A 3D method called mdMRS for post-processing Magnetic Resonance Spectroscopy data

Journal of Magnetic Resonance Open, 2023
The data obtained from a scanner for Magnetic Resonance Spectroscopy (MRS) is three-dimensional (3D) since the FID data from the scanner has spectrum values which are 2D complex numbers and 1D time values. This paper describes an MRS frequency-based post-

Biquadratic Transformations for Checking the Hurwitz Stability via the Schur Stability

Asian Journal of Control, EarlyView.
ABSTRACT Bilinear transformations such as the Möbius transformation have been used to study Hurwitz stability by means of Schur stability, or vice versa. However, the use of a well‐known Möbius transformation has pathological cases, hence Jalili–Kharaajoo and Araabi investigated and found a biquadratic transformation to study Schur stability by means ...

Physics in deformable spacetime: Physical laws emerging from the surface minimality principle and the masses of particles

Results in Physics
In this work, the study was focused on how deformable spacetime gives rise to physical laws, particularly quantum and special relativity. It was shown that both the Lorentz factor and quantum mechanics can emerge from the dynamical behavior of minimal ...

The Contingent Eco‐Innovation–Firm Performance Link: A Global Systematic Literature Review and Future Research Agenda

Business Strategy and the Environment, EarlyView.
ABSTRACT The relationship between eco‐innovation (EI) and firm performance (FP) is central to environmental management research, yet empirical evidence remains fragmented and highly context dependent. This article presents a global systematic literature review (SLR) of 541 empirical studies (2006–April 2025) to (i) diagnose the systematic sources of ...

Improving the area-preserving parameterization of rational Bézier surfaces by rational bilinear transformation

Graphical Models
To improve the area-preserving parameterization quality of rational Bézier surfaces, an optimization algorithm using bilinear reparameterization is proposed.

A Strategic Approach to Improving Interfacial Interactions in TPU/POSS Composites via Ball Milling of POSS

Polymer Engineering &Science, EarlyView.
Ball‐milling promotes uniform POSS dispersion in the TPU matrix, markedly improving the mechanical performance of TPU‐POSS composites. ABSTRACT We synthesized TPU/POSS composites through a two‐step process involving the ball milling of POSS to reduce its particle size, followed by in situ polymerization of TPU to reinforce the material.

Periodically, quasiperiodically, and randomly driven conformal field theories

Physical Review Research, 2021
In this paper and its upcoming sequel, we study nonequilibrium dynamics in driven (1+1)-dimensional conformal field theories (CFTs) with periodic, quasiperiodic, and random driving.

Creating a Masterpiece. The Road to (and Beyond) Woodward and Hoffmann's 1969 Angewandte Chemie Treatise

The Chemical Record, EarlyView.
This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.

AUGURAL TERRITORIES: On the Prophetic Organizing of the Mid‐range

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article I introduce the concept of augural territories to theorize the urbanism that emerged during pandemic lockdowns. I draw on ethnographic research in Madrid to examine how community‐based responses—including mutual aid networks, food pantries and neighbourhood associations—disrupted the spatial and temporal logics of territorial ...

GROWING GREEN IN US SUBURBIA: Property Value, Race and Domestic Landscaping Aesthetics in Mid‐Century America

International Journal of Urban and Regional Research, EarlyView.
Abstract Much of the current popular and academic literature on the provision of green spaces is dominated by the assumption that ‘nature’ is an unalloyed positive, and that socioeconomic and racial exclusion from access to green spaces is a problem of unequal spatial distribution rather than of the form and content of particular urban designs.
