    Metareferentiality through in-game images in immersive simulation games

    Digital games have a tenuous relationship to reality; in most cases, they are rather simulacra than simulations, offering a simulation-like situation that does not relate to any preceding reality but creates a virtual world precedented only in other fictional or virtual works. The visuals of mainstream, Triple-A games counteract this ontological disconnect through an overabundance of detail and flourish in a perennial struggle for verisimilitude. This paper discusses two examples which, while generally adhering to this convention, introduce elements of subversion into their visual logic. It will show that there are various metaleptic ludic devices - such as virtual reality environments within virtual worlds and reality-changing paintings - with which contemporary digital games reflect subtly upon their own relationship to reality, and upon the player's oscillation between agency and powerlessness

    Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

    A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

    Chromosome Xq23 is associated with lower atherogenic lipid concentrations and favorable cardiometabolic indices

    AbstractAutosomal genetic analyses of blood lipids have yielded key insights for coronary heart disease (CHD). However, X chromosome genetic variation is understudied for blood lipids in large sample sizes. We now analyze genetic and blood lipid data in a high-coverage whole X chromosome sequencing study of 65,322 multi-ancestry participants and perform replication among 456,893 European participants. Common alleles on chromosome Xq23 are strongly associated with reduced total cholesterol, LDL cholesterol, and triglycerides (min P = 8.5 × 10−72), with similar effects for males and females. Chromosome Xq23 lipid-lowering alleles are associated with reduced odds for CHD among 42,545 cases and 591,247 controls (P = 1.7 × 10−4), and reduced odds for diabetes mellitus type 2 among 54,095 cases and 573,885 controls (P = 1.4 × 10−5). Although we observe an association with increased BMI, waist-to-hip ratio adjusted for BMI is reduced, bioimpedance analyses indicate increased gluteofemoral fat, and abdominal MRI analyses indicate reduced visceral adiposity. Co-localization analyses strongly correlate increased CHRDL1 gene expression, particularly in adipose tissue, with reduced concentrations of blood lipids.Abstract Autosomal genetic analyses of blood lipids have yielded key insights for coronary heart disease (CHD).

    Meta-analysis of genome-wide association studies discovers multiple loci for chronic lymphocytic leukemia.

    Chronic lymphocytic leukemia (CLL) is a common lymphoid malignancy with strong heritability. To further understand the genetic susceptibility for CLL and identify common loci associated with risk, we conducted a meta-analysis of four genome-wide association studies (GWAS) composed of 3,100 cases and 7,667 controls with follow-up replication in 1,958 cases and 5,530 controls. Here we report three new loci at 3p24.1 (rs9880772, EOMES, P=2.55 × 10(-11)), 6p25.2 (rs73718779, SERPINB6, P=1.97 × 10(-8)) and 3q28 (rs9815073, LPP, P=3.62 × 10(-8)), as well as a new independent SNP at the known 2q13 locus (rs9308731, BCL2L11, P=1.00 × 10(-11)) in the combined analysis. We find suggestive evidence (P<5 × 10(-7)) for two additional new loci at 4q24 (rs10028805, BANK1, P=7.19 × 10(-8)) and 3p22.2 (rs1274963, CSRNP1, P=2.12 × 10(-7)). Pathway analyses of new and known CLL loci consistently show a strong role for apoptosis, providing further evidence for the importance of this biological pathway in CLL susceptibility

    Search for standard model production of four top quarks in proton–proton collisions at

    A search for events containing four top quarks (t¯tt¯t) is reported from proton–proton collisions recorded by the CMS experiment at √s=13TeVand corresponding to an integrated luminosity of 2.6fb−1. The analysis considers the single-lepton (e or μ)+jets and the opposite-sign dilepton (μ+μ−, μ±e∓, or e+e−)+jets channels. It uses boosted decision trees to combine information on the global event and jet properties to distinguish between t¯tt¯tand t¯tproduction. The number of events observed after all selection requirements is consistent with expectations from background and standard model signal predictions, and an upper limit is set on the cross section for t¯tt¯tproduction in the standard model of 94fb at 95% confidence level (10.2×the prediction), with an expected limit of 118fb. This is combined with the results from the published CMS search in the same-sign dilepton channel, resulting in an improved limit of 69fb at 95% confidence level (7.4×the prediction), with an expected limit of 71fb. These are the strongest constraints on the rate of t¯tt¯tproduction to date.We congratulate our colleagues in the CERN accelerator depart-ments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS in-stitutes for their contributions to the success of the CMS effort.
