Published: May 2023

With the continuous development of the information technology era, the big data industry is becoming one of the important criteria for measuring the comprehensive strength of the region. To better understand and explore the development status of the big data industry, it is essential to analyze the influencing factors of the big data industry, and then determine effective countermeasures that can promote the long-term development of the big data industry according to the influencing factors. This paper is committed to studying the influencing factors of the big data industry. By selecting 16 indicators, including policies and regulations, management institutions, technological innovation,talents distribution and per capita GDP in 31 provinces and municipalities directly under the Central Government in 2021, the factor analysis method is used to reduce 16 indicators into four factors affecting the government promotion, industrial ecosystem, industry platform and industrial resources affecting the big data industry, and establishes a multivariate linear regression model that affects the scale of the big data industry. This study found that there is a positive correlation between the industrial scale of the big data industry and the industrial ecosystem, government promotion and industrial resources. Combined with the specific situation and empirical analysis results of the development of provinces and cities across the country, this paper puts forward relevant suggestions in order to provide some help for the development of the big data industry in 31 provinces and cities across the country, hoping to provide a certain theoretical basis for the relevant departments in charge of the big data industry to formulate corresponding policies.

Integrated Supplier Selection and Distribution in Perishable Food Supply Chain
Authors: Zhang Yanrong 
Published: May 2023

In this study, we investigate the classical supplier selection and distribution problem in an integrated framework. The combined problem is originated from a local producing tomato sauce producer, whom we have been collaborated with since 2022. The suppler selection strategies are made based not only on each supplier’s product price and corresponding product quality, but also on the reliability and lead time of each protentional supplier. We proposed a quantitative framework with a conditional value-at-risk (CVaR) technique in the purpose of assessing the supplier performance. Then the selection and distribution decisions are simultaneously considered in a mixed integer linear programming (MILP) model, with the objective of maximizing the value added to the purchasing portfolio and distribution plans. Our experiments and computational results reveal that the combined approach is more beneficial than separated approaches. Finally, future research topics and managerial insights are provided.

BIOGRAFI SINGKAT DAN PENAFSIRAN AL-MARAGHI TERHADAP AYAT-AYAT INTERAKSI SOSIAL
Authors: Hamzah Hamzah , Hilmi Hilmi 
Published: May 2023

Konsep interaksi sosial yang terdapat di dalam al-Qur’an mempunyai banyak karakter dan macam-macamnya, setiap ayat yang berbicara tentang interaksi memiliki makna-makna yang bisa dibilang berbeda, namun jika diteliti dengan seksama itu semua adalah satu pemahaman. Seperti yang terdapat pada surah al-Mumtahanah ayat 8 bahwasannya interaksi sosial itu adalah proses timbal balik yang dilakukan oleh seluruh belahan manusia dengan tidak membeda-bedakan antara ras, suku, ideologi, negara bahkan agama. Dan Allah SWT tidak melarang atau bahkan menganjurkan untuk berinteraksi kepada siapapun. Dalam artian berintraksi kepada orang-orang yang tidak memerangi kalian. Dan Allah SWT juga menganjurkan untuk berbuat adil dengan mereka semuanya. Berbuat adil dalam masalah interaksi itu tidak ada batasannya, baik kepada sesama agama maupun lintas agama. Dengan syarat interaksi sosial yang terjalin itu tidak melanggar syari’at dan hukum-hukum Allah SWT. Imam Musthafa al-Maraghi memberikan penjelasan bahwasannya Interaksi sosial adalah suatu hubungan timbal balik yang dilakukan oleh sekelompok masyarakat. Baik antara individu dengan individu, individu dengan kelompok maupun kelompok dengan kelompok, yang mana tidak saling membedakan atara satu dengan yang lain, baik dari aspek sosial, kasta, posisi, suku, ekonomi bahkan agama.

L-Lysine is essential for human and animal nutrition and may be added to food and feed materials to improve the protein quality. It is utilized in human medicine, in cosmetics and in the pharmaceutical industry, particularly in the formulation of diets with balanced amino acid concentration and in amino acid infusions. Enhanced L-lysine production by UV irradiated and S-2-aminoethyl-L-cysteine resistant (AECR) mutants derived from Bacillus species, using agricultural products as carbon and nitrogen sources was studied. The L-lysine producing bacteria had already been isolated from Nigerian soil. They were purified and identified as B. subtilis PR13, B. subtilis PR9 and B. pumilus SS16, using cultural and biochemical characteristics. UV irradiated mutants were obtained by exposing the parent strains which include B. subtilis PR13, B. subtilis PR9 and B. pumilus SS16, to UV light while, AECR mutants were derived by exposing the parent strains to various concentrations of AEC. The mutants were screened for L-lysine production by cultivating in fermentation media. The results obtained showed that, UV mutants PRMU-8 and PRMU-14 derived from Bacillus subtilis PR13 accumulated higher lysine yield of 2.47 and 2.55 mg/ml compared to the wild type. Also, UV mutant MUPR-4 derived from Bacillus subtilis PR9 recorded a higher lysine yield of 1.77 mg/ml while, enhanced lysine yields of 1.96 and 2.34 mg/ml were observed in UV mutants SSMU-4 and SSMU-9 respectively. AECR mutant PRT-2 derived from Bacillus subtilis PR13, accumulated higher lysine yield of 2.35 mg/ml compared to the wild type. Enhanced lysine production of 1.47 and 1.32 mg/ml was observed in mutants ART-5 and ART-8 derived from B. subtilis PR9 while, mutant SRT-4 derived from B. pumilus SS16 recorded enhanced lysine accumulation of 2.18 mg/ml. The results obtained in the study showed that L-lysine production by some UV irradiated and AECR mutants was enhanced.

Published: May 2023

AbstractFerroptosis is a form of programmed cell death and plays an important role in many diseases. Dihydroorotate dehydrogenase (DHODH) and glutathione peroxidase 4 (GPX4) play major roles in cell resistance to ferroptosis. Therefore, inactivation of these proteins provides an excellent opportunity for efficient ferroptosis‐based synergistic cancer therapy. In this study, a multifunctional nanoagent (BPNpro) containing a GPX4 targeting boron dipyrromethene (Bodipy) probe (BP) and a DHODH targeting proteolysis targeting chimera (PROTAC) is reported. BPNpro is prepared using a nanoprecipitation method in the presence of a thermoresponsive liposome, where BP is encapsulated inside and the cathepsin B (CatB)‐cleavable PROTAC peptide (DPCP) is modified on the outer surface. In the presence of near‐infrared (NIR) photoirradiation, BPNpro is melted and BP is released in tumor cells. Subsequently, BP inhibits the activity of GPX4 by covalently bonding with the selenocysteine at the enzyme active site. In addition, DPCP achieves sustained degradation of DHODH upon activation by CatB overexpressed in the tumor. The synergistic deactivation of GPX4 and DHODH induces extensive ferroptosis and subsequent cell death. In vivo and in vitro studies clearly show that the proposed ferroptosis therapy provides excellent antitumor effect.
Highly Stretchable and Sensitive Strain Sensor Based on Porous Materials and Rhombic‐Mesh Structures for Robot Teleoperation

Published: May 2023

AbstractWearable sensors for human motion capture offer a promising human–robot interface to control robots in the teleoperation scenario, where robots could function as the second body of human operators to fulfill tasks remotely and accurately. In this paper, a novel strain sensor based on a soft polyurethane (PU) sponge and carbon nanotubes (CNT) is designed for motion capture of human joints. The unique 3D porous microstructure of the PU‐CNT sponge provides the sensor with high sensitivity. To bridge the gap between the high sensitivity and high stretchability of the strain sensor, a rhombic‐mesh structure with optimized geometric parameters, in conjunction with a pre‐compression design, is proposed for strain sensor prototyping, which endows the sensor with an extra elongation rate during the stretching process. The proposed PU‐CNT strain sensor manifests promising sensing performance with a stretchability of up to 300% and a maximum gauge factor of 3893, together with long‐term durability, low detection limit, and fast response capacity. Finally, the validation of the strain sensor is carried out by deploying the sensor on a human elbow to realize the teleoperation of a robot arm, which could be monitored through the digital twin model of the robot in a real‐time manner.
