Boosting the Faraday Efficiency of Electrochemical Ammonia Synthesis via the Strain Effect Induced by Interfacial Hybrid Formation between BN and Carbon Nanotubes.

The electrochemical nitrogen reduction reaction (eNRR) is a highly promising alternative to the Haber-Bosch (H-B) process, but its commercial development is limited by the high bond energy of N2 molecules and the presence of the competitive hydrogen evolution reaction (HER). Here, a metal-free composite electrocatalyst of boron nitride (h-BNNs) and carbon nanotubes (CNTs) was explored through the interfacial hybridization of h-BNNs and CNTs, which showed a highly improved eNRR Faraday efficiency (FE) of 63.9% and an NH3 yield rate of 36.5 μg h-1 mgcat.-1 at -0.691 V (vs RHE). New chemical bonds of C-B and C-N were observed, indicating a strong interaction between CNTs and h-BNNs. According to the Raman spectra and the optimized model of h-BNNs/CNTs, an obvious strain effect between h-BNNs and CNTs was supposed to play a significant role in the highly improved FE, compared with the FE of h-BNNs alone (4.7%). Density functional theory (DFT) calculations further showed that h-BNNs/CNTs had lower energy barriers in eNRR, giving them higher N2 to NH3 selectivity, while h-BNNs have lower energy barriers in the HER. This work shows the important role of the strain effect in boosting the selectivity in the eNRR process.

Effects of hybrid metallic wastes on strength and durability of cementitious mortars

The amount of industrial waste is increasing along with the rise in industrial production. Therefore, reusing or recycling this harmful waste is quite a significant issue for waste management. A suitable use for industrial wastes is to incorporate them in concrete, the most widely used material in the world. In this study, grinding swarf, which had not been used in cementitious composites before, and metal shavings produced in the computer numerical control (CNC) milling process were used. The effects of these wastes on the strength and durability of cement mortars were investigated by using them separately and in hybrid forms. Flowability, fresh unit weight, compressive strength, flexural strength, water absorption and high-temperature effect tests were conducted on mortar samples. Although the wastes exhibited a positive contribution when used alone, they yielded the highest contribution when combined. When the waste materials were used in a hybrid form, they increased compressive strength, flexural strength and high-temperature resistance by 29%, 12.98% and 49.50%, respectively. Owing to their physical and chemical composition, metal shavings showed fibre effects, while grinding swarf improved strength and durability.

The unheard voices of academia: overcoming systemic barriers and fostering inclusive spaces for knowledge exchange

Our paper aims to consider how hybrid academic conferences can create inclusive spaces for knowledge exchange. The paper begins by considering the purpose of academic conferences and identifying the groups of people excluded when conferences are run in an in-person-only format. Reasons for exclusion include being disabled, being a carer, being unable to travel (e.g. in the final trimester of pregnancy), being unable to secure a VISA, or being unable to access funds to cover travel and accommodation costs. Next, we consider the existing challenges that individuals and event organizers face concerning academic conferences. Then, pragmatic opportunities for event organizers are presented, making the case for running conferences in a hybrid format. The paper concludes with a call to action for promoting care democracy in the workplace by addressing the humanity deficit and the unheard voice of academics currently excluded from in-person-only academic conferences.

Selective Formation of Pd-DNA Hybrids Using Tailored Palladium-Mediated Base Pairs: Towards Heteroleptic Pd-DNA Systems.

The formation of highly organized metal-DNA structures has significant implications in bioinorganic chemistry, molecular biology and material science due to their unique properties and potential applications. In this study, we report on the conversion of single-stranded polydeoxycytidine (dC15 ) into a Pd-DNA supramolecular structure using the [Pd(Aqa)] complex (Aqa=8-amino-4-hydroxyquinoline-2-carboxylic acid) through a self-assembly process. The resulting Pd-DNA assembly closely resembles a natural double helix, with continuous [Pd(Aqa)(C)] (C=cytosine) units serving as palladium-mediated base pairs, forming interbase hydrogen bonds and intrastrand stacking interactions. Notably, the design of the [Pd(Aqa)] complex favours the interaction with cytosine, distinguishing it from our previously reported [Pd(Cheld)] complex (Cheld=chelidamic acid). This finding opens possibilities for creating heteroleptic Pd-DNA hybrids where different complexes specifically bind to nucleobases. We confirmed the Pd-DNA supramolecular structural assembly and selective binding of the complexes using NMR spectroscopy, circular dichroism, mass spectrometry, isothermal titration calorimetry, and DFT calculations.

IV International Scientific and Practical Conference “Homo Legens in the Past and the Present”

The article is devoted to the IV International scientific and practical conference "Homo legens in the past and the present" held in Novosibirsk and Nizhny Tagil on March 23-25, 2023 in hybrid format. The author aims to provide a general overview of events held within the framework of the scientific forum and to characterize the speeches of researchers, teachers, librarians and students, who took part in it. The relevance of the described event is related to the changes that reading practices are undergoing during the explosive spread of screen culture. The outflow of readers from libraries and the decline in print editions led to the interest of specialists in such problems as forms of reading support, the interaction between reader and book in the library space, issues related to the book design. This review can be beneficial for both to theorists and practitioners working in the field of book and library business as well as for specialists engaged in serving readers and popularizing reading.

Temperature-dependent elasticity of DNA, RNA, and hybrid double helices

Nucleic acid double helices in their DNA, RNA, and DNA-RNA hybrid form play a fundamental role in biology and are main building blocks of artificial nanostructures, but how their properties depend on temperature remains poorly understood. Here, we report thermal dependence of dynamic bending persistence length, twist rigidity, stretch modulus, and twist-stretch coupling for DNA, RNA, and hybrid duplexes between 7°C and 47°C. The results are based on all-atom molecular dynamics simulations using different force field parameterizations. We first demonstrate that unrestrained molecular dynamics can reproduce experimentally known mechanical properties of the duplexes at room temperature. Beyond experimentally known features, we also infer the twist rigidity and twist-stretch coupling of the hybrid duplex. As for the temperature dependence, we found that increasing temperature softens all the duplexes with respect to bending, twisting, and stretching. The relative decrease of the stretch moduli is 0.003–0.004/°C, similar for all the duplex variants despite their very different stretching stiffness, whereas RNA twist stiffness decreases by 0.003/°C, and smaller values are found for the other elastic moduli. The twist-stretch couplings are nearly unaffected by temperature. The stretching, bending, and twisting stiffness all include an important entropic component. Relation of our results to the two-state model of DNA flexibility is discussed. Our work provides temperature-dependent elasticity of nucleic acid duplexes at the microsecond scale relevant for initial stages of protein binding.

“My Soul, Why Art Thou Full of Trouble”: Hester Pulter’s Apostrophe to the Soul

Abstract The poems of Hester Pulter (1605–1678) provide insight into the religion and politics of a woman writing through the English Civil Wars and Republic. This paper focuses on Pulter’s use of the apostrophe to the soul and on her abstention from employing disciplinary metaphors that so often characterise devotional poetry. In merging the devotional apostrophe to the soul with complaint, Pulter effectively jettisons the penitential aspects of these approaches, creating a hybrid form in which her body provides comfort to her grieving soul. Pulter thus creates a form of devotional poem that relies on an aesthetics of comfort instead of discipline. By utilising the affordances of the apostrophe – its ability to bring the speaker and its addressee into a relation with one another – Pulter enacts a spiritual unification and in so doing makes implicit claims about the emotional and spiritual efficacy of poetry.

Abstract B037: ClonMapper Duo: An scRNAseq compatible lineage tracing method to track cell-cell fusion at single-cell resolution

Abstract Spontaneous cell-cell fusion in cancer can generate genetic heterogeneity and often leads to more pathological phenotypes. While the consequences of cell-cell fusion in cancer continue to be revealed, few tools exist to determine the mechanisms and cell states which promote cell-cell fusion. To meet this need, we engineered ClonMapper Duo, a two-color, two-index expressed barcoding system which allows tracking of cell-cell fusion using live-cell imaging and lineage tracing of fusion cells in scRNAseq. The ClonMapper Duo system was created by modifying the ClonMapper DNA barcoding system to express indexed barcodes on either H2B-GFP or H2B-mCherry. Briefly, 8 unique 5-nucleotide sequences were designed by maximizing Hamming distance and 4 sequences were assigned to GFP and mCherry each. The index sequences were placed adjacent to a 15N random nucleotide in the expressed barcode region of the construct. Low-diversity GFP and mCherry barcoded cell libraries were created through lentiviral transduction of HCC1806, MDA-MB-231, and MCF-7 cells. Diversity and evenness of each library was confirmed via targeted barcode sequencing. For each cell line, homotypic GFP and mCherry barcoded cells were cocultured together for 1 week. A parallel culture was monitored using live-cell imaging to measure the rate of spontaneous cell-cell fusion and the probability of different fates (e.g. death, hybrid formation, senescence) for each cell line. Spontaneously fused cells identified by expression of both GFP and mCherry were enriched by FACS. Enriched fusion cells were expanded in parallel with the parental cocultures until ~1e5 fusion cells or 1 week was reached. Fusion and parental populations for each cell line were multiplexed for scRNAseq using the 10X Genomics 3’ CellPlex Kit. FACS enriched multibarcoded fusion cells were further bioinformatically distinguished from cell multiplets and the barcodes of spontaneously fused cells were traced to their single-barcoded cell lineage of origin. From this data set we ask: 1. Are certain cell lineages more primed for fusion than others, i.e. does a more fusogenic cell phenotype exist or is fusion random? 2. Is there a convergent state of post-fusion cells or does fusion tend to diversify phenotypes? Here, we will present the first results from this two-color, two-index live-cell imaging and scRNAseq lineage tracing system toward understanding cancer cell-cell fusion at a single cell resolution. Combining lineage traced transcriptomic data from scRNAseq with fusion rates and outcomes from live-cell imaging using ClonMapper Duo provides an unprecedented look into the causes and consequences of spontaneous cell-cell fusion in cancer.

Nuclear gene introgressions in hybrid populations of water frog Pelophylax esculentus complex: geographical analysis of the phenomenon and its interpretation.

Reproduction of water frog hybrids Pelophylax esculentus (Pelophylax ridibundus x Pelophylax lessonae) is associated with hemiclonal reproduction and backcrossing. The hemiclonal mode of reproduction occurs within P. esculentus allodiploids. In this case, the unrecombined genome of one parental species is transmitted to the offspring after premeiotic elimination of the chromosome set of the second parental species. Usually, the chromosome set of P. lessonae is eliminated, and the altered genome of P. ridibundus is passed on to the progeny. The hemiclonal inheritance within diploid Pelophylax esculentus hybrids may be accompanied by certain aberrations of premeiotic elimination. As a result, the formation of P. ridibundus specimens with introgressions of the P. lessonae genetic material, or the formation of recombinant hybrids occurs, depending on which of the parental species backcrossing takes place. The aim of our study is to describe the aberration of premeiotic elimination within the water frog P. esculentus complex detected by the nuclear gene Ldh-B inheritance, with an attempt to find out the causes of this phenomenon. It has been established that aberrations of premeiotic elimination are widespread, but only within populations of water frog from the river system of Upper Dnieper within Ukraine. The highest level of introgression takes place in the water frog populations within Kiev metropolis under conditions of expressed anthropogenization, while the maximum frequency of recombinants was detected within populations from the basin of Desna River, that has preserved native ecosystems. It was demonstrated that the frequency of premeiotic aberrations does not correlate with the intensity of interspecific water frog hybridization. Populations with introgressions are more common than populations with recombinants, however, within the latter, the frequency of recombination events is higher. The primary factor of gametogenesis aberrations, most likely, is the genetic characteristics of the local populations of parental species, since unambiguous explanations of this phenomenon based on the action of environmental stress (pollution of water systems) are not obvious.

Distributed Leader Follower Formation Control of Mobile Robots Based on Bioinspired Neural Dynamics and Adaptive Sliding Innovation Filter

This paper investigated the distributed leader follower formation control problem for multiple differentially driven mobile robots. A distributed estimator is first introduced and it only requires the state information from each follower itself and its neighbors. Then, we propose a bioinspired neural dynamic based backstepping and sliding mode control hybrid formation control method with proof of its stability. The proposed control strategy resolves the impractical speed jump issue that exists in the conventional backstepping design. Additionally, considering the system and measurement noises, the proposed control strategy not only removes the chattering issue existing in the conventional sliding mode control but also provides smooth control input with extra robustness. After that, an adaptive sliding innovation filter is integrated with the proposed control to provide accurate state estimates that are robust to modeling uncertainties. Finally, we performed multiple simulations to demonstrate the efficiency and effectiveness of the proposed formation control strategy.

The carbon footprint of American Academy of Orthopaedic Surgeons and Pediatric Orthopaedic Society of North America national meetings

BackgroundThe health care sector contributes substantially to carbon emissions. Estimating the carbon emissions of an event can help determine its climate impact. This study calculates the carbon footprints of the 2019 American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting and the 2019 Pediatric Orthopaedic Society of North America (POSNA) Annual Meeting. MethodsData regarding attendance volume, geographic origin of attendees and vendors, hotel room nights, event space, and duration of meetings were obtained from AAOS and POSNA. Data were entered into an online calculator designed to measure the carbon footprint of large events (www.terrapass.com). ResultsThe AAOS 2019 annual meeting was attended by 29 448 people, requiring 66 000 hotel room nights and 2 308 800 ft2 of convention center space for 5 days. We estimated 7179 short, 8374 medium, and 13 421 long-haul round-trip flights. The POSNA 2019 annual meeting was attended by 1103 people, requiring 1932 hotel room nights and 52 100 ft2 of convention center space for 4 days. We estimated 501 short, 280 medium, and 280 long-haul round-trip flights. The AAOS 2019 meeting emitted 26 075 metric tonnes of carbon dioxide equivalents (CO2e), while the POSNA 2019 meeting emitted 544 metric tonnes. Eighty-one percent of the carbon emissions from AAOS and 80% from POSNA came from flight travel alone. Carbon neutralization of in-person AAOS and POSNA annual meetings would require carbon-offset purchases of approximately $273 700 and $5700, respectively. ConclusionsAnnual orthopaedic meetings contribute to climate change through their large carbon footprint. Leaders in the field of orthopaedics should consider strategies to mitigate the impact of such meetings, examples of which include transitioning to hybrid formats when appropriate and by purchasing carbon offsets for essential in-person participation. Key Concepts1)Calculating the carbon footprint of an event estimates its total carbon dioxide emissions to help determine how to reduce its climate impact.2)The AAOS 2019 meeting emitted 26 075 metric tonnes (MT) of carbon dioxide equivalents (CO2e), while the POSNA 2019 meeting emitted 544MT, with ∼80% coming from air travel alone.3)Carbon neutralization of in-person AAOS and POSNA annual meetings would require carbon-offset purchases of approximately $273 700 and $5700, respectively.

Objective: The objective of this research was to explore the Universal People's Security Defense System that has not been well socialized in anticipating future threats. The aim of this research is to realize an anticipatory Urban Warfare strategy by creating a General National Defense Policy for 2025-2030 in the Neo' Post-Truth Era in Indonesia. Method: The qualitative method used in this research is a case study approach. Through literature study data collection and analyzing several rules regarding the urban warfare strategies, the research focused on how these elements mold the future policy on the neo ‘post truth era in Indonesia. Results: The facts about the threats of radicalism, terrorism, insurgency, separatism and social revolution change the arrival of military, non-military and hybrid threats into a new categorization of threats in the form of asymmetric, proxy, hybrid and information threats as urban warfare threats. Various countries have experienced the problem of urban warfare starting from the Arab Spring in the Middle East, African countries, South Asia and Southeast Asia, including Indonesia. The results of this research show, first, the forms of threats in the world and Indonesia in the form of asymmetric, proxy, hybrid and information threats. Second, the policy and implementation are in accordance with the General State Defense Policy in the Neo' Post-Truth Era in Indonesia in the form of a policy of balancing security and prosperity. Third, Anticipatory Strategy for Urban Warfare in the Neo ‘Post-Truth era in Indonesia in the form of intelligence cooperation, diplomacy and operations. The conclusion of this research requires the creation of the latest 2025-2030 jakum hanneg in anticipating Urban Warfare in Indonesia. Conclusion: Urban warfare is complex and challenging. This operation is not only military in nature, but also has many aspects because it must take into account the economic, social and other characteristics of the city. Successful urban operations require specialized strategy and training, as well as adapted weapons and equipment. Implementation policy general national defense can involve development strength reliable military and non -military for capable face threat in environment urban areas, including effective strategies and tactics in face urban warfare. This is possible involve training special for personnel military in urban battle, development appropriate technology and equipment for operation urban, as well good planning and coordination between various units and agencies involved in national defense. Apart from that, implementation policy general national defense can also cover effort to build cooperation with parties related in face threat of urban warfare. This can involve cooperation with police, government region, and society civil in effort for increase security and preparedness in face threat in urban environment.

Institutional Theory and Hybrid Accounting and Control Systems

ABSTRACT We identify several manifestations of hybridity in accounting and control systems. Hybridity in the form of multiple accounting systems and actual or postural conformity to institutional expectations can enable organizations to overtly, but sometimes ostensibly, combine multiple logics to appease stakeholders. Hybridity increases costs and the risk of internal inconsistency. Consequently, firms decouple some practices to provide an impression of conformance. We offer a typology of three forms of hybridity—compliance, complete decoupling, and partial decoupling—and illustrate using examples from accounting hybridization choices regarding corporate social responsibility (CSR), diversity, equity, and inclusion (DEI), and international reporting standards. We empirically examine hybridity in the context of the voluntary adoption of international financial reporting standards (IFRS). We find that instrumental pressures are associated with adoption through compliance; however, social pressures are likely to be placated through complete decoupling, whereby firms voluntarily adopt multiple systems in policy, but not in practice.

Inter-Organisational Collaboration Structures and Features to Facilitate Stakeholder Collaboration

Although inter-organisational collaborative structures play a vital role in determining the level of collaboration among organisations, the identification of required organisational structural types and their features to facilitate fruitful collaboration is not satisfactorily discussed in existing studies. In addition, the connection between inter-organisational structural types and features, and their influence on collaboration, is not well understood. This systematised literature review study explores the available inter-organisational collaborative structural types, features, and their suitability to facilitate collaboration among organisations. Our findings underscore the importance of adopting a hybrid form of hierarchy and network arrangements to facilitate effective collaboration among organisations. Furthermore, this study developed a framework that presents how collaboration depends on inter-organisational structures and their features in facilitating vertical and horizontal integration. This framework can be used to identify the inter-organisational collaboration structures that are required to move towards a desired inter-organisational collaboration level.

Hybrid Interpersonal Violence in Latin America: Patterns and Causes.

In this review, we argue that to understand patterns and causes of violence in contemporary Latin America, we must explicitly consider when violence takes on interpersonal qualities. We begin by reviewing prominent definitions and measurements of interpersonal violence. We then detail the proliferation of interlocking sources of regional insecurity, including gender-based violence, gangs, narcotrafficking, vigilantism, and political corruption. Throughout this description, we highlight when and how each source of insecurity can become interpersonal. Next, we outline mutually reinforcing macro and micro conditions underlying interpersonal violence in its many hybrid forms. To conclude, we call for more multifaceted conceptualizations of interpersonal violence that embrace the complexities of Latin American security situations and discuss the opportunities and challenges that lie ahead in this area.

Cattleya × paulae (Orchidaceae—Laeliinae), a new nothospecies from Sempre-Vivas National Park, Minas Gerais, Brazil

Numerous species of Cattleya ser. Parviflorae often coexist in the same habitat, and hybrids can occur when their flowering seasons overlap or when one species initiates blooming shortly after another. The formation of hybrids will depend on whether the flowers of both species are structurally compatible. Most Cattleya ser. Parviflorae species are saxicolous or rupicolous and grow on granite and gneiss coastal mountains or on rock outcrops of quartzitic iron ore. Sympatric populations of Cattleya rupestris and Cattleya porphyrascens were encountered within the Sempre-Vivas National Park (PNSV), together with a new nothospecies on a rock outcrop it shared with those parent species. This study provides an illustrative plate comparing the labellum of the nothospecies with its parental species, as well as a map indicating its location within the National Park.

Evaluating Effectiveness of Telerehabilitation Services Among Injured Workers Treated in a Canadian Workers' Compensation System: A Population-Based Study.

To evaluate the effectiveness of telerehabilitation for promoting return-to-work (RTW) among injured workers. We conducted a pragmatic, quasi-experimental study comparing telerehabilitation, in-person, or hybrid services. Descriptive statistics analyzed demographics, occupational factors, and patient-reported outcome measures (PROMs). Kruskal-Wallis tests investigated differences between mode of delivery and changes in PROM scores. Logistic and Cox-proportional hazard regression examined associations between mode of delivery and RTW status or days receiving wage replacement benefits in the first-year post-discharge, respectively, while controlling for potential confounders. A slightly higher percentage of the 3,708 worker sample were male (52.8%). Mean (standard deviation (SD)) age across all delivery formats was 45.5 (12.5) years. Edmonton zone had the highest amount of telerehabilitation delivery (53.5%). The majority of workers had their program delivered in a hybrid format (54.1%) and returned to work (74.4%) at discharge. All PROMs showed improvement although differences across delivery formats were not clinically meaningful. Delivery via telerehabilitation had significantly lower odds of RTW at discharge (Odds Ratio: 0.82, 95% Confidence Interval: 0.70-0.97) and a significantly lower risk of experiencing suspension of wage replacement benefits in the first year following discharge (Hazard Ratio: 0.92, 95% Confidence Interval: 0.84-0.99). Associations were no longer significant when confounders were controlled for. RTW outcomes were not statistically different across delivery formats, suggesting that telerehabilitation is a novel strategy that may improve equitable access and earlier engagement in occupational rehabilitation. Factors such as gender and geographic location should be considered when deciding on service delivery format.

Transformation Model of Institutional Arrangements of Indigenous People To Become Customary Villages: Experiences From Indonesia

Objective: this research is motivated by the problem of Law Number 6 of 2014 concerning Villages (Village Law), which forces indigenous people (MHA) to merge and refer to the nomenclature "Customary Village" if they want to be recognized by the state. It is feared that such an arrangement will fail to recognize MHA. This research aims first to analyze the transformation model of the institutional arrangements of the Baduy, Tengger, and Minangkabau indigenous peoples to become Customary Villages. Second, to analyze the Regional Government's policy strategy in creating an inclusive region for MHA. Methods: the focus of this research will be studied using normative research methods and statutory and conceptual approaches. Conclusions: this research concludes that first, the transformation model of the institutional arrangements of the Baduy, Tengger, and Nagari indigenous peoples to become Customary Villages varies in form due to having different philosophical, sociological, juridical, and political backgrounds. a) Baduy MHA is transformed into a hybrid form because it adopts the concept of a modern village and customary simultaneously; b) MHA Tengger is transforming into a modern village but is working again as a Customary Tourism Village. c) Minangkabau MHA has been fully transformed into a customary village. Second, the Regional Government's policy strategy in creating an inclusive region for MHA can be in the form of adjusting the needs and degree of recognition and protection desired by MHA. There are several alternative forms of various policies and different forms of recognition and protection materials.

Comparative study of the growth, survival and morphology of the whitefish hybrids and parent species in the first year of rearing in cage aquaculture

The purpose of the work: to estimate fish breeding indicators of three hybrid forms of whitefish in comparison with parental species when grown in cage aquaculture.Methods used: the production and cultivation of hybrids and parental species were carried out using standard technology for whitefish from November 2021 to May 2022. We have studied the survival and growth rate of fingerlings, and we also conducted a comparative assessment of the exterior of yearlings using factor and cluster analyses.Novelty: for the first time, three hybrid forms of peled and parent species (peled, muksun, broad whitefish, nelma) were grown in cages, and a comparative analysis of survival, growth and morphology of hybrids and parent species was performed.Results: all hybrid forms occupy an intermediate position in terms of growth rate, surpassing the maternal species (peled), yielding to the paternal ones. The best results in terms of weight and linear growth among hybrids were noted in pelchir. In terms of survival, oneyearlings of all hybrids show the effect of heterosis, although at the stage of larvae and early juveniles, the superiority in survival of hybrid forms over the parental pair was noted only in pelnelm. The survival rate of hybrid eggs, as well as the survival rate of pelchir and pelmuk at the early stages of cultivation, had intermediate values — lower than that of peled, but significantly higher than that of paternal species. The lowest survival rate of eggs among hybrids is shown in pelchir. The peled has the most significant morphological differences from other pure species and hybrid forms used in the experiment, all hybrid forms show more similarity with the paternal species.Practical significance: results provide a potential assessment of whitefish hybrids for the prospect of their use in commercial aquaculture.
