description: Two of my collaborations with Max Kreuzer involved classification problems related to string vacua. In 1992 we found all 10,839 classes of polynomials that lead to Landau-Ginzburg models with c=9 (Klemm and Schimmrigk also did this); 7,555 of them are related to Calabi-Yau hypersurfaces. Later we found all 473,800,776 reflexive polytopes in four dimensions; these give rise to Calabi-Yau hypersurfaces in toric varieties. The missing piece - toric constructions that need not be hypersurfaces - are the reflexive Gorenstein cones introduced by Batyrev and Borisov. I explain what they are, how they define the data for Witten's gauged linear sigma model, and how one can modify our classification ideas to apply to them. I also present results on the first and possibly most interesting step, the classification of certain basic weights systems, and discuss limitations to a complete classification.

description: We use the Bogoliubov-de Gennes formalism to analyze harmonically trapped Fermi gases with Rashba-type spin-orbit coupling in two dimensions. We consider both population-balanced and -imbalanced Fermi gases throughout the BCS-BEC evolution, and study the effects of spin-orbit coupling on the spontaneously induced countercirculating mass currents and the associated intrinsic angular momentum. In particular, we find that even a small spin-orbit coupling destabilizes Fulde-Ferrel-Larkin-Ovchinnikov (FFLO)-type spatially modulated superfluid phases as well as the phase-separated states against the polarized superfluid phase. We also show that the continuum of quasiparticle and quasihole excitation spectrum can be connected by zero, one or two discrete branches of interface modes, depending on the number of interfaces between a topologically trivial phase (e.g. locally unpolarized/low-polarized superfluid or spin-polarized normal) and a topologically nontrivial one (e.g. locally high-polarized superfluid) that may be present in a trapped system.

description: As a consequence of global interaction, real time news availability, consumer generated media and content, countries have become increasingly aware of their image domestically and internationally. In response to this awareness, some countries have adopted advertising and marketing practices to manage their country image. The current study aims to develop and test a theoretical model of nation branding, which integrates the concepts of the branding and nation images. It is proposed that the overall image of the country (i.e., nation brand) is a mediator between its brand assets (i.e., internal and external assets) and tourists’ future behaviors (i.e., intentions to visit). The contribution of this paper is that, put the nation brand for the first time as a mediator role in this paper. The results confirmed that nation brand is influenced by two types of brand assets and is a critical mediator between brand assets and intention to visit.

description: This paper creates a conceptual frame and explanatory point of reference for the collection of papers presented at the exploratory workshop “Data Science for Digital Art History: Tackling Big Data Challenges, Algorithms, and Systems” organized at the KDD 2018 Conference in Data Mining and Knowledge Discovery held in London in August 2018. The goal of the workshop was to probe the field and to build a constructive interdisciplinary dialogue between two research areas: Data Science and Art History. The workshop’s chairs and the authors of this paper share the conviction that Data Science can enrich art studies while analysis of visual data can have a positive impact on Data Science. Thus, the research initiative tried to critically reflect on the interdisciplinary collaboration between diverse research communities and its epistemological and ontological effects.

Year: 2012
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: A novel method to infer logical relationships between sets is presented. These sets can be any collection of elements, for example astronomical catalogs of celestial objects. The method does not require the contents of the sets to be known explicitly. It combines incomplete knowledge about the relationships between sets to infer a priori unknown relationships. Relationships between sets are represented by sets of Boolean hypercubes. This leads to deductive reasoning by application of logical operators to these sets of hypercubes. A pseudocode for an efficient implementation is described. The method is used in the Astro-WISE information system to infer relationships between catalogs of astronomical objects. These catalogs can be very large and, more importantly, their contents do not have to be available at all times. Science products are stored in Astro-WISE with references to other science products from which they are derived, or their dependencies. This creates full data lineage that links every science product all the way back to the raw data. Catalogs are created in a way that maximizes knowledge about their relationship with their dependencies. The presented algorithm is used to determine which objects a catalog represents by leveraging this information.

description: Building national brand plays an important role on today's economy to attract interested tourists in visiting various countries. There are different factors impacting national brand such as advertisement, natural attraction, etc. In this paper, we perform an empirical investigation to find the impact of ten most important factors on building brand. The study designs and distributes a questionnaire among 384 international tourists who visited Iran during the year of 2010 and it uses factor analysis to group important factors. The results extract four groups; the first factor includes three most important components including satellite advertisement programs, public awareness on economic power and public awareness on specialized symposium and conferences. The second factor includes three other important factors, which are public awareness on human right, advertisement programs through distribution brushers and internet advertisement. The third factor includes two variables, which are public awareness on education and access to educational services and introducing cultural heritage. Finally, the last factor includes introducing natural attraction and advertisement programs through distribution brushers.

description: Homoclinic classes of generic $C^1$-diffeomorphisms are maximal transitive sets and pairwise disjoint. We here present a model explaining how two different homoclinic classes may intersect, failing to be disjoint. For that we construct a one-parameter family of diffeomorphisms $(g_s)_{s\in [-1,1]}$ with hyperbolic points $P$ and $Q$ having nontrivial homoclinic classes, such that, for $s>0$, the classes of $P$ and $Q$ are disjoint, for $s<0$, they are equal, and, for $s=0$, their intersection is a saddle-node.

description: We report the discovery of Balmer broad absorption lines (BALs) in the quasar LBQS 1206+1052 and present a detailed analysis of the peculiar absorption line spectrum. Besides Mg II $λλ2796, 2803$ doublet, BALs are also detected in He I* multiplet at $λλ2946, 3189, 3889$ Åarising from metastable helium $2^3S$ level, and in H$α$ and H$β$ from excited hydrogen H I* $n=2$ level, which are rarely seen in quasar spectra. We identify two components in the BAL troughs of $Δv\sim$2000 km s$^{-1}$ width: One component shows an identical profile in H I*, \hei* and \mgii with its centroid blueshifted by $-v_{\rm c}\approx 726$ km\ s$^{-1}$. The other component is detected in \hei* and \mgii with $-v_{\rm c}\approx 1412$ km s$^{-1}$. We estimate the column densities of H I*, He I*, and Mg II, and compare them with possible level population mechanisms. Our results favor the scenario that the Balmer BALs originate in a partially ionized region with a column density of $N_{\rm H}\sim 10^{21-22}$ cm$^{-2}$ for an electron density of $n_e\sim 10^{6-8} $cm$^{-3}$ via Ly$α$ resonant scattering pumping. The harsh conditions needed may help to explain the rarity of Balmer absorption line systems in quasar spectra. With an $i$-band PSF magnitude of 16.50, LBQS 1206+1052 is the brightest Balmer-BAL quasar ever reported. Its high brightness and unique spectral properties make LBQS 1206+1052 a promising candidate for follow-up high-resolution spectroscopy, multi-band observations, and long-term monitoring.

description: We develop a theoretical framework to study slowly rotating compact stars in a rather general class of alternative theories of gravity, with the ultimate goal of investigating constraints on alternative theories from electromagnetic and gravitational-wave observations of compact stars. Our Lagrangian includes as special cases scalar-tensor theories (and indirectly f(R) theories) as well as models with a scalar field coupled to quadratic curvature invariants. As a first application of the formalism, we discuss (for the first time in the literature) compact stars in Einstein-Dilaton-Gauss-Bonnet gravity. We show that compact objects with central densities typical of neutron stars cannot exist for certain values of the coupling constants of the theory. In fact, the existence and stability of compact stars sets more stringent constraints on the theory than the existence of black hole solutions. This work is a first step in a program to systematically rule out (possibly using Bayesian model selection) theories that are incompatible with astrophysical observations of compact stars.

Coordination in space and time of excitatory and inhibitory synaptic plasticity at dendritic synapses
Creators: name: RUBEN, MASSIMO
Publisher: name: Universit� degli studi di Genova
Year: 2021

description: For years, GABAergic synapses were considered poorly plastic. However, an increasing body of evidence demonstrated that, similarly to excitatory synapses, inhibitory synapses formed by interneurons onto pyramidal cells can be modulated in response to neuronal activity. The spiking output of a neuron is determined by the opposite but concomitant action of excitation and inhibition. In this view, it is crucial to understand how plasticity at excitatory and inhibitory synapses is coordinated. In this thesis, I will describe two different types of plasticity interplay between excitation and inhibition, in space and time domains. In our previous work (Petrini et al., 2014) we characterized the induction and the expression of postsynaptic inhibitory long term potentiation (iLTP) following the administration of NMDA and CNQX (chemical protocol of induction of iLTP). Here we induced postsynaptic iLTP by administering electrophysiological stimulations intended to better mimic physiological neuronal activity. We observed that the delivery to the postsynaptic neuron of a train of action potentials at frequency of 2Hz, (that we define here low frequency stimulation, LFS) potentiated the amplitude of the inhibitory postsynaptic currents (iPSCs) up to 30 minutes. This particular form of iLTP depended on moderate calcium increase in the postsynaptic neuron and the activation of the Calcium calmodulin kinase II (CaMKII). The concomitant investigation of excitatory transmission revealed the depression of excitatory postsynaptic currents (ePSCs) amplitude thus indicating that LFS induced excitatory (LTD). In order to further study the interaction between excitatory and inhibitory synaptic plasticity, we paired the protocol of iLTP together with simultaneous photorelease of glutamate on a single spine. This particular type of Hebbian stimulation induced LTP at the photostimulated spine (Lee et al., 2009; Matsuzaki et al., 2001, 2004) and LTD on the other spines. In contrast, we observed that the GABAergic synapses located distant from the potentiated spine showed an iLTP while the ones located in a range of 3 micron from the potentiated spine were depressed. Such ?inversion of plasticity? was promoted by a massive influx of calcium and the activation of calpain, a protease involved in the cleavage of the gephyrin.
In the second part of this thesis, I will show a new type of structural inhibitory short term depression plasticity (siSTD) that occurs during the induction of the plasticity protocol, before the expression of iLTP. In particular, the depolarization of the postsynaptic neuron induced a transient depression of inhibitory synapses that was dependent on the fast activation of the protease calpain. We propose that such ?early? calpain activation pathway competes with that of the CaMKII thus defining the extent of long-term inhibitory plasticity.

description: Research relies on software and data – but how do we learn the skills to make use of them? Research Software Engineering is developing as a profession, working as part of the research team to improve the software used in research. They enable good practices in research software and thus make research more open and efficient. Despite the importance of Research Software Engineers, the majority of the existing RSE community are self-taught. There is a gap in professional education and cohort network for RSEs: even more so for those specialising in High Performance Computing.

UNIVERSE-HPC or ‘Understanding and Nurturing an Integrated Vision for Education in RSE and HPC’ has been exploring the different ways in which people from a wide diversity of disciplines and backgrounds can be helped to obtain the skills and experience they require to have a successful RSE career. This talk will introduce some of the that we have developed, from facilitating personal learning pathways and curriculum development, to flexible training platforms and course delivery choices, to building an engaged community of practitioners. Although UNIVERSE-HPC is finishing, this work is being continued through projects such as CHARTED and DRIFT, as well as through international initiatives.

This will provide clear routes to enable more people from a wide diversity of disciplines and backgrounds to obtain the skills and experience they require to have a successful RSE career: working within centres of excellence, RSE groups, and embedded in research groups.

This talk was presented at the UNIVERSE-HPC event "HPC-Ready: Developing RSE and HPC skills".in Edinburgh on 27 Mach 2025

description: We report unusual jamming in driven ordered vortex flow in 2H-NbS2. Reinitiating movement in these jammed vortices with a higher driving force, and halting it thereafter once again with a reduction in drive, unfolds a critical behavior centered around the de-pinning threshold via divergences in the lifetimes of transient states, validating the predictions of a recent simulation study, which also pointed out a correspondence between plastic de-pinning in vortex matter and the notion of random organization proposed in the context of sheared colloids undergoing diffusive motion.

description: The holographic bound asserts that the entropy $S$ of a system is bounded from above by a quarter of the area ${\cal A}$ of a circumscribing surface measured in Planck areas: $S\leq {\cal A}/4{\ell^2_P}$. This bound is widely regarded a desideratum of any fundamental theory. Moreover, it was argued that the holographic bound is necessary for the validity of the generalized second law (GSL) of thermodynamics. However, in this work we explicitly show that hyperentropic systems (those violating the holographic entropy bound) do exist in higher-dimensional spacetimes. We resolve this apparent violation of the GSL and derive an upper bound on the area of hyperentropic objects.

description: First-generation somatostatin receptor ligands (fg-SRLs), such as octreotide (OCT), represent the first-line medical therapy in acromegaly. Fg-SRLs show a preferential binding affinity for somatostatin receptor subtype-2 (SST2), while the second-generation ligand, pasireotide (PAS), has high affinity for multiple SSTs (SST5 > SST2 > SST3 > SST1). Whether PAS acts via SST2 in somatotroph tumors, or through other SSTs (e.g., SST5), is a matter of debate. In this light, the combined treatment OCT+PAS could result in additive/synergistic effects. We evaluated the efficacy of OCT and PAS (alone and in combination) on growth hormone (GH) secretion in primary cultures from human somatotroph tumors, as well as on cell proliferation, intracellular signaling and receptor trafficking in the rat GH4C1 cell line. The results confirmed the superimposable efficacy of OCT and PAS in reducing GH secretion (primary cultures), cell proliferation, cAMP accumulation and intracellular [Ca2+] increase (GH4C1 cells), without any additive effect observed for OCT+PAS. In GH4C1 cells, co-incubation with a SST2-selective antagonist reversed the inhibitory effect of OCT and PAS on cell proliferation and cAMP accumulation, while both compounds resulted in a robust internalization of SST2 (but not SST5). In conclusion, OCT and PAS seem to act mainly through SST2 in somatotroph tumor cells in vitro, without inducing any additive/synergistic effect when tested in combination.

description: Background: Post-traumatic stress disorder (PTSD) is prevalent in youngsters, teenagers, and grown-ups. It can happen alone or in comorbidity with different disarranges. A wide scope of psychotherapies, for example, hypnosis and cognitive-behavioral therapy (CBT) has been produced for PTSD treatment. Objectives: In this study, we compare the effectiveness of hypnosis and cognitive-behavioral therapy in reducing post-traumatic stress disorder. Methods: This research is done in the form of an experimental method. The research design is pre-test - post-test with a control group. The target population in this study consisted of 370 war veterans. The sample of the study consisted of 191 people who were randomly selected and answered the PTSD Checklist (PCL). Of the 86 respondents who achieved the highest score from the PCL questionnaire, 60 were randomly selected and divided into two experimental and one control group. One of the experimental groups; received 8 sessions of the CBT treatment and, the other group received 8 sessions Hypnosisand and the control group continued their usual treatment. After the treatment sessions, post-test was taken from all participants. Data were analyzed by using ANCOVA in SPSS version 21. Results: The results showed that there is a significant difference between the Hypnosis and CBT groups (P <0.01). There was also a significant difference between the control and the CBT groups as well as hypnosis (P <0.01). Conclusions The aftereffects of the current examination indicated that hypnosis and cognitive behavioral therapy are successful in decreasing post-traumatic stress disorder. We additionally found that hypnosis is more effective than CBT.
The Effect of Charge Order on the Plasmon Dispersion in Transition-Metal Dichalcogenides

description: We investigate the dispersion of the charge carrier plasmon in the three prototypical charge-density wave bearing transition-metal dichalcogenides 2H-TaSe2, 2H-TaS2 and 2H-NbSe2 employing electron energy-loss spectroscopy. For all three compounds the plasmon dispersion is found to be negative for small momentum transfers. This is in contrast to the generic behavior observed in simple metals as well as the related system 2H-NbS2, which does not exhibit charge order. We present a semiclassical Ginzburg-Landau model which accounts for these observations, and argue that the vicinity to a charge ordered state is thus reflected in the properties of the collective excitations.

Development of synthesis strategies for efficient, robust, and stable light - emitting nanocomposites based on halide perovskites

description: Over the past few years, halide perovskites have generated extensive interest as potential materials for various applications, such as light-emitting diodes, displays, detectors, and tracking (e.g., bio-applications or oil tracing). However, the effective implementation of these halide perovskite NCs in industrial manufacturing processes is limited by their poor stability under various conditions: when exposed to humidity, high temperature, and photo-irradiation, the NCs quickly degrade. Therefore, the research work included in this thesis is mainly focused on developing various strategies to improve the stability of halide perovskite NCs with the aim of implementing them in practical applications. Among different matrix encapsulation materials for perovskites (such as polymers, inorganic metal oxide/halides, and metal-organic framework), silica has been chosen as an efficient matrix to protect halide perovskite NCs due to its excellent properties, which include high optical transparency in the visible, chemical stability, abundance, non-toxicity, and low-cost. Two novel approaches to produce CsPbX3 NCs embedded in silica are developed as simple and straightforward methods via sol-gel route and molten salt synthesis. The resulting composites are investigated on structure, optical properties and their stability against environment conditions. As a proof of concept, these composites are also tested in some application such as down-converter phosphors in light-emitting diode and tracer in oil industry. In an addition work, the structure and optical properties of Sn-based perovskite materials, which are synthesized by hot-injection method, are also discussed, extending the scope of this thesis to non-toxic lead-free perovskite materials.

description: We report the discovery of 6 SX Phoenicis stars in the southern globular cluster NGC 4833. Images were obtained from January through June 2011 with the Southeastern Association for Research in Astronomy 0.6 meter telescope located at Cerro Tololo Interamerican Observatory. The image subtraction method of Alard & Lupton (1998)was used to search for variable stars in the cluster. We confirmed 17 previously cataloged variables by Demers & Wehlau(1977). In addition to the previously known variables we have identified 10 new variables. Of the total number of confirmed variables in our 10x10 arcmin^2 field, we classified 10 RRab variables, with a mean period of 0.69591 days, 7 RRc, with a mean period of 0.39555 days, 2 possible RRe variables with a mean period of 0.30950 days, a W Ursae Majoris contact binary, an Algol-type binary, and the 6 SX Phoenicis stars with a mean period of 0.05847 days. The periods, relative numbers of RRab and RRc variables, and Bailey diagram are indicative of the cluster being of the Oosterhoff type II. We present the phased-light curves, periods of previously known variables and the periods and classifications of the newly discovered variables, and their location on the color-magnitude diagram.

description: Polaris is one of the most observed stars in the night sky, with recorded observations spanning more than 200 years. From these observations, one can study the real-time evolution of Polaris via the secular rate of change of the pulsation period. However, the measurements of the rate of period change do not agree with predictions from state-of-the-art stellar evolution models. We show that this may imply that Polaris is currently losing mass at a rate of $\dot{M} \approx 10^{-6} M_\odot$ yr$^{-1}$ based on the difference between modeled and observed rates of period change, consistent with pulsation-enhanced Cepheid mass loss. A relation between the rate of period change and mass loss has important implications for understanding stellar evolution and pulsation, and provides insight into the current Cepheid mass discrepancy.

description: We use the Gutzwiller variational theory to calculate the ground-state phase diagram and quasi-particle bands of LaOFeAs. The Fe3d--As4p Wannier-orbital basis obtained from density-functional theory defines the band part of our eight-band Hubbard model. The full atomic interaction between the electrons in the iron orbitals is parameterized by the Hubbard interaction U and an average Hund's-rule interaction J. We reproduce the experimentally observed small ordered magnetic moment over a large region of (U,J) parameter space. The magnetically ordered phase is a stripe spin-density wave of quasi-particles.
