Seed Longevity of Enterolobium contortisiliquum (Vell.) Morong

Abstract: Seed storage under controlled temperature and humidity maintains the viability and the vigor of seeds for a long time while preserving their longevity. Ex situ conservation in a seed storage chamber is perfect for simulating the cool dry conditions that are associated with long-term seed storage. This helps to preserve the availability of seeds for the recovery of degraded areas and to ensure a supply of propagating material for various purposes in silvicultural production, or as raw materials for biotechnological use. The present work evaluated the physical and physiological quality of Enterolobium contortisiliquum (Vell.) Morong seeds from an ex situ collection that was kept in a seed storage chamber at 6 °C ± 3 °C and with 60% ± 5% of RH in waterproof packaging. The water content, the physical quality by X-ray tests, germination, electrical conductivity, and the integrity and quality of RNA that was extracted from the embryonic axes were all determined. It was possible to identify full, damaged, malformed, translucent, and empty seeds. The seeds that had been stored for 1, 5, 9, and 10 years presented 78, 82, 42, and 38% of normal seedlings, respectively, while the lots of 6 and 7 years presented 0 and 6%. The seed storage conditions were the same for all of the lots. A water content higher than 6% influenced the quality of the seeds. The E. contortisiliquum seeds demonstrated high longevity. They could be stored for up to 10 years under controlled conditions.
>100-GHz Bandwidth Directly-Modulated Lasers and Adaptive Entropy Loading for Energy-Efficient >300-Gbps/λ IM/DD Systems

We demonstrate DML-based net 325-Gb/s at back-to-back and 321.24-Gb/s after 2-km standard single-mode fiber transmissions for >300-Gbps/λ short-reach optical interconnects. Our net rate performance denotes an increase of ∼34% compared to our previous works, while the pre-FEC rates are >400 Gbps. The DML transmitter is based on a PPR-enhanced, >100-GHz-bandwidth DML, fabricated by our novel membrane-III-V-on-SiC technology. Also wide-band, entropy-loaded DMT modulation is utilized based on a novel adaptive algorithm and via a digitally-preprocessed analog multiplexer. These results pave the way towards low-cost and energy-efficient Terabit Ethernet and a significant step towards achieving DML-based 400-Gbps/λ IM/DD systems in the future.
Semi-Analytical Path Delay Variation Model With Adjacent Gates Decorrelation for Subthreshold Circuits

The subthreshold circuit is a practical design style for the ultralow-power applications, but its timing estimation is a challenge due to the increasing local variation effects. The delay variation of adjacent gates is not independent because of input slew variation caused by the precedent gate, so their correlation effects are difficult to model and estimate. This article proposes a semi-analytical statistical delay model considering local variation for the subthreshold region, that is, the combination of analytical and simulation-based method. First, it decorrelates the slew influence between adjacent stages by dividing delay and output slew model into fast/slow input cases and dividing delay variation model into process variation and input slew variation. Then, it can be applied into multi-PVT conditions with a one-time SPICE nominal simulation by analyzing the independence of variability and relative variability of step input gate delay variance with output load capacitance and process, voltage, and temperature (PVT). Finally, experiments are carried out for different benchmarks, processes, voltages, and temperatures (BPVTs). The average errors of variance on different BPVTs are 4.8%, 3.1%, 4.0%, and 4.7%. Compared with other analytical works, the accuracies’ improvements of three metrics (variance, variability, and max delay) are <inline-formula> <tex-math notation="LaTeX">$8.3\times $ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$9.6\times $ </tex-math></inline-formula>, and <inline-formula> <tex-math notation="LaTeX">$2.7\times $ </tex-math></inline-formula> by the mean error at all test benchmarks. Compared with industrial method LVF, it has a comparable error in max path delay and runtime, and less three orders of magnitudes than LVF in characterization time and stored data (from TB to GB) at all test benchmarks.
Mutual synchronization pattern as a complementary indicator of the short-term blood pressure – heart rate feedback regulation activity

We suggest a complementary indicator of the blood pressure – heart rate feedback regulation based on their synchronization pattern assessed by Hilbert transform. We determine the synchronization coefficient Sync as the fraction of time fragments where the standard deviation of the differences between instantaneous phases of blood pressure and pulse intervals are below a certain threshold. While BRS characterizes the intensity of the pulse intervals response to the blood pressure changes during observed feedback responses, the Sync likely indicates how often such responses are activated in the first place. Data from 95 tilt test records indicate that in both healthy subjects and patients with moderate autonomic dysfunction BRS and Sync are typically reciprocal suggesting that low intensity of the feedback responses characterized by low BRS is rather compensated by their more frequent activation indicated by higher Sync. In contrast, in diabetes patients with autonomic neuropathy BRS and Sync are positively correlated likely indicating the breakdown of this compensation in some of the diabetic patients. Therefore we suggest that Sync could be used as an additional indicator of the blood pressure – heart rate feedback regulation activity that is complementary to the widely used baroreflex sensitivity (BRS).
Electromagnetic Interference (EMI) Shielding and Microwave Absorption Properties of Nickel Ferrite NiFe2O4/ PANI-PTSA Nanocomposite

ABSTRACT The Nickel ferrite (NiFe2O4) nanoparticle size was successfully prepared using the sol-gel method, while, the conducting polymer (PANI-PTSA) the chemical oxidative method was used. The nanocomposite {NiFe2O4/PANI-PTSA} is an excellent shielding material that reduces the cross-sectional area by absorbing radar waves at X-band, then offers protection from risky microwave radiation. The specimens NF, PNF1, PNF2 and PNF3 were characterised using some techniques, for instance, X-ray diffraction (XRD), Fourier transforms infrared (FTIR) and vector network analyser (VNA). Results showed that the specimen PNF3, which mixed by ratio (3:1) and 2.1 mm thickness, got better reflection loss (R.L); { – 19.5, – 25.19, – 59.08} dB, at frequency band {8.3, 9.5, 10.7} GHz, respectively, while the power absorption was (99 %), (>99.68%), (99.99 %) in that order. Here the nanocomposite {NiFe2O4/PANI-PTSA} adds new outcomes to the electromagnetic interference (EMI) for shielding and microwave absorption in various advanced military applications at frequency band (8–12 GHz).
Iron Modified Natural Zeolite as Sustainable Environmental Catalysts: Correlation between Iron Speciation and Catalytic Activity in NO-Reduction

Natural purified mordenite from Palmarito de Cauto (ZP) deposit, Cuba, was subjected to a hydrothermal ion exchange process in acid medium with Fe 2+ or Fe 3+ salts (Fe 2+ ZP and Fe 3+ ZP). The set of samples was characterized regarding their textural properties, morphology, and crystallinity, and tested in the NO reduction with CO/C3H6. Infrared spectroscopy coupled Prime Archives in Chemistry 3 www.videleaf. com with NO as a probe molecule was used to give a qualitative description of the Fe species’ nature and distribution. The exchange process caused an increase in the iron loading of the samples and a redistribution, resulting in more dispersed Fe 2+ and Fe 3+ species. When contacted with the NO probe, Fe 2+ ZP showed the highest intensity of nitrosyl bands, assigned to NO adducts on isolated/highly dispersed Fe 2+ /Fe 3+ extra-framework sites and FexOy clusters. This sample is also characterized by the highest NO sorption capacity and activity in NO reduction. Fe 3+ ZP showed a higher intensity of nitrosonium (NO + ) species, without a correlation to NO storage and conversion, pointing to the reactivity of small FexOy aggregates, and providing oxygen atoms for the NO to NO + reaction. The same sites are proposed to be responsible for the higher production of CO2 observed on this sample, and thus to be detrimental to the activity in NO SCR.

Abstract Histiopteris incisa is a core member to address the issue of relationship between Histiopteris and Pteris. Its complete chloroplast genome was generated by de novo assembly using Illumina sequencing. The complete chloroplast genome is a quadripartite structure of 16,0567 bp in length, with two inverted repeat regions (IRs) of 27,119 bp each, a large single-copy (LSC) region of 84,897 bp and a small single-copy (SSC) region of 21,432 bp. A total of 132 genes were predicted, involving in 88 protein-coding genes, eight rRNA genes, 35 tRNA genes, and one pseudogene. ML phylogenetic analysis showed that H. incisa was closely related to Pteridium aquilinum subsp. aquilinum.
A High-Efficiency Conformal Transmitarray Antenna Employing Dual-Layer Ultrathin Huygens Element

A high-efficiency conformal transmitarray with ultrathin dual-layer Huygens element is developed. The element consists of “I” shape patches for magnetic response and “T” shape stubs for electric response printed on two metal layers of a single substrate with only 0.5 mm thickness ( $\lambda _{0}$ /60 at 10 GHz). By tuning the magnetic and electric responses, the transmitting phase of the element can be changed. Eight elements are designed to cover quantized 360° phase range with a maximal 1.67 dB loss. Then, the proposed elements are employed in a small conformal transmitarray design. To improve the antenna efficiency, the elements’ dimensions are calculated by considering the oblique incidence effects. Finally, a cylindrically conformal transmitarray with a larger aperture size is simulated, fabricated, and measured. It can achieve a measured gain of 20.6 dBi with a 47% aperture efficiency.
Hybrid Phytase and Carbohydrases in Corn and Soybean Meal-Based Diets for Broiler Chickens: Performance and Production Costs

This study aimed to evaluate the effect of using 500 FTU/kg of hybrid phytase (created from three bacteria – Natuphos E), with or without xylanase and glucanase (560 TXU/kg; 250 TGU/kg) – Natugrain TS, in corn and soybean meal-based diets, with nutritional reductions in metabolizable energy (ME), Ca, and available phosphorus (AP), on performance parameters and production costs in broiler chickens. The 1875chickens were housed in boxes and distributed among 5 treatments with 15 replicates of 25 chickens each. The experiment included a positive control (the diet of which met the nutritional requirements of the birds), two negative controls (with ME reductions of 70 and 100 kcal/kg, and fixed reductions in Ca [0.16%] and AP [0.15%]), and two treatments with identical nutritional reductions in addition to enzyme supplementation. The treatments included the following: PC= positive control (basal diet (BD) corn and soybean meal); R_70 = BD with reduction of 70 kcal/kg, Ca and AP;R_100 = BD with reduction of 100 kcal, Ca and AP; R_70 + P =BD with reduction of 70 kcal/kg, Ca and AP + phytase (500 FTU/kg); R_100 + P + XG =BD with reduction of 100 kcal/kg, Ca and AP + phytase (500 FTU/kg) + xylanase (560 TXU/kg) + glucanase (250 TGU/kg). Performance parameters, carcass yield, and production costs (USD/ton chilled carcass) were evaluated. In conclusion, the reductions of 70 kcal/kg, 0.16% Ca, and 0.15% AP did not affect performance in chickens over 42 days, if diets were supplemented with hybrid phytase (500 FTU/kg). Supplementation with hybrid phytase and carbohydrases in diets with reductions of 100 kcal/ kg, 0.16% Ca, and 0.15% AP led to lower production costs.
EspialCog: General, Efficient and Robust Mobile User Implicit Authentication in Noisy Environment

Mobile authentication is a fundamental factor in the protection of user’s private resources. In recent years, motion sensor-based biometric authentication has been widely used for privacy-preserving. However, it faces with the problems including low data collection efficiency, insufficient authentication scenario coverage rate, weak de-noising ability, and poor robustness of models, rendering existing methods difficult to meet the security, privacy, and usability requirements jointly in the real-world scenario. To overcome these difficulties, we propose a system called EspialCog, which is able to 1) collect the sensor data embedded in mobile devices self-adaptively, unobtrusively and efficiently through the evolutionary stable participation game mechanism (ESPGM) with a high scenario coverage rate; 2) minimize noise from collected data by analyzing three types of abnormalities; and 3) authenticate the ownership of mobile devices in real-time by adopting optimized LSTM model with an enhanced stochastic gradient descent (SGD) algorithm. The simulation experiment on 6000 users shows that the efficiency and coverage rates increase dramatically by deploying our ESPGM. Moreover, we conduct experiments on a large-scale real-world noisy dataset with 1513 users and two other small pure real-world datasets. The experimental results show the high accuracy and favorable robustness of EspialCog in the noisy environment.
Water footprint analysis of temporary crops produced in São Carlos (SP), Brazil

This paper aims to evaluate the water footprint (WF) of temporary crops produced in the municipality of São Carlos, Brazil, between 2004 and 2017. The WF calculation was developed following the Water Footprint Network approach (WFN) and using CROPWAT model. The results were compared with the world averages and other studies that analyzed the same crops. We applied statistical tests to verify data behavior over the years and calculated correlation coefficients between WF components and crop yields. The results indicated low values of total WF for sugarcane (total average of 166.2 m3 ton-1) and tomato (total average of 97.2 m3 ton-1), while rice (total average of 5212.4 m3 ton-1) and groundnut (total average of 3865.8 m3 ton-1) showed the opposite. In general, WF components do not follow a monotonic trend, a normal distribution can be assumed and there is a statistically significant difference when comparing our findings with global mean values. These results ratify the importance of local WF studies, especially in Brazil, considering its importance in global agricultural market and the respective use of water resources.
Molecular Gas Dynamics and the Direct Simulation of Gas Flows

The direct simulation Monte Carlo (or DSMC) method has, in recent years, become widely used in engineering and scientific studies of gas flows that involve low densities or very small physical dimensions. This method is a direct physical simulation of the motion of representative molecules, rather than a numerical solution of the equations that provide a mathematical model of the flow. These computations are no longer expensive and the period since the 1976 publication of the original Molecular Gas Dynamics has seen enormous improvements in the molecular models, the procedures, and the implementation strategies for the DSMC method. The molecular theory of gas flows is developed from first principles and is extended to cover the new models and procedures. Note: The disk that originally came with this book is no longer available. However, the same information is available from the author's website (http://gab.com.au/)
Security Risk Management in E-commerce Systems: A Threat-driven Approach

E-commerce has transformed the commerce industry as we know it, introducing better purchasing, shipping, and customer services. These business services generate and utilise sensitive information such as customer purchases, ﬁnancial and personal information which are of high value to attackers. Securing e-commerce systems demands security risk management conscious of evolving security threats. This research work proposes and analyses a threat-driven approach that explores the use of a security threat analysis method – STRIDE to support a selected security risk management method – ISSRM (Information System Security Risk Management) in managing security risk in an e-commerce system. Results of this approach present e-commerce asset identiﬁcation, threat analysis, and risk identiﬁcation, with security risk treatment decisions. We discuss these results presenting the beneﬁts of the STRIDE and ISSRM combination.
Working Progress towards Lawn Mower Automation

This paper is a working progress towards an automation of the Spider lawn mower (SLM) which is a four synchronized steering wheel mobile robot. During the functioning, the SML must follow cutting grass edge with no overlapping of a strip of cut grass and also satisfy slippage constrains. To this end, a small prototype called Andromina which is a four-independent steering wheel mobile robot has been chosen to verify the control approach. This paper proposes to implement a mathematical model that takes into account the kinematics and dynamics of the mobile robot and also a nonlinear control strategy like the state feedback linearization. The most important advantage of the proposed model-control strategy is that it takes into account the nonlinearities of the system and a control law becomes a linear one. The path following tracking error has been verified by the statistical approach called analysis t-test and also results of real data simulations have shown the effectiveness of the proposed control strategy applied to a four-independent steering nonholonomic wheeled mobile robot.
Cerebrovascular Response to Phenylephrine in Traumatic Brain Injury: A Scoping Systematic Review of the Human and Animal Literature

Intravenous phenylephrine (PE) is utilized commonly in critical care for cardiovascular support. Its impact on the cerebrovasculature is unclear and its use may have important implications during states of critical neurological illness. The aim of this study was to perform a scoping review of the literature on the cerebrovascular/cerebral blood flow (CBF) effects of PE in traumatic brain injury (TBI), evaluating both animal models and human studies. We searched MEDLINE, BIOSIS, EMBASE, Global Health, SCOPUS, and the Cochrane Library from inception to January 2020. We identified 12 studies with various animal models and 4 studies in humans with varying TBI pathology. There was a trend toward a consistent increase in mean arterial pressure (MAP) by the injection of PE systemically, and by proxy, an increase of the cerebral perfusion pressure (CPP). There was a consistent constriction of cerebral vessels by PE reported in the small number of studies documenting such a response. However, the heterogeneity of the literature on the CBF/cerebral blood volume (CBV) response makes the strength of the conclusions on PE limited. Studies were heterogeneous in design and had significant limitations, with most failing to adjust for confounding factors in cerebrovascular/CBF response. This review highlights the significant knowledge gap on the cerebrovascular/CBF effects of PE administration in TBI, calling for further study on the impact of PE on the cerebrovasculature both in vivo and in experimental settings.
The Calculated Continuous Emission of a LTE Hydrogen Plasma.

The total continuous emission coefficient for a LTE hydrogen plasma at one atmosphere is calculated for a temperature range from 8000 to 16000 K and a wavelength range from 400 to 15000 Å. Contributions involving the species H, H 2 + , H-, and H2, as well as the wings of Stark-broadened hydrogen lines are included. This calculation will permit the radiation emitted from a laboratory hydrogen plasma to be used as a high intensity spectral radiance calibration standard.
Some aspect of perturbed extended general quasi variational inequality by using auxiliary principle technique

ABSTRACT Perturb Extended GQVI provide natural, unified, simple and novel context to study an extensive class of equilibrium problems arising in various fields. In this work, we familiarize and study a number of new and known computational approaches to solve new class of QVI with three nonlinear machinists by using different techniques including auxiliary approach and projection approach. We also deal with the existence of the solution of this newly established class of VI, as well as discuss the convergent theorem of the new algorithm by using the projection principal approach, which is simple as compared with other known classes of VI. Our consequences present an important enhancement of earlier recognized techniques for explaining various classes of VI. We are also debating several similar techniques as special cases. Several real-life equilibrium undeveloped problems have been proposed for further open new exploration horizon.
Evaluating the Information Usefulness of Online Health Information for Third-party Patients

Online health interactions (OHIs) can benefit patients, physicians, and society. However, little research has been conducted that studies the social value of OHIs for third-party patients who view previous OHIs concerning similar health issues to theirs. Drawing on the literature on social support and information uncertainty, this study established a theoretical model to explore the roles of treatment information, prevention information, and emotional support in determining information usefulness perceived by third-party patients, and whether such relationships are contingent on information uncertainty. The model was tested using “health questions and answers” textual data from 1,848 OHIs. The results indicate that prevention information and emotional support significantly improve information usefulness perceived by third-party patients. When the level of information uncertainty regarding physicians’ replies is high, the effect of treatment information is strengthened and the effect of emotional support is weakened, indicating both positive and negative contingent roles of information uncertainty. This study has implications for practitioners and also contributes to the literature on online health information, social support, information science, and information uncertainty.
