description: Intensity mapping is a promising technique for surveying the large scale structure of our Universe from $z=0$ to $z \sim 150$, using the brightness temperature field of spectral lines to directly observe previously unexplored portions of out cosmic timeline. Examples of targeted lines include the $21\,\textrm{cm}$ hyperfine transition of neutral hydrogen, rotational lines of carbon monoxide, and fine structure lines of singly ionized carbon. Recent efforts have focused on detections of the power spectrum of spatial fluctuations, but have been hindered by systematics such as foreground contamination. This has motivated the decomposition of data into Fourier modes perpendicular and parallel to the line-of-sight, which has been shown to be a particularly powerful way to diagnose systematics. However, such a method is well-defined only in the limit of a narrow-field, flat-sky approximation. This limits the sensitivity of intensity mapping experiments, as it means that wide surveys must be separately analyzed as a patchwork of smaller fields. In this paper, we develop a framework for analyzing intensity mapping data in a spherical Fourier-Bessel basis, which incorporates curved sky effects without difficulty. We use our framework to generalize a number of techniques in intensity mapping data analysis from the flat sky to the curved sky. These include visibility-based estimators for the power spectrum, treatments of interloper lines, and the "foreground wedge" signature of spectrally smooth foregrounds.

Assessment of the Cause of Death and Characteristics of Chronic Illnesses in Addis Ababa With Emphasis on HIV/Aids a Community Based Study
Creators: name: Belete, Habtamu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2005

description: Background: Information on causes of adult deaths is relatively scarce in developing countries where vital registration systems are often incomplete or nonexistent and many deaths occur at home. Objective: To obtain a community based estimate of the specific causes of mortality and the burden of chronic morbidity in an urban adult population with major emphasis on determining the pattern of HIV/AIDS mortality in Addis Ababa. Method: A cross sectional quantitative study was done from Dec. 2004-Jan. 2005 on 3600 randomly selected households in Addis Ababa. An appropriate VA tool and chronic morbidity assessment questionnaire were utilized for data collection. Results: The crude death rate was 8.1 per 1000 population per year. The cause specific mortality fraction of AIDS/TB , noncommunicable disease and accidents were 44.3%, 15.3% and 11.2% respectively. Age and sex specific mortality picture of AIDS showed that at early adult age (20-29) years, females exhibited a very high death rate than their male counterpart, which is high at 29-34 years of age Seventy five percent of deaths were found to have occurred at home with health institution deaths accounting for only 21%. Hypertension, asthma, cardiac problem and psychiatric illnesses were the commonest chronic illnesses identified during the study. AIDS mortality fraction is still higher as compared to other causes of deaths in Addis Ababa. The burden of AIDS mortality is higher in the center of the city where socio-economic status is low and prostitution and sex marketing is high as compared to the outer city. Conclusion and Recommendation: The proportional mortality due to AIDS is high as compared to other causes of deaths in Addis Ababa. At early adult age females exhibited higher AIDS specific mortality rate than males for which it is high at later age. Chronic non- communicable diseases are also posing significant health problems in terms of chronic morbidity and mortality in the city. Continuation of such community-based surveillance of cause of deaths is recommended.

description: The central goal of jet quenching studies in high-energy nuclear collisions is the characterization of those QCD medium properties that are accessible by these probes. Most of the discussion in the last years has been focused on the determination of the jet quenching parameter, $\hat q$. We present here an extraction of this parameter using data of inclusive particle suppression at RHIC and LHC energies for different centralities. Our approach consists of fitting a $K$ factor that quantifies the departure of this parameter from an ideal estimate, $K\equiv \hat q/(2ε^{3/4})$, where $\hat q$ is determined by the local medium quantities as provided by hydrodynamical calculations. We find that this $K$ factor is larger at RHIC than at the LHC, as obtained already in previous analyses, but, surprisingly, it is almost independent of the centrality of the collision. Taken at face value, the $K$ factor would not depend on the local properties of the medium as energy density or temperature, but on global collision quantities such as the center of mass energy. This is a very intriguing, unexpected possibility for which we cannot yet provide a clear interpretation. We also comment on the limitations of the formalism that may affect this conclusion.

description: We suggest the possibility of a linear magnetochiral effect in time reversal breaking Weyl semimetals. Generically the magnetochiral effect consists in a simultaneous linear dependence of the magnetotransport coefficients with the magnetic field and a momentum vector. This simultaneous dependence is allowed by the Onsager reciprocity relations, being the separation vector between the Weyl nodes the vector that plays such role. As a side consequence, we find a non vanishing positive longitudinal magnetoconductivity at Fermi energies above the point where the chirality of the Weyl nodes is globally lost.

description: Space charge accumulation within GEM holes is one of the vital phenomena which affects many of the key working parameters of the detector. This accumulation is found to be significantly affected by the initial primary charge configurations and applied GEM voltages since they determine charge sharing and the subsequent evolution of detector response. In this work, we have studied the effects of space charge phenomena on different parameters for single GEM detectors using a hybrid numerical model.

description: Despite the immense technology advancement in the surgeries the criteria of assessing the surgical skills still remains based on subjective standards. With the advent of robotic-assisted surgery, new opportunities for objective and autonomous skill assessment is introduced. Previous works in this area are mostly based on structured-based method such as Hidden Markov Model (HMM) which need enormous pre-processing. In this study, in contrast with them, we develop a new shaped-based framework for automatically skill assessment and personalized surgical training with minimum parameter tuning. Our work has addressed main aspects of skill evaluation; develop gesture recognition model directly on temporal kinematic signal of robotic-assisted surgery, and build automated personalized RMIS gesture training framework which . We showed that our method, with an average accuracy of 82% for suturing, 70% for needle passing and 85% for knot tying, performs better or equal than the state-of-the-art methods, while simultaneously needs minimum pre-processing, parameter tuning and provides surgeons with online feedback for their performance during training.

description: Dynamical reweighting methods permit to estimate kinetic observables of a stochastic process governed by a target potential $\tilde{V}(x)$ from trajectories that have been generated at a different potential $V(x)$. In this article, we present Girsanov reweighting and Square Root Approximation (SqRA): the first method reweights path probabilities exploiting the Girsanov theorem and can be applied to Markov State Models (MSMs) to reweight transition probabilities; the second method was originally developed to discretize the Fokker-Planck operator into a transition rate matrix, but here we implement it into a reweighting scheme for transition rates. We begin by reviewing the theoretical background of the methods, then present two applications relevant to Molecular Dynamics (MD), highlighting their strengths and weaknesses.

Antiretroviral Treatment Adherence and its Correlates among People Living with HIV/AIDS on Highly Active Antiretroviral Therapy in Addis Ababa, Ethiopia
Creators: name: Tadios, Yonas
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2005

description: Background: The introduction of HAART has transformed HIV infection into a chronic manageable disease. The key to this success is the ability and willingness of HIV-positive individuals to adhere to HAART regimens. But at present little is known about the patient's experience and adherence when taking such complex regimens. Objective: To assess the degree of adherence with antiretroviral therapy, identify which factors influence it, and describe the everyday experience of PLWHA on ARV therapy. Design and setting: We used a combination of methodologies, including questionnaires, interviews and medical record review with patients in selected hospitals. Patients and methods: For in-depth interviews, we purposively sampled 10 PLWHA. After screening for HIV- dementia each participated in an audio taped interview with the investigator. In the cross - sectional survey, consecutive HIV-infected patients at three ART centers in Addis Ababa were invited. Data on drug adherence were collected using patient self-report and depression was measured using Beck's depression inventory (BDI). Clinical data were recorded by asking the patient and reviewing their chart. Knowledge about ART was assessed by questions presented in "Yes" or "No" format. Results: A total of 431 HIV infected patients responded to the survey questionnaire. 81.2% of patients were adherent by self report in the week before the assessment. The major reasons reported for non-adherence were, being too busy with other things or simply forgot (33.9%) and being away from home (27.5%). Correlates of adherence in the multivariate analysis controlling for sociodemographic differences were: having regular follow-up, not being depressed, having no side effects, fitting a regimen to the daily routine, being satisfied with the relationship with health care providers, and the perception that doctors were capable and had access to assistance and reliable pharmacy. Conclusions: The self-reported adherence rate in our study was higher than that seen in developed countries. Programs and clinical efforts to improve medication taking in the study setups should strive to: provide regular follow up for patients, manage depression with a multidisciplinary approach, increase patients' awareness of the side effects of ARVs and possible remedies, integrate medications better into patients' daily routines, improve patients' confidence, trust and satisfaction with their caregivers, eliminate problems of access, and alleviate the impact of cost

description: HIV infection is the greatest known risk factors for the development of active tuberculosis in individuals latently infected with tuberculosis, and there is now strong evidence for the efficacy of prophylaxis treatment in the prevention of TB in HIV infected individuals. Implementation of Isoniazid PT in developing country presents several problems; therefore this study tried to assess the IPT program implemented in the ENARP sites and its applicability in other VCT centers. The objective of this study was to evaluating operational aspect of INH prophylaxis program for Human immuno-deficiency virus positive patients in the ENARP sites. A crossectional study supplemented with review of available cohort data was conducted. All HIV positive cohort participants, in the two ENARP sites, were included Of 132 HIV positive participants 61(21.6%) were selected for INH prophylaxis program based on CD4 count who had less than 350 cell/mm3. Among 71(53.8%) participants who were not included in the IPT program, 13(18.3%) died, 37(52.1%) subjects were excluded due to their CD4 count, 13(18.3%) due to recent TB treatment history and 5(7.04%) refused to participate in the IPT program. TST were done to identify the most benefited with IPT, 44.3% were anergic and 26.2% were positive. Of 61 participant 57.4% were completed PT, 24.6% discontinued and 7(11.5%) subjects were on treatment during data collection. The study uptake looks appropriate in that the risk of having TB increases with the CD4 count less than 350 cell/mm3, OR=1.12,95% CI (1.06-1.28) .TST induration size had significant correlation with CD4 count using linear regression model and Pearson correlation analysis. Except 9.8% the rest 84.4% got health care support from the project to enhance adherence, 92.8% were agree on that ENARP staffs has good patient approach. And 86.6% were appreciate the service given to them and recommend to others. Of 61 participants 19(31.1%) missed scheduled appointment. Among 32 who completed 5(15.6%) of them missed ingesting daily pills only for a day. And INH metabolites test were positive in 80.4% of study subjects. IPT doesn't have effect on CD4 count and weight using Wilcoxon sign rank test. Ninety-three point seven of the cost of the program spent before the patient starts PT. The benefit due to PT exceeded the cost of the program by 4.99 factors. Study uptake looks appropriate, screening for active TB was performed as it was recommend by WHO. Even though different methods used to select those most benefited, it needs further evaluation. Adherence to treatment in the project favorably compares with other similar study. Therefore the project has shown the feasibility of IPT in our context.

description: We build a supersymmetric version with $SU(3)_C\otimes SU(2)_L\otimes U(1)_{Y^\prime}\otimes U(1)_{B-L}$ gauge symmetry, where $Y^\prime$ is a new charge and $B$ and $L$ are the usual baryonic and leptonic numbers. The model has three right-handed neutrinos with identical $B-L$ charges, and can accommodate all fermion masses at the tree level. In particular, the type-I seesaw mechanism is implemented for the generation of the active neutrino masses. We obtain the mass spectra of all sectors and for the scalar one we also give the flat directions allowed by the model.

description: Flexibility for interface engineering, and access to all-optical switching of the magnetization, make synthetic ferrimagnets an interesting candidate for advanced opto-spintronic devices. Moreover, due to their layered structure and disordered interfaces they also bear promise for the emerging field of graded magnetic materials. The fastest and most efficient spin-orbit torque driven manipulation of the magnetic order in this material system generally takes place at compensation. Here, we present a systematic experimental and modeling study of the conditions for magnetization compensation and perpendicular magnetic anisotropy in the synthetic ferrimagnetic Co/Gd/Co/Gd system. A model based on partial intermixing at the Co/Gd interfaces of this system has been developed which explains the experiments well, and provides a new tool to understand its magnetic characteristics. More specifically, this work provides new insight in the decay of the Co proximity-induced magnetization in the Gd, and the role the capping layer plays in the Gd magnetization.

description: We perform a re-analysis of Belle data for the transverse $Λ$ and $\barΛ$ polarization in $e^+ e^-$ annihilation processes within a transverse momentum dependent (TMD) factorization approach. We consider two data sets, one referring to the associated production of $Λ$'s with a light unpolarized hadron in an almost back-to-back configuration, and one for the inclusive $Λ$ production, with the reconstruction of the thrust axis. We adopt the Collins-Soper-Sterman framework and employ the recent formulation on the factorization of single-inclusive hadron production. This extends a previous phenomenological study carried out in a more simplified TMD approach, leading to a new extraction of the polarizing fragmentation function (FF). While confirming several features of the previous analysis, here we include the proper QCD scale dependence of this TMD FF and carefully exploit the role of its nonperturbative component. The compatibility, within a unique TMD factorization scheme, of double and single-inclusive hadron production is discussed in detail. Moreover, we consider another data set for inclusive $Λ$ production, at much larger energies, from the OPAL Collaboration, in order to test the consistency of the entire approach. Finally, we elaborate on some fundamental issues like the role of $SU(2)$ isospin symmetry and the heavy quark contributions.

description: We consider a question which curiously had not been properly considered so far: in the standard seesaw model what is the minimum value the mass of a right-handed (RH) neutrino must have for allowing successful leptogenesis via CP-violating decays? To answer this question requires to take into account a number of thermal effects. We show that, for low RH neutrino masses and thanks to these effects, leptogenesis turns out to proceed efficiently from the decay of the Standard Model (SM) scalar doublet components into a RH neutrino and a lepton. Such decays produce the asymmetry at low temperatures, slightly before sphaleron decoupling. If the RH neutrino has thermalized prior from producing the asymmetry, this mechanism turns out to lead to the bound $m_N>2$ GeV. If, instead, the RH neutrinos have not thermalized, leptogenesis from these decays is enhanced further and can be easily successful, even at lower scales. This Higgs-decay leptogenesis new mechanism works without requiring an interplay of flavor effects and/or cancellations of large Yukawa couplings in the neutrino mass matrix. Last but not least, such a scenario turns out to be testable, from direct production of the RH neutrino(s).

description: The Wiener's path integral plays a central role in the studies of Brownian motion. Here we derive exact path-integral representations for the more general \emph{fractional} Brownian motion (fBm) and for its time derivative process -- the fractional Gaussian noise (fGn). These paradigmatic non-Markovian stochastic processes, introduced by Kolmogorov, Mandelbrot and van Ness, found numerous applications across the disciplines, ranging from anomalous diffusion in cellular environments to mathematical finance. Still, their exact path-integral representations were previously unknown. Our formalism exploits the Gaussianity of the fBm and fGn, relies on theory of singular integral equations and overcomes some technical difficulties by representing the action functional for the fBm in terms of the fGn for the sub-diffusive fBm, and in terms of the derivative of the fGn for the super-diffusive fBm. We also extend the formalism to include external forcing. The exact and explicit path-integral representations open new inroads into the studies of the fBm and fGn.

Does mothers/caregivers'fasting status affect the dietary diversity of children 6-23 months? A before-after study in Debrebirhan, Ethiopia
Creators: name: Zebene, Addisalem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Background: Ethiopia has various religions, of which the Orthodox Tewahido Christian religion accounts for 44% of the population. According to the Ethiopian Orthodox Tewahido tradition close to 200 days are dedicated to religious fasting annually, at which time all followers who are above seven years old are expected to abstain from all types of food, including animal source foods, and water for up to some hours daily. It is possible that such practice by mothers or caregivers could affect children's food consumption. However, it is not clear if mothers/caregivers' fasting status influences the diversity of food that children are getting during these periods. Objective: The objective of this study was to estimate the effect of mothers/caregivers' fasting status on dietary diversity of children 6-23 months in Debrebirhan, Ethiopia, 2019 Methods: A community-based longitudnal study was conducted in Debrebirhan, North Shewa Zone, at randomly selected seven kebeles with a sample size of 218, from January 29 to February 25, 2019 in the pre-fasting period and from March 18 to April 10, 2019, during fasting period on same participants. Data was entered on Epi data version 4.4.2.1 and analyzed using STATA 15 software. Children's dietary diversity was measured using the WHO standardized questionnaire for infant and young child feeding. McNemar paired test was used for comparison of baseline and end line measurements. Statistical significance was determined at p<0.05. Result: A total of 218 and 216 mothers/caregivers with children 6-23 months participated in the study before and during fasting season with a response rate of 100.0% and 99.0% respectively. The median age of children was 15 months. It was found out that the proportion of children who ate four or more food groups in the pre-fasting period was 23.4% and it significantly decreased to 5.5% in the fasting period (p<0.0001). Conclusion: The study pointed out that mothers/caregivers' fasting status during the Ethiopian Orthodox Tewahido fasting periods could negatively affect the dietary diversity of children 6-23 months in the household apparently by decreasing their consumption of animal source food. Therefore, intervention strategies in promoting children's dietary diversity should be designed in a way that considers Ethiopian Orthodox Tewahido Christian mothers/caregivers' fasting practices.

description: In order to study the effect of the anti de Sitter/ conformal field theory correspondence (AdS/CFT) on the primordial inflationary era, we consider a universe filled with a tachyon field in a slow-roll regime. In this context, the background and perturbative parameters characterising the inflationary era are related to the standard one by correction terms. We show a clear agreement between the theoretical prediction and the observational data for the above mentioned model. The main results of our work are illustrated for an exponential potential. We show that, for a suitable conformal anomaly coefficient, AdS/CFT correspondence might leave its imprints on the spectrum of the gravitational waves amplitude with a tensor to scalar ratio, $r$, of the perturbations compatible with Planck data.

description: Developing functional metallic nanostructured surfaces has seen significant growth in various applications, including sensors, electronics, and biomedical devices. However, conventional fabrication techniques for these nanostructures face limitations such as complexity, high costs, and unstable coatings. Laser-assisted surface processing has emerged as a promising solution to address these challenges by enabling localized processing and modification without altering bulk properties. This dissertation focuses on the development of multifunctional devices using selective laser processing of metallized surfaces, categorized into three routes. The first part explores the utilization of laser-induced oxides (LIO) for simple processing and formation of functional metal oxide nanostructures as electrochemical sensing elements. Different laser processing conditions were systematically studied for cost-effective metals like copper and nickel, evaluating their potential as non-enzymatic glucose sensors. The second part investigates laser selective processing for removing metal coatings on temperature-sensitive substrates, providing a cost-effective and scalable alternative to conventional photolithography and etching processes. Various laser processing conditions were examined to achieve selective patterning of metalized fabric structures for wearable electronics production. The third part explores localized laser processing to create intermetallic nanotexturing mixtures without altering bulk properties. The study involved silver spray- coating onto titanium implants, followed by a post-laser processing. The aim was to achieve simultaneous texturing and intermixing of silver in titanium alloy structures, enhancing antibacterial properties and bone mineralization while preserving mechanical properties.Through the comprehensive examination of these three routes, this dissertation demonstrates the immense potential of commercial laser processing systems in the design, fabrication, and characterization of functional metallic nanostructured surfaces. It emphasizes the often-overlooked aspect of chemical alterations in laser-assisted surface processing, bridging the gap between physical and chemical modifications. The research opens new avenues for the development and optimization of multifunctional devices in electronics and biomedical applications.

description: We have carried out a high-precision astrometric analysis of two very-long-baseline-interferometry (VLBI) epochs of observation of the 13 extragalactic radio sources in the complete S5 polar cap sample. The VLBI epochs span a time baseline of 10 years and enable us to achieve precisions in the proper motions of the source cores up to a few micro-arcseconds per year. The observations were performed at 14.4 GHz and 43.1 GHz, and enable us to estimate the frequency core-shifts in a subset of sources, for which the spectral-index distributions can be computed. We study the source-position stability by analysing the changes in the relative positions of fiducial source points (the jet cores) over a decade. We find motions of 0.1-0.9 mas among close-by sources between the two epochs, which imply drifts in the jet cores of approximately a few tens of micro-as per year. These results have implications for the standard Active Galactic Nucleus (AGN) jet model (where the core locations are supposed to be stable in time). For one of our sources, 0615+820, the morphological and spectral properties in year 2010, as well as the relative astrometry between years 2000 and 2010, suggest the possibility of either a strong parsec-scale interaction of the AGN jet with the ISM, a gravitational lens with ~1 mas diameter, or a resolved massive binary black hole.

Charakterisierung zytotoxischer Pasteurella multocida-Toxin–Chimären

description: In der vorliegenden Arbeit wurde eine zytotoxische Pasteurella multocida-Toxin (PMT) -Variante etabliert und charakterisiert, die durch die gute Messbarkeit des Ereignisses „Zelltod“ von Vorteil für die Untersuchung des Aufnahmewegs ist. Dazu wurde ein Fusionsprotein aus enzymatisch inaktivem PMTC1165S und der ADP-Ribosylierungsdomäne von Diphtherietoxin (DTa), die alleine nicht in Zellen aufgenommen wird, konstruiert und untersucht. Die PMT-DTa-Chimäre konnte EF 2, das natürliche Zielprotein von DT in vitro und in HEK-293-Zellen ADP-ribosylieren. Dies führte, genau wie bei der Behandlung mit DT, zu einer Blockade der Proteinbiosynthese und damit zum Zelltod. Die in dieser Arbeit gewonnenen Daten sprechen dafür, dass PMT-DTa an denselben Oberflächenrezeptor wie PMT bindet. Es wurde gezeigt, dass die Translokation des Toxins in das Zytosol abhängig von der endosomalen Azidifizierung ist. Fluoreszenz-markiertes PMT-DTa ließ sich in frühen und späten Endosomen, nicht jedoch im Golgi-Apparat identifizieren. Die gleichen Befunde zeigten auch Versuche mit PMTwt, sodass davon auszugehen ist, dass die Aufnahme des Fusionsproteins PMT-DTa alleine von seiner PMT-Komponente abhängig ist. Es konnte gezeigt werden, dass die N-terminale Region von Aminosäure 1-505 des PMT-Fragments ausreichend ist, um die Aufnahme und Translokation des Toxins in das Zytosol zu induzieren. Eine Deletion der vorhergesagten hydrophoben α Helices verhindert die Translokation, wodurch das bestehende Domänenmodell von PMT unterstützt wird. Weiterhin wurde die Abhängigkeit der Toxin-Aufnahme vom Phosphatidylinositol-Stoffwechsel nachgewiesen. Hier ergibt sich ein Ansatzpunkt für zukünftige Untersuchungen. Zusammenfassend konnte im Rahmen dieser Dissertation ein zytotoxisches PMT-DTa-Fusionstoxin etabliert werden, das den PMT-spezifischen Aufnahmeweg in die Zelle nimmt. PMT-DTa könnte in Zukunft ein wertvolles molekulares Werkzeug zur Untersuchung der Endozytoseroute von PMT und zur Identifizierung des Oberflächenrezeptors werden.

description: We consider the problem of learning Stochastic Differential Equations of the form $dX_t = f(X_t)dt+σ(X_t)dW_t $ from one sample trajectory. This problem is more challenging than learning deterministic dynamical systems because one sample trajectory only provides indirect information on the unknown functions $f$, $σ$, and stochastic process $dW_t$ representing the drift, the diffusion, and the stochastic forcing terms, respectively. We propose a method that combines Computational Graph Completion and data adapted kernels learned via a new variant of cross validation. Our approach can be decomposed as follows: (1) Represent the time-increment map $X_t \rightarrow X_{t+dt}$ as a Computational Graph in which $f$, $σ$ and $dW_t$ appear as unknown functions and random variables. (2) Complete the graph (approximate unknown functions and random variables) via Maximum a Posteriori Estimation (given the data) with Gaussian Process (GP) priors on the unknown functions. (3) Learn the covariance functions (kernels) of the GP priors from data with randomized cross-validation. Numerical experiments illustrate the efficacy, robustness, and scope of our method.

Using the cosmological recombination radiation to probe early dark energy and fundamental constant variations

description: The cosmological recombination radiation (CRR) is one of the guaranteed spectral distortion signals from the early Universe. The CRR photons from hydrogen and helium pre-date the last scattering process and as such allow probing physical phenomena in the pre-recombination era. Here we compute the modifications to the CRR caused by early dark energy models and varying fundamental constants. These new physics examples have seen increased recent activity in connection with the Hubble tension, motivating the exploratory study presented here. The associated CRR responses are spectrally-rich but the level of the signals is small. We forecast the possible sensitivity of future spectrometers to these effects. Our estimates demonstrate that the CRR directly depends to changes in the expansion history and recombination physics during the pre-recombination era. However, futuristic sensitivities are required for spectrometer-only constraints that are competitive with other cosmological probes. Nevertheless, measurements of the CRR can directly reach into phases that otherwise remain inaccessible, highlighting the potential these types of observations could have as a probe of the early Universe. A combination with ${\it Planck}$ data further shows that a synergistic approach is very promising.
