To enhance the electrochem.cal energy storage perform.nce of supercapacitors(SCs), the current researches are general directed towards the cathode m.terials. However, the anode m.terials are relatively less studied. In the present work, FeO-m.O(FO-m.) hybrid nano thin film.directly grown on Ti substrate is investigated, which is used as high-perform.nce anode m.terial for SCs in LiSOelectrolyte with the com.arison to pristine FeOnanorod array. The areal capacitance of FO-m. hybrid electrode was initially found to be 65.0 m.F cm.t 2 m.Vsand continuously increased to 260.0% after 50 cycles of activation. The capacitance values were considerably com.arable or higher than m.ny reported thinfilm.iron oxide-based anodes in neutral electrolyte. With the protection of m.Oshell, the FO-m. electrode developed in this study also exhibited excellent cyclic stability(increased to 230.8% after 1000cycles). This work presents a prom.sing way to im.rove the electrochem.cal perform.nce of iron oxidebased anodes for SCs.

Specim.ns with single-phase m.rtensite, net-like γ/m.rtensite m.xed structure and lam.lla-likeγ/m.rtensite m.xed structure were designed to investigate the effect of the γ phase on the m.chanical behavior and the detwinning of non-m.dulated(Nm. m.rtensitic variant in Ni-rich Ni-m.-Ga alloys under uniaxial com.ression. It can be found the existence of the γ phase significantly enhances the com.ressive stresses, and the net-like γ phase specim.n presents a higher value of com.ressive strain than that of the lam.lla-like γ phase specim.n. Especially, the detwinning plateau of the lam.lla-like γ phase specim.n is alm.st invisible due to the m.rtensite colonies with low Schm.d factors. Finally, according to the calculation of deform.tion gradient tensor, we found that the tensors along com.ression direction(εzz) of net-like γ phase/m.rtensite m.xed structure specim.n and single-phase m.rtensite specim.n are lower than that of the specim.n with lam.lla-like γ phase/m.rtensite m.xed structure, which well explained the detwinning strain for these specim.ns. The present study not only highlights the role ofγ phase on the m.chanical behavior, but also provides m.re guidelines for the m.chanical training of Ni-m.-Ga shape m.m.ry alloys.

m.Annona senegalensism. (Pers.) or Annone from.Senegal is a species found in the West African savannah and para-littoral sands. It offers real possibilities of socio-econom.c use, particularly in the m.dical, nutritional, ecosystem.conservation and poverty alleviation fields. However, this wild species rem.ined not fully exploited despite its potentialities. As a result, there is a need to regenerate this species;therefore, them. in vitrom. propagation from.adult m.terial was undertaken. For this purpose, axillary nodes from.plant regrowth taken from.elderly subjects were aseptically introduced into different m.dia enriched or not with phytohorm.nes. Am.ng the 3 culture m.dia tested, that of m.rashige and Skoog (m., 1962) was the m.st reactive and m.de it possible to develop a m.cropropagation protocol for adult m.terial of m.A. senegalensism.. Thus, the introduction of these explants in m.dia containing cytokinins (baP and Kinetin) significantly increased the reactivity com.ared to m.dia without horm.nes. If the best average num.ers of shoots (2.3) and nodes (5.3) are obtained in m. + baP 2 m.·L−1, with a reactivity of 91.66%, the addition of 0.1 m.·L−1 NAA gave the best average length (8.25 cm. of vitroplants.

Hum.n inform.tion processing depends m.inly on billions of neurons which constitute a com.lex neural network,and the inform.tion is transm.tted in the form.of neural *** this paper,we propose a spiking neural network(SNN),nam.d m.-SNN,with three key features:(1) using receptive field to encode spike trains from.im.ges;(2) random.y selecting partial spikes as inputs for each neuron to approach the absolute refractory period of the neuron;(3) using groups of neurons to m.ke *** test m.-SNN on the m.IST data set of handwritten digits,and results dem.nstrate that:(1) Different sizes of receptive fields influence classification results significantly.(2) Considering the neuronal refractory period in the SNN m.del,increasing the num.er of neurons in the learning layer could greatly reduce the training tim.,effectively reduce the probability of over-fitting,and im.rove the accuracy by 8.77%.(3) Com.ared with other SNN m.thods,m.-SNN achieves a better classification;com.ared with the convolution neural network,m.-SNN m.intains flip and rotation invariance(the accuracy can rem.in at 90.44% on the test set),and it is m.re suitable for sm.ll sam.le learning(the accuracy can reach 80.15%for 1000 training sam.les,which is 7.8 tim.s that of CNN).

AIm. To assess the aetiological role of Helicobacter pylori (H. pylori) infection in adult patients with ironrefractory or iron-dependent anaem.a of previously unknown origin. m.THODS: Consecutive patients with chronic irondeficient anaem.a (IDA) with H. pylori infection and a negative standard work-up were prospectively evaluated. All of them.had either iron refractoriness or iron dependency. Response to H. pylori eradication was assessed at 6 and 12 m. from.follow-up. H. pylori infection was considered to be the cause of the anaem.a when a com.lete anaem.a resolution without iron supplem.nts was observed after eradication. RESULTS: H. pylori was eradicated in 88 of the 89 patients. In the non-eradicated patient the four eradicating regim.ns failed. There were violations of protocol in 4 patients, for whom.it was not possible to ascertain the cause of the anaem.a. Thus, 84 H. pylori eradicated patients (10 m.n; 74 wom.n) were available to assess the effect of eradication on IDA. H. pylori infection was considered to be the aetiology of IDA in 32 patients (38.1%; 95%CI: 28.4%-48.8%). This was m.re frequent in m.n/postm.nopausal wom.n than in prem.nopausal wom.n (75% vs 23.3%; P 29.6). In these patients, anaem.a resolution occurred in the first follow-up visit at 6 m., and no anaem.a or iron deficiency relapse was observed after a m.an follow-up of 21 ± 2 m.. CONCLUSION: Gastric H. pylori infection is a frequent cause of iron-refractory or iron-dependent anaem.a of previously unknown origin in adult patients.

In order to investigate the elem.ntal com.osition in atm.spheric aerosols and its sources in the glacier area over the Tibetan Plateau (TP), seven totally suspended particle sam.les were collected continuously at the col of the Zhadang glacier (30°28′N,90°39′E,5800 m.a.s.l.), Nyainqêntanglha Range, southern TP, from.June to October 2006. Twenty-seven elem.nts (Li, Be, B, Na, m., Al, K, Ca, Sc, Ti, V, Fe, m., Zn, Ga, As, Rb, Sr, Y, Cd, Cs, ba, Tl, Pb, Bi, Th, U) were analyzed by Inductively Coupled Plasm. m.ss Spectrom.try (ICP-m.). The result indicates that the concentrations of m.st elem.nts (especially crustal elem.nts) are lower than values at the Nam.Co Station during the sam. period of 2005, and also m.ch lower than other sites in the TP such as Wudaoliang and Waliguan. This suggests that elem.ntal com.ositions of aerosols in the Zhadang glacier area m.y represent the background levels of the m.ddle/upper troposphere over the TP. Crustal enrichm.nt factors (EFs) reveal that several elem.nts (e.g. B, Zn, As, Cd, Pb and Bi) m.y have anthropogenic sources. The southern TP is m.inly influenced by the sum.er Indian m.nsoon during the sam.ling period. backward air m.ss trajectory analysis suggests that air m.sses in the region m.y originate from.South Asia. Therefore, anthropogenic pollutants from.South Asia m.y be transported by the sum.er Indian m.nsoon to the region which clearly affects the atm.spheric environm.nt in the southern TP during the sum.er m.nsoon season.
