description: In this paper, we give a systematic theoretical study on the Landau levels (LLs) and magneto-optical conductivity Re$(σ_{αα})$ in a gapped Dirac semimetal model with mixed linear and parabolic dispersions under a magnetic field, which was recently proposed by Jiang \textit{et al.} [Phys. Rev. Lett. {\bf125}, 046403 (2020)] to explain the experimental magnetoinfrared spectroscopy in the three-dimensional ZrTe$_5$ crystal. We find that the strong magnetic field can drive the LLs become noninverted and thus the strong topological insulator phase in ZrTe$_5$ turns to be a trivial insulator. In the different magnetic field regions, the density of states and Re$(σ_{αα})$ can exhibit distinct signatures. Moreover, when the magnetic field is weak, a qualitative relation in Re$(σ_{zz})$ between the peaks at the saddle points is revealed as Re$(σ_{zz}^{ζ_n})>$Re$(σ_{zz}^Γ)$, which is in good agreement with the experiment.

description: Based on density functional theory (DFT), we performed first-principle studies on the electronic structure, magnetic state and optical properties of two-dimensional (2D) transition-metal phosphorous trichalcogenide MnPX$_3$ (X=S and Se). The calculated interlayer cleavage energies of MnPX$_3$ monolayers indicate the energetic possibility to be exfoliated from bulk phase, with good dynamical stability confirmed by the absence of the imaginary contributions in the phonon spectra. MnPX$_3$ monolayers are both Néel antiferromagnetic (AFM) semiconductors with direct band gaps falling into the visible optical spectrum. Magnetic interaction parameters were extracted within the Heisenberg model to investigate the origin of the AFM state. Three in-plane magnetic exchange parameters play important role in the robust AFM configuration of Mn ions. The Néel temperatures ($T_\mathrm{N}$) were estimated by means of Monte Carlo simulations, obtaining the theoretical $T_\mathrm{N}$ of $103$\,K and $80$\,K for 2D MnPS$_3$ and MnPSe$_3$, respectively. With high spin state, Mn ions arranged in honeycomb lattices, the spin-degenerated band structures exhibit valley polarisation and was investigated in different biaxial in-plain strains, considering the spin-orbital coupling (SOC). 2D MnPX$_3$ monolayers show excellent performance on the optical properties, and the absorption spectra were discussed in detail to find the transition mechanism. Different amount and configuration of chalcogen vacancy were introduced into the MnPX$_3$ monolayers, and it is found that the electronic structures are heavily affected depending on the vacancy geometric structure, leading to different magnetic state and absorption spectra of defected MnPX$_3$ systems.

description: Mitral Valve Transcatheter Edge-to-Edge Repair (M-TEER) is a minimally invasive procedure for patients with symptomatic mitral regurgitation. Its outcomes in patients with a history of coronary artery bypass grafting (CABG) remain unclear. We analyzed data from the Nationwide Inpatient Sample, using ICD-10-CM codes for M-TEER and CABG. Primary outcomes included in-hospital all-cause mortality and periprocedural cardiac complications. Inverse probability of treatment weighting was employed to compare M-TEER patients with or without prior CABG. From January 2016 to December 2020, we identified 48,835 M-TEER cases in the U.S. with 9,655 patients (19.78%) having a prior CABG. These patients were older and had more comorbidities. M-TEER procedures increased over the study period, including those with prior CABG (2,145 in 2016 vs. 2,682 in 2020). Adjusted analysis showed no significant difference in in-hospital mortality between patients with and without prior CABG [adjusted odds ratio (aOR) 0.85, 95% confidence interval (CI) 0.85–1.32, p = 0.47]. However, patients with prior CABG had lower odds of periprocedural cardiac complications [aOR 0.72, 95% CI 0.59–0.87, p = 0.001]. M-TEER appears safe for patients with prior CABG, showing no adverse peri-procedural outcomes compared to those without CABG. Despite more comorbidities, M-TEER remains a safe option for these patients.

description: Propagation of waves through Cantor-set media is investigated by renormalization-group analysis. For specific values of wave numbers, transmission coefficients are shown to be governed by the logistic map, and in the chaotic region, they show sensitive dependence on small changes of parameters of the system such as the index of refraction. For other values of wave numbers, our numerical results suggest that light transmits completely or reflects completely by the Cantor-set media ${\rm C}_{\infty}$. It is also shown that transmission coefficients exhibit a local scaling behavior near complete transmission if the complete transmission is achieved at a wave number $κ=κ^*$ with a rational $κ^*/π$. The scaling function is obtained analytically by using the Euler's totient function, and the local scaling behavior is confirmed numerically.

description: Recent studies reported on the synthesis and characterization of several bulk crystals of layered metal triselenophosphites MPSe$_3$ (M = transition metals). In these works characterization was performed via a combination of different bulk- and surface-sensitive experimental methods accompanied by DFT calculations. However, the critical examination of the available experimental and theoretical data demonstrates that these results do not support the conclusions on the electrochemical sensing and energy applications of studied triselenophosphites. These conclusions are made without any relation to the age of discussed data and possible recent progress in experimental and theoretical approaches.

description: The method of Taylor series expansion is used to develop a numerical solution to the reactor point kinetics equations. It is shown that taking a first order expansion of the neutron density and precursor concentrations at each time step gives results that are comparable to those obtained using other popular and more complicated methods. The algorithm developed using a Taylor series expansion is simple, completely transparent, and highly accurate. The procedure is tested using a variety of initial conditions and input data, including step reactivity, ramp reactivity, sinusoidal, and zigzag reactivity. These results are compared to those obtained using other methods.

Le Shasekishu : miroir d’une personnalité, miroir d’une époque

Publisher: name: University of British Columbia
Year: 2010

description: Mujû Kokushi was born in 1227, some forty years after the great upheaval caused by the struggle between the Taira and Minamoto families. His was a century of religious controversies which were often the outcome of a search for a form of Buddhism capable of answering the spiritual needs of the masses. Mujû could see no incompatibility between the traditional forms of Buddhism and a truly popular religion. He wrote the Shasekishû in order to demonstrate that every aspect of Buddhism can be practical and useful. For instance, he said that although the practice of Shingon Buddhism is usually thought to be proper only for princes and priests, nowhere in the Scriptures is such an idea stated. Every man or woman, he felt, must avail himself or herself of the miraculous power of the magic formulae of esoteric Buddhism. Mujû did not want to discard all the new schools of buddhist thought which had sprung up during his lifetime, but he deplored their excesses and the narrowness of their views, which bred prejudice and intolerance. This dissertation is composed of two parts of approximately the same length. The first part is an effort to present Mujû points of view through, the study of his life and writings, more specifically of the Shasekishû, a collection of sermons and tales written during the years 1279-84. Mujû's goal is twofold: first, to prove the practicality of Buddhism, its unfailing availability through the compassionate care of many Buddhas and bodhisattvas who vowed to save humanity. Second, to show that the truths of Buddhism are unchangeable, and that differences of opinion are merely different ways of considering the same idea. Therefore, the new sects, such as the Pure Land sect, were grossly mistaken when they claimed to offer the only valid solution to the problems of the time. There is an answer to each individual need, and it is made available through Buddha's universal expedients, or hôben. In Japan , hôben is made tangible in the various native gods or kami, and in the form of poetry called waka, which Mujû regards as the highest expression of Buddha's golden thought and the ultimate means of communion between the Japanese mind and transcendental Truth. For this reason, Mujû equates waka with the magic formulae of esoteric Buddhism or dhâranî. In the Shasekishû, Mujû gives many examples of the application of buddhist ideals in daily life. His humorous approach, the lighter vein of the second part of his book, is perhaps intended to make the revelation of the Truth less formidable. The second part of this dissertation is a selection of translated texts chosen to illustrate the main points of the argument. The text used for this study is edited by Watanabe Tsunaya, Shasekishû , Nihon Koten Bungaku Taikei 85, (Tokyo: Iwanami, 1966).

description: A hole spin is a potential solid-state q-bit, that may be more robust against nuclear spin induced dephasing than an electron spin. Here we propose and demonstrate the sequential preparation, control and detection of a single hole spin trapped on a self-assembled InGaAs/GaAs quantum dot. The dot is embedded in a photodiode structure under an applied electric-field. Fast, triggered, initialization of a hole spin is achieved by creating a spin-polarized electron-hole pair with a picosecond laser pulse, and in an applied electric-field, waiting for the electron to tunnel leaving a spin-polarized hole. Detection of the hole spin with picosecond time resolution is achieved a second picosecond laser pulse to probe the positive trion transition, where a trion is created conditional on the hole spin to be detected as a change in photocurrent. Finally, using this setup we observe a Rabi rotation of the hole-trion transition that is conditional on the hole spin, which for a pulse-area of $2π$ can be used to impart a phase-shift of $π$ between the hole spin states, a non-general manipulation of the hole spin.

description: Any pure quantum state can be equivalently represented by means of its wave function psi(q) or of the Fermi function g_F(q,p), with q and p coordinates and conjugate momenta of the system under investigation.We show that a Gaussian wave packet can be conveniently visualized in phase space by means of the curve g_F(q,p)=0. The evolution in time of the g_F=0 curve is then computed for a Gaussian packet evolving freely or under a constant or a harmonic force. As a result, the spreading or shrinking of the packet is easily interpreted in phase space. Finally, we discuss a gedanken prism microscope experiment for measuring the position-momentum correlation. This gedanken experiment, together with the well-known Heisenberg microscope and von Neumann velocimeter, is sufficient to fully determine the state of a Gaussian packet.

description: This study is the first to provide a systematic review of the literature focused on the relationship between digitalization and organizational agility (OA). It applies the bibliographic coupling method to 171 peer-reviewed contributions published by 30 June 2021. It uses the digitalization perspective to investigate the enablers, barriers and benefits of processes aimed at providing firms with the agility required to effectively face increasingly turbulent environments. Three different, though interconnected, thematic clusters are discovered and analysed, respectively focusing on big-data analytic capabilities as crucial drivers of OA, the relationship between digitalization and agility at a supply chain level, and the role of information technology capabilities in improving OA. By adopting a dynamic capabilities perspective, this study overcomes the traditional view, which mainly considers digital capabilities enablers of OA, rather than as possible outcomes. Our findings reveal that, in addition to being complex, the relationship between digitalization and OA has a bidirectional character. This study also identifies extant research gaps and develops 13 original research propositions on possible future research pathways and new managerial solutions.

description: The generalized Chaplygin gas (GCG) model is the prototype of a unified model of dark energy (DE) and dark matter (DM). It is characterized by equation-of-state (EoS) parameters $A$ and $α$. We use a statistical analysis of the 2dFGRS data to constrain these parameters. In particular, we find that very small (close to zero) and very large values ($α\gg 1$) of the equation-of-state parameter $α$ are preferred. To test the validity of this type of unification of the dark sector we admit the existence of a separate DM component in addition to the Chaplygin gas and calculate the probability distribution for the fractional contributions of both components to the total energy density. This analysis favors a model for which the Universe is nearly entirely made up of the separate DM component with an almost negligible Chaplygin gas part. This confirms the results of a previous Newtonian analysis.

description: Natural fiber reinforced composites are an emerging area in polymer science and future trend applications. These natural fibers are comes with low-cost fibers with superior mechanical properties, low density and high specific properties, biodegradable and non-abrasive nature. These may offer specific properties comparable to those of conventional fiber composites. By applying the fibers in a hybrid form to take the advantage of both natural and synthetic fibers in order to bring out the various attractive properties, which resulted in superior mechanical and tribological properties. Keeping this view, the present work has been under taken to develop a polymer matrix composite (epoxy resin) using Hemp, Basalt, Carbon and E-Glass fibers fabricated by using Hand lay-up technique. Mechanical properties such as tensile, flexural, impact strength and hardness of each composite will be investigated. In order to increase fibre/matrix compatibility and the properties of the natural fibers were treated with the chemical treatments like alkaline and silane treatments. This research aims to synthesize the epoxy hybrid composite by utilizing the hemp (H), basalt (B), carbon fiber (C) and chopped mate E-glass fiber (G) as layering via hand layup techniques. Using above these reinforcements' C1 H/B/G/C (hybrid), C2 B/G/H, C3 B/H/G, C4 G/H/C, C5 B/H/G five different combinations have been developed as per ASTM standards and mechanical testings' such as tensile, flexural, impact, and hardness is carried out. From the test results, it was found that the C1 H/B/G/C sample exhibits the maximum tensile strength and flexural strength of 365.61 MPa and 820.31 MPa at the ultimate loads of 28.664KN and 2.5KN and impact strength of 26J which was maximum compared with other samples C2, C3, C4, C5

description: The paper presents a longitudinal analysis of the evolution of new physics keywords co-occurrence patterns. For that, we explore the documents indexed in the INSPIRE database from 1989 to 2018. Our purpose is to quantify the knowledge structure of the fast-growing subfield of new physics. The development of a novel approach to keywords co-occurrence analysis is the main point of the paper. In contrast to traditional co-keyword network analysis, we investigate structures that unite physics concepts in different documents and bind different documents with the same physics concepts. We consider the structures that reveal relationships among concepts as topological and call them "physics senses". Based on the notion of trajectory mutual information, the paper offers clustering of physics senses, determines their period of life, and constructs a classification of senses' "authority".

description: We conducted a comprehensive study on the shell structure of the Cygnus Loop using 41 observation data obtained by the Suzaku and the XMM-Newton satellites. To investigate the detailed plasma structure of the Cygnus Loop, we divided our fields of view into 1042 box regions. From the spectral analysis, the spectra obtained from the limb of the Loop are well fitted by the single-component non-equilibrium ionization plasma model. On the other hand, the spectra obtained from the inner regions are well fitted by the two-component model. As a result, we confirmed that the low-temperature and the high-temperature components originated from the surrounding interstellar matter (ISM) and the ejecta of the Loop, respectively. From the best-fit results, we showed a flux distribution of the ISM component. The distribution clearly shows the limb-brightening structure, and we found out some low-flux regions. Among them, the south blowout region has the lowest flux. We also found other large low-flux regions at slightly west and the northeast from the center. We estimated the former thin shell region to be 1.3 degrees in diameter and concluded that there exists a blowout along the line of sight in addition to the south blowout. We also calculated the emission measure distribution of the ISM component and showed that the Cygnus Loop is far from the result obtained by a simple Sedov evolution model. From the results, we support that the Cygnus Loop originated from a cavity explosion. The emission measure distribution also suggests that the cavity-wall density is higher in the northeast than that in the southwest. These results suggest that the thickness of the cavity wall surrounding the Cygnus Loop is not uniform.

description: We study the holographic D3/D7 setup dual to N=4 supersymmetric Yang-Mills with quenched fundamental matter. We extend the previous analyses of conductivity and photoproduction to the case where there is a finite electric field. Due to the electric field a special region in the D7-brane geometry, labelled the singular shell, appears generically, and the computation of correlators involves a careful study of the indicial exponents both at this singular region and at the horizon. We show that there is a unique choice consistent with the known expression for the electrical conductivity found by Karch and O'Bannon. We explore the parameter space spanned by the quark mass, the baryon density and the electric field. We find a region where the conductivity and photoproduction change rapidly and trace this behavior to competing effects which manifest themselves as a crossover behavior in the probe brane embeddings.

description: In this paper we investigate various algorithms for performing Fast Fourier Transformation (FFT)/Inverse Fast Fourier Transformation (IFFT), and proper techniquesfor maximizing the FFT/IFFT execution speed, such as pipelining or parallel processing, and use of memory structures with pre-computed values (look up tables -LUT) or other dedicated hardware components (usually multipliers). Furthermore, we discuss the optimal hardware architectures that best apply to various FFT/IFFT algorithms, along with their abilities to exploit parallel processing with minimal data dependences of the FFT/IFFT calculations. An interesting approach that is also considered in this paper is the application of the integrated processing-in-memory Intelligent RAM (IRAM) chip to high speed FFT/IFFT computing. The results of the assessment study emphasize that the execution speed of the FFT/IFFT algorithms is tightly connected to the capabilities of the FFT/IFFT hardware to support the provided parallelism of the given algorithm. Therefore, we suggest that the basic Discrete Fourier Transform (DFT)/Inverse Discrete Fourier Transform (IDFT) can also provide high performances, by utilizing a specialized FFT/IFFT hardware architecture that can exploit the provided parallelism of the DFT/IDF operations. The proposed improvements include simplified multiplications over symbols given in polar coordinate system, using sinе and cosine look up tables,and an approach for performing parallel addition of N input symbols.

description: We report on the first long (~32 ks) pointed XMM-Newton observation of the supergiant fast X-ray transient IGRJ16479-4514. Results from the timing, spectral and spatial analysis of this observation show that the X-ray source IGRJ16479-4514 underwent an episode of sudden obscuration, possibly an X-ray eclipse by the supergiant companion. We also found evidence for a soft X-ray extended halo around the source that is most readily interpreted as due to scattering by dust along the line of sight to IGRJ16479-4514.

description: The electronic and magnetic properties of pristine CrPSe$_3$ and mixed Cr$_{1\textrm{-}x}$M$_x$PSe$_3$ (M = Zn, Cd, Hg) monolayers were studied using density functional theory including an on-site Coulomb term (DFT$+U$) and tight-binding approach (TBA). While pristine CrPSe$_3$ monolayer has an antiferromagnetic (AFM) ground state, its alloying with MPSe$_3$ may give rise to half-metallic ferromagnet (HMF) with high Curie temperature. The resulting monolayers demonstrate single-spin Dirac cones of mainly Cr-$d$ character located in the first Brillouin zone directly at the Fermi energy. The calculated Fermi velocities of Dirac fermions indicate very high mobility in mixed Cr$_{1\textrm{-}x}$M$_x$PSe$_3$ monolayers, that makes this material appealing for low-dimensional spintronics applications.

description: Despite the vast literature on birth-order effects in developing countries, there has been little research on their long-term changes. This study uses three population censuses of Cambodia to investigate how birth order affects educational attainments and how its effects changed over time. We estimate regressions with family fixed effects and cohort fixed effects, and present four findings. First, later-born children are less likely to enroll in primary school and gain literacy skills, and end up with fewer years of schooling than first-born children. Second, controlling for gender differences in education, we find smaller birth-order effects for girls. Third, there is a strong relationship between the gender composition of siblings and birth-order effects. Finally, not only have these birth-order effects attenuated over time but the relationship between the gender composition of siblings and birth-order effects has also changed. In the 1998 census, if the firstborn child is male, his sisters’ educational outcomes are influenced more by their birth order compared with his brothers. In contrast, in the 2019 census, if the firstborn child is male, his sisters' educational outcomes are less susceptible to birth-order effects compared with his brothers. Our findings indicate gendered economic disparities within households and their long-term changes.

description: Context. Outflows powered by the injection of kinetic energy from massive stars can strongly affect the chemical evolution of galaxies, in particular of dwarf galaxies, as their lower gravitational potentials enhance the chance of a galactic wind. Aims. We therefore performed a detailed kinematic analysis of the neutral and ionised gas components in the nearby star-forming irregular dwarf galaxy NGC 4861. Similar to a recently published study of NGC 2366, we want to make predictions about the fate of the gas and to discuss some general issues about this galaxy. Methods. Fabry-Perot interferometric data centred on the Halpha line were obtained with the 1.93m telescope at the Observatoire de Haute-Provence. They were complemented by HI synthesis data from the VLA. We performed a Gaussian decomposition of both the Halpha and the HI emission lines in order to search for multiple components indicating outflowing gas. The expansion velocities of the detected outflows were compared to the escape velocity of NGC 4861, which was modelled with a pseudo-isothermal halo. Results. Both in Halpha and HI the galaxy shows several outflows, three directly connected to the disc and probably forming the edges of a supergiant shell, and one at kpc-distance from the disc. We measured velocity offsets of 20 to 30 km/s, which are low in comparison to the escape velocity of the galaxy and therefore minimise the chance of a galactic wind.

description: As empresas têm investido cada vez mais em maneiras de se aproximar do cliente, a criar um laço mais forte do que simplesmente pela utilidade do produto vendido, além de qualidade e preço justo. Pode-se considerar que a implementação de comunidades de marca é uma das estratégias para gerar o relacionamento mais próximo com seu público de interesse, num ambiente em que os próprios clientes podem interagir com a empresa e os fãs da sua marca. A internet, por si só, aproximou clientes e fãs de marca que, mesmo distantes geograficamente, puderam se conectar através dela. A união desses dois pontos possibilitou a criação de comunidades de marca digitais. Portanto, a investigação objetivou entender se o perfil pessoal de uma influenciadora digital nas redes sociais pode se tornar uma comunidade de marca por meio dos conteúdos publicados. Para isso, foram analisadas postagens realizadas por Maria Eduarda Vieira no seu perfil no Instagram, @mariaeduardasv, com base nos conceitos de comunidade de marca estabelecidos por Muñiz e O’Guinn (2001). O estudo teve caráter qualitativo e proporcionou novas discussões no campo da comunicação sobre o tema.

description: A duality argument for the recently discovered chiral-nematic phase of the XY model in a triangular lattice is presented. We show that a new Ising variable naturally emerges in mapping the antiferromagnetic J1-J2 classical XY spin Hamiltonian onto an appropriate Villain model on a triangular lattice. The new variable is the chirality degree of freedom, which exists in addition to the usual vortex variables, in the dual picture. Elementary excitations and the associated phase transition of the Ising degrees of freedom are discussed in some detail.

description: The rich history of prime numbers includes great names such as Euclid, who first analytically studied the prime numbers and proved that there is an infinite number of them, Euler, who introduced the function $ζ(s)\equiv\sum_{n=1}^\infty n^{-s}=\prod_{p\,prime} \frac{1}{1- p^{-s}}$, Gauss, who estimated the rate at which prime numbers increase, and Riemann, who extended $ζ(s)$ to the complex plane $z$ and conjectured that all nontrivial zeros are in the $\mathbb{R}(z)=1/2$ axis. The nonadditive entropy $S_q=k\sum_ip_i\ln_q(1/p_i)\;(q\in\mathbb{R})$ involves the function $\ln_q z\equiv\frac{z^{1-q}-1}{1-q}\;(\ln_1 z=\ln z)$ that is interconnected to a $q$-generalized algebra, using $q$-numbers defined as $\langle x\rangle_q\equiv e^{\ln_q x}$ ($\langle x\rangle_1\equiv x$). The $q$-prime numbers are then defined as the $q$-natural numbers $\langle n\rangle_q\equiv e^{\ln_q n}\;(n=1,2,3,\dots)$, where $n$ is a prime number $p=2,3,5,7,\dots$ We show that, for any value of $q$, infinitely many $q$-prime numbers exist; for $q\le1$ they diverge for increasing prime number, whereas they converge for $q>1$; the standard prime numbers are recovered for $q=1$. For $q\le 1$, we generalize the $ζ(s)$ function as follows: $ζ_q(s)\equiv\langleζ(s)\rangle_q$ ($s\in\mathbb{R}$). We show that this function appears to diverge at $s=1+0$, $\forall q$. Also, we alternatively define, for $q\le 1$, $ζ_q^Σ(s)\equiv\sum_{n=1}^\infty\frac{1}{\langle n\rangle_q^s}=1+\frac{1}{\langle 2\rangle_q^s}+\dots $ and $ζ_q^Π(s)\equiv\prod_{p\,prime}\frac{1}{1-\langle p\rangle_q^{-s}}=\frac{1}{1-\langle 2\rangle_q^{-s}}\frac{1}{1-\langle 3\rangle_q^{-s}}\frac{1}{1-\langle 5\rangle_q^{-s}}\cdots$, which, for $q<1$, generically satisfy $ζ_q^Σ(s)

description: The presence of gender disparity in de jure rules across the world is relatively well-known. Many studies show that this disparity is detrimental to female labor participation. Our focus is different in that we examine whether firms with females amongst ownership experience elevated time costs and burdens associated with government regulations relative to their male-owned counterparts. In this sense, we are interested in both de facto and de jure differences in governmental regulation. Using firm-level data and two alternative matching methods, our results suggest that firms with at least one female owner report that senior management spends a larger percentage of their time dealing with regulations. We also find that construction permits take approximately 4–7 days longer to obtain for these same firms. Lastly, we find that female-owned firms perceive labor regulations to be a larger obstacle to business operations. In all cases, these effects tend to be largest in countries with the most disparity in de jure rules. However, the gap remains even in the most de jure equal countries.

description: Topological systems, such as fractional quantum Hall liquids, promise to successfully combat environmental decoherence while performing quantum computation. These highly correlated systems can support non-Abelian anyonic quasiparticles that can encode exotic entangled states. To reveal the non-local character of these encoded states we demonstrate the violation of suitable Bell inequalities. We provide an explicit recipe for the preparation, manipulation and measurement of the desired correlations for a large class of topological models. This proposal gives an operational measure of non-locality for anyonic states and it opens up the possibility to violate the Bell inequalities in quantum Hall liquids or spin lattices.

description: Aims: Zoonotic pathogens in bovine herds are major concerns for human and animal health, but their monitoring in animals can be challenging in the absence of clinical signs. Our objective was to determine the association between fecal excretion of Campylobacter jejuni, neonatal immunity, and personality traits of calves. Methods and results: Forty-eight dairy calves were reared in three indoor pens from birth to 4 weeks of life. Microbial analyses of the fecal samples collected weekly revealed that the proportion of calves naturally contaminated with C. jejuni in each pen reached 70% after 3 weeks of life. High (>16 g l−1) levels of IgG levels in the serum of neonatal calves were negatively (P = .04) associated with fecal detection of C. jejuni over the trial period. Calves that spent more time interacting with a novel object tended to be positive (P = .058) for C. jejuni. Conclusions: Overall, the findings indicate that the immunity of neonatal dairy animals and possibly the animal’s behavior may contribute to the fecal shedding of C. jejuni.
