Association of Gut Microbial Dysbiosis and Hypertension: A Systematic Review

Hypertension (HTN) is one of the most prevalent and dangerous cardiovascular diseases worldwide. Recently, its direct or indirect association with gut dysbiosis has been an interest of study for many. It also includes the metabolomic and functional gene changes in hypertensives compared with healthy individuals. This systematic review aims to study quantitative and qualitative interactions between the two and re-defining the heart-gut axis. We have strictly followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), 2020, guidelines. We conducted an in-depth search of databases such as PubMed, PubMed Central (PMC), Medline, and ScienceDirect to find relevant studies for our topic of interest. After the final quality check, we included eight articles in the systematic review. A significant difference in richness and diversity in gut microbiota was observed in hypertensive patients compared with healthy controls. There was an increased abundance of many bacteria such as Catabacter, Robinsoleilla, Serratia, Enterobacteriaceae, Ruminococcus torques, Parasutterella, Escherichia, Shigella, and Klebsiella, while a decreased abundance of Sporobacter, Roseburia hominis, Romboutsia spp. , and Roseburia. Alteration of the composition also varied based on diet, age, ethnicity, and severity of HTN. Short-chain fatty acids (SCFAs)-producing bacteria are found to be on the lower side in hypertensives owing to the protective property of SCFAs against inflammation, especially butyric acid. From the perspective of metabolomic changes, harmful metabolites for cardiovascular health such as intestinal fatty acid binding protein (I-FABP), lipopolysaccharides (LPSs), zonulin, sphingomyelins, acylcarnitines, and trimethylamine N-oxide (TMAO) were found to be increased in hypertensives. Changes in these biomarkers further establish the relation between gut epithelial health and high blood pressure (BP). Participants affected by diseases have an overall lower rate of acquiring new genes, which results in a low richness of genes in them compared with healthy individuals. There is increased expression of the choline utilization (cutC) gene and reduced expression of genes associated with biosynthesis and transport of amino acids in high-BP participants. The unique changes in the composition of the microbiota, functional changes in genes, and metabolome collectively help for a better understanding of the pathogenesis of HTN and also suggest the gut as a promising new therapeutic target for HTN. To establish a further causal relationship between the two, more research is required.
EXPERIMENTAL STUDY OF IMPACT OF IN-SERVICE DETERIORATION ON THERMAL PERFORMANCE OF HIGH-PRESSURE NOZZLE GUIDE VANES

In this paper we analyze the impact of in service deterioration on the overall thermal performance (metal effectiveness) of heavily-cooled high pressure nozzle guide vanes, of a design typical of large civil jet engines. We study 15 deteriorated parts (increased surface roughness; thermal barrier coating spallation and sintering; damaged film cooling holes; and trailing edge burn-back) from operational engines, and compare their thermal performance to that of equivalent new parts. Overall cooling effectiveness measurements were performed in the Engine Component AeroThermal (ECAT) facility at the University of Oxford, at engine representative conditions of Mach number, Reynolds number, coolant-to-mainstream pressure ratio, and turbulence intensity. We characterize the degradation of overall cooling effectiveness with service time; this is an important result for whole-life modelling. In the analysis we attempt to decouple the contributions from independent deterioration effects, and compare the philosophy of this top-down approach to the bottom-up approach in which effects are studied in isolation then superposed in modelling. A companion paper [1] focuses on the aerodynamic impact of in-service deterioration.
On the Synthesis of Continuous-Time Sturdy MASH Delta-Sigma Modulators

Sturdy multi-stage noise-shaping (SMASH) delta-sigma modulators (DSMs) achieve high-order noise-shaping while significantly alleviating the mismatch issue between analog and digital transfer functions. Based on the SMASH architecture, we propose a methodology of synthesizing its continuous-time (CT) architecture from its discrete-time (DT) counterpart by using loop-filter connections. The proposed methodology circumvents the necessity of a direct extraction of the quantization noise from the early stages, which is problematic for CT architectures with high sampling rate. Moreover, the proposed method allows to intuitively compensate the CT SMASH for the excess loop delay (ELD). Furthermore, an input feedforward path is introduced into the second stage to eliminate the STF peaking induced by the ELD. A 2–2 SMASH topology is analyzed as a case study to demonstrate the synthesis methodology. Besides, we present derivations for determining loop-filter coefficients. Simulation results confirm the efficacy of the synthesis methodology for the SMASH topology.
Telling a story in a deliberation: addressing epistemic injustice and the exclusion of indigenous groups in public decision-making

ABSTRACT Deliberative scholars have suggested that citizens should be able to exchange arguments in public forums. A key element in this exchange is the rational mode of communication, which means speaking through objective argumentation. However, some feminists argue that this mode of communication may create or intensify epistemic injustices. Furthermore, we should not assume that everyone is equally equipped to take part in deliberation. Certain groups, such as Indigenous peoples, for instance, who may not be versed in rational forms of argumentation, may not be listened to or involved sufficiently in the deliberative process. Therefore, it seems we need an alternative mode of communication, such as storytelling, which is a first-person or collective narrative. Given this, how should we pursue this goal? This article aims to answer this question by analysing a local conflict involving an Indigenous tribe and a neighbouring community in Brazil and exploring the underlying testimonial and hermeneutical injustices. I argue that storytelling has an important normative and institutional role in public deliberation and show that its applied version could overcome epistemic injustices and lead to better public policies.
Linking Psychological Ownership to Innovative Behaviour in the Workplace: Empirical Evidence from Complex Management Systems in Pakistan

This research work investigates the association between psychological ownership and innovative behaviour with knowledge hiding and knowledge sharing as mediators. The latter variables are presented as focal antecedents of preventive and promotive psychological ownership. To conduct the study, a theoretical framework was proposed, and data was collected from professionals working in complex management systems in Pakistan. The analysis revealed that knowledge hiding and knowledge sharing can exist simultaneously, and psychological ownership can evoke both positive and negative feelings in employees, which poses a challenge for the management. The results illustrate that psychological ownership has significant associations with knowledge hiding, knowledge sharing, and innovative behaviour. Consequent theoretical contributions and important managerial implications are discussed at the end.
Accurate p-mode measurements of the G0V metal-rich CoRoT target HD 52265

Context. The star HD 52265 is a G0V metal-rich exoplanet-host star observed in the seismology field of the CoRoT space telescope from November 2008 to March 2009. The satellite collected 117 days of high-precision photometric data on this star, showing that it presents solar-like oscillations. HD 52265 was also observed in spectroscopy with the Narval spectrograph at the same epoch. Aims. We characterise HD 52265 using both spectroscopic and seismic data. Methods. The fundamental stellar parameters of HD 52265 were derived with the semi-automatic software VWA, and the projected rotational velocity was estimated by fitting synthetic profiles to isolated lines in the observed spectrum. The parameters of the observed p modes were determined with a maximum-likelihood estimation. We performed a global fit of the oscillation spectrum, over about ten radial orders, for degrees l = 0 to 2. We also derived the properties of the granulation, and analysed a signature of the rotation induced by the photospheric magnetic activity. Results. Precise determinations of fundamental parameters have been obtained: Teff = 6100 ± 60 K, log g = 4.35 ± 0.09, [M/H] = 0.19 ± 0.05, as well as v sini = 3.6 +0.3 −1.0 km s −1 . We have measured a mean rotation period P rot = 12.3 ± 0.15 days, and find a signature of differential rotation. The frequencies of 31 modes are reported in the range 1500–2550 μHz. The large separation exhibits a clear modulation around the mean value Δν = 98.3 ± 0.1 μHz. Mode widths vary with frequency along an S-shape with a clear local maximum around 1800 μHz. We deduce lifetimes ranging between 0.5 and 3 days for these modes. Finally, we find a maximal bolometric amplitude of about 3.96 ± 0.24 ppm for radial modes.
ADM Mass on General Spacetime and Hawking-Page Phase Transition in Magnetic Black Brane

We derive a formula which enable us to evaluate the ADM mass in a more general curved spacetime. We apply the formula to evaluate the thermodynamical quantities of the Melvin magnetic black D-branes. We see that there is the Hawking-Page phase transition and the corresponding dual gauge theory will show the confinement-deconfinement transition under magnetic flux.
Becoming Culturally Proficient Qualitative Researchers by Crossing Geographic and Methodological Borders

This article explores how novice researchers develop a scholarly identity as they cross geographic, cultural, institutional, identity, and methodological borders throughout their studies, experiencing insider, outsider, and in-betweener positions. It hypothesizes that researchers become more culturally proficient through their fieldwork and self-study. The autoethnographic narratives address the social justice issues encountered by two early career researchers who increased their cultural proficiency and self-awareness as they moved across multiple cultural contexts. By shifting back and forth between insider, outsider, and in-betweener, the researchers became more culturally proficient, developed their voices as researchers, and practiced inclusivity by amplifying marginalized voices. Their self-reflective analysis of autoethnographic writing speaks to early career and graduate qualitative researchers who must recognize their positionality and their placement on the cultural proficiency continuum to be effective scholars in cross-cultural research.

A Modular Multilevel Converter Station With Multiple MVac Ports

Medium voltage (MV) ac–dc hybrid distribution network attracts much interest due to its high reliability, high power quality, and high compatibility with distributed generation and dc loads. As the key enablers to interconnect ac and dc grids, the converter stations usually adopt the modular multilevel converter (MMC) topology due to its superior modularity and scalability. Unlike the conventional stations that are implemented with multiple MMCs to accommodate multiple ac feeders, a novel multi-ac-port MMC station (MACP-MMC), which evolves from the MMC topology, is proposed in this article to interconnect different ac feeders and facilitate flexible power exchange in the MV hybrid distribution network. In addition to the benefits inherited from the MMC, the proposed MACP-MMC also features easy multiport extension, bidirectional power flow adjustment, high power density, and low cost. The operation principle, energy balance mechanism, and control strategies are elaborated. Finally, its effectiveness is verified by both simulation results in a 3-MVA case and experimental results obtained from a 3-kVA scaled-down lab prototype.
Implications of GRB 130603B and its macronova for r-process nucleosynthesis

The tentative identification of a Li-Paczynski macronova following the short GRB 130603B indicated that a few hundredths of a solar mass of neutron star matter were ejected and that this ejected mass has radioactively decayed into heavy r-process elements. If correct, this confirms long standing predictions (Eichler, Livio, Piran and Schramm 1989) that on the one hand, sGRBs are produced in compact binary mergers (CBMs) and on the other hand that these events are significant and possibly dominant sources of the heavy (A>130) r-process nuclei. Assuming that this interpretation is correct we obtain a lower limit of 0.02 m_sun on the ejected mass. Using the current estimates of the rate of sGRBs and with a beaming factor of 50, mergers associated with sGRBs can produce all the observed heavy r-process material in the Universe. We confront this conclusion with cosmochemistry and show that even though such events are rare, mixing is sufficient to account for the current homogeneous distribution of r-process material in the Galaxy. However, the appearance of significant amounts of Eu in some very low metallicity stars requires that some mergers took place very early on, namely with a very short time delay after the earliest star formation episodes. Alternatively, an additional early r-processsource may have contributed at that early stage. Finally, we note that evidence for short lived {244}^Pu in the very early solar system suggests that a merger of this kind took place within the vicinity of the solar system shortly (a few hundred million years) before its formation.
A comprehensive study of the open cluster NGC 6866

We present CCD $UBVRI$ photometry of the field of the open cluster NGC 6866. Structural parameters of the cluster are determined utilizing the stellar density profile of the stars in the field. We calculate the probabilities of the stars being a physical member of the cluster using their astrometric data and perform further analyses using only the most probable members. The reddening and metallicity of the cluster were determined by independent methods. The LAMOST spectra and the ultraviolet excess of the F and G type main-sequence stars in the cluster indicate that the metallicity of the cluster is about the solar value. We estimated the reddening $E(B-V)=0.074 \pm 0.050$ mag using the $U-B$ vs $B-V$ two-colour diagram. The distance modula, the distance and the age of NGC 6866 were derived as $\mu = 10.60 \pm 0.10$ mag, $d=1189 \pm 75$ pc and $t = 813 \pm 50$ Myr, respectively, by fitting colour-magnitude diagrams of the cluster with the PARSEC isochrones. The Galactic orbit of NGC 6866 indicates that the cluster is orbiting in a slightly eccentric orbit with $e=0.12$. The mass function slope $x=1.35 \pm 0.08$ was derived by using the most probable members of the cluster.
Trauma-Informed Supervision Experiences: A Preliminary Phenomenological Study

Trauma is pervasive in the clinical world of counseling. The current literature indicates adverse effects for survivors of a traumatic event and the counselors listening to the details of traumatic events, but there is a gap in research on the adverse effects trauma in counseling has on supervisors. This study aims to understand the lived experiences of supervisors who have dealt with traumatic experiences in clinical work through interviews with current supervisors of those who work with trauma. The results indicate trauma-informed supervision consists of trauma taking many forms, supervisors (and counselors) using the self in their work, supervisors knowing their stance, and developing a “third eye” as a new way of seeing.
A Novel RF to Millimeter Waves Frequency Translation Scheme for Ultra-Wideband Beamformers Supporting the Sub-6 GHz Band

This work introduces a new class of ultra-wideband beamforming networks (BFNs) that covers the legacy sub-6 GHz bands for both traditional and fifth-generation (5G) satellite and terrestrial communication systems. To cover the multioctave sub-6 GHz bandwidth, we translate the microwave-photonics concept to the radio frequency (RF)-millimeter waves (mm-waves) regime. Based on our novel approach, the desired RF frequency, a sub-6 GHz signal, is first up-converted to a mm-wave frequency, where it undergoes the desired processing (i.e., the required time delays are introduced), and then it is down-converted back to the initial RF frequency for transmission through the antenna array. An example beamforming system is developed to validate the performance of our proposed approach. Also, a modified true-time-delay (TTD) Blass matrix is designed for this system to perform the analog beamforming. This Blass matrix is prototyped, and its performance is validated using simulations and measurements. Our results show that our proposed BFN supports a 6:1 bandwidth, which is the highest bandwidth ever reported in the literature. Additionally, our proposed approach can be extended to significantly higher bandwidths if high mm-wave frequencies are used in our up-conversion stage.
A Novel Hybrid Physics-Based and Data-Driven Approach for Degradation Trajectory Prediction in Li-Ion Batteries

Lithium-ion batteries have been widely used in electric vehicles. To ensure safety and reliability, accurate prediction of the battery’s future degradation trajectory is critical. However, early prediction capability and adaptive prediction capability under various battery aging conditions remain two main challenges. Either physics-based or data-driven methods have their advantages and limitations. In this study, a novel hybrid method that combines the physics-based and data-driven approaches is proposed to achieve early prediction of the battery capacity degradation trajectory. This framework consists of three steps. First, to improve the generality of the method, a hybrid feature is extracted using an electrochemical model and measured voltage data. Second, the clustering algorithm is adopted to divide battery degradation data into different clusters, and the data augmentation technique is used to enrich the training dataset. Finally, the training dataset in each cluster is used to train the sequence-to-sequence deep neural network, and the future degradation trajectory can be predicted. The proposed method provides accurate predictions using only 20% of training data, and it has strong robustness under noisy input. Validation results under different aging conditions show that the mean absolute percentage errors of capacity degradation trajectory and remaining useable cycle life are below 2.5% and 6.5%, respectively.
Defects and multistability in eutectic solidification patterns

We use three-dimensional phase-field simulations to investigate the dynamics of the two-phase composite patterns formed upon during solidification of eutectic alloys. Besides the spatially periodic lamellar and rod patterns that have been widely studied, we find that there is a large number of additional steady-state patterns which exhibit stable defects. The defect density can be so high that the pattern is completely disordered, and that the distinction between lamellar and rod patterns is blurred. As a consequence, the transition from lamellae to rods is not sharp, but extends over a finite range of compositions and exhibits strong hysteresis. Our findings are in good agreement with experiments.
The value of visual co-analysis models for an inclusive citizen science approach. Inspired by co-creation methods from design thinking

Citizen science entails the collaboration of citizens and scientists. The process of this collaboration can take on many forms: identifying a research question, collecting data, analysing data to support or refute a hypothesis, monitoring environmental or health conditions for management or policy development. Citizen science propagates the inclusion of citizens not only as participants engaged in the design research process but also involved in designing the research process itself. In order to address issues of a citizen science approach, it is important that potentially everyone can contribute. Therefore, methodologies need to be fine-tuned to improve the involvement of non-professional researchers in the research process. Co-creation methods may be an effective methodology for doing so and bring different types of knowledge (e.g., insights, experiences, data, information) to the ‘table of science’ and, ultimately, improve the constructive exchange and evaluation of this knowledge. This article describes the process of a pilot where professional researchers, informal caregivers, and human resource advisors use visual co-analysis to create a research plan. For the framing of this research a theme was proposed which focused on the possibility of technological support for work-related challenges experienced by informal caregivers working in healthcare. Five semi-structured interviews were conducted by researchers with informal caregiver in the first phase of ‘Empathize’ within design thinking (i.e., human centred approach). The goal of the interviews was to understand and relate to the caregiver’s perception of their current informal care situation (e.g., balance, bottlenecks, opportunities, well-being). Quotes selected from theses interviews were the input for a bottom-up methodology for citizen science using the KJ Method (i.e., affinity diagramming) as a form of visual analysis model. The (co-)analysis was done by the team of caregivers, HR advisors and researchers using the online tool Miro. This article aims to describe how the use of visual analysis models as a group consensus technique can facilitate the involvement of non-professional researchers and thereby support the establishment of inclusiveness of a citizen science approach. In other words, to obtain equal collaboration, an inclusive citizen science approach must allow communication about, and analysis of data by all participants, instead of non-professional researchers merely being presented with the finalized results of the analysis phase within research. An inclusive citizen science approach might lead to a period of uncertainty where problem definitions, research questions or predefined categories posed early on are (re-)assessed. However, this bottom-up approach will ultimately lead to a positive impact in finding the root problem for innovative scientific outcomes. Together, the pilot study and descriptive review offer guidance for understanding visual co-analysis models as the starting point for an inclusive citizen science approach.
