Privacy-preserving targeted mobile advertising:A Blockchain-based framework for mobile ads
Authors: Ullah Imdad
Published: September 2020

The targeted advertising is based on preference profiles inferred via relationships among individuals, their monitored responses to previous advertising and temporal activity over the Internet, which has raised critical privacy concerns. In this paper, we present a novel proposal for a Blockchain-based advertising platform that provides: a system for privacy preserving user profiling, privately requesting ads from the advertising system, the billing mechanisms for presented and clicked ads, the advertising system that uploads ads to the cloud according to profiling interests, various types of transactions to enable advertising operations in Blockchain-based network, and the method that allows a cloud system to privately compute the access policies for various resources (such as ads, mobile user profiles). Our main goal is to design a decentralized framework for targeted ads, which enables private delivery of ads to users whose behavioral profiles accurately match the presented ads, defined by the ad system. We implement a POC of our proposed framework i.e. a Bespoke Miner and experimentally evaluate various components of Blockchain-based in-app advertising system, implementing various critical components; such as, evaluating user profiles, implementing access policies, encryption and decryption of users' profiles. We observe that the processing delay for traversing policies of various tree sizes, the encryption/decryption time of user profiling with various key-sizes and user profiles of various interests evaluates to an acceptable amount of processing time as that of the currently implemented ad systems.
Quantizing Radio Link Data Rates to Create Ever-changing Network Conditions in Tactical Networks
Authors: Rigolin F. Lopes Roberto , Loevenich Johannes , Rettore Paulo H. , M. Eswarappa Sharath , Sevenich Peter
Published: September 2020

Several sources of randomness can change the radio link data rate at the edge of tactical networks. Simulations and field experiments define these sources of randomness indirectly by choosing the mobility pattern, communication technology, number of nodes, terrain, obstacles and so on. Therefore, the distribution of change in the network conditions is unknown until the experiment is executed. We start with the hypothesis that a model can quantize the network conditions, using a set of states updated within a time window, to define and control the distribution of change in the link data rate before the experiment is executed. The goal is to quantify how much variation in the link data rate a tactical system can handle and how long it takes to resume IP data-flows after link disconnections. Our model includes functions to combine patterns of change together, transforming one pattern into another, jumping between patterns, and creating loops among different patterns of change. We use exemplary patterns to show how the change in the data rate impacts other link metrics, such as latency and jitter. Our hypothesis is verified with experiments using VHF radios over different patterns of change created by our model. We compute the inter-packet latency of three types of IP data-flows (broadcast, unicast and overlay) to highlight the time to resume data-flows after long link disconnections. The experimental results also support the discussion on the advantages and limitations of our model, which was designed to test tactical systems using military radios.
Review of Learning-Assisted Power System Optimization
Authors: Ruan Guangchun , Zhong Haiwang , Zhang Guanglun , He Yiliu , Wang Xuan , Pu Tianjiao
Published: September 2020

Machine learning, with a dramatic breakthrough in recent years, is showing great potential to upgrade the power system optimization toolbox. Understanding the strength and limitation of machine learning approaches is crucial to answer when and how to integrate them in various power system optimization tasks. This paper pays special attention to the coordination between machine learning approaches and optimization models, and carefully evaluates to what extent such data-driven analysis may benefit the rule-based optimization. A series of typical references are selected and categorized into four kinds: the boundary parameter improvement, the optimization option selection, the surrogate model and the hybrid model. This taxonomy provides a novel perspective to understand the latest research progress and achievements. We further discuss several key challenges and provide an in-depth comparison on the features and designs of different categories. Deep integration of machine learning approaches and optimization models is expected to become the most promising technical trend.
Oksidatiewe addisie van jodometaan aan Rh(I)- neokupferraatkomplekse as model vir ’n unieke toepassing van Tolman se beginsels
Authors: Venter JA
Published: September 2020

Oksidatiewe addisie is van groot belang in katalitiese prosesse. Die Monsantoproses vir die produksie van asynsuur is een van die bekendste voorbeelde hiervan. In ’n poging om onsekerhede betreffende die meganisme van oksidatiewe addisie op te klaar, is ons groep geïnteresseerd in die manipulering van die reaktiwiteit van die Rh(I)-senter van die [Rh(LL')(CO)(PR3)] tipe komplekse waar LL' enkelgelaaide bidentate ligande en PR3 verskillende monodentate fosfi enligande verteenwoordig. Hierdie fosfienligande varieer wat hulle elektroniese en steriese eienskappe betref en het soos die ander ligandvariasies ’n beduidende effek op die reaktiwiteit van die metaalsenter.

By die neokupferraatsisteem verloop oksidatiewe addisie met jodometaan via twee kompeterende paaie. Die k1-pad impliseer ’n nukleofiele aanval op CH3I wat tot ’n 16-elektron, vyfgekoördineerde intermediêr lei, waarvan die mate van ioonskeiding oplosmiddelafhanklik is. Die oplosmiddelondersteunde k2-pad kan as ’n uitsonderlike oksidatiewe addisie kataliseverskynsel beskou word. Deur die effek van variërende steriese en elektroniese eienskappe van die fosfienligande op die oksidatiewe addisie van die neokupferraatsisteem te bestudeer, kon ’n steries-elektroniese model, ontwikkel deur Tolman, toegepas word op die oksidatiewe addisiereaksies om die totale effek van die fosforligand in ’n bepaalde sisteem te evalueer. ’n Poging is aangewend om die fosfieneienskappe te kwantifi seer. Dit kan tot groter begrip rakende die samestelling en ontwerp van kataliste lei.
Substituente en isomeriese effekte op die reduksieen oksidasiepotensiaal van tris(β-diketonato) mangaan(III) komplekse: DFT en MESP analises
Authors: Adeniyi AA , Conradie J
Published: September 2020

Die reduksie van tris(β-diketonato)mangaan(III) ([Mn(β-diketonato)3]) verbindings na tris(β-diketonato)mangaan(II), asook die oksidasie daarvan tot tris(β-diketonato) mangaan(IV), is ondersoek met behulp van DFT-metodes. Die akkuraatheid van die voorspelling van die reduksiepotensiaal of oksidasiepotensiaal is baie belangrik vir die bepaling van die potensiaalomvang wat geskik is vir die ontwerp van spesifiek vereiste toepassings. Die DFT-funksionele metode M06 het die eksperimentele reduksiepotensiaal tot ‘n hoër vlak van akkuraatheid weergegee, in vergelyking met die M062X en B3LYP metodes. Hierdie studie het ook getoon dat reduksie van verbindings ‘n afname in entropie en ook Gibbs vrye energie, in sowel die gasfase as die oplosmiddelfase, veroorsaak het en gevolglik die hoogste waarde vir totale Gibbs reaksie-energie (ΔGrksie) vir die gereduseerde verbinding getoon het, veral vir dié molekules met sterker elektron-onttrekkende groepe, soos CF3. Dit het gelei tot ‘n reduksiepotensiaalverskuiwing na meer positiewe waardes, vir dié verbindings wat CF3 bevat. Hierdie meer positiewe reduksiepotensiaal van verbindings in die teenwoordigheid van sterker elektrononttrekkende groepe het ook ‘n skuif na meer positiewe oksidasiepotensiaal tot gevolg gehad. Gevolglik kon die oksidasiepotensiaal gaandeweg nie meer binne die eksperimentele venster vir oplosmiddels waargeneem word nie. Die waardes van die molekulêre elektrostatiese oppervlakpotensiaal (MESP) minima en die MESP atoompotensiaal van die Mn atoom en sy gekoördineerde suurstofatome, dien as goeie beskrywers vir die waargeneemde eksperimentele reduksiepotensiaal en kan ook bydra om die eksperimentele reduksie van toekomstige molekules tot ‘n hoë vlak van akkuraatheid te kan voorspel.

The invisible hole of cybersecurity insurance services
Authors: Pavel Tal , Gafni Ruti
Published: September 2020

This study examines the cybersecurity insurance market in the United States (U.S.) in order to reveal if an “invisible hole” of services and information exists in this market. This is performed by mapping the cybersecurity insurance services, offered by insurance companies, to cope with cybersecurity risks, and finding in which way these services are exposed, visible and comprehensive, in the insurance companies' websites. The research questions examined the extent cybersecurity insurance services offered by the main U.S. insurance companies; the visibility of such services on their websites; and the types of services offered. The sample included 44 insurance companies based upon nine lists of the top U.S. insurance companies. The findings present that most companies (68%) offer cybersecurity insurance services, while only a few (26.92%) expose such information in a visible way. Moreover, on the one hand, the insurance companies use general terms for services, which may be blur and ambiguous, while on the other hand, there is a widespread of specific services, most of them (81%) provided only by few companies. These findings may derive due to insufficient understanding of cybersecurity insurance clients' needs and may reflect the lack of maturity of the cybersecurity insurance market, as matured marketplaces are mostly more standardized. This study demonstrates that there is a long way to advance until the insurance market for cybersecurity risks will be mature, customers (businesses and organizations) will understand the needs for such insurance, and insurance companies will develop and offer relevant insurance services.

The owner's lack of knowledge about diseases and early handling of diseases in pets and the difficulty of seeing a veterinarian in urgent situations prevent pets from getting proper first aid. This study aims to identify the types of diseases suffered by pets based on the symptoms experienced by pets precisely. The method used is themethod Certainty Factor to accommodate the uncertainty of an expert's thinking on 12 diseases and 47 disease symptoms in pets. The results of this study can identify diseases in pets and produce certainty values ​​for the types of diseases in the form of diseases suffered by pets. So that this research can be a reference in identifying diseases in pets and providing knowledge to owners about first aid and disease management in pets.
Maladie de Still de l’adulte : que doit savoir le réanimateur ?
Authors: Gerfaud-Valentin Mathieu , Richard Jean-Christophe , Fauter Maxime , Sève Pascal , Jamilloux Yvan
Published: September 2020

La maladie de Still de l’adulte (MSA), actuellement classée parmi les pathologies autoinflammatoires multifactorielles, est une entité rare dont deux phénotypes sont individualisés : une forme rhumatismale articulaire chronique et une forme systémique mono- ou polycyclique. C’est au cours de cette dernière, souvent de façon inaugurale ou dans la première année d’évolution, que jusqu’à un tiers des patients présentent des complications pouvant engager le pronostic vital : syndrome d’activation lymphohistiocytaire, coagulation intravasculaire disséminée, myo-péricardite, insuffisance hépatique, voire défaillance multiviscérale. Après mise en place des traitements de suppléance adaptés, le médecin réanimateur devra alors entreprendre une démarche diagnostique systématique et, après élimination des diagnostics différentiels, proposer un traitement de ces formes graves de MSA reposant sur la corticothérapie à fortes doses, l’anakinra, et plus rarement la ciclosporine A ou le tocilizumab. Ces différents éléments font l’objet de cette mise au point.
Amelioration For Allergic Rhinitis and Asthma: The Treated Yeast Milmed and Physical Exercise
Authors: Trevor Archer
Published: September 2020

In the developed, industrial world, about 20% of people are affected by allergic rhinitis, about 6% of people have at least one food allergy, and about 20% have a topic dermatitis at some point in time. The global prevalence of allergies and asthma has increased, quite exponentially, during the last decades with WHO estimating above 400 million individuals debilitated by allergic rhinitis and 300 million by asthma; furthermore, 25-32% of European populations remain affected [1,2]. The postulated links between these conditions [3] demand a mandatory integration between to optimize treatment effects [2,4]. In some countries, up to 18% of people have asthma. Rates of many allergic diseases appear to be increasing. More than 150 million Europeans suffer from chronic allergic diseases and the current prediction is that by 2025 half of the entire EU population will be affected (EAACI, 2016).
Milmed Treatment Alleviated or Abolished Allergy
Authors: Trevor Archer
Published: September 2020

In view of the marked levels of discomfort, pain and/or poor health induced by allergic rhinitis and related conditions, especially during seasonal proclivities, the emerging availability of novel agents, and particularly probiotics, to (a) relieve, and (b) ameliorate those expressions offers much hope to sufferers whether afflicted by seasonal or regular, chronic allergies. The patented treated-yeast, Milmed, a probiotic suspension, previously shown to possess neuroprotective and neurorestorative properties, was found to provide marked ameliorative relief against a variety of allergic reactions and asthma expressed by a moderately-sized group of twenty-one participating-patients who had reported themselves to be chronic sufferers. Following a twelve-week course of Milmed treatment, an overwhelmingly large proportion (more than 95%) of the allergy-reporting patients indicated either "moderate" or "marked improvement" or were adjudged "symptom-free". Comparisons of the patients' allergy condition from before Milmed treatment to after indicated marked and significant improvements. Notably, in view of postal service vagaries that resulted in non-deliverance of Milmed, a significant correlation between post-treatment scores and missed weeks of Milmed was obtained (r = 0.526, p < 0.014). The possibility that 10- to 12-week administrations of Milmed may offer more-or-less long-lasting relief from allergic reactions and the inclusion of Milmed among the health-enhancing list of probiotic interventions ought to be examined more closely.
Real-World Data Evaluation Of Total IgE, Specific IgE And Omalizumab Therapy In A Cohort Of Allergic Asthma Patients Treated In A Community-Based Practice
Authors: Alabi Fortune O
Published: September 2020

Objective: In this study, we: (1) evaluated the correlation between total IgE and the presence of specific IgE; (2) compared the characteristics of patients with positive specific IgE to those with negative specific IgE; and, (3) analyzed the allergic testing results of patients on omalizumab and reported the effect of omalizumab on forced expiratory volume (FEV1) and asthma control test (ACT) results.

Methods: Data from patients diagnosed with allergic asthma and seen at Florida Lung, Asthma & Sleep Specialists (FLASS) between January 2016 and June 2019 were analyzed. Parameters evaluated were total IgE, and levels of specific IgE to antigens in the ImmunoCAP test and skin prick test (SPT). Additional parameters for patients on omalizumab therapy for at least 6 months were FEV1, % predicted FEV1 and ACT results.

Results: A total of 475 patients (114 males, 361 females) met the inclusion criteria. The mean age was 53 years (range: 17 to 89 years). Of these, 36 patients were not included in the analysis due to incomplete data.

Mean total IgE was higher in patients with positive ImmunoCAP results compared to those with negative results (396 KU/L vs. 81.3 KU/L).
There was a significant positive correlation between total IgE and levels of positive specific IgE in the ImmunoCAP test (p<0.0001, r=0.36, n=213 patients).
The correlation between total IgE and levels of positive allergens in SPT was not significant (p=0.15, n=44 patients)
Two positive reactions to allergens were seen in 22% of ImmunoCAP tests and 13% of SPT tests.
There was no statistically significant improvement in FEV1 (p=0.097, CI -0.17 to 0.02) and % predicted FEV1 (p=0.109, CI -6.63 to 0.70) in patients who used omalizumab for at least 6 months.
There was a statistically significant improvement in ACT scores (p=0.031, CI -4.21 to -0.21) in patients who used omalizumab for at least 6 months.
Conclusion: Allergic asthma could be seen in patients who had an absence of specific IgE in ImmunoCAP and a negative reaction to SPT. The benefit of omalizumab therapy is not limited to allergic asthma patients with positive specific IgE.

Cryogenic low-noise amplifiers for measurements with superconducting detectors
Authors: Novikov Ilya L , Ivanov Boris I , Ponomarev Dmitri V , Vostretsov Aleksey G
Published: September 2020

We designed, implemented, and characterized differential amplifiers for cryogenic temperatures based on Si bipolar junction transistor technology. The amplifiers show high gain values of more than 60 dB at 300, 77, and 48 K. The minimum voltage noise spectral density was achieved at 77 K and corresponded to 0.33 nV/Hz0.5 with a flicker noise of 20 Hz. The maximum voltage gain was 70 dB at 77 K for a frequency range from DC to 17 kHz. We experimentally show that the parallel differential circuit design allows for a reduction of the voltage noise from 0.55 to 0.33 nV/Hz0.5 at 77 K.

Some Die Filthy Rich: The Diverse Molecular Gas Contents of Post-starburst Galaxies Probed by Dust Absorption
Authors: Yesuf Hassen M. , Ho Luis C.
Published: September 2020

Quenched post-starburst galaxies (QPSBs) are a rare but important class of galaxies that show signs of rapid cessation or recent rejuvenation of star formation. A recent observation shows that about half of QPSBs have large amounts of cold gas. This molecular CO sample is, however, too small and is not without limitations. Our work aims to verify previous results by applying a new method to study a uniformly selected sample, more than 10 times larger. In particular, we present detailed analysis of Hα/Hβ ratios of face-on QPSBs at z = 0.02–0.15 and with

. We interpret the Hα/Hβ ratios by applying our recent gas mass calibration, which is based on non-PSB galaxies but predicts gas masses that are consistent with CO observations of ∼100 PSBs. We estimate the molecular gas by either using PSBs with well-measured Hα/Hβ ratios or measuring them from stacked spectra. Our analysis reveals that QPSBs have a wide range of Hα/Hβ ratios and molecular gas fractions that overlap with the typical gas fractions of star-forming or quiescent galaxies: Hα/Hβ ≈ 3–8 and

with median

, which correspond to

. Our results indicate that large reservoirs of cold gas are still present in significant numbers of QPSBs and that they arguably were not removed or destroyed by feedback from active galactic nuclei.
Heating Rates for Protons and Electrons in Polar Coronal Holes: Empirical Constraints from the Ultraviolet Coronagraph Spectrometer
Authors: Cranmer Steven R.
Published: September 2020

Ultraviolet spectroscopy of the extended solar corona is a powerful tool for measuring the properties of protons, electrons, and heavy ions in the accelerating solar wind. The large coronal holes that expand up from the north and south poles at solar minimum are low-density collisionless regions in which it is possible to detect departures from one-fluid thermal equilibrium. An accurate characterization of these departures is helpful in identifying the kinetic processes ultimately responsible for coronal heating. In this paper, Ultraviolet Coronagraph Spectrometer (UVCS) measurements of the H i Lyα line are analyzed to constrain values for the solar wind speed, electron density, electron temperature, proton temperature (parallel and perpendicular to the magnetic field), and Alfvén-wave amplitude. The analysis procedure involves creating a large, randomized ensemble of empirical models, simulating their Lyα profiles, and building posterior probability distributions for only the models that agree with the UVCS data. The resulting temperatures do not exhibit a great deal of radial variation between heliocentric distances of 1.4 and 4 solar radii. Typical values for the electron, parallel proton, and perpendicular proton temperatures are 1.2, 1.8, and 1.9 MK, respectively. Resulting values for the “nonthermal” Alfvén wave amplitude show evidence for weak dissipation, with a total energy-loss rate that agrees well with an independently derived total heating rate for the protons and electrons. The moderate Alfvén-wave amplitudes appear to resolve some tension in the literature between competing claims of both higher (undamped) and lower (heavily damped) values.

When galaxies merge, the supermassive black holes in their centers may form binaries and emit low-frequency gravitational radiation in the process. In this paper, we consider the galaxy 3C 66B, which was used as the target of the first multimessenger search for gravitational waves. Due to the observed periodicities present in the photometric and astrometric data of the source, it has been theorized to contain a supermassive black hole binary. Its apparent 1.05-year orbital period would place the gravitational-wave emission directly in the pulsar timing band. Since the first pulsar timing array study of 3C 66B, revised models of the source have been published, and timing array sensitivities and techniques have improved dramatically. With these advances, we further constrain the chirp mass of the potential supermassive black hole binary in 3C 66B to less than (1.65 ± 0.02) × 109 M
⊙ using data from the NANOGrav 11-year data set. This upper limit provides a factor of 1.6 improvement over previous limits and a factor of 4.3 over the first search done. Nevertheless, the most recent orbital model for the source is still consistent with our limit from pulsar timing array data. In addition, we are able to quantify the improvement made by the inclusion of source properties gleaned from electromagnetic data over “blind” pulsar timing array searches. With these methods, it is apparent that it is not necessary to obtain exact a priori knowledge of the period of a binary to gain meaningful astrophysical inferences.
Reproductive and recruitment seasons for Penaeus aztecus in the Tamaulipas-Veracruz area, Gulf of Mexico
Authors: Cervantes-Hernández Pedro , Gracia Adolfo
Published: September 2020

An integral fishery analysis was made for the population of Penaeus aztecus in the Tamaulipas-Veracruz area from 1974 to 1995. Fourteen age classes between 3 and 16 months old were found, and their respective total abundances were virtually reconstructed (this included shrimp that was caught and shrimp that were not caught in the study area). Age classes were statistically separated into two statistical population indices: the abundance of spawners (or SI index) and the abundance of recruits (or RI index).Time series were generated for these indices to establish when reproductive and recruitment seasons began, ended, and reached maximum abundance. SI index was structured with reproductive ages from 6 to 13 months old, and RI index with young recruits of 4 months old. Reproductive season (or lagoon recruitment) spanned from middle December to early May, with the highest spawners abundance in February. Recruitment season (or marine recruitment) spanned from early April to middle September, with the highest abundance of young recruits during June/July. The seasonal changes in the abundance of spawners were described with lagoon recruitment (in the marine environment). The seasonal changes in the abundance of recruits were described with marine recruitment (between lagoons systems and the marine environment). A higher exploitation level of spawners than for young recruits was recorded. Recently closure seasons are implemented between May and August/September/October. These completely protect marine recruitment, and the lagoon recruitment remains unprotected.
