Mapping Kabul’s Private Urban Green Spaces Using Geographic Information System-Supervised Classification

open access: yesJournal of Landscape Ecology, 2020
Private green spaces are considered an important part of urban greenery. However, the extent of private green spaces in an informal city like Kabul is unknown. To this end, this study has mapped out the private green spaces in the informal settlements of

Natural environments and suicide mortality in the Netherlands: a cross-sectional, ecological study [PDF]

open access: yes, 2018
Background: Natural outdoor environments, such as green spaces (ie, grass, forests, or parks), blue spaces (ie, visible bodies of fresh or salt water), and coastal proximity, have been increasingly shown to promote mental health.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Attributes of Urban Greenspaces and their Influence on Visitors’ Preferences in Nairobi City County, Kenya

open access: yesEastern African Journal of Humanities and Social Sciences
Urban green spaces refer to land covered with vegetation such as forests, street trees, parks, gardens, and water bodies in an urban setup. In this study, we sought to investigate the attributes of urban green spaces in Nairobi County and their ...

A spectral radius type formula for approximation numbers of composition operators [PDF]

open access: yes, 2014
For approximation numbers $a_n (C_\phi)$ of composition operators $C_\phi$ on weighted analytic Hilbert spaces, including the Hardy, Bergman and Dirichlet cases, with symbol $\phi$ of uniform norm $< 1$, we prove that $\lim_{n \to \infty} [a_n (C_\phi)]^{

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Planning of urban park green space layout - adopting an optimization model

open access: yesSustainable Buildings
This paper briefly introduces a park green space evaluation model based on supply and demand accessibility, the K-means algorithm for determining the optimal number of new green spaces, and an improved genetic algorithm (GA) for planning these spaces ...

Disaster consequence mitigation and evaluation of roadside green spaces in Nanjing

open access: yesJournal of Environmental Engineering and Landscape Management, 2019
The extensive layout of roadside green spaces make them important green disaster mitigation nodes in high-density areas of any city; hence, further improvements in their disaster mitigation functions would make the urban disaster prevention system more ...

Bioclimatic Urban Green Indicator for the sustainability of cities in arid environment. [PDF]

open access: yes, 2017
Within the sustainability of cities located in arid environments, bioclimatic indicators of urban green are proposed, taking as a study case the Metropolitan Area of San Juan, Argentina, city located in the arid strip of South America, which has one of ...
