description: To investigate event-related activity in human brain dynamics as measured with EEG, triggers must be incorporated to indicate the onset of events in the experimental protocol. Such triggers allow for the extraction of ERP, i.e., systematic electrophysiological responses to internal or external stimuli that must be extracted from the ongoing oscillatory activity by averaging several trials containing similar events. Due to the technical setup with separate hardware sending and recording triggers, the recorded data commonly involves latency differences between the transmitted and received triggers. The computation of these latencies is critical for shifting the epochs with respect to the triggers sent. Otherwise, timing differences can lead to a misinterpretation of the resulting ERPs. This study presents a methodical approach for the CLET using a photodiode on a non-immersive VR (i.e., LED screen) and an immersive VR (i.e., HMD). Two sets of algorithms are proposed to analyze the photodiode data. The experiment designed for this study involved the synchronization of EEG, EMG, PPG, photodiode sensors, and ten 3D MoCap cameras with a VR presentation platform (Unity). The average latency computed for LED screen data for a set of white and black stimuli was 121.98 ± 8.71 ms and 121.66 ± 8.80 ms, respectively. In contrast, the average latency computed for HMD data for the white and black stimuli sets was 82.80 ± 7.63 ms and 69.82 ± 5.52 ms. The codes for CLET and analysis, along with datasets, tables, and a tutorial video for using the codes, have been made publicly available.
Resource quality impacts the immune system of the Indianmeal moth

description: Invertebrates are exposed to many pathogens and parasites during their life cycle. Host immune responses are sensitive to changes in resource quality due to trade-offs between life-history traits and immune defenses. However, we lack a full understanding of how trade-offs play out in the presence of a bacterial pathogen and varying qualities of food environment. In this study, we investigated whether resource quality in conjunction with bacterial infection alters the immune system of the insect species, Plodia interpunctella, commonly known as the Indian meal moth. We used a factorial design with food quality and pathogen presence varied for a total of eight treatment combinations. Larvae in the infected condition were infected by Bacillus turingiensis, a soil-dwelling, natural pathogen of Plodia Interpunctella. Total haemocyte count was estimated from all conditions of P. interpunctella larvae. We found significant differences in the total number of haemocyte cells between larvae reared in different food quality conditions, in both infected and uninfected larvae. Moreover, we found a significant difference in total haemocyte counts between infected and uninfected larvae, throughout food quality conditions. Finally, our results show a significant difference in the body mass of the larvae reared under varying food quality conditions. This work provides a deeper understanding of how insect immunity responds to bacterial pathogen infection throughout various food-quality environments. Specifically, how food quality and pathogen conditions interact to affect host immune responses. Furthermore, this information helps us understand and predict host-pathogen dynamics under changing environments.

description: A large number of unidentified sources found by astronomical surveys and other observations necessitate the use of an automated classification technique based on machine learning methods. The aim of this paper is to find a suitable automated classifier to identify the point X-ray sources in the Chandra Source Catalogue (CSC) 2.0 in the categories of active galactic nuclei (AGN), X-ray emitting stars, young stellar objects (YSOs), high-mass X-ray binaries (HMXBs), low-mass X-ray binaries (LMXBs), ultra luminous X-ray sources (ULXs), cataclysmic variables (CVs), and pulsars. The catalogue consists of approx 3,17,000 sources, out of which we select 2,77,069 point sources based on the quality flags available in CSC 2.0. In order to identify unknown sources of CSC 2.0, we use multi-wavelength features, such as magnitudes in optical/UV bands from Gaia-EDR3, SDSS and GALEX, and magnitudes in IR bands from 2MASS, WISE and MIPS-Spitzer, in addition to X-ray features (flux and variability) from CSC 2.0. We find the Light Gradient Boosted Machine, an advanced decision tree-based machine learning classification algorithm, suitable for our purpose and achieve $93\%$ precision, $93\%$ recall score and 0.91 Mathew's Correlation coefficient score. With the trained classifier, we identified 54,770 (14,066) sources with more than $3σ$ (4$σ$) confidence, out of which there are 32,600 (8,574) AGNs, 16,148 (5,166) stars, 5,184 (208) YSOs, 439 (46) HMXBs, 197 (71) LMXBs, 50 (0) ULXs, 89 (1) CVs, and 63 (0) pulsars. This method can also be useful for identifying sources of other catalogues reliably.

description: We study a driven-dissipative duo of two-level systems in an open quantum systems approach, modelling a pair of atoms or (more generally) meta-atoms. Allowing for complex-valued couplings in the setup, which are of both a coherent and incoherent character, gives rise to a diverse coupling landscape. We consider several points on this landscape, for example where the coupling between the two coupled two-level systems is dominated by coherent, incoherent, unsymmetrical and even unidirectional interactions. Traversing the coupling terrain leads to remarkable features in the populations of the pair, correlations and optical spectra. Most notably, the famous Mollow triplet spectrum for a single atom may be superseded for a pair by a Mollow quintuplet (or even by a spectral singlet) and the setup allows for population trapping to arise, all depending upon the precise nature of the coupling between the two-level systems.

description: Since the collapse of the Union of Soviet Socialist Republics (USSR), and especially in the 21st century, ties in identity and strategic alignment appear to be recurring themes in the context of military invasions by the Russian Federation into independent, former Soviet states. This thesis seeks to establish the roles of co-ethnicity and strategic alliance in the location of these interventions. This study accomplishes this task by analyzing both instances where invasions occurred and did not. The case studies include Georgia (2008), Ukraine (2014), Kazakhstan (2022), and Estonia (2007, 2015). The findings indicate that both co-ethnicity and strategic alignment are necessary factors for the location of intervention, although neither individually sufficient, and that strategic alliance may be a more deciding factor because of its potential influence on the former.

description: With the high flexibility of supporting resource-intensive and time-sensitive applications, unmanned aerial vehicle (UAV)-assisted mobile edge computing (MEC) is proposed as an innovational paradigm to support the mobile users (MUs). As a promising technology, digital twin (DT) is capable of timely mapping the physical entities to virtual models, and reflecting the MEC network state in real-time. In this paper, we first propose an MEC network with multiple movable UAVs and one DT-empowered ground base station to enhance the MEC service for MUs. Considering the limited energy resource of both MUs and UAVs, we formulate an online problem of resource scheduling to minimize the weighted energy consumption of them. To tackle the difficulty of the combinational problem, we formulate it as a Markov decision process (MDP) with multiple types of agents. Since the proposed MDP has huge state space and action space, we propose a deep reinforcement learning approach based on multi-agent proximal policy optimization (MAPPO) with Beta distribution and attention mechanism to pursue the optimal computation offloading policy. Numerical results show that our proposed scheme is able to efficiently reduce the energy consumption and outperforms the benchmarks in performance, convergence speed and utilization of resources.

description: Background: Primary lateral sclerosis (PLS) is a rare motor neuron disease characterized by progressive degeneration of upper motor neurons, resulting in spasticity and disability. There is, however, mounting evidence that the disease is not limited to upper motor neurons alone and that cognitive and behavioral changes within the spectrum of frontotemporal dementia (FTD) are part of the clinical phenotype. Objectives: To provide an in-depth classification of the cognitive and behavioral profiles of PLS by using the golden standard, a full neuropsychological evaluation, as well as a comprehensive behavioral assessment in a cohort of 30 cases. Results: Only 7 out of 30 PLS patients scored within normal range on all of the tests within our battery. The neuropsychological profile of PLS consists of deficits in social cognition (affective theory of mind (ToM) in particular), fluency, executive functions and memory. Using the revised Strong criteria, we could classify 57% of patients within the FTD spectrum (of which 17% had behavioral variant FTD). An additional 20% of patients had deficits which were not characteristic of FTD. Conclusions: This study confirms that PLS is not a restricted phenotype (only affecting upper motor neurons) and that behavioral and cognitive changes are common. Therefore, clinicians treating PLS patients should routinely assess cognition and behavior as part of routine care as cognitive and behavioral changes impact management, decision-making and care-giver burden. This assessment should be sensitive to the neuropsychological profile of PLS (social cognition (affective ToM in particular), fluency, executive functions and memory) and behavioral changes.

The author, one of the fathers and leaders of the American Performance Studies, focuses on the analysis of what he defines as “Global and Intercultural Performances”. In the second part of his writing, starting from the assumption that “anything can be studied ‘as’ performance”, Schechner makes the ‘performative’ example of the jihad/terrorism, in order to understand how terrorism works, how it functions in a globalized world, and why its effects are far in excess of its actual death or property toll.

Publisher: name: No Publisher Supplied
Year: 2023

description: There is limited and vague research regarding constant observation within psychiatric units. To date, in compliance with Joint Commission standards most facilities in the United States have created their own set of protocols. The project aims to evaluate current constant observation (CO) guidelines in a northeastern hospital in New Jersey. Using a retrospective chart review for the following period: May 2022- July 2022, constant observation initiation and discontinuation orders will be reviewed and assessed, verifying each order was paired with a current Columbia Suicide Severity Rating Scale. Then a comparison will be made between weekday and weekend data pertaining to having a C-SSRS completed for each CO between initiation and discontinuation will be completed. The following data will be obtained via the retrospective chart review: age, gender, diagnosis, length of hospitalization, duration of 1:1 order, date of 1:1 start, date of 1:1 ended, number of times the C-SSRS was completed per patient, the role of the provider (NP, MD) discontinuing the 1:1 order, and the day of the week the 1:1 order was discontinued. Evaluation of all data will lead to team discussions, suggested changes and implementation of improvements. Possible changes include: automatic EPIC prompts requiring providers to complete the C-SSRS and wall posters detailing the importance of pairing a C-SSRS with each initiation or discontinuation order for constant observation, strategically placed in the Behavioral Health’s Unit.

description: In the last twenty years, one of the most discussed theoretical issues in photography theory is certainly that concerning the relation between analogical photography and digital photography: are these art forms different, or is the latter just a technological upgrade of the former? Usually, in order to respond to this question, theorists turn their attention to the role assumed by the subjects (how users consider photography? Did they change the way to use it?) or to the device (is the “index” still intact, or does the digital conversion interrupt the process?). In this article, I will try to demonstrate that the question is wrong, and is based on a weak assumption; after a brief review of the debate on philosophy of photography, and on the so called post-photography, I will claim that the medial impact employed by the device on the subject (i.e. in this case the aesthetic function of the photographic picture) is caused by the prosthetic function arising from the medial regulation between individual and surrounding environment.

Magmatic and Hydrothermal Origins of The Buffalo Valley and Trenton Canyon Deposits of the Battle Mountain-Eureka Mining District, NV
Creators: name: Anna Strickland

Year: 2023

description: This  study utilizes whole rock analysis of major and trace elements as well as isotopic geochemistry of strontium and lead of 15 intrusive rock samples from the gold mining region of Buffalo Valley and two intrusive rock samples from the gold mine at Trenton Canyon in order to discern any similarities or differences in these two deposits that could lead to information about alteration, crystallization, and magmatic origins. Whole-rock geochemistry confirmed fluid interaction at both locations and showed differences between Buffalo Valley and Trenton Canyon. Initial isotopic compositions of Buffalo Valley revealed a fairly consistent crustal source whereas Trenton Canyon yields a different range of compositions, suggesting a source different to that of Buffalo Valley. The Sr system may hold age information about alteration events that occurred from the Eocene to the Oligocene at Buffalo Valley and Trenton Canyon. In contrast, the Pb system does not give any age information. High-precision U-Pb zircon dates are needed to evaluate any protolith and/or alteration age differences between the two locations.

description: Realizations of low firing rates in neural networks usually require globally balanced distributions among excitatory and inhibitory links, while feasibility of temporal coding is limited by neuronal millisecond precision. We show that cooperation, governing global network features, emerges through nodal properties, as opposed to link distributions. Using in vitro and in vivo experiments we demonstrate microsecond precision of neuronal response timings under low stimulation frequencies, whereas moderate frequencies result in a chaotic neuronal phase characterized by degraded precision. Above a critical stimulation frequency, which varies among neurons, response failures were found to emerge stochastically such that the neuron functions as a low pass filter, saturating the average inter-spike-interval. This intrinsic neuronal response impedance mechanism leads to cooperation on a network level, such that firing rates are suppressed towards the lowest neuronal critical frequency simultaneously with neuronal microsecond precision. Our findings open up opportunities of controlling global features of network dynamics through few nodes with extreme properties.

Pursuing Electrochemical Dinitrogen Fixation at a Rhenium Center
Creators: name: Spencer, Maya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: 	The Haber-Bosch process (HB) is an industrial process that converts atmospheric N2 to ammonia (NH3), which is a critical component of fertilizer. Despite the massive benefit that this process has brought to society, it is also detrimental to the environment. HB uses a lot of energy to maintain the reaction conditions required for NH3 production, and it also produces CO2 as a byproduct. We aim to develop catalysts capable of doing the same work as HB, but at a lower cost to the environment. A rhenium(V) dioxo has been synthesized using a ligand scaffold modeled off previous work in the field. This dioxo is air-stable and has been structurally characterized by XRD, and the two oxo ligands were revealed to be trans to each other, a rare configuration. This trans-dioxo configuration proved unreactive with a variety of reagents, but the molecule can be chemically reduced in the presence of acid to a tentatively assigned N2-bridged Re-Re dimer. Cyclic voltammetry of the dioxo in the presence of acid indicated the possibility of PCET or PCET-like reactivity and electrolyzing results in a reduction from rhenium(V) to rhenium(I), and the replacement of the two axial oxo ligands, leading to a molecule that is in a better position to fix dinitrogen. This work demonstrates the plausibility of using a rhenium oxo precursor for N2 fixation, opening these stable molecules to investigation.
ECHO CT Head Start on Housing: A Case Study

Year: 2023

description: This thesis is a case study evaluation of Connecticut’s Early Childhood Housing Outreach (ECHO) Head Start on Housing Program, a novel pilot program that identifies housing insecure children in Head Start and Early Head Start schools and connects their families with permanent housing solutions. The thesis examines client and staff experiences with and perceptions of the program in order to assess whether the ECHO pilot is a viable candidate for replication. Data for this case study was gathered by conducting interviews with involved employees from collaborating agencies; real estate agents and landlords who have housed families; Head Start leads who have been instrumental in the identification of clients and facilitation of this program; and, finally, interviews with the families themselves. By combining a thematic qualitative analysis of said subject interviews with descriptive statistics of housed families, this case study will determine challenges in the program and how ECHO can operate more efficiently. This analysis indicates a need for reform in the areas of landlord recruitment and process automation in conjunction with the introduction of federal funding. The thesis finds that with increased funding, outreach, and education efforts towards collaborators, ECHO will continue to serve children and families across the U.S. for years to come.
Outside the Box: Measuring the Unintended Consequences of Ban the Box Policies at an Industry Level
Creators: name: Gravelle, Shane
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: As firms continue struggling through the contemporary labor shortage, traditionally overlooked populations present an opportunity to expand the workforce. Ban the box (BTB) policies have emerged as a popular mechanism to improve ex-offender hiring, in particular, by prohibiting criminal background inquiries on job applications. However, recent research suggests BTB may unintentionally worsen overall employment outcomes for Black and Hispanic men by inviting statistical discrimination. This thesis investigates how BTB-induced discrimination varies across industries. Using the Callaway and Sant’Anna difference estimator, I estimate BTB’s effect on Black and Hispanic shares of hires across nine industries. Overall, BTB improved Black and Hispanic hiring in most industries, though the effect on Black shares often diminished over time. Reductions in hire shares were rare and only observed in customer-facing industries with low entry barriers. This study highlights the importance of considering industry-specific consequences when creating policies to improve ex-offender employment outcomes.

description: Objective: Mood- and stress-related disorders commonly cause attentional and memory impairments in middle-aged individuals. In memory testing, these impairments can be mistakenly interpreted as symptoms of dementia; thus, more reliable diagnostic approaches are needed. The present work defines the discriminant accuracy of the Dementia Apraxia Test (DATE) between psychiatric conditions and early-onset Alzheimer’s disease (AD) on its own and in combination with memory tests. Method: The consecutive sample included 50–70-year-old patients referred to dementia investigations for recent cognitive and/or affective symptoms. The DATE was administered and scored as a blinded measurement, and a receiver operating curve analysis was used to define the optimal diagnostic cut-off score. Results: A total of 24 patients were diagnosed with probable AD (mean age 61 ± 4) and 23 with a psychiatric condition (mean age 57 ± 4). The AD patients showed remarkable limb apraxia, but the psychiatric patients mainly performed at a healthy level on the DATE. The test showed a total discriminant accuracy of 87% for a total sum cut-off of 47 (sensitivity 79% and specificity 96%). The limb subscale alone reached an accuracy of 91% for a cut-off of 20 (sensitivity 83% and specificity 100%). All memory tests were diagnostically less accurate, while the combination of the limb praxis subscale and a verbal episodic memory test suggested a correct diagnosis in all but one patient. Conclusions: Apraxia testing may improve the accuracy of differentiation between AD and psychiatric aetiologies. Its potential in severe and chronic psychiatric conditions should be examined in the future.
Tempo, spazio e memoria in quella «Lunga notte del '43» che non finisce mai di Bassani e Vancini

description: The aim of the article is to explore space, time, and memory in Giorgio Bassani’s short story entitled Lunga notte del’43 [Long Night of ‘43] and in its film adaptation directed by Florestano Vancini. Presenting the reality of the Second World War in Ferrara, Bassani performs a structural analysis in order to examine social reactions to fascism. The novelist’s three expressive categories, la descrizione della vita [the description of life], la narrazione della vita [the narrative of life], and la storicizzazione della vita [the historicization of life], respectively, may also be applied in the interpretation of Vancini’s adaptation. Telling the story of Pino Barilari, an isolated and marginalized pharmacist whose wife has an affair with an anti-fascist, Franco Villani, Lunga notte del’43 constitutes an existential parable of the protagonist’s loneliness. Both in the short story and in the film, Pino’s apartment is a symbolic place, spazio-rifugio [space-refuge], representing illusory protection from the atrocities of fascism. Unlike space, time is explored differently by Bassani and Vancini: the continuum temporalis of the short story is contrasted with the non continuum temporalis of the film. Vancini’s perception of time is evocative of Saint Augustine’s idea of the present of past things, the present of present things, and the present of future things, represented in the film adaptation by Pino’s memories, actual actions, and expectations, respectively. Interestingly enough, oscillating between seemingly unrelated episodes from history and fragments of memory, Vancini’s masterpiece may be regarded as a sort of mosaic.

A Legendre-Gauss Pseudospectral Collocation Method for Trajectory Optimization in Second Order Systems

description: Pseudospectral collocation methods have proven to be powerful tools to solve optimal control problems. While these methods generally assume the dynamics is given in the first order form $\dot{x} = f (x, u, t)$, where x is the state and u is the control vector, robotic systems are typically governed by second order ODEs of the form $\ddot{q} = g(q, \dot{q}, u, t)$, where q is the configuration. To convert the second order ODE into a first order one, the usual approach is to introduce a velocity variable v and impose its coincidence with the time derivative of q. Lobatto methods grant this constraint by construction, as their polynomials describing the trajectory for v are the time derivatives of those for q, but the same cannot be said for the Gauss and Radau methods. This is problematic for such methods, as then they cannot guarantee that $\ddot{q} = g(q, \dot{q}, u, t)$ at the collocation points. On their negative side, Lobatto methods cannot be used to solve initial value problems, as given the values of u at the collocation points they generate an overconstrained system of equations for the states. In this paper, we propose a Legendre-Gauss collocation method that retains the advantages of the usual Lobatto, Gauss, and Radau methods, while avoiding their shortcomings. The collocation scheme we propose is applicable to solve initial value problems, preserves the consistency between the polynomials for v and q, and ensures that $\ddot{q} = g(q, \dot{q}, u, t)$ at the collocation points.

description: Graph partitioning is a fundamental problem in computer science and engineering with diverse applications in fields such as circuit design, network analysis, and data mining [6]. The goal of graph partitioning is to divide a given graph into multiple clusters, with the aim of minimizing certain criteria, such as the number of edges between clusters. Numerous algorithms are available for graph partitioning, ranging from simple heuristics to sophisticated optimization techniques. Due to the NP-hard nature of graph partitioning problems, finding efficient algorithms for large-scale graphs partitioning is crucial. This thesis comprehensively studies existing graph partitioning algorithms, including a recently proposed novel algorithm [1]. The performance of these algorithms is compared in terms of accuracy and timing on various datasets. The accuracy of the partitioning results is compared with the true partitioning groups by using the Normalized Mutual Information (NMI) value and the purity measurement. Additionally, these partitioning algorithms are applied to data from a CyTOF experiment, a significant field in biostatistics. The results demonstrate that the proposed algorithm generally outperforms the spectral partitioning algorithm from k-means in terms of partitioning quality, but it requires more time to converge, resulting in higher computational costs. Overall, the proposed algorithm shows promise for producing improved partitioning results, but further optimization for computational efficiency is needed. This work contributes to the understanding of graph partitioning algorithms and their performance, providing insights for future research in this area.
Le apocalissi del sensibile. Appunti su immagine, disvelamento, rigenerazione

description: Technologies of production and reproduction of sensorial materials (images, sounds, movements or transformations) produce an "apocalypse of the senses", in the double sense that they reveal sensorial life to itself, and that they call for a renewal of sensory routines. From a historical point of view, it is possible to identify three major steps. In the West pre-modern life, sensorial life was made present through images within the category of the sacred, in a profound unity directly involving the subject and the forms of his or her presence. Modernity, in contrast, adopted a secularized view: the sensorium was disrupted and became anonymous, detached from individual bodies and direct experience. Finally, within contemporary “post - media” condition, we consider sensible life as a field of action: indeed, the subject is called to appropriate and manipulate sensible life artificially produced by technology; and the apocalypse of the sensible life becomes a repeated, happy game.

description: Godard's Histoire(s) du cinéma is a film realized using found footages between 1989 and 1998. It celebrates the "end" of the XXI century and of the artistic form which better represented it: cinema. This essay aims to investigate the idea of "apocalypse" as it emerges from the film, in light of Godard's interpretation of such important historical moment.

description: Postmodernism is born from a subtraction, and therefore it couldn’t be a grief to generate the events that lead a character like Bruce Wayne to become a dark beast, a hero without superpowers, whose weakness is being fearless about his own death. Wayne is disguised like a Zorro – Bat and so Bat-Man has chimerical semblance of a manque detectable in a mythographic guilt, that animates the deeds and he is portrayed by a knight with an erotic ride by the tables of Klaus Janson. The crime takes root into madness and in a kind of embodied disease against which hero fights: «How can be explained the return of a pain to remove? There is only a paradoxical way: the removed does not come from the past but it will be in the future», from a promised apocalypse.

description: We compute fragmentation functions for a quark to fragment to a quarkonium through an $S$-wave spin-triplet heavy quark-antiquark pair. We consider both color-singlet and color-octet heavy quark-antiquark ($Q\bar Q$) pairs. We give results for the case in which the fragmenting quark and the quark that is a constituent of the quarkonium have different flavors and for the case in which these quarks have the same flavors. Our results for the sum over all spin polarizations of the $Q\bar Q$ pairs confirm previous results. Our results for longitudinally polarized $Q\bar Q$ pairs agree with previous calculations for the same flavor cases and correct an error in a previous calculation for the different-flavor case.

Improving abnormal cervical cytology care continuum: a program evaluation
Creators: name: Duardo, Jessica
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of Project: The purpose of this project was to complete a program evaluation of the management and follow-up of abnormal cervical cytology of high-grade squamous intraepithelial lesions based on the national guidelines within a large obstetrics and gynecology clinic in northern New Jersey. Formal practice recommendations were developed based on the identified gaps in practice to improve the management of high-grade squamous intraepithelial lesions, patient outcomes, and processes. Methodology: A retrospective chart review of gynecologic patients between the ages of 21-65 who received an initial abnormal cervical cytology finding of high-grade squamous intraepithelial lesions between August 2020 to July 2022 was conducted. Collected data was analyzed using descriptive statistics. Direct observation sessions were also conducted, field notes were analyzed, and a flowchart was created to demonstrate the current workflow for managing high-grade squamous intraepithelial lesions. Formal practice recommendations were developed based on the identified gaps in practice.Results: A total of 12 charts met the inclusion criteria and were reviewed during the retrospective chart review. Provider guideline adherence was 83%, and patient follow-up adherence was 75%. The identified gaps in the current workflow when managing HSIL were related to adequate result notification, scheduling follow-up appointments, and the current reminder and follow-up system. These gaps in the management and follow-up of high-grade squamous intraepithelial lesions reveal an opportunity for improvement.Implications for Practice: Based on the national guidelines, formal practice recommendations were made to improve the management and follow-up of high-grade squamous intraepithelial lesions within the project site. The practice recommendations can improve early detection, successful treatment, and prevent cervical cancer, decreasing mortality rates related to cervical cancer.

description: Although the rutile structure of TiO$_2$ is stable at high temperatures, the conventional quasiharmonic approximation predicts that several acoustic phonons decrease anomalously to zero frequency with thermal expansion, incorrectly predicting a structural collapse at temperatures well below 1000\,K. Inelastic neutron scattering was used to measure the temperature dependence of the phonon density of states (DOS) of rutile TiO$_2$ from 300 to 1373\,K. Surprisingly, these anomalous acoustic phonons were found to increase in frequency with temperature. First-principles calculations showed that with lattice expansion, the potentials for the anomalous acoustic phonons transform from quadratic to quartic, stabilizing the rutile phase at high temperatures. In these modes, the vibrational displacements of adjacent Ti and O atoms cause variations in hybridization of $3d$ electrons of Ti and $2p$ electrons of O atoms. With thermal expansion, the energy variation in this "phonon-tracked hybridization" flattens the bottom of the interatomic potential well between Ti and O atoms, and induces a quarticity in the phonon potential.

description: We give predictions of $\jpsi$ and $\psits$ yields and polarizations in prompt production at hadron colliders based on non-relativistic QCD factorization formula. We calculate short-distance coefficients of all important color-octet intermediate channels as well as color-singlet channels up to $\mathcal{O}(α_S^4)$, i.e. next-to-leading order in $α_S$. For prompt $\jpsi$ production, we also take into account feeddown contributions from $χ_{cJ}$(J=0,1,2) and $\psits$ decays. Color-singlet long-distance matrix elements (LDMEs) are estimated by using potential model, and color-octet LDMEs are extracted by fitting the Tevatron yield data only. The predictions are satisfactory for both yields and polarizations of prompt $\jpsi$ and prompt $\psits$ production at the Tevatron and the LHC. In particular, we find our predictions for polarizations of prompt $\jpsi$ production have only a little difference from our previous predictions for polarizations of direct $\jpsi$ production.
