Energy supply security (ESS) is one of the pillars of the Energy Trilemma. Although crucial for the transition to sustainable energy systems, ESS is frequently overlooked in energy system design. This article introduces the ESS Pyramid, a hierarchical framework combining conceptual insights with quantitative metrics to assess supply security. The ESS Pyramid has five levels, including foundational elements, such as Self-Production and Autonomy, and higher-order requirements, such as System Adequacy, Self-Sufficiency, and Autarky. Specific metrics are defined for each level to facilitate quantitative assessments that can inform strategic planning and policy-making. Using Switzerland's energy transition as a case study, we demonstrate the practical application of the ESS Pyramid and how sustainable transitions can also increase energy supply security. This framework provides policymakers, energy planners, analysts, and researchers with a structured approach that complements the already detailed approaches to Sustainability and Equity, the other two pillars of the Energy Trilemma.

The accurate detection of trace perfluoroalkyl acids (PFAAs) in drinking water remains challenging due to nonspecific adsorption losses during pretreatment. This study systematically evaluated the adsorption behaviors of 11 PFAAs across five filtration membranes and four solid-phase extraction (SPE) sorbents to establish an optimized analytical protocol. Results demonstrated that glass fiber (GL) filters minimized PFAAs retention (94.

To a large extent, the food security and ecological balance of a region, particularly in agriculturally dominated areas, largely depend on the sustainable use and management of groundwater resources. However, in recent times, both natural and human-driven factors have heavily impacted the lowering of groundwater resources. Therefore, the present study has been carried out in a drought-prone region of Birbhum district, part of the red-lateritic agro-climatic zone of West Bengal, Eastern India, to delineate groundwater potential zones (GWPZs).

Testicular torsion is a urological emergency that occurs when the spermatic cord twists, cutting off blood supply to the testicle, and it requires immediate surgical intervention to prevent irreversible damage. Although it typically presents with sudden, severe scrotal pain and swelling, atypical presentations can complicate diagnosis and delay treatment. We report the case of a 25-year-old male who presented to the emergency department with a sudden onset of left lower abdominal pain and left inguinal swelling.

Backgrounds And Objectives: The enhanced-view totally extraperitoneal technique (eTEP) has gained popularity as a novel minimally invasive ventral hernia repair approach. However, this procedure becomes technically demanding once the view is no longer maintained, due to incidental pneumoperitoneum caused by peritoneal injury during the surgery. In an attempt to overcome this technical issue, we report laparoscopic extraperitoneal repair with upfront coring out of hernia defect (LERCO) where the intraperitoneal coring out of the hernia defect precedes the regular eTEP for the treatment of midline incisional ventral hernia.

Agricultural supply chains face significant challenges in achieving food security and sustainability, particularly due to climate change and waste production. Effectively managing these supply chains, especially in the context of uncertainties, is crucial for optimizing resource use and minimizing waste. This research develops a multi-objective optimization for designing a sustainable and responsive closed-loop agricultural supply chain network, focusing on jujube products under uncertain conditions.
