Optimization Policy of Inventory Model under the Effects of Learning and Imprecise Demand Rate
Authors: Yadav Dharmendra , Kumari Rachna , Singh S.R.
Published: January 2023

It is a natural phenomenon that the performance of a system engaged in a repetitive process improves with time. In literature, this phenomenon is referred to as the ï¿½learning effectï¿½. In this paper we analyze the impact of this effect on optimal strategy of inventory problem. Here, we consider the learning effects on holding cost, ordering cost and number of defective items present in each lot. By incorporating these learning effects, the decision maker can establish a model to optimize the capacity of organization and increase the efficiency of inventory system. We seek to maximize the profit and obtain the optimum lot size in each shipment under the effect of learning and by assuming that the demand rate is imprecise in nature. We use the Extension Principle to obtain the membership function of profit and centroid method for defuzzification. We observe that learning effect produce direct impact on optimal solution. At the end, numerical example is illustrated and sensitive analysis is performed.
An Economic Order Quantity Model With n-Levels of Storage
Authors: K.V.S. Sarma  , Prasuna. E
Published: January 2023

This paper deals with a mathematical model to determine the Economic Order Quantity (EOQ) of a single item inventory system, when the Own Warehouse (OW) of the management has insufficient space. If the received stock Q exceeds the capacity of the OW, the management considers storing the stock in n Rented Warehouses each with finite capacity. Each Rented Warehouse (RW) is assumed to carry a higher holding cost than that of the OW. Considering all the n warehouses as n-storage points for the single item inventory, a two-phase mathematical model is developed to determine the EOQ. The principle of Shortest Processing Time (SPT) sequencing has been used in the first phase to find the optimal depletion sequence for the warehouses. The second phase deals with the building of cost function for the inventory cycle. The EOQ is determined and the functioning of the model is numerically illustrated.
PYTHAGOREAN TRIPLES: THE CONNECTION BETWEEN NUMBER THEORY, GEOMETRY AND ALGEBRA THROUGH THE VEDIC MATHEMATICS PERSPECTIVE
Authors: Gokhale Prajakti
Published: January 2023

The ancient mathematics of India is an amalgamation of poetry, literature, art, architecture and also scientific thought. Looking at Sanskrit literature, the literature developed for expressing mathematical thoughts and ideas have their special place in linguistic evolution. We can observe that the technical Sanskrit language evolved through the centuries as rich mathematical ideas developed. For the expression of these ideas, the strong technical vocabulary ofthe language was needed. This language approach was very different, it can be compared to today’s technical vocabulary we have developed for modern computer which was alien even 30 years ago. The ancient technical vocabulary was difficult for contemporary scholars to understand and hence mathematical ideas remain hidden in it for a longer time. The new approach of mathematics invented and developed by Bharti Krishna Tirtha, which did not show such language barriers. It was written in the form of one-line simple Sanskrit words called ‘sutra’. The deep meaning of sutra, its connection and its interpretation to different branches of mathematics and also the deep spiritual thought behind the sutra, is worth studying and researching. In my research paper, I will be presenting the technicalities of ancient mathematical language and exploring the method of Pythagorean triples through the Vedic mathematics ‘sutras’ formulated by Bharati Krishna Tirtha. I will also be highlighting the applications of triples in current mathematical scenario, to connect the different fields of mathematics, implication of which is making mathematics easy, conceptually clear and alsoperceived with a new dimension of thought.
Large Number System from Vedas and Vedic Literature
Authors: Thakur Rajesh Kumar
Published: January 2023

Hinduism is undoubtedly the oldest religion of the world and though there are disagreement over the period amongst some historian but it was during 1900 to 1500 BC when Hindu religion came into existence. The foremost religious text of Hindu is Vedas and the origin of the Vedas can be traced back as far as 1500 BCE, when a large group of Aryans crossed the Hindu Kush Mountains and came to Indian subcontinent. The Vedas are full of knowledge.The Vedas have guided the Indian civilization for thousands of years and the Four Vedas are the pillar of Hinduism. The very word Veda has a derivational meaning – the fountainhead and illimitable storehouse of all knowledge. This article will only focus on the mathematical content available in Vedas, Puranas, Ramayana and Mahabharata. In Rig Veda and Atharva Veda, there are several instance where numbers in the power of tens, even numbers, odd numbers, multiples of four, value of pi, mathematical operation such as addition, subtraction, multiplication and division have been discussed not in the way we use in our courses but the presence of larger number even up to 1060 is evident. The speed of light, about seven colourful rays of sunlight all these are enough to make a belief that Vedas have put a strong foundation of number system and decimal system. Not even that, even geometrical knowledge found in Sulbha sutra as par excellence and many of them have origin prior to Greek mathematician to whom we owe everything.
Entire development of the human brain through Vedic Mathematics
Authors: Asrani Ravi
Published: January 2023

The Vedic Mathematics system provides us with a large number of options at each stage of working. Depending upon the pattern of the problem, one of these options is going to give the result with very little effort and in minimum time. Therefore the very first step is to look for the pattern of the problem which essentially involves systematic use of the right half of the brain. Then the logical computations are done by the left half. Even while computing, due to various options available, the mind is always kept alert to pick up the path of least effort. Thus while practicing the Vedic Maths, Human brain gets the systematic training of integrated functioning of the two halves of the brain. Due to multidimensional thinking, overall development of human brain takes place through Vedic Mathematics. Study was conducted on two samples of 25 students each. They are 6th to 10th grade students. The sample for the study was selected on the basis of the random sampling technique. I have performed experiments on them. The results of statistical t test of significance of difference in means indicate that Vedic Mathematics can help any person achieve greater skill, comprehension and efficiency in mathematics. These methods can improve logical thinking, computational speed, creativity and positive Mathematics attitude

The implementation of this study aims to ensure the effectiveness of the Integrating Society, Science, Environment, Technology, and Collaborative Mind Mapping (ISSETCM2) learning model on mathematical literacy skills in terms of adversity quotient (AQ). This research design is quasi-experimental, with the population being all eighth-grade students in the academic year 2021/2022. The research sample was selected by cluster random. The average value of the mathematical literacy ability of the experimental class students is 72.03, and that of the control class is 50.34. Based on data interpretation and analysis of variance (ANOVA) of two-path unequal cells with a significant value of . The value of Sig is 0.001, so Sig . Based on the data, there are differences in the results of mathematical literacy skills between the learning model (ISSETCM2) and direct instruction learning models. Also, there are differences in adversity quotient categories (climbers, campers, and quitters) on mathematical literacy abilities. There is no interaction between learning model factors and adversity quotient on the results of students' mathematical literacy abilities. From these data, it can be concluded that there is an effect of the ISSETCM2 learning model on mathematical literacy skills in terms of the adversity quotient of class VIII. The research results show that each student has a different adversity quotient, which can affect students' mathematical reasoning abilities. For this reason, students need to know the adversity quotient to maximize their abilities.

Compromiso corporativo e inclusión social de adultos vulnerables
Authors: Llorente Barroso Carmen , Anzanello Carrascoza João Luis , Ferreira Ivone Ferreira
Published: January 2023

La importancia que progresivamente han adquirido el envejecimiento y la discapacidad en las sociedades desarrolladas ha motivado iniciativas que procuran despertar y/o fortalecer el compromiso corporativo e institucional con la inclusión de los adultos vulnerables. Para alcanzar este propósito es imprescindible eliminar los estereotipos negativos sobre la vejez y la discapacidad, así como romper las diferentes barreras de exclusión que frenan la participación ciudadana de colectivos afectados por tales estigmas. En esta línea, los objetivos de desarrollo sostenible (ODS) han impulsado marcos normativos e iniciativas corporativas encaminadas hacia la inclusión de los públicos más vulnerables. Sin embargo, no siempre existe consonancia entre el sector privado, el ámbito institucional y los ciudadanos para poder desarrollar una estrategia integral que conduzca a la deseada plena inclusión. La innovación tecnológica y la digitalización parecen tener un papel determinante en el camino hacia la integración social de seniors y personas con discapacidad, si bien, estos grupos sociales suelen verse especialmente afectados por brechas digitales que amplifican sus desigualdades y limitan todavía más su participación socio-política. Este monográfico busca impulsar un mayor conocimiento sobre los diferentes aspectos estratégicos que permitan a empresas, instituciones y administraciones avanzar en políticas orientadas a la plena inclusión de los adultos vulnerables en la era digital. De esta forma, se pretende contribuir al diseño y a la implementación de modelos holísticos que, utilizando el valor de la tecnología, mejoren la situación de estos segmentos poblacionales bajo la perspectiva que delinea el win-win.

Linguistic Image of Death (LID): The Representation of President Emil Hácha’s Death in the Czech Press of the Period
Authors: Zábranský Lukáš
Published: January 2023

This paper explores the linguistic image of death (LID) of President Emil Hácha in selected Czech newspapers published in June and July 1945 (in Rudé právo and Svobodné slovo). The author verifies certain methods of cognitive linguistics studying the linguistic image of the world in articles thematically related to the passing of this representative of Czech national politics and his funeral. The following aspects are considered to be important: conceptual metaphors, the opposition of I versus the other, and the study of stereotypes and political ethics (conservative versus progressive: the model of the strict father morality versus the model of a caretaker). Before analysing president Hácha's LID, the author tries to place the president's death in a broader context, summarizing characteristic features of LID of imminent Czechoslovak presidents who governed the country in politically critical periods of its history: of T. G. Masaryk and E. Beneš.
Achievable rate as affected by active elements distribution in reconfigurable intelligent surfaces for wireless communication
Authors: Li Dongming , Li Sixu , Wu Guilu , Zhao Chunxi
Published: January 2023

To increase constantly the achievable rate of reconfigurable intelligent surfaces (RISs)-assisted communication systems, the traditional approaches are to deploy a few active elements randomly on the passive RISs. However, the effect of the geometry distribution of the deployment of the active elements is ignored in performance analysis. In this article, three types of geometry distribution with active elements on RISs, denoted as random distribution, uniform distribution, and eight-queens distribution, are discussed to analyze the affect on achievable rate in RISs-assisted wireless communications. Specifically, the optimal achievable rate is obtained according to the predefined codebook, and the codebook is determined by the reflection beamforming codeword related to the active elements geometry distribution in RISs. Simulation results show that different geometry distribution of active elements in RISs causes different influences to achievable rates. The eight-queens distribution proposed in this article for active elements in RISs brings the highest achievable rate compared with random distribution and uniform distribution. In the passive RISs surface, the distribution of a few active elements is limited by the eight-queens, further enhancing the achievable rate of the wireless communication system. This method has a 7% improvement over the conventional method.

Importance

Novel data science and marketing methods of smoking-cessation intervention have not been adequately evaluated.

Objective

To compare machine learning recommender (ML recommender) computer tailoring of motivational text messages vs a standard motivational text–based intervention (standard messaging) and a viral peer-recruitment tool kit (viral tool kit) for recruiting friends and family vs no tool kit in a smoking-cessation intervention.

Design, Setting, and Participants

This 2 ×2 factorial randomized clinical trial with partial allocation, conducted between July 2017 and September 2019 within an online tobacco intervention, recruited current smokers aged 18 years and older who spoke English from the US via the internet and peer referral. Data were analyzed from March through May 2022.

Interventions

Participants registering for the online intervention were randomly assigned to the ML recommender or standard messaging groups followed by partially random allocation to access to viral tool kit or no viral tool kit groups. The ML recommender provided ongoing refinement of message selection based on user feedback and comparison with a growing database of other users, while the standard system selected messages based on participant baseline readiness to quit.

Main Outcomes and Measures

Our primary outcome was self-reported 7-day point prevalence smoking cessation at 6 months.

Results

Of 1487 participants who smoked (444 aged 19-34 years [29.9%], 508 aged 35-54 years [34.1%], 535 aged ≥55 years [36.0%]; 1101 [74.0%] females; 189 Black [12.7%] and 1101 White [78.5%]; 106 Hispanic [7.1%]), 741 individuals were randomly assigned to the ML recommender group and 746 individuals to the standard messaging group; viral tool kit access was provided to 745 participants, and 742 participants received no such access. There was no significant difference in 6-month smoking cessation between ML recommender (146 of 412 participants [35.4%] with outcome data) and standard messaging (156 of 389 participants [40.1%] with outcome data) groups (adjusted odds ratio, 0.81; 95% CI, 0.61-1.08). Smoking cessation was significantly higher in viral tool kit (177 of 395 participants [44.8%] with outcome data) vs no viral tool kit (125 of 406 participants [30.8%] with outcome data) groups (adjusted odds ratio, 1.48; 95% CI, 1.11-1.98).

Conclusions and Relevance

In this study, machine learning–based selection did not improve performance compared with standard message selection, while viral marketing did improve cessation outcomes. These results suggest that in addition to increasing dissemination, viral recruitment may have important implications for improving effectiveness of smoking-cessation interventions.

Filtered multi‐innovation‐based iterative identification methods for multivariate equation‐error ARMA systems
Authors: Sun Shunyuan , Xu Ling , Ding Feng , Sheng Jie
Published: January 2023

This paper focuses on the parameter estimation issues of multivariate equation‐error autoregressive moving average systems. By applying the gradient search and the multi‐innovation theory, we derive a multi‐innovation gradient based iterative (MI‐GI) algorithm. In order to improve the computational efficiency and the parameter estimation accuracy, a filtering and decomposition based gradient iterative (F‐D‐GI) algorithm is presented by using the data filtering technique and the decomposition technique. The key is to choose an appropriate filter to filter the input‐output data and to transform an original system into several subsystems. Compared with the MI‐GI algorithm, the F‐D‐GI algorithm can generate more accurate parameter estimates. Finally, an illustrative example is provided to indicate the effectiveness of the proposed algorithms.

Published: January 2023

Grain boundaries (GBs) are a prolific microstructural feature that dominates the functionality of a wide class of materials. The functionality at a GB results from the unique atomic arrangements, different from those in the grain, that have driven extensive experimental and theoretical studies correlating atomic‐scale GB structures to macroscopic electronic, infrared optical, and thermal properties. In this work, a SrTiO3 GB is examined using atomic‐resolution aberration‐corrected scanning transmission electron microscopy and ultrahigh‐energy‐resolution monochromated electron energy‐loss spectroscopy, in conjunction with density functional theory. This combination enables the correlation of the GB structure, nonstoichiometry, and chemical bonding with a redistribution of vibrational states within the GB dislocation cores. The new experimental access to localized GB vibrations provides a direct route to quantifying the impact of individual boundaries on macroscopic properties.

Haney Soil Health Test changes with season, not subsurface drainage
Authors: Sherbine Kyle , Frankl Aaron , Fernandez Fabian , Pease Lindsay , Cates Anna M.
Published: January 2023

The Haney Soil Health Test (HSHT) is used to quantify soil health using soil biological activity and water‐extractable C and N. However, suitability of the HSHT to measure soil health in subsurface drained fields remains unknown. Our goals were to use the HSHT in Minnesota cropand to (a) test the effect of recent tile drainage installation, (b) evaluate seasonal variability, and (c) calculate a potential N fertilizer credit. Three soil biological indices used in the HSHT were measured seasonally across 2 yr and used to calculate a soil health score and N credit. All metrics were unaffected by subsurface drainage, but all varied seasonally (greatest in spring) and annually (greater in 2020 than in 2021). Soil biological indicators did not change abruptly following subsurface drainage but may change gradually, and this needs to be tested further. Significant seasonal variability may pose challenges in tracking soil health over time.
Moisture changes with increasing summer precipitation in Qilian and Tienshan mountainous areas
Authors: Ma Qianrong , Li Zhongwai , Chen Zhiheng , Su Tao , Wu Yongping , Feng Guolin
Published: January 2023

The precipitation in the Qilian (QMA) and Tienshan (TMA) mountain areas is one of the main sources of subsurface and surface water in northwestern China (NWC). Based on two datasets, CN05.1 and station‐observed daily precipitation, we found that summer precipitation in 1979–2020 exhibited an increasing trend in NWC. The results of rotation empirical orthogonal function (REOF) analysis also separated the increased precipitation patterns in the QMA and TMA from the other REOF modes; the proportion of the precipitation of these areas to the total NWC summer precipitation substantially increased (0.12%⋅year−1 and 0.03%⋅year−1, respectively). According to the moisture budget, the evaporation changes in the QMA and TMA were coherently coupled with precipitation, which suggested the feedback between increasing evaporation and precipitation with the recently warming climate. The precipitation increase was larger than that of evaporation, indicating a net wetting trend in the QMA and TMA. The increase in zonal horizontal and vertical moisture advection terms contributed more to the increased precipitation in the QMA. The increase in meridional moisture advection contributed more to the increased precipitation in the TMA. We concluded comprehensive frameworks of the water vapor transport in climate change in mountain areas in NWC which aimed to contribute to the understanding of arid region hydrology.

Published: January 2023

Individuals with autism spectrum disorder (ASD) may show secondary sensory and cognitive characteristics, including differences in auditory processing, attention, and, according to a prominent hypothesis, the formulation and utilization of predictions. We explored the overlap of audition, attention, and prediction with an online auditory “temporal orienting” task in which participants utilized predictive timing cues (both rhythmic and interval‐based) to improve their detection of faint sounds. We compared an autistic (n = 78) with a nonautistic (n = 83) group, controlling for nonverbal IQ, and used signal detection measures and reaction times to evaluate the effect of valid temporally predictive cues. We hypothesized that temporal orienting would be compromised in autism, but this was not supported by the data: the boost in performance induced by predictability was practically identical for the two groups, except for the small subset of the ASD group with co‐occurring attention deficit hyperactivity disorder, who received less benefit from interval‐based cueing. However, we found that the presence of a rhythm induced a significantly stronger bias toward reporting target detections in the ASD group at large, suggesting weakened response inhibition during rhythmic entrainment.

Der Durchstanznachweis stellt bei der Bemessung von Flachdecken infolge der konzentrierten, punktförmigen Lasteinleitung oftmals den konstruktiv bestimmenden Nachweis dar. Bei unregelmäßigen Deckensystemen oder Belastungen treten zudem ungleichmäßige Schubspannungsverteilungen im Durchstanzbereich auf. In der Tragwerksplanung stellt sich hierbei oft die Frage, wie die ungleichmäßige Schubspannungsverteilung beim Durchstanzen am zweckmäßigsten und mit vertretbarem Aufwand berücksichtigt werden kann. Die direkte Bestimmung der Schubspannungsverteilung in Rundschnitten mittels FE‐Verfahren wird im aktuellen Eurocode 2 nicht explizit ausgeschlossen, aber auch nicht genauer beschrieben. Hier gibt es entsprechenden Freiraum bei der Bemessung für den Tragwerksplaner, aber auch Unklarheiten bei der Interpretation der Ergebnisse. In diesem Beitrag werden FE‐Lösungen zur Bestimmung des Lasterhöhungsfaktors β oder zur direkten Berücksichtigung der ungleichmäßigen Schubspannungsverteilung vorgestellt und anhand eines Anwendungsbeispiels analysiert. Abschließend werden Empfehlungen und Modellierungshinweise zur pragmatischen und möglichst realistischen Bestimmung des Lasterhöhungsfaktors β zur Berücksichtigung von Knotenbiegemomenten gegeben.

Ethoxysanguinarine (ESG) is a benzophenanthridine alkaloid extracted from plants of Papaveraceae family, such as Macleaya cordata (Willd) R. Br. The anti‐cancer activity of ESG has been rarely reported. In this study, we investigated the anti‐breast cancer effect of ESG and its underlying mechanism. MTT assay and flow cytometry analysis showed that ESG inhibited the viability and induced apoptosis in MCF7 and MDA‐MB‐231 human breast cancer cells. Western blot revealed that ESG triggered intrinsic and extrinsic apoptotic pathways, as evidenced by the activation of caspase‐8, caspase‐9 and caspase‐3. ESG attenuated breast cancer cell migration and invasion through Hakai/E‐cadherin/N‐cadherin. Moreover, Hakai knockdown sensitized ESG‐triggered viability and motility inhibition, suggesting that Hakai mediated the anti‐breast cancer effect of ESG. In addition, ESG potentiated the anti‐cancer activity of docetaxel (DTX) in breast cancer cells. Overall, our findings demonstrate that ESG exhibits outstanding pro‐apoptosis and anti‐metastasis effects on breast cancer via a mechanism related to Hakai‐related signaling pathway.
Gender discrimination and career decision‐making difficulties among female Chinese college students: The buffering role of coping styles
Authors: Tian Lu , Hou Zhijin
Published: January 2023

The current study examined the relationship between gender discrimination and a form of career decision‐making difficulties: emotional and personality‐related career decision‐making difficulties among female Chinese college students. It further examined the buffering effect of coping styles on the above relationship. A series of hierarchical regression analyses were conducted on a sample of 1427 female Chinese college students from 19 universities located in different regions in China. Results indicated that only suppressive style of coping served as a buffer on the relationship between gender discrimination and career decision‐making difficulties. Also, gender discrimination, reflective style of coping, and reactive style of coping were positively associated with career decision‐making difficulties. These results supported the need to develop career interventions focusing on discussion of gender discrimination, its impact on one's career decisions, as well as teaching distraction coping strategies in reducing the negative impact of gender discrimination on career decision‐making difficulties among female Chinese college students.

Background

Although age and frailty are associated with worse prognoses for patients who undergo percutaneous coronary intervention (PCI), little is known regarding the independent impact of dementia.

Hypothesis

The aim of this study was to evaluate the association between dementia and outcomes for patients with acute myocardial infarction (AMI).

Methods

Consecutive patients with ST‐elevation or non‐ST elevation MI who had undergone PCI as part of our AMI registry were included in this study. We compared outcomes within the 1‐year period of their PCI, including death and major adverse cardiac events (MACE) and corrected for confounders using Cox regression.

Results

Of 28 274 patients, 9167 patients who had undergone PCI for AMI were included in this study, 250 with dementia; Mean age (77.4 ± 9.4 in the dementia group vs. 63.6 ± 12.7 in the control), female gender (32.4 vs. 24.2%, p = .003), diabetes mellitus (54.0 vs. 42.4%, p < .001) and chronic kidney disease (44.4 vs. 19.3%, p < .001) were higher. At 12 months, unadjusted rates of death (25.5 vs. 9.8%, p < .001) and MACE (33.8 vs. 17.6%, p < .001) were higher for patients with dementia. After standardizing for confounding variables, dementia remained an independent risk factor for death (HR 1.90; CI 1.37–2.65; p < .001) and MACE (HR 1.73; CI 1.30–2.31; p < .001), as well as in propensity score matched analysis (HR 1.54; CI: 1.03–2.28; p < .001 and HR 1.49; CI: 1.09–2.02; p < .001, respectively).

Conclusions

Dementia is an independent predictor of worse outcomes in patients undergoing PCI for AMI. Future intervention and specialized healthcare measures to mitigate this risk is warranted.
Highly accurate blood vessel segmentation using texture‐based modified K‐means clustering with deep learning model
Authors: Lisha L. B. , Helen Sulochana C.
Published: January 2023

This paper suggests a blood vessel segmentation using the Texture‐Based Modified K‐means Clustering (TBMKC) technique to lessen the detrimental effects of light lesions. In the suggested method, the K value is chosen automatically by maximizing the local pixel data of the input image. Utilizing the Gabor Filter and Scale‐Invariant Feature Transform (SIFT), respectively, texture and statistical characteristics are used to extract the local information. The number of pixels present in each class is used to alter the cluster centroid using Particle Swarm Optimization (PSO) methods. Local adaptive thresholding is then used to separate the blood vessel pattern. The proposed method is invariant to scales and rotations due to SIFT features. The thresholding output is given to the modified DCNN (Deep Convolutional Neural Network). Finally, the performance of the (MDCNN+ TBMKC+ PSO) scheme is computed over other extant schemes. The outcomes of the adopted scheme is determined and tested using the retinal image from DRIVE, STARE, HRF, and CHASE_DBI databases. The accuracy of the proposed method is 13.41%, 7.22%, 9.56%, 6.24%, 2.35%, 14.54%, 13.23%, 3.71%, 10.82%, 8.28%, 7.98%, and 54.01% better than the existing method like M‐GAN, MCET‐HHO, CNN, DBN, SVM, RNN, NN, MDCNN+PSO, MDCNN+GA, MCNN+FF, MDCNN+ABC, and MDCNN+LA.

All‐solid‐state batteries with solid ionic conductors packed between solid electrode films can release the dead space between them, enabling a greater number of cells to stack, generating higher voltage to the pack. This Review is focused on using high‐voltage cathode materials, in which the redox peak of the components is extended beyond 4.7 V. Li−Ni−Mn−O systems are currently under investigation for use as the cathode in high‐voltage cells. Solid electrolytes compatible with the cathode, including halide‐ and sulfide‐based electrolytes, are also reviewed. Discussion extends to the compatibility between electrodes and electrolytes at such extended potentials. Moreover, control over the thickness of the anode is essential to reduce solid‐electrolyte interphase formation and growth of dendrites. The Review discusses routes toward optimization of the cell components to minimize electrode‐electrolyte impedance and facilitate ion transportation during the battery cycle.
