Implementation Punctuation: The Role of Feedback, Narratives, and Implementation in the Punctuated Equilibrium Theory

Policy Studies Journal, EarlyView.
ABSTRACT Based on the Punctuated Equilibrium Theory (PET) and implementation research, this study proposes an extended conceptualization of policy punctuation that enables researchers to systematically include policy implementation as part of a punctuation. The key mechanisms underlying the PET, i.e., policy image and venue, information processing, and

Five‐year outcomes of pembrolizumab versus chemotherapy in Chinese patients with non‐small‐cell lung cancer and programmed cell death ligand 1 tumor proportion score ≥1%: KEYNOTE‐042 China study

International Journal of Cancer, Volume 158, Issue 9, Page 2429-2439, 1 May 2026.
What's new? Global research has found that for people newly diagnosed with advanced non‐small cell lung cancer (NSCLC), the anti‐PD‐1 monoclonal antibody pembrolizumab on its own often leads to better results than traditional chemotherapy. The present report details long‐term findings of pembrolizumab therapy specifically among Chinese patients.

Distanzabhängiger Energietransfer zwischen organischen Fluorophoren und einwandigen Kohlenstoffnanoröhren

Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.
Wir zeigen, dass hybridisierte dsDNA eine senkrechte Ausrichtung zu SWCNTs einnimmt, und präsentieren eine abstandsabhängige Übertragung der Energie von Fluoreszenzfarbstoffen auf SWCNTs. Der Energietransfer von Kohlenstoffnanoröhren (CNET) folgt einer d−5‐Abhängigkeit mit einem charakteristischen Abstand von 7,4 nm (± 0,7 nm) für 50 % Energietransfer.

Dynamischer Austausch von Bindemolekülen steigert die Effizienz der Proteinmarkierung in DNA‐PAINT um das bis zu 15‐Fache

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Der dynamische Austausch von Bindemolekülen (Dynamic Binder Exchange; DyBE) nutzt transiente Binde–Zielprotein‐Interaktionen, um die Markierungseffizienz in der superauflösenden Mikroskopie um das 15‐Fache zu steigern. DyBE kartiert die Organisation von Rezeptor‐Tyrosinkinasen (RTKs), einschließlich HER2‐Homodimere und EGFR–HER2‐Heterodimere, auf der ...

Vibration‐controlled transient elastography in pediatric metabolic dysfunction‐associated steatotic liver disease

Journal of Pediatric Gastroenterology and Nutrition, Volume 82, Issue 3, Page 741-750, March 2026.
Abstract Objectives Metabolic dysfunction‐associated steatotic liver disease (MASLD) is a prevalent disease in children. Vibration‐controlled transient elastography (VCTE) offers a noninvasive alternative to liver biopsy, using controlled attenuation parameter (CAP) to estimate steatosis and liver stiffness measurement (LSM) for fibrosis.

Drought reduces the value of both artificial and natural wetlands for gulls breeding in the Mediterranean region

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
The importance of artificial wetlands for waterbird conservation can be easily overestimated from count data alone. The value of extensive fish ponds as a breeding habitat depends on maintaining the availability of natural marshes as a foraging habitat. This requires reducing impacts from groundwater extraction. Given recent abandonment of aquaculture,
