Learning body part‐based pose lexicons for semantic action recognition
Authors: Zhou Lijuan , Jiang Tao 
Published: September 2022

AbstractSemantic action recognition aims to classify actions based on the associated semantics, which can be applied in video captioning and human‐machine interaction. In this paper the problem is addressed by jointly learning multiple pose lexicons based on multiple body parts. Specifically, multiple visual pose models are learnt, and one visual pose model is associated with one body part, which characterises the likelihood of an observed video frame being generated from hidden visual poses. Moreover, multiple pose lexicon models are simultaneously learnt along with visual pose models. One pose lexicon model is associated with one body part that establishes a probabilistic mapping between the hidden visual poses and semantic poses parsed from textual instructions. To capture the temporal relations among body parts, a transition model is also learnt to measure the probability of the alignment transitioned from one position to another position. The body part‐based pose lexicon learning provides a novel method of cross‐modality semantic correlation, which can be applied in other spatial and temporal data. Action classification is finally formulated as the problem of finding the maximum posterior probability that a given multiple sequences of visual frames follow multiple sequences of semantic poses, subject to the most likely visual pose sequences and alignment sequences. Experiments were conducted on five action datasets to validate the effectiveness of the proposed method.

AbstractIn this letter, the jamming resource allocation problem of distributed jammers cooperatively jamming netted radar system is investigated. A well‐constructed jamming resource allocation model considering jamming beams, jamming power and other influencing factors is established. Random keys are used in this letter to improve the coding mode of genetic algorithm. Simulation results show that in the case of limited jamming resources, the model and algorithm proposed can achieve effective jamming allocation schemes facing a netted radar with any number of radar nodes.
Absolute colors and phase coefficients of asteroids

Published: September 2022

Context. We use the phase curves of small bodies to measure absolute magnitudes and, together with complementary theoretical and laboratory results, to understand the micro- and macroscopic properties of their surfaces. Although we can observe asteroids up to phase angles of about 30 deg, the range of phase angles covered by outer Solar System objects usually does not go further than 7−10 deg for centaurs and 2 deg for trans-Neptunian objects, and a linear relation between magnitude and phase angle may be assumed.
Aims. We aim to directly compare data taken for objects in the inner Solar System (inside the orbit of Jupiter) with data for centaurs and trans-Neptunian objects.
Methods. We use the SLOAN Moving Objects Catalog (MOC) data to construct phase curves restricted to phase angles of less than or equal to 7.5 deg, which is compatible with the angles observed for the trans-Neptunian and Centaur population. We assume a linear model for the photometric behavior to obtain absolute magnitudes and phase coefficients in the ugirz, V, and R filters.
Results. We obtain absolute magnitudes in seven filters for over 4000 objects. Our comparison with outer Solar System objects suggests the surfaces have a common property: intrinsically redder objects become blue with increasing phase angle, while the opposite happens for intrinsically bluer objects.

AbstractA deaminative alkyl radical cascade cyclization of 1,7-dienes is described under visible-light photocatalysis. This method delivers a family of benzoazepinones (benzazepinones) and occurs under mild reaction conditions to access a broad substrate scope with excellent functional group tolerance and good yields. This protocol has also been extended to 1,7-enynes, furnishing a representative collection of cyclopentaquinolinones.
Ring-System-Based Conformational Switches and their Applications in Sensing and Liposomal Drug Delivery
Authors: Pedersen Christian Marcus , Su Hang 
Published: September 2022

AbstractIn the past decades, a great number of stimuli-responsive systems have been developed to be used as drug-delivery systems with high sensitivity and selectivity in targeted therapy. Despite promising results, the current stimuli-responsive systems suffer from the complexity of preparation, as most novel stimuli-responsive systems are based on polymers. Small molecules have often been neglected as candidates for application for stimuli-responsive systems. Recently, structures based on six-membered ring molecules or bicyclic molecules have been developed into conformational switches working through conformational interconversion. These single conformational switches have significantly reduced the complexity of material preparation compared to polymers or copolymers. In this review, we focus on ring-system-based conformational switches that are involved in sensors and smart drug-delivery systems. We hope that this review will shed light on ring-system-based single conformational switches for use in the development of stimuli-responsive systems.1 Introduction2 Conformation Switches Based On Bispidine Derivatives3 Conformation Switches Based On Cycloalkanes4 Conformation Switches Based On Carbohydrates5 Conclusion

AbstractOvarian malignancy is the seventh most frequently diagnosed cancer among women. The most common type is epithelial ovarian cancer. Several subtypes with distinct biological and molecular properties exist, and there is inconsistency in availability of and access to different modalities of treatment. The standard first-line management is combining surgery and platinum-based chemotherapy. Most of them are diagnosed at an advanced stage due to which they have poor outcomes. The existing screening tests have a low predictive value. Even with the best available upfront treatment, high rates of recurrences are observed. As a result, there have been major advances in the treatment of recurrences with the development of anti-angiogenic agents and PARP inhibitors. It has led to the improvement in survival and quality of life among the relapsed epithelial ovarian cancers. This review is focused on the management of recurrent epithelial ovarian cancers and future directions based on current evidence. The application of a personalized and structured approach will meaningfully bring changes in the paradigm of care in these groups of patients.
Immobilization of Solvatochromic Dyes on Transparent Cellulose Films: an Improved Method for the Study of Homeopathic Potencies
Authors: Cartwright Steven J. 
Published: September 2022

Abstract
Background Highly diluted and succussed solutions (homeopathic potencies) have been shown to interact with a wide range of solvatochromic dyes based on changes in their UV-visible spectra. Studies so far have involved free dyes in solution, but there is a pressing need to find ways to investigate the potency–dye interaction using isolated dye molecules to ask more searching physico-chemical questions regarding the fundamental nature of potencies.
Aims and Methods The aims of the present study have been to look for ways to covalently immobilize solvatochromic dyes onto transparent cellulose films and hence be in a position to investigate dye–potency interactions without the complication of dye–dye interactions, including dye aggregation, which can occur with free dyes in solution.
Results To date, a total of nine different dyes have been immobilized on cellulose films using epoxide activation of hydroxyl groups on the cellulose surface. Using this method, studies have begun looking at the time course of potency action on one of these immobilized dyes, Brooker's merocyanine. Results show that the interaction of Arsenicum 10M with this dye consists of three phases—an initial growth phase, a sustained plateau of interaction, and a final decline phase lasting several days.
Conclusion A method has been developed that successfully immobilizes solvatochromic dyes onto transparent cellulose film. These films can then be used in a spectrophotometer to study at a much more detailed level how potencies interact with dyes compared with using free dyes in solution. Results indicate that the information gained in this way provides new insights regarding the fundamental nature of potencies. Specifically, studies using immobilized Brooker's merocyanine with Arsenicum 10M reveal that the lifetime of the potency is much longer than expected and that its action consists of three distinct phases, suggesting a resonant interaction with the dye. How resonant interaction might help to explain the clinical action of potencies is discussed.

Published: September 2022

Objective Infants in the neonatal intensive care unit (NICU) are at high risk of adverse neuromotor outcomes. Atypical patterns of heart rate (HR) and pulse oximetry (SpO2) may serve as biomarkers for risk assessment for cerebral palsy (CP). The purpose of this study was to determine whether atypical HR and SpO2 patterns in NICU patients add to clinical variables predicting later diagnosis of CP.
Study Design This was a retrospective study including patients admitted to a level IV NICU from 2009 to 2017 with archived cardiorespiratory data in the first 7 days from birth to follow-up at >2 years of age. The mean, standard deviation (SD), skewness, kurtosis and cross-correlation of HR and SpO2 were calculated. Three predictive models were developed using least absolute shrinkage and selection operator regression (clinical, cardiorespiratory and combined model), and their performance for predicting CP was evaluated.
Results Seventy infants with CP and 1,733 controls met inclusion criteria for a 3.8% population prevalence. Area under the receiver operating characteristic curve for CP prediction was 0.7524 for the clinical model, 0.7419 for the vital sign model, and 0.7725 for the combined model. Variables included in the combined model were lower maternal age, outborn delivery, lower 5-minute Apgar's score, lower SD of HR, and more negative skewness of HR.
Conclusion In this study including NICU patients of all gestational ages, HR but not SpO2 patterns added to clinical variables to predict the eventual diagnosis of CP. Identification of risk of CP within the first few days of life could result in improved therapy resource allocation and risk stratification in clinical trials of new therapeutics.

Published: September 2022

AbstractStudies from the past 50 years have contributed to the expanding knowledge regarding developmental hemostasis. This is a dynamic process that begins in the fetal phase and is characterized by physiological variations in platelet counts and function, and concentrations of most coagulation factors and the native coagulation inhibitors in early life, as compared with adulthood. The developmental hemostasis studies since the 1980 to 1990s established the laboratory reference values for coagulation factors. It was only a decade or two later, that thromboelastography (TEG) or (rotational thromboelastometry [ROTEM]) as well as thrombin generation studies, provided special pediatric reference values along with the ability to evaluate clot formation and lysis. In addition, global whole blood-based clotting assays provided point of care guidance for proper transfusion support to children hospitalized in intensive care units or undergoing surgery. Although uncommon, thrombosis in children and neonates is gaining increasing recognition, typically as a secondary complication in sick children. Bleeding in children, and particularly intracerebral hemorrhage in newborns, still represent a therapeutic challenge. Notably, our review will outline the advancements in understanding developmental hemostasis and its manifestations, with respect to the pathophysiology of thrombosis and bleeding complications in young children. The changes of transfusion policy and approach to thrombophilia testing during the last decade will be mentioned. Subsequently, a brief summary of the data on anticoagulant treatments in pediatric patients will be presented. Finally, we will point out the 10 most cited articles in the field of pediatric and neonatal hemostasis.

Published: September 2022

AbstractAnticoagulant therapy is essential in pregnant women with mechanical heart valves to prevent valve thrombosis. The risk of bleeding complications in these patients has not gained much attention. This systematic review and meta-analysis investigate the prevalence of bleeding peri-partum and post-partum in women with mechanical heart valves and also investigate whether bleeding risk differed across anticoagulant regimens or according to delivery mode. The present study was conducted according to The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. Studies reporting bleeding prevalence in pregnant women with mechanical heart valves receiving anticoagulant therapy were identified through PubMed and Embase on December 08, 2021. Data on bleeding complications, delivery mode, and anticoagulation therapy were extracted. A total of 37 studies were included, reporting 423 bleeding complications in 2,508 pregnancies. A meta-analysis calculated a pooled prevalence of 0.13 (95% confidence interval [CI]: 0.09–0.18) bleeding episodes per pregnancy across anticoagulant regimens. The combination of unfractionated heparin (UFH) and vitamin K antagonist (VKA) and single VKA therapy showed the lowest risk of bleeding (8 and 12%). Unexpectedly, the highest risk of bleeding was found in women receiving a combination of low-molecular-weight-heparin (LMWH) and VKA (33%) or mono-therapy with LMWH (22%). However, this could be dose related. No difference in bleeding was found between caesarean section versus vaginal delivery (p = 0.08). In conclusion, bleeding episodes are common during pregnancy in women with mechanical heart valves receiving anticoagulant therapy. A combination of UFH and VKA or VKA monotherapy showed the lowest risk of bleeding.

Our goal is to provide health professionals with more recent knowledge and recommendations for better rehabilitation care after stroke.
Analyzing the past, improving the future: a multiscale opinion tracking model for optimizing business performance
Authors: Sigari Salman , Gandomi Amir. H. 
Published: September 2022

AbstractThe complexity of business decision-making has increased over the years. It is essential for managers to gain a confident understanding of their business environments in order to make successful decisions. With the growth of opinion-rich web resources such as social media, discussion forums, review sites, news corpora, and blogs available on the internet, product and service reviews have become an essential source of information. In a data-driven world, they will improve services and operational insights to achieve real business benefits and help enterprises remain competitive. Despite the prevalence of textual data, few studies have demonstrated the effectiveness of real-time text mining and reporting tools in firms and organizations. To address this aspect of decision-making, we have developed and evaluated an unsupervised learning system to automatically extract and classify topics and their emotion score in text streams. Data were collected from commercial websites, open-access databases, and social networks to train the model. In the experiment, the polarity score was quantified at four different levels: word, sentence, paragraph, and the entire text using Latent Dirichlet Allocation (LDA). Using subjective data mining, we demonstrate how to extract, summarize, and track various aspects of information from the Web and help traditional information retrieval (IR) systems to capture more information. An opinion tracking system presented by our model extracts subjective information, classifies them, and tracks opinions by utilizing location, time, and reviewers’ positions. Using the online-offline data collection technique, we can update the library topic in real-time to provide users with a market opinion tracker. For marketing or economic research, this approach may be useful. In the experiment, the new model is applied to a case study to demonstrate how the business process improves.
Antisemitic comments on Facebook pages of leading British, French, and German media outlets

Published: September 2022

AbstractWe conducted a cross-national study on antisemitic hate speech on theFacebookprofiles of leading media outlets in the United Kingdom, France, and Germany. In a combination of qualitative pragmalinguistic analysis and quantitative analysis, we examined their comment sections concerning the conceptual and linguistic repertoire of verbal antisemitism in these three languages as well as to the frequency of antisemitic utterances. The corpus comprises 4500 comments (1500 for each language) made in reaction to the media’sFacebookposts reporting on an escalation phase of the Arab–Israeli conflict in May 2021. Since in antisemitism studies, Israel—and issues related to it—are widely perceived as today’s main pretext for communicating antisemitic resentment, unsurprisingly, those events led to the emergence of antisemitic content online. This article contrasts the findings of antisemitism in the three countries’ comment sections and illustrates them by presenting a variety of linguistic realisations of various antisemitic concepts and illustrates the corresponding steps of interpretation.
The relationship between leadership style and staff work engagement: An empirical analysis of the public sector in Vietnam

Published: September 2022

AbstractThis analysis explores the relationship between transformational, transactional, and laissez-faire leadership styles with staff work engagement at the department level in the public sector in Vietnam. Using a cluster sampling method, a total of 378 participants were selected and agreed to participate in a survey by completing a questionnaire on the relationship between leadership style and work engagement. All participants are attendees of a training course for department-level leaders at the School of Culture, Sports, and Tourism Administration Officers under the Ministry of Culture, Sports, and Tourism of Vietnam. A regression was run on the collected data to test the hypothesis on the relationship between leadership styles and staff task performance. The regression results show that there is a significant indirect relationship between staff work engagement and innovative work behavior and task performance. In addition, there is a relatively positive relationship between the transformational leadership style and transactional leadership style of the department-level leaders in the Vietnamese public sector with staff work engagement, particularly innovative work behavior and task performance. On the contrary, laissez-faire leadership style negatively impacts staff work engagement and innovative work behavior. Staff work engagement is an integral part of the relationship between leadership style and leadership effectiveness. The findings suggest that the Vietnamese public sector should aim to identify transformational and transactional leaders. This research focuses on the department level and is limited to three leadership styles (transformational, transactional, and laissez-faire) only. Future research therefore can expand the scope to higher levels than the department leaders.
