description: Genomes contain rare guanine-rich sequences capable of assembling into four-stranded helical structures, termed G-quadruplexes, with potential roles in gene regulation and chromosome stability. Their mechanical unfolding has only been reported to date by all-atom simulations, which cannot dissect the major physical interactions responsible for their cohesion. Here, we propose a mesoscopic model to describe both the mechanical and thermal stability of DNA G-quadruplexes, where each nucleotide of the structure, as well as each central cation located at the inner channel, is mapped onto a single bead. In this framework we are able to simulate loading rates similar to the experimental ones, which are not reachable in simulations with atomistic resolution. In this regard, we present single-molecule force-induced unfolding experiments by a high-resolution optical tweezers on a DNA telomeric sequence capable of forming a G-quadruplex conformation. Fitting the parameters of the model to the experiments we find a correct prediction of the rupture-force kinetics and a good agreement with previous near equilibrium measurements. Since G-quadruplex unfolding dynamics is halfway in complexity between secondary nucleic acids and tertiary protein structures, our model entails a nanoscale paradigm for non-equilibrium processes in the cell.
title: Optimization of a Porous SiCN(O) Ceramic Matrix for the Application as an Anode in Sodium-ion and Sodium-Metal Batteries
Creators: name: Melzi d'Eril, Marco
Publisher: name: UNSPECIFIED
Year: 2024

description: Batteries play a pivotal role in powering various everyday-use devices, ranging from portable electronics to electric vehicles and renewable energy storage. As the demand for efficient and sustainable energy solutions grows, the exploration of alternative battery materials becomes fundamental. The substitution of lithium with sodium represents an appealing transition due to the abundance of sodium resources, cost-effectiveness, and the potential to address concerns associated with lithium scarcity. This work centers on an in-depth investigation of a polymer-derived SiCN(O) porous matrix employed as an anode for sodium-ion and metallic batteries. The SiCN(O) porous matrix is comprehensively characterized to elucidate its structural and chemical properties. A crucial investigation in this work concerns the optimization of the porosity of the matrix to achieve a reversible Na-plating in the pores of the ceramic. Additionally, an in-depth exploration of the overall storage mechanism within this matrix employs advanced techniques, including operando Raman spectroscopy and dynamic electrochemical impedance spectroscopy. A further study involves the investigation of storage properties of SiOC ceramic in dependence of the material microstructure obtained with slow and ultra-fast heating. Using an ultra-fast furnace enhances both the efficiency and the speed of the pyrolysis process. This thesis aims to design, optimize and characterize an innovative sodium storage system with a porous ceramic as a plating matrix. In parallel novel promising anode materials for Na-Ion batteries have been developed.

Revisiting Vector-like Quark Model with Enhanced Top Yukawa Coupling

description: We revisit a scenario with an enhanced top yukawa coupling in vector-like quark (VLQ) models, where the top yukawa coupling is larger than the standard model value and the lightest VLQ has a negative yukawa coupling. We find that the parameter space satisfying the LHC bounds of the Higgs signal strengths consistently with the precision measurements is rather wide. Because the Lagrangian parameters of the yukawa couplings are large, such scenario can be realized in some strongly interacting theories. It also turns out that there is a noticeable relation between the contributions of the triangle and box diagrams in the $gg \to hh$ process by using the lowest order of the $1/M$ expansion where $M$ is the heavy mass running in the loops.

description: We present the three-loop calculation of the Bremsstrahlung function associated to the 1/2-BPS cusp in ABJM theory, including color subleading corrections. Using the BPS condition we reduce the computation to that of a cusp with vanishing angle. We work within the framework of heavy quark effective theory (HQET) that further simplifies the analytic evaluation of the relevant cusp anomalous dimension in the near-BPS limit. The result passes nontrivial tests, such as exponentiation, and is in agreement with the conjecture made in [1] for the exact expression of the Bremsstrahlung function, based on the relation with fermionic latitude Wilson loops.

description: We present a model of contagion that unifies and generalizes existing models of the spread of social influences and micro-organismal infections. Our model incorporates individual memory of exposure to a contagious entity (e.g., a rumor or disease), variable magnitudes of exposure (dose sizes), and heterogeneity in the susceptibility of individuals. Through analysis and simulation, we examine in detail the case where individuals may recover from an infection and then immediately become susceptible again (analogous to the so-called SIS model). We identify three basic classes of contagion models which we call \textit{epidemic threshold}, \textit{vanishing critical mass}, and \textit{critical mass} classes, where each class of models corresponds to different strategies for prevention or facilitation. We find that the conditions for a particular contagion model to belong to one of the these three classes depend only on memory length and the probabilities of being infected by one and two exposures respectively. These parameters are in principle measurable for real contagious influences or entities, thus yielding empirical implications for our model. We also study the case where individuals attain permanent immunity once recovered, finding that epidemics inevitably die out but may be surprisingly persistent when individuals possess memory.

description: A memristor is one of four fundamental two-terminal solid elements in electronics. In addition with the resistor, the capacitor and the inductor, this passive element relates the electric charges to current in solid state elements. Here we report the existence of a thermal analog for this element made with metal-insulator transition materials. We demonstrate that these memristive systems can be used to create thermal neurons opening so the way to neuromophic networks for smart thermal management and information treatment.

description: The gravity gradient is one of the most serious systematic effects in atomic tests of the equivalence principle (EP). While differential acceleration measurements performed with different atomic species under free fall test the validity of EP, minute displacements between the test masses in a gravity gradient produces a false EP-violating signal that limits the precision of the test. We show that gravity inversion and modulation using a gimbal mount can suppress the systematics due to gravity gradients caused by both moving and stationary parts of the instrument as well as the environment, strongly reducing the need to overlap two species.

description: We investigate single photon scattering properties in one-dimensional waveguide coupled to quantum emitter's chain with dipole-dipole interaction (DDI). The photon transport is extremely sensitive to the location of the evanescently coupled emitters. The analytical expressions of reflection and transmission amplitudes for the chain containing two emitters with DDI are deduced by using real-space Hamiltonian. Two cases, where the two emitters symmetrically and asymmetrically couple to the waveguide, are discussed in detail. It shows that the reflection and transmission typical spectra split into two peaks due to the DDI. The Fano minimum in the spectra can also be used to estimate the strength of the DDI. Furthermore, the DDI makes spectra strongly asymmetric and create a transmission window in the region where there was zero transmission. The scattering spectra for the chain consisting of multi-emitters are also given. Our key finding is that DDI can broaden the frequency band width for high reflection when the chain consists of many emitters.

description: We study the correlations of D mesons produced in $p$+$p$ and $p$+Pb collisions. These are found to be sensitive to the effects of the cold nuclear medium and the transverse momentum ($p_T$) regions we are looking into. In order to put this on a quantitative footing, as a first step we analyse the azimuthal correlations of D meson-charged hadron(Dh), and then predict the same for D meson -anti D meson ($D\overline{D}$) pairs in $p$+$p$ and $p$+Pb collisions with strong coupling at leading order $\cal{O}$($α_{s}^{2}$) and next to leading order $\cal{O}$($α_{s}^{3}$) which includes space-time evolution (in both systems), as well cold nuclear matter effects (in $p$+Pb). This also sets the stage and baseline for the identification and study of medium modification of azimuthal correlations in relativistic collision of heavy nuclei at the Large Hadron Collider.

description: We study a superconducting transmission line (TL) formed by distributed LC oscillators and excited by external magnetic fluxes which are aroused from random magnetization (A) placed in substrate or (B) distributed at interfaces of a two-wire TL. Low-frequency dynamics of a random magnetic field is described based on the diffusion Langevin equation with a short-range source caused by (a) random amplitude or (b) gradient of magnetization. For a TL modeled as a two-port network with open and shorted ends, the effective magnetic flux at the open end has non-local dependency on noise distribution along the TL. The flux-flux correlation function is evaluated and analyzed for the regimes (Aa), (Ab). (Ba), and (Bb). Essential frequency dispersion takes place around the inverse diffusion time of random flux along the TL. Typically, noise effect increases with size faster than the area of TL. The flux-flux correlator can be verified both via the population relaxation rate of the qubit, which is formed by the Josephson junction shunted by the TL with flux noises, and via random voltage at the open end of the TL.

description: We demonstrate theoretically that the interaction of electrons in gapped Dirac materials (gapped graphene and transition-metal dichalchogenide monolayers) with a strong off-resonant electromagnetic field (dressing field) substantially renormalizes the band gaps and the spin-orbit splitting. Moreover, the renormalized electronic parameters drastically depend on the field polarization. Namely, a linearly polarized dressing field always decreases the band gap (and, particularly, can turn the gap into zero), whereas a circularly polarized field breaks the equivalence of valleys in different points of the Brillouin zone and can both increase and decrease corresponding band gaps. As a consequence, the dressing field can serve as an effective tool to control spin and valley properties of the materials and be potentially exploited in optoelectronic applications.

description: Abstract
Background: Health and Demographic Surveillance System sites are the primary source of community-based death and cause of death data, providing essential policy inputs. Currently, many African countries, including Ethiopia, have undergone different stages of epidemiological transition.
Objective: To assess the epidemiologic transition in the Butajira community in south-central Ethiopia.
Methods: All deaths registered in the Butajira Health and Demographic Surveillance System databases were included. The trend in the overall mortality rate and the change in the proportion of major causes of death were evaluated, and significant trends were checked using the Mann-Kendall statistical test with significance set at P< 0.05.
Results: The overall mortality rate per 1000 population declined from 9.8 in 1987 to 2.8 in 2016. The decline was significant (tau, the measure of the strength and direction of association,= -0.76, p-value <0.05). During this study period, 2610 deaths were registered in the Health and Demographic Surveillance System database, of which 1,625 were adults. The proportion of yearly deaths attributed to communicable diseases, maternal and perinatal conditions, and nutritional deficiencies showed a significant decline (tau = -0.727, p < 0.05), while there was a significant increase in non-communicable diseases (tau = 0.469, p < 0.05), and a rise in external causes (tau = 0.0953, p > 0.05). Furthermore, there were notable changes in the death proportion in the top five leading causes of death, showing a transition in the epidemiology of major causes of death, especially in the age group 15+.
Conclusion: The decline in mortality and burden shift implies the existence of an epidemiological transition. This transition necessitates policymakers to design a responsive health system that cater to the population undergoing this epidemiological transition. [Ethiop. J.

description: We elucidate the importance of the consistent treatment of gravity-model specific non-linearities when estimating the growth of cosmological structures from redshift space distortions (RSD). Within the context of standard perturbation theory (SPT), we compare the predictions of two theoretical templates with redshift space data from COLA (COmoving Lagrangian Acceleration) simulations in the normal branch of DGP gravity (nDGP) and General Relativity (GR). Using COLA for these comparisons is validated using a suite of full N-body simulations for the same theories. The two theoretical templates correspond to the standard general relativistic perturbation equations and those same equations modelled within nDGP. Gravitational clustering non-linear effects are accounted for by modelling the power spectrum up to one loop order and redshift space clustering anisotropy is modelled using the Taruya, Nishimichi and Saito (TNS) RSD model. Using this approach, we attempt to recover the simulation's fiducial logarithmic growth parameter $f$. By assigning the simulation data with errors representing an idealised survey with a volume of $10\mbox{Gpc}^3/h^3$, we find the GR template is unable to recover fiducial $f$ to within 1$σ$ at $z=1$ when we match the data up to $k_{\rm max}=0.195h$/Mpc. On the other hand, the DGP template recovers the fiducial value within $1σ$. Further, we conduct the same analysis for sets of mock data generated for generalised models of modified gravity using SPT, where again we analyse the GR template's ability to recover the fiducial value. We find that for models with enhanced gravitational non-linearity, the theoretical bias of the GR template becomes significant for stage IV surveys. Thus, we show that for the future large data volume galaxy surveys, the self-consistent modelling of non-GR gravity scenarios will be crucial in constraining theory parameters.

description: Abstract
Background: Anti-retroviral therapy in most parts of the world, including Ethiopia, has allowed HIV patients to live longer but with a corresponding rise in risk of developing non-communicable diseases (NCDs). Hence, this study aimed to describe the magnitude of behavioural, physical, and biochemical risk factors for NCDs among people living with human immunodeficiency virus (PLHIV) in Ethiopia.
Methods: A facility-based cross-sectional study was conducted in chronic HIV care clinics at five health facilities in Addis Ababa, Ethiopia. A total of 413 HIV patients were included in the study. A World Health Organization STEP survey tool was used to assess common risk factors for NCDs. Biochemical risk factors were assessed on half (207) of the study participants. Descriptive statistics was used to determine the magnitude of the behavioral, physical, and biochemical risk factors for NCDs.
Results: About 10.2% (42) of the PLHIV had a history of ever smoking tobacco, and 52.8% (218) of participants were lifetime alcohol consumers. About 86.4% (357) did not consume vegetables on a regular basis. Overall, 13.1 % (54) had elevated total systolic blood pressure, 23.7% (98) had elevated diastolic blood pressure, and 11.8% of females and 3.8% of males had increased waist circumference. Of the total participants, 13.1% (53) were underweight, and 2.5% (10) were in the obese category. Among the samples collected, 34.7% (72) had elevated fasting blood sugar, and 21.3% (44) had elevated cholesterol levels.
Conclusions: The behavioral, physical, and biochemical risk factors of NCDs are common among PLWHIV. Incorporation of risk factors assessment to NCDs and timely advice by professionals will have far-reaching positive benefits on the well-being of PLWHIV. [Ethiop. J. Health Dev. 2023; 37(3) 000-000]

description: Recently, the Cachazo-He-Yuan (CHY) approach for calculating scattering amplitudes has been extended beyond tree level. In this paper, we introduce a way of constructing CHY integrands for $Φ^3$ theory up to two loops from holomorphic forms on Riemann surfaces. We give simple rules for translating Feynman diagrams into the corresponding CHY integrands. As a complementary result, we extend the $Λ$-algorithm, originally introduced in arXiv:1604.05373, to two loops. Using this approach, we are able to analytically verify our prescription for the CHY integrands up to seven external particles at two loops. In addition, it gives a natural way of extending to higher-loop orders.

description: Quasi-two-dimensional (quasi-2D) foams consist of monolayers of bubbles squeezed between two narrowly spaced plates. These simplified foams have served successfully in the past to shed light on numerous issues in foam physics. Here we consider the electrical conductivity of such model foams. We compare experiments to a model which we propose, and which successfully relates the structural and the conductive properties of the foam over the full range of the investigated liquid content. We show in particular that in the case of quasi-2D foams the liquid in the nodes needs to be taken into account even at low liquid content. We think that these results may provide different approaches for the characterization of foam properties and for the in situ characterization of the liquid content of foams in confining geometries, such as microfluidics

description: Recent spectropolarimetric observations of otherwise ordinary G, K, and M giants revealed localized magnetic strips in the HRD coincident with the regions where the first dredge-up and core He-burning occur. We seek to understand the origin of magnetic fields in such late-type giant stars. In analogy with late-type dwarf stars, we focus primarily on parameters known to influence the generation of magnetic fields in the outer convective envelope. We compute the classical dynamo parameters along the evolutionary tracks of low- and intermediate-mass stars at various metallicities using stellar models that have been extensively tested by spectroscopic and asteroseismic observations. These include convective turnover timescales and convective Rossby numbers, computed from the PMS to the tip of the RGB or the early AGB. To investigate the effects of the very extended outer convective envelope, we compute these parameters both for the entire convective envelope and locally, that is, at different depths within the envelope. We also compute the turnover timescales and corresponding Rossby numbers for the convective cores of intermediate-mass stars on the main sequence. Our models show that the Rossby number of the convective envelope becomes lower than unity in the well-delimited locations of the Hertzsprung-Russell diagram where magnetic fields have indeed been detected. We show that alpha-omega dynamo processes might not be continuously operating, but that they are favored in the stellar convective envelope at two specific moments along the evolution tracks, that is, during the first dredge-up at the base of the RGB and during central helium burning in the helium-burning phase and early-AGB. This general behavior can explain the so-called magnetic strips recently discovered by dedicated spectropolarimetric surveys of evolved stars.

description: The ARIANNA hexagonal radio array (HRA) is an experiment in its pilot phase designed to detect cosmogenic neutrinos of energies above 10^16 eV. The most neutrino-like background stems from the radio emission of air showers. This article reports on dedicated efforts of simulating and detecting the signals of cosmic rays. A description of the fully radio self-triggered data-set, the properties of the detected air shower signals in the frequency range of \unit[100-500]{MHz} and the consequences for neutrino detection are given. 38 air shower signals are identified by their distinct waveform characteristics, are in good agreement with simulations and their signals provide evidence that neutrino-induced radio signals will be distinguishable with high efficiency in ARIANNA. The cosmic ray flux at a mean energy of $6.5^{+1.2}_{-1.0}\times10^{17}$ eV is measured to be $1.1^{+1.0}_{-0.7}\times10^{-16}$ eV$^{-1}$km$^{-2}$sr$^{-1}$yr$^{-1}$ and one five-fold coincident event is used to illustrate the capabilities of the ARIANNA detector to reconstruct arrival direction and energy of air showers.

description: Tiderne, hvor surveys blev besvaret enten ved hjælp af en interviewer eller på papir hjemme ved spisebordet, er under forandring. Fremvæksten af nye webbaserede indsamlingsmetoder og besvarelses-devices betyder, at respondenter i dag kan udfylde surveyen på mange forskellige måder og i mange forskellige kontekster. Hvor det muligvis er positivt for svarprocenten, rejser det imidlertid spørgsmålet om, hvorvidt det er befordrende for respondenternes engagement i besvarelsen og i sidste ende påvirker kvaliteten af data negativt. På baggrund af en repræsentativ befolkningssurvey finder denne artikel dog, at der ikke er forskel på web survey-besvarelser på henholdsvis PC, tablet og smartphone. Når der tages højde for, at nogle grupper foretrækker bestemte devices frem for andre, såkaldte selektionseffekter, så er der ingen forskel på, hvor meget respondenterne engagerer sig, hverken når de selv skal vurdere det, eller når vi måler det som tiden brugt på besvarelsen. Derfor er det anbefalingen til afsendere af web surveys, at de ikke skal afstå fra at udbyde web surveys på forskellige devices. Tværtimod tyder det på, at fordelene ved at tillade mobile besvarelser overstiger ulemperne, hvis blot der tages højde for, at web survey-layoutet er optimeret til det.

description: In a project aimed at measuring the optical Extragalactic Background Light (EBL) we are using the shadow of a dark cloud.We have performed, with the ESO VLT/FORS, spectrophotometry of the surface brightness towards the high-galactic-latitude dark cloud Lynds 1642. A spectrum representing the difference between the opaque core of the cloud and several unobscured positions around the cloud was presented in Paper I (Mattila et al. 2017a). The topic of the present paper is the separation of the scattered starlight from the dark cloud itself which is the only remaining foreground component in this difference. While the scattered starlight spectrum has the characteristic Fraunhofer lines and the discontinuity at 400 nm, typical of integrated light of galaxies, the EBL spectrum is a smooth one without these features. As template for the scattered starlight we make use of the spectra at two semi-transparent positions. The resulting EBL intensity at 400 nm is $I_{\rm EBL} = 2.9\pm1.1$ $10^{-9}$ erg cm$^{-2}$s$^{-1}$sr$^{-1}$Å$^{-1}$, or $11.6\pm4.4$ nW m$^{-2}$sr$^{-1}$, which represents a 2.6$σ$ detection; the scaling uncertainty is +20%/-16%. At 520 nm we have set a 2$σ$ upper limit of $I_{\rm EBL} \le$4.5 $10^{-9}$ erg cm$^{-2}$s$^{-1}$sr$^{-1}$Å$^{-1}$ or $\le$23.4 nW m$^{-2}$sr$^{-1}$ +20%/-16%. Our EBL value at 400 nm is $\ge 2$ times as high as the integrated light of galaxies. No known diffuse light sources, such as light from Milky Way halo, intra-cluster or intra-group stars appear capable of explaining the observed EBL excess over the integrated light of galaxies.

description: Time-Series Cross-Section (TSCS) analyser anvendes ofte inden for komparativ politik og politisk økonomi. Betegnelsen TSCS henviser til, at, at man har en tids-dimension med perioder og en tværsnits-dimension med enheder De samme enheder observeres således over tid. Den metodiske litteratur om TSCS analyser antager oftest, at læseren kender til en række grundelementer i mødet med TSCS. I stedet fokuserer litteraturen på bestemte nye modeller og sammenligning af estimations­metoder. Vi giver her en samlet introduktion til grundelementerne, man som minimum bør være opmærksom, når man udfører TSCS analyser. De seks elementer, vi fokuserer på, er: (1) det teoretiserede forhold og variabeltyper, (2) ikke-stationære variable og håndtering heraf, (3) modelvalg og homogene/heterogene effekter, (4) lagstrukturer, (5) brugen af fixed effects og (6) kausalitet og tolkning af TSCS analyser. Alle elementer er bundet sammen ved et fælles mål om at skabe sammenhæng mellem teori, data og metode. Artiklen afsluttes med en TSCS ’kogebog’, der opsummerer de 6 punkter og giver en introducerende guide til TSCS analyser.

Realistisk evaluering: Et supplement eller et alternativ til effektevaluering?
Creators: name: Ravn, Rasmus
Publisher: name: Metode & Forskningsdesign
Year: 2020

description: Til at undersøge effekter anses det randomiserede kontrollerede forsøg (RCT[1]) som guldstandarden for evidens. De senere år har eksperimentelle og kvasi-eksperimentelle tilgange til effektevaluering imidlertid fået konkurrence af teoridrevne evalueringstilgange. Disse nyere tilgange undersøger, hvad der virker, for hvem, under hvilke omstændigheder det virker, og hvorfor en indsats virker. Der er især tale om den ”realistiske evaluering”, der på dansk ofte benævnes ”virkningsevaluering”. Artiklens formål er at illustrere, hvordan man som forsker eller evaluator vil kunne designe en evaluering, der kombinerer realistisk evaluering med mere klassisk effektevaluering. Der skelnes i artiklen mellem integreret og sekventiel modelanvendelse, og det konkluderes og illustreres, at kombinationsformen har afgørende betydning for, hvilke indsigter man kan nå frem som evaluator. Blandt realistiske evaluatorer er der imidlertid dyb uenighed om, hvorvidt modellerne kan og bør kombineres. Ophavsmændene til den realistiske evaluering er kritiske over for modelkombination, fordi de anser den realistiske kausalitetsforståelse som uforenelig med evaluering, hvor den kontrafaktiske situation etableres. Hovedparten af artiklen bruges derfor på at blotlægge og diskutere evalueringsmodellernes syn på kausalitet og metodeanvendelse ud fra et realistisk perspektiv. Det sker med henblik på at synliggøre de vigtigste argumenter for og imod at kombinere modellerne.

description: Abstract
Background: Conventional wisdom holds that the microbiological detection of Mycobacterium tuberculosis complex in clinical specimens via culture and phenotypic drug susceptibility testing allows people to be correctly diagnosed and ensures that an effective treatment regimen is selected.
Aim: The objective of this study was to provide a description of the drug resistance profiles of first-line and second-line anti-tuberculous drugs among individuals newly diagnosed with pulmonary tuberculosis in the Addis Ababa metropolitan area, located in Ethiopia.
Methods: A cross-sectional study was conducted between October 2019 and June 2021 on clinically suspected and bacteriologically confirmed pulmonary tuberculosis cases. The GeneXpert MTB/RIF assay was used to detect Mycobacterium tuberculosis complex and resistant to rifampicin. Mycobacterial culture and drug susceptibility testing were performed against 15 anti-tuberculosis drugs using the BD BACTEC™ MGIT™ 960 automated liquid culture system.
Results: A total of 156 Mycobacterium tuberculosis complex isolates were successfully recovered. Males account for 53.8 % [84/156]. Overall, 14.1% [22/156] of isolates were resistant to at least one drug, 85.9 % [134/156] of isolates were pan-susceptible, 7.1% [11/156] of isolates were mono-resistant strains, 5.8% [9/156] of isolates were multidrug-resistant strains, and 3.8% [6/156] of isolates were resistant to all first-line drugs. Interestingly, all isolates were susceptible to all recently recommended second-line drugs tested. Nevertheless, compared to the reference method, the rate of rifampicin resistance detected using GeneXpert MTB/RIF assay had a sensitivity, specificity, and accuracy of 100% [95% CI: 66.4 – 100], 94.6 [95% CI: 89.6 – 97.6], and 94.9 [95% CI: 90.2 – 97.8] respectively, with moderate level of agreement at Cohen kappa value of 0.667.
Conclusion: The rate of MDR-TB in new pulmonary TB cases remained high, at fivefold the national and nearly twofold the global estimated rate in this study. The rate of monoresistance was also high and alarming. The rate of resistance against second-line anti-TB drugs was absent and quite encouraging. The use of GeneXpert MTB/RIF assay alone for the detection of M. tuberculosis introduces 15.7% [34/216] false positivity and 47.1% [8/17] false rifampicin resistance. Treatment initiation with second-line medications without initial drug susceptibility test results may lead to erroneous decisions. [Ethiop. J. Health Dev. 2023; 37(2) 000-000]
