description: Different simplified approaches are used to account for the non-local thermodynamic equilibrium (NLTE) effects with 3D hydrodynamical model atmospheres. In certain cases, chemical abundances are derived in 1D NLTE and corrected for the 3D effects by adding 3D-1D LTE abundance corrections (3D+NLTE approach). Alternatively, average <3D> model atmospheres are sometimes used to substitute for the full 3D hydrodynamical models. We tested whether the results obtained using these simplified schemes (i.e., 3D+NLTE, <3D> NLTE) may reproduce those derived using the full 3D NLTE computations. The tests were made using 3D hydrodynamical CO5BOLD model atmospheres of the main sequence (MS), main sequence turn-off (TO), subgiant (SGB), and red giant branch (RGB) stars, all at [M/H]=0.0 and -2.0. Our goal was to investigate the role of 3D and NLTE effects on the formation of the 670.8 nm lithium line by assessing strengths of synthetic 670.8 nm line profiles, computed using 3D/1D NLTE/LTE approaches. Our results show that Li 670.8 nm line strengths obtained using different methodologies differ only slightly in most of the models at solar metallicity. However, the line strengths predicted with the 3D NLTE and 3D+NLTE approaches become significantly different at subsolar metallicities. At [M/H]=-2.0, this may lead to (3D NLTE)-(3D+NLTE) differences in the predicted lithium abundance of ~0.46 and ~0.31 dex in the TO and RGB stars, respectively. On the other hand, NLTE line strengths computed with the average <3D> and 1D model atmospheres are similar to those obtained with the full 3D NLTE approach for MS, TO, SGB, and RGB stars, at all metallicities; 3D-<3D> and 3D-1D differences in the predicted abundances are always less than ~0.04 dex and ~0.08 dex, respectively. However, neither of the simplified approaches can reliably substitute 3D NLTE spectral synthesis when precision is required.

description: The need for nontoxic, cheap, earth-abundant catalysts, which can be sustainably produced and implemented, is essential to many processes. In this work we present unsupported iron nanoparticles as an efficient catalyst for selective acetylene hydrogenation under industrially relevant front-end conditions. Additionally, the selectivity and the activity of this catalyst can be easily moderated by the addition of carbon monoxide. The iron nanoparticles were prepared in an environment completely free of water or air using condensed ammonia at −78 °C. State of the art X-ray diffraction and scanning electron microscopy were used to determine the crystal structure, morphology, and purity. The catalyst showed stable performance over several experiments and, other than an agglomeration of the unsupported and unstabilized particles, no changes to the catalyst were detected before and after the reactions.

description: The emergent behavior of spin liquids that are born out of geometrical frustration makes them an intriguing state of matter. We show that in the quantum kagome antiferromagnet ZnCu$_3$(OH)$_6$SO$_4$ several different correlated, yet fluctuating states exist. By combining complementary local-probe techniques with neutron scattering, we discover a crossover from a critical regime into a gapless spin-liquid phase with decreasing temperature. An additional unconventional instability of the latter phase leads to a second, distinct spin-liquid state that is stabilized at the lowest temperatures. We advance such complex behavior as a feature common to different frustrated quantum magnets.
Superchaotropic nano-ion binding as a gelation motif in cellulose ether solutions
Creators: name: Hohenschutz, Max
Publisher: name: Zenodo

description: Non-ionic cellulose ethers (CEs) are an important group of biopolymers with wide application as rheology modifiers for example in cosmetics, foods and paints. Further, CE-based hydrogels, usually generated by physical hydrophobic cross-linking at elevated temperatures or synthetic strategies, are used as superabsorbers or as drug carriers in pharmaceutical products. We present here a novel and simple gelation pathway for CEs at room temperature, based on the interaction of nano-ions with the CE in water. Nanometer-sized ions (nano-ions), such as the polyoxometalate SiW12O404- (SiW, structure in Fig.1a), interact strongly with non-ionic hydrated interfaces, as provided by polymers due to a water-mediated driving force, called the chaotropic effect. In this study, we investigated the effects of superchaotropic nano-ions on cellulose ethers, such as hydroxypropylcellulose (HPC, Fig.1a). Combination of rheology, electron microscopy, small angle scattering and NMR, enabled us to show that SiW binds to HPC in the millimolar range and causes dramatic structural effects on all length scales. As a result of the SiW-binding the viscosity of HPC-solutions increased more than hundredfold, see Fig.1b and even led to gelation at HSiW-concentrations above 30 mM. These rheological effects appear due to physical nano-ion crosslinking between polymer chains and are unprecedented compared to classical additives such as salts, or ionic surfactants as exemplified for SDS, see Fig.1b. Small Angle Neutron Scattering revealed that addition of SiW causes a polyelectrolyte-like behavior of HPC, which upon screening of the electrostatic repulsion transitions into a gel. Nano-ions thus emerge as novel gelation agents. These nano-ion/CE-assemblies are promising candidates for smart hydrogels due to their UV, redox and pH sensitivity.

description: A gradient flow equation for $λϕ^{4}$ theory in $D=4$ is formulated. In this scheme the gradient flow equation is written in terms of the renormalized probe variable $Φ(t,x)$ and renormalized parameters $m^{2}$ and $λ$ in a manner analogous to the higher derivative regularization. No extra divergence is induced in the interaction of the probe variable $Φ(t,x)$ and the 4-dimensional dynamical variable $ϕ(x)$ which is defined in renormalized perturbation theory. The finiteness to all orders in perturbation theory is established by power counting argument in the context of $D+1$ dimensional field theory. This illustrates that one can formulate the gradient flow for the simple but important $λϕ^{4}$ theory in addition to the well-known Yang-Mills flow, and it shows the generality of the gradient flow for a wider class of field theory.

description: Mass determinations from gravitational lensing shear and the higher order estimator flexion are both subject to the mass sheet degeneracy. Mass sheet degeneracy refers to a transformation that leaves the reduced shear and flexion invariant. In general, this transformation can be approximated by the addition of a constant surface mass density sheet. We propose a new technique to break the mass sheet degeneracy. The method uses mass moments of the shear or flexion fields in combination with convergence information derived from number counts which exploit the magnification bias. The difference between the measured mass moments provides an estimator for the magnitude of the additive constant that is the mass-sheet. For demonstrating this, we derive relations that hold true in general for n-th order moments and show how they can be employed effectively to break the degeneracy. We investigate the detectability of this degeneracy parameter from our method and find that the degeneracy parameter can be feasibly determined from stacked galaxy-galaxy lensing data and cluster lensing data. Furthermore, we compare the signal-to-noise ratios of convergence information from number counts with shear and flexion for SIS and NFW models. We find that the combination of shear and flexion performs best on galaxy and cluster scales and the convergence information can therefore be used to break the mass sheet degeneracy without quality loss in the mass reconstruction. In summary, there is power in the combination of shear, flexion, convergence and their higher order moments. With the anticipated wealth of lensing data from upcoming and future satellite missions - EUCLID and WFIRST - this technique will be feasible.

description: Around 90 percent of greenhouse gas (GHG) emissions come from land use and energy in Colombia. The increasing GHG emissions affects the climate and water systems; therefore, the representation of the Climate-Land-Energy-Water (CLEWs) nexus is paramount. Using OSeMOSYS framework, the study develops an integrated CLEWs model for Colombia, and three scenarios are analyzed. Key takeaways are: fossil fuel resources are needed for a secure transition; electricicity and hydrogen will play a significant role in the decarbonization process; and reforestation plus efficient livestock are critical to reach carbon neutrality by mid-century. The presentation summarizes the project developed as part of the EMP-LAC 2022.
Odd-even staggering in neutron drip line nuclei

description: We have done systematic Hartree-Fock-Bogoliubov calculations in coordinate space on the one-quasi-particle energies and binding energy odd-even staggering (OES) in semi-magic nuclei with the zero-range volume, mixed and surface pairing forces in order to explore the influence of their density dependence. The odd-$N$ isotopes are calculated within the blocking scheme. The strengths for the pairing forces are determined in two schemes by fitting locally to reproduce pairing gap in $^{120}$Sn and globally to all available data on the OES of semi-magic nuclei with $Z\geq8$. In the former calculations, there is a noticeable difference between the neutron mean gaps in neutron-rich O, Ca, Ni and Sn isotopes calculated with the surface pairing and those with the mixed and volume pairing. The difference gets much smaller if the globally optimized pairing strengths are employed. The heavier Pb isotopes show the opposite trend. Moreover, large differences between the mean gap and the OES may be expected in both calculations when one goes towards the neutron drip line.

description: Introduction: Circulating Tumor Cells (CTC) have been studied in various solid tumors but clinical utility of CTC in Small Cell Lung Cancer (SCLC) remains unclear. The aim of the CTC-CPC study was to develop an EpCAM-independent CTC isolation method allowing isolation of a broader range of living CTC from SCLC and decipher their genomic and biological characteristics. Patients and methods: CTC-CPC is a monocentric prospective non-interventional study including treatment-naïve newly diagnosed SCLC. CD56+CTC were isolated from whole blood samples, at diagnosis and relapse after first-line treatment and submitted to Whole-exome-sequencing (WES). Results: Phenotypic study confirms tumor lineage and tumorigenic properties of isolated cells for the 4 patients analyzed with WES. WES of CD56+CTC and matched tumor biopsy reveal genomic alteration frequently impaired in SCLC. At diagnosis CD56+CTC were characterized by a high mutation load, a distinct mutational profile and a unique genomic, compared to match tumors biopsies. In addition to classical pathways altered in SCLC, we found new biological processes specifically affected in CD56+CTC at diagnosis. High numeration of CD56+CTC (>7/ml) at diagnosis was associated with ES-SCLC. Comparing CD56+CTC isolated at diagnosis and relapse, we identify differentially altered oncogenic pathways (e.g. DLL3 or MAPK pathway). Conclusions: We report a versatile method of CD56+CTC detection in SCLC. Numeration of CD56+CTC at diagnosis is correlated with disease extension. Isolated CD56+CTC are tumorigenic and a distinct mutational profile. We report a minimal gene set as a unique signature of CD56+CTC and identify new affected biological pathways enriched in EpCAM-independent isolated CTC in SCLC.

description: The aim of this exploratory study is to evaluate the level and methods of adaptation of small and medium sized enterprises (SMEs) to the rapid and unforeseen changes during COVID-19 era through digitization and digital transformation. Although the whole world has been affected by the COVID-19 pandemic in general, its impact on the business environment does not show a homogeneous distribution among countries, sectors, and companies. Even if the reasons are variable, the challenges and costs in front of the digitalization of SMEs all over the world are higher than that of large companies. In this context, it is aimed to reveal the knowledge and lessons learned which will form the basis for innovative, managerial, and entrepreneurial practices related to digital transformation initiatives in SMEs. In this study, a series of semi-structured interviews were conducted with the chief information officers and executives responsible for information technologies and digital transformation in three purposively selected small and medium-sized companies in the Aegean region of Türkiye, namely Bakioğlu, Norm, and Ürper respectively. Results for the decision-making processes and practices of the executives regarding the leadership characteristics of information technologies and the decisions taken regarding internal digitalization applications and adaptation to the new work environment during the covid pandemic period are presented. Within the framework of the literature, policy recommendations are provided by analyzing the interaction of their compliance with digital transformation, information management, and corporate governance principles with their strategic management and leadership characteristics. In particular, the interaction between digital maturity levels and digitalization and digital transformation practices is evaluated. In this way, we try to contribute to the advancement of the existing literature by proposing a digital maturity model taking into account the cultural, communication and technological business context.

description: In this paper, two families of trajectories on the quantum state space (QSS) originating from a synaptic-neuron model and from quantum information geometry meet together. The extended averaged Hebbian learning equation (EAHLE) on the QSS developed by the author and Yuya (Far East Journal of Applied Mathematics, vol.47, pp.149-167, 2010) from a Hebbian synaptic-neuron model is studied from a quantum-information-geometric point of view. It is shown that all the trajectories of the EAHLE are the e-geodesics, the autoparallel curves with respect to the exponential-type parallel transport, on the QSS. As a secondary outcome, an explicit representation of solution of the averaged Hebbian learning equation, the origin of the EAHLE, is derived from that of the e-geodesics on the QSS.

description: A new measure of the short form of the Physical Activity Enjoyment Scale (PACES-S), including four items, has been developed that focuses on the subjective experience of enjoyment. As validation has so far only been conducted in a youth population, the purpose of the present article was to test the psychometric properties of the measure in an adult population in three studies. In the first study (n = 1017) the results supported the unidimensional structure of the instrument (χ2 = 10.0; df = 2; p < 0.01; CFI = 0.992; RMSEA = 0.063), revealed a satisfactory level of internal consistency (ω = 0.79), and showed that the measure is invariant across gender. The results on factorial validity and internal consistency were generally supported by the second study (n = 482), which additionally showed satisfactory test–retest reliability (r = 0.73). Finally, the third study (n = 1336) also supported the factorial validity and internal consistency of the measure and additionally showed a positive correlation with physical activity (r = 0.40), thus supporting the criterion-related validity of the measure. This more economical version of PACES seems to be particularly useful for large-scale studies.
title: Catalytic CO₂ esterification with ethanol for the production of diethyl carbonate using optimized CeO₂ as catalyst
Creators: name: Buchmann, Marco

Publisher: name: UNSPECIFIED
Year: 2023

description: The direct conversion of (bio)ethanol and CO₂ is a promising route to diethyl carbonate (DEC) since both reactants are cheap and originate from renewable resources in bioethanol production. In this work we present a detailed characterization and correlation between catalyst synthesis parameters and catalytic activity of pure ceria for DEC formation. An interaction between surface acidity and basicity as well as sufficiently high specific surface area is required for optimal catalytic activity which is obtained by using urea as the precipitation agent. Catalytic activity towards DEC formation is increased when adding both cerium nitrate solution and aqueous ammonia solution in a controlled manner at a pH of 10 at 50 °C for precipitation. When combining temperature-programmed desorption (TPD) experiments and catalytic testing, mainly weak basic sites appear to be relevant for the DEC formation.

description: HCN J=1-0 emission from the long-period comet C/2013 R1 (Lovejoy) was observed from the Onsala Space Observatory on multiple occasions during the month before its perihelion passage on December 22, 2013. We report detections for seven different dates, spanning heliocentric distances (R_h) decreasing from 0.94 to 0.82 au. Estimated HCN production rates are generally higher than previously reported for the same time period, but the implied increase in production rate with heliocentric distance, Q_{HCN} proportionate to R_h^{-3.2}, represent well the overall documented increase since it was first observed at R_h=1.35. The implied mean HCN abundance relative to water in R1 Lovejoy is 0.2%. We also report on a detection of HCN with the new 3 mm receiver system at Onsala Space Observatory in comet C/2014 Q2 (Lovejoy) on January 14, 2015, when its heliocentric distance was 1.3 au. Relative to comet C/2013 R1 (Lovejoy), the HCN production rate of C/2014 Q2 (Lovejoy) was more than 5 times higher at similar heliocentric distances, and the implied HCN abundance relative to water 0.09%.

description: Quantum teleportation faithfully transfers a quantum state between distant nodes in a network, enabling revolutionary information processing applications. Here we report teleporting quantum states over a 30 km optical fiber network with the input single photon state and the EPR state prepared independently. By buffering photons in 10 km coiled optical fiber, we perform Bell state measurement after entanglement distribution. With active feed-forward operation, the average quantum state fidelity and quantum process fidelity are measured to be 0.85 and 0.77, exceeding classical limits of 0.67 and 0.5, respectively. The statistical hypothesis test shows that the probability of a classical process to predict an average state fidelity no less than the one observed in our experiment is less than 2.4E-14, confirming the quantum nature of our quantum teleportation experiment. Our experiment marks a critical step towards the realization of quantum internet in the future.

description: In quantum information science, the external control of qubits must be balanced with the extreme isolation of the qubits from the environment. Atomic qubit systems typically mitigate this balance through the use of gated laser fields that can create superpositions and entanglement between qubits. Here we propose the use of high-order optical Stark shifts from optical fields to manipulate the splitting of atomic qubits that are insensitive to other types of fields. We demonstrate a fourth-order AC Stark shift in a trapped atomic ion system that does not require extra laser power beyond that needed for other control fields. We individually address a chain of tightly-spaced trapped ions and show how these controlled shifts can produce an arbitrary product state of ten ions as well as generate site-specific magnetic field terms in a simulated spin Hamiltonian.

description: Discontinuity in density functions is of economic importance and interest. For instance, in studies on regression discontinuity designs, discontinuity in the density of a running variable suggests violation of the no-manipulation assumption. In this paper we develop estimation and testing procedures on discontinuity in densities with positive support. Our approach is built on splitting the gamma kernel (Chen, 2000) into two parts at a given (dis)continuity point and constructing two truncated kernels. The jump-size magnitude of the density at the point can be estimated nonparametrically by two kernels and a multiplicative bias correction method. The estimator is easy to implement, and its convergence properties are delivered by various approximation techniques on incomplete gamma functions. Based on the jump-size estimator, two versions of test statistics for the null of continuity at a given point are also proposed. Moreover, estimation theory of the entire density in the presence of a discontinuity point is explored. Monte Carlo simulations confirm nice finite-sample properties of the jump-size estimator and the test statistics.

Quadrupole and monopole transition properties of $0^+_2$ in Gd isotopes

description: The longstanding problem of characterization of the $0^+_2$ states in Gd isotopes is revisited by adopting the Nilsson$+$BCS mean field and the random-phase approximation. The interband electric quadrupole transition strengths varying almost two orders of magnitude are nicely reproduced at the same time as other observables. These results indicate that the $0^+_2$ states, in particular, those in lighter isotopes are well described as $β$ vibrations excited on top of deformed ground states without recourse to the shape-coexistence picture.

Bactérie hautement résistante émergente

description: Contexte. Lors de la visite de certification du groupe hospitalier mutualiste (GHM) de Grenoble, l’évaluation du risque de bactérie hautement résistante émergente (BHRe) a fait l’objet d’une remarque concernant l’insuffisante détection des patients porteurs (colonisés ou infectés) dans le service des urgences. Méthode. De nombreuses séances d’information ont été conduites, conjointement à la modification de la fiche de poste de l’infirmier d’accueil et d’orientation et à la création d’une aide informatique dans le logiciel Cristal-Net (logiciel de dossier clinique informatisé). Malgré cela, des audits du dossier du patient ont montré la persistance de l’insuffisance de détection du risque aux urgences. Le service qualité a alors proposé une campagne de communication sur les BHRe par escape game avec trois objectifs : sensibiliser le personnel à la terminologie et aux définitions, identifier les patients à risque et réaliser le prélèvement. Composé de trois étapes, briefing (5 minutes), période de jeu (20 minutes) et débriefing (5 minutes), l’escape game dure 30 minutes au total. Résultats. Après les premières démarches de sensibilisation, plusieurs audits avaient mesuré un pourcentage insuffisant de patients identifiés comme étant à risque de BHRe aux urgences : de 10% à 56% selon les évaluations. Après l’escape game, auquel seulement 15% des soignants du GHM ont participé, de nouveaux audits de dossiers de patients ont révélé un taux de détection des BHRe de 82%, et 3 mois après de 90%. Conclusion. Malgré de nombreuses séances d’information classiques, nous étions face à un échec pédagogique que l’escape game a permis de surmonter. Cette expérience plaide en faveur de l’utilisation de cette méthode qui nécessite une bonne préparation afin que les messages soient compris, retenus et appliqués sur le long terme.

description: We consider the Einstein-Maxwell system of equations in the context of isotropic coordinates for matter distributions with anisotropy in the presence of an electric field. We assume a polytropic equation of state for the matter configuration. New classes of exact solutions are generated for different polytropic indices. The model is well behaved and we can regain masses of several observed objects, in particular we obtain the mass of the star PSR J1903+327.

description: CD69 is an early leukocyte activation marker involved in the regulation of the immune response. Initial in vitro studies evaluated its function using monoclonal antibodies until knock-out mice were developed. Subsequently, four ligands for CD69 have been identified, namely galectin-1, S100A8/S100A9 complex, myosin light chains 9 and 12, and oxidized low-density lipoproteins. In addition, several molecules are laterally associated with and regulated by CD69, including calreticulin and two transmembrane receptors, sphingosine-1-phosphate receptor (S1P1) and the heterodimeric amino acid transporter complex SLC7A5-SLC3A2 (LAT1-CD98). Recently, CD69 engagement has been shown to induce the expression of the immunoregulatory receptor programmed cell death-1 (PD-1) in T cells. The molecular signaling induced by CD69 has been explored in different scenarios and cell types. This review provides a perspective on the molecular pathways, ligands and cellular functions known to be regulated by CD69.

title: Selective catalytic synthesis of short chain oxymethylene ethers by a heteropoly acid – a reaction parameter and kinetic study
Creators: name: Huth, Daniel

Publisher: name: Royal Society of Chemistry

description: Oxymethylene ethers (OME) are considered as a low-emission additive or replacement to diesel fuel. They can be synthesized by different routes based on C₁ platform chemicals in different oxidation states. The challenge is to tune the acidic catalyst for the condensation reaction to a selectivity for a certain oligomeric fraction (OME₃₋₅) for optimal fuel properties. Herein, we report the use of heteropoly acids that showed an outstanding activity and selectivity for the production of the respective OME fraction under very mild reaction conditions. Trioxane and dimethoxymethane (OME₁) were used as substrates which are both products of the methanol value-added chain. Reaction parameters such as catalyst/substrate ratio and temperature could be reduced considerably due to a high catalytic activity and selectivity. Kinetic data were obtained experimentally and modelled to estimate the reaction rate, activation energy and pre-exponential factor as a solid basis for further reaction engineering.
Genetic redundancies enhance information transfer in noisy regulatory circuits

description: Cellular decision making is based on regulatory circuits that associate signal thresholds to specific physiological actions. This transmission of information is subjected to molecular noise what can decrease its fidelity. Here, we show instead how such intrinsic noise enhances information transfer in the presence of multiple circuit copies. The result is due to the contribution of noise to the generation of autonomous responses by each copy, which are altogether associated with a common decision. Moreover, factors that correlate the responses of the redundant units (extrinsic noise or regulatory cross-talk) contribute to reduce fidelity, while those that further uncouple them (heterogeneity within the copies) can lead to stronger information gain. Overall, our study emphasizes how the interplay of signal thresholding, redundancy, and noise influences the accuracy of cellular decision making. Understanding this interplay provides a basis to explain collective cell signaling mechanisms, and to engineer robust decisions with noisy genetic circuits.

description: Since the first report in 2009, at least ten additional viruses have been identified and assigned to the proposed virus family Alternaviridae. Here we report two new mycoviruses tentatively assigned to this family, both identified as members of the fungal family Nectriaceae, which were isolated from surface-disinfected apple roots (Malus x domestica, Borkh.) affected by apple replant disease (ARD). ARD is a highly complex, worldwide-occurring disease resulting from plant reactions to a disturbed (micro)-biome and leads to high economic losses every year. The first alternavirus characterized in this study was identified in a Dactylonectria torresensis isolate. The virus was tentatively named dactylonectria torresensis alternavirus 1 (DtAV1) as the first member of the proposed new species Alternavirus dactylonectriae. The second virus was identified in an isolate of Ilyonectria robusta and was tentatively named ilyonectria robusta alternavirus 1 (IrAV1) as the first member of the proposed new species Alternavirus ilyonectriae. Full genomic sequences of the viruses were determined and are presented. Further, we found hints for putative components of a methyl transferase machinery using in silico approaches. This putative protein domain is encoded by segment 2. However, this result only establishes the basis for subsequent studies in which the function must be confirmed experimentally in vitro. Thus, this is the first study where a function is predicted to all three genomic segments within the group of the alternaviruses. These findings provide further insights into the virome of ARD-associated fungi and are therefore another brick in the wall of understanding the complexity of the disease.
