Computational Design and Preparation of Cation‐Disordered Oxides for High‐Energy‐Density Li‐Ion Batteries

Cation‐disordered lithium‐excess metal oxides have recently emerged as a promising new class of high‐energy‐density cathode materials for Li‐ion batteries, but the exploration of disordered materials has been hampered by their vast and unexplored composition space. This study proposes a practical methodology for the identification of stable cation‐disordered rocksalts. Here, it is established that the efficient method, which makes use of special quasirandom structures, correctly predicts cation‐ordering strengths in agreement with accurate Monte‐Carlo simulations and experimental observations. By applying the approach to the composition space of ternary oxides with formula unit LiA0.5B0. 5O2 (A, B: transition metals), this study discovers a previously unknown cation‐disordered structure, LiCo0.5Zr0. 5O2, that may function as the basis for a new class of cation‐disordered cathode materials. This computational prediction is confirmed experimentally by solid‐state synthesis and subsequent characterization by powder X‐ray diffraction demonstrating the potential of the computational screening of large composition spaces for accelerating materials discovery.
Ordinary lives behind extraordinary occupations: on the uses of Rubicon for a social history of American intelligence

Abstract This article will evaluate the possible uses of fiction—specifically TV series—for a social history of American intelligence. Drawing on methodological debates within intelligence studies, as well as contemporary philosophy, it argues that certain TV series allow viewers to hypothetically experience the everyday life of ordinary intelligence professionals by permitting in-depth descriptions of specific routines and practices. Such a claim will be illustrated using the example of Rubicon (AMC, 2010), an American TV series that was praised for its realism by professionals and scholars alike. By making visible the ordinary life of professionals (coffee and lunch breaks, daily briefs, interminable waits etc.), Rubicon successfully demystifies the everyday life of intelligence analysts, without normalizing the extraordinary nature of the secret world (secrecy, mistrust, and extreme violence). In addition to challenging the clear-cut and often overly simplistic distinction between the factual and the fictional when it comes to secret intelligence, this contribution will also broaden our understanding of the hidden side of government by shedding light on cultural perceptions (including self-perceptions) of intelligence professionals.

Automatic Classification of Monosyllabic and Multisyllabic Birds Using PDHF

Bioacoustics plays an important role in the conservation of bird species. Bio-acoustic surveys based on autonomous audio recording are both cost-effective and time-efficient. However, there are many bird species with different patterns of vocalization, and it is a challenging task to deal with them. Previous studies have revealed that many authors focus on the segmentation of bird audio without considering specific patterns of bird vocalization. Based on the existing literature, currently there is no work on the segmentation of monosyllabic and multisyllabic birds, separately. Therefore, this research addresses the aforementioned concern and also proposes a collection of audio features named ‘Perceptual, Descriptive, and Harmonic Features (PDHFs)’ that gives promising results in the classification of bird vocalization. Moreover, the classification results improved when monosyllabic and multisyllabic birds were classified separately. To analyze the performance of PDHFs, different classifiers were used in which Artificial neural network (ANN) outperformed other classifiers and demonstrated an accuracy of 98%.
A new control approach for a class of linear switched systems with time-varying delay

In this paper, a new method for designing controller for linear switching systems with varying delay is presented concerning the Hurwitz-Convex combination. For stability analysis the Lyapunov-Krasovskii function is used. The stability analysis results are given based on the linear matrix inequalities (LMIs), and it is possible to obtain upper delay bound that guarantees the stability of system by solving the linear matrix inequalities. Compared with the other methods, the proposed controller can be used to get a less conservative criterion and ensures the stability of linear switching systems with time-varying delay in which delay has way larger upper bound in comparison with the delay bounds that are considered in other methods. Numerical examples are given to demonstrate the effectiveness of proposed method.
Analysis of the Head of a Simulation Crash Test Dummy with Speed Motion

The article presents a model of an anthropometric dummy designed for low velocity crash tests, designed in ADAMS. The model consists of rigid bodies connected with special joints with appropriately selected stiffness and damping. The simulation dummy has the appropriate dimensions, shape, and mass of individual elements to suit a 50 percentile male. The purpose of this article is to draw attention to low speed crash tests. Current dummies such as THOR and Hybrid III are used for crash tests at speeds above 40 km/h. In contrast, the low-speed test dummy currently used is the BioRID-II dummy, which is mainly adapted to the whiplash test at speeds of up to 16km/h. Thus, it can be seen that there is a gap in the use of crash test dummies. There are no low-speed dummies for side and front crash tests, and there are no dummies for rear crash tests between 16 km/h and 25 km/h. Which corresponds to a collision of a passenger vehicle with a hard obstacle at a speed of 30 km/h. Therefore, in collisions with low speeds of 20 km/h, the splash airbag will probably not be activated. The article contains the results of a computer simulation at a speed of 20 km/h vehicle out in the ADAMS program. These results were compared with the experimental results of the laboratory crash test using volunteers and the Hybrid III dummy. The simulation results are the basis for building the physical model dummy. The simulation aims to reflect the greatest possible compliance of the movements of individual parts of the human body during a collision at low speed.
Phytochemical Screening and In Vitro Antioxidant and Anti-inflammatory Activities of Aerial Parts of Euphorbia hirta L.

Euphorbia hirta L (Euphorbiaceae) also called asthma herb has long been prescribed in traditional medicine because it exhibits diverse pharmacological actions due to the presence of alkaloids, flavonoids, polyphenols, triterpenoids, and saponins. The present study is aimed at the study of phytochemical and antioxidant activity and anti-inflammatory screening of E. hirta. Extraction of dried powder was performed followed by phytochemical screening using color reactions. Total phenolic content (TPC) and total flavonoid content (TFC) of the extracts were estimated by Folin-Ciocalteu and Aluminum chloride method respectively. The antioxidant activity was studied by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method. Anti-inflammatory activity was studied by using protein denaturation in vitro bioassay. Phytochemical screening showed the presence of flavonoids, alkaloids, and phenolic compounds. TPC, TFC and antioxidant activity (IC50) of the extract were found as 288.10 mg gallic acid equivalent per gram (GAE/g), 29.36 mg quercetin equivalent per gram (QE/g) and 32.23 µg/mL (p<0.05) respectively. Diclofenac sodium and E. hirta extract showed the maximum inhibition of 91.28% and 68.20% respectively at the concentration of 1000 µg/mL compared with control (p>0.05). The phenolic compounds and flavonoids exert antioxidant and anti-inflammatory activities because of their scavenging ability. The demonstrated antioxidant and anti-inflammatory activities may be the rationale behind some of its folkloric uses and also may be responsible for some of its pharmacological effects. Thus, E. hirta can be considered a good source of antioxidants and anti-inflammatory actions, which might be beneficial for combating oxidative stress.
Use of Dynamic Mechanical Analysis (DMA) for Characterizing Interfacial Interactions in Filled Polymers

Dynamic mechanical analysis (DMA) provides reliable information about the viscoelastic behavior of neat and filled polymers. The properties of filled polymers are relevant to different industries as protective organic coatings, composites etc. Interfacial interactions in filled polymers play an important role in determining their bulk properties and performance during service life. In this brief review article, studies that used DMA to characterize the interfacial interactions in filled polymers have been reviewed. The available open literature provides a mixed opinion about the influence of interfacial interactions on the glass transition temperature of filled polymers. Nevertheless, it appears that in the case of strong interfacial interactions between the filler particles and the polymeric matrix, the peak value of tan δ is reduced in comparison to that of a filled polymer where these interactions are weak.
The Effect of an Education Intervention on Mental Health Literacy among Middle School Female Students

Background and Objective: Enhancing the mental health literacy(MHL) through school-based education intervention may encourage mental health promotion, prevention, and care and reduce stigma in adolescents. The present study aimed to determine the eﬀect of educational intervention on MHL among middle school female students in Mashhad. Materials and Methods: A quasi-experimental study was carried out on 140 female students aged between 13-15 years from two governmental middle schools in 2019 Mashhad, Iran. A multistage sampling method was used. First, one education area was randomly selected andtwo middle schools were randomly selected from this area. One middle school was considered as intervention setting and the other middle school considered as control setting. Atotal of 70 students were randomly selected from each school and allocated into two intervention and control group. Mental Health Literacy Scale (MHLS) was used to estimate MHL among student in two stages (before and after intervention). The intervention group were received four training sessions (90 minutes) based on MHL concept. Descriptive, Paired t-test, independent sample t-test and Chi-square test were used to analyze the data using spss21 software. Results: Before the intervention, the two groups had no significant difference in the mean score of MHL (P>0.05). After the intervention, the mean score of MHL increased from 10.5±1.34 to 17.27±11.33 in the intervention group which was statistically significant (P<0.001). Conclusion: Designing and implementing educational interventions can promote MHL of middle school female students.
Investments in Nascent Project-Based Enterprises: The interplay between role-congruent reputations and institutional endorsement

We study nascent project-based enterprises (PBEs) through the lens of upper echelons and institutional theory. We analyse the interplay between the different role-congruent reputations of their project entrepreneurs and the institutional endorsement of their project idea, theorizing how these affect PBEs’ ability to attract private investments. In the context of the Italian film industry, we find that the commercial reputation of the project entrepreneur in the producer role is crucial for attracting investors, while the artistic reputation of the project entrepreneur in the creative director role is crucial for attaining institutional endorsement of the project idea. Finally, we find that the effect of the commercial reputation of the project entrepreneur in the producer role on attracting investments is mediated by the institutional endorsement. We contribute to the literature on PBEs by demonstrating how specific combinations of project entrepreneurs’ roles and (role-congruent) reputations can directly and indirectly attract investments.
Strategies for the viability of rechargeable lithium-sulfur batteries

Purpose: Lithium-sulfur (Li-S) batteries are considered as one of the most promising next-generation rechargeable batteries for electrical energy storage because of their high theoretical specific energy of ~ 2500 Wh kg-1, low production cost, and high abundance of sulfur. However, the high charge-storage capacity of sulfur cannot be effectively utilized due to the insulating nature of the active material and the easy migration of polysulfide intermediates from the cathode to the anode. In this research article, we describe a concise summary of two successful methods for solving the scientific problems and improving the Li-S cell performances. Design/methodology/approach: Successful strategies in addressing the scientific and engineering issues of Li-S cells can be divided into two major categories: (i) sulfur-based nanocomposites that improve the Li-S cell performance based on the cathode active material and (ii) cell configuration modifications that enhance the Li-S cell performance by adopting the materials nature of sulfur. Findings: Current technologies including nanocomposite development and cell configuration design have greatly ameliorated the overall electrochemical performance of Li-S batteries by improving the electrochemical utilization of sulfur and the retention rate of polysulfides. Research limitations/implications: The overcome the challenges of Li-S batteries, a fair balance has to be taken between (i) sulfur loading/content and cell performances, (ii) amount of active material and porosity of the matrix, and (iii) added weight from the modified cell components and energy density of the custom Li-S cells. Practical implications: The next step for the reality of commercial Li-S batteries might be (i) development of high-loading sulfur cathodes, (ii) anode configuration modification, and (iii) design of electrochemically stable electrolytes. Originality/value: A concise introduction of the development of the sulfur core in Li-S cells is provided.
International Chamber of Commerce Rules for Trade Terms - The Terminological Approach

Purpose: The rules of International Commercial Terms (Incoterms) define the important element of the international sales contract, the so-called parity. The parity means the place, where the cost and risks are handed over from the seller to the buyer. In this paper, we would like to answer to following questions: What are the principles of the terminological system of Incoterms editions following each other? What is the difference between the logic of the creators of terminology and its users? How does change the relationship of users and International Chamber of Commerce (ICC) in the mirror of terminological changes? Approach/Methodology/Design: We demonstrate and analyze the modifications of Incoterms rules updated in the last 40 years focusing on the development of theory and practice of trade terminology. Terminological theoretical frame is used in this paper. Findings: The Incoterms were based in the first phase on historical principle, in the second phase on logical principle, in the third phase on functional principle. The creators of terminology must build a structure based on strict logic, eliminating the historical perspective, not making a difference between the original old and the artificially created new ones. The users preferred the old ones, building a structure using them to create a terminological structure. The ICC for a long time intended to force its own system in prescriptive method, but from the 2010 edition, it has concluded a compromise accepting the logic of everyday usage based on tradition in the 2020 edition. Practical Implications: The paper gives a short overview of the rules of international trade from a terminological point of view. Originality/Value: The changes of Incoterms have been investigated from legal, risk management, and logistical points of view but there is still now a gap in the research of Incoterms concerning the terminological perspective. Terminological analysis with its new instruments and view can reveal the principles of building the terminology, can mirror the changes of the power shifting.
4-Thiazolidinone derivatives: synthesis, antimicrobial, anticancer evaluation and QSAR studies

A series of 4-thiazolidinone derivatives (1–18) was synthesized and tested in vitro for its antimicrobial and anticancer potential. Synthesized compounds were found to be 5 more potent antimicrobial agents than anticancer agents. Anticancer screening results indicated that compound 13 (IC50 = 15.18 μM) was the most active anticancer agent and was more potent than the standard drug, carboplatin (IC50 > 100 μM). Antimicrobial activity results indicated that 14 was the most active antimicrobial agent (pMICec = 2.14 μM) and may serve as an important lead for the discovery of novel antimicrobial agents. The QSAR studies indicated that the antibacterial and antifungal activities of the synthesized derivatives against different microbial strains were governed by lipophilic parameter, log P, topological parameter, κα3 and electronic parameters cos E and Nu. E.
Ozone production in parallel multichannel dielectric barrier discharge from oxygen and air: the influence of gas pressure

This research aims to investigate the influence of gas pressure (0.1 Mpa–0.2 Mpa) on ozone generation in a parallel multichannel dielectric barrier discharge (DBD) reactor with a narrow gap (0.2 mm). In addition to determining ozone concentration and ozone yield characteristics with gas pressure variation, this paper examines the possible reasons leading to the inconsistency with previous reported results. All the experimental results are plotted on the basis of specific input energy (SIE) in order to conduct the comparison within identical power density. By reviewing the experimental results, the possible cause leading to the inconsistency concerning gas pressure dependences of ozone generation was found using different comparison bases. Results show that ozone generation is slightly suppressed with an increase of gas pressure with an initial increase in SIE. The results of the ozone yield show that an increase of gas pressure would have a favorable effect on ozone production efficiency with an SIE larger than 400 J l−1 in oxygen while ozone yield reaches the maximum at 0.14 Mpa with an SIE larger than 150 J l−1 in air. Increasing gas pressure would lead to a higher critical SIE value at which ozone yield firstly decreases with an increase of SIE both in oxygen and air. The results of nitrogen oxide byproducts show that both NOx byproducts emission and the discharge poisoning effect are suppressed by increasing gas pressure in air plasmas.
Vibrational playbacks and microscopy to study the signalling behaviour and female physiology of Philaenus spumarius

The meadow spittlebug Philaenus spumarius, vector of the bacterium Xylella fastidiosa, relies on vibrational communication to accomplish mating: the female calls to establish a duet with a male. A deeper knowledge of the species’ reproductive biology and behaviour would provide useful information for developing control techniques based on principles of ‘biotremology’, which studies the vibrational behaviour of animals. Playback tests were conducted on single females and male–female pairs of P. spumarius from June to October 2018, and the features of the recorded calling signals were analysed using a wavelet decomposition. Dissections were performed on females to evaluate the relationship between calling activity and ovarioles development. From August onwards, females started to emit calling signals and to develop ovarioles. Female calling activity, duration of their chirps and their responsiveness to mating increased as the season progressed, and they were correlated with ovarioles’ development and presence of mature eggs. Hence, the ovarian maturation represents a key factor in association with the development of the sexual behaviour of P. spumarius females. Conversely, males produced advertisement signals soon after adult eclosion in May, but these signals were not involved in the pair formation process. Mating was achieved only when males produced courtship signals in response to female calling signals and established with them vibrational duets starting from August. Here, we provide new information regarding the P. spumarius’ ethology and hypothesize that potential mating disruption techniques should consider the insect physiology and be applied when both sexes are responsive to mating signals.
Serum albumin predicts hyperuricemia in patients with idiopathic membranous nephropathy.

AIM The aim of the study was to examine the cross-sectional association between serum albumin and hyperuricemia (HU). MATERIALS AND METHODS HU was defined as uric acid ≥ 420 umol/L for the male population and ≥ 357 umol/L for the female population. We reviewed the files of 216 consecutive patients with idiopathic membranous nephropathy treated at our hospital between 2010 and 2019. The correlation of serum albumin with hyperuricemia and the association between serum uric acid levels and the clinical of Idiopathic membranous nephropathy were assessed by statistical analysis. A multivariable logistic analysis model was applied to test the association after adjusting for a number of potential confounding factors. RESULTS Triglyceride and serum albumin were higher in the group with hyperuricemia than in the group without hyperuricemia (p = 0.020, p < 0.001, respectively). As serum albumin rose to 1 g/L, the probability for hyperuricemia increased to 17% (adjusted II OR = 1.17, 95% CI (1.02, 1.35), p = 0.0294). A unit increase in serum albumin was associated with an increase of 6.64 g/L in uric acid (adjusted II β = 6.64, p = 0.0135). Using tertile 1 (T1) for reference, the tertile 3 (T3) group was positively associated with both hyperuricemia (adjusted II OR = 44.21, 95% CI (12.76, 75.67), p = 0.0064) and uric acid (adjusted II β = 98.64, p = 0.0116). The interaction test showed significant interactions between serum albumin and the body mass index (BMI) when hyperuricemia or uric acid were used to determine the outcomes. The participants with a BMI ≥ 25 kg/m2 had a higher OR between serum albumin and hyperuricemia and had a higher β between serum albumin and uric acid than those with a BMI < 25kg/m2 (for hyperuricemia: OR = 1.01 vs. 1.18, p for interaction = 0.0056; for uric acid: β = 0.96 vs. 6.23, p for interaction = 0.0154). The area under the ROC curve (AUC) was 0.7615 in the participants with a BMI ≥ 25 kg/m2. The sensitivity and specificity of this point were 47.37% and 95.83%, respectively. CONCLUSION Our study showed that serum albumin was positively associated with hyperuricemia and uric acid, especially in obese subjects.
