description: The Tully-Fisher relation (TFR) expresses the connection between rotating galaxies and the dark matter haloes they inhabit, and therefore contains a wealth of information about galaxy formation. We construct a general framework to investigate whether models based on halo abundance matching are able to reproduce the observed stellar mass TFR and mass-size relation (MSR), and use the data to constrain galaxy formation parameters. Our model tests a range of plausible scenarios, differing in the response of haloes to disc formation, the relative angular momentum of baryons and dark matter, the impact of selection effects, and the abundance matching parameters. We show that agreement with the observed TFR puts an upper limit on the scatter between galaxy and halo properties, requires weak or reversed halo contraction, and favours selection effects that preferentially eliminate fast-rotating galaxies. The MSR constrains the ratio of the disc to halo specific angular momentum to be approximately in the range 0.6-1.2. We identify and quantify two problems that models of this nature face. (1) They predict too large an intrinsic scatter for the MSR, and (2) they predict too strong an anticorrelation between the TFR and MSR residuals. We argue that resolving these problems requires introducing a correlation between stellar surface density and enclosed dark matter mass. Finally, we explore the expected difference between the TFRs of central and satellite galaxies, finding that in the favoured models this difference should be detectable in a sample of ~700 galaxies.

description: Non-invasive ventilation is often unable to provide sufficient respiratory support for very premature infants at birth. While airway obstruction is thought to be a major reason for this failure, the site of obstruction is unknown. In the current thesis, we have investigated whether laryngeal closure at birth is a major cause of airway obstruction and factors influencing laryngeal activity in preterm rabbit kittens.

description: We present Gemini Planet Imager (GPI) observations of AU Microscopii, a young M dwarf with an edge-on, dusty debris disk. Integral field spectroscopy and broadband imaging polarimetry were obtained during the commissioning of GPI. In our broadband imaging polarimetry observations, we detect the disk only in total intensity and find asymmetries in the morphology of the disk between the southeast and northwest sides. The southeast side of the disk exhibits a bump at 1$''$ (10 AU projected separation) that is three times more vertically extended and three times fainter in peak surface brightness than the northwest side at similar separations. This part of the disk is also vertically offset by 69$\pm$30 mas to the northeast at 1$''$ when compared to the established disk mid-plane and consistent with prior ALMA and Hubble Space Telescope/STIS observations. We see hints that the southeast bump might be a result of detecting a horizontal sliver feature above the main disk that could be the disk backside. Alternatively when including the morphology of the northwest side, where the disk mid-plane is offset in the opposite direction $\sim$50 mas between 0$.''$4 and 1$.''$2, the asymmetries suggest a warp-like feature. Using our integral field spectroscopy data to search for planets, we are 50% complete for $\sim$4 $M_\mathrm{Jup}$ planets at 4 AU. We detect a source, resolved only along the disk plane, that could either be a candidate planetary mass companion or a compact clump in the disk.

The microbiome and its potential as a cancer preventive intervention
Creators: name: Bultman, Scott J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: It is becoming increasingly clear that microbiota which inhabit our body influence cancer predisposition and etiology. In addition to pathogens with oncogenic properties, our commensal and symbiotic microbiota have tumor-suppressive properties. Our diet and other environmental factors can modulate the abundance of certain members of microbial communities within our gastrointestinal tract and at other anatomical sites. Furthermore, some dietary factors are metabolized by commensal/symbiotic gut microbiota into bioactive food components believed to prevent cancer. For example, dietary fiber undergoes bacterial fermentation in the colon to yield butyrate, which is a short-chain fatty acid and histone deacetylase (HDAC) inhibitor that suppresses the viability and growth of colorectal cancer cell lines. A recent study utilizing gnotobiotic mouse models demonstrates that fiber can protect against colorectal tumorigenesis in a microbiota- and butyrate-dependent manner that involves the Warburg effect. This and other examples suggest that some of the inter-individual variation observed in epidemiology and intervention studies that have investigated associations between diet and cancer risk might be explained by differences in microbiota among the participants. Data from basic research studies also support the idea that probiotics and prebiotics could be plausible chemoprevention strategies that may be utilized to a greater extent in the future.

description: Recent developments in quantum gas microscopy open up the possibility of real-time observation of quantum many-body systems. To understand the dynamics of atoms under such circumstances, we formulate the dynamics under a real-time spatially resolved measurement and show that, in an appropriate limit of weak spatial resolution and strong atom-light coupling, the measurement indistinguishability of particles results in complete suppression of relative positional decoherence. As a consequence, quantum correlation in the multi-particle dynamics persists under a minimally destructive observation. We numerically demonstrate this for ultracold atoms in an optical lattice. Our theoretical framework can be applied to feedback control of quantum many-body systems which may be realized in subwavelength-spacing lattice systems.

description: GPR173 is a novel orphan receptor that has been found to have association with heridatary Parkinson's disease. This study aims to localize GPR173 in the zebrafish brain and to investigate its association with the dopaminergic system. GPR173 was found localized in the medial diencephalon and central nucleus of the inferior lobe and fibers in close proximity with dopaminergic fibers in the interpeduncular nucleus. Suppresion of GPR173 produced changes in the dopaminergic system however the production of a Parkinson's disease model in the zebrafish was unsuccesful. Overall, this study shows that GPR173 may modulate the dopaminergic system via an indirect mechanism.

description: We study the statistics of a tagged particle in single-file diffusion, a one-dimensional interacting infinite-particle system in which the order of particles never changes. We compute the two-time correlation function for the displacement of the tagged particle for an arbitrary single-file system. We also discuss single-file analogs of the arcsine law and the law of the iterated logarithm characterizing the behavior of Brownian motion. Using a macroscopic fluctuation theory we devise a formalism giving the cumulant generating functional. In principle, this functional contains the full statistics of the tagged particle trajectory---the full single-time statistics, all multiple-time correlation functions, etc. are merely special cases.

description: This thesis examines whether ambulant children with a neurological impairment can improve their high-level mobility skills and thereby participation rates with appropriate intervention. A literature review suggested that improvements are possible. A pilot study compared a six-week high-level mobility group to usual care. The content of the training was based on achieving the biomechanical demands of running, in a manner that was engaging and appropriate for children. The results supported the efficacy of this safe intervention in providing significant and sustained high level mobility and fitness benefits, as well as improved participation to ambulant children with a neurological impairment.

Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Study Background: Nurse–patient cultural communication is of paramount significance in countries with substantial expatriate nursing workforces, such as Saudi Arabia. Saudi Arabian hospitals are mostly staffed by foreign nurses, who constitute 73.4% of the total population of registered nurses (Ministry of Health, 2014). Aim of the Study: The purpose of this study was to explore the cultural communication barriers between non-Saudi nurses and Saudi patients when performing patient health care. Study Design: The study adopted a quantitative descriptive survey design. A convenience sampling technique was used to recruit a population of surgical nurses (n = 93) working in wards at a tertiary health care centre in Riyadh, Saudi Arabia. Descriptive statistics and non-parametric analysis (Mann-Whitney U tests) were used to analyse survey data. Results: Unfamiliarity with language or dialect and generational gap scores represented the highest cultural communication barriers, followed by other significant results that included gender difference and nurses’ burnout. Lack of continuous communication skills training and Arabic language also had an impact. Cultural communication competence was influenced by respondents not understanding the Saudi culture. Recommendations: Developing appropriate cultural communication between expatriate nurses and Saudi patients entails grasping Saudi sociocultural parameters. It is paramount that expatriate nurses intending to work in Saudi Arabia are professionally educated about Islamic Arabic cultural beliefs and communication methods. It is further suggested that Saudi patients’ perspectives on cultural obstacles in communicating with foreign nurses be explored.

In this way we obtain the spin generalization of the twisted D'Hoker- Phong and Bordner-Corrigan-Sasaki-Takasaki systems. As by product, we construct the corresponding twisted classical dynamical r-matrices and Knizhnik-Zamolodchikov-Bernard equations related to the automorphisms of the Lie algebras.

description: This research aimed to explore factors contributing to Saudi critical care nurses’ job satisfaction in Saudi Arabia. A qualitative research design was used, namely, interpretive description approach, to explore the perceptions of Saudi critical care nurses about factors influencing their job satisfaction. The data were collected through semi-structured, in-depth interviews in order to gain detailed explanation of the participants’ opinions, feelings and experiences. The target population for this research were seven Saudi nurses working in intensive care and critical care units in Mecca region, Saudi Arabia. In order to overcome the problem of national nursing shortage and turnover, along with dissatisfaction, Saudi nurses’ satisfaction in their profession is important. This is especially so in critical care units as nurses there deal with severely ill patients and stressful environment. Overall most nurses were dissatisfied with aspects of their profession. A number of factors influenced their job satisfaction such as work environment, payment, long working hours, relationships, leadership and foreign head nurses. It is hoped that findings of this study provide vision for policymakers on how nurses’ satisfaction may impact on nursing recruitment and turnover and decrease the nursing shortages
Population Effects on the Metallicity Distribution Function Derived From the Red Giant Branch

description: We have tested the reliability of the red giant branch (RGB) as a metallicity indicator accounting for observational errors as well as the complexity of star formation histories (SFHs) and chemical evolution histories observed in various stellar systems. We generate model color-magnitude diagrams (CMDs) produced with a variety of evolutionary histories and compare the resultant metallicity estimates from the colors and magnitudes of RGB stars to the true input metallicities. We include realistic models for photometric errors and completeness in our synthetic CMDs. As expected, for simple simple stellar populations dominated by old stars, the RGB provides a very accurate estimate of the modular metallicity value for a population. An error in the age of a system targeted for this type of study may produce metallicity errors of a few tenths of a dex. The size of this metallicity error depends linearly on the age error, and we find this dependence to be stronger with more precise photometry. If the population has experienced any significant star formation within the last $\sim$6 Gyr, the metallicity estimates, [M/H], derived from the RGB may be in error by up to $\sim$0.5 dex. Perhaps the most important consideration for this technique is an accurate, independent estimate of the average age for the target stellar system, especially if it is probable that a significant fraction of the population formed less than $\sim$6 Gyr ago.

description: For thirty years, the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Maternal-Fetal Medicine Units (MFMU) Network has had significant impact on clinical practice in obstetrics. The MFMU Network has conducted 50 randomized clinical trials and observational studies designed to improve pregnancy outcomes for mothers and children. Each center has a designated clinical research nurse coordinator who coordinates the day-to-day operations of each trial and leads a research team that is responsible for recruitment, and retention, of participants. Some of the lessons learned by the nurse coordinators over the past 30 years are described with examples from recent studies. Best practices that we have amassed from our experience are also described.

description: We report new correlations between ratios of band intensities of the 15-20 μm emission bands of polycyclic aromatic hydrocarbons (PAHs) in a sample of fifty-seven sources observed with Spitzer/IRS. This sample includes Large Magellanic Cloud point sources from the SAGE-Spec survey, nearby galaxies from the SINGS survey, two Galactic ISM cirrus sources and the spectral maps of the Galactic reflection nebulae NGC 2023 and NGC 7023. We find that the 16.4, 17.4 and 17.8 μm band intensities are inter-correlated in all environments. In NGC 2023 and NGC 7023 these bands also correlate with the 11.0 and 12.7 μm band intensities. The 15.8 μm band correlates only with the 15-20 μm plateau and the 11.2 μm emission. We examine the spatial morphology of these bands and introduce radial cuts. We find that these bands can be spatially organized into three sets: the 12.7, 16.4 and 17.8 μm bands; the 11.2, 15.8 μm bands and the 15-18 μm plateau; and the 11.0 and 17.4 μm bands. We also find that the spatial distribution of the 12.7, 16.4 and 17.8 μm bands can be reconstructed by averaging the spatial distributions of the cationic 11.0 μm and neutral 11.2 μm bands. We conclude that the 17.4 μm band is dominated by cations, the 15.8 μm band by neutral species, and the 12.7, 16.4 and 17.8 μm bands by a combination of the two. These results highlight the importance of PAH ionization for spatially differentiating sub-populations by their 15-20 μm emission variability.

Universal spatial correlations in the anisotropic Kondo screening cloud: analytical insights and numerically exact results from a coherent state expansion

description: We analyze the spatial correlations in the spin density of an electron gas in the vicinity of a Kondo impurity. Our analysis extends to the spin-anisotropic regime, which was not investigated in the literature. We use an original and numerically exact method, based on a systematic coherent-state expansion of the ground state of the underlying spin-boson Hamiltonian, which we apply to the computation of observables that are specific to the fermionic Kondo model. We also present an important technical improvement to the method, that obviates the need to discretize modes of the Fermi sea, and allows one to tackle the problem in the thermodynamic limit. One can thus obtain excellent spatial resolution over arbitrary length scales, for a relatively low computational cost, a feature that gives the method an advantage over popular techniques such as NRG and DMRG. We find that the anisotropic Kondo model shows rich universal scaling behavior in the spatial structure of the entanglement cloud. First, SU(2) spin-symmetry is dynamically restored in a finite domain in parameter space in vicinity of the isotropic line, as expected from poor man's scaling. We are also able to obtain in closed analytical form a set of different, yet universal, scaling curves for strong exchange asymmetry, which are parametrized by the longitudinal exchange coupling. Deep inside the cloud, i.e. for distances smaller than the Kondo length, the correlation between the electron spin density and the impurity spin oscillates between ferromagnetic and antiferromagnetic values at the scale of the Fermi wavelength, an effect that is drastically enhanced at strongly anisotropic couplings. Our results also provide further numerical checks and alternative analytical approximations for the recently computed Kondo overlaps [PRL 114, 080601 (2015)].

Biased dynamics of the miscible-immiscible quantum phase transition in a binary Bose-Einstein condensate

description: A quantum phase transition from the miscible to the immiscible phase of a quasi-one-dimensional binary Bose-Einstein condensate is driven by ramping down the coupling amplitude of its two hyperfine states. It results in a random pattern of spatial domains where the symmetry is broken separated by defects. In distinction to previous studies [J. Sabbatini et al., Phys. Rev. Lett. 107, 230402 (2011), New J. Phys. 14 095030 (2012)], we include nonzero detuning between the light field and the energy difference of the states, which provides a bias towards one of the states. Using the truncated Wigner method, we test the biased version of the quantum Kibble-Zurek mechanism [M. Rams et al., Phys. Rev. Lett. 123, 130603 (2019)] and observe a crossover to the adiabatic regime when the quench is sufficiently fast to dominate the effect of the bias. We verify a universal power law for the population imbalance in the nonadiabatic regime both at the critical point and by the end of the ramp. Shrinking and annihilation of domains of the unfavourable phase after the ramp, that is, already in the broken symmetry phase, enlarges the defect-free sections by the end of the ramp. The consequences of this phase-ordering effect can be captured by a phenomenological power law.

description: Early functional outcomes following direct anterior approach (DAA) total hip arthroplasty (THA) when compared with other approaches remains a contentious subject. This study aims to compare early clinical, functional and radiological outcomes in patients randomised between the DAA and posterior approach (PA) for THA. Between March 2014 and March 2015, 73 participants (35 DAA, 38 PA) received THA surgery at Eastern Health. Participants were evaluated pre-operatively, 2 weeks, 6 weeks and 3 months post operatively following THA surgery with multimodal outcome measures. The primary outcome measure was the Western Ontario McMasters Arthritis Index (WOMAC). Secondary measures included the Oxford Hip Score, EQ-5D, 10 metre walk test, radiological and clinical parameters. Clinical parameters analysed were length of stay, surgical time, opiate analgesic requirements, post-operative haemoglobin levels, complications, hip function and range of movement. The primary end point was time, 3 month post operatively. Statistical analysis was performed using liner mixed models and Wilcoxon Rank Sum Tests. The DAA group had longer operative times, smaller surgical wounds and higher blood loss. The length of acute hospital stay was significantly shorter for the DAA group with surgeon 1 but not for surgeon 2 or the combined results. There was no difference in total length of hospital stay between both groups. The DAA group also had a lower post-operative opiate analgesic usage 2 weeks after THA surgery. The DAA group additionally had better hip bending function 2 weeks and 6 weeks post-operatively. The DAA group had significantly weaker straight leg raise function at 2 weeks and 6 weeks post-operative time points compared to the PA group. The incidence of lateral cutaneous nerve of thigh (LCNT) neuropraxia was 83% in the DAA group. Excluding LCNT neuropraxia the other complications were not statistically significant between both groups. The study concludes that DAA THA has comparable results with PA THA. Results obtained support current evidence in the literature for both early outcomes and complications. Outcomes following DAA THA can vary between surgeons. DAA THA has benefits in improved hip bending in the early post-operative period in the absence of hip precautions. This comes at a price of weaker straight leg raise function.
Midwives' and maternity nurses' knowledge and practice in relation to breastfeeding initiation in Sohar Hospital, Oman

description: Midwives and maternity nurses have a major role in supporting babies’ health. An important strategy to achieve this includes promoting breastfeeding initiation by implementing early skin-to-skin contact (SSC) between mothers and their babies immediately after birth. The aim of this study is to investigate the knowledge and clinical practice regarding SSC and breastfeeding initiation, among a group of (national and non-national) midwives and maternity nurses working in Oman. The study used a modified version of the Newborn Feeding Ability (NFA) questionnaire and the Breastfeeding Initiation Practices (BIP) tool to survey 136 midwives and nurses. The response rate obtained was 65.4% (n=89). Findings from the study revealed that there is insufficient knowledge and lack of practice about SSC and initiation of breastfeeding. The participants reported that these practices are not implemented due to lack of time and shortage of staff in the maternity area. In particular the survey found, a total of 87.5% of respondents correctly reported that a normal full-term baby is born with an instinctive reflex ability to breastfeed effectively. Almost 75% understood that SSC helps the flow of colostrum. The majority of respondents (70.8%) reported that they always/mostly teach the mother to position and attach the baby for optimal breastfeeding. However, approximately half (49.4%) agreed/strongly agreed that there is no time after birth to allow for uninterrupted SSC until the first breastfeed and only 55.1% would always/mostly help the mother to hold her naked baby during SSC. Most respondents (59.0%) reported putting the baby on the breast for the mother. Approximately one third (31%) reported that they always/ mostly routinely suction babies soon after birth. Furthermore, less than half of respondents (45.7%) showed significant knowledge regarding the stabilisation of a newborn's blood sugar levels by SSC. The findings from this study indicate that this group of midwives and maternity nurses would benefit from additional educational support and the appropriate resources (including time) to enable them to undertake evidence-based best practice regarding breast feeding initiation.

description: Four-point measurements using a multi-tip scanning tunneling microscope (STM) are carried out in order to determine surface and step conductivities on Si(111) surfaces. In a first step, distance-dependent four-point measurements in the linear configuration are used in combination with an analytical three-layer model for charge transport to disentangle the 2D surface conductivity from non-surface contributions. A termination of the Si(111) surface with either Bi or H results in the two limiting cases of a pure 2D or 3D conductance, respectively. In order to further disentangle the surface conductivity of the step-free surface from the contribution due to atomic steps, a square four-probe configuration is applied as function of the rotation angle. In total this combined approach leads to an atomic step conductivity of $σ_\mathrm{step} = (29 \pm 9)$ $\mathrmΩ^{-1} \mathrm{m}^{-1}$ and to a step-free surface conductivity of $σ_\mathrm{surf} = (9 \pm 2) \cdot 10^{-6}\,\mathrmΩ^{-1}/\square$ for the Si(111)-(7$\times$7) surface.

title: Multi-mechanisms in proton-induced nucleon removal from 14O at 94 MeV/nucleon
Creators: name: Pohl, Thomas
Publisher: name: UNSPECIFIED
Year: 2023

description: The one-nucleon removal reaction from nuclei is a strong tool to investigate the single-particle structure. From the measurement of the residual nucleus, the orbital angular momentum of the removed nucleon can be determined. In the last decades, systematic studies on the quenching of the single-particle strength and the parallel momentum distribution of the removed nucleons have been performed. Asymmetric momentum distributions and discrepancies between measured cross sections and predictions, in particular for the deeply-bound nucleons, demonstrated, that the reaction mechanism needs to be further understood. From theoretical studies with a proton target at 100 MeV/nucleon the asymmetric distribution is attributed to stem from the interaction of the outgoing particles with the residual core nucleus. A confirmation of these theoretical results would emphasize the significance of the final state interactions. However, most of the experimental data was taken with light-ion targets and there is no data with proton targets in this incident-energy region. This is why the one-nucleon removal reaction from 14O at 94 MeV/nucleon from a hydrogen target was performed. The nucleus 14O has a large asymmetry in proton and neutron separation energies Sn - Sp = 18.55(1) MeV. The 14O secondary beam was impinged on a 2.4 mm thick solid hydrogen target. The resulting fragments were measured with the SAMURAI spectrometer. In particular, the one-nucleon removal residues 13O and 13N are of interest. Their measured inclusive cross sections and parallel momentum distributions (PMDs) are compared to theoretical calculations. Inelastic scattering, the distorted-wave impulse approximation and quantum transfer to the continuum are considered for theoretical calculations. Shell-model spectroscopic factors are applied for the comparison with the experimental data. A symmetric shape is observed for the proton removal channel, for which the (p,2p) knockout and the (p,p') inelastic channel are found contributing almost equally. The neutron removal channel exhibits a strongly asymmetric PMD, which is reproduced well by combining the results from (p,pn) knockout and (p,d) transfer. The quenching of the single-particle strength is quantified by the reduction factor Rs, which is defined by ratio of the experimental to the theoretical cross section. The reduction factors Rs are obtained and are compared to heavy-ion induced knockout and transfer reaction results. The results of this work show that the proton-induced nucleon removal from rare isotopes at energies of ~100 MeV/nucleon originates in several reaction mechanisms, including quasi-free scattering, inelastic scattering and transfer.

description: Statement of the problem: Critically ill patients in Intensive Care Units (ICUs) are faced with the challenge of surviving in a high-risk area and rely on healthcare professionals to ensure their safety and provide complex care. One way of measuring safety attitudes in the ICU is through self-reporting questionnaires. Aim: To examine attitudes to patient safety in ICU from the perspective of healthcare professionals in the Kingdom of Saudi Arabia (KSA). Method: A descriptive cross-sectional design was employed. The survey instrument - Safety Attitude Questionnaire (SAQ-ICU version) – comprised items regarding attitudes to patient safety, rating of communication and collaboration with colleagues, as well demographic questions. Results: Sixty per cent (n= 144) of the healthcare professionals from two hospitals in Taif in KSA responded. Six safety domains were scored and showed that all participants had a negative attitude towards patient safety in the two ICUs, with one ICU scoring lower in all domains. Mean scores across domains ranged from 47.14 to 70.36 on a 100-point scale, with lowest scores for the ‘perceptions of management’ domain. Leaders and bedside nurses shared similar attitudes across domains. There was a significant difference in attitudes between respiratory therapists (RTs) and nurses (F (2, 131) = 4.18, p= 0.017); there were no other significant differences between groups. Whilst communication was mostly scored as adequate, physicians rated communication high with each other and with nurses (t= 4.35, p= 0.000). Conclusion: The findings indicate that all domains need further attention. Differences between the two ICUs indicate that hospital safety culture may be an important issue for exploration in further studies.

description: Arterial and venous thrombosis are major contributors to coagulation-associated morbidity and mortality. Greater understanding of mechanisms leading to thrombus formation and stability is expected to lead to improved treatment strategies. Factor XIII (FXIII) is a transglutaminase found in plasma and platelets. During thrombosis, activated FXIII crosslinks fibrin and promotes thrombus stability. Recent studies have provided new information about FXIII activity during coagulation and its effects on clot composition and function. These findings reveal newly-recognized roles for FXIII in thrombosis. Herein, we review published literature on FXIII biology and effects on fibrin structure and stability, epidemiologic data associating FXIII with thrombosis, and evidence from animal models indicating FXIII has an essential role in determining thrombus stability, composition, and size.

description: We construct a complex linear Weil representation $ρ$ of the generalized special linear group $G={\rm SL}_*^{1}(2,A_n)$ ($A_n=K[x]/\langle x^n\rangle$, $K$ the quadratic extension of the finite field $k$ of $q$ elements, $q$ odd), where $A_n$ is endowed with a second class involution. After the construction of a specific data, the representation is defined on the generators of a Bruhat presentation of $G$, via linear operators satisfying the relations of the presentation. The structure of a unitary group $U$ associated to $G$ is described. Using this group we obtain a first decomposition of $ρ$.
Modelling uterine fibroids

description: Uterine fibroids or leiomyomas are tumors of the uterus which result from the excessive deposition of scar-like fibrous tissue into the myometrial smooth muscle. Although they are not metastatic, these growths cause chronic debilitating conditions in around 70-80% of reproductive aged women. Treatment options for this common pathology are extremely limited and often involve invasive surgery or unwanted side effects. Hence there is an urgent need for the development of better treatment options for this fibrotic disease. To test new treatments, a model system with which to investigate aspects of fibroid pathogenesis and evaluate treatment strategies is needed. Current models are limited and predominantly involve monolayer cell cultures. However such cultures do not facilitate the deposition of a collagenous extracellular matrix; a critical component of fibroids. This study investigates the potential of a technique known as macromolecular crowding, to model fibroid pathology. In this technique, large space-occupying molecules are incorporated into the culture medium, facilitating the correct processing and deposition of collagen by cells in culture. This technique has been investigated in cultures of fibroblasts and mesenchymal stem cells. However its impact on collagen deposition by myometrial smooth muscle cells is unknown. By immunocytochemical staining, the current study demonstrates that like fibroblasts, myometrial smooth muscle cells respond to crowded culture conditions by increasing production of type I collagen. This is mediated by enhanced processing of procollagen, enabling the secretion and deposition of cross-linked collagen, thus modelling the most important and symptomatic feature of fibroid pathology. Unlike monolayer cultures, the formation of an extracellular matrix in this culture system enables investigation of cell-matrix interactions. Indeed the current study suggests that the extracellular matrix produced in these cultures may interact with cell surface receptors to influence alignment of the actin cytoskeleton. By this means, these cultures may facilitate the process of mechanotransduction thought to be involved in fibroid pathogenesis. Furthermore, culturing myometrial cells under crowded conditions was shown to modulate the bioavailability of endogenous growth factors, further indicating that this methodology may prove useful in studying fibroid pathology.

description: Based on recent Lattice QCD (LQCD) results obtained at finite temperature, we discuss modeling of the hadronic phase of QCD in the framework of Hadron Resonance Gas (HRG) with discrete and continuous mass spectra. We focus on fluctuations of conserved charges, and show how a common limiting temperature can be used to constrain the Hagedorn exponential mass spectrum in different sectors of quantum number, through a matching of HRG and LQCD. For strange baryons, the extracted spectra are found to be consistent with all known and expected states listed by the Particle Data Group (PDG). The strange-mesonic sector, however, requires additional states in the intermediate mass range beyond that embodied in the database.

description: We investigate the dynamical characterization theory for periodically driven systems in which Floquet topology can be fully detected by emergent topological patterns of quench dynamics in momentum subspaces called band-inversion surfaces. We improve the results of a recent work [Zhang et al., Phys. Rev. Lett. 125, 183001 (2020)] and propose a more flexible scheme to characterize a generic class of $d$-dimensional Floquet topological phases classified by $\mathbb{Z}$-valued invariants by applying a quench along an arbitrary spin-polarization axis. Our basic idea is that by disassembling the Floquet system into multiple static subsystems that are periodic in quasienergy, a full characterization of Floquet topological phases reduces to identifying a series of bulk topological invariants for time-independent Hamiltonians, which greatly enhances the convenience and flexibility of the measurement. We illustrate the scheme by numerically analyzing two experimentally realizable models in two and three dimensions, respectively, and adopting two different but equivalent viewpoints to examine the dynamical characterization. Finally, considering the imperfection of experiment, we demonstrate that the present scheme can also be applied to a general situation where the initial state is not completely polarized. This study provides an immediately implementable approach for dynamically classifying Floquet topological phases in ultracold atoms or other quantum simulators.
