description: Spinel MgAl2O4 and family oxides are emerging barrier materials useful for magnetic tunnel junctions (MTJs). We report large tunnel magnetoresistance (TMR) ratios up to 429% at room temperature (RT) and 1,034% at 10 K in a Fe/MgAl2O4/Fe(001)-based MTJ prepared using electron-beam evaporation of Mg4Al-Ox. Resistance oscillations with a MTJ barrier thickness of 0.3-nm were significantly enhanced compared to those of a Fe/MgO/Fe(001) MTJ, resulting in a large TMR oscillation peak-to-valley difference of 125% at RT. The differential conductance spectra were symmetric with bias polarity, and the spectrum in the parallel magnetization state at low temperature demonstrate significant peaks within broad local minima at |0.2-0.6| V, indicating improved barrier interfaces by the Mg4Al-Ox barrier. This study demonstrates that TMR ratios in Fe(001)-MTJs can still be improved.

description: It is found that CP symmetry may be explicitly broken in the Higgs sector of a supersymmetric $E_6$ model with two extra neutral gauge bosons at the one-loop level. The phenomenology of the model, the Higgs sector in particular, is studied for a reasonable parameter space of the model, in the presence of explicit CP violation at the one-loop level. At least one of the neutral Higgs bosons of the model might be produced via the $WW$ fusion process at the Large Hadron Collider.

description: Since its introduction in 1963, the Hubbard model has becomes one of the most popular models used in the literature to study cooperative phenomena in narrow-band metals (ferromagnetism, metal-insulator transitions, charge-density waves, high-T$_c$ superconductivity). Amongst all these cooperative phenomena, the problem of itinerant ferromagnetism in the Hubbard model has the longest history. However, in spite of an impressive research activity in the past, the underlying physics (microscopic mechanisms) that leads to the stabilization of itinerant ferromagnetism in Hubbard model (narrow-band metals) is still far from being understood. In this review we present our numerical results concerning this subject, which have been reached by small cluster exact diagonalization, density matrix renormalization group and quantum Monte Carlo calculations within various extensions of the Hubbard model. Particular attention is paid to a description of crucial mechanisms (interactions) that support the stabilization of the ferromagnetic state, and namely: (i) the long-range hopping, (ii) the correlated hopping, (iii) the long-range Coulomb interaction, (iv) the flat bands and (v) the lattice structure. Most of the presented results have been obtained for the one-dimensional case, but the influence of the increasing dimension of the system on the ferromagnetic state is also intensively discussed.

description: In- and out-of-plane magnetic penetration depths were measured in three iron-based pnictide superconducting systems. All studied samples of both 122 systems show a robust power-law behavior, $λ(T) T^n$, with the sample-dependent exponent n=2-2.5, which is indicative of unconventional pairing. This scenario could be possible either through scattering in a $s_{\pm }$ state or due to nodes in the superconducting gap. In the Nd-1111 system, the interpretation of data may be obscured by the magnetism of rare-earth ions. The overall anisotropy of the pnictide superconductors is small. The 1111 system is about two times more anisotropic than the 122 system. Our data and analysis suggest that the iron-based pnictides are complex superconductors in which a multiband three-dimensional electronic structure and strong magnetic fluctuations play important roles.

description: The presidential elections in the United States on 3 November 2020 have caused extensive discussions on social media. A part of the content on US elections is organic, coming from users discussing their opinions of the candidates, political positions, or relevant content presented on television. Another significant part of the content generated originates from organized campaigns, both official and by astroturfing. In this study, we obtain approximately 17.5M tweets containing 3M users, based on prevalent hashtags related to US election 2020, as well as the related YouTube links, contained in the Twitter dataset, likes, dislikes and comments of the videos and conduct volume, sentiment and graph analysis on the communities formed. Particularly, we study the daily traffic per prevalent hashtags, plot the retweet graph from July to September 2020, show how its main connected component becomes denser in the period closer to the elections and highlight the two main entities ('Biden' and 'Trump'). Additionally, we gather the related YouTube links contained in the previous dataset and perform sentiment analysis. The results on sentiment analysis on the Twitter corpus and the YouTube metadata gathered, show the positive and negative sentiment for the two entities throughout this period. The results of sentiment analysis indicate that 45.7% express positive sentiment towards Trump in Twitter and 33.8% positive sentiment towards Biden, while 14.55% of users express positive sentiment in YouTube metadata gathered towards Trump and 8.7% positive sentiment towards Biden. Our analysis fill the gap between the connection of offline events and their consequences in social media by monitoring important events in real world and measuring public volume and sentiment before and after the event in social media.

description: We present the capabilities of the CMS experiment to explore the heavy-ion physics program offered by the CERN Large Hadron Collider (LHC). The prime goal of this research is to test the fundamental theory of the strong interaction (QCD) in extreme conditions of temperature, density and parton momentum fraction by colliding nuclei at energies of sqrt(s_NN) = 5.5 TeV. This presentation will give the overview of the potential of the CMS to carry out a full set of representative Pb-Pb measurements both in "soft" and "hard" regimes. Measurements include "bulk" observables -- charged hadron multiplicity, low pT inclusive hadron identified spectra and elliptic flow -- which provide information on the collective properties of the system; as well as perturbative processes - such as quarkonia, heavy-quarks, jets, gamma-jet, and high pT hadrons -- which yield "tomographic" information of the hottest and densest phases of the reaction.

description: A very large number of people use Online Social Networks daily. Such platforms thus become attractive targets for agents that seek to gain access to the attention of large audiences, and influence perceptions or opinions. Botnets, collections of automated accounts controlled by a single agent, are a common mechanism for exerting maximum influence. Botnets may be used to better infiltrate the social graph over time and to create an illusion of community behavior, amplifying their message and increasing persuasion. This paper investigates Twitter botnets, their behavior, their interaction with user communities and their evolution over time. We analyzed a dense crawl of a subset of Twitter traffic, amounting to nearly all interactions by Greek-speaking Twitter users for a period of 36 months. We detected over a million events where seemingly unrelated accounts tweeted nearly identical content at nearly the same time. We filtered these concurrent content injection events and detected a set of 1,850 accounts that repeatedly exhibit this pattern of behavior, suggesting that they are fully or in part controlled and orchestrated by the same software. We found botnets that appear for brief intervals and disappear, as well as botnets that evolve and grow, spanning the duration of our dataset. We analyze statistical differences between bot accounts and human users, as well as botnet interaction with user communities and Twitter trending topics.

description: The self-affine mode of ice softening during friction is investigated within the rheological model for viscoelastic medium approximation. The different modes of ice rubbing, determined by formation of surface liquid-like layer, are studied. The analysis of time series of friction force is carried out, namely Fourier analysis, construction of autocorrelation and difference autocorrelation functions. The spectral power law is detected for modes of crystalline ice as well as of a mixture of stable ice and metastable softening. The self-similarity and aperiodic character of corresponding time series of friction force are proved.

description: A search for a correlation between the luminosities of the brightest stars and luminosities of their host galaxies was carried out on archived Hubble Space Telescope (HST) F606W or F555W (V) and F814W (I) images of about 150 nearby galaxies. The sample contains only galaxies with on-going star formation (SF) and with known distances we derived with the TRGB-method. We correlated the average absolute luminosities of the three brightest blue and the three brightest red stars with the luminosity of a host. We found a linear relation for both the blue and the red stars in irregular and low-mass spiral galaxies. Their scatters are sufficiently small (0.m4) to make this relations useful for distance determination for low-mass galaxies. We found that all 31 dwarf galaxies (M_B>-13m) in our sample lack bright stars (M_V(BS)< -7.m0), probably due to the physical conditions that prevent their birth. For galaxies with higher luminosity in the range -18m

description: After extensively reviewing general relativistic gravitomagnetism, both historically and phenomenologically, we review in detail the so-called magnetic components of gravitational waves (GWs), which have to be taken into account in the context of the total response functions of interferometers for GWs propagating from arbitrary directions. Following the more recent approaches of this important issue, the analysis of such magnetic components will be reviewed in both of standard General Theory of Relativity (GTR) and Scalar Tensor Gravity. Thus, we show in detail that such a magnetic component becomes particularly important in the high-frequency portion of the range of ground based interferometers for GWs which arises from the two different theories of gravity. Our reviewed results show that if one neglects the magnetic contribution to the gravitational field of a GW, approximately 15% of the potential observable signal could, in principle, be lost.

We present an extensive experimental evaluation on five different corpora of user-generated comments, scientific publications, and persuasive essays. Our results show that our approach is a strong competitor against state-of-the-art architectures with a higher computational footprint or corpus-specific design, representing an interesting compromise between generality, performance accuracy and reduced model size.

description: Author’s variants: Invenzioni su una voce by Bruno Maderna
The analogue audio documents, containing the Electronic works of the second half of the XX Century, are often the result of a transmission process whose phe-nomenology, although it presents some peculiarities, shows analogies with the tex-tual tradition. In this context, Dimensioni II. Invenzione su una voce by Bruno Mad-erna is an interesting case study: the more than twenty reviewed sources, which are different for duration, content, and recording format; the existence of at least five author’s variants; the many relations among the Helm’s text, the Berberian’s per-formance, the electronic elaborations, and the tape editing process require edition criteria able to render the tradition of the work in its complex articulation. 
This paper gives a detailed analysis of the audio sources of Invenzione su una voce, based on a deep knowledge of the electronic “writing system”, by mean of which the work has been generated.

description: In an attempt to better understand structural benefits and generalization power of deep neural networks, we firstly present a novel graph theoretical formulation of neural network models, including fully connected, residual network (ResNet) and densely connected networks (DenseNet). Secondly, we extend the error analysis of the population risk for two layer network \cite{ew2019prioriTwo} and ResNet \cite{e2019prioriRes} to DenseNet, and show further that for neural networks satisfying certain mild conditions, similar estimates can be obtained. These estimates are a priori in nature since they depend sorely on the information prior to the training process, in particular, the bounds for the estimation errors are independent of the input dimension.
Phase separation dynamics in aqueous solutions of thermoresponsive polymers

description: Phase transition kinetics of aqueous hydroxypropyl cellulose solution was studied by using turbidimetric monitoring and mathematical modelling techniques. Based on the nonlinear Cahn-Hilliard equation with a mobility depending on the component concentration, the phase separation has been modeled on a simple one-dimensional Flory lattice. For value set of the interfacial energy parameter, data were obtained on the changing of the average values of the cluster sizes, their mass and concentration. The simulation results allow us to distinguish three stages of the spinodal decomposition: early, intermediate and final. It was found that for the intermediate stage, the kinetics of the cluster mass growth is described by a dependence that is characteristic of the usual diffusion mass transfer; the change in the average cluster size can be represented by a scaling function with an exponent close to 1/3, typical of the systems with a conserved scalar order parameter. It is shown that the concentration of clusters at the final stage is determined by the temperature dependence of the interfacial energy.

description: BACKGROUND/OBJECTIVE: Living in a food-insecure household may increase the risk for disordered eating. Though the Supplemental Nutrition Assistance Program (SNAP) was designed to reduce food insecurity, it may increase risk for disordered eating with the frequency in which benefits are distributed. Limited research has explored the lived experiences of managing eating behaviors while on SNAP, particularly among SNAP participants in larger bodies, and during COVID-19. Thus, the purpose of this study is to examine the experiences with eating behaviors among adults with a BMI ≥ 25 kg/m2, and who received SNAP benefits during the COVID-19 pandemic. METHODS: Eligible adults were recruited to participate in a semi-structured interview. Interviews were transcribed verbatim and analyzed using thematic analysis and content analysis. RESULTS: Participants (N = 16), had a mean (±SD) age of 43.4 ± 10.9 years, and overwhelmingly identified as female (86 %). One-third of the participants were Black. We identified 4 main themes: (1) not having enough money/benefits to cover needs; (2) navigating loss of control and emotional eating; (3) making sure the kids are alright; and (4) still feeling the pressure to manage weight. CONCLUSION: Managing eating behaviors while also navigating SNAP benefits is complex and may exacerbate risk of disordered eating.

This new form of coupler, based upon the compound Josephson junction rf-SQUID, provides a sign and magnitude tunable mutual inductance between qubits with minimal nonlinear crosstalk from the coupler tuning parameter into the qubits. Quantitative agreement is shown between an effective one-dimensional model of the coupler's potential and measurements of the coupler persistent current and susceptibility.

Landbanking in Red Deer
Creators: name: Watson, Kenneth Frank
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is about "landbanking". The case study of Red Deer was chosen to illuminate the concept rather than vice versa. The case of Red Deer is interesting in itself but has a wider importance because the Federal Government in Canada and several Provincial Governments have recently pledged massive financial support of local "landbanks". This study is not a micro-empirical study of a particular land market but is concerned with a certain policy and its market implications. The focus is on landbanking as a system of urban land conversion in which government agencies play a direct and active role instead of a passive regulatory role. Landbanking has been a particularly confused and contentious topic, the first three chapters of this thesis attempt to clear away this confusion by an analysis of the concept and the relevant literature. Several distinct "schools of thought" on landbanking are identified and several erroneous conceptions are refuted. The economics of landbanking and particularly those issues relevant to a cost-benefit analysis are examined in depth in the methodology chapter. The next three chapters are a detailed case study of the Red Deer landbank from its inception to December 31, 1972. The legal framework of its operation, the administration of the program, the financial history of the program, and the policies that structured the landbank are examined. Example subdivisions are analysed. The final chapter, is a cost-benefit evaluation of the landbank which relies on the conceptual base established in the earlier chapters and the empirical data gathered in the case study.

description: Microarchitectural attacks are a growing threat to modern computing systems. CPU caches are an essential but complex element in many microarchitectural attacks, making it crucial to understand the inner workings. Despite progress in reverse-engineering techniques, non-linear cache-slice functions remain challenging to analyze, especially in recent Intel hybrid microarchitectures.

In this paper, we introduce a novel approach towards reverse-engineering complex, non-linear cache-slice functions, particularly on modern Intel CPUs with hybrid microarchitectures. Our method significantly advances prior work by understanding the specific structure of microarchitectural hash functions, reducing the time required for reverse-engineering from days to minutes. In contrast to prior work, our technique successfully handles systems with 512GB of memory and diverse slice configurations. We present 17 newly identified functions used for cache-slice addressing and extend existing functions to support systems with more DRAM for multiple CPU generations. Additionally, we introduce an unprivileged virtual-to-physical address oracle that is a direct consequence of the complexity of the non-linear slice functions. Our method is particularly effective on modern Intel hybrid CPUs, including Alder Lake and Meteor Lake, where previously used methods for measuring slices or leaking physical addresses are unavailable. In 3 case studies, we validate our approach, demonstrating its effectiveness in executing targeted Spectre attacks on non-attacker-mapped memory, enabling DRAMA attacks, and creating cache eviction sets. Our findings emphasize the increased attack surface introduced by complex cache-slice functions in modern CPUs.

description: Background: The efficacy of vaccination depends on its widespread adoption, making vaccine uptake not just a personal health behavior but also a prosocial one. Previous research has shown that everyday moments of co-experienced positive emotions (positivity resonance) are associated with higher prosocial tendencies, and these moments, in turn, prospectively predict people's pandemic hygiene behaviors. Yet, limited research has explored how moments of positivity resonance may have predicted greater COVID-19 vaccine intentions during the early months of the pandemic. Methods: We longitudinally surveyed a national U.S. sample across four weeks during the fall of 2020. We tested the hypothesis that positivity resonance with strangers and acquaintances indirectly predicts COVID-19 vaccine intentions, as statistically mediated by prosocial tendencies. We also aimed to replicate the indirect effects of positivity resonance on hygiene behaviors (such as mask wearing and hand washing), effects that have been demonstrated in previous research. Results: In a pre-registered structural equation model, we found that perceived positivity resonance experienced with strangers and acquaintances prospectively predicted prosocial tendencies, which in turn amplified people's COVID-19 vaccine intentions (β = 0.053) and hygiene behaviors – i.e., social distancing (β = 0.032), mask wearing (β = 0.027), hand washing (β = 0.049). Conclusions: Understanding the effects of high-quality social interactions with strangers and acquaintances on vaccine intentions and hygiene behaviors is critical, particularly given the likelihood of emerging pandemics and novel vaccines. We discuss theoretical and practical implications related to perceived positivity resonance, prosocial tendencies, and vaccination uptake for novel vaccines.

description: The spectrum of tight binding electrons on a square lattice with half a magnetic flux quantum per unit cell exhibits two Dirac points at the band center. We show that, in the presence of an additional uniaxial staggered potential, this pair of Dirac points may merge into a single one, with a topological transition towards a gapped phase. At the transition, the spectrum is linear in one direction and quadratic in the other one (a spectrum recently named "hybrid" or "semi-Dirac"). This transition is studied in the framework of a general Hamiltonian describing the merging of Dirac points. The possibility of creating gauge fields for cold atoms in optical lattices may offer the first opportunity to observe this merging of Dirac points and the hybrid dispersion relation.

description: Smart home environments are designed to provide services that help improve the quality of life for the occupant via a variety of sensors and actuators installed throughout the space. Many automated actions taken by a smart home are governed by the output of an underlying activity recognition system. However, activity recognition systems may not be perfectly accurate and therefore inconsistencies in smart home operations can lead users reliant on smart home predictions to wonder "why did the smart home do that?" In this work, we build on insights from Explainable Artificial Intelligence (XAI) techniques and introduce an explainable activity recognition framework in which we leverage leading XAI methods to generate natural language explanations that explain what about an activity led to the given classification. Within the context of remote caregiver monitoring, we perform a two-step evaluation: (a) utilize ML experts to assess the sensibility of explanations, and (b) recruit non-experts in two user remote caregiver monitoring scenarios, synchronous and asynchronous, to assess the effectiveness of explanations generated via our framework. Our results show that the XAI approach, SHAP, has a 92% success rate in generating sensible explanations. Moreover, in 83% of sampled scenarios users preferred natural language explanations over a simple activity label, underscoring the need for explainable activity recognition systems. Finally, we show that explanations generated by some XAI methods can lead users to lose confidence in the accuracy of the underlying activity recognition model. We make a recommendation regarding which existing XAI method leads to the best performance in the domain of smart home automation, and discuss a range of topics for future work to further improve explainable activity recognition.

Mediazione e responsabilità, nel suono
Creators: name: Di Scipio, Agostino
Publisher: name: Musica/Tecnologia
Year: 2010

description: Agostino Di Scipio, questioning the relationship between music, technology and society, points to the need of abandoning a strictly sociological point of view in favor of an approach that considers the actions and decisions mediated through technology – together with the responsibility the composer assumes on these processes of mediation – in their capacity to trace elements capable to be audible within the conditions of existence of sound and music. Through a series of steps – which go from a hermeneutic of technology to the identification of paradigms of mediation, from the definition of the conditions for responsibility, to the assessment of the nature of the plurality of tracks left in the sound from the constructive gesture – the author points out the terms of a perspective informed to the creative practice, the conditions and the techniques of those who act in a creative sense. In a world structured as a network of interconnected technical systems, the reflection must be brought from the aesthetic plane to the more decisive one of ‘responsibility of the media’, where “the skills and awareness that a musician has of the technologies of his work are not secondary to the meaning and significance of the final products of his work”.

description: The new structures, Cmc2$_1$-Si$_2$P$_2$X (X=S, Se, Te, and Po), are predicted, and their mechanical, electronic and optical properties are investigated with the density functional theory, by first principles calculations. The elastic constants of the four compounds are calculated by the stress-strain method. The calculations of the elastic stability criteria and phonon dispersion spectra imply that they are mechanically and dynamically stable at zero pressure. The mechanical parameters, such as shear moduli $G$, bulk moduli $B$, Young's moduli $E$ and Poisson's ratios $v$ are evaluated by the Voigt-Reuss-Hill approach. The Cmc2$_1$-Si$_2$P$_2$X has the largest hardness due to the largest Young's modulus in the four compounds, and it is a covalent crystal. The anisotropies of their mechanical properties are also analyzed. The band structures and densities of states, which are calculated by using HSE06, show that Cmc2$_1$-Si$_2$P$_2$X compounds are indirect bandgap semiconductors, and the values of the band gaps decrease with increasing atomic number from S, Se, Te, to Po. In addition, the longitudinal sound velocity and transverse sound velocity for Cmc2$_1$-Si$_2$P$_2$X have been investigated. The dielectric constant, electron energy loss, refractive index, reflectivity, absorption and conductivity are analyzed to gain the optical properties of Si$_2$P$_2$X.

Re-Staging the 1934 Abbey Theatre Production of Yeats’s The King of the Great Clock Tower: An Evaluation and Critique
Creators: name: Cave, Richard Allen
Publisher: name: Biblioteca di Studi di Filologia Moderna: Series, Journals and Workshop
Year: 2013

description: This essay investigates and critiques an attempt from the surviving evidence to re-stage the first performance of Yeats’s The King of the Great Clock Tower at the Abbey Theatre in 1934. This dance-drama was the last of four collaborations between the playwright and the dancer-choreographer, Ninette de Valois, during the period when she established for him a School of Ballet at the Abbey in Dublin. A wealth of evidence survives from which a performance text (as distinct from the printed text) may be inferred. The limitations to be found in various kinds of extant data concerning performance (music scores, set designs, photographs, revisions to play scripts, reviews, correspondence, reminiscence) are discussed in the light of the writer’s experience of bringing such a re-staging into production. The dangers of overly hypothesising or historicising are examined and devices for negotiating gaps in the evidence while being wholly transparent in one’s efforts are discussed. Finally the essay explores the many and diverse levels of collaboration on which a successful staging of one of Yeats’s dancedramas depends. In the course of that discussion the meaning of the word, collaboration, is interrogated and to some degree re-defined.

description: With analyzing the mass function obtained by solving Dyson-Schwinger Equations, we propose a cut-off independent definition of quark condensate beyond chiral limit. With this well-defined condensate, we then analyze the evolution of the condensate and its susceptibility with the current quark mass. The susceptibility shows a critical mass in the neighborhood of the s-quark current mass, which defines a transition boundary for internal hadron dynamics.

description: Objective: COVID-19 infection has been demonstrated to increase risk for post-operative bleeding. This study investigated the impact of COVID-19 infection on post-tonsillectomy hemorrhage in pediatric patients, a potentially devastating complication. Study design: Retrospective cohort study. Methods: The TriNetX database was queried for pediatric patients who underwent tonsillectomy and evaluated for outcomes of primary and secondary post-tonsillectomy hemorrhage. Results: Among subjects 18 years and younger, 1226 were COVID-19 positive and 38,241 were COVID-19 negative in the perioperative period. There was statistically significant increased risk of bleeding with perioperative COVID-19 infection at postoperative days 1, 5, and 10. Additionally, when assessing the role of COVID-19 infection before or after surgery, the risk of bleeding remained statistically significant at all three time points, however these results did not suggest that infection before surgery confers more/less risk compared to infection after. Conclusion: The results of this investigation suggest that the presence of COVID-19 in the perioperative period may pose an increased risk for acute or delayed post tonsillectomy hemorrhage. This study employed a large, diverse population and is the first to address this clinical question.

Jackstraw inference for AJIVE data integration

description: In the age of big data, data integration is a critical step especially in the understanding of how diverse data types work together and work separately. Among data integration methods, the Angle-Based Joint and Individual Variation Explained (AJIVE) approach is particularly attractive because it not only studies joint behavior but also individual behavior. Typically AJIVE scores indicate important relationships between data objects, such as clusters. An important challenge is understanding which features, i.e. variables, are associated with those relationships. This challenge is addressed by the proposal of a hypothesis test for assessing statistical significance of features. The new test is inspired by the related jackstraw method developed for Principal Component Analysis. We use a high-dimensional multi-genomic cancer data set as our strong motivation and deep illustration of the methodology.

Aging and the emerging role of cellular senescence in osteoarthritis
Creators: name: Diekman, Brian O

description: OBJECTIVE: The correlation between age and incidence of osteoarthritis (OA) is well known but the causal mechanisms involved are not completely understood. This narrative review summarizes selected key findings from the past 30 years that have elucidated key aspects of the relationship between aging and OA. METHODS: The peer-reviewed English language literature was searched on PubMed using keywords including senescence, aging, cartilage, and osteoarthritis, for original studies and reviews published from 1993 to 2023 with a major focus on more recent studies. Manuscripts most relevant to aging and OA that examined one or more of the hallmarks of aging were selected for further review. RESULTS: All proposed hallmarks of aging have been observed in articular cartilage and some have also been described in other joint tissues. Hallmarks include genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, altered intercellular communication, disabled macroautophagy, chronic inflammation, and dysbiosis. There is evidence that these age-related changes contribute to the development of OA in part by promoting cellular senescence. Senescence may therefore serve as a downstream mediator that connects numerous aging hallmarks to OA, likely through the senescence-associated secretory phenotype that is characterized by increased production of proinflammatory cytokines and matrix metalloproteinases. CONCLUSIONS: Progress over the past 30â€¯years has provided the foundation for emerging therapies, such as senolytics and senomorphics, that hold promise for OA disease modification. Mechanistic studies utilizing physiologically-aged animals and cadaveric human joint tissues will be important for continued progress.
