Numerical Study of Lateral Migration of Elliptical Magnetic Microparticles in Microchannels in Uniform Magnetic Fields

This work reports numerical investigation of lateral migration of a paramagnetic microparticle of an elliptic shape in a plane Poiseuille flow of a Newtonian fluid under a uniform magnetic field by direct numerical simulation (DNS). A finite element method (FEM) based on the arbitrary Lagrangian–Eulerian (ALE) approach is used to study the effects of strength and direction of the magnetic field, particle–wall separation distance and particle shape on the lateral migration. The particle is shown to exhibit negligible lateral migration in the absence of a magnetic field. When the magnetic field is applied, the particle migrates laterally. The migration direction depends on the direction of the external magnetic field, which controls the symmetry property of the particle rotational velocity. The magnitude of net lateral migration velocity over a π cycle is increased with the magnetic field strength when the particle is able to execute complete rotations, expect for α = 45° and 135°. By investigating a wide range of parameters, our direct numerical simulations yield a comprehensive understanding of the particle migration mechanism. Based on the numerical data, an empirical scaling relationship is proposed to relate the lateral migration distance to the asymmetry of the rotational velocity and lateral oscillation amplitude. The scaling relationship provides useful guidelines on design of devices to manipulate nonspherical micro-particles, which have important applications in lab-on-a-chip technology, biology and biomedical engineering.
Preliminary Evidence for Heterogeneity of Beliefs About Auditory Verbal Hallucinations Intent

Supplemental digital content is available. Abstract Perceptions of patient's auditory verbal hallucinations (AVHs), commonly termed voices, have important impacts on their everyday lives. Despite research emphasizing the consequences of malevolent voices, preliminary results suggest that beliefs about voices may not be mutually exclusive. As such, we aimed to characterize the heterogeneity of beliefs about AVHs and describe their clinical correlates. We recruited 78 patients referred to a Voices group therapy for refractory and distressing voices. Based on the Revised Beliefs About Voices Questionnaire, clustering analysis yielded four subgroups of patients with distinct pattern of beliefs about AVHs. These subgroups differed significantly in terms of affective disturbances, engagement, and resistance to their voices. Furthermore, no significant changes in beliefs about voices were observed after 6 weeks. Results of the current study suggest that the heterogeneity regarding the beliefs about AVHs should be targeted in treatment to reduce their associated negative outcomes.
The Effect of Nutritional Education with Leaflet and Diet Application on Nutritional Status Changes in Obese College Students

Obesity is excessive body fat condition due to differences in energy consumption and expenditure. In Indonesia, the prevalence of obese women >18 years old is 32.9%. Interventions are performed with control eating and increased physical activity through an educational approach. A Leaflet is a print media containing some information, while my weight loss diet application is used by people that want to lose weight. Therefore, this study aims to determine the effect of nutritional education with leaflet and my weight loss diet application on nutritional status changes in obesity. True experimental design was used with pre-post test on female students divided into two groups in Universitas Brawijaya (n= 44) and selected by purposive sampling. Also, Independent-Samples T-Test and Mann Whitney analysis were conducted. The results showed a body mass index decrease in both media and no significant change related to BMI (p = 0.733). However, the decrease was more shown on the leaflet, where the body fat percentage had a significant change (p = 0.000). Hence, intervention using the leaflet is more effective on nutritional status changes related with BMI and body fat percentage in obese students.
Acute and Short-term Results of MitraClip XTR vs. PASCAL Transcatheter Valve Repair System for Edge-to-Edge Repair of Severe Tricuspid Regurgitation

ABSTRACT Background Novel device developments enable the edge-to-edge treatment of inoperable patients with severe tricuspid regurgitation (TR) and large coaptation gaps. We compared the acute and short-term results of patients treated with the MitraClip XTR vs. PASCAL system. Methods We retrospectively analyzed 120 patients (72 pts. MitraClip XTR, 48 pts. PASCAL) treated for isolated severe TR on a compassionate-use basis. Results Mean patient age was 77 ± 8 years and the LaPar risk score was 6.7 ± 1.7%. Patients in the PASCAL group had a larger coaptation gap and a trend to more severe TR. Procedural success (TR ≤ 2) was achieved in 92% of patients in each group (XTR group: 66/72, PASCAL group: 44/48). Thirty-day follow-up was available in 94% of patients. Two patients in the PASCAL group and one patient in the MitraClip XTR group died within 30-days of the procedure. Device complications were observed in 15.3% of patients in the XTR group and in 10.4% of patients in the PASCAL group. There was a trend for a more pronounced reduction of vena contracta width in the PASCAL group compared to the XTR group. Tricuspid repair was associated with a comparable improvement in New York Heart Association (NYHA) functional class and 6-minute walking distance in both groups. Conclusion The PASCAL and the MitraClip XTR system appeared to be highly efficacious in treating patients with severe TR with a comparable rate of device complications in both groups but a trend for a more pronounced reduction of vena contracta width in the PASCAL group.

Commercial Limits to Personality: Instagram Influencers and Commoditized Content Receptivity

Social media influencers-individuals who utilize various forms of network power on social networks occupy a unique identity space. On the one hand, their network power is often tied to their social identity as creators of engaging material. On the other hand, their ability to promote commercial products and services steps outside the traditionally distinct commercial–social, occupational–personal divides. In this work, the network morphologies of influencers are explored in relation to their delivery of sponsored and non-sponsored content. This article explores how the disclosure of content as ‘sponsored’ affects audience reception. We show how that the promotion of content on social media often generates higher levels of engagement and receptiveness amongst their audience despite the platform’s assumption of organic non-commercial relationships. We find that engagement levels are highest among smaller out-degree networks. Additionally, we demonstrate that sponsored content not only returns a higher level of engagement, but that the effect of sponsorship is relatively consistent across out-degree network sizes. In sum, we suggest that social media audiences are not sensitive to commercial sponsorship when tied to identity, as long as that performance is convincing and consistent.
Impact of Nutrient Additions on Free‐Living Nitrogen Fixation in Litter and Soil of Two French‐Guianese Lowland Tropical Forests

In tropical forests, free‐living Biological nitrogen (N) fixation (BNF) in soil and litter tends to decrease when substrate N concentrations increase, whereas increasing phosphorus (P) and molybdenum (Mo) soil and litter concentrations have been shown to stimulate free‐living BNF rates. Yet, very few studies explored the effects of adding N, P, and Mo together in a single large‐scale fertilization experiment, which would teach us which of these elements constrain or limit BNF activities. At two distinct forest sites in French Guiana, we performed a 3‐year in situ nutrient addition study to explore the effects of N, P, and Mo additions on leaf litter and soil BNF. Additionally, we conducted a short‐term laboratory study with the same nutrient addition treatments (+N, +N+P, +P, +Mo, and +P+Mo). We found that N additions alone suppressed litter free‐living BNF in the field, but not in the short‐term laboratory study, while litter free‐living BNF remained unchanged in response to N+P additions. Additionally, we found that P and P+Mo additions stimulated BNF in leaf litter, both in the field and in the lab, while Mo alone yielded no changes. Soil BNF increased with P and P+Mo additions in only one of the field sites, while in the other site soil BNF increased with Mo and P+Mo additions. We concluded that increased substrate N concentrations suppress BNF. Moreover, both P and Mo have the potential to limit free‐living BNF in these tropical forests, but the balance between P versus Mo limitation is determined by site‐specific characteristics of nutrient supply and demand.
A Bypassable Scan Flip-Flop for Low Power Testing With Data Retention Capability

The power consumption of modern highly complex chips during scan test is significantly higher than the power consumed during functional mode. This leads to substantial heat dissipation, excessive IR drop, and unrealistic timing failures of the integrated circuits (ICs) under test. In this brief, a ByPassable Scan Data Retention Flip-Flop (BPS-DRFF) is proposed for low-power IC test. The proposed flip-flop contains two secondary latches. The output of the “function” secondary latch goes to the following combinational circuits, while the other “shadow” secondary latch is used to shift test vectors during scan test. By gating the output of the function secondary latch, the redundant switching activity in the combinational circuits is eliminated during scan shift, thereby reducing the test power consumption significantly. The suppressed switching activity also leads to lower IR drop across the chip, increasing the chip manufacturing yield. Furthermore, the shadow latch is reused for data retention in the sleep mode while performing power gating, thereby alleviating the area cost of the shadow latch. The proposed BPS-DRFF also eases the hold time sign-off in the test mode due to the elongated clock-to-Q contamination delay that is brought in by the shadow latch. The proposed design is applied to an AES-128 crypto core in a UMC 55-nm low power CMOS technology. Experiment results show that 68.5% power is saved during scan test with the proposed BPS-DRFF, compared to the standard scan retention flip-flop.
Application of Artificial Intelligence in Basketball Sport

Basketball is among the most popular sports in the world, and its related industries have also produced huge economic benefits. In recent years, the application of artificial intelligence (AI) technology in basketball has attracted a large amount of attention. We conducted a comprehensive review of the application research of AI in basketball through literature retrieval. Current research focuses on the AI analysis of basketball team and player performance, prediction of competition results, analysis and prediction of shooting, AI coaching system, intelligent training machine and arena, and sports injury prevention. Most studies have shown that AI technology can improve the training level of basketball players, help coaches formulate suitable game strategies, prevent sports injuries, and improve the enjoyment of games. At the same time, it is also found that the number and level of published papers are relatively limited. We believe that the application of AI in basketball is still in its infancy. We call on relevant industries to increase their research investment in this area, and promote the improvement of the level of basketball, making the game increasingly exciting as its worldwide popularity continues to increase.
Smart Detection of Faults in Beers Using Near-Infrared Spectroscopy, a Low-Cost Electronic Nose and Artificial Intelligence

Early detection of beer faults is an important assessment in the brewing process to secure a high-quality product and consumer acceptability. This study proposed an integrated AI system for smart detection of beer faults based on the comparison of near-infrared spectroscopy (NIR) and a newly developed electronic nose (e-nose) using machine learning modelling. For these purposes, a commercial larger beer was used as a base prototype, which was spiked with 18 common beer faults plus the control aroma. The 19 aroma profiles were used as targets for classification ma-chine learning (ML) modelling. Six different ML models were developed; Model 1 (M1) and M2 were developed using the NIR absorbance values (100 inputs from 1596–2396 nm) and e-nose (nine sensor readings) as inputs, respectively, to classify the samples into control, low and high concentration of faults. Model 3 (M3) and M4 were based on NIR and M5 and M6 based on the e-nose readings as inputs with 19 aroma profiles as targets for all models. A customized code tested 17 artificial neural network (ANN) algorithms automatically testing performance and neu-ron trimming. Results showed that the Bayesian regularization algorithm was the most adequate for classification rendering precisions of M1 = 95.6%, M2 = 95.3%, M3 = 98.9%, M4 = 98.3%, M5 = 96.8%, and M6 = 96.2% without statistical signs of under- or overfitting. The proposed system can be added to robotic pourers and the brewing process at low cost, which can benefit craft and larger brewing companies.
Investigating the Impact of Critical Factors on Continuous Usage Intention towards Enterprise Social Networks: An Integrated Model of IS Success and TTF

Due to the outbreak of COVID-19, many people have to accept remote working. However, as COVID-19 has been effectively controlled in China, remote office services provided by enterprise social networks (ESNs) is no longer a necessary choice of users. There has not yet been any referential research for ESN enterprises concerning how to encourage users willing to use ESNs continuously. Therefore, the purpose of this research is to identify the critical factors of ESN continuous usage intention to make up the research gap of ESN continuous usage intention and to help enterprises address the issue of sustained growth. This research combines elements of the task technology fit (TTF) model and D&M information systems success (ISS) model, explaining the continuous usage intention of ESN users. The empirical analysis results are based on the sample data of 668 Chinese respondents with experience in ESNs use and analyzed using structural equation modeling (SEM). Results show that task technology fit, performance expectancy and the satisfaction degree have a significant influence on continuous usage intention of ESNs. The research findings can provide the theoretical basis for sustained development and follow-up research of the ESN industry.
A mixed culture performing nitrite-dependent anaerobic methane oxidation and the nitrite removal mechanism revealed by high-throughput sequencing

Nitrite-dependent anaerobic methane oxidation (n-DAMO) has been regarded as a promising effective approach to nitrogen removal from wastewater. However, n-DAMO bacteria are very difficult to be enriched in biological wastewater treatment processes. An anaerobic sequencing batch reactor (AnSBR) was introduced in the present study for the enrichment of n-DAMO bacteria with cornfield soil as inoculum. Fed with nitrite (NO2−) and methane as the specific substrates, a NO2− load removal as high as 46.16 mg/(L·d) was obtained in the AnSBR since the 232nd day of enrichment culturing, though the relative abundance of Candidatus Methylomirabilis referring to n-DAMO bacteria was 2.37% in the acclimatized mixed culture. High-throughput sequencing of the obtained mixed culture revealed that the community structure was complex with the coexistence of n-DAMO bacteria, methanotrophs, heterotrophic denitrifying bacteria and hydrolytic fermentation bacteria. Analysis of interactions among the prevalent microbial populations suggested that Candidatus Methylomirabilis had played a key role in the metabolic network of the mixed culture. The research work presented a novel approach to the enrichment of n-DAMO bacteria from cornfield soil and was helpful in understanding the role of n-DAMO bacteria in complex matrices.
Titanium Periimplant Tissue Alterations: A Prospective Cohort Plate Retrieval Study

Commercially pure titanium and titanium alloys have been extensively used in materials to reconstruct the facial skeleton in different forms and sizes. There is yet to be a consensus on removing (or not) the plates and screws after osteosynthesis. Our study tries to investigate the adjacent tissues of the titanium plates used in jaw surgery using inductively coupled plasma optical emission spectrometry. Twenty samples of soft tissue surrounding the titanium plates were retrieved 1 year after placement (fracture sites or orthognathic surgery) and were investigated using inductively coupled plasma optical emission spectrometry. The study found 1.06 ppm titanium in the adjacent soft tissues. Even if there are no clinical signs of the presence of titanium in the soft tissues, our findings suggest that a plate removal is a feasible option for patients to avoid local complications due to titanium migration.
Informal employment or informal firms? Regulatory enforcement and the transformation of the informal sector

While there is general agreement that regulatory avoidance is an important part of firms' decisions to produce in the informal sector, there is much less agreement on how regulation and enforcement affect firms' decisions on, inter alia, which sector they locate in, their employment decisions, and whether to transition from one sector to another. In this paper, we focus on this set of questions: how does the regulatory regime affect these sectoral location decisions by firms?
Active nickel hollow nanosphere supported over SiO2 catalyst for reduction of nitro compound

Abstract Nickel hollow nanospheres (Ni HNSs) was prepared by solvothermal method using mixture of ethylenediamine (EN) and ethanol (ET), sodium borohydride as reducing agent and nickel chloride hexahydrate as precursor. The particle size of the Ni HNSs were tuned by varying several parameters including precursor concentrations, reaction temperatures (130–190 °C), and ET to EN volume ratios. The particle size and morphology of Ni HNSs were confirmed by dynamic light scattering and transmission electron microscope, respectively. Spherical shape of Ni nanoparticles of 300 nm size having ∼200 nm hollow space and 50 nm thickness was achieved at optimize condition of 4:6 volume ratio of ET/EN, 150 °C temperature, 0.1 M NaBH4 concentration, and 7 h. Ni HNSs supported over SiO2 (Ni HNSs/SiO2) with different loading of Ni HNSs (1–10 wt.%) were prepared by impregnation method. The catalyst was characterized by X-ray diffraction, and inductively coupled plasma - optical emission spectroscopy. The catalytic performance of Ni HNSs/SiO2 was carried out in the reduction of 4-Nitrophenol (4-NP) to 4 – Aminophenol (4-AP). 5 wt. % Ni HNSs/SiO2 exhibited 87% reduction of 4-NP in 25 min and stable up to 6 catalyst cycles due to higher surface area of the catalyst.
MCEMP1 as a Tumor Microenvironment and Immune Infiltration Related Gene for Prognostic Prediction in Advanced Gastric Cancer

Background Tumor microenvironment (TME) has displayed profound clinical significance in cancer progression, prognosis and the efficacy of immunotherapy. However, the overall characteristics of TME in patients with advanced gastric cancer (AGC) have not been intensively studied. In order to get a more comprehensive understanding, this study aimed to investigate TME-related prognostic genes in patients with AGC based on bioinformatics, combined with histological verification.Methods Transcriptome and clinical data on stage III/IV GC were obtained from The Cancer Genome Atlas (TCGA) database. The data of stromal, immune scores and 22 infiltrating immune cells from AGC samples were evaluated by ESTIMATE and CIBERSORT algorithms. Then, mast cell-expressed membrane protein 1 (MCEMP1) was focused by integrated protein-protein interaction (PPI) network and Cox regression. The survival and expression analysis of MCEMP1 was evaluated and verified in tissues by immunohistochemistry (IHC) and quantitative real-time PCR (qRT-PCR). Results There was a positive correlation between TME scores and pathological grades. A total of 666 TME-related differential genes were screened. MCEMP1 was identified as a predictive factor related to the prognosis of AGC both in TCGA database and tissue samples. Further analysis indicated that MCEMP1 was involved in regulating pathways of immune activities. The results of CIBERSORT demonstrated that MCEMP1 expression was significantly correlated with the proportion of 8 kinds of infiltrating immune cells. Conclusion As a TME-related prognostic gene, MCEMP1 might play a crucial role in remodeling immune infiltrates in AGC patients, which might be a potential immunotherapy target for patients with AGC.
GIBBERELLIC ACID PRIMING ENHANCES MAIZE SEED GERMINATION UNDER LOW WATER POTENTIAL

Germination is a portentous yield determining factor that is a challenge in the low water potential environment due to disrupted imbibition. Hormonal seed priming can markedly increase the germination on maize even in such a stressful environment. Therefore, research was aimed to analyze the application of gibberellic acid (GA3) priming to maize seeds to minimize the deleterious effects of reduced water potential. GA3 priming was done at 0, 50, 100, 150, and 200 ppm for 12 hours and subjected to drought levels of 0, 0.15, 0.50, 1.05, and 1.75 MPa by using NaCl solution. Different germination parameters, i.e., germination percentage, mean germination time, germination index, relative water content, seedling vigor index, root length, and shoot length, were determined on the final day of the experiment. The results showed that all germination parameters were adversely influenced by low water potential. Every level of GA3 priming has hastened all parameters. GA3 priming at 100 ppm decreased the mean germination time by 35 hours under 1.75 MPa compared to non-primed seeds. GA3 priming increased the shoot length of maize seedlings with a shoot length of 2.9 cm in non-primed seedlings compared to 6.4 cm in 200 ppm GA3 priming under 1.05 MPa. GA3 priming is the best method for the early establishment of maize seedlings in low water potential conditions. As a result, it may be utilized as a low-cost and straightforward approach for establishing maize crops under saline and drought conditions.
