    The domestic sector accounts for a third of the UK's energy consumption and with increasing pressure from net-zero targets, the potential of residential flexibility is more widely recognised by consumers, aggregators and governments. The development of near real-time metering systems and home energy management technologies provide new possibilities for residential demand-side control. Due to the increase in energy prices and government schemes for improving residential energy efficiency and flexibility, domestic consumers are more aware and willing to participate in balancing services. The aggregator business model is previously proven to be successful for commercial-scale markets, due to the adequate amount of flexibility during peak hours and the corresponding financial incentives. Similarly, the domestic aggregation market is expected to grow and there has been a few feasibility studies that demonstrate the benefits to the grid and economy. However, there is a need for a further in-depth study of the cost-effectiveness of residential aggregation to provide virtual power plant (VPP) actions to encourage the development of residential demand response (DR). Here, we model and compare profitable cost-effective VPP methods using residential aggregation through the integration of a novel market entity called the residential aggregator

Neutrophil trafficking and immune function are intimately linked to cellular biophysical properties. This study used proteomic, biomechanical and functional analyses to further define neutrophil heterogeneity in the context of SLE. Methods: Proteomic/phosphoproteomic analyses were performed in healthy control (HC) normal density neutrophils (NDNs), SLE NDNs and autologous SLE LDGs. The biophysical properties of these neutrophil subsets were analysed by real-time deformability cytometry and lattice light-sheet microscopy. A two-dimensional endothelial flow system and a three-dimensional microfluidic microvasculature mimetic (MMM) were used to decouple the contributions of cell surface mediators and biophysical properties to neutrophil trafficking, respectively. Results: Proteomic and phosphoproteomic differences were detected between HC and SLE neutrophils and between SLE NDNs and LDGs. Increased abundance of type 1 interferon-regulated proteins and differential phosphorylation of proteins associated with cytoskeletal organisation were identified in SLE LDGs relative to SLE NDNs. The cell surface of SLE LDGs was rougher than in SLE and HC NDNs, suggesting membrane perturbances. While SLE LDGs did not display increased binding to endothelial cells in the two-dimensional assay, they were increasingly retained/trapped in the narrow channels of the lung MMM. Conclusions: Modulation of the neutrophil proteome and distinct changes in biophysical properties are observed alongside differences in neutrophil trafficking. SLE LDGs may be increasingly retained in microvasculature networks, which has important pathogenic implications in the context of lupus organ damage and small vessel vasculopathy

    Systemic Lupus Erythematosus is an autoimmune disorder, occurring predominantly in women during reproductive age and characterized by the presence of antibodies in the serum against the nuclear components (ANA), leading to inflammation in kidney, brain, and skin manifestations. The diversity of the disease the clinical presentation with the accumulation of manifestations over time and the fluctuant disease course challenges many clinicians. Two cases of Systemic Lupus Erythematosus with different manifestations revealing, challenges in diagnostic, treatment, follow up and bleak prognosis are presented
