Zero-knowledge arguments for lattice-based accumulators: logarithmic-size ring signatures and group signatures without trapdoors by Libert, Benoît, Ling, San, Nguyen, Khoa, Wang, Huaxiong

“…As an application, we describe new lattice-based group and ring signatures in the random oracle model. In particular, we obtain: (i) the first lattice-based ring signatures with logarithmic size in the cardinality of the ring and (ii) the first lattice-based group signature that does not require any GPV trapdoor and thus allows for a much more efficient choice of parameters.…”

A high-sensitivity 135GHz millimeter-wave imager by compact split-ring-resonator in 65-nm CMOS by Li, Nan, Yu, Hao, Yang, Chang, Shang, Yang, Li, Xiuping, Liu, Xiong

“…A high-sensitivity 135 GHz millimeter-wave imager is demonstrated in 65 nm CMOS by on-chip metamaterial resonator: a differential transmission-line (T-line) loaded with split-ring-resonator (DTL-SRR). Due to sharp stop-band introduced by the metamaterial load, high-Q oscillatory amplification can be achieved with high sensitivity when utilizing DTL-SRR as quench-controlled oscillator to provide regenerative detection. …”

Binuclear oxidative addition of Sb-Cl bonds : a facile synthetic route to main group transition element clusters and rings by Li, Ying-Zhou, Ganguly, Rakesh, Leong, Weng Kee

“…Binuclear oxidative addition of Sb–Cl bonds with the clusters Os3(CO)11(NCCH3), 1, or Os3(CO)10(NCCH3)2, 2, was found to be an effective synthetic route to organometallic clusters and rings containing μ2-SbPh2 or μ3-SbPh moieties. Thus, the reaction of SbPh2Cl with 1 afforded the tetranuclear ring Os3(CO)11(Cl)(μ-SbPh2), 3, while its reaction with 2 afforded the pentanuclear ring Os3(CO)10(Cl)2(μ-SbPh2)2, 6. …”

Heterogeneity in definitions of surgical site infection after cranial surgery limits the validity of research findings in neurosurgery: a systematic review by Majidi, N, Sivakumar, A, Vogt, A, Ranganathan, S, Ashkan, K, Price, SJ, Lee, KS

“…This heterogeneity has hindered the ability to draw conclusions about the effects of interventions, with only 4.0% of authors accounting for this in their findings. It is important to be cautious when reviewing studies that report SSI-CRAN outcomes without acknowledging this heterogeneity, as the validity of their reported evidence may be limited. …”
