description: Integrated quantum optics has drastically reduced the size of table-top optical experiments to the chip-scale, allowing for demonstrations of large-scale quantum information processing and quantum simulation. However, despite these advances, practical implementations of quantum photonic circuits remain limited because they consist of large networks of waveguide interferometers that path encode information which do not easily scale. Increasing the dimensionality of current quantum systems using higher degrees of freedom such as transverse spatial field distribution, polarization, time, and frequency to encode more information per carrier will enable scalability by simplifying quantum computational architectures, increasing security and noise tolerance in quantum communication channels, and simulating richer quantum phenomena. Here we demonstrate a scalable platform for photonic quantum information processing using waveguide quantum circuit building blocks based on the transverse spatial mode degree of freedom: mode multiplexers and mode beamsplitters. A multimode waveguide is inherently a densely packed system of spatial and polarization modes that can be coupled by perturbations to the waveguide. We design a multimode waveguide consisting of three spatial modes (per polarization) and a nanoscale grating beamsplitter to show tunable quantum interference between pairs of photons in different transverse spatial modes. We also cascade these structures and demonstrate NOON state interferometry within a multimode waveguide. These devices have potential to perform transformations on more modes and be integrated with existing architectures, providing a scalable path to higher-dimensional Hilbert spaces and entanglement.

description: We study the ground state properties of spin-half bosons subjected to the Rashba spin-orbit coupling in two dimensions. Due to the enhancement of the low energy density of states, it is expected that the effect of interaction becomes more important. After reviewing several possible ideal condensed states, we carry out an exact diagonalization calculation for a cluster of the bosons in the presence of strong spin-orbit coupling on a two-dimensional disk and reveal strong correlations in its ground state. We derive a low-energy effective Hamiltonian to understand how states with strong correlations become energetically more favorable than the ideal condensed states.

description: In this paper, we have studied the dynamical aspects of the cosmological model of the Universe in the Weyl type $f(Q,T)$ gravity, which is an extension of symmetric teleparallel gravity. The non-metricity scalar $Q$ has been expressed in standard Weyl form and can be determined by a vector field $w_μ$ and the trace of energy momentum tensor denoted as $T$. The logarithmic form of the Hubble parametrization has been incorporated and the best fit values of the free parameters have been determined using $32~CC$ sample points, $1701~Pantheon^{+}$ and $6~BAO$ data points. The present value of the $H_{0}\approx 70.2\pm 4.6$, $H_{0}\approx 68.69_{-0.59}^{+0.67}$ and $H_{0}\approx 69.26_{-0.53}^{+0.57}$ respectively for $CC~Sample$, $CC + Pantheon^{+}$ and $CC + Pantheon^{+} + BAO$ datasets. With the constrained values of the free parameters, the cosmographic parameters are constrained and the present value of each parameter has been noted. The deceleration parameter for $CC~Sample$, $CC + Pantheon^{+}$ and $CC + Pantheon^{+} + BAO$ datasets provides $-0.5221$, $-0.5477$ and $-0.5691$ respectively at present time. We have considered exponential and non-linear form of the Weyl type function $f(Q,T)$ to assess the dynamical behaviour of the model. The accelerating cosmological models show the quintessence behaviour at present time as we get the present EoS parameter values obtained as $ω\approx -0.7068$ and $ω\approx -0.6828$ for $CC~Sample$, $ω\approx -0.6991$ and $-0.6949$ for $CC + Pantheon^{+}$ and $ω\approx -0.7001$ and $-0.7084$ for $CC + Pantheon^{+} + BAO$ respectively.

description: As a result of the increased dependency on obtaining information and connecting each computer together for ease of access or communication, organizations risk being attacked and losing private information through breaches or insecure business activities. To help protect organizations and their assets, companies need to develop a strong understanding of the risks imposed on their company and the security solutions designed to prevent or minimize vulnerabilities. To reduce the impact threats have on a network, organizations need to: design a defense layer system that provides multiple instances of protection to prevent unauthorized access to core information, implement a strong network hardware/intrusion prevention system, and create all-inclusive network or security policies that detail user rules and company rights. In order to enhance the overall security of a basic infrastructure, this paper will provide a detailed look into gathering the organizational requirements, designing and implementing a secure physical network layout, and selecting the standards needed to prevent unauthorized access

description: La presente investigación tiene como objetivo Identificar las dificultades en el aprendizaje de la lectoescritura de los niños de cinco años que se encuentran cursando el grado de transición en la Institución Educativa El salvador en Cartagena. Para la recolección de la información se utilizó el test ABC. El cual consta de 8 subpruebas, que miden las habilidades y destrezas psicomotoras y cognitivas para el aprendizaje de la lectoescritura. El estudio es de carácter descriptivo, en el marco de la investigación cuantitativa; porque este enfoque, utiliza preferentemente información cuantificable (medible), ofreciendo una representación matemática del mundo. Los datos que se encontraron con la aplicación del instrumento revelaron que el 23% de los niños evaluados, se ubicaron según el puntaje directo obtenido, en un nivel inferior, es decir que necesitan de asistencia especial para aprender a leer y escribir, mientras que el 69% de participantes según los puntajes se ubicaron en un nivel medio, lo que significa que aprenderán a leer y escribir en un año lectivo; y solo el 8% de los niños obtuvo un puntaje que lo ubico en un nivel superior, es decir que aprenderán a leer y escribir en seis meses. En conclusión, se puede decir que la población evaluada en su mayoría tiene desarrollada una competencia lectora que le permite obtener logros en el periodo de tiempo esperado, dando como resultado un óptimo manejo de esta destreza básica siempre y cuando se utilicen las estrategias adecuadas para ellos en su edad y en su tiempo de madurez.

description: Стаття присвячена питанням ефективності ризик-менеджменту на суб’єктах господарювання. Ефективність функціонування підприємства на ринку визначається тим, наскільки воно досягає поставлених системою управління цілей щодо зниження ризику негативних тенденцій, що впливають на його діяльність і скорочення витрат. Метою даної статті є дослідження ефективності ризик-менеджменту для суб’єктів господарської діяльності та окреслення викликів сьогодення. Визначено сутність систем управління ризиками та сформульовано основні принципи управління ризиками в діяльності суб’єктів господарювання. Проаналізовано сучасні виклики у сфері управління ризиками. У теперішніх умовах, що характеризуються політичною та економічною нестабільністю, діяльність українських підприємств може ускладнюватися різними кризовими ситуаціями, що призводять до неплатоспроможності або банкрутства. Усі кризові явища тісно пов’язані з фінансовими ризиками підприємств, недоліками існуючої системи управління фінансами та відсутністю досвіду управління ризиками. Також проаналізовано розвиток ризик-менеджменту в Україні. Виявлено, що тренд Індустрії 4.0 поширюється в українській економіці. Хоча це є бажаною та очікуваною подією в економіці, учасники господарювання повинні бути готові до ризиків, які можуть стати типовими в майбутньому. А тому, враховуючи важливий характер стратегічного управління, інструменти управління ризиками слід використовувати вже зараз. Встановлено, що ефективність управління ризиками як частини загального менеджменту суб’єкта господарювання визначається його спрямованістю на економічно обґрунтований захист організації від небажаних ситуацій, що призводять до значних втрат і погіршення фінансової рівноваги. Політика управління ризиками є основою стабільного та довгострокового функціонування підприємства. Ідентифікація ризиків, оцінка ризиків (кількісний та якісний аналіз), оптимізація та моніторинг ризиків є складовими ризик-менеджменту. Перспективи подальших досліджень полягають у вивченні та узагальненні закордонного досвіду управління ризиками в діяльності суб’єктів господарювання.

description: While some powerful neural network architectures (e.g., Transformer, Graph Neural Networks) have achieved improved performance in sequential recommendation with high-order item dependency modeling, they may suffer from poor representation capability in label scarcity scenarios. To address the issue of insufficient labels, Contrastive Learning (CL) has attracted much attention in recent methods to perform data augmentation through embedding contrasting for self-supervision. However, due to the hand-crafted property of their contrastive view generation strategies, existing CL-enhanced models i) can hardly yield consistent performance on diverse sequential recommendation tasks; ii) may not be immune to user behavior data noise. In light of this, we propose a simple yet effective Graph Masked AutoEncoder-enhanced sequential Recommender system (MAERec) that adaptively and dynamically distills global item transitional information for self-supervised augmentation. It naturally avoids the above issue of heavy reliance on constructing high-quality embedding contrastive views. Instead, an adaptive data reconstruction paradigm is designed to be integrated with the long-range item dependency modeling, for informative augmentation in sequential recommendation. Extensive experiments demonstrate that our method significantly outperforms state-of-the-art baseline models and can learn more accurate representations against data noise and sparsity. Our implemented model code is available at https://github.com/HKUDS/MAERec.

Improving Performance of IEEE 802.11 by a Dynamic Control Backoff Algorithm Under Unsaturated Traffic Loads

description: The IEEE 802.11 backoff algorithm is very important for controlling system throughput over contentionbased wireless networks. For this reason, there are many studies on wireless network performance focus on developing backoff algorithms. However, most existing models are based on saturated traffic loads, which are not a real representation of actual network conditions. In this paper, a dynamic control backoff time algorithm is proposed to enhance both delay and throughput performance of the IEEE 802.11 distributed coordination function. This algorithm considers the distinction between high and low traffic loads in order to deal with unsaturated traffic load conditions. In particular, the equilibrium point analysis model is used to represent the algorithm under various traffic load conditions. Results of extensive simulation experiments illustrate that the proposed algorithm yields better performance throughput and a better average transmission packet delay than related algorithms.

Precisely, we obtain Hamilton's and Souplet-Zhang's gradient estimates for positive solutions to the nonlinear $f$-heat equation only assuming the Bakry-Émery Ricci tensor is bounded below. As applications, we prove parabolic Liouville properties for some kind of ancient solutions to the nonlinear $f$-heat equation. Some special cases are also discussed.

description: A team of Iranian researchers has developed a computer simulation to measure the performance of hospital emergency departments and determine the best way to allocate their limited medical resources . The emergency department is a primary healthcare unit that treats large numbers of patients. Timely treatment can save lives, but sometimes cannot be delivered owing to a lack of sufficient resources, particularly beds and qualified healthcare professionals. Nezameddin Faghih of the University of Tehran and his colleagues visited the Persian Gulf Hospital in Bushehr, Iran, and used questionnaires and interviews to collect information about three key performance indicators: the use of resources, average patient waiting time, and patient’s total average length of stay in the emergency department. They then used this data to develop a computer simulation model of complex care processes, including triage, diagnosis by general practitioners, and patient flow within the department. The Persian Gulf Hospital is a teaching hospital with 280 beds and an emergency department that is open 24 hours a day, with services on each shift provided by two GPs, one specialist and three nurses, with five other nurses and more specialists on call. Patients’ average length of stay in the emergency department is six hours, due largely to lack of resources and long waiting times. After validating their computer model, the researchers used it to compare different configurations of beds and healthcare staff in order to optimize the allocation of resources and minimize the patients’ length of stay. According to their simulation, the department’s financial budget would allow for a new configuration of 20 inpatient beds, three nurses and one GP, which would reduce patients' average length of stay by nearly 10 minutes. A small increase in the budget would, however, allow for an additional on-site nurse and two GPs, which would lower the length of stay even further. The researchers note that their study was limited by the lack of cooperation from healthcare authorities, difficulties in tracing some of the patients, and lack of relevant information from emergency departments in other hospitals. They believe, however, that their model is an improvement on earlier ones, which did not take length of stay into account, and that hospital managers could use it to evaluate and optimize resources in their emergency departments. 1 “We plan to refine the model by applying new optimization techniques and more data,” says Faghih, “and hope that other hospitals will use the simulation to optimize resource allocation.”

Subjects: Other psychology not elsewhere classified

description: This thesis investigated several factors that have a significant impact on the sleep of adolescents. We found that everyday stress leads to hyperarousal at night and difficulty falling asleep, however, problem-solving during the day may help adolescents mitigate these effects. Planning bedtime on school nights and going to bed as planned helped adolescents have more time in bed, and using several sleep-facilitating behaviours helped adolescents have longer sleep duration and better sleep quality. These sleep self-regulating behaviours can be readily included in sleep interventions to help adolescents improve sleep.

description: Στη συγκεκριμένη εργασία ερευνάται πως επηρεάζει η εργασιακή ικανοποίηση τη διατήρηση θέσεων εργασίας των εργαζόμενων. Η έρευνα πραγματοποιήθηκε με τη βοήθεια ερωτηματολογίων και διανεμήθηκε μέσω του διαδικτύου. Στην έρευνα έλαβαν μέρος 145 συμμετέχοντες, εργαζόμενοι τόσο στον ιδιωτικό όσο και στο δημόσιο τομέα, ενώ για την ανάλυση των αποτελεσμάτων χρησιμοποιήθηκε το στατιστικό πρόγραμμα SPPS. Από τη στατιστική ανάλυση του δείγματος προέκυψε ότι υπάρχει θετική συσχέτιση μεταξύ της εργασιακής ικανοποίησης και της πρόθεσης για παραμονή στην εργασία. Οι πτυχές της εργασιακής ικανοποίησης που μελετήθηκαν όπως οι επόπτες, η προαγωγή, οι παροχές είχαν θετικές συσχετίσεις με την πρόθεση για παραμονή στην εργασία. Η οικονομική κρίση που επικράτησε την τελευταία δεκαετία στην Ελλάδα, καθώς και η εξάπλωση της πανδημίας covid-19 έφεραν αλλαγές στον τρόπο σκέψης και στη νοοτροπία της ελληνικής κοινωνίας. Εξαιτίας αυτών των γεγονότων, επιχειρήσεις και εργαζόμενοι αναζητούν όλο και περισσότερο, ένα σταθερό περιβάλλον δράσης. Από τη μία μεριά οι σύγχρονες επιχειρήσεις έχουν όφελος να δραστηριοποιούνται και να αναπτύσσονται έχοντας στο δυναμικό τους ικανούς και μόνιμους εργαζόμενους με συγκεκριμένο γνωστικό αντικείμενο. Από την άλλη μεριά οι εργαζόμενοι οι οποίοι διατηρούν τη θέση εργασίας τους, αισθάνονται «σιγουριά» τόσο σε επαγγελματικό όσο και σε προσωπικό επίπεδο
description: In this specific work, it is investigated how job satisfaction affects the retention of employees' jobs. The survey was carried out with the help of questionnaires and distributed via the internet. 145 participants took part in the investigation, working in both the private and public sectors, took part in the survey, while the statistical program SPPS was used to analyze the results. From the statistical analysis of the sample, it emerged that there is a positive correlation between job satisfaction and the intention to stay at work. The aspects of job satisfaction studied such as supervisors, promotion, benefits had positive correlations with intention to stay at work. The economic crisis that prevailed in the last decade in Greece, as well as the spread of the covid-19 pandemic brought changes in the way of thinking and in the mentality of Greek society. Because of these facts, businesses and employees are increasingly looking for a stable operating environment. On the other hand, modern businesses have the benefit of being active and developing by having competent and permanent employees with a specific field of knowledge. On the other hand, employees who keep their jobs feel "secure" both professionally and personally

description: The correspondence between local unitary equivalence of bipartite quantum states and simultaneous orthogonal equivalence is thoroughly investigated and strengthened. It is proved that local unitary equivalence can be studied through simultaneous similarity under projective orthogonal transformations, and four parametrization independent algorithms are proposed to judge when two density matrices on $\mathbb C^{d_1}\otimes \mathbb C^{d_2}$ are locally unitary equivalent in connection with trace identities, Weierstrass pencils, Albert determinants and Smith normal forms.

description: Στην παρούσα εργασία, δίνεται βάση στην παρουσίαση του βίου του οσίου Νείλου του Ασκητή, συγκρίνονται οι συναξαριστές μεταξύ τους και διακρίνονται οι σωστές και οι διαστρεβλωμένες πληροφορίες, που με το πέρασμα των αιώνων γνώρισαν πολλές παραλλαγές. Έπειτα στο δεύτερο μέρος επιλέγονται οι δύο λόγοι της φιλοκαλίας για να αναλυθούν και να ερμηνευτούν με βάση την πορεία σκέψης του οσίου και τους πατέρες της Εκκλησίας μας. Σχετικά με το λόγο περί προσευχής , δημιουργείται ένα σχεδιάγραμμα ιδεών και κεφαλαίων με τα πιο βασικά σημεία της κατάστασης της προσευχής , τους κινδύνους που ελλοχεύουν για τον προσευχόμενο και τη θεία βοήθεια που παρέχεται ποικιλοτρόπως από το Θεό στο πλάσμα του. Στη συνέχεια, ακολουθεί ο Λόγος Ασκητικός. Αυτός ο λόγος που αποκρίνεται κατά κύριο λόγο στους αγωνιστές μοναχούς, περιλαμβάνει διακριτικές πνευματικές νουθεσίες για την πορεία της ζωής του μοναχού, τις παγίδες της κοσμικότητας, τις αρετές που αποκτά ο μοναχός, τα χαρακτηριστικά γνωρίσματα των πνευματικών οδηγών. Όλα τα παραπάνω, ο όσιος Νείλος, τα ''βουτά'' μέσα στην, ανωτέρα όλων των φιλοσοφιών, ορθόδοξη χριστιανική φιλοσοφία, η οποία αναδύεται μέσα από την είσοδο και δράση του Χριστού στον κόσμο
description: This dissertation is focused on a presentation of Saint Neilos the Ascetic’s life, a comparison of synaxarists and a distinction between correct and distorted information, which has undergone many variations over the centuries. Then, in the second part, the two discourses of philocaly are selected to be analysed and interpreted on the basis of the course of thought of the Saint and the fathers of our Church. Concerning the discourse on prayer, an outline of ideas and chapters is created with the most essential points of the state of prayer, the dangers that lurk for the pray-er and the divine help variously provided by God to his human creations. The Ascetic Discourse follows. This discourse, which responds primarily to struggling monks, includes subtle spiritual admonitions in the course of the monk's life, the pitfalls of worldliness, the virtues acquired by the monk and the characteristics of spiritual guides. St. Neilos blends all of the above into the supreme of all philosophies, the Orthodox Christian philosophy, which emerges from the arrival and action of Christ in the world

description: A computer program is introduced, which allows to determine statistically optimal approxi-mation using the "Asymptotic Parabola" fit, or, in other words, the spline consisting of polynomials of order 1,2,1, or two lines ("asymptotes") connected with a parabola. The function itself and its derivative is continuous. There are 5 parameters: two points, where a line switches to a parabola and vice versa, the slopes of the line and the curvature of the parabola. Extreme cases are either the parabola without lines (i.e.the parabola of width of the whole interval), or lines without a parabola (zero width of the parabola), or "line+parabola" without a second line. Such an approximation is especially effective for pulsating variables, for which the slopes of the ascending and descending branches are generally different, so the maxima and minima have asymmetric shapes. The method was initially introduced by Marsakova and Andronov (1996OAP.....9..127M) and realized as a computer program written in QBasic under DOS. It was used for dozens of variable stars, particularly, for the catalogs of the individual characteristics of pulsations of the Mira (1998OAP....11...79M) and semi-regular (200OAP....13..116C) pulsating variables. For the eclipsing variables with nearly symmetric shapes of the minima, we use a "symmetric" version of the "Asymptotic parabola". Here we introduce a Windows-based program, which does not have DOS limitation for the memory (number of observations) and screen resolution. The program has an user-friendly interface and is illustrated by an application to the test signal and to the pulsating variable AC Her.

description: The production of hydrogen from water using only a catalyst and solar energy is one of the most challenging and promising outlets for the generation of clean and renewable energy. Semiconductor photocatalysts for solar hydrogen production by water photolysis must employ stable, non-toxic, abundant and inexpensive visible-light absorbers capable of harvesting light photons with adequate potential to reduce water. Here, we show that a-Fe2O3 can meet these requirements by means of using hydrothermally prepared nanorings. These iron oxide nanoring photocatalysts proved capable of producing hydrogen efficiently without application of an external bias. In addition, Co(OH)2 nanoparticles were shown to be efficient co-catalysts on the nanoring surface by improving the efficiency of hydrogen generation. Both nanoparticle-coated and uncoated nanorings displayed superior photocatalytic activity for hydrogen evolution when compared with TiO2 nanoparticles, showing themselves to be promising materials for water-splitting using only solar light.
