NDVI‐based estimates of evapotranspiration of winter wheat indicate positive effects of N fertilizer application on agronomic water‐use efficiency
Authors: Drerup Philipp , Brueck Holger , Eticha Dejene , Scherer Heinrich W. 
Published: October 2019

AbstractYield increases by fertilizer application impose higher crop water use, as biomass production is positively correlated with transpiration. To quantify effects of N fertilizer supply on evapotranspiration (ET) of winter wheat, a field experiment with three nitrogen rates (N0, N120 and N230) under non‐water‐limited conditions was performed during 2014 and 2015. Normalized difference vegetation index (NDVI) was used to derive crop coefficients which were used to calculate N effects on bare soil evaporation (E), transpiration, evapotranspiration (ET), grain yield and harvest index (HI). E during the early post‐winter growth period was measured with micro‐lysimeters and compared with model estimates. N fertilizer supply resulted in lower cumulative E, and increases in grain yield were higher than increases in ET, resulting in a higher agronomic water‐use efficiency (WUEY). HI of treatment N120 was higher than that of treatment N230 indicating that HI was not the main reason of higher WUEY of treatment N230. It is concluded that estimates of ET under variable N supply require consideration of N‐induced effects on canopy development which could be successfully monitored by NDVI measurements. N supply increases ET and WUEY potentially imposing a trade‐off between water conservation and efficiency of water use for crop production.

AbstractIn order to avoid the property degradation resulting from high‐temperature joining process, nano‐infiltrated transient eutectoid (NITE) phase with the Al2O3‐Ho2O3 as the joining adhesives was adopted to join silicon carbide (SiC) ceramics with the attempts to lower down the joining temperature. The liquid‐phase‐sintered silicon carbide (LPS‐SiC) specimens were joined at 1500‐1800°C by spark plasma sintering (SPS) under the pressure of 20 MPa. The results of the shear test and microstructure observation showed that the joining process could be finished at a relatively lower temperature (1700°C) compared to other NITE‐phase joining. In contrast to the shear strength of 186.4 MPa derived from the SiC substrate, the joint exhibited the shear strength of 157.8 MPa with the fully densified interlayer.

AbstractOptical properties of lead‐free ferroelectric pure and Mn‐doped 0.92Na0.5Bi0.5TiO3‐0.08K0.5Bi0.5TiO3 (NBT‐8KBT) single crystals have been investigated systematically. Refractive index and extinction coefficient were measured and the critical parameters are obtained by modified Sellmeier dispersion equations and single‐oscillator dispersion relation. The decline of refractive index for Mn:NBT‐8KBT could be related to the lattice distortion of the Mn ions doping. High transmittance (>70%) over the transparent region (>400 nm) was found in the pure NBT‐8KBT, higher than that of Mn:NBT‐8KBT, which could be caused by the increase of domain wall density. An about 100 nm red‐shift of absorption edge was observed in the Mn:NBT‐8KBT single crystal, which is located in the visible region. Optical bandgap energies calculated through Tauc equation and a large bandgap difference of 2.96 and 2.62 eV occurs in the NBT‐8KBT and Mn:NBT‐8KBT, respectively, which illustrates the modulation of the band structures by Mn doping.

Published: October 2019

AbstractRenal cell carcinoma (RCC) is a heterogeneous histological disease and it is one of the most common kidney cancer. The treatment of RCC has been improved for the past few years, but its mortality still remains high. Chelerythrine (CHE) is a natural benzo[c]phenanthridine alkaloid and a widely used broad‐range protein kinase C inhibitor which has anti‐cancer effect on various types of human cancer cells. However, its effect on RCC has not been fully elucidated. In this study, we evaluated the effect and mechanism of CHE on RCC cells. Our study showed that CHE induced colony formation inhibition and G2/M cell cycle arrest in a dose‐dependent manner in RCC cells. In addition, CHE increased cellular ROS level, leading to endoplasmic reticulum (ER) stress, inactivating STAT3 activities and inducing apoptosis in RCC cells which were suppressed by NAC, a special ROS inhibitor. We further found that both knockdown of ATF4 protein and overexpression of STAT3 protein could reduce CHE‐induced apoptosis in Caki cells. These results demonstrated that the apoptosis induced by CHE was mediated by ROS‐caused ER stress and STAT3 inactivation. Collectively, our studies provided support for CHE as a potential new therapeutic agent for the management of RCC.

Published: October 2019

AbstractThe transient receptor potential melastatin‐related 2 (TRPM2) channel, a reactive oxygen species (ROS)‐sensitive cation channel, has been well recognized for being an important and common mechanism that confers the susceptibility to ROS‐induced cell death. An elevated level of ROS is a salient feature of ischaemia‐reperfusion, chronic cerebral hypo‐perfusion and neonatal hypoxia‐ischaemia. The TRPM2 channel is expressed in hippocampus, cortex and striatum, the brain regions that are critical for cognitive functions. In this review, we examine the recent studies that combine pharmacological and/or genetic interventions with using in vitro and in vivo models to demonstrate a crucial role of the TRPM2 channel in brain damage by ischaemia‐reperfusion, chronic cerebral hypo‐perfusion and neonatal hypoxic‐ischaemia. We also discuss the current understanding of the underlying TRPM2‐dependent cellular and molecular mechanisms. These new findings lead to the hypothesis of targeting the TRPM2 channel as a potential novel therapeutic strategy to alleviate brain damage and cognitive dysfunction caused by these conditions.

Authors: Mathur M. , Acharya P. 
Published: October 2019

AbstractTrichoscopy is an emerging technique for the evaluation of various hair and scalp disorders including primary cicatricial alopecias (PCAs). Early diagnosis of PCAs can lead to effective management and trichoscopy could be a useful aid during this process. Multiple studies have reported the trichoscopic features of PCAs, however, a focused review evaluating these disorders with their trichoscopic features is lacking. With the objective of evaluating the trichoscopic findings reported in the literature for various PCAs, we conducted a systematic literature search in PubMed and Embase. The search yielded 310 studies in a total of which 54 studies were included in our review. Majority of these studies originated from the Caucasian or Asian population. Through this review, we provide an overview of the frequent and specific trichoscopic findings in different PCAs with their clinical significance where applicable based on the current knowledge and identify the areas for future research.

AbstractBackgroundIn previous epidemiological study, the prevalence of atopic dermatitis (AD) was 12.94% among children aged 1–7 years by clinical diagnosis, whereas that was 4.76% and 3.51% using U.K., and Hanifin and Rajka diagnostic criteria.ObjectiveWe aimed to propose new diagnostic criteria for children and evaluate its efficiency in different populations.MethodsWe screened atopic features and analysed their correlation with AD using data from a previous study. A new set of diagnostic criteria for children in China was proposed and validated in 1031 children in outpatient clinics and 538 children in a birth cohort survey. Clinical diagnosis and atopic feature evaluation were performed face to face by dermatologists specialized in AD. Three criteria were compared for diagnostic efficiency using the clinical diagnosis as the reference.ResultsThe new diagnostic criteria for children were based on (i) pruritus; (ii) ‘typical morphology and distribution’ or ‘atypical morphology and distribution with xerosis’; and (iii) a chronic or chronically relapsing course. Compared to classical diagnostic criteria, the sensitivity of the new diagnostic criteria was significantly higher in the epidemiological survey and the clinical setting, especially obvious among mild and moderate AD. In the birth cohort, the new criteria showed similar sensitivity and specificity.ConclusionThe new criteria for children yielded higher sensitivity for the diagnosis of AD in the epidemiological survey and clinical setting, particularly for mild and moderate AD. Among the birth cohort with a complete medical history, three criteria showed similar sensitivity and specificity.
Comparing the Accuracy of Student Growth Measures
Authors: Castellano Katherine E. , McCaffrey Daniel F. 
Published: October 2019

AbstractTesting programs are often interested in using a student growth measure. This article presents analytic derivations of the accuracy of common student growth measures on both the raw scale of the test and the percentile rank scale in terms of the proportional reduction in mean squared error and the squared correlation between the estimator and target. The study contrasts the accuracy of the growth measures against that of current status measures—current test scores and their percentile ranks. Key findings include the extent that status measures are more accurate than any of the growth measures and that alternative methods to estimate growth could be more accurate than the currently used methods. Our findings highlight the importance for evaluating the statistical properties of growth measures along with other concerns for states that are debating the reporting of growth. Our results also point out that assessing the accuracy of growth measures requires the specification of quantities of interest in terms of latent achievement rather than observed test scores, which is common practice for developing status measures but essentially never done by testing programs for growth measures.
Improving Item‐Exposure Control in Adaptive Testing
Authors: van der Linden Wim J. , Choi Seung W. 
Published: October 2019

AbstractOne of the methods of controlling test security in adaptive testing is imposing random item‐ineligibility constraints on the selection of the items with probabilities automatically updated to maintain a predetermined upper bound on the exposure rates. Three major improvements of the method are presented. First, a few modifications to improve the initialization of the method and accelerate the impact of its feedback mechanism on the observed item‐exposure rates are introduced. Second, the case of conditional item‐exposure control given the uncertainty of examinee's ability parameter is addressed. Third, although rare for a well‐designed item pool, when applied in combination with the shadow‐test approach to adaptive testing the method may meet occasional infeasibility of the shadow‐test model. A big M method is proposed that resolves the issue. The practical advantages of the improvements are illustrated using simulated adaptive testing from a real‐world item pool under a variety of conditions.
Age‐based life history of humpback red snapper, Lutjanus gibbus, in New Caledonia
Authors: Moore Bradley R. 
Published: October 2019

AbstractThis paper examines the life history of humpback red snapper Lutjanus gibbus, an important fishery species for coastal communities across the Indo‐Pacific, in southern New Caledonia, where the species is lightly exploited. A total of 243 L. gibbus were sampled between January 2013 and December 2016 from occasional harvests of commercial fishers. Examination of sectioned otoliths revealed that opaque increment formation occurred annually between November and March, coinciding with the species' spawning season. Estimates of maximum age were similar between sexes, with observed ages of 38 and 36 years for females and males, respectively, extending the reported longevity of this species by at least 11 years. Growth differed significantly between sexes, with males reaching greater length at age and greater asymptotic length than females (38.88 v. 31.46 cm fork length (LF). Total mortality for all samples was estimated as 0.13 and was slightly higher for males (0.16) than females (0.11). Estimates of natural and fishing mortality were low and slightly higher for males than females. Male L. gibbus were found to mature at slightly greater lengths and younger ages than females, with the length and age at which 50% of individuals attained maturity estimated to be 25.8 cm LF and 3.9 years of age for females and 26.8 cm LF and 3.4 years of age for males. The results provide key baseline information from which to assess the effect of fishing on the species for populations in New Caledonia and adjacent locations and, when viewed with those of other studies, highlight the importance of understanding spatial patterns in demography of harvested fish species across gradients of exploitation and environmental influences.

Published: October 2019

IntroductionExposure to childhood abuse or neglect may lead to negative outcomes during pregnancy in expecting parents, which may contribute to a negative experience of childbearing and have consequences for the developing fetus. This study examined the associations between exposure to childhood abuse or neglect, psychological symptoms, prenatal attachment, and perception of parental competence in expectant parents.MethodsIndividuals at low sociodemographic risk were recruited in community perinatal care settings and completed self‐report assessment measures of depression, posttraumatic stress disorder, dissociation, personality disorders, perception of parental competence, and prenatal attachment.ResultsThere were 322 participants (78% women), including 91 adults with a history of childhood abuse or neglect, Participants who were exposed to childhood abuse or neglect reported significantly higher levels of symptoms on all indices of mental health than nonexposed adults, even when controlling for sociodemographic risks. However, both groups reported similar levels of prenatal attachment and parental confidence. The impact of childhood maltreatment was similar in men and women. Structural equation modeling showed that childhood abuse or neglect leads to poor mental health and that poor mental health, but not childhood maltreatment, is associated with low parental confidence and prenatal attachment.DiscussionPsychological symptoms are frequent in expectant parents who experienced maltreatment during their childhood. However, childhood abuse or neglect is not associated with their attitude regarding parenthood and the child in the absence of psychopathology. Supporting mental health may be an important target of parental programs offered during pregnancy to women and men with a history of childhood abuse or neglect.

ABSTRACTBACKGROUND AND PURPOSECerebral vasodilatory capacity assessment for risk stratification in patients with extracranial arterial stenosis or occlusion may be useful. We describe a new method that assesses cerebral vasodilatory capacity as part of catheter‐based cerebral angiography.METHODSWe prospectively assessed regional cerebral blood volume (rCBV) in the arterial distribution of interest using a controlled contrast injection in the common carotid or the subclavian arteries. rCBV maps were created using a predefined algorithm based on contrast distribution in the venous phase (voxel size: .466 mm3). rCBV maps were acquired again after selective administration of intra‐arterial nicardipine (2.0 mg) distal to the stenosis. Two independent observers graded the change in rCBV in 10 predefined anatomical regions within the tributaries of the artery of interest (0 = reduction, 1 = no change, 2 = increase) and total rCBV change scores were summated.RESULTSTwenty‐five patients with internal carotid artery stenosis (n = 18; 0‐90% in severity) or extracranial vertebral artery stenosis (n = 7; 0‐100% in severity) were assessed. There was an increase in rCBV in a tributary of the artery of interest in 18 of 25 after intra‐arterial nicardipine (mean score: 11.98; range 0‐19.5). There was no change or decrease in rCBV in 7 of 25 patients. The mean rCBV change score was similar in patients with an assessment of internal carotid artery or vertebral artery distributions (12.2 ± 5.3; 11.4 ± 2.5; P = .68).CONCLUSIONSelective vasodilatory response to intra‐arterial nicardipine in the affected arterial distribution during catheter‐based cerebral angiography may provide new data for risk stratification.

AbstractPurposeTo evaluate the effect of different wax pattern fabrication techniques on the fit of customized pressed lithium disilicate implant abutments on titanium inserts before and after pressing. The marginal fit results of pressed lithium disilicate implant abutments were then compared with those of milled lithium disilicate abutments.Materials and MethodsAfter scanning the titanium inserts and designing an implant abutment, wax patterns were fabricated with three techniques (n = 15 each): computer‐aided design/computer‐aided manufacturing (CAD/CAM) milling, 3D printing and conventional layering. The marginal fit (µm) was measured using a stereomicroscope for all the wax patterns before pressing them into the lithium disilicate abutments. The pressed implant abutments were measured again for marginal fit, and the results were compared to those of the milled lithium disilicate abutments. One‐way analysis of variance (ANOVA) was used to assess different wax pattern fabrication techniques in each stage before and after pressing. One‐way ANOVA was also used to compare the groups of pressed and milled lithium disilicate abutments. Multiple pairwise comparisons were performed using the Tukey post hoc test in each stage.ResultsThere were statistically significant differences between the marginal fit of the three wax patterns groups (p < 0.001; f = 123.33), wherein the mean marginal fit was the highest for conventionally layered wax patterns (30 ± 13.09) µm. Furthermore, after pressing, there were statistically significant differences between the marginal fit of the three pressed abutments groups (p < 0.001; f = 518.62), wherein the mean marginal fit was the highest for pressed e.max abutments fabricated from conventionally layered wax patterns (25.26 ± 3.9) µm. There was no statistically significant difference between the mean marginal fit of the pressed abutments fabricated from conventional layered wax patterns and that of the milled CAD/CAM abutments. However, the mean marginal fit of the milled CAD/CAM abutments was higher than that of the pressed abutments fabricated from both CAD/CAM wax and 3D printed wax.ConclusionAll the tested fabrication methods provided degrees of accuracy that lie well within accepted limits. The use of pressed lithium disilicate abutments fabricated from conventional layering wax pattern technique should provide a more consistent better marginal fit between the titanium insert and the abutment and may therefore be the preferable fabrication method.

Published: October 2019

Commercially available wearable devices are marketed as a means of objectively capturing daily sleep easily and inexpensively outside of the laboratory. Two ecological momentary assessment studies—with 120 older adolescents (aged 18–19) and 395 younger adolescents (aged 10–16)—captured nightly self‐reported and wearable (Jawbone) recorded sleep duration. Self‐reported and wearable recorded daily sleep duration were moderately correlated (r ~ .50), associations which were stronger on weekdays and among young adolescent boys. Older adolescents self‐reported sleep duration closely corresponded with estimates from the wearable device, but younger adolescents reported having an hour more of sleep, on average, compared to device estimates. Self‐reported, but not wearable‐recorded, sleep duration and quality were consistently associated with daily well‐being measures. Suggestions for the integration of commercially available wearable devices into future daily research with adolescents are provided.
