Surgical outcomes of premeatal and retromeatal cerebellopontine angle meningioma in Vietnam: a single-center prospective cross-sectional study

Background: Cerebellopontine angle (CPA) meningiomas are the second most common tumor of the CPA. Depending on the site of dural attachment, the relationship between the tumor and critical neurovascular structures of the CPA is variable. This study aims to evaluate the influence of CPA meningioma location in relation to the internal auditory canal (IAC) on clinical symptoms, radiological presentations, and surgical treatments and outcomes which has been rarely reported in Vietnam. Patients and methods: A prospective study on 33 patients treated with microsurgery from August 2020 to May 2022 at the Neurosurgery Center, Viet Duc University Hospital. Results: The mean age of 27 females (85%) and 6 (15%) males was 54±12 years. Based on their location to the IAC, there were 16 premeatal cases (49%) (anterior to the IAC) and 17 retromeatal cases (15%) (posterior to the IAC). The time of diagnosis of the retromeatal group was later (16.5 vs. 9.7 months), the average tumor size of the 2 groups was not different, but when there was brainstem compression, the average tumor size of retromeatal group was larger (49 vs. 44 mm). The clinical presentations of the retromeatal group were related to the cerebellar symptoms, while trigeminal neuropathy symptoms all came from the premeatal group. Gross total resection of the premeatal group was 31% and of the retrometal group was 71%. The results of preserving the facial nerve function of the premeatal group were lower (44 vs. 82%). Postoperative Karnofsky score of the retromeatal group improved, while the premeatal group did not change. Conclusions: Classification of CPA meningiomas according to their location to the IAC plays an important role in diagnosis and treatment, affecting clinical symptoms, surgical strategy as well as surgical outcomes.
On molecular statics simulations of ferroelectric functional materials

The simulation of ferroelectric materials on the atomistic length scale is getting more and more important due to recent advancements in related manufacturing technologies. Therefore, we present an extended molecular statics algorithm in order to not only compute equilibrium configurations efficiently but also to consider the deformation of a discrete particle system due to macroscopic stress. Furthermore, we discuss the impact of mechanical stress and strain on the spontaneous polarization and the magnitude of the coercive field of a ferroelectric barium titanate system.

Composition and connectivity variability of the A15 phase in PIT Nb3Sn wires

Powder-in-tube (PIT) Nb3Sn wires are competing with Restacked-Rod-Process (RRP®) for the realization of the high luminosity upgrade of the Large Hadron Collider (LHC) at CERN. These two conductors have different properties and microstructures that are in both cases averages of an inhomogeneous A15 microstructure. PIT has in general a smaller fraction of A15 in the non-Cu cross-section than RRP® and a lower non-Cu Jc (12 T, 4.2 K) (2500–2700 A mm−2 versus 2900–3000 A mm−2) but it can be made in smaller filament diameters, which is an important property for LHC magnets. Another characteristic of PIT A15 is that ∼25% is made up of ∼1–2 μm sized grains (typically ∼10 times the small grain (SG) diameter) and their contribution to transport is uncertain. Here we studied a 192 filament Ta-doped, 1 mm diameter PIT wire and combined multiple characterization techniques in order to distinguish the different wire components, to determine their individual properties and to identify which components are current-carriers. We found multiple evidence that the large A15 grains, which are also the highest-Tc grains, do not contribute to transport at high field and that the only current-carrying A15 is the SG with Tc <17.7 K. However, because of the high density of grain boundaries in the SG A15 layer, PIT has an exceptionally high SG-layer Jc and high specific grain boundary pinning force, QGB. These findings clearly show that it is essential to increase the ratio of small to large and disconnected grains in order to improve PIT performance.
Date of birth and the incidence of acute ischemic stroke in Hungary

Introduction. The effect of the date of birth on the incidence of cardiovascular disease was confirmed in earlier studies. We aimed to determine whether the season of birth may be associated with a higher incidence of stroke in later life by analyzing thrombolysis numbers according over a ten-year period in Hungary. Patients and methods. We analyzed daily thrombolysis numbers between 2007 and 2016 according to the patients’ date of birth based on seasons. The correlation between cumulative thrombolysis numbers between 2007 and 2016 per month and birth numbers per month based on data of the 1949 census were also examined. Results. Our results indicate that being born in the spring and summer in the northern hemisphere may be associated with a higher frequency of ischemic stroke necessitating thrombolytic treatment. This equates to a higher risk when conception and early pregnancy occur in the summer and autumn months. Conclusions. This, however, cannot be defined as a causal relationship if we consider the number of live births in 1949, as both measures change similarly during the year, as indicated by the strong positive correlation between thrombolysis frequency according to date of birth between 2007 and 2016 and the number of births in the 1949 census by month.
A Data-Model Interactive Remaining Useful Life Prediction Approach of Lithium-Ion Batteries Based on PF-BiGRU-TSAM

Accurate remaining useful life (RUL) prediction of lithium-ion batteries is critical for energy supply systems. In conventional data-driven RUL prediction approaches, the battery's degradation mechanism is difficult into incorporate in the RUL prediction. Furthermore, there are notable limitations in reflecting the significance of different time instances, and the uncertainty in the degradation process. Consequently, a novel data-model interactive RUL prediction approach based on particle filter-temporal attention mechanism-bidirectional gated recurrent unit (PF-BiGRU-TSAM) is proposed. Specifically, BiGRU-TSAM is trained offline through historical data, which assigns corresponding significance to battery capacities at different time instances. Moreover, regarding the interactive data-model for the online prediction phase based on PF-BiGRU-TSAM, the advantages of data-driven and model-based approaches are integrated, which accomplishes the purpose of modifying each other. The proposed PF-BiGRU-TSAM approach is validated with a real-world battery dataset. Experimental results demonstrate the proposed approach is better than some published approaches. Taking the 50th operational cycle of the four batteries B0005, B0006, B0007, and B0018 in the dataset as an instance, the absolute errors of the proposed PF-BiGRU-TSAM are 0, 1, 3, 3, respectively, which represents the proposed approach has an excellent performance.
The Effect of Daily Meditative Practices Based on Mindfulness and Self-Compassion on Emotional Distress under Stressful Conditions: A Randomized Controlled Trial

Intervention programs based on self-compassion have demonstrated their efficacy both in reducing psychological distress and increasing well-being. The goal of this study was to test the efficacy of an online intervention to increase mindfulness and self-compassion levels in a non-clinical sample in a highly stressful context: the ten weeks of lockdown imposed in the early stages of the COVID-19 pandemic. The intervention sessions consisted of thirty-minute guided meditations followed by thirty minutes of inquiry. Sixty-one participants completed two thirds of the sessions or more, and 65 individuals participated in a waiting-list (WL) control group. Self-compassion, anxiety, depression and stress levels were assessed. The analysis of pre-post results suggests that the interventions increased self-compassion levels and decreased anxiety, depression and stress levels, whereas the WL group did not show any significant changes. The emotional changes in the intervention group were associated with the increase in self-compassion. However, at follow-up, the scores of emotional distress variables returned to the initial pre-intervention scores. These data can be interpreted in line with previous results that have shown the efficacy of self-compassion-based intervention programs. Given that this efficacy was not maintained at follow-up, data are discussed according to the pervasive role of a highly stressful context and—as described in other studies—the need for regular practice to maintain the benefits obtained.
Toward multidimensional activity space-based segregation research

Measuring and explaining sociospatial segregation is essential in urban and social geography. Recent advances in activity space-based segregation provide new opportunities to study sociospatial segregation. This paper provides a comprehensive review of the emerging activity space-based segregation research in terms of measurements, dimensions, and influential factors. We highlight the trend toward integrating spatial, temporal, and social dimensions in activity space-based segregation measurement. Then, a multidimensional framework is constructed to cover the spatial form, opportunity exposure, spatiotemporal interaction, and social relationship of activity space-based segregation research. This paper ends with challenges and future directions for activity space-based segregation research, highlighting the importance of the temporal dimension, social interaction, influential mechanisms, and social effects.
Blocking algorithms for structured mesh generation

A theoretical and algorithmic framework for 3-D blocking has been developed based on novel generalizations of topological graph theory. Elements of this development include: the representation of surface blockings by graphs with rotation systems, the use of hypergraphs in 3-D blocking, interpretation of 3-D computational space as a weighted hypergraph with rotation system and the development of algorithms for constructing hypergraphs in the presence of geomeaic obstructions. Application of these algorithms to a submarine geometry are presented.

Role of gut microbiota in the modulation of the health effects of advanced glycation end-products (Review)

The aim of the present review was to summarize the potential interactive effects between the gut microbiota and advanced glycation end-product (AGE) accumulation and toxicity in the host, and to reveal potential the mediatory effects of the gut microbiota on AGE-related health effects. The existing data demonstrate that dietary AGEs can have a significant impact on the richness and diversity of the gut microbiota, although the particular effect is dependent on the type of species, as well as the exposure dose. In addition, the gut microbiota may metabolize dietary AGEs. It has been also demonstrated that the characteristics of the gut microbiota, including its richness and relative abundance of certain taxa, is tightly associated with AGE accumulation in the host organism. In turn, a bilateral interplay between AGE toxicity and the modulation of the gut microbiota may contribute to pathogenesis of ageing and diabetes-associated diseases. Bacterial endotoxin lipopolysaccharide appears as the molecule that mediates the interactions between the gut microbiota and AGE toxicity, specifically via the modulation of the receptor for AGE signaling. Therefore, it is proposed that the modulation of the gut microbiota using probiotics or other dietary interventions may have a significant impact on AGE-induced glycative stress and systemic inflammation.
Effect of U3O8 Specific Surface Area on In Vitro Dissolution, Biokinetics, and Dose Coefficients

The purpose of this study was to investigate the effect of the specific surface area (SSA) of U 3 O 8 , sampled from different processes, on its in vitro dissolution, its biokinetics in rats, and dose coefficient. A knowledge of the manufacturing process as well as the physico-chemical properties of uranium oxides are necessary to understand why the solubility and consequently the dose may vary for the same chemical form of a compound. Eight preparations of U 3 O 8 with different SSA, have been characterised. In vitro chemical dissolution tests, in culture medium, have shown an increase of solubility with SSA. In vivo experiments involving intratracheal deposition of a suspension of the oxides showed that the amount of uranium absorbed into blood increased 3-fold when the SSA increased 5-fold. Calculations of the dose coefficients from in vitro dissolution parameters, have shown a decrease from 4.30 to 1.75 μSv. Bq -1 when the SSA increased from 0.7 to 15.5 m 2 . g -1 . Dose coefficients calculated from in vivo absorption parameters varied from 5.5 to 4.2 μSv. Bq -1 , when the SSA increased from 0.7 to 3.2 m 2 . g -1 .
Walkable Neighborhoods

Abstract Problem, research strategy, and findings We examined whether living in a walkable neighborhood influenced the happiness of younger and older city residents. The data for this study came from a comprehensive household population survey of 1,064 adults living in 16 neighborhoods in Dublin City (Ireland) and its suburbs. We used multigroup structural equation modeling to analyze the direct and indirect effects of walkability on happiness, mediated by health, trust, and satisfaction with neighborhood appearance. We found living in a walkable neighborhood was directly linked to the happiness of people aged 36 to 45 (p = .001) and, to a lesser extent, those aged 18 to 35 (p = .07). For older adults, we found that walkable places mattered for happiness indirectly. Such built environments enhanced the likelihood that residents felt more healthy and more trusting of others, and this in turn affected the happiness of older people living in walkable neighborhoods. Takeaway for practice We found that the way neighborhoods are planned and maintained mattered for happiness, health, and trust. Our findings suggest that mixed-use neighborhood designs that enable residents to shop and socialize within walking distance to their homes have direct and indirect effects on happiness. We call for an ongoing dialogue and evaluation of the way our urban and suburban neighborhoods are planned, designed, and developed, so that people can live in walkable places that better enable health and wellbeing.
SPASER as a complex system: femtosecond dynamics traced by ab-initio simulations

Integrating coherent light sources at the nanoscale with spasers is one of the most promising applications of plasmonics. A spaser is a nano-plasmonic counterpart of a laser, with photons replaced by surface plasmon polaritons and the resonant cavity replaced by a nanoparticle supporting localized plasmonic modes. Despite the large body of experimental and theoretical studies, the understanding of the fundamental properties of the spaser emission is still challenging. In this work, we investigated the ultrafast dynamics of the emission from a core-shell spaser by developing a rigorous first-principle numerical model. Our results show that the spaser is a highly nonlinear system with many interacting degrees of freedom, whose emission sustain a rich manifold of different spatial phases. In the regime of strong interaction we observed that the spaser emission manifests an irreversible ergodic evolution, where energy is equally shared among all the available degrees of freedom. Under this condition, the spaser generates ultrafast vortex lasing modes that are spinning on the femtosecond scale, acquiring the character of a nanoparticle with an effective spin. Interestingly, the spin orientation is defined by spontaneous symmetry breaking induced by quantum noise, which is a fundamental component of our ab-initio model. This opens up interesting possibilities of achieving unidirectional emission from a perfectly spherical nanoparticle, stimulating a broad range of applications for nano-plasmonic lasers as unidirectional couplers, random information sources and novel form of photonics neural-networks.
Semiconductor investigation by terahertz radiation pulses

Several applications of terahertz radiation pulses for characterizing semiconductor bulk materials and structures are described. Terahertz pulses emitted at the surfaces illuminated by femtosecond laser of a tunable wavelength are demonstrated to provide information on the electron energy spectrum in the conduction band as well as on the subsurface band bending. On the other hand, by sampling the conductivity of various structures with short electrical field transient photoexcited electron dynamics can be directly studied at its initial, subpicosecond time scale. Narrow gap semiconductors InSb and InAs as well as novel materials such as GaAsBi or self-assembled InAs quantum dots were characterized by using terahertz radiation pulses.
SERVQUAL METHOD ANALYSIS FOR GENERAL PATIENT HEALTH SERVICE SATISFACTION LEVEL

Puskesmas Pulo Bandring is a functional implementing unit that functions as a center for health development. as a center for health services for the community, Puskesmas are required to always maintain patient trust, by improving the quality of their services. However, in reality in the field there is no system that can measure the level of satisfaction of health services at the Puskesmas Pulo Bandring. To overcome this problem, the researcher uses the Servqual Method, Service Quality is a method used to measure the service quality of the attributes of each dimension, so that the gap value will be obtained which is the difference between consumer perceptions of the services that have been received and expectations of what will be received. received. The data that was processed in this study was obtained by giving a chair containing 22 questions to 30 patients seeking treatment at the Puskesmas Pulo Bandring. It was found that the satisfaction of patients seeking treatment at Puskesmas Pulo Bandring Public seen from the 5 dimensions of the servqual had a reality value of 4.00 and an expected value of 4.62 so that there was a gap of -0.62. This gap occurs due to the non-fulfillment of patient expectations with the quality of services provided by the Puskesmas Pulo Bandring.

MDC-Net: a multi-directional constrained and prior assisted neural network for wood and leaf separation from terrestrial laser scanning

ABSTRACT Wood-leaf separation from terrestrial laser scanning (TLS) is a crucial prerequisite for quantifying many biophysical properties and understanding ecological functions. In this study, we propose a novel multi-directional collaborative convolutional neural network (MDC-Net) that takes the original 3D coordinates and useful features from prior knowledge (prior features) as input, and outputs the semantic labels of TLS point clouds. The MDC-Net contains two key units: (1) a multi-directional neighborhood construction (MDNC) unit to obtain more representative neighbors and enable directionally aware feature encoding in the subsequent local feature extraction, to mitigate occlusion effects; (2) a collaborative feature encoding (CFE) unit is introduced to incorporate useful features from prior knowledge into the network through a collaborative cross coding to enhance the discrimination for thin structures (e.g. small branches and leaf). The MDC-Net is evaluated on five plots from forests in Guangxi, China, with different branch architectures and leaf distributions. Experimental results showed that the MDC-Net achieved an OA of 0.973 and a mIoU of 0.821 and outperformed other related methods. We believe the MDC-Net would facilitate the usage of TLS in ecology studies for quantifying tree size and morphology and thus promote the development of relevant ecological applications.
Aircraft measurements of mountain waves and their associated momentum flux over the British Isles

The Hercules and Canberra aircraft of the Meteorological Research Flight have made a number of flights to investigate mountain waves over different mountainous areas of the British Isles. Results from five flight days are presented in this study. For each flight day the observed values of the dominant wavelength and the wave amplitude as a function of height were compared with the values predicted by two-dimensional linear lee wave theory. Good agreement was obtained in four of the five cases. Measurements of the vertical flux of horizontal momentum show that the largest values were obtained when the wavelength was 20·9 km and the waves were only weakly trapped. On this occasion, the flux was observed to be constant with height in the range over which measurements were made, supporting a theoretical result of Eliassen and Palm. The value –0·35Nm−2 is comparable with some aircraft measurements made over the Rocky Mountains.
