A design tool for globally developable discrete architectural surfaces using Ricci flow
This paper presents an approach for the design of discrete architectural surfaces that are globally developable; that is, having zero Gaussian curvature at every interior node.

ABSTRACT User personas are important tools for user understanding in human‐computer interaction (HCI), and understanding how personas contribute to environmental sustainability across research and practice contexts is increasingly important. Our systematic review of 36 articles on persona research in environmental sustainability reveals four key ...

In 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 ...

Ricci Flow and Volume Renormalizability [PDF]
With respect to any special boundary defining function, a conformally compact asymptotically hyperbolic metric has an asymptotic expansion near its conformal infinity. If this expansion is even to a certain order and satisfies one extra condition, then it is possible to define its renormalized volume and show that it is independent of choices that ...

DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

POSITIVITY OF RICCI CURVATURE UNDER THE KÄHLER–RICCI FLOW [PDF]
In each complex dimension n ≥ 2, we construct complete Kähler manifolds of bounded curvature and non-negative Ricci curvature whose Kähler–Ricci evolutions immediately acquire Ricci curvature of mixed sign.

ABSTRACT The purpose of this paper is to discuss the micro‐ and macro‐outcomes for the standard neoclassical carbon tax (whose burden falls on the producers) versus the implication of a budget neutral, performance‐based EU Common Agricultural Policy (CAP) focusing on non‐CO2 emission (N2O and CH4, measured in CO2eq) reduction, especially in the ...

Optimising the Diagnosis of Sesame Seed Allergy With the Basophil Activation Test
The basophil activation test (using the activation marker CD203c) was the only test able to both exclude and confirm sesame seed allergy with precision. A negative skin prick test to sesame extract or tahini and undetectable IgE to Ses i 1 could not rule out sesame seed allergy.

A Spotlight on Yolk‐sac Tumors: Molecular Pathology, Current Diagnostics, and Novel Therapeutics
ABSTRACT Background Yolk‐sac tumors are an aggressive subtype of testicular cancer that significantly contribute to disease progression and therapy resistance, especially in adults. While testicular cancer generally has high cure rates with cisplatin‐based treatment, adult yolk‐sac tumors often appear as components of mixed tumors with poor response to
