Title: The effects of intracrystalline chain diffusion on the non-linear mechanics of semicrystalline polymers Author(s): Michell, Rose Mary; Petzold, Albrecht; Thurn-Albrecht, Thomas Abstract: Large deformability is a specific property of many semicrystalline polymers that is enabled by plastic flow going along with a restructuring of the semicrystalline morphology in combination with strain hardening caused by network forces. This ability has been linked with the intracrystalline chain diffusion (ICD), which allows chains to move within the crystals. However, the influence of ICD on the non-linear mechanics remains unclear. We here study the intrinsic non-linear mechanical properties of two model polymers, namely PEO with fast ICD and PCL without ICD by mechanical testing in plane strain compression in dependence of strain rates and temperature. For both polymers the stress could be decomposed in an elastoplastic contribution and a network contribution. Strong differences in the true stress-true strain curves became evident by comparing the rate dependence at larger deformation. The stress in PEO depends strongly on rate and temperature, indicating relaxation of the network contribution, while the stress in PCL is rate independent. Experiments for PEO with different molecular weights indicate that the relaxation affects entire chains as expected for ICD.

Title: Pertsch: A Corpus of Persian and German Based on Different Speech Elicitation Tasks Author(s): Mousavi, Neda Abstract: The Pertsch Corpus is a bilingual speech corpus designed to investigate speech production across different communicative situations in Persian and German. The corpus contains recordings from 60 adult speakers (30 Persian, 30 German; balanced for gender), each completing a fixed sequence of seven speech elicitation tasks ranging from controlled read speech to more openended communicative conditions. The elicitation tasks include: • formal read speech • informal read speech • spontaneous conversation • picture description • autobiographical storytelling • informal voice messages • formal voice messages

Title: Root structural and metabolic plasticity confers tolerance to salinity and waterlogging in wild barley species Author(s): Isayenkov, Stanislav; Borisjuk, Ljudmilla; Mayer, Simon; Hilo, Alexander; Knoch, Dominic; Meitzel, Tobias; Hause, Bettina; Tandron Moya, Yudelsy Antonia; Rolletschek, Hardy; Peiter, Edgar; Radchuk, Volodymyr Abstract: Salinity combined with waterlogging is a major abiotic stress that severely limits crop growth and yield. We investigated species-specific adaptations to these stresses in the wild halophytic barleys Hordeum marinum and H. glaucum, compared with the cultivated H. vulgare. Using magnetic resonance imaging, fluorescence scanning microscopy, ¹³C-based carbon fixation analysis, ion and metabolite profiling, we identified key anatomical and physiological traits underlying differential salinity responses. H. marinum exhibited the highest tolerance under saline waterlogging, maintaining water status, metabolic activity and high carbon fixation rates. This species accumulated the lowest concentrations of Na⁺ and Cl⁻ while retaining the highest levels of K⁺ in both roots and shoots. H. glaucum showed intermediate tolerance associated with reduced water content, whereas H. vulgare failed to survive under these conditions. We propose that salinity tolerance in H. marinum is mediated by an integrated root-based mechanism in which intact aerenchyma sustains internal oxygen transport, while salt-induced enhancement of lateral root branching promotes sequestration of excess Na⁺ within the lateral root cortex, thereby limiting its translocation to photosynthetically active tissues. This aeration–sequestration system stabilizes root function under salinity and waterlogging, and promotes whole-plant resilience in wild barleys, but is only weakly maintained in cultivated H. vulgare.

Title: Genetic Parameters for novel behavioral traits for cows housed under automatic milking systems with a focus on learning (Supplementary Table S1) Author(s): Stuhlträger, Julia Abstract: The file provides the complete results of six linear mixed models fitted to behavioral and time‑related traits (RM = rejected milkings, UST = udder scan time, CT = connecting time) recorded by automatic milking systems (AMS). For each response variable, two model versions were computed: one treating the response as a categorical variable (categorized) and one using its continuous values (original). This dual approach allowed us to assess whether the continuous response—despite its non‑normal distribution—yielded model outputs comparable in reliability to those based on the categorized response. The reported LS‑means refer to differences across parities (age) and across levels of AMS experience (learning process).
