Strategy optimization method based on UAVs‐assisted detection of covert communication
Authors: Wang Xiaohan , Tian Wen , Liu Guangjie , Dai Yuwei 
Published: February 2025

AbstractUnmanned aerial vehicles (UAVs) are highly mobile and easily deployable devices that have become an important component of wireless communication countermeasures. Covert communication, the main method used to ensure wireless communication security, has been extensively studied in recent years. However, existing research primarily uses UAVs as auxiliary tools for covert communications, to improve communication performance, ignoring situations in which the detector utilizes UAVs for interference suppression. In this study, we propose a UAV‐assisted jamming detection covert communication game model. Specifically, the UAV actively transmits noise to Alice's transmission channels to disrupt covert transmission when Willie detects a covert communication transmission. Furthermore, we analyze the adversarial process between the detector and Alice under UAV‐assisted jamming based on game theory, theoretically verify the conditions for the existence of a Nash equilibrium, and formulate optimal strategies for both sides.
Movement of the South Russian Frontier in the 17th – First Half of the 19th Centuries as the Development of the “Wild Fields”
Authors: Kanishchev Valery V. , Mizis Yuri A. 
Published: February 2025

The authors of the article made an attempt to clarify the concept of frontier, considering it not only in a civilizational sense, but also in a socio-natural context. Particular attention was paid to the movement of the frontier as the development of the “Dykoee Polee” [Rus: steppe, “Wild Fields”], a space not yet plowed by farmers. The purpose of the article was to measure the concrete degree of evolution of the zone of the South Russian frontier during the 17th – 19th centuries in terms of the scale of settlement, population density, and plowing of land. As a result of the study, specific indicators of the development of the “Wild Fields” were obtained: widespread settlement in riverine and upland areas, population density equal to the old regions in the Center of Russia, plowing of more than half of the territory of the former frontier zone, in some “uezds” [Rus.: a group of districts gravitating towards the city] even more than in the traditionally arable central “uezds”. In conclusion, the authors drew attention to the usefulness of studying the nonlinear effects in the development of the “Wild Fields”. In particular, it concerns the economic development of apicultural and other areas, hundreds of which at the end of the 16th – 17th centuries were located in the part of the “Wild Fields” that had not yet been subordinated to the Russian state, as well as the traces of agricultural hike on the territories south of the frontier of the 17th century developed there long before the construction of fortresses and defensive ramparts, – the facts identified recently in collaboration with soil scientists.

Authors: Arochman Taufik , Arifin M Fatkhu 
Published: February 2025

Dari hasil observasi didapati bahwa di SMK Muhammadiyah Bandongan masih belum ada gerakan atau aktivitas jurnalistik yang mapan. Hal ini ditakutkan akan menyebabkan komunikasi publik di lingkungan sekolah tidak produktif dan malah destruktif. Oleh sebab itu, tim pengusul meyakini perlu adanya upaya meningkatkan pemahaman dan keterampilan jurnalistik guna menumbuhkan pola komunikasi publik yang produktif dan sehat. Kegiatan pengabdian ini bertujuan untuk memberi pemahaman tentang jurnalistik dasar yang diharapkan dapat dijadikan bekal dalam menerima berita dan/atau informasi dari media massa. Selain itu, pengabdian ini dimaksudkan untuk membekali target sasaran kegaitan keterampilan jurnalistik dasar dalam rangka membangun aktivitas jurnalistik yang sehat di lingkunagan sekolah. Ruang jurnalisme yang sehat diharapkan akan menjadi sarana bagi seluruh komponen sekolah, terutama siswa, dalam menyampaikan aspirasi. Kesimpulan yang dapat ditarik dari kegiatan ini adalah bahwa penting mengenalkan dunia jurnalistik sejak dini, terutama pada pelajar SMK/Sederajat yang notabene sudah mendekati usia dewasa. Pentingnya pemahaman jurnalistik bagi pelajar dapat membangun generasi yang tidak latah dengan pemberitaan di media. Beranjak dari kesimpulan yang didapat, yang menjadi rekomendasi utama ialah perlunya membangun budaya jurnalistik di lingkungan sekolah. Jurnalisme sekolah, selain sebagai penyedia informasi, dapat juga menjadi media bagi siswa untuk menyampaikan aspirasinya.

Authors: Dewi Nofita  , Budi Setiawan  
Published: February 2025

Lemon is a fruit rich in vitamin C. Processing lemon as lemon infused water is one way to get the optimal benefits from lemon. Lemon infused water is processed by soaking it in water for several hours. Temperature and storage time are thought to affect the vitamin C levels of lemon. This study aims to determine the effect of temperature and storage time on the vitamin C levels of lemon infused water. This study used the lodimetry method with temperatures of 5°C, 10°C, 28℃C and storage times of 1,3,5 hours. Furthermore, the vitamin C levels of lemon infused water were analyzed. The results showed that temperature and storage time affected the vitamin C levels of lemon infused water (Citrus Limon). The higher the storage temperature of lemon infused water, the higher the vitamin C levels. The lower the storage temperature of lemon infused water, the lower the vitamin CC levels. The longer the storage, the lower the vitamin C levels of lemon infused water. Storage for 1 hour at a temperature of 28°C is the best time to obtain vitamin C levels. From the study, the vitamin C content of lemon infused water was 0.158% b/b.

Authors: Yılmaz Ahmet Münir , Kalıntaş Enes , Yılmaz Hatice Eylem Kömürcüler 
Published: February 2025

BACKGROUND:
Traffic accidents are one of the most important reasons that increase the workload of emergency services all over the world. Especially in developing countries, this problem is difficult to solve due to rapid population growth.

OBJECTIVE:
The aim of this study was to evaluate the causes of mortality and morbidity, the organs affected by the injury, and the prognosis of the patients who are referred to the emergency department as a result of traffic accidents and underwent abdominal imaging.

DESIGN:
Retrospective, cross-sectional study

SETTING:
A state hospital in Turkey

PATIENTS AND METHODS:
1014 patients admitted to Gaziantep Abdulkadir Yüksel State Hospital between 15 July 2022 to 15 July 2023 due to traffic accidents and examined for abdominal trauma were retrospectively evaluated.

MAIN OUTCOME MEASURES:
Evaluation of patients admitted due to traffic accidents and examined for abdominal trauma.

SAMPLE SIZE:
1014 patients

RESULTS:
The mean age of the patients was 25.88 years, 79.6% were male, 67.3% were admitted to the hospital by ambulance, 47.4% were admitted as a result of a vehicular traffic accident, 34.3% were admitted as a result of a non-vehicular traffic accident, 18.2% were admitted as a result of a motorcycle accident and 36.4% were drivers, 35.3% were pedestrians and 28.3% were passengers. Intra-abdominal organ injuries were detected in 3.2% of all patients, including urinary system in 1%, hepatobiliary system in 0.9% and spleen in 0.8%. It was determined that 13% of the patients had life-threatening injuries and 40.2% had injuries that could not be treated with simple medical intervention.

CONCLUSION:
It was determined that 21% of the patients admitted to the emergency department as a result of traffic accidents required hospitalization or resulted in death. Prevention of traffic accidents, which especially threaten the young population, is of great importance both in reducing the workload in the emergency department and in minimizing labor and financial losses.

LIMITATIONS:
Since the study was based on retrospective file review, files with missing information were not included in the study.

Authors: Türk Merve Ayık , Kömürcüoğlu Berna , Agüloğlu Nurşin , Çiftçi Tuğçe Doksöz , Fidan Mücahit , Çolak Sinan , Batum Özgür 
Published: February 2025

BACKGROUND:
Small cell lung cancer (SCLC) is a lung malignancy with a poor prognosis and metastases at the time of diagnosis. There is limited experience using positron emission tomography/computed tomography (PET/CT) for SCLC diagnosis, staging, and follow-up.

OBJECTIVE:
Investigate the survival effect of primary tumor standardized uptake value max (SUVmax), SUV mean, metabolic tumor volume (MTV), total lesion glucose (TLG), bone marrow SUV (BM), and bone marrow to liver ratio (BLR) in SCLC.

DESIGN:
Retrospective

SETTING:
Single center in Turkey

PATIENTS AND METHODS:
Patients who were cyto/histologically diagnosed with SCLC and had PET/CT simultaneous with the diagnosis were included in the study.

MAIN OUTCOME MEASURES:
The effect of PET/CT parameters on overall survival (OS) and progression-free survival (PFS).

SAMPLE SIZE:
304

RESULTS:

The 5-year OS median value was 14.62 months, and the 5-year PFS was 13.01 months. In Kaplan-Meier analysis, SUVmax, MTV, and TLG were statistically significant variables in OS (
P
=.03;
P
<.001;
P
<.001, respectively). MTV and TLG were significant in PFS (
P
<.001;
P
=.0003, respectively). In the multivariate analysis, MTV was an independent PET/CT parameter associated with OS (
P
=.003), stage of disease (
P
=.012), SUVmax (
P
=.003), MTV (
P
=.016), and TLG (
P
=.005) were significant variables in PFS.

CONCLUSION:
In our study, MTV was an independent parameter that can be used to predict survival in SCLC. Considering the effect of MTV, a metabolic PET/CT parameter on survival, it can be recommended for clinical use as a standard measure of evaluation in PET/CT reports, just like SUVmax.

LIMITATIONS:
The first limitation was the single-center and retrospective design of the study. Due to the retrospective design of the study, weight loss, performance status, and smoking history could not be obtained from every patient. Second, inaccurate registration of PET and CT images due to patient respiratory movements may affect measurements.
Moving beyond post hoc explainable artificial intelligence: a perspective paper on lessons learned from dynamical climate modeling
Authors: O'Loughlin Ryan J. , Li Dan , Neale Richard , O'Brien Travis A. 
Published: February 2025

Abstract. AI models are criticized as being black boxes, potentially subjecting climate science to greater uncertainty. Explainable artificial intelligence (XAI) has been proposed to probe AI models and increase trust. In this review and perspective paper, we suggest that, in addition to using XAI methods, AI researchers in climate science can learn from past successes in the development of physics-based dynamical climate models. Dynamical models are complex but have gained trust because their successes and failures can sometimes be attributed to specific components or sub-models, such as when model bias is explained by pointing to a particular parameterization. We propose three types of understanding as a basis to evaluate trust in dynamical and AI models alike: (1) instrumental understanding, which is obtained when a model has passed a functional test; (2) statistical understanding, obtained when researchers can make sense of the modeling results using statistical techniques to identify input–output relationships; and (3) component-level understanding, which refers to modelers' ability to point to specific model components or parts in the model architecture as the culprit for erratic model behaviors or as the crucial reason why the model functions well. We demonstrate how component-level understanding has been sought and achieved via climate model intercomparison projects over the past several decades. Such component-level understanding routinely leads to model improvements and may also serve as a template for thinking about AI-driven climate science. Currently, XAI methods can help explain the behaviors of AI models by focusing on the mapping between input and output, thereby increasing the statistical understanding of AI models. Yet, to further increase our understanding of AI models, we will have to build AI models that have interpretable components amenable to component-level understanding. We give recent examples from the AI climate science literature to highlight some recent, albeit limited, successes in achieving component-level understanding and thereby explaining model behavior. The merit of such interpretable AI models is that they serve as a stronger basis for trust in climate modeling and, by extension, downstream uses of climate model data.
Insights into the tectonic evolution of the Svecofennian orogeny based on in situ Lu–Hf dating of garnet and apatite from Olkiluoto, southwestern Finland

Published: February 2025

Abstract. The southern Finland granites and associated migmatitic rocks have a complex metamorphic history, being affected by multiple events during the ca. 1.88–1.79 Ga Svecofennian orogeny. In this study, the prolonged tectonic evolution of migmatites and associated rocks in southwestern Finland has been investigated using the new in situ Lu–Hf method. Results reveal detailed temporal constraints for the tectonic evolution that can be linked to major events in adjacent tectonic blocks in both Finland and Sweden during the Svecofennian orogeny. The metamorphic peak at the Olkiluoto site occurred at 1829 ± 19 Ma based on in situ Lu–Hf dating of garnet. The pressure–temperature (P–T) path for the rocks indicates a prograde evolution, with peak P–T conditions of 3–5 kbar and approximately 700 °C. Younger ages of ca. 1780 Ma obtained using both Lu–Hf and U–Pb systems in apatite inclusions in garnet indicate rapid cooling at 1780 Ma. Based on the metamorphic constraints and obtained ages, we link the Olkiluoto site to the Häme orogenic belt in southern Finland and also support the proposed thermal–tectonic connection with the Ljusdal lithotectonic unit in central Sweden.

Published: February 2025

The COVID-19 epidemic, which began to spread globally in early 2020, created an abrupt change that has brought with it unimaginable challenges and profound adjustments to many elements and areas of human existence. This research delves into how the COVID-19 pandemic transformed travel patterns in Lahore, Pakistan. It analyzes the surveys conducted to understand people's travel behaviors before, during, and after the pandemic's peak. The survey consists of total 38 questions concerning about the travel pattern of participants in pre-pandemic, during pandemic and post-pandemic along with socioeconomic factors. Factor analysis has been used to analyse the collected data. For factor analysis seven latent variable have been determined. The results show a significant change in travel pattern of individuals. During the pandemic, public transportation utilization fell drastically, and this decline persisted long after restrictions were lifted. In the same manner, there was a decline in the use of carpooling and taxis, following a subsequent partial recovery. In addition, the pandemic appears to have pushed people towards habit of online shopping and some people and offices towards remote working. This shift towards virtual alternatives may have long-term effects as individuals get used to of these new schedules. Furthermore, there have been a decline in social visits such as family, friends and social works including expos, volunteer and community works. Essentially, the research highlights the COVID-19 pandemic as a watershed moment for travel patterns in Lahore. It triggered a rise in personal car use, a surge in remote work and online shopping, and a temporary decline in social visits by car. The research indicates that certain modifications, including the adoption of remote work and virtual communication, could eventually become standard practices, impacting urban living and working patterns.
