Cadmium(Cd)and excess molybdenum(Mo)pose serious threats to animal *** previous study has determined that Cd and/or Mo exposure can cause ovarian damage of ducks,while the specific mechanism is still *** further investigate the toxic mechanism of Cd and Mo co-exposure in the ovary,forty 8-day-old female ducks were randomly allocated into four groups for 16 weeks,and the doses of Cd and Mo in basic diet per kg were as follows:control group,Mo group(100 mg Mo),Cd group(4 mg Cd),and Mo+Cd group(100 mg Mo+4 mg Cd).Cadmium sulfate 8/3-hydrate(CdSO_(4)·8/3H_(2)O)and hexaammonium molybdate((NH_(4))_(6)Mo_(7)O_(24)·4H_(2)O)were the origins of Cd and Mo,*** the 16th week of the experiment,all ovary tissues were collected for the detection of related *** data indicated that Mo and/or Cd induced trace element disorders and Th1/Th2 balance to divert toward Th1 in the ovary,which activated endoplasmic reticulum(ER)stress and then provoked necroptosis through triggering riPK1/riPK3/MLKL signaling pathway,and eventually caused ovarian pathological injuries and necroptosis *** alterations of above indicators were most apparent in the joint *** all,this research illustrates that Mo and/or Cd exposure can initiate necroptosis through Th1/Th2 imbalance-modulated ER stress in duck ovaries,and Mo and Cd combined exposure aggravates ovarian *** research explores the molecular mechanism of necroptosis caused by Mo and/or Cd,which reveals that ER stress attenuation may be a therapeutic target to alleviate necroptosis.

Microstructural evolutions of Cu(Ni)/AuSn/Ni joints during reflow

Interfacial reactions of the Ni/AuSn/Ni and Cu/AuSn/Ni joints are experimentally studied at 330℃for various reflow *** microstructures and mechanical properties of the as-solidified solder joints are *** as-solidified solder matrix of Ni/AuSn/Ni presents a typical eutecticξ-(Au,Ni)5Sn+δ-(Au,Ni)Sn lamellar microstructure after reflow at 330℃for 30 *** reflow for 60 s,a thin and flat(Ni,Au)3Sn2intermetallic compound(IMC) layer is formed,and some needle-like(Ni,Au)3Sn2phases grow from the IMC layer into the solder *** the other hand,a cellular-typeξ(Cu) layer is found at the upper AuSn/Cu interface in the Cu/AuSn/Ni joint after reflow for 30 s,and a(Ni,Au,Cu)3Sn2IMC layer is also formed at the lower AuSn/Ni interface. For both joints the IMC layer grows significantly with the increase of reflow time,but the growth rate of(Ni,Au,Cu)3Sn2IMC in the Cu/AuSn/Ni joint is smaller than that of the(Ni,Au)3Sn2layer in the Ni/AuSn/Ni *** comparisons of the shear strength and fracture surface between the Ni/AuSn/Ni and Cu/AuSn/Ni joints suggest that the coupling effect of the Cu/AuSn/Ni sandwich joint is helpful to prevent the excessive growth of(Ni,Au)3Sn2,which in turn enhances the mechanical reliability of the solder joint.

Random bit generators are critical for information security,cryptography,stochastic modeling,and *** and scalability are key challenges faced by current physical random bit ***,we propose a massively parallel scheme for ultrafast random bit generation towards rates of order 100 terabit per second based on a single micro-ring resonator.A modulation-instability-driven chaotic comb in a micro-ring resonator enables the simultaneous generation of hundreds of independent and unbiased random bit streams.A proof-of-concept experiment demonstrates that using our method,random bit streams beyond 2 terabit per second can be successfully generated with only 7 comb *** bit rate can be easily enhanced by further increasing the number of comb lines *** approach provides a chip-scale solution to random bit generation for secure communication and high-performance computation,and offers superhigh speed and large scalability.
