Rethinking Software Network Data Planes in the Era of Microservices

With the advent of Software Defined Networks (SDN) and Network Functions Vir-tualization (NFV), software started playing a crucial role in the computer network architectures, with the end-hosts representing natural enforcement points for core network functionalities that go beyond simple switching and routing. Recently, there has been a definite shift in the paradigms used to develop and deploy server applications in favor of microservices, which has also brought a visible change in the type and requirements of network functionalities deployed across the data center. Network applications should be able to continuously adapt to the runtime behavior of cloud-native applications, which might regularly change or be scheduled by an orchestrator, or easily interact with existing “native” applications by leveraging kernel functionalities - all of this without sacrificing performance or flexibility.
Conditional Moment Alignment for Improved Generalization in Federated Learning

In this work, we study model heterogeneous Federated Learning (FL) for classifi-1 cation where different clients have different model architectures. Unlike existing 2 works on model heterogeneity, we neither require access to a public dataset nor 3 do we impose constraints on the model architecture of clients and ensure that the 4 clients’ models and data are private. We prove a generalization result, that provides 5 fundamental insights into the role of the representations in FL and propose a theoret-6 ically grounded algorithm Fed erated C onditional M oment A lignment (Fed-CMA ) 7 that aligns class conditional distributions of each client in the feature space. We 8 prove the convergence and empirically, we show that Fed-CMA outperforms other 9 baselines on CIFAR-10, MNIST, EMNIST, FEMNIST in the considered setting
INFLUENCE OF FAN IDENTIFICATION AND PERCEIVED GROUP NORMS ON FANS' PURCHASING INTENTIONS TOWARDS CURRENT AND FORMER FOOTBALL CLUB SPONSOR

Sports, due to its publicity and social role is an exceptional channel for sponsorship activities. In addition to marketing of sports, goal of sports marketing is marketing through sports. This paper explores changes in fans’ buying intentions toward current and former sponsors when a change of a football club’s main sponsor occurs. Additionally, the role of fan identification and perceived group norms on purchasing intentions is explored. The research was conducted on a sample of 370 respondents. The results of hierarchical regression analysis show that fan identification and perceived group norms are significant predictors of purchasing intentions. Higher values of the Fan Identification and the Perceived Group Norms (PGN) indexes are related to the more pronounced intention to buy more often with the current and less often with the former sponsor. The research confirms the mediating role of PGN in relation to the HFI index and purchase intentions. This work contributes to knowledge by providing insights into the dynamics of fans’ purchase intentions in the specific situation of sponsor change.
Advances in Aptamer-Based Biosensors and Cell-Internalizing SELEX Technology for Diagnostic and Therapeutic Application

Aptamers are a group of synthetic single-stranded nucleic acids. They are generated from a random library of single-stranded DNA or RNA by a technology named systematic evolution of ligands by exponential enrichment (SELEX). SELEX is a repetitive process to select and identify suitable aptamers that show high affinity and specificity towards target cells. Great strides have been achieved in the design, construction, and use of aptamers up to this point. However, only a small number of aptamer-based applications have achieved widespread commercial and clinical acceptance. Additionally, finding more effective ways to acquire aptamers with high affinity remains a challenge. Therefore, it is crucial to thoroughly examine the existing dearth and advancement in aptamer-related technologies. This review focuses on aptamers that are generated by SELEX to detect pathogenic microorganisms and mammalian cells, as well as in cell-internalizing SELEX for diagnostic and therapeutic purposes. The development of novel aptamer-based biosensors using optical and electrical methods for microbial detection is reported. The applications and limitations of aptamers are also discussed.
Teachers’ Ontology-based Reasoning for Assessment in Student-centered Learning Environments

ABSTRACT We present an exploratory study on the use of ontologies for student assessment during a focus group with teachers in student-centred learning environments. The work is framed by a theoretical argument about coherence between instructional values and assessment systems, and how this may be achieved through a “community of judgment” with teachers at the centre. The purpose of the study was to understand the process and perceived usefulness of collaborative ontology development, at a narrative and conceptual level without grades or detailed probabilistic relationships. Findings of two kinds are discussed. First, we identified a set of framework-building moves used by teachers during ontology-based reasoning. Second, we present evidence that participants perceived the ontology development process to be useful and empowering in sharpening their ability to communicate nuanced assessment arguments.
A Study of 3CR Radio Galaxies from z = 0.15 to z = 0.65. II. Evidence for an Evolving Radio Structure

Radio morphology data have been collected for a sample of radio galaxies from the Revised Third Cambridge Catalog in the redshift range 0.15 < z < 0.65. Radio structure parameters including largest physical size, projected bending angle (β), lobe length asymmetry (Q), and hot spot placement (Fanaroff-Riley ratio) have been measured from the highest-quality radio maps available. Combined with similar data for quasars in the same redshift range, these morphology data are used in conjunction with a quantification of the richness of the cluster environment around these objects (the amplitude of the galaxy-galaxy spatial covariance function, Bgg) to search for indirect evidence of a dense intracluster medium (ICM). This is accomplished by searching for confinement and distortions of the radio structure that are correlated with Bgg. Correlations between physical size and hot spot placement with Bgg show evidence for an ICM only at z ≤ 0.4, but there are no correlations at z ≥ 0.4, suggesting an epoch of z ∼ 0.4 for the formation of the ICM in these Abell richness class 0–1, FR2-selected clusters. X-ray–selected clusters at comparable redshifts, which contain FR1 type sources exclusively, are demonstrably richer than the FR2-selected clusters found in this study. The majority of the radio sources with high Bgg values at z ≤ 0.4 can be described as "fat doubles" or intermediate FR2-FR1s. The lack of correlation between Bgg and β or Bgg and Q suggests that these types of radio source distortion are caused by something other than interaction with a dense ICM. Therefore, a large β cannot be used as an unambiguous indicator of a rich cluster around powerful radio sources. These results support the hypothesis made in our earlier paper that cluster quasars fade to become FR2s, then FR1s, on a timescale of 0.9 Gyr (for H0 = 50 km s-1 Mpc-1).
Inter-City Emotional Synchrony Is Conditional on Mobility Patterns

Recent research has attempted to document large-scale emotional contagion on online social networks. Despite emotional contagion being primarily driven by in-person mechanisms, less research has attempted to measure large-scale emotional contagion in in-person contexts. In this paper, I operationalize the temporal emotions associated with a particular city at particular points in time using sentiment analysis on Twitter data. Subsequently, I study how emotions converge between seven proximal cities in the state of Virginia, using two-way fixed effect models. I find that positive emotions tend to be synchronous between cities, but that effect is conditional on the level of contact between city residents at that period of time, as indicated by cell phone mobility data. I do not find any synchrony based on other types of emotions or general sentiment. I discourage drawing causal conclusions based on the presumed existence of several unmeasured sources of bias.
A differential fed wideband base station antenna with director and U‐shaped slot

In this article, a wideband base station antenna is designed. A new resonant mode is introduced into the antenna. Finally, four U‐shaped slots are added to the dipole of the antenna, and the antenna's third resonant mode is close to the first two resonant modes, which makes the antenna achieve wideband performance. The antenna is fabricated, and its performance is measured. The results show that the antenna has stable gain and radiation patterns. At the same time, the antenna works at 1.6–3.85 GHz with an impedance matching of −14 dB, and the relative bandwidth is 82%, the polarization isolation of the proposed antenna is better than −40 dB.
Goal-Oriented Physiotherapy Protocol of a 55-Year Male With Squamous Cell Carcinoma of the Tongue: A Case Report

Although oral cancer is well-known, the occurrence rate of the disease varies greatly globally. Squamous cell carcinoma of the tongue, which frequently starts in the lateral tongue, is the most common kind of oral cancer. In this instance, a male patient was found to have squamous cell carcinoma of the tongue and had undergone surgery. Following any surgical treatment of the tongue, discomfort, septicemia, difficulty eating, and speech issues are the most common oral consequences. His chief complaints were pain and difficulty in mouth opening. He also had the inability to move his tongue, which made talking and swallowing difficult. He had a history of chewing tobacco and smoking cigarettes for the past 15 years. A physiotherapy program was advised to the patient to reduce his symptoms, which included mouth-opening exercises, swallowing exercises, etc. The case's findings indicate that, when compared to the outcome measures, all objectives were met, and the patient improved in his activities of daily living.
Unconditionally secure key distillation from multiphotons

In this paper, we prove that the unconditionally secure key can be surprisingly extracted from multiphoton emission part in the photon polarization-based quantum key distribution. One example is shown by explicitly proving that one can indeed generate an unconditionally secure key from Alice's two-photon emission part proposed by Scarani [et al. Phys. Rev. Lett. 92, 057901 (2004)]. Which is called the Scarani-Acin-Ribordy-Gisin (SARG04) protocol. This protocol uses the same four states as in Bennett-Brassard 1984 (BB84) and differs only in the classical postprocessing protocol. It is, thus, interesting to see how the classical postprocessing of quantum key distribution might qualitatively change its security. We also show that one can generate an unconditionally secure key from the single to the four-photon part in a generalized SARG04 protocol that uses six states. Finally, we also compare the bit error rate threshold of these protocols with the one in the BB84 protocol and the original six-state protocol assuming a depolarizing channel.
SN 2016coi/ASASSN-16fp: an example of residual helium in a typeIc supernova?

The optical observations of Ic-4 supernova (SN) 2016coi/ASASSN-16fp, from ∼2 to ∼450 d after explosion, are presented along with analysis of its physical properties. The SN shows the broad lines associated with SNe Ic-3/4 but with a key difference. The early spectra display a strong absorption feature at ∼5400 A which is not seen in other SNe Ic-3/4 at this epoch. This feature has been attributed to He I in the literature. Spectral modelling of the SN in the early photospheric phase suggests the presence of residual He in a C/O dominated shell. However, the behaviour of the He I lines is unusual when compared with He-rich SNe, showing relatively low velocities and weakening rather than strengthening over time. The SN is found to rise to peak ∼16 d after core-collapse reaching a bolometric luminosity of Lp∼3 × 1042 erg s−1. Spectral models, including the nebular epoch, show that the SN ejected 2.5–4 M⊙ of material, with ∼1.5 M⊙ below 5000 km s−1, and with a kinetic energy of (4.5–7) × 1051 erg. The explosion synthesized ∼0.14 M⊙ of 56Ni. There are significant uncertainties in E(B − V)host and the distance, however, which will affect Lp and MNi. SN 2016coi exploded in a host similar to the Large Magellanic Cloud (LMC) and away from star-forming regions. The properties of the SN and the host-galaxy suggest that the progenitor had MZAMS of 23–28 M⊙ and was stripped almost entirely down to its C/O core at explosion.
Quinazolinone based hydroxamates as anti-inflammatory agents

Five thioether-linked hydroxamate/quinazolinone hybrid structures were synthesized and tested for their anti-inflammatory activities. The obtained results indicated that compounds 7a-c and 7e showed the inhibition on LPS-stimulated NO production with the IC50 values ranging from 58.03 to 66.19 mM. Molecular docking results showed that all synthesized compounds displayed affinity towards the 5-LOX, MK2, P2Y12, 15-PGDH, and DNA polymerase receptors based on the observed low binding energies and interactions with the key amino acids in the binding sites of the enzymes. Noticeably, compound 7e exhibited as a potential compound targeting six receptors including 5-LOX, MK2, mPGES-1, P2Y12, 15-PGDH, and DNA polymerase receptors.
In situ epitaxial growth of TiO2 on RuO2 nanorods with reactive sputtering

In this work, TiO2 deposition on RuO2 nanorods with reactive sputtering was studied. The TiO2 deposition was performed in situ after the RuO2 nanorod deposition at the same substrate temperature of 450 °C. The morphology examination and structure analysis have indicated a uniform and pure rutile TiO2 deposition on RuO2 nanorods. High-resolution transmission electron microscopy images also revealed an epitaxial growth of TiO2 on RuO2 nanorods. Such a low-temperature fabrication technique for one-dimensional (1D) heteronanostructure may apply to other functional materials. Since RuO2 is a good electric conductor, 1D heteronanostructures made from RuO2 nanorods are expected to exhibit enhanced functionality particularly in electrical and electrochemical applications.
Explosive Nucleosynthesis in Near-Chandrasekhar Mass White Dwarf Models for Type Iax Supernovae: Dependence on Model Parameters

The recently observed diversity of Type Ia supernovae (SNe Ia) has motivated us to conduct the theoretical modeling of SNe Ia for a wide parameter range. In particular, the origin of Type Iax supernovae (SNe Iax) has been obscure. Following our earlier work on the parameter dependence of SN Ia models, we focus on SNe Iax in the present study. For a model of SNe Iax, we adopt the currently leading model of pure turbulent deflagration of near-Chandrasekhar mass C+O white dwarfs (WDs). We carry out two-dimensional hydrodynamical simulations of the propagation of the deflagration wave, which leaves a small WD remnant behind and ejects nucleosynthesis materials. We show how the explosion properties, such as nucleosynthesis and explosion energy, depend on the model parameters, such as central densities and compositions of the WDs (including the hybrid WDs), turbulent flame prescription, and initial flame geometry. We extract the associated observables in our models and compare with the recently discovered low-mass WDs with unusual surface abundance patterns and the abundance patterns of some SN remnants. We provide the nucleosynthesis yield tables for applications to stellar archeology and galactic chemical evolution. Our results are compared with the representative models in the literature.
Magnetic monopoles in chiral magnets & frustrated magnetism on the swedenborgite lattice

This thesis deals with magnetic order in condensed matter systems and is divided into three parts. The first part gives a closed and self-contained introduction to the Monte Carlo methods used within this thesis with a special emphasis on a recently introduced feedback optimized parallel tempering algorithm. The second part deals with chiral magnets, i.e. magnets without inversion symmetry in their crystal structure. In these systems, weak spin-orbit coupling leads to the formation of smooth helical structures with a long periodicity. In 2009, the existence of a novel magnetic phase consisting of topological stable whirls, so-called skyrmions, was discovered in these materials. Due to their topological stability and the fact that they can be packed very densely, skyrmions are currently considered as promising candidates for future data storage applications. In this part of the thesis, I analyze how the topological protection of these objects is destroyed during the phase transition into another (non-topological) phase. It turns out that the underlying microscopic process is governed by the movement of monopoles of an emergent magnetic field created by the skyrmions. The third part of this thesis deals with frustrated spin systems. In these systems with antiferromagnetic interactions, a special lattice geometry excludes the simultaneous satisfaction of all competing interactions which often results in a macroscopic ground state degeneracy. Fluctuations between these different ground states prevent the system from developing long-range order and it remains disordered at all temperatures, which is why these systems are often referred to as "spin-liquids". Interestingly, there exists an intrinsic effect called "order-by-disorder", in which this degeneracy can be lifted at least partially at finite temperatures due to entropic reasons, provided that the ground states differ in their excitation spectra. I present the first detailed theoretical study of the recently synthesized swedenborgite compounds and show that these systems realize spin-liquid ground states both for the Ising and Heisenberg model. In the latter case, the order-by-disorder effect is found to result in the entropic preference of coplanar ground states at low temperatures.
The International Best Track Archive for Climate Stewardship (IBTrACS): unifying tropical cyclone data.

The goal of the International Best Track Archive for Climate Stewardship (IBTrACS) project is to collect the historical tropical cyclone best-track data from all available Regional Specialized Meteorological Centers (RSMCs) and other agencies, combine the disparate datasets into one product, and disseminate in formats used by the tropical cyclone community. Each RSMC forecasts and monitors storms for a specific region and annually archives best-track data, which consist of information on a storm's position, intensity, and other related parameters. IBTrACS is a new dataset based on the best-track data from numerous sources. Moreover, rather than preferentially selecting one track and intensity for each storm, the mean position, the original intensities from the agencies, and summary statistics are provided. This article discusses the dataset construction, explores the tropical cyclone climatology from IBTrACS, and concludes with an analysis of uncertainty in the tropical cyclone intensity record.
THE ORIGIN OF THE PUZZLING HARD X-RAY EMISSION OF γ CASSIOPEIAE

Massive B and Be stars produce X-rays from shocks in high-velocity winds with temperatures of a few million degrees and maximum X-ray luminosities of ≈1031 erg s−1. Surprisingly, a sub-group of early Be stars exhibits ≥20 times hotter X-ray temperatures and ≥10 times higher X-ray luminosities than normal. This group of Be stars, dubbed γ-Cas analogs, contains about 10 known objects. The origin of this bizarre behavior has been extensively debated in the past decades. Two mechanisms have been put forward: accretion of circumstellar disk matter onto an orbiting white dwarf, or magnetic field interaction between the star and the circumstellar disk. We show here that the X-ray and optical emissions of the prototype of the class, γ-Cas, are very well correlated on year timescales with no significant time delay. Since the expected migration time from internal disk regions that emit most of the optical flux to the orbit of the companion star is several years, the simultaneity of the high energy and optical flux variations indicates that X-ray emission arises from close to the star. The systematic lack of magnetic field detection reported in recent spectro-polarimetric surveys of Be stars is consistent with the absence of strong magnetic wind braking in these fast spinning stars but place strong constraints on the possible origin of the magnetic field. We propose that in γ-Cas, the magnetic field emerges from equatorially condensed subsurface convecting layers, the thickness of which steeply increases with rotation rate, and that γ-Cas and its analogs are the most massive and closest to critical rotation Be stars.
Recent Progress and Challenges on the Microfluidic Assay of Pathogenic Bacteria Using Biosensor Technology

Microfluidic technology is one of the new technologies that has been able to take advantage of the specific properties of micro and nanoliters, and by reducing the costs and duration of tests, it has been widely used in research and treatment in biology and medicine. Different materials are often processed into miniaturized chips containing channels and chambers within the microscale range. This review (containing 117 references) demonstrates the significance and application of nanofluidic biosensing of various pathogenic bacteria. The microfluidic application devices integrated with bioreceptors and advanced nanomaterials, including hyperbranched nano-polymers, carbon-based nanomaterials, hydrogels, and noble metal, was also investigated. In the present review, microfluid methods for the sensitive and selective recognition of photogenic bacteria in various biological matrices are surveyed. Further, the advantages and limitations of recognition methods on the performance and efficiency of microfluidic-based biosensing of photogenic bacteria are critically investigated. Finally, the future perspectives, research opportunities, potential, and prospects on the diagnosis of disease related to pathogenic bacteria based on microfluidic analysis of photogenic bacteria are provided.
Similarity transformations approach for a generalized Fokker-Planck equation

By using the similarity transformations approach, the exact propagator for a generalized one-dimensional Fokker-Planck equation, with linear drift force and space-time-dependent diffusion coefficient, is obtained. The method is simple and enables us to recover and generalize special cases studied through the Lie algebraic approach and the Green function technique.
Non-equilibrium Hadrochemistry in QGP Hadronization

This survey offers an introductory tutorial for students of any age of the currently thriving field of hadrochemistry. We discuss the different chemical potentials, how the hadronic phase space is described and how one evaluates the abundance of hadrons at time of hadronization. We show that a rather accurate description of experimental data arises and we present results of fits to hadron yields at SPS and RHIC. We show that introduction of chemical non-equilibrium originating in a sudden hadronization of a QGP is favored strongly at SPS and is presently also emerging at RHIC. The low chemical freeze-out temperatures are consistent with the picture of single freeze-out scenario (chemical and thermal freeze-out coincide).
