description: Since the Industrial Revolution at the end of the 18th century, anthropogenic changes in the environment have shifted from the local to the global scale. Even remote environments such as the high Arctic are vulnerable to the effects of climate change. Similarly, anthropogenic mercury (Hg) has had a global reach because of atmospheric transport and deposition far from emission point sources. Whereas some effects of climate change are visible through melting permafrost, or toxic effects of Hg at higher trophic levels, the often-invisible changes in microbial community structures and functions have received much less attention. With recent and drastic warming-related changes in Arctic watersheds, previously uncharacterized phylogenetic and functional diversity in the sediment communities might be lost forever. The main objectives of my thesis were to uncover how microbial community structure, functional potential and the evolution of mercury specific functions in lake sediments in northern latitudes (>54ºN) are affected by increasing temperatures and Hg deposition. To address these questions, I examined environmental DNA from sediment core samples and high-throughput sequencing to reconstruct the community composition, functional potential, and evolutionary responses to historical Hg loading. In my thesis I show that the microbial community in Lake Hazen (NU, Canada) sediments is structured by redox gradients and pH. Furthermore, the microbes in this phylogenetically diverse community contain genomic features which might represent adaptations to the cold and oligotrophic conditions. Finally, historical Hg pollution from anthropogenic sources has likely affected the evolution of microbial Hg resistance and this deposition can be tracked using sediment DNA on the Northern Hemisphere. My thesis underscores the importance of using culture-independent methods to reconstruct the structure, functional potential and evolution of environmental microbial communities.

description: We review the application of Statistical Mechanics methods to the study of online learning of a drifting concept in the limit of large systems. The model where a feed-forward network learns from examples generated by a time dependent teacher of the same architecture is analyzed. The best possible generalization ability is determined exactly, through the use of a variational method. The constructive variational method also suggests a learning algorithm. It depends, however, on some unavailable quantities, such as the present performance of the student. The construction of estimators for these quantities permits the implementation of a very effective, highly adaptive algorithm. Several other algorithms are also studied for comparison with the optimal bound and the adaptive algorithm, for different types of time evolution of the rule.

description: The semiclassical Einstein-Langevin equations which describe the dynamics of stochastic perturbations of the metric induced by quantum stress-energy fluctuations of matter fields in a given state are considered on the background of the ground state of semiclassical gravity, namely, Minkowski spacetime and a scalar field in its vacuum state. The relevant equations are explicitly derived for massless and massive fields arbitrarily coupled to the curvature. In doing so, some semiclassical results, such as the expectation value of the stress-energy tensor to linear order in the metric perturbations and particle creation effects, are obtained. We then solve the equations and compute the two-point correlation functions for the linearized Einstein tensor and for the metric perturbations. In the conformal field case, explicit results are obtained. These results hint that gravitational fluctuations in stochastic semiclassical gravity have a ``non-perturbative'' behavior in some characteristic correlation lengths.

(2020). Managing Risk Heterogeneity in Risk-Sharing Groups: A Multi-Method Study on Risk Aversion and Solidarity. Working Paper.' The data of the Broodfonds survey is not included in this data package, because it is only available upon request.

Abstract paper:
A recent revival of organizations that provide insurance in risk-sharing groups (e.g., Broodfonds in the Netherlands, Friendsurance in Germany) brings us back to the age-old question of how risk-sharing groups can survive despite their risk heterogeneity. Data tells us that members within these groups vary substantially in their risk of needing support, essentially meaning that low-risk members pay more to support others than they receive support in return. How can heterogeneous risk-sharing groups realize stable participation rates? In a multi-method study, we examine the potential of risk aversion and solidarity as compensators for heterogeneity by comparing the results of a survey conducted among 5192 members of 230 Broodfonds groups to an online experiment with 430 British subjects of the Prolific platform. While we find that risk heterogeneity has a negative effect on participation in Broodfonds groups, our experimental manipulation of heterogeneity has no significant effect. Moreover, risk aversion does not predict participation in the field study nor in the initial decision to join in the experiment. In the first, it only predicts participation for low-risk members and in the latter, it only explains continued participation. Solidarity motives, finally, are a strong predictor in both settings. These results have important implications for theories on sharing risk (in which traditionally risk aversion is a crucial factor) and for understanding what may make risk-sharing groups successful in practice.

description: Quantum spin Hall (QSH) effect is an intriguing phenomenon arising from the helical edge states in two-dimensional topological insulators. We use molecular beam epitaxy (MBE) to prepare FeSe films with atomically sharp nematic domain boundaries, where tensile strains, nematicity suppression and topological band inversion are simultaneously achieved. Using scanning tunneling microscopy (STM), we observe edge states at the Fermi level that spatially distribute as two distinct strips in the vicinity of the domain boundaries. At the endpoint of the boundaries, a bound state at the Fermi level is further observed. The topological origin of the edge states is supported by density functional theory calculations. Our findings not only demonstrate a candidate for QSH states, but also provide a new pathway to realize topological superconductivity in a single-component film.

description: Space asteroseismology reveals that stellar structure and evolution models of intermediate- and high-mass stars are in need of improvement in terms of angular momentum and chemical element transport. We aim to probe the interior structure of a hot massive star in the core-hydrogen burning phase of its evolution. We analyse CoRoT space photometry, Gaia DR2 space astrometry, and high-resolution high signal-to-noise HERMES and HARPS time-series spectroscopy of the slowly rotating B2V star HD 170580. From the time-series spectroscopy we derive $vsini=4\pm 2\,$km\,s$^{-1}$, where the uncertainty results from the complex pulsational line-profile variability. We detect 42 frequencies with amplitude above 5$σ$. Among these we identify 5 rotationally split triplets and 1 quintuplet. Asteroseismic modelling based on CoRoT, Gaia DR2 and spectroscopic data leads to a star of 8M$_\odot$ near core-hydrogen exhaustion and an extended overshoot zone. The detected low-order pressure-mode frequencies cannot be fit within the uncertainties of the CoRoT data by models without atomic diffusion. Irrespective of this limitation, the low-order gravity modes reveal HD 170580 to be a slow rotator with an average rotation period between 73 and 98 d and a hint of small differential rotation. Future Gaia DR3 data taking into account the multiplicity of the star, along with long-term TESS photometry would allow to put better observational constraints on the asteroseismic models of this blue evolved massive star. Improved modelling with atomic diffusion, including radiative levitation, is needed to achieve compliance with the low helium surface abundance of the star. This poses immense computational challenges but is required to derive the interior rotation and mixing profiles of this star.

Late-time decay of gravitational and electromagnetic perturbations along the event horizon

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We study analytically, via the Newman-Penrose formalism, the late-time decay of linear electromagnetic and gravitational perturbations along the event horizon (EH) of black holes. We first analyze in detail the case of a Schwarzschild black hole. Using a straightforward local analysis near the EH, we show that, generically, the ``ingoing'' ($s>0$) component of the perturbing field dies off along the EH more rapidly than its ``outgoing'' ($s<0$) counterpart. Thus, while along $r=const>2M$ lines both components of the perturbation admit the well-known $t^{-2l-3}$ decay rate, one finds that along the EH the $s<0$ component dies off in advanced-time $v$ as $v^{-2l-3}$, whereas the $s>0$ component dies off as $v^{-2l-4}$. We then describe the extension of this analysis to a Kerr black hole. We conclude that for axially symmetric modes the situation is analogous to the Schwarzschild case. However, for non-axially symmetric modes both $s>0$ and $s<0$ fields decay at the same rate (unlike in the Schwarzschild case).

description: It is generally accepted that vortex core is charged, what illustrates that even in stationary superconductors electric field may be present. Vortex structure and other properties of superconductors are usually calculated in the framework of the Ginzburg-Landau theory, which does not cover electric field. We show that the generalization of the GL theory due to Bardeen allows one to derive a third GL equation for the electrostatic potential. Since the Bardeen theory applies to all temperatures, the presented theory enables one to calculate charge profiles of the vortex under quite general conditions. The theory is consistent with the BCS-Gorkov results.

description: We present planet occurrence rate density models fit to Kepler data as a function of semi-major axis, planetary radius, and stellar effective temperature. We find that occurrence rates for M type stars with lower effective temperature do not follow the same trend as F, G, and K type stars when including a polynomial function of effective temperature in an occurrence rate density model and a better model fit includes a break in effective temperature. Our model fit for M type stars consists of power laws on semi-major axis and planetary radius. Our model fit for F, G, and K type stars consists of power laws on semi-major axis and planetary radius broken at 2.771$ R_\oplus $ and a quadratic function of stellar effective temperature. Our models show agreement with published occurrence rate studies and are the first to explicitly include stellar effective temperature as a variable. By introducing stellar effective temperature into our occurrence rate density models, we enable more accurate occurrence rate predictions for individual stars in mission simulation and science yield calculations for future and proposed exoplanet finding missions.

description: We developed a novel design of a Micro Pixel Chamber ($μ$-PIC) with resistive electrodes for a charged-particle-tracking detector in high-rate applications. Diamond-Like Carbon (DLC) thin film is used for the cathodes. The resistivity can be controlled flexibly ($\mathrm{10^{5-7}kΩ/sq.}$) at high uniformity. The fabrication-process was greatly improved and the resistive $μ$-PIC could be operated at 10$\times$10 $\mathrm{cm^2}$. Resistors for the HV bias and capacitors for the AC coupling were completely removed by applying PCB and carbon-sputtering techniques, and the resistive $μ$-PIC became a very compact detector. The performances of our new resistive $μ$-PIC were measured in various ways. Consequently, it was possible to attain high gas gains ($\mathrm{> 10^{4}}$), high detection efficiency, and position resolution exceeding 100 $μ$m. The spark current was suppressed, and the new resistive $μ$-PIC was operated stably under fast-neutrons irradiation. These features offer solutions for a charged-particle-tracking detector in future high-rate applications.

description: The broodfonds data was collected with a survey distributed among all 10230 members of the 230 broodfonds groups that were established before 1 Feb 2017. The data collection period ran from May 8, 2017 until June 14, 2017. Within this period, 5192 respondents (59.7%) filled in the questionnaire. This questionnaire contained questions about motivation for membership, personal characteristics, health and sickness, and social relations. All chairpersons of the 230 broodfonds group were invited to fill in a second questionnaire, which contained questions about the rules of their broodfonds group, the social relations within their group, the attendence at meetings, and sickness history of members of their broodfonds. This survey was completed for 196 of 230 groups (85.2%). The resulting dataset is a multilevel dataset with group-level and member-level properties.
The survey design and data collection has been executed in collaboration with the BroodfondsMakers. Given the sensitivity of some questions (e.g., on sickness history), data access is restricted.
Between Poisson and GUE statistics: Role of the Breit-Wigner width

description: We consider the spectral statistics of the superposition of a random diagonal matrix and a GUE matrix. By means of two alternative superanalytic approaches, the coset method and the graded eigenvalue method, we derive the two-level correlation function $X_2(r)$ and the number variance $Σ^2(r)$. The graded eigenvalue approach leads to an expression for $X_2(r)$ which is valid for all values of the parameter $λ$ governing the strength of the GUE admixture on the unfolded scale. A new twofold integration representation is found which can be easily evaluated numerically. For $λ\gg 1$ the Breit-Wigner width $Γ_1$ measured in units of the mean level spacing $D$ is much larger than unity. In this limit, closed analytical expression for $X_2(r)$ and $Σ^2(r)$ can be derived by (i) evaluating the double integral perturbatively or (ii) an ab initio perturbative calculation employing the coset method. The instructive comparison between both approaches reveals that random fluctuations of $Γ_1$ manifest themselves in modifications of the spectral statistics. The energy scale which determines the deviation of the statistical properties from GUE behavior is given by $\sqrt{Γ_1}$. This is rigorously shown and discussed in great detail. The Breit-Wigner $Γ_1$ width itself governs the approach to the Poisson limit for $r\to\infty$. Our analytical findings are confirmed by numerical simulations of an ensemble of $500\times 500$ matrices, which demonstrate the universal validity of our results after proper unfolding.

description: In this paper, we consider the boundary integral equation (BIE) method for solving the exterior Neumann boundary value problems of elastic and thermoelastic waves in three dimensions based on the Fredholm integral equations of the first kind. The innovative contribution of this work lies in the proposal of the new regularized formulations for the hyper-singular boundary integral operators (BIO) associated with the time-harmonic elastic and thermoelastic wave equations. With the help of the new regularized formulations, we only need to compute the integrals with weak singularities at most in the corresponding variational forms of the boundary integral equations. The accuracy of the regularized formulations is demonstrated through numerical examples using the Galerkin boundary element method (BEM).

description: It is shown that the event horizon of 4D black hole or $ds^2 = 0$ surfaces of multidimensional wormhole-like solutions reduce the amount of information necessary for determining the whole spacetime and hence satisfy the Holography principle. This leads to the fact that by matching two metrics on a $ds^2 = 0$ surface (an event horizon for 4D black holes) we can match only the metric components but not their derivatives. For example, this allows us to obtain a composite wormhole inserting a 5D wormhole-like flux tube between two Reissner-Nordström black holes and matching them on the event horizon. Using the Holography principle, the entropy of a black hole from the algorithm theory is obtained.

description: We use supersymmetric (SUSY) methods to study the delocalization transition at zero energy in a one-dimensional tight-binding model of spinless fermions with particle-hole symmetric disorder. Like the McCoy-Wu random transverse-field Ising model to which it is related, the fermionic problem displays two different correlation lengths for typical and mean correlations. Using the SUSY technique, mean correlators are obtained as quantum mechanical expectation values for an U(2|1,1) ``superspin''. In the scaling limit, this quantum mechanics is closely related to a 0+1-dimensional Liouville theory, allowing an interpretation of the results in terms of simple properties of the zero-energy wavefunctions. Our primary results are the exact two-parameter scaling functions for the mean single-particle Green's functions. We also show how the Liouville quantum mechanics approach can be extended to obtain the full set of multifractal scaling exponents τ(q), y(q) at criticality. A thorough understanding of the unusual features of the present theory may be useful in applying SUSY to other delocalization transitions.

description: The energy conditions of general relativity permit one to deduce very powerful and general theorems about the behaviour of strong gravitational fields and cosmological geometries. However, the energy conditions these theorems are based on are beginning to look a lot less secure than they once seemed: (1) there are subtle quantum effects that violate all of the energy conditions, and more tellingly (2), there are also relatively benign looking classical systems that violate all the energy conditions. This opens up a Pandora's box of rather disquieting possibilities --- everything from negative asymptotic mass, to traversable wormholes, to warp drives, up to and including time machines.

description: $^{59}$Co and $^{31}$P nuclear magnetic resonance (NMR) measurements in external magnetic and zero magnetic fields have been performed to investigate the magnetic properties of the A-type antiferromagnetic (AFM) CaCo$_2$P$_2$. NMR data, especially, the nuclear spin lattice relaxation rates 1/$T_1$ exhibiting a clear peak, provide clear evidence for the AFM transition at a Néel temperature of $T_{\rm N}\sim$110~K. The magnetic fluctuations in the paramagnetic state were found to be three-dimensional ferromagnetic, suggesting ferromagnetic interaction between Co spins in the ${\it ab}$ plane characterize the spin correlations in the paramagnetic state. In the AFM state below $T_{\rm N}$, we have observed $^{59}$Co and $^{31}$P NMR signals under zero magnetic field. From $^{59}$Co NMR data, the ordered magnetic moments of Co are found to be in $ab$ plane and are estimated to be 0.35 $μ_{\rm B}$ at 4.2 K. Furthermore, the external field dependence of $^{59}$Co NMR spectrum in the AFM state suggests a very weak magnetic anisotropy of the Co ions and also provides microscopic evidence of canting the Co ordered moments along the external magnetic field directions. The magnetic state of the Co ions in CaCo$_2$P$_2$ is well explained by the local moment picture in the AFM state, although the system is metallic as seen by $1/T_1T$ = constant behavior.

description: We study the hydrodynamical stability of the laminar flows associated with warped astrophysical discs using numerical simulations of warped shearing boxes. We recover linear growth rates reported previously due to a parametric resonance of inertial waves, and show that the nonlinear saturated state can significantly reduce the laminar flows, meaning that the warp would evolve on much longer time scales than would be concluded from the internal torques due to these laminar flows. Towards larger warp amplitudes, we find first of all a reversal of angular momentum flux, indicating that the mass distribution would evolve in an anti-diffusive manner, and second that the linear growth rates disappear, possibly because of the very strong shear in the laminar flows in this regime. For discs with small enough viscosity, a nonlinear state can still be found when linear growth rates are absent by introducing a large enough perturbation, either by starting from a nonlinear state obtained at smaller warp amplitude, or by starting from a state with no laminar flows.

description: This folder contains the oTree code and final dataset of the Risk-Sharing experiment. The risk-sharing experiment was programmed in oTree and conducted with Uk-based participants recruited from the Prolific platform between June 5 and June 11. In total, 525 people showed up for these sessions (68% of those who signed up), of which 430 could be assigned to a risk-sharing group. 424 subjects completed the entire experiment. The experiment consisted of four parts. First, the subjects had to independently answer five questions of the staircase method (Falk et al. 2016) to measure risk-preferences. Secondly, they were paired to another subject and had to answer 15 questions of the Social Value Orientation Slider Measure. The third part was the main part of the experiment: the heterogeneous risk-sharing game. In this game, groups of 10 subjects had to decide for 20 rounds whether or not they wanted to share the risk of getting sick and not generating an income with each other. If they shared risk, they would pay a contribution that would be used to pay sick members each round. If they didn't, they would earn their full income or nothing at all (in case they were sick). One round was randomly drawn for payout in order to incentivize participants to share risk (and thus smooth their income). The subjects in the experiment had different risks, but in one condition this varied between 0.15 and 0.25, whereas in the other it varied between 0.07 and 0.33. The aim of the experiment was to study when people were willing to share risk despite heterogeneity in risk preferences (which drives up the costs for low-risk participants). The last part consisted of a survey that asked about motivations to join the risk-sharing group and basic socio-demographics.

This folder contains the apps created for the oTree experiment, information about the experiment, and the final dataset.

description: We study the dynamic structure factor $S(\vec{q},ω)$ of superfluid 4He at zero temperature in the roton momentum region and beyond using field-theoretical Green's function techniques. We start from the Gavoret-Nozières two-particle propagator and introduce the concept of quasiparticles. We treat the residual (weak) interaction between quasiparticles as being local in coordinate space and weakly energy dependent. Our quasiparticle model explicitly incorporates the Bose-Einstein condensate. A complete formula for the dynamic susceptibility, which is related to $S (\vec{q},ω)$, is derived. The structure factor is numerically calculated in a self-consistent way in the special case of a momentum independent interaction between quasiparticles. Results are compared with experiment and other theoretical approaches.

description: This folder contains all files used for the Risk-Sharing experiment. The risk-sharing experiment was programmed in oTree and conducted with Uk-based participants recruited from the Prolific platform between June 5 and June 11. In total, 525 people showed up for these sessions (68% of those who signed up), of which 430 could be assigned to a risk-sharing group. 424 subjects completed the entire experiment. The experiment consisted of four parts. First, the subjects had to independently answer five questions of the staircase method (Falk et al. 2016) to measure risk-preferences. Secondly, they were paired to another subject and had to answer 15 questions of the Social Value Orientation Slider Measure. The third part was the main part of the experiment: the heterogeneous risk-sharing game. In this game, groups of 10 subjects had to decide for 20 rounds whether or not they wanted to share the risk of getting sick and not generating an income with each other. If they shared risk, they would pay a contribution that would be used to pay sick members each round. If they didn't, they would earn their full income or nothing at all (in case they were sick). One round was randomly drawn for payout in order to incentivize participants to share risk (and thus smooth their income). The subjects in the experiment had different risks, but in one condition this varied between 0.15 and 0.25, whereas in the other it varied between 0.07 and 0.33. The aim of the experiment was to study when people were willing to share risk despite heterogeneity in risk preferences (which drives up the costs for low-risk participants). The last part consisted of a survey that asked about motivations to join the risk-sharing group and basic socio-demographics.

This folder contains the apps created for the oTree experiment, all administrative data about the subjects that signed up and participated for the experiment, all raw datasets, a script to merge and clean these datasets and the final datafile. The access to this folder is closed, because it contains information about all subject IDs from the Prolific participants. The final dataset is publicly available.

description: Modern optical flow methods are often composed of a cascade of many independent steps or formulated as a black box neural network that is hard to interpret and analyze. In this work we seek for a plain, interpretable, but learnable solution. We propose a novel inpainting based algorithm that approaches the problem in three steps: feature selection and matching, selection of supporting points and energy based inpainting. To facilitate the inference we propose an optimization layer that allows to backpropagate through 10K iterations of a first-order method without any numerical or memory problems. Compared to recent state-of-the-art networks, our modular CNN is very lightweight and competitive with other, more involved, inpainting based methods.

Phase separation in the 2D Hubbard model: a fixed-node quantum Monte Carlo study

description: Fixed-node Green's function Monte Carlo calculations have been performed for very large 16x6 2D Hubbard lattices, large interaction strengths U=10,20, and 40, and many (15-20) densities between empty and half filling. The nodes were fixed by a simple Slater-Gutzwiller trial wavefunction. For each value of U we obtained a sequence of ground-state energies which is consistent with the possibility of a phase separation close to half-filling, with a hole density in the hole-rich phase which is a decreasing function of U. The energies suffer, however, from a fixed-node bias: more accurate nodes are needed to confirm this picture. Our extensive numerical results and their test against size, shell, shape and boundary condition effects also suggest that phase separation is quite a delicate issue, on which simulations based on smaller lattices than considered here are unlikely to give reliable predictions.

Testosterone, Social Environment and Trust

subject: trust
subject: Trust Game
subject: testosterone administration
subject: social environment
subject: one-shot games
subject: repeated games

description: In this experiment we systematically vary the characteristics of the social environment and show that, depending on prenatal sex hormone priming, testosterone administration in women moderates the effect of the social environment on trust. We use the economic trust game and compare one-shot games modelling trust problems in relations between strangers with repeated games modelling trust problems in ongoing relations between partners. The trust game not only models important features of social and economic interactions, manipulating features of the game also allows to systematically vary the relative demands on cognitive empathy.

Our experiment was a double-blind, placebo-controlled study, employing a between subjects design with a total of 82 young, healthy female subjects (mean age (± s.d.) 22.4 ±  2.2 yr). All subjects provided written informed consent to the protocol of the study that was approved by the medical ethics committee of the University Medical Centre Utrecht. The protocol followed established procedures for experiments on testosterone effects and trust games. Testosterone and placebo were administered sublingually. Since the parameters (quantity and time course) for inducing neurophysiological effects after a sublingual testosterone administration are known in women but not in men, we exclusively recruited women. Subjects received a single dose of testosterone or placebo four hours before performing the main game tasks. Administration followed the established Tuiten method. Drug samples consisted of 0.5 mg of testosterone, 5 mg of cyclodextrin (carrier), 5 mg of ethanol, and 5 mL of water. Testosterone was omitted from the placebo samples.
Since effects of testosterone administration on cognitive empathy seem to depend on priming through prenatal testosterone, we included effects of 2D:4D ratio in the analyses. 2D:4D ratio has been established as an individual marker for differences in prenatal testosterone-to-estradiol ratio. 2D:4D ratio was measured from a scan of the right hand of the subjects, a valid method to measure finger lengths.
Each subject played six one-shot trust games with six different partners and a repeated game of six rounds with one and the same partner. Subjects were informed about behaviour of their partner after each game in both series of games. Half of the subjects started with the one-shot games, the other half with the repeated game. Each subject played in the same role throughout all games.  As a result, we had twelve observations per subject, six in the one-shot games and six in the repeated game, with a total of 480 observations from 40 investors and 492 observations from 41 trustees.

description: We show that the standard Hamiltonian of isotropic loop quantum cosmology is selected by physical criteria plus one choice: that it have a `minimal' number of terms. We also show the freedom, and boundedness of energy density, even when this choice is relaxed. A criterion used is covariance under dilations, the continuous diffeomorphisms remaining in this context, which are not canonical but conformally canonical transformations. We propose how to implement conformally canonical transformations in quantum theory. Removal of the infrared regulator yields independence of ordering ambiguities.

description: Dynamical jets are generally found on Light bridges (LBs), which are key to studying sunspots decays. So far, their formation mechanism is not fully understood. In this paper, we used state-of-the-art observations from the Goode Solar Telescope, the Interface Region Imaging Spectrograph, the Spectro-Polarimeter on board Hinode and the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory to analyze the fan shape jets on LBs in detail. Continuous upward motion of the jets in ascending phase is found from the H$α$ velocity, which lasts for 12 minutes and is associated with the H$α$ line wing enhancements. Two mini jets appear upon the bright fronts of the fan shape jets visible in the AIA 171 Å and 193 Å channels, with a time interval as short as 1 minute. Two kinds of small scale convective motions are identified in the photospheric images, along with the H$α$ line wing enhancements. One seems to be associated with the formation of a new convection cell and the other manifests as the motion of a dark lane passing through the convection cell. The finding of three lobes Stokes V profiles and their inversion with NICOLE code indicates that there is magnetic field lines with opposite polarities in LBs. From the H$α$ -0.8 Å images, we found ribbon like brightenings propagating along the LBs, possibly indicating slipping reconnection. Our observation supports that the fan shape jets under study are caused by the magnetic reconnection and photospheric convective motions play an important role in triggering the magnetic reconnection.
