Radiation risks and uncertainties: a scoping review to support communication and informed decision-making
Authors: Hoti Ferdiana , Perko Tanja , Thijssen Peter , Renn Ortwin 
Published: May 2020

Abstract
Although radiation protection is challenged by many uncertainties, there is no systematic study investigating the definitions and types of these uncertainties. To address this gap, in this paper we offer a scoping review to comprehensively analyse, for the first time, peer-reviewed scientific articles (n = 33) related to uncertainties in the following radiation exposure situations: nuclear emergencies, decommissioning of nuclear/radiological installations and long-term radiological exposure situations (e.g. naturally occurring radioactive materials). The results suggest that firstly, there is no agreement regarding definitions of uncertainty, which is mainly defined based on its sources, types or categories rather than by its meaning. Secondly, different actors are faced with different types of uncertainties. Uncertainties of the scientific community are mostly data and methodology-driven (e.g. dose-response relationships), those of the decision-makers are related to the likely consequences of decision options and public reactions, while laypeople’s uncertainties are mainly related to the trustworthiness of experts or the emotional potential of specific risk exposures. Furthermore, the majority of articles focus on the uncertainties of the scientific community, while those of the information receivers (i.e. decision-makers and laypeople) receive much less consideration. Finally, there was no difference in types of uncertainties across the different risk-related study areas analysed (radiation versus other risks). Based on these findings, we provide some preliminary recommendations regarding research on uncertainty related to radiation protection, as well as communication practices.
A quantum active learning algorithm for sampling against adversarial attacks
Authors: Casares P A M , Martin-Delgado M A 
Published: May 2020

Abstract
Adversarial attacks represent a serious menace for learning algorithms and may compromise the security of future autonomous systems. A theorem by Khoury and Hadfield-Menell (KH), provides sufficient conditions to guarantee the robustness of active learning algorithms, but comes with a caveat: it is crucial to know the smallest distance among the classes of the corresponding classification problem. We propose a theoretical framework that allows us to think of active learning as sampling the most promising new points to be classified, so that the minimum distance between classes can be found and the theorem KH used. Additionally, we introduce a quantum active learning algorithm that makes use of such framework and whose complexity is polylogarithmic in the dimension of the space, m, and the size of the initial training data n, provided the use of qRAMs; and polynomial in the precision, achieving an exponential speedup over the equivalent classical algorithm in n and m.
Effects of weak disorder on the thermalization of Fermi–Pasta–Ulam–Tsingou model
Authors: Sun Lulu , Zhang Zhenjun , Tong Peiqing 
Published: May 2020

Abstract
We study the effects of two kinds of weak disorders on the thermalization of the Fermi–Pasta–Ulam–Tsingou model by extensive numerical simulations. The disorders are introduced to the mass of atom or coefficient of the quadratic term of potential energy. The initial energy is distributed equally among some lowest frequency modes. We find that the energy transports to high-frequency modes with time t and eventually approaches energy equipartition faster with either weak disorder than that in the homogeneous case. That means weak disorders accelerate the process of thermalization. We further study the effects of two kinds of disorders on the scaling law of equipartition time T
eq. We find that T
eq satisfies the following scaling law: T
eq ∼ (ɛ)−a
(|α|)−b
for different disorder strengths in the thermodynamic limit. It is found that the exponent a ≈ 1.0 while b depends on the strength of disorder, which are different from b = 2a in the homogeneous case.
Non-equilibrium phase separation with reactions: a canonical model and its behaviour
Authors: Li Yuting I , Cates Michael E 
Published: May 2020

Abstract
Materials undergoing both phase separation and chemical reactions (defined here as all processes that change particle type or number) form an important class of non-equilibrium systems. Examples range from suspensions of self-propelled bacteria with birth–death dynamics, to bio-molecular condensates, or ‘membraneless organelles’, within cells. In contrast to their passive counterparts, such systems have conserved and non-conserved dynamics that do not, in general, derive from a shared free energy. This mismatch breaks time-reversal symmetry and leads to new types of dynamical competition that are absent in or near equilibrium. We construct a canonical scalar field theory to describe such systems, with conserved and non-conserved dynamics obeying model B and model A, respectively (in the Hohenberg–Halperin classification), chosen such that the two free energies involved are incompatible. The resulting minimal model is shown to capture the various phenomenologies reported previously for more complicated models with the same physical ingredients, including microphase separation, limit cycles and droplet splitting. We find a low-dimensional subspace of parameters for which time-reversal symmetry is accidentally recovered, and show that here the dynamics of the order parameter field (but not its conserved current) is exactly the same as an equilibrium system in which microphase separation is caused by long-range attractive interactions.

Mobile Devices and Mobile Apps Use among Indonesian College Students
Authors: Pratama Ahmad R. 
Published: May 2020

Abstract
This article adds more insights into the previous study about the use of mobile apps on smartphones and tablets among Indonesian college students based on a survey of undergraduate students at one private university in Indonesia. Data analysis includes two-sample tests of proportion and multiple correspondence analysis (MCA). The findings confirm social media as not only the most frequently used app category, but also with the highest level of engagement. While most students use their mobile device mostly for social media, it is regular and heavy use of educational apps that are more closely tied to spending more than five hours per day on mobile device whereas more frequent mobile gaming is associated to more hours spent on mobile device. Students from IT major were found to be an anomaly among other STEMM disciplines. Not only they are more likely to spend more hours on their mobile device, but also, they tend to be more socially active, at least digitally and not necessarily physically in daily life. The findings in this study give a better understanding of how Indonesian students use their mobile device that was already uncovered in the previous study by answering some of the remaining questions.
Experimental evaluation of the effect of cryogenic treatment of brake discs of the vehicle on the performance characteristics
Authors: Dygalo V , Zhukov I , Diakov A , Chutkov K 
Published: May 2020

Abstract
The article presents the conclusions and prerequisites of the experimental evaluation of friction pairs in the aspect of fading. The most part of kinetic energy of the vehicle with ABS is extinguished at the expense of friction work in the brake mechanism. Thus, the overheating of the brake mechanism, namely its pair of friction is peculiar to vehicles not equipped with ABS (for example, ATV) and leads to the phenomenon of critical fading, accompanied by a sharp decrease in braking torque. The reduction of the influence of this phenomenon is a very difficult task in terms of both taking into account the cost of the braking mechanism and its minimal complication. The authors suggest the use of cryogenic processing of brake disks to reduce the impact of thermal loading on the emergence of fading.

Authors: Kotiev G , Padalkin B , Miroshnichenko A , Stadukhin A , Kositsyn B 
Published: May 2020

Abstract
The article deals with the problem of the characteristics selection for the electric motors of the drivetrains of the high-speed tracked vehicles with individually driven sprockets. The existing method of the tracked vehicle cornering dynamics analysis is not suitable for the analysis of the motion at the speeds near to the critical speeds in the skidding mode. The authors offer a method for improving the accuracy of the existing analytical dependencies by the use of neural network. The above-mentioned improvements provide estimation of the limit values of the required traction forces on the sides of the vehicle but they do not allow gathering statistical data on the electric motor operating conditions of short and long duration during the vehicle operation. The authors offer to solve this problem by means of a driving simulation complex. The complex provides simulation of the tracked vehicles driving along stochastic routes in real time mode and collection of the stochastic data on the electric motor loads.
The method of increasing the stability of trailer-trucks in case of emergency braking in a turn and emergency failure of the trailer brake system
Authors: Zhileykin M , Skotnikov G 
Published: May 2020

Abstract
One of the most important properties of semi-trailer trucks are stability and steerability. This is because with an increase in driving speeds, these properties largely determine the safety of vehicle operation. Improving the semi-trailer trucks safety is all the more relevant because the consequences of road accidents involving semi-trailer trucks are the most severe and cause enormous damage. One of the most common causes of accidents is the loss of stability during emergency braking in a turn, especially in the event of a failure of trailer braking system. The goal of this research is to develop principles for improving the stability of semi-trailer trucks movement during emergency braking in a turn and failure of trailer braking system. A method has been developed to increase semi-trailer trucks stability during emergency braking in a turn and the failure of trailer braking system, which allows to maintain the trajectory stability of the semi-trailer truck and to avoid accidents with severe consequences. Using simulation methods, the effectiveness of the proposed method is proved.

Analysis of the centrifugal pump operation inunsteady modeas apart of a mobile machine
Authors: Protopopov A , Anisimova A , Mukhlaeva A , Kalugina M , Babikova D 
Published: May 2020

Abstract
Mobile vehicles, both tracked and wheeled, are often used to refuel/unload stationary tanks. In this case, the unsteady mode of operation of such centrifugal pumps is often observed. A constant change of operation conditions, in particular the static component of the pump head, leads to a change in its operating mode, as a result of which most of the time the pump operates in off-design mode. A methodology has been developed for determining the actual pump efficiency for a tank filling-draining cycle with two variable parameters: the distance from the level of the pumped fluid in the well to the bottom of the tank (to the on float) and the tank height (or the distance between on and off floats).

The cacao peels activated using 50% H3PO4at the temperature of 400 °C for 1 hour. Scanning Electron Microscopy was applied for a surface analysis of activated carbon, and the functional groups identified by Fourier Transform Infra-Red (FTIR). The adsorption process was carried out by a column methodwith a flow rate variation of 5 mL/min and 10 mL/min. The results showed that by using 2 grams of actived carbon with a flow rate of 5 mL/min is the optimum condition, with the obtained absorption efficiency of 91.8% BOD, 90.2% COD, and 96.5% color. Morphological analysis has determinedthe changes in pore on the surface of activated carbon. Analysis of functional groups showed that the produced activated carbon hada pattern of absorption with OH, CH, and CO type of bond. Based on the results, it can be concluded that the activated carbon of cacao peels can improve the quality of dirty well water, and make it consumable for the daily use.

Abstract
Patients with symptoms of arrhythmias must live a healthy lifestyle and routinely conduct consultations and control the heart rate with the doctor. The most important of these is an integrated health monitoring tool. In this study a portable heart rate monitoring tool is proposed for patients at risk of low-cost IoT-based alert systems using a telegram messager. The ESP8266 Wifi module functions for communication to the web server gateway and pulse sensor to detect heart rates that converted to Bits per Minute (BPM). The heart rate data is then stored in the database server using TCP / IP communication — heartbeat information in realtime with Android display. The system alert will send to the doctor/health worker and family if the heart rate is below 60 BPM and above 100 BPM, the time required for sending system alerts with a telegram messager is around 6 to 7 seconds. Test results show an average error of the heart rate measurement of 4.75% and the entire system is running well. With this tool the patient is at risk of being able to work more safely, and the doctor and family are easier to supervise the patient.
