description: In recent years, the jet formation region in active galaxies has been imaged through mm-VLBI in few ideal targets, first and foremost M87. An important leap forward for understanding jet launching could be made by identifying a larger number of suitable objects, characterized by different accretion modes and jet powers. In this article, we present 1 cm and 7 mm VLBI data of a sample of 16 poorly explored radio galaxies, comprising both High-Excitation (HEG) and Low-Excitation Galaxies (LEG) and spanning a large range in radio power. The combination of the sources vicinity (z<0.1) with a large black hole mass ($\log{M_{\rm BH}}$>8.5) results in a high spatial resolution in units of Schwarzschild radii ($<10^3-10^4$ $R_{\rm S}$), necessary for probing the region where the jet is initially accelerated and collimated. We aim at identifying the best candidates for follow-up observations with current and future VLBI facilities. The observations were performed with the High Sensitivity Array, including Effelsberg and the phased-VLA, which has allowed us to characterize the sub-parsec properties of these faint jets and to estimate their core brightness temperature and orientation. The number of sources imaged on scales $\lesssim 10^3$ $R_{\rm S}$ is more than doubled by our study. All targets were detected at both frequencies, and several present two-sided jet structures. Several LEG jets show hints of limb-brightening. The core brightness temperatures are generally below the equipartition value, indicating that equipartition has not yet been reached and/or that the emission is de-boosted. Among LEG, we identify 3C31, 3C66B, and 3C465 as the most promising, combining a relatively high flux density (>50 mJy) with superb spatial resolution (<500 $R_{\rm S}$) at 7 mm. The powerful HEG 3C452 is interesting as well due to its highly symmetric, two-sided jet base.

description: This article is based on an unpublished master's thesis of the same title from 2021 at the University of Duisburg-Essen. The management of a company's inventory plays a critical function in most businesses. Without a robust management structure, long-term profitability can be harmed due to increased inefficiencies. This research will look at how warehousing and inventory management might impact a company's competitiveness against current and potential market competitors. Warehouse management is an important part of a company's manufacturing and logistics processes since it keeps raw materials, parts, in-process products, and finished items between origin and consumption. The continuously evolving consumer products industry in Germany is large and complex to manage across the area. As a result, Iconsidered Vivere GmbH, a Hamburg-based firm, and gathered the information listed below. This research is based on on-the-ground research in one of Germany's fast-moving consumer products industries. Vivere GmbH is the most prominent maker of basic consumer goods. A variety of senior staff employees from the representative domain level were questioned, revealing warehouse management and supply chain integration challenges as well as opportunities. As a result, my company gathers the information provided in this project. Because it includes a work process of how inventory management might be productive, this study is both theoretically and practically valuable. Production managers may simply coordinate other services to strengthen the supply chain and improve company competition through inventory management optimization.

description: JWST is detecting an excess of high-redshift ($z\gtrsim 10$), bright galaxies challenging most theoretical predictions. To address this issue, we investigate the impact of Primordial Black Holes (PBHs) on the halo mass function and UV luminosity function (LF) of super-early galaxies. We explore two key effects: (i) the enhancement of massive halos abundance due to the compact nature and spatial distribution of PBHs, and (ii) the luminosity boost, characterized by the Eddington ratio $λ_E$, due to Active Galactic Nuclei (AGN) powered by matter accretion onto PBHs. We build an effective model, calibrated using data at lower redshifts ($z\approx 4-9$), to derive the evolution of the LF including the additional PBH contribution. Via Bayesian analysis, we find that: (a) Although a small fraction ($\log f_{\rm PBH} \approx -5.42$) of massive ($\log M_{\rm PBH} / {\rm M_{\odot}} \approx 8.37$), non-emitting ($λ_E=0$) PBHs can explain the galaxy excess via the halo abundance enhancement, this solution is excluded by CMB $μ$-distortion constraints on monochromatic PBHs. (b) If PBHs power an AGN emitting at super-Eddington luminosity ($λ_E \approx 10$), the observed LF can be reproduced by a PBH population with characteristic mass $\log M_{\rm PBH} / {\rm M_{\odot}} \approx 3.69$ constituting a tiny ($\log f_{\rm PBH} \approx -8.16$) fraction of the cosmic dark matter content. In the AGN scenario, about 75% of the observed galaxies with ${\rm M_{UV}}=-21$ at $z=11$ should host a PBH-powered AGN and typically reside in low mass halos, $M_h = 10^{8-9} {\rm M_{\odot}}$. These predictions can be tested with available and forthcoming JWST spectroscopic data. We note that our analysis considers a lognormal PBH mass function and compares its parameters with monochromatic limits on PBH abundance. Further work is required to relax such limitations.

The impact of sanding grit size on color consistency of different wood species used in Canadian furniture manufacturing : a visual inspection
Creators: name: Firoozmand, Mohammad
Publisher: name: The University of British Columbia
Year: 2013

description: Wood finishing consists of several preparation steps to the aesthetic appearance of wood and also to protect it from damage. In the very first step of finishing, wood defects such as oil, imperfections, and indentations are removed from the surface using multiple grits of sandpaper. Once the surface has been sanded, stain and finish can be applied evenly to the wooden surface. The natural color and cellular structure of each wood determine the final result of finishing. Open-grain woods such as oak usually have large pores, they absorb stains very easily and they do not turn blotchy. On the other hand, woods with closed grain structure like cherry and maple have small and dense pores, they do not absorb stain easily and evenly, and they tend to turn blotchy no matter to what grit they are sanded with. Other influential factors on the final result of finishing are stain type and the final sanding grit. To achieve the best results, each wood should be sanded with proper grit size, and finished with appropriate stains and finishes. In this study, I investigate the impact of sanding grit size on the color consistency of finished wood. For this purpose, samples of seven hardwood and softwood species were sanded using 120, 150, and 180 grit sandpapers, the stain was applied to the sanded wood surfaces using two methods, spraying and wiping stains, and finally the wood was finished with lacquer. For each individual wood species, the combination of grit size and staining method that achieved the best color consistency is reported.

description: Accretion from protoplanetary or debris disks can contaminate the stellar photosphere, which is detectable in stars with radiative envelopes due to relatively slower photospheric mixing. The contaminated photosphere reflects ongoing disk processes, detectable through stellar spectroscopy. We investigate the composition of six gas-rich debris disk-hosting A-type stars to understand possible links with their debris disk or earlier accretion stages. We used archival spectra to estimate the stellar parameters and abundances of our sample. We also estimated the stellar photospheric accretion contamination parameter, fph which indicates the fraction of accreting material on the stellar photosphere. The oxygen abundance in intermediate-mass stars decreases with age until the debris disk stage (< 20 Myr). The downward trend could result from H2O ice accumulating in dust traps or the formation of hydrated asteroids in the protoplanetary disk, locking oxygen in solids and reducing its accretion onto the star. All stars have similar volatile abundances (C, O), but HD 110058 and HD 32297 show refractory depleted abundances. The near-zero fph values in the six stars suggest that any currently accreted gas would not overwhelm mixing in the photosphere and would not impact the observed composition. The refractory depleted abundances in HD 110058 and HD 32297 suggest residual, or even chronic, accretion contamination from their earlier protoplanetary stages when the accretion rates were about five orders of magnitude higher. For HD 110058, with the highest refractory depletion, we estimated a lower limit on its earlier protoplanetary accretion rate of 9 x 10^(-8) Msun/yr, similar to other Herbig stars and equal to the Herbig star - HD 100546. This supports our hypothesis that refractory depletion in HD 110058 originates from a prior phase of higher accretion of dust-poor material.

Industrialization of the construction industry through prefabrication and adoption of current technologies
Creators: name: Grills, Chantelle
Publisher: name: The University of British Columbia
Year: 2013

description: In the current construction industry, conventional, on-site building methods are much more prevalent than off-site building methods, such as prefabrication. Prefabrication is the construction of building assemblies or sub-assemblies in a factory and then transporting them to site. The use of prefabrication in construction dates back to the mid-1800s, but has yet to gain wide-spread adoption in the industry. Today, prefabrication is once again gaining popularity, driven by the inherent benefits associated with the construction method, as well as global environmental and social factors. Prefabrication is also being seen as a means of improving the industrialization of the construction industry. The advantages of prefabrication address many of the concerns associated with conventional construction methods - skilled-labour intensive, has variable quality, is inefficient, and has high environmental impacts. In prefabrication, construction is performed in a factory, allowing for the use of automated equipment to reduce labour and full-time factory employees ensure that project delays due to the unavailability of skilled tradespeople are avoided. Improved product quality is achieved through highly sophisticated equipment, better supervision, and climatic protection. Factory fabrication results in improved efficiency, ultimately reducing costs. Environmentally-sustainable principles are also incorporated into prefabrication, most importantly the reduction of construction waste. Many of the benefits offered by prefabrication have already been realized in other manufacturing industries through industrialization. Industrialization is the replacement of crafts-based production processes with more standardized, machine-based processes. In the construction industry, prefabrication is seen as the first degree of industrialization, followed by mechanization, automation, robotics, and reproduction. With implementation of current systems and technologies and a greater environmental awareness, industrialization of the construction industry can be attainable.

description: The magnetic field morphology of relativistic jets can be studied with circular polarization (CP). Recent 3D relativistic magnetohydrodynamic (RMHD) simulations coupled with radiative transfer calculations make strong predictions about the level (and morphology) of the jet's CP emission. These simulations show that the sign of CP and the electric vector position angle (EVPA) are both sensitive to the jet's magnetic field morphology within the radio core. We probe this theory by exploring if the jet's radio core EVPA orientation is consistent with the observed sign of the core CP in deep full-track polarimetric observations. We aim to probe the nature of linear polarization and CP in the innermost regions of jets from a small sample of nine blazars. This sample includes sources that have exhibited: (i) positive CP, (ii) negative CP, or (iii) positive & negative CP simultaneously in the radio core region. Nine blazar sources were observed using the VLBA at both 15 GHz and 23 GHz. Our self-calibration relies on a physically based model applied in DoG-HiT resulting in more accurate gains. We consider compact Stokes V structures instead of assuming it to be zero, which is crucial given the significant non-zero CP fraction observed at long baselines. We observe robust, relatively high degrees of fractional circular polarization m_c=(0.32 +- 0.2)% at 15 GHz and m_c=(0.59 +-0.56)% at 23 GHz. We observe consistent polarized structure and EVPA orientation over time when comparing our analysis with archival MOJAVE data. Theoretical predictions indicate a clear favored toroidal magnetic field orientation within the extended jet emission of the reconstructed signal of the blazar 0149+218. The jet structures of 1127-145 and 0528+134, even in superresolution, exhibit characteristics aligned with helical or poloidal magnetic nature.

description: We study the transition rates of an atom rotating in a circular orbit, which is coupled with fluctuating electromagnetic fields in vacuum. We find that when the rotational angular velocity exceeds the transition frequency of the atom, the excitation rate can reach the same order of magnitude as the emission rate, even with an extremely low centripetal acceleration resulting from a very small orbital radius. For experimentally accessible centripetal accelerations, the excitation rate of centripetally accelerated atoms can be $10^{272,878}$ times greater than that of linearly accelerated atoms with the same magnitude of acceleration. Our result suggests that the circular version of the Unruh effect can be significant even at very small centripetal accelerations, contrary to the common belief that a large Unruh effect requires large acceleration. This finding sheds new light on the experimental detection of the circular Unruh effect.

description: Context. Radical chemical reactions on cosmic dust grains play a crucial role in forming various chemical species. Among different radicals, the hydroxyl (OH) is one of the most important ones, with a rather specific chemistry. Aims. The goal of this work is to simulate the recombination dynamics of hydroxyl radicals and the subsequent formation of hydrogen peroxide (H$_{2}$O$_{2}$). Mthods. We employed neural network potentials trained on ONIOM(QM/QM) data, combining multi-reference (CASPT2) and density functional theory (DFT) calculations. This approach allows us to model the recombination of hydroxyl radicals on ice surfaces with high computational efficiency and accuracy. Results. Our simulations reveal that the initial position of the radicals plays a decisive role in determining recombination probability. We found that the formation of hydrogen-bond between radicals, competes with the formation of hydrogen peroxide, reducing the recombination efficiency, contrary to expectancy. This competition reduces the recombination probability for radicals that are initially formed approximately 3 Å apart. Recombination probabilities also depend on the kinetic energy of the added radicals, with values around 0.33 for thermal radicals and a wide range of values between 0.33 and 1.00 for suprathermal OH radicals. Conclusions. Based on our calculations we provide recommendations for introducing OH radical recombination into kinetic astrochemical models, differentiating between thermal and suprathermal radicals. The recombination behavior varies significantly between these two cases: while thermal radicals are sometimes trapped in hydrogen-bonded minima, the case of suprathermal radicals varies with the added energy. Our most important conclusion is that OH radical recombination probability cannot be assumed 1.0 for a wide variety of cases.

Manipulator arm control system for characterizing large-area photosensors
Creators: name: Kugel, Harish
Publisher: name: The University of British Columbia

description: This project is a continuation of a previous ENPH 479 project, completed by Aaron Zimmer and Nils Smit. The original project, for Dr. Hirohisa Tanaka of TRIUMF, sought to characterize the optical properties of a new acrylic shielding used on PMTs employed by the Super-K neutrino observatory. To perform this characterization, a PMT Testing Rig was constructed at TRIUMF. This Testing Rig consists of two robotic manipulator arms, a water tank and a set of Helmholtz coils. It was the task of the previous project team to write control software for the manipulator arms. While they were successful in completing basic control and collision detection, much remained to be finished. Therefore, in order to move the project closer to its objective, this report details improvements to both the Testing Rig and its control software. The improvements proposed for the Testing Rig were moving it to its final location, wiring the limit switches on the rotational axes of the manipulator arms, reducing vibrations by fixing a free-swinging counterweight and cleaning up the wiring. The improvements proposed for the control software were the addition of scan routines to perform Magnetic Field Surveys. Furthermore, additional improvements were requested during the project. These include: constructing cable brackets, wiring all four controllers, wiring the remaining limit switches for X, Y and Z axes, running cables through cable trays and rewriting the initialization routine in feMove. All of the above improvements were successfully completed except for the fixing of the free swinging counter-weight. The methods, equipment used and results for these improvements can be found in the body of the following report. It is the overall recommendation of this report, that work continue as planned.

description: AbstractRecent advances in sensing technologies, particularly Distributed Acoustic Sensing (DAS), have significantly improved the collection and analysis of seismological data. DAS is a powerful method for detecting vibrations from various sources, including earthquakes. However, the vast amount of data produced by DAS requires sophisticated analytical methods to differentiate between signals of interest and noise, such as traffic signals. We introduce an innovative approach by extending the Noise2Self framework to effectively remove unwanted, structured coherent noise from DAS data. By creating masks based on the characteristics of traffic signals, we isolate and preserve earthquake signals while maintaining the denoising performance of the original Noise2Self approach, which reduces noise without requiring clean reference data. To evaluate our method, we used synthetic data generated from seismic recordings of closely spaced seismometers and then applied our approach to data from a DAS array crossing the Alpine Fault near Haast, New Zealand. Our results demonstrate that our model successfully removes traffic noise and other non‐coherent noise while preserving seismic signals, leading to improvements in both Signal‐to‐Noise Ratio (SNR) and waveform coherence. Evaluations on real‐world DAS data further confirm the robustness of our method, positioning it as a valuable tool for analyzing large‐scale DAS data sets in various geoscientific contexts. This approach, which we refer to as “CoherentNoise2Self” to emphasize the extension of Noise2Self to coherent noise, advances the capabilities for near real‐time monitoring and analysis of seismic DAS data.

description: Die Additive Fertigung als „physischer Arm der Digitalisierung“ verbreitet sich zunehmend und wird so zur relevanten Fertigungsalternative im Kontext einer nachhaltigen individualisierten Produktentwicklung. Aufgrund der hohen geometrischen Freiheit lassen sich bionische Strukturen fertigen, Baugruppen in ein einziges Bauteil transformieren, oder ganz allgemein zusätzliche Funktionen integrieren [1, 2]. In Verbindung mit Computer-Aided-Engineering Methoden wie der Topologieoptimierung lassen sich somit Prototypen bereits beinahe vollständig automatisiert entwerfen und fertigen [3]. Ebenso bietet der Einsatz von Füllstrukturen die Möglichkeit das effektive Bauteilverhalten über einen großen Bereich zu variieren und so auch das volle Leichtbaupotential der Technologie auszunutzen [4]. Das tribologische Verhalten additiv gefertigter Strukturen wurde dabei bisher eher als hinderlich wahrgenommen. Dieser Artikel soll aufzeigen, dass durch das Verstehen fertigungsbedingter Effekte neue Perspektiven für die Nutzung der Additiven Fertigung entstehen können.

description: We study the impact of nuclear input related to weak-decay rates and neutron-capture reactions on predictions for the $s$ process in AGB stars. We provide the first database of surface abundances and stellar yields of the isotopes heavier than iron from the $Monash$ models. We run nucleosynthesis calculations with the $Monash$ post-processing code for 7 stellar structure evolution models of low-mass AGB stars with 3 different sets of nuclear input. The reference set has constant decay rates and represents the set used in the previous $Monash$ publications. The second set contains the temperature and density dependence of $β$ decays and electron captures based on the default rates of NETGEN. In the third set, we update 92 neutron-capture rates based on reevaluated experimental cross sections from the ASTRAL. We compare and discuss the predictions of each set relative to each other in terms of isotopic surface abundances and total stellar yields. We also compare results to isotopic ratios measured in presolar stardust SiC grains from AGB stars. The new sets of models resulted in a $\sim$66% solar $s$-process contribution to the $p$-nucleus $\mathrm{^{152}Gd}$, confirming that this isotope is predominantly made by the $s$ process. The nuclear input updates resulted in predictions for the $\mathrm{^{80}Kr/^{82}Kr}$ ratio in the He intershell and surface $\mathrm{^{64}Ni/^{58}Ni}, \mathrm{^{94}Mo/^{96}Mo}$ and $\mathrm{^{137}Ba/^{136}Ba}$ ratios more consistent with the corresponding ratios measured in stardust, however, the new predicted $\mathrm{^{138}Ba/^{136}Ba}$ ratios are higher than the typical values of the stardust SiC grain data. The W isotopic anomalies are in agreement with data from analysis of other meteoritic inclusions. We confirm that the production of $\mathrm{^{176}Lu}$ and $\mathrm{^{205}Pb}$ is affected by too large uncertainties in their decay rates from NETGEN.

description: The resonance mechanism in the initial stage of wind-wave generation proposed by Phillips (J. Fluid Mech., vol. 2, 1957, 417$\unicode{x2013}$445) is a foundation of wind-wave generation theory, but a precise theoretical quantification of wave energy growth in this initial stage has not been obtained yet after more than six decades of research. In this study, we aim to address this knowledge gap by developing an analytical approach based on a novel complex analysis method to theoretically investigate the temporal evolution of the wave energy in the Phillips initial stage. We quantitatively derive and analyse the growth behaviour of the surface wave energy and obtain an analytical solution for its upper bound. Our result highlights the crucial effects of surface tension. Because the phase velocity of gravity$\unicode{x2013}$capillary waves has a minimal value at a critical wavenumber, gravity$\unicode{x2013}$capillary waves and gravity waves (which neglect surface tension) exhibit distinct resonance curve properties and wave energy growth behaviours. For gravity waves, the resonance curve extends indefinitely; for gravity$\unicode{x2013}$capillary waves, it either forms a finite-length curve or does not exist, depending on the wind speed. The leading-order term of the upper-bound solution of the energy of gravity waves increases linearly over time, while for gravity$\unicode{x2013}$capillary waves, the term increases linearly over time under strong wind conditions but remains finite under weak wind conditions. This theoretical study provides an analytical framework for the generation of wind-waves in the Phillips initial stage, which may inspire further theoretical, numerical, and experimental research.

description: In the context of the life cycle and evolution of active galactic nuclei (AGN), the environment plays an important role. In particular, the over-dense environments of galaxy groups, where dynamical interactions and bulk motions have significant impact, offer an excellent but under-explored window into the life cycles of AGN and the processes that shape the evolution of relativistic plasma. Pilot Survey observations with the Australian Square Kilometre Array Pathfinder (ASKAP) Evolutionary Map of the Universe (EMU) survey recovered diffuse emission associated with the nearby (z = 0.0228) galaxy group HCG15, which was revealed to be strongly linearly polarised. We study the properties of this emission in unprecedented detail to settle open questions about its nature and its relation to the group-member galaxies. We perform a multi-frequency spectropolarimetric study of HCG15 incorporating our ASKAP EMU observations as well as new data from MeerKAT, LOFAR, the GMRT, and the Karl G. Jansky Very Large Array (VLA), plus X-ray data from XMM-Newton and optical spectra from the Himalayan Chandra Telescope (HCT). Our study confirms that the diffuse structure represents remnant emission from historic AGN activity, likely associated with HCG15-D, some 80-86 Myr ago (based on ageing analysis). We detect significant highly linearly-polarised emission from a diffuse 'ridge'-like structure with a highly ordered magnetic field. Our analysis suggests that this emission is generated by draping of magnetic field lines in the intra-group medium (IGrM), although further exploration with simulations would aid our understanding. We confirm that HCG15-C is a group-member galaxy. Finally, we report the detection of thermal emission associated with a background cluster at redshift z ~ 0.87 projected onto the IGrM of HCG15, which matches the position and redshift of the recent SZ detection of ACT-CL J0207.8+0209.

Wood veneer applications in surfboard construction : a study of impact resistance
Creators: name: Bissell, Dave
Publisher: name: The University of British Columbia
Year: 2013

description: Surfboards are manufactured with a shaped polyurethane foam core that is wrapped in fiberglass cloth, and sealed with multiple applications of a curing resin product. A graduating project was conducted to find a suitable method to replace the fiberglass with a wood based material, and perform tests to determine the comparable impact resistance qualities of the wood material with the standard fiberglass build method. The wood material selected was a woven veneer mat, made out of 10mm wide strips of Douglas fir veneer. Multiple versions of strip size and mat configurations were considered, with two final mats chosen: a densified, woven, 10mm strip mat, and a non-densified, woven, 10mm strip mat. Samples for testing consisted of a 6” x 6” x 1.25” 3lb/ft³ foam block, a fiber substrate (either a woven veneer mat or fiberglass) and a curing resin (either Polyester or Epoxy), with the fiber substrate bonded to the foam block with the resin. Samples were constructed according to standard surfboard building methods. Samples were tested using an Impact Testing Apparatus, which consisted of a vertically mounted piece of PVC pipe with holes drilled in the side at specific heights, and a plate underneath the pipe on which samples were placed for testing. A 320g steel ball was pushed through the holes in the pipe and dropped onto the face of each sample. Failure was determined to occur when circular cracks appeared in the surface of the sample that could be seen with the naked eye and felt with a bare finger, through which water could access the foam core in a typical surfboard. Samples made with Epoxy resin were approximately 150% stronger than those made with Polyester resin, when averaged across samples of all fiber substrates. Fiberglass samples were on average 115% stronger than woven veneer samples, ranging from a 50% difference between the strongest veneer sample and the weakest fiberglass sample, to 240% between the weakest veneer sample and the strongest fiberglass sample. The strongest sample used a 6oz – 4oz fiberglass combination with Epoxy resin, with the weakest sample using a Densified Woven Veneer mat and Polyester Resin. Densification of wood veneer prior to weaving made construction of the samples easier, as the material was more flexible and easier to weave, but resulted in weaker samples than those made with non-densified veneer. More veneer configurations should be designed and tested to further determine the viability of building a surfboard with wood veneer as opposed to fiberglass.
Resonant drag instabilities for polydisperse dust. II. The streaming and settling instabilities

description: Dust grains embedded in gas flow give rise to a class of hydrodynamic instabilities, called resonant drag instabilities. These instabilities have predominantly been studied for single grain sizes, in which case they are found to grow fast. Nonlinear simulations indicate that strong dust overdensities can form, aiding the formation of planetesimals. In reality, however, there is going to be a distribution of dust sizes, which potentially has important consequences. We study two different resonant drag instabilities, the streaming instability and the settling instability, taking into account a continuous spectrum of grain sizes, to determine whether these instabilities survive in the polydisperse regime and how the resulting growth rates compare to the monodisperse case. We solve the linear equations for a polydisperse fluid in an unstratified shearing box to recover the streaming instability and, for approximate stratification, the settling instability, in all cases focusing on small dust-to-gas ratios. Size distributions of realistic width turn the singular perturbation of the monodisperse limit into a regular perturbation due to the fact that the backreaction on the gas involves an integration over the resonance. The contribution of the resonance to the integral can be negative, as in the case of the streaming instability, which as a result does not survive in the polydisperse regime, or positive, which is the case in the settling instability. The latter therefore has a polydisperse counterpart, with growth rates that can be comparable to the monodisperse case. Wide size distributions in almost all cases remove the resonant nature of drag instabilities. This can lead to reduced growth, as is the case in large parts of parameter space for the settling instability, or complete stabilisation, as is the case for the streaming instability.

description: The Spitzer Survey of Stellar Structure in Galaxies (S$^4$G), together with its Early Type Galaxy (ETG) extension, stand as the most extensive dataset of deep, uniform mid-infrared (mid-IR; 3.6 and 4.5$\,μ$m) imaging for a sample of $2817$ nearby ($d<40 \,$Mpc) galaxies. However, the velocity criterion used to select the original sample results in an additional 422 galaxies without HI detection that ought to have been included in the S$^4$G on the basis of their optical recession velocities. In order to create a complete magnitude-, size- and volume-limited sample of nearby galaxies, we collect $3.6\,μ$m and $i$-band images using archival data from different surveys and complement it with new observations for the missing galaxies. We denote the sample of these additional galaxies as Disc Galaxy (DG) extension. We present the Complete Spitzer Survey of Stellar Structure in Galaxies (CS$^4$G), encompassing a sample of $3239$ galaxies with consistent imaging, surface brightness profiles, photometric parameters, and revised morphological classification. Following the original strategy of the S$^4$G survey, we produce masks, surface brightness profiles, and curves of growth using masked $3.6\,μ$m and $i$-band images. From these profiles, we derive the integrated quantities: total magnitude, stellar mass, concentration parameter, and galaxy size, converting to $3.6\,μ$m. We re-measure these parameters also for the S$^4$G and ETG to create a homogenous sample. We present new morphological revised $T$-types, and we showcase mid-IR scaling relations for the photometric parameters. We complete the S$^4$G sample by incorporating 422 galaxies. The CS$^4$G includes at least 99.94\% of the complete sample of nearby galaxies, meeting the original selection criteria, and it will enable a wide set of investigations into galaxy structure and evolution.
