement using the current state-of-the-art technology. We propose an RDI-QKD protocol, called DGL22. DGL22 is secure against all known attacks that are allowed by quantum mechanics. DGL22 provides several benefits over previous protocols, including the capability to attain high communication and sifting efficiency.
Post-processing climate projections of precipitation for the Po river basin: will Italy's North become water-constrained?
Authors: Boyko Oleksiy , Reggiani Paolo , Todini Ezio 
Published: October 2022

Abstract
Surface and groundwater resource availability depends on precipitation patterns. Climatic change may alter not only future annual totals of precipitation but also its temporal distribution. In regions depending strongly on snow accumulation for steady water supply, this can lead to water constraints. We process climatic projections of precipitation from 19 models of the Climate Model Inter-comparison Project 5 for the Po river, Italy. The study area hosts Italy's most important lakes and reservoirs and is inhabited by 16 million people. The river basin is also known for its productive areas of irrigated agriculture. We apply a Bayesian processor of uncertainty, which we calibrate on a comprehensive set of high-resolution gridded observations. The processor outputs predictive densities of precipitation for selected prognostic time windows. These densities can be used in conjunction with an utility function to estimate potential losses and/or evaluate the benefits of mitigating actions. For the study area, annual precipitation will not change notably in the future for both an optimistic and a pessimistic scenario. The temporal distribution of precipitation will become affected. These potential changes result in considerable strain on storage capacity and water flows needed to satisfy irrigation demand as well as hydroelectric and thermal energy production.

Published: October 2022

Un papel fundamental de los diferentes modelos de extensión agropecuaria es la generación de procesos empresariales a través de propuestas asociativas y organizacionales entre medianos y pequeños productores. Conocer cuál ha sido el desarrollo de estas organizaciones permite establecer oportunidades de mejoramiento que beneficien su estructura y función, fortaleciendo su capital social y comercial. El objetivo de la investigación fue caracterizar los agroemprendimientos rurales a través del análisis de información secundaria y la recolección de datos en campo aportados por directivos e integrantes de la organización para conocer su situación actual y sus necesidades de fortalecimiento. Para ello, se utilizó una investigación de enfoque mixto con estatus dominante cualitativo y de tipo concurrente. La caracterización de los agroemprendimientos se realizó por medio del análisis de información secundaria, entrevistas semiestructuradas y grupos focales, que permitieron la identificación de los aspectos claves que inciden sobre las iniciativas empresariales, vistos desde cinco categorías de análisis —técnica, económica, social, comercial y organizacional—, las cuales facilitaron la aproximación a los múltiples factores que giran en torno a estos modelos de negocio y su influencia en el sector rural. La intervención permitió identificar aspectos fundamentales en el proceso de consolidación de una organización, encontrando similitudes con lo reportado en la literatura; además, favoreció el diagnóstico del territorio y el impacto social y empresarial del agroemprendimiento sobre la comunidad, identificando los aspectos que consideran relevantes para el desarrollo de sus capacidades de autogestión y sostenibilidad, y construyendo así una herramienta participativa para la identificación de las necesidades reales que involucran al actor real de las intervenciones de extensión agropecuaria. En conclusión, la propuesta participativa para la caracterización de los agroemprendimientos permitió generar un alto grado de apropiación por parte de los actores claves del territorio, autorreflexionando sobre factores que influyen en su funcionamiento y haciendo un recorrido desde sus capacidades para la identificación de debilidades y oportunidades. Esta forma de intervención favorece que la comunidad no solo identifique sus necesidades, sino que también se vincule en la creación de propuestas que movilicen sus recursos y estrategias hacia la consolidación y la sostenibilidad.
Deep 3D Dynamic Object Detection towards Successful and Safe Navigation for Full Autonomous Driving
Authors: Wijesekara Patikiri Arachchige Don Shehan Nilmantha 
Published: October 2022

Background:
Infractions other than collisions are also a crucial factor in autonomous driving since other infractions can result in an accident. Most existing works have been conducted on navigation and collisions; however, fewer studies have been conducted on other infractions such as off-road driving and not obeying road signs. Furthermore, state-of-the-art driving models have not performed dynamic 3D object detection in the imitation learning stage; hence, the performance of such a model is unknown. No research has been conducted to investigate the driving models' computational complexities.

Objective:
The objective of this research is to study the effect of 3D dynamic object detection for autonomous driving and derive an optimized driving model with superior performance for navigation and safety benchmarks.

Methods:
We propose two driving models. One of them is an imitation learning-based model called Conditional Imitation Learning Dynamic Objects (CILDO), which performs dynamic object detection using image segmentation, depth prediction, and speed prediction. The other proposed model is an optimized model of the base model using an additional traffic light detection branch and deep deterministic policy gradient-based reinforcement learning called Conditional Imitation Learning Dynamic Objects Low Infractions-Reinforcement Learning (CILDOLI-RL).

Results:
An ablation study proves that using image segmentation and depth prediction together to enable three-dimensional object vision improves navigation performance rather than taking decisions entirely from the image. The CILDOLI-RL model presented in this paper achieves the highest score for the newly introduced No-Other-Infraction benchmark and No-Crash benchmark. It scores a moderate score for the Car Learning to Act (CARLA) benchmark in both the training town and the testing town, ensuring safe autonomous driving. The base CILDO model achieves the best performance in navigation and moderate scores for safety benchmarks under urban or rural dense traffic environments in both towns. Both proposed models are relatively computationally complex.

Conclusion:
For safety-critical driving, since both navigation performance and safety are crucial factors, it can be concluded that the proposed CILDOLI-RL is the best model out of the two proposed models. For applications where driving safety is not of much concern, the proposed CILDO is the best model.
Studying effectiveness of channel jamming protection in aeronautical radio communications

Published: October 2022

When performing aviation flights the high-quality and reliable communication with the control room becomes important for ensuring the crew safety. The purpose of the study is to investigate the quality of aviation radio communication in different methods of information transmission for developing the technical solutions of radio communication perfection. The equipment used today is designed for instant selection of preset channels and data exchange at fixed operating frequencies of ground control points with aircraft radio equipment in the meter and decimeter ranges. The most important requirement for the aviation radio communication systems is to ensure a high level
of noise immunity including protection against active interference. There is considered the process of frequency changing, or frequency hops, as the most successful at the first stage of the study in order to find the least interference-prone operating frequency. The use of pseudorandom frequency changing of radio communication between the ground control points and aircraft radio equipment is studied as one of the ways of leveling interference effects. To increase the stability of the radio line, it is necessary to use digital methods of information transmission. The use of digital methods of encoding information leads to low-level errors in the processes of discretization, modulation, amplification, demodulation and filtering. Due to this, nonlinear quantization allows for a higher level of signal-to-noise ratio. With a constant power level of the transmitter it is possible to carry out stable communication even at higher values
of the signal-to-interference ratio, which generally leads to the increasing radio transmission range. Using highly robust coding methods, the probability of error can also be reduced. There are studied different parameters reflecting the quality of information transmission over the radio channel: speech intelligibility, probability of erroneous reception of symbols. Thus, the digital methods of information transmission have higher noise immunity compared to the analog ones, even without special protection measures. Using special measures (noise-proof coding, pseudorandom frequency changing) can significantly increase the jamming protection of the radio communication system.

Published: October 2022

O presente artigo tem por objetivo compreender como duas motoristas de cargas perigosas e passageiros narram os desafios enfrentados em profissões majoritariamente ocupadas por homens. A partir da coleta de dados por meio de entrevistas não estruturadas, foi empregada a análise de narrativas para compreender o conteúdo das falas das entrevistadas. Desta forma, destacam-se todas as dificuldades que as mulheres enfrentam ao decorrer dos anos nas profissões que a sociedade classifica como masculinas. Assim, demonstramos que as motoristas narram os julgamentos que as colocam como incapazes de exercer profissões majoritariamente masculinas. Questões como assédio também são percebidas neste contexto e podem transitar entre assédio moral e sexual. Ademais, as mulheres são constantemente questionadas quanto as suas escolhas por profissões que culturalmente são masculinizadas, vencendo essas percepções por meio da persistência. Este estudo contribui para ampliar as discussões a respeito das assimetrias de gênero, em que as mulheres ficam limitadas a um repertório de profissões legitimadas como adequadas ao gênero, bem como dar voz as lutas que perduram a séculos por igualdade de gênero.
