Blow up and quenching for a problem with nonlinear boundary conditions

open access: yesElectronic Journal of Differential Equations, 2015
In this article, we study the blow up behavior of the heat equation $ u_t=u_{xx}$ with $u_x(0,t)=u^{p}(0,t)$, $u_x(a,t)=u^q(a,t)$. We also study the quenching behavior of the nonlinear parabolic equation $v_t=v_{xx}+2v_x^{2}/(1-v)$ with $v_x(0,t)=(1-v(

Investigation of Stray‐Light Patterns in the eROSITA X‐Ray Cameras

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the soft X‐ray instrument aboard the Spectrum‐Roentgen‐Gamma (SRG) mission, developed under the responsibility of the Max Planck Institute for Extraterrestrial Physics (MPE).

Application of the Oval Femoral Tunnel Technique in Anatomical Single‐Bundle Anterior Cruciate Ligament Reconstruction: Fujian Union Technique

open access: yesArthroscopy Techniques, EarlyView.
Abstract Anterior cruciate ligament (ACL) reconstruction aims to restore both the anatomical footprint and the biomechanical stability of the knee joint. However, traditional femoral tunnel techniques, typically round in shape, often fail to accurately replicate the oval femoral insertion of the ACL. This discrepancy can compromise rotational stability

String Figuring young children's perspectives of quality in English early childhood education and care

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

From liquid learning to weaving learning: Negotiating meanings of Children's learning in family travel

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Children's learning increasingly extends into everyday informal settings, but what counts as learning in these contexts remains insufficiently understood. Focusing on family travel as a mobile and socioculturally situated informal learning context, this study adopts a sociocultural perspective and uses liquid learning as a sensitising concept ...

On the blow-up rate for fast blow-up solutions arising in an anisotropic crystalline motion

open access: yes, 2020
We consider the asymptotic behavior of motion of polygonal convex curves by crystalline curvature in the plane. There appear spontaneously two types of singularity: one is single point extinction and the other is degenerate pinching.

A Modular Micro‐Chemostat System for High‐Throughput Continuous Cultivations

open access: yesBiotechnology and Bioengineering, EarlyView.
This study presents and demonstrates a modular 12‐channel micro‐chemostat, designed to be used by Genesis, a Robot Scientist developed to automate scientific research in yeast systems biology. The bioreactor performance fulfilled the predefined requirements, and the empirical results from the biological experiments were consistent with the literature ...

Animal empathy reconsidered: a multidimensional profile account

open access: yesBiological Reviews, EarlyView.
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

A Universal and Actionable Measure of Corporate Sustainability for Strategic Decision Making

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Managers require a universal, comparable, and decision‐useful measure of corporate sustainability that can reliably inform business strategy, yet such a tool remains absent in the literature and current practice. This paper introduces a comprehensive and operational metric—grounded in Goertz's Basic Framework for developing social science ...
