Abstract

We report measurements of radon daughters in liquid argon within the MicroBooNE time projection chamber (LArTPC). The presence of radon in MicroBooNE's 85 metric tons of active liquid argon bulk is probed with newly developed charge-based low-energy reconstruction tools and analysis techniques to detect correlated $^{214}$Bi-$^{214}$Po radioactive decays. Special datasets taken during periods of active radon doping enable new demonstrations of the calorimetric capabilities of single-phase neutrino LArTPCs for $\beta$ and $\alpha$ particles with electron-equivalent energies ranging from 0.1 to 3.0 MeV. By applying $^{214}$Bi-$^{214}$Po detection algorithms to beam-external physics data recorded over a 46-day period, no statistically significant presence of radon is detected, corresponding to a limit of $

Abstract

This paper presents multiplicity measurements of charged hadrons produced in 120 GeV/$c$ proton-carbon interactions. The measurements were made using data collected at the NA61/SHINE experiment during two different data-taking periods, with increased phase space coverage in the second configuration due to the addition of new subdetectors. Particle identification via $dE/dx$ was employed to obtain double-differential production multiplicities of $π^+$, $π^-$, $p$, $\bar{p}$, $K^+$ and $K^-$. These measurements are presented as a function of laboratory momentum in intervals of laboratory polar angle covering the range from 0 to 450 mrad. They provide crucial inputs for current and future long-baseline neutrino experiments, where they are used to estimate the initial neutrino flux.

Abstract

We have investigated the exciton fine structure in atomically thin WSe2 -based van der Waals heterostructures where the density of optical modes at the location of the semiconductor monolayer can be tuned. The energy splitting $\Delta$ between the bright and dark exciton has been measured by photoluminescence spectroscopy. We demonstrate that $\Delta$ can be tuned by a few meV, as a result of a significant Lamb shift of the optically active exciton which arises from emission and absorption of virtual photons triggered by the vacuum fluctuations of the electromagnetic field. We also measured strong variations of the bright exciton radiative linewidth, as a result of the Purcell effect. All these experimental results illustrate the strong sensitivity of the excitons to local vacuum field. We found a very good agreement with a model that demonstrates the equivalence, for our system, of a classical electrodynamical transfer matrix formalism and quantum-electrodynamical approach. The bright-dark splitting control demonstrated here should apply to any semiconductor structures.

Abstract

This paper reports measurements of two-pion Bose-Einstein (HBT) correlations in Be+Be collisions at a beam momentum of 150$A\,\mbox{GeV}/\textit{c}$ by the $\mbox{NA61/SHINE}$ experiment at the CERN SPS accelerator. The obtained momentum space correlation functions can be well described by a L\'evy distributed source model. The transverse mass dependence of the L\'evy source parameters is presented, and their possible theoretical interpretations are discussed. The results show that the L\'evy exponent $\alpha$ is approximately constant as a function of $m_{\rm{T}}$ , and far from both the Gaussian case of $\alpha = 2$ or the conjectured value at the critical endpoint, $\alpha = 0.5$. The radius scale parameter $R$ shows a slight decrease in $m_{\rm{T}}$, which can be explained as a signature of transverse flow. Finally, an approximately constant trend of the intercept parameter $\lambda$ as a function of $m_{\rm{T}}$ was observed, different from measurement results at RHIC.

Abstract

MicroBooNE is a neutrino experiment located in the Booster Neutrino Beamline (BNB) at Fermilab, which collected data from 2015 to 2021. MicroBooNE's liquid argon time projection chamber (LArTPC) is accompanied by a photon detection system consisting of 32 photomultiplier tubes used to measure the argon scintillation light and determine the timing of neutrino interactions. Analysis techniques combining light signals and reconstructed tracks are applied to achieve a neutrino interaction time resolution of $\mathcal{O}(1\,\text{ns})$. The result obtained allows MicroBooNE to access the ns neutrino pulse structure of the BNB for the first time. The timing resolution achieved will enable significant enhancement of cosmic background rejection for all neutrino analyses. Furthermore, the ns timing resolution opens new avenues to search for long-lived-particles such as heavy neutral leptons in MicroBooNE, as well as in future large LArTPC experiments, namely the SBN program and DUNE.

Abstract

The critical point of dense, strongly interacting matter is searched for at the CERN SPS in ${}^{40}$Ar + ${}^{45}$Sc collisions at 150A GeV/c. The dependence of second-order scaled factorial moments of proton multiplicity distribution on the number of subdivisions of transverse momentum space is measured. The intermittency analysis is performed using both transverse momentum and cumulative transverse momentum. For the first time, statistically independent data sets are used for each subdivision number. The obtained results do not indicate any statistically significant intermittency pattern. An upper limit on the fraction of critical proton pairs and the power of the correlation function is obtained based on a comparison with the Power-law Model developed for this purpose., Comment: 28 pages, 14 figures

Abstract

We present a measurement of $η$ production from neutrino interactions on argon with the MicroBooNE detector. The modeling of resonant neutrino interactions on argon is a critical aspect of the neutrino oscillation physics program being carried out by the DUNE and Short Baseline Neutrino programs. $η$ production in neutrino interactions provides a powerful new probe of resonant interactions, complementary to pion channels, and is particularly suited to the study of higher-order resonances beyond the $Δ(1232)$. We measure a flux-integrated cross section for neutrino-induced $η$ production on argon of $3.22 \pm 0.84 \; \textrm{(stat.)} \pm 0.86 \; \textrm{(syst.)}$ $10^{-41}{\textrm{cm}}^{2}$/nucleon. By demonstrating the successful reconstruction of the two photons resulting from $η$ production, this analysis enables a novel calibration technique for electromagnetic showers in GeV accelerator neutrino experiments.

Abstract

Mycolicibacterium phocaicum RL-HY01, a marine bacterial strain with the capability to degrade phthalic acid esters (PAEs), was isolated from Zhanjiang Bay, China. Here, the complete genome sequence of strain RL-HY01 was presented. The genome of strain RL-HY01 contains one circular chromosome of 6,064,759 bp with a G + C content of 66.93 mol%. The genome contains 5681 predicted protein-encoding genes, 57 tRNA genes, and 6 rRNA genes. Genes and gene clusters potentially involved in the metabolism of PAEs were further identified. The genome Mycolicibacterium phocaicum RL-HY01 will be helpful for advancing our understanding of the fate of PAEs in marine ecosystem.

Abstract

Simultaneous removal of nitrogen, phosphate and emerging pollutants are critical for safe reuse of wastewater, but research in this field is limited. In the present study, a novel aerobic denitrifying phosphate-accumulating bacterial strain RL-GZ01 was found to be able to utilize phthalic acid esters (PAEs) as carbon resource for cell growth. Based on 16S rRNA gene analysis, physiological and biochemical characterization, and genome-based average nucleotide identity calculation, RL-GZ01 was identified as Rhodococcus pyridinivorans. Strain RL-GZ01 showed high DEHP degradation in alkaline conditions and good tolerance of salinity and organic solvents. The degradation of DEHP by RL-GZ01 fitted well with a modified Gompertz model (R2 = 0.9985). Metabolic intermediates of DEHP were identified via UHPLC-MS/MS analysis and the catabolic pathway was proposed thereafter. Genes and gene clusters contributed to the utilization of DEHP were analyzed through genomic analysis. Analysis of KEGG nitrogen metabolism pathway indicated that nitrate and nitrite were further transformed into ammonium which was further used for the biosynthesis of L-glutamine and L-glutamate. Strain RL-GZ01 was further identified as a denitrifying phosphate accumulating organism which can accumulate phosphate by generating polyphosphate. Finally, strain RL-GZ01 was applied to municipal wastewater treatment for simultaneous removal of nitrogen, phosphate and DEHP. The removal percentages of DEHP (5 mg/L), TN (71.2 mg/L), NH4+-N (70.9 mg/L), PO43−-P (10.89 mg/L) and COD (622.4 mg/L) by strain RL-GZ01 were 89.94 %, 64.45 %, 64.94 %, 76.30 % and 63.23 % within 84 h, respectively. These demonstrated the capability of strain RL-GZ01 for the biological treatment of wastewater containing PAEs.

Abstract

This document was prepared by the MicroBooNE Collaboration using the resources of the Fermi National Accelerator Laboratory (Fermilab), a U.S. Department of Energy, Office of Science, HEP User Facility. Fermilab is managed by Fermi Research Alliance, LLC (FRA), acting under Contract No. DE-AC02-07CH11359. MicroBooNE is supported by the following: the U.S. Department of Energy, Office of Science, Offices of High Energy Physics and Nuclear Physics; the U.S. National Science Foundation; the Swiss National Science Foundation; the Science and Technology Facilities Council (STFC), part of the United Kingdom Research and Innovation; the Royal Society (United Kingdom); and the European Union’s Horizon 2020 Marie Sklodowska-Curie Actions. Additional support for the laser calibration system and cosmic ray tagger was provided by the Albert Einstein Center for Fundamental Physics, Bern, Switzerland. We also acknowledge the contributions of technical and scientific staff to the design, construction, and operation of the MicroBooNE detector as well as the contributions of past collaborators to the development of MicroBooNE analyses, without whom this work would not have been possible., We report a measurement of the energy-dependent total charged-current cross section σ(Eν) for inclusive muon neutrinos scattering on argon, as well as measurements of flux-averaged differential cross sections as a function of muon energy and hadronic energy transfer (ν). Data corresponding to 5.3×1019 protons on target of exposure were collected using the MicroBooNE liquid argon time projection chamber located in the Fermilab booster neutrino beam with a mean neutrino energy of approximately 0.8 GeV. The mapping between the true neutrino energy Eν and reconstructed neutrino energy Erecν and between the energy transfer ν and reconstructed hadronic energy Erechad are validated by comparing the data and Monte Carlo (MC) predictions. In particular, the modeling of the missing hadronic energy and its associated uncertainties are verified by a new method that compares the Erechad distributions between data and a MC prediction after constraining the reconstructed muon kinematic distributions, energy, and polar angle to those of data. The success of this validation gives confidence that the missing energy in the MicroBooNE detector is well modeled and underpins first-time measurements of both the total cross section σ(Eν) and the differential cross section dσ/dν on argon., High Energy Physics and Nuclear Physics, United Kingdom Research and Innovation, National Science Foundation, U.S. Department of Energy, Office of Science, Science and Technology Facilities Council, Royal Society, Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung

Abstract

Human temporal bone specimens are used in experiments measuring the sound transfer of the middle ear, which is the standard method used in the development of active and passive middle ear implants. Statistical analyses of these experiments usually require that the TB samples are representative of the population of non-pathological middle ears. Specifically, this means that the specimens must be mechanically well-characterized. We present an in-depth statistical analysis of 478 data sets of middle ear transfer functions (METFs) from different laboratories. The data sets are preprocessed and various contributions to the variance of the data are evaluated. We then derive a statistical range as a reference against which individual METF measurements may be validated. The range is calculated as the two-sided 95% tolerance interval at audiological frequencies. In addition, the mean and 95% confidence interval of the mean are given as references for assessing the validity of a sample group. Finally, we provide a suggested procedure for measuring METFs using the methods described herein.

Abstract

Danowhetaksa rusti Simonsen, Ware, & Archibald, new species Figure 2 Material. Holotype [MM-13418]: an isolated wing preserved in a concretion block, deposited in Museum Mors (Mo-clay Museum), collected by Henrik Madsen, October 31, 1993, Fur Stolleklint. The specimen was collected from a hardened bed within the upper 1.5 m of the Stolleklint clay near ash-layers -33 and -34. Description. Holotype wing. Arculus to distal end of pterostigma: 26.7 mm. Nodus to distal end of pterostigma: 18.9 mm. Arculus to basal end of pterostigma: 22.6 mm. Nodus to basal end of pterostigma: 14.8 mm. Width: 8.8 mm. Pterostigma dark, 5.2 mm in length, ca. 8 times longer than wide, subtends numerous cells, eight crossveins detected by preservation, surely more. Wing hyaline with transverse dark fascia, as in diagnosis, ca. 1.5 times length of pterostigma. Postnodal and postsubnodal spaces poorly preserved, but only one pair of crossveins appears aligned. IR1 very poorly preserved, origin probably zigzagged. RP2 originates 8 cells distal to subnodus. IR2 originates ca. 8/10 distance arculus to nodus, preserved part of IR2 close to linear. RP3-4 originates ca. 4/10 distance arculus to nodus, preserved part of RP3-4 close to linear. Preserved part of MA linear through fascia. Preserved part of MP linear (terminus missing). CuA linear from origin to terminus on wing margin, basal 2/3 subparallel to MA, then curving sharper to wing margin, terminates just to mid-wing beyond fascia. MA-CuA space two cells wide where CuA starts curving away, widening to at least four cells well before estimated terminus at wing margin. CuA-A space moderately well preserved, very broad, at least 5 cells wide. Quadrangle sub-trapezoid broadest distally, approximately 1.3x longer than wide. Ax0 present, synsclerotised with wing base. Arculus close to, slightly distal of Ax1. Ax2 partly preserved, ca. fifth distance arculus to nodus, just distal to quadrangle. Diagnosis. Distinguished from D. birgitteae as in its diagnosis, above. Deposit and age. Stolleklint clay, ��lst Formation, Stolleklint, Fur, Denmark; earliest Ypresian. Etymology. An eponym formed by the surname of the German paleoentomologist Jes Rust, whose extensive work has greatly increased our knowledge of mo-clay insects. Remarks. Garrouste & Nel (2015) described the monobasic Pseudostenolestidae from the latest Ypresian at Messel, Germany (Pseudostenolestes bechlyi Garrouste & Nel) and discussed ways in which it resembles the Dysagrionidae and Sieblosiidae (Cephalozygoptera). It shares a distinctive quadrangle shape with the Whetwhetaksidae, which the Dysagrionidae and Sieblosiidae also possess. Notably, the arculus of P. bechlyi is positioned near Ax1 as in the Whetwhetaksidae. In P. bechlyi, the arculus and Ax1 are opposite, while in Whetwhetaksidae Ax 1 is just basal to the arculus���slightly closer to it in Danowhetaksa than in Whetwhetaksa. The pterostigma is also long in P. bechlyi, although not as long as in the Whetwhetaksidae. Unlike the Whetwhetaksidae, however, it possesses the oblique vein ���O���, shared with the Sieblosiidae, and unlike the Whetwhetaksidae, Sieblosiidae, and Dysagrionidae, it has a very short petiole. Pseudostenolestes differs from the Zygoptera, Cephalozygoptera, and Whetwhetaksidae by its distinctive, strong vein Cuab originating at the middle posterior of the subquadrangle and directed towards the wing base, by which they assign it to the Isophlebioptera, previously only known from the Mesozoic. In most Zygoptera, Ax0 is absent or obscured by sclerotization at the wing base (Bechly 1996, and see Rehn, 2003). It is present without associated sclerotization in Whetwhetaksa and in Cephalozygoptera (Archibald et al. 2021). In D. rusti n. sp. it is present and associated with sclerotization basally, but not obscured by it., Published as part of Simonsen, Thomas J., Archibald, S.

Abstract

Danowhetaksa birgitteae Simonsen, Ware & Archibald, new species Figure 1 Material. Holotype [FUM-M-17515]: an isolated wing preserved in a concretion block; the part is missing the basalmost and apical-posterior portions, and the counterpart is missing the apical-most portion including the pterostigma; collected by Birgitte Munk, 1996, Fur Stolleklint; deposited in the Fur Museum. Description. Holotype wing. Length, arculus to distal end of pterostigma: 28.0 mm; nodus to distal end of pterostigma: 20.3 mm; arculus to base of pterostigma: max 23.4 mm; nodus to base of pterostigma: max 16.2 mm; width: 9.3 mm. Pterostigma dark (damaged basally), preserved part approximately 5 mm in length, highly elongate, at least seven times longer than wide, subtends numerous cells, five crossveins detected by preservation, surely many more. Membrane with a transverse, sub-central dark fascia, slightly narrower than length of pterostigma, otherwise hyaline. Twenty-three crossveins preserved in postnodal space, 22 in postsubnodal space, only pair aligned. IR1 very poorly preserved, origin probably slightly zigzagged, seven cells distal to origin of RP2. RP2 originates seven cells distal to subnodus. IR2 originates approximately 8.5/10 distance arculus to nodus, preserved part of IR2 close to linear. RP3-4 originates approximately 4/10 distance arculus to nodus, preserved part of RP3-4 close to linear. MA linear in basal 1/3, starts zigzagging slightly about basal margin of darkened wing band, poorly preserved beyond band. MP linear from origin to terminus at wing margin, slightly curved. CuA linear from origin to terminus on wing margin, basal 2/3 subparallel to MA, then curving sharper to wing margin, terminates basal to mid-wing. MA-CuA space two cells wide where CuA starts curving away, widening to at least six cells at wing margin. CuA-A space well preserved, very broad, at least five cells wide. Quadrangle sub-trapezoid, broadest distally, approximately 1.3 times longer than wide. Anterior wing margin not preserved basal to arculus, so Ax1 not preserved. Ax2 approximately 2/10 distance arculus to nodus, just distal to anterodistal corner of quadrangle. Diagnosis. Distinguished from D. rusti by any of: 1, RP1-2���IR2 space one cell wide, RP2���IR2 space to origin of IR1 (not preserved beyond this) [RP1-2���IR2 space becomes two cells wide ca. two cells basal origin of RP2]; 2, IR2���RP3-4 space becomes two cells wide ca. mid-way between origins of RP2, IR1 [ca. origin of IR2]; 3, seven crossveins in R1+2���IR2 space between nodus and origin of RP2 [ca. 9]. Further separated by colouration (sex unknown): narrow, dark fascia mid-wing [almost twice as wide], basally starting ca. five cells distal to nodus, includes origin of RP2, ends slightly distal to termination of CuA [anterior to R1+2 starts at nodus, posterior R1+2 just basal origin of IR2, ends on posterior margin just basal to termination of CuA, on anterior margin slightly more distal]. Deposit and age. Stolleklint clay, ��lst Formation, Stolleklint, Fur, Denmark; earliest Ypresian. Etymology. An eponym formed from the given name of Birgitte Munk, who found and donated the holotype, recognising her contribution. Remarks. Colouration is provided as supplementary in the diagnosis, as it is unknown if there are differences in colouration due to sexual dimorphism, variation between forewings and hind wings, or polymorphism in Whetwhetaksidae. Although the wing base is not preserved, we estimate CuA to terminate on the margin just over half wing length., Published as part of Simonsen, Thomas J., Archibald, S.

Abstract

We report the first measurement of $π^0$ production in neutral current (NC) interactions on argon with average neutrino energy of $\lesssim1$~GeV. We use data from the MicroBooNE detector's 85-tonne active volume liquid argon time projection chamber situated in Fermilab's Booster Neutrino Beam and exposed to $5.89\times10^{20}$ protons on target for this measurement. Measurements of NC $π^0$ events are reported for two exclusive event topologies without charged pions. Those include a topology with two photons from the decay of the $π^0$ and one proton and a topology with two photons and zero protons. Flux-averaged cross-sections for each exclusive topology and for their semi-inclusive combination are extracted (efficiency-correcting for two-plus proton final states), and the results are compared to predictions from the \textsc{genie}, \textsc{neut}, and \textsc{NuWro} neutrino event generators. We measure cross sections of $1.243\pm0.185$ (syst) $\pm0.076$ (stat), $0.444\pm0.098\pm0.047$, and $0.624\pm0.131\pm0.075$ $[10^{-38}\textrm{cm}^2/\textrm{Ar}]$ for the semi-inclusive NC$π^0$, exclusive NC$π^0$+1p, and exclusive NC$π^0$+0p processes, respectively., 16 pages, 14 figures, 2 tables

Abstract

We present the first measurement of differential cross sections for charged-current muon neutrino interactions on argon with one muon, two protons, and no pions in the final state. Such interactions leave the target nucleus in a two-particle two-hole state; these states are of great interest, but currently there is limited information about their production in neutrino-nucleus interactions. Detailed investigations of the production of two-particle two-hole states are vital to support upcoming experiments exploring the nature of the neutrino, and the development of the liquid-argon time-projection-chamber has made possible the isolation of such final states. The opening angle between the two protons, the angle between the total proton momentum and the muon, and the total transverse momentum of the final state system are sensitive to the underlying physics processes as embodied in a variety of models. Realistic initial-state momentum distributions are shown to be important in reproducing the data., Comment: To be submitted to PRL

Abstract

We present the first measurement of the cross section of Cabibbo-suppressed $Λ$ baryon production, using data collected with the MicroBooNE detector when exposed to the neutrinos from the Main Injector beam at the Fermi National Accelerator Laboratory. The data analyzed correspond to $2.2 \times 10^{20}$ protons on target of neutrino mode running and $4.9 \times 10^{20}$ protons on target of anti-neutrino mode running. An automated selection is combined with hand scanning, with the former identifying five candidate $Λ$ production events when the signal was unblinded, consistent with the GENIE prediction of $5.3 \pm 1.1$ events. Several scanners were employed, selecting between three and five events, compared with a prediction from a blinded Monte Carlo simulation study of $3.7 \pm 1.0$ events. Restricting the phase space to only include $Λ$ baryons that decay above MicroBooNE's detection thresholds, we obtain a flux averaged cross section of $2.0^{+2.2}_{-1.7} \times 10^{-40}$ cm$^2/$Ar, where statistical and systematic uncertainties are combined.

Abstract

Eos is a technology demonstrator, designed to explore the capabilities of hybrid event detection technology, leveraging both Cherenkov and scintillation light simultaneously. With a fiducial mass of four tons, Eos is designed to operate in a high-precision regime, with sufficient size to utilize time-of-flight information for full event reconstruction, flexibility to demonstrate a range of cutting edge technologies, and simplicity of design to facilitate potential future deployment at alternative sites. Results from Eos can inform the design of future neutrino detectors for both fundamental physics and nonproliferation applications. This paper describes the conceptual design and potential applications of the Eos detector.

Abstract

Accurate knowledge of electron transport properties is vital to understanding the information provided by liquid argon time projection chambers (LArTPCs). Ionization electron drift-lifetime, local electric field distortions caused by positive ion accumulation, and electron diffusion can all significantly impact the measured signal waveforms. This paper presents a measurement of the effective longitudinal electron diffusion coefficient, DL, in MicroBooNE at the nominal electric field strength of 273.9 V/cm. Historically, this measurement has been made in LArTPC prototype detectors. This represents the first measurement in a large-scale (85 tonne active volume) LArTPC operating in a neutrino beam. This is the largest dataset ever used for this measurement. Using a sample of ∼70,000 through-going cosmic ray muon tracks tagged with MicroBooNE's cosmic ray tagger system, we measure DL = 3.74+0.28 -0.29 cm2/s.

Abstract

In this article, we describe a modified implementation of Mask Region-based Convolutional Neural Networks (Mask-RCNN) for cosmic ray muon clustering in a liquid argon TPC and applied to MicroBooNE neutrino data. Our implementation of this network, called sMask-RCNN, uses sparse submanifold convolutions to increase processing speed on sparse datasets, and is compared to the original dense version in several metrics. The networks are trained to use wire readout images from the MicroBooNE liquid argon time projection chamber as input and produce individually labeled particle interactions within the image. These outputs are identified as either cosmic ray muon or electron neutrino interactions. We find that sMask-RCNN has an average pixel clustering efficiency of 85.9% compared to the dense network's average pixel clustering efficiency of 89.1%. We demonstrate the ability of sMask-RCNN used in conjunction with MicroBooNE's state-of-the-art Wire-Cell cosmic tagger to veto events containing only cosmic ray muons. The addition of sMask-RCNN to the Wire-Cell cosmic tagger removes 70% of the remaining cosmic ray muon background events at the same electron neutrino event signal efficiency. This event veto can provide 99.7% rejection of cosmic ray-only background events while maintaining an electron neutrino event-level signal efficiency of 80.1%. In addition to cosmic ray muon identification, sMask-RCNN could be used to extract features and identify different particle interaction types in other 3D-tracking detectors., 30 pages, 21 figures

Abstract

Single-cell RNA-seq (scRNA-seq) is a powerful tool for cell type identification but is not readily applicable to organisms without well-annotated reference genomes. Of the approximately 10 million animal species predicted to exist on Earth, >99.9% do not have any submitted genome assembly. To enable scRNA-seq for the vast majority of animals on the planet, here we introduce the concept of “k-mer homology,” combining biochemical synonyms in degenerate protein alphabets with uniform data subsampling via MinHash into a pipeline called Kmermaid. Implementing this pipeline enables direct detection of similar cell types across species from transcriptomic data without the need for a reference genome. Underpinning Kmermaid is the tool Orpheum, a memory-efficient method for extracting high-confidence protein-coding sequences from RNA-seq data. After validating Kmermaid using datasets from human and mouse lung, we applied Kmermaid to the Chinese horseshoe bat (Rhinolophus sinicus), where we propagated cellular compartment labels at high fidelity. Our pipeline provides a high-throughput tool that enables analyses of transcriptomic data across divergent species’ transcriptomes in a genome- and gene annotation-agnostic manner. Thus, the combination of Kmermaid and Orpheum identifies cell type-specific sequences that may be missing from genome annotations and empowers molecular cellular phenotyping for novel model organisms and species.

Abstract

Transposable DNA sequences constitute more than half of the human and mouse genomes. A large number of non-coding RNAs, named as transposon RNAs, are derived from these transposable elements. The cis-regulatory function of transposable DNA elements, such as LINE-1 and Alu has been largely explored. But the biological roles of transposon RNAs aren’t well understood. Here, investigations of RNA-chromatin interactions provide us with comprehensive evidence that specific families of transposon RNAs play roles in trans-regulation linking to the core inhibition circuitry for embryonic stem cell identity. Alternative modes of the RNA-DNA hybrid duplex and protein-recruited RNA scaffold are required for the regulatory activities of transposon RNAs. LINE-1 RNAs co-locating with KAP1 form a negative feedback loop stabilizing the transcription of LINE-1 DNA elements via RNA-DNA hybrids. In another way LINE-1 RNAs, together with the reprogramming three factors and Polycomb repressive complexes, participate in the inhibition on dozens of differentiation-relative genes.

Abstract

The acid sites of phosphorus-containing zeosils were probed through a combination of solid acid characterization, density functional theory calculations, and kinetic interrogations, establishing their weakly Brønsted acidic character. Due to the disparity in acid-site strength, P-zeosils catalyzed the probe chemistry of isopropanol dehydration slower than aluminosilicate zeolites by an order of magnitude on an active site basis. Propene selectivity during isopropanol dehydration remained 20-30% higher than that of aluminosilicates, illustrating the distinct nature of the weakly acidic phosphorus active sites that favored unimolecular dehydration routes. Regardless of the confining siliceous environment, the nature of phosphorous active sites was unchanged, indicated by identical apparent uni- and bi-molecular dehydration energy barriers. Kinetic isotope experiments with deuterated isopropanol feeds implicated an E2-type elimination to propene formation on phosphorus-containing materials. Comparison of KIEs between phosphorus-containing zeosils and aluminosilicates pointed to an unchanged isopropanol dehydration mechanism, with changes in apparent energetic barriers attributed to weaker binding on phosphorous-active sites that lead to a relatively destabilized alcohol dimer adsorbate. Both ex-situ alkylamine Hofmann elimination and in-situ pyridine titration characterization methods exhibited phosphorous acid site counts dependent on probe molecules identity and/or concentration, underpinning the limitations of extending common characterization techniques for Brønsted-acid catalysis to weakly acidic materials.

Abstract

We present the performance of a semantic segmentation network, SparseSSNet, that provides pixel-level classification of MicroBooNE data. The MicroBooNE experiment employs a liquid argon time projection chamber for the study of neutrino properties and interactions. SparseSSNet is a submanifold sparse convolutional neural network, which provides the initial machine learning based algorithm utilized in one of MicroBooNE's $\nu_e$-appearance oscillation analyses. The network is trained to categorize pixels into five classes, which are re-classified into two classes more relevant to the current analysis. The output of SparseSSNet is a key input in further analysis steps. This technique, used for the first time in liquid argon time projection chambers data and is an improvement compared to a previously used convolutional neural network, both in accuracy and computing resource utilization. The accuracy achieved on the test sample is $\geq 99\%$. For full neutrino interaction simulations, the time for processing one image is $\approx$ 0.5 sec, the memory usage is at 1 GB level, which allows utilization of most typical CPU worker machine.

Abstract

To evaluate ultrasonic features of the major salivary glands in patients with immunoglobulin G4-related sialadenitis (IgG4-RS) and to explore the differences between IgG4-RS and Sj��gren���s syndrome (SS). We conducted the study in 150 patients with IgG4-RS and 100 patients with SS. Ultrasonographic variables of the static images of major salivary glands were analysed. An experienced radiologist scored the confidence rating regarding the presence of the characteristic imaging findings using a five-grade rating system. Ultrasonography scores between IgG4-RS and SS were compared. The major salivary glands were significantly larger in patients with IgG4-RS than in the SS group. The main features of ultrasonography of the salivary glands in IgG4-RS were various hypoechoic lesions and increased colour Doppler signalling. In contrast, the major salivary glands in SS exhibited hyperechoic lines and/or spots and obscuration of the gland configuration. The scores of the summarized sonographic characteristics also showed statistically significant differences between the IgG4-RS and SS groups. This study revealed different ultrasonic features of the major salivary glands in patients with IgG4-RS and SS. The scored sonographic features were helpful in differentiating IgG4-RS from SS. Consequently, we suggest that ultrasonography of major salivary glands could be a useful imaging procedure in the evaluation of patients suspected of having IgG4-RS.

Abstract

We obtain series expansions of the $q$-scale functions of arbitrary spectrally negative L��vy processes, including processes with infinite jump activity, and use these to derive various new examples of explicit $q$-scale functions. Moreover, we study smoothness properties of the $q$-scale functions of spectrally negative L��vy processes with infinite jump activity. This complements previous results of Chan et al. [7] for spectrally negative L��vy processes with Gaussian component or bounded variation.

Abstract

We report a search for an anomalous excess of inclusive charged-current (CC) $\nu_e$ interactions using the Wire-Cell event reconstruction package in the MicroBooNE experiment, which is motivated by the previous observation of a low-energy excess (LEE) of electromagnetic events from the MiniBooNE experiment. With a single liquid argon time projection chamber detector, the measurements of $\nu_{\mu}$ CC interactions as well as $\pi^0$ interactions are used to constrain signal and background predictions of $\nu_e$ CC interactions. A data set collected from February 2016 to July 2018 corresponding to an exposure of 6.369 $\times$ 10$^{20}$ protons on target from the Booster Neutrino Beam at FNAL is analyzed. With $x$ representing an overall normalization factor and referred to as the LEE strength parameter, we select 56 fully contained $\nu_e$ CC candidates while expecting 69.6 $\pm$ 8.0 (stat.) $\pm$ 5.0 (sys.) and 103.8 $\pm$ 9.0 (stat.) $\pm$ 7.4 (sys.) candidates after constraints for the absence (eLEE$_{x=0}$) of the median signal strength derived from the MiniBooNE observation and the presence (eLEE$_{x=1}$) of that signal strength, respectively. Under a nested hypothesis test using both rate and shape information in all available channels, the best-fit $x$ is determined to be 0 (eLEE$_{x=0}$) with a 95.5% confidence level upper limit of $x$ at 0.502. Under a simple-vs-simple hypotheses test, the eLEE$_{x=1}$ hypothesis is rejected at 3.75$\sigma$, while the eLEE$_{x=0}$ hypothesis is shown to be consistent with the observation at 0.45$\sigma$. In the context of the eLEE model, the estimated 68.3% confidence interval of the $\nu_e$ hypothesis to explain the LEE observed in the MiniBooNE experiment is disfavored at a significance level of more than 2.6$\sigma$ (3.0$\sigma$) considering MiniBooNE's full (statistical) uncertainties., Comment: 40 pages, 32 figures, 6 tables

Abstract

We report results from a search for neutrino-induced neutral current (NC) resonant $Δ$(1232) baryon production followed by $Δ$ radiative decay, with a $\langle0.8\rangle$~GeV neutrino beam. Data corresponding to MicroBooNE's first three years of operations (6.80$\times$10$^{20}$ protons on target) are used to select single-photon events with one or zero protons and without charged leptons in the final state ($1\gamma1p$ and $1\gamma0p$, respectively). The background is constrained via an in-situ high-purity measurement of NC $π^0$ events, made possible via dedicated $2\gamma1p$ and $2\gamma0p$ selections. A total of 16 and 153 events are observed for the $1\gamma1p$ and $1\gamma0p$ selections, respectively, compared to a constrained background prediction of $20.5 \pm 3.65 \text{(sys.)} $ and $145.1 \pm 13.8 \text{(sys.)} $ events. The data lead to a bound on an anomalous enhancement of the normalization of NC $Δ$ radiative decay of less than $2.3$ times the predicted nominal rate for this process at the 90% confidence level (CL). The measurement disfavors a candidate photon interpretation of the MiniBooNE low-energy excess as a factor of $3.18$ times the nominal NC $Δ$ radiative decay rate at the 94.8% CL, in favor of the nominal prediction, and represents a greater than $50$-fold improvement over the world's best limit on single-photon production in NC interactions in the sub-GeV neutrino energy range, 7 pages, 7 figures, 4 tables.

Abstract

This article presents a measurement of $��_e$ interactions without pions in the final state using the MicroBooNE experiment and an investigation into the excess of low-energy electromagnetic events observed by the MiniBooNE collaboration. The measurement is performed in exclusive channels with (1$e$N$p$0$��$) and without (1$e$0$p$0$��$) visible final-state protons using 6.86$\times 10^{20}$ protons on target of data collected from the Booster Neutrino Beam at Fermilab. Events are reconstructed with the Pandora pattern recognition toolkit and selected using additional topological information from the MicroBooNE liquid argon time projection chamber. Using a goodness-of-fit test the data are found to be consistent with the predicted number of events with nominal flux and interaction models with a $p$-value of 0.098 in the two channels combined. A model based on the low-energy excess observed in MiniBooNE is introduced to quantify the strength of a possible $��_e$ excess. The analysis suggests that if an excess is present, it is not consistent with a simple scaling of the $��_e$ contribution to the flux. Combined, the 1$e$N$p$0$��$ and 1$e$0$p$0$��$ channels do not give a conclusive indication about the tested model, but separately they both disfavor the low-energy excess model at $>$90% CL. The observation in the most sensitive 1$e$N$p$0$��$ channel is below the prediction and consistent with no excess. In the less sensitive 1$e$0$p$0$��$ channel the observation at low energy is above the prediction, while overall there is agreement over the full energy spectrum.

Abstract

This article presents the reconstruction of the electromagnetic activity from electrons and photons (showers) used in the MicroBooNE deep learning-based low energy electron search. The reconstruction algorithm uses a combination of traditional and deep learning-based techniques to estimate shower energies. We validate these predictions using two $��_��$-sourced data samples: charged/neutral current interactions with final state neutral pions and charged current interactions in which the muon stops and decays within the detector producing a Michel electron. Both the neutral pion sample and Michel electron sample demonstrate agreement between data and simulation. Further, the absolute shower energy scale is shown to be consistent with the relevant physical constant of each sample: the neutral pion mass peak and the Michel energy cutoff., 27 pages; matches published version

Abstract

We give new proofs of certain equivalent conditions for the existence of generalized moments of a L��vy process $(X_t)_{t\geq 0}$; in particular, the existence of a generalized $g$-moment is equivalent to the uniform integrability of $(g(X_t))_{t\in [0,1]}$. As a consequence, certain functions of a L��vy process which are integrable and local martingales are already true martingales. Our methods extend to moments of stochastically continuous additive processes, and we give new, short proofs for the characterization of lattice distributions and the transience of L��vy processes.

Abstract

Background: There are limitations in judging the occurrence of lymph node metastasis (LNM) in hepatocellular carcinoma (HCC) before surgery. The purpose of this study was to establish a preoperative nomogram for predicting the risk of LNM in HCC and to explore its clinical utility.Methods: A total of 195 HCC patients undergoing radical hepatectomy were retrospectively analyzed. According to the presence or absence of LNM, the patients were divided into two groups, and the clinical characteristics of the two groups were compared. Risk factors for LNM were assessed based on logistic regression, and a nomogram was established. The receiver operating characteristic (ROC) curve was used to calculate area under the curve (AUC) of the logistic regression model, and the predictive accuracy of the nomogram was evaluated by the concordance index (C-index). The clinical efficacy of the nomogram was detected by decision curve analysis (DCA).Results: Logistic analysis revealed hepatitis B surface antigen (HBsAg) (HR = 3.50, 95% CI, 1.30-9.42, P = 0.013), globulin (HR = 2.46, 95% CI, 1.05-5.75, P = 0.039), neutrophil to lymphocyte ratio (NLR) (HR = 7.64, 95% CI, 3.22-18.11, P < 0.001) and tumor size (HR = 3.86, 95% CI, 1.26-11.88 P = 0.018) were independent risk factors for lymph node metastasis in HCC. The nomogram was established based on the above 4 variables, and the AUC was 0.835 (95% CI, 0.780-0.890). The calibration curve showed that the model has good predictive ability, and DCA indicates good predictive effect.Conclusions: The nomogram established by analyzing the preoperative clinical characteristics is a simple tool that can predict the risk of lymph node metastasis in HCC patients and guide clinicians to make better clinical decisions.

Abstract

We report on the first measurement of flux-integrated single differential cross sections for charged-current (CC) muon neutrino (νμ) scattering on argon with a muon and a proton in the final state, Ar40 (νμ,μp)X. The measurement was carried out using the Booster Neutrino Beam at Fermi National Accelerator Laboratory and the MicroBooNE liquid argon time projection chamber detector with an exposure of 4.59×1019 protons on target. Events are selected to enhance the contribution of CC quasielastic (CCQE) interactions. The data are reported in terms of a total cross section as well as single differential cross sections in final state muon and proton kinematics. We measure the integrated per-nucleus CCQE-like cross section (i.e., for interactions leading to a muon, one proton, and no pions above detection threshold) of (4.93±0.76stat±1.29sys)×10−38 cm2, in good agreement with theoretical calculations. The single differential cross sections are also in overall good agreement with theoretical predictions, except at very forward muon scattering angles that correspond to low-momentum-transfer events.

37. USING THE FAIRYTALE THERAPY METHOD IN THE PROCESS OF ADAPTATION OF CHILDREN WITH SPECIAL NEEDS TO THE CONDITIONS OF THE EDUCATIONAL INSTITUTION

Author

Ren L.

Abstract

The article presents the author's position regarding the adaptation process of children with special needs to the conditions of the educational institution. Typical difficulties in the adaptation process of these children are the fear of interaction with others, responding at the lessons, inability to make friends of classmates, ignoring or misunderstanding the behavior rules at school. The author argues that the efficient method for effective primary adaptation is fairytale therapy as a method that uses a fairytale form to integrate the person, develop her creative abilities, expand consciousness, and improve interaction with the world around. Article's purpose is to characterize the features of using the fairytale therapy method in the process of adaptation of children with special needs to the conditions of the educational institution, presenting its potential opportunities and methodical aspects of implementation. Methodology of research is based on the analysis and synthesis of scientific sources, observation and comparative the practices of social work with children with special needs. The theoretical and methodological basis of the work is the idea of art-therapy as a scientific and practical field of helping clients. It integrates pedagogical, psychological and artistic components (O.Kopytin, O.Tararina, B. Teplov). Scientific novelty of the article is that the author's vision of methodical aspects of using the fairytale method for primary adaptation of children with special needs to the conditions of the educational institution is offered. Conclusions. The fairytale therapy is an effective method for adaption of children with special needs to the conditions of educational institutions. Thanks to it, children can express their emotions in the form of oral or drawn, fashioned, made of sand or fabric of fairy tale plots. It is also an important element of social support for a child's by a specialist. It helps a specialist to focus on the actual tasks of the pupil’s personality development at the stage of entering a new educational space. It promotes the child's understanding of adults' concernment in his success, helps to reduce the level of negative behavior display, stabilization the emotional background, which are important for the adaptation process.

Abstract

Large Liquid Argon Time Projection Chambers (LArTPCs) are being increasingly adopted in neutrino oscillation experiments because of their superb imaging capabilities through the combination of both tracking and calorimetry in a fully active volume. Active LArTPC neutrino detectors at or near the Earth's surface, such as the MicroBooNE experiment, present a unique analysis challenge because of the large flux of cosmic-ray muons and the slow drift of ionization electrons. We present a novel Wire-Cell-based high-performance generic neutrino-detection technique implemented in MicroBooNE. The cosmic-ray background is reduced by a factor of 1.4$\times10^{5}$ resulting in a 9.7\% cosmic contamination in the selected neutrino candidate events, for visible energies greater than 200~MeV, while the neutrino signal efficiency is retained at 88.4\% for $\nu_{\mu}$ charged-current interactions in the fiducial volume in the same energy region. This significantly improved performance compared to existing reconstruction algorithms, marks a major milestone toward reaching the scientific goals of LArTPC neutrino oscillation experiments operating near the Earth's surface., Comment: 8 pages, 2 figures

Abstract

We present an analysis of MicroBooNE data with a signature of one muon, no pions, and at least one proton above a momentum threshold of 300 MeV/c (CC0$��$Np). This is the first differential cross section measurement of this topology in neutrino-argon interactions. We achieve a significantly lower proton momentum threshold than previous carbon and scintillator-based experiments. Using data collected from a total of approximately $1.6 \times 10^{20}$ protons-on-target, we measure the muon neutrino cross section for the CC0$��$Np interaction channel in argon at MicroBooNE in the Booster Neutrino Beam which has a mean energy of around 800 MeV. We present the results from a data sample with estimated efficiency of 29\% and purity of 76\% as differential cross sections in five reconstructed variables: the muon momentum and polar angle, the leading proton momentum and polar angle, and the muon-proton opening angle. We include smearing matrices that can be used to "forward-fold" theoretical predictions for comparison with these data. We compare the measured differential cross sections to a number of recent theory predictions demonstrating largely good agreement with this first-ever data set on argon., 24 pages, 43 figures, 1 table and supplemental material

Abstract

Liquid argon time projection chambers (LArTPCs) are now a standard detector technology for making accelerator neutrino measurements, due to their high material density, precise tracking, and calorimetric capabilities. An electric field (E-field) is required in such detectors to drift ionization electrons to the anode where they are collected. The E-field of a TPC is often approximated to be uniform between the anode and the cathode planes. However, significant distortions can appear from effects such as mechanical deformations, electrode failures, or the accumulation of space charge generated by cosmic rays. The latter effect is particularly relevant for detectors placed near the Earth's surface and with large drift distances and long drift time. To determine the E-field in situ, an ultraviolet (UV) laser system is installed in the MicroBooNE experiment at Fermi National Accelerator Laboratory. The purpose of this system is to provide precise measurements of the E-field, and to make it possible to correct for 3D spatial distortions due to E-field non-uniformities. Here we describe the methodology developed for deriving spatial distortions, the drift velocity and the E-field from UV-laser measurements.

Abstract

We report the first measurement of the double-differential and total muon neutrino charged current inclusive cross sections on argon at a mean neutrino energy of 0.8 GeV. Data were collected using the MicroBooNE liquid argon time projection chamber located in the Fermilab Booster neutrino beam and correspond to $1.6 \times 10^{20}$ protons on target of exposure. The measured differential cross sections are presented as a function of muon momentum, using multiple Coulomb scattering as a momentum measurement technique, and the muon angle with respect to the beam direction. We compare the measured cross sections to multiple neutrino event generators and find better agreement with those containing more complete treatment of quasielastic scattering processes at low $Q^2$. The total flux integrated cross section is measured to be $0.693 \pm 0.010 \, (\text{stat}) \pm 0.165 \, (\text{syst}) \times 10^{-38} \, \text{cm}^{2}$., 7 pages, 2 figures

Abstract

We describe a method used to calibrate the position- and time-dependent response of the MicroBooNE liquid argon time projection chamber anode wires to ionization particle energy loss. The method makes use of crossing cosmic-ray muons to partially correct anode wire signals for multiple effects as a function of time and position, including cross-connected TPC wires, space charge effects, electron attachment to impurities, diffusion, and recombination. The overall energy scale is then determined using fully-contained beam-induced muons originating and stopping in the active region of the detector. Using this method, we obtain an absolute energy scale uncertainty of 2\% in data. We use stopping protons to further refine the relation between the measured charge and the energy loss for highly-ionizing particles. This data-driven detector calibration improves both the measurement of total deposited energy and particle identification based on energy loss per unit length as a function of residual range. As an example, the proton selection efficiency is increased by 2\% after detector calibration., Comment: Accepted version

Abstract

We present results on the reconstruction of electromagnetic (EM) activity from photons produced in charged current $��_��$ interactions with final state $��^0$s. We employ a fully-automated reconstruction chain capable of identifying EM showers of $\mathcal{O}$(100) MeV energy, relying on a combination of traditional reconstruction techniques together with novel machine-learning approaches. These studies demonstrate good energy resolution, and good agreement between data and simulation, relying on the reconstructed invariant $��^0$ mass and other photon distributions for validation. The reconstruction techniques developed are applied to a selection of $��_�� + {\rm Ar} \rightarrow ��+ ��^0 + X$ candidate events to demonstrate the potential for calorimetric separation of photons from electrons and reconstruction of $��^0$ kinematics.

Abstract

© 2019 The Royal Society of Chemistry. Heterostructures, which can possess advantages of materials with different properties, have attracted enormous attention in various research fields including solar cells, photocatalysts, and optical electronic devices. In this work, a 2D/3D atomic epitaxial heterostructure with ultrathin BiOCl nanosheets and YF3:Yb, Tm octahedral crystals was fabricated via the halogen atom exchange method in the solution phase. The epitaxial heterointerface can facilitate energy transfer between BiOCl and YF3:Yb, Tm and suppress the energy quenching induced by grain boundaries. By carrying out single-particle confocal characterization, the energy upconverted by YF3:Yb, Tm is quantitatively confirmed to be transferred to ultrathin BiOCl nanosheets. As a result, YF3:Yb, Tm@BiOCl displays outstanding NIR-driven water splitting and waste-water cleaning properties. This study paves the way to fabricate 2D/3D epitaxial heterostructures, which helps to broaden the application of typical 2D materials.

Abstract

MicroBooNE is a near-surface liquid argon (LAr) time projection chamber (TPC) located at Fermilab. We measure the characterisation of muons originating from cosmic interactions in the atmosphere using both the charge collection and light readout detectors. The data is compared with the CORSIKA cosmic-ray simulation. Good agreement is found between the observation, simulation and previous results. Furthermore, the angular resolution of the reconstructed muons inside the TPC is studied in simulation., 20 pages, 14 figures

Abstract

This study is aimed to assess the role of hepatic steatosis (HS) on outcome of conversion therapy for patients with initially unresectable synchronous colorectal liver-limited metastases (CLLMs). We identified 346 patients with initially unresectable CLLMs received conversion therapy under the guidance of multidisciplinary team (MDT) in Zhongshan hospital (2013 to 2016). HS status of all patients was evaluated before the first circle of conversion therapy. The objective response rate (ORR), hepatectomy rate, predictor of conversion hepatectomy, and overall survival (OS) were compared using propensity-score matching (PSM). Predictive value of HS in conversion hepatectomy was validated with a separate cohort of 60 patients initially unresectable CLLMs who received conversion therapy (2017 to 2018). Before conversion therapy start, 108 (31.2%) patients were detected with HS status. In study set after PSM, compared with non-HS group, HS group supplied improved ORR (36.7% vs 23.9%, P = 0.020), hepatectomy rate from MDT (27.7% vs. 16.9%, P < 0.001) following conversion therapy. Multivariate analysis confirmed that HS (OR, 5.234; 95%CI, 2.398–11.423, P < 0.001), targeted therapy and transarterial chemoembolization treatment were independent predictors of hepatectomy rate. In the validation cohort, patients with HS had an improved conversion hepatectomy rate (43.7% vs. 15.9%, P = 0.038) following conversion therapy. Hepatic steatosis status could be a predictor of conversion hepatectomy in patients with synchronous colorectal liver-limited metastases. This effect appears to be independent of use of targeted therapy.

Abstract

We present double-differential measurements of antineutrino charged-current quasielastic scattering in the MINERvA detector. This study improves on a previous single-differential measurement by using updated reconstruction algorithms and interaction models and provides a complete description of observed muon kinematics in the form of a double-differential cross section with respect to muon transverse and longitudinal momentum. We include in our signal definition zero-meson final states arising from multinucleon interactions and from resonant pion production followed by pion absorption in the primary nucleus. We find that model agreement is considerably improved by a model tuned to MINERvA inclusive neutrino scattering data that incorporates nuclear effects such as weak nuclear screening and two-particle, two-hole enhancements.

Abstract

Final-state kinematic imbalances are measured in mesonless production of νμ+A→μ-+p+X in the MINERvA tracker. Initial- and final-state nuclear effects are probed using the direction of the μ - p transverse momentum imbalance and the initial-state momentum of the struck neutron. Differential cross sections are compared to predictions based on current approaches to medium modeling. These models underpredict the cross section at intermediate intranuclear momentum transfers that generally exceed the Fermi momenta. As neutrino interaction models need to correctly incorporate the effect of the nucleus in order to predict neutrino energy resolution in oscillation experiments, this result points to a region of phase space where additional cross section strength is needed in current models, and demonstrates a new technique that would be suitable for use in fine-grained liquid argon detectors where the effect of the nucleus may be even larger.
