Based on the dynamic governing equation of propagating buckle on a beam on a nonlinear elastic foundation, this paper deals with an important problem of buckle arrest by combining the FEM with a time integration technique. A new conclusion completely different from that by the quasi-static analysis about the buckle arrestor design is drawn. This shows that the inertia of the beam cannot be ignored in the analysis under consideration, especially when the buckle propagation is suddenly stopped by the arrestors.

Calcium ion is a versatile second messenger for diverse cell signaling in response to developmental and environmental cues. The specificity of Ca^2＋-mediated signaling is defined by stimulus-elicited Ca^2＋ signature and down-stream decoding processes. Here, an Aequorin-based luminescence recording system was developed for monitoring Ca^2＋ in response to various stimuli in Arabidopsis. With the simple, highly sensitive, and robust Ca^2＋ recording, this system revealed stimulus-and tissue-specific Ca^2＋ signatures in seedlings. Cellular Ca^2＋ dynamics and relationship to Aequorin-based Ca^2＋ recording were explored using a GFP-based Ca^2＋ indicator, which suggested that a synchronous cellular Ca^2＋ signal is responsible for cold-induced Ca^2＋ response in seedlings, whereas asynchronous Ca^2＋ oscillation contributes to osmotic stress-induced Ca^2＋ increase in seedlings. The optimized recording system would be a powerful tool for the iden-tification and characterization of novel components in Ca^2＋ -mediated stress-signaling pathways,

THE procedure of inertial confinement fusion (ICF) takes place in sub-nanosecond period. Inorder to investigate the hydrodynamic instability and asymmetry during the implosion, weneed to measure the two-dimensional distribution of plasmas temperature and density as well asits relationship with time. For this purpose, an X-ray picosecond multiframe technique hasbeen developed.

Purpose: The aim of the present study was to evaluate the characteris tics of spasticity-related pain(SRP) and the correlation between SRP and gross motor capability in children and adolescents with cerebral palsy. Methods:137 caregivers/parents and 120 children/adolescents with cere bral palsy(age 2-17 years)who have upper limbs and/or lower limbs SRP were recruited from three Chinese study sites. The SRP was assessed b y the Questionnaire on Pain caused by Spasticity(QPS), including a s elf-report version, an interview-version for the children/adolescent and a proxy-report version for the parent(s)/caregivers. All the chil dren and adolescents were measured for gross motor functions by G ross Motor Function Classification System-Expanded & Revised(GMFCS E&R) and Gross Motor Function Measure-66( GMFM-66), Spearman’s rank correlation coefficients was used to determine the correlation betwe en QPS scores and GMFCS E&R and GMFM-66. Results: The greatest amount of SRP was found when the child was rece iving "physical therapy or stretching exercises". QPS scores have p ositive correction with the gross motor function as assessed by the G MFCS E&R in child interviewed group(lower limb r=0.533,p<0.001;upper limb r=0.644,p<0.013). QPS scores in child interviewer-administered group are in several cases associated with gross motor function as me asured by the GMFM-66. Conclusions: The SRP in children and adolescents with cerebral palsy tended to correlate with gross motor function. More methods and measu res are needed to manage and treat the SRP in children and adolescent s.

Adsorption,absorption and diffusion pathways of nitrogen are studied for ferromagnetic body-centered cubic iron via spin-polarized density functional theory in combination with the climbing image nudged elastic band *** computed data suggest that,depending on the coverage of N atoms,N prefers to stay on particular surface *** pinned down well below the surface,N prefers to move into octahedral interstices rather than tetrahedral ***,the tetrahedral interstices are crucial because they act as transition states and yield the saddle point energies of the corresponding minimum energy *** comparison with carbon,we found that nitrogen prefers a different pathway from the(1 0 0)surface to the subsurface due to its strong repulsive interaction with Fe ions.
