A Review of Blockchain-Based Access Control for the Industrial IoT

The rapid development and wide application of industrial Internet of things (IoT) have made network security issues such as identity authentication, access control, and data privacy more and more important in the distributed network environment, while blockchain technology benefiting from the advantages of decentralization, high confidence, and difficulty tampering are able to solve the trust problem existing in traditional access control technology. In this paper, firstly the basic concepts of access control and blockchain are explained, and the existing access control model and method based on blockchain in the industrial IoT scenario are summarized. Next, according to different implementation methods of blockchain, two technical routes are innovatively divided, i.e., the blockchain acts as a trusted entity (combination blockchain mode) in combination with the traditional access control technology, and the access control model constructed by completely utilizing the brand-new mode (full blockchain mode) of the distributed and non-tampering characteristics of the blockchain. From the angle of these two technical routes, the unique advantages of applying the blockchain to the IoT access control field are analyzed. Then, according to the key issues in the application of blockchain, the current research progress is summarized from the aspects of dynamic access control, space optimization on the chain, privacy data protection, etc. Finally, the further research direction is provided combined with the current challenges of access control mechanism based on industrial IoT.
MAP Adaptation Characteristics in Forensic Long-Term Formant Analysis

Forensic data from long-term formant analysis were used as input to the GMM-UBM approach, which is a way of deriving Likelihood Ratios. Tests were performed running 22 same-speaker comparisons and 462 different-speaker comparisons from a corpus of anonymized casework data involving telephone-intercepted speech. In a first series of tests, the number of Gaussian modules for GMM-modeling was increased from 1 to 32. In a second series of tests the duration of formant input in the compared files was reduced from 10 seconds to 5 and then to 2.5. All tests were performed both without and with the use of MAP adaptation. Results were evaluated in terms of overall performance characteristics EER and C llr and in terms of score distributions visualized as Tippett plots. The main goal of the study was to compare the use and non-use of MAP and to look at the practical forensic implications of the difference. Results show that in terms of overall performance characteristics there is little difference between the selection and de-selection of MAP. Tippett plot patterns however reveal strong differences. Application of MAP allows for more symmetric same-and different-speaker distributions and shows more robustness against duration reductions, both of which are forensically important.
Capturing the Experiences and Challenges of Emerging Adults in College During the COVID-19 Pandemic

Emerging adulthood (ages 18-30 years) coincides with “aging out” of pediatric care. As a result, combined internal medicine and pediatrics (Med-Peds) providers are tasked with promoting the health and well-being of this population during and post-coronavirus disease 2019 (COVID-19). In order to inform the response efforts, we aimed to capture emerging adults’ COVID-19 experiences and challenges during a two-week period of the pandemic in June 2020. We administered items from the California Health Interview Survey and an open-ended qualitative item via Qualtrics to 242 diverse emerging adults enrolled in a large US public university (mean age = 20.10, SD = 1.26). More than 90% of all students reported that they or their families or close friends experienced difficulties coping with the stressors and challenges presented by COVID-19. Almost half experienced financial difficulties and more than three-fourths experienced household disruptions during the pandemic. Qualitative findings underscored that these challenges were compounded by mental health and broader social issues. Recommendations for Med-Peds providers are provided to promote emerging adulthood health during and post-pandemic.
CO2 Mineralization Using Brine Discharged from a Seawater Desalination Plant

CO2 mineralization is a method of sequestering CO2 in the form of carbonated minerals. Brine discharged from seawater desalination is a potential source of Mg and Ca, which can precipitate CO2 as forms of their carbonate minerals. The concentration of Mg and Ca in brine are twice those in the seawater influent to desalination process. This study used a cycle for CO2 mineralization that involves an increase in the pH of the brine, followed by CO2 bubbling, and, finally, filtration. To the best of our knowledge, this is the first time that non-synthesized brine from a seawater desalination plant has been used for CO2 mineralization. The resulting precipitates were CaCO3 (calcite), Mg5(CO3)4(OH)2·4H2O (hydromagnesite), and NaCl (halite) with these materials being identified by X-ray Diffraction (XRD), Fourier transform infrared (FTIR) and thermo gravimetric-differentail thermal Analysis (TGA)-DTA. Despite the presence of Ca with Mg in brine being unfavorable for the precipitation of Mg carbonate, Mg reacted with CO2 to form hydromagnesite at a yield of 86%. Most of the Ca formed calcite, at 99% yield. This study empirically demonstrates that brine from seawater desalination plants can be used for CO2 mineralization.
BROADBAND SURFACE-MOUNT DIPOLE ANTENNA ARRAY USING HIGHLY ISOLATED VIA FENCE FOR 5G MILLIMETER-WAVE APPLICATIONS

Abstract—This letter proposes a 2× 2 surface-mount dipole antenna array based on via fence for 5G millimeter-wave applications. The dipole antenna element was first proposed, which has a compact size and low cost. Then via fences are introduced to reduce the coupling between adjacent elements and enhance isolation. In this way, compared with a 1×2 antenna array without the via fence, the isolation of a 1× 2 antenna array with a via fence is improved by 12 dB at 26GHz. The elements are extended into 2× 2 arrays with and without the via fence, and their performance is evaluated by the evaluation board. The measurement results show that the −10-dB impedance bandwidth of the antenna array is 19% (24.7–29.9GHz), and the peak gain is 9.5 dBi at 25GHz. The proposed 2× 2 array can be used in the N257 (26.5–29.5GHz), N258 (24.25–27.5GHz), and N261 (27.5–28.35GHz) frequency bands. Low cost, small size, and high isolation characteristics make it one of the candidates for 5G millimeter-wave applications.
Optimization of a Handwriting Method by an Automated Ink Pen for Cost-Effective and Sustainable Sensors

In this work, we present a do-it-yourself (DIY) approach for the environmental-friendly fabrication of printed electronic devices and sensors. The setup consists only of an automated handwriting robot and pens filled with silver conductive inks. Here, we thoroughly studied the fabrication technique and different optimized parameters. The best-achieved results were 300 mΩ/sq as sheet resistance with a printing resolution of 200 µm. The optimized parameters were used to manufacture fully functional electronics devices: a capacitive sensor and a RFID tag, essential for the remote reading of the measurements. This technique for printed electronics represents an alternative for fast-prototyping and ultra-low-cost fabrication because of both the cheap equipment required and the minimal waste of materials, which is especially interesting for the development of cost-effective sensors.
Assessing the validity of an ice core temperature profile generated from satellite data

This work analyses the relationship between RECAP data and a modelled ice core temperature profile created using DMI satellite data, initialised using the step model and the Crank-Nicolson numerical regime as well as the HerronLangway density model. Contrary to expectation, the cold bias caused by cloud-covered images in the satellite data initially appeared to be insignificant. However, this work suggests that disproportionate data removal due to cloud cover during the cold winter months causes a compensating bias. Additionally, the methodology described above verified that the T2M model contains a warm offset presumably caused by the two-metre height, as expected. Dette projekt analyserer forholdet mellem RECAP data og en iskerne temperaturprofil fremstillet med DMI satellitdata, initialiseret ved brug af step modellen, Crank og Nicolsons numeriske metode og Herron-Langway densitetsanalyse. Mod forventning var den kolde bias forårsaget af skydække i datasættet tilsyneladende ikke signifikant. Dog foreslår projektet at ujævn datasletning, grundet skydækket under den kolde vinter, producerer en bias som kompenserer. Derudover bruges de ovennævnte metoder til at bekræfte at T2M modellen er præget af et varmt offset, som forventet, formentligt grundet to-meter højden.
Effect of the planting season on carrot cultivars growth and yield in the brazilian semiarid region

In regions with high temperatures, carrot cultivation is impracticable, as high temperatures tend to reduce yield and quality of the product. However, with the advent of summer cultivars, carrot cultivation in these regions has become viable. The aim of this work was to evaluate the performance of ten carrot cultivars in different planting seasons. The experiments were carried out at the Rafael Fernandes Experimental Farm of the Federal Rural Semiarid University (UFERSA). The experiments were carried out in May, June, July and August of 2017. The experimental design was a randomized block with ten treatments and four repetitions. The characteristics that were evaluated were the root classification (long, average and short roots); commercial, non-commercial and total yield; dry plant weight and root fresh weight. Both the planting season and the cultivar played important roles in agronomic performance throughout the experimental period. In May and June, the highest average yields and plant growth were obtained (43 and 45 t ha-1 yield, respectively). Hybrid cultivars showed better performance than open-pollinated cultivars in terms of yield. The Brasília, BRS Planalto, and Kuronan varieties showed poor performance in all the evaluated characteristics.
Can Ethical Leadership Reduce Workplace Deviant Behavior?-- An Analysis Based on Localization Scale

Workplace Deviant Behavior of employees is harmful to the interests of other members and the organization. In order to reduce such behavior, the study aims to explore the influence mechanism of ethical leadership on Workplace Deviant Behavior by introducing the organizational ethical climate as a mediator variable and examine the role of its each dimension. Based on the Chinese context, researchers revised the three scales of ethical leadership, organizational ethical climate and Workplace Deviant Behavior to form the localized analysis tools. A sample survey including 528 employees from different types of enterprises and subsequent empirical analysis was conducted according to these localized scales. The results indicate that: Ethical leadership can significantly inhibit the occurrence of Workplace Deviant Behavior; Two dimensions of ethical climate of self-interest and rules completely mediate the inhibitory effect of ethical leadership on the interpersonal deviance; However, between the ethical leadership and organizational deviance, all the three dimensions of the organizational ethical climate play a partly intermediary role.
HPLC Method Development for the Fast Separation of a Complex Explosive Mixture

The growing threat of terrorism in many parts of the world has called for the urgent need to find rapid and reliable means of analyzing explosives. This is in view to help forensic scientists to identify different swabs from post-blast debris. The present study aims to achieve an efficient separation and identification of a mixture of sixteen explosive compounds (including nitroaromatics, nitramines, and nitrate esters) by high performance liquid chromatography using a diode array detection (HPLC/DAD) and an Agilent Poroshell 120 EC-120 C18 column at two wavelengths (235 and 214 nm). Relevant chromatographic parameters such as capacity factors, resolution, selectivity and number of theoretical plates have been optimized in order to achieve the best separation of the different components. In this respect, the effects of various parameters such as gradient time, column temperature, flow rate of mobile phase and initial percentage organic mobile phase on the separation of these compounds were investigated. It was revealed that the method allowed a fairly acceptable separation of all the compounds in less than 15 minutes except for two isomers, namely 4-A-2,6-DNT, 2-A-4,6-DNT and 2,6- DNT which could not be resolved by the used C18 column. This shortcoming notwithstanding, the developed method produced satisfactory results and demonstrated sensitive and robust separation, furthermore indicating that the HPLC developed method can be both fast and efficient for the analysis of complex mixtures of explosive compounds.

Organizational motivation plays a second-order role in adjusting organizational change and management innovation.
Incorporating Driver Relaxation into Factory Adaptive Cruise Control and its Implications on Traffic Operation

Current adaptive cruise control (ACC) systems adopt fixed desired time headway, which leads to an abrupt speed reduction after being cut-in by a lane changer in front or when changing lanes too close to the new leader. In contrast, human drivers behave differently and feature a variable spacing within 20 or 30 seconds right after a cut-in or lane change. Motivated by the smooth transition found in driver relaxation, the paper aims to incorporate relaxation into ACC systems. Based on the open-source ACC platform, Openpilot, Comma.ai, the paper proposes a feasible relaxation model compatible with current factory ACCs, which has also been tested using a market car with stock ACC hardware. The study further investigates the impact of relaxation ACC on traffic operation. Numerical simulation suggests that incorporating relaxation into ACC can help: i) reduce the magnitude of speed perturbations in both cut-in vehicles and followers; ii) stabilize the lane-changing traffic by reducing the speed variance and prevent the lateral propagation of congestion, and iii) increase the average vehicle speed and capacity in merging traffic.
Expression of LOX Suggests Poor Prognosis in Gastric Cancer

Background: Lysyl oxidase (LOX) is a key enzyme for the cross-linking of collagen and elastin in the extracellular matrix. This study evaluated the prognostic role of LOX in gastric cancer (GC) by analyzing the data of The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) dataset. Methods: The Wilcoxon rank-sum test was used to calculate the expression difference of LOX gene in gastric cancer and normal tissues. Western blot and immunohistochemical staining were used to evaluate the expression level of LOX protein in gastric cancer. Kaplan-Meier analysis was used to calculate the survival difference between the high expression group and the low expression group in gastric cancer. The relationship between statistical clinicopathological characteristics and LOX gene expression was analyzed by Wilcoxon or Kruskal-Wallis test and logistic regression. Univariate and multivariate Cox regression analysis was used to find independent risk factors affecting the prognosis of GC patients. Gene set enrichment analysis (GSEA) was used to screen the possible mechanisms of LOX and GC. The CIBERSORT calculation method was used to evaluate the distribution of tumor-infiltrating immune cell (TIC) abundance. Results: LOX is highly expressed in gastric cancer tissues and is significantly related to poor overall survival. Wilcoxon or Kruskal-Wallis test and Logistic regression analysis showed, LOX overexpression is significantly correlated with T-stage progression in gastric cancer. Multivariate Cox regression analysis on TCGA and GEO data found that LOX (all p < 0.05) is an independent factor for poor GC prognosis. GSEA showed that high LOX expression is related to ECM receptor interaction, cancer, Hedgehog, TGF-beta, JAK-STAT, MAPK, Wnt, and mTOR signaling pathways. The expression level of LOX affects the immune activity of the tumor microenvironment in gastric cancer. Conclusion: High expression of LOX is a potential molecular indicator for poor prognosis of gastric cancer.
Buried Aseismic Slip and Off‐Fault Deformation on the Southernmost San Andreas Fault Triggered by the 2010 El Mayor Cucapah Earthquake Revealed by UAVSAR

We use UAVSAR interferograms to characterize fault slip, triggered by the Mw 7.2 El Mayor‐Cucapah earthquake on the 1 San Andreas Fault in the Coachella Valley providing comprehensive maps of short‐term geodetic surface deformation that complement in situ measurements. Creepmeters and geological mapping of fault offsets on Durmid Hill recorded 4 and 8 mm of average triggered slip respectively on the fault, in contrast to radar views that reveal significant off‐fault dextral deformation averaging 20 mm. Unlike slip in previous triggered slip events on the southernmost San Andreas fault, dextral shear in 2010 is not confined to transpressional hills in the Coachella valley. Edge detection and gradient estimation applied to the 50‐m‐sampled interferogram data identify the location (to 20 m) and local strike (to <4°) of secondary surface ruptures. Transverse curve fitting applied to these local detections provides local estimates of the radar‐projected dextral slip and a parameter indicating the transverse width of the slip, which we equate with the depth of subsurface shear. These estimates are partially validated by fault‐transverse interferogram profiles generated using the GeoGateway UAVSAR tool, and appear consistent for radar‐projected slip greater than about 5 mm. An unexpected finding is that creep and triggered slip on the San Andreas fault terminate in the shallow subsurface below a surface shear zone that resists the simple expression of aseismic fault slip. We introduce the notion of a surface locking depth above which fault slip is manifest as distributed shear, and evaluate its depth as 6–27 m.
Effect of Comorbidity Burden on the Risk of Venous Thromboembolic Events After Total Knee Arthroplasty

Background Venous thromboembolic events (VTEs) are common after total knee arthroplasty (TKA). The rate of VTEs has improved with early mobilization, mechanical prophylaxis, and appropriate chemoprophylaxis. The aim of this study was to analyze the contribution of medical comorbidities to the risk of VTE after TKA Method Medicare claims from 2005 to 2014 were queried. International Classification of Diseases, Ninth revision (ICD-9), and Current Procedural Terminology codes were used to identify the diagnoses, procedures, and complications. 157,200 primary TKAs were age, sex, and Elixhauser Comorbidity Index (ECI) matched with 157,200 osteoarthritis controls. First instances of deep venous thrombosis (DVT) and pulmonary embolism were tracked at 90 days and 2 years. Odds ratios (ORs), confidence intervals, and P-values (p) were calculated and used to investigate the contribution of comorbidities. Results 90 days after TKA or OA diagnosis, comorbidities were associated with 45% of the DVT risk, 38% of the PE risk. 1 in 92 patients would be expected to be diagnosed with VTE after TKA and 1 in 136 patients after only the diagnosis of osteoarthritis. After 90 days, medical comorbidities were associated with 70% of the DVT risk, 68% of the PE risk. Conclusion Nearly 50% of DVTs and 40% of PEs within 90 days of TKA may be related to the baseline health of OA patients. Venous thromboembolic events after TKA are a “never” event according to Center of Medicare and services that appropriate VTE prophylaxis likely cannot be neutralized.
Paving Luteolin Therapeutic Potentialities and Agro-Food-Pharma Applications: Emphasis on In Vivo Pharmacological Effects and Bioavailability Traits

Luteolin is a naturally occurring secondary metabolite belonging to the class of flavones. As many other natural flavonoids, it is often found in combination with glycosides in many fruits, vegetables, and plants, contributing to their biological and pharmacological value. Many preclinical studies report that luteolin present excellent antioxidant, anticancer, antimicrobial, neuroprotective, cardioprotective, antiviral, and anti-inflammatory effects, and as a consequence, various clinical trials have been designed to investigate the therapeutic potential of luteolin in humans. However, luteolin has a very limited bioavailability, which consequently affects its biological properties and efficacy. Several drug delivery strategies have been developed to raise its bioavailability, with nanoformulations and lipid carriers, such as liposomes, being the most intensively explored. Pharmacological potential of luteolin in various disorders has also been underlined, but to some of them, the exact mechanism is still poorly understood. Given the great potential of this natural antioxidant in health, this review is aimed at providing an extensive overview on the in vivo pharmacological action of luteolin and at stressing the main features related to its bioavailability, absorption, and metabolism, while essential steps determine its absolute health benefits and safety profiles. In addition, despite the scarcity of studies on luteolin bioavailability, the different drug delivery formulations developed to increase its bioavailability are also listed here.
