Advancing Ransomware Mitigation Through Hybrid Models: A Systematic Literature Review
Get PDFAbstract—Ransomware, particularly Crypto-ransomware, poses a severe and evolving threat to corporate networks, causing significant financial and operational disruption. Traditional detection and mitigation techniques are increasingly inadequate in addressing the dynamic nature of these attacks. This systematic review explores intelligent hybrid models designed to proactively detect and mitigate crypto-ransomware threats within corporate environments. These models combined Machine Learning (ML) algorithms, Software-Defined Networking (SDN), and diverse security frameworks to enhance detection accuracy and response efficiency. We highlight how the combination of deep learning, signature-based techniques, and anomaly detection in hybrid frameworks improves overall responsiveness and effectiveness. The review also identifies key advancements in the field while outlining persistent challenges such as scalability, real-time implementation, and adaptability to evolving ransomware tactics. Based on our findings, we propose future research directions including: (1) the development of adaptive hybrid models with continuous learning capabilities for real-time threat adaptation, (2) the implementation of collaborative threat intelligence sharing via SDN and ML technologies across corporate networks, (3) the adoption of advanced deep learning architectures such as Long Short-Term Memory (LSTM) networks for accurate classification of ransomware behaviors, and (4) the design of scalable, SDN-based defense systems capable of handling high-traffic corporate environments. These recommendations aim to improve the efficacy and resilience of hybrid detection models in the face of modern ransomware threats.

These findings highlight the need to strengthen awareness campaigns, improve sanitation infrastructure, and promote early screening in urban area
Gestion Des Déchets Des Mèches Face A L’élevage Des Poules Dans Les Milieux Paysans Congolais Exemple De La Région De Lusanga
Get PDFCette recherche met en lumière un problème environnemental dû à la mauvaise gestion de déchets de mèches synthétiques imitant les cheveux utilisées par les femmes pour la beauté. Mal gérés ces déchets des mèches présentent un danger face à l’élevage des poules. Au fait, ils sont à l’origine de l’amputation des pattes des poules avec des conséquences sur leur santé et la survie des poussins lorsqu’ils sont attaqués par le rapace. Nous avons remarqué que les poules et poussins sont plus concernés que les coqs. Nous en avons donné les raisons. Pour résoudre ce problème d’amputation des pattes, nous avons proposé aux paysans de Lusanga de surveiller leur poules en cas d’attaque dérouler et/ou dénouer les mèches autour de la patte. Enfin cette problématique était loin d’être close car ces suspens persistent :-Faudra-t-il interdire les mèches dans les villages ou bien-faudra-t-il éloigner les éleveurs des villages
Aspect De La Prise En Charge Des Péricardites Tumorale Au Chu-Jra Antananarivo
Get PDFRESUME Introduction : La péricardite maligne est une inflammation du péricarde due à une pathologie néoplasique qu’elle soit primitive ou métastatique. Encore peu étudiée à Madagascar, il est important d’en déterminer la prévalence, les manifestations cliniques, l’étiologie prédominante, les modalités de prise en charge et le pronostic. Il s’agit d’une étude rétrospective descriptive de 11 ans incluant les patients hospitalisés, référés ou vus en consultation à l’USFR cardio-vasculaire du CHU-JRA. Résultats: La péricardite néoplasique représentait 3,45% des hospitalisations et 35,17% des péricardites hospitalisées. Une prédominance masculine a été observée (sex-ratio de 1,2), avec une classe d’âge modale de 45-59 (54,22%). Seuls 30% étaient au stade de tamponnade péricardique. Un drainage avec biopsie péricardique a été réalisé dans 74,69% des cas. Le liquide péricardique était principalement sero-hématique et exsudatif, avec présence de cellules carcinomateuses dans 15.94% des cas. L’histologie du péricarde n’a confirmé aucune présence tumorale. Tous les patients présentaient une péricardite néoplasique secondaire et les cancers broncho-pulmonaire étaient l’étiologie la plus fréquente (37%) Le taux de décès était de 11%. Conclusion : La péricardite maligne est en augmentation à Madagascar. Une prise en charge multidisciplinaire précoce améliore la survie des patients déjà affaiblis par leur pathologie cancéreuse
Determination of Effective Planting Season Based on Optimum Soil Water Content in Lolong Guba Area, Buru Island
Get PDFOne agro-climatic aspect that needs to be considered in plant cultivation is the planting season. The study aimed to describe the land’s water balance and determine a productive planting season in the Lolong Guba area. This research uses data from the Lolong Guba region, consisting of data: climate for the 1994-2023 period, soil texture, and support. Data analysis was carried out in stages: calculating 75% probability rainfall using the ranking order method; calculation of land water balance using the modified Thorthwaite-Mather bookkeeping system; and determining the effective planting season based on soil water content conditions from the results of land water balance calculations. The research results show that the soil water deficit in the Lolong Guba area is very small during the period May to July, namely less than 5 mm/month and in December there is no water deficit. The optimal soil water content period lasts for 7 months, namely January to July. Thus, the Lolong Guba area has a planting season of 8 months starting in December and ending in July
In Vitro Conservation of Titan Arum (Amorphophallus titanum (Becc.))
Get PDFTitan arum (Amorphophallus titanum (Becc.)) was an endangered and endemic flora from the island of Sumatra, facing a significant risk of extinction. Conservation efforts for titan arum had been undertaken, including in vitro conservation through tissue culture. This study aimed to determine the appropriate concentration of paclobutrazol and MS media dose to achieve slow shoot growth in titan arum to support medium-term storage. The research was conducted from August to October 2024 at the Tissue Culture Laboratory, Andalas University. The experiment was arranged in a Factorial Randomized Block Design (RBD) consisting of two factors: the concentration of the growth inhibitor Paclobutrazol (PBZ) (0.0 ppm; 3.0 ppm; 5.0 ppm) and MS media doses (Full MS, ½ MS, ¼ MS). Data analysis was performed using an F-test at a 5% significance level. If the F-test showed significant differences, further testing was carried out using Duncan's Multiple Range Test (DMRT) at a 5% significance level. The results showed that various concentrations of PBZ could suppress shoot growth in Amorphophallus titanum Becc., with the percentage of explants forming shoots reaching 100%. The concentration of 5.0 ppm PBZ and full-dose MS was the most effective in inhibiting shoot growth of titan arum, with an average shoot height of 1.5 cm and the highest number of shoots observed at concentrations of 0 ppm and 3.0 ppm across all MS media doses. This research was crucial for the conservation of titan arum and encourages further studies on in vitro culture techniques
Parcours De Demande De Soin D’une Adolescente Survivantes De Viol Au Togo
Get PDFSurviving the storm or inner chaos can seem like a miracle, especially if you know the cause(s) but don't understand the 'me'. Battling your inner enemies - your emotions, thoughts and feelings - can mean being a survivor, a miracle survivor in short, of the extreme violence of sexual assault. The aim of this article was to describe the experience of a rape survivor through an in-depth and unique analysis. To achieve this, we have used the clinical method. The analysis of the information gathered leads us to say that: in this journey, P's character seems to be frozen in the infernal cycle of repeating the scenarios of the rape event. She shows signs of psychic containment failure (high IA%). This particularly affects the kinesthetic (sensation of something walking on the pubis and sometimes on the lower abdomen) and tactile (sensation of burning and discomfort during sex, difficulty in maintaining close body-to-body contact at the beginning of our clinical encounters) envelopes. Despite this, she shows a good capacity for mentalisation, i.e. she tries to contain and manage conflicts as best she can
Modélisation De La Précipitation Dans La Partie Sud-Ouest De Madagascar En Fonction De L’Humidité, De L’OLR, De La Chaleur Latente Et De La SST Par Forêt Aléatoire
Get PDFThis study aims to model precipitation in the southwest of Madagascar using explanatory climatic variables : humidity, Outgoing Longwave Radiation (OLR), latent heat, and Sea Surface Temperature (SST), through a Random Forest model. The goal is to understand the impact of these variables on precipitation variability and to predict them based on local climatic conditions. The Standardized Precipitation Index (SPI) was used to characterize climatic periods, distinguishing between normal years, dry years, and wet years from 1979 to 2018. The model’s performance was evaluated with an R² = 0.865, indicating a good explanatory capacity, and a SMAPE = 32.58%, which is deemed acceptable for climate forecasting. The results show that variables such as humidity, latent heat, and SST have a significant influence on precipitation in this region, highlighting the importance of these factors for understanding the local climate dynamics
The Impact of Smart Cities on Urban Development and Sustainability in Worldwide and Türkiye
Get PDFThis study explores how smart cities are shaping urban life and their role in making cities more sustainable. It looks at smart city applications in worldwide and Türkiye, focusing on energy efficiency, waste management, and transportation systems. The goal is to understand how these projects improve urban infrastructure, enhance quality of life, and support economic and social development. The research also considers key factors influencing their success, such as government investment in technology and active citizen participation. The results show that smart city initiatives significantly reduce energy consumption, improve waste management, and make transportation systems more efficient. These projects promote sustainability and contribute to economic growth and better living conditions. However, their success largely depends on how healthy governments invest in technology and how actively communities engage with these innovations. One limitation of the study is its focus on urban areas, as rural communities often have limited access to smart technologies. To make these projects more inclusive, future research should examine how smart city solutions can be adapted to different socio-economic and geographic contexts. Looking ahead, policymakers should focus on strategies that increase public engagement and expand technological access, ensuring smart cities have a more meaningful impact on urban development. Further research on the sustainability, security, and long-term effectiveness of these projects will help maximize their benefits and make cities more resilient and livable for the future. sheet.Keywords— Smart City, Sustainability, Urban Development, Technology Integration, Citizen Participatio
