Meromorphic differentials and twisted DR hierarchies for the Hodge CohFT

Abstract In [4], two families of classical and quantum integrable hierarchies associated to arbitrary Cohomological Field Theories (CohFTs) were introduced: the meromorphic differential and twisted double ramification hierarchies. For trivial CohFT, the authors established a conn...

Stability Analysis of Nonseparable Mean-Field Games for Pedestrian Flow in Large Corridors

Abstract. We investigate the existence and stability of small perturbations of constant states of the generalized Hughes (GH) model for pedestrian flow in an infinitely large corridor. We show that constant flows are stable under a condition on the density. Our findings indicate...

A dual-LSTM model for CLV distributions: Diverging paths and bimodalities

Abstract Virtually all customer lifetime value (CLV) models reduce the future of a customer to a single number, its expected value, implicitly assuming managers are indifferent to how that value materializes. Yet in a survey of management consultants from a leading global strateg...

Design-guided synthesis of customizable carbonized electrodes for maximizing charge storage in carbon-based supercapacitors

3D carbon foams, CarboHIPEs, were successfully developed as self-standing electrodes for supercapacitor applications through the sulfonation and pyrolysis of polymerized High Internal Phase Emulsions. The fabrication process was systematically optimized by investigating the influ...

Evaluation of Varnishes to Slow Down the Aging of Plasticized PVC

ABSTRACT This study investigates the preventive and curative potential of surface varnishes to mitigate the aging of plasticized PVC (p‐PVC), with particular emphasis on the influence of the PVC formulation on coating efficiency. Two industrial p‐PVC formulations were studied: PV...

Comparative study on properties of self-compacting rubberized concrete incorporating demolition and waste clay brick aggregates

The combined use of demolition brick aggregate (DBA) and discarded clay brick (CBA) with crumb rubber (CR) in a single concrete mixture remains largely unexplored. This study investigates the use of these two types of brick aggregate waste and their combined effect on the propert...

Autonomous Vehicles, Urban Deployment, and Welfare Effects

ABSTRACT This paper provides a theoretical analysis of the effects of autonomous vehicles (AVs) on the spatial structures of future cities. We consider two types of AVs, private AVs (PAVs) and shared AVs (SAVs). We assume that AVs have a lower marginal travel time cost than human...

Synergic effect of waste brick powder, waste ceramic powder and marble powder on rheological behaviour, mechanical behaviour and carbon footprint of binary and ternary mortars

Although waste brick powder (WBP), waste ceramic powder (WCP), and marble powder (MP) have been individually investigated as cement substitutes, their combined effects on rheological behaviour, mechanical performance, and strength-normalised environmental efficiency remain insuff...

Three-colour pride—geometry and topological transformations in self-assembly models of three-arm star molecules

Abstract Polyphilic three-arm star-shaped molecules self-assemble in a wide variety of morphologies. We present an analysis of the geometry of the possible mesophases formed by three-star molecules with mutually immiscible arms. The structures resulting from such molecular self-a...

Experimental Investigation of Thermal and Mechanical Properties of Sorghum Stalk Fiber-Reinforced Cement Mortar for Thermal Insulation: Influence of Length, Percentage of Fibers and Water to Cement Ratio

Sustainable building materials development is essential for improving energy efficiency, addressing environmental concerns and optimizing resources use. This study investigates the development and characterization of sorghum stalk fiber-reinforced cement mortar bio-composite for...

Altered excitation-inhibition balance in the somatomotor and default mode network in multiple sclerosis

Excitation-Inhibition (E/I) balance is a system-level principle governing healthy neuronal information processing. Its disruption has been implicated in the pathophysiology of multiple sclerosis (MS), yet in vivo characterization of E/I balance in MS remains under debate. In MS,...

Chemical desorption of methanol induced by hydrogen abstraction–addition cycles on cold grain surfaces

Abstract We report ultra-high vacuum experiments on the non-thermal desorption of methanol (CH3OH) from cold dust-grain analogues under hydrogen-atom bombardment. Monolayer methanol films on polycrystalline gold, compact amorphous solid water (ASW, 10 ML) and 13CO ice (2 ML) are...
