A Taxonomy of Radiofrequency Jamming and Spoofing Strategies and Criminal Motives
Authors: Westbrook Tegg
Published: June 2023

This article provides a taxonomy of radiofrequency (RF) jamming and spoofing tactics and strategies associated with specific criminal objectives. This is based on the fact that the motivations and strategies of cyber-attackers – predominantly financial – is well-known, but the motivations behind specific electromagnetic interferences is lacking in the current literature. Previous research has also overlooked the motivations of other actors using jamming and spoofing devices.

The objective is to identify the most desirable spoofing and jamming strategies, likely targets, and likely motivations. The article finds that (a) previous literature on the subject overlooks a number of non-state actor motives, and therefore this research aims to fill this gap in knowledge; (b) out of 8 actors identified, denial of service attacks (7 out of 8), as well as so-called decoy spoofing (6), trojan spoofing (5), and jamming-enabled crime (5) are the most desirable strategies utilized; (c) out of 11 strategies identified, grey and black hat hackers (11 out of 11), terrorists (11) and activists (8), are likely to take advantage of most identified.
Extended Space Deterrence: Providing Security Assurance in Space
Authors: Kang Kiseok Michael
Published: June 2023

Many U.S. allies are increasingly dependent on space-based platforms for their military and economic activities. At the same time, the counterspace threats from U.S. adversaries such as China and Russia are rapidly intensifying. The United States has provided extended deterrence to its allies through its overwhelming nuclear and conventional capabilities for decades. The question arises as to whether the time-tested logic of extended deterrence is applicable in the space domain. This research argues that U.S. extended deterrence in space—relying on the traditional mechanism of deterrence-by-punishment—is ineffective due to the unique nature of outer space.
Positive orientation and health behaviors in older patients with atherosclerosis
Authors: Suppan Krzysztof K. , Basińska Małgorzata , Błachnio Aleksandra
Published: June 2023

Background

Human health is determined by a number of physical, social and psychological factors, including the often considered health behaviors. They are an indispensable part of the health recovery process and are also the basis of prevention in the development of such disorders as atherosclerosis. Health behaviors are reinforced by an individual’s resources such as posi-tive orientation, which is composed of optimism, high self-esteem and satisfaction with life. The main objective of the study was to determine whether there is a relationship between positive orientation and health behavior, in a group of peo-ple with atherosclerosis.

Participants and procedure

Sixty-one patients, both male and female, in late adulthood were surveyed (M = 69.41, SD = 5.44). A researcher-designed questionnaire, the Health Behavior Inventory (IZZ) and the Positive Orientation Scale (P-Scale) were used in the measure-ment. The study was conducted in accordance with the ethical principles of the 2013 Declaration of Helsinki.

Results

The results showed that patients with a more positive attitude toward life are more likely to use health-promoting behav-iors.

Conclusions

There is a positive relationship between positive orientation and health behaviors. Positive orientation can be enhanced through appropriate psychoeducation and psychological support to prevent ill health and improve treatment of patients with atherosclerosis.

Published: June 2023

An experiment to study the behavior of a humic acid preparation isolated from arable gray soil (Luvic Greyzemic Phaeozem (Loamic, Aric)) in solution has been set. The aim of the work is to assess environmental changes in the presence of humic acid solution. In the work, the content of dissolved oxygen in the incubation vessels is recorded, data on the optical density and fluorescence spectra of the suspensions studied are obtained, and the parameters of the state of the alga Chlorella vulgaris culture, such as the size and number of cells, are evaluated. It is noted that in the presence of humic acid solution, the growth character of the algae culture changes. A significant drop in the content of dissolved oxygen in the experiment with humic acid solution on day 5 was found, which is most pronounced in the light, resulting in better conditions for the green algae.

Published: June 2023

Aim: This study aimed to describe the behavior, eating habits, and lifestyle of schoolchildren from different regions of Bejaia, and to evaluate their food consumption on the one hand and their Physical Activity Level (PAL) on the other hand. Methods: This study involved children (n = 240, B/G = 120/120), aged from 6 to 12, that are enrolled in different institutions (primary schools, colleges) in different regions of Bejaia. The children's body weight and height were measured (BMI), and their eating habits and level of physical activity were assessed using adapted questionnaires. Food consumption was estimated by the 24-hour recall method. Results: Results showed observable BMI rise including drastic changes in BMI Z-score as a function of age, height and mainly weight, BMI Z-score values were between 0 and +2 in overweight for obese girls and boys and less than +1 for normal-weight girls and boys. The PAL evaluation was low in overweight and obese children compared to normal-weight children. The correlation test showed a positive correlation between BMI and PAL in both sexes. According to the results of the dietary habits, the frequency of consumption of the different food groups distributed according to the fourth daily intakes (breakfast, lunch, dinner and snacking between meals) was very rich in carbohydrates and fats in overweight and obese children, compared to normal-weight children and according to the recommended threshold. Conclusion: This study shows that there is an increase in BMI values, high BMI Z-scores in overweight and obese children compared to normal-weight children. Children have bad eating habits (snacking between meals, consumption of fast food and sugary drinks). These habits may act as obesity promoting factors when associated with sedentary activities.

Published: June 2023

Abstract. To assess their potential for beef production, this study describes the morphometrics, physical traits, and body weight of 1034 Indonesian beef cattle from eight breeds, namely Bali, Rambon, Madura, Ongole Grade, Kebumen Ongole Grade, Sasra, Jabres, and Pasundan. An analysis of variance in addition to cluster, Euclidean distance, dendrogram, discriminant
function, stepwise linear regression, and morphological index analyses were
performed to describe the differences in traits among breeds. The morphometric proximity analysis revealed two distinct clusters with a common ancestor, where the first cluster included Jabres, Pasundan, Rambon, Bali, and Madura cattle and the second included Ongole Grade, Kebumen Ongole Grade, and Sasra cattle, with an average suitability value of 93.20 %. This showed that the classification and validation methods can be used to distinguish breeds. The most important factor in estimating body weight was the heart girth circumference. Ongole Grade cattle had the highest cumulative index, followed by Sasra, Kebumen Ongole Grade, Rambon, and Bali cattle. A cumulative index value >3 can be used as a threshold
for determining the type and function of beef cattle.
Spatial regression of multi-fidelity meteorological observations using a proxy-based measurement error model
Authors: de Baar Jouke H. S. , Garcia-Marti Irene , van der Schrier Gerard
Published: June 2023

Abstract. High-resolution weather maps are fundamental components of early warning systems, since they enable the (near) real-time tracking of extreme weather events. In this context, crowd-sourced weather networks producing low-fidelity observations are often the only type of data available at local (e.g. neighborhood) scales. In this work, we demonstrate that we can provide such maps by combining high-fidelity official weather data with low-fidelity crowd-sourced weather data and high-resolution covariate information. Because the crowd-sourced data contains significant bias and noise, we develop an approach to include a bias budget and noise budget in the multi-fidelity Bayesian spatial data analysis. The weights of the different components of these bias and noise budgets are tuned to the data set. We apply this approach to 24 hours of weather data in the Netherlands, for a day that had a “code orange” (i.e. “be prepared for extreme weather with high risk of impact”) weather warning for heavy precipitation. From our analysis, we see a significant – qualitative and quantitative – synergy effect when introducing low-fidelity data and high-resolution covariate information.

Published: June 2023

Abstract. Until now, the processes involved in secondary ice production which generate high concentrations of ice crystals in clouds have been poorly understood. However, collisions that involve rimed ice particles or crystal aggregates have the potential to effectively produce secondary ice from their fragmentation. Unfortunately, there have only been a few laboratory studies on ice-ice collision, resulting in an inaccurate representation of this process in microphysical schemes. To address this issue, experiments were conducted at the Wind tunnel laboratory of the Johannes Gutenberg University, Mainz on graupel- graupel and graupel-snowflake collisions under still air conditions at -15 °C and over water saturation. All fragments resulting from graupel-graupel collisions were collected and investigated by means of a digital optical microscope, while fragments from graupel-snowflake collisions were observed and recorded instantly after collision using a holographic instrument. From these experiments, distributions were obtained for fragment sizes, cross sectional areas and aspect ratios. The results showed a higher number of fragments at lower kinetic energy compared to those presented in the literature. 150 to 600 fragments were observed for graupel-graupel collisions, and 70 to 500 fragments for graupel-snowflake collisions between 10−7 and 10−5 J. Parametrizations for fragment size distributions are provided with a mode at 75 µm for graupel-graupel collisions and at 400 µm for graupel-snowflake collisions. These results can be used to improve the representation of ice collision breakup in microphysical schemes.

Abstract. Nucleophilic high-molecular-weight organic compounds (HMWOC) are sensitive to proton (H+) in FT-ICR MS analysis. A comprehensive evaluation of diurnal evolution of nucleophilic HMWOC was performed. HMWOCs aged significantly in daily cycles, accompanied by functionality shifts, particularly oxygenated and reduced nitrogen (CHON and CHN) and oxygenated organics. The intensities of HMW oxygenated compounds increased during daytime and nighttime. The daytime evolution produced more nitrogen-containing compounds with carboxylic groups (–COOH) homologs with molecular weights greater than 300, while the nighttime evolution produced mostly small CHON compounds (molecular weights <300). During evolution, nighttime CHON removals were also observed; meanwhile, carboxylation was also identified in CHON groups. The daytime evolution produced significantly more reduced nitrogen-containing compounds and a day- and nighttime increase in CHN compounds with five members was also observed. This study can provide insights into the aging of less polar organic aerosols.

Abstract. Land cover and land management change (LCLMC) has been highlighted for its critical role in mitigation scenarios, both in terms of global mitigation and local adaptation. Yet, the climate effect of individual LCLMC options, their dependence on the background climate and the local vs. non-local responses are still poorly understood across different Earth system models (ESMs). Here we simulate the climatic effects of LCLMC using three state-of-the-art ESMs, including the Community Earth System Model (CESM), the Max Planck Institute for Meteorology Earth System Model (MPI-ESM) and the European Consortium Earth System Model (EC-EARTH). We assess the LCLMC effects using the following four idealized experiments: (i) a fully afforested world, (ii) a world fully covered by cropland, (ii) a fully afforested world with extensive wood harvesting and (iv) a full-cropland world with extensive irrigation. In these idealized sensitivity experiments, performed under present-day climate conditions, the effects of the different LCLMC strategies represent an upper bound for the potential of global mitigation and local adaptation. To disentangle the local and non-local effects from the LCLMC, a checkerboard-like LCLMC perturbation, i.e. alternating grid boxes with and without LCLMC, is applied. The local effects of deforestation on surface temperature are largely consistent across the ESMs and the observations, with a cooling in boreal latitudes and a warming in the tropics. However, the energy balance components driving the change in surface temperature show less consistency across the ESMs and the observations. Additionally, some biases exist in specific ESMs, such as a strong albedo response in CESM mid-latitudes and a soil-thawing-driven warming in boreal latitudes in EC-EARTH. The non-local effects on surface temperature are broadly consistent across ESMs for afforestation, though larger model uncertainty exists for cropland expansion. Irrigation clearly induces a cooling effect; however, the ESMs disagree whether these are mainly local or non-local effects. Wood harvesting is found to have no discernible biogeophysical effects on climate. Overall, our results underline the potential of ensemble simulations to inform decision making regarding future climate consequences of land-based mitigation and adaptation strategies.

Abstract. China is facing the challenge of synergistic reduction of
air pollutants and CO2 emissions. However, the studies on its
historical progress and future priorities are insufficient. This study
compiled China's emission inventory of air pollutants and CO2 from 2005
to 2021 (ABaCAS-EI v2.0 dataset) based on a unified emission-source
framework by considering the influences of activity level, technology
evolution, and emission control policies. The characteristics of air
pollutants and CO2 emissions were comprehensively analyzed from
multiple dimensions such as time, space, sector, and synergies between air
pollutants and CO2 emissions. Mitigation policies have decoupled the
emissions of air pollutants and CO2 with economic development in China
since 2013. In the context of growing activity levels, energy structure
adjustment and energy and material saving reduced the average annual
increase rate of CO2 emissions by 7 % after 2011. Based on this,
end-of-pipe control contributed 51 %–98 % of air pollutant emission
reductions after 2013. Industrial boilers and residential fossil fuel
combustion sectors in seven provinces (Beijing, Tianjin, Shanghai, Jilin,
Henan, Sichuan, and Qinghai) achieved emission reductions in both air
pollutants and CO2 during 2013–2021. The declining trends in both the
sectoral and regional emission ratios of air pollutants to CO2
indicated that the potential for synergistic emission reduction in China
declined from 2013 to 2021. The emission ratios in 2021 showed that
residential fossil fuel combustion, iron and steel industry, and
transportation exhibited relatively higher co-benefits of SO2,
PM2.5, NOx, and VOC emission reductions when CO2 emissions were
reduced. Most cities with a higher potential to synergistically reduce NOx,
VOC, and CO2 emissions were within the Yangtze River Economic Belt,
while those with a higher potential to co-control SO2 and CO2, and
PM2.5 and CO2 were in southern and northeast China, respectively.
Further deconstruction of the sectoral emissions in 2021 suggested future
reduction measures: for example, controlling coal consumption in the energy
field; promoting innovative technologies with low air pollutant emission
intensities and coal-saving measures in the iron and steel industry;
combining coal and carbonate replacement technologies with separated
particle control measures in the cement industry; and controlling light-duty
passenger vehicles, heavy-duty trucks, agricultural machinery, and inland
water transport in the transportation sector. Our dataset and findings
provide insights into the co-control of air pollutants and CO2
emissions in the future in China and other countries with the same demand.

Abstract. Here we present the high-resolution CFA data from the top 479 m of the East Greenland Ice coring Project (EGRIP) ice core covering the past 3.8 thousand years. The data consists of 1 mm-depth-resolution profiles of calcium, sodium, am- monium, nitrate and electrolytic conductivity as well as decadal averages of these profiles. Alongside the data we provide a description of the measurement setup, procedures, the relevant references for the specific methods as well as an assessment of the precision of the measurements, the sample to depth assignment and the depth and temporal resolution of the data set. The nominally 1-mm data represents an oversampling of the record as the true resolution is limited by the analytical setup to approximately 1 cm. The error of absolute depth assignment of the data may be on the order of 1 cm, however relative depth offsets be- tween the records of the individual species is only on the order of 1 mm. The presented data has sub-annual resolution over the entire depth range and has already formed part of the data for an annually layer-counted time scale for the EGRIP ice core used to improve and revise the multi-core Greenland ice-core chronology (GICC05) to a new version,GICC21 (Sinnl et al., 2021). The data is available in full 1-mm resolution and decadal averages on PANGAEA (https://doi.org/10.1594/PANGAEA.945293 (Erhardt et al., 2022b))
XLUM: an open data format for exchange and long-term preservation of luminescence data

Published: June 2023

Abstract. The concept of open data has become the modern science meme, and major funding bodies and publishers support open data. On a daily basis, however, the
open data mandate frequently encounters technical obstacles, such as a lack of a suitable data format for data sharing and long-term data
preservation. Such issues are often community-specific and best addressed through community-tailored solutions. In Quaternary sciences, luminescence
dating is widely used for constraining the timing of event-based processes (e.g. sediment transport). Every luminescence dating study produces a
vast body of primary data that usually remains inaccessible and incompatible with future studies or adjacent scientific disciplines. To facilitate
data exchange and long-term data preservation (in short, open data) in luminescence dating studies, we propose a new XML-based structured data
format called XLUM. The format applies a hierarchical data storage concept consisting of a root node (node 0), a sample (node 1), a sequence
(node 2), a record (node 3), and a curve (node 4). The curve level holds information on the technical component (e.g. photomultiplier,
thermocouple). A finite number of curves represent a record (e.g. an optically stimulated luminescence curve). Records are part of a sequence
measured for a particular sample. This design concept allows the user to retain information on a technical component level from the measurement
process. The additional storage of related metadata fosters future data mining projects on large datasets. The XML-based format is less
memory-efficient than binary formats; however, its focus is data exchange, preservation, and hence XLUM long-term format stability by
design. XLUM is inherently stable to future updates and backwards-compatible. We support XLUM through a new R package xlum,
facilitating the conversion of different formats into the new XLUM format. XLUM is licensed under the MIT licence and hence available
for free to be used in open- and closed-source commercial and non-commercial software and research projects.
The statistical emulators of GGCMI phase 2: responses of year-to-year variation of crop yield to CO2, temperature, water and nitrogen perturbations

Published: June 2023

Abstract. Understanding the impact of climate change on year-to-year variation of crop yield is critical to global food stability and security. While crop model emulators are believed to be lightweight tools to replaces the models per se, few emulators have been developed to capture such interannual variation of crop yield in response to climate variability. In this study, we developed a statistical emulator with machine learning algorithm to reproduce the response of year-to-year variation of four crop yield to CO2 (C), temperature (T), water (W) and nitrogen (N) perturbations defined in the Global Gridded Crop Model Intercomparison Project (GGCMI) phase 2 experiment. The emulators were able to explain more than 92 % variance of simulated yield and performed well in capturing the year-to-year variation of global average and gridded crop yield over current croplands in the baseline. With the changes in CTWN perturbations, the emulators could well reproduce the year-to-year variation of crop yield over most current cropland. The variation of R and the mean absolute error was small under the single CTWN perturbations and dual factor perturbations. These emulators thus provide statistical response surfaces of yield, including both its mean and interannual variability, to climate factors. They could facilitate spatiotemporal downscaling of crop model simulation, projecting the changes in crop yield variability in the future, and serving as a lightweight tool of multi-model ensemble simulation. The emulators enhanced the flexibility of crop yield estimates and expanded the application of large-ensemble simulation of crop yield under climate change.

Abstract. In the research work presented here, an integrating sphere demonstrator which is suitable for the non-destructive determination of the degree of cross-linking or curing and has the potential for use as an at-line device for in-process quality assurance was assembled and explored. The measurement system allows the analysis of absorption and scattering coefficients of materials independently by means of absolute optical spectroscopy. The two optical parameters showed a good correlation with the degree of cross-linking of cross-linked polyethylene (PE-X) and the degree of curing of different thermosets and adhesives, each of which was determined using different reference methods (wet chemical analysis, differential scanning calorimetry (DSC), and dielectric analysis (DEA)). The results show that different PE-X materials can be distinguished well by their absorption and scattering in the visual (VIS) and near-infrared (NIR) wavelength range, respectively, and conclusions on their degree of cross-linking are possible. Also, the curing of resins can be monitored based on the absorption. In addition, Raman spectroscopy was used to achieve a better understanding of the material changes during the cross-linking of the materials. It also showed a good suitability for monitoring the curing processes in thermosets. In summary, the new method can be used to determine the crucial parameters of these industrial important material types and fulfils the great demand for fast, non-destructive testing, which can be carried out during the process or on the finished product.
A methodological framework for the evaluation of short-range flash-flood hydrometeorological forecasts at the event scale

Published: June 2023

Abstract. This paper presents a methodological framework designed for the event-based evaluation of short-range hydrometeorological ensemble forecasts, in the specific context of an intense flash-flood event characterized by high spatiotemporal variability. The proposed evaluation adopts the point of view of end users in charge of the organization of evacuations and rescue operations at a regional scale. Therefore, the local exceedance of discharge thresholds should be anticipated in time and accurately localized. A step-by-step approach is proposed, including first an evaluation of the rainfall forecasts. This first step helps us to define appropriate spatial and temporal scales for the evaluation of flood forecasts. The anticipation of the flood rising limb (discharge thresholds) is then analyzed at a large number of ungauged sub-catchments using simulated flows and zero-future rainfall forecasts as references. Based on this second step, several gauged sub-catchments are selected, at which a detailed evaluation of the forecast hydrographs is finally achieved. This methodology is tested and illustrated for the October 2018 flash flood which affected part of the Aude River basin (southeastern France). Three ensemble rainfall nowcasting research products recently proposed by Météo-France are evaluated and compared. The results show that, provided that the larger ensemble percentiles are considered (75th percentile for instance), these products correctly retrieve the area where the larger rainfall accumulations were observed but have a tendency to overestimate its spatial extent. The hydrological evaluation indicates that the discharge threshold exceedances are better localized and anticipated if compared to a naive zero-future rainfall scenario but at the price of a significant increase in false alarms. Some differences in the performances between the three ensemble rainfall forecast products are also identified. Finally, even if the evaluation of ensemble hydrometeorological forecasts based on a low number of documented flood events remains challenging due to the limited statistical representation of the available data, the evaluation framework proposed herein should contribute to draw first conclusions about the usefulness of newly developed rainfall forecast ensembles for flash-flood forecasting purpose and about their limits and possible improvements.

Stock is one of the most popular instruments traded in the capital market. Issuing shares is one of the choices made by companies when deciding to fund the company. In addition, stocks are an investment alternative that has been chosen by many investors because stocks are able to provide attractive returns. The movement of stock prices is a stochastic process, where today's price is affected by the previous day's stock price, and tomorrow's stock price is influenced by today's stock price. Thus, the movement of this stock price is a markov chain where the movement can occur repeatedly, but the exact time cannot be known. By studying the long-term behavior of the Markov chain, it is possible to predict stock movements in the future

La importancia de la forma en el cine de Ruy Duarte de Carvalho
Authors: González-García Fernando
Published: June 2023

El cine del escritor y antropólogo Ruy Duarte de Carvalho ha sido estudiado desde la perspectiva de la antropología y desde la contextualización histórica de su función política en la Angola de los años setenta y ochenta. En este trabajo quiero, complementariamente, examinar su puesta en forma. Las películas de Duarte son obras de urgencia, pero también son obras de un poeta para el que la forma fílmica es importante: más allá de facilitar su circulación, contribuye a que las películas cumplan una función que supere el mero encargo propagandístico. Las obras cinematográficas de Duarte de Carvalho parten de los postulados del MPLA, pero los problematizan, prestando atención y dando voz a etnias cuya relación con lo real no se adecua al tiempo lineal y a la idea de progreso. Al mismo tiempo, sus estrategias constructivas les permiten alzar el vuelo y acercarse cada vez más a lo que Duarte llamó en alguna ocasión poesía no escrita.

The impact of Covid 19 on dentistry has been profound with dental clinicians, who are at high risk of exposure to the virus. Initially at the inception of the pandemic, during the periods of lockdown, the elective dental treatment was halted and advice, analgesia and antimicrobials were preferred to manage the dental emergencies. Some patients could not be successfully managed with this approach and required face-to-face consultation. Therefore, dental emergency assessment via telephonic triage, Covid 19 screening and strict adherence to standard operating protocols for the patient, operatory and dentist were ensured while providing dental treatment based on minimum intervention and restraining from aerosol generating procedures. Now three years from the commencement of the pandemic, calls have been made for gradual return to regular clinical practice with extra precautions. Due to the emergence of new variants and ongoing easing and reimplementation of restrictions, it remains imperative to mitigate the risk of disease transmission during the dental treatment. Thus, this article provides an insight into the clinical protocols for the management of endodontic emergencies in the Covid 19 era, making the dentist better prepared to provide dental care in the patient’s best interest during such pandemic disease outbreaks now and in future.
