description: Multi-class colorectal tissue classification is a challenging problem that is typically addressed in a setting, where it is assumed that ample amounts of training data is available. However, manual annotation of fine-grained colorectal tissue samples of multiple classes, especially the rare ones like stromal tumor and anal cancer is laborious and expensive. To address this, we propose a knowledge distillation-based approach, named KD-CTCNet, that effectively captures local texture information from few tissue samples, through a distillation loss, to improve the standard CNN features. The resulting enriched feature representation achieves improved classification performance specifically in low data regimes. Extensive experiments on two public datasets of colorectal tissues reveal the merits of the proposed contributions, with a consistent gain achieved over different approaches across low data settings. The code and models are publicly available on GitHub.

description: Device identification is the process of identifying a device on Internet without using its assigned network or other credentials. The sharp rise of usage in Internet of Things (IoT) devices has imposed new challenges in device identification due to a wide variety of devices, protocols and control interfaces. In a network, conventional IoT devices identify each other by utilizing IP or MAC addresses, which are prone to spoofing. Moreover, IoT devices are low power devices with minimal embedded security solution. To mitigate the issue in IoT devices, fingerprint (DFP) for device identification can be used. DFP identifies a device by using implicit identifiers, such as network traffic (or packets), radio signal, which a device used for its communication over the network. These identifiers are closely related to the device hardware and software features. In this paper, we exploit TCP/IP packet header features to create a device fingerprint utilizing device originated network packets. We present a set of three metrics which separate some features from a packet which contribute actively for device identification. To evaluate our approach, we used publicly accessible two datasets. We observed the accuracy of device genre classification 99.37% and 83.35% of accuracy in the identification of an individual device from IoT Sentinel dataset. However, using UNSW dataset device type identification accuracy reached up to 97.78%.

description: Human society under the COVID-19 pandemic can be viewed as a complex system, the evolution of which is characterized by such the parameters as the number of newly diseased, the number of seriously ill patients, the number of those who were identified as diseased, etc. To analyze such a complex system, we propose to apply the methodology known in statistical physics as the methodology of the \emph {mean first-passage times}. As will be shown, this methodology makes it possible to determine properly the so-called threshold, at which a spreading viral disease goes into an epidemic regime with accelerated progression. The efficiency of the methodology is demonstrated by the example of data analysis on the spread of the COVID-19 in the Russian Federation as well as separately in one of the regions of the Russian Federation. The methodology can serve as an additional useful tool for solving optimization problems.

description: We analyze the resonant inelastic x-ray scattering (RIXS) spectra at the Ni $K$ edge in an antiferromagnetic insulator NiO by applying the theory developed by the present authors. It is based on the Keldysh Green's function formalism, and treats the core-hole potential in the intermediate state within the Born approximation. We calculate the single-particle energy bands within the Hartree-Fock approximation on the basis of the multi-orbital tight-binding model. Using these energy bands together with the $4p$ density of states from an ab initio band structure calculation, we calculate the RIXS intensities as a function of energy loss. By taking account of electron correlation within the random phase approximation (RPA), we obtain quantitative agreement with the experimental RIXS spectra, which consist of prominent two peaks around 5 eV and 8 eV, and the former shows considerable dispersion while the latter shows no dispersion. We interpret the peaks as a result of a band-to-band transition augmented by the RPA correlation.

description: We further characterize the structures tentatively identified on thermal and chemical grounds as the sites of dissipation of turbulence in molecular clouds (Papers I and II). Our study is based on two-point statistics of line centroid velocities (CV), computed from three large 12CO maps of two fields. Probability density functions (PDF) of the CO line centroid velocity increments (CVI) over lags varying by an order of magnitude and structure functions of the line CV, up to the 6th order, are computed. We show that the line CV bear the three signatures of intermittency in a turbulent velocity field: (1) the non-Gaussian tails in the CVI PDF grow as the lag decreases, (2) the departure from Kolmogorov scaling of the high-order structure functions is more pronounced in the more turbulent field, (3) the positions contributing to the CVI PDF tails delineate narrow filamentary structures (thickness ~ 0.02 pc), uncorrelated to dense gas structures and spatially coherent with thicker ones (~0.18 pc) observed on larger scales. The confrontation with theoretical predictions leads us to identify these small-scale filamentary structures with extrema of velocity-shears associated with gas warmer than the bulk. Last, their average direction is parallel (or close) to that of the local magnetic field projection. Turbulence in these translucent fields exhibits the statistical and structural signatures of small-scale and inertial-range intermittency. The more turbulent field on the 30 pc-scale is also the more intermittent on small scales. The small-scale intermittent structures coincide with those formerly identified as sites of enhanced dissipation. They are organized into parsec-scale coherent structures, coupling a broad range of scales.

description: Hole doping in Nd${}_{2}$NiO${}_{4.00}$ can be either achieved by substituting the trivalent Nd atoms by bivalent alkaline earth metals or by oxygen doping, yielding Nd${}_{2}$NiO${}_{4+δ}$. In this study, we investigated the interplay between oxygen and spin ordering for a low oxygen doping concentration i.e. Nd${}_{2}$NiO${}_{4.10}$. Although the extra oxygen doping level remains rather modest with only one out of 20 possible interstitial tetrahedral lattice sites occupied, we observed by single crystal neutron diffraction the presence of a complex 3D modulated structure related to oxygen ordering already at ambient, the modulation vectors being $\pm$2/13\textit{\textbf{a*}}$\pm$3/13\textit{\textbf{b*}}, $\pm$3/13\textit{\textbf{b*}}$\pm$2/13\textit{\textbf{b*}} and $\pm$1/5\textit{\textbf{a*}}$\pm$1/2\textit{\textbf{c*}} and satellite reflections up to fourth order. Temperature dependent neutron diffraction studies indicate the coexistence of oxygen and magnetic ordering below T${}_{N}$ $\simeq$ 48 K, the wave vector of the Ni sublattice being \textbf{\textit{k}}=(100). In addition, magnetic satellite reflections adapt exactly the same modulation vectors as found for the oxygen ordering, evidencing a unique coexistence of 3D modulated ordering for spin and oxygen ordering in Nd${}_{2}$NiO${}_{4.10}$. Temperature dependent measurements of magnetic intensities suggest two magnetic phase transitions below 48 K and 20 K, indicating two distinct onsets of magnetic ordering for the Ni and Nd sublattice, respectively.

description: Observations of the temperature anisotropies in the Cosmic Microwave Background (CMB) radiation show that the models of inflation with the monomial potentials are inconsistent with the allowed $n_s-r$ bounds. However certain monomial potentials of inflation are allowed in the context of \textit{Warm Inflation}, where the inflaton's coupling with other fields are significant both \textit{during and after} the inflationary phase. In our study, we consider $λϕ^4$ and $λϕ^6$ models of warm inflation with different forms of the inflaton dissipation coefficient. We parameterize the primordial power spectrum in terms of the model parameters, namely, the inflaton self coupling, $λ$, and the dissipation parameter, $Q_P$, due to inflaton's interaction with the other fields. Then we obtain the joint and marginal distributions of these parameters by carrying out a Markov Chain Monte Carlo (MCMC) analysis using the {\tt CosmoMC} numerical code. An estimation of these physical parameters is essential for model building. We also obtain the $n_s$ and $r$ values for the mean values of the parameters and find them to be consistent with the observational bounds, confirming that these simple models are viable models for describing inflation.

title: The Eurozone crisis and the ‘intermediate’ economies: the political economies of Greece and Portugal
Creators: name: Myrodias, Konstantinos
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2020

description: It is well documented that the EU and IMF bailout programmes led the crisis-hit Eurozone countries to a weak economic recovery. However, the existing theories have so far failed to provide comprehensive explanations of the post-crisis economic performance in the periphery of the Eurozone. This thesis’ starting point is to identify what policies were introduced in Greece and Portugal and how effective they were at addressing the causes of the crisis. To answer this question, it draws on qualitative primary data, documents, archives, and elite interviews. In contrast to the neoclassical explanation that stresses the ‘backwardness’ of the countries in the periphery, as well as more critical Keynesian/‘victimisation’ approaches that understand the crisis-hit countries as ‘victims’ of the creditors, this thesis -by building upon Comparative Political Economy literature- provides a Growth Model explanation of the crisis and the post-crisis economic performance of Greece and Portugal. It shows why the EU and IMF internal devaluation policies failed to boost export-led growth in both countries and brings to light the much overlooked ways in which Greece and Portugal have been through a productive transformation in recent decades. The Growth Model perspective goes beyond the VoC literature, showing how the historical capital formation (i.e. the difficulty of creating economies of scale, and low-added value production), the fiscal policies, and the European and international economic developments (i.e. EU Eastern Enlargement, and the rise of the large-scale emerging economies in Asia) led Greece and Portugal into an ‘intermediate’ trap. The ‘politics’ of the crisis management -based on the neoclassical versus ‘victimisation’ narratives- reinforced the ‘intermediate’ status of Greece and Portugal after the crisis. Although the existing literature tends to focus on the creditor’s role in the management of the crisis, this thesis brings evidence from the EU-IMF bailout negotiations showing that both the creditors and the anti-austerity governments in the debtor countries kept the structural aspects of the crisis out of the negotiations to maintain the status quo in the Eurozone. Overall, this thesis brings the Growth Model perspective and VoC into a productive dialogue, contributing the concept of the ‘intermediate’ economies to the European Political Economy.
Design and development of magnetostrictive actuator

Publisher: name: University of British Columbia
Year: 2009

description: In this joint project between NRC and UBC, the author has developed an actuator using Terfenol-D, an optical precision displacement sensor, and a few control strategies. These control strategies include proportional-plus-integral-plus-derivative (PID), cascaded PID, and sliding mode control strategies. Each of these controllers was designed and tested experimentally on the actuator. The controllers were very difficult to design because the dynamics of Terfenol-D has hysteresis. The system with the designed PID controller showed sign of instability under load. However, the designed cascaded PID and the designed discrete-time sliding mode controllers are capable of controlling the actuator under loaded condition and fulfilling the requirements of NRC. Real-time experimental results are attached in chapter 5.

description: Using a sample of ~15,000 kpc-scale star-forming spaxels in 28 galaxies drawn from the ALMA-MaNGA QUEnching and STar formation (ALMaQUEST) survey, we investigate the galaxy-to-galaxy variation of the `resolved' Schmidt-Kennicutt relation (rSK; Sigma_H2 - Sigma_SFR), the `resolved' star forming main sequence (rSFMS; Sigma_* - Sigma_SFR) and the `resolved' molecular gas main sequence (rMGMS; Sigma_* - Sigma_H2). The rSK relation, rSFMS and rMGMS all show significant galaxy-to-galaxy variation in both shape and normalization, indicating that none of these relations is universal between galaxies. The rSFMS shows the largest galaxy-to-galaxy variation and the rMGMS the least. By defining an `offset' from the average relations, we compute a Delta_rSK, Delta_rSFMS, Delta_rMGMS for each galaxy, to investigate correlations with global properties. We find the following correlations with at least 2 sigma significance: the rSK is lower (i.e. lower star formation efficiency) in galaxies with higher M_*, larger Sersic index and lower specific SFR (sSFR); the rSFMS is lower (i.e. lower sSFR) in galaxies with higher M_* and larger Sersic index; the rMGMS is lower (i.e. lower gas fraction) in galaxies with lower sSFR. In the ensemble of all 15,000 data points, the rSK relation and rMGMS show equally tight scatters and strong correlation coefficients, compared with a larger scatter and weaker correlation in the rSFMS. Moreover, whilst there is no correlation between Delta_rSK and Delta_rMGMS in the sample, the offset of a galaxy's rSFMS does correlate with both of the other two offsets. Our results therefore indicate that the rSK and rMGMS are independent relations, whereas the rSFMS is a result of their combination.

description: Open-source software utilizes collaborative practices to engage communities and enhance the diversity of knowledge and knowledge producers. Despite the diverse sets of goals and challenges across sectors and disciplines, open source helps provide equitable access to technology and aims to make knowledge freely available for global benefit. Despite the tremendous progress, many questions in open source remain: How to build an open culture where diverse stakeholders of society participate not just in accessing knowledge, but in its production, circulation, and societal benefit? How to embed the DEI principles? How to reduce and tackle the environmental harms of technology?To answer these, I turn to the Do No Harm principle and apply it to open source/science work.

description: The ability to control carrier concentration based on the extent of Cu solubility in the $\mathrm{Cu_{2x}Hg_{2-x}GeTe_4}$ alloy compound (where 0 $\leq$ x $\leq$ 1) makes $\mathrm{Cu_{2x}Hg_{2-x}GeTe_4}$ an interesting case study in the field of thermoelectrics. While Cu clearly plays a role in this process, it is unknown exactly how Cu incorporates into the $\mathrm{Cu_{2x}Hg_{2-x}GeTe_4}$ crystal structure and how this affects the carrier concentration. In this work, we use a combination of resonant energy X-ray diffraction (REXD) experiments and density functional theory (DFT) calculations to elucidate the nature of Cu incorporation into the $\mathrm{Cu_{2x}Hg_{2-x}GeTe_4}$ structure. REXD across the $\mathrm{Cu_k}$ edge facilitates the characterization of Cu incorporation in the $\mathrm{Cu_{2x}Hg_{2-x}GeTe_4}$ alloy and enables direct quantification of anti-site defects. We find that Cu substitutes for Hg at a 2:1 ratio, wherein Cu annihilates a vacancy and swaps with a Hg atom. DFT calculations confirm this result and further reveal that the incorporation of Cu occurs preferentially on one of the z = 1/4 or z = 3/4 planes before filling the other plane. Furthermore, the amount of $\mathrm{Cu_{Hg}}$ anti-site defects quantified by REXD was found to be directly proportional to the experimentally measured hole concentration, indicating that the $\mathrm{Cu_{Hg}}$ defects are the driving force for tuning carrier concentration in the $\mathrm{Cu_{2x}Hg_{2-x}GeTe_4}$ alloy. The link uncovered here between crystal structure, or more specifically anti-site defects, and carrier concentration can be extended to similar cation-disordered material systems and will aid the development of improved thermoelectric and other functional materials through defect engineering.

description: A superconducting (SC) state (Tc ~ 4.2K) has very recently been observed upon successful doping of the CDW ordered triangular lattice TiSe$_2$, with copper. Using high resolution photoemission spectroscopy we identify, for the first time, the momentum space locations of the doped electrons that form the Fermi sea of the parent superconductor. With doping, we find that the kinematic nesting volume increases whereas the coherence of the CDW order sharply drops. In the superconducting doping, we observe the emergence of a large density of states in the form of a narrow electron pocket near the \textit{L}-point of the Brillouin Zone with \textit{d}-like character. The \textit{k}-space electron distributions highlight the unconventional interplay of CDW to SC cross-over achieved through non-magnetic copper doping.

Open real-time operating system for CNC machine tools
Creators: name: Erol, Neset Arda
Publisher: name: University of British Columbia
Year: 2009

description: An open architecture real time operating system is developed for Computer Numerical Control (CNC) machine tools. The system has two independent modules, one for general motion and process control, and the other for process control and sensor signal processing tasks only. The two systems can be integrated with each other, and both can be used for general real time applications other than CNC systems as well. Both systems are implemented on multiple digital signal processing (DSP) boards connected to a host computer via ISA or PCI bus. All real-time processing is done on the DSP boards. The host computer is used as an interface between multiple DSP boards. The first system, IMM, provides a fast data flow structure, which can accommodate user modules. Some process control and signal processing modules have been developed on IMM, to provide an intelligent machining subsystem.- The second system, ORTS, is a combination of a real-time DSP operating system and an integrated host software that runs on Windows NT operating system. An open CNC system, along with several process control modules, is implemented on ORTS, to make it a standalone sensor-assisted CNC system, which can also be integrated with external process control and monitoring applications. Both IMM and ORTS are configured at runtime via a scripting language. The developed open CNC system allows local or remote software components to manipulate CNC parameters such as feed, control parameters, and target position. The open and modular architecture of the controller also allows individual modules, such as motion control and interpolation algorithms, to be replaced with custom algorithms. This open approach allows easy integration of custom process and motion control algorithms, which can either be implemented internally within the developed real-time DSP operating system, or externally as standalone Windows NT applications. The proposed system allows rapid design and reconfiguration of motion control, process control, and signal processing applications.

description: We present constraints on the evolution of the virial to stellar mass ratio of galaxies with high stellar masses in the redshift range 0.2 10.5, where the majority show an early-type morphology, we find that the virial mass to stellar mass ratio is given by M_vir/M_star = 53^{+13}_{-16}. Assuming a baryon fraction from the concordance cosmology, this corresponds to a stellar fraction of baryons in massive galaxies of Omega_b^*/Ω_b = 0.10 +/- 0.03. Analysing the galaxy sample in different redshift slices, we find little or no evolution in the virial to stellar mass ratio, and place an upper limit of ~2.5 on the growth of massive galaxies through the conversion of gas into stars from z=0.8 to the present day.

A novel computational paradigm for a precise determination of the hadronic contribution to $(g_μ-2)$ from lattice QCD

description: The hadronic contribution to the muon anomalous magnetic moment $a_μ=(g_μ-2)/2$ has to be determined at the per-mille level for the Standard Model prediction to match the expected final uncertainty of the ongoing E989 experiment. That is 3 times better than the current precision from the dispersive approach, and 5-15 times smaller than the uncertainty based on the purely theoretical determinations from lattice QCD. So far the stumbling-block is the large statistical error in the Monte Carlo evaluation of the required correlation functions which can hardly be tamed by brute force. In this talk we present our proposal to solve this problem by multi-level Monte Carlo integration, a technique which reduces the variance of correlators exponentially in the distance of the fields. We report the results of our feasibility tests for the computation of the Hadronic Vacuum Polarization on a lattice with a linear extension of 3~fm, a spacing of 0.065 fm, and a pion mass of 270 MeV. Indeed the two-level integration makes the contribution to the statistical error from long-distances de-facto negligible by accelerating its inverse scaling with the cost of the simulation. These findings establish multi-level Monte Carlo as a solid and efficient method for a precise lattice determination of the hadronic contribution to $a_μ$.

description: Rattling phonon modes are known to be origin of various anomalous physical properties such as superconductivity, suppression of thermal conductivity, enhancement of specific heat etc. By means of DFT+$U$ calculations we directly show presence of the rattling mode in the quadruple perovskites CuCu$_3$V$_4$O$_{12}$ and CuCu$_3$Fe$_2$Re$_2$O$_{12}$ and argue that this can develop in others as well. It is demonstrated that Cu ions at $A$ sites vibrate in the center of the icosahedral oxygen O$_{12}$ cages and the corresponding potential has a complicated form with many local minima.

description: In this paper, the sizes of the BLRs and BH masses of DouBle-Peaked broad low-ionization emission line emitters (dbp emitters) are compared using different methods: virial BH masses vs BH masses from stellar velocity dispersions, the size of BLRs from the continuum luminosity vs the size of BLRs from the accretion disk model. First, the virial BH masses of dbp emitters estimated by the continumm luminosity and line width of broad H$β$ are about six times (a much larger value, if including another dbp emitters, of which the stellar velocity dispersions are traced by the line widths of narrow emission lines) larger than the BH masses estimated from the relation $M_{BH} - σ$ which is a more accurate relation to estimate BH masses. Second, the sizes of the BLRs of dbp emitters estimated by the empirical relation of $R_{BLR} - L_{5100Å}$ are about three times (a much larger value, if including another dbp emitters, of which the stellar velocity dispersions are traced by the line widths of narrow emission lines) larger than the mean flux-weighted sizes of BLRs of dbp emitters estimated by the accretion disk model. The higher electron density of BLRs of dbp emitters would be the main reason which leads to smaller size of BLRs than the predicted value from the continuum luminosity.

title: Cooperation against the odds: a study on the political economy of local development in a country with small firms and small farms

description: Is it possible to get economic actors to work together in order to achieve mutually beneficial outcomes in unfavourable settings? Established theories of cooperation suggest that overcoming the obstacles to cooperation requires either a robust framework of formal institutions or a long-established culture of trust. Many places in the world are endowed with neither of those characteristics. Yet, in the presence of fragmented ownership structures, sustained cooperation among economic actors is important for processes of economic development, which themselves have major implications for domestic political dynamics. My dissertation approaches the puzzle of the emergence of cooperation in unfavourable settings by drawing on qualitative empirical evidence collected through fieldwork in four areas of Greece where specific types of cooperation were observed, compared to four otherwise similar (matching) cases where such patterns of cooperation failed to occur. I argue that for cooperation to emerge against the odds, the crucial variable is leadership. A small group of boundary-spanning leading actors can trigger a process of creating local-level cooperative institutions by performing three specific types of difficult and costly institutional work. Successful leaders tend to be translocally embedded, highly skilled, well connected actors, who have a subjective conception of their self-interest as encapsulating the interests of others. The institutional work of a small group of local-level leading actors can only catalyse broad-based, sustained cooperation if it is nested within a framework of facilitative overarching institutions. Crucially, supranational actors such as the EU can also provide such facilitative macro-level institutions, thereby to an extent compensating for deficiencies in national institutional frameworks. By combining analysis of local-level agency and processes, on the one hand, and macro-level institutional frameworks, on the other, my thesis makes a contribution to our understanding of institutional change, the emergence of cooperation, and the political economy of local development in fragmented economies.

description: In stars with temperatures above 20*10^6 K, hydrogen burning is dominated by the CNO cycle. Its rate is determined by the slowest process, the 14N(p,gamma)15O reaction. Deep underground in Italy's Gran Sasso laboratory, at the LUNA 400 kV accelerator, the cross section of this reaction has been measured at energies much lower than ever achieved before. Using a windowless gas target and a 4pi BGO summing detector, direct cross section data has been obtained down to 70 keV, reaching a value of 0.24 picobarn. The Gamow peak has been covered by experimental data for several scenarios of stable and explosive hydrogen burning. In addition, the strength of the 259 keV resonance has been remeasured. The thermonuclear reaction rate has been calculated for temperatures 90 - 300 *10^6 K, for the first time with negligible impact from extrapolations.
Hepatic vascular network segmentation for liver surgery planning
Creators: name: Benis, Olivér
Publisher: name: Zenodo

description: Locating the blood vessels in the liver is a crucial task for surgery planning. Liver resection is performed to remove tumors from the organ or for transplantation. The location of the cut is selected with taking the position of the vessels into account to ensure intact blood flow after the surgery. Contrast enhanced computed tomography is suitable to be used for vessel network segmentation. Doing this process manually is time consuming and prone to errors, therefore in the recent years both traditional and deep learning based methods were proposed for automatic vessel extraction.
 During my work I have developed a new method for automatic liver vessel network segmentation that is based on a marked point process (MPP) model and region growing algorithm. A synthetically generated training dataset was created consisting of artificial
 CT images and the vascular network was annotated by the program during the generation process which means that neither real CT images nor manual segmentation was required. The model parameters can be determined fully automatically using a low number of
 training images of the synthetic CT scan dataset. The low number of parameters give us the possibility to modify the model if adaptation is needed for a new dataset, with possibly different CT image characteristics. The method was tested on multiple CT image datasets both qualitatively and quantitatively and it was compared to other methods. Based on the experiments, the technique is showing promising results: while it is easily trainable it also comes near to the state-of-the-art performance. The adaptivity and robustness of the proposed 3D vessel network extraction algorithm was also demonstrated with testing its applicability for vessel segmentation in the lungs. As the liver resection surgery planning depends directly on the precisely delineated liver segments I have developed a method that is able to locate these segments using the liver vascular network data. Only minimal human interaction is needed for the algorithm to perform its task and after selecting the subtree of the vessel network for each segment, the liver voxels are classified into one of the segments.

description: We investigate relation between Dehn fillings and commensurability of hyperbolic 3-manifolds. The set consisting of the commensurability classes of hyperbolic 3-manifolds admits the quotient topology induced by the geometric topology. We show that this quotient space satisfies some separation axioms. Roughly speaking, this means that commensurablity classes are sparsely distributed in the space consisting of the hyperbolic 3-manifolds.

description: In order to investigate the role of gas in the demise of star formation on kpc-scales, we compare the resolved molecular gas main sequence (rMGMS: Sigma_* vs Sigma_H2) of star-forming regions to the sequence of `retired' regions that have ceased to form new stars. Using data from the ALMaQUEST survey, we find that retired spaxels form a rMGMS that is distinct from that of star-forming spaxels, offset to lower Sigma_H2 at fixed Sigma_* by a factor of ~5. We study the rMGMS of star-forming and retired spaxels on a galaxy-by-galaxy basis for eight individual ALMaQUEST galaxies. Six of these galaxies have their retired spaxels concentrated within the central few kpc. Molecular gas is detected in 40-100% of retired spaxels in the eight galaxies in our sample. Both the star-forming and retired rMGMS show a diversity in normalization from galaxy-to-galaxy. However, in any given galaxy, the rMGMS for retired regions is found to be distinct from the star-forming sequence and gas fractions of retired spaxels are up to an order of magnitude lower than the star-forming spaxels. We conclude that quenching is associated with a depletion (but not absence) of molecular gas via a mechanism that typically begins in the centre of the galaxy.
