Changes in nutritional status are important in clinical practice because they relate to an increase in morbidity and mortality. Studies about nutritional problems in hospitalized adults have been reported since the 1970s. The prevalence of malnutriti

Hydropower can have significant impacts on riverine ecosystems due to hydropeaking (i.e., artificial rapid and short-term fluctuations in water flow and water levels downstream and upstream of hydropower stations) that negatively affect downstream fi

Mechanical metamaterials with alternating Poisson’s ratios are desirable for shape-morphing applications. Here the authors achieve this by utilizing self-contacting hard stops and flexible elements of different stiffnesses to achieve time-ordered s

The water availability estimation in large regions is a relevant procedure to define broad water resources management policies but may prove difficult due to the lack of data and uncertainty to related regional hydrological and hydrogeological charac

Designing mechanical metamaterials is challenging because of the large number of non-periodic constituent elements. Here, the authors develop an approach to design arbitrarily shaped metamaterials that is more computationally efficient by six orders

Most current methods for additive manufacturing of complex metallic 3D structures are limited to a resolution of 20–50 µm. Here, the authors developed a lithography-based process to produce 3D nanoporous nickel nanolattices with octet geometries a
