On optimal linear codes of dimension 4
Authors: BONO Nanami , FUJİİ Maya , MARUTA Tatsuya
Published: May 2021

In coding theory, the problem of finding the shortest linear codes for a fixed set of parameters is central. Given the dimension $k$, the minimum weight $d$, and the order $q$ of the finite field $\bF_q$ over which the code is defined, the function $n_q(k, d)$ specifies the smallest length $n$ for which an $[n, k, d]_q$ code exists. The problem of determining the values of this function is known as the problem of optimal linear codes. Using the geometric methods through projective geometry, we determine $n_q(4,d)$ for some values of $d$ by constructing new codes and by proving the nonexistence of linear codes with certain parameters.

Published: May 2021

Human task performance studies are commonly used for detecting and identifying potential military threats. In this work, these principles are applied to detection of an environmental threat: the invasive Burmese python. A qualitative detection of Burmese pythons with a visible light camera and an 850 nm near-infrared (NIR) camera was performed in natural Florida backgrounds. The results showed that the difference in reflectivity between the pythons and native foliage was much greater in NIR, effectively circumventing the python’s natural camouflage in the visible band. In this work, a comparison of detection performance in the selected near-infrared band versus the visible band was conducted. Images of foliage backgrounds with and without a python were taken in each band in daylight and at night with illumination. Intensities of these images were then calibrated and prepared for a human perception test. Participants were tasked with detecting pythons, and the human perception data was used to compare performance between the bands. The results show that the enhanced contrast in the NIR enabled participants to detect pythons at 20% longer ranges than the use of visible imagery.

Published: May 2021

Temporally broadened ultrashort laser pulses impart thermal effects in the system under study even with nJ energies at high repetition rates (HRRs). The absorption induced accumulated thermal effects are prominent in materials with higher absorption. A numerical and experimental study with the help of a Z-scan has been carried out to estimate the nonlinear thermo-optic parameters of graphene by varying the input pulse duration ranging from sub-ps (100 fs) to a few ps (2.3 ps) at 780 nm. It is well known that for longer input pulses (in ns range), the thermal effects are high. In this study, we have found that the thermal effects in the sub-ps to few ps regime also result in a higher value of the thermo-optic nonlinear refractive index. Finite difference method calculations have been used to simulate the effect on the nonlinear phase shift under HRR fs pulses. The study has been found to be consistent with experiments. The experimental results along with the numerical simulation provide the importance of the contribution of the thermally induced refractive index change under HRRs within a few ms after excitation.

Authors: Kawamura Tomonari , Shirakawa Akira , Saito Kazuya
Published: May 2021

Multicore photonic crystal fiber (MC-PCF) can scale the output power with the number of cores by spatial beam combining if the in-phase mode is selected. We demonstrated simultaneous realization of phase-locked and mode-locked laser using Yb-doped 7-core MC-PCF by a semiconductor saturable absorber placed in the near-field inside a resonator. High energy 333 nJ pulses were obtained directly from a mode-locked fiber laser oscillator at a 42.4 MHz repetition rate with an average power of 14.1 W at 24 W excitation. We observed the direct output pulse width of 52 ps assuming a sech2 profile. However, it might be noise-like pulses because of no variation when we performed pulse compression. Single-pulse operation was achieved by increasing the bandwidth of the intracavity filter. In this case, 137 nJ, 42.4 MHz pulses were generated with a 5.8 W average power and the compressed output pulse width was 8.6 ps.

Published: May 2021

The transmission of airborne pathogens represents a major threat to worldwide public health. Ultraviolet light irradiation can contribute to the sanification of air to reduce the pathogen transmission. We have designed a compact filter for airborne pathogen inactivation by means of UVC LED sources, whose effective irradiance is enhanced thanks to high reflective surfaces. We used ray-tracing and computational fluid dynamic simulations to model the device and to maximize the performance inside the filter volume. Simulations also show the inhibition of SARS-Cov-2 in the case of high air fluxes. This study demonstrates that current available LED technology is effective for air sanification purposes.
Bi-functional tunable reflector/high-Q absorber design using VO2 assisted graphene-coated cylinder array
Authors: Hayati Raad Shiva , Atlasbaf Zahra
Published: May 2021

In this paper, a bi-functional tunable reflector/absorber device using an assembly of graphene-coated cylindrical wires, backed by a thermally controlled phase change material, is proposed. The reflection coefficient of the graphene-coated wire-grating manifests multiple resonances, originating from the hybridized excitation of localized surface plasmons in the graphene shells. The first plasmonic resonance (with the order of two), in the free-standing configuration, shows tunable near-perfect reflection while the second plasmonic resonance (with the order of three), in the reflector-backed array, exhibits near-perfect absorption. Because of the metal-insulator transition in the phase change material, it is feasible to switch between these two functionalities using a VO2 back layer. Moreover, the high-quality factor of the absorption band (Q ∼ 128.86) is due to its Fano line shape, leading to a narrow bandwidth. Thus, the absorbing mode can be possibly used for refractive index sensing with the sensitivity of S ∼ 9000 nm/RIU (refractive index unit) and figure of merit of FOM ∼ 104 RIU−1. In the proposed structure, different optical, material, and geometrical parameters affect the optical response of the operating bands, offering a flexible design.
Stimulated Brillouin scattering mitigation using optimized phase modulation waveforms in high power narrow linewidth Yb-doped fiber amplifiers
Authors: Panbiharwala Yusuf , Harish Achar Vasant , Feng Yujun , Venkitesh Deepa , Nilsson Johan , Srinivasan Balaji
Published: May 2021

We demonstrate the mitigation of stimulated Brillouin scattering (SBS) in a double-clad single mode Yb-doped optical fiber amplifier through external phase modulation of narrow linewidth laser radiation using optimized periodic waveforms from an arbitrary waveform generator. Such optimized phase modulation waveforms are obtained through a multi-objective Pareto optimization based on a comprehensive model for SBS in high power narrow linewidth fiber amplifiers using Brillouin parameters determined from controlled measurements. The ability of our approach to mitigate SBS is tested experimentally as a function of RMS linewidth of the modulated optical radiation, and we measure an enhancement in SBS threshold with respect to optical linewidth of ∼ 10 GHz−1. Furthermore, we discuss the dependence of the SBS threshold enhancement on key parameters such as the amplifier length and the period of the optimized waveforms. Through simulations we find that waveforms of sufficiently long periods and optimized for a relatively long fiber (10 m) are effective for SBS suppression for shorter fibers as well. We also investigate the effect of increase in the bandwidth and amplitude of the modulation waveform on the SBS threshold enhancement observed at higher optical linewidth.

Published: May 2021

We propose a rapid tomographic vibrometer technique using an optical comb to measure internal vibrations, transient phenomena, and tomographic distributions in biological tissue and microelectromechanical system devices at high frequencies. This method allows phase-sensitive tomographic measurement in the depth direction at a multi-MHz scan rate using a frequency-modulated broadband electrooptic multi-GHz supercontinuum comb. The frequency spacing was swept instantaneously in time and axisymmetrically about the center wavelength via a dual-drive Mach–Zehnder modulator driven by a variable radio frequency signal. This unique sweeping method permits direct measurement of fringe-free interferometric amplitude and phase with arbitrarily changeable measurement range and scan rate. Therefore, a compressive measurement can be made in only the depth region where the vibration exists, reducing the number of measurement points. In a proof-of-principle experiment, the interferometric amplitude and phase were investigated for in-phase and quadrature phase-shifted interferograms obtained by a polarization demodulator. Tomographic transient displacement measurements were performed using a 0.12 mm thick glass film and piezo-electric transducer oscillating at 10–100 kHz with scan rates in the range 1–20 MHz. The depth resolution and precision of the vibrometer were estimated to be approximately 25 µm and 1.0 nm, respectively.
High-field THz pulses from a GaAs photoconductive emitter for non-linear THz studies

Published: May 2021

We report the emission of high-field terahertz pulses from a GaAs large-area photoconductive emitter pumped with a Ti:Sapphire amplifier laser system at 800 nm wavelength and 1 kHz repetition rate. The maximum estimated terahertz electric field at the focus is ≳ 230 kV/cm. We also demonstrate the capability of the terahertz field to cause a non-linear effect, which usually requires high-field terahertz pulses generated through optical rectification or an air plasma. A significant drop in the optical conductivity of optically pumped GaAs due to Γ-L inter-valley scattering of free electrons caused by the strong THz field is found.

Published: May 2021

We present a novel, to the best of our knowledge, InGaAs/InAlAs single-photon avalanche diode (SPAD) with a triple-mesa structure. Compared with the traditional mesa structures, the horizontal distribution of the electric field decreases dramatically, while the peaks of the electric field at the mesa edges are well eliminated in the triple-mesa structure, leading to an excellent suppression of the surface leakage current and premature breakdown. Furthermore, the temperature coefficient of the breakdown voltage was measured to be as small as 37.4 mV/K within a range from 150 to 270 K. Eventually, one of the highest single-photon detection efficiencies of 35% among all the InGaAs/InAlAs SPADs with a decent dark count rate of

Probing the topology of the two-photon bands via time-dependent quantum walks
Authors: Stepanenko Andrei A. , Gorlach Maxim A.
Published: May 2021

Topological protection of quantum correlations opens new horizons and opportunities in quantum technologies. A variety of topological effects has recently been observed in qubit networks. However, the experimental identification of the topological phase still remains challenging, especially in the entangled many-body case. Here, we propose an approach to independently probe single- and two-photon topological invariants from the time evolution of the two-photon state in a one-dimensional array of qubits. Extending the bulk-boundary correspondence to the two-photon scenario, we show that an appropriate choice of the initial state enables the retrieval of the topological invariant for the different types of the two-photon states in the interacting Su–Schrieffer–Heeger model. Our analysis of the Zak phase reveals additional facets of topological protection in the case of collapse of bound photon pairs.

Authors: Lin Ziting , Lv Riqing , Zhao Yong , Zheng Hongkun , Wang Xixin
Published: May 2021

A special open-cavity Mach–Zehnder salinity sensor is presented and verified in this
Letter, which has obvious advantages in salinity sensitivity and loss.
The open-cavity structure is composed of a short section of etched
double-side hole fiber spliced between a pair of multimode fibers and
connected in series between a pair of single-mode fibers, which is the
SMF-MMF-etched DSHF-MMF-SMF structure proposed in the paper. According
to the experiment results, when the cavity length is about 100 µm, the
salinity sensitivity of the sensing probe can reach 2 nm/‰, and its
refractive index (RI) sensitivity can be more than 10,000 nm/RIU,
while having a low loss of

and a detection limit of 0.23‰.
Based on its characteristics, the sensor is a prospective online
monitor of ocean salinity. At the same time, it also provides a
low-cost way to construct an open cavity instead of femtosecond
inscribing.

Published: May 2021

In this Letter, a magnetically driven rotary microfilter that enables switching the modes of filtering and passing is fabricated in microfluidic devices via two-photon polymerization using a femtosecond laser for selective filtering of particles. The high-quality integration of a microfilter is ensured by accurately formulating the magnetic photoresist and optimizing the processing parameters. By changing the direction of the external magnetic field, the fabricated microfilter can be remotely manipulated to rotate by desired angles, thereby achieving the “filtering” or “passing” mode on demand. Taking advantage of this property, the magnetically rotary microfilter realizes multi-mode filtering functions such as capturing 8 µm particles/passing the 2.5 µm particles and passing both particles. More importantly, the responsive characteristic increases the reusability of the microchip. The lab-on-chip devices integrated with remotely rotary microfilters by the femtosecond laser two-photon polymerization with the functional photoresist will offer extensive applications in chemical and biological studies.

In this work, we describe the CRIMSON (CardiovasculaR Integrated Modelling and SimulatiON) software environment. CRIMSON provides a powerful, customizable and user-friendly system for performing three-dimensional and reduced-order computational haemodynamics studies via a pipeline which involves: 1) segmenting vascular structures from medical images; 2) constructing analytic arterial and venous geometric models; 3) performing finite element mesh generation; 4) designing, and 5) applying boundary conditions; 6) running incompressible Navier-Stokes simulations of blood flow with fluid-structure interaction capabilities; and 7) post-processing and visualizing the results, including velocity, pressure and wall shear stress fields. A key aim of CRIMSON is to create a software environment that makes powerful computational haemodynamics tools accessible to a wide audience, including clinicians and students, both within our research laboratories and throughout the community. The overall philosophy is to leverage best-in-class open source standards for medical image processing, parallel flow computation, geometric solid modelling, data assimilation, and mesh generation. It is actively used by researchers in Europe, North and South America, Asia, and Australia. It has been applied to numerous clinical problems; we illustrate applications of CRIMSON to real-world problems using examples ranging from pre-operative surgical planning to medical device design optimization.

Authors: A. Hamid Mohamad Shariff , Sazlina Shariff Ghazali
Published: May 2021

Shoulder rotator cuff tendinopathy is a common debilitating condition that affects a person daily function and the quality of life. Despite its frequent occurrence, the best treatment is still inconclusive. This review assessed the clinical effect of platelet-rich plasma injection for rotator cuff tendinopathy. A systematic literature search was conducted using CINAHL, Medline, SCOPUS, SPORTSDiscus and Web of Science databases to retrieve articles published in peer-reviewed journals until December 2020. Randomised controlled trials (RCTs), which compared clinical effects of PRP injection to the usual care among adults diagnosed with rotator cuff conditions were reviewed. The main outcomes of interest were changes in shoulder pain symptoms and shoulder functions. All variables were analysed using random effects meta-analyses. Eight RCTs were reviewed in this study. The risk of bias for randomization was low for 6 RCTs, one study had unclear risk and the other was a high risk. Studies vary on the PRP techniques including preparation and injections. Moreover, the control intervention also differs. Four studies compared PRP with normal saline injection while in the remaining 4 RCTs the control intervention were rehabilitation program and dry needling. Meta-analysis of selected studies showed that PRP injection was safe and effective intervention for long-term pain control and shoulder function in patients with RC disorders.

Published: May 2021

Spinal cord ischemia leads to iatrogenic injury in multiple surgical fields, and the ability to immediately identify onset and anatomic origin of ischemia is critical to its management. Current clinical monitoring, however, does not directly measure spinal cord blood flow, resulting in poor sensitivity/specificity, delayed alerts, and delayed intervention. We have developed an epidural device employing diffuse correlation spectroscopy (DCS) to monitor spinal cord ischemia continuously at multiple positions. We investigate the ability of this device to localize spinal cord ischemia in a porcine model and validate DCS versus Laser Doppler Flowmetry (LDF). Specifically, we demonstrate continuous (>0.1Hz) spatially resolved (3 locations) monitoring of spinal cord blood flow in a purely ischemic model with an epidural DCS probe. Changes in blood flow measured by DCS and LDF were highly correlated (r = 0.83). Spinal cord blood flow measured by DCS caudal to aortic occlusion decreased 62%. This monitor demonstrated a sensitivity of 0.87 and specificity of 0.91 for detection of a 25% decrease in flow. This technology may enable early identification and critically important localization of spinal cord ischemia.
Mixed-precision weights network for field-programmable gate array
Authors: Fuengfusin Ninnart , Tamukoh Hakaru
Published: May 2021

In this study, we introduced a mixed-precision weights network (MPWN), which is a quantization neural network that jointly utilizes three different weight spaces: binary {−1,1}, ternary {−1,0,1}, and 32-bit floating-point. We further developed the MPWN from both software and hardware aspects. From the software aspect, we evaluated the MPWN on the Fashion-MNIST and CIFAR10 datasets. We systematized the accuracy sparsity bit score, which is a linear combination of accuracy, sparsity, and number of bits. This score allows Bayesian optimization to be used efficiently to search for MPWN weight space combinations. From the hardware aspect, we proposed XOR signed-bits to explore floating-point and binary weight spaces in the MPWN. XOR signed-bits is an efficient implementation equivalent to multiplication of floating-point and binary weight spaces. Using the concept from XOR signed bits, we also provide a ternary bitwise operation that is an efficient implementation equivalent to the multiplication of floating-point and ternary weight space. To demonstrate the compatibility of the MPWN with hardware implementation, we synthesized and implemented the MPWN in a field-programmable gate array using high-level synthesis. Our proposed MPWN implementation utilized up to 1.68-4.89 times less hardware resources depending on the type of resources than a conventional 32-bit floating-point model. In addition, our implementation reduced the latency up to 31.55 times compared to 32-bit floating-point model without optimizations.
Understanding importance of clinical biomarkers for diagnosis of anxiety disorders using machine learning models
Authors: Sharma Amita , Verbeke Willem J. M. I.
Published: May 2021

Anxiety disorders are a group of mental illnesses that cause constant and overwhelming feelings of anxiety and fear. Excessive anxiety can make an individual avoid work, school, family get-togethers, and other social situations that in turn might amplify these symptoms. According to the World Health Organization (WHO), one in thirteen persons globally suffers from anxiety. It is high time to understand the roles of various clinical biomarker measures that can diagnose the types of anxiety disorders. In this study, we apply machine learning (ML) techniques to understand the importance of a set of biomarkers with four types of anxiety disorders—Generalized Anxiety Disorder (GAD), Agoraphobia (AP), Social Anxiety Disorder (SAD) and Panic Disorder (PD). We used several machine learning models and extracted the variable importance contributing to a type of anxiety disorder. The study uses a sample of 11,081 Dutch citizens’ data collected by the Lifelines, Netherlands. The results show that there are significant and low correlations among GAD, AP, PD and SAD and we extracted the variable importance hierarchy of biomarkers with respect to each type of anxiety disorder which will be helpful in designing the experimental setup for clinical trials related to influence of biomarkers on type of anxiety disorder.
Rethinking luxury brands and sustainable fashion business models in a risk society
Authors: Olatubosun Posi , Charles Erica , Omoyele Tolulope
Published: May 2021

This exploratory work investigates the burgeoning integration of ‘cradle to cradle’ practices into primary strategic activities of procurement, production and sales by ten London based fashion businesses, analysing how profits are derived from offsetting the high costs of sustainable inputs against savings from innovative strategic choices in the production value chain. This research was influenced by the background knowledge that in the global fashion industry, less than 1 per cent of the recycled textiles are converted into new wearable materials, and even more of these textiles end up in landfills. However, this unsustainable tradition in the fashion industry may gradually give way to a mainstream circular economic best practice in the fashion industry, even as the Mckinsey Report found that sustainability will be a significant factor for consumer purchasing mass market apparels by 2025. Based on the semi-structured interview of the ten fashion business owners and the analyses of internal strategic policy documents including budgets, we adopted Garret Hardin’s ‘Tragedy of the Commons’ and Ulrich Beck’s risk society as the lens view through which the qualitative data derived from these fashion businesses were discussed in order to bring out the illustrative extracts and sub-themes. Through the application of interpretive methodological approach, we were able to generate the themes suggesting the ‘Becksian’ reflexive modernization and dis-embedding mechanisms in analysing the issue of trust in luxury fashion environment. We were able to demonstrate the multidisciplinary and multifaceted nature of the use of modern technology in achieving a closed-loop circular economy in luxury fashion business(es) and its interconnectedness within the concentric layers of the value-chain, which is part of the economy, which is in turn a subset of the society and the environment. As businesses are expected to adapt their strategies to the changing environment, we argue that dematerialization in fashion is still at its infancy, and some deliberate actions on the part of economic policy-makers may be required in due course as this is connected to social sustainability amongst others. This article contributes new empirical data to the understanding of luxury fashion business in a circular economy, which is a departure from the linear economy with its attendant externalities. The adoption of a sustainable fashion business model may be pivotal to combating the inefficiency costs built into the fashion industry, and if successful, may be replicated in other jurisdictions in due course.
Antibacterial effect of acidic ionized water on horse wounds bacterial isolates
Authors: Rahman Afiqah Zafirah Abdul , Adzahan Noraniza Mohd , Zakaria Zunita , Mayaki Abubakar Musa
Published: May 2021

Background and Aim: Horse wounds can be easily infected with bacteria depending on the nature of its cause such as laceration, abrasion, or puncture as well as the nature of its environment. Various treatments are available in managing open wounds, including the usage of topical antibiotics and antiseptics. However, antibiotic resistance has been a major concern attributed with chronic wound infection. The aim of this study was to test the efficacy of ionized water at different pH against the growth of common bacteria from horse wounds.

Materials and Methods: Ten swab samples from equine infected wounds were collected and bacteria isolation and identification were performed. The antibacterial effect of the ionized water of pH 2.5, 4.5, 7.0, and 11.5 was tested on Staphylococcus aureus, Staphylococcus pseudintermedius, Staphylococcus intermedius, Escherichia coli, Pantoea agglomerans, and Klebsiella pneumoniae. The time-kill profiles of the ionized waters were determined at time 0, 2, 4, 6, and 8 h.

Results: Ionized water of pH 2.5 and 4.5 showed antibacterial activity against S. aureus, S. pseudintermedius, and S. intermedius with significant (p>0.05) reduction in colony-forming unit/mL within 2-8 h. The degree of bactericidal effect of the acidic ionized water differs between the species with S. intermedius more susceptible. However, there was no antibacterial effect at pH 2.5, 4.5, 7.0, and 11.5 on the Gram-negative bacteria tested.

Conclusion: Ionized water of pH 2.5 and 4.5 is effective in minimizing the growth of Gram-positive bacteria; thus it could be of clinical importance as an antiseptic for surface wound lavage in horses.
Un cuarto impropio: miedo y extranjería en La habitación alemana de Carla Maliandi
Authors: Seifert Marcos
Published: May 2021

La narradora y protagonista de La habitación alemana (2017) de Carla Maliandi viaja a la ciudad alemana de Heidelberg con el propósito de alejarse de los conflictos de su vida en Buenos Aires. La elección de esa ciudad no es azarosa: es el lugar donde pasó sus primeros cinco años de vida cuando sus padres se exiliaron en los años setenta. La narración se concentra en ese período de permanencia en la ciudad que constituye una suerte de fuga, pero también de retorno: un escape respecto de las responsabilidades y de la vida cotidiana que la aguarda en Buenos Aires, pero también un regreso imposible al espacio de la infancia. El desplazamiento se vuelve una forma de acceso a la comprensión de una potencia idealizante asociada a esa ciudad de su recuerdo infantil. Un «cuento de hadas» en el centro de la intimidad que se vuelve fuerza ficcional para repensar el hogar y lo propio. La narradora dará cuenta de la extranjería de los otros en un pasaje narrativo que se presenta como una oscilación del miedo hacia la perplejidad.
Café Müller y La consagración de la primavera en tensión
Authors: Hlebovich Ludmila
Published: May 2021

Café Müller y La consagración de la primavera conforman dos obras del Tanztheater Wuppertal, creado por Pina Bausch, que suelen presentarse juntas en una única función. Es posible notar que esta conjunción no se organiza tanto por lo que tienen en común como por aquello que las diferencia y tensiona. En este artículo propongo analizar dichas tensiones desde el pensamiento de Walter Benjamin teniendo en consideración que ambos autores, apoyados en el teatro brechtiano, apuntan a deshacer la ilusión frente a la crisis de la experiencia y de la narración. A través de la interrupción y la fragmentación toman distancia del expresionismo y del intento de recuperar una experiencia perdida resguardada en la interioridad. Cabe entonces la pregunta por si es posible un modo de experiencia y de narración sin continuidad. Desde aquí propongo comprender las distintas operaciones que forjan un modo urbano de narración en la obra de Bausch en relación con la situación de la experiencia en los espacios citadinos. Asimismo, teniendo en cuenta que tradicionalmente la filosofía ha desatendido a la danza, este recorrido permite poner de relieve y realizar una lectura de algunas de las esporádicas referencias de Benjamin a dicha forma del arte.
Habitar los durantes: procesos creativos en el estudio de reescrituras en la dramaturgia contemporánea
Authors: Sena Leticia Paz
Published: May 2021

Investigar la dramaturgia contemporánea implica abordar la complejidad de escribir en/para la escena. La dramaturgia es una práctica específicamente teatral en la que la palabra está involucrada con las materialidades y temporalidades de la escena. En este marco, el estudio puntual de las prácticas reescriturales añade otras complejidades: el gesto de volver a escribir lo que ya ha sido escrito es de apropiación y recontextualización, lo que lleva a cuestionarse qué es la escritura, qué es la autoría, qué es el tiempo. A la vez, las prácticas artísticas del presente asumen su carácter político en la preocupación por los modos de crear, lo que trae para la investigación la necesidad metodológica de atender a los procesos creativos y no solo a las obras como productos o resultados.

En este trabajo nos proponemos aproximarnos al proceso creativo de Edipo R. —obra teatral de Organización Q, estrenada en Córdoba en 2008 y dirigida por Luciano Delprato— y nos interesa entender esta reescritura de Edipo Rey, de Sófocles, como un devenir‒menor, en términos de Deleuze y Guattari.

Politeness strategies are known through translation techniques that are used in the novel translation. By analyzing data, it showed that the politeness strategies used in ordering speech act are bald on record, positive politeness, negative politeness, and off record. Based on the data, translation qualities of ordering speech sentences in the novel translation have shifted because of the use of politeness strategies. Furthermore bald on record is more shifted than other because it is shifting into positive politeness. So it can be concluded that the politeness strategies have changed the meaning of ordering speech on source language in English as asking speech on target language in Indonesian.

This article focuses on the smart approach applied in teaching two topics (referred to as learning contents) within English for Specific Purposes with regard to students’ motivation types. It introduces results of the research conducted in this field. The research is based on the definition of the term smart set by Silverio-Fernandez et al. (2018) and the theory of motivation types created by Plaminek (2010), who designed the standardised Motivation Type Inventory distinguishing four motivation types (accurators, coordinators, directors, explorers). Data were collected via didactic tests; quantitative methods were applied to calculate the potential increase in students’ knowledge as a difference between pre-test and post-test scores in the didactic tests. In total, 119 prospective teachers from the Faculty of Education and the Faculty of Science at Jan Evangelista Purkyne University participated in this research conducted via quasi-experimental ex-post-facto method for 12 weeks. The smart approach included the exploitation of smart devices and technologies (applications) in face-to-face instruction and in-home preparation for lessons. Three main hypotheses were set to prove whether the smart approach to ESP instruction can be applied to learners of all motivation types. According to the findings, the smart approach suited students of all motivation types; however, coordinators’ increase in knowledge was significantly higher compared to explorers and directors in one of the learning contents.

Le répertoire des tests de diagnostic disponibles du coronavirus du syndrome respiratoire aigu sévère 2 (SRAS-CoV-2) évolue rapidement. Bien que les tests sérologiques aient une capacité de diagnostic limitée concernant l’infection aiguë, leur rôle dans les études épidémiologiques et dans la prise de décision en santé publique ainsi que pour l’émission de recommandations est de plus en plus important. Compte tenu de la disponibilité mondiale de vaccins, les laboratoires cliniques sont de plus en plus sollicités pour assurer le dépistage des anticorps et l’interprétation des résultats pour les personnes vaccinées et non vaccinées. Nous présentons ici les données les plus récentes sur les délais de production des anticorps contre le SRAS-CoV-2, notamment la longévité des anticorps, ainsi que la production et la détection des anticorps neutralisants. En outre, nous formulons des conseils pratiques destinés aux laboratoires de microbiologie clinique afin que ces derniers vérifient les tests sérologiques commerciaux et choisissent les algorithmes de test appropriés pour leurs populations locales.
Examen déontologique des programmes d’immunisation de la santé publique au Canada
Authors: MacDonald Noni E , Harmon Shawn , Graham Janice E
Published: May 2021

L’Organisation mondiale de la Santé (OMS) reconnaît que la vaccination est l’une des interventions en matière de santé publique les plus efficaces pour sauver des vies. Lors de l’élaboration d’une feuille de route permettant d’établir un ordre de priorité relatif à l’utilisation des vaccins contre la maladie à coronavirus 2019 (COVID-19) dans un contexte d’approvisionnement limité, l’OMS a souligné l’importance d’un cadre de valeurs (principes éthiques). La vaccination doit faire l’objet d’un examen éthique indépendant des données de recherche sur les vaccins, des pratiques de fabrication, de l’assurance juridique et éthique du consentement éclairé, ainsi que des questions de justice sociale concernant l’équité des programmes, y compris le droit d’accès. Un examen déontologique du programme de vaccination de l’Australie a été rapporté en 2012. Ce dossier CANVax (Centre canadien de ressources et d’échange sur les données probantes en vaccination) propose un examen déontologique de la vaccination au Canada en utilisant les critères utilisés pour l’Australie.

“The Mirror Crack’d”: Representation of Characters in Terry Pratchett’s Witches Abroad
Authors: Mussa Jumana
Published: May 2021

The current article presents a discussion of two characters in Terry Pratchett’s Witches Abroad (1990), Esmeralda and Lily Weatherwax. These two sisters are almost mirror images of each other, yet each takes a different path in life. Through their similarities and differences, one is able to examine the idea of uncanny repetition, as it was discussed by Jacques Derrida and Gilles Deleuze. Through the characters’ choices and interaction with each other, one may also be able to explore their identities, as imperfect mirror reflections that contradict and inform each other.
The evolution of feminist literature in the Arab world
Authors: Khatib Gaida
Published: May 2021

In this article, we try to discuss the concept of the term “feminine literature” and the problems related to that in both Western and Arab worlds, with a historical overview of the evolution of Arab feminist literature from the pre-Islamic era to the present day. Besides that, we will relate to the difference between the writing of man and woman, as woman was distinguished by her own style as well as the issues she raises. However, despite the efforts, there has been a clear marginalization of woman’s writing, and there was no clear definition of the term.
AAAprawda. Telemetria prawdy
Authors: Michaluk Tomasz
Published: May 2021

Developed societies are not interested in the truth. The demand for truth has disappeared while its causal role has been marginalized and limited to the authentication of identity in banking systems and social media. Exactly a century earlier, due to due to fallibilism or falsificationism, science rejected the Cartesian conception of Absolute truth, while retaining its objectivity although not the stability of its findings. Today, we intersecting worlds, but not identical in values. The reason for this is not the inability to work out a common research method but an axiological redefinition, which often comes down to the question: truth and so what?
Techniczna konstrukcja/odkrywanie prawd (2): martyngał Kartezjusza i miary SI (metr)
Authors: Chwałczyk Franciszek
Published: May 2021

This is the second part of the two-part text based on the works of Martin Hei-degger, Lewis Mumford and Michel Serres. In the first part I analyzed the foundations or the birth itself (the Thales’ discovery – Serres, the ancient myth of the machine – Mumford) of a certain way of producing truths or conditions for recognizing something as true (the Truth). Here, in the second part, I show the discovery of how this Truth works and its development (the Descartes’ discovery, the modern myth of the machine), and thus a significant increase in the ability to produce truths. Continuing recognition made in the first part that – the figure of the essence of technology can be identified with figure of the Truth in this text and that its essence has been a ge-stell – I indicate martingale (Serres) and the myth of balance (Mumford) as ge-stell counterparts. A practical example on which I test the content of both parts of this text are Witold Kula’s research on old measures (part 1) and those from the SI system (in this part).

Filozofia XVII wieku – wielkie osobowości
Probabilistic kingdom – problem of objectivity in contemporary science
Authors: Pruski Paweł
Published: May 2021

Within the world of modern scientific theories, probability theory is one of the basic tools with which hypotheses are constructed. Scientists using probability theory often rely on its objective interpretation. In practice, this means that probability assertions should be independent of the beliefs of the individual. Accordingly, the following question arises: what do the contents of scientific assertions based on an objective interpretation of probability theory refer to? To answer that question, the author analyzes objective probability in the context of the scientific debate on determinism, addressing two types of arguments. On the one hand, a position will be examined according to which the only viable plane allowing for objective probability is indeterministic. Subsequently, the discussion will focus on arguments to the contrary, which presume coexistence of objective probability and determinism. The aim of this paper is to answer the question concerning the meaning of a sentence referring to the objective interpretation of probability, and aim to resolve whether it is in the context of either deterministic or indeterministic plane that one can speak of objective probability. As a result, the following thesis will be advanced: both the acceptance of a deterministic and an indeterministic plane as possible areas where objective probability can occur is extremely problematic. Depending on the chosen area, different types of problems arise, whose common denominator is misunderstood objectification. Consequently, the postulated objectivity of probability (and pertinent assumptions) can be reduced to the epistemic variant.
Sources of the Possibility of the Contemporary turn towards Religion
Authors: Torzewski Antoni
Published: May 2021

The return of religion in the philosophical reflection can be observed in the contemporary world. Thinkers like Richard Rorty, Gianni Vattimo or Charles Taylor can substantially exemplify that phenomenon. In this paper, we would like to focus on some of the aspects of modern and contemporary philosophy of religion and also on the sources that made it even possible. That is why at first we point out three critiques of religion present mostly in the XVIII-th and XIX-th century. Then we will inquire about the two main ways of understanding religion in the contemporary philosophy and about it’s source.
