Stability of Perovskite Indoor Photovoltaics: A Focused Review and a Call for Standardized Stability Reporting

open access: yesAdvanced Energy Materials, EarlyView.
While perovskite solar cells have been widely studied, including their stability, perovskite indoor photovoltaics (IPVs) have only recently emerged. Nevertheless, more studies are appearing in the literature. The systematic stability study of IPVs is crucial, particularly given the inconsistencies in reported methodologies and results, which call for ...

Development of Hazard Level-based Rainfall Threshold for Prediction of Rainfall-induced Landslide Occurrence in Korea

open access: yesJournal of the Korean Society of Hazard Mitigation, 2019
Landslides are one of the major natural disasters in Korea, and they frequently cause infrastructure damage, property loss, and human casualties. The main cause of landslides is localized rainfall. Therefore, the analysis of landslide-triggering-rainfall

Do the recent severe droughts in the Amazonia have the same period of length? [PDF]

open access: yes, 2015
We propose a new measure based on drought period length to assess the temporal difference between the recent two severe droughts of 2005 and 2010 in the Amazonia.

A Leaf‐Inspired Janus‐Structured Triboelectric‐Moisture Hybrid Energy Harvester

open access: yesAdvanced Energy Materials, EarlyView.
This study proposes a bioinspired Janus structured energy‐leaf with hybrid triboelectric‐moisture hybrid energy harvesters. This hybrid energy harvester is demonstrated in an intelligent emergency system for effective distress signaling and evacuation guiding during potential crises.

Coupling antecedent rainfall for improving the performance of rainfall thresholds for suspended sediment simulation of semiarid catchments

open access: yesScientific Reports, 2022
Suspended sediment transport is one of the essential processes in the geochemical cycle. This study investigated the role of rainfall thresholds in suspended sediment modeling in semiarid catchments. The results showed that rainfall-sediment in the study

Rainfall threshold and soil moisture indexes for the initiation of landslide in Banjarmangu sub-district, central Java, Indonesia

open access: yesIOP Conference Series: Earth and Environment, 2019
Rainfall is an identified trigger of landslides, and researchers have long attempted to ensure the total precipitation that can trigger slope failures under different local climate condition, a problem of scientific interest.

Temperature and Farm Labor in Nigeria

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

Research on the early warning threshold for typhoon rainstorm-induced landslides based on rainfall index: A case study of Yongtai County, Fuzhou

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao
In the southeastern hilly regions of China, extreme rainfall frequently triggers landslide disasters, characterized by their rapid occurrence and clustering.

Global Distribution of Urban Landslide Rainfall Thresholds

open access: yes, 2022
Rainfall-triggered landslides in urban areas cause fatalities and damage globally, but landslide early warning systems operating in individual cities rely on different data sources and methods, making a comparison of thresholds challenging. In this study, we estimate the distribution of intensity-duration (I-D) and event-duration (E-D) rainfall ...

Adapting to Changing Rainfall and Developing Off‐Farm Employment: Implications for the Adoption of Direct Seeding in Rice Production

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Rice is the main staple food for more than half of the world's population and the income from rice is an essential source for livelihoods of millions of households. We examine whether direct seed in rice production is an adaptation of rice farmers to rainfall changes and farm labor scarcity.
