Energy vulnerability is a critical concern for achieving energy security and meeting the SDGs. However, the role of economic complexity, which represents a country's production and export diversification, in energy vulnerability has been largely neglected in the literature. This study fills this gap by examining the impact of economic complexity on energy vulnerability for 69 developing countries over the period 2000-2019. For this purpose, MMQR and various instrumental variable (IV) estimation techniques (IV-Quantile, 2SLS, Lewbel, and Kiviet) were used. In addition, ESG indicators were included in the model as instrumental variables to address potential endogeneity issues between economic complexity and energy vulnerability. In doing so, the ESG indicators are also included in the model as instrumental variables to control for the endogeneity of economic complexity. Empirical findings show that economic complexity is associated with lower energy vulnerability across all quantiles. These results reveal that countries with diversified economic structures (higher economic complexity) may be more resilient to energy shocks. Therefore, developing countries should focus on structural reforms and improve their ESG performances to reduce energy vulnerability. In terms of control variables, financial development, digitalization, and human capital are associated with lower energy vulnerability, whereas increases in natural resource revenues are sometimes associated with lower vulnerability levels. This finding suggests that, in the context of energy vulnerability, the predictions of the resource curse theory may not be observed in every case.

Isik, Cem; Ongan, Serdar; Kuziboev, Bekhzod; Imamoglu, Ilyas Kays; Amin, Azka
This study investigates the impact of corporate social responsibility (CSR) on energy security (ENSEC) for 34 developed countries. It offers a new institutional perspective by linking CSR to ENSEC within the framework of sustainable development. MMQR, PLFC, and DID methods are used for this analysis. The MMQR results indicate that CSR enhances ENSEC across all percentiles (10%-90%) in both aggregate and disaggregated analyses, across the social, environmental, and governance dimensions. Moreover, the PLFC model's findings reveal that CSR promotes ENSEC in aggregate, regardless of income level. However, in the disaggregated estimates from the PLFC model, the social dimension of CSR has no effect on ENSEC, whereas the environmental and governance dimensions continue to have a positive effect on ENSEC. As for the impact of China's energy investment, only China's fossil energy investment ensures ENSEC. These findings provide important policy insights by empirically validating the role of CSR in addressing long-term energy risks.

İncele - MakaleAçık Erişim2026Scopus SJRQ2Network comparison methods detect temporal reorganization of psychophysiological integration invisible to conventional univariate analysis: Proof-of-concept using lunar-phase-timed measurements in elite athletes

Field studies using conventional univariate methods fail to detect physiological rhythms (melatonin, cortisol, sleep architecture) that are consistently documented under laboratory-controlled conditions, suggesting that temporal factors operate on systemic organization rather than isolated metrics. Network analysis quantifies conditional dependencies among variables simultaneously, enabling the detection of organizational changes independent of mean-level shifts. As an exploratory proof-of-concept, this study examines whether network comparison methods detect temporal reorganization of psychophysiological integration invisible to conventional repeated-measures analysis in elite athletes; no confirmatory causal inference is drawn. Twelve elite male athletes completed psychophysiological assessments (mood states, subjective well-being, neurocognitive performance, postural control, intermittent endurance) at three lunar phases (New Moon, First Quarter, Full Moon) in a counterbalanced design. Conventional repeated-measures ANOVA detected no temporal effects on isolated variables (all F < 2.87, p > 0.05, eta(2)p < 0.21). Network comparison revealed marked organizational differences: New Moon versus Full Moon networks exhibited distinct architecture (M = 0.31, padj = 0.008) and connectivity (S = 8.42, padj = 0.029). Centrality systematically redistributed from capacity and well-being constructs (New Moon: vigour z = 1.82) to recovery markers (Full Moon: stress z = 2.13). Twelve connections differed significantly, including enhanced stress-confusion coupling (Delta r = +0.39, p = 0.003). This proof-of-concept demonstrates that temporal measurements can exhibit systemic reorganization despite stable component means, resolving apparent contradictions between laboratory-detected physiological rhythms and field-based null findings. Temporal control measurements and multi-cycle replication are required to definitively attribute observed reorganization to lunar periodicity rather than generic temporal variation.

Mollamahmutoglu, Murat; Yilmaz, Yuksel
This article investigates the penetrability of microfine cement suspensions prepared with Rheocem 900 with and without superplasticizer additive into various graded fine-to-medium sands into which chemical grout permeation is only possible. Initially, the basic rheological properties such as viscosity, setting time, and stability of microfine cement suspensions are studied. In addition, penetration performance of the suspensions into various graded fine to medium sand specimens under different grouting pressures is examined. Finally, the strength and permeability characteristics of various graded fine-to-medium sand specimens permeated with microfine cement suspensions are studied. It is found that a superplasticizer additive greatly increases the grouting performance of microfine cement and reduces the grouting pressure. Moreover, it is seen that the unconfined compressive strengths of sand specimens permeated with a cement grout without additive are slightly less than those of sand specimens permeated with cement grout and superplasticizer additive. Further-more, permeability tests on specimens permeated with cement grouts with or without a superplasticizer reveals that all specimens are impermeable (k<1 10 7 m=s).

Tabakcioglu, Mehmet Baris; Kara, Ali
This article proposes an improved slope uniform theory of diffraction model for fast and more accurate field prediction for multiple wedge diffractions in the transition zone. The proposed method is based on the slope uniform theory of diffraction and the Fresnel zone concept, called the slope uniform theory of diffraction with convex hull. The article also provides simulation results for the comparison of the uniform theory of diffraction based algorithms with respect to the computation time and accuracy.

The first total synthesis of (4E,6E)-1,7-bis(3,4-dihydroxyphenyl)-hepta-4, 6-dien-3-one and an alternative synthesis of (4E,6E)-1,7-bis(4-hydroxyphenyl)- hepta-4,6-dien-3-one, two natural diarylheptanoids, mainly based on Claisen-Schmidt condensation were described. The crucial steps of the syntheses were the condensation of OH-protected 4-aryl-2-butanones with OH-protected 3-aryl-acrylaldehydes by the in situ enamination and then deprotection of OH groups to give the corresponding natural diarylheptanoids.
