Critical barriers and countermeasures to urban regeneration from the stakeholder perspective: a literature review

Urban renewal involves a wide range of stakeholders with diverse expectations and interests. Conflicts in urban renewal projects arise from intricate relationships among multiple stakeholders, hindering the urban renewal process. With a large amount of current literature examining the barriers, difficulties, and solutions in urban regeneration, a critical review is required to holistically summarize these main concerns and challenges from the stakeholder perspective. Based on 347 journal papers collected from the Web of Science core database, this study investigates the development, trajectory, and tendency of prior studies through a bibliometric analysis. Then, a critical review is documented with eight critical barriers in the economic and social aspects from the stakeholder perspective. To address these issues, this study proposes a strategic framework for value creation, collaborative governance, and benefit sharing. Accordingly, future research agendas are also presented. This study could provide researchers with a systematic understanding of the critical barriers and potential strategies in urban regeneration fields

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Asymptotic stability for a viscoelastic equation with the time-varying delay

The goal of the present paper is to study the viscoelastic wave equation with the time-varying delay under initial-boundary value conditions. By using the multiplier method together with some properties of the convex functions, the explicit and general stability results of the total energy are proved under the general assumption on the relaxation function g

Global existence and blow-up of weak solutions for a class of fractional p-Laplacian evolution equations

In this paper, we study the fractional p-Laplacian evolution equation with arbitrary initial energy
