Τα αυτόνομα ρομποτικά συστήματα αποτελούν ένα από τα τμήματα που βρίσκονται στην αιχμή της τεχνολογίας και της έρευνας. Τα σύγχρονα ρομποτικά συστήματα που δημιουργούνται δύναται να έχουν την ικανότητα να μπορούν να προσδιορίσουν την θέση τους μέσα στο περιβάλλον το οποίο περιπλανιούνται. Η επίτευξη του συγκεκριμένου στόχου επιτυγχάνεται μέσω της κατασκευής ενός χάρτη την στιγμή που πλοηγείται, μέσω ενός μηχανισμού που είναι ευρέως γνωστός ως ταυτόχρονος προσδιορισμός θέσης και τοποθεσίας (Simultaneous Localization and Mapping –SLAM). Ο χάρτης δημιουργείται μέσω των μετρήσεων που δέχεται το σύστημα από τους επιμέρους αισθητήρες που είναι τοποθετημένοι επάνω στο ρομποτικό σύστημα. Η αύξηση της υπολογιστικής ισχύς τα τελευταία χρόνια και η ευρέως διαδεδομένη χρήση των καμερών οδήγησε στα αυτόνομα συστήματα να επιλέγεται ως κύρια πηγή απόκτησης δεδομένων η χρήση καμερών. Καθώς όμως το ρομπότ διασχίζει την τροχιά του μέσα σε ένα άγνωστο περιβάλλον είναι έντονος ο κίνδυνος δημιουργίας ενός χάρτη με εσφαλμένα στοιχεία στην σχεδιασμένη τροχιά, με κύρια αίτια που μπορεί να σχετίζονται στην κακή εκτίμηση μετρήσεων των αισθητήριων ή σε ενδεχόμενη δυσλειτουργία των ενσωματωμένων οργάνων του συστήματος. Το πρόβλημα που αναφέρθηκε αποτελεί κίνδυνο για την περάτωση της αποστολής του ρομποτικού συστήματος, το οποίο όμως μπορεί να διορθωθεί με επαναπροσδιορισμό της τροχιάς του εφόσον είναι εφικτή η αναγνώριση της περιοχής που διασχίζει μέσω των οπτικών αισθητηρίων που διαθέτει. Τα συστήματα τα οποία βασίζονται αποκλειστικά στις κάμερες ως μέσα αναγνώρισης περιοχής είναι γνωστά ως εμφάνισης βασιζόμενα συστήματα (appearance based systems) και οι τεχνικές που προσπαθούν να λύσουν το πρόβλημα είναι γνωστές ως ανίχνευση κλειστών βρόγχων (loop closure detection). Η παρούσα διδακτορική διατριβή εστιάζει στην δημιουργία ενός αντίστοιχου συστήματος ικανού να αναγνωρίσει μια επαναλαμβανόμενα επισκεπτόμενη περιοχή μέσω των εισερχόμενων εικόνων που δέχεται. Η επίτευξη του συστήματος στηρίζεται σε τρείς σημαντικές μονάδες. Στην αρχή έρχεται η μονάδα επεξεργασίας εικόνας (image processing) με την οποία είναι εφικτή η ερμηνεία των εισερχόμενων εικόνων. Μέσω τεχνικών περιγραφής εικόνας είναι δυνατή η λήψη σημείων ενδιαφέροντος ικανά να περιγράψουν την σκηνή που αντιμετωπίζει το ρομπότ. Κάθε εικόνα ενδέχεται να περιέχει εκατοντάδες τοπικά σημεία ενδιαφέροντος με αποτέλεσμα να μπορεί να περιγραφεί ως ένα σύνολο από επιμέρους χαρακτηριστικά. Ο χάρτης (map) αποτελεί την μονάδα που είναι υπεύθυνη για την αναπαράσταση του κόσμου που γνωρίζει το ρομπότ με βάση τα χαρακτηριστικά που έχουν ληφθεί από τις σκηνές που έχει επισκεφθεί. Τέλος, έρχεται η μονάδα πεποίθησης πιθανής περιοχής (belief generator), η οποία συνδυάζει τα εισερχόμενα δεδομένα με τα δεδομένα του χάρτη ώστε να είναι σε θέση να λάβει την απόφαση για το αν το σύστημα βρίσκεται ή όχι σε οικεία περιοχή με σκοπό να επαναπροσδιορίσει την τροχιά του.
Η διεθνής οικουμενική υπερπολιτεία στη φιλοσοφική σκέψη του Κωνσταντίνου Τσάτσου
Authors: Ξούρα Αθηνά
Published: January 2022

Η πολιτική ενότητα του κόσμου σε μια Διεθνή οικουμενική Υπερπολιτεία είναι η ιδέα του Κωνσταντίνου Τσάτσου για την πορεία όλων των εθνών και όλων των πολιτειών προς έναν τελικώς επιδιωκτέο σκοπό, τον ύπατο σκοπό της ιστορίας όπως ο ίδιος τον ορίζει. Και περιλαμβάνει ο σκοπός αυτός όλες τις αξίες του πολιτισμού θεωρητικές και πρακτικές: την επιστήμη, την τέχνη, την θρησκεία, την ηθική και κοινωνική τάξη και γενικά όλα τα πνευματικά και υλικά επιτεύγματα του ανθρώπου. Ο σκοπός της ιστορίας της ανθρωπότητας είναι ένας. ο ύπατος σκοπός, και επομένως και η κοινωνική τάξη που καθορίζει πώς θα βαδίζουν προς αυτόν τον σκοπό οι ανθρώπινες κοινωνίες πρέπει τελικά να κορυφούται σε ένα ενιαίο σύστημα κανόνων δικαίου. Η Διεθνής οικουμενική Yπερπολιτεία ως το ύπατο δέον αλλά και απόλυτη αναγκαιότητα. του ελεύθερου ανθρώπου έχει ως προϋπόθεση αλλά και παράγωγο την παγκόσμια πολιτειακή τάξη και ειρήνη. Η ιδέα της Υπερπολιτείας, είναι αντίθετη στα σύγχρονα ρεύματα αλλά δεν είναι ούτε ουτοπική, ούτε ανέφικτο όραμα. Ο κόσμος που είναι αποτέλεσμα μέθεξης ύλης και ιδεών μπορεί να οδεύσει προς τον σκοπό αυτό μέσα από την έμπνευση του Μύθου του κάθε λαού, του κάθε έθνους που μπορεί να διαμορφωθεί σε Πολιτεία αξιών και πολιτισμού με την παιδεία και την καλλιέργεια των αξιών, συμβάλλοντας έτσι στην προαγωγή της Διεθνούς Υπερπολιτείας ολόκληρης της ανθρωπότητας. Ο Τσάτσος ορίζει την παιδεία, η οποία κρυσταλλώνεται μέσα στην κοινή παράδοση του κάθε λαού, ως την δύναμη η οποία μπορεί να κατευθύνει τον κάθε άνθρωπο προς τον ύπατο αυτό σκοπό. Ιδιαίτερα το ελληνικό έθνος με την μακραίωνη παράδοση έχει χρέος να αποτελέσει τον μοχλό για την επίτευξη του στόχου αυτού. Αυτό μπορεί να επιτευχθεί με την στροφή προς την ειδική παιδεία της πνευματικής αριστείας η οποία συντελείται με την καλλιέργεια των ανθρωπιστικών αξιών. Ο Τσάτσος διατείνεται ότι μέσα από την καλλιέργεια της ουμανιστικής παιδείας και τη δημιουργία εν πρώτοις των ειδικών σχολείων της πνευματικής αριστείας, όπου θα διδάσκονται οι ανθρωπιστικές αξίες, θα δυναμώσει η πηγή η οποία θα αρδεύσει μετέπειτα με τα ίδια νάματα ολόκληρη την οικουμένη.

Authors: Lekka Fenia , Moustani Dina , Gassias George
Published: January 2022

This article is part of a research project on the transformations that took placebetween 1850 and 1940 in the province of Thessaly, an extensive rural region of the Balkan Peninsula. It focuses on the changes in the economic, social and demographic levels, highlighting the interrelation of these changes in rural Thessaly from the promulgation of the Land Law (1858) under the Ottoman Tanzimat reforms to the annexation of Thessaly and the implementation of extensive land reforms in the 1920s by the Greek state.
Glucose induced ApoB100/ApoAI ratio changes in cultured HepG2 cells in vitro
Authors: Hu Minshan
Published: January 2022

Backgroundː Numerous in vivo human cohort studies have suggested that the apolipoprotein B100/apolipoprotein AI (ApoB100/ApoAI) ratio might be a risk factor in coronary heart disease. The aim of this study was to measure ApoB100/ApoAI ratio changes in cell secretions by incubating HepG2 cells with various amounts of glucose in vitro.

Methods ː HepG2 cells were cultured in low-, normal- or high-glucose Dulbecco's Modified Eagle Medium (DMEM) (1, 4.5 and 10g/L, respectively). Levels of ApoAI and ApoB100 were measured with commercial sandwich enzyme-linked immunosorbent assay kits (cat#: H0123 and H0124) from ShangHai MEIXUAN Biological Science and Technology Ltd (Shanghai, China). Experiments were repeated six times for each assay.

Resultsː The results showed that ApoB100/ApoAI ratio have positive correlations with the glucose concentration increase.

Conclusionsː A higher concentration of glucose induced an undesirable ApoB100/ApoAI ratio change, which suggests a new regulatory pathway in lipoprotein catabolism and provides a cell model for further mechanism study. This finding may lead to novel therapeutic ways for diagnosis and treatment for coronary artery disease.

Authors: Purnama Muhammad Thohawi Elziyad , Hendrawan Dodit , Wicaksono Arya Pradana , Fikri Faisal , Purnomo Agus , Chhetri Shekhar
Published: January 2022

Background: Horses are herd animals that have been domesticated in the last century. In several countries, an overview of risk factors and clinical evaluation in horses with colic has not been well‐described. This study aimed to evaluate risk factors and hematological profiles in horses associated with colic in Gresik, East Java, Indonesia.

Methods: A cross-sectional study was performed during April - October 2019. A total of 115 horses were diagnosed based on physical examination, clinical symptoms, and rectal examination. A questionnaire was asked to the horse-owners to analyze the risk factors while the clinical examination was performed and blood samples were collected for pre-treatment and 14 days post-treatment. Hematological profile was evaluated from a whole blood sample. Serum cortisol, plasma epinephrine, and norepinephrine concentrations were also evaluated after separating the aliquots. 

Results: Of the 115 horses, 96 were diagnosed with colic. The horses with colic showed a significant association between cases with gender (p<0.021), breed (p<0.000), wheat bran feeding (p<0.015), concentrate feeding (p<0.003), anthelmintics administration (p<0.000), gastrointestinal parasites (p<0.000), dental diseases (p<0.024), previous exposure to colic (p<0.000), body condition score (p<0.000), and access to water per day (p<0.000). Based on whole blood and serum evaluation, there were ameliorated significantly on the hematological profile (p<0.01), serum cortisol (p<0.05), and plasma epinephrine (p<0.01) at 14 days post-treatment.

Conclusion: This study has identified factors associated with colic in Delman horses. The study provides crucial information to investigate cases of colic and to contribute the development of healthcare strategies during treatment and clinical evaluation.

A 57-year-old male who had been working in masonry for 33 years was hospitalized for renal function decline associated with exertional dyspnea. He presented with hypertension and limb edema. Urinalysis revealed an active urine sediment with glomerular proteinuria at 1.5 g/24h and the renal biopsy identified mesangial IgA Nephropathy. Chest tomography scans showed signs of silicosis. The patient received Angiotensin-Converting Enzyme Inhibitors with stable renal function. To our knowledge, the association of silicosis-IgA nephropathy has rarely been reported in the literature. This case highlights the effect of chronic exposure to silica dust and its association with both silica and renal disease.
Comparison of accidental pediatric scald burns in a tertiary care center: hot cauldron burns versus accidental spill burns
Authors: Nakarmi Kiran Kishor , Pathak Bishnu Deep , Shrestha Dhan , Budhathoki Pravash , Rai Shankar Man
Published: January 2022

Background: Scald burns result from exposure to high-temperature fluids and are more common in the pediatric age group. They occur mainly by two mechanisms: (i) spill and (ii) immersion (hot cauldron) burns. These two patterns differ in clinical characteristics and outcomes. Scalds cause significant morbidity and mortality in children. The objective of this study was to compare accidental spill burns and hot cauldron burns in a hospital setting.

Methods: An analytical cross-sectional study was conducted by reviewing the secondary data of scald cases admitted during the years 2019 and 2020 in a burn-dedicated tertiary care center. Total population sampling was adopted. Data analysis was done partly using SPSS, version-23, and Stata-15. Mann Whitney U-test and Chi-square/Fisher's exact test were done appropriately to find associations between different variables. Binary regression analysis was performed taking mortality events as the outcome of interest.

Results: Out of 108 scald cases, 43 (39.8%) had hot cauldron burns and 65 (60.2%) had accidental spill burns. Overall mortality was 16 (14.8%), out of which hot cauldron burns and accidental spill burns comprised 12 (75.0%) and 4 (25.0%), respectively. Binary logistic regression analysis showed the type of scald, age, and Baux score found to be associated with mortality. Every one-year increment in age had a 29% lower odds of occurrence of mortality event (adjusted odds ratio [OR], 0.71; 95% confidence interval [CI], 0.50-0.99, p=0.042). Likewise, every one-point increment in Baux score was associated with 19% higher odds of mortality (adjusted OR, 1.190; 95% CI, 1.08-1.32; p<0.001).

Conclusions: Accidental spill burn was more common but mortality was significantly higher for hot cauldron burns. The risk of mortality was significantly higher in burn events occurring outside the house, and burns involving back, buttocks, perineum, and lower extremities.

Authors: Noronha Jean , Samuel Stephen , Singh Vijay Pratap , Prabhu H Shivananda
Published: January 2022

Background: Prehabilitation is a therapeutic strategy involving preoperative physical exercises, nutritional support, and stress and anxiety reduction. This approach has been gaining popularity and has been seeing effective results in adults in terms of improving pre and postoperative outcomes. The purpose of this review was to summarise the evidence about the effects of exercise-based prehabilitation programs on various outcome measures in children post elective surgeries.­­

Methods: PubMed, Scopus, Web of Science, PEDro, CINAHL/EBSCO and EMBASE electronic databases were searched from inception to June 2021. Based on the inclusion criteria, titles and abstracts were independently screened by the authors. After that, a data extraction table of the selected studies which included the participants, type, and details of exercise intervention, outcome measures and results were analysed after which the quality assessment of the studies was done.

Results: The search yielded 2219 articles of which three articles fulfilled the inclusion criteria with two studies being randomized controlled trials and one being a quasi-experimental pre-post type of study. One randomized controlled trial was on the effects of exercise-based prehabilitation in reducing pulmonary complications post cardiac surgeries in children and the other two studies were on the effects of prehabilitation on functional capacity & pulmonary function. All the three articles found that exercise-based prehabilitation had a positive effect on children’s post-surgery.

Conclusion: Although there is a paucity of evidence-based literature, we conclude based on the existing literature retrieved by our review that exercise-based prehabilitation improves postoperative outcomes and helps in reducing postoperative complications in children undergoing various surgeries.
«Revolutionary» Trends in the Labor Market

Published: January 2022

The labor market in our time is experiencing revolutionary changes. The era of a relatively stable labor market is over. There is no balance of vacancies between the needs of the modern economy and specialists trained by the education system. New technologies lead to the emergence of new professions, new vacancies. And hence the main and paradoxical trend of the modern labor market of new technologies - a lot of “non-specialists” (that is, people who have not received a special education) who create new types of labor activity, and then new professions appear, and as a result, new vacancies, and, again, new "non-specialists" creating new specialties. From the point of view of the structure of modern education, it is ready to solve these problems. But, unfortunately, these education functions are not yet activated. And the labor market needs them more and more. Those. education should teach students to self-seek.

Pozwala kształtować własny światopogląd, odnawiać kontakty z bliskimi oraz prawidłowo adaptować się do wymogów i warunków życia.
To Engage or Not to Engage with AI for Critical Judgments: How Professionals Deal with Opacity When Using AI for Medical Diagnosis
Authors: Lebovitz Sarah , Lifshitz-Assaf Hila , Levina Natalia
Published: January 2022

Artificial intelligence (AI) technologies promise to transform how professionals conduct knowledge work by augmenting their capabilities for making professional judgments. We know little, however, about how human-AI augmentation takes place in practice. Yet, gaining this understanding is particularly important when professionals use AI tools to form judgments on critical decisions. We conducted an in-depth field study in a major U.S. hospital where AI tools were used in three departments by diagnostic radiologists making breast cancer, lung cancer, and bone age determinations. The study illustrates the hindering effects of opacity that professionals experienced when using AI tools and explores how these professionals grappled with it in practice. In all three departments, this opacity resulted in professionals experiencing increased uncertainty because AI tool results often diverged from their initial judgment without providing underlying reasoning. Only in one department (of the three) did professionals consistently incorporate AI results into their final judgments, achieving what we call engaged augmentation. These professionals invested in AI interrogation practices—practices enacted by human experts to relate their own knowledge claims to AI knowledge claims. Professionals in the other two departments did not enact such practices and did not incorporate AI inputs into their final decisions, which we call unengaged “augmentation.” Our study unpacks the challenges involved in augmenting professional judgment with powerful, yet opaque, technologies and contributes to literature on AI adoption in knowledge work.

This report describes a five-year-old dog who had been bitten by a Russell’s viper. The patient presented clinical signs of anorexia, vomiting, lethargy, and anuria. Collectively with the laboratory test results of azotemia and hyperkalemia, acute kidney injury was diagnosed. Peritoneal dialysis (PD) was instigated when the azotemia became worse and anuria persisted, despite aggressive medical and fluid therapy. After 14 days of PD, the anuria was resolved, and the patient was discharged 7 days later. At the end of the last dialysis cycle, there was a significant reduction in the severity of the azotemia, and the serum hyperkalemia had returned to normal. One month after PD, the patient no longer had any abnormal clinical signs. Both the patient’s serum blood urea nitrogen level and creatinine levels returned to within the normal limit. PD proved to be an effective management of acute kidney injury in Russell’s viper envenomation in the reported dog. This report also describes a detailed procedure of PD which can be instigated in any veterinary practice

Fly is one of the vectors of foodborne pathogenic vectors and causes myiasis in humans and animals. To prevent the contamination of food and myiasis, various chemical products are commonly used. However, eco-friendly is now a trend all over the world so natural products are the alternative ways to reduce the chemical residue in the environment. The present study was screened the 12 natural products in 4 groups; the essential oil plants, the alkaloid plants, the cyanogenic plant, and the inorganic compounds which use a simple extraction on the fly repelling and larvicide. The fly repelling efficacy with 2 criteria consist of the time of the first swarm and percent repelling (PR) in the first 15 min. The larvicidal efficacy was determined by the mortality rate within 24 h. The Kaffir lime peels aqueous crude extract exhibited the best result on fly repelling from both criteria with no significant difference. The bamboo shoots aqueous crude extract gave the best result on larvicide with significantly different from other groups (P < 0.001) which was faster than the positive control group (Coumaphos & Propoxur). Moreover, the high mortality rate reached 73.33 ± 15.28% within 24 h, higher than the positive control group. The present study indicates the power of common natural products on fly repellent and larvicide that may apply for fly repellant to reduce the food contamination especially fresh materials and prevention or treatment of animal and human myiasis in rural areas

This study was designed (1) to examine the relationship between ovary sides/sizes after superstimulation treatment and ovulatory responses in terms of large follicles, corpora lutea (CLs) numbers, and ovulation rate; and (2) to evaluate the coefficient of determination (R2) as a tool to predict the subsequent superovulatory responses by ovary sizes after superstimulation treatment in the Thai-Holstein crossbreed dairy cows. Data included 33 records from 12 superovulated Thai Holstein crossbreds. Cows were estrus synchronized on day 0 and superstimulated with 400 mg of FSH with decreasing doses twice daily for 4 days. After superovulatory treatment (day 9), the sizes of ovaries were measured and divided into 3 groups by quarters according to the ovarian sizes. Group A (< 816 mm2) ovaries were 25% smaller and group C (> 1449 mm2) ovaries were 25% larger than group B ovaries (816–1449 mm2). On day 9 and 16, there were no significant differences in the average ovary area (p > 0.05). The numbers of large follicles and CLs of group B and C were greater than those of group A (p < 0.05). The ovulation rate did not differ among groups (p > 0.05). The moderate R2 score between ovary size after superovulatory treatment and the numbers of dominant follicles and CLs were calculated (R2 = 0.445 and 0.370, p <0.05) while the beta coefficient (b-value) was positive for both observation parameters. In conclusion, the numbers of large follicles and CLs related to the size of ovaries after superovulation treatment. The moderate R2 score obtained in this study could be indicative of the limited possibility for using ovary size after superovulatory treatment for predicting superovulatory responses
Monitoring of reproductive health in the striped catfish Pangasianodon hypophthalmus (Sauvage, 1878) from the Saen Saep Canal, Thailand

Khlong Saen Saep is one of the most important and large canal systems in Bangkok, Thailand. However, the emergence of heavily polluted water has occasionally been reported due to the domestic sewage and industrial effluents discharged into the system. This situation may affect the reproductive status of aquatic lives residing in this canal. To evaluate the reproductive status of the canal inhabitant, the striped catfish Pangasianodon hypophthalmus (Sauvage, 1878)—a common dweller of the Saen Saep Canal—was collected from two selected stations, the Bumpen Nua Temple and the Kamalun Islam Mosque. The fish gonads were then anatomically and histologically examined. The results indicated that neither parasites nor ovary with external abnormality were found. Nevertheless, several histological alterations were detected, including vacuolar degeneration of previtellogenic oocytes, accumulation of melanomacrophage centers (MMCs), and atretic oocytes. Moreover, severe histopathological changes, such as the eosinophilic cytoplasm of spermatogonia, MMCs, blood congestion, and syncytium of spermatozoa, were observed in the fish testis. Our study suggested that the environmental stress and pollutions previously reported from the Saen Saep Canal possibly underpin the gonadal impairments of P. hypophthalmus examined and may have adverse impact on the reproductive health of others living in this canal system
Dry Bean (Phaseolus vulgaris L.) Crop Water Production Functions and Yield Response Factors in an Arid to Semi-Arid Climate
Authors: Sharma Vivek , Rai Abhijit
Published: January 2022

Highlights

Deficit irrigation negatively affected dry bean yield and yield components.

Excess irrigation increased crop ETc but not dry bean yield.

Soil moisture fluctuation was greater in the top 0.3 m of the soil profile compared to deeper depths.

Crop water production function had a slope of 18.9 kg ha-1 mm-1 and threshold crop evapotranspiration of 171 mm.

Dry bean crop was found to be sensitive to water stress (yield response factor Ky = 1.94).

Abstract. Under changing climate conditions and declining water resources, understanding crop response to water stress is critical for effective irrigation management. The objectives of this study were to quantify dry bean (Phaseolus vulgaris L., cv. Othello) soil moisture dynamics, crop evapotranspiration (ETc), and yield response factor and to develop dry bean irrigation and crop water production functions (IWPF and CWPF). Five irrigation treatments, i.e., full irrigation (FIT), 75% FIT, 50% FIT, 25% FIT, and 125% FIT, were evaluated using a randomized complete block design (RCBD) with three replications for three years (2017, 2018, and 2019) in the arid to semi-arid intermountain region of Powell, Wyoming. The results showed a significant influence of irrigation on dry bean soil moisture dynamics and ETc. The dry bean crop showed a greater soil moisture fluctuation in the top 0.3 m of the soil profile compared to 0.6 m and at 0.9 m. ETc ranged from 187 to 438 mm, from 190 to 409 mm, and from 217 to 398 mm in the 2017, 2018, and 2019 growing seasons, respectively. A positive two-segment relationship was observed between dry bean seed yield and cumulative irrigation water applied. The average cumulative seasonal irrigation of 310 mm resulted in maximum seed yield. For all three years, the seed yield increased linearly with ETc. Combining the data from the three years resulted in a CWPF with a slope of 18.9 kg ha-1 mm-1 and an offset of 171 mm of ETc (i.e., the ETc required for crop establishment before any seed yield is produced, or threshold ETc). Moreover, the dry bean crop was found to be sensitive to water stress (Ky = 1.94). These results indicated that under the typical semi-arid to arid climate conditions of the intermountain region of Wyoming, deficit irrigation of dry bean may not be a viable strategy because the yield loss outweighs water-saving benefits.

Making interpretive policy analysis critical and societally relevant: emotions, ethnography and language
Authors: Durnová Anna
Published: January 2022

This article summarises the main achievements of interpretive approaches to policy analysis and signposts ways to develop them to strengthen inclusivity and diversity. By visualising tangible strategies used in the approach, it demonstrates how we can better understand how policies are made and understood. At the same time, the article places a strong focus on emotions and ethnography as a way to strengthen the societal relevance of the approach. Focusing on emotions in policy research goes beyond a simple interest in emotions, using them as a specific critical lens to view the researched phenomenon while considering how policy ideas are framed as relevant or irrelevant through expressive language. Analogously, the article describes ethnography as an epistemological lens for analysing policy wherein researchers embrace human bias and the normativity of their research. To illustrate how these two lenses work in practice, the article concludes by discussing the research design of an analysis of the role of fathers in the policy debate around birth care in Czechia.
Challenging boundaries to expand frontiers in gender and policy studies
Authors: Lombardo Emanuela , Meier Petra
Published: January 2022

Gender and policy studies needs to face challenges and cross boundaries if the discipline is to develop. This article argues that gender and policy studies needs to explicitly foreground the centrality of politics – the analysis of power – in approaching policy. The discipline confronts boundaries in relation to inclusivity, diversity and relevance. Inclusive gender equality demands challenging the hegemonising and marginalising boundaries in the field, which contributes to its relevance by placing politics and power centre stage. Openness to the diversity of gender and policy approaches, a more systematic and thoughtful application of intersectionality, cooperation with LGBTQI+, critical race studies and normative political theory provide opportunities to challenge boundaries and advance knowledge. We argue that explicit reflexivity about power dynamics and knowledge production, employing a plurality of approaches, will better equip the discipline to navigate major challenges and crises, and offer more nuanced democratic and egalitarian societal contributions.
Conceptualising policy design in the policy process
Authors: Siddiki Saba , Curley Cali
Published: January 2022

The study of policy design has been of long-standing interest to policy scholars. Recent surveys of policy design scholarship acknowledge two main pathways along which it has developed; one in which the process of policy designing is emphasised and one in which the output of this policy designing process – for example, policy content – is emphasised. As part of a survey of extant research, this article discusses how scholars guided by different orientations to studying policy design are addressing and measuring common policy design concepts and themes, and offers future research opportunities. The article also provides a platform for considering how insights stemming from different orientations of policy design research can be integrated and mapped within the broader public policy process. Finally, the article raises the question of whether a framework that links different conceptualisations of policy design within the policy process might help to advance the field.

Published: January 2022

In the integrated navigation system, which consists of a laser Doppler velocimeter (LDV) and strapdown inertial navigation system, it is necessary to calibrate the LDV. We propose an online calibration method for a LDV based on the strapdown inertial navigation system. This system uses highly accurate output information in the early stage of the inertial navigation system to carry out coarse calibration for the velocimeter and then employs a Kalman filter to correct the results of coarse calibration to achieve high precision calibration for the velocimeter. Experimental results show that the relative distance error of dead reckoning is less than 0.02%, indicating that the proposed online calibration method can achieve high-precision calibration for the velocimeter.
Fabrication and analysis of enhanced thermal stability and high-sensitivity turnaround point long-period fiber grating

Published: January 2022

This paper presents a what we believe is a novel method to fabricate turnaround point
long-period gratings (TAP-LPGs) possessing enhanced thermal stability
and high sensitivity. It is shown by analysis and by experiment that
LPG resonance in photosensitive fibers can be controlled partially by
UV fluence and thermal annealing. TAP-LPGs with enhanced thermal
stability were fabricated by following three steps: (I) finding
grating period versus writing UV fluence for TAP operation; (II)
writing gratings at a relatively higher period with higher fluence, in
which case the resonance is out of phase; (III) controlled annealing
so that the postannealed LPG operates at/near TAP. The thermal
stability is enhanced. The average temperature sensitivity of dual
peak resonance measured for a typical TAP-LPG in the temperature
interval of 70°C–240°C is about 2.3 nm/°C. This study will be useful
for the development of high temperature TAP-LPG sensors.

Authors: Rafel Albert , Maes Jochen
Published: January 2022

Mobile network operators are facing the rollout of 5G New Radio small cells in the next few years. High cell density will require intensive support of optical transport, and there are multiple options depending on cell configuration and capacity. Comparing these optical technologies in terms of capacity and cost is important to maximize return on the likely limited deployment budget. We developed a model that can be used by operators in the strategy and decision-making phase and present example results on outdoor 5G small cells using the sub-6-GHz spectrum bands.
Information structure and general characterization of Mueller matrices
Authors: Gil José J. , San José Ignacio
Published: January 2022

Linear polarimetric transformations of light polarization states by the action of material media are fully characterized by corresponding Mueller matrices, which contain, in an implicit and intricate manner, all measurable information on such transformations. The general characterization of Mueller matrices relies on the positive semi-definiteness of the associated coherency matrix, which can be mathematically formulated through the nonnegativity of its eigenvalues. The enormously involved explicit algebraic form of such formulation prevents its interpretation in terms of simple physical conditions. In this work, a general and simple characterization of Mueller matrices, based on their statistical structure, is presented. The concepts associated with the retardance, enpolarization, and depolarization properties as well as the essential coupling between the latter two are straightforwardly described in the light of the new approach.
Spectral phase-front diagnostics for ultrashort laser pulses via quasi-self-referenced interferometry
Authors: Poplavski Sergej , Hagmeister Bastian , Tesch Sebastian , Pretzler Georg
Published: January 2022

We present a novel, to the best of our knowledge, design for the spectrally resolved wavefront diagnostics of ultrashort laser pulses. The design uses quasi-self-referenced interferometry (qSRI), is completely achromatic, and avoids dispersion. The qSRI utilizes a perfect reference beam enabling an absolute measurement of the near-field spatial phase distributions for the different spectral components of ultrashort laser pulses. For this, a Mach–Zehnder geometry is coupled with a spatial filter. Combining the qSRI with a reflective grating allows for the measurement of phase fronts in the whole spectrum of a broadband laser pulse without any calibration.
Characterization of two-color ultrashort laser pulses using polarization-gating and transient-grating frequency-resolved optical gating

Published: January 2022

Two-color ultrashort laser pulses have emerging applications in
numerous areas of science and technology. In many cases, the slightest
change in the combined electric field of a two-color pulse greatly
affects its interaction mechanism with the system. Therefore, a
precise characterization of the temporal/spectral profile of the
combined electric field is of great importance. In this work, we
demonstrate that a full characterization is possible using the
well-known transient-grating (TG) or polarization-gating (PG)
frequency-resolved optical gating (FROG) techniques, and by employing
the recently developed Retrieved-Amplitude N-grid Algorithmic (RANA)
approach for the retrieval process. We demonstrate the validity of
using these techniques and this approach for multi-cycle and few-cycle
pulses in the absence and presence of noise.
Dependence of the probability density function of laser radiation power on the scintillation index and the size of a receiver aperture

Published: January 2022

Power scintillations of a Gaussian laser beam propagated through a 7 km long horizontal atmospheric path for a wide range of turbulence strengths and different sizes of the receiver aperture were studied experimentally. The probability density function (PDF) and its properties were analyzed for a wide range of scintillation conditions. It was shown that the PDF can be described by the fractional exponential distribution in the strong scintillation regime (scintillation index of power measured on aperture

In the strong scintillation regime, the aperture averaging effect resulted in the transition from the fractional exponential distribution to the fractional gamma (FG) distribution when the aperture diameter is about the size of the isoplanatic region (d/a∼1). The FG distribution better approximates the experimental PDF because it accounts for the fact that the probability of zero power values becomes zero due to the averaging effect of the aperture. The fractional gamma distribution is the best approximation of the PDF for a finite aperture when

Detecting multiple chiral centers in chiral molecules with high harmonic generation
Authors: Neufeld Ofer , Wengrowicz Omri , Peleg Or , Rubio Angel , Cohen Oren
Published: January 2022

Characterizing chiral is highly important for applications in the pharmaceutical industry, as well as in the study of dynamical chemical and biological systems. However, this task has remained challenging, especially due to the ongoing increasing complexity and size of the molecular structure of drugs and active compounds. In particular, large molecules with many active chiral centers are today ubiquitous, but remain difficult to structurally analyze due to their high number of stereoisomers. Here we theoretically explore the sensitivity of high harmonic generation (HHG) to the chiral of molecules with a varying number of active chiral centers. We find that HHG driven by bi-chromatic non-collinear lasers is a sensitive probe for the stereo-configuration of a chiral molecule. We first show through calculations (from benchmark chiral molecules with up to three chiral centers) that the HHG spectrum is imprinted with information about the handedness of each chiral center in the driven molecule. Next, we show that using both classical- and deep-learning-based reconstruction algorithms, the composition of an unknown mixture of stereoisomers can be reconstructed with high fidelity by a single-shot HHG measurement. Our work illustrates how the combination of non-linear optics and machine learning might open routes for ultra-sensitive sensing in chiral systems.
Experimental research on a multi-aperture phase modulation technique based on a corner-cube reflector array

Published: January 2022

In this paper, a novel phase modulation technique based on a corner-cube reflector (CCR) array is proposed and demonstrated experimentally. The piezoceramics are linked behind each CCR. When the beams irradiate on the CCR array, the phase modulation can be realized by applying a voltage to piezoceramics to control the spatial location of each CCR. The piston phase errors of the device itself are compensated by employing the stochastic parallel gradient descent (SPGD) algorithm. Then, the piezoceramics are loaded with preset voltages to obtain the expected phase, and the anticipative optical field is generated. In the experiment, the piston phase errors of the 7-way and 19-way CCR array are corrected well. In order to further verify the phase control capability of the device, a vortex beam carrying orbital angular momentum (OAM) of 1 is generated by utilizing the 6-way CCR array. The experimental results confirm the feasibility of the concept.
Multi-tasking geometric phase element array based self-referenced vortex interferometer for three-dimensional topography
Authors: Zhang Jinrun , Fan Fan , Fu Wenxin , Zeng Jinwei , Wang Jian
Published: January 2022

Interferometry is a basic physical method to record and reconstruct the three-dimensional (3D) topography of a complex object. However, mainstream interferometers using two beams can be unstable in a volatile environment. Here, we present a self-referenced optical vortex interferometer employing multi-tasking geometric phase elements. Compared with conventional devices, the multitasking elements can enable vortex filters while deflecting the interference beams to achieve high mode purity in broadband. We use the proposed system to reconstruct the 3D topography of a sample while determining its surface elevations and depressions accurately and conveniently in one static interference pattern.
