Implementation of USDA Smart Snack Standards in Minnesota Secondary Schools.

PURPOSE/OBJECTIVES: This study aimed to describe efforts by Minnesota public School Food Authorities (SFAs) to implement the Smart Snack regulations in secondary schools and challenges associated with implementing these regulations five years after they went into effect. METHODS: Public SFAs (n=452) in Minnesota were invited to complete an online survey that included up to 32 questions related to implementation of Smart Snack regulations in their competitive food sales: a la carte, vending machines, fundraisers, school stores/snack carts. Question formats included open-ended, multiple choice, select all that apply, and rating scale response from the following options: strongly disagree, disagree, agree, strongly agree, unsure/not applicable. Frequency of responses was calculated for each question with qualitative data analysis methods used to analyze responses to open-ended questions. RESULTS: A total of 247 responses was received (55% response rate). Most participants (95%) indicated they agree or strongly agree that they felt knowledgeable about the Smart Snack regulations, but over half (53.2%) indicated they agree or strongly agree that Smart Snacks are difficult to implement in secondary school sites. For all types of competitive food sales, the most frequent action taken in response to the Smart Snack regulations was to replace non-compliant foods with compliant foods. Failure to take action in response to Smart Snack regulations was reported as highest for fundraisers (18.9%) and school stores/snack carts (7.1%). CONCLUSIONS: The strategies and challenges identified in this study could be used to create targeted training and education materials to support school districts’ efforts to comply with Smart Snack regulations.
Efficient and Secure Multi-User Multi-Task Computation Offloading for Mobile-Edge Computing in Mobile IoT Networks

Mobile edge computing (MEC) is a new paradigm to alleviate resource limitations of mobile IoT networks through computation offloading with low latency. This article presents an efficient and secure multi-user multi-task computation offloading model with guaranteed performance in latency, energy, and security for mobile-edge computing. It does not only investigate offloading strategy but also considers resource allocation, compression and security issues. Firstly, to guarantee efficient utilization of the shared resource in multi-user scenarios, radio and computation resources are jointly addressed. In addition, JPEG and MPEG4 compression algorithms are used to reduce the transfer overhead. To fulfill security requirements, a security layer is introduced to protect the transmitted data from cyber-attacks. Furthermore, an integrated model of resource allocation, compression, and security is formulated as an integer nonlinear problem with the objective of minimizing the weighted sum of energy under a latency constraint. As this problem is considered as NP-hard, linearization and relaxation approaches are applied to transform the problem into a convex one. Finally, an efficient offloading algorithm is designed with detailed processes to make the computation offloading decision for computation tasks of mobile users. Simulation results show that our model not only saves about 46% of system overhead consumption in comparison with local execution but also scale well for large-scale IoT networks.
1 Bit Dual-Linear Polarized Reconfigurable Transmitarray Antenna Using Asymmetric Dipole Elements With Parasitic Bypass Dipoles

Reconfigurable transmitarray antennas with independent dual-linear polarization phase controlling capability are essential for wireless communications applications. This work proposes a novel 1 bit transmitarray element design at Ku-band, which adopts the receiver–transmitter structure with an active receiving dipole and a passive asymmetric transmitting dipole. The 1 bit phase shift is achieved by alternating two p-i-n diodes integrated on the active dipole to reverse its current direction. To mitigate the influence of p-i-n diodes and reduce the element insertion loss, a parasitic bypass dipole is added next to each dipole. Element simulations show that a low loss of only 1.0 dB is achieved. The dual-linear polarization capability is obtained by orthogonally interlacing two sets of proposed receiver–transmitter structures. A 100-element transmitarray prototype is designed, fabricated, and measured. The measured gain is 18.3 dB at 12.2 GHz, corresponding to an aperture efficiency of 22.6%. The 2-D beam-scanning capability for independent dual-linear polarization is experimentally verified and the scan angle covers ±50°. The measured maximum scan gain loss is 2.9 and 3.5 dB in the two principal planes, respectively.
Opening the Black Box of Team Performance With Open-Source Games: A Review and Recommendations

Many important indicators of the inputs, mediators, and outcomes of team performance have remained stubbornly resistant to sustained and detailed measurement. Team-based video games, now played by untold millions of people worldwide, offer the potential to provide data to support the analysis of these and other team-centered phenomena; however, theoretically grounded guidance is needed to guide game selection and modification to support such analysis. Accordingly, this article explores prospects and challenges for using currently available open video games (that is, ones which are free, open source, and open architecture) to improve understanding of team performance. The approach combines systematic classification, structured critique, and close analysis to identify games with strong potential for explorations of teamwork by human or mixed human-agent teams. This article concludes with a discussion of promising trajectories for future research.
Anger in Consumer Reviews: Unhelpful but Persuasive?

A common assumption in prior research and practice is that more helpful online reviews will exert a greater impact on consumer attitudes and purchase decisions. We suggest that this assumption may not hold for reviews expressing anger. Building on the theory of emotions as social information (EASI), we propose that although expressions of anger in a negative review tend to decrease reader perceptions of review helpfulness, the same expressions tend to increase the negative influence of the review on reader attitudes and decisions. Results from a series of laboratory experiments provide support for our claims. Our findings challenge the widely accepted assumption that more “helpful” reviews are ultimately more persuasive and extend the current understanding of the interpersonal effects of emotion in online communication. Our findings also suggest implications for review platforms, retailers, marketers, and manufacturers faced with the task of managing consumer reviews.
A Research Article: Comparison on Phytochemical Analysis and Antioxidant profile of two species of Ocimum (Ocimum basilicum and Ocimum sanctum)

Ocimum is a genus of aromatic annual and perennial herbs and shrubs of family Lamiaceae. There are number of species of this genus that are used to treat different types of disorders and diseases from ancient times. Out of those the two species i.e Ocimum sanctum and Ocimum basilicum were studied in the present article for their phytochemical testing and antioxidant activity and found that different extracts of these plants possessed various phytoconstituents such as alkaloids, glycosides, saponins, tannins, phenol, flavonoids and essential oils. And the methanol plant extracts of both plants exhibited antioxidant activity. The radical scavenging activity of plants was determined by DPPH scavenging method using Ascorbic acid as standard and it was found that % Scavenging activity of Ocimum basilicum was 53.6 ± 0.021 at 100 mcg/ml and 48.9 ± 0.034 at 100 mcg/ml in Ocimum sanctum respectively
Identification and Molecular Epidemiology of Mycobacterial Isolates in Kayseri/Turkey

Background: Early diagnosis and treatment of tuberculosis (TB) patients are the most effective ways to protect society from this disease. The objectives of this study were to evaluate the molecular epidemiology of mycobacterial strains by repetitive sequence PCR (rep-PCR) using the DiversiLab System method at Kayseri in Turkey. Methods: A total of fifteen clinically sample isolated Mycobacterial strains were identified as M. tuberculosis complex (MTBC) and non-tuberculous mycobacteria (NTM) by the rep-PCR method (bioMerieux), SD (Standard Diagnostics) rapid tests. Genotyping was performed by the rep-PCR method and clonal affinity was researched. Results: Nine of the strains were identified as MTBC and six strains were identified as NTM by the SD rapid test methods. Five of the strains were identified as NTM by the rep-PCR method as two M. scrofulaceum, M. chelonae, M. fortuitum and M. avium complex (MAC). By genotyping with rep-PCR a total of nine clones were identified, which included two main clones (A and B) and seven other clones (C, D, E, F, G, H, I). Conclusions: It was detected that rep-PCR test is useful method and can be used for the molecular epidemiology and for the identification of mycobacterial strains as they are rapid and practical. However, it is necessary to perform new studies for more mycobacterial strains using the methods described herein.
Physicochemical Properties and Oxidative Stability of Milk Fortified with Spray-Dried Whey Protein Concentrate–Iron Complex and In Vitro Bioaccessibility of the Added Iron

SUMMARY In the present study, spray-dried whey protein concentrate–iron (WPC–Fe) complex was prepared using a laboratory-scale spray drier under the optimized conditions of inlet temperature 180 °C, flow rate 2.66 mL/min and total solids 15% with the objective to make iron compatible with food products. In order to remove the free iron from the bound iron, standardised method involving centrifugation and ultrafiltration was employed. Further, the retentate was subjected to spray drying to produce WPC–Fe complex. Milk fortified with WPC–Fe complex (γ(iron)=15 mg/L) showed non-significant difference in heat stability, rennet coagulation time, colour estimation, curd tension, viscosity and sensory attributes as compared to control milk. In vitro bioaccessibility of iron and induction period of the fat from milk fortified with WPC–Fe complex were found to be slightly higher (p<0.05) than that of milk fortified with iron alone. Therefore, milk can be fortified with up to 15 mg/L iron in the form of WPC–Fe complex without significantly affecting its physicochemical properties.
Forest cover types as determinants of moth diversity in Indian Himalayan region

The relationship between forest cover types and moth species richness is poorly understood in Indian Himalayan region. In the present study simple and multiple linear regression model was analysed to understand the effect of area of three forest cover types (very dense forest, moderately dense forest and open forest) on species richness of moth families in Indian Himalayan region. It was found that out of 23 moth families reported from the Indian Himalayan region only one moth family (Bombycidae) had significant simple linear relationship with different forest cover types. Multiple linear regression modelling shows three forest cover types can explain more than 50% variation in total moth species richness and species richness in 10 moth families (Arctiidae, Bombycidae, Crambidae, Erabidae, Geometridae, Lasiocampidae, Pyralidae, Saturniidae, Sphingidae and Uraniidae). Our study suggests that forest cover types have great role in shaping moth species richness in Indian Himalayan region.
Conventional method and microwave drying kinetics of Laurus nobilis leaves: effects on phenolic compounds and antioxidant activity

Abstract Laurus nobilis constitutes one of the usually studied Mediterranean trees due to its therapeutic effects, nutritional properties, and ornamental use. In the current investigation, a comparative study was conducted between two types of drying methods, a microwave-assisted drying (MWD) (from 180 to 900 W) and a conventional method (open-air and oven-drying using temperatures from 40 °C to 120 °C). Drying kinetics were carried out as a function of moisture content according to time. Total Phenolic Content (TPC) as well as reducing power of obtained products were determined. Kinetic results showed that the time required for dried bay leaves became shorter as temperature and microwave power increased; drying with the microwave was much more efficient than conventional methods (open-air and oven-drying). Antioxidants of the Laurus nobilis leaves were better conserved using open-air and microwave drying. Our results underlined a significant correlation between TPC and reducing power. Microwave drying using 300 W during 130 s was the most efficient combination that provided dried bay leaves with the highest content of phenolic compounds and antioxidant activity.
A 22nm, 10.8 μ W/15.1 μ W Dual Computing Modes High Power-Performance-Area Efficiency Domained Background Noise Aware Keyword- Spotting Processor

This paper proposes a high power-performance-area efficient background noise aware keyword-spotting (KWS) processor based on an optimized binarized weight network (BWN). To reduce the power consumption while maintaining the system recognition accuracy for different background noise, the KWS processor with a SNR prediction module can be adaptively configured to use dual computing modes (standard computing mode and approximate computing mode) for both high recognition accuracy under high background noise and ultra-low power consumption under low background noise. The mel-scale frequency cepstral coefficients (MFCC) module is optimized with approximate computing technologies, which can reduce the power consumption by up to <inline-formula> <tex-math notation="LaTeX">$3.1\times $ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$5.7\times $ </tex-math></inline-formula> for high/low background noise, respectively. Based on the evaluation of the architecture design space exploration, an ultra-low power BWN accelerator with low voltage, area and leakage power and using precision self-adaptive approximate computing units was proposed. Evaluated under 22nm process technology, this work can support up to 10 keywords real time recognition with power consumption of <inline-formula> <tex-math notation="LaTeX">$15.1~\mu \text{W}$ </tex-math></inline-formula> for high background noise and <inline-formula> <tex-math notation="LaTeX">$10.8~\mu \text{W}$ </tex-math></inline-formula> for low background noise. Compared to the state-of-the-art KWS architectures, our work can achieve ultra-low power consumption (about <inline-formula> <tex-math notation="LaTeX">$1.7\times $ </tex-math></inline-formula> reduced), while maintaining high system capability and adaptability.
Acute Erythroid Leukemia: A Rare Case Report

AML with myelodysplasia related changes is an uncommon type of acute myeloid leukemia. It comprises less than 5% of acute leukemias. According to the recent World Health Organization (WHO-2016) classification, AML cases with ≥ 50% or more erythroid cells and ≥ 20% total myeloblasts should be diagnosed as AML with myelodysplasia-related changes. Morphologic cellular features help to establish the diagnosis. We present a rare case of AML with myelodysplasia related changes in a 35-year-old female who presented with low-grade fever, mild epistaxis, and shortness of breath and diffuse sternal tenderness. The peripheral smear showed features of pancytopenia with 6% blasts along with evidence of hemolysis. Bone marrow examination revealed erythroid hyperplasia with 65% erythroblasts and 24% myeloblasts. Flow cytometry was used for the confirmation of the diagnosis. The patient was administered chemotherapy with Azacitidine 75 mg/m2/day × 7 days in IV infusion along with 2 units of red cell concentrate prophylactically to prevent anemia. Molecular studies are needed to understand better the pathogenesis of AML with myelodysplasiarelated changes and to develop newer diagnostic and prognostic markers.
“REGOPLANT” AND “STIMPO” INFLUENCE ON THE CONTENT OF FREE AMINO ACIDS, PROLINE AND ON THE LIPID PEROXIDATION REACTION INTENSITY IN Helianthus annuus L. GROWN ON TECHNOSOL

The aim of study was to investigate the effect of new growth regulators “Stimpo” and “Regoplant”, produced by State Enterprise Interdepartmental Science and Technology Center — ISTC "Agrobiotech", on the proline and free amino acids content, and lipid peroxidation reactions intensity in comperison to the action of gibberellic acid and “Treptolem” (a second-generation growth regulator) in 14 day sunflower sprouts. The plants were cultured on soil substrates made from the coal mine rock waste of the Central Concentrating Factory in the Chervonohrad mining region. It was shown that the free amino acids and proline content increased, and the intensively of lipid peroxidation reactions (evaluated by the content of malonic dialdehyde) decreased. This indicated to the increase of plants resistance to unfavorable conditions of the coal mine rock under the action of the growth regulators studied. One could assump that “Stimpo” and “Regoplant” are promising agents in phytochemical treatment of coal mine rock dumps.
A Robust Fusion Method for Motion Artifacts Reduction in Photoplethysmography Signal

Robustness of estimating cardiorespiratory parameters from photoplethysmography (PPG) signal is highly dependent on the quality of the signal, which is heavily affected by motion artifacts. To increase the estimation accuracy of cardiorespiratory parameters, this article describes a novel fusion method to efficiently and effectively reduce the motion artifacts from the acquired PPG signal. The proposed fusion technique requires simultaneously acquiring data from a PPG sensor and accelerometer. To filter out the frequencies associated with motion, the method uses stopband filters with a central rejection frequency and bandwidth determined by the output signal of the accelerometer. Under such conditions, the proposed method to remove the motion artifacts does not depend on the quality of the reference signal and has almost no impact on the nature of PPG signals (i.e., amplitude, baseline, and periodicity). The effectiveness of the proposed method in the suppression of in-band and out-of-band frequencies of motion is numerically and experimentally evaluated. It is shown that the filtered PPG signal has sufficient information to estimate different cardiac parameters such as heart- (HR), respiration rate (RR), and blood oxygen saturation (SpO2). The motion artifact-free PPG signal obtained using our proposed method can estimate HR, RR, and SpO2 with an accuracy of above 95%. This level of accuracy confirms the usefulness of the proposed fusion method for accuracy improvement of cardiorespiratory parameters monitored by the filtered PPG signal.
An Efficient Piezoelectric Energy Harvesting Circuit With Series-SSHI Rectifier and FNOV-MPPT Control Technique

This article presents an efficient piezoelectric (PE) energy harvesting (EH) circuit based on the techniques of series synchronized switch harvesting on inductor (Series-SSHI) and maximum power point tracking (MPPT). The MPPT is achieved using the proposed fractional normal-operation voltage (FNOV) method, which is based on the Series-SSHI operating principle. The FNOV method no longer disconnects the PE harvester from the load circuit to measure its open-circuit (OC) voltage. Instead, it measures the peak PE voltage during the normal Series-SSHI operation to enable the continuous EH process. The FNOV-MPPT circuit is implemented based on a variable width hysteresis controller for saving energy. In addition, the prototyped circuit can achieve the figure of merit factor of 2.68 and the maximum MPPT efficiency of 98.1% with the PE OC voltage ranging from 2 to 5 V. The measurements confirm the validity of the proposed FNOV-MPPT solution for the weakly coupled PE harvesters.
Endophytes from the crop wild relative Hordeum secalinum L. improve agronomic traits in unstressed and salt-stressed barley

Abstract Agricultural crops growing in saline soils produce sub-optimal yields due to the negative effects of excess salts on plant growth and development. Salinity stress for crops is likely to increase as a result of climate change and the consequent salinisation of soils, particularly in coastal areas. In this study, we recovered fungal endophytes from the seeds of the wild barley relative Hordeum secalinum and tested their effects on a barley cultivar grown in a controlled environment under four levels of continuously applied salt stress: 0, 75, 150 and 250 mM NaCl. For the unstressed plants and plants stressed with 75 mM NaCl we found an endophyte-associated increase in early growth, grain dry weight, shoot dry weight, root dry weight, number of tillers, number of heads and number of grains. However, this relationship was reversed for the plants grown with 150 and 250 mM NaCl, where the endophytes negatively affected these traits. Plants stressed with the highest concentration of NaCl (250 mM) produced no grain. These results suggest that the endophytes may have potential to benefit field grown barley crops growing on moderately salt-stressed sites.
Fault-Tolerant Attitude Control of Small Spacecraft Using Robust Artificial Time-Delay Approach

This article presents a robust artificial time-delay-based attitude regulation control of a small spacecraft under the influence of parametric uncertainties, surrounding disturbances, and time-varying actuator faults. In the artificial time-delay (ATD) approach, the input–output information of the previous time instant is utilized to estimate the uncertain dynamical parts. The proposed attitude controller is designed by integrating the time-delay approach with a feedback control technique. Under the proposed composite control scheme, the system states are proved to be uniformly ultimately bounded (UUB) stable using the Lyapunov analysis. Moreover, the problem of unwinding in the quaternion representation, due to which the spacecraft consumes more time and energy, is also resolved under the proposed scheme. The performance of the proposed control methodology has been validated using numerical simulations. Furthermore, two different control schemes are also compared to illustrate the efficacy of the proposed strategy.
