Published: April 2023

Abstract
Air intakes are an integral part of contemporary passenger and military aircraft engines. Their impact on aerodynamic performance across the entire flight envelope is critical to aircraft flight safety, efficiency, and maneuverability, especially at high Mach numbers due to shock waves. The high demand for reduction in aircraft weight and size and enhancement of durability, comfort, and thermal and radar signatures compels researchers and engineers to explore new designs and develop efficient air intakes for high-performance aircraft engines. Although a number of studies on air intake have been conducted and reported in the open literature, there is little information available in the public domain on bifurcated twin air intakes using synthetic jet. As a result, the primary goal of this research is to use high-fidelity computational fluid dynamics modelling to investigate the effects of synthetic jets on swirl inflow variable geometry twin air intake aerodynamic performance over a range of Reynolds numbers. Some important parameters (distortion coefficient, non-uniformity index, swirl coefficient, and static and total pressure coefficients) were investigated. Both static and total pressure recovery have been increased at all swirl numbers. A significant decrease in distortion coefficient and swirl coefficient has also been achieved, reaching 67% in both cases. The reduction in the non-uniformity index is achieved by 62% for the controlled flow case. The findings show that the synthetic jets are effective in controlling the flow separation in the twin air-intakes and enhancing aerodynamic performance.
In-Depth, Breadth-First, or both? Characterising the information search process in a PublicTransport SP Experiment

Abstract

Development and innovation in discrete choice modelling has been dominated by Random Utility Maximization approaches due to their ease of application and high economic interpretability. However, this model assumes that decision-makers perform an in-depth information search process implicitly and instantaneously. In particular, it has not been investigated in detail whether the information search process of transport users is in-depth or breadth-first in a public transport choice context, a gap that this research aims to fill. To this end, the information search process of public transport users has been characterized by stated preference surveys with click-tracking. Specifically, three pivoted SP surveys concerning morning peak trips were designed and applied, varying in the number of alternatives and attributes (areas of interest shown: AOI). These values were displayed as an information board, where only one attribute is visible at a time, and clicks were recorded to evaluate the respondents' information search process. Three main conclusions can be drawn from the findings. First, the pattern of searching for information in breadth-first predominates independently of the AOIs displayed. Second, more searches are performed than the amount of information displayed and this value increases at a decreasing rate with increasing AOIs. Third, the most likely transitions during the deliberation process are those that arise from breadth-first searches. In summary, the evidence found suggests that there is a dominance of breadth-first searches, so the RUM model would not be able to describe the deliberation process adequately and that the assumptions of the RRM or DFT models would be more appropriate for these purposes.
Central role of the habenulo-interpeduncular system in the neurodevelopmental basis of susceptibility and resilience to anxiety in mice

Abstract
Having experienced stress during sensitive periods of brain development strongly impacts how individuals cope with later stress. Many become more prone to develop anxiety or depression, but some appear resilient. The as-yet-unknown mechanisms underlying these differences may lie in how genes and environmental stressors interact to shape the circuits controlling emotions. Here, we investigated the role of the habenulo-interpeduncular system (HIPS), a critical node of reward circuits, in early stress-induced anxiety in mice. Based on immediate early gene expression, we found that a subcircuit of this system, characterized by Otx2 expression, is particularly sensitive to chronic restraint stress during the peripubertal period, and that this induces hypersensitivity of the HIPS to later stress and susceptibility to develop anxiety. We also show that conditional knockout of Otx2 restricted to the HIPS in mice counteracts these effects of stress. Together, these results demonstrate that a genetic factor, Otx2, and stress interact around puberty to shape the stress sensitivity of the HIPS, revealing this sensitivity as a key modulator of susceptibility/resilience to develop anxiety.

Published: April 2023

At the commencement of Indonesian independence, the Masyumi Party was the sole prominent Islamic party. It attempted to include Islam as the foundation of the Indonesian state into its constitution. This study aims to investigate the effort of the Masyumi during their active participation and administration of the government throughout the Old Order period in the context of fiqh al-siyāsah. This research is a qualitative legal study employing the approach of fiqh al-siyāsah or Islamic politics. Meanwhile, data collection techniques were carried out through literature studies and in-depth interviews. The results of this study indicate that Masyumi's efforts in the Constituent Assembly, whose task is to draft the Indonesian State Constitution, were carried out very seriously and earnestly, causing the work of the Constituent Assembly members to drag on because there was no point of convergence between the Masyumi Islamic Party and the national parties. As a result of the absence of a meeting point, President Soekarno, with the support of the Indonesian Army, issued a decree on July 5, 1959, dissolving the Constituent Assembly and reverting to the 1945 Constitution. It turned out that the failure of Masyumi's hard work to make Islam the basis of the state was due to internal factors: communist, nationalist, and secularist ideology. In addition, it was also influenced by several external factors: the infiltration of the global superpowers and Islamophobia. Despite the fact that Masyumi was deemed a failure, various contributions in the context of fiqh al-siysah in Indonesia, particularly resistance to communism, contributed color to an Islamic state administration system as well as adherence to the constitution and theistic democracy.

BACKGROUND: In March 2020, due to the COVID-19 pandemic, hospitalizations in New York state were restricted to emergency purposes. Non-COVID related cases involving lower extremity wounds were only admitted for acute infections and limb salvage. Patients with these conditions were placed at higher risk for eventual limb loss. PURPOSE: To understand the impact of COVID-19 on amputation rates. METHODS: A retrospective review of lower limb institution-wide amputations was conducted at Northwell Health from January 2020 to January 2021. The amputation rates during the COVID-19 shutdown period were compared to the pre-pandemic, post-shutdown, and reopening period. RESULTS: The pre-pandemic period had 179 amputations, of which 8.38% were proximal. 86 amputations were performed during shutdown, with a greater proportion being proximal (25.58%, p=0.0009). Following the shutdown period, amputations returned to baseline. The proportion of proximal amputations during post-shutdown was 18.5% and during reopening was 12.06%. Patients had 4.89 times higher odds of undergoing a proximal amputation during the shutdown period. CONCLUSIONS: The effect of COVID-19 on amputation rates demonstrates an increase in proximal amputation during the initial shutdown. This study suggests an indirect negative effect of COVID-19 hospital restrictions on surgeries during the initial shutdown period.

To date, the establishment of high-titer stable viral packaging cells (VPCs) at large scale for gene therapeutic applications is very time- and cost-intensive. Here we report the establishment of three human suspension 293-F-derived ecotropic MLV-based VPCs. The classic stable transfection of an EGFP-expressing transfer vector resulted in a polyclonal VPC pool that facilitated cultivation in shake flasks of 100 mL volumes and yielded high functional titers of more than 1 × 106 transducing units/mL (TU/mL). When the transfer vector was flanked by transposon terminal inverted repeats (TIRs) and upon co-transfection of a plasmid encoding for the transposase, productivities could be slightly elevated to more than 3 × 106 TU/mL. In contrast and using mRNA encoding for the transposase, as a proof of concept, productivities were drastically improved by more than ten-fold exceeding 5 × 107 TU/mL. In addition, these VPC pools were generated within only 3 weeks. The production volume was successfully scaled up to 500 mL employing a stirred-tank bioreactor (STR). We anticipate that the stable transposition of transfer vectors employing transposase transcripts will be of utility for the future establishment of high-yield VPCs producing pseudotype vector particles with a broader host tropism on a large scale.

Published: April 2023

Porous tantalum (Ta) implants have been developed and clinically applied as high-quality implant biomaterials in the orthopedics field because of their excellent corrosion resistance, biocompatibility, osteointegration, and bone conductivity. Porous Ta allows fine bone ingrowth and new bone formation through the inner space because of its high porosity and interconnected pore structure. It contributes to rapid bone integration and long-term stability of osseointegrated implants. Porous Ta has excellent wetting properties and high surface energy, which facilitate the adhesion, proliferation, and mineralization of osteoblasts. Moreover, porous Ta is superior to classical metallic materials in avoiding the stress shielding effect, minimizing the loss of marginal bone, and improving primary stability because of its low elastic modulus and high friction coefficient. Accordingly, the excellent biological and mechanical properties of porous Ta are primarily responsible for its rising clinical translation trend. Over the past 2 decades, advanced fabrication strategies such as emerging manufacturing technologies, surface modification techniques, and patient-oriented designs have remarkably influenced the microstructural characteristic, bioactive performance, and clinical indications of porous Ta scaffolds. The present review offers an overview of the fabrication methods, modification techniques, and orthopedic applications of porous Ta implants.
