description: This dissertation examines the Strengths and Difficulties Questionnaire (SDQ) in German classrooms. In doing so, the factor structure of the SDQ was found sufficiently similar to established 5- and 3- factor models. In the three included articles, longitudinal changes in SDQ performance are examined, and the SDQ is connected to student performance (i.e., grades and competency) and the Perception of Inclusion Questionnaire (PIQ). This establishes not only a validation of the structure of the SDQ, but also external comparisons. Through development in the primary school level, problem scores on the SDQ were increased, while prosocial behavior decreased. This was in keeping with the bidirectional feedback model, indicating that such problems affect academic performance, which can then spawn additional problems, creating a feedback loop. Next, high social problems scores on the SDQ were linked to worse performance in math and German in secondary schools, thus establishing a connection between problems and academic achievement. Finally, a possible mechanism of this process was examined via the comparison to the PIQ, which demonstrated that children with internalizing and externalizing problems in inclusive classrooms feel less included and also self-report a lower level of academic self-concept.

description: An experiment was carried out to examine effect of gradual inclusion of Papua foxtail millet (Setaria italica sp) to substitute yellow corn on breast meat quality and blood profiles in broilers. Two hundred and fifty day old chicks were used and alloted to 25 experimental units of 10 chicks. Five different dietary treatments were set, namely (i) T0 = basal feed, (ii) T1 = basal feed of which 2.5 % of yellow corn was substituted by Papua foxtail millet, (iii) T2 = basal feed of which 5.0 % of yellow corn was substituted by Papua foxtail millet, (iv) T3 = basal feed of which 7.5 % of yellow corn was substituted by Papua foxtail millet, (v) T4 = basal feed of which 10.0 % of yellow corn was substituted by Papua foxtail millet. All dietary treatments were set as iso-protein and iso-energy. At the end of experiment 2 birds in each experimental unit was selected, 25 birds were slaughtered and breast meats were sampled. Blood samples were taken from another 25 birds. On the basis of meat quality, water content, water holding capacity, colour and tenderness were analyzed. While for blood profiles, the measured variables included concentrations of serum haemoglobin, erythrocite, glukose and triglyceride. The results showed that level of Papua foxtail millet (Setaria italica sp) did dose dependently improve (P>0.05) tenderness of broiler meat, on the other hand redness of broiler meat did significantly change (P<0.01) with tendency less redness colour appear when Papua foxtail millet added more than 5% in the diet. No changes in lightness and yellowness of breast meat were reported. All blood profiles measurements of broiler showed that no physiologycal changes due to inclusion of Papua foxtail millet to replace corn. Based on this research, it is concluded that Papua foxtail millet might be used 10% in the diet to improve tenderness and redness of broiler meat.

description: A path integral (Lagrangian formalism) is used to derive the effective equations of motion of the anomalous Hall effect with Berry's phase on the basis of the adiabatic condition $|E_{n\pm1}-E_{n}|\gg 2π\hbar/T$, where $T$ is the typical time scale of the slower system and $E_{n}$ is the energy level of the fast system. In the conventional definition of the adiabatic condition with $T\rightarrow {\rm large}$ and fixed energy eigenvalues, no commutation relations are defined for slower variables by the Bjorken-Johnson-Low prescription except for the starting canonical commutators. On the other hand, in a singular limit $|E_{n\pm1}-E_{n}|\rightarrow \infty$ with specific $E_{n}$ kept fixed for which any motions of the slower variables $X_{k}$ can be treated to be adiabatic, the non-canonical dynamical system with deformed commutators and the Nernst effect appear. In the Born-Oppenheimer approximation based on the canonical commutation relations, the equations of motion of the anomalous Hall effect is obtained if one uses an auxiliary variable $X_{k}^{(n)}=X_{k}+{\cal A}^{(n)}_{k}$ with Berry's connection ${\cal A}^{(n)}_{k}$ in the absence of the electromagnetic vector potential $eA_{k}(X)$ and thus without the Nernst effect. It is shown that the gauge symmetries associated with Berry's connection and the electromagnetic vector potential $eA_{k}(X)$ are incompatible in the canonical Hamiltonian formalism. The appearance of the non-canonical dynamical system with the Nernst effect is a consequence of the deformation of the quantum principle to incorporate the two incompatible gauge symmetries.

description: In Deutschland erwerben aktuell knapp 20% Grundschülerinnen und Grundschüler unzureichende Lesekompetenzen, sodass das Lernen in der Sekundarstufe beeinträchtigt wird. Forschende fordern für Schülerinnen und Schüler mit einem Risiko zur Ausbildung von Leseschwierigkeiten eine präventive Leseförderung, die an individuellen Lernbedürfnissen ansetzt. Ein möglicher Ansatz ist die Lernverlaufsdiagnostik (LVD). Allerdings stehen für den deutschen Grundschulleseunterricht reliable Lernverlaufstests mit einem engen Bezug zu Lesemodellen aus. Die vorliegende Dissertation geht anhand von fünf Studien der Entwicklung, Evaluation und Implementation von LVD nach: Studie 1 systematisiert publizierte Lernverlaufstests zur Messung der Leseflüssigkeit. Aktuell besteht ein Mangel an digitaler LVD, die in der Testkonstruktion einen engen Bezug zu Lesemodellen herstellen. Diesem Mangel wird in Studie 2 und Studie 3 nachgegangen. Es werden die theoriegeleitete Testkonstruktion von jeweils einem neuen Lernverlaufstests (Leseflüssigkeits- und Leseverständnistest) vorgestellt und die psychometrischen Gütekriterien, die Eindimensionalität, die Änderungssensibilität und die Testfairness geprüft. Beide Tests erfassen die Leseleistungen von unterschiedlichen Gruppen von Schülerinnen und Schülern reliabel und änderungssensibel über mehrere Messzeitpunkte in unterschiedlichem zeitlichem Abstand. Studie 4 untersucht mögliche Lernverläufe in Abhängigkeit vom Leseausgangsniveau sowie den Einsatz der neuen Lernverlaufstests in der dritten und vierten Jahrgangsstufe mit vier Messzeitpunkten im Längsschnitt über ein Schuljahr. Die erprobten Instrumente sind jahrgangsübergreifend Lesenden mit geringen und mittleren Leseleistungen einsetzbar. Studie 5 erörtert Bedingungen für eine erfolgreiche Implementation der neuen Tests in deutschen Grundschulen. Insbesondere eine Unterstützung bei der technischen Anwendung und bei der Grapheninterpretation werden benötigt. Insgesamt zeigt die Dissertation, dass die neu entwickelte theoriegeleitete Testkonstruktion den Ansprüchen der inklusiven Grundschule standhält. Durch die Tests kann der kindliche Lernverlauf gemessen und Förderimplikationen abgeleitet werden. Die Tests sind digital in der Onlineplattform www.levumi.de sowie als Papierversion mit unterstützenden Materialien veröffentlicht. Zukünftig muss der Ansatz der LVD in der Aus- und Weiterbildung von Lehrkräften weiter publik gemacht werden. Außerdem werden notwendige systemische Rahmenbedingungen für eine flächendeckende Implementation von Lernverlaufstests diskutiert.

description: We consider the compactification of a Yang-Mills theory on a three-dimensional nilmanifold. The compactification generates a Yang-Mills theory in four space-time dimensions, coupled to a specific scalar sector. The compactification geometry gives rise to masses for the zero-modes, proportional to the twist parameter of the nilmanifold. We study the simple example of an SU (3) model broken by a non-trivial vacuum of the scalar potential which generates three mass scales, two being at tree level, and the third one at loop level. We point out the relevance of general twisted geometries for model building and in particular for gauge-Higgs type models, as the twist generates tree-level mass hierarchies useful for grand unification and for the Higgs sector in electroweak symmetry breaking.

description: We report the serendipitous discovery of an overdensity of CO emitters in an X-ray-identified cluster (Log$_{10}$M$_{\rm halo}/M_{\odot}\sim13.6$ at z=1.3188) using ALMA. We present spectroscopic confirmation of 6 new cluster members exhibiting CO(2-1) emission, adding to 2 existing optical/IR spectroscopic members undetected in CO. This is the lowest mass cluster to date at z>1 with molecular gas measurements, bridging the observational gap between galaxies in the more extreme, well-studied clusters (Log$_{10}$~M$_{\rm halo}/M_{\odot}\gtrsim14$) and those in group or field environments at cosmic noon. The CO sources are concentrated on the sky (within ~1-arcmin diameter) and phase space analysis indicates the gas resides in galaxies already within the cluster environment. We find that CO sources sit in similar phase space as CO-rich galaxies in more massive clusters at similar redshifts (have similar accretion histories) while maintaining field-like molecular gas reservoirs, compared to scaling relations. This work presents the deepest CO survey to date in a galaxy cluster at z>1, uncovering gas reservoirs down to M$_{\rm H_{2}}>1.6\times10^{10}$M$_{\odot}$ (5$σ$ at 50% primary beam). Our deep limits rule out the presence of gas content in excess of the field scaling relations; however, combined with literature CO detections, cluster gas fractions in general appear systematically high, on the upper envelope or above the field. This study is the first demonstration that low mass clusters at z~1-2 can host overdensities of CO emitters with surviving gas reservoirs, in line with the prediction that quenching is delayed after first infall while galaxies consume the gas bound to the disk.

description: Speed-of-sound and attenuation of ultrasound waves vary in the tissues. There exist methods in the literature that allow for spatially reconstructing the distribution of group speed-of-sound (SoS) and frequency-dependent ultrasound attenuation (UA) using reflections from an acoustic mirror positioned at a known distance from the transducer. These methods utilize a conventional ultrasound transducer operating in pulse-echo mode and a calibration protocol with measurements in water. In this study, we introduce a novel method for reconstructing local SoS and UA maps as a function of acoustic frequency through Fourier-domain analysis and by fitting linear and power-law dependency models in closed form. Frequency-dependent SoS and UA together characterize the tissue comprehensively in spectral domain within the utilized transducer bandwidth. In simulations, our proposed methods are shown to yield low reconstruction error: 0.01 dB/cm.MHz^y for attenuation coefficient and 0.05 for the frequency exponent. For tissue-mimicking phantoms and ex-vivo bovine muscle samples, a high reconstruction contrast was achieved. Attenuation exponents in a gelatin-cellulose mixture and an ex-vivo bovine muscle sample were found to be, respectively, 1.3 and 0.6 on average. Linear dispersion of SoS in a gelatin-cellulose mixture and an ex-vivo bovine muscle sample were found to be, respectively, 1.3 and 4.0 m/s.MHz on average. These findings were reproducible when the inclusion and substrate materials were exchanged. Bulk loss modulus in the bovine muscle sample was computed to be approximately 4 times the bulk loss modulus in the gelatin-cellulose mixture. Such frequency-dependent characteristics of SoS and UA, and bulk loss modulus may therefore differentiate tissues as potential diagnostic biomarkers.

description: Online technical forums (e.g., StackOverflow) are popular platforms for developers to discuss technical problems such as how to use specific Application Programming Interface (API), how to solve the programming tasks, or how to fix bugs in their codes. These discussions can often provide auxiliary knowledge of how to use the software that is not covered by the official documents. The automatic extraction of such knowledge will support a set of downstream tasks like API searching or indexing. However, unlike official documentation written by experts, discussions in open forums are made by regular developers who write in short and informal texts, including spelling errors or abbreviations. There are three major challenges for the accurate APIs recognition and linking mentioned APIs from unstructured natural language documents to an entry in the API repository: (1) distinguishing API mentions from common words; (2) identifying API mentions without a fully qualified name; and (3) disambiguating API mentions with similar method names but in a different library. In this paper, to tackle these challenges, we propose an ARCLIN tool, which can effectively distinguish and link APIs without using human annotations. Specifically, we first design an API recognizer to automatically extract API mentions from natural language sentences by a Conditional Random Field (CRF) on the top of a Bi-directional Long Short-Term Memory (Bi-LSTM) module, then we apply a context-aware scoring mechanism to compute the mention-entry similarity for each entry in an API repository. Compared to previous approaches with heuristic rules, our proposed tool without manual inspection outperforms by 8% in a high-quality dataset Py-mention, which contains 558 mentions and 2,830 sentences from five popular Python libraries.

description: The paper tests the validity of the critique of the fiscal theory of the price level. A stochastic general equilibrium model with continuous time is constructed. An active fiscal policy and a passive monetary policy have been set. Monetary policy manages the interest rate through the Taylor rule. The stochastic default factor in the special form is introduced. A complete definite system of equations is obtained for the detection of equilibrium. It is asserted that the peculiarities of the approach to modeling are of critical importance for verifying the presence of certain hypotheses and formulating conclusions. The results of this work are in support of the fiscal theory of the price level.

description: The presented study deals with the experimental characterization of damping materials for acoustic simulations with respect to the stiffness and damping in dependence of the excitation frequency, i.e. frequency-dependent elasticity modulus. The test rigs under consideration utilize a shaker, acceleration sensors and a laser Doppler vibrometer (LDV) to measure oscillating behaviour at frequencies ranging from 20 to 2000 Hz. Suitable mounting properties of the test rigs are examined experimentallyand by finite element analysis. The applicability of the gained results for acoustic simulations is investigated with results from a window test setup.

description: In this paper, we investigate the impact of the phase conversion speed on the properties of hybrid stars with sequential sharp QCD phase transitions. We consider that these hybrid stars possess an inner (outer) core of CFL (2SC) quark matter surrounded by hadronic matter. Assuming that the phase conversions can be slow or rapid, we analyze the dynamical stability of these objects. In particular, we present our predictions for the mass-radius profile and the fundamental eigenfrequencies of hybrid stars with sequential QCD first order phase transitions. Our results demonstrate that the usual stability criteria i.e. $\partial M/ \partial P_0 \geq 0$, is sufficient only if both conversions are rapid. Moreover, we show that if any of the interfaces has a slow conversion speed, the fundamental eigenfrequencies are significantly modified.

description: Recent advancements in quantum technologies and advanced detection experiments have underscored the pressing need for the detection of exceedingly weak signals within the microwave frequency spectrum. Addressing this challenge, the Josephson Traveling Wave Parametric Amplifier (JTWPA) has been proposed as a cryogenic front-end amplifier capable of approaching the quantum noise limit while providing a relevant bandwidth. This research is centered on a comprehensive numerical investigation of the JTWPA, without resorting to simplifications regarding the nonlinearity of the essential components. Specifically, this study focuses on a thorough examination of the system, characterized by coupled nonlinear differential equations representing all components of the device. Proper input and output signals at the device's boundaries are considered. The analysis of the output signals undergoing the parametric amplification process involves a detailed exploration of phase-space dynamics and Fourier spectral analysis of the output voltage. This study is conducted while considering the parameters ruling the response of the device under pump and signal excitations. In addition to the expected signal amplification, the findings reveal that the nonlinear nature of the system can give rise to unforeseen phenomena, depending on the system's operational conditions, which include: the generation of pump tone harmonics, modulation of the signal gain, and incommensurate frequency generation-effects that are not easily accommodated by simplistic linearized approaches

description: The destruction of the event horizon of a nonsingular black hole, which is not prevented by the weak cosmic censorship conjecture, might provide us the possibility to access quantum regime of gravity inside black hole. We investigate the possibility of overspinning a nonsingular rotating quantum-corrected black hole by a test particle and a scalar field in this paper, and analyse the effect of the quantum parameter on the destruction of the event horizon. For the test particle injection, both extremal and near-extremal black holes cannot be overspun due to the existence of the quantum parameter. And the larger the quantum parameter the harder the black hole to be overspun. It seems that the quantum parameter acts as a protector to prevent the black hole to be destroyed. However, for the test scalar field scattering, both extremal and near-extremal black holes can be destroyed. Due to the loop quantum gravity correction, the angular velocity of the extremal black hole shifts from that of the extremal Kerr black hole. This provides a small range of wave modes to destroy the event horizon of the quantum-corrected black hole.

description: Classical T Tauri stars are surrounded by a circumstellar disk from which they are accreting material. This process is essential in the formation of Sun-like stars. Although often described with simple and static models, the accretion process is inherently time variable. Our aim is to examine the accretion process of the low-mass young stellar object CR Cha on a wide range of timescales from minutes to a decade by analyzing both photometric and spectroscopic observations from 2006, 2018, and 2019. We carried out period analysis on the light curves of CR Cha from the TESS mission and the ASAS-SN and the ASAS-3 databases. We studied the color variations of the system using $I,J,H,K$-band photometry obtained contemporaneously with the TESS observing window. We analyzed the amplitude, timescale, and the morphology of the accretion tracers found in a series of high-resolution spectra obtained in 2006 with the AAT/UCLES, in 2018 with the HARPS, and in 2019 with the ESPRESSO and the FEROS spectrographs. All photometric data reveal periodic variations compatible with a 2.327 days rotational period, which is stable in the system over decades. Moreover, the ASAS-SN and ASAS-3 data hint at a long-term brightening by 0.2 mag, between 2001 and 2008, and of slightly less than 0.1 mag in the 2015 - 2018 period. The near-infrared color variations can be explained by either changing accretion rate or changes in the inner disk structure. Our results show that the amplitude of the variations in the H$α$ emission increases on timescales from hours to days/weeks, after which it stays similar even when looking at decadal timescales. On the other hand, we found significant morphological variations on yearly/decadal timescales, indicating that the different physical mechanisms responsible for the line profile changes, such as accretion or wind, are present to varying degrees at different times.

description: On the basis of contribution of central institution impact on economic development and efficiency, the report scrutinizes the development of Albania. The report may emphasize on the role of bank ‘as central institution’ in the development of an economy. Efficiency of the financial institution in the small economy of a country has vital part of the Albanian economy. Financial crises have also left effects on Albanian economy, from which one of the most important issue faced is, instability of financial market.

description: The gravitational-wave events GW170817 and GW190425 have led to a number of important insights on the equation of state of dense matter and the properties of neutron stars, such as their radii and the maximum mass. Some of these conclusions have been drawn on the basis of numerical-relativity simulations of binary neutron-star mergers with vanishing initial spins. While this may be a reasonable assumption in equal-mass systems, it may be violated in the presence of large mass asymmetries accompanied by the presence of high spins. To quantify the impact of high spins on multi-messenger gravitational-wave events, we have carried out a series of high-mass binary neutron-star mergers with a highly spinning primary star and large mass asymmetries that have been modelled self-consistently using two temperature-dependent equations of state. We show that, when compared with equal-mass, irrotational binaries, these systems can lead to significant differences in the remnant lifetime, in the dynamical ejecta, in the remnant disc masses, in the secular ejecta, and on the bulk kilonova properties. These differences could be exploited to remove the degeneracy between low- and high-spin priors in the detection of gravitational waves from binary neutron-star mergers.

description: All stars produce explosive surface events such as flares and coronal mass ejections. These events are driven by the release of energy stored in coronal magnetic fields, generated by the stellar dynamo. However, it remains unclear if the energy deposition in the magnetic fields is driven by direct or alternating currents. Recently, we presented observational measurements of the flare intensity distributions for a sample of $\sim10^5$ stars across the main sequence observed by $\textit{TESS}$, all of which exhibited power-law distributions similar to those observed in the Sun, albeit with varying slopes. Here we investigate the mechanisms required to produce such a distribution of flaring events via direct current energy deposition, in which coronal magnetic fields braid, reconnect, and produce flares. We adopt a topological model for this process which produces a power-law distribution of energetic flaring events. We expand this model to include the Coriolis effect, which we demonstrate produces a shallower distribution of flare energies in stars that rotate more rapidly (corresponding to a weaker decline in occurrence rates toward increasing flare energies). We present tentative evidence for the predicted rotation-power-law index correlation in the observations. We advocate for future observations of stellar flares that would improve our measurements of the power-law exponents, and yield key insights into the underlying dynamo mechanisms that underpin the self-similar flare intensity distributions.

description: In part one the heredity of myopia,night-blindness and retinitis pigmentosa in association with other defects is discussed. This serves as an introduction to the second part which is concerned with search for genetic linkage relationships in families inheriting both haemophilia and colour-blindness. In the third part three large pedigrees of blue sclerotics, brittle bones and deafness are described. In the largest of these colour-blind individuals were found. This pedigree was examined in detail for blood-group and taste factors in an attempt to establish linkage relationships. The last section is based upon the investigation of five hundred consecutive patients examined primarily for errors of refraction in whom the condition of the ear lobes and iris colour was recorded. A short analysis of this material is made and the section concludes with a pedigree in which all these normal factors were investigated. The thesis is concluded with a note upon the problems discussed and the need for further work on these lines.

description: The legislation has become a part of every organization to maintain just ways of conducting businesses. In this context, the institutional strength perceptions are studied that how they affect the law obedience in Albania. The institutional strength perception is studied as independent variable whilst the dependent variable is law obedience. The research project is focused on finding conclusions on how the law obedience gets affected by the institutional strength perception (Burkus, 2012). This research will help organizations to find out the ways to improve their institutional strength which will in turn enhance the law obedience. The study revolves around law obedience because it is essential for the survival of any institution to follow the official frame of rules issued by astate or legislative authorities. It will also assist organizations in earning high performance by implementing law practices in their workplace. Further to it, it will act as a baseline for future researchers to take informative knowledge from this particular study in order to carry out the research in further parts which are still unknown(Givens, 2011). On the whole, this research will help to extract fruitful findings which will benefit both organizations as well as future researchers. Analyzing this relationship will surely help to extract some useful conclusions that will provide companies to enhance the efficiency of their performance. Furthermore, the findings of this research will be applicable in extracting the same relationship in the same sector in different regions of the world.
Directional Variations of Cosmological Parameters from the Planck CMB Data

description: Recent observations suggest that there are violations of the isotropy of the universe at large scales, an important part of the cosmological principle. In this paper, we use the Cosmic Microwave Background (CMB) data to search for spatial variations of the cosmological parameters in the $Λ\mathrm{CDM}$ model. We fit the Planck temperature angular power spectrum $\mathcal{C}^{TT}_\ell$ for 48 different half-skies, centering on 48 different directions, to search for directional dependences of the standard cosmological parameters. There are $3(2)σ$-level directional variations in $Ω_bh^2$, $Ω_ch^2$, $n_s$, $100θ_\mathrm{MC}$, and $H_0$ $(τ$ and $\ln(10^{10}A_s))$. Furthermore, the directional distributions of the parameters follow a dipole form to good approximation. The Bayes factor between the isotropic and anisotropic hypotheses is $0.0041$, strongly disfavouring the former. The best-fit dipole axes for $Ω_bh^2$, $Ω_ch^2$, $n_s$, $100θ_\mathrm{MC}$, and $A_s e^{-2τ}$ all generally align with the mean direction of $\boldsymbol{V} \equiv (b = -5.6^{+17.0{\circ}}_{-17.4}, l = 48.8^{+14.3{\circ}}_{-14.4})$, which is roughly perpendicular to the dipole of the variation in fine structure constant, and is about $45^{\circ}$ to the directions of the CMB kinematic dipole, CMB parity asymmetry, and polarization of QSOs. Our results suggest either significant violation of the cosmological principle, or previously unknown systematic errors in the standard CMB analysis.

description: Objective: To assess the gingival health status among preclinical and clinical Yemeni dental students. Materials and Methods: This cross-sectional study was conducted on preclinical and clinical students at Thamar University. The self-reported oral health behavior of dental students with their actual gingival status was evaluated. One hundred and ninety five volunteers (115 male and 80 females with mean age (21.71+1.72) who participated in this study completed the self-reported questionnaire. Subsequently a clinical examination for their gingival conditions was assessed. The clinical examination for the participants comprised plaque index, gingival index, gingival bleeding index, and calculus index. Results: The findings of this study showed that, the gingival health status was poor among dental students with no significant difference between preclinical and clinical students (P> 0.05). Females had better oral and gingival health status than males with significant differences (P< 0.05). The relationship between Khat chewing and smoking with gingival bleeding and calculus deposits was significant (P< 0.05). Conclusion: Preclinical and clinical dental students showed poor gingival health status. It is recommended that the educational programs and preventing dentistry curriculum should be modified in order to improve oral health care level among Yemeni dental students.
