Strategies for Co-Creation and Co-Governance in Urban Contexts: Building Trust in Local Communities with Limited Social Structures

Over the last few years, community empowerment has become a central focus when discussing the sustainability of large-scale urban regeneration processes, especially those related to the implementation of nature-based solutions. In this article, the authors describe the experience of the CLEVER Cities project in the city of London, by looking at the dynamics of the early stages of co-creation and the implications on co-governance, motivation and policy. Particular attention is given to the importance of carefully evaluating the project context to guide where emphasis is given on the use of specific co-creation strategies such as building trust, raising awareness or networking. In this case, a set of strategies emerge that are a response to several factors but are strongly influenced by the backdrop of limited social structuring encountered in South Thamesmead, South London. The methods are derived based on a qualitative and looped observation approach over three phases applied to three urban living labs in the project area. Finally, to structure the results, an iterative co-production of knowledge approach is used to cluster the strategies into ten more synthetic recommendations based on collaborative governance, communication and capacity building, as well as incentives and motivation. Further, guidance is given by highlighting priorities to inform policy and place-based planning actions.
Trajectory Optimization for Maneuvering Platform Bistatic SAR With Geosynchronous Illuminator

Geosynchronous synthetic aperture radar (GEO-SAR) can provide long-duration and wide beam coverage over the interested target scene, which is an ideal illuminator for bistatic SAR acquisitions. As a particular system configuration, the GEO bistatic SAR with a maneuvering platform as the receiver (GEO-MP-BiSAR) can achieve continuous observation of the interested target during the flight. The target recognition and tracking information can be generated from the updating images for enhanced guidance performance. However, the bistatic SAR imaging performance is dependent on the observation geometry, which, in turn, is determined by the trajectory of the receiver. Therefore, in this article, the trajectory optimization for GEO-MP-BiSAR is first investigated. The goal of the method is to generate a set of feasible trajectories to guide the maneuvering platform toward the target, and meanwhile obtain the optimized imaging performance during the whole flight. The trajectory optimization is then modeled as a multiobjective optimization problem with multiple constraints, where the trajectory control and SAR imaging performance are comprehensively considered. Then, a knee-guided multiobjective evolutionary algorithm (KG-MOEA) is put forward to effectively solve the problem, where the knee solutions are utilized to guide the search process and improves convergence and diversity of the method. The proposed algorithm can generate the prescribed number of solutions with significant trade-offs between the performance metrics. The mission designer can then choose a solution from only a few optimized candidates for implementation, which greatly improves the efficiency of decision making. Experimental studies demonstrate the effectiveness of the proposed method.
Ecological and Public Advantages of a Dual Flagship Strategy: Giant Panda and Snow Leopard

Flagship species’ conservation strategies hold significant prominence in biodiversity preservation. The giant panda, a globally recognized species, has drawn attention to its benefits and constraints as a flagship species. This study aimed to assess the potential benefits of a dual flagship strategy using both the giant panda and snow leopard, compared to an approach solely using the giant panda. We identified the number of potential beneficiary species based on their habitat overlap with the giant panda and snow leopard in Sichuan and Gansu, China. Subsequently, we examined public preferences for these two flagships and their influencing factors through questionnaire surveys within and outside China. The dual flagship strategy covered the habitats of more species and amplified existing protection for those species already benefiting from giant panda conservation efforts. The giant panda was commonly perceived as “Adorable”, “Innocent”, and “Rare”, while perceptions of the snow leopard leaned towards “Mighty”, “Mysterious”, and “Rare”. Though the giant panda is widely favored, the survey indicates a notable preference for snow leopards among a proportion of respondents. The dual flagship strategy offers expanded wildlife habitat coverage and benefits a broader range of species. Moreover, the combined appeal of the snow leopard and giant panda, each possessing unique charm and symbolism, holds the potential to garner broader societal interest and support. This study may serve as a reference for policy decisions in the Giant Panda National Park and other similar protected areas, optimizing conservation management and outreach initiatives for flagship species strategies. It may also benefit conservation strategies centered on other flagship species.
The Effect of Niobium Addition and Pre-Annealing on the Tensile Properties of 52CrMoV4 Spring Steel

In this study, the effect of niobium addition and a specific preheating process on the microstructure and tensile properties of 52CrMoV4 steel used in leaf springs was investigated. Flat and leaf spring materials were used to accomplish this aim. The flat materials under investigation were kept in a furnace for 90 min at 900 °C. A homogeneous microstructure was aimed for with the use of this pre-annealing heat treatment in addition to the standard process before rolling used to create NbC. Leaf spring production was carried out with flat materials that possessed various Nb contents, with or without pre-heating. Grain size measurement and tensile tests were performed on the flat and leaf springs. Additionally, scanning electron microscopy images were captured from the fractured surfaces after the tensile tests were carried out. The current study highlights the importance of Nb addition as an alloying element and the effect of the selected pre-annealing process in optimizing the grain structure and enhancing the tensile properties of leaf springs. The leaf spring with a Nb ratio of 0.0376 that was pre-annealed exhibited a finer grain structure (G = 11.3), greater tensile properties (YS = 1550 N/mm2 and UTS = 1688.6 N/mm2), and deeper tear valleys and larger dimples, indicating higher energy consumption during fracturing, according to the SEM images produced, in contrast with the other materials studied.
Machine Learning Approaches to Malicious PowerShell Scripts Detection and Feature Combination Analysis

With advances in communication technology, modern society relies more than ever on the Internet and various user-friendly digital tools. It provides access to and enables the manipulation of files, trips, and the Windows API. Attackers frequently use various obfuscation techniques PowerShell scripts to avoid detection by anti-virus software. Their doing so can significantly reduce the readability of the script. This work statically analyzes PowerShell scripts. Thirty-three features that were based on the script’s keywords, format, and string combinations were used herein to determine the behavioral intent of the script. Ones are characteristic-based features that are obtained by calculation; the others are behavior-based features that determine the execution function of behavior using keywords and instructions. Behavior-based features can be divided into positive behavior-based features, neutral behavior-based features, and negative behavior-based features. These three types of features are enhanced by observing samples and adding keywords. The other type of characteristic-based feature is introduced into the formula from other studies in this work. The XGBoost model was used to evaluate the importance of the features that are proposed in this study and to identify the combination of features that contributed most to the detection of PowerShell scripts. The final model with the combined features is found to exhibit the best performance. The model has 99.27% accuracy when applied to the validation dataset. The results clearly indicate that the proposed malicious PowerShell script detection model outperforms previously developed models.
Preliminary results of a study on short term effects of prescribed fire in pine stands in NW Spain

Short term effects cf prescribed burning experiments carried out in P. pinaster stands in the N.W. of Spain on fuels ; soil nutrients , soil microflora and forest floor meso fauna were studied. Fire intensities range from 21 to 420 Kw.m-1. The mean maximum temperature recorded on the litter duff interface was 408 °C ; the temperature was greater than 60°C for about 5 minutes (mean value). On the duff-soil interface, 59° was reached and 21 °C was measured 2,5 cm below the top of the mineral soil. Fires consumed 32 per cent of the total fuel and 55 per cent of the available fuel. Two years after the fires, the total fuel was practically equal to the prebum load but the available fuel represented 64 per cent of its initial load. Changes in soil (0-5cm layers) nutrients were very small. Soon after the fires a little increment for the organic matter content, a small drop in pH and an increment in K, ca, Mg and P were detected. Nitrogen content was practically equal to pre-fire level. Two years later, all the nutrients remained at the same initial level, except for Ca which was 65 per cent higher than before burning. The organic matter per cent was a little smaller than before fire but pH was higher. Some groups of the soil microflora, especially aerobic free living nitrogen fixers, were enhanced by the fire. The others remained at the same level as in unbumt areas. Forest floor mesofauna populations were affected by fire and depending on groups, duff heating and duff consumption, their recovery lasted from six months to three and a half years.
Status of endogenous endomycorrhizal fungi associated with cowpea (Vigna unguiculata L.) in the Sudano-Sahelian zone of Cameroon

The Sudano-Sahelian part of Cameroon is known for its severe climatic conditions and low soil fertility. Local farmers use chemical fertilisers to increase crop production, usually without moderation. As a result, there is environmental pollution such as soil acidification, production of greenhouse gases, and increased eutrophication. To face this situation, scientific research recommends ecological solutions such as bio-fertilisers to enhance soil fertility. In this context, the mycorrhiza symbiosis technology deserves special attention. Indeed, it is a beneficial association between soil fungi (Glomeromycota) and the roots of more than 85% of plants; the evaluation of the agronomic potential of these microorganisms has shown spectacular results under field conditions. This study analyses the status of indigenous arbuscular mycorrhizal fungi in the cowpea rhizosphere in the agro-ecological zone 1 of Cameroon. For this purpose, soil samples were collected from the Far North and North regions of Cameroon. Composite soil samples were obtained by mixing soils collected from three divisions per region. Cowpea was grown in pots on these composite soil samples for 3 months. At maturity, spores of mycorrhizal fungi were isolated and parameters including mycorrhization frequency and intensity, the specific spore’s density and richness were evaluated. The spores were characterised according to morpho-anatomical criteria. The results established that between localities, mycorrhization frequency varied between 7-19%; mycorrhization intensity, 7-17.28%; specific density, 0.66-44% and specific richness, 2-4%. Eight specimens of arbuscular mycorrhizal fungi in six genera were characterised: Acaulospora (A. kentinensis, A. myriocarpa); Ambispora sp; Diversispora epigae, Funneliformis mossea, Glomus (G. constrictum, G. manihotis, and G. maculosum) and Rhizophagus intraradices. G. constritum was predominant in all the studied sites, followed by R. intraradices, while Acaulospora myriocarpa was the rarest. These results pave the way for the selection of indigenous arbuscular mycorrhiza fungi for ecological cowpea production in this area.

Post-Cephalic White Spot Syndrome in Salmonids

This report documents a phenomenon in salmonids involving one or more white spots generally located in the mid-dorsal nape or occipital region immediately posterior of the fishes’ head. The syndrome, post-cephalic white spot (PCWS), varies widely among populations. When present it often is found in less than 0.1% of individuals in a population although in some instances occurrence rates can be considerably higher. This anomaly is easily overlooked and often goes unnoticed, especially when viewing a large number of fish. The white pigment spots, only a few millimeters in diameter in juveniles, grow allometrically and are larger in older fish. I first observed PCWS in juvenile sockeye salmon in 1975 (Fig. 1). These fish were progeny of adults from Nakvassin Creek at the west end of Port Herbert, a 4.8 km fiord on Baranof Island in Southeast Alaska. Adult salmon were collected and taken to the nearby National Marine Fisheries Service Field Station at Little Port Walter where they were spawned as part of a study to evaluate rearing of smolts in estuarine net pens (Wertheimer et al. 1983). Since first observing PCWS the anomaly has been found to occur in all five species of North American salmon, rainbow trout, Dolly Varden char, and Atlantic salmon. Documentation of these findings was accomplished through careful observations by myself and by the solicited assistance of many other individuals. Much of this information documents the presence of PCWS in 37 different populations of salmonids from Alaska, Washington, Oregon, British Columbia, New Hampshire, Australia, and Hokkaido, Japan. In some instances sufficient data were collected in certain stocks of wild-and hatchery-origin sockeye and coho salmon to provide preliminary estimates on PCWS occurrence rates in the populations (Fig. 2). Occurrence rate data were also collected on eight populations of hatchery-origin chinook salmon smolts from Alaska, British Columbia, and Oregon that ranged from 0.01 to 0.86 percent. While PCWS is found in all life stages including adults (Fig. 3) it is more commonly seen in juveniles suggesting, when present, the syndrome carries a distinct survival liability. Although it has been observed in both wild- and hatchery-origin salmonids PCWS is more commonly seen in hatchery populations (Fig. 4), perhaps because large number of hatchery-origin juveniles can often be more readily observed than large numbers of wild juveniles. However, in some instances, for example during monitoring of wild sockeye salmon smolts outmigrating from the Hugh Smith Lake system in southern Southeast Alaska, considerable numbers of PCWS juveniles are
Association of morning and evening physical exercise with sleep quality and insomnia: differences between chronotypes

Objective: to investigate the association of morning and evening physical exercise with sleep quality (duration, latency, awakenings, and self-perceived sleep quality) and insomnia, depending on the chronotype. Methods: Participants (n=2,050; 18-65y) were part of a population-based research, with virtual data collection. Multiple logistic regression models were conducted to analyze the association of physical exercise (yes/no; frequency; morning/evening) with sleep variables (outcome), among all participants and according to chronotype. Linear regression analysis assessed differences in sleep duration, latency, and nocturnal awakenings (outcomes) associated with physical exercise variables. Multiple analyzes were adjusted for age, sex, diet quality, BMI, smoking, and evening alcohol consumption. Results: Participants who performed physical exercise had better sleep parameters and its practice in the morning was associated with shorter sleep latency among early (OR=-0.49; 95%CI=0.25;0.94; p<0.05) and late chronotypes (β=-15.10; 95%CI=-28.39;-1.81; p<0.05). There was no effect of exercising in the evening among intermediate and late chronotypes, however, among early types, it was associated with a higher frequency of awakenings (OR=1.78; 95%CI=1.06;2.96; p<0.05) and insomnia (OR=1.91; 95%CI=1.04;3.53; p<0.05). Conclusions: Such findings suggest the need to consider chronotypes, along with existing recommendations for sleep hygiene and circadian hygiene, in clinical-epidemiological physical activity strategies focused on promoting sleep quality and circadian health.
Bone Plate Composed of a Ternary Nanohydroxyapatite/Polyamide 66/Glass Fiber Composite: Biocompatibility In Vivo and Internal Fixation for Canine Femur Fractures

Bone plates have been applied to fix fractures for over a hundred years. Metal plates are the gold standard. However, an increasing number of clinical practices and animal experiments have shown that metal plates have had incidents of failure due to their rigid fixation and long‐term complications. Degradable composites present the advantages of a lower elastic modulus and absorbable properties but are unsuitable for load‐bearing applications. Nondegradable bone plates composed of a nanohydroxyapatite/polyamide 66/glass fiber (n‐HA/PA66/GF) composite are prepared, which have enough strength and a low elastic modulus for an internal fixation device. To better assess its function as a bone plate, animal experiments are conducted using a canine load‐bearing femur fracture model. The results show that the n‐HA/PA66/GF plate can fix fractures effectively. Gross observation, radiographic films, and histological analysis all show that the n‐HA/PA66/GF plate leads to a secondary (indirect) union with obvious callus formation, whereas the titanium plate leads to primary (direct) union due to rigid fixation. Furthermore, the histological results reveal that new bone grows at the interface and that the n‐HA/PA66/GF plate can integrate with native bone tissue. Consequently, the n‐HA/PA66/GF composite shows good potential as a bone plate to fix loading‐bearing bone fractures.
Comparative impact of bacitracin and select feed additives in the feeding program of Lohmann LSL-Lite pullets at the onset of lay through to 31 weeks of age

Abstract There are limited investigations on the role of feed additives in easing transition of pullets to egg production phase. We investigated the effects of supplementation of bacitracin methylene disalicylate (BMD) and select feed additives (myristic acid [MA], benzoic acid [BA], and Aspergillus niger probiotic [PRO]) in feeding program for pullets from the onset of lay through to 31 weeks of age (woa). Parameters measured included hen-day egg production (HDEP), feed intake (FI), feed conversion ratio (FCR), egg quality characteristics, ceca microbial activity, apparent retention of components, and plasma metabolites. A total of 1,200 Lohmann LSL Lite pullets were procured at 18 woa and placed in enriched cages (30 birds/cage) based on body weight (BW) and allocated to five diets. The diets were a basal diet formulated to meet specifications or basal mixed with either BMD, MA, BA, or PRO. Birds had free access to feed and water throughout the experiment. Between 18 and 20 woa, birds fed BMD ate a similar (P > 0.05) amount of feed to BA birds, but more (P = 0.0003) than birds fed basal, MA, or PRO diets. Basal birds had lower HDEP (P = 0.001) and lighter eggs (P < 0.0001) than birds fed any of the feed additives between 21 and 31 woa. The basal hens had a higher (P = 0.009) abundance of Escherichia coli than birds fed BMD, BA, and PRO diets. Consequently, BMD, BA, and PRO birds had a higher (P = 0.011) Lactobacilli: E. coli ratio (LER) than hens fed the basal diet. Specifically, relative to basal-fed hens, the LER of the BMD, MA, BA, and PRO hens was higher by 37%, 21%, 26%, and 45%, respectively. Moreover, birds fed PRO tended to have a higher concentration of ceca digesta acetic acid (P = 0.072) and a lower concentration of isobutyric acid (P = 0.096). In conclusion, supplementing pullet diets with broad-spectrum antibiotics or feed additives (MA, BA, and PRO) had a positive impact on FI, and egg production linked to modulation of indices of gut health. The results suggested supplementing feed additives in feeding programs for pullets at the onset of lay can bolster productivity outcomes.
Bacillus sp. G2112 Detoxifies Phenazine-1-carboxylic Acid by N5 Glucosylation

Microbial symbionts of plants constitute promising sources of biocontrol organisms to fight plant pathogens. Bacillus sp. G2112 and Pseudomonas sp. G124 isolated from cucumber (Cucumis sativus) leaves inhibited the plant pathogens Erwinia and Fusarium. When Bacillus sp. G2112 and Pseudomonas sp. G124 were co-cultivated, a red halo appeared around Bacillus sp. G2112 colonies. Metabolite profiling using liquid chromatography coupled to UV and mass spectrometry revealed that the antibiotic phenazine-1-carboxylic acid (PCA) released by Pseudomonas sp. G124 was transformed by Bacillus sp. G2112 to red pigments. In the presence of PCA (>40 µg/mL), Bacillus sp. G2112 could not grow. However, already-grown Bacillus sp. G2112 (OD600 > 1.0) survived PCA treatment, converting it to red pigments. These pigments were purified by reverse-phase chromatography, and identified by high-resolution mass spectrometry, NMR, and chemical degradation as unprecedented 5N-glucosylated phenazine derivatives: 7-imino-5N-(1′β-D-glucopyranosyl)-5,7-dihydrophenazine-1-carboxylic acid and 3-imino-5N-(1′β-D-glucopyranosyl)-3,5-dihydrophenazine-1-carboxylic acid. 3-imino-5N-(1′β-D-glucopyranosyl)-3,5-dihydrophenazine-1-carboxylic acid did not inhibit Bacillus sp. G2112, proving that the observed modification constitutes a resistance mechanism. The coexistence of microorganisms—especially under natural/field conditions—calls for such adaptations, such as PCA inactivation, but these can weaken the potential of the producing organism against pathogens and should be considered during the development of biocontrol strategies.
