description: Observables 'are observed' whereas beables just 'are'. This gives beables more scope in the cosmological and quantum domains. Both observables and beables are entities that form 'brackets' with 'the constraints' that are 'equal to' zero. We explain how depending on circumstances, these could be, e.g., Poisson, Dirac, commutator, histories, Schouten-Nijenhuis, double or Nambu brackets, first-class, gauge, linear or effective constraints, and strong, weak or weak-effective equalities. The Dirac-Bergmann distinction in notions of gauge leads to further notions of observables or beables, and is tied to a number of diffeomorphism-specific subtleties. Thus we cover a wide range of notions of observables or beables that occur in classical and quantum gravitational theories: Dirac, Kuchař, effective, Bergmann, histories, multisymplectic, master, Nambu and bi-. Indeed this review covers a representatively wide range of such theories: general relativity, loop quantum gravity, histories theory, supergravity and M-theory.

description: Typical Hamiltonian liquids display exponential "Lyapunov instability", also called "sensitive dependence on initial conditions". Although Hamilton's equations are thoroughly time-reversible, the forward and backward Lyapunov instabilities can differ, qualitatively. In numerical work, the expected forward/backward pairing of Lyapunov exponents is also occasionally violated. To illustrate, we consider many-body inelastic collisions in two space dimensions. Two mirror-image colliding crystallites can either bounce, or not, giving rise to a single liquid drop, or to several smaller droplets, depending upon the initial kinetic energy and the interparticle forces. The difference between the forward and backward evolutionary instabilities of these problems can be correlated with dissipation and with the Second Law of Thermodynamics. Accordingly, these asymmetric stabilities of Hamilton's equations can provide an "Arrow of Time". We illustrate these facts for two small crystallites colliding so as to make a warm liquid. We use a specially-symmetrized form of Levesque and Verlet's bit-reversible Leapfrog integrator. We analyze trajectories over millions of collisions with several equally-spaced time reversals.

description: Let $W$ denote a matrix $A_2$ weight. In this paper, we implement a scalar argument using the square function to deduce square-function type results for vector-valued functions in $L^2(\mathbb{R},\mathbb{C}^d)$. These results are then used to study the boundedness of the Hilbert transform and Haar multipliers on $L^2(\mathbb{R},\mathbb{C}^d)$. Our proof shortens the original argument by Treil and Volberg and improves the dependence on the $A_2$ characteristic. In particular, we prove that the Hilbert transform and Haar multipliers map $L^2(\mathbb{R},W,\mathbb{C}^d)$ to itself with dependence on on the $A_2$ characteristic at most $[W]_{A_2}^{\frac{3}{2}} \log [W]_{A_2}$.

description: We present a sample of 27 GRBs with detailed Swift light curves supplemented by late time Chandra observations. To answer the missing jet-break problem in general, we develop a numerical simulation based model which can be directly fit to the data using Monte Carlo methods. Our numerical model takes into account all the factors that can shape a jet-break: (i) lateral expansion (ii) edge effects and (iii) off-axis effects. Our results provide improved fits to the light curves and constraints on physical parameters. More importantly, our results suggest that off-axis effects are important and must be included in interpretations of GRB jet breaks.

description: Due to the increased popularity of herbomineral preparations in the healthcare sector, a new proprietary herbomineral formulation was formulated consisting of ashwagandha root extract and three minerals viz. zinc chloride, magnesium gluconate, and sodium selenate. The objective of the study was to evaluate the in vitro effect of Biofield Energy Healing (The Trivedi Effect®) on the test formulation using murine splenocyte cells. The herbomineral formulation was divided into two parts; one defined as the control, while the other part was treated with the Biofield Energy Healing Treatment performed from a remote distance by twenty renowned Biofield Energy Healers (The Trivedi Effect®) and defined as the Biofield Treated formulation. The splenocyte cells were exposed to test formulations at concentration from 0.00001053 to 10.53 µg/mL and were analyzed after 48 hours for cell viability using MTT assay. The expression of the cytokines (TNF-α, IFN-γ, IL-1β, and MIP-1α) was determined using ELISA assay. The cell viability data showed that all the tested concentration ranges were found to be safe with percentage cell viability at more than 80%. Further, TNF-α expression was significantly inhibited in the Biofield Treated test formulation group with respect to the vehicle control, while at 0.001053 and 0.1053 µg/mL, the expression was suppressed by 1.70% and 8.16%, respectively in the Biofield Treated test formulation compared to the untreated formulation. However, a significant immunosuppression was reported in IFN-γ expression at 0.00001053, 0.0001053, 0.01053, 0.1053, and 1.053 µg/mL by 12.63%, 2.31%, 8.31%, 9.15%, and 7.86%, respectively in the Biofield Treated test formulation compared with the untreated test formulation. The MIP-1α expression was inhibited by 8.31%, 21.53%, and 8.70% at 0.0001053, 0.01053, and 0.1053 µg/mL, respectively in the Biofield Treated formulation compared with the untreated test formulation. However, IL-1β expression was significantly suppressed by 19.72% at concentration 0.00001053 µg/mL in the Biofield Treated test formulation compared with the untreated test formulation. Thus, the down-regulation of tested cytokines and chemokines in the Biofield Energy Healing test formulation might be applicable for controlling acute and chronic inflammation in many clinical diseases. Overall, the results demonstrated that The Trivedi Effect®- Biofield Energy Healing (TEBEH) has the capacity to potentiate the immunomodulatory activity of the test formulation, which can be useful against autoimmune disorders. Biofield Treated Test formulation may also be useful in anti-aging, anti-inflammatory, stress management and in preventing immune-mediated tissue damage in organ transplants by improving overall health and quality of life.

description: Herbomineral formulations have increased in recognition and popularity due to their high safety and better therapeutic action. A new proprietary herbomineral formulation was formulated with a mixture of the herbal root extract of ashwagandha and three minerals viz. zinc, magnesium, and selenium. The aim of the study was to evaluate the immunomodulatory potential of Biofield Energy Healing (The Trivedi Effect®) on the test formulation when applied to splenocyte cells isolated from the Biofield Treated mice. The test formulation was divided into two parts. One part was denoted as the control without any Biofield Energy Treatment. The other part was defined as the Biofield Energy Treated sample, which received the Biofield Energy Healing Treatment remotely by seven renowned Biofield Energy Healers. A wide concentration range (0.00001053 to 10.53 µg/mL) of the test formulation was used to determine non-cytotoxic concentrations using MTT assay. Further, the expression of pro-inflammatory cytokines (TNF-α, MIP-1α, and IL-1β) was determined by ELISA method. The test formulation was evaluated and found to be safe up to 1.053 µg/mL with a percentage cell viability range of 73% to 97% using MTT assay. The Biofield Treated formulation improved the cell viability up to 6.61% compared with the untreated test formulation. TNF-α expression was significantly inhibited by 16.72% at 0.1053 µg/mL compared with the untreated test formulation, however expression was significantly altered by 53.67% and 25.62% at 0.01053 and 1.053 µg/mL, respectively compared to the untreated test formulation. TNF-α expression was also suppressed in the Biofield Treated test formulation at 0.001053 and 0.1053 µg/mL by 4.0% and 8.56%, respectively as compared with the vehicle control. MIP-1α suppression was reported in the Biofield Treated test formulation at 0.00001053 to 1.053 µg/mL by 8.43%, 22.02%, 21.92%, 20.54%, 5.40%, and 19.82%, respectively compared with the vehicle control. However, the Biofield Treated formulation further exhibited substantial suppression of MIP-1α at 0.0001053, 0.001053, 0.01053, and 0.1053 µg/mL by 13.50%, 7.38%, 36.83% (p≤0.001), and 2.53%, respectively compared with the untreated test formulation. In addition, significant inhibition of IL-1β secretion was reported in the Biofield Treated formulation at 0.0001053, 0.001053, 0.01053, and 0.01053 µg/mL by 32.40%, 14.99%, 60.42%, and 15.15%, respectively compared with the untreated test formulation. The Biofield Energy Healing Treatment significantly potentiated the immunosuppressive effect of the test formulation in Biofield Treated mouse splenocytes, which can be used for autoimmune and inflammatory diseases, stress management and anti-aging by improving overall health.

The formulation was divided into two parts; one was the control without any Biofield Energy Treatment, while the other part was defined as the Biofield Energy Treated sample, which received Biofield Energy Healing Treatment remotely by seven renowned Biofield Energy Healers. The test formulation was evaluated to find the expression of pro-inflammatory cytokines such as TNF-α, MIP-1α, and IL-1β along with non-cytotoxic concentrations by MTT assay. The splenocytes were given the Biofield Energy Treated and untreated sample at concentrations range (0.00001053 to 10.53 µg/mL) for 48 hours and was reported with safe concentration up to 1.053 µg/mL with percentage viability range from 76.7% to 109.2% in both samples. Biofield Energy Healing significantly enhanced the cell viability as compared with the untreated formulation. The expression of TNF-α was significantly inhibited in the Biofield Treated formulation at 0.01053, 0.1053, and 1.053 µg/mL by 1.77%, 1.93%, and 3.55%, respectively compared with the untreated formulation. The rest of the tested concentrations of the Biofield Treated formulation showed an increase in TNF-α expression at 0.00001053, 0.0001053, and 0.001053 µg/mL by 7.26%, 8.50%, and 8.50%, respectively compared to the vehicle control group. Similarly, the MIP-1α expression was inhibited by the Biofield Energy Treated formulation and showed immunosuppression activity at 0.01053 µg/mL by 18.47% (p≤0.001) compared to the untreated formulation. MIP-1α expression was reported as 628.94 ± 13.0 pg/mL in the untreated formulation, while it decreased to 512.74 ± 1.9 pg/mL in the Biofield Treated formulation at 0.01053 µg/mL. In addition, the IL-1β secretion was also significantly inhibited by the Biofield Treated formulation at concentrations 0.001053, 0.01053, 0.1053, and 1.053 µg/mL by 72.02%, 50.16%, 30.68%, and 22.11%, respectively as compared with the untreated formulation. Overall, The Trivedi Effect® significantly down-regulated the pro-inflammatory cytokines and potentiated the immunosuppressive effect of the treated formulation, which can be better utilized in organ transplants, anti-aging, stress management, autoimmune disorders, and inflammatory disorders, etc. to modulate the immune system by improving overall health.

description: This study investigates the reciprocal relationship between students’ approaches to learning (SAL) and burnout among year-one university students. Prior research has linked SAL (i.e., deep, unreflective, organised studying) to burnout (i.e., exhaustion, cynicism, inadequacy), but few studies have explored the bidirectional relationship between SAL and burnout. To bridge this research gap, data from two cohorts of freshmen (Cohort 1, n = 261; Cohort 2, n = 216) were collected via the SAL scale (SALS) and school burnout inventory (SBI) at the beginning and end of their first year. Both cohorts exhibited bidirectionality between unreflective approach (UA) and cynicism, indicating that increased UA could lead to higher cynicism, and vice-versa. These findings underscore the importance of recognizing the interplay between UA and cynicism for interventions targeting UA reduction and emphasizes the need to consider the potential unintended consequences of heightening freshmen’s cynical atitudes towards studying when atempting to reduce UA.

Year: 2023

description: Nachverfolgbarkeitsverbindungen zwischen Architektur und Quelltext können das Wissen über ein System erweitern. Aufgrund des Erstellungsaufwands existieren in Softwareprojekten oft keine oder nur unvollständige Nachverfolgbarkeitsinformationen. Diese Arbeit untersucht einen Ansatz mit zwei Schritten, um automatisiert Nachverfolgbarkeitsverbindungen zwischen Architekturmodellelementen und Quelltext zu generieren. Damit die Erstellung von Nachverfolgbarkeitsverbindungen für verschiedene Programmiersprachen und Architektur-Metamodelle vereinheitlicht wird, werden im ersten Schritt aus den vorliegenden Artefakten Modelle erstellt. Der Quelltext wird dabei in ein von der konkreten Programmiersprache unabhängiges Modell überführt. Dafür wird ein Metamodell verwendet, das auf dem von der OMG spezifizierten KDM basiert. Für den zweiten Schritt werden auf den erstellten Modellen arbeitende Heuristiken und Aggregationen definiert. Diese werden genutzt, um die Nachverfolgbarkeitsverbindungen zu generieren. Die Heuristiken nutzen zum Beispiel Paket-, Pfad-, Namen- und Methoden-Informationen. Die Evaluation des Ansatzes nutzt einen dafür erstellten Goldstandard mit fünf Fallstudien. Es werden Nachverfolgbarkeitsverbindungen für PCM, UML, Java und Shell generiert. Für den Mikro-Durchschnitt des F1-Maßes wird ein Wert von 99,11 % erreicht. Fließt jede Komponente und Schnittstelle in gleichem Maße in den Wert ein, beträgt das F1-Maß 93,71 %. Insgesamt können mit dem Ansatz dieser Arbeit also sehr gute Ergebnisse erzielt werden. Für die TEAMMATES-Fallstudie wird mithilfe mehrerer Quelltextversionen der Einfluss der Konsistenz auf die Ergebnisse untersucht. Der Mikro-Durchschnitt des F1-Maßes ist für die konsistentere Version um 6,05 Prozentpunkte höher. Die Konsistenz kann also die Qualität der Ergebnisse beeinflussen.

description: Time domain astronomy is an active research area now, which requires frequent observations of the whole sky to capture celestial objects with variations. In optical band, several telescopes in different locations could form a distributed telescope array to capture images of celestial objects continuously. However, there are millions of celestial objects to observe each night and we only have limited telescopes. Besides, the observation capacity of these telescopes would be affected by different effects, such as: the sky background or the seeing condition. It would be necessary to develop an algorithm to optimize the observation strategy of telescope arrays according to scientific requirements. In this paper, we propose a novel framework which includes a digital simulation environment and a deep reinforcement learning algorithm to optimize observation strategy of telescope arrays. Our framework could obtain effective observation strategies given predefined observation requirements and observation environment information. To test the performance of our algorithm, we simulate a scenario, which uses distributed telescope arrays to observe space debris. Results show that our algorithm could obtain better results both in discovery and tracking of space debris. The framework proposed in this paper could be an effective strategy optimization framework for future distributed telescope arrays, such as the Sitian project.

description: Kibble-Zurek mechanism (KZM) uses critical scaling to predict density of topological defects and other excitations created in second order phase transitions. We point out that simply inserting asymptotic critical exponents deduced from the immediate vicinity of the critical point to obtain KZM predictions can lead to results that are inconsistent with a more careful KZM-like analysis based on causality -- on the comparison of the relaxation time of the order parameter with the time "distance" from the critical point. As a result, scaling of quench-generated excitations with quench rates can exhibit behavior that is locally (i.e., in the neighborhood of any given quench rate) well approximated by the power law, but with exponents that depend on that rate, and that are quite different from the naive prediction based on the critical exponents relevant for asymptotically long quench times. Kosterlitz-Thouless scaling (that governs e.g. Mott insulator to superfluid transition in the Bose-Hubbard model in one dimension) is investigated as an example of this phenomenon.

description: Quantum polarization is investigated by means of a trajectory picture based on the Bohmian formulation of quantum mechanics. Relevant examples of classical-like two-mode field states are thus examined, namely Glauber and SU(2) coherent states. Although these states are often regarded as classical, the analysis here shows that the corresponding electric-field polarization trajectories display topologies very different from those expected from classical electrodynamics. Rather than incompatibility with the usual classical model, this result demonstrates the dynamical richness of quantum motions, determined by local variations of the system quantum phase in the corresponding (polarization) configuration space, absent in classical-like models. These variations can be related to the evolution in time of the phase, but also to its dependence on configurational coordinates, which is the crucial factor to generate motion in the case of stationary states like those here considered. In this regard, for completeness these results are compared those obtained from nonclassical N00N states.

We show how the ratio of 3- to 2-jets cross sections is affected by the presence of new physics and argue that it can be used to place a model-independent bound on new particles carrying QCD color charge. The current data potentially constrains such states to be heavier than a few hundred GeVs.

Harnessing QD-PUFs for Secure Authentication via Fuzzy Fingerprint Generation
Creators: name: Longmate, Kieran
Publisher: name: Lancaster University
Year: 2023

description: The field of security technology is an eternal race. For every step forwards that is made in producing technology to help secure something it is not long behind it that those who seek to attack it make one also. Cryptography is one key example, even as encryption algorithms get more advanced so too do the computers that can be used to brute force them. Anti-counterfeiting is another. For each new complex watermark or hologram to prove authenticity there shortly follows better production techniques that aid in replicating them. There is a solution to this within the concept of Quantum Dot Physically Unclonable Functions (QD-PUFs). Underpinned by the laws of quantum physics rather than mathematically hard problems they are, as their name suggests, impossible to replicate. Providing an extremely appealing solution to security concerns where authentication and identification are required. There are several matters however that prevent QD-PUFs from being used in a much more wide spread manner. The aim of this thesis is therefore to address these in order to move QD-PUFs closer to being widely available. The foremost of these issues is a way to digitise the output of QD-PUFs. This forms the bulk of this thesis in detailing, analysing and discussing the fingerprinting algorithms designed to perform this task. As well as this the stability of the QD-PUFs, how to hide the information within fingerprints and the influence of varying incident wavelengths are covered. All to provide a comprehensive discussion on QD-PUFs and their fingerprints.

description: Employee engagement is considered as one of the most powerful drivers of a company’s competitive advantage and high performance. Employee engagement involves creating prospects for employees to attach with their managers, colleagues and organizations. This study sought to assess the effects of HRM practices on employee engagement in Commercial Bank of Ethiopia. The HRM practices covered were performance appraisal, training and development, reward and compensation and communication. The study adopted a explanatory research design, covering a sample of 335 respondents drawn from a target population of 2050 employees of CBE. The data collected through a self-administered questionnaire was analyzed using descriptive and inferential statistics. Regarding HR practices or drivers of Employee Engagement, the average level of satisfaction for Communication is M=3.86, training and development M=3.66, Reward and compensation M=3.83 and performance appraisal M=3.74.The mean value for vigor M=5.57, dedication M=5.53, absorption M=5.5 and the overall mean of engagement was M=5.54. Correlation tests revealed a moderate positive correlation between reward and compensation with coefficient of 0.437. Performance appraisal, communication and training and development were weak positive correlation with coefficients of 0.277, 0.280 and 0.259 respectively at a 0.01 significance level

description: Supplement to Zhu et al., 2023, Temperature dependence of spring carbon uptake in northern high latitudes during the past four decades, in final submission to Global Change Biology.Abstract: In the northern high-latitudes, warmer spring temperatures generally lead to earlier leaf onsets, higher vegetation production and enhanced spring carbon uptake. Yet, whether this positive linkage has diminished under climate change remains debated. Here we used atmospheric CO2 measurements at Barrow (Alaska) during 1979-2020 to investigate the strength of temperature dependence of spring carbon uptake reflected by two indicators, spring zero-crossing date (SZC) and CO2 drawdown (SCC). We found a fall-and-rise in the interannual correlation of temperature with SZC and SCC (RSZC-T and RSCC-T), showing a recent reversal of the previously reported weakening trend of RSZC-T and RSCC-T. We used a terrestrial biosphere model coupled with an atmospheric transport model to reproduce this fall-and-rise phenomenon, and conducted factorial simulations to explore its potential causes. We found that a strong-weak-strong spatial synchrony of spring temperature anomalies per se has contributed to the fall-and-rise trend in RSZC-T and RSCC-T, despite an overall unbroken temperature control on net ecosystem CO2 fluxes at local scale. Our results provide an alternative explanation for the apparent drop of RSZC-T and RSCC-T during the late 1990s and 2000s, and suggest a continued positive linkage between spring carbon uptake and temperature during the past four decades. We thus caution the interpretation of apparent climate sensitivities of carbon cycle retrieved from spatially-aggregated signals.File descriptions:These data are the simulated 3-hourly CO2 concentrations at the location of Barrow station by the ORCHIDEE terrestrial biosphere model coupled with the LMDz6A atmospheric transport model. Six factorial experiments (named CTRL, fixFlux, fixWind, T1, T2, T3) were conducted to reproduce the observations and to test the mechanisms underlying the changing temperature dependence of spring CO2 drawdown. Detailed descriptions of the simulations can be found in the linked manuscript.

Different well-tested stellar model atmosphere simulations from different groups are widely applied to undertake this task. This paper provides a comparison of different model atmosphere families to allow a better estimate of systematic errors on host-star stellar parameter introduced by the use of one specific model atmosphere family only. We present a comparison of the ATLAS9, MARCS, Phoenix and Drift-Phoenix model atmosphere families including the M-dwarf parameter space (T$_{\rm eff}=2500$K$\,...\,$4000K, log(g)=3.0$\,...\,$5.0, [M/H]=$-2.5\,...\,0.5$). We examine the differences in the (T$_{\rm gas}$, p$_{\rm gas}$)-structures, in synthetic photometric fluxes and in colour indices. Model atmospheres results for higher log(g) deviate considerably less between different models families than those for lower log(g) for all T$_{\rm eff}=2500$K$\,...\,$4000K examined. We compiled the broad-band synthetic photometric fluxes for all available model atmospheres (incl. M-dwarfs and brown dwarfs) for the UKIRT WFCAM ZYJHK, 2MASS JHKs and Johnson UBVRI filters, and calculated related colour indices. Synthetic colours in the IR wavelengths diverge by no more than 0.15 dex amongst all model families. For all spectral bands considered, model discrepancies in colour diminish for higher T$_{\rm eff}$ atmosphere simulations. We notice differences in synthetic colours between all model families and observed example data (incl. Kepler 42 and GJ1214).

description: We study the non-uniqueness of factorizations of non zero-divisors into atoms (irreducibles) in noncommutative rings. To do so, we extend concepts from the commutative theory of non-unique factorizations to a noncommutative setting. Several notions of factorizations as well as distances between them are introduced. In addition, arithmetical invariants characterizing the non-uniqueness of factorizations such as the catenary degree, the $ω$-invariant, and the tame degree, are extended from commutative to noncommutative settings. We introduce the concept of a cancellative semigroup being permutably factorial, and characterize this property by means of corresponding catenary and tame degrees. Also, we give necessary and sufficient conditions for there to be a weak transfer homomorphism from a cancellative semigroup to its reduced abelianization. Applying the abstract machinery we develop, we determine various catenary degrees for classical maximal orders in central simple algebras over global fields by using a natural transfer homomorphism to a monoid of zero-sum sequences over a ray class group. We also determine catenary degrees and the permutable tame degree for the semigroup of non zero-divisors of the ring of $n \times n$ upper triangular matrices over a commutative domain using a weak transfer homomorphism to a commutative semigroup.

description: Ettore Majorana (1906-1938) disappeared while traveling by ship from Palermo to Naples in 1938. His fate has never been fully resolved and several articles have been written that explore the mystery itself. His demise intrigues us still today because of his seminal work, published the previous year, that established symmetric solutions to the Dirac equation that describe a fermionic particle that is its own anti-particle. This work has long had a significant impact in neutrino physics, where this fundamental question regarding the particle remains unanswered. But the formalism he developed has found many uses as there are now a number of candidate spin-1/2 neutral particles that may be truly neutral with no quantum number to distinguish them from their anti-particles. If such particles exist, they will influence many areas of nuclear and particle physics. Most notably the process of neutrinoless double beta decay can only exist if neutrinos are massive Majorana particles. Hence, many efforts to search for this process are underway. Majorana's influence doesn't stop with particle physics, however, even though that was his original consideration. The equations he derived also arise in solid state physics where they describe electronic states in materials with superconducting order. Of special interest here is the class of solutions of the Majorana equation in one and two spatial dimensions at exactly zero energy. These Majorana zero modes are endowed with some remarkable physical properties that may lead to advances in quantum computing and, in fact, there is evidence that they have been experimentally observed. This review first summarizes the basics of Majorana's theory and its implications. It then provides an overview of the rich experimental programs trying to find a fermion that is its own anti-particle in nuclear, particle, and solid state physics.

description: Area specific investigation of impacts derived from liming acid soils and the consequent effects on plant nutrient bioavailability and soil physicochemical properties is important. This work aimed at investigating dynamics of nutrient bioavailability and changes in soil physicochemical properties under liming acid soils in the west Wallaga zone of western Ethiopian high rainfall regions. Lime requirements were calculated for all soil samples using the acid saturation procedure. Then, important physicochemical properties of the soils and bioavailability of nutrients were determined following standard procedures. The highest changes observed as a result of liming were 36.59 to 37.19 cmol Kg−1 for CEC, 0.97% to 0.47% for SOC, 1.76 to 1.40 g cm−3 for bulk density, 30.31 to 37.21% for porosity, 30.25 to 34.55 µS cm−1 for EC, 2.56 to 0.26 cmol Kg−1 for EA, and 0.08 to 0.02% for TN. This is attributed to the relatively higher CEC of clayey soils. It was observed that liming conditions, CEC, EC, EA, SOM, TN, and AP have significant (p < 0.001) correlations amongst themselves and with some other soil physicochemical properties such as porosity, bulk density, and C/N ratio. Bioavailability of P, N, S, Ca, K, and Mg were significantly positively (p < 0.01) enhanced by liming. This is due to improved mineralization of organic compounds, solubilization of some K, Ca, and Mg compounds, and input of Ca and Mg through liming. More research may be necessary to create a further understanding of the long-term effects of liming acidic soils on innate sources of nutrients and biological properties.

description: This paper provides the first study of foreign investors’ trading in a sizeable European emerging stock market, using a combination of daily and monthly complete data collected at the destination. It also introduces the structural conditional correlation (SCC) methodology to identify the contemporaneous interaction between foreign flows and returns. We show that global emerging market returns are an additional driver of foreign flows after controlling for global developed market returns. Foreigners do negative (positive)-feedback-trade with respect to local returns at the monthly (daily) frequency. SCC methodology shows that the standard assumption in the literature that flows cause returns but not vice versa is not justified even at the daily frequency, making price impact estimates reported in previous literature questionable.

description: Perhaps no other symptom induces such fear and loathing as chronic pain. Perhaps it is the symptom that brings more patients into our practices than any other but also it is the symptom most likely to make us feel at first helpless as healers [1]. Complexity of patients with chronic pain, need for multidisciplinary approach, lack of alternative treatment options, opioid crisis, growing elderly population, and tremendous impact on the economy are the reasons behind the need to discover new biomarkers for chronic pain. New biomarkers would give scientists new options to tackle this problem from a different perspective. There is a significant number of research that analyzed proteins involved in pain. In our research, we gather proteins that are involved in chronic pain, used Bio profiling to build a network of protein-protein interactions in chronic widespread pain and discover new proteins for this condition. The information that we discovered can be used to facilitate clinical trials and the search for new drug targets.

description: The importance of community-based watershed management for rural development is well acknowledged, yet its comprehensive nature remains underappreciated. This study examines the perceptions of stakeholders and their level of coordination in implementing the watershed approach and its impact on food security. Data was collected from 63 professionals with diverse roles across organizations and 337 farmers from three micro watersheds in Qarsa Woreda, East Hararghe Zone, using surveys and interviews. Results showed varying views: 36% of professionals and 12.6% of farmers see it as a holistic rural development strategy, while 9% of professionals and 36.5% of farmers view it mainly as soil and water conservation. Chi-square tests revealed significant differences in professional perspectives based on organizational role and experience (p-values of 0.05 and 0.01), but farmers’ views were consistent across watersheds. The study also highlighted a lack of effective collaboration among stakeholders, both vertically and horizontally, in supporting local watershed management initiatives. To maximize the benefits of watershed management for food security, it is crucial to improve stakeholder understanding, enhance institutional coordination, and strengthen accountability mechanisms. Addressing these areas through better educational programs and collaborative efforts can support sustainable rural development and improve food security for communities and ecosystems.

description: Currently, there is a rapidly growing interest in modern clean energy generation in Ethiopia as a means to ensure economic and environmental sustainability. However, there is still a gap in empirical research addressing how investment in modern clean energy determines the development of a green economy in Ethiopia. This study examined the implication of renewable energy on green economy development in Ethiopia, specifically focusing on the relationship between modern clean energy consumption, economic growth, and environmental quality from 1990 to 2022. The study utilized annual time series data from the World Development Indicators (WDI), the Global Carbon Atlas (GCA), and the International Energy Agency (IEA). The auto regressive distributed lags (ARDL) econometric estimation technique was used to analyze the data. The findings revealed that the use of non-renewable energy, biomass, and modern clean energy were significant factors in explaining the variation in carbon dioxide emissions in Ethiopia. However, only contemporary clean energy demonstrated statistical significance in explaining long-term economic growth. The results suggest that the use of green energy sources, such as hydro, wind, and solar energy, can eventually lower carbon emissions while increasing output. It is recommended that Ethiopian authorities prioritize the promotion of renewable energy sources to prevent the economy from becoming more carbon-intensive in the future. This requires strong collaboration among policymakers, the government, and international cooperation organizations to boost investment in modern clean energy and ensure environmentally and economically sustainable development.
