Abstract
The threats of nonrenewable energy consumption and environmental disruption caused by the extensive use of metals and polymers derived from petroleum have prompted the development of eco-friendly, high-performance, and long-lasting structural materials. After various treatments, cellulose materials exhibit exceptional properties such as high strength, fire resistance, hydrophobic properties, and thermal stability. Cellulose-based structural materials have excellent mechanical strength and the distinct advantages of being lightweight, inexpensive, and energy efficient. This review summarizes the recent progress in the preparation methods and properties of high-performance cellulose structural materials such as high-strength cellulose structural materials, thermal insulation cellulose structural materials, flame-retardant cellulose structural materials, hydrophobic cellulose structural materials, cellulose structural material with electrical properties, and other cellulose structural materials. The future of high-performance cellulosic structural materials and the prospective of their development are concluded.

Abstract

Objectives
In nasopharyngeal carcinoma (NPC), the main factors for treatment failure are local recurrence and metastasis. Vasculogenic mimicry (VM), formation by invasive cancer cells mimicking the vasculogenic network, is strongly correlated with tumor therapy resistance and distant metastasis. CSF-1R was substantially expressed in NPC patients with a poor prognosis, according to an earlier study of ours. However, whether CSF-1R affects progression through vasculogenic mimicry deserves consideration.

Methods
By cultivating NPC cells that had CSF-1R overexpression in three-dimensional culture and labeling the NPC xenografts with CD34-PAS vasculogenic mimicry markers, the effect of CSF-1R on VM formation, migration, and invasion of NPC cells was evaluated. Finally, the underlying mechanisms were investigated by western blot.

Results

In vitro and in vivo, overexpressing CSF-1R in NPC cells causes the development of vessel-like structures. Meanwhile, NPC cells migrated and invaded more readily in the Transwell experiment when CSF-1R was highly expressed. Mechanistically, our research indicates that CSF-1R may control cell plasticity by activating the PI3K/AKT signaling pathway, promoting the formation of VM in these cells by facilitating the epithelial-mesenchymal transition.

Conclusions
CSF-1R in NPC progression by increasing VM production to increase nutrient supply to tumor cells and promote cancer cell invasion. Furthermore, these findings suggest that CSF-1R is a new promising therapeutic target aimed at treating VM in NPC.
Local performance evaluation of AI-algorithms with the generalized spatial recall index
Authors: Müller Patrick , Braun Alexander 
Published: May 2023

Abstract
We have developed a novel metric to gauge the performance of artificial intelligence (AI) or machine learning (ML) algorithms, called the Spatial Recall Index (SRI). The novelty is the spatial resolution of a standard performance indicator, as a Recall value is assigned to each individual pixel. This generates a distribution of the performance of a given AI-algorithm with the resolution of the images in the dataset. While the mathematical basis has already been presented before, here we demonstrate the usage on more datasets and delve into in-depth application examples. We examine both the MS COCO and the Berkeley Deep Drive datasets, using a state-of-the-art object detection algorithm. The dataset is degraded using a physical-realistic lens-model, where the optical performance varies over the field of view, as a real camera would. This study highlights the usefulness of the SRI, as every image has been taken by realistic optics. A generalization, the GSRI is introduced, from which we derive SRIA, weighting with object area and SRIrisk intended for autonomous driving. Finally, these metrics are compared.

UMA REVOLUÇÃO ESTÉTICA: O ABSTRACIONISMO DE INAH (1959-1979)
Authors: Corrêa e Silva Rebecca 
Published: May 2023

Antes mesmo do abstracionismo se consolidar como nova linguagem pictórica no Rio Grande do Sul, Inah D’Ávila Costa (1915-1998) iniciou o que viria a ser uma revolução nos modos de ensinar, fruir e produzir arte na cidade de Pelotas (RS). Apesar da sua relevância na constituição do sistema das artes pelotense, atestada em estudos recentes, Inah ainda é pouco conhecida, se comparada à notoriedade alcançada pelos seus colegas homens de profissão. Para compreender as possíveis razões desse apagamento, recorremos à História das Mulheres (PERROT, 2008) sobre a perspectiva de gênero (SCOTT, 1992; 1995), observando as matizes interseccionais deste conceito através das categorias raça/etnia & classe e geração/ faixa etária & estado civil. O texto apresenta um recorte de vinte anos (1959-1979), significativo do percurso da pintora, posto que foi o seu período maior atividade. A análise deste período foi baseada em fontes de suportes diversos, como cartas; reportagens e críticas dos jornais locais e no depoimento oral de uma sobrinha.Palavras-chave: Gênero; História das Mulheres; Pintura abstrata.UNA REVOLUCIÓN ESTÉTICA: EL ABSTRACIONISMO DE INAH (1959-1979)Resumem: Antes mismo del abstraccionismo consolidarse como nuevo lenguaje pic­tórico en Rio Grande del Sur (RS), Inah D’Ávila Costa (1915-1998) empezó lo que vendría a ser una revolución en las maneras de enseñar, fruir y producir arte en la ciudad de Pelotas /RS.

Establishing the neural mechanisms responsible for the altered global states of consciousness during anesthesia and dissociating these from other drug-related effects remains a challenge in consciousness research. We investigated differences in brain activity between connectedness and disconnectedness by administering various anesthetics at concentrations designed to render 50% of the subjects unresponsive. One hundred and sixty healthy male subjects were randomized to receive either propofol (1.7 μg/ml;n= 40), dexmedetomidine (1.5 ng/ml;n= 40), sevoflurane (0.9% end-tidal;n= 40), S-ketamine (0.75 μg/ml;n= 20), or saline placebo (n= 20) for 60 min using target-controlled infusions or vaporizer with end-tidal monitoring. Disconnectedness was defined as unresponsiveness to verbal commands probed at 2.5-min intervals and unawareness of external events in a postanesthesia interview. High-resolution positron emission tomography (PET) was used to quantify regional cerebral metabolic rates of glucose (CMRglu) utilization. Contrasting scans where the subjects were classified as connected and responsive versus disconnected and unresponsive revealed that for all anesthetics, except S-ketamine, the level of thalamic activity differed between these states. A conjunction analysis across the propofol, dexmedetomidine and sevoflurane groups confirmed the thalamus as the primary structure where reduced metabolic activity was related to disconnectedness. Widespread cortical metabolic suppression was observed when these subjects, classified as either connected or disconnected, were compared with the placebo group, suggesting that these findings may represent necessary but alone insufficient mechanisms for the change in the state of consciousness.SIGNIFICANCE STATEMENTExperimental anesthesia is commonly used in the search for measures of brain function which could distinguish between global states of consciousness. However, most previous studies have not been designed to separate effects related to consciousness from other effects related to drug exposure. We employed a novel study design to disentangle these effects by exposing subjects to predefined EC50doses of four commonly used anesthetics or saline placebo. We demonstrate that state-related effects are remarkably limited compared with the widespread cortical effects related to drug exposure. In particular, decreased thalamic activity was associated with disconnectedness with all used anesthetics except for S-ketamine.
Numerical studies for effect of geometrical parameters on water jet pump performance via entropy generation analysis
Authors: Helios Muhammad Penta , Asvapoositkul Wanchai 
Published: May 2023

This paper presented an implementation of entropy generation analysis in the main flow field of a water jet pump via the CFD method. This study aimed to identify the inefficient location of energy conversion and to analyse entropy generation sources in each region of the water jet pump. The 2D-axisymmetric model and realisable k-ε (RKE) turbulence model at steady-state conditions were performed to validate jet pump performance and to assess the entropy generation. Likewise, the effects of the projection ratio and throat-aspect ratio as independent parameters were investigated. As a result, the throat is the most inefficient part due to the high total entropy generation rate, following by diffuser part. Also, the entropy generation rate was assessed dominant than viscous dissipation due to the turbulent dissipation, which was caused by a turbulent shear stress layer of mixing the streams. In conclusion, the projection ratio influenced the growth of the shear stress layer as well as the entropy generation. Further, the throat-aspect ratio affected the distribution of entropy generation in the throat section. An appropriate combination of both parameters has an impact on the jet pump performance improvements reducing the entropy generation rate in the future.

Irregular coloring is a proper coloring and each vertex on a graph must have a different code. The color code of a vertex v is where and is the number of vertices that are adjacent to v and colored i. The minimum k-color used in irregular coloring is called the irregular chromatic number and denoted by . In this paper, we discuss the irregular chromatic number for the bull graph, pan graph, sun graph, peach graph, and caveman graph.
Characteristic of Quaternion Algebra Over Fields
Authors: Faldiyan Muhammad , Carnia Ema , Supriatna Asep K. 
Published: May 2023

Quaternion is an extension of the complex number system. Quaternion are discovered by formulating 4 points in 4-dimensional vector space using the cross product between two standard vectors. Quaternion algebra over a field is a 4-dimensional vector space with bases and the elements of the algebra are members of the field. Each element in quaternion algebra has an inverse, despite the fact that the ring is not commutative. Based on this, the purpose of this study is to obtain the characteristics of split quaternion algebra and determine how it interacts with central simple algebra. The research method used in this paper is literature study on quaternion algebra, field and central simple algebra. The results of this study establish the equivalence of split quaternion algebra as well as the theorem relating central simple algebra and quaternion algebra. The conclusion obtained from this study is that split quaternion algebra has five different characteristics and quaternion algebra is a central simple algebra with dimensions less than equal to four.
