| 1 | Phase Transformation under Continuous Cooling Conditions in Medium Carbon Microalloyed Steels显示文摘Several 35CrMo4 and 38MnV7 steels with different additions of Ti and V were manufactured by electroslag remelting.The influence of the alloying and microalloying elements on phase transformation at different cooling rates was studied and the continuous cooling transformation diagrams were plotted.In order to optimize the heat treatment and improve the mechanical properties,the range of cooling rates leading to a fully bainitic microstructure(without ferrite,pearlite and especially without martensite)was determined.Bainite and martensite transformation start temperatures(B_s,M_s)were also established and compared with the values predicted by empirical equations.The important role of precipitates(especially V carbonitride particles)on final microstructure and mechanical properties was assessed. | Manuel Gomez Lucia Rancel Esther Escudero Sebastian F.Medina | 2014 | Journal of Materials Science & Technology2014，30，5： | 16 |

| 3 | A tale of worldwide success:Behind the scenes of Carex(Cyperaceae)biogeography and diversification显示文摘The megadiverse genus Carex(c.2000 species,Cyperaceae)has a nearly cosmopolitan distribution,displaying an inverted latitudinal richness gradient with higher species diversity in cold-temperate areas of the Northern Hemisphere.Despite great expansion in our knowledge of the phylogenetic history of the genus and many molecular studies focusing on the biogeography of particular groups during the last few decades,a global analysis of Carex biogeography and diversification is still lacking.For this purpose,we built the hitherto most comprehensive Carex-dated phylogeny based on three markers(ETS-ITS-matK),using a previous phylogenomic Hyb-Seq framework,and a sampling of two-thirds of its species and all recognized sections.Ancestral area reconstaiction,biogeographic stochastic mapping,and diversification rate analyses were conducted to elucidate macroevolutionary biogeographic and diversification patterns.Our results reveal that Carex originated in the late Eocene in E Asia,where it probably remained until the synchronous diversification of its main subgeneric lineages during the late Oligocene.E Asia is supported as the cradle of Carex diversification,as well as a< | Santiago Martin-Bravo Pedro Jimenez-Mejias Tamara Villaverde Marcial Escudero Marlene Hahn Daniel Spalink Eric H.Roalson Andrew L.Hipp the Global Carex Group Carmen Benitez-Benitez Leo P.Bruederle Elisabeth Fitzek Bruce A.Ford Kerry A.Ford Mira Gamer Sebastian Gebauer Matthias H.Hoffmann Xiao-Feng Jin Isabel Larridon Etienne Ldveilld-Bourret Yi-Fei Lu Modesto Luceno Enrique Maguilla Jose Ignacio Marquez-Corro Monica Miguez Robert Naczi Anton A.Reznicek Julian R.Starr | 2019 | Journal of Systematics and Evolution2019，57，6： | 6 |
| 4 | Ontogenetic transition in leaf traits: a new cost associated with the increase in leaf longevity显示文摘Aims Recent work has identified a worldwide‘economics’spectrum of correlated leaf traits that mainly reflects the compromises between maximizing leaf longevity and short-term productivity.However,during the early stages of tree growth different species tend to exhibit a common strategy,because competition for soil water and nutrients forces the maximization of short-term productivity owing to the need for rapid growth during the most vulnerable part of the tree’s life cycle.Accordingly,our aim here was to compare the variations that occur during ontogeny in the different leaf traits(morphology and leaf chemical composition)of several coexisting Mediterranean woody species differing in their leaf life spans and to test our hypothesis that tree species with a long leaf life span should exhibit larger shifts in leaf characteristics along ontogeny.Methods Six Mediterranean tree species differing in leaf life span,selected from three plots located in central-western Spain,were studied during three growth stages:seedlings,juveniles and mature trees.Leaf life span,leaf morphology(leaf area,dry weight,thickness and mass per unit area)and chemical composition(N and fibre con-centrations)were measured in all six species.The magnitude of the ontogenetic changes in the different traits was estimated and related to the mean leaf longevity of the different species.Important Findings Along ontogeny,strong changes were observed in all variables analysed.The early growth stages showed lower leaf thickness,leaf thickness and mass per unit area and N,cellulose and hemi-cellulose concentrations than mature trees,but a higher lignin content.However,these changes were especially marked in species with a longer leaf life span at maturity.Interspecific dif-ferences in leaf life span,leaf morphology and chemical com-position were stronger at the mature stage than at the seedling stage.We conclude that greater plasticity and more intense strat-egy shifts along ontogeny are necessarily associated with long leaf life span.Our results thus provide a new aspect that should be incorporated into the analysis of the costs and benefits associ-ated with the different strategies related to leaf persistence dis-played by the different species.Accordingly,the intensity of the alterations in leaf traits among different growth stages should be added to the suite of traits that change along the leaf economics spectrum. | Sonia Mediavilla Maria Herranz Patricia González-Zurdo Alfonso Escudero | 2014 | Journal of Plant Ecology2014，7，6： | 5 |
| 5 | T_3-induced liver AMP-activated protein kinase signaling:Redox dependency and upregulation of downstream targets显示文摘AIM:To investigate the redox dependency and promotion of downstream targets in thyroid hormone(T3)-induced AMP-activated protein kinase(AMPK)signaling as cellular energy sensor to limit metabolic stresses in the liver.METHODS:Fed male Sprague-Dawley rats were given a single ip dose of 0.1 mg T3/kg or T3 vehicle(Na OH0.1 N;controls)and studied at 8 or 24 h after treatment.Separate groups of animals received 500 mg N-acetylcysteine(NAC)/kg or saline ip 30 min prior T3.Measurements included plasma and liver 8-isoprostane and serumβ-hydroxybutyrate levels(ELISA),hepaticlevels of m RNAs(q PCR),proteins(Western blot),and phosphorylated AMPK(ELISA).RESULTS:T3 upregulates AMPK signaling,including the upstream kinases Ca2+-calmodulin-dependent protein kinase kinase-βand transforming growth factor-β-activated kinase-1,with T3-induced reactive oxygen species having a causal role due to its suppression by pretreatment with the antioxidant NAC.Accordingly,AMPK targets acetyl-Co A carboxylase and cyclic AMP response element binding protein are phosphorylated,with the concomitant carnitine palmitoyltransferase-1α(CPT-1α)activation and higher expression of peroxisome proliferator-activated receptor-γco-activator-1αand that of the fatty acid oxidation(FAO)-related enzymes CPT-1α,acyl-Co A oxidase 1,and acylCo A thioesterase 2.Under these conditions,T3 induced a significant increase in the serum levels ofβ-hydroxybutyrate,a surrogate marker for hepatic FAO.CONCLUSION:T3 administration activates liver AMPK signaling in a redox-dependent manner,leading to FAO enhancement as evidenced by the consequent ketogenic response,which may constitute a key molecular mechanism regulating energy dynamics to support T3preconditioning against ischemia-reperfusion injury. | Luis A Videla Virginia Fernández Pamela Cornejo Romina Vargas Paula Morales Juan Ceballo Alvaro Fischer Nicolás Escudero Oscar Escobar | 2014 | World Journal of Gastroenterology2014，20，46： | 3 |

| 7 | A framework infrageneric classification of Carex (Cyperaceae) and its organizing principles显示文摘Phylogenetic studies of Carex L.(Cyperaceae)have consistently demonstrated that most subgenera and sections are para-or polyphyletic.Yet,taxonomists continue to use subgenera and sections in Carex classification.Why?The Global Carex Group(GCG)here takes the position that the historical and continued use of subgenera and sections serves to(i)organize our understanding of lineages in Carex,(ii)create an identification mechanism to break the~2000 species of Carex into manageable groups and stimulate its study,and(iii)provide a framework to recognize morphologically diagnosable lineages within Carex.Unfortunately,the current understanding of phylogenetic relationships in Carex is not yet sufficient for a global reclassification of the genus within a Linnean infrageneric(sectional)framework.Rather than leaving Carex classification in its current state,which is misleading and confusing,we here take the intermediate steps of implementing the recently revised subgeneric classification and using a combination of informally named clades and formally named sections to reflect the current state of our knowledge.This hybrid classification framework is presented in an order corresponding to a linear arrangement of the clades on a ladderized phylogeny,largely based on the recent phylogenies published by the GCG.It organizes Carex into six subgenera,which are,in turn,subdivided into 62 formally named Linnean sections plus 49 informal groups.This framework will serve as a roadmap for research on Carex phylogeny,enabling further development of a complete reclassification by presenting relevant morphological and geographical information on clades where possible and standardizing the use of formal sectional names. | Eric H.Roalson Pedro Jiménez-Mejías Andrew L.Hipp Carmen Benítez-Benítez Leo P.Bruederle Kyong-Sook Chung Marcial Escudero Bruce A.Ford Kerry Ford Sebastian Gebauer Berit Gehrke Marlene Hahn Muhammad Qasim Hayat Mathias H.Hoffmann Xiao-Feng Jin Sangtae Kim Isabel Larridon Étienne Léveillé-Bourret Yi-Fei Lu Modesto Luceño Enrique Maguilla Jose IgnacioMárquez-Corro Santiago Martín-Bravo Tomomi Masaki Mónica Míguez Robert F.C.Naczi Anton A.Reznicek Daniel Spalink Julian R.Starr Uzma Tamara Villaverde Marcia J.Waterway Karen L.Wilson and Shu-Ren Zhang | 2021 | Journal of Systematics and Evolution2021，59，4： | 3 |

| 11 | Efficient metallization of magnetite concentrate by reduction with agave bagasse as a source of reducing agents显示文摘The reduction behavior and metallization degree of magnetite concentrate with agave bagasse were investigated in an inert atmosphere.The effects of temperature,biomass content,and residence time on reduction experiments and metallization degree were investigated by X-ray diffraction and scanning electron microscopy.Compared with other types of biomass,agave bagasse had lower contents of nitrogen,sulfur,and ash.X-ray diffraction analysis showed that the metallization degree improved with increasing temperature and biomass content.Complete metallization was achieved at 1100℃ for 30 min with 65:35 and 50:50 ratios of the magnetite concentrate to the agave bagasse.These results demonstrate that agave bagasse promotes the efficient metallization of magnetite concentrate without the external addition of a reducing agent.Therefore,this biomass is a technical suitable alternative to replace fossil fuels in steelmaking. | Diana Cholico-González NoemíOrtiz Lara Mario Alberto Sánchez Miranda Ricardo Morales Estrella Ramiro Escudero García Carlos ALeón Patiño | 2021 | International Journal of Minerals,Metallurgy and Materials2021，28，4： | 2 |
