description: Fermionic theories with a vanishing chiral condensate (in the chiral limit) have recently attracted considerable interest; in particular variants of multi-flavour QCD are candidates for this behaviour. Here we consider the 2-flavour Schwinger model as a simple theory with this property. Based on simulations with light dynamical overlap fermions, we test the hypothesis that in such models the low lying Dirac eigenvalues could be decorrelated. That has been observed in 4d Yang-Mills theories at high temperature, but it cannot be confirmed for the 2-flavour Schwinger model. We also discuss subtleties in the evaluation of the mass anomalous dimension and its IR extrapolation.

description: Low-loss superconducting rf devices are required when used for quantum computation. Here, we present a series of measurements and simulations showing that conducting losses in the packaging of our superconducting resonator devices affect the maximum achievable internal quality factors (Qi) for a series of thin-film Al quarter-wave resonators with fundamental resonant frequencies varying between 4.9 and 5.8 GHz. By utilizing resonators with different widths and gaps, different volumes of the stored electromagnetic energy were sampled thus affecting Qi. When the backside of the sapphire substrate of the resonator device is adhered to a Cu package with a conducting silver glue, a monotonic decrease in the maximum achievable Qi is found as the electromagnetic sampling volume is increased. This is a result of induced currents in large surface resistance regions and dissipation underneath the substrate. By placing a hole underneath the substrate and using superconducting material for the package, we decrease the ohmic losses and increase the maximum Qi for the larger size resonators.

description: We perform realistic shell-model calculations for nuclei with valence nucleons outside 48Ca, employing two different model spaces. The matrix elements of the effective two-body interaction and electromagnetic multipole operators have been calculated within the framework of the many-body perturbation theory, starting from a low-momentum potential derived from the high-precision CD-Bonn free nucleon-nucleon potential. The role played by the neutron orbital 1d5/2 has been investigated by comparing experimental data on yrast quadrupole excitations of isotopic chains north-east of 48Ca with the results of calculations including or not including this single-particle state in the model space.

For this purpose the velocity dependent potential gives rise to a generalized Gauss kernel. Besides the propagators also the generating functionals are obtained.

description: Anomaly detection, an important branch of machine learning, plays a critical role in fraud detection, health care, intrusion detection, military surveillance, etc. As one of the most commonly used unsupervised anomaly detection algorithms, the Local Outlier Factor algorithm (LOF algorithm) has been extensively studied. This algorithm contains three steps, i.e., determining the k-distance neighborhood for each data point x, computing the local reachability density of x, and calculating the local outlier factor of x to judge whether x is abnormal. The LOF algorithm is computationally expensive when processing big data sets. Here we present a quantum LOF algorithm consisting of three parts corresponding to the classical algorithm. Specifically, the k-distance neighborhood of x is determined by amplitude estimation and minimum search; the local reachability density of each data point is calculated in parallel based on the quantum multiply-adder; the local outlier factor of each data point is obtained in parallel using amplitude estimation. It is shown that our quantum algorithm achieves exponential speedup on the dimension of the data points and polynomial speedup on the number of data points compared to its classical counterpart. This work demonstrates the advantage of quantum computing in unsupervised anomaly detection.

description: (Abridged) The role of low ionization nuclear emission region (LINER) galaxies within the picture of active galactic nuclei (AGN) has been controversial. It is still not clear whether they host an AGN in a low accretion mode, or whether they are not active at all but dominated by alternative ionization mechanisms, namely shocks, winds/outflows, or photoionization by a post asymptotic giant branch (p-AGB) stellar population. The detection of extended LINER-like emission was often taken as evidence of ionization by stellar components but this has not been undisputed. We performed optical integral field spectroscopic observations on the central approx. 4 kpc of NGC 5850 using VIMOS at the VLT, which provides spatially-resolved spectra for the gas emission and the stellar continuum. We derive and analyse emission line and kinematic maps. We find the central few kpc of NGC 5850 to be dominated by extended LINER-like emission. The emission-line ratios that are sensitive to the ionization parameter increase with radial distance to the nucleus. Therefore, the extended LINER-like emission in NGC 5850 is dominated by ionization from distributed ionization sources, probably by stars on the p-AGB. The LINER-like region is surrounded by emission that is classed as 'composite', likely due to a mixture of a LINER-like ionization pattern and photoionization by low-level star formation. Two star-forming regions are present in the 21"x19" field of view. One of them is located approximately in the ring surrounding the kinematically decoupled core. The second one is close to the nucleus and is the origin of a region of decreased emission line ratios oriented radially outwards. We find the interstellar gas to have areas of steep velocity gradients and a complex kinematic morphology, probably caused by the lopsided (m=1) distribution of the gas. The inflow of gas toward the center appears possible.

description: Although compensation is the governing principle in contract law remedies, it has tenuous historical, economic, and empirical support. A promisor's right to breach and pay damages is only a subset of a larger family of termination rights that do not purport to compensate the promisee for losses suffered when the promisor walks away from the contemplated exchange. These termination rights can be characterized as embedded options that serve important risk management functions. We show that sellers often sell insurance to their buyers in the form of these embedded call options, and that termination fees, including damages, are in essence option prices. Furthermore, we explain why compensation is of little relevance to the option price agreed to by the parties, which is a function of the option's value to the buyer, its cost to the seller, and the market in which they transact. We propose, therefore, a novel justification for why penalty liquidated damages may be higher than the seller's costs: They are option prices that reflect the value of the options to the buyer. The regulation of liquidated damages is thus tantamount to price regulation -- a function outside the realm of contract law. Moreover, in light of the generosity among optimal option prices, this Article also makes the case against the expectation damages default rule. In thick markets, we argue for enforcing the parties' risk allocation with market damages. In thin markets, we propose the default rule should encourage parties to agree explicitly to termination rights, including break damages, by the threat of specific performance of their contemplation exchange or, in the case of consumers, by a default rule that provides them a termination option at no cost.
title: Radiation Tolerant Acquisition System for Beam Loss Monitoring at High-Luminosity LHC
Creators: name: Martina, Francesco
Publisher: name: University of Liverpool Repository
Year: 2023

description: At CERN's Large Hadron Collider, the strategy for machine protection and the quench prevention of superconductive magnets heavily relies on the Beam Loss Monitoring system. For each turn of the beam train, a large amount of data is acquired from approximately 4000 detectors by 750 digital conversion cards. Within a strict deadline, the readout electronics compare the measured loss radiation with unique per detector thresholds, thus deciding whether the particle beams are permitted to continue circulating or trigger an interlock. In view of the accelerator High-Luminosity upgrade, this protection device needs to be improved in terms of resolution and response speed, enhancing its ability to detect potential hazardous scenarios promptly. Such targets require an entirely renewed electronic front-end that withstands a TID of at least 3 kGy and can be positioned as close as possible to the detection spots. Compared to the currently installed equipment, it will also provide a four times faster sampling rate of 100 kHz. Here, the research activities and the development of such upgrades are reported. They involve the engineering, implementation and validation of a real-time system that digitises the output current of the detectors, forwards the results to a non-radiation area and performs an optimised signal processing, in order to obtain precise and accurate beam loss current measurements. Amongst them, the support for the design and the characterisation of an application-specific integrated circuit is also included, which plays a crucial role in the analogue to digital conversion. A frequency domain analysis of the produced data stream is conducted, demonstrating the advantages of this approach over conventional methods. In this way, a detailed evaluation of the digitiser's behaviour has been carried out, in response to a wide range of inputs, and appropriate filtering techniques have been identified. Hence, the assembly of an overall system test-bench and the standardised measurement procedures have led to the validation of the readout firmware, the signal treatment chains and the system conversion performance. The devices successfully complied with the design specifications, including the input dynamic range of more than 160 dB and the tolerance to radiation. In addition, the novel processing has provided optimal measurement precisions or, complementary, fast step responses. Finally, the flexibility of the developed instruments allows them to be easily adapted beyond the original scope, such as for medical and technological applications or in other particle accelerators.
Market Damages, Efficient Contracting, and the Economic Waste Fallacy

description: Market damages are the best default rule when parties trade in thick markets: They induce parties to contract efficiently and to trade if and only if trade is efficient, and they do not create ex ante inefficiencies. Courts commonly overlook these virtues, however, when promisors bundle services that are not separately priced. For example, a promisor may agree to pay royalties on a mining  lease and later to restore the promisee's property. When the cost of completion is large relative to the "market delta" -- the increase in market value -- courts concerned with avoiding "economic waste" limit the buyer to the market value increase. This concern is misguided. Since the buyer commonly prepays for the service, a cost-of-completion award actually has a restitution element -- the prepaid price -- and an expectation interest element -- the market damages. Courts fail to see the restitution issue and thus deny these damages more frequently than they should. We argue first that the rule denying buyers market damages induces excessive entry into these service markets. Second, buyers are undercompensated when they prepay and cannot recover the price paid for the breached services. Finally, sellers often can take actions in the interim between making the contract and the time for performance of the service that would reduce the service cost to manageable proportions. Sellers are less likely to take these precautions if they are required to pay buyers only the market delta, rather than the full performance cost that their actions could have avoided.

description: Rapidly innovating industries are not behaving the way theory expects. Conventional industrial organization theory predicts that, when parties in a supply chain have to make transaction-specific investments, the risk of opportunism will drive them away from contracts and toward vertical integration. Despite the conventional theory, however, contemporary practice is moving in the other direction. Instead of vertical integration, we observe vertical disintegration in a significant number of industries, as producers recognize that they cannot themselves maintain cutting-edge technology in every field required for the success of their products. In doing this, the parties are developing forms of contracting beyond the reach of contract theory models. In this Article, we connect the emerging contract practice to theory, learning from what has happened in the real world to frame a theoretical explanation of this cross-organizational innovation and to reconceptualize the boundaries of the firm accordingly. We argue that the vertical disintegration of the supply chain in many industries is mediated neither by fully specified technical interfaces that allow suppliers to produce a modular piece of the ultimate product, nor by entirely implicit relational contracts supported only by norms of reciprocity and the expectation of future dealings. Rather, we suggest that the change in the boundary of the firm has given rise to a new form of contracting between firms -- what we call "contracting for innovation." This pattern braids explicit and implicit contracting to support iterative collaborative innovation by raising switching costs. These costs, represented by the parties' parallel transaction-specific investments in knowledge about their collaborators' capacities, deter opportunism under circumstances where explicit contracting, renegotiation, and the anticipation of future dealings cannot.
Exact solutions and superposition rules for Hamiltonian systems generalizing time-dependent SIS epidemic models with stochastic fluctuations

description: Using the theory of Lie-Hamilton systems, formal generalized time-dependent Hamiltonian systems that enlarge a recently proposed SIS epidemic model with a variable infection rate are considered. It is shown that, independently on the particular interpretation of the time-dependent coefficients, these systems generally admit an exact solution, up to the case of the maximal extension within the classification of Lie-Hamilton systems, for which a superposition rule is constructed. The method provides the algebraic frame to which any SIS epidemic model that preserves the above mentioned properties is subjected. In particular, we obtain exact solutions for generalized SIS Hamiltonian models based on the book and oscillator algebras, denoted by $\mathfrak{b}_2$ and $\mathfrak{h}_4$, respectively. The last generalization corresponds to a SIS system possessing the so-called two-photon algebra symmetry $\mathfrak{h}_6$, according to the embedding chain $\mathfrak{b}_2\subset \mathfrak{h}_4\subset \mathfrak{h}_6$, for which an exact solution cannot generally be found, but a nonlinear superposition rule is explicitly given.

title: La Caminata del Migrante as a Social Movement: The Framing and Making of the October 2018 Migrant Caravan
Creators: name: Rizzo Lara, Rosario de la Luz
Publisher: name: University of Kent
Year: 2023

description: In the fall of 2018, large groups of Central American undocumented migrants and asylum seekers arrived at the Mexico-Guatemala border to cross Mexico and arrive in the US. The first group left San Pedro Sula, Honduras on October 13, 2018. The group was called "La Caminata del Migrante." The event attracted attention from the local and international media, organizations, and civil society, given the size and composition of the group. This thesis aims to explore the formation and development of the October 2018 Migrant caravan from Honduras to the US, as previous migration movements from Central America have been characterized by individual or small-group clandestine migration. This thesis first proposes the use of social movements literature to analyze the features of the caravan and conceptualizes it as a transnational social movement on the move. Seeking to analyze its formation, the thesis also explores the different frames that were employed to mobilize participants and bystanders, as well as to gain public support for the caravan, and the resonance they had on participants to show which frames resonated the most and the least. Finally, looking to understand how the caravan developed and endured from San Pedro Sula (Honduras) to Tijuana (Mexico), I look at the collective identity caravan members created in transit and argue that it was fundamental to achieve, at least, some of its goals. Based on qualitative data collected during 2021-2022 using in-depth semi-structured interviews, informal talks, social media data, and the examination of secondary sources, I found that the caravan was planned and organized, as information about the movement circulated on social media weeks before its departure. Participants organized to meet at the bus station in San Pedro Sula (Honduras), and from there, they walked jointly to the US. The movement grew while in transit, partially in response to the frames that called participants to leave the country in groups by highlighting the advantages of migrating in a caravan. Social media enabled the emergence and enlargement of the movement, as images of migrants walking together were seen across the globe. The movement was horizontal and without a formal leader, having guides and coordinators setting the migratory route. The movement established two conflictual relationships at the local and international levels and used an innovative repertoire of contention. Participants constructed a collective identity in and through protest while the caravan was on the move and as they contested the racialized policies of exclusion states of the region had implemented.

description: Metamorphic testing is an advanced technique to test programs without a true test oracle such as machine learning applications. Because these programs have no general oracle to identify their correctness, traditional testing techniques such as unit testing may not be helpful for developers to detect potential bugs. This paper presents a novel system, Kabu, which can dynamically infer properties of methods' states in programs that describe the characteristics of a method before and after transforming its input. These Metamorphic Properties (MPs) are pivotal to detecting potential bugs in programs without test oracles, but most previous work relies solely on human effort to identify them and only considers MPs between input parameters and output result (return value) of a program or method. This paper also proposes a testing concept, Metamorphic Differential Testing (MDT). By detecting different sets of MPs between different versions for the same method, Kabu reports potential bugs for human review. We have performed a preliminary evaluation of Kabu by comparing the MPs detected by humans with the MPs detected by Kabu. Our preliminary results are promising: Kabu can find more MPs than human developers, and MDT is effective at detecting function changes in methods.
title: EXPLORING THE EXPERIENCE OF RESEARCH AND THE BUILDING OF RESEARCH CAPACITY AT A HIGHER EDUCATION INSTITUTION IN THE CARIBBEAN
Creators: name: Ferguson, Veronica
Publisher: name: University of Liverpool Repository
Year: 2023

description: At a new higher education institution (HEI) in the Caribbean, Blue Waters University (BWU, a pseudonym), significant opportunities and constraints are associated with developing research capacity. BWU has transitioned from a mainly teaching college to a university focused on building a successful research culture. There is limited scholarship on the lived experiences of academic researchers at HEIs that have undergone such transitions. The study reported in this thesis extends the literature on research activities in the Caribbean and contributes to the literature on HEIs in developing economies. The study used a qualitative grounded theory research design informed by an interpretivist research philosophy. The perspectives of Appreciative Inquiry informed the research process. A sample of 18 staff members shared their beliefs, opinions, experiences, and perspectives via semi-structured interviews. Data were collected from interview transcripts, my researcher’s journal, memos, and institutional documents. The conceptual understanding that emerged from the data analysis indicated that BWU academics were constantly working through institutional constraints to accomplish research and improve as professionals. Negotiating professionality for researchers involved a continual process of positive envisioning, persistence and advocacy, and continuous improvement. Positive envisioning required defining research and establishing a researcher's identity. Persistence and advocacy involved navigating institutional challenges and establishing researcher agency. Continuous improvement included the desire to make an impact, instigate change, and pursue professional self-improvement. Key empirical findings show that academics were forming their identities and were in pursuit of scholarly improvement. By embracing the cycle of negotiating professionality, scholars and practitioners at BWU were perpetuating a positive feedback loop of scholarly improvement, the pursuit of academic excellence, and the enhancement of attitudes, behaviours, and intellectual skills.

description: Momentum distributions of quarks/gluons inside a light baryon in a hard exclusive process are encoded in the light-cone distribution amplitudes (LCDAs). In this work, we point out that the leading twist LCDAs of a light baryon can be obtained through a simulation of a quasi-distribution amplitude calculable on lattice QCD within the framework of the large-momentum effective theory. We calculate the one-loop perturbative contributions to LCDA and quasi-distribution amplitudes and explicitly demonstrate the factorization of quasi-distribution amplitudes at the one-loop level. Based on the perturbative results, we derive the matching kernel in the $\overline{\rm MS}$ scheme and regularization-invariant momentum-subtraction scheme. Our result provides a first step to obtaining the LCDA from first principle lattice QCD calculations in the future.

description: Phase is a basic ingredient for quantum states since quantum mechanics uses complex numbers to describe quantum states. In this letter, we introduce a rigorous framework to quantify the phase of quantum states. To do so, we regard phase as a quantum resource, and specify the free states and free operations. We determine the conditions a phase measure should satisfy and provide some phase measures. We also propose the notion of intrinsic phase for quantum states.

description: Bose gas on a two-leg ladder exhibits an interesting topological phase. We show the presence of a bosonic symmetry-protected-topological (SPT) phase protected by $Z_2\times Z_2$ symmetry. This symmetry leads to $Z_4$ fractional quantization of $Z_4$ Berry phase, that is a topological order parameter to identify the bulk. Using the $Z_4$ Berry phase, we have shown that the interacting bosonic system possesses rich topological phases depending on particle density and strength of interaction. Based on the bulk-edge correspondence, each edge state of the SPT phases is discussed in relation to the $Z_4$ Berry phases. Especially we have found an intermediate phase that is not adiabatically connected to a simple adiabatic limit, that possesses unconventional edge states, which we have numerically demonstrate by employing the density-matrix-renormalization group algorithm.

description: We report on an extension of the concept of nonlinear self-repolarization process by means of two different architectures based on dual-Omnipolarizers. More specifically, we compare the performance in terms of polarization attraction capabilities provided by two novel arrangements: The first configuration relies on two cascaded Omnipolarizers, whilst the second architecture integrates an additional device directly into the feedback loop. Our study reveals that for a constant power budget, the cascading of two subsequent Omnipolarizers enables to improve the efficiency of the attraction process, yielding an output Degree-of-Polarization close to unity, but at the cost of twofold equipments.

description: A novel approach, the identity method, was used for particle identification and the study of fluctuations of particle yield ratios in Pb+Pb collisions at the CERN Super Proton Synchrotron (SPS). This procedure allows to unfold the moments of the unknown multiplicity distributions of protons (p), kaons (K), pions ($π$) and electrons (e). Using these moments the excitation function of the fluctuation measure $ν_{\text{\text{dyn}}}$[A,B] was measured, with A and B denoting different particle types. The obtained energy dependence of $ν_{\text{dyn}}$ agrees with previously published NA49 results on the related measure $σ_{\text{dyn}}$. Moreover, $ν_{\text{dyn}}$ was found to depend on the phase space coverage for [K,p] and [K,$π$] pairs. This feature most likely explains the reported differences between measurements of NA49 and those of STAR in central Au+Au collisions.

In (Partial) Defense of Strict Liability in Contract

description: Many scholars believe that notions of fault should and do pervade contract doctrine. Notwithstanding the normative and positive arguments in favor of a fault-based analysis of particular contract doctrines, I argue that contract liability is strict liability at its core. This core regime is based on two key prongs: (1) the promisor is liable to the promisee for breach, and that liability is unaffected by the promisor's exercise of due care or failure to take efficient precautions; and (2) the promisor's liability is unaffected by the fact that the promisee, prior to the breach, has failed to take cost-effective precautions to reduce the consequences of nonperformance. I offer two complementary normative justifications for contract law's stubborn resistance to consider fault in either of these instances. First, I argue that there are unappreciated ways in which courts adherence to strict liability doctrine at the core of contract reduces contracting costs. In addition, I argue that a strict liability core best supports parties efforts to access informal or relational modes of contracting, especially where key information is unverifiable.

description: We study the decay $J/ψ\toπ^{+}π^{-}π^{0}$ within the framework of the Khuri-Treiman equations. We find that the BESIII experimental di-pion mass distribution in the $ρ(770)$-region is well reproduced with a once-subtracted $P$-wave amplitude. Furthermore, we show that $F$-wave contributions to the amplitude improve the description of the data in the $ππ$ mass region around 1.5 GeV. We also present predictions for the $J/ψ\toπ^{0}γ^{*}$ transition form factor.

description: The nature of neutrino masses and the matter-antimatter asymmetry of our universe are two of the most important open problems in particle physics today and are notoriously difficult to test with current technology. Dirac neutrinos offer a solution through a leptogenesis mechanism that hinges on the smallness of neutrino masses and resultant non-thermalization of the right-handed neutrino partners in the early universe. We thoroughly explore possible realizations of this Dirac leptogenesis idea, revealing new windows for highly efficient asymmetry generation. In many of them, the number of relativistic degrees of freedom, $N_\text{eff}$, is severely enhanced compared to standard cosmology and offers a novel handle to constrain Dirac leptogenesis with upcoming measurements of the cosmic microwave background. Realizations involving leptoquarks even allow for low-scale post-sphaleron baryogenesis and predict proton decay. These novel aspects render Dirac leptogenesis surprisingly testable.

Adjacency preservers on invertible hermitian matrices I

subject: FOS: Mathematics

description: Hua's fundamental theorem of geometry of hermitian matrices characterizes all bijective maps on the space of all hermitian matrices, which preserve adjacency in both directions. In this and subsequent paper we characterize maps on the set of all invertible hermitian matrices over a finite field, which preserve adjacency in one direction. This and author's previous result are used to obtain two new results related to maps that preserve the `speed of light' on finite Minkowski space-time. In this first paper it is shown that maps that preserve adjacency on the set of all invertible hermitian matrices over a finite field are necessarily bijective, so the corresponding graph on invertible hermitian matrices, where edges are defined by the adjacency relation, is a core. Besides matrix theory, the proof relies on results from several other mathematical areas, including spectral and chromatic graph theory, and projective geometry.

description: From detailed abundance analysis of >100 Hamburg/ESO candidate extremely metal-poor (EMP) stars we find 45 with [Fe/H] < -3.0 dex. We identify a heretofore unidentified group: Ca-deficient stars, with sub-solar [Ca/Fe] ratios and the lowest neutron-capture abundances; the Ca-deficient group comprises ~ 10% of the sample, excluding Carbon stars. Our radial velocity distribution shows that the carbon-enhanced stars with no s-process enhancements, CEMP-no, and which do not show C2 bands are not preferentially binary systems. Ignoring Carbon stars, approximately 15% of our sample are strong (> 5 sigma) outliers in one, or more, elements between Mg and Ni; this rises to ~19% if very strong (>10 sigma) outliers for Sr and Ba are included. Examples include: HE0305-0554 with the lowest [Ba/H] known; HE1012-1540 and HE2323-0256, two (non-velocity variable) C-rich stars with very strong [Mg,Al/Fe] enhancements; and HE1226-1149 an extremely r-process rich star.

description: Squeezed light is a crucial resource for continuous-variable (CV) quantum information science. Distributed multi-mode squeezing is critical for enabling CV quantum networks and distributed quantum sensing. To date, multi-mode squeezing measured by homodyne detection has been limited to single-room experiments without coexisting classical signals, i.e., on ``dark'' fiber. Here, after distribution through separate fiber spools (5~km), $-0.9\pm0.1$-dB coexistent two-mode squeezing is measured. Moreover, after distribution through separate deployed campus fibers (about 250~m and 1.2~km), $-0.5\pm0.1$-dB coexistent two-mode squeezing is measured. Prior to distribution, the squeezed modes are each frequency multiplexed with several classical signals -- including the local oscillator and conventional network signals -- demonstrating that the squeezed modes do not need dedicated dark fiber. After distribution, joint two-mode squeezing is measured and recorded for post-processing using triggered homodyne detection in separate locations. This demonstration enables future applications in quantum networks and quantum sensing that rely on distributed multi-mode squeezing.

description: We compare the properties of giant molecular clouds (GMCs) in M51 identified by the Plateau de Bure Interferometer Whirlpool Arcsecond Survey (PAWS) with GMCs identified in wide-field, high resolution surveys of CO emission in M33 and the Large Magellanic Cloud (LMC). We find that GMCs in M51 are larger, brighter and have higher velocity dispersions relative to their size than equivalent structures in M33 and the LMC. These differences imply that there are genuine variations in the average mass surface density of the different GMC populations. To explain this, we propose that the pressure in the interstellar medium surrounding the GMCs plays a role in regulating their density and velocity dispersion. We find no evidence for a correlation between size and linewidth in any of M51, M33 or the LMC when the CO emission is decomposed into GMCs, although moderately robust correlations are apparent when regions of contiguous CO emission (with no size limitation) are used. Our work demonstrates that observational bias remains an important obstacle to the identification and study of extragalactic GMC populations using CO emission, especially in molecule-rich galactic environments.
