As coronavirus disease 2019(COVID-19)public health restrictions are relaxed,the circulation of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)alongside other respiratory viruses may lead to an increased likelihood of coinfection(1).Older patients face a higher risk of severe outcomes,when infected with multiple respiratory viruses(2).This study highlights the successful recovery of the oldest older adult(≥80 years)from pneumonia caused by the dual infection of human respiratory syncytial virus(HRSV)and SARS-CoV-2.

Controlled quantum teleportation(CQT) [1] is the tripartite version of quantum teleportation and it allows the teleportation of an unknown quantum state under the control of a third party. Compared with low-dimensional counterparts,high-dimensional CQT can exhibit larger information transmission capacity and a higher control power [2,3].

Dear Editor,N^(6)-Methyladenine(6mA)DNA modification is an important epigenetic mechanism with roles in regulating gene expression,nucleosome positioning,DNA damage repair,and cell cycle progression(Heyn&Esteller,2015;Luo et al.,2015;Boulias&Greer,2022).Despite progress in understanding the biological functions of 6mA,the contribution of individual 6mA installations on site-specific target genes is largely unknown,and therefore deciphering the molecular mechanism of 6mA in target gene expression has been difficult.
