description: Background
Non-target screening of surface water samples collected over an extended period can reveal interesting temporal patterns in exposome-related pollutants. Additionally, geographical data on pollution sources in proximity to the sampling sites, chemical classification data and the consideration of flow paths can provide valuable information on the origins and potential threat of tentatively identified chemical compounds. In this study, 271 surface water samples from 20 sampling sites across Luxembourg were analysed using high resolution mass spectrometry, complementing routine target monitoring efforts in 2019-2022. Data analysis was performed using the open-source R-package patRoon, which offers a customizable non-target workflow. By employing open-source workflows featuring scoring terms, like the individual MoNA score and applying identification levels, tentative identifications can be prioritized, e.g. based on spectral similarity. Furthermore, by utilizing supplementary database information such as PubChemLite categories and classification software such as classyFire, an overall assessment of the potential threats posed by the tentatively identified chemicals was conducted, enabling the prioritization of chemicals for future confirmation through targeted approaches.
Results
The study tentatively identified 375 compounds associated with the exposome including benzenoids, organoheterocyclic compounds, and organic phosphoric acids and derivatives (12 classyFire superclasses, 50 sub-classes). The classification analysis not only revealed temporal variations in agrochemicals, with the majority of identifications occurring in May to July, but also highlighted the prevalence of pharmaceuticals such as venlafaxine in surface waters. Furthermore, the study examined potential sources of pollutants, like metallurgic industry or household products by considering common uses and geographical information, as commercial uses of almost 100% of the identified chemicals are known. 42 chemicals were suggested for potential inclusion to governmental monitoring lists.
Conclusions
The findings of this study complement existing knowledge on the pollution status of surface water in Luxembourg and highlight the usefulness of non-target screening for identifying temporal and spatial trends in pollutant levels. This approach, performed in a complementary manner to routine monitoring, can help to tentatively identify chemicals of concern for inclusion in target monitoring methods following additional confirmation and quantification efforts.

description: Adriamycin (Adr), the single most active agent used in the treatment of breast cancer, may become ineffective as treatment progresses due to the development of multidrug resistant (MDR) tumors. A major mechanism associated with MDR is increased P-glycoprotein (Pgp) expression. This thesis examined the abilities of the antiestrogen tamoxifen (TAM) and the progestin medroxyprogesterone acetate (MPA) as well as cyclosporin A (CsA), a known resistance modifier, to enhance the cytotoxic effects of Adr on human breast epithelial cells (HBEC) in primary culture. Pgp and estrogen receptor (ER) expression were determined in each of the cultures by immunocytochemical assays using the monoclonal antibodies C219 and H222 Spy, respectively. The Adrsensitive, Pgp-, ER+ MCF-7 cell line and the Adr-resistant, Pgp+, ER- MCF7-AdrR cell line were used as controls. Primary cultures were categorized as HBEC from tissues with or without previous chemotherapy. Pgp was detected in 1 of the 15 cell cultures from tissues without previous chemotherapy and in 5 of the 6 cell cultures from tissues previously exposed to chemotherapy. Incubation with either CsA or MPA plus Adr enhanced Adr toxicity in Pgp+ but not Pgp- cell cultures, whereas T AM had no effect on the sensitivity of any of the cultures. Of the 21 primary cultures of HBEC, 3 were ER+. There was no correlation between the enhancement of Adr cytotoxicity and ER status. The data suggest that MPA as well as CsA may be useful as modifying agents in overcoming Pgp-associated multidrug resistance.

description: Recent hydrodynamic simulations and observations of radio jets have shown that the surrounding environment has a large effect on their resulting morphology. To investigate this we use a sample of 50 Extended Radio Active Galactic Nuclei (ERAGN) detected in the Observations of Redshift Evolution in Large Scale Environments (ORELSE) survey. These sources are all successfully cross-identified to galaxies within a redshift range of $0.55 \leq z \leq 1.35$, either through spectroscopic redshifts or accurate photometric redshifts. We find that ERAGN are more compact in high-density environments than those in low-density environments at a significance level of 4.5$σ$. Among a series of internal properties under our scrutiny, only the radio power demonstrates a positive correlation with their spatial extent. After removing the possible radio power effect, the difference of size in low- and high-density environments persists. In the global environment analyses, the majority (86\%) of high-density ERAGN reside in the cluster/group environment. In addition, ERAGN in the cluster/group central regions are preferentially compact with a small scatter in size, compared to those in the cluster/group intermediate regions and fields. In conclusion, our data appear to support the interpretation that the dense intracluster gas in the central regions of galaxy clusters plays a major role in confining the spatial extent of radio jets.
Discussion about a Standard Definition of the Signal-to-Noise Ratio (SNR) for Radio Signals of ultra-high-energy Particles

description: Signal-to-noise ratios are a widely used concept for astroparticle radio detectors, such as air-shower radio arrays for cosmic-ray measurements or detectors searching for radio signals induced by neutrino interactions in ice.
Nonetheless, no common standards or methods are established for the determination of the signal-to-noise ratio: values cannot be compared between experiments, and for the same signal and noise, various methods differ by large factors on the signal-to-noise ratio.
This was the motivation to discuss a community-specific standardization at the ARENA conference 2022.
No agreement on a common method to calculate signal-to-noise ratios was reached, however, awareness was raised that signal-to-noise ratios need to be well defined in any publications.
This includes providing sufficient information on the procedure used to determine the signal-to-noise ratio, in addition to simply stating the formula. Even when using the same definition of the signal-to-noise ratio, there is still a significant dependence on the procedure of calculation, e.g., the signal-to-noise ratio of waveforms containing only background can vary significantly depending on the size of the time interval used as signal search window.
To facilitate the interpretation of any signal-to-noise ratios in a specific study, the recommendation is to also state the mean value of the signal-to-noise ratio that the used method yields when applied to noise used in the study, e.g., the radio background measured by the corresponding experiment.

description: Atomically-resolved mappings of the indium composition in InGaN/GaN multi-quantum wellstructures have been obtained by quantifying the contrast in HAADF-STEM. The quantificationprocedure presented here does not rely on computation-intensive simulations, but rather uses EDXmeasurements to calibrate the HAADF-STEM contrast. The histogram of indium compositionsobtained from the mapping provides unique insights into the growth of InGaN: the transitionfrom GaN to InGaN and vice versa occurs in discreet increments of composition; each incrementcorresponds to one monolayer of the interface, indicating that nucleation takes longer than thelateral growth of the step. Strain-state analysis is also performed by applying Peak-Pair Analysisto the positions of the atomic columns identified the quantification of the contrast. The strainmappings yield an estimate of the composition in good agreement with the one obtained fromquantified HAADF-STEM, albeit with a lower precision. Possible improvements to increase theprecision of the strain mappings are discussed, opening potential pathways for the quantification ofarbitrary quaternary alloys at atomic scales.

description: The author reviews a model for the emission of high energy cosmic rays, gamma-rays and neutrinos from AGN (Active Galactic Nuclei) that he has proposed since 1985. Further discussion of the knee energy phenomenon of the cosmic ray energy spectrum requires the existence of a heavy particle with mass in the knee energy range. A possible method of detecting such a particle in the Pierre Auger Project is suggested. Also presented is a relation between the spectra of neutrinos and gamma-rays emitted from AGN. This relation can be tested by high energy neutrino detectors such as ICECUBE, the Mediterranean Sea Detector and possibly by the Pierre Auger Project.

description: Στην εργασία αυτή προσπαθώ μέσα από την φιλοσοφική σκέψη του τσεχοσλοβάκου φιλόσοφου Karel Kosik να προσεγγίσω δύο έννοιες, οι οποίες κατέχουν κεντρικό ρόλο στις μαρξιστικές αναλύσεις, την έννοια της «πράξης» και του «συγκεκριμένου». Για τον λόγο αυτό στην εργασία κρίνεται, καταρχάς, αναγκαίο να παρουσιαστεί το ιστορικο-φιλοσοφικό πλαίσιο στο οποίο εμφανίζεται η συζήτηση γύρω από τις δύο αυτές έννοιες και να περιγραφούν οι κυριότερες θεματικές που αναπτύχθηκαν την δεκαετία του `50 και του `60, οι οποίες συγκρότησαν το φιλοσοφικό ρεύμα του δυτικού μαρξισμού όπου εντάσσεται και η θεωρία του Kosik. Στο δεύτερο και κύριο μέρος της εργασίας αναπτύσσω τα επιχειρήματα του Kosík όσον αφορά τις δύο παραπάνω έννοιες και επιχειρώ να αναδείξω την στοχαστική του πορεία, η οποία, μέσα από την κριτική επαναπροσέγγιση γνωστών μαρξιστικών όρων από μια φαινομενολογική σκοπιά, καταλήγει στην δική του ερμηνευτική αποσαφήνιση των παραπάνω εννοιών. Συγκεκριμένα, η ανάλυση ξεκινά, κατά περίπτωση, από τις αφετηριακές προσεγγίσεις του Kosík όσον αφορά π.χ. τα σχεσιακά ζεύγη «θεωρία-πράξη», «ελευθερία – αναγκαιότητα», «εργασία-οικονομία» αλλά και τις έννοιες «οικονομικός άνθρωπος», «φροντίδα», «ολότητα» κ.α. Η προβληματική στην οποία εμπλέκεται ο Kosik οδηγεί, τελικά, στην πρόταση του για μια «πρακτική ελευθερία», ως φιλοσοφική και πολιτική θέση έναντι κάθε μορφής καταπίεσης και υποβιβασμού του ανθρώπου και ταυτόχρονα αναδεικνύει τον ιστορικό ρόλο ενός ανθρωπιστικού μαρξισμού.
description: In this paper I try to approach through the philosophical thought of the Czechoslovak philosopher Karel Kosik two concepts which play central role in marxist analysis those of “praxis” and “concrete”. For this reason it is necessary to present the historical and philosophical context in which appears the discussion about these two concepts. It is also significant to describe the main themes developed in the `50`s and` 60`s, which formed the philosophical currents of western marxism to which Kosik also belongs. In the second and main part of the paper I develop Kosík`s arguments regarding these two concepts and I attempt to show the stochastic dialectical pathway, which through the critical reappraisal of several known marxist terms from a phenomenological perspective, leads to his own interpretive clarification of these two concepts. Specifically, the analysis begins from the baseline theoretical approaches of Kosík on the relational pairs “theory-practice” “freedom – nessecity”, “labor-economy” and the concepts of “homo oeconomicus”, “care”, “totality”, etc. Kosik`s problematic finally leads to his proposal for a “practical freedom” as a philosophical and political position against all forms of oppression and relegation of man, which also highlights the historical role of a humanist marxism.

description: Selective manipulation of spin states in iron(II) complexes by thermal or photonic energy is a desirable goal in the context of developing molecular functional materials. As dynamic spin-state equilibration in isolated iron(II) complexes typically limits the lifetime of a given spin state to nanoseconds, synthetic strategies need to be developed that aim at inhibited relaxation. Herein we show that modulation of the reaction coordinate through careful selection of the ligand can indeed massively slow down dynamic exchange. Detailed structural analysis of [FeL]2+ and [ZnL]2+ (L: tris(1-methyl-2-{[pyridin-2-yl]-methylene}hydrazinyl)phosphane sulfide) with crystallographic and computational methods clearly reveals a unique trigonal-directing effect of the extended-tripod ligand L during spin crossover, which superimposes the ubiquitous [FeN6] breathing with trigonal torsion, akin to the archetypal Bailar twist. As a consequence of the diverging reaction coordinates in [FeL]2+ and in the tren-derived complex [Fe(tren)py3]2+, their thermal barriers differ massively, although the spin crossover energies are close to identical. As is shown by time-resolved transient spectroscopy and dynamic 1H-NMR line broadening, reference systems deriving from tren (tris-(2-aminoethyl)amine), which greatly lack such trigonal torsion, harbor very rapid spin-state exchange.

A developmental analysis of habituation in C. elegans
Creators: name: Gannon, Timothy Neil
Publisher: name: University of British Columbia

description: C. elegans is particularly well-suited for a developmental analysis of learning and memory. A developmental analysis of learning attempts to establish relationships between the emergence of particular forms of learning and memory, and the emergence of specific neural structures and circuits, and C. elegans’ ontogeny is extremely well-characterized, including the complete developmental lineage of each somatic cell. Previous developmental research found that whereas the adult and young adult worms almost always reversed and swam backwards to tap, the larval worms only reversed about one-half of the time, and accelerated forwards the other half of the time. This response heterogeneity is a serious problem, because accelerations and reversals are two qualitatively different behavioral outcomes that cannot be easily compared. One solution to this problem is to laser ablate the PLM sensory neurons (which results in a worm that only reverses to tap) in one experiment, and ablate the ALM sensory neurons (which results in a worm that only accelerates forward in response to tap) in a second experiment so that in each experiment there is a single, homogeneous response type that can be compared across and within groups. The focus of this thesis was to study the effect of repeated stimulation on accelerations and reversals in ablated worms across development. Habituation training was given to PLM-ablated and ALM-ablated animals at each of the 6 developmental stages (LI, L2, L3, L4, young adult, 4 day old adult), and at each of 2 ISIs (10 second and 60 second) using the tap-withdrawal paradigm. The results showed that habituation and recovery from habituation were both present in C. elegans at all stages, both ISIs, and both response types. There was also surprisingly little systematic variation in the characteristics of habituation and recovery over development, which further suggests that the basic neural machinery underlying this behavioral plasticity is present and functional as early as the LI stage. These experiments represent the first systematic and quantitative investigation of learning and memory in C. elegans over the course of its development.

description: This paper presents science potential of a deep ocean antineutrino observatory under development at Hawaii. The observatory design allows for relocation from one site to another. Positioning the observatory some 60 km distant from a nuclear reactor complex enables precision measurement of neutrino mixing parameters, leading to a determination of neutrino mass hierarchy. At a mid-Pacific location the observatory measures the flux and ratio of uranium and thorium decay neutrinos from earth's mantle and performs a sensitive search for a hypothetical natural fission reactor in earth's core. A subsequent deployment at another mid-ocean location would test lateral heterogeneity of uranium and thorium in earth's mantle.

description: We have performed X-ray powder diffraction, magnetization, electrical resistivity, heat capacity and inelastic neutron scattering (INS) to investigate the physical properties of the intermetallic series of compounds CeCuBi$_{2-x}$Sb$_{x}$. These compounds crystallize in a tetragonal structure with space group $P4/nmm$ and present antiferromagnetic transition temperatures ranging from 3.6 K to 16 K. Remarkably, the magnetization easy axis changes along the series, which is closely related to the variations of the tetragonal crystalline electric field (CEF) parameters. This evolution was analyzed using a mean field model, which included anisotropic nearest-neighbor interactions and the tetragonal CEF Hamiltonian. The CEF parameters were obtained by fitting the magnetic susceptibility data with the constraints given by the INS measurements. Finally, we discuss how this CEF evolution can affect the Kondo physics and the search for a superconducting state in this family.

description: Modern internet of things (IoT) devices leverage machine learning inference using sensed data on-device rather than offloading them to the cloud. Commonly known as inference at-the-edge, this gives many benefits to the users, including personalization and security. However, such applications demand high energy efficiency and robustness. In this paper we propose a method for reduced area and power overhead of self-timed early-propagative asynchronous inference circuits, designed using the principles of learning automata. Due to natural resilience to timing as well as logic underpinning, the circuits are tolerant to variations in environment and supply voltage whilst enabling the lowest possible latency. Our method is exemplified through an inference datapath for a low power machine learning application. The circuit builds on the Tsetlin machine algorithm further enhancing its energy efficiency. Average latency of the proposed circuit is reduced by 10x compared with the synchronous implementation whilst maintaining similar area. Robustness of the proposed circuit is proven through post-synthesis simulation with 0.25 V to 1.2 V supply. Functional correctness is maintained and latency scales with gate delay as voltage is decreased.

description: Aiming to describe the wealth distribution evolution, several models consider an ensemble of interacting economic agents that exchange wealth in binary fashion. Intriguingly, models that consider an unbiased market, that gives to each agent the same chances to win in the game, are always out of equilibrium until the perfect inequality of the final state is attained. Here we present a rigorous analytical demonstration that any system driven by unbiased binary exchanges are doomed to drive the system to perfect inequality and zero mobility.

Detection of young ($\leq$20 Myr) stellar populations in apparently quenched low-mass galaxies using red spectral line indices

description: We report on the detection of a small contribution (around and below 1% in mass) from young stellar components with ages $\leq$20 Myr in low-mass galaxies purposely selected from the MaNGA survey to be already-quenched systems. Among the sample of 28 galaxies, eight of them show signatures of having suffered a very recent burst of star formation. The detection has been done through the analysis of line-strength indices in the red spectral range [5700,8800] Å. The increasing contribution of red supergiants to this red regime is responsible for a deviation of the index measurements with respect to their position within the model grids in the standard spectral range [3600,5700] Å. We demonstrate that a combination of red indices, as well as a qualitative assessment of the mean luminosity-weighted underlying stellar population, is required in order to distinguish between a true superyoung population and other possible causes of this deviation, such as abundance ratio variations. Our result implies that many presumably quenched low-mass galaxies actually contain gas that is triggering some level of star formation. They have, therefore, either accreted external gas, internally recycled enough gas from stellar evolution to trigger new star formation, or they kept a gas reservoir after the harassment or stripping process that quenched them in first place. Internal processes are favoured since we find no particular trends between our non-quenched galaxies and their environment, although more work is needed to fully discard an external influence.

description: We discuss the use of a hysteretic Josephson junction to detect current fluctuations with frequencies below the plasma frequency of the junction. These adiabatic fluctuations are probed by switching measurements observing the noise-affected average rate of macroscopic quantum tunneling of the detector junction out of its zero-voltage state. In a proposed experimental scheme, frequencies of the noise are limited by an on-chip filtering circuit. The third cumulant of current fluctuations at the detector is related to an asymmetry of the switching rates.

Sinodalità: ascoltare e discernere

Publisher: name: Apulia Theologica
Year: 2025

description: Il tema dell’articolo è la sinodalità nel suo processo di ascolto, discernimento e attuazione
di quanto lo Spirito suggerisce alla Chiesa, perché meglio conosca se stessa e apra un
cammino verso nuovi orizzonti nella verità e nel dialogo reciproco. Il testo è strutturato
in due parti seguite da diverse conclusioni. La prima parte fornisce una premessa circa
il fondamento trinitario dell’identità ecclesiale cristiana; la seconda parte offre un approfondimento
sull’«ascolto e il discernimento».
Nell’immediatezza dell’Eucaristia, dove la Chiesa sperimenta il Regno in anticipo,
l’opera
salvifica di Cristo continua nell’obbedienza della fede stessa della Chiesa; infatti,
la Chiesa stessa si realizza accogliendo l’azione dello Spirito Santo nella Chiesa
manifestata nell’Eucaristia.
Solo ricevendo la presenza attiva dello Spirito Santo la Chiesa può concordare e decidere
«all’unanimità» (vescovi, presbiteri e tutti i fedeli) e «armoniosamente» (con un
unico sentimento).
La koinonia diventa così lo spazio entro il quale si dischiude la sinodalità, entro il
quale le strutture ecclesiali sono intese come riflesso della vita e dell’amore trinitari.
Le conclusioni dimostrano che un’ecclesiologia di comunione e sinodalità deve, quindi,
essere alimentata da una teologia che ponga in dialogo fecondo cristologia e pneumatologia.
Quanto riconosciuto necessario sarà inizio di una fondata revisione «sinodale» del CIC.

description: No abstracts are to be cited without prior reference to the author. Microscopic plastic debris is emerging as a global conservation issue. Ingestion of microplastics has been demonstrated in a range of marine animals both in the laboratory and in the oceans, but we know little of how microplastics may be transferred across trophic levels. Here, we used mussels (Mytilus edulis) and crabs (Carcinus maenas) to investigate the bioaccumulation and trophic transfer of 10μm fluorescently labelled polystyrene microspheres. Organisms were exposed to microplastics through trophic transfer (oral ingestion) or direct exposure (via the ventilation process) and internal distribution, gut transit and depuration were studied using dissection and fluorescence microscopy. Our results show that microplastics were rapidly distributed across body tissues and provide gut transit times in our trophic model and through uptake across the gill in our ventilation model. We will present an update of our results and discuss their wider ecological implications.

description: A superconducting single-electron transistor (SSET) coupled to an anharmonic oscillator, e.g., a Josephson junction-L-C circuit, can drive the latter to a nonequilibrium photon number state. By biasing the SSET in a regime where the current is carried by a combination of inelastic quasiparticle tunneling and coherent Cooper-pair tunneling (Josephson quasiparticle cycle), cooling of the oscillator as well as a laser like enhancement of the photon number can be achieved. Here we show, that the cut-off in the quasiparticle tunneling rate due to the superconducting gap, in combination with the anharmonicity of the oscillator, may create strongly squeezed photon number distributions. For low dissipation in the oscillator nearly pure Fock states can be produced.

description: The Quasi-Biennial Oscillation (QBO) of stratospheric winds is the most striking example of mean-flow generation and reversal by the non-linear interactions of internal waves. Previous studies have used an idealized monochromatic forcing to investigate the QBO. Here we instead force a more realistic continuous wave spectrum. Unexpectedly, spreading the wave energy across a wide frequency range leads to more regular oscillations. We also find that different forcing spectra can yield the same QBO. Multi-modal wave forcing is thus essential for understanding wave/mean-flow interactions in nature.

Life without bounds: does the game of life exhibit self-organized criticality in the thermodynamic limit?
Creators: name: Blok, Hendrik Jan
Publisher: name: University of British Columbia
Year: 2009

description: Recently, a class of phenomena known as self-organized criticality (SOC) has been discovered. SOC is characterized by two properties: firstly, the system exhibits power law behavior typical of a critical state, with no characteristic time or length scales; and secondly, this state is approached naturally, without tuning any external parameters. Early studies explained SOC in terms of conserved quantities [1,2]. Then Bak et al. [3] suggested that the Game of Life, GL, a cellular automaton lacking any conserved quantities, also exhibited SOC. This sparked a debate as to whether GL truly is SOC; conflicting data suggested it was subcritical [4,5,6]. In this paper I explore both sides of the argument in an attempt to resolve the issue. By finding an explicit form for the scaling function the opposing arguments are reconciled and, with some slight reservations, GL is judged to be subcritical. The differences between the analysis herein and other studies is highlighted. I also introduce the reader to some other interesting features of GL, and cellular automata in general, in order to elicit the proper respect for these simple yet complex models. In doing so I hope to impress upon the reader the insufficiencies of the available analytical tools. New methods are required to account for the long-range correlations which develop in GL and other deterministic automata.

description: The recent discovery of graphene has sparked significant interest, which has so far been focused on the peculiar electronic structure of this material, in which charge carriers mimic massless relativistic particle. However, the structure of graphene - a single layer of carbon atoms densely packed in a honeycomb crystal lattice - is also puzzling. On the one hand, graphene appears to be a strictly two-dimensional (2D) material and exhibits such a high crystal quality that electrons can travel submicron distances without scattering. On the other hand, perfect 2D crystals cannot exist in the free state, according to both theory and experiment. This is often reconciled by the fact that all graphene structures studied so far were an integral part of larger 3D structures, either supported by a bulk substrate or embedded in a 3D matrix. Here we report individual graphene sheets freely suspended on a microfabricated scaffold in vacuum or air. These membranes are only one atom thick and still display a long-range crystalline order. However, our studies by transmission electron microscopy (TEM) have revealed that suspended graphene sheets are not perfectly flat but exhibit intrinsic microscopic roughening such that the surface normal varies by several degrees and out-of-plane deformations reach 1 nm. The atomically-thin single-crystal membranes offer an ample scope for fundamental research and new technologies whereas the observed corrugations in the third dimension may shed light on subtle reasons behind the stability of 2D crystals.

description: New solutions of relativistic wave equations are obtained in a unified manner from generating functions of spinorial variables. The choice of generating functions as Gaussians leads to representations in the form of generalized fractional Fourier transforms. Wave functions satisfying the Dirac, Maxwell, and Weyl equations are constructed by simple differentiations with respect to spinorial arguments. In the simplest case, one obtains Maxwell and Dirac hopfion solutions.

description: No abstracts are to be cited without prior reference to the author. Small plastic detritus, or microplastics, are a widespread and ubiquitous contaminant of marine ecosystems. Despite the vital ecological role of zooplankton in the marine food web, the impact of microplastics on zooplankton is under-researched. Our recent work has demonstrated that a range of zooplankton taxa can ingest polystyrene microplastics (7–31 µm in diameter). Further, feeding experiments have indicated that microplastic exposure significantly decreases algal feeding in copepods and this may have health impacts (i.e. reduced growth and fecundity). We have further observed that microplastics are egested by zooplankton within faecal pellets. Here we present data demonstrating that the incorporation of low-density microplastics within faecal pellets reduces their sinking rate and structural integrity. Reduced sinking velocity increases the opportunities for coprophagy and coprorhexy, and reduces the likelihood of the pellet reaching the benthos.

description: We study phase ordering on networks and we establish a relation between the exponent $a_χ$ of the aging part of the integrated autoresponse function $χ_{ag}$ and the topology of the underlying structures. We show that $a_χ>0$ in full generality on networks which are above the lower critical dimension $d_L$, i.e. where the corresponding statistical model has a phase transition at finite temperature. For discrete symmetry models on finite ramified structures with $T_c = 0$, which are at the lower critical dimension $d_L$, we show that $a_χ$ is expected to vanish. We provide numerical results for the physically interesting case of the $2-d$ percolation cluster at or above the percolation threshold, i.e. at or above $d_L$, and for other networks, showing that the value of $a_χ$ changes according to our hypothesis. For $O({\cal N})$ models we find that the same picture holds in the large-${\cal N}$ limit and that $a_χ$ only depends on the spectral dimension of the network.
