description: $δ$-sunspots, with highly complex magnetic structures, are very productive in energetic eruptive events, such as X-class flares and homologous eruptions. We here study the formation of such complex magnetic structures by numerical simulations of magnetic flux emergence from the convection zone into the corona in an active-region-scale domain. In our simulation, two pairs of bipolar sunspots form on the surface, originating from two buoyant segments of a single subsurface twisted flux rope, following the approach of Toriumi et al. (2014). Expansion and rotation of the emerging fields in the two bipoles drive the two opposite polarities into each other with apparent rotating motion, producing a compact $δ$-sunspot with a sharp polarity inversion line. The formation of the $δ$-sunspot in such a realistic-scale domain produces emerging patterns similar to those formed in observations, e.g. the inverted polarity against Hale's law, the curvilinear motion of the spot, strong transverse field with highly sheared magnetic and velocity fields at the PIL. Strong current builds up at the PIL, giving rise to reconnection, which produces a complex coronal magnetic connectivity with non-potential fields in the Delta-spot overlaid by more relaxed fields connecting the two polarities at the two ends.

description: Noncoding RNAs (ncRNAs) function with associated proteins to effect complex structural and regulatory outcomes. To reveal the composition and dynamics of specific noncoding RNA- protein complexes (RNPs) in vivo, we developed comprehensive identification of RNA-binding proteins by mass spectrometry (ChIRP-MS). ChIRP-MS analysis of four ncRNAs captures key protein interactors, including a U1-specific link to the 3′ RNA processing machinery. Xist, an essential lncRNA for X-chromosome inactivation (XCI), interacts with 81 proteins from chromatin modification, nuclear matrix, and RNA remodeling pathways. The Xist RNA-protein particle assembles in two steps coupled with the transition from pluripotency to differentiation. Specific interactors include HnrnpK that participates in Xist-mediated gene silencing and histone modifications, but not Xist localization and Drosophila Split ends homolog Spen that interacts via the A-repeat domain of Xist and is required for gene silencing. Thus, Xist lncRNA engages with proteins in a modular and developmentally controlled manner to coordinate chromatin spreading and silencing.

description: During the COVID-19 pandemic, wearing a face mask became a global daily practice. Japanese people were already accustomed to wearing masks due to their collectivistic culture, which prioritizes conformity and group harmony. In such a culture, where individuals are concerned about how others perceive them and their actions, wearing masks can be a self-protective action to prevent, escape, or reduce the severity of perceived negative feelings. Previous studies indicate that people experiencing anxiety tend to have negative biases when evaluating emotional expressions on faces. Therefore, we hypothesized that wearing a mask can reduce the negative feelings caused by social pressure, emotion processing, especially intensity perception. While our findings confirmed that wearing a mask reduced negative feelings caused by social pressure, there was no significant change in emotion intensity recognition performance. This null result might be attributed to the small effect size of the association between negative bias in emotion processing and an individual's state. In future studies, it would be valuable to include participants from non-collectivistic cultures to gain a broader understanding of the impact of wearing masks on emotion processing.

description: De novo molecule design has become a highly active research area, advanced significantly through the use of state-of-the-art generative models. Despite these advances, several fundamental questions remain unanswered as the field increasingly focuses on more complex generative models and sophisticated molecular representations as an answer to the challenges of drug design. In this paper, we return to the simplest representation of molecules, and investigate overlooked limitations of classical generative approaches, particularly Variational Autoencoders (VAEs) and auto-regressive models. We propose a hybrid model in the form of a novel regularizer that leverages the strengths of both to improve validity, conditional generation, and style transfer of molecular sequences. Additionally, we provide an in depth discussion of overlooked assumptions of these models' behaviour.

description: There is considerable heterogeneity in immunological parameters between individuals, but its sources are largely unknown. To assess the relative contribution of heritable versus non-heritable factors, we have performed a systems-level analysis of 210 healthy twins between 8–82 years of age. We measured 204 different parameters, including cell population frequencies, cytokine responses, and serum proteins, and found that 77% of these are dominated (> 50% of variance) and 58% almost completely determined (> 80% of variance) by non-heritable influences. In addition, some of these parameters become more variable with age, suggesting the cumulative influence of environmental exposure. Similarly, the serological responses to seasonal influenza vaccination are also determined largely by non-heritable factors, likely due to repeated exposure to different strains. Lastly, in MZ twins discordant for cytomegalovirus infection, over half of all parameters are affected. These results highlight the largely reactive and adaptive nature of the immune system in healthy individuals.

description: Optimally orchestrating complex behavioral states such as the pursuit and consumption of food is critical for an organism’s survival. The lateral hypothalamus (LH) is a neuroanatomical region essential for appetitive and consummatory behaviors, but whether individual neurons within the LH differentially contribute to these interconnected processes is unknown. Here we show that selective optogenetic stimulation of a molecularly defined subset of LH GABAergic (Vgat-expressing) neurons enhances both appetitive and consummatory behaviors, while genetic ablation of these neurons reduced these phenotypes. Furthermore, this targeted LH subpopulation is distinct from cells containing the feeding-related neuropeptides, melanin-concentrating hormone (MCH) and orexin (Orx). Employing in vivo calcium imaging in freely behaving mice, to record activity dynamics from hundreds of cells, we identified individual LH GABAergic neurons that preferentially encode aspects of either appetitive or consummatory behaviors, but rarely both. These tightly regulated, yet highly intertwined, behavioral processes are thus dissociable at the cellular level.

description: Hemicentin has come a long way from when it was first identified in C. elegans as him-4 (High incidence of males). The protein is now a recognized player in maintaining the architectural integrity of vertebrate tissues and organs. Highly conserved hemicentin sequences across species indicate this gene’s ancient evolutionary roots and functional importance. In mouse, hemicentin is liberally distributed on the cell surface of many cell types, including epithelial cells, endothelial cells of the eye, lung, and uterus, and trophectodermal cells of blastocyst. Recent discoveries have uncovered yet another vital purpose of hemicentin 1. The protein also serves a unique function in mitotic cytokinesis, during which this extracellular matrix protein plays a key role in cleavage furrow maturation. Though understanding of hemicentin function has improved through new discoveries, much about this protein remains mysterious.

description: Conformal field theory has turned out to be a powerful tool to derive two-dimensional lattice models displaying fractional quantum Hall physics. So far most of the work has been for lattices with open boundary conditions in at least one of the two directions, but it is desirable to also be able to handle the case of periodic boundary conditions. Here, we take steps in this direction by deriving analytical expressions for a family of conformal field theory states on the torus that is closely related to the family of bosonic and fermionic Laughlin states. We compute how the states transform when a particle is moved around the torus and when the states are translated or rotated, and we provide numerical evidence in particular cases that the states become orthonormal up to a common factor for large lattices. We use these results to find the S-matrix of the states, which turns out to be the same as for the continuum Laughlin states. Finally, we show that when the states are defined on a square lattice with suitable lattice spacing they practically coincide with the Laughlin states restricted to a lattice.

When L is an m-framed n-cable of a knot K in the three-sphere, its sutured annular Khovanov homology carries a commuting action of the symmetric group S_n. One therefore obtains a "knotted" Schur-Weyl representation that agrees with classical sl_2 Schur-Weyl duality when K is the Seifert-framed unknot.

description: Ferromagnetic side layers sandwiching a nonmagnetic spacer as a metallic trilayer has become a pivotal platform for achieving spintronic devices. Recent experiments demonstrate that manipulating the width or the nature of conducting spacer induces noncollinear magnetic alignment between the side layers. Our theoretical analysis reveals that altering the width of spacer significantly affects the interlayer exchange coupling (IEC), resulting in noncollinear alignment. Through analytic and first-principles methods, our study on the Fe/Ag/Fe trilayer shows that at a specific width of the Ag spacer, the magnetic moments of side layers tend to be perpendicular. This alignment is mediated by Ag quantum well states, exhibiting spin spirals across the trilayer. Our results reveal that the noncollinear IEC offers a degree of freedom to control magnetic devices and boot spintronic technology with improved transport capabilities.

CARBON-NITROGEN DOUBLE BOND STEREOSELECTIVE REDUCTION
Creators: name: BONSIGNORE, MARTINA
Publisher: name: Universit� degli Studi di Milano
Year: 2013

description: The carbon-nitrogen double bond reduction represents a powerful and widely used transformation that allows to generate a new nitrogen-bearing stereocenter. Since chiral amino groups are ubiquitous in a variety of bioactive molecules, the development of a catalytic stereoselective process for the preparation of enantiomerically enriched amines by imine reduction is attracting increasing interest. Recently great efforts have been made to develop efficient organocatalytic methods to perform enantioselective imine reductions and reductive amination processes. In particular, research has focused on trichlorosilane-mediated reductions due to the possibility of generating chiral catalysts for imine reduction simply by coordination of HSiCl3 with a chiral Lewis base. This work reports the design and synthesis of new catalytic systems for the reduction of C=N double bond as well as the exploration of new synthetic applications. A set of enantiomerically pure Lewis bases containing different diphenyl phosphinyl oxide groups and proline-based catalysts were developed and successfully used in the trichlorosilane-mediated reduction. A highly stereoselective of N-benzyl enamines was also developed, leading to the synthesis of enantiomerically pure ??lactams. Preliminary experiments allowed to obtain for the first time 1,2,3,4-tetrahydroquinolines via reductive amination with good levels of enantioselection, paving the way for further improvements.

description: Vietnamesische Geistbesessenheit, bekannt als lên đồng und als zentrale rituelle Praxis innerhalb der sogenannten Religion der Muttergottheiten (Ðạo Mẫu oder auch „Weg der vier Paläste“ - Đạo Tứ Phử genannt) kann als vitale religiöse und rituelle Praxis beschrieben werden, die im Laufe ihrer Geschichte und trotz heftiger Kritik und Verurteilung im Namen von Modernität und Fortschritt ihre Anpassungsfähigkeit, ja Resilienz, unter Beweis gestellt hat. In meinem Beitrag möchte ich die Transformations-Dynamiken von einem verbotenen Besessenheitsritual zu seiner Tolerierung bis hin zu seiner Wertschätzung als Ausdruck „authentischer“ vietnamesischer Kultur und kollektiver nationaler Identität nachzeichnen. Den Weg from national shame to national fame skizziere ich über verschiedene Etappen und ‚Artikulationsräume‘ der Folklorifizierung, des experimentellen Kunst-Spektakels und der Heritagisierung und Theatralisierung als Propaganda-Spektakel. Dabei ist die Frage, ob Geistbesessenheit als religiöses Ritual oder gar eine Religion akzeptiert wird, in einem Land wie Vietnam, wo der Staat entscheidet, was eine legitime und erlaubte Religion ist, von politischer Brisanz und Relevanz.
description: Vietnamese mediumship known as lên đồng, a central ritual practice in the context of the so-called Religion of the Mother Goddesses (Ðạo Mẫu, also referred to as “the way of the four palaces”, Đạo Tứ Phử), can be described as a vital religious practice which has proved its resilience and adaptability throughout its history despite persistent criticism in the name of modernity and progress. In this paper I trace the dynamics of the transformation of this practice from a forbidden possession ritual at the centre of the Four Palace Cult (Đạo Tứ Phử) to its toleration and appreciation as an expression of “authentic” Vietnamese culture and collective national identity. I outline this pathfrom national shame to national fame through different stages and ‘spaces of articulation’, such as folklorization, the experimental art spectacle, and heritagization and theatricalization as propaganda spectacle. The question of whether mediumship is accepted as a religious ritual, or even as a religion at all, is of political significance and relevance in a country like Vietnam, where the state judges the legitimacy of religion.

description: The facility location problem (FLP) is a classical combinatorial optimization challenge aimed at strategically laying out facilities to maximize their accessibility. In this paper, we propose a reinforcement learning method tailored to solve large-scale urban FLP, capable of producing near-optimal solutions at superfast inference speed. We distill the essential swap operation from local search, and simulate it by intelligently selecting edges on a graph of urban regions, guided by a knowledge-informed graph neural network, thus sidestepping the need for heavy computation of local search. Extensive experiments on four US cities with different geospatial conditions demonstrate that our approach can achieve comparable performance to commercial solvers with less than 5\% accessibility loss, while displaying up to 1000 times speedup. We deploy our model as an online geospatial application at https://huggingface.co/spaces/randommmm/MFLP.

LE STROFI SAFFICHE IN ORAZIO, AUSONIO E PRUDENZIO: TRA INNODIA E POESIA PROFANA
Creators: name: CASTELNUOVO, ELENA
Publisher: name: Universit� degli Studi di Milano
Year: 2018

description: This dissertation deals with the Sapphic stanzas composed by an ancient poet, Horace, and by two late Latin poets, Ausonius and Prudentius. In the first chapter I point out that from Horace to medieval poetry there is a strict connection between the Sapphic meter and hymnody; Prudentius is a key figure in the evolution of the poetry in Sapphics: he is the link between Horace?s Sapphic poems and medieval hymns. Then, I state that Christian hymnodists considered Horace their classical antecedent in the genre of hymnody, along with David, whose Psaltery is a model for Christian hymns. The second and the third chapters are the core of my dissertation: they focus on Prudentius? Cath. 8 and its relationship with Horace?s Carmen saeculare. I first examine the collocation of Cath. 8 in the collection of the hymns for every hour, then I analyse its biblical narrative, in which I find a baptismal symbolism. In the third chapter, I try not to be influenced by political prejudices on the Secular song, but I seek to read Horace?s poem as late antique poets read it ? as a hymn, not as a political ode. At the end of my analysis of Horace?s influence on Cath. 8, I draw the conclusion that Prudentius recalls just those Horatian poems that can be considered hymns or odes on morality. After that, I address the issue of the singing of Horace?s poems through the centuries and last I focus on phonic and rhythmic aspects of Prudentius? lyrical poetry. In the last chapter I investigate the relationship between Horace and Ausonius through the perspective of a single poem, Ephem. 1; a metaliterary reflection at the end of Ephem. 1 paves the way to a metapoetical use of the Sapphic stanzas. Finally, I compare Prudentius? Cathemerinon with Ausonius? Ephemeris in order to see how Prudentius both recalls and distances himself from Ausonius? poetry.

description: Fast growing malignant cancers represent a major therapeutic challenge. Basic cancer research has concentrated efforts to determine the mechanisms underlying cancer initiation and progression and reveal candidate targets for future therapeutic treatment of cancer patients. With known roles in fundamental processes required for proper development and function of the nervous system, L1-CAMs have been recently identified as key players in cancer biology. In particular L1 has been implicated in cancer invasiveness and metastasis, and has been pursued as a powerful prognostic factor, indicating poor outcome for patients. Interestingly, L1 has been shown to be important for the survival of cancer stem cells, which are thought to be the source of cancer recurrence. The newly recognized roles for L1CAMs in cancer prompt a search for alternative therapeutic approaches. Despite the promising advances in cancer basic research, a better understanding of the molecular mechanisms dictating L1-mediated signaling is needed for the development of effective therapeutic treatment for cancer patients.

description: Let $\langle G_r,G_b \rangle$ be a pair of plane $st$-graphs with the same vertex set $V$. A simultaneous visibility representation with L-shapes of $\langle G_r,G_b \rangle$ is a pair of bar visibility representations $\langleΓ_r,Γ_b\rangle$ such that, for every vertex $v \in V$, $Γ_r(v)$ and $Γ_b(v)$ are a horizontal and a vertical segment, which share an end-point. In other words, every vertex is drawn as an $L$-shape, every edge of $G_r$ is a vertical visibility segment, and every edge of $G_b$ is a horizontal visibility segment. Also, no two L-shapes intersect each other. An L-shape has four possible rotations, and we assume that each vertex is given a rotation for its L-shape as part of the input. Our main results are: (i) a characterization of those pairs of plane $st$-graphs admitting such a representation, (ii) a cubic time algorithm to recognize them, and (iii) a linear time drawing algorithm if the test is positive.

MSA is clinically characterized by parkinsonism, cerebellar ataxia, dysautonomia and pyramidal signs. Two subtypes of the disease can be distinguished, MSA-P and MSA-C, on the basis of the predominant symptomatology, parkinsonian or cerebellar respectively. From a neuropathological point of view, MSA is classified as an alpha-synucleinopathy. However, differently from Parkinson?s disease and Dementia with Lewy bodies, the main intracellular localization of alpha-synuclein aggregates in MSA is not the neuron, but the oligodendrocyte. An effective therapy is not available yet. The pathogenesis of the disease is almost completely unknown and the available models, mainly transgenic animals overexpressing human alpha-synuclein under the promoter of genes specifically expressed in oligodendrocytes, do not fully recapitulate the pathogenic mechanisms. The aim of the present project was the generation and study of new experimental models for the identification of the molecular mechanisms of the disease and new therapeutic targets. The study has taken advantage from the use of peripheral blood cells, fibroblasts? primary cultures, iPSC-derived dopaminergic neurons and brain tissue and has focused on several topics, including autophagy, mitochondrial functioning and alpha-synuclein expression. The main findings in patients have been: an increase of mtDNA amount in peripheral blood cells and in brain tissue, selectively in the cerebellar subtype; an impairment of mitochondrial respiratory chain activity in fibroblasts and iPSC-derived neurons; an increase of mitochondrial mass and of complex II amount, an increased expression of mitochondria-related genes, an increase of the amount of many enzymes involved in the synthesis of Coenzyme Q10 in neurons; an impairment of the autophagic pathway in neurons; a reduced expression of neuronal markers in advanced stages of dopaminergic differentiation; hypomethylation of a CpG island located in alpha-synuclein intron 1. The generation and characterization of the iPSC-derived neuronal model is particularly remarkable because it represents the first comprehensive model of MSA based on this technique. In conclusion, this project has led to the identification of several defects in MSA cells and tissues, suggesting the impairment of specific molecular pathways and contributing to the understanding of the underlying pathogenic mechanisms. Furthermore, this study lays the foundations for several lines of investigation and the proposed model can also have remarkable therapeutic implications for the assessment of effectiveness and tolerability of new pharmacological compounds.

description: The goal of this paper is to prove an equivalence between the model categorical approach to pro-categories, as studied by Isaksen, Schlank and the first author, and the $\infty$-categorical approach, as developed by Lurie. Three applications of our main result are described. In the first application we use (a dual version of) our main result to give sufficient conditions on an $ω$-combinatorial model category, which insure that its underlying $\infty$-category is $ω$-presentable. In the second application we consider the pro-category of simplicial étale sheaves and use it to show that the topological realization of any Grothendieck topos coincides with the shape of the hyper-completion of the associated $\infty$-topos. In the third application we show that several model categories arising in profinite homotopy theory are indeed models for the $\infty$-category of profinite spaces. As a byproduct we obtain new Quillen equivalences between these models, and also obtain an example which settles negatively a question raised by Raptis.

description: We demonstrate a simple scheme to reach Bose-Einstein condensation (BEC) of metastable triplet helium atoms using a single beam optical dipole trap with moderate power of less than 3 W. Our scheme is based on RF-induced evaporative cooling in a quadrupole magnetic trap and transfer to a single beam optical dipole trap that is located below the magnetic trap center. We transfer 1x10^6 atoms into the optical dipole trap, with an initial temperature of 14 μK, and observe efficient forced evaporative cooling both in a hybrid trap, in which the quadrupole magnetic trap operates just below the levitation gradient, and in the pure optical dipole trap, reaching the onset of BEC with 2x10^5 atoms and a pure BEC of 5x10^4 atoms. Our work shows that a single beam hybrid trap can be applied for a light atom, for which evaporative cooling in the quadrupole magnetic trap is strongly limited by Majorana spin-flips, and the very small levitation gradient limits the axial confinement in the hybrid trap.

Axon–glial interactions at the Drosophila CNS midline
Creators: name: Crews, Stephen T.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: The glia that reside at the midline of the Drosophila CNS are an important embryonic signaling center and also wrap the axons that cross the CNS. The development of the midline glia (MG) is characterized by migration, ensheathment, subdivision of axon commissures, apoptosis, and the extension of glial processes. All of these events are characterized by cell-cell contact between MG and adjacent neurons. Cell adhesion and signaling proteins that mediate different aspects of MG development and MG-neuron interactions have been identified. This provides a foundation for ultimately obtaining an integrated picture of how the MG assemble into a characteristic axonal support structure in the CNS.
On a conjecture regarding Fisher information

description: Fisher's information measure plays a very important role in diverse areas of theoretical physics. The associated measures as functionals of quantum probability distributions defined in, respectively, coordinate and momentum spaces, are the protagonists of our present considerations. The product of them has been conjectured to exhibit a non trivial lower bound in [Phys. Rev. A (2000) 62 012107]. We show here that such is not the case. This is illustrated, in particular, for pure states that are solutions to the free-particle Schrödinger equation. In fact, we construct a family of counterexamples to the conjecture, corresponding to time-dependent solutions of the free-particle Schrödinger equation. We also give a new conjecture regarding any normalizable time-dependent solution of this equation.

description: Enabled by large annotated datasets, tracking and segmentation of objects in videos has made remarkable progress in recent years. Despite these advancements, algorithms still struggle under degraded conditions and during fast movements. Event cameras are novel sensors with high temporal resolution and high dynamic range that offer promising advantages to address these challenges. However, annotated data for developing learning-based mask-level tracking algorithms with events is not available. To this end, we introduce: ($i$) a new task termed \emph{space-time instance segmentation}, similar to video instance segmentation, whose goal is to segment instances throughout the entire duration of the sensor input (here, the input are quasi-continuous events and optionally aligned frames); and ($ii$) \emph{\dname}, a dataset for the new task, containing aligned grayscale frames and events. It includes annotated ground-truth labels (pixel-level instance segmentation masks) of a group of up to seven freely moving and interacting mice. We also provide two reference methods, which show that leveraging event data can consistently improve tracking performance, especially when used in combination with conventional cameras. The results highlight the potential of event-aided tracking in difficult scenarios. We hope our dataset opens the field of event-based video instance segmentation and enables the development of robust tracking algorithms for challenging conditions.\url{https://github.com/tub-rip/MouseSIS}
