Neurological consequences of human calmodulin mutations

When calcium ions enter the cytosol,it is a stimulatory signal for cellular events.The calcium sensor calmodulin picks up the change in calcium concentration and relays this information to its more than 300 downstream interaction partners.In this way,calmodulin affects cellular processes such as fertilization,muscle contraction,neuronal firing,and apoptosis.That is,calmodulin is involved in(nearly)everything!The significance of calmodulin is emphasized by the fact that we all carry three different genes(CALM1,2,3)on different chromosomes that encode the exact same calmodulin protein,and these are all expressed in all cell types.Moreover,throughout vertebrate evolution,the protein sequence has remained completely unchanged.

WHEN EAST MEETS WEST IN URBAN DESIGN

No matter how the world changes,people’s aspiration for a better living environment remains unchanged.Urban planners factor this in their blueprints and different eras give different characteristics to urban design and architecture.Modernization,technological progress,cultural trends,and social issues have all become drivers of urban planning and building design.In addition,architects and urban planners worldwide have to consider several crucial issues today-how to tackle climate change by reducing carbon emission in construction and improving the ecological environment in urban design,how to revitalize ancient cultural heritage,and how to create a new,sustainable urban culture.

Tomato SlAN11 regulates flavonoid biosynthesis and seed dormancy by interaction with bHLH proteins but not with MYB proteins

The flavonoid compounds are important secondary metabolites with versatile human nutritive benefits and fulfill a multitude of functions during plant growth and development.The abundance of different flavonoid compounds are finely tuned with species-specific pattern by a ternary MBW complex,which consists of a MYB,a bHLH,and a WD40 protein,but the essential role of SlAN11,which is a WD40 protein,is not fully understood in tomato until now.In this study,a tomato WD40 protein named as SlAN11 was characterized as an effective transcription regulator to promote plant anthocyanin and seed proanthocyanidin(PA)contents,with late flavonoid biosynthetic genes activated in 35S::SlAN11 transgenic lines,while the dihydroflavonol flow to the accumulation of flavonols or their glycosylated derivatives was reduced by repressing the expression of SlFLS in this SlAN11-overexpressed lines.The above changes were reversed in 35S::SlAN11-RNAi transgenic lines except remained levels of flavonol compounds and SlFLS expression.Interestingly,our data revealed that SlAN11 gene could affect seed dormancy by regulating the expressions of abscisic acid(ABA)signaling-related genes SlABI3 and SlABI5,and the sensitivity to ABA treatment in seed germination is conversely changed by SlAN11-overexpressed or-downregulated lines.Yeast two-hybrid assays demonstrated that SlAN11 interacted with bHLH but not with MYB proteins in the ternary MBW complex,whereas bHLH interacted with MYB in tomato.Our results indicated that low level of anthocyanins in tomato fruits,with low expression of bHLH(SlTT8)and MYB(SlANT1 and SlAN2)genes,remain unchanged upon modification of SlAN11 gene alone in the transgenic lines.These results suggest that the tomato WD40 protein SlAN11,coordinating with bHLH and MYB proteins,plays a crucial role in the fine adjustment of the flavonoid biosynthesis and seed dormancy in tomato.

The influence of DC stray current on pipeline corrosion

DC stray current can cause severe corrosion on buried pipelines.In this study,firstly,we deduced the equation of DC stray current interference on pipelines.Next,the cathode boundary condition was discretized with pipe elements,and corresponding experiments were designed to validate the mathematical model.Finally,the numerical simulation program BEASY was used to study the corrosion effect of DC stray current that an auxiliary anode bed generated in an impressed current cathodic protection system.The effects of crossing angle,crossing distance,distance of the two pipelines,anode output current,depth,and soil resistivity were investigated.Our results indicate that pipeline crossing substantially affects the corrosion potential of both protected and unprotected pipelines.Pipeline crossing angles,crossing distances,and anode depths,our results suggest,have no significant influence.Decreasing anode output current or soil resistivity reduces pipeline corrosion gradually.A reduction of corrosion also occurs when the distance between two parallel pipelines increases.

Effect of Grain Boundary on Spinodal Decomposition Using the Phase Field Crystal Method

Spinodal decomposition (SD) with different grain boundaries (GBs) is investigated on the atomic scale using the novel phase field crystal model.It is demonstrated that the decomposition process is initiated by precipitating one phase with a larger lattice constant in the tension region at the GBs and the other one with a smaller lattice constant in the compression region.As the phase separation proceeds,the dislocations comprising the low-angle GBs migrate toward the compositional domain boundaries to relieve the coherent strain energy,and eventually become randomly distributed in the coarsening regime of SD,which leads to the disappearance of the low-angle GBs.For high-angle GBs,the location of GBs remains unchanged,while the atoms rearrange along the GBs to fit the stress field arising from compositional inhomogeneity.

“Survival of the Fittest” in The Call of the Wild

Jack London(1876-1916) is known as an American novelist in the early 20 th century. He lived in the gilded times that were full of different kinds of trend of thought in literature and art. His experiences made his life more colorful. He saw the cruelty of Capitalism and spoke for Socialism with his words. His novels, The Call of the Wild, The leading character, in their own way, witnessed the survival of the fittest in their life. Jack London told the unchanged truth — the survival of the fittest in his brilliant words. It is difficult to change the world, but easy to change oneself. One adjusts to his life space with his"evolution",and one goes in a new environment where every cloud has a silver lining.

Characteristics of Soliton Evolution in the Wave-Breaking-Free Regime in a Passively Mode-Locked Yb-Doped Fiber Laser

We focus on several aspects concerning the numerical simulation of a passively mode-locked Yb-doped fiber laser by a non-distributed model.The characteristics of soliton evolution in a wave-breaking-free regime are numerically investigated with the split-step Fourier method.Based on the model,a parabolic-shaped soliton with a nearly linear chirp and bound soliton pairs are obtained by controlling the intra-cavity average dispersion of the fiber laser.A phenomenon is observed that by keeping the system parameters unchanged,linearly chirped parabolic soliton and bound soliton pairs are attainable under different initial conditions in the transient region between these two kinds of solitons.

Nonlinear Electrical Behaviour of the TiO_(2)·Y_(2)O_(3)·Nb_(2)O_(5) System

The nonlinear properties and the dielectric properties of a new TiO_(2)-based varistor system,TiO_(2)·Y_(2)O_(3)·Nb_(2)O_(5),have been investigated.The(Nb,Y)-doped TiO_(2)ceramics have nonlinear coefficients of α=5-8 and a lower breakdown electrical field of 6-12V·mm^(-1),in which the varistor of(99.3mol%)TiO_(2).(0.6mol%)Y_(2)O_(3).(0.1mol%)Nb_(2)O_(5)composite sintered at 1400℃ has a nonlinear coefficient of α=7.8 and a maximum breakdown electrical field of 12 V·mm^(-1) at 1 mA·cm^(-2).Also,the relative dielectric constants of the composite reach more than 85000,which is almost unchanged within the temperature range from-20 to 280℃ and the frequency range of 0.5 K-2 MHz.Due to these properties the(Nb,Y)-doped TiO_(2)varistors has varistor capacitance bifunctional components,which are quite useful in the situation that the voltage protection and high frequency noise absorption are meanwhile required.

Low-Temperature Baking Effect of the Radio-Frequency Nb_(3)Sn Thin Film Superconducting Cavity

The Nb_(3)Sn thin film cavity,having the potential to be operated at a higher temperature and higher gradient compared to the cavity made from bulk niobium,is one of the most promising key technologies for the nextgeneration radio-frequency superconducting accelerators.In our work,several 1.3 GHz single-cell TESLA-shaped Nb_(3)Sn thin film cavities,coated by the vapor diffusion method,were tested at Peking University and Institute of Modern Physics,Chinese Academy of Sciences.It was observed that the performance of the Nb_(3)Sn thin film cavities in the tests without the slow cooling down procedure and the effective magnetic field shielding was significantly improved by using a low temperature baking at 100℃for 48 hours.Although the peak electric field of the cavity remained unchanged,the rapid drop of the unloaded Q value(Q0)with the increasing accelerating field(Q-slope)was effectively eliminated,resulting in an improvement of the Q0 in the intermediate field region by~8 times.Furthermore,under better test conditions with the shielded magnetic field less than 5 mG and the slow cooling down procedure in the temperature range of 25-15 K,the Q0 was still improved by about 20%.Our study shows that the low temperature baking can be an effective supplement to the effective post-treatment for the Nb_(3)Sn thin film cavity.

Structural and Optical Characterizations of ZnO Films Grown by Reactive Electron Beam Evaporation

Low temperature epitaxial growth of ZnO films is achieved on Si(001)substrates by reactive electron beam evap oration.Growth temperature is varied from 125 C to 420 C and the optimum temperature is found between 200°C and 300 C.X-ray diffraction shows that the ZnO films are highly c-axis oriented and the line width of(002)diffraction peak is significantly smaller than that measured from the ZnO films deposited by magnetron sput tering.The combined photoluminescence and photoluminescence excitation(PLE)spectroscopic measurements demonstrate the sharp band-absorption edge and exciton absorption in the ZnO films.PLE has also revealed that the absorption characteristic near the band edge is remarkably improved with the increase of oxygen content in the ZnO films,although x-ray diffraction analysis shows that the crystalline structure of ZnO films grown under different oxygen pressures remains unchanged.
