description: Phase field models are promising to tackle various fracture problems where a diffusive crack is introduced and modelled using the phase variable. Owing to the non-convexity of the energy functional, the derived partial differential equations are usually solved in a staggered manner. However, this method suffers from a low convergence rate, and a large number of staggered iterations are needed, especially at the fracture nucleation and propagation. In this study, we propose novel staggered schemes, which are inspired by the fixed-stress split scheme in poromechanics. By fixing the stress when solving the damage evolution, the displacement increment is expressed in terms of the increment of the phase variable. The relation between these two increments enables a prediction of the displacement and the active energy based on the increment of the phase variable. Thus, the maximum number of staggered iterations is reduced, and the computational efficiency is improved. We present three staggered schemes by fixing the first invariant, second invariant, or both invariants of the stress, denoted by S1, S2, and S3 schemes. The performance of the schemes is then verified by comparing with the standard staggered scheme through three benchmark examples, i.e., tensile, shear, and L-shape panel tests. The results exhibit that the force-displacement relations and the crack patterns computed using the fast schemes are consistent with the ones based on the standard staggered scheme. Moreover, the proposed S1 and S2 schemes can largely reduce the maximum number of staggered iterations and total CPU time in all benchmark tests. The S2 scheme performs comparably except in the shear test, where the underlying assumption is violated in the region close to the crack.

description: We report 1,656 new star clusters found in the Galactic disk (|b|<20 degrees) beyond 1.2 kpc, using Gaia EDR3 data. Based on an unsupervised machine learning algorithm, DBSCAN, and followed our previous studies, we utilized a unique method to do the data preparation and obtained the clustering coefficients, which proved to be an effective way to search blindly for star clusters. We tabulated the physical parameters and member stars of the new clusters, and presented some interesting examples, including a globular cluster candidate. The cluster parameters and member stars are available at CDS via anonymous ftp to https://cdsarc.cds.unistra.fr/ftp/vizier.submit//he22c. We examined the new discoveries and discussed their statistical properties. The proper motion dispersions and radii of the new clusters were the same as the previously reported ones. The new star clusters beyond 1.2 kpc were older than those in the solar neighborhood, and the new objects found in the third Galactic quadrant presented the lowest line-of-sight extinctions. Combined with our previous results, the total population of new clusters detected through our method was 2,541, corresponding to 55% of all newly published clusters in the Gaia era. The number of cataloged Gaia star clusters was also increased to nearly six thousand. In the near future, it is necessary to make a unified confirmation and member star determination for all reported clusters.

description: Polygamous marriage is widely practiced in our country. About 14% of currently married women are in polygamous union with marked regional variations. Although polygamy is widely practiced, there are very few studies on its health or economic consequences. A total of 692 currently married women (226 in polygamous and 466 in monogamous union) aged 15-49 were selected in the Meskan and Mareko District southern Ethiopia using multistage systematic random sampling. Qualitative and quantitative methods were used to collect data. The study aimed at examining the effect of polygamous marriage on the nutritional status and reproductive health women. In addition the study tried to compare the two groups of women in terms of their socio-demographic & economic characteristics, decision making power, occurrence of diseases and health seeking behavior, nutritional status and selected elements of reproductive health. Result showed that women in polygamous union were more affected by chronic energy deficiency (CED) compared to those in monogamous union. [AOR (95% CI) : 1.55 (1.08,2.22). However attendance of ANC and use of family planning were not found to be significantly different between the two marriage forms (polygamous and monogamous). Urbanization and literacy of both women and husbands were the factors identified to be affecting both the nutritional status and reproductive health of women. More women in polygamous union were older in age, Moslem, illiterate and had previous marriages compared to those in monogamous union. Polygamous husbands were illiterate, farmers and had more number of children compared to monogamous husbands, which was significant. Although women in polygamous union possessed farmland they were at risk of having farm product insufficiency. On the average women in polygamous union vii compared to those in monogamous union got married earlier (mean age at first marriage 15.8 Vs 16.3), had larger number of pregnancies (5.61 Vs 4.8) and deliveries (5.3 Vs 4.7) where the observed differences were significant. The decision making power were at largely under the husbands'. Women in polygamous union seemed to exercise more decisions making compared to women in monogamous union except for major decisions where the difference became negligible. In conclusion women in polygamous union were at socio-demographic, socioeconomic, nutritional and reproductive health disadvantages. Hence there is a need to discourage polygamy through religious leaders, community participation and involvement of other related sectors. Urban residence and enhancing the educational level of both men and women are the key factors in improving both the nutritional and reproductive health states of women.

description: Unconventional Weyl point with nonlinear dispersion features higher topological charge $|{\cal{C}}|>1$ and multiple topologically protected Fermi arc states at its boundary. As a novel topological state, it has been attracting widespread attention. However, the unconventional Weyl point with $|{\cal{C}}|=3$ has not yet been reported in realistic materials, even though it has been theoretically proposed for more than a decade. In this work, based on first-principles calculations and theoretical analysis, we predict the existing material, $\rmα$-LiIO$_3$ as the first realistic example with this unconventional Weyl point. Particularly, in the phonon spectra of $\rmα$-LiIO$_3$, two Weyl points with ${\cal{C}}=-3$, connected by time-reversal symmetry, appear at the neck crossing-point of a hourglass-type band, leading to two hourglass charge-3 Weyl phonons. The symmetry protection and the associated novel triple- and sextuple-helicoid surface arc states of the hourglass charge-3 Weyl phonons are revealed. Our results uncover a hidden topological character of $\rmα$-LiIO$_3$ and also show that the phonon spectra is a great platform for exploring unconventional topological states.

description: Within the framework of local analytic sector subtraction, we present the subtraction of next-to-leading-order QCD singularities for processes featuring massless coloured particles in the initial as well as in the final state. The features of the method are explained in detail, including the introduction of an optimisation procedure aiming at improving numerical stability at the cost of no extra analytic complexity. A numerical validation is provided for a variety of processes relevant to lepton as well as hadron colliders. This work constitutes a relevant step in view of the application of our subtraction method to processes involving initial-state radiation at next-to-next-to-leading order in QCD.

description: One of the major science goals of the Square Kilometre Array (SKA) is to understand the role played by atomic hydrogen (HI) gas in the evolution of galaxies throughout cosmic time. The hyperfine transition line of the hydrogen atom at 21-cm is one of the best tools to detect and study the properties of HI gas associated with galaxies. In this article, we review our current understanding of HI gas and its relationship with galaxies through observations of the 21-cm line both in emission and absorption. In addition, we provide an overview of the HI science that will be possible with SKA and its pre-cursors and pathfinders, i.e. HI 21-cm emission and absorption studies of galaxies from nearby to high redshifts that will trace various processes governing galaxy evolution.

description: A new, frequency modulation mechanism for zonal flow pattern formation is presented. The model predicts the probability distribution function of the flow strength as well as the evolution of the characteristic spatial scale. Magnetic toroidicity-induced global phase dynamics is shown to determine the spatial structure of the flow. A key result is the observation that global phase patterning can lead to zonal flow formation in the absence of turbulence inhomogeneity.

title: Dental health and dental care utilization among childbearing age Asian women immigrants in Canada
Creators: name: Li, Qianqian
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: This study examines the dentistry care utilization, self-reported dental health status, and oral health issues of Asian immigrants and Asian women immigrants of childbearing age, using the combined Canadian Community Health Survey from 2012-2014 and 2011-2014 data. Reports show that amongst Asian immigrants and Asian women immigrants of childbearing age, there are significantly lower frequency of dental care utilization compared to non-immigrant counterparts. Furthermore, the difference in dentist visiting behavior between native-born Canadians and Asian immigrants mitigated with increase in length of residence in Canada. Socioeconomic status, lifestyle factors, dental health and dental insurance coverage cannot fully explain the behavioral differences in visiting the dentist between Asian immigrants and Asian women immigrants of childbearing age compared to the native-born citizens. For both Asian immigrants and Asian women immigrants of childbearing age, the primary reason for not visiting the dentist in the last three years is that the “Respondent did not think necessary.” This response is much different than reasons for not visiting the dentist provided by other groups which such as the “cost” and “haven’t gotten around to it.” Asian immigrants, as well as Asian women of childbearing age, had a significantly greater risk of tooth extracted due to tooth decay than other ethnicities. Asian immigrants also had a higher prevalence of having fair or poor selfreported dental health than Canadian born residences. Surprisingly, the prevalence of dental health problems for Asian immigrants is like that of a native-born Canadians, with Asian women immigrants of childbearing age showing the least prevalence of dental symptoms among the three population groups. Our results suggest that oral health beliefs in the lack of necessity in dental services exist among recent Asian immigrants and Asian women immigrants of childbearing age, with their oral health gradually changing over time throughout their stay in Canada. Early symptoms of dental problems that lead to decay may most likely result from the lack of visits to the dentist in Asian immigrants. Finally, the study findings do not appear to support the ‘Healthy Immigrant Effect’ for dental health and teeth issues.

description: A key issue in the development of high-performance semiconductor devices is the ability to properly measure active dopants at the nanometer scale. 4D scanning transmission electron microscopy and off-axis electron holography have opened up the possibility of studying the electrostatic properties of a p-n junction with nm-scale spatial resolution. The complete description of a p-n junction must take into account the precise evolution of the concentration of dopants around the junction, since the sharpness of the dopant transition directly influences the built-in potential and the maximum electric field. Here, a contacted silicon p-n junction is studied through in-situ biased 4D-STEM. Measurements of electric field, built-in voltage, depletion region width and charge density in the space charge region are combined with analytical equations as well as finite-element simulations in order to evaluate the quality of the junction interface. The nominally-symmetric, highly doped ($N_A = N_D = 9\space x \space10^{18} cm^{-3}$) junction presents an electric field and built-in voltage much lower than expected for an abrupt junction. These experimental results are consistent with electron holography data. All measured junction parameters are compatible with the presence of an intermediate region with a graded profile of the dopants at the p-n interface. This hypothesis is also consistent with the evolution of the electric field with bias. These results demonstrate that in-situ biased 4D-STEM enables a better understanding of the electrical properties of semiconductor p-n junctions with nm-scale resolution.

description: We investigate the optical properties of silicon-vacancy (SiV) and germanium-vacancy (GeV) color centers in nanodiamonds under hydrostatic pressure up to 180 GPa. The nanodiamonds were synthetized by Si or Ge-doped plasma assisted chemical vapor deposition and, for our experiment, pressurized in a diamond anvil cell. Under hydrostatic pressure we observe blue-shifts of the SiV and GeV zero-phonon lines by 17 THz (70 meV) and 78 THz (320 meV), respectively. These measured pressure induced shifts are in good agreement with ab initio calculations that take into account the lattice compression based on the equation of state of diamond and that are extended to the case of the tin-vacancy (SnV) center. This work provides guidance on the use of group-IV-vacancy centers as quantum sensors under extreme pressures that will exploit their specific optical and spin properties induced by their intrinsic inversion-symmetric structure.

Competition between shock and turbulent heating in coronal loop system

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: 2.5-dimensional magnetohydrodynamic (MHD) simulations are performed with high spatial resolution in order to distinguish between competing models of the coronal heating problem. A single coronal loop powered by Alfvén waves excited in the photosphere is the target of the present study. The coronal structure is reproduced in our simulations as a natural consequence of the transportation and dissipation of Alfvén waves. Further, the coronal structure is maintained as the spatial resolution is changed from 25 to 3 km, although the temperature at the loop top increases with the spatial resolution. The heating mechanisms change gradually across the magnetic canopy at a height of 4 Mm. Below the magnetic canopy, both the shock and the MHD turbulence are dominant heating processes. Above the magnetic canopy, the shock heating rate reduces to less than 10 % of the total heating rate while the MHD turbulence provides significant energy to balance the radiative cooling and thermal conduction loss or gain. The importance of compressibility shown in the present study would significantly impact on the prospects of successful MHD turbulence theory in the solar chromosphere.

description: The first interstellar meteor larger than dust was detected by US government sensors in 2014, identified as an interstellar object candidate in 2019, and confirmed by the Department of Defense in 2022. Here, we describe an additional interstellar object candidate in the CNEOS fireball catalog, and compare the implied material strength of the two objects, referred to here as IM1 and IM2, respectively. IM1 and IM2 are ranked 1 and 3 in terms of material strength out of all 273 fireballs in the CNEOS catalog. Fitting a log-normal distribution to material strengths of objects in the CNEOS catalog, IM1 and IM2 are outliers at the levels of $3.5 σ$ and $2.6 σ$, respectively. The random sampling and Gaussian probabilities, respectively, of picking two objects with such high material strength from the CNEOS catalog, are $\sim 10^{-4}$ and $\sim 10^{-6}$. If IM2 is confirmed, this implies that interstellar meteors come from a population with material strength characteristically higher than meteors originating from within the solar system. Additionally, we find that if the two objects are representative of a background population on random trajectories, their combined detections imply that $\sim 40\%$ of all refractory elements are locked in meter-scale interstellar objects. Such a high abundance seemingly defies a planetary system origin.

description: In principle, the strong-interaction sector of the Standard Model is characterised by a unique renormalisation-group-invariant (RGI) running interaction and a unique form for the dressed--gluon-quark vertex, $Γ_μ$; but, whilst much has been learnt about the former, the latter is still obscure. In order to improve this situation, we use a RGI running-interaction that reconciles both top-down and bottom-up analyses of the gauge sector in quantum chromodynamics (QCD) to compute dressed-quark gap equation solutions with 1,660,000 distinct Ansaetze for $Γ_μ$. Each one of the solutions is then tested for compatibility with three physical criteria and, remarkably, we find that merely 0.55% of the solutions survive the test. Plainly, therefore, even a small selection of observables places extremely tight bounds on the domain of realistic vertex Ansaetze. This analysis and its results should prove useful in constraining insightful contemporary studies of QCD and hadronic phenomena.

description: The dynamical impact of Lyman-alpha (Lyα) radiation pressure on galaxy formation depends on the rate and duration of momentum transfer between Lyα photons and neutral hydrogen gas. Although photon trapping has the potential to multiply the effective force, ionizing radiation from stellar sources may relieve the Lyα pressure before appreciably affecting the kinematics of the host galaxy or efficiently coupling Lyα photons to the outflow. We present self-consistent Lyα radiation-hydrodynamics simulations of high-$z$ galaxy environments by coupling the Cosmic Lyα Transfer code (COLT) with spherically symmetric Lagrangian frame hydrodynamics. The accurate but computationally expensive Monte-Carlo radiative transfer calculations are feasible under the one-dimensional approximation. The initial starburst drives an expanding shell of gas from the centre and in certain cases Lyα feedback significantly enhances the shell velocity. Radiative feedback alone is capable of ejecting baryons into the intergalactic medium (IGM) for protogalaxies with a virial mass of $M_{\rm vir} \lesssim 10^8~{\rm M}_\odot$. We compare the Lyα signatures of Population III stars with $10^5$ K blackbody emission to that of direct collapse black holes with a nonthermal Compton-thick spectrum and find substantial differences if the Lyα spectra are shaped by gas pushed by Lyα radiation-driven winds. For both sources, the flux emerging from the galaxy is reprocessed by the IGM such that the observed Lyα luminosity is reduced significantly and the time-averaged velocity offset of the Lyα peak is shifted redward.

description: We study rigidly rotating and pulsating strings in the background of a 1+1 dimensional intersection of two orthogonal stacks of fivebranes in type IIB string theory by using the Neumann-Rosochatius (NR) model. Starting with the Polyakov action of the probe fundamental string we show that a generalised ansatz reduce the system into the one dimensional NR model in the presence of flux. The integrable construction of the model is exploited to analyze the rotating and oscillating string solution. We render the large $J$ BMN-type expansion for the energy of rotating string states while the same for the oscillating string has been derived in long string and small angular momenta limit.

description: Introduction: Despite the introduction and widespread use of Rhesus (Rh) D immunoglobulin for prevention of hemolytic disease of the fetus/newborn (HDFN), Rh alloimmunization remains a significant problem in perinatology. Care management with anti-D prophylaxis in patients presenting with severe alloimmunization is difficult to access in Sub-Saharan Africa. Objective: This study aims to determine the prevalence and assess the existing mechanism for management of Rh negative pregnant women in Gandhi Memorial hospital. Methods: A cross sectional study using quantitative and qualitative methods was used in the study. A total of 497 women case files were included in the study from September, 2012 to August, 2014 to determine the prevalence by using systematic random sampling. Then another 384 case files of Rh negative women was included by simple random sampling for assessment of the management of Rh negative pregnancy. SPSS was used for data entry and analysis .Tables were used to show the results, percents and frequencies to describe the variables. Univariate and Bivariate analysis using Chi square was conducted and p value was determined. In the qualitative method in-depth interview with 7 key informants by using purposive sampling, to assess the availability and affordability issues of medication was done. Data was analyzed as per the procedure i.e. recording, transcribing, translation and organizing and content analysis was conducted using open code software. Result The prevalence of Rh negative was 7.2% with 95%CI (6.9, 7.5). The utilization rate of Anti D was 14.3%. There was 4.7% offer of RAADP at 28 weeks. Regarding Anti D administration all socio demographic factors included in the study were not statistically significant with anti D administration. Qualitative data suggest that special consideration is necessary on this issue Conclusion and Recommendation The prevalence of Rh negative women is of a high magnitude keeping in view the prevalence rate of the other African countries estimate. There is lack of proper management of Rh negative pregnant women. Special attention should be given to Rh negative pregnancy to be included in maternal health programs by Ministry of health, donors and other collaborators.

description: Gibt es einen Kauf-Knopf im Gehirn des Konsumenten? Und wenn ja, wie betätigt man die-sen? Die Antwort aus der Hirnforschung lautet "Nein, einen solchen Knopf gibt es nicht". Zwar haben Neurowissenschaftler in den letzten Jahren wichtige Erkenntnisse über das menschliche Gehirn und dessen Funktionsweise gewonnen, doch eine Allround-Lösung zur Beeinflussung von Kaufentscheidungen konnte bisher noch nicht gefunden werden. Dennoch können die Ergebnisse, die durch neurowissenschaftlicher Methoden erzielt wurden, auch im Marketing angewandt werden. Durch den Blick ins Kundengehirn, können Händler diese ge-zielter ansprechen und sich so einen Vorteil gegenüber Konkurrenten verschaffen. Im Rahmen dieser Arbeit werden zunächst die wichtigsten Begriffe geklärt und anschließend ein Überblick über das menschliche Gehirn und die neurowissenschaftlichen Methoden zu dessen Erforschung vorgestellt. Anschließend werden die wichtigsten Einflüsse auf die Ent-scheidung von Konsumenten, Emotionen und das Unbewusste, sowie der Einsatz von Codes in der Werbung näher erläutert. Abschließend wird die Umsetzung neurowissenschaftlicher Erkenntnisse im Marketing anhand von fünf Best Practice Beispielen aus dem Handel ver-deutlicht.

description: We express the planar five- and six-gluon two-loop Yang-Mills amplitudes with all positive helicities in compact analytic form using D-dimensional local integrands that are free of spurious singularities. The integrand is fixed from on-shell tree amplitudes in six dimensions using D-dimensional generalised unitarity cuts. The resulting expressions are shown to have manifest infrared behaviour at the integrand level. We also find simple representations of the rational terms obtained after integration in 4-2epsilon dimensions.

Assessment of Noise induced hearing loss and Associated Factors among Workers in Akaki basic Metal Industry, Addis Ababa, Ethiopia
Creators: name: Hailu, Ashenafi
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background: - Excessive occupational exposure to noise results in a well-recognized occupational hearing loss and now is taken as a global problem. Worldwide, approximately 600 million workers are exposed and 16% of disabling hearing loss in adults is attributed to occupational noise. However, in developing countries including Ethiopia there is no systematized recording and reporting of noise induced health problems. Objectives: - To assess the magnitude and associated factors of noise induced hearing loss among Akaki basic metal Industry workers, between March and April, 2015. Methodology: - Institutional based cross-sectional study was conducted in Akaki Basic metal Industry. A total of 244 eligible workers were included in study by using simple random sampling from workers` attendance sheet of respective sections. A pre-tested interviewing questionnaire, Environment noise survey, audiometric test were conducted. Epi-Info version 7 software was used for data entry and cleaning and then data exported to SPSS version 21 software for further analysis. Logistic regression model was used to identify factors associated with outcome variable. Results:- Audiometric measurement revealed that the prevalence of noise induced hearing loss in Akaki Basic Metal Industry was 22% (95% CI 17- 27). Previous exposure of noise (AOR = 2.8, 95% CI: 1.032-7.923), service year 11-20 years (AOR = 2.3, 95% CI: 1.078- 6.262) and service years 21-30 years (AOR = 5.2, 95% CI: 2.317- 11.507) when compared with 1-10 years' service respectively were significantly associated with noise induced hearing loss. But, drinking alcohol (AOR= 1.6, 0.740-3.236) and being hypertensive (AOR = 1.7, CI: 0.800 – 3.776) respectively were not significantly associated with NIHL. The environmental noise level measurement was Mean (SD) of 89 + 13.65 dB A. Conclusion: - The prevalence of hearing loss in Akaki basic metal industry shows significant number with association of level of exposure, previously exposure to noise and duration of exposure. This shows as great effort is needed from administrative of the industry to provide appropriate hearing protective devices based on noise level of sections and change the behavior of workers towards using it, monitor noise level according to the country`s standard and installation of acoustics materials with in the industry to protect the health of workers from noise hazard.

Reanalysis of the $X(4140)$ as axialvector tetraquark state with QCD sum rules
Creators: name: Wang, Zhi-Gang
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this article, we take the $X(4140)$ as the diquark-antidiquark type $cs\bar{c}\bar{s}$ tetraquark state with $J^{PC}=1^{++}$, and study the mass and pole residue with the QCD sum rules in details by constructing two types interpolating currents. The numerical results $M_{X_{L,+}}=3.95\pm0.09\,\rm{GeV}$ and $M_{X_{H,+}}=5.00\pm0.10\,\rm{GeV}$ disfavor assigning the $X(4140)$ to be the $J^{PC}=1^{++}$ diquark-antidiquark type $cs\bar{c}\bar{s}$ tetraquark state. Moreover, we obtain the masses of the $J^{PC}=1^{+-}$ diquark-antidiquark type $cs\bar{c}\bar{s}$ tetraquark states as a byproduct. The present predictions can be confronted to the experimental data in the future.

description: The usual models for electrical spin manipulation in semiconductor quantum dots assume that the confinement potential is separable in the three spatial dimensions and that the AC drive field is homogeneous. However, the electric field induced by the gates in quantum dot devices is not fully separable and displays significant inhomogeneities. Here, we address the electrical manipulation of hole spins in semiconductor heterostructures subject to inhomogeneous vertical electric fields and/or in-plane AC electric fields. We consider Ge quantum dots electrically confined in a Ge/GeSi quantum well as an illustration. We show that the lack of separability between the vertical and in-plane motions gives rise to an additional spin-orbit coupling mechanism (beyond the usual linear and cubic in momentum Rashba terms) that modulates the principal axes of the hole gyromagnetic g-matrix. This non-separability mechanism can be of the same order of magnitude as Rashba-type interactions, and enables spin manipulation when the magnetic field is applied in the plane of the heterostructure even if the dot is symmetric (disk-shaped). More generally, we show that Rabi oscillations in strongly patterned electric fields harness a variety of g-factor modulations. We discuss the implications for the design, modeling and understanding of hole spin qubit devices.

subject: Dewey Decimal Classification::100 | Philosophie

description: Die doppelte Bedeutung von „objektiv“ im Ausdruck „objektive Nötigung“ ermöglicht Kant zu Beginn der "Kritik der praktischen Vernunft", das Sollen als Handlungsaufforderung durch unterschiedene Willensbestimmungen bei beiden Sorten von Imperativen zu nutzen. Einmal rührt die Nötigung zur Handlung von etwas anderem her – der Absicht, dem gewünschten Zweck oder nur der zu vermeidenden Sanktion – und einmal wird das endliche vernünftige Wesen durch das Allgemein-Subjektive in ihm selbst zum Handeln genötigt. Diese Interpretation kann klarer als die auf der früheren "Grundlegung zur Metaphysik der Sitten" basierenden sein, die immer vor der Unmöglichkeit steht, das unbedingte Sollen als durch irgendetwas bedingt zu denken.
Accessing the real part of the forward $J/ψ$-p scattering amplitude from $J/ψ$ photo-production on protons around threshold

description: We provide an updated analysis of the forward $J/ψ$-p scattering amplitude, relating its imaginary part to $γp \to J/ψp$ and $γp \to c \bar c X$ cross section data, and calculating its real part through a once-subtracted dispersion relation. From a global fit to both differential and total cross section data, we extract a value for the spin-averaged $J/ψ$-p s-wave scattering length $a_{ψp} = 0.046 \pm 0.005$ fm, which can be translated into a $J/ψ$ binding energy in nuclear matter of $B_ψ= 2.7 \pm 0.3$ MeV. We estimate the forward-backward asymmetry to the $γp \to e^- e^+ p$ process around the $J/ψ$ resonance, which results from interchanging the leptons in the interference between the $J/ψ$ production and the Bethe-Heitler mechanisms. We show that to good approximation this asymmetry depends linearly on $a_{ψp}$, and can reach values around -25% for forthcoming $J/ψ$ threshold production experiments at Jefferson Lab. Its measurement can thus provide a very sensitive observable for a refined extraction of $a_{ψp}$.
