A New Platform of Iron Oxide-Based Nanoparticles Assay Using GMR Chip-Based Sensor With Microcontroller

The low-cost, simple, and fast quantitative assay of magnetic nanoparticles (MNPs) is important for the development of magnetic-based immunoassay applications. However, the bulky sensing element and instruments of the recent iron oxide-based MNPs assays are still concerns that should be resolved. This article reports the new platform of an iron oxide-based MNPs label assay using the commercial giant magnetoresistance (GMR) chip AAL024, manufactured by Nonvolatile Electronics (NVE) Corporation, complemented with a basic differential amplifier circuit and Arduino microcontroller (AM) to acquire the digital output voltage. The as-prepared Fe3O4@Ag label possessed (15 ± 2.6) nm of average size and behaved as soft ferromagnetic with 52.1 emu/g of saturation magnetization, and 0.15 kOe of coercive field. Sensor performance for magnetic field detection, as well as Fe3O4@Ag nanoparticles label assay, was evaluated. The results show the implementation of a basic differential amplifier op-amp circuit succeed to magnify the sensor’s response to the magnetic field up to 23 times with the output voltage in the order of volt. The employment of the AM as a voltage supply of the GMR chip, an analog-to-digital converter, and a voltage gauge simplifies the data acquisition without the additional measuring instrument. Meanwhile, for the purpose of the Fe3O4@Ag nanoparticles label assay, the sensor revealed promising performance due to the high signal linearity and the rapid detection which is only 30 s with acceptable signal stabilities.
Analysis of 2013 Curriculum Implementation in Elementary Schools

This study aims to obtain an overview of implementation, analyze and formulate problem-solving strategies in implementing the 2013 curriculum at SD Negeri Padang City. This study uses a qualitative method, with a phenomenological approach. The results of the study show that the implementation of the 2013 curriculum mostly refers to Permendikbud No. 81A 2013 regarding the implementation of the 2013 curriculum. Then the results of the analysis show that the curriculum does not contain the unique content of the education unit which is the hallmark of the curriculum at SD Negeri Gunung Pangilun, Padang City. The 2013 curriculum is still limited, learning support facilities such as LCD, laptop, wireless, additional library books and air conditioning are still limited, infrastructure facilities such as science laboratory buildings, language fields and sports are not yet available. In addition, the problem-solving strategy used requires the design of an in-house training program to increase the understanding of teachers and parents regarding the implementation of the 2013 curriculum. LCD, laptop, wireless, additional library books and air conditioning, require infrastructure support in the form of procurement of science laboratory buildings, language laboratories and sports fields.
Survey on Blockchain-Based IoT Payment and Marketplaces

The ever-growing smart applications will expand the Internet of Things (IoT) ecosystem to connect over 75 billion devices by 2025. IoT ecosystems comprise sensors that act as data suppliers and applications where monetary transactions are required to compensate the data producers. This signifies the importance of IoT payments and marketplaces to facilitate micro-transactions of billions of connected devices in the IoT ecosystem, which is heterogeneous, decentralized, and diverse. However, realizing such an ecosystem raises multiple challenges such as overcoming poor inter-operability, resource constraints, and security and privacy vulnerabilities of IoT devices and platforms. Blockchain is a Distributed Ledger Technology (DLT) that can be identified as a potential solution to overcome the challenges in realizing IoT payments and marketplaces. This is due to the characteristics of blockchain such as decentralization, traceability, immutability, and non-repudiation. This paper presents a comprehensive survey on blockchain-based IoT payments and marketplaces. This paper provides a brief introduction to the concepts of IoT payments and IoT marketplaces. Then the technical challenges involved in realizing IoT payment and marketplaces are discussed by highlighting the blockchain-based solutions. Furthermore, blockchain-based smart applications which use IoT marketplace and IoT payment concepts are presented marking the role of blockchain in each of the application. Subsequently, the paper discuss the integration challenges while also highlighting possible solutions. It is envisaged that this paper would shed light on the development of blockchain-based solutions to realize IoT payments and marketplaces.
Research of sine waveguide slow-wave structure for a 220-GHz backward wave oscillator

A watt-class backward wave oscillator is proposed, using the concise sine waveguide slow-wave structure combined with a pencil electron beam to operate at 220 GHz. Firstly, the dispersion curve of the sine waveguide is calculated, then, the oscillation frequency and operating voltage of the device are predicted and the circuit transmission loss is calculated. Finally, the particle-in-cell simulation method is used to forecast its radiation performance. The results show that this novel backward wave oscillator can produce over 1-W continuous wave power output in a frequency range from 210 GHz to 230 GHz. Therefore, it will be considered as a very promising high-power millimeter-wave to terahertz-wave radiation source.
Efficient Soft Switching Single-Stage PFC for Low-Power Applications

Single-stage (SS) power factor correction (PFC) converters are applied as the power supply for low-power devices. Usually, the flyback converter is merged with the PFC stage to eliminate the reset winding required for the transformer. This article merges a new resonant forward converter with the buck-boost PFC stage. Thus, reset winding of the forward converter is eliminated while soft switching is achieved. Due to the low flux of the forward transformer core, transformer volume is reduced. Also, for the same volume of the transformer, transformer losses can be reduced in comparison to the flyback converter. The proposed converter is analyzed, and design considerations are discussed. A prototype converter is implemented. According to the experimental results, high efficiency and low total harmonic distortion (THD) are achieved.
Time-Constrained Service Handoff for Mobile Edge Computing in 5G

Many mobile device applications require low end-to-end latency to edge computing infrastructure when offloading their computation tasks in order to achieve real-time perception and cognition for users. User mobility brings significant challenges in providing low-latency offloading due to the limited coverage area of cloudlets. Virtual machine (VM)/container handoff is a promising solution to seamlessly transfer services from one cloudlet to another to maintain low latency as users move. However, an inefficient path planning for the handoff can result in system congestion and consequently poor Quality of Service (QoS). The situation can even worsen by selfish users who intentionally lie about their true parameters to achieve better service at the cost of degrading the whole system's performance. To fill this research gap, we propose an Online Service Handoff Mechanism (OSHM) to provide an efficient path dynamically for transferring VM/container from the current serving cloudlet to a nearby cloudlet at the destination of a mobile user. Our proposed path planning algorithm is based on a label correction methodology, leading to polynomial time complexity. OSHM is accompanied by our proposed payment determination function to discourage misreporting of unknown parameters. We discuss the theoretical properties of our proposed mechanism in implementing a system equilibrium and ensuring truthfulness. We also perform a comprehensive assessment through extensive experiments which show the efficiency of OSHM in terms of workload, handoff time, consumed energy, and other metrics compared to several benchmarks. Experimental results show that OSHM outperforms other algorithms, reducing at least 61% in average workload, 33% in average handoff time, and 29% in average energy consumption.
A Soft-Sensing Model for Predicting Cement-Specific Surface Area Based on Inception-Residual-Quasi-Recurrent Neural Networks

The cement-specific surface area is a critical indicator of cement quality. Most of the relevant detection instruments are now used for offline detection, which has high cost and poor real-time performance. For this reason, a soft-sensing model can be developed to achieve the purpose of predicting the quality of cement. However, due to the data features in the process of cement grinding is complexity and coupling, the prediction accuracy of the universal model is not high and can not achieve good prediction results. Based on the above problems, an inception-residual-quasi-recurrent neural networks (R-QRNNs)-based cement-specific surface area prediction model is proposed in this article. The model uses the inception module’s parallel structure to extract a wider variety of data characteristics and enhance the reuse rate of critical features, successfully avoiding poor network prediction caused by discrepancies in convolutional kernel selection in superimposed convolutional layers. In the meantime, distinct convolutional modules use independent spatial aggregation kernels from different channels to improve spatial aggregation and reduce data coupling. Then, the traditional quasi-recurrent neural network (QRNN) convolutional layers at the previous moment output $c_{t-1} $ of the hidden layer and the input $x_{t} $ are replaced by the residual modules. By integrating the inception and residual modules with QRNN, a novel inception-R-QRNN neural network is constructed. Overfitting is effectively avoided, and generalization ability is improved. The validity of the model is verified by experiments.
Resveratrol Supplementation in Obese Pregnant Rats Improves Maternal Metabolism and Prevents Increased Placental Oxidative Stress

Maternal obesity (MO) causes maternal and fetal oxidative stress (OS) and metabolic dysfunction. We investigated whether supplementing obese mothers with resveratrol improves maternal metabolic alterations and reduces OS in the placenta and maternal and fetal liver. From weaning through pregnancy female Wistar rats ate chow (C) or a high-fat diet (MO). One month before mating until 19 days’ gestation (dG), half the rats received 20 mg resveratrol/kg/d orally (Cres and MOres). At 19dG, maternal body weight, retroperitoneal fat adipocyte size, metabolic parameters, and OS biomarkers in the placenta and liver were determined. MO mothers showed higher body weight, triglycerides and leptin serum concentrations, insulin resistance (IR), decreased small and increased large adipocytes, liver fat accumulation, and hepatic upregulation of genes related to IR and inflammatory processes. Placenta, maternal and fetal liver OS biomarkers were augmented in MO. MOres mothers showed more small and fewer large adipocytes, lower triglycerides serum concentrations, IR and liver fat accumulation, downregulation of genes related to IR and inflammatory processes, and lowered OS in mothers, placentas, and female fetal liver. Maternal resveratrol supplementation in obese rats improves maternal metabolism and reduces placental and liver OS of mothers and fetuses in a sex-dependent manner.
Groundwater Responses to Earth Tides: Evaluation of Analytical Solutions Using Numerical Simulation

Harmonic Earth tide components in well water levels have been used to estimate hydraulic and geomechanical subsurface properties. However, the robustness of various methods based on analytical solutions has not been established. First, we review the theory and examine the latest analytical solution used to relate well water levels to Earth tides. Second, we develop and verify a novel numerical model coupling hydraulics and geomechanics to Earth tide strains. Third, we assess subsurface conditions over depth for a range of realistic properties. Fourth, we simulate the well water level response to Earth tide strains within a 2D poroelastic layered aquifer system confined by a 100 m thick aquitard. We find that the non‐linear inversion of analytical solutions to match two observations (amplitudes and phases) to multiple unknown parameters is sensible to the initial guess. We reveal that undrained, confined conditions are necessary for the analytical solution to be valid. This occurs for the dominant M2 frequency at depths >50 m and requires specific storage at constant strain of Sϵ ≥ 10−6 m−1, hydraulic conductivity of the aquitard of kl ≤ 5 ⋅ 10−5 ms−1 and aquifer of ka ≥ 10−4 ms−1. We further illustrate that the analytical solution is valid in unconsolidated systems, whereas consolidated systems require additional consideration of the Biot modulus. Overall, a priori knowledge of the subsurface system supports interpretation of the groundwater response. Our results improve understanding of the effect of Earth tides on groundwater systems and its interpretation for subsurface properties.
Sixteen logic functions in a single electronic circuit

This paper introduces an electronic circuit capable of generating a set of functions, some of them known in digital systems as the logical operators AND, OR, XOR, and so on. Using two inputs, u1 and u2 , the circuit provides 16 possible output combinations. The main idea of the electronic design is based on an RC network, operational amplifiers, and voltage comparators. On the other hand, mathematically, the stable system response is used as a surface where u1 and u2 are coordinate axes forming a plane, which intersects this surface, and the output y can be seen as a circle surrounding some fixed points over this plane. The mathematical approach on this paper is intended as a groundwork for a multiple input reconfigurable logic gate that could be embedded in more complex systems. The procedure to obtain an XOR gate, represented by the f(6) function, is explained to illustrate the circuit behavior. Results of the 16 implemented functions are shown in Appendices B and C.
Quantum bohr compactification of discrete quantum groups

We introduce the analog of Bohr compactification for discrete quantum groups on C*-algebra level. The cases of unimodular and general C*-algebraic discrete quantum groups are treated separately. The passage from the former case to the latter is done with help of the concept of canonical Kac quotient for compact quantum groups\footnotemark. Several examples are presented and passage to the Bohr compactification is investigated.
An effective points of interest recommendation approach based on embedded meta‐path of spatiotemporal data

With the development of mobile networks and the rapid prevalence of location‐based social networks (LBSN), a massive volume of spatiotemporal data has been generated, which is valuable for points of interest (POI) recommendation. However, current studies have not unleashed the full power of such spatiotemporal data, which either explore only a single dimension of the data or consider multiple factors in an asynchronous fashion. In this article, we propose a novel spatiotemporal network‐based recommender framework (STNBR) to effectively recommend POIs for users. Specifically, we first establish a comprehensive conceptual model of spatiotemporal data, involving various essential factors for POIs recommendation. On top of the conceptual model, we design a series of meaningful meta‐paths that simultaneously consider the time and location factors to precisely capture the semantics of user behaviours. By profiling users based on their embedded meta‐paths, our approach can yield meaningful POIs recommendations. We have evaluated our proposal using a realistic dataset obtained from Foursquare and Gowalla, the results of which show that our STNBR model outperforms existing approaches.
Effect of processing method and severity for hybrid fall rye on dry matter intake, ruminal fermentation, and apparent total tract nutrient digestibility in ruminally cannulated beef heifers

Abstract This study compared dry-rolled and tempered hybrid rye when processed to a coarse or fine severity on dry matter intake (DMI), ruminal fermentation, and apparent total tract nutrient digestibility for beef cattle. Eight ruminally cannulated Simmental heifers (327 ± 33.1 kg, mean ± SD) were used in a replicated 4 × 4 Latin square (21-day periods with 16 days for adaptation and 5 d collection) balanced for carry-over effects with a 2 × 2 factorial arrangement of treatments. Feeding tempered rye increased (P = 0.01) DMI when compared to dry-rolled rye, but there was no effect of processing severity. Cattle fed dry-rolled rye had a greater (P = 0.04) area that pH was <5.5 when compared to those fed tempered rye. Feeding dry-rolled rye increased dry matter digestibility (P = 0.02) and crude protein digestibility (P = 0.01) when compared to tempered rye, and there was a greater effect to increase total tract starch digestibility with increasing severity of processing for tempering than for dry rolling (interaction, P = 0.03). In conclusion, tempered hybrid rye processed to a fine severity may result in similar total tract starch digestibility to dry-rolled hybrid rye without the marked reductions in DMI and ruminal pH. Cette étude a comparé un hybride de seigle aplati à sec et conditionné, lorsque transformé selon une sévérité brute ou fine, et les effets sur la consommation des matières sèches (DMI — «dry matter intake»), la fermentation dans le rumen, et la digestibilité apparente du tractus total des éléments nutritifs auprès des bovins de boucherie. Huit génisses Simmental canulées dans le rumen (327 ± 33,1 kg, moyenne ± écart type [SD — «standard deviation»]) ont été utilisées dans un carré latin 4 × 4 répliqué (périodes de 21 jours avec 16 jours pour adaptation et 5 jours de collecte) équilibré pour les effets de report avec un arrangement factoriel 2 × 2 des traitements. L’alimentation au seigle conditionné a augmenté (P = 0,01) le DMI par rapport au seigle aplati à sec, mais il n’y avait pas d’effet de la sévérité de transformation. Les bovins ayant reçu le seigle aplati à sec avaient une plus grande (P = 0,04) surface dont le pH était inférieur à 5,5 par rapport au seigle conditionné. Nourrir les bovins de seigle aplati à sec a augmenté la digestibilité des matières sèches (P = 0,02) et la digestibilité des protéines brutes (P = 0,01) par rapport au seigle conditionné, et il y avait un plus grand effet d’augmentation de la digestibilité de l’amidon dans le tractus total avec l’augmentation de la sévérité de transformation pour le seigle conditionné par rapport au seigle aplati à sec (interaction, P = 0,03). En conclusion, le seigle hybride conditionné transformé à sévérité fine peut se traduire par une digestibilité de l’amidon dans le tractus total semblable à celle du seigle hybride aplati à sec sans les réductions marquées de DMI et de pH dans le rumen.

The Lonely Life of a Champion Tree, Aesculus glabra

Seedlings derived from two Ohio buckeyes (Aesculus glabra Willd.) trees, the National Champion growing in Illinois, USA, and the Ohio State Champion were sampled. The National Champion grows at the northern limits of the species’ native range. The Ohio State Champion grows in Huron County, Ohio, well within the eastern range of the species. We also sampled 40 adult trees growing in Ohio and Illinois. All trees were genotyped at six microsatellite loci. We found that 42 of the 44 sampled seedlings (95%) from the National Champion tree, collected over two seasons, exhibited only maternal alleles at all six microsatellite loci, indicating they were produced by self-fertilization. In contrast, all seedlings from the Ohio state champion tree (N = 48) exhibited non-maternal alleles, indicating they were produced by outcrossing. Our results suggest that when outcross pollen is not available, A. glabra will self-fertilize, but does so rarely or never when outcross pollen is available. Seed germination and early survival were similar for progeny of both champions, but seedlings from the National Champion show lower growth rates and higher mortality during a spring frost, possibly due to inbreeding depression. There was little evidence for genetic structure between trees sampled in Ohio and Illinois.
The Effectiveness of Pharmacopuncture in Patients with Lumbar Spinal Stenosis: A Protocol for a Multi-Centered, Pragmatic, Randomized, Controlled, Parallel Group Study

Purpose Lumbar spinal stenosis (LSS) is a chronic degenerative disease. Non-surgical intervention is recommended, considering the risks and benefits for the affected age group, as well as the characteristics of the disease. However, to date, no studies have compared various non-surgical interventions to ascertain the appropriate first-line non-surgical treatment for LSS. Therefore, the objective of this study will be to assess the efficacy of pharmacopuncture as a non-surgical, conservative treatment for LSS. Patients and Methods A multi-centered, pragmatic, parallel-group study will be conducted. In total, 98 patients will be recruited at seven institutes; recruitment began in May 2022. After two treatment sessions per week over a period of 12 weeks, follow-up assessments will be held at weeks 13, 25, and 53. Results The efficacy of pharmacopuncture and conservative care will be pragmatically compared in patients radiologically diagnosed with LSS. Pain severity will be measured using the numeric rating scale and visual analog scale. Walking distance will also be evaluated. Patient-centered evaluations will include the Zurich Claudication Questionnaire, Short-Form 12 for Health-Related Quality of Life, EuroQoL 5 Dimension 5 Levels, and Patient Global Impression of Change. Conclusion The results of this study will confirm the efficacy of pharmacopuncture in comparison to conventional non-surgical treatment and will thus facilitate the prioritization of patient-centered interventions for LSS. Trial registration This study was registered at Clinicaltrials.gov (registration identifier: NCT05242497) and CRiS (registration identifier: KCT0007145).
Prediction of high-speed rotor noise with a Kirchhoff formula

Abstract : A new methodology has been developed to predict the impulsive noise generated by a transonic rotor blade. The formulation uses a full potential finite-difference method to obtain the pressure field close to the blade. A Kirchhoff integral formulation is then used to extend these finite-difference results in o the far field. This Kirchhoff formula is written in a blade fixed coordinate system. It requires initial data across a plane at the sonic radius. This data is provided by the finite difference solution. Acoustic pressure predictions show excellent agreement with hover experimental data for two hover cases of 0.88 and 0.90 tip Mach number. The latter of which has delocalized transonic flow. These results represent the first successful prediction technique for peak pressure amplitudes using a computational code.
Diversity and inclusion in advertising research

Abstract Diversity in advertising research refers to the portrayal of people with distinct attributes in advertising, while inclusion refers to the valuation of their presence and perspectives in advertising. The most commonly investigated diversity attributes in advertising research are gender, ethnicity, sexual orientation, and age. Extant research indicates a mis- and underrepresentation of certain groups in society but shows that diverse and inclusive advertising can have favorable brand and social effects. Future research should include other diversity attributes (e.g., disabilities, gender identity, and religion), consider multiple diversity attributes and intersectionality, and include an advertiser perspective to understand why advertising sometimes is neither diverse nor inclusive.
