Tighter Lower Bounds for Single Source Personalized PageRank
We study lower bounds for approximating the Single Source Personalized PageRank (SSPPR) query, which measures the probability distribution of an $α$-decay random walk starting from a source node $s$. Existing lower bounds remain loose-$Ω\left(\min(m, 1/δ)\right)$ for relative error (SSPPR-R) and $Ω\left(\min(n, 1/ε)\right)$ for additive error (SSPPR-A). To close this gap, we establish tighter bounds for both settings. For SSPPR-R, we show a lower bound of $Ω\left(\min\left(m, \frac{\log(1…

Restoration brings back fresh water, wildlife to degraded páramos in Ecuador
When the sheep were removed, the páramo — high-altitude ecosystems in the Andes — started to heal. Without their waste, water quality improved. Without their hooves compacting the soil, plants began to grow again. Before long, shy white-tailed deer arrived, drawn by the grasses and shrubs for food and shelter. Not long after, pumas reappeared. […]

Frisch verlobt, aber: - So viel bekommt Ronaldos Georgina im Trennungsfall #News #Nachrichten

Familie Thiele¹ mußte zu ihrem großen Bedauern 4 Mrd. Erbschaftssteuer zahlen, weil ihre Steuer­hinterziehungs­stiftung² nicht rechtzeitig fertig wurde.
Was die generelle Frage aufwirft: übertrifft der gesamt­gesellschaftliche Nutzen solcher Stiftungen im Mittel die Steuerausfälle für den Staat?³
Falls nicht sollten wir die Gesetzeslage ändern. Wird aber nicht passieren:
• die Union wird dagegen sein
• die SPD wird dafür sein, wenn sie in der Opposition ist, aber nicht,…

Fast Geometric Embedding for Node Influence Maximization
Computing classical centrality measures such as betweenness and closeness is computationally expensive on large-scale graphs. In this work, we introduce an efficient force layout algorithm that embeds a graph into a low-dimensional space, where the radial distance from the origin serves as a proxy for various centrality measures. We evaluate our method on multiple graph families and demonstrate strong correlations with degree, PageRank, and paths-based centralities. As an application, it turns …
