Incongruent dissolution of silicates and its impact on the environment: an example of a talc mine
Authors: Kicińska Alicja , Pomykała Radosław 
Published: December 2023

AbstractThe paper analyzes the process of incongruent dissolution of silicates taking place in close proximity to a talc mine. The chemical and phase composition as well as the concentrations and mobility of potentially toxic elements (PTE) in research material with varying levels of weathering were determined using instrumental (XRF, XRD) and chemical methods (extractions: BCR, aqua regia, water leaching, 0.05 M EDTA). It was demonstrated that the predominant minerals in the weathering crust include weathering-resistant minerals (i.e. quartz and muscovite) and secondary minerals (kaolinite, illite and interstratified minerals, vermiculite/chlorite) and that the predominant processes are hydrolysis and oxidation. The weathering process has an impact on the complexity of the chemical and mineral composition and the diverse structure of the weathering crust. A layer of Fe and Al oxides and hydroxides forms in the upper part of the weathering crust, while the amount of silica decreases. Low-mobility elements (i.e. Si, Al and Fe) react on the phase separation surface, causing the formation of clay minerals (i.e. vermiculite, montmorillonite) or Al and Fe hydroxides (e.g. goethite). The duration of weathering causes an increase in the content of PTEs in solid materials: multifold in the case of Cr (15), Ba (9), Pb (7), Zn (6) and considerably lower in the case of V (1.3), Sr (0.8) and Co (0.4). It was demonstrated that PTEs co-occur in several chemical fractions in the weathering crust and that the highest share of their total concentration are cations incorporated in the crystal lattice of minerals and bound by strong crystalline bonds (F4 46%). The lowest share was observed for the reducible fraction (9%) and the share of the oxidizable fraction was 29% The most mobile cations connected by the weakest bonds comprised only 16% of the total concentration. Based on the content of the readily soluble fraction of PTEs, it was concluded that the degree of weathering does not increase the environmental risk, but actually reduces it for Cr, Cr and Pb. The obtained Ecological Risk Index (ERI) values indicate that the ecological risk associated with the elements tested is low for the entire area, which means that natural weathering processes do not have any impact on environmental pollution.

Abstract
Human glutamate carboxypeptidase 2 (GCP2) from the M28B metalloprotease group is an important target for therapy in neurological disorders and an established tumor marker. However, its physiological functions remain unclear. To better understand general roles, we used the model organism Caenorhabditis elegans to genetically manipulate its three existing orthologous genes and evaluate the impact on worm physiology. The results of gene knockout studies showed that C. elegans GCP2 orthologs affect the pharyngeal physiology, reproduction, and structural integrity of the organism. Promoter-driven GFP expression revealed distinct localization for each of the three gene paralogs, with gcp-2.1 being most abundant in muscles, intestine, and pharyngeal interneurons, gcp-2.2 restricted to the phasmid neurons, and gcp-2.3 located in the excretory cell. The present study provides new insight into the unique phenotypic effects of GCP2 gene knockouts in C. elegans, and the specific tissue localizations. We believe that elucidation of particular roles in a non-mammalian organism can help to explain important questions linked to physiology of this protease group and in extension to human GCP2 involvement in pathophysiological processes.
Polarization microwave correlation imaging method based on orthogonal complement space
Authors: Tian Runkun , Dai Dahai , Ji Penghui , Pang Bo , Sun Shilong 
Published: December 2023

AbstractCurrently, microwave correlation imaging (MCI) is regarded as an important method to address the forward‐looking imaging problem in radar. The key step of this method is to form a spatio‐temporal two‐dimensional random radiation field through various means. However, the current methods do not consider the polarization domain, which is an important dimension of electromagnetic signals. The existing research mainly focuses on using polarized antenna elements, without incorporating polarization information into the imaging system. To fill this gap, this letter proposes the polarization microwave correlation imaging (PMCI) based on the orthogonal complement space, which performs instantaneous polarization measurements (IPM) while correlating imaging of the target. Through simulation analysis, this method can further improve the quality and anti‐interference ability of MCI. Moreover, under the condition of low time‐frequency product, the peak sidelobe level (PSL) and isolation of this method are approximately 3.5 dB and 12.5 dB higher than those of traditional instantaneous polarization measurement methods (TIPM).

AbstractIn the present market scenario, energy cost has been increased and also restrictions have been faced in fossil fuels energy sources. This leads to evolvement of combined heat and power generating units having higher efficiency as compared to the existing systems. The optimal dispatch of CGUs involves a number of intricate constraints, making it a practical optimization problem. So, an improved heap‐based optimizer algorithm has been implemented in this work for solving optimal dispatch problem by accomplishing a proper balance between initial and final stages of global search and convergence, respectively. This problem provides optimal scheduling of heat and power generating units and seeks to minimize the overall fuel cost supply of combined units considering their operational limits. Here, three test systems, that is, 7‐units, 24‐units and 48 units system have been taken into consideration to verify the performance of proposed IHBO algorithm. The impact of prohibited zones on power dispatch has been analysed for both the system in an electricity market. In addition, the valve‐point loading effect, mutual dependency of produced heat and power of combined units and also transmission power losses in transmission lines have been studied. Comparisons among different methods have been made based on their respective solutions obtained and from that it manifests the robustness and superior performance of the proposed technique. Verification studies showed that impact of prohibited zones on generating units, increases the production cost with respect to without prohibited zones. However the proposed technique yields least production cost among other techniques.

Context. One of the most prominent sources for energetic particles in our Solar System are huge eruptions of magnetised plasma from the Sun, known as coronal mass ejections (CMEs), which usually drive shocks that accelerate charged particles up to relativistic energies. In particular, energetic electron beams can generate radio bursts through the plasma emission mechanism, for example, type II and accompanying herringbone bursts.
Aims. In this work, we investigate the acceleration location, escape, and propagation directions of various electron beams in the solar corona and compare them to the arrival of electrons at spacecraft.
Methods. To track energetic electron beams, we used a synthesis of remote and direct observations combined with coronal modeling. Remote observations include ground-based radio observations from the Nançay Radioheliograph (NRH) combined with space-based extreme-ultraviolet and white-light observations from Solar Dynamics Observatory (SDO), Solar Terrestrial Relations Observatory (STEREO), and Solar Orbiter (SolO). We also used direct observations of energetic electrons from the STEREO and Wind spacecraft. These observations were then combined with a three-dimensional (3D) representation of the electron acceleration locations, including the results of magneto-hydrodynamic models of the solar corona. This representation was subsequently used to investigate the origin of electrons observed remotely at the Sun and their link to in situ electrons.
Results. We observed a type II radio burst followed by herringbone bursts that show single-frequency movement through time in NRH images. The movement of the type II burst and herringbone radio sources seems to be influenced by regions in the corona where the CME is more capable of driving a shock. We found two clear distinct regions where electrons are accelerated in the low corona and we found spectral differences between the radio emission generated in these regions. We also found similar inferred injection times of near-relativistic electrons at spacecraft to the emission time of the type II and herringbone bursts. However, only the herringbone bursts propagate in a direction where the shock encounters open magnetic field lines that are likely to be magnetically connected to the same spacecraft.
Conclusions. Our results indicate that if the in situ electrons are indeed shock-accelerated, the most likely origin of the in situ electrons arriving first is located near the acceleration site of herringbone electrons. This is the only region during the early evolution of the shock where there is clear evidence of electron acceleration and an intersection of the shock with open field lines, which can be directly connected to the observing spacecraft.

Context. The global context of making numerous data produced by researchers available requires collecting and organising the data, assigning meaningful metadata, and presenting the data in a meaningful and homogeneous way. The BASECOL database, which collects inelastic rate coefficients for application to the interstellar medium and to circumstellar and cometary atmospheres, meets those requirements.
Aims. We aim to present the scientific content of the BASECOL2023 edition.
Methods. While the previous versions relied on finding rate coefficients in the literature, the current version is populated with published results sent by the producers of data. The paper presents the database, the type of data that can be found, the type of metadata that are used, and the Virtual Atomic and Molecular Data Centre (VAMDC) standards that are used for the metadata. Finally, we present the different datasets species by species.
Results. As the BASECOL database, interconnected with the VAMDC e-infrastructure, uses the VAMDC standards, the collisional data can be extracted with tools using VAMDC standards and can be associated with spectroscopic data extracted from other VAMDC connected databases such as the Cologne database for molecular spectroscopy (CDMS), the jet propulsion laboratory molecular spectroscopy database (JPL), and the high-resolution transmission molecular absorption database (HITRAN).
Oil palm plantation systems are at a crossroads
Authors: Rival Alain , Chalil Diana 
Published: December 2023

The future of most tropical sectors is clouded by growing constraints linked to, among many other parameters, climate change, price volatility and labour scarcity. Perpetuating agricultural systems inherited from the colonial era (a time of abundant arable land, protected markets, and cheap and disciplined labour) will not be enough to prepare these sectors in facing immediate crucial challenges unless substantial structural transformations are made.
Implementing a successful agroecological transition in a 70-billion USD sector, covering 25 million ha worldwide, calls for drastic changes in mind-sets and practices. The key issue is no longer simply to increase productivity, but to foster innovations designed to support endangered tropical biodiversity, while providing a decent living for shrinking agricultural communities in the Global South.
Agroforestry practices have a role to play in providing substantial climate change mitigation with an impact comparable to other climate-focused solutions, such as reforestation. The expected contribution of oil palm-based agroforestry relies on agro-environmental services, as basic agricultural functions such as soil preservation, pollination, or pest control can be ensured by living organisms inside and around the plantation. Diversified systems are able to achieve both economic and environmental gains, as they use land more efficiently than monocultures. Building on regenerative agriculture, new plantation designs are emerging and deserve to be thoroughly assessed to establish evidence-based advocacy for change.
Potenzielle Chancen und Herausforderungen des neuen
interdisziplinären Schwerpunkts Ernährungsmedizin in der
Schweiz
Authors: Gyger Angela , Tribolet Pascal 
Published: December 2023

Zusammenfassung
Einleitung Die Ernährung hat heutzutage aus verschiedenen
Gründen einen hohen Stellenwert, weshalb die wissenschaftlich fundierte
Ernährungsmedizin gefördert werden sollte. Deshalb wurde von der
Gesellschaft für Ernährungsmedizin und Metabolismus Schweiz
(GESKES) der neue interdisziplinäre Schwerpunkt
Ernährungsmedizin geschaffen. Welche Praxiserfahrungen konnten bisher
gesammelt werden? Was sind Wünsche bezüglich der
interprofessionellen Zusammenarbeit? Welche Chancen und Herausforderungen
bestehen durch den neuen Titel? Diesen Fragen wurde im Rahmen einer
Bachelor-Thesis nachgegangen.
Methodik Mittels qualitativer Forschungsmethode wurden sechs
halbstandardisierte Einzelinterviews mit je drei Personen der
Ernährungsberatung und Ernährungsmedizin aus insgesamt drei
Deutschschweizer Spitälern durchgeführt.
Ergebnisse Beide Berufsgruppen erachten insbesondere die Steigerung von
Ernährungskompetenzen seitens Ärzteschaft als Chance des
Schwerpunkttitels, um die Behandlungsqualität zu optimieren. Zudem
bietet der Titel die Möglichkeit, der Ernährung mehr Anerkennung
zu verschaffen. Als wesentliche Herausforderungen des Schwerpunkts gelten die
Implementierung der Ernährungsmedizin, welche in den Institutionen
individuell geregelt wird und die Befürchtung von Kompetenzverlusten.
Beide Berufsgruppen wünschen sich in Zukunft geregelte Prozesse und
einen Austausch in übergeordneten Gremien der Schweiz, um gemeinsam den
Einsatz des Titels weiterzuentwickeln.
Schlussfolgerung Der interdisziplinäre Schwerpunkt ist bis anhin
sowohl bei der Berufsgruppe der Ernährungsberatung als auch bei der
Ernährungsmedizin weitgehend auf positive Resonanz gestossen und scheint
zu einer Stärkung des Stellenwerts der Ernährung beizutragen.
Grossflächigere Erhebungen sind notwendig, um weitere Erfahrungen von
Institutionen zu erfassen und darauf ausgerichtet Prozessabläufe
auszuarbeiten sowie konkrete Empfehlungen bezüglich der Implementierung
des Titels abzugeben.
Standardized vs. Relative Intensity in CrossFit
Authors: Oliver-López Alejandro , García-Valverde Adrián , Sabido Rafael 
Published: December 2023

AbstractCrossFit is characterized by being a standardized training program that improves
physical performance through the provision of several stimuli regardless of the
participant’s strength level. This study aimed to compare the acute
response in total repetitions as a measurement of performance, jump ability,
physiological demand (heart rate and blood lactate), and perceived effort
considering the participants’ strength level with individualized
intensity in CrossFit. Thirty-five participants were assessed and asked to
participate on two separate days in a standardized and relative ‘As Many
Repetitions As Possible’ (AMRAP) CrossFit circuit. Both AMRAPs comprised
strength, gymnastic and aerobic exercises, although only strength was
individualized according to the participant’s level. Before the
statistical analysis, participants were allocated to higher- or lower-strength
groups following the one-repetition maximum-bodyweight ratio in the push press
exercise. Results support the existence of a strong relationship between
strength level and total repetitions in both AMRAPs. In addition, differences in
total repetitions and rate of perceived exertion between strength groups are
discarded when AMRAP intensity is individualized while physiological demand and
jump ability are maintained. Thus, the higher-strength participants may benefit
from similar responses with a lower number of repetitions. Therefore, CrossFit
trainers should be encouraged to prescribe strength tasks based on the
percentage of 1RM for every training.

Authors: Gopakumar Harishankar , Khan Hamza , Sharma Neil , Puli Srinivas Reddy 
Published: December 2023

Abstract
Background and study aims Endoscopically delivered liquid nitrogen spray cryotherapy is reported to be a safe and possibly more effective strategy for dysphagia palliation in patients with advanced esophageal cancer. This systematic review and meta-analysis aimed to pool all available data to evaluate the impact of this treatment modality.
Methods Electronic databases (PubMed, Embase, and Cochrane Library) from January 2005 through June 2023 were searched for studies evaluating endoscopically delivered liquid nitrogen spray cryotherapy for dysphagia palliation in patients with advanced esophageal cancer. Pooled proportions were calculated using random-effects (DerSimonian-Laird) model.
Results From an initial 895 studies, data were extracted and analyzed from five studies comprising a total of 230 patients that met inclusion criteria. In this pooled analysis, dysphagia improved or did not deteriorate in 81.40% of patients (95% confidence interval [CI] 73.75–87.99). Significant improvement in dysphagia was reported by 55.19% of patients (95% CI 29.62–79.37). An alternate method of dysphagia palliation despite spray cryotherapy was required in 18.78% of patients (95% CI 8.09–32.63) with 10.56% (95% CI 2.53–23.18) requiring esophageal stents. The weighted mean number of spray cryotherapy sessions per patient was 3.37 (95% CI 2.55–4.18). The pooled major adverse event rate was 3.26% (95% CI 0.15–10.14).
Conclusions Endoscopic liquid nitrogen spray cryotherapy can effectively and safely treat dysphagia in esophageal cancer. It can be considered an option for dysphagia palliation in centers with expertise and equipment.
Low Molecular Weight Supramolecular Allobetuline-, Cyclohexanol-, or Undecanol-Appended 1,2,3-Triazole-Based Gelators: Synthesis and Molecular Dynamics Simulation Study

Published: December 2023

AbstractThree novel isomeric supramolecular allobetuline-appended 1,2,3-triazole-based potential gelators and two model compounds with cyclohexanol or undecanol fragments in the structure instead of the triterpenoid platform were synthesized. Their ability to form gels in different solvents was studied experimentally and computationally by molecular dynamics simulations and quantum chemical calculations. We found that the gelling ability of such compounds is driven by the binding energy of intermolecular tail substituent interactions. The less significant factor is the molecule unfolding in a solvent, providing that the gelling substance is actually soluble. Preferred unfolded conformations were identified by classical molecular dynamics simulation and suggested the most prospective 1,2,3-triazole-based potential gelators.
Circulating Cytokines and Venous Thromboembolism: A Bidirectional Two-Sample Mendelian Randomization Study
Authors: Hu Teng , Su Pengpeng , Yang Fangkun , Ying Jiajun , Chen Yu , Cui Hanbin 
Published: December 2023

Background Epidemiological evidence has linked circulating cytokines to venous thromboembolism (VTE). However, it remains uncertain whether these associations are causal due to confounding factors or reverse causality. We aim to explore the causality between circulating cytokines and VTE, encompassing deep vein thrombosis (DVT) and pulmonary embolism (PE).
Methods In the current bidirectional Mendelian randomization (MR) study, instrumental variables of 41 circulating cytokines were obtained from the genome-wide association study meta-analyses (8,293 individuals). Summary statistics for the association of VTE (17,048 cases and 325,451 controls), DVT (8,077 cases and 295,014 controls), and PE (8,170 cases and 333,487 controls) were extracted from the FinnGen Study. A multivariable MR study was conducted to adjust for potential confounders. The inverse-variance weighted method was employed as the main analysis, and comprehensive sensitivity analyses were conducted in the supplementary analyses.
Results The MR analysis indicated stromal cell-derived factor-1α was suggestively associated with a reduced risk of VTE (odds ratio [OR]: 0.90; 95% confidence interval [CI]: 0.81–0.99; p = 0.033) and DVT (OR: 0.85; 95% CI: 0.75–0.97; p = 0.015). In addition, suggestive association of granulocyte colony-stimulating factor with PE (OR: 1.20; 95% CI: 1.06-1.37; p = 0.005) was observed. Multivariable MR analysis showed that the effect of cytokines on VTE was partly mediated through hemoglobin A1c and systolic blood pressure. Reverse MR analysis revealed that VTE was linked to decreased levels of several cytokines.
Conclusion We provide suggestive genetic evidence supporting the bidirectional causal effect between circulating cytokines and VTE, highlighting the importance of targeting circulating cytokines to reduce the incidence of VTE.
