The Extremal Number of Cycles with All Diagonals
(2024)International Mathematics Research NoticesIn 1975, Erdos asked the following question: What is the maximum number of edges that an n-vertex graph can have without containing a cycle with all diagonals? Erdos observed that the upper bound O(n(5/3)) holds since the complete bipartite graph K-3,K-3 can be viewed as a cycle of length six with all diagonals. In this paper, we resolve this old problem. We prove that there exists a constant C such that every n-vertex graph with at least ...Journal Article -
Warm conveyor belt characteristics and impacts along the life cycle of extratropical cyclones: case studies and climatological analysis based on ERA5
(2024)WEATHER AND CLIMATE DYNAMICSThis study presents a systematic investigation of the characteristics and meteorological impacts of warm conveyor belts (WCBs). For this purpose, we compile a new WCB climatology (1980-2022) of trajectories calculated with the most recent reanalysis dataset ERA5 from the European Centre for Medium-Range Weather Forecasts (ECMWF). Based on this new climatology, two-dimensional masks are defined that represent the inflow, ascent, and outflow ...Journal Article -

Biocatalytic Synthesis of L-Pipecolic Acid by a Lysine Cyclodeaminase: Batch and Flow Reactors
(2024)ChemCatCheml-Pipecolic Acid (l-PA) is a valuable building block for the synthesis of pharmaceuticals such as anesthetics and immunosuppressants. Thus, more efficient and greener strategies are desired for its production. Herein, we have applied a previously engineered variant of the Lysine Cyclodeaminase from Streptomyces pristinaespiralis (e-SpLCD) for the bioconversion of l-Lysine into l-PA. The reaction can be performed by the free e-SpLCD reaching ...Journal Article -
Isotopic evidence for seasonal water sources in tree xylem and forest soils
(2024)EcohydrologyForest trees greatly influence both the routing of water downward into the subsurface and the re-routing of water upward through water uptake and transpiration. To reveal how the subsurface soil water pools used by trees change across seasons, we analysed 2 years of stable isotope ratios of precipitation, soil water from different depths (using both bulk sampling and suction-cup lysimeters), and xylem in a mixed beech and spruce forest. ...Journal Article -
Mechanoregulation analysis of bone formation in tissue engineered constructs requires a volumetric method using time-lapsed micro-computed tomography
(2024)Acta BiomaterialiaBone can adapt its microstructure to mechanical loads through mechanoregulation of the (re)modeling process. This process has been investigated in vivo using time-lapsed micro-computed tomography (micro-CT) and micro-finite element (FE) analysis using surface-based methods, which are highly influenced by surface curvature. Consequently, when trying to investigate mechanoregulation in tissue engineered bone constructs, their concave surfaces ...Journal Article -
Silver-doped CdSe magic-sized nanocrystals
(2024)The Journal of chemical physicsMagic-sized nanocrystals (MSNCs) grow via jumps between very specific sizes. This discrete growth is a possible avenue toward monodisperse nanomaterials that are completely identical in size and shape. In spite of this potential, MSNCs have seen limited study and application due to their poor optical properties. Specifically, MSNCs are limited in their range of emission wavelengths and commonly exhibit poor photoluminescence quantum yields ...Journal Article -
Unifying model for the rheological behavior of hygroresponsive materials
(2024)Physical Review EHygroresponsive materials exhibit a complex structure-To-property relationship. The interactions of water within these materials under varying hygric and mechanical loads play a crucial role in their macroscopic deformation and final application. While multiple models are available in literature, many lack a comprehensive physical understanding of these phenomena. In this paper, we introduce a stick-slip fiber bundle model that captures ...Journal Article -
Generative Bayesian modeling to nowcast the effective reproduction number from line list data with missing symptom onset dates
(2024)PLoS Computational BiologyThe time-varying effective reproduction number Rt is a widely used indicator of transmission dynamics during infectious disease outbreaks. Timely estimates of Rt can be obtained from reported cases counted by their date of symptom onset, which is generally closer to the time of infection than the date of report. Case counts by date of symptom onset are typically obtained from line list data, however these data can have missing information ...Journal Article -
Radiative asymptotic symmetries of 3D Einstein-Maxwell theory
(2024)SciPost PhysicsWe study the null asymptotic structure of Einstein–Maxwell theory in three-dimensional (3D) spacetimes. Although devoid of bulk gravitational degrees of freedom, the system admits a massless photon and can therefore accommodate electromagnetic radiation. We derive fall-off conditions for the Maxwell field that contain both Coulombic and radiative modes with non-vanishing news. The latter produces non-integrability and fluxes in the ...Journal Article -
Coadaptation of coexisting plants enhances productivity in an agricultural system
(2024)Proceedings of the National Academy of Sciences of the United States of AmericaGrowing crops in more diverse crop systems (i.e., intercropping) is one way to produce food more sustainably. Even though intercropping, compared to average monocultures, is generally more productive, the full yield potential of intercropping might not yet have been achieved as modern crop cultivars are bred to be grown in monoculture. Breeding plants for more familiarity in mixtures, i.e., plants that are adapted to more diverse communities ...Journal Article -
