Abstract In this paper, we study the effect of different types technological regime changes on evolution industry concentration and wage inequality. Using a calibrated agent-based macroeconomic framework, Eurace@Unibi model, consider scenarios where new is characterized by finite time period more frequent respectively substantial in frontier technology compared to old regime. We show that under...

Return migration is critical to regional endogeneity, especially in rural areas. In recent years, short videos, such as those on TikTok, have become very popular China, which has attracted many people return their hometowns and cyber-celebrities, profiting from the production of videos showcase local agricultural culture. The question focused this paper what extent popularity influenced role it...

In this paper, we propose a symbolic-numeric algorithm to count the number of solutions zero-dimensional square polynomial system within local region. We show that succeeds under condition region is sufficiently small and well-isolating for k-fold solution z system. our analysis, derive bound on size guarantees success. further argue depends parameters such as norm multiplicity well distances b...

This scientific article has the principal goal to demonstrate significance of settlement and mediation in litigious procedure that involve tenant relationship, show influences World pandemic successive treaty, rent contracts theory unpredictability. To reach goals we searched juridical concept about referred institutes, jurisprudence themes, law projects legislation effect. The 2020 year indeed...

The solar radiation absorbed by the photovoltaic thermal systems and not transformed into electricity creates a problem that significantly influences reliability efficiency of cells. In order to passively solve this in hot arid climate, night radiative cooling technology was proposed work, where water system cooled circulating collector exploiting technique, it used next day for For aim, mathem...

This paper reviews the state of art in traffic signal control methods that are based on data coming from onboard smartphones or connected vehicles. The review is carried out by applying analytical scientometric tools (topic visualization, co-citation analysis to establish influential journals and references, country coauthorship, trending-topics overlay visualization). introduction autonomous v...

Environmental cost refers to the paid by enterprises reduce environmental pollution and resource depletion in production operation. To help costs, a manufacturing control algorithm based on machine learning is proposed. The probabilistic neural network used classify current level of different enterprises. Then, particle swarm optimization (PSO) improved build multi-objective backbone PSO for de...

Abstract From ancient times to the present, rising powers have taken up arms reorder world. Yet such violent revisionism poses a puzzle: If power is profiting from existing order, why would it disrupt that progress with reckless fit of expansion? One reason slowing economic growth. Over past 150 years, peaking powers, meaning whose booms slowed but not yet stopped, been most dangerous kind coun...

• Photoluminescent polymer optical fibers (PL-POFs) open new application fields. Equations determining the efficiency of PL-POFs are discussed. Recent advances in several PL-POF related applications reviewed. Methods reported for production described. Polymer (POFs) have been utilized since late 1950s. Adding photoluminescence (PL) to fiber considerably widens functionality POFs and opens In re...
