Effects of general magnetic field therapy in comprehensive medical rehabilitation on the quality of life of patients with breast cancer

BACKGROUND: The Short Form-36 (SF-36) is one of the most widely used tools to assess quality of life in breast cancer patients. According to MEDLINE, the SF-36 is used in 95.0% of research studies to assess the quality of life in various diseases. Advantages of SF-36 include wide availability, ease of use, and high validity. AIM: The aim of the study was to evaluate the effect of general magnetic field therapy in comprehensive medical rehabilitation on the quality of life parameters using a SF-36 questionnaire in breast cancer patients at 2–4 days and 1.0–1.5 months after surgery. MATERIALS AND METHODS: A randomized, placebo-controlled study was conducted in patients (n=107) after surgery for breast cancer. All patients were divided into three groups balanced by age and clinical and functional parameters, and received a course of medical rehabilitation which included individual postoperative sessions of exercise therapy (posture treatment; movement therapy with breathing, general stimulating, special, and relaxation exercises; sensorimotor training using a biofeedback simulator; individual sessions with a medical psychologist; one session of instrumental physiotherapy). Comprehensive medical rehabilitation included fluctuating current therapy in group 1 (n=35), local magnetic field therapy in group 2 (n=35), and general magnetic field therapy in group 3 (n=37). RESULTS: Analysis of quality of life parameters in the early postoperative period demonstrated effectiveness of the comprehensive physical rehabilitation program using exercise therapy, balance boards, and sessions with a psychologist in combination with one of the physical treatment options. Positive results increase patients’ confidence in the success of their rehabilitation. After providing the general magnetic field therapy in comprehensive medical rehabilitation, most of the SF-36 quality of life parameters improved, which indicates the beneficial effects of the general magnetic field on situational and personal anxiety, asthenic and vegetative manifestations, and sleep, as well as prolongation of these effects. Patients who received fluctuating current therapy as part of medical rehabilitation improved their pain index and physical function, probably due to analgesic and anti-inflammatory effects of this treatment option. CONCLUSION: Comprehensive physical rehabilitation combined with physical therapy increases the patient’s independence in daily living, self-care, and mobility.

GRADIENT ESTIMATES FOR POSITIVE EIGENFUNCTIONS OF THE $\mathcal {L}$ -OPERATOR ON CONFORMAL SOLITONS AND THEIR APPLICATIONS

Abstract We prove a local gradient estimate for positive eigenfunctions of the $\mathcal {L}$ -operator on conformal solitons given by a general conformal vector field. As an application, we obtain a Liouville type theorem for $\mathcal {L} u=0$ , which improves the one of Li and Sun [‘Gradient estimate for the positive solutions of $\mathcal Lu = 0$ and $\mathcal Lu ={\partial u}/{\partial t}$ on conformal solitons’, Acta Math. Sin. (Engl. Ser.)37(11) (2021), 1768–1782]. We also consider applications where manifolds are special conformal solitons and obtain a better Liouville type theorem in the case of self-shrinkers.

Elementary Steps of Catalytic Reactions Occurring on Metallic Alloy Nanoparticles.

Catalytic reactions running in an adsorbed overlayer on metallic alloy nanoparticles are of high interest in the context of applications in the chemical industry. The understanding of the corresponding kinetics is, however, still limited. One of the reasons of this state of the art is the interplay between adsorption and adsorbate-influenced segregation of metal atoms inside alloy nanoparticles. I scrutinize this interplay by using a generic field model of segregation and the mean-field approximation in order to describe adsorption, desorption, and elementary catalytic reactions. Under steady-state conditions, the segregation is demonstrated to be manifested in the change of the dependence of the activation energies of desorption or elementary reactions on coverage, and the sign of this change is positive. The effect of this change on the apparent reaction orders is briefly discussed as well.

Student-centred OdeL support in theology: Why? and how?

Equipping students to become future-fit graduates who are competent to survive and thrive in an increasingly liquid and complex society presents an agonising challenge to educators at institutions of higher education. It seems that student-centred support is a key requirement for the renovation of open distance higher education. ‘The complex fourth revolution world we are living in’, the current unequal and diverse student body and the need to train students in theology to be agents of positive change and transformation highlight why student-centred edu-actions are required. Suggestions on how to create opportunities for, and how to implement effective student-centred support are presented through a descriptive qualitative approach. Although this is focussed on theology students, student support is needed in all disciplines and this structure can, if successful, also be transferred to other fields in human science. Nested in the centre of the Community of Inquiry model, the triangle of effective education provides the structure and foundation for both the discipline-specific and the more general fields of the pillars of higher education. Based on the foundation of this triangle, a toolkit for student success is proposed. The toolkit forms the inner part of the triangle; referring to who the students are, how they think, reason and act, culminate in how they change and grow through education. In addition, a short learning programme for educators is proposed to assist them in adapting their tasks to the changing environment and simultaneously supporting their students.Intradisciplinary/interdisciplinary implications: Although the focus is on theology students and lecturers, both the toolkit and lecturer training programmes can be implemented for the promotion of purpose-driven and human-centred skills development and academic excellence in the larger disciplines and fields of arts, humanities, social sciences and religious studies.

Harmony search algorithm to enhance approach to permutation flow shop scheduling problem

The permutation flow-shop scheduling problem (PFSP) is one of the widely analysed and investigated problems within the general field of scheduling, as its major focus is on the allocation and sequencing of a set of jobs across a set of machines in order to minimize the makespan or satisfy other criteria. This paper further generalizes the problem to the distributed permutation flow-shop scheduling problem (DPFSP), namely in a manufacturing system with multiple factories, where every factory employs identical machines; with the objective of achieving the least makespan at the worst factory in terms of processing time. We resolve the issue through a Harmony Search Algorithm (HSA), a metaheuristic model developed from the musical harmonisation concept, together with constraint programming techniques, including interval variables and non-adjacent constraints. The problemsolving algorithm incorporates a lower bound estimation heuristic for efficiently directing the search in the right possible solution zone. Performance evaluation on both the small benchmark and the large benchmark data set showed the ability of the HSA to perform the different assignment in various problem scenarios that include the different number of jobs, machines and factories to support them. Comparisons with the best-known values established the performance of the HSA algorithm in identifying high quality solutions for the PFSP in less computation time.

Spiritual Intelligence and Spiritual Care in Nursing Practice: A Bibliometric Review

Spiritual intelligence (SI) has recently gained traction in various fields, including nursing. Given the increasing emphasis on patient-centred care and the holistic well-being of patients and nurses, SI is particularly relevant in nursing practice. A bibliometric analysis of recent publications (2014–2024) in the field helps synthesise and evaluate the existing research on SI in the general field of nursing, identify literature gaps, suggest future research directions and raise awareness of the importance of SI in nursing practice. The present study reports bibliometric data (n = 461) from the Scopus database on SI, spiritual quotient and spiritual care in nursing and health care. The data are analysed using MS Excel and VOSviewer software. The publications’ trend analysis revealed a significant increase in SI-related publications since 2015. The study presents top-cited articles. Journal of Religion and Health was found to be a prominent journal with the maximum number of publications, and Sage was found to be the top publisher of journals with articles on SI. Network visualisation reveals central figures such as Wilfred McSherry, Trove Giske, Elizabeth Johnston Taylor, Fiona Timmins, Silvia Caldeira and Linda Ross as key researchers in the field. The United States and Iran have the most substantial connections of authors publishing on SI. This study reveals an increasing interest in SI and care within nursing research, confirming its growing significance in the field. By reporting areas where research on SI in nursing remains underdeveloped, the study paves the way for the development of new or updated curricula in nursing programs. The study can guide faculty development initiatives by highlighting the importance of SI and providing resources for educators to incorporate these concepts into their teaching. This study presents specific research questions to address these knowledge gaps. Future studies which can address these questions will enrich nursing education and practice, leading to improved patient outcomes and enhanced nurse well-being using the full potential of SI in nursing practice.

A generic random field approach for stratification uncertainty quantification

Geological uncertainty is a crucial factor in the reliability design of geotechnical structures, necessitating advanced probabilistic approaches for robust subsurface stratification and uncertainty quantification. However, the spatial existence of geological formations at a specific location is indeed a nominal categorical variable. Unlike the spatial variability of soil properties that has been widely addressed using random field theory or geostatistics, quantifying the spatial correlations of formation existence poses unique challenges. In this study, a generic framework for geological uncertainty quantification is proposed. The spatial existence of each formation is modeled with individual latent random fields, such that the spatial correlation strength of formation existence can be defined in a consistent manner as that in geotechnical random fields. Moreover, an effective distance metric is introduced to accommodate spatial correlations within a distorted random field, allowing for the incorporation of stratigraphic dip naturally. The latent random fields are subsequently input into the generalized linear mixed model (GLMM) to derive the probabilistic distribution of formation existence in the form of discrete random fields. The simulation framework is further formulated as a Bayesian inference problem to incorporate existing information from borehole records of a site. The proposed formulation offers great flexibility and versatility in simulating various complex stratigraphic configurations, which is demonstrated through a hypothetical case study with an inter-layer and a real case study in Perth, West Australia. This study advances rigorous quantification of stratification uncertainty, facilitating more reliable geotechnical design and risk assessment in complex geological environments.

Soft-photon theorem for pion-proton elastic scattering revisited

We discuss the reactions πp→πp and πp→πpγ from a general quantum field theory (QFT) point of view, describing these reactions in QCD and lowest relevant order of electromagnetism. We consider the pion-proton elastic scattering both off shell and on shell. The on-shell amplitudes for π±p→π±p scattering are described by two invariant amplitudes, while the off-shell amplitudes contain eight invariant amplitudes. We study the photon emission amplitudes in the soft-photon limit where the center-of-mass photon energy ω→0. The Laurent expansion in ω of the π±p→π±pγ amplitudes is considered and the terms of the orders ω−1 and ω0 are derived. These terms can be expressed by the on-shell invariant amplitudes and their partial derivatives with respect to s and t. The pole term ∝ω−1 in the amplitudes corresponds to Weinberg’s soft-photon theorem and is well known from the literature. We derive the next-to-leading term ∝ω0 using only rigorous methods of QFT. We give the relation of the Laurent series for π0p→π0pγ and Low’s soft-photon theorem. Our formulas for the amplitudes in the limit ω→0 are valid for photon momentum k satisfying k2≥0, k0=ω≥0, that is, for both real and virtual photons. Here we consider a limit where with ω→0 we have also k2→0. We discuss the behavior of the corresponding cross sections for π−p→π−pγ with respect to ω for ω→0. We consider cross sections for unpolarized as well as polarized protons in the initial and final states. Published by the American Physical Society 2024

OLUFF: a novel set of ground and excited state force field parameters of the emitting oxyluciferin species.

The modeling of the bioluminescent system of fireflies is key to understand the binding mode of the oxyluciferin/luciferase complex and its photophysical properties with the aim of developing high-efficiency devices and techniques. In this work, we present the OLUFF force field, which is able to describe the interactions to sample the conformational space of the four possible oxyluciferin emitters in both ground and excited state. This force field has been parameterized to reproduce quantum mechanical (QM) energies and geometrical parameters. Moreover, it has been validated by comparing probability distribution functions, minimized structures, infrared spectra and normal mode analysis obtained from OLUFF-based molecular dynamic (MD) simulations with their QM counterparts. Additionally, ground state simulations have also been performed using the general amber force field (GAFF) and compared with the OLUFF. It has been demonstrated that the OLUFF not only reproduces well the QM properties, but also improves the results from the GAFF.

Supergeometric quantum effective action

Supergeometric quantum field theories (SG-QFTs) are theories that go beyond the standard supersymmetric framework, since they allow for general scalar-fermion field transformations on the configuration space of a supermanifold, without requiring an equality between bosonic and fermionic degrees of freedom. After revisiting previous considerations, we extend them by calculating the one-loop effective action of minimal SG-QFTs that feature nonzero fermionic curvature in two and four spacetime dimensions. By employing an intuitive approach to the Schwinger–DeWitt heat-kernel technique and a novel field-space generalized Clifford algebra, we derive the ultraviolet structure of characteristic effective-field-theory (EFT) operators up to four spacetime derivatives that emerge at the one-loop order and are of physical interest. Upon minimizing the impact of potential ambiguities due to the so-called multiplicative anomalies, we find that the EFT interactions resulting from the one-loop supergeometric effective action are manifestly diffeomorphically invariant in configuration space. The extension of our approach to evaluating higher loops of the supergeometric quantum effective action is described. The emerging landscape of theoretical and phenomenological directions for further research of SG-QFTs is discussed. Published by the American Physical Society 2024

The slice spectral sequence for a motivic analogue of the connective K(1)$K(1)$‐local sphere

AbstractWe compute the 2‐adic effective slice spectral sequence (ESSS) for the motivic stable homotopy groups of , a motivic analogue of the connective ‐local sphere over prime fields of characteristic not two. Together with the analogous computation over algebraically closed fields, this yields information about the motivic ‐local sphere over arbitrary base fields of characteristic not two. To compute the spectral sequence, we prove several results that may be of independent interest. We describe the ‐differentials in the slice spectral sequence in terms of the motivic Steenrod operations over general base fields, building on analogous results of Ananyevskiy, Röndigs, and Østvær for the very effective cover of Hermitian K‐theory. We also explicitly describe the coefficients of certain motivic Eilenberg–MacLane spectra and compute the ESSS for the very effective cover of Hermitian K‐theory over prime fields.

A head-to-head comparison of MM/PBSA and MM/GBSA in predicting binding affinities for the CB1 cannabinoid ligands.

The substantial increase in the number of active and inactive-state CB1 receptor experimental structures has provided opportunities for CB1 drug discovery using various structure-based drug design methods, including the popular end-point methods for predicting binding free energies-Molecular Mechanics/Poisson-Boltzmann Surface Area (MM/PBSA) and Molecular Mechanics/Generalized Born Surface Area (MM/GBSA). In this study, we have therefore evaluated the performance of MM/PBSA and MM/GBSA in calculating binding free energies for CB1 receptor. Additionally, with both MM/PBSA and MM/GBSA being known for their highly individualized performance, we have evaluated the effects of various simulation parameters including the use of energy minimized structures, choice of solute dielectric constant, inclusion of entropy, and the effects of the five GB models. Generally, MM/GBSA provided higher correlations than MM/PBSA (rMM/GBSA = 0.433 - 0.652 vs. rMM/PBSA = 0.100 - 0.486) regardless of the simulation parameters, while also offering faster calculations. Improved correlations were observed with the use of molecular dynamics ensembles compared with energyminimized structures and larger solute dielectric constants. Incorporation of entropic terms led to unfavorable results for both MM/PBSA and MM/GBSA for a majority of the dataset, while the evaluation of the various GB models exerted a varying effect on both the datasets. The findings obtained in this study demonstrate the utility of MM/PBSA and MM/GBSA in predicting binding free energies for the CB1 receptor, hence providing a useful benchmark for their applicability in the endocannabinoid system as well as other G protein-coupled receptors. The study utilized the docked dataset (Induced Fit Docking with Glide XP scoring function) from Loo et al., consisting of 46 ligands-23 agonists and 23 antagonists. The equilibrated structures from Loo et al. were subjected to 30ns production simulations using GROMACS 2018 at 300K and 1atm with the velocity rescaling thermostat and the Parinello-Rahman barostat. AMBER ff99SB*-ILDN was used for the proteins, General Amber Force Field (GAFF) was used for the ligands, and Slipids parameters were used for lipids. MM/PBSA and MM/GBSA binding free energies were then calculated using gmx_MMPBSA. The solute dielectric constant was varied between 1, 2, and 4 to study the effect of different solute dielectric constants on the performance of MM/PB(GB)SA. The effect of entropy on MM/PB(GB)SA binding free energies was evaluated using the interaction entropy module implemented in gmx_MMPBSA. Five GB models, GBHCT, GBOBC1, GBOBC2, GBNeck, and GBNeck2, were evaluated to study the effect of the choice of GB models in the performance of MM/GBSA. Pearson correlation coefficients were used to measure the correlation between experimental and predicted binding free energies.

Influence of multimodal fiber distribution on the permeability of fibrous media

This article deals with the impact of fiber size distribution on the permeability of nonwoven fibrous media, a major issue in the general field of filtration. The conventional method to determine the permeability of nonwoven fibrous media involves equating complex fibrous media with structures composed of a single equivalent fiber diameter. Based on numerical simulations of flow through tridimensional structures with polymodal and polydisperse fiber size distributions, we proposed a new equivalent diameter. In conjunction with a packing density function, the approach is compared to experimental data and simulations available in the scientific literature and shows better permeability predictions than other existing models for a wide range of solid volume fractions (1 % to 20 %) and fiber diameters (1.5 µm to 30 µm). This predictive model of permeability is an essential step in developing a decision-making tool for the design of fibrous media.

ASW^2DF: Census of the obscured star formation in a galaxy cluster in formation at z=2.2

We report the results of the deep and wide Atacama Large Millimeter/submillimeter Array (ALMA) 1.2\,mm mapping of the Spiderweb protocluster at $z=2.16$. The observations were divided into six contiguous fields covering a survey area of 19.3\,arcmin$^2$. With sim 13h of on-source time, the final maps in the six fields reach the 1sigma rms noise in a range of $40.3-57.1\ at a spatial resolution of $0 By using different source extraction codes and careful visual inspection, we detected 47 ALMA sources at a significance higher than 4sigma . We constructed the differential and cumulative number counts down to $ after the correction for purity and completeness obtained from Monte Carlo simulations. The ALMA 1.2\,mm number counts of dusty star-forming galaxies (DSFGs) in the Spiderweb protocluster are overall two times that of general fields, with some regions showing even higher overdensities (more than a factor of three). This is consistent with the results from previous studies over a larger scale using single-dish instruments. Comparison of the spatial distributions between different populations indicates that our ALMA sources are likely drawn from the same distribution as CO(1-0) emitters from the COALAS large program but are distinct from that of Halpha emitters. The cosmic star formation rate density of the ALMA sources is consistent with previous results (e.g., LABOCA 870\,mu m observations) after accounting for the difference in volume. We show that molecular gas masses estimates from dust measurements are not consistent with the ones derived from CO(1-0) and thus have to be taken with caution. The multiplicity fraction of single-dish DSFGs is higher than that of the field. Moreover, two extreme concentrations of ALMA sources were found on the outskirts of the Spiderweb protocluster, with an excess of more than 12 times that of the general fields. These results indicate that the ALMA-detected DSFGs are supplied through gas accretion along filaments and are triggered by intense star formation by accretion shocks before falling into the cluster center. The identified two galaxy groups are likely falling into the protocluster center and will trigger new merger events eventually, as indicated in simulations.

On Weil–Stark elements, I: Construction and general properties

AbstractWe construct a canonical family of elements in the reduced exterior powers of unit groups of global fields and investigate their detailed arithmetic properties. We then show that these elements specialise to recover the classical theory of cyclotomic elements in real abelian fields and also have connections to the theory of non‐commutative Euler systems for over general number fields.

Geometric main conjectures in function fields

Abstract We prove an equivariant main conjecture in Iwasawa theory along any rank-one, sign-normalized Drinfeld modular, split-at-∞ Iwasawa tower of a general function field of characteristic 𝑝, for the Iwasawa modules recently considered by Greither and Popescu in their proof of the classical equivariant main conjecture along the (arithmetic) cyclotomic Iwasawa tower. As a consequence, we prove an equivariant main conjecture for a projective limit of certain Ritter–Weiss type modules, along the same Drinfeld modular Iwasawa towers. This generalizes the results of Anglès, Bandini, Bars, Coscelli and Longhi for the split-at-∞ piece of the Iwasawa towers considered in their work, and refines the results by Greither and Popescu.

Estimate of in-band eddy current effect in space gravitational wave detection

Abstract In space detection of gravitational waves (GWs), the presence of a low-frequency varying magnetic field will generate eddy currents in the test mass, resulting in a varying magnetic moment. This magnetic moment will couple with a constant magnetic field gradient, producing residual acceleration within the frequency band of GW detection, causing the test mass to deviate from the free-falling mode. However, this effect has not yet been studied clearly in the noise budget for TianQin and LISA Pathfinder since the constant DC magnetic susceptibility was applied to quantify the varying magnetic moment. This paper utilizes the parameter of alternating current (AC) magnetic susceptibility to define this process, and further analyzes and evaluates the effect. In a general magnetic field environment, the contribution of this effect to TianQin acceleration noise reaches 20\% from 0.1 mHz to 3 mHz. The contribution to LISA noise is less than 10\% from $10^{-4}$ to 0.1 Hz, and less than 10\% below $10^{-4}$ Hz. This effect does not have a potential limit on LISA low-frequency science down to 20 $\mu$Hz [Phys. Rev. Lett. 120, 061101 (2018)].

Women, Horses and Dogs. A Reading of Sorana Gurian's Novel from the Animal Studies Perspective

Sorana Gurian's proverbial passion for pets, almost unnoticed in Romanian literary history, deserves a careful analysis, especially because it was directly recognized as and even constituted the foundation of some substantial pages of memoir or fiction prose, written by this cosmopolite, intriguing, and spectacular author, who linked her biographical existence to several Moldavian, Romanian and French spaces. Animals have a completely exceptional importance especially in the novel "The days never come back" (1945) – where the number of animal references is huge (compared to any other Romanian fictional prose, regardless of the era in which they were written). The text contains over two hundred references to dogs and their equivalents from the general semantic field (puppy, whelp), or from the particular one (basset, greyhound, borzoi, fox, etc.), over a hundred references to horses and several hundred other references to cats, rodents (mice, voles, rats, ferrets), birds (from swallows or sparrows to eagles) and insects of various kinds (from crickets to dragonflies). Of all these species, dogs and horses – by far, the protagonists' (Vivian, Ann and her father, nicknamed the Chief) favorites – are frequently particularized even nominally, because from the perspective of the doctor's extended family, they are true friends and communication partners, with rights sometimes superior to servants, acquaintances, or human friends. Far from being perceived as fictional ”commodity objects” or simple tools, used only to build or furnish the narrative world, animals are integrated, to varying degrees, in the families of main characters, they accompany, silently but expressively, their steps – either as partners with equal rights, either as identity doubles or complements – and even reflect, metonymically, the human's narrative evolution. Starting from these premises, my study (which combines elements of gender, trauma, and animal studies) will analyze both the various functions of the numerous elements of bestiary and animal characters, and the provocative stakes of their narrative valorization.
