description: Diagnostic categories do not completely reflect the heterogeneous expression of psychosis. Using data from the EU-GEI study, we evaluated the impact of schizophrenia polygenic risk score (SZ-PRS) and patterns of cannabis use on the transdiagnostic expression of psychosis. We analysed first-episode psychosis patients (FEP) and controls, generating transdiagnostic dimensions of psychotic symptoms and experiences using item response bi-factor modelling. Linear regression was used to test the associations between these dimensions and SZ-PRS, as well as the combined effect of SZ-PRS and cannabis use on the dimensions of positive psychotic symptoms and experiences. We found associations between SZ-PRS and (1) both negative (B = 0.18; 95%CI 0.03-0.33) and positive (B = 0.19; 95%CI 0.03-0.35) symptom dimensions in 617 FEP patients, regardless of their categorical diagnosis; and (2) all the psychotic experience dimensions in 979 controls. We did not observe associations between SZ-PRS and the general and affective dimensions in FEP. Daily and current cannabis use were associated with the positive dimensions in FEP (B = 0.31; 95%CI 0.11-0.52) and in controls (B = 0.26; 95%CI 0.06-0.46), over and above SZ-PRS. We provide evidence that genetic liability to schizophrenia and cannabis use map onto transdiagnostic symptom dimensions, supporting the validity and utility of the dimensional representation of psychosis. In our sample, genetic liability to schizophrenia correlated with more severe psychosis presentation, and cannabis use conferred risk to positive symptomatology beyond the genetic risk. Our findings support the hypothesis that psychotic experiences in the general population have similar genetic substrates as clinical disorders.
Comparative Assessment of Banana, Plantain and Cassava Peels as Potential Feedstock for Bioethanol Production

description: Biofuels derived from feedstocks like lignocellulosic biomass are excellent substitutes for fossil fuel as they are more environmentally advantaged and eco-friendly than fossil fuel. The high cost of biomass conversion to biofuel is the main factor impeding largescale biofuel production. This research project examined the production of biofuel from locally sourced materials obtained and processed at a very low cost. 40g of cassava, plantain (ripe and unripe), and banana (ripe and unripe) peels were pretreated using the physical method which involved shredding, grinding, and heating of substrates to increase the surface area for enzymatic action. Gloeophyllum Sepiarium (Polypore mushroom) and Pleurotus Ostreatus (Oyster mushroom) were used to hydrolyse the substrate at room temperature for 7 days. Saccharomyces Cerevisiae (Baker yeast) was further used to ferment the samples at room temperature for 7 days. The fermented samples were distilled at 78oC and the quantity of bioethanol produced was determined. After the hydrolysis process, the amount of sugar present in the samples was determined using the DNS reagent method. The highest yield of 0.8859g/L was obtained in cassava peels, followed by 0.7440g/L in unripe banana peels, and the least was obtained in ripe plantain peels with a yield of 0.5330g/L. During fermentation of the samples using saccharomyces cerevisiae, the quantity of reducing sugar present in the samples was determined at a 24-hour interval. The value obtained showed a steady decline in the quantity of reducing sugar present in the samples indicating the conversion of sugar to bioethanol. The quantity of bioethanol distilled from the samples was highest in cassava peels with a yield of 13.2cm3 and lowest in ripe plantain with a yield of 3.9cm3 . This research project revealed that the maximum yield of bioethanol can be obtained on a large scale from cassava peels using lowcost enzyme-producing organisms like mushrooms for hydrolysis

Downward-going tau neutrinos as a new prospect of detecting dark matter

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Dark matter trapped in the Sun produces a flux of all flavors of neutrinos, which then reach the Earth after propagating out of the Sun and oscillating from the production point to the detector. The typical signal which is looked at refers to the muon neutrino component and consists of a flux of up-going muons in a neutrino detector. We propose instead a novel signature: the possibility of looking at the tau neutrino component of the dark matter signal, which is almost background-free in the downward-going direction, since the tau neutrino amount in atmospheric neutrinos is negligible and in the down-going baseline atmospheric muon-neutrinos have no time to sizably oscillate. We analyze the prospects of studying the downward-going tau neutrinos from dark matter annihilation (or decay) in the Sun in Cherenkov detectors, by looking at hadronic showers produced in the charged-current tau neutrino interactions and subsequent tau decay. We discuss the various sources of background (namely the small tau neutrino component in atmospheric neutrinos, both from direct production and from oscillations; tau neutrinos from solar corona interactions; the galactic tau neutrino component) as well as sources of background due to misidentification of electron and muon events. We find that the downward-going tau neutrinos signal has potentially very good prospects for Mton scale Cherenkov detectors, the main limitation being the level of misidentification of non-tau events, which need to be kept at level of percent. Several tens of events per year (depending on the dark matter mass and annihilation/decay channel) are potentially collectible with a Mton scale detector, and a 5 sigma significance discovery is potentially reachable for dark matter masses in the range from 20 to 300 GeV with a few years of exposure on a Mton detector.

description: Glutamoptosis is the induction of apoptotic cell death as a consequence of the aberrant activation of glutaminolysis and mTORC1 signaling during nutritional imbalance in proliferating cells. The role of the bioenergetic sensor AMPK during glutamoptosis is not defined yet. Here, we show that AMPK reactivation blocks both the glutamine-dependent activation of mTORC1 and glutamoptosis in vitro and in vivo. We also show that glutamine is used for asparagine synthesis and the GABA shunt to produce ATP and to inhibit AMPK, independently of glutaminolysis. Overall, our results indicate that glutamine metabolism is connected with mTORC1 activation through two parallel pathways: an acute alpha-ketoglutarate-dependent pathway; and a secondary ATP/AMPK-dependent pathway. This dual metabolic connection between glutamine and mTORC1 must be considered for the future design of therapeutic strategies to prevent cell growth in diseases such as cancer.

description: Observations of disk galaxies at z~2 have demonstrated that turbulence driven by gravitational instability can dominate the energetics of the disk. We present a 1D simulation code, which we have made publicly available, that economically evolves these galaxies from z~2 to z~0 on a single CPU in a matter of minutes, tracking column density, metallicity, and velocity dispersions of gaseous and multiple stellar components. We include an H$_2$ regulated star formation law and the effects of stellar heating by transient spiral structure. We use this code to demonstrate a possible explanation for the existence of a thin and thick disk stellar population and the age-velocity dispersion correlation of stars in the solar neighborhood: the high velocity dispersion of gas in disks at z~2 decreases along with the cosmological accretion rate, while at lower redshift, the dynamically colder gas forms the low velocity dispersion stars of the thin disk.

description: Certain dark matter interactions with nuclei are mediated possibly by a scalar or pseudoscalar Higgs boson. The estimation of the corresponding cross sections requires a correct evaluation of the couplings between the scalar or pseudoscalar Higgs boson and the nucleons. Progress has been made in two aspects relevant to this study in the past few years. First, recent lattice calculations show that the strange-quark sigma term $σ_s$ and the strange-quark content in the nucleon are much smaller than what are expected previously. Second, lattice and model analyses imply sizable SU(3) breaking effects in the determination on the axial-vector coupling constant $g_A^8$ that in turn affect the extraction of the isosinglet coupling $g_A^0$ and the strange quark spin component $Δs$ from polarized deep inelastic scattering experiments. Based on these new developments, we re-evaluate the relevant nucleon matrix elements and compute the scalar and pseudoscalar couplings of the proton and neutron. We also find that the strange quark contribution in both types of couplings is smaller than previously thought.

Un'eco d'Oriente. Sekherezada di Rimskij-Korsakov

description: Oggi come in passato l'Oriente è vittima di stereotipi derivati dalla tradizione orientalistica ottocentesca che ha contribuito a plasmare una miriade di cliché esotici dai quali fatichiamo a renderci indipendenti. In questo intervento si cerca di segnalare, e in parte demitizzare, alcuni di tali luoghi comuni, con particolare riferimento al contesto musicale russo di fine Ottocento. Nel quadro dell'immaginario dell'Oriente che si sviluppa nella cultura russa si colloca la suite sinfonica Sekherezada op. 35 di Nikolaj Andreevič Rimskij-Korsakov: temi popolari di sapore orientaleggiante si sviluppano su impianti sonori di grande effetto che trasportano gli uditori in un mondo lontano, sconosciuto, immaginato, chiamato Oriente

As a consequence of the multitude of exotic cliché shaped by the eighteenth-century orientalistic tradition, the East has always fallen victim to a series of misleading stereotypes from which we can hardly set free.The aim of this paper is to bring to light and demythologize some of those cliché, with particular attention paid to the eighteenth-century musical output in Russia. Among the Russian musical works that focus on the theme of the East is the symphonic suite Sekherezada op. 35 composed by Nikolaj Andreevič Rimskij-Korsakov: oriental-sounding folk themes develop on impressive sonorities taking the listener to a far-away, unknown, imaginary place, called “East”.

Universal inversion formulas for recovering a function from spherical means

description: The problem of reconstruction a function from spherical means is at the heart of several modern imaging modalities and other applications. In this paper we derive universal back-projection type reconstruction formulas for recovering a function in arbitrary dimension from averages over spheres centered on the boundary an arbitrarily shaped smooth convex domain. Provided that the unknown function is supported inside that domain, the derived formulas recover the unknown function up to an explicitly computed smoothing integral operator. For elliptical domains the integral operator is shown to vanish and hence we establish exact inversion formulas for recovering a function from spherical means centered on the boundary of elliptical domains in arbitrary dimension.

Hārūn al-Rashīd (r. 170/786-193/809) e al-Muqtadir (r. 295/908-320/932) divennero, pochi decenni dopo la loro morte, il paradigma del buono e del cattivo califfo rispettivamente; tuttavia, i loro lunghi califfatia le loro biografie personali presentano diversi elementi comuni. Un'analisi  di temi simili presenti nelle rappresentazioni dei due sovrani illustrano mezzi e strategie narrativi impiegati dalle fonti, nel tentativo di stabilire quali fattori determinino lo sviluppo di una reputazione post-mortem positiva o negativa.

This paper looks at how the lives and reigns of two Abbasid caliphs are portrayed and evaluated in medieval Arabic narrative sources. Hārūn al-Rashīd (r. 170/786-193/809) and al-Muqtadir (r. 295/908-320/932) became, only a few decades after their death, the paradigm of the good and the bad caliph respectively. However, their long caliphates as well as their personal biographies share several elements. An analysis of similar themes in the portrayals of the two rulers illustrates narrative means and strategies employed by the sources, in an attempt to establish which factors determine the development of a positive or negative post-mortem reputation.

description: The munuSSM is a supersymmetric model that has been proposed to solve the problems generated by other supersymmetric extensions of the standard model of particle physics. Given that R-parity is broken in the munuSSM, the gravitino is a natural candidate for decaying dark matter since its lifetime becomes much longer than the age of the Universe. In this model, gravitino dark matter could be detectable through the emission of a monochromatic gamma ray in a two-body decay. We study the prospects of the Fermi-LAT telescope to detect such monochromatic lines in 5 years of observations of the most massive nearby extragalactic objects. The dark matter halo around the Virgo galaxy cluster is selected as a reference case, since it is associated to a particularly high signal-to-noise ratio and is located in a region scarcely affected by the astrophysical diffuse emission from the galactic plane. The simulation of both signal and background gamma-ray events is carried out with the Fermi Science Tools, and the dark matter distribution around Virgo is taken from a N-body simulation of the nearby extragalactic Universe, with constrained initial conditions provided by the CLUES project. We find that a gravitino with a mass range of 0.6 to 2 GeV, and with a lifetime range of about 3x10^27 to 2x10^28 s would be detectable by the Fermi-LAT with a signal-to-noise ratio larger than 3. We also obtain that gravitino masses larger than about 4 GeV are already excluded in the munuSSM by Fermi-LAT data of the galactic halo

Refracted Gazes: A Woman Photographer during Mandate Lebanon
Creators: name: Nachabe, Yasmine
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Cultural photography; Middle East; Gender representation; Mandate Lebanon; Women’s movement

description: The fall of the Ottoman Empire and the establishment of the French Mandate created many conflicts and much debate in the Middle East region. The paper will attempt to answer the following questions: How were these conflicts in the context of Lebanon represented through Marie al-Khazen’s (1899-1983) photographs? What does the change in pose and attire signify within an emerging culture caught between the two imperial powers of the Ottoman Empire and the French mandate? And where can ‘modernity’ be located between the rural subject and the urban subject?
Unlike the mainstream representational strategies of Middle Eastern women which were structured around white male European fantasies of the sort that circulated widely at the turn of the Twentieth-Century in images such as Marie Lydie Bonfils’s (1837-1919) bedouin woman, in Marie al-Khazen’s photographs, women projected a local female subjectivity.
This paper explores the relationship between modernity and femininity as manifest through the women’s activity, gaze and attire in Marie al-Khazen as well as other photographs taken in the Middle East region between the 1930s and the 1940s. Al-Khazen and the women represented in the photographs of this period were part of a cosmopolitan sensibility that reveals the Middle East region to be far more international than one might have imagined. Caught between projecting a self-image of the cosmopolitan woman and one of the traditional bedouin, these photographs provide a rich field for tracking the ambiguities of the modern.

Orientalizing Vietnam: The American Cold War, its “Problems” with Refugee Handicraft Artisans, and their Relationship to Barthes’s Mythology
Creators: name: Way, Jennifer
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Vietnam, Orientalism, mythology, refugee, handicraft, salvage

description: This paper examines discourses of orientalism narrating the political and cultural significance of representations of Vietnamese handicraft that the U.S. State Department’s International Cooperation Administration’s handicraft production and export program in Southeast Asia published in American craft, design and art journals and used in trade and department store exhibitions from 1955 to 1961. The American program to bring economic stability to the region developed in response to anxiety about the spread of communism in Southeast Asia, which intensified following the end of the first Indochina War, the French departing Vietnam in 1954 and Vietnam dividing at the 17th Parallel a year later.
At issue are the ways those who implemented the program narrated the Vietnamese handicraft artisans as problems by treating both their plight as political refugees fleeing from communist forces in the north and the vulnerability of their fledgling nation in the south to communism, as a Cold War American Orientalist tale of the U.S. salvaging Vietnam from political uncertainty including the destruction of its potential democracy and capitalism. To this point, the Orientalizing saturates Russel Wright’s article, “Gold Mine in Southeast Asia,” which overlays relationships of Western power and civilization as well as anthropological notions of salvage over references to the ways an ostensibly timeless albeit primitive culture of a non-western society (Vietnam) could maintain its essential identity by serving the needs of an overly industrialized one. Of particular interest are thematic correspondences between the Orientalist thrust of the American cultural diplomacy as evidenced in Wright’s article, and Roland Barthes’ early work, especially “Myth Today”.

description: A celebrated theorem of Kapranov states that the Atiyah class of the tangent bundle of a complex manifold $X$ makes $T_X[-1]$ into a Lie algebra object in $D^+(X)$, the bounded below derived category of coherent sheaves on $X$. Furthermore Kapranov proved that, for a Kähler manifold $X$, the Dolbeault resolution $Ω^{\bullet-1}(T_X^{1,0})$ of $T_X[-1]$ is an $L_\infty$ algebra. In this paper, we prove that Kapranov's theorem holds in much wider generality for vector bundles over Lie pairs. Given a Lie pair $(L,A)$, i.e. a Lie algebroid $L$ together with a Lie subalgebroid $A$, we define the Atiyah class $α_E$ of an $A$-module $E$ (relative to $L$) as the obstruction to the existence of an $A$-compatible $L$-connection on $E$. We prove that the Atiyah classes $α_{L/A}$ and $α_E$ respectively make $L/A[-1]$ and $E[-1]$ into a Lie algebra and a Lie algebra module in the bounded below derived category $D^+(\mathcal{A})$, where $\mathcal{A}$ is the abelian category of left $\mathcal{U}(A)$-modules and $\mathcal{U}(A)$ is the universal enveloping algebra of $A$. Moreover, we produce a homotopy Leibniz algebra and a homotopy Leibniz module stemming from the Atiyah classes of $L/A$ and $E$, and inducing the aforesaid Lie structures in $D^+(\mathcal{A})$.

Intercellular junction disassembly : assigning a function to apical tubulobulbar complexes in testis
Creators: name: Young, J'Nelle Sarah
Publisher: name: University of British Columbia
Year: 2013

description: The focus of this thesis is the characterization of apical tubulobulbar complexes in mammalian testis. These double-membrane, actin-based structures form at sites of attachment between germ cells and Sertoli cells. The location, timing and morphology of these complexes have inspired several proposed functions. It has been proposed that tubulobulbar complexes serve as an anchor to prevent early release of spermatids from the epithelium or that they are a device for elimination of excess cytoplasm. I hypothesize that tubulobulbar complexes are subcellular machines responsible for the internalization of intact intercellular junctions thereby contributing to the process of spermatid release from the seminiferous epithelium. A descriptive approach is taken to determine if key components that are present at similar structures in other systems also are present at tubulobulbar complexes, to determine if integral junction molecules are present at tubulobulbar complexes and to determine the fate of internalized junction material. A functional approach is taken to deplete the expression of an actin-based protein that is localized to tubulobulbar complexes to test the prediction that the structures are involved with spermatid release. Dendritic actin components were localized around the cuff of tubulobulbar complexes and clathrin was localized to coated pits at the ends of the structures. Based on these data, a model of tubulobulbar complex formation was proposed that incorporates clathrin-mediated endocytosis and dendritic actin assembly. Junction molecules known to be present at ectoplasmic specializations were found in vesicles at the ends of tubulobulbar complexes that label positively for early endosome markers. Interestingly, junction protein nectin 2 was colocalized with recycling marker Rab11 at newly forming junctions deeper in the epithelium. This suggests that recycling of junctional proteins may be occurring in Sertoli cells. Finally, depletion of cortactin, a key protein at tubulobulbar complexes, resulted in a short phenotype – an indication that the structures were not able to acquire or maintain their normal length after treatment. Significantly, delay in spermatid release was detected. The data presented here supports the junction internalization hypothesis and introduces a new paradigm for junction internalization generally in cells and links the mechanism to a biologically significant event – sperm release.

description: We discuss the imaging properties of uniaxial epsilon-near-zero metamaterial slabs with possibly tilted optical axis, analyzing their sub-wavelength focusing properties as a function of the design parameters. We derive in closed analytical form the associated two-dimensional Green's function in terms of special cylindrical functions. For the near-field parameter ranges of interest, we are also able to derive a small-argument approximation in terms of simpler analytical functions. Our results, validated and calibrated against a full-wave reference solution, expand the analytical tools available for computationally-efficient and physically-incisive modeling and design of metamaterial-based sub-wavelength imaging systems.

Triaxiality, principal axis orientation and non-thermal pressure in Abell 383

description: While clusters of galaxies are regarded as one of the most important cosmological probes, the conventional spherical modeling of the intracluster medium (ICM) and the dark matter (DM), and the assumption of strict hydrostatic equilibrium (i.e., the equilibrium gas pressure is provided entirely by thermal pressure) are very approximate at best. Extending our previous works, we developed further a method to reconstruct for the first time the full three-dimensional structure (triaxial shape and principal axis orientation) of both DM and intracluster (IC) gas, and the level of non-thermal pressure of the IC gas. We outline an application of our method to the galaxy cluster Abell 383, taken as part of the CLASH multi-cycle treasury program, presenting results of a joint analysis of X-ray and strong lensing measurements. We find that the intermediate-major and minor-major axis ratios of the DM are 0.71+/-0.10 and 0.55+/-0.06, respectively, and the major axis of the DM halo is inclined with respect to the line of sight of 21.1+/-10.1 deg. The level of non-thermal pressure has been evaluated to be about 10% of the total energy budget. We discuss the implications of our method for the viability of the CDM scenario, focusing on the concentration parameter C and the inner slope of the DM gamma, since the cuspiness of dark-matter density profiles in the central regions is one of the critical tests of the cold dark matter (CDM) paradigm for structure formation: we measure gamma=1.02+/-0.06 on scales down to 25 Kpc, and C=4.76+/-0.51, values which are close to the predictions of the standard model, and providing further evidences that support the CDM scenario. Our method allows us to recover the three-dimensional physical properties of clusters in a bias-free way, overcoming the limitations of the standard spherical modelling and enhancing the use of clusters as more precise cosmological probes.

description: Objective: An increasing number of studies suggest that sleep disordered breathing (SDB) may be associated with postoperative atrial fibrillation (POAF), but these studies present discrepant results. Thus, this meta-analysis aimed to synthesize the data associating SDB with POAF in patients who underwent cardiac surgery. Methods: A literature search was performed in the Scopus, PubMed, Web of Science, EMBASE, CENTRAL, Weipu, Wanfang Data, and China National Knowledge Infrastructure databases before August 2022. Data were extracted, and the strength of the relationship between SDB and the risk of POAF was evaluated using odds ratio (OR) and 95% confidence intervals (CIs). All statistical analysis was carried out using the Stata 12.0 software. Results: A total of 24 studies with 660,685 subjects were included in current meta-analysis. SDB was significantly associated with the risk of POAF in the patients who underwent cardiac surgery (OR = 1.49; 95% CI, 1.30–1.70; p < .001). Next subgroup analysis revealed that such association may be increased in the group with medical equipment-measured SDB (OR = 2.27; 95% CI, 1.59–3.23; p < .001), prospective studies (OR = 2.17; 95% CI, 1.55–3.03; p < .001), patients without a previous history of atrial fibrillation (OR = 2.04; 95% CI, 1.47–2.82; p < .001), and patients who received a coronary artery bypass graft (OR = 2.10; 95% CI, 1.45–3.05; p < .001). No publication bias was identified. Conclusion: The results of meta-analysis support that SDB may be associated with an increased risk of POAF in patients who had undergone cardiac surgery, and these results should be confirmed in more rigorously designed studies.KEY MESSAGESPatients with SDB who underwent cardiac surgery showed increased risk of POAF.The relationship between SDB and POAF should be explained with caution with the consideration of various covariate.The effect of pre-treatment of SDB on POAF should be examined in future.

Nested BDDC for a saddle-point problem

description: We propose a Nested BDDC for a class of saddle-point problems. The method solves for both flux and pressure variables. The fluxes are resolved in three-steps: the coarse solve is followed by subdomain solves, and last we look for a divergence-free flux correction and pressure variables using conjugate gradients with a Multilevel BDDC preconditioner. Because the coarse solve in the first step has the same structure as the original problem, we can use this procedure recursively and solve (a hierarchy of) coarse problems only approximately, utilizing the coarse problems known from the BDDC. The resulting algorithm thus first performs several upscaling steps, and then solves a hierarchy of problems that have the same structure but increase in size while sweeping down the levels, using the same components in the first and in the third step on each level, and also reusing the components from the higher levels. Because the coarsening can be quite aggressive, the number of levels can be kept small and the additional computational cost is significantly reduced due to the reuse of the components. We also provide the condition number bound and numerical experiments confirming the theory.

description: Spin pumping driven by bistable exchange spin waves is demonstrated in a Pt/Y$_3$Fe$_5$O$_{12}$ film under parametric excitation. In the Pt/Y$_3$Fe$_5$O$_{12}$ film, the spin pumping driven by parametric excitation selectively enhances the relaxation of short-wavelength exchange spin waves, indicating strong coupling between the exchange spin waves and spin currents at the interface through efficient spin transfer. The parametric spin pumping, furthermore, allows direct access to nonlinear spin wave dynamics in combination with the inverse spin Hall effect, revealing unconventional bistability of the exchange spin waves.
