Enhanced Light Storage of SrAl2O4 Glass‐Ceramics Controlled by Selective Europium Reduction

A luminescent Eu, Dy: SrAl2O4 glass-ceramics with high transparency in the visible region was successfully synthesized using the frozen sorbet technique with the control of O2 partial pressure (PO2) for the oxidation of Eu2+ ions. The glass-ceramics include Eu2+, Eu3+, and Dy3+ ions, and thus exhibits three characteristic types of emission bands, 4f–5d at around 520 nm (Eu2+ ions), 4f–4f at 610 nm (Eu3+ ions), and 480 nm (Dy3+ ions). The Eu, Dy: SrAl2O4 glass-ceramics provide remarkable long-persistent luminescence under dark condition. The glass-ceramics also exhibits color-changing luminescence in the visible region based on their remarkable light storage properties. The luminescent Eu, Dy: SrAl2O4 glass-ceramics using the frozen sorbet technique with control of PO2 are promising materials for application in novel photonic and light storage materials.
Use of a Clinic-Based Skin Cancer Prevention Bundle to Promote Sun-Protective Behaviors in Patients at Moderate to High Risk for Skin Cancer

ABSTRACT Background Skin cancer is the most common type of cancer in the United States, and one in five Americans will develop a skin cancer at least once during their lifetime (U.S. Cancer Statistics Working Group, 2016). Analysis of current skin cancer prevention practices in a large academic university dermatology clinic revealed a lack of skin cancer risk stratification, targeted prevention messaging, and assessment of sun-protective behavior (SPB) use. An improvement project was initiated to evaluate the impact of a skin cancer prevention bundle (SCPB) on SPB use and sunburn frequency over a 2-month period. Methods Adult clinic patients 20–65 years old, at a moderate to high risk based on Brief Skin Cancer Risk Assessment Tool scores, received an SCPB consisting of personalized Brief Skin Cancer Risk Assessment Tool risk feedback, American Academy of Dermatology skin cancer prevention recommendations, and a brief American Academy of Dermatology skin cancer prevention video. A Sun Habits Survey and an assessment of perceived skin cancer risk were performed preintervention and postintervention. Results Thirty-eight participants (92.7%) completed the project. Outcome measures showing significant difference postintervention included Sun Protection Habits Index summary scores (p < .0001), sunburn frequency (p < .0001), and lifetime perceived risk of skin cancer (p = .007). Individual SPB habits of limiting midday ultraviolet exposure (p = .0004) and frequency of hat use (p = .01) also showed significant increases postintervention. Conclusions and Implications Use of the clinic-based SCPB improved SPB use and reduced sunburn frequency. The SCPB is being considered for clinic-wide implementation based on the findings. Further study with a larger number of participants and ongoing postclinic implementation evaluation is recommended to confirm results and fully assess the potential of the SCPB to improve patient outcomes and reduce skin cancer risk.
Precise Synthesis and Physicochemical Properties of High-Density Polymer Brushes designed with Poly(N-isopropylacrylamide)

A high-density polymer brush of poly(N-isopropylacrylamide) (PNIPA) was precisely prepared following carefully selected procedures, which included selecting the underlying substrate, preparing its surface, and grafting PNIPA on the substrate. As a result, the graft density and the dried thickness of the brush reached more than 0.5 chains/nm2 and 200 nm, respectively, for the best combination of each procedure. This high-density polymer brush showed gradual collapse with increasing temperature in water, which must be attributed to both the low swelling and the low shrinking abilities of the brush that result from the physically constrained state of the polymers. The contact angle of the air bubbles underneath the high-density polymer brush also gradually decreased up to around 25 °C in water with increasing temperature, which indicates that the hydrophilicity of the surface decreases as it does in typical PNIPA-grafted membranes and gels. Starting at the lower critical solution temperature of free PNIPA in.
Cyclic Oligolactic Acid in Direct Polycondensation PLLA and Its Extraction with Organic Solvent

The contents of poly(L-lactic acid) (PLLA) prepared by direct condensation polymerization without using a catalyst were studied. 1H NMR and mass spectrometry analyses suggested that PLLA contained cyclic oligo(L-lactic acid) (c-OLLA) with 3–20 repeat units. Notably, only c-OLLA was extracted and isolated using hexane or cyclohexane at 4°C; thus the hydrophobicity, topology, and temperature dependence of the solubility of the obtained PLLA enabled the selective extraction of c-OLLA. The effect of cyclic compounds on direct polycondensation and the potential for c-OLLA to form molecular inclusion complexes were also discussed.
A Scanning Electron Microscopy Study of a Calcium‐Polygalacturonate Network in the Presence of Aluminum: A Model to Investigate Soil‐Root Interface Processes

Abstract The objective of this study was to investigate the effects of aluminum (Al3+) on a calcium‐polygalacturonate (Ca‐PG) network used as a soil‐root interface model. Calcium‐PG networks were exposed to Al3+ solutions at different concentrations (100, 200, 400, and 800 µM) at pH 3.50. In the present study, the scanning electron microscopy technique was used to evaluate morphological variations induced by Al3+sorption. Results showed how aluminum (Al) sorption induces conformational changes of the Ca‐PG complex. The Ca‐PG complex shows a regular structure with a honeycomb‐like pattern. Interlacing fibrils form a porous system, which can easily allow sorption and/or passage of nutrients as well as toxic elements. As Al becomes the predominant reticulating ion, the pores decrease in size and lose their regular shape. The scanning electron micrographs have in fact shown that Al sorption damages the Ca‐PG complex, leading to its collapse; the Ca‐Al‐PG networks exhibit an irregular uneven structure.
Effect of Vermicompost on the Growth and Production Of Amashito Pepper, Interactions with Earthworms and Rhizobacteria

Increasing yield is one of the goals in the tropics. Traditional farming is replaced in many cases by agroindustrial production which often leads to environmental pollution due to the marked use of pesticides and fertilizers. In Tabasco, Amashito pepper (Capsicum annum var. glabriusculcum) is cultivated in the traditional way in backyards or cocoa fields with no chemical inputs. The germination of these kind of peppers is difficult to achieve, since wild peppers seeds have a large range of dormancy. Plant-growth-promoting rhizobacteria (PGPRs) are used as inoculants for biofertilization, phytostimulation and biocontrol. Soil fauna has an important function in regulating rhizosphere microbial processes and therefore significantly affects plant growth. Earthworms produce indirect effects through changes in the environment of the roots or via interactions with organisms that affect root growth and production. Our aim was to study the effects of different fresh organic matter, earthworms (P. corethrurus, oligochaeta) and rhizobacteria (A. brasiliensis) on plant growth, and yield production of amashito pepper (Capsicum annuum var. glabriusculum). We established a three factorial outdoors mesocosms experiment. We tested the effects of 3 substrates (dry cocoa husks (C), Panicum sp grass-cocoa husks vermicompost (V), cocoa husks with cow manure (CC) (type of germination substrate, factor 1), the presence (E) and absence of P. corethrurus (WE) (earthworm, factor 2) and the absence (WB) or presence (B) of A. brasiliensis (rizobacteria, factor 3). After 173 days, fruit production was significantly more in plants raised in vermicompost. Vermicompost significantly enhanced the highest weight (23.4g), height (26.7 cm) and production of leaves per plant (20.6 leaves per plant). Further studies are required in order to understand the interactions between vermicompost, plants, earthworms and rhizobacteria.
Applied-B field ion diode studies at 3.5 TW

The performance of 7 and 14 cm radius, applied B‐field, focusing ion diodes is investigated on the Proto II accelerator at a diode power of 3.5 TW. The ion production efficiency of the 14‐cm diode is determined to be approximately 80% for the 30‐ns power pulse used. When a 2 Torr air background gas was used in the beam propagation region between the diode and the target, the ion beam was observed to be approximately 70% magnetically neutralized in regions of approximately 20 kG transverse B‐field and ≥95% in regions of no B‐field. The local and global divergence of the 1.4‐MV beam were each determined to be approximately 1°. Local source power brightness of >1.5×1013 W/cm2/rad2 is inferred.
Conceptual modeling of the humic colloid-borne americium(III) migration by a kinetic approach

The humic colloid-borne Am(III) migration is investigated by laboratory experiment. As the reactions controlling the Am(III) migration are found to be not in equilibrium, the experimental results are interpreted by a kinetic model, i.e., the Kinetically Controlled Availability Model (KICAM). Model parameters determined by fitting experimental data in one groundwater sand system are applied (i) to describe the Am(III) sorption and migration behavior in three other groundwater sand systems with lower humic colloid concentrations and (ii) to calculate the recovery of modified column experiments with different column lengths. Further refinement and applicability of the laboratory calibrated model to a real system is considered briefly.
The Surface Structure of CaF2; A Comparison of Techniques

Abstract A nano-crystal of CaF2, consisting of 3645 ions, was simulated at 300 K for 110 ps using molecular dynamics. After this time, the structures of non-dipolar {111} and dipolar {200} surfaces showed features which were comparable to simulations carried out with a 2D energy minimisation code. Of particular interest was the similarity between defects that appeared on the {200} surface in the MD simulation and the lowest energy configurations determined in the static simulation.
Factors influencing stream chemistry in catchments on Prince of Wales Island, Alaska

1. Factors influencing the water chemistry of streams were evaluated for remote catchments on Prince of Wales Island, Alaska, a high-latitude geologically diverse landscape. 2. We evaluated the hypothesis that weathering rates of dominant geological formations of catchments would be the major factor influencing the water chemistry of streams. 3. Catchments were compared by synoptic sampling of stream and cave waters, mapping to define the distribution of geological formations, and laboratory studies of rock weathering. 4. Carbonation was identified as the major mechanism influencing the weathering of rocks. High Pco2 levels of cave and upwelling waters in streams suggested CO2, supplied by soil respiratory processes, was the major factor controlling the concentration of dissolved CO2, carbonic acid dissociation, and H+ replacement of cations on rock surfaces. 5. Additional evidence of carbonation included the relationship between HCO31– and Ca2+ + Mg2+ (r2 = 0.95) for low- and high-alkalinity waters. The relationship suggested that the high-alkalinity waters were associated with the weathering of calcareous rocks. Waters with high alkalinities (> 1254 μeq l–1), pH (> 7.0), Ca : Mg ratios (> 6.0.) and saturation values for Ca2+ (SIc = –0.59–0.06) indicated that karst (limestone) formations with calcite minerals were the major sources of calcium (> 1266 μeq l–1). Waters with the lowest alkalinity, pH, HCO31– and cation concentrations were associated with granodiorite (igneous) rocks. Laboratory studies substantiated these findings, with weathering being highest when waters contacted Heceta and Bay of Pillars limestone formations and lowest with igneous rocks. 6. Weathering of rocks, and possibly soils, appeared to be facilitated by surface and subsurface movements of CO2 and water through fractured karst formations, and water availability in rain-dominated forests. The proximity of the sea and sulphur in marine aerosols and rainfall, and sulphate reacting with water, may also supply hydrogen ions to weathering reactions. 7. This study provides a basis for developing a better understanding of the influences of surface–subsurface geological and hydrological factors, and climatic conditions, on stream chemistry and biota in high-latitude ecosystems.
PII: S0167-2789(01)00386-4

The study of complex systems consisting of many interacting subsystems requires the use of analytical tools which can detect statistical dependencies between time series recorded from these subsystems. Typical examples are the electroencephalogram (EEG) and magnetoencephalogram (MEG) which may involve the simultaneous recording of 150 or more time series. Coherency, which is often used to study such data, is only sensitive to linear and symmetric interdependencies and cannot deal with non-stationarity. Recently, several algorithms based upon the concept of generalized synchronization have been introduced to overcome some of the limitations of coherency estimates (e.g. [Physica D 134 (1999) 419; Brain Res. 792 (1998) 24]). However, these methods are biased by the degrees of freedom of the interacting subsystems [Physica D 134 (1999) 419; Physica D 148 (2001) 147]. We propose a novel measure for generalized synchronization in multivariate data sets which avoids this bias and can deal with non-stationary dynamics. © 2002 Elsevier Science B.V.

KangFuXinYe with epidermal growth factor on acute radiation enteritis

Objective: The present study is designed to observe the efficacy of KangFuXinYe combined with epidermal growth factor (EGF) on acute radiation enteritis. Methods: A total of 74 cases with acute radiation enteritis were divided into the observation group (n=37) and the control group (n=37) by using random number tables. The patients in the observation group were treated with KangFuXinYe and recombinant human epidermal growth factor, whereas the patients in the control group were subjected to KangFuXinYe. The main outcome measures were efficacy, efficacy under colonoscopy, transforming growth factor beta 1 in the serum, and interleukin (IL)-10. The secondary outcome measure was the quality of life (QOL). Results: The overall response rate of the observation group was higher than control group. The overall response rate of the former under colonoscopy was also higher than that of the latter. After the treatment, transforming growth factor beta 1 decreased, whereas IL-10 increased more evidently in the observation group. The 3-month QOL of the observation group was better than that of the control group in physiological function, physical role, social function, emotional role, and bodily pain. Conclusion: KangFuXinYe combined with EGF is effective in treating acute radiation enteritis, improving inflammation, promoting intestinal mucosal repair, and increasing QOL.

Unsupervised classification algorithms have been evaluated and examined for this purpose. The final outcomes revealed that a dramatic increase of the urban areas took place in the last years and as results significant pressure is expected on archaeological sites found in the periurban areas.
Lázaro: An Extractor of Emergent Anglicisms in Spanish Newswire A Master’s Thesis Presented to The Faculty of the Graduate School of Arts and Sciences Brandeis University Graduate Program in Computational Linguistics Department of Computer Science

Lázaro: An Extractor of Emergent Anglicisms in Spanish Newswire A thesis presented to the Faculty of the Graduate School of Arts and Sciences of Brandeis University Waltham, Massachusetts By Elena Álvarez-Mellado The use of lexical borrowings from English (often called anglicisms) in the Spanish press evokes great interest, both in the Hispanic linguistics community and among the general public. Anglicism usage in Spanish language has been previously studied within the field of corpus linguistics. Prior work has traditionally relied on manual inspection of corpora, with the limitations that implies. This thesis proposes a model for automatic extraction of unadapted anglicisms in Spanish newswire. This thesis introduces: (1) an annotated corpus of 21,570 newspaper headlines (325,665 tokens) written in European Spanish annotated with unadapted anglicisms and (2) two sequencelabeling models to perform automatic extraction of unadapted anglicisms: a conditional random field model with handcrafted features and a BiLSTM-CRF model with word and character embeddings. The best results are obtained by the CRF model, with an F1 score of 89.60 on the development set and 87.82 on the test set. Finally, a practical application of the CRF model is presented: an automatic pipeline that performs daily extraction of anglicisms from the main national newspapers of Spain.
ATCA Future Science Case: 2020 onwards

The Australia Telescope Compact Array (ATCA) is a radio interferometer with six 22m dishes operating across a wide frequency range from 1–105GHz and located near Narrabri, NSW. The ATCA has undergone regular upgrades since it began operation in 1988. Its broad frequency coverage is unique in the southern hemisphere, and several of its other capabilities are unmatched anywhere in the world. This document examines the science case for continued operation of the Australia Telescope Compact Array (ATCA) in the era after 2020 when the SKA precursor telescopes ASKAP and MeerKAT will be in full operation. SKA1-MID is not expected to start science operations until 2029-30. The key ATCA science areas from 2020 onwards are identified as:
Application of extended Kalman filter for estimation of periodic disturbance and velocity ripple reduction in PMSM drive

In this paper an application of extended Kalman filter (EKF) for estimation and attenuation of periodic disturbance in permanent magnet synchronous motor (PMSM) drive is investigated. Most types of disturbances present into PMSM drive were discussed and described. The mathematical model of the plant is presented. Detailed information about the design process of the disturbance estimator was introduced. A state feedback controller (SFC) with feedforward realizes the regulation and disturbance compensation. The theoretical analysis was supported by experimental tests on the laboratory stand. Both timeand frequency-domain analysis of the estimation results and angular velocity were performed. A significant reduction of velocity ripple has been achieved.
A straightforward click-approach towards pretubulysin-analogues

The [3+2]-cycloaddition of an azido tripeptide, corresponding to the left hand side of pretubulysin, with a range of alkynes, such as propiolic acid amides and propargyl ethers, allows the straightforward syntheses of libraries of tubulysin derivatives. Via this click approach, a chimera of pretubulysin and dolastatin 10, both highly potent antimitotic drug candidates, also becomes accessible.
Diffusion-Limited Mobilization and Transport of Natural Colloids in Macroporous Soil

This study examines the dynamics of colloid mobilization and leaching from macroporous soil columns by means of laboratory experiments and numerical modeling. On the basis of a previous column study involving high and low water flow rates in structured soil, we designed a novel experiment emphasizing the time-dependence of the colloid release process. Intact macroporous soil columns were exposed to variable pauses in irrigation (flow interruption for 30 min, 1 d, or 7 d) followed by resumed infiltration. The experiments showed that (i) there was a seemingly unlimited source of in situ colloids even after prolonged leaching and (ii) the peak concentration of colloids in the effluent after the flow interruption increased with increasing length of the preceding pause. The results demonstrated that colloid mobilization is not controlled by hydrodynamic shear induced by the flowing water but is a time-dependent and possibly diffusion-limited process. We developed a simple, equivalent macropore model to investigate the hypothesis that colloid release to the flowing water is governed by two diffusion processes, one in a uniform water film lining the macropore and one in the crust of the macropore. The model was capable of reproducing and explaining the characteristic results of our soil column experiments and required no recalibration of exchange process parameters to simulate the particle mobilization after a flow interruption. However, model calibration yielded unexpected results with respect to the size of the diffusion coefficient of the crust and did not warrant accepting the dual diffusion model hypothesis. Using a simpler mass transfer concept to quantify the mobilization of colloids in 21 soil columns, we found mass transfer coefficients to be about 30 times higher in the water film than in the crust.
Heart Rate Measurements in Patients with Obstructive Sleep Apnea and Atrial Fibrillation: Prospective Pilot Study Assessing Apple Watch’s Agreement With Telemetry Data

Background Patients with obstructive sleep apnea (OSA) are at a higher risk for atrial fibrillation (AF). Consumer wearable heart rate (HR) sensors may be a means for passive HR monitoring in patients with AF. Objective The aim of this study was to assess the Apple Watch’s agreement with telemetry in measuring HR in patients with OSA in AF. Methods Patients with OSA in AF were prospectively recruited prior to cardioversion/ablation procedures. HR was sampled every 10 seconds for 60 seconds using telemetry and an Apple Watch concomitantly. Agreement of Apple Watch with telemetry, which is the current gold-standard device for measuring HR, was assessed using mixed effects limits agreement and Lin’s concordance correlation coefficient. Results A total of 20 patients (mean 66 [SD 6.5] years, 85% [n=17] male) participated in this study, yielding 134 HR observations per device. Modified Bland–Altman plot revealed that the variability of the paired difference of the Apple Watch compared with telemetry increased as the magnitude of HR measurements increased. The Apple Watch produced regression-based 95% limits of agreement of 27.8 – 0.3 × average HR – 15.0 to 27.8 – 0.3 × average HR + 15.0 beats per minute (bpm) with a mean bias of 27.8 – 0.33 × average HR bpm. Lin’s concordance correlation coefficient was 0.88 (95% CI 0.85-0.91), suggesting acceptable agreement between the Apple Watch and telemetry. Conclusions In patients with OSA in AF, the Apple Watch provided acceptable agreement with HR measurements by telemetry. Further studies with larger sample populations and wider range of HR are needed to confirm these findings.
