Breathomics of Respiratory Diseases
Authors: Aroutiounian Vladimir M. 
Published: August 2022

In humans, respiratory disorders are common. Today, rapid, risk-free, and potentially low-cost diagnostics of respiratory disorders detected in the patient's exhaled air are critical. Fractional exhaled nitric oxide (FENO), volatile organic molecules, carbon monoxide, hydrocarbons, and hydrogen peroxide are among the inhaled biomarkers mentioned. Breathomics from exhaled volatile organic compounds and oximeters are also shortly discussed. The use of WO3 in FENO monitors is discussed. They large-scale produced and widely used in medical centers and clinics for diagnostics of respiratory diseases. Promising semiconductor sensors are manufactured from SnO2, doped with Pd, Au, or Pt or multi walls carbon nanotubes, gold nanoparticle with single wall carbon nanotubes, quartz microbalance devices with porphyrin, ITO –Zno-Pt films, and surface acoustic wave devices with isobutylene. A combination of VOCs is considered as a “molecular fingerprint” of breath. The electronic nose on metal oxide detectors allows investigating lung cancer and tuberculous.

ℒasso ℳ𝒫𝒞‐Based ℒ1 Adaptive Control for Uncertain Euler–Lagrange Systems: Guaranteed Stability Robustness and Performance
Authors: Ahmadian Hossein , Ali Talebi Heidar , Sharifi Iman 
Published: February 2025

ABSTRACTThe challenge of assessing system states and considering the robot's physical limitations impedes the development of an adaptive controller for robotic systems. To solve this challenge, this study proposes an adaptive controller based on ℒasso () (for Euler–Lagrange systems) that combines the method by a Barrier Lyapunov Function() and an adaptive high‐gain observer (). In the face of uncertainty, time delay, and inaccessibility of system states, the presented approach establishes a mechanism to compromise between fast adaptation and robustness. The constrains the system's outputs and adjusts the observer gain to ensure the output estimation error stays within a predetermined range. Then, to increase the prediction accuracy, ℒasso () uses the estimated system parameter (obtained by ). To manage additive and parametric uncertainties, the proposed approach adds a robustness constraint to the optimization. Subsequently, the effectiveness of the proposed method is assessed using an uncertain six‐degrees‐of‐freedom (6‐𝒟𝒪ℱ) remotely operated underwater vehicle (ℛ𝒪𝒱), and the stability of the closed‐loop system under input delay is evaluated. The extensive numerical results demonstrate that the system with the proposed controller achieves superior performance compared to other adaptive controllers, particularly in terms of integral absolute tracking and estimation errors for this specific application. Furthermore, the results validate the proposed approach's ability to reject uncertainties and disturbances that fluctuate over time, and they exhibit a satisfactory tracking performance even in cases where the system dynamics are uncertain.

ABSTRACTIn the present article, a selective and efficient sensor based on organosilane functionalized graphene oxide nanocomposites has been synthesized for the fluorometric detection of tyrosine (Tyr). The 1,2,3‐triazole functionalized organosilane has been synthesized by a condensation reaction between 4‐(methylthio) aniline and alkylated benzaldehyde followed by azide‐alkyne cycloaddition reaction using Cu (I) catalyst. The synthesized organosilane has been fabricated on graphene oxide nanoparticles and the obtained graphene‐functionalized organosilane (GO‐Silane) was characterized by FTIR and XRD. The morphology of the nanocomposite film was analyzed using scanning electron microscopy. The photophysical properties of GO‐Silane were studied which established its selective sensor for tyrosine with the limit of detection values of 1.04 × 10−8 M with a response time of 8 s. The strong coordinated interactions of GO‐Silane for the Tyr have been confirmed from FTIR spectra of the GO‐Silane‐Tyr complex. The competitive amino acid interference assay successfully demonstrated the selectivity of the nanocomposite sensor.
The osteology, taxonomy, and phylogenetic placement of Seeleyosaurus guilelmiimperatoris (Plesiosauroidea, Microcleididae) from the Lower Jurassic Posidonia Shale of Germany

AbstractSeeleyosaurus guilelmiimperatoris is an early‐diverging plesiosauroid from the lower Toarcian (Lower Jurassic) of the Posidonienschiefer Formation (Posidonia Shale) of Holzmaden, southwestern Germany. It is known from almost complete skeletons of two osteologically mature individuals, the holotype and a referred specimen that was largely destroyed during World War II. Although well‐preserved and substantially complete, the anatomy of Seeleyosaurus and its taxonomic and phylogenetic significance remain insufficiently understood. Here, we provide a complete osteological description of the taxon. Seeleyosaurus guilelmiimperatoris can be diagnosed based on a unique combination of characters, including one autapomorphy: the tall and basally constricted neural spines of the posterior cervical, pectoral, and dorsal vertebrae which have a sinusoidal shape in lateral view. Our study supports the validity of the plesiosauroid taxon Plesiopterys wildi, which was considered a junior synonym of Seeleyosaurus in a previous joint assessment of the taxa. Our phylogenetic evaluation places S. guilelmiimperatoris among Microcleididae, in congruence with previous studies. However, in contrast to earlier phylogenetic reconstructions, our analyses, which take into account numerous changes to the character matrix, reconstruct S. guilelmiimperatoris as falling within the Microcleidus clade. While we admit that Seeleyosaurus might potentially be considered a species of Microcleidus, we refrain from promoting this nomenclatural change pending an osteological and taxonomic reassessment of Microcleidus spp. as well as other, potentially closely related forms, such as Lusonectes sauvagei.
Holographic Connection of f(G) Gravity Through Barrow and a Generalized Version of Holographic Dark Fluid
Authors: Chattopadhyay Surajit 
Published: February 2025

ABSTRACTIn the study presented in this work, we use the holographic principle taking into account the Barrow entropy rather than the conventional Bekenstein–Hawking one to develop a holographic model for dark energy in the gravity. The former results from the attempt to include quantum gravitational effects into the cosmological framework and, in accordance with the gravity–thermodynamic conjecture, into black hole physics. To investigate the cosmological implications of our model for modified gravity, we discuss the cosmic implementation of the most generalized type of holographic dark energy, called Nojiri‐Odintsov holographic dark energy (NO‐HDE), and a particular example of it, called Barrow holographic dark energy. This is accomplished by adding to the model a well‐known power law form of the scale factor and the Holographic dark energy. It is found that the reconstructed satisfies a necessary condition for a realistic modified gravity model. Additionally, the reconstruction models are examined in the four energy scenarios. Lastly, the relationship to observational boundaries is examined, and the reconstructed EoS parameter is verified to fall within the constraints determined in the literature by utilizing observational data sets from BAO, SNLS3, and .

ABSTRACTMume Fructus (MF), a representative substance in the field of medicine‐food homology, has been extensively utilized in clinical treatments and daily diets for its raw and processed forms. This study aimed to establish the spectrum‐effect relationship between ultra–high‐performance liquid chromatography coupled with quadrupole tandem time‐of‐flight mass spectrometry (UHPLC‐Q‐TOF‐MS/MS) fingerprints and anti‐inflammatory and antitussive activities of raw and processed MF extracts. In UHPLC‐Q‐TOF‐MS/MS fingerprints, a total of 21 common peaks were identified. Bioactivity assays demonstrated that the raw and processed MF extracts exhibited varying degrees of anti‐inflammatory and antitussive effects. Subsequently, the relevant pharmacologically active ingredients were screened by grey relation analysis and partial least squares regression. The results showed that nine components were associated with anti‐inflammatory effects, namely, citric acid, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, fumaric acid, gallic acid, neochlorogenic acid, chlorogenic acid, and ononin. Additionally, three components were linked to antitussive activity: amygdalin, syringic acid, and succinic acid, respectively. This work developed a model combining UHPLC‐Q‐TOF‐MS/MS fingerprints with anti‐inflammatory and antitussive activities to study the spectrum‐effect relationship of raw and processed MF extracts. The findings provide a reference for the discovery of bioactive components and contribute to the clinical rationalization of medications.

Published: February 2025

ABSTRACTLife insurance coverage is steadily declining with only about half of Americans currently holding any type of life insurance. This trend suggests that a growing number of households may have inadequate financial resources in the case of death of an income earner. This study describes the characteristics of households who are financially inadequately protected in the event of income earners' deaths and examines the role life insurance product type and financial knowledge for adequate financial resources. We use the 2022 Survey of Consumer Finances limited to households with at least one member who holds full‐time employment, and living with two or more household members (n = 1818). We use repeated‐imputation inference (RII) logistic regression analyses to examine households with adequate life insurance holdings, adequate net financial assets, and adequate net worth in the event of income earners' deaths. The data show that the majority of households in this sample have inadequate financial resources to compensate for the death of an income earner (56%) and that this group shows greater financial and health‐related vulnerability. Through regression analysis, we find that all three adequacy measures were associated with life insurance product type, whereas financial knowledge was only intermittently significant. This study informs efforts to provide effective life insurance information and education.

Published: February 2025

ABSTRACTDespite the increased emphasis on motivating employees to go beyond their professions and positively impact society, our understanding of the factors that drive these social impact behaviors is still limited. Thus, the objective of this study is to investigate how employee social impact behaviors (ESIB) in service organizations are promoted by socially responsible human resource management (SRHRM) practices. Grounded in self‐determination theory, the study explores whether SRHRM influences ESIB through the mediating role of work meaningfulness (WM) and examines how servant leadership (SL) strengthens this relationship. Data from 268 service sector employees in the United Arab Emirates (UAE) were gathered via a structured, cross‐sectional survey. The results support the moderated mediation model. It also demonstrates that SRHRM significantly boosts ESIB, with its effect being more pronounced under high SL behavior. This study provides essential insights into how SL amplifies the effects of SRHRM on ESIB and offers practical recommendations for organizations seeking to develop a socially responsible workforce. Furthermore, it emphasizes the necessity of aligning HRM practices with corporate social responsibility objectives to achieve wider organizational and societal outcomes.

AbstractWe retrospectively analyzed the clinical characteristics of three ARE cases with delayed‐onset seizures treated at Peking University First Hospital and Sanbo Brain Hospital from May 2021 to January 2023. We also reviewed previously reported atypical cases of Rasmussen's encephalitis (RE) in the literature, summarizing onset symptoms, seizure symptomatology, imaging findings, electroencephalogram (EEG) results, treatment course, and prognosis. The onset age of the three cases ranged from 1 year and 9 months to 7 years and 5 months. All three initially presented with limb motor disorders, which progressively worsened. Two cases developed focal seizures within 1 month of onset, whereas the third case had no seizures over 3 years. Brain MRIs revealed progressive unilateral hemispheric atrophy with multifocal abnormal signals, and PET‐CT showed decreased metabolism in the affected hemisphere. EEGs exhibited asymmetric background rhythms with slow waves in the affected hemisphere. In the two children with seizures, epileptiform discharges from the affected hemisphere were recorded, including one case of sustained partial epilepsy. One child was initially diagnosed with autoimmune encephalitis, whereas two were suspected of having RE at onset. The two children with seizures were treated with immunotherapy and various antiseizure medications. Both underwent hemispherectomy because neither seizures nor limb motor disorders were effectively controlled. Post‐surgery, neither experienced seizures during 2 years of follow‐up, and both showed cognitive and motor improvements. The child without seizures received intermittent steroids and immunoglobulin therapy over 3 years. During 18 months of follow‐up, the patient's motor function improved, and no seizures occurred. Seizures are common initial symptoms of RE. Such cases are often misdiagnosed or missed, leading to delays in optimal treatment. If symptoms are predominantly unilateral and EEG and imaging findings show laterality, the possibility of RE should be considered. Early diagnosis and treatment can reduce unnecessary investigations and improve prognosis.Plain Language SummaryRasmussen's encephalitis (RE) is a rare disease that typically begins with seizures and generally has a poor prognosis. However, over the past 20 years, there have been reports of RE cases where the initial symptoms are not seizures. Our center has diagnosed and treated three such cases in the past 5 years. We aim to provide an overview of these atypical RE patients, focusing on clinical features, electroencephalographic (EEG) findings, and imaging characteristics to inspire early detection and diagnosis of RE, thus improving treatment timing and outcomes for RE patients.
Research on the Applicability of Hybrid RANS/LES Models to Predict the Flow Behavior in Bulb Tubular Pump Under Rated and Stall Conditions

Published: February 2025

ABSTRACTThe investigation into the internal flow characteristics of the bulb tubular pump device has important practical significance for improving both optimal design and operation stability. This paper uses different RANS/LES turbulence models to conduct numerical simulation research on the bulb tubular pump model device, specifically focusing on the differences in internal flow characteristics under the small flow stall condition 0.5Qdes and the design condition 1.0Qdes. The macroscopic energy characteristics of different turbulence models are verified through experiment tests, revealing that the DDES turbulence model provides better predicted hydraulic performance under stall conditions. The numerical difference under low flow conditions is mainly due to the different degrees of turbulent flow field analysis, while the analysis degree of high‐efficiency flow rate conditions with uniform internal flow remains similar. The vortex identification method Omega is used to visualize the vortex structure characteristics of the time‐averaged flow field, uncovering large‐scale stall vortex structures under small flow conditions, with the blending RANS/LES turbulence model offering superior resolution of vortex structures. Furthermore, the paper deduces the calculation method of the RANS/LES turbulence model pulsation entropy production based on the SST turbulence model pulsation entropy production calculation formula. A comprehensive investigation of the local power loss characteristics of the main flow‐passing components—impeller, diffuser, and bulb—reveals that the blades and wall surfaces are the main contributors to increase in power losses. The comparison shows that the DDES turbulence model provides more accurate predictions of the hydraulic performance of stall conditions and visualizing flow field characteristics.
