Perfednilm: a practical personalized federated learning-based non-intrusive load monitoring
Authors: Pan Zibin , Wang Haosheng , Li Chi , Wang Haijin , Zhao Junhua 
Published: April 2024

AbstractNon-Intrusive Load Monitoring (NILM) is a valuable technique for breaking down overall power consumption into the energy usage of individual appliances. Understanding power usage patterns through NILM plays an important role in reducing energy costs and achieving carbon reduction goals. However, privacy concerns often deter consumers from sharing their electricity consumption data. To address these privacy concerns, Federated Learning (FL) has been introduced in NILM, which enables the training of NILM models while keeping power consumers’ data locally. However, FL’s reliance on a single global model leads to poor performance on clients with unique power consumption patterns. In response to this challenge, we present a Personalized Federated Learning NILM algorithm (PerFedNILM), a practical personalized FL approach for NILM. PerFedNILM limits the local update bias across clients and trains personalized models for individual clients to improve load-monitoring performance. In addition, it mitigates the negative impact of client dropout, which is a common issue in practice. Our experiments on using real-world energy data demonstrate that PerFedNILM outperforms previous FL-based NILM methods, especially in client dropout scenarios.

A digital twin (DT) of an open-plan common space is created, serving the purpose of remote room occupancy monitoring and automatic detection of energy consumption. A virtual reality (VR) model is developed and integrated to temperature, humidity and imaging sensors. For maintaining privacy, images are processed in local computers to measure occupancy levels and live video feed were never transmitted. The same set of imaging sensors were also used in a bespoke computer vision module for energy consumption estimation. The human avatars were mapped with high correlation (R$$^{2}$$

Published: April 2024

AbstractTriethylene glycol (TEG) removes equilibrium water from natural gas but may spill during equipment maintenance and other poor safety practices. Studies on the toxicity of rich TEG in aquatic habitats are scarce. In this study, the toxicity of rich TEG on freshwater juvenile African catfish (Clarias gariepinus) test organism was conducted. The experimental design for the toxicity tests was 3 × 5 × 6 factor in a randomized complete block design, with six levels of treatment, observed at five intervals and in three replicates. The acute toxicity was carried out by exposing them to various lethal concentrations of the Rich TEG in solution. Physicochemical parameters, including temperature, dissolved oxygen, pH, conductivity, and total dissolved solids, were measured and recorded for five test concentrations of 25.92, 12.96, 6.48, 3.24, 1.62, and 0.0 ml/l (control). The concentration responses for the fish mortality at 24, 48, 72, and 96 h were also derived. No mortality was observed between Rich TEG concentrations of 0 ml/l to 25.92 ml/l after 72 h of exposure. However, some mortality was observed between 1.62 ml/l to 25.92 ml/l after 96 h of exposure. The highest concentration of 25.92 ml/l recorded a higher mortality of 6.0 ± 0.4, which is an average of 60%, while the lowest mortality was recorded in the control (0 ml/l), at an average of 0% mortality rate. The results underscore the concentration-dependent effects of rich TEG on the test organism, highlighting the need for targeted attention to higher concentration levels.
Factors Contributing to Pharmacies With Good Disaster Preparedness and the Activities of Their Prefectural Pharmaceutical Association: Pharmacies’ resilience and associations
Authors: Ozeki Kayoko , Ojima Toshiyuki 
Published: April 2024

Abstract

Objective:
Pharmacies have a particularly important responsibility to supply medicine to disaster victims in order to save lives. This study investigated the characteristics of pharmacies that are well prepared for disasters as well as the efforts of the prefectural pharmaceutical association (PPA) to which the pharmacies belong.

Methods:
Questionnaires on matters related to disaster preparedness were mailed to 50 randomly selected pharmacies in each of Japan’s 47 prefectures as well as all 47 PPAs in Japan. Logistic regression analysis was performed to examine the association of pharmacy background and the activities of the PPA to which they belong with pharmacy disaster preparedness as well as the association with pharmacies’ awareness of disaster preparedness.

Results:
Pharmacies in prefectures that conducted disaster preparedness training at least three times a year were better prepared for disasters. In addition, pharmacies with high online utilization and high disaster-preparedness awareness were significantly more prepared for disasters.

Conclusions:
Pharmacies that can promptly provide medicine to disaster victims are considered to be well-prepared for disasters. The results suggest that pharmacy preparedness is also influenced by the disaster preparedness activities of their prefectures.
Immediate Adverse Reaction and SARS-CoV-2 Anti-Spike Receptor Binding Domain IgG of COVID-19 Vaccines Among Health Staffs
Authors: Rasheed Waleed S. , Sarkees Alaa Noori 
Published: April 2024

Abstract

Objective:
To contain the spread of coronavirus disease 2019 (COVID-19), several vaccines have been developed. This study is intended to elucidate the level of anti-severe acute respiratory syndrome coronavirus 2 immunoglobulin G (anti-SARS-CoV-2-IgG) antibodies for COVID-19 vaccines (Pfizer BioNTech [BNT162b2], Oxford/AstraZeneca [ChAdOx1], and Sinopharm [BBIBP-CorV]) among health staff from health facilities in Duhok province, and it explored the immediate adverse reactions of COVID-19 vaccines among participants.

Methods:
A longitudinal study was conducted from June 1, 2021, to June 30, 2022, and 300 participants were included through simple random sampling.

Results:
The immune response 1 mo after the second dose was significantly higher than the sustained immune after 5 and 9 mo as results revealed that, in 100% of study samples who had (ChAdOx1) vaccine, their antibody titers exceeded the positivity threshold of 1 AU/m, while 96% for (BNT162b2) and 90% for (BBIBP-CorV) for the first test after 1 mo from the second dose of the COVID-19 vaccine, and these rates were reduced to 94.6% for (ChAdOx1), 97.8% for (BNT162b2), and 81.9% for (BBIBP-CorV) at 5 mo after the second dose, while simultaneously the seropositivity rates were more reduced at 9 mo to 46.5% for (ChAdOx1), 67.5% for (BNT162b2), and 9.20% for (BBIBP-CorV). In terms of adverse reactionsss, fever was reported as the most prevalent after the first dose in 58% for ChAdOx1, 43% for BNT162b2, and 23% for BBIBP-CorV, followed by muscle pain, joint pain, and shoulder pain for both doses.

Conclusions:
The implications of the findings from this study are that higher and potentially longer antibody responses can be obtained if the BNT162b2 is given as compared with the other 2 vaccines. Moreover, the booster doses of the COVID-19 vaccine are highly recommended because more than 50% of the participants either have become anti-spike protein negative or have a deficient level of anti-spike protein against COVD-19 vaccines.
Regulatory Approaches Towards AI-Based Medical Device Cybersecurity: A Transatlantic Perspective
Authors: Biasin Elisabetta , Kamenjašević Erik 
Published: April 2024

AbstractCybersecurity of medical devices has become a concrete concern for regulators and policymakers in the European Union and United States. Following the COVID-19 pandemic, there has been an increase in cyber-attacks on critical healthcare infrastructures and their IT systems, which have suffered service disruptions and put patients’ health and safety at risk. The increase in cyberattacks on healthcare infrastructure, including medical devices, exacerbated by the growing digitalisation of healthcare services in the EU and the US, has led legislators and regulatory bodies to pay more attention to cybersecurity. Cybersecurity of AI-based medical devices requires the assessment of three areas subject to evolving regulatory approaches: medical devices, Artificial Intelligence (AI), and cybersecurity. Although they may appear distinguished in regulatory matters, the existence of AI-based medical devices and their possible cyber vulnerabilities makes clear that the three are intertwined and deserve closer attention from a regulatory point of view. Few scholars have devoted attention to AI and cybersecurity together. Even less, in our understanding, few comprehensive and EU/US comparative pieces of literature reflect on this specific issue. This paper aims to fill this gap and address the main implications of different regulatory approaches toward AI medical device cybersecurity in the EU and the US. The research stems from the assumption that regulation of medical devices in the EU has been historically inspired by regulatory trends in the US, although with the different cultural, societal, and legal traditions that made them adapt to the specificities of the territory. The paper observes that the US is a rule-based system reflecting a “command-and-control” approach, while the EU system is a principle-based one. While they share the main characteristic of being risk-regulation-based systems, their differences impact how AI-enhanced cybersecurity is regulated.
Similarities and differences between specification and non-uniform specification

Published: April 2024

AbstractPavlov [Adv. Math.295 (2016), 250–270; Nonlinearity32 (2019), 2441–2466] studied the measures of maximal entropy for dynamical systems with weak versions of specification property and found the existence of intrinsic ergodicity would be influenced by the assumptions of the gap functions. Inspired by these, in this article, we study the dynamical systems with non-uniform specification property. We give some basic properties these systems have and give an assumption for the gap functions to ensure the systems have the following five properties: CO-measures are dense in invariant measures; for every non-empty compact connected subset of invariant measures, its saturated set is dense in the total space; ergodic measures are residual in invariant measures; ergodic measures are connected; and entropy-dense. In addition, we will give examples to show the assumption is optimal.
Understanding the history of 1930s musical migrants to Britain through minimal computing-led digital humanities
Authors: Whitfield Sarah K. 
Published: April 2024

AbstractThis article explores how historical musicology can use computational methods within a minimal computing framework, recovering the performance histories of three migrant musicians, producing valuable new information about their careers. Líza Fuchsová, Maria Lidka, and Paul Hamburger all left Nazi-occupied Europe during the late 1930s and settled permanently in the UK. Fuchsová (1913-1977) was a Czech pianist who became an advocate for Czech musical culture as well as an important piano soloist; Hamburger (1920-2004) was an accompanist and teacher who left Vienna for London and became a senior figure in BBC radio and Guildhall professor; and Lidka (1914-2013) [Marianne Liedtke], was a violinist, orchestra leader and later Royal College of Music professor. Their careers have been underexplored, but machine-read digitised archives have opened new possibilities for finding and sorting what can seem like an overwhelming amount of performance data. This article uses a minimal computing led approach to demonstrate building a robust and accessible structure to interrogate performance data and establish performance histories. This article will demonstrate the value of this framework and will show how it can be applied to historical musicology work.
Unequal and Unsupportive: Exposure to Poor People Weakens Support for Redistribution among the Rich
Authors: Christensen Matias Engdal , Dinesen Peter Thisted , Sønderskov Kim Mannemar 
Published: April 2024

AbstractDo the rich become more or less supportive of redistribution when exposed to poor people in their local surroundings? Most existing observational studies find that exposure to poor individuals is positively associated with support for redistribution among the well-off, but one prominent field experiment found a negative link. We seek to resolve these divergent findings by employing a design closer to the studies that have found a positive link, but with more causal leverage than these; specifically, a three-wave panel survey linked with fine-grained registry data on local income composition in Denmark. In within-individual models, increased exposure to poor individuals is associated with lower support for redistribution among wealthy individuals. By contrast, between-individual models yield a positive relationship, thus indicating that self-selection based on stable individual characteristics likely explains the predominant finding in previous work.
A common multi-host parasite shows genetic structuring at the host species and population levels
Authors: Shaw Clara L. , Bilich Rebecca , Duffy Meghan A. 
Published: April 2024

AbstractAlthough individual parasite species commonly infect many populations across physical space as well as multiple host species, the extent to which parasites traverse physical and phylogenetic distances is unclear. Population genetic analyses of parasite populations can reveal how parasites move across space or between host species, including helping assess whether a parasite is more likely to infect a different host species in the same location or the same host species in a different location. Identifying these transmission barriers could be exploited for effective disease control. Here, we analysed population genetic structuring of the parasite Pasteuria ramosa in daphniid host species from different lakes. Outbreaks occurred most often in the common host species Daphnia dentifera and Daphnia retrocurva. The genetic distance between parasite samples tended to be smaller when samples were collected from the same lake, the same host species and closer in time. Within lakes, the parasite showed structure by host species and sampling date; within a host species, the parasite showed structure by lake and sampling date. However, despite this structuring, we found the same parasite genotype infecting closely related host species, and we sometimes found the same genotype in nearby lakes. Thus, P. ramosa experiences challenges infecting different host species and moving between populations, but doing so is possible. In addition, the structuring by sampling date indicates potential adaptation to or coevolution with host populations and supports prior findings that parasite population structure is dynamic during outbreaks.

A successful surgical management for a thrombosed giant left coronary aneurysm with right ventricular fistula in a young patient
Authors: Lu Yunyi , Wang Jing , Ma Liheng 
Published: April 2024

AbstractGiant coronary aneurysm with ventricular fistula is rare. Due to the limited data from randomised clinical trials, therapeutic strategies for coronary aneurysms predominantly rely on on case series and anecdotal evidences. Reporting cases that provide practical experience in managing these aneurysms is therefore crucial. In this article, we report a rare case of a successful surgical management for a thrombosed giant left coronary aneurysm with right ventricular fistula, which is larger than any previously reported cases.
Adaptive agents may be smarter than you think: unbiasedness in adaptive expectations
Authors: Palestrini A. , Gatti D. Delli , Gallegati M. , Greenwald B. 
Published: April 2024

Abstract
Experimental evidence shows that human subjects frequently rely on adaptive heuristics to form expectations but their forecasting performance in the lab is not as inadequate as assumed in macroeconomic theory. In this paper, we use an agent-based model (ABM) to show that the average forecasting error is indeed close to zero even in a complex environment if we assume that agents augment the canonical adaptive algorithm with a Belief Correction term which takes into account the previous trend of the variable of interest. We investigate the reasons for this result using a streamlined nonlinear macro-dynamic model that captures the essence of the ABM.
A combined EMDR/CBT-based approach for the successful management of cyclical vomiting syndrome: a case study
Authors: Ashcroft Kate 
Published: April 2024

Abstract
Cyclical vomiting syndrome (CVS) is an extremely debilitating condition that can have an adverse impact on physical health and can significantly disrupt social and occupational functioning. It is a poorly understood illness in terms of aetiology, and most research has focused on the pharmacological management of the condition. This article describes a case study of a combined cognitive behavioural therapy (CBT) and eye movement desensitisation and reprocessing (EMDR)-based intervention with an adult with past trauma who had a 20-year history of CVS accompanied by high cannabis use. Therapy led to improvements in physical health and social functioning, reduced use of cannabis, and a significant reduction in the frequency and severity of vomiting episodes and associated hospital admission. Implications for future research and management of the illness are discussed.

Key learning aims

(1)
To understand how the presence of co-morbid untreated trauma in individuals with CVS may result in unhelpful coping strategies that can worsen the course of the illness.

(2)
To explore how the addition of psychological therapy to routine care of gastrointestinal disorders such as CVS can improve treatment outcome.

(3)
To consider how offering an individualised and flexible approach to appointments may benefit individuals who find it more difficult to engage in psychological therapy.
Evolution Modeling and Protection Scheme for Tidal Flats Under Natural Change and Human Pressure, Central Jiangsu Coast
Authors: Zhu Shibing , Gao Shu , Li Mingliang , Wang Ya Ping 
Published: April 2024

AbstractAmidst escalating global changes and heightened human activities, tidal flats worldwide are facing a transition from accretion to erosion. In order to quantify the growth pattern of tidal flats and its response to changes in multiple external driving factors, here we established a geometric model, in combination with field surveys, to study the historical behavior (1127–1990) and future trends (2100) of a typical tidal flat system on the Jiangsu coast, China. The results indicate that sediment supply and relative sea level change determine the accretion‐erosion status and the eventual morphological pattern of the tidal flat. If these two factors remain stable and sediment supply can compensate for the increase in sediment accommodation space caused by sea level change, the tidal flat will continue to accrete until its growth limit is reached. Otherwise, tidal flats will face erosion risk, which can be further enhanced by localized land subsidence. Furthermore, changes in the coastal profile show a trend of progressive retreating, with the lower part of intertidal zone being eroded more rapidly than its upper part. This demonstrates that the sediment supply has been reduced to such a level that the present “in‐transition” evolution pattern of central Jiangsu coast will soon be replaced by severe inundation and erosion. Hence, we advocate for a comprehensive, multi‐tiered coastal protection strategy focusing on wave suppression, enhancement of sediment retention, and increased storm resistance. This strategy underscores fundamental underlying mechanisms of the accretion‐erosion transition, which is crucial for the future safeguarding of coastal wetlands globally.
Disagreements in Geodetically Inferred Strain Rates in the Western US With Stress Orientations and Geologic Moment Rates
Authors: Johnson Kaj M. 
Published: April 2024

AbstractI employ an elasticity‐based method to invert a geodetically derived surface velocity field in the western US using for present‐day surface strain rate fields with uncertainties. The method uses distributed body forces in a thin elastic sheet and allows for discontinuities in velocity across creeping faults using the solution for dislocations in a thin elastic plate. I compare the strain rate fields with previously published stress orientations and moment rates from geological slip rate data and previous geodetic studies. Geologic and geodetic moment rates are calculated using slip rate and off‐fault strain rates from the 2023 US National Seismic Hazard Model (NSHM) deformation models. I find that computed total geodetic moment rates are higher than NSHM summed moment rates on faults for all regions of the western US except the highest deforming rate regions including the Western Transverse Ranges and the northern and southern San Andreas Fault (SAF) system in California. Computed geodetic moment rates are comparable to the moment rates derived from the geodetically based NSHM deformation models in all regions. I find systematic differences in orientations of maximum horizontal shortening rate and maximum horizontal compressive stress in the Pacific Northwest region and along much of the SAF system. In the Pacific Northwest, the maximum horizontal stress orientations are rotated counterclockwise 40–90° relative to the maximum horizontal strain rate directions. Along the SAF system, the maximum horizontal stresses are rotated systematically 25–40° clockwise (closer to fault normal) relative to the strain rates.
