Catalytic Functionalization of Unactivated π‐Bonds Enabled by Bidentate Directing Auxiliaries

open access: yesAngewandte Chemie, EarlyView.
This review explores how bidentate directing auxiliaries have advanced transition‐metal catalysis for unactivated alkene/alkyne functionalization. By leveraging chelated intermediates, bidentate directing auxiliaries enable precise hydrofunctionalization, difunctionalization, and C─H activation of π‐bonds with unique selectivity and reactivity.

Temperature‐Controlled Radiofrequency for Severe Nasal Airway Obstruction: A Non‐Inferiority Comparison With Surgical Intervention

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Temperature‐controlled radiofrequency (TCRF), septoplasty (ST) with turbinate reduction, and functional rhinoplasty (FR) are treatment options for nasal airway obstruction (NAO) and nasal valve dysfunction (NVD), but no direct comparison of these procedures has been performed. Methods This prospective, open‐label, non‐inferiority (

Iterative Synthesis of Pyrene–Coronene Molecular Graphene Nanoribbons

open access: yesAngewandte Chemie, EarlyView.
An iterative approach delivers a new family of undoped, cove‐edged graphene nanoribbons with lengths up to 9.1 nm that exhibit both molar absorptivity and fluorescence brightness values on the order of 105 M−1 cm−1 and an intrinsic charge‐carrier mobility of 475 ± 32 cm2 V−1 s−1.

Congestion pricing vs. slot constraints to airport networks [PDF]

open access: yes
Congestion has become a problem for many airports throughout the world. Two different policy options to control congestion are analyzed in this paper: slot constraints and congestion pricing.

Leptin May Promote Eosinophilic CRSwNP Progression by Enhancing Eosinophil Chemotaxis and Angiogenesis Under a Type 2 Inflammatory Milieu

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyp (CRSwNP) is a heterogeneous Type 2 inflammatory disease characterized by enhanced eosinophilic infiltration. Both innate and adaptive immunity are involved in the onset and progression of CRSwNP.

Coordination‐Driven Direct C─H Metalation of N‐Heterocycles With a Superbasic Co(II) Amide Co(TMP)2

open access: yesAngewandte Chemie, EarlyView.
By enabling regioselectivities that are inaccessible with conventional bases, this study introduces a Co(II) amide platform for the deprotonative C─H metalation of sensitive N‐heterocycles. Subsequent interception of the resulting Co(II) intermediates with external oxidants affords a family of sterically congested, TMP‐substituted heterocycles via C─N ...

TCP Congestion Control Identification

open access: yesCoRR, 2014
Transmission Control Protocol (TCP) carries most of the traffic on the Internet these days. There are several implementations of TCP, and the most important difference among them is their mechanism for controlling congestion. One of the methods for determining type of a TCP is active probing. Active probing considers a TCP implementation as a black box,
