Rethinking Water Scarcity Indicators to Improve SDG 6.4.2 Monitoring in Algeria

Abstract While water scarcity is widely perceived as a reality, its measurement remains a complex and debated issue, particularly in arid regions where data gaps and methodological inconsistencies persist. This study provides a structured assessment of water scarcity in Algeria b...

Occurrence and Genomic Characterization of Listeria monocytogenes ST121 in Animal-Derived Food Samples from Bejaïa, Algeria

Listeria monocytogenesis an important foodborne pathogen that can cause severe invasive disease in vulnerable populations. This study assessed the occurrence of L. monocytogenes in animal-derived foods collected in Bejaïa, Algeria, and characterized recovered isolates using whole...

Conflict between farmers and Barbary macaques (Macaca sylvanus) in Northern Algeria: threats and conservation implications

Abstract Human-wildlife conflict is a major challenge in conservation biology with ecological and socioeconomic consequences. The problem is particularly delicate when the animals involved are threatened with extinction and experiencing rapid habitat loss due to climate change an...

Experimental and numerical analysis of liquid sloshing within tank subjected to pitching motion

Liquid sloshing in partially filled tanks can generate large free surface oscillations, especially under pitch excitation. While extensive research has addressed sloshing in rigid containers, few studies focus on sloshing within flexible tanks or pure pitch-induced sloshing. This...

Tail Connectedness in European Equity Markets: Regime Persistence and the Role of Geopolitical Risk

Financial networks are typically summarised by a single average-regime connectedness estimate that treats transmission as symmetric across calm and turbulent markets. Using a quantile vector autoregression on nine European equity indices from 2000 to 2026, we show that crash-regi...

Improving ADRC Strategy for DC-Link Voltage Regulation in PV Grid-Tied Four-Leg Inverters Using an Adaptive Nonlinear High-Gain Observer

In practical photovoltaic grid-tied four-leg inverter systems (PV-GTFLIs), changes in radiation, temperature, and grid voltage magnitude cause significant disturbances, including DC-link voltage disturbance and power unbalance, which can impact the system’s dynamic responses, con...
