Tropical forests have a mitigating effect on man-made climate change by acting as a carbon sink. For that effect to continue, tropical trees will have to acclimate to rising temperatures, but it is currently unknown whether they have this capacity. We grew seedlings of three tropical tree species over a range of temperature regimes (TGrowth = 25, 30, 35 °C) and measured the temperature response...

The high seismic hazard of the Italian territory and vulnerability its historic masonry heritage require development fragility curves that must be increasingly reliable robustly correlated to exposure. To date, national-scale risk analyses mainly use empirical derived from statistical analysis damage induced by past events. These have shown good reliability, but they correlate only with a few t...

Antiretroviral therapy has improved the quality and length of life of millions of individuals affected by human immunodeficiency virus type 1 (HIV-1). The capacity of these drugs to indefinitely suppress HIV-which has a well-known capacity for escaping antiviral pressures-is surprising. In this issue of Science Translational Medicine, Shen et al. use a combination of mathematical modeling and e...

The results showed that (1) the ultimate shear deformation of the rubber bearings with two fixed end plates reached 300% to 400% of the rubber layer thickness. The damage was mainly focused on the rubber layer fracture. The energy dissipation capacity of the bearings was weak, and the hysteresis curve presented a narrow zonal shape. (2) The rubber bearings with unilateral friction sliding had a...

We consider a generalized two-species population dynamic model and analytically solve it for the amensalism and commensalism ecological interactions. These two-species models can be simplified to a one-species model with a time dependent extrinsic growth factor. With a one-species model with an effective carrying capacity one is able to retrieve the steady state solutions of the previous one-sp...

We propose a capacity driven pricing mechanism for several service industries in which the customer behavior, the price demand relationship, and the competition are significantly distinct from other industries. According our observation, we found that the price demand relationship in these industries cannot be modeled by fitted curves; the customers would neither plan in advance nor purchase th...

High concentrations of thyroid-stimulating hormone (TSH) in the serum have often been reported in apparently euthyroid patients with damaged thyroids. We have confirmed this finding in 14 patients 18 months after subtotal thyroidectomy for Graves's disease (group 1) and in 14 patients with manic-depressive psychosis (group 2) receiving lithium carbonate, which reduces thyroid reserve. One facto...

Based on the excellent performance of shear metal dampers in building seismic capacity, traditional damper was optimized. A double-sided steel tube with simple structure, easy replacement, and wide application is proposed. In order to study influence different design parameters its performance, taking length, height, width, thickness, connection mode as variables, five groups 15 specimens were ...

The effect of lead on GABAB binding was studied on membranes obtained from acute and chronically lead-treated rats. Acute lead treatment reduced both GABAB affinity (KD) by about 30% and density of receptor (Bmax) by about 15%. On the contrary chronic lead treatment increased receptor capacity by about 20% in spite of decreased receptor affinity by 25%. Both acute and chronic lead treatment shi...
