Adversarial Robustness for Deep Learning-based Wildfire Prediction Models
Authors: Ide Ryo , Yang Lei
Published: January 2025

Smoke detection using Deep Neural Networks (DNNs) is an effective approach for early wildfire detection. However, because smoke is temporally and spatially anomalous, there are limitations in collecting sufficient training data. This raises overfitting and bias concerns in existing DNN-based wildfire detection models. Thus, we introduce WARP (Wildfire Adversarial Robustness Procedure), the first model-agnostic framework for evaluating the adversarial robustness of DNN-based wildfire detection models. WARP addresses limitations in smoke image diversity using global and local adversarial attack methods. The global attack method uses image-contextualized Gaussian noise, while the local attack method uses patch noise injection, tailored to address critical aspects of wildfire detection. Leveraging WARP’s model-agnostic capabilities, we assess the adversarial robustness of real-time Convolutional Neural Networks (CNNs) and Transformers. The analysis revealed valuable insights into the models’ limitations. Specifically, the global attack method demonstrates that the Transformer model has more than 70% precision degradation than the CNN against global noise. In contrast, the local attack method shows that both models are susceptible to cloud image injections when detecting smoke-positive instances, suggesting a need for model improvements through data augmentation. WARP’s comprehensive robustness analysis contributed to the development of wildfire-specific data augmentation strategies, marking a step toward practicality.

N-containing carbon-based materials have been employed with claimed improved performance as adsorbent of acidic molecules, VOC and metallic ions, catalyst, electrocatalyst and supercapacitor. In this context, the present work provides valuable insights into the preparation of N-doped activated carbons (ACs) by thermal treatment in NH3 atmosphere (ammonization). A commercial AC was submitted to two kinds of pre-treatment: (i) reflux with dilute HNO3; (ii) thermal treatment up to 800 oC in inert atmosphere. The original and modified ACs were subjected to ammonization up to different temperatures. ACs with N content up to 8% were achieved. Nevertheless, the amount and type of inserted nitrogen depended on ammonization temperature and surface composition of the starting material. Remarkably, oxygenated acidic groups on the surface of the starting material favored nitrogen insertion at low temperatures, with formation of mostly aliphatic (amines, imides, and lactams), pyridinic and pyrrolic nitrogens. In turn, high temperatures provoked the decomposition of labile aliphatic functions. Therefore, the AC prepared from the sample pre-treated with HNO3, which had the highest content of oxygenated acidic groups among the materials submitted to ammonization, presented the highest N content after ammonization up to 400 oC, but the lowest content after ammonization up to 800 oC.

Gastric cancer (GC) ranks as the fifth most prevalent malignant neoplasm globally, with an increased death rate despite recent advancements in research and therapeutic options. Different molecular subtypes of GC have distinct interactions with the immune system, impacting the tumor microenvironment (TME), prognosis, and reaction to immunotherapy. Tumor-infiltrating lymphocytes (TILs) in the TME are crucial for preventing tumor growth and metastasis, as evidenced by research showing that patients with GC who have a significant density of TILs have better survival rates. But cancer cells have evolved a variety of mechanisms to evade immune surveillance, both sialic acid-binding immunoglobulin-like lectin 15 (Siglec-15) and Programmed Death-Ligand 1 (PD-L1) playing a pivotal role in the development of an immunosuppressive TME. They prevent T cell activation and proliferation resulting in a decrease in the immune system’s capacity to recognize and eliminate malignant cells. These immune checkpoint molecules function via different but complementary mechanisms, the expression of Siglec-15 being mutually exclusive with PD-L1 and, therefore, providing a different therapeutic approach. The review explores how TILs affect tumor growth and patient outcomes in GC, with particular emphasis on their interactions within the TME and potential targeting of the PD-L1 and Siglec-15 pathways for immunotherapy.
Beyond Correlation to Causation in Hunter-Gatherer Ritual Landscapes: Testing an Ontological Model of Site Locations in the Mojave Desert, California
Authors: Whitley David S , Lancaster JD , Catacora Andrea
Published: January 2025

Why are rock art sites found in certain places and not others? Can locational or environmental variables inform an understanding of the function and meaning of the art? How can we move beyond observed patterning in spatial associations to a credible explanation of such meanings and ensure that we are not confusing correlation with causation? And what variables were most relevant in influencing site locational choices? These and related problems, whether recognized or not, are the subtext of the last three decades of rock art site distributional and landscape studies. They are now especially important to resolve given the need for accurate predictive modeling due to the rapid transformation of certain regions from undeveloped rural areas into rural industrial landscapes. Partly with this problem in mind, Whitley (2024) developed a descriptive model that provides an explanation for the location of Native Californian rock art in the Mojave Desert. It identifies the variables most relevant to site locations based on ethnographic Indigenous ontological beliefs about the landscape. These concern the geographical distribution of supernatural power and its association with certain landforms, natural phenomena and cultural features. His analysis further demonstrated that this model can account for two unusually large concentrations of sites and motifs: the Coso Range petroglyphs and the Carrizo Plain pictographs. But unanswered was the question of whether the model was applicable more widely, especially to smaller sites and localities made by different cultural groups. We documented and analyzed three petroglyph localities with seven small petroglyph sites in the southern Mojave Desert, California, to test this model. These sites are attributed to the Takic-speaking Cahuilla and Serrano tribes. Our study revealed a good fit between the expected natural and cultural variables associated with rock art site locations, with the number of such variables present at any given locale potentially correlated with the size of the individual sites. In addition to the research value of these results, this suggests that the model may be useful in predictive modeling of rock art site locations for heritage management purposes.

Authors: Sakai Yuki , Katsura Kouji , Kotake Masaaki , Toyama Akira
Published: January 2025

Objectives: The aim of this study was to investigate the incidence and severity of oral adverse events in outpatients receiving cancer drug therapy and the need for intervention by dental professionals. Methods: A questionnaire-based survey was conducted among patients who received cancer drug therapy at our hospital between September 1 and 30, 2022. The incidence and severity of oral adverse events and the need for intervention by dental professionals were investigated. The risk factors for these events were also analyzed. Results: Of the 216 patients who answered the questionnaire, 127 (58.8%) experienced oral adverse events such as dysgeusia, oral mucositis, and xerostomia. Of the patients who experienced oral adverse events, 53.5% showed that they wanted to improve their condition, 34.6% showed that the adverse events caused problems in their daily lives, and 26.8% wanted dental intervention. Thirty-two patients (25.2%) reported that the symptoms of these oral events were as severe as or more severe than those of other adverse events. The incidence of adverse oral events was significantly higher in patients treated with 5FU- and taxane-based regimens than in patients treated with other regimens. Conclusions: Our results suggest that oral adverse events have a significant impact on outpatients receiving cancer drug therapy. More than a quarter of outpatients receiving cancer drug therapy wanted oral management through dental interventions. In particular, patients receiving 5FU-, taxane-, and anthracycline-based regimens may require oral management by dental professionals.
A Training Algorithm for Locally Recurrent Neural Networks Based on the Explicit Gradient of the Loss Function
Authors: Montisci Augusto , Carcangiu Sara
Published: January 2025

In this paper a new algorithm for the training of Locally Recurrent Neural Networks (LRNNs) is presented, which aims to reduce computational complexity and at the same time to guarantee the stability of the network during the training. The main feature of the proposed algorithm is the capability to represent the gradient of the error in an explicit form. The algorithm builds on the interpretation of the Fibonacci’s sequence as the output of an IIR second-order filter, which makes it possible to use the Binet’s formula that allows the generic terms of the sequence to be calculated directly. Thanks to this approach, the gradient of the loss function during the training can be explicitly calculated, and it can be expressed in terms of the parameters, which control the stability of the neural network.
Thyroid Hormones and Brain Development: A Focus on the Role of Mitochondria as Regulators of Developmental Time
Authors: Vujovic Filip , Farahani Ramin
Published: January 2025

Thyroid hormones (TH) regulate metabolism in a homeostatic state in an adult organism. During the prenatal period, prior to establishment of homeostatic mechanisms, TH assume additional functions as key regulators of brain development. Here, we focus on reviewing the role of TH in orchestrating cellular dynamics in a developing brain. We provide evidence that developmental roles of the hormones are predominantly mediated by non-genomic mitochondrial effects of TH due to attenuation of genomic effects of TH that antagonise non-genomic impacts. We argue that the key function of TH signalling during brain development is to orchestrate the tempo of self-organisation of neural progenitor cells. Further, evidence is provided that major neurodevelopmental consequences of hypothyroidism stem from an altered tempo of cellular self-organisation.
Analysis of the Odor Levels at the Closest Receptors Depending on the Stack Terminal Types
Authors: Bellasio Roberto , Bianconi Roberto
Published: January 2025

This paper presents the results of a numerical analysis for evaluating the effects of different stack terminal configurations on the odor levels estimated at the receptors located close to the plant. Stack terminals may be of different types, for example vertical unobstructed, vertical with rain cap, horizontal, gooseneck or with any slope with respect to the vertical. The analysis has been performed with the LAPMOD dispersion model, which adopts a numerical plume rise scheme capable to simulate releases with any orientation. Two different sites have been considered, both located in northern Italy, one with almost flat orography, and one with relatively complex orography. The results show that the choice of the stack terminal has important effects on the odor levels predicted at the closest receptors.

Ferulic acid (FA) is an antimicrobial and antioxidant phenolic compound located in the cell walls of plants and therefore classified as a natural antioxidant. The objective of this study was to assess the antimicrobial and antioxidant potential of FA as a substitute for nitrites in the elaboration of dried meat (DM) . Four treatments were evaluated: DM without nitrites or FA (control treatment; CT), DM with nitrites (NT), DM with 0.05% of FA (FT05), and DM with 0.1% of FA (FT1). The antioxidant activity (ABTS, DPPH, and FRAP), lipid oxidation (TBARS), and microbiological quality were evaluated throughout DM shelf life. Protein, fat, and ash content were not different among NT, FT05, and FT1 (p > 0.05). NT and FT05 had lower moisture content (p < 0.05) compared to CT and FT1. And NT had the highest sodium content (p < 0.05). Regarding color, no differences (p > 0.05) were found among NT and FT05 in L* and a* values, but FT05 presented the highest b* value among all treatments (p < 0.05). However, color differences (ΔE) values between NT and FA treatments indicate that the color change is not noticeable to the human eye. Meanwhile, FT1 and FT05 exhibited the highest (p < 0.05) AA and the lowest lipid oxidation throughout their shelf life. Total aerobic mesophiles counts were detected only on day 1 and were lower (p < 0.05) in the treatments with FA. Finally, the change in the formulation of dried meat by using ferulic acid instead of nitrites was not sensorially detected by panelists. These findings suggest that incorporating natural antioxidants such as FA can improve the oxidative stability of dried meat, and it has a potential application as an antioxidant in meat products. However, further research is needed to study the effect of nitrite substitution using FA in combination with other potential natural antioxidants.
A Complex Structure for Two-Typed Tangent Spaces
Authors: Naudts Jan
Published: January 2025

This study concerns Riemannian manifolds with two types of tangent vectors. Let be given two subspaces of the tangent space with the property that each tangent vector has a unique decomposition as the sum of a vector in one subspace and a vector in the other subspace. Then these tangent spaces can be complexified in such a way that the theory of the modular operator applies and that the complexified subspaces are invariant for the modular automorphism group. Notions coming from Kubo-Mori theory are introduced. In particular, the admittance function and the inner product of the Kubo-Mori theory can be generalized to the present context. The parallel transport operators are complexified as well. Suitable basis vectors are introduced. The real and imaginary contributions to the connection coefficients are identified. A version of the fluctuation-dissipation theorem links the admittance function to the path dependence of the eigenvalues and eigenvectors of the Hamiltonian generator of the modular automorphism group.

Colorectal cancer is among the most prevalent causes of tumour-related deaths worldwide. Antiangiogenic therapy represents a cornerstone for metastatic CRC treatment and biomarkers are advocated for the optimization of this therapeutic strategy. In this observational prospective study, we applied an optimized flow cytometry (FC) protocol to explore the prognostic and predictive potential of blood circulating endothelial cells (CEC), circulating endothelial progenitor cells (CEPC) and related subsets in a cohort of patients with metastatic colorectal cancer (n=40). Computational FC analysis revealed a differential enrichment of blood cell clusters with a CD34+/CD45dim /CD117(c-kit)+ phenotype between responders and non-responders both to antiangiogenic and non antiangiogenic treatments. Intriguingly, our results show that a high percentage of annexin V negative cells in a putative circulating progenitor population with a CD34+/CD45dim/CD117+ phenotype was correlated with reduced response to systemic anticancer treatments (p 0.005) and worse overall survival (0.03). In addition, we observed increased blood concentrations of CD34+/CD45dim/CD117+/Annexin V- cells in patients with higher number of metastatic sites (p 0.03). Overall, these findings hold promise for the identification of novel blood based biomarkers for improved personalized treatment approaches in patients affected by metastatic colorectal cancer.
Transformed Imaginaries: Networked Integral Mission
Authors: Padilla-Deborst James
Published: January 2025

The church talks a great deal about transformation but often seems unsure about what precisely its end goal should look like. In imagining a new order, God’s kingdom come, it is sometimes rather vague about how it might get there. Our unequal world is still crying out for good news, for the church to fulfill its calling. Imagination is key to our ability as a church to hear and understand scripture and live out the gospel – but how do we examine and interrogate it? This article proposes that a sociotechnical imaginary can be a useful paradigm in our efforts to understand imagination and embody its imaginings. It will also set out a situated understanding of transformation as a method of integral mission with radically different implications for the privileged and the oppressed and offer a possible vision of a gospel-imagined end state towards which we might direct our course.

Published: January 2025

Background/Objectives: During the initial days in the COVID -19 pandemic, there existed no hospital-based policy or guidelines for management of dental emergency patients. The phase was marred with indecision and anxiety in general for dental patients and doctors as oral cavity along with saliva and indirect contact served as a harbor of transmission for the virus. Methods: The present study is retrospective, cross-sectional and descriptive in nature; the data was retrieved from the patients seeking emergency dental services during the COVID -19 lockdown (23rd of March 2020 to 23rd of April 2020) in primary and tertiary public hospitals of the National Guard Health Affairs in Riyadh, Saudi Arabia. Results: A total of 151 dental patients attended the outpatient/emergency during this period, The mean age of patients in the study was 31.4 (±19.0) years. Compared to Physicians, General dentist [OR 0.56, CI 0.29-10.47] were similar in giving an inappropriate diagnosis and treatment, whereas residents [OR 2.70, CI 1.65- 98.17] and resident endodontist [OR 2.30, CI 1.28- 78.11] were more likely to give appropriate diagnosis and treatment. Conclusions: The findings from the study highlight the need for a greater number of endodontists to be at the forefront of screening and providing dental care during such health catastrophes.

Increasing Electric Vehicle Charger Availability with a Mobile, Self-Contained Charging Station
Authors: Serrano Robert , Kavanaugh Declan , Wang Hongjie
Published: January 2025

As the adoption of electric vehicles (EVs) keeps increasing in recent years, two prevailing concerns of owners are charging station availability and reliability. During busy travel times, such as holiday weekends or during the summertime, it is common for owners to report long charger wait times due to limited site size and offline stations. Most charge point operators (CPOs) only install four to six chargers at a station, which leads to low redundancy. This study proposed a new movable, self-contained charging station design. This charging station can be deployed with short notice to temporarily increase capacity during busy times or emergencies such as evacuations due to natural disasters. With the goal of being self-sufficient, this study weighed the pros and cons of differing cell chemistries, sized the battery using charging data provided by the United States’ largest public CPO, and discussed the feasibility of a solar canopy.
Predicting Water Distribution and Optimizing Irrigation Scheduling in Turfgrass Management Using HYDRUS-2D
Authors: Cordel Jan , Anlauf Ruediger , Prämaßing Wolfgang , Broll Gabriele
Published: January 2025

The increasing reliance on water resources has necessitated improvements in turfgrass irrigation efficiency. This study aimed to compare measured field data with predicted data on irrigation water distribution in turfgrass rootzones to verify and enhance the accuracy of the HYDRUS-2D simulation model. Data were collected under controlled greenhouse conditions across unvegetated plots with two- and three-layered rootzone construction methods, each receiving 10 L m−2 h−1 of water for 1 h via subsurface drip irrigation (SDI) or sprinkler (SPR). Water content was monitored at various depths and time intervals. The hydraulic soil parameters required for the simulation model were determined through laboratory analysis. To improve model performance, sensitivity analysis, and model calibrations were conducted. The results indicated pronounced effects of the rootzone construction method and associated irrigation system on model quality performance. The calibrated models demonstrated good agreement with measured data, achieving model efficiency values (NSEs) up to 0.81 for SDI variants and 0.75 for sprinkler-irrigated variants. The findings suggest that HYDRUS-2D has potential as a cost-effective and efficient tool for evaluating irrigation strategies in turfgrass areas, although further refinement may be necessary for specific rootzone/irrigation combinations. This modeling approach can contribute to the optimization of irrigation scheduling and water use efficiency in turfgrass management.
Understanding Socio-Economic Struggles: A Study of the Experience of the Poor in Selected Sub-Saharan African Countries
Authors: Sandambi Nerhum
Published: January 2025

The study shows the exclusion of the poor in various governance programmes. It analyses some developing countries in Africa. In most of these countries, the poor are excluded from the economic policies implemented by their governments. The analysis shows that there is evidence of ongoing and persistent poverty, which is strongly supported by exclusive economic policies in line with extractive political institutions, but there is also a kind of institutional ignorance and discrimination of opportunities that has been strongly supported by patterns of rejection in the first place. There are also reasons why poor countries are overly dependent on Western countries to a significant degree. This dependence, however, makes a significant part of these countries corrupt and strongly aligned with exclusive policies and extractive institutions.

ste artículo examina los patrones y niveles de fecundidad según el tipo de unión conyugal y clase socioeconómica entre mujeres colombianas. Se enfoca especialmente el estrechamiento de algunas de las brechas que antes distinguían el comportamiento de la fecundidad en las diferentes clases socioeconómicas. Utilizando los datos de Demographic and Health Survey (DHS) para 1995, 2005 y 2015, se analizan los cambios en el contexto en que ocurre la reproducción que reflejan transformaciones en los valores que guían la formación de la familia, respaldadas por marcos legales. Hubo un aumento generalizado de las uniones libres en todos los grupos sociales a lo largo de las décadas. También se demuestra que las uniones libres pasaron a tener una mayor participación en la Tasa Global de Fecundidad (TGF) en comparación con los matrimonios, siendo ellas responsables del 57,5 % de la fecundidad global colombiana, es decir, un 39,4 puntos porcentuales mayor que la participación de las mujeres casadas en la TGF en el año más reciente. Aparentemente, hay incluso más niños naciendo fuera de uniones de cualquier tipo que dentro del matrimonio.

Published: January 2025

Archery athletes train their physique and technique in order to perform a series of bow and arrow pulls to the maximum, but athletes who can perform movements well during training may not necessarily be able to do it perfectly during the match. Athletes' concentration can be disrupted by various things when competing and affect the performance and achievements of athletes. The ability to concentrate is something that can be trained through mental training. This study aims to test whether there is an effect  of Mindfulness Meditation, as one of the mental training methods, on the concentration of archery athletes. This study uses an experimental method with a pretest-posttest control group design. The subject of this study is 30 athletes from the Unimed Archery Club who are divided into experimental and control groups. The instrument used to measure the concentration of athletes is the Grid Concentration Exercise. Data were obtained by conducting pretest and posttest on both groups. Mindfulness Meditation  treatment was given only to the experimental group. The results of the Wilcoxon  Test analysis showed that there was a difference in concentration scores between after and before treatment in the experimental group (Sig.=0.027, p<0.05), meaning that the hypothesis "there is an effect of Mindfulness Meditation on concentration in Unimed Archery Club Archery Athletes" was accepted. The experimental group had  a higher average gain score than the control group (5.5>0.76), which showed that Meditation Mindfulness had an effect on increasing the concentration of Archery athletes.

INTEGRATED MEASUREMENT SYSTEM FOR ATHLETE HEALTH: HEART RATE, BLOOD OXYGEN, AND BODY TEMPERATURE MONITORING
Authors: M.Ilyasa  , Ockta Yovhandra
Published: January 2025

Athlete health monitoring is critical for optimizing performance and ensuring physical well-being. This study presents an integrated non-invasive system designed to measure key physiological parameters: heart rate, blood oxygen saturation (SPO2), and body temperature. Utilizing infrared LED and photodiode sensors placed on the fingertip, the system detects changes in blood volume, correlating them with heart rate fluctuations. Pulse oximetry, employing red and infrared light wavelengths, accurately measures SPO2 levels by analyzing light absorption through finger tissues. Results from testing show promising accuracy with an average error of 0.89% for SPO2 measurements and 3.095% for heart rate measurements. Body temperature readings exhibit an average error of 0.78%, underscoring the system's reliability in non-invasively monitoring temperature changes. Challenges such as environmental influences and sensor calibration are addressed to ensure consistent and precise measurements. Future enhancements may incorporate advanced signal processing techniques and artificial intelligence to further refine measurement accuracy and reliability. This integrated system holds significant potential for enhancing athlete health management, aiding in early detection of physiological anomalies, and optimizing performance through real-time health monitoring
