description: An investigation was carried out to analyze the chemical profiles, antioxidant, anticholinesterase, and cytotoxic activities of essential oils derived from Stachys sivasica and Stachys cataonica. The chemical components of essential oils were identified using Gas chromatography-mass spectrometry (GC-MS). Anticholinesterase and antioxidant activities including DPPH, ABTS and FRAP, were performed spectrophotometrically with 96-well microplate reader. Also, the MTT assay was used to assess the cytotoxic activities of the samples against MCF-7, MRC-5, HeLa, and LNCaP cell lines. The essential oil from S. sivasica (EOS) contained phytol (22.68%) and 2-methyl-1-pentene (14.72%) as the dominant compounds, while the major constituents of the essential oil from S. cataonica (EOC) were 16-kaurene (9.93%) and α-bisabolol (9.64%). EOS demonstrated notable radical scavenging activity, with IC50 values of 0.381 mg/mL for DPPH radicals and 0.868 mg/mL for ABTS radicals. In contrast, EOC displayed higher activity in the reducing assay (FRAP), with an IC50 value of 0.612 mg/mL. Furthermore, both EOS and EOC showed greater inhibitory activity against acetylcholinesterase compared to butyrylcholinesterase (IC50: 82.348 μg/mL and 61.205 μg/mL, respectively). Finally, EOC exhibited noteworthy cytotoxic activity against all cell lines, while EOS demonstrated cytotoxic activity specifically against MCF-7 and MRC-5. These results indicate that the essential oils of both plants have the potential for further studies against Alzheimer’s disease and cancer.

description: This study aims to determine the chemical composition, in vitro antioxidant, and in vivo anti-inflammatory properties of Neolitsea pallens essential oil (NPEO). The essential oil was isolated using hydrodistillation in a Clevenger-type apparatus. The qualitative and quantitative composition of essential oil was determined by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-flame ionization detection (GC-FID), respectively. A total of 42 compounds were identified, accounting for 91.15% of the oil. The major components included β-caryophyllene (32.72%), germacrene D (9.11%), caryophyllene oxide (8.11%), β-sabinene (6.60%), and β-elemene (4.46%). NPEO demonstrated significant antioxidant activity in DPPH and ABTS+ free radical scavenging assays, with IC50 values of 49.05 μg/mL and 5.8 μg/ mL, respectively. In the in vivo anti-inflammatory tests, NPEO exhibited a maximum inhibition of 60.57% in the carrageenan-induced paw edema model and 50% in the xylene-induced ear edema model, both at a dose of 20 mg/kg. The presence of sesquiterpene hydrocarbons and oxygenated sesquiterpenes in NPEO may contribute to its enhanced antioxidant properties thereby reducing the inflammation in animal models.

description: Aluminum pigments were coated with Fe₂O₃ and CuO by solution‐based thermal decomposition of the urea nitrate compounds hexakisureairon(III)nitrate and tetrakisureacopper(II)nitrate. The deposition process was optimized to obtain homogeneously coated aluminum pigments. The growth of the surface coatings was controlled by investigation with scanning electron microscopy, energy dispersive X‐ray spectroscopy and static light scattering as well as infrared, X‐ray diffraction and thermogravimetric analysis. The iron precursor showed an incomplete decomposition in solution, incorporating traces of urea molecules inside the coatings while the copper precursor showed complete dissociation accompanied by in situ formation of amine complexes. The amount of organic residues resulting from ligand fragments in the final oxide coatings could be reduced to 22 % for the iron oxide and 12 % for the copper oxide by further temperature treatment in solution (259 °C). Colorimetric investigations of the obtained pigments revealed an excellent hiding power, outperforming the pigments used in current state‐of‐the‐art formulations.

description: The strong coupling in the effective quark mass was usually taken as a constant in a quasiparticle model while it is, in fact, running with an energy scale. With a running coupling, however, the thermodynamic inconsistency problem appears in the conventional treatment. We show that the renormalization subtraction point should be taken as a function of the summation of the biquadratic chemical potentials if the quark's current masses vanish, in order to ensure full thermodynamic consistency. Taking the simplest form, we study the properties of up-down ($ud$) quark matter, and confirm that the revised quasiparticle model fulfills the quantitative criteria for thermodynamic consistency. Moreover, we find that the maximum mass of an $ud$ quark star can be larger than two times the solar mass, reaching up to $2.31M_{\odot}$, for reasonable model parameters. However, to further satisfy the upper limit of tidal deformability $\tildeΛ_{1.4}\leq 580$ observed in the event GW170817, the maximum mass of an $ud$ quark star can only be as large as $2.08M_{\odot}$, namely $M_{\text{max}}\lesssim2.08M_{\odot}$. In other words, our results indicate that the measured tidal deformability for event GW170817 places an upper bound on the maximum mass of $ud$ quark stars, but which does not rule out the possibility of the existence of quark stars composed of $ud$ quark matter, with a mass of about two times the solar mass.

description: Hypericum perforatum L. is a medicinally and commercially important plant with a long history of traditional use. It is used for conditions such as depression, wound healing, ulcers, and the common cold. The medicinal properties of H. perforatum are primarily attributed to its essential oil (EO). Various soil conditions, such as pH, soil texture (sand, silt, and clay content), nutrient content (potassium, magnesium, calcium, sodium, iron, copper, zinc, and manganese), and organic matter, can influence the composition and concentration of EO in plants. In this study, these conditions were investigated aiming to understand the influence of soil’s physical and chemical properties on the EOs extracted from H. perforatum collected from various localities. Dried aerial parts of H. perforatum from 20 different locations in Eskişehir, Turkey, were hydrodistilled using a Clevenger-type apparatus. The EO components were analyzed using GC-FID and GC-MS systems. Soil samples were collected from the same 20 local habitats and subjected to physical and chemical analyses. The results were then correlated with the main EO components. GC-MS results identified 119 compounds, representing 71-96.6% of the volatiles in all samples. The findings revealed that specific soil parameters, including Mg, Ca, dust, lime, clay, and pH, had a significant impact on the yield and chemical composition of H. perforatum EO, particularly affecting the levels of α-pinene, caryophyllene oxide, 1-dodecanol, and 1-tetradecanol. Further research is needed to fine-tune these soil parameters in conjunction with other ecological factors to maximize the qualitative and quantitative yield of EO from H. perforatum.

description: The essential oil isolated by hydro-distillation from Magnolia tiepii leaves was analyzed by GC-MS and assessed for antimicrobial and anticancer activities. Thirty-three components of the essential oil were identified, and the major components were β-pinene (40.8%), β-funebrene (12.0%), and trans-meta-mentha-2,8-diene (8.1%). The oil’s antimicrobial activity was assessed using IC50 values to determine its efficacy against six bacterial strains and one fungus strain. The IC50 values ranged from 2.30 mg/mL to 42 mg/mL, except for C. albicans, whose IC50 did not reach the highest concentration tested (>42 mg/mL). In addition, the anticancer activity of the M. tiepii essential oil was evaluated on KB, HepG2, MCF-7, and A549 cancer cell lines using the MTT method. These cell lines were treated with essential oil samples at concentrations ranging from 0.16 to 42 μg/mL. The M. tiepii essential oil exhibited high anticancer activity, with IC50 values ranging from 0.90 μg/mL to 2.07 ± 0.06 μg/mL across the four tested cell lines. These promising results underscore the potential of M. tiepii essential oil for cancer treatment, offering hope for future research and applications.

description: This work is the seventh study in a series dedicated to investigating degeneracies of simultaneous age, mass, extinction, and metallicity determinations of partially resolved or unresolved star clusters with Hubble Space Telescope broadband aperture photometry. In the sixth work (hereafter, Paper I), it was demonstrated that the adaptive aperture photometry, performed to avoid the majority of the projected foreground and background stars falling within the apertures, gives more consistent colour indices for star clusters. In this study, we aim to supplement the homogeneous multi-colour aperture photometry results published in Paper~I and provide a complete M31 Panchromatic Hubble Andromeda Treasury (PHAT) survey star cluster photometry catalogue for further analysis. Following Paper I, we used a two-aperture approach for photometry. The first aperture is the standard one used to measure total cluster fluxes. The second (smaller) aperture is introduced to avoid the bright foreground and background stars projecting onto the clusters. We selected the radii of smaller apertures to be larger than the half-light radii of the clusters. We present the second part of the star cluster aperture photometry catalogues for a sample of 1477 star clusters from the M31 PHAT survey not covered in Paper I. Compared to the M31 PHAT star cluster aperture photometry catalogue published by Johnson et al., adjustments were made to the cluster centre coordinates, aperture sizes, and sky background levels.

description: Single-particle traces of the diffusive motion of molecules, cells, or animals are by-now routinely measured, similar to stochastic records of stock prices or weather data. Deciphering the stochastic mechanism behind the recorded dynamics is vital in understanding the observed systems. Typically, the task is to decipher the exact type of diffusion and/or to determine system parameters. The tools used in this endeavor are currently revolutionized by modern machine-learning techniques. In this Perspective we provide an overview over recently introduced methods in machine-learning for diffusive time series, most notably, those successfully competing in the Anomalous-Diffusion-Challenge. As such methods are often criticized for their lack of interpretability, we focus on means to include uncertainty estimates and feature-based approaches, both improving interpretability and providing concrete insight into the learning process of the machine. We expand the discussion by examining predictions on different out-of-distribution data. We also comment on expected future developments.

description: Two new styryl lactone derivatives, goniothapic acids A (1) and B (2), and 18 known compounds, were isolated from the twig and leaf extracts of Goniothalamus tapis Miq. The structures of new compounds were characterised by spectroscopic methods and HRESITOFMS. Their absolute configuration was established by comparing the experimental and calculated ECD spectra. Eleven compounds were evaluated for their α-glucosidase inhibitory activity. Of these, (−)-goniothalamin (5) and oldhamactam (16) showed the best α-glucosidase inhibitory activity with IC50 values of 54.8 and 57.9 µM, respectively.

description: White dammar is an oleo-gum resin obtained from Vateria indica L. (Dipterocarpaceae) and is known to possess diverse biological activities. This study examines the chemical composition, antimicrobial, and antioxidant activities of essential oil extracted from white dammar. The chemical constituents of essential oil were identified by gas chromatography coupled with mass spectrometry (GC-MS) and flame ionization detection (FID). A total of 18 compounds constituting 97.15% of the oil were identified, which consist of β-caryophyllene (36.32%), α-humulene (14.31%), β-humulene (9.73%), caryophyllene oxide (8.28%), allo-aromadendrene (5.63%) and junenol (5.1%). The antimicrobial activity of the essential oil obtained was measured by means of disc diffusion assay, minimum inhibitory concentration (MIC), and minimum bactericidal/fungal concentrations (MBC/MFC). The highest antimicrobial activity was shown against Bacillus cereus (MIC/MBC = 31.2/62.5 μg/mL) and also Staphylococcus aureus (MIC/MBC = 62.5/125 μg/mL), whereas only a moderate level of activity was recorded against Salmonella typhi (MIC/MBC = 125/250 μg/mL), Vibrio cholerae, MRSA (MIC/MBC = 250/500 μg/mL) and Candida albicans (MIC/MFC = 125/250 μg/mL). Antioxidant activity was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric-reducing antioxidant power (FRAP) assays; IC50 value, of 29.42 μg/mL and FRAP value, of 166.5 ± 2.2 μmol Fe2+/g indicated that the essential oil exhibited adequate antioxidant activity. These results substantiate the possible medicinal application of white dammar as an antimicrobial and antioxidant agent.

description: The accelerated optical lattice has emerged as a valuable technique for the investigation of quantum transport physics and has found widespread application in quantum sensing, including atomic gravimeters and atomic gyroscopes. In our study, we focus on the adiabatic evolution of ultra-cold atoms within an accelerated optical lattice. Specifically, we derive a time bound that delimits the duration of atomic adiabatic evolution in the oscillating system under consideration. To experimentally substantiate the theoretical predictions, precise measurements to instantaneous band populations were conducted within a one-dimensional accelerated optical lattice, encompassing systematic variations in both lattice's depths and accelerations. The obtained experimental results demonstrate a quantitatively consistent correspondence with the anticipated theoretical expressions. Afterwards, the atomic velocity distributions are also measured to compare with the time bound. This research offers a quantitative framework for the selection of parameters that ensure atom trapped throughout the acceleration process. Moreover, it contributes an experimental criterion by which to assess the adequacy of adiabatic conditions in an oscillating system, thereby augmenting the current understanding of these systems from a theoretical perspective.

description: Medical image segmentation is a critical task that plays a vital role in diagnosis, treatment planning, and disease monitoring. Accurate segmentation of anatomical structures and abnormalities from medical images can aid in the early detection and treatment of various diseases. In this paper, we address the local feature deficiency of the Transformer model by carefully re-designing the self-attention map to produce accurate dense prediction in medical images. To this end, we first apply the wavelet transformation to decompose the input feature map into low-frequency (LF) and high-frequency (HF) subbands. The LF segment is associated with coarse-grained features while the HF components preserve fine-grained features such as texture and edge information. Next, we reformulate the self-attention operation using the efficient Transformer to perform both spatial and context attention on top of the frequency representation. Furthermore, to intensify the importance of the boundary information, we impose an additional attention map by creating a Gaussian pyramid on top of the HF components. Moreover, we propose a multi-scale context enhancement block within skip connections to adaptively model inter-scale dependencies to overcome the semantic gap among stages of the encoder and decoder modules. Throughout comprehensive experiments, we demonstrate the effectiveness of our strategy on multi-organ and skin lesion segmentation benchmarks. The implementation code will be available upon acceptance. \href{https://github.com/mindflow-institue/WaveFormer}{GitHub}.

description: We report the detection of large hydrocarbon cycles toward several cold dense clouds. We observed four sources (L1495B, Lupus-1A, L483, and L1527) in the Q band (31-50 GHz) using the Yebes 40m radiotelescope. Using the line stack technique, we find statistically significant evidence of benzonitrile (C$_6$H$_5$CN) in L1495B, Lupus-1A, and L483 at levels of 31.8$\,σ$, 15.0$\,σ$, and 17.2$\,σ$, respectively, while there is no hint of C$_6$H$_5$CN in the fourth source, L1527. The column densities derived are in the range (1.7-3.8)$\,\times\,10^{11}$ cm$^{-2}$, which is somewhat below the value derived toward the cold dense cloud TMC-1. When we simultaneously analyze all the benzonitrile abundances derived toward cold clouds in this study and in the literature, a clear trend emerges in that the higher the abundance of HC$_7$N, the more abundant C$_6$H$_5$CN is. This indicates that aromatic cycles are especially favored in those interstellar clouds where long carbon chains are abundant, which suggests that the chemical processes that are responsible for the formation of linear carbon chains are also behind the synthesis of aromatic rings. We also searched for cycles other than benzonitrile, and found evidence of indene (C$_9$H$_8$), cyclopentadiene (C$_5$H$_6$), and 1-cyano cyclopentadiene (1-C$_5$H$_5$CN) at levels of 9.3$\,σ$, 7.5$\,σ$, and 8.4$\,σ$, respectively, toward L1495B, which shows the strongest signal from C$_6$H$_5$CN. The relative abundances between the various cycles detected in L1495B are consistent -- within a factor of three -- with those previously found in TMC-1. It is therefore likely that not only C$_6$H$_5$CN but also other large aromatic cycles are abundant in clouds rich in carbon chains.

description: This study aimed to develop a mixed polymeric micelle formulation incorporating candesartan cilexetil (CAND) drug to enhance its oral bioavailability for the better treatment of hypertension. A Box–Behnken design was utilized to optimize the CAND-incorporated mixed polymeric micelles formulation (CAND-PFLC) consisting of Pluronics (P123 and F68) and lecithin (LC). The optimized CAND-PFLC micelles formulation was characterized for size, shape, zeta potential, polydispersity index (PDI), and entrapment efficiency (�). An in vitro release study, ex vivo permeability investigation, and an in vivo pharmacokinetic analysis were carried out to evaluate the performance of the formulation. The optimized CAND-PFLC micelles formulation demonstrated a spherical shape, a particle size of 44 ± 2.03 nm, a zeta potential of −7.07 ± 1.39 mV, a PDI of 0.326 ± 0.06, and an entrapment efficiency of 87 ± 3.12%. The formulation exhibited excellent compatibility, better stability, and a noncrystalline nature. An in vitro release study revealed a faster drug release of 7.98% at gastric pH in 2 hrs and 94.45% at intestinal pH within 24 hrs. The ex vivo investigation demonstrated a significantly enhanced permeability of CAND, with 94.86% in the micelle formulation compared to 9.03% of the pure drug. In vivo pharmacokinetic analysis showed a 4.11-fold increase in oral bioavailability of CAND compared to the marketed formulation. The CAND-PFLC mixed micelle formulation demonstrated improved performance compared to pure CAND, indicating its potential as a promising oral drug delivery system for the effective treatment of hypertension.

description: The primary objective of the research was to develop a cubosomal in situ gel encapsulated with Triamcinolone acetonide (TCA) in order to enhance its penetration through the blood-brain barrier (BBB) when administered via the intranasal route, thus enabling efficient and rapid action. Cubosomes were formulated by top-down approach using glyceryl monooleate (GMO), using pluronics127 (PF127) and polyvinyl alcohol (PVA) in varying proportions based on the Box-Behnken design. High resolution transmission electron microscopy (HR-TEM) analysis confirmed the morphology of the cubosomes. The in situ gel was formulated and optimized. Experiments involving ex vivo permeation and histopathology analyses were undertaken to evaluate drug permeation and tissue effects. The cubosomes exhibited a particle size (PS) of 197.9 nm, zeta potential (ZP) of −31.11 mV, and entrapment efficacy (EE) of 84.31%, with low deviation. Batch F4 (19% PF127) showed favorable results. In vitro and ex vivo permeation studies revealed drug release of 78.59% and 76.65%, respectively, after 8 h. Drug release followed the Hixson Crowell model of release kinetics. The histopathological examination revealed no signs of toxicity or adverse effects on the nasal mucosa of the sheep. The formulation exhibited short-term stability, maintaining its integrity and properties when stored at room temperature. The utilization of an intranasal cubosomal in situ gel encapsulated with TCA was anticipated to lower intracranial pressure and improve patient adherence by offering effective relief for individuals suffering from Brain edema. This efficacy is attributed to its rapid onset of action and its safe and well-tolerated dosage form.

description: There is an urgent and renewed interest in searching for effective and green pesticides to control mosquitoes. In this framework, the essential oil (EO) of the plant Deverra tortuosa was hydrodistilled, and analysed using gas chromatography-flame ionisation detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Dillapiole (40.2%), elemicin (8.1%), and myristicin (6.3%), phenylpropanoids, and sabinene (4.3%) a common monoterpene, were found to be the major EO components. The oil nanoemulsion (ONE) was developed adopting a green protocol, and then characterised. The EO, ONE, and terpenes, particularly the phenylpropanoids possessed considerable mosquitocidal bioactivity against the Asian tiger mosquito, Aedes albopictus. A percentage of 100% larval mortality was recorded when insects were treated with a concentration of 40 μL/mL of ONE after 24 hours of treatment, while double of this concentration from EO and dillapiole was required to achieve the same activity. The LC50’s against larvae ranged between 7.6 and 60.7 μL/mL. For adults, LC50’s ranged between 6.4 and 50.9 μL/L. At sub-lethal concentrations (0.625-5.0 μL/cm2), EO materials significantly repelled Ae. albopictus, where a concentration of 5.0 μL/cm2 of EO and ONE provided 100% protection for up to180 min. As a proposed mechanism of action, the EO materials considerably inhibited the activity of acetylcholinesterase (AChE). The test materials were safe for the mosquitofish, Gambusia affinis, a common larvivorous fish, and Eisenia fetida earthworm. Test materials were also safe for the white albino rat in an oral bioassay at a limit dosage of 3500 mg/kg b.wt. The findings support the use of the EO, nanoemulsion, and phenylpropanoids of D. tortuosa as environmentally benign natural mosquitocodes to control Ae. albopictus.

description: Large-scale synchrotron loops are recognized as the main source of diffuse radio-continuum emission in the Galaxy at intermediate and high Galactic latitudes. Their origin, however, remains rather unexplained. Using a combination of multi-frequency data in the radio band of total and polarized intensities, for the first time in this letter, we associate one arc -- hereafter, the Orion-Taurus ridge -- with the wall of the most prominent stellar-feedback blown shell in the Solar neighborhood, namely the Orion-Eridanus superbubble. We traced the Orion-Taurus ridge using 3D maps of interstellar dust extinction and column-density maps of molecular gas, $N_{\rm H_2}$. We found the Orion-Taurus ridge at a distance of 400\,pc, with a plane-of-the-sky extent of $180$\,pc. Its median $N_{\rm H_2}$ value is $(1.4^{+2.6}_{-0.6})\times 10^{21}$ cm$^{-2}$. Thanks to the broadband observations below 100 MHz of the Long Wavelength Array, we also computed the low-frequency spectral-index map of synchrotron emissivity, $β$, in the Orion-Taurus ridge. We found a flat distribution of $β$ with a median value of $-2.24^{+0.03}_{-0.02}$ that we interpreted in terms of depletion of low-energy ($<$ GeV) cosmic-ray electrons in recent supernova remnants ($10^5$ - $10^6$ yrs). Our results are consistent with plane-of-the-sky magnetic-field strengths in the Orion-Taurus ridge larger than a few tens of $μ$G ($> 30 - 40 \,μ$G). We report the first detection of diffuse synchrotron emission from cold-neutral, partly molecular, gas in the surroundings of the Orion-Eridanus superbubble. This observation opens a new perspective to study the multiphase and magnetized interstellar medium with the advent of future high-sensitivity radio facilities, such as the C-Band All-Sky Survey and the Square Kilometre Array.

description: This study applied various chromatographic methods to assess the chemical composition of five selected perennial and annual wheat seed varieties cultivated in Kazakhstan. Gas Chromatography (GC) analysis revealed distinct fatty acid profiles, with perennial, soft, and durum annual wheat seeds displaying varying levels of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA) (SFA: 10.538 − 19.676%, MUFA: 17.124 − 23.131%, PUFA: 58.649 − 66.938%). HPLC analysis uncovered significant differences in the content of total non-essential amino acids (TNEA) and essential amino acids (TEA). Among the analysed varieties, "Sova" had the highest TNEA content (4464.70 mg/g) with aspartic acid as the predominant amino acid (4146.35 mg/g), while "704" displayed the highest TEA content (579.95 mg/g) with tyrosine as the dominant amino acid (219.98 mg/g). These findings highlight the potential of Kazakh wheat varieties as rich sources of essential nutrients and hold promise for improving public health.

description: Product development projects usually contain many interrelated activities with complex information dependences, which induce activity rework, project delay and cost overrun. To reduce negative impacts, scheduling interrelated activities in an appropriate sequence is an important issue for project managers. This study develops a double-decomposition based parallel branch-and-prune algorithm, to determine the optimal activity sequence that minimizes the total feedback length (FLMP). This algorithm decomposes FLMP from two perspectives, which enables the use of all available computing resources to solve subproblems concurrently. In addition, we propose a result-compression strategy and a hash-address strategy to enhance this algorithm. Experimental results indicate that our algorithm can find the optimal sequence for FLMP up to 27 activities within 1 hour, and outperforms state of the art exact algorithms.

description: Abstract Sea surface temperature (SST) is critical to global climate change analysis and research. This study the quality-controlled in situ sea surface temperature (SST) and Visible and Infrared Scanning Radiometer (VIRR) SST data from Fengyun-3C (FY-3C) satellite processed by bias correction were used, and the Kalman filtering methods with oriented elliptic correlation scales were applied to construct SST fields. Firstly, the model of oriented elliptic correlation scale was established for SST analysis, then the observation observation errors from each type of SST data source were estimated using the optimal matched datasets, and the background field errors were calculated by using the model of oriented elliptic correlation scale. Finally, the blended SST analysis product using the Kalman filtering methods was obtained. Besides, in order to validate these SST results, the SST fields using the optimum interpolation (OI) method were chosen for comparions. The SST data quality analysis of 2016 revealed that the Kalman analysis has a better performance than those of the OI analysis with the root-mean-square errors (RMSEs) of 0.3911 and 0.3243 °C, respectively,which was more closer to the OISST product’s RMSE of 0.2897 °C. The results demonstrated that the Kalman filtering method with dynamic observation error and background error estimation was significantly superior to the OI method in SST analysis for FY-3C SST data.

description: The enzyme activity of catechol oxidase (CO) give rise to enzymatic browning, leading to undesirable changes in fruits and vegetables. The aim of this work is to investigate the inhibitory effect of five essential oils (EOs) on CO from date fruits (Phoenix dactylifera). Catechol oxidase has been purified from date fruit through three-phase partitioning (TPP). Essential oils were extracts from Artemisia herba-alba, Artemisia campestris, Thymus vulgaris, Origanum vulgare, and Salvia Rosmarinus, and were tested against CO. The composition of these five essential oils was then identified using GC-MS. Major constituents identified were camphor (20.91%) and davanone D (19%) for A. herba alba, capillene (47.79%) for A. compestris, thymol (33.75%) and linalool (30.44%) for T. vulgaris, carvacrol (68.60%) for O. vulgare, and camphor (33.89%) for S. Rosmarinus. The EO from A. campestris was the most potent inhibitor of enzyme (IC50 = 3.44±0.09 mg/mL) while the weakest effect was observed for EO of O. vulgare (IC50 = 10.24±0.29 mg/mL). Different mechanism of inhibition was obtained. Hence, a competitive inhibition for both EOs of A. herba-alba and T. vulgaris, uncompetitive behavior for A. campestris, noncompetitive mechanism for S. rosmarinus and O. vulgare were observed. The docking molecular of those major constituents was investigated using crystal structure of CO from Ipomoea batatas (1BT1). The best-docked compound was davanone D (-5.55 kcal/mol) while camphor show weaker docking scores (3.79 kcal/mol). Thus, the results from our work could be important and offer an approach of control enzymatic browning using essential oils.

description: Intuitive entropic interpretations of the thermoelectric effect in metals predict an isotropic Seebeck coefficient at high temperatures in the incoherent regime even in anisotropic metals since entropy is not directional. $\mathrm{Sr}_2\mathrm{Ru}\mathrm{O}_4$ is an enigmatic material known for a well characterised anisotropic normal state and unconventional superconductivity. Recent ab-initio transport calculations of $\mathrm{Sr}_2\mathrm{Ru}\mathrm{O}_4$ that include the effect of strong electronic correlations predicted an enhanced high-temperature anisotropy of the Seebeck coefficient at temperatures above 300 K, but experimental evidence is missing. From measurements on clean $\mathrm{Sr}_2\mathrm{Ru}\mathrm{O}_4$ single crystals along both crystallographic directions, we find that the Seebeck coefficient becomes increasingly isotropic upon heating towards room temperature as generally expected. Above 300 K, however, $S$ acquires a new anisotropy which rises up to the highest temperatures measured (750 K), in qualitative agreement with calculations. This is a challenge to entropic interpretations and highlights the lack of an intuitive framework to understand the anisotropy of thermopower at high temperatures.

description: This study introduces a cost-effective and automated methodology to swiftly and accurately gauge disaster-induced land cover changes, harnessing satellite imagery and machine learning. Using open-source platforms like Google Earth Engine, the approach streamlines training sample generation and assesses diverse machine learning algorithms on pre- and post-disaster Landsat images. The innovation lies in its semi-automatic training sample generation methodology, reducing time and manual effort for accurate land cover mapping and addressing the challenge of crafting training samples in disaster settings. The methodology was tested on the 2010 Chilean earthquake and tsunami, revealing a 45% increase in sediment cover and a 15% reduction in water cover, underlining vast landscape alterations. SVM stood out for its consistent accuracy. To validate the methodological robustness and broaden its applicability, we replicated the procedures using diverse land cover collection, including ESA WorldCover 10 m and Dynamic World. This comprehensive validation encompassed varied catastrophic events, extending the methodology’s relevance beyond its original scope. The consistent findings across different scenarios underscored the method’s robustness and underscored its potential for broader utilization. This streamlined, cost-effective approach suits multiple land cover products, setting the stage for constant Earth feature monitoring. In light of escalating natural disasters, the synergy of machine learning and geospatial technology spotlighted here offers promising avenues for improved disaster preparedness and response.
