Evaluation of the Accuracy of the Sound Field Separation Method under Variations in the Location of the Sampling Points
Authors: Lopez Mejia Sebastian , Piedrahita Montes Andres Felipe 
Published: April 2022

Context: Measuring the directivity characteristics and the frequency response of acoustic sources is a difficult process, as the dimensions and boundary conditions of the testing rooms used could constrain the measurement procedure. The testing room should guarantee a free-field condition, which is usually satisfied by using big acoustic absorbers with fibrous materials with high absorption coefficients. However, standing wave patterns can be easily developed due to the frequency range exciting the testing room.
Method: The sound field separation method can isolate the radiated field of an acoustic source by sampling the sound field around it over two holographic spheres. The coordinates of the sampling points are used in a set of equations, whose solution can estimate the radiated field. In this paper, the effect of the variability on the actual positions of these sampling points is investigated.
Results: Two numerical simulations with and without external sources outside the holographic spheres were performed. In all simulations, variations in the radial position of the sampling points were induced, and the relative reconstruction error, the directivity index, and the frequency response were studied. The results indicate that, for the estimation of the directivity of low-frequency acoustic sources, regardless of the presence of external sources, radial positioning of the sensors does not have to be exact to obtain an accurate reconstruction.
Conclusions: This study suggests that, in the experimental characterization in conventional testing rooms of the radiated field from acoustic sources whose main frequency region corresponds to low frequencies, e.g. subwoofers, the SFS method could be used, thus obtaining high accuracy in the estimation of the directivity of the source.
H-atom and O-atom methods: from balancing redox reactions to determining the number of transferred electrons
Authors: Yuen Pong Kau , Lau Cheng Man Diana 
Published: April 2022

AbstractDefining and balancing redox reaction requires both chemical knowledge and mathematical skills. The prevalent approach is to use the concept of oxidation number to determine the number of transferred electrons. However, the task of calculating oxidation numbers is often challenging. In this article, the H-atom method and O-atom method are developed for balancing redox equations. These two methods are based on the definition of redox reaction, which is the gain and loss of hydrogen or oxygen atoms. They complement current practices and provide an alternate path to balance redox equations. The advantage of these methods is that calculation of oxidation number is not required. Atoms are balanced instead. By following standard operating procedures, H-atom, O-atom, and H2O molecule act as artificial devices to balance both inorganic and organic equations in molecular forms. By using the H-atom and O-atom methods, the number of transferred electrons can be determined by the number of transferred H-atoms or O-atoms, which are demonstrated as electron-counting concepts for balancing redox reactions. In addition, the relationships among the number of transferred H-atom, the number of transferred O-atom, the number of transferred electrons, and the change of oxidation numbers are established.

Authors: Al-Dikheeli Mohammed Riyadh , Thaib Hasanein M. , Alasadi Layth AbdulRasool 
Published: April 2022

Abstract
This work intends to make structural lightweight aggregate concrete by using artificial expanded clay aggregate with different replacement levels from normal coarse aggregate and improve it with a high-performance superplasticizer to increase its strength. The mechanical characteristics covered in the present work were compressive strength, flexural strength, and splitting tensile strength in addition to freezing and thawing resistance. Different densities were found for all mixes ranging between normal and lightweight concrete and that depends on the replacement of normal aggregate with lightweight aggregates. Mixes with replacement exceeding 25% give compressive strength less than 17 MPa and cannot be regarded as structural lightweight concrete. Modified mixes give higher values of mechanical properties, and also some non-structural lightweight concrete mixes were improved to structural lightweight concrete by using PC-superplasticizer in this study. The research also includes freezing and thawing cycles on reference mixes and lightweight mixes. Lightweight mixes give high durability against freeze-thaw cycles where the reduction in compressive strength was 6.2, 4.6, and 5.5% for 10% rep, 15% rep, and 20% rep mixes, respectively, compared with 32.2% reduction for reference mix.
Self-efficacy beliefs among baccalaureate nursing students – A cross-sectional, comparative study
Authors: Nordhus Gerd E.M. , NaNongkhai Pancheewa , Hofseth Almås Synnøve 
Published: April 2022

Abstract
The aim of this study is to explore baccalaureate nursing students’ self-efficacy beliefs related to theoretical coursework. Self-efficacy, i.e., the perception of one’s ability to successfully complete a task, has been shown to correlate positively with academic performance and persistence. Nursing students from a large Norwegian university participated (n=132). Data were collected through a digital questionnaire and analyzed using SPSS statistics. Descriptive analysis was performed. Student groups were compared according to gender, age, and year of study using one-way analyses of variance and independent sample t-tests. The findings suggest that the students’ self-efficacy beliefs related to theoretical coursework are quite high, with few significant differences between the groups. While the students have confidence in their ability to reach academic goals, self-efficacy when facing stress and distraction is lower. The findings may be of interest to educators striving to optimize learning in baccalaureate nursing programs.
The association between induction of labour in nulliparous women at term and subsequent spontaneous preterm birth: a retrospective cohort study
Authors: Ho Nicole , Liu Cathy Z. , Tanaka Keisuke , Lehner Christoph , Sekar Renuka , Amoako Akwasi A. 
Published: April 2022

Abstract

Objectives
To evaluate the rate of subsequent spontaneous preterm birth in patients with previous induction of labour at term compared to women with previous spontaneous labour at term.

Methods
This was a retrospective cohort study of all women with consecutive births at the Royal Brisbane and Women’s Hospital between 2014 and 2018. All nulliparous women with a singleton pregnancy and induction of labour at term or in spontaneous labour at term in the index pregnancy were included. Data was extracted from electronic medical records. The outcome of spontaneous preterm birth in the subsequent pregnancy was compared between patients with previous term induction of labour and in previous term spontaneous labour.

Results
A total of 907 patients with consecutive births met the inclusion criteria; of which 269 (29.7%) had a term induction of labour and 638 (70.3%) had a term spontaneous labour in the index pregnancy. The overall subsequent spontaneous preterm birth rate was 2.3%. Nulliparous women who underwent term induction of labour were less likely to have a subsequent preterm birth compared to nulliparous women in term spontaneous labour (0.74 vs. 2.98%; odds ratio [OR], 0.25; 95% confidence interval, 0.06–1.07; p=0.0496) in the index pregnancy. This however was not significant once adjusted for confounders (adjusted OR, 0.29; p=0.10). Spontaneous preterm birth was associated with a previous spontaneous labour compared to induction of labour between 37 to 37+6 and 38 to 38+6 weeks (adjusted OR 0.18 and 0.21; p=0.02 and 0.004 respectively).

Conclusions
Term induction of labour does not increase the risk of subsequent spontaneous preterm birth compared to spontaneous labour at term in nulliparous women. Further research is needed to validate these findings in a larger cohort of women and to evaluate the effect of elective IOL among low-risk nulliparous women.

Published: April 2022

Abstract
Innate immune receptors detect nucleic acids, such as viruses, and initiate an immune response by secreting interferon (IFN) and regulating IFN-stimulated genes (ISG). in autoimmune conditions, expression of ISGs funded, show the activation of nucleic acid sensory pathways. However, the nucleus-localized innate sensors are recently found to detect pathogenic nucleic acids for initiating innate response, demonstrating a complicated crosstalk with cytoplasmic sensors and signaling molecules to form an elaborate tiered innate signaling network between nucleus and cytoplasm. to sustain immune hemostasis, these innate immune sensors develop different strategies for discriminating between self or non-self-nucleic acid. We reviewed all the sensors involved in the innate immune system in the present study. A better understanding of these sensors can lead to new treatments for infections, cancer, and autoimmune and inflammatory disorders.
Research on facial expression recognition based on an improved fusion algorithm
Authors: Yaermaimaiti Yilihamu , Kari Tusongjiang , Zhuang Guohang 
Published: April 2022

AbstractThis article puts forward a facial expression recognition (FER) algorithm based on multi-feature fusion and convolutional neural network (CNN) to solve the problem that FER is susceptible to interference factors such as non-uniform illumination, thereby reducing the recognition rate of facial expressions. It starts by extracting the multi-layer representation information (asymmetric region local binary pattern [AR-LBP]) of facial expression images and cascading them to minimize the loss of facial expression texture information. In addition, an improved algorithm called divided local directional pattern (DLDP) is used to extract the original facial expression image features, which not only retains the original texture information but also reduces the time consumption. With a weighted fusion of the features extracted from the above two facial expressions, new AR-LBP-DLDP facial local features are then obtained. Later, CNN is used to extract global features of facial expressions, and the local features of AR-LBP-DLDP obtained by weighted fusion are cascaded and fused with the global features extracted by the CNN, thereby producing the final facial expression features. Ultimately, the final facial expression features are input into Softmax for training and classification. The results show that the proposed algorithm, with good robustness and real-time performance, effectively improves the recognition rate of facial expressions.

Abstract
Ultraviolet rays – B (UVB) can be efficiently absorbed by the cellular molecules of skin inducing damage within skin cells and a major cause of melanoma cancer. In recent years, several studies have reported the adverse effects of traditionally used organic and inorganic material-based sunscreens and UVB blockers. In this study, bovine serum albumin (BSA) has been used as a precursor to synthesize temperature- and pressure-dependent phase transition from sol (globular aggregates) – gel (hydrogels) – sol (carbon quantum dots) using a single-step hydrothermal method with an objective to develop an efficient and effective UVB blocker. The synthesized hydrogels exhibit UV – attenuation, self-fluorescence, and high biocompatibility properties that make them a suitable candidate for UV-blocker or sunscreen material. The biological efficacy of the hydrogels was studied through cyto-toxicity studies. Also, UVB blocking efficiency of developed hydrogel in primary mice skin cell culture as well as in vivo in mice model was studied. In vivo study on mice further demonstrated prominent thickening of stratum corneum and epidermis with perivascular edema in the dermis after 5 days of UVB exposure. Hence, this suggesting that hydrogel could be a potential candidate for protecting the skin from UVB exposure and reducing the threat of skin cancer.

Abstract
Indonesian chili faces some problems in increasing production, added value, and competitiveness of chili products, mainly in terms of quantity, quality, and continuity. The objectives of this study are (1) to analyze the private and social profitability of chili farming, (2) to analyze the chili competitiveness from both competitive and comparative advantage perspectives, (3) to examine government policy impact on chili performance, and (4) to formulate strategies to encourage chili development in Indonesia. The results of the policy analysis matrix revealed that chili farming in Indonesia’s production centers is profitable, both privately and socially. It also has competitiveness, both competitive and comparative advantages. The highest competitiveness occurs in Bandung district, West Java, with a coefficient of private cost ratio (PCR) of 0.416 and a domestic resource cost ratio (DRCR) of 0.269. Meanwhile, the lowest competitiveness occurs in Tabalong district, South Kalimantan, with a PCR coefficient of 0.857 and a DRCR of 0.556. This study also concluded that for Indonesia, it is more profitable to increase domestic chili production than importing from abroad. Strategic policies for chili development can be implemented by using hybrid seeds, complete and balanced fertilization, improving irrigation infrastructure and farming roads, increasing the capacity of farmers’ resources, and expanding the objectives and market segments.
Mesolithic Montology
Authors: Warren Graeme 
Published: April 2022

Abstract
This article focuses on the Mesolithic occupation of mountain environments in Europe. The montane Mesolithic is a important aspect of the Mesolithic as a whole, but neither its significance nor its potential is fully recognised. Evidence also suggests that we have not communicated this to the wider interdisciplinary community of mountain researchers – a field sometimes known as montology – which is dominated by models of human behaviour in mountains drawn from agricultural examples. Leading publications in the latter field have suggested that human use of mountains can be understood as structured by three key themes: resources, valuable minerals and precious stones, and the cultural importance of mountains. These themes are used to review the Mesolithic record.
Improving the usefulness of research data with better paradata
Authors: Huvila Isto 
Published: April 2022

Abstract
Considerable investments have been made in Europe and worldwide for developing research data infrastructures. Instead of a general lack of data about data, it has become apparent that a pivotal factor that drastically constrains data use is the absence of contextual knowledge about how data was created and how it has been curated and used. This applies especially to many branches of social science and humanities research, where data is highly heterogeneous, both by its kind (e.g. being qualitative, quantitative, naturalistic, purposefully created) and origins (e.g. being historical/contemporary, from different contexts and geographical places). The problem is that there may be enough metadata (data about data) but there is too little paradata (data on the processes of its creation, curation and use). The aim of this position paper is to draw attention 1) to the need for a better and more systematic understanding and documentation of the contexts of creation, curation and use of research data to make it useful and usable for researchers and other potential users in the future, and 2) to specific obstacles that make the capturing of this particular type of metadata, known as paradata, especially difficult. Failing to understand what information about the creation, curation and use of research data is needed and how to capture enough of that information risks that the currently collected vast amounts of research data become useless in the future.

Published: April 2022

Abstract
Group–subgroup schemes are a useful tool in crystal chemistry for systemizing crystal structures and they are an indispensable help during X-ray crystallographic studies of complex, twinned and modulated structures. Meanwhile many superstructure variants are summarized within so-called Bärnighausen trees. The present database lists relevant literature with respect to the crystallographic/group-theoretical tools and original work and gives a tabulated overview on the crystallographic fingerprints (aristotype, space group symbol, Pearson code and Wyckoff sequence) of the respective superstructures.
Anterior Cingulate Cortex Signals the Need to Control Intrusive Thoughts during Motivated Forgetting
Authors: Crespo-García Maité , Wang Yulin , Jiang Mojun , Anderson Michael C. , Lei Xu 
Published: April 2022

How do people limit awareness of unwanted memories? When such memories intrude, a control process engages the right DLPFC (rDLPFC) to inhibit hippocampal activity and stop retrieval. It remains unknown how the need for control is detected, and whether control operates proactively to prevent unwelcome memories from being retrieved, or responds reactively, to counteract intrusions. We hypothesized that dorsal ACC (dACC) detects the emergence of an unwanted trace in awareness and transmits the need for inhibitory control to rDLPFC. During a memory suppression task, we measured in humans (both sexes) trial-by-trial variations in the theta power and N2 amplitude of dACC, two EEG markers that are thought to reflect the need for control. With simultaneous EEG-fMRI recordings, we tracked interactions among dACC, rDLPFC, and hippocampus during suppression. We found a clear role of dACC in detecting the need for memory control and upregulating prefrontal inhibition. Importantly, we identified distinct early (300–450 ms) and late (500–700 ms) dACC contributions, suggesting both proactive control before recollection and reactive control in response to intrusions. Stronger early activity was associated with reduced hippocampal activity and diminished BOLD signal in dACC and rDLPFC, suggesting that preempting retrieval reduced overall control demands. In the later window, dACC activity was larger, and effective connectivity analyses revealed robust communication from dACC to rDLPFC and from rDLPFC to hippocampus, which are tied to successful forgetting. Together, our findings support a model in which dACC detects the emergence of unwanted content, triggering top-down inhibitory control, and in which rDLPFC countermands intruding thoughts that penetrate awareness.SIGNIFICANCE STATEMENTPreventing unwanted memories from coming to mind is an adaptive ability of humans. This ability relies on inhibitory control processes in the prefrontal cortex to modulate hippocampal retrieval processes. How and when reminders to unwelcome memories come to trigger prefrontal control mechanisms remains unknown. Here we acquired neuroimaging data with both high spatial and temporal resolution as participants suppressed specific memories. We found that the anterior cingulate cortex detects the need for memory control, responding both proactively to early warning signals about unwelcome content and reactively to intrusive thoughts themselves. When unwanted traces emerge in awareness, anterior cingulate communicates with prefrontal cortex and triggers top-down inhibitory control over the hippocampus through specific neural oscillatory networks.

Published: April 2022

ÖZ
Rejeneratif endodontik tedavi başarılı tedavi sonuçları sayesinde son yıllarda popülerlik kazanmıştır. Bu tedavinin immatür dişlerde semptomların ortadan kaldırılması, durmuş olan kök gelişiminin devamı ve dişlerin canlılık kazanması gibi hedefleri vardır. İmmatür dişlerde rejeneratif endodontik tedavi sonrası kök gelişiminin devam ettiği birçok çalışmada gösterilmiştir. Fakat tedavi sonrası kök oluşum şekilleri değişkenlik göstermektedir. Chen ve ark. tarafından bu tedaviden sonra görülen 5 farklı tip kök yanıtı gösterilmiştir. Bunlar köklerin uzayıp kapanması, köklerin künt kapanması, kök apeksinin açık kalması, kanal obliterasyonu, kanal içerisinde sert doku bariyeri oluşmasıdır. Fakat bu kök yanıtlarından farklı olarak kök apeksinin ana kökten ayrılarak gelişimini devam ettirdiği nadir görülen farklı bir kök yanıt tipi bildirilmiştir. Bu çalışmada da rejeneratif endodontiden sonra nadir görülen ayrık kök gelişiminin teşhisi, tedavisi ve takibi anlatılmıştır.

ABSTRACT
Regenerative endodontic treatment has gained popularity in recent years thanks to successful treatment results. This treatment has goals such as eliminating symptoms in immature teeth, continuation of the stopped root development and vitality of teeth. It has been shown in many studies that root development continues after regenerative endodontic treatment in immature teeth. Five different types of root response seen after this treatment were demonstrated by Chen et al. These are elongation and closure of the roots, blunt closure of the roots, open root apex, canal obliteration, formation of a hard tissue barrier. However, unlike these root responses, a different type of root response, which is rarely seen, has been shown to continue its development by separating the root apex from the main root. In this study, the diagnosis, treatment and follow-up of split root development, which is rare after regenerative endodontics, is explained.
