AbstractThis study reports that photodetectors based on double‐layer ZnO nanorods grown on AZO seed layer by hydrothermal method. Compared with the photodetectors with single‐layer nanorods, the on/off ratio of the photodetectors with double‐layer ZnO nanorods is increased by ∼2.52 times, the photoresponsivity is increased ∼5.50 times, the sensitivity is increased ∼3.34 times and the response time was shortened by 0.97 and 6.65 s, respectively. Furthermore, the photocurrent derivative also shows that the photodetectors based on double‐layer ZnO nanorods has a faster response speed.
Research on rotor unbalance magnetic pull compensation method based on modular winding d‐axis current injection
Authors: Zhang Jiaxu , Zhang Bingyi , Feng Guihong 
Published: November 2021

AbstractDue to the dual air‐gap topology of the direct‐drive permanent magnet motor with inner enhance force (IEF‐DDPMM), the radial EM exciting force generated in the inner and outer air gaps when the rotor is eccentric will act on the same rotor, and the unbalanced magnetic pull (UMP) on the rotor will reduce the fatigue life of the rotor structure and bring many problems such as vibration and noise. Therefore, the rotor UMP compensation method of IEF‐DDPMM based on modular winding d‐axis current injection is proposed to suppress the harm caused by eccentricity. The expression of electromagnetic (EM) exciting force considering the cogging effect and current time harmonic without rotor eccentricity faults is derived by the analytical method. Also, the EM exciting force newly introduced due to the rotor eccentricity is analysed. The effects of different eccentricity types on torque characteristics, the fatigue life of the rotor structure and stator vibration of IEF‐DDPMM are compared and analysed by the FEM. Finally, the IEF‐DDPMM rotor eccentricity models are optimised based on the method. The performance of the motor before and after rotor UMP compensation is evaluated by FEM. The results show that the proposed method is correct and effective.

Published: November 2021

AbstractThe reform of power spot market in China provides a new profit mode, determining energy trading strategy based on the power spot prices for distributed energy storages. However, individually accessing every distributed energy storage to the dispatch centre results in a high cost and low efficiency, which needs to be improved by connecting through the aggregator. To this end, this paper proposes a regulation mode and strategy for distributed energy storages participating in energy trading through aggregation. First, the optimal centres of distributed energy storages are searched as the aggregation centres according to the electrical distance distributed by the energy storage, and the model of each distributed energy storage aggregation group is established. On this basis, the conditional value at risk (CVaR) method is introduced to quantify the income risk brought by the fluctuation of power spot prices, following with the optimization model for day‐ahead stage and real‐time stage. Finally, case studies under multiple scenarios of power spot market verify that the regulation mode and strategy can effectively guarantee the economic profits of distributed energy storages by setting aggregation groups and reasonable risk preference coefficients.

The objectives of our work were to establish the epidemiological and bacteriological profile of female urinary tract infection at the Mohammed VI University Hospital of Oujda (Morocco), and then to study the drug resistance of the bacterial strains isolated. This is a retrospective study over 36 months including urine samples from patients hospitalized or consulting at the CHU Mohamed VI of Oujda (Morocco). Urines were processed according to the recommendations of the Medical Microbiology Reference (REMIC) and the EUCAST (European Committee on Antimicrobial Susceptibility Testing).
We collected 12556 requests for CBEU from different departments. At the top of the list was the emergency department with a rate of 37% (n= 4666) followed by outpatient clinics (33.1%; n=4226). 5% (n=630) of the CBEU were positive. Escherichia coli (E. coli ) dominated the epidemiological profile with a rate of 72.50% (n=482). E. coli was resistant to penicillins in 69.50% (n=299) of cases, protected penicillins in 34.80% (n=149), third generation cephalosporins (C3G) in 9% (n=38), fluoroquinolones in 17.5% (n=73), Trimethoprim-Sulfamethoxazole in 46% (n=196) of cases and gentamicin in 12% (n=51) of cases. None of the strains were resistant to carbapenems.
Awareness-raising on the proper use of antibiotics, issuing national recommendations for the treatment of urinary tract infections in order to standardize therapeutic regimens. Effective control of these infections requires a global prevention strategy that implies close collaboration between epidemiologists, clinicians, bacteriologists, hygienists and the health care team.

SummaryEntgiftungskonzepte sind in der Naturheilkunde unverzichtbar. Die Therapie kann jedoch unwirksam sein oder sogar Schaden anrichten, wenn der Organismus nicht bereit ist zum Entgiften. Mit gezielter Anamnese und Diagnose können Behandelnde herausfinden, ob vor der Entgiftung eine allgemeine und/oder spezifische Aufbautherapie notwendig ist. Neben Präparaten für zum Beispiel die Stärkung einzelner Organe kommen für eine Aufbautherapie unter anderem Segmentbehandlungen und Lebensstiländerungen infrage.

Abstract
Background Several treatment options for chronic periprosthetic joint infections have been published in the current literature, with an on-going discussion to determine effective
management algorithms.
Objectives To compare outcomes of the two-stage exchange procedure in revision TKA prior to and after implementation of the PRO-IMPLANT Foundation treatment algorithm. The primary
endpoints were defined as (i) revisions during the interval time, (ii) duration of the interval time and (iii) successful PJI eradication.
Material and Methods Between 02/2013 and 09/2016, 122 patients were included in a single-centre cohort analysis. 55 patients were treated according to the previously used algorithm
(K1) and 67 according to the PRO-IMPLANT Foundation algorithm (K2). A minimum follow-up period of 3 years was set as the inclusion criterion. Successful eradication of infection was defined
in accordance with the consensus criteria by Diaz-Ledezma et al.
Results Successful eradication was achieved in 42 (67%) patients in K1 and 47 (85.5%) in K2 (p ≤ 0.005). The mean interval time was 88 days (range 51 – 353) in K1 and 52 days (range
42 – 126) in K2 (p ≤ 0.005). In K1, a mean of 0.8 (range 0 – 6) revisions were necessary during the interval period compared with 0.5 (range 0 – 4) in K2 (p = 0.066).
Conclusion Implementation of the PRO-IMPLANT treatment algorithm led to significant improvement in the outcome of periprosthetic joint infections. During mid-term follow-up,
infection eradication was highly successful, with decreases in the interval time as well as the number of revisions.

Published: November 2021

ZusammenfassungNoch immer sorgt die Kontrastmittelgabe bei Patienten mit Niereninsuffizienz für regelmäßige Diskussionen im klinischen Alltag. Sowohl Röntgen- als auch MR-Kontrastmittel werden überwiegend renal eliminiert und sind somit eng an die Nierenfunktion gekoppelt. Basis der Risikostratifizierung vor Kontrastmittelgabe ist die Bestimmung der eGFR. Patienten mit einer eGFR ≥ 30 ml/min benötigen eine individuelle Risikobeurteilung. Bei fortgeschrittener Niereninsuffizienz liegt das Hauptaugenmerk auf der Gewährleistung der Euvolämie. Evidenz für anderweitige Präventionsansätze findet sich aktuell nicht, weitere spezifische Maßnahmen zur Prävention einer Kontrastmittel-assoziierten Nierenschädigung sind bei heutigen Kontrastmitteln somit nicht angezeigt. Eine zeitliche Abstimmung von Kontrastmittelgabe und Dialysesitzung bei terminaler Niereninsuffizienz ist nur nach Kontrastmittel-gestützten MRT-Untersuchungen zu beachten. Eine Sonderrolle stellt nach wie vor die akute Nierenschädigung dar.

Published: November 2021

Abstract
Objectives To investigate the posttreatment apical periodontitis (AP) in endodontically treated teeth through a multivariate approach and to analyze the relative importance of quality and type of coronal restoration as predictors of periapical disease.
Materials and Methods The present study sample was drawn within 2-year period from the 1,072 consecutive patients older than 18 years, first time attending the Dental Clinic of the Clinical Hospital Center Rijeka, Croatia. A total of 1,350 endodontically treated teeth were included in the study. For each tooth, the periapical status, root filling quality, intracanal post, separated file presence, marginal bone loss, and quality and type of coronal restoration were recorded.
Statistical Analysis Chi-square tests were used to analyze the variations in the periapical status, quality of root canal filling, and quality of coronal restoration in different tooth types. The effect of explanatory variables on periapical status was explored using univariate and multivariate logistic regression models. The outcome variable was set as the presence versus absence of AP in the tooth.
Results Multivariate logistic regression analysis revealed statistically significant associations and increased risk for AP presence in molars (odds ratio [OR] = 2.15; p < 0.001), teeth positioned in mandible (OR = 1.49; p = 0.007), teeth with short length of root filling (OR = 4.08; p < 0.001), overfilled teeth (OR = 2.99; p = 0.001), and teeth with inadequate density of root filling (OR = 4.14; p < 0.001). Considering variables related to coronal restoration, neither coronal restoration type nor quality was found to be predictive for posttreatment AP. Merely, the presence of intracanal post significantly increased the odds of AP presence (OR = 1.57; p = 0.009).
Conclusion The results of the present study did not indicate that type or quality of coronal restoration may be predictors of posttreatment AP. Periapical disease was significantly associated with molars, mandibular teeth, substandard quality of root fillings, and intracanal post presence.

AbstractInfantile systemic hyalinosis is a very rare fatal autosomal recessive genetic disorder with a mutation in capillary morphogenesis gene-2-CMG2/Human anthrax toxin-2 ANTXR2 resulting in spindle cell proliferation, altered collagen metabolism along with extensive deposition of hyaline material in the skin and several tissues. To date only a few cases have been reported in the literature, hence we reported this series. This study is a retrospective chart review of infants diagnosed with infantile systemic hyalinosis from January 2015 through December 2020 at a tertiary care children's hospital in South India. The mean age of presentation was 9.4 months, with a male to female ratio of 1:5. All children were born of consanguineous marriage except one child. All children had symptoms at birth, painful limb movements, multiple joint stiffness, gingival thickening, skin lesions around perianal, perioral areas, and frog-like position. Three (50%) children had stiff skin. Routine tests including complete blood count, liver function test, renal function test, creatine phosphokinase, nerve conduction studies, and metabolic tests were normal in all children. Skin biopsy showed hyalinized collagenous tissue in the dermis. Genetic study results of two cases revealed pathogenic variants in ANTXR2 gene. Infantile systemic hyalinosis should be considered in infants presenting with painful limb movements. The diagnosis helped in avoiding unnecessary investigations and prognostications. The genetic information from proband mutation helped in prenatal diagnosis in two families.

AbstractThe prenatal diagnosis of congenital heart disease (CHD) is important because of mortality risk. The onset of CHD varies, and depending on the malformation type, the risk of aneuploidy is changed. To identify possible genetic alterations in CHD, G-banding, chromosomal microarray or if needed DNA mutation analysis and direct sequence analysis should be planned.In present study, to identify genetic alterations, cell culture, karyotype analysis, and single nucleotide polymorphism, array analyses were conducted on a total 950 samples. Interventional prenatal genetic examination was performed on 23 (2, 4%, 23/950) fetal CHD cases. Chromosomal abnormalities were detected in 5 out of 23 cases (21, 7%). Detected chromosomal abnormalities were 10q23.2 deletion, trisomy 18, 8p22.3-p23.2 deletion, 8q21.3-q24.3 duplication, 11q24.2q24.5 (9 Mb) deletion, and 8p22p12 (16.8 Mb) deletion. Our study highlights the importance of genetic testing in CHD.

Published: November 2021

Abstract
Background Single nucleotide polymorphisms (SNPs) in vascular endothelial growth factor A (VEGFA) are associated with susceptibility to several diseases including cancer. Correlations between VEGFA rs3025020 genotypes with clinical and laboratory features of primary myelofibrosis (PMF) are unstudied.
Methods DNA was analyzed by real-time polymerase chain reaction for VEGFA rs3025020 genotypes in a cohort of 844 subjects with PMF and in two cohorts of normal subjects (N = 247 and N = 107).
Results Frequency of rs3025020 minor allele (T) was not significantly different in subjects with PMF compared with normals; however, the T-allele was more frequent in PMF subjects with a calreticulin (CALR)-mutated genotype compared with normals (35 vs. 27%; OR = 1.47 [95% CI, 1.09, 1.98] p = 0.011), especially in subjects with a CALR-type 2/type 2-like mutation (43 vs. 27%; OR = 2.01 [1.25, 3.24] p = 0.004). CALR mutants with the rs3025020 TT genotype had higher CXCR4 expression on CD34-positive blood cells, and those who carried CT/TT genotypes had lower platelet concentrations compared with other genotypes at diagnosis. Overall, subjects with the rs3025020 CT/TT genotype had a lower cumulative incidence of deep vein thrombosis in typical sites (1.6 vs. 4.2%; OR = 0.37 [0.15, 0.90] p = 0.029) and longer interval from diagnosis to first thrombosis (HR = 0.37 [0.14, 0.95] p = 0.039).
Conclusion Persons with PMF and the VEGFA rs3025020 minor T-allele are more likely to have a CALR mutation compared with other somatic driver mutations and lower cumulative incidence and hazard for deep vein thrombosis in typical sites.
Weak antilocalization in topological crystalline insulator SnTe films deposited using amorphous seeding on SrTiO3

Published: November 2021

Topological crystalline insulators (TCIs) promise spin-polarized or dissipationless transport, which can be controlled by crystal symmetry breaking through applied strain or electric field. To realize TCI devices with gate-controlled topological states, it is necessary to develop methods for depositing continuous and thin TCI films on substrates suitable for electric-field gating. Here, we present an optimized templating procedure for depositing single-orientation, continuous films of TCI SnTe on SrTiO3, which is an oxide with a wide bandgap and large dielectric constant suitable for gated devices. This process takes advantage of a thin SnTe template layer crystallized after amorphous deposition, with additional SnTe being grown by molecular beam epitaxy and monitored with in situ laser ellipsometry. Continuous, single-phase SnTe films with a (001) orientation relative to the SrTiO3 lattice are achieved. Magnetoconductivity measurements of SnTe films reveal a coexistence of weak antilocalization, consistent with topologically non-trivial states, and weak localization, consistent with trivial states from the bulk. This method of analysis may be suitable to analyze the magnetotransport characteristics of any topological material with carriers in both topological and trivial bulk states. The maximum phase coherence length is achieved for films thicker than 20 unit cells, which could be used for gated-SnTe devices.

Published: November 2021

The Mn3X (where X = Ga, Ge, Sn, etc.) compounds have appealing prospects for spintronic applications due to their various crystal structures and magnetic properties for the design of reliable high-density memories. However, controlled growth of high-quality Mn3X thin films remains challenging in material science. Here, we reported the controlled film growth of Heusler alloy Mn3Ge, which could crystallize in respective tetragonal and hexagonal structures. The tetragonal D022-type Mn3Ge film exhibits strong perpendicular ferromagnetic anisotropy, while the hexagonal D019-type Mn3Ge film indicates non-collinear triangular antiferromagnetic order. From our experimental observations of structure characterizations, magnetic properties, anomalous Hall effect, and magnetoresistance measurements, we realized the manipulation of spin orientations and topological features. Majority/minority spin polarized Fermi surface and density of states of both tetragonal and hexagonal Mn3Ge structures were investigated by density functional theory calculations. Our work not only opens up technology routes toward the development of Mn3X-based devices for applications in topological spintronics and spin-torque memories but also leads to engineer the physical properties for fundamental study.

Published: November 2021

Abstract
This article presents a methodological proposal for using the Linguistic Landscape (LL) to examine the intersection of
multilingualism and social class in urban settings. The article draws from a study that considered how patterns of linguistic diversity in
public signage in a mid-sized US city mapped onto socioeconomic levels. The main innovation for LL methodology is the study’s use of census
data and geographic information system (GIS) to increase representativeness using two main constructs (social class and linguistic
diversity). After presenting the project design, the challenge of creating representative mapping in the LL is considered, with the
solutions the research team generated. Finally, we discuss several practical issues specific to doing LL fieldwork in urban contexts:
access, safety, and photography.
Non-Hermitian Weyl semimetals: Non-Hermitian skin effect and non-Bloch bulk–boundary correspondence
Authors: Yang Xiaosen , Cao Yang , Zhai Yunjia 
Published: November 2021

Abstract
We investigate novel features of three-dimensional non-Hermitian Weyl semimetals, paying special attention to the unconventional bulk–boundary correspondence. We use the non-Bloch Chern numbers as the tool to obtain the topological phase diagram, which is also confirmed by the energy spectra from our numerical results. It is shown that, in sharp contrast to Hermitian systems, the conventional (Bloch) bulk–boundary correspondence breaks down in non-Hermitian topological semimetals, which is caused by the non-Hermitian skin effect. We establish the non-Bloch bulk–boundary correspondence for non-Hermitian Weyl semimetals: the topological edge modes are determined by the non-Bloch Chern number of the bulk bands. Moreover, these topological edge modes can manifest as the unidirectional edge motion, and their signatures are consistent with the non-Bloch bulk–boundary correspondence. Our work establishes the non-Bloch bulk–boundary correspondence for non-Hermitian topological semimetals.
