Consequently, many applications that can enhance passengers’ safety and traffic flow are built upon this information. However, malicious nodes can manipulate the exchanged data to attack other nodes and disrupt the network’s normal behavior. For example, if an attacker broadcasts a falsified location for a vehicle, the functionality of applications that rely on accurate location sharing will be compromised, potentially leading to deadly accidents. Although numerous Misbehavior Detection Schemes (MDSs) have been proposed to detect position falsification attacks, their effectiveness remains limited for certain attack types, raising concerns given the safety-critical nature of VANET applications. This paper proposes a machine learning-based method for detecting position falsification attacks. The proposed approach evaluates four machine-learning algorithms using three feature vectors (FV1, FV2, and FV3) composed of selected and derived features extracted from Basic Safety Messages (BSMs), in addition to a novel confidence-based Received Signal Strength Indicator feature, termed RSSIConf. The RSSIConf feature assesses the reliability of a sender’s claimed position by comparing the measured RSSI with confidence intervals corresponding to the claimed sender–receiver distance. Experimental results show that the Random Forest classifier trained with FV2 features achieves the best overall performance, outperforming existing approaches with improvements ranging from 0.76% to 13.26% in accuracy and from 0.74% to 12.71% in F1-score across different position spoofing attack types. These improvements enhance the reliability of misbehavior detection and contribute to safer and more trustworthy VANET communications.","source":"DOAJ","year":2026,"language":"","subjects":["Medicine","Science"],"doi":"10.1038/s41598-026-39867-9","url":"https://doi.org/10.1038/s41598-026-39867-9","is_open_access":true,"published_at":"","score":70},{"id":"doaj_10.3969/j.issn.1673-3819.2025.03.013","title":"Weapon equipment question answering system based on BERT and knowledge graph","authors":[{"name":"WANG  Bo, JIANG  Xuping, HUANG  Qihong"}],"abstract":"Knowledge of weaponry and equipment is a crucial basis for formulating equipment utilization strategies and development pathways.

In this pathogenic process, the dysregulated interaction between adipocytes and adipose-resident immune cells plays a critical regulatory role; however, the underlying mechanisms governing this abnormal interaction remain largely unknown. In this study, we showed that upregulated β2-microglobulin expression in hypertrophic adipocytes during obesity not only mediated the activation of adipose-resident CD8+ T cells in a cell contact-dependent manner but also facilitated iron overload and the ferroptosis of adipocytes, thereby promoting the M1 polarization of adipose tissue macrophages. Conversely, specific ablation of β2-microglobulin in adipocytes effectively suppressed the activation and accumulation of adipose-resident CD8+ T cells, as well as adipocyte ferroptosis and M1 polarization, ultimately preventing high-fat diet-induced obesity and its related inflammation and metabolic disorders. Additionally, adeno-associated virus-mediated adipose-targeted knockdown of β2-microglobulin has been demonstrated to therapeutically alleviate high-fat diet-induced obesity, as well as its related chronic inflammation and metabolic disorders. Furthermore, our bioinformatic analysis of human adipose transcriptome data revealed a strong correlation between adipose β2-microglobulin and obesity. More importantly, β2-microglobulin is significantly upregulated in adipocytes isolated from patients with obesity. Thus, our findings highlight the pivotal role of adipocytes in obesity-associated chronic inflammation and metabolic disorders via β2-microglobulin-dependent mechanisms.","source":"DOAJ","year":2025,"language":"","subjects":["Medicine","Biology (General)"],"doi":"10.1038/s41392-025-02486-3","url":"https://doi.org/10.1038/s41392-025-02486-3","is_open_access":true,"published_at":"","score":69},{"id":"doaj_10.3390/v17010015","title":"Epidemiology and Ecology of Toscana Virus Infection and Its Global Risk Distribution","authors":[{"name":"Xue-Geng Hong"},{"name":"Mei-Qi Zhang"},{"name":"Fang Tang"},{"name":"Si-Hui Song"},{"name":"Jia-Yi Wang"},{"name":"Zhen-Yu Hu"},{"name":"Li-Ming Liu"},{"name":"Xiao-Ai Zhang"},{"name":"Yi Sun"},{"name":"Li-Qun Fang"},{"name":"Wei Liu"}],"abstract":"Toscana virus (TOSV), a member of the \u003ci\u003ePhlebovirus\u003c/i\u003e genus transmitted by sandflies, is acknowledged for its capacity to cause neurological infections and is widely distributed across Mediterranean countries.

Many studies about microvascular invasion currently focus on preoperative and prognosis prediction of microvascular invasion using artificial intelligence. In this paper, we review the definition and staging of microvascular invasion, especially the diagnosis of it by using artificial intelligence. In preoperative prediction, deep learning based on multimodal data modeling of radiomics-screened features, clinical features, and medical images is currently the most effective means. In prognostic prediction, pathology is the gold standard, and the techniques used should more effectively utilize the global features of the pathology images.","source":"DOAJ","year":2023,"language":"","subjects":["Neoplasms.

This yielded a novel behavioral interaction: pre-saccadic stimulus repetition neutralizes perisaccadic time compression. We then tested these results against simulations of the above models. Our data yielded low correlations against scalar model simulations, high but non-specific correlations for our feedforward neural network, and correlations that were both high and specific for a vector model based on identity of objective and subjective time.

The purpose of the study is to determine how adding a parasitic strip next to the flat surface metallic feed would affect various far- and near-field antenna characteristics. Initially, the basic antenna design, i.e., the T-shape feed known as antenna A, produced a 4.81% impedance matching bandwidth (|S\u003csub\u003e11\u003c/sub\u003e| −10 dB). Due to the narrow and undesirable results of the initial antenna design, antenna-A was updated to the antenna-B design, i.e., Yagi-Uda. The antenna-B produced a decent result (7.89% S\u003csub\u003e11\u003c/sub\u003e) as compared to antenna-A but still needed the bandwidth widened, for this, a parasitic patch was introduced next to the Yagi-Uda antenna on the rectangular DRA at an optimized location to further improve the results. This arrangement produced circular polarization (CP) waves spanning a broad bandwidth of 28.21% (3.59–3.44 GHz) and a broad impedance |S\u003csub\u003e11\u003c/sub\u003e| bandwidth of around 29.74% (3.71–3.62 GHz). These findings show that, in addition to producing CP, parasite patches also cause the return loss to rise by a factor of almost three times when compared to results obtained with the Yagi-Uda-shape feed alone. Computer simulation technology was used for the simulation (CST-2017). The planned antenna geometry prototype was fabricated and measured. Performance indicators show that the suggested antenna is a good fit for 5G applications. The simulated outcomes and measurements match up reasonably.","source":"DOAJ","year":2022,"language":"","subjects":["Mechanical engineering and machinery"],"doi":"10.3390/mi13111913","url":"https://www.mdpi.com/2072-666X/13/11/1913","is_open_access":true,"published_at":"","score":66},{"id":"doaj_10.37540/njips.v5i1.121","title":"Education for Sustainable Development and Social Tolerance: Evidence from Teacher Education Institutions in Pakistan","authors":[{"name":"Amber  Jamshaid"}],"abstract":"Education for sustainable development is an evolving notion in teacher education that highlights the need for tolerance, acceptance, and diversity.

Using our predictive algorithms we confirmed that the future energy and exergy flow characterizations could be generated using the NNs, which was validated through simulation using two separately created datasets, one for training and one for testing. We then used the NNs to implement a model predictive control (MPC) framework to flexibly operate the vehicles thermal coolant loop (TCL), subject to exergy destruction. In this way we could tailor the performance of the vehicle to accommodate a more mission effective solution or a less energy intensive solution. The MPC resulted in a more effective solution when compared to six other simulated conditions, which consumed less exergy than two of the six cases.

Mentees report positive impacts from mentorship programs, yet institutions and societies may struggle to meet their mentees’ needs due to factors such as mentor fatigue and lack of mentor training. To address this in our own professional society, the Association of Pediatric Program Directors, we developed a mentor toolkit in order to utilize a variety of mentoring models, provide faculty development for midlevel mentors, and offer guidance to mentees. Methods Most of these tools were designed to be administered in an interactive format such as a workshop or seminar with think-pair-share opportunities. The toolkit begins by providing a definition of mentoring and reinforcing the benefits and the characteristics of effective mentoring relationships. Next, we discuss the important role that mentees have in creating and maintaining effective mentoring relationships (i.e., mentee-driven mentoring). We then introduce a mentoring mosaic activity designed to help mentees examine their professional network and think about how they might expand it to fulfill the spectrum of their mentoring needs. Next, we present guidelines for the implementation of four mentoring models that can be used within one's institution: traditional dyadic mentoring, peer group mentoring, meet the professor mentoring, and speed mentoring. We then provide tools that can be used to help facilitate effective mentoring development. Results This toolkit has successfully served as a self-guided resource at national meetings for many years, garnering positive feedback from mentors and mentees alike. Discussion The principles and methods are easily generalizable and may be used to guide mentorship programs within institutional and professional societies, as well as to assist mentors and mentees in optimizing their individual mentoring relationships.","source":"DOAJ","year":2016,"language":"","subjects":["Medicine (General)","Education"],"doi":"10.15766/mep_2374-8265.10459","url":"http://www.mededportal.org/doi/10.15766/mep_2374-8265.10459","is_open_access":true,"published_at":"","score":60},{"id":"doaj_10.18667/cienciaypoderaereo.433","title":"Introducción a la teoría VLM (Vortex Lattice Theory)","authors":[{"name":"Santiago Pinzón"}],"abstract":"Los métodos de panel han sido ampliamente utilizados en la industria y se han establecido desde la década de 1970 en el cálculo y el análisis aerodinámico.

Fully distributed phased array radars demand the distribution of various signals in radio frequency (RF) and digital domain for real time operation. This is normally achieved through complex and bulky coaxial distribution networks. In this work, we intend to tap the inherent advantages of fiber links with wavelength division multiplexed (WDM) technology and a feasibility study to adapt these links for radar applications is carried out. This is done by analysing various parameters like amplitude, delay, frequency and phase variation response of various radar waveforms over WDM links. This also includes performance evaluation of non-linear frequency modulation (NLFM) signals, known for better signal to noise ratio (SNR) to specific side lobe levels. NLFM waveforms are further analysed using pulse compression (PC) technique. Link evaluation is also carried out using a standard simulation environment and is then experimentally verified with other waveforms like RF continuous wave (CW), pulsed RF and digital signals. Synchronization signals are generated from this variable duty cycle digital signals during real time radar operation. During evaluation of digital signals, variable transient effects for different duty cycles are observed from an amplifier configuration. A suppression method is proposed to eliminate this transient effects. Further, the link delay response is investigated using different lengths of fiber spools. It can be inferred from the experimental results that WDM links are capable of handling various signals significant to radar applications.","source":"DOAJ","year":2015,"language":"","subjects":["Military Science"],"doi":"10.1016/j.dt.2014.09.002","url":"http://www.sciencedirect.com/science/article/pii/S2214914714000981","is_open_access":true,"published_at":"","score":59},{"id":"doaj_SOLDIERS%27+CODES+OF+CONDUCT+IN+DIFFERENT+COUNTRIES+AROUND+THE+WORLD.+A+COMPARATIVE+OUTLOOK","title":"SOLDIERS' CODES OF CONDUCT IN DIFFERENT COUNTRIES AROUND THE WORLD.

As this soldier has the right to legally use a powerful lethal force, a lot is required from him, which is normal. He is now most often a professional. He has mainly to master perfectly his weapons, to respect the Law of Armed Conflicts and to apply the principle of humanity. But his leaders have to guide him and his Nation to understand and support him.","source":"DOAJ","year":2014,"language":"","subjects":["Military Science"],"url":"http://journal.dresmara.ro/issues/volume5_issue1/01_mompeyssin.pdf","is_open_access":true,"published_at":"","score":58},{"id":"doaj_10.18667/cienciaypoderaereo.24","title":"Economista: Actual y del mañana una experiencia docente","authors":[{"name":"Henry Acuña Barrantes"}],"abstract":"A lo largo de este artículo de reflexión, se analizará la profesión y el nacimiento de la economía desde un punto de vista ilustrativo. Si bien la economía se constituyó como ciencia a mediados del siglo XVIII, la ansiedad por los procesos económicos en las sociedades se remonta a las civilizaciones de Grecia y Roma. El origen del pensamiento económico moderno tiene su inicio en la antigua Grecia. Los filósofos griegos fueron los primeros en analizar y reflexionar acerca de distintas cuestiones relacionadas con lo que hoy se conoce como economía. En este sentido, este escrito resalta la profesión del economista, su participación en otras disciplinas, como los retos que deberán asumir quienes están en el ejercicio, partiendo de una experiencia como docente e investigador en el área de la economía histórica desde hace ya cerca de 10 años.","source":"DOAJ","year":2012,"language":"","subjects":["Motor vehicles.
