description: We discuss the resummation approach in QCD Analytic Perturbation Theory (APT). We start with a simple example of asymptotic power series for a zero-dimensional analog of the scalar $g\,ϕ^4$ model. Then we give a short historic preamble of APT and show that renormgroup improvement of the QCD perturbation theory dictates to use the Fractional APT (FAPT). After that we discuss the (F)APT resummation of nonpower series and provide the one-, two-, and three-loop resummation recipes. We show the results of applications of these recipes to the estimation of the Adler function $D(Q^2)$ in the $N_f=4$ region of $Q^2$ and of the Higgs-boson-decay width $Γ_{H\to b\bar{b}}(m_H^2)$ for $M_H=100-180$ GeV$^2$.

description: We study the condition for a topological superconductor (TS) phase with end Majorana fermions to appear when a quasiperiodic lattice modulation is applied to a one-dimensional quantum wire with strong spin-orbit interaction situated under a magnetic field and in proximity to a superconductor. By density-matrix renormalization group analysis, we find that multiple topological phases with Majorana end modes are realized in finite ranges of the filling factor, showing a sequence of reentrant transitions as the chemical potential is tuned. The locations of these phases reflect the structure of bands in the non-interacting case, which exhibits a distinct self-similar structure. The stability of the TS in the presence of an on-site interaction or a harmonic trap potential is also discussed.

description: When Offenbach’s La Vie parisienne premiered in Paris in 1866, it entered a longstanding debate on what it meant to be “Parisian.” This article uses La Vie parisienne to explore a key facet of Second Empire modernity: the notion that the Paris was a theater and that its dwellers were actors in a play. The operetta’s title alludes to a popular magazine likewise titled La Vie parisienne, which compared the rituals of Parisians to the scripted behaviors of theatrical characters. The librettists Meilhac and Halévy worked for the magazine in the early 1860s, and subsequently dedicated their operetta to the magazine’s founder, Marcelin. Three co-written vaudevilles reflect Marcelin’s attitudes about urban life and contain the prototypes of La Vie parisienne’s protagonists. As an example of what I call “cosmopolitan realism” in Second-Empire culture, the operetta assumed the function of an operatic anthology—analyzing, taxonomizing, and mythologizing Paris’s spaces, citizens and visitors. Long at the fringes of opera scholarship, operetta and vaudeville provide a rich corpus of literature that aestheticized the industrializing city, contributing to what Offenbach’s contemporaries, such as Charles Baudelaire and Gustave Claudin, diagnosed as la vie moderne.

description: Primary decomposition of commutative monoid congruences is insensitive to certain features of primary decomposition in commutative rings. These features are captured by the more refined theory of mesoprimary decomposition of congruences, introduced here complete with witnesses and associated prime objects. The combinatorial theory of mesoprimary decomposition lifts to arbitrary binomial ideals in monoid algebras. The resulting binomial mesoprimary decomposition is a new type of intersection decomposition for binomial ideals that enjoys computational efficiency and independence from ground field hypotheses. Binomial primary decompositions are easily recovered from mesoprimary decomposition.

description: HI gas collisions at 50-100 km/s driven by galactic tidal interactions between the Large and Small Magellanic Clouds (the LMC and SMC, respectively) are proposed to be a cluster formation process (Fukui+17; Tsuge+19). In N159, in the southeastern part of the LMC, oriented filamentary molecular clouds, which are oriented to the direction of HI collisions, were identified. This suggests that kpc-scale HI gas collisions have induced the formation of filamentary clouds with a width of 0.1 pc. In this study, we focus on N44, N11, and N79, where evidence for HI collisions has been found, and investigate the universality and variety of molecular cloud formation. The collision velocities of HI gas in N44, N11, and N79 are 70, 50, and 30 km/s, respectively, and the pressures of collisional compression are 14, 11, and 4 [10^5 K /cm^3], respectively. We found that there is a correlation between the pressure and the number of high-mass stars formed. Furthermore, filamentary molecular clouds were identified on the pc scale by the ALMA Cycle8 2021 molecular cloud survey (PI: K., Tsuge). The velocity dispersion, 13CO/12CO intensity ratio, mass, and filament aspect ratio were compared among the three regions, revealing that N44 had the highest values, followed by N11 and N79. The results show that N44 > N11 > N79 for all physical properties. These features suggest that more intense HI gas collisions possibly create a higher-pressure environment and promote the formation of more massive, denser, more filamentary, and more complex velocity structures, leading to the efficient formation of high-mass stars. Furthermore, we note that high-velocity gas collisions impact both atomic/molecular gases and drive plasma evolution. Knies+21 proposed a 3D structure of gas collisions toward 30 Dor by using diffuse X-ray absorption and suggested its role in heating diffuse hot gas emitting X-rays. A comparison of the diffuse X-ray properties with HI/CO gas in the LMC, including N44 and N11 regions, is underway using eROSITA (Tsuge+24 submitted). I also plan to discuss the future ALMA observations and synergies with next-generation X-ray missions (Athena, XRISM) to investigate ISM evolution birth of stars to its endpoint.

description: No abstracts are to be cited without prior reference to the author.Henslow’s swimming crab (Polybius henslowi) is a crustacean species with pelagic and demersal habits distributed from north African to Biscay Gulf (González-Gurriarán, 1978). It occurs in high densities in located patches along the continental shelf and upper slope of north western Spanish continental shelf and upper slope where it is discarded in large numbers by Spanish trawl fisheries at the area due to the lack of commercial value. Discarding estimates reach up 20% of total discarded weight and around 40% of number of fish and crustaceans of overall trawl catches in the area. More than 300 kg per fishing trip were discarded in 2007.

description: The hydrodynamic model including the spin degree of freedom and the electromagnetic field was discussed. In this derivation, we applied electromagnetism for macroscopic medium proposed by Minkowski. For the equation of motion of spin, we assumed that the hydrodynamic representation of the Pauli equation is reproduced when the many-body effect is neglected. Then the spin-magnetic interaction in the Pauli equation was converted to a part of the magnetization. The fluid and spin stress tensors induced by the many-body effect were obtained by employing the algebraic positivity of the entropy production in the framework of the linear irreversible thermodynamics, including the mixing effect of the irreversible currents. We further constructed the constitutive equation of the polarization and the magnetization. Our polarization equation is more reasonable compared to another result obtained using electromagnetism for macroscopic medium proposed by de Groot-Mazur.

Lett. 106, 180504 (2011) which provides a method for benchmarking quantum gates and estimating the gate-dependence of the noise. The protocol allows the noise to have weak time and gate-dependence, and we provide a sufficient condition for the applicability of the protocol in terms of the average variation of the noise. We discuss how state preparation and measurement errors are taken into account and provide a complete proof of the scalability of the protocol. We establish a connection in special cases between the error rate provided by this protocol and the error strength measured using the diamond norm distance.

description: Ice shelves control sea-level rise through frictional resistance, which slows the seaward flow of grounded glacial ice. Evidence from around Antarctica indicates that ice shelves are thinning and weakening, primarily driven by warm ocean water entering into the shelf cavities. We have identified a mechanism for ice shelf destabilization where basal channels underneath the shelves cause ice thinning that drives fracture perpendicular to flow. These channels also result in ice surface deformation, which diverts supraglacial rivers into the transverse fractures. We report direct evidence that a major 2016 calving event at Nansen Ice Shelf in the Ross Sea was the result of fracture driven by such channelized thinning and demonstrate that similar basal channel–driven transverse fractures occur elsewhere in Greenland and Antarctica. In the event of increased basal and surface melt resulting from rising ocean and air temperatures, ice shelves will become increasingly vulnerable to these tandem effects of basal channel destabilization.

description: Mitigating climate change by reducing greenhouse gas emissions has many health co-benefits and is a top public health priority. Policies to limit emissions are associated with improvements across a wide range of public health outcomes, including, among other impacts, obesity, acute respiratory infections among children, and ischaemic heart disease in adults [1]. However, recognition that climate change is already underway has led to an increasing focus on adaptation. Studies projecting the impacts of future climate change on health date back to the late 1980s, and their number has grown substantially in recent years. Climate change impact assessments generally use the output of global climate models (GCMs). Here, we profile, and suggest means for addressing, the challenges associated with the use of GCM projections for impact studies to inform adaptation. GCMs provide projections of the climate at a typical resolution of about 100 km2. Such low precision is of limited use to decision-makers trying to determine how climate change might affect their particular district, town, or even country. Often, a regional climate model is employed to ‘downscale’ the output of the global model to a resolution considered more useful for practical applications. Climate model output can then be used to drive disease models or to investigate the risks of surpassing health-relevant climate thresholds in the future.

description: Since 2014, Danish composer Louise Alenius has engaged in a series of performances characterized by extraordinary circumstances entitled Porøset. Eminently site-specific, Porøset has been mounted within the disheveled attic spaces and compact dressing rooms of the Royal Danish Theater in Copenhagen. Alenius, the sole recurring participant in each performance, meticulously structures these performances utilizing three striking parameters. Each performance (exhibiting different combinations of singing, dancing, acting, and speaking) lasts just fifteen minutes, and is staged within a location of the Royal Danish Theater disclosed to the audience member only just prior to the performance’s commencement. Most crucially, each performance is presented for a single audience member at a time, a setting provoking intense intimacy and vulnerability between its audience member and performers. With information obtained through interviews with Alenius herself, I engage Porøset with phenomenological models formulated by Emmanuel Levinas and Maurice Merleau-Ponty to assess and illuminate the intersubjectivity that emerges between the performers and audience member within these esoteric encounters. By conducting such an investigation, I strive to accentuate the experiential significance of this contemporary composer’s oeuvre, one boldly traversing the boundaries between music, theater, and performance art to achieve a timely holistic aspiration: the delicate formation of trust between strangers.

description: A fraction of the extragalactic near-infrared (near-IR) background light involves redshifted photons from the ultraviolet (UV) emission from galaxies present during reionization at redshifts above 6. The absolute intensity and the anisotropies of the near-IR background provide an observational probe of the first-light galaxies and their spatial distribution. We estimate the extragalactic background light intensity during reionization by accounting for the stellar and nebular emission from first-light galaxies. We require the UV photon density from these galaxies to generate a reionization history that is consistent with the optical depth to electron scattering from cosmic microwave background measurements. We also require the bright-end luminosity function of galaxies in our models to reproduce the measured Lyman drop-out luminosity functions at redshifts of 6 to 8. The absolute intensity is about 0.1 to 0.3 nW m$^{-2}$ sr$^{-1}$ at the peak of its spectrum at $\sim$ 1.1 $μ$m. We also discuss the anisotropy power spectrum of the near-IR background using a halo model to describe the galaxy distribution. We compare our predictions for the anisotropy power spectrum to existing measurements from deep near-IR imaging data from {\it Spitzer}/IRAC, {\it Hubble}/NICMOS, and {\it AKARI}. The predicted rms fluctuations at tens of arcminute angular scales are roughly an order of magnitude smaller than the existing measurements. While strong arguments have been made that the measured fluctuations do not have an origin involving faint low-redshift galaxies, we find that the existing measurements are also incompatible with an origin during the era of reionization. The measured near-IR background anisotropies remain unexplained and could be associated with an unidentified non-astrophysical origin.

description: Using an empirical pseudopotential description of electron states and an adiabatic bond charge model for phonon states in bulk silicon, we theoretically investigate two-photon indirect optical injection of carriers and spins and two-color coherent control of the motion of the injected carriers and spins. For two-photon indirect carrier and spin injection, we identify the selection rules of band edge transitions, the injection in each conduction band valley, and the injection from each phonon branch at 4 K and 300 K. At 4 K, the TA phonon-assisted transitions dominate the injection at low photon energies, and the TO phonon-assisted at high photon energies. At 300 K, the former dominates at all photon energies of interest. The carrier injection shows anisotropy and linear-circular dichroism with respect to light propagation direction. For light propagating along the $<001>$ direction, the carrier injection exhibits valley anisotropy, and the injection into the $Z$ conduction band valley is larger than that into the $X/Y$ valleys. For $σ^-$ light propagating along the $<001>$ ($<111>$) direction, the degree of spin polarization gives a maximum value about 20% (6%) at 4 K and -10% (20%) at 300 K, and at both temperature shows abundant structure near the injection edges due to contributions from different phonon branches. Forthe two-color coherent current injection with an incident optical field composed of a fundamental frequency and its second harmonic, the response tensors of the electron (hole) charge and spin currents are calculated at 4 K and 300 K. We show the current control for three different polarization scenarios. The spectral dependence of the maximum swarm velocity shows that the direction of charge current reverses under increase in photon energy.

description: Bioacoustic networks could vastly expand the coverage of wildlife monitoring to complement satellite observations of climate and vegetation. This approach would enable global-scale understanding of how climate change influences phenomena such as migratory timing of avian species. The enormous data sets that autonomous recorders typically generate demand automated analyses that remain largely undeveloped. We devised automated signal processing and machine learning approaches to estimate dates on which songbird communities arrived at arctic breeding grounds. Acoustically estimated dates agreed well with those determined via traditional surveys and were strongly related to the landscape’s snow-free dates. We found that environmental conditions heavily influenced daily variation in songbird vocal activity, especially before egg laying. Our novel approaches demonstrate that variation in avian migratory arrival can be detected autonomously. Large-scale deployment of this innovation in wildlife monitoring would enable the coverage necessary to assess and forecast changes in bird migration in the face of climate change.

description: No abstracts are to be cited without prior reference to the author.Fishing Discards have long been recognized as a harmful practice for fisheries, therefore, accurate and unbiased quantifications are of major concern to fisheries assessment purposes. Discard estimations in Spanish fisheries are based on stratified random sampling of trips (primary sampling unit) per metier and year, following the general ICES raising procedures (ICES, 2003). This sampling scheme yields analytical estimations of mean and variance with their bias and precision depending on several issues such as: i) Method for selecting samples ii) Variability in the data iii) Estimator used The high error values associated with discards sampling programs imply some levels of bias when analytical quantification is carried out . The main aim of this preliminary study is to apply bootstrap methods in order to provide robust estimations of discards. Further, we use the bootstrap to evaluate the errors associated with ordinary estimations and to explore the consequences in bias and precision under different simulated sampling scenarios. This methodology is applied here on megrim (Lepidorhombus whiffiagonis) discard data, which was recorded for the Spanish discard monitoring progam by observers on board the bottom trawl fleet operating in ICES Subareas VI-VII

description: The six lead miniature temples found in the cargo of the shipwreck of Valle Ponti, located at Comacchio (province of Ferrara, Italy) and dated to the last quarter of the first century BC, have often been interpreted as a unicum in the Roman world. The main objective of the study is the contextualization of this category of objects within the cult in the seas, which is still waiting to be addressed in a complete and exhaustive way. Through the written sources and the iconographic and archaeological comparisons with similar artifacts and votive statuettes representing the same deities present in the ship of Valle Ponti new interpretative perspectives have been opened on the reasons behind the production of the lead temples, their use and the scope for which they may have been produced. Some symbolic elements and the deities represented seem to provide important clues about the ritual and religiosity on the wreck. In this perspective, the maritime-related cult in the classical world has been deepened, in an attempt to understand the meaning, the function and the position of the small temples inside the ship of Valle Ponti, by confronting the ancient primary sources with other worship-related objects found in mediterranean shipwrecks.

Evolutionarily conserved synthetic lethal interaction networks reveal targets for anticancer therapeutic development
Creators: name: Van Pel, Derek Michael
Publisher: name: University of British Columbia

description: Cancer is a multigenic disease. The genetic distinctness of cancer cells offers a weakness that can be exploited: for example, nearly all cancers carry mutations in processes relating to the maintenance of genomic stability. As this is an essential process, this presents a weakness that can be leveraged towards inviability – a concept known as synthetic lethality. The ideal cancer therapeutic would have a broad spectrum, but genetic techniques in human cells are not sufficiently developed to identify the spectrum of synthetic lethal interactions of sets of genome stability genes easily. The use of model organisms can facilitate the identification of second-site targets for the development of anticancer therapeutics, and allows the construction of synthetic lethal interaction networks. This has the potential to identify “hub” genes having synthetic lethal interactions with many cancermutated orthologs. If these synthetic lethal interactions are found to be conserved in human cells, these highly connected hub genes are potential targets for therapeutic development. Assembly of a synthetic lethal interaction network of yeast orthologs of 10 genes mutated in colorectal cancer, based on data in Saccharomyces cerevisiae, previously identified five such synthetic lethal hub genes in yeast. In this thesis, the evolutionary conservation of this network is interrogated in mammalian cells. The interactions between orthologs of colorectal cancer CIN genes in yeast were found to be highly conserved in human cells. A highthroughput assay to screen for small-molecule inhibitors of the protein encoded by one such gene, FEN1, was developed and used to identify 13 compounds that inhibited FEN1 in vitro with IC50 values in the low-micromolar range or less. These compounds were applied to cells bearing mutation in the tumor suppressor CDC4, and two compounds were found to yield selective killing of CDC4-deficient cells. Finally, yeast genetic techniques were used to characterize CTF4, a second highly connected hub gene within the colon cancer CIN gene network, and to expand the therapeutic range of cancers that could be selectively killed by inhibitors of Ctf4/WDHD1 or Rad27/FEN1. Taken together, these data demonstrate the considerable power of applying model organisms genetics to the discovery of new anticancer therapeutic targets.

description: This paper presents a microanalytical characterization of amphora samples from the Roman villa site in Bocca delle Menate, Comacchio (FE), located in the Northern Adriatic area. Previous archaeological studies indicate that the majority of transport containers date back to the first half of the first century BCE and the first half of the third century AD. In this study, a total of 58 amphora samples were analyzed using a combination of Munsell chart and stereomicroscopic techniques to describe the clays and tempers. The objective was to categorize the amphora sherds into fabric groups. A smaller subset of samples was further analyzed using the non-destructive analytical technique of SEM-EDS to provide a semi-quantitative chemical characterization of the major elements in the fabric. It should be noted that the results of this research are preliminary and further analyses are recommended to determine a more accurate provenance of the amphorae.

description: We show how to compute the probabilities of various connection topologies for uniformly random spanning trees on graphs embedded in surfaces. As an application, we show how to compute the "intensity" of the loop-erased random walk in ${\mathbb Z}^2$, that is, the probability that the walk from (0,0) to infinity passes through a given vertex or edge. For example, the probability that it passes through (1,0) is 5/16; this confirms a conjecture from 1994 about the stationary sandpile density on ${\mathbb Z}^2$. We do the analogous computation for the triangular lattice, honeycomb lattice and ${\mathbb Z} \times {\mathbb R}$, for which the probabilities are 5/18, 13/36, and $1/4-1/π^2$ respectively.
description: 45 pages, many figures. v2 has an expanded introduction, a revised section on the LERW intensity, and an expanded appendix on the annular matrix

description: As opposed to other realms of art, like literature or painting, a plethora of “great women singers” has existed in the Caribbean and Latin America since the recording industry began. These were marquee artists with legions of adoring fans. Yet, the critical paucity regarding their careers has been severe. It seems obvious, but bears repeating, that, at the beginning of the twenty-first century, most music writing on Latin America did not engage in a hermeneutic with regards to gender. As I compiled buried, fragmentary, or discarded archival objects, I came to think of my subjects as not having come into critical view yet, as not yet being “interpretable.” I found in the nothing a highly suggestive concept that allowed me to work productively with absences and omissions, but also to analyze singers as able sculptors of a generative nothingness. Related to both the nothing as empty and, in contradistinction, as empty-set, a paradoxical “full emptiness,” I had to consider the common-sense concept of diva, often employed to account for every instance of female stardom and success (rendering it empty). For this book, I decided to keep my critical stance at a remove from the “diva” while not discounting the term’s everyday and scholarly use, the moments when it indexes the generative nothing (which might be one of its definitions). In The Great Woman Singer, I opted for a deferral of diva in favor of a foregrounding of musician.

description: Extreme temperatures are one of the leading causes of death and disease in both developed and developing countries, and heat extremes are projected to rise in many regions. To reduce risk, heatwave plans and cold weather plans have been effectively implemented around the world. However, much of the world's population is not yet protected by such systems, including many data-scarce but also highly vulnerable regions. In this study, we assess at a global level where such systems have the potential to be effective at reducing risk from temperature extremes, characterizing (1) long-term average occurrence of heatwaves and coldwaves, (2) seasonality of these extremes, and (3) short-term predictability of these extreme events three to ten days in advance. Using both the NOAA and ECMWF weather forecast models, we develop global maps indicating a first approximation of the locations that are likely to benefit from the development of seasonal preparedness plans and/or short-term early warning systems for extreme temperature. The extratropics generally show both short-term skill as well as strong seasonality; in the tropics, most locations do also demonstrate one or both. In fact, almost 5 billion people live in regions that have seasonality and predictability of heatwaves and/or coldwaves. Climate adaptation investments in these regions can take advantage of seasonality and predictability to reduce risks to vulnerable populations.
Intercultural Circulation and Short Circuits in the Society of Jesus between Italy, Japan, and China (17th–18th centuries)

description: This essay compares different channels of cultural dissemination regarding the Jesuit missions as found within the applications for the overseas territories (litterae indipetae) sent by Italians at the turn of the eighteenth century[1]. Jesuits regularly read letters and treatises (by Francis Xavier and Daniello Bartoli, among others), and their importance is confirmed by applications for the missions in which the Jesuits relate their vocation to these sources. The Histories of the Society of Jesus written by Daniello Bartoli in the 17th century, for instance, remained inspirational among members of the religious order at least two hundred years. However, for these Jesuits, the lack of updated and objective information could lead to curious misunderstandings, like the “fake news” spread through Southern Italian colleges that Japan was reopening to foreigners and Christianity.

description: The drag and diffusion coefficients of a hot hadronic medium consisting of pions, kaons and eta using open beauty mesons as a probe have been evaluated. The interaction of the probe with the hadronic matter has been treated in the framework of chiral perturbation theory. It is observed that the magnitude of both the transport coefficients are significant, indicating substantial amount of interaction of the heavy mesons with the thermal bath. The results may have significant impact on the experimental observables like the suppression of single electron spectra originating from the decays of heavy mesons produced in nuclear collisions at RHIC and LHC energies

description: Given that my own work is focused on questions of diaspora, visuality, and queerness, I am very grateful for the fact that Fiol-Matta models for us a mode of both listening and looking with deep care. This critical listening and critical looking make apparent an entirely different understanding of Puerto Rican music culture, through an examination of how women singers have negotiated the impossible demands placed on their star bodies. Fiol-Matta theorizes for us the intimate relation between the visual and the aural. As such, her work in fact powerfully resonates with that of visual studies scholars such as Tina Campt, Christopher Pinney, and Krista Thompson.
Forward modeling of thermally activated single-domain magnetic particles applied to First Order Reversal Curves

description: Theoretical first-order reversal curves (FORCs) were generated by numerically solving a thermally activated Stoner-Wohlfarth model for assemblages of randomly oriented magnetic particles. The thermally activated Stoner-Wohlfarth model extends previous models based on Preisach theory. The new numerical simulations show that the shapes of reversal curves and the FORC distributions are significantly modified by the effect of the thermal energy only if superparamagnetic particles are predominant. However, most assemblages containing moderate amounts of superparamagnetic particles are hardly distinguishable from stable single-domain assemblages. The most relevant thermal effect is a reduction of coercivity that translates in a shift of the FORC distribution toward the origin. Not all of the distinctive characteristics previously predicted for superparamagnetic grain assemblages were confirmed by our calculations, and most of the observed modifications due to thermal effects can be considered minor. A direct comparison with hysteresis parameters shows that these simpler experiments can be equally effective in characterizing viscous and superparamagnetic particles.
Flavor Symmetry and Topology Change in Nuclear Symmetry Energy for Compact Stars

description: The nuclear symmetry energy figures crucially in the structure of asymmetric nuclei and, more importantly, in the equation of state (EoS) of compact stars. At present it is almost totally unknown, both experimentally and theoretically, in the density regime appropriate for the interior of neutron stars. Basing on a strong-coupled structure of dense baryonic matter encoded in the skyrmion crystal approach with a topology change and resorting to the notion of generalized HLS (hidden local symmetry) in hadronic interactions, we address a variety of hitherto unexplored issues of nuclear interactions associated with the symmetry energy, i.e., kaon condensation and hyperons, possible topology change in dense matter, nuclear tensor forces, conformal symmetry and chiral symmetry etc in the EoS of dense compact-star matter. One of the surprising results coming from the hidden local symmetry structure that is distinct from what is given by standard phenomenological approaches is that at high density, baryonic matter is driven by RG flow to the "dilaton-limit fixed point (DLFP)" constrained by "mended symmetries." We further propose how to formulate kaon condensation and hyperons in compact-star matter in a framework anchored on a single effective Lagrangian by treating hyperons as the Callan-Klebanov kaon-skyrmion bound states simulated on crystal lattice. This formulation suggests that hyperons can figure in the stellar matter -- if at all -- when or after kaons condense, in contrast to the standard phenomenological approaches where the hyperons appear as the first strangeness degree of freedom in matter thereby suppressing or delaying kaon condensation. In our simplified description of the stellar structure in terms of symmetry energies which is compatible with that of the 1.97 solar mass star, kaon condensation plays a role of "doorway state" to strange-quark matter.
