CHICHEN ITZA AND ITS ECONOMY AT THE END OF THE CLASSIC PERIOD: TRIBUTE, CENTRALIZED REDISTRIBUTION, AND MARITIME STATIONS
Authors: Cobos Rafael
Published: March 2023

Studies of the ancient economy associated with the Classic and Postclassic periods of Maya civilization show that, in order to explain it, the market economy model has been widely used, where economic transactions were carried out in marketplaces. In this type of economy, goods are exchanged based on an agreed value that takes into account supply and demand. However, other types of exchange, such as tribute and centralized redistribution, could have been used in those transactions instead of a market economy. This article analyzes the role that tribute and centralized redistribution may have played during the heyday of Chichen Itza between the tenth and eleventh centuries. This site seems to have used its powerful military supremacy to extract tribute from sites and regions it conquered militarily and politically as they experienced their collapse. In addition, the archaeological evidence suggests that Chichen Itza made political as well as economic alliances in different regions of the Maya Lowlands in order to obtain sumptuous goods. These commodities were used by members of the elite to reinforce the power structure and consolidate social relations among the different individuals who inhabited that community located in northern Yucatan.
Literary Ecology in Nineteenth-Century Bengal
Authors: Ghosh Sutanuka
Published: March 2023

The project Literary Ecology in Nineteenth-Century Bengal has been investigating the representation and interpretation of the relationship between humans and nonhuman nature in the context of the radical transformations in the physical and ideological landscapes that characterized nineteenth-century Bengal. We are examining the diverse political, economic and scientific influences that shaped the narrative trajectory of literary ecology in nineteenth-century Bengal, which subsequently went on to influence understandings, representations, and interpretations of ecological concerns in the twentieth century.
Located by Victorianism
Authors: Smith Faith
Published: March 2023

This essay on the “English-speaking Caribbean” reflects on pasts that have not passed but have instead been passed on, for example in gestures of erasure, silence, or genteel substitution, whether in the Victorian novel or the twenty-first-century novel that insistently returns to the past, or in the rhetoric of law and statecraft. In addition, I consider how Victorianism has reproduced itself in postcolonial Caribbean and British life, with consequences for Black intimacy and kinship.
When Reading Matters
Authors: Ward Megan
Published: March 2023

One way to tell the story of our discipline is as a story about reading. In the early twentieth century, in order to establish the value of literary criticism, critics used the framework of professionalism to create specialized vocabulary, professional societies, and reading methods distinguished from those of laypeople. Foundational pieces of literary criticism often pry analysis apart from the affective experiences of reading literature—our sympathy, identification, shock, or sadness. Early literary critics did so in order to privilege literature's patterns and structures to argue, implicitly or explicitly, that literature is art, not life. In other words, reading literary description isn't a substitute for experiencing sensory perception of those settings, people, or objects. Fictional characters’ affective lives—and our responses to those lives—aren't a way to understand our own subjecthood.
-CONNECTEDNESS OF MODULI OF VECTOR BUNDLES ON A CURVE
Authors: Hogadi Amit , Yadav Suraj
Published: March 2023

In this note, we prove that the moduli stack of vector bundles on a curve with a fixed determinant is
${\mathbb A}^1$
-connected. We obtain this result by classifying vector bundles on a curve up to
${\mathbb A}^1$
-concordance. Consequently, we classify
${\mathbb P}^n$
-bundles on a curve up to
${\mathbb A}^1$
-weak equivalence, extending a result in [3] of Asok-Morel. We also give an explicit example of a variety which is
${\mathbb A}^1$
-h-cobordant to a projective bundle over
${\mathbb P}^2$
but does not have the structure of a projective bundle over
${\mathbb P}^2$
, thus answering a question of Asok-Kebekus-Wendt [2].

Published: March 2023

Short-channel Gallium Nitride (GaN) high-electron-mobility transistors (HEMTs) often utilize T-shape gates due to their large gate-line cross-sectional area and subsequent fMAX increase. In this paper, we report the linearity trade-offs associated with varying the T-gate geometries of AlGaN/GaN HEMTs on Si, specifically the gate extensions which serve as field plates and their impact on the large-signal performance. Small-signal characterization and modeling, in addition to TCAD, provide initial guidelines for the optimal dimensions for the gate field plates using the ratio of fT and the product of the gate resistance and the gate-to-drain capacitance. We utilize various characterization methods, including 6 GHz non-linear vector network analyzer characterization in addition to load-pull, to quantify the amplitude and phase distortion and their subsequent impact on the large-signal metrics of the devices under differing matching conditions and bias points. We deduce that the influence of the gate field plates on the amplitude and phase distortion is non-negligible, particularly under matched conditions.
Hyper beamforming with single-sideband time-modulated phased arrays for automotive radar
Authors: Ma Yue , Miao Chen , Wu Wen
Published: March 2023

In this study, a single-sideband time-modulated phased array (STMPA)-based hyper beamforming (HBF) system for automobile radar is suggested. The left beam and the right beam are generated once the improved STMPA is split into two subarrays. The HBF method is then used to produce the hyper beam. The switching sequence may be adjusted to generate the hyper beam in the desired direction. This study's benefits may be summed up as follows: (1) The hyper beam's sidelobe level is lower and its beamwidth is narrower than the conventional beam, which can help with estimating the direction of arrival. (2) The HBF can be achieved over a very wide scanning range. (3) With time as an additional controllable variable, the system's control mode is flexible and only two channels are needed, which lowers the system's cost and complexity. The effectiveness of the algorithm is tested through simulation, and the results highlight the system's potential when used with automobile radar.

Folate and choline are methyl donor nutrients that may play a role in fetal brain development. Animal studies have reported that prenatal folate and choline supplementation are associated with better cognitive outcomes in offspring and that these nutrients may interact and affect brain development. Human studies that have investigated associations between maternal prenatal folate or choline levels and neurodevelopmental outcomes have reported contradictory findings and no human studies have examined the potential interactive effect of folate and choline on children’s neurodevelopment. During the second trimester of pregnancy, maternal red blood cell folate was measured from blood samples and choline intake was estimated using a 24-h dietary recall in 309 women in the APrON cohort. At 3–5 years of age, their children’s neurodevelopment was assessed using the Wechsler Preschool and Primary Scales of Intelligence – Fourth EditionCND, NEPSY-II language and memory subtests, four behavioral executive function tasks, and the Movement Assessment Battery for Children – Second Edition. Adjusted regressions revealed no associations between maternal folate and choline levels during pregnancy and most of the child outcomes. On the Dimensional Change Card Sort, an executive function task, there was an interaction effect; at high levels of choline intake (i.e., 1 SD above the mean; 223.03 mg/day), higher maternal folate status was associated with decreased odds of receiving a passing score (β = −0.44; 95%CI −0.81, −0.06). In conclusion, maternal folate status and choline intake during the second trimester of pregnancy were not associated with children’s intelligence, language, memory, or motor outcomes at 3–4 years of age; however, their interaction may have an influence children’s executive functions.

Published: March 2023

Summary: Background: Dysfunction in arteriovenous (AV) access is a common reason for subsequent intervention. To evaluate the results of endovascular treatment of AV access lesions using cutting balloon (CB) and drug-coated balloon (DCB) angioplasty compared to standard treatment using plain-old balloon angioplasty (POBA). Patients and methods: Patients who retrospectively were selected from a prospectively maintained database. Primary endpoint was primary patency rate at the target lesion up to 12 months after index procedure. Secondary endpoints were the acute treatment success, the “bail out” stent rate, primary patency at 6 months, freedom from target lesion revascularization (TLR), AV access replacement and surgical revision during a follow-up period up to 12 months, and all-cause mortality rate stratified to patients treated with and without DCB. Results: One hundred and eighty-four patients met the inclusion criteria. POBA as stand alone or combined with DCB angioplasty was performed in 71 patients (38.6%), CB in 54 patients (29.3%), and in 59 patients (32.1%), both CB and DCB were used. Primary patency rate at 12 months was 31.6% for the POBA/DCB-group, 52.3% for the CB-group, and 64.8% for the CB/DCB-group, respectively. In total, 80 patients (51.6%) had a TLR including endovascular or surgical revision, or a shunt replacement. All-cause mortality at 12 months was 7.2% in the DCB group and 9.1% in the group of patients treated without a DCB (p=0.747). Conclusions: The use of CB seems to be crucial for a better outcome. The combination of CB and DCB achieves the best patency results at mid-term.

Small molecule metabolites: discovery of biomarkers and therapeutic targets
Authors: Qiu Shi , Cai Ying , Yao Hong , Lin Chunsheng , Xie Yiqiang , Tang Songqi , Zhang Aihua
Published: March 2023

Metabolic abnormalities lead to the dysfunction of metabolic pathways and metabolite accumulation or deficiency which is well-recognized hallmarks of diseases. Metabolite signatures that have close proximity to subject’s phenotypic informative dimension, are useful for predicting diagnosis and prognosis of diseases as well as monitoring treatments. The lack of early biomarkers could lead to poor diagnosis and serious outcomes. Therefore, noninvasive diagnosis and monitoring methods with high specificity and selectivity are desperately needed. Small molecule metabolites-based metabolomics has become a specialized tool for metabolic biomarker and pathway analysis, for revealing possible mechanisms of human various diseases and deciphering therapeutic potentials. It could help identify functional biomarkers related to phenotypic variation and delineate biochemical pathways changes as early indicators of pathological dysfunction and damage prior to disease development. Recently, scientists have established a large number of metabolic profiles to reveal the underlying mechanisms and metabolic networks for therapeutic target exploration in biomedicine. This review summarized the metabolic analysis on the potential value of small-molecule candidate metabolites as biomarkers with clinical events, which may lead to better diagnosis, prognosis, drug screening and treatment. We also discuss challenges that need to be addressed to fuel the next wave of breakthroughs.
Statistical performance indicators and index—a new tool to measure country statistical capacity
Authors: Dang Hai-Anh H. , Pullinger John , Serajuddin Umar , Stacy Brian
Published: March 2023

Strong statistical capacity is a prerequisite for producing reliable statistics that helps monitor a country’s governance and economic performance. This is particularly relevant for a large number of poorer countries, which have weaker statistical capacity but have to rely more on these statistics for various objectives such as monitoring poverty reduction or reporting to international donors. We present the Statistical Performance Indicators and Index (SPI) as the World Bank’s new official tool to measure country statistical capacity. The SPI is conceptually motivated, builds on a mathematical foundation, and significantly expands the number of indicators and the number of covered countries compared to its predecessor. The new index has a strong correlation with other common development indicators such as GDP per capita, governance, human capital, poverty, and inequality. It can also accommodate future improvements as the global data landscape evolves.
Diseased and healthy murine local lung strains evaluated using digital image correlation

Published: March 2023

Tissue remodeling in pulmonary disease irreversibly alters lung functionality and impacts quality of life. Mechanical ventilation is amongst the few pulmonary interventions to aid respiration, but can be harmful or fatal, inducing excessive regional (i.e., local) lung strains. Previous studies have advanced understanding of diseased global-level lung response under ventilation, but do not adequately capture the critical local-level response. Here, we pair a custom-designed pressure–volume ventilator with new applications of digital image correlation, to directly assess regional strains in the fibrosis-induced ex-vivo mouse lung, analyzed via regions of interest. We discuss differences between diseased and healthy lung mechanics, such as distensibility, heterogeneity, anisotropy, alveolar recruitment, and rate dependencies. Notably, we compare local and global compliance between diseased and healthy states by assessing the evolution of pressure-strain and pressure–volume curves resulting from various ventilation volumes and rates. We find fibrotic lungs are less-distensible, with altered recruitment behaviors and regional strains, and exhibit disparate behaviors between local and global compliance. Moreover, these diseased characteristics show volume-dependence and rate trends. Ultimately, we demonstrate how fibrotic lungs may be particularly susceptible to damage when contrasted to the strain patterns of healthy counterparts, helping to advance understanding of how ventilator induced lung injury develops.

Genomic imprinting predominantly occurs in the placenta and brain. Few imprinted microRNAs have been identified in the brain, and their functional roles in the brain are not clear. Here we show paternal, but not maternal, expression of MIR125B2 in human but not mouse brain. Moreover, Mir125b-2m−/p− mice showed impaired learning and memory, and anxiety, whose functions were hippocampus-dependent. Hippocampal granule cells from Mir125b-2m−/p− mice displayed increased neuronal excitability, increased excitatory synaptic transmission, and decreased inhibitory synaptic transmission. Glutamate ionotropic receptor NMDA type subunit 2A (Grin2a), a key regulator of synaptic plasticity, was physically bound by miR-125b-2 and upregulated in the hippocampus of Mir125b-2m−/p− mice. Taken together, our findings demonstrate MIR125B2 imprinted in human but not mouse brain, mediated learning, memory, and anxiety, regulated excitability and synaptic transmission in hippocampal granule cells, and affected hippocampal expression of Grin2a. Our work provides functional mechanisms of a species-specific imprinted microRNA in the brain.
Rickettsial DNA and a trans-splicing rRNA group I intron in the unorthodox mitogenome of the fern Haplopteris ensiformis
Authors: Zumkeller Simon , Polsakiewicz Monika , Knoop Volker
Published: March 2023

Plant mitochondrial genomes can be complex owing to highly recombinant structures, lack of gene syntenies, heavy RNA editing and invasion of chloroplast, nuclear or even foreign DNA by horizontal gene transfer (HGT). Leptosporangiate ferns remained the last major plant clade without an assembled mitogenome, likely owing to a demanding combination of the above. We here present both organelle genomes now for Haplopteris ensiformis. More than 1,400 events of C-to-U RNA editing and over 500 events of reverse U-to-C edits affect its organelle transcriptomes. The Haplopteris mtDNA is gene-rich, lacking only the ccm gene suite present in ancestral land plant mitogenomes, but is highly unorthodox, indicating extraordinary recombinogenic activity. Although eleven group II introns known in disrupted trans-splicing states in seed plants exist in conventional cis-arrangements, a particularly complex structure is found for the mitochondrial rrnL gene, which is split into two parts needing reassembly on RNA level by a trans-splicing group I intron. Aside from ca. 80 chloroplast DNA inserts that complicated the mitogenome assembly, the Haplopteris mtDNA features as an idiosyncrasy 30 variably degenerated protein coding regions from Rickettiales bacteria indicative of heavy bacterial HGT on top of tRNA genes of chlamydial origin.

Prolactin (PRL) is elevated in B-cell-mediated lymphoproliferative diseases and promotes B-cell survival. Whether PRL or PRL receptors drive the evolution of B-cell malignancies is unknown. We measure changes in B cells after knocking down the pro-proliferative, anti-apoptotic long isoform of the PRL receptor (LFPRLR) in vivo in systemic lupus erythematosus (SLE)- and B-cell lymphoma-prone mouse models, and the long plus intermediate isoforms (LF/IFPRLR) in human B-cell malignancies. To knockdown LF/IFPRLRs without suppressing expression of the counteractive short PRLR isoforms (SFPRLRs), we employ splice-modulating DNA oligomers. In SLE-prone mice, LFPRLR knockdown reduces numbers and proliferation of pathogenic B-cell subsets and lowers the risk of B-cell transformation by downregulating expression of activation-induced cytidine deaminase. LFPRLR knockdown in lymphoma-prone mice reduces B-cell numbers and their expression of BCL2 and TCL1. In overt human B-cell malignancies, LF/IFPRLR knockdown reduces B-cell viability and their MYC and BCL2 expression. Unlike normal B cells, human B-cell malignancies secrete autocrine PRL and often express no SFPRLRs. Neutralization of secreted PRL reduces the viability of B-cell malignancies. Knockdown of LF/IFPRLR reduces the growth of human B-cell malignancies in vitro and in vivo. Thus, LF/IFPRLR knockdown is a highly specific approach to block the evolution of B-cell neoplasms.

Modeling of strongly gravitationally lensed galaxies is often required in order to use them as astrophysical or cosmological probes. With current and upcoming wide-field imaging surveys, the number of detected lenses is increasing significantly such that automated and fast modeling procedures for ground-based data are urgently needed. This is especially pertinent to short-lived lensed transients in order to plan follow-up observations. Therefore, we present in a companion paper a neural network predicting the parameter values with corresponding uncertainties of a singular isothermal ellipsoid (SIE) mass profile with external shear. In this work, we also present a newly developed pipeline glee_auto.py that can be used to model any galaxy-scale lensing system consistently. In contrast to previous automated modeling pipelines that require high-resolution space-based images, glee_auto.py is optimized to work well on ground-based images such as those from the Hyper-Suprime-Cam (HSC) Subaru Strategic Program or the upcoming Rubin Observatory Legacy Survey of Space and Time. We further present glee_tools.py, a flexible automation code for individual modeling that has no direct decisions and assumptions implemented on the lens system setup or image resolution. Both pipelines, in addition to our modeling network, minimize the user input time drastically and thus are important for future modeling efforts. We applied the network to 31 real galaxy-scale lenses of HSC and compare the results to traditional, Markov chain Monte Carlo sampling-based models obtained from our semi-autonomous pipelines. In the direct comparison, we find a very good match for the Einstein radius. The lens mass center and ellipticity show reasonable agreement. The main discrepancies pretrain to the external shear, as is expected from our tests on mock systems where the neural network always predicts values close to zero for the complex components of the shear. In general, our study demonstrates that neural networks are a viable and ultra fast approach for measuring the lens-galaxy masses from ground-based data in the upcoming era with ~105 lenses expected.

The planetary system around the naked-eye star v2 Lupi (HD 136352; TOI-2011) is composed of three exoplanets with masses of 4.7, 11.2, and 8.6 Earth masses (M⊕). The TESS and CHEOPS missions revealed that all three planets are transiting and have radii straddling the radius gap separating volatile-rich and volatile-poor super-earths. Only a partial transit of planet d had been covered so we re-observed an inferior conjunction of the long-period 8.6 M⊕ exoplanet v2 Lup d with the CHEOPS space telescope. We confirmed its transiting nature by covering its whole 9.1 h transit for the first time. We refined the planet transit ephemeris to P = 107.1361−0.0022+0.0019 days and Tc = 2459009.7759−0.0096+0.0101 BJDTDB, improving by ~40 times on the previously reported transit timing uncertainty. This refined ephemeris will enable further follow-up of this outstanding long-period transiting planet to search for atmospheric signatures or explore the planet’s Hill sphere in search for an exomoon. In fact, the CHEOPS observations also cover the transit of a large fraction of the planet’s Hill sphere, which is as large as the Earth’s, opening the tantalising possibility of catching transiting exomoons. We conducted a search for exomoon signals in this single-epoch light curve but found no conclusive photometric signature of additional transiting bodies larger than Mars. Yet, only a sustained follow-up of v2 Lup d transits will warrant a comprehensive search for a moon around this outstanding exoplanet.
