Interprofessional Collaboration Improves Quality of Life of a Young Adult With Rett Syndrome

Rett syndrome (RTT) is a genetic neurodevelopmental disease characterized by early normal development followed by regression in motor and language skills. Patients with RTT often exhibit seizure disorders, growth failure, heart and lung disorders, bruxism, and dental caries. We report on a female patient in her 20s with Rett syndrome who presented to her primary care clinic with increasing agitation and pain. This case reports describes a collaborative, interprofessional approach between medical and dental providers who work in an integrated outpatient setting. It demonstrates that interprofessional collaboration, goals of care discussions, and attention to social drivers of health can improve quality of life for a medically and socially complex patient.
Use of Computed Tomography and Magnetic Resonance Angiograms Combined with a 3D Surgical Guide in an Elderly Cat with an Occipital Lobe Meningioma

Simple Summary Meningioma treatments, including complete surgical resection, debulking, radiation therapy, and palliative care in dogs and cats have recently been improved. Although complete resection of meningiomas is known to be the most effective treatment, there are still challenges in performing safe surgeries due to the presence of numerous vessels surrounding the tumor and brain parenchyma. Many efforts have been made in the field of human medicine to achieve safety, such as preoperative planning using 3D simulation and contrast angiography. Surgical navigation systems have been studied for application, but recently, three-dimensional techniques have helped surgeons perioperatively. This study enhanced the vessels around the meningiomas in the skull and attempted to identify them using 3D computed tomography and magnetic resonance imaging angiography rather than conventional angiography. An 11-year-old castrated male cat was referred to our hospital with a meningioma located in the occipital lobe. The cat showed progressive tetraparesis. Throughout the long-term follow-up, following the complete removal of the meningioma, the cat showed favorable clinical outcomes and no neurological abnormalities. Abstract We present a case of occipital lobe meningioma resection in an elderly cat. The surgery was performed with the goal of avoiding major bleeding. An 11-year-old castrated indoor-only male Persian Chinchilla (5.5 kg) was presented with a month-long history of progressive tetraparesis for a left occipital lobe meningioma. Magnetic resonance imaging revealed a T2-weighted heterogeneously hyperintensity and a T1-weighted well-contrast enhancing extradural mass in the left occipital lobe of the brain. Cerebral angiographic data were obtained using magnetic resonance (MRA) and computed tomography angiography (CTA). Advanced angiograms and virtual reconstruction of images revealed that the tumor was surrounded by the caudal parasagittal meningeal vein. A left caudal rostrotentorial craniotomy and en bloc resection of the tumor were performed, and histopathology revealed a meningioma. Complete neurological recovery was achieved within 10 days after surgery. To the best of our knowledge, this is the first case report describing CTA and MRA findings and favorable clinical outcomes after surgical management of a brain meningioma without severe perioperative complications.
Computer analysis of a rotating axial‐turbomachine blade in coupled bending‐bending‐torsion vibrations

Basic equations are derived for a comprehensive computer analysis for an equivalent lumped parameter system which simulates a pre-twisted, rotating or non-rotating. Timoshenko beam in coupled bending-bending-torsion vibrations. These equations enable one to develop straightforwardly digital computer programs for studying vibration problems related to compressor or turbine blades in turbomachinery as well as in other structural dynamics applications. The validity of the lumped parameter approach is established through a free vibration study. Good agreement between the present computer results and those obtained theoretically or experimentally by other investigators is demonstrated. In particular, it is found that the natural frequencies obtained in the free vibration study for all beams examined converge from below the exact values at a convergence rate of N−4, where N is the total number of the lumped parameters used in the computer simulation. The rapid rate of convergence shows that the mathematical model used in deriving the basic equations can adequately represent the type of beams under consideration. The known convergence rate also provides an estimate on the accuracy of the computer results, and a means to improve these results by extrapolation.
Quantum cascade laser with plasmon‐enhanced waveguide operating at 8.4 μm wavelength

A unipolar cascade laser operating at 8.4 μm wavelength is reported. The structure, grown by molecular beam epitaxy in the AlInAs/GaInAs material system, contains a 25‐stage coupled‐quantum‐well active region. The waveguide design is optimized to enhance optical confinement and reduce losses associated with the interface plasmon mode, by taking advantage of the dispersion of the refractive index of the contact layer near the plasma frequency. The peak optical power is 30 mW and the threshold current density 2.8 kA/cm2, at a heat‐sink temperature of 100 K and the highest operating temperature is 130 K. The slope efficiency at 100 K is ∼0.1 W/A, corresponding to a differential quantum efficiency of 5.4% per stage. This work, combined with previous results on shorter wavelength quantum cascade lasers, demonstrates that the wavelength of these new light sources can be tailored over a wide range by changing the active layers’ thicknesses using the same materials.
A surface-based approach to measuring spatial segregation

Quantitative indices of residential segregation have been with us for half a century, but suffer significant limitations. While useful for comparison among regions, summary indices fail to reveal spatial aspects of segregation. Such measures generally consider only the population mix within zones, not between them. Zone boundaries are treated as impenetrable barriers to interaction between population subgroups, so that measurement of segregation is constrained by the zoning system, which bears no necessary relation to interaction among population subgroups. A segregation measurement approach less constrained by the chosen zoning system, which enables visualization of segregation levels at the local scale and accounts for the spatial dimension of segregation, is required. We propose a kernel density estimation approach to model spatial aspects of segregation. This provides an explicitly geographical framework for modeling and visualizing local spatial segregation. The density estimation approach lends itself to development of an index of spatial segregation with the advantage of functional compatibility with the most widely used index of segregation (the dissimilarity index D). We provide a short review of the literature on measuring segregation, briefly describe the kernel density estimation method, and illustrate how the method can be used for measuring segregation. Examples using a simulated landscape and two empirical cases in Washington, DC and Philadelphia, PA are presented.
An enhanced polygonal finite‐volume method for unstructured hybrid meshes

Irregular hybrid meshes may excessively distort the node‐dual finite‐volume discretization. A new scheme is formulated that uses a different type of polygonal control volume. Superior stability of the polygonal scheme over the conventional node‐dual scheme is demonstrated on representative irregular hybrid meshes for incompressible viscous flow past a circular cylinder.

Racism against immigrants in Brazil: a critical analysis of employers' discourse

Objective: This article investigates the discursive representations related to racism of Brazilian employers and human resource managers on hired immigrant workers. Theoretical framework: The socio-cognitive theory proposed by Van Dijk is presented together with studies on discursive representations of immigrants. Methodology: The qualitative research used semi-structured interviews with 12 employers in the cities of São Paulo, Belo Horizonte and Porto Alegre. Data analysis was based on critical discourse analysis (CDA), on Van Dijk's socio cognitive approach. Results: The research showed that the employers' discourse is based on the assumptions that the immigrant workers: i) are more efficient than Brazilians; ii) subject themselves to any kind of work; iii) are destined for unqualified and hard work; iv) threaten Brazilians (different cultural identities; different community values; may be criminals; are disease spreaders); and v) are an economic burden. The Brazilian employer´s discourse maintains and perpetuates all the characteristics of the racist ideology and makes it difficult for immigrants to enter the Brazilian labour market, forging domination practices that favour social inequality. Originality: This study contributes to broaden the CDA scope of analysis when investigating employers and immigrants. It also dialogues and contributes to the literature in Brazil on CDA by specifically adopting Van Dijk's socio cognitive approach instead of the more adopted Fairclough perspective.
Exclusive breastfeeding after breast cancer. Case study

Abstract Objective. To develop a care plan focused on assisting a puerperal woman who decides to feed their child through breastfeeding on the contralateral breast. Methods. A case study conducted with a 36-year-old primiparous woman who underwent tumorectomy and left axillary emptying, chemotherapy and radiotherapy 8 years ago. The data were collected in the Nursing process, with initial assessment using the Marjory Gordon functional health patterns. The care plan used the NANDA-I, NIC and NOC taxonomies. Results. Three diagnoses were identified: [00208] Readiness for Enhanced Childbearing Process, [00106] Readiness for Enhanced Breastfeeding and [00167] Readiness for Enhanced Self-Concept. The indicators were evaluated in the initial and later phase, with gains in the first two diagnoses. The third diagnosis proved to be partially sufficient, as it did not allow assessing the developmental and non-pathological self-image in the puerperium. In the puerperal phase, maternal roles are challenging and demanding. Nursing care contributed to the adaptation to breastfeeding in the contralateral breast and to the guarantee of adequate nutrition for the newborn. The childbearing process was strengthened. Breastfeeding is carried out with maternal satisfaction, good latch and normal weight evolution in the newborn. Conclusion. The case study strengthened knowledge by addressing a little investigated theme. The NANDA-I taxonomy may need further study in the Self-perception domain, more specifically in the self-image reported during the pregnancy-puerperal phase.
Cryptic mtDNA Diversity of Diopatra cuprea (Onuphidae, Annelida) in the Northwestern Atlantic Ocean

Simple Summary Molecular tools continue to reveal cryptic biodiversity within common and ecologically important species. The decorator worm Diopatra cuprea is an ecosystem engineer of intertidal beds of high-salinity estuaries of the Atlantic and Gulf of Mexico shorelines. Here, we sequenced mitochondrial cytochrome oxidase I (COI) in D. cuprea populations and discover evidence for several deep mitochondrial lineages, suggesting the presence of cryptic diversity. Abstract Marine annelid taxonomy is experiencing a period of rapid revision, with many previously “cosmopolitan” species being split into species with more limited geographic ranges. This is exemplified by the Diopatra genus, which has recently witnessed dozens of new species descriptions rooted in genetic analyses. In the northwestern Atlantic, the name D. cuprea (Bosc 1802) has been applied to populations from Cape Cod through the Gulf of Mexico, Central America, and Brazil. Here, we sequenced mitochondrial cytochrome oxidase I (COI) in D. cuprea populations from the Gulf of Mexico to Massachusetts. We find evidence for several deep mitochondrial lineages, suggesting that cryptic diversity is present in the D. cuprea complex from this coastline.
Nd-Doped ZnO Nanostructures with Enhanced Photocatalytic Performance for Environmental Protection

Neodymium (Nd)-doped ZnO nanostructures with different amounts of Nd were obtained by the electrospinning–calcination method. X-ray diffraction measurements indicated that the prepared nanostructures have a wurtzite structure without undesirable impurities. Nd doping changes the mean crystallite size as well the lattice strain, as proved by Williamson–Hall plots. The ZnO-based nanostructures were tested as photocatalysts for methylene blue (MB) dye and ciprofloxacin (CIP) drug pollutant degradations under visible light irradiation. Corroborating the obtained results, it was found that the reaction rate constant increased almost linearly with the mean crystallite size (from 2.235 × 10−2 to 3.482 × 10−2 min−1) with a variation in the mean crystallite size from 24.2 to 42.1 nm. Furthermore, the best catalyst sample (0.1% Nd-doped ZnO) was used to optimize the photodegradation process of ciprofloxacin, taking into account the pollutant concentration as well as the catalyst dose. The removal efficiency after 120 min was about 100%, with the rate constant of k = 5.291·10−2 min−1 (CIP) and k = 4.780·10−2 min−1 (MB) for the established optimal conditions. Considering the value of the rate constant, the half-life of the reaction (τ1/2 = ln2/k) was evaluated to be about τ1/2 =13 min for CIP and 14.5 min corresponding to MB. Several catalytic cycles were successfully performed without any loss of photocatalytic activity using these nanostructures, demonstrating that the obtained nanostructures have good stability in the leaching processes.
Finite-time filtering for non-linear stochastic systems with partially known transition jump rates

This study is concerned with the problem of robust finite-time filtering for a class of non-linear Markov jump systems (MJSs) with partially known information on the transition jump rates. The non-linearities in the system are parameterised by multilayer neural networks. Our attention is focused on the design of a mode-dependent full-order H∞ filter to ensure the finite-time boundedness of the filtering error system and a prescribed H∞ attenuation level for all admissible uncertainties and approximation errors of the networks. Sufficient conditions of filtering design are developed in terms of solvability of a set of linear matrix inequalities. A tunnel diode circuit is used to show the effectiveness and potentials of the proposed techniques.
Advances in Seasonal Predictions of Arctic Sea Ice With NOAA UFS

The Unified Forecast System (UFS) is the next generation modeling infrastructure under development for NOAA's operational numerical weather/climate predictions. This study is the first attempt with UFS for seasonal predictions application. In particular, 9‐month hindcasts are performed starting from every month during 2007–2020. The UFS performance in predicting Arctic sea ice was compared to hindcasts by (a) the current operational Climate Forecast System version 2 (CFSv2) and (b) an experimental sea ice prediction system (CFSm5) at NOAA. Evaluations indicate that UFS demonstrates consistently improved skills than both CFSv2 and CFSm5 in seasonal sea ice predictions, together with more realistic climatological sea ice distributions. Diagnostics suggest that the better climatological sea ice distributions in UFS is related to its atmospheric states simulated with FV3, the atmospheric component of UFS, and reinforced by associated ocean circulations. In addition, applications of the multi‐model ensemble strategy do not present skill improvements over the UFS forecasts alone.
Theoretical Analysis and Experimental Verification of the Influence of Polarization on Counter-Propagating Optical Tweezers

Counter-propagating optical tweezers are experimental platforms for the frontier exploration of science and precision measurement. The polarization of the trapping beams significantly affects the trapping status. Using the T-matrix method, we numerically analyzed the optical force distribution and the resonant frequency of counter-propagating optical tweezers in different polarizations. We also verified the theoretical result by comparing it with the experimentally observed resonant frequency. Our analysis shows that polarization has little influence on the radial axis motion, while the axial axis force distribution and the resonant frequency are sensitive to polarization change. Our work can be used in designing harmonic oscillators which can change their stiffness conveniently, and monitoring polarization in counter-propagating optical tweezers.
Highly-nonlinear quantum-engineered polaritonic metasurfaces

Intersubband transitions in n-doped semiconductor heterostructures allow one to quantum-engineer one of the largest known nonlinear response in condensed matter systems but only for the electric field polarized normal to semiconductor layer. By coupling of a quantum-engineered multi-quantum-well semiconductor layer with electromagnetically-engineered plasmonic elements we may produce ultrathin metasurfaces with giant nonlinear response. Here we experimentally demonstrate metasurfaces designed for second harmonic generation at λ≈9.9 μm with a record-high nonlinear response for condensed-matter systems in infrared/visible spectral range, up to 1.17×106 pm/V. The practical impact of the nonlinear metasurfaces proposed here may be extended to a variety of fields, including THz generation and detection, phase conjugation, and other nonlinear optical processes.
Directed Functional Brain Connectivity is Altered in Sub-threshold Amyloid-β Accumulation in Cognitively Normal Individuals

Several studies have shown that amyloid-β (Aβ) deposition below the clinically relevant cut-off levels is associated with subtle changes in cognitive function and increases the risk of developing future Alzheimer’s disease (AD). Although functional MRI is sensitive to early alterations occurring during AD, sub-threshold changes in Aβ levels have not been linked to functional connectivity measures. This study aimed to apply directed functional connectivity to identify early changes in network function in cognitively unimpaired participants who, at baseline, exhibit Aβ accumulation below the clinically relevant threshold. To this end, we analyzed baseline functional MRI data from 113 cognitively unimpaired participants of the Alzheimer’s Disease Neuroimaging Initiative cohort who underwent at least one 18F-florbetapir-PET after the baseline scan. Using the longitudinal PET data, we classified these participants as Aβ negative (Aβ−) non-accumulators (n = 46) and Aβ− accumulators (n = 31). We also included 36 individuals who were amyloid-positive (Aβ+) at baseline and continued to accumulate Aβ (Aβ+ accumulators). For each participant, we calculated whole-brain directed functional connectivity networks using our own anti-symmetric correlation method and evaluated their global and nodal properties using measures of network segregation (clustering coefficient) and integration (global efficiency). When compared to Aβ− non-accumulators, the Aβ− accumulators showed lower global clustering coefficient. Moreover, the Aβ+ accumulator group exhibited reduced global efficiency and clustering coefficient, which at the nodal level mainly affected the superior frontal gyrus, anterior cingulate cortex, and caudate nucleus. In Aβ− accumulators, global measures were associated with lower baseline regional PET uptake values, as well as higher scores on the Modified Preclinical Alzheimer Cognitive Composite. Our findings indicate that directed connectivity network properties are sensitive to subtle changes occurring in individuals who have not yet reached the threshold for Aβ positivity, which makes them a potentially viable marker to detect negative downstream effects of very early Aβ pathology.
Low frequency response of a resistive plasma to axially independent or axisymmetric perturbations

A formalism is described which permits calculation of the low frequency response of a resistive plasma with non-circular cross-section in magnetohydrodynamic equilibrium to an externally imposed current field in the direction of the ignorable co-ordinate. This formalism is limited to slow variations on the resistive penetration or ‘skin’ time-scale and eliminates rapid motions at the hydrodynamic rate. It is useful for calculating the effectiveness of low frequency Ohmic heating and for the study of feedback stabilization. It also determines stability criteria and gives estimates of growth rates. The presence of a hyperbolic axis in the Doublet configuration makes the incorporation of a finite resistivity in the treatment important.

The design was evidenced from the dimensions: Intrapersonal, psychological and behavioral related to masculinities, interpersonal, organizational and structural, ecological, ethnoracial, cross-cultural and transpersonal. Conclusion. The concept of men's health care revealed the male specificities regarding the recognition of the place of health care and the daily exercise in the lived experience.
Enhancing Performance and Perceived Justice in Hospitality Organizations: An Integrated Model of Gender Diversity Within Top Management Teams

Prior research has produced conflicting findings regarding the positive outcomes of having gender diversity within top management teams. These studies have not considered the industry-specific context, the incorporation of binary, agender, and transexual traits, and potential non-financial outcomes, which play a role in organizational performance. Therefore, this paper aims to further this research by offering a research framework that is hospitality specific, highlights the benefits of gender diversity, and delineates the impact of gender diversity on firm performance and organizational justice based upon previous research and theories. The authors introduce potential processes and facilitators influencing the relationship between gender diversity, organizational performance, and organizational justice. These mechanisms have the potential to shape strategic changes, influence employee behaviors, increase service levels, and ultimately provide a competitive advantage.
