description: In the first paper in this series, a class of observables that generalized the gravitational wave memory effect were introduced and given the name "persistent gravitational wave observables." These observables are all nonlocal in time, nonzero in spacetimes with gravitational radiation, and have an observable effect that persists after the gravitational waves have passed. In this paper, we focus on the persistent observable known as "curve deviation," and we compute the observable using the Bondi-Sachs approach to asymptotically flat spacetimes at the leading, nontrivial order in inverse Bondi radius. The curve deviation is related to the final separation of two observers who have an initial separation, initial relative velocity, and relative acceleration. The displacement gravitational wave memory effect is the part of the curve deviation that depends on the initial separation and is the entire contribution for initially comoving, inertial observers at large Bondi radius. The spin and center-of-mass memory effects are contained within the dependence of the curve deviation on the initial relative velocity, and the dependence of the curve deviation on relative acceleration contains observables distinct from these known memory effects. We find that the full curve deviation observable can be written in terms of differences in nonradiative data before and after the radiation (which we call the "charge" contribution), along with a nonlinear "flux" contribution that vanishes in the absence of gravitational radiation. This splitting generalizes the notion of "ordinary" and "null" memory that exists for the displacement, spin, and center-of-mass gravitational wave memory effects to the full curve deviation observable.

description: We use a simple one-dimensional parameterisation of timing properties to show that hard and hard-intermediate state transient black hole X-ray binaries with the same power-spectral shape have systematically harder X-ray power-law emission in higher-inclination systems. We also show that the power-spectral shape and amplitude of the broadband noise (with low-frequency quasi-periodic oscillations, QPOs, removed) is independent of inclination, confirming that it is well-correlated with the intrinsic structure of the emitting regions and that the "type C" QPO, which is inclination-dependent, has a different origin to the noise, probably geometric. Our findings suggest that the power-law emission originates in a corona which is flattened in the plane of the disc, and not in a jet-like structure which would lead to softer spectra at higher inclinations. However, there is tentative evidence that the inclination-dependence of spectral shape breaks down deeper into the hard state. This suggests either a change in the coronal geometry and possible evidence for contribution from jet emission, or alternatively an even more optically thin flow in these states.

description: Background: The prevalence of mental disorders among asylum seekers and refugees is elevated compared to the general population. The importance of post-migration living difficulties (PMLDs), stressors faced after displacement, has recently been recognized due to research demonstrating their moderating role of on mental health outcomes. Traditionally, PMLDs were investigated as count variables or latent variables, disregarding plausible interrelationships among them. Objectives: To use network analysis to investigate the associations among PMLDs. Methods: Based on a cross-sectional measurement of seventeen PMLDs in a clinical sample of traumatized asylum seekers and refugees (N = 151), a partial correlation network was estimated, and its characteristics assessed. Results: The network consisted of 71 of the 120 possible edges. The strongest edge was found between ‘Communication difficulties’ and ‘Discrimination’. ‘Loneliness, boredom, or isolation’ had highest predictability. Conclusion: Our finding of an association between communication difficulties and discrimination has been documented before and is of importance given the known negative impact of discrimination on mental and physical health outcomes. The high predictability of isolation is indicative of multiple associations with other PMLDs and highlights its importance among the investigated population. Our results are limited by the cross-sectional nature of our study and the relatively modest sample size. This study network analytic study explored interrelations among postmigration living difficulties in refugees and asylum seekers.Dense interrelations among PMLDs were unveiled with the edge between ‘Communication difficulties’ and ‘Discrimination’ being the strongest.

Evaluation of the Legal Institutions of Diversion, Transfer, Storage, and Distribution of Water in Kentucky
Creators: name: Tarlock, A. Dan
Publisher: name: Kentucky Water Resources Research Institute, University of Kentucky
Year: 1968

description: Abstract:
In 1966 Kentucky enacted a water use regulation statute which makes :important modifications in the common law doctrine of riparian rights by authorizing the state to grant permits for the use of water. The permit system is primarily designed to allow the state to gather the information necessary to conduct long range planning studies. However, the permit system can also be used to apportion water among competing users. The report examined the common law of riparian rights to determine how KRS Ch. 151 had modified it and analyzed some of the legal problems which could arise in the administration of the statute. The standards for granting or denying a permit were examined in light of the purpose of Chapter 151. Important common law modifications such as the abolition of the watershed limitation were considered. The procedural rights of applicants and third parties effected by the issuance of a permit were criticized because they do not provide an adequate hearing and notice procedure. The constitutional questions raised by the failure of the Chapter expressly to protect prior vested rights were considered. The report concludes with an examination of some emerging problems caused by the increased use of the state's water for recreation.

description: Background: Child maltreatment (CM), particularly in institutional contexts, can affect the development of post-traumatic stress disorder (PTSD). Research suggests that factors during CM (e.g. severity, variety, duration) and in the aftermath of CM (e.g. stressful life events, and social acknowledgement, i.e. the degree to which an individual feels validated and supported following a traumatic event) can explain some of the heterogeneity in PTSD development. However, there is a lack of research on long-term correlates of CM and mitigating factors, with only a few studies having been conducted with older survivors of institutional upbringing. Such research is relevant, given the long-term associations between CM and the older age status of many survivors. Objective: The current study examined the link between CM and PTSD in older individuals with a history of institutional upbringing (risk group; RG) and a matched control group (CG). Differences in stressful life events and social acknowledgement were also investigated. Method: Participants were n = 116 RG (Mage = 70.25 years, 41% female) and n = 122 CG (Mage = 70.71 years, 51% female). Data was assessed using self-report questionnaires and a clinical interview. Results: The RG reported higher levels of exposure to CM. Lifetime PTSD showed a bigger association with the level of exposure to CM, compared to having an institutional upbringing. Participants with higher CM levels reported more stressful life events. High levels of social acknowledgement mediated the relationship between CM and PTSD in the CG. Conclusions: Exposure to CM had a stronger association with PTSD than a history of institutional upbringing. In the CG, the survivors’ perception of social acknowledgement ameliorated lifetime PTSD to a small extent. A critical issue for policy makers should be to enhance safeguarding measures against CM exposure, not only in institutional contexts, but also more generally, given the link to PTSD. In the present study individuals with a history of institutional upbringing reported high levels of child maltreatment.Furthermore, social acknowledgement was found to be meaningfully associated with post-traumatic stress disorders in child maltreatment survivors. In the present study individuals with a history of institutional upbringing reported high levels of child maltreatment. Furthermore, social acknowledgement was found to be meaningfully associated with post-traumatic stress disorders in child maltreatment survivors.

description: In this paper we study the conjugacy problem in polycyclic groups. Our main result is that we construct polycyclic groups $G_n$ whose conjugacy problem is at least as hard as the subset sum problem with $n$ indeterminates. As such, the conjugacy problem over the groups $G_n$ is NP-complete where the parameters of the problem are taken in terms of $n$ and the length of the elements given on input.
Hunting $\varepsilon$: The origin and validity of quasi-steady-state reductions in enzyme kinetics

description: The estimation of the kinetic parameters requires the careful design of experiments under a constrained set of conditions. Many estimates reported in the literature incorporate protocols that leverage simplified mathematical models known as quasi-steady-state reductions. Such reductions often - but not always - emerge as the result of a singular perturbation scenario. However, the utilization of the singular perturbation reduction method requires knowledge of a dimensionless parameter, $\varepsilon$, that is proportional to the ratio of the reaction's fast and slow timescales. Using techniques from differential equations, Fenichel theory, and center manifold theory, we derive the appropriate $\varepsilon$ whose magnitude regulates the validity of the quasi-steady-state reduction employed in the reported experimental procedures for intermolecular autocatalytic zymogen activation reaction. Although the model equations are two-dimensional, the fast/slow dynamics are rich. The phase plane exhibits a dynamic transcritical bifurcation point in a particular singular limit. The existence of such a bifurcation is relevant, because the critical manifold losses normal hyperbolicity and classical Fenichel theory is inapplicable. Furthermore, we show that in some cases chemical reversibility can be interpreted dynamically as an imperfection, since the presence of reversibility can destroy the bifurcation structure present in the singular limit. We show that the reduction method by which QSS reductions are justified can depend on the path taken in parameter space. Specifically, we show that the standard quasi-steady-state reduction for this reaction is justifiable by center manifold theory in one limit, and via Fenichel theory in a different limit.

description: We study the fluctuations of random surfaces on a two-dimensional discrete torus. The random surfaces we consider are defined via a nearest-neighbor pair potential which we require to be twice continuously differentiable on a (possibly infinite) interval and infinity outside of this interval. No convexity assumption is made and we include the case of the so-called hammock potential, when the random surface is uniformly chosen from the set of all surfaces satisfying a Lipschitz constraint. Our main result is that these surfaces delocalize, having fluctuations whose variance is at least of order $\log n$, where $n$ is the side length of the torus. We also show that the expected maximum of such surfaces is of order at least $\log n$. The main tool in our analysis is an adaptation to the lattice setting of an algorithm of Richthammer, who developed a variant of a Mermin-Wagner-type argument applicable to hard-core constraints. We rely also on the reflection positivity of the random surface model. The result answers a question mentioned by Brascamp, Lieb and Lebowitz 1975 on the hammock potential and a question of Velenik 2006.

Evaluation of Runoff Coefficients From Small Natural Drainage Areas

Publisher: name: Kentucky Water Resources Research Institute, University of Kentucky
Year: 1968

description: Abstract:
The Kentucky Department of Highways, as do most other agencies which build small drainage structures, estimates flood peaks as the product of a runoff coefficient, a rainfall intensity, and the drainage area, Available procedures were applied to 39 gaged watersheds in and near Kentucky and compared with the results of frequency analysis of historical stream gage records. The methods consistently underestimated the flood peak.
Therefore, a more intensive study (using the Stanford Watershed Model) of the runoff coefficient was undertaken by dividing it into overland flow and streamflow components. A set of curves was developed based on the 50-year event at Lexington, Kentucky, to estimate the peak rate of overland flow as a fraction of rainfall intensity from five measurable watershed characteristics (soil depth, permeability, overland slope, impervious area, and soil surface exposure). The streamflow component was not studied.
A study was made of the variation of the runoff coefficient with mean annual rainfall, rainfall intensity, and frequency. The investigation was based on applying the Stanford Watershed Model to six hourly-rainfall records. The result was a set of correction factors to apply to the overland flow values estimated from watershed characteristics.

We also describe our plan to consult with community organizations for people living with disability to determine what considerations for optimizing participation of members of underrepresented groups are not captured in the current review findings. In doing so, the proposed review’s findings will guide subsequent development and evaluations of exercise programs virtually delivered to adults with mobility limitations.

description: Background: While Internet- and mobile-based interventions (IMIs) are potential options to increase the access to evidence-based therapies for post-traumatic stress disorder (PTSD), comprehensive knowledge on their working mechanisms is still scarce. Objective: We aimed to evaluate studies investigating the efficacy and mechanisms of change in IMIs for adults with PTSD. Method: In this systematic review and meta-analysis (PROSPERO CRD42019130314), five databases were consulted to identify relevant studies, complemented by forward (i.e. citation search) and backward (i.e. review of reference lists from included studies) searches. Randomized controlled trials (RCTs) investigating the efficacy of IMIs compared to active controls, as well as component and mediation studies were included. Two independent reviewers extracted the data and assessed the risk of bias and requirements for process research. Random-effects meta-analyses on PTSD symptom severity as primary outcome were conducted and further information was synthesized qualitatively. Results: In total, 33 RCTs were included (N = 5421). The meta-analysis comparing IMIs to non-bonafide active controls yielded a significant standardized mean difference (SMD) of −0.36 (95%CI −0.53 to −0.19) favouring IMIs. Although meta-analytic pooling was not possible for the component and mediation studies, evidence suggests no differential effects regarding PTSD symptom reduction between different levels of support and personalization and between different types of exposure. Moreover, mediation studies revealed significant intervening variable effects for self-efficacy beliefs, perceived physical impairment, social acknowledgement, and trauma disclosure. Conclusions: Results indicate that IMIs for PTSD are superior to active controls. Furthermore, findings may contribute to the development of new interventions by outlining important directions for future research (e.g. regarding requirements for process research) and highlighting potential mechanisms of change (i.e. self-efficacy, perceived physical impairment, social acknowledgement, and trauma disclosure). • Knowledge on mechanisms of change in psychothera-pies is crucial as it contributes to intervention development and improved outcomes. • This review suggests that digital interventions for PTSD are efficacious; yet, more studies are needed to enhance understanding on how they work.

description: Boson-Sampling holds the potential to experimentally falsify the Extended Church Turing thesis. The computational hardness of Boson-Sampling, however, complicates the certification that an experimental device yields correct results in the regime in which it outmatches classical computers. To certify a boson-sampler, one needs to verify quantum predictions and rule out models that yield these predictions without true many-boson interference. We show that a semiclassical model for many-boson propagation reproduces coarse-grained observables that were proposed as witnesses of Boson-Sampling. A test based on Fourier matrices is demonstrated to falsify physically plausible alternatives to coherent many-boson propagation.

description: Tuberculosis (TB) is a global health challenge; therefore, there is an urgent requirement to develop a novel and more effective anti-TB therapeutic. This study targeted the isocitrate lyase (ICL) protein due to its pivotal role in the pathogenicity of Mycobacterium tuberculosis (Mtb). Virtual screening of 8752 bioactive compounds used an ML-based QSAR model and molecular docking. ADMET testing was performed on the top three hits to identify the compound most closely mimicking a drug molecule. The top hits, 648 and 2785758, showed high binding affinity towards ICL with −7.3 and −7 kcal/mol, comparable to the control. These molecules also showed strong binding with the residue Asp108, which plays a vital role in ICL activity. Molecular dynamics simulations showed stability for 648 and 2785758, comparable to the control compound used in this study. It was found that 648 bound to the protein maintained the RMSD constant and consistent at 0.3 nm for a complete 100 ns simulation. 2785758 showed a comparable RMSD trend to the control. Both 648 and 2785758 showed high RMSF for critical residue Asp108. Further, PCA and FEL confirmed the formation of a stable complex. MM/GBSA estimations of binding free energy indicated that compounds 648 had an elevated level of stability (ΔGTOTAL = −28.11 kcal/mol) and 2785758 (ΔGTOTAL = −21.05 kcal/mol). This study suggests that compounds 648 and 2785758 can potentially affect the activity of ICL, leading to its inactivation and ultimately preventing the progression of tuberculosis.

description: This paper introduces the emerging field of astrobotics, that is, a recently-established branch of robotics to be of service to astrophysics and observational astronomy. We first describe a modern requirement of dark matter studies, i.e., the generation of the map of the observable universe, using astrobots. Astrobots differ from conventional two-degree-of-freedom robotic manipulators in two respects. First, the dense formation of astrobots give rise to the extremely overlapping dynamics of neighboring astrobots which make them severely subject to collisions. Second, the structure of astrobots and their mechanical specifications are specialized due to the embedded optical fibers passed through them. We focus on the coordination problem of astrobots whose solutions shall be collision-free, fast execution, and complete in terms of the astrobots' convergence rates. We also illustrate the significant impact of astrobots assignments to observational targets on the quality of coordination solutions To present the current state of the field, we elaborate the open problems including next-generation astrophysical projects including 20,000 astrobots, and other fields, such as space debris tracking, in which astrobots may be potentially used

description: Diese Studie untersucht Belastungsfaktoren und Entlastungsfaktoren, die in Zusammenhang mit der COVID-19 Pandemie auf Menschen im Alten- und Pflegekontext einwirken, sowie die Auswirkungen der Impfung auf das psychische Wohlbefinden dieser Personengruppen. Es wurden Expert*inneninterviews mit acht Beschäftigten von Alten- und Pflegeheimen in Österreich durchgeführt und anschießend mithilfe qualitativer Inhaltsanalyse nach Mayring (2015) ausgewertet, woraus sich 75 Kategorien ergaben. Im Bereich der Belastungen spielten Personalmangel, Mangelnde Wertschätzung und die Umsetzbarkeit Maßnahmen eine Rolle. Entlastend wirkten beispielsweise Gewöhnung, Solidarität im Kollegium und Liebe zum Beruf. Als positiv an der Impfung wurde die dadurch entstandene Sicherheit genannt und die Möglichkeit einen Beitrag leisten zu können. Die Gruppe der älteren Menschen war hauptsächlich durch Regelungen, die die Kommunikation einschränkten und den direkten Körperkontakt verboten belastet, wohingegen Technische Hilfsmittel Belastung entgegenwirken konnte. Insgesamt verdeutlichen die Ergebnisse der Studie den Bedarf der Arbeitenden im Alten- und Pflegekontext, ausreichend unterstützt und wertgeschätzt zu werden, damit sie auch in Zeiten der COVID-19 Pandemie ihre Arbeit ohne zusätzliche Belastungen durchführen können.
description: This study examines stressors and resources and their potential influences on the psychological well-being of people in nursing home settings as well as the impact of the vaccination in the context of the COVID-19 pandemic on those groups. Therefore, interviews were conducted with eight experts who were all working in nursing homes in Austria. Mayring´s qualitative content analysis (2015) was used to examine the results, which could be grouped in 75 categories. Those included staff shortage, lacking appreciation and the feasibility of the restrictions on the level of stressors. As resources habituation, solidarity among co-workers and job affinity were for example mentioned. Positive impacts in terms of the vaccination were security and the ability to contribute. The group of elderly people, living in the nursing homes, was negatively affected by restrictions concerning interferences with communication and physical contact. Technical devices were able to help reduce stress. All in all, it became obvious that people working in nursing homes need more and sufficient support, as well as appreciation for what they do to stay healthy and keep on working in times of the pandemic.

description: We investigate some cosmological consequences of a vector-tensor theory where an Abelian symmetry in the vector sector is slightly broken by a mass term and by ghost-free derivative self-interactions. When studying cosmological expansion in the presence of large bare cosmological constant $Λ_{cc}$, we find that the theory admits branches of de Sitter solutions in which the scale of the Hubble parameter is inversely proportional to a power of $Λ_{cc}$. Hence, a large value of $Λ_{cc}$ leads to a small size for the Hubble scale. In an appropriate limit, in which the symmetry breaking parameters are small, the theory recovers the Abelian symmetry plus an additional Galileon symmetry acting on the longitudinal vector polarization. The approximate Galileon symmetry can make the structure of this theory stable at the energy scales we are interested in. We also analyze the dynamics of linearized cosmological fluctuations around the de Sitter solutions, showing that no manifest instabilities arise, and that the transverse vector polarizations become massless around these configurations.

description: Larvae of the black soldier fly (Hermetia illucens, BSFL) are rich in valuable nutrients and offer a promising alternative protein source for animal feeds. Nonetheless, there is a pressing need to improve both the productivity and quality of BSFL to ensure the viability of BSFL products and facilitating the industrial production. To fulfil the needs of different animals, it is necessary to adjust the profile of essential amino acids (EAAs) in BSFL. Insects excrete surplus nutrients to maintain homeostasis; AAs are excreted by nutrient AA transporters (NATs) in the Malpighian tubules. We aimed to modify the composition of essential AAs by silencing the NAT in Malpighian tubules of BSFL (HiNATt). Silencing HiNATt resulted in a 77.3% increase in the total AA content while 56.2% decrease in body weight. Notably, the contents of some valuable essential AAs were strongly increased (histidine, 256.8%; valine, 198.1% in total compared to the intact larva). These results suggest that inhibiting the HiNATt function could modify the amount of accumulated EAAs. This finding opens a new avenue for producing of BSFL with increased nutritional value as an alternative protein source.

description: We study the tilt of the primordial gravitational waves spectrum. A hint of blue tilt is shown from analyzing the BICEP2 and POLARBEAR data. Motivated by this, we explore the possibilities of blue tensor spectra from the very early universe cosmology models, including null energy condition violating inflation, inflation with general initial conditions, and string gas cosmology, etc. For the simplest G-inflation, blue tensor spectrum also implies blue scalar spectrum. In general, the inflation models with blue tensor spectra indicate large non-Gaussianities. On the other hand, string gas cosmology predicts blue tensor spectrum with highly Gaussian fluctuations. If further experiments do confirm the blue tensor spectrum, non-Gaussianity becomes a distinguishing test between inflation and alternatives.

description: Background: Meta-analytic results indicate that posttraumatic stress disorder (PTSD) is associated with hypoactivation of the medial prefrontal cortex (mPFC), hyperactivation of the amygdala, and volume reductions of the hippocampus. Effective psychotherapeutic treatments were hypothesized to normalize these neural patterns via upregulation of prefrontal structures, which in turn downregulate limbic regions. Objective: To gain a sound understanding of the effects of successful psychotherapy on the brain, neural changes from pre- to post-treatment in PTSD patients will be aggregated. Method: A systematic literature search identified 24 original studies employing structural or functional MRI measurements both before and after treatment of patients diagnosed with PTSD. Results: In conjunction, the review returned little evidence of an activation increase in the mPFC/rostral anterior cingulate cortex (rACC) following successful treatment. Five out of 12 studies observed such an increase (especially during emotion processing tasks), albeit in partially non-overlapping brain regions. Conversely, neither the putative related activation decrease in the amygdala nor volumetric changes or altered activation during the resting state could be convincingly established. Conclusion: Successful psychological treatments might potentially work via upregulation of the mPFC, which thus may be involved in symptom reduction. However, the role of the amygdala in recovery from PTSD remains unclear. There is currently no indication that the various PTSD treatment approaches employed by the reviewed studies differ regarding their action mechanisms, but further research on this topic is needed. There is little evidence for an activation increase in mPFC/rACC following successful PTSD treatment.Most studies detected no significant activation changes in amygdala, insula, or hippocampus.There is no consistent evidence for post-treatment volume changes in any brain region. There is little evidence for an activation increase in mPFC/rACC following successful PTSD treatment. Most studies detected no significant activation changes in amygdala, insula, or hippocampus.

title: Geschichten und Geschichte - die Franzensburg im Schlosspark Laxenburg bei Wien
Creators: name: Müller-Angerer, Ursula
Year: 2023

description: Der sogenannte „Rittergau“ im Schlosspark Laxenburg bei Wien gilt als eines der bedeutendsten Beispiele österreichischer Gartenkunst des frühen 19. Jahrhunderts. Unter Kaiser Franz II. /I. (1768-1835) ab 1798 erbaut, nimmt er im Schlosspark eine vom restlichen Areal gesonderte Stellung mit einer in sich geschlossenen Programmatik ein. Bestehend aus „mittelalterlich“ konnotierten Bauten und mit der Franzensburg als Herzstück vereint die Anlage eine Vielzahl an Bedeutungsebenen zwischen romantischer Mittelalterfantasie, habsburgischem Denkmal, Vorläufer eines Freilichtmuseums und Kunstwerk. Ausgehend von gängigen Assoziations- und Interpretationsmustern, die dem Rittergau in zeitgenössischen Reiseberichten, wissenschaftlichen Texten und bildlichen Darstellungen zugesprochen werden, kontextualisiert und untersucht diese Arbeit die Mechanismen dieser Erzählstrukturen innerhalb der Anlage. Unterschiedliche Sichtweisen und Lesarten werden dabei wertfrei vor- und gegenübergestellt sowie die Franzensburg selbst als eigenständiges Kunstwerk mit ebensolcher Narration berücksichtigt.
description: The so-called „Rittergau“ in the Castle Gardens of Laxenburg near Vienna is known as one of the most significant examples of garden design from early 19th century Austria. Built under emperor Francis II. /I. (1768-1835) from 1798 onward, this area separates itself from the rest of the gardens not only in looks, but also in iconology. With its seemingly „medieval“ buildings, of which Franzensburg Castle is the most notable, its meanings range from romantic old age fantasy to habsburgian memorial, from museum to artwork. This paper contextualises the most common interpretations by contemporary visitors, historians and artists, while also analysing the mechanisms of these narratives. Different perspectives and readings are treated in an unbiased manner and provide a base for further iconological discussions regarding the artistic value and narration of Franzensburg Castle itself.
Vacuum Insertion Approximation and the $ΔI=1/2$ rule:a lattice QCD test of the naïve factorization hypothesis for $K$, $D$, $B$ and static mesons

description: Motivated by a recent paper by the RBC-UKQCD Collaboration, which observes large violations of the naïve factorization hypothesis in $K \to ππ$ decays, we study in this paper the accuracy of the Vacuum Insertion Approximation (VIA) for the matrix elements of the complete basis of four fermion $ΔF=2$ operators. We perform a comparison between the matrix elements in QCD, evaluated on the lattice, and the VIA predictions. We also investigate the dependence on the external meson masses by computing matrix elements for $K$, $D_s$, $B_s$ and static mesons. In commonly used renormalization schemes, we find large violations of the VIA in particular for one of the two relevant Wick contractions in the kaon sector. These deviations, however, decrease significantly as the meson mass increases and the VIA predictions turn out to be rather well verified for B-meson matrix elements and, even better, in the infinite mass limit.

Collinear approach for top quark production at ep colliders

description: An approximately analysis study of the collinear approach for $t\overline{t}$ production at the Future Circular Collider hadron-electron (FCC-he) and the Large Hadron electron Collider (LHeC) is performed. To study heavy quark production processes, the collinear generalized double asymptotic scaling (DAS) approach in a wide rang of $Q^{2}$ is used. The reduced cross sections for top quark pair production at the FCC-he (for $Q^{2}{\geq}m^{2}_{t}$) and LHeC (for $Q^{2}{\leq}m^{2}_{t}$) center-of-mass energies at the high inelasticity are derived. These results may be considering for both the future collider experiments at center-of-mass energy frontier and the improvement of the phenomenological models on kinematics of low values of the Bjorken variable $x$. The evolution of the gluon density for heavy-quark production in DIS is obtained at low $x$ to include effects of heavy-quark masses. A nonlinear modification of these results shown that the nonlinear corrections, with respect to the top quark mass, are very small for $Q^{2}{\propto}m^{2}_{t}$.
