Characterization of leaf trichomes and their influence on surface wettability of Salsola ferganica, an annual halophyte in the desert
Authors: Liu Yanxia , Hanati Alayi , Lan Haiyan 
Published: April 2023

AbstractMany organisms use functional surfaces to collect water from the atmosphere. Salsola ferganica Drob. is one of the most abundant plants in desert regions and thrives in extreme environments with multiple but limited water resources, including dew and fog; however, its mechanisms of water harvesting remain unclear. We investigated trichome structural characteristics and their influence on the surface wettability of S. ferganica leaves using a variety of approaches (scanning electron microscopy, optical microscopy, immunolabelling staining, x‐ray diffractometry, and infrared spectroscopy). Microstructural observations revealed that the trichomes of S. ferganica presented a curved upper part, the ‘spindle node’‐like structure in the middle, and the micro‐grooves structure in between; such unique structures may aid in capturing moisture from the air. The physicochemical characteristics of the trichome surface, including hydrophobic functional groups, hydrophilic pectins, and low crystallinity, may enhance the adhesion of water drops to trichomes. Furthermore, we discovered that the piliferous S. ferganica leaves were more effective in retaining water than the glabrous S. aralocaspica leaves, and the dense trichome layer exhibited a significantly unwettable surface (high contact angle with droplets), whereas the individual trichomes retained water effectively (more so under drought conditions). The combination of these two properties is consistent with the ‘rose petal effect’, which describes rough surfaces that are hydrophobic but exhibit high adhesion with water. These factors suggest that the evolutionary optimisation of water acquisition by coupling relevant microstructures with the physicochemical properties of trichomes enables S. ferganica to survive harsh conditions in the seedling stage.

Published: April 2023

AbstractTranspiration per unit of leaf area is the end‐product of the root‐to‐leaf water transport within the plant, and it is regulated by a series of morpho‐physiological resistances and hierarchical signals. The rate of water transpired sustains a series of processes such as nutrient absorption and leaf evaporative cooling, with stomata being the end‐valves that maintain the optimal water loss under specific degrees of evaporative demand and soil moisture conditions. Previous work provided evidence of a partial modulation of water flux following nitrogen availability linking high nitrate availability with tight stomatal control of transpiration in several species. In this work, we tested the hypothesis that stomatal control of transpiration, among others signals, is partially modulated by soil nitrate () availability in grapevine, with reduced availability (alkaline soil pH, reduced fertilization, and distancing source) associated with decreased water‐use efficiency and higher transpiration. We observed a general trend when was limiting with plants increasing either stomatal conductance or root‐shoot ratio in four independent experiments with strong associations between leaf water status, stomatal behavior, root aquaporins expression, and xylem sap pH. Carbon and oxygen isotopic signatures confirm the proximal measurements, suggesting the robustness of the signal that persists over weeks and under different gradients of availability and leaf nitrogen content. Nighttime stomatal conductance was unaffected by manipulation treatments, while application of high vapor pressure deficit conditions nullifies the differences between treatments. Genotypic variation for transpiration increase under limited availability was observed between rootstocks indicating that breeding (e.g., for high soil pH tolerance) unintentionally selected for enhanced mass flow nutrient acquisition under restrictive or nutrient‐buffered conditions. We provide evidence of a series of specific traits modulated by availability and suggest that fertilization is a potential candidate for optimizing grapevine water‐use efficiency and root exploration under the climate‐change scenario.
Charles Goodsell: A weaver of the tapestry of public administration
Authors: Barth Thomas J. 
Published: April 2023

AbstractOur society has the habit of writing about exemplars after they are no longer with us; this is certainly important and beneficial but misses the opportunity to engage them in a personal reflection on their lives and the contributions/lessons they most want to share. This essay is intended to address this common oversight by sharing the marvelous 61‐year career of Charles Goodsell, by first recounting his still active professional journey and closing with his own personal advice to academics, practitioners, and students.
Total reward preferences in the recruitment and retention of county chief administrative officers: Applying a push/pull theory of motivation
Authors: Lasseter Dan , Daman Alex 
Published: April 2023

AbstractMonetary rewards have historically played a prominent role in public employee turnover. Additionally, non‐monetary rewards such as internal environmental factors contribute to the ability to recruit, retain, and satisfy public employees. Our research seeks to apply the push and pull theory of motivation to the total reward (intrinsic and extrinsic rewards) preferences of county chief administrative officers (CAOs) in the state of Georgia. CAOs typically have job titles such as County Administrator or County Manager. In understanding which rewards are most valued by CAOs, local governments can better understand the ways their CAOs value different rewards. In other words, which rewards are most likely to “pull” a CAO to another position; and conversely, does the lack of certain rewards “push” CAOs towards other jurisdictions or even other careers? In addition, this research aims to examine whether demographic variables of CAOs impacts total reward preferences.
A cognitive network perspective for public administration and policy
Authors: Ertan Güneş , Siciliano Michael D. 
Published: April 2023

AbstractThis article introduces the concept of cognitive social structures to public administration and policy scholars. Cognitive social structures are the perceptions, or mental maps, actors hold of the relationships that exist among the members of their network. These perceptions and their accuracy have implications for actor behavior, decisions, and outcomes. The literature on network cognitions has developed in the fields of psychology and organization studies but has yet to be applied in public administration and policy. We provide an overview of cognitive social structure research. We then demonstrate the theoretical and practical implications cognitive social structures hold for our field by examining applications in two research areas—implementation and leadership. We argue that using a network cognition perspective can help researchers and practitioners to better explain and pursue important organizational and interorganizational phenomena. We hope this article fosters new dialogue on the role of network cognitions in public administration and policy.
Growing superdiverse, growing apart—Modes of incorporation of international migrants in rural areas
Authors: Stachowski Jakub , Rasmussen Bente 
Published: April 2023

AbstractThis article analyses the perceived impact of international migration on host rural communities from the perspectives of local stakeholders. Based on in‐depth interviews conducted in two rural locales in Norway, we identify a consensus about the indispensability of international labour migrants for the demographic and economic sustenance of the host rural communities. At the same time, the perspectives of stakeholders convey a complex picture of labour migration. The perceived impact of international migration is related to the tempo of migration and to the prior local history of migration that affects how it is represented and handled locally. Depending on the context, international migration may be treated as a common‐place phenomenon or as a force that profoundly affects the conception of the local community. Our findings illustrate a socio‐spatial variation of responses to international migration locally and suggest the emergence of new local social divisions along the growing superdiversity of rural communities.

Published: April 2023

AbstractBackgroundPhacomatosis pigmentokeratotica (PPK) is a distinct and rare type of epidermal nevus syndrome characterized by coexisting nonepidermolytic organoid sebaceous nevus (SN) with one or more speckled lentiginous nevi (SLN). Atypical nevi including compound Spitz and compound dysplastic may manifest within regions of SLN. Patients with PPK, or similar atypical nevus syndromes, may be subject to a significant lifetime number of biopsies, leading to pain, scarring, anxiety, financial burden, and decreased quality of life. The current literature includes case reports, genetics, and associated extracutaneous symptoms of PPK, but use of noninvasive imaging techniques have not been explored. We aim to investigate the value of high‐frequency ultrasound (HFUS) and optical coherence tomography (OCT) in discriminating morphological features of pigmented lesions and nevus sebaceous within one patient with PPK.Materials and methodsTwo modalities, (1) HFUS imaging, based on acoustic properties and (2) OCT imaging, based on optical properties, were used to image a patient with PPK. Benign pigmented lesions, which may raise clinical suspicion for significant atypia, and nevus sebaceous, were selected on different areas of the body to be studied.ResultsFive pigmented lesions and one area of nevus sebaceous were imaged and analyzed for noninvasive features. Distinct patterns of hypoechoic features were seen on HFUS and OCT.ConclusionHFUS provides a deep view of the tissue, with ability to differentiate gross structures beneath the skin. OCT provides a smaller penetration depth and a higher resolution. We have described noninvasive features of atypical nevi and nevus sebaceous on HFUS and OCT, which indicate benign etiology.
Impact of International Investment Agreements on Japanese FDI: A firm‐level analysis†
Authors: Urata Shujiro , Baek Youngmin 
Published: April 2023

AbstractIn this study, we examine the impact of Japan's International Investment Agreements (IIAs) on the locational choice of Japanese firms' foreign direct investment (FDI) by considering the quality of IIAs. We estimate the conditional logit model covering 12,435 FDI cases by 3838 Japanese companies in 92 host countries, 16 manufacturing sectors and 12 non‐manufacturing sectors from 2000 to 2019. We found that the presence of IIAs, particularly comprehensive and high‐level ones, has a positive impact on Japan's FDI. On the contrary, the past incidence of investor–state disputes has a negative impact. These effects are found to be particularly strong for FDI by small‐ and medium‐sized enterprises. High regulatory quality is found to attract FDI, whereas the positive impact of IIAs in attracting FDI is strong in a country with a low regulatory quality.
Intraocular neuroectodermal embryonal tumor in two rabbits
Authors: Co Carmon , Brakel Kelsey , Pinard Chantale L. , Foster Robert A. 
Published: April 2023

AbstractSpontaneous intraocular tumors are rarely reported in rabbits, despite their widespread use as laboratory animals. We describe two cases of intraocular neuroectodermal embryonal tumors, formerly primitive neuroectodermal tumors, in young rabbits. Histologically, both tumors exhibited prominent rosette or pseudorosettes, consistent with the histomorphology seen in human tumors. The neuroectodermal subtype is supported by immunoreactivity for the neuronal markers, SRY‐box transcription factor 2, microtubule‐associated protein 2, neuronal nuclear protein, and neuron‐specific enolase. In one of the rabbits, there was metastasis to the contralateral conjunctiva. Intraocular neoplasms can occur in young rabbits and eyes with refractory disease should be enucleated for clinical management.

Published: April 2023

AbstractAvian chlamydiosis is an acute or chronic bacterial disease of birds. Chlamydia psittaci is the primary agent of the disease. It is also an important zoonotic pathogen. Chlamydia avium and Chlamydia gallinacea have also been recognized as potential causative agents of the disease. Clinical signs of this disease can vary in severity. Asymptomatic infections of Chlamydia have commonly been reported in various birds worldwide. In this study, we investigated the distribution of Chlamydia species in healthy psittacine birds in Korea. A total of 263 samples (pharyngeal/cloacal swabs and faeces) were collected from psittacine birds of 26 species in five zoos, five parrot farms and seven parrot cafes between 2020 and 2021. Ages of these birds had a wide range (1 month to 30 years). During sample collection, no bird showed any clinical signs indicating diseases such as chlamydiosis. Samples were tested for the presence of Chlamydia spp. using real‐time PCR assays. Chlamydia spp. were detected in 168 (63.9%) samples and C. psittaci was detected in 96 (36.5%) samples. However, C. avium and C. gallinacea were not detected. There were no significant differences in the prevalence of asymptomatic infections in birds among three types of housing environments. Regarding ompA genotypes, 87 C. psittaci‐positive samples had genotype A based on sequence analysis (n = 28) and genotype‐specific real‐time PCR (n = 59). Other positive samples were untyped (n = 9). Overall findings showed high prevalence of asymptomatic infections of C. psittaci in psittacine birds in Korea, posing a significant hazard to public health.
Chemosensory cells in the respiratory tract as crucial regulators of innate immune responses
Authors: Hollenhorst Monika I. , Krasteva‐Christ Gabriela 
Published: April 2023

AbstractDuring recent years chemosensory cells in extraoral tissues have been established as mediators for the detection and regulation of innate immune processes in response to pathogens. Under physiological conditions, chemosensory cells are present throughout the respiratory epithelium of the upper and lower airways as well as in the main olfactory epithelium. Additionally, they emerge in the alveolar region of the lung upon viral infections. Chemosensory cells in the upper and the lower airways detect signalling molecules from gram‐positive and gram‐negative bacteria as well as aeroallergens and fungi. Upon stimulation they release multiple molecules, such as the transmitter acetylcholine, the cysteinyl leukotriene E4 and the cytokine interleukin‐25, which act as autocrine and paracrine signals and thereby orchestrate the innate immune responses in the respiratory system. Activation of chemosensory cells stimulates various immune cells, e.g. type 2 innate lymphoid cells, modulates mucociliary clearance and induces a protective neurogenic inflammation. This review compiles and discusses recent findings regarding chemosensory cell function in the respiratory tract.

<div>AbstractBackground:<p>Previous studies indicated that glucosamine supplements may have a general anticancer effect. This study aimed to assess whether the potential effect differs across different types of cancers in a large prospective cohort study.</p>Methods:<p>All participants from the UK Biobank who were free of cancers and had complete information on glucosamine use at baseline were included and followed up from 2006 until 2021. Cox proportional hazards models were used to assess the associations between regular glucosamine use and different site-specific cancers. Subgroup analyses were performed to explore potential interactions. Several sensitivity analyses were conducted to assess the robustness of the main findings.</p>Results:<p>A total of 450,207 eligible participants (mean age: 56.2 years; females: 53.3%) were included, of whom 84,895 (18.9%) reported regular glucosamine use at baseline. During a median of 12.5 years follow-up, glucosamine use was significantly associated with an increased risk of overall cancer [HR, 1.04; 95% confidence interval (CI), 1.01–1.06], skin cancer (HR, 1.11; 95% CI, 1.07–1.15), and prostate cancer (HR, 1.07; 95% CI, 1.01–1.13), and with a reduced risk of lung cancer (HR, 0.88; 95% CI, 0.79–0.97) after adjusting for potential confounders. Statistical interaction was observed for gender, age, and education for the association of glucosamine use with overall cancer risk (all <i>P</i><sub>interaction</sub> < 0.027). These results remained unchanged in the sensitivity analyses.</p>Conclusions:<p>Regular glucosamine use was associated with lower risk of lung cancer but higher risk of skin cancer, prostate cancer, and overall cancer.</p>Impact:<p>The roles of glucosamine use potentially differ in the development of different site-specific cancers.</p></div>

Authors: Chavan Arunkumar Pundalik , Aradhya Ravish 
Published: April 2023

<p><span lang="EN-US">The objective of the proposed work is to demonstrate the use of a hybrid approach for the design of a voltage-controlled oscillator (VCO) which can lead to higher performance. The performance is improved in terms of the tuning range, frequency of oscillation, voltage swing, and power consumption. The proposed hybrid VCO is designed using an active load common source amplifier and current starved inverter that are cascaded alternatively to achieve low power consumption. The proposed VCO achieves a measured phase noise of -74 dBc/Hz and a figure of merit (FOM) of -152.6 dBc/Hz at a 1 MHz offset when running at 5.1 GHz frequency. The hybrid current starved-current starved VCO (CS-CS VCO) consumes a power of 289 µW using a 1.8 V supply and attains a wide tuning range of 96.98%. Hybrid VCO is designed using 0.09 µm complementary metal–oxide–semiconductor (CMOS) technology. To justify the robustness, reliability, and scalability of the circuit different corner analysis is performed through 500 runs of Monte-Carlo simulation.</span></p>
Customer sentiment analysis for Arabic social media using a novel ensemble machine learning approach
Authors: Hicham Nouri , Karim Sabri , Habbat Nassera 
Published: April 2023

<span lang="EN-US">Arabic’s complex morphology, orthography, and dialects make sentiment analysis difficult. This activity makes it harder to extract text attributes from short conversations to evaluate tone. Analyzing and judging a person’s emotional state is complex. Due to these issues, interpreting sentiments accurately and identifying polarity may take much work. Sentiment analysis extracts subjective information from text. This research evaluates machine learning (ML) techniques for understanding Arabic emotions. Sentiment analysis (SA) uses a support vector machine (SVM), Adaboost classifier (AC), maximum entropy (ME), k-nearest neighbors (KNN), decision tree (DT), random forest (RF), logistic regression (LR), and naive Bayes (NB). A model for the ensemble-based sentiment was developed. Ensemble classifiers (ECs) with 10-fold cross-validation out-performed other machine learning classifiers in accuracy (A), specificity (S), precision (P), F1 score (FS), and sensitivity (S).</span><p> </p>

Published: April 2023

Abscesso hepático é o tipo mais comum de abscesso visceral. Sua prevalência é estimada em 2,3 casos por 100.000 pessoas anualmente e é maior entre homens do que mulheres. O abscesso hepático pode vir acompanhado por sinais e sintomas comuns a outras doenças como febre, emagrecimento e dor no hipocôndrio direito. Dessa forma, o diagnóstico essencialmente clínico é difícil de ser estabelecido. O artigo objetiva discutir o abscesso hepático em paciente com febre de origem indeterminada (FOI), através do relato de caso de um paciente de 43 anos que, dentre outros sintomas, apresentava tosse. O quadro clínico associado a aspectos epidemiológicos, levantaram a suspeita inicial de afecções respiratórias, o que postergou o diagnóstico de abscesso hepático.

Published: April 2023

Fibromialgia caracteriza-se pela ocorrência de dor generalizada referida na musculatura na ausência de anormalidades evidenciadas aos exames complementares. Ocorrência mais freqüentemente no sexo feminino e nos indivíduos adultos. Pode associarse à fadiga, cefaléia, síndrome do cólon irritável, síndrome da cistite intersticial entre outras condições. Pontos dolorosos sãoamplamente distribuídos e identificáveis na musculatura. Ansiedade e depressão são comuns nestes casos. Sua fisiopatologia é incerta, admite-se que seja devida a hipotividade serotoninérgica e à hiperatividade p-érgica. Doentes com fibromialgia secundária podem apresentar anormalidades tireoidianas, diabete, etc. O tratamento consiste do emprego de antidepressivos tricíclicos,miorrelaxantes de ação central, analgésicos antiinflamatórios e neurolépticos. O implante de sistemas para infusão crônica de medicamentos analgésicos no compartimento liquórico é opção em casos rebeldes ao tratamento conservador.

Published: April 2023

Abstract
This paper provides a reflection on a practice-based computational art project titled Programmoire that explores the presence of computation within the medieval Arabic tradition of magic squares in both its mathematical origins and its magical mutation. The research speculates on an alternative history for technology rooted in the history of magic. Through examining the shared use of symbolic logic and active syntax between coding languages and symbolic magic, the project asks what technology can look like if used as a magical tool and how artistic practice can guide this exploration.
