What Makes a Good Diversity Manager?
Authors: Köllen Thomas ,   Philosophy Documentation Center
Published: June 2022

The prevalent rule-based perspective on diversity management renders most diversity initiatives more or less uniform, and it therefore also renders the individual(s) in charge of these initiatives replaceable. Against this background, this article argues that an ethical realignment towards a virtue-based perspective, focusing on the diversity manager him- or herself, could help rethink diversity management, and to refashion it into a more impactful shape. The virtue in question is the Aristotelian notion of the virtue of practical wisdom (phrónēsis). Making their practical wisdom a selection criterion for the recruitment process is a first step in the direction of upgrading the concept of diversity management. However, it is also important to adjust their working conditions, the design of their role, as well as their autonomy and performance evaluations in a way that allows them to develop, maintain, and practice this phrónēsis.
La memoria sensible según san Agustín de Hipona. Una aportación a la psicología
Authors: Marchán Wilfredo ,   Order of Augustinian Recollects
Published: June 2022

St. Augustine, through his most recognized philosophical writings, has elaborated a thesis where he makes known the concept, function and laws of the sensitive memory as the indispensable faculty for the intellectual and personal development. The main philosophical works of the Christian author “Confessions” and “Of the Trinity” seek to meditate and deepen the phenomenon of memory in order to unravel the faculty of remembering present in human beings and animals. In his confessions, St. Augustine shapes the events that have marked his life before, during and after his conversion to Christianity, where he manifests the emotions, causes and consequences. In psychology, memory is part of his fields of study in order to explain, through the scientific method, the process of memory and its relationship with behavioral and psychic phenomena of man. The first authors of psychology, have proposed various theories and schemes that allow to observe and give a diagnosis to the behaviors that the person manifests, to these phenomena is involved the sensitive memory as responsible for such attitudes. St. Augustine has taken the first steps on the study of the sensitive memory from the rational, speculative and Christian scope; therefore, it becomes one of the great contributions on the study of the nemetic phenomenon and to be considered as the father of psychology.

Musical Theatricalization in the aspect of value communication: on the issue of terminology
Authors: Kireyeva Natalia Yurievna
Published: June 2022

The object of study is musical theatricalization, which is considered from the perspective of value communication. The novelty of the research lies in the theoretical development and introduction into scientific circulation of the generalizing concept of musical theatricalization, which allows combining genre dominants of various aesthetic activities in its field. The concept of musical theatricalization is appropriate and helps to cover all the available variety of musical and theatrical material without being constrained by historical and specifically professional frameworks. Musical theatricalization is based on musical and theatrical creativity as a conscious synthetic (in art) or unconscious syncretic (in folklore) form of expression of a multidimensional human potential. Musical theatricalization includes various forms of musical and theatrical performances and musical and theatrical genres formed during their evolution. Musical theatricalization acts as a genre class in which there are stable and mobile genre features. The musical and theatrical beginnings become axial, which can manifest themselves in different forms, changing the ratio of musical and theatrical means of expression. There is a movement of the theatrical component: from the minimal manifestation of theatricality in a musical work (the inclusion of kinesthetic means of expression) to the stage production of an opera performance and even a mystery. The study of musical theatricalization is carried out from the position of functional relativity, which allows us to determine the degree of importance of the phenomenon of art for individual subjects who are in a communicative situation. The same work can have different degrees of value depending on the historical and communicative context and, accordingly, on the functions that a particular work acquires. The aesthetic and anthropological value of a piece of music is determined by the functional mood of the addressee at a certain moment. The discrepancy between the functional mood of the participants of the communicative act for various reasons leads to a loss of the quality of communication and, as a consequence, to discrepancies in the evaluation of the artwork, the emergence of functional asymmetry.
Actual problems of legal provision of information security of the Russian Federation
Authors: Veprentseva Tatiana Alekseevna
Published: June 2022

The subject of this article is the normative legal acts of the Russian Federation in the field of information security, as well as the theoretical positions of modern researchers on the legal provision of information security in the Russian Federation. The modern legislation of the Russian Federation on information security issues is analyzed in detail, while special attention is paid to the consideration of regulatory legal acts that ensure Internet governance, which is one of the most important areas of development of legislation in this area. The most important aspects of information security that attract research interest, approaches to solving existing problems in this area are identified. The analysis of the norms of information legislation and the systematization of the material is based on the formal-logical method. The comparative legal method allowed us to identify current trends in the development of legislation in this area, and the prognostic method allowed us to determine the prospects for the development of legislation aimed at creating a system of effective legal provision of information security in the Russian Federation. The article presents the author's reasoned position on the problems of legal provision of information security and the prospects for their solution in the current international situation. The conclusions obtained as a result of the study allow us to speak about the prematurity of codification of legislation in the field of information security, at the same time, the need for systematic movement in a given direction. Conclusions are drawn that today the Russian Federation continues to pursue a policy in the field of information security, which defends the sovereign information space, and also initiates the activity of the world community aimed at creating effective mechanisms for ensuring international information security through the activities of international organizations and expanding the coverage of international law.

Published: June 2022

The subject of the study is the system of relations arising in ensuring the environmental safety of modern Russia in the field of waste processing of solid industrial and household waste. The object of the study is the regional economy of the Volgograd region, where there are significant opportunities for the creation and development of incineration facilities. The authors consider in detail such aspects of the topic as: analysis of the development of the incineration business in the global economy; justification of the potential of the incineration business in modern Russia; analysis of the practice of creating waste disposal facilities in domestic conditions; justification of the construction of incineration plants in the Volgograd region. Special attention is paid to the economic justification of the efficiency of incineration plants in the Volgograd region. The main conclusions of the study are the following: waste disposal is currently a very promising area of business development, a powerful aspect of the growth of the regional economy of some subjects of the Russian Federation; international experience shows that a very powerful economic potential is already involved in this area, especially in the most developed countries of the global economy; the modern market offers a wide range of technical and managerialcommercial funds for the development of waste disposal enterprises; in many regions of Russia there is high business activity for the development of waste disposal enterprises, but this activity encounters environmental restrictions and inertia on the part of environmental organizations; creating conditions for the development of waste recycling facilities in the Volgograd region will have a high economic effect and will have a positive impact on the overall socio-economiceconomic development of the region. A special contribution of the authors to the study of the topic is its actualization and attraction of rich world experience. The novelty of the research lies in the adaptation of the research topic to the practical conditions of the Volgograd region and other regions of Russia.
Signs of individual judicial regulation in criminal proceedings and its definition
Authors: Kripinevich Svetlana Sergeevna
Published: June 2022

Criminal proceedings are the sphere of mandatory regulation. However, its development and modern achievements of the entire legal science as a whole make it possible to make relevant clarifications to its content (legislation and activities). The purpose of the work is to identify the most significant features of individual judicial regulation in the field of criminal proceedings and offer them to the general scientific community for discussion. The main subject of this study was the theoretical concept of "individual judicial regulation" and its features in criminal proceedings. In criminal proceedings to date, such studies have been fragmentary, whereas in the theory of law, civil sciences, this area is represented by large-scale and fundamental works. It seems that the scale of the research and its long history should be realized not only in civil proceedings, civil and administrative law, but also in criminal proceedings. One of the first in this series should be the definition of the concept of "individual judicial regulation in criminal proceedings".   In the course of the research, traditional scientific methodology was used: including general scientific methods (dialectics, analysis, synthesis, generalization, etc.), as well as private scientific methods - comparative legal and formal legal. The applied methods of scientific research allowed us to gain new knowledge concerning the essential features of individual judicial regulation and their use in defining this concept. The result was the author's definition of individual judicial regulation in criminal proceedings. The application of the results is possible in the field of ongoing scientific research, in terms of improving criminal procedure legislation and the practice of its application. The main conclusion of the author is the need to introduce the concept of individual judicial regulation into criminal proceedings at the level of its theoretical provisions and into the legislative framework.
Traffic Volume Forecasting Model of Freeway Toll Stations During Holidays – An SVM Model
Authors: HU Xiaowei , XIAO Yongzhi , WANG Tianlin , YANG Lu , TANG Pengcheng
Published: June 2022

Support vector machine (SVM) models have good performance in predicting daily traffic volume at toll stations, however, they cannot accurately predict holiday traffic volume. Therefore, an improved SVM model is proposed in this paper. The paper takes a toll station in Heilongjiang, China as an example, and uses the daily traffic volume as the learning set. The current day traffic volume is used as the dependent variable and the previous 7-day traffic volume is used as the independent variable for model learning. This paper found that the basic SVM model is not accurate enough to forecast the traffic volume during holidays. To improve the model accuracy, this paper first used the SVM model to forecast non-holiday traffic volumes, and proposed a prediction method using quarterly conversion coefficients combined with the SVM model to construct an improved SVM model. The result of the prediction showed that the improved SVM model in this paper was able to effectively improve accuracy, making it better than in the basic SVM and GBDT model, thus proving the feasibility of the improved SVM model.
Microplastics do not affect bleaching of Acropora cervicornis at ambient or elevated temperatures
Authors: Plafcan Martina M. , Stallings Christopher D.
Published: June 2022

Microplastic pollution can harm organisms and ecosystems such as coral reefs. Corals are important habitat-forming organisms that are sensitive to environmental conditions and have been declining due to stressors associated with climate change. Despite their ecological importance, it is unclear how corals may be affected by microplastics or if there are synergistic effects with rising ocean temperatures. To address this research gap, we experimentally examined the combined effects of environmentally relevant microplastic concentrations (i.e., the global average) and elevated temperatures on bleaching of the threatened Caribbean coral, Acropora cervicornis. In a controlled laboratory setting, we exposed coral fragments to orthogonally crossed treatment levels of low-density polyethylene microplastic beads (0 and 11.8 particles L−1) and water temperatures (ambient at 28 °C and elevated at 32 °C). Zooxanthellae densities were quantified after the 17-day experiment to measure the bleaching response. Regardless of microplastic treatment level, corals in the elevated temperature treatment were visibly bleached and necrotic (i.e., significant negative effect on zooxanthellae density) while those exposed to ambient temperature remained healthy. Thus, our study successfully elicited the expected bleaching response to a high-water temperature. However, we did not observe significant effects of microplastics at either individual (ambient temperature) or combined levels (elevated temperature). Although elevated temperatures remain a larger threat to corals, responses to microplastics are complex and may vary based on focal organisms or on plastic conditions (e.g., concentration, size, shape). Our findings add to a small but growing body of research on the effects of microplastics on corals, but further work is warranted in this emerging field to fully understand how sensitive ecosystems are affected by this pollutant.
Parvovirus Infection Causing Aplastic Anaemia in an Immunocompetent Patient Diagnosed by Bone Marrow Aspiration Cytology
Authors: Giri Ranjana , Senapati Urmila
Published: June 2022

Human Parvovirus infection is associated with transient aplastic crisis as a most common complication in chronic haemolytic anaemia patients. Very few case reports are available regarding aplastic crisis in immunocompetent patients. Here the authors are reporting a case of 17-year-old immunocompetent male that presented with fever, headache for three days. Complete blood count showed pancytopenia. Bone marrow aspiration and trephine biopsy revealed hypocellularity. Giant pro-erythroblasts with multiple cytoplasmic projections (dog ear appearance) and prominent intranuclear inclusions were seen in marrow aspirated cytology. Classical cytological findings in bone marrow aspiration raised the suspicion of human parvovirus infection. Findings were confirmed by positive Deoxyribonucleic Acid Polymerase Chain Reaction (DNA PCR) for parvovirus B19 and parvovirus Immunoglobulin M (IgM) antibody using Enzyme Linked Immunosorbent Assay (ELISA) test. Patient was managed with antibiotic therapy and was trasfused three units of blood. Complete blood count became normal after two months. This emphasises the role of keeping high index of suspicious for Parvovirus B19 infection as a cause of aplastic anaemia even in individual without underlying diseases. Secondly characteristic morphological changes in the erythroid precursors in the bone marrow aspiration is highly suggestive of Parvovirus B19 infection.

Authors: Sakpal Rahul Y , Warpe Bhushan M , Joshi-Warpe Shweta
Published: June 2022

Introduction: Oral cavity is a common site for many types of benign, precancerous conditions and malignant tumours as well as development of congenital and acquired lesions. Oral cancers are the most common type of cancer in Indian men and actually accounted for 40% of all forms of cancers due to tobacco addiction, representing 4% of total body cancers. In Indian females, 2% of all cancers are of oral cavity. The knowledge of aetiological factors for the development of oral cancers can make the disease preventable. Aim: To study histopathological spectrum of various oral lesions. Materials and Methods: This was a prospective observational study done, during the period from November 2013 to June 2017, 150 cases of oral lesions were studied at a tertiary care hospital in Miraj. All the cases were studied and histopathological diagnosis was correlated with clinical findings. The Microsoft Excel 2010 sheet was filled as per case proforma of patients. Analysis was done manually like age wise, gender wise, site wise and sex wise distribution based on the Excel sheet data. Results: The age of study population ranged from 6-80 years. Most oral cavity lesions were found in the age group 51-60 years of age group with 46/150 (30.67%) cases. Male to female ratio was 1.78:1. Malignant epithelial tumours of oral cavity comprised 100/150 cases (66.67% cases). Amongst malignant tumours, Squamous Cell Carcinoma (SCC) comprised 92/100 cases (92% cases). There was history of addiction in 96/100 cases (96% cases) with 52/100 cases as tobacco chewers (52% cases). 4/100 cases did not have history of addiction (4% cases). Conclusion: The clinical examination of the oral pathological lesions does not lead to appropriate diagnosis. The clinical diagnosis must be supplemented by ‘gold standard’ histopathological examination for confirming the malignant tendency of oral lesions.

Published: June 2022

Introduction: Cervical cancer is the leading cancer in Indian women. Mast cell distribution and density support a diagnosis in addition to routine histopathological examination. Aim: To study the variation of mast cell distribution and density in different uterine cervical lesions. Materials and Methods: A total of 352 cases of cervical lesions were studied cross-sectionally from June 2018 to May 2020, in the Department of Pathology, Subharti Medical College, and associated Chhatrapati Shivaji Hospital, Meerut, Uttar Pradesh, India. These included both hysterectomy (296 cases) and cervical (56 cases) biopsies. Routine histopathological examination was done with Haematoxylin and Eosin stain (H&E) to categorise the lesions into non-neoplastic and Neoplastic lesions. For identification of mast cells 1% toluidine blue stain was applied to evaluate mast cell distribution and density. Data analysis was done using analysis of variance (ANOVA): one-way t-test was applied. A p-value of ≤0.05 was taken as significant. R-Software was used for analysis of data. Results: Out of 352 cases, 302 (85.7%) were non-Neoplastic and 14% 48 (13.6%) were neoplastic. Two cases were of unremarkable pathology. Chronic cervicitis was observed as the most common lesion 293 (97%) out of 302 cases. Age of the patients ranged from 21-78 years. Most of the patients were in the reproductive age group: 21-49 years of age 274 (77.8%) cases. Mean mast cell count decreased from premalignant cases to malignant cases. In case of cervical intraepithelial lesion, mean mast cell count was found to be 26.5/10 High Per Field (HPF) and in cases of malignancy mean mast cell count of 17.5/10 HPF was observed. Mean mast cell count showed an inverse relationship with the grade of dysplasia and from dysplasia to cases of malignancy. Conclusion: Mast cell distribution and density support a diagnosis in addition to the routine histopathology, especially in cases of small cervical biopsies which are difficult to interpret.

Authors: Prasad Chitta Ranjan , Toppo Anupa , Sharma Yespal
Published: June 2022

Introduction: The plasma collected from the recovered Coronavirus Disease 2019 (COVID-19) patients is used therapeutically in serious COVID-19 patients as a life saving procedure. Serum Immunoglobulin G (IgG) estimation is a routine procedure followed in these voluntary donors. In this routine procedure, authors have come across patients with particular blood group having more chances of seronegativity for COVID-19 IgG antibody. This is the reason why the present study was conducted. Aim: To find out the variable IgG response in recovered COVID- 19 patients with different types of clinical manifestations along with the possible relation with different types of blood groups of ABO system. Materials and Methods: This retrospective study was conducted in plasma bank of Veer Surendra Sai Institute of Medical Science and Research, Burla, Odisha, India, from 1st August to 15th December 2020. Severe Acute Respiratory Syndrome Coronavirus-2 (SARS- CoV-2) specific IgG antibody level was estimated quantitatively using Chemiluminescence Immunoassay (CLIA) method. Patients with IgG level more than 1.4 were taken as positive. Results: This study had estimated IgG level during screening of 440 voluntary plasma donors. Out of these, seropositivity was found in 354 patients. Patients with blood group O and AB were having seropositivity rate more than that of other ABO blood groups, whereas seronegativity percentage was more in blood group A patients. Conclusion: There was a non specific relation between severity of symptoms and detectable development of IgG antibody in recovered corona patients. Also, blood group A patients develop less likely IgG antibody against COVID-19.
Impact of Cosmobiological Factors on Chromosomal Anomalies Rates - Ethical Consideration
Authors: Serapinas Danielius , Narbekovas Andrius
Published: June 2022

Backround: In recent years, there is an increasing number of data supporting the relation between lunar cycle and alterations in human body. For instance, it has been proved that hospitalized spontaneous abortions are significantly associated with the lunar cycle . Given that the most common cause of spontaneous abortion is chromosomal abnormalities of the embryo, we presumed that the lunar cycle could influence the occurrence of chromosomal diseases. From the point of bioethics it is a question if it is applicable to talk with patients about possible impact of cosmobiological factors on their case of chromosomal anomaly.

Patients and Methods: We have selected 52 patients, who were bearing a fetus with a prenatally diagnosed chromosomal disorder, which included Down, Turner, Klinefelter, Patau and Edward syndromes. The control group (n=92) consisted of families, that were prenatally tested for chromosomal abnormalities and the results were negative. Then we gathered and analyzed information from patients' medical histories about various factors, which could have predisposed chromosomal disorders: age of both progenitors, consumption of medications during pregnancy, number of miscarriages, number of abortions, cases of genetic disorders in relatives, lunar phase on the day of conception.

Results: Lunar phases at the time of conception in the test group distributed as following: new Moon 32.7 percent, first quarter 25.0 percent, full Moon 28.8 percent, third quarter 13.5 percent. In the control group lunar phases distributed as following: new Moon 29.3 percent, first quarter 27.2 percent, full Moon 26.1 percent, third quarter 17.4 percent. There was observed no statistically significant difference between test and control groups (p>0.05). OR for conception with chromosomal anomalies were increased in July (2.7(CI 95% 1.5-4.9) and December (3.2 (CI 95% 1.5-5.2) (p<0.05). OR showed decreased risk for chromosomal anomalies during conception at January (0.3 (CI 95% 0.1-0.7) , April (0.5 (CI 95% 0.2-0.7) and June 0.5 (CI 95% 0.2-0.8) (p<0.05).

Conclusions: Our study showed there were no associations between lunar phase at the time of conception with the rates of chromosomal mutations. Conception in July and December increases the risk of chromosomal anomalies during conception. In contrast conception in January, April and June decreases chromosomal anomalies rates.

Authors: Kimura Masahiro , Harata Koshiro , Tsuboi Ken , Maeda Yuzo , Nakaya Seiichi , Matsuo Yoichi , Mitsui Akira , Takiguchi Shuji
Published: June 2022

Background: One of the complications of endoscopic surgery is port-site hernia. The risk of port-site hernia is minimized by proper port-site closure, which relies on appropriate characterization of the fascia, particularly the direction of fascial fissures.

Methods: The following 4 procedures were examined to identify the fascial fissure direction: mobility of the port, observation from the lumen of the port, palpation for fascia, and visual confirmation. The match rate of each procedure with visual confirmation was verified.

Results: 51 port-sites without fasciotomy were examined. The direction of the fissure was from 12 to 6 o’clock in 11 cases and 3 to 9 o’clock in 40 cases. The match rate between mobility and the fissure was 45.1%. The match rate of observation from the lumen was 96.1%. Comparing the suturing time, the average time was significantly shortened to 327 seconds in the second half compared to 494 seconds in the first half of our study period with the VersaOneTM fascial closure system.

Conclusion: Treatment of port-site hernia can be done by suture or mesh repair, although ideally it is best to prevent the hernia in the first place. The fissure direction was almost always identifiable via observation from the lumen of the port. Closure of the port-site using modified Z-sutures allowed for full fascial closure, particularly in cases of patients with obesity.

Adaptive multi‐dimensional Taylor network tracking control for nonlinear systems with input saturation and full state time‐varying constraints
Authors: Han Yu‐Qun , Liu Si‐Min , Du Yang , Yang Shu‐Guo
Published: June 2022

In this article, an adaptive multi‐dimensional Taylor network (MTN) control approach is developed for nonlinear systems subject to input saturation and full state time‐varying constraints. Using the function approximation property of MTN, an adaptive tracking control method is developed by incorporating the concept of time‐varying state constraints into the construct of barrier Lyapunov functions. The proposed approach not only ensures all closed‐loop system signals are bounded but also that all states of the system never violate the given time‐varying constraints. The most important advantage of the proposed control strategy is that it can obtain satisfactory control effects with low computational cost. Finally, two examples are given to validate the effectiveness of the proposed method.
NN‐based decentralized adaptive event‐triggered control for nonlinear interconnected systems under intermittent DoS and injection attacks
Authors: Cui Yahui , Sun Haibin , Hou Linlin
Published: June 2022

This article investigates the problem of decentralized adaptive neural network event‐triggered control of strict feedback nonlinear interconnected systems suffering injection attacks and intermittent denial‐of‐service (DoS) attacks. When DoS attacks occur, the sensor‐controller communication channel is jammed. This may result in system states and traditional backstepping methods are unavailable. A novel switching‐type state observer is constructed to overcome the aforementioned challenges. When the injection attacks occur, the input signals of the controller‐actuator communication channel are changed. A decentralized adaptive event‐triggered controller is designed by using the backstepping method, where a first‐order sliding mode differentiator is introduced to avoid “computational explosion.” The observer gain is derived via the linear matrix inequality technique simultaneously. By using an improved average dwell time method and Lyapunov function theory, all closed‐loop signals are bounded. Finally, a numerical example is used to verify the effectiveness of the proposed control scheme.
Radiofrequency Plasma‐Assisted Pulsed Laser Deposited Pt/TiOxNy Coatings on Multi‐Walled Carbon Nanotubes as Gas Diffusion Electrodes for the Oxygen Reduction Reaction

Published: June 2022

This study reports on the fabrication and characterization of novel multilayered electrocatalyst nanostructures for the oxygen reduction reaction (ORR). Thin titanium oxynitride (TiOxNy) coatings are deposited on a forest of multi‐walled carbon nanotubes (MWCNTs), directly grown on a stainless‐steel mesh, by capacitively coupled radiofrequency plasma‐assisted pulsed laser deposition (RF‐PAPLD) in a N2 environment. The resulting high‐surface‐area binder‐free electrode is further coated with a low quantity of well‐dispersed Pt nanoparticles (NPs) by PLD in an inert atmosphere. High‐speed imaging of the laser‐induced plasma expansion provided evidence of a higher kinetics of the expanding plume at higher RF plasma powers, changing the morphology of the TiOxNy coatings. X‐ray photoelectron spectroscopy demonstrated that the coatings are homogeneous throughout their thickness, where the TiN, TiON, and TiO bonds exist in all samples. The oxygen content of the coating increases with the RF plasma power. Both TiOxNy/MWCNT and Pt/TiOxNy/MWCNT nanostructures are tested in a gas diffusion electrode setup to evaluate their activity in the ORR. The results showed the superior activity of the Pt/TiOxNy‐0.03 Torr‐30 W/MWCNT, reaching the highest current density of 180 mA cm−2, while the commercial Pt/C electrode with the same Pt loading yielded 105 mA cm−2 at the potential of 0.5 V.

Combining the characteristics of hybrid perovskites and layered materials, 2D Ruddlesden–Popper perovskites exhibit unique properties, some of which still require to be deeply understood. In this study, the vibrational signatures of such materials are analyzed by collecting experimental Raman spectra of four distinct compounds. Supported by density functional theory simulations, the role of the phenyl spacer single fluorination on the phonon modes of two similar yet different compounds, i.e., phenethylammonium lead iodide (PEAI) and 4‐fluorophenethylammonium lead iodide (PEAI‐F), is explained. In addition, this work analyzes some so‐far unreported experimental Raman peaks in the 600–1100 cm−1 range and discusses their origin in this class of 2D compounds. This work paves the way for a better design of novel compounds as well as for their exploitation in (opto)electronic applications.

Photodetectors (PDs) are essential for promoting the modern technology‐reliant lifestyles. Accordingly, the demand for efficient PDs with built‐in signal amplification capabilities is constantly increasing. Generally, built‐in signal amplification is achieved using an avalanching process that operates at a high bias voltage with inevitable excess noise. In this study, back‐to‐back Schottky diodes (BTB SDs) are designed to demonstrate a significant amplification of signals at low bias voltages with relatively low excess noise. Furthermore, the detection efficiency is bilateral and relies less on the illuminated junction or the bias polarity, but is influenced by the wavelength of the illuminating light owing to the specific device structures employed. This enables the identification of the color of the incident light without using any color filters. The BTB graphene–insulator–silicon‐on‐insulator (BTB G–I–SOI) PDs fabricated with controlled interfacial oxides exhibit photoresponsivity up to 2.01 × 104 A W−1, specific detectivity of 1.57 × 1014 cm Hz1/2 W−1 at 5 V, and a rapid response (≈0.3 ms) for a two‐millimeter‐long channel. Thus, BTB G–I–SOI PDs are highly efficient filterless color sensors that establish a novel route for diverse applications of PDs.

Li4Ti5O12 (LTO) is the most famous Li+‐storage anode material with fast‐ and stable‐charging capability, but suffers from several disadvantages, such as poor electron conduction, low energy density, and disappointing high‐temperature performance. Here, LaCeNb6O18 (LCNO) micrometer‐sized particles are explored as a fast‐ and stable‐charging anode material superior to LTO sub‐micrometer‐sized particles in terms of the working potential, rate capability, and high‐temperature performance. The conductive Ce3+ and Nb5+↔Nb3+ reactions in LCNO, respectively, enable its significantly larger electronic conductivity and lower working potential than those of LTO. LCNO owns a very open A‐site‐cation‐deficient perovskite structure, in which (vacancy/La/Ce)O12 layers with electrochemical inactivity and superior volume‐buffering capability locate between active NbO6 layers, leading to not only fast Li+ diffusivity but also low‐ and negative‐strain behavior at different temperatures. At 25 °C, LCNO exhibits higher rate capability (50 vs 0.1 C capacity ratio of 67.9%) than that of LTO, and excellent cyclability. At 60 °C, LCNO maintains excellent cyclability, and achieves larger reversible capacity and even higher rate capability, whereas the high temperature lowers all the electrochemical properties of LTO. Therefore, LCNO holds great promise for fast‐ and stable‐charging applications in a wide temperature range, even when its particle sizes are on the order of micrometers.

Objectives

Bonobos and chimpanzees do not differ from one another in overall frequencies of arboreality versus terrestriality as much as once thought. Thus, at a broad level, one would predict that there is little difference in foot morphology among Pan taxa. However, behavioral data suggest that bonobos more often use smaller diameter substrates (<10 cm) when climbing whereas western chimpanzees frequently climb larger diameter (>15 cm) substrates. This study tests the hypothesis that if Pan medial cuneiform and talus morphology reflects these substrate preferences, then the morphology of these bones should favor hallucial grasping in bonobos and an inverted foot set in western chimpanzees.

Materials and Methods

Three‐dimensional geometric morphometric (3DGM) methods were used to explore shape variation in 126 talus and 127 medial cuneiform 3D surface models acquired from 108 chimpanzees (24 western, four Nigeria‐Cameroon, 33 central, 32 eastern, and 15 captive unknowns) and 22 bonobos

Results

The shapes of the talus and medial cuneiform in Pan covary as a functional unit emphasizing hallucial grasping with a less inverted foot set in bonobos and a more inverted foot set with a less abducted hallucial set in western chimpanzees. Other chimpanzee subspecies fall between these two extremes.

Discussion

Bonobo and western chimpanzee medial cuneiform and talus shapes are consistent with their differing preferences for using smaller and larger diameter substrates, respectively, when vertically climbing. These results suggest that even among closely related taxa, foot, hand, and other postcranial anatomy may be fine‐tuned for specific locomotor behaviors or preferences.

Despite extensive research toward the development of point‐of‐care nucleic acid tests (POC NATs) for the detection of microRNAs (miRs) from liquid biopsies, major hurdles remain including the strict requirement for extensive off‐chip sample preprocessing. Herein, a nucleic acid lateral flow test (NALFT) is reported on that enables the direct detection of endogenous miRs from as little as 3 μL of plasma without the requirement for any enzyme‐catalyzed target amplification or complex miR extraction steps. This is achieved through integration of a denaturing hydrogel composite material onto the LFT, allowing for near‐instantaneous on‐chip release of miRs from their carriers (extracellular vesicles or transport proteins) prior to detection. This next‐generation LFT is sensitive enough to detect endogenous concentrations of miR‐150‐5p, a predictive biomarker for preterm birth (PTB) found deregulated in maternal blood from as early as 12th week of pregnancy. Herein, a key step is represented toward a first bedside test for risk‐stratification during pregnancy by predicting true outcome at a very early stage. More generally, the universal and versatile nature of this novel sample preprocessing platform can further improve the robustness of existing NALFTs and facilitate their application at the POC.

Wir stellen hiermit die Synthese eines nahezu quadratisch‐pyramidalen Chlorophosphorans vor, das von dem tetradentaten Bis(amidophenolat)‐Liganden N,N′‐bis(3,5‐di‐tert‐butyl‐2‐phenoxy)‐1,2‐phenylendiamid getragen wird. Nach Chloridabstraktion fördert das resultierende Phosphoniumkation effizient die Dis‐proportionierung von 1,2‐Diphenylhydrazin zu Anilin und Azobenzol. Mechanistische Studien, spektroskopische Analysen und theoretische Berechnungen legen nahe, dass diese beispiellose Reaktivität für PV‐Zentren durch die hohe Elektrophilie des kationischen PV‐Zentrums verursacht wird, die auf die geometrischen Einschränkungen durch den starren Pincer‐Liganden zurückzuführen ist, kombiniert mit der Fähigkeit der o‐Amidophenolat‐Komponenten, als Elektronenreservoir zu fungieren. Diese Studie veranschaulicht die vielversprechende Rolle der Kooperativität zwischen redox‐aktiven Liganden und Phosphor für die Entwicklung von Organokatalysatoren, die Redoxprozesse fördern können.

Controllable nitrogen doping is an effective way to regulate the electronic properties of graphene and further to facilitate its wider application. However, the synthesis of high‐quality nitrogen‐doped graphene (NG) with a controllable nitrogen configuration still faces considerable challenges. In this work, we present for the first time a simple method for the one‐step synthesis of NG with ionic liquids (ILs) as precursors, which avoids the defects introduced by secondary doping and simplifies the process. Using 1‐Ethyl‐3‐methylimidazolium dicyanamide (EMIM‐dca) as the precursor, we obtained a high‐quality NG with few defects (ID/IGis 0.83), nitrogen content (4.11 at%), and graphite‐N proportion of 92% at a growth temperature of 1000 °C and field effect transistors (FETs) fabricated on SiO2/Si substrates using the NG exhibited typical n‐type semiconductor behavior in air. Our findings bring more inspiration for the controllable growth of high‐quality graphitic N‐doped graphene, thereby promoting its application possibilities in numerous fields.
