Low-dimensional modelling of a generalised Burgers equation

, 2007
Burgers equation is one of the simplest nonlinear partial differential equations—it combines the basic processes of diffusion and nonlinear steepening. In some applications it is appropriate for the diffusion coefficient to be a time-dependent function ...

Understanding the spacing of placodes in the eye: A comparative study across age and species

The Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

A Generalization of the Hopf-Cole Transformation

Symmetry, Integrability and Geometry: Methods and Applications, 2013
A generalization of the Hopf-Cole transformation and its relation to the Burgers equation of integer order and the diffusion equation with quadratic nonlinearity are discussed. The explicit form of a particular analytical solution is presented.

Editorial Commentary: The Femoral Impingement Index: Can Composite Morphology Better Capture Femoroacetabular Impingement Syndrome?

Arthroscopy, EarlyView.
Abstract Hip arthroscopy has undergone remarkable evolution over the past 2 decades. Improvements in patient selection, advanced imaging, labral preservation, capsular management, and osseous correction of femoroacetabular impingement syndrome have translated into consistently favorable outcomes for appropriately selected patients.

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT

Astronomische Nachrichten, EarlyView.
ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

How curriculum modifications shape educational pathways: Evidence from linked administrative data in Switzerland

British Educational Research Journal, EarlyView.
Abstract The increasing heterogeneity of learning needs and preconditions in inclusive mainstream classrooms entails that not all learners are equally able to meet the regular learning objectives. In response, various integrative measures have been implemented to tailor instruction to students' individual needs.

Understanding out‐of‐field teacher self‐efficacy beliefs: A person‐centred approach

British Educational Research Journal, EarlyView.
Abstract Teaching out‐of‐field (OOF) has been a widespread global phenomenon and a cause of concern for school leaders and policymakers due to the potential impact it has on teaching quality and student learning. However, research on how the nature of OOF teaching impacts various teachers' psychological attributes such as teacher self‐efficacy (TSE ...

Can Private Equity Deliver on Its Societal Ambitions? What We Know and Don't Know About Environmental, Social, and Governance Factor Integration in Private Equity

Business Strategy and the Environment, EarlyView.
ABSTRACT Private equity (PE) firms increasingly integrate environmental, social, and governance (ESG) factors in investment decisions and raise impact funds to address sustainability challenges. We review and integrate the growing body of literature on why, when, and how PE fund managers incorporate ESG factors into their investment strategies and ...

Can Sustainable Entrepreneurship Create Value for Enterprises? Examining the Roles of Corporate Reputation and Entrepreneurs' Self‐Promotion Behavior

Business Strategy and the Environment, EarlyView.
ABSTRACT To understand the heterogeneous performance outcomes of sustainable entrepreneurship, this study investigates the role of founder impression management. We develop and test a moderated mediation model, drawing on signaling and impression management theories, using a dual‐study design with longitudinal data (n = 217) and survey data (n = 259 ...
