description: Genus Microselia Schmitz
 Microselia Schmitz, 1934: 11. Type-species: M. rivierae Schmitz, 1934.
 Recognition. Specimens of this genus, including this specimen, key correctly in Disney’s (1994) key to genera (females) to couplet 207, where the choices are Epacteon Borgmeier and Microselia Schmitz.
 The placement of this specimen in Microselia, and not Epacteon, is based on the third antennal segment being bean-shaped with a dorsal, pre-apical, arista and with the conus of the second antennal segment being inserted into the base of segment in normal way. Epacteon specimens have a pear-shaped third antennal segment, with an apical arista and with the conus of second segment inserted into the side, and not the base, of the third antennal segment.
 Most species of Microselia are described from females only. Phoridae genera are often known only from the morphology of specimens of one sex.
 High variability of characters for Microselia has been noted in the literature: absence, presence of vein 2 (Disney & Shaw, 1994; Carles-Tolra, 2006); absence, presence of supra-antennal bristles and the variable configuration of last tarsal segment of the foreleg (Disney, 1991) which is particularly relevant and morphologically similar to this specimen.
 Based on existing definitions of Phoridae genera, and with the understanding that Microselia is closely related to Pseudacteon (Delage et Lauraire, 1971; Disney, 1988, 1994), and Epacteon is perhaps a synonym of Microselia (Brian Brown, personal communication), the authors place this species in Microselia as identified by the world key to genera of female Phoridae (Disney, 1994).

description: The mortality of pancreatic cancer in China showed an increasing trend between 2005 and 2020, with significant discrepancies in the burden of pancreatic cancer in provinces. We analyzed numbers of death, incidence, disability-adjusted life years (DALY) and corresponding age-standardized rates for pancreatic cancer in China using data from the Global Burden of Disease Study 2021. We conducted trend analysis in pancreatic cancer burden over time by age group and gender. Decomposition analysis was used to assess the drivers of change in cancer-related deaths in China due to three explanatory factors: population growth, population ageing and age-specific mortality. In 2021, the ASMR of pancreatic cancer in China was 5.72/100,000(95%UI: 4.59, 6.91), the age-standardized incidence (ASIR) rate was 5.64/100,000(95%UI: 4.52, 6.84) and the age-standardized DALY rate was 137.23/100,000 (95%UI:108.15, 166.74). From 1990 to 2021, the ASMR of pancreatic cancer in China generally showed an increasing trend (AAPC: 0.56, 95%UI: 0.52, 0.59). The burden of pancreatic cancer was consistently higher in Chinese men compared to women during the study period.Compared with 1990, the number of deaths from pancreatic cancer has increased in all provinces of China in 2021, with the overall number of deaths increasing by 67.49%. Population ageing was the major cause of the increase in deaths from pancreatic cancer in China, accounting for 45.89%. The burden of pancreatic cancer in China is still at a high level and population ageing is the main reason for the increase in pancreatic cancer deaths.
Kinder, Küche, Kreativatelier! Alleinerziehende Sozialhilfebezügerinnen im Spannungsfeld zwischen Erziehungspflichten, Hausarbeit und Arbeitsintegration: Eine empirische Untersu-chung über die Praxis der Sozialdienste im Berner Oberland.

description: Alleinerziehende sind stark gefährdet, durch die Sozialdienste unterstützt werden zu müssen. So beziehen rund 21% von ihnen Sozialhilfe und sind dadurch angehalten, neben der Erziehung der Kinder und der Führung des Haushaltes auch einer Erwerbstätigkeit nachzugehen oder an einer Integrationsmassnahme teilzunehmen. Diese Masterarbeit geht der Frage nach, wie sich die Arbeitsintegration der alleinerziehenden Sozialhilfebezügerinnen im Berner Oberland gestaltet und welche Faktoren eine berufliche Integration fördern oder hindern. Insbesondere steht die Richtlinie der Schweizerischen Konferenz für Sozialhilfe (SKOS) im Mittelpunkt, welche besagt, dass spätestens nach dem voll- endeten ersten Lebensjahr des Kindes eine Erwerbstätigkeit oder eine Teilnahme an einer Integrationsmassnahme erwartet wird. In einer empirischen Untersuchung wurden die Sozial- arbeitenden, welche im Berner Oberland für die Auszahlung der Sozialhilfe zuständig sind, online befragt. Die Ergebnisse geben Antworten darauf, wie diese Richtlinie umgesetzt wird und welche Aspekte eine Arbeitsintegration unterstützen oder erschweren. Auch beantwortet diese Masterarbeit die Frage, welche beruflichen Integrationsangebote im Berner Oberland alleinerziehenden Sozialhilfebezügerinnen zur Verfügung stehen und wie sie von dieser Personengruppe genutzt werden. Sowohl die theoretische Auseinandersetzung mit der Thematik wie auch die empirische Untersuchung zeigen auf, welchen Erschwernissen alleinerziehende Sozialhilfebezügerinnen in der beruflichen Integration begegnen. Hierbei sind auf der individuellen, institutionellen und strukturellen Ebene Schwierigkeiten auszumachen, auf welche vertiefter eingegangen wird. Diese Masterarbeit zeigt jedoch auch zukunftsorientierte Handlungsmöglichkeiten auf, wie diese Umstände verbessert und umgestaltet werden können und welche Optionen die Praxis hat, die Arbeitsintegration für alleinerziehende Sozialhilfebezügerinnen besser gestalten zu können.

description: We conjecture a geometrical form of the Paley-Wiener theorem for the Dunkl transform and prove three instances thereof, one of which involves a limit transition from Opdam's results for the graded Hecke algebra. Furthermore, the connection between Dunkl operators and the Cartan motion group is established. It is shown how the algebra of radial parts of invariant differential operators can be described explicitly in terms of Dunkl operators, which implies that the generalized Bessel functions coincide with the spherical functions. In this context, the restriction of Dunkl's intertwining operator to the invariants can be interpreted in terms of the Abel transform. Using shift operators we also show that, for certain values of the multiplicities of the restricted roots, the Abel transform is essentially inverted by a differential operator.

The sizes of Ultra Massive Galaxies as probes of the galaxy-halo connection - the role of the Nancy Grace Roman Space Telescope
Creators: name: Zanisi, Lorenzo
Publisher: name: Zenodo
Year: 2021

description: The formation of Ultra Massive Galaxies (UMGs, Mstar>10^11.2 Msun) is debated. The physical sizes of UMGs are an important probe of possible formation scenarios for these galaxies. In this theoretical work we investigate the evolution of the size distributions of UMGs, which has been little explored so far at high redshift, but that will become available with the wide coverage area offered by the Roman Telescope. To do so, we adopt a semi-empirical approach based on the stellar mass-halo mass (SMHM) relation and the galaxy size-halo size (GSHS) relation. The GSHS is sufficient to broadly reproduce the mean size evolution of UMGs out to z~3. We also show that the predicted evolution of the number density of compact UMGs implied by a tight GSHS (supported by low z data) agrees with formation scenarios where the late evolution of UMGs is dominated by the growth of individual galaxies, while at high redshift most UMGs build up in a compact phase, which supports a progenitor bias scenario at early epochs. The GSHS relation can make explicit predictions on environmental trends of galaxy sizes as well as on the number density of compact relics which survived as satellites. The predictions significantly depend on the SMHM relation - possibly a consequence of the different contributions from in-situ and ex-situ processes implied by different physical models. Thus, the large sample of UMGs observed by Roman Telescope will help constrain the galaxy-halo connection and galaxy evolution.

description: We implement Mikhailov's holomorphic curve construction to explore various properties of giant gravitons in type IIB string theory on $AdS_{5}\times T^{1,1}$. By coloring the D-brane worldvolume, we are able to show how, in the string theory, the giant graviton factorizes at its maximal size into two dibaryons - topologically stable D-branes wrapping non-contractible cycles in the $T^{1,1}$. This is related to the structure of the symmetry group of the emergent Klebanov-Witten gauge theory being a product - $SU(N) \times SU(N)$ instead of the canonical $SU(N)$. Finally, we complete this study with a systematic and detailed construction of the spectrum of small fluctuations about the giant graviton configuration. Curiously, we find that the fluctuation spectrum depends on the size of the giant. The similarity of the operator structures in the Klebanov-Witten and ABJM theories leads us to believe that the D4-brane giant graviton in type IIA string theory on $AdS_{4}\times \mathbb{CP}^{3}$ factorizes into two $\mathbb{CP}^{2}$ dibaryons in a qualitatively similar way.

description: Mid infrared integrated quantum photonics is a promising platform for applications in sensing and metrology. However, there are only few examples of on-chip single photon sources at these wavelengths. These have limited performances with respect to their C-band counterparts. In this work, we demonstrate a new approach to generate heralded single photons in the mid infrared on a silicon chip. By using a standard C-band pump, the inter-modal spontaneous four wave mixing enables the generation of the herald idler at 1259.7 nm and the heralded signal at 2015 nm. The idler photon is easily detected with a common infrared single photon detector while the signal photon is upconverted to the visible before its detection. In this way, we are able to operate a mid infrared source without the need of mid infrared detectors and laser sources. By measuring a heralded $g^{(2)}$ of $0.23 \, \pm \, 0.08$ we demonstrate the single photon behaviour of the source as well as the feasibility of multi-photon coincidence measurements beyond 2 $μ$m with our setup. The source exhibits a high intrinsic heralding efficiency of $(59 \, \pm \,5)\%$, a maximum coincidence to accidental ratio of $40.4 \, \pm \, 0.9$ and a generation probability of $\left( 0.72 \, \pm \, 0.10 \right)$ W$^{-2}$.

Pegasus company. The self-management cooperative tackling job insecurity
Creators: name: Martinelli, Francesca
Publisher: name: Zenodo
Year: 2022

description: The COVID-19 pandemic showed the essential role of social protection in the current context, and the relative difficulties of the “grey zone” workers who usually do not receive health insurance, pension, family and sick leave, and unemployment benefits. This paper brings the case of self-management cooperatives and studies their role in addressing this situation in Europe. Self-management cooperatives are an attempt by workers isolated in the labour market to find an alternative to the business logic of individualisation and competition in favour of peer-to-peer exchange and democratic, collective working practices. Through the self- management cooperatives workers self-organise to obtain better working conditions and access to social protections. From the 11 case studies it emerges that the model of the self- management cooperative can be an important tool to regain control over work, through the re- appropriation of one’s own work dynamics, means of production and “voice”.
Full versus quasi-particle self consistency in vertex corrected GW approaches

description: Using seven semiconductors/insulators with band gaps covering the range from 1 eV to 10 eV we systematically explore the performance of two different variants of self-consistency associated with famous Hedin's system of equations: the full self-consistency and the so called quasi-particle approximation to it. The pros and cons of these two variants of self-consistency are sufficiently well documented in literature for the simplest GW approximation to the Hedin's equations. Our study, therefore, aims primarily at the level of theory beyond GW approximation, i.e. at the level of theory which includes vertex corrections. Whereas quasi-particle self-consistency has certain advantages at GW level (well known fact), the situation becomes quite different when vertex corrections are included. In the variant with full self-consistency, vertex corrections (both for polarizability and for self energy) systematically reduce the calculated band gaps making them closer to the experimental values. In the variant with quasi-particle self-consistency, however, an inclusion of the same diagrams has considerably larger effect and calculated band gaps become severely underestimated. Different effect of vertex corrections in two variants of self-consistency can be related to the Z-factor cancellation which plays positive role in quasi-particle self-consistency at GW level of theory but appears to be destructive for the quasi-particle approximation when higher order diagrams are included. Second result of our study is that we were able to reproduce the results obtained with the Questaal code using our FlapwMBPT code when the same variant of self-consistency (quasi-particle) and the same level of vertex corrections (for polarizability only, static approximation for screened interaction, and Tamm-Dancoff approximation for the Bethe-Salpeter equation) are used.

description: The rotation curve, the total mass and the gravitational potential of the Galaxy are sensitive measurements of the dark matter halo profile. In this publication cuspy and cored DM halo profiles are analysed with respect to recent astronomical constraints in order to constrain the shape of the Galactic DM halo and the local DM density. All Galactic density components (luminous matter and DM) are parametrized. Then the total density distribution is constrained by astronomical observations: 1) the total mass of the Galaxy, 2) the total matter density at the position of the Sun, 3) the surface density of the visible matter, 4) the surface density of the total matter in the vicinity of the Sun, 5) the rotation speed of the Sun and 6) the shape of the velocity distribution within and above the Galactic disc. The mass model of the Galaxy is mainly constrained by the local matter density (Oort limit), the rotation speed of the Sun and the total mass of the Galaxy from tracer stars in the halo. It is shown from a statistical chi^2 fit to all data that the local DM density is strongly positively (negatively) correlated with the scale length of the DM halo (baryonic disc). Since these scale lengths are poorly constrained the local DM density can vary from 0.2 to 0.4 GeV/cm^3 (0.005 - 0.01 M_sun/pc^3) for a spherical DM halo profile and allowing total Galaxy masses up to 2 * 10^12 M_sun. For oblate DM halos and dark matter discs, as predicted in recent N-body simulations, the local DM density can be increased significantly.

description: HPC is an enabling platform for AI. The introduction of AI workloads in the HPC applications basket has non-trivial consequences both on the way of designing AI applications and on the way of providing HPC computing. This is the leitmotif of the convergence between HPC and AI. The formalized definition of AI pipelines is one of the milestones of HPC-AI convergence. If well conducted, it allows, on the one hand, to obtain portable and scalable applications. On the other hand, it is crucial for the reproducibility of scientific pipelines. In this work, we advocate the StreamFlow Workflow Management System as a crucial ingredient to define a parametric pipeline, called "CLAIRE COVID-19 Universal Pipeline," which is able to explore the optimization space of methods to classify COVID-19 lung lesions from CT scans, compare them for accuracy, and therefore set a performance baseline. The universal pipeline automatizes the training of many different Deep Neural Networks (DNNs) and many different hyperparameters. It, therefore, requires a massive computing power, which is found in traditional HPC infrastructure thanks to the portability-by-design of pipelines designed with StreamFlow. Using the universal pipeline, we identified a DNN reaching over 90% accuracy in detecting COVID-19 lesions in CT scans.

description: In the complete graph on n vertices, when each edge has a weight which is an exponential random variable, Frieze proved that the minimum spanning tree has weight tending to zeta(3)=1/1^3+1/2^3+1/3^3+... as n goes to infinity. We consider spanning trees constrained to have depth bounded by k from a specified root. We prove that if k > log_2 log n+omega(1), where omega(1) is any function going to infinity with n, then the minimum bounded-depth spanning tree still has weight tending to zeta(3) as n -> infinity, and that if k < log_2 log n, then the weight is doubly-exponentially large in log_2 log n - k. It is NP-hard to find the minimum bounded-depth spanning tree, but when k < log_2 log n - omega(1), a simple greedy algorithm is asymptotically optimal, and when k > log_2 log n+omega(1), an algorithm which makes small changes to the minimum (unbounded depth) spanning tree is asymptotically optimal. We prove similar results for minimum bounded-depth Steiner trees, where the tree must connect a specified set of m vertices, and may or may not include other vertices. In particular, when m = const * n, if k > log_2 log n+omega(1), the minimum bounded-depth Steiner tree on the complete graph has asymptotically the same weight as the minimum Steiner tree, and if 1 <= k <= log_2 log n-omega(1), the weight tends to (1-2^{-k}) sqrt{8m/n} [sqrt{2mn}/2^k]^{1/(2^k-1)} in both expectation and probability. The same results hold for minimum bounded-diameter Steiner trees when the diameter bound is 2k; when the diameter bound is increased from 2k to 2k+1, the minimum Steiner tree weight is reduced by a factor of 2^{1/(2^k-1)}.

LE POUVOIR D'INJONCTION DU JUGE CONSTITUTIONNEL AU GABON : VERS UNE NOUVELLE ARCHITECTURE DE LA JUSTICE CONSTITUTIONNELLE  EN AFRIQUE
Creators: name: Dr NSE NSIH Elvye Naoline
Publisher: name: Zenodo
Year: 2025

description: Cet article explore le pouvoir d’injonction du juge constitutionnel au Gabon, dans un contexte où les mutations démocratiques africaines appellent une reconfiguration des fonctions juridictionnelles. Ce pouvoir, encore controversé, est d’autant plus crucial qu’il engage la Cour Constitutionnelle non seulement comme gardienne de la Constitution, mais aussi comme acteur dynamique dans la régulation de la vie politique. L’étude vise à justifier la nécessité d’un tel pouvoir face aux dysfonctionnements institutionnels observés, en particulier à travers l’analyse de la décision N°022/CC du 30 avril 2018. Par une approche essentiellement qualitative, basée sur l’analyse doctrinale, la jurisprudence constitutionnelle gabonaise et des modèles comparatifs africains (Bénin, Sénégal), l’étude met en évidence les fondements juridiques, les limites et les implications d’un tel pouvoir dans un État de droit. L’article conclut que l’injonction peut être un outil légitime du juge constitutionnel, à condition d’un encadrement strict garantissant le respect de la séparation des pouvoirs. Il en ressort une corrélation forte entre l’usage de ce pouvoir (coefficient conceptuel implicite ≈ 0,88) et l’amélioration du fonctionnement institutionnel, sans empiéter sur les prérogatives de l’exécutif. En conclusion, cette recherche recommande une réforme de la loi organique gabonaise pour préciser les cas d’usage de l’injonction, renforcer la formation des juges constitutionnels, et instaurer un mécanisme de suivi de l’exécution des décisions. Cela permettrait de faire du juge constitutionnel un contre-pouvoir effectif, garant de l’équilibre institutionnel dans une démocratie pluraliste.
I sensi spirituali nel Liber di Angela da Foligno. La metafora del "gusto" nel Liber di Angela da Foligno e nella mistica femminile francescana tra XIII e XIV secolo.

description: Angela da Foligno’s Liber is a fundamental text for the scholar of Women Mystics between the XIIIth and the XIVth century in Italy and all over Europe, and it has been chosen in my research because of its originality, with refer of its feminine and franciscan essence. Angela teaches to the italian hagiographic tradition the internal point of view of the holy woman, who becomes the teller of her both ordinary and extraordinary experiences.
After giving references about the religious and social historical universe in evolution during the XIIth century, my research proceeds with a linguistic and rhetorical analysis based upon the Liber. 
I have been searching in Angela’s text and in contemporary italian feminine hagiography the sensory metaphor of “tasting”. That kind of metaphor has an ancient memory and, thanks to the Origene’s studies - the Christian Father of the IIIrd century - we can easily recognize it already in the Bible; Origene identifies the sensory metaphor as a rhetoric system, able to exemplify the God learning process of soul. 
Theory of “spiritual senses”, theory of vision and rhetoric, evolving from the IIIrd to the XIIIth century, are the theological and linguistic heritage of our feminine and franciscan literature. Inside of that, the metaphor of “tasting” moves and changes, therefore becoming the favourite way of mystics to represent the contact of their souls with God.

description: In this paper we describe the commutant of an arbitrary subalgebra $A$ of the algebra of functions on a set $X$ in a crossed product of $A$ with the integers, where the latter act on $A$ by a composition automorphism defined via a bijection of $X$. The resulting conditions which are necessary and sufficient for $A$ to be maximal abelian in the crossed product are subsequently applied to situations where these conditions can be shown to be equivalent to a condition in topological dynamics. As a further step, using the Gelfand transform we obtain for a commutative completely regular semi-simple Banach algebra a topological dynamical condition on its character space which is equivalent to the algebra being maximal abelian in a crossed product with the integers.

description: The research is focused on the origin and the structure of the European party systems in long-standing democracies and in post-communist countries. Considering the differences between the western frozen party systems and the eastern unfrozen party systems, we propose a framework of analysis based on the theoretical and conceptual linkage between genetic approach and spatial theories of competition, identified in the normative component of a cleavage. At first, we propose some operational criteria to distinguish the dimensions of competition from the dimensions of identification through the use of the manifesto project surveys. Then, through the data of an expert survey and of some recent electoral mass surveys, we empirically test a set of propositions concerning, on the one hand, the congruence between party policy positions and party-voters policy positions and, on the other hand, the level of correlation between parties positions on different issue dimensions and their placement on the left-right axis.

description: The X-ray source 4U 1822-371 is an eclipsing low-mass X-ray binary and X-ray pulsar, hosting a NS that shows periodic pulsations in the X-ray band. The inclination angle of the system is so high that in principle, it should be hard to observe both the direct thermal emission of the central object and the reflection component of the spectrum because they are hidden by the outer edge of the accretion disc. Assuming that the source accretes at the Eddington limit, we analysed non-simultaneous XMM-Newton and NuSTAR observations and studied the average broadband spectrum, with the aim to investigate the presence of a reflection component. No such component has been observed before in a high-inclination source such as 4U 1822-371. We modelled the spectral emission of the source using two different reflection models, Diskline plus Pexriv and the self-consistent model RfxConv. In our analysis, we find significant evidence of a reflection component in the spectrum, in addition to two lines associated with neutral or mildly ionised iron. The continuum spectrum is well fitted by a saturated Comptonisation model and a thermal black-body component emitted by the accretion disc at a lower temperature. We updated the ephemeris, adding two new eclipse times to the most recent ephemeris reported in literature. In our proposed scenario, the source is accreting at the Eddington limit with an intrinsic luminosity of $10^{38}$ erg/s, while the observed luminosity is two orders of magnitude lower. Despite the high inclination, we find that a reflection component is required to fit residuals at the Fe line range and the hard excess observed in the spectrum. The best-fit value of the inner disc radius is still uncertain and model dependent. More observations are therefore needed to confirm these results, which can give important information on this enigmatic and peculiar source.

description: Considering an arbitrary, varying equation of the state parameter, the thermodynamic properties of the dark energy fluid in a semiclassical loop quantum cosmology scenario, which we consider the inverse volume modification, is studied. The equation of the state parameters are corrected as a semiclassical one during considering the effective behavior. Assuming that the apparent horizon has Hawking temperature, the modified entropy-area relation is obtained, we find that this relation is different from the one which is obtained by considering the holonomy correction. Considering the dark energy is a thermal equilibrium fluid, we get the expressions for modified temperature, chemical potential and entropy. The temperature, chemical potential and entropy are well-defined in the semiclassical regions.

description: We have studied the dark matter (DM) distribution in a approx 10^12 h^-1 M_sun mass halo extracted from a simulation consistent with the concordance cosmology, where the physics regulating the transformation of gas into stars was allowed to change producing galaxies with different morphologies. The presence of baryons produces the concentration of the DM halo with respect to its corresponding dissipationless run, but we found that this response does not only depend on the amount of baryons gathered in the central region but also on the way they have been assembled. DM and baryons affect each other in a complex way so the formation history of a galaxy plays an important role on its final total mass distribution. Supernova (SN) feedback regulates the star formation and triggers galactic outflows not only in the central galaxy but also in its satellites. Our results suggest that, as the effects of SN feedback get stronger, satellites get less massive and can even be more easily disrupted by dynamical friction, transferring less angular momentum. We found indications that this angular momentum could be acquired not only by the outer part of the DM halo but also by the inner ones and by the stellar component in the central galaxy. The latter effect produces stellar migration which contributes to change the inner potential well, probably working against further DM contraction. As a consequence of the action of these processes, when the halo hosts a galaxy with an important disc structure formed by smooth gas accretion, it is more concentrated than when it hosts a spheroidal system which experienced more massive mergers and interactions.

description: Starting with a complex commutative semi-simple regular Banach algebra $A$ and an automorphism $σ$ of $A$, we form the crossed product of $A$ with the integers, where the latter act on $A$ via iterations of $σ$. The automorphism induces a topological dynamical system on the character space $Δ(A)$ of $A$ in a natural way. We prove an equivalence between the property that every non-zero ideal in the crossed product has non-zero intersection with the subalgebra $A$, maximal commutativity of $A$ in the crossed product, and density of the non-periodic points of the induced system on the character space. We also prove that every non-trivial ideal in the crossed product always intersects the commutant of $A$ non-trivially. Furthermore, under the assumption that $A$ is unital and such that $Δ(A)$ consists of infinitely many points, we show equivalence between simplicity of the crossed product and minimality of the induced system, and between primeness of the crossed product and topological transitivity of the system.

description: Introduction Phospholipase Cb1 (PLC-β1) is a key player in the regulation of nuclear inositol lipid
signaling and of a wide range of cellular functions, such as proliferation and differentiation (1,2,3).
PLCb1 signaling depends on the cleavage of phosphatidylinositol 4,5-bisphosphate and the
formation of the second messengers diacylglycerol and Inositol tris-phosphate which activate
canonical protein kinase C (cPKC) isoforms. Here we describe a proteomic approach to find out a
potential effector of nuclear PLC-b1 dependent signaling during insulin stimulated myogenic
differentiation.
Methods Nuclear lysates obtained from insulin induced C2C12 myoblasts were
immunoprecipitated with anti-phospho-substrate cPKC antibody. Proteins, stained with Comassie
blue, were excised, digested and subsequently analysed in LC-MS/MS. For peptide sequence
searching, the mass spectra were processed and analyzed using the Mascot MS/MS ion search
program with the NCBI database. Western blotting, GST-pull down and co-immunoprecipitation
were performed to study the interaction between eEF1A2 and cPKCs. Site direct mutagenesis was
performed to confirm the phosphorylated motif recognized by the antibody. Immunofluorescence
analysis, GFP-tagged eEF1A2 vector and subcellular fractionation were performed to study nuclear
localization and relative distribution of eEF1A2.
Results We have previously shown that PLC-β1 is greatly increased at the nuclear level during
insulin-induced myoblasts differentiation and that this nuclear localization is essential for induction
of differentiation. Thus, nuclear proteins of insulin stimulated C2C12 myoblasts, were
immunoprecipitated with an anti-phospho-substrate cPKC antibody. After Electrophoretic gel
separation of proteins immunoprecipitated, several molecules were identified by LC-MS/MS.
Among these most relevant and unexpected was eukaryotic elongation factor 1 alpha 2 (eEF1A2).
We found that eEF1A2 is phosphorylated by PKCb1 and that these two molecules coimmunolocalized
at the nucleolar level. eEF1A2 could be phosphorylated in many sites among
which both threonine and serine residues. By site direct mutagenesis we demonstrated that it is the
serine residue of the motif recognized by the antibody that is specifically phosphorylated by
PKCb1. The silencing of PLCb1 gives rise to a reduction of expression and phosphorylation levels
of eEF1A2 indicating this molecule as a target of nuclear PLCb1 regulatory network during
myoblasts differentiation.

description: We consider the possibility of having Dark Matter (DM) black holes motivated by the Einasto density profile. This generalizes both the noncommutative mini black hole model and allows DM to enter as the matter constituent which makes up the black hole. We show that it is possible to construct a black hole solution for each value of the Einasto index and for different values of the mass parameter, provided that the we work with the energy-momentum tensor of an anisotropic fluid. In particular, we achieve that by first considering the equation of state (EOS) $p_r=-ρ$. It turns out that the corresponding black hole solution exhibits a horizon structure similar to that of a Reissner-Nordström black hole and the central singularity is replaced by a regular de Sitter core. We also show that if the previous EOS is replaced by a nonlocal one, it is possible to construct a self-gravitating fuzzy DM droplet but also in this case, the radial pressure is negative. Finally, we contemplate scenarios of different dark matter black holes with moderate mass values which could have formed in galaxies. In particular, we probe the possibility whether such black holes could also be the central galactic objects.

description: We observe the transient formation of a ringed pattern state during spin-up of an evaporating fluid on a time scale of order a few Ekman spin-up times. The ringed state is probed using infrared thermometry and particle image velocimetry and it is demonstrated to be a consequence of the transient balance between Coriolis and viscous forces which dominate inertia, each of which are extracted from the measured velocity field. The breakdown of the ringed state is quantified in terms of the antiphasing of these force components which drives a Kelvin-Helmholtz instability and we show that the resulting vortex grid spacing scales with the ring wavelength. This is the fundamental route to quasi-two dimensional turbulent vortex flow and thus may have implications in astrophysics and geophysics wherein rotating convection is ubiquitous. sics.

We examine various attributes of these pit structures in New Horizons data sets, revealing their length, aspect ratios, and orientation properties; we also study their interior reflectivities, colors, and compositions, and compare these attributes to some other relevant regions on Pluto. We then comment on origin mechanisms of the pits and also the fate of the missing volatiles represented by the pits on Sputnik Planitia.

description: In this thesis I have characterized the trace measures for particular potential spaces of functions defined on R^n, but "mollified" so that the potentials are de facto defined on the upper half-space of R^n. The potential functions are kind Riesz-Bessel. The characterization of trace measures for these spaces is a test condition on elementary sets of the upper half-space. To prove the test condition as sufficient condition for  trace measures, I had give an extension to the case of upper half-space of the Muckenhoupt-Wheeden and Wolff inequalities.  Finally I characterized the Carleson-trace measures for Besov spaces of discrete martingales. This is a simplified discrete model for harmonic extensions of Lipschitz-Besov spaces.
