Production datacenters operate under various uncertainties such as traffic dynamics, topology asymmetry, and failures. Therefore, datacenter load balancing schemes must be resilient to these uncertainties; i.e., they should accurately sense path conditions timely react mitigate the fallouts. Despite significant efforts, prior solutions have important drawbacks. On one hand, Presto DRB are oblivious blindly reroute at fixed granularity. other CONGA CLOVE can congestion, but only when flowlets...
Abstract Construction of C–C bonds via alkoxy radical-mediated remote C(sp 3 )–H functionalization is largely unexplored, as it a formidable challenge to directly generate radicals from alcohols due the high bond dissociation energy (BDE) O–H bonds. Disclosed herein practical and elusive metal-free alcohol-directed heteroarylation unactivated Phenyliodine bis(trifluoroacetate) (PIFA) used only reagent enable coupling heteroaryls. Alkoxy are readily generated free under irradiation visible...
High activity, high stability, and low cost have always been the pursuit of photocatalyst design development. Herein, a simple method is used to integrate abundant anion vacancies (VS) cation (VZn) on surface ZnS (M–ZnS), deriving VS VZn pairs (vacancy pairs), isolated Zn atoms (Zniso), S (Siso). Abundant vacancy defects fully expose activate atoms, regulate band structure, significantly improve separation photogenerated carriers. M–ZnS endowed with average hydrogen production rate optimal...

Inter-data center wide area networks (inter-DC WANs) carry a significant amount of data transfers that require to be completed within certain time periods, or deadlines. However, very little work has been done guarantee such The crux is the current inter-DC WAN lacks an interface for users specify their transfer deadlines and mechanism provider ensure completion while maintaining high utilization. In this paper, we address problem by introducing deadline-based network abstraction (DNA) WANs....

The structure L ‐cysteine‐binding product has been determined by means X‐ray diffraction. replacement...
η2-Iminoketenyl species have often been postulated as the intermediates in nucleophile-induced carbyne–isocyanide C–C coupling processes. However, such are elusive. Here we report direct formation of η2-iminoketenyl complexes from reactions metallapentalyne with isocyanides. Our studies show that steric effects N-substituents isocyanides play an important role stability three-membered metallacycles complexes. Sterically bulky isocyanides, tert-butyl or 1-adamantyl inhibit bending at...
Co-doping of heteroatoms into the support metal-supported catalysts is a prevalent method to improve catalytic performance by adjusting metal–support interactions. This paper investigated performances Ru supported on biomass-derived char (Ru@Char), N-doped (Ru@N-Char), and N,P-co-doped (Ru@NP-Char) in emerging lignin-first depolymerization for both poplar (hardwood) pine (softwood) samples, with an emphasis production phenolic monomers. Various characterizations prepared showed that codoping...
