description: In this paper we undertake a study of the 21 square degree SMOG field, a Spitzer cryogenic mission Legacy program to map a region of the outer Milky Way towards the Perseus and Outer spiral arms with the IRAC and MIPS instruments. We identify 4648 YSOs across the field. Using the DBSCAN method we identify 68 clusters or aggregations of YSOs in the region, having 8 or more members. We identify 1197 class Is, 2632 class IIs, 819 class IIIs, of which 45 are candidate transition disk objects, utilizing the MIPS 24 photometry. The ratio of YSOs identified as members of clusters was 2872/4648, or 62%. The ratios of class I to class II YSOs in the clusters are broadly consistent with those found in the inner galactic and nearby Gould's Belt young star formation regions. The clustering properties indicate that the protostars may be more tightly bound to their natal sites than the class IIs, and the class IIIs are generally widely distributed. We further perform an analysis of the WISE data of the SMOG field to determine how the lower resolution and sensitivity of WISE affects the identification of YSOs as compared to Spitzer: we identify 931 YSOs using combined WISE and 2MASS photometry, 931/4648 or 20% of the total number identified with Spitzer. Performing the same clustering analysis finds 31 clusters which reliably trace the larger associations identified with the Spitzer data. Twelve of the clusters identified have previously measured distances from the WISE HII survey. SEDFitter modeling of these YSOs is reported, leading to an estimation of the IMF in the aggregate of these clusters which approximates that found in the inner galaxy, implying that the processes behind stellar mass distribution during star formation are not widely affected by the lower density and metallicity of the outer galaxy.

description: We prove general kernel theorems for operators acting between coorbit spaces. These are Banach spaces associated to an integrable representation of a locally compact group and contain most of the usual function spaces (Besov spaces, modulation spaces, etc.). A kernel theorem describes the form of every bounded operator between a coorbit space of test functions and distributions by means of a kernel in a coorbit space associated to the tensor product representation. As special cases we recover Feichtinger's kernel theorem for modulation spaces and the recent generalizations by Cordero and Nicola. We also obtain a kernel theorem for operators between the Besov spaces $\dot{B}^0_{1,1}$ and $\dot{B}^{0}_{\infty, \infty }$.

 Remarks. P. thaumasia has a strong tribladed apical horn, which differentiates it from P. kozoi (Pl. 39, Figs. 1–6) and P. stigi (Pl. 39, Figs. 7–9). It has randomly arranged pores on the thorax, which do not align along ribs, as in P. morawanensis (Pl. 40, Figs. 4A – 6, 9, 11–12) and P. cantharoides (Pl. 40, Figs. 1–3, 7–8, 10, 14). This species lacks strong ribs and prominent teeth at the base of the thorax. The specimens observed in the EEP appear to have a slightly more narrow thorax than those observed by Renaudie in the Southern Ocean, and those figured by Caulet (1991).
 Range. Middle Miocene—Pleistocene in the EEP (Table 1).

description: Nach der „republic of letters, einer Phase des intensiven Austauschs zwischen Forschern und Gelehrten im 17. und 18. Jahrhundert per Brief“ (Taubert 2017, S. 127), regulierte die meist an Verlage gebundene Verfügung über Druckerpressen jahrhundertelang das Format und die Verbreitung wissenschaftlicher Publikationen. Mit dem Internet sind nun Optionen entstanden, die erlauben, dass Wissenschaftlerinnen und Wissenschaftler die Kontrolle über ihr eigenes Publikationswesen zurückgewinnen, indem sie nicht nur als Autorinnen und Autoren oder Gutachtende tätig sind, sondern selbst Journals betreiben oder Buchreihen veröffentlichen. Wie funktioniert eine solche selbstorganisierte Publikationspraxis? Welche Probleme und Potenziale gehen mit ihr einher? – Wir werden diese Fragen entlang eigener Erfahrungen als Herausgebende einer verlagsunabhängigen Open-Access-Zeitschrift zu beantworten versuchen.

description: We report spin-polarized inelastic neutron scattering of the dynamical structure factor of the conical magnetic helix in the cubic chiral magnet MnSi. We find that the spectral weight of spin-flip scattering processes is concentrated on single branches for wavevector transfer parallel to the helix axis as inferred from well-defined peaks in the neutron spectra. In contrast, for wavevector transfers perpendicular to the helix the spectral weight is distributed among different branches of the magnon band structure as reflected in broader features of the spectra. Taking into account the effects of instrumental resolution, our experimental results are in excellent quantitative agreement with parameter-free theoretical predictions. Whereas the dispersion of the spin waves in MnSi appears to be approximately reciprocal at low energies and small applied fields, the associated spin-resolved spectral weight displays a pronounced non-reciprocity that implies a distinct non-reciprocal response in the limit of vanishing uniform magnetization at zero magnetic field.

description: We investigate fractional Brownian motion with a microscopic random-matrix model and introduce a fractional Langevin equation. We use the latter to study both sub- and superdiffusion of a free particle coupled to a fractal heat bath. We further compare fractional Brownian motion with the fractal time process. The respective mean-square displacements of these two forms of anomalous diffusion exhibit the same power-law behavior. Here we show that their lowest moments are actually all identical, except the second moment of the velocity. This provides a simple criterion which enables to distinguish these two non-Markovian processes.

Spirituality and mental health – investigating the association between spiritual attitudes and psychosomatic treatment outcomes
Creators: name: Hinterberger, Thilo

Publisher: name: Universität Regensburg
Year: 2025
Subjects: subject: spirituality, mental health, psychosomatic medicine, questionnaire, treatment outcome
subject: 610 Medizin

description: Background: The relationship between spirituality and mental health has garnered attention, fostering overall well-being. Spirituality, posited as a protective factor, may enhance resilience and provide meaning, thus benefiting mental health. This study aims to identify spirituality-associated factors influencing clinical outcomes in psychosomatic inpatients and validate the Transpersonal Spirituality Inventory (TSI).

Methods: The study involved 4952 psychosomatic inpatients completing the Transpersonales Vertrauen (TPV) and 7739 patients completing the TSI, with assessments conducted at admission and discharge. Additional instruments included the ISR for symptom rating and the LK-18 for life skills. Factor analysis and Spearman’s rank correlation were used to evaluate the validity of TSI and the relationship between spirituality and clinical outcomes.

Results: Factor analysis confirmed the TSI’s two-factor structure: “centered connectedness” (F1) and “transcendent orientation” (F2), with satisfactory internal consistency (Cronbach’s α = 0.824 for F1 and 0.644 for F2). Higher spirituality levels, particularly in transpersonal trust and centered connectedness, correlated with lower depression and psychosomatic symptoms (ISR). Although these correlations were generally weak, significant associations were found between spirituality and life competences, particularly in meaning, belief, and values (r = .595 for TPV and .598 for TSI F1).

Conclusion: Despite correlations between psychosomatic health and spirituality as measured with TPV and TSI were rather small several spirituality items could be identified which seem to have a prominent connection to the diagnosis and development of psychosomatic health. Specific spiritual attitudes, such as access to inner stillness and connection to a greater whole, were linked to positive treatment responses and reduced symptom burden. These findings suggest potential benefits in incorporating spirituality into psychosomatic treatments, though its complex and multifaceted nature warrants further investigation.

description: Background: Many patients at high cardiovascular risk do not reach targets for low-density lipoprotein cholesterol (LDL-C) and blood pressure (BP). Depression is a frequent comorbidity in these patients and contributes to poor medication adherence. Objective: The aim of this study was to elucidate the associations between adherence to lipid- and BP-lowering drugs, the diagnosis of depression, and the control of LDL-C and BP. Patients and methods: This study was conducted as multicenter, single-visit cross-sectional study in Germany. Adherence was assessed by the Morisky Medication Adherence Scale-8 (MMAS-8), and depression was assessed as documented in the patient chart. Results: A total of 3,188 ambulatory patients with hypercholesterolemia (39.8%), stable coronary artery disease (CAD; 7.4%), or both (52.9%) were included. Patients had a history of myocardial infarction (30.8%), diabetes (42.0%), were smokers (19.7%), and 16.1% had the investigator-reported diagnosis of depression. High or moderate adherence to lipid-lowering medication compared to low adherence was associated with lower LDL-C levels (105.5±38.3 vs 120.8±42.4 mg/dL) and lower BP (systolic BP 133.4±14.5 vs 137.9±13.9 mmHg, diastolic BP 78.3±9.6 vs 81.8±9.6 mmHg) and with a higher proportion of patients achieving the guideline-recommended LDL-C (16.9% vs 10.1%) and BP target (52.2% vs 40.8%, all comparisons P<0.0001). Adherence was worse in patients with depression. Correspondingly, patients with depression showed higher LDL-C levels, higher BP, and a lower probability of achieving the LDL-C and BP goal. Medication adherence correlated between BP- and lipid-lowering medications. Conclusion: Self-reported medication adherence can be easily obtained in daily practice. A low adherence and the diagnosis of depression identify patients at risk for uncontrolled LDL-C and BP who likely benefit from intensified care.

description: Quite recently, Izmailian and Hu [Phys. Rev. Lett. 86, 5160 (2001)] studied the finite-size correction terms for the free energy per spin and the inverse correlation length of the critical two-dimensional Ising model. They obtained the universal amplitude ratio for the coefficients of two series. In this study we give a simple derivation of this universal relation; we do not use an explicit form of series expansion. Moreover, we show that the Izmailian and Hu's relation is reduced to a simple and exact relation between the free energy and the correlation length. This equation holds at any temperature and has the same form as the finite-size scaling.

description: A strong link exists between iron oxides and soil organic carbon (SOC). However, the role of iron oxides in the preservation of SOC in agricultural soil remains poorly understood. In this study, we comprehensively examined the concentration, molecular composition and biological sources of iron oxide‐bound organic carbon (Fe‐bound OC) in arable soils collected from 12 sites in central and east China. The results indicated that 6.2 ~ 31.2% of the SOC was bound to iron oxides in agricultural soil and that the binding mechanisms varied from adsorption in most soils to coprecipitation in those with a large content of organic carbon. The distribution of Fe‐bound OC showed no clear variation in relation to site, but Fe‐bound OC reached a peak in soils with an annual mean temperature of 16.4°C. Correlation analysis demonstrated that TOC might be the main determinant for the amount of Fe‐bound OC and that the binding mechanism is influenced by both TOC and the active Fe ratio. Comprehensive studies of C/N, 13C isotope and synchrotron radiation‐based Fourier transform infrared (SR‐FTIR) spectroscopy showed that iron oxides selectively protected plant‐derived aliphatic compounds and polysaccharides in agricultural soil. This study revealed the quantitative characterization, biological sources and molecular composition of Fe‐bound OC in arable soils, which provides useful information for evaluating and managing the global C cycle under the framework of climate change.

description: Two-dimensional group-VI transition metal dichalcogenide semiconductors, such as MoS2, WSe2 and others, exhibit strong light-matter coupling and possess direct band gaps in the infrared and visible spectral regimes, making them potentially interesting candidates for various applications in optics and optoelectronics. Here, we review their optical and optoelectronic properties with emphasis on exciton physics and devices. As excitons are tightly bound in these materials and dominate the optical response even at room-temperature, their properties are examined in depth in the first part of this article. We discuss the remarkably versatile excitonic landscape, including bright, dark, localized and interlayer excitons. In the second part, we provide an overview on the progress in optoelectronic device applications, such as electrically driven light emitters, photovoltaic solar cells, photodetectors and opto-valleytronic devices, again bearing in mind the prominent role of excitonic effects. We conclude with a brief discussion on challenges that remain to be addressed to exploit the full potential of transition metal dichalcogenide semiconductors in possible exciton-based applications.

description: Starting from a microscopic t-J like model and a SU(2) spin-charge separation ansatz, a relativistic continuum gauge lagrangian is obtained in the vicinity of a nodal point of the Fermi surface. The excitations in the pseudogap phase are described by topological excitations in the dual model which has a Z_2 global symmetry due to the effect of instantons. Confinement of spinon and holons emerge from this picture. The adjoint and fundamental strings are associated with stripes. As the spin gap decreases a local Z_2 symmetry emerges.

description: In this paper, we study properties of effective impedance of finite electrical networks and calculate the effective impedance of a finite ladder network over an ordered field. Moreover, we consider two particular examples of infinite ladder networks (Feynman's network or LC-network and CL-network, both with zero on infinity) as networks over the ordered Levi-Civita field. We show, that effective impedances of finite LC-networks converge to the limit in order topology of Levi-Civita field, but the effective impedances of finite CL-networks do not converge in the same topology.

description: Die Einleitung des Tagungsbands Spatial Metaphors: Ancient Texts and Transformations umfasst zwei Abschnitte: Der erste Teil enthält vorbereitende Anmerkungen zur Metapherntheorie und versucht, durch die Klassifizierung anhand der Kriterien von Spezifität (specificity) und Umfang (extent) eine theoretische Struktur für die Untersuchung von Raummetaphern zu erarbeiten. Der Zugang, der dieser Typologie zugrundeliegt, steht in der Tradition der Theorie konzeptueller Metaphern von Lakoff und Johnson. Der zweite Abschnitt bietet eine kurze Übersicht und Zusammenfassung der einzelnen Beiträge des Bands (von denen nicht alle auf die Theorie konzeptueller Metaphern zurückgreifen) mit besonderer Berücksichtigung der Fragestellung, wie sich die untersuchten Metaphern zu der eingangs vorgestellten Struktur verhalten. Dabei wird deutlich, dass, obgleich die Möglichkeit einer formalen Klassifikation von Raummetaphern besteht, jede philologische Untersuchung und Interpretation immer die entsprechenden Kontexte miteinbeziehen muss und dabei nicht von abstrakten theoretischen Metaphermodellen, sondern den Texten selbst ihren Ausgang nehmen muss.

description: Deviations from standard electroweak physics arise in the framework of a Randall-Sundrum model, with matter and gauge fields in the bulk and the Higgs field localized on the TeV brane. We focus in particular on modifications associated with the weak mixing angle. Comparison with the electroweak precision data yields a rather stringent lower bound of about 10 TeV on the masses of the lowest Kaluza-Klein excitation of the W and Z bosons. With some optimistic assumptions the bound could be lowered to about 7 TeV.

description: Unsere kognitive Fähigkeit, die Welt um uns zu interpretieren, beruht weitgehend auf Metapher und Metonymie. Beide erlauben es uns, ausgehend von den Prinzipien von Ähnlichkeit und Kontiguität zwischen Konzepten, Beziehungen zwischen Unbekanntem und Bekanntem, Entlegenem und Naheliegendem, Unsichtbarem und Sichtbarem zu sehen. Die Atomisten schufen solch eine Ähnlichkeit oder Analogie zwischen der sichtbaren griechischen Schrift und der unsichtbaren Welt der Atome. Zeitgenössische Biologen nutzen dieses Denkmodell weiterhin in Bezug auf molekulare Biologie. Durch vielfältige Beispiele von der Bibelexegese bis zur Welt der Naturwissenschaft und Technik wird die weite Verbreitung solcher Denkmodelle (und teilweise auch ihre Zeitgebundenheit) aufgezeigt. In der Vergangenheit bestand ein großes Problem in der Hauptströmung europäischen Denkens, die auf Beziehungen zwischen Wörten statt zwischen Konzepten, wie im Fall der Metapher, beharrte.
Interaction Of Electrons With Spin Waves In The Bulk And In Multilayers

description: The exchange interaction between electrons and magnetic spins is considerably enhanced near interfaces, in magnetic multilayers. As a result, a dc current can be used to generate spin oscillations. We review theory and experimental evidence. The s-d exchange interaction causes a rapid precession of itinerant conduction-electron spins s around the localized spins S of magnetic electrons. Because of the precession, the time-averaged interaction torque between s and S vanishes. An interface between a magnetic layer and a spacer causes a local coherence between the precession phases of differnt electrons, within 10 nm from the interface, and restores the torque. Also, a second magnetic layer with pinned S is used to prepare s in a specific direction. the current-induced drive torque of s on S in the active layer may be calculated from the spin current (Slonczewski) or from the spin imbalance Delta-mu (Berger). Spin current and Delta-mu are proportional to each other, and can arise from Fermi-surface translation, as well as from expansion/contraction.

description: Diese Studie analysiert einige Weisheitstexte aus dem ägyptischen Neuen Reich und der Dritten Zwischenzeit (1550–712 BC), um die rhetorische sowie kommunikative Anwendungen von räumlichen Metaphern zu skizzieren. Unser Verständnis altägyptischer Rhetorik wird dadurch verstärkt: Wir sehen, zum Beispiel, dass die räumlichen Metaphern (insbesondere die Wegmetaphern) sich vermehren und expliziter werden wobei die rhetorische Qualität des Textes ebenso zunimmt – oder anders ausgedrückt, dass die enumerative Weisheitsgattung zunehmend von den Aufrufen der Schultexte beeinflusst wird.

description: Many research questions can be answered quickly and efficiently using data already collected for previous research. This practice is called secondary data analysis (SDA), and has gained popularity due to lower costs and improved research efficiency. In this paper we propose DFS, a file system to standardize the metadata representation of datasets, and DDU, a scalable architecture based on DFS for semi-automated metadata generation and data recommendation on the cloud. We discuss how DFS and DDU lays groundwork for automatic dataset aggregation, how it integrates with existing data wrangling and machine learning tools, and explores their implications on datasets stored in digital libraries.

QSO redshift estimates from optical, near-infrared and ultraviolet colours

description: A simple estimate of the photometric redshift would prove invaluable to forthcoming continuum surveys on the next generation of large radio telescopes, as well as mitigating the existing bias towards the most optically bright sources. While there is a well known correlation between the near-infrared K-band magnitude and redshift for galaxies, we find the K-z relation to break down for samples dominated by quasi-stellar objects (QSOs). We hypothesise that this is due to the additional contribution to the near-infrared flux by the active galactic nucleus (AGN), and, as such, the K-band magnitude can only provide a lower limit to the redshift in the case of active galactic nuclei, which will dominate the radio surveys. From a large optical dataset, we find a tight relationship between the rest-frame (U-K)/(W2-FUV) colour ratio and spectroscopic redshift over a sample of 17,000 sources, spanning z ~ 0.1 - 5. Using the observed-frame ratios of (U K)/(W2-FUV) for redshifts of z > 1, (I-W2)/(W3-U) for 1 < z < 3 and (I-W2.5)/(W4-R) for z > 3, where W2.5 is the 8.0 micron magnitude and the appropriate redshift ranges are estimated from the W2 (4.5 micron) magnitude, we find this to be a robust photometric redshift estimator for quasars. We suggest that the rest-frame U-K colour traces the excess flux from the AGN over this wide range of redshifts, although the W2-FUV colour is required to break the degeneracy.

description: Aristoteles konzipierte das Substantiv metaphora (wörtlich „Transfer“) als das Ergebnis eines sprachlichen und kognitiven Übertragungsprozesses, der einen Vergleich oder eine Analogie zwischen zwei materiellen oder geistigen Elementen voraussetzt. Dieser Metapherbegriff erlaubt jedoch nicht, die Auswirkung von semantischen Mischungen solcher Elemente zu erfassen. Dies zeigt der Begriff kratēr (wörtlich „Misch-Objekt“) in der griechischen Dichtung, wo er als Emblem und nicht notwendigerweise als Metapher für verschiedene Formen räumlicher und nicht-räumlicher Übertragung gebraucht wird, aber auch für Mischungen, die im Symposion stattfinden.

description: Accurate platform localization is an integral component of most robotic systems. As these robotic systems become more ubiquitous, it is necessary to develop robust state estimation algorithms that are able to withstand novel and non-cooperative environments. When dealing with novel and non-cooperative environments, little is known a priori about the measurement error uncertainty, thus, there is a requirement that the uncertainty models of the localization algorithm be adaptive. Within this paper, we propose the batch covariance estimation technique, which enables robust state estimation through the iterative adaptation of the measurement uncertainty model. The adaptation of the measurement uncertainty model is granted through non-parametric clustering of the residuals, which enables the characterization of the measurement uncertainty via a Gaussian mixture model. The provided Gaussian mixture model can be utilized within any non-linear least squares optimization algorithm by approximately characterizing each observation with the sufficient statistics of the assigned cluster (i.e., each observation's uncertainty model is updated based upon the assignment provided by the non-parametric clustering algorithm). The proposed algorithm is verified on several GNSS collected data sets, where it is shown that the proposed technique exhibits some advantages when compared to other robust estimation techniques when confronted with degraded data quality.
