La Alhambra de Granada: un fractal orientalista en clave poscolonial. Los puntos de vista local y árabe
Authors: González Alcantud José Antonio , Rojo Flores Sandra 
Published: May 2023

Este artículo se centra en la Alhambra, de Granada, y de manera colateral en al-Ándalus, en varias de sus direcciones y dimensiones, enmarcadas todas ellas en la reflexión poscolonial. Se sitúa el monumento nazarí en el discurso orientalista clásico para destacar desde el principio su carácter “vivo”. Esto es perceptible incluso en las primeras versiones de los viajeros extranjeros, con Washington Irving como el principal valedor de su viveza, y quien llamó a sus habitantes “hijos de la Alhambra”. en esa línea interpretativa, los autores de este trabajo participaron en el proyecto Memoria oral de la Alhambra, que ofrece la perspectiva local, granadina, del monumento. A través de ella, se pone de relieve uno de los aspectos pocas veces vistos en relación con la Alhambra considerada por regla general como un reflejo de lo paradisíaco, como es su carácter conflictual, guiado tanto por intereses políticos como por apropiaciones identitarias. En la segunda parte, se analiza el problema de la Alhambra en relación con la imagen de al-Ándalus. Aquí se refuerza la crítica a las tesis de E. Said —el Oriente como producto intencionado de Occidente—, donde al-Ándalus queda como una laguna que el autor no conceptualiza. Por otra parte, en contraste con el punto de vista local, se introducen las miradas de los viajeros y los intelectuales árabes que arrancan con la exaltación nostálgica de la patria perdida posterior a la expulsión de moros y judíos de la península, visión que se ha instalado contemporáneamente en el nacionalismo árabe. Esta idea se adecua a realidades en apariencia distintas, como la de Medio Oriente y América latina, pero que comparten rasgos como el exilio, la pérdida y la nostalgia. El artículo concluye con la reflexión sobre cómo los actuales “propietarios del problema”; es decir, los granadinos, confrontan e incluso comparten en alguna medida con los intelectuales árabes el fractal —metáfora física de connotaciones culturales— “Alhambra”.

Entropy- A Tale of Ice and Fire
Authors: Hirica Iulia-Elena , Pripoae Cristina-Liliana , Pripoae Gabriel-Teodor , Preda Vasile 
Published: May 2023

Abstract
In this review paper, we recall, in a unifying manner, our recent results concerning the Lie symmetries of nonlinear Fokker-Plank equations, associated to the (weighted) Tsallis and Kaniadakis entropies. The special values of the Tsallis parameters, highlighted by the classification of these symmetries, clearly indicate algebraic and geometric invariants which differentiate the Lie algebras involved. We compare these values with the ones previously obtained by several authors, and we try to establish connections between our theoretical families of entropies and specific entropies arising in several applications found in the literature.
We focus on the discovered correlations, but we do not neglect dissimilarities, which might provide -in the future-deeper details for an improved extended panorama of the Tsallis entropies.

Hyperbolic Tangent Like Relied Banach Space Valued Neural Network Multivariate Approximations
Authors: Anastassiou George A. 
Published: May 2023

Abstract
Here we examine the multivariate quantitative approximations of Banach space valued continuous multivariate functions on a box or ℝ
N
, N ∈ ℕ, by the multivariate normalized, quasi-interpolation, Kantorovich type and quadrature type neural network operators. We treat also the case of approximation by iterated operators of the last four types. These approximations are derived by establishing multidimensional Jackson type inequalities involving the multivariate modulus of continuity of the engaged function or its high order Fréchet derivatives. Our multivariate operators are defined by using a multidimensional density function induced by a hyperbolic tangent like sigmoid function. The approximations are pointwise and uniform. The related feed-forward neural network is with one hidden layer.
Reforming the Public Sector in Eastern European and Former Soviet Union Countries: A Systematic Literature Review
Authors: Vakulenko Veronika , Mattei Giorgia 
Published: May 2023

ABSTRACT
This article applies a systematic literature-based approach to select, analyze, and categorize publications appearing on public sector management (PSM) reforms in Eastern European (EE) and former Soviet Union (FSU) countries. Findings of the literature review reveal the complexity of reformation in the region and point to the multilayered character of the reform processes, including design of the reform content, implementation, and evaluation of achieved results. The analysis, also shows that the reforms’ results are uneven and somewhat controversial. This article contributes by systematizing literature on transforming PSM in EE and FSU countries; analyzing the trajectories of the dominant reforms and finding overlooked topics; providing avenues for future research; and by contextually covering twenty-eight countries that experienced economic transition and significant societal transformations.

Authors: Saad Aberkane Mohammed , Youness Farhane 
Published: May 2023

Abstract
Product Lifecycle Management remains a strategy that aims to strengthen the capabilities and competitive advantages of the company. Its implementation and its adoption depend on the problems that are brought back to be solved by this tool as well as its acceptance by the companies that will implement it. Hence, we like to introduce this approach within the cottage industry to improve its competitiveness. For this, we are going to present this article as being the first step towards the introduction of this strategy within the craft sector. So, we aim to investigate the problems faced by the craft sector, the levers favoring the establishment of this kind of approach and to analyse the independence between the problems investigated, the nature of the companies interviewed and their sector of activity. Data was gathered from surveys of 132 craft industries the primary data analysis was performed using excel and SPSS techniques and chi square test. The results affirm that the management and communication problems, as well as problems related to the raw material waste, are the most dominant in the sector. Moreover, our study shows that the problems faced by the sector are independent towards the nature of the company and the sector of activity.
An Inventory Model with Price and Credit Installments-Dependent Demand
Authors: Hasan Rakibul , Siddiqa Ayesha , Roy Tutul Chandra , Amin Al , Daryanto Yosef 
Published: May 2023

Abstract
Financial capability is one of the primary drivers for buyers to make purchases. Therefore, sellers must set an optimum selling price and consider trade credit facilities to attract more demand. This paper proposes an inventory decision model in which customer demand depends on the price and number of credit installments to serve low-abled buyers. This study has developed a demand function with a positive impact on installment policies and the effect of the selling price. Two models have been formulated to optimize the selling price and positive stock time, m total profit, with and without installment policies. Then, numerical examples and sensitivity analysis illustrate the proposed model for different cases. The study has found that the selling price and positive stock time can be optimized. Profits can be higher in the case of an installment facility than in the case without an installment facility. It shows positive responses from the buyer to the installment policy.

Abstract
Circular economy (CE) is an interesting approach by many countries to address global environmental problems while gaining economic benefits. The implementation of CE is expected to minimize the use of resources and materials, thus contributing to sustainable development. Much literature has discussed CE assessment indicators and their evaluation, however to date, no single indicator has been proposed that can comprehensively measure the macro level of CE implementation. This study aims to develop a CE index to measure CE implementation at macro levels. In addition, it provides an overview of the impact of CE implementation on the financial, social, and environmental aspects of the economy. To this end, first, an in-depth literature review and descriptive analysis is conducted to identify existing global CE indicators and classify them into financial, social, and environmental categories based on available primary and secondary data. Then, the CE index is constructed using a mathematical equation by considering the CE framework, a single indicator of each aspect as a variable, and the variable’s weighting. Finally, the CE index is applied to evaluate the level of CE implementation of CE in Indonesia at macro level. This index is expected to be a valuable tool for measuring CE implementation and therefore improving CE performance.

Authors: Imajo Satoshi , Tanabe Yoshinori , Nakamura Nobue , Honda Mitsugi , Kuroda Masahiro 
Published: May 2023

Abstract

Introduction
In the standardization of panoramic radiography quality, the education and training of beginners on panoramic radiographic imaging are important. We evaluated the relationship between positioning error factors and multiple image analysis results for reproducible panoramic radiography.

Material and methods
Using a panoramic radiography system and a dental phantom, reference images were acquired on the Frankfurt plane along the horizontal direction, midsagittal plane along the left–right direction, and for the canine on the forward–backward plane. Images with positioning errors were acquired with 1–5 mm shifts along the forward– backward direction and 2–10° rotations along the horizontal (chin tipped high/low) and vertical (left–right side tilt) directions on the Frankfurt plane. The cross-correlation coefficient and angle difference of the occlusion congruent plane profile between the reference and positioning error images, peak signal-to-noise ratio (PSNR), and deformation vector value by deformable image registration were compared and evaluated.

Results
The cross-correlation coefficients of the occlusal plane profiles showed the greatest change in the chin tipped high images and became negatively correlated from 6° image rotation (r = −0.29). The angle difference tended to shift substantially with increasing positioning error, with an angle difference of 8.9° for the 10° chin tipped low image. The PSNR was above 30 dB only for images with a 1-mm backward shift. The positioning error owing to the vertical rotation was the largest for the deformation vector value.

Conclusions
Multiple image analyses allow to determine factors contributing to positioning errors in panoramic radiography and may enable error correction. This study based on phantom imaging can support the education of beginners regarding panoramic radiography.
Evaluation of muscle elasticity in patients with end-stage renal disease complicated with sarcopenia by real-time shear wave elastography multipoint measurement
Authors: Guo Li , Ran Lei , Zhang YaPu , Guo XiaoHong , Li Jing , Gong YouLan , Zhou Xuan , Wu XiaoXi 
Published: May 2023

Abstract

Background
To analyze the value of real-time shear wave elastography (SWE) multi-point measurement in the evaluation of muscle elasticity in patients with end-stage renal disease (ESRD) complicated with sarcopenia.

Methods
We enrolled 169 ESRD patients treated as the research objects from January 2019 to February 2022. According to whether they were complicated with sarcopenia, the patients were divided into sarcopenia group (n=63) and non-sarcopenia group (n=106). The Young’s modulus and shear wave velocity (SWV) of muscles in relaxed and contracted states were measured by SWE technology in the two groups.

Results
Logistic regression analysis showed that age and hs-CRP were independent risk factors for sarcopenia in ESRD patients (P<0.05), while BMI, muscle thickness, Young’s modulus in stretched state and SWV in stretched state were protective factors for sarcopenia in ESRD patients (P<0.05). BMI, muscle thickness, Young’s modulus in extended state, SWV in extended state and Young’s modulus in rest state were all negatively correlated with age and hs-CRP (P<0.05), while there was a significant positive correlation between age and hs-CRP (P<0.05). Independent influencing factors were used to construct the prediction model of nomogram. The consistency index (C-index) was 0.845 (95% CI: 0.830~0.857), and the AUC of ROC curve was 0.852 (95% CI: 0.836~0.871), which had good discrimination.

Conclusion
SWE could accurately evaluate the muscle elasticity of ESRD patients, so as to reflect the changes of muscle mass and stiffness of patients, and could provide the important imaging indicator for the prediction of sarcopenia.
Diagnostic values of glial fibrillary acidic protein, neuron-specific enolase and protein S100β for sepsis-associated encephalopathy
Authors: Cao Zhigang , Huang Xiang , Chen Feixiang 
Published: May 2023

Abstract

Background
To investigate the expressions of glial fibrillary acidic protein (GFAP), neuron-specific enolase (NSE) and protein S100β and their diagnostic values for sepsis-associated encephalopathy (SAE).

Methods
One hundred patients with sepsis treated from August 2021 to August 2022 were included. They were assigned to a sepsis group (n=65) and an SAE group (n=35), while 50 healthy volunteers physically examined in the same period were enrolled as a control group. The levels of GFAP and NSE were detected by enzyme-linked immunosorbent assay, and that of S100β was determined by transmitted immunoturbidimetric assay. The expressions of GFAP, NSE and S100β in patients with SAE were detected, and their correlations and diagnostic values were analyzed.

Results
Compared to patients with mild and moderate SAE, those with severe SAE had higher levels of GFAP, NSE and S100β (P<0.05). The levels of GFAP, NSE and S100β were higher in coma patients than those with consciousness disturbance, and they were higher in patients with a poor prognosis than those with a good prognosis (P<0.05). Positive correlations were identified between GFAP and NSE (r=0.573, P=0.001), GFAP and S100β (r=0.468, P=0.005), and NSE and S100β (r=0.540, P=0.001) expression in patients with SAE. Compared with GFAP, NSE and S100β alone, their combination had higher sensitivity and lower specificity for diagnosing SAE (P<0.05).

Conclusions
There are correlations among GFAP, NSE and S100β, and the combined detection of these three indicators is highly valuable for the diagnosis of SAE.

Published: May 2023

Abstract

Introduction
In this study, we seek to determine the association between the polymorphism of the ADIPOQ (rs1501299) gene and adiponectin levels in gestational diabetes mellitus (GDM) patients.

Methods
The study participants included 200 pregnant women, 100 healthy subjects as the control group, and 100 having GDM as the case group. The enzyme-linked immunosorbent assay (ELISA) was used to examine adiponectin levels. The polymerase chain reaction-restriction length polymorphism (PCR-RFLP) was also used for genotyping examination.

Results
Findings showed that GDM patients had significantly lower serum adiponectin levels (p=0.001). The T/T genotype ho-mozygotes prevalence for rs1501299 polymorphism was significantly lower in GDM patients. (p=0.047).

Conclusion
Low serum adiponectin levels are associated with GDM. The T allele of the rs1501299 (+276 G/T) polymorphism of the ADIPOQ gene protects against GDM.
Changes in C-reactive protein, erythrocyte sedimentation rate, human leukocyte antigen-B27, and immunoglobulins A, G, M in patients with ankylosing spondylitis
Authors: Zhu Lixiu , Zhou Sujuan , Lin Ye , Ye Zhen , Tang Yirong , Chen Renli 
Published: May 2023

Abstract

Background
To explore the changes in C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), human leukocyte antigen-B27 (HLA-B27), and immunoglobulin (Ig) (IgA, IgG, and IgM) in patients suffering from ankylosing spondylitis (AS).

Methods
A total of 232 patients with axial spondyloarthritis admitted from January 2020 to December 2021 were selected, among whom 132 were AS patients (AS group) and 100 were non-AS cases (non-AS group). Meanwhile, 100 healthy subjects undergoing physical examination were included as a control group. Peripheral blood was collected to detect the levels of CRP, ESR, HLA-B27, IgA, IgG, and IgM.

Results
The positive rates and levels of CRP, ESR, HLA-B27, IgG, and IgM in non-AS and AS groups were significantly higher, and the IgA level of the AS group was higher than those of the control group (P<0.05). The AS group had significantly higher positive rates and levels of CRP, ESR, HLA-B27, and IgA than those of the non-AS group (P<0.05). The levels of HLA-B27, ESR and CRP had positive correlations with those of IgA, IgG and IgM (P<0.05). The area under the curve (AUC) of HLA-B27 with a cut-off value of 53.18 U/mL for the diagnosis of AS was 0.879. AUC of ESR with a cut-off value of 23.83 mm/h for the diagnosis of AS was 0.811. AUC of CRP with a cut-off value of 14.35 mg/L for the diagnosis of AS was 0.745. With the cut-off values of 2.75 g/L, respectively, AUC of IgA for the diagnosis of AS were 0.668. AUC of the combined diagnosis was 0.929 (P<0.05).

Conclusions
AS patients have abnormally elevated levels of HLA-B27, ESR, CRP, and IgA, and the combined detection has a higher diagnostic value. The abnormal increase in IgA, IgG, and IgM is positively correlated with rheumatic inflammation marker HLA-B27, CRP, and ESR.
Vancomycin-resistant enterococci isolated in tertiary care in Southern Thailand: Prevalence and characterization of biofilm formation
Authors: Saengsuwan Phanvasri , Singkhamanan Kamonnut , Kawila Soontara , Romyasamit Chonticha 
Published: May 2023

Abstract

Introduction
Vancomycin-resistant enterococci (VRE) are important causative agents of healthcare-associated infections. This study investigated the prevalence of VRE isolates of clinical specimens from a tertiary hospital in Southern Thailand and their biofilm formation and associated virulence factors.

Methods
This retrospective study was conducted from February 2011 to March 2021 at a 1,000-bed tertiary care hospital in Songkhla Province in Southern Thailand.

Results
In total, 95 VRE isolates were collected. Urine had the highest VRE prevalence (38%), followed by pus or secretions (23%) and the digestive tract (19%). VRE infections were most common in medical (45%) and surgical wards (19%). VRE strains were equally resistant (85–100%) to the six classes of antibiotics commonly used in a tertiary care hospital. Biofilms were produced by 73% of the multidrug-resistant strains; however, 93% of VRE isolates lacking hyl were highly capable of producing biofilms.

Conclusions
No relationship was observed between virulence genes and biofilm formation. Thus, efforts to establish appropriate treatment and control measures are necessary, as distinctive VRE characteristics are relevant to the treatment of enterococcal infections in hospitals.

Published: May 2023

Abstract
Identification of predictive biomarkers for the evolution of critically ill COVID-19 patients would represent a milestone in the management of patients and in human and financial resources prioritization and allocation. This retrospective analysis performed for 396 critically ill COVID-19 patients admitted to the intensive care unit aims to find the best predictors for fatal outcomes in this category of patients. The inflammatory and metabolic parameters were analyzed and Machine Learning methods were performed with the following results: (1) decision tree with Chi-Square Automatic Interaction Detector (CHAID) algorithm, based on the cut-off values using ROC Curve analysis, indicated NLR, IL-6, comorbidities, and AST as the main in-hospital mortality predictors; (2) decision tree with Classification and Regression Tree (CRT) algorithm confirmed NLR alongside CRP, ferritin, IL-6, and SII (Systemic Inflammatory Index) as mortality predictors; (3) neural networks with Multilayer Perceptron (MLP) found NLR, age, and CRP to be the best mortality predictors. Structural Equation Modeling (SEM) analysis was complementarily applied to statistically validate the resulting predictors and to emphasize the inferred causal relationship among factors. Our findings highlight that for a deeper understanding of the results, the combination of Machine Learning and statistical methods ensures identifying the most accurate predictors of in-hospital mortality to determine classification rules for future events.
