description: In addressing the cosmological constant problem, we propose that the discrepancy between the theoretical and observed values can be ascribed to the inherent uncertainty in the spacetime metric. Mach's principle, which posits that mass shapes spacetime, intersects with quantum mechanics' description of a particle as a quantum cloud, rendering the precise location of a particle's mass unknowable. Consequently, understanding spacetime structure at the quantum level becomes elusive. This connection between quantum and spacetime uncertainty could hold the key to resolving the cosmological constant problem. Intriguingly, the length scale of spacetime uncertainty, aligns with the macroscopic quantum weirdness observed in recent experiments. The spacetime uncertainty can be quantified by the scale factor in the Friedmann-Lemaitre-Robertson-Walker (FLRW) universe.

description: An increase in the water level occurred in Lake Naivasha which lead to its merging with Lake Oloiden. This resulted to an estuarine environment. This occurrence may lead salinization of Lake Naivasha may have an impact in the fish distribution and diversity. The study was conducted monthly in the 7 study sites along a salinity gradient, for one year; salinity was measured using YSI Multiparameter meter and fish were caught using gill nets. Main aim of the study was to determine spatial diversity and distribution of fish along a salinity gradient in Lakes Naivasha and Oloiden. Oloiden ST1, Oloiden ST2 and the other sites were distinct; a slight increase in salinity was noted at Oloiden ST2 before a drop (Oloiden ST2: Oseria was 3.5:1). Lake Oloiden (310±65 ppm) had a higher salinity as compared to the Lake Naivasha (96±20 ppm). A total of 10 fish species were caught and they belonged to: Cichlidae, Centrarchidae, Cyprinidae and Clarridae. Oreochromis niloticus, Cyprinus carpio and Clarius gariepinus and contributed the largest percentages in the catch: 65.3, 16.8 and 12 respectively. Malewa had the highest fish diversity index (H'=0.46) while the lowest was in the Midlake (0.17). Species evenness was highest in Malewa and lowest in Korongo. The Crescent had the highest species richness (d=2.8) while Midlake's was the lowest (0.5). Diversity index and evenness were low while species richness was high. There was a variation in the diversity and distribution of fish along the salinity gradient and fish of commercial importance migrated to Lake Oloiden post its merging with Lake Naivasha. Fish species diversity and evenness were low while species richness was high. Further research on the fish species diversity along the salinity gradient is recommended due to changes that may occur in biotic and abiotic factors with respect to time.

description: With extensive variational simulations, dissipative quantum phase transitions in the sub-Ohmic spin-boson model are numerically studied in a dense limit of environmental modes. By employing a generalized trial wave function composed of coherent-state expansions, transition points and critical exponents are accurately determined for various spectral exponents, demonstrating excellent agreement with those obtained by other sophisticated numerical techniques. Besides, the quantum-to-classical correspondence is fully confirmed over the entire sub-Ohmic range, compared with theoretical predictions of the long-range Ising model. Mean-field and non-mean-field critical behaviors are found in the deep and shallow sub-Ohmic regimes, respectively, and distinct physical mechanisms of them are uncovered.

description: Die Thiol-Disulfid-Austauschreaktion ist eine nukleophile Substitution, die in einer großen Klasse von Proteinen stattfindet. Sie spielt eine wichtige Rolle für die dritt- und viertdimensionale Struktur von Proteinen und die Katalyse biologischer Reaktionen. Außerdem kann der Thiol-Disulfid-Austausch die Aktivität bestimmter Proteine regulieren. In dieser Arbeit werden die strukturellen und Umgebungsfaktoren, die diese Reaktion beeinflussen, diskutiert. Aufgrund ihrer Recheneffizienz hat sich die Density-Functional based Tight-binding (DFTB) Methode als beliebte und zuverlässige quantenmechanische Methode für Anwendungen in kondensierter Phase positioniert. Mit DFTB ist es möglich die freie Energiefläche komplexer Reaktionen zu erzeugen, da der Phasenraum usreichen abgetastet werden kann. Diese Einsparungen bei den Rechenkosten können jedoch auf Kosten einer geringeren Genauigkeit gehen. Beim Thiol-Disulfid-Austausch zum Beispiel weisen die Übergangszustände eine fehlerhate Struktur und Energie auf. Die Literaturrecherche zeigt, dass für eine korrekte Beschreibung dieser Reaktion sehr genaue ab initio Methoden verwendet werden müssen. Daher bestand die Motivation dieser Arbeit darin, die DFTB-Fehler mit einem maschinellen Lernansatz zu korrigieren. Um dies zu erreichen, haben wir ein neuronales Netzwerk vom Typ Behler-Parrinello verwendet, das die Energiewertdifferenzen zwischen der ab initio und DFTB Methode füreine gegebene Molekülstruktur erlernt. Die maschinell erlernte Energiekorrektur wurde dann in die DFTB+ Software implementiert. Mit diesem neuen Ansatz konnten wir hybride Quantum Mechanics/Molecular Mechanics (QM/MM)-Simulationen des Thiol-Disulfid-Austauschs mit Coupled Cluster und B3LYP-Genauigkeit mit einem Rechenaufwand durchführen, der mit DFTB vergleichbar ist. Dieser Korrekturalgorithmus ist auch in einer Pipeline mit grafischer Schnittstelle implementiert, die dem Benutzer hilft, Trainingsdaten zu generieren und zu arrangieren sowie das maschinelle Lernmodell in DFTB+ zu exportieren, um es in QM/MM-Simulationen weiter zu verwenden. Die Einführung dieser Pipeline soll die Anwendungsmöglichkeiten des Codes für neuronale Netze erweitern, indem das Wissen über Quantenmodellierung gegenüber einem Programmierhintergrund bevorzugt wird. Darüber hinaus stellen wir erste Arbeiten an einem maschinell erlernten Kraftfeld zur Beschreibung der Disulfid-Austauschreaktion unter Verwendung von Coupled Cluster-Referenzdaten vor.

description: Emulsions are mixtures of two immiscible liquids, commonly oil and water, that can be stabilized and modified by emulsifying agents that reduce the interfacial energy between the two phases by adsorbing at their boundary [1, 2]. These agents find a wide range of applications in various industries, such as cosmetics, food, and pharmaceuticals, due to their unique properties, such as stability and versatility [3, 4]. Understanding the stability and related properties of these substances, including interfacial phenomena, is critical to developing high-quality and stable dispersions. Molecular Dynamics (MD) simulations are a powerful tool for exploring complex chemical systems at the molecular level. MD allows for the analysis of properties across microscopic and macroscopic scales, providing insights into the underlying phenomena of interphases [3]. In this work, the interfacial phenomena of emulsions composed of Triacylglycerols and Phospholipids (PL) of cocoa bean fat (Theobroma cacao L.), such as POS, SOS, POP, and PC, PS, PE, PI, PA, and LPC, respectively, were studied using MD. The goal was to evaluate the effect of PLs on interfacial stability and physicochemical properties, such as density and interfacial tension (IFT). The simulations of the systems were carried out in GROMACS 2019.3, and the results showed interfacial tension values ranging from 1-10 mN/m, indicating a reduction of interfacial tension with respect to oil and water systems. Furthermore, density analysis indicated the distribution of the interfacial zones of each compound within the emulsion. RDF graphs indicated the presence of strong hydrogen bonding between the polar head groups of POPC and interfacial water, as evidenced by short distances and high peaks, which suggest that they are closely packed and abundant in the interface. However, further analysis is necessary to understand stability, such as correlating the RDF with stability evaluation such as HLB [5]. These preliminary results suggest that cocoa bean fat chemical compounds can be used to prepare emulsions under experimental conditions. To validate the theoretical model, experimental data obtained from analytical and standardized methods, such as HLB analysis, IFT, Emulsion Stability, Pendant Drop method, etc., were used for comparison. These analytical and standardized methods are essential for validating the theoretical model and ensuring that predictions and results are accurate and reliable.

description: Emulsions are a type of semi-stable mixture of two immiscible liquids that can be blended with the aid of an emulsifying agent, typically mixtures of phospholipids (PLs) or proteins. They are essential for altering interfacial properties in the emulsion [1]. These compounds help reduce the energy required to create a surface tension at the interface of both phases, thereby stabilizing the mixture and preventing coalescence [2]. In this growing industry, a bioeconomy process is underway that involves the use of natural resources to produce innovative products. Considering the increasing cacao industry in Colombia, it's necessary to study the components naturally produced in this plant.
For this reason, this study aims to investigate the emulsifying properties of phospholipids from cacao (Theobroma cacao L) and their relationship with interfacial phenomena in an emulsion, using computational tools such as molecular dynamics (MD) to explore these physicochemical properties. To study these processes, a 50 ns MD simulation was conducted using a lipid bilayer system composed of major triglycerides (POS, SOS, and POP) and cacao-derived PLs (PC, PI, PE, PA, and PG). The simulation used the NPT ensemble with conditions of 311 K and 1 bar, utilizing the supercomputer INKARI (UNSA, Peru).
The results obtained so far indicate a reduction in the interfacial tension (IFT), starting from an initial value of approximately 19 mN/m (water-oil system without a surfactant) to a final value of 3.03 mN/m, which is consistent with the literature [3]. Additionally, theoretically calculated HBL analyses and correlation with the RDF of polar groups of PLs indicate that the mixture of PLs (cacao lecithin) falls within the range of W/O emulsifiers, with a theoretical calculated value of 5.07. Furthermore, some analyses, such as RMSD, SASA, RDF, and Radius of Gyration, among others, demonstrated the stability of PLs at the oil-water interface throughout the simulation.

description: Diabetic Retinopathy (DR) is a significant cause of blindness globally, highlighting the urgent need for early detection and effective treatment. Recent advancements in Machine Learning (ML) techniques have shown promise in DR detection, but the availability of labeled data often limits their performance. This research proposes a novel Semi-Supervised Graph Learning SSGL algorithm tailored for DR detection, which capitalizes on the relationships between labelled and unlabeled data to enhance accuracy. The work begins by investigating data augmentation and preprocessing techniques to address the challenges of image quality and feature variations. Techniques such as image cropping, resizing, contrast adjustment, normalization, and data augmentation are explored to optimize feature extraction and improve the overall quality of retinal images. Moreover, apart from detection and diagnosis, this work delves into applying ML algorithms for predicting the risk of developing DR or the likelihood of disease progression. Personalized risk scores for individual patients are generated using comprehensive patient data encompassing demographic information, medical history, and retinal images. The proposed Semi-Supervised Graph learning algorithm is rigorously evaluated on two publicly available datasets and is benchmarked against existing methods. Results indicate significant improvements in classification accuracy, specificity, and sensitivity while demonstrating robustness against noise and outlie rs.Notably, the proposed algorithm addresses the challenge of imbalanced datasets, common in medical image analysis, further enhancing its practical applicability.

description: Background: The shortage of skilled surgical providers in Sub-Saharan Africa is reaching a crisis level.The Canadian Network for International Surgery has been delivering structured surgical skills courses in Ethiopia for 15 years. However, an assessment of met needs, and ongoing barriers to surgical care has never been done. Ethiopia has set out plans to expand surgical capacity at the district hospital levels through upgrading and building hospitals, and task shifting through a surgical health officer program. This study aimed to assess the met need for surgical infrastructure, providers, and educationin in North Gondar Zone, Ethiopia. Sub-objectives are to assess the perceived values of a structured surgical training courses, and to identify ongoing barriers to emergency surgery. Method: This mixed-method of study employed: semi-structured interviews to surgical providers, a review of operative records, an infrastructure needs assessment. The research also used questionnaires which was distributed to medical trainees to assess the met needs, and to identify barriers to care.A total of190 trainees participated in the survey. In addition, 12 participants were involved in the interview from 4 hospitals. I n addition, descriptive statistics were used to describe the study subjects and the surgical skill needs using tables and graphs. Result: Emergency surgery was only performed in Gondar University Hospital with a met need for a cesarean section of only 15%. There was a severe shortage of both hospitals, and care providers in the zone. Lack of consumable emergency equipment was cited as the greatest barrier to delivering emergency care at the district level. Conclusion: Shortage of providers, inadequate surgical infrastructure, and a severe lack of continuing skill improvement needs were observed.

description: In molecules like hydrogen, most chemical bonds are formed by sharing two electrons from each atom in the bonding molecular orbital (two-center-two-electron (2c2e) bonding). There are, however, different kinds of chemical bonding. The I3- molecule, for example, is noteworthy because three iodine atoms are linearly united by sharing four electrons (three-center-four-electron (3c4e) bonding). Some inorganic solids undergo phase transitions that result in the formation of "molecules" in their crystalline frameworks, which are often accompanied by dramatic changes in physical properties; the metal-to-insulator transition (MIT) in vanadium dioxide, for example, occurs with the formation of dimer molecules with 2c2e bonding. We repot the creation of a linear ruthenium trimer with 3c4e bonding in ruthenium monopnictide at its MIT. Charge transfer from polymerized phosphorous to ruthenium produces this unusual molecule, with all conduction electrons trapped by the bonding molecular orbital. Our results demonstrate that molecules are crucial even in solid crystals as they impact their electronic properties.

description: The disorder-free localization that occurred in the study of relaxation dynamics in far-from-equilibrium quantum systems has been widely explored. Here we investigate the interplay between the dipole-dipole interaction (DDI) and disorder in the hard-core polar bosons in a one-dimensional lattice. We find that the localized dynamics will eventually thermalize in the clean gas, but can be stabilized with the existence of a small disorder proportional to the inverse of DDI strength. From the effective dimer Hamiltonian, we show that the effective second-order hopping of quasiparticles between nearest-neighbor sites is suppressed by the disorder with strength similar to the effective hopping amplitude. The significant gap between the largest two eigenvalues of the entanglement spectrum indicates the dynamical confinement. We also find that the disorder related sample-to-sample fluctuation is suppressed by the DDI. Finally, we extend our research from the uncorrelated random disorder to the correlated quasiperiodic disorder and from the two-dimer model to the half-filling system, obtaining similar results.

description: A search for pulse signals in a area with declinations of $+52\degr <δ<+55\degr$ was carried out on the LPA LPI radio telescope. When processing ten months of observations recorded in six frequency channels with a channel width of 415 kHz and a total bandwidth of 2.5 MHz, 22 thousand events were found with a pronounced dispersion delay of signals over frequency channels, i.e. having signs of pulsar pulses. It turned out that the found pulses belong to four known pulsars and two new rotating radio transients (RRATs). An additional pulse search conducted in 32-channel data with a channel width of 78 kHz revealed 8 pulses for the transient J0249+52 and 7 pulses for the transient J0744+55. Periodic radiation of transients was not detected. The analysis of observations shows that the found RRATs are most likely pulsars with nullings, where the proportion of nulling is greater than 99.9\%.

Information Discovery

description: The rapid growth of cutting-edge technology in science and education served as a catalyst for the development of practical skills to support learning, teaching, and research. Open access issues require an understanding of specific concepts and the use of techniques, applications, procedures to optimise the scientific work. Digitisation opened major opportunities for research activity, imposed the use of common formats and standards for expressing data and knowledge. The topic of digital skills is linked to an assumed career route, to the principles of lifelong learning, to the integration of current issues of academic ethics, and to the laws governing open research. The presentation illustrated particular contexts and skills necessary for information discovery in an open access environment.

description: Two approaches are developed for the study of the bound states of a one-dimensional Dirac equation with the potential consisting of $N$ $δ$-function centers. One of these uses the Green's function method. This method is applicable to a finite number $N$ of $δ$-point centers, reducing the bound state problem to finding the energy eigenvalues from the determinant of a $2N\times2N$ matrix. The second approach starts with the matrix for a single delta-center that connects the two-sided boundary conditions for this center. This connection matrix is obtained from the squeezing limit of a piecewise constant approximation of the delta-function. Having then the connection matrices for each center, the transmission matrix for the whole system is obtained by multiplying the one-center connection matrices and the free transfer matrices between neighbor centers. An equation for bound state energies is derived in terms of the elements of the total transfer matrix. Within both the approaches, the transcendental equations for bound state energies are derived, the solutions to which depend on the strength of delta-centers and the distance between them, and this dependence is illustrated by numerical calculations. The bound state energies for the potentials composed of one, two, and three delta-centers ($N=1,\,2,\,3$) are computed explicitly. The principle of strength additivity is analyzed in the limits as the delta-centers merge at a single point or diverge to infinity.

description: Coastal and barrage waters are polluted by heavy metals to varying degrees causing potential risks to underwater life. The present study aims to detect the major and trace elements in cement and its components used for the construction of dams and barrages. Essential ingredients of barrage materials including Portland cement, clays, and sediments have been quantitatively analyzed. The compositional analysis was performed using calibration-free laser-induced breakdown spectroscopy (CF-LIBS) based on the intensities of the optical emission spectra. The analysis by laser ablation time of flight mass spectroscopy (LA-TOF-MS) was performed based on the ionic mass spectra of the constituent elements. The optical emission spectra of the samples revealed the presence of calcium, potassium, iron, and magnesium as major elements, aluminum, titanium, silicon, sodium, and lithium as minor elements, while barium, manganese, and strontium were present at trace concentrations. Toxic and hazardous elements were present within the safe limits. The LA-TOF-MS results conform the LIBS values showing the reliability of these complementary techniques for the compositional analysis of materials.

description: Randomized Controlled Trials (RCTs) are widely considered to provide the most convincing evidence on the impacts of education interventions. It can, however, be very difficult to conduct RCTs that have high external validity. Whatever the site selection mechanism — even if it is truly random — a nontrivial share of sites will decline to participate, and the remaining sites will typically be meaningfully less representative of the target population. This project seeks to improve the field’s capacity to conduct evaluations that produce findings which are externally valid or generalizable to broader policy settings by examining and developing methods to improve the external validity of randomized trials of education interventions when sites are not required to participate. Using simulations and the Common Core of Data (CCD), the research will test established methods for site selection: stratified random site selection and methods for systematically selecting sites to match the target population. The researchers will also develop and test methods for selecting replacement sites modeled after methods used in survey research. The research team will simulate simple purposive selection rules based on factors that researchers often consider when selecting sites. The team will then estimate external validity bias by comparing the impacts from the sites simulated to participate in the study to the impacts from all sites in the population. This will provide data with which to conduct a formal test for the presence of external validity bias and to estimate the mean squared error for each site selection method. The research reported here is supported by the Institute of Education Sciences, U.S. Department of Education, through Grant R305D190020 to Westat.

description: Variable (wavelength) selection is critical in the multivariate calibration of spectra that improves prediction performance and provides clearer interpretation. Most variable selection methods use Y information (chemical reference of interest) to evaluating the importance of variables. In this work, a novel variable selection is proposed that requires no reference information. Replicate spectra of a sample under various acquisition conditions were used with an index to evaluate the importance of variables. The results show that the proposed method achieves better results than the original partial least squares model with a few available calibration samples. When a large number of calibration samples are available, this method provided comparable results to the state-of-the-art variable selection methods while reduced the risk of model over-fitting.

description: In this paper, we review the main contributions developed by the authors to solve problems involving contact between bodies with a roughness covering several orders of magnitude. A periodic self-equilibrated formulation is introduced to avoid any border problem. Furthermore, when focusing on the steady-state rolling or sliding contact mechanics between viscoelastic materials, we develop a mathematical formulation, parametrically dependent on the rolling/sliding speed, which employs the same computational techniques introduced for elastic rough contacts. In particular, in both cases, we adopt an ad hoc discretization technique enabling us to reach the full convergence.

description: An ultra-sensitive electrochemical immunosensor for detecting carcinoembryonic antigen was prepared. Graphene oxide-gold was used as the substrate modifier of the sandwich immunosensor. The high conductivity of graphene oxide effectively enhanced the electron transfer rate. The large specific surface area of graphene and the biocompatibility of gold nanoparticles increased the number of primary antibodies. The bovine serum albumin coated silver – platinum composite was used as a secondary antibody tag to prepare signal probes. The excellent biocompatibility of bovine serum albumin increased the number of secondary antibody connections. Silver nanoparticles increased the speed of electron transfer, and platinum further enhanced electrochemical sensing capabilities by catalyzing hydrogen peroxide. The immunosensor showed good performance for detecting carcinoembryonic antigen. Under the optimal conditions, the dynamic response range for carcinoembryonic antigen was from 0.005 ng·mL−1 to 100 ng·mL−1 with a detection limit of 0.76 pg·mL−1. The immunosensor also shown high selectivity, suitable stability, and good reproducibility, which provides new capabilities for clinical carcinoembryonic antigen detection.

description: This paper investigates an improved empirical model predicting the propagation characteristics of coplanar waveguides (CPW) at G band based on a conventional analytical CPW model. A comparison with another quasi-analytic CPW model and fullwave em simulations is presented. The comparison results demonstrate that the improved CPW model shows excellent agreement with measurements on different substrate materials up to 220 GHz. This means that, for the first time, a comprehensive and efficient CPW description at higher frequency ranges up to G band is available. This improved CPW model can be applied and used during the design cycle of hybrid integrated circuits (ICs), monolithic microwave integrated circuits (MMICs) and printed circuits board (PCBs). Moreover, the enhanced accuracy of the improved CPW model can help to reduce uncertainties in on-wafer CPW-based measurements.
