Abstract
Contamination of soils with toxic metals poses significant threats to human health and ecosystems. Plant-based remediation strategies can play a vital role in mitigating these risks, and the use of plants as a remediation strategy can help reduce these risks. In this study, we investigate the remediation potential of native plants in accumulating and translocating metal(loid)s at a Colombian site impacted by gold mining. The remediation capacity is evaluated using the translocation factor (TF) from roots to shoots and the bioconcentration factor (BCF) from soil to roots. Metal(loid) concentrations in the soil followed the order: Fe > As > Hg > Cd > Pb > Zn > Mn > Cu. In plant tissues, Hg showed higher accumulation in leaves (3.5 mg/kg) compared to roots (2.8 mg/kg). Pb (17.7 mg/kg), As (3.8 mg/kg), Fe (2.5 mg/kg) and Cd (1.2 mg/kg) concentracions were also higher in roots. Metal concentrations in the stems, were generally below 1.0 mg/kg, except for Pb (15.0 mg/kg) and Hg (1.0 mg/kg). The highest BCF values for Hg were observed in Spondias mombin L. (18.7), Cecropia peltata L. (8.3) and Gliricidia sepium (Jacq.) Walp (4.4). On the other hand, Senna alata (L.) Roxb., Psidium guajava L. and Morinda citrifolia L. exhibited notable BFC values for As with 44.7, 6.3 and 5.9, respectively. Musa x paradisiaca L. had the highest BCF for Cd (1.8). M. citrifolia (4.3) and Annona muricata L. (3.2) exhibited the highest TF for Hg, while Tabebuia rosea (Bertol.) Bertero ex A.DC. (4.9) and Paspalum fasciculatum Willd. ex (3.1) demonstrated elevated TF values for Pb. In conclusion, plants such as P. fasciculatum, A. muricata, M. citrifolia, G. sepium and T. rosea exhibit great potential for application in phytoremediation strategies in tropical regions impacted by gold mining activities.

Published: January 2025

Abstract
In inverse optimization problems, we are given a feasible solution to an underlying optimization problem, and the goal is to modify the problem parameters so that the given input solution becomes optimal. In the minimum-cost setting, the underlying optimization problem is endowed with a linear cost function, and the goal is to modify the costs by a small deviation vector so that the input solution becomes optimal. The difference between the new and the original cost functions can be measured in several ways. In this paper, we focus on two objectives: the weighted bottleneck Hamming distance and the weighted

$$\ell _{\infty }$$

ℓ
∞

-norm. We consider a general model in which the coordinates of the deviation vector are required to fall within given lower and upper bounds. For the weighted bottleneck Hamming distance objective, we present a simple, purely combinatorial algorithm that determines an optimal deviation vector in strongly polynomial time. For the weighted

$$\ell _{\infty }$$

ℓ
∞

-norm objective, we give a min-max characterization for the optimal solution, and provide a pseudo-polynomial algorithm for finding an optimal deviation vector that runs in strongly polynomial time in the case of unit weights. For both objectives, we assume that an algorithm with the same time complexity for solving the underlying combinatorial optimization problem is available.

Abstract
Lung cancer patients generally receive several information regarding their illness characteristics and available intervention. Therefore, patients can experience confusion, leading to anxiety and distress that might damage the relationship with physicians and treatment adherence. Literature showed that implementing decision aid tools during consultation can promote patients’ knowledge and awareness about lung cancer and available oncological intervention, improving a shared decision-making process. However, not all lung cancer patients always appreciate decision aids’ implementation. The present qualitative study explored patients’ opinions and preferences regarding the implementation of decision aids during medical consultation. Twenty-two lung cancer patients who have already attended medical consultations for lung cancer voluntarily participated in four online focus groups carried out between January 2023 and December 2024. A thematic analysis with a bottom-up approach highlighted three main themes: the typology and number of information that patients would have received, the relevance of patient-and-doctor relationship, and the effects of providing additional decision-making tools on patients’ emotions and preferences. Findings showed controversial opinions among patients, highlighting the relevance of personalized intervention tailored to patients’ preferences. Practical implications are given.

Abstract

Background
Osteopenia (ON) and osteoporosis (OP) are highly prevalent among postmenopausal women and poses a challenge for early diagnosis. Therefore, identifying reliable biomarkers for early prediction using metabolomics is critically important.

Methods
Initially, non-targeted metabolomics was employed to identify differential metabolites in plasma samples from cohort 1, which included healthy controls (HC, n = 23), osteonecrosis (ON, n = 36), and osteoporosis (OP, n = 37). Subsequently, we performed targeted metabolomic validation of 37 amino acids and their derivatives in plasma samples from cohort 2, consisting of healthy controls (HC, n = 10), osteonecrosis (ON, n = 10), and osteoporosis (OP, n = 10).

Results
The non-targeted metabolomic analysis revealed an increase in differential metabolites with the progression of the disease, showing abnormalities in lipid and organic acid metabolism in ON and OP patients. Several substances were found to correlate positively or negatively with bone mineral density (BMD), for example, N-undecanoylglycine, sphingomyelins, and phosphatidylinositols exhibited positive correlations with BMD, while acetic acid, phenylalanine, taurine, inosine, and pyruvic acid showed negative correlations with BMD. Subsequently, targeted validation of 37 amino acids and their metabolites revealed six amino acids related to ON and OP.

Conclusion
Significant metabolomic features were identified between HC and patients with ON/OP, with multiple metabolites correlating positively or negatively with BMD. Integrating both targeted and non-targeted metabolomic results suggests that lipid, organic acid, and amino acid metabolism may represent important metabolomic characteristics of patients with OP, offering new insights into the development of metabolomic applications in OP.

Abstract

Purpose
The purpose of the study was to clarify the relevance of colloidal phosphorus (Pcoll) to total P (TP) leaching and its link to dissolved organic P (DOP) leaching in forest topsoils under field conditions. Effects of heavy rainfall after a drought and the influence of P and N inputs to forest soils on Pcoll leaching from the topsoil were assessed to better understand the causes of Pcoll leaching.

Methods
We carried out an irrigation experiment with zero-tension lysimeters collecting leachate from the organic forest floor layers and mineral topsoils of a sandy, low-P and a loamy, high-P soil.

Results
The contribution of Pcoll to TP concentrations was on average around 10±14% irrespective of sampling date, season and soil. The highest Pcoll concentrations were recorded upon irrigation after a summer dry period with the increase in concentrations being most pronounced for the 20–70 nm size fraction with low median C:P ratios (29 to 31) typical for microbial residues. Significant relationships between Pcoll and DOP concentrations suggested that 27% (low P soil) and 17% (high P soil) of DOP were of colloidal nature. Independent of the soil P stock, the addition of P and P + N affected neither Pcoll concentrations nor their share of TP significantly.

Conclusion
While Pcoll hardly affected the overall estimates of beech forest P budgets, it provides important further insights into processes governing the mobilization, transport, and cycling of P in forest ecosystems.
Mass extinctions and their rebounds: a macroevolutionary framework
Authors: Jablonski David , Edie Stewart M. 
Published: January 2025

Abstract
Mass extinctions are natural experiments on the short- and long-term consequences of pushing biotas past breaking points, often with lasting effects on the structure and function of biodiversity. General properties of mass extinctions—exceptionally severe, taxonomically broad, global losses of taxa—are starting to come into focus through comparisons among dimensions of biodiversity, including morphological, functional, and phylogenetic diversity. Notably, functional diversity tends to persist despite severe losses of taxonomic diversity, whereas taxic and morphological losses may or may not be coupled. One of the biggest challenges in synthesizing and extracting general consequences of these events has been that they are often driven by multiple, interacting pressures, and the taxa and their traits vary among events, making it difficult to link single stressors to specific traits. Ongoing improvements in the taxonomic and stratigraphic resolution of these events for multiple clades will sharpen tests for selectivity and help to isolate hitchhiking effects, whereby organismal traits are carried by differential survival or extinction of taxa owing to other organismal or higher-level attributes, such as geographic-range size. Direct comparative analyses across multiple extinction events will also clarify the impacts of particular drivers on taxa, functional traits, and morphologies. It is not just the extinction filter that deserves attention, as the longer-term impact of extinctions derives in part from their ensuing rebounds. More work is needed to uncover the biotic and abiotic circumstances that spur some clades into re-diversification while relegating others to marginal shares of biodiversity. Combined insights from mass extinction filters and their rebounds bring a macroevolutionary view to approaching the biodiversity crisis in the Anthropocene, helping to pinpoint the clades, functional groups, and morphologies most vulnerable to extinction and failed rebounds.
From organisms to biodiversity: the ecology of the Ediacaran/Cambrian transition
Authors: Mitchell Emily G. , Pates Stephen 
Published: January 2025

Abstract
The Ediacaran/Cambrian transition (ECT; ~575–500 Ma) captures the early diversification of animals, including the oldest crown-group taxa of most major animal phyla alive today. Key to understanding the drivers underneath the ECT macroevolutionary patterns are the interactions of animals with one another and their environment, and how these interactions scale up to global diversity patterns. Understanding the ecology of ECT organisms is enabled by the abundance of Lagerstätten over this time period, with a relatively large proportion of soft-bodied organisms preserved, often within the communities in which they lived. Here, we review our understanding of organismal, community, and macroecology of the ECT, and how these different scales of ecological analyses relate to the macroevolutionary diversification patterns we see over this 75 Myr time period. Across all ecological scales, we find clear trends, starting with stochastic ecosystem dynamics dominated by generalist taxa in the first Ediacaran communities, to more structured, niche-driven specialist dynamics by Cambrian Epoch 2. These trends are reflected in organism functional morphology, the complexity and strength of organisms’ interactions within their communities, and large-scale metacommunity, biogeographic, and biodiversity patterns. Yet there is often a time delay between the origination of a new type of ecological interaction and when it is observed to impact the ecosystem as a whole. As such, while many modern ecological innovations were in place by the end of the Cambrian, the knock-on effects and complexity of these interactions continued to build up throughout the Phanerozoic, leading to the complex biosphere we have today.
Angle and Polarization Insensitive RCS Reduction Metasurface Based on Hybrid Mechanism of Polarization Conversion and Absorption

Published: January 2025

AbstractThis article introduces the concept, theory, and design of an angle and polarization insensitive radar cross section (RCS) reduction metasurface, using a hybrid mechanism of polarization conversion and absorption. By introducing ladder‐ and rectangle‐shaped metallic patches in the vertical dimension of a 3‐D structure, polarization conversion rate (PCR) deterioration, brought by the increase of equivalent substrate thickness at oblique incidences, can be suppressed. Furthermore, lumped resistors are loaded at proper places in each polarization conversion cell, to achieve the power absorption while maintain the angular insensitivity of the PCR. With the above hybrid mechanism, a stable 10‐dB RCS reduction can be achieved regardless of the angle of incidence in a wide range and polarization directions. An equivalent circuit model is established for explaining the physical mechanism of the proposed metasurface. For validation, a prototype is fabricated and tested. Measurement results indicate that, for both monostatic RCS at the normal incidence and specular RCS of off‐normal incidences from 0° to 45°, a 10‐dB TE‐ and TM‐mode RCS reduction can be achieved in the entire X‐band (8–12 GHz) and Ku‐band (12–18 GHz).

Abstract
Female obesity is a worldwide health issue linked to chronic metabolic low-grade inflammation (metaflammation) causing multiple obesity-related co-morbid conditions. We aimed to assess the serum levels of wingless integration site family member 5 A (Wnt5a), leptin, and tumor necrosis factor-alpha (TNF-α) as markers of obesity-associated metaflammation and investigate the association with toll-like receptors2 (TLR2) gene (Arg753Gln) single nucleotide polymorphism (SNP) among Egyptian females. The study included 60 females with obesity and 30 matched controls. Serum levels of Wnt5a, leptin, and TNF-α were assessed by ELISA, while TLR2 (Arg753Gln) genotyping was done by PCR-RFLP. Serum Wnt5a, leptin, and TNF-α showed significantly higher levels in females with obesity than controls and a significant increase with higher classes of obesity. They showed significant positive correlations with each other. Only TNF-α and leptin were associated with metabolic syndrome (MetS) among the obesity group. According to TLR2 (Arg753Gln) SNP, the homozygous GG genotype was associated with elevated levels of Wnt5a, leptin, and TNF-α compared to the AA + GA model carriers. No significant differences were found in the distribution of TLR2 Arg753Gln (rs5743708) genotypes and alleles according to obesity or MetS, and the regression analysis showed no significant risk association. Serum Wnt5a, leptin, and TNF-α levels increase in women with obesity and the A allele of TLR2 (Arg753Gln) SNP could be protective against obesity-associated metaflammation.

Abstract
To investigate the feasibility and clinical efficacy of a novel approach to managing the incisions used to treat tibial plateau fractures (TPFs) with soft tissue swelling. We retrospectively enrolled 64 patients with TPFs who underwent surgery at the Second Hospital of Shandong University. Patients were divided into two groups: Group A (n = 32) underwent early surgery with the novel incision management technique, and Group B (n = 32) underwent conventional surgery after swelling reduction. The perioperative data of the two groups were compared, including the time from injury to surgery, one-stage operation time, intraoperative blood loss, number of dressing changes, wound healing time, and hospitalization time. Preoperative and postoperative complications were assessed in both groups, and pain condition, degree of arthritis, limb function, imaging results, and quality of life were evaluated using validated scales. The time from injury to surgery, number of dressing changes, and hospitalization time in Group A were significantly lower than those in Group B (P < 0.05). There were no significant differences in one-stage operation time, intraoperative blood loss, or wound healing time between the two groups (P > 0.05). There were fewer preoperative and postoperative complications in Group A than in Group B (P < 0.05). The VAS and WOMAC scores were reduced in both groups (P < 0.05); Group A had lower VAS scores two weeks after surgery. There was no statistically significant difference in the WOMAC score between the groups. The modified Rasmussen functional and radiological scores were elevated in both groups (P < 0.05). There was no statistically significant difference between the two groups for the modified Rasmussen functional or radiological score at any of the time points (P > 0.05). In addition, the two groups did not differ in quality of life (P > 0.05). For patients with tibial plateau fractures without congestive blisters, open reduction and internal fixation at the early stage of swelling and wide-spacing interrupted suture and negative pressure wound therapy (NPWT) closure of the wound could help obtain excellent to good functional outcomes with fewer complications. This novel incision management approach and concept expands the surgical indications for these fractures.

Abstract
This study investigates the deposition of tantalum (Ta) coatings on carbon foams using the chemical vapor deposition (CVD) method to enhance their compressive strength. Two types of open-cell carbon foams, CF-1 and CF-2, with different strut diameters, were examined. The morphology and uniformity of the coatings were characterized, and the effect of coating thickness on the compressive strength of the foams was systematically analyzed. An empirical model was proposed and successfully validated, showing that the compressive strength is proportional to the coating thickness and the square of the strut diameter. The experimental results demonstrate that considering mass transfer and reaction kinetics can significantly improve the uniformity of coatings on larger substrates. Furthermore, the Ta coatings significantly increased the compressive strength of the foams, with the relationship between compressive strength, coating thickness, and strut diameter being in good agreement with the predictions of the proposed model. The study highlights the potential of tailored metallic coatings to enhance the mechanical properties of porous materials while maintaining their lightweight characteristics, emphasizing the importance of optimizing coating parameters for large-scale applications.

Published: January 2025

Abstract
Most studies on dogs’ olfactory performance focused only on some individuals pre-trained for a task or on specially selected/trained detection dogs. Here, using the Natural Detection Task (NDT) that does not require training, we assessed the effect of several potential factors on the performance of a large sample of dogs (N = 527/tested, 484/analysed). Olfactory success was associated with breeds, but breed groups (selected for olfaction, cooperation, or both) were proven non-relevant, suggesting that breed-specific traits are more influential than functional breed group characteristics. Border collies, selected for herding, reached higher success levels than golden retrievers, Hungarian/German vizslas and basset/bloodhounds, selected for hunting/olfaction tasks. Beagles found the hidden food quicker than border collies, basset/bloodhounds, golden retrievers, Labradors, and cocker spaniels. Dogs with higher Responsiveness to training personality scores were more successful, while higher training level linked to slower successful search. Activity/Excitability scores, attention-deficit/hyperactivity disorder scores, and owners’ rewarding style were not associated with performance. Overall, large within-breed/breed-group variabilities reflect complex interactions between genetic and environmental factors influencing performance. Given the complex nature of life-like detection tasks, the NDT may provide more information about dogs’ olfactory ability than on their potential effectiveness in detection work.
