title: Experiment data for "Observation of critical phase transtition in a generalized AAH model with superconducting qubits"

description: We simulated the one-dimensional generalized Aubry-Andre-Harper model for extended, localized and critical phases by using a programmable quantum processor with 10 superconducting qubits interacted through tunable couplers. We studied the properties of phase transitions and many-body dynamics in the presence of quasi-periodic modulations for both off-diagonal hopping coefficients and on-site potentials of the model controlled respectively by adjusting strength of couplings and qubit frequencies. We observed the spin transport for initial single- and multi-excitation states in different phases, and characterize phase transitions by experimentally measuring dynamics of participation entropies.

title: Filter Cake Biochar as a Soil Conditioner Cultivated with Native Cerrado Species: Effect on Soil Chemical and Microbiological Properties

description: Abstract The objective of this study was to evaluate the effect of filter cake biochar on the chemical and microbiological attributes of a dystrophic red-yellow latosol cultivated with macaúba (Acrocomia aculeata), araçá (Psidium firmum) and cajuzinho do cerrado (Anacardium humile), species native to the Cerrado. Thus, the responses of soil attributes were evaluated 120 days after transplanting the seedlings using four doses of biochar (1%, 2%, 4% and 8% v/v) and two control treatments (one with soil correction and fertilization and the other with no fertilization). The attributes evaluated were pH, contents of calcium, magnesium, phosphorus, potassium, CTC, total and microbial organic carbon and nitrogen, and C:N ratio. For the soils cultivated with the three Cerrado species, the 1% dose of biochar and mineral fertilization were the treatments that best conditioned the soil during the cultivation period and promoted a better response of the chemical and microbiological attributes of the soil.

title: DETERMINATION OF PHOSPHATIDYLETANOL IN DRIED BLOOD SPOT BY UHPLC-MS/MS: EVALUATION OF ALCOHOL CONSUMPTION IN CHEMICAL DEPENDENTS

description: We developed and validated an UHPLC-MS/MS method for the quantification of phosphatidylethanol (PEth) in dried blood spots (DBS). Sample preparation was a liquid extraction and chromatographic separation was performed in an Acquity C8 column. The mobile phases were 4 mM ammonium acetate in water (A) and acetonitrile (B) at 24:76 (v/v). The total analytical run time was 6 minutes, with retention time of 3.36 min for PEth and 4.13 min for phosphatidylpropanol. The method was linear from 10 to 3000 ng mL-1, specific, with, precise and accurate. The analyte was stable in DBS stored from -20 to 45 °C for 21 days. Matrix effect was compensated with the internal standard (-5.21% to + 6.09%). The method was applied in the evaluation of alcohol consumption in DBS from 25 chemical dependents. The PEth concentrations ranged from 14.5 to 2380.8 ng mL-1, with significant correlation with the self-report alcohol consumption AUDIT scores (r=0.41).

title: Amazon chicory: growing at full sunlight or under shade?

description: ABSTRACT Climatic factors can decisively influence the growth and productivity of agricultural crops. For unconventional vegetables, such as the Amazon chicory, the influence of sunlight on growing cycle is unknown. The aim of this study was to evaluate the influence of shading levels on the productive performance of Amazon chicory. The authors used a randomized block design, with four treatments and five replicates. The treatments were black polypropylene screens, 30, 50 and 70% shading, and cultivation at full sunlight. Vegetative development and production traits were evaluated. Correlation and principal components analysis (PCA) were performed with the aid of the computer program R. No significant difference between the shading levels for the evaluated traits was noticed. Nevertheless, the cultivation at full sunlight allowed an increase in production, compared to the 70% shading screen. A strong positive correlation between productivity, leaf fresh mass and amount of water in the shoot area was verified, with a coefficient equal to 1. Only the leaf area characteristic was poorly correlated with other traits (angle &gt;90º). Therefore, we suggest growing the Amazon chicory both at full sunlight and under 70% shading.

title: Dynamics of ammonia volatilization from NBPT-treated urea in tropical acid soils

description: ABSTRACT The urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT) reduces NH3 losses from urea (UR) surface-applied to soils, but its efficacy may be lower in acidic soils. The period when urease inhibition occurs efficaciously may change with soil pH. This needs to be clarified in tropical soils which are commonly acidic. This study evaluated the effectiveness of NBPT-treated urea to delay and reduce ammonia volatilization in two soils at three pH levels. Two experiments were conducted under laboratory conditions in soils with different textures (sandy-clay and clay). The treatments consisted of three soil pH levels and two N sources (UR and UR + NBPT), with five replicates. The soil pH values were adjusted and reached values of 4.5, 5.6, and 6.4 in the sandy-clay, and 4.5, 5.4, and 6.1 in the clay soil. Ammonia volatilization was measured using glass chambers (1.5 L). In the sandy-clay soil, NH3 losses were 40-47 % of the UR-N. In the clay soil, losses were 26-32 %. The addition of NBPT to UR reduced the NH3 volatilization by 18-53 %; the inhibitor decreased the N losses under all soil pH conditions but was significantly less efficient in acidic soils (pH 4.5). The lower efficiency of the inhibitor under acidic conditions was more evident in the first few days: 50 % of the total NH3 losses occurred in less than four days in soils with pH 4.5, but in 8-11 days in soils with pH above 5.4. The rapid loss in efficiency in more acidic soils is a drawback. Using NBPT in severely acidic soils showed a relatively small advantage over untreated UR as the inhibitor did not provide extra time for fertilizer incorporation and further reduction of NH3 losses.

title: Management control mechanisms, environmental unpredictability and organizational resilience

description: Abstract This article analyzes the (formal and informal) role of control mechanisms in fostering (proactive and reactive) organizational resilience of financial technology startups (fintechs), considering the moderating effect of environmental unpredictability. First, there is little evidence on formal and informal control mechanisms in the context of organizational resilience. Second, studies on management controls focus on some resilience approaches, however, they do not address resilience from a proactive and reactive perspective. Third, the literature on the effects of environmental unpredictability on contemporary organizations, like the fintechs, is still scarce. On the one hand, new evidence is added to the literature on management control and organizational resilience, the understanding of antecedents of resilience in startups is expanded, and insights are provided on the effects of environmental unpredictability on the alignment of management controls and objects of control. On the other hand, insights are provided on control mechanisms that fintechs can benefit from to building organizational resilience, both to anticipate and prepare and to act and formulate responses in the face of business disruptions and uncertain times. The findings benefit the building and strengthening of resilience in fintechs, which becomes key for these startups to survive and consolidate themselves in the financial market. Data have been collected by survey and analyzed through structural equation modeling. Additional investigation has been conducted via fuzzy-set qualitative comparative analysis. The main results reveal that: (i) formal and informal control mechanisms foster proactive and reactive organizational resilience; (ii) in scenarios of high environmental unpredictability, greater attention given to informal controls results in higher proactive resilience levels; and (iii) there are four (five) organizational configurations that lead fintechs to high proactive (reactive) resilience.

title: Acceptability and applicability of an intervention programme with substance addicts

description: Abstract The complexity of the problems related to the harmful use of substances requires regular questioning of practices. This article aims to explore the acceptability and applicability of an intervention programme for patients with problematic substance use. Qualitative study. Data collection, through a focus group with 6 nurses and 6 semi-structured interviews with patients under treatment. We have used lexicographic textual analysis. From the focus group, 151 text segments were analysed, retaining 85.8% of the total for the creation of five classes. An analysis of similarity led to the formation of two central nuclei, represented by the words “Nursing” and “Intervention”. From interviews, 252 text segments were analysed, retaining 71.83% for the creation of 5 classes. An analysis of similarity led to the formation of three central nuclei, represented by the words “want”, “programme” and “see”. Nurses recognise the need for a more structured and flexible approach focused on people’s needs. Users also affirm the need for flexible interventions, without a pre-established time frame, that promote labour integration, therapeutic support for abstinence and management of comorbidities.

title: Irrigation management of common bean cultivars with contrasting growth habits

description: ABSTRACT A study was undertaken comparing the water requirements of two common bean ( Phaseolus vulgaris L.) cultivars to generate specific recommendations aimed at optimizing water use. To accomplish this work, the agronomic performance, responsiveness to water and water productivity of these two common bean cultivars of determinate and indeterminate growth habits were identified. The 2-year experiment was carried out during the winter growing season in the southeast of Brazil. Cultivars IAC Imperador, with an early season of determinate growth habit, and IPR Campos Gerais, having a mid-season of indeterminate growth habit, were subjected to five irrigation levels (54, 70, 77, 100, and 132 % of the crop evapotranspiration). Water deficit affected agronomic performance, reducing plant height (by up to 29 %), leaf area index (by up to 40 %), soil cover fraction (by up to 28 %), and grain yield (GY - by up to 31 %), in both cultivars. In contrast, excess water was more detrimental to cultivar IAC Imperador. Cultivar IPR Campos Gerais produced 18 % more than GY, showing superior water productivity and response to irrigation depth than IAC Imperador. Out of all the variables evaluated, the soil cover fraction correlated the most with grain yield in both common bean cultivars during the 2-year study. In other words, cover fraction evaluation in common bean allows for estimating crop production potential, which helps producers and technicians in their decision making regarding management practices. Thus, a cultivar directly affects water use in common bean production, thereby suggesting the need for a or water conservation strategy and sustainability of irrigated common bean production.
