description: We investigate the combinatorics of real double Hurwitz numbers with real positive branch points using the symmetric group. Our main focus is twofold. First, we prove correspondence theorems relating these numbers to counts of tropical real covers and study the structure of real double Hurwitz numbers with the help of the tropical count. Second, we express the numbers as counts of paths in a subgraph of the Cayley graph of the symmetric group. By restricting to real double Hurwitz numbers with real positive branch points, we obtain a concise translation of the counting problem in terms of tuples of elements of the symmetric group that enables us to uncover the beautiful combinatorics of these numbers both in tropical geometry and in the Cayley graph.

description: The intakes of air-breathing high-speed flying vehicles produce a large share of the thrust propulsion. Furthermore, the propulsion performance of these engines increases when the single-ramp intake is replaced with a multiple-ramps intake. Many scholars numerically and experimentally studied the high-speed engine performance over static single and multiple compression ramps. However, the transient behavior of the flow during the rotation of the double compression ramp from a single ramp is not fully investigated. The present paper aims to numerically investigate the transient shock reflection phenomenon over a rotating double wedge. The problem will start with a 3-Mach number inviscid flow over a single wedge. Then, a portion of the wedge will be rotated upstream at a quite low trailing Mach number to avoid the significant lag effect in the shock waves system. This idea could be applied in the supersonic intake or extensionally in the hypersonic intake of scramjets with a somehow complex mechanism. Further, the length of the rotating portion of the wedge will be changed three times to study its effect on the shock system. The results show a high gain in the pressure due to the rotation of the wedge. Moreover, the wave angles were larger at the low chord ratio value of $w_2/w_i= 0.25$ than at the high values of $w_2/w_i$ at the same second wedge rotating angle, $θ_2$, resulting in a higher pressure distribution.

merger

description: CLARIAH-DE brings together the data, tools and services of the two research infrastructure initiatives CLARIN-D and DARIAH-DE and the existing communities of users and providers of the infrastructures until 2021. CLARIN-D and DARIAH-DE can partly be seen as German equivalent of the European research infrastructure initiatives CLARIN and DARIAH. Potential users being aware of CLARIN and DARIAH, particularly users outside of the in-group, often wonder about the differences between both infrastructures and services. Most potential users want to access services and resources in the most convenient way, preferably with a single point of access, and want to use the services and resources they need, independent of their origin and also in combination. CLARIAH-DE also intends to open up resources for other communities and to extend its user base. After a year of collaborative work in CLARIAH-DE and also due to proceeding coordination efforts between CLARIN-D and DARIAH-DE, we have achieved first results: we were able to develop a common language and an understanding of the respective other infrastructure. The partners from different contexts have been successful in establishing a productive working groups. The integration of basic infrastructures is headed in the right direction. A first joint website is available and in the future becoming a single point of access to the data, tools, and services provided originally by the two infrastructures.

description: We use overlap fermions as valence quarks to calculate meson masses in a wide quark mass range on the $2+1$-flavor domain-wall fermion gauge configurations generated by the RBC and UKQCD Collaborations. The well-defined quark masses in the overlap fermion formalism and the clear valence quark mass dependence of meson masses observed from the calculation facilitate a direct derivation of physical current quark masses through a global fit to the lattice data, which incorporates $O(a^2)$ and $O(m_c^4a^4)$ corrections, chiral extrapolation, and quark mass interpolation. Using the physical masses of $D_s$, $D_s^*$ and $J/ψ$ as inputs, Sommer's scale parameter $r_0$ and the masses of charm quark and strange quark in the $\overline{\rm MS}$ scheme are determined to be $r_0=0.465(4)(9)$ fm, $m_c^{\overline{\rm MS}}(2\,{\rm GeV})=1.118(6)(24)$ GeV (or $m_c^{\overline{\rm MS}}(m_c)=1.304(5)(20)$ GeV), and $m_s^{\overline{\rm MS}}(2\,{\rm GeV})=0.101(3)(6)\,{\rm GeV}$, respectively. Furthermore, we observe that the mass difference of the vector meson and the pseudoscalar meson with the same valence quark content is proportional to the reciprocal of the square root of the valence quark masses. The hyperfine splitting of charmonium, $M_{J/ψ}-M_{η_c}$, is determined to be 119(2)(7) MeV, which is in good agreement with the experimental value. We also predict the decay constant of $D_s$ to be $f_{D_s}=254(2)(4)$ MeV. The masses of charmonium $P$-wave states $χ_{c0}, χ_{c1}$ and $h_c$ are also in good agreement with experiments.

description: Magnetic resonance imaging (MRI) provides patients with essential and detailed imaging examinations. However, metal objects may injure stakeholders in an environment with a strong magnetic field, especially when dealing with a crisis. Simulation-based education provides learners with an interactive, hands-on experience and enables them to apply what they have learned in a controlled and safe environment. This study explores gamification in simulation-based education for magnetic resonance imaging (MRI) safety, specifically in crisis resource management

 Method
 Twenty-one trainees participated in this curriculum, including emergency residents, intensive care unit nurses, and radiology interns. The teaching program included three sessions—first, time-bounded board games to estimate the core knowledge of MRI safety. Then, in the simulation center, trainees experienced an emergency event that happened in the MRI room. In the scenario, trainees also learned to use metal detectors to avoid mistakes. Next, the faculty facilitated debriefing after the simulation to deepen the impression and improve learning. In the end, trainees replay the board game to evaluate the changes. Then we used the paired t-test to analyze the
 difference between two times board game scores.

 Result
 At Kirkpatrick level 1, trainees rated 100% satisfaction with the curriculum. Furthermore, at Kirkpatrick level 2, the first-time board game score was 79.6, and the post-simulation score was 89.6. Paired t-test showed a significant statistical difference (P<0.001).

 Discussion
 Gamification, using game elements and design in non-game contexts, has been proposed to enhance engagement and motivation in educational contexts, including medical education. For example, in our study, a gamified MRI safety training program (board game and simulated scenarios) interested trainees and increased their core knowledge.

 Take home message
 Using gamification in simulation-based MRI safety education can help learners better understand and internalize the crucial principles of MRI safety

description: Abstract
This study presents the results of heavy metal concentrations in aquatic mosses collected from the Ave River Basin during two field surveys (campaigns II and III) and a comparison with data from a field survey carried out 15 years earlier (campaign I). The findings indicated high levels of chromium in the samples from the two previous campaigns, along with aggravated contamination of cadmium, lead, and zinc compared to campaign I. The order of metal accumulation in the moss samples, from highest to lowest, was Fe > Zn > Cu > Cr > Ni > Pb > Cd > Hg. The Metal Pollution Index (MPI) revealed changes in contamination levels between campaigns. Most stations experienced a decrease in classification due to increased water flow and reduced accumulation during Campaign II. The contamination patterns suggest the influence of industrial activities, particularly metal coating facilities. Overall, ongoing monitoring and mitigation efforts are necessary to address persistent heavy metal pollution in the Ave River Basin.

Our derivation does not depend on a particular implementation of the boundary conditions at the body surface and relies on general principles. We recover some well known expressions, in some cases with slight corrections, to treat the cases of static and moving bodies. We also present some numerical tests that support the correctness of the formulas derived.

description: We have conducted a line survey towards Orion KL using the Q-band receiver of Tianma 65 m radio telescope (TMRT), covering 34.8--50 GHz with a velocity resolution between 0.79 km s$^{-1}$ and 0.55 km s$^{-1}$ respectively. The observations reach a sensitivity on the level of 1-8 mK, proving that the TMRT is sensitive for conducting deep line surveys. In total, 597 Gaussian features are extracted. Among them, 177 radio recombination lines (RRLs) are identified, including 126, 40 and 11 RRLs of hydrogen, helium and carbon, with a maximum $Δn$ of 16, 7, and 3, respectively. The carbon RRLs are confirmed to originate from photodissociation regions with a $V_{\rm LSR}\sim$9 km s$^{-1}$. In addition, 371 molecular transitions of 53 molecular species are identified. Twenty-one molecular species of this survey were not firmly detected in the Q band by Rizzo et al. (2017), including species such as H$_2$CS, HCOOH, C$_2$H$_5$OH, H$_2^{13}$CO, H$_2$CCO, CH$_3$CHO, CH$_2$OCH$_2$, HCN $v_2=1$, and CH$_3$OCHO $v_t=1$. In particular, the vibrationally excited states of ethyl cyanide (C$_2$H$_5$CN $v$13/$v$21) are for the first time firmly detected in the Q band. NH$_3$ (15,15) and (16,16) are identified, and they are so far the highest transitions of the NH$_3$ inversion lines detected towards Orion KL. All the identified lines can be reproduced by a radiative transfer model.

description: In the pathwise stochastic calculus framework, the paper deals with the general study of equations driven by an additive Gaussian noise, with a drift function having an infinite limit at point zero. An ergodic theorem and the convergence of the implicit Euler scheme are proved. The Malliavin calculus is used to study the absolute continuity of the distribution of the solution. An estimation procedure of the parameters of the random component of the model is provided. The properties are transferred on a class of singular stochastic differential equations driven by a multiplicative noise. A fractional Heston model is introduced.

description: The transition between the Regular Reflection (RR) and Mach Reflection (MR) phenomenon impacts the design of the supersonic and hypersonic air-breathing vehicles. The aim of this paper is to numerically investigate the dynamic transition from RR to MR of unsteady supersonic flow over a two-dimensional wedge, whose trailing edge moves along the $x$-direction upstream with a velocity, $V(t)$ at a free-stream Mach number of $M_{\infty}=3$. The simulation is conducted using the unsteady compressible inviscid flow solver, which is implemented in OpenFOAM\textsuperscript{\textregistered}, the open-source CFD tool. Further, the wedge motion is applied by moving the mesh boundary, performing the Arbitrary Lagrangian-Eulerian (ALE) technique. In addition, the sonic and detachment criteria are used to define the dynamic transition from RR to MR during the increase of the wedge angle. Different reduced frequencies, $κ$, in the range of $[0.1-2]$ for the moving wedge are applied to study the lag in the dynamic transition from the steady-state condition. The results show that the critical value of $κ=0.4$ distinguishes between the rapid and gradual lag in the transition from RR to MR. In addition, the transition from RR to MR occurs above the Dual Solution Domain (DSD), since the shock is curved downstream during the rapid motion of the wedge.

description: Dipper stars are a classification of young stellar objects that exhibit dimming variability in their light curves, dropping in brightness by 10-50%, likely induced by occultations due to circumstellar disk material. This variability can be periodic, quasi-periodic, or aperiodic. Dipper stars have been discovered in young stellar associations via ground-based and space-based photometric surveys. We present the detection and characterization of the largest collection of dipper stars to date: 293 dipper stars, including 234 new dipper candidates. We have produced a catalog of these targets, which also includes young stellar variables that exhibit predominately bursting-like variability and symmetric variability (equal parts bursting and dipping). The total number of catalog sources is 414. These variable sources were found in a visual survey of TESS light curves, where dipping-like variability was observed. We found a typical age among our dipper sources of <5 Myr, with the age distribution peaking at ~2 Myr, and a tail of the distribution extending to ages older than 20 Myr. Regardless of the age, our dipper candidates tend to exhibit infrared excess, which is indicative of the presence of disks. TESS is now observing the ecliptic plane, which is rich in young stellar associations, so we anticipate many more discoveries in the TESS dataset. A larger sample of dipper stars would enhance the census statistics of light curve morphologies and dipper ages.

description: In vivo macromolecular crystallography (ivMX) has emerged as a prominent field, focusing on the study of protein crystals naturally occurring inside cells and organisms. It presents prospects for revolutionizing workflows by eliminating the need for sample purification and crystallization steps. Organisms perform these processes, streamlining protein preparation. Moreover, ivMX allows the investigation of proteins with post-translational modifications often overlooked in classical MX.
Global research efforts have shed light on the enigmatic events governing natural crystal growth. Integrating ivMX into Next-BINDS, Nagoya University fosters broad access and collaborative research.
This study unveils the latest advancements in the ivMX platform, which now is accepting project proposals. Our goals encompass enhancing automation at all steps of the ivMX pipeline. We also seek to synergize de novo protein design methods with ivMX, facilitating the exploration of unconventional protein structures, which prevales transformative insights into structure-function relationships.
The integration of the ivMX platform at Nagoya signifies an exhilarating phase in in vivo protein crystal research. We cordially invite researchers to leverage this platform for their inquiries. Through collaborative efforts, we are poised to unleash the full potential of ivMX, accelerating discoveries, and pioneering new avenues in structural biology and protein engineering.
Methods and Costs of Optimized Irrigation System Design Capacity Using Historical Evapotranspiration
Creators: name: Castillo, Claire Marie  Melad
Publisher: name: Washington State University
Year: 2024

description: Irrigation systems need adequate capacity to be able to replace the water used by the crop to avoid crop water stress, yet not so much that the irrigation system costs are excessive, and the irrigator must make constant on-off decisions to avoid over-watering. A method for calculating the irrigation system design capacity was developed that considers the daily and interannual evapotranspiration (ET) of a crop and its variability by using historical data and soil information. Also, cost estimates for excessive irrigation system capacity were estimated, and a simple irrigation guidance tool was developed. To demonstrate the process, historical evapotranspiration data were gathered from three climatically different locations in Washington State: near Prosser, Puyallup, and Omak to represent arid, humid, and mountain valley areas, respectively. The mean and standard deviation of the ET for each day of the year was used in the calculation of the minimum design capacity with a selectable probability of adequacy due to natural weather variability. Using the developed method, the net irrigation design capacity was adjusted to its minimum value such that during hot portions of the season the soil water could be depleted without resulting in water stress. Including the effects of the ET variability and a probability of adequacy increases the computed, required irrigation design capacity. This resulted in greater confidence in the chosen design capacities compared with the traditional methods of selecting design capacity, which simply uses the peak ET or maximum of the mean month ET. Calculating the irrigation design capacity without considering daily and interannual variability can result in more years of crop water stress due to inadequate system design. A cost vs design capacity curve was established for different irrigation systems. Increasing the design capacity also increases the costs of the system. Drip irrigation systems had the highest cost followed by center pivots, side roll, and then surface irrigation systems. Furthermore, to use the computed optimized design capacity, a simple irrigation scheduling guidance tool was developed to eliminate the struggle of farmers in making frequent decisions about when to turn on and off the irrigation system that will make sure the crop will not suffer stress since crop water timings are subject to the availability of labor. This tool creates an irrigation schedule for an average year that can be printed once and used forever as a general guide.
Genomic tools for comparative conservation genetics among three recently diverged stag beetles (Lucanus, Lucanidae)
Creators: name: Huang, Jen-Pan
Publisher: name: Zenodo
Year: 2023

description: We are witnessing a rapid decline in global biodiversity. International protocols and local conservation laws have been installed to counter such an unprecedented rate of decline. However, quantitatively evaluating how much biodiversity has been lost due to climatic and anthropogenic effects and how much biodiversity has been restored due to conservation efforts remain challenging. We applied a comparative conservation genomic approach to statistically and quantitatively address these questions using three geographical taxa from a stag beetle species complex. We found that the three sky-island taxa formed three independently evolving units without detectable post-divergence gene flow; furthermore, the three taxa, which have been divergent from each other since the mid-Pleistocene, have experienced episodes of demographic decline in the past. More importantly, even though idiosyncratic anthropogenic exploitations have been hypothesized to impact the recent demographic history (< 100 years) differently, we found a shared pattern of continuous decline in effective population size among the three geographical taxa. We argue that future empirical studies should include more taxa, in addition to the focal species, that may or may not be affected by the focal historical events to avoid making biased conservation plans.

description: We imaged the infrared dark clouds (IRDCs) G1.75-0.08 and G11.36+0.80 at 350 $μ$m and 450 $μ$m using the ArTéMiS bolometer. These data were used in conjunction with our previous 870 $μ$m observations with the Large APEX BOlometer CAmera (LABOCA). The clumps in G11.36+0.80 were also observed in the N$_2$H$^+(1-0)$ transition with the IRAM 30-metre telescope. G1.75-0.08 was found to be composed of two cold ($\sim14.5$ K), massive (several $\sim10^3$ M$_{\odot}$) clumps that are projectively separated by $\sim3.7$ pc. Both clumps are 70 $μ$m dark, but they do not appear to be bounded by self-gravity. The G1.75-0.08 filament was found to be subcritical by a factor of $\sim14$ with respect to its critical line mass. G11.36+0.80 was found to be moderately (by a factor of $\sim2$) supercritical and composed of four clumps. The dust temperatures of the clumps are $\sim13-15$ K, and their masses are in the range $\sim 232-633$ M$_{\odot}$. All the clumps are gravitationally bound. The projected, average separation of the clumps is $\sim1$ pc. A configuration that is observed in G1.75-0.08, namely two clumps at the ends of the filament, could be the result of gravitational focussing acting along the cloud. The two clumps fulfil the mass-radius threshold for high-mass star formation. Owing to the location of G1.75-0.08 near the Galactic centre ($\sim270$ pc), environmental effects such as a high level of turbulence, tidal forces, and shearing motions could affect the cloud dynamics. The observed clump separation in G11.36+0.80 can be understood in terms of a sausage instability. The G11.36+0.80 clumps do not lie above the mass-radius threshold for high-mass star formation. The substructure observed in one of the clumps in G11.36+0.80 suggests that the IRDC has fragmented in a hierarchical fashion. This conforms to the filamentary paradigm for Galactic star formation.

The design of a natural probabilistic layer on top of the model has been a long standing challenge. The difficulty comes from the presence of commuting pieces and from the absence of a global clock. In this paper, we introduce and study the class of Bernoulli probability measures that we claim to be the simplest adequate probability measures on infinite traces. For this, we strongly rely on the theory of trace combinatorics with the Möbius polynomial in the key role. These new measures provide a theoretical foundation for the probabilistic study of concurrent systems.

description: We show that the maximum entropy hypothesis can successfully explain the distribution of stresses on compact clusters of particles within disordered mechanically stable packings of soft, isotropically stressed, frictionless disks above the jamming transition. We show that, in our two dimensional case, it becomes necessary to consider not only the stress but also the Maxwell-Cremona force-tile area, as a constraining variable that determines the stress distribution. The importance of the force-tile area had been suggested by earlier computations on an idealized force-network ensemble.

description: We introduce transition operators that in a given basis of the single-site states of a many-body system have a single non-vanishing matrix element and introduce their correlation functions. We show that they fall into groups that decay with the same rate. The mutual information defined in terms of the von Neumann entropy between two sites is given in terms of these so-called generalized correlation functions. We confirm numerically that the long-distance decay of the mutual information follows the square of that of the most slowly decaying generalized correlation function. The main advantage of our procedure is that, in order to identify the most relevant physical processes, there is no need to know a priori the nature of the ordering in the system, i.e., no need to explicitly construct particular physical correlation functions. We explore the behavior of the mutual information and the generalized correlation functions for conformally invariant models and for the SU($n$) Hubbard model with $n=2,3,4$, and 5, which are, in general, not conformally invariant. In this latter case, we show that for filling $f=1/q$ and $q

description: After becoming ionized, low-density astrophysical plasmas will begin a process of slow recombination. Models for this still have significant uncertainties. The recombination cannot normally be observed in isolation, because the ionization follows the evolutionary time scale of the ionizing source. Laboratory experiments are unable to reach the appropriate conditions because of the required very long time scales. The extended nebula around the very late helium flash (VLTP) star V4334 Sgr provides a unique laboratory for this kind of study. The sudden loss of the ionizing UV radiation after the VLTP event has allowed the nebula to recombine free from other influences. More than 290 long slit spectra taken with FORS1/2 at the ESO VLT between 2007 and 2022 are used to follow the time evolution of lines of H, He, N, S, O, Ar. Hydrogen and helium lines, representing most of the ionized mass, do not show significant changes. A small increase is seen in [N II] (+2.8 %/yr; significance 2.7 sigma), while we see a decrease in [O III] (-1.96 %/yr; 2.0 sigma). The [S II] lines show a change of +3.0 %/yr; 1.6 sigma). The lines of [S III] and of Ar III] show no significant change. For [S III], the measurement differs from the predicted decrease by 4.5 sigma. A possible explanation is that the fraction of [S IV] and higher is larger than expected. Such an effect could provide a potential solution for the sulfur anomaly in planetary nebulae.

Theta divisors with curve summands and the Schottky problem

description: We prove the following converse of Riemann's Theorem: let (A,Θ) be an indecomposable principally polarized abelian variety whose theta divisor can be written as a sum of a curve and a codimension two subvariety Θ=C+Y. Then C is smooth, A is the Jacobian of C, and Y is a translate of W_{g-2}(C). As applications, we determine all theta divisors that are dominated by a product of curves and characterize Jacobians by the existence of a d-dimensional subvariety with curve summand whose twisted ideal sheaf is a generic vanishing sheaf.

Generalization of the Kuramoto model to the Winfree model by a symmetry breaking coupling

description: We construct a nontrivial generalization of the paradigmatic Kuramoto model by using an additional coupling term that explicitly breaks its rotational symmetry resulting in a variant of the Winfree Model. Consequently, we observe the characteristic features of the phase diagrams of both the Kuramoto model and the Winfree model depending on the degree of the symmetry breaking coupling strength for unimodal frequency distribution. The phase diagrams of both the Kuramoto and the Winfree models resemble each other for symmetric bimodal frequency distribution for a range of the symmetry breaking coupling strength except for region shift and difference in the degree of spread of the macroscopic dynamical states and bistable regions. The dynamical transitions in the bistable states are characterized by an abrupt (first-order) transition in both the forward and reverse traces. For asymmetric bimodal frequency distribution, the onset of bistable regions depends on the degree of the asymmetry. Large degree of the symmetry breaking coupling strength promotes the synchronized stationary state, while a large degree of heterogeneity, proportional to the separation between the two central frequencies, facilitates the spread of the incoherent and standing wave states in the phase diagram for a low strength of the symmetry breaking coupling. We deduce the low-dimensional equations of motion for the complex order parameters using the Ott-Antonsen ansatz for both unimodal and bimodal frequency distributions. We also deduce the Hopf, pitchfork, and saddle-node bifurcation curves from the evolution equations for the complex order parameters mediating the dynamical transitions. Simulation results of the original discrete set of equations of the generalized Kuramoto model agree well with the analytical bifurcation curves.
Self-gravitating disks around rapidly spinning, tilted black holes: General relativistic simulations

description: We perform general relativistic simulations of self-gravitating black hole-disks in which the spin of the black hole is significantly tilted ($45^\circ$ and $90^\circ$) with respect to the angular momentum of the disk and the disk-to-black hole mass ratio is $16\%-28\%$. The black holes are rapidly spinning with dimensionless spins up to $\sim 0.97$. These are the first self-consistent hydrodynamic simulations of such systems, which can be prime sources for multimessenger astronomy. In particular tilted black hole-disk systems lead to: i) black hole precession; ii) disk precession and warping around the black hole; iii) earlier saturation of the Papaloizou-Pringle instability compared to aligned/antialigned systems, although with a shorter mode growth timescale; iv) acquisition of a small black-hole kick velocity; v) significant gravitational wave emission via various modes beyond, but as strong as, the typical $(2,2)$ mode; and vi) the possibility of a broad alignment of the angular momentum of the disk with the black hole spin. This alignment is not related to the Bardeen-Petterson effect and resembles a solid body rotation. Our simulations suggest that any electromagnetic luminosity from our models may power relativistic jets, such as those characterizing short gamma-ray bursts. Depending on the black hole-disk system scale the gravitational waves may be detected by LIGO/Virgo, LISA and/or other laser interferometers.
Fermi-liquid theory for the single-impurity Anderson model

description: We generalize Nozières' Fermi-liquid theory for the low-energy behavior of the Kondo model to that of the single-impurity Anderson model. In addition to the electrons' phase shift at the Fermi energy, the low-energy Fermi-liquid theory is characterized by four Fermi-liquid parameters: the two given by Nozières that enter to first order in the excitation energy, and two additional ones that enter to second order and are needed away from particle-hole symmetry. We express all four parameters in terms of zero-temperature physical observables, namely the local charge and spin susceptibilities and their derivatives with respect to the local level position. We determine these in terms of the bare parameters of the Anderson model using Bethe Ansatz and Numerical Renormalization Group (NRG) calculations. Our low-energy Fermi-liquid theory applies throughout the crossover from the strong-coupling Kondo regime via the mixed-valence regime to the empty-orbital regime. From the Fermi-liquid theory, we determine the conductance through a quantum dot symmetrically coupled to two leads in the regime of small magnetic field, low temperature and small bias voltage, and compute the coefficients of the $\sim B^2$, $\sim T^2$, and $\sim V^2$ terms \textit{exactly} in terms of the Fermi-liquid parameters. The coefficients of $T^2$, $V^2$ and $B^2$ are found to change sign during the Kondo to empty-orbital crossover. The crossover becomes universal in the limit that the local interaction is much larger than the level width. For completeness, we also compute the shot noise and discuss the resulting Fano factor.

description: With the aim of finding microlensing binaries containing brown-dwarf (BD) companions, we investigate the microlensing survey data collected during the 2016--2018 seasons. For this purpose, we first conducted modeling of lensing events with light curves exhibiting anomaly features that are likely to be produced by binary lenses. We then sorted out BD-companion binary-lens events by applying the criterion that the companion-to-primary mass ratio is $q \lesssim 0.1$. From this procedure, we identify 6 binaries with candidate BD companions, including OGLE-2016-BLG-0890L, MOA-2017-BLG-477L, OGLE-2017-BLG-0614L, KMT-2018-BLG-0357L, OGLE-2018-BLG-1489L, and OGLE-2018-BLG-0360L. We estimate the masses of the binary companions by conducting Bayesian analyses using the observables of the individual lensing events. According to the Bayesian estimation of the lens masses, the probabilities for the lens companions of the events OGLE-2016-BLG-0890, OGLE-2017-BLG-0614, OGLE-2018-BLG-1489, and OGLE-2018-BLG-0360 to be in the BD mass regime are very high with $P_{\rm BD}> 80\%$. For MOA-2017-BLG-477 and KMT-2018-BLG-0357, the probabilities are relatively low with $P_{\rm BD}=61\%$ and 69\%, respectively.
