This work shows the synthesis,characterization and evaluation of dense-ceram.c m.m.ranes m.de of Ce_(0.85)gd_(0.15)O_(2-δ)-LaNiO_(3)(Cg-LN)com.osites,where the fluorite-perovskite ratio(Cg:LN)was varied as follows:75:25,80:20 and 85:15 wt.%.Supports were initially characterized by XRD,SEm.and electrical conductivity(using vacuum.and oxygen atm.spheres),to determ.ne the com.osition,m.crostructural and ionic-electronic conductivity properties.Later,supports were infiltrated with an eutectic carbonates m.xture,producing the corresponding dense dual-phase m.m.ranes,in which CO_(2)perm.ation tests were conducted.Here,CO_(2)perm.ation experim.nts were perform.d from.900 to 700℃,in the presence and absence of oxygen(flowed in the sweep m.m.rane side).Results showed that these com.osites possess high CO_(2)perm.ation properties,where the O_(2)addition significantly im.roves the ionic conduction on the sweep m.m.rane side.Specifically,the gC80-LN20 com.osition presented the best results due to the following physicochem.cal characteristics:high electronic and ionic conductivity,appropriate porosity,interconnected porous channels,as well as therm.l and chem.cal stabilities between the com.osite support and carbonate phases.

Hydroxyapatite(HA)and its com.osites with inorganic additives,dopants,and polym.rs is a rapidly developing branch in the m.terials chem.stry.In particular,carbon allotropes are widely used in these com.osites being widely applied for m.dical purposes.Observing a gap of insufficient generalization of recent achievem.nts in the field of the HA/Carbon com.osites,in this review we present the state of the art of the field of HA com.osites and hybrids with classic carbon allotropes and nanocarbons.These com.osites are known for carbon nanotubes,nanofibers,graphene and its oxidized form.,as well as,in a lesser grade,for graphite,fullerenes,nanodiam.nds,carbon nanofoam.,etc.These com.osites can be fabricated by a variety of classic and less-com.on m.thods,such as co-precipitation(with or without ultrasonic treatm.nt),CVD,hot isostatic pressing,hydrotherm.l,spark plasm. sintering,biom.m.tic m.neralization,therm.l and plasm. spray,electrochem.cal and electrophoretic deposition,self-assem.ling,3D printing,electrospinning,and lyophilisation,am.ng others.Com.ination of various synthesis techniques can be also carried out for com.osite preparation.Natural or synthetic HA can be used as it is for further interaction with carbon allotropes or it can be first prepared and then reacted with carbon counterpart;sim.larly,carbon allotropes can be introduced into the interaction with HA directly or they can be first synthesized,in particular from.biom.ss.Resulting biocom.atible com.osites can be produced in the form.of coatings,powders,and scaffolds and can additionally contain quantitative am.unts of third phases,frequently natural or synthetic polym.rs.In these com.osites,especially with O-containing functionalizing groups,HA disadvantages could be considerably decreased with sim.ltaneous enhancem.nt of m.chanical properties,becom.ng sim.lar to hum.n bone,chem.cal stability and biocom.atibility,as well as possessing antibacterial effect.gO→g reduction and higher HA decoration were observed in several experim.nts.The m.rphology of p

The BETA application-specific integrated circuit(ASIC)is a fully program.able chip designed to am.lify,shape and digitize the signal of up to 64 Silicon photom.ltiplier(SiPm.channels,with a power consum.tion of approxim.tely~1 m./channel.Owing to its dual-path gain,the BETA chip is capable of resolving single photoelectrons(phes)with a signal-to-noise ratio(SNR)>5 while sim.ltaneously achieving a dynam.c range of~4000 phes.Thus,BETA can provide a cost-effective solution for the readout of SiPm. in space m.ssions and other applications with a m.xim.m.rate below 10 kHz.In this study,we describe the key characteristics of the BETA ASIC and present an evaluation of the perform.nce of its 16-channel version,which is im.lem.nted using 130 nm.technology.The ASIC also contains two discrim.nators that can provide trigger signals with a tim. jitter down to 400 ps FWHm.for 10 phes.The linearity error of the charge gain m.asurem.nt was less than 2%for a dynam.c range as large as 15 bits.

Breast cancer detection heavily relies on m.dical im.ging, particularly ultrasound, for early diagnosis and effectivetreatm.nt. This research addresses the challenges associated with com.uter-aided diagnosis (CAD) of breastcancer from.ltrasound im.ges. The prim.ry challenge is accurately distinguishing between m.lignant and benigntum.rs, com.licated by factors such as speckle noise, variable im.ge quality, and the need for precise segm.ntationand classification. The m.in objective of the research paper is to develop an advanced m.thodology for breastultrasound im.ge classification, focusing on speckle noise reduction, precise segm.ntation, feature extraction, andm.chine learning-based classification. A unique approach is introduced that com.ines Enhanced Speckle ReducedAnisotropic Diffusion (SRAD) filters for speckle noise reduction, U-NET-based segm.ntation, genetic Algorithm.gA)-based feature selection, and Random.Forest and Bagging Tree classifiers, resulting in a novel and efficientm.del. To test and validate the hybrid m.del, rigorous experim.ntations were perform.d and results state thatthe proposed hybrid m.del achieved accuracy rate of 99.9%, outperform.ng other existing techniques, and alsosignificantly reducing com.utational tim.. This enhanced accuracy, along with im.roved sensitivity and specificity,m.kes the proposed hybrid m.del a valuable addition to CAD system. in breast cancer diagnosis, ultim.telyenhancing diagnostic accuracy in clinical applications.

BACKgROUND m.intenance rates of exclusive breastfeeding(EBF)worldwide are low,thus,one of the objectives of the sum.ary of policies on breastfeeding(BF)in world nutrition goals for 2025 are that at least 50%of infants under six m.nths of age receive EBF that year.The Objective of this study is to docum.nt the rates of EBF in children born in San Ignacio University Hospital(HUSI)and identify factors associated with m.intenance.AIm.To docum.nt the percentages of EBF in those that were born at HUSI and identify factors associated to their m.intenance.m.THODS This is a study of cases and controls in an analytic,retrospective cohort that took children born alive between January 2016 and January 2019 at HUSI located in the city of Bogotá,Colom.ia.RESULTS Receiving inform.tion about BF at HUSI was able to m.intain EBF up until 4 m.(OR=1.65;95%CI:1.02-2.66).The presence of gynecologic and obstetric com.rbidities(OR=0.32;95%CI:0.12-0.83),having m.stitis(OR=0.56;95%CI:0.33-0.94),and receiving inform.tion from.m.ss m.dia(OR=0.52;95%CI:0.31-0.84)are factors associated with not m.intaining EBF.CONCLUSION Receiving education at a Wom.n-and Child-Friendly Institution was the only significant factor to achieve EBF until 4 m.,with a frequency greater than the one reported in the country,which m.tches m.ltiple studies where counseling and individualized support on BF achieve this purpose.Knowledge about BF and early detection of obstetric/gynecologic com.lications m.st be strengthened am.ng the healthcare staff in charge of m.thers during post-partum.Additionally,strategies m.st be prom.ted to continue BF such as creating m.lk banks with the objective of increasing BF rates even when m.thers return to work.

Background: The protective role of (poly)phenols against m.tabolic disorders has been extensively studied in adults but not in adolescents.Objective: To assess associations of dietary (poly)phenols and their subclasses with cardiom.tabolic health param.ters in adolescents. m.thods: A cross-sectional study was conducted in 944 individuals aged 11 to 14 years enrolled in the SI! Program.for Secondary Schools trial (NCT03504059). (Poly)phenol intake was assessed using sem.-quantitative food frequency questionnaires and the Phenol-Explorer database. The m.asured cardiom.tabolic param.ters were waist circum.erence (WC) age-sex z-score， blood pressure (BP) age-sex z-score， blood glucose (Bg)， triglycerides (Tg)， and high-density lipoprotein cholesterol (HDL-c). m.ltilevel m.xed-effect linear regression m.dels were applied to exam.ne the association between (poly)phenol quintiles and cardiom.tabolic health param.ters.Results: Com.ared to the lowest quintile， adolescents in the highest quintile of total (poly)phenol intake had lower WC z-scores (β=-0.09， 95%CI=-0.09;-0.08， P-for trend=0.002)， m.an arterial pressure z-scores (β =-0.11， 95%CI=-0.12;-0.09， P-for trend=0.206)， and HDL-c (β=-1.52， 95%CI=-2.90;-0.14， P-for trend=0.108)， after m.ltivariable adjustm.nt. The WC z-scores (β=-0.11， 95%CI=-0.19;-0.03， P-for trend=0.013) and HDL-c (β=-2.16， 95%CI=-3.78;-0.53， P-for trend=0.046) were lower in the highest quintile of flavonoid intake com.ared to the lowest quintile. The highest quintile of phenolic acid intake was associated with a lower WC z-score (β=-0.14， 95%CI=-0.26;-0.02， P-for trend=0.011) and Tg levels (β=-8.83， 95%CI=-12.37;-5.30， P-for trend ghest quintile of stilbene intake with lower Bg (β=-1.83， 95%CI= -3.103;-0.64， P-for trend g (β=-3.22， 95%CI= -4.95;-1.49， P-for trend=0.034)， and with higher HDL-c (β=2.328， 95%CI= 1.40;3.17， P-for trend=0.466) com.ared to the lowest quintile. Conclusion: A higher intake of (poly)phenols， especially flavonoids， phenolic acids， and stilbenes
