Abstract Understanding the impacts of permafrost thawing on the carbon cycle requires a closer look at the proportion of dissolved and particulate organic carbon released upon thaw, and the magnitude of its conversion into greenhouse gases, which remain critically underexplored. In Central Yakutia (Siberia), we show evidence of contrasting influence of permafrost degradation on dissolved and particulate organic matter in both old and recent thermokarst lakes.

Abstract Quantum key distribution (QKD) protocols most often use two conjugate bases in order to verify the security of the quantum channel. In the majority of protocols, these bases are mutually unbiased to one another, which is to say they are formed from balanced superpositions of the entire set of states in the opposing basis. Here, we introduce a high-dimensional QKD protocol using qubit-like states, referred to as Fourier-qubits (or F-qubits).

Tausende serbische Frauen in Kosovo gingen auf Straßen von Mitrovica, und forderten eine Deeskalation der Spannungen zwischen Belgrad und Pristina. Die haben sich wegen des Streits um serbische Autokennzeichen weiter verschärft. Die kosovarische Regierung droht den Serben mit Geldstrafen, sollten sie weiter serbische Kennzeichen verwenden.
