Summary: The mass and angle distributions for the Cr-52 + Pt-198 and Cr-54 + (19)6Pt reactions forming No-250 were measured and subtracted. The experimental mass distributions unexpectedly extended to symmetric splits, while the peak yield remained close to the initial masses, indicating a strong role of fluctuations in mass division early in the collision. This provides insights into the transition from fast energy dissipative deep-inelastic collisions to quasifission.

Summary: Charged droplets, suspended in an electrodynamic balance, undergo Coulombic fission during evaporation. This study observed up to 15 Coulombic fissions in a single droplet, with each fission releasing approximately 14% of the droplet's charge. It was found that droplets with similar initial relative charge sustain fissions at similar normalized diameters, independent of initial droplet size and evaporation rate. Based on the d2-law of pure-fluid droplet evaporation, the times at which Coulombic fissions occur can be predicted for a given initial droplet size and evaporation rate.

Summary: This study investigates the influence of aggregation patterns on the generation of reactive oxygen species (ROS) by organic photosensitizers (PSs). It is found that the S-2TPA-2PI-aggregate, which forms end-to-end stacking through pi-pi interaction, can efficiently generate ROS. This finding not only reveals the structure-property relationship of organic PSs but also provides insights for the development of future photodynamic therapy and photocatalysis.

Summary: In recent years, 3-D scanning data have become increasingly important in precision livestock farming. This study proposes a robust livestock pose normalization method based on 2-D/3-D fusion, which utilizes 2-D information to accurately determine the orientation of livestock in 3-D and improves segmentation by generating frustums in 3-D space. Extensive experiments show that the proposed method is more robust and practical than existing methods.

Summary: We conducted a systematic study on the widths of fission fragment mass distributions in compound nucleus fission in the pre-actinide region. We analyzed different reaction variables, such as mass asymmetry, ZPZT, N/Z ratio, and excitation energy. The results indicate non-equilibrated fission process or mass asymmetric fission in cases where the mass width shows anomalous behavior with fissioning nuclei excitation energy. The study demonstrates the systematic dependence of the reaction mechanism on entrance channel parameters.

Summary: Singlet fission (SF), the process of generating two triplet excitons from one singlet exciton, has the potential to improve the efficiency of single-junction solar cells. Accurate identification and quantification of SF and differentiation from intersystem crossing (ISC) are crucial. In this study, the upper bound of ISC rate in two commonly studied SF chromophores, TIPS-pentacene and TIPS-tetracene, is quantified using transient absorption spectroscopy. The results show that previous misidentification of SF as ISC and vice versa has occurred, emphasizing the importance of accurate quantification of ISC.

Summary: Evidence from models and experiments suggests that the networked structure observed in mitochondria emerges at the critical point of a phase transition controlled by fission and fusion rates. In this study, we provide a theoretical framework to interpret the scaling behavior of mitochondrial network quantities and validate it through experiments. The obtained scaling exponents are comparable with critical exponents from models and theory. Overall, we offer a universal description of the structural phase transition in mammalian mitochondria.

Summary: In this article, a new algorithm based on 2D-3D mutual projections is proposed for region growing, successfully dividing visible points and occlusion points, and achieving satisfactory results in intensity fusion. The method is more robust for large curvature change and large density change regions, and outperforms existing methods in accuracy for car models.

Summary: Singlet fission materials have the potential to overcome traditional efficiency limits of OLEDs, with 55BT showing efficient SF in a locally excited singlet state. Its covalent bonding of tetracene units makes it a promising triplet sensitizer for near-infrared OLEDs, compared to other SF systems like the tetracene dimer.

Summary: Fragmentation of mitochondria due to defective fusion or unopposed fission contributes to neurodegenerative diseases. Rational redesign based on pharmacophores generated a novel class of mitofusin activators, with analogue 5 incorporating a cycloalkyl linker group showing improved pharmacokinetic properties. Stereoisomeric studies revealed that the biological activity of analogue 5 resides in the trans-R/R configuration, 5B, which may have potential therapeutic implications for neurological conditions.

Summary: Cerebral ischemia and reperfusion injury can lead to poor oxygen supply, brain infarction, and an imbalance in mitochondrial dynamics, which plays a crucial role in cell survival and infarct area size regulation. Understanding and regulating mitochondrial dynamics may help prevent or treat cerebral injury.

Summary: Alterations in mitochondrial function and morphology are critical adaptations to cardiovascular stress, working in concert in an attempt to restore organelle-level and cellular-level homeostasis. Processes that alter mitochondrial morphology include fission, fusion, mitophagy, and biogenesis, and these interact to maintain mitochondrial quality control. Both pathological stressors like ischemia and physiological stressors like aerobic exercise can induce morphologic adaptations in mitochondria, but with different outcomes for mitochondrial health. Understanding the mechanisms underlying alterations in mitochondrial quality control under diverse cardiovascular stressors can aid in developing pharmacologic interventions for restoring cellular homeostasis.
