description: We look at solutions (both BPS and non-BPS) of the $\mathbb{CP}^{N-1}$ model on $\mathbb{R} \times S^1$ (with twisted boundary conditions), in particular by using a conformal mapping technique, and we show how to interpret these solutions by decomposing them into expressions describing constituent solitons. We point out the problems that may arise (for non-BPS solutions) when one naively looks at the clustering properties of these solutions. This could lead to misunderstandings when studying extrapolations between small and large compactification radii.

description: We compute the Nicolai map for the supersymmetric Yang-Mills theory, in the light-cone gauge, to the second order in the coupling constant for all critical dimensions (d=3,4,6,10). The process of integrating out unphysical degrees of freedom in this gauge, produces a four fermion interaction term. We show that, to the order investigated here, this term is harmless. We demonstrate the existence of a particularly `simple' map in d=4 in the light-cone gauge and address the issue of uniqueness in the context of the map. We also investigate the map in the light-cone superspace in d=4.

description: Utilizing the electron orbital degree of freedom in heterostructures is attracting increasing attention due to the possibility of achieving much larger conversion rates between charge and orbital angular momentum flow compared to the intrinsic electron spin. Here, we consider orbital angular momentum currents in a tight-binding multiorbital lattice model and derive their continuity equation. From it, we observe that the current is not conserved and apply similar considerations to the recently discovered altermagnets. We find nonzero orbital torque terms, elucidate their physical mechanism, and show numerically that they contribute to dampening the orbital angular momentum current flowing in multiorbital heterostructures. Moreover, we compute the orbital RKKY interaction and find it exhibits similar characteristics as the orbital angular momentum current mediating it, thus serving as a direct experimental probe of such currents.

description: The force distribution of jammed disordered packings has always been considered a central object in the physics of granular materials. However, many of its features are poorly understood. In particular, analytic relations to other key macroscopic properties of jammed matter, such as the contact network and its coordination number, are still lacking. Here we develop a mean-field theory for this problem, based on the consideration of the contact network as a random graph where the force transmission becomes a constraint optimization problem. We can thus use the cavity method developed in the last decades within the statistical physics of spin glasses and hard computer science problems. This method allows us to compute the force distribution $\text P(f)$ for random packings of hard particles of any shape, with or without friction. We find a new signature of jamming in the small force behavior $\text P(f) \sim f^θ$, whose exponent has attracted recent active interest: we find a finite value for $\text P(f=0)$, along with $θ=0$. Furthermore, we relate the force distribution to a lower bound of the average coordination number $\, {\bar z}_{\rm c}^{\rm min}(μ)$ of jammed packings of frictional spheres with coefficient $μ$. This bridges the gap between the two known isostatic limits $\, {\bar z}_{\rm c}(μ=0)=2D$ (in dimension $D$) and $\, {\bar z}_{\rm c}(μ\to \infty)=D+1$ by extending the naive Maxwell's counting argument to frictional spheres. The theoretical framework describes different types of systems, such as non-spherical objects in arbitrary dimensions, providing a common mean-field scenario to investigate force transmission, contact networks and coordination numbers of jammed disordered packings.

description: Passive acoustic monitoring is a reliable method to study species behaviour and ecology, enabling the discovery of species activity patterns, especially in remote locations. Here, we conducted a year-long recording study to describe annual and circadian patterns in the vocal activity of two African barbet species, the Yellow-rumped Tinkerbird Pogoniulus bilineatus and the Western Tinkerbird Pogoniulus coryphaea. We used automated software to detect vocalisations of the two species from 4893 one-hour recordings taken in Cameroon. In total, we obtained 31,526 vocalisations of Yellow-rumped Tinkerbirds and 1318 vocalisations of Western Tinkerbirds. We used generalised additive mixed models to determine whether the month or hour of recording or meteorological conditions influenced the species’ vocal activity. Our results indicated that both tinkerbirds are likely seasonal breeders, as the highest vocal activity of both species was during the dry season. Both species exhibited smaller activity peaks in the wet season. Our study provides new information on the vocal activity patterns of two barbet species, which could be valuable in future monitoring and surveying efforts. This study provides an illustrative example of two useful technologies that facilitate studies in remote areas: passive acoustic monitoring for determining species’ activity patterns and automatic recognition software for the rapid analysis of large datasets.
title: Origin and genesis of the Goldenville iron formations and implications for mineralization, Baie Verte, Newfoundland, Canada
Creators: name: Mueller, Carly
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: The Goldenville iron formation (IF) and associated sedimentary rocks, within the Point Rousse complex of the Baie Verte Peninsula, hosts the Goldenville Au deposit and produced 23 tonnes of ore between 1904-1906 (158 oz gold recovered). The Goldenville IF marks the end of Cambrian-Ordovician (~489-485 Ma) Au-rich VMS activity (i.e., VMS Rambler-Ming district), is considered to be correlative with the Nugget Pond IF with both iron formations believed to form a marker unit between the Mount Misery Formation and the overlying Snooks Arm Group cover sequence (~470 Ma), and captures paleo-oceanic redox conditions during the transition from the Cambrian to Ordovician. Despite economic, stratigraphic, and geological importance of the Goldenville IF, it has received very little textural-mineralogical-geochemical study. The Goldenville horizon is a laterally discontinuous, fine-grained, and laminated unit within argillites, volcaniclastic rocks, and basalt flows. Chemostratigraphy provides evidence of multiple iron formation horizons between the Mount Misery Formation and the overlying Snooks Arm Group cover sequence. In particular, the position of the Goldenville iron formation is lower in stratigraphy and contained within the Mount Misery Formation. In the IF, the lithogeochemical data reflect varying contributions from detrital material, hydrothermal discharge, and hydrogenous elements scavenged from seawater. Samples with the highest hydrothermally sourced Fe and Mn abundance preserve evidence in their REE+Y chemistry for two distinct oxide particle scavenging shuttles that operated in a volcanically active basin with oxygenated bottom waters. Textural evidence of gold in and proximal to the IF suggests that hydrothermal fluids interacted with Fe³⁺-bearing minerals within the IF, resulting in wall rock sulfidation and the co-precipitation of gold and pyrite.

Signatures of electron-magnon interaction in charge and spin currents in magnetic tunnel junctions: A nonequilibrium many-body perturbation theory approach

description: We develop a numerically exact scheme for resumming certain classes of Feynman diagrams in the self-consistent perturbation expansion for the electron and magnon self-energies in the nonequilibrium Green function formalism applied to a coupled electron-magnon (\mbox{e-m}) system which is driven out of equilibrium by the applied finite bias voltage. Our scheme operates with the electronic and magnonic GFs and the corresponding self-energies viewed as matrices in the Keldysh space, rather than conventionally extracting their retarded and lesser components. This is employed to understand the effect of inelastic \mbox{e-m} scattering on charge and spin current vs. bias voltage $V_b$ in F/I/F magnetic tunnel junctions (MTJs), which are modeled on a one-dimensional (1D) tight-binding lattice for the electronic subsystem and 1D Heisenberg model for the magnonic subsystem. For this purpose, we evaluate Fock diagram for the electronic self-energy and the electron-hole polarization bubble diagram for the magnonic self-energy. The respective electronic and magnonic GF lines within these diagrams are the fully interacting ones, thereby requiring to solve the ensuing coupled system of nonlinear integral equations self-consistently. Despite using the 1D model and treating \mbox{e-m} interaction in many-body fashion only within a small active region consisting of few lattice sites around the F/I interface, our analysis captures essential features of the so-called zero-bias anomaly observed in both MgO- and AlO$_x$-based realistic 3D MTJs where the second derivative $d^2 I/dV_b^2$ (i.e., inelastic electron tunneling spectrum) of charge current exhibits sharp peaks of opposite sign on either side of the zero bias voltage.

It describes the entire fusing matrix for both NS and R sector of N=1 supersymmetric Liouville field theory. In the NS sector, our formula is related to an expression derived in [1]. Through analytic continuation in the spin variables, our universal expression reproduces known formulas for the Racah-Wigner coefficients of finite dimensional representations.

description: Polymer matrices, when placed in contact with a fluid phase made of low molecular weight compounds, undergo a depression of their glass transition temperature (Tg) determined by the absorption of these compounds and the associated plasticization phenomena. Frequently, this effect is coupled with the mechanical action of the compressive stress exerted by the pressure of the fluid phase that, in contrast, promotes an increase in the Tg. This issue is relevant for technological and structural applications of composites with high-performance glassy polymer matrices, due to their significant impact on mechanical properties. We propose an approach to model and predict rubbery-glassy states maps of polymer–penetrant mixtures as a function of pressure and temperature based on the Gibbs–Di Marzio criterion. This criterion establishes that a ‘thermodynamic’ glass transition does occur when the configurational entropy of the system vanishes. Although questioned and criticized, this criterion constitutes a good practical approach to analyse changes of Tg and, in some way, reflects the idea of an ‘entropy catastrophe’ occurring at the glass transition. Several polymer–penetrant systems have been analysed modelling configurational entropy by means of the Non-Random Hydrogen Bond lattice fluid theory, able to cope with possible non-random mixing and occurrence of strong interactions.This article is part of the theme issue 'Ageing and durability of composite materials'.

description: After the accident in the Japanese Fukushima Dai-ichi nuclear power plant in March 2011 large amounts of radioactivity were released and distributed in the atmosphere. Among them were also radioactive noble gas isotopes which can be used as tracers to test global atmospheric circulation models. This work presents unique measurements of the radionuclide $^{133}$Xe from Fukushima in the upper troposphere above Germany. The measurements involve air sampling in a research jet aircraft followed by chromatographic xenon extraction and ultra-low background gas counting with miniaturized proportional counters. With this technique a detection limit of the order of 100 $^{133}$Xe atoms in litre-scale air samples (corresponding to about 100 mBq/m$^3$) is achievable. Our results provide proof that the $^{133}$Xe-rich ground level air layer from Fukushima was lifted up to the tropopause and distributed hemispherically. Moreover, comparisons with ground level air measurements indicate that the arrival of the radioactive plume at high altitude over Germany occurred several days before the ground level plume.

description: Little Corellas (Cacatua sanguinea) are notorious for damaging crops and ornamental trees, and are an overabundant nuisance native in some urban areas. Habitat and landscape use studies ideally require the attachment of tracking devices. Here, we describe an attempt to attach GPS transmitters to Little Corellas using the backpack and keel-strap harness method. All five tracking devices initially attached to Little Corellas were removed by the birds within 48-hours. Additionally, a conspecific was observed chewing on the Teflon ribbon of a GPS harness shortly after the release of a Little Corella; a novel record that suggests cooperative abilities for the species. To complement our study, we conducted a literature review of parrot (psittacine) tracking studies. We investigated attachment styles and potential reasons for past device removals. Of the 46-relevant studies, neck collars were the most common attachment method (38.8%), followed by backpack harnesses (24.5%). Transmitter removal was documented in 28.3% of studies, with removals being most common for medium-sized (500–1000 g) species, and for combination (simultaneous back- and tail-mounts; n = 4) and backpack harness attachments (n = 6). Although there are relatively few parrot telemetry studies to date, they are increasing, and future studies will require considerable innovation and collaboration to overcome attachment style hurdles for difficult species, like the Little Corella.

description: Cold dark matter halos form within a smoothly distributed background of relic neutrinos -- at least some of which are massive and non-relativistic at late times. We calculate the accumulation of massive neutrinos around spherically collapsing cold dark matter halos in a cosmological background. We identify the physical extent of the "neutrino halo" in the spherical collapse model, which is large in comparison with the virial radius of the dark matter, and conditions under which neutrinos reaching the cold dark matter halo will remain bound to the halo at late times. We calculate the total neutrino mass and bound neutrino mass associated with isolated spherical halos for several neutrino mass hierarchies and provide fitting formulae for these quantities in terms of the cold dark matter halo mass and the masses of the individual neutrino species.

description: Social discrimination is used as a territorial cost-mitigation behaviour across several taxonomic groups. However, whether this phenomenon is similar across populations or varies due to local ecological traits remains an open field. Here, we tested whether social discrimination ability exhibited by pairs of Rufous Horneros (Furnarius rufus) varies between two spatially distinct Brazilian populations (Brasília and Juiz de Fora), with contrasting population densities. We predicted that Rufous Horneros would show the highest aggression towards strangers’ duets in the low-density population (the ‘dear enemy effect’), and towards neighbours’ duets in the high-density population (the ‘nasty neighbour effect’). We also examined the impact of territorial centrality (distance to the centre of the conspecific neighbourhood) on territorial responses, assuming that territorial harassment varies with centrality. We observed a consistent dear enemy effect expression (i.e. lower response to simulated intrusions by neighbours compared to strangers) across both populations, despite their differing densities. Additionally, we found no effect of territorial centrality on playback responses. Our findings show that the dear enemy effect is widely distributed in Rufous Horneros, at least in the breeding season, being observed even in a high-density population. Our findings also highlight the lack of advantages for central territories. Future studies should investigate whether territorial mitigation strategies exhibit consistency across different contexts and taxa.

description: We reconsider the gauge hierarchy problem from the viewpoint of effective field theories and a high-energy physics, motivated by the alternative scenario that the standard model holds up to a high-energy scale such as the Planck scale. The problem is restated as the question whether it is possible to construct a low-energy effective theory and the interaction with heavy particles, without spoiling the structure of a high-energy physics supported by an excellent concept. Based on this reinterpretation, we give a conjecture that theories with hidden fermionic symmetries can be free from the gauge hierarchy problem and become candidates of the physics beyond and/or behind the standard model, and present toy models with particle-ghost symmetries as illustrative examples and a prototype model for the grand unification.

Publisher: name: Old Dominion University Libraries

description: Asian Americans represent both the fastest-growing population and the smallest group of consumers of mental health services (MHS) in the United States. The current study aimed to identify factors associated with MHS use and explore differences in MHS use by nativity among Asian Americans. Data from the 2015-2018 National Health and Nutrition Examination Survey (NHANES) were used to examine past-year MHS use among Asian Americans ages 18 and older. Weighted analyses were used to determine the distribution of the population by nativity and other covariates, and Rao-Scott Chi-Square tests were used to explore the association between past-year MHS use and these predictors of interest. Multiple logistic regression was used to examine the association between nativity and past-year use of mental health services while controlling for other covariates. Of the 1476 respondents, only 4.54%, 95% CI [3.60%, 5.45%] reported using MHS in the past year. After controlling for other factors, nativity was significantly associated with past-year MHS use, with individuals born outside of the US being 0.42, 95% CI [0.18, 0.98] times less likely to use MHS than those born in the US. Additionally, past-year MHS use was significantly associated with factors such as marital status, general health condition, having a routine source of care, and depression severity. Our findings suggest that nativity and other factors may impact access to and utilization of mental health services among Asian Americans. Future research may aim to improve MHS utilization in this population through mental health education or the development of culturally sensitive treatment.

description: We implement a highly efficient strong-coupling expansion for the Green's function of the Hubbard model. In the limit of extreme correlations, where the onsite interaction is infinite, the evaluation of diagrams simplifies dramatically enabling us to carry out the expansion to the eighth order in powers of the hopping amplitude. We compute the finite-temperature Green's function analytically in the momentum and Matsubara frequency space as a function of the electron density. Employing Pade approximations, we study the equation of state, Kelvin thermopower, momentum distribution function, quasiparticle fraction, and quasiparticle lifetime of the system at temperatures lower than, or of the order of, the hopping amplitude. We also discuss several different approaches for obtaining the spectral functions through analytic continuation of the imaginary frequency Green's function, and show results for the system near half filling. We benchmark our results for the equation of state against those obtained from a numerical linked-cluster expansion carried out to the eleventh order.

Der gemeinwohlorientierte Einsatz von Softwarelösungen, basierend auf algorithmischen Systemen und Künstlicher Intelligenz (KI), wird von vielen in der Freien Wohlfahrtspflege als Chance gesehen. Aktuell fehlt es jedoch häufig noch an Anwendungsideen und Umsetzungskompetenz. Diese Studie arbeitet heraus, wie das Konzept eines Tech-Fellowships für die Wohlfahrt beide Aspekte adressieren kann: zum einen die Potenziale algorithmischer Systeme für die Arbeit und Herausforderungen der Wohlfahrt zu heben und zum anderen die Mitarbeitenden durch Praxisanwendungen zu befähigen, kompetent und kritisch mit den Systemen umzugehen.

Das Tech-Fellowship ist demnach ein Programm, in dem Herausforderungen in den Arbeitsfeldern der Freien Wohlfahrtspflege mithilfe algorithmenbasierter Softwareprodukte bedarfsorientiert adressiert werden. Die Studie analysiert den Status quo der Digitalisierungsprozesse der Verbände sowie die Auseinandersetzung mit Algorithmen und KI, um dann Bedingungen für ein erfolgreiches Fellowship abzuleiten.

Mit dem Konzept eines „Tech-Fellowship für die Wohlfahrt“ haben wir ein Instrument ausgearbeitet, das wir in den nächsten Monaten zusammen mit Partner:innen pilotieren möchten. Ein solches Fellowship braucht tatkräftige Unterstützung aus vielen Bereichen. Daher: Melden Sie sich gerne bei uns, wenn Sie Interesse an der Umsetzung haben, genauso wie an einer Teilnahme. Wir veröffentlichen diese Studie bereits vor der Pilotierung, weil wir einen offenen Lernprozess fördern und auch gerne Resonanz, konstruktive Kritik sowie Unterstützer:innen in den weiteren Prozess einbinden möchten.

title: “The philosophy of moving on: the benefits of therapeutic philosophy on becoming self in the face of suffering heartbreak”
Creators: name: Katz, Elana
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: This work will consider the therapeutic benefits of philosophy and practical ethics in curing the ills of the soul, and particularly in curing the heartbreak and grief over lost love. I will consider three philosophical models which I take to be medico-therapeutic and candidates for developing a philosophy of moving on: Stoicism, Spinozism, and a contemporary love ethic presented by bell hooks and Erich Fromm. These three models will point to acting in accordance with one’s nature as the remedy for suffering, what I will call “becoming oneself,” or moving on. While each model has therapeutic methods and tools to contribute to a philosophical therapy of moving on, I will find the love model offers the most ideal methodology, since moving on is encouraged at all times as being a necessary aspect of loving behaviour, or living by a love ethic. In addition, I will find that Stoic therapy, in advising the extirpation of the affections, fails to capitalize on affection’s ability to increase our knowledge of ourselves. Conversely, Spinoza and hooks will defend affection in therapeutic philosophy and prove its relevance to self-help.

description: Degenerate quantum gases of alkaline-earth-like elements open new opportunities in research areas ranging from molecular physics to the study of strongly correlated systems. These experiments exploit the rich electronic structure of these elements, which is markedly different from the one of other species for which quantum degeneracy has been attained. Specifically, alkaline-earth-like atoms, such as strontium, feature metastable triplet states, narrow intercombination lines, and a non-magnetic, closed-shell ground state. This review covers the creation of quantum degenerate gases of strontium and the first experiments performed with this new system. It focuses on laser-cooling and evaporation schemes, which enable the creation of Bose-Einstein condensates and degenerate Fermi gases of all strontium isotopes, and shows how they are used for the investigation of optical Feshbach resonances, the study of degenerate gases loaded into an optical lattice, as well as the coherent creation of Sr_2 molecules.

description: The distribution of the resources needed by females for reproduction affects their dispersion in space and time, which in turn influences the number of females a male can defend. When males provide parental care they in turn become a resource for females, and influence where females choose to breed. Combined, these factors explain a preponderance of monogamous and (to a lesser extent) polygynous mating systems in birds. However, less frequently observed mating systems in birds remain harder to explain. Here, we analyse the home ranges of male Eclectus parrots (Eclectus roratus) to investigate how their use of space facilitates an unusual polygynandrous mating system (where multiple males mate with multiple females). Female Eclectus parrots in the rainforests of northern Queensland, Australia, have limited movements. They remain at their nest trees for most of the year and rely on multiple wide-ranging males to bring them their food. We used light aircraft and VHF transmitters to track the movements of four male Eclectus parrots during the breeding season. We combined data on home range size with molecular analyses of a larger sample of breeding birds. Our analyses demonstrate that male home ranges overlap with each other and encompass multiple (3–14) trees with nesting females. We show that some males divide their time between, and gain reproductive success with, females up to 7 km apart. Our tracking and molecular data offer insights into how polygynandrous mating systems relate to space use among males and females.

description: It is likely that nearly all central galactic massive and supermassive black holes are nonradiative: their accretion luminosities are orders of magnitude below what can be explained by efficient black hole accretion within their ambient environments. These objects, of which Sagittarius A* is the best-known example, are also dilute (mildly collisional to highly collisionless) and optically thin. In order for accretion to occur, magnetohydrodynamic instabilities must develop that not only transport angular momentum, but also gravitational energy generated through matter infall, outwards. A class of new magnetohydrodynamical fluid instabilities -- the magnetoviscous-thermal instability (MVTI) (Islam12) -- was found to transport angular momentum and energy along magnetic field lines through large (fluid) viscosities and thermal conductivities. This paper describes the collisionless and mildly collisional analogue to the MVTI, the collisional magnetothermal instability (CMTI), that similarly transports energy and angular momentum outwards, expected to be important in describing the flow properties of hot, dilute, and radiatively inefficient accretion flows around black holes. In this paper we derive a form of the collisionless drift-kinetic equation appropriate for accretion physics. We construct a local equilibrium for MHD stability analysis in this differentially rotating disk. We then find and characterize specific instabilities expected to be important in describing the flow properties of hot, dilute, and radiatively inefficient accretion flows around black holes, and show their qualitative similarities to instabilities derived using a fluid formalism (Islam12). We conclude with further work needed in modeling this class of accretion flow.

Wave packet dynamics and zitterbewegung of heavy holes in a quantizing magnetic field

description: In this work we study wave packet dynamics and $zitterbewegung$, an oscillatory quantum motion, of heavy holes in III-V semiconductor quantum wells in presence of a quantizing magnetic field. It is revealed that a Gaussian wave-packet describing a heavy hole diffuses asymmetrically along the circular orbit while performing cyclotron motion. The wave packet splits into two peaks with unequal amplitudes after a certain time depending on spin-orbit coupling constant. This unequal splitting of the wave packet is attributed to the cubic Rashba interaction for heavy holes. The difference in the peak amplitudes disappears with time. At a certain time the two peaks diffuse almost along the entire cyclotron orbit. Then tail and head of the diffused wave packet interfere and as a result a completely randomized pattern of the wave packet is observed. The diffusion rate of the wave packet increases with increase of the spin-orbit interaction strength. Also strong spin-orbit coupling expedite the splitting and the randomization of the wave packet. We also study the $zitterbewegung$ in various physical observables such as position, charge current and spin angular momentum of the heavy hole. The $zitterbewegung$ oscillations are very much sensitive to the initial wave vector of the Gaussian wave packet and the strength of the Rashba spin-orbit coupling.

Phases of non-extremal multi-centered bound states

description: We investigate the phase space of multi-centered near-extremal configurations previously studied in arXiv:1108.5821 and arXiv:1110.5641 in the probe limit. We confirm that in general the energetically favored ground state of the multi-center potential, which can be a single or multi-center configuration, has the most entropy and is thus thermodynamically stable. However, we find the surprising result that for a subset of configurations, even though a single center black hole seems to be energetically favored, it is entropically not allowed (the resulting black hole would violate cosmic censorship). This disproves classical intuition that everything would just fall into the black hole if energetically favored. Along the way we highlight a shortcoming in the literature regarding the computation of the angular momentum coming from electromagnetic interaction in the probe limit and rectify it. We also demonstrate that static supertubes can exist inside ergoregions where ordinary point particles would be frame dragged.

description: Monte Carlo simulations are widely employed to measure the physical properties of glass-forming liquids in thermal equilibrium. Combined with local Monte Carlo moves, the Metropolis algorithm can also be used to simulate the relaxation dynamics, thus offering an efficient alternative to molecular dynamics. Monte Carlo simulations are however more versatile, because carefully designed Monte Carlo algorithms can more efficiently sample the rugged free energy landscape characteristic of glassy systems. After a brief overview of Monte Carlo studies of glass-formers, we define and implement a series of Monte Carlo algorithms in a three-dimensional model of polydisperse hard spheres. We show that the standard local Metropolis algorithm is the slowest, and that implementing collective moves or breaking detailed balance enhances the efficiency of the Monte Carlo sampling. We use time correlation functions to provide a microscopic interpretation of these observations. Seventy years after its invention, the Monte Carlo method remains the most efficient and versatile tool to compute low-temperatures properties in supercooled liquids.

Warm dark matter does not do better than cold dark matter in solving small-scale inconsistencies

description: Over the last decade, warm dark matter (WDM) has been repeatedly proposed as an alternative scenario to the standard cold dark matter (CDM) one, potentially resolving several disagreements between the CDM model and observations on small scales. Here, we reconsider the most important CDM small-scale discrepancies in the light of recent observational constraints on WDM. As a result, we find that a conventional thermal (or thermal-like) WDM cosmology with a particle mass in agreement with Lyman-$α$ is nearly indistinguishable from CDM on the relevant scales and therefore fails to alleviate any of the small-scale problems. The reason for this failure is that the power spectrum of conventional WDM falls off too rapidly. To maintain WDM as a significantly different alternative to CDM, more evolved production mechanisms leading to multiple dark matter components or a gradually decreasing small-scale power spectrum have to be considered.
