Sustainable urban growth patterns based on environmental fitness
Frontiers in Sustainable CitiesThis study examines the sustainability of urban growth, described by patterns of environmental fitness. The main assumption is that resource use—energy, materials, electricity, water, fossil fuels, soil, and humans—describes growth patterns whose ...

Advanced Science, EarlyView.Herein, we propose a solar‐powered heavy metal trap (SPHT) for sludge disposal. The indoor experiments demonstrated that the sludge water content decreased from 90 % to 31 %, coupled with a decrease in heavy metal content to 6 % at most. Furthermore, the designed SPHT generated an initial potential of 0.10 V, and monitoring this hydrovoltaic potential ...

Dimensions of Urban Growth in Pakistan [PDF]
The Pakistan Development Review, 1991 The urban population of Pakistan has grown almost fourfold, over the last two decades. It is estimated that it will increase by 55.5 million by the year 2000 [Blacker (n.d.)]. The increases in urban population is attributed to either continued rural to urban migration or natural increase.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems
Advanced Electronic Materials, EarlyView.Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Estimates of reductions in greenhouse gas (GHG) emissions from lower demand for cattle‐based products must account for substitution effects. This study collected data through two surveys—one on ground beef and another on dairy milk—to evaluate substitution effects and potential GHG reductions.

On the Economics of US Agricultural Policy
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This paper presents an economic analysis of US agricultural policy, building on a modified version of Gardner's efficient redistribution. We argue that agricultural policy is motivated as an attempt to implement an efficient redistribution scheme that redistributes income toward farmers who, as a group, have been adversely affected by ...

Morbidity Among the Aging Population in Northern Bangladesh: An Epidemiological Study
AGING MEDICINE, EarlyView.Multimorbidity (≥ 2 chronic diseases) is common among aging populations, yet evidence from Bangladesh remains limited. A cross‐sectional survey of 540 older adults in Northern Bangladesh (June–August 2022) assessed multimorbidity using interviews and logistic regression analysis. Multimorbidity prevalence was 75.74% (95% CI: 71.9%–79.3%).

Ecosystem service of green infrastructure for adaptation to urban growth: function and configuration
Ecosystem Health and Sustainability, 2018 Objectives: (1) to explore what kind of green infrastructure (GI) meets the demand for urban ecological security of rapid urbanization areas; (2) to figure out how to determine the specific function and configuration of GI from ecosystem service ...
