description: Elusive features in photonic and electronic devices can be detected by means of advanced, time-domain spectroscopic techniques. In this letter we introduce a novel kind of modulation spectroscopy, based on the optomechanical interaction of photonic and mechanical modes. Applying the technique to a Si metasurface and its drum-like mechanical modes, we detect narrow-band quasi-Bound-State-in-the-Continuum (q-BIC) modes close to normal incidence, where their measurement can be hindered by a high symmetry protection and undesired background modes. Showing a visibility enhancement of more than one order of magnitude, the optomechanical modulation spectroscopy can be an innovative tool for precise spectroscopy of a wide set of photonic devices, including the goal of measuring purely symmetry protected BIC resonances.

description: Benefit-risk assessment is a crucial step in medical decision process. In many biomedical studies, both longitudinal marker measurements and time to a terminal event serve as important endpoints for benefit-risk assessment. The effect of an intervention or a treatment on the longitudinal marker process, however, can be in conflict with its effect on the time to the terminal event. Thus questions arise on how to evaluate treatment effects based on the two endpoints, for the purpose of deciding on which treatment is most likely to benefit the patients. In this article, we present a unified framework for benefit-risk assessment using the observed longitudinal markers and time to event data. We propose a cumulative weighted marker process to synthesize information from the two endpoints, and use its mean function at a pre-specified time point as a benefit-risk summary measure. We consider nonparametric estimation of the summary measure under two scenarios: (i) the longitudinal marker is measured intermittently during the study period, and (ii) the value of the longitudinal marker is observed throughout the entire follow-up period. The large-sample properties of the estimators are derived and compared. Simulation studies and data examples exhibit that the proposed methods are easy to implement and reliable for practical use.

description: Identifying breakdowns in ongoing dialogues helps to improve communication effectiveness. Most prior work on this topic relies on human annotated data and data augmentation to learn a classification model. While quality labeled dialogue data requires human annotation and is usually expensive to obtain, unlabeled data is easier to collect from various sources. In this paper, we propose a novel semi-supervised teacher-student learning framework to tackle this task. We introduce two teachers which are trained on labeled data and perturbed labeled data respectively. We leverage unlabeled data to improve classification in student training where we employ two teachers to refine the labeling of unlabeled data through teacher-student learning in a bootstrapping manner. Through our proposed training approach, the student can achieve improvements over single-teacher performance. Experimental results on the Dialogue Breakdown Detection Challenge dataset DBDC5 and Learning to Identify Follow-Up Questions dataset LIF show that our approach outperforms all previous published approaches as well as other supervised and semi-supervised baseline methods.

description: In this article we review our work on the production of hadrons in the nuclear environment. We work with a string-breaking model for the initial production of hadrons and with a quantum-kinetic transport model (GiBUU) to describe the final state interactions of the newly formed (pre)hadrons. The latter are determined both by the formation times and by the time-development of the hadron-hadron cross section. We first show that only a linear time-dependence is able to describe the available hadronization data. We then compare with detailed data from HERMES and JLAB; very good agreement is reached in all reactions studied without any tuning of parameters. We also repeat predictions of spectra for pions and kaons at JLAB@12GeV. We finally explain the absence of CT effects in the recent experiment on proton transparencies in quasielastic (QE) events on nuclei. We propose to look instead for CT effects on protons in semi-inclusive DIS (SIDIS) events.

description: The non-Abelian gauge structure of the Standard Model implies the presence of the multi-boson self-interactions. Precise measurements in experimental and theoretical studies of these interactions allow not only testing the nature of the Standard Model but also new physics contribution coming from the beyond Standard Model. These interactions can be examined using a model-independent way in effective theory approach that composes the motivation part of this study. In this paper, we examine the anomalous $ZZγ$ and $Zγγ$ neutral triple gauge couplings via the process $e^{-} e^{+}\to Zγ$ for the neutrino-antineutrino pair decay of $Z$ boson. It has performed with both unpolarized and polarized electron beams at the Compact Linear Collider with $\sqrt{s}= 3$ TeV. The study focused on $CP$-conserving $C_{\widetilde{B}W}/{Λ^4}$ and $CP$-violating $C_{BB}/{Λ^4}$, $C_{BW}/{Λ^4}$, $C_{WW}/{Λ^4}$ couplings. Obtained sensitivities on the anomalous neutral triple gauge couplings with $95\%$ Confidence Level are given with systematic uncertainties of $0\%$, $5\%$ and $10\%$ for unpolarized, $-80\%$ and $80\%$ polarized electron beams with integrated luminosities of ${\cal L}_{\text{int}}=5$ $\rm ab^{-1}$, ${\cal L}_{\text{int}}=4$ $\rm ab^{-1}$ and ${\cal L}_{\text{int}}=1$ $\rm ab^{-1}$, respectively. Comparing the latest experimental limits and related phenomenological studies, our results on the anomalous neutral gauge couplings are set more stringent sensitivity between 10-30 times of magnitude.

description: Novel Internet-of-Things (IoT) access technologies are emerging as part of the next generation cellular networks. These technologies are specifically oriented towards energy-limited IoT devices that are scattered far away from their serving base station. One of the key methods of achieving deep coverage is via repeated transmissions of data. However, repetition leads to higher energy consumption and reduces the device battery-lifetime. Thus, a trade-off between coverage and energy consumption exists and requires careful investigation. This paper evaluates the effects of transmission repetition on enhancing the probability of coverage and the cost of the incurred energy. Using an empirical repetition profile based on traffic load and device distance from the base station, we derive the coverage probability and energy profile models for IoT links that utilize two different diversity combining techniques. In particular, we focus on two common diversity combining that are; (i) Selection Combining (SC), and (ii) Maximal Ratio Combining (MRC). We utilize tools from stochastic geometry to formulate an analytic framework that compares these two combining methods. This framework can aid network designers in jointly maximizing the network coverage while minimizing the energy expenditure of devices.

description: We present a nonparametric Bayesian joint model for multivariate continuous and categorical variables, with the intention of developing a flexible engine for multiple imputation of missing values. The model fuses Dirichlet process mixtures of multinomial distributions for categorical variables with Dirichlet process mixtures of multivariate normal distributions for continuous variables. We incorporate dependence between the continuous and categorical variables by (i) modeling the means of the normal distributions as component-specific functions of the categorical variables and (ii) forming distinct mixture components for the categorical and continuous data with probabilities that are linked via a hierarchical model. This structure allows the model to capture complex dependencies between the categorical and continuous data with minimal tuning by the analyst. We apply the model to impute missing values due to item nonresponse in an evaluation of the redesign of the Survey of Income and Program Participation (SIPP). The goal is to compare estimates from a field test with the new design to estimates from selected individuals from a panel collected under the old design. We show that accounting for the missing data changes some conclusions about the comparability of the distributions in the two datasets. We also perform an extensive repeated sampling simulation using similar data from complete cases in an existing SIPP panel, comparing our proposed model to a default application of multiple imputation by chained equations. Imputations based on the proposed model tend to have better repeated sampling properties than the default application of chained equations in this realistic setting.

description: Through Non-Terrestrial Networks (NTN), a global coverage connecting areas with minimal or no terrestrial services is envisaged using satellite and air-borne platforms. However, one of the challenges to delivering NTN communications is the increased levels of path-loss, relative to typical terrestrial scenarios, due to the vast communication distance towards satellite platforms. Typically, cellular IoT technologies adopt frame repetitions where many redundant data transmissions are included to enhance its success rate. This can be also extended to satellite links to counter the effect of long distance communications on the link budget. In this paper, we put forth an analytic framework that captures the repetition behavior based on the probability of line-of-sight (LoS), as it heavily influences the propagation conditions. We analyze the coverage performance in terms of the frame success rate, which allows us to tune the repetitions behavior to suit a given satellite admittance region. Furthermore, we obtain an optimal global average success rate by considering the availability of satellites. The presented framework can facilitate coverage enhancements for IoT-over-Satellite networks.

description: Dichloroethane is widely used as a solvent, degreasing agent and in a variety of commercial products, and is known for being a ubiquitous contaminant in the environment. Important sources principally include the emissions from industrial processes, improper consumption, storage, and disposal methods. In view of the fact that the mechanism of its genotoxicity has not been satisfactorily elucidated, the acute in vivo toxicological impact is assessed in Rattus norvegicus. A systematic investigation has been made involving the use of conventional methods along with molecular and flow cytometric approaches. The micronucleus and chromosomal aberration frequencies were significantly elevated in bone marrow cells exposed to three concentrations at multiple treatment durations indicating positive time- and dose-response relationships. The mitotic index significantly decreased in similar concentrations in contrast to normal control. Separate studies were performed on blood cells for comet assay. It revealed dichloroethane-induced DNA damage in all exposures readily explainable in a dose- and time-dependent manner. Recent molecular techniques were further employed using leukocytes for the cell apoptosis/cycle and mitochondrial membrane potential employing propidium iodide staining and rhodamine-123, respectively. The effect on mitochondrial membrane permeability, cell cycle phases, and the DNA damage was analyzed through flow cytometry. These indicators revealed dichloroethane treatment decreased the mitochondrial membrane potential, affected the cell cycle, and confirmed the DNA damage, leading to apoptosis of the cells of the immune system responsible for immunotoxic effects of dichloroethane on rat leukocytes.

description: The main motivation of this paper is to introduce the permutation Jensen-Shannon distance, a symbolic tool able to quantify the degree of similarity between two arbitrary time series. This quantifier results from the fusion of two concepts, the Jensen-Shannon divergence and the encoding scheme based on the sequential ordering of the elements in the data series. The versatility and robustness of this ordinal symbolic distance for characterizing and discriminating different dynamics are illustrated through several numerical and experimental applications. Results obtained allow us to be optimistic about its usefulness in the field of complex time series analysis. Moreover, thanks to its simplicity, low computational cost, wide applicability and less susceptibility to outliers and artifacts, this ordinal measure can efficiently handle large amounts of data and help to tackle the current big data challenges.

description: Despite the high prevalence of dry eye, many challenges exist when diagnosing the symptom and related diseases. Thus, novel biosensors are needed to detect changes in dry eye specific biomarker expression for screening and diagnostic applications. For this purpose, crosslinked synthetic polymers and plasmon-based sensing, were used as the recognition and signal transducing elements in the development of a low cost, label-free biosensor for detection of dry eye biomarkers in human tears. A library of poly(N-isopropylacrylamide)-based nanogels containing a custom aldehyde monomer, which forms covalent bonds with solvent accessible lysine residues present on the protein surface, and/or an anionic monomer (methacrylic acid) were fabricated. The concentrations of anionic and aldehyde monomers in the synthesized nanogels impacted their swelling behavior, charge character, and their protein binding behavior. The protein binding results obtained at the nanogel level indicated that electrostatic interactions are the main driving force behind protein-polymer interactions. Specifically, anionic nanogels possess recognition affinities towards high isoelectric point proteins (namely, lysozyme, lactoferrin, and IgG) in non-competitive buffered environments. In contrast, the incorporation and concentration of the aldehyde monomer capable of forming covalent interactions with select high isoelectric point tear proteins in the hydrogel coated gold nanoshells (AuNS), resulted in significant increases in protein detection through changes in the maximum localized surface plasmon resonance wavelength exhibited by the AuNS in non-competitive environments. Proof-of-concept testing of the developed hydrogel coated AuNS was performed in commercially available pooled human tears for label-free detection of two high isoelectric point proteins, lysozyme and lactoferrin, containing solvent accessible lysines. In a competitive diluted tear sample, protein binding to hydrogel coated AuNS was primarily governed by electrostatic interactions, similar to results obtained at the nanogel level. While our results revealed significant differences in protein binding when both ionic and covalent monomers were incorporated into the hydrogel coated AuNS in non-competitive protein environments, this result does not predict the outcome of the biosensor performance in a competitive biological environment. Instead, the results obtained demonstrate the cross-reactivity of the synthesized nanogels and hydrogel coated AuNS, an aspect which could be useful for future applications

description: Laser light scattering (LLS) and conductivity experiments were performed to investigate the effect of counterions on the conformation of polycarboxylate comb-like copolymers (PCEs) in aqueous solutions. The addition of monovalent ions (i.e., Na+ and K+) to dilute polycarboxylate comb-like copolymer solutions induced a slight shrinking of the molecular chains because of the screening of electrostatic intramolecular repulsion. Varying complexation phenomena, such as the formation of intramolecular complexation at certain Ca2+ concentrations and a transition between intermolecular and intramolecular complexations at different Ca2+ concentrations, were closely associated with Ca2+ concentration. Therefore, Ca2+ exerted a more complex influence on the conformation of PCEs with side chains containing polyethylene oxide (PEO) with different grafting densities. In addition, various combination types of Ca2+ with carboxylic groups were confirmed by theoretical simulation.

description: The mixed micellization of the anionic surfactant sodium oleate (NaOL) and three anionic surfactants (NaDC, AOT, SDS) of different structures in 0.01 mol/L NaCl solution was investigated by surface tension measurement at different temperatures. All the investigated mixtures exhibited nonideal behaviors as the experimental critical micelle concentration (CMC) values were less than the values calculated by using the Clint’s equation. Negative βm values calculated by using Rubingh’s equation and |ln(CMC1/CMC2)| < |βm| proved synergism in the three systems of higher αNaOL or lower αNaOL. An interesting phenomenon of double inflection points was observed for pure NaOL and mixtures of high αNaOL. The negative ΔG0m values for the mixed systems imply that the micelle formations are spontaneous process. The NaOL/NaDC system was also studied in buffer solution (pH 8, 12) at 30°C which also exhibited nonideal behavior. Synergism existed at pH 12 but not at pH 8 for the NaOL/NaDC system. It is noteworthy that there were no double inflection points for NaOL/NaDC system in buffer solution (pH 8, 12). Krafft point and calcium stability data show that these three anionic surfactants can improve the water solubility and hard-water resistance of soap.

description: This paper analyses the concept of growth in Bertrand Russell's educational thought. The aim is to show that, while Russell's concept is inexact in comparison with those of Whitehead and Dewey, it incorporates a humanistic conception of the individual based on his unique capacities. Education only succeeds in developing these in an atmosphere of freedom at observes the principle of reverence. Reverence goes beyond the simple non-interference implied by the principle of liberty of traditional liberalism and requires an active caring and nurturing on the part of the adult educator.

description: PrimPol is a DNA damage tolerance enzyme possessing both translesion synthesis (TLS) and primase activities. To uncover its potential role in TLS-mediated IgVλ hypermutation and define its interplay with other TLS polymerases, PrimPol−/− and PrimPol−/−/Polη−/−/Polζ −/− gene knockouts were generated in avian cells. Loss of PrimPol had no significant impact on the rate of hypermutation or the mutation spectrum of IgVλ. However, PrimPol−/− cells were sensitive to methylmethane sulfonate, suggesting that it may bypass abasic sites at the IgVλ segment by repriming DNA synthesis downstream of these sites. PrimPol−/− cells were also sensitive to cisplatin and hydroxyurea, indicating that it assists in maintaining / restarting replication at a variety of lesions. To accurately measure the relative contribution of the TLS and primase activities, we examined DNA damage sensitivity in PrimPol−/− cells complemented with polymerase or primase-deficient PrimPol. Polymerase-defective, but not primase-deficient, PrimPol suppresses the hypersensitivity of PrimPol−/− cells. This indicates that its primase, rather than TLS activity, is pivotal for DNA damage tolerance. Loss of TLS polymerases, Polη and Polζ has an additive effect on the sensitivity of PrimPol−/− cells. Moreover, we found that PrimPol and Polη-Polζ redundantly prevented cell death and facilitated unperturbed cell cycle progression. PrimPol−/− cells also exhibited increased sensitivity to a wide variety of chain-terminating nucleoside analogs (CTNAs). PrimPol could perform close-coupled repriming downstream of CTNAs and oxidative damage in vitro. Together, these results indicate that PrimPol's repriming activity plays a central role in reinitiating replication downstream from CTNAs and other specific DNA lesions.
The Element of Success In Transactions

description: There are differences between transactions and in expectations of success. The concept of success may not be borrowed from dissimilar transactions and applied indiscriminately in judging whether teaching acts have been executed. From a statement that one has taught something, only the intent to produce a desired outcome may be inferred. The actual results of teaching are not implicit within such a statement but require some determination of effectiveness.

description: We present a framework for gesture customization requiring minimal examples from users, all without degrading the performance of existing gesture sets. To achieve this, we first deployed a large-scale study (N=500+) to collect data and train an accelerometer-gyroscope recognition model with a cross-user accuracy of 95.7% and a false-positive rate of 0.6 per hour when tested on everyday non-gesture data. Next, we design a few-shot learning framework which derives a lightweight model from our pre-trained model, enabling knowledge transfer without performance degradation. We validate our approach through a user study (N=20) examining on-device customization from 12 new gestures, resulting in an average accuracy of 55.3%, 83.1%, and 87.2% on using one, three, or five shots when adding a new gesture, while maintaining the same recognition accuracy and false-positive rate from the pre-existing gesture set. We further evaluate the usability of our real-time implementation with a user experience study (N=20). Our results highlight the effectiveness, learnability, and usability of our customization framework. Our approach paves the way for a future where users are no longer bound to pre-existing gestures, freeing them to creatively introduce new gestures tailored to their preferences and abilities.

Increased Decision Making For Teachers
Creators: name: Imber, Michael
Publisher: name: Journal of Educational Thought / Revue de la Pensée Educative
Year: 2018

description: Noting that several new programs have afforded teachers increased opportunity for participation in educational decision making, the paper examines practical and ethical arguments which support this trend . The practical arguments, which are based on the promise of increased educational productivity (e.g . student achievement) , are found to be plausible but in need of confirmation through research . The ethical arguments are an application to teachers of the doctrine of workplace democracy, the notion that workers have the right to participate in making decisions that affect their work . It is concluded that both types of arguments must be considered in the development of policy.

The Asteroid Routing Problem: A Benchmark for Expensive Black-Box Permutation Optimization

description: Inspired by the recent 11th Global Trajectory Optimisation Competition, this paper presents the asteroid routing problem (ARP) as a realistic benchmark of algorithms for expensive bound-constrained black-box optimization in permutation space. Given a set of asteroids' orbits and a departure epoch, the goal of the ARP is to find the optimal sequence for visiting the asteroids, starting from Earth's orbit, in order to minimize both the cost, measured as the sum of the magnitude of velocity changes required to complete the trip, and the time, measured as the time elapsed from the departure epoch until visiting the last asteroid. We provide open-source code for generating instances of arbitrary sizes and evaluating solutions to the problem. As a preliminary analysis, we compare the results of two methods for expensive black-box optimization in permutation spaces, namely, Combinatorial Efficient Global Optimization (CEGO), a Bayesian optimizer based on Gaussian processes, and Unbalanced Mallows Model (UMM), an estimation-of-distribution algorithm based on probabilistic Mallows models. We investigate the best permutation representation for each algorithm, either rank-based or order-based. Moreover, we analyze the effect of providing a good initial solution, generated by a greedy nearest neighbor heuristic, on the performance of the algorithms. The results suggest directions for improvements in the algorithms being compared.

Reinforcement Learning Guided by Provable Normative Compliance

description: Reinforcement learning (RL) has shown promise as a tool for engineering safe, ethical, or legal behaviour in autonomous agents. Its use typically relies on assigning punishments to state-action pairs that constitute unsafe or unethical choices. Despite this assignment being a crucial step in this approach, however, there has been limited discussion on generalizing the process of selecting punishments and deciding where to apply them. In this paper, we adopt an approach that leverages an existing framework -- the normative supervisor of (Neufeld et al., 2021) -- during training. This normative supervisor is used to dynamically translate states and the applicable normative system into defeasible deontic logic theories, feed these theories to a theorem prover, and use the conclusions derived to decide whether or not to assign a punishment to the agent. We use multi-objective RL (MORL) to balance the ethical objective of avoiding violations with a non-ethical objective; we will demonstrate that our approach works for a multiplicity of MORL techniques, and show that it is effective regardless of the magnitude of the punishment we assign.

Soft Disability in Schools: Assisting or Confining At Risk Children and Youth?

Publisher: name: Journal of Educational Thought / Revue de la Pensée Educative
Year: 2018

description: The aim in this article is to examine the institutional construction of soft or mild disability by special education as a process of pre-incarceration in schools. Soft disability includes the categories of specific learning disabilities (LD), speech and language impairments (SLI), emotional and behavioural disorders (EBD), and mild mental retardation (MMR). Based on Foucault's (1975/1977) view of the link between prison and delinquency and Skrtic's (1995) critical-pragmatic perspective of disability and special education , I argue that labels of soft disability reflect a process of suspending the educational and citizenship participation of disadvantaged students. Similarly to what Foucault described as the production of delinquency by the prison, special education, by applying inconsistent identification criteria, increases the occurrence of soft disability. Variation and inquiry are outlined as alternative concepts whose implementation may r e verse the negative school dynamic between soft dis ability and (p r e) incarceration.

description: У статті проаналізовано деякі аспекти впливу цифровізації на адміністрування податків і зборів, компетенцію контролюючих органів. Зазначено, що в сучасних умовах процес впровадження цифрових технологій відбувається в усіх сферах суспільного життя. Досліджено правове регулювання компетенції контролюючих органів щодо адміністрування податків і зборів в умовах цифровізації. Акцентовано увагу, що завдання та повноваження Державної податкової служби України, які містяться в Положенні, корелюються із компетенцією податкових органів, яка закріплена в Податковому кодексі України. Однак, чітко не визначенні обов’язки таких органів; не використано термін «цифровізація», хоча прослідковується тенденція щодо цифровізації послуг, розвитку інформаційно-комунікаційних систем і технологій, роботи з електронними сервісами та платформами, базами даних, реєстрами; потребують розширення повноваження контролюючих податкових органів тощо.

Зазначено, що податкове законодавство вимагає комплексного підходу до оновлення. Запропоновано внесення змін і доповнень до відповідних нормативно-правових актів та розширення компетенції контролюючих податкових органів в умовах цифровізації щодо адміністрування податків і зборів; поліпшення координації та взаємодії на рівні формування та реалізації державної податкової політики через розширення повноважень податкових органів з питань цифрового розвитку, цифрових трансформацій та цифровізації центральних органів виконавчої влади та місцевих органів виконавчої влади; відокремлення функції з реалізації державної податкової політики та функції з адміністрування інформаційно-комунікаційних систем, баз даних Державної податкової служби України тощо.
