Borylcyclopropanes: Synthetic Strategies and Applications

Angewandte Chemie, EarlyView.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

The Analysis of the Influencing Factors on the Problems of Bike-Sharing System in China

IEEE Access, 2019
Bike-sharing has experienced rapid growth in China since 2016. Notwithstanding the fast expansion, or possibly because it grew too fast, some bike-sharing companies have experienced setbacks and failure in 2018.

Geospatial Network Analysis and Origin-Destination Clustering of Bike-Sharing Activities during the COVID-19 Pandemic

ISPRS International Journal of Geo-Information, 2023
Bike-sharing data are an important data source to study urban mobility in the context of the coronavirus disease 2019 (COVID-19). However, studies that focus on different bike-sharing activities including both riding and rebalancing are sparse.

Networks as signals, with an application to a bike sharing system [PDF]

2013 IEEE Global Conference on Signal and Information Processing, 2013
Dynamic graphs are commonly used for describing networks with a time evolution. A method has been proposed to transform these graphs into a collection of signals indexed by vertices. This approach is here further explored in a number of different directions.

TRIM28‐Derived Peptide Exerts Anti‐Tumor Roles by Stabilizing Tumor Suppressive BRD7 Protein in Multiple Cancers

Advanced Science, EarlyView.
An α‐helical peptide, TAB12, designed to mimic the TRIM28 binding interface, competitively disrupts the TRIM28‐BRD7 interaction, thereby blocking ubiquitin‐mediated degradation of the tumor suppressor BRD7. This stabilization unleashes potent anti‐tumor effects across multiple tumor types with a favorable safety profile, offering a feasible strategy ...

Logical Support for Bike-Sharing System Design [PDF]

, 2019
Automated bicycle-sharing systems (bss) are a prominent example of reconfigurable cyber-physical systems for which the locality and connectivity of their elements are central to the way in which they operate. These features motivate us to study bss from the perspective of Actor-Network Theory – a framework for modelling cyber-physical-system protocols ...

Charting the Path to Increased Oil Palm Output in Ghana Beyond Area Expansion: Technology or Managerial Capacity — Which Leads the Way?

Agribusiness, EarlyView.
ABSTRACT This study sets out to investigate the prospects for raising oil palm output in sub‐Saharan Africa, particularly Ghana, without further expansion of cropland. Given global concerns about oil palm's role in deforestation and land use change, the focus is on enhancing productivity on existing farmlands.
