Long-term neurostructural and psychological effects of war stress in two generations of civilians from the former Yugoslavia
Abstract The long-term neurobiological and psychological effects of war-related stress on civilians remain understudied. This study focuses on survivors of the war in the former Yugoslavia (G1) who now reside in the Czech Republic and on the children of survivors (G2) who were born after the conflict. Participants from G1, G2, and a control group (CG) with no war experience underwent structural MRI, answered a semi-structured interview, and completed psychological questionnaires (PTGI, PCL-5, SWSL, MSPSS, Brief-COPE). Voxel-based morphometry was used to assess brain volume differences. Compared to CG, G1 showed reduced grey matter volume in regions associated with PTSD and autobiographical memory, including Crus II, parahippocampal gyrus, middle temporal gyrus, and fusiform gyrus. Psychologically, G1 reported higher PTSD symptoms, lower life satisfaction, and greater post-traumatic growth. G2 showed no structural brain changes but scored higher on post-traumatic growth than CG, with no significant differences in other psychological measures. The findings suggest long-lasting neuroanatomical and psychological effects of war stress in directly exposed individuals (G1). Although G2 showed no brain alterations, the increased post-traumatic growth may indicate subtle adaptation effects of growing up in a post-war environment, but not necessarily only in a maladaptive sense.

Impact of processing parameters on the interfacial bonding and properties of recycled LCS/WC–Co bilayers developed through powder metallurgy
Abstract This study aims to develop a tough-hard (LCS/WC-Co) bilayer composite using recycled low-carbon steel (LCS) with WC–Co through conventional powder metallurgy (PM), offering a cost-effective and sustainable route to enhance mechanical performance. Processing parameters like sintering temperature, compaction pressure, and particle size, were optimized to control microstructural development and mechanical behavior. The microstructure results show that the defect-free interfaces, dense layer and strong interfacial bonding strength are achieved at the optimal parameters of 1300 °C, 313 MPa, and 25 μm particle size. Lower sintering temperatures (< 1280 °C) produced porosity and weak adhesion, whereas sintering above 1320 °C led to interfacial cracking. At the interface, mutual diffusion occurred with Fe diffusion into WC–Co and Co migrating into LCS. Concurrently, WC decomposition facilitated the formation of Fe(W) and CoFe intermetallic, together with minor Co₃W₃C and Fe₃W₃C phases. These interfacial reactions provided strong cohesion and enhanced mechanical performance, yielding compressive and tensile interfacial bonding strength of 209 MPa and 44 MPa, with hardness of 150 ± 6 HV for the LCS layer and 660 ± 70 HV for the WC–Co layer.

A novel momentum-based intervention sustains real-life participation in a social movement
Abstract Social protests can play a crucial role in shaping a nation’s direction. But what drives people to stay dedicated to a cause over time? This study was the first to implement a psychological intervention tournament ( N = 1218) within the context of an ongoing social movement, testing the effectiveness of three psychological interventions in promoting sustained engagement in the pro-democracy protests in Israel in 2023, when citizens rallied against a proposed legal reform that threatened to weaken democracy. Our findings revealed that a momentum-based intervention effectively kept participants involved in the movement two and a half months post-exposure, outperforming morality-based and identity-based interventions. These results provide novel and valuable insights for sustaining social protests in pursuit of societal change.
