Authors: xiao kai
Published: June 2023

In this paper, a continuous-time insider trading model is investigated, we require that
an insider is a risk-seeking and market makers may receive partial signal on risky asset. With
the help of fifiltering theory and dynamic programming principle, the uniqueness and existence of
linear equilibrium is established. It shows that (i) as time goes by, residual information decrease,
but both trading intensity and market liquidity are increasing; (ii) As partial observation precise
increase, both market liquidity and residual information are decreasing, however, the trading
intensity will increase. On the whole, the risk-seeking insider is eager to trade all the trading

ASAP: an automatic sequential assignment program for solid state multidimensional NMR spectra
Authors: Chen Bo
Published: June 2023

We describe an automatic sequential assignment program (ASAP) for congested solid state NMR (ssNMR) spectra. Given the residue type assignments determined from the well resolved spectra, ASAP first applies auto-residue type assignment strategy (ARTIST) to group individual resonances in unassigned congested spectra into matched residue type assignments, accounting for all possible combinations. Then matched residue type assignment pairs are sequentially allocated by Monta Carlo simulated annealing (MCSA) algorithm. Analytical expressions are derived for critical steps to achieve optimized annealing, in agreement with direct visualization of assignments migration during annealing, provided by the diagnostic tools in ASAP. We point out that there are three types of local minima associated with mis-allocations of assignments in sequential assignment. Owing to the correlation established by ARTIST between inputs, ASAP demonstrates superior robustness against local minima compared to standard MCSA. Alternative strategies are described for accelerated convergence towards global minima and to avoid local minima. Taken together, the efficiency, accuracy and capability of structural determination by ssNMR can be greatly enhanced by ASAP.

Published: June 2023

Background
The learning curve for retzius sparing robotic radical prostatectomy is not fully understood.
Objective
This study attempts to identify the learning-curve across the first 130 cases of a single surgeon.
Design, Setting, and Participants:
All retzius sparing robotic radical prostatectomy cases performed by a single surgeon at a high-volume tertiary hospital between April 2019 and July 2022 were included.
Outcome Measurements and Statistical Analysis:
Outcome measures included positive surgical margin rate, complication rates and unplanned readmission to hospital, postoperative urinary continence, erectile function, and PSA measurement. Cases were divided chronologically into 3 groups and differences between groups assessed.
Results and Limitation:
130 RS-RARP cases were identified. Differences were found between groups in several areas. Positive surgical margin rate fell between Group 1 (30.2%) and Group 3 (9.1%). Safety, post-operative continence, erectile function and PSA remained stable. Median patient age increased between group 1 (59yrs) and Group 3 (66.5yrs) (P = 0.04). Proportion of patients with stage > T2 increased between Group 1 (27.9%) and Group 2 (41.9%) (P = 0.036). Median console time increased between Group 1 (120 mins) and Group 2 (150 mins,) (P = 0.01). Median gland weight increased between Group 1 (28g) and Group 3 (35.5g) (P < 0.001).
Conclusions
The positive surgical margin rate improved over the learning curve, despite the complexity of cases increasing, reflected in older patients, larger prostates and higher stage disease. Safety and functional outcomes are excellent throughout. The learning curve might be facilitated by careful case selection favouring smaller prostates with less advanced disease.
Patient Summary:
We analysed the learning-curve for Retzius-sparing robotic radical prostatectomy. Across the first 130 cases positive surgical margin rate fell; safety and continence remained excellent. Selection of smaller and less advanced cases may facilitate learning.

Published: June 2023

Although animal vectors facilitate algal dispersal, the specific role of individual vectors in the temporal dynamics of algal community establishment remains unclear. In this study, we investigated the effects of wind and animal vectors, specifically amphibians and odonates, on temporal variation in algal composition and abundance. We conducted a 33-day field experiment in 2018 with four treatments that included different propagule additives. We identified 74 algal species from 11 taxonomic groups, with Chlorophyceae being the most abundant. Species richness and density varied significantly after day 12. Similarity in species composition and density increased over time in all treatments, with more species added at the beginning of the experiment and more species lost at the end. Our results suggest that different vectors had different effects on the local beta-temporal diversity of algal communities. The influence of morphological differences among vectors and the number of dispersal vectors on the variation of beta diversity and community characteristics was observed. We found that dissimilarity changed more rapidly when there were multiple vectors capable of dispersing more individuals and species. The effectiveness of algal dispersal by different animal vectors and its influence on the temporal dynamics of algal communities can vary in different environments and over longer periods of time. Overall, our study highlights the importance of understanding dispersal control and its relationship to the temporal dynamics of algal communities
Competition between frustration and spin dimensionality in the classical antiferromagnetic $n$-vector model with arbitrary $n$
Authors: Konstantinidis Nikolaos P.
Published: June 2023

A new method to characterize the strength of magnetic frustration is proposed by calculating the minimum dimensionality of the absolute ground states of the classical nearest-neighbor antiferromagnetic nn-vector model with arbitrary nn. Platonic solids in three and four dimensions and Archimedean solids have lowest-energy configurations in a number of spin dimensions equal to their real-space dimensionality. Fullerene molecules and geodesic icosahedra can produce ground states in as many as five spin dimensions. Frustration is also characterized by the maximum value of the round-state energy when the exchange interactions are allowed to vary.

Typomorphic features of placer gold of the Sololi River basin (northeast of the Siberian platform)
Authors:   Diamond and Precious Metal Geology Institute SB RAS, Gerasimov Boris B.
Published: June 2023

Mineralogical features of placer gold and gold-sulfide ore occurrences of the Sololi river basin from the Sololi uplift of the Olenek arch have been studied. According to the typomorphic indicators, two types of gold are distinguished. The first type is gold of a tabular and lumpy shape, often with mineral indentation imprints. The inner structure is represented by granulation, and recrystallization, high-grade intergranular veins, and high-grade shells typical of the gold of intermediate reservoirs. This type of gold is characterized by a high fineness. The sources of this type of gold were gold-bearing intermediate reservoirs of the Permian and Riphean widely developed in the studied area. The second type of gold includes subrounded and poorly rounded gold, ore gold of hooked, tabular, crystalline and angular-lumpy shapes with a pitted-bumpy or flat surface, as well as large growths of gold with quartz. The fineness of this type of gold varies from low to very high. Its primary sources were probably quartz veins genetically related to the metamorphic rocks of the Eekit series and Precambrian rhyolites. Ore occurrence formed by the Late Permian clastic rocks during the processes of the Mesozoic tectonomagmatic activation is considered as an additional source of feeding. Establishment of indicators of low–temperature hydrothermal processes as mineral parageneses, such as mercury gold, cinnabar and barite, suggests shallow and low-temperature formation conditions of this ore occurrence.
Problems of users’ perception of financial statements according to international standards
Authors:   Lomonosov Moscow State University, Rodchenkov Mikhail V.
Published: June 2023

Goal: identify and evaluate the factors that significantly affect the current assessment by representatives of the business environment of the quality and functionality of reporting generated by management in accordance with international financial reporting standards, in terms of increasing the clarity, simplifying and reducing current reporting to improve its perception by users. Methodology: the applicable methodology included general scientific methods of cognition, including analysis and synthesis, and expert assessments. The main results were obtained using factorial and multivariate analysis tools. Findings: the results of the tests performed are statistically significant and indicate against the null hypothesis. A significant part of the reporting information is difficult to fully understand by investors and representatives of other groups of interested users who ambiguously assess the feasibility of simplifying and reducing current reporting in order to increase its consumer value. Originality and contribution of the author: the basis of the study is a statistical analysis of current primary data obtained during a survey of representatives of the business environment. The theoretical significance of the results obtained lies in the refinement of the structure and assessment of factors influencing the quality of perception by users of corporate reporting information prepared by management in accordance with international financial reporting standards. The practical significance of statistically justified conclusions about the importance of adjusting the level (adaptation) of the complexity of standards and disclosures to improve the consumer characteristics of financial statements generated by management is determined by the possibility of their use in management practice to improve the efficiency of information support for investors and improve the corporate governance system.
Upgrade of waste stabilization ponds to improve effluents for reuse purposes
Authors: Sinn Jochen , Agrawal Shelesh , Orschler Laura , Schubert Selina , Lackner Susanne
Published: June 2023

Waste stabilization pond (WSP) systems exist in many countries affected by climate change causing increasing demand for irrigation water. There is little long-term experience with WSP in Africa, and thus, this study provides a comprehensive investigation of a WSP in Namibia. One of its treatment trains was upgraded with mechanical and anaerobic pre-treatment, and post-treatment and compared to a second train without upgrades. The pre-treatment showed positive results on COD, TSS and partially pathogen removal. E. coli were reduced to the new EU reuse standard of 1,000 MPN/100 mL for fodder irrigation, P. aeruginosa stagnated and Enterococci levels increased. The main pathogen reduction happened during pre-treatment and in the baffled facultative pond. In contrast, the post-treatment only reduced 5% of algae-based chlorophyll-a. Among the top 20 genera, Pseudomonas was most dominant. With different upgrades, hygiene requirements especially for restricted fodder irrigation can be reached. At the same time, high total tCOD and TN effluent values did not meet different reuse standards. But as the tCOD mainly consists of algae, adding biomass and TN fertilizer to the barren soil, it raised the question if all parameters set in the standards are applicable for WSP or should be adapted to their specific purpose.

Published: June 2023

Increasing CO2 concentration, temperature rise, and changes in rainfall due to climate change are expected to influence groundwater resources in irrigated agricultural regions. A simulation study using AquaCrop and MODFLOW models was undertaken to assess the combined effects of increasing CO2 concentrations, temperature, and rainfall changes on groundwater behavior in a rice–wheat cropping region of northwest India. Simulations were carried out for the 2016–2099 period under two scenarios: increasing CO2 concentrations corresponding to different RCPs (Scenario-I) and at a constant CO2 concentration of 369.4 ppm (Scenario-II). The results indicate that elevated CO2 negates the effect of rising temperature on evapotranspiration (ET) and water demand, and thus, lower ET is simulated under Scenario-I than Scenario-II for different RCPs during the future periods. The lower projected ET resulted in lower rice (2.3%–6.3%) and wheat (1.4%–16.1%) irrigation demand under Scenario-I than under Scenario-II. Of all RCPs, the lowest groundwater level (GWL) decline of 9.2, 20.5, and 24.4 m from the reference GWL (18.85 m) at the end of the early, mid-, and end-century periods, respectively, is projected under RCP8.5 and Scenario-I. Simulation results indicate that CO2 concentration plays an important role while assessing climate change effects on groundwater in irrigated agricultural systems.
Polyphenolic Nano-formulations: A New Avenue against Bacterial Infection

Published: June 2023

:

The gradual emergence of new bacterial strains impervious to one or more antibiotics
necessitates discovering and applying natural alternatives. Among natural products,
various polyphenols exhibit antibacterial activity. However, polyphenols with biocompatible
and potent antibacterial characteristics are limited due to low aqueous solubility
and bioavailability; therefore, recent studies are considering new polyphenol formulations.
Nanoformulations of polyphenols, especially metal nanoparticles, are currently being
investigated for their potential antibacterial activity. Nanonization of such products increases
their solubility and helps attain a high surface-to-volume ratio and, therefore, a
higher reactivity of the nanonized products with better remedial potential than nonnanonized
products. Polyphenolic compounds with catechol and pyrogallol moieties efficiently
bond with many metal ions, especially Au and Ag. These synergistic effects exhibit
antibacterial pro-oxidant ROS generation, membrane damage, and biofilm eradication.
This review discusses various nano-delivery systems for considering polyphenols as antibacterial
agents.

Introduction:

We report herein on the design and development of matrix tablets containing potent
synthetic melatonin (MLT) receptor analogues, the x-fluoro-y-methoxy substitiuted phenylalkylamides (compounds
I-IV), the preparation and melatoninergic potency of which was recently communicated.

Methods:

The presence of the fluorine atom in compounds I-IV, besides not affecting their binding affinity,
compared to the pineal hormone melatonin, it also slows down their metabolism, which is a major drawback of
MLT. However, as fluorine increases the lipophilicity, solid pharmaceutical formulations of I-IV, involving the
appropriate biopolymers for their modified release in aqueous media, were developed in the context of the present
work.

Results:

The release profile of analogues I-IV was found to be similar to that of MLT and also of the commercially
available drug, Circadin®. Some of these systems are suitable for dealing with sleep onset problems,
whilst others for dealing with combined sleep onset/sleep maintenance problems.

Conclusion:

Apart from the nature and relevant content of the formulants used, this bimodal release profile of
the new analogues depends, to a large extent, on the diverse structural arrangement of their side chains in space,
as nicely demonstrated by the molecular dynamics calculations, conducted in the context of this study.

Published: June 2023

Introduction:

Psoriasis is a chronic skin condition caused by an autoimmune response
that accelerates the life cycle of skin cells, resulting in the characteristic symptoms of scaling,
inflammation, and itching.

Methods:

Palliative treatment options for psoriasis often prioritize the use of volatile oils. These
oils contain monoterpenes, sesquiterpenes, and phenylpropanoids that are intricately linked to the
molecular cascades involved in the pathogenesis and symptoms of psoriasis. To evaluate the antipsoriatic
efficacy of volatile oils and their components, we conducted a systematic review of
scientific studies. Our literature search encompassed various online databases, including PubMed,
BIREME, SCIELO, Open Grey, Scopus, and ScienceDirect. The selected studies included experimental
in vitro/in vivo assessments as well as clinical studies that examined the potential of volatile
oils and their extracts as antipsoriatic agents. We excluded conference proceedings, case reports,
editorials, and abstracts. Ultimately, we identified and evaluated a total of 12 studies for
inclusion in our analysis.

Results:

The data collected, compiled, and analyzed strongly support the interaction between volatile
oils and their constituents with the key molecular pathways involved in the pathogenesis of
psoriasis and the development of its symptoms. Volatile oils play a significant role in the palliative
treatment of psoriasis, while their chemical constituents have the potential to reduce the symptoms
and recurrence of this condition.

Conclusion:

The current review highlights that the constituents found in volatile oils offer distinct
chemical frameworks that can be regarded as promising starting points for the exploration and
development of innovative antipsoriatic agents.

benefits, such as antiviral, antitumour, anti-HIV, anti-inflammatory, antiparasitic, anticancer, and antifungal
effects. Curcumin, bisdemethoxycurcumin, and demethoxycurcumin are the major active and
stable bioactive constituents of curcuminoids. Curcumin, which is a hydroponic polyphenol, and the
main coloring agent in the rhizomes of turmeric, has anti-inflammatory, antioxidant, anti-cancer, and
anticarcinogenic activities, as well as beneficial effects for infectious diseases and Alzheimer's disease.
Bisdemethoxycurcumin possesses antioxidant, anti-cancer, and anti-metastasis activities. Demethoxycurcumin,
which is another major component, has anti-inflammatory, antiproliferative, and
anti-cancer activities and is the appropriate candidate for the treatment of Alzheimer's disease.

Conclusion:

The goal of this review is to highlight the health benefits of turmeric in both traditional
and modern pharmaceutical sciences by considering the important roles of curcuminoids and other
major chemical constituents of turmeric.

The threshold Limits for presidential and vice presidential candidates have been a prominent topic since the introduction of direct presidential elections. Initially, the presidential threshold aimed to determine the candidates competing in the presidential election. However, over time, it has become a subject of prolonged debate, as it was perceived to undermine the rights of individuals in government and impede the principle of equality in democracy. This study utilizes qualitative research methods to gauge public sentiment regarding implementing the presidential threshold in Indonesia's presidential election system after the 2019 election. The research collected data through the Nvivo 12 Plus, utilizing sources such as Twitter (with the hashtag #presidentialthreshold) and online news media outlets, including Kompas, Detik, Tempo, Republika, and TribunNews. The study findings indicate that the percentage requirement is the most frequently discussed topic regarding the presidential threshold. Tempo is the online news media outlet that prominently highlights the issue. The analysis reveals that negative sentiment prevails in public opinion, comprising 63% of responses, while positive sentiment constitutes 37%. Tempo primarily represents positive sentiment, while Republika reflects negative sentiment. Positive public sentiment focuses on parliamentary support, while negative sentiment centers around candidates' opportunities.

Briquettes are solids that are generally made from agricultural waste materials. Char briquettes are one of the alternative energies for daily needs. This study used char from palm shell and LDPE microwave-assisted co-pyrolysis at 450 Watts. The briquettes were made from the product of co-pyrolysis of palm shell and Low-Density Polyethylene (LDPE) with variations in the composition of 0:100, 50:50, and 100:0 and pressure of 50 kg/cm2, 100 kg/cm2, 150 kg/cm2, and 200 kg/cm2. In this research, thermogravimetry analysis (TGA) was the method used to determine combustion characteristics. This study aimed to determine the combustion characteristics, including the Initiation Temperature of Fixed Carbon (ITFC), Initiation Temperature of Volatile Matter (ITVM), Peak of weight loss rate Temperature (PT), Activation Energy (Ea), and Mass Loss Rate (MLR). The results showed that the increased briquettes pressure increases the ITVM, ITFC, PT, and EA. The higher LDPE composition in the briquettes decreased the ITVM, ITFC, PT, and Ea, but increased the MLR.

Patterns of formation of electrically conductive properties of oxides of the Magneli series
Authors: Ilinskiy A.V.  , Shadrin E.B.
Published: June 2023

The hybridization of vanadium ions and oxygen ions is considered for four vanadium oxides included in the Magneli series: VO, V2O3, VO2, V2O5. Based on the data on hybridization, the details of the structure of the crystal lattice of these oxides are analyzed. For each oxide, the role of electrons not participating in the stabilization of the crystal frame in the process of the semiconductor-metal phase transition was revealed. The complex Mott-Peierls character of the phase transitions in all the listed strongly correlated compounds has been established. It is shown that as the degree of oxidation of the V atom increases, the numerical value of the metallic conductivity of the high-temperature phase naturally decreases and, simultaneously, the temperature of the phase transition from the semiconductor to the metallic state increases. Keywords: phase transitions, Magneli series, electron correlations, hybridization of atomic orbitals.
Effect of Barrier Layer Roughness on the Formation of Nanoparticles of the Carbon Nanotube Growth Catalyst
Authors: Bulyarsky S. V.  , Dudin A. A.  , Litvinova K. I.  , Pavlov A. A.  , Rugakov G. A.
Published: June 2023

This article compares TiN layers produced by electron beam evaporation (EBE) and atomic layer deposition (ALD) for the effect of barrier layer deposition technology on the formation of carbon nanotube (CNT) growth catalyst nanoparticles. The layers obtained by EBE have a roughness 1.5 times higher than the layers deposited by the ALD method (Ra=1 nm and Ra=0.6 nm). Nanoparticles formed on the surface of the EBE layer are characterized by a large average size (about 30 nm) and a 1.3 times greater dispersion of the distribution compared to nanoparticles formed on the ALD layer. TiN layers obtained by EBE are characterized by better surface wettability in comparison with ALD layers. The contact angle for catalyst nanoparticles on the surface of the EBE layer of TiN is about 30 degrees and approaches 90 degrees for ALD layers. Catalyst spreading is due to the Wenzel model. It is shown that the higher surface roughness of the EBE samples is associated with the crystallization of TiN, since the layer formation process proceeds at a higher temperature compared to the ALD process. For this reason, the use of barrier layers obtained by the ALD method is preferable for the formation of CNT growth catalyst nanoparticles on their surface.

Published: June 2023

Background

Diabetes is a growing threat to public health, and secondary diseases like foot complications are common. Foot ulcers affect the individual’s quality of life and are a great cost to society. Regular foot examinations prevent foot ulcers and are a recommended approach both in Sweden and worldwide. Despite existing guidelines, there are differences in the execution of the foot examination, which results in care inequality. A structured foot examination form based on current guidelines was developed in this study as the first step toward digitalized support in the daily routine, and was validated by diabetes health care professionals.

Objective

The study aimed to validate a structured foot examination form by assessing health care professionals’ experiences of working with it “foot side” when examining patients with diabetes.

Methods

Semistructured interviews were held in a focus group and individually with 8 informants from different diabetes professions, who were interviewed regarding their experiences of working with the form in clinical practice. The users’ data were analyzed inductively using qualitative content analysis. The study is part of a larger project entitled “Optimised care of persons with diabetes and foot complications,” with Västra Götaland Region as the responsible health care authority, where the results will be further developed.

Results

Experiences of working with the form were that it simplified the foot examination by giving it an overview and a clear structure. Using the form made differences in work routines between individuals apparent. It was believed that implementing the form routinely would contribute to a more uniform execution. When patients had foot ulcers, the risk categories (established in guidelines) were perceived as contradictory. For example, there was uncertainty about the definition of chronic ulcers and callosities. The expectations were that the future digital format would simplify documentation and elucidate the foot examination, as well as contribute to the accessibility of updated and relevant data for all individuals concerned.

Conclusions

The foot examination form works well as a support tool during preventive foot examination, creates a basis for decision-making, and could contribute to a uniform and safer foot examination with more care equality in agreement with current guidelines.

The Relationship between Saudi Cadets’ Willingness to Communicate and Their English Language Proficiency
Authors: Alqahtani Ali Falah
Published: June 2023

This study examines a group of Saudi military cadets studying English as a foreign language and their willingness to communicate (WTC) using English. The study investigated the relationship between the cadets’ WTC using English and their English vocabulary size, along with the cadets’ perceived English competence. In addition, the study looked at the relationship between the Saudi military cadets’ WTC using English and their L2 anxiety. A survey was designed for and administered to 113 Saudi military cadets with an average age of 20 years old. Correlation and regression analyses revealed an association between the Saudi cadets’ WTC in L2 and the size of their English vocabulary. Furthermore, the study found a strong linear relationship between the students’ perception of their competence in English and their WTC in L2. However, the analysis showed a negative relationship between the Saudi cadets’ WTC using English and their L2 anxiety.

From Knowledge Transmission to Thinking Teaching: The Integrated Design of Interdisciplinary Curriculum for Empowering Minds
Authors: Yuan Chen
Published: June 2023

From the perspective of strategic development, quality education with the goal of developing core competencies has become an important dimension of global competition in the era of knowledge economy. The interdisciplinary curriculum restores the overall understanding and internal connection of oneself, nature, and society, with the goal of promoting learners’ mental health. It has become a necessary choice for the current development of core competencies, reflecting a shift in educational value orientation. Interdisciplinary courses utilize the relevant attributes of the edges of different disciplines to bridge the gap between disciplines, not only the integration of knowledge and skills, but also the careful integration of ideas and methods. The value orientation of interdisciplinary courses lies in enabling learners to construct open thinking patterns from their internal knowledge structure system, and cultivating learners’ literacy and abilities through subject integration and thinking integration. The implementation approach should gradually shift from integrating various courses and disciplines to integrating students with society, students with life, and forming an internal unity of knowledge and personality. The design of interdisciplinary courses has methods but no fixed form, and grasping its essence of thinking and constituent elements is the basis for design.

A REVIEW ON INFLAMMATORY BOWEL DISEASE
Authors: DESHMUKH CHINMAY DEVIDAS
Published: June 2023

The gastrointestinal tract commonly known as the digestive tract is one of the most important canals in the body. It consists of the passage from mouth to anus including organs that help in the digestion. The food is taken into the mouth and all essential nutrients, and vitamins are absorbed from the digestive tract. The tract consists of important digestive organs such as the pharynx, esophagus, stomach, intestine, and rectum. Although the word gastrointestinal includes the entire tract, most commonly it is the stomach and intestine. The process of digestion is complex including a variety of minor processes. This includes mastication of food, mixing with saliva to form a bolus, mixing with various gastric enzymes to form chyme, mixing with intestinal, pancreatic and hepatic juices, absorption, and extraction, removal of water and fecal compaction and elimination. These processes are very disciplined, round-the-clock, and systematic. However, there may be chances of certain problems in this routine work such as infections, inflammation, irritation, acidity, or diseases. Constipation, diarrhea, inflammatory bowel disease (IBD), fissure, piles, fistulas, and hemorrhoids are some of the common. The smooth and easy process of digestion of food and elimination of waste is disturbed due to any of these diseases. Certain environmental factors, genetics, gender and age, smoking, chair syndrome, and geographical factors are the main things of the development of IBD. IBD causes prolonged digestive tract inflammation. There are various other underlying symptoms of the disease which are discussed in the article. The two types of this disease are ulcerative colitis and Crohn’s disease. There are possible complications of these diseases such as malnutrition, weight loss, colon cancer, fistula, perforation, bowel rupture, etc. If these are not managed well in advance, then it may lead to the death of the person. To know more about the disease, the present review is an attempt to focus on all possible causes, clinical presentation, diagnosis, complications, and management of IBD. The experimental induction models are also tried to discuss in the present article.
