Published: February 2024

AbstractThe conjugated small‐molecule materials of organic solar cells have always played a crucial role in light‐harvesting, charge transport, morphology optimization, and the attainment of efficient devices. The advancement of novel materials and the understanding of underlying molecular design rules serve as the driving force for furthering efficient and stable photovoltaic devices. Among a variety of design principles, the symmetry‐breaking strategy, which is well developed in 3,9‐bis(2‐methylene‐(3‐(1,1‐dicyanomethylene)‐indanone))‐5,5,11,11‐tetrakis(4‐hexylphenyl)‐dithieno[2,3‐d:2′,3′‐d’]‐s‐indaceno[1,2‐b:5,6‐b’]dithiophene (ITIC)‐series acceptors, recently demonstrates great potential in small‐molecule acceptors and donors for realizing high power conversion efficiency. In this review, in order to give a deep insight on asymmetric strategy, the small‐molecule acceptors and donors are systematically summarized with asymmetric structure to elucidate structure‐performance relationship, molecular packing behaviors, and morphology evolution. Not only the delicate balance between open circuit voltage and short‐circuit current density, but also the reductions in charge recombination and non‐radiative recombination are considered to play the key points in improving the photovoltaic performance when the asymmetric molecule is used as host or guest materials. Finally, concise challenges and outlooks are provided for the future development and application of asymmetric molecules and symmetry‐breaking strategies.
Embracing uncertainty: The way forward in plant fossil phylogenetics
Authors: Coiro Mario 
Published: February 2024

AbstractAlthough molecular phylogenetics remains the most widely used method of inferring the evolutionary history of living groups, the last decade has seen a renewed interest in morphological phylogenetics, mostly driven by the promises that integrating the fossil record in phylogenetic trees offers to our understanding of macroevolutionary processes and dynamics and the possibility that the inclusion of fossil taxa could lead to more accurate phylogenetic hypotheses. The plant fossil record presents some challenges to its integration in a phylogenetic framework. Phylogenies including plant fossils often retrieve uncertain relationships with low support, or lack of resolution. This low support is due to the pervasiveness of morphological convergence among plant organs and the fragmentary nature of many plant fossils, and it is often perceived as a fundamental weakness reducing the utility of plant fossils in phylogenetics. Here I discuss the importance of uncertainty in morphological phylogenetics and how we can identify important information from different patterns and types of uncertainty. I also review a set of methodologies that can allow us to understand the causes underpinning uncertainty and how these practices can help us to further our knowledge of plant fossils. I also propose that a new visual language, including the use of networks instead of trees, represents an improvement on the old visualization based on consensus trees and more adequately serves phylogeneticists working with plant fossils. This set of methods and visualization tools represents an important way forward in a fundamental field for our understanding of the evolutionary history of plants.

AbstractDeveloping high connectivity (>8) three‐dimensional (3D) covalent organic frameworks (COFs) towards new topologies and functions remains a great challenge owing to the difficulty in getting high connectivity organic building blocks. This however represents the most important step towards promoting the diversity of COFs due to the still limited dynamic covalent bonds available for constructing COFs at this stage. Herein, highly connected phthalocyanine‐based (Pc‐based) 3D COFs MPc‐THHI‐COFs (M=H2, Ni) were afforded from the reaction between 2,3,9,10,16,17,23,24‐octacarboxyphthalocyanine M(TAPc) (M=H2, Ni) and 5,5′,5′′,5′′′,5′′′′,5′′′′′‐(triphenylene‐2,3,6,7,10,11‐hexayl)hexa(isophthalohydrazide) (THHI) with 12 connecting sites. Powder X‐ray diffraction analysis together with theoretical simulations and transmission electron microscopy reveals their crystalline nature with an unprecedented non‐interpenetrated shp topology. Experimental and theoretical investigations disclose the broadened visible light absorption range and narrow optical band gap of MPc‐THHI‐COFs. This in combination with their 3D nanochannels endows them with efficient photocatalysis performance for H2O2 generation from O2 and H2O via 2e− oxygen reduction reaction and 2e− water oxidation reaction under visible‐light irradiation (λ >400 nm). This work provides valuable result for the development of high connectivity functional COFs towards diverse application potentials.
Effects of a generalized uncertainty principle on the MIT bag model equation of state
Authors: Netz‐Marzola Marcelo , Zen Vasconcellos César A. , Hadjimichef Dimiter 
Published: February 2024

AbstractThe Generalized Uncertainty Principle (GUP) is motivated by the premise that spacetime fluctuations near the Planck scale impose a lower bound on the achievable resolution of distances, leading to a minimum length. Inspired by a semiclassical method that integrates the GUP into the partition function by deforming its phase space, we induce a modification on the thermodynamic quantities of the MIT bag model that we propose serves as an effective semiclassical description of deconfined quark matter in a space with minimal length. We investigate the consequences of this deformation on the zero‐temperature limit, revealing a saturation limit for the energy density, pressure, and baryon number density and an overall decrease of the thermodynamic quantities which suggests an enhanced stability against gravitational collapse. These findings extend existing research on GUP‐deformed Fermi gases. Ultimately, our description introduces the effects of quantum gravity in the equations of state for compact stars in a mathematically simple manner, suggesting the potential for extension to more complex systems.
America's urban futures: In and beyond the city
Authors: Addie Jean‐Paul D. 
Published: February 2024

AbstractThis article assesses the changing dynamics of urbanization and urbanism in the contemporary US through three lenses. First, it examines economic shifts spurred by the rise of the knowledge economy, which position higher education institutions (HEIs) as drivers of innovation and urban growth. Second, it draws attention to new metropolitan geographies. Gentrifying inner cities and the suburbanization of race, poverty, and risk indicate a need for HEIs to reappraise their institutional structures, pedagogical practices, and responsibilities as urban place‐makers. Third, the article considers (post‐)pandemic futures and calls for racial justice to frame the city as both the setting and stake of social justice movements. The analysis pays particular attention to how these socio‐spatial transformations affect the landscape of post‐secondary urban education. The result is a contradictory portrait of an urban America with diverse futures forged at the intersection of rising inequality, segregation, and a desire for a more inclusive and just future.

Published: February 2024

AbstractThe COVID‐19 pandemic illuminated the need for urban community colleges to utilize an adaptive leadership approach to thrive during times of uncertainty. Adaptive leaders encourage team members to address problems through new ways of thinking to meet organizational goals. The community college sector, especially institutions in urban environments, has utilized adaptive leadership throughout its history to best meet the needs of its students. It is against this background that urban community colleges adapted to the COVID‐19 pandemic by reconceptualizing career programs to be completed in virtual spaces, hosting COVID‐19 testing and vaccination centers on campus, and ensuring that students had access to faculty and staff in a digital learning environment. In this chapter, we highlight the importance of adaptive leadership in urban community colleges and provide examples from urban community college leaders on how they utilize adaptive leadership to meet new challenges.

AbstractEvery host species and organism provides a unique environmental niche contributing to the overall diversity of microbial ecosystems from the intestine of an animal to the oceans and forests of our planet. The study of host–microbiota interactions has long focused on the well‐established effects the microbiota has on its host. In contrast, little focus has been allocated to the role of the host in these intricate interactions. However, understanding the role of the host may well be an essential key to understanding the complexity of the relationship between the host and its microbiota. In this study, we present a model in which the effects of host genes on the microbiota can be elucidated and how such genetic effects may shape host‐associated microbiota. We demonstrate a hologenomic approach implementing the CRISPR/Cas system in the zebrafish model to combine the effects of a host gene with 16S metabarcoding and metabolomics data. We show that knocking out the gene coding for the rate‐limiting enzyme in melanogenesis, tyrosinase (tyr), correlates with changes in the intestinal microbiota of zebrafish and differences in the abundance of specific metabolites illustrating the value of our model for studying the impact of host genes on the composition and function of the intestinal microbiota.

AbstractThe sediment microbial fuel cell (SMFC) sensors using cathode as sensing element exhibited attractive prospects for online and in‐situ monitoring. However, the sensing performance of SMFC sensors to different types of contaminants was seldom reported. In this study, SMFCs were constructed in stimulated wetland to sense five types of contaminants, including oxidative heavy metals (Cu2+ and Cr6+), non‐oxidative heavy metals (Ni2+ and Zn2+), salt (NaCl), acid (HCl), and alkali (NaOH). The addition of Cu2+, Cr6+ or H+ triggered voltage peaks whereas the voltage dropped immediately following the addition of OH−. The addition of Ni2+ and Zn2+ did not trigger any obvious peaks. The NaCl solutions caused slight voltage peaks which were not increased with increasing concentrations. X‐ray photoelectron spectroscopy (XPS) illustrated the reduction of Cu2+ and Cr6+ to elemental Cu and Cr3+ on the cathodic surface, indicating the contaminants that promote or inhibit electron consumption on cathode would cause voltage peaks or drops. The addition of heavy metals, OH− and NaCl significantly increased Simpson's diversity whereas Cu2+, Cr6+ and OH− significantly decreased the abundance of exoelectrogenic bacteria‐associated genera in the top‐layer soil. However, the influence of the contaminants on the abundance and diversity was attenuated in the middle and bottom layers, indicating that the exoelectrogenic bacteria could to some extent withstand these contaminants and guarantee the operation of the SMFC sensors.
Recruiting grape‐isolated antagonistic yeasts for the sustainable bio‐management of Botrytis cinerea on grapes
Authors: Oztekin Sebahat , Karbancioglu‐Guler Funda 
Published: February 2024

AbstractBotrytis cinerea is the causative agent of grey mould disease in grapes, which was linked to significant postharvest losses. This study examined three grape‐isolated yeasts (Metschnikowia aff. fructicola, Metschnikowia pulcherrima, and Hansenispora uvarum) through in vitro and in vivo tests on detached grape berries against grey mould, as well as the elucidation of their possible mechanisms of action. The antifungal mechanism of action of yeasts was determined by the lytic enzyme activity, inhibition of spore germination, biofilm activity, iron depletion, diffusible metabolites, wound‐site colonisation, mycocin, and volatile organic compounds (VOCs) production. The highest in vitro efficacy (83.13%) was observed on M. aff. fructicola, followed by M. pulcherrima (82.10%) and H. uvarum (71.66%). Metschnikowia yeasts exhibited comparable enzyme activities, including protease, β‐1,3 glucanase, gelatinase chitinase, and cellulase, while H. uvarum had a poor enzymatic activity with chitinase and gelatinase. M. aff. fructicola showed relatively higher iron depletion activity than M. pulcherrima, while M. pulcherrima outperformed via diffusible metabolites. All yeast cultures significantly reduced spore germination by at least 86%. Overall, M. aff. fructicola exhibited the highest biocontrol activity with its iron depletion, inhibition of conidial germination, biofilm formation, VOCs, and well colonisation on grape berries. M. aff. fructicola 1‐UDM outperformed all other yeasts by significantly reducing disease incidence and lesion diameter values (93.4% and 94.3%, respectively). Remarkably, H. uvarum VOCs demonstrated potential as a biofumigant for suppressing grey mould. All yeasts are well adapted to their ecological niche to bio‐protect grapes from grey mould disease.

Meta‐analysis was performed.ResultsThere were 146 studies included in the systematic review. Rates of events were collected in the overall group, those with chemoprophylaxis, and those that underwent surgery, radiation, or chemotherapy. Of 1 184 160 patients, 4.3% had a vascular event. Radiation therapy had highest risk of overall events and stroke when compared to surgery and chemotherapy. Chemotherapy had a higher risk of stroke and overall events when compared to surgery.ConclusionsVascular events occur in 4%–5% of patients with head and neck cancer. Our data does not support the use of routine anticoagulation. Patients undergoing radiation therapy had the highest frequency of events.

AbstractBackground and AimsEndometriosis is a common reason for infertility and poor outcomes of assisted reproductive technology (ART). Inflammation is involved in the pathogenesis of this disease. The presence of microorganisms in women with endometriosis may increase levels of inflammatory markers. The purpose of this study is to determine the relationship between the presence of bacteria in the follicular fluid with the inflammatory markers of the complete blood count (CBC) and the outcomes of in vitro fertilization (IVF) in women with endometriosis.MethodsThis case–control study was conducted on 74 patients undergoing IVF, referred to Al‐Zahra Hospital in Rasht (Iran) in 2021. The patients were divided into two case groups including 37 women with endometrioma and the control group, including 37 infertile women with a male factor and normal ultrasound. In total, 74 follicular fluids were collected from the case and control groups and were cultured in the laboratory. The relationship between culture results with IVF outcomes and the levels of CBC inflammatory markers including the number of white blood cells (WBCs), lymphocytes, neutrophils, neutrophil‐to‐lymphocyte ratio (NLR), lymphocyte‐to‐monocyte ratio (LMR), and platelet‐to‐lymphocyte ratio (PLR), erythrocyte sedimentation rate (ESR), and c‐reactive protein (CRP) was analyzed.ResultsThere was no significant statistical difference between the frequency of bacteria present in the follicular fluid (p = 0.861), the mean rate of fertilization (p = 0.363), the frequency of CRP (p = 0.999), and the mean WBCs, lymphocytes, neutrophils, NLR, LMR, and PLR in the two groups. There was a significant statistical difference between the mean number of oocytes of metaphase II (p = 0.034) and the mean ESR (p = 0.018) in the two groups.ConclusionsIt seems necessary to evaluate follicular fluid as a biological substance that is considered an optimal factor for predicting oocyte quality, fertilization rate, embryo quality, and the success rate of ART.

IntroductionLow‐dose‐rate brachytherapy is performed for localized prostate cancer. We report the first case of a bladder stone encompassing the seed migrated into the bladder in a patient treated with low‐dose‐rate brachytherapy.Case presentationA man was diagnosed with prostate cancer and underwent low‐dose‐rate brachytherapy. After 2 months, dysuria occurred, and ultrasonography revealed a needle‐shaped high‐intensity protruding from the prostate into the bladder. Cystoscopy examination found a seed link connector. With the possibility of natural dissolution of the seed link, careful observation was chosen. However, 16 months later, hematuria occurred, and an X‐ray revealed a bladder stone encompassing the seed. Compared with the X‐ray right after seeding, the seed located near the right bladder neck had fallen. The seed was removed by transurethral bladder lithotripsy.ConclusionSeeds should be carefully located within the prostate, otherwise a bladder stone may be formed encompassing the seed.

AbstractBackgroundMuscle and bone are physiologically interconnected, but joint changes of muscle and bone with aging, and whether the muscle‐bone changes are different by sex and by country has been little studied. We examined longitudinal associations of bone mineral density (BMD) and muscle mass or muscle strength in community‐dwelling 65 years or older in the United States and Japan.MethodsThe present analytic sample included 1129 women and men from the Baltimore Longitudinal Study of Aging (BLSA) (mean age, 74.5 ± 7.5 years; women, 49.8%) and 1998 women and men from the National Institute for Longevity Sciences‐Longitudinal Study of Aging (NILS‐LSA) (mean age, 70.0 ± 4.5 years; women, 51.4%). Median follow‐up was 4.6 (min‐max, 0–15.4) years in the BLSA and 4.0 (min‐max, 0–13.4) years in the NILS‐LSA. We selected visits at which participants had BMD (whole body, pelvic, femoral neck, trochanter, and Ward's triangle BMDs) and muscle mass [appendicular lean mass, (ALM)] measured by DXA scan. In each bone site, we ran cohort‐specific bivariate linear mixed‐effects models adjusted for baseline age, sex, body height, body weight, fat mass, education year, and smoking status. Race was an additional adjustment in the BLSA. Additionally, we performed sex‐specific analyses.ResultsIn the BLSA, the rate of change in ALM positively correlated with the rate of change in the whole body (rho = 0.30, P < 0.0001) and pelvic BMD (rho = 0.24, P < 0.0001), but not in trochanter, femoral neck, or Ward's triangle BMD (P > 0.05). In the NILS‐LSA, ALM positively correlated with the rate of change in all bone sites (rho ranged from 0.20 to 0.71, P < 0.01). In women, ALM positively correlated with the rate of change in all bone sites in both cohorts (in the NILS‐LSA, rho ranged from 0.35 to 0.91, P < 0.01; in the BLSA, rho ranged from 0.26 to 0.56, P < 0.05) except for femoral neck BMD in the BLSA. In men, ALM positively correlated with pelvic, trochanter, and Ward's triangle BMD in the NILS‐LSA (rho ranged from 0.45 to 0.68, P < 0.0001), and whole body and trochanter BMD in the BLSA (both, rho = 0.20, P < 0.05).ConclusionsMuscle loss co‐occurred with bone loss in both cohorts, but the association in the NILS‐LSA tended to be stronger than in the BLSA, and the association was higher in women than in men, implying that the association may differ by sex and country.
