Authors: Pernamasari Rieke , . Sugiyanto 
Published: May 2022

Purpose: One of the most popular types of securities in the capital market is stock securities. Stocks that are considered good are stocks that are able to provide realized returns that are not too far from the expected returns, which are reflected in future stock prices. Through information asymmetry, it is expected to see the magnitude of the influence of earnings management on stock prices in the future. The purpose of this study is to examine the effect of earnings management on stock prices in the future with asymmetry as a moderating variable.
Methods: The method used in this study is a quantitative analysis method with cross-sectional data, using secondary data in the form of financial statements of consumption sector manufacturing companies listed on the Indonesia Stock Exchange (IDX) from 2015 to 2019, with analytical tools using SPSS.22
Findings: The higher the information asymmetry, the greater the bid-ask spread, in this case, the disclosure of earnings (ROA) in the financial statements is expected to reduce information asymmetry so that the bid-ask spread also decreases which leads to an increase in stock prices the future.
Novelty: The higher the information asymmetry, the greater the bid-ask spread, in this case, the disclosure of earnings (ROA) in the financial statements is expected to reduce information asymmetry so that the bid-ask spread also decreases which leads to an increase in stock prices the future.

Authors: Vala K. V. 
Published: May 2022

This paper reports a review based study into the two stage indirect- direct evaporative cooling technology, which is referred as two-stage evaporative cooling (TSEC) system. The direct-type (evaporative) cooling system is widely using natural cooling technology for storage of agricultural produce particularly fruits and vegetables because of its simplicity, eco-friendly and low-cost. But EC system is environment based and got the limitation that cooling of air can be done up to wet bulb temperature. To overcome this and owing to the continuous progress in cooling technology innovations are done by combining other indirect methods with direct type evaporative cooling system. Such system is known as two stage evaporative cooling, includes indirect and direct type cooling system. The indirect cooling has potential to be an alternative to conventional mechanical vapour compression refrigeration system to take up the air conditioning duty. Indirect cooling system is mostly heat exchanger(s) whereas direct cooling is wet pad type system. Combination of these two systems has obtained significantly enhanced cooling performance, with near to 90% and high energy efficiency ratio up to 80. The experimental and research work done on the indirect and direct cooling technology on the basis of their design, structural, type of indirect cooler, materials of construction, pad materials, effectiveness and energy saving have been reviewed and presented. This review paper explains the working principles of two-stage evaporative cooling systems and its performance assessed. This system is energy efficient, environment friendly and having potential for cooling and storage of fruits and vegetables in countries where hot and dry weather prevails for most of the part.

The study aimed to understand and study the effect of commercial seaweed extract and other biofertilizers on the yield attributes and economics of cultivated sweet corn. The biofertilizers were applied as seed inoculants and seaweed extract was applied as foliar spray. Totally nine combination treatments were evaluated for their performance on the growth and yield of sweet corn and revealed that green cob yield (10.58 t/ha and plant height 145.99 cm at harvest ) was found to be significantly higher in treatment combination Azospirillum @10 gm/kg + PSB @10 gm/kg +5.0% Seaweed extract and was on par with Azospirillum @20 gm/kg +5.0% Seaweed extract (9.61 t/ha, plant height 143.01 cm). Cobs/plant, grains rows/cob, grains /cob and grains/row were also found highest in the treatment Azospirillum @10 gm/kg + PSB @10 gm/kg +5.0% Seaweed extract. Similarly with respect to stover yield and higher harvest index (34.50%) was noticed in PSB @20 gm/kg +10% Seaweed extract which was followed by Azospirillum @10 gm/kg + PSB @10 gm/kg +5.0% Seaweed extract (34.40%). The benefit cost ratio was highest in the treatment Azospirillum @10 gm/kg + PSB @10 gm/kg +5.0% (2.77) and lowest B:C ratio (1.2) was obtained in the PSB @20 gm/kg + water spray. These findings indicate that seaweed extract can generally be used as a safe potential multifunctional biofertilizer in the agricultural field. The use of seaweed and biofertilizer could potentially help mitigate the adverse effects of main nutrient deficiencies, diminishing the use of chemical fertilizers.

Authors: Çelik Berrin 
Published: May 2022

Aims: In this study, the antibiofilm activity of citric acid on P. fluorescens isolated from raw milk samples was studied.
Background: Due to the resistance it gives to Pseudomonas bacteria, the presence of biofilm has been mentioned in recent studies. Biofilm is defined as the irreversible mucoid layer that microorganisms form on any surface and milk biofilms, which are the cause of contamination in milk, are a major concern in the dairy industry.
Methods: In this study, antibiofilm activity of citric acid and chlorine was investigated in 16 Pseudomonas fluorescens strains isolated from raw milk samples. For this purpose, the prevention and removal of biofilm formation of P. fluorescens strains was determined comparatively after treatment with microtitration plates with chlorine or citric acid.
Results: It was found that after treatment of microplates with citric acid, biofilm formation in P. fluorescens isolates was prevented by 52% and eliminated by 71-78%. It was also found that after the microplates were treated with chlorine, biofilm formation was prevented by 48% and eliminated by 61%.
Conclusion: This study showed that it was observed that citric acid can be used as an antibiofilm against biofilms produced by P. fluorescens bacteria.

ObjectiveSystemic juvenile idiopathic arthritis (JIA) associated with lung disease (JIA‐LD) is a potentially life threating complication in children with systemic JIA. Although high‐resolution computed tomography (HRCT) is considered the gold standard imaging modality for evaluating interstitial lung disease (ILD), lung ultrasound (US) has shown utility for ILD screening in adults with connective tissue diseases at lower cost and without using ionizing radiation. The goals of this pilot study were to describe lung US features in children with known systemic JIA‐LD and to assess the feasibility of lung US in this population.MethodsChildren age <18 years with systemic JIA‐LD and healthy controls were enrolled. Lung US acquisition was performed at 14 lung positions. Demographic, clinical, and HRCT data were collected and reviewed. Feasibility was assessed through patient surveys. Lung US findings were qualitatively and semiquantitatively assessed and compared to HRCT findings.ResultsLung US was performed in 9 children with systemic JIA‐LD and 6 healthy controls and took 12 minutes on average to perform. Lung US findings in systemic JIA‐LD included focal to diffuse pleural irregularity, granularity, and thickening, with associated scattered or coalesced B‐lines, and subpleural consolidations. Lung US findings appeared to correspond to HRCT findings.ConclusionLung US in systemic JIA‐LD reveals highly conspicuous abnormalities in the pleura and subpleura that appear to correlate with peripheral lung findings on HRCT. Lung US is a feasible imaging tool in children even from an early age. This study suggests a potential role of lung US in systemic JIA‐LD screening, diagnosis, and/or prognostication.

AbstractTumor targeting and effective immunomodulation are of critical significance during tumor treatment by sonodynamic therapy (SDT). Herein, the probiotic engineering of the clinically approved sonosensitizer (hematoporphyrin monomethyl ether (HMME)) is reported onto the probiotic bacterium Bifidobacteria Longum (BiL) for sonosensitive bifidobacterium construction (HMME@BiL cells). Based on the hypoxic tropism feature of the strain, effective tumor‐targeted sonodynamic therapeutics can be achieved both in vitro and in vivo. To improve the immunological responses against tumor during sonodynamics, a recently‐developed stimulator of interferon genes immune agonist SR717 has been employed to improve the anti‐tumor immunity with prominent activities, eradicating both primary and metastatic tumors with high efficiency and satisfied biocompatibility. The present work provides a promising paradigm of microbiotic nanomedicine in a sophisticated sonoimmunotherapeutic strategy against malignant tumors.

ObjectiveTo examine rates of intravenous thrombolysis (IVT), mechanical thrombectomy (MT), door‐to‐needle (DTN) time, door‐to‐puncture (DTP) time, and functional outcome between patients with admission magnetic resonance imaging (MRI) versus computed tomography (CT).MethodsAn observational cohort study of consecutive patients using a target trial design within the nationwide Swiss‐Stroke‐Registry from January 2014 to August 2020 was carried out. Exclusion criteria included MRI contraindications, transferred patients, and unstable or frail patients. Multilevel mixed‐effects logistic regression with multiple imputation was used to calculate adjusted odds ratios with 95% confidence intervals for IVT, MT, DTN, DTP, and good functional outcome (mRS 0–2) at 90 days.ResultsOf the 11,049 patients included (mean [SD] age, 71 [15] years; 4,811 [44%] women; 69% ischemic stroke, 16% transient ischemic attack, 8% stroke mimics, 6% intracranial hemorrhage), 3,741 (34%) received MRI and 7,308 (66%) CT. Patients undergoing MRI had lower National Institutes of Health Stroke Scale (median [interquartile range] 2 [0–6] vs 4 [1–11]), and presented later after symptom onset (150 vs 123 min, p < 0.001). Admission MRI was associated with: lower adjusted odds of IVT (aOR 0.83, 0.73–0.96), but not with MT (aOR 1.11, 0.93–1.34); longer adjusted DTN (+22 min [13–30]), but not with longer DTP times; and higher adjusted odds of favorable outcome (aOR 1.54, 1.30–1.81).InterpretationWe found an association of MRI with lower rates of IVT and a significant delay in DTN, but not in DTP and rates of MT. Given the delays in workflow metrics, prospective trials are required to show that tissue‐based benefits of baseline MRI compensate for the temporal benefits of CT. ANN NEUROL 2022;92:184–194

Published: May 2022

AbstractMultimetallic nitride species, especially those containing biologically related iron or molybdenum, are fundamentally important to understand the nitrogen reduction process catalysed by FeMo‐nitrogenase. However, until now, there remains no report about the construction of structurally well‐defined FeMo heteronuclear nitrido complex and its reactivity toward ammonia formation. Herein, a novel thiolate‐bridged FeIIMoVI complex featuring a bent Fe−N≡Mo fragment is synthesized and structurally characterized, which can be easily protonated to form a μ‐imido complex. Subsequently, through the proton‐coupled electron transfer (PCET) process, this imido species can smoothly convert into the μ‐amido complex, which can further undergo reductive protonation to afford the FeMo complex containing an ammine ligand. Overall, we present the first well‐defined {Fe(μ‐S)2Mo} platform that can give a panoramic picture for the late stage (N3−→NH2−→NH2−→NH3) of biological nitrogen reduction by the heterometallic cooperativity.

AbstractNano‐ and micromaterials with anisotropic photoluminescence and photon transport have widespread application prospects in quantum optics, optoelectronics, and displays. But the nature of the polarization information of the out‐coupled light, with respect to that of the source luminescence, has never been explored in active optical‐waveguiding organic crystals. Herein, three different modes (selective, anisotropic, and consistent) of polarized‐photon out‐coupling are proposed and successfully implemented in a set of 2D organic microcrystals with highly linearly‐polarized luminescence. It is found that the polarization direction and degree of the luminescence out‐coupled through different waveguiding channels can either be essentially retained or distinctly changed with respect to those of the original luminescence, depending on the molecular arrangement and the orientation of transition dipole moments of the crystal. This work demonstrates the promising potential of 2D emissive microcrystals in multi‐channel polarized photon transport.

AbstractOrganic–inorganic hybrid perovskites (OIHPs) have gained tremendous interest for their rich functional properties. However, the coexistence of more than one of ferroelectricity, ferromagnetism and ferroelasticity has been rarely found in OIHPs. Herein, we report a two‐dimensional Cr2+‐based OIHP, [3,3‐difluorocyclobutylammonium]2CrCl4 ([DFCBA]2CrCl4), which shows both ferroelectricity and ferromagnetism. It undergoes a 4/mmmFm type ferroelectric phase transition at a temperature as high as 387 K and shows multiaxial ferroelectricity with a saturate polarization of 2.1 μC cm−2. It acts as a soft ferromagnet with a Curie temperature of 32.6 K. This work throws light on the exploration of OIHPs with the coexistence of ferroelectricity and ferromagnetism for applications in future multifunctional smart devices.
Synthesis of Twisted Anthracenes: Induction of Twist Chirality by the Planar Chiral [2.2]Paracyclophane

Published: May 2022

AbstractPlanar chiral [2.2]paracyclophane was employed as chiral scaffolds to twist an anthracene ring by tethering at its 1‐ and 8‐positions; thus, twist chirality was induced in the anthracene moiety. The chiroptical properties of the resulting molecule, including circular dichroism (CD) and circularly polarized luminescence (CPL), were found to be derived from the twist chirality. An analogous molecule bearing long alkyl chains was a viscous liquid at ambient temperature, and its liquid film exhibited good CD and CPL profiles. Theoretical studies are carried out to determine the origin of these properties in the ground and excited states, which reproduced well the experimental results.

Published: May 2022

AbstractBackgroundHomocysteine (Hcy) has been confirmed to be associated with depression, but its relationship with poststroke depression (PSD) remains controversial. So far, there is no meta‐analysis of the correlation between Hcy level in acute stroke and PSD.MethodsA systematic search of a sub‐database of studies reporting the level of Hcy in the acute phase of ischemic stroke and PSD as of November 2021 was performed. Data extraction was performed strictly according to the inclusion and exclusion criteria. All data were analyzed using STATA 11.0. The standardized root mean square difference (SMD) and 95% confidence interval (CI) were used to compare continuous variables.ResultsA total of 11 studies were included in this study, including 2789 participants. The results of this meta‐analysis showed that admission the levels of Hcy were significantly higher in PSD survivors, compared to non‐PSD survivors (SMD = 0.37, 95%CI = 0.07–0.66, P ＜ .001). Subgroup analysis showed that survivors with PSD diagnosed more than 3 months after stroke had significantly different the levels of from non‐PSD survivors (6 months: SMD = 0.61, 95%CI = 0.40–0.82, 9 months: SMD = 1.00, 95%CI = 0.59–1.41).ConclusionThe level of Hcy in the acute phase of ischemic stroke is a risk factor for PSD.

Published: May 2022

AbstractCylindrical, cm‐sized monolithic Al2O3 xerogels with hierarchical meso‐/macropore system were prepared by sol‐gel synthesis. The influence of both solvent exchange and drying on monolith stability and the resulting pore system was studied following mass and volume of the monolith as well as by porosimetry and electron microscopy. Crack‐free drying of the monoliths requires a proper management of drying stress. This is achieved by adjusting the drying rate and solvent exchange procedure applied to the intermediate lyogels. Moreover, mainly through differences in capillary pressure, changing the pore fluid allows an adjustment of the mesopore width from 7.6 nm to 10.5 nm. Neither solvent exchange nor drying affect the macropores, the width of which stays at 1.5 μm. Finally, CO2 methanation over Ni‐impregnated Al2O3 monoliths reveals CO2 conversion and CH4 selectivity comparable to an industrial Ni/Al2O3 benchmark catalyst.
Electron Transfer Kinetics in Ethaline/Water Mixtures: An Apparent Non‐Marcus Behavior in a Deep Eutectic Solvent
Authors: Zhen Fangchen , Hapiot Philippe 
Published: May 2022

AbstractEffects of water on the charge‐transfer (CT) kinetics in deep eutectics solvents (DES) have been investigated in ethaline (1 : 2 choline chloride+ethylene glycol), taken as a prototypical example of a hydrophilic DES. Standard heterogeneous CT rate constants ks were measured for two redox couples: 1,1’‐ferrocene‐dimethanol/1,1’‐ferrocenium‐dimethanol and ferro‐/ferricyanide on a glassy carbon electrode in ethaline as function of the water amount in the DES. Contrarily to the behavior reported in classical solvents and in apparent contradiction with the Marcus Theory, ks values show very little or no variation with the amount of water in the DES or the changes of viscosities or diffusion coefficients that are observed. This unexpected phenomenon is discussed as function of the known physical‐chemistry parameters of ethaline.
Computational Prediction of the Adsorption Equilibrium for Ionic Surfactants at the Electrified Oil/Water Interface

Published: May 2022

AbstractIn a previous study (Somekawa et al., Langmuir 2019, 35, 11345–11350) a non‐Bornian solvation model was successfully applied to computational prediction of the adsorption equilibrium for nonionic surfactants at the oil (O)/water (W) interface. In this study, the method was extended to the adsorption of “ionic” surfactants at the polarized O/W interface. In this extension, the electrostatic potential of an ionic surfactant in the electric double layer formed at the O/W interface was taken into account together with the chemical potential estimated using the non‐Bornian solvation model. The calculation results clearly showed that a cationic surfactant (hexadecyltrimethylammonium ion) was adsorbed at the nitrobenzene/W interface, when the interfacial potential was negative. This prediction was consistent with the previous experimental observation using electrocapillary measurements.
