description: Abstract Background Various health claims about products, remedies, and treatments are everywhere, and many fail to assess these claims. It is therefore important to enable people to think critically about such claims. Oslo Metropolitan University (OsloMet) developed and implemented an educational intervention as a part of a mandatory course in Evidence-Based Health Care (EBHC) for bachelor students in health sciences to increase their critical thinking skills by enabling them to critically assess health claims about treatment effects in the media and make informed choices. A relevant next step is feasibility testing of the EBHC course. Objective This protocol describes the plan of testing and adjusting methods to assess effects of an educational intervention in skills to assess health claims. In particular the assessment methods' feasibility, reliability and validity will be investigated. Feasibility applied to the evaluation tool refers to acceptance by students of a following efficacy trial. Reliability will be investigated in terms unidimensionality of the underpinning construct, while validity refers to the ability of the evaluation tool to detect effect achieved by the training intervention (responsiveness). Participants, methods, and analysis Eligible participants will be bachelor students in health sciences at OsloMet attending the EBHC course. Participants in sub-study 1 and 2 were recruited in 2020/21 and 2021/22. Participants for sub-study 3 and 4 will be recruited during autumn 2022. Both quantitative and qualitative methods will be used to feasibility test the intervention. We will use generalised linear models from cross-sectional surveys and thematic analysis of open-ended questions from cross-sectional surveys and focus group interviews to assess the acceptance of the EBHC course among students (sub-study 1). We will use Rasch analysis to evaluate the psychometric properties of the questionnaires from cross-sectional surveys (sub-study 2 and 3). Generalised linear models will be used to estimate learning outcome from uncontrolled before-after studies (sub-study 4). Ethical considerations The studies to be carried out in 2022 were approved by the Norwegian Centre for Research Data (NSD) on 28 July 2022 (Reference number 935258).

description: This study aims to capture the complex clinical reasoning process during tailoring of exercise and dietary interventions to adverse effects and comorbidities of patients with ovarian cancer receiving chemotherapy. Clinical vignettes were presented to expert physical therapists (n = 4) and dietitians (n = 3). Using the think aloud method, these experts were asked to verbalize their clinical reasoning on how they would tailor the intervention to adverse effects of ovarian cancer and its treatment and comorbidities. Clinical reasoning steps were categorized in questions raised to obtain additional information; anticipated answers; and actions to be taken. Questions and actions were labeled according to the evidence-based practice model. Questions to obtain additional information were frequently related to the patients’ capacities, safety or the etiology of health issues. Various hypothetical answers were proposed which led to different actions. Suggested actions by the experts included extensive monitoring of symptoms and parameters, specific adaptations to the exercise protocol and dietary-related patient education. Our study obtained insight into the complex process of clinical reasoning, in which a variety of patient-related variables are used to tailor interventions. This insight can be useful for description and fidelity assessment of interventions and training of healthcare professionals. The delivery of exercise and dietary programs is not a one-size fits all approach but involves a complex clinical reasoning process. Therefore, protocols should not only describe the intervention content, but also the strategy on how to tailor the intervention to individual adverse effects and pre-existing comorbidities. Education of healthcare professionals delivering the intervention is important as these professionals need to have good clinical reasoning skills to adequately tailor the intervention.

description: The existence of a spatially thin, kinematically coherent Disk of Satellites (DoS) around the Milky Way (MW), is a problem that often garners vivacious debate in the literature or at scientific meetings. One of the most recent incarnations of this wrangle occurred with two papers by Maji et al, who argued that these structures "maybe a misinterpretation of the data". These claims are in stark contrast to previous works. Motivated by this and other recent publications on this problem, we discuss necessary considerations to make, observational effects to consider, and pitfalls to avoid when investigating satellite galaxy planes such as the MW's DoS. In particular, we emphasize that conclusions need to have a statistical basis including a determination of the significance of satellite alignments, observational biases must not be ignored, and measurement errors (e.g. for proper motions) need to be considered. We discuss general problems faced by attempts to determine the dynamical stability of the DoS via orbit integrations of MW satellite galaxies, and demonstrate that to interpret simulations, it is helpful to compare them with a null case of isotropically distributed satellite positions and velocities. Based on these criteria, we find that the conclusions of Maji et al. do not hold up to scrutiny, and that their hydrodynamic cosmological simulation of a single host shows no evidence for a significant kinematic coherence among the simulated satellite galaxies, in contrast to the observed MW system.

description: In this article we study the large $N$ asymptotics of complex moments of the absolute value of the characteristic polynomial of a $N\times N$ complex Ginibre random matrix with the characteristic polynomial evaluated at a point in the unit disk. More precisely, we calculate the large $N$ asymptotics of $\mathbb{E}|\det(G_N-z)|^γ$, where $G_N$ is a $N\times N$ matrix whose entries are i.i.d and distributed as $N^{-1/2}Z$, $Z$ being a standard complex Gaussian, $\mathrm{Re}(γ)>-2$, and $|z|<1$. This expectation is proportional to the determinant of a complex moment matrix with a symbol which is supported in the whole complex plane and has a Fisher-Hartwig type of singularity: $\det(\int_\mathbb{C} w^{i}\overline{w}^j |w-z|^γe^{-N|w|^{2}}d^2 w)_{i,j=0}^{N-1}$. We study the asymptotics of this determinant using recent results due to Lee and Yang concerning the asymptotics of orthogonal polynomials with respect to the weight $|w-z|^γe^{-N|w|^2}d^2 w$ along with differential identities familiar from the study of asymptotics of Toeplitz and Hankel determinants with Fisher-Hartwig singularities. To our knowledge, even in the case of one singularity, the asymptotics of the determinant of such a moment matrix whose symbol has support in a two-dimensional set and a Fisher-Hartwig singularity, have been previously unknown.

description: The main aim of this paper is to set first the steps for the dynamic analysis of circular cable suspended roofs by minimizing the global dynamic potential energy (TPDE) using the conjugate gradient method (CGM). This method is advantageous that it takes the nonlinearity in behavior of cable systems into account. Also, it is applicable for structures with large number of degrees of freedom using the computer systems. Finally, it is valid for both static and dynamic analysis of cable systems. The second author constructed all computer programs that be used in the static and dynamic analysis for all required examples. Many circular cable roofs have been analyzed using a computer program based upon the above method of analysis. The results were used in following the dynamic behavior of circular cable suspended roofs.

description: We report on the possibility to simultaneously generate in graphene a {\it bulk valley-polarized dissipative transport} and a {\it quantum valley Hall effect} by combining strain-induced gauge fields and real magnetic fields. Such unique phenomenon results from a resonance/anti-resonance effect driven by the superposition/cancellation of superimposed gauge fields which differently affect time reversal symmetry. The onset of a valley-polarized Hall current concomitant to a dissipative valley-polarized current flow in the opposite valley is revealed by a $e^2/h$ Hall conductivity plateau. We employ efficient linear scaling Kubo transport methods combined with a valley projection scheme to access valley-dependent conductivities and show that the results are robust against disorder.

This was a qualitative study adopting a constructivist grounded theory approach. Nineteen health professionals participated in the pilot test of the digital self-monitoring solution BackTrace. Data were collected cross-sectionally and consisted of: (a) audio recordings from focus groups with health professionals, (b) field notes from participant observation of online meetings with health professionals, (c) field notes from participant observations of consultations between health professionals and individuals with low back pain and (d) audio recordings from workshops with health professionals. Two main themes and one sub-theme were identified, describing how BackTrace enabled more focused consulting practices, supported patient-self management and improved the relationship between individuals with low back pain and health professionals. Barriers were identified describing how the implementation of digital health solutions required a change in workflow, resources and culture - as well as management support. Findings indicated a need for a change at the system level, including a changed view of digitisation in healthcare systems containing a more supporting approach.

description: Timings of human activities are marked by circadian clocks which in turn are entrained to different environmental signals. In an urban environment the presence of artificial lighting and various social cues tend to disrupt the natural entrainment with the sunlight. However, it is not completely understood to what extent this is the case. Here we exploit the large-scale data analysis techniques to study the mobile phone calling activity of people in large cities to infer the dynamics of urban daily rhythms. From the calling patterns of about 1,000,000 users spread over different cities but lying inside the same time-zone, we show that the onset and termination of the calling activity synchronizes with the east-west progression of the sun. We also find that the onset and termination of the calling activity of users follows a yearly dynamics, varying across seasons, and that its timings are entrained to solar midnight. Furthermore, we show that the average mid-sleep time of people living in urban areas depends on the age and gender of each cohort as a result of biological and social factors.

description: Emergency and disaster management planning is an emerging role with limited practical guidance on how it should be implemented by community, disability, health and rehabilitation service providers. This study examined the emergency preparedness of service providers and how they viewed their role and contributions to disaster risk reduction, including their capacity and willingness to facilitate preparedness planning with their clients. A questionnaire was developed and administered nationally. Descriptive statistics, multivariate regression analyses, and thematic analysis of open-ended questions provide insight on the knowledge, tools and training needs of service providers to contribute to preparedness of themselves and the people they support. Facilitating emergency preparedness with people with disability was strongly associated with a high level of mental preparedness, household preparedness scores, and completion of Person-Centred Emergency Preparedness (P-CEP) training. Perceived lack of funding, insufficient tools, and exclusion of emergency planning from job descriptions were negatively associated with facilitating emergency preparedness with clients. Study findings lay the groundwork for development of the role and capabilities of individual service providers including the need to equip disability, health and rehabilitation service providers with training and tools to prepare themselves and the people they support for emergencies. Participation in emergency training such as psychological first aid, evacuation drills, and Person-Centred Emergency Preparedness (P-CEP) can increase the personal preparedness of service providers.Rehabilitation professionals are advised to develop their capabilities in emergency preparedness before facilitating emergency planning with their clients.Rehabilitation professionals should connect with their local emergency services to learn about disaster risks and preparedness actions they can take to increase personal emergency preparedness for themselves and their clients.

description: This study examined Teachers effectiveness strategies and students' attitude to learning in Public Secondary Schools in Akwa Ibom State, Nigeria. Three research questions and three hypotheses were formulated to guide the study. A correlational research design was used for the purpose of the study. The population of the study comprised of 994,297 students for the 2020/2021 academic session in 242 public secondary schools. The sample size was five hundred and twenty (520) students selected using multistage random technique. The instruments used for data collection were Teacher Effectiveness Strategies Questionnaire (TESQ) and Students' Attitude to Learning Questionnaire (SATLQ). The TESQ had 15-items related to teachers' classroom planning, teachers' classroom instruction and teacher's classroom interpersonal relations while the SATLQ had 10-items related to students' attitude to learning. The instruments were subjected to face and content validation by six (6) experts while the reliability coefficient of the instruments stood at 0.82 and 0.72 respectively. The reliability was determined using Cronbach alpha reliability method. The data collected were analyzed using Simple Linear Correlation Statistical Tool at .05 alpha level of significance. The result showed that teachers' classroom planning, teachers' classroom instruction and teacher's classroom interpersonal relations predicted students' attitude to learning significantly. Consequently, it was recommended among others that government should be very careful on teacher's recruitment, retraining and improvisation of infrastructures and instructional materials for sustainable education system in Nigeria. Student-teachers and teacher's student inter-personal relations should be cordial and teachers passionate about the student's future, love and protect the teaching profession as well.

Application of 1H HR-MAS-NMR spectroscopy in spatial tissue metabolic profiling
Creators: name: Vonhof, Elisabeth Viola
Publisher: name: Imperial College London
Year: 2022

description: HR-MAS-NMR of intact tissue biopsies is a well-established method resulting in one NMR spectrum per whole biopsy showing all detectable metabolites at once. The aim of this project was to explore the possibility and usefulness of monitoring specific locations within the biopsy using HR-MAS-NMR. Firstly, the method was applied to a classic toxicology situation. Many drug development compounds fail because of preclinical animal liver toxicity conventionally detected using histology. Usually, only one of the murine liver lobes is used for this and is assumed to be representative of the whole organ. In this work, a metabolic variation across murine liver lobes has been investigated via a set of biopsies across all lobes. Using HR-MAS-NMR spectra analysed by various types of multivariate analysis, no lobe-specific metabolic variation could be found, confirming the general validity of the representative lobe approach. To increase location specificity, a spatially-resolved NMR pulse sequence (slice local- ized spectroscopy (SLS)) was modified and its respective effectiveness was explored. The pulse sequence was first validated using artificially created samples (phantoms), and practical examples were layered fruit separated by paraffin film and milled phantoms produced from materials which were magnetic-susceptibility-matched to the HR-MAS rotor. The HR-MAS SLS sequence was then applied to a mixed mouse renal tissue biopsy, and renal cortex and medulla successfully assigned to individual slices from spatially-resolved spectra using pure cortex and medulla reference HR-MAS-NMR spectra and orthogonal projection to latent structures discriminant analysis (OPLS-DA) to establish metabolic markers differentiating the two. Together, this work shows the potential of HR-MAS-NMR as applied to tissue biopsies. Particularly, spatially-resolved methods hold potential for improved biochemical and mechanistic understanding and the methodology could be expanded to applications in many areas of biomedical relevance.

description: It is demonstrated that, in the framework of the orbit method, a simple and damped harmonic oscillators are indistinguishable at the level of an abstract Lie algebra. This opens a possibility for treating the dissipative systems within the orbit method. In depth analysis of the coadjoint orbits of the $(1+1)$ dimensional Newton-Hooke group are presented. Further, it is argued that the physical interpretation is carried by a specific realisation of the Lie algebra of smooth functions on a phase space rather than by an abstract Lie algebra.

description: Recently, the basic concept of quantum coherence (or superposition) has gained a lot of renewed attention, after Baumgratz et al. [PRL 113:140401 (2014)], following Åberg [arXiv:quant-ph/0612146], have proposed a resource theoretic approach to quantify it. This has resulted in a large number of papers and preprints exploring various coherence monotones, and debating possible forms for the resource theory. Here we take the view that the operational foundation of coherence in a state, be it quantum or otherwise wave mechanical, lies in the observation of interference effects. Our approach here is to consider an idealised multi-path interferometer, with a suitable detector, in such a way that the visibility of the interference pattern provides a quantitative expression of the amount of coherence in a given probe state. We present a general framework of deriving coherence measures from visibility, and demonstrate it by analysing several concrete visibility parameters, recovering some known coherence measures and obtaining some new ones.

description: The Injustice Experience Questionnaire (IEQ) gauges the extent to which individuals with chronic pain perceive feelings of injustice concerning their pain. The study’s objective was to assess the feasibility, absolute and relative reliability, as well as the convergent and construct validity of the Greek version of the IEQ. A cross-cultural adaptation of the IEQ in Greek was carried out according to the published guidelines. Ninety patients with chronic pain and 44 healthy participants completed the IEQ-GR, the Pain Catastrophizing Scale (PCS), and the Hospital Anxiety and Depression Scale (HADS). A subset of 36 volunteers completed the IEQ-GR twice over 1 week. The ICC was calculated at 0.98 for IEQ-total and 0.83–0.96 for all items. The Cronbach’s a was estimated at 0.98 for IEQ-total and 0.91–0.98 for all items. The SEM ranged from 0.20 to 1.63 and the SDC was 0.36–2.62 for all items. Positive and significant correlations between IEQ-GR and PCS (r = 0.59, p < 0.01), HADS (r = 0.58, p < 0.01), HADS depression (r = 0.50, p < 0.01), and HADS anxiety (r = 0.55, p < 0.01), were found. There was a statistically significant difference in IEQ between the patient and control groups. The IEQ-GR demonstrated excellent reliability, internal consistency, convergent and discriminant validity in a Greek population. Perceived Injustice (PI) poses a risk factor for treatment ineffectiveness, significantly impacting disability and return-to-work outcomes. The Injustice Experience Questionnaire (IEQ) is a dependable tool for evaluating perceived injustice in individuals with chronic pain. This study demonstrates the reliability and validation of the Greek version of the IEQ (IEQ-GR) for assessing chronic pain patients’ perceived injustice. Assessing and identifying patients experiencing PI, followed by individualized management, can aid in their rehabilitation and prevent inappropriate interventions.

description: Deploying unmanned aerial vehicles (UAVs) as aerial base stations (BSs) in order to assist terrestrial connectivity, has drawn significant attention in recent years. UAV-BSs can take over quickly as service providers during natural disasters and many other emergency situations when ground BSs fail in an unanticipated manner. UAV-BSs can also provide cost-effective Internet connection to users who are out of infrastructure. UAV-BSs benefit from their mobility nature that enables them to change their 3D locations if the demand of ground users changes. In order to effectively make use of the mobility of UAV-BSs in a dynamic network and maximize the performance, the 3D location of UAV-BSs should be continuously optimized. However, solving the location optimization problem of UAV-BSs is NP-hard with no optimal solution in polynomial time for which near optimal solutions have to be exploited. Besides the conventional solutions, i.e. heuristic solutions, machine learning (ML), specifically reinforcement learning (RL), has emerged as a promising solution for tackling the positioning problem of UAV-BSs. The common practice for optimizing the 3D location of UAV-BSs using RL algorithms is assuming fixed location of ground users (i.e., UEs) in addition to defining discrete and limited action space for the agent of RL. In this thesis, we focus on improving the location optimization of UAV-BSs in two ways: 1-Taking into account the mobility of users in the design of RL algorithm, 2-Extending the action space of RL to a continuous action space so that the UAV-BS agent can flexibly change its location by any distance (limited by the maximum speed of UAV-BS). Three types of RL algorithms, i.e. Q-learning (QL), deep Q-learning (DQL) and actor-critic deep Q-learning (ACDQL) have been employed in this thesis to step-by-step improve the performance results of a UAV-assisted cellular network. QL is the first type of RL algorithm we use for the autonomous movement of the UAV-BS in the presence of mobile users. As a solution to the limitations of QL, we next propose a DQL-based strategy for the location optimization of the UAV-BS which largely improves the performance results of the network compared to the QL-based model. Third, we propose an ACDQL-based solution for autonomously moving the UAV-BS in a continuous action space wherein the performance results significantly outperforms both QL and DQL strategies.

description: Magic trapping of ground and Rydberg states, which equalizes the AC Stark shifts of these two levels, enables increased ground-to-Rydberg state coherence times. We measure via photon storage and retrieval how the ground-to-Rydberg state coherence depends on trap wavelength for two different traps and find different optimal wavelengths for a one-dimensional optical lattice trap and a running wave optical dipole trap. Comparison to theory reveals that this is caused by the Rydberg electron sampling different potential landscapes. The observed difference increases for higher principal quantum numbers, where the extent of the Rydberg electron wave function becomes larger than the optical lattice period. Our analysis shows that optimal magic trapping conditions depend on the trap geometry, in particular for optical lattices and tweezers.

description: Vertically stacked atomic layers from different layered crystals can be held together by van der Waals forces, which can be used for building novel heterostructures, offering a platform for developing a new generation of atomically thin, transparent and flexible devices. The performance of these devices is critically dependent on the layer thickness and the interlayer electronic coupling, influencing the hybridisation of the electronic states as well as charge and energy transfer between the layers. The electronic coupling is affected by the relative orientation of the layers as well as by the cleanliness of their interfaces. Here, we demonstrate an efficient method for monitoring interlayer coupling in heterostructures made from transition metal dichalcogenides using photoluminescence imaging in a bright-field optical microscope. The colour and brightness in such images are used here to identify mono- and few-layer crystals, and to track changes in the interlayer coupling and the emergence of interlayer excitons after thermal annealing in mechanically exfoliated flakes as well as a function of the twist angle in atomic layers grown by chemical vapour deposition. Material and crystal thickness sensitivity of the presented imaging technique makes it a powerful tool for characterisation of van der Waals heterostructures assembled by a wide variety of methods, using combinations of materials obtained through mechanical or chemical exfoliation and crystal growth.

description: Intrinsic alignments of galaxies are a significant astrophysical systematic affecting cosmological constraints from weak gravitational lensing. Obtaining numerical predictions from hydrodynamical simulations of expected survey volumes is expensive, and a cheaper alternative relies on populating large dark matter-only simulations with accurate models of alignments calibrated on smaller hydrodynamical runs. This requires connecting the shapes and orientations of galaxies to those of dark matter haloes and to the large-scale structure. In this paper, we characterise galaxy-halo alignments in the Horizon-AGN cosmological hydrodynamical simulation. We compare the shapes and orientations of galaxies in the redshift range $0

description: The Functional Ambulation Categories (FAC) is a measurement tool used to classify walking ability according to the amount of physical support required. In this study, the FAC is translated into Danish and the reliability and validity of the FAC are established in a population of patients with acquired brain injury (ABI). The study took place in a neuro-rehabilitation setting. The translation process followed an accepted forward–backward translation method in six steps. For the assessment of clinometric properties a cross-sectional study design was applied. Interrater reliability was assessed with weighted Cohen’s kappa. Construct validity of the FAC was assessed with Spearman’s rho by correlating the FAC to walking velocity assessed with the 10-meter walk test and to the number of daily steps assessed with accelerometers. The FAC was successfully translated into Danish. For the assessment of clinometric properties, 53 patients were included. Almost perfect interrater reliability was found (κ = 0.92, p < 0.0001). Construct validity was high between FAC and walking velocity (r2 = 0.87, p < 0.0001) and moderate between FAC and the number of daily steps (r2 = 0.62, p < 0.0001). The Danish version of the FAC was found reliable and valid for use in-patients with ABI. The Functional Ambulation Categories (FAC) has been translated into Danish and is available for use by researchers and clinicians in Denmark. Steps to ensure high reliability are described and can be replicated in other settings and these steps include developing a practice scoring sheet with a patient case for each FAC score. The reliability and validity of the FAC have been established, and the results are generalizable to similar populations of patients with acquired brain injury.

description: This work presents an agent-based simulation (ABS) of the active learning process in an Electrical Engineering course. In order to generate input data to the simulation, an active learning methodology developed especially for part-time degree courses, called Project-Based Learning Agile (PBLA), has been proposed and implemented at the Regional University of Blumenau (FURB), Brazil. Through the analysis of survey responses obtained over five consecutive semesters, using partial least squares path modeling (PLS-PM), it was possible to generate data parameters to use as an input in a hybrid kind of agent-based simulation known as PLS agent. The simulation of the scenario suggests that the learning occur faster when the student has higher levels of humanist's aspects as self-esteem, self-realization and cooperation.

description: The circumgalactic medium (CGM) is a complex and multiphase region of gas that surrounds galaxies. Analysing the physical properties of this gas is difficult as the models we use only provide us with estimations of these properties. Furthermore, there is a struggle to build a picture of how the properties change based on the halo mass of the CGM. We have analysed simulations from Auriga, a suite of magento-hydrodynamical zoom-in simulations, to build this picture of how the physical properties of the CGM change with halo mass. Focusing our work on three properties temperature, density and metallicity. This also led to an investigation into the column density of HI, CIV, OVI, SiII and MgII in Auriga models with a comparison between our results and observations. We find that the temperature and density of the CGM increase with halo mass in both average and one sigma scatter. This indicates that the multiphase nature of the CGM is dependent on halo mass, as we see a greater distribution of temperature and density in larger mass halos than in smaller ones.
 From our column density investigation, our results match well across all masses for HI and in larger Milky Way mass halos for the warm regime (CIV and OVI) and the cool regime (SiII and MgII) when compared to observations observations. We see that as the mass decreases, our results are significantly lower than observational results. This could be due to lower temperatures in these halos and therefore OVI and CIV aren't as present.

description: This review investigated the effectiveness of adjuvant therapy combined with constraint-induced movement therapy (CIMT) in improving the paretic upper limb functionality in adults with stroke sequelae during the subacute to chronic rehabilitation phase. In this systematic review and meta-analysis of randomized controlled trials (RCT), electronic databases, including PubMed, Web of Science, CINAHL, and MEDLINE, were searched. We included RCTs that investigated the outcomes of adjuvant therapy (i.e. other therapies) added to CIMT compared with CIMT alone. Key trial findings were qualitatively synthesized and analyzed. This meta-analysis examined variables, such as mean scores and standard deviations, using the following outcome measures: Fugl-Meyer Assessment (FMA) upper limb items, Action Research Arm Test (ARAT), Amount of Use (AOU) of Motor Activity Log (MAL), and Quality of Movement (QOM) of MAL. Eighteen eligible RCTs were included in the analysis. Adding CIMT to adjunctive therapy significantly improved FMA compared with CIMT alone (mean difference [MD] 4.02, 95% confidence interval [CI] 2.60–5.44; I2 = 85%; 15 studies; 330 participants). Similarly, the ARAT and MAL-AOU scores improved significantly. CIMT combined with several adjunctive therapies effectively improved upper limb function. In recent years, clinical trials combining other therapies with Constraint-induced movement therapy (CIMT) have become increasingly common.This study shows that combining CIMT with adjuvant therapy improves upper limb function.Different protocols of the CIMT in each study could be factor that impacted the results of Motor Activity Log.In clinical practice, the findings of this study into their treatment protocols to improve patient outcomes and ensure the effective application of evidence-based rehabilitation strategies.

description: We perform threshold resummation of soft gluon corrections to the total cross section and the invariant mass distribution for the process $pp \to t\bar{t}H$. The resummation is carried out at next-to-next-to-leading-logarithmic (NNLL) accuracy using the direct QCD Mellin space technique in the three-particle invariant mass kinematics. After presenting analytical expressions we discuss the impact of resummation on the numerical predictions for the associated Higgs boson production with top quarks at the LHC. We find that NLO+NNLL resummation leads to predictions for which the central values are remarkably stable with respect to scale variation and for which theoretical uncertainties are reduced in comparison to NLO predictions.
