Abstract
The immunity conferred by SARS-CoV-2 vaccines and infections reduces the transmission of the virus. But it is not clear how the effect of immunity is shared between a reduction of the contagiousness and an increased protection against infection. To answer this question, we used a register of >50’000 SARS-CoV-2 positive index cases and their >110’000 declared contacts to estimate the association between secondary attack rate and immunity status (natural infection, vaccine, or both). Analyses were stratified per four SARS-Cov-2 variants and adjusted for index cases and contacts socio-demographic characteristics and the propensity of the contacts to be tested.
The reduction of the propagation conferred by immunity was mainly a protection of the contacts against infection rather than a diminution of the contagiousness of the index cases. The largest immunity effect was conferred for both by natural infection, especially when recent for the contacts. Although of smaller amplitude, the effect of vaccination for index, i.e. the reduction of contagiousness, was less affected by SarS-CoV-2 variant and time since vaccination than the effect for contacts, i.e. the increase of protection against infection. Indeed, vaccination offered protection against infection only if given less than 6 months before and only for the variants preceding omicron, while the vaccination kept moderately reducing the index infectivity during the omicron wave, even when given more than 6 months ago. Hybrid immunity (vaccination and infection) did not have increased effectiveness than recent infection. These findings support the idea that vaccination also protects others, and highlight the need for the implementation of non-personal interventions reducing Sars-CoV-2 propagation, such as ventilation or air filtration.
Kilohertz-frequency interferential current induces hypoalgesic effects more comfortably than TENS
Authors: Park DaHoon , Kim Yushin 
Published: February 2023

Abstract
This study aims to demonstrate the hypoalgesic effect of the tibial nerve using transcutaneous interferential-current nerve inhibition (TINI), which injects the kilohertz frequency produced by the interferential currents. Thirty-one healthy adults participated in this cross-over repeated measures study. The hypoalgesic effects of TINI were compared with transcutaneous electrical nerve stimulation (TENS). The washout period was 24 hours or more. Stimulus intensity was set at the pain threshold level. TINI and TENS were applied for 20 minutes each. The ankle passive dorsiflexion range of motion, pressure pain threshold (PPT), and tactile threshold were measured at the baseline, pretest, test (immediately before ceasing intervention), and posttest (30 min after ceasing intervention) sessions. After the interventions, the participants evaluated the level of discomfort for TINI and TENS on a 10 cm visual analog scale (VAS). As a result, PPT significantly increased compared to baseline in test and posttest sessions of TINI, but not in those of TENS. Also, participants reported that TENS was 36% more discomfort than TINI. In conclusion, we found that TINI inhibited mechanical pain sensitivity and that the inhibitory effect persisted long after electrical stimulation ceased. Our study also shows that TINI provides the hypoalgesic effect more comfortably than TENS.

Abstract
Despite their rarity, PIK3CA mutations in meningiomas have raised interest as potentially targetable, ubiquitous mutations owing to their presence in sporadic benign and malignant tumors but also in hormone-related cases. Using new genetically engineered mouse models, we here demonstrate that Pik3ca mutations in post-natal meningeal cells are sufficient to promote meningioma formation but also tumor progression in mice. Conversely, hormone impregnation, wether alone or in association with Pik3ca and Nf2 mutations, fails to induce meningioma tumorigenesis while promoting breast tumor formation. We then confirm in vitro the effect of Pik3ca mutations but not hormone impregnation on the proliferation of primary cultures of mouse meningeal cells. Finally we show by exome analysis of breast tumors and meninges that hormone impregnation promotes breast tumor formation without additional somatic oncogenic mutation but is associated with an increased mutational burden on Pik3ca mutant background. Taken together, these results tend to suggest a prominent role of Pik3ca mutations over hormone impregnation in meningioma tumorigenesis, the exact effect of the latter still to be discovered.
On the continuous mechanics first- and second-order formulations for non-equilibrium nucleation: Derivation and applications
Authors: Ferreira I. L. , Moreira A. L. S. 
Published: February 2023

Abstract
Nucleation and growth are phenomena that can be applied to several fields of science and technology. On the other hand, nucleation depends on the cooling rate, dislocating the equilibrium, as surface energy depends on the created and deformed surface area. The crystalline/glassy transition limit dependence on the thermal gradient is also analyzed. In this paper, under the continuum mechanics, first- and second-order non-equilibrium nucleation formulation models are derived, and a phase-change moving interface is considering the thermal field. Nucleation important variables will be plotted against the cooling rate for several nucleation angles. It will be coupled with a theoretical model for the molar-specific heat capacity of solids to analyze its dependence on nucleation kinetics.

Abstract
Objective Type 1 diabetes (T1D) has been associated with alterations of the gut microbiota. Here we investigate the cross-talk between the immune system and the intestinal microbiota in murine T1D.
Design To evaluate the modulation of T1D by gut microbiota, non-obese diabetic (NOD) mice were cohoused with the 116C-NOD B-cell transgenic model. To further explore the influence of the adaptive immune system of NOD and 116C-NOD models on their fecal microbiota, we studied the immunodeficient variants NOD.RAG-2-/- and 116C-NOD.RAG-2-/-, as well as a non-T1D-prone mouse control. The role of B and T cells in modulating the gut microbiota composition was analyzed via intravenous injection of lymphocytes. Only female mice were studied.
Results NOD cohoused with 116C-NOD exhibited a reduction of T1D incidence. This incidence decrease was associated with a shift from a Th1 to a Th17 immune response and was driven by intestinal microbiota changes. Moreover, T1D could be predicted by different gut bacterial signatures in each group of T1D-prone mice. The proliferation of segmented filamentous bacteria, known as immune modulatory organisms, was enabled by the absence of T lymphocytes in young NOD, 116C-NOD, and immunodeficient NOD.RAG-2-/- and 116C-NOD.RAG-2-/- at all ages. Conversely, Bifidobacterium colonization required the presence of lymphocytes and was boosted in a non-diabetogenic milieu. Finally, 116C-NOD B cells enriched the gut microbiota of 116C-NOD.RAG-2-/- in Adlercreutzia.
Conclusion Together, these findings evidence the reciprocal modulation of gut microbiota and the immune system in rodent models of T1D.

Abstract

Omnivorous insects make foraging decisions between plant and prey resources depending on their accessibility, availability, and nutritional value. This shapes the stability and complexity of foodwebs, but also pest control services in agroecosystems. The mirid bug Lygus pratensis is a common cotton pest in China, but it also feeds on a variety of prey species. However, little is known about how different types of available resources affect its fitness and foraging behaviour. In laboratory experiments, we measured the fitness (survival, longevity and fecundity) of L. pratensis fed with bean pod only, bean + Aphis gossypii nymphs, or bean + Helicoverpa armigera eggs, and we also conducted focal observations of its foraging behaviour when provided the latter two. Adding H. armigera to its diet increased its fitness (both survival and fecundity), while adding A. gossypii was marginally detrimental. The different diets did not affect the time spent walking (searching for food resources) or preying, but significantly affected the time spent sapping bean tissue depending on L. pratensis life stage. Nymphs spent more time sapping plant when provided with H. armigera than A. gossypii (possibly through higher efficiency of handling prey). In addition, adults spent less time sapping plant than did nymphs (possibly through good efficiency of handling A. gossypii mobile prey and due to higher protein requirements). This special case of life-history omnivory highlights the complexity of natural foodwebs, where a major pest at the juvenile stage may reduce pest damage by preying on other pests species at the adult stage.

Published: February 2023

Abstract
Objective: to estimate the frequency of Positive Maternal Mental Health (PMMH) interpretation levels in pregnant women who attended prenatal consultation and to identify their association with obstetric and psychosocial factors.
Methods: a cross-sectional study that included pregnant women who attended prenatal care at 12 or more weeks of gestation. The following scales were applied: Positive Mental Health Questionnaire (PMHQ), Goldberg Anxiety and Depression Scale, and Jong Gierveld Loneliness Scale.
Results: 702 pregnant women were evaluated; 634 (90.3%) had flourishing PMMH, and 68 (9.7%) had non-flourishing PMMH. Among the latter, all were at an intermediate level, and none were languishing. Flourishing PMMH was more frequent in adults (91.2%) than in adolescents (75.0%) and those with higher education (93.0%) than in those with basic education (83.9%). The PMHQ factors and global score correlated positively with maternal age and negatively with anxiety, depression, emotional, social, and general loneliness. Associated with a higher frequency of non-flourishing PMMH were: general loneliness OR:6.32[CI95%:3.38-11.82], social loneliness OR:5.98[CI95%:3.42-10.42], adolescence OR:3.47[CI95%:1.61-7.45], emotional loneliness OR:3.12[1.83-5.32], anxiety OR:2.14[CI95%:1.27-3.60], and depression OR:1.88[CI95%:1.09-3.25]. Less frequently: work occupation outside the home OR:0.41[CI95%:0.24-0.68], technical/technological studies OR:0.22[CI95%:0.08-0.60] and university OR:0.27[CI95%:0.10-0.71]. Preconception consultation, desired pregnancy, cesarean section, and fetal or neonatal death were not associated. In the adjusted model: general loneliness OR:3.02[CI95%:1.10-8.31], social loneliness OR:2.82[CI95%:1.38-5.79] and anxiety OR:1.93[CI95%:1.02-3.67], retained statistical significance.
Conclusion: nine out of ten pregnant women had flourishing PMMH, and none had languishing PMMH. None of the obstetric factors were associated with non-flourishing PMMH, but they were associated with general loneliness, social loneliness, and anxiety.

Abstract
Dynamic infrared emissivity (DIE) regulators, which can efficiently modulate infrared radiation beyond vision, have emerged as an attractive technology in energy and information fields. However, current DIE regulators are usually visibly opaque, which limits their applications involving broad-spectrum requirements or multispectral compatibility. Therefore, it is necessary to propose new DIE mechanism and develop the desirable fully transparent DIE regulators for dynamically regulating infrared emissivity and solar spectral properties independently, although highly challenging. Here, we demonstrate DIE regulators based on a novel DIE mechanism with high visible transparency (84.7%), large emissivity regulation (0.51 in 3–5 µm, 0.42 in 7.5–13 µm), fast response (< 600 ms), and long cycle life (> 104 cycles). This excellent performance is achieved by the reversible injection/extraction of electrons into/from aluminum-doped zinc oxide (AZO) nanocrystals to modulate infrared plasmonic in a capacitive-type device, and the DIE regulation is attributed to variation of carrier concentration in the depletion layer near the surface of AZO nanocrystals. This novel DIE regulation method and fully transparent DIE regulators provide great opportunities for the on-demand smart thermal management of buildings and spacecrafts, multispectral display and adaptive camouflage, and may in other infrared radiation related technologies.

Published: February 2023

Abstract
Background
Job security is one of the basic needs of nurses, and it significantly impacts their willingness to work. The effectiveness of job performance among nurses will reflect on the organization's performance by providing high-quality health services.
Aim
The main purpose of this study is to identify Jordanian nurses' perceptions of job security and employee performance and to compare these variables between governmental and private hospitals.
Method
The study utilized a descriptive, comparative cross-sectional design. It was conducted in two governmental and two private hospitals. A sample of 156 nurses was recruited conveniently to participate in the study. The Job security questionnaire and The Six-Dimension Scale of Nursing Performance were used to collect data.
Results
The mean value of the job security score was (3.26), reflecting a moderate level of job security. The employee performance score average was (2.68) reflecting a high level of job performance. Nurses working in private hospitals had significantly higher scores in terms of overall job security (t = -5.53, p < 0.001) and employee performance (M = 2.53, SD ± 0.53) than nurses working in governmental hospitals.
Conclusion
Nurses with moderate job security levels obtained high job performance scores. Private hospitals had higher job security and employee performance than governmental hospitals. Future research can look into the characteristics of Jordanian nursing work environments that might have contributed to the observed differences between job security and employee performance.

Abstract
Background: Clinical and research use of transcranial magnetic and direct current stimulation are becoming more common in Turkey. However, the opinions of the researchers and ethics committees about the ethical dimension of the issue differ. The aim of this study is to examine the ethical views of the researchers and committees and to review the legal procedures of the clinical and research NIBS applications in Turkey.
Methods: The data were collected from researchers working with NIBS, ethics committee representatives and official regulatory agency. The surveys prepared by researchers were sent to them, and an interview was conducted with the TİTCK-KAD representative. Quantitative analysis was performed for multiple-choice and short-answer questions, while thematic analysis was performed for open-ended answers.
Results: In the first survey, 99 researchers with a mean age of 38.9±10.5 years and most of them being female (65.65%) participated. 44.4% of the researchers were medical doctors, 21.21% were psychologists, 24.24% were other health professionals (mostly physiotherapists), and 10.10% were from other fields (engineers, educators, etc.). 94% of the researchers stated that the NIBS practitioner should undergo a standardized training. Different rates were obtained in the items related to the effectiveness of NIBS, self-administration, ethical and legal issues. It appeared that 94.37% of the researchers applied to the Clinical Research Ethics Committees in Turkey.
Conclusion: Researchers in Turkey agree on the clinical use and efficacy of NIBS. However, when it comes to improving cognitive and physical performance in healthy people, they are largely hesitant both in terms of efficacy and morality. This attitude is very similar to that of other researchers around the world. In terms of ethics committees, it is observed that local ethics committees are not sufficiently aware of the issue and that there are some differences in practice.
Imaging risk factors for predicting postoperative complications of intramedullary nailing for tibial fracture
Authors: He Miao , Fu Xufei , Zhang Xiaoxing , Hu Jianhua , Li Jie 
Published: February 2023

Abstract
Objective
The objective of this study was to analyze the ratio of fracture site diameter to tibial isthmus diameter (RFTI) as a predictor of postoperative complications, including malunion and delayed union, after tibial intramedullary nailing for middle and lower tibial fractures.
Methods
Data were collected from all adult patients older than 20 years of age who underwent tibial intramedullary nailing for middle and lower tibial fractures between January 2015 and January 2022 and were followed up for at least 1 year. Diabetes history, smoking history, fracture type, injury mechanism, surgical method, surgical approach, diameter of the medullary cavity at the fracture site, and diameter of the tibial isthmus were recorded. Logistic regression analysis was used to determine the variables affecting the occurrence of complications. RFTI was used to calculate the sensitivity and specificity of the parameters, and ROC curves were generated to establish RFTI thresholds for predicting complications.
Results
A total of 123 patients with middle and lower tibial fractures were treated with intramedullary nails. The mean age of the patients was 43.72 years (range, 21–81 years); 89 were males and 34 were females. Univariate logistic regression analysis showed that fracture type, open reduction surgery, superior patellar approach, and RFTI value were significantly correlated with postoperative complications after intramedullary nailing of a tibial fracture. Multivariate logistic regression analysis showed that the RFTI value was an independent risk factor for complications (P = 0.001*). By using the RFTI values as predictors of complications, a ROC curve was generated to establish a threshold. The ROC curve showed that a RFTI value ≥ 1.31 had a sensitivity of 0.89, a specificity of 0.71 and an area under the ROC curve of 0.82 for predicting complications.
Conclusions
The results of this study suggest that a wider intramedullary diameter and a shorter fixed length at the fracture site are associated with a higher incidence of complications after tibial intramedullary nailing. The RFTI value may be used as a reliable parameter for predicting complications after such surgery. For patients with a high RFTI (≥ 1.31), additional reduction and fixation techniques may be required to obtain and maintain fracture reduction.
Electro-optical properties of strained monolayer boron phosphide: A tight-binding study
Authors: Nobahari Mohammad Mortezaei 
Published: February 2023

Abstract
This paper uses tight-binding approximation and linear response theory to study the electronic and optical properties of strained monolayer boron-phosphide (h-BP). Using previous DFT results, we propose a theoretical tight-binding approach to investigate the strain effects on the electronic and optical properties of the h-BP. Furthermore, we investigate the intra-band and inter-band optical conductivity of pristine and strained h-BP. The isotropic intra-band and inter-band optical conductivity of pristine h-BP are similar to graphene but applying uniaxial strain exerts anisotropic behavior in the system.
Bibliometric Analysis of Publications on Action Recognition; Convolutional Neural Network; Video Surveillance During 2011-2021
Authors: Yalçınkaya Meryem , Akmeşe Ömer Faruk 
Published: February 2023

Abstract
Action recognition based on convolutional neural networks (AR-CNN) has been developing rapidly in recent years. It is of great significance to conduct a deep analysis to understand the recent development of AR-CNN. However, a limited study examining the research status of this field could be found. Therefore, this study aims to quantitatively assess the publications related to the SciVal topic "Action Recognition; Convolutional Neural Network; Video Surveillance (T.561)" in computer vision research. This study focused on six aspects: literature distribution characteristics analysis, the development trend, citation analysis, collaborative analysis, keyword analysis and thematic evolution, using VOSviewer and Bibliometrix. The relevant publications were retrieved from Scopus in the period 2012–2021. A total of 6633 publications were identified by 9088 different authors, 62% were conference papers, and 35% were research articles. China and the USA contributed 39.7 % and 17.9 % of the total publications, respectively. The authors' production according to Price's Law was inconsistent but consistent according to Lotka's Law. Ling Shao was the most productive author, with 48 papers (%0.7). Chinese Academy of Sciences was the most productive affiliation, with 259 papers (%3.9). The first Bradford site consisted of Computer Science Lecture Notes with 617 publications. A moderately significant correlation was revealed between the country's publications and GDP per capita. The overall results show that the number of AR-CNN-related documents has increased significantly in recent years, with rapid growth from 2017. Although publications on AR-CNN were published mainly in European journals, China led the scientific production.
