AbstractThe wood-based furniture manufacturing industries prioritize quality of production to meet higher market demands. Identifying various types of edge-glued wooden panel defects are a challenge for a human worker or a camera. Several studies have shown that the detection of edge-glued defects with low, high, normal, overlong, short is identified but detection of residue and bluntness is highly challenging. Thus, the present model identifies defects of low, high, normal, overlong, short by computer vision and/or deep learning, whereas defects of residue and bluntness by deep learning based decide by pass for having better performance. The goal of this paper is to provide an improved defect detection solution for wood-based furniture manufacturing industries by process automation. Therefore, a system was designed that takes defect input images from a camera as raw image and laser-aligned image for defect detection of the edge-glued wooden panel. The process automation then performs computer vision-based image features extraction with deep learning for defect detection. The aim of this paper is to solve edge-glued defect detection problems by using design and implementation of edge-glued wooden defect detection, that can be stated as edge-glued wooden panel defect detection using deep learning (WDD-DL) for process automation by artificial intelligence and Automated Optical Inspection (AOI) consolidation. Possibly there exist several types of defects on the edges while edge-banding on the wooden panel in furniture manufacturing. Therefore, the scope is to achieve higher accuracy by raw image and laser-aligned image feature extraction using deep learning algorithms for final result defect classification in WDD-DL by AOI. The WDD-DL system uses Gabor, Harris corner, morphology, structured light detection and curvature calculation for pre-processing and InceptionResnetV2 Convolutional Neural Network algorithm to attain the best results. The applications of this work can be found in quality control of the furniture manufacturing industry for an edge, corner, joint defect detection of the wooden panels. The WDD-DL achieves best results as the precision, recall and F1 score are 0.97, 0.90 and 0.92, respectively. The experiments demonstrate higher accuracy achievement as compared to other methods with overkill and escape rate analysis. Ultimately, the discussion section provides an interesting experience sharing about the necessary factors for implementing the WDD-DL in real-time industrial operations.
Iron Age plant subsistence in the Inner Congo Basin (DR Congo)
Authors: Neumann Katharina , Eichhorn Barbara , Wotzka Hans-Peter 
Published: January 2022

AbstractAround 400bc, pottery- and iron-producing populations immigrated into the Inner Congo Basin (ICB) and subsequently spread upstream some major tributaries of the Congo River. Until recently, their subsistence was almost completely unknown. We present an archaeobotanical study of three sites in the ICB covering parts of the Early Iron Age (ca. 400bc-ad650) and of the Late Iron Age (LIA) as well as subrecent times (ca.ad1300–2000). We studied 82 flotated samples of botanical macroremains, and 68 soil phytolith samples, recovered from the terra firmesites Iyonda and Mbandaka, and the floodplain fishing camp site of Bolondo. The EIA assemblage from Iyonda yielded domesticatedCenchrus americanus(pearl millet),Vigna unguiculata(cowpea),Canarium schweinfurthii,Elaeis guineensis(oil palm), several wild plants, and parenchyma fragments tentatively attributed toDioscoreasp. (yams). The exploitation of these plants originated in the savannas and forest-savanna ecotones of West Africa. The presence ofC. americanusin LIA contexts at Bolondo and Mbandaka, dated to ca.ad1350–1550, indicates that its cultivation is not dependent on a seasonal climate with a distinct dry season, contrary to previous views. The role ofC. americanusas a staple is difficult to assess; it might have been used for special purposes, e.g. beer brewing. In spite of extensive screening, we did not detect any banana phytoliths in the EIA samples.Musaphytoliths were only present in LIA contexts after ca.ad1400, leaving room for the possibility that the introduction and spread ofMusa spp. AAB ‘Plantain’ in the ICB was a late phenomenon.

Abstract
Purpose
Assessing hepatic vein reconstruction using a left renal vein graft and in situ hypothermic liver perfusion in an extended liver resection.

Methods
Patients included in this study were those with liver tumors undergoing curative surgery with resection and reconstruction of hepatic veins. Hepatic vein was reconstructed using a left renal vein graft. We describe the technical aspects of liver resection and vascular reconstruction, the key aspects of hemodynamic management, and the use of in situ hypothermic liver preservations during liver transection (prior to and during vascular clamping).

Results
The right hepatic vein was reconstructed with a median left renal venal graft length of 4.5 cm (IQR, 3.1–5.2). Creatinine levels remained within normal limits in the immediate postoperative phase and during follow-up. Median blood loss was 500 ml (IQR, 300–1500) and in situ perfusion with cold ischemia was 67 min (IQR, 60.5–77.5). The grafts remained patent during the follow-up with no signs of thrombosis. No major postoperative complications were observed.

Conclusion
Left renal vein graft for the reconstruction of a hepatic vein and in situ hypothermic liver perfusion are feasible during extended liver resection.
Koordination von Raumplanung und Wasserbau als wesentlicher Bestandteil des Hochwasserrisikomanagements
Authors: Seher Walter , Neuhold Clemens 
Published: January 2022

ZusammenfassungAls Folge der Umsetzung der EU-Hochwasserrichtlinie haben flächen- und raumbezogene Aspekte im Hochwasserrisikomanagement an Bedeutung gewonnen. Dadurch und durch Herausforderungen wie die hohe Flächeninanspruchnahme für Bauland und Verkehrsflächen erhöht sich der Koordinationsbedarf zwischen Raumplanung und Wasserbau. Die ÖROK-Empfehlungen Nr. 57 „Hochwasserrisikomanagement“ tragen diesem Umstand Rechnung und geben als Ergebnis einer inhaltlichen Abstimmung zwischen Raumplanungs- und Wasserbauakteuren Leitlinien für den Umgang mit Hochwassergefahren und Hochwasserrisiken in der Raumplanung vor. Der vorliegende Beitrag nimmt diese ÖROK-Empfehlungen als Grundlage und legt den Schwerpunkt auf jene Empfehlungen, die direkt auf die Koordination der überörtlichen bzw. örtlichen Raumplanung mit dem Wasserbau abzielen. Im Zusammenhang mit der empfohlenen Berücksichtigung von Hochwasserabfluss- und Hochwasserrückhalteflächen in den Instrumenten der überörtlichen Raumplanung ist besonders die inhaltliche Abstimmung zwischen Raumplanung und Wasserbau gefordert, um die Freihaltung dieser Flächen als Anliegen der Regionalplanung in den Raumordnungsgesetzen zu verankern. Die Berücksichtigung von Gebieten mit Überflutung hoher und mittlerer Wahrscheinlichkeit in der örtlichen Raumplanung ist teils in den Raumordnungsgesetzen mit Bezug zu bestimmten Grenzwerten der Gefährdung festgelegt, teils gewährleistet die administrative Koordination zwischen den Gemeinden und den wasserbaulichen Fachdiensten im Raumordnungsverfahren eine standardisierte Vorgehensweise bei der Gefahrenbeurteilung. Von großer Bedeutung ist die administrative Koordination von Raumplanung und Wasserbau auch im Umgang mit gewidmetem Bauland in Zonen mit mittlerer Überflutungswahrscheinlichkeit und bei pluvialen Hochwassergefahren sowie bei Nutzungsentscheidungen in Hochwasserabflussbereichen mit geringer Eintrittswahrscheinlichkeit und Restrisikogebieten, wo im Raumordnungsrecht nur vereinzelt normative Vorgaben bestehen.
Enhanced loaded tooth contact analysis of hypoid gears within a multi-body-system simulation
Authors: Wagner Wolf , Schumann Stefan , Schlecht Berthold 
Published: January 2022

AbstractTo calculate the load capacity of gear stages within complex drivetrains under varying external loads, multi-body-systems (MBS) are used to simulate the vibrational behaviour of integral systems. In order to model a flexible hypoid gear stage, methods like the modal reduction of FEM-models were already introduced. However, the modelling of such systems is complex, challenging and sensitive to its discretisation. The co-simulation within a multi-body-system simulation offers the possibility to outsource the calculation of the tooth contact and therefore the reaction forces under consideration of friction. This leads to a simplification and an improvement of the modelling of gear stages in multi-body-systems.The further developed co-simulation module offers a compromise between computational speeds and exact solutions. To improve the quality of the results and reduce the calculation time the load distribution calculation is investigated specifically. The article describes a method to reduce fluctuations of computed reaction forces and moments during gear movement. The aim is to keep the level of fluctuations of a high contact zone discretisation with a significant smaller contact point count.
Effect of clouds on emission spectra for super Venus
Authors: Wolkenberg Paulina , Turrini Diego 
Published: January 2022

AbstractWe report a model study on the effects of clouds on emission spectra of super-Venus planets. Our goal is to assess possible ways to identify characteristic spectral features due to clouds. We show that it is possible to distinguish an impact of H2SO4 clouds on the CO2 absorption band at 4.8 μm for temperature profiles with and without a thermal inversion. The thermal inversion can help to distinguish the signal from high altitude clouds (85 km, ∼1 mbar). Featureless emission spectra are found for high altitude clouds (85 km, ∼1 mbar) with temperature profile without thermal inversion. More spectral features appear in the emission spectra with decreasing cloud top altitudes. The compactness of clouds has an inverse effect on emission spectra than cloud top altitudes. Small cloud scale heights reduce the signal and the CO2 absorption bands become flat.
The potential effects of climate change on the populations of Aedes punctor (Diptera: Culicidae) in Hungary
Authors: Trájer Attila J. 
Published: January 2022

AbstractIn Hungary, the boreal-alpine mosquitoAedes punctorhas a disjunct distribution limited to the Hungarian mid-mountains. The aim of this study was to investigate the potential effect of global warming on the future (2041–2060 and 2061–2080) climatic suitability for the mosquito in Hungary. The results indicate the heterogeneous, but in general, the negative effect of climate change on the distribution area ofAedes punctorin this region. The models predict the total loss of mosquito habitat in the Transdanubian mountain ranges (Bakony-Balaton and Mecsek Mts.) for 2061–2080. In the North Hungarian Mountains (in the Mátra Mts.), climatic alterations may result in the habitat contraction, but not total disappearance of the climatically suitable areas forAedes punctorat higher elevations of mountain ranges. It can be concluded that climate change can cause the altitudinal shift of the suitable habitats and the range-contraction of Hungarian middle mountains-inhabiting populations of the mosquito in Hungary in the second half of the twenty-first century assuming that the future climatic needs of the species would remain the same as at present.
Hardware Implementation of a Fixed-Point Decoder for Low-Density Lattice Codes
Authors: Srivastava Rachna , Gaudet Vincent C. , Mitran Patrick 
Published: January 2022

AbstractThis paper describes a field-programmable gate array (FPGA) implementation of a fixed-point low-density lattice code (LDLC) decoder where the Gaussian mixture messages that are exchanged during the iterative decoding process are approximated to a single Gaussian. A detailed quantization study is first performed to find the minimum number of bits required for the fixed-point decoder to attain a frame error rate (FER) performance similar to floating-point. Then efficient numerical methods are devised to approximate the required non-linear functions. Finally, the paper presents a comparison of the performance of the different decoder architectures as well as a detailed analysis of the resource requirements and throughput trade-offs of the primary design blocks for the different architectures. A novel pipelined LDLC decoder architecture is proposed where resource re-utilization along with pipelining allows for a parallelism equivalent to 50 variable nodes on the target FPGA device. The pipelined architecture attains a throughput of 10.5 Msymbols/sec at a distance of 5 dB from capacity which is a 1.8$$\times$$
×
improvement in throughput compared to an implementation with 20 parallel variable nodes without pipelining. This implementation also achieves 24$$\times$$
×
improvement in throughput over a baseline serial decoder.
The Effect of Hyperoxemia on Neurological Outcomes of Adult Patients: A Systematic Review and Meta-Analysis

Published: January 2022

AbstractHyperoxemia commonly occurs in clinical practice and is often left untreated. Many studies have shown increased mortality in patients with hyperoxemia, but data on neurological outcome in these patients are conflicting, despite worsened neurological outcome found in preclinical studies. To investigate the association between hyperoxemia and neurological outcome in adult patients, we performed a systematic review and meta-analysis of observational studies. We searched MEDLINE, Embase, Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature, and ClinicalTrials.gov from inception to May 2020 for observational studies correlating arterial oxygen partial pressure (PaO2) with neurological status in adults hospitalized with acute conditions. Studies of chronic pulmonary disease or hyperbaric oxygenation were excluded. Relative risks (RRs) were pooled at the study level by using a random-effects model to compare the risk of poor neurological outcome in patients with hyperoxemia and patients without hyperoxemia. Sensitivity and subgroup analyses and assessments of publication bias and risk of bias were performed. Maximum and mean PaO2 in patients with favorable and unfavorable outcomes were compared using standardized mean difference (SMD). Of 6255 records screened, 32 studies were analyzed. Overall, hyperoxemia was significantly associated with an increased risk of poor neurological outcome (RR 1.13, 95% confidence interval [CI] 1.05–1.23, statistical heterogeneity I2 58.8%, 22 studies). The results were robust across sensitivity analyses. Patients with unfavorable outcome also showed a significantly higher maximum PaO2 (SMD 0.17, 95% CI 0.04–0.30, I2 78.4%, 15 studies) and mean PaO2 (SMD 0.25, 95% CI 0.04–0.45, I2 91.0%, 13 studies). These associations were pronounced in patients with subarachnoid hemorrhage (RR 1.34, 95% CI 1.14–1.56) and ischemic stroke (RR 1.41, 95% CI 1.14–1.74), but not in patients with cardiac arrest, traumatic brain injury, or following cardiopulmonary bypass. Hyperoxemia is associated with poor neurological outcome, especially in patients with subarachnoid hemorrhage and ischemic stroke. Although our study cannot establish causality, PaO2 should be monitored closely because hyperoxemia may be associated with worsened patient outcome and consequently affect the patient’s quality of life.
Talent detection—importance of the will and the ability when starting a sport activity

Published: January 2022

AbstractThe early identification of sports talents includes finding the right sport and is of great importance for both scientists and practitioners. In this article, special attention will be paid to the entry into sports in general as a basis of a talent development process. Sport-specific evidence from a variety of talent development models will be listed and research gaps will be identified. For this purpose, this article refers to a model that can be classified as both process and structure oriented and tries to find domain-specific application. A framework is presented as a research approach in which the different scientific disciplines can bring together their subject areas. This enables so-called ability–personality profiles consisting individual constellations of motivation variables, interests, skills, and experience to be studied together and incorporated into the talent development process. The arrangement of movement offers should be oriented to the individual profiles. At the same time, movement experiences can offer the basis for the formation of interests, motivation, and sport-motor skills, i.e., of the will and the ability. Taking the will into account as well as the ability could lead people to detect their own talent (based on contents of the presented framework) and the sport that is suitable for them, and thus be ready for the entry to the path of talent development.
Traffic Signal Control Parameter Calculation Using Probe Data

Published: January 2022

AbstractIn signal control, which is one of the main functions of traffic control systems, appropriate signal control parameters are calculated based on the measurement data from vehicle detectors installed on the road. However, the installation and maintenance of vehicle detectors is costly, so realization of a signal control system that can reduce the number of vehicle detectors used while maintaining control level is required. In this paper, we propose a method to calculate signal control parameters without using measurement data from vehicle detectors using traffic information obtained from probe data.
Analysis of nonlinear effects in fluid flows through porous media
Authors: Zolotukhin A. B. , Gayubov A. T. 
Published: January 2022

AbstractThis article examines the nonlinear effects of fluid flow in a porous medium, governed by a new semi-analytical equation, from three aspects: equation derivation, experimental verification, and macroscale simulation modelling. The rigorous derivation of the new equation is presented with a semi-analytical approach in which the gas slippage effect and inertial forces are described. The latter effect is controlled by Fochheimer number, which is defined as a product of tortuosity and Reynolds number. The new equation successfully predicts the deviations from Darcy’s law in low-permeability media when the gas slippage effect occurs. The Klinkenberg gas slippage factor is obtained as a function of porous media’s structural parameter (porosity and intrinsic permeability) and gas property (mean free path of gas molecules). The equation validations are performed by core flow experiments for a wide range of reservoir properties, which yield good matching relationship between modelled and observed values. In addition, the proposed semi-analytical equation is used to simulate gas flow in the radial model.

Investor Capitalism, Sustainable Investment and the Role of Tax Relief
Authors: Katelouzou Dionysia , Micheler Eva 
Published: January 2022

AbstractThis contribution examines the connection between investor capitalism and sustainable investment. It will be observed in this article that investor capitalism has gone through a structural change. Individual investors have been replaced by funds. Financial service providers have emerged that assist investors in managing and holding investments. This development coincided and was arguably facilitated by the growth in workplace and personal pensions. Pensions are subsidised by the government through tax relief. This financial contribution of the government is justified on social policy grounds. But it has the effect that pension savers, who receive substantial return by saving tax, are deprived of a reason to take an interest in how their money is invested. This not only deprives the service providers assisting pension savers from oversight from their ultimate customers. It also can help to explain why pension savers do not actively select investment products but rely on the default settings suggested by their employers. If the government is serious about encouraging investor capitalism to bring about sustainable business it should start with its own financial contribution, which has coincided with the emergence of the current model of investor capitalism, and connect pension tax relief to sustainable investment practices.
