Abstract
Thermoelectric generators enable the conversion of waste heat to electricity, which is an effective way to alleviate the global energy crisis. However, the inefficiency of thermoelectric materials is the main obstacle for realizing their widespread applications and thus developing materials with high thermoelectric performance is urgent. Here we show that multiple valence bands and strong phonon scattering can be realized simultaneously in p-type PbSe through the incorporation of AgInSe2. The multiple valleys enable large weighted mobility, indicating enhanced electrical properties. Local structure and microstructure analysis reveal that about 80 percent of Ag and In atoms form AgInSe2 as nano-scale precipitates, which result in strong phonon scattering and thus ultralow lattice thermal conductivity. Consequently, we achieve an exceptional ZT of ~ 2.1 at 873 K in p-type PbSe. Our results demonstrate that a combination of band manipulation and microstructure engineering can be realized by tuning the composition. We expect our findings to be a general strategy for achieving high thermoelectric performance in bulk material, pushing the thermoelectric materials for realistic applications.
Coronamoeba villafranca gen. nov. sp. nov. (Amoebozoa, Dermamoebida) – the first marine amoeba related to Dermamoeba and Paradermamoeba, challenges the correlation of morphology and phylogeny in Amoebozoa

Abstract
Coronamoeba villafranca gen. nov. sp. nov. is a small amoeba isolated from the surface planktonic biotope in the Bay of Villefranche (Mediterranean Sea). It has a confusing set of morphological and molecular characters. Its locomotive form is subcylindrical and monopodial with monoaxial cytoplasmic flow and occasional hyaline bulging at anterior edge (a monotactic morphotype). Based on this set of characters this amoeba is most similar to the members of the genus Nolandella (Tubulinea, Euamoebida). However, molecular phylogenetic analysis based on the single marker small subunit ribosomal RNA (SSU rRNA) gene and on two concatenated markers (SSU rRNA gene and actin) robustly places this species in the Discosea, specifically, in a clade with Dermamoeba and Paradermamoeba (Dermamoebida) as the closest relatives. A unique glycocalyx of the studied amoeba consisting of complex separate units with pentagonal symmetry may be considered a unifying character of this species with other dermamoebids. The results obtained favor a hypothesis that the monotactic morphotype that primarily occurs in Tubulinea, but was recently confirmed in other clades of Amoebozoa (e.g. Dactylopodida and Variosea) may be the plesiomorphic mode of amoeboid cell organization in this supergroup. It may reflect basic characters of the cytoskeletal structure and functions in Amoebozoa.

Abstract
In this paper, we investigate superextreme spiking (SES) oscillations and multistability in a memristor based Hindmarsh-Rose (HR) neuron model. The bounded chaotic spiking (BCS) oscillations is transit as superexterme spiking (SES) oscillations for a critical membrane input current, which is caused by an interior crisis. The occurrence of very large amplitude spiking oscillations has long tail distribution is characterized by the probability distribution function (PDF). Also, we distinguish the bounded chaotic and superextreme spiking oscillations by using the inter spike interval (ISI) return map. Additionally, we explore the multistability of spikes, for two different initial conditions, is explored by the phase portraits, bifurcation diagrams and maximum Lyapunov exponents. We provide an analog electronic circuit realization of the memristor based HR neuron model, the experimentally observed results shows that our numerical results are in good accord.

Abstract
Clay soils consist of fine particles and are generally characterized by low strength. The interactions between clays and water result in high-plasticity clay mixtures that can easily deform or crack. It should be noted that the addition of sand to expansive soils can help to improve their particle size and reduce their plasticity, and consequently augment their strength. The present study aims mainly to develop a model for the prediction of the plasticity index (PI) of soil treated with sand, at various contents using the artificial neural network (ANN) method. It was revealed that the ANN technique ensures good prediction accuracy for a large number of parameters related to geotechnical problems. For the purpose of predicting the plasticity index values of sand-treated soils, the results of experimental tests that were conducted on 38 soil samples were collected and thoroughly analyzed. It was decided to consider three inputs, namely the plastic limit, liquid limit, and sand percentage, while there was only one output, i.e. the plasticity index. The results of the analyses conducted in this study indicated that the artificial neural network (ANN) model might be quite efficient in predicting the plasticity index of soils treated with sand. Afterwards, an experimental investigation was carried out on the clayey soil that was brought from the Wilaya (Province) of Medea in Algeria. This soil was treated with dune sand at different percentages, and the results obtained were compared with those predicted by the artificial neural network (ANN) technique.

Abstract
In order to better meet the communication needs of the hearing impaired and the general public, it is of great significance to recognize sign language more quickly and accurately in the embedded platforms and mobile terminals. A sign language recognition method based on the ShuffleNetv2-YOLOv3 lightweight model was proposed. By Using ShuffleNetv2 as the backbone network of the YOLOv3 model, the ShuffleNetv2-YOLOv3 method improved the recognition speed by the lightweight network with the CIoU loss function and more less detection layers; kept the recognition accuracy of similar gestures that were difficult to accurately recognize. Statistical analysis of the self-made sign language images was carried out to evaluate the recognition effectiveness of the model by F1 score and mAP value, and to compare it with YOLOv3-tiny, SSD, Faster-RCNN, MobileNetv2-YOLOv3, and YOLOv4-tiny models, respectively. The experimental results show that the proposed ShuffleNetv2-YOLOv3 model achieved a good balance between the accuracy and speed of gesture detection under the premise of model lightweight. The F1 score and mAP value of the ShuffleNetv2-YOLOv3 model were 99.1% and 98.4%, respectively, and the target detection speed on the GPU can reach 54 frames per second, which is better than other models. The ShuffleNetv2-YOLOv3 sign language recognition method is conducive to quick, real-time, and similar static sign language gesture recognition, which lays a good foundation for real-time dynamic gesture recognition.

Abstract

The following article analyzes the determinants of the innovation index in Europe. The data refer to the European Innovation Scoreboard-EIS of the European Commission for the period between 2010 and 2019 for 36 countries. The data are analyzed using the following econometric techniques: Panel Data with Random Effects, Panel Data with Fixed Effects, Dynamic Panel Data, Pooled OLS, WLS. The results show that the Innovation Index is negatively connected to some variables, among which the most significant are "GDP per capita", "R&D expenditure public sector", "Venture capital", "Tertiary education", and positively connected to some variables among which the most relevant are: "Government procurement of advanced technology products", "Average annual population growth", "Finance and support", "Human resources", "Marketing or organisational innovators", "Linkages". A clustering was then carried out using the unsupervised k-Means algorithm optimized with the Silhouette coefficient which shows the presence of 2 clusters per value of the Innovation Index. Eight machine learning algorithms has been used for prediction with real data. The Tree Ensemble Regression algorithm has been chosen as best performer. A further prediction has been made with the augmented data. The result shows that the best performing algorithm is Linear Regression with an innovation index value predicted to grow by approximately 3.38%.

Authors: Hai Dao Thanh 
Published: April 2022

Abstract
A new architectural paradigm for future optical transport network, namely, optical-processing-enabled networking, is presented. As a major departure from traditional optical-bypass framework, the new paradigm is grounded on the idea of permitting superposition of transitional lightpaths crossing the same intermediate node to produce a more spectrally efficient lightpath bringing about spectral savings and potentially greater energy efficiency. A case study focusing on optical aggregation is provided to highlight how advantageous the proposed architecture is in comparison with the conventional one.
Analyzing the Effects of the Dwelling Characteristics on the Space Heating Costs with Bayesian Networks
Authors: Sevinç Volkan 
Published: April 2022

Abstract
Energy is one of the main concerns of humanity because energy resources are limited and costly. Hence, effective use of energy is important. In order to reduce the costs and to use the energy for space heating effectively, new building materials, techniques and insulations facilities are being developed. Therefore, it is important to know which factors affect the space heating costs. This study aims to introduce the use of Bayesian networks to analyze the effects of dwelling characteristics on the space heating costs. The Bayesian Network model shows that the space heating costs of the dwellings are mostly affected by the heating systems used. The second important factor appears to be the existence of external wall insulation. The third most important factor, however, is the building age. Additionally, dwellings on the ground floors and on the first floors appear to pay the highest space heating costs. On the other hand, dwelling type and facing direction seem not to have a considerable effect on the space heating costs.

A Single Dose of Local Injection of Adipose Stem Cells Promotes Ectopic
Cartilage Regeneration In Vivo by Modulating Inflammatory Response
and Enhancing Cartilage Extracellular Matrix Synthesis in a Porcine
Model
Authors: Huang Tianyu , Sun Hengyun , Chen Jianguo , Liu Xia , Pan Bo , He Leren , Jiang Haiyue 
Published: April 2022

Background:
Uncontrollable inflammatory response following ectopic engineered cartilage
implantation is devastating to the aesthetic and functional outcomes of the recipients. Adipose stem cells
(ASCs) have a good immunomodulatory capacity via a paracrine mechanism. However, works of literature
are scarce regarding ASC modulation in ectopic engineered cartilage regeneration in vivo. This study
aims to explore how ASCs modulate the inflammatory response after engineered cartilage implantation
and affect the implants in a nonchondrogenic milieu in large immunocompetent animals.

Methods:
Porcine engineered elastic cartilages were cultured in vitro for 3 weeks with chondrocyte cell
sheeting technology and then assigned into two groups: ASCs and Control (saline injection). All samples
(n= 6 per group) were autologously implanted into different subcutaneous pockets, and a single dose of
ASCs was injected at three points around the implant. All samples were harvested after 2 weeks in vivo
for analysis.

Results:
In the examination of inflammation, we observed reduced inflammatory cell infiltration and
improved M2 macrophage polarization in the implanted engineered cartilage with ASC injection compared
to the control. There were also enhanced anti-inflammatory cytokines and reduced proinflammatory
cytokines inside and adjacent to the implants, while in serum, there were no significant differences. In the
examination of the cartilage quality, there were significant increases in cartilage extracellular matrix and
chondrogenic factors, and the elastic cartilage phenotype was maintained compared to control.

Conclusion:
This study finds that a single dose of ASCs can promote ectopic cartilage regeneration by
modulating inflammation and enhancing cartilage matrix synthesis in a porcine model.
