Male Layer Chicken’s Response to Dietary Moringa oleifera Meal in a Tropical Climate

Simple Summary In the egg industry, most slow-growing chicks are usually euthanized at 1-day-old even though it has been demonstrated that they are well-suited to production systems with outdoor access. However, the rearing of these birds, as an option to address the ethical concerns related to their disposal at such an early age, is impaired by high feeding costs. Therefore, it is crucial to evaluate non-conventional feeding materials that could be incorporated into their diets. Moringa is a non-traditional feed for poultry; nevertheless, studies investigating slow-growing breeds’ performance when fed Moringa while given access to outdoors in the tropics are limited. Thus, the current study evaluated slow-growing chickens’ response to dietary Moringa in terms of production performance, carcass yield, and blood parameters. The results revealed that all cumulative traits were not negatively affected by the treatments (except for feed conversion). Additionally, both breast weight and yield and gizzard weight and yield significantly increased with dietary Moringa, while blood parameters remained unaltered. It is concluded that Moringa, as a feed ingredient, could be added to the diets of slow-growing male chickens grown with outdoor access in the tropics to improve productive and carcass traits, but feed conversion could be increased. Abstract This study was conducted to evaluate the effects of different dietary amounts of Moringa oleifera meal (MOM), consisting of leaves and small edible green stems, on growth performance, carcass traits, and blood parameters of finisher male layer-type slow-growing chickens raised with outdoor access. A total of 198 Dominant Blue D 107, 72-day-old male chickens were randomly assigned to tree dietary treatments containing 0, 30, and 60 g/kg MOM that corresponded to T1 or control, T2, and T3, separately. Each treatment was divided into 6 replicates of 11 birds apiece, and all birds had access to the outdoors. After 7 weeks of experimental rearing, live weight was 2218.1, 2164.4, and 2176.6 g for birds raised in T1, T2 and T3, respectively, without statistical differences (p ≥ 0.05). Live weight gain and daily live weight gain increased (p ≤ 0.05) in favor of the control group during the first 4 weeks but decreased (p ≤ 0.05) in the last 3 weeks of the trial. Overall feed intake was not influenced by the treatments (p ≥ 0.05). Birds raised with MOM in their diets had higher feed conversion (p ≤ 0.05). T2 diet considerably increased (p ≤ 0.05) birds’ breast and gizzard weight and yield while decreasing feet weight and yield, in comparison to T1. Dietary MOM inclusion did not impair or improve (p ≥ 0.05) blood parameters. The results of this study suggest that up to 60 g/kg MOM could be included in the diets of slow-growing Dominant Blue D 107 male chickens grown with access to outdoors without compromising their productive performance (except for feed conversion), slaughter characteristics, and health status.
A Singular-Feed Circularly Polarized Metasurface Antennas Using Characteristic Mode Analysis

– In this paper, a singular-feed circularly polarized (CP) metasurface antenna with broad impedance bandwidth is presented. The antenna consists of modified slots with a lattice of 3 × 3 square conductive patches. Modes are selected and excited by modified slot by using characteristic mode analysis. Wideband characteristics are achieved thanks to the modified slots, leading to a new resonance. The circular polarization characteristics are generated by exciting via single feeding simultaneously. The positions of feeding are determined via characteristic mode analysis. Compared with conventional methods, the presented analysis can simplify the feeding structure and provided a compact antenna. The simulated results show an impedance bandwidth of 82% and 3 dB AR at 2.4 GHz Wireless Local Area Network (WLAN) bands.

Effect of transcranial direct current stimulation combined with a smart hand joint training device on hand dysfunction in patients with early stroke.

INTRODUCTION The aim of this study was to investigate the effect of transcranial direct current stimulation (tDCS) combined with a smart hand joint training device on hand dysfunction in patients with early stroke. MATERIAL AND METHODS This study was a randomized controlled trial, which was conducted in the neurology department in our hospital. From March 2019 to January 2021, 60 patients diagnosed with early stroke hand dysfunction were selected. A random number table method was used to divide patients equally into control group (smart hand joint training device group) and intervention group (tDCS and smart hand joint training device group). Before and after treatment, Brunnstrom six-level staging, Fugl-Meyer motor function score (wrist hand part), hemiplegic finger function examination, and hemiplegic hand function classification evaluation were applied in both groups. Main outcome measures were Brunnstrom motor function staging (hand part), functional evaluation of hemiplegic fingers, and Fugl-Meyer motor function score (wrist hand part). RESULTS After treatment, compared with control group, the results in intervention group of Brunnstrom six-level staging and hemiplegic hand function classification evaluation showed obvious improvement (p = 0.000), and the result of hemiplegic fingers' functional evaluation also improved (p = 0.026). After treatment, Fugl-Meyer motor function scores were 6.73 ±6.65 (control group) and 9.8 ±6.66 (intervention group). Slight tDCS-related adverse events occurred in one patient (3.33%) in intervention group. None in either group discontinued treatment. CONCLUSIONS Both the smart hand joint training device alone and tDCS combined with the smart hand joint training device can improve hand function of patients with early stroke to varying degrees, but the treatment effect of tDCS combined with the smart hand joint training device is more significant.
Novel PID Tracking Controller for 2DOF Robotic Manipulator System Based on Artificial Bee Colony Algorithm

Abstract This study presents a well-developed optimization methodology based on the dynamic inertia weight Artificial Bee Colony algorithm (ABC) to design an optimal PID controller for a robotic arm manipulator. The dynamical analysis of robotic arm manipulators investigates a coupling relation between the joint torques applied by the actuators and the position and acceleration of the robot arm. An optimal PID control law is obtained from the proposed (ABC) algorithm and applied to the robotic system. The designed controller optimizes the trajectory of the robot’s end effector for a time-variant input and makes the robot robust in the presence of external disturbance.

Anticancer activity in “60 lines screening” (NCI DTP protocol) was studied in vitro for the title compound.
Synthesis and characterization of waste Styrofoam hypercrosslinked polymer as an adsorbent for CO2 capture

In this work, we used waste Styrofoam as a precursor to synthesize a hypercrosslinked polymeric (HCP) adsorbent for CO2 adsorption utilizing the Friedel–Craft procedure. The hypercrosslinked adsorbent was designed using formaldehyde dimethyl acetal (FDA) as the crosslinker. The precursor to crosslinker to catalyst ratio was 1:3:3, and the HCP synthesis was carried out for 12 h at 312.6 K. Fourier‐transform infrared spectroscopy, field emission scanning electron microscopy, and thermogravimetric analysis were used to analyze the waste Styrofoam hypercrosslinked (WSHC) adsorbent. The adsorbent attained an 802.84 m2/g Brunauer–Emmett–Teller (BET) surface area and an average pore diameter of 2.869 m3/g. The CO2 adsorption process was studied under different operating conditions, temperature between 298 and 328 K and pressure between 2 and 10 bar. WSHC adsorbent has the maximum CO2 uptake with a value of 11.053 mmol/g at 298 K and 10 bar. The behavior of the adsorption process was investigated using isotherm, kinetic, and thermodynamic models. Experimental findings indicated that the Sips isotherm and the second‐order kinetic models provided the best fit. The isotherm data indicated that adsorption occurs in multi‐layers and is heterogeneous. According to the thermodynamic characteristics, the process is exothermic and spontaneous. Finally, the kinetic findings established that the process happened physically. Additionally, a regeneration study after seven cycles revealed a 96.1% success rate. The current research may attempt to use waste Styrofoam as a gas separation adsorbent in the industry.
Millimeter-Wave Harmonically-Tuned Silicon Power Amplifiers for High Efficiency

This research utilizes the Class F harmonic tuning approach to improve the power efficiency and power added efficiency (PAE) of the silicon power amplifiers (PAs) at mm-wave frequency bands. This work tunes the 2 and 3 harmonic componets of voltage and current waveform over active device to improve the efficiency of the PA. The potentials and limitations of the class-F technique in achieving a high PAE at microwave and higher frequencies, especially for integrated PAs based on silicon process have been analyzed. To demonstrate effectiveness of the Class-F approach a multi-resonance 6 order load network is proposed which achieves 50% power added efficiency with 18dBm output power at 24GHz. By optimizing this network for 38GHz, based on the loss of passive components, PAE of 38.5% achieved. The design methodology developed for this network and extensive small signal, large signal, and linearity performance of both PAs presented. To further improve power efficiency of Class F PAs, coupled inductor based harmonic tuning load network proposed. The load network, utilizes coupled inductors to enhance quality factor of the inductors and make wide bandwidth high impedance at 2 harmonic and very low impedance at 3 harmonic, which improves both efficiency and efficiency bandwidth. By using this load network and optimizing for 28GHz, 2-stage PA implemented with PAE~42% with 16.5dBm output power. As frequency increases to >30 GHz, the complexity of load network degrades the power efficiency improvement of the Class-F PAs. A simple /4 transformer based load network proposed to tackle this issue and achieve high power efficiency. Using this load network, PAs implemented with exceptional PAE performance of 43% at 41 GHz and 23% 94 GHz with output power of 18 dBm and 11 dBm, respectively. To increase peak PAE bandwidth of PA, a simple LC-based multi-resonance network proposed which provides in band mode transition from Continuous-Class-F to Continuous-Class-F. The PA operated at Continuous-Class-F mode at low signal frequency band and Continuous-Class-F mode at high signal frequency band. By using mode-transition, PAE > 36.5% achieved over 25% fractional bandwidth (25 GHz~31 GHz). In summary, this research presents different harmonic tuning load networks for Class F operation to address different issues and improve efficiency of mm-wave silicon PAs.

It can play an excellent role in sports events and postgame video analysis, and provide a good basis and certain design ideas for the goal tracking of the sports industry.
Experimental Evaluation of Roaming Performance of Cellular IoT Networks

As the growth of the Internet of Things (IoT) devices continues, more and more wireless technologies are getting introduced into the market. NarrowBand-IoT and Long-Term Evaluation Cat M1 (LTE-M) are two Low-Powered Wide Area Network (LPWAN) communication technologies introduced by 3GPP in release 13 of LTE. Some of the features supported by these Cellular-IoT (C-IoT) technologies include low power consumption, extended coverage, low cost of deployment, roaming between Mobile Network Operator’s (MNO) networks, etc. This paper focuses on the experimental evaluation of NB-IoT and LTE-M networks in an international roaming scenario. The goal behind the experiments is to test and benchmark the performance of NB-IoT and LTE-M by calculating network Key Performance Indicators (KPIs) such as bitrate, end-to-end latency, and packet drop in a home and in roaming network scenarios. In order to perform the experiments, a Danish operator is chosen with nationwide coverage in Denmark (DK), Sweden (SE), and Norway (NO). A total of 6000 packets with varying payload sizes are sent using both the C-IoT technologies in all three countries combined. The idea behind the experiments is to test whether or not C-IoT technologies are reliable for supporting roaming applications in the IoT paradigm.
Recommending Crowdfunding Project: A Graph Kernel-Based Link Prediction Method for Extremely Sparse Implicit Feedback

It is a critical task to provide recommendation on implicit feedback, and one of the biggest challenges is extreme data sparsity. To tackle the problem, a graph kernel-based link prediction method is proposed in this paper for recommending crowdfunding projects combining graph computing with collaborative filtering. First of all, an investor-project bipartite graph is established based on transaction histories. Then, a random walk graph kernel is constructed and computed, and a one-class SVM classifier is built for link prediction based on implicit feedback. At last, top N recommendations are made according to the ranking of investor-project pairs. Comparative experiments are conducted and the results show that the proposed method achieves the best performance on extremely sparse implicit feedback and outperforms baselines. This paper is of help to improve the success rate of crowdfunding by personalized recommendation and is of significance to enrich the research in recommendation systems.
Detangling ecosystem services: Open‐field manipulation of soil‐dwelling microarthropods provides new opportunities to investigate their effects on nitrogen cycling

Abstract Soil microarthropods have a pivotal role in soil nitrogen cycling in that they affect microbial decomposers. A high abundance of microarthropods may increase the mobility of inorganic nitrogen ions in the soil, mainly in nitrogen‐limited habitats. However, it is difficult to study ecological processes with small‐sized, soil‐dwelling arthropods. The effects of soil microarthropods on nitrogen cycling have mainly been studied in laboratory microcosm experiments. Therefore, we face many practical issues in investigating these effects under field conditions that remain to be resolved. We developed an open‐field mesocosm setup with growing plants. In a two‐part experiment, spring wheat and grass species were grown in chernozem and sandy soils. Leached ammonium and nitrate ions were measured with percolation lysimeters. Half of the mesocosms included natural assemblages, and the other half included less abundant Acari and Collembola assemblages. The application of nitrogen fertilization assured differences in nitrogen sources. We found a large difference in ammonium and nitrate leaching between the two soil types. In chernozem soil, the leached ion concentrations were higher in mesocosms with more abundant mite and springtail assemblages. The expected patterns were less pronounced in sandy soil. Adding nitrogen fertilizer did not modify the effects of soil microarthropods. Open‐field mesocosms are promising for studying the role of soil‐dwelling mesofauna in ecological processes. We solved the problem of keeping mesofauna abundance lower in treated plots than that in control plots. Plants successfully grew in our semi‐closed systems with functioning percolation lysimeters. The use of the equipment in the experiments in this study helped reveal that the role of soil‐dwelling microarthropods in nitrogen cycling depends on the soil type and not on the application of nitrogen fertilizer.
Clinical and Biological Adaptations in Obese Older Adults Following 12-Weeks of High-Intensity Interval Training or Moderate-Intensity Continuous Training

Sarcopenia and obesity are considered a double health burden. Therefore, the implementation of effective strategies is needed to improve the quality of life of older obese individuals. The aim of this study was to compare the impact of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on functional capacities, muscle function, body composition and blood biomarkers in obese older adults. Adipose tissue gene expression and markers of muscle mitochondrial content and quality control involved in exercise adaptations were also investigated. Sixty-eight participants performed either HIIT (n = 34) on an elliptical trainer or MICT (n = 34) on a treadmill, three times per week for 12 weeks. HIIT produced significantly higher benefits on some physical parameters (six-minute walking test (HIIT: +12.4% vs. MICT: +5.2%); step test (HIIT: +17.02% vs. MICT: +5.9%); ten-repetition chair test (HIIT: −17.04% vs. MICT: −4.7%)). Although both HIIT and MICT led to an improvement in lower limb power (HIIT: +25.2% vs. MICT: +20.4%), only MICT led to higher improvement in lower limb muscle strength (HIIT: +4.3% vs. MICT: +23.2%). HIIT was more beneficial for increasing total lean body mass (HIIT: +1.58% vs. MICT: −0.81%), while MICT was more effective for decreasing relative gynoid fat mass (HIIT: −1.09% vs. MICT: −4.20%). Regarding adipose tissue gene expression, a significant change was observed for cell death-inducing DFFA (DNA fragmentation factor-alpha)-like effector A (CIDEA) in the HIIT group (A.U; HIIT at T0: 32.10 ± 39.37 vs. HIIT at T12: 48.2 ± 59.2). Mitochondrial transcription factor A (TFAM) content, a marker of mitochondrial biogenesis, increased significantly following HIIT (+36.2%) and MICT (+57.2%). A significant increase was observed in the HIIT group for Translocase of Outer Membrane 20 (TOM20; +54.1%; marker of mitochondrial content), Mitofusin-2 (MFN2; +71.6%; marker of mitochondrial fusion) and Parkin RBR E3 Ubiquitin Protein Ligase (PARKIN; +42.3%; marker of mitophagy). Overall, our results indicate that even though MICT (walking on treadmill) and HIIT (on an elliptical) are effective intervention strategies in obese older adults, HIIT appears to have slightly more beneficial effects. More specifically, HIIT led to higher improvements than MICT on functional capacities, lean mass and skeletal muscle markers of mitochondrial content, fusion, and mitophagy. Thus, MICT but also HIIT (time-efficient training) could be recommended as exercise modalities for obese older adults to maintain or improve mobility, health and quality of life.
Characterization of vanadium-dependent bromoperoxidases involved in the production of brominated sesquiterpenes by the red alga Laurencia okamurae

ABSTRACT The red algal genus Laurencia produces abundant brominated metabolites, including cuparane- and laurane-type brominated sesquiterpenes. In order to gain insights into the biosynthesis mechanisms for brominated compounds, we focused on the vanadium-dependent bromoperoxidase (V-BPO). Four members of the homologous genes encoding for V-BPO were obtained from L. okamurae by PCR amplification. The recombinant V-BPO protein produced in Escherichia coli exhibited a significant brominating activity to monochlorodimedone. The function of V-BPO was examined by an assay using nerolidol as a relevant natural substrate. The enzyme properties of V-BPO were compared with those of related halogenating enzymes. The results indicate that V-BPO is one of the key enzymes responsible for the production of brominated compounds in Laurencia.
Design of Miniaturized Antipodal Vivaldi Antennas for Wideband Microwave Imaging of the Head

Many wideband applications, e.g., microwave imaging of the head, require low-frequency (~1–6 GHz) operation using small antennas. Vivaldi antennas are extensively used in multifarious wideband applications; however, the physical dimensions of the antenna become very large for covering low-frequency bands. Hence, the miniaturization of Vivaldi antennas, while maintaining proper matching and radiation characteristics, is essential for these applications. In this work, two miniaturized Vivaldi antennas are proposed, and several miniaturization techniques are presented for reducing the size of the antennas without the need for being immersed into any matching liquid, while maintaining desired performance. The novelty of the designs lies in the use of two half-cut superstrates, which help in achieving low-frequency operation with end-fire radiation. Two prototype antennas are fabricated, and the performances of the antennas are analyzed from both simulation and measurement results. The antennas show an FBW of 45.26% and 95.9% with a gain of ~1.9–5.2 dB and ~1.5–5.5 dB, respectively, while having a radiation efficiency above 80% within the resonant bandwidth. A comparison of the proposed antennas with several other state-of-the-art Vivaldi antennas is included to demonstrate the viability of the proposed antennas in achieving the desired performance with comparatively small dimensions.
