Apps in Clinical Practice: Usage Behaviour of Trauma Surgeons and Radiologists in Northern Germany

Introduction Apps, in general, are an integral part of our daily lives. To investigate the current usage behaviour of trauma surgeons and radiologists regarding medical apps in clinical practice and to find out if and how the current range of medical apps can be improved, we surveyed trauma surgeons and radiologists in northern Germany. Material and Methods. An online questionnaire was sent to 100 trauma surgeons and 100 radiologists in northern Germany. Participants were asked about the frequency of their use of medical apps in clinical practice, which apps were used most often, how useful participants thought apps were, and in which area they would like to see improvements. The most frequently mentioned apps were finally analyzed. Results The survey study showed that 87.4% of the trauma surgeons and 67.4% of the radiologists use medical apps on a regular basis at work. It also revealed that trauma surgeons used medical apps much more often than radiologists and that young doctors were more likely to rely on medical apps than chief physicians. 80.0% of the participants would pay at least 5 euros for a medical app. Trauma surgeons see the greatest need for support in their daily work from medical apps in the area of treatment, while radiologists seek more support in the area of classification. Conclusion The study underscored the broad acceptance of medical apps in everyday clinical practice. As the physicians are willing to spend money and stated a general interest and need for further developments, there is high potential for the future. This trial is registered with DRKS00026766.
Coincidence site lattices and coincidence site modules

A lattice in Euclidean d-space is called well-rounded if it contains d linearly independent vectors of minimal length. This class of lattices is important for various questions, including sphere packing or homology computations. The task of enumerating well-rounded sublattices of a given lattice is of interest already in dimension 2, and has recently been treated by several authors. In this paper, we analyse the question more closely in the spirit of earlier work on similar sublattices and coincidence site sublattices. Combining explicit geometric considerations with known techniques from the theory of Dirichlet series, we arrive, after a considerable amount of computation, at asymptotic results on the number of wellrounded sublattices up to a given index in any planar lattice. For the two most symmetric lattices, the square and the hexagonal lattice, we present detailed results. 7.
Metabolic Syndrome Rather Than Other Phenotypes in PCOS as a Predictive Indicator for Clinical Outcomes in IVF: Comprehensive Phenotypic Assessment across All PCOS Classifications

Polycystic ovary syndrome (PCOS) is a well-recognized, multi-system metabolic disorder affecting fertility. Although various classification methods have been proposed to assess the phenotypic heterogeneity of PCOS, there is currently no reliable phenotype for predicting clinical IVF outcomes. This retrospective study, as a comprehensive phenotypic assessment across all PCOS classifications, aimed to identify dependable phenotypes that can serve as predictors for IVF and pregnancy outcomes. The study included 1313 PCOS patients who received their initial IVF treatment between January 2019 and December 2021. The phenotypes reflect the diverse metabolic and hormonal characteristics in this study. Phenotype A, within the Rotterdam criteria classification, exhibited the highest anti-Müllerian hormone levels (AMH), while phenotype D displayed the lowest Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) values. Both the hyperandrogenism (HA) phenotype within HA-based classification and the overweight phenotype within the body-mass-index-based classification showed increased HOMA-IR and metabolic syndrome (MetS). The MetS phenotype had higher free androgen index and a lower AMH. Notably, the MetS-based classification system demonstrated an independent association of MetS with cumulative live birth, preterm birth, and gestational diabetes mellitus as a contributing risk factor for PCOS patients undergoing IVF (p < 0.05). These findings carry noteworthy implications for advancing clinical management strategies for PCOS.
Evaluation of a Webinar to Increase Health Professionals’ Knowledge about Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS)

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a severe chronic illness and patients with ME/CFS are often medically underserved in Germany and other countries. One contributing factor is health professionals’ lack of knowledge about epidemiology, diagnostic criteria, and treatment of ME/CFS. Opportunities are scarce for health professionals to receive continuing medical education on ME/CFS. The current research addressed this need for further education and investigated the gain of knowledge from a webinar for German-speaking health professionals. In two studies (total sample: N = 378), participants in the intervention condition completed a knowledge test twice (before and after webinar participation). Study 2 also included a waiting-list control condition with repeated response to the knowledge test without webinar participation between measurements. Results showed that at baseline, most participants had seen patients with ME/CFS, but confidence in diagnosing and treating ME/CFS was only moderate-to-low. In the intervention condition, but not in the control condition, knowledge about ME/CFS increased between the first and the second knowledge test. These results indicate that the webinar was successful in increasing health professionals’ knowledge about ME/CFS. We concluded that webinars can be a cost-efficient and effective tool in providing health professionals with large-scale continuing medical education about ME/CFS.
Cultural differences in the relations between expressive flexibility and life satisfaction over time

Background Expressive flexibility refers to the ability to assess situational demands and adjust one’s emotion expressions via enhancement or suppression. It has been associated with lower levels of depressive and anxiety symptoms and greater social acceptance. These relationships, however, have not yet been examined across cultures—where prior research has found cultural differences in norms on emotion displays and their associations with mental health. This study examined expressive flexibility across three cultural groups and their associations with life satisfaction and depressive symptoms over time. Methods 276 first-year college students (146 Asian American, 71 European Americans, and 62 Latinx Americans) completed two online surveys during the first (T1) and thirteenth week (T2) of the Fall 2020 academic semester. Results Results revealed no significant cultural group differences in the ability to enhance or suppress emotions. However, we found a significant ethnicity x enhancement ability interaction in predicting T2 life satisfaction, controlling for T1 life satisfaction, age, gender, and emotion regulation frequency. Specifically, greater ability to enhance one’s emotions was significantly associated with higher life satisfaction over time among Asian Americans, but not for European Americans and Latinx Americans. Discussion Our findings illustrate the importance of not looking just at cultural group differences in the levels of expressive flexibility, but also at the associations between expressive flexibility and mental health.
Connected (g, f)‐factors

In this paper we study connected (g, f)‐factors. We describe an algorithm to connect together an arbitrary spanning subgraph of a graph, without increasing the vertex degrees too much; if the algorithm fails we obtain information regarding the structure of the graph. As a consequence we give sufficient conditions for a graph to have a connected (g, f)‐factor, in terms of the number of components obtained when we delete a set of vertices. As corollaries we can derive results of Win [S. Win, Graphs Combin 5 ( 1989 ), 201–205], Xu et al. [B. Xu, Z. Liu, and T. Tokuda, Graphs Combin 14 ( 1998 ), 393–395] and Ellingham and Zha [M. N. Ellingham and Xiaoya Zha, J Graph Theory 33 ( 2000 ), 125–137]. We show that a graph has a connected [a, b]‐factor (b>a ≥ 2) if the graph is tough enough; when b ≥ a + 2, toughness at least $(a-1) + {a\over b-2}$ suffices. We also show that highly edge‐connected graphs have spanning trees of relatively low degree; in particular, an m‐edge‐connected graph G has a spanning tree T such that degT (υ) ≤ 2 + ⌈ degG(υ)/m⌉ for each vertex υ. © 2002 John Wiley & Sons, Inc.

Task-dependent signal variations in EEG error-related potentials for brain–computer interfaces

Objective. A major difficulty of brain–computer interface (BCI) technology is dealing with the noise of EEG and its signal variations. Previous works studied time-dependent non-stationarities for BCIs in which the user’s mental task was independent of the device operation (e.g., the mental task was motor imagery and the operational task was a speller). However, there are some BCIs, such as those based on error-related potentials, where the mental and operational tasks are dependent (e.g., the mental task is to assess the device action and the operational task is the device action itself). The dependence between the mental task and the device operation could introduce a new source of signal variations when the operational task changes, which has not been studied yet. The aim of this study is to analyse task-dependent signal variations and their effect on EEG error-related potentials.Approach. The work analyses the EEG variations on the three design steps of BCIs: an electrophysiology study to characterize the existence of these variations, a feature distribution analysis and a single-trial classification analysis to measure the impact on the final BCI performance.Results and significance. The results demonstrate that a change in the operational task produces variations in the potentials, even when EEG activity exclusively originated in brain areas related to error processing is considered. Consequently, the extracted features from the signals vary, and a classifier trained with one operational task presents a significant loss of performance for other tasks, requiring calibration or adaptation for each new task. In addition, a new calibration for each of the studied tasks rapidly outperforms adaptive techniques designed in the literature to mitigate the EEG time-dependent non-stationarities.
SELF EFFICACY , SELF ESTEEM , AND GENDER AS FACTORS PREDICTING HOMESICKNESS OF FRESHMEN

The transition from high school to college/university often involves separation from home as well as adapting to a new academic environment. For most new students, adjusting to an unfamiliar academic setting can induce homesickness. While most studies have investigated homesickness as a negative outcome of relocation, the present study extended the literature by examining the influence of self esteem, self efficacy, and gender on homesickness among freshmen in a public higher institution of learning in southwest Nigeria. The study was a cross-sectional ex post facto research, in which 306 respondents were selected using purposive sampling method. The sample comprised 193 females and 113 males, and their age ranged between 15 and 29 years with a mean of 20.13. The instrument for data collection was a well-designed self-report questionnaire that measured self efficacy, self esteem and homesickness. Three hypotheses generated from the literature reviewed were tested. Results indicated significant influence of both self efficacy {t (303) = 4.54, p <. 01}, and self esteem {t (303) = 5.50, p<. 01} on homesickness. However, gender had no significant influence on homesickness. The findings were discussed alongside implications and conclusions.
Dynamics and interpretation of some integrable systems via matrix orthogonal polynomials

ABSTRACT In this work we characterize a high-order Toda lattice in terms of a family of matrix polynomials orthogonal with respect to a complex matrix measure. In order to study the solution of this dynamical system, we give explicit expressions for the Weyl function, generalized Markov function, and we also obtain, under some conditions, a representation of the vector of linear functionals associated with this system. We show that the orthogonality is embedded in these structure and governs the high-order Toda lattice. We also present a Lax-type theorem for the point spectrum of the Jacobi operator associated with a Toda-type lattice.
Chasing the bird: 3D acoustic tracking of aerial flight displays with a minimal planar microphone array

ABSTRACT Tracking the flight patterns of birds and bats in three-dimensional space is central to key questions in evolutionary ecology but remains a difficult technical challenge. For example, complex aerial flight displays are common among birds breeding in open habitats, but information on flight performance is limited. Here, we demonstrate the feasibility of using a large ground-based 4-microphone planar array to track the aerial flight displays of the cryptic Jack Snipe Lymnocryptes minimus. The main element of male display flights resembles a galloping horse at a distance. Under conditions of sufficient signal-to-noise ratio and of vertical alignment with the microphone array, we successfully tracked male snipe in 3D space for up to 25 seconds with a total flight path of 280 m. The ’gallop’ phase of male snipe dropped from ca. 141 to 64 m above ground at an average velocity of 77 km/h and up to 92 km/h. Our project is one of the first applications of bioacoustics to measure 3D flight paths of birds under field conditions, and our results were consistent with our visual observations. Our microphone array and post-processing workflow provides a standardised protocol that could be used to collect comparative data on birds with complex aerial flight displays.
Community Needs Assessment as Basis for the Extension Program of Philippine College Foundation

Philippine College Foundation (PCF) has been working to enhance the quality of life of people in the community by delivering practical, relevant, and responsive extension programs. Community extension services facilitate collaborative effort and volunteerism between schools and their surrounding communities. This study examined the needs of the community in Barangay Bangcud, Malaybalay City, Bukidnon. Specifically, the survey aimed to ascertain the demographic profile of respondents and assess community needs. This study employed a descriptive mixed method that included a survey questionnaire and interviews with key informants. The study revealed that most of the respondents are between the ages of eighteen and twenty-four, have completed elementary school, and are employed as laborers. The majority of respondents have their own houses, but only a few have toilets. The community highly needs livelihood and financial literacy projects, organizational planning and management, and food safety and hygiene. Moreover, they have high necessity in terms of education, parenting, and awareness of human rights and violence. The study recommends that the institution and the Barangay Bangcud local government unit collaborate to provide projects that could meet the identified needs of the community. In addition, it is recommended that a strong linkage be established with the concerned agencies to ensure the success of the projects.
A Distinct Class of Slow ( (cid:2) 0.2–2 Hz) Intrinsically Bursting Layer 5 Pyramidal Neurons Determines UP/DOWN State Dynamics in the Neocortex

During sleep and anesthesia, neocortical neurons exhibit rhythmic UP/DOWN membrane potential states. Although UP states are maintained by synaptic activity, the mechanisms that underlie the initiation and robust rhythmicity of UP states are unknown. Using a physiologicallyvalidatedmodelofUP/DOWNstategenerationinmouseneocorticalsliceswherebythecholinergictonepresent invivo is reinstated, we show that the regular initiation of UP states is driven by an electrophysiologically distinct subset of morphologically identified layer 5 neurons, which exhibit intrinsic rhythmic low-frequency burst firing at (cid:2) 0.2–2 Hz. This low-frequency bursting is resistant to block of glutamatergic and GABAergic transmission but is absent when slices are maintained in a low Ca 2 (cid:3) medium (an alternative, widely used model of cortical UP/DOWN states), thus explaining the lack of rhythmic UP states and abnormally prolonged DOWN states in this condition. We also characterized the activity of various other pyramidal and nonpyramidal neurons during UP/ DOWNstatesandfoundthatanelectrophysiologicallydistinctsubsetoflayer5regularspikingpyramidalneuronsfiresearlierduringtheonsetofnetworkoscillationscomparedwithallothertypesofneuronsrecorded.Thisstudy,therefore,identifiesanimportantrolefor cell-type-specificneuronalactivityindrivingneocorticalUPstates.
Interplay of electronic, structural and magnetic properties as the driving feature of high-entropy CoCrFeNiPd alloys

The structural and magnetic properties of CoCrFeyNi and CoCrFeNi-Pdx alloys earlier investigated experimentally by x-ray and neutron diffraction techniques and magnetometry have been theoretically reproduced using two complementary approaches for electronic structure calculations, i.e. the Korringa–Kohn–Rostoker method with the coherent potential approximation (KKR-CPA) and implemented in the ab initio framework of density functional theory and the Vienna ab initio simulation package (VASP) for supercell models of high-entropy alloy (HEA) structures. The comparison between experimental results and calculations of the lattice constants by both calculation methods indicate that the structure of CoCrFeyNi is well described by ordered fcc configurations. The values of local magnetic moments on Fe, Co, Cr, and Ni atoms depend not only on the Pd concentration but on chemical disordering. In the case of the CoCrFeNi-Pdx alloys, the KKR-CPA and the VASP calculations of disordered configurations reproduce the experimental values at 5 K up to equimolar composition and at 300 K above. The experimental values above the equimolar composition at 5 K are not satisfactorily reproduced by any of the calculations. The divergence between the experimental and calculated values is related to the variation of the ferromagnetic to paramagnetic transition temperature as a function of palladium content and to the existence of several phases, FeCoCr-rich above room temperature and FeCrPd-rich below, observed by diffraction and detected by microscopy and atom probe investigations. VASP calculations of a FeCrPd-rich phase effectively reproduced both the lattice constant and magnetization of the alloy above equimolar composition. An important conclusion of this work is that the combined analysis of the electronic, structural, and magnetic properties plays an important role in understanding the complexity of magnetic HEAs.
Inspirational or Self-Deflating

This research examines the role of self-efficacy in women’s responses to elite leadership role models. Previous research on role models has been equivocal, demonstrating that the impact of social comparisons on the self is multifaceted. Using an experimental methodology, 102 female participants were presented with role models (elite, nonelite, control) before serving as the leader of an ostensible three-person group. Findings revealed that women with low, as opposed to high, levels of leadership self-efficacy were less inspired by the highly successful role models and showed deflating contrast effects as demonstrated in their diminished identification with leadership, leadership aspirations, and leadership performance. Moreover, the performance effects were mediated by participants’ identification with leadership. This research has identified an important self-regulatory variable that influences whether people engage in assimilative or contrastive processes when making strategic comparisons and it identifies the important role of self-perceptions in behavioral responses to role models.
On the cohomology of Rapoport-Zink spaces of Hodge type

We prove the conjecture of Harris on the cohomology of Rapoport-Zink spaces for unramified reductive groups, under the "Hodge-Newton decomposibility" assumption. Our proof is based upon Mantovan's previous result for EL/PEL cases, combined with the "EL realization" of our Rapoport-Zink spaces.
Influenza surveillance: determining the epidemic threshold for influenza by using the Moving Epidemic Method (MEM), Montenegro, 2010/11 to 2017/18 influenza seasons

Background: In 2009, an improved influenza surveillance system was implemented and weekly reporting to the World Health Organization on influenza-like illness (ILI) began. The goals of the surveillance system are to monitor and analyse the intensity of influenza activity, to provide timely information about circulating strains and to help in establishing preventive and control measures. In addition, the system is useful for comparative analysis of influenza data from Montenegro with other countries. Aim: We aimed to evaluate the performance and usefulness of the Moving Epidemic Method (MEM), for use in the influenza surveillance system in Montenegro. Methods: Historical ILI data from 2010/11 to 2017/18 influenza seasons were modelled with MEM. Epidemic threshold for Montenegro 2017/18 season was calculated using incidence rates from 2010/11–2016/17 influenza seasons. Results: Pre-epidemic ILI threshold per 100,000 population was 19.23, while the post-epidemic threshold was 17.55. Using MEM, we identified an epidemic of 10 weeks’ duration. The sensitivity of the MEM epidemic threshold in Montenegro was 89% and the warning signal specificity was 99%. Conclusions: Our study marks the first attempt to determine the pre/post-epidemic threshold values for the epidemic period in Montenegro. The findings will allow a more detailed examination of the influenza-related epidemiological situation, timely detection of epidemic and contribute to the development of more efficient measures for disease prevention and control aimed at reducing the influenza-associated morbidity and mortality.
