Article Abstract
Robotic competitions are an excellent way to promote innovative solutions for the current industries' challenges and entrepreneurial spirit, acquire technical and transversal skills through active teaching, and promote this area to the public. In other words, since robotics is a multidisciplinary field, its competitions address several knowledge topics, especially in the STEM (Science, Technology, Engineering, and Mathematics) category, that are shared among the students and researchers, driving further technology and science. A new competition encompassed in the Portuguese Robotics Open was created according to the Industry 4.0 concept in the production chain. In this competition, RobotAtFactory 4.0, a shop floor, is used to mimic a fully automated industrial logistics warehouse and the challenges it brings. Autonomous Mobile Robots (AMRs) must be used to operate without supervision and perform the tasks that the warehouse requests. There are different types of boxes which dictate their partial and definitive destinations. In this reasoning, AMRs should identify each and transport them to their destinations. This paper describes an approach to the indoor localization system for the competition based on the Extended Kalman Filter (EKF) and ArUco markers. Different innovation methods for the obtained observations were tested and compared in the EKF. A real robot was designed and assembled to act as a test bed for the localization system's validation. Thus, the approach was validated in the real scenario using a factory floor with the official specifications provided by the competition organization.

Parent/caregiver perspectives of meaningful improvement in functional domains for people with CDKL5 deficiency disorder: a mixed-methods study.
Qual Life Res

Purpose: CDKL5 deficiency disorder (CDD) is a rare developmental and epileptic encephalopathy. Greater understanding of the smallest meaningful improvements for individuals with CDD in clinical trials and practice is needed for a person-centred approach to treatment efficacy. This study explored how parent/caregivers of people with CDD understood meaningful improvements and described change for priority functional domains including communication, gross motor, fine motor, feeding.

Vasculature plays a crucial role in tissue engineering since it is essential for maintaining tissue viability by efficient nutrient and oxygen exchange as well as waste removal. The creation of biomimetic vascular networks is therefore critical for the development of functional tissue constructs. Sacrificial biofabrication has emerged as an effective method for engineering vascular structures by creating temporary templates that are subsequently removed to form well-defined vascular channels.

Background: Rapid advances in generative artificial intelligence (AI) are accelerating the process of pesticide development. However, transfer learning-based de novo design focuses on generating molecules that are highly similar to existing inhibitors, which may limit the exploration of novel scaffolds and thereby constrain innovative breakthroughs in pesticide development.
Results: This study proposes a new strategy for fungicide design using antibiotics.
Ambivalent Agents: The Social Mobility Industry and Civil Society Under Neoliberalism in England.

This article examines civil society organisations working to enhance social mobility in England, especially through higher education. Against the backdrop of neoliberal governance, we investigate whether these organisations operate as protective counter-movements resisting marketisation or as institutional mechanisms that stabilise the inequalities they aim to address. Drawing on Karl Polanyi's concept of the 'double movement' and Nancy Fraser's critique of marketised social protections, we map and analyse over 100 charities and non-profits established since 1992.

Rift Valley fever (RVF), a zoonotic mosquito-borne viral disease with erratic occurrence and complex epidemiology, results in substantial costs to veterinary and public health and national economies. Since 1985, RVF virus (RVFV) epidemiology has focused on epidemics triggered by flood-induced emergence of transovarially infected mosquitoes, following an interepidemic period during which RVFV persists primarily in floodwater Aedes spp mosquito eggs, with potential for low-level interepidemic circulation. In this Personal View, we challenge this classic framework of RVFV epidemiology, presenting instead a spectrum of RVFV dynamics ranging from epidemic to hyperendemic.
