Oil recovery is strongly related to the wettability of reservoir rocks that are formed of quartz grains attached by mineral hydroxides and clay minerals. Illites and kaolinites are the most active due to their high specific surface areas and electrical charge densities. Therefore, these minerals’ relative affinities for oil or water when in contact with a water-oil mix are of great importance. In order to model such a complex system, we used a mix of organic model molecules of the oil constituents and water vapor. Their interactions were estimated by inverse gas chromatography (IGC). IGC experiments were performed using a carrier gas with controlled humidity. By means of IGC at infinite dilution conditions, the dispersive component of the surface energy, γsd, was determined. A strong decrease of γsd, due to water molecules shielding the highest-energy sites, was observed. The energetic surface heterogeneity of the clays was examined using IGC at finite concentration conditions, allowing the determination of organic probe adsorption isotherms in the presence of water. From these isotherms, adsorption energy distribution functions were computed for propanol-2 and pyridine probes. Water mainly modifies the illite distribution functions, whereas practically no change was observed in the case of kaolinite. This observation is related to the higher hydrophilicity of illite as compared with kaolinite, and explains the different behaviors of the 2 clay families in oil reservoirs.

Seed predation by rodents can strongly influence plant recruitment and establishment. The extent to which predation risk indirectly alters plant survival in tropical forests via impacts on granivory is unclear, making it difficult to assess the cascading impacts of widespread predator loss on tree recruitment and species composition. Experimental field studies that manipulate predation risk can help address these knowledge gaps and reveal whether antipredator responses among small mammals influence plant survival. We used camera traps and seed predation experiments to test the effects of perceived predation risk (via predator urine gel) on foraging behaviour of and seed removal by murid rodents in an unlogged and unhunted rainforest in Malaysian Borneo. We also explored the influence of seed traits (e.g., seed size) on removal by granivores and assessed whether granivore preferences for particular species were affected by predator urine. Murid visits to seed plots were positively related to overall seed removal, but were not affected by predator scent. Granivory was the lowest for the largest-seeded (>6 g) plant in our study, but was not influenced by predation risk. Predator urine significantly affected removal of one seed taxon (Dimoocarpus, ∼0.8 g), suggesting that removal by granivores may be affected by predation risk for some seed species but not others. This could have implications for plant species composition but may not affect the overall level of granivory.

Although the Cascajal Block (CB), an incised greenstone slab from southeastern Veracruz, Mexico, arguably contains the earliest written text in the New World, debate remains regarding the object's authenticity, dating, and cultural affiliation. To address these issues, this article details recent analyses of the CB via polynomial texture mapping (PTM), X-ray fluorescence (XRF), and scanning electron microscopy (SEM). PTM revealed new details that have resulted in a new epigraphic drawing of the block's incised text and allowed for improved identification of several constituent signs. Spectrometric analysis confirmed that the chemical composition of the CB matrix is consistent with serpentine and identified a uniform patina on its surface, which provided additional contextual data. SEM micrographs of polymer replica molds taken from the incised text evidence manufacturing traces that correspond to lapidary techniques observed on other Formative-period Olmec objects of secure provenience. Results assist in clarifying the archaeological contexts of the object and confirm that in terms of symbols, material, and manufacture the CB conforms to other Formative-period Olmec objects, supporting the object's authenticity, dating, and cultural affiliation.

Amorphous TiO2 and SnO2 electron transport layers (ETLs) were deposited by low-temperature atomic layer deposition (ALD). Surface morphology and x-ray photoelectron spectroscopy (XPS) indicate uniform and pinhole free coverage of these ALD hole blocking layers. Both mesoporous and planar perovskite solar cells were fabricated based on these thin films with aperture areas of 1.04 cm2 for TiO2 and 0.09 cm2 and 0.70 cm2 for SnO2. The resulting cell performance of 18.3 % power conversion efficiency (PCE) using planar SnO2 on 0.09 cm2 and 15.3 % PCE using mesoporous TiO2 on 1.04 cm2 active areas are discussed in conjunction with the significance of growth parameters and ETL composition.

Extensive areas of tropical forests have been, and continue to be, disturbed as a result of selective timber extraction. Although such anthropogenic disturbance typically results in the loss of biodiversity, many species persist, and their conservation in production landscapes could be enhanced by a greater understanding of how biodiversity responds to forest management practices. We conducted intensive camera-trap surveys of eight protected forest areas in Sabah, Malaysian Borneo, and developed estimates of Sunda clouded leopard Neofelis diardi population density from spatially explicit capture–recapture analyses of detection data to investigate how the species’ abundance varies across the landscape and in response to anthropogenic disturbance. Estimates of population density from six forest areas were 1.39–3.10 individuals per 100 km2. Our study provides the first evidence that the population density of the Sunda clouded leopard is negatively affected by hunting pressure and forest fragmentation, and that among selectively logged forests, time since logging is positively associated with abundance. We argue that these negative anthropogenic impacts could be mitigated with improved logging practices, such as reducing the access of poachers by effective gating and destruction of road access points, and by the deployment of anti-poaching patrols. By calculating a weighted mean population density estimate from estimates developed here and from the literature, and by extrapolating this value to an estimate of current available habitat, we estimate there are 754 (95% posterior interval 325–1,337) Sunda clouded leopards in Sabah.

Objective
Aripiprazole lauroxil (AL) is a long-acting injectable atypical antipsychotic that was evaluated for the treatment of schizophrenia in a randomized, placebo-controlled, Phase 3 study. Here, we present exploratory analyses of supportive efficacy endpoints.
MethodsPatients experiencing an acute exacerbation of schizophrenia received AL 441 mg intramuscularly (IM), AL 882 mg IM, or matching placebo IM monthly. Supportive endpoints included changes from baseline at subsequent time points in Clinical Global Impression-Severity (CGI-S) scale score; Positive and Negative Syndrome Scale (PANSS) Total score; PANSS Positive, Negative, and General Psychopathology subscale scores; PANSS Marder factors (post hoc); and PANSS responder rate. Overall response rate, based on PANSS Total score and Clinical Global Impression–Improvement (CGI-I) scale score, was also analyzed.
ResultsOf 622 patients who were randomized, 596 had ≥1 post-baseline PANSS score. Patients were markedly ill at baseline (mean PANSS Total scores 92–94). Compared with placebo, CGI-S scores; PANSS Positive, Negative, and General Psychopathology subscale scores; and PANSS Marder factors were all significantly (p<0.001) improved by Day 85 with both AL doses, with significantly lower scores starting from Day 8 in most instances. Treatment response rates were significantly (p<0.001) greater with both doses of AL vs placebo.
ConclusionAL demonstrated robust efficacy on CGI-S score, PANSS subscale scores, PANSS Marder factors, and response rates. Study limitations included use of a fixed dose for initial oral aripiprazole and fixed monthly AL doses without the option to individualize the oral initiation dosing or injection frequency for efficacy, tolerability, or safety.

Many econometric models can be analyzed as finite mixtures. We focus on two-component mixtures, and we show that they are nonparametrically point identified by a combination of an exclusion restriction and tail restrictions. Our identification analysis suggests simple closed-form estimators of the component distributions and mixing proportions, as well as a specification test. We derive their asymptotic properties using results on tail empirical processes and we present a simulation study that documents their finite-sample performance.

Estimation of the quality of commercial diets is a topic of interest for the majority of dog owners. Recently, in a French consumer association magazine, an evaluation of eight dog commercial dry diets (from super-premium, basic-nutrition, private-label and economy brands) according to several nutritional criteria was published. The aims of the study were: (1) to evaluate the apparent digestibility of these diets; (2) to score these diets according to digestibility results; and (3) to compare these data with the scoring of the magazine. Six adult Beagle dogs were enrolled for the digestibility trials. Diets were scored according to energy, crude protein and crude fat (CF) apparent digestibility coefficients, digestible protein-to-energy ratios and ash content. Each of the five criteria was scored from 4 to 20 points. The ranges of crude protein, CF, crude fibre and ash content were 20·9–30·6 %, 6·8–19·7 %, 2·2–3·3 % and 4·6–9·7 % on a DM basis, respectively. The ranges of energy, crude protein and CF apparent digestibility coefficients were 72·6–87·7 %, 70·4–82·5 % and 76·1–95·4 %, respectively. The range of the protein-to-energy ratio was 10–14 digestible crude protein per MJ metabolisable energy. Little overlap in the scoring systems was found, but the private-label brand and economy brand diets presented the lowest scores in the two systems. These results showed that the evaluation of commercial diets should take into account multiple nutritional aspects. In particular, analytical and biological (digestibility) criteria should be considered as complementary in the evaluation of dry dog commercial diets.

We compared the characteristics of neural cells derived from induced pluripotent stem (iPS) cells from a patient with multiple sclerosis versus neurally differentiated control iPS cells of a healthy individual. The iPS cells were differentiated toward the oligodendrocyte lineage using a four-step protocol established for the differentiation of embryonic stem cells. The resulting cell population was immunostained on day 112 of differentiation for the presence of oligodendrocytes and analyzed by transmission electron microscopy (TEM). Both patient and control samples resembled a mixed population of neural cells rather than oligodendroglia of high purity, including neural stem cell-like cells and possibly oligodendrocytes demonstrable by TEM.

Understanding the habitat preferences of native and non-native species may offer valuable insights into the mechanisms favouring invasion of disturbed habitats. This study investigated the determinants of trap-site detection probability of three native (Maxomys surifer, Maxomys whiteheadi and Leopoldamys sabanus) and one invasive (Rattus rattus) species of terrestrial murid (Muridae) in logged and unlogged forests of northern Borneo. We established four and two trapping grids in repeatedly logged and unlogged forest, respectively, for a total of 500 sampled trap sites. From these, we obtained 504 detections of the four species over 3420 trap nights. For each species, probability of detection was modelled as a function of both the structural components and disturbance level of the forest patch measured around each trap site. Each of the four species showed contrasting microhabitat preferences: M. surifer favoured increased canopy closure and intermediate ground and understorey vegetation cover; M. whiteheadi preferred increased ground vegetation cover and canopy height; L. sabanus favoured sites with larger amounts of coarse woody debris and less leaf litter; and R. rattus was associated with increased ground vegetation cover. Within logged forest, detection probabilities of the three native species did not vary significantly with level of patch disturbance, whereas that of the invasive R. rattus increased markedly in more degraded sites. This latter finding will have increasingly important implications when considering the rapid degradation of forests in the region, and the resulting expansion of suitable habitat for this competitive species.

During a recent underwater archaeological survey of the Arroyo Pesquero, members of the Proyecto Arqueológico Arroyo Pesquero discovered an extraordinary and unusual archaeological specimen made of mottled brown and white jadeite. This artifact, most likely dating to the Middle Formative period (900–400 b.c.), is significant for two reasons. Firstly, because this object is the first find discovered at the site during a systematic archaeological investigation and thus has archaeological provenience and, secondly, because of the iconographic elements it possesses and its one-of-a-kind form. This article begins with a short background on the Arroyo Pesquero site, including its discovery, history of looting, and archaeological investigations. We then briefly describe the present investigation and the discovery of the artifact itself. This is followed by a description of the artifact—its form, iconography, and its possible functions. We conclude with some comments on the specimen within the framework of Middle Formative Olmec iconography.

The growth hormone (GH)–insulin-like growth factor-1 (IGF-1) axis is dramatically altered in patients with anorexia nervosa (AN). The aim of the present study was to investigate whether GH and IGF-1 could be predictors of outcome in patients with a restrictive form of AN. Blood levels of GH, IGF-1, adipocytokines, ghrelin, insulin, glucose, and sex and thyroid hormones were measured in eleven women inpatients with AN and in ten healthy women controls. Three stages were compared during refeeding: admission (T0), when BMI reached 16 kg/m2 (T1) and at discharge when BMI reached 17·5 kg/m2 (T2). Clinical status was assessed 6 months after discharge from hospital (T3), and remission was defined by the maintenance of a BMI ≥ 17·5 kg/m2. AN patients in remission (AN-R; n 6) had significantly higher GH levels at admission than those who relapsed (AN-NR; n 5) (P< 0·05). During refeeding (Δ = T2 − T0), the AN-R group differed from the AN-NR group only by both GH level decrease (P< 0·05) and BMI increase (P< 0·05). In multiple regression analysis, ΔGH was associated negatively and significantly and Δleptin and Δbody fat mass levels were associated positively and significantly with BMI at T3 and explained 88 % of its variability (r2 0·88, P< 0·05). The present study suggests that a low GH level at admission and the absence of its decrease after weight recovery could predict short-term relapse in women suffering from a restrictive form of AN.

Background.
Multidisciplinary antimicrobial utilization teams (AUTs) have been proposed as a mechanism for improving antimicrobial use, but data on their efficacy remain limited.
Objective.To determine the impact of an AUT on antimicrobial use at a teaching hospital.
Design.Randomized controlled intervention trial.
Setting.A 953-bed, public, university-affiliated, urban teaching hospital.
Patients.Patients who were given selected antimicrobial agents (piperacillin-tazobactam, levofloxacin, or vancomycin) by internal medicine ward teams.
Intervention.Twelve internal medicine teams were randomly assigned monthly: 6 teams to an intervention group (academic detailing by the AUT) and 6 teams to a control group that was given indication-based guidelines for prescription of broad-spectrum antimicrobials (standard of care), during a 10-month study period.
Measurements.Proportion of appropriate empirical, definitive (therapeutic), and end (overall) antimicrobial usage.
Results.A total of 784 new prescriptions of piperacillin-tazobactam, levofloxacin, and vancomycin were reviewed. The proportion of antimicrobial prescriptions written by the intervention teams that was considered to be appropriate was significantly higher than the proportion of antimicrobial prescriptions written by the control teams that was considered to be appropriate: 82% versus 73% for empirical (risk ratio [RR], 1.14; 95% confidence interval [CI], 1.04-1.24), 82% versus 43% for definitive (RR, 1.89; 95% CI, 1.53-2.33), and 94% versus 70% for end antimicrobial usage (RR, 1.34; 95% CI, 1.25-1.43). In multivariate analysis, teams that received feedback from the AUT alone (adjusted RR, 1.37; 95% CI, 1.27-1.48) or from both the AUT and the infectious diseases consultation service (adjusted RR, 2.28; 95% CI, 1.64-3.19) were significantiy more likely to prescribe end antimicrobial usage appropriately, compared with control teams.
Conclusions.A multidisciplinary AUT that provides feedback to prescribing physicians was an effective method in improving antimicrobial use.
Trial Registration.ClinicalTrials.gov identifier: NCT00552838.
