Nurse experiences of partnership nursing when caring for children with long‐term conditions and their families: A qualitative systematic review
Authors: Barratt Macey , Bail Kasia , Lewis Peter , Paterson Catherine
Published: November 2023

Aim

To explore the experiences of partnership nursing among nurses when caring for children and young people with long‐term conditions, and their families.

Background

Partnership nursing is promoted as a positive model of care among paediatric nurses, where shared roles and decision‐making, parental participation, mutual trust and respect, communication and negotiation are valued to create positive care experiences and enhance patient outcomes. Little is known about how nurses use partnership with both the patient and the parents in this triad to deliver partnership nursing.

Design

A qualitative systematic review followed Joanna Briggs Institute meta‐aggregation approach and has been reported according to PRISMA guidelines.

Methods

A comprehensive systematic search was conducted in seven electronic databases. Studies were assessed according to a pre‐determined inclusion criteria. Qualitative findings with illustrative participant quotes were extracted from included studies and grouped into categories to inform overall synthesised findings. Methodological quality assessment was conducted.

Findings

A total of 5837 publications were screened, and 41 qualitative studies were included. Three overarching synthesised findings were identified: (1) Using education to promote feelings of safety and support, (2) Partnering to develop a strong therapeutic relationship and (3) Optimising communication underpinned by shared decision‐making principles to deliver individualised care.

Conclusion

Nurses demonstrated successful partnership in their practice, but focused on developing dyadic nurse–parent and dyadic nurse–child partnerships. Future practice development that creates a three‐way triadic partnership may aid therapeutic relationships and shared decision‐making.

Implications for clinical practice

Clinicians can reflect on how dyadic partnerships (focusing on the child or the parent) may exclude opportunities for coherent care. Further exploration in practice, policy and research as to how nurses determine child competency and child and parent level of engagement in triadic partnership may improve the potential of meaningful shared decision‐making.

Published: November 2023

Background

Splenectomy is commonly used to treat refractory immune–mediated cytopenia, but there are no established factors that are associated with response to the procedure.

Objectives

A cohort study was conducted to evaluate the hematologic and surgical outcomes of splenectomy in adult patients with immune cytopenias and identify preoperative factors associated with response.

Methods

Data from the Cleveland Clinic Foundation for 1824 patients aged over 18 who underwent splenectomy from 2002 to 2020 were analyzed.

Results

The study found that the most common indications for splenectomy were immune thrombocytopenic purpura (ITP) and autoimmune hemolytic anemia, with a median age of 55 years and median time from diagnosis to splenectomy of 11 months. Hematologic response rates were 74% overall, with relapse in 12% of cases. Postsplenectomy discordant diagnoses were present in 13% of patients, associated with higher relapse rates. Surgery‐related complications occurred in 12% of cases, whereas only 3% of patients died from disease complications. On univariate analysis, preoperative factors associated with splenectomy treatment failure were ≥3 lines of pharmacologic treatment, whereas isolated thrombocytopenia, primary ITP, and age ≤40 years had a strong association with response. The multivariable regression confirmed that treatment failure with multiple lines of medical therapy was associated with the failure to respond to splenectomy.

Conclusion

Overall, the study demonstrates that splenectomy is an effective treatment option for immune‐mediated cytopenias with a low complication rate.
Team conflict at the core: Exploring the influence of critical team member conflict on team creative functioning
Authors: Liao Huiyao , Harris T. Brad , Li Ning , Han Yuqing
Published: November 2023

Scholars have long been intrigued by the relationship between intrateam conflict and team creativity, though findings to date have been mixed. Recent research suggests that traditional conceptualizations of intrateam conflict as a property that is shared uniformly by team members (e.g., averaging members' overall conflict perceptions), rather than a more nuanced phenomenon between individual members with unique network positions, have limited our understanding of its influences. These advances, however, have yet to be substantively applied to the intrateam conflict‐creativity literature. Accordingly, we integrate network views of conflict with creativity theory and group motivated processing models to explore how task and relationship conflicts involving critical members' (i.e., members central to a team's workflow network) influence team creative functioning beyond overall conflict perceptions. We theorize that critical member task conflict is positively associated with team creativity by way of team reflexivity, and this positive indirect effect is accentuated by team shared goals. Further, we posit that critical member relationship conflict is negatively associated with team creativity by way of reduced team cohesion, though this effect is mitigated by critical member emotional intelligence. Analyses of 70 new product development teams support most hypotheses while also highlighting interesting nuance and future research opportunities.

Published: November 2023

Background

Coffee is one of the most consumed beverages in the world. Containing an abundance of bioactive molecules including polyphenols and flavonoids, the constituents of this beverage may exert antiproliferative, antioxidant and anti‐inflammatory effects.

Methods

We conducted a systematic review to summarise the available evidence on the anticancer effects of coffee constituents and their potential therapeutic use for oral squamous cell carcinoma (OSCC). Studies were identified through a comprehensive search of OVID MEDLINE, OVID EMBASE and Web of Science, including articles from any year up to 15 May 2023.

Results

Of the 60 reviewed papers, 45 were in vitro, 1 was in silico and 8 were in vivo exclusively. The remaining studies combined elements of more than one study type. A total of 55 studies demonstrated anti‐proliferative effects, whilst 12 studies also investigated migration and invasion of neoplastic cells. The constituents studied most frequently were quercetin and epigallocatechin gallate (EGCG), demonstrating various cytotoxic effects whilst also influencing apoptotic mechanisms in cancer cell lines. Dose‐dependent responses were consistently found amongst the studied constituents.

Conclusion

Whilst there was heterogeneity of study models and methods, consistent use of specific models such as SCC25 for in vitro studies and golden hamsters for in vivo studies enabled relative comparability. The constituents of coffee have gained significant interest over the last 30 years, particularly in the last decade, and present an area of interest with significant public health implications. Currently, there is a paucity of literature on utilization of active coffee constituents for the therapeutic treatment of oral cancers.

Authors: Raabe Clemens , Abou‐Ayash Samir , Yilmaz Burak , Surbek Fiona Jennifer , Chappuis Vivianne , Couso‐Queiruga Emilio
Published: November 2023

Purpose

This in vitro study aimed to assess the positional accuracy during the sequence of static computer‐assisted implant surgery (sCAIS) according to the anatomical characteristics of the alveolar ridge.

Material and Methods

Maxillary bone models with six single tooth gaps including clinical scenarios of healed alveolar ridge (HR), single‐rooted (SRS), and three‐rooted socket (TRS) morphologies were used in this study. Positional deviations during implant placement procedures were evaluated after the pilot osteotomy (PD), final osteotomy (FD), and implant placement with respect to the pre‐planned implant position by using a software package. ANOVA and post hoc analyses were performed.

Results

A total of 90 implants were included in this study. Higher mean angular, crestal, and apical deviations were found after the PD and FD (3.5 ± 2.4°, 0.7 ± 0.3 mm, and 1.4 ± 0.8 mm versus 3.6 ±2.2°, 0.6 ± 0.3 mm, and 1.2 ± 0.6 mm) compared to IP (2.8 ± 1.6°, 0.7 ± 0.3 mm, and 1.2 ± 0.5 mm, p ≤ 0.004). Implants placed in TRS demonstrated higher mean angular, crestal, and apical deviations (4.0 ± 1.7°, 0.8 ± 0.3 mm, and 1.6 ± 0.5 mm) compared to implants placed in SRS (2.5 ± 1.2°, 0.7 ± 0.3 mm, and 1.1 ± 0.4 mm) or HR (2.0 ± 0.9°, 0.5 ± 0.3 mm, and 0.8 ± 0.4 mm, p < 0.001).

Conclusions

Positional deviations during sCAIS procedures are initiated with the first implant osteotomy and persist throughout the drilling sequence. However, deviations slightly decreased after implant placement. The alveolar ridge morphology is strongly associated with positional deviations. Higher deviations were observed in three‐rooted and single‐rooted sockets simulating an immediate approach compared to healed sites simulating a delayed protocol.
Putting the F into FBD analysis: tree constraints or morphological data?

Published: November 2023

The fossilized birth–death (FBD) process provides an ideal model for inferring phylogenies from both extant and fossil taxa. Using this approach, fossils are directly integrated into the tree, leading to a statistically coherent prior on divergence times. Since fossils are typically not associated with molecular sequences, additional information is required to place fossils in the tree. We use simulations to evaluate two different approaches to handling fossil placement in FBD analyses: using topological constraints, where the user specifies monophyletic clades based on established taxonomy, or using total‐evidence analyses, which use a morphological data matrix in addition to the molecular alignment. We also explore how rate variation in fossil recovery or diversification rates impacts these approaches. We find that the extant topology is well recovered under all methods of fossil placement. Divergence times are similarly well recovered across all methods, with the exception of constraints which contain errors. We see similar patterns in datasets which include rate variation, however, relative errors in extant divergence times increase when more variation is included in the dataset, for all approaches using topological constraints, and particularly for constraints with errors. Finally, we show that trees recovered under the FBD model are more accurate than those estimated using non‐time calibrated inference. Overall, we show that both fossil placement approaches are reliable even when including uncertainty. Our results underscore the importance of core taxonomic research, including morphological data collection and species descriptions, irrespective of the approach to handling phylogenetic uncertainty using the FBD process.

Wheat is one of the most important cereal crops in the world. Cold stress is a major constraint in production of wheat grown in cold climate regions. In this study, we conducted a comprehensive assessment of cold stress tolerance in wheat genotypes through field screening, cell membrane stability through electrolyte leakage assay and biochemical profiling. A core set comprising 4560 genotypes was evaluated for two years (2021–2022), revealing substantial genetic variation for cold stress tolerance. Most genotypes exhibited moderate tolerance, while a smaller proportion showed susceptibility to cold stress. Based on the cold screening data in the field, a mini‐core set of 350 genotypes was selected for membrane stability analysis using electrical conductivity assays. Significant differences were observed in membrane stability among the genotypes, indicating the presence of genetic variation for this trait. Furthermore, a mini‐core set was narrowed down to 50 diverse candidate genotypes that were subsequently profiled for various biochemicals, including reactive oxygen species (ROS) like lipid peroxidation (MDA) and hydrogen peroxide (H202), osmoprotectant (proline) and enzymatic antioxidants including ascorbate peroxidase (APX), superoxide dismutase (SOD), guaiacol peroxidase (GPX), and catalase (CAT). Correlation analysis of the biochemicals revealed negative associations between antioxidants and reactive oxygen species (ROS), highlighting their role in mitigating oxidative damage under cold stress. This study enhances our understanding of the physiological and biochemical mechanisms underlying cold stress tolerance in wheat. The identified genotypes with superior cold stress tolerance can serve as valuable genetic resources for wheat breeding.

Published: November 2023

Terrestrialization by photosynthetic eukaryotes took place in the two branches of green microalgae: Chlorophyta and Charophyta. Within the latter, the paraphyletic streptophytic algae divide into two clades. These are named Klebsormidiophyceae‐Chlorokybophyceae‐Mesostigmatophyceae (KCM), which is the oldest, and Zygnematophyceae‐Coleochaetophyceae‐Charophyceae (ZCC), which contains the closest relatives of vascular plants. Terrestrialization required the emergence of adaptations in response to new challenges, such as irradiance, temperature oscillations and water deprivation. In this study, we evaluated lipid composition in species representative of distinct phylogenetic clusters within Charophyta and Chlorophyta. We aim to study whether the inherent thylakoid lipid composition, as well as its adaptability in response to desiccation, were fundamental factors for the evolutionary history of terrestrial plants. The results showed that the lipid composition was similar to that found in flowering land plants, differing only in betaine lipids. Likewise, the largest constitutive pool of oligogalactolipids (OGL) was found only in the fully desiccation‐tolerant species Klebsormidium nitens. After desiccation, the content of polar lipids decreased in all species. Conversely, the content of OGL increased, particularly trigalactosyldiacylglycerol and tetragalactosyldiacylglycerol in the ZCC clade. The analysis of the molecular species composition of the newly formed OGL may suggest a different biosynthetic route for the KCM and ZCC clades. We speculate that the appearance of a new OGL synthesis pathway, which eventually arose during the streptophyte evolutionary process, endowed algae with a much more dynamic regulation of thylakoid composition in response to stress, which ultimately contributed to the colonization of terrestrial habitats.
Heterologous expression of PtAAS1 reveals the metabolic potential of the common plant metabolite phenylacetaldehyde for auxin synthesis in planta

Published: November 2023

Aromatic aldehydes and amines are common plant metabolites involved in several specialized metabolite biosynthesis pathways. Recently, we showed that the aromatic aldehyde synthase PtAAS1 and the aromatic amino acid decarboxylase PtAADC1 contribute to the herbivory‐induced formation of volatile 2‐phenylethanol and its glucoside 2‐phenylethyl‐β‐D‐glucopyranoside in Populus trichocarpa. To unravel alternative metabolic fates of phenylacetaldehyde and 2‐phenylethylamine beyond alcohol and alcohol glucoside formation, we heterologously expressed PtAAS1 and PtAADC1 in Nicotiana benthamiana and analyzed plant extracts using untargeted LC‐qTOF‐MS and targeted LC–MS/MS analysis. While the metabolomes of PtAADC1‐expressing plants did not significantly differ from those of control plants, expression of PtAAS1 resulted in the accumulation of phenylacetic acid (PAA) and PAA‐amino acid conjugates, identified as PAA‐aspartate and PAA‐glutamate. Herbivory‐damaged poplar leaves revealed significantly induced accumulation of PAA‐Asp, while levels of PAA remained unaltered upon herbivory. Transcriptome analysis showed that members of auxin‐amido synthetase GH3 genes involved in the conjugation of auxins with amino acids were significantly upregulated upon herbivory in P. trichocarpa leaves. Overall, our data indicates that phenylacetaldehyde generated by poplar PtAAS1 serves as a hub metabolite linking the biosynthesis of volatile, non‐volatile herbivory‐induced specialized metabolites, and phytohormones, suggesting that plant growth and defense can be balanced on a metabolic level.

Published: November 2023

Background

Current literature lacks evidence about the relationship between reminiscence functions and depression and the mediating role of clinical constructs such as loneliness and religion. The study aimed to examine the mediating effects of loneliness and religion on the association between reminiscence functions and depression in a sample of older Jordanian adults.

Methods

An anonymous online cross‐sectional survey was employed to collect data from 365 older Jordanian adults. Convenience and snowball sampling methods were used to recruit participants through social media.

Results

In the depression model, Bitterness Revival and Intimacy Maintenance factors, educational level, and Intrinsic Religiosity were statistically significant predictors of depression. Bitterness Revival and Intimacy Maintenance factors, work sector, and Intrinsic Religiosity were statistically significant predictors of loneliness. Loneliness has a negative, partial mediating effect on Intimacy Maintenance and depression.

Conclusion

Depression caused by significant losses in the Arab Jordanian environment might be mitigated by Intimacy Maintenance by reducing feelings of loneliness. Understanding how Intimacy Maintenance correlates with depression through loneliness could help psychiatric nurses develop psychosocial interventions that reduce depression among older adults.
Does participation predict support for place brands? An analysis of the relationship between stakeholder involvement and brand citizenship behavior
Authors: Ripoll González Laura , Klijn Erik Hans , Eshuis Jasper , Braun Erik
Published: November 2023

This article studies in how far participation of stakeholders enhances their active support for place brands, conceptualized in this study as Brand Citizenship Behavior (BCB). Combining insights from governance and branding theory this article uses survey data (N = 162) among stakeholders involved in branding processes of two Dutch regions. The analysis shows that more intense participation in the development of the brand is related to more BCB. Beyond participation, perceived value of the brand for stakeholders and degree of place identity (identification with place) also positively relate to brand citizenship behavior. The findings not only confirm the importance of participation in achieving support for public brands, but also provide insight into the role of affective factors (identification) and interest‐based factors (value of the brand for the stakeholder) on BCB.

Due to the high rate of post‐operative sepsis and other infectious complications, a routine immunological screening protocol has been initiated since 2015 in our paediatric surgery clinic for all patients admitted with oesophageal atresia (EA) and warrant a delayed definitive treatment. In our study, we aimed to evaluate the immunodeficiencies in EA patients, by comparing them to healthy age‐matched controls. As a prospective cohort study, EA patients admitted between 2015 and 2022, who had their definitive operation after the newborn period (>28 days of age) were included. On admission, serum concentrations of IgG, IgA, IgM, lymphocyte subset levels, C3 and C4 levels, specific IgG antibody responses against hepatitis B, hepatitis A, measles, varicella zoster were evaluated. The patients were age‐matched with healthy controls to compare the results and followed up until three years of age. If a humoral immunodeficiency was detected, intravenous immunoglobulin treatment was administered before major oesophageal surgery and during follow‐up. 31 EA patients (18 M/13F) with a mean age of 13.3 ± 9.0 months were compared with 40 age‐matched healthy controls. Mean serum IgG levels were found to be statistically lower than controls in all age groups (P < .05). Transient hypogammaglobulinemia of infancy (THI) and unclassified syndromic immunodeficiencies (USI) were found to be strikingly high, accounting for 29.0% and 22.5%, respectively, adding up to 51.5% of EA patients. This is the first study evaluating immunodeficiencies in EA patients found in the reviewed literature. More than half of EA patients that required delayed surgery had humoral immunodeficiency, so preoperative screening and immunology referral may improve patient outcomes.

Objective

Chagas cardiomyopathy (ChC) is the most severe clinical form of Chagas disease and, in association with psychosocial factors, can compromise the health‐related quality of life (HRQoL) of affected patients. To date, there is no specific instrument to assess the HRQoL of these patients, and the Minnesota Living with Heart Failure Questionnaire (MLwHFQ), specific for heart failure, is being used both in research and current clinical practice. Therefore, we aimed to verify the validity of the MLwHFQ in the assessment of HRQoL of patients with ChC.

Methods

Fifty patients with ChC (50.6 ± 10.1 years, NYHA I‐III) were evaluated. The MLwHFQ, Short‐Form of Health Survey (SF‐36), Beck Depression Inventory (BDI), and Human Activity Profile (HAP) were applied. All patients underwent echocardiography and Cardiopulmonary Exercise Testing (CPET).

Results

The MLwHFQ score correlated with almost all SF‐36 domains (with r‐value ranging from −0.38 to −0.69), except pain (p = 0.118). The MLwHFQ score also correlated with the BDI score (r = 0.748; p < 0.001), HAP score (r = −0.558; p = 0.001), peak oxygen uptake (r = −0.352; p = 0.01), and left ventricular ejection fraction (r = −0.329; p = 0.021). There was no significant difference in the score found on the MLwHFQ among NYHA classes (p = 0.101), as well as between patients with systolic dysfunction (n = 30) and preserved cardiac function (n = 20) (p = 0.058). Similarly, there was no significant difference in the score found on the physical (p = 0.423) and mental (p = 0.858) components of SF‐36 between patients with systolic dysfunction and preserved cardiac function (p = 0.271 and p = 0.609, respectively). There was also no difference in the mental component of SF‐36 among NYHA classes (p = 0.673). However, the HRQoL using the physical component of SF‐36 was worse in advanced NYHA classes (p = 0.014).

Conclusion

MLwHF correlated with most SF‐36 HRQoL domains, depressive symptoms, physical activity, and systolic function and seems to be valid in assessing the HRQoL of ChC patients.
A DELAY OF GERMINATION 1 (DOG1)‐like protein regulates spore germination in the moss Physcomitrium patens

DELAY OF GERMINATION 1 is a key regulator of dormancy in flowering plants before seed germination. Bryophytes develop haploid spores with an analogous function to seeds. Here, we investigate whether DOG1 function during germination is conserved between bryophytes and flowering plants and analyse the underlying mechanism of DOG1 action in the moss Physcomitrium patens. Phylogenetic and in silico expression analyses were performed to identify and characterise DOG1 domain‐containing genes in P. patens. Germination assays were performed to characterise a Ppdog1‐like1 mutant, and replacement with AtDOG1 was carried out. Yeast two‐hybrid assays were used to test the interaction of the PpDOG1‐like protein with DELLA proteins from P. patens and A. thaliana. P. patens possesses nine DOG1 domain‐containing genes. The DOG1‐like protein PpDOG1‐L1 (Pp3c3_9650) interacts with PpDELLAa and PpDELLAb and the A. thaliana DELLA protein AtRGA in yeast. Protein truncations revealed the DOG1 domain as necessary and sufficient for interaction with PpDELLA proteins. Spores of Ppdog1‐l1 mutant germinate faster than wild type, but replacement with AtDOG1 reverses this effect. Our data demonstrate a role for the PpDOG1‐LIKE1 protein in moss spore germination, possibly alongside PpDELLAs. This suggests a conserved DOG1 domain function in germination, albeit with differential adaptation of regulatory networks in seed and spore germination.

Published: November 2023

The current study aimed to evaluate the dispersal of solution and microbes (aerosol) in the clinical environment during treatment with Low‐frequency contact ultrasonic debridement (LFCUD) with or without suction attachment in patients with diabetic foot ulcers (DFUs). We performed 20 treatments in 10 patients divided into two groups to receive the proposed LFCUD modalities. We measured the microbial load of the environment pre‐treatment (sample M1), during treatment with each LFCUD modality (sample M2) and post‐treatment (sample M3). The use of LFCUD debridement without a suction attachment results in significantly higher immediate contamination of the clinic environment than the suction attachment, particularly during the procedure (1.70 ± 0.98 log 10 CFU/mL versus 0.77 ± 0.85 log 10 CFU/mL, p = 0.035). When suction is not applied, there are statistically significant differences depending on whether the DFUs are neuropathic or neuroischemic, finding a greater number of microorganisms with high loads in neuropathic DFUs. We found a statistically significant positive correlation between wound area (r = 0.450, p = 0.047) and TBI (r = 0.651, p = 0.006) with the bacterial load during the LFCUD. Based on our results, we recommend using the personal protective equipment required to protect staff members and patients during treatment with LFCUD and using a suction attachment where clinically possible to reduce clinic environmental pollution, especially in neuropathic DFUs and those with larger areas.
Primes with a missing digit: Distribution in arithmetic progressions and an application in sieve theory
Authors: Nath Kunjakanan
Published: November 2023

We prove Bombieri–Vinogradov type theorems for primes with a missing digit in their ‐adic expansion for some large positive integer . The proof is based on the circle method, which relies on the Fourier structure of the integers with a missing digit and the exponential sums over primes in arithmetic progressions. Combining our results with the semi‐linear sieve, we obtain an upper bound and a lower bound of the correct order of magnitude for the number of primes of the form with a missing digit in a large odd base .
Gente alzada en cámaras. Canibalismo cultural y subjetividad en el video indígena
Authors: Vallejo César Alegría
Published: November 2023

En el umbral del nuevo siglo, las naciones indígenas en Colombia pasaron de ser presentadas en el cine y el video a ser agentes de su representación: para esto, pueblos e individuos han delineado estrategias de apropiación y comunicación. Gente alzada en cámaras analiza cómo dos directores de origen indígena, Mileidy Orozco (embera eyábida) y Luis Tróchez (misak), “canibalizan” o se apropian de las cámaras de video en espacios institucionales occidentales —universidades, en este caso— para adquirir una forma de operar con ellas. El resultado de esta transacción entre lo propio y lo ajeno son películas documentales en primera persona del singular, obras que responden a las necesidades políticas y afectivas de los autores, quienes a través del acento autobiográfico reflexionan sobre el exilio, la migración, la desterritorialidad y el racismo en un espacio-tiempo globalizado. Así, este libro es una apuesta por comprender la experiencia individual indígena contemporánea en el mundo histórico a través del dispositivo audiovisual como medio para construir memoria, dialogar interculturalmente o movilizar a las comunidades en procesos de resistencia, entre otros.
El espacio público y la ciudad filosófica como retóricas contra el conflicto. Apuntes sobre los casos de Barcelona y Medellín
Authors:   Universidad de Barcelona, Delgado Ruiz Manuel
Published: November 2023

El concepto de espacio público, tomado de la filosofía política, sirve desde hace relativamente poco –final de los años 1980– para nombrar lo que antes se había designado como lugar público o sencillamente calle. Cargado de connotaciones ideológicas, espacio público es una de las categorías-fetiche en que se basan los discursos arquitectónicos, urbanísticos y de gobernabilidad y es clave en la actual revalorización al mismo tiempo mercantil y moral de los huecos urbanos, en el marco de las grandes dinámicas de apropiación capitalista de las ciudades.
Dynamics of plasma atomic layer etching: Molecular dynamics simulations and optical emission spectroscopy
Authors: Vella Joseph R. , Hao Qinzhen , Donnelly Vincent M. , Graves David B.
Published: November 2023

Atomic layer etching is intrinsically dynamic as it involves sequential and repeated exposures of a surface to be etched with different species at different energies. The composition and structure of the near surface region change in both time and depth. Full understanding of this process requires resolving both temporal and spatial variations. In this work, we consider silicon (Si) atomic layer etching (ALE) by alternating exposure to chlorine gas (Cl2) and argon ions (Ar+). Molecular dynamics (MD) simulations are compared to experimental measurements with the aim of better understanding the dynamics of ALE and to test the simulation procedure. The simulations help to more fully interpret the experimental measurements. Optical emission measured just above the surface being etched can be related to etch products and can, therefore, be directly compared to simulation predictions. The simulations capture the measured initial product distribution leaving the surface and match the measured etch per cycle reasonably well. While simulations demonstrate the importance of ion-induced surface damage and mixing into a layer below the surface, the depth of which depends mainly on ion energy, the experiments suggest there is more Cl mixed into the layer than the MD procedure predicts.

Function-Level Code Obfuscation Detection Through Self-Attention-Guided Multi-Representation Fusion
Authors: Tian Zhenzhou , He Ruikang , Zhao Hongliang , Chen Lingwei
Published: November 2023

Malware developers often employ code obfuscation techniques to conceal their malicious functionality, making it challenging to detect and analyze such software. While various de-obfuscation techniques exist, the majority of them require prior knowledge of the obfuscation tools and techniques in use. Identifying the specific obfuscation tools or algorithms applied to the obfuscated code is thus of vital importance, which, however, typically demands in-depth expert knowledge and substantial efforts. Therefore, this paper presents DeObA, a deep learning (DL) driven approach for the precise and efficient detection of obfuscation algorithms on the fine-grained function-level code snippets. To comprehensively capture unique patterns or features of different obfuscation algorithms from code, DeObA works on multiple distinct code views, encompassing token sequences, abstract syntax trees (AST) and program dependency graphs (PDG), which will reflect the code’s lexical morphology, syntactic and structural aspects. After individually collecting obfuscation-indicative features with well-matched DL encoder from each code view, a self-attention-based fusion strategy is performed on these features to produce an integrated, dense, yet feature-rich vector. This vector is then fed into a softmax classification layer for prediction. Due to the lack of a moderately sized dataset, a large obfuscation corpus is curated with 7 different obfuscation tools and a total of 12 obfuscation algorithms on 39,070 C/C[Formula: see text] functions. The experimental evaluations conducted on the dataset exhibit a distinguished detection performance of DeObA, which achieve accuracy rates of 99.90% and 99.19% on the obfuscation tool detection and obfuscation algorithm detection tasks, respectively. The ablation study also confirms the active role of considering multiple distinct code views and the effectiveness of the designed self-attention-based fusion strategy.
PDEs FOR REFLECTED BSDENMs APPLIED TO AMERICAN OPTIONS
Authors: EL JAMALI MOHAMED , TAYEQ HATIM
Published: November 2023

This paper studies the solution of a backward stochastic differential equation driven by normal martingale (BSDENM for short) with a right continuous and left limited lower obstacle (rcll for short) assuming a nondeterministic Lipschitz condition. We prove the existence and uniqueness of the solution via penalization methods with the help of the monotonic limit theorem and the Snell envelope theory. As for application, we discuss the fair valuation of American options and the connection between reflected BSDENM and partial differential equations (PDEs for short).

Published: November 2023

Stationary geodesic networks are the analogs of closed geodesics whose domain is a graph instead of a circle. We prove that for a Baire-generic Riemannian metric on a smooth manifold [Formula: see text], all connected embedded stationary geodesic nets are nondegenerate.

Here, we report investigations on the relative humidity (RH) sensing property of ZnO nanotubes synthesized via hydrothermal method. Grown nanotubes are formed with a hexagonal shape and possess a wurtzite crystal structure in conjunction with higher oxygen vacancies. ZnO nanotube-based RH sensor shows a small current increase in lower RH (<75% RH) region, due to the frozen motion of H[Formula: see text] ions, where electronic conduction dominates. The sensor conduction increases from 13 to 960 fold upon exposer of 65%–90% RH, respectively. The free motion of H[Formula: see text] ions steers the conduction mechanism to be protonic in higher level physisorbed water layer and is responsible for the observed sharp increase in response. The competitive adsorption and desorption of oxygen species and water molecules play a vital role in defining the conduction to be electronic or protonic during the experiment.

A ferrimagnetic hexagonal Ising nanotube with spin-1/2 core and spin-5/2 shell is investigated using the mean field approximation (MFA) and the Monte Carlo simulation (MCS). More exactly, we have examined the effects of the exchange interactions and crystal field on the magnetic properties of the system. Our phase diagrams show the appearance of critical and compensation behaviors, as well as first-order phase transitions terminating at isolated critical end-points in the ferrimagnetic phase region at low temperatures. Furthermore, we have made a comparison with other studies of similar nanosystems.
Active Disturbance Rejection Predictive Control for Local Trajectory Planning of Unmanned Ground Vehicles
Authors: Xia Lingxiang , Su Jianbo
Published: November 2023

In this paper, an active disturbance rejection predictive control strategy is proposed for trajectory planning task of unmanned ground vehicles. Rather than error estimation of accurate system modeling, internal error and environment disturbance are processed via single extended state observer. Nonlinear feedback control law is applied to reduce steady-state error significantly. Then motion planning and nonholonomic constraints could be handled via nonlinear model predictive control. Simulation and experiment results show that the proposed algorithm is able to accomplish trajectory planning task with internal error and environment disturbance.
Soft Power in India-South Korea Relations and Role of Cultural and Popular Connections
Authors: MISHRA SANDIP KUMAR
Published: November 2023

India and South Korea relationship has seen remarkable journey in the last three decades. Apart from rising political and economic weights of both the countries, India and South Korea have also emerged as important soft powers in the region. Their soft powers are based on their rich cultural and historical heritages, their democratic traditions and productions of world famous entertainment contents such as movies, dramas, music and so on. The awareness of the cultural connection between the two countries might have been less than expected but both the countries are indeed committed to reach out each other through these connections. Actually soft powers of both the countries are also useful in connecting them bilaterally as well as providing them access to the Southeast Asian countries. This paper tries to look at the role of soft powers of both the countries in their bilateral relations. When the small and middle powers of the region are forced by the US-China contests to work more on their hard powers and alliances/partnerships, the paper argues that a cooperative narrative may emerge in the region through the soft powers reach outs of India and South Korea and their attempts of agenda setting for the region. The paper would also try to explore trajectory of India-South Korea people-to-people connections and flag problems and prospects in the process.

Android operating systems have grown in popularity and are currently being increasingly used on smartphone devices. Because of the quickly expanding quantity of Android malware and the potential safeguard of vast amounts of data kept on Android devices, the identification and categorization of Android malware is regarded as a big data challenge. Researchers started using deep learning (DL) techniques for malware detection, according to the most recent state-of-the-art studies. Nevertheless, researchers and practitioners face challenges such as the choice of DL architecture, extracting and processing features and evaluating results. In this paper, several traditional and hybrid machine learning (ML) models were developed and analyzed in detail to classify Android malware. First, some state-of-the-art DL model has been developed like multi-layer perceptron (MLP), deep neural network (DNN), recurrent neural network (RNN), long short-term memory (LSTM), convolutional neural network (CNN) and later several hybrid models have been developed by combining DNNs with support vector machine (SVM). Second, we have focused on maximizing achievement by fine-tuning a variety of configurations to guarantee the best possible combination of the hyper-parameters and attain the maximum statistical metric value. Finally, we have accomplished performance analysis between these hybrid models and a model based on VGG-16-CNN-1D along with SVM has been proposed to enhance the accuracy and efficacy of large-scale Android malware detection which outperforms all the other developed models using Drebin Dataset. Among the DL methods, DNN achieved the highest F1 score 99.07%. After doing a comparison between hybrid models, it was found that DNN-SVM achieved 99.12% while VGG16-CNN-1D-SVM achieved 98.56% precision, 98.78% recall and 99.20% F1 score, respectively.
Closest Pairs Search Over Data Stream

Published: November 2023

k-closest pair (KCP for short) search is a fundamental problem in database research. Given a set of d-dimensional streaming data S, KCP search aims to retrieve k pairs with the shortest distances between them. While existing works have studied continuous 1-closest pair query (i.e., k=1) over dynamic data environments, which allow for object insertions/deletions, they require high computational costs and cannot easily support KCP search with k>1. This paper investigates the problem of KCP search over data stream, aiming to incrementally maintain as few pairs as possible to support KCP search with arbitrarily k. To achieve this, we introduce the concept of NNS (short for
N

S
et), which consists of all the nearest neighbour pairs and allows us to support KCP search via only accessing O(k) objects. We further observe that in most cases, we only need to use a small portion of NNS to answer KCP search as typically kłl n. Based on this observation, we propose TNNS (short for
T
hreshold-based

S
et), which contains a small number of high-quality NN pairs, and a partition named τ-DLBP (short for τ-

Modularity-based Hypergraph Clustering: Random Hypergraph Model, Hyperedge-cluster Relation, and Computation
Authors: Feng Zijin , Qiao Miao , Cheng Hong
Published: November 2023

A graph models the connections among objects. One important graph analytical task is clustering which partitions a data graph into clusters with dense innercluster connections. A line of clustering maximizes a function called modularity. Modularity-based clustering is widely adopted on dyadic graphs due to its scalability and clustering quality which depends highly on its selection of a random graph model. The random graph model decides not only which clustering is preferred - modularity measures the quality of a clustering based on its alignment to the edges of a random graph, but also the cost of computing such an alignment. Existing random hypergraph models either measure the hyperedge-cluster alignment in an All-Or-Nothing (AON) manner, losing important group-wise information, or introduce expensive alignment computation, refraining the clustering from scaling up. This paper proposes a new random hypergraph model called Hyperedge Expansion Model (HEM), a non-AON hypergraph modularity function called Partial Innerclusteredge modularity (PI) based on HEM, a clustering algorithm called Partial Innerclusteredge Clustering (PIC) that optimizes PI, and novel computation optimizations. PIC is a scalable modularity-based hypergraph clustering that can effectively capture the non-AON hyperedge-cluster relation. Our experiments show that PIC outperforms eight state-of-the-art methods on real-world hypergraphs in terms of both clustering quality and scalability and is up to five orders of magnitude faster than the baseline methods.
OptiQL: Robust Optimistic Locking for Memory-Optimized Indexes
Authors: Shi Ge , Yan Ziyi , Wang Tianzheng
Published: November 2023

Modern memory-optimized indexes often use optimistic locks for concurrent accesses. Read operations can proceed optimistically without taking the lock, greatly improving performance on multicore CPUs. But this is at the cost of robustness against contention where many threads contend on a small set of locks, causing excessive cacheline invalidation, interconnect traffic and eventually performance collapse. Yet existing solutions often sacrifice desired properties such as compact 8-byte lock size and fairness among lock requesters.

This paper presents optimistic queuing lock (OptiQL), a new optimistic lock for database indexing to solve this problem. OptiQL extends the classic MCS lock---a fair, compact and robust mutual exclusion lock---with optimistic read capabilities for index workloads to achieve both robustness and high performance while maintaining various desirable properties. Evaluation using memory-optimized B+-trees on a 40-core, dual-socket server shows that OptiQL matches existing optimistic locks for read operations, while avoiding performance collapse under high contention.
