Global trends in the development of agricultural robotics
Authors: Starostin I A , Eshchin A V , Davydova S A 
Published: February 2023

Abstract
Agriculture is one of the most difficult and unpredictable industries. Despite this, technological advances in related industries can significantly reduce the negative impact of external factors by improving agricultural technologies and agricultural equipment, including through the introduction of unmanned mobile energy vehicles and robotic platforms for performing various agricultural operations. The interest of the scientific community in research on robotic systems for agricultural purposes is growing every year. Most of the reviewed publications are devoted to the development and improvement of computer vision systems, a description of the design of the developed robots and the results of their tests, as well as the development of autonomous control systems for robotic platforms, navigation and communication systems. At the same time, not a single solution for the development of agricultural robotic systems has currently reached the level of an economically accessible industrial design. This is due primarily to the high complexity and cost of development, applied technological solutions and equipment. The industrial introduction of agricultural robots will become possible only with the further significant development and cost reduction of the technologies and components used in them.
Advantages and challenges of self-assembled monolayer as a hole-selective contact for perovskite solar cells
Authors: Wang Songran , Guo Huanxin , Wu Yongzhen 
Published: February 2023

Abstract
Charge-transporting layers (CTLs) are important in determining the performance and stability of perovskite solar cells (PSCs). Recently, there has been considerable use of self-assembled monolayers (SAMs) as charge-selective contacts, especially for hole-selective SAMs in inverted PSCs as well as perovskite involving tandem solar cells. The SAM-based charge-selective contact shows many advantages over traditional thin-film organic/inorganic CTLs, including reduced cost, low optical and electric loss, conformal coating on a rough substrate, simple deposition on a large-area substrate and easy modulation of energy levels, molecular dipoles and surface properties. The incorporation of various hole-selective SAMs has resulted in high-efficiency single junction and tandem solar cells. This topical review summarizes both the advantages and challenges of SAM-based charge-selective contacts, and discusses the potential direction for future studies.

Published: February 2023

Abstract
Recurrent events—outcomes that an individual can experience repeatedly over the course of follow-up—are common in epidemiologic and health services research. Studies involving recurrent events often focus on time to first occurrence or on event rates, which assume constant hazards over time. In this paper, we contextualize recurrent event parameters of interest using counterfactual theory in a causal inference framework and describe an approach for estimating a target parameter referred to as the mean cumulative count. This approach leverages inverse probability weights to control measured confounding with an existing (and underutilized) nonparametric estimator of recurrent event burden first proposed by Dong et al. in 2015. We use simulations to demonstrate the unbiased estimation of the mean cumulative count using the weighted Dong-Yasui estimator in a variety of scenarios. The weighted Dong-Yasui estimator for the mean cumulative count allows researchers to use observational data to flexibly estimate and contrast the expected number of cumulative events experienced per individual by a given time point under different exposure regimens. We provide code to ease application of this method.
Dockey: a modern integrated tool for large-scale molecular docking and virtual screening

Published: February 2023

AbstractMolecular docking is a structure-based and computer-aided drug design approach that plays a pivotal role in drug discovery and pharmaceutical research. AutoDock is the most widely used molecular docking tool for study of protein–ligand interactions and virtual screening. Although many tools have been developed to streamline and automate the AutoDock docking pipeline, some of them still use outdated graphical user interfaces and have not been updated for a long time. Meanwhile, some of them lack cross-platform compatibility and evaluation metrics for screening lead compound candidates. To overcome these limitations, we have developed Dockey, a flexible and intuitive graphical interface tool with seamless integration of several useful tools, which implements a complete docking pipeline covering molecular sanitization, molecular preparation, paralleled docking execution, interaction detection and conformation visualization. Specifically, Dockey can detect the non-covalent interactions between small molecules and proteins and perform cross-docking between multiple receptors and ligands. It has the capacity to automatically dock thousands of ligands to multiple receptors and analyze the corresponding docking results in parallel. All the generated data will be kept in a project file that can be shared between any systems and computers with the pre-installation of Dockey. We anticipate that these unique characteristics will make it attractive for researchers to conduct large-scale molecular docking without complicated operations, particularly for beginners. Dockey is implemented in Python and freely available at https://github.com/lmdu/dockey.

Published: February 2023

Abstract

Objectives
The objective of this study is to explore the characteristics of the subset of patients with hematologic malignancies (HMs) who had little to no change in SARS-CoV-2 spike antibody index value levels after a third mRNA vaccine dose (3V) and to compare the cohort of patients who did and did not seroconvert post-3V to get a better understanding of the demographics and potential drivers of serostatus.

Study design
This retrospective cohort study analyzed SARS-CoV-2 spike IgG antibody index values pre and post the 3V data on 625 patients diagnosed with HM across a large Midwestern United States healthcare system between 31 October 2019 and 31 January 2022.

Methods
To assess the association between individual characteristics and seroconversion status, patients were placed into two groups based on IgG antibody status pre and post the 3V dose, (−/+) and (−/−). Odds ratios were used as measures of association for all categorical variables. Logistic regressions were used to measure the association between HM condition and seroconversion.

Results
HM diagnosis was significantly associated with seroconversion status (P = 0.0003) with patients non-Hodgkin lymphoma six times the odds of not seroconverting compared with multiple myeloma patients (P = 0.0010). Among the participants who were seronegative prior to 3V, 149 (55.6%) seroconverted after the 3V dose and 119 (44.4%) did not.

Conclusion
This study focuses on an important subset of patients with HM who are not seroconverting after the COVID mRNA 3V. This gain in scientific knowledge is needed for clinicians to target and counsel these vulnerable patients.
How did the COVID-19 Pandemic Affect Palliative Care Social Work Services? A Scoping Review
Authors: Roulston Audrey , Gerson Sheri Mila , Csikai Ellen , Dobrikova Patricia 
Published: February 2023

Abstract
The SARS-CoV-2 coronavirus-19 (COVID-19) generated life-defining challenges on a global level, affecting healthcare professionals, who faced the same imminent public health threat as patients and families. Reduced face-to-face contact, wearing personal protective equipment and enforcing visitor restrictions generated moral distress in healthcare professionals, unable to provide holistic care. This scoping review explored the impact of the COVID-19 pandemic on palliative care social workers (PCSWs). PubMED, CINAHL and PsycINFO were systematically searched. Empirical studies and reflective articles about palliative care social work during the pandemic were screened. Data extraction used Arksey and O’Malley’s framework. Thematic analysis was underpinned by Braun and Clarke for identifying, analysing and reporting patterns. From 706 citations retrieved, 125 were selected for full-text review and 32 were included in the scoping review. Thematic analysis revealed three themes: (i) moral distress, (ii) transitioning and (iii) inequality. Implementing visitor restrictions caused moral distress and raised questions about their justification. Not being present at the time of death generated feelings of anger among bereaved family members. Virtual communication replaced face-to-face contact, yet improved access to Telehealth. Inequalities were illuminated and PCSWs advocated for disadvantaged populations, worked creatively to minimise suffering or stigma and supported peers.
A review of anatomical and phytolith studies of cystoliths: silica-calcium phytoliths in dicotyledonous angiosperms
Authors: Fernández Honaine Mariana , Borrelli Natalia L , Martinez Tosto Ana C 
Published: February 2023

Abstract
Cystoliths are phytoliths of silica and calcium carbonate and are produced in a few groups of dicotyledonous angiosperms. Anatomical and, more recently, phytolith studies have recorded them in different families. In the present review, we analyse and integrate both types of research to compile information about their formation and composition, their distribution in vascular plants, their relation with anatomy and systematics and their potential roles in plant tissues. We also include analyses of specimens belonging to families having poorly-known cystolith information. According to our review, cystoliths can be considered to be Si-Ca phytoliths. They are well described in eight families, and in 14 other families the information is inconclusive. The production of cystoliths is limited to dicotyledons, but there is no clear phylogenetic relation between the families that produce them. Cystolith accumulation is predominantly in the epidermis of leaves and/or in parenchymatic rays of woods. Diverse roles related to photosynthesis enhancement and as Ca reservoirs have been assigned to cystoliths. Knowledge of cystolith production among vascular plants is relevant for anatomical, systematic and ecological research, and also for biogeochemical studies due to their importance as a source of Ca and Si.
Exuviae Recycling Can Enhance Queen Oviposition and Colony Growth in Subterranean Termites (Blattodea: Rhinotermitidae: Coptotermes)

Abstract
Wood-feeding termites have a nitrogen-poor diet and have therefore evolved nitrogen conservation strategies. However, termite workers molt periodically, and throughout the lifetime of a colony, millions of exuviae, a nitrogen-rich resource, are produced by the colony. In Coptotermes Wasmann, workers foraging at remote feeding sites must return to the central part of the nest to molt, where the queen, king, eggs, and larvae are located. It was hypothesized that this molting-site fidelity is an efficient way to recycle nitrogen for reproduction and colony growth, as nestmates involved in exuviae consumption can directly transfer such resources to individuals engaged in reproduction (the queen) or growth (larvae). This study investigates whether incipient colonies of C. gestroi (Wasmann) can gain additional biomass when they are fed supplementary exuviae. Incipient colonies were reared in nitrogen-poor or nitrogen-rich conditions, and 0, 1, 5, or 10 exuviae were added to 3-month-old colonies. After 6.5 months, colonies reared in nitrogen-poor environments gained significantly more biomass when exuviae were added than colonies with no added exuviae. However, the addition of exuviae had no effect on colony growth for colonies reared in nitrogen-rich environments. In a second experiment, queens from colonies in which exuviae were effectively removed laid fewer eggs than queens from colonies in which exuviae were not removed. Therefore, consumption of exuviae from molting individuals by nestmates is an important part of the nitrogen recycling strategy in Coptotermes colonies, as it facilitates queen oviposition and colony growth, especially when such colonies have limited access to nitrogen-rich soils.
Aphid male wing polymorphisms are transient and have evolved repeatedly
Authors: Saleh Ziabari Omid , Li Binshuang , Hardy Nate B , Brisson Jennifer A 
Published: February 2023

AbstractPolymorphic phenotypes have long been used to examine the maintenance of genetic variation within and between species. Most studies have focused on persistent polymorphisms, which are retained across species boundaries, and their positive effects on speciation rates. Far less is known about the macroevolutionary impacts of more transient polymorphisms, which are also common. Here we investigated male wing polymorphisms in aphids. We estimated the phylogenetic history of wing states across species, along with several other traits that could affect wing evolution. We found that male wing polymorphisms are transient: they are found in only ~4% of extant species, but have likely evolved repeatedly across the phylogeny. We reason that the repeated evolution of transient polymorphisms might be facilitated by the existence of the asexual female wing plasticity, which is common across aphids, and would maintain the wing development program even in species with wingless males. We also discovered that male wingedness correlates positively with host plant alternation and host plant breadth, and that winged morphs and wing polymorphisms may be associated with higher speciation rates. Our results provide new evolutionary insights into this well-studied group and suggest that even transient polymorphisms may impact species diversification rates.
The rate of chromosomal inversion fixation in plant genomes is highly variable
Authors: Hirabayashi Kaede , Owens Gregory L 
Published: February 2023

AbstractChromosomal inversions are theorized to play an important role in adaptation by preventing recombination, but testing this hypothesis requires an understanding of the rate of inversion fixation. Here, we use chromosome-level whole-genome assemblies for 32 genera of plants to ask how fast inversions accumulate and what factors affect this rate. We find that on average species accumulate 4–25 inversions per million generations, but this rate is highly variable, and we find no correlation between sequence divergence or repeat content and the number of inversions or the proportion of genome that was inverted and only a small correlation with chromosome size. We also find that inversion regions are depleted for genes and enriched for TEs compared to the genomic background. This suggests that idiosyncratic forces, like natural selection and demography, are controlling how fast inversions fix.
Quality of Care at the End of Life: Applying the Intersection of Race and Gender
Authors: Suntai Zainab , Noh Hyunjin , Lee Lewis , Bell John Gregory , Lippe Megan P , Lee Hee Yun 
Published: February 2023

Abstract

Background and Objectives
Research on racial and gender disparities in end-of-life care quality has burgeoned over the past few decades, but few studies have incorporated the theory of intersectionality, which posits that membership in 2 or more vulnerable groups may result in increased hardships across the life span. As such, this study aimed to examine the intersectional effect of race and gender on the quality of care received at the end of life among older adults.

Research Design and Methods
Data were derived from the combined Round 3 to Round 10 of the National Health and Aging Trends Study. For multivariate analyses, 2 logistic regression models were run; Model 1 included the main effects of race and gender and Model 2 included an interaction term for race and gender.

Results
Results revealed that White men were the most likely to have excellent or good care at the end of life, followed by White women, Black men, and Black women, who were the least likely to have excellent or good care at the end of life.

Discussion and Implications
These results point to a significant disadvantage for Black women, who had worse end-of-life care quality than their gender and racial peers. Practice interventions may include cultural humility training and a cultural match between patients and providers. From a policy standpoint, a universal health insurance plan would reduce the gap in end-of-life service access and quality for Black women, who are less likely to have supplemental health care coverage.
Aging Out-of-Place: Perceptions of Successful Aging Among Aging Burundian Refugees in the United States
Authors: Owino Jonix , Fuller Heather 
Published: February 2023

Abstract

Background and Objectives
Refugees flee their home countries due to life-threatening situations and are resettled in countries such as the United States. For older refugees, their cultural background and forced migration experience may affect how they perceive successful aging in their host countries. As such, it is important to understand how aging refugees perceive aging well to enhance their well-being in the host communities. Thus, the present study explores perceptions of successful aging among refugees in the United States.

Research Design and Methods
Twenty-one Burundian refugees, aged 50–67, were recruited from an upper Midwest community to participate in interviews on their perceptions of successful aging. The qualitative interviews were analyzed using thematic content analysis.

Results
Emergent themes showed that aging refugees’ perceptions of successful aging were in some ways consistent with perceptions among other nonrefugee aging populations, such as perceptions related to physical functioning and health. Yet, in many ways, refugees’ unique background and experiences seemed to lead to unique aging perceptions, such as perceiving an earlier onset of aging and expressing surprise and appreciation to experience old age.

Discussion and Implications
Study findings suggest important future directions and potential implications for refugee host regions and communities on how they can better support aging refugees as well as develop effective interventions to promote well-being.

Published: February 2023

AbstractOBJECTIVESPrimary spontaneous pneumothorax is a common disease, whose surgical treatment is still enigmatic in terms of timing and technique. Herein, we reported our experience with the parenchymal-sparing technique via cold coagulation (CC), in comparison to stapler apicectomy (SA).METHODSWe retrospectively collected data of all patients with apical blebs or &lt;2 cm bullae treated with minimally invasive surgery for recurrent or persistent spontaneous pneumothorax, from 2010 to 2020. Two different surgical techniques were used: SA and the parenchymal-sparing CC of the apex. Perioperative and long-term results were analysed and compared.RESULTSOut of 177 patients enrolled, 77 patients (CC group) underwent cold-coagulation of the apex while 100 patients (SA group) were treated with SA. Two groups were comparable in terms of age, surgical indication, intraoperative findings and affected side. CC group had a mean operative time of 43.2 min (standard deviation ± 19.5), shorter than SA group with 49.3 min (standard deviation ± 20.1, P-value: 0.050). Complication rate was significantly different between 2 groups, 5 (7%) and 16 (16%), for the CC and SA groups, respectively (P: 0.048), even if not in terms of prolonged postoperative air leak (P: 0.16). During the follow-up, 13 homolateral recurrences were reported: 2 (3%) in group CC and 11 (11%) in group SA; with a significant difference (P: 0.044). All reinterventions (postoperative prolonged air leak and recurrences) required an SA.CONCLUSIONSParenchymal-sparing technique through CC of apical blebs and bullae is an effective treatment for primary spontaneous pneumothorax and guarantees a good immediate lung sealing, despite stapling still represents the choice treatment in complex cases.
Measurement and correction of TEM image distortion using arbitrary samples
Authors: Tamaki Hirokazu , Saitoh Koh 
Published: February 2023

Abstract
We have developed a method to quantitatively measure image distortion, one of the five Seidel aberrations, in transmission electron microscopes without using a standard sample with a known structure. Displacements of small local segments in an image due to image distortion of the intermediate and projection lens system are first measured by comparing images taken before and after a given shift at the first image plane of the objective lens. Then, the sum of the second partial derivatives, or the Laplacian, of the displacement field is measured, and the radial and azimuthal distortion parameters are determined from the measured results. We confirmed using numerically distorted images that the proposed method can measure the image distortion within a relative error ratio of 0.04 for a wide range of distortion amount from 0.1% to 5.0%. The distortion measurement and correction were confirmed to work correctly by using the experimental images, and the iterative measurement and correction procedure could reduce the distortion to a level where the average image displacement was &lt; 0.05 pixels.
Pleading for international law: assessing the influence of party to proceedings on legal change in international courts
Authors: Hamilton Byrne William , Godzimirska Zuzanna 
Published: February 2023

Abstract
Scholars increasingly seek to understand the driving forces behind change in international law. However, these analyses often tend to provide external forms of analysis that presume change can be identified without engaging with the actors or looking at the law. This article takes the role of party pleadings in international dispute settlement as a means through which we can assess the influence of actors on law-making. Taking the development of the ‘control of the crime’ theory at the International Criminal Court as its object, the article scrutinizes legal change by dissecting the multifaceted role of pleadings. Adopting an interdisciplinary approach and conducting quantitative analysis of citation patterns, content analysis of case law, and interviews with practitioners, it offers a novel methodological take and empirical insights into our understanding of what makes up legal change in international law, and how we can identify its meaning through different access points.
