Published: March 2023

Bacterial fruit blotch (BFB), caused by Acidovorax citrulli, severely damages watermelon, melon, and other cucurbit crops worldwide. Nitrogen, one of the most important limiting elements in the environment, is necessary for the growth and reproduction of bacteria. As a nitrogen-regulating gene, ntrC plays an important role in maintaining bacterial nitrogen utilization and biological nitrogen fixation. However, the role of ntrC has not been determined for A. citrulli. In this study, we constructed a ntrC deletion mutant and a corresponding complementary strain in the background of the A. citrulli wild-type strain, Aac5. Through phenotype assays and qRT-PCR analysis, we investigated the role of ntrC in A. citrulli in nitrogen utilization, stress tolerance, and virulence against watermelon seedlings. Our results showed that the A. citrulli Aac5 ntrC deletion mutant lost the ability to utilize nitrate. The ntrC mutant strain also exhibited significantly decreased virulence, in vitro growth, in vivo colonization ability, swimming motility, and twitching motility. In contrast, it displayed significantly enhanced biofilm formation and tolerance to stress induced by oxygen, high salt, and copper ions. The qRT-PCR results showed that the nitrate utilization gene nasS; the Type III secretion system-related genes hrpE, hrpX, and hrcJ; and the pili-related gene pilA were significantly downregulated in the ntrC deletion mutant. The nitrate utilization gene nasT, and the flagellum-related genes flhD, flhC, fliA, and fliC were significantly upregulated in the ntrC deletion mutant. The expression levels of ntrC gene in the MMX-q and XVM2 media were significantly higher than in the KB medium. These results suggest that the ntrC gene plays a pivotal role in the nitrogen utilization, stress tolerance, and virulence of A. citrulli.

Necrotic enteritis (NE) is an economically important disease of chickens. We have recently shown that inflammatory responses in chickens inoculated orally with virulent Clostridium perfringens were spatially regulated. Here, we used previously virulence-characterized netB+ C. perfringens strains, avirulent CP5 and virulent CP18 and CP26, to assess the severity of NE and immune responses in broiler chickens when inoculated intracloacally. The results showed that CP18- and CP26-infected birds had a reduced weight gain and developed milder/less severe NE lesions, as determined by the gross lesions scores, suggesting a subclinical-grade infection. Gene expression analysis in infected birds revealed three statistically significant observations compared to uninfected-control: (1) Increased expression of anti-inflammatory/immunoregulatory interleukin (IL)-10/transforming growth factor (TGF)β in cecal tonsil (CT) and bursa of Fabricius in the CP18/CP26-infected groups. (2) Increased CT transcription of pro-inflammatory IL-1β, IL-6 and interferon (IFN)γ and decreased Harderian gland (HG) expression of IFNγ in the CP18/CP26-infected birds. (3) Increased HG or bursal expression of IL-4 and IL-13 in CP5-infected birds. Collectively, intracloacal C. perfringens inoculation seems to induce a highly regulated inflammatory response in the CT and other mucosal lymphoid organs and an intracloacal infection model may be useful in evaluating immune responses in chickens with subclinical NE.

Equine and canine anaplasmosis and borreliosis are major tick-borne zoonotic diseases caused by Anaplasma phagocytophilum and various species of Borrelia (the most important being Borrelia burgdorferi s.l.), respectively. This study evaluated the seroexposure to Anaplasma and Borrelia in dogs and horses used in Animal-Assisted Interventions or living in contact with children, elderly people or immunocompromised persons. A total of 150 horses and 150 dogs living in Italy were equally divided into clinically healthy animals and animals with at least one clinical sign compatible with borreliosis and/or anaplasmosis (present at clinical examination or reported in the medical history). Serum samples were tested with ELISA and immunoblot for the presence of antibodies against A. phagocytophilum and B. burgdorferi s.l., and the association between seropositivity and possible risk factors was analyzed using multivariate and univariate tests. Overall, 13 dogs (8.7%) and 19 horses (12.7%) were positive for at least one of the two pathogens. In addition, 1 dog (0.7%) and 12 horses (8%) were positive for antibodies against A. phagocytophilum, while 12 dogs (8.0%) and 10 horses (6.7%) had antibodies against B. burgdorferi s.l. Tick infestation in the medical history of the dogs was significantly associated with seropositivity to at least one pathogen (p = 0.027; OR 7.398). These results indicate that, in Italy, ticks infected with A. phagocytophilum and/or B. burgdorferi circulate in places where horses and dogs are in contact with people at risk of developing severe diseases. Awareness should be increased, and adequate control plans need to be developed to protect human and animal health, especially where vulnerable, at-risk individuals are concerned.

Régionalisations et régionalismes dans une Europe élargie : les enjeux d'une comparaison Est-Ouest

Regionalization and regionalisms in a bigger Europe: The issues in an East-West comparison
In recent decades, the framework for analyzing regional issues has nearly always been based on empirical cases from western Europe. Three principal patterns can be distinguished: the ethno-territorial constructivist current of thought, the multi-level governance model and neoregionalism. But can they be generalized to a EU with 27 members? Does the bigger EU imply changing our grids for interpreting regional phenomena in Europe? After testing these theoretical west European patterns by applying them to eastern Europe, a series of variables is presented for restudying regionalism and regionalization in an enlarged Europe.
Une régionalisation sous étroite surveillance : l'exemple tchèque d'une régionalisation sans régionalisme

Tightly supervised regionalization:
The Czech example of regionalization without regionalism
One of the principal reforms made during the post-Communist era in central and eastern European countries has been the establishment of regional structures. It occurred while a wave of regionalization was sweeping over western Europe. Unlike in the West however, where grassroots political, economic and social forces were at work (along with external factors such as globalization and Europeanization), regionalization in the Czech Republic took place in the absence of any mobilization of regional or regionalist forces. Regional construction was launched at the top of the state, on the initiative of the ruling elites who wanted to both rationalize the operation of the territorial administration and, above all, maintain their control over state power and resources. What kind of regional forces might emerge out of the establishment of regions and, as a consequence, the reception of EU structural funds?
Deux modèles de pouvoir : une étude empirique dans le milieu carcéral russe

Two models of power: An empirical study in theRussian carcéral environment
Deeply enrooted in Russian history, the samovlastie runs through the history of the Soviet and post-Soviet periods. This particular model of power has five characteristics: (i) it is a "power over" rather than the "power to"; (ii) relations between superior and inferior are extremely asymmetrical; (iii) the inferior have no say; (iv) the only justification of this power is the exercise of power itself; and (v) violent techniques (force, coercion, manipulation) prevail. The reproduction of samovlastie through the Soviet and post-Soviet history can explain the continuity in Russia's political and economic evolution. An alternative model of power relations, illustrated by informal leaders in prison, differs from the samovlastie in all five respects. In the repertory of techniques, a new one - "domination by virtue of a constellation of interests" - has arisen out of a nearly rational choice in the conditions of imperfect competition and other biases in market structure.

Published: March 2023

Las imágenes médicas de la anatomía maxilofacial pueden ser consideradas como una de las más difundidas e importantes en la imagen diagnóstica de la actualidad.
Una imagen del aparato masticatorio es relevante desde el punto de vista de la medicina, para tratamientos tan comunes como una ortodoncia hasta tratamientos complejos como un implante óseo.
Actualmente los tipos de imágenes para diagnóstico más utilizadas en este campo son la Radiografía Panorámica Tradicional en el campo de la Ortopantomografía (OPG) y la Tomografía Computada (CT). Los odontólogos y médicos actuales solicitan este tipo de exámenes médicos para hacer diagnóstico de enfermedades, lesiones o estudios previos a los tratamientos.
Dado que estas imágenes médicas son las más comunes y difundidas, es importante conocer que características, ventajas y desventajas ofrecen cada una de ellas en el contexto de la odontología y que aplicaciones clínicas específicas existen para OPG y CT.
En esta investigación se expondrá también temas poco estudiados en las imágenes médicas del sistema maxilofacial y odontológicas, como lo es el cálculo de dosis y protección radiológica tanto en OPG como en CT. Se expondrá brevemente también, aspectos básicos de la calidad de imagen en ambos tipos de obtención de imagen. Finalmente se expone una comparación entre ambos métodos.

Abstract
With excellent stability, flexibility, and piezoelectricity, poly(vinylidene fluoride) (PVDF) and its copolymer [P(VDF-TrFE)] have received much attention. However, the applications for its ferroelectricity still suffer the drawbacks of relative low remanent polarization (P
r) and high coercive electric field (E
c). In this work, P(VDF-TrFE) composite films were fabricated with the additive of organic perovskite ferroelectric MDABCO-NH4I3. Compared with pure P(VDF-TrFE), the P
r increases from 7.17 to 12.7 μC cm−2, while E
c decreases from 516 to 324 kV cm−1 as well as increased permittivity from 15.6 to 37.0. These may provide an alternative way for ferroelectric memory, sensors, and energy storage devices.
Design of Near-Field Beamforming for Large Intelligent Surfaces
Authors: Hu Sha , Wang Hao , ilter mehmet 
Published: March 2023

<p>In this paper, we propose a novel three-dimensional (3D) near-field beamforming (BF) design for Large Intelligent Surface (LIS). We firstly investigate the definitions of near-field and far-field of LIS, and derive the Fresnel near-field region where amplitudes variations are negligible and only phase variations worsen the harvested array-gains. We show that the Fresnel region which covers the majority part of near-field, can be enlarged by a factor of four when considering possible imperfectness from a conventional two-dimensional (2D) far-field BF. Therefore, it is of interest to design analog 3D-BF than can recover array-gain losses in this region. Secondly, with the proved decomposition theorem we show that the optimal 3D-BF can be decomposed into a 2D far-field BF and a one-dimensional (1D) near-field BF. The 2D far-field BF compensates phase variations from mismatches in the azimuth and elevation angles, while the 1D near-field BF compensates remaining phases variations caused by distance differences from the UE to different antenna-elements on LIS. Such a proposed “2D+1D” BF design reduces codebook size significantly and is fully compatible with the existing far-field BF in the fifth-generation new-radio (5G-NR) system. Thirdly, we analyze an optimal codebook design for the 1D near-field BF, and show that with a small codebook it can perform close to optimal. Numerical results further verify that our proposal is effective and robust to recover array-gains in the near-field of LIS. </p>
Multisensed Emotions as Adaptation Controllers in Human-to-Serious NeuroGames Communication
Authors: Dias Sofia , Jelinek Herbert , Hadjileontiadis Leontios 
Published: March 2023

<p>Emotion is defined (from Britannica) as a complex combination of experiences of consciousness, bodily sensation and behavior, reflecting personal significance of externally and/or internally triggered changes. As an indispensable part of human communication, emotions could be represented within the digital world as means that could control the human interaction with the digital artifacts. When this is combined with gamification, a more engaging communication for the player could be established. In this article, we explore how multisensed emotions of players could be used as adaptation controllers within the emotion-aware serious neurogames (SNGs). We first briefly describe the emotion sensing and recognition landscape, examining the emotion-source sensing and emotion inferring approaches. We then discuss the SNGs design framework and the way human-to-SNG communication is set. Additionally, we describe the way the adaptation of the SNG characteristics can be driven by the inferred emotions, towards the achievement of the desired SNG goals. In addition, we demonstrate the feasibility and design characteristics of such multisensed emotion-aware SNGs, by presenting a related application case, namely EmoSense, and evaluate its acceptance as a technological solution in the field of neurofeedback. Finally, we discuss challenges and opportunities in the field. </p>

A Passivity-Based Small-Signal DEF Analysis for Low Frequency Oscillation Source Characterization of VSC-HVdc
Authors: Chatterjee Kaustav , Samanta Sayan , Chaudhuri Nilanjan Ray 
Published: March 2023

<p>In bulk power systems, detecting the sources of low-frequency oscillations is a challenging problem. Among the techniques available, the dissipating energy flow (DEF) method has emerged as a promising tool with notable success with real-world oscillation cases. While the mathematical justifications for the method's characterization of a device as an oscillation source (or sink) is well-studied for synchronous generators and standalone inverters, no insights have been developed for power-electronics-interfaced dc transmission systems. To fill this gap, this paper presents a theoretical analysis of the DEF in a voltage source converter-based high voltage direct current (VSC-HVdc) system. Passivity-based analysis is performed to explain why a VSC-HVdc system, operating at unity power factor, with the commonly used control strategy involving constant real power control, dc-link voltage control, and ac voltage -- reactive power droop control or constant reactive power control is a source of oscillation energy. Supporting case studies are performed on the IEEE 4-machine and 16-machine test systems. </p>

Published: March 2023

<p>Tracking targets moving in noisy environments via noisy observations is of crucial importance for various civilian and military applications. This involves, among other tasks, ascertaining the state of a target at a next time instant, called as track prediction, and combining the predicted state with a noisy observation to obtain an updated state at the current time instant, called as track correction. We consider track prediction and correction tasks of a radar target tracking application in a highly maneuvering scenario where the targets exhibit motion in a 3-dimensional space under randomly changing constant velocity, acceleration and turn models. The detections from the targets are available at irregular time intervals. We pose the problem of prediction (correction) as a time-series regression problem where several past detections along with their time stamps are used as input, and the next (respectively, current) detection is used as the expected output. We obtain temporal convolutional network (TCN) based models for prediction and correction, which are shown to perform significantly better than the classical pre- fixed interacting multiple model (IMM) algorithm under various different scenarios in terms of mean squared error between the true and predicted/corrected values, especially during model transitions and ascend/descend phases with manoeuvres. </p>

Published: March 2023

<p>Activity recognition, e.g., identifying individuals, recognizing their physical activities, or estimating their number in a room, based on WiFi's Channel State Information (CSI) has been studied intensively in the last decade. </p>
<p>While most existing works consider analyzing CSI data from a single person in a rather constrained environment, almost none of them has been successful in generalizing these results to unconstrained, real-world environments, in particular, when multiple individuals are present. </p>
<p>In this paper, to address this problem, we introduce a fully annotated dataset ($\approx$ 70 GB of data) containing CSI and environmental data collected from two real-world offices over multiple days of continuous monitoring. To the best of our knowledge, this is the first freely available dataset of its kind. </p>
<p>On the one hand, our dataset evidences that vastly disregarded {\em implicit changes} in the environment -- due to small objects being repositioned, added or removed -- are the main reason for the lack of generalizability by existing approaches. On the other hand, we expect it to promote further research work in this area and, thereby, to facilitate general solutions for CSI-based activity recognition in real-world environments.</p>
