description: We present a comprehensive analysis of the $γW$ interference radiative correction to the neutron $β$-decay matrix element. Within a dispersion relations approach, we compute the axial-vector part of the $γW$ box amplitude $\Box^{γW}_{A}$ in terms of the isoscalar part of the $F_3^{γW}$ interference structure function. Using the latest available phenomenology for $F_3^{γW}$ from the nucleon elastic, resonance, deep-inelastic, and Regge regions, we find the real part of the box correction to be $\Box^{γW}_A = 3.90(9) \times 10^{-3}$. This improved correction gives a theoretical estimate of the CKM matrix element $|V_{ud}|^2=0.94805(26)$, which represents a 4$σ$ violation of unitarity.

description: Today's world is witnessing an unparalleled rate of technological transformation. The emergence of non-fungible tokens (NFTs) has transformed how we handle digital assets and value. Despite their initial popularity, NFTs face declining adoption influenced not only by cryptocurrency volatility but also by trust dynamics within communities. From a social computing perspective, understanding these trust dynamics offers valuable insights for the development of both the NFT ecosystem and the broader digital economy. China presents a compelling context for examining these dynamics, offering a unique intersection of technological innovation and traditional cultural values. Through a content analysis of eight Chinese NFT-focused WeChat groups and 21 semi-structured interviews, we examine how socio-cultural factors influence trust formation and development. We found that trust in Chinese NFT communities is significantly molded by local cultural values. To be precise, Confucian virtues, such as benevolence, propriety, and integrity, play a crucial role in shaping these trust relationships. Our research identifies three critical trust dimensions in China's NFT market: (1) technological, (2) institutional, and (3) social. We examined the challenges in cultivating each dimension. Based on these insights, we developed tailored trust-building guidelines for Chinese NFT stakeholders. These guidelines address trust issues that factor into NFT's declining popularity and could offer valuable strategies for CSCW researchers, developers, and designers aiming to enhance trust in global NFT communities. Our research urges CSCW scholars to take into account the unique socio-cultural contexts when developing trust-enhancing strategies for digital innovations and online interactions.

description: Coumarins and benzoxazoles are fundamental building blocks of various compounds with pharmaceutical and biological activity. The purpose of this thesis is the metal-catalyzed synthesis of phenyl-substituted fused oxazolocoumarins and the study of the structure of the isolated compounds. We use three catalytic systems: (a) iron (III) chloride, FeCl3, (b) gold nanoparticles supported on titanium dioxide, Au/TiO2 and (c) silver nanoparticles supported on titanium dioxide, Ag/TiO2. The first chapter includes an introductory reference for the coumarins, the benzoxazoles and the three catalysts mentioned above. The second chapter includes the results and discussion, where the results of this thesis and the reactions, which were used, are presented, while the third section includes the experimental procedures and tables with experimental and spectroscopic data of the synthesized compounds. Finally the conclusions of this thesis are given. The structures of all compounds, four of which are new, were identified by combination of the chromatographic spectra of IR, MS and NMR (1H, 13C, HSQC and HMBC). Moreover, we propose potential reactions’ mechanisms that justify the structure of the isolated compounds.

description: We use the Mellin-Barnes representation in order to improve the theoretical estimate of mass corrections to the width of light pseudoscalar meson decay into a lepton pair, $P\to l^+l^-$ . The full resummation of the terms $\ln(m_l^2/Λ^2)(m_l^2/Λ^2)^n$ and $(m_l^2/Λ^2)^n$ to the decay amplitude is performed, where $m_l$ is the lepton mass and $Λ\approx m_ρ$ is the characteristic scale of the $P\toγ^*γ^*$ form factor. The total effect of mass corrections for the $e^+e^-$ channel is negligible and for the $μ^+μ^-$ channel its order is of a few per cent.

description: We introduce the notion of quasi-triangular Leibniz bialgebras, which can be constructed from solutions of the classical Leibniz Yang-Baxter equation (CLYBE) whose skew-symmetric parts are invariant. In addition to triangular Leibniz bialgebras, quasi-triangular Leibniz bialgebras contain factorizable Leibniz bialgebras as another subclass, which lead to a factorization of the underlying Leibniz algebras. Relative Rota-Baxter operators with weights on Leibniz algebras are used to characterize solutions of the CLYBE whose skew-symmetric parts are invariant. On skew-symmetric quadratic Leibniz algebras, such operators correspond to Rota-Baxter type operators. Consequently, we introduce the notion of skew-symmetric quadratic Rota-Baxter Leibniz algebras, such that they give rise to triangular Leibniz bialgebras in the case of weight $0$, while they are in one-to-one correspondence with factorizable Leibniz bialgebras in the case of nonzero weights.

description: This paper introduces a methodology for the development of routing algorithms that takes into consideration opportunistic networking. The proposal focus on the rationale behind the methodology, and highlights its most important stages and components. It also discusses the importance of two core elements in the process of protocol designing: the scenario selection, based on essential characteristics, and the choice of standard evaluation metrics. As of now, there has been no common methodology for developing new routing algorithms, and this has led to proposals difficult to compare, to evaluate, and lacking a rigorous objectivity ensuring fairness. Thus, there is the urgent need to propose, agree, and use a common methodology for the development of routing algorithms.

Συγκεκριμένα εννοώ τις πριν και μετά από τον Μυστικό Δείπνο ενέργειες του Χριστού, που παραπέμπουν στη Θεία Ευχαριστία Εδώ συγκαταλέγω α) τον χορτασμό των πεντακισχιλίων και των τετρακισχιλίων, β) τις παραβολές των Δείπνων, γ) τα λόγια του Χριστού σχετικά με τους όρους: «άρτος ο επιούσιος», «οίνος», και «μόσχος ο σιτευτός», δ) τον Μυστικό Δείπνο, ε) τη μεταναστάσιμη εμφάνιση του Χριστού στους Εμμαούς. Αρχικά, οι διηγήσεις των πεντακισχιλίων αναφέρονται στα λόγια του Χριστού, στους ευχαριστιακούς όρους που ο ίδιος εκφώνησε κατά το δείπνο, με σκοπό να πραγματοποιήσει την κλάση των πέντε άρτων και την ευλογία των δύο ιχθύων. Οι διηγήσεις των τετρακισχιλίων αναφέρονται στους ευχαριστιακούς όρους που ο Χριστός εκφώνησε κατά το δείπνο, με σκοπό να πραγματοποιήσει την κλάση των επτά άρτων και την ευλογία των λίγων ιχθύων. Στις παραβολές των δείπνων γίνεται λόγος για τον ευχαριστιακό άρτο. Έπειτα, όροι με ευχαριστιακή διάσταση είναι «άρτος ο επιούσιος», «οίνος» και «μόσχος ο σιτευτός». Οι διηγήσεις του Μυστικού Δείπνου αναφέρονται στους ευχαριστιακούς όρους με τους οποίους ο Χριστός πραγματοποίησε την κλάση του άρτου και την ευλογία του οίνου. Τέλος, η μεταναστάσιμη εμφάνιση του Χριστού στους Εμμαούς αναφέρεται στην κλάση του άρτου που πραγματοποίησε ο Χριστός ενώπιον του Κλέοπα και του άλλου μαθητή.
description: The eucharistic sites condensed gospels are the words and deeds of Christ mentioned directly or indirectly in the Eucharist. Specifically I mean before and after the Last Supper actions of Christ, referring to the Eucharist. Here I count a) satiety of the pentakischilion and tetrakischilion, b) barables of Dinners, c) Christ’s words on the conditions: “bread epiousios’’, “wine’’ and “the fattened calf’’, d) the Last Supper, e) the resurrection appearances of Christ to Emmaus. Initially, the narratives of pentakischilion referred to the words of Christ in the eucharistic terms he delivered at the dinner in order to hold the class of the five loaves and the two fish blessing. The narratives of tetrakischilion reported in eucharistic terms which Christ gave at the dinner in order to hold the class of the seven loaves and the blessing of a few fish. In the barables of Dinners referred to eucharistic bread. Τhen terms with eucharistic dimension is “bread epiousios’’, “wine’’ and “the fattened calf’’. The narratives of the Last Supper are listed in eucharistic terms on which Christ performed the breaking of the bread and the wine blessing. Finally, the resurrection appearances of Christ to Emmaus refers to the breaking of the bread made by Christ before Cleopas and another disciple.
Absolute Broadband Polarization Behaviour of PSR B0329+54: A Glimpse of the Core Emission Process

description: In this paper we report multifrequency single pulse polarization observations of the PSR B0329+54 normal mode using the Giant Meterwave Radio Telescope at 325 and 610 MHz and the Effelsberg Observatory at 2695 MHz. Our observations show that towards the central part of the polarization position-angle traverse there is an unusual ``arc''-like structure, which is comprised of a broadband ``kink'' and a frequency-dependent ``spot.'' The features are intimately connected with the intensity dependence of the core component: the stronger emission arrives earlier and its linear polarization is displaced farther along the ``kink''. Moreover, at high intensities, the circular polarization is --/+ antisymmetric; the nearly complete positive circular is characteristic of the weaker, later core subpulses. We find that the ``kink'' emission is associated with the extraordinary (X) propagation mode, and hence propagation effects do not appear capable of producing the core component's broadband, intensity-dependent emission. Rather, the overall evidence points to a largely geometric interpretation in which the ``kink'' provides a rare glimpse of the accelerating cascade or height-dependent amplifier responsible for the core radiation.

description: The formation of filaments in molecular clouds is an important process in star formation. Hub-filament systems (HFSs) are a transition stage connecting parsec-scale filaments and proto-clusters. Understanding the origin of HFSs is crucial to reveal how star formation proceeds from clouds to cores. Here, we report JCMT POL-2 850 $μ$m polarization and IRAM 30-m C$^{18}$O (2-1) line observations toward the massive HFS G33.92+0.11. The 850 $μ$m continuum map reveals four major filaments converging to the center of G33.92+0.11 with numerous short filaments connecting to the major filaments at local intensity peaks. We estimate the local orientations of filaments, magnetic field, gravity, and velocity gradients from observations, and we examine their correlations based on their local properties. In the high-density areas, our analysis shows that the filaments tend to align with the magnetic field and local gravity. In the low-density areas, we find that the local velocity gradients tend to be perpendicular to both the magnetic field and local gravity, although the filaments still tend to align with local gravity. A global virial analysis suggests that the gravitational energy overall dominates the magnetic and kinematic energy. Combining local and global aspects, we conclude that the formation of G33.92+0.11 is predominantly driven by gravity, dragging and aligning the major filaments and magnetic field on the way to the inner dense center. Traced by local velocity gradients in the outer diffuse areas, ambient gas might be accreted onto the major filaments directly or via the short filaments.

description: Sutured Floer homology, denoted by SFH, is an invariant of balanced sutured manifolds previously defined by the author. In this paper we give a formula that shows how this invariant changes under surface decompositions. In particular, if (M, γ)--> (M', γ') is a sutured manifold decomposition then SFH(M',γ') is a direct summand of SFH(M, γ). To prove the decomposition formula we give an algorithm that computes SFH(M,γ) from a balanced diagram defining (M,γ) that generalizes the algorithm of Sarkar and Wang. As a corollary we obtain that if (M, γ) is taut then SFH(M,γ) is non-zero. Other applications include simple proofs of a result of Ozsvath and Szabo that link Floer homology detects the Thurston norm, and a theorem of Ni that knot Floer homology detects fibred knots. Our proofs do not make use of any contact geometry. Moreover, using these methods we show that if K is a genus g knot in a rational homology 3-sphere Y whose Alexander polynomial has leading coefficient a_g non-zero and if the rank of \hat{HFK}(Y,K,g) < 4 then the knot complement admits a depth < 2 taut foliation transversal to the boundary of N(K).

description: We develop ZnO/p-Si photodetectors by atomic layer deposition (ALD) of ZnO thin films on laser-microstructured silicon and we investigate their electrical and optical behavior, demonstrating high sensitivity and broadband operation. Microstructured p-type silicon was obtained by ns-laser irradiation in SF6 gas, which results in the formation of quasi-ordered and uniform microspikes on the silicon surface. The irradiated silicon contains sulfur impurities, which extend its absorbance to the near infrared. A thin film of ZnO was conformally deposited on the microstructured silicon substrates by ALD. Photoluminescence measurements indicate high crystalline quality of the ZnO film after annealing. Current-voltage (I-V) measurements of the ZnO/p-Si heterodiodes in dark show a non-linear behavior with unusual high current values in reverse bias. Under illumination photocurrent is observed for reverse bias, even for wavelengths below the silicon bandgap in the case of the laser-microstructured photodetectors. Higher current values are measured for the microstructured photodetectors, compared to planar ones. Photoconductivity measurements show enhanced responsivity across the UV-Vis-NIR spectral range for the laser-microstructured devices, due to their increased surface area and light absorption.

description: The present thesis focuses on the definition of the principle of non-review of the foreign judgments as to substance (prohibition of revision au fond) during their recognition and enforcement in Greece. At first, the writer attempts to approach the circumstances under which the substantive re-examination of the content of the foreign judgment was abolished in the legal systems worldwide, among which the Greek legal system, where limited review on the substance of the foreign judgment was applied under the Maurer’s Code of Civil Procedure. Moreover, the writer examines the content of the rule of non-review, issue which is the core of the problem. Subsequently, the limits of the principle of non-review as to substance are presented by linking the rule with the most frequently occurring recognition obstacles internationally, i.e. the lack of jurisdiction, the violation of the right to be heard and the impediment of public policy. Finally, the writer attempts to find the practical consequences of the rule of non-review as to substance in the field of the defense of the debtor against the enforcement proceedings, emphasizing on the substantive objections that the debtor may propose against the enforced claim.

description: Στην παρούσα μεταπτυχιακή εργασία παρουσιάζεται η ζοφερή κατάσταση που διαμορφώθηκε για τους χριστιανικούς πληθυσμούς, μέσα στην Οθωμανική Αυτοκρατορία, μετά την πτώση της Κωνσταντινουπόλεως και το σημαντικό ρόλο που διαδραμάτισε η Εκκλησία για τη στήριξη των υπόδουλων. Ειδικότερα, αναλύονται οι συνθήκες ζωής των χριστιανών σε σχέση με τους μουσουλμάνους, καθώς και τα μέσα που χρησιμοποίησαν οι κατακτητές για να αφομοιώσουν τους χριστιανικούς πληθυσμούς που είχαν υπό την κατοχή τους. Από την άλλη, αναδεικνύονται οι τρόποι αντίδρασης των υπόδουλων απέναντι σ΄ αυτές τις πρακτικές των κατακτητών. Έτσι, εμφανίζονται από τη μια οι Νεομάρτυρες, οι οποίοι αντιπροσωπεύουν την παθητική, αλλά συνάμα σθεναρή αντίσταση κατά της πρακτικής του εξισλαμισμού, ενώ από την άλλη αναδεικνύονται οι Εθνομάρτυρες, οι οποίοι εκφράζουν τη δυναμική αντίσταση του λαού, που δεν διστάζουν, όταν και οι διεθνείς συγκυρίες το απαιτούν, να πάρουν τα όπλα και να θυσιαστούν για την ελευθερία του Έθνους. Στα χρόνια του Αλή Πασά των Ιωαννίνων, ο οποίος στα τριάντα τέσσερα χρόνια της κυριαρχίας του σε Ήπειρο και Μακεδονία κατάφερε να καταδυναστεύσει σκληρά τους χριστιανικούς πληθυσμούς, αναδεικνύονται Νεομάρτυρες και Εθνομάρτυρες, οι οποίοι με τη θυσία τους αποτέλεσαν φάρο ελπίδας, τόσο για την διατήρηση της χριστιανικής πίστης, όσο και την αποτίναξη του ζυγού.
description: This thesis illustrates the dismal situation the Christian population faced during the Ottoman Empire after Istanbul’s downfall and also the Church’s great role in supporting the enslaved. In specific, it analyses the Christians’ living conditions compared with the Muslims’, as well as the means used by the conquerors in order to assimilate the Christian population they had under their occupation. It also highlights the reactions of the enslaved to the conquerors’ practices. So on the one hand the Neomartyrs represent the passive yet strong resistance against Islamization, where on the other hand the Martyrs of the nation express the dynamic resistance of people who did not hesitate, due to international circumstances, to go into battle and sacrifice themselves for the freedom of their nation. Ali Pasha of Ioannina dominated Epirus, Macedonia and the Christian population living there for thirty four years. In this era, the Neomartyrs and the Martyrs of the nation stand out and through their sacrifice they gave hope, so much for the maintenance of the Christian faith, as for the nation’s freedom.

We provide a sufficient condition for the solution to be positive and analyze the range of application of our method for elliptic problems with polynomial nonlinearities. We present numerical examples where our method is applied to some important problems.

description: This work concerns the loss of energy of a material system due to gravitational radiation in Einstein-aether theory-an alternative theory of gravity in which the metric couples to a dynamical, timelike, unit-norm vector field. Derived to lowest post-Newtonian order are waveforms for the metric and vector fields far from a nearly Newtonian system and the rate of energy radiated by the system. The expressions depend on the quadrupole moment of the source, as in standard general relativity, but also contain monopolar and dipolar terms. There exists a one-parameter family of Einstein-aether theories for which only the quadrupolar contribution is present, and for which the expression for the damping rate is identical to that of general relativity to the order worked to here. This family cannot yet be declared observationally viable, since effects due to the strong internal fields of bodies in the actual systems used to test the damping rate are not included.

description: This thesis reviews the objectives of existing and proposed policies affecting bicycle transportation in the Greater Vancouver region and attempts to evaluate the level of success these policies will have in achieving these objectives. In the process, mechanisms for implementation will be considered as well as reaction to specific policies as indicated from survey results and discussions with bicycling advocates in this region. Many of the policies that will be effective, especially those at the regional level, are aimed at making long-distance bicycle trips a more viable option. It is argued that trips of greater distance will appeal mostly to experienced, well-conditioned bicyclists and that these policies will have limited effect in increasing the overall number of people using bicycles for transportation. In order to effectively address the issue of making bicycles a more viable mode of transportation, there first needs to be a change in the patterns of land use i n this region followed by the provision of incentives for changing attitudes about transportation modes. The needs and concerns of casual bicycle riders who usually use their bicycles only for recreational purposes must be addressed. Without a fundamental shift in the way in which land is used and developed in this region and an accompanying program to precipitate a shift in transportation behaviour, the effects of bicycle policies on their own will be token at best.

description: Leadership and followership are essential parts of collective decision and organization in social animals, including humans. In nature, relationships of leaders and followers are dynamic and vary with context or temporal factors. Understanding dynamics of leadership and followership, such as how leaders and followers change, emerge, or converge, allows scientists to gain more insight into group decision-making and collective behavior in general. However, given only data of individual activities, it is challenging to infer the dynamics of leaders and followers. In this paper, we focus on mining and modeling frequent patterns of leading and following. We formalize new computational problems and propose a framework that can be used to address several questions regarding group movement. We use the leadership inference framework, mFLICA, to infer the time series of leaders and their factions from movement datasets and then propose an approach to mine and model frequent patterns of both leadership and followership dynamics. We evaluate our framework performance by using several simulated datasets, as well as the real-world dataset of baboon movement to demonstrate the applications of our framework. These are novel computational problems and, to the best of our knowledge, there are no existing comparable methods to address them. Thus, we modify and extend an existing leadership inference framework to provide a non-trivial baseline for comparison. Our framework performs better than this baseline in all datasets. Our framework opens the opportunities for scientists to generate testable scientific hypotheses about the dynamics of leadership in movement data.

description: We report on a class of configurations of permanent magnets on an atom chip for producing 1D and 2D periodic arrays of magnetic microtraps with non-zero potential minima and variable barrier height for trapping and manipulating ultracold atoms and quantum degenerate gases. We present analytical expressions for the relevant physical quantities and compare them with our numerical results and with some previous numerical calculations. In one of the configurations of permanent magnets, we show how it is possible by changing the angle between the crossed periodic arrays of magnets to go from a 1D array of 2D microtraps to a 2D array of 3D microtraps and thus to continuously vary the barrier heights between the microtraps. This suggests the possibility of performing a type of `mechanical' BEC to Mott insulator quantum phase transition in a magnetic lattice. We also discuss a configuration of magnets which could realize a two-qubit quantum gate in a magnetic lattice.

description: The heat capacity of low-dimensional spin systems is studied using theoretical and numerical techniques. Keeping only two energy states, the system is mapped onto the two -level-system (TLS) model. Using the low temperature Lanczos method, it is confirmed that the behavior of $T_{M}$ and the energy gap as functions of the control parameter is the same in the two models studied; a conclusion that can probably be extrapolated to the general case of any system that possesses an energy gap.

description: Obtaining the magnetic field vector accurately in the solar atmosphere is essential for studying changes in field topology during flares and to reliably model space weather. We tackle this problem by applying various inversion methods to a confined X2.2 flare in NOAA AR 12673 on September 6, 2017, comparing the photospheric and chromospheric magnetic field vector with those from two numerical models of this event. We obtain the photospheric field from Milne-Eddington (ME) and (non-)local thermal equilibrium (non-LTE) inversions of Hinode SOT/SP Fe I 6301.5Å and 6302.5Å. The chromospheric field is obtained from a spatially-regularised weak field approximation (WFA) and non-LTE inversions of Ca II 8542Å observed with CRISP at the Swedish 1-m Solar Telescope. The LTE- and non-LTE-inferred photospheric field components are strongly correlated throughout the atmosphere, with stronger field and higher temperatures in the non-LTE inversions. For the chromospheric field, the non-LTE inversions correlate well with the spatially-regularised WFA. We find strong-field patches of over 4.5 kG in the photosphere, co-located with similar concentrations exceeding 3 kG in the chromosphere. The obtained field strengths are up to 2-3 times higher than in the numerical models, with more concentrated and structured photosphere-to-chromosphere shear close to the polarity inversion line. The LTE and non-LTE Fe I inversions yield essentially the same photospheric field, while ME inversions fail to reproduce the field vector orientation where Fe I is in emission. Our inversions confirm the locations of flux rope footpoints that are predicted by numerical models. However, pre-processing and lower spatial resolution lead to weaker and smoother field in the models than what the data indicate. This emphasises the need for higher spatial resolution in the models to better constrain pre-eruptive flux ropes.

description: We present the results of the first multi-scale N-Body+SPH simulations of merging galaxies containing central supermassive black holes (SMBHs) and having a spatial resolution of only a few parsecs. Strong gas inflows associated with equal-mass mergers produce non-axisymmetric nuclear disks with masses of order $10^9 M_{\odot}$, resolved by about $10^6$ SPH particles. Such disks have sizes of several hundred parsecs but most of their mass is concentrated within less than $50$ pc. We find that a close SMBH pair forms after the merger. The separation of the two SMBHs then shrinks further owing to dynamical friction against the predominantly gaseous background. The orbits of the SMBHs decay down to the minimum resolvable scale in a few million years for an ambient gas temperature and density typical of a region undergoing a starburst. These results suggest the initial conditions necessary for the eventual coalescence of the two holes arise naturally from the merging of two equal-mass galaxies whose structure and orbits are consistent with the predictions of the $Λ$CDM model. Our findings have important implications for planned gravitational wave detection experiments such as {\it LISA}.

description: This thesis examines landscape, as perceived through the activity of paragliding or hang gliding and attempts to understand the diversity of the aerial landscape. The goal is to explore the possibilities of landscape design and planning within the context of landscape architecture, for the creation of parks for relevant sport activities. Based on landscape analysis from an ecological, aesthetic and socio-cultural perspective, proposals are formed in order to enhance and protect the landscape identity in terms of sustainable development. Emphasis is laid, amongst others, on the need for safety in design of the necessary infrastructure. The theoretical approach is followed by applied research in the case of Mount Voras. The landscape of the region is analyzed, followed by the proposal for a flight park. Based on the characteristics of the landscape, design proposals concerning new flying routes are made, in order to highlight and promote the unique aerial-landscape. In addition, a supportive network of multifunctional public spaces suitable for the development of these activities is included, in the context of promoting sustainable forms of tourism in the area.

description: The evolution of nuclear shell structure is investigated for the first time within density-dependent relativistic Hartree-Fock theory and the role of $π$-exchange potential is studied in detail. The energy differences between the neutron orbits $\Lrb{\nu1h_{9/2},ν1i_{13/2}}$ in the N=82 isotones and between the proton ones $\Lrb{\pi1g_{7/2},\pi1h_{11/2}}$ in the Z=50 isotopes are extracted as a function of neutron excess $N-Z$. A kink around $Z = 58$ for the N=82 isotones is found as an effect resulting from pion correlations. It is shown that the inclusion of $π$-coupling plays a central role to provide realistic isospin dependence of the energy differences. In particular, the tensor part of the $π$-coupling has an important effect on the characteristic isospin dependence observed in recent experiments.

description: We study the $τ^- \to ν_τ π^{-}π^{0}\ell^{+}\ell^{-}$ ($\ell=e,\,μ$) decays, which are $O(α^2)$-suppressed with respect to the dominant di-pion tau decay channel. Both the inner-bremsstrahlung and the structure- (and model-)dependent contributions are considered. In the $\ell=e$ case, structure-dependent effects are $\mathcal{O}(1\%)$ in the decay rate, yielding a clean prediction of its branching ratio, $2.3\times10^{-5}$, measurable with BaBar or Belle(-II) data. For $\ell=μ$, both contributions have similar magnitude and we get a branching fraction of $(1.6\pm0.3)\times10^{-7}$, reachable by the end of Belle-II operation. These decays allow to study the dynamics of strong interactions with simultaneous weak and electromagnetic probes; their knowledge will contribute to reducing backgrounds in lepton flavor/number violating searches.

description: This work details the problem of aerial target capture using multiple UAVs. This problem is motivated from the challenge 1 of Mohammed Bin Zayed International Robotic Challenge 2020. The UAVs utilise visual feedback to autonomously detect target, approach it and capture without disturbing the vehicle which carries the target. Multi-UAV collaboration improves the efficiency of the system and increases the chance of capturing the ball robustly in short span of time. In this paper, the proposed architecture is validated through simulation in ROS-Gazebo environment and is further implemented on hardware.
