description: A novel non-symmetric tripodal receptor (L) with benzimidazole and amide –NH functionalities has been synthesised and a comparative study for anion binding aptitude of those functionalities has been performed in solid state and solution phase. The protonated receptors in solid state tend to form a pseudo-cavity around the octahedral hexafluorosilicate anion whilst in second complex, binding of one sulphate and two bisulphates in unison by two protonated units arises. The benzimidazole –NHs are the strongest hydrogen bond donors in both the crystals controlling dominance over amide –NHs. The neutral receptor being selective towards fluoride anion induces a naked eye visible colorimetric change. The 1H NMR studies with the neutral and protonated form of the receptor suggest the strong involvement of amide –NH in anion binding in solution phase.

description: This study revisits antibiotic resistance as a source of evolutionary development in pathogenic bacteria. By taking a molecular phylogenetic approach to this inquiry, I seek to find homologous correlations in antimicrobial resistance gene families across a broad spectrum of bacteria, as to indentify the possible acquisition of those genes through divergent events in evolutionary context. In order to test this, I examine the various degrees of genetic similarity in two antimicrobial resistance genomic datasets, namely aadA1 & aadA2 aminoglycoside resistance genes, among bacteria that occur in a multitude of environments. Moreover, the results from phylogenetic analysis suggests that pathogenic antibiotic resistance for aadA1 & aadA2 aminoglycoside resistance genes may have been acquired through evolutionary events with a common ancestor of a soil-dwelling bacterium.

description: This study is mainly focused on the direct adsorption of low concentration gallium from the feed solution in pre-desilication soda-lime sintering process from coal fly ash. The adsorption kinetics, mechanism, and the influence of impurities, cyclic times, and eluant content are systematically researched. Results showed that the adsorption capacity was 2.89 mg/g resin with gallium concentration of 50 mg/L. The adsorption mechanism could be explained by the interaction between the oxygen atoms and nitrogen atoms of amidoxime group. Gallium was eluted efficiently by NaOH and Na2S mixed solution and the concentration could be reached to 2400 mg/L.

description: The growing digitalization of consumer behaviour in Nigeria has made online reviews a crucial factor influencing brand perception and customer engagement in service marketing. This study examines the extent to which online reviews impact consumer trust, loyalty, and interaction with brands across key service sectors such as banking, hospitality, healthcare, and e-commerce. Using a quantitative research approach, data was collected from 385 respondents through a structured questionnaire. Regression analysis revealed that online reviews significantly influence brand perception (R² = 0.551, p < 0.001) and customer engagement (R² = 0.483, p < 0.001). The findings indicate that positive online reviews enhance brand credibility and consumer trust, while negative reviews can deter potential customers unless effectively managed. However, challenges such as fake reviews and delayed brand responses hinder effective online reputation management. The study recommends that Nigerian service firms adopt proactive digital reputation strategies, including real-time engagement, authenticity assurance, and tailored response mechanisms, to enhance consumer confidence and brand loyalty.

description: A mixed ligand polymeric metal complex of Cd(II) has been prepared by reactions of Cd(NO3)2·4H2O with 1,3-diaminopropane (tn) and potassium salt of 1,1-dicyanoethylene-2,2-dithiolate and characterized on the basis of spectroscopy and single-crystal X-ray diffraction analysis. Single-crystal X-ray diffraction analysis reveals that the Cd(II) complex crystallizes in monoclinic space group P 21/n with distorted octahedral coordination geometry. The Cd(II) complex was screened in vitro against fungal pathogens such as Synchytrium endobioticum, Pyricularia oryzae, Helminthosporium oryzae, Candida albicans (ATCC10231) and Trichophyton mentagrophytes by the disc diffusion method. The biological testing data of the primary ligand K2i-MNT·H2O and [Cd(tn)(i-MNT)]n indicate that the complex exhibits fungistatic antifungal activity whereas K2i-MNT·H2O has no activity. The fungicidal properties of [Cd(tn)(i-MNT)]n showed that the cadmium complex was more bioactive than the parent ligand.

description: An oxo-bridged binuclear Cu(II) complex, [CuL2]2, has been synthesized and characterized by microanalysis, spectra (infrared and electronic) and X-ray diffraction crystallography. The theoretical properties of the complex were studied using semi-empirical PM3 method. The optimized geometries, dipole moment, thermodynamic parameters and vibrational frequencies were investigated. The crystal structure revealed that each Cu(II) was five-coordinate with a distorted square pyramidal geometry (τ = 0.324 and 0.307). The two units of the complex were bridged by the phenolic oxygens to give a binuclear Cu(II) complex with the average bridging angle and Cu…Cu distance being 98.49° and 3.413 Å, respectively. Theoretical studies revealed that the geometric parameters are in agreement with the experimental data. The compound was stable and has good non-linear optical properties.

H2L is a mono-negative bidentate ligand via hydrazone N and C–O− forming intermediate complexes between tetrahedral and square-planar geometries (“flattened” tetrahedron, D2d symmetry) for 1 and 2, as well as square-planar for Cu(II) complex 3. Natural bond orbital analysis revealed that the interaction of oxygen with metal ion is the main factor which determines the stability of 1–3 as the binding energy decreases with an increase in the M–O bond length. Time-dependent density functional theory calculations were carried out to understand the electronic transitions in related experimental observations. The reduction potential values of the nitro group are affected by the metal center. Ni(II) complex 2 displayed the highest activity among the tested complexes against Escherichia coli with a MIC50 value of 0.098 μmol mL−1 compared with 0.131 (1) and 0.117 μmol mL−1 (3).

description: Dynamic Link Prediction (DLP) addresses the prediction of future links in evolving networks. However, accurately portraying the performance of DLP algorithms poses challenges that might impede progress in the field. Importantly, common evaluation pipelines usually calculate ranking or binary classification metrics, where the scores of observed interactions (positives) are compared with those of randomly generated ones (negatives). However, a single metric is not sufficient to fully capture the differences between DLP algorithms, and is prone to overly optimistic performance evaluation. Instead, an in-depth evaluation should reflect performance variations across different nodes, edges, and time segments. In this work, we contribute tools to perform such a comprehensive evaluation. (1) We propose Birth-Death diagrams, a simple but powerful visualization technique that illustrates the effect of time-based train-test splitting on the difficulty of DLP on a given dataset. (2) We describe an exhaustive taxonomy of negative sampling methods that can be used at evaluation time. (3) We carry out an empirical study of the effect of the different negative sampling strategies. Our comparison between heuristics and state-of-the-art memory-based methods on various real-world datasets confirms a strong effect of using different negative sampling strategies on the test Area Under the Curve (AUC). Moreover, we conduct a visual exploration of the prediction, with additional insights on which different types of errors are prominent over time.

description: A series of non-enolizable β-diketonate-based copper(II) complexes with LCuCl2 [L = Knoevenagel condensates of curcumin (Salcimine) and methylacetoacetate (SalMaA)-based Schiff bases] chromospheres as functional models of chemotherapy drug cisplatin were investigated for their covalent interaction with herring sperm DNA. The synthesis and structural characterization of 1a and 1b have been reported in our previous article. However, their DNA interactions and cytotoxicity properties were not studied. These analyses have been carried out mainly through electrochemical techniques supplemented with spectral, relative viscosity, gel electrophoresis techniques, and AGS cancer cells using MTT assay. The cytotoxic activities of the ligand, curcumin-based copper complex, and cisplatin were tested against the AGS cancer cell line under similar experimental conditions showing that the complex exhibited cancer cell inhibitory rate closer to cisplatin even at low concentration. This was also seen in the docking of the Cu-complex onto a rich guanine B-DNA decamer, where a Cu–N3(guanine) interaction instead of Pt-N7 as cisplatin is detected. The obtained results in this study prove that these complexes could be a promising substitute for cisplatin as a new family of non-platinum-based anticancer metallo-drugs after in vivo tests on animal models.

description: The technology convergence integrating multiple devices into a single one is now a distinct trend in electronic industry. This trend can lead to a decrease in the use of rare and toxic heavy metals due to resource sharing, or an increase due to the application of new and auxiliary technology. This study investigates the effect of technology convergence for tablet PC on hazardous waste, resource depletion, and toxicity potentials from heavy metals in electronic devices, considering how many single devices (i.e., netbook computer, electronic dictionary, mp3 player, digital camera, cell phone, and vehicle GPS system) can be displaced by a tablet PC depending on users. The hazardous waste potential from heavy metals is examined with existing U.S. federal and California state regulations, and the resource depletion and toxicity potentials from heavy metals are evaluated based on life cycle impact assessments. The potentials of a specific tablet PC are compared to the total of those of displaced single products. Overall, the tablet PC has lower hazardous waste, resource depletion, and toxicity potentials from heavy metals. However, in case the tablet PC displaces only two or three single devices, it requires more gold, molybdenum, and vanadium. Therefore, technology convergence should take into account materials consumption and user behavior to develop more sustainable products.

description: In this study, we investigated the in vitro effect of 16-formyl-17-methoxy dehydroepiandrosterone derivatives on the activity of 5α-reductase type 2 (5α-R2) obtained from human prostate. The activity of different concentrations of these derivatives was determined for the conversion of labelled testosterone to dihydrotestosterone. The results indicated that an aliphatic ester moiety at the C-3 position of these derivatives increases their in vitro potency as inhibitors of 5α-R2 activity compared to finasteride®, which is considered to be a potent inhibitor of 5α-R2. In this case, the augmentation of the lipophilicity of these dehydroepiandrosterone derivatives increased their potency as inhibitors of 5α-R2. However, the presence of cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl or cycloheptyl rings as the cycloaliphatic ester moiety at C-3 of the formyl methoxy dehydroepiandrosterone scaffold did not inhibit the activity of this enzyme. This may be due to the presence of steric factors between the enzyme and the spatial structure of these derivatives.

description: The anticancer activity of ethanol extract isolated from Goji berry (EEGB) on T47D human breast cancer cell line has been reported. Cell viability and cell proliferation were examined with the use of BrdU, MTT and NR methods. Induction of apoptosis was assessed by propidium iodide and Hoechst 33342 staining. Expression of genes involved in cell proliferation, apoptosis, cell cycle control and regulation of transcription was estimated using Western blotting analysis. EEGB inhibited the proliferation of breast cancer cells in a time-, and dose-dependent manner. The study confirmed the lack of EEGB cytotoxic activity to normal human skin fibroblasts. Western blot analysis demonstrated an increase in pro-apoptotic and a decrease in anti-apoptotic proteins’ expression in cells treated with the extract. Anticancer activity and lack of toxicity against normal cells indicate a chemopreventive potential of Goji berries in breast cancer treatment.

description: This work presents the production technology of the strawberry cultivar ‘Idea’ by micropropagation. Meristems
of 0.5mm size were isolated in June from the stolons of examined strawberry sorts. They were raised on
Murashige and Skoog’s (Murashige and Skoog, 1962) medium in presence of 6-Benzylaminopurine (BAP),
Indole-3-butyric acid (IBA) and gibberellic acid (GA3). Fifty days later meristems were organized into a foliate
rosette. Multiplication was achieved on Murashige and Skoog’s substratum with BAP and IBA. The plants which
came to the size of about 10mm were shifted to the substratum for tree rooting. Tree rooting was achieved on
Murashige and Skoog’s substratum with IBA. Sixty days later the plants with strongly developed roots were
transplanted into the peaty briquettes. One month later the plants were transplanted into flowerpots and kept in
a greenhouse at a temperature of 10-150C.

description: The generalized extreme value distribution and its particular case, the Gumbel extreme value distribution, are widely applied for extreme value analysis. The Gumbel distribution has certain drawbacks because it is a non-heavy-tailed distribution and is characterized by constant skewness and kurtosis. The generalized extreme value distribution is frequently used in this context because it encompasses the three possible limiting distributions for a normalized maximum of infinite samples of independent and identically distributed observations. However, the generalized extreme value distribution might not be a suitable model when each observed maximum does not come from a large number of observations. Hence, other forms of generalizations of the Gumbel distribution might be preferable. Our goal is to collect in the present literature the distributions that contain the Gumbel distribution embedded in them and to identify those that have flexible skewness and kurtosis, are heavy-tailed and could be competitive with the generalized extreme value distribution. The generalizations of the Gumbel distribution are described and compared using an application to a wind speed data set and Monte Carlo simulations. We show that some distributions suffer from overparameterization and coincide with other generalized Gumbel distributions with a smaller number of parameters, that is, are non-identifiable. Our study suggests that the generalized extreme value distribution and a mixture of two extreme value distributions should be considered in practical applications.

description: A novel library based on quinolin-4-ylimidazoline core was designed to incorporate a general quinoline antimicrobial pharmacophore. A synthesis of the well-characterized library of 36 compounds was achieved using the Pd-catalyzed Buchwald–Hartwig-type imidazoline arylation chemistry developed earlier. Compounds were tested for biological activity and were found to possess no antimalarial activity. However, the library delivered two promising antitubercular leads, which are non-cytotoxic and can be further optimized with respect to antimycobacterial potency.

description: Representing the nodes of continuous-time temporal graphs in a low-dimensional latent space has wide-ranging applications, from prediction to visualization. Yet, analyzing continuous-time relational data with timestamped interactions introduces unique challenges due to its sparsity. Merely embedding nodes as trajectories in the latent space overlooks this sparsity, emphasizing the need to quantify uncertainty around the latent positions. In this paper, we propose TGNE (\textbf{T}emporal \textbf{G}aussian \textbf{N}etwork \textbf{E}mbedding), an innovative method that bridges two distinct strands of literature: the statistical analysis of networks via Latent Space Models (LSM)\cite{Hoff2002} and temporal graph machine learning. TGNE embeds nodes as piece-wise linear trajectories of Gaussian distributions in the latent space, capturing both structural information and uncertainty around the trajectories. We evaluate TGNE's effectiveness in reconstructing the original graph and modelling uncertainty. The results demonstrate that TGNE generates competitive time-varying embedding locations compared to common baselines for reconstructing unobserved edge interactions based on observed edges. Furthermore, the uncertainty estimates align with the time-varying degree distribution in the network, providing valuable insights into the temporal dynamics of the graph. To facilitate reproducibility, we provide an open-source implementation of TGNE at \url{https://github.com/aida-ugent/tgne}.

description: A series of non-enolizable β-diketonate based copper(II) complexes with LCuCl2 [L = Knoevenagel condensates of curcumin (Salcimine) and methylacetoacetate (SalMaA) based Schiff bases] chromospheres as functional models of chemotherapy drug cisplatin were investigated for their covalent interaction with herring sperm DNA (HS-DNA). The synthesis and structural characterization of 1a and 1b have been reported in our previous paper. However, their DNA interactions and cytotoxicity properties were not studied. These analyses have been carried out mainly through electrochemical techniques supplemented with spectral, relative viscosity, gel electrophoresis techniques and AGS cancer cells using MTT assay. The cytotoxic activities of the ligand, curcumin based copper complex and cisplatin were tested against the AGS cancer cell line under similar experimental conditions showing that the complex exhibited cancer cell inhibitory rate closer to cisplatin even at low concentration. This was also seen in the docking of the Cu-complex onto a rich guanine B-DNA decamer, where a Cu−N3(guanine) interaction instead of Pt-N7 as cisplatin is detected. The obtained results in this study prove that these complexes could be a promising substitute for cisplatin as a new family of non-platinum based anticancer metallo-drugs after in-vivo tests on animal models.

description: 1. Little is known about the activities and regulation of cytochrome P4503A (CYP3A) enzymes in porcine colon in response to specific feeding components. 2. We added hydrolyzable tannins to the diet of fattening boars and studied its effect on the expression of hepatic and intestinal CYP3A. 3. In total, 51 Landrace × Large White boars were assigned to the following treatment groups: control (without the addition of hydrolysable tannins), T1 (diet-containing 1% hydrolysable tannin extract), T2 (diet-containing 2% hydrolysable tannin extract) and T3 (diet-containing 3% hydrolysable tannin extract). CYP3A expression and activity were measured in microsomes prepared from liver and colon tissue. 4. CYP3A protein expression and activity were increased in the colon of pigs fed 2% and 3% tannins, while no changes were observed with lower tannin concentrations, or in the liver of any treatment groups. Also, it was demonstrated that colon mucosa possess CYP3A activity similar to that measured in the liver. 5. The present results provide the first evidence that tannin supplementation can modulate CYP3A in porcine colon mucosa in vivo. The physiological significance of this finding for the health status of the individual animal needs further investigation.

description: Remote sensing data provide a low-cost solution for large-scale monitoring of air pollution via the retrieval of aerosol optical depth (AOD), but is often limited by cloud contamination. Existing methods for AOD reconstruction rely on temporal information. However, for remote sensing data at high spatial resolution, multi-temporal observations are often unavailable. In this letter, we take advantage of deep representation learning from convolutional neural networks and propose Deep Feature Gaussian Processes (DFGP) for single-scene AOD reconstruction. By using deep learning, we transform the variables to a feature space with better explainable power. By using Gaussian processes, we explicitly consider the correlation between observed AOD and missing AOD in spatial and feature domains. Experiments on two AOD datasets with real-world cloud patterns showed that the proposed method outperformed deep CNN and random forest, achieving R$^2$ of 0.7431 on MODIS AOD and R$^2$ of 0.9211 on EMIT AOD, compared to deep CNN's R$^2$ of 0.6507 and R$^2$ of 0.8619. The proposed methods increased R$^2$ by over 0.35 compared to the popular random forest in AOD reconstruction. The data and code used in this study are available at \url{https://skrisliu.com/dfgp}.

description: A partir de finais do século XX com o colapso definitivo do antigo regime o mundo abriu-se a novas ideias e os grandes conflitos começaram a surgir. Num espaço de poucos anos duas guerras surgiram no seio da Europa e o mundo se transformou. Numa Itália devastada pela guerra, surgiram movimentos artísticos que entraram em confronto com o poder conservador instituído. Numa sociedade pobre e com grandes dificuldades em colmatar as mais elementares necessidades de sobrevivência, um movimento neorrealista viria a tomar corpo e a influenciar toda a produção cinematográfica subsequente e abriu caminho para o surgimento de outras gerações de autores e realizadores que mantiveram a ênfase no cinema de autor.
