Exact Solutions for the Moving Firefighter Problem on Trees
Networks, EarlyView.ABSTRACT The moving firefighter problem (MFP) is a more realistic variant of the classic firefighter problem (FP), where firefighters require time for both travel and defense. Unfortunately, the only known exact solution for the MFP does not scale. In this paper, we establish that the MFP is NP‐complete on trees of maximum degree three and present four

Oikos, EarlyView.Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

Mineral Speciation for CO2 Captured by Potassium Hydroxide
ChemistryOpen, EarlyView.Multimodal and deconvolution analysis of the crystalline and amorphous mineral products from the rapid capture of CO2 in aqueous, aqueous‐ethanol, and aqueous‐acetone solutions of potassium hydroxide by complementary single‐crystal and powder X‐ray diffraction, and high field 1H, 13C, and 39K NMR, provides new insight into the speciation of both KHCO3‐

Schiff based derived homogeneous catalysts for ring‐opening terpolymerization
Polymer International, EarlyView.One‐pot synthesis of degradable terpolymers from l‐lactide, propylene oxide and CO₂ using diverse catalysts is described, revealing structure–property relationships for tailored applications in sustainable materials. Abstract In this study, we synthesized and evaluated a series of Schiff base cobalt catalysts for the terpolymerization of propylene ...

Rapid Communications in Mass Spectrometry, EarlyView.ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Optimal Homogeneous ℒp$$ {\boldsymbol{\mathcal{L}}}_{\boldsymbol{p}} $$‐Gain Controller
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Nonlinear ℋ∞$$ {\mathscr{H}}_{\infty } $$‐controllers are designed for arbitrarily weighted, continuous homogeneous systems with a focus on systems affine in the control input. Based on the homogeneous ℒp$$ {\mathcal{L}}_p $$‐norm, the input–output behavior is quantified in terms of the homogeneous ℒp$$ {\mathcal{L}}_p $$‐gain as a ...
