The accuracy of ultrasound-guided fine-needle aspiration and core needle biopsy in diagnosing axillary lymph nodes in women with breast cancer: a systematic review and meta-analysis

Background This study evaluates the diagnostic accuracy of ultrasound-guided fine needle aspiration (US-FNA) and core needle biopsy (US-CNB) for detecting axillary lymph nodes in women with breast cancer. Methods Eligible studies and pertinent literature resources were identified in Cochrane, PubMed, Embase, CNKI, VIP, and Wanfang databases using subject-specific keywords. Study outcomes were tested for heterogeneity, and meta-analyses were performed to estimate sensitivity, specificity, and diagnostic odds ratios (DORs). The summary receiver operating characteristic (SROC) curve analysis was also performed. Results A total of 22 studies involving 3,548 patients were included to evaluate the diagnostic accuracy of US-FNA and 11 studies involving 758 patients were included to evaluate the diagnostic accuracy of US-CNB in identifying axillary lymph nodes in women with breast cancer. The accuracy of US-FNA in identifying suspicious axillary lymph nodes was as follows: overall sensitivity, 79% (95% CI: 73%–84%); global specificity, 96% (95% CI: 92%–98%); overall positive likelihood ratio, 18.55 (95% CI: 10.53–32.69); overall negative likelihood ratio, 0.22 (95% CI: 0.17–0.28); DOR, 71.68 (95% CI: 37.19–138.12); and the area under the SROC curve, 0.94 (95% CI: 0.92–0.96). The accuracy of US-CNB in identifying suspicious axillary lymph nodes was as follows: overall sensitivity, 85% (95% CI: 81%–89%); global specificity, 93% (95% CI: 87%–96%); overall positive likelihood ratio, 11.88 (95% CI: 6.56–21.50); overall negative likelihood ratio, 0.16 (95% CI: 0.12–0.21); overall DOR, 66.83 (95% CI: 33.28–134.21), and the area under SROC curve 0.96 (95% CI: 0.94–0.97). Conclusions The results indicate that both US-FNA and US-CNB have high accuracy for suspicious axillary lymph nodes.
Non‐invasive sound‐based classifier of bearing faults in electric induction motors

Induction motors play a major role in the industry nowadays due to their simple construc-tion, uncomplicated maintenance, and cost efﬁciency. As the motor operates for repeated hours, some faults may occur and, depending on the process sensitivity, can cause signiﬁcant losses to the industrial production. In this context, an alternative method is proposed to detect and classify bearing faults using acoustic emission signals generated by the machines and simple features obtained from them. A pair of condenser microphones was used to acquire these signals and audio feature extraction is performed to obtain time and frequency patterns to characterize healthy and faulty machines. The major differences of the acoustic signals regarding the fault frequency signatures are discussed by analyzing speciﬁc peaks observed in their spectra. Several coupled load values and levels of power supply voltage unbalance were considered in the experimental tests, which emulate common situations encountered in industrial environments, obtaining accuracy rates over 97% of success. Finally, a comparison is presented of machine learning techniques for bearing faults classiﬁcation under different load values and voltage unbalance levels.
Analysis of the effects of geometry on the press fit application in automotive power modules

Semiconductors and electronics have been found to have an increasing use in automobile design. One key component of an automobile is the power module, which is a high voltage component that finds itself in extreme operating conditions. Due to this condition, the power module demands for highly effective terminal connections that can withstand the extreme operating condition specifically on the terminals that will connect the power module to the automobile system. Press fit technology has been a solution for cheap and reliable methods of creating interconnections since the 1980s; however, necessary innovations exist for more environmental design, and increase demand in quality and quantity. Press fits are simple, force-fitting connectors that allow permanent bonds without solder or adhesive bonding and a shortened process time. This research presents a unique methodology on the evaluation of the effects of the geometry to the insertion force and retention force using finite element analysis. The result showed that the geometry of the pin in a press fit pin configuration has a significant effect on the insertion force, retention force, as well as in the equivalent stress.
Linguistic Barriers in Online Teaching at Undergraduate Level in the University of Malakand Pakistan

Language plays a central role in the teaching-learning process. Without language, teaching can never happen; whether it is face-to-face or online teaching. With the outbreak of covid-19, teaching switched over from face-to-face to online one for the first time. Often, in online teaching linguistic barriers occur, since the teacher is not physically present in the classroom to clarify certain situations. This paper attempts to find out various linguistic barriers that occurred in online teaching at the undergraduate level at the University of Malakand. The researchers selected 380 respondents as participants from the total population through a random purposive sampling technique. Besides, a questionnaire was used for data collection. After the data collection, the results were presented in tabulation form showing the frequency and percentage of the respondents. The results were interpreted and analyzed descriptively. The findings of the study indicated that certain linguistic barriers create problems in online teaching for learners. Among those barriers; usage of the English language, difficult terminologies of teachers, complex sentence structure, unknown jargon for learners, absence of body language, and physical absence of teachers, and strong accents of some teachers are the prominent ones. The study suggests that teachers should be properly trained in online teaching with a special focus on the aforementioned areas of difficulties.
The Response of Juvenile Olive Turtle, Lepidochelys olivacea : The Inclusion of Dried Seaweed and Seagrass in Fish Based-Formulated Feed

A common efforts to improve the survivorship of sea turtle in Indonesia is cage nursery program and fed single food type i.e. fresh fish. Such effort, however, has some constrains such as availability and the sea turtle would tend to be habituated because of single-continuous feeding type. Eventually, it could have impact on to their feeding behaviour and survivorship when it is released to the nature. This study concerns on using easily found dried material suh as fish, sea grass and sea weed. Four feeds type i.e. Fish Pellet (FP); F-Syringodium sp pellet (FSp); Fish-Ulva sp pellet (FUp) and fresh fish (FF)- control, were tested. Completely Randomised Design (CRD) with three replication were applied (totally 9 units + 1 unt for control), four individuals for each experiment unit (totally 40 individuals). The feed are given twice a day (i.e. 8 am and 16 pm). The experiment was run for 8 weeks and sampling of growth response were 2 weeks interval. The results showed that the Fish pellet (FP) resulted in superior response for all criterion ( body weight, length and width of carapace) compared to by fish fresh fish (FF), F-Syringodium sp pellet (FSp) and Fish-Ulva sp pellet (FUp). Daily growth (body weight) were significantly different between diet i.e. 0.71±0.19. g/d, 0.54±0.40 g/d, 0.35±0.77g/d and 0.24±0.30g/d for fish pellet (FP), fresh fish (FF), F-Syringodium sp pellet (FSp) and Fish-Ulva sp pellet (FUp) consecutively (P < 0.05). Nevertheless, the response of carapace length and carapace wide were not significantly different between diets (P > 0.05). The food ratio were FCR > 6 classified low, the efficient feed type (lowest FCR) was shown by fish pllet (FP) feed (i.e. 6.79) and the least efficient (high FCR) was shown by pellet of fish + Ulva sp (FUp) i.e. 24,6. The analysis of body weight – carapace length relationship showed negative allometric (b < 3). The economical analysis on feed production budget indicated that pellet of fish feed (FP) was the highest price, such high cost is due to high price of binder (i.e. CMC). Overall. Overall, the study emphasised that fish pellet feed (FP) was potential feed type to substitute conventional feed i.e. fresh fish for pre released juvenile Olive sea turtle at cage nursery.

Comprehensive Transcriptome and Metabolome Analysis of Lithocarpus polystachyus Leaf Revealed Key Genes in Flavonoid Biosynthesis Pathways

Lithocarpus polystachyus is a unique medicinal tree species that is valued for its abundant flavonoids in leaves. Currently, genes and metabolites involved in the flavonoid biosynthesis pathway remain largely unknown. To elucidate the flavonoid biosynthesis pathways, transcriptome and metabolome analyses of young, mature, and old leaves were conducted. A total of 86,927 unigenes were obtained, and 51.4% of them were annotated in eight public databases. The majority of the 44 candidate genes in the flavonoid biosynthesis pathway were downregulated as leaves aged. Metabolome profiling revealed a set of 427 metabolites in leaves. Consistent with the transcriptome results, 15 of the 19 metabolites in the flavonoid pathway decreased during the development of leaves. The data indicate that young leaf is the optimal stage for tea harvest. This is the first report of integrated transcriptome and metabolome profiling of L. polystachyus. This study demonstrates the correlation of gene expression and metabolites related to flavonoid biosynthesis and reveals the key genes responsible for flavonoid accumulation in young leaf. The information can be applied to future studies performed to elucidate and manipulate flavonoid biosynthesis in L. polystachyus.
Farm income in European agriculture: new perspectives on measurement and implications for policy evaluation

Viable farm households contribute to the resilience of agricultural and food systems. Farm income is a policy-relevant proxy for this viability. Here, we address three key aspects of farm income: first, the income issue, focusing on (average) income levels; second, the variability issue, focusing on income risks faced by farmers; and third, the inequality issue, focusing on the heterogeneity and (in-)equalities of farm incomes. This special issue presents new perspectives on measurement, modelling, development and policies related to the income of farm families in Europe, especially in the light of increasing complexity of farms and policies and risk exposure.
MIKiR’s approach to developing Visual Literacy Skills for PGMI Students at UIN STS Jambi through online lectures

Visual literacy is determined by one’s reading comprehension, visual literacy is always found in our environment, lecturers need to provide opportunities for students to get activities that can develop their visual literacy skills, and it is hoped that these visual skills can be taught to MI / SD students. One of the activities that can support visual literacy is the MIKiR approach. MIKiR stands for Experiencing, Interaction, Communication, and Reflection. Experiencing activities such as students observing, doing experiments, making things. Interaction such as discussing, asking, and answering questions, explaining the results of group work. Communication such as conveying work results, telling stories, expressing opinions. Reflection is like writing or mentioning what was learned today and what was not understood. Online lecture activities carried out with the MIKiR approach are able to develop student visual literacy such as students being able to present messages in text into visual forms and students being able to transform visual messages into written text. The implication of this research is that students are able to develop their visual literacy skills and students are able to choose an appropriate learning approach in improving the visual literacy of students.
Influence of the Internet on Retailer’s Perceived Quality in the Generation of Retailer’s Brand Equity

This study analyses the relationship between the different components of the retailer’s brand equity, as well as the influence that the use of Internet has on the formation of retailer’s brand equity. As some authors point out, there is a need for a measure of the retailer’s brand equity (Boo et al., 2008, Tourism Management, Vol. 30, pp. 219–231; Lee & Back, 2010, Tourism Management, Vol. 31, pp. 395–401). The model proposed to analyse retailer’s brand equity is based on the one used by Boo et al. (2008, Tourism Management, Vol. 30, pp. 219–231), who, in turn, start from the brand equity proposal of the authors Aaker (1991, Managing brand equity: Capitalizing on the value of a brand name, The Free Press) and Keller (1993, Journal of Marketing, Vol. 57, pp. 1–22). A theoretical a priori model was specified according to the results in previous literature and our hypotheses. Prior to testing the model, the dimensionality of the scales was established with confirmatory factor analyses (CFAs). Once the dimensionality was established, full structural equation model (SEM) was tested. This study provides evidence on the effect of the use of Internet on retailer’s perceived quality. In turn, the influence that this variable has on the retailer’s image and on its perceived value is shown. These relationships have an influence on consumer loyalty to the retailer, which, in turn, generates brand equity for the retailer.
Compensating for artifacts in scanning near-field optical microscopy due to electrostatics

Nanotechnology and modern materials science demand reliable local probing techniques on the nanoscopic length scale. Most commonly, scanning probe microscopy methods are applied in numerous variants and shades, for probing the different sample properties. Scattering scanning near-field optical microscopy (s-SNOM), in particular, is sensitive to the local optical response of a sample, by scattering light off an atomic force microscopy (AFM) tip, yielding a wavelength-independent lateral resolution in the order of ∼10 nm. However, local electric potential variations on the sample surface may severely affect the probe–sample interaction, thereby introducing artifacts into both the optical near-field signal and the AFM topography. On the other hand, Kelvin-probe force microscopy (KPFM) is capable of both probing and compensating such local electric potentials by applying a combination of ac and dc-voltages to the AFM tip. Here, we propose to combine s-SNOM with KPFM in order to compensate for undesirable electrostatic interaction, enabling the in situ probing of local electric potentials along with pristine optical responses and topography of sample surfaces. We demonstrate the suitability of this method for different types of materials, namely, metals (Au), semiconductors (Si), dielectrics (SiO2), and ferroelectrics (BaTiO3), by exploring the influence of charges in the systems as well as the capability of KPFM to compensate for the resulting electric force interactions.

Tricuspid atresia type 1B with left superior vena cava in a 4-month-old child: An unusual combination diagnosed by transthoracic echocardiography

Tricuspid atresia (TA) is a rare cyanotic congenital heart disease. A persistent left superior vena cava (LSVC) may be associated with TA. The presence of LSVC raises important considerations for eventual repair, in that it may lead to persistent arterial desaturation even after corrective surgery, if associated with an unroofed coronary sinus. Here, we present the case of a 4-month-old child who was diagnosed with TA type 1B, LSVC and a dilated coronary sinus by transthoracic echocardiography.
Diversity and Seasonality Dynamics of Ciliate Communities in Four Estuaries of Shenzhen, China (South China Sea)

Ciliates are fundamental components of microzooplankton, with important ecological roles. However, ciliate communities are particularly difficult to monitor using conventional morphological approaches. New molecular tools, such as DNA metabarcoding, can facilitate the study of these communities. This study used high-throughput sequencing to examine the diversity and seasonal dynamics of ciliate communities in four estuarine ecosystems in the South China Sea from June 2019 to March 2020. The amplification of the V4 region of 18S rDNA using ciliate-specific primers identified a total of 1645 amplicon sequence variants (ASVs), corresponding to 13 ciliate classes, 97 families, and 157 genera. The dominant species across all four sampling stations were spirotrichs (including choreotrichs, oligotrichs, and stichotrichs), oligohymenophorean scuticociliates, litostomateans Didinium, and prostomateans Cryptocaryon. Significant differences in ciliate diversity and community composition in the four stations were mainly due to differences in rare, rather than abundant, ASVs. Analysis of the ciliate communities and seasonal patterns in their composition revealed that variations in habitat and environmental conditions have a greater effect than seasonal changes on community composition.
Optimal Timing of Introduction of Complementary feeding: Protocol for a systematic review and meta-analysis

Background: The complementary feeding (CF) period accompanies a critical window of vulnerability. During this time, failure to consume adequate energy, protein, vitamins and minerals is a significant concern and can lead to poor growth outcomes, increased susceptibility to infections, allergies, and diseases, and lower developmental potential. It is therefore of utmost importance to determine the most optimal time to start CF. The objective of this review is to assess the impact of early and late of introduction of CF on infant health, nutrition and developmental outcomes.Methods: We will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We will search MEDLINE, Embase, CINAHL, CENTRAL, Web of Science, and other databases and key organizational websites using terms related to complementary feeding and infants. We will also search clinicaltrials.gov for ongoing trials. We will include experimental (randomized trials (individually or cluster) and quasi-randomized trials) and observational studies with a concurrent comparison group (cohort (prospective and retrospective), controlled before-after studies and nested case control studies). We will only include studies that enroll infants, living in low, middle- or high-income countries. Outcomes will be assessed for the following two comparisons:1. Early introduction of CF (before 5 months of age) compared to introduction at 5 to 6.9 months of age2. Late introduction of CF (after 7 months) compared to introduction at 5 to 6.9 months of age All the included studies will be screened on Covidence software and analyzed on Review Manager (version 5.4.1) software.Discussion: There are inconsistencies in the existing recommendations for the introduction of CF, as the recommended age for introducing CF ranges between four and six months of age in various international guidelines. It is imperative to evaluate of consequences of both early and late introduction of complementary foods since optimal timing of introduction may have potential beneficial short- and long-term health effects.

Tandem Heterojunction Photoelectric Cell Based on Organic-Inorganic Hybrid of AlPc-H2Pc and n-Si

The tandem heterojunction photoelectric cell has been fabricated on the basis of organic-inorganic hybrid of AlPc-H2Pc (aluminium phthalocyanine-metal free phthalocyanine) and n-Si using pressing technique along with vapor deposition. Initially, the AlPc-H2Pc heterojunction films of thickness 150 nm were deposited on the ITO coated glass and the n-Si substrates as well by vapor deposition. Both the substrates (ITO glass and n-Si) were pressed and fixed together by keeping the deposited heterojunction films face to face. The pressing was done at elevated temperature (60-80 degrees C), while fixing was carried out by using adhesive. A 100 nm thick silver (Ag) film was deposited on the back of n-Si substrate. The complete architecture of the device was as ITO/AlPc:H2Pc/n-Si/Ag. The AFM and UV-visible spectroscopy were used to investigate the morphology and optical properties of the organic (AlPc-H2Pc) films, respectively. The cell was characterized for current-voltage behavior in dark and also under illumination. The values of I-SC, V-oc, fill factor (FF) and efficiency under illumination of 290 W/m(2) were equal to 0.7 V, 2.17 mA/cm(2), 0.33 and 1.1%, respectively.
Current mode control of single phase grid tie inverter with anti-islanding

The aim of this paper is to explore the use of various current mode control (CMC) techniques to design a single phase grid tie inverter integrated with anti-islanding protection. Three types of CMC techniques have been discussed, namely current hysteresis control (CHC), constant frequency control (CFC) and average current mode control (ACMC). The performance of the grid tie inverter in the event of grid voltage failure is also studied to help install an anti-islanding mechanism. The proposed control techniques shall eliminate the use of Phase locked loop (PLL) control as the current reference is generated from the grid voltage itself. All three current mode control techniques of an inverter have been simulated in MATLAB/Simulink to evaluate the performance of the designed inverter. The simulated results show a current THD of less than 5% in all three methods and a good anti-islanding response.
