title: An integrated data-driven workflow for kinetic model development and optimisation: theory and application to OMEs combustion

description: The development of computationally efficient kinetic mechanisms for alternative fuels remains a critical bottleneck for large-scale CFD simulations in engine design. This work presents a novel integrated data-driven workflow that automates kinetic mechanism development by coupling chemical lumping, skeletal reduction, and parameter optimisation within a unified framework, demonstrated through a compact OME<sub>2</sub> combustion mechanism. Using the SciExpeM data ecosystem, the workflow automatically manages mechanism construction, reduction, and optimisation with minimal manual intervention. The approach treats aggressive skeletal reduction as the foundation for two-stage optimisation, where temporary accuracy loss is systematically recovered through targeted parameter adjustment within physically consistent uncertainty bounds. The integrated workflow achieved a decrease in the number of species from 150 to 55 using DRGEP-based reduction, followed by evolutionary parameter optimisation through OptiSMOKE++. Comprehensive validation against experimental data spanning ignition delay times, jet-stirred reactor speciation, and laminar flame speeds demonstrated reliability across operating conditions relevant to compression ignition engines (650–1700 K, 1–50 atm, <i>ϕ</i> = 0.3–2.0). The optimised mechanism successfully recovered the accuracy lost during reduction, particularly in the critical intermediate temperature regime (770–910 K). The integrated workflow further improved the traditional size-accuracy trade-off through systematic parameter recalibration, achieving computational efficiency for CFD applications while maintaining chemical fidelity comparable to detailed mechanisms. This methodology establishes a foundation for rapid development of compact kinetic mechanisms for alternative fuels with automated workflows ensuring physical consistency.

title: An empirical study of cognitive load and constraint-driven innovation in the early phase of product design within a digitally mediated medium

description: Digitally mediated design mediums have revolutionized product design, but their cognitive impact during early concept design stages remains unclear. This study employs cognitive load theory (CLT) and constraint-driven cognition to examine how traditional (TD) and digitally mediated (DM) mediums influence cognitive load, problem-solving, and design outcomes. A quasi-experimental study with 16 design students, divided into TD and DM groups, used two distinct design tasks. Results revealed three key findings. First, the DM medium imposed a significantly higher extraneous cognitive load due to attentional fragmentation and interface management, consuming working memory resources critical for creative synthesis. Second, a fundamental strategic divergence emerged: the TD group engaged in problem-driven cognition through material constraints, yielding higher conceptual novelty (63% vs. 25%) and five times more sustainability considerations. The DM group used solution-driven strategies, leading to more derived outcomes. Third, the cognitive impact was task-dependent; digital tools reduced intrinsic load for well-defined mechanical tasks but offered no advantage for open-ended aesthetic tasks. This study suggests design mediums function as active cognitive environments, not neutral tools. A reevaluation of design education and practice is essential, promoting digital metacognition, retaining tactile skills, and developing hybrid processes that leverage the distinct cognitive benefits of each medium.

title: Factors influencing the presence and relative abundance of <i>Didymosphenia geminata</i>: impact on the composition of diatom assemblages over a broad latitudinal gradient in Chilean rivers

description: This study explored the abiotic factors influencing <i>Didymosphenia geminata</i> blooms and the combined effect of <i>D. geminata</i> and abiotic factors on local diatom assemblages in 13 Chilean watersheds across a broad latitudinal range (37°–47° S). To understand the multi-scale drivers, we used generalized linear mixed-effects models to assess the abiotic factors most influential on <i>D. geminata</i> presence and relative abundance. We then explored the effects of <i>D. geminata</i> and abiotic factors on the α- and β-diversity of diatom assemblages using generalized linear models and permutational analyses of variance, respectively. Three watersheds lacked <i>D. geminata</i> and another three had low relative abundance. Seasonally, the relative abundance of <i>D. geminata</i> was significantly higher in spring than in autumn. We found positive correlations between elevation, river order, pH and <i>D. geminata</i> presence and relative abundance, while water temperature was negatively correlated with <i>D. geminata</i> relative abundance. Diversity indices were significantly influenced by watershed and to a lower extent by the presence of <i>D. geminata</i>. We found significant spatial (i.e. between watersheds along a south–north latitudinal gradient) and temporal (i.e. between seasons) variations in β-diversity of diatom assemblages. Moreover, increasing relative abundance of <i>D. geminata</i> in the assemblage was correlated with lower diatom diversity. In addition, the compositions of diatom assemblages with <i>D. geminata</i> were more alike and less variable than those in non-invaded sites. This study is a first attempt to understand the multi-scale drivers of diatom assemblages in Chilean lotic ecosystems.

title: Glacier-fed stream diatoms (Bacillariophyta) from the Rwenzori Mountains, Uganda, with the description of one new species from the genus <i>Neidium</i>

description: Glacier-fed streams (GFSs) are harsh environments hosting unique, highly specialized communities. Interestingly, glaciers and their GFSs are also present in Earth’s tropical regions, where environmental characteristics contrast with GFS conditions elsewhere. Yet, despite the unique and isolated nature of tropical GFSs, little is known about their inhabitants, even though they may disappear later this century with ongoing climate change. Here, we examined diatom communities from one of the last tropical African GFSs in the Rwenzori Mountains, Uganda, to characterize the composition and diversity of this unique system. Six sediment-associated biofilm samples were collected from two reaches of a stream draining the Mt. Stanley Glacier, and the resident diatom communities were studied morphologically using light and scanning electron microscopy, as well as through the sequencing of amplicons from extracted DNA (18S and <i>rbc</i>L). In general, morphological results agree well with barcoding results, but each individually provides irreplaceable insights. In total, we identify 24 morphotypes utilizing light microscopy, 101 diatom Amplicon Sequence Variants (ASVs) using 18S sequences, and 65 ASVs with <i>rbc</i>L. Across approaches, common genera include <i>Achnanthidium</i>, <i>Psammothidium</i>, <i>Neidium</i>, <i>Cymbopleura</i>, <i>Eunotia</i>, and <i>Pinnularia.</i> However, only about half of the diversity could be assigned to the species level across methodologies, including several of the most common taxa, indicating a high level of uniqueness. Accordingly, one of the most common taxa encountered is described here as a new species, <i>Neidium rwenzoriense</i> sp. nov. Our results emphasize the Rwenzori Mountains as a global hotspot for endemism, and the novelty of disappearing tropical GFSs as diatom habitats.

title: Past responses of modern phytoplankton and subfossil diatoms to volcanism in an Andean lake (central Chile)

description: Laguna del Maule is a volcanic basin lake in the Central Chilean Andes that contains a peculiar and poorly understood algal flora from an ecological perspective. We present a comprehensive list of modern phytoplankton and limnological parameters (measured in 2011 and 2015), as well as a subfossil diatom assemblage spanning the past ∼700 years. We examined the relationship between the past assemblages and two Holocene tephra layers, pH, and the impact of recent warming. Chlorophyll values (1.3–1.8 µg l<sup>−1</sup>) are indicative of an oligotrophic lake. Counts (past and modern specimens) totalled two hundred fifty-four taxa: Bacillariophyceae (239, mainly subfossil), Chlorophyta (4), Chrysophyta (3), Cryptophyta (3), Cyanophyta (3) and Dinophyta (2). Diatom groups included: twelve centric (the most abundant specimens) and two hundred twenty-seven pennate taxa; of the latter, thirty-three were araphid and one hundred and ninety-four were either monoraphid or biraphid. An increased richness was observed after deposition of the tephra layers, along with different diatom assemblages associated with each tephra. Alkaliphilous-circumneutral taxa dominated, in concordance with the alkaline basin conditions of Laguna del Maule. A recent megadrought brought a shift from planktic to benthic diatoms, as coastal areas expanded, fostering a higher diversity of biraphid genera. Records of past and present dynamics of Andean lacustrine microorganisms are necessary to further evaluate responses to critical global environmental change and for high-altitude aquatic ecosystem conservation efforts.
