Abstract The double-cone geometry is a saddle of the gravitational path integral, which explains the chaotic statistics of the spectrum of black hole microstates.This geometry is the usual AdS-Schwarzschild black hole, but with a periodic identification of the time coordinate; the resulting singularity at the black hole horizon is regulated by maki
Abstract River rhythmicity refers to the periodic, recurrent phenomena of a riverscape that are synchronized with the rise and fall of river water, creating regimes of river time.River rhythmicity can serve as a lens into the coq-clear 100 ubiquinol temporal dimension of river formation and socio‐ecological dynamics that are of great interest to
Recently, the mobile wheeled inverted pendulum (MWIP) has gained an increasing interest in the field of robotics due to traffic and environmental protection problems.However, the MWIP system is characterized by its nonlinearity, underactuation, time-varying parameters, and natural instability, which make its modeling and control challenging.Traditi
The African assassin bug genus Neopirates Miller, 1952, is revised.The type species, N.nyassae Miller, 1952, is redescribed and illustrated; two new species from Namibia, N.bicolor Liu & Cai sp.n.and N.xanthothorax Liu & Cai sp.n.are described and a key is provided offworld drum pads to separate the three species of this genus.Sphodrembas fumipenni
Tire rolling resistance has a major impact on vehicle fuel consumption.Rolling resistance is the loss of energy due to the interaction between the tire and the pavement surface.This interaction is a complicated combination of stresses and strains which depend on both tire and pavement related factors.These include vehicle speed, vehicle weight, tir
