Authors: Li Juan
Published: February 2024

In this paper, the MEA algorithm is applied to the initial optimization of the weight threshold of BP neural network, which improves the stability of the classification of course resources through a two-stage optimization search process. Secondly, the effective recognition of knowledge point entities of teaching resources is realized by combining the LSTM-CRF entity recognition model, the BERT pre-trained language model and the text data enhancement technique based on the maximum bi-directional matching algorithm. In addition, the article proposes a candidate knowledge point entity generation method based on Levenshtein Distance and an entity characterization method based on BERT-TextCNN, which helps to alleviate the noise problem of the text data of curriculum resources and enhance the entity linking effect. The results of the study show that this newly constructed online course resource repository can significantly improve the allocation level of educational resources and reduce the variability of resource allocation among colleges and universities. The coefficient of educational resource allocation variation for SN217 in the university district was reduced from 0.764 to 0.518.In addition, the mean values of this repository in terms of learning path, perceived usefulness, course resources, and intention to use ranged from 1.45 to 1.66.The study in this paper provides valuable methods and insights for optimizing online educational resources.

Published: February 2024

As the world goes digital, many companies have found that their performance improves when they digitize their operations. This is especially true in light of the COVID-19 pandemic, as companies must rely more on digital tools to survive. Our paper aims to examine the connection between digital competitiveness and the financial performance of 86 digital businesses at the country level before, during, and after the COVID-19 pandemic over the period 2017--2021. Unlike previous findings that relied on qualitative methods, our research relies on quantitative methods. More precisely, we empirically examine the impact of digital competitiveness (i.e., an index) on financial performance (i.e., measured by return on assets) through linear regression models and panel data regressions for three specific periods (2017-2019 pre-pandemic, 2020 pandemic, and 2021 post-pandemic). We found that COVID-19 allows firms to adopt digitalization. More specifically, comparing the three periods, we discovered that digital competitiveness positively influences business financial performance in the post-Covid era. Looking ahead to the post-Covid world, it is clear that companies must prioritize digital competitiveness to ensure their long-term success. Governments can learn important lessons from this research on how to help companies digitize."

Commingled remains analysis is a fundamental problem in bioarchaeology and forensic anthropology. In cases of commingling, the bones of all individuals represented must be accurately and reliably differentiated. X-ray fluorescence spectrometry (XRF) can identify species and individuals when bone fragments are found in archaeological or forensic contexts. The present study aimed to verify whether portable X-ray fluorescence spectrometry (pXRF) can be used to differentiate bone fragments at the species level (Bos taurus, Sus domesticus, Equus caballus, and Homo sapiens) and at the individual level of human individuals. We also aimed to verify whether species and individuals can be differentiated using pXRF even if the bones were burned. A total of 119 adult human bones from archaeological sites in Central Moravia and Silesia and 17 adult non-human bones from archaeological sites in Central Moravia (Czech Republic) were examined. All bones are dated to various periods (from the Bronze Age to Modern Times). When differentiating the unburnt and burnt bones at the species level, the overall accuracy of classification was 84.6% and 93.9%, respectively. When differentiating unburnt human bones at the individual level, the correct classification ranged from 88.1% to 72.7%. The differentiation of the burnt bones of humans at the individual level achieved an average success rate of more than 60%. The results confirmed that pXRF can be used for species and individual differentiation of unburnt bones and is almost equally applicable to burnt bones.

This study reports the first comprehensive data on the dietary aspects of Gauja Livs in the 11th–12th century CE. This region is presently lacking in bioarchaeological material (human bones and ancient plant remains), which is typically used for decoding the ancient diet. To tackle this problem pottery fragments from Turaida hillfort and Pūteļi cemetery were studied using Lipid Residue Analysis. Samples included both pottery clay matrix and burnt foodcrusts. The main goal of the study was to obtain direct information on the food substances consumed by the Gauja Livs, based on the pottery material from Turaida hillfort and from the local cemetery to reassess existing assumptions about their dietary practices both in mundane and ritual contexts. The lipid residue results revealed the main food groups consumed by the community contained terrestrial animal and aquatic products, but also provided insights into a potential mixing of different foodstuffs. Some of the expected foodstuffs were not found in or on the analysed pottery, leaving the possibility for a hypothetical use of cooking practices that might have excluded ceramic vessels. This research also gives preliminary indications of gender-based dietary patterns if assessed in context with other studies from the eastern Baltic Sea region in the pre-medieval and early medieval period.

Introduction. Humanity faced the same enemy, the new SARS-CoV-2 coronavirus, and so the COVID-19 pandemic has become a common phenomenon faced by the modern world in the era of globalization. This has also proven to be a particular challenge for gynecologists. Aim. To demonstrate that in gynecology as a science about women, also in the context of the COVID-19 pandemic, a holistic approach to women’s care is important, and this care should include health-promoting activities, including sexual health. Material and methods. Analysis of the literature related to the problem of the COVID-19 pandemic, sexual health of women, as well as clinical observations from gynecological practice during the pre-vaccination pandemic period, which concerned the intensity of menstrual pain compared to the pre-pandemic period in 58 young, healthy women. The VAS scale was used. Results. There was a significant difference in the level of pain intensity in women before the pandemic and during the pandemic in 2020 (p < 0.0001). Before the pandemic, women felt less pain than during the pandemic. Conclusions. Clinical observations indicate that the stress associated with the pandemic and the restriction of movement related to lockdown during the pandemic may be associated with an increase in menstrual pain. Also in gynecological practice, the influence of bad experiences, suffering and pain related to the pandemic on the general condition, psyche, partnerships and functioning in the sexual sphere is observed.

Authors: Obcowska-Hamerska Aneta , Basaj Jarosław
Published: February 2024

The paper discusses the most common bacterial sexually transmitted infections (STIs) causing anorectal symptoms. Despite their high prevalence, the surgeons’ awareness of this group of disorders, trends in sexual behaviours and the epidemiology of sexually transmitted infections is still limited. We discussed the most common infections, i.e. gonorrhoea, chlamydia and syphilis, in this paper. Bacterial pathogens responsible for inflammation of the rectum and anal canal may also include Mycoplasma genitalium, Escherichia coli, Salmonella, Campylobacter, and Shigella. In the case of a patient with suspected sexually transmitted infection, in addition to theoretical knowledge, a conversation about the patient’s sexual history and preferences, the risk of HIV infection and the reasons for performing diagnosis for sexually transmitted infections under intimate conditions is also important. Sexually transmitted infections may also have a viral aetiology, which will be discussed in the second part of the paper.

Biodentine is a calcium-silica cement with biocompatible and bioactive properties. It can replace both crown and root dentine while preserving the vital pulp. The study contains indications of use, prognosis, clinical observations and in vitro tests of the physical properties of Biodentine. The PubMed database was reviewed in the period 2006-2020. The search criteria were: “Biodentine”, “MTA”, “permanent immature tooth”, “revascularization”, “resorption”, “dental trauma”. The literature available in the text databases of the Jagiellonian University library was used. 73 Polish and foreign items were selected. Biodentine is a material widely used in various fields of dentistry. Long-term prognosis depends on many factors (including proper qualification for the procedure, technique of the procedure, sterility of the operating field, tightness of the filling). Based on the data from the literature, Biodentine was compared to MTA. This comparison made it possible to conclude that both Biodentine and MTA are of equal use. Choice between Biodentine or MTA should be based on individual aspects of each clinical case and the experience (preferences) of the clinician. The literature most often presents short-term observations (up to 3 years) and descriptions of individual cases. However, a large number of publications on this subject from various research centers allows for the collection of their results and to take a deeper look at the selection of biodentin and its effects.

Published: February 2024

PFAPA syndrome is an autoinflammatory disease that belongs to the group of periodic fever syndromes in children. It is a rare, polygenic disease that has a tendency to self-limit with age and disappear before adulthood. The most important symptoms of PFAPA are: periodic fever, aphthous stomatitis, pharyngitis, and cervical lymphadenopathy. Insufficient knowledge about the causes of the disease does not yet allow for the use of causal treatment. Pharmacotherapy (ibuprofen, glicocorticosteroids) is used during relapses to reduce symptoms, but it does not prevent systematic relapses. When necessary, tosillectomy allows for complete remission of the disease.

Published: February 2024

There are a large number of potential schedulable resources in the integrated energy system of electricity, heat, cold, and gas. However, most of these energy sources are currently operated separately, with low system flexibility, low energy utilization rate, and serious abandonment of wind and solar energy. In order to improve the flexibility of integrated energy systems and the capacity of renewable energy consumption, an economic dispatch of community-integrated energy systems considering demand-side coordinated response is proposed. Firstly, according to various energy characteristics, mathematical models of various energy forms are established, including wind energy, photovoltaic, gas turbine, gas boiler, and other component characteristics modeling. Secondly, an economic optimal scheduling model of community-integrated energy system considering demand side response is established, including the constraints and objective functions of the optimization model, and the optimization model is solved based on the Yalmip toolbox and Cplex solver in Matlab software. Finally, the effectiveness of the proposed strategy is verified by a simulation example.

In this process, Hydrochloric acid (HCl) is often used to treat CaCO3 scale, posing the risk of pipe corrosion due to its high corrosive characteristics. Thus, the purpose of this study was to determine the impact of adding EDTA additive into HCl solution during the acidifying treatment procedure. The methodology included various stages such as scale identification, chemical scale removal test using 7.5% and 15% HCL solution, 15% HCl solution test with EDTA as an additive, and corrosion determination using corrosion coupon. The results showed that 15% HCl solution was very effective in removing CaCO3 scale but had a high corrosion rate of 186.255 mpy. Furthermore, the addition of 10 mL EDTA solution as an additive removed scale and reduced corrosion rate by approximately 85%.

Nitro compounds play a crucial role in academia and industries, serving as building blocks for the synthesis of drugs, agrochemicals, and materials. Nitration, a fundamental process in organic synthesis, has undergone significant evolution since the 19th century. While electrophilic nitration dominates historically, recent decades have seen a focus on new reagents and their reactivity modes for achieving mild and robust synthesis of nitro compounds. Our group has a longstanding interest in developing cost-effective, readily available, recyclable nitrating reagents derived from organic scaffolds. These reagents serve as a controllable source of nitryl radical and nitronium ion species, enabling mild and practical nitration of hydrocarbons with exceptional functional group tolerance. This account details the development of nitrating reagents and their diverse applications in catalytic nitration across various classes of organic molecules.
Capturing the Chirality of Photoexcited States with Ultrafast Circular Dichroism
Authors: Oppermann Malte
Published: February 2024

Chiral molecules exist in two forms, called enantiomers, which are mirror images of each other but non-superimposable. Even though enantiomers share most chemical and physical properties, they may differ greatly in their (bio-)chemical activities, which turns chirality into a key design feature for (bio-)chemical function. In this spirit, the incorporation of chiral structures into photochemical systems has emerged as a powerful strategy to control their functions. For example, uni-directional molecular motors, chiral photocatalysts, and chiral metal nanostructures permit new levels of stereocontrol over mechanical motion, energy transfer, and electric charge-carriers on the nanoscale. However, the direct characterization of the underlying chiral photoexcited states remains a formidable experimental challenge - especially in the native solution phase of many photochemical processes. Crucially, this requires analytical techniques that combine a high chiral sensitivity in solution with ultrafast time resolution to capture the excited state dynamics. This brief perspective article presents recent progress in the development of ultrafast chiral spectroscopy techniques that address this challenge.

Pirquitasite Ag2ZnSnS4 (AZTS) nanocrystals (NCs) are emergent, lead-free emissive materials in the coinage chalcogenide family with applications in optoelectronic technologies. Like many multinary nanomaterials, their phase-pure synthesis is complicated by the generation of e.g. binary/ternary chalcogenide and metallic impurities. Here, we develop a stepwise synthetic procedure that controls the size, morphology, and transformations of acanthite-like (Ag2S) and canfieldite-like (Ag8SnS6) intermediates. This reaction scheme grants the production of small AZTS NCs (diameter: 2.1–4.0 nm) that have not been achieved through established single-injection procedures—expanding the accessible range of quantum-confined AZTS emission to shorter wavelengths (λ: 650–740 nm). We show that the initial sulfur stoichiometry is the key handle for template-size tunability and reveal that temporally separating transformation steps is crucial to obtaining phase-pure AZTS NCs with emission λ<740 nm. We then use NMR and optical spectroscopies to demonstrate that the installation of thiol ligands improves colloidal stability, while exposure to carboxylic acids does not. Finally, facilitated by this enhanced synthetic control, we show that our ultra-small AZTS NCs can act as effective, less-toxic sensitizers for red-to-blue triplet fusion upconversion. Our results highlight transferrable insights for the synthesis and post-synthetic treatment of complex less-toxic quaternary nanocrystalline systems.

Poly-L-hydroxyproline (PHyp) is a synthetic analogue of collagen, the most abundant protein for animals, and holds immense potential for broad biomedical applications. The synthesis of PHyp, however, involves inefficient protection-deprotection steps and has been restricted to relatively low molecular weight (MW) and linear topology. Here, we report the ring-opening polymerization (ROP) of unprotected hydroxyproline N-carboxyanhydrides (Hyp-NCA) for the facile one-step synthesis of PHyp with tunable linear or branching topologies. Employing an innovative water-assisted ultrafast polymerization technique, the research achieves the synthesis of linear PHyp with MW up to 7.5 kDa, featuring adjustable terminal groups and narrow dispersity. The study further introduces a tertiary amine-triggered one-pot polymerization method in DMSO, which leads to the preparation of branched PHyp (B-PHyp) with MW up to 438 kDa, ~40 times higher than previous record of PHyp. Facile post-polymerization modification of B-PHyp affords injectable hydrogels with a critical gelization concentration as low as 1.0%. The polymers, characterized by their distinctive collagen-like polyproline type II (PPII) helices, offer significant prospects in drug delivery, wound healing, and other biomedical applications.
Scaling relations on high-entropy alloy catalyst surfaces

Scaling and Brøndsted-Evans-Polanai (BEP) relations have proven immensely powerful in catalysis theory. The relations provide an understanding of the Sabatier principle in a quantitative fashion, such that we can calculate the adsorption energy that most optimally compromises between a low reaction barrier and a not too strong absorption. Scaling and BEP relations are usually mapped out for pure metal surfaces and it is not directly clear how they translate to complex alloy surfaces, e.g. high-entropy alloys (HEAs). The scaling relation between *OH and *OOH is one of the most studied and best understood. Generally, both *OH and *OOH adsorb on a single surface atom, so HEAs do not change the established scaling relation, but rather widen the distribution of available adsorption energies. The situation can be different for reactions at multi-atom surface sites. The reaction between O* and *CO to form CO2 interact with more surface atoms at the initial state compared to the transition state, so for a given reaction energy, HEAs allow for lower activation energies than pure metals. The reason is that HEA surfaces can make the transition state more similar to the initial state, without the need of steps or other geometric features.
