Published: September 2022

AbstractThis work deals with the consequences of climate warming on aquatic ecosystems. The study determined the effects of increased water temperatures in artificial lakes during winter on predicting changes in the biomass of zooplankton taxa and their environment. We applied an innovative approach to investigate the effects of winter warming on zooplankton and physico-chemical factors. We used a modelling scheme combining hierarchical clustering, eXtreme Gradient Boosting (XGBoost) and SHapley Additive exPlanations (SHAP) algorithms. Under the influence of increased water temperatures in winter, weight- and frequency-dominant Crustacea taxa such as Daphnia cucullata, Cyclops vicinus, Cryptocyclops bicolor, copepodites and nauplii, and the Rotifera: Polyarthra longiremis, Trichocerca pusilla, Keratella quadrata, Asplanchna priodonta and Synchaeta spp. tend to decrease their biomass. Under the same conditions, Rotifera: Lecane spp., Monommata maculata, Testudinella patina, Notholca squamula, Colurella colurus, Trichocerca intermedia and the protozoan species Centropyxis acuelata and Arcella discoides with lower size and abundance responded with an increase in biomass. Decreases in chlorophyll a, suspended solids and total nitrogen were predicted due to winter warming. Machine learning ensemble models used in innovative ways can contribute to the research utility of studies on the response of ecological units to environmental change.

Published: September 2022

AbstractThe binocular stereo vision is the lowest cost sensor for obtaining 3D information. Considering the weakness of long‐distance measurement and stability, the improvement of accuracy and stability of stereo vision is urgently required for application of precision agriculture. To address the challenges of stereo vision long‐distance measurement and stable perception without hardware upgrade, inspired by hawk eyes, higher resolution perception and the adaptive HDR (High Dynamic Range) were introduced in this paper. Simulating the function from physiological structure of ‘deep fovea’ and ‘shallow fovea’ of hawk eye, the higher resolution reconstruction method in this paper was aimed at accuracy improving. Inspired by adjustment of pupils, the adaptive HDR method was proposed for high dynamic range optimisation and stable perception. In various light conditions, compared with default stereo vision, the accuracy of proposed algorithm was improved by 28.0% evaluated by error ratio, and the stability was improved by 26.56% by disparity accuracy. For fixed distance measurement, the maximum improvement was 78.6% by standard deviation. Based on the hawk‐eye‐inspired perception algorithm, the point cloud of orchard was improved both in quality and quantity. The hawk‐eye‐inspired perception algorithm contributed great advance in binocular 3D point cloud reconstruction in orchard navigation map.

Published: September 2022

AbstractA novel circularly polarized (CP) substrate integrated magneto‐electric dipole (MED) antenna has been designed for appropriate wireless communication. The antenna comprises two printed radiating arc‐shaped patches and a feeding strip on top, two rows of embedded metallic vias, and a ground plane. A coax probe is used to excite the patches and via rows simultaneously with the help of a printed feeding strip. Finally, the antenna design has been prototyped and its performance experimentally was verified in terms of impedance bandwidth, axial‐ratio (AR), gain, efficiency, and radiation patterns. The measured impedance bandwidth (under −10 dB) and AR bandwidth (under 3 dB) are 6.15–7.01 (13%) GHz and 6.24–6.40 (2.53%) GHz respectively. Typically, the measured gain value within 3‐dB AR bandwidth at 6.3 GHz is 4.5 dBic with average measured in‐band antenna efficiency of 85.2%. Moreover, the proposed antenna shows an acceptable agreement with predicted counterparts, including unidirectional radiation patterns.

Published: September 2022

AbstractGiven the advancements in solar power generation and fifth‐generation (5G) technologies, it is crucial to reduce energy consumption based on accurate predictions of the photovoltaic power requirements of 5G base stations (BSs) connected to renewable energy sources. To ensure sufficient prediction performance even under complex weather conditions and promote two‐way flow of energy and information in the power supply system of the 5G BS, this work first proposes a reference scenario for a 5G BS with an energy router. Then, the comprehensive grey relational analysis is used to determine the optimal photovoltaic input variables. Finally, the improved logistic distribution, Laplacian distribution with inverse incomplete gamma‐function weight factor, and nonlinear mutation perturbation strategy are introduced to improve the ability of the sparrow search algorithm to avoid locally optimal solutions for an extreme learning machine of the short‐term photovoltaic power prediction model. The proposed model is applied to actual measured data for validation, and the results show that this model has the lowest mean percentage error as well as highest prediction accuracy under different weather conditions. The coefficient of determination for the proposed prediction model is greater than 99%; therefore, it is expected to improve the photovoltaic prediction performances of 5G energy‐routing BSs as well as promote sustainable development and sharing of energy and information.

Published: September 2022

Aims. We present a new prediction for the luminosity functions (LFs) of the [C II] line at 158 μm, of the CO lines from J = 0 to J = 24, and of the molecular gas mass density up to z = 10, using the Spectro-Photometric Realisations of Infrared-selected Targets at all-z (SPRITZ) simulation.
Methods. We update the state-of-the-art phenomenological simulation SPRITZ to include both the CO (J ≤ 24) and the [C II] line luminosities. This has been performed using different empirical and theoretical relations to convert the total infrared luminosity (or star formation rate, SFR) to the [C II] or CO luminosity. The resulting line LFs were compared for validation with a large set of observations available in the literature. We then used the derived CO and [C II] line luminosities to estimate the molecular gas mass density and compare it with available observations.
Results. The CO and [C II] LFs presented here are in good agreement with all the available observations. In particular, the best results for [C II] are obtained deriving the [C II] luminosity directly from the SFR, but considering a dependence of this relation on the gas metallicity. For all the CO LFs, the estimates favoured by the data are derived considering different relations, depending on the ionisation mechanism dominating each galaxy, namely star formation or active galactic nuclei, and, moreover, by deriving the J ≥ 4 CO lines directly from the [C II] luminosity. However, further data are necessary to fully distinguish between models. Finally, the best agreements with observations of the molecular gas mass density are derived by converting the [C II] luminosity to H2 mass, using a [C II]-to-H2 conversion ∼130 M⊙/L⊙. All the line LFs, useful for planning and interpreting future observations, are made publicly available.

Aims. With the aim of finding microlensing binaries containing brown dwarf (BD) companions, we investigate the microlensing survey data collected during the 2016–2018 seasons.
Methods. For this purpose, we first modeled lensing events with light curves exhibiting anomaly features that are likely to be produced by binary lenses. We then sorted out BD companion binary-lens events by applying the criterion that the companion-to-primary mass ratio is q ≲ 0.1. With this procedure, we identify six binaries with candidate BD companions: OGLE-2016-BLG-0890L, MOA-2017-BLG-477L, OGLE-2017-BLG-0614L, KMT-2018-BLG-0357L, OGLE-2018-BLG-1489L, and OGLE-2018-BLG-0360L.
Results. We estimated the masses of the binary companions by conducting Bayesian analyses using the observables of the individual lensing events. According to the Bayesian estimation of the lens masses, the probabilities for the lens companions of the events OGLE-2016-BLG-0890, OGLE-2017-BLG-0614, OGLE-2018-BLG-1489, and OGLE-2018-BLG-0360 to be in the BD mass regime are very high with PBD > 80%. For MOA-2017-BLG-477 and KMT-2018-BLG-0357, the probabilities are relatively low with PBD = 61% and 69%, respectively.
Constraining leptonic emission scenarios for the PeVatron candidate HESS J1702−420 with deep XMM-Newton observations

Published: September 2022

Aims. We aim to search for a hidden leptonic accelerator, such as a high-Ė pulsar, associated with the unidentified TeV object HESS J1702−420A.
Methods. We carried out a 72 ks X-ray observation with the XMM-Newton satellite and analyzed the resulting data jointly with the publicly available HESS spectral energy distribution (SED) results to derive constraints on the leptonic contribution to the TeV emission of HESS J1702−420A. A set of scripts dedicated to the multi-wavelength modeling of X-ray and γ-ray data, based on Gammapy, Naima, and Xspec, has been developed in the context of this work and made publicly available along with this paper.
Results. No object clearly associated with HESS J1702−420A was found in the XMM-Newton data. After excluding the unidentified object Suzaku src B as a possible X-ray counterpart and classifying it as a new cataclysmic variable source candidate, we derived strict upper limits on the level of diffuse X-ray emission in the HESS J1702−420A region: F(2 − 10 keV)≲5.4  × 10−5 keV  cm−2 s−1 at 2σ (≈95.5%) confidence level. A tight constraint on the magnetic field was derived, under a one-zone leptonic scenario, by jointly fitting the XMM-Newton spectra and the HESS SED: B ≲ 1.45 μG at 2σ level. We additionally report the serendipitous discovery of a new extended X-ray source with a hard spectral index of 1.99 ± 0.45, named XMMU J170147.3−421407 which is likely Galactic. Its classification as a high-speed runaway pulsar wind nebula (PWN), possibly associated with HESS J1702−420A, is not obvious but cannot be ruled out either.
Conclusions. The hard γ-ray object HESS J1702−420A remains unidentified, but the absence of a clear X-ray counterpart strongly challenges simple leptonic scenarios. The only remaining possible leptonic counterpart for HESS J1702−420A appears to be a newly discovered X-ray source with extended morphology and hard spectral index, which may be a PWN powered by a high-speed runaway pulsar.

ZusammenfassungIn den vergangenen Jahren hat der Einsatz mechanischer Unterstützungssysteme für Patienten mit Herz- und Kreislaufversagen kontinuierlich zugenommen, sodass in Deutschland mittlerweile
jährlich etwa 3000 ECLS-/ECMO-Systeme implantiert werden. Vor dem Hintergrund bislang fehlender umfassender Leitlinien bestand ein dringlicher Bedarf an der Formulierung evidenzbasierter
Empfehlungen zu den zentralen Aspekten der ECLS-/ECMO-Therapie. Im Juli 2015 wurde daher die Erstellung einer S3-Leitlinie durch die Deutsche Gesellschaft für Thorax-, Herz- und
Gefäßchirurgie (DGTHG) bei der zuständigen Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF) angemeldet. In einem strukturierten Konsensusprozess mit
Einbindung von Experten aus Deutschland, Österreich und der Schweiz, delegiert aus 11 AWMF-Fachgesellschaften, 5 weiteren Fachgesellschaften sowie der Patientenvertretung, entstand unter
Federführung der DGTHG die Leitlinie „Einsatz der extrakorporalen Zirkulation (ECLS/ECMO) bei Herz- und Kreislaufversagen“, die im Februar 2021 publiziert wurde. Die Leitlinie fokussiert
auf klinische Aspekte der Initiierung, Fortführung, Entwöhnung und Nachsorge und adressiert hierbei auch strukturelle und ökonomische Fragestellungen. Dieser Artikel präsentiert eine

Factor XII Explored with AlphaFold - Opportunities for Selective Drug Development

Published: September 2022

AbstractMedical device associated thrombosis is an important clinical problem. This type of thrombosis can result from Factor XII (FXII) binding to non-natural surface materials and subsequent activation of the contact pathway. This drives the development of new therapeutic strategies to block this pathway and information on the structural properties of FXII should catalyse this quest. Presently, there is no publicly available crystal structure of full-length FXII. However, the AlphaFold Protein Structure Database provides a model structure. We here explore this model in combination with previous structure-function studies to identify opportunities for selective pharmacological blockade of the contribution of FXII in medical device associated thrombosis. Previous studies demonstrated that FXII activation is dependent on molecular cleavage after R353. We subsequently proposed that protein conformation protects this cleavage site to ensure zymogen quiescence and prevent inappropriate FXII activation. The AlphaFold model shows that a small loop containing R353 indeed is buried in the globular molecule. This is the result of intra-molecular interactions between the (N-terminal) Fibronectin type II domain, (central) kringle and (C-terminal) protease domain, in a structure that resembles a three-point harness. Furthermore, this interaction pushes the intermediate domains, as well as the flexible proline-rich region (PRR), outward while encapsulating R353 in the molecule. The outward directed positively charged patches are likely to be involved in binding to anionic surfaces. The binding of FXII to surfaces (and several monoclonal antibodies) acccelerates its activation by inducing conformational changes. For prevention of medical device associated thrombosis, it is therefore important to target the surface binding sites of FXII without causing structural changes.

Published: September 2022

Abstract
Background The patient portal allows patients to engage with their health care team beyond the clinical encounter. While portals can improve patient outcomes, there may be disparities in which patients access the portal by sociodemographic factors. Understanding the characteristics of patients who use the portal could help design future interventions to expand portal adoption.
Objectives This study aimed to (1) examine the socioeconomic factors, comorbid conditions, and health care utilization among patients of a large academic primary care network who are users and non-users of the patient portal; and (2) describe the portal functions most frequently utilized.
Methods We included all adult patients at Atrium Health Wake Forest Baptist who had at least two primary care visits between 2018 and 2019. Patients' demographics, comorbidities, health care utilization, and portal function usage were extracted from the electronic health record and merged with census data (income, education, and unemployment) from the American Community Survey. A myWakeHealth portal user was defined as a patient who used a bidirectional portal function at least once during the study period. We used multivariable logistic regression to determine which patient characteristics were independently associated with being a portal user.
Results Of the 178,720 patients who met inclusion criteria, 32% (N = 57,122) were users of myWakeHealth. Compared to non-users, users were more likely to be 18 to 64 years of age, female, non-Hispanic White, married, commercially insured, have higher disease burden, and have lower health care utilization. Patients residing in areas with the highest educational attainment had 51% higher odds of being a portal user than the lowest (p <0.001). Among portal users, the most commonly used function was messaging clinic providers.
Conclusion We found that patient demographics and area socioeconomic factors were associated with patient portal adoption. These findings suggest that efforts to improve portal adoption should be targeted at vulnerable patients.

Published: September 2022

Abstract
Objectives To estimate gingival crevicular immunoglobulin A(IgA) using enzyme-linked immunosorbent assay (ELISA) among type II diabetic patients with periodontitis.
Materials and Methods A non-randomized study was done of 40 periodontitis subjects with a mean age of 50 years and were recruited into two groups, Group A (Type II controlled diabetics with HbA1c < 7%) and Group B (non-diabetics with HbA1c between 4 and 6%). Both the groups underwent nonsurgical periodontal therapy (NSPT). The clinical parameters were recorded at baseline, 1, and 3 months. GCF sample was collected for the estimation of crevicular IgA at baseline and at 3 months.
Statistical Analysis Results were analyzed using parametric tests paired t-test and Student's t-test for every assessment point. The level of significance was set at p < 0.05.
Results Difference in IgA levels and clinical parameters was seen between diabetic and non-diabetic groups, which was statistically significant.
Conclusion Changes in crevicular IgA levels in patients with diabetic periodontitis can be used as a novel biomarker in assessing the inflammatory status.
