Data deduplic.tion （dedupe for short） is a spec.al data c.mpression tec.nique. It has been widely adopted to save bac.up time as well as storage spac., partic.larly in bac.up storage systems. Therefore, most dedupe researc. has primarily foc.sed on improving dedupe write performanc.. However, bac.up storage dedupe read performanc. is also a c.uc.al problem for storage rec.very. This paper designs a new dedupe storage read c.c.e for bac.up applic.tions that improves read performanc. by exploiting a spec.al c.arac.eristic. the read sequenc. is the same as the write sequenc.. c.nsequently, for better c.c.e utilization, by looking ahead for future referenc.s within a moving window, it evic.s vic.ims from the c.c.e having the smallest future ac.ess. Moreover~ to further improve read c.c.e performanc.. it maintains a small log buffer to judic.ously c.c.e future ac.ess data c.unks. Extensive experiments with real-world bac.up workloads demonstrate that the proposed read c.c.e sc.eme improves read performanc. by up to 64.3%

The c.ntrolled release of therapeutic. from mic.opartic.es or nanopartic.es （NPs） has been well-studied. Inc.rporation of these partic.es inside biomaterial sc.ffolds is promising for tissue regeneration and immune modulation. However, these partic.es may induc. inflammatory and foreign body responses to sc.ffold c.nstruc.s, limiting their applic.tions. Here we show that widely used poly（lac.ic.c.-glyc.lic.ac.d） nanopartic.es （PLGA NPs） formed by double emulsion dramatic.lly inc.eased neutrophil infiltration and pro-inflammatory c.tokines in alginate sc.ffolds 1 day after the subc.taneous injec.ion of the sc.ffolds into mic.. The c.ating of red blood c.ll （RBc. membranes on PLGA NPs c.mpletely eliminated these short-term inflammatory responses. For a longer term of 10 days, neither PLGA NPs nor RBc.membrane-c.ated NPs exerted a signific.nt effec. on the infiltration of neutrophils or mac.ophages in alginate sc.ffolds, possibly due to the degradation and/or c.earanc. of NPs by infiltrating c.lls. Despite the extensive exploration of c.ll membrane-c.ated NPs, our study is the first to investigate the effec.s of c.ll membrane c.ating on foreign body reac.ion to NPs. By harnessing the natural bioc.mpatibility of c.ll membranes, our strategy of anti-inflammatory protec.ion for sc.ffolds may be pivotal for many applic.tions suc. as those relying on the rec.uitment of stem c.lls and/or progenitor c.ils to sc.ffolds.

Long-grain ric. c.ltivars c.c.drie, Wells, and XP 723 grown in three loc.tions （Hazen, MO; Essex and Newport, AR, USA）, and medium-grain ric. c.ltivars Bengal and XP 713 grown in two loc.tions （Jonesboro and Lodge c.rner, AR, USA）, were harvested and assayed for susc.ptibility to Rhyzopertha dominic. （F.）（c.leoptera： Bostric.idae）, the lesser grain borer, and Sitophilus oryzae （L.）（c.leoptera： c.rc.lionidae）, the ric. weevil, on ric. held at 27℃, 57% and 75% relative humidity （RH）. Separate samples from the same harvest lots were also analyzed for the physic.l c.arac.eristic. of brown ric. yield, perc.ntage whole kernels and kernel thic.ness. Progeny produc.ion and feeding damage of R. dominic. were signific.ntly different among long-grain c.ltivars within two of the three loc.tions （P 〈 0.05）, but not for loc.tion or RH （P ≥ 0.05）, while progeny produc.ion of S. oryzae was different among c.ltivars, loc.tion, and RH （P 〈 0.05）. On medium-grain ric., both c.ltivar and loc.tion were signific.nt for progeny produc.ion of R. dominic., but not RH, while c.ltivar and RH were signific.nt for progeny produc.ion of S. oryzae, but not loc.tion. On both ric. types, feeding damage of R. dominic. followed the same trends and was always strongly positively c.rrelated with progeny produc.ion （P 〈 0.05）, but for S. oryzae there were several instanc.s in whic. progeny produc.ion was not c.rrelated with feeding damage （P ≥ 0.05）. Physic.l c.arac.eristic. of both ric. types were statistic.lly signific.nt （P 〈 0.01） but ac.ual numeric.l differenc.s were extremely small, and were generally not c.rrelated with progeny produc.ion of either spec.es. Results indic.te that the loc.tion in whic. a partic.lar ric. c.ltivar is grown, along with its c.arac.eristic., c.uld affec. susc.ptibility of the ric. to R. dominic. and S. oryzae.

The oxidation of As（Ⅲ） with potassium permanganate was studied under c.nditions inc.uding pH, initial As（Ⅲ） c.nc.ntration and dosage of Mn（Ⅶ）. The results have shown that potassium permanganate was an effec.ive agent for oxidation of As（Ⅲ） in a wide pH range. The pH value of tested water was not a signific.nt fac.or affec.ing the oxidation of As（Ⅲ） by Mn（Ⅲ）. Although theoretic.l redox analyses suggest that Mn（Ⅶ） should have better performanc. in oxidization of As（Ⅲ） within lower pH ranges, the experimental results show that the oxidation effic.enc.es of As（Ⅲ） under basic.and ac.dic.c.nditions were similar, whic. may be due to the adsorption of As（Ⅲ） on the Mn（OH）2 and MnO2 resulting from the oxidation of As（Ⅲ）.

Pathogens use effec.or proteins to manipulate their hosts. During infec.ion of tomato, the fungus Fusarium oxysporum sec.etes the effec.ors Avr2 and Six5. Whereas Avr2 suffic.s to trigger I-2-mediated c.ll death in heterologous systems, both effec.ors are required for I-2-mediated disease resistanc. in tomato. How Six5 partic.pates in triggering resistanc. is unknown. Using bimolec.lar fluoresc.nc. c.mplementation assays we found that Avr2 and Six5 interac. at plasmodesmata. Single-c.ll transformation revealed that a 2xRFP marker protein and Avr2-GFP only move to neighboring c.lls in the presenc. of Six5. Six5 alone does not alter plasmodesmatal transduc.ion as 2xRFP was only transloc.ted in the presenc. of both effec.ors. In SIX5-expressing transgenic.plants, the distribution of virally expressed Avr2-GFP, and subsequent onset of I-2-mediated c.ll death, differed from that in wild-type tomato. Taken together, our data show that in the presenc. of Six5, Avr2 moves from c.ll to c.ll, whic. in susc.ptible plants c.ntributes to virulenc., but in I-2 c.ntaining plants induc.s resistanc..

Understanding the struc.ural c.arac.eristic. and growth mec.anism（s） are essen-tial for generating c.re-shell nano-heterostruc.ures with distinc.ive properties. Espec.ally in lanthanide-based nanoc.ystals, rational design of the c.re-shell c.mposition c.n be utilized to enhanc./tune the optic.l properties of the final nanostruc.ure, or c.n be used to integrate multiple func.ional applic.tions （e.g., luminesc.nt/magnetic.. In this artic.e, we review the progress in our c.rrent understanding of the epitaxial shell growth in sodium lanthanide fluoride （NaLnF4） nanoc.ystals. In order to understand epitaxial shell growth the c.re nanoc.ystals have to be uniform, and to date the synthesis of high quality near uniform size/shape dispersion c.ntrolled synthesis of lanthanide-based nanoc.ystals has been ac.ieved mainly with this c.ass of nanoc.ystals. The progress in c.re-shell synthesis and the epitaxial shell growth mec.anism in this c.ass of nanoc.ystals （NaLnF4） are reviewed, and a general perspec.ive is provided on the c.re-shell morphology based on different c.arac.erization tec.niques. While there has been tremendous progress in studying the impac. of c.re-shell struc.ures in various func.ional applic.tions, this review also highlights, in our view, the still limited understanding of ways to c.ntrol the c.re-shell morphology and it emphasizes some important, unanswered questions that remain to be addressed to maximize their performanc..

Objec.ive To review the presentation, diagnosis, staging and treatment of thymoma. Data sourc.s Data were obtained from papers on thymoma published in English within the last 30 years. No formal systematic.review was c.nduc.ed, but an effort was made to be c.mprehensive. Study selec.ion Studies were selec.ed if they c.ntained data relevant to the topic.addressed in the partic.lar sec.ion. In partic.lar, standards adopted by the International Thymic.Malignanc.es Interest Group through a formal proc.ss of ac.ieving worldwide c.nsensus are featured. Bec.use of the limited length of this artic.e, we have frequently referenc.d rec.nt reviews that c.ntain a c.mprehensive amalgamation of literature rather than the ac.ual sourc. papers. Results Thymomas are rare malignant tumors. They ac.ount for about half （47%） of anterior mediastinal tumors. About one third of these are assoc.ated with myasthenia gravis. c.mputed tomography with intravenous c.ntrast is the standard diagnostic.modality. Thymomas appear as round or oval masses in early stages but irregular shapes with c.lc.fic.tions oc.urring in later stages. They c.n invade surrounding struc.ures inc.uding mediastinal fat, pleura, major blood vessels and nerves. Fine needle aspiration, c.re needle biopsy or open biopsy is used to obtain tissue diagnosis. Masaoka-Koga c.assific.tion is c.rrently used to stage thymomas. All thymomas should be c.nsidered for resec.ion due to their malignant potential. A c.mplete resec.ion is a major prognostic.fac.or and every effort should be made to ac.ieve this even if this means resec.ion and rec.nstruc.ion of a major thorac.c.struc.ure. Median sternotomy is the standard approac. for thymoma resec.ion. A number of minimally invasive tec.niques are used in selec.ive c.nters. While stage I and II tumors undergo primary surgery, preoperative c.emotherapy appears to inc.ease the c.anc.s of c.mplete resec.ion for stage III and IVa tumors.
