Authors: Korte Riikka , Takala Timo 
Published: January 2024

AbstractThe John–Nirenberg spaces$$JN_p$$JNpare generalizations of the space of bounded mean oscillationBMOwith$$JN_\infty =BMO$$JN∞=BMO. Their vanishing subspaces$$VJN_p$$VJNpand$$CJN_p$$CJNpare defined in similar ways asVMOandCMO, which are subspaces ofBMO. As our main result, we prove that$$VJN_p$$VJNpand$$CJN_p$$CJNpcoincide by showing that certain Morrey type integrals of$$JN_p$$JNpfunctions tend to zero for small and large cubes. We also show that$$JN_{p,q}(\mathbb {R}^n) =L^p(\mathbb {R}^n) / \mathbb {R}$$JNp,q(Rn)=Lp(Rn)/R, if$$p = q$$p=q.
Assessment Criteria of Innovations Risks: Analysis of Research Results
Authors: Deptuła Anna M. 
Published: January 2024

Abstract
In the times marked by sustainable economic development, innovations form the basis for operations aimed at economic development. In order to secure their implementation and achieve the projected goals, an adequate risk assessment is necessary. The evaluation criteria utilized in practice include a wide range of analytical aspects, from legal regulations and requirements related to environmental impact assessment to technical and economic issues. The paper reports outcomes of research aimed at defining the priority criteria for assessing the risk of innovation and their updating in relation to the new conditions for the performance of enterprises related to, among others, with the COVID-19 pandemic. As a consequence of this, it will be possible to establish a new hierarchy of evaluation criteria that could significantly affect the decision-making processes regarding implementing or rejecting specific innovative projects. The paper presents the results of questionnaire responses that involved Polish innovators: experts, constructors/designers, entrepreneurs, and scientists. The study involved experts from various industries (among others: energy, production, and the food or wood industry).
A probabilistic approach for estimating spring discharge facing data scarcity
Authors: Mirabbasi Rasoul , Nazeri Tahroudi Mohammad , Sharifi Alireza , Torabi Haghighi Ali 
Published: January 2024

AbstractSince spring discharge, especially in arid and semiarid regions, varies considerably in different months of the year, a time series of spring discharge observations is needed to determine the firm yield of the spring and the amount of water allocated to different needs. Because most springs are in mountainous and inaccessible areas, long-term observational data are often unavailable. This study proposes a probabilistic method based on bivariate analysis to estimate the discharge of the Absefid spring in Iran. This method constructed the bivariate distribution of the outflows of Absefid (AS) and Gerdebisheh (GS) springs using Copula functions. For this purpose, the fit of 11 different univariate distributions to the discharge data of each spring was tested. The results revealed that the GEV and log-normal distributions best fit the discharge data of GS and AS springs, respectively. In addition, among eight different copula functions, the Joe copula function was selected to construct the bivariate distribution of the discharge data of AS and GS springs. With the help of the created bivariate distribution and assuming a certain probability level, it is possible to estimate the discharge of Absefid spring based on the discharge of Gerdebisheh spring in a particular month. The estimated values of the discharge of the Absefid spring in the period from March 1993 to August 2022 show that with a probability of 90%, the lowest discharge of this spring is 600 L per second and occurred in June 2001. Therefore, to allocate the water from this spring for drinking purposes, this discharge value can be considered as the firm yield of this source. However, the amount of allocated water from this source should be determined by considering the ecological needs of the river downstream of this spring.
Superior UVC light-mediated catalytic activity of a novel NiFe2O4@ TiO2 magnetic nanocomposite synthesized with green route using Pulicaria Gnaphalodes plant extract for enhanced photocatalytic degradation of an antibiotic in water solution
Authors: Derakhshani Elham , Naghizadeh Ali , Mortazavi-Derazkola Sobhan 
Published: January 2024

AbstractIn this study, the NiFe2O4@TiO2 magnetic nanocomposite was synthesized by the green synthesis method, which is an efficient and economical method. Pulicaria Gnaphalodes plant extract was used for nanocomposite synthesis because this method is suitable for the biosynthesis of nanocomposites on a large scale, and the nanocomposite produced by plants is more stable. The efficiency of the synthesized nanocomposite was investigated for the photocatalytic degradation of Penicillin G (PNG) under UVC light irradiation in aqueous solutions. The structural characteristics of this nanocomposite were determined by field emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, vibrating sample magnetometer, and dynamic light scattering. The effect of different parameters including pH, nanocomposite dose, penicillin G concentration and time were studied to reach optimum conditions. About 71% of PNG in optimal conditions (pH = 9, nanocomposite dose = 0.6 g/L, and penicillin G concentration = 10 mg/L) was decomposed. Generally, the NiFe2O4@TiO2 nanocomposite can be used as an efficient catalyst for the degradation of PNG in aqueous solutions.
Quantitative reasoning as a lens to examine changes in modelling competencies of secondary preservice teachers
Authors: Nguyen An Thi Tan , Tran Dung 
Published: January 2024

Abstract
This study draws on quantitative reasoning research to explain how secondary mathematics preservice teachers’ (PSTs) modelling competencies changed as they participated in a teacher education programme that integrated modelling experience. Adopting a mixed methods approach, we documented 110 PSTs’ competencies in Vietnam using an adapted Modelling Competencies Questionnaire. The results show that PSTs improved their real-world-problem-statement, formulating-a-model, solving-mathematics, and interpreting-outcomes competencies. Showing their formulating-a-model and interpreting-outcomes competencies, PSTs enhanced their quantitative reasoning by properly interpreting the quantities and their relationships using different representations. In addition, the analysis showed a statistically significant correlation between PSTs’ modelling competencies and quantitative reasoning. Suggestions for programme design to enhance modelling competencies are included.
The Shape of Relations to Come: Multidimensional Analyses of Complex Human Behavior
Authors: Mason Lee , Andrews Alonzo , Otero Maria , James-Kelly Kimberly 
Published: January 2024

Abstract
Science, understood to be the behavior of scientists, falls within the purview of behavior analysis. All scientists use scientific instruments to study a natural phenomenon, and for the behavior analyst, perhaps no tool is more important than the graph used to show changes in level, trend, and variability, and upon which behavior analysts make data-based decisions. Modern behaviorism as we know it dates back to the development of the cumulative recorder first developed in the 1930s. Though revolutionary to the science of behavior, two-dimensional graphs may be limited in application for analyzing complex human behavior. In the current article, we conceptualize verbal behavior as a multidimensional field of environmental relations, and introduce the use of multi-axial radar charts for its visual and quantitative analysis. From there, we survey the use of radar charts toward advancing a behavior-analytic understanding of human language and cognition. We demonstrate the use of radar charts for calculating simple shape descriptors as a quantitative measure of dynamic interactants, and show how they can be used to measure change over time.

Published: January 2024

AbstractEmergency Medical Services (EMS) are crucial in delivering timely and effective medical care to patients in need. However, the complex and dynamic nature of operations poses challenges for decision-making processes at strategic, tactical, and operational levels. This paper proposes an action-driven strategy for EMS management, employing a multi-objective optimizer and a simulator to evaluate potential outcomes of decisions. The approach combines historical data with dynamic simulations and multi-objective optimization techniques to inform decision-makers and improve the overall performance of the system. The research focuses on the Friuli Venezia Giulia region in north-eastern Italy. The region encompasses various landscapes and demographic situations that challenge fairness and equity in service access. Similar challenges are faced in other regions with comparable characteristics. The Decision Support System developed in this work accurately models the real-world system and provides valuable feedback and suggestions to EMS professionals, enabling them to make informed decisions and enhance the efficiency and fairness of the system.
Stability of Hydroelastic Waves in Deep Water
Authors: Blyth M. G. , Părău E. I. , Wang Z. 
Published: January 2024

AbstractTwo-dimensional periodic travelling hydroelastic waves on water of infinite depth are investigated. A bifurcation branch is tracked that delineates a family of such solutions connecting small amplitude periodic waves to the large amplitude static state for which the wave is at rest and there is no fluid motion. The stability of these periodic waves is then examined using a surface-variable formulation in which a linearised eigenproblem is stated on the basis of Floquet theory and solved numerically. The eigenspectrum is discussed encompassing both superharmonic and subharmonic perturbations. In the former case, the onset of instability via a Tanaka-type collision of eigenvalues at zero is identified. The structure of the eigenvalue spectrum is elucidated as the travelling-wave branch is followed revealing a highly intricate structure.

AbstractEmpirical studies on yoga have shown that regular practice can have a beneficial effect on risk factors of cardiovascular diseases; also, it can decrease body weight, body fat and increase muscle mass. Positive effects on balance and flexibility were also reported. This study evaluated the impact of a 3-month complex yoga-based program, including physical exercises, education, and social support, with a quasi-randomized design in a middle-aged community sample. The intervention group consisted of 46 participants while the passive control group was 29 participants. The intervention group showed a significant increase in core muscle strength and hamstring flexibility and a decrease in body fat. No significant changes were found concerning risk factors of cardiovascular diseases, body weight, muscle mass, balancing ability, and dietary habits. A 3-month yoga intervention cannot substantially impact the cardiovascular system and body weight control in middle-aged adults.

Authors: Mojas Egoitz , Angulo Garazi , Coca Aitor , Castañeda-Babarro Arkaitz , Cacicedo Jon 
Published: January 2024

Abstract

Purpose
The aim of this review was to collect data on physical exercise programs in patients with HNC and to analyze the compliance with the Frecuency, Intensity, Time and Type (FITT) and progressive overload principles.

Methods
The search strategy identified 1318 articles through February 2022. After deduplication, title and abstract review, and full-text review, 15 studies met all the inclusion criteria. The inclusion criteria were randomized controlled trials (RCTs) with interventions involving at least 10 patients, and the intervention protocol included, at least, programmed strength exercise.

Results
Physical exercise programs were performed only during and after treatment, with durations varying from 6 to 12 weeks. Only 5 studies (33.3%) detailed all the characteristics concerning FITT and progressive overload principles. In addition, 10 trials measured the changes in body composition and physical function. In contrast, 6 studies included nutritional recommendations or follow-up.

Conclusion
It has been proven that physical exercise programs may help people with head and neck cancer improve their body composition, strength, and quality of life. To examine the dose/response effects of physical activity more precisely, further information regarding FITT principles and the progression of the load undertaken in the treatments is required. Finally, it is necessary to investigate the optimal time to start a physical exercise program and its impact on survival.
STM studies for surface-mounted molecular rotors: a mini review
Authors: Yang Tianyi , Zhang Ruiqin 
Published: January 2024

AbstractA molecular rotor is a molecule/molecular system that performs rotary motions under an external stimulus. Molecular rotors are promising for applications in medicine, optical usage, information science, etc. A molecular rotor is also a crucial component in constructing more sophisticated functional molecular machines. Anchoring molecular rotors on surfaces is regarded as a feasible way of building functional molecular rotor systems. Scanning tunneling microscope (STM) is a powerful tool for studying surface dynamics in real space on atomic precision. It provides an ideal platform for both qualitatively and quantitively investigating single and self-assembled molecular rotors mounted on surfaces. Herein, we review a series of studies utilizing STM to unveil the methodologies that are increasingly used in the area of surface-mounted molecule rotors. A combined usage of these methodologies is more and more necessary for researchers to advance the molecular rotor study in future.
Sample preparation conditions for the real-time measurement of W/O emulsions by resonance-enhanced multiphoton ionization time-of-flight mass spectrometry
Authors: Minami Minori , Nakata Shion , Uchimura Tomohiro 
Published: January 2024

AbstractAnalysis of an emulsion in its original dispersed condition is quite important for quality assessment and quality control. In the present study, the practical experimental conditions of the real-time measurement of a water-in-oil (W/O) emulsion were examined via resonance-enhanced multiphoton ionization time-of-flight mass spectrometry (REMPI-TOFMS). A W/O emulsion was prepared using cyclohexane as the oil phase with toluene as an analyte species. A time profile of the peak area for toluene was constructed based on the mass spectra. Normally, the negative spikes of a base signal are detected in a time profile when analyte molecules are dispersed in an oil phase. In this case, however, the positive spikes were unexpectedly detected rather than the negative ones. Though several factors could be relevant for the occurrence of the positive spikes, these spikes could have been suppressed by the addition of a small amount of n-alkane when the oil phase was prepared in the present study. The practical experimental conditions for the analysis of a W/O emulsion in real-time revealed that this method would be applicable to the analysis of an oil-in-water-in-oil (O/W/O) emulsion where the outer phase is also an oil phase.

Impact of the PCMH model on post-stroke healthcare utilization
Authors: Chen Ko-Shin , Wu Meng , Efferen Linda S. 
Published: January 2024

AbstractThe patient-centered medical home (PCMH) model has aimed to enhance chronic care in a primary care setting where providers are expected to provide timely post-discharge follow-up and decrease potentially preventable hospital readmissions through coordinated disease management. The study examined PCMH and other (risk) factors associated with 30-day unplanned readmission as well as 7- and 28-day follow-up visit with primary care providers (PCPs). We identified 8424 New York State Medicaid patients having initial stroke discharges during 2016–2018 from the Medicaid claims database and Statewide Planning and Research Cooperative System. A patient was in the PCMH group if the attributed provider had a valid National Committee for Quality Assurance PCMH recognition upon patient’s discharge. Cox regression and competing risk analyses were used to estimate the hazard ratios of readmissions and follow-up visits between PCMH and non-PCMH groups. The PCMH group had slightly but not statistically significant lower all-cause and recurrent stroke unplanned readmission rates. While the general follow-up rates between the two groups are similar, the PCMH group had significantly higher rates of stroke-specific 7-day (HR = 1.27, P < 0.01) and 28-day follow-up visits (HR = 1.22, P < 0.01). PCPs play an essential role in post stroke care. Our findings show a significantly higher rate of stroke-specific follow-up visits and a trend towards lower readmissions among patients in the PCMH group. The intervals between stroke discharge and follow-up visit time in our study population were generally greater than the recommended timeframe. We recommend the PCMH care model to improve patients’ primary care follow-up and prevent potential readmissions.
Sexuell übertragbare Infektionen bei Frauen in der hausärztlichen Praxis – eine qualitative Interviewstudie mit Hausärzt:innen in Berlin
Authors: Meurer Pauline , Heintze Christoph , Schuster Angela 
Published: January 2024

Zusammenfassung
Hintergrund
Sexuell übertragbare Infektionen (STI) sind in bis zu 90 % asymptomatisch, werden bei Frauen später erkannt und können zu schweren Komplikationen führen. Im deutschen Gesundheitssystem gibt es für Beratungsanlässe zu sexueller Gesundheit keine klar zuständigen Ansprechpartner:innen. So werden Patient:innen auch an Hausärzt:innen (HÄ) verwiesen, die sich bei diesem Thema jedoch häufig unsicher fühlen.

Ziel der Arbeit
In diesem Artikel werden konkrete hausärztliche Herangehensweisen in der STI-Versorgung bei Frauen beschrieben und diskutiert.

Methoden
Die Daten wurden mit teilstandardisierten Leitfadeninterviews mit Fallbeispielen zwischen Oktober 2020 und September 2021 erhoben und mit qualitativer Inhaltsanalyse ausgewertet. Auf Grundlage eines theoretischen Sampling-Ansatzes wurden 13 HÄ ohne infektiologischen Schwerpunkt und 6 HÄ in infektiologischen Schwerpunktpraxen (HÄiS) eingeschlossen.

Ergebnisse
Hausärzt:innen beschreiben, die Versorgung von Ratsuchenden finde eher in der Gynäkologie statt. Die Sexualanamnese würde selten erhoben und der Fokus liege eher bei Diagnostik und Behandlung von Harnwegsinfekten. Einzelne HÄ bieten dagegen Urin-PCR-Tests oder vaginale Selbstabstriche und Therapie für alle STI außer HIV an. Bestehende Abrechnungsmöglichkeiten und Angebote des Gesundheitsamts werden selten genutzt, asymptomatische Patient:innen müssen die Kosten für STI-Tests häufig selbst übernehmen.

Diskussion
Obwohl sich viele Patient:innen eine hausärztliche STI-Versorgung wünschen, wird dies in Deutschland derzeit unzureichend abgedeckt. Sexualanamnese und diagnostische Möglichkeiten sollten zukünftig in der Aus- und Fortbildung von HÄ eine größere Rolle spielen. Eine Screeningstrategie, klare Zuständigkeiten und Überweisungspfade könnten Patient:innen und HÄ deutlich entlasten.
Efficacy of noncarbapenem therapy for the treatment of ceftriaxone-resistant Enterobacterales outside the urinary tract
Authors: Rausch Ethan P. , Alby Kevin , Wilson William 
Published: January 2024

Abstract

Objective:
To determine the safety of noncarbapenem versus carbapenem antibiotics for treatment of adults with documented infection caused by ceftriaxone-resistant infections outside the urinary tract.

Design:
Retrospective cohort of adult patients with a documented infection caused by an extended-spectrum β-lactamase (ESBL)–producing organism isolated between January 2018 and October 2021.

Setting:
An academic tertiary-care center.

Patients:
Adult patients with a documented infection caused by an ESBL-producing organism outside the urinary tract.

Methods:
The primary outcome was a composite of treatment failure defined as 30-day mortality, 30-day readmission, microbiological recurrence, and/or clinical worsening requiring antibiotic change. Secondary outcomes included differentiation of primary composite components and postantibiotic Clostridioides difficile infection (CDI).

Results:
This study included 130 patients. The primary source of infections were bloodstream (67.7%) and caused by Escherichia coli (81.5%). Overall, 101 patients received carbapenem therapy and 29 received noncarbapenem therapy (NCT). NCT was comprised of mainly fluoroquinolones (18 of 29) followed by cefepime (7 of 29). Patients receiving NCT had shorter hospital stays (median, 7 days vs 9 days) and were more often discharged on antibiotics (79.3% vs 50.5%). We did not detect a significant difference in the primary composite outcome of treatment failure for carbapenem (23.8%) versus noncarbapenem treatment (24.2%; P = .967). Secondary outcomes included a numerically higher 30-day mortality rate in the noncarbapenem group compared to the carbapenem group: 4 (13.8%) of 29 versus 4 (3.9%) of 101. We did not detect a difference in rates of CDI.

Conclusion:
Noncarbapenem therapy may play a role for certain patients with infections caused by ESBL-producing organisms.
