description: We performed general relativistic, long-term, axisymmetric neutrino radiation hydrodynamics simulations for the remnant formed after the binary neutron star merger, which consist of a massive neutron star and a torus surrounding it. As an initial condition, we employ the result derived in a three-dimensional, numerical relativity simulation for the binary neutron star merger. We investigate the properties of neutrino-driven ejecta. Due to the pair-annihilation heating, the dynamics of the neutrino-driven ejecta is significantly modified. The kinetic energy of the ejecta is about two times larger than that in the absence of the pair-annihilation heating. This suggests that the pair-annihilation heating plays an important role in the evolution of the merger remnants. The relativistic outflow, which is required for driving gamma-ray bursts, is not observed because the specific heating rate around the rotational axis is not sufficiently high due to the baryon loading caused by the neutrino-driven ejecta from the massive neutron star. We discuss the condition for launching the relativistic outflow and the nucleosynthesis in the ejecta.

description: Constraints on couplings of several Beyond Standard Model Physics scenarios, mediated by massive intermediate particles including (1) Extra Z-prime, (2) New Light Spin-1 Boson, and (3) Charged Higgs Boson, are placed via neutrino-electron scattering channel to test Standard Model at low energy-momentum transfer regime. Data on $\barν_{e}-e$ and $ν_{e}-e$ scattering from the TEXONO and LSND Experiments, respectively, are used. Upper bounds to coupling constants of Flavor Conserving and Flavor Violating New Light Spin-1 Boson and Charged Higgs Boson with respect to different mediator masses are determined. The relevant parameter spaces are extended by allowing light mediators. New lower mass limits for extra Z-prime gauge boson models are also placed.

description: Two-body charmless hadronic $B_c$ decays involving a light $1^3\!P_2$-tensor($T$) meson are investigated for the first time within the framework of perturbative QCD(pQCD) at leading order, in which the other meson is the lightest pseudoscalar($P$) or vector($V$) state. The concerned processes can only occur through the pure weak annihilation topology in the standard model. We predict the CP-averaged branching ratios and polarization fractions of those considered decays in Cabibbo-Kobayashi-Maskawa(CKM) favored and suppressed modes. Phenomenologically, several modes$-$such as the $B_c \to K_2^*(1430) K$ and the CKM-favored $B_c \to TV-$have large decay rates of $10^{-6}$, which are expected to be detected at Large Hadron Collider experiments in the near future. Moreover, all of the $B_c \to TV$ modes are governed by the longitudinal amplitudes in the pQCD calculations and the corresponding fractions vary around $78\%$-$98\%$. A confirmation of these results could prove the reliability of the pQCD approach used here and further shed some light on the annihilation decay mechanism.

description: The observed spatio-temporal ciliary beat patterns on multiciliated epithelia are suspected to be the result of self-organizing processes on various levels. Here, we present an abstract epithelium model at the pluricellular level, which intends to make the self-organization of ciliary beating patterns as well as of the associated fluid transport across the airway epithelium plausible. Ciliated cells are modeled in terms of locally interacting oscillating two-state actuators. The local interactions among these boolean actuators are triggered by seeded mucus lumps. In the course of a simulation the actuators' state and the associated mucus velocity field self-organize in tandem. We suggest to consider the dynamics on multiciliated epithelia in the context of adaptive (boolean) networks. Within the framework of adaptive boolean networks ciliated cells represent the nodes and as the mucus establishes the local interactions among nodes, its distribution determines the topology of the network. Furthermore, we present the results and insights from comprehensive parameter studies. The results show evidence that so called deterministic update schemes, which are meant to represent intercellular signaling, lead to more realistic and robust dynamics and may therefore be favored by nature. Finally, we suppose that unciliated cells introduce a modular network topology on ciliated epithelia causing the self-organization taking place simultaneously in each "ciliated module". This reasoning provides the first consistent explanation for the meaning of the observed patchy expression patterns of the mucus modulation wave fields. Modularity may therefore be seen as a modular construction plan of nature for ciliated epithelia whose number of cells range over several order of magnitudes.
A rigourous demonstration of the validity of Boltzmann's scenario for the spatial homogenization of a freely expanding gas and the equilibration of the Kac ring

description: Boltzmann provided a scenario to explain why individual macroscopic systems composed of a large number $N$ of microscopic constituents are inevitably (i.e., with overwhelming probability) observed to approach a unique macroscopic state of thermodynamic equilibrium, and why after having done so, they are then observed to remain in that state, apparently forever. We provide here rigourous new results that mathematically prove the basic features of Boltzmann's scenario for two classical models: a simple boundary-free model for the spatial homogenization of a non-interacting gas of point particles, and the well-known Kac ring model. Our results, based on concentration inequalities that go back to Hoeffding, and which focus on the typical behavior of individual macroscopic systems, improve upon previous results by providing estimates, exponential in $N$, of probabilities and time scales involved.

description: A hard proximity-induced superconducting gap has recently been observed in semiconductor nanowire systems at low magnetic fields. However, in the topological regime at high magnetic fields, a soft gap emerges and represents a fundamental obstacle to topologically protected quantum information processing with Majorana bound states. Here we show that in a setup of double Rashba nanowires that are coupled to an s-wave superconductor and subjected to an external magnetic field along the wires, the topological threshold can be significantly reduced by the destructive interference of direct and crossed-Andreev pairing in this setup, precisely down to the magnetic field regime in which current experimental technology allows for a hard superconducting gap. We also show that the resulting Majorana bound states exhibit sufficiently short localization lengths, which makes them ideal candidates for future braiding experiments.

description: A single-ion reservoir has been tested, and characterized in order to be used as a highly sensitive optical detector of electric signals arriving at the trapping electrodes. Our system consists of a single laser-cooled $^{40}$Ca$^+$ ion stored in a Paul trap with rotational symmetry. The performance is observed through the axial motion of the ion, which is equivalent to an underdamped and forced oscillator. Thus, the results can be projected also to Penning traps. We have found that, for an ion oscillator temperature $T_{\scriptsize{\rm axial}}\lesssim 10$~mK in the forced-frequency range $ω_z =2π\times (80,200$~kHz), the reservoir is sensitive to a time-varying electric field equivalent to an electric force of $5.3(2)$~neV/$μ$m, for a measured quality factor $Q=3875(45)$, and a decay time constant $γ_z=88(2)$~s$^{-1}$. This method can be applied to measure optically the strength of an oscillating field or induced (driven) charge in this frequency range within times of tens of milliseconds. Furthermore the ion reservoir has been proven to be sensitive to electrostatic forces by measuring the ion displacement. Since the heating rate is below $0.3$~$μ$eV/s, this reservoir might be used as optical detector for any ion or bunch of charged particles stored in an adjacent trap.

MULTIGENERATIONAL HOUSEHOLDS IN ITALY. WHEN ADULT CHILDREN RETURN TO PARENTAL HOME, DETERMINANTS AND IMPLICATIONS
Creators: name: LODETTI, PATRIZIO

description: The general aim of this thesis is to establish a foundational understanding of the phenomenon of young people returning to the parental home (boomerangers) in Italy, unfolding its main determinants and understanding whether and to what extent it was affected by the economic crises of 2008. Using nine waves (from 2006 to 2014) of the Eurostat Longitudinal Survey on Income and Living Conditions was possible to compare the period of the crisis (2008-2012) with the one before (2006-2007) and the one after (2013-2014). The longitudinal design of the survey allowed to situate returning home phenomenon in the framework of life-course transitions, inquiring how it is related to other individual?s life course turning points. Furthermore, the panel-data structure of the dataset made possible the use of longitudinal models. The empirical analysis is mainly oriented to define the effect of economic uncertainty on the residential careers of individuals in the 18-34 age group, specifically on their return to the parental home. Since residential careers are embedded in social and cultural contexts which reproduce specific mechanisms of social inequalities, the analysis is also oriented to understand the role that individual characteristics (mainly educational level, gender, and age), social class and familiar resources (household disposable income and tenure status) have on mediating the returning home phenomena. The main findings suggest that, in Italy, the quota of young people boomeranging into the parental home is relevant (especially for those in their 20s). The analysis highlights a significant rising trend during the period of economic crises, especially in the second more severe phase (from the half of 2010 to 2012), emphasizing the determinant effect of economic hardships (condition of unemployment and inactivity) and marital instability. Regarding the economic transition markers, it appears that is not so much the type of shift in the employment status (like getting unemployed), but the change in employment status itself, to be a good predictor of home returning. The most relevant findings, however, are about the interaction between social class and economic status. What primarily emerges, is that, in a period of economic uncertainty and hardship, family serves as a form of protection mainly for young people of the high class (in a status of unemployment/inactivity), who get residential support until the achievement of a high-level and stable job which can fulfill their expectations.

description: Scalar tops in the supersymmetric model affect the potential of the standard model-like Higgs at the quatum level. In light of the equivalence theorem, the deviation of the potential from the standard model can be traced by longitudinal gauge bosons. In this work, high energy longitudinal W boson scattering is studied in a TeV-scale scalar top scenario. O(1-10%) deviation from the standard model prediction in the differential cross section is found depending on whether the observed Higgs mass is explained only by scalar tops or by additional contributions at a higher scale.

description: We show that each algebraic representation of a matroid $M$ in positive characteristic determines a matroid valuation of $M$, which we have named the {\em Lindström valuation}. If this valuation is trivial, then a linear representation of $M$ in characteristic $p$ can be derived from the algebraic representation. Thus, so-called rigid matroids, which only admit trivial valuations, are algebraic in positive characteristic $p$ if and only if they are linear in characteristic $p$. To construct the Lindström valuation, we introduce new matroid representations called flocks, and show that each algebraic representation of a matroid induces flock representations.

description: In this paper we discuss a disordered $d$-dimensional Euclidean $λφ^{4}$ model. The dominant contribution to the average free energy of this system is written as a series of the replica partition functions of the model. In each replica partition function, using the saddle-point equations and imposing the replica symmetric ansatz, we show the presence of a spontaneous symmetry breaking mechanism in the disordered model. Moreover, the leading replica partition function must be described by a large-$N$ Euclidean replica field theory. We discuss finite temperature effects considering periodic boundary condition in Euclidean time and also using the Landau-Ginzburg approach. In the low temperature regime we prove the existence of $N$ instantons in the model.

description: Motivated by the recent progress on the spin-orbit-coupled triangular lattice spin liquid candidate YbMgGaO4, we carry out a systematic projective symmetry group analysis and mean-field study of candidate U(1) spin liquid ground states. Due to the spin-orbital entanglement of the Yb moments, the space group symmetry operation transforms both the position and the orientation of the local moments, and hence brings different features for the projective realization of the lattice symmetries from the cases with spin-only moments. Among the eight U(1) spin liquids that we find with the fermionic parton construction, only one spin liquid state, that was proposed and analyzed in Yao Shen, et al, Nature 540, 559-562 (2016) and labeled as U1A00 in the present work, stands out and gives a large spinon Fermi surface and provides a consistent explanation for the spectroscopic results in YbMgGaO4. Further connection of this spinon Fermi surface U(1) spin liquid with YbMgGaO4 and the future directions are discussed. Finally, our results may apply to other spin-orbit-coupled triangular lattice spin liquid candidates, and more broadly, our general approach can be well extended to spin-orbit-coupled spin liquid candidate materials.

description: Around 2006 the signal processing community was thrilled when the concept of Compressed Sensing was brought forward. While according to the long-established Nyquist-Shannon theorem, the sampling rate for signals must be at least twice as high as the highest relevant frequency in the signal, with Compressed Sensing lower average sampling rates become suitable. As a more general toolkit, Compressed Sensing allows for merging sensing and compression in a single step. In other words, only a tiny amount of data needs to be sensed but a huge amount of information can be reconstructed from this data. While Compressed Sensing already has been successfully applied in some areas, mainly in medical scanning where it helps to reduce the exposure to radiation, adaptation to new application areas is relatively slow. We identify two causes that slow down the adaption and contribute to overcoming these obstacles: firstly, the adaption of Compressed Sensing requires interdisciplinary thinking even more than for many other new technologies: Compressed Sensing itself comes from the field of signal processing, the application adds a second field. The automatized processing of the data always touches the field of computer science and lastly, designing Compressed Sensing solutions often requires a modification or redesign of measurement hardware, touching the fields of electronics and sometimes mechanics. We address this issue by supplying a more structured approach for designing Compressed Sensing solutions. Secondly, Compressed Sensing usually performs a lossy compression on real world data. Not knowing the quality of the solution limits its usability. We address this issue by supplying a list of potential metrics for assessing the quality of the solution and evaluate their performance for various datasets. Along the way, we develop two Compressed Sensing solutions in the application area of Precision Agriculture: The first is Compressive Field Estimate (CFE), a method for improving the remote estimate of a scalar field based on limited data supplied by a moving probe such as a combine harvester. The second is Multi- to Hyperspectral Sensor Network (M2HSN), a wireless sensor network that records light spectra at mediocre spectral resolution and allows for increasing the spectral resolution. For the M2HSN, we discuss different designs of the sensor nodes and different approaches for increasing the resolution. Those are simulatively evaluated on different datasets and in a real-world prototype.

description: Long-range dependence (LRD) has been observed in a variety of phenomena in nature, and for several years also in the spiking activity of neurons. Often, this is interpreted as originating from a non-Markovian system. Here we show that a purely Markovian integrate-and-fire (IF) model, with a noisy slow adaptation term, can generate interspike intervals (ISIs) that appear as having LRD. However a proper analysis shows that this is not the case asymptotically. For comparison, we also consider a new model of individual IF neuron with fractional (non-Markovian) noise. The correlations of its spike trains are studied and proven to have LRD, unlike classical IF models. On the other hand, to correctly measure long-range dependence, it is usually necessary to know if the data are stationary. Thus, a methodology to evaluate stationarity of the ISIs is presented and applied to the various IF models. We explain that Markovian IF models may seem to have LRD because of non-stationarities.

Δεδομένου ότι η άνεση των εργαζομένων είναι βασική παράμετρος, η βελτίωση των συνθηκών άνεσης έχει γίνει ένα μέσο αύξησης της αποδοτικότητας και της παραγωγικότητας. στο γραφείο ή στην τάξη.

Οι προσόψεις των κτιρίων θεωρούνται πλέον ως μηχανισμοί δυναμικής αλληλεπίδρασης παρά ως ασπίδες προστασίας από το εξωτερικό περιβάλλον.

description: We investigated the electronic states of the quasi-one-dimensional organic conductors $δ'_{P}$-(BPDT-TTF)$_2$ICl$_2$ and $δ'_{C}$-(BPDT-TTF)$_2$ICl$_2$, both of which are insulating at room temperature owing to strong electron correlations. Through measurements of electrical resistivity, optical conductivity, and magnetic susceptibility, as well as band-structure calculations, we have revealed that the two materials possess completely different ground states, even though they have the same chemical composition and stacking configuration of the donor molecules. We have found that the $δ_P'$-type salt with an effective half-filled band behaves as a dimer-Mott (DM) insulator and exhibits a nonmagnetic transition at 25 K, whereas the $δ'_C$-type salt with a 3/4-filled band shows a charge ordering (CO) transition just above room temperature and becomes nonmagnetic below 20 K. The optical spectra of the $δ_P'$-type salt are composed of two characteristic bands due to intra- and interdimer charge transfers, supporting the DM insulating behavior arising from the strong on-site Coulomb interaction. By contrast, in the $δ'_C$-type salt, a single band characterizing the formation of CO arising from the off-site Coulomb interactions is observed. Upon lowering the temperature, the shape of the optical spectra in the $δ_C'$-type salt becomes asymmetric and shifts to much lower frequencies, suggesting the emergence of domain-wall excitations with fractional charges expected in a one-dimensional CO chain. The temperature dependence of the magnetic susceptibility of the $δ_P'$-type salt is well described by a 2D spin-1/2 Heisenberg AFM model on an anisotropic square lattice in the dimerized picture, while in the $δ_C'$-type salt, it can be explained by a 2D spin-1/2 Heisenberg AFM model on an anisotropic honeycomb lattice formed in the CO state.

description: We propose a new approach based on the Lindblad and Bloch equations for the density matrix to the problem of a neutron into an antineutron conversion. We consider three strategies to search for conversion: experiments with trapped neutrons, oscillations in nuclei, and quasi-free propagation. We draw a distinction between $n\bar{n}$ oscillations in which the probability that a neutron transforms into an antineutron depends on time according to the sine-square law and the non-oscillatory overdamped $n\bar{n}$ conversion. We show that in all three cases decoherence due to the interaction with the environment leads to non-oscillatory evolution.

Subjects: subject: Molecular evolution, yeast, systems biology, protein interaction.

description: Gene and protein interaction networks have evolved to precisely specify cell fates and functions. Here, we analyse whether the architecture of these networks affects evolvability. We find evidence to suggest that in yeast these networks are mainly acyclic, and that evolutionary changes in these parts do not affect their global dynamic properties. In contrast, feedback loops strongly influence dynamic behaviour and are often evolutionarily conserved. Feedback loops are often found to reside in a clustered manner by means of coupling and nesting with each other in the molecular interaction network of yeast. In these clusters some feedback mechanisms are biologically vital for the operation of the module and some provide auxiliary functional assistance. We find that the biologically vital feedback mechanisms are highly conserved in both transcription regulation and protein interaction network of yeast. In particular, long feedback loops and oscillating modules in protein interaction networks are found to be biologically vital and hence highly conserved. These data suggest that biochemical networks evolve differentially depending on their structure with acyclic parts being permissive to evolution while cyclic parts tend to be conserved.

description: Chronic obstructive pulmonary disease (COPD) is a lung disease which can be quantified using chest computed tomography (CT) scans. Recent studies have shown that COPD can be automatically diagnosed using weakly supervised learning of intensity and texture distributions. However, up till now such classifiers have only been evaluated on scans from a single domain, and it is unclear whether they would generalize across domains, such as different scanners or scanning protocols. To address this problem, we investigate classification of COPD in a multi-center dataset with a total of 803 scans from three different centers, four different scanners, with heterogenous subject distributions. Our method is based on Gaussian texture features, and a weighted logistic classifier, which increases the weights of samples similar to the test data. We show that Gaussian texture features outperform intensity features previously used in multi-center classification tasks. We also show that a weighting strategy based on a classifier that is trained to discriminate between scans from different domains, can further improve the results. To encourage further research into transfer learning methods for classification of COPD, upon acceptance of the paper we will release two feature datasets used in this study on http://bigr.nl/research/projects/copd

description: The computation of the Noether numbers of all groups of order less than thirty-two is completed. It turns out that for these groups in non-modular characteristic the Noether number is attained on a multiplicity free representation, it is strictly monotone on subgroups and factor groups, and it does not depend on the characteristic. Algorithms are developed and used to determine the small and large Davenport constants of these groups. For each of these groups the Noether number is greater than the small Davenport constant, whereas the first example of a group whose Noether number exceeds the large Davenport constant is found, answering partially a question posed by Geroldinger and Grynkiewicz.

Relative velocities in bidisperse turbulent suspensions

description: We investigate the distribution of relative velocities between small heavy particles of different sizes in turbulence by analysing a statistical model for bidisperse turbulent suspensions, containing particles with two different Stokes numbers. This number, ${\rm St}$, is a measure of particle inertia which in turn depends on particle size. When the Stokes numbers are similar, the distribution exhibits power-law tails, just as in the case of equal ${\rm St}$. The power-law exponent is a non-analytic function of the mean Stokes number $\overline{\rm St}$, so that the exponent cannot be calculated in perturbation theory around the advective limit. When the Stokes-number difference is larger, the power law disappears, but the tails of the distribution still dominate the relative-velocity moments, if $\overline{\rm St}$ is large enough.

description: RESUMO

Objetivo: Relatar e discutir o restabelecimento da função e estética por meio de um caso clínico de tratamento integrado perio-endo-prótese. Detalhamento de caso: Paciente de 50 anos, gênero feminino, procurou a clínica Odontológica da Universidade Federal do Piauí, em razão do descontentamento estético do seu sorriso. O exame clínico mostrou coroas desadaptadas e desnível da margem gengival dos dentes 11, 21 e 23, o que determinou um planejamento de aumento de coroa clínica nos mesmos. Após exame radiográfico constatou-se a necessidade de reintervenção endodôntica do dente 11 e pulpectomia no dente 21. Decorridos 30 dias após a cirurgia e reembasamentos dos provisórios, realizou-se os tratamentos endodônticos. Em seguida os condutos foram preparados para cimentação dos pinos de fibra de vidro, confecção de provisórios para posterior instalação de coroas definitivas de cerâmica. Considerações finais: Diante do exposto, considera-se que o planejamento integrado e a utilização de materiais e técnicas adequados permitem ao dentista generalista reabilitar o paciente de forma eficaz com um excelente resultado estético e satisfação do paciente.

description: We identify the parameter regions of the phenomenological minimal supersymmetric standard model (pMSSM) with the minimal possible fine-tuning. We show that the fine-tuning of the pMSSM is not large, nor under pressure by LHC searches. Low sbottom, stop and gluino masses turn out to be less relevant for low fine-tuning than commonly assumed. We show a link between low fine-tuning and the dark matter relic density. Fine-tuning arguments point to models with a dark matter candidate yielding the correct dark matter relic density: a bino-higgsino particle with a mass of $35-155$ GeV. Some of these candidates are compatible with recent hints seen in astrophysics experiments such as Fermi-LAT and AMS-02. We argue that upcoming direct search experiments, such as XENON1T, will test all of the most natural solutions in the next few years due to the sensitivity of these experiments on the spin-dependent WIMP-nucleon cross section.

description: Σύγχρονες μελέτες καταδεικνύουν πως οι εκπαιδευτικοί αποτελούν μία επαγγελματική κατηγορία υψηλού κινδύνου όσον αφορά την εργασιακή παρενόχληση. Τα θύματα εκφοβισμού αντιμετωπίζουν μακροχρόνιες επιπτώσεις, όπως ψυχοκοινωνικά και σωματικά προβλήματα, άγχος, κατάθλιψη, επαγγελματική εξουθένωση. Η σημαντικότητα των επιπτώσεων του φαινομένου αποτέλεσε την αφετηρία του ερευνητικού προβληματισμού της παρούσας εργασίας. Ως σκοπός ορίζεται η διερεύνηση του φαινομένου της εργασιακής παρενόχλησης στους εκπαιδευτικούς της Δευτεροβάθμιας Εκπαίδευσης στο Νομό Ευβοίας. Επιμέρους ερευνητικοί στόχοι είναι η εξέταση της συχνότητας εμφάνισης του εργασιακού εκφοβισμού στα σχολεία του Νομού Ευβοίας, η προβολή των στρατηγικών διαχείρισης των περιστατικών που υιοθετούνται από τους εκπαιδευτικούς, καθώς και η παρουσίαση των αντιλήψεων των εκπαιδευτικών ως προς την επίδραση του σχολικού κλίματος και της σχολικής ηγεσίας, λαμβάνοντας υπόψη μία σειρά δημογραφικών μεταβλητών. Τα αποτελέσματα του ερευνητικού μέρους προέρχονται από την εκπόνηση ποσοτικής έρευνας σε δείγμα 199 εκπαιδευτικών (129 γυναίκες και 70 άντρες) στο Νομό της Εύβοιας. Διαπιστώθηκε πως ο βαθμός στον οποίο συναντώνται περιστατικά εργασιακού εκφοβισμού στα σχολεία είναι γενικά χαμηλός, ενώ τα όποια φαινόμενα εργασιακής παρενόχλησης παρατηρούνται κατά των εκπαιδευτικών, φαίνεται να αποτελούν μεμονωμένα περιστατικά. Συμπερασματικά, διαπιστώνεται από τα ευρήματα της παρούσας έρευνας, ότι οι κύριοι επιδρώντες παράγοντες εμφάνισης του φαινομένου είναι το σχολικό κλίμα και η σχολική ηγεσία, ενώ από τις ατομικές μεταβλητές φαίνεται το φύλο να είναι καθοριστική μεταβλητή, σε αντίθεση με την ηλικία και τα χρόνια προϋπηρεσίας που δε δείχνουν να επηρεάζουν σημαντικά την εμφάνιση και κλιμάκωση του φαινομένου. Οι κυριότερες καταχρηστικές συμπεριφορές που αναφέρθηκαν από τα θύματα είναι ο υπερβολικός φόρτος εργασίας αλλά και πως αγνοούνταν οι απόψεις και οι ιδέες τους, που φαίνεται να πηγάζουν κυρίως από τους συναδέλφους και σε παρόμοια χαμηλότερα ποσοστά από το διευθυντή της σχολικής μονάδας, τους μαθητές και τους γονείς. Επιπλέον, καταγράφηκαν οι κυριότερες στρατηγικές αντιμετώπισης των εχθρικών συμπεριφορών και της παρενόχλησης, που είναι κυρίως η συζήτηση με άλλους συναδέλφους για υποστήριξη και ιδέες και η αποφυγή ή η αντιμετώπιση των θυτών. Τα ευρήματα της παρούσας εργασίας μπορούν να παρέχουν χρήσιμη πληροφόρηση σε σχετικούς τομείς διαμόρφωσης πολιτικής για την ενίσχυση και υποστήριξη των εκπαιδευτικών ώστε να επιτελέσουν το έργο τους στο σχολείο και την κοινωνία.

Discovery prospects of a light Higgs boson at the LHC in type-I 2HDM

description: We present a comprehensive analysis of observing a light Higgs boson in the mass range $70$ -- $110$ GeV at the 13/14 TeV LHC, in the context of the type-I two-Higgs-doublet model. The decay of the light Higgs to a pair of bottom quarks is dominant in most parts of the parameter space, except in the fermiophobic limit. Here its decay to bosons, (mainly a pair of photons), becomes important. We perform an extensive collider analysis for the $b\bar{b}$ and $γγ$ final states. The light scalar is tagged in the highly boosted regimes for the $b \bar{b}$ mode to reduce the enormous QCD background. This decay can be observed with a few thousand fb$^{-1}$ of integrated luminosity at the LHC. Near the fermiophobic limit, the decay of the light Higgs to a pair of photons can even be probed with a few hundred fb$^{-1}$ of integrated luminosity at the LHC.

description: In this paper, we extend Lotay-Wei's Shi-type estimate from Laplacian flow to more general flows of G$_2$ structures including the modified Laplacian co-flow. Then we prove a version of $κ$-non-collapsing theorem. We will use both of them to study finite time singularities of general flows of G$_2$ structures.
