Decentralised strategy for energy management of collaborative microgrids using multi‐agent system
Authors: El Zerk Abdallah , Ouassaid Mohammed , Zidani Youssef 
Published: July 2022

AbstractIn this study, the concept of collaborative microgrids (MGs) with shareable resources is introduced. The developed concept enables the householders of an isolated district or neighbourhood to cooperate and communicate intelligently in order to establish a reliable and proprietary MG. Therefore, a multi‐agent system solution for a distributed energy management system is designed. The proposed approach should first supply households while maintaining MG stability. Second, it offers designers decent programing flexibility and ensures system adaptability when households are added or removed. Three agents are developed, the nanogrid (NG) agent which handles the centralised energy management of the NG and messages the Master agent with the necessary information. The Master agent is responsible for the decentralised management of energy over the microgrid and controls the switches. The management strategy using multi‐agent systems aims to encourage customers considered as NG to contribute energy to the MG. The strategy relies on the implementation of a point‐based remuneration model in which the collected points depend on the contribution. The results highlight the importance of the proposed approach, which can be exploited to connect and supply isolated facilities intelligently.

Context.Spectroscopic data are necessary to break degeneracies in the asteroseismic modelling of the interior structure in high- and intermediate-mass stars. With the TESS mission, the number of bright intermediate-mass B-type stars with long photometric light curves that are suitable for detailed asteroseismic studies has increased substantially compared to the pre-TESS era.Aims.We derive precise photospheric stellar parameters for a sample of 166 B-type stars with TESS light curves through a homogeneous spectroscopic analysis. The variability types of these sample stars are also classified based on all currently available TESS sectors, and they are ultimately prioritised according to their astrophysical potential.Methods.We obtained high-resolution spectra for all 166 targets with the FEROS spectrograph in the context of a large program. The spectra were reduced with the CERES pipeline, which we adapted to improve the quality of the reduced spectra. These spectra were subsequently analysed with ZETA-PAYNE, a machine-learning-based spectrum analysis algorithm, to infer precise stellar labels for all stars in the sample. Furthermore, the least-squares deconvolution (LSD) method was employed to investigate spectral line profile variability (LPV) and isolate binary systems from presumably single stars.Results.The LSD profile analysis identified 26 spectroscopic double-lined binaries; the remainder of the sample are 42 supergiants in the Large Magellanic Cloud galaxy and 98 Galactic stars, both with and without apparent LPV. For the Galactic single stars and single-lined spectroscopic binaries, we determine their five main surface parameters: effective temperature (Teff), surface gravity (logg), global metallicity ([M/H]), projected rotational velocity (vsini), and microturbulent velocity (ξ) with average formal precisions of 70 K, 0.03 dex, 0.07 dex, 8 km s−1, and 0.7 km s−1, respectively. The average internal uncertainties we find for FEROS spectra with our spectrum analysis method are 430 K(Teff), 0.12 dex (logg), 0.13 dex ([M/H]), 12kms−1(vsini), and 2 kms−1(ξ).Conclusions.We find spectroscopic evidence that 8 of the 98 galactic single or SB1 variables are fast-rotating gravity-mode pulsators occurring in between the slowly pulsating B (SPB) stars andδScuti instability strips. Theg-mode frequencies of these pulsators are shifted to relatively high frequency values due to their rotation, and their apparently too lowTeffrelative to the SPB instability region can in most cases be explained by the gravity darkening effect. We also discover 13 new HgMn stars in the Galactic sample of which only one is found in a spectroscopic binary, resulting in a biased and therefore unreliable low binary rate of only 8%.
Higher differentiability results in the scale of Besov Spaces to a class of double-phase obstacle problems
Authors: Giuseppe Grimaldi Antonio , Ipocoana Erica 
Published: July 2022

We study the higher fractional differentiability properties of the gradient of the solutions to variational obstacle problems of the form
$\min \left\{ {\int_\Omega {F\left( {x,w,Dw} \right){\rm{d}}x\,:\,w\, \in \,{\kappa _\psi }\left( \Omega \right)} } \right\},$
with F double phase functional of the form
$F\left( {x,\,w,\,z} \right) = b\left( {x,w} \right)\left( {{{\left| z \right|}^p} + a\left( x \right){{\left| z \right|}^q}} \right),$
where Ω is a bounded open subset of ℝn, ψ ∈ W1,p(Ω) is a fixed function called obstacle and = {w ∈ W1,P(Ω) : w ≥ ψ a.e. in Ω} is the class of admissible functions. Assuming that the gradient of the obstacle belongs to a suitable Besov space, we are able to prove that the gradient of the solution preserves some fractional differentiability property.

ZusammenfassungDie Kurzform des Bielefelder Fragebogens zu Partnerschaftserwartungen (BFPE12)
misst drei partnerbezogene Bindungsskalen: Akzeptanzprobleme,
Öffnungsbereitschaft und Zuwendungsbedürfnis. Die vorliegende
Studie untersuchte Messinvarianz und Validität des BFPE12 anhand einer
klinischen (N=102) und einer nicht-klinische Stichprobe
(N=106). Neben dem BFPE12 wurden erhoben: Kurzform des
Experiences in Close Relationships – Revised (ECR-RD8), Outcome
Questionnaire (OQ-30), revidiertes Beck-Depressions-Inventar (BDI-II),
Soziale-Phobie-Inventar (SPIN) und
Prüfungsängstlichkeitsinventar (TAI-G). Die Faktorenstruktur
wurde mittels konfirmatorischer Faktorenanalyse (CFA), die interne Konsistenz
der Skalen mittels McDonald’s ω, die Messinvarianz mittels eines
Zwei-Gruppen-Strukturgleichungsmodellen und die Validität mittels
Korrelations- und Regressionsanalysen untersucht. Die Faktorenstruktur konnte in
beiden Stichproben bestätigt werden (CFI>0,93; TLI>0,93;
RMSEA<0,08; SRMR<0,08). Die Reliabilität der drei Skalen
war in beiden Stichproben akzeptabel (ω>0,7) – mit
Ausnahme des Zuwendungsbedürfnisses in der nicht-klinischen Stichprobe.
Modellvergleiche legen konfigurale, metrische und skalare Messinvarianz bzgl.
des Faktors klinisch versus nicht-klinisch nahe. Im Sinne der konvergenten
Validität waren Akzeptanzprobleme und Zuwendungsbedürfnis
erwartungskonform mit bindungsbezogenen Ängsten
(r=0,771und r=0,539, p<0,001) und
geringe Öffnungsbereitschaft mit bindungsbezogener Vermeidung
(r=− 0,704, p<0,001) assoziiert.
Insgesamt ist der BFPE12 als reliables und valides Instrument zur Messung
partnerschaftlicher Bindungsaspekte in klinischen und nicht-klinischen
Stichproben zu bewerten.

Abstract
Objective In our study, we aimed to summarize the etiology of subdural hematoma that was not traumatic and required operation in pediatric patients. The subdural hematoma characteristics, possible etiologies, and treatment, as well as the patient outcomes, were analyzed.
Methods A retrospective examination was made of pediatric patients with subdural hematoma who were operated on at Ümraniye Training and Research Hospital. Patients with a history of trauma were excluded. Data on patient sex, age, bleeding location, type of hematoma based on computed tomography imaging, surgical treatment, presenting symptoms, presence of comorbidities, Glasgow Coma Scale, thrombocyte counts, and international normalized ratio values were recorded.
Results Of the 19 patients included in the study, 4 were female and 15 were male. Their ages ranged between 0 and 15 (mean = 5.84) years. In 57.8% of the patients, comorbidities, including acute myeloid leukemia, a history of shunt operation, epilepsy, mucopolysaccharidosis, known subdural effusion, autism, coagulopathy, ventricular septal defect/tetralogy of Fallot, cerebrospinal fluid leakage after baclofen pump administration, Marfan's syndrome, and late neonatal sepsis were present, while 21% had arachnoid cysts and 21% had no reported comorbidities.
Conclusion This study suggests that, in pediatric patients with subdural hematoma with an amount of bleeding requiring surgical management, any underlying comorbidities should be investigated regardless of the presence of a history of trauma. While investigating systemic diseases, special attention should be paid to the presence of arachnoid cysts or disruption in cerebrospinal fluid dynamics along with a history of hematologic diseases.

Resumo
Objetivo Analisar a incidência da necrose avascular da epífise no tratamento do escorregamento da epífise proximal do fêmur pela técnica de Dunn modificada, correlacionando-a com outras variáveis. Como objetivo secundário, descrevemos outras complicações encontradas.
Métodos Estudo retrospectivo com 20 pacientes tratados entre 2009 e 2019, com seguimento de 2 a 12 anos, tratados pela mesma equipe cirúrgica. A análise incluiu características gerais, tempo entre apresentação e procedimento cirúrgico, classificação, presença de perfusão sanguínea intraoperatória da epífise, avaliação das complicações e seus respectivos tratamentos.
Resultados Todos os casos eram graves, 65% crônicos agudizados e 55% dos escorregamentos eram instáveis. Nossa taxa de complicações foi de 45%, sendo 5 casos de necrose avascular, 2 de infecção profunda, uma falha do material e uma instabilidade articular. Pacientes operados com maior tempo após a internação e os sem perfusão intraoperatória da epífise tiveram maior risco de necrose na análise estatística. Considerando o tempo do estudo, tivemos 4 casos de necrose nos primeiros 5 anos e 1 caso nos últimos 5 anos.
Conclusão Nosso estudo demonstrou que a necrose foi a complicação mais comum e que o atraso para a realização da cirurgia e a ausência de perfusão da epífise no intraoperatório podem predispor à necrose avascular. Embora não estatisticamente significante, a instabilidade coxofemoral foi observada na forma de apresentação crônica e a fixação cirúrgica com fios rosqueados se mostrou menos eficaz que a fixação com parafuso canulado.Este procedimento deve ser reservado para casos graves nos quais outras técnicas não sejam possíveis e realizado por equipe experiente, treinada e capacitada.

Resumo
Objetivo O presente estudo estimou a proporção de avascularidade histológica das extremidades das fraturas em caso de pseudoartrose de ossos longos.
Métodos No total, 15 casos de pseudoartrose quiescente estabelecida foram operados de acordo com o protocolo padrão e as extremidades da fratura foram avaliadas histologicamente. Em resumo, o tecido biopsiado foi fixado em formalina e embebido em parafina (FFPE); secções de 5 mícrons foram coradas com hematoxilina e eosina de acordo com os protocolos padrões. A imunohistoquímica com anticorpo anti-CD31 (clone JC70A, DBS) foi realizada manualmente segundo protocolos padrões.
Resultados Todos os casos de pseudoartrose quiescente foram incluídos; 2 eram de pseudoartrose oligotrófica e 13 eram de pseudoartrose atrófica à radiologia. Destes, 20% eram de pacientes do sexo feminino, 40% de indivíduos entre 31 e 40 anos de idade e todos os casos eram de pseudoartrose atrófica à radiologia. Todos os casos eram positivos para CD-31 à imunohistoquímica. A densidade dos vasos sanguíneos era de categoria I em 13,33% dos casos e de categoria II em 86,67%. Quatro casos apresentavam inflamação branda e dois apresentavam inflamação moderada. O número médio de vasos era de 10 por campo de alta potência na faixa etária de 20 a 30, de 31 a 40 e de 41 a 50 anos. A faixa etária de 61 a 70 anos apresentava, em média, 4 vasos por campo de alta potência. A diferença nos números de vasos em pseudoarthroses oligotróficas e atróficas não foi significativa. Não houve correlação entre a densidade de vasos e a duração da pseudoartrose.
Conclusão A nomenclatura de classificação da pseudoartrose em atrófica, oligotrófica e hipertrófica precisa ser revista. Nossos achados não indicam que a pseudoartrose atrófica e oligotrófica sejam histologicamente diferentes.
Thrombotic Thrombocytopenic Purpura: From 1972 to 2022 and Beyond
Authors: George James N. 
Published: July 2022

AbstractThis review tells the story of my personal experience with thrombotic thrombocytopenic purpura (TTP). It begins with my first encounter with TTP 50 years ago when 2 sisters presented 2 years apart, both pregnant and both died. At that time, I knew nothing about hereditary TTP (hTTP), the risks of pregnancy, or effective treatments. In 1991, a year after I moved to Oklahoma, therapeutic plasma exchange (TPE) was established as an effective treatment. With the availability of effective treatment, the number of patients presenting with suspected TTP soared. The diagnosis of TTP was imprecise. I worked with the Oklahoma Blood Institute (OBI) to understand the management of TTP. Because the OBI provided all TPE procedures for most of Oklahoma, we saw all consecutive patients within a defined geographic area who were identified at a uniform time early in the course of their TTP, without selection or referral bias. It was an inception cohort; this became the Oklahoma TTP Registry. In 2001, we began a very successful collaboration with the University of Bern, Switzerland, to measure ADAMTS13 activity in all of our patients. From our patients, we learned that acquired, autoimmune TTP (iTTP) is a chronic disease with risks for cognitive impairment and depression. Recognition in 2012 of three sisters with hTTP was reminiscent of the beginning of my story. hTTP has risks for multiple severe morbidities, beginning at birth and especially during pregnancy. Future management of both iTTP and hTTP will be more effective and more convenient.

Resumo
Objetivo Investigar a eficácia do fator de crescimento epidérmico (EGF) recombinante humano na cicatrização da lesão do manguito rotador no ombro de coelhos.
Métodos As rupturas do manguito rotador (RMRs) foram criadas experimentalmente em ambos os ombros de 20 coelhos Nova Zelândia. Os coelhos foram divididos nos seguintes grupos: RMR (grupo controle; n = 5), RMR + EGF (grupo EGF; n = 5), RMR + reparo transósseo (grupo reparo; n = 5) e RMR + EGF + reparo transósseo (grupo reparo combinado + EGF; n = 5). Todos os coelhos foram observados por 3 semanas, e amostras de biópsias foram coletadas do ombro direito na 3ª semana. Após mais 3 semanas de observação, todos os coelhos foram submetidos à eutanásia, e uma amostra de biópsia foi coletada dos ombros esquerdos. Todo o material de biópsia foi corado com hematoxilina e eosina (H&E) para avaliação de vascularidade, celularidade, proporção de fibras e número de células fibrocartilaginosas à microscopia óptica.
Resultados O grupo reparo combinado + EGF apresentou a maior quantidade e a sequência mais regular de colágeno. O grupo reparo e o grupo EGF apresentaram maior atividade fibroblástica e formação capilar em comparação ao grupo controle, mas a maior atividade fibroblástica e a formação capilar com maior vascularidade foram detectadas no grupo reparo combinado + EGF (p < 0,001). O EGF parece melhorar a cicatrização da ferida no reparo da RMR. A aplicação isolada de EGF, mesmo sem cirurgia reparadora, parece melhorar a cicatrização da RMR.
Conclusão Além do reparo da RMR, a aplicação de EGF recombinante humano auxilia a cicatrização do manguito rotador dos ombros de coelhos.

Dynamical conductance measurement of single molecular junctions with both high-speed and high-precision

Real-time and rapid monitoring of the electron transport in nanoscale structures is critical for understanding many fundamental phenomena. However, it is not possible to rapidly record the dynamical current that varied across several orders of magnitude by using a typical linear low-noise current-to-voltage converter due to its fixed gain. In addition, it faces a great challenge in carrying out a dynamical small current measurement by using a commercial source-monitor unit device with both high-precision and high-speed because a high-precision measurement normally requests long integration time, while high-speed sampling demands short integration time. To overcome these challenges, we designed a measurement system with an integrated logarithmic amplifier, which can convert the current/conductance signal (varied across eight orders of magnitude) into an output voltage signal (varied within only one order of magnitude). We successfully applied it for the dynamical conductance measurement of single molecular break junctions in which the current rapidly changed from milliampere (mA) to picoampere (pA) within tens of milliseconds under a fixed bias voltage. It is demonstrated that the intrinsic conductance can be determined accurately independent of the applied bias and the real-time dynamical conductance traces can be precisely recorded with a high-speed sampling ratio. This logarithmic amplifier design and home-made measurement system provide a way to realize a fast measurement (30 kHz) for a rapidly varied current (mA–pA), making it suitable for the characterization of single-molecule junctions during the break process, and show potential for a wide application far beyond molecule electronics.

Context The rhizosphere is an environment created by interactions between root exudates and microorganisms. Interactions are beneficial due to certain components having a plant growth promoting rhizobacteria (PGPR) effect. Aims This study consists of the isolation, screening of PGPR from the rhizosphere of Olea europaea L. of a Mediterranean climatic region in Algeria and the study of their effects on growth of two agronomic vegetables Phaseolus vulgaris L. and Cucurbita pepo L. Methods Based on their ability to produce the PGPR molecules indole-3-acetic acid (IAA), phosphatase and siderophores, three rhizobacteria (S25, S75, and S79) were chosen for in vivo tests and capacity to produce the cell wall degrading enzymes chitinase, lipase, protease, glucanase, cellulase, and and phospholipase. They were also examined using scanning electron microscopy (SEM) and analysed using matrix-assisted laser desorption/ionisation time of flight mass spectrometry (MALDI-TOF MS) for identification. Key results Bacterial strains identified as Bacillus cereus and Bacillus thuringiensis were able to enhance significantly germination of the two vegetables at P < 0.001. Vegetative parameters of C. pepo were significantly affected by the bacterial inoculation. We noted increases in stem length (P < 0.05), number of flowers (P < 0.01), and root length (P < 0.001). Conclusion The bacterial isolates of this study provide biological options in treatments originating from alternate hosts. Implications They provide hope for companion/intercrop planting schemes, leading to optimisation of agricultural yields in agroecological blends.
