Creators: name: Meshesha, Asnake
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This study was undertaken to investigate the effect of advertisement on consumers buying behavior in case of Nifas Silk Paints Factory. The literature provided discusses the concept of advertisement and consumers buying behavior. The researcher used Descriptive and explanatory research approach which describes and explains quantitatively the effect of advertisement on consumers buying behavior. Information was gathered from a sample of 384 consumers. Advertisement was identified as the independent variable and consumers buying behavior as the dependent variable. Impressive, understandable, attention grabbing, memorable, creative and honest advertisements were considered as sub-variables of advertisement. Data obtained from the respondents was then analyzed. Two-tailed correlation analysis showed that there is a strong and positive relationship between impressive, understandable, attention grabbing, memorable, creative & honest advertisement and consumers buying behavior. The correlation analysis also indicates a moderate and positive relationship between impressive, memorable & creative advertisements and consumers buying behavior. Multiple regressions were also applied. The results were according to the expectation after theory examination, but attention grabbing advertisement has insignificant contribution on consumers buying behavior. On the other hand simple to understand advertisement contributes the largest effect towards influencing consumers buying behavior. Based on the result of this research it is recommended that effective advertisement campaign which includes the aforementioned predictors should be practiced to attract more consumers and to gain competitive advantage against rivals. This research therefore adds a new dimension to the body of literature that will help researchers' efforts to understand the effect of advertisement on consumers buying behavior

description: We present an estimate of the occurrence rate of hot Jupiters ($7\ R_{\oplus}\leq R_{p}\leq 2\ R_{J}$, $0.8 \leq P_{b}\leq 10$ days) around early-type M dwarfs based on stars observed by TESS during its Primary Mission. We adopt stellar parameters from the TESS Input Catalog, and construct a sample of 60,819 M dwarfs with $10.5 \leq T_{\rm mag}\leq 13.5$, effective temperature $2900 \leq T_{\rm eff}\leq 4000\ K$ and stellar mass $0.45\leq M_{\ast}\leq 0.65\ M_{\odot}$. We conduct a uninformed transit search using a detection pipeline based on the box least square search and characterize the searching completeness through an injection and recovery experiment. We combine a series of vetting steps including light centroid measurement, odd/even and secondary eclipse analysis, rotation and transit period synchronization tests as well as inspecting the ground-based photometric, spectroscopic and imaging observations. Finally, we find a total of nine planet candidates, all of which are known TESS objects of interest. We obtain an occurrence rate of $0.27\pm0.09\%$ for hot Jupiters around early-type M dwarfs that satisfy our selection criteria. Compared with previous studies, the occurrence rate of hot Jupiters around early-type M dwarfs is smaller than all measurements for FGK stars, although they are consistent within 1--2$σ$. Combining results from transit, radial velocity and microlensing surveys, we find that hot Jupiters around early-type M dwarfs possibly show a steeper decrease in occurrence rate per logarithmic semi-major axis bin (${{\rm d}N}/{\rm d}\log_{10} a$) when compared with FGK stars.

description: We study the compositeness of near-threshold states to investigate the internal structure of exotic hadron candidates. Within the framework of effective field theory, Weinberg's weak-binding relation is extended to more general cases by easing several preconditions. First, by evaluating the contribution from the decay channel, we obtain the generalized relation for unstable quasibound states. Next, we generalize the relation to include the nearby CDD (Castillejo-Dalitz-Dyson) pole contribution with the help of the Pade approximant. The validity of the estimation with the generalized weak-binding relations is examined by numerical calculations. The method to systematically evaluate the error in the weak-binding relation is presented. Finally, by applying the extended relation to Lambda(1405), f0(980) and a0(980), we discuss their internal structure, in comparison with other approaches.

description: Optically active spin defects in van der Waals materials are promising platforms for modern quantum technologies. Here we investigate the coherent dynamics of strongly interacting ensembles of negatively charged boron-vacancy ($\mathrm{V}_{\mathrm{B}}^-$) centers in hexagonal boron nitride (hBN) with varying defect density. By employing advanced dynamical decoupling sequences to selectively isolate different dephasing sources, we observe more than 5-fold improvement in the measured coherence times across all hBN samples. Crucially, we identify that the many-body interaction within the $\mathrm{V}_{\mathrm{B}}^-$ ensemble plays a substantial role in the coherent dynamics, which is then used to directly estimate the concentration of $\mathrm{V}_{\mathrm{B}}^-$. We find that at high ion implantation dosage, only a small portion of the created boron vacancy defects are in the desired negatively charged state. Finally, we investigate the spin response of $\mathrm{V}_{\mathrm{B}}^-$ to the local charged defects induced electric field signals, and estimate its ground state transverse electric field susceptibility. Our results provide new insights on the spin and charge properties of $\mathrm{V}_{\mathrm{B}}^-$, which are important for future use of defects in hBN as quantum sensors and simulators.

description: Bio-active compounds present in West Indian Wood Nettle Laportea aestuans (L.) Chew (Urticaceae), used in ethno medicine as antioxidant and antimicrobial were studied. The aim of this research work was to isolate and characterize the bio-active compounds in the n-hexane fraction of L. aestuans, determine the toxicity and subject it to in-vitro antimicrobial and free radical scavenging activities. The chemical constituents were isolated by gradient elution column chromatographic technique and Ultra Violet/visible (UV), Infrared (IR) and Nuclear Magnetic Resonance (NMR) spectroscopies were used for structural elucidation. The free radical scavenging activity of the isolate was assessed using three methods; scavenging effect on 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), hydroxyl radical generated from hydrogen peroxide and ferric thiocynate method. Antimicrobial screening was done by agar well diffusion method while toxicity was determined by Brine shrimp lethality test. Structures were proposed for the white crystalline solids isolated; (4E)-3,6-dimethylhep-4-en-3-ol (AB) and 1,2,3,4,4a,4b,5,6,6a,7,8,9,10,10a,10b,11-hexadecahydro-1,1,6a,10b-tetramethyl-7-((E)-4,7-dimethyloct-5-enyl) chrysen-2-ol (AC). Percentage yield of AC was 91.2 and was non-toxic with LC50 (μg/ml) value of 1581233000.0. AC significantly scavenged free radical at 0.0625 mg/ml in the DPPH (64.73 %) and hydrogen peroxide (99.22 %) tests. It also showed 65.23 % inhibition at 1.0 mg/ml in the ferric thiocyanate test. AC also inhibited microbial growth significantly when compared with gentamicin and tioconazole which are antibacterial and antifungal standards respectively. The presence of Chrysen-2-ol derivative in L. aestuans which was non-toxic and possessed significant antimicrobial and antioxidant activities supports its ethno medicinal application.

description: Gravitational lensing of gravitational waves provides a potential new probe of dark matter structures. In this work, we consider the microlensing effect on gravitational wave signals from black hole binaries induced by low-mass dark matter halos that do not retain enough baryonic matter to hold stars. We clarify systematically when this microlensing effect is relevant and study in detail its detectability by future gravitational wave observatories. We consider lensing by cold dark matter halos and by solitonic cores that reside in fuzzy dark matter halos. Our results show that although the effect can be detectable at relatively large impact parameters, the probability of detecting such lensed events is low. In particular, we find that the expected number of events lensed by cold dark matter halos is $O(0.01)$ per year for BBO and the expected number of events lensed by solitonic cores inside fuzzy dark matter halos is $O(0.01)$ per year for ET. In the case that a significant fraction of dark matter consists of $=O(100 M_\odot)$ objects that are relatively compact, $R < O(0.1\,{\rm pc})$, we show that the expected number of lensed events per year ET can be very large, $0(1000)$.

This generalizes a result of Bekka, and answers affirmatively a question of Bédos, Conti and Tuset. As a corollary, we extend to locally compact quantum groups a result of the first-named author, which characterizes amenability of a locally compact group $G$ by nuclearity of the reduced group $C^{*}$-algebra $C_{r}^{*}(G)$ and an additional condition.

description: The detection of earthquakes is a fundamental prerequisite for seismology and contributes to various research areas, such as forecasting earthquakes and understanding the crust/mantle structure. Recent advances in machine learning technologies have enabled the automatic detection of earthquakes from waveform data. In particular, various state-of-the-art deep-learning methods have been applied to this endeavour. In this study, we proposed and tested a novel phase detection method employing deep learning, which is based on a standard convolutional neural network in a new framework. The novelty of the proposed method is its separate explicit learning strategy for global and local representations of waveforms, which enhances its robustness and flexibility. Prior to modelling the proposed method, we identified local representations of the waveform by the multiple clustering of waveforms, in which the data points were optimally partitioned. Based on this result, we considered a global representation and two local representations of the waveform. Subsequently, different phase detection models were trained for each global and local representation. For a new waveform, the overall phase probability was evaluated as a product of the phase probabilities of each model. This additional information on local representations makes the proposed method robust to noise, which is demonstrated by its application to the test data. Furthermore, an application to seismic swarm data demonstrated the robust performance of the proposed method compared with those of other deep learning methods. Finally, in an application to low-frequency earthquakes, we demonstrated the flexibility of the proposed method, which is readily adaptable for the detection of low-frequency earthquakes by retraining only a local model.

Year: 2019

description: The purpose of the study is to find out the possible impact of politicization on implementing public policies in Addis Abeba City Administration. Both primary and secondary data were used. Descriptive ways of analysis were applied. To measure the overall situation of the implementation process citizens and public service employee's view was included. The poor implementation of public policies costs the country a lot. The finding of the research shows that the public is dissatisfied by poor implementation of policies and awkward service delivery of the public servants. On the other hand the public servants are not happy for working there. The Ande le Amest groups in the city administration, contents of training and procedures followed for giving promotion and other benefit shows high politicization. The different legislation including the constitution of the Republic of Ethiopia doesn't specify where the demarcation line should be for political appointment and other. Eventually the research recommended the need for clear legislation for the demarcation of politics and public service, the importance of awareness the public about the public office, the ruling party separate its political apparatus from public office, the need to build a career civil servant, the importance of following the merit procedures in giving promotion and the importance of need based training for public servants.

description: Doping asymmetry is a notable phenomenon with semiconductors and a particularly longstanding challenge limiting the applications of most wide-band-gap semiconductors, which are inherent of spontaneous heavy n- or p-type doping because of their extreme band edges. This study theoretically shows that by applying a proper external voltage on materials during their growth or doping processes, we can largely tune the band edges and consequently reverse the doping asymmetry in semiconductor thin films. We take zinc oxide as a touchstone and computationally demonstrate that this voltage-assisted-doping approach efficiently suppresses the spontaneous n-type defects by around four orders under three distinct growth conditions and successfully generates p-type zinc oxide up to the lowest acceptor levels. The proposed approach is insensitive to materials, growth conditions, or defects origins, and thus offers a general solution to the doping asymmetry in semiconductor thin films.

description: DNA and chromosomal damage in peripheral blood leukocytes of patients with coronary artery disease (CAD) were investigated by using the single cell gel electrophoresis assay /comet and cytokinesis- block micronucleus (CBMN) assays, respectively. The case-control study comprised patients with CAD (n = 46; average age 53.0 ± 1.27 y) undergoing treatment at local hospitals, and healthy age-and sex-matched controls (n = 19; average age 54.21 ± 0.91 y) from the general population. The results of the comet assay revealed that the mean values of DNA damage were significantly (p < 0.001) higher in CAD patients than in controls (Tail DNA% 11.55 ± 0.38 vs. 5.31 ± 0.44; Tail moment 6.17 ± 0.31 vs. 2.93 ± 0.21 AU; Olive tail moment 3.52 ± 0.23 vs. 1.25 ± 0.11 AU). The mean values of chromosomal damage were also significantly higher (p < 0.001) in CAD patients than in controls (Binucleated cells with MN-28.15 ± 1.18 vs. 18.16 ± 2.59; micronuclei 29.52 ± 1.21 vs. 18.68 ± 2.64, respectively) while nuclear division index (1.48 ± 0.01 vs. 1.63 ± 0.01) was significantly higher (p < 0.001) in controls. The results of the present study indicate that coronary artery disease patients had increased levels of both, unrepaired (DNA) and repaired (chromosomal) genetic damage which may be a pathological consequence of the disease and/or the drug-treatment. This accumulation of DNA/chromosomal damage is of concern as it can lead to the development of cancer with increased chances of morbidity and mortality in the CAD patients.

description: It is now a well-known fact that the correlations arising from local dichotomic measurements on an entangled quantum state may exhibit intrinsically non-classical features. In this paper we delve into a comprehensive study of random instances of such bipartite correlations. The main question we are interested in is: given a quantum correlation, taken at random, how likely is it that it is truly non-explainable by a classical model? We show that, under very general assumptions on the considered distribution, a random correlation which lies on the border of the quantum set is with high probability outside the classical set. What is more, we are able to provide the Bell inequality certifying this fact. On the technical side, our results follow from (i) estimating precisely the "quantum norm" of a random matrix, and (ii) lower bounding sharply enough its "classical norm", hence proving a gap between the two. Along the way, we need a non-trivial upper bound on the $\infty{\rightarrow}1$ norm of a random orthogonal matrix, which might be of independent interest.

description: Recent years have witnessed the great success of deep learning algorithms in the geoscience and remote sensing realm. Nevertheless, the security and robustness of deep learning models deserve special attention when addressing safety-critical remote sensing tasks. In this paper, we provide a systematic analysis of backdoor attacks for remote sensing data, where both scene classification and semantic segmentation tasks are considered. While most of the existing backdoor attack algorithms rely on visible triggers like squared patches with well-designed patterns, we propose a novel wavelet transform-based attack (WABA) method, which can achieve invisible attacks by injecting the trigger image into the poisoned image in the low-frequency domain. In this way, the high-frequency information in the trigger image can be filtered out in the attack, resulting in stealthy data poisoning. Despite its simplicity, the proposed method can significantly cheat the current state-of-the-art deep learning models with a high attack success rate. We further analyze how different trigger images and the hyper-parameters in the wavelet transform would influence the performance of the proposed method. Extensive experiments on four benchmark remote sensing datasets demonstrate the effectiveness of the proposed method for both scene classification and semantic segmentation tasks and thus highlight the importance of designing advanced backdoor defense algorithms to address this threat in remote sensing scenarios.

description: We take into consideration the evolution of particle size in a monodisperse aerosol population during activation and deactivation of cloud condensation nuclei (CCN). The phase portrait of the system derived through a weakly-nonlinear analysis reveals a saddle-node bifurcation and a cusp catastrophe. An analytical estimate of the activation timescale is derived through estimation of the time spent in the saddle-node bifurcation bottleneck. Numerical integration of the system portrays two types of activation/deactivation hystereses: one associated with the kinetic limitations on droplet growth when the system is far from equilibrium, and one occurring close to equilibrium and associated with the cusp catastrophe. The hysteretic behaviour close to equilibrium imposes stringent time-resolution constraints on numerical integration, particularly during deactivation.

description: The government of Ethiopia has launched economic reforms, financial liberalization measures and restructuring of public institutions with the aim of promoting a competitive environment and efficient services to the public. Gulelle sub _city is one of the ten sub – cities under Addis Ababa city government the name given during their new reform program in jun2002 However, the performance of the sub city in providing service is not in a position to meet the expectation of service users. There are repeated customer complains. Therefore, the major objective of this study is assessing the effect of service delivery on customer satisfaction in five sectors found under the sub _city, Addis Ababa. To attain this objective, questionnaire was designed categorized under five dimensions of the SERVEQUAL model. The sample consists of 400 respondents selected based on convenience sampling procedure. This study used quantitative research design and both primary and secondary data. The collected data was analyzed with the help of SPSS version 22.Correlation and multiple regressions were used to investigate the relationship between dependent and independent variables. Service quality has been defined as an overall judgment similar to attitudes towards the service and generally accepted as an antecedent of overall customer satisfaction (Zeithaml and Bitner, 1996). In general, the specific empirical findings emerged from the investigation: The five service quality dimensions that Service has positive and significant effect on customer satisfaction. Majority of customer are not satisfied with the current delivery system Therefore It is better to develop customer resolution when the sector fulfill customer needs .

description: We study anomalous dimensions of unprotected low twist operators in the four-dimensional $SU(N)$ $\mathcal{N}=4$ supersymmetric Yang-Mills theory. We construct a class of interpolating functions to approximate the dimensions of the leading twist operators for arbitrary gauge coupling $τ$. The interpolating functions are consistent with previous results on the perturbation theory, holographic computation and full S-duality. We use our interpolating functions to test a recent conjecture by the $\mathcal{N}=4$ superconformal bootstrap that upper bounds on the dimensions are saturated at one of the duality-invariant points $τ=i$ and $τ=e^{iπ/3}$. It turns out that our interpolating functions have maximum at $τ=e^{iπ/3}$, which are close to the conjectural values by the conformal bootstrap. In terms of the interpolating functions, we draw the image of conformal manifold in the space of the dimensions. We find that the image is almost a line despite the conformal manifold is two-dimensional. We also construct interpolating functions for the subleading twist operator and study level crossing phenomenon between the leading and subleading twist operators. Finally we study the dimension of the Konishi operator in the planar limit. We find that our interpolating functions match with numerical result obtained by Thermodynamic Bethe Ansatz very well. It turns out that analytic properties of the interpolating functions reflect an expectation on a radius of convergence of the perturbation theory.

description: Rejuvenating galaxies are unusual galaxies that fully quench and then subsequently experience a "rejuvenation" event to become star-forming once more. Rejuvenation rates vary substantially in models of galaxy formation: 10%-70% of massive galaxies are expected to experience rejuvenation by z = 0. Measuring the rate of rejuvenation is therefore important for calibrating the strength of star formation feedback mechanisms. However, these observations are challenging because rejuvenating systems blend in with normal star-forming galaxies in broadband photometry. In this paper, we use the galaxy spectral energy distribution (SED)-fitting code Prospector to search for observational markers that distinguish normal star-forming galaxies from rejuvenating galaxies. We find that rejuvenating galaxies have smaller Balmer absorption line equivalent widths (EWs) than star-forming galaxies. This is analogous to the well-known "K + A" or post-starburst galaxies, which have strong Balmer absorption due to A-stars dominating the light: in this case, rejuvenating systems have a lack of A-stars, instead resembling "O - A" systems. We find star-forming galaxies that have H$β$, H$γ$, and/or H$δ$ absorption EWs $\lesssim 3$Å corresponds to a highly pure selection of rejuvenating systems. Interestingly, while this technique is highly effective at identifying mild rejuvenation, "strongly" rejuvenating systems remain nearly indistinguishable from star-forming galaxies due to the well-known stellar outshining effect. We conclude that measuring Balmer absorption line EWs in star-forming galaxy populations is an efficient method to identify rejuvenating populations, and discuss several techniques to either remove or resolve the nebular emission which typically lies on top of these absorption lines.

description: This survey investigates the effect of county of origin on product purchasing intention in young Ethiopian consumer's perspective. . The main objective of this study was to investigate the effect of country of origin on product purchase intention in the case of Ethiopian young consumers. To investigate the effect various question raised like what is the perception of Ethiopian young consumer's on product's COO? The survey was conducted using self-administrated questionnaires in Universities in Addis Ababa. The study followed Sequential Mixed research philosophy where more of quantitative in nature which is, especially it used predetermined and highly structured data collection techniques under this study. The study was used a casual research design since causal studies helps the researcher to seek to discover the effect that a variable(s) has on another. The study used non-probability design in the form of convenience sampling was used since this enables the researcher to have the freedom to choose to pick university students from Addis Ababa. Data analysis is carried out using the Statistical Package for Social Science (SPSS) version 23. This study focus on the following dimensions of independent variables, product attributes (quality and technological excellence, product superiority and trust, product class and knowledge, ethnocentrism and xenocentrism) to influence purchase intentions of young consumers in Ethiopia which is a dependent Variables which was measured in a five pint likert scale. The results of the study show that COO is considered as information that affects consumers' purchasing decision in terms of their perception toward the products attributes as well as their overall evaluation of the product. It is found that Ethiopian young consumers who exhibit a high degree of ethnocentrism tend to have a more positive perception of Ethiopia as a country and products that are domestically made. One of the significant findings of the study is that a favorable attitude towards Ethiopian and domestic products (ethnocentric orientation) among young Ethiopian consumers do not necessarily lead to a negative perception of foreign countries and products. This assumption can be supported by the fact that Ethiopian young consumers are allured with well-known foreign brands and some of them rate products of developed countries higher than those from Ethiopia and similar other developing countries.

description: Diskursive Koordinierung findet in dezentralisierten Arbeitsstrukturen zumeist in "Meetings" statt. Insbesondere mit dem Anspruch der Entscheidungsfindung ist das Meeting jedoch strukturell überfordert. Der Artikel zeigt auf, wie in dem Gefüge von Informationsüberflutung, unklaren Entscheidungskompetenzen, Entscheidungsangst sowie Absicherungs- und Rechtfertigungskultur das Meeting vom Entscheidungsforum zum Ort der immerwährenden Problemgenese mutiert: Der Wunsch nach perfekt rationalen Entscheidungen führt zu Handlungsblockaden. Die Autorinnen plädieren stattdessen für eine effizientere Entscheidungsfindung durch die Nutzung informeller Kooperation.

description: Geschlechterverhältnisse auf dem Arbeitsmarkt sind Gegenstand zahlreicher Debatten und im Zuge eines sozialen Wandels in das kollektive Bewusstsein gerückt. Der Arbeitsbereich „Bibliothek“ ist ein frauendominiertes Feld mit einem Frauenanteil von über 74%. Interessanterweise liegen jedoch keine aktuellen umfassenden statistischen Auswertungen über Frauen in Leitungspositionen an deutschen Bibliotheken vor. Vor dem Hintergrund der Leitfrage, wie hoch der Anteil von Frauen in der obersten Hierarchieebene an deutschen Bibliotheken ist, präsentiert der vorliegende Artikel die Ergebnisse einer quantitativen Erhebung. Diese werden in einen theoretischen Kontext eingebettet, in dem Forschungsaspekte aus verschiedenen wissenschaftlichen Disziplinen, wie der Geschlechter- oder Organisationsforschung, vorangestellt werden. Dieser Beitrag beruht auf einer Masterarbeit aus dem Jahr 2021 am Institut für Bibliotheks- und Informationswissenschaft der Humboldt Universität zu Berlin.
description: Gender proportions in the employment sector are the subject of numerous debates and have moved into the collective awareness as a result of social change. The "library" work area is a female-dominated field with a share of women of over 74%. Interestingly, however, there are no current detailed statistical evaluations of women in management positions in German libraries. Against the background of the main question regarding the proportion of women at the top hierarchical level in German libraries, this article presents the results of a quantitative survey. These are embedded in a theoretical context in which research aspects from various scientific disciplines, such as gender or organizational research, are presented. This article is based on a master's thesis written in 2021 at the Institute of Library and Information Science at the Humboldt Universität zu Berlin.

description: Trotz der zunehmenden Angleichung der Lebenspläne von Frauen und Männern wird in der Arbeitsmarkt- und Berufsforschung von einer geschlechtsspezifischen Segregation des Arbeitsmarktes gesprochen. Am Beispiel einer Gelegenheitsstichprobe von 920 Erwerbstätigen in Vollzeitarbeitsverhältnissen wird gefragt, ob Geschlechtseffekte existieren in der Lernhaltigkeit der Arbeitssituation als einem Prädiktor arbeitsimmanenter Kompetenzentwicklung, in der Beschaffenheit beruflicher Handlungskompetenz, die über das Selbstkonzept mit Hilfe standardisierter Analyseinstrumente erfasst wird, und bezüglich des Anteils von Personen mit Führungsfunktion. Die Befunde enthalten kleine, aber signifikante Geschlechtseffekte in den Ausprägungen des Selbstkonzepts beruflicher Kompetenz zugunsten der Männer und sie belegen, dass Männer häufiger Führungsfunktionen ausüben. Es gibt keine Geschlechtseffekte bei der Einschätzung der Lernhaltigkeit der Arbeitssituation.

description: Cloud cover at the planetary limb of water-rich Earth-like planets is likely to weaken chemical signatures in transmission spectra, impeding attempts to characterize these atmospheres. However, based on observations of Earth and solar system worlds, exoplanets with atmospheres should have both short-term weather and long-term climate variability, implying that cloud cover may be less during some observing periods. We identify and describe a mechanism driving periodic clear sky events at the terminators in simulations of tidally locked Earth-like planets. A feedback between dayside cloud radiative effects, incoming stellar radiation and heating, and the dynamical state of the atmosphere, especially the zonal wavenumber-1 Rossby wave identified in past work on tidally locked planets, leads to oscillations in Rossby wave phase speeds and in the position of Rossby gyres and results in advection of clouds to or away from the planet's eastern terminator. We study this oscillation in simulations of Proxima Centauri b, TRAPPIST 1-e, and rapidly rotating versions of these worlds located at the extreme inner edge of their stars' habitable zones. We simulate time series of the transit depths of the 1.4 μm water feature and 2.7 μm carbon dioxide feature. The impact of atmospheric variability on the transmission spectra is sensitive to the structure of the dayside cloud cover and the location of the Rossby gyres, but none of our simulations have variability significant enough to be detectable with current methods.

Search for dark matter produced in association with a single top quark and an energetic $W$ boson in $\sqrt{s}=$ 13 TeV $pp$ collisions with the ATLAS detector

description: This paper presents a search for dark matter, $χ$, using events with a single top quark and an energetic $W$ boson. The analysis is based on proton-proton collision data collected with the ATLAS experiment at $\sqrt{s}=$ 13 TeV during LHC Run 2 (2015-2018), corresponding to an integrated luminosity of 139 fb$^{-1}$. The search considers final states with zero or one charged lepton (electron or muon), at least one $b$-jet and large missing transverse momentum. In addition, a result from a previous search considering two-charged-lepton final states is included in the interpretation of the results. The data are found to be in good agreement with the Standard Model predictions and the results are interpreted in terms of 95% confidence-level exclusion limits in the context of a class of dark matter models involving an extended two-Higgs-doublet sector together with a pseudoscalar mediator particle. The search is particularly sensitive to on-shell production of the charged Higgs boson state, $H^{\pm}$, arising from the two-Higgs-doublet mixing, and its semi-invisible decays via the mediator particle, $a$: $H^{\pm} \rightarrow W^\pm a (\rightarrow χχ)$. Signal models with $H^{\pm}$ masses up to 1.5 TeV and $a$ masses up to 350 GeV are excluded assuming a tan$β$ value of 1. For masses of $a$ of 150 (250) GeV, tan$β$ values up to 2 are excluded for $H^{\pm}$ masses between 200 (400) GeV and 1.5 TeV. Signals with tan$β$ values between 20 and 30 are excluded for $H^{\pm}$ masses between 500 and 800 GeV.
