    Efficiency Evaluation of Single and Double Tuned Mass Dampers on Building Response Reduction by Considering Soil-Structure Interaction
    (Springer Nature, 2024) Roozbahan,M.; Turan,G.
    Tuned mass dampers (TMDs) and multiple tuned mass dampers (MTMDs) are among the simplest, most reliable, and most frequently employed structural control devices. The efficiency of TMDs and MTMDs depends on their parameters, including the mass, frequency ratio, and damping ratio. Several analytical and metaheuristic methods have been proposed for the optimal design of tuned mass dampers. The aims of this study are: (1) to investigate the differences in efficiency between a number of TMD design methods and (2) to evaluate the differences in efficiency between a single TMD and double TMD (DTMD) in reducing the seismic response of structures by considering soil-structure interactions (SSI). In the first numerical study, the effectiveness of TMDs optimized using seven analytical methods, and TMD and DTMD optimized using a metaheuristics algorithm called Mouth Brooding Fish (MBF) in reducing the response of a fifteen-story structure under 22 far-field and 14 near-field earthquakes is compared. In the second example, in addition to the seven analytical-based designed TMDs, and MBF-based TMDs and DTMDs, the Jaya algorithm based, and plasma generation optimization-based designed TMDs are used, and the same procedure is applied to a forty-story structure. The results show that there is no important difference among these methods, which may indicate that the uppermost optimization level for a regular TMD has been reached. Furthermore, the results indicate that the TMD and DTMD are almost equally effective at reducing the seismic response of structures when the SSI effect is taken into consideration. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

    Recovery of Metals From Leach Liquors: Biosorption Versus Metal Sulfide Precipitation
    (Springer Nature, 2024) Kucuker,M.A.
    Extraction of metals (leaching) is chemical or biochemical processes that utilize acids or microorganisms to enhance the suspension of metals from the primary and secondary sources by making them more amenable to dissolution in aqueous solutions (leachate). Recovery of metals from the leachates is an essential stage supported by additional purification processes such as precipitation of impurities, electrowinning, solvent extraction, chemical or biological adsorption, and ion exchange. In this study, especially biosorption and metal sulfide precipitation are overviewed and discussed. Biosorption is a process by which particular biomass such as bacteria, fungi, yeast, agricultural wastes, algae, and biowastes can able to bind with specific ions or other molecules from aqueous solutions. Metal sulfide precipitation can be highly effective in obtaining a high degree of separation of metal cations from complex leachates. Each of these techniques has advantages and drawbacks. Sometimes, a technique may not be effective in attaining higher metal recovery. Therefore, different recovery techniques are needed to recover the target elements from the complex leachates. Maybe a combination of two or three recovery techniques is required to recover metals from complex leachates. Additionally, the research activity highlighted that metal sulfide precipitation and biosorption processes have to limit factors that could hinder the process scale-up. Thus, more research is needed to evaluate the environmental impacts of metal recovery from leach liquors. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

    Tomato: Genetics, Genomics, and Breeding of Health-Related Traits
    (Springer Nature, 2023) Çelik,I.; Gürbüz Çolak,N.; Doğanlar,S.; Frary,A.
    Tomato (Solanum lycopersicum) is a popular crop due to its versatility and nutritional quality. In addition to its nutritional content, tomato is rich in various phytochemicals that are known to have beneficial effects on human health. These bioactive components include pigments like lycopene and Β-carotene, ascorbic acid (vitamin C), phenolic compounds, polyamines, and glycoalkaloids. Tomato metabolites have various bioactivities such as antihypertensive, antioxidant, anticancer, anti-inflammatory, antidiabetic, antiallergenic, antiatherogenic, antithrombotic, and antimicrobial effects. Research aimed at improving tomato for many of these specific activities is still in its infancy; however, a foundation of knowledge has been established for health-related (HR) traits in the crop. In this chapter, previous works surveying tomato germplasm for HR traits, conventional breeding, and genetic investigation of these characteristics are described. We also discuss research aimed at HR gene mapping and isolation as well as efforts to improve these traits via genetic engineering and genome editing. © Springer Nature Singapore Pte Ltd. 2023.

    Avant-Garde Hydrogels as Stem Cell Niche for Cardiovascular Regenerative Medicine
    (Springer Nature, 2023) Yilmaz,H.D.; Arslan,Y.E.
    Cardiovascular diseases remain the primary cause of death in the modern world. According to the World Health Organization (WHO), almost 18 million people lose their lives each year due to cardiac dysfunction. Nearly 75% of the cases are related to heart attack, stroke, and heart failure. Furthermore, the limited restoration capacity of the adult cardiac tissue leads to irreversible changes in myocardial injury and ischemia, which seriously increases the mortality rates. Currently, the available therapeutic approaches for cardiovascular dysfunctions mainly depend on pharmaceutical drugs, vascular assist devices, or organ transplantations in severe cases. However, these strategies cannot prevent ischemia-related damages or restore the dysfunction of heart tissue. Besides, there are certain limitations, including donor shortage, thrombosis of the device, immune rejection reactions, and operative morbidity of the patient. Therefore, combining stem cells with outstanding hydrogels has become a critically important phenomenon in treating cardiovascular disease. Today, stem cell-based applications form the pivot point of regenerative treatments due to their differentiation and immunomodulatory capacity. However, due to low cellular retention and the inhomogeneous therapeutic activities, the effectiveness of stem cell regeneration in clinical and preclinical studies is reduced. Hence, the synergetic approaches of the injectable hydrogels with stem cells and subcellular bioactive tools may hold the promises of the next-generation therapies. Over the last decade, various functional hydrogels from natural, synthetic, or decellularized tissue precursors have been developed and investigated for cardiovascular applications. In this chapter, advances in stem cell therapy have been discussed with the latest research on functional hydrogels for cardiovascular regeneration. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

    Degraded Arid Soil Reclamation for Cotton Cultivation Using Organic Waste Amendments
    (Springer Nature, 2024) Kogbara,R.; Hamdi,H.; Al-Sharshani,A.; Abdalla,O.; Onwusogh,U.; Solim,S.
    Qatar is one of the most fertilizer-dependent countries due to challenging soil and climatic conditions. The country strives toward self-sufficiency in agricultural production in alignment with the Qatar National Vision 2030. Hence, this work investigates the potential of utilizing nutrient-rich resources that are currently wasted for the reclamation of degraded arid soils to support the cultivation of industrial crops such as cotton (Gossypium spp.). Two abundant organic wastes, industrial biosludge and cow dung compost, were employed as soil amendments at a 3% application rate on a silty loam soil with relatively high salinity (electrical conductivity = 5.60 dS/m) and compared with conventional chemical fertilization. Cotton (May 344 variety) was then grown on the biowaste-amended soils in lysimeters for ten months (March through January) spanning through the hot season in Qatar, with the average temperature ranging from 19 to 37 °C. Soil properties and plant growth characteristics, including soil metal concentrations, days to germination and flowering, plant height, and cotton yield, were determined at set periods. The results indicated that different from the chemical fertilizer treatment, the organic amendments led to a significant release of potassium eight months after planting, roughly twice the concentration available at the initial sampling period. In all treatments, soil magnesium and iron concentrations generally increased, while phosphorus and zinc decreased over time. There was generally no significant difference in the concentrations of metals analyzed such as chromium, copper, nickel, and zinc between soils amended with the organic wastes and chemical fertilizer. The concentrations of metals were below the regulatory limits for sewage sludge applied to soils. The days to germination were 2, 9, and 11, while the days to flowering were 61, 92, and 77 for the cow dung compost, biosludge, and fertilizer treatments, respectively. The average cumulative plant heights were 74, 65, and 63 cm, while the average cumulative cotton boll yield was 7.3, 5.4, and 2.6 tons/ha, respectively, in the cow dung compost, biosludge, and fertilizer treatments. The results demonstrate that the organic amendments, especially cow dung compost, can help reclamation of degraded/saline arid soils under the described pedo-climatic conditions. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

    Precise Determination of the Mass of the Higgs Boson and Tests of Compatibility of Its Couplings With the Standard Model Predictions Using Proton Collisions at 7 and 8 Tev
    (Springer Nature, 2015) Khachatryan, V.; Sirunyan, A.M.; Tumasyan, A.; Adam, W.; Bergauer, T.; Dragicevic, M.; Janot, P.
    Properties of the Higgs boson with mass near 125 GeV are measured in proton-proton collisions with the CMS experiment at the LHC. Comprehensive sets of production and decay measurements are combined. The decay channels include γγ, ZZ, WW, ττ, bb, and μμ pairs. The data samples were collected in 2011 and 2012 and correspond to integrated luminosities of up to 5.1fb-1at 7TeV and up to 19.7fb-1at 8 TeV. From the high-resolution γγ and ZZ channels, the mass of the Higgs boson is determined to be (Formula presented) GeV. For this mass value, the event yields obtained in the different analyses tagging specific decay channels and production mechanisms are consistent with those expected for the standard model Higgs boson. The combined best-fit signal relative to the standard model expectation is (Formula presented) at the measured mass. The couplings of the Higgs boson are probed for deviations in magnitude from the standard model predictions in multiple ways, including searches for invisible and undetected decays. No significant deviations are found. © 2015, CERN for the benefit of the CMS collaboration.

    Search for New Physics in Same-Sign Dilepton Events in Proton–proton Collisions at √s = 13 Tev
    (Springer Nature, 2016) Khachatryan, V.; Sirunyan, A.M.; Tumasyan, A.; Adam, W.; Asilar, E.; Bergauer, T.; Scodellaro, L.
    A search for new physics is performed using events with two isolated same-sign leptons, two or more jets, and missing transverse momentum. The results are based on a sample of proton–proton collisions at a center-of-mass energy of 13TeV recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of 2.3 fb1. Multiple search regions are defined by classifying events in terms of missing transverse momentum, the scalar sum of jet transverse momenta, the transverse mass associated with a W boson candidate, the number of jets, the number of b quark jets, and the transverse momenta of the leptons in the event. The analysis is sensitive to a wide variety of possible signals beyond the standard model. No excess above the standard model background expectation is observed. Constraints are set on various supersymmetric models, with gluinos and bottom squarks excluded for masses up to 1300 and 680GeV, respectively, at the 95 % confidence level. Upper limits on the cross sections for the production of two top quark-antiquark pairs (119fb) and two same-sign top quarks (1.7pb) are also obtained. Selection efficiencies and model independent limits are provided to allow further interpretations of the results. © 2016, CERN for the benefit of the CMS collaboration.

    Measurement of the W +w - Cross Section in Pp Collisions at √s= 8 Tevand Limits on Anomalous Gauge Couplings
    (Springer Nature, 2016) Khachatryan, V.; Sirunyan, A.M.; Tumasyan, A.; Adam, W.; Asilar, E.; Bergauer, T.; Albajar, C.
    A measurement of the W boson pair production cross section in proton-proton collisions at √s = 8 TeV is presented. The data collected with the CMS detector at the LHC correspond to an integrated luminosity of 19.4fb-1. The W +W - candidates are selected from events with two charged leptons, electrons or muons, and large missing transverse energy. The measured W +W - cross section is 60.1 ± 0.9 (stat) ± 3.2 (exp) ± 3.1 (theo) ± 1.6 (lumi) pb = 60.1±4.8 pb, consistent with the standard model prediction. The W +W - cross sections are also measured in two different fiducial phase space regions. The normalized differential cross section is measured as a function of kinematic variables of the final-state charged leptons and compared with several perturbative QCD predictions. Limits on anomalous gauge couplings associated with dimension-six operators are also given in the framework of an effective field theory. The corresponding 95 % confidence level intervals are -5.7<cWWW/Λ2<5.9TeV-2, -11.4<cW/Λ2<5.4TeV-2, -29.2<cB/Λ2<23.9TeV-2, in the HISZ basis. © 2016, CERN for the benefit of the CMS collaboration.

    Measurement of the Double-Differential Inclusive Jet Cross Section in Proton–proton Collisions at √s = 13 Tev
    (Springer Nature, 2016) Khachatryan, V.; Sirunyan, A.M.; Tumasyan, A.; Adam, W.; Asilar, E.; Bergauer, T.; Matorras, F.
    A measurement of the double-differential inclusive jet cross section as a function of jet transverse momentum pT and absolute jet rapidity | y| is presented. The analysis is based on proton–proton collisions collected by the CMS experiment at the LHC at a centre-of-mass energy of 13TeV. The data samples correspond to integrated luminosities of 71 and 44pb-1 for | y| < 3 and 3.2 < | y| < 4.7 , respectively. Jets are reconstructed with the anti-kt clustering algorithm for two jet sizes, R, of 0.7 and 0.4, in a phase space region covering jet pT up to 2TeV and jet rapidity up to | y| = 4.7. Predictions of perturbative quantum chromodynamics at next-to-leading order precision, complemented with electroweak and nonperturbative corrections, are used to compute the absolute scale and the shape of the inclusive jet cross section. The cross section difference in R, when going to a smaller jet size of 0.4, is best described by Monte Carlo event generators with next-to-leading order predictions matched to parton showering, hadronisation, and multiparton interactions. In the phase space accessible with the new data, this measurement provides a first indication that jet physics is as well understood at s=13TeV as at smaller centre-of-mass energies. © 2016, CERN for the benefit of the CMS collaboration.

    Measurement of Inclusive Jet Production and Nuclear Modifications in Ppb Collisions at √snn = 5.02 Tev
    (Springer Nature, 2016) Khachatryan,V.; Sirunyan,A.M.; Tumasyan,A.; Adam,W.; Asilar,E.; Bergauer,T.; Fernandez,M.
    Inclusive jet production in pPb collisions at a nucleon–nucleon (NN) center-of-mass energy of √sNN= 5.02TeV is studied with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 30.1 nb- 1 is analyzed. The jet transverse momentum spectra are studied in seven pseudorapidity intervals covering the range - 2.0 < ηCM< 1.5 in the NN center-of-mass frame. The jet production yields at forward and backward pseudorapidity are compared and no significant asymmetry about ηCM= 0 is observed in the measured kinematic range. The measurements in the pPb system are compared to reference jet spectra obtained by extrapolation from previous measurements in pp collisions at √s=7TeV. In all pseudorapidity ranges, nuclear modifications in inclusive jet production are found to be small, as predicted by next-to-leading order perturbative QCD calculations that incorporate nuclear effects in the parton distribution functions. © 2016, CERN for the benefit of the CMS collaboration.
