The untwisting number of a knot

Subjects: subject: Geometric Topology (math.GT)

description: The unknotting number of a knot is the minimum number of crossings one must change to turn that knot into the unknot. The algebraic unknotting number is the minimum number of crossing changes needed to transform a knot into an Alexander polynomial-one knot. We work with a generalization of unknotting number due to Mathieu-Domergue, which we call the untwisting number. The untwisting number is the minimum number (over all diagrams of a knot) of right- or left-handed twists on even numbers of strands of a knot, with half of the strands oriented in each direction, necessary to transform that knot into the unknot. We show that the algebraic untwisting number is equal to the algebraic unknotting number. However, we also exhibit several families of knots for which the difference between the unknotting and untwisting numbers is arbitrarily large, even when we only allow twists on a fixed number of strands or fewer.

description: In a current-carrying single-molecular junction (SMJ), a hierarchy of hybrid energy transport processes takes place under a highly nonequilibrium situation, including energy transfer from electrons to molecular vibrations via electron-vibration interaction, energy redistribution within different vibrational modes via anharmonic coupling, and eventual energy transport to surrounding electrodes. A comprehensive understanding of such processes is a prerequisite for their potential applications as single-molecular devices. $Ab$ $initio$ current-induced molecular dynamics (MD) is an ideal approach to address this complicated problem. But the computational cost hinders its usage in systematic study of realistic SMJs. Here, we achieve orders of magnitude improvement in the speed of MD simulation by employing machine-learning potential with accuracy comparable to density functional theory. Using this approach, we show that SMJs with graphene electrodes generate order of magnitude less heating than those with gold electrodes. Our work illustrates the superior heat transport property of graphene as electrodes for SMJs, thanks to its better phonon spectral overlap with molecular vibrations.

description: The Basilian monks of the greek’s rite, are rooted in the whole territory of Messina and build many monasteries. Among the most important archimandriato of the Holy Savior of Messina, main church of the order, and the monastery of San Filippo of Demenna (or Fragalà), near to Frazzanò, in the province of Messina. The two monasteries are linked not only by the period of the foundation but also from the relationship between both the Norman house of Sicily, in fact Adelaide del Vasto, wife of Roger I and mother of Roger II, despite being the cause of the Latinization of the island protect both monasteries and endows them with possessions that ensure survival. Both buildings are the subject of the restoration based on an anti-sismic intervention, the archimandriato in the first half of the seventeenth century, while Fragalà in the first half of the twentieth century, in both cases we see how the focus on the existing structures and the use of materials try to ensure the buildings "durability" to the earthquake.

description: In a recent work [A. Deger et al., Phys. Rev. Lett. 129, 160601 (2022)] we have shown that kinetic constraints can completely arrest many-body chaos in the dynamics of a classical, deterministic, translationally-invariant spin system with the strength of the constraint driving a dynamical phase transition. Using extensive numerical simulations and scaling analyses we demonstrate here that this constraint-induced phase transition lies in the directed percolation universality class in both one and two spatial dimensions.

How can workforce development programs impact social determinants of health for at-risk youth?
Creators: name: Venable, Catie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Objective: Mapping the options and opportunities in the workforce development space to support the increasing number of companies that seek to engage with their communities in this way, leading to the implementation of impactful programs. Ultimately, the objective is that at-risk youth in the United States will experience improved long-term health outcomes due to increased employment, education, and income after participating in these programs.Methods: This study consisted of two components: 1) A literature review to identify the types of partnerships, both successful and unsuccessful, being used to deliver vocational training to disadvantaged youth aged 16-24 with the goal of increasing their employment opportunity and income. 2) Stakeholder interviews to further explain trends in the structure of successful programs. Interviews were conducted with eight program leaders and four policy experts.Results: There are five macro-level goals for workforce development programs implemented in the United States. Within that framework, programs must decide how to structure themselves based on six fundamental dimensions: intermediary, targeted groups, scale, focus, funding, and private sector participation. All program types face some of the same challenges and opportunities, but program strengths also vary based on the structural decisions they’ve made. Key themes include: 1) Programs with the strongest private sector partnerships are proactive about changing employer mentalities. 2) Programs that achieve strong employer engagement do so by presenting them with a viable business case. However, few programs have dedicated adequate attention to funding sustainability. 3) Regardless of what type of intermediary is leading the program, engagement from both the educational system and business community is key. 4) While grant funding is critical to most programs, they should consider how it complicates their missions. 5) Few programs are incorporating any metrics related to health, which represents an area of opportunity for those seeking a holistic approach.Conclusion: There are many different ways successful workforce development programs serving at-risk youth can be structured, and there is no one-size-fits-all approach. There are several important choices that must be made when developing a program, and each one has different trade-offs which will cause programs to be more or less geared towards certain participant groups.
Mistica e filosofia

description: La mistica, come esperienza dello spirito, è conoscenza dell’essenza dell’uomo, ben più profonda delle psicologie contemporanee. È attività eminentemente razionale, la stessa della filosofia: entrambe sono infatti fondate sul distacco, il platonico esercizio di morte, che conduce alla scoperta del fondo dell’anima, ovvero allo spirito. Il carattere religioso della mistica, ma anche della filosofia, sta nella fede, che non è credenza, ma movimento verso l’assoluto, e perciò rimozione di ogni relativo, ivi compreso quello religioso. La mistica porta a superare l’alterità del divino, così un sottile confine la separa da quell’ ateismo definito appunto “mistico”. Mysticism, as experience of the spirit, is knowledge of the human essence, much deeper than contemporary psychology. It is a rational activity, like philosophy: in fact both are constituted by detachment - the platonic “exercise to death” - which leads to the discovery of the “ground of the soul”, or spirit. The religious character of mysticism, and of philosophy too, is faith, which is not belief, but movement towards the Absolute, and removal of every non-absolute knowledge. Mysticism leads to overcome the alterity of God; therefore, there is a thin boundary between it and that form of atheism, which is called “mystical atheism”.

Electronic structure and weak itinerant magnetism in metallic Y2Ni7

Publisher: name: arXiv
Year: 2015
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We report a density functional study of the electronic structure and magnetism of Y2Ni7. The results show itinerant magnetism very similar to that in the weak itinerant ferromagnet Ni3Al. The electropositive Y atoms in Y2Ni7 serves to donate charge to the Ni host mostly in the form of $s$ electrons. The non-spin-polarized state shows a high density of states at the Fermi level, N(EF) due to flat bands. This leads to the ferromagnetic instability. However, there are also several much more dispersive bands crossing E(F), which should promote the conductivity. Spin fluctuation effects appear to be comparable to or weaker than Ni3Al, based on comparison with experimental data. Y2Ni7 provides a uniaxial analogue to cubic Ni3Al for studying weak itinerant ferromagnetism, suggesting detailed measurements of its low temperature physical properties and spin fluctuations, as well experiments under pressure.

description: This study considers the problem of the extreme behavior exhibited by solutions to Burgers equation subject to stochastic forcing. More specifically, we are interested in the maximum growth achieved by the "enstrophy" (the Sobolev $H^1$ seminorm of the solution) as a function of the initial enstrophy $\mathcal{E}_0$, in particular, whether in the stochastic setting this growth is different than in the deterministic case considered by Ayala \& Protas (2011). This problem is motivated by questions about the effect of noise on the possible singularity formation in hydrodynamic models. The main quantities of interest in the stochastic problem are the expected value of the enstrophy and the enstrophy of the expected value of the solution. The stochastic Burgers equation is solved numerically with a Monte Carlo sampling approach. By studying solutions obtained for a range of optimal initial data and different noise magnitudes, we reveal different solution behaviors and it is demonstrated that the two quantities always bracket the enstrophy of the deterministic solution. The key finding is that the expected values of the enstrophy exhibit the same power-law dependence on the initial enstrophy $\mathcal{E}_0$as reported in the deterministic case. This indicates that the stochastic excitation does not increase the extreme enstrophy growth beyond what is already observed in the deterministic case.

description: The node set of a two-mode network consists of two disjoint subsets and all its links are linking these two subsets. The links can be weighted. We developed a new method for identifying important sub-networks in two-mode networks. The method combines and extends the ideas from generalized cores in one-mode networks and from (p, q)- cores for two-mode networks. In this paper we introduce the notion of generalized two-mode cores and discuss some of their properties. An efficient algorithm to determine generalized two-mode cores and an analysis of its complexity are also presented. For illustration some results obtained in analyses of real-life data are presented.

description: The lanthanide pyrochlore oxides Ln$_2$B$_2$O$_7$ are one of the most intensely studied classes of materials within condensed matter physics, firmly centered as one of the pillars of frustrated magnetism. The extensive chemical diversity of the pyrochlores, coupled with their innate geometric frustration, enables realization of a wide array of exotic and complex magnetic ground states. Thus, the discovery of new pyrochlore compositions has been a persistent theme that continues to drive the field in exciting directions. The recent focus on the mixed B-site pyrochlores offers a unique route towards tuning both local coordination chemistry and sterics, while maintaining a nominally pristine magnetic sublattice. Here, we present a broad overview of the pyrochlore stability field, integrating recent synthetic efforts in mixed B-site systems with the historically established Ln$_2$B$_2$O$_7$ families. In parallel, we present the discovery and synthesis of the entire Ln$_2$InSbO$_7$ family (Ln: La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) located near the boundary of the pyrochlore stability field using a rapid, hybrid mechanicochemical/microwave-assisted synthesis technique. Magnetic characterization on the entire class of compounds draws striking parallels to the stannate analogs, suggesting that these compounds may host a breadth of exotic magnetic ground states.
Alternative Splicing of the Human AS3MT Gene Based on Number of Variable Nucleotide Tandem Repeats
Creators: name: Dontu, Pragnya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Arsenic is an environmental toxin that is metabolized in humans by reduction and methylation of inorganic arsenic. Arsenite methyltransferase, encoded by AS3MT, methylates trivalent arsenic so that it can be excreted in urine. Genetic studies indicate that variants at the AS3MT locus confer risk for the development of schizophrenia. Alternate splicing of this gene leads to the production of an alternate isoform, AS3MTd2d3, predominately in the brain, and this alternative isoform is present at higher levels in tissue from individuals with schizophrenia. AS3MTd2d3, lacks arsenite methyltransferase activity, and its formation is linked to variable nucleotide tandem repeats (VNTRs) in exon 1 of AS3MT. It is hypothesized that VNTR copy number determines the relative production of the two transcripts by altering DNA methylation at the locus, and this in turn alters risk for schizophrenia. This hypothesis is tested using embryonic stem (ES) cell lines humanized with either the common AS3MT allele, an allele with three VNTRs in exon 1, or humanized with an allele we generated that carries four VNTRs. Expression of the two AS3MT isoforms is compared in ES cell lines that carry either the triple or quadruple VNTR human DNA. While no correlation between VNTR number and ratio of the AS3MTd2d3 isoform exists in ES cells, the ES cells will be differentiated into neuronal cells for further analysis to confirm or deny the original hypothesis.

description: We develop a time-dependent Schrieffer-Wolff-Lindblad perturbation theory to study effective interactions for driven open quantum systems. The starting point of our analysis is a given Lindblad equation, based on which we obtain an effective (averaged) map that describes the renormalization of both the Hamiltonian and collapse operators due to the drive. As a case study, we apply this method to the dispersive readout of a transmon qubit and derive an effective disperive map that describes measurement-induced dephasing and Stark shift for the transmon. The effective map we derive is completely positive and trace-preserving under adiabatic resonator response. To benchmark our method, we demonstrate good agreement with a numerical computation of the effective rates via the Lindbladian spectrum. Our results are also in agreement with, and extend upon, an earlier derivation of such effects by Gambetta et al. (Phys. Rev. A 74, 042318 (2006)) using the positive P-representation for the resonator field.

description: We study tunnel junctions consisting of a two-dimensional ferroelectric (FE) material sandwiched between graphene electrodes. We formulate a theory for the interplay of the FE polarization and induced free charges in such devices, taking into account quantum capacitance effects. We predict a gate-sensitive FE voltage difference across the device, which can be measured using electrostatic force microscopy. Incorporating this electrostatic theory in the tunneling current-voltage characteristics, we identify a resonance peak associated with aligned Dirac cones as a highly sensitive probe of the FE polarization of the junction. This opens the way for device applications with few atom-thick FE layers acting as readable ultra-high-density memory.

description: Objective: Examine the online industry for kratom (Mitragyna speciosa), a plant-based substance used by Americans as an opioid alternative, and provide context to the market amidst regulatory attempts by the Food and Drug Administration and numerous state legislatures.  Methods: Using search results collected from the three most widely used search engines, 663 websites were identified selling kratom products to US consumers. The top 100 most visited online vendors were selected and the content of their website and social media profiles were coded for topics including location, payment and shipping options, age verification, health warnings and disclaimers, grassroots advocacy regarding upcoming state and federal regulations, and response to the recent kratom-linked Salmonella outbreak.  Results:  25% of vendors made claims that kratom provided relief from opioid withdrawal. 81% of vendors featured a disclaimer that kratom is addictive, with 54% stating that the product is not FDA approved. Only 5% of vendors utilized effective age verification through confirming age on delivery or use of a third party online database. Enforcement of state and locality bans on the vendor's part varied by location; 65% vendors did not sell to Indiana whereas only 27% prohibited sales to Rhode Island. Conclusions:  The kratom internet vendor industry (KIV) was found to have low adherence to US state-level restrictions on the products’ purchase. There is a high prevalence of health claims featured on vendor webpages that are discouraged by the Food and Drug Administration.

Quantum Phase Transition and Protected Ideal Transport in a Kondo Chain

description: We study the low energy physics of a Kondo chain where electrons from a one-dimensional band interact with magnetic moments via an anisotropic exchange interaction. It is demonstrated that the anisotropy gives rise to two different phases which are separated by a quantum phase transition. In the phase with easy plane anisotropy, Z$_2$ symmetry between sectors with different helicity of the electrons is broken. As a result, localization effects are suppressed and the dc transport acquires (partial) symmetry protection. This effect is similar to the protection of the edge transport in time-reversal invariant topological insulators. The phase with easy axis anisotropy corresponds to the Tomonaga-Luttinger liquid with a pronounced spin-charge separation. The slow charge density wave modes have no protection against localizatioin.
description: revised version of the manuscript (accepted for publication in PRL): the detailed analysis of disorder effects has been added; the spacial scale, beyond which protection of the ideal transport is removed, has been calculated; several references have been added; 10 pages (including Supplemental Materials), 5 figure
A stone’s throw in the Neoclassical swamp of design. The Serra of Ivrea: guidelines for a restoration project

Year: 2016

description: The East residential unit built in Ivrea in 1967 by the Venetian architects Igino Cappai and Pietro Mainardis encompasses most of the set of problems related to the protection and restoration of modern architectures. Commissioned by Adriano Olivetti as a connecting element between the ancient city and the new one, which was linked to the forward-looking industrial policies, the Serra is part of an open-air museum of the Italian Modern and Modernist period. The idea is that of a building-city – to an extent close to some considerations of Le Corbusier or to more utopian visions of the Avant-Garde in architecture – where various services such as the library, cinema, bar-restaurant, swimming pool, gym and supermarket, all interlinked by a connection network, are alternated with basic residential units. The project of knowledge acquisition and restoration of this building addresses not only the problem of the obsolescence of its functions, but above all the issue of the speed of the deterioration processes of its materials.

description: The roman necropolises of the Cilicia Trachea represent an interesting case study for the investigation of archaeological heritage and its transformation. Since the nineteenth century explorations, in fact, there is confirmations of how such systems of buildings have undergone profound changes, adapting to the needs of local populations. The article aims to analyze the contemporary conditions of conservation of such structures, in order to define how such this transformation, does not concern only the past but still pursues today. To confirm this theory the essay will be focused mainly on the Cilicia Trachea and Lycia necropolises, with particular mention to the northeastern necropolis of Elaiussa Sebaste. This reality will show different constructional and architectural types of funerary buildings, in order to achieve a more complete perception of the cultural and archaeological landscape of the area.

description: The interactions between radio-loud AGN and their environments play an important role in galaxy and cluster evolution. Recent work has demonstrated fundamental differences between High and Low Excitation Radio Galaxies (HERGs and LERGs), and shown that they may have different relationships with their environments. In the Chandra Large Project ERA (Environments of Radio-loud AGN), we made the first systematic X-ray environmental study of the cluster environments of radio galaxies at a single epoch (z~0.5), and found tentative evidence for a correlation between radio luminosity and cluster X-ray luminosity. We also found that this relationship appeared to be driven by the LERG sub-population (Ineson et al. 2013). We have now repeated the analysis with a low redshift sample (z~0.1), and found strong correlations between radio luminosity and environment richness and between radio luminosity and central density for the LERGs but not for the HERGs. These results are consistent with models in which the HERGs are fuelled from accretion discs maintained from local reservoirs of gas, while LERGs are fuelled more directly by gas ingested from the intra-cluster medium. Comparing the samples, we found that although the maximum environment richness of the HERG environments is similar in both samples, there are poorer HERG environments in the z~0.1 sample than in the z~0.5 sample. We have therefore tentative evidence of evolution of the HERG environments. We found no differences between the LERG sub-samples for the two epochs, as would be expected if radio and cluster luminosity are related.

description: We consider two small cell operators deployed in the same geographical area, sharing spectrum resources from a common pool. A method is investigated to coordinate the utilization of the spectrum pool without monetary transactions and without revealing operator-specific information to other parties. For this, we construct a protocol based on asking and receiving spectrum usage favors by the operators, and keeping a book of the favors. A spectrum usage favor is exchanged between the operators if one is asking for a permission to use some of the resources from the pool on an exclusive basis, and the other is willing to accept that. As a result, the proposed method does not force an operator to take action. An operator with a high load may take spectrum usage favors from an operator that has few users to serve, and it is likely to return these favors in the future to show a cooperative spirit and maintain reciprocity. We formulate the interactions between the operators as a repeated game and determine rules to decide whether to ask or grant a favor at each stage game. We illustrate that under frequent network load variations, which are expected to be prominent in small cell deployments, both operators can attain higher user rates as compared to the case of no coordination of the resource utilization.

description: Exclusive breastfeeding is the optimal source of nutrition in the first six months of an infant’s life, ideally initiated within the first hour of life, with the addition of safe and adequate complementary feeds for up to two years and beyond1–4. There are numerous benefits of breastfeeding for the mother-baby dyad. For the baby, breastfeeding is known to provide adequate nutrition and immunity against respiratory and gastrointestinal infections, as well as other potentially life threatening diseases2,4–6. It  facilitates timely achievement of developmental milestones and long-term intellectual growth4,7. 

The main objectives of this manual are to build the competency of nurses, midwives and community health workers in Ghana in: 
•	Promoting delivery practices such as StS contact that encourage early initiation of breastfeeding
•	Supporting mothers and their families to establish and maintain lactation in a culturally sensitive manner
•	Serving as liaisons to link breastfeeding mothers to support groups/persons within their communities 

All the above are in line with Steps 4, 5 and 10 of the Ten Steps to successful breastfeeding as listed by the Baby-Friendly Health Initiative.

description: Speech emotion recognition (SER) is an essential part of human-computer interaction. In this paper, we propose an SER network based on a Graph Isomorphism Network with Weighted Multiple Aggregators (WMA-GIN), which can effectively handle the problem of information confusion when neighbour nodes' features are aggregated together in GIN structure. Moreover, a Full-Adjacent (FA) layer is adopted for alleviating the over-squashing problem, which is existed in all Graph Neural Network (GNN) structures, including GIN. Furthermore, a multi-phase attention mechanism and multi-loss training strategy are employed to avoid missing the useful emotional information in the stacked WMA-GIN layers. We evaluated the performance of our proposed WMA-GIN on the popular IEMOCAP dataset. The experimental results show that WMA-GIN outperforms other GNN-based methods and is comparable to some advanced non-graph-based methods by achieving 72.48% of weighted accuracy (WA) and 67.72% of unweighted accuracy (UA).

description: Deep learning (DL) finds rich applications in the wireless domain to improve spectrum awareness. Typically, DL models are either randomly initialized following a statistical distribution or pretrained on tasks from other domains in the form of transfer learning without accounting for the unique characteristics of wireless signals. Self-supervised learning (SSL) enables the learning of useful representations from Radio Frequency (RF) signals themselves even when only limited training data samples with labels are available. We present a self-supervised RF signal representation learning method and apply it to the automatic modulation recognition (AMR) task by specifically formulating a set of transformations to capture the wireless signal characteristics. We show that the sample efficiency (the number of labeled samples needed to achieve a certain performance) of AMR can be significantly increased (almost an order of magnitude) by learning signal representations with SSL. This translates to substantial time and cost savings. Furthermore, SSL increases the model accuracy compared to the state-of-the-art DL methods and maintains high accuracy when limited training data is available.

description: Due to the COVID-19 pandemic, the global supply chain is disrupted at an unprecedented scale under uncertain and unknown trends of labor shortage, high material prices, and changing travel or trade regulations. To stay competitive, enterprises desire agile and dynamic response strategies to quickly react to disruptions and recover supply-chain functions. Although both centralized and multi-agent approaches have been studied, their implementation requires prior knowledge of disruptions and agent-rule-based reasoning. In this paper, we introduce a model-based multi-agent framework that enables agent coordination and dynamic agent decision-making to respond to supply chain disruptions in an agile and effective manner. Through a small-scale simulated case study, we showcase the feasibility of the proposed approach under several disruption scenarios that affect a supply chain network differently, and analyze performance trade-offs between the proposed distributed and centralized methods.

INFANT AND YOUNG CHILD FEEDING IN EMERGENCIES IN NORTH CAROLINA: A REVIEW OF LITERATURE AND EMERGENCY GUIDANCE
Creators: name: Sirugo, Annamaria
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Emergencies occur frequently in the United States, so it is important to have protocols in place to best prepare for and respond to these events. Infants and young children are especially vulnerable during emergencies as they have unique nutritional needs. This paper explores emergency management policies at the federal level and in North Carolina to assess how Infant and Young Child Feeding in Emergencies (IYCF-E) is addressed. A search was conducted to identify guidance documents, and they were reviewed for IYCF-E information. Twelve federal and six state documents were included. While some documents acknowledged that infants and young children are vulnerable, few contained detailed guidance on feeding practices. More IYCF-E policies and trainings are needed to protect this vulnerable population.

description: We extend the recent gravitational decoherence analysis of Pikovski et al. to an individual mesoscopic system with internal state characterized by a coherent superposition of energy eigenstates. We express the Pikovski et al. effect directly in terms of the energy variance, and show that the interferometric visibility is bounded from below. Hence unlike collisional decoherence, the visibility does not approach zero at large times, although for a large system it can become very small.

Dimer states of Rydberg atoms on the Kagome lattice as resources for universal measurement-based quantum computation
Creators: name: Crépel, Valentin

description: We show that the quantum dimer state on the Kagome lattice, which was recently realized with high fidelity in a Rydberg quantum simulator [Semeghini et al., Science 374, 6572 (2021)], offers a sufficient resource for universal measurement-based quantum computations. In particular, we provide an efficient encoding of logical qubits in this state, and give explicit measurement sequences that implement a universal set of gates on these qubits. Since the building blocks of the proposed measurements have already been experimentally implemented, our work highlights one possible path towards promoting Rydberg simulators to universal quantum computers relying on the measurement-based model of quantum computation with currently existing technology.

description: In the interstellar medium, the amide-type molecules play an important role in the formation of the prebiotic molecules in the hot molecular cores or high-mass star formation regions. The complex amide-related molecule cyanamide (NH$_{2}$CN) is known as one of the rare interstellar molecule which has played a major role in the formation of urea (NH$_{2}$CONH$_{2}$). In this article, we presented the detection of the emission lines of cyanamide (NH$_{2}$CN) towards the hot molecular core G10.47+0.03 between the frequency range 158.49$-$160.11 GHz using the Atacama Large Millimeter/submillimeter Array (ALMA) interferometric radio telescope. The estimated column density of the emission lines of NH$_{2}$CN using the rotational diagram model was $N$(NH$_{2}$CN) = (6.60$\pm$0.1)$\times$10$^{15}$ cm$^{-2}$ with rotational temperature ($T_{rot}$) = 201.2$\pm$3.3 K. The fractional abundance of NH$_{2}$CN with respect to H$_{2}$ towards G10.47+0.03 was $f$(NH$_{2}$CN) = 5.076$\times$10$^{-8}$. Additionally, we estimated the NH$_{2}$CN/NH$_{2}$CHO abundance ratio towards the G10.47+0.03 was 0.170, which was nearly similar with NH$_{2}$CN/NH$_{2}$CHO abundance ratio towards IRAS 16293$-$2422 B and Sgr B2 (M). We found that the observed abundance of NH$_{2}$CN with respect to H$_{2}$ towards G10.47+0.03 fairly agrees with the theoretical value predicted by Garrod (2013). We also discussed the possible formation and destruction pathways of NH$_{2}$CN.

description: We develop two general methods to infer the gravitational potential of a system using steady-state tracers, i.e., tracers with a time-independent phase-space distribution. Combined with the phase-space continuity equation, the time independence implies a universal Orbital Probability Density Function (oPDF) $\mathrm{d} P(λ|{\rm orbit})\propto \mathrm{d} t$, where $λ$ is the coordinate of the particle along the orbit. The oPDF is equivalent to Jeans theorem, and is the key physical ingredient behind most dynamical modelling of steady-state tracers. In the case of a spherical potential, we develop a likelihood estimator that fits analytical potentials to the system, and a non-parametric method ("phase-mark") that reconstructs the potential profile, both assuming only the oPDF. The methods involve no extra assumptions about the tracer distribution function and can be applied to tracers with any arbitrary distribution of orbits, with possible extension to non-spherical potentials. The methods are tested on Monte Carlo samples of steady-state tracers in dark matter haloes to show that they are unbiased as well as efficient. A fully documented \textsc{C/Python} code implementing our method is freely available at a GitHub repository linked from \url{http://icc.dur.ac.uk/data/#oPDF}.

description: Disorder in a proximitizing bulk superconductor can scatter quasiparticles in a putative topological superconductor and eventually destroy the topological superconducting state. We use a scattering approach and a random-matrix calculation to estimate the disorder scattering time in a topological Josephson junction. We find that the disorder scattering rate from the bulk of the superconductor, even in the strong coupling limit, is suppressed in the ratio of Fermi momenta between the semiconductor and superconductor. This suppression of disorder scattering is accompanied by near perfect Andreev reflection at such semiconductor/superconductor interfaces, which can be used as a signature of such clean proximity effect. We also find that these results can be understood by a semiclassical estimate of scattering. We discuss limits in other systems such as the semiconductor nanowire where disorder scattering is suppressed according to similar classical estimates.

description: Biodiversity loss is a key societal challenge that humanity must address in the coming decades. Unless concrete actions are taken to stem this decline, this will lead to catastrophic effects on the Earth’s biosphere, and negatively impact human health and well-being. ELIXIR aims to address the technical challenges of biodiversity science by leveraging its suites of services and expertise to enable FAIR data analyses and management. This will enhance our understanding of life on our planet and facilitate biodiversity conservation and restoration. The newly formed ELIXIR Biodiversity Community is developing technical and community-oriented plans which include an Implementation Study to enhance ELIXIR Services application and build connections across Research Infrastructures in biodiversity. The ELIXIR Biodiversity Community will collaborate with other existing ELIXIR Communities and international consortia to develop appropriate action plans to combat biodiversity loss.

 Additionally, members of the ELIXIR Biodiversity Community are involved in externally funded projects in the space of biodiversity and agroecology. These include the Biodiversity Community Integrated Knowledge Library (BiCIKL), Biodiversity Genomics Europe (BGE), and Integrated SERvices supporting a sustainable AGROecological transition (AgroServ). BiCIKL connects infrastructures and enables researchers to access services across the lifecycle of biodiversity data. BGE is a pan-European consortium scaling up biodiversity genomics to meet the needs of tackling the biodiversity crisis. AgroServ provides customised services and facilities for interdisciplinary research on agroecosystems, aiming to promote sustainable agriculture, biodiversity preservation, and climate impact reduction. The ELIXIR Biodiversity Community will develop and strengthen these connections across the many infrastructures and services, which will be key to overcoming the complex technical challenges posed by the current heterogeneity of biodiversity data.
