Monogenic Lupus Is a Construct: Insights into the Current Nomenclature and Classification
Authors: Akbar Lujayn , Al-Mayouf Sulaiman M.
Published: December 2022

Monogenic lupus is a rare inherited entity, which has been increasingly recognized over the past decade. Monogenic lupus demonstrates heterogeneity in etiopathogenesis, phenotypes, and outcome compared to sporadic systemic lupus erythematous (SLE). Its distinctive features include early-onset disease, atypical manifestations of underlying diseases such as immunodeficiency, immune dysregulation, and refractory disease course. The term “monogenic lupus” has been used internationally to collectively describe a group of patients presenting with SLE or SLE-like symptoms with a proven underlying pathogenic variant. It has been considered a form of SLE irrespective of the differences observed. To date, there is no standardized definition or criteria to identify monogenic lupus. Therefore, this review highlights the differences between monogenic lupus and sporadic SLE to discuss the challenges related to the current nomenclature and unmet needs in the diagnosis of monogenic lupus. A considerable number of underlying pathogenic variants have recently been uncovered, leading to various pathways’ involvement with significant overlap. This allows us to propose a new definition for monogenic lupus which can be considered as a construct rather than a disease or syndrome.

Published: December 2022

At present, the domestic demand for long-term care is growing rapidly. However, the replenishment of related services has been slow. This leads to an imbalance in the proportion of nursing staff. The result was a shortage of manpower and a hectic work schedule. If there is a system to assist caregivers in their daily work processes, the burden on caregivers reduces. The constructed system in this research has the functions of Bluetooth indoor positioning, abnormal state judgment, early warning with processing flow control, active reminder, and recording of nursing work. Indoor positioning is used to instantly locate the elderly, know their activity statuses, and determine whether the activity is abnormal. In the event of possible abnormal conditions, active and passive alerts are issued. Through the combination of software and hardware, the processing flow is controlled to achieve the optimal allocation of manpower. In addition, proactively reminding the attendant and recording the care items before carrying out the care needs are conducted to avoid omission or duplication of care items.

Published: December 2022

The prognostic assessment of an ICU patient involves assessing the severity of their condition, interventions, and length of ICU stay. Over the past 30 years, researchers have proposed numerous predictive models and severity assessment scales for ICU patients in specific regions, including APACHE II and SAPS II. However, most existing methods rely heavily on curve fitting which do not account for misclassifications caused by false negatives and positives. Specificity and sensitivity must be provided as an indicator of model performance. The primary aim in this study is to develop a machine-learning model to formulate a prognosis for MICU and SICU patients by using data from the MIMIC-IV for training. The predictive models developed in this study facilitate the prediction of mortality and other outcomes across various treatment regimens.

Review of Deep Learning Methods for Individual Treatment Effect Estimation with Automatic Hyperparameter Optimization
Authors: Sirazitdinov Andrei , Buchwald Marcus , Hesser Jürgen , Heuveline Vincent
Published: December 2022

Abstract—Estimation of individual treatment effect (ITE) for different types of treatment is a common challenge in therapy assessments, clinical trials and diagnosis. Deep learning methods, namely representation based, adversarial, and variational, have shown promising potential in ITE estimation. However, it was unclear whether the hyperparameters of the originally proposed methods were well optimized for different benchmark datasets. To solve these problems, we created a public code library containing representation-based, adversarial, and variational methods written in TensorFlow. In order to have a broader collection of ITE estimation methods, we have also included neural network based meta-learners. The code library is made accessible for reproducibility and facilitating future works in the field of causal inference. Our results demonstrate that performance of most methods can be improved using automatic hyperparameter optimization. Additionally, we review the methods and compare the performance of the optimized models from our library on publicly available datasets. The potential of hyperparameter optimization may encourage researchers to focus on this aspect when creating new methods for inferring individual treatment effect.
Signal Averaging in Wavelet Domain
Authors: Woldemariam Leah , Srivastava Madhur
Published: December 2022

We present a method to implement signal averaging using wavelet transforms. Signal averaging plays an essential role in reducing noise from physical experiments, but is currently performed outside wavelet transforms and removes the information of individual data points or experimental scans. We introduce the conditions that need to be satisfied to implement signal averaging using wavelet transforms, showing that only the Haar wavelet can be used to obtain signal-averaged information. Our method identifies the wavelet component that contains the signal-averaged value and develops a procedure to recover it. The method is tested on model data using varied amounts of Gaussian and Poisson noise at different data lengths as well as experimental data from the Electron Spin Resonance (ESR) spectroscopy. While the Haar wavelet is successful in obtaining the mean, other wavelets yield weighted averages. The incorporation of this method enables signal averaging and analysis to be carried out simultaneously in the wavelet domain, expanding the application of wavelet transforms and improving wavelet analysis. The code is available via GitHub and denoising.cornell.edu, as well as the corresponding author's group website (signalsciencelab.com).
Estimation of the effective irradiance and bifacial gain for PV arrays without the use of rear-side irradiance meters
Authors: Abe Caio Felippe , Dias João Batista , Notton Gilles , Faggianelli Ghjuvan Antone , Pigelet Guillaume , Ouvrard David
Published: December 2022

Bifacial photovoltaic modules are able to convert the solar radiation reaching their front and rear-sides, which means that more electricity can be produced using the same array area as monofacial modules with similar ratings. In some locations, the cost per power for such a technology has become cost-competitive with onventional monofacial modules. The so-called effective irradiance and the bifacial gain are useful metrics, respectively, to assess the solar resource and the performance of bifacial arrays. To calculate the effective irradiance, studies previously published employ rear-side irradiance measurements. In turn, to compute the bifacial gain, other works make use of monofacial modules with rating similar to those of the bifacial modules under analysis. In this paper, a straightforward method is presented, allowing the calculation of the effective irradiance without the requirement of measuring the rear-side irradiance; and to calculate the bifacial gain without the need of a monofacial module. The proposed method was experimentally tested using an outdoor platform with a dual-axis tracking system with bifacial modules. The international standard IEC-60891 was taken as a reference for monofacial power calculations, showing coherent results when compared to the calculated front-side bifacial module performance. The method should be useful for the quantification of the effective irradiance and the bifacial gain for PV installations which do not make use of extensive monitoring hardware.
On the Performance of LoRa-Enabled Backscatter Communication
Authors: Ali Abubakar Sani , Bariah Lina , muhaidat sami , Sofotasios Paschalis C. , Al-Qutayri Mahmoud
Published: December 2022

The wireless networks of the future are evolving to enable reliable communication for resource-constrained, miniaturized internet of things (IoT) devices, which will place stringent demands on future sixth-generation (6G) mobile networks. These demands include low cost, very low latency, improved spectrum, and power efficiency, higher reliability, and significantly improved data rates. Emphasizing that these devices have limited functionality and may be placed in inaccessible locations, replacing or recharging batteries can be a daunting task, so energy-efficient solutions should be developed to ensure uninterrupted, seamless wireless communication for the power-constrained IoT devices. In this paper, we consider the integration of long-range (LoRa) modulation into backscatter communications (BackCom), and we develop a mathematical framework in order to investigate the error rate performance of the considered system model. In particular, we derive novel exact and approximated closed-form expressions for the symbol error rate (SER), under the assumption of canceled radio-frequency (RF) interference. The obtained analytical results, corroborated by numerical results, confirm the advantages of integrating LoRa into BackCom system as a low-complex technique in order to extend the transmission distance in power-limited backscatter devices.

In 2008 schreef Tine Van Regenmortel ter gelegenheid van haar aanstelling als lector ‘Empowerment en maatschappelijk kwetsbare groepen’ bij de Fontys Hogeschool Sociale Studies in Eindhoven de publicatie Zwanger van empowerment. Een uitdagend kader voor sociale inclusie en moderne zorg. Dit empowermentkader werd warm ont- haald, niet alleen binnen de Hogeschool waar het als centraal concept wordt gesteld voor de gehele opleiding sociale studies, maar ook daarbuiten, zowel door profes- sionals, door (organisaties van) kwetsbare burgers, als bij het beleid. De opdracht en uitdaging liggen nu in het concretiseren en toepassen van het empowermentpa- radigma. Empowerment is een verbindend kader dat zich leent voor verschillende kwetsbare groepen, verschillende contexten, werkvelden en sectoren. Empowerment overstijgt als gelaagd concept het individuele niveau en vraagt ook om doorvertalingen op onder meer het groeps- en buurtniveau, het organisatieniveau, op diverse beleidsniveaus en op het niveau van de brede samenleving. Praktijkgericht onderzoek uitvoeren vanuit het empowermentkader heeft tevens haar implicaties.
