description: Longslit spectra of the Seyfert galaxy NGC 4151 from the UV to near infrared have been obtained with STIS to study the kinematics and physical conditions in the NLR. The kinematics show evidence for three components, a low velocity system in normal disk rotation, a high velocity system in radial outflow at a few hundred km/s relative to the systemic velocity and an additional high velocity system also in outflow with velocities up to 1400 km/s, in agreement with results from STIS slitless spectroscopy (Hutchings et al., 1998, Kaiser et al., 1999, Hutchings et al., 1999) We have explored two simple kinematic models and suggest that radial outflow in the form of a wind is the most likely explanation. We also present evidence indicating that the wind may be decelerating with distance from the nucleus. We find that the emission line ratios along our slits are all entirely consistent with photoionization from the nuclear continuum source. A decrease in the [OIII]5007/H-beta and [OIII]5007/[OII]3727 ratios suggests that the density decreases with distance from the nucleus. This trend is borne out by the [SII] ratios as well. We find no strong evidence for interaction between the radio jet and the NLR gas in either the kinematics or the emission line ratios in agreement with the results of Kaiser et al. (1999) who find no spatial coincidence of NLR clouds and knots in the radio jet. These results are in contrast to other recent studies of nearby AGN which find evidence for significant interaction between the radio source and the NLR gas.

description: We discuss radiative backreaction for global strings described by the Kalb-Ramond action with an analogous derivation to that for the point electron in classical electrodynamics. We show how local corrections to the equations of motion allow one to separate the self-field of the string from that of the radiation-field. Modifications to this 'local backreaction approximation' circumvent the runaway solutions familiar from electrodynamics, allowing these corrections to be used to evolve string trajectories numerically. Comparisons are made with analytic and numerical radiation calculations from previous work and the merits and limitations of this approach are discussed. Finally, we comment on the relevance of this work to simulations of a cosmological network of global or axion strings. These methods can also be applied to describe graviational, electromagnetic and other forms of string radiative backreaction.

description: Detailed male meiosis has been made in two species of genus Withania collected from desert regions of Rajasthan, India. The study revealed 2n=48 for both the species. The meiotic analysis of W. somnifera is reported to be normal whereas, W. coagulans showed abnormal meiosis with the presence of abnormalities like spindle irregularities, chromatin transfer, laggards and irregular microsporogensis with the presence of monads, dyads, triads, polyads and tetrads with micronuclei which further lowered the pollen fertility and giving rise to varying size pollen grains. Both the species are widely used for various medicinal purposes by local/tribal people of the state.

description: In this work, we present a calculation of the triton $β$-decay lifetime using Nuclear Lattice Effective Field Theory (NLEFT) at next-to-next-to-next-to-leading order in the chiral expansion. By incorporating a non-perturbative treatment of the higher-order corrections, we achieve consistent predictions for the Fermi and Gamow-Teller matrix elements, which are crucial for determining the triton lifetime. Our results are consistent with earlier theoretical calculations, confirming the robustness of our approach. This study marks a significant advancement in the systematic application of NLEFT to nuclear $β$-decay processes, paving the way for future high-precision calculations in more complex nuclear systems. Additionally, we discuss potential improvements to our approach, including the explicit inclusion of two-pion exchange mechanisms and the refinement of three-nucleon forces. These developments are essential for extending the applicability of NLEFT to a broader range of nuclear phenomena, including neutrinoless double-$β$ decay.

description: This study analysed the karyotype of Cyrtodactylus kunyai and C. interdigitalis from Loei Province in Northeastern Thailand. The metaphase and meiotic chromosome preparations were obtained by squash technique from bone marrow and testes, respectively. The chromosomes were stained by Giemsa staining and Ag-NOR-banding techniques. The results showed diploid chromosome number (2n) of 40 for C. kunyai and 42 for C. interdigitalis. The chromosome types of metacentric, submetacentric, acrocentric and telocentric chromosomes were 8-4-0-28 and 4-2-4-32, respectively. The Ag-NORs banding technique provides the pair of nucleolar organizer regions (NORs) of both two species at telomeric region of the long arm of the pair 12, metacentric type in C. kunyai and telocentric type in C. interdigitalis. There are no sex differences in karyotypes between males and females of both two species. We found that during metaphase I on meiosis of C. kunyai and C. interdigitalis, the homologous chromosomes showed synapsis of 20 and 21 bivalents, respectively. Moreover, the meiotic phase on prophase II exhibited 20 and 21 haploid chromosome number (n) as respective diploid species. Their karyotype formulas is as follows: C. kunyai (2n = 40): Lm2 + Lsm4 + Lt4 + Mt6 + Sm6 + St18, and C. interdigitalis (2n = 42): La4 + Lt14 + Mt2 + Sm4 + Ssm2 + St16.

description: Observations of gravitational waves from neutron star mergers open up novel directions for exploring fundamental physics: they offer the first access to the structure of objects with a non-negligible contribution from vacuum energy to their total mass. The presence of such vacuum energy in the inner cores of neutron stars occurs in new QCD phases at large densities, with the vacuum energy appearing in the equation of state for a new phase. This in turn leads to a change in the internal structure of neutron stars and influences their tidal deformabilities which are measurable in the chirp signals of merging neutron stars. By considering three commonly used neutron star models we show that for large chirp masses the effect of vacuum energy on the tidal deformabilities can be sizable. Measurements of this sort have the potential to provide a first test of the gravitational properties of vacuum energy independent from the acceleration of the Universe, and to determine the size of QCD contributions to the vacuum energy.

description: We present first results of a comprehensive survey of deep long-slit spectra along the minor axis of bulges of edge-on spiral galaxies. Our results indicate that stellar populations in bulges are fairly old and encompass a range of metallicities. The luminosity-weighted ages of bulges range from those found for cluster ellipticals to slightly ``younger'' (by up to only a few Gyr, however). Their $α$/Fe element ratio is typically supersolar, consistent with those found in giant ellipticals. The radial line-strength gradients in bulges correlate with bulge luminosity. Generally, these findings are more compatible with predictions of the ``dissipative collapse'' model than with those of the ``secular evolution'' model.

description: The Weak Equivalence Principle states that the geodesics of a test particle in a gravitational field are independent of the particle's constitution. To constrain violations of the Weak Equivalence Principle, we use the one-meter telescope at Table Mountain Observatory near Los Angeles to monitor the relative arrival times of pulses from the Crab Pulsar in the optical ($λ\approx 585$ nm) and near-infrared ($λ\approx 814$ nm) using an instrument which detects single photons with nanosecond-timing resolution in those two bands. The infrared pulse arrives slightly before the visible pulse. Our three analysis methods give delays with statistical errors of $Δt_{obs} = 7.41 \pm 0.58$, $0.4 \pm 3.6$, and $7.35 \pm 4.48$ microseconds (at most 1/4000 of the pulsar period). We attribute this discrepancy to systematic error from the fact that the visible and infrared pulses have slightly different shapes. Whether this delay emerges from the pulsar, is caused by passing through wavelength-dependent media, or is caused by a violation of the equivalence principle, unless there is a fine-tuned cancellation among these, we set the first upper limit on the differential post-Newtonian parameter at these wavelengths of $Δγ< 1.07 \times 10^{-10}~(3σ)$. This result falls in an unexplored region of parameter space and complements existing limits on equivalence-principle violation from fast radio bursts, gamma ray bursts, as well as previous limits from the Crab.

Intracellular and extracellular green synthesis of silver nanoparticles using Desmodesmus sp.: their Antibacterial and antifungal effects
Creators: name: Öztürk, Betül Yilmaz

description: In this study aim was to perform green synthesis of synthesis silver nanoparticles (LAC-AgNPs, RAE-AgNPs and BAE-AgNPs) by using Desmodesmus sp., intracellular and extracellular synthesis methods and to compare the obtained products with physicochemical characterization techniques. The structural, morphological and optical properties of the synthesized nanoparticles were characterized using UV-Vis spectroscopy, TEM, SEM-EDS, FTIR, DLS and zeta potential. These results clearly show that silver nanoparticles (AgNPs) could be synthesized in different sizes and stabilities with various biological materials obtained from Desmodesmus sp. LAC-AgNPs had size of 10-30 nm, RAE-AgNPs had size of 4-8 nm and BAE-AgNPs had size of 3-6 nm. Also, the antibacterial activity of silver nanoparticles synthesized as intracellular and extracellular showed a strong antibacterial effect against pathogens such as Salmonella sp. and Listeria monocytogenes. Additionally, they have effective antifungal activity against Candida parapsilosis. The broth microdilution method was used for examining antibacterial antifungal effect of synthesis AgNPs. The minimum inhibitory concentration against Salmonella sp., Listeria monocytogenesis and Candida parapsilosis were recorded as 3,125 μl, 1,5625 µl and 0,78125 µl synthesis AgNPs, respectively. As a result, it has thought that different sizes of synthesis AgNPs may have a great potential for biomedical applications.

description: Karyotypes in 12 taxa of Gundelia are compared, based on Feulgen-stained somatic metaphase chromosomes. The karyotypes of G. anatolica, G. asperrima, G. cilicica, G. colemerikensis, G. dersim, G. glabra, G. komagenensis, G. mesopotamica, G. munzuriensis and G. vitekii are described for the first time. Karyological analyses indicate relationships among the species with respect to their asymmetry indices. All Gundelia species studied were diploid with 2n = 2x = 18 chromosomes. All karyotypes are symmetrical, consisting of metacentric and submetacentric chromosomes. The submetacentric chromosomes of all the investigated specimens contain a secondary constriction. Three chromosome types were identified according to the position of the secondary constrictions. The chromosomes ranged in size from 2.00 µm to 7.02 µm. The total haploid chromosome length (THL) varied from 24.97 μm (G. asperrima) to 42.56 μm (G. rosea). To determine the karyological relationships among taxa, PCoA (Principal Coordinate Analysis) with six uncorrelated parameters was performed.

Gas Dynamics in the LINER Galaxy NGC 5005: Episodic Fueling of a Nuclear Disk

description: We report high-resolution CO(1-0) observations in the central 6 kpc of the LINER galaxy NGC 5005 with the Owens Valley Radio Observatory millimeter array. Molecular gas is distributed in three components - a ring at a radius of about 3 kpc, a strong central condensation, and a stream to the northwest of the nucleus but inside the 3 kpc ring. The central condensation is a disk of about 1 kpc radius with a molecular gas mass of 2 x 10^9 M_sun. The stream between the 3 kpc ring and the nuclear disk lies on a straight dust lane seen in the optical. If this material moves in the plane of the galaxy, it has a velocity offset by up to ~ 150 km/s from galactic rotation. We suggest that an optically inconspicuous stellar bar lying within the 3 kpc ring can explain the observed gas dynamics. This bar is expected to connect the nuclear disk and the ring along the position angle of the northwest stream. A position-velocity cut in this direction reveals features which match the characteristic motions of gas in a barred potential. Our model indicates that gas in the northwest stream is on an x_1 orbit at the bar's leading edge; it is falling into the nucleus with a large noncircular velocity, and will eventually contribute about 2 x 10^8 M_sun to the nuclear disk. If most of this material merges with the disk on its first passage of pericenter, the gas accretion rate during the collision will be 50 M_sun/yr. We associate the nuclear disk with an inner 2:1 Lindblad resonance, and the 3 kpc ring with an inner 4:1 Lindblad resonance. The high rate of bar-driven inflow and the irregular appearance of the northwest stream suggest that a major fueling event is in progress in NGC 5005. Such episodic (rather than continuous) gas supply can regulate the triggering of starburst and accretion activity in galactic nuclei. (abridged)

description: To date, most molecular phylogenetic studies of Apocynaceae have been based on plastid DNA regions or nuclear ribosomal DNA. In this study, we used part of the PHYA (phytochrome A) exon, a low-copy nuclear gene, and combined it with the trnL-F region (intron and spacer) to investigate placement of Periplocoideae, intergeneric relationships of Asclepiadoideae and relationships within Rauvolfioideae. We included 112 taxa representing most major clades of Apocynaceae. The study confirms that both subfamilies Apocynoideae and Rauvolfioideae are paraphyletic and that Periplocoideae are nested within Apocynoideae. The APSA clade (Apocynoideae, Periplocoideae, Secamonoideae and Asclepiadoideae) is strongly supported here, but the crown clade of Apocynaceae (comprised of subfamilies Asclepiadoideae, Secamonoideae, Periplocoideae and Echiteae, Mesechiteae, Odontadenieae and Apocyneae of Apocynoideae) has only moderate support. The present study places Periplocoideae as part of the sister group to the rest of the crown clade. This contrasts with results from the previous only PHYA and plastid marker–based studies in which periplocoids appeared as sister to a clade comprising Baisseeae (Apocynoideae) plus Secamonoideae and Asclepiadoideae. Old World Cynanchinae form a well-supported clade with the New World MOG (Metastelmatinae, Oxypetalinae and Gonolobinae) tribes rather than with the largely Old World. Asclepiadinae and Tylophorinae, as suggested by earlier studies. In our combined analyses, resolution among most groups is improved as compared to previous plastid-only analyses.

description: Parametrizing energy functions for ionic systems can be challenging. Here, the total energy function for an eutectic system consisting of water, SCN$^-$, K$^+$ and acetamide is improved vis-a-vis experimentally measured properties. Given the importance of electrostatic interactions, two different types of models are considered: the first (model M0) uses atom-centered multipole whereas the other two (models M1 and M2) are based on fluctuating minimal distributed charges (fMDCM) that respond to geometrical changes of SCN$^-$. The Lennard-Jones parameters of the anion are adjusted to best reproduce experimentally known hydration free energies and densities which are matched to within a few percent for the final models irrespective of the electrostatic model. Molecular dynamics simulations of the eutectic mixtures with varying water content (between 0% and 100%) yield radial distribution functions and frequency correlation functions for the CN-stretch vibration. Comparison with experiments indicate that models based on fMDCM are considerably more consistent that those using multipoles. Computed viscosities from models M1 and M2 are within 30% of measured values and their change with increasing water content is consistent with experiments. This is not the case for model M0.

description: We propose that the noncentrosymmetric LiGaGe-type hexagonal $ABC$ crystal SrHgPb realizes a new type of topological semimetal that hosts both Dirac and Weyl points in momentum space. The symmetry-protected Dirac points arise due to a band inversion and are located on the sixfold rotation $z$-axis, whereas the six pairs of Weyl points related by sixfold symmetry are located on the perpendicular $k_z=0$ plane. By studying the electronic structure as a function of the buckling of the HgPb layer, which is the origin of inversion symmetry breaking, we establish that the coexistence of Dirac and Weyl fermions defines a phase separating two topologically distinct Dirac semimetals. These two Dirac semimetals are distinguished by the $\mathbb{Z}_2$ index of the $k_z=0$ plane and the corresponding presence or absence of 2D Dirac fermions on side surfaces. We formalize our first-principles calculations by deriving and studying a low-energy model Hamiltonian describing the Dirac-Weyl semimetal phase. We conclude by proposing several other materials in the non-centrosymmetric $ABC $ material class, in particular SrHgSn and CaHgSn, as candidates for realizing the Dirac-Weyl semimetal.

description: We report on the determination of $|V_{cb}|$ from the comparison of the semileptonic inclusive decay rates of B-- and D--mesons using the heavy quark symmetry of QCD. While the renormalization scale ambiguity does not allow for a reliable estimate of the quark masses, it almost cancels in the prediction for $|V_{cb}|$, which reads $|V_{cb}|(τ_B/1.49\,{\rm ps})^{1/2} = 0.036\pm 0.005$, where the error stems from the uncertainty in the kinetic energy of the heavy quark inside the meson, in the experimental branching ratios, in QCD input parameters, and from scale uncertainties. This talk is based on research work done in collaboration with Patricia Ball.

description: We discuss electronic properties and their evolution for the linear chain of $H_2$ molecules in the presence of a uniform external force $f$ acting along the chain. The system is described by an extended Hubbard model within a fully microscopic approach. Explicitly, the microscopic parameters describing the intra- and inter-site Coulomb interactions are determined together with the hopping integrals by optimizing the system ground state energy and the single-particle wave functions in the correlated state. The many-body wave function is taken in the Jastrow form and the Variational Monte-Carlo (VMC) method is used in combination with an ab initio approach to determine the energy. Both the effective Bohr radii of the renormalized single-particle wave functions and the many-body wave function parameters are determined for each $f$. Hence, the evolution of the system can be analyzed in detail as a function of the equilibrium intermolecular distance, which in turn is determined for each $f$ value. The transition to the atomic state, including the Peierls distortion stability, can thus be studied in a systematic manner, particularly near the threshold of the dissociation of the molecular into atomic chain. The computational reliability of VMC approach is also estimated.
A Possible 100-day X-ray-to-Optical Lag in the Variations of the Seyfert 1 Nucleus NGC 3516

description: We present optical broadband (B and R) observations of the Seyfert 1 nucleus NGC 3516, obtained at Wise Observatory from 1997 March to 1998 September, contemporaneously with the X-ray 2-10 keV measurements of RXTE. The cross correlation function shows a positive peak when the optical variations lead the X-rays by about 100 days. We show that the putative correlation signal at 100 days is entirely due to the slow ($\gtorder 30$ days) components of the light curves. During the first year or this monitoring, smoothed versions of the light curves are nearly identical copies of each other, but scaled in amplitude and shifted in time. However, for the next 200 days, the X-ray and optical variations are clearly different. During the whole period, the faster-changing components of the light curves are uncorrelated at any lag. The detection of this lag is tentative and the significance of the correlation uncertain. If the 100-day delay is real, however, one interpretation is that that the slowly-varying part of the X-ray emission is an echo of the optical emission, Compton scattered from a medium located about 50-100 lt days from the optical source. We point out that a possibly analogous phenomenon, of a lag between hard and soft X-rays for a given variability timescale, exists in Galactic stellar-mass accretors. Remarkably, in both cases the lag corresponds to a light travel distance of order $10^4$ gravitational radii. Alternatively, the lag may not represent a physical size, but for example, the timescale of an instability propagating inward in an accretion flow, appearing first in the optical and then in the X-rays. In any event, there is no strong correlation at zero, or small positive, lag, ruling out an energetically-significant X-ray reprocessed component in the optical emission.

description: The semicontinuity phenomenon of the ADM mass under pointed (i.e., local) convergence of asymptotically flat metrics is of interest because of its connections to nonnegative scalar curvature, the positive mass theorem, and Bartnik's mass-minimization problem in general relativity. In this paper, we extend a previously known semicontinuity result in dimension three for $C^2$ pointed convergence to higher dimensions, up through seven, using recent work of S. McCormick and P. Miao (which itself builds on the Riemannian Penrose inequality of H. Bray and D. Lee). For a technical reason, we restrict to the case in which the limit space is asymptotically Schwarzschild. In a separate result, we show that semicontinuity holds under weighted, rather than pointed, $C^2$ convergence, in all dimensions $n \geq 3$, with a simpler proof independent of the positive mass theorem. Finally, we also address the two-dimensional case for pointed convergence, in which the asymptotic cone angle assumes the role of the ADM mass.

description: In four dimensions, 't Hooft symbols offer a compact and powerful framework for describing the self-dual structures fundamental to instanton physics. Extending this to six dimensions, the six-dimensional 't Hooft symbols can be constructed using the isomorphism between the Lorentz group $Spin(6)$ and the unitary group $SU(4)$. We demonstrate that the six-dimensional self-dual structures governed by the Hermitian Yang-Mills equations can be elegantly organized using these generalized 't Hooft symbols. We also present a systematic method for constructing Hermitian Yang-Mills instantons from spin connections on six-dimensional manifolds using the generalized 't Hooft symbols. We provide a thorough analysis of the topological invariants such as instanton and Euler numbers.

Cosmic Curvature Tested Directly from Observations

description: Cosmic spatial curvature is a fundamental geometric quantity of the Universe. We investigate a model independent, geometric approach to measure spatial curvature directly from observations, without any derivatives of data. This employs strong lensing time delays and supernova distance measurements to measure the curvature itself, rather than just testing consistency with flatness. We define two curvature estimators, with differing error propagation characteristics, that can crosscheck each other, and also show how they can be used to map the curvature in redshift slices, to test constancy of curvature as required by the Robertson-Walker metric. Simulating realizations of redshift distributions and distance measurements of lenses and sources, we estimate uncertainties on the curvature enabled by next generation measurements. The results indicate that the model independent methods, using only geometry without assuming forms for the energy density constituents, can determine the curvature at the $\sim6\times10^{-3}$ level.

description: This work interprets the internal representations of deep neural networks trained for classification of diseased tissue in 2D mammograms. We propose an expert-in-the-loop interpretation method to label the behavior of internal units in convolutional neural networks (CNNs). Expert radiologists identify that the visual patterns detected by the units are correlated with meaningful medical phenomena such as mass tissue and calcificated vessels. We demonstrate that several trained CNN models are able to produce explanatory descriptions to support the final classification decisions. We view this as an important first step toward interpreting the internal representations of medical classification CNNs and explaining their predictions.
Cornwall-Jackiw-Tomboulis effective field theory to nonuniversal equation of state of an ultracold Bose gas

Year: 2024
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: The equation of state (EOS) serves as a cornerstone in elucidating the properties of quantum many-body systems. A recent highlight along this research line consists of the derivation of the nonuniversal Lee-Huang-Yang (LHY) EOS for an ultracold quantum bosonic gas with finite-range interatomic interactions using one-loop effective path-integral field theory. The purpose of this work is to extend Salasnich's pioneering work to uncover beyond-LHY corrections to the EOS by employing the Cornwall-Jackiw-Tomboulis (CJT) effective field theory, leveraging its two-loop approximation. In this end, we expand Salasnich's remarkable findings of EOS to the next leading order characterized by $\left(ρa_{\text{s}}^{3}\right)^{2}$, with $ρ$ and $a_{\text{s}}$ being the density and the $s$-wave scattering length. Notably, we derive analytical expressions for quantum depletion and chemical potential, representing the next-to-LHY corrections to nonuniversal EOS induced by finite-range effects. Moreover, we propose an experimental protocol of observing the nonuniversal next-to-LHY corrections to the EOS by calculating fractional frequency shifts in the breathing modes. The nonuniversal beyond-LHY EOS in this work paves the way of using LHY effects in quantum simulation experiments and for investigations beyond the LHY regime.

description: We consider a geometrically motivated Skyrme model based on a general covariant kinetic term proposed originally by Born and Infeld. We introduce this new term by generalizing the Born-Infeld action to a non-abelian $SU(2)$ gauge theory and by using the hidden gauge symmetry formalism. The static properties of the Skyrmion are then analyzed and compared with other Skyrme-like models.

Structure, dynamics and evolution of disk galaxies in a hierarchical formation scenario

description: Using galaxy evolutionary models in a hierarchical formation scenario, we predict the structure, dynamics and evolution of disk galaxies in a LCDM universe. Our models include star formation and hydrodynamics of the ISM. We find that the Tully-Fisher relation (TFR) in the I and H bands is an imprint of the mass-velocity relation of the cosmological dark halos. The scatter of the TFR originates mainly from the scatter in the dark halo structure and, to a minor extension, from the dispersion of the primordial spin parameter lambda. Our models allow us to explain why low and high surface brightness galaxies have the same TFR. The disk gas fractions predicted agree with the observations. The disks formed within the growing halos have nearly exponential surface brightness and flat rotation curves. Towards high redshifts, the zero-point of the TFR in the H band increases while in the B-band it slightly decreases.

Isospin Structure of Penguins And Their Consequences in $B$ Physics

description: Isospin structure of gluon mediated or strong penguin is significantly altered when the full electroweak corrections are included. This has the consequence that some previous analyses which relied on a simple isospin structure in charmless $B$ decays become inapplicable. We present the general Hamiltonian in next-to-leading order QCD, and illustrate our conclusion quantitatively for $B\rightarrow ππ$ and $B\rightarrow Kπ$ decays in the factorization approximation. Some remarks on CP asymmetries in $B$ decays are also made.

Compression stiffening in biological tissues: on the possibility of classic elasticity origins

description: Compression stiffening, or an increase in shear modulus with increasing compressive strain, has been observed in recent rheometry experiments on brain, liver, and fat tissues. Here, we extend the known types of biomaterials exhibiting this phenomenon to include agarose gel and fruit flesh. Further, we show that two different results from classic elasticity theory can account for the phenomenon of linear compression stiffening. One result is due to Barron and Klein, extended here to the relevant geometry and pre-stresses; the other is due to Birch. For incompressible materials, there are no adjustable parameters in either theory. Which one applies to a given situation is a matter of reference state, suggesting that the reference state is determined by the tendency of the material to develop, or not develop, axial stress (in excess of the applied pre-stress) when subjected to torsion at constant axial strain. Our experiments and analysis also strengthen the notion that seemingly distinct animal and plant tissues can have mechanically similar behavior under certain conditions.

description: In this paper, we explore the interactions between light axion-like particles (ALPs) and top quarks, gluons, and W-bosons. Utilizing high-energy probes at the LHC, we probe these couplings in the context of single top quark production associated with a W-boson and an ALP. We analyze the latest LHC Run II data on $t\bar{t}$ spin correlation measurements to establish constraints on these couplings. Additionally, we compare these constraints with those derived from loop-induced couplings and indirect searches involving B-meson decays. Furthermore, we derive two-dimensional limits on the ALP couplings with top quarks and gluons.
