We consider general locally interacting arbitrary-dimensional lattice spin systems that are gapped for any system size. We show under reasonable conditions that nondegenerate ground states of such systems obey the entanglement area law. In so doing, we offer an intuitive picture on how a spectral gap restricts the correlations that a ground state can accommodate and leads to such a special feature.

Entangled Illnesses: Embodied Experiences of Managing Multimorbidity.

Multimorbidity, meaning multiple long-term conditions impacting a person's health, has become a rising societal and public health issue. The article contributes to the sociological study of chronic illness and multimorbidity by analysing how the blurriness of illnesses and entanglement of symptoms in multimorbidity is experienced and negotiated by people with coexisting chronic conditions. Drawing on qualitative interviews with people who live with endometriosis, fibromyalgia or hormonal migraine in Finland, we show how people with multiple chronic conditions distinguish between evolving symptoms based on past embodied experiences to make decisions about how to best manage their health.

This article examines leisure time physical activity (LTPA) for middle-class women as relational, intricately linked with societal understandings of personal responsibility to work, to family and to health and entangled with the emotion management of 'successful' middle-class womanhood. We focus on middle-class Danish women who engage in routinised participation in LTPA. We illuminate through our qualitative study how emotional reflexivity involves dispersed practices that are entangled with this lifelong physical activity and how these entangled, mutually evolving practices enable women to dutifully enact 'successful' womanhood, in line with contemporary ideals.

Fencing is one of the most widely utilized tools for reducing human-wildlife conflict in agricultural landscapes. However, the increasing global footprint of fencing exceeds millions of kilometers and has unintended consequences for wildlife, including habitat fragmentation, movement restriction, entanglement, and mortality. Here, we present a novel and quantitative approach to prioritize fence removal within historic migratory pathways of white-bearded wildebeest (Connochaetes taurinus) across Kenya's Greater Masai Mara Ecosystem.

Satellite-based quantum communication channels are important for ultra-long distances. Given the short duration of a satellite pass, it can be challenging to efficiently connect multiple users of a city-wide network while the satellite is passing over that area. We propose a network with dual-functionality: during a brief satellite pass, the ground network is configured as a multipoint-to-point topology where all ground nodes establish entanglement with a satellite receiver.

Martin Pugh has drawn attention to the predominantly rural, agricultural support base of the British Union of Fascists. We know that the aspiration to go 'back to the land' was deeply enmeshed with a politics of racial hygiene, which equated the urban with miscegenation and the rural with purity.
