Threshold of Toxicological Concern (TTC) approaches are used for chemical safety assessment and risk-based priority setting for data poor chemicals. TTCs are derived from in vivo No Observed Effect Level (NOEL) datasets involving an external administered dose from a single exposure route, e.g., ...
For this several levels of these parameters are used. For each level of the MTX derivative’s spectra baseline is corrected and is used for further analysis (Supplementary Information). Predicting the survival fraction Predicting the survival fraction of MTX’s derivatives through FTIR spectral data ...
Based on the panel data of 30 provinces (except for Tibet, Hong Kong, Macao, and Taiwan) in China from 2005 to 2016, a nonlinear threshold regression model and a carbon emission expansion models were constructed to empirically analyze the threshold effect of inward foreign direct investment (IFD...

The mechanism of how environmental regulations (ERs) affect export sophistication (ES) is complex, and for many years, it has been a hot topic for researchers. However, few previous studies have focused on whether ERs can promote the upgrading of China’s ES through foreign direct investment (...

(c), respectively.d–fRPOPas a function of <N0> under photon energies below and above MEG threshold for three different sized FAPbI3NCs.RPOPis determined by the PB intensity ratio at the beginning of pump excitation at a delay time of 2 ps to that at a delay time of 4 ns and ...
stable emission of Q-switched pulses was realized under very low pump level, as shown inFig. 6a. The threshold absorbed pump power was only 31 mW for 1% OC. Further increasing the absorbed pump power resulted in a monotonic rise in average output power. The central wavelength was measured...
a solution of MPC (511.6 mg, 1.73 mmol) and Fmoc-protected initiator (5.8 mg, 0.010 mmol) in degassed methanol (1.0 mL) in a nitrogen glove box. The mixture was stirred at room temperature for 4 days. When the reaction was complete, the solution was passed through a thin silica gel ...
with a threshold energy density of ~200 µJ/cm2under 440 nm excitation. Excitation at 500 nm, on the other hand, needed a higher threshold energy density of ~255 µJ/cm2. The ASE threshold carrier density, on the other hand, was expected to be ~4.5 × 1018cm−3for both ...
