β‐C(sp3)—H Arylierung Aliphatischer Sulfonamide

Angewandte Chemie, EarlyView.
Das erste Protokoll zur β‐C(sp3)—H‐Aktivierung/Funktionalisierung aliphatischer Sulfonamide wird beschrieben. Die Arylierung solcher Substrate wird durch den Einsatz von N‐Acetylthioether‐Liganden ermöglicht und zeichnet sich durch ein breites Substratspektrum sowohl hinsichtlich des Sulfonamid‐Substrats als auch des Arylierungsreagenzes aus.

Post With Care: How Language Use Influences the Effectiveness of CEOs' Climate‐Related Messages on Social Media

Business Strategy and the Environment, EarlyView.
ABSTRACT Chief executive officers (CEOs) play a pivotal role in shaping public discourse on climate change through social media, yet how their language use affects the effectiveness of climate‐related posts remains unclear. Drawing on schema‐congruity theory and leader role expectations, we conceptualize certainty in language as congruent and anxiety ...

Salinity Indian Ocean Dipole: Another facet of the Indian Ocean Dipole phenomenon from satellite remote sensing

Science of Remote Sensing
Using satellite-measured sea surface salinity (SSS) from the Aquarius and Soil Moisture Active Passive (SMAP) missions since 2011, we show that SSS in the Equatorial Indian Ocean (EIO) experienced dipolar changes in the well-defined east EIO and west EIO

Using a DAP to fit an increasing IoD range.

, 2019
Noise or variability in the spike rate is measured using the IoD. The presence of a large AHP results in a decreasing IoD range, where variability is less at larger binwidths [21]. An increasing IoD range can be mimicked either by a highly variable input

Impact of different El Niño types on the El Niño/IOD relationship [PDF]

, 2015
Previous studies reported that positive phases of the Indian Ocean Dipole (IOD) tend to accompany El Niño during boreal autumn. Here we show that the El Niño/IOD relationship can be better understood when considering the two different El Niño flavors ...

Compound Meteorological and Hydrological Hot‐Dry and Hot‐Wet Extremes Over Global Land Areas: Spatiotemporal Changes, Attribution, and Drivers

International Journal of Climatology, EarlyView.
The changes in joint return period of compound meteorological hot‐dry (CMHHE) and hot‐wet (CMHWE) and compound hydrological hot‐dry (CHHDE) and hot‐wet (CHHWE) extremes were attributed to changes in associated univariate extremes and their dependence.
