Noise and signal as ground and figure: Emergence and interference in media ecologies
Authors: Castro Vinícius Portella 
Published: June 2022

AbstractThis paper proposes an interdisciplinary and generative understanding of noise that can be useful for thinking critically about art across different media ecologies. This notion of noise would be the counterpart of an intensive concept of information, such as the one presented by Gilbert Simondon. Unfolding a remark made by that author, the paper proposes three distinct notions of noise, as correlated to “pure chance”, “form”, and “information”. The noise of “pure chance” describes events of chaotic disruption and interference. The noise of “form” describes an index of the materiality and historical contingency of any transmission. The noise of “information” describes the irreducible margin of indeterminacy that is present at every layer of informational transmission and reception. An artwork created by Nam-June Paik is taken as a concrete demonstration of these three different kinds of noise. More generally, following sound theorist Aden Evens, an argument will be made for a speculative understanding of the signal in artistic practices as an emergent configuration from a ground of noise. To expand this idea for all media, we will explore the figure–ground relationship in the philosophy of Simondon as a scheme for the generation of forms from latent structural potential in a field. The work of Cécile Malaspina is used throughout the paper to clarify some confusions around the concept of noise and lay down the groundwork for fertile and rigorous interdisciplinary research across different media. The ambiguity of the concept of noise should not let us turn it into a night where all cows turn to greyscale. Instead, we should regard noise, in its distinct modes, as a marker of the granularity, speed, and resolution of any actual transmission and reception of information.

AbstractPatient-centred medicine is a healthcare approach that focuses on patients’ wants, needs and preferences. An obstacle to implement patient-centred medicine is the difficulty of obtaining data that is relevant and representative of the whole society. In 2019, the Spanish Society of Cardiology highlighted eight trends that would exert a determining influence on the future of cardiology: “demographics”, “economic environment”, “political environment”, “citizens’ expectations”, “incorporation of women”, “technological innovation”, “health levels and cardiovascular risk factors” and “healthcare organisation and management”. In order to assess these trends from a pacient-centred approach, the aim of this study is to evaluate the opinions of the individuals who are part of Spanish society, regarding the eight trends identified by the Spanish Society of Cardiology, using natural language processing tools to analyse the communications expressed by citizens in digital ecosystems and official channels of communication. We analysed communications published between 2007 and 2019. Natural language processing identified 17 areas of opinion that support the eight trends. We evaluated the impact of each area of opinion based on the standard metrics of online reputation: presence, emotion and reach. Thus, 257,456 communications were analysed. The most relevant trend was “healthcare organisation and management” (54% of the total impact), followed by “health levels and cardiovascular risk factors” and “demographics” (14% and 10%, respectively). The least relevant trend was “citizens’ expectations” (1%). Within the areas of opinion identified, the one with greatest impact was “the cardiologist” (16% of the total impact). In conclusion, the results of this research show that natural language processing tools are a useful tool for patient-centred medicine. The high impact associated with the cardiologist’s role, together with the low impact observed for “citizen’s expectations” show that Spanish citizens identify the cardiologist as the leading figure regarding their cardiovascular health.

Published: June 2022

We report on a multi-photon source based on active demultiplexing of single photons emitted from a resonantly excited GaAs quantum dot. Active temporal-to-spatial mode demultiplexing is implemented via resonantly enhanced free-space electro-optic modulators, making it possible to route individual photons at high switching rates of 38 MHz. We demonstrate routing into four spatial modes with a high end-to-end efficiency of ≈  79% and measure a four-photon coincidence rate of 0.17 Hz mostly limited by the single-photon source brightness and not by the efficiency of the demultiplexer itself. We use the demultiplexer to characterize the pairwise indistinguishability of consecutively emitted photons from the quantum dot with variable delay time.

Published: June 2022

In recent years, the field of flexible electronics has become one of the cross-disciplinary research hotspots, attracting worldwide attention and making rapid advances. So far, there has been plenty of research on the use of two-dimensional (2D) materials in flexible electronics, including graphene, transition metal dichalcogenide, and so on. In this work, we successfully prepared quasi-one-dimensional (Q1D) Nb2Pd0.73S5.97 superconductors on flexible paper by mechanical friction and systematically studied their physical properties at low temperatures. Superconductivity with transition temperature (Tc) ∼ 6.05 K by Meissner effect was observed in Nb2Pd0.73S5.97 wires coated on flexible paper, and a resistance drop at 4.80 K was confirmed in electrical transport measurements. The lower critical field (Hc1) of coated paper shows anisotropy effect under parallel and perpendicular magnetic fields, exhibiting a 2D-like feature, unlike the bulk Nb2Pd0.73S5.97 fibers. Our work provides a broader platform for the application of low-dimensional materials in flexible functional devices.

Published: June 2022

Background Medicare, the health insurance system underpinning free healthcare in Australia, introduced free telehealth items in 2020 in response to the coronavirus disease 2019 (COVID-19) pandemic. Their uptake among healthcare providers was significant, including among general practitioners and sexual health services. Here, we report people’s experiences of accessing sexual and reproductive health (SRH)-related care via telehealth collected as part of a survey exploring the impact of COVID on SRH health. Methods This study utilises qualitative data from two online surveys conducted in 2020. Surveys were advertised through social media and professional and personal networks. Anyone aged ≥18 years and living in Australia was eligible to participate. Respondents were asked whether they accessed care for their SRH via telehealth. A free-text question asking for further detail about their experience was analysed using content analysis. Results A total of 114/1070 respondents (10.7%) accessed healthcare services via telehealth for SRH-related reasons within the previous 4 weeks. Three themes were identified from 78 free-text comments: (1) accessibility and convenience of telehealth; (2) appropriateness of telehealth for SRH issues; and (3) connecting and communicating with clinicians via telehealth. Respondents had a wide range of experiences. Telehealth improved access to services for some participants, and it was appropriate for some, but not all SRH issues. Difficulties connecting with clinicians on both an interpersonal and technical level was a key barrier to a satisfactory patient experience. Conclusions Telehealth can offer a viable alternative to face-to-face care, providing patients can overcome key connection and communication barriers.
A study of linguistic manipulations of activating, seeking and creating common ground in intercultural business communication
Authors: Li Chengtuan 
Published: June 2022

Abstract
Previous studies on common ground (CG, for short) have mainly focused on its definition and functions in various daily interactions. Few studies explore the linguistic manipulations of CG in cross-cultural business interactions. This paper aims to fill in this gap by examining how sellers and buyers manipulate linguistic actions of activating, seeking and creating CG to make a deal. This study instantiates and develops Kecskes’ (2013) CG model. Based on qualitative analysis of data collected from email interactions between Chinese sellers and Australian buyers, I find that (1) Interlocutors often activate their core CG through manipulating frequency markers such as “again”, and epistemic markers such as “I knew”, “you know”, “might”; (2) Interlocutors seek core CG and emergent CG by manipulating epistemic markers such as “I’m sure”; (3) Interlocutors often bring the third party or element into the communication to create emergent CG by using question markers such as “you see?”, imperative markers such as “Do you understand!”, and narrative markers like “I tell you” and “once” or “before”; (4) The interpersonal manipulations of CG construction contribute to business integrity and reliability because the more efforts interlocutors make to activate, seek, and create CG, the more clarified and acceptable their business relations become in business communication. For the purpose of validating what I have found, I conduct a quantitative study of linguistic means of constructing CG in the Santa Barbara Corpus of Spoken American English (SBCSAE), and summarize the typical linguistic means of activating, seeking, and creating CG in various settings.
Investigation on rheological characteristics of magnetorheological shear thickening fluids mixed with micro CBN abrasive particles

Published: June 2022

Abstract
The novel magnetorheological shear thickening polishing fluids (MRSTPFs) were developed by mixing micro cubic boron nitride (CBN) abrasive particles into traditional magnetorheological shear thickening fluids. MRSTPFs were constructed by uniformly fumed silica and polyethylene glycol as shear thickening fluids, carbonyl iron particles (CIPs) as ferromagnetic phase and CBN particles as abrasive phase. In this work, various MRSTPFs were prepared to explore their rheological characteristics. Sweeps of steady shear rate and dynamic shear frequency were conducted under different magnetic flux densities, respectively. A mathematical model was presented to explain shear rate variation with shear stress. The magnetorheological shear thickening mechanism was well described. The rheological experiment results have revealed that shear thickening effect was still existing in magnetic flux density. However, the increased magnetic flux density played a negative role on the shear thickening effect. Particle size optimization of CIPs was thus essential to maximize the shear thickening effect. On the other hand, with increased shear frequency, the viscoelastic feature of MRSTPFs was converted from linear to non-linear. It was found that the shear yield stress of the MRSTPFs was magnified with the stronger magnetic flux density and larger CIPs size. The investigation of rheological characteristics demonstrated that MRSTPFs could enhance polishing performance, which contributed to developing a high-efficiency and ultra-precision polishing process.

Published: June 2022

Abstract

Objective. We investigated whether a recently introduced transfer-learning technique based on meta-learning could improve the performance of brain–computer interfaces (BCIs) for decision-confidence prediction with respect to more traditional machine learning methods. Approach. We adapted the meta-learning by biased regularisation algorithm to the problem of predicting decision confidence from electroencephalography (EEG) and electro-oculogram (EOG) data on a decision-by-decision basis in a difficult target discrimination task based on video feeds. The method exploits previous participants’ data to produce a prediction algorithm that is then quickly tuned to new participants. We compared it with with the traditional single-subject training almost universally adopted in BCIs, a state-of-the-art transfer learning technique called domain adversarial neural networks, a transfer-learning adaptation of a zero-training method we used recently for a similar task, and with a simple baseline algorithm. Main results. The meta-learning approach was significantly better than other approaches in most conditions, and much better in situations where limited data from a new participant are available for training/tuning. Meta-learning by biased regularisation allowed our BCI to seamlessly integrate information from past participants with data from a specific user to produce high-performance predictors. Its robustness in the presence of small training sets is a real-plus in BCI applications, as new users need to train the BCI for a much shorter period. Significance. Due to the variability and noise of EEG/EOG data, BCIs need to be normally trained with data from a specific participant. This work shows that even better performance can be obtained using our version of meta-learning by biased regularisation.
Persistence probabilities of mixed FBM and other mixed processes
Authors: Aurzada Frank , Kilian Martin , Sönmez Ercan 
Published: June 2022

Abstract
We consider the sum of two self-similar centred Gaussian processes with different self-similarity indices. Under the assumption of non-negative correlations and some further minor conditions, we show that the asymptotic behaviour of the persistence probability of the sum is the same as for the process with the greater self-similarity index. In particular, this covers the mixed fractional Brownian motion introduced in (Cheridito 2001 Bernoulli
7 913–34) and shows that the corresponding persistence probability decays asymptotically polynomially with persistence exponent 1 − max(1/2, H), where H is the Hurst parameter of the underlying fractional Brownian motion.

Published: June 2022

Abstract
This investigation aimed to determine the physicochemical, proximate, and antioxidant results of a functional drink made from red and purple roselle with the addition of chitosan. Six drink formulations were prepared based on different ratios for red, purple roselle extracts and chitosan, respectively; C0 (30: 0: 0)%; C1 (0: 30: 0)%; F1 (20: 10: 0.5)%, F2 (10: 20: 0.5)%, F3 (20: 10: 1)%, and F4 (10: 20: 1)%. Functional drink samples were made by the pasteurization method at 90 °C for 15 minutes. The scavenging activity of 2,2-diphenyl-1-picrylhydrazyl (DPPH) was used to measure antioxidant activity. The resulting pH values ranging from 2.62 to 3.20. Moisture content ranging from 90.45 to 93.10 g/100 ml, ash content ranging from 2.20 to 3.44 g/100 ml, protein content ranging from 1.42 to 2.62 g/100 ml, fat content ranging from 0.22 to 0.48 g/100 ml. The scavenging ability on DPPH radical is the highest on F4 with the addition of 1% chitosan ranging from 18.08% to 34.10% and the smallest at C0 is 10.05% to 27.15%. The results show that the addition of chitosan can improve the physicochemical, proximate, and antioxidant properties in functional drinks from red and purple roselle extracts.

Abstract
Bio oil is the result of pyrolysis of biomass raw materials in the form of dark-colored liquids containing major chemical compounds such as benzene compounds, aromatic compounds, aliphatic, and other organic compounds. In the future, bio-oil is expected to be a substitute for fossil fuels as they are more environmentally friendly. Empty fruit bunches (EFB) from oil palm are one type of biomass that can be used as bio-oil products. The elements of pyrolysis that were analyzed were High Heating Value (MJ/kg), pH, viscosity, density and analysis of the components of hydrocarbon compounds formed using GCMS analysis. The results showed that HHV value 35.66 MJ / - 39.09 MJ/kg, the pH value of bio-oil was somewhat similar to normal pH 4 - 6, and viscosity was 4 - 9 cp. The results of GCMS analysis showed that the content of the optimal percentage of hydrocarbon compounds was treated with 40 mesh powders with a hydrogen pressure of 15 bar. 19 types of hydrocarbon compounds were found with a total percentage of 13.79 %.

Abstract
Vannamei shrimp (Litopenaeus vannamei) is one of the perishable foodstuffs. Therefore, we need a good supply chain system so that vannamei shrimp can reach consumers while maintaining quality. This study aims to analyze the efficiency of supply chain performance at PT Sari Indonesia Group. The method used to measure the efficiency of supply chain performance is the Supply Chain Operation Reference (SCOR) method, starting with creating an initial hierarchy in the SCOR process (Plan, Source, Make, Delivery, and Return). The dimensions used are Reliability, Responsiveness, Flexibility, Cost, and Asset. The Analytical Hierarchy Process (AHP) and Objective Matrix (OMAX) methods were used to measure the supply chain performance efficiency. The results of this study indicated that the efficiency of supply chain performance at UD. Sari Inti Tani was in the GOOD category with a total index of 7,03. There are three categories included in the Red Zone, which the company must review immediately: the time to identify (check) employee performance, production quantities, and production costs.

AbstractThis study aimed to examine the effect of supplementation on Moringa leaf meal and palm oil on the dry matter (DM), crude protein (CP) and water consumption in sheep. The material research used 18 thin tailed of 8-month-old sheep. The supplementation feed used was Moringa leaf flour and palm oil. The design used in this study was a Completely Randomized Design (CRD) with 3 treatments and 6 replications. The treatments include: P0: basal feed; P1: P0 + 2% Moringa leaf meal; P2: P1 + 0.5% palm oil. The variables measured were dry matter (DM), crude protein (CP) and water consumption. Data were analyzed by Analysis of Variance (ANOVA). The results of the analysis of variance showed that the treatment had no significant effect on dry matter (DM) and water consumption but had a significantly effect on crude protein consumption (CPI). The results showed that the dry matter consumption (DMI) of each treatment were P0 (control): 615.95 ± 98.50 g / head / day; P1: 728.37 ± 75.16 g / head / day; and P2: 616.62 ± 99.37 g / head / day. Crude protein consumption (CPI) from each treatment were P0 (control): 80.28 ± 12.84 g / head / day; P1: 122.55 ± 12.65 g / head / day; and P2: 93.64 ± 15.09 g / head / day. Water consumption from each treatment were P0 (control): 1535.67 ± 798.01 ml / head / day; P1: 1572.17 ± 855.73 ml / head / day; and P2: 1512.50 ± 532.67 ml / head / day. Based on the research results, concluded that the use of 2% Moringa leaf meal in silage-based feed supplementation increases the crude protein consumption (CPI).

Abstract
Development of ruminant livestock requires to a stable availability of feed because feed is a determining factor for the continuity and success of businesses in livestock production The aimed of this study was to analyses the potential for beef cattle development based on the availability of forage from agricultural waste in the eastern region of West Java province. The sample locations were taken from 3 regencies based on low of population density per unit of agricultural land, namely Majalengka, Indramayu, and Ciamis Regency. Time series data on land use and agricultural waste production at the Regency’s from 2015 to 2019 were used in this research. Data analysis used LQ (location question) and IDD (carrying capacity index). The results showed that the total sub-Regency’s from 3 Regency’s was 84 sub-districts, where there were 24 sub-districts that have LQ> 1, indicates that these sub- districts were the base area for beef cattle development. Furthermore, based on the IDD analysis, all of the 24 sub-districts have IDD values > 2, which means that based on the availability of forage from agricultural land, it was in the safe category to increase of the beef cattle population. The twenty-four sub-districts in West Java Province can serve as the basis for the development of beef cattle that need to be considered by farmers and the local government, namely increasing production (especially quality forage feed even though the availability of agricultural waste is sufficient), productivity and efficiency (marketing infrastructure) supported with policy government.
