description: Analyses of the pion valence-quark distribution function (DF), ${u}^π(x;ζ)$, which explicitly incorporate the behaviour of the pion wave function prescribed by quantum chromodynamics (QCD), predict ${u}^π(x\simeq 1;ζ) \sim (1-x)^{β(ζ)}$, $β(ζ\gtrsim m_p)>2$, where $m_p$ is the proton mass. Nevertheless, more than forty years after the first experiment to collect data suitable for extracting the $x\simeq 1$ behaviour of ${u}^π$, the empirical status remains uncertain because some methods used to fit existing data return a result for ${u}^π$ that violates this constraint. Such disagreement entails one of the following conclusions: the analysis concerned is incomplete; not all data being considered are a true expression of qualities intrinsic to the pion; or QCD, as it is currently understood, is not the theory of strong interactions. New, precise data are necessary before a final conclusion is possible. In developing these positions, we exploit a single proposition, viz. there is an effective charge which defines an evolution scheme for parton DFs that is all-orders exact. This proposition has numerous corollaries, which can be used to test the character of any DF, whether fitted or calculated.

description: We demonstrate the use of a fiber-based femtosecond laser locked onto an ultra-stable optical cavity to generate a low-noise microwave reference signal. Comparison with both a liquid Helium cryogenic sapphire oscillator (CSO) and a Ti:Sapphire-based optical frequency comb system exhibit a stability about $3\times10^{-15}$ between 1 s and 10 s. The microwave signal from the fiber system is used to perform Ramsey spectroscopy in a state-of-the-art Cesium fountain clock. The resulting clock system is compared to the CSO and exhibits a stability of $3.5\times10^{-14}τ^{-1/2}$. Our continuously operated fiber-based system therefore demonstrates its potential to replace the CSO for atomic clocks with high stability in both the optical and microwave domain, most particularly for operational primary frequency standards.

description: This is a report about the use and misuse of citation data in the assessment of scientific research. The idea that research assessment must be done using ``simple and objective'' methods is increasingly prevalent today. The ``simple and objective'' methods are broadly interpreted as bibliometrics, that is, citation data and the statistics derived from them. There is a belief that citation statistics are inherently more accurate because they substitute simple numbers for complex judgments, and hence overcome the possible subjectivity of peer review. But this belief is unfounded.

Modeling Molecular Hydrogen and Star Formation in Cosmological Simulations

description: We describe a phenomenological model for molecular hydrogen formation suited for applications in galaxy formation simulations, which includes on-equilibrium formation of molecular hydrogen on dust and approximate treatment of both its self-shielding and shielding by dust from the dissociating UV radiation. The model is applicable in simulations in which individual star forming regions - the giant molecular complexes - can be identified (resolution of tens of pc) and their mean internal density estimated reliably, even if internal structure is not resolved. In agreement with previous studies, calculations based on our model show that the transition from atomic to fully molecular phase depends primarily on the metallicity, which we assume is directly related to the dust abundance, and clumpiness of the interstellar medium. The clumpiness simply boosts the formation rate of molecular hydrogen, while dust serves both as a catalyst of molecular hydrogen formation and as an additional shielding from dissociating UV radiation. The upshot is that it is difficult to form fully-shielded giant molecular clouds while gas metallicity is low. However, once the gas is enriched to Z ~ 0.01-0.1 solar, the subsequent star formation and enrichment can proceed at a much faster rate. This may keep star formation efficiency in the low-mass, low-metallicity progenitors of galaxies very low for a certain period of time with the effect similar to a strong "feedback" mechanism.

description: The vast majority of multi-cellular organisms are anisogamous, meaning that male and female sex cells differ in size. It remains an open question how this asymmetric state evolved, presumably from the symmetric isogamous state where all gametes are roughly the same size (drawn from the same distribution). Here, we use tools from the study of nonlinear dynamical systems to develop a simple mathematical model for this phenomenon. Using theoretical analysis and numerical simulation, we demonstrate that competition between individuals that is linked to the mean gamete size will almost inevitably result in a stable anisogamous equilibrium, and thus isogamy may naturally lead to anisogamy.

description: We measured the ground state electric dipole polarizability of sodium, potassium, and rubidium using a Mach-Zehnder atom interferometer with an electric field gradient. We find alpha_Na=24.11(2)_stat(18)_sys x 10^-24 cm^3, alpha_K=43.06(14)(33), and alpha_Rb=47.24(12)(42). Since these measurements were all performed in the same apparatus and subject to the same systematic errors we can present polarizability ratios with 0.3% precision. We find alpha_Rb/alpha_Na=1.959(5), alpha_K/alpha_Na=1.786(6), and alpha_Rb/alpha_K=1.097(5). We combine our ratio measurements with the higher precision measurement of sodium polarizability by Ekstrom et al. [Phys. Rev. A 51, 3883 (1995)] to find alpha_K=43.06(21) and alpha_Rb=47.24(21).

Vibe Learning: A Future Learning Methodology in the AGI Era
Creators: name: He, Frank
Publisher: name: Zenodo
Year: 2025

description: In the emerging era of Artificial General Intelligence (AGI), **Vibe Learning** is gaining attention as a novel learning methodology. It is a strategy especially relevant to STEM fields (coding, mathematics, physics, engineering) where learners leverage AI to **focus on breadth of understanding over depth of detail**. The term *“vibe”* implies learning by intuition and feel for a subject, rather than exhaustive mastery of every detail. Instead of memorizing formulas or writing every line of code, a learner concentrates on grasping the **big picture** – enough to **prompt an AI effectively** and supervise its output. This report defines Vibe Learning, explores its key principles, compares it with traditional learning, and discusses how it works in practice. We also examine its benefits, risks, and examples of current AI-based learning platforms embodying this approach.
D6.3a – Towards Minilateral Climate Governance? Analysing Climate Club Design Options through the lens of CBDR-RC
Creators: name: Hall, Catherine
Publisher: name: Zenodo
Year: 2024

description: In response to the limitations and failings of the multilateral UN climate change law regime, a range of new and dynamic climate governance arrangements have emerged. This includes minilateral ‘climate clubs’, which enable a subset of countries to tackle climate change beyond the UNFCCC. While proposed as a solution to move international climate policy forward, depending on their specific design, climate clubs could raise implications from the perspective of the principle of common but differentiated responsibilities and respective capabilities (CBDR-RC) that is enshrined in the climate regime. Accordingly, this paper aims to analyse different design options of climate clubs through the lens of CBDR-RC. First, it explains the general rationale for climate clubs and presents a spectrum of key club design features. Second, it conceptualises the principle of CBDR-RC and describes how this has been operationalised. Third, it draws on existing club-like arrangements – namely, the Climate Club launched at COP28, the Clean Energy Ministerial, and the proposed EU-US Global Arrangement on Sustainable Steel and Aluminium – to critically examine whether different design options are (likely to be) compatible with the principle of CBDR-RC. Last, the paper explores how differentiation could be woven into the architecture of future climate clubs.

description: A gravitational wave traversing the line of sight to a distant source produces a frequency shift which contributes to redshift space distortion. As a consequence, gravitational waves are imprinted as density fluctuations in redshift space. The gravitational wave contribution to the redshift space power spectrum. has a different μdependence as compared to the dominant contribution from peculiar velocities. This allows the two signals to be separated. The prospect of a detection is most favourable at the highest observable redshift z. Observations of redshifted 21-cm radiation from neutral hydrogen (HI) hold the possibility of probing very high redshifts. We consider the possibility of detecting primordial gravitational waves using the redshift space HI power spectrum. However, we find that the gravitational wave signal, though present, will not be detectable on super-horizon scales because of cosmic variance and on sub-horizon scales where the signal is highly suppressed.

description: Internet of Bio-Nano Things (IoBNT) is envisioned to be a heterogeneous network of nanoscale and biological devices, so called Bio-Nano Things (BNTs), communicating via non-conventional means, e.g., molecular communications (MC), in non-conventional environments, e.g., inside human body. The main objective of this emerging networking framework is to enable direct and seamless interaction with biological systems for accurate sensing and control of their dynamics in real time. This close interaction between bio and cyber domains with unprecedentedly high spatio-temporal resolution is expected to open up vast opportunities to devise novel applications, especially in healthcare area, such as intrabody continuous health monitoring. There are, however, substantial challenges to be overcome if the enormous potential of the IoBNT is to be realized. These range from developing feasible nanocommunication and energy harvesting techniques for BNTs to handling the big data generated by IoBNT. In this survey, we attempt to provide a comprehensive overview of the IoBNT framework along with its main components and applications. An investigation of key technological challenges is presented together with a detailed review of the state-of-the-art approaches and a discussion of future research directions.

description: We work with combinatorial maps to represent graph embeddings into surfaces up to isotopy. The surface in which the graph is embedded is left implicit in this approach. The constructions herein are proof-relevant and stated with a subset of the language of homotopy type theory. This article presents a refinement of one characterisation of embeddings in the sphere, called spherical maps, of connected and directed multigraphs with discrete node sets. A combinatorial notion of homotopy for walks and the normal form of walks under a reduction relation is introduced. The first characterisation of spherical maps states that a graph can be embedded in the sphere if any pair of walks with the same endpoints are merely walk-homotopic. The refinement of this definition filters out any walk with inner cycles. As we prove in one of the lemmas, if a spherical map is given for a graph with a discrete node set, then any walk in the graph is merely walk-homotopic to a normal form. The proof assistant Agda contributed to formalising the results recorded in this article.

description: High-frequency electron paramagnetic resonance (HFEPR) and AC susceptibility measurements are reported for a new high-symmetry Mn12 complex, [Mn12O12(O2CCH3)16(CH3OH)4].CH3OH. The results are compared with those of other high-symmetry spin S = 10 Mn12 single-molecule magnets (SMMs), including the original acetate, [Mn12(O2CCH3)16(H2O)4].2CH3CO2H.4H2O, and the [Mn12O12(O2CCH2Br)16(H2O)4].4CH2Cl2 & [Mn12O12(O2CCH2But)16(CH3OH)4].CH3OH complexes. These comparisons reveal important insights into the factors that influence the values of the effective barrier to magnetization reversal, Ueff, deduced on the basis of AC susceptibility measurements. In particular, we find that variations in Ueff can be correlated with the degree of disorder in a crystal which can be controlled by desolvating (drying) samples. This highlights the importance of careful sample handling when making measurements on SMM crystals containing volatile lattice solvents. The HFEPR data additionally provide important spectroscopic evidence suggesting that the relatively weak disorder induced by desolvation strongly influences the quantum tunneling interactions, and that it is under-barrier tunneling that is responsible for a consistent reduction in Ueff that is found upon drying samples. Meanwhile, the axial anisotropy deduced from HFEPR is found to be virtually identical for all four Mn12 complexes, with essentially no measurable reduction upon desolvation.

description: Computational methods for fractional differential equations exhibit essential instability. Even a minor modification of the coefficients or other entry data may switch good results to the divergent. The goal of this paper is to suggest the reliable dual approach which fixes this inconsistency. We suggest to use two parallel methods based on the transformation of fractional derivatives through integration by parts or by means of substitution. We introduce the method of substitution and choose the proper discretization scheme that fits the grid points for the by-parts method. The solution is reliable only if both methods produce the same results. As an additional control tool, the Taylor series expansion allows to estimate the approximation errors for fractional derivatives. In order to demonstrate the proposed dual approach, we apply it to linear, quasilinear and semilinear equations and obtain very good precision of the results. The provided examples and counterexamples support the necessity to use the dual approach because either method, used separately, may produce incorrect results. The order of the exactness is close to the exactness of fractional derivatives approximations.

description: We investigate the possibility of contamination by lower-redshift interlopers in the measure of the ionising radiation escaping from high redshift galaxies. Taking advantage of the new ultra-deep VLT/VIMOS U-band number counts in the GOODS-S field,we calculate the expected probability of contamination by low-z interlopers as a function of the U-mag and the image spatial resolution (PSF). Assuming that ground-based observations can not resolve objects lying within a 0.5" radius of each other, then each z>=3 galaxy has a 2.1 and 3.2% chance of foreground contamination, adopting surface density U-band number counts down to 27.5 and 28.5,respectively. Those probabilities increase to 8.5 and 12.6%, assuming 1.0" radius. If applied to the estimates reported in the literature at z~3 for which a Lyman continuum has been observed directly,the probability that at least 1/3 of them are affected by foreground contamination is larger than 50%.From a Monte-Carlo simulation we estimate the median integrated contribution of foreground sources to the Lyman continuum flux (f900). Current estimations from stacked data are >2 sigma of the median integrated pollution by foreground sources.The spatial cross-correlation between the U-band catalog and a sample of galaxies at z>=3.4 in the GOODS-S field,produces a number of U-band detected systems fully consistent with the expected superposition statistics. Indeed, each of them shows the presence of at least one offset contaminant in the ACS images. An exemplary case of a foreground contamination in the HUDF at redshift 3.797 by a foreground blue compact source (U=28.63 +/- 0.2) is reported; if observed with a seeing larger than 0.5" the polluting source would mimic an observed (f1500/f900)_OBS ~ 38, erroneously ascribed to the source at higher redshift.

description: We describe a data structure that maintains the number of triangles in a dynamic undirected graph, subject to insertions and deletions of edges and of degree-zero vertices. More generally it can be used to maintain the number of copies of each possible three-vertex subgraph in time O(h) per update, where h is the h-index of the graph, the maximum number such that the graph contains $h$ vertices of degree at least h. We also show how to maintain the h-index itself, and a collection of h high-degree vertices in the graph, in constant time per update. Our data structure has applications in social network analysis using the exponential random graph model (ERGM); its bound of O(h) time per edge is never worse than the Theta(sqrt m) time per edge necessary to list all triangles in a static graph, and is strictly better for graphs obeying a power law degree distribution. In order to better understand the behavior of the h-index statistic and its implications for the performance of our algorithms, we also study the behavior of the h-index on a set of 136 real-world networks.

A Gricean theory of reference
Creators: name: Beebe, Michael Douglas
Publisher: name: University of British Columbia
Year: 2010

description: I propose to analyse referring, the typical function of proper names and definite descriptions, in terms of speakers' intentions rather than in terms of the meanings of words. Grice's theory of meaning explains how a speaker can mean something simply by making an utterance with the proper sort of intention, and I attempt to apply this theory of meaning to referring. I see two related reasons for thinking a Gricean theory of reference correct. First, I try to show that our speech practice is such as to demand a Gricean-type theory; we simply do depend rather often on hearers' recognition of speakers' intentions to achieve reference. Second, the causal theory of proper names, which I investigate in Chapter 5. seems to demand a Gricean theory of reference. In Chapter 1, I am concerned with whole utterance meaning, and with the problem of going from occasional meaning to conventional meaning. Lewis' analysis of convention is deployed in a way which I think vindicates Grice's hope that conventional or timeless meaning may be analyzed in terms of occasional meaning. In Chapter 2, I attempt to extend the Gricean program to parts of utterances. That is, I argue that an utterance may have meaningful parts and grammatical structure entirely without benefit of convention. Primitive cases of referring and predicating can arise at this pre-conventional level, and here certainly referring is to be explained by a Gricean theory. Chapter 3 contains the body of my argument for a Gricean theory of reference. I try to show that our referring practice is in fact one which depends on the characteristic form of the Gricean intention: the speaker, by his utterance, intends that the hearer shall be affected in some way, intending this to come about at least in part by hearers' recognition of speakers' intentions. The first three section of Chapter 3 are devoted to arguing for the Gricean character of reference, and the remaining two to developing suitable epistemic foundations for such a theory. If a speaker's intention is primary, the meanings of the words he uses are (with qualifications) secondary, so we must be able to explain how a speaker is connected with the object of his reference in some way which does not essentially involve his being able to say something true about that object. I use Kaplan's theory of relational belief, with .its emphasis on the causal element in a belief, to provide this connection. Having a relational belief about an object connects one with it, and allows one to have an intention directed towards it. Chapter ^ is a criticism of the standard theory of reference with Searle and Strawson cast as its defenders. Chapter 5 is a presentation and elaboration of the 'causal' or the 'historical explanation' theory of names, the new theory of names which, I claim, requires a Gricean theory of reference.

description: Hydrothermal carbonization (HTC) is a process that converts biomass into versatile hydrochar without the need for prior drying. The physicochemical properties of hydrochar are influenced by biomass properties and processing parameters, making it challenging to optimize for specific applications through trial-and-error experiments. To save time and money, machine learning can be used to develop a model that characterizes hydrochar produced from different biomass sources under varying reaction processing parameters. Thus, this study aims to develop an inclusive model to characterize hydrochar using a database covering a range of biomass types and reaction processing parameters. The quality and quantity of hydrochar are predicted using two models (decision tree regression and support vector regression). The decision tree regression model outperforms the support vector regression model in terms of forecast accuracy (R2 > 0.88, RMSE < 6.848, and MAE < 4.718). Using an evolutionary algorithm, optimum inputs are identified based on cost functions provided by the selected model to optimize hydrochar for energy production, soil amendment, and pollutant adsorption, resulting in hydrochar yields of 84.31%, 84.91%, and 80.40%, respectively. The feature importance analysis reveals that biomass ash/carbon content and operating temperature are the primary factors affecting hydrochar production in the HTC process.

description: The presence of a critical point in the QCD phase diagram can deform the trajectories describing the evolution of the expanding fireball in the QCD phase diagram. The deformation of the hydrodynamic trajectories will change the transverse velocity dependence of the proton-antiproton ratio when the fireball passes in the vicinity of the critical point. An unusual transverse velocity dependence of the anti-proton/proton ratio in a narrow beam energy window would thus signal the presence of the critical point.

description: A simple fluid, described by point-like particles interacting via the Lennard-Jones potential, is considered under confinement in a slit geometry between two walls at distance Lz apart for densities inside the vapor-liquid coexistence curve. Equilibrium then requires the coexistence of a liquid "bridge" between the two walls, and vapor in the remaining pore volume. We study this equilibrium for several choices of the wall-fluid interaction (corresponding to the full range from complete wetting to complete drying, for a macroscopically thick film), and consider also the kinetics of state changes in such a system. In particular, we study how this equilibrium is established by diffusion processes, when a liquid is inserted into an initially empty capillary (partial or complete evaporation into vacuum), or when the volume available for the vapor phase increases. We compare the diffusion constants describing the rates of these processes in such inhomogeneous systems to the diffusion constants in the corresponding bulk liquid and vapor phases.

description: Co-pyrolysis of biomass feedstocks with polymeric wastes is a promising strategy for improving the quantity and quality parameters of the resulting liquid fuel. Numerous experimental measurements are typically conducted to find the optimal operating conditions. However, performing co-pyrolysis experiments is highly challenging due to the need for costly and lengthy procedures. Machine learning (ML) provides capabilities to cope with such issues by leveraging on existing data. This work aims to introduce an evolutionary ML approach to quantify the (by)products of the biomass-polymer co-pyrolysis process. A comprehensive dataset covering various biomass-polymer mixtures under a broad range of process conditions is compiled from the qualified literature. The database was subjected to statistical analysis and mechanistic discussion. The input features are constructed using an innovative approach to reflect the physics of the process. The constructed features are subjected to principal component analysis to reduce their dimensionality. The obtained scores are introduced into six ML models. Gaussian process regression model tuned by particle swarm optimization algorithm presents better prediction performance (R2 > 0.9, MAE < 0.03, and RMSE < 0.06) than other developed models. The multi-objective particle swarm optimization algorithm successfully finds optimal independent parameters.

description: Research funding and reputation in the UK have, for over two decades, been increasingly dependent on a regular peer-review of all UK departments. This is to move to a system more based on bibliometrics. Assessment exercises of this kind influence the behavior of institutions, departments and individuals, and therefore bibliometrics will have effects beyond simple measurement. [arXiv:0910.3529]

D6.3b – A Race at All Costs? Economic and Environmental Effects of Industrial Policy Nationalism

description: Industrial policy nationalism threatens international collaboration on climate change mitigation. Using regulatory, fiscal, or trade policies to protect and promote the interests of national industries against external competition may increase the cost of transformation and delay the diffusion of key low-carbon technologies. While we need a technology race against climate change, it needs to be a race in a collaborative spirit in which all contestants encourage each other to perform at their best. But a race in the spirit of geopolitical rivalry may cost us the climate.

description: We show that measures of star formation rates (SFRs) for infrared galaxies using either single-band 24 um or extinction-corrected Paschen-alpha luminosities are consistent in the total infrared luminosity = L(TIR) ~ 10^10 L_sun range. MIPS 24 micron photometry can yield star formation rates accurately from this luminosity upward: SFR(M_sun/yr) = 7.8 x 10^-10 L(24 um, L_sun) from L(TIR) = 5 x 10^9 L_sun to 10^11 L_sun, and SFR = 7.8 x 10^-10 L(24 um, L_sun) x (7.76 x 10^-11 L(24))^0.048 for higher L(TIR). For galaxies with L(TIR) >= 10^10 L_sun, these new expressions should provide SFRs to within 0.2 dex. For L(TIR) >= 10^11 L_sun, we find that the SFR of infrared galaxies is significantly underestimated using extinction-corrected Pa-alpha (and presumably using any other optical or near infrared recombination lines). As a part of this work, we constructed spectral energy distribution (SED) templates for eleven luminous and ultraluminous purely star forming infrared galaxies (LIRGs and ULIRGs) and over the spectral range 0.4 microns to 30 cm. We use these templates and the SINGS data to construct average templates from 5 microns to 30 cm for infrared galaxies with L(TIR) = 5 x 10^9 to 10^13 L_sun. All of these templates are made available on line.

Revised in proof to strengthen caveats about the extrapolation of these IR templates above L(TIR)>2e12, without suitable local purely starforming template galaxies above this luminosity.

Il Freemium come modello economico sostenibile per la pubblicazione digitale Open Access nelle scienze umanistiche e sociali

Year: 2013
Subjects: Open Access; humanities; social sciences; freemium; economic models

description: Between the two paths of open access – green and gold – the latter is the harder to develop and has less support from the research community. The main difficulty lies in finding a sound economic model. Open Access journals usually depend on two funding sources: subsidies and/or donations from institutions and publication fees from research units in the author-pay model. These two ways of funding Open Access journals and books have proved effective in some cases (Plos), but are not flawless. The Center for Open Electronic Publishing, a French initiative for Open Access publishing in humanities and social sciences, has recently developed a new economic model based on “Freemium” for its full Open Access journal and book series, in order to address two issues: improve their economic soundness and give them more visibility in libraries. Freemium, a blend of “free” and “premium”, preserves the information side of Open Access as well as premium service marketing.

Il documento sonoro come fonte

description: The sound document as a source

Can sound documents be ‘written’? and can they be ‘read’? The beginnings of the history of sound recording give useful elements to understand these processes and these terms and to clarify their peculiarities. History and music disciplines have considered the role of sound documents as sources, with different ways and in different times. A definition of sound document will be attempted based on the process of sound recording, of which an outline will be given. The document, being an object, is the result of the union of a carrier with a format. The matter of ‘decodification’ of a sound document from a technological point of view will be considered: from here the importance of the technical devices used in the process of reprodution and re-recording. In the end the central topics of originality, authenticity and integrity of sound documents will be considered, taking some examples among the music repertoires without notation: music of the oral tradition, improvised, electroacoustic, phonographic.

description: Accurate estimation of multiple quality variables is critical for building industrial soft sensor models, which have long been confronted with data efficiency and negative transfer issues. Methods sharing backbone parameters among tasks address the data efficiency issue; however, they still fail to mitigate the negative transfer problem. To address this issue, a balanced Mixture-of-Experts (BMoE) is proposed in this work, which consists of a multi-gate mixture of experts (MMoE) module and a task gradient balancing (TGB) module. The MoE module aims to portray task relationships, while the TGB module balances the gradients among tasks dynamically. Both of them cooperate to mitigate the negative transfer problem. Experiments on the typical sulfur recovery unit demonstrate that BMoE models task relationship and balances the training process effectively, and achieves better performance than baseline models significantly.

description: We present the analysis of high-resolution optical spectroscopic observations of the zero-age main-sequence O star Herschel 36 spanning six years. This star is definitely a multiple system, with at least three components detected in its spectrum. Based on our radial-velocity (RV) study, we propose a picture of a close massive binary and a more distant companion, most probably in wide orbit about each other. The orbital solution for the binary, whose components we identify as O9 V and B0.5 V, is characterized by a period of 1.5415 +/- 0.0006 days. With a spectral type O7.5 V, the third body is the most luminous component of the system and also presents RV variations with a period close to 498 days. Some possible hypotheses to explain the variability are briefly addressed and further observations are suggested.

Extensive Quantum Chemistry Study of Neutral and Charged C$_4$N Chains. An Attempt to Aid Astronomical Observation

description: Many molecular species can presumably still be observed in space if they are adequately characterized chemically. In this paper, we suggest that this could be the case of the neutral (C$_4$N$^0$) and anion (C$_4$N$^-$) cyanopropynylidene chains, which were not yet identified in space although both the neutral (C$_3$N$^0$ and C$_5$N$^0$) and anion (C$_3$N$^-$} and C$_5$N$^-$) neighboring members of the homologous series were observed. Extensive data obtained from quantum chemical calculations using density functional theory (DFT), coupled cluster (CC), and quadratic configuration interaction (QCI) methods for all charge and spin states of interest for space science (doublet and quartet neutrals, triplet and singlet anions, and singlet and triplet cations) are reported: e.g., bond metric and natural bond order data, enthalpies of formation, dissociation and reaction energies, spin gaps, rotational constants, vibrational properties, dipole and quadrupole momenta, electron attachment energies ($EA$) and ionization potentials ($IP$). The fact that (not only for C$_4$N but also for C$_2$N and C$_6$N) the quantum chemical methods utilized here are able to excellently reproduce the experimental $EA$ value -- which is often a challenge for theory -- is particularly encouraging, since this indicates that theoretical estimates of chemical reactivity indices (which are key input parameters for modeling astrochemical evolution) can be trusted. The presently calculated enthalpies of formation and dissociation energies do not substantiate any reason to assume that C$_4$N is absent in space. To further support this idea, we analyze potential chemical pathways of formation of both C$_4$N$^0$ and C$_4$N$^-$, which include association and exchange reactions.
