Abstract:
Abstract The influence of a large-scale circulation (LSC) in a marginal sea on a hysteresis western boundary current (WBC) flowing across a gap is studied using a nonlinear 1.5-layer ocean model. Results show that both single-gyre LSC and double-gyre LSC are able to induce the critical-state WBC transition from the eddy-shedding regime to the leaping regime, while only double-gyre LSC is able to induce the critical-state WBC transition from the leaping regime to the eddy-shedding regime. The dynamics of WBC transition suggests that the meridional advection enhanced by the perturbation of the L

Abstract:
We study the giant component problem slightly above the critical regime for percolation on Poissonian random graphs in the scale-free regime, where the vertex weights and degrees have a diverging second moment. Critical percolation on scale-free random graphs has been observed to have incredibly subtle features that are markedly different compared to those in random graphs with a converging second moment. In particular, the critical window for percolation depends sensitively on whether we consider single- or multi-edge versions of the Poissonian random graph. In this paper, and together with o

Meanwhile, the electrode spacing, temperature, and magnetic field dependence of the two critical voltages are demonstrated experimentally. In particular, we propose that the effective trap-filling process is irreversible under electric field. It is observed

Abstract:
Abstract Stably stratified shear-driven turbulence is analyzed using the gradient Richardson number, Ri, as the stability parameter. The method overcomes the statistical problems associated with the widely used Monin–Obukhov stability parameter. The results of the Ri-based scaling confirm the presence of three regimes: the weakly and the very stable regimes and the transition in between them. In the weakly stable regime, fluxes scale in proportion with variance, while in the very stable regime, stress and scalar fluxes behave differently. At large Ri, the velocity field becomes highly anisotro

Weakly correlated electrons on a square lattice are studied by angle-resolved functional renormalization group. Upon renormalization the interaction starts to depend on monienta and has pole-like solutions near the doping-dependent critical scale. Near half-filling this critical scale is the pseudogap temperature T*. In the overdoped regime the critical scale is the mean-field like critical temperature for d-wave superconductivity.

AbstractOceanic large- and meso-scale flows are nearly balanced in forces between Earth’s rotation and density stratification effects (i.e. geostrophic, hydrostatic balance associated with small Rossby and Froude numbers). In this regime advective cross-scale interactions mostly drive energy toward larger scales (i.e. inverse cascade). However, viscous energy dissipation occurs at small scales. So how does the energy reservoir at larger scales leak toward small-scale dissipation to arrive at climate equilibrium?

It is however recognised that flow regimes affect scale precipitation. Surface growth is influenced by mass transport and diffusion which are susceptible to shear stress and turbulence. Little work has been reported which examine these factors under conditions that can be readily tuned to match field production conditions. Scale inhibitor evaluation exercises therefore often r

Abstract:
Three different experimental configurations to measure oilwater interfacial tension (IFT) are developed using micropipet manipulation technique. By applying the minimum suction pressure required for the interface to flow in a micro-size pipet, IFT is calculated using Young-Laplace equation by achieving mechanical equilibrium condition for the two liquids separated by an interface. The three different configurations produced similar results for critical pressure measurements versus pipet diameter. IFT measurements using micropipet technique found to fall within two regimes: geometry-dependent r

Full text
Abstract:
The pore scale progression of the sublimation front during primary freeze drying depends on the local vapor transport and the local heat transfer as well. If the pore space is size distributed, vapor and heat transfer may spatially vary. Beyond that, the pore size distribution can substantially affect the physics of the transport mechanisms if they occur in a transitional regime. Exemplarily, if the critical mean free path is locally exceeded, the vapor transport regime passes from viscous flow to Knudsen diffusion. At the same time, the heat transfer is affected by the local ratio of pore spa

Abstract:
Abstract Mineral scale formation causes billions of dollars’ loss every year due to production losses and facility damages in the oil and gas industry. Accurate predictions of when, where, how much, and how fast scale will deposit in the production system and how much scale inhibitor is needed are critical for scale management. Unfortunately, there is not a sophisticated scale deposition model available, potentially due to the challenges below. First, an accurate thermodynamic model is not widely available to predict scale potential at extensive ranges of temperature, pressure, and brine compo

The use of Large Eddy Simulation (LES) is computationally intensive and various studies demonstrated the considerable range of vortex scales to be resolved in an LES type of simulation. The purpose of this study is to investigate the use of a Dynamic Grid Adaptation (DGA) algorithm. Despite many developments related to adaptive methods and adaptive grid strategies, the use of DGA in the context of turbulence modelling is still not well understood, and various profound problems with DGA in relation to turbulence modelling are still present.

Full text
Abstract:
Causality and Predictability of Complex Systems pose fundamental challenges even under well-defined structural stochastic-dynamic conditions where the laws of motion and system symmetries are known. However, the edifice of complexity can be profoundly transformed by structural-functional coevolution and non-recurrent elusive mechanisms changing the very same invariants of motion that had been taken for granted. This leads to recurrence collapse and memory loss, precluding the ability of traditional stochastic-dynamic and information-theoretic metrics to provide reliable information about the n

Abstract:
Financial inclusion – where individuals and businesses have access to useful and affordable financial products and services that meet their needs, delivered in a responsible and sustainable way – is a critical component of economic development. It is particularly important in sub-Saharan Africa (SSA), where there can be little traditional banking infrastructure. The success of M-PESA in Kenya shows that mobile money is helping financial inclusion in the region. Those in rural or underserved areas can use mobile money to access basic financial services – savings, payments, and credit – through

Abstract:
Significant investments are needed to support the global transition to a low-carbon, climate resilient future. Current finance flows fall short of global financing needs, and massive scaling up is needed to unlock additional financial resources and foster a sustainable investment pathway. Overcoming barriers to private sector investments is critical, and international climate finance can play a catalytic role in this regard. National development banks (NDBs) have a unique role in this context, both complementing and catalyzing private sector players. NDBs have a privileged position in their lo

Abstract:
Strengthening land governance is critically needed in Latin America and the Caribbean to protect the environment, achieve gender equality in land rights, expand the transparency of land records, and facilitate planned urban growth. Inadequate land administration limits the development of housing markets, tax collection, and the scale and speed of housing and land regularization programs in low-income communities. The region faces major challenges in land tenure informality and overlapping mandates for titling, mapping, and registration. In response to these issues, this technical note identifi

Abstract: High-dimensional learning models exhibit phase transitions, where small changes in model complexity, data size, or optimization dynamics lead to abrupt shifts in generalization, efficiency, and computational feasibility. Understanding these transitions is crucial for scaling modern machine learning algorithms and identifying critical thresholds in optimization and generalization performance.
