- WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, saw first light in late 2022. WEAVE comprises a new 2-deg field-of-view prime-focus corrector system, a nearly 1000-multiplex fibre positioner, 20 individually deployable 'mini' integral field units (IFUs), and a single large IFU. These fibre systems feed a dual-beam spectrograph covering the wavelength range 366-959nm at R similar to 5000, or two shorter ranges at . After summarizing the design and implementation of WEAVE and its data systems, we present the organization, science drivers, and design of a five- to seven-year programme of eight individual surveys to: (i) study our Galaxy's origins by completing Gaia's phase-space information, providing metallicities to its limiting magnitude for similar to 3 million stars and detailed abundances for similar to 1.5 million brighter field and open-cluster stars; (ii) survey similar to 0.4 million Galactic-plane OBA stars, young stellar objects, and nearby gas to understand the evolution of young stars and their environments; (iii) perform an extensive spectral survey of white dwarfs; (iv) survey similar to 400 neutral-hydrogen-selected galaxies with the IFUs; (v) study properties and kinematics of stellar populations and ionized gas in z < 0.5 cluster galaxies; (vi) survey stellar populations and kinematics in field galaxies at 0.3 less than or similar to z less than or similar to 0.7; (vii) study the cosmic evolution of accretion and star formation using >1 million spectra of LOFAR-selected radio sources; and (viii) trace structures using intergalactic/circumgalactic gas at z > 2. Finally, we describe the WEAVE Operational Rehearsals using the WEAVE Simulator.

- Multiple sclerosis (MS) often leads to different levels of severity and progression of impairment and disability and to dissimilar levels of limitation in activities and participation in different social domains, with varying impacts on quality of life (QoL) among people with MS (PwMS). Results have shown that, for PwMS, prioritizing goal setting may enhance adherence to treatment. Interdisciplinary rehabilitation may prolong the functional status level of PwMS, may result in transient improvement in the aspects of impairment features, may increase their participation in activities, and may improve their QoL, even when disease progression is not modified. Single rehabilitation packages of comprehensive care have proven beneficial, such as physiotherapy, which enhances aerobic capacity, strength, pain, mood, mobility, and QoL. Occupational therapy can help reduce the impact of impairment on QoL, especially fatigue. Neuropsychological interventions, such as learning and memory remediation, psychological intervention for depressive disorders, and acquistion of coping skills and self-management techniques help PwMS to adjust to disease and disability. Speech therapy can improve intelligibility of communication. Learning swallowing techniques can help prevent material from entering the airway. Clean intermittent self-catheterization can help prevent urinary tract infections. Power wheelchairs enhance occupational performance and energy conservation. Further vocational rehabilitation settings and research are required for more appropriate interventions due to high unemployment rates among PwMS. Comprehensive care for PwMS should include planning for future independent living and long-term care needs.
