High-pressure coal injection in the zinc slag fuming process
Creators: name: Cockcroft, Steven Lee
Publisher: name: University of British Columbia
Year: 2010

description: Zinc slag fuming is a kinetically controlled process based on the direct reduction of slag by entrained coal. The kinetics of the process are governed primarily by two factors: (1) the fraction of coal entrained in the slag, and (2) the rate of ferrous iron oxidation. A series of high-pressure coal injection trials have been completed at Cominco's lead smelter in Trail, British Columbia in order to facilitate increased coal entrainment. Fuming rates were increased substantially and over-all efficiencies were improved. These results are in direct contradiction to the predictions of models based on equilibrium. The kinetics based mathematical model of the zinc slag - fuming process originally developed by Richards and Brimacombe¹a has been modified to include the reduction and removal of lead from the furnace. A lead “prill” - slag reaction model has been formulated to account for the behaviour of liquid metallic lead. Analyses of the trial data with the modified model indicates that significant improvements in entrainment were achieved with high-pressure coal injection.

description: We present a class of sparse generalized linear models that include probit and logistic regression as special cases and offer some extra flexibility. We provide an EM algorithm for learning the parameters of these models from data. We apply our method in text classification and in simulated data and show that our method outperforms the logistic and probit models and also the elastic net, in general by a substantial margin.

description: Il danno da ischemia/riperfusione come causa di un ripristino ritardato della funzionalità degli organi trapiantati (DGF) rappresenta tutt’oggi una problematica non risolta, anche per la mancanza di sistemi e modelli sperimentali ben caratterizzati.In questo lavoro di tesi abbiamo sviluppato e caratterizzato un modello suino di DGF in seguito ad allotrapianto di rene ed abbiamo valutato l’effetto citoprotettivo dell’inalazione di monossido di carbonio (CO). La motivazione della scelta del modello suino, rispetto ai roditori, risiede nella nota similitudine dell’architettura del tessuto renale di questo animale a quello umano. In particolare, è stato utilizzato un modello standardizzato di ischemia renale, mediante il quale abbiamo dimostrato che il tempo di ischemia calda nel donatore riveste un ruolo fondamentale nel determinismo della DGF, ruolo evidenziato dal temporaneo aumento dei valori sierici di creatinina ed azoto ureico. La somministrazione di monossido di carbonio ai riceventi in sede intraoperatoria migliora notevolmente i tempi di recupero della funzionalità renale, come dimostrato dai parametri ematochimici del profilo renale, dall’istopatologia e dal profilo di espressione genica. In particolare, l’esposizione al CO riduce la necrosi tubulare acuta ed incrementa i processi di riparazione, determinando, inoltre, il blocco dell’espressione di alcuni geni pro-infiammatori a favore dei geni implicati nella risposta allo stress. Questo lavoro propone, per la prima volta, un modello sperimentale di DGF su animali di grossa taglia rivolto allo sviluppo di strategie terapeutiche indirizzate alla prevenzione/riduzione della DGF nell’uomo.

description: Bayesian neural networks have shown great promise in many applications where calibrated uncertainty estimates are crucial and can often also lead to a higher predictive performance. However, it remains challenging to choose a good prior distribution over their weights. While isotropic Gaussian priors are often chosen in practice due to their simplicity, they do not reflect our true prior beliefs well and can lead to suboptimal performance. Our new library, BNNpriors, enables state-of-the-art Markov Chain Monte Carlo inference on Bayesian neural networks with a wide range of predefined priors, including heavy-tailed ones, hierarchical ones, and mixture priors. Moreover, it follows a modular approach that eases the design and implementation of new custom priors. It has facilitated foundational discoveries on the nature of the cold posterior effect in Bayesian neural networks and will hopefully catalyze future research as well as practical applications in this area.

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: La tesi parte da un interrogativo: qual è il grado di effettività dei diritti fondamentali dei lavoratori nel commercio internazionale? Per rispondervi si partirà dall'individuazione di un "nucleo duro" di diritti dei lavoratori internazionalmente riconosciuti (i "core labour standards")e si valuterà la loro compatibilità con le ragioni del mercato. Successivamente si esaminerà il grado di effettività dei "core labour standards" nell'ordinamento dell'Organizzazione Internazionale del Lavoro e le possibili aperture alla "dimensione sociale" nell'ordinamento dell'Organizzazione Mondiale del Commercio. Infine, ci si soffermerà sulle tutele riconosciute ai diritti sociali fondamentali nell'ordinamento italiano e si valuterà la loro efficacia. In conclusione, rilevata una sostanziale ineffettività dei diritti sociali nell'ordinamento internazionale, si prospetteranno alcune modifiche agli strumenti di tutela, attualmente esistenti, per garantire loro una maggiore efficacia.

description: The phenomenological study of evolving galaxy populations has shown that star forming galaxies can be quenched by two distinct processes: mass quenching and environment quenching (Peng et al. 2010). To explore the mass quenching process in local galaxies, we study the massive central disk galaxies with stellar mass above the Schechter characteristic mass. In Zhang et al. (2019), we showed that during the quenching of the massive central disk galaxies as their star formation rate (SFR) decreases, their molecular gas mass and star formation efficiency drop rapidly, but their HI gas mass remains surprisingly constant. To identify the underlying physical mechanisms, in this work we analyze the change during quenching of various structure parameters, bar frequency, and active galactic nucleus (AGN) activity. We find three closely related facts. On average, as SFR decreases in these galaxies: (1) they become progressively more compact, indicated by their significantly increasing concentration index, bulge-to-total mass ratio, and central velocity dispersion, which are mainly driven by the growth and compaction of their bulge component; (2) the frequency of barred galaxies increases dramatically, and at a given concentration index the barred galaxies have a significantly higher quiescent fraction than unbarred galaxies, implying that the galactic bar may play an important role in mass quenching; and (3) the "AGN" frequency increases dramatically from 10% on the main sequence to almost 100% for the most quiescent galaxies, which is mainly driven by the sharp increase of LINERs. These observational results lead to a self-consistent picture of how mass quenching operates.

A Bird in the Hands: the role of verbal working memory and visuo-spatial working memory in children’s receptive speech-gesture integration

description: The use of the gesture to complement verbal language has proven a valuable tool for learning, understanding, and remembering information. Yet, in order to fully benefit from co-speech gesturing, one must be able to successfully integrate information across the two modalities. Little is known about the sources of individual cognitive differences that may help to explain discrepancies in one’s ability to integrate gesture and speech (Demir-Lira, 2018). In fact, the majority of earlier studies in the gestural literature have focused on group comparisons in order to understand multimodal language at a general level, eschewing an exploration of individual variation (Ozer and Goksun, 2020). Further, the majority of previous work has focused on the impact of childrens’ gestural production on comprehension, warranting a closer look at how gestural observation benefits the listener (Wu and Coulson, 2014). The current investigation explored the relationship between two aspects of individual difference in cognition, namely verbal working memory and visuo-spatial working memory, and speech-gesture integration. Children completed tasks to gauge these two aspects of working memory and then watched and listened to a story where ambiguous speech was simultaneously clarified with gesture. Crucially, in order to understand the global meaning of the story, a child would have to successfully integrate the speaker’s speech with his gesture. We found that higher rates of verbal working memory, but not visuo-spatial working memory, were associated with a greater likelihood of successful speech-gesture integration.

description: Modesty has always been regarded as a good virtue by the Chinese people, and only those Chinese who "don't know how high and mighty they are" will boast in front of everyone. As a result of social norms of modesty, Oriental people tend to present themselves in a low-profile, unobtrusive, and even self-depreciating manner. Does hiding success as a self-depreciating strategy incur interpersonal costs under the influence of Chinese cultural norms of modesty? Whether the hider incorrectly predicts the feelings or evaluations of the other party when hiding successes and failures are questions that require further research.

description: Recent wide-area surveys have enabled us to study the Milky Way with unprecedented detail. Its inner regions, hidden behind dust and gas, have been partially unveiled with the arrival of near-IR photometric and spectroscopic datasets. Among recent discoveries, there is a population of low-mass globular clusters, known to be missing, especially towards the Galactic bulge. In this work, five new low-luminosity globular clusters located towards the bulge area are presented. They were discovered by searching for groups in the multi-dimensional space of coordinates, colours, and proper motions from the Gaia EDR3 catalogue and later confirmed with deeper VVV survey near-IR photometry. The clusters show well-defined red-giant branches and, in some cases, horizontal branches with their members forming a dynamically coherent structure in proper motion space. Four of them were confirmed by spectroscopic follow-up with the MUSE instrument on the ESO VLT. Photometric parameters were derived, and when available, metallicities, radial velocities and orbits were determined. The new clusters Gran 1 and 5 are bulge globular clusters, while Gran 2, 3, and 4 present halo-like properties. Preliminary orbits indicate that Gran 1 might be related to the Main Progenitor, or the so-called ''low-energy'' group, while Gran 2, 3 and 5 appear to follow the Gaia-Enceladus-Sausage. This study demonstrates that the Gaia proper motions, combined with the spectroscopic follow-up and colour-magnitude diagrams, are required to confirm the nature of cluster candidates towards the inner Galaxy. High stellar crowding and differential extinction may hide other low-luminosity clusters.

A study of the manufacturing method and related mechanical properties of SiC reinforced aluminum
Creators: name: Wiskel, J. Barry
Publisher: name: University of British Columbia
Year: 2010

description: A study involving manufacturing and tensile testing was conducted to elucidate the mechanical properties of a SiC fibre reinforced aluminum. Areas analyzed included production methods, failure mechanisms, tensile behaviour and interfacial bonding. A well dispersed fibre distribution in the as cast composite was difficult to obtain. This arises from the high degree of intermingling of fibres in the as-received tows. The poor distribution can lead to incomplete fibre utilization and increase composite susceptibility to delamination damage. The strength of the composites tested were below that expected from a rule of mixtures (ROM) value. Fibre damage incurred during manufacturing and by the formation of aluminum carbide on the fibre surface are possible causes for this anomaly. Also, fibre/(matrix plastic deformation) interaction can lead to premature composite failure especially at the low volume fractions of fibres being analyzed. On a microscopic level good bonding between the fibre and matrix was observed. This adhesion was attributed to the formation of aluminum carbide at the fibre/matrix interface. Synergistic strengthening of the matrix was observed for several tensile samples. This phenomena may be attributed to fibre distribution altering the aluminum matrix deformation behaviour.

$B_{s,d} \to ππ,πK, KK$: Status and Prospects

description: Several years ago, it was pointed out that the U-spin-related decays $B_d\toπ^+π^-$, $B_s\to K^+K^-$ and $B_d\toπ^\mp K^\pm$, $B_s\to π^\pm K^\mp$ offer interesting strategies for the extraction of the angle gamma of the unitarity triangle. Using the first results from the Tevatron on the $B_s$ decays and the B-factory data on $B_{u,d}$ modes, we compare the determinations of gamma from both strategies, study the sensitivity on U-spin-breaking effects, discuss the resolution of discrete ambiguities, predict observables that were not yet measured but will be accessible at LHCb, explore the extraction of the width difference $ΔΓ_s$ from untagged $B_s\to K^+K^-$ rates, and address the impact of new physics. The data for the $B_d\toπ^+π^-$, $B_s\to K^+K^-$ system favour the BaBar measurement of direct CP violation in $B_d\toπ^+π^-$, which will be used in the numerical analysis, and result in a fortunate situation, yielding $γ=(66.6^{+4.3+4.0}_{-5.0-3.0})^\circ$, where the latter errors correspond to a generous estimate of U-spin-breaking effects. On the other hand, the $B_d\toπ^\mp K^\pm$, $B_s\to π^\pm K^\mp$ analysis leaves us with $26^\circ\leqγ\leq70^\circ$, and points to a value of the $B_s\to π^\pm K^\mp$ branching ratio that is larger than the current Tevatron result. An important further step will be the measurement of mixing-induced CP violation in $B_s\to K^+K^-$, which will also allow us to extract the $B^0_s$--$\bar B^0_s$ mixing phase unambiguously with the help of $B_s\to J/ψϕ$ at the LHC. Finally, the measurement of direct CP violation in $B_s\to K^+K^-$ will make the full exploitation of the physics potential of the $B_{s,d}\to ππ, πK, KK$ modes possible.

La "Cronaca del teatro San Carlino" di Salvatore Di Giacomo (1891)

Year: 2009

description: La "Cronaca del teatro San Carlino. Relazione al Ministero d’Istruzione Pubblica d’Italia 1738-1884", pubblicata nel 1891 a Napoli, pe’ tipi di Ferdinando Bideri, segna l’inizio dell’attività di erudito di Salvatore Di Giacomo, dopo quella di poeta, novelliere, autore di canzoni, giornalista e traduttore. Nell’ambito della tradizione teatrale napoletana questo testo rappresenta un caso isolato di narrazione storica ed insieme immaginaria dei fatti, seguita da un’attenta analisi critica e valutativa delle opere e degli autori citati. Della "Cronaca del teatro San Carlino" conserviamo due edizioni (1891 e 1895) che solo in parte testimoniano la sua reale diffusione. L’opera, infatti, cominciò a circolare già nei primi mesi del 1890 in «dispense». Il Nostro, attraverso la cronaca di questo teatro, crea un percorso di storia della commedia popolare che di fatto approda ad essere una proposta di commedia nuova e di un nuovo uso del dialetto. Per questo la Cronaca del teatro San Carlino è in realtà un racconto della letteratura teatrale napoletana dal 1738 al 1884, funzionale alla comprensione della poetica di Di Giacomo e della sua produzione teatrale.

Information is protected by designing an appropriate decoherence-free subspace for a cluster state resource. We demonstrate our scheme in an all-optical setup, encoding the information into the polarization states of four photons. A measurement-based one-way information-transfer protocol is performed with the photons exposed to severe symmetric phase-damping noise. Remarkable protection of information is accomplished, delivering nearly ideal outcomes.

description: Fast radio transient search algorithms identify signals of interest by iterating and applying a threshold on a set of matched filters. These filters are defined by properties of the transient such as time and dispersion. A real transient can trigger hundreds of search trials, each of which has to be post-processed for visualization and classification tasks. In this paper, we have explored a range of unsupervised clustering algorithms to cluster these redundant candidate detections. We demonstrate this for Realfast, the commensal fast transient search system at the Very Large Array. We use four features for clustering: sky position (l, m), time and dispersion measure (DM). We develop a custom performance metric that makes sure that the candidates are clustered into a small number of pure clusters, i.e, clusters with either astrophysical or noise candidates. We then use this performance metric to compare eight different clustering algorithms. We show that using sky location along with DM/time improves clustering performance by $\sim$10% as compared to the traditional DM/time-based clustering. Therefore, positional information should be used during clustering if it can be made available. We conduct several tests to compare the performance and generalisability of clustering algorithms to other transient datasets and propose a strategy that can be used to choose an algorithm. Our performance metric and clustering strategy can be easily extended to different single-pulse search pipelines and other astronomy and non-astronomy-based applications.

description: Low-precision formats have proven to be an efficient way to reduce not only the memory footprint but also the hardware resources and power consumption of deep learning computations. Under this premise, the posit numerical format appears to be a highly viable substitute for the IEEE floating-point, but its application to neural networks training still requires further research. Some preliminary results have shown that 8-bit (and even smaller) posits may be used for inference and 16-bit for training, while maintaining the model accuracy. The presented research aims to evaluate the feasibility to train deep convolutional neural networks using posits. For such purpose, a software framework was developed to use simulated posits and quires in end-to-end training and inference. This implementation allows using any bit size, configuration, and even mixed precision, suitable for different precision requirements in various stages. The obtained results suggest that 8-bit posits can substitute 32-bit floats during training with no negative impact on the resulting loss and accuracy.

description: We consider the atom-optical delta-kicked accelerator when the initial momentum distribution is symmetric. We demonstrate the existence of quantum-resonant dynamics, and derive analytic expressions for the system evolution. In particular, we consider the dynamical evolution of the momentum moments and find that all even-ordered momentum moments exhibit a power law growth. In the ultracold (zero-temperature) limit the exponent is determined by the order of the moment, whereas for a broad, thermal initial momentum distribution the exponent is reduced by one. To demonstrate the power law behavior explicitly we consider the evolutions of the second- and fourth-order momentum moments, and cumulants, for an initially Gaussian momentum distribution corresponding to the Maxwell-Boltzmann distribution of an ideal gas at thermal equilibrium.

Characterization and serotype distribution of Aggregatibacter actinomycetemcomitans detected in a population of periodontitis patients in Spain.
Creators: name: Blasi, Andrea
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: Objective:
To investigate the serotype distribution of Aggregatibacter actinomycetemcomitans (A. a.) and the polymorphism of the genes that codify the leukotoxin (ltx) and the operon of the cytolethal distending toxin (cdt) in periodontitis patients in Spain.
Materials and methods:
Forty A. a.-positive periodontitis patients were included in the study (mean age 45±7.8 years, 62.5 % female) and their clinical periodontal status was assessed. On average, 1 to 2 isolates from each patient were subcultured and characterized by specific PCR reactions.
Results:
Serotype distribution analysis concludes that the most frequent serotype was a and that 29 patients showed monoinfection. The 11 patients that showed coinfection were infected mostly with serotypes a and b.
From these 40 isolates 15 corresponded to serotype a, 8 to serotype b and 6 to serotype c. Monoinfection with serotypes d, e or f was not found.
Further characterization of these samples with leukotoxin specific PCR reaction showed that none of the 40 samples presented the 530-bp deletion called Δ530 in the leukotoxin’s promoter region, which characterizes the JP2 strain.
As for the Cdt, the operon that codifies for the toxin was present in 85 % of the samples.
Conclusions:
The most common serotypes were a and b. Serotype a was the most frequent in monoinfections, while serotypes d, e and f were not detected. In the majority of samples, operon that codifies the cdt (85%) and the genes responsible for the codification of leukotoxin (100%) were found. None of the isolates belonged to the JP2 strain.

description: Results from electric charge correlations studied with the Balance Function method in A+A collisions from 20\emph{A} to 158\emph{A} GeV are presented in two different rapidity intervals: In the mid-rapidity region we observe a decrease of the width of the Balance Function distribution with increasing centrality of the collision, whereas this effect vanishes in the forward rapidity region. Results from the energy dependence study in central Pb+Pb collisions show that the narrowing of the Balance Function expressed by the normalised width parameter \textit{W} increases with energy towards the highest SPS and RHIC energies. Finally we compare our experimental data points with predictions of several models. The hadronic string models UrQMD and HIJING do not reproduce the observed narrowing of the Balance Function. However, AMPT which contains a quark-parton transport phase before hadronization can reproduce the narrowing of the BF's width with centrality. This confirms the proposed sensitivity of the Balance Function analysis to the time of hadronization.

description: Face recognition has been one of the most relevant and explored fields of Biometrics. In real-world applications, face recognition methods usually must deal with scenarios where not all probe individuals were seen during the training phase (open-set scenarios). Therefore, open-set face recognition is a subject of increasing interest as it deals with identifying individuals in a space where not all faces are known in advance. This is useful in several applications, such as access authentication, on which only a few individuals that have been previously enrolled in a gallery are allowed. The present work introduces a novel approach towards open-set face recognition focusing on small galleries and in enrollment detection, not identity retrieval. A Siamese Network architecture is proposed to learn a model to detect if a face probe is enrolled in the gallery based on a verification-like approach. Promising results were achieved for small galleries on experiments carried out on Pubfig83, FRGCv1 and LFW datasets. State-of-the-art methods like HFCN and HPLS were outperformed on FRGCv1. Besides, a new evaluation protocol is introduced for experiments in small galleries on LFW.

description: È stato studiato un problema di scattering tra due particelle che interagiscono tramite un potenziale puntuale in tre dimensioni nel limite in cui una particella ha massa molto minore dell’altra. I risultati ottenuti hanno permesso di stimare gli effetti di decoerenza dinamicamente indotta su uno stato entangled della particella “pesante” che si ottengono quando la particella “leggera” viene utilizzata come misuratore per la posizione della particella “pesante”.
Utilizzando la teoria delle estensioni autoaggiunte è stato modellizzato un sistema in cui una particella quantistica (senza spin) interagisce con uno spin posto in un punto fissato dello spazio mediante un potenziale singolare dipendente dallo spin. È stata discussa la caratterizzazione di tutte le possibili hamiltoniane di interazione ottenibili come perturbazioni puntuali dell’hamiltoniana libera. In alcuni casi particolari è stato possibile ottenere espressioni esplicite per il propagatore. La conoscenza della dinamica esatta del sistema ha permesso di valutare esplicitamente l’attenuazione dei termini di interferenza quantistica in uno stato entangled dello spin, dovuta all’interazione con la particella.
È stato studiato un problema di interazione in una dimensione di un numero finito e infinito di sorgenti con il campo acustico. Lo scopo era quello di dimostrare che, in assenza di meccanismi di riflessione delle onde acustiche, il moto delle sorgenti risulta smorzato a causa dell’interazione con il proprio campo. Utilizzando la teoria delle estensioni autoaggiunte di operatori simmetrici è stata realizzata una formulazione del tutto nuova di tale problema. Tale formulazione ha permesso di ottenere risultati molto generali sullo smorzamento delle oscillazioni delle sorgenti.
Breaking the mass-sheet degeneracy with gravitational wave interference in lensed events

description: The mass-sheet degeneracy is a well-known problem in gravitational lensing which limits our capability to infer astrophysical lens properties or cosmological parameters from observations. As the number of gravitational wave observations grows, detecting lensed events will become more likely, and to assess how the mass-sheet degeneracy may affect them is crucial. Here we study both analytically and numerically how the lensed waveforms are affected by the mass-sheet degeneracy computing the amplification factor from the diffraction integral. In particular, we differentiate between the geometrical optics, wave optics and interference regimes, focusing on ground-based gravitational waves detectors. In agreement with expectations of gravitational lensing of electromagnetic radiation, we confirm how, in the geometrical optics scenario, the mass-sheet degeneracy cannot be broken with only one lensed image. However, we find that in the interference regime, and in part in the wave-optics regime, the mass-sheet degeneracy can be broken with only one lensed waveform thanks to the characteristic interference patterns of the signal. Finally, we quantify, through template matching, how well the mass-sheet degeneracy can be broken. We find that, within present GW detector sensitivities and considering signals as strong as those which have been detected so far, the mass-sheet degeneracy can lead to a $1σ$ uncertainty on the lens mass of $\sim 12\%$. With these values the MSD might still be a problematic issue. But in case of signals with higher signal-to-noise ratio, the uncertainty can drop to $\sim 2\%$, which is less than the current indeterminacy achieved by dynamical mass measurements.

The collective acronym FACTS has been adopted m recent years to describe a wide range of controllers, many of them incorporating large power electronic converters, which may, at present or in the future, be used to increase the flexibility of power systems and thus make them more controllable. Some of these controllers are already well established and some still in the research or development stage.
This document has been produced by CIGRE and the IEEE to give an overview of "Flexible AC Transmission Systems" (FACTS). FACTS has been defined by the IEEE as "alternating current transmission systems incorporating power electronic-based and other static controllers to enhance controllability and increase power transfer capability". Research institutions, utilities, and manufacturers throughout the world are pursuing programs with two main objectives:
�	to increase the power transfer capability of transmission networks
�	to provide direct control of power flow over designated transmission routes

The Joint Working Group C4/C2.58/IEEE was established to review voltage stability of power systems in the context of increased penetration of Inverter Based Resources (IBR) in electric power grids. The focus was to evaluate the adequacy of existing methods of voltage stability assessment in the present-day context. The developed technical brochure reviewed the definition of voltage stability and explained the role of voltage stability assessment within the voltage security assessment task of near real time power system operation. The overall conclusion is that the controllers implemented on IBRs makes a significant influence on short-term, but also long-term voltage stability. The presence of IBRs at distribution voltage levels contribute to the dynamic behavior of the power grid. Voltage stability assessment must incorporate these facts to ensure that the methods and tools accurately capture voltage stability limits.

description: Abstract : To gain a deeper understanding of the factors influencing health anxiety, this paper proposes a moderated mediating model to explore the interrelationships among compulsive Internet use, intolerance of uncertainty, information avoidance, and health anxiety. By analyzing these variables within the proposed framework, we aim to shed light on the complex dynamics that contribute to health anxiety.
Methods: This study included 239 randomly selected undergraduates. We used the Whiteley Index, Information Avoidance questionnaire, Compulsive Internet Use Scale, and Uncertainty Intolerance Questionnaire to comprehensively assess their behaviors and attitudes.
Results: (a) The study revealed a positive association between compulsive internet use and health anxiety. (b) Intolerance of uncertainty was identified as a mediator in the relationship between compulsive Internet use and health anxiety. (c) Information avoidance does not mediate the effects of compulsive internet use and intolerance of uncertainty on health anxiety; instead, it directly contributes to increased levels of health anxiety.
Conclusion: Compulsive internet use predicts and exacerbates health anxiety by increasing individuals' intolerance of uncertainty. Information avoidance directly exacerbates health anxiety. Effective interventions should focus on reducing compulsive internet use, enhancing tolerance for uncertainty, and addressing information avoidance tendencies to alleviate health anxiety. These findings provide valuable theoretical support for targeted health anxiety interventions.
