description: Bayesian neural networks allow us to keep track of uncertainties, for example in top tagging, by learning a tagger output together with an error band. We illustrate the main features of Bayesian versions of established deep-learning taggers. We show how they capture statistical uncertainties from finite training samples, systematics related to the jet energy scale, and stability issues through pile-up. Altogether, Bayesian networks offer many new handles to understand and control deep learning at the LHC without introducing a visible prior effect and without compromising the network performance.

description: We present the first detailed hydrodynamic simulation of a superoutburst to incorporate the full tidal potential of a binary system. A two-dimensional smoothed particle hydrodynamics code is used to simulate a superoutburst in a binary with the parameters of the SU UMa system Z Chamaeleontis. The simulated light curves shows all the features observed in such systems. Analysis of the mass flux through the disc and the growth rate of the superhumps and disc eccentricity show that the superoutburst-superhump phenomenon is a direct result of tidal instability. No enhanced mass transfer from the secondary is required to initiate or sustain these phenomena. Comparisons of superoutbursts with normal outbursts are made and we show that the model can be reconciled with the behavior of U Geminorum type dwarf novae, which show no superoutbursts.

description: Instability of perovskite photovoltaics is still a topic which is currently under intense debate, especially the role of water environment. Unraveling the mechanism of this instability is urgent to enable practical application of perovskite solar cells. Here, ab initio metadynamics is employed to investigate the initial phase of a dissolution process of CH$_3$NH$_3$PbI$_3$ (MAPbI$_3$) in explicit water. It is found that the initial dissolution of MAPbI$_3$ is a complex multi-step process triggered by the departure of I$^-$ ion from the CH$_3$NH$_3$I-terminated surface. Reconstruction of the free energy landscape indicates a low energy barrier for water dissolution of MAPbI$_3$. In addition, we propose a two-step thermodynamic cycle for MAPbI$_3$ dissolution in water at a finite concentration that renders a spontaneity of the dissolution process. The low energy barrier for the initial dissolution step and the spontaneous nature of MAPbI$_3$ dissolution in water explain why the water immediately destroys pristine MAPbI$_3$. The dissolution thermodynamics of all-inorganic CsPbI$_3$ perovskite is also analyzed for comparison. Hydration enthalpies and entropies of aqueous ions play an important role for the dissolution process. Our findings provide a comprehensive understanding to the current debate on water instability of MAPbI$_3$.

description: A new series of biologically active 3-[(2R*)-2-[(2S*)-6-fluoro-3,4-dihydro-2H-chromen-2-yl]-2-hydroxyethyl]-urea/thiourea derivatives (1) have been designed and synthesized in four steps from 6-fluoro-3,4-dihydro-2-(oxiran-2-yl)-2H-chromene (2). The structures of newly synthesized compounds (1a–j) were confirmed by 1H, 13C NMR, and HRMS. The major advantages of the present article include the development of an efficient eluent system for good separation of diastereomers (2a and 2b) with high yields and synthesis of (R*)-2-(benzylamino)-1-((S*)-6-fluoro-3,4-dihydro-2H-chromen-2-yl)ethanol (3) in high yields (87%) from epoxide (2a) through new reaction conditions. The synthesized compounds (1a–j) exhibited moderate to excellent antimicrobial activities against both bacterial strains (gram + Ve and gram –Ve strains) and fungal strains. Among the tested compounds, promising lead compounds were identified (compounds 1a and 1d against bacterial strains and compound 1h and 1j against fungal strains) and their antimicrobial activities are comparable with the reference standard.

Creators: name: Shabnam Moledina
Publisher: name: Zenodo
Year: 2021

description: Introduction: Palliative and hospice care nurses provide specialized healthcare services for patients at the end of life (EOL) and support their families during this time. Positive communication skills are paramount in the delivery of quality care at EOL. Studies have shown that nurses’ knowledge of best communication strategies and their self- efficacy in effectively communicating with patients and families improved after participating in End-of-Life Nursing Education Consortium (ELNEC) and COMFORT communication training. Aim: The aim of this project was to evaluate a training program based on ELNEC and COMFORT communication to improve communication skills of nurses working in a community hospice care setting. Methods: Nine nurses employed at a community care hospice center in Southern California participated in an ELNEC focused educational training program involving two, two-hour sessions. A pre and posttest design was used. Knowledge of EOL communication strategies and self-efficacy in communications skills were assessed, and a program evaluation was conducted. Results: Two- tailed, paired sample T-test analyses were conducted. Pre and posttest results related to the communication training showed significant increases in knowledge of EOL (P< .001) and participant’s self-efficacy (P = .009). Participants’ evaluation of the program indicated a high level of satisfaction and perceived improved confidence in their communicating skills. They also reported practicing communication skills through role play was beneficial. Conclusion: Training using the ELNEC communication Module 6 and COMFORT communication curriculum was an effective teaching strategy that improved nurses’ knowledge, skill, and confidence about communicating with patients and their families during hospice/palliative and EOL care. The use of ELNEC training modules are recommended as the standard for educational preparation of hospice care nurses.

description: Within the framework of the generalized Landau-de Gennes theory, we identify a $Q$-tensor-based energy that reduces to the four-constant Oseen-Frank energy when it is considered over orientable uniaxial nematic states. Although the commonly considered version of the Landau-de Gennes theory has an elastic contribution that is at most cubic in components of the $Q$-tensor and their derivatives, the alternative offered here is quartic in these variables. One clear advantage of our approach over the cubic theory is that the associated minimization problem is well-posed for a significantly wider choice of elastic constants. In particular, quartic energy can be used to model nematic-to-isotropic phase transitions for highly disparate elastic constants. In addition to proving well-posedness of the proposed version of the Landau-de Gennes theory, we establish a rigorous connection between this theory and its Oseen-Frank counterpart via a $Γ$-convergence argument in the limit of vanishing nematic correlation length. We also prove strong convergence of the associated minimizers.

description: Proton-antiproton annihilation into two pions and three pions is studied in a baryon-exchange model. Annihilation diagrams involving nucleon as well as Delta-resonance exchanges are included consistently in the two- and three-pion channels. Effects from the initial-state interaction are fully taken into account. A comparison of the influence of the Delta exchange on the considered annihilation channels is made and reveals that its importance for three-pion annihilation is strongly reduced as compared to two-pion annihilation. It is found that annihilation into three uncorrelated pions can yield up to 10 % of the total experimentally observed three-pion annihilation cross section.

description: We describe a software package called VPLanet that simulates fundamental aspects of planetary system evolution over Gyr timescales, with a focus on investigating habitable worlds. In this initial release, eleven physics modules are included that model internal, atmospheric, rotational, orbital, stellar, and galactic processes. Many of these modules can be coupled simultaneously to simulate the evolution of terrestrial planets, gaseous planets, and stars. The code is validated by reproducing a selection of observations and past results. VPLanet is written in C and designed so that the user can choose the physics modules to apply to an individual object at runtime without recompiling, i.e., a single executable can simulate the diverse phenomena that are relevant to a wide range of planetary and stellar systems. This feature is enabled by matrices and vectors of function pointers that are dynamically allocated and populated based on user input. The speed and modularity of VPLanet enables large parameter sweeps and the versatility to add/remove physical phenomena to assess their importance. VPLanet is publicly available from a repository that contains extensive documentation, numerous examples, Python scripts for plotting and data management, and infrastructure for community input and future development.

description: We study the electronic structure, magnetic state, and phase stability of paramagnetic BiNiO$_3$ near a pressure-induced Mott insulator-to-metal transition (MIT) by employing a combination of density functional and dynamical mean-field theory. We obtain that BiNiO$_3$ exhibits an anomalous negative-charge-transfer insulating state, characterized by charge disproportionation of the Bi $6s$ states, with Ni$^{2+}$ ions. Upon a compression of the lattice volume by $\sim$4.8\%, BiNiO$_3$ is found to make a Mott MIT, accompanied by the change of crystal structure from triclinic $P\bar{1}$ to orthorhombic $Pbnm$. The pressure-induced MIT is associated with the melting of charge disproportionation of the Bi ions, caused by a charge transfer between the Bi $6s$ and O $2p$ states. The Ni sites remain to be Ni$^{2+}$ across the MIT, which is incompatible with the valence-skipping Ni$^{2+}$/Ni$^{3+}$ model. Our results suggest that the pressure-induced change of the crystal structure drives the MIT in BiNiO$_3$.

description: In the period from 1950 to 1990, the Taiwanese economy, which has become famous for its rapid growth, underwent many dramatic changes. This thesis examines the role of the small and medium sized export trading companies (SMETCs) in the transition of Taiwan's economy under its export-oriented policies. Taiwan's SMETCs not only acted as intermediaries between manufacturers and international buyers in the export channels but also provided strategic information relating to the global market and acted as an agent in changing the focus and direction of Taiwanese industries. They exercised significant power, leading Taiwanese industries into successive stages of globalization. Furthermore, SMETCs also pushed Taiwan into achieving both 'scale economies' and 'scope economies'. Taiwan's SMETCs provided the logistics for the famous Taiwanese subcontract domestic production networks. Under this manufacturing system, SMETCs helped to develop Taiwan's economy first from the stage of agricultural and processed products into labour-intensive light industry, then into the skilled labour-intensive industries of electronic and electrical assemblies, and finally into the capital-intensive high technology industries. The SMETCs have played a significant role in the staged development of the Taiwanese economy.

description: We investigate the role of ram pressure stripping in the Virgo cluster using N-body simulations. Radial orbits within the Virgo cluster's gravitational potential are modeled and analyzed with respect to ram pressure stripping. The N-body model consists of 10000 gas cloud complexes which can have inelastic collisions. Ram pressure is modeled as an additional acceleration on the clouds located at the surface of the gas distribution in the direction of the galaxy's motion within the cluster. We made several simulations changing the orbital parameters in order to recover different stripping scenarios using realistic temporal ram pressure profiles. We investigate systematically the influence of the inclination angle between the disk and the orbital plane of the galaxy on the gas dynamics. We show that ram pressure can lead to a temporary increase of the central gas surface density. In some cases a considerable part of the total atomic gas mass (several 10^8 M_solar) can fall back onto the galactic disk after the stripping event. A quantitative relation between the orbit parameters and the resulting HI deficiency is derived containing explicitly the inclination angle between the disk and the orbital plane. The comparison between existing HI observations and the results of our simulations shows that the HI deficiency depends strongly on galaxy orbits. It is concluded that the scenario where ram pressure stripping is responsible for the observed HI deficiency is consistent with all HI 21cm observations in the Virgo cluster.

description: Typical nanoparticle-based plasmonic index sensors detect the spectral shift of localized surface plasmon resonance (LSPR) upon the change of environmental index. Therefore, they require broadband illumination and spectrometers. The sensitivity and flexibility of nanoparticle-based index sensors are usually limited because LSPR peaks are usually broad and the spectral position cannot be freely designed. Here, we present a fully designable index sensing platform using a plasmonic Doppler grating (PDG), which provides broadband and azimuthal angle-dependent grating periodicities. Different from LSPR, the PDG index sensor is based on the momentum matching between photons and surface plasmons via the lattice momentum of the grating. Therefore, index change is translated into the variation of in-plane azimuthal angle for photon-to-plasmon coupling, which manifests as directly observable dark bands in the reflection image. The PDG can be freely designed to optimally match the range of index variation for specific applications. In this work, we demonstrate PDG index sensors for large (n = 1.00 to 1.52) and small index variation (n = 1.3330 to 1.3650). The tiny and nonlinear index change of water-ethanol mixture has been clearly observed and accurately quantified. Since the PDG is a dispersive device, it enables on-site and single-color index sensing without a spectrometer and provides a promising spectroscopic platform for on-chip analytical applications.

description: The aim of this study was to characterise phenolic compounds of olive flower obtained from Olive tree cultivar Chemlali and to investigate their anticancer effect on MCF-7 cells. Phenolic characterisation was determined using LC/MS-MS. Cytotoxicity of the extract was determined using MTT. Biochemical markers of apoptosis were evaluated by immunoblotting. Our results showed that olive flower contained significant amounts of phenolic compounds mainly flavonoids, secoiridoids and simple phenols. Furthermore, the phenolic extract exerted a significant reduction in MCF-7 cell viability (EC50 values equal to 220.8 μg/ml). Western blot analysis revealed the presence of the cleaved forms of Parp-1. The DAPI staining analysis demonstrated a significant reduction in the number of cells and a considerable change in the morphology of the treated cells. In conclusion, Olea europaea. L flower contained great amounts of different bio-phenols able to reduce the proliferative activity of breast cancer MCF-7 cells by the induction of apoptosis.

description: We present high resolution X-ray observations of the narrow line radio galaxy PKS 1138-262 at z = 2.156 with the ACIS-S detector on the Chandra observatory. These observations show that the X-ray emission from 1138-262 is dominated by emission from the AGN with a (rest frame) 2 to 10 keV luminosity of 4x10^{45} erg/s. The relative X-ray and radio properties of the AGN in 1138-262 are similar to those seen for the AGN in the archetype powerful radio galaxy Cygnus A. Between 10% and 25% (depending on energy) of the X-ray emission from 1138--262 is spatially extended on scales of 10'' to 20''. The extended X-ray emission is elongated, with a major axis aligned with that of the radio source. While the X-ray and radio emissions are elongated on similar scales and position angles, there is no one-to-one correspondence between the radio and X-ray features in the source. The most likely origin for the extended X-ray emission in 1138-262 is thermal emission from shocked gas, although we cannot rule-out a contribution from inverse Compton emission. If the emission is from hot gas, the gas density is 0.05 cm^{-3} and the gas mass is 2.5x10^{12} M_solar. The pressure in this hot gas is adequate to confine the radio emitting plasma and the optical line emitting gas. We set an upper limit of 1.5x10^{44} erg/s to the 2 to 10 keV luminosity of any normal cluster atmosphere associated with 1138-262. No emission was detected from any of the Ly alpha emitting galaxies in the (proto-) cluster around 1138-262, outside of the Ly alpha halo of 1138-262 itself, to a 2 to 10keV luminosity limit of 1.2x10^{43}erg/s.

description: Chemotherapy is classified as a high-alert and hazardous drug by the National Institute for Occupational Safety and Health (OSHA). The American Society of Clinical Oncology (ASCO) and the Oncology Nursing Society (ONS) are the two organizations that recently revised the ONS Chemotherapy and Immunotherapy Certification Course curriculum in 2019 for oncology nurses. This revision included a shift from an in-person process, to one that is now fully online as a self-learning module. An increase in chemotherapy administration errors was noted this past year in newly certified oncology nurses at this DNP project site, who had completed this online certification process. Reports of low confidence and confidence levels were reported by these nurses, when administering these high-alert medications. The purpose of this DNP quality improvement study was to assess whether the use of chemotherapy administration simulation training would have any effect on confidence and competency levels in newly certified oncology nurses. Eleven nurses participated in two chemotherapy administration simulation experiences during November 2020. The entire group of participants improved their scores on a selfconfidence and competency tool upon completion of the two simulations and debriefing sessions, using pre- and post-testing measurements. The next steps are to observe whether the number of chemotherapy administration errors of these newly certified oncology nurses differs from that of the previous year.

description: We explore whether the rest-frame near-UV spectral region, observable in high-redshift galaxies via optical spectroscopy, contains sufficient information to allow the degeneracy between age and metallicity to be lifted. We do this by testing the ability of evolutionary synthesis models to reclaim the correct metallicity when fitted to the near-UV spectra of F stars of known (sub-solar and super-solar) metallicity. F stars are of particular interest because the rest-frame near-UV spectra of the oldest known elliptical galaxies at z > 1 appear to be dominated by F stars near to the main-sequence turnoff. We find that, in the case of the F stars, where the HST ultraviolet spectra have high signal:noise, model-fitting with metallicity allowed to vary as a free parameter is rather successful at deriving the correct metallicity. As a result, the estimated turnoff ages of these stars yielded by the model fitting are well constrained. Encouraged by this we have fitted these same variable- metallicity models to the deep, optical spectra of the z \simeq 1.5 mJy radio galaxies 53W091 and 53W069 obtained with the Keck telescope. While the age-metallicity degeneracy is not so easily lifted for these galaxies, we find that even when metallicity is allowed as a free parameter, the best estimates of their ages are still \geq 3 Gyr, with ages younger than 2 Gyr now strongly excluded. Furthermore, we find that a search of the entire parameter space of metallicity and star formation history using MOPED (Heavens et al., 2000) leads to the same conclusion. Our results therefore continue to argue strongly against an Einstein-de Sitter universe, and favour a lambda-dominated universe in which star formation in at least these particular elliptical galaxies was completed somewhere in the redshift range z = 3 - 5.

 Note: Since Bunge did not designate an herbarium location for his types and there are significant portions of his collections at both LE and P (Hb. Cosson), lectotypification of C. heratensis is necessary. Both collections at LE are small and without mature fruits, while one of the collections at P is in good shape, and includes good vegetative material, flowers, and fruits (P00741835!). For these reasons it is chosen as the lectotype. There are not digitized collections of this type from G, although it is expected that a duplicate resides there, as suggested by Hedge and Lammond (1970), and given the naming of the species by Boissier.

description: Recent developments of the covariant Bethe-Salpeter (BS) approach with the use of the separable interaction for the deuteron are reviewed. It is shown that the BS formalism allows a covariant description of various electromagnetic reactions like the lepton-deuteron scattering, deuteron electro-disintegration, deep inelastic scattering (DIS) of leptons on light nuclei. The procedure of the construction of the separable nucleon-nucleon (NN) interaction is discussed. The BS formalism facilitates analysis of the role of the P-waves (negative energy components) in the electromagnetic properties of the deuteron and its comparison with the nonrelativistic results. Furthermore the covariant BS approach makes it possible to analyze DIS of leptons from the deuteron in a model independent way and to extend the formalism to DIS reactions on the light nuclei.

description: In this paper we review the theory of the ``falling chimney'', which deals with the breaking in mid-air of tall structures, when they fall to the ground. We show that these ruptures can be caused by either shear forces, typically developing near the base, or by the bending of the structure, which is caused primarily by the internal bending moment. In the latter case the breaking is more likely to occur between one third and one half of the height of the chimney. Small scale toy models are used to reproduce the dynamics of the falling chimney. By examining photos taken during the fall of these models we test the adequacy of the outlined theory. This type of experiment, easy to perform and conceptually challenging, can become part of a rotational mechanics lab for undergraduate students.

description: Justicia spicigera Schltdl. (Acanthaceae) is used for treatment of gastrointestinal illnesses therapy in traditional medicine. The objective of this study was to give evidence of the antinociceptive and spasmolytic effects of the J. spicigera ethanol extract (JS EtOH) using in in vivo and/or in vitro assays. The JS EtOH exerted regulatory effect on the motility and a partial relaxing response on the intestinal tissue. Furthermore, a significant abdominal antinociceptive response was obtained in mice, which was totally abolished in the presence of 5-HT1A receptor antagonist (WAY100635, 0.1 mg/kg, s.c.) and partially by blocking opioid receptors (NX, 1 mg/kg, i.p.), whereas the inhibition of the NO synthesis (L-NAME, 30 mg/kg, i.p.) facilitated antinociception of this extract. Kaempferitrin was isolated and identified as major secondary metabolite. These results support the analgesic and spasmolytic-like activity of J. spicigera aerial parts involving inhibitory neurotransmission reinforcing the potential of this medicinal plant for alleviating pain.

title: Development of the Diffusive Gradients in Thin Films Technique for the Measurement of Inorganic Arsenic Speciation in Water and the Investigation of Arsenic Sediment Biogeochemistry

description: A novel diffusive gradients in thin films (DGT) technique for the measurement of inorganic arsenic speciation in situ was developed and evaluated. In addition, a diffusive equilibration in thin films (DET) technique was optimized for the high-resolution, colorimetric measurement of iron(II) in sediment porewaters. These techniques were then utilized to investigate processes of arsenic mobilization in sediments and the effect of changing redox conditions on the cycling of arsenic in freshwater and marine sediments. A titanium dioxide-based adsorbent, Metsorb™, was evaluated as a DGT adsorbent for measuring total inorganic arsenic (AsIII and AsV), as well as selenite (SeIV). Performance characteristics such as diffusion coefficients, linear accumulation over time, the effect of pH and ionic strength, and the capacity of the adsorbent were tested and found to be acceptable. The method was also evaluated in the field and found to accurately and precisely measure environmentally relevant arsenic concentrations. The speciation of inorganic arsenic was achieved by developing a second DGT technique that selectively measured AsIII in the presence of AsV. This new technique utilized a mercaptopropylfunctionalized silica gel as a selective adsorbent for AsIII, allowing the speciation of total inorganic arsenic to be calculated by deploying both sampler types simultaneously and calculating the AsV concentration by difference. This new approach to in situ arsenic speciation was successfully evaluated at a variety of pH levels and ionic strengths, and in the challenging matrix of seawater. The newly developed DGT techniques for arsenic speciation were applied to the investigation of arsenic mobility in sediments. To aid in this, a recently described colorimetric DET technique was optimized for the measurement of iron(II) concentrations in sediment porewater. The diffusive gel located at the front of the DGT samplers was utilized as the DET gel for colorimetric analysis of iron(II), enabling co-distributions of these analytes to be measured in situ. The combined DET – DGT approach was applied to freshwater, estuarine and marine sediment mesocosms to investigate the relationship between the reductive dissolution of iron(III) (hydr)oxide minerals and the release of arsenic to sediment porewaters. The effect of induced anoxia and subsequent reoxygenation on arsenic and iron cycling within freshwater and marine sediments was also investigated using sediment mesocosm incubations and the newly developed DET and DGT techniques. These techniques, used in conjunction with sediment mesocosms, proved to be a powerful new approach for the investigation of arsenic biogeochemistry and the mechanisms of arsenic mobilization in the environment.

description: We report on a systematic search for X-ray emission from pre-main sequence and young main sequence stars in the Taurus-Auriga-Perseus region. Our stellar sample consists of all T Tauri stars from the Taurus-Auriga region, and all late-type stars from the Pleiades and Hyades clusters which have been observed by the ROSAT PSPC in pointed observations. We present the X-ray parameters for all observed stars in tables, and study the connection between coronal X-ray activity and stellar parameters for different subgroups of our sample. In particular we compile X-ray luminosity functions (XLF), and discuss the relations between X-ray emission and spectral type, age, and rotation, on the largest sample so far.

description: Planetary habitability is in part determined by the atmospheric evolution of a planet; one key component of such evolution is escape of heavy ions to space. Ion loss processes are sensitive to the plasma environment of the planet, dictated by the stellar wind and stellar radiation. These conditions are likely to vary from what we observe in our own solar system when considering a planet in the habitable zone around an M-dwarf. Here we use a hybrid global plasma model to perform a systematic study of the changing plasma environment and ion escape as a function of stellar input conditions, which are designed to mimic those of potentially habitable planets orbiting M-dwarfs. We begin with a nominal case of a solar wind experienced at Mars today, and incrementally modify the interplanetary magnetic field orientation and strength, dynamic pressure, and Extreme Ultraviolet input. We find that both ion loss morphology and overall rates vary significantly, and in cases where the stellar wind pressure was increased, the ion loss began to be diffusion or production limited with roughly half of all produced ions being lost. This limit implies that extreme care must be taken when extrapolating loss processes observed in the solar system to extreme environments.
