description: As a free, intensive, rarely interactive and well directional messenger, solar neutrinos have been driving both solar physics and neutrino physics developments for more than half a century. Since more extensive and advanced neutrino experiments are under construction, being planned or proposed, we are striving toward an era of precise and comprehensive measurement of solar neutrinos in the next decades. In this article, we review recent theoretical and experimental progress achieved in solar neutrino physics. We present not only an introduction to neutrinos from the standard solar model and the standard flavor evolution, but also a compilation of a variety of new physics that could affect and hence be probed by solar neutrinos. After reviewing the latest techniques and issues involved in the measurement of solar neutrino spectra and background reduction, we provide our anticipation on the physics gains from the new generation of neutrino experiments.

description: Photoexcited quasiparticle relaxation dynamics in overdoped Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+δ}$ ($T_{c}$=65~K, hole doping $p$=0.22) single crystal is investigated as a function of temperature. We provide evidence of a $\sim$22~meV pseudogap ($T^{\ast}$$\approx$100~K) at this doping level. Our data support the scenario where both the superconducting gap and pseudogap coexist in the superconducting state. Our results also suggest an increased scattering rate between electrons and spin fluctuations as the sample enters the pseudogap phase.

Mixed Mediation of Supersymmetry Breaking with Anomalous U(1) Gauge Symmetry

description: Models with anomalous U(1) gauge symmetry contain various superfields which can have nonzero supersymmetry breaking auxiliary components providing the origin of soft terms in the visible sector, e.g. the U(1) vector superfield, the modulus or dilaton superfield implementing the Green-Schwarz anomaly cancellation mechanism, U(1)-charged but standard model singlet matter superfield required to cancel the Fayet-Iliopoulos term, and finally the supergravity multiplet. We examine the relative strength between these supersymmetry breaking components in a simple class of models, and find that various different mixed mediations of supersymmetry breaking, involving the modulus, gauge, anomaly and D-term mediations, can be realized depending upon the characteristics of D-flat directions and how those D-flat directions are stabilized with a vanishing cosmological constant. We identify two parameters which represent such properties and thus characterize how the various mediations are mixed. We also discuss the moduli stabilization and soft terms in a variant of KKLT scenario, in which the visible sector Kähler modulus is stabilized by the D-term potential of anomalous U(1) gauge symmetry.

description: The 511 keV positron annihilation emission remains a mysterious component of the high energy emission of our Galaxy. Its study was one of the key scientific objective of the SPI spectrometer on-board the INTEGRAL satellite. In fact, a lot of observing time has been dedicated to the Galactic disk with a particular emphasis on the central region. A crucial issue in such an analysis concerns the reduction technique used to treat this huge quantity of data, and more particularly the background modeling. Our method, after validation through a variety of tests, is based on detector pattern determination per ~6 month periods, together with a normalisation variable on a few hour timescale. The Galactic bulge is detected at a level of ~70 sigma allowing more detailed investigations. The main result is that the bulge morphology can be modelled with two axisymmetric Gaussians of 3.2 deg. and 11.8 deg. FWHM and respective fluxes of 2.5 and 5.4 x 10^-4 photons/(cm^2.s^1). We found a possible shift of the bulge centre towards negative longitude at l=-0.6 +/- 0.2 degrees. In addition to the bulge, a more extended structure is detected significantly with flux ranging from 1.7 to 2.9 x10^-3 photons/(cm^2.s^1) depending on its assumed geometry (pure disk or disk plus halo). The disk emission is also found to be symmetric within the limits of the statistical errors.

description: Efforts to utilize growing volumes of clinical imaging data to generate tumor evaluations continue to require significant manual data wrangling owing to the data heterogeneity. Here, we propose an artificial intelligence-based solution for the aggregation and processing of multisequence neuro-oncology MRI data to extract quantitative tumor measurements. Our end-to-end framework i) classifies MRI sequences using an ensemble classifier, ii) preprocesses the data in a reproducible manner, iii) delineates tumor tissue subtypes using convolutional neural networks, and iv) extracts diverse radiomic features. Moreover, it is robust to missing sequences and adopts an expert-in-the-loop approach, where the segmentation results may be manually refined by radiologists. Following the implementation of the framework in Docker containers, it was applied to two retrospective glioma datasets collected from the Washington University School of Medicine (WUSM; n = 384) and the M.D. Anderson Cancer Center (MDA; n = 30) comprising preoperative MRI scans from patients with pathologically confirmed gliomas. The scan-type classifier yielded an accuracy of over 99%, correctly identifying sequences from 380/384 and 30/30 sessions from the WUSM and MDA datasets, respectively. Segmentation performance was quantified using the Dice Similarity Coefficient between the predicted and expert-refined tumor masks. Mean Dice scores were 0.882 ($\pm$0.244) and 0.977 ($\pm$0.04) for whole tumor segmentation for WUSM and MDA, respectively. This streamlined framework automatically curated, processed, and segmented raw MRI data of patients with varying grades of gliomas, enabling the curation of large-scale neuro-oncology datasets and demonstrating a high potential for integration as an assistive tool in clinical practice.
Geophysical constraint on a relic background of the dilatons

description: According to a scenario in string cosmology, a relic background of light dilatons can be a significant component of the dark matter in the Universe. A new approach of searching for such a dilatonic background by observing Earth's surface gravity was proposed in my previous work. In this paper, the concept of the geophysical search is briefly reviewed, and the geophysical constraint on the dilaton background is presented as a function of the strength of the dilaton coupling, $q_b^2$. For simplicity, I focus on massless dilatons and assume a simple Earth model. With the current upper limit on $q_b^2$, we obtain the upper limit on the dimensionless energy density of the massless background, $Ω_{DW}h^2_{100} \leq 6 \times 10^{-7}$, which is about one-order of magnitude more stringent than the one from astrophysical observations, at the frequency of $\sim$ 7 $\times$ 10$^{-5}$ Hz. If the magnitude of $q_b^2$ is experimentally found to be smaller than the current upper limit by one order of magnitude, the geophysical upper limit on $Ω_{DW}h^2_{100}$ becomes less stringent and comparable to the one obtained from the astrophysical observations.

description: We explore the imaginary-time relaxation dynamics near quantum critical points with semi-ordered initial states. Different from the case with homogeneous ordered initial states, in which the order parameter $M$ decays homogeneously as $M\propto τ^{-β/νz}$, here $M$ depends on the location $x$, showing rich scaling behaviors. Similar to the classical relaxation dynamics with an initial domain wall in Model A, which describes the purely dissipative dynamics, here as the imaginary time evolves, the domain wall expands into an interfacial region with growing size. In the interfacial region, the local order parameter decays as $M\propto τ^{-β_1/νz}$, with $β_1$ being an additional dynamic critical exponent. Far away from the interfacial region the local order parameter decays as $M\propto τ^{-β/νz}$ in the short-time stage, then crosses over to the scaling behavior of $M\propto τ^{-β_1/νz}$ when the location $x$ is absorbed in the interfacial region. A full scaling form characterizing these scaling properties is developed. The quantum Ising model in both one and two dimensions are taken as examples to verify the scaling theory. In addition, we find that for the quantum Ising model the scaling function is an analytical function and $β_1$ is not an independent exponent.

description: In this article we investigate the influence of nuclear effects in the production of gluinos in nuclear collisions at the LHC, and estimate the transverse momentum dependence of the nuclear ratios $R_{pA} = {\frac{dσ(pA)}{dy d^2 p_T}} / A {\frac{dσ(pp)}{dy d^2 p_T}}$ and $R_{AA} = {\frac{dσ(AA)}{dy d^2 p_T}} / A^2 {\frac{dσ(pp)}{dy d^2 p_T}}$. We demonstrate that depending on the magnitude of the nuclear effects, the production of gluinos could be enhanced, compared to proton-proton collisions. The study of these observables can be useful to determine the magnitude of the shadowing and antishadowing effects in the nuclear gluon distribution. Moreover, we test different SPS scenarios, corresponding to different soft SUSY breaking mechanisms, and find that the nuclear ratios are strongly dependent on that choice.

description: The 2-m aperture Chinese Space Station Telescope (CSST), which observes at wavelengths ranging from 255 to 1000 nm, is expected to start science operations in 2024. An ultra-deep field observation program covering approximately 10 square degrees is proposed with supernovae (SNe) and other transients as one of its primary science drivers. This paper presents the simulated detection results of type Ia supernovae (SNe Ia) and explores the impact of new datasets on the determinations of cosmological parameters. The simulated observations are conducted with an exposure time of 150 s and cadences of 10, 20, and 30 days. The survey mode covering a total of 80 observations but with a random cadence in the range of 4 to 14 days is also explored. Our simulation results indicate that the CSST can detect up to $\sim 1800$ SNe Ia at z $<$ 1.3. The simulated SNe Ia are then used to constrain the cosmological parameters. The constraint on $Ω_m$ can be improved by 37.5% using the 10-day cadence sample in comparison with the Pantheon sample. A deeper measurement simulation with a 300 s exposure time together with the Pantheon sample improves the current constraints on $Ω_m$ by 58.3% and $ω$ by 47.7%. Taking future ground-based SNe Ia surveys into consideration, the constraints on $ω$ can be improved by 59.1%. The CSST ultra-deep field observation program is expected to discover large amounts of SNe Ia over a broad redshift span and enhance our understanding of the nature of dark energy.

Structure-function relationship of uridine diphosphate glucuronosyltransferases (UGTs)
Creators: name: Liu, Yuejian
Publisher: name: University of British Columbia
Year: 2021

description: PURPOSE Uridine diphosphate glucuronosyltransferases (UGTs) are Phase II conjugation enzymes that are critical for vertebrate detoxication. They catalyze the glucuronidation biotransformations of numerous endo- and xenobiotics to facilitate their clearance and elimination and are important for hormonal regulation. Glucuronidation-related disorders include congenital syndromes, excessive chemical toxicities, adverse drug reactions, and dysregulated hormonal status. Since the 1980s it has been known that UGT proteins can be expressed but not fully active, yet little is known about how the UGT protein structure regulates its activity and function, because of the lack of a complete structure. We hypothesized that translational and post-translational mechanisms may play a role in regulating the activity and function of human UGTs. Aim 1 and 2 focused on UGT isoform 1A6, one of the most important isoforms in endo- and xenobiotic metabolism. Aim 3 studied the co-expression of major human hepatic UGT isoforms to gain an insight on their co-regulation in vivo. METHODS N-glycosylation variants of human UGT1A6 were established to study the influence of N-glycosylation on their expression, activity, cellular function and localization. HEK293 expressed UGT1A6-(His)6 and Sf9-insect expressed soluble UGT1A6 were purified and their activity and latency were characterized. The co-expression between 7 UGTs was investigated based on a western blot database collected from healthy liver donors, aged fetal (20 weeks) – 87 years. GENERAL CONCLUSIONS N-glycosylation is an important regulator of human UGT1A6 in expression, activity, and cellular function. Different forms of N-glycosylation were observed for UGT1A6 between HEK293 cells and human liver microsomes, showing a caveat of using recombinant cell lines to study UGT structure/function. Sf9-insect expressed soluble UGT1A6 is a good candidate for structure analysis due to sufficient yield and activity after purification. The influence of membranes on UGTs may be different from traditional beliefs as the data suggested alamethicin and Brij 58 can directly activate the enzyme. Lastly, expression of major human hepatic UGTs was significantly correlated and correlations were affected by age. The UGTs may be co-regulated in the human liver so single-isoform systems may have limitations on reflecting UGT activity in vivo.

Vi saranno delle considerazioni sui vari problemi che causano il successo della maggior parte degli attacchi informatici e ci saranno delle idee sul come è possibile prevenire sempre più questi problemi grazie all’uso delle nuove tecnologie, come il Machine Learning e gli XDR, o anche senza l’uso della tecnologia in generale. Verranno messe in pratica due di queste idee, con la creazione di tre distinti programmi che verranno integrati con il sistema di prevenzione XDR. Un programma è un’estensione per il web browser Firefox che, grazie a servizi di terze parti, controlla i siti dove si naviga e blocca la connessione se si tenta di entrare in siti malevoli. In caso di visita di siti web malevoli verrà avvisato il servizio XDR tramite un’applicazione creata appositamente, il quale avviserà poi il team di sicurezza. La seconda soluzione, suddiviso in due, è un Antimalware che analizza tutti i dischi installati nel sistema operativo trovando tutti i file con estensione .exe e .dll. Grazie a dei dati pubblici, verrà utilizzata la tecnica del Machine Learning, tecnica alla base delle intelligenze artificiali, la quale analizzerà se i file trovati sono dei possibili malware oppure no. Se lo fossero, verranno inviati al server centrale dove il secondo programma utilizzerà il programma Ghidra, utilizzato per decomporre i file e leggerne il codice sorgente, per estrarre delle informazioni quali IP, URL e altro. Queste informazioni verranno poi controllate per verificare se il file è effettivamente un malware oppure no. In caso di positività, verrà avvisato il server Wazuh e la squadra che si occupa della sicurezza informatica.

description: Η τουριστική ανάπτυξη που έχει σημειωθεί τα τελευταία χρόνια στα Χανιά, έχει ως αποτέλεσμα ολοένα και περισσότεροι ιδιοκτήτες να μετατρέπουν τις κατοικίες τους σε χώρους φιλοξενίας. Αυτό έχει ως συνέπεια, πολλοί άνθρωποι κυρίως νέοι(φοιτητές, νεαρά ζευγάρια, νέες οικογένειες, κ.α.) να αντιμετωπίζουν πρόβλημα εύρεσης κατοικίας. Παράλληλα, καθώς η πόλη είναι ήδη αρκετά δομημένη δεν διαθέτει πολλές οικοδομήσιμες εκτάσεις εντός του ιστού της.
Παρατηρείται ωστόσο, ότι σε αρκετά σημεία της πόλης υπάρχουν κτήρια κτισμένα σε πολύ μικρής έκτασης οικόπεδα, τα οποία είτε έχουν εγκαταλειφθεί είτε βρίσκονται σε κακή κατάσταση, χωρίς να έχουν αξιοποιηθεί μέχρι τώρα. Θα μπορούσε λοιπόν, σε περίπτωση που δεν είναι διατηρητέα, να γίνει καθαίρεση και στη θέση τους να σχεδιαστούν νέες κατοικίες  αμβλύνοντας έτσι το οικιστικό πρόβλημα.
Πιο συγκεκριμένα, στην παρούσα εργασία προτείνεται η δημιουργία τυποποιημένων συγκροτημάτων ελάχιστης κατοίκησης. Το σύστημα της ελάχιστης κατοίκησης γενικότερα  δεν έχει εφαρμοστεί ξανά σε μία πόλη όπως τα Χανιά. Η εφαρμογή του ωστόσο, θα μπορούσε να αξιοποιήσει καλύτερα τα μικρής έκτασης οικοδομήσιμα κενά, καθώς μπορεί να δημιουργηθεί ένας μεγαλύτερος αριθμός  κατοικιών σε μικρό χρονικό διάστημα και  χωρίς ουσιαστικά να αλλάξει το χωρικό αποτύπωμα της πόλης.
Στην περιοχή του Κουμ Καπί, εντοπίστηκαν αρκετά κτήρια όπως περιγράφονται παραπάνω, όποτε και επιλέχθηκε ένα τμήμα του προς μελέτη.
Τα συγκροτήματα θα αποτελούνται από δύο διαφορετικούς τύπους ελάχιστης κατοίκησης και θα απευθύνονται κυρίως σε νέους και σε οικογένειες. Οι κατοικίες αυτές θα έχουν ως κύρια χαρακτηριστικά την ευελιξία, την προσαρμοστικότητα και την  πολλαπλότητα των χρήσεων. Θα υπάρχει δηλαδή η δυνατότητα δημιουργίας διαφορετικών χώρων  ανάλογα με τις ανάγκες που καλούνται κάθε φορά να ικανοποιήσουν.
Η δημιουργία των παραπάνω συγκροτημάτων στα μικρά οικοδομήσιμα κενά του αστικού ιστού , θα μπορούσε να επιλύσει σε ένα μεγάλο βαθμό το πρόβλημα της στέγασης και θα λειτουργούσε αναζωογονητικά για την πόλη.

description: AI-mediated communication is designed to help us do our work more quickly and efficiently. But does it come at a cost? This study uses smart replies (SRs) to show how AI influences humans without any intent on the part of the developer - the very use of AI is sufficient. I propose a loss of agency theory as a viable approach for studying the impact of AI on human agency. This theory focusses on the transfer of agency that is forced by circumstances (such as time pressure), human weaknesses (such as complacency), and conceptual priming. Mixed methods involving a crowdsourced experiment test that theory. The quantitative results reveal that machine agency affects the content we author and the behavior we generate. But it is a non-zero-sum game. The transfers between human and machine agency are fluid; they complement, replace, and reinforce each other at the same time.

description: In order to study the origin of high-frequency quasi-periodic oscillations observed in X-ray binaries, Kato (2004) suggested a resonant excitation mechanism of disk oscillations in deformed disks. In this paper, we study numerically, following his formulation, whether trapped g-mode oscillations in a warped disk, where the warp amplitude varies with radius, can be excited by this mechanism. For simplicity, we adopt Newtonian hydrodynamic equations with relativistic expressions for the characteristic frequencies of disks. We also assume that the accretion disk is isothermal. We find that the fundamental modes of trapped g-mode oscillations with eigenfrequencies close to the maximum of epycyclic frequency are excited. The intermediate oscillations found are isolated in a narrow region around the resonance radius. After varying some parameters, we find that the growth rate increases as the warp amplitude or the black hole spin parameter increases, while it decreases as the sound speed increases.

description: Questo lavoro di diploma si orienta verso la ricerca bibliografica basandosi su alcuni modelli di coinvolgimento famigliare e visando uno degli elementi importanti nel percorso educativo dei bambini che è il rapporto scuola-famiglia. L’argomento in questione ha prodotto studi che si concentrano sempre più sulla comprensione e importanza del ruolo dei genitori nell’interazione con il processo di insegnamento-apprendimento svolto nella e dalla scuola. Verranno sollevati alcuni aspetti positivi e negativi del rapporto scuola-famiglia, per provare a chiarire quanto sia rilevante questo dialogo per lo sviluppo dei bambini. Questo mio lavoro di ricerca mi ha permesso di concludere che la scuola ha il ruolo non solo di insegnare i contenuti scolastici ma anche di socializzare promuovendo la relazione e l’alleanza con i genitori nell’interesse dello sviluppo educativo dei loro figli/nostri allievi.

description: We have performed spin- and angle-resolved photoemission spectroscopy of Bi2Te3 and present the first direct evidence for the existence of the out-of-plane spin component on the surface state of a topological insulator. We found that the magnitude of the out-of-plane spin polarization on a hexagonally deformed Fermi surface (FS) of Bi2Te3 reaches maximally 25% of the in-plane counterpart while such a sizable out-of-plane spin component does not exist in the more circular FS of TlBiSe2, indicating that the hexagonal deformation of the FS is responsible for the deviation from the ideal helical spin texture. The observed out-of-plane polarization is much smaller than that expected from existing theory, suggesting that an additional ingredient is necessary for correctly understanding the surface spin polarization in Bi2Te3.

Physiological mechanisms facilitating morphological plasticity across hydrodynamic gradients in kelps
Creators: name: Coleman, Liam James Marshall
Publisher: name: University of British Columbia

description: Some kelp species exhibit morphological plasticity across gradients of hydrodynamic forcing. Such kelps tend to grow narrow, flat blades in fast flow and broad, undulate blades in slow flow. This plasticity is an adaptive phenomenon that allows the kelps that show it to continuously reduce drag while enhancing productivity. While the functional consequences of this phenomenon have been relatively well studied, the developmental mechanisms that underlie it are poorly understood. The primary goal of this thesis is to improve our understanding of the developmental processes facilitating morphological plasticity across hydrodynamic gradients in kelps. I first conducted several experiments where I applied tension to blade tissue of the kelp Nereocystis luetkeana in various ways to better characterize the growth response to mechanical stimulation normally imposed by drag. The results of these experiments suggest that plasticity in kelps is probably regulated at the scale of individually stimulated cells and that changes in blade morphology are likely brought about through changes in the direction of cell growth and/or division (Ch. 2). I then examined the effects of auxin on Nereocystis blade growth and morphology and considered whether auxin could play a role in mediating kelp plasticity. I found that auxin can have morphogenic effects in Nereocystis blade tissue that are remarkably similar to the effects of tension (Ch. 3). Next, I tested whether culturing the kelp Macrocystis pyrifera in reduced concentrations of Ca²⁺ could inhibit the growth response to mechanical loading, which would suggest that Ca²⁺ signaling might play a role in regulating plasticity. No evidence arose that reducing the ambient Ca²⁺ concentration could inhibit plasticity (Ch. 4). Furthermore, all Ca²⁺ reductions greater than 50% proved lethal for kelps (Ch. 4). Finally, I investigated how prevalent phenotypic plasticity across hydrodynamic gradients is in various algal groups and considered whether mechanisms of flow perception could limit the evolution of such plasticity. I found that (1) researchers examining intraspecific variation across flow gradients in seaweeds usually have not tested for plasticity and (2) verified plasticity has been documented more frequently in brown algae with intercalary growth than it has in other macroalgae (Ch. 5).

description: With an increasing focus on data privacy, there have been pilot studies on recommender systems in a federated learning (FL) framework, where multiple parties collaboratively train a model without sharing their data. Most of these studies assume that the conventional FL framework can fully protect user privacy. However, there are serious privacy risks in matrix factorization in federated recommender systems based on our study. This paper first provides a rigorous theoretical analysis of the server reconstruction attack in four scenarios in federated recommender systems, followed by comprehensive experiments. The empirical results demonstrate that the FL server could infer users' information with accuracy >80% based on the uploaded gradients from FL nodes. The robustness analysis suggests that our reconstruction attack analysis outperforms the random guess by >30% under Laplace noises with b no larger than 0.5 for all scenarios. Then, the paper proposes a new privacy-preserving framework based on homomorphic encryption, Privacy-Preserving Multi-View Matrix Factorization (PrivMVMF), to enhance user data privacy protection in federated recommender systems. The proposed PrivMVMF is successfully implemented and tested thoroughly with the MovieLens dataset.

description: The analytic continuation of the gluon propagator is revised in the light of recent findings on the possible existence of complex conjugated poles. The contribution of the anomalous pole must be added when Wick rotating, leading to an effective Minkowskian propagator which is not given by the trivial analytic continuation of the Euclidean function. The effective propagator has an integral representation in terms of a spectral function which is naturally related to a set of elementary (complex) eigenvalues of the Hamiltonian, thus generalizing the usual Källen-Lehmann description. A simple toy model shows how the elementary eigenvalues might be related to actual physical quasiparticles of the non-perturbative vacuum.

description: Waste plastic, though largely considered an environmental concern, has the potential to be a valuable resource. Some researchers have proposed mixing waste plastic with asphalt binder to make asphalt for the Nation’s roadways. Use of waste plastics to supplement traditional asphalt binders can reduce resource consumption and become an alternative to the disposal of waste plastic in landfills. However, challenges exist with using waste plastics in asphalt. In particular, knowledge of the compatibility of waste plastic—and the different types of polymers waste plastic is made of—with asphalt binders is limited. The Federal Highway Administration’s (FHWA’s) Exploratory Advanced Research (EAR) Program is supporting a 3-yr project, the first of its kind, to investigate and develop a computational model that can understand—on a molecular and atomic level—which waste polymers are compatible with which given asphalt binders to optimize the blend’s performance. Through this computational model, the researchers aim to provide a foundation for utilizing waste plastic in asphalt pavements on an industrial scale. A research team at Louisiana Tech University is conducting this study, awarded in September 2020, titled, “Improving the Compatibility of Waste Plastic and Asphalt Binder Via Theoretically Justified Identification of Compatible Blends.”

description: We generated 1.7-cycle and 35-$μ$J pulses at a 1-MHz repetition rate by using two-stage multiple plate continuum compression of Yb-laser pulses with 80-W average input power. By adjusting the plate positions with careful consideration of the thermal lensing effect due to the high average power, we compressed the output pulse with a 184-fs initial duration to 5.7 fs by using only group-delay-dispersion compensation. This pulse achieved a sufficient beam quality ($M^2$ < 1.5) reaching a focused intensity over 10$^{14}$ W/cm$^2$ and a high spatial-spectral homogeneity (98%). Our study holds promise for a MHz-isolated-attosecond-pulse source for advanced attosecond spectroscopic and imaging technologies with unprecedentedly high signal-to-noise ratios.

description: Isospin triggering allows to distinguish coalescence from thermal production of light clusters in heavy ion collisions. Triggering on $Y(π^-) - Y(π^+)$ allows to select very neutron or proton rich final states. The deuteron (cluster) production with coalescence ($d \propto n \cdot p$) leads then to an inverse parabolic dependence of the deuteron yield on $ΔY_π$. In contrast, in a thermal model, cluster production is independent on $ΔY_π$. The observation of a maximum deuteron (cluster) yield as function of $ΔY_π$ provides confirmation of the coalescence mechanism.

description: Globular clusters have proven to be essential to our understanding of many important astrophysical phenomena. Here we analyse spectroscopic observations of ten Halo globular clusters to determine their dark matter content, their tidal heating by the Galactic disc and halo, describe their metallicities and the likelihood that Newtonian dynamics explain their kinematics. We analyse a large number of members in all clusters, allowing us to address all these issues together, and we have included NGC 288 and M30 to overlap with previous studies. We find that any flattening of the velocity dispersion profiles in the outer regions of our clusters can be explained by tidal heating. We also find that all our GCs have M/L_V < 5, therefore, we infer the observed dynamics do not require dark matter, or a modification of gravity. We suggest that the lack of tidal heating signatures in distant clusters indicates the Halo is not triaxial. The isothermal rotations of each cluster are measured, with M4 and NGC 288 exhibiting rotation at a level of 0.9 +/- 0.1 km/s and 0.25 +/- 0.15 km/s, respectively. We also indirectly measure the tidal radius of NGC 6752, determining a more realistic figure for this cluster than current literature values. Lastly, an unresolved and intriguing puzzle is uncovered with regard to the cooling of the outer regions of all ten clusters.

description: Cosmic voids are known as underdense substructures of the cosmic web that cover a large volume of the Universe. It is known that cosmic voids contain a small number of dark matter halos, so the existence of primordial black holes (PBHs) in these secluded regions of the Universe is not unlikely. In this work, we calculate the merger rate of PBHs in dark matter halos structured in cosmic voids and determine their contribution to gravitational wave events resulting from black hole mergers recorded by the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO)-Advanced Virgo (aVirgo) detectors. Relying on the PBH scenario, the results of our analysis indicate that about $2 \sim 3$ annual events of binary black hole mergers out of all those recorded by the aLIGO-aVirgo detectors should belong to cosmic voids. We also calculate the redshift evolution of the merger rate of PBHs in cosmic voids. The results show that the evolution of the merger rate of PBHs has minimum sensitivity to the redshift changes, which seems reasonable while considering the evolution of cosmic voids. Finally, we specify the behavior of the merger rate of PBHs as a function of their mass and fraction in cosmic voids and we estimate $\mathcal{R} (M_{PBH}, f_{PBH})$ relation, which is well compatible with our findings.
