This research paper aims to assess the sustainable competitiveness of Balkan countries. Sustainable competitiveness was measured based on the indicators in The Sustainable Competitiveness Report from 2022, published by Solability. According to this report, sustainable competitiveness is evaluated using six grouped criteria. In this paper, the competitiveness of the Balkan countries was assessed through the application of the multicriteria analysis methods Entropy and MARCOS (Measurement Alternatives and Ranking according to the Compromise Solution). The weight of each criterion was determined using the Entropy method. The results highlighted that the most significant criteria were Natural Capital and Resource Efficiency & Intensity, which carried the highest weight, whereas the Social Cohesion criterion was of lesser importance, represented by the lowest weight. Using the MARCOS method, the Balkan countries were ranked, with Greece securing the top position, closely followed by Albania, while North Macedonia exhibited the weakest performance. Sensitivity analysis further substantiated these findings. The outcomes of this study significantly contribute to the academic understanding of sustainable competitiveness and provide valuable practical insights for policymakers and stakeholders interested in advancing sustainable development efforts in the Balkan region.

We introduce the theory of high-order harmonic generation by aligned homonuclear diatomic cations using a strong-field approximation. The target cation is represented as a system which consists of two atomic (ionic) centres and one active electron, while the driving field is either a monochromatic or bichromatic field. For a linearly polarised driving field, we investigate the differences between the harmonic spectra obtained with a neutral molecule and the corresponding molecular cation. Due to the larger ionisation potential, the molecular cations can withstand much higher laser-field intensity than the corresponding neutral molecule before the saturation effects become significant. This allows one to produce high-order harmonics with energy in the water-window interval or beyond. Also, the harmonic spectrum provides information about the structure of the highest-occupied molecular orbital. In order to obtain elliptically polarised harmonics, we suggest that an orthogonally polarised two-colour field is employed as a driving field. In this case, we analyse the harmonic ellipticity as a function of the relative orientation of the cation in the laser field. We show that the regions with large harmonic ellipticity in the harmonic energy-orientation angle plane are the broadest for cations whose molecular orbital does not have a nodal plane. Finally, we show that the molecular cations exposed to an orthogonally polarised two-colour field represent an excellent setup for the production of elliptically polarised attosecond pulses with a duration shorter than 100 as.

Genetic factors are recognized as risk factors for statin-associated muscle symptoms (SAMS), which are the most common cause of statin intolerance. The aim of this study was to determine whether there is an association between polymorphisms 1236C > T, 2677G > T/A, and 3435C > T in the ABCB1 gene, encoding the efflux transporter of statins, and SAMS, as results on this topic are still controversial. A cross-sectional study was conducted on patients with or without SAMS using atorvastatin. The influence of non-genetic variables on SAMS was also evaluated. Our results show that patients with TT genotype in 1236C > T, 2677G > T/A, and 3435C > T polymorphisms had higher risk of developing SAMS, compared to wild type and heterozygous carriers together (OR 4.292 p  = 0.0093, OR 5.897 p  = 0.0023 and OR 3.547 p  = 0.0122, respectively). Furthermore, TTT/TTT diplotype was also associated with a higher risk of SAMS, OR 9.234 ( p  = 0.0028). Only family history of cardiovascular disease was found to be a risk factor for SAMS, in addition to the known non-genetic variables. We believe that ABCB1 genotyping has great potential to be incorporated into clinical practice to identify high-risk patients in a timely manner.

Human serum albumin (HSA) is one of the most important transporters for drugs in the systemic circulation. In this study, we investigated the interaction of rosuvastatin (ROS) and atorvastatin (ATO) with HSA. Binding of a drug molecule to HSA significantly affects the pharmacokinetics of the drug as it increases drug solubility in plasma, decreases toxicity and protects molecules from oxidation. This study was made using fluorescence spectroscopy and molecular modeling approach. Fluorescence spectra were recorded for two different statins brands at seven different concentrations. The results revealed that both statins (ROS and ATO) cause the fluorescence quenching of the HSA solution. ROS and ATO binds strongly to HSA with the binding constant (Kb) of 1.0246×106 and 0,9018×106, respectively. In addition, it was observed that high concentrations of ATO cause a shift of the emission maximum towards longer wavelengths (red-shift), which may be due to the unfolding of protein chains or denaturation. Furthermore, it was calculated that HSA possesses one binding site for ROS and ATO. Results from molecular docking showed that ROS has a higher affinity for Sudlow site I compared to Sudlow site II and the main binding forces are hydrogen bonds. ATO has nearly equal affinity for both binding sites on HSA, and the main binding forces are hydrophobic interactions.

The purpose of the present study is to propose an interval-valued type 2 fuzzy set (IT2FS)-based analytic hierarchy process (AHP) framework to unfold the critical challenging factors influencing the sustenance and growth of the Indian tea industry. The current work follows an expert opinion-based group decision-making approach. The challenging factors have been identified through a literature review and finalized after a pilot study based on the opinions of professionals, consumers, and experts. Finally, the critical challenging factors and sub-factors have been figured out through analysis of the responses of the experts. To offset the subjective bias, an IT2FS-based granular analysis has been carried out. The findings reveal that market diversification and productivity are the central issues. Additionally, it is important to give attention to improving the quality of the products, increasing the use of modern technology and organic farming, and developing a variety of products. The result shows a considerable level of consistency in the group decision-making (CR < 0.1) for all pairwise comparisons. The present work shall be of use to formulate appropriate strategies and policy decisions. It shows a robust application of IT2FS-AHP for complex decision-making in real life.

HOXB13 is a key lineage homeobox transcription factor that plays a critical role in the differentiation of the prostate gland. Several studies have suggested that HOXB13 alterations may be involved in prostate cancer development and progression. Despite its potential biological relevance, little is known about the expression of HOXB13 across the disease spectrum of prostate cancer. To this end, we validated a HOXB13 antibody using genetic controls and investigated HOXB13 protein expression in murine and human developing prostates, localized prostate cancers, and metastatic castration‐resistant prostate cancers. We observed that HOXB13 expression increases during later stages of murine prostate development. All localized prostate cancers showed HOXB13 protein expression. Interestingly, lower HOXB13 expression levels were observed in higher‐grade tumors, although no significant association between HOXB13 expression and recurrence or disease‐specific survival was found. In advanced metastatic prostate cancers, HOXB13 expression was retained in the majority of tumors. While we observed lower levels of HOXB13 protein and mRNA levels in tumors with evidence of lineage plasticity, 84% of androgen receptor‐negative castration‐resistant prostate cancers and neuroendocrine prostate cancers (NEPCs) retained detectable levels of HOXB13. Notably, the reduced expression observed in NEPCs was associated with a gain of HOXB13 gene body CpG methylation. In comparison to the commonly used prostate lineage marker NKX3.1, HOXB13 showed greater sensitivity in detecting advanced metastatic prostate cancers. Additionally, in a cohort of 837 patients, 383 with prostatic and 454 with non‐prostatic tumors, we found that HOXB13 immunohistochemistry had a 97% sensitivity and 99% specificity for prostatic origin. Taken together, our studies provide valuable insight into the expression pattern of HOXB13 during prostate development and cancer progression. Furthermore, our findings support the utility of HOXB13 as a diagnostic biomarker for prostate cancer, particularly to confirm the prostatic origin of advanced metastatic castration‐resistant tumors. © 2023 The Pathological Society of Great Britain and Ireland.

Sufficient conditions are given for planar cooperative maps to have the qualitative global dynamics determined solely on local stability information obtained from fixed and minimal period-two points. The results are given for a class of strongly cooperative planar maps of class $ C^1 $ C1 on an order interval. The maps are assumed to have a finite number of strongly ordered fixed points, and also the strongly ordered minimal period-two points. Some applications are included.

Die Paderborner Gastdozentur für Schriftstellerinnen und Schriftsteller ist eine der ältesten Poetikdozenturen in den deutschsprachigen Ländern. Zwanzig Jahre nach ihrer Gründung kamen 2002/03 im Laufe von zwei Semestern alle bis dahin nach Paderborn berufenen Poetikdozentinnen und -dozenten noch einmal zu Lesungen an die dortige Universität und traten so für das Publikum nacheinander in den Dialog. 2023, nach insgesamt 40 Jahren „Paderborner Gastdozentur für Schriftstellerinnen und Schriftsteller“, präsentieren die Veranstalter eine andere Art der Begegnung: zum einen mit den Beiträgen eines Symposiums zu den Werken Ingo Schulzes und Frank Witzels, die die 40. Paderborner Gastdozentur gemeinsam wahrgenommen und ihre Poetikvorlesungen buchstäblich im Dialog gehalten haben. Zum anderen versammelt das Sonderheft eine Reihe von Beiträgen, die jeweils zwei der in den zurückliegenden Jahren geladenen Poetikdozentinnen und -dozenten gemeinsam betrachten und deren Werke in einen spannungsvollen virtuellen Dialog eintreten lassen.

Subdivision of 2D polygons is the basis of many computational geometry algorithms and procedural modeling methods. Existing tools for space subdivision often require the assistance of users and cannot perform subdivision on all types of shapes (rectangular, axis-aligned, convex, and irregular). In this work, an open-source graphical desktop tool for drawing and automatic subdivision of arbitrary 2D polygons is introduced. An algorithm for subdivision of all shape types was developed. The algorithm is based on the usage of polygon bounding boxes, intersection edges and detection of polygons from newly formed edges. A dataset of 60 examples of all shape types was collected and successfully drawn by using the tool. Iterative subdivision was performed on all examples. Shape simplification was fully successful only for axis-aligned shapes. Partial simplification with leftover elements taking up less than 5% of overall polygon area was successful after 5 iterations for axis-aligned, and 10 iterations for convex and irregular shapes on average. This indicates that the tool and subdivision algorithm can be used for simplification of complex shape types with arbitrarily small leftover element area.
