description: Combining gravity with quantum mechanics remains one of the biggest challenges of physics. In the past years, experiments with opto-mechanical systems have been proposed that may give indirect clues about the quantum nature of gravity. In a recent variation of such tests [D. Carney et al., Phys.Rev.X Quantum 2, 030330 (2021)], the authors propose to gravitationally entangle an atom interferometer with a mesoscopic oscillator. The interaction results in periodic drops and revivals of the interferometeric visibility, which under specific assumptions indicate the gravitational generation of entanglement. Here we study semi-classical models of the atom interferometer that can reproduce the same effect. We show that the core signature -- periodic collapses and revivals of the visibility -- can appear if the atom is subject to a random unitary channel, including the case where the oscillator is fully classical and situations even without explicit modelling of the oscillator. We also show that the non-classicality of the oscillator vanishes unless the system is very close to its ground state, and even when the system is in the ground state, the non-classicality is limited by the coupling strength. Our results thus indicate that deducing entanglement from the proposed experiment is very challenging, since fulfilling and verifying the non-classicality assumptions is a significant challenge on its own right.

description: Recent learning-based image classification and speech recognition approaches make extensive use of attention mechanisms to achieve state-of-the-art recognition power, which demonstrates the effectiveness of attention mechanisms. Motivated by the fact that the frequency and time information of modulated radio signals are crucial for modulation mode recognition, this paper proposes a time-frequency attention mechanism for a convolutional neural network (CNN)-based modulation recognition framework. The proposed time-frequency attention module is designed to learn which channel, frequency and time information is more meaningful in CNN for modulation recognition. We analyze the effectiveness of the proposed time-frequency attention mechanism and compare the proposed method with two existing learning-based methods. Experiments on an open-source modulation recognition dataset show that the recognition performance of the proposed framework is better than those of the framework without time-frequency attention and existing learning-based methods.

description: Modern software development requires developers to find and effectively utilize new APIs and their documentation, but documentation has many well-known issues. Despite this, developers eventually overcome these issues but have no way of sharing what they learned. We investigate sharing this documentation-specific information through \textit{annotations}, which have advantages over developer forums as the information is contextualized, not disruptive, and is short, thus easy to author. Developers can also author annotations to support their own comprehension. In order to support the documentation usage behaviors we found, we built the Adamite annotation tool, which supports features such as multi-anchoring, annotation types, and pinning. In our user study, we found that developers are able to create annotations that are useful to themselves and are able to utilize annotations created by other developers when learning a new API, with readers of the annotations completing 67% more of the task, on average, than the baseline.

description: We present a procedure for finding the exact solution to the linear-response Boltzmann equation for two-dimensional anisotropic systems and demonstrate it on examples of non-crystalline anisotropic magnetoresistance in a system with spin-orbit interaction. We show that two decoupled integral equations must be solved in order to find the non-equilibrium distribution function up to linear order in the applied electric field. The examples are all based on the Rashba system with charged magnetic scatterers, a system where the non-equilibrium distribution function and anisotropic magnetoresistance can be evaluated analytically. Exact results are compared to earlier widely-used approximative approaches. We find circumstances under which approximative approaches may become unreliable even on a qualitative level.

description: We study compactifications on ${\rm AdS}_3\times S^3$ and deformations thereof. We exploit the triality symmetry of the underlying duality group ${\rm SO}(4,4)$ of three-dimensional supergravity in order to construct and relate new consistent truncations. For non-chiral $D=6$, ${\cal N}_{\rm 6d}=(1,1)$ supergravity, we find two different consistent truncations to three-dimensional supergravity, retaining different subsets of Kaluza-Klein modes, thereby offering access to different subsectors of the full nonlinear dynamics. As an application, we construct a two-parameter family of ${\rm AdS}_3\times M^3$ backgrounds on squashed spheres preserving ${\rm U}(1)^2$ isometries. For generic value of the parameters, these solutions break all supersymmetries, yet they remain perturbatively stable within a non-vanishing region in parameter space. They also contain a one-parameter family of ${\cal N}=(0,4)$ supersymmetric ${\rm AdS}_3\times M^3$ backgrounds on squashed spheres with ${\rm U}(2)$ isometries. Using techniques from exceptional field theory, we determine the full Kaluza-Klein spectrum around these backgrounds.

description: A family of deformed black branes is employed to examine the confinement/deconfinement phase transition in AdS/QCD. The holographic entanglement entropy (HEE) plays the role of the order parameter driving the confinement/deconfinement phase transition. The binding energy of quark-antiquark bound states and the critical length that makes a null variation of the HEE, together with the critical temperature separating the deconfined quark-gluon plasma to the confined hadronic phase, are discussed in the deformed black brane background, matching current experimental hadronic data.

description: We study the asymptotic behavior of a special smooth solution y(x,t) to the second member of the Painleve I hierarchy. This solution arises in random matrix theory and in the study of Hamiltonian perturbations of hyperbolic equations. The asymptotic behavior of y(x,t) if x\to \pm\infty (for fixed t) is known and relatively simple, but it turns out to be more subtle when x and t tend to infinity simultaneously. We distinguish a region of algebraic asymptotic behavior and a region of elliptic asymptotic behavior, and we obtain rigorous asymptotics in both regions. We also discuss two critical transitional asymptotic regimes.

description: We consider the spinorial wave equations, namely the Dirac and the Klein-Gordon equations, and greybody radiation in the NUT black hole spacetime. To this end, we first study the Dirac equation in NUT spacetime by using a null tetrad in the Newman-Penrose (NP) formalism. Next, we separate the Dirac equation into radial and angular sets. The angular set is solved in terms of associated Legendre functions. With the radial set, we obtain the decoupled radial wave equations and derive the one-dimensional Schrödinger wave equations together with effective potentials. Then, we discuss the potentials by plotting them as a function of radial distance in a physically acceptable region. We also study the Klein-Gordon equation to compute the greybody factors (GFs) for both bosons and fermions. The influence of the NUT parameter on the GFs of the NUT spacetime is investigated in detail.

In this Letter we show that for all ranges of normal and anomalous diffusion described by a Generalized Langevin Equation the Khinchin theorem holds.

Creatine kinase in Xenopus laevis development : changes in enzyme activity and isozyme patterns
Creators: name: Haswell, Polly
Publisher: name: University of British Columbia
Year: 2010

description: The early developmental changes of creatine kinase have been described in Xenopus laevis, the South African clawed frog. The specific activity was low during early development and increased about 5-fold between stages 4-2 and 48. Isozyme I is present from the unfertilized egg to stage 42 (free-swimming larva), when isozyme II is first detected. Isozyme III first appeared in post-metamorphic frogs. Isozymes II and III have been localized in the muscle tissue, but isozyme II is absent in adult muscle tissue suggesting it may be a transient, embryonic form of CK. An attempt was made to induce the precocious appearance of isozyme III by treating premetamorphic tadpoles with triiodothyronine.

description: With the legacy of Spitzer and current advances in (sub)mm astronomy, a large number of 'transitional' disks has been identified which are believed to contain gaps or have developped large inner holes, some filled with dust. This may indicate that complex geometries may be a key feature in disk evolution that has to be understood and modeled correctly. The disk around LkCa 15 is such a disk, with a gap ranging from ~5 - 50 AU, as identified by Espaillat et al. (2007) using 1+1D radiative transfer modelling. To fit the SED, they propose 2 possible scenarios for the inner (<5 AU) disk - optically thick or optically thin - and one scenario for the outer disk. We use the gapped disk of LkCa 15 as a showcase to illustrate the importance of 2D radiative transfer in transitional disks, by showing how the vertical dust distribution in dust-filled inner holes determines not only the radial optical depth but also the outer disk geometry. We use MCMax, a 2D radiative transfer code with a self-consistent vertical structure, to model the SED. We identify two possible geometries for the inner and outer disk, that are both different from those in Espaillat et al. (2007). An inner disk in hydrostatic equilibrium reprocesses enough starlight to fit the near infrared flux, but also casts a shadow on the inner rim of the outer disk. This requires the outer disk scale height to be large enough to rise out of the shadow. An optically thin inner disk does not cast such a shadow, and the SED can be fitted with a smaller outer disk scale height. For the dust in the inner regions to become optically thin however, the scale height would have to be so much larger than its hydrostatic equilibrium value that it effectively becomes a dust shell. It is currently unclear if a physical mechanism exists which could provide for such a configuration.

description: We present radial velocities of the double-lined spectroscopic binary NP Aqr. The radial velocities and the optical light curves obtained by Hipparcos and ASAS-3 are analyzed separately. The masses of the primary and secondary components have been found to be 1.65$\pm$0.09 and 0.99$\pm$0.05 M$_{\odot}$, respectively. The cross-correlation functions indicate triple peaks which show presence of a tertiary star. The spectroscopic properties of this additional component resemble to that of the primary star. The analysis of the light curves yielded that the more massive primary star fills its corresponding Roche lobe. The secondary component is at or near Roche lobe indicating a new $β$ Lyrae-type near-contact binary. The orbital inclination is about 40$^{\circ}$ and, therefore, the observed light variations are produced only by the proximity effects. Due to the absence of eclipses, the effective temperature of the secondary star and the radii of the components could not be determined accurately. We conclude that NP Aqr is a non-eclipsing double-lined spectroscopic binary with a distance of about 134$\pm$7 pc. The absolute parameters of the components are also compared with the evolutionary models. While the location of the primary star seems to be suitable with respect to its mass in the Hertzsprung-Russell diagram, the secondary component is located as if a star having a mass less than 0.6 M$_{\odot}$. This discrepancy is originated from very low effective temperature determined only from the light curve produced by proximity effects. The distance to the third star appears to be very close to that of the close binary which indicates that it may be dynamically bounded to the binary.

Zambia's Economic Puzzle: Decoding the Interplay of Sectoral Contributions, Demographics, Trade, and Resources

Year: 2025
Subjects: Economic Development, Sectoral Contributions, Demographic Trends, Trade Activities, Resource Access

description: This study provides a comprehensive analysis of Zambia's economic development by examining sectoral contributions, demographic changes, trade activities, and access to resources. Using descriptive statistics, correlation analysis and regression models on data from the World Bank database analyzed using Jamovi software, the study examines how these factors interact and influence Zambia's GDP and overall economic growth. The results reveal that while agriculture and manufacturing have historically contributed significantly to GDP, their relative importance has declined over time as GDP has increased, reflecting a clear structural shift in the economy. Conversely, the contribution of the services sector to GDP has increased substantially, underscoring its growing role in Zambia's economic framework. The study also shows a strong negative correlation between sectoral contributions (excluding services) and GDP, suggesting underlying inefficiencies or structural challenges within these sectors. Demographic trends, including fertility rates and population size, have a minimal impact on GDP growth, suggesting that other factors play a more important role in driving economic development. Trade activity shows that exports have a positive impact on GDP, while imports, although substantial in volume, have a weaker and statistically less significant impact on growth. This underscores the critical role of export performance in Zambia's economic progress. In addition, the study finds a strong positive relationship between increased access to electricity and life expectancy, suggesting that infrastructure improvements are key to improving the quality of life. Although GDP growth has a minimal direct effect on life expectancy or access to electricity, improved infrastructure is strongly associated with better health outcomes. Overall, the study highlights the need for policies that address sectoral imbalances, promote export growth, support the expanding services sector, and improve infrastructure to foster sustainable economic development. These findings provide valuable insights for policymakers and stakeholders as Zambia continues its economic transformation.

description: This study examines whether “Popular Reporting” enables universities to fulfil sustainability reporting guidelines while facilitating effective stakeholder engagement. Using the University of Turin as a case study, the research explores how this reporting approach addresses the dimensions of polycrisis by aligning institutional actions with stakeholder needs. The methodology involves the analysis of institutional documents, semi-structured interviews with governance representatives, sentiment analysis to identify key issues and an evaluation of the dialogic capacity of reporting to meet governance and stakeholder informational demands. The findings highlight that Popular Reporting provides a concise yet comprehensive representation of institutional activities and their broader context, ensuring the inclusion of stakeholder-relevant topics. By adhering to the "University Sustainability Report" guidelines and RUS-GBS standards, this dynamic reporting approach bridges the gap between traditional social reporting and the complex requirements of sustainability communication. The study underscores the practical value of Popular Reporting as a dialogic tool that strengthens governance processes while fostering meaningful stakeholder relationships. Its implications extend beyond the University of Turin, suggesting broader applicability in academic institutions seeking to enhance accountability and address stakeholder sentiment. Future research could expand these insights to different contexts, further validating Popular Reporting as an effective mechanism for institutional sustainability and stakeholder engagement.

description: Transmissible spongiform encephalopathies (TSE) are neurodegenerative diseases caused by the conversion of the host-encoded cellular protein (PrPC) to a disease-associated isoform (PrPSc). The agent responsible for prion diseases may exist as different strains with specific biological and biochemical properties. According to the protein-only hypothesis, prion strain diversity is enciphered in PrPSc conformation. Molecular strain typing methods are based on the electrophoretic mobility of protease resistant core of PrPSc, on the susceptibility to protease digestion, on the glycosylation profile of PrPres and on the conformational stability of PrPSc. 
In this study a new conformational stability assay was developed based on the differential solubility of PrPC and PrPSc: CSSA (conformational stability and solubility assay). The conformational stability assay was performed by measuring PrPSc solubility in homogenates treated with increasing concentrations of GdnHCl, in the absence of proteinase K. Indeed, dose-response curves allowed estimation of the concentration of GdnHCl able to solubilise 50% of PrPSc. The results showed that this method is valuable for the biochemical typing of strains in bank voles and it is also a promising tool for molecular analysis of natural prion isolates. 
CSSA also revealed strain-specific PrPSc conformational stabilities of ovine natural isolates so that this feature, combined with the N-terminal PrPSc cleavage, allowed differentiation of classical scrapie, including CH1641-like, from natural goat BSE and experimental sheep BSE.
In view of the implications concerning strain similarity between animal and human TSEs, the physico-chemical properties of the Nor98 with two human prion diseases (VPSPr and GSS) were compared in order to investigate the extent of the similarity between animal and human prion strains. The results showed an unexpected heterogeneity of the molecular features among human and sheep TSEs associated with internal PrPres fragments with the possible exception of Nor98 and a case of  GSS P102L. These similarities and differences need further investigation by N- and C-terminal sequencing and biological characterization.

In particular, we show that chaotic random variables enjoy the following form of universality: (a) the normal and chi-square approximations of any homogenous sum can be completely characterized and assessed by first switching to its Wiener chaos counterpart, and (b) the simple upper bounds and convergence criteria available on the Wiener chaos extend almost verbatim to the class of homogeneous sums.

description: Ultra-hot Jupiters are gas giants that orbit so close to their host star that they are tidally locked, causing a permanent hot dayside and a cooler nightside. Signatures of their nonuniform atmospheres can be observed with high-resolution transit transmission spectroscopy by resolving time-dependent velocity shifts as the planet rotates and varying areas of the evening and morning terminator are probed. These asymmetric shifts were seen for the first time in iron absorption in WASP-76b. Here, we search for other atoms/ions in the planet's transmission spectrum and study the asymmetries in their signals. We detect Li I, Na I, Mg I, Ca II, V I, Cr I, Mn I, Fe I, Ni I, and Sr II, and tentatively detect H I, K I, and Co I, of which V, Cr, Ni, Sr II, and Co have not been reported before. We notably do not detect Ti or Al, even though these species should be readily observable, and hypothesize this could be due to condensation or cold trapping. We find that the observed signal asymmetries in the detected species can be explained in different ways. We find a relation between the expected condensation or ionization temperatures and the strength of the observed asymmetry, which could indicate rain-out or recombination on the nightside. However, we also find a dependence on the signal broadening, which could imply a two-zoned atmospheric model, in which the lower atmosphere is dominated by a day-to-night wind, while the upper atmosphere is dominated by a vertical wind or outflow. These observations provide a new level of modeling constraint and will aid our understanding of atmospheric dynamics in highly irradiated planets.

Immunological responses to oxidized ferredoxin and its chemically modified derivatives
Creators: name: Gregerson, Dale
Publisher: name: University of British Columbia
Year: 2010

description: Guinea pig lymph node and spleen cells responded in vitro to con-canavalin A (con A), lipopolysaccharide (LPS), and a specific antigen, oxidized ferredoxin, in serum free medium, medium with mercaptoethanol (ME), medium with foetal calf serum (FCS), and medium with both FCS and ME. The addition of ME to serum free medium supported a mixed leucocyte reaction as did media with FCS or FCS and ME. Nylon wool fractionation of the cells eliminated the LPS response and treatment with anti-immunoglobulin (alg) and complement (C) reduced the LPS response indicating that LPS may be a B lymphocyte mitogen. The con A response was enhanced by the alg and Cl treatment. The specificities of the humoral and cellular immune responses to the amino terminal heptapeptide antigenic determinant of performic acid oxidized ferredoxin (O-Fd) were tested and compared using several synthetic peptides and analogues of the determinant in leucocyte migration inhibition tests with guinea pig spleen cells and inhibition of complement fixation between O-Fd and homologous rabbit antiserum. A tetrapeptide comprising the four amino acids at the carboxy terminal of the test determinant was able to produce significant inhibition of leucocyte migration. Modifications of amino acids within the tetrapeptide resulted in a loss of migration inhibition. This same peptide would only inhibit the complement fixation reaction if a hydrophobic group was attached to it. Otherwise a hexapeptide was required to produce significant inhibition of' complement fixation. Guinea pigs sensitized with a conjugate of the heptapeptide determinant and bovine serum albumin gave positive immediate and delayed skin reactions to conjugates of the heptapeptide with other proteins indicating that the heptapeptide functions as both a hapten and carrier. Also, migration of spleen cells from these animals was inhibited by O-Fd. The abilities of several chemically modified forms of ferredoxin to stimulate DNA synthesis in vitro in spleen cells from mice sensitized to O-Fd and to fix complement (C') in the presence of rabbit anti-O-Fd sera were tested. Of all the ,ferredoxins, only O-Fd, native ferredoxin (native-Fd) and N-ethylmaleimide alkylated ferredoxin (NEM-vFd) were able to stimulate DNA synthesis. O-Fd, native-Fd, acid precipitated ferredoxin (TCA-Fd) and dinitrophenylated O-Fd (DNP-O-Fd) fixed C' while methylated ferredoxin (meth-O-Fd) did not. NEM-Fd and carboxymethylated ferredoxin (CM-Fd) fixed C' weakly. Only native-Fd, O-Fd and NEM-Fd were found to be immunogenic in mice when assayed for lymphocyte stimulation by all of the ferredoxins., The 24 hour DNA synthetic response was sensitive to treatment with anti-mouse immunoglobulin and C' and anti-brain associated 0 and C1 while the 120 hour response was only sensitive to the'anti-O and C'.

description: We compute 2-loop QCD corrections to the hard coefficient functions which arise in the factorization formula for B -> X_u l nu decays in the shape-function region. Our calculation provides the last missing piece required for a NNLO analysis of inclusive semileptonic B decays, which may significantly reduce the theoretical uncertainty in the extraction of the CKM matrix element |V_ub|. Among the technical aspects, we find that the 2-loop hard coefficient functions are free of infrared singularities as predicted by the factorization framework. We perform a brief numerical analysis of the NNLO corrections and include a discussion on charm mass effects.

description: Precise temporal coordination of gene expression is crucial for many developmental processes. One central question in developmental biology is how such coordinated expression patterns are robustly controlled. During embryonic development of the Drosophila central nervous system, neural stem cells called neuroblasts sequentially express a group of genes in a definite order, which generates the diversity of cell types. By producing all possible regulatory networks of these genes and examining their expression dynamics numerically, we identify requisite regulations and predict an unknown factor to reproduce known expression profiles caused by loss-of-function or overexpression of the genes in vivo, as well as in the wild type. We then evaluate the stability of the actual Drosophila network for sequential expression. This network shows the highest robustness against parameter variations and gene expression fluctuations among the possible networks that reproduce the expression profiles. We propose a regulatory module composed of three kinds of regulations which is responsible for precise sequential expression. The present study suggests an underlying principle on how biological systems are robustly designed under functional constraint.

description: We argue that if color-superconducting quark matter exists in the core of a neutron star, it may contain a high density of flux tubes, carrying flux that is mostly color-magnetic, with a small admixture of ordinary magnetic flux. We focus on the two-flavor color-superconducting ("2SC") phase, and assume that the flux tubes are energetically stable, although this has not yet been demonstrated. The density of flux tubes depends on the nature of the transition to the color-superconducting phase, and could be within an order of magnitude of the density of magnetic flux tubes that would be found if the core were superconducting nuclear matter. We calculate the cross-section for Aharonov-Bohm scattering of gapless fermions off the flux tubes, and the associated collision time and frictional force on a moving flux tube. We discuss the other forces on the flux tube, and find that if we take in to account only the forces that arise within the 2SC core region then the timescale for expulsion of the color flux tubes from the 2SC core is of order 10^10 years.

description: We prove that the L^2 Riemannian metric on the manifold of all smooth Riemannian metrics on a fixed closed, finite-dimensional manifold induces a metric space structure. As the L^2 metric is a weak Riemannian metric, this fact does not follow from general results. In addition, we prove several results on the exponential mapping and distance function of a weak Riemannian metric on a Hilbert/Frechet manifold. The statements are analogous to, but weaker than, what is known in the case of a Riemannian metric on a finite-dimensional manifold or a strong Riemannian metric on a Hilbert manifold.

description: Fragment properties of hot fragmenting sources of similar sizes produced in central and semi-peripheral collisions are compared in the excitation energy range 5-10 AMeV. For semi-peripheral collisions a method for selecting compact quasi-projectiles sources in velocity space similar to those of fused systems (central collisions) is proposed. The two major results are related to collective energy. The weak radial collective energy observed for quasi-projectile sources is shown to originate from thermal pressure only. The larger fragment multiplicity observed for fused systems and their more symmetric fragmentation are related to the extra radial collective energy due to expansion following a compression phase during central collisions. A first attempt to locate where the different sources break in the phase diagram is proposed.

Spin-orbit-entangled nature of magnetic moments and Kitaev magnetism in layered halides $α$-RuX$_3$ (X = Cl, Br, I)

description: $α$-RuCl$_3$ has been extensively studied recently because of potential bond-dependent Kitaev magnetic exchange interactions and the resulting quantum spin liquid phase that can be realized therein. It has been known that the covalency between Ru 4$d$- and Cl $p$-orbitals is crucial to induce large Kitaev interactions in this compound, therefore replacing Cl into heavier halogen elements such as Br or I can be a promising way to promote the Kitaev interaction even further. In a timely manner, there have been reports on synthesis of $α$-RuBr$_3$ and $α$-RuI$_3$, which are expected to host the same spin-orbit-entangled orbitals and Kitaev exchange interactions with $α$-RuCl$_3$. Here in this work we investigate electronic structures of $α$-RuCl$_3$, $α$-RuBr$_3$, and $α$-RuI$_3$ in a comparative fashion, focusing on the cooperation of the spin-orbit coupling and on-site Coulomb repulsions to realize the spin-orbit-entangled pseudospin-1/2 at Ru sites. We further estimate magnetic exchange interactions of all three compounds, showing that $α$-RuBr$_3$ can be promising candidates to realize Kitaev spin liquid phases in solid-state systems.

description: We present a three dimensional hot Jupiter model, extending from 200 bar to 1 mbar, using the Intermediate General Circulation Model from the University of Reading. Our horizontal spectral resolution is T31 (equivalent to a grid of 48x96), with 33 logarithmically spaced vertical levels. A simplified (Newtonian) scheme is employed for the radiative forcing. We adopt a physical set up nearly identical to the model of HD 209458b by Cooper & Showman (2005,2006) to facilitate a direct model inter-comparison. Our results are broadly consistent with theirs but significant differences also emerge. The atmospheric flow is characterized by a super-rotating equatorial jet, transonic wind speeds, and eastward advection of heat away from the dayside. We identify a dynamically-induced temperature inversion ("stratosphere") on the planetary dayside and find that temperatures at the planetary limb differ systematically from local radiative equilibrium values, a potential source of bias for transit spectroscopic interpretations. While our model atmosphere is quasi-identical to that of Cooper & Showman (2005,2006) and we solve the same meteorological equations, we use different algorithmic methods, spectral-implicit vs. grid-explicit, which are known to yield fully consistent results in the Earth modeling context. The model discrepancies identified here indicate that one or both numerical methods do not faithfully capture all of the atmospheric dynamics at work in the hot Jupiter context. We highlight the emergence of a shock-like feature in our model, much like that reported recently by Showman et al. (2009), and suggest that improved representations of energy conservation may be needed in hot Jupiter atmospheric models, as emphasized by Goodman (2009).

Common envelopes in massive stars: Towards the role of radiation pressure and recombination energy in ejecting red supergiant envelopes

description: We perform 3D hydrodynamical simulations of a common-envelope event involving a 12 solar mass red supergiant donor. Massive stars are expected to be qualitatively different from low-mass stars as their envelopes have significant support from radiation pressure, which increases both the final separation and amount of mass ejected through the common-envelope interaction. We perform adiabatic simulations that include radiation energy through the equation of state, which results in ejecting 60 per cent more mass (up to two thirds of the total envelope mass becoming unbound, or more) and yield a 10 per cent larger final separation compared to simulations that assume an ideal gas. When also including recombination energy, we find that at least three quarters of the envelope, and possibly the entire envelope, may be unbound. The final separation further increases by almost 20 per cent. The additional amount of ejected material is mainly due to energy injected from helium recombination. Hydrogen recombination plays a comparatively small role, as it mainly occurs in gas that has already become unbound. We conclude that the internal energy of the envelope can be a significant energy source for ejecting the common envelope, but ultimately radiation transport and convection need to be included.
