Hydrodynamic Model of H$α$ Emission from Accretion Shocks of Proto-Giant Planet and Circumplanetary Disk

description: Recent observations have detected excess H$α$ emission from young stellar systems with an age of several Myr such as PDS 70. One-dimensional radiation-hydrodynamic models of shock-heated flows that we developed previously demonstrate that planetary accretion flows of $>$ a few ten km s$^{-1}$ can produce H$α$ emission. It is, however, a challenge to understand the accretion process of proto-giant planets from observations of such shock-originated emission because of a huge gap in scale between the circumplanetary disk (CPD) and the microscopic accretion shock. To overcome the scale gap problem, we combine two-dimensional, high-spatial-resolution global hydrodynamic simulations and the one-dimensional local radiation hydrodynamic model of the shock-heated flow. From such combined simulations for the protoplanet-CPD system, we find that the H$α$ emission is mainly produced in localized areas on the protoplanetary surface. The accretion shocks above CPD produce much weaker H$α$ emission (approximately 1-2 orders of magnitude smaller in luminosity). Nevertheless, the accretion shocks above CPD significantly affect the accretion process onto the protoplanet. The accretion occurs at a quasi-steady rate, if averaged on a 10-day timescale, but its rate shows variability on shorter timescales. The disk surface accretion layers including the CPD-shocks largely fluctuate, which results in the time-variable accretion rate and H$α$ luminosity of the protoplanet. We also model the spectral emission profile of the H$α$ line and find that the line profile is less time-variable, despite the large variability in luminosity. High-spectral resolution spectroscopic observation and monitoring will be key to reveal the property of the accretion process.

description: The main obstacle in exploiting the frequency data of $δ$ Sct stars is difficulty in mode identification. The $δ$ Sct oscillation spectra, unlike those of the Sun or white dwarfs, do not exhibit very regular patterns. Thus, the mode identification must rely on sophisticated methods, which involve combined multi-passband photometry and radial velocity data, with an unavoidable theoretical input from stellar atmosphere models. Moreover, there are serious uncertainties in theory of $δ$ Sct stars that have to be solved. Mode identification and determination of global and internal structure parameters for $δ$ Sct stars has to be done simultaneously. I describe in some detail the methodology and present some recent results we obtained concerning degrees of excited modes, global stellar parameters, and constraints on models of subphotospheric convection, as well as effect of rotational mode coupling.

description: We perform tunable resonant Raman scattering on 17 semiconducting and 7 metallic singly resonant single wall carbon nanotubes. The measured scattering cross-section as a function laser energy provides information about a tube's electronic structure, the lifetime of intermediate states involved in the scattering process and also energies of zone center optical phonons. Recording the scattered Raman signal as a function of tube location in the microscope focal plane allows us to construct two-dimensional spatial maps of singly resonant tubes. We also describe a spectral nanoscale artifact we have coined the "nano-slit effect".

description: Anticoagulant rodenticides are baited poisons used to control rodent infestations. Despite application restrictions, rodenticide use can result in accidental poisonings of non-target wildlife, including carnivores. These animals may die from rodenticide poisoning, but there may be subtle, sub-lethal effects as well, including poorer body condition and increased susceptibility to pathogens and parasites. Coyotes (Canis latrans) are adaptable carnivores that often thrive in urban areas, which may explain evidence of rodenticide exposure in southern California. However, little is known about the environmental factors that contribute to rodenticide exposure, or whether rodenticides have sub-lethal effects. I estimated rodenticide exposure using a liver assay and compared body condition and landscape patterns to determine the relationship with various measures of AR exposure: (1) AR compound frequency, (2) AR residue concentration, and (3) Residue concentration of individual compounds. Body condition analysis suggests a potential relationship between ARs and sub-lethal effects; however, these patterns were more pronounced for FGARs than for the more toxic SGARs. Additionally, landscape patterns suggest a higher risk of exposure to SGARs in natural, less urbanized areas, whereas FGAR exposure was linked to increased urbanization. Further research is needed to confirm the potential sub-lethal effects seen in my study. Lastly, current California legislation has significantly restricted public use of SGARs, but certain activities are exempt, which may continue to pose risks of non-target exposure. Given these findings, further research should explore how effective the restrictions will be in mitigating non-target exposure and the risk of sub- lethal effects.

Τέλος, αναδεικνύεται η φιλοσοφία της χαράς του φιλοσόφου-ποιητή, δηλαδή η αισιόδοξη στάση του απέναντι στον θάνατο και η ελπίδα που παρέχει στον άνθρωπο για έναν καλύτερο βίο.
description: This present master thesis aims to the parallel approach of the poetical and philosophical writing of Giorgos Sarantaris, in order to point out some important patterns of his whole thought. At first, it examines his poetical work like an uncommon lyrical diary, which shows the reflexion like an element of philosophy. Then, it searches the issues of memory, oblivion and time, which are unfolded in his poems and proses and are analyzed in his essays. In addition, it examines his occupation with the matter of language, where it gets clearer the interpenetration of philosophical thought and literature writing like a self-referential turn of the writer. Finally, brings out the philosophy of happiness of the philosophe-poet, i.e. his hopeful stance over death and the hope which gives to human for a better life.

description: A new mechanism of longitudinal confinement of optical energy via coupled plasmon modes is proposed in chains of noble metal nanoparticles embedded in a graded dielectric medium, which is analogous to the confinement of electrons in semiconductor quantum wells. In these systems, one can control the transmission of optical energy by varying the graded refractive index of the host medium or the separation between the nanoparticles to realize the photonic analogue of electronic transistors. Possible passband tunability by nanoparticle spacing and modulation of the refractive index in the host medium have been presented explicitly and compared favorably with numerical calculations.

description: In this paper we study quantum group deformations of the infinite dimensional symmetry algebra of asymptotically AdS spacetimes in three dimensions. Building on previous results in the finite dimensional subalgebras we classify all possible Lie bialgebra structures and for selected examples, we explicitly construct the related Hopf algebras. Using cohomological arguments we show that this construction can always be performed by a so-called twist deformation. The resulting structures can be compared to the well-known $κ$-Poincaré Hopf algebras constructed on the finite dimensional Poincaré or (anti) de Sitter algebra. The dual $κ$ Minkowski spacetime is supposed to describe a specific non-commutative geometry. Importantly, we find that some incarnations of the $κ$-Poincaré can not be extended consistently to the infinite dimensional algebras. Furthermore, certain deformations can have potential physical applications if subalgebras are considered. Since the conserved charges associated with asymptotic symmetries in 3-dimensional form a centrally extended algebra we also discuss briefly deformations of such algebras. The presence of the full symmetry algebra might have observable consequences that could be used to rule out these deformations. }

description: This paper is a continuation and a partial summary of our analysis of the pairing at a quantum-critical point (QCP) in a metal for a set of quantum-critical systems, whose low-energy physics is described by an effective model with dynamical electron-electron interaction $V(Ω_m) = ({\bar g}/|Ω_m|)^γ$ (the $γ$-model). Examples include pairing at the onset of various spin and charge density-wave and nematic orders and pairing in SYK-type models. In previous papers, we analyzed the physics for $γ<2$. We have shown that the onset temperature for the pairing $T_p$ is finite, of order ${\bar g}$, yet the gap equation at $T=0$ has an infinite set of solutions within the same spatial symmetry. As the consequence, the condensation energy $E_c$ has an infinite number of minima. The spectrum of $E_c$ is discrete, but becomes more dense as $γ$ increases. Here we consider the case $γ=2$. The $γ=2$ model attracted special interest in the past as it describes the pairing by an Einstein phonon in the limit when the dressed phonon mass $ω_D$ vanishes. We show that for $γ=2$, the spectrum of $E_c$ becomes continuous. We argue that the associated gapless "longitudinal" fluctuations destroy superconducting phase coherence at a finite $T$, such that at $0

description: In this short note, we answer a question of Martin and Sanders [Integr. Equ. Oper. Theory, 85 (2) (2016), 191-220] by showing the existence of disjoint frequently hypercyclic operators which fail to be disjoint weakly mixing and, therefore, fail to satisfy the Disjoint Hypercyclicity Criterion. We also show that given an operator $T$ such that $T \oplus T$ is frequently hypercyclic, the set of operators $S$ such that $T, S$ are disjoint frequently hypercyclic but fail to satisfy the Disjoint Hypercyclicity Criterion is SOT dense in the algebra of bounded linear operators.

description: Η ψηφιακή εποχή - η εποχή του διαδικτύου θεωρείται ως η εποχή κατά την οποία το κοινωνικό υποκείμενο αποδεσμεύεται από το βιολογικό του σώμα και αποκτά ψηφιακή υπόσταση. Στην διαδικασία ψηφιοποίησης του σπάει τα όρια του χωροχρόνου, τόσο σε επίπεδο της άμεσης διεπαφής, όσο και στο επίπεδο του διαμοιρασμού της πληροφορίας. Όμως η δομή του διαδικτύου καθορίζεται από την οικονομική-κοινωνική και πολιτική δομή της απτής υλικής ζωής. Δομή η οποία παράγει καταπίεση και αποξένωση. Κατά αυτόν τον τρόπο, στην κοινωνία του διαδικτύου, εμφανίζονται δύο αντιθετικές πλευρές. Από την μία εμφανίζονται πολιτικές σκληρής οικονομικής κεντροποίησης που παράγουν ανισότητα και ανισομερή ανταγωνισμό και υποστηρίζουν την ιδέα της λειτουργίας της αγοράς ως κράτος εν κράτει. Από την άλλη πλευρά μπορεί κάποιος να εντοπίσει μία τρόπο τινά ψηφιακή αντίδραση σε αυτές τις πολιτικές (π.χ. Hacktivism, κίνημα ελεύθερου λογισμικού). Αντίδραση δηλαδή, που εμπεριέχει απελευθερωτική δυνατότητα. Απελευθερωτική εννοώντας την ελευθερία του καθενός να επιλέγει να συνδιαλέγεται και να δημιουργεί της δομές αυτές που θα του επιφέρουν οφέλη για το ευρύ σύνολο. Δομές οι οποίες λειτουργούν πέρα από τα ιεραρχικά πλαίσια και την λογική της αγοράς. Αναλύοντας αυτές τις δύο πλευρές, η διπλωματική εργασία προτείνει ένα ψηφιακό διαδίκτυο αποκεντροποιημένο, μακριά από την λογική της αγοράς βασιζόμενο σε μία μορφή «παγκοσμιοποίησης από τα κάτω»
description: The Digital era- the era of the internet is considered as the age in which social subject escapes from its biological body and become digitalized. During the process of becoming digitalized, social subject breaks the space-time frames, both in terms of inter-communication and dissemination of information. Behind these terms, it is found that the structure of the internet is determined by the materialistic economic, social and political conditions of oppression and alienation. Thus, there are two sides of the Network society. On the one hand, there are politics of concentrated force, inequality, antagonistic exclusion, the market as state, hierarchies, and hypothetically horizontal (but still vertical) leadership. On the other hand, one can detect a kind of digital reaction (e.g. Hacktivism, free software movement) which subscribes to the politics of openness, diversity, inclusiveness and horizontal, non-hierarchical self-government clashes etc. Comparing both sides, the current thesis proposes that the network has to be decentralized, far from the logic of the market and rely upon the concept of ‘globalization from below’

Η ερευνητική προσπάθεια αυτή προσδιορίζει τα βασικά χαρακτηριστικά του αποστάτη, τραγικού, διφορούμενου βυρωνικού ήρωα. Με βάση το θεωρητικό υπόβαθρο της διακειμενικότητας, καθορίζει τη ζωτική επιρροή της Γοτθικής και της Ρομαντικής παράδοσης στη διαμόρφωση του βυρωνικού ήρωα, ειδικά για τις πτυχές της επιβλητικής εμφάνισης, της ηθικής αμφισημίας, της επαναστατικότητας και της μοιραίας αγάπης. Στη συνέχεια, ένα σημαντικό μέρος αυτής της μελέτης φιλοδοξεί να ανιχνεύσει εκδηλώσεις των βυρωνικών χαρακτηριστικών σε ευρέως γνωστούς χαρακτήρες από σύγχρονες κινηματογραφικές δημιουργίες, όπως τα: To Kοράκι, V for Vendetta, Star Wars και X-Men.

Τέλος, τεκμηριώνεται ο επίκαιρος και δημοφιλής χαρακτήρας αυτής της ιδιαίτερης δημιουργίας του Byron, όχι μόνο για την τέχνη του κινηματογράφου, αλλά και σε σχέση με την πολιτισμική συνείδηση του κοινού
description: Lord Byron’s extraordinary life and work has devised to literature the prototype of the dark hero that took his name. This thesis examines the basic characteristics of the renegade, tragic, ambiguous Byronic hero. Based on the theoretical background of intertextuality, it determines the vital influence of the Gothic and the Romantic tradition to the formulation of the Byronic hero, especially for the aspects of his imposing appearance, moral ambiguity, rebelliousness and fatal love. Furthemore, a significant part of this study aspires to trace manifestations of Byronic traits in well-known characters from contemporary cinematic creations, such as The Crow, V for Vendetta, Star Wars and X–Men. Lastly, a more thorough examination of cinematic characters originating from both earlier and contemporary literature such as Dracula and Harry Potter showcases the uses of the Byronic hero type for the roles of the flawed hero as well as the sympathetic villain. Finally, it substantiates the relevance and popularity of Byron’s singular creation, not only for the art of cinema, but also in with regard to the audience’s cultural conscience.

description: We report a study of spin dependent transport in a system composed of a quantum dot coupled to a normal metal lead and a ferromagnetic lead (NM-QD-FM). We use the master equation approach to calculate the spin-resolved currents in the presence of an external bias and an intra-dot Coulomb interaction. We find that for a range of positive external biases (current flow from the normal metal to the ferromagnet) the current polarization $\wp=(I_\uparrow-I_\downarrow)/(I_\uparrow+I_\downarrow)$ is suppressed to zero, while for the corresponding negative biases (current flow from the ferromagnet to the normal metal) $\wp$ attains a relative maximum value. The system thus operates as a rectifier for spin--current polarization. This effect follows from an interplay between Coulomb interaction and nonequilibrium spin accumulation in the dot. In the parameter range considered, we also show that the above results can be obtained via nonequilibrium Green functions within a Hartree-Fock type approximation.

description: Global 21cm experiments aim to measure the sky averaged HI absorption signal from cosmic dawn and the epoch of reionisation. However, antenna chromaticity coupling to bright foregrounds can introduce distortions into the observational data of such experiments. We demonstrate a method for guiding the antenna design of a global experiment through data analysis simulations. This is done by performing simulated observations for a range of inserted 21cm signals, then attempting to identify the signals with a data analysis pipeline. We demonstrate this method on five antennae that were considered as potential designs for the Radio Experiment for the Analysis of Cosmic Hydrogen (REACH); a conical log spiral antenna, an inverted conical sinuous antenna and polygonal-, square- and elliptical-bladed dipoles. We find that the log spiral performs significantly better than the other antennae tested, able to correctly and confidently identify every inserted 21cm signal. In second place is the polygonal dipole antenna, which was only unable to detect signals with both very low amplitudes of 0.05K and low centre frequency of 80MHz. The conical sinuous antenna was found to perform least accurately, only able to detect the highest amplitude 21cm signals, and even then with biases. We also demonstrate that, due to the non-trivial nature of chromatic distortion and the processes of correcting for it, these are not the results that could have been expected superficially from the extent of chromatic variation in each antenna.

Hunting the Scalar Glueball: Prospects for BES III

description: The search for the ground state scalar glueball G_0 is reviewed. Spin zero glueballs will have unique dynamical properties if the amplitude is suppressed by chiral symmetry, as it is to all orders in perturbation theory: for instance, mixing of G_0 with \bar qq mesons would be suppressed, radiative J/psi decay would be a filter for new physics in the spin zero channel, and the decay G_0 \to \bar KK could be enhanced relative to G_0 \to ππ. These properties are consistent with the identification of f_0(1710) as the largely unmixed ground state scalar glueball, while recent BES data implies that f_0(1500) does not contain the dominant glueball admixture. Three hypotheses are discussed: that G_0 is 1) predominantly f_0(1500) or 2) predominantly f_0(1710) or 3) is strongly mixed between f_0(1500) and f_0(1710).

description: The gamma/hadron separation in the imaging air Cherenkov telescope technique is based on differences between images of a hadronic shower and a gamma induced electromagnetic cascade. One may expect for a large telescope that a detection of hadronic events containing Cherenkov light from one gamma subcascade only is possible. In fact, simulations show that for the MAGIC telescope their fraction in the total protonic background is about 1.5% to 5.2% depending on the trigger threshold. It has been found that such images have small sizes (mainly below 400 photoelectrons) which correspond to the low energy primary gamma's (below 100 GeV). It is shown that parameters describing shapes of images from one subcascade have similar distributions to primary gamma events, so those parameters are not efficient in all methods of gamma selection. Similar studies based on MC simulations are presented also for the images from 2 gamma subcascades which are products of the same pi^0 decay. The ratio of the number of the expected background from false gamma and one pi^0 to the number of the triggered high energy photons from the Crab direction has been estimated for images with a small alpha parameter to show that the occurrence of this type of protonic shower is the reason for the difficulties with true gamma selection at low energies.

description: We present an empirical correction of sky coordinates of X-ray photons obtained with the XIS aboard the Suzaku satellite to improve the source position accuracy and restore the point-spread function (PSF). The XIS images are known to have an uncertainty in position of up to 1 arcmin, and to show considerable degradations of the PSF. These problems are caused by a drifting of the satellite attitude due to thermal distortion of the side panel 7, where the attitude control system is mounted. We found that the position error averaged over a pointing observation can be largely reduced by using the relation between the deviation of the source position in the DETX direction and the ecliptic latitude of the pointing target. We parameterized the wobbling of the source position synchronized with the satellite orbital period with temperatures of onboard radiators and elapsed time since the night-day transition of the spacecraft. We developed software, aeattcor, to correct the image drift using these parameters, and applied it to 27 point-source images. We show that the radius of the 90% error circle of the source position was reduced to 19 arcsec and the PSF was sharpened. These improvements have enhanced the scientific capability of the Suzaku XIS.

description: We investigate the synchronization transition of the modified Kuramoto model where the oscillators form a scale-free network with degree exponent $λ$. An oscillator of degree $k_i$ is coupled to its neighboring oscillators with asymmetric and degree-dependent coupling in the form of $\couplingcoeff k_i^{η-1}$. By invoking the mean-field approach, we determine the synchronization transition point $J_c$, which is zero (finite) when $η> λ-2$ ($η< λ-2$). We find eight different synchronization transition behaviors depending on the values of $η$ and $λ$, and derive the critical exponents associated with the order parameter and the finite-size scaling in each case. The synchronization transition is also studied from the perspective of cluster formation of synchronized vertices. The cluster-size distribution and the largest cluster size as a function of the system size are derived for each case using the generating function technique. Our analytic results are confirmed by numerical simulations.

description: We show that the quantum geometry of the Fermi surface can be numerically described by a 3-dimensional discrete quantum manifold. This approach not only avoids singularities in the Fermi sea, but it also enables the precise computation of the intrinsic Hall conductivity resolved in spin, as well as any other local properties of the Fermi surface. The method assures numerical accuracy when the Fermi level is arbitrarily close to singularities, and it remains robust when Kramers degeneracy is protected by symmetry. The approach is demonstrated by calculating the anomalous Hall and spin Hall conductivities of a 2-band lattice model of a Weyl semimetal and a full-band ab-initio model of zincblende GaAs.

description: 3. Results
On the Mearim River, one M. macrocephalus specimen was collected on the lower course of the river at Laje dos Currais, in the municipality of São Mateus, during the flood season, while two specimen was obtained on the middle course of the river in the town of Pedreiras during the dry (low water) season. The M. macrocephalus specimen was collected at the locality of Pé da Serra in the municipality of Caxias during the dry season.
The four M. macrocephalus specimens (Table 1) present a characteristic coloration pattern, with a darker superior half of the body, three large black spots on each flank, and dark lines between the rows of scales (Ramirez et al., 2017). The body is robust, and the mouth terminal, with three teeth in the pre-maxillary bone and three teeth in the dentary bone (Figure 2). The specimens have 42–43 scales in the lateral line, seven rows of scales between the lateral line and the origin of the dorsal fin, six rows of scales between the lateral line and the origin of the pelvic fin, and 16 rows of scales around the caudal peduncle. These characteristics, together with the morphometry of the specimens, are fully consistent with the descriptions of M. macrocephalus published Garavello and Britski (1988) and Britski et al. (1999), and leave no doubt with regard to the identity of the taxon.
Four COI sequences were obtained, one from the specimen collected from the Itapecuru River, and three from the specimens obtained from the basin of the Mearim River. Comparisons with the sequences available in the BOLDSystems database confirmed the morphological identification of the specimens.The COI sequences obtained from the specimens collected in the present study were more than 99% similar to that of M. macrocephalus from the basin of the Paraná River (Table 2). This value is well within the 2% threshold for the identification of fish species by DNA barcoding (Ward et al., 2009; April et al., 2011; Carvalho et al., 2011; Mabragaña et al., 2011; Castro Paz et al., 2014).

description: Let $M$ denote a two-dimensional Moore space (so $H_2(M; \Z) = 0$), with fundamental group $G$. The $M$-cellular spaces are those one can build from $M$ by using wedges, push-outs, and telescopes (and hence all pointed homotopy colimits). The question we address here is to characterize the class of $M$-cellular spaces by means of algebraic properties derived from the group $G$. We show that the cellular type of the fundamental group and homological information does not suffice, and one is forced to study a certain universal extension.

description: MnBi$_2$Te$_4$ (MBT) materials are promising antiferromagnetic topological insulators where field driven ferromagnetism is predicted to cause a transition between axion insulator and Weyl semimetallic states. However, the presence of antiferromagnetic coupling between Mn/Bi antisite defects and the main Mn layer can reduce the low-field magnetization, and it has been shown that such defects are more prevalent in the structurally identical trivial magnetic insulator MnSb$_2$Te$_4$ (MST). We use high-field magnetization measurements to show that the magnetization of MBT and MST occur in stages and full saturation requires fields of~$\sim$~60 Tesla. As a consequence, the low-field magnetization plateau state in MBT, where many determinations of quantum anomalous Hall state are studied, actually consists of ferrimagnetic septuple blocks containing both a uniform and staggered magnetization component.

description: Ein innovativer Ansatz verfolgt das Konzept diskontinuierliche SMC Verbunde lokal zu verstärken, um die mechanischen Eigenschaften von strukturellen Komponenten gezielt an ein Anforderungsprofil anpassen zu können. Die vorliegende Arbeit basiert auf einem ganzheitlichen Ansatz, der darauf abzielt Material-, Struktur- und Bauteileigenschaften eines hybriden kontinuierlich-diskontinuierlichen SMC Verbunds zu untersuchen. Innerhalb jeder Stufe werden dabei die Eigenschaften der individuellen sowie des hybriden Materials betrachtet, um geeignete Kriterien zur Bewertung eines Hybridisierungseffektes zu definieren. Der untersuchte kontinuierlich-diskontinuierliche SMC Verbund zeichnete sich durch ein verbessertes mechanisches Eigenschaftsspektrum, sowohl auf Proben-, Struktur- als auch auf Bauteilebene aus. Die elastischen Eigenschaften konnten im uniaxialen Lastfall mit Hilfe der Mischungsregel und klassischen Laminattheorie sehr präzise analytisch ermittelt werden. Schadensinitiierung des hybriden SMC Verbundes wurde primär von der kontinuierlichen Komponente bestimmt. Zwischenfaserbrüche sowie intra- und interlaminare Delamination traten als dominierende Schädigungsmechanismen auf. Pseudo-Delamination bestimmte das Versagen der diskontinuierlichen Komponente. Allgemein betrachtet ermöglicht die lokale Verstärkung einen vielversprechenden Ansatz, um Material-, Struktur- sowie Bauteileigenschaften gezielt auf einen vorherrschenden Lastfall abstimmen zu können und im Optimalfall ein Eigenschaftsprofil zu generieren, welches besser als die Summe der Eigenschaften der beiden individuellen Komponenten ist.

description: The measurement of the Higgs quartic coupling modifier between a Higgs boson pair and a vector boson pair, $κ_{2V}$, is expected to be achieved from vector-boson fusion (VBF) production of a Higgs boson pair. However, this process involves another unmeasured parameter, the trilinear Higgs self-coupling modifier $κ_{λ}$. A sensitivity analysis should target both parameters. Since the LHC cannot avoid the gluon fusion pollution, which becomes severe for non-SM $κ_{λ}$, an electron-proton collider is more appropriate for the comprehensive measurement. In this regard, we study the VBF production of a Higgs boson pair in the $b\bar{b}b\bar{b}$ final state at the LHeC and FCC-he. Performing detailed analysis using the simulated dataset, we devise the search strategy specialized at the LHeC and FCC-he and give a prediction for the sensitivity to both $κ_{2V}$ and $κ_{λ}$. We find that the two electron-proton colliders have high potential: the LHeC has similar exclusion prospects as the HL-LHC; the FCC-he is extremely efficient, excluding the parameter space outside $κ_{2V} \in [0.8, 1.2]$ and $κ_{λ}\in [1, 2.5]$ at 95% C.L. for the total luminosity of $10$ ab$^{-1}$ and 10% uncertainty on the background yields.
