An isolated human cranium, dated to the early Eneolithic period, was discovered in 2015 at the top of a vertical BCAA FX3 shaft in the natural Marcel Loubens gypsum Cave (Bologna area, northern Italy).No other anthropological or archaeological remains were found inside the cave.In other caves of the same area anthropic and funerary use are attested
Introduction: Built and natural environments may provide opportunities for physical activity.However, studies are limited by primarily using residential addresses to define exposure and self-report to measure physical activity.We quantified associations between global positioning systems (GPS)-based activity space measures of environmental exposure
Abstract Effective absorption of low-frequency waterborne sound with subwavelength absorbers has always been a challenging work.In this paper, we derive two theoretical requirements for broadband perfect absorption of low-frequency waterborne sound by ultrathin acoustic metasurface under a finite-thickness steel plate followed by semi-infinite air.
Abstract Given that hypoxia is a persistent physiological feature of many different solid tumors and a key driver for cancer malignancy, it is thought to be a major target in cancer treatment recently.Tumor-associated macrophages (TAMs) are the most abundant immune cells in the tumor microenvironment (TME), which have a large impact on tumor develo
Gas flow in high frequency oscillatory ventilation (HFOV) was numerically investigated.This artificial respiration technique has features of low tidal volume and high frequency.Although ORG KIMCHI molecular diffusion appears to be influential in gas transports at lower airways, the effect of flow convection never vanishes.The present paper is aimed
