Summary: This study identified a mechanism of thromboprotection in immobilized brown bears and spinal cord injury patients, involving the down-regulation of heat shock protein 47 (HSP47) in platelets. This resulted in attenuated immune cell activation and neutrophil extracellular trap formation, providing potential therapeutic targets for antithrombotic treatments.

Summary: In this research, observations through three lidars are used to study the wave structures in the atmosphere. Results show the occurrence of a peculiar sodium layer structure with a large horizontal scale over 310 km, which was formed in an extremely stable atmosphere. The occurrence of this structure is closely related to the propagation and breaking of gravity waves.

Summary: A new distance protection algorithm using LSP to estimate frequency and fault distance is proposed to enhance the protection performance of MTDC systems. The algorithm utilizes only local measurements without the need for communication, demonstrating its effectiveness in simulation and real-time testing.

Summary: Analysis of the variation of potential gradient at ground level is important in monitoring the global electric circuit and its interactions with solar and geophysical phenomena. This study conducted spectral analysis of potential gradient recorded at several sites in both the Northern and Southern Hemisphere. The results revealed various periodicities and their relationships with solar rotation and Madden-Julian Oscillation. The findings contribute to a better understanding of the global electric circuit.

Summary: The availability of hard mast and soft-mast producing species is influenced by forest typology, historical forestry practices, and topographical features. Herb cover is negatively affected by terrain steepness and basal area, while ant richness is associated with forest volume and density. These findings provide valuable information for forest management practices to support the conservation of Apennine bears in the long term.

Summary: Natural habitats are being degraded and fragmented due to human expansion, threatening the survival of many species. Understanding species distribution and identifying movement corridors is crucial for conservation. Serbia's geographical position plays a significant role in connecting bear metapopulations. The study predicts suitable habitats and proposes measures for habitat permeability to benefit not only bears but also other species in the region.

Summary: Suspended sediment concentration (SSC) is an important indicator for coastal health and geomorphological evolution. Remote sensing data can be used to estimate SSC, but extracting the amplitude and phase of SSC on multiple timescales is challenging. In this study, a 9-year GOCI SSC time series from two coastal sites in China was used to investigate the extraction of amplitude and phase from satellites with different temporal resolutions. The results showed that lower temporal resolutions led to increased amplitude and phase deviations on seasonal and fortnightly timescales. However, combining data from multiple satellites reduced the errors.

Summary: An assessment of the genetic diversity and structure of two endangered brown bear populations in Italy was conducted to propose a cost-effective management protocol for populations with low genetic variation. By analyzing microsatellite loci, the study identified the most effective STR marker sets for evaluating genetic diversity and individual discrimination. The findings indicate that the Uam population should be considered a conservation priority due to its depleted genetic variability.

Summary: A captive female Eurasian brown bear in her 24th year of age gave birth to a stillborn cub with multiple malformations resulting from anomalous neural tube development. These malformations, including anencephaly, hypoplasia, micromyelia, severe myelodysplasia, syringomyelia, and spina bifida, have not been previously reported in bears. The cause of the malformations remains unknown, but the mother's advanced age and/or folic acid deficiency may be possible factors. Supplementing the mother with folate before and during early pregnancy could help prevent the occurrence of neural tube defects in captive bears, thus safeguarding the future generations of this endangered species.

Summary: The latest IPCC assessment report suggests that natural climate variability can temporarily strengthen or mask anthropogenic climate change over a period of ten years. Global mean surface temperatures have been analyzed, revealing two main oscillations - a strong oscillation with a period of about 70 years and an amplitude of about 0.09K, and a quasi-bidecadal oscillation with an amplitude of about 0.06K. The strong oscillation exhibits significant hemispheric differences and can either enhance or weaken the overall increase in temperature.

Summary: This study investigates the temporal variation of the approximate 27-day and Rieger periodicities in the spectral emission of Fe XIV solar corona observed at 530.3 nm from January 1, 1940 to December 31, 2008. The results show significant power in both periodicities with annual variations. It is found that the power of the Rieger periodicity exceeds that of the approximate 27-day period during solar maximum.

Summary: The double-beta decays of Mo-100, originating from a high-purity sample with a 6.0195-year exposure, were studied by the NEMO-3 experiment. These ultra-rare transitions to Ru-100 have a half-life of approximately 7 x 10(18) years and were used to search for periodic variations in the decay mode. Analysis using the Lomb-Scargle periodogram technique showed no evidence of modulations in the half-life with an amplitude greater than 2.5% in the studied frequency range.

Summary: Humans can significantly alter the temporal activity of wildlife, and the ecological consequences of such shifts can lead to reduced fitness, increased competition, and trophic cascades. This study examined the potential of human disturbance as a temporal-shield for brown bears foraging on sockeye salmon in southwestern Alaska. The results showed that all bears avoided peak times of human activity, but socially-subordinate subadult bears had higher overlap with humans compared to females with cubs and single adults. The findings suggest that human-disturbance can have complex effects on large carnivores and may provide increased foraging opportunities for socially subordinate, but more human-tolerant individuals.
