description: COMPASS is a fixed-target experiment at the CERN SPS that studies the spectrum of light-quark hadrons. In 2009, it collected a large dataset using a $190\,$GeV$/c$ positive hadron beam impinging on a liquid-hydrogen target in order to measure the central exclusive production of light scalar mesons. One of the goals is the search for so-called glueballs, which are hypothetical meson-like objects without valence-quark content. We study the decay of neutral resonances by selecting centrally produced pion pairs from the COMPASS dataset. The angular distributions of the two pseudoscalar mesons are decomposed in terms of partial waves, where particular attention is paid to the inherent mathematical ambiguities. The large dataset allows us to perform a detailed analysis in bins of the two squared four-momentum transfers carried by the exchange particles in the reaction. Possible parameterisations of the mass dependence of the partial-wave amplitudes in terms of resonances are also discussed.

description: Arrays of fluorescent nanoparticles are highly sought after for applications in sensing and nanophotonics. Here we present a simple and robust method of assembling fluorescent nanodiamonds into macroscopic arrays. Remarkably, the yield of this directed assembly process is greater than 90% and the assembled patterns withstand ultra-sonication for more than three hours. The assembly process is based on covalent bonding of carboxyl to amine functional carbon seeds and is applicable to any material, and to non-planar surfaces. Our results pave the way to directed assembly of sensing and nanophotonics devices.

description: After leading to a new axiomatic derivation of quantum theory, the new informational paradigm is entering the domain of quantum field theory, suggesting a quantum automata framework that can be regarded as an extension of quantum field theory to including an hypothetical Planck scale, and with the usual quantum field theory recovered in the relativistic limit of small wave-vectors. Being derived from simple principles (linearity, unitarity, locality, homogeneity, isotropy, and minimality of dimension), the automata theory is quantum ab-initio, and does not assume Lorentz covariance and mechanical notions. Being discrete it can describe localized states and measurements (unmanageable by quantum field theory), solving all the issues plaguing field theory originated from the continuum. These features make the theory an ideal framework for quantum gravity, with relativistic covariance and space-time emergent solely from the interactions, and not assumed a priori. The paper presents a synthetic derivation of the automata theory, showing how from the principles lead to a description in terms of a quantum automaton over a Cayley graph of a group. Restricting to Abelian groups we show how the automata recover the Weyl, Dirac and Maxwell dynamics in the relativistic limit. We conclude with some new routes about the more general scenario of non-Abelian Cayley graphs.

description: Despite the long history of dislocation-phonon interaction studies, there are many problems that have not been fully resolved during this development. These include an incompatibility between a perturbative approach and the long-range nature of a dislocation, the relation between static and dynamic scattering, and the nature of dislocation-phonon resonance. Here by introducing a fully quantized dislocation field, the "dislon"[1], a phonon is renormalized as a quasi-phonon, with shifted quasi-phonon energy, and accompanied by a finite quasi-phonon lifetime that is reducible to classical results. A series of outstanding legacy issues including those above can be directly explained within this unified phonon renormalization approach. In particular, a renormalized phonon naturally resolves the decades-long debate between dynamic and static dislocation-phonon scattering approaches.

description: Stars do not form in isolation but together with other stars, often in a clustered environment. During the dynamical evolution of these environments, the stars in the region will interact with each other. These encounters will affect not only the stars but also any planetary systems that are in the process of forming around them. Many typical fly-by simulations focus on a single fly-by event's effect on a planetary system. However, during the early dynamical evolution of the birth cluster, dynamical binaries can form quickly from two single stars. We find these dynamical binaries in many of our simulations, but their effect on planetary systems that have formed around their initially single stars is largely unexplored. In this talk, I will present results from young star cluster N-body simulations showing how dynamical binaries can be formed and destroyed again. I will then show isolated planet system simulations and present results focussing on the differences in the orbital parameters of planetary systems from either of the interaction scenarios. I will show how dynamical binaries can accelerate the disruption of planetary systems and compare the differences in the resulting planetary architectures after 100 Myr.

description: The problem of estimating sparse eigenvectors of a symmetric matrix attracts a lot of attention in many applications, especially those with high dimensional data set. While classical eigenvectors can be obtained as the solution of a maximization problem, existing approaches formulate this problem by adding a penalty term into the objective function that encourages a sparse solution. However, the resulting methods achieve sparsity at the expense of sacrificing the orthogonality property. In this paper, we develop a new method to estimate dominant sparse eigenvectors without trading off their orthogonality. The problem is highly non-convex and hard to handle. We apply the MM framework where we iteratively maximize a tight lower bound (surrogate function) of the objective function over the Stiefel manifold. The inner maximization problem turns out to be a rectangular Procrustes problem, which has a closed form solution. In addition, we propose a method to improve the covariance estimation problem when its underlying eigenvectors are known to be sparse. We use the eigenvalue decomposition of the covariance matrix to formulate an optimization problem where we impose sparsity on the corresponding eigenvectors. Numerical experiments show that the proposed eigenvector extraction algorithm matches or outperforms existing algorithms in terms of support recovery and explained variance, while the covariance estimation algorithms improve significantly the sample covariance estimator.

The impact of stellar activity on the detection and characterization of exoplanetary atmospheres: Challenges and opportunities
Creators: name: Rackham, Benjamin V.
Publisher: name: Zenodo
Year: 2023

description: Transmission spectroscopy, a method for studying exoplanetary atmospheres by measuring the wavelength-dependent radius of a planet as it transits its star, relies on a precise understanding of the spectrum of the star being occulted. However, stars are not homogeneous, constant light sources but have temporally evolving photospheres and chromospheres with inhomogeneities like spots, faculae, and plages. Study Analysis Group 21 (SAG21) of NASA’s Exoplanet Exploration Program Analysis Group (ExoPAG) was organized to study the effect of stellar photospheric heterogeneity on low-resolution transmission spectroscopy. This SAG brought together an interdisciplinary team of more than 100 scientists, with observers and theorists from the heliophysics, stellar astrophysics, planetary science, and exoplanetary atmosphere research communities, to study the current needs that can be addressed in this context to make the most of transit studies from HST, JWST, and more. Here I report on the main conclusions of this analysis, highlighting outstanding challenges, mitigation efforts underway, and connections to high-resolution observations. The analysis produced 14 findings, which fall into three science themes that encompass (1) the Sun as the stellar benchmark, (2) surface heterogeneities of other stars, and (3) mapping stellar knowledge to transit studies. Addressing the needs identified through this large community effort will ensure that we can optimally leverage transmission spectra in light of stellar activity.

description: Characterising exoplanets and their atmospheres is a crucial step in the quest for life outside of Earth. In favourable cases, we can directly observe the light emitted from an exoplanet's dayside and utilise high-resolution spectroscopy and cross-correlation techniques to detect the molecular and atomic species present in its atmosphere.
 Recently, the transmission spectra of WASP-76 b revealed an asymmetric signature of neutral iron (Ehrenreich et al. 2020, Kesseli & Snellen 2021). The authors proposed a scenario where iron condensed on the nightside, and predicted that this species would be amenable to detection on the dayside through thermal emission spectroscopy. To test this hypothesis, we analysed four time-series emission spectra of WASP-76 b obtained with the high-resolution ESPRESSO spectrograph. The dayside observations were carried out before and after the secondary transit (two epochs of each), probing the eastern and western hemispheres of the tidally locked planet. We extracted the exoplanet's spectra and cross-correlated them with an iron mask created for an ultra-hot Jupiter with a temperature inversion in its atmosphere.
 We found 3-sigma detections of neutral iron on the dayside of WASP-76 b in at least two epochs. The discrepancy between datasets is examined and we propose explanations for the lack of detection during the other two epochs.

description: A family of algebraic curves covering a projective variety $X$ is called a web of curves on $X$ if it has only finitely many members through a general point of $X$. A web of curves on $X$ induces a web-structure, in the sense of local differential geometry, in a neighborhood of a general point of $X$. We study how the local differential geometry of the web-structure affects the global algebraic geometry of $X$. Under two geometric assumptions on the web-structure, the pairwise non-integrability condition and the bracket-generating condition, we prove that the local differential geometry determines the global algebraic geometry of $X$, up to generically finite algebraic correspondences. The two geometric assumptions are satisfied, for example, when $X \subset {\bf P}^N$ is a Fano submanifold of Picard number 1, and the family of lines covering $X$ becomes a web. In this special case, we have a stronger result that the local differential geometry of the web-structure determines $X$ up to biregular equivalences. As an application, we show that if $X, X' \subset {\bf P}^N, \dim X' \geq 3,$ are two such Fano manifolds of Picard number 1, then any surjective morphism $f: X \to X'$ is an isomorphism.

The CARMENES search for exoplanets around M dwarfs: Line-by-line sensitivity to activity in M dwarfs
Creators: name: Lafarga, Marina
Publisher: name: Zenodo
Year: 2023

description: Stellar activity poses one of the main obstacles for the detection and characterisation of exoplanets around cool stars, as it deforms the absorption line profiles of stellar spectra creating signals that can hide or mimic the presence of companions. A wide variety of techniques are being developed with the aim of disentangling signals of stellar and planetary origins. These range from the decorrelation or modelling of the activity signals in the radial velocity (RV) time series, to the RV extraction using carefully selected wavelength regions of the stellar spectrum which are less affected by activity. In this work, we analyse the effects of activity on individual absorption features present on the optical spectra of several active M dwarf stars observed with the CARMENES high-resolution spectrograph. By studying the correlations between the individual line RVs and activity indicators, we are able to classify the observed lines according to their sensitivity to activity. This allows us to select differently affected lines and use them to compute RVs for which we mitigate or enhance the activity signal to varying degrees. We also observe that the same lines on similar stars show different sensitivities to activity, suggesting the generalisation of a line list a challenging endeavour.

description: We report on an analysis of high-precision, multi-colour photometric observations of the rapidly-oscillating Ap (roAp) star $α$ Cir. These observations were obtained with the BRITE-Constellation, which is a coordinated mission of five nanosatellites that collects continuous millimagnitude-precision photometry of dozens of bright stars for up to 180 days at a time in two colours (Johnson B and R). BRITE stands for BRight Target Explorer. The object $α$ Cir is the brightest roAp star and an ideal target for such investigations, facilitating the determination of oscillation frequencies with high resolution. This star is bright enough for complementary interferometry and time-resolved spectroscopy. Four BRITE satellites observed $α$ Cir for 146 d or 33 rotational cycles. Phasing the photometry according to the 4.4790 d rotational period reveals qualitatively different light variations in the two photometric bands. The phased red-band photometry is in good agreement with previously-published WIRE data, showing a light curve symmetric about phase 0.5 with a strong contribution from the first harmonic. The phased blue-band data, in contrast, show an essentially sinusoidal variation. We model both light curves with Bayesian Photometric Imaging, which suggests the presence of two large-scale, photometrically bright (relative to the surrounding photosphere) spots. We also examine the high-frequency pulsation spectrum as encoded in the BRITE photometry. Our analysis establishes the stability of the main pulsation frequency over the last 20 years, confirms the presence of frequency f7, which was not detected (or the mode not excited) prior to 2006, and excludes quadrupolar modes for the main pulsation frequency.

Patient’s perspectives and uptake of preimplantation genetic testing for polygenic conditions
Creators: name: Goldshteyn, Sarah Elizabeth
Publisher: name: No Publisher Supplied
Year: 2023

description: Preimplantation genetic testing (PGT) is an essential tool for Assisted Reproductive Technology (ART) and is commonly used in conjunction with in vitro fertilization (IVF). PGT for polygenic conditions (PGT-P) is a relatively new technology that analyzes embryos for single nucleotide polymorphisms (SNPs) associated with polygenic conditions. This technology is a validated tool and can be applied to embryos. Its primary utility is for relative risk reduction when selecting an embryo to transfer. This research analyzes factors that motivate patients to pursue PGT-P and if pregnancy outcomes alter decision regret and patient anxiety. Additionally, this study aimed to determine if uptake rates of PGT-P varied dependent on patient ancestry. It was found that using PGT-P was useful for patients undergoing IVF. Family history of polygenic conditions as well as perception of disease severity seem to be correlated with importance of decision-making factors. Decision-regret regarding PGT-P was relatively low and varied based on pregnancy outcomes. Anxiety levels at receipt of PGT-P results were low and higher at embryo selection. Finally, uptake rates of PGT-P do vary based on ancestry, however, uptake rates based on ancestry are comparable to other ART procedures.

description: We use a radio-frequency $^{85}$Rb alkali-vapor cell magnetometer based on a paraffin-coated cell with long spin-coherence time and a small, low-inductance driving coil to create highly resolved conductivity maps of different objects. We resolve sub-mm features in conductive objects, we characterize the frequency response of our technique, and by operating at frequencies up to 250 kHz we are able to discriminate between differently conductive materials based on the induced response. The method is suited to cover a wide range of driving frequencies and can potentially be used for detecting non-metallic objects with low DC conductivity.

The hot Neptune WASP-166 b with ESPRESSO: A blue-shifted tentative water signal constrains the presence of clouds
Creators: name: Lafarga, Marina
Publisher: name: Zenodo
Year: 2023

description: With high-resolution spectroscopy we can study exoplanet atmospheres and learn about their chemical composition, temperature profiles, and presence of clouds and winds, mainly in hot, giant planets. State-of-the-art instrumentation is pushing these studies towards smaller exoplanets. Of special interest are the few planets in the Neptune desert, a lack of Neptune-size planets in close orbits around their hosts. Studying these can provide insight to their planetary formation and evolution, and shed light on the origin of the desert. Here, we assess the presence of water in one such planet, the bloated super-Neptune WASP-166 b, which orbits an F9-type star in a short orbit of 5.4 days. Despite its close-in orbit, WASP-166 b preserved its atmosphere, making it a benchmark target for exoplanet atmosphere studies in the desert. We analyse two transits observed in the visible with ESPRESSO. We clean the spectra from the Earth's telluric absorption via principal component analysis, which is crucial to the search for water in exoplanets. We use a cross-correlation-to-likelihood mapping to simultaneously estimate limits on the abundance of water and the altitude of a cloud layer, which points towards a low water abundance and/or high clouds. We tentatively detect a water signal blue-shifted about 5 km/s from the planetary rest frame. This is the first time water has potentially been observed in the optical with ESPRESSO. Injection and retrieval of model spectra show that a solar-composition, cloud-free atmosphere would be detected at high significance. This is only possible in the visible due to the capabilities of ESPRESSO and the collecting power of the VLT. This work provides further insight on the Neptune desert planet WASP-166 b, scheduled to be observed in the near-infrared with JWST, which will provide further constraints on the presence of molecules such as water.

description: We evaluate the extent of the regions within the $α$ Centauri AB star system where small planets are able to orbit for billion-year timescales, and we calculate the positions on the sky plane where planets on stable orbits about either stellar component may appear. We confirm the qualitative results of Wiegert and Holman (AJ 113, 1445, 1997) regarding the approximate size of the regions of stable orbits, which are larger for retrograde orbits relative to the binary than for prograde orbits. Additionally, we find that mean motion resonances with the binary orbit leave an imprint on the limits of orbital stability, and the effects of the Lidov-Kozai mechanism are also readily apparent.

description: Image stitching algorithms often adopt the global transformation, such as homography, and work well for planar scenes or parallax free camera motions. However, these conditions are easily violated in practice. With casual camera motions, variable taken views, large depth change, or complex structures, it is a challenging task for stitching these images. The global transformation model often provides dreadful stitching results, such as misalignments or projective distortions, especially perspective distortion. To this end, we suggest a perspective-preserving warping for image stitching, which spatially combines local projective transformations and similarity transformation. By weighted combination scheme, our approach gradually extrapolates the local projective transformations of the overlapping regions into the non-overlapping regions, and thus the final warping can smoothly change from projective to similarity. The proposed method can provide satisfactory alignment accuracy as well as reduce the projective distortions and maintain the multi-perspective view. Experiments on a variety of challenging images confirm the efficiency of the approach.

description: We report detailed measurements of the temperature dependence of the lower critical field Hc1 in the stripe ordered La1.6-xNd0.4SrxCuO4 (x = 0.10 and 0.15) superconductors. It is found that Hc1(T) of the samples increase with decreasing temperature and show an negative curvature below Tc. The penetration depth λ(T) estimated from Hc1(T) data satisfies a linear temperature dependence behavior below Tc/2, which is consistent with that in a superconductor with d-wave symmetry of the energy gap and the upward trend in Hc1(T) may be due to the cooperation of the hole and election pockets arising from the reconstruction of the Fermi surface, which contributes to illustrating the Fermi surface reconstruction in La1.6-xNd0.4SrxCuO4.

description: Human beings cannot exist without communication. This paper, therefore, focused on the indigenous communication system of the Oromo community of Haramaya district, East Hararghe Zone, Oromia Regional State. The theoretical frameworks used were social learning theory and multistep flow model of communication. While the sampling technique was purposive, the data were collected through non-participant observation, focus group discussion of the elders and youths in the study area, and interview held with selected elders of the district. The finding showed that forms of indigenous communication in the study area were Og-afaanii/oral literature (folksongs, proverbs, riddles, folk stories), extramundane communication, color scheme, obejectifics, dhaamsa/messenger system, indigenous organizations like mosque and afooshaa/edir/mandandraa (traditional associations), signals, symbolic display, deliberate instruction, direct observation, and informal channels like waarii (one another‟s visiting at any time), aborade (one another‟s visiting during fasting season). In addition, the finding proved that these forms of indigenous communication had their own actors such as daminoota (clan leaders) and roles such as to entertain and socialize the community members, to express and educate stories, and cultural values and disseminate social, economic, and political concerns of the community. However, the credibility of these indigenous communication forms is decelerating though they are still in use. It is, therefore, recommended that governmental and nongovernmental organizations, educated members of the community, and families should stress on the indigenous communication system when they want to reach the community and preserve the system for future generation.

A Critical Discourse Analysis of Gendered Representations in Afaan Oromoo Textbook
Creators: name: Barkessa, Adugna
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2020

description: The objectives of this paper are to describe texts and illustrations used to represent female and male genders in grade 11 Afaan Oromoo textbook, to examine messages of the representations and to explain the nexus between ideology and power in the representations of female and male actors in the textbook. The textbook was selected from the textbook series introduced for grades 9-12 in 2012 using a simple random sampling technique. Female and male genders-related texts and illustrations were collected from the textbook through document analysis. The data were analyzed using qualitative content analysis in conjunction with critical discourse analysis following Fairclough‟s (1992) model of analytical framework. The findings show that the textbook was dominated in most and monopolized in some parts by texts and illustrations that favor male actors. Binary oppositions - weak vs. strong, illiterate vs. literate, skilled vs. less skilled, rich vs. poor, small vs. big, misleading vs. truthful, etc. were used to represent female and male actors, respectively. These descriptors convey negative messages about female and positive messages about male actors. The messages show asymmetrical power relations between the two sexes. This can promote stereotypical thinking, may lower girls‟ participation in classroom activities and can deter their efforts from competing with boys in education. The textbook needs to be revised balancing verbal and non-verbal representations and roles of female and male genders. As an immediate intervention, Oromia Educational Bureau needs to give short term on job training for teachers, writers/ editors on gender parity in education.

description: This action research was conducted to reduce the effect of handout-dependent-learning on instructional time. Descriptive research design was used. In preliminary survey, seven instructors at School of Biological Sciences and Biotechnology, three duplication staffs and 46 third-year biology students were selected by purposive, systematic random and clustering random techniques, respectively. In-depth interview was used to collect data from the instructors, head of university duplication service and 2 support staffs. Questionnaire was used to collect data from the students. In action research plan, Fundamentals of Biotechnology and Introduction to Immunology and Cytogenetics were selected. National Center for Biotechnology Information (NCBI), Science Direct and Springer online databases and reference books with brief notes, and detailed notes were selected for implementation of action plan. Observations, feedbacks and tests were used for data collection. Quantitative data were analyzed by measured values, frequencies or percentages. Qualitative data were analyzed by identifying and describing themes or categories came up from the respondents‟ responses. The preliminary survey showed that handout duplication took at least three weeks and students had the habit of waiting handout to start reading courses. The implemented online databases and reference books along with brief notes showed the coverage of the selected units within the curricular allocated time. The implementation of detailed notes showed consumption of an additional 2-hour instructional time. The study implied that students should start reading courses using available alternatives to handout rather than waiting for handout in order to reduce overconsumption of instructional time in Haramaya University classrooms context.

description: In the frame of a systematic study of charged particle production routes of medically relevant radionuclei, the excitation function for indirect production of $^{178m}$Ta through $^{nat}$Hf($α$,xn)$^{178-178m}$Ta nuclear reaction was measured for the first time up to 40 MeV. In parallel, the side reactions $^{nat}$Hf($α$,x)$^{179,177,176,175}$W, $^{183,182,178g,177,176,175}$Ta, $^{179m,177m,175}$Hf were also assessed. Stacked foil irradiation technique and $γ$-ray spectrometry were used. New experimental cross section data for the $^{nat}$Ta(d,xn)$^{178}$W reaction are also reported up to 40 MeV. The measured excitation functions are compared with the results of the ALICE-IPPE, and EMPIRE nuclear reaction model codes and with the TALYS 1.4 based data in the TENDL-2013 library. The thick target yields were deduced and compared with yields of other charged particle ((p,4n), (d,5n) and ($^3$He,x)) production routes for $^{178}$W.

description: Effective leaders are enablers that directly point to competent and committed employees. The purpose of this study was to examine the relationship between leadership styles and academic staff organizational commitment. To realize the study, descriptive correlational design was undertaken.. This design was used to compare the three leadership styles along with correlation, regression and path analysis to investigate the relationship and extent of the predictors on the outcome variables. Thus, a total of 147 Dire Dawa University academic staff participated as sample population using stratified random sampling technique. The result of Pearson correlation indicates organizational commitment of the academic staff had a statistical significant positive association with both transformational and transactional leadership styles. Nevertheless, laissez-faire leadership style had no a statistically significant relationship with organizational commitment of the academic staff. On the other hand, stepwise multiple regression results showed organizational commitment dimensions were explained by both transformational and transactional leadership facets. On the bases of the finding, it is recommended that higher level administration of the University should develop the leadership skill of the department chairs through different leadership development initiatives to increase the organizational commitment of the academic staff. Further research is also needed to identify other factors that could increase the academic staff organizational commitment.

description: Manual identification of fission tracks has practical problems, such as variation due to observer-observation efficiency. An automatic processing method that could identify fission tracks in a photomicrograph could solve this problem and improve the speed of track counting. However, separation of non-trivial images is one of the most difficult tasks in image processing. Several commercial and free softwares are available, but these softwares are meant to be used in specific images. In this paper, an automatic method based on starlet wavelets is presented in order to separate fission tracks in mineral photomicrographs. Automatization is obtained by Matthews correlation coefficient, and results are evaluated by precision, recall and accuracy. This technique is an improvement of a method aimed at segmentation of scanning electron microscopy images. This method is applied in photomicrographs of epidote phenocrystals, in which accuracy higher than 89% was obtained in fission track segmentation, even for difficult images. Algorithms corresponding to the proposed method are available for download. Using the method presented here, an user could easily determine fission tracks in photomicrographs of mineral samples.
