Performance of the Adriatic early warning system during the multi-meteotsunami event of 11–19 May 2020: an assessment using energy banners
Authors: Tojčić Iva , Denamiel Cléa , Vilibić Ivica 
Published: August 2021

Abstract. This study quantifies the performance of the Croatian
meteotsunami early warning system (CMeEWS) composed of a network of air
pressure and sea level observations, a high-resolution atmosphere–ocean
modelling suite, and a stochastic surrogate model. The CMeEWS, which is not
operational due to a lack of numerical resources, is used retroactively to
reproduce the multiple events observed in the eastern Adriatic between
11 and 19 May 2020. The performances of the CMeEWS
deterministic models are then assessed with an innovative method using
energy banners based on temporal and spatial spectral analysis of the
high-pass-filtered air pressure and sea level fields. It is found that
deterministic simulations largely fail to forecast these extreme events at
endangered locations along the Croatian coast, mostly due to a systematic
northwestward shift of the atmospheric disturbances. Additionally, the use
of combined ocean and atmospheric model results, instead of atmospheric
model results only, is not found to improve the selection of the transects
used to extract the atmospheric parameters feeding the stochastic
meteotsunami surrogate model. Finally, in operational mode, the stochastic
surrogate model would have triggered the warnings for most of the observed
events but also set off some false alarms. Due to the uncertainties
associated with operational modelling of meteotsunamigenic disturbances, the
stochastic approach has thus proven to overcome the failures of the
deterministic forecasts and should be further developed.

Alloying is an important way to increase the diversity of material structure and properties. In this paper, we start from Ising model considering nearest neighbor interaction, in which a ferromagnetic system corresponds to a low temperature phase separation and high temperature solid solution of binary alloy, while antiferromagnetic system corresponds to a low temperature ordered solid solution and a high temperature disorder. The high-throughput first-principles calculation based on the structure recognition is realized by the program SAGAR (structures of alloy generation and recognition) developed by our research group. By considering the contribution of structural degeneracy to the partition function, theoretical prediction of alloy materials can be carried out at finite temperature. Taking hydrogen storage alloy (Sc<sub><i>x</i></sub>Y<sub>1–<i>x</i></sub> Fe<sub>2</sub> and V<sub>2<i>x</i></sub> Fe<sub>2(1–<i>x</i>)</sub>Zr) for example, the formation energy of ground state (at zero temperature) can be obtained by the first-principles calculations. It is found that the formation energy of Sc<sub><i>x</i></sub>Y<sub>1–<i>x</i></sub> Fe<sub>2</sub> is greater than zero, thereby inducing the phase separation at low temperature. The free energy will decrease with the temperature and concentration increasing, where the critical temperature of solid solution of alloy is determined according to the zero point of free energy. The formation energies of V<sub>2<i>x</i></sub> Fe<sub>2(1–<i>x</i>)</sub>Zr are all lower than zero, and the ordered phase occurs at low temperature. The order-disorder transition temperature of V<sub>0.5</sub>Fe<sub>1.5</sub>Zr and V<sub>1.5</sub>Fe<sub>0.5</sub>Zr are both about 100 K, while the transition temperature of VFeZr is nearly 50 K. The calculation process will effectively improve the high throughput screening efficiency of alloy, and also provide relevant theoretical reference for experimental research.
Meta-analysis of differences in sleep quality based on actigraphs between day and night shift workers and the moderating effect of age
Authors: Chang Wen-Pei , Peng Yu-Xuan 
Published: August 2021

Abstract

Objectives
This study was to conduct a meta-analysis of studies that used actigraphs to compare the influence of day and night shifts on the sleep quality of workers as well as examine the moderating effect of age.

Methods
Databases including PubMed, CINAHL, the Cochrane Library, MEDLINE, and EBSCOhost were searched for relevant studies published in English between January 1st, 2000 and April 30st, 2021. Our main targets were studies that used actigraphs to assess the sleep quality of night shift workers. This meta-analysis included 12 papers and was performed using Comprehensive Meta-Analysis (CMA) Version 3.0. Effect sizes were displayed in a forest plot using standardized mean difference (SMD) and 95% confidence intervals (CI).

Results
Among the sleep quality indices of the day and night shift workers, no significant difference existed in terms of sleep efficiency (SE) (SMD = 0.27, 95% CI: −0.03-0.57), whereas night shift workers presented longer sleep-onset latency (SOL) (SMD = 0.62, 95% CI: 0.15-1.08), greater wake after sleep onset (WASO) (SMD = 0.41, 95% CI: 0.12-0.70), and longer total sleep time (TST) (SMD = 0.85, 95% CI: 0.32-1.39) than did day shift workers. The differences between the day and night shift workers in SOL, WASO, and TST did not vary with age.

Conclusions
Among the sleep quality indices, night shift workers presented longer SOL and greater WASO than did day shift workers. However, night shift workers could regulate their rest time and had adequate TST; thus, their SE was not different from that of day shift workers.
Addressing fatigue in medical residents with biomathematical fatigue modeling

Published: August 2021

Abstract
Fatigue in resident physicians has been identified as a factor that contributes to burnout and a decline in overall wellbeing. Fatigue risk exists because of poor sleep habits and demanding work schedules that have only increased due to the COVID-19 pandemic. At this time, it is important not to lose sight of how fatigue can impact residents and how fatigue risk can be mitigated. While fatigue mitigation is currently addressed by duty hour restrictions and education about fatigue, Fatigue Risk Management Systems (FRMSs) offer a more comprehensive strategy for addressing these issues. An important component of FRMS in other shiftwork industries, such as aviation and trucking, is the use of biomathematical models to prospectively identify fatigue risk in work schedules. Such an approach incorporates decades of knowledge of sleep and circadian rhythm research into shift schedules, taking into account not just duty hour restrictions but the temporal placement of work schedules. Recent research has shown that biomathematical models of fatigue can be adapted to a resident physician population and can help address fatigue risk. Such models do not require subject matter experts and can be applied in graduate medical education program shift scheduling. It is important for graduate medical education program providers to consider these alternative methods of fatigue mitigation. These tools can help reduce fatigue risk and may improve wellness as they allow for a more precise fatigue management strategy without reducing overall work hours.
Identification and characterization of glycosyltransferases catalyzing direct xanthone 4‐C‐glycosylation in Hypericum perforatum

Published: August 2021

Xanthones are compounds with a diphenyl ether skeleton mainly found in plants and often glycosylated at carbon atoms. Although many C‐glycosyltransferases (CGTs) participating in flavone C‐glycosylation have been identified, MiCGT from Mangifera indica, adding sugar to an open‐chain benzophenone skeleton, is the only identified xanthone biosynthesis‐related CGT. Here, we identified two CGTs from Hypericum perforatum that add sugar to the closed‐ring xanthone, but not benzophenone. These CGTs catalyze sugar transfer to the C‐4 position of norathyriol (1,3,6,7‐tetrahydroxyxanthone) to form isomangiferin (1,3,6,7‐tetrahydroxyxanthone 4‐C‐glucoside), a major xanthone C‐glucoside. This is the first study to report CGTs that mediate the direct C‐glycosylation of xanthone.

Published: August 2021

SummaryThis article presents a design strategy and stability analysis of modified repetitive sliding mode controller for uncertain linear systems. A modified repetitive controller is adopted to simultaneously track and reject periodic signals. A discrete‐time sliding mode controller is combined to compensate the slow response of repetitive control and to provide robustness against plant parameters uncertainties. Stability analysis is provided to prove boundedness of the proposed control law and the convergence of sliding function and the tracking error. Comparative simulation results demonstrate that the proposed method is able to accurately track reference signal and to reject disturbance with fast transient response. The results also indicate that the closed‐loop system remains stable in the presence of plant parameter changes.
Superhydrophobic and Conductive Cotton Fabric Composite with Excellent Corrosion Resistance for Wearable Electronics

Published: August 2021

AbstractHerein, a superhydrophobic and highly conductive cotton fabric (CF) composite with outstanding corrosion resistance for wearable textile electronics is developed. The fabrication process of the fabric composite involves spraying deposition and electrodeposition. Ag nanoparticles (AgNPs) are first synthesized on cotton fibers surface via two components spraying, forming cotton fibers core/AgNPs shell structure. The CF/AgNPs composite is then covered with a layer of cerium myristate (CeM) by electrodeposition, which endows the composite with superhydrophobicity and outstanding corrosion resistance. The resistivity of CF/AgNPs/CeM composite could reach as low as 0.106 Ω mm. Moreover, the obtained CF/AgNPs/CeM composite exhibits excellent self‐cleaning property and superhydrophobicity with a contact angle (CA) of 158.4°. Also, it maintains superhydrophobicity (CA > 150°) after 60 cm abrasion test or immersion in strong acidic/alkaline solution (pH = 1 or 13) for 24 h. In addition, the corrosion current density of conductive fabric composite (CFC) after electrodeposition decreases to 4.79% of the original value in simulated sweat corrosive media, suggesting a significant improvement of anti‐corrosion. The developed superhydrophobic CFC with excellent corrosion resistance and self‐cleaning performance has promising applications for wearable electronics in harsh conditions.
Photoinduced Superhydrophilic TiO2–PHEA/PS Photonic Crystal Composites with Vivid Structural Color, Self‐Cleaning Ability, and Robust Structure

Published: August 2021

AbstractDue to its high refractive index, photocatalytic activity, and photoinduced superhydrophilicity, TiO2 has advantages in photonic crystals (PCs). However, the composite of TiO2 and PCs needs to be calcined at high temperatures, and the structural stability of the composites is poor. In this study, photoinduced superhydrophilic TiO2–poly(hydroxyethyl acrylate)/polystyrene (PHEA/PS) PC composites with strong structural colors and self‐cleaning are fabricated by coating triethanolamine‐modified anatase TiO2 nanoparticles‐hydroxyethyl acrylate on the surface of PS PCs. The ordered arrays can be retained after the superficial layers of PS PCs are filled with TiO2–PHEA, and vivid blue, green, and red composites can be obtained. The water contact angles of the composites can be reduced to 3° in 0.4 s, and superhydrophilicity can be maintained for 180 days in a laboratory environment. The declining superhydrophilicity can be restored under UV irradiation. The composites can degrade the adsorbed methylene blue under UV irradiation. Photocatalytic activity and superhydrophilicity impart self‐cleaning ability on the composites. The locking of PS arrays by TiO2–PHEA enhances the structural stability of the composites, making them resistant to water soaking and washing. Therefore, the composites show prospects for decoration, fabric coloring, and wearable electronic devices.

AbstractTheo‐hydroxyphenyl ethyl ketone skeleton is prevalent in many biologically active natural products and active pharmaceutical ingredients. Herein, a two‐step protocol has been developed for synthesis of variousβ‐substitutedo‐hydroxyphenyl ethyl ketones. A base‐mediated ring opening of 4‐chromanone was used to introduce theβ‐ethoxylo‐hydroxyphenyl ethyl ketone intermediary, followed by nucleophile substitution under BF3 ⋅ Et2O assisted conditions to give the desiredβ‐carbon, nitrogen, or thiol substitutedo‐hydroxyphenyl ethyl ketones. With the aid of this protocol, a silica‐supported cobalt(II) salen complex was successfully prepared and its structure was confirmed by FTIR,13C MAS NMR, UV‐Vis absorption, and XPS spectra. The immobilized cobalt(II) salen catalyst not only displayed comparable catalytic activity in the synthesis of several heterocycles including 1,3‐oxazolidine, benzimidazole, and benzoxazole as compared with their homogeneous counterparts, but also could be recycled for several times without obvious loss of its catalytic activity.magnified image
Nonchlorinated Solubility Enhanced by Lipophilicity: An Effective Strategy for Environmentally Benign Processing of Rigidly Regular n‐type Polymeric Semiconductors

Published: August 2021

AbstractApplication of high‐performance unipolar n‐type polymeric semiconductors lagged behind due to those polymers’ poor solubility in green solvents. Traditional methods, such as random copolymerization and asymmetric structuring, enhance solubility but reduce mobility. Here, a universal “lipophilicity strategy” for eco‐friendly processing is reported. This strategy could effectively improve the solubility of polymers without sacrificing crystallinity thus maintaining good mobility of the devices. CF3 group and SCF3 group, which are famous for their high lipophilicity, are introduced to (E)‐1,2‐di(thiophen‐2‐yl)ethane (TVT). The solubility of two monomers is confirmed to be 5 and 16 times higher than the brominated counterpart, respectively. Moreover, CF3TVT and SCF3TVT not only improve solubility of the polymers but also reduce energy levels of donor unit due to their strong electron withdrawing property. By using Ozawa's condition, three unipolar n‐type semiconducting polymers are obtained through direct (hetero)arylation polycondensation (DHAP). Among them, CF3TVT based P2 processed by xylene solutions exhibited the best unipolar n‐type mobility up to 1.37 cm2 V−1 s−1 and reached current on/off ratio of 108, for the first time realizing both green synthesis and nonchlorinated processing. In general, this lipophilicity strategy provides an effective guideline to design high‐performance n‐type polymer with good solubility in nonchlorinated solvents.
Monolithic Multi‐Color Tunable Inorganic Light‐Emitting Diodes

Published: August 2021

AbstractInorganic light‐emitting diodes (LEDs) possess exceptional advantages for achieving wide wavelength emission ranges. However, certain material limitations should be overcome to alleviate the green gap between InGaN and AlInGaP‐based LEDs. In this study, monolithic red, green, and bluish‐green emissions are achieved by exploiting the blueshift phenomenon, caused by the band‐filling and piezoelectric screening effects. Different‐sized LEDs are designed to control the injection current density on the same wafer. The smaller the size of the LED, the shorter the emission wavelength, resulting in multi‐color emission (from red to bluish‐green). As a result, red, green, and white emissions are individually and simultaneously obtained using dichromatic LED systems, comprising three red and one green LED cell. In addition, a wide range of visible light colors are achieved by adjusting the size of the LEDs and the applies injection current.
