Published: July 2022

BACKGROUND:

The efficacy of endovascular recanalization for internal carotid artery (ICA) terminus occlusion has not been completely evaluated.

OBJECTIVE:

To investigate the efficacy of endovascular recanalization for ICA terminus occlusion.

METHODS:

Data from Direct-MT, a randomized controlled trial, were applied. ICA terminus occlusions were diagnosed with preprocedure computed tomography angiography by the core laboratory. We dichotomized the ICA terminus occlusions into 2 groups (non-T and T) and analyzed the differences between them. Single-factor analysis and multiple logistic regression were applied to detect independent factors for clinical outcomes and futile recanalization.

RESULTS:

The rates of first-pass effect, successful recanalization, good clinical outcome, mortality, and futile recanalization were 22.3% (50 of 224), 83.0% (181 of 224), 24.6% (55 of 224), 26.7% (60 of 224), and 69.6% (126 of 181), respectively. Baseline National Institutes of Health Stroke Scale (negative factor; odds ratio [OR] 0.89; 95% CI 0.84-0.95; P < .001), hypertension (negative factor; OR 0.38; 95% CI 0.18-0.80; P = .010), Alberta Stroke Program Early CT Score ≥ 6 (OR 3.68; 95% CI 1.29-10.5; P = .014), tirofiban use (OR 2.46; 95% CI 1.16-5.19; P = .018), first-pass effect (OR 2.87; 95% CI 1.28-6.41; P = .010), and final extended thrombolysis in cerebral infarction ≥ 2b (OR, 3.50; 95% CI 1.17-10.4; P = .024) were independent factors for good clinical outcome. Baseline National Institutes of Health Stroke Scale (OR 1.12; 95% CI 1.05-1.20; P = .004), Alberta Stroke Program Early CT Score < 6 (OR 4.68; 95% CI 1.51-14.5; P = .007), tirofiban use (negative factor; OR 0.39; 95% CI 0.18-0.86; P = .020), and first-pass effect (negative factor; OR 0.44; 95% CI 0.19-0.99; P = .047) were independent factors for futile recanalization.

CONCLUSION:

More efforts in modifiable factors should be made to improve the efficacy of endovascular recanalization for better clinical outcomes and less futile recanalization in ICA terminus occlusions.

Authors: Saikia Monalisa , George Linu Sara , Unnikrishnan Bhaskaran , George Anice , Ravishankar N
Published: July 2022

Background: Staff nurses face frequent emotional situations in their work environment. The constant contact with suffering patients, and the busy work environment, pose tremendous stress on nurses' physical and emotional health. The Emotional Intelligence skills of empathy, self-awareness, motivation, self-control, and keeping relationships, can help handle difficult emotions and allow nurses to work in an organized, calm, and professional way.

This study aims to implement and assess the effectiveness of a training program developed by the investigator, tailored to the mental and emotional needs of staff nurses who are working in an organisation. The study also aims to observe any significant change, correlation, and association in the staff nurses’ level of emotional intelligence, intrinsic motivation, self-compassion, emotional labour, and nurse-in-charges’ and patients’ perception of nursing care after the program.

Methods: A quasi-experimental (one-group) study design will be used in this study. The study will involve 80 staff nurses working in a selected hospital in India. The staff nurses will be selected from the hospital's general wards using convenience sampling. The investigator will deliver a training program, divided into four sessions of two hours each. Data will be collected from the participants at baseline and 3-months pre-intervention; and post-test data will be collected immediately after the intervention, at 3-month, and 6-month follow-up, to observe any significant change in the study variables before and after the intervention.

Results: The current study primarily focuses on the vital aspect of developing emotional needs, for promoting a better work-life balance. Research findings from the study will significantly contribute to the evidence-based Emotional Intelligence programs for staff nurses, and if proven effective, could be delivered extensively in hospitals.

Feasibility and effectiveness of exercise-based prehabilitation in patients opting for elective abdominal surgeries: A pre-post study
Authors: Noronha Jean Nikitha , Samuel Stephen Rajan , Singh Vijay Pratap , Prabhu H Shivananda
Published: July 2022

Background: Surgical procedures are accompanied by various complications such as decreased respiratory muscle strength, decreased functional capacity, decreased quality of life, and increased the length of hospital stay. There is a growing body of evidence that indicates that exercise-based prehabilitation offered before major abdominal surgeries can improve the above-mentioned complications. Considering the socioeconomic inequalities, educational characteristics, and healthcare system, which are different in low and lower-middle income countries, it is important to know whether interventions such as prehabilitation are feasible and effective in patients undergoing elective abdominal surgeries. Hence, we set out to determine the role of exercise-based prehabilitation in patients opting for these surgeries.

Methods: In this feasibility study, 71% of the eligible patients agreed to participate. Baseline values of respiratory muscle strength, functional capacity and quality of life were recorded preoperatively, and an exercise-based prehabilitation programme consisting of chest physiotherapy, aerobic exercises and inspiratory muscle training according to the patient’s capacity was administered until the day of surgery. A total of 62% of the participants completed the study whose postoperative values and a user satisfaction scale were noted. The feasibility parameters  of recruitment rate, dropout rates, adherence events, adverse events and participants satisfaction were evaluated and the differences in the preoperative and postoperative values of respiratory muscle strength, functional capacity and quality of life  were calculated using the paired t-test  accordingly.

Results: Feasibility was measured using five parameters. All the values were > 50% and above. The secondary variables respiratory muscle strength, functional capacity, and quality of life were not significant.

Conclusions: This study concluded that prehabilitation is feasible and can be effectively delivered to patients scheduled for elective abdominal surgery.

The gaming problem: A latent class analysis of DSM-5 criteria for Internet Gaming Disorder in a non-clinical sample
Authors: Raybould Jodie , Watling Dylan , Larkin Michael , Tunney Richard
Published: July 2022

Background: In this study we aimed to test whether suggested DSM-5 criteria for Internet Gaming Disorder (IGD) share a similar latent structure to formally recognised addiction.

Methods: We used latent class analysis on a dichotomous measure of IGD. The data was collected from a convenient general population sample (500) and a targeted gaming forum sample (236).

Results: We found a four or six-class model to be most appropriate, ranging from ‘casual/non-gamer’ to ‘potentially disordered’ with increasing symptom severity. The majority of ‘potentially disordered’ gamers (5+ criteria) were found to be 18-30 years old, and no ‘potentially disordered’ gamers were over 42.

Conclusions: The results suggest that gaming may share a similar latent structure to established addictions, with adolescents and young adults being more at risk. Studies replicating these results would be beneficial, with further emphasis on a critical evaluation of the criteria and symptom cut-off point.

Authors: Ronse Maya , Nieto-Sanchez Claudia , De Coninck Sien , Verdonck Kristien , Peeters Grietens Koen
Published: July 2022

Despite difficulties to document transmission pathways (assumed to be airborne), increased risk of leprosy infection has been shown for individuals living in close contact with patients. However, variations in the concept of ‘close contacts’ are used in different settings and studies. We conduct this review to identify criteria of space (location, geographical variables, distance, indoor vs outdoor), time (including frequency and duration), physical exposure (skin to skin, sexual), and relationship (familial, occupational, social) involved in the definition of ‘close contacts’ in leprosy studies. We expect this review to provide an overview of the (lack of) conceptualization of this term and its variations across settings. Primary studies and reviews are eligible for inclusion in this review. The main source of records will be the PubMed interface. Secondary searches will be conducted in Google Scholar, as well as through the reference lists of selected publications. The search strategy is based on the combination of the condition of interest (leprosy) and the concept under study (‘contact’). The findings of this review will be presented using thematic narrative synthesis, tables, and figures. The protocol is written in line with the Prisma Extension for Scoping reviews (PRISMA-ScR).

Authors: Salimah Aisyah , Hazmi Miftah , Fathur Rouf Hasan Muhammad , Agung Putera Agung Maha , Yelvi .
Published: July 2022

Background: The role of soil in building construction is to support the loads above it. Different types of soil with poor mechanical properties require more attention. Therefore, more effort is needed to stabilize the soil by improving its properties. These improvements are intended to modify soil properties to improve engineering performance, such as strength, decrease in compressibility and permeability. This study aimed to compare the potential of lime and brick powder as stabilizers based on the California Bearing Ratio (CBR) values. Soil stabilization can be defined as modifying the soil properties by chemical or physical means to improve its engineering efficiency. The main objectives of stabilizing soil are increasing its bearing capacity, resistance to weathering processes, and permeability.

Methods: This work did laboratory tests with disturbed and undisturbed soil samples. The proportions of lime or red brick powder additives are 0%, 5%, 10%, and 15% of the soil sample. From the results of the laboratory tests, the soil type obtained is MH (low plasticity silt) as per the Unified Soil Classification System (USCS).

Results: This study showed that soft soil could be improved by adding lime and red brick powder as a soil stabilizer. In both soaked and unsoaked CBR tests, there was an increase in the CBR value for each proportion of the mixed additives. However, the red brick powder addition (15%) has significantly increased the CBR value.

Conclusions: The soil sample mixed with 15% red brick powder had the highest Maximum Dry Density (MDD), about 5.5% over untreated soil. The increment of lime to 15% has increased the CBR soaked by 61% in relation to untreated soil. The increment of red brick powder to 15% has increased the CBR unsoaked by 73% in relation to untreated soil.

Authors: Hassan Tarteel , Bashir Razan A. , Abdelrahman Dina N. , Madni Hassan , M El Hussein Abdel Rahim , Elkidir Isam M. , Enan Khalid A.
Published: July 2022

Background: Because of yellow fever’s serious impact on health, vaccination is the principal strategy to control the disease. Administration of the yellow fever vaccine to breastfeeding women should be before they complete 9 months post-delivery, in order to prevent transmission of the yellow fever vaccine virus to their infants through breast feeding. This study aimed to confirm whether the excretion of yellow fever vaccine virus is in milk of vaccinated breastfeeding mothers and to confirm the probable transmission to their infants through breast milk.

Methods: Samples were taken as follows: one serum specimen was taken 3-14 days after the date of the vaccination, and breast milk specimens were taken at four different time points between 3-4 days apart. Specimens were obtained from eight nursing mothers, who received the YVF vaccine (17DD). Mothers were asymptomatic before and after the vaccine administration but their infants developed symptoms after administration. Maternal serum samples were tested for YFV specific IgM antibodies through immuno-fluorescent assay (IFA). RNA was extracted from serum and breast milk specimens and YFV RNA screened using real-time polymerase chain reaction (RT-PCR).

Results: In total, five mothers (62.5%) were positive for YFV IgM and two mothers (25%) had YFV RNA in serum. Among milk specimens, YFV RNA was detected during the four different mentioned collection times as follows (positive milk specimens/total milk specimens): 3/8 (37.5 %), 4/6 (66.6%) and 1/4(25%). RNA was completely undetectable in the last collection time.

Conclusions: YFV transmission from mothers to their babies through breast-feeding was highly probable indicated by the temporal relationship to mother’s YF vaccination.
Effective inter-organisational networks for Responsible Research and Innovation and global sustainability: a scoping review
Authors: Farrugia Danielle Martine , Vilches Silvia Leonor , Gerber Alexander
Published: July 2022

Background: Achieving the United Nations Sustainable Development Goals (SDGs) is beyond the capacity of any single organisation. The model for Responsible Research and Innovation (RRI) includes principles of engaging stakeholders and suggests that an engaged, multi-sectoral approach hold promise to mobilise humanity to solve complex and urgent global issues.

Methods: This scoping review explores the characteristics of effective and sustainable inter-organisational networks for fostering RRI in service of the SDGs. An inductive-deductive search of prior studies (1990-2020), with the exception of Benson’s (1975) seminal work was conducted, which focused on strategies to initiate and maintain inter-organisational networks relevant to the implementation of RRI and/or SDGs. The search began with themes derived from prior network theory, focusing on: (a) the type and function of networks; (b) the aims and vision; and (c) the relationships between networks and network members. In total, 55 articles on inter-organisational network theory were included for the final analysis.

Results: Results are reported under themes of: (1) Effectiveness, Sustainability, and Success; (2) Governance and Management; and (3) Network Relationship. Network structures, forms of management and funding are linked to sustainable networks. Potential threats include power imbalances within networks, and internal and external factors that may affect relationships at network and community levels. Few studies examine diversity or cultural viewpoints. Studies highlight the benefits of networks such as enhancing knowledge sharing among researchers, practitioners, and other stakeholders.

Conclusions: The effectiveness of the managerial structure may be observed as outputs of the intention and values of an inter-organisational network. Our review demonstrates that a global inter-organisational network approach is achievable. Such a network would have many benefits, including allowing organisations to be responsive and flexible towards change and innovation.

Algorithmic Interactions in Open Source Work
Authors: Shaikh Maha , Vaast Emmanuelle
Published: July 2022

This study focuses on algorithmic interactions in open source work. Algorithms are essential in open source because they remedy concerns incompletely addressed by parallel development or modularity. Following algorithmic interactions in open source allows us to map the operational performance of algorithms to understand how algorithms work with multiple other algorithms to accomplish work. Studying algorithms working together shows us how residual interdependencies of modularity and problems not resolved by dependence on parallel development are worked around to perform open source work. We examine the Linux Kernel case that reveals how algorithmic interactions facilitate open source work through the three processes of managing, organizing, and supervising development work. Our qualitative study theorizes how algorithmic interactions intensify through these processes that work together to facilitate development. We make a theoretical contribution to open source scholarship by explaining how algorithmic interactions navigate across module rigidity and enhance parallel development. Our work also reveals how, in open source, developers work to automate most tasks and augmentation is a bidirectional relationship of algorithms augmenting the work of developers and of developers augmenting the work of algorithms.

Authors: Karniouchina Ekaterina , Carson Stephen J. , Moore William L. , Sarangee Kumar R. , Uslay Can
Published: July 2022

This study examines whether the benefits of diversification vary across different value chain activities. The returns to diversification in product development and distribution activities are analyzed using a framework grounded in the intraindustry diversification literature and the resource-based view (RBV) of the firm. The study uses data from cocreation arrangements in the motion picture industry in which value chain activities are nearly decomposable—that is, split across producers and distributors—as a natural field study. Results based on 779 movies linked to 57 different production studios and distributed via 30 unaffiliated distributors or vertically integrated distribution branches show that greater focus in film production has a positive effect on profitability, whereas the level of focus/diversification in distribution is unrelated to profitability. This result holds regardless of whether the two functions are carried out within an integrated organization or across independent firms. Moreover, there is significant heterogeneity in the extent to which production studios benefit from increased focus which is tied to the composition of their product portfolios.

Formation of Volitional Properties During Physical Culture Lessons
Authors:   State Institution Luhansk Taras Shevchenko National University, Polulyaschenko Tetiana
Published: July 2022

The article is devoted to the understudied challenges of establishing the pedagogical conditions for training students' volitional traits in physical activities. Recent research and publications on pedagogical circumstances are emphasized, and the terms «condition» and «pedagogical condition» are defined. This article reveals the critical role of educational settings in the development of volitional characteristics during physical workouts. The main goals of this article are to emphasize the significance of researching the essence of pedagogical conditions in the process of developing volitional qualities in physical exercises, as well as to identify the relationship between the development of volitional qualities and the level of physical fitness. The idea of «will» is defined as a person's conscious organization and self-regulation that allows him to regulate his feelings, behaviors, and cognitive processes. The qualities that characterize a person's volitional sphere are defined within the framework of the volitional sphere. The essence and benefits of physical exercise as a means of self-affirmation and self-expression are described, both physiologically and morally. The relationship between physical fitness has been investigated and established. The better the physical fitness, the more purposefully, persistently, decisively and boldly the behavior of students in physical exercises becomes, the more actively they take part in independent physical exercises. The obtained results were revealed in the study of correlations between the general volitional preparedness of students and the performance indicators of physical fitness tests. According to the results of the study, the article presents the results of an experimental study, which allows us to consider that pedagogical conditions are an important component in the education of the volitional qualities of young students. In this study, the conditions for the formation of volitional qualities were considered from two directions: organizational-pedagogical and psychological-pedagogical conditions. The study's findings confirm that involving students in individual physical activities helps them develop strong-willed attributes including purposefulness, tenacity and perseverance, endurance and self-control, initiative and independence. Purposeful activities for the education of volitional qualities of students provide for the organization of their training in such a way as to ensure flexible manifestations of the structure of volitional qualities that have certain differences when conducting independent studies in manifestations of initiative and independence. More research is being planned to perform a more in-depth examination of this issue.
Educational Innovations: Formation of the Categorical-Conceptual Apparatus, Stages and Laws of Flow
Authors:   State University of Physical Education and Sports of the Republic of Moldova, Polyakova Varvara
Published: July 2022

Modern society is distinguished by ongoing innovation processes, since innovation activity is a necessary condition for economic growth and improving the quality of life in any country. In this regard, education has not bypassed innovative activity. This article discusses the retrospective of the formation of the concept of «innovation». The progenitor of the definition of «innovation» was the term «novation». For the first time, the concept of «novation» appeared in legal documents of the 13th century. and denoted the obligations of the parties to replace one agreement they signed with another, which did not imply the invention of something, but simply novelty. As a self-sufficient term, the definition of «innovation» began to assert itself in the 19th century, in connection with the development of science, technology, and the industrial revolution. As a scientific term, the concept of «innovation» received its purpose at the beginning of the 20th century in the works of the Austrian economist Joseph Alois Schumpeter, which was the result of an analysis of «innovative combinations», changes in the development of economic systems. With the development of the economy, the definition of «innovation» has expanded its boundaries of understanding. Since the end of the 1950s, innovation processes in pedagogy have also been studied. In relation to the pedagogical process, innovation means the introduction of innovation in the goals, content, methods, forms of education and upbringing, as well as in the organization of joint activities of the teacher and students. There are four laws of the flow of innovation processes: irreversible destabilization of the pedagogical innovation environment; final implementation of the innovation process; stereotyping of pedagogical innovations; cyclic repeatability, recurrence of pedagogical innovations.

Published: July 2022

The article is devoted to the research of the problem of future teachers of physical education’s creative personality formation features. The goal of the article is to theoretically substantiate the future teachers of physical education’s creative personality formation peculiarities during their study in Higher educational institutions. The article goes into qualities that may serve for estimation of the future PF teacher’s individual personality traits such as ideological and political, moral, volitional, behavior in the team, attitude to work, personal and professional. The components of the pedagogical creativity of a physical education teacher are the experience of creative activity, which gives confidence in the correctness of the chosen way of communication with students and direct interaction with them (based on the creative potential of the individual); psychological, pedagogical and special knowledge; creativity, new ideas that allow someone to find and apply distinctive and non-standard solutions in its professional activity; motion experience as a specific indicator, without which it is impossible to talk about the professional suitability of a physical education teacher. For the increase of motivation of the creative activity of students of higher educational institutions specialty “Secondary education. (Physical Education)” it is perceived to attract them to research work and continuous practice starting from 2nd year. It is recommended to put the focus on creative approach towards tasks in the process of their theoretical training by mastering the system of necessary theoretical knowledge; to develop special systems of creative tasks and types of work that bring students of higher educational institutions to the tasks and methods of the teacher’s performance on the level of proficiency and innovation. To develop creative approach towards future teachers of PR’s professional activity it is necessary to implement the system of problem tasks (theoretical, practical, set of movements) into the educational process in all the disciplines. The system of problem tasks is based on methods that stimulate thinking outside the box and shows the problems of PE Teacher’s activity in a real way.

The article discusses the motives of the technological combination of pedagogical influence on the physical and mental development of a person by musical and motor fitness means. The integration orientation of Ukraine to the European educational space is accelerating with the pace of introduction of physical systems of the target sense, one of the sources of movement of which is fitness culture. The totality of fitness systems has the general qualities of adaptability to the physical and mental development of a person, health-improving and medical effects and recreational effects at the same time. It has an extensive network of perception of the philosophy of the developing movement of a person along the steps of physical improvement, supported by technical solutions, a stream of inventions, means of physical development of a person, his organs and life support systems. It has been established that the corresponding movement is provided externally by the quality of the pedagogical and educational process, the effectiveness of which depends on the motor action and elements of physiological ordering. Student youth success is achieved due to the coordination of motor loads and the rhythm of choreographic musical accompaniment, which in their totality are the resultant powerful developing energy. In Ukraine, the formation of information support for fitness is updated according to the logistics of choosing a set of exercises, understanding the functional features of an action, forming a desire to assimilate them and reproduce classes that correspond to the complexity of the bachelor's and master's levels. Educational technologies are replenished with management processes based on the values of the motives of health improvement, rehabilitation and physical improvement of a person. Prospects for the movement of fitness are associated with the dosage of the load on the individual according to the composition of the high-interval intensive fat-burning training technology, or a systematic approach consisting of one physical exercise, or selective physical activity in the bosom of nature.

Advanced clinical practitioners’ inter-shift need for recovery: a cross-sectional survey in emergency medicine
Authors: Fenwick Rob , Price Rebecca , Kershaw Tanya , Boddy Rachael , Chessum Peter ,   on behalf of the ACP I-NFR collaborators
Published: July 2022

Background:

Healthcare settings are high-risk environments for fatigue and staff burnout. The Need For Recovery (NFR) scale quantifies inter-shift recovery, which contributes to cumulative fatigue and may precede occupational burnout. Advanced clinical practitioners (ACPs) are an established feature of the emergency medicine workforce in the UK, however, little is known about factors affecting their inter-shift recovery, fatigue or how NFR correlates with formal burnout inventories.

Methods:

A prospective cross-sectional online survey of UK emergency medicine ACPs from 1 September to 30 September 2020. The primary aim was to determine the NFR of these ACPs. The secondary aims were to determine any statistical associations between NFR and selected variables, and whether NFR could reliably predict burnout using the Copenhagen Burnout Inventory (CBI) as a comparator.

Results:

There were 529 responses to the survey from 50 sites (response rate: 88%). The median NFR was 63.6 (95% CI 54.5–63.6). Lower NFR scores were found in ACPs who see both adults and children (54.5, 95% CI 45.4-63.6), work shifts of 7–10 hours (54.5, 95% CI 36.3–63.6) and who found it easy to park before work (54.5, 95% CI 45.5–54.5). Linear regression modelling indicated significant associations between shift length, ease of parking, ability to get breaks and feeling overwhelmed. Spearman's rho between NFR and CBI for personal and work-related burnout was 0.741 and 0.766 respectively. Correlation between NFR and patient-related burnout was less at 0.471.

Conclusion:

This study has shown the second highest NFR score reported in any occupational group. Several factors have been identified that may potentially reduce NFR and could be changed by organisations. NFR could also be used to identify those suffering with occupational burnout.

Despite the increasing popularity of midline catheters, data on the use of alteplase for restoring midline catheter patency is scarce.

Aims:

This study aimed to evaluate off-label use of alteplase for midline catheter occlusions.

Method:

Adults who received alteplase into a midline catheter between January 2015 and May 2018 within a multi-hospital health system were included in this study. The primary outcome was restoration of infusion or withdrawal function from at least one lumen of a treated midline catheter.

Findings:

Following alteplase administration, withdrawal function was restored in 47% (25/53) of occlusion events, infusion function was restored in 65% (11/17) of complete occlusion events, and infusion or withdrawal function was restored in 58% (31/53) of occlusion events. Only 34% (17/50) of catheters were replaced because of malfunction. Local bleeding was documented in 9% (n=5) of occlusion events after alteplase administration.

Conclusion:

Most midline catheter occlusions treated with alteplase demonstrated restoration of infusion or withdrawal function.

The foveal cone mosaic can be directly visualized using adaptive optics scanning light ophthalmoscopy (AOSLO). Previous studies in individuals with normal vision report wide variability in the topography of the foveal cone mosaic, especially the value of peak cone density (PCD). While these studies often involve a human grader, there have been no studies examining intergrader reproducibility of foveal cone mosaic metrics. Here we re-analyzed published AOSLO foveal cone images from 44 individuals to assess the relationship between the cone density centroid (CDC) location and the location of PCD. Across 5 graders with variable experience, we found a measurement error of 11.7% in PCD estimates and higher intergrader reproducibility of CDC location compared to PCD location (p < 0.0001). These estimates of measurement error can be used in future studies of the foveal cone mosaic, and our results support use of the CDC location as a more reproducible anchor for cross-modality analyses.

Acoustic resolution photoacoustic microscopy (AR-PAM) is a major modality of photoacoustic imaging. It can non-invasively provide high-resolution morphological and functional information about biological tissues. However, the image quality of AR-PAM degrades rapidly when the targets move far away from the focus. Although some works have been conducted to extend the high-resolution imaging depth of AR-PAM, most of them have a small focal point requirement, which is generally not satisfied in a regular AR-PAM system. Therefore, we propose a two-stage deep learning (DL) reconstruction strategy for AR-PAM to recover high-resolution photoacoustic images at different out-of-focus depths adaptively. The residual U-Net with attention gate was developed to implement the image reconstruction. We carried out phantom and in vivo experiments to optimize the proposed DL network and verify the performance of the proposed reconstruction method. Experimental results demonstrated that our approach extends the depth-of-focus of AR-PAM from 1mm to 3mm under the 4 mJ/cm2 light energy used in the imaging system. In addition, the imaging resolution of the region 2 mm far away from the focus can be improved, similar to the in-focus area. The proposed method effectively improves the imaging ability of AR-PAM and thus could be used in various biomedical studies needing deeper depth.

Drug potency assessment plays a crucial role in cancer chemotherapy. The selection of appropriate chemotherapy drugs can reduce the impact on the patient's physical condition and achieve a better therapeutic effect. Various methods have been used to achieve in vitro drug susceptibility assays, but there are few studies on calculating morphology and texture parameters quantitatively based on phase imaging for drug potency assessment. In this study, digital holography microscopy was used to get phase imaging of ovarian cancer cells after adding three different drugs, namely, Cisplatin, Adriamycin, and 5-fluorouracil. Based on the reconstructed phase imaging, four parameters of ovarian cancer cells changed with time, such as the average height, projected area, cluster shade, and entropy, were calculated. And the half-inhibitory concentration of cells under the effect of different drugs was calculated according to these four parameters. The half-inhibitory concentration, which can directly reflect the drug potency, is associated with the morphological and texture features extracted from phase images by numerical fitting. So, a new method for calculating the half-inhibitory concentration was proposed. The result shows that the morphological and texture feature parameters can be used to evaluate the sensitivity of ovarian cancer cells to different drugs by fitting the half-inhibitory concentration numerically. And the result provides a new idea for drug potency assessment methods before chemotherapy for ovarian cancer.
Transverse spin and the hidden vorticity of propagating light fields

Spatially inhomogeneous fields of electromagnetic guided modes exhibit a complex of extraordinary dynamical properties such as polarization-dependent transverse momentum, helicity-independent transverse spin, spin-associated non-reciprocity and unidirectional propagation, etc. Recently, the remarkable relationship has been established between the spin and propagation features of such fields, expressed through the spin–momentum equations [Proc. Natl. Acad. Sci. USA 118, e2018816118 (2021) PNASA60027-842410.1073/pnas.2018816118] connecting the wave spin with the curl of momentum. Here, the meaning, limitations, and specific forms of this correspondence are further investigated, involving physically transparent and consistent examples of paraxial light fields, plane-wave superpositions, and evanescent waves. The conclusion is inferred that the spin–momentum equation is an attribute of guided waves with a well-defined direction of propagation, and it unites the helicity-independent “extraordinary” transverse spin with the spatially inhomogeneous longitudinal field momentum (energy flow) density. Physical analogies with the layered hydrodynamic flows and possible generalizations for other wave fields are discussed. The results can be useful in optical trapping, manipulation, and data processing techniques.

Recently, high-order topological photonic crystals (PhCs) have attracted huge research attention due to their novel physics mechanism and the application potential in integrated photonics. Based on the two-dimensional Su-Schrieffer-Heeger model, we construct and study the mutual coupling between the high-order corner states in 2D dielectric PhCs. Simulation results show that the Q-factor of such corner-localized quasi-bound states in the continuum (BICs) could be enhanced following mutual coupling in finite size. Furthermore, we study the side-coupled structure based on defect-hybrid waveguides and the edge state microring, the quasi-BIC microcavity. The refractive index sensing application based on corner-localized quasi-BICs shows outstanding simulated sensitivity (312.8 nm/RIU) and figure of merit (∼103 1/RIU). The robustness against fabrication errors due to its topologically protected nature makes it competitive compared with other quasi-BICs sensors.

Reconfigurable linear optical networks are a key component for the development of optical quantum information processing platforms in the NISQ era and beyond. We report the implementation of such a device based on an innovative design that uses the mode mixing of a multimode fiber in combination with the programmable wavefront shaping of a SLM. The capabilities of the platform are explored in the classical regime. For up to 8 inputs and a record number of 38 outputs, we achieve fidelities in excess of 93%, and losses below 6.5dB. The device was built inside a standard server rack to allow for real world use and shows consistent performance for 2x8 circuits over a period of 10 days without re-calibration.
