Religion and Measles Vaccination in Indonesia, 1991-2017

INTRODUCTION: Some Muslim religious councils in Indonesia have ruled that measles vaccines contain haram (i.e., forbidden materials). This study evaluates the changes in measles vaccination coverage between 1991 and 2017 and compares vaccination coverage between Muslims and non-Muslims in Indonesia. METHODS: A total of 7 cross-sectional in-person surveys of mothers in 1991-2017 in Indonesia were analyzed in 2019. Participants were asked about religion in 1991-2007, and 100 data sets of religion were imputed for 2012 and 2017. In this multiple imputation analysis, binomial regression models output prevalence differences adjusted for wealth, education, child\u27s sex, and mother\u27s age. A quadratic term for year (year X year) and an interaction term between year and religion evaluated changes in vaccination over time by religion. RESULTS: The 7 data sets included 23,106 children aged 12-23 months, with the proportion of those who were Muslims ranging between 85% and 89% across the survey years. Between 1991 and 2017, measles vaccination coverage increased from 57% to 79% among non-Muslims and from 59% to 79% among Muslims. In the multivariable regression model, measles vaccination coverage increased by 1.6% each year (with a quadratic term of -0.05%, indicating some leveling over time). At baseline in 1991, non-Muslims had a vaccination coverage of 6.2% higher than that of Muslims, but this disparity decreased by -0.2% each year. CONCLUSIONS: Measles vaccination increased in both Muslims and non-Muslims in Indonesia but has stagnated in recent years. Because of increased attention among Muslim groups on haram materials in vaccines since 2017, future studies should continue to examine the relationship between religion and vaccine uptake in Indonesia.

Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb$^{-1}$. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages

Study of the B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} decay

The decay $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ is studied in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$ TeV using data corresponding to an integrated luminosity of 5 $\mathrm{fb}^{-1}$ collected by the LHCb experiment. In the $\Lambda_{c}^+ K^{-}$ system, the $\Xi_{c}(2930)^{0}$ state observed at the BaBar and Belle experiments is resolved into two narrower states, $\Xi_{c}(2923)^{0}$ and $\Xi_{c}(2939)^{0}$, whose masses and widths are measured to be $$m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV},$$ where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt $\Lambda_{c}^{+} K^{-}$ sample. Evidence of a new $\Xi_{c}(2880)^{0}$ state is found with a local significance of $3.8\,\sigma$, whose mass and width are measured to be $2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV}$ and $12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}$, respectively. In addition, evidence of a new decay mode $\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-}$ is found with a significance of $3.7\,\sigma$. The relative branching fraction of $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ with respect to the $B^{-} \to D^{+} D^{-} K^{-}$ decay is measured to be $2.36 \pm 0.11 \pm 0.22 \pm 0.25$, where the first uncertainty is statistical, the second systematic and the third originates from the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-028.html (LHCb public pages

Measurement of the ratios of branching fractions R(D∗)\mathcal{R}(D^{*}) and R(D0)\mathcal{R}(D^{0})

The ratios of branching fractions $\mathcal{R}(D^{*})\equiv\mathcal{B}(\bar{B}\to D^{*}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(\bar{B}\to D^{*}\mu^{-}\bar{\nu}_{\mu})$ and $\mathcal{R}(D^{0})\equiv\mathcal{B}(B^{-}\to D^{0}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(B^{-}\to D^{0}\mu^{-}\bar{\nu}_{\mu})$ are measured, assuming isospin symmetry, using a sample of proton-proton collision data corresponding to 3.0 fb${ }^{-1}$ of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode $\tau^{-}\to\mu^{-}\nu_{\tau}\bar{\nu}_{\mu}$. The measured values are $\mathcal{R}(D^{*})=0.281\pm0.018\pm0.024$ and $\mathcal{R}(D^{0})=0.441\pm0.060\pm0.066$, where the first uncertainty is statistical and the second is systematic. The correlation between these measurements is $\rho=-0.43$. Results are consistent with the current average of these quantities and are at a combined 1.9 standard deviations from the predictions based on lepton flavor universality in the Standard Model.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-039.html (LHCb public pages

Effects of Chronic Alcohol Exposure on Use of Incentive Value and Contribution of Central Amygdala

Chronic, high-level exposure to alcohol is associated with deficits in adaptive behavior, or the ability to flexibly adjust actions to achieve desirable outcomes. Such deficits can broadly impact quality of life, for instance by perpetuating alcohol consumption despite increasingly negative consequences. However, the specific components of adaptive behavior that are disrupted following chronic alcohol exposure are not entirely clear. One aspect that may be affected is the ability to use the incentive value – essentially, the subjective attractiveness – of possible outcomes to guide actions. This dissertation examines this possibility across two tasks crucially dependent on the use of incentive value, and investigates the contribution of central amygdala (CeA), a brain region implicated in incentive processes. Chapter 1 examined the ability of mice previously exposed to chronic alcohol to update and use incentive value of food following a shift in motivational state. Results found alcohol mice were impaired following a mild shift in motivation but less so following a large shift, suggesting that deficits could be largely overcome with a salient enough motivational change. Chapter 2 examined the effect of incentive food cues on the actions of mice with a history of chronic alcohol exposure. Results found that the behavior of alcohol mice was subject to greater control by incentive cues, suggesting that the use of incentive value was enhanced in these animals. Chapter 3 examined this same cue-guided behavior during manipulation of CeA activity. Results suggested that alcohol enhancements in cue-guided behavior were countered by excitatory manipulation of CeA, but that CeA manipulation had opposite behavioral effects in alcohol-naïve mice. Together, these studies support that chronic alcohol exposure may enhance the use of incentive value in some circumstances but impair that ability in others, depending on crucial task features. Further, these findings suggest that a nuanced combination of major theories of addiction, such as the negative reinforcement and habit hypotheses, may be warranted. Greater understanding of how chronic alcohol exposure can impact behavior and the brain may prove useful in developing improved assessments and treatments for chronic alcohol use and alcohol use disorder in humans
