description: Context: Low- and intermediate-mass stars lose most of their stellar mass at the end of their lives on the asymptotic giant branch (AGB). Determining gas and dust mass-loss rates (MLRs) is important in quantifying the contribution of evolved stars to the enrichment of the interstellar medium. Aims: Attempt to, for the first time, spectrally resolve CO thermal line emission in a small sample of AGB stars in the Large Magellanic Cloud. Methods: ALMA was used to observe 2 OH/IR stars and 4 carbon stars in the LMC in the CO J= 2-1 line. Results: We present the first measurement of expansion velocities in extragalactic carbon stars. All four C-stars are detected and wind expansion velocities and stellar velocities are directly measured. Mass-loss rates are derived from modelling the spectral energy distribution and Spitzer/IRS spectrum with the DUSTY code. Gas-to-dust ratios are derived that make the predicted velocities agree with the observed ones. The expansion velocities and MLRs are compared to a Galactic sample of well-studied relatively low MLRs stars supplemented with "extreme" C-stars that have properties more similar to the LMC targets. Gas MLRs derived from a simple formula are significantly smaller than derived from the dust modelling, indicating an order of magnitude underestimate of the estimated CO abundance, time-variable mass loss, or that the CO intensities in LMC stars are lower than predicted by the formula derived for Galactic objects. This could be related to a stronger interstellar radiation field in the LMC. Conclusions: Although the LMC sample is small and the comparison to Galactic stars is non-trivial because of uncertainties in their distances it appears that for C stars the wind expansion velocities in the LMC are lower than in the solar neighbourhood, while the MLRs appear similar. This is in agreement with dynamical dust-driven wind models.

description: Process mining is a research area focusing on the design of algorithms that can automatically provide insights into business processes. Among the most popular algorithms are those for automated process discovery, which have the ultimate goal to generate a process model that summarizes the behavior recorded in an event log. Past research had the aim to improve process discovery algorithms irrespective of the characteristics of the input log. In this paper, we take a step back and investigate the connection between measures capturing characteristics of the input event log and the quality of the discovered process models. To this end, we review the state-of-the-art process complexity measures, propose a new process complexity measure based on graph entropy, and analyze this set of complexity measures on an extensive collection of event logs and corresponding automatically discovered process models. Our analysis shows that many process complexity measures correlate with the quality of the discovered process models, demonstrating the potential of using complexity measures as predictors of process model quality. This finding is important for process mining research, as it highlights that not only algorithms, but also connections between input data and output quality should be studied.

description: Using a theoretical model, we track the thermal evolution of a cooling neutron star crust after an accretion induced heating period with the goal of constraining the crustal parameters. We present for the first time a crust cooling model $-\text{ } NSCool\text{ } -$ that takes into account detailed variability during the full outburst based on the observed light curve. We apply our model to KS 1731-260. The source was in outburst for $\sim$12 years during which it was observed to undergo variations on both long (years) and short (days-weeks) timescales. Our results show that KS 1731-260 does not reach a steady state profile during the outburst due to fluctuations in the derived accretion rate. Additionally, long time-scale outburst variability mildly affects the complete crust cooling phase, while variations in the final months of the outburst strongly influence the first $\sim$40 days of the calculated cooling curve. We discuss the consequences for estimates of the neutron star crust parameters, and argue that detailed modelling of the final phase of the outburst is key to constraining the origin of the shallow heat source.

description: This paper presents an approach for Evoked Expressions from Videos (EEV) challenge, which aims to predict evoked facial expressions from video. We take advantage of pre-trained models on large-scale datasets in computer vision and audio signals to extract the deep representation of timestamps in the video. A temporal convolution network, rather than an RNN like architecture, is used to explore temporal relationships due to its advantage in memory consumption and parallelism. Furthermore, to address the missing annotations of some timestamps, positional encoding is employed to ensure continuity of input data when discarding these timestamps during training. We achieved state-of-the-art results on the EEV challenge with a Pearson correlation coefficient of 0.05477, the first ranked performance in the EEV 2021 challenge.

Domain Variations for Moving Boundary Problems

Subjects: subject: Analysis of PDEs (math.AP)

subject: 35R37

description: In the past few decades maximal regularity theory has successfully been applied to moving boundary problems. The basic idea is to reduce the system with varying domains to one in a fixed domain. This is done by a transformation (the so-called Hanzawa transformation) and yields a typically nonlocal and nonlinear coupled system of (evolution) equations. Well-posedness results can then often be established as soon as it is proved that the relevant linearization is the generator of an analytic semigroup or admits maximal regularity. To implement this program, it is necessary to somehow parametrize to space of boundaries/domains (typically the space of compact hypersurfaces $Γ$ in $\mathbb{R}^n$, in the Euclidean setting). This has traditionally been achieved by means of the already mentioned Hanzawa transformation. The approach, while successful, requires the introduction of a smooth manifold $Γ_\infty$ close to the manifold $Γ_0$ in which one cares to linearize. This prevents one to use coordinates in which $Γ_0$ lies at their "center". As a result formulæ tend to contain terms that would otherwise not be present were one able to linearize in a neighborhood emanating from $Γ_0$ instead of from $Γ_\infty$. In this paper it is made use of flows (curves of diffeomorphisms) to obtain a general form of the relevant linearization in combination with an alternative coordinatization of the manifold of hypersurfaces, which circumvents the need for the introduction of a "phantom" reference manifold $Γ_\infty$ by, in its place, making use of a "phantom geometry" on $Γ_0$. The upshot is a clear insight into the structure of the linearization, simplified calculations, and simpler formulæ for the resulting linear operators, which are useful in applications.

Scattering of low lying states in the black hole atmosphere

Year: 2016
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate finite $α'$ effects in string theory on a black hole background. By explicitly computing tree level scattering amplitudes, we confirm a duality between seemingly different states recently conjectured by Giveon, Itzhaki, and Kutasov in [arXiv:1603.05822]. We verify that the relevant 3-point functions factorize in such a way that the duality between oscillator and winding states becomes manifest. This leads to determine the precise normalization of the dual vertex operators, and confirms at the level of the interacting theory the identification of states suggested by the analysis of the spectrum. This result implies a duality between two seemingly distinct mechanisms driving the violation of the string winding number in the black hole atmosphere.

description: Unconventional superconductors are of high interest due to their rich physics, a topical example being topological edge-states associated with $p$-wave superconductivity. A practical obstacle in studying such systems is the very low critical temperature $T_\text{c}$ that is required to realize a $p$-wave superconducting phase in a material. We predict that the $T_\text{c}$ of an intrinsic $p$-wave superconductor can be significantly enhanced by coupling it via an atomically thin ferromagnetic layer (F) to a conventional $s$-wave or a $d$-wave superconductor with a higher critical temperature. We show that this $T_\text{c}$-boost is tunable via the direction of the magnetization in F. Moreover, we show that the enhancement in $T_\text{c}$ can also be achieved using the Zeeman-effect of an external magnetic field. Our findings provide a way to increase $T_\text{c}$ in $p$-wave superconductors in a controllable way and make the exotic physics associated with such materials more easily accessible experimentally.

We provide conditions on the group and the semiglobal field under which the local-global principle holds, and we compute the obstruction to the local-global principle in certain classes of examples. Using our description of the obstruction, we give the first example of a semisimple simply connected group over a semi-global field where the local-global principle fails. Our methods include patching and R-equivalence.

description: The orbital angular momentum is a core ingredient of orbital magnetism, spin Hall effect, giant Rashba spin splitting, orbital Edelstein effect, and spin-orbit torque. However, its experimental detection is tricky. In particular, direct detection of the orbital Hall effect remains elusive despite its importance for electrical control of magnetic nanodevices. Here we report the direct observation of the orbital Hall effect in a light metal Ti. The Kerr rotation by the accumulated orbital magnetic moment is measured at Ti surfaces, whose result agrees with theoretical calculations semiquantitatively and is supported by the orbital torque measurement in Ti-based magnetic heterostructures. The results confirm the electron orbital angular momentum as an essential dynamic degree of freedom, which may provide a novel mechanism for the electric control of magnetism. The results may also deepen the understanding of spin, valley, phonon, and magnon dynamics coupled with orbital dynamics.

description: Molecular adsorbates on metal surfaces exchange energy with substrate phonons and low-lying electron-hole pair excitations. In the limit of weak coupling, electron-hole pair excitations can be seen as exerting frictional forces on adsorbates that enhance energy transfer and facilitate vibrational relaxation or hot-electron mediated chemistry. We have recently reported on the relevance of tensorial properties of electronic friction [Phys. Rev. Lett. 116, 217601 (2016)] in dynamics at surfaces. Here we present the underlying implementation of tensorial electronic friction based on Kohn-Sham Density Functional Theory for condensed phase and cluster systems. Using local atomic-orbital basis sets, we calculate nonadiabatic coupling matrix elements and evaluate the full electronic friction tensor in the classical limit. Our approach is numerically stable and robust as shown by a detailed convergence analysis. We furthermore benchmark the accuracy of our approach by calculation of vibrational relaxation rates and lifetimes for a number of diatomic molecules at metal surfaces. We find friction-induced mode-coupling between neighboring CO adsorbates on Cu(100) in a c(2x2) overlayer to be important to understand experimental findings.

Testing natural selection of the adenovirus receptor gene CXADR in Anolis lizards
Creators: name: Ebenezer, Andrew Theophilus
Publisher: name: No Publisher Supplied
Year: 2022

description: CXADR is expressed in a broad range of hosts and is explicitly exploited by Adenoviruses (AdVs) which undergo host transfers and hypothesized to coevolve with its host. AdVs infect Anoles, a highly diverse genus of reptiles with several strains and recorded cases of mortality and morbidity due to AdV infection. While AdV disease dynamics are studied diligently, evolutionary analyses of CXADR are lacking. I therefore chose to investigate the impacts that Adenovirus has influencing selection on CXADR in anoles, by performing evolutionary genomic analysis on DNA and RNA sequences collected via experimental and computational approaches. Using the data to (i) infer the evolutionary relationships of CXADR among anole species, (ii) test the prediction that CXADR in anoles will reveal a diverse pattern of positive natural selection due to selective pressure driven by Adenovirus, and (iii) reconstruct protein structures of CXADR to examine protein conservation in vertebrates. I found evidence for a mixture of natural selection in CXADR in anoles at varying evolutionary depths. Furthermore, I predicted the structure of CXADR is deeply conserved which suggests my observation of positive selection is remarkable given the relatively slow evolution of this gene.

description: Brownian coating thermal noise in detector test masses is limiting the sensitivity of current gravitational-wave detectors on Earth. Therefore, accurate numerical models can inform the ongoing effort to minimize Brownian coating thermal noise in current and future gravitational-wave detectors. Such numerical models typically require significant computational resources and time, and often involve closed-source commercial codes. In contrast, open-source codes give complete visibility and control of the simulated physics, enable direct assessment of the numerical accuracy, and support the reproducibility of results. In this article, we use the open-source SpECTRE numerical relativity code and adopt a novel discontinuous Galerkin numerical method to model Brownian coating thermal noise. We demonstrate that SpECTRE achieves significantly higher accuracy than a previous approach at a fraction of the computational cost. Furthermore, we numerically model Brownian coating thermal noise in multiple sub-wavelength crystalline coating layers for the first time. Our new numerical method has the potential to enable fast exploration of realistic mirror configurations, and hence to guide the search for optimal mirror geometries, beam shapes and coating materials for gravitational-wave detectors.

description: INTRODUCTION: Poor personal hygiene creates a serious public health threat to school children. Due to poor personal hygiene practices, the increasing burden of communicable diseases among school children remains a concern on the public health agenda in developing countries. OBJECTIVE: To assess the factors associated with personal hygiene practice among school children in Boda primary school around Ginci twon ,west Shoa, Oromia, Ethiopia, 2016. METHODS: A school based cross-sectional study design supported by qualitative approach was conducted among school children in Boda primary school children from February to March 2016 among 354 school children through stratified sampling method to select the study subject. Data was collected using structured and pre-tested questionnaire face to face interview. Data entry, cleaning, editing and analysis were done using Epi info version 3.5 and SPSS statistical software version 21.0. To identify independent variables which had statistically significant association, bivariate and multivariate analysis using logistic regression was employed. For qualitative method: Data was collected by principal investigator using in depth interview among school teacher and school director (selected by purposive sampling method) and data was analysed using thematic analysis. RESULTS: About 59 % school children had good knowledge about personal hygiene and about 54.2% had poor personal hygiene practice. Factors significantly associated with personal hygiene practice at p value <0.05 were grade level(COR= 2.09 (95% CI(1.34,3.33), age(COR=2.53 (95% CI(1.63, 3.93)), family occupation(COR =2.07(95% CI (1.12,3.84)) , maternal education status (AOR =2.74(95% CI(1.47,5.13)), being member of hygiene and sanitation club(COR=1.83 (95 % CI(1.01, 3.35)), availabilities of hygiene facilities (AOR=2.44(95% CI(1.35,4.42)) and knowledge about personal hygiene (AOR=2.76(95%(CI(1.48,5.17)). CONCLUSION AND RECCOMENDATION: About 59 % school children had good knowledge and 54.2% had poor personal hygiene practice. Grade level, age, family occupation, family education status, being member of hygiene and sanitation club, availabilities of hygiene facilities and knowledge about personal hygiene were significantly associated with personal hygiene practice. Therefore, health education and promotion on personal hygiene is recommended as intervention in the rural primary schools. Key words: Factors, personal hygiene practice, Boda primary school, Ginci town.

description: An increasing number of research topics and applications ask for a precise measurement of the size distribution of small bubbles in a liquid - and hence for reliable and automated image analysis. However, due to the strong mismatch between the refractive index of a liquid and a gas, bubbles deform strongly the path of light rays, rendering automated bubble size analysis a challenging task. We show here how this challenge can be met using the fact that bubbles act like inverted, spherical lenses with a curvature which is the inverse of the bubble radius. The imaging properties of each bubble can then be used to accurately determine the radius of the bubble upon imaging an object which can be filtered easily by a computer. When bubbles are large enough to be deformed under the influence of gravity, it is more appropriate to measure their size after squeezing them between two narrowly spaced glass plates. We therefore show here, how the analysis can be extended to this case; and how both approaches can be combined to measure the size distributions of strongly polydisperse foams containing simultaneously small (several 10s of micrometres) and large bubbles (several 100s of micrometres).
Enhanced superconductivity and various edge modes in modulated $t$-$J$ chains

description: We numerically investigate the ground state of the extended $t$-$J$ Hamiltonian with periodic local modulations in one dimension by using the density-matrix renormalization group method. Examining charge and spin excitation gaps, as well as the pair binding energy, with extrapolated results to the thermodynamic limit, we obtain a rich ground-state phase diagram consisting of the metallic state, the superconducting state, the phase separation, and insulating states at commensurate fillings. Compared to the homogeneous 1D $t$-$J$ model, the superconductivity is greatly enhanced and stabilized by the flat-band structure. This superconducting state in quasi-periodic chains shares similar properties with ladder systems: significant negative pair binding energy occurs, and the singlet pairing correlation function dominates with the algebraic decay while the single-particle Green's function and spin correlation function decay exponentially. On the other hand, quasi-periodicity leads to nontrivial topological nature in insulating states, characterized by different integer Chern numbers at different fillings. Due to the interplay among the topology, the interaction, and the 1D confinement, gapless edge modes show strong spin-charge separation and in different regions can relate to different collective modes, which are the charge of a single fermion, the magnon, and the singlet-pair. We also find two interaction driven topological transitions: i) at particle filling $ρ=1/2$, the low-energy edge excitations change from the magnon to singlet-pair, accompanied with pair formation in bulk; and ii) at $ρ=3/4$, while the gapless edge mode remains the charge of a single fermion, there is a gap-closing point and a $π$-phase shift in the quasi-particle spectrum.

description: We study the Felderhof free-fermion six-vertex model, whose wavefunction recently turned out to possess rich combinatorial structure of the Schur polynomials. We investigate the dual version of the wavefunction in this paper, which seems to be a harder object to analyze. We evaluate the dual wavefunction in two ways. First, we give the exact correspondence between the dual wavefunction and the Schur polynomials, for which two proofs are given. Next, we make a microscopic analysis and express the dual wavefunction in terms of strict Gelfand-Tsetlin pattern. As a consequence of these two ways of evaluation of the dual wavefunction, we obtain a dual version of the Tokuyama combinatorial formula for the Schur polynomials. We also give a generalization of the correspondence between the dual wavefunction of the Felderhof model and the factorial Schur polynomials.

description: Using microscopy to investigate stomatal behaviour is common in plant physiology research. Manual inspection and measurement of stomatal pore features is low throughput, relies upon expert knowledge to record stomatal features accurately, requires significant researcher time and investment, and can represent a significant bottleneck to research pipelines.To alleviate this, we introduce StomaAI (SAI): a reliable, user-friendly and adaptable tool for stomatal pore and density measurements via the application of deep computer vision, which has been initially calibrated and deployed for the model plant Arabidopsis (dicot) and the crop plant barley (monocot grass).SAI is capable of producing measurements consistent with human experts and successfully reproduced conclusions of published datasets.SAI boosts the number of images that can be evaluated in a fraction of the time, so can obtain a more accurate representation of stomatal traits than is routine through manual measurement. An online demonstration of SAI is hosted at https://sai.aiml.team, and the full local application is publicly available for free on GitHub through https://github.com/xdynames/sai-app.

Creators: name: Dida, Golo
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2013

description: The objective of this study is to examine entrepreneurial intention and determinants. Specifically, the study tried to examine the impact of Gender, Family background, Social norm, Entrepreneurship education, perceived government policy and Perceived access to finance to entrepreneurial intention of university students in Addis Ababa. The quantitative approach was employed as research design. Simple Random sampling technique was used to draw sample from population. Data was collected though questionnaire and collected data was analysised through descriptive statistics, independent t-test and correlation analysis. The significant difference in entrepreneurial intention was found between male and female students, and also between students from business family background and non business family background. The significant difference in entrepreneurial intention was not found between students those had took entrepreneurship education and those had not taken entrepreneurship education. The result indicated that there is significant positive relationship exist between Social norm and entrepreneurial intention. The result indicated that there is not significant positive relationship exist between perceived access to finance and entrepreneurial intention and also the result indicated that there is not significant positive relationship exist between perceived government policy and entrepreneurial intention. There was no study conducted in Ethiopia relating to entrepreneurial intention and its determinants. In order to fill this gap, a sample of university students in Addis Ababa was investigated. Key words: Entrepreneurial intention, Determinants, university and student

description: Unsupervised graph representation learning has recently gained interest in several application domains such as neuroscience, where modeling the diverse morphology of cell types in the brain is one of the key challenges. It is currently unknown how many excitatory cortical cell types exist and what their defining morphological features are. Here we present GraphDINO, a purely data-driven approach to learn low-dimensional representations of 3D neuronal morphologies from unlabeled large-scale datasets. GraphDINO is a novel transformer-based representation learning method for spatially-embedded graphs. To enable self-supervised learning on transformers, we (1) developed data augmentation strategies for spatially-embedded graphs, (2) adapted the positional encoding and (3) introduced a novel attention mechanism, AC-Attention, which combines attention-based global interaction between nodes and classic graph convolutional processing. We show, in two different species and across multiple brain areas, that this method yields morphological cell type clusterings that are on par with manual feature-based classification by experts, but without using prior knowledge about the structural features of neurons. Moreover, it outperforms previous approaches on quantitative benchmarks predicting expert labels. Our method could potentially enable data-driven discovery of novel morphological features and cell types in large-scale datasets. It is applicable beyond neuroscience in settings where samples in a dataset are graphs and graph-level embeddings are desired.

description: We present high-resolution (0.16$"$) 870um Atacama Large Millimeter/submillimeter Array (ALMA) imaging of 16 luminous (L_IR ~ 4 x 10^12 L_sun) submillimeter galaxies (SMGs) from the ALESS survey of the Extended Chandra Deep Field South. This dust imaging traces the dust-obscured star formation in these z~2.5 galaxies on ~1.3 kpc scales. The emission has a median effective radius of $R_e=0.24" \pm 0.02"$, corresponding to a typical physical size of $R_{e}=1.8\pm$0.2 kpc. We derive a median Sérsic index of $n=0.9\pm0.2$, implying that the dust emission is remarkably disk-like at the current resolution and sensitivity. We use different weighting schemes with the visibilities to search for clumps on 0.12$"$ (~1.0 kpc) scales, but we find no significant evidence for clumping in the majority of cases. Indeed, we demonstrate using simulations that the observed morphologies are generally consistent with smooth exponential disks, suggesting that caution should be exercised when identifying candidate clumps in even moderate S/N interferometric data. We compare our maps to comparable-resolution HST H$_{160}$-band images, finding that the stellar morphologies appear significantly more extended and disturbed, and suggesting that major mergers may be responsible for driving the formation of the compact dust disks we observe. The stark contrast between the obscured and unobscured morphologies may also have implications for SED fitting routines that assume the dust is co-located with the optical/near-IR continuum emission. Finally, we discuss the potential of the current bursts of star formation to transform the observed galaxy sizes and light profiles, showing that the $z\sim0$ descendants of these SMGs are expected to have stellar masses, effective radii, and gas surface densities consistent with the most compact massive (M_* ~ 1-2 x 10^11 M_sun) early-type galaxies observed locally.

Many-Body-Localization Transition : sensitivity to twisted boundary conditions

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: For disordered interacting quantum systems, the sensitivity of the spectrum to twisted boundary conditions depending on an infinitesimal angle $ϕ$ can be used to analyze the Many-Body-Localization Transition. The sensitivity of the energy levels $E_n(ϕ)$ is measured by the level curvature $K_n=E_n"(0)$, or more precisely by the Thouless dimensionless curvature $k_n=K_n/Δ_n$, where $Δ_n$ is the level spacing that decays exponentially with the size $L$ of the system. For instance $Δ_n \propto 2^{-L}$ in the middle of the spectrum of quantum spin chains of $L$ spins, while the Drude weight $D_n=L K_n$ studied recently by M. Filippone, P.W. Brouwer, J. Eisert and F. von Oppen [arxiv:1606.07291v1] involves a different rescaling. The sensitivity of the eigenstates $\vert ψ_n(ϕ) > $ is characterized by the susceptibility $χ_n=-F_n"(0)$ of the fidelity $F_n =\vert < ψ_n(0) \vert ψ_n(ϕ) >\vert $. Both observables are distributed with probability distributions displaying power-law tails $P_β(k) \simeq A_β \vert k \vert^{-(2+β)} $ and $Q(χ) \simeq B_β χ^{-\frac{3+β}{2}} $, where $β$ is the level repulsion index taking the values $β^{GOE}=1$ in the ergodic phase and $β^{loc}=0$ in the localized phase. The amplitudes $A_β$ and $B_β$ of these two heavy tails are given by some moments of the off-diagonal matrix element of the local current operator between two nearby energy levels, whose probability distribution has been proposed as a criterion for the Many-Body-Localization transition by M. Serbyn, Z. Papic and D.A. Abanin [Phys. Rev. X 5, 041047 (2015)].

description: "Ultra-low" Q value $β$ decays are referred to as such due to their low decay energies of less than $\sim$1 keV. Such a low energy decay is possible when the parent nucleus decays into an excited state in the daughter, with an energy close to that of the Q value. These decays are of interest as potential new candidates for neutrino mass determination experiments and as a testing ground for studies of atomic interference effects in the nuclear decay process. In this paper, we provide an updated evaluation of atomic mass data and nuclear energy level data to identify potential ultra-low Q value $β$ decay candidates. For many of these candidates, more precise and accurate atomic mass data is needed to determine if the Q value of the potential ultra-low decay branch is energetically allowed and in fact ultra-low. The precise atomic mass measurements can be achieved via Penning trap mass spectrometry.

description: Background; Recently Diabetes mellitus is becoming an important clinical and public health problem throughout the world. In Ethiopia although it is known that diabetes is becoming one of the emerging health issue, little is known about its prevention and the different ways of management in the general population. Specifically when we see type 1 diabetes mellitus (T1DM), which mostly affects children is now increasing rapidly. So in order to prevent and manage it properly we have to include all responsible bodies. Families who are supportive and knowledgeable can affect the outcome of the diabetes in a good way. This study has tried to assess the knowledge and associated factors that the care givers had. Objectives; The objective of this study is to assess the knowledge of type 1 diabetes mellitus and associated factors among care givers of children attending diabetic clinic in hospitals in Addis Ababa, Ethiopia, from March to June 2016. Methods; An institutional based quantitative cross sectional study was employed with the care givers of children with T1DM, in public hospitals, Addis Ababa, Ethiopia. The number of caregivers was 149. A structured interviewer administered questionnaire was used to collect information, and then the data was coded, entered and cleaned using the statistical software Epi data. Then the analysis was made with IBM Statistical Package for Social Sciences (SPSS) version 22.0 after exporting the prepared data. Logistic regression analysis was used to assess the relative effect of determinants. A P<0.05 was considered statistically significant in all tests of significance. Results; This study revealed that less than half of caregivers (45%) have good level of knowledge about type1 diabetes. And this study also found that there were highly statistical significant association between total knowledge and sex, level of education, residence, income and attending workshop about DM. Conclusion; This study found that majority of the caregivers is less knowledgeable about T1DM which would in turn affect the care they give to their child. This study also found that sex, education, income, residence and attending workshops, trainings about T1DM as factors significantly associated with level of knowledge of caregivers.

description: We consider a RG flow in a general su(2) coset model induced by the least relevant field. This is done using two different approaches. We first compute the mixing coefficients of certain fields in the UV and IR theories using a conformal perturbation theory. The necessary structure constants are computed. The same coefficients can be calculated using the RG domain wall construction of Gaiotto. We compute the corresponding one-point functions and show that the two approaches give the same result in the leading order.
