Published: March 2024

Background.
Recurrence of glomerulonephritis (GN) is a significant contributor to long-term allograft failure among kidney transplant recipients (KTRs) with kidney failure because of GN. Accumulating evidence has revealed the role of vitamin D in both innate and adaptive immunity. Although vitamin D deficiency is common among KTRs, the association between 25-hydroxyvitamin D (25[OH]D) and GN recurrence in KTRs remains unclear.

Methods.
We analyzed data from KTRs with kidney failure caused by GN who received a transplant at our center from 2000 to 2019 and had at least 1 valid posttransplant serum 25(OH)D measurement. Survival analyses were performed using a competing risk regression model considering other causes of allograft failure, including death, as competing risk events.

Results.
A total of 67 cases of GN recurrence were identified in 947 recipients with GN followed for a median of 7.0 y after transplant. Each 1 ng/mL lower serum 25(OH)D was associated with a 4% higher hazard of recurrence (subdistribution hazard ratio [HR]: 1.04; 95% confidence interval [CI], 1.01-1.06). Vitamin D deficiency (≤20 ng/mL) was associated with a 2.99-fold (subdistribution HR: 2.99; 95% CI, 1.56-5.73) higher hazard of recurrence compared with vitamin D sufficiency (≥30 ng/mL). Results were similar after further adjusting for concurrent urine protein–creatinine ratio, serum albumin, and estimated glomerular filtration rate (eGFR).

Conclusions.
Posttransplant vitamin D deficiency is associated with a higher hazard of GN recurrence in KTRs. Further prospective observational studies and clinical trials are needed to determine any causal role of vitamin D in the recurrence of GN after kidney transplantation. More in vitro and in vivo experiments would be helpful to understand its effects on autoimmune and inflammation processes.
An outbreak of canine coronavirus type 2 in captive snow leopards(Panthera uncia)demonstrates a possible role for felids as mixing vessels for alphacoronaviruses

AbstractCoronaviruses are endemic and can cause disease in a wide range of domestic animal and wildlife species. The virus speciesAlphacoronavirus-1comprises a set of diverse viruses that are highly recombinogenic, including feline coronavirus type 2 (FCoV-2), which is a recombinant genotype of feline coronavirus type 1 (FCoV-1) and canine coronavirus type 2 (CCoV-2). Co-infection within a host promotes viral recombination; thus, to understand the origin of novel variants, it is crucial to identify hosts that can be infected with multiple alphacoronaviruses. The receptor for FCoV-2 and CCoV-2 is aminopeptidase N (APN), with the APN of the domestic cat(Felis catus)allowing entry of FCoV-2, CCoV-2, and other alphacoronaviruses. As wild felids are genetically closely related to the domestic cat, they may also be susceptible to these alphacoronaviruses. However, to date, natural infection with CCoV-2 has been reported exclusively in canids, not in felids. In this study, we retrospectively investigated a localized outbreak of enteritis in three captive snow leopards (Panthera uncia)at the Bronx Zoo (New York City, U.S.). Whole genome sequencing revealed shedding of CCoV-2 in the feces of the sick leopards. Phylogenetic analyses revealed it is related to highly pathogenic variants of CCoV-2 circulating in the U.S. and Europe. Comparative genetic analyses of the APN gene from five Asian wild felids, including the snow leopard, revealed a high percentage of identity to the APN of the domestic cat (>95.7%). These results emphasize the central role of domestic and wild felids in the emergence of recombinant alphacoronavirus.

ABSTRACTAimsThe clinical manifestation of type 2 diabetes (T2D) varies across populations. We compared the phenotypic characteristics of Black Africans and White Europeans with recently diagnosed T2D to understand the ethnic differences in the manifestation of T2D.MethodsWe searched Medline, EMBASE, CINAHL, Google Scholar, African Index Medicus, and Global Health for studies reporting information on phenotypic characteristics in Black Africans and White Europeans with recently diagnosed T2D.ResultsA total of 26 studies were included in this systematic review. Of these, 12 studies and 14 studies were conducted on 2,586 Black Africans in eight countries and 279,621 White Europeans in nine countries, respectively. Compared with White Europeans, Black Africans had a lower pooled mean age (49.4±4.4 years vs. 61.3±2.7 years), body mass index (26.1±2.6 kg/m2vs. 31.4±1.1 kg/m2), and a higher pooled median glycated haemoglobin (9.0 [8.0-10.3]% vs. 7.1 [6.7-7.7]%). Ugandan and Tanzanian participants had lower markers of beta-cell function and insulin resistance when compared with four White European populations.ConclusionThese findings provide evidence of the ethnic differences in the manifestation of T2D, underscoring the importance of understanding the underlying genetic and environmental factors influencing these phenotypic differences and formulating ethnic-specific approaches for managing and preventing T2D.HIGHLIGHTSEmerging evidence suggests differences in the presentation of type 2 diabetes in Black Africans and White Europeans.In this systematic review, we reported that compared with White Europeans, Black Africans presented with a lower mean age and body mass index, less co-existing hypertension, and more hyperglycaemia at the time of diagnosis of type 2 diabetes.Compared with some White European populations, Ugandan and Tanzanian participants presented with features of pancreatic beta-cell dysfunction and less insulin resistance.
Probabilistic Interpolation of Quantum Rotation Angles
Authors: Koczor Bálint , Morton John J. L. , Benjamin Simon C. 
Published: March 2024

Quantum computing requires a universal set of gate operations; regarding gates as rotations, any rotation angle must be possible. However a real device may only be capable of B bits of resolution, i.e., it might support only 2B possible variants of a given physical gate. Naive discretization of an algorithm’s gates to the nearest available options causes coherent errors, while decomposing an impermissible gate into several allowed operations increases circuit depth. Conversely, demanding higher B can greatly complexify hardware. Here, we explore an alternative: probabilistic angle interpolation (PAI). This effectively implements any desired, continuously parametrized rotation by randomly choosing one of three discretized gate settings and postprocessing individual circuit outputs. The approach is particularly relevant for near-term applications where one would in any case average over many runs of circuit executions to estimate expected values. While PAI increases that sampling cost, we prove that (a) the approach is optimal in the sense that PAI achieves the least possible overhead and (b) the overhead is remarkably modest even with thousands of parametrized gates and only seven bits of resolution available. This is a profound relaxation of engineering requirements for first generation quantum computers where even 5–6 bits of resolution may suffice and, as we demonstrate, the approach is many orders of magnitude more efficient than prior techniques. Moreover we conclude that, even for more mature late noisy intermediate-scale quantum era hardware, no more than nine bits will be necessary.

Autonomous flight performance optimization of fixed-wing unmanned aerial vehicle with morphing wingtip
Authors: Oktay Tugrul , Eraslan Yüksel 
Published: March 2024

Purpose
The purpose of this paper is to improve autonomous flight performance of a fixed-wing unmanned aerial vehicle (UAV) via simultaneous morphing wingtip and control system design conducted with optimization, computational fluid dynamics (CFD) and machine learning approaches.

Design/methodology/approach
The main wing of the UAV is redesigned with morphing wingtips capable of dihedral angle alteration by means of folding. Aircraft dynamic model is derived as equations depending only on wingtip dihedral angle via Nonlinear Least Squares regression machine learning algorithm. Data for the regression analyses are obtained by numerical (i.e. CFD) and analytical approaches. Simultaneous perturbation stochastic approximation (SPSA) is incorporated into the design process to determine the optimal wingtip dihedral angle and proportional-integral-derivative (PID) coefficients of the control system that maximizes autonomous flight performance. The performance is defined in terms of trajectory tracking quality parameters of rise time, settling time and overshoot. Obtained optimal design parameters are applied in flight simulations to test both longitudinal and lateral reference trajectory tracking.

Findings
Longitudinal and lateral autonomous flight performances of the UAV are improved by redesigning the main wing with morphing wingtips and simultaneous estimation of PID coefficients and wingtip dihedral angle with SPSA optimization.

Originality/value
This paper originally discusses the simultaneous design of innovative morphing wingtip and UAV flight control system for autonomous flight performance improvement. The proposed simultaneous design idea is conducted with the SPSA optimization and a machine learning algorithm as a novel approach.

Unveiling the nexus of globalization, economic growth, and environmental sustainability
Authors: Bi Kejia , Akhtar Rulia , Masud Muhammad Mehedi , Sultana Sayema , Zhao Yan , Al‐Mamun Abdullah 
Published: March 2024

AbstractMalaysia's rapid economic development, although remarkable, has resulted in a significant contribution to carbon dioxide (CO2) emissions in Southeast Asia. Despite this environmental challenge, Malaysia is actively working to reduce its carbon footprint. However, a limited understanding persists regarding how economic globalization (EGB), gross domestic products (GDP), financial development (FD), population density (PD), and energy consumption (ENC) intricately influence the country's ecological footprint (EP). To address this gap, this study examines both symmetrical and asymmetrical short‐ and long‐term impacts of EGB, GDP, FD, PD, ENC, and EP in Malaysia using Autoregressive Distributed Lag (ARDL) and nonlinear ARDL cointegration methods, analyzing data from 1984 to 2021. The findings reveal both symmetrical and asymmetrical long‐term relationships between these variables and the ecological footprint, particularly concerning financial development. The results indicate that, as financial development increases, there is a reduction in Malaysia's ecological footprint. This implies that a more developed financial sector may contribute to environmentally sustainable practices or investments. The study's revelation that economic globalization is associated with an increase in Malaysia's ecological footprint raises important considerations. This finding may prompt a closer examination of the environmental consequences of global economic integration, emphasizing the need for sustainable development practices. The acknowledgment that both positive and negative changes in economic globalization led to decreased ecological footprints adds complexity to the relationship. This suggests that not all aspects of economic globalization have uniformly negative ecological consequences. Understanding these nuances is crucial for formulating balanced and informed environmental policies. These findings carry significant policy implications. Policymakers may need to consider the dual impact of economic globalization and the beneficial role of financial development in crafting effective environmental policies. Incorporating environmental considerations into economic planning can help strike a balance between economic development and ecological conservation.
From vacancy to verdancy? The impact of land options on the timing of vacant lot investment
Authors: Lin Desen 
Published: March 2024

AbstractLand vacancy is a persistent phenomenon leading to various socioeconomic issues in postindustrial cities. We examine the relationship between the timing of vacant lot investment and land options and compare two investment options using a quasi‐experimental design: housing investment that develops vacant lots into housing, and greening investment that converts vacant lots into gardens and reserves redevelopment options. By compiling a unique lot‐level time‐to‐event dataset based on a large‐scale vacant lot greening program in Philadelphia, we address the questions of whether and how introducing the option of greening investment to vacant lots can expedite initial investment and reduce vacancy. With the greening option, initial investment on vacant lots becomes less irreversible, thus reducing time in vacancy by 50% and elevating the hazard rate of investment by 80%. We test for the presence of the real options channel, identifying a decelerating (accelerating) effect of price uncertainty (price growth rate) on the timing of housing investment and insignificant effects of the factors on the timing of greening investment. Our findings suggest that vacant lot greening as an anti‐blight strategy is more effective to expedite investment in neighborhoods with elevated uncertainty, subdued growth rate, moderately lower income, and heightened vacancy.
