The Representation of Love in Manon Lescaut by Abbé Prévost
Authors: Petre Andreea
Published: November 2023

This work analyses the way in which the representation of love in the novel Manon Lescaut by Prévost highlights some important aspects that mark the perception of love in the eighteenth century. Following the literary tradition of Classicism, according to which passionate love is a source of evil and even of the protagonists’ death, in Prévost’s novel, the Chevalier Des Grieux’s passionate love arises from the concern of the Age of Enlightenment to emphasize the importance of individual identity, which implies the freedom and courage to decide on one’s own life, the refusal of one’s positioning in an inherited hierarchy, at the top of which there lies the paternal or divine authority. To illustrate this conviction, Prévost builds a love story in which the male character occupies the privileged place, and femininity does not represent strangeness or otherness but an artificial entity, one created from within the male figure to capture his departure from the original, paradisiacal state of moral perfection. Under these circumstances, the construction of the female character becomes a tribute to the literary tradition of the representation of charm and beauty as sources of the extreme degradation of the male character.
The Use of Formants’ Correlation in Assessing the Sadness State of the Speakers
Authors: Ghelţu Ștefan-Andrei
Published: November 2023

The purpose of this study is to further the comparative analysis of the variations in the correlation coefficients of the formants for the Romanian vowels during emotional speech. We created an annotated speech database composed of recordings of speakers pronouncing the following sentences: /vine mama/ (/mother is coming/), /aseară/ (/last night/), /cine a făcut asta/ (/who did this/), first on a neutral tone of voice, and then expressing sadness.

The analysis focuses on the influence that sadness has on the vocal signal. The formants and F0 (pitch) of each vowel were extracted. Statistical analysis techniques were applied in order to verify whether the variation of the correlation coefficients between F0 and F1-F4 presents significant variations or whether it tends to be homogenous under the following conditions: (1) same speaker – same vowel – different sentences; (2) same speaker – same vowel – emotional neutrality vs. sadness; (3) different speakers – same sentence – same vowel.

Published: November 2023

The obtained results indicate the possibility of weed control in organic intercropping production systems of carrots and onions with the application of corn gluten, together with the ecological assessment of habitat based on bioindicator values of weed species. A total of 29 weed taxons are present in the intercoped and pure crops of carrots and onions, grown without (CO) and with the application of corn gluten (CO-G). Although floristically uniformed, 24 taxons (CO) and 23 taxons (CO-G), the total weediness on the CO-G variants was 24% higher. The highest value of fresh weed biomass was recorded on the treatment of pure onion crop with gluten application (2844.85 g/m2), while the lowest value was recorded on the treatment of intercropped carrot and onion (1004.99 g/m2). Ecological assessment of habitat, based on indicator values and abundance of weed species, indicates favorable climatic conditions with favorable temperature (Tx̄ - 4) and light (Lx̄ - 4) regime, which refers to temperate continental climate conditions (Kx̄ - 2,7). Soil indicators indicate slightly drier conditions (Fx̄ – 2,6), slightly acidic to neutral pH (Rx̄ – 3,3), rich in nutrients (Nx̄ – 4), with moderate humus content (Hx̄ – 3), moderate aeration (Dx̄ – 2,8) and locally salted (s) with the participation of salinity indicators in the amount of 54% (CO) and 40% (CO-G). The presence of heavy metals tolerance (m) indicators in the amount of 46% (CO-G) and 41% (CO) should not be neglected, which imposes the need for additional analysis of soil for heavy metal content. Based on the analysis of obtained indicator values, it can be concluded that these ecological conditions correspond to the development of carrots and onions and that the lowest values of fresh weed biomass were recorded on the treatment of intercropping of carrots and onions, without application of corn gluten.

Published: November 2023

This study was conducted to examine perceived effects of crop diversification on food security status of maize-based farmers in Kwara State, Nigeria. A multi-stage sampling technique was employed to obtain data from 183 maize-based farmers using an interview schedule. The data were analyzed using Herfindahl indexing, Food Consumption Score of the World Food Programme for determining household food security and Chi-square test. The results showed that the extent of crop diversification was moderate for slightly above half of the respondents (51.4%). The majority of the respondents (91.3%) had acceptable food consumption (>35), which corresponds to their food security situation. Crop diversification among the farmers indicated positive and significant influence of crop diversification on the food security status of the farmers at 1% level of significance using chi-square. More than half of the respondents perceived that crop diversification had strong effects on increased access to food preferences for an active and healthy life (56.3%), access to utilizable and digestible food (57.4%) and access to sufficient food (53.6%). The study concluded that crop diversification practices contributed to food security by increasing access to preferred sufficient, utilizable and digestible food for active and healthy life of maize-based farmers in Kwara State. Thus, extension agents should increase awareness of the importance of crop diversification for the farmers’ output in the study area.

Published: November 2023

The characterization of animal genetic resources includes morphometric, production and genetic characterization. This paper aims to determine the annual yield, staple length, and physico-mechanical properties of the wool of the Dupska Pramenka sheep. The average annual wool yields of a total of 130 ewes and 14 rams enrolled in the study were 2.120 kg and 3.340 kg, respectively. Wool samples were taken from the left shoulder, posterior rib, and pelvis of a total of 50 sheep (36 ewes and 14 rams). The lengths of wool staples collected from three body sites of the ewes were 20.92 cm, 21.75 cm, and 22.25 cm, respectively. The lengths of wool staples collected from three body sites of rams were 23.50 cm, 22.14 cm, and 23.64 cm, respectively. The height and length of wool fibers of the ewes were 21.97 cm and 22.85 cm on the shoulder, 22.38 cm and 23.10 cm on the posterior rib, and 23.06 cm and 23.77 cm on the pelvis. The height and length of wool fibers of the rams were 22.00 cm and 22.89 cm on the shoulder, 22.54 cm and 23.26 cm on the posterior rib, and 22.61 cm and 23.40 cm on the pelvis. The average fineness of wool fibers of the ewes was 43.08 µ, whereas the fineness of wool fibers of the rams was 45.43 µ. The Dupska Pramenka sheep were found to have mixed fibers: axillary (over 45µ), accounting for51.64% in the ewes and 54.91% in the rams, and transitional (30–45µ), accounting for 28.76% in the ewes and 32.80% in the rams. Fiber fluff (10–30µ) accounted for 19.83% and 12.98% in the fleeces of ewes and rams considered, respectively.

Published: November 2023

Speech is one of the most serious manifestations of Parkinson's disease (PD). Sophisticated language/speech models have already demonstrated impressive performance on a variety of tasks, including classification. By analysing large amounts of data from a given setting, these models can identify patterns that would be difficult for clinicians to detect. We focus on evaluating the performance of a large self-supervised speech representation model, wav2vec, for PD classification. Based on the computed wav2vec embedding for each available speech signal, we calculated two sets of 512 derived features, wav2vec-sum and wav2vec-mean. Unlike traditional signal processing methods, this approach can learn a suitable representation of the signal directly from the data without requiring manual or hand-crafted feature extraction. Using an ensemble random forest classifier, we evaluated the embedding-based features on three different healthy vs. PD datasets (participants rhythmically repeat syllables /pa/, Italian dataset and English dataset). The obtained results showed that the wav2vec signal representation was accurate, with a minimum area under the receiver operating characteristic curve (AUROC) of 0.77 for the /pa/ task and the best AUROC of 0.98 for the Italian speech classification. The findings highlight the potential of the generalisability of the wav2vec features and the performance of these features in the cross-database scenarios.
Born Globals and Born Sustainables: Motives of Accumulating Wealth and of Making a Difference in the World
Authors: Širec Karin , Samsami Mahsa , Schøtt Thomas
Published: November 2023

Background/Purpose

This study investigates the distinct entrepreneurial motivations driving export activities and sustainability pursuits in Slovenian businesses, with a particular focus on differences between newborns and mature enterprises. The study proposes that entrepreneurs who prioritize wealth accumulation are more likely to engage in export activities, particularly those running startups, under the pressures of global trade. Conversely, in light of the shifting cultural values towards sustainability, it is hypothesized that entrepreneurs who are committed to making a difference in the world will be more inclined towards sustainability engagement, a tendency that may be more pronounced in startups.

Methods

To test these hypotheses, linear regression modelling, using data collected from the Global Entrepreneurship Monitor survey of businesses in Slovenia was employed.

Results

Newborns, in comparison to mature businesses, are more engaged in both exporting and sustainability pursuits. Interestingly, the motives behind these activities differ significantly. Exporting is primarily driven by the pursuit of wealth accumulation, while sustainability engagement is motivated by the desire to make a positive difference in the world.

Conclusion

These findings provide valuable insights into the unique characteristics of internationalization and sustainability pursuits in startups versus mature businesses. They highlight the role of distinct entrepreneurial motivations in shaping business practices, contributing to the literature on entrepreneurship and business sustainability.

Authors: Kukołowicz Paweł , Szalkowski Dariusz , Jackowska-Zduniak Beata , Tarchalski Mikołaj
Published: November 2023

Introduction: The geometrical precision of the machines is essential for effective and safe radiotherapy. Methods currently used for the measurement of the mechanical isocenter have many limitations. In this work, the optical system NaviRation for very precise measurement of mechanical accelerator isocenter is described. The results of the measurement of the isocenter for linear accelerator are also presented.

Materials and methods: An optical system for measuring the accelerator isocenter was designed and built. The optical system consists of two cameras recording the target position made according to a patented Zeiss technology. About 1,200 pairs of images are recorded during the rotation of the gantry, collimator and treatment table. Mathematical analysis of these images makes it possible to determine the location of the target center during rotation. In order to verify the accuracy of the measurements, a device simulating rotational motion was designed. The measurement results were also verified at the Central Office of Measures. The system must be calibrated each time before taking measurements. In this article, we present the results of measurements for the Versa HD accelerator.

Results: The accuracy of determining the current position of the axis of rotation was 0.15 mm. The time of taking measurements of all rotations does not exceed 20 minutes. Measurement results for the Versa HD accelerator showed that this accelerator met the criteria described by TG142 of the AAPM. The diameter of the gantry, collimator and table isocenter spheres were 1.5 mm, 0.3 mm and 0.4 mm, respectively.

Conclusions: The system enables precise, fast and simple mechanical isocenter measurement of the gantry, collimator and treatment table. It is also possible to perform all tests related to the measurements of distances, e.g. quality control of distance indicator, and distance of the table movement. The isocenter is measured independently of the accelerator for which measurements are made.

Authors: Pettinaroli Andrea , Susani Stefano , Castellanza Riccardo , Collina Elena Maria , Pierani Matteo , Paoli Riccardo , Romagnoli Francesco
Published: November 2023

Urban growth needs large cities, and the current emphasis on landscape preservation makes using underground spaces an opportunity and a significant necessity. However, underground construction techniques significantly impact the sustainability of the built environment, including infrastructure systems and their entire supply chains. Nowadays, there is a shortage of quantitative methodologies to assess and measure the sustainability of construction and underground building processes towards the three sustainable pillars, i.e. environmental, social, and economic. Thus, this study aims to cover this gap by explaining how to appropriately incorporate sustainability goals into geotechnical projects to address measure-driven strategies and eco-design-based solutions. This study illustrates a novel methodology based on the Life Cycle Thinking approach, with an emphasis on geotechnical ground improvement techniques. The proposed method incorporates the concept of the EU Taxonomy, following the EU Green Deal, with the Envision framework to guide decision-makers toward a more sustainable, resilient, and equitable infrastructure design. The proposed method will incorporate a cradle-to-site Life Cycle Assessment perspective, improving the quantitative estimation of the environmental performance of construction processes and providing guidelines to systematically assess the sustainability of geotechnical infrastructures.

In this article, we use the notion of ideals to study open covers and related selection principles, and thus, we extend some results in (Caserta et al. 2012; Chandra et al. 2020) where open covers and related selection principles have been investigated using the idea of strong uniform convergence (Beer and Levi, 2009) on a bornology. We introduce the notions of ℐ-γ
ℬ
s -cover, ℐ-strong-ℬ-Hurewicz and ℐ-strong-ℬ-groupable cover. Also, in (C(X),τsℬ), some properties like ℐ-strictly Frèchet Urysohn, ℐ-Reznichenko property are investigated.
Multipliers of Variationally Mcshane Integrable Functions in Locally Convex Space
Authors: Bhatnagar Savita
Published: November 2023

We study measurable real valued multipliers of variationally McShane (resp. McShane) integrable functions defined on a σ-finite outer regular quasi-Radon measure space and taking values in a complete locally convex topological vector space X. We also show: in case X is representable by semi-norm then essentially bounded real measurable functions are multipliers of functions which are Pettis integrable as well as integrable by semi-norm. The space of real valued measurable and essentially bounded functions turn out to be precisely the multipliers of variationally McShane (resp. McShane) integrable functions in case X is representable by semi-norm.

Scripting Scenarios of Pedestrian Behavior in a Computer Simulator of Security Monitoring System: A Practitioner’s Perspective
Authors: Sugier Jarosław
Published: November 2023

The subject of this paper is the AvatarTraffic simulator – a computer system capable of modelling in real time environments such as subway stations or airport halls populated with tens or hundreds of moving figures, which, in addition to pedestrian traffic typical for this type of objects, can perform predefined sequences of events and actions formulated as a simulation scenario. Thanks to the integration with a real monitoring system, the simulator, in addition to providing data streams (including video) generated by the virtual scene, is also able to dynamically respond to actions taken by the system’s staff. Using the Unity simulation engine as the implementation platform, a number of practical problems had to be solved during the development, two of which are the subject of this article: a) supervising and correcting the work of AI algorithms used in Unity to simulate the pedestrian movement of avatars, and b) a textual description of the scenario of events taking place on the stage in a way editable for experts planning tests of the monitoring system. Some more challenging cases of people movement are discussed (including creating queues and passing through doors) and the paper presents original algorithms correcting the work of the Unity’s built-in methods in the situations when the coordinated behaviour of people groups is required. Because of the specifics of the simulator environment the scenario needed to be expressed in a JSON text file, and the article presents the implemented mechanisms of its compilation directly to the C# runtime environment and discusses the original command language which was created to model sequences of events and actions making up the scenario.
Phantomatic Road Works in Poland: A View from a Dashboard Cam

Published: November 2023

Correct signage belongs to critical factors affecting road traffic safety. During a naturalistic driving study in Poland major mistakes associated with signage were noticed and analysed: road works were announced and speed limits were reduced from 120 km/h to 70−80 km/h, but no road construction could be found. Measurements of drivers’ speed showed their complete disregard of the limitations: average speed of light vehicles remained at 113 km/h and lorries at 88 km/h. Assessment of the encountered 683 road signs revealed 12.5% of them to be inadequate (10.9% falsely informed drivers). Evaluation of contrast ratio of road markings (their replacement was the claimed reason for road work) showed low values both before and after re-placement (Weber contrast 0.6). It is hypothesised that erroneous road signage and its contradiction with the visible road features are contributing to the permanent disobedience of traffic rules in Poland and are decreasing road safety.

Published: November 2023

Drivers play a significant role in causing serious accidents, which underscores the need for further investigating the human element in order to improve road safety. Given the predominance of the information processing approach in driver’s behavior research field, an important psychological construct, Mental Workload (MWL), has been introduced to study the behavior of drivers. The objective of this paper is to investigate the impact of increased MWL on driver behavior and specifically the changes in driver’s Reaction Time (RT) under increased MWL. The experiment conducted in the driving simulator of the Hellenic Institute of Transport which is part of the Centre for Research and Technology Hellas, with the participation of 56 subjects from all age groups. For the simulation of the increased MWL conditions during driving, a secondary task was employed. To this end, the MIT AgeLab Delayed Digit Recall Task in the 1-back version was adapted for the needs of the present research. The driving scenario included 4 unexpected events, which further increase driver’s MWL. Driving performance was observed and relative parameters were measured as RT on the unexpected events, accidents occurred, and maneuvers performed. Appropriate statistical analysis was performed to examine the difference in the drivers’ RT in the unexpected events. Results demonstrated that higher MWL increased drivers’ RT in the majority of the participants. Furthermore, results also indicated a number of participants that probably employed adaptive control behaviors to counterbalance the increased MWL. Overall, variance on MWL proved to play an important role on driver performance, and thus further research on its consequences on driving performance, and the factors that influence its variance during driving, is imperative.

The utilization of simulation modelling in supply chain management has proven to be a valuable tool for logistics service providers, enabling them to optimize their operations and meet customer demands efficiently. AnyLogic, with its diverse capabilities in discrete event simulation, system dynamics, and agent-based simulation, stands out as a powerful software solution for tackling complex supply chain challenges. This paper significantly contributes by demonstrating the practical implementation of AnyLogic in the modelling and simulation of agro-food product distribution network, particularly vegetable oils from the Cevital group. Additionally, the study integrates an optimization experiment to ascertain the optimal number of vehicles required to meet a specific customer demand while ensuring a high level of fleet utilization. The obtained results are very encouraging and demonstrate the feasibility and effectiveness of our approach.
Analysing Distribution Approaches for Efficient Urban Logistics
Authors: Salehi Salar , Ippolito Nicola , Gentile Guido , Miristice Lory Michelle Bresciani
Published: November 2023

Urban logistics plays a crucial role in modern society by covering all the flows of goods and services in the transportation world. This study aims to compare different delivery distribution scenarios using the aggregation of stops by grouping entities, for instance, the postal code approach (PCA) and the volume-based approach (VBA), to indicate the most effective one in simplifying urban logistic operations. These two scenarios illustrate two aggregation criteria: geographical, which groups stops with those closest ones, and non-geographical, which tends to cluster stops with similar stops. Used stops came from a real-world dataset acquired from urban logistics operator in the East of Rome. This study uses an optimizing algorithm called Traveling Salesman Problem (TSP) and Google Matrix API to calculate the shortest path and travel time. A comparison of those two approaches has been made to illustrate the similarities and differences in CO2 emissions, travel length, travel time, and unloading time. Although PCA is influenced by demand level, results show that PCA leads to a shorter travel time, shorter travel length, and less emissions produced. Furthermore, VBA is a more heterogenous distribution while PCA contains more homogeneity. The outcome could have the potential for companies and researchers interested in urban logistics due to the proposal of a new way of making distributions, real-world data usage, and comparing different scenarios.

Authors: Mrkývka Petr , Šiková Zuzana
Published: November 2023

This article deals with the phenomenon of Robo-advisory used in the provision of investment services. It is appropriate to consider the use of this tool from a regulatory perspective, particularly given the widespread use of digital tools in financial markets and the growing interest of users in the digitization of services. Given the rapid development of digitalization, legislation may not always take into account the use of digital tools. Legislative changes may be delayed. The main objective of this article is to analyze Robo-advisory specifically from the perspective of EU regulation. The aim is to confirm or disprove the hypothesis. Based on the analysis, we are then able to look at using Robo-advisory from different perspectives, both practical and regulatory. The analysis also highlights the similarities and differences between traditional and alternative investment service provision.

В статье проанализирован институт прекращения гражданства Российской Федерации с учетом принятия Федерального закона от 28 апреля 2023 г. № 138-ФЗ «О гражданстве Российской Федерации», который вступает в силу 26 октября 2023 г. Сложность анализируемого института обусловливает отсутствие единой правовой и исследовательской позиции относительно вопроса определения терминов «прекращение гражданства», «лишение гражданства», «отмена решений по вопросам гражданства», «утрата гражданства». В результате исследования сформулированы предложения по совершенствованию правовых норм, составляющих институт прекращения гражданства РФ. В частности, автор предлагает на законодательном уровне закрепить определения понятий «прекращение гражданства» и «лишение гражданства» с целью их разграничения.

The article provides analysis of the institute of termination of Russian citizenship in view of the adoption of Federal Law of 28 April 2023 No. 138-FZ «On Russian Federation Citizenship» which comes into force on October 26, 2023. The complexity of the institution under analysis deals with the lack of unified legal and research position with regard to defining terms «termination of citizenship», «deprivation of citizenship», «revocation of citizenship decisions», «loss of citizenship». As a result of the research there have been formulated proposals for improving legal norms constituting the institution of termination of Russian citizenship. In particular the author suggests that definitions of terms «termination of citizenship» and «deprivation of citizenship» should be enshrined at legislative level in order to distinguish between the ones.

Published: November 2023

Herein, we provide eco-friendly and safely operated electrocatalytic methods for the selective oxidation directly or with water, air, light, metal catalyst or other mediators serving as the only oxygen supply. Heavy metals, stoichiometric chemical oxidants, or harsh conditions were drawbacks of earlier oxidative cleavage techniques. It has recently come to light that a crucial stage in the deconstruction of plastic waste and the utilization of biomass is the selective activation of inert C(sp3)–C/H(sp3) bonds, which continues to be a significant obstacle in the chemical upcycling of resistant polyolefin waste. An appealing alternative to chemical oxidations using oxygen and catalystsis direct or indirect electrochemical conversion. An essential transition in the chemical and pharmaceutical industries is the electrochemical oxidation of C–H/C–C bonds. In this review, we discuss cutting-edge approaches to chemically recycle commercial plastics and feasible C–C/C–H bondsoxygenation routes for industrial scale-up.
Investigating the Non-Electrostatic Component of Substrate Positioning Dynamics
Authors: Jiang Yaoyukun , Ding Ning , Shao Qianzhen , Stull Sebastian , Cheng Zihao , Yang Zhongyue
Published: November 2023

Substrate positioning dynamics (SPD) orients the substrate to reactive conformations in the active site, accelerating enzymatic reactions. However, it remains unknown whether SPD effects originate primarily from electrostatic perturbation inside the enzyme or can independently mediate catalysis with a significant non-electrostatic component. Here we investigated how the non-electrostatic component of SPD affects transition state stabilization. Using high-throughput enzyme modeling, we selected Kemp eliminase variants with similar electrostatics inside the enzyme but significantly different SPD. The kinetic parameters of these selected mutants were experimentally characterized. We observed a valley-shaped, two-segment linear correlation between the TS stabilization free energy (converted from kinetic parameters) and an index used to quantify SPD. Favorable SPD was observed for a distal mutant R154W, leading to the lowest activation free energy among the mutants tested. R154W involves an increased proportion of reactive conformations. These results indicate the contribution of the non-electrostatic component of SPD to mediating enzyme catalytic efficiency.
Instrumentation at the leading edge of proteomics
Authors: Peters-Clarke Trent , Coon Joshua , Riley Nicholas
Published: November 2023

The proteome, or collection of proteoforms expressed in a biological system, is dynamic and heterogeneous. As our appreciation for the complexity of the proteome has evolved, so have the technologies we use to interrogate its composition. More than three decades ago, a rapid expansion in the field of proteomics was driven by the advent of soft ionization techniques focusing on capturing protein sequence information using mass spectrometry (MS). As tools to automate peptide and protein sequencing with tandem MS (MS/MS) matured, our field recognized the limits of qualitatively cataloguing gene products.1,2 This realization drove a multi-pronged expansion of MS-centric technologies that seek to capture various aspects of proteins, including their abundance, modification states, conformation and structure, and spatiotemporal relationships.3–7 Here we review innovations in MS-based instrumentation that continue to expand our ability to survey the proteome with ever increasing sensitivity, speed, and flexibility. The march of progress in MS instrumentation has been steady over the better half of the past century, but our discussion here focuses on developments within the past five years that have ushered in an exciting era in proteomics, where MS is poised to be the dominant platform for exploring biological phenotypes in basic and translational sciences for the foreseeable future.
Implicating the Role of Au-H Bonds in Photochemical N2 Fixation by Ruthenium Doped Gold Clusters

Published: November 2023

Dinitrogen fixation through the Nitrogen Reduction Reaction (NRR) under mild conditions without the use of sacrificial agents has its share of formidable hurdles. It has been shown recently that Ru-doped Au nanoclusters can reduce N2 molecule to NH3 only in the presence of UV-Vis light in aqueous medium. Herein, using theoretical techniques (Density Functional Theory) we shed light on the mechanistic avenues traversed for achieving this prodigious chemical feat. Our findings suggest that the bimetallic Au22Ru6 cluster successfully accomplishes the NRR process under ambient pressure and temperature conditions by the very virtue of its bifunctional nature. Contrary to the existing views, we find that NRR propagates through an alternative associative pathway, where the Ru dopant assists in N2 adsorption while the Au-H bonds formed from Au assisted water splitting is implicated for facilitating NRR.

Synthetic cannabinoids, a subclass of new psychoactive substances (NPS), are lab-made substances that are chemically similar to those found naturally in the cannabis plant. Many of these substances are illicitly manufactured and have been associated with severe health problems, prompting a need to development analytical methods capable of characterizing both known and previously undetected compounds. This work focuses on a novel Structures for Lossless Ion Manipulations (SLIM) IM-MS approach to differentiation and structural characterization of synthetic cannabinoid metabolites, specifically MDA-19/BUTINACA, JWH-018, and JWH-250 isomer groups. These different compound classes are structurally very similar, differing only in the position of one or a few functional groups; this yielded similarity in measured collision cross section (CCS) values. However, the high resolution of SLIM IM provided adequate separation of many of these isomers, such as sodiated JWH-250 metabolites N-4-OH, N-5-OH, and 5-OH which displayed CCS of 187.5, 182.5, and 202.3 Å2, respectively. In challenging cases where baseline separation was precluded due to nearly identical CCS, such as for JWH-018 isomer, simple derivatization by dansyl chloride selectively reacted with the 6-OH compound to provide differentiation of all isomers using a combination of CCS and m/z. Finally, the opportunity to use this method for structural elucidation of unknowns was demonstrated using SLIM IM mobility-aligned MS/MS fragmentation. Different MDA-19/BUTINACA isomers were first mobility separated and then could be individually activated, yielding unique fragments for both targeted identification and structural determination. Overall, the described SLIM IM-MS/MS workflow provides significant potential as a rapid screening tool for characterization of emerging NPS such as synthetic cannabinoids and their metabolites.

We present a novel activity-based detection strategy for matrix metalloproteinase 2 (MMP2), a critical cancer protease biomarker, leveraging a mechanism responsive to the proteolytic activity of MMP2 and its integration with CRISPR-Cas12a-assisted signal amplification. We designed a chemical translator comprising two functional units — a peptide and a peptide nucleic acid (PNA) — fused together. The peptide presents the substrate of MMP2, while the PNA serves as a nucleic acid output for subsequent processing. This chemical translator was immobilized on micrometric magnetic beads as a physical support for an activity-based assay. We incorporated into our design a single-stranded DNA partially hybridized with the PNA sequence and bearing a region complementary to the RNA guide of CRISPR-Cas12a. The target-induced nuclease activity of Cas12a results in the degradation of FRET-labeled DNA reporters and amplified fluorescence signal, enabling detection of MMP2 in the low picomolar range, showing a limit of detection of 72 pg/mL. This study provides new design principles for a broader applicability of CRISPR-Cas-based biosensing.

Published: November 2023

In this study, the nonlinear model of the longitudinal motion and altitude of a fixed-wing unmanned aerial vehicle with assured geometrical features and aerodynamic parameters is linearized under certain conditions. A cascade Proportional Integral Differential Controller is designed on the linear model. The controller coefficients that applied to the model of the UAV were optimized with an artificial intelligence technique, which is based on a metaheuristic search algorithm. The four different controller gains in the system are optimized using four different objective functions. Controller performances were tested in simulation environment for unit step input responses., Considering the longitudinal dynamics of the aircraft, among the ITAE, ISE, MSE, and IAE fitness functions, IAE can be shown as the optimum result for altitude control.
Feladatok egyetemi hallgatók számára a ChatGPT korában: Az egyetemi pénzügyi oktatás példája

A fejlett mesterséges intelligencia rendszerek (MI), mint például a Chat Generative Pre-trained Transformer, továbbiakban ChatGPT megjelenésének egyik kulcsfontosságú részletkérdése, hogy a jövőben milyen hatékony és hatásos feladatokat készítsünk egyetemi hallgatók számára. Ez a konferenciatanulmány a szokásos órai és órán kívüli feladatok újragondolását tárgyalja a tanulás 4C modell (Critical thinking – Communication – Collaboration – Creativity modell) keretében. Olyan feladattípusok kerülnek bemutatásra a következőkben, melyek az MI megjelenése miatt szükségképpen nagyobb hangsúlyt kapnak az egyetemi oktatásban és azon belül az üzlet képzésekben, mivel a tananyag átadása során a hallgatók a kreatív gondolkodás, együttműködés, kommunikáció és kreativitás készségeket is használják. A pénzügyi oktatási példák a következő irányokat mutatják be: információ szempontjából problémás feladatok (hiányos, túláradó, félrevezető információt tartalmazó feladatok), a probléma ki- és megtalálása. strukturálása (egymondatos esettanulmányok), elemzések és megoldások szóbeli interpretációja (videóprezentáció és -verseny), és közvetlen tapasztalatok szerzése (online, papír & ceruza kísérletek).
