The curvature of gradient Ricci solitons [PDF]
Mathematical Research Letters, 2011 We study integral and pointwise bounds on the curvature of gradient shrinking Ricci solitons. As applications we discuss gap and compactness results for gradient shrinkers.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

ESG Thematic Bonds in Emerging Markets: Risk, Uncertainty, and Ambiguity
European Financial Management, EarlyView.ABSTRACT We examine the impact of risk aversion, ambiguity, and uncertainty (geopolitical and economic) on the ESG thematic bond markets in emerging countries. We analyze ESG sovereign (both USD and local currency denominated) and corporate bond markets on the aggregate and regional levels.

Forman–Ricci communicability curvature of graphs and networks
European Journal of Applied MathematicsGeometric parameters in general and curvature in particular play a fundamental role in our understanding of the structure and functioning of real-world networks. Here, the discretisation of the Ricci curvature proposed by Forman is adapted to capture the

Machine Learning Model for Predicting Postoperative Pain in Cases of Irreversible Pulpitis
International Endodontic Journal, EarlyView.ABSTRACT Aim Postoperative pain is a frequent clinical concern following endodontic treatment. This study aimed to develop and validate supervised machine learning models to predict the occurrence of postoperative pain in cases of irreversible pulpitis.

Collagen organisation in the fibrous joint capsules in the digits of the human hand
Journal of Anatomy, EarlyView.The function of the finger joints is important for daily life. In this review of the literature, we consider the role of collagen and its organization within the fibrous finger joint capsules of the interphalangeal (IP) joints and investigate the relationships between collagen orientation and joint function. Abstract Normal function of the hand and, in

The Journal of Physiology, EarlyView.Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

MathematicsIn this paper, we study the topology of steady gradient Ricci solitons with nonnegative sectional curvature. We apply a characterization theorem for the fundamental group of a positively curved steady gradient Ricci soliton that admits a critical point ...
