Dynamic kernel matching for non-conforming data: A case study of T cell receptor datasets
Authors: Ostmeyer Jared , Cowell Lindsay , Christley Scott
Published: March 2023

Most statistical classifiers are designed to find patterns in data where numbers fit into rows and columns, like in a spreadsheet, but many kinds of data do not conform to this structure. To uncover patterns in non-conforming data, we describe an approach for modifying established statistical classifiers to handle non-conforming data, which we call dynamic kernel matching (DKM). As examples of non-conforming data, we consider (i) a dataset of T-cell receptor (TCR) sequences labelled by disease antigen and (ii) a dataset of sequenced TCR repertoires labelled by patient cytomegalovirus (CMV) serostatus, anticipating that both datasets contain signatures for diagnosing disease. We successfully fit statistical classifiers augmented with DKM to both datasets and report the performance on holdout data using standard metrics and metrics allowing for indeterminant diagnoses. Finally, we identify the patterns used by our statistical classifiers to generate predictions and show that these patterns agree with observations from experimental studies.
Can individual subjective confidence in training questions predict group performance in test questions?
Authors: Shirasuna Masaru , Honda Hidehito
Published: March 2023

When people have to solve many tasks, they can aggregate diverse individuals’ judgments using the majority rule, which often improves the accuracy of judgments (wisdom of crowds). When aggregating judgments, individuals’ subjective confidence is a useful cue for deciding which judgments to accept. However, can confidence in one task set predict performance not only in the same task set, but also in another? We examined this issue through computer simulations using behavioral data obtained from binary-choice experimental tasks. In our simulations, we developed a “training-test” approach: We split the questions used in the behavioral experiments into “training questions” (as questions to identify individuals’ confidence levels) and “test questions” (as questions to be solved), similar to the cross-validation method in machine learning. We found that (i) through analyses of behavioral data, confidence in a certain question could predict accuracy in the same question, but not always well in another question. (ii) Through a computer simulation for the accordance of two individuals’ judgments, individuals with high confidence in one training question tended to make less diverse judgments in other test questions. (iii) Through a computer simulation of group judgments, the groups constructed from individuals with high confidence in the training question(s) generally performed well; however, their performance sometimes largely decreased in the test questions especially when only one training question was available. These results suggest that when situations are highly uncertain, an effective strategy is to aggregate various individuals regardless of confidence levels in the training questions to avoid decreasing the group accuracy in test questions. We believe that our simulations, which follow a “training-test” approach, provide practical implications in terms of retaining groups’ ability to solve many tasks.

Phenology studies the time at which events in the life cycle of a species occur sand how they are related to environmental cues. Patterns of change in phenology at different scales can be used as an indicator of ecosystem changes and climate change, but the data necessary to detect these changes can be difficult to obtain due to their temporal and regional dimensions. Citizen science can contribute to generate large amounts of data on phenological changes at wide geographical scales that would be almost impossible for professional scientists to generate, but the quality and reliability of these data are often questioned. The objective of this study was to evaluate the use of a biodiversity observation citizen science platform based on photographic information as a potential source of large-scale phenological information, and to identify the key benefits and limitations of this type of information source. We used the Naturalista photographic databases for two invasive species in a tropical region:Leonotis nepetifoliaandNicotiana glauca. The photographs were classified into different phenophases (initial growth, immature flower, mature flower, dry fruit) by three groups of volunteers: a group of experts, a trained group with information on the biology and phenology of both species, and an untrained group. The degree of reliability of the phenological classifications was estimated for each group of volunteers and each phenophase. The degree of reliability of the phenological classification of the untrained group was generally very low for all phenophases. The group of trained volunteers showed accuracy levels for the reproductive phenophases that equaled the degree of reliability among the expert group, regardless of species, and was consistent across phenophases. We conclude that volunteer classification of photographic information contained in biodiversity observation platforms can provide phenological information with high geographic coverage and an increasing temporal coverage on general phenological patterns of species with wide distributions but has limited applicability in the identification of exact start and end dates. and peaks of the different phenophases.

Intercultural dialogue in manga: Building friendships, sharing spaces and values
Authors: Perry Melissa Shamini , M. M. Raihanah , Mohd Lazim Zalina
Published: March 2023

Manga as a cultural art form delves into various sociocultural issues and narratives, and the representation of diverse cultural contexts in manga has increased over the years. The role of Japanese manga as a site for intercultural understanding and engagement is worth further investigation, and research in this area is still growing. This article explores intercultural dialogue through a case study of the Japanese manga Satoko and Nada Volume 1 by Yupechika, which narrates the friendship between Satoko, a young Japanese woman, and Nada, her Saudi Muslim roommate. It adopts a literary approach to the analysis of the manga and employs textual analysis as the methodology. The manga is analysed through the lens of interculturalism and deep dialogue focusing on the themes of food, fashion and faith. Through the analysis, readers are exposed to the narrative of intercultural engagement as portrayed by the mangaka. Yupechika incorporates pre-existing prejudices in the engagement between the two culturally diverse characters. The narrative arc reveals the importance of empathy, space and value sharing in forging intercultural understanding. This reading into Yupechika’s intercultural narrative is a microcosm of the type of dialogue needed in the world today to overcome the acute racism and xenophobia.

Published: March 2023

Context: Self-sovereign identity (SSI) enables the creation of user-centric, privacy-by-design, secure, and decentralized identity-management systems. The aim of this paper is to carry out a bibliometric analysis of the scientific production on SSI during the period 2017-2022.Method: A complete bibliometric analysis of all publications on SSI indexed in Scopus and Web of Science was carried out. A corpus of 143 articles was examined by processing their bibliographic metadata on a bibliometric tool. In order to do this, the Bibliometrix packageand the R programming language were used.Results: A bibliometric characterization of the publications on SSI was obtained for the 2017 − 2022 period. The most important keywords used in these publications were identified, as well as their use tendencies throughout this period. Moreover, the most influential authors in the area and the most relevant publication sources were also identified.Conclusions: The results of the bibliometric analysis show that Lotka’s and Bradford’s laws apply for academic publications on SSI, which means that the most relevant publications in this area are concentrated in a relatively small group of authors and journals. Paul Jenkins, Nitin Naik, Yang Liu and Aijun An were the most impactful authors, and Lecture notes in computer science, Frontiers in blockchain and IEEE were the most influential journals. Finally, the keyword analysis showed that Blockchain, Authentication, Identity management, Electronic document identification systems, and Digital identity are currently the most relevant concepts for SSI.

Published: March 2023

Preclinical research remains the essential platform in the development and optimization of medical therapies and advancements in translational medicines. However, specifically to animal research, federal laws, and institutional policies require investigators to apply the principles of the 3R's (replacement, reduction, and refinement). The concept of benchtop models utilizing isolated organs, in which multiple variables can be controlled to recreate human function, has been innovative advancements in preclinical research models that adhere to these principles. More specifically, isolated perfused kidney (IPK) models have been invaluable preclinical tools that have led to numerous advancements over the decades, including understanding renal physiology, pharmacologic therapies, and improvements in renal transplantation. However, pre‐existing IPK models are not without their own limitations, leaving areas for improvement. An isolated perfused kidney apparatus was designed to best recreate human use conditions as a preclinical tool. Porcine renal blocks were chosen over the more commonly used rodent models, due to their greater similarities to human anatomies. Sixteen porcine kidney pairs obtained en bloc were extracted and placed onto an apparatus where aortic flows, pressures, and overall systemic temperatures were controlled. Organ viability was assessed in 10 renal blocks (n = 8 fresh and n = 2 previously frozen specimens) via both urinary flows and compositions at timepoints up to 180 min. Multimodality imaging, which included fluoroscopy, ultrasound, optical coherence tomography (OCT), and video scopes, was also employed to capture internal and external images to determine renal artery orientations and dimensions. Anatomical measurements and viability assessments of porcine renal blocks were successfully achieved in our perfusion model. Renal main artery diameters averaged smaller in our sample size than in human anatomy while also having more superior takeoff angles. Yet, the average lengths of each main segment were comparable to human anatomy: 32.09 ± 7.97 mm and 42.23 ± 7.33 mm in the left and right renal main artery, respectively. Urine production and urine composition of the fresh renal blocks, when compared to the frozen blocks and baseline perfusate, showed kidney viabilities of up to 3 h via excretion and retention of various metabolites. In this paper, we described a protocol for an isolated perfused kidney apparatus using large mammalian renal blocks. We believe this protocol to be an improvement from similar pre‐existing models in better representing human physiologic function while allowing for multimodal imaging. The resulting Visible Kidney™ preclinical model, which has shown viability after isolation and reperfusion, can be a fast and reliable tool for the development of medical devices while also reducing the unnecessary use of animals for research.

Published: March 2023

Primary thyroid adenoid cystic carcinoma (PTACC) is an extremely rare type of mucin-secreting adenocarcinoma. Currently, it is difficult to diagnose, and it lacks standard treatment protocols. We report the case of a 53-year-old female patient with PTACC who underwent additional intensity-modulated radiotherapy 1 month after surgical treatment with an uneventful course. No invasion or distant metastasis was detected at the 7-month follow-up after radiotherapy, and the prognosis was favorable. In this case, herein, we have summarized the diagnostic features of the disease and proposed that postoperative adjuvant radiotherapy can significantly improve the patient’s prognosis. Finally, we further confirmed the important role of radiotherapy in PTACC by reviewing relevant literature, which may provide clinicians with valuable treatment experience.
Ageing bodies and beauty in selected Polish women’s magazines
Authors: Kociołek Katarzyna
Published: March 2023

The aim of the article is to examine the representation of ageing in selected issues of the Polish women’s magazine Twój Styl. With reference to Wolf’s concept of the “beauty myth,” the article argues that ageing is presented as a threat to women’s psychological integrity. Although the theme of old age is rarely directly addressed in the magazines, its presence is implied in the advertised anti-age beauty products. Based on semiotic theory and Cognitive Metaphor Theory, the paper demonstrates that the advertising of anti-ageing beauty products serves the function of controlling ageing female bodies, which are positioned outside of the mainstream concept of femininity.
Paint Pigment on Epigraphic Squeezes: A Case-Study from the Etruscological Collections of Olof August Danielsson
Authors: Burman Annie
Published: March 2023

The practice of wet squeezing as a means of creating epigraphic facsimiles was widespread during the 19th and 20th centuries, but often negatively impacted the original inscriptions, particularly in cases where paint pigment was present. Depending on the precise method used, the pigment may transfer from the original to the squeeze. This article presents a case-study of four such squeezes made by Swedish Etruscologist Olof August Danielsson in 1886 of a funerary tile from Chiusi, as part of the preparatory work for Corpus Inscriptionum Etruscarum. This material makes it possible to study epigraphic polychromy in cases where pigment on the original has been damaged through squeezing. In addition, it illustrates how squeezes can give insight into the history of individual objects, as the squeezes, which show both the carving and the paint, cast light on the various proposed readings of the tile’s Etruscan inscription (CIE 1973/ET Cl 1.1478).
California Hospitals’ Rapidly Declining Traditional Medicare Operating Margins
Authors: Gaudette Étienne , Bhattacharya Jay
Published: March 2023

In recent years, Medicare margins of U.S. short-term acute care hospitals participating in the inpatient prospective payment system (IPPS) have declined nationally by over 10 percentage points, from 2.2% in 2002 to −8.7% in 2019. This trend conceals critical regional variations, with recent studies documenting particularly low and negative margins in metropolitan areas with higher labor costs despite geographic adjustments by the Centers for Medicare & Medicaid Services (CMS). In this article, we describe recent trends in California hospitals’ traditional fee-for-service Medicare operating margins compared to hospital operating margins across payers and changes in the CMS hospital wage index (HWI) used to adjust Medicare payments. We conduct an observational study of audited financial reports of IPPS-participating California hospitals using California Department of Health Care Access and Information and CMS data for years 2005–2020 (n = 4429 reports included in the analysis). We describe trends in financial measures by payer and investigate associations between HWI and traditional Medicare margins, focusing on the pre-COVID period of 2005 through 2019. During that period, California hospitals’ statewide traditional Medicare operating margin declined from −27 to −40%, and financial shortfalls in caring for fee-for-service Medicare patients more than doubled ($4.1 billion in 2005 to $8.5 billion in 2019, both values in 2019 dollars). Meanwhile, operating margins from commercial managed care patients increased from 21% in 2005 to 38% in 2019. There was a stable negative association between HWI and traditional Medicare operating margins throughout the period (p = 0.000 in 2005; p < 0.0001 in 2006–2020), indicating that areas of California with higher health care wages had persistently worse traditional Medicare operating margins than areas with lower wages.
Using imagery to build confidence in esports
Authors: Vealey Robin , Wright Emily
Published: March 2023

The purpose of this article is to provide strategies for using imagery to build confidence in esport athletes. Because confidence is a belief and strongly influenced by success and failure, mental training using imagery should be designed to create and sustain an agile mindset to accept events that shake confidence and enable athletes to respond productively to adapt and restore self-belief. Esport athletes should start small with short but frequent sessions of polysensory imagery practice of simple skills and strategies to build imagery skill and confidence. Imagery practice should be similar to competition, in terms of physical posture, setting, and equipment. Confidence-building imagery strategies include creating and rehearsing optimal performance plans as well creating imagery scripts for productive responses to mistakes, losing, tilting, and worrying about the skills and decision-making of teammates. Uses of imagery can be periodized to optimally develop confident performance and responses, prepare for specific opponents or tournaments, and assess prior performances using a growth mindset to enhance self-belief.
Temporally Local Maximum Likelihood with Application to SIS Model
Authors: Gourieroux Christian , Jasiak Joann
Published: March 2023

The parametric estimators applied by rolling are commonly used for the analysis of time series with nonlinear patterns, including time varying parameters and local trends. This paper examines the properties of rolling estimators in the class of temporally local maximum likelihood (TLML) estimators. We consider the TLML estimators of (a) constant parameters, (b) stochastic, stationary parameters and (c) parameters with the ultra-long run (ULR) dynamics bridging the gap between the constant and stochastic parameters. We show that the weights used in the TLML estimators have a strong impact on the inference. For illustration, we provide a simulation study of the epidemiological susceptible–infected–susceptible (SIS) model, which explores the finite sample performance of TLML estimators of a time varying contagion parameter.
Engineering isospectrality in multidimensional photonic systems
Authors: Lee Dayeong , Park Hyungchul , Yu Sunkyu
Published: March 2023

Selective manipulation of energy levels plays an essential role in realizing multichannel wave devices. One of the representative examples is to utilize the concept of quasi-isospectrality: a family of wave systems with an almost identical spectrum except for a part of energy levels. Most approaches toward quasi-isospectrality have employed analytical methods based on symmetry or tridiagonalization, such as supersymmetry, Householder, or Lanczos transformations. Although such analytical approaches provide deterministic and stable designs based on operator factorizations, the mathematical strictness in the factorizations, at the same time, hinders isospectral engineering in a given multidimension. Here we develop the semi-analytical method for engineering isospectrality in multidimensional photonic systems. The method provides the systematic perturbation for the target energy level shifts by decomposing the allowed form of system changes into the perturbation basis. We demonstrate the isospectrality of lower-, higher-, and random-order states while imposing the designed shifts on the other states. The stability analysis shows that the accuracy of the method is determined by the ranges of isospectral state numbers and perturbation strength. The systematic, free-form, and multidimensional natures of the proposed method show great potential for the platform-transparent design of multichannel devices.

Development of variotherm extrusion blow molding technology to produce high-gloss automotive spoilers
Authors: Xiao Cheng-Long , Hopmann Christian , Kahve Cemi E.
Published: March 2023

The surface quality of plastic parts produced by the conventional extrusion blow molding (EBM) process is usually poor, especially for those made of engineering thermoplastics. To achieve a high-gloss appearance, some costly and pollutive post-treatments (e.g., painting, polishing, etc.) have to be employed to hide or eliminate surface defects. Herein, a variable mold temperature EBM (i.e., variotherm EBM) technology with electric heating and water cooling, which has the potential to directly yield high-gloss parts, was developed. First, the process principle was designed and presented. Then, an complex industrial plastic part, i.e., automotive spoiler, was selected as a molding case to be studied, in which the variotherm blow mold of the spoiler was designed and especially the design rationality of the mold electric-heating and cooling systems was then examined by numerically evaluating the mold thermal response in the respect of cavity surface heating/cooling efficiencies and uniformity. Finally, the variotherm EBM experiments based on the manufactured prototype spoiler mold were conducted. The results showed that the developed technology can realize high-temperature blow molding with both the molding cycle time and energy consumption in an acceptable range compared with the conventional EBM. Moreover, the surface quality of the molded spoilers is largely improved and the surface defects that are generally appearing in the conventional EBM process can be fully eliminated. Thus, the feasibility and effectiveness of developed technology in yielding high-gloss blow-molded parts are demonstrated.
The Mobility of Neurofilaments in Mature Myelinated Axons of Adult Mice
Authors: Fenn J. Daniel , Li Yinyun , Julien Jean-Pierre , Jung Peter , Brown Anthony
Published: March 2023

Studies in cultured neurons have shown that neurofilaments are cargoes of axonal transport that move rapidly but intermittently along microtubule tracks. However, the extent to which axonal neurofilaments movein vivohas been controversial. Some researchers have proposed that most axonally transported neurofilaments are deposited into a persistently stationary network and that only a small proportion of axonal neurofilaments are transported in mature axons. Here we use the fluorescence photoactivation pulse-escape technique to test this hypothesis in intact peripheral nerves of adult malehThy1-paGFP-NFMmice, which express low levels of mouse neurofilament protein M tagged with photoactivatable GFP. Neurofilaments were photoactivated in short segments of large, myelinated axons, and the mobility of these fluorescently tagged polymers was determined by analyzing the kinetics of their departure. Our results show that >80% of the fluorescence departed the window within 3 h after activation, indicating a highly mobile neurofilament population. The movement was blocked by glycolytic inhibitors, confirming that it was an active transport process. Thus, we find no evidence for a substantial stationary neurofilament population. By extrapolation of the decay kinetics, we predict that 99% of the neurofilaments would have exited the activation window after 10 h. These data support a dynamic view of the neuronal cytoskeleton in which neurofilaments cycle repeatedly between moving and pausing states throughout their journey along the axon, even in mature myelinated axons. The filaments spend a large proportion of their time pausing, but on a timescale of hours, most of them move.
Global Black Cinema’s Personalized Archive
Authors: Muyumba Walton
Published: March 2023

This article examines the concentric resonances among Peck’s recent documentary, Exterminate All the Brutes, and his other films. Exterminate All the Brutes is an effort to make visible and audible the forgotten and unspeakable about the West: that its basic, winning practices are white supremacy, colonialism, and genocidal extermination. Peck’s new opus is a critical interrogation of the West and the Western cinematic and image archive. The film functions as both rebuke and “counter testimony,” building out in vision of a global black film archive. Ultimately, Peck’s four-part documentary encourages viewers to think through cinema about the West critically and models the use of documentary filmmaking as a practice of freedom.
EFFECTS OF INDIUM SLABS ON THE STRUCTURAL AND ELECTRICAL PROPERTIES OF STACKED LAYERS OF Cu2O
Authors:   Department of Physics, Arab American University, Jenin, Palestine, QASRAWI A. F. , OMAR A. ,   Department of Physics, Arab American University, Jenin, Palestine
Published: March 2023

In this work, the structural and electrical properties of stacked layers of Cu2O that comprises indium slabs in its structure are reported. The stacked layers which are coated onto glass and Au substrates under vacuum pressure of 10-5 mbar are characterized by the X-ray diffraction and impedance spectrometry techniques. While the Cu2O/Cu2O (CC) layers exhibited amorphous nature of growth, those which contained indium slabs (CIC) displayed weak crystallinity. The insertion of indium slabs between stacked layers of cuprous oxide highly increased the electrical resistivity and shifted the acceptor level closer to the valance band edge. In addition, the analyses of the conductance and capacitance spectra in the frequency domain of 0.01-1.0 GHz have shown that these two physical parameters are strongly affected by the insertion of indium slabs and by surface deformation effects. The capacitance spectra showed negative capacitance effect (NC) in all the studied frequency domain. The NC effects become less pronounced in the CIC samples owing to the changes in the polarization mechanism. The feature of NC effects make both of the CC and CIC samples more appropriate for electronic and telecommunication technology as it can be used in amplifiers to enhance he gain, as parasitic cancellers and as noise reducers.

In this study, two-step chemical bath deposition (CBD) technique has been employed for the fabrication of Zinc Oxide (ZnO) nanorods at low temperature. The ZnO nano-seed layer was deposited on the glass substrate using a radio frequency sputtering discharge technique. The impact of three zinc salts with Hexamethylenetetramine (HMTA) on the properties of ZnO nanorods have been investigated. The double beam UV visible (UV4100) spectrometer, micro-Raman scattering, and Field emission scanning electron microscopy (FESEM) were used to characterize and study the optical properties, energy band gap, defects, Raman spectra, phase orientation, quality of material, the interaction of phonons, transport properties, and the morphology of synthesized ZnO nanorods (NRs), respectively. The three zinc salts are Zinc Nitrate Hexahydrate, Zinc Acetate, and Zinc Chloride. The results found that the variation in zinc salts types with Hexamethylenetetramine as deposition solution is play a very important impact on the structures of fabricated ZnO nanorods that effected directly on the optical properties, energy band, material quality, and phase orientation of ZnO NRs. Also, from UV measurement the optical properties and energy band gap of produced ZnO nanorods are changed with changing the zinc salt as a precursor of deposition solution.

Lead Selenide Sulphide (PbSeS) nanomaterial, a chalcogenide semiconductor which has maximum radiation attenuation can be tuned for required wavelength in the range from ultraviolet to infrared. Hence it has received much interest among researchers. Further, the electronical and optical properties of PbSeS Quantum Dots were modeled by Brus Equation, Vegard’s law and Interpolation principle calculations. Therefore, in this paper, we have studied the progress and structural parameters of PbSeS at different energy band gap and wavelength. The obtained results confirms that the attenuation of radiation versus wavelength is inversely proportional to the bandgap and also the mole fraction of lead increases with decrease in energy band gap. These findings confirm the quantum effects of the material and which can be utilized in solar cell and optoelectronics applications. The results are compared with available experimental data that supports the validity of the model reported.

Al3Ni20Bx alloys (0.06≤ x ≤0.12) nanocrystalline, AlNiB-NCys were synthesized by rapid solidification method in an arc-melt furnace or in an induction furnace. The effect of changing the addition ratio of boron on the crystallography, microstrural, crystal impurifications has been investigated for the Al3Ni20Bx ternary. The crystal structure of samples obtained using X-ray diffraction was examined. XRD analysis revealed that prepared samples have the polycrystalline nanometric face centered cubic structure. XRDLine profile analysis by Lorentzian and Gaussian distributions were used to study the microstructure and crystal imperfections of Al3Ni20Bx. Crystallite size and microstrain were estimated using Williamson-Hall plots for the major eight XRD peaks. The data obtained shows that when the metal content is increased, the lattice parameters and volume of unit cell are increased linearly with boron concentration increase. This behavior is believed to be associated with an increase in content B by up to 11% that is entered into the unit cell of the Al3Ni20Bx system.

Objective To evaluate mortality from sepsis and septic shock in Korea during the past 10 years, we conducted a systematic review and meta-analysis.Methods We searched six databases for studies on mortality from sepsis and septic shock in adult patients. Primary outcomes were 28- or 30-day mortality and in-hospital mortality from sepsis and septic shock. To assess the risk of bias, we used the Newcastle-Ottawa Scale and Risk of Bias 2 tools. The protocol is registered in PROSPERO (No. CRD42022365739).Results A total of 61 studies were included. The mortality rates from sepsis and septic shock at 28 or 30 days were 22.7% (95% confidence interval [CI], 20.0%–25.6%; I2=89%) and 27.6% (95% CI, 22.3%–33.5%; I2=98%), respectively, according to the Sepsis-3 criteria. Furthermore, in accordance with the Sepsis-3 criteria, the in-hospital mortality rates were 28.1% (95% CI, 25.2%–31.1%; I2=87%) and 34.3% (95% CI, 27.2%–42.2%; I2=97%), respectively.Conclusion The mortality rates from sepsis and septic shock in Korea are high. In the case of septic shock, the in-hospital mortality rate is approximately 30%.
