description: Macromolecular crystallography is a well-established method in the field of structure biology and has led to the majority of known protein structures to date. After focusing on static structures, the method is now developing towards the investigation of protein dynamics through time-resolved methods. These experiments often require multiple handling steps of the sensitive protein crystals, e.g. for ligand soaking and cryo-protection. These handling steps can cause significant crystal damage, causing a decrease in data quality. Furthermore, in time-resolved experiments based on serial crystallography that use micron-sized crystals for short diffusion times of ligands, certain crystal morphologies with small solvent channels can prevent sufficient ligand diffusion. Described here is a method combining protein crystallization and data collection in a novel one-step-process. Corresponding experiments were successfully performed as a proof-of-principle using hen egg white lysozyme and crystallization times of only a few seconds. This method called JINXED (Just in time crystallization for easy structure determination) promises to result in high-quality data due the avoidance of crystal handling and has the potential to enable time-resolved experiments with crystals containing small solvent channels by adding potential ligands to the crystallization buffer, simulating traditional co-crystallization approaches.

description: Simultaneously transmitting/refracting and reflecting reconfigurable intelligent surface (STAR-RIS) has been introduced to achieve full coverage area. This paper investigate the performance of STAR-RIS assisted non-orthogonal multiple access (NOMA) networks over Rician fading channels, where the incidence signals sent by base station are reflected and transmitted to the nearby user and distant user, respectively. To evaluate the performance of STAR-RIS-NOMA networks, we derive new approximate expressions of outage probability and ergodic rate for a pair of users, in which the imperfect successive interference cancellation (ipSIC) and perfect SIC (pSIC) schemes are taken into consideration. Based on the asymptotic expressions, the diversity orders of the nearby user with ipSIC/pSIC and distant user are achieved carefully. The high signal-to-noise ratio slopes of ergodic rates for nearby user with pSIC and distant user are equal to $one$ and $zero$, respectively. In addition, the system throughput of STAR-RIS-NOMA is discussed in delay-limited and delay-tolerant modes. Simulation results are provided to verify the accuracy of the theoretical analyses and demonstrate that: 1) The outage probability of STAR-RIS-NOMA outperforms that of STAR-RIS assisted orthogonal multiple access (OMA) and conventional cooperative communication systems; 2) With the increasing of reflecting elements $K$ and Rician factor $κ$, the STAR-RIS-NOMA networks are capable of attaining the enhanced performance; and 3) The ergodic rates of STAR-RIS-NOMA are superior to that of STAR-RIS-OMA.

description: The ground state rotational spectra of 12 different isotopologues of sulphur dioxide have been refitted in a consistent way and an accurate experimental cubic force field has been determined. The experimental, semi-experimental and ab initio equilibrium structures have been calculated and found in good agreement across themselves. Different approximations limiting the accuracy are discussed. In particular, the influence of centrifugal distortion is analysed. A method is proposed to estimate the higher-order rovibrational corrections (γ-constants). Although an accurate semi-experimental structure was obtained for 19 isotopologues, it was not possible to determine and account for the breakdown of the Born–Oppenheimer approximation. Finally, it was shown that the ab initio CCSDTQ level of theory was required to obtain a good agreement with the experimental structure.

description: Let $Γ$ be a discrete countable group and let $(Ω,μ)$ be an ergodic standard Borel probability $Γ$-space. Given any non-elementary virtual dendro-morphism (that is a measurable cocycle in the automorphism group of a dendrite), we construct a unitary representation $V$ with no invariant vectors such that $\text{H}^2_b(Γ;V)$ contains a non-zero class. As a consequence, all virtual dendro-morphisms of a higher rank lattice must be elementary.

description: Background: Serratia marcescens may cause severe nosocomial infections, mostly in very low birth weight infants. Since S. marcescens exhibits by far the highest adjusted incidence rate for horizontal transmission, it can cause complex outbreak situations in neonatal intensive care units. Objective: The aim of this study was to establish a fast and highly sensitive colonization screening for prompt cohorting and barrier nursing strategies. Methods: A probe-based duplex PCR assay targeting the 16S rRNA gene of S. marcescens was developed and validated by using 36 reference strains, 14 S. marcescens outbreak- and nonoutbreak isolates, defined by epidemiological linkage and molecular typing, and applied in 1,347 clinical specimens from 505 patients. Results and Conclusions: The novel PCR assay proved to be highly specific and had an in vitro sensitivity of 100 gene copies per reaction (∼15 bacteria). It showed a similar (in laryngeal/tracheal specimens) or even higher (in rectal/stoma swabs) in vivo sensitivity in comparison to routine microbial culture and was much quicker (<24 h vs. 2 days). By combining different oligonucleotide primers, there was robust detection of genetic variants of S. marcescens strains. PCR inhibition was low (1.6%) and observed with rectal swabs only. Cohort analysis illustrated applicability of the PCR assay as a quick tool to prevent outbreak scenarios by allowing rapid decisions on cohorting and barrier nursing. In summary, this novel molecular screening for colonization by S. marcescens is specific, highly sensitive, and substantially accelerates detection.

description: The continuous spread and evolution of the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), and the rapid surge in infection cases in the coronavirus disease 2019 (COVID‐19) evoke a dire need for effective therapeutics. In this study, we explored the inhibitory potential of a library of 605 phytocompounds, selected from Indian medicinal plants with reported antiviral and anti‐inflammatory activities, against the receptor‐binding domain of spike proteins of the SARS‐CoV‐2 wild‐type and the variants of concern, including variants B.1.1.7 (Alpha), B.1.351 (Beta), P.1 (Gamma), B.1.617.2 (Delta), and B.1.1.529 (Omicron). Our approach was based on extensive molecular docking, assessment of drug‐likeness, and robust molecular dynamics simulations. We also identified promising inhibitory candidates against the host (human) proteins associated with SARS‐CoV‐2 spike activation and attachment, namely, ACE2 receptor, proteases TMPRSS2 and CTSL, and the endocytic regulator AAK1. In addition, we screened promising inhibitory compounds against the human proinflammatory cytokines‐ IL‐6, IL‐1β, TNF‐α, and IFN‐γ, that are associated with the adverse cytokine storm in COVID‐19 patients. Our analysis returned an encouraging list of promising inhibitory candidates that includes: abietatriene against the spike proteins of the SARS‐CoV‐2 wild‐type and the variants of concern; taraxerol against the human ACE2, CTSL and TNF‐α; β‐amyrin against the human TMPRSS2; cynaroside against the human AAK1 and IL‐1β; and friedelin against the human IL‐6 and IFN‐γ. Our findings provide substantial evidence for the inhibitory potential of these compounds and encourage further in vitro and in vivo studies to validate their use as safe and effective therapeutics against COVID‐19

description: We introduce in this paper new and very effective numerical methods based on neural networks for the approximation of the mean curvature flow of either oriented or non-orientable surfaces. To learn the correct interface evolution law, our neural networks are trained on phase field representations of exact evolving interfaces. The structures of the networks draw inspiration from splitting schemes used for the discretization of the Allen-Cahn equation. But when the latter approximate the mean curvature motion of oriented interfaces only, the approach we propose extends very naturally to the non-orientable case. Through a variety of examples, we show that our networks, trained only on flows of smooth and simplistic interfaces, generalize very well to more complex interfaces, either oriented or non-orientable, and possibly with singularities. Furthermore, they can be coupled easily with additional constraints which opens the way to various applications illustrating the flexibility and effectiveness of our approach: mean curvature flows with volume constraint, multiphase mean curvature flows, numerical approximation of Steiner trees or minimal surfaces.

description: One of the most fundamental results in quantum information theory is that no measurement can perfectly discriminate between non-orthogonal quantum states. In this work, we investigate quantum advantages for discrimination tasks over noncontextual theories by considering a maximum confidence measurement that unifies different strategies of quantum state discrimination, including minimum-error and unambiguous discrimination. We first show that maximum confidence discrimination, as well as unambiguous discrimination, contains contextual advantages. We then consider a semi-device independent scenario of certifying maximum confidence measurement. The scenario naturally contains undetected events, making it a natural setting to explore maximum confidence measurements. We show that the certified maximum confidence in quantum theory also contains contextual advantages. Our results establish how the advantages of quantum theory over a classical model may appear in a realistic scenario of a discrimination task.

description: In this note we present a formula for the equivariant index of the cohomological complex obtained from localization of $\mathcal{N}=2$ SYM on simply-connected compact four-manifolds with a $T^2$-action. Knowledge of said index is essential to compute the perturbative part of the partition function for the theory. In the topologically twisted case, the complex is elliptic and its index can be computed in a standard way using the Atiyah-Bott localization formula. Recently, a framework for more general types of twisting, so-called cohomological twisting, was introduced for which the complex turns out to be only transversally elliptic. While the index of such a complex has been computed for some cases where the manifold can be lifted to a Sasakian $S^1$-fibration in five dimensions, a general four-dimensional treatment was still lacking. We provide a formal, purely four-dimensional treatment of the cohomological complex, showing that the Laplacian part can be globally split off while the remaining part can be trivialized uniquely in the group-direction. This ultimately produces a simple formula for the index applicable for any compact simply-connected four-manifold. Finally, the index formula is applied to examples on $S^4$, $\mathbb{CP}^2$ and $\mathbb{F}^1$. For the latter, we use the result to compute the perturbative partition function.

description: We report high resolution infrared spectra in the CF stretching fundamental ranges of trifluoromethylacetylene (CF3−C≡C-H, 3,3,3-trifluoropropyne) and of tetrafluoromethane (CF4, R14, PCF-14, Halocarbon14). For the experiments a diode laser setup combined with a supersonic jet expansion is described, achieving approximate rotational temperatures between 5 and 10 K for CF4, using a pulsed slit nozzle providing effective optical path lengths of 3 to 4 cm in a single pass. Slightly higher rotational temperatures (near 30 K) for CF3CCH greatly simplify the rotational-vibrational structure of the spectra for this molecule, for which we report also high resolution Fourier transform (FTIR) spectra at room temperature with nearly Doppler limited resolution (instrumental bandwidth 0.001 cm−1) using the Zürich prototype spectrometer ZP 2001 (Bruker IFS125). The analysis of the CF3-symmetric stretching (A1) fundamental ν3 provides accurate spectroscopic parameters of the ground and excited vibrational states with a band centre ν~3 = (1253.4985 ± 0.0015) cm−1 from a least squares adjustment to more than 1100 line data with a root mean square deviation drms less than 0.0003 cm−1. The low temperature spectra of the degenerate (F2) ν3 fundamental of CF4 show a very simple structure of line clusters which can be analysed with an approximate term formula. The spectra are essentially instrument limited with a smallest effective line width near 0.002 cm−1. The assignment of the P(1) line at 1283.33693 cm−1 in the supersonic jet spectra (about 10 K) provides a band centre in terms of the vibrational energy of the (v3 = 1, J = 0, F1− (3F2+)) level at (1283.7193 ± 0.002) cm−1. Also the assignment of the isolated R(0) line at 1283.48420 cm−1 provides the energy of the well defined (v3 = 1, J' = 1, A2+ (5A1+)) level. The results are discussed in relation to the data from the HITRAN tables, earlier FTIR data, and new frequency comb based data for CF4. We also discuss possible studies of nuclear spin symmetry conservation in CF4, for which lower temperatures would be required, and a concept to study parity violation in CF4 by a level crossing experiment using molecular beam spectroscopy.

description: We use the multiscale entanglement renormalisation ansatz (MERA) to numerically investigate three critical quantum spin chains with Z_2 x Z_2 on-site symmetry: a staggered XXZ model, a transverse field cluster model, and the quantum Ashkin-Teller model. All three models possess a continuous one-parameter family of critical points. Along this critical line, the thermodynamic limit of these models is expected to be described by classes of c=1 conformal field theories (CFTs) of two possible types: the S^1 free boson and its Z_2-orbifold. Our numerics using MERA with explicitly enforced Z_2 x Z_2 symmetry allow us to extract conformal data for each model, with strong evidence supporting the identification of the staggered XXZ model and critical transverse field cluster model with the S^1 boson CFT, and the Ashkin-Teller model with the Z_2-orbifold boson CFT. Our first two models describe the phase transitions between symmetry protected topologically ordered phases and trivial phases, which lie outside the usual Landau-Ginsburg-Wilson paradigm of symmetry breaking. Our results show that a range of critical theories can arise at the boundary of a single symmetry protected phase.

description: For airlines to deliver quality services, they must understand customers’ expectations. However, the variations of airline service attribute lists in the available literature suggests a lack of consensus among industry players (airline managers, travel agency managers and airline customers) regarding what constitutes a quality airline service. From a marketing concept point of view, the customer's perspective should inform the design and delivery of airline services. Based on this view, this paper seeks to identify the most important airline service attributes that influence airline preference and choice. A survey is conducted using a questionnaire with fifty-five airline service items. Respondents are asked to rate the importance of these items on a five-point Likert scale. Collected data are subjected to an exploratory factor analysis, which retains ten latent factors as airline service attributes. The ten airline service attributes are then ranked using the mean scores and Airline reliability; Booking and check-in services; Staff courtesy, competence and responsiveness; Luggage handling and Cabin features and experiences were identified as the five most important attributes. The results suggest that airlines need to pay attention and channel resources to these attributes in order to meet customer expectations.

description: Optical Projection Tomography (OPT) is a powerful tool for 3D imaging of mesoscopic samples, thus of great importance to image whole organs for the study of various disease models in life sciences. OPT is able to achieve resolution at a few tens of microns over a large sample volume of several cubic centimeters. However, the reconstructed OPT images often suffer from artifacts caused by different kinds of physical miscalibration. This work focuses on the refractive index (RI) mismatch between the rotating object and the surrounding medium. We derive a 3D cone beam forward model to approximate the effect of RI mismatch and implement a fast and efficient reconstruction method to correct the induced seagull-shaped artifacts on experimental images of fluorescent beads.

description: The generation of photon pairs in single quantum dots is based on a process that is, in its nature, deterministic. However, an efficient extraction of these photon pairs from a high-index semiconductor host material requires engineering of the photonic environment. We report on a micropillar-based device featuring an extraction efficiency of 69.4(10)$\%$ that is achieved by harnessing a broadband operation suitable for extraction of photon pairs emitted from a single quantum dot. Opposing the approaches that rely solely on Purcell enhancement to realize the enhancement of the extraction efficiency, our solution exploits a suppression of the emission into the modes other than the cavity mode. Our technological implementation requires modest fabrication effort enabling higher device yields that can be scaled up to meet the growing needs of quantum technologies. Furthermore, the design of the device can be further optimized to allow for an extraction efficiency of 85$\%$.

description: In Computational Literary Studies (CLS), several procedures for thematic analysis have been adapted from NLP and Computer Science. Among these procedures, topic modeling is the most prominent and popular technique. We maintain, however, that this procedure is used only in the context of exploration up to date, but not in the context of justification. When we seek to prove assumptions concerning the correlation between genres, methods of computational text analysis have to be set up in research environments of justification, i.e. in environments of hypothesis testing. We provide a holistic model of validation and conceptual disambiguation of the notion of aboutness as sujet, fabula, and theme, and discuss essential methodological requirements for hypothesis-based analysis. As we maintain that validation has to be performed for individual tasks respectively, we shall perform empirical validation of topic modeling based on a new corpus of German novellas and comprehensive annotations and draw hypothetical generalizations on the applicability of topic modeling for analyzing aboutness in the domain of narrative fiction.

The data reveals two narrow structures at $E_γ= 1.036$ and $E_γ=1.119$ GeV. They may signal narrow resonances with masses near $1.68$ and $1.72$ GeV, or they may be generated by the sub-threshold $KΛ$ and $ωp$ production. Their decisive identification requires additional theoretical and experimental efforts.

description: The staple of human intelligence is the capability of acquiring knowledge in a continuous fashion. In stark contrast, Deep Networks forget catastrophically and, for this reason, the sub-field of Class-Incremental Continual Learning fosters methods that learn a sequence of tasks incrementally, blending sequentially-gained knowledge into a comprehensive prediction. This work aims at assessing and overcoming the pitfalls of our previous proposal Dark Experience Replay (DER), a simple and effective approach that combines rehearsal and Knowledge Distillation. Inspired by the way our minds constantly rewrite past recollections and set expectations for the future, we endow our model with the abilities to i) revise its replay memory to welcome novel information regarding past data ii) pave the way for learning yet unseen classes. We show that the application of these strategies leads to remarkable improvements; indeed, the resulting method - termed eXtended-DER (X-DER) - outperforms the state of the art on both standard benchmarks (such as CIFAR-100 and miniImagenet) and a novel one here introduced. To gain a better understanding, we further provide extensive ablation studies that corroborate and extend the findings of our previous research (e.g. the value of Knowledge Distillation and flatter minima in continual learning setups).

description: A homogeneous and isotropic cosmological model with a positive cosmological constant is considered. The matter sector is given by a massless scalar field, which can be used as an internal time to deparametrize the theory. The idea is to study and compare the evolutions of a quantum and a classical probability distribution by performing a decomposition of both distributions in their corresponding moments. For the numerical analysis an initial peaked Gaussian state in the volume will be chosen. Furthermore, in order to check the robustness of certain results, as initial state both a slightly deformed Gaussian, as well as another completely different state, will also be studied. Differences and similarities between classical and quantum moments are pointed out. In particular, for a subset of moments classical and quantum evolutions are quite similar, but certain variables show remarkable differences.

description: Computational poetics encompasses the wide range of challenges implicit in analyzing and generating poetry – in all of its many forms – through computational techniques and frameworks. In this paper, we build on a nascent body of work that has proposed the use of the limerick as a ‘model organism’ for computational poetics, and in particular the use of Benchmarked Poetic Minimal Pairs (BPoMP) as an investigative framework, especially for the evaluation of the poetic abilities of deep learning language models. To that end, we include results for two new BPoMP tasks of interest for limerick analysis – the word deletion task and the limerick completion tasks. We include a release of a data set for the deletion task. We also offer up a suite of an additional ten BPoMP challenges whose precise formulations still require detail.
Stable vs. unstable accretion: How to spin down a classical T Tauri star?

description: Classical T Tauri stars (CTTs) are young (a few Myr old) magnetized stellar objects that are accreting from their surroundings disks. Previous numerical studies have demonstrated that accretion in CTTs occurs in two different states: stable or unstable. In this talk, I will present 3D MHD simulations of star-disk interaction (SDI) highlighting that stable accretion is a key ingredient for a stellar spin-down and thus, it can explain the observed slow rotation of CTTs. In our runs, stable accretion is achieved when the truncation radius coincides with the corotation radius of the system. Such configurations, in axisymmetric models, lead to a propeller phase that is accompanied by an extreme mass-accretion-rate variability. I will show that 3D models are able to produce net torques that efficiently brake the stellar rotation (with a spin-down timescale of less than one Myr) and $\dot{M}_{acc}$ variations that agree well with observations. Unlike earlier works, I will further attempt to establish a clear correlation between stellar spin-down/-up and stable/unstable accretion, respectively, using synthetic light curves (periodic vs. non-periodic). Finally, I will provide precise torque measurements of the flow components arising from SDI and discuss how the magnetic torques counteract the stellar spin-up due to accretion.

Standard Vs Uniform Binary Search and Their Variants in Learned Static Indexing: The Case of the Searching on Sorted Data Benchmarking Software Platform

description: Learned Indexes are a novel approach to search in a sorted table. A model is used to predict an interval in which to search into and a Binary Search routine is used to finalize the search. They are quite effective. For the final stage, usually, the lower_bound routine of the Standard C++ library is used, although this is more of a natural choice rather than a requirement. However, recent studies, that do not use Machine Learning predictions, indicate that other implementations of Binary Search or variants, namely k-ary Search, are better suited to take advantage of the features offered by modern computer architectures. With the use of the Searching on Sorted Sets SOSD Learned Indexing benchmarking software, we investigate how to choose a Search routine for the final stage of searching in a Learned Index. Our results provide indications that better choices than the lower_bound routine can be made. We also highlight how such a choice may be dependent on the computer architecture that is to be used. Overall, our findings provide new and much-needed guidelines for the selection of the Search routine within the Learned Indexing framework.

description: The green synthesis of nanoparticles has been a vital aspect in the search for novel antimicrobial agents. This research aimed at biosynthesis, characterization and preliminary evaluation of the antibacterial properties of silver nanoparticles (AgNPs) from the back extract of Annona senegalensisis. The bark of Annona senegalensis was scraped from the stem, washed, air-dried, pulverised and extracted. Four millilitre (4 ml) of the extract was pipetted into 36 mL (36 ml) of silver nitrate solution (5 mM AgNO3) in a conical flask. The resulting solution was subjected to magnetic stirring at room temperature (28 ?C ? 2) till AgNPs were formed. The synthesized AgNPs were filtered, washed with deionized water and dried in oven at 40 ?C. Fourier transform infrared (FTIR) analysis was carried out on the synthesized AgNPs. The AgNPs synthesized was also characterized with UV–visible spectrophotometer (UV), scanning electron microscope (SEM), transmission electron microscopy (TEM), energy?dispersive X-ray (EDX) spectroscopy to ascertain the physico-chemical and morphological properties of the AgNPs. The antimicrobial investigation was carried out following standard method. The observation of colour change (pale yellow to dark brown) during the synthesis and maximum absorbance at wavelength 431.19 nm in the UV spectrum confirmed the formation of AgNPs. The FTIR analysis showed that the biomolecules responsible for the reduction of silver ion contain O–H functional groups. The electron microscopy studies indicated that the AgNPS are spherical in shape with nanoparticles sizes of 11–24.76 nm. EDX analysis showed that the AgNPs contain high amount of silver and few other elements. The antimicrobial study showed high zones of inhibition 22.75–33.75 against tested bacteria. The simplicity of the synthesis of AgNPs from the extract of the stem bark of Annona senegalensisis and relatively high zones of inhibitions shown by the AgNPs are strong evidences of the possible application of Annona senegalensisis in the synthesis of novel therapeutic agent against infections from bacteria and fungi.
