Pressure-Induced Polaronic to Itinerant Electronic Transition in La 1 − x Sr x MnO 3 Crystals

Measurements of the temperature dependence of the resistivity {rho}(T) and thermoelectric power {alpha}(T) under several hydrostatic pressures were made on single crystals of La{sub 1{minus}x}Sr {sub x}MnO{sub 3} with x=0.12 and 0.15 in which charge ordering takes place below T{sub co} . We report a transition from the polaronic to an itinerant electronic state in the pressure range 5{lt}P{lt}6 kbar in the x=0.15 sample. The polaronic state is modeled as a mobile three-manganese cluster within a matrix of dynamic Jahn-Teller deformations at Mn( III) ions. {copyright} {ital 1997} {ital The American Physical Society}
Flavodiiron Oxygen Reductase from Entamoeba histolytica MODULATION OF SUBSTRATE PREFERENCE BY TYROSINE 271 AND LYSINE 53 *

Background: Flavodiiron proteins (FDPs) are O 2 and/or NO reductases. Results: Point mutations, near the active site of an Entamoeba histolytica O 2 -selective FDP, result in increased NO reductase activity and faster inactivation in the reaction with O 2 . Conclusion: Residues close to the FDPs diiron site modulate the preference toward O 2 or NO. Significance: We unravel molecular determinants of substrate specificity in enzymes affording resistance to oxygen and/or nitric oxide.
REVIEW Experiments using microarray technology: limitations and standard operating procedures

Microarrays are a powerful method for the global analysis of gene or protein content and expression, opening up new horizons in molecular and physiological systems. This review focuses on the critical aspects of acquiring mean-ingful data for analysis following ﬂuorescence-based target hybridisation to arrays. Although microarray technology is adaptable to the analysis of a range of biomolecules (DNA, RNA, protein, carbohydrates and lipids), the scheme presented here is applicable primarily to customised DNA arrays fabricated using long oligomer or cDNA probes. Rather than provide a comprehensive review of microarray technology and analysis techniques, both of which are large and complex areas, the aim of this paper is to provide a restricted overview, highlighting salient features to provide initial guidance in terms of pitfalls in planning and executing array projects. We outline standard operating procedures, which help streamline the analysis of microarray data resulting from a diversity of array formats and biological systems. We hope that this overview will provide practical initial guidance for those embarking on microarray studies. Nevertheless, it is also apparent that the increase in scan PMT has a strictly linear effect on the signal intensities. If we then examine the next two graphs (B and C) in this series, we can clearly see how the range of signal intensities increases to cover more of the available spectrum, lifting low to medium strength signals out of the possible background noise. The last graph (D) is not linear in the high signal range, meaning the highest scan setting in this series causes signal saturation in a number of spots. Based on this, we would here decide to carry forward data from scan setting 4 ( y -axis in C and x -axis in D), the highest possible scan with the best representation of the data on this chip.
Trajectory of Time-based Visual Selection for Moving Objects

By approximately 6 years of age, children can use time-based visual selection to ignore stationary stimuli, already in the visual field and prioritize the selection of newly arriving stimuli. This ability can be studied using preview search, a version of the visual search paradigm with an added temporal component, in which one set of distractors is presented (previewed) before a second set that contains the target item. Preview search is more efficient than if all items are presented simultaneously, suggesting that temporally ‘old’ objects can be ignored (the preview benefit). In two experiments, we examined the developmental trajectory for ignoring old moving distractors in a sample of 192 6, 8, and 12-year-old children (49% female, predominantly white), with adults as controls (75% female, predominantly white), in the UK. The results showed an absence of the ability to ignore old moving distractors in 6-year-olds and confirmed its presence from 8 years of age. However, full development of this ability, which includes maintaining inhibition of old items over extended periods, was only present from the age of 12. Individual differences in EFs, namely inhibition, were associated with preview search efficiency in 6-year-olds and adults. Overall, the results suggest a developmental trajectory in the ability to ignore moving old objects that occurs in two stages and develops later than the ability to ignore stationary objects. The results are discussed in terms of underlying inhibitory mechanisms, in addition to individual differences in the expression of this ability.
Better Together: Jointly Optimizing ML Collective Scheduling and Execution Planning using SYNDICATE

: Emerging ML training deployments are trending towards larger models, and hybrid-parallel training that is not just dominated by compute-intensive all-reduce for gra-dient aggregation but also bandwidth-intensive collectives (e.g., all-to-all). These emerging collectives exacerbate the communication bottlenecks despite heterogeneous network interconnects with ample multipath opportunities. In this work, we propose S YNDICATE , a systematic, general framework to minimize communication bottlenecks and speed up training for both state-of-the-art and future large-scale models and interconnects. S YNDICATE proposes a novel abstraction, the motif, to break large communication work as smaller pieces as part of execution planning. S YNDICATE also does joint optimization of scheduling and execution planning by rethinking the interfaces in the networking systems stacks used for ML training. Motifs afford greater flexibility during scheduling and the joint optimizer exploits this flexibility by packing and ordering communication work so as to maximize both network utilization and overlap with compute. This improves the speed of training state-of-the-art large models by 21-74%.
Towards Normalization of Simplicial Type Theory via Synthetic Tait Computability

Riehl and Shulman [12] introduced a simplicial extension of (homotopy) type theory to reason synthetically about (∞, 1)-categories. Indeed, the semantics of this theory matches up with established results from homotopy theory, i.e., the synthetic (∞, 1)-categories in the theory correspond externally to internal (∞, 1)-categories in an arbitrary given∞-topos (implemented as complete Segal objects), cf. [10, 14, 23]. However, certain meta-theoretic properties of this simplicial type theory (STT), such as canonicity and normalization, have not been investigated yet. In this talk, we explain our progress towards establishing a normalization result for STT (without any axioms such as function extensionality) using the framework of synthetic Tait computability (STC). The latter is due to Sterling and Harper [17] and has been used by Sterling–Angiuli [16] and Sterling [15] to establish meta-theoretical results for cubical type theory (CTT) such as canonicity (cf. [13]) and normalization, moreover in a syntax-invariant manner.
QUALITY OF WORK LIFE AND CORPORATE SOCIAL RESPONSIBILITY: A MULTIPLE CASE STUDY.

The main objective of this article was to know the perception of employees regarding their quality of life at work, to assess the satisfaction in the activity of employees of companies, which have social responsibility actions, regarding the main factors that interfere in their quality of life. Exploratory qualitative research was carried out, through multiple case studies, with 5 companies listed among the 150 best to work for, and which publish balance sheets in the Global Report Initiative (GRI). The study allowed us to conclude that the vast majority of life´s quality indicators at work were satisfactorily evaluated in the 5 analyzed, which can be considered representative in Brazil in terms of Corporate Social Responsibility practices.

The Association between Index of Nutritional Quality (INQ) and Obesity: Baseline Data of Kharameh Cohort

Obesity is an increasing problem that can lead to noncommunicable diseases. The role of dietary factors on one's obesity is confirmed in many studies. One nutritional approach that can be used for assessment of the foods and diets is the Index of Nutritional Quality (INQ). Our study is aimed at exploring the association between INQ and obesity. Our hypothesis is that enriched and high-quality diets reduce the risk of overweight or obesity. This study was carried out on 6248 overweight and obese participants, from whom 4356 (69.7%) and 1892 (30.3%) were overweight and obese, respectively. To assess the dietary intake for the participants, a valid food frequency questionnaire (FFQ) with 130 food items was utilized. The analysis revealed an inverse association between the overweight and the INQ of iron, thiamin, riboflavin, B6, folate, zinc, magnesium, calcium, and vitamin C and E. For the obese group, this inverse association was found for iron, B6, folate, zinc, magnesium, calcium, and vitamin C and E. These results approved our hypothesis that a rich nutrition diet may lead to a lower risk of obesity.
Trimers of MnO6 octahedra and ferrimagnetism of Ba4NbMn3O12

Ba4NbMn3O12 is reported, synthesized by a solid state method in air. The crystal structure, determined by performing refinements on room temperature powder x-ray diffraction data by the Rietveld method, consists of Mn3O12 trimers in the configuration of three face-sharing MnO6 octahedra, with the trimers arranged in triangular planes. An effective moment of 4.82 μB/f.u is observed and competing antiferromagnetic and ferromagnetic interactions between Mn ions are inferred from the Weiss temperature of −4 K and the ferrimagnetic ordering transition of approximately 42 K. Ba4NbMn3O12 is a semiconductor with a transport activation energy of 0.37 eV.
Hyperentanglement-assisted Bell-state analysis

We propose a simple scheme for complete Bell-state measurement of photons using hyperentangled states-entangled in multiple degrees of freedom. In addition to hyperentanglement, our scheme requires only linear optics and single photon detectors, and is realizable with current technology. At the cost of additional classical communication, our Bell-state measurement can be implemented nonlocally. We discuss the possible application of these results to quantum dense coding and quantum teleportation.
Journal Pre-proof Mediterranean G6PD variant mitigates expression of DNA methyltransferases and right heart pressure in experimental model of pulmonary hypertension

DNA methylation potentially contributes to the pathogenesis of pulmonary hypertension (PH). However, the role of DNA methyltransferases (DNMTs: 1, 3a, and 3b), the epigenetic writers, in modulating DNA methylation observed in PH remains elusive. Our objective was to determine DNMT activity and expression in the lungs of an experimental rat models of PH. Because the activity of DNMTs is metabolically driven, another objective was to determine the role of glucose-6-phosphate dehydrogenase (G6PD) in regulating DNMT expression and activity in the lungs of novel loss-of-function Mediterranean G6PD variant (G6PD S188F ) rats. As outlined for modeling PH, rats injected with sugen5416 (SU) were placed in a hypoxia (Hx) chamber set at 10% oxygen for 3 weeks and then returned to normoxia (Nx) for 5 weeks (SU/Hx/Nx). Rats kept in atmospheric oxygen and treated with SU were used as controls. We assessed the activity and expression of DNMTs in the lungs of rats exposed to SU/Hx/Nx. Wild-type rats exposed to SU/Hx/Nx developed hypertension and exhibited increased DNMT activity and Dnmt1 and Dnmt3b expression. In G6PD S188F rats, which developed less of a SU/Hx/Nx-induced increase in right ventricle pressure and hypertrophy than wild-type rats, we observed a diminished increase in expression and activity of DNMTs, DNA hypomethylation, increased histone acetylation and methylation, and increased expression of genes encoding NOS3 and SOD2 – vascular-protective proteins. Collectively, increased DNMTs contribute to reduced expression of protective genes and to the pathogenesis of SU/Hx/Nx-induced experimental PH. Notably, G6PD regulates the expression of DNMTs and protective proteins in the lungs of hypertensive rats. We Our findings suggest that increased DNMT-catalyzed DNA methylation potentially contributes to the development and progression of PH pathology. What is more, they further suggest that G6PD contributes to the increase in DNMT expression and activity as well as modify expression of linker histone1H1 and increase histone acetylation/methylation resulting in the higher expression of genes encoding endothelial nitric oxide synthase 3 (NOS3), mitochondrial superoxide dismutase 2 (SOD2), and other vascular biology-related proteins in the lungs of rats with SU/Hx/Nx-induced experimental PH.
Zero mass limit of Kerr spacetime is a wormhole

We show that, contrary to what is usually claimed in the literature, the zero mass limit of Kerr spacetime is not flat Minkowski space but a spacetime whose geometry is only locally flat. This limiting spacetime, as the Kerr spacetime itself, contains two asymptotic regions and hence cannot be topologically trivial. It also contains a curvature singularity, because the power-law singularity of the Weyl tensor vanishes in the limit but there remains a distributional contribution of the Ricci tensor. This spacetime can be interpreted as a wormhole sourced by a negative tension ring. We also extend the discussion to similarly interpret the zero mass limit of the Kerr–(anti–)de Sitter spacetime.
Finding Competent Reviewers for Online Courses

: Identifying competent reviewers who can contribute helpful reviews for online courses is an imperative task for online learning platforms and course instructors. Online learners value reviews of recent course experience, as such a proactive approach to soliciting and incentivizing reviews from competent reviewers is needed. This research proposes two performance-based reviewer competence indicators, i.e., reviewers’ prior helpfulness and specialization, and tests their predictive power on reviewers’ contributing helpful online course reviews. A sample of 36,825 reviews and their reviewers on a leading MOOC platform in China was analyzed. Results show that both reviewers’ prior helpfulness and specialization predict the helpfulness of their review contribution. The predictive power of reviewers’ prior helpfulness is susceptible to situational conditions, including learners/reviewers’ working status and course learning performance, whereas that of reviewer specialization is relatively consistent. This research enhances the understanding of performance-based reviewer competence assessment, particularly in the online learning context. Its results can be directly applied to identify potential reviewers and solicit helpful online course reviews.
Higher order contributions to the effective action of Script N = 4 super Yang-Mills

The one-loop low-energy effective action for non-abelian = 4 supersymmetric Yang-Mills theory is computed to order F6 by use of heat kernel techniques in = 1 superspace. At the component level, the F5 terms are found to be consistent with the form of the non-abelian Born-Infeld action computed to this order by superstring methods. The F6 terms will be of importance for comparison with superstring calculations.
Thermo-field emission and the Nottingham effect

The thermo-field emission current and Nottingham effect are calculated for a wide range of temperatures (<or=6000 K), field strengths (<or=1010 V m-1) and work function (2-5 eV) of the emitter. The ranges of validity of known approximations are given and it is shown that the simple approximation formulae commonly used may give incorrect results to several orders of magnitude. New easy-to-use fit formulae for the emission current, the Nottingham heat and some important functions in the theory of electron emission are proposed. The main application of these approximations lies in the field of numerical modelling of the development of arc cathode spots.
The Spitzer Infrared Spectrometer view of V4334 Sgr (Sakurai's Object)

We present an observation of the very late thermal pulse object V4334 Sgr (Sakurai’s Object) with the Infrared Spectrometer (IRS) on the Spitzer Space Telescope. The emission from 5‐ 38 μm is dominated by the still-cooling dust shell. A number of features are seen in absorption against the dust shell, which we attribute to HCN and polyyne molecules. We use these features to determine the 12 C/ 13 C ratio for the absorbing gas to be ∼3.2 +3.2; this implies that, despite the H-content of the molecules, the hydrocarbon-bearing gas must have originated in material produced in the very late thermal pulse. We see no evidence of emission lines, despite the recently-reported optical and radio observations that suggest the effective temperature of the stellar remnant is rising.

Pale Orange Dots: The Impact of Organic Haze on the Habitability and Detectability of Earthlike Exoplanets

Hazes are common in known planetary atmospheres, and geochemical evidence suggests that early Earth occasionally supported an organic haze with significant environmental and spectral consequences. The UV spectrum of the parent star drives organic haze formation through methane photochemistry. We use a 1D photochemical-climate model to examine production of fractal organic haze on Archean Earth-analogs in the habitable zones of several stellar types: the modern and early Sun, AD Leo (M3.5V), GJ 876 (M4V), ϵ Eridani (K2V), and σ Boötis (F2V). For Archean-like atmospheres, planets orbiting stars with the highest UV fluxes do not form haze because of the formation of photochemical oxygen radicals that destroy haze precursors. Organic hazes impact planetary habitability via UV shielding and surface cooling, but this cooling is minimized around M dwarfs, whose energy is emitted at wavelengths where organic hazes are relatively transparent. We generate spectra to test the detectability of haze. For 10 transits of a planet orbiting GJ 876 observed by the James Webb Space Telescope, haze makes gaseous absorption features at wavelengths < 2.5 μm 2–10σ shallower than a haze-free planet, and methane and carbon dioxide are detectable at >5σ. A haze absorption feature can be detected at 5σ near 6.3 μm, but a higher signal-to-noise ratio is needed to distinguish haze from adjacent absorbers. For direct imaging of a planet at 10 pc using a coronagraphic 10 m class ultraviolet–visible–near-infrared telescope, a UV–blue haze absorption feature would be strongly detectable at >12σ in 200 hr.
CB 17: Inferring the Dynamical History of a Prestellar Core with Chemodynamical Models

We present a detailed theoretical study of the isolated Bok globule CB 17 (L1389) based on spectral maps of CS, HCO+, C18O, C34S, and H13CO+ lines. The intensity of the external UV field, the probability for molecules to stick onto dust grains, the core age, the infall, and rotation velocity all significantly affect the molecular line spectra. We demonstrate that these parameters are well constrained when results of the modeling are compared to observations in multiple lines of sight through the core. We use a detailed chemical model to compute the time-dependent abundances in a number of locations within the core. Both static and dynamically evolving cloud configurations are considered. These abundances are then used to simulate the spectral maps. We developed a general criterion that allows us to quantify the difference between observed and simulated spectral maps. By minimizing this difference, we isolate the model that represents a good approximation to the core chemical and kinematic structure. The chemical age of the core is about 2 Myr, while the most probable effective sticking probability value is 0.3-0.5. The spatial distribution of intensities and self-absorption features of optically thick lines is indicative of attenuated UV radiation of the core. The line asymmetry pattern in CB 17 is reproduced by a combination of infall, rotation, and turbulent motions with velocities of ~0.05, ~0.1, and ~0.1 km s-1, respectively. These parameters correspond to energy ratios Erot/Egrav ≈ 0.03, Etherm/Egrav ≈ 0.8, and Eturb/Egrav ≈ 0.05 (the rotation parameters are determined for i = 90°). Based on the angular momentum value, we argue that the core is going to fragment, i.e., to form a binary (multiple) system.
Toward an integrated framework for data exchange in microsystem applications

Miniaturized, integrated sensors and actuators called microsystems are a rapidly growing field with great future potential. In order to promote their use further, specialists must make them more accessible to system designers at all stages of development. This can be done through behavioral modeling of sensors and actuators which can be used in conjunction with models of the associated electronics to simulate a complete microsystem. Additionally, models of microsystem components realized during modeling and simulation can be retrieved for use in the assembly phase of manufacture. Here virtual-reality environments are used to aid in the realization and use of automated robot systems working with miniature components in the micron scale. The use of computer aided design and simulation tools in this field is critical owing to the high prototyping costs. Data exchange between the various systems is advantageous and reduces design and manufacturing costs while speeding up time to market.
