Finding conditions that support synchronization is a fertile and active area of research with applications across multiple disciplines. Here we present analyze scheme for synchronizing chaotic dynamical systems by transiently uncoupling them. Specifically, coupled only in fraction their state space may synchronize even if fully they do not. While many standard coupling strengths need to be bounded ensure synchrony, transient removes this bound thus enables an infinite range effective...

Few African countries have reported COVID-19 case numbers above $1\,000$ as of April 18, 2020, with South Africa reporting $3\,034$ cases being hit hardest in Sub-Saharan Africa. Several countries, especially Africa, already taken strong non-pharmaceutical interventions that include physical distancing, restricted economic, educational and leisure activities reduced human mobility options. The required strengths overall effectiveness such interventions, however, are debated because...

Abstract The Global South, encompassing more than 80% of the world population, heavily relies on informal paratransit services with ad-hoc routes. Yet, it remains unclear how efficiently such public transport organize and operate. Here, we analyze compare structural efficiency 7000 formal bus service routes in 36 cities across 22 countries globally. Intriguingly, self-organizes ways at or above levels centralized services. They exhibit fewer detours, uniform paths, comparable...

Ride-sharing may substantially contribute to future-compliant sustainable mobility, both in urban and rural areas. The service quality of ride-sharing fleets jointly depends on the topology underlying street networks, spatio-temporal demand distributions, dispatching algorithms. Yet, efficiency services is typically quantified by economic or ecological ad-hoc measures that do not transfer new regions with different characteristics. Here we derive a generic measure based intrinsic dynamics...

Cycling is crucial for sustainable urban transportation. Promoting cycling critically relies on sufficiently developed infrastructure; however, designing efficient bike path networks constitutes a complex problem that requires balancing multiple constraints. Here we propose framework generating networks, explicitly taking into account cyclists' demand distribution and route choices based safety preferences. By reversing the network formation, iteratively remove paths from an initially...

Ride sharing - the bundling of simultaneous trips several people in one vehicle may help to reduce carbon footprint human mobility. However, standard door-to-door ride services trade reduced route length for increased user travel times and come with burden many stops detours pick up individual users. Requiring some users walk nearby shared reduces detours, but could become inefficient if spatio-temporal demand patterns do not well fit stop locations. Here, we present a simple computational...

We present the finite-size Kuramoto model analytically continued from real to complex variables and analyze its collective dynamics. For strong coupling, synchrony appears through locked states that constitute attractors, as for real-variable system. However, persists in form of coupling strengths K below transition K^{(pl)} classical phase locking.

The adoption of battery electric vehicles (BEVs) may significantly reduce greenhouse gas emissions caused by road transport. However, there is wide disagreement as to how soon will play a major role in overall transportation. Focusing on passenger cars, we analyze BEV across 17 individual countries, Europe, and the World, consistently find exponential growth trends. Modeling-based estimates future given past trends suggest system-wide substantially faster than typical economic analyses have...

Synchronization is the process of achieving identical dynamics among coupled units. If units are different from each other, their cannot become identical; yet, after transients, there may emerge a functional relationship between them—a phenomenon termed “generalized synchronization.” Here, we show that concept transient uncoupling, recently introduced for synchronizing units, also supports generalized synchronization nonidentical chaotic Generalized can be achieved by uncoupling even when it...

We analyze the properties of order parameters measuring synchronization and phase locking in complex oscillator networks. First, we review network previously introduced reveal several shortcomings: none capture all transitions from incoherence over to full synchrony for arbitrary, finite then introduce an alternative, universal parameter that accurately tracks degree partial synchronization, adapting traditional definition account topology its influence on coherence oscillators. rigorously...

Abstract Synchronization constitutes one of the most fundamental collective dynamics across networked systems and often underlies their function. Whether a system may synchronize depends on internal unit as well topology strength interactions. For chaotic units with certain interaction topologies synchronization might be impossible all strengths, meaning that these networks are non-synchronizable. Here we propose concept control , generalizing transient uncoupling, to induce desired in...

Abstract Ride-sharing—the combination of multiple trips into one—may substantially contribute towards sustainable urban mobility. It is most efficient at high demand locations with many similar trip requests. However, here we reveal that people’s willingness to share rides does not follow this trend. Modeling the fundamental incentives underlying individual ride-sharing decisions, find two opposing adoption regimes, one constant and another decreasing as increases. In limit, transition...

Abstract Ride-pooling (or ride-sharing) services combine trips of multiple customers along similar routes into a single vehicle. The collective dynamics the fleet ride-pooling vehicles fundamentally underlies efficiency these services. In simplified models, common features give rise to scaling laws that are valid across wide range street networks and demand settings. However, it is unclear how constraints vehicle impact such laws. Here, we map capacity-constrained fleets with unlimited...

Abstract Ride sharing services combine trips of multiple users in the same vehicle and may provide more sustainable transport than private cars. As mobility demand varies during day, travel times experienced by passengers substantially vary as well, making service quality unreliable. We show through model simulations that such time fluctuations be drastically reduced stop pooling. Having walk to meet at joint locations for pick-up or drop-off allows buses direct routes avoiding frequent...

The Kuramoto model and its generalizations have been broadly employed to characterize mechanistically understand various collective dynamical phenomena, especially the emergence of synchrony among coupled oscillators. Despite almost five decades research, many questions remain open, in particular, for finite-size systems. Here, we generalize recent work [Thümler et al., Phys. Rev. Lett. 130, 187201 (2023)] on with state variables analytically continued complex domain also complexify system...

The emergence of large-scale connectivity underlies the proper functioning many networked systems, ranging from social networks and technological infrastructure to global trade networks. Percolation theory characterizes network formation following stochastic local rules, while optimization models assume a single controlling authority or one objective function. In socioeconomic networks, however, is often driven by individual, locally optimal decisions. How such decisions impact only poorly...

Spreading phenomena on networks are essential for the collective dynamics of various natural and technological systems, from information spreading in gene regulatory to neural circuits or epidemics supply experiencing perturbations. Still, how local disturbances spread across is not yet quantitatively understood. Here we analyze generic deterministic network dynamical systems close a given operating point. Standard systems' theory does explicitly provide measures arrival times amplitudes...
