Pre- and Post-pandemic Analysis of Portugal’s Accommodation and Food Services Sector: a Shift-Share Approach
Authors: NUNES Alcina , ALVES Jéssica
Published: October 2024

Portugal’s tourism industry is essential to the nation’s economy, significantly contributing to wealth creation and employment opportunities. However, the onset of the global COVID-19 pandemic in 2020 severely impacted this vital sector. The accommodation and food services were particularly hit, with many businesses facing widespread closures. By early 2022, Portugal’s economy faced additional hurdles. Geopolitical tensions and rising inflation created further disruptions on a global scale, complicating the recovery process. Despite these obstacles, Portugal’s accommodation and food services sector began to show promising signs of recovery. To gain a deeper understanding of these dynamics, this paper utilizes shift-share analysis to examine the post-pandemic business landscape of Portugal’s accommodation and food services sector, focusing on data from 2019 to 2022 for active businesses and the number of persons employed. This analytical method breaks down growth into national, sectoral, and regional components, providing a comprehensive view of the factors influencing recovery. The findings indicate that regional and industrial factors played a more significant role in driving recovery than national economic trends alone. Notably, regions such as the Algarve, Madeira, and Açores demonstrated remarkable resilience and growth. These areas benefited from their unique competitive advantages within the sector, which helped them navigate the challenging post-pandemic environment more effectively. The study’s insights are invaluable for policymakers and investors. By understanding the importance of regional policies and innovation, stakeholders can make targeted decisions that enhance the sector’s competitiveness and sustainability.

Transformación curricular y competición deportiva escolar en Uruguay: una renovada oportunidad a la luz de la educación deportiva
Authors: Manzino Carla , Rodríguez Virginia , Sarni Mariana
Published: October 2024

Desde marzo del 2023 se está implementando en Uruguay una transformación curricular en la educación. El nuevo Marco Curricular Nacional sustituye en el primer nivel educativo al Programa de Educación Inicial y Primaria que regía desde 2009. Una de las novedades para el área de la educación física que potencia la enseñanza del saber disciplinar, es la incorporación del concepto de “educación deportiva” de Velázquez Buendía (2004) con sus tres dimensiones en las que propone intervenir: del practicante, espectador y consumidor. En este artículo y a partir de hallazgos de investigaciones anteriores en escuelas de Montevideo y del litoral norte del país (departamentos de Artigas, Salto, Paysandú, Río Negro y Soriano), reflexionamos sobre la enseñanza deportiva y su competición escolar, y revisamos su transposición didáctica y necesidad de pedagogización. Proponemos una serie de tareas que, desde las distintas dimensiones, aportarían al desarrollo de competencias generales y específicas de educación física propuestas en el nuevo marco curricular. De este modo la enseñanza de la competición deportiva escolar, propiciarían la educación de ciudadanos y ciudadanas participativos, críticos y comprometidos con el desarrollo de la cultura deportiva del país.

Published: October 2024

Objective: The objective of this study is to analyze the search for differentiated ethnic citizenship of the Quechua and Aymara peoples in Puno. It seeks to understand the struggle for recognition and social justice.
 
Theoretical Framework: It is based on the study of the socio-cultural and political movements of indigenous peoples, analyzing the tensions between the collective indigenous and individual values of Eurocentric citizenship, constructed from the political and legal perspective of the nation-state, based on the rationality and science of the Enlightenment of the eighteenth century.
 
Method: It is a historical and qualitative approach using in-depth interviews, documentary analysis and participant observation.
 
Results and Discussion: It reveals that the search for a differentiated ethnic citizenship among the Quechua and Aymara in Puno faces a homogenizing state structure that perpetuates social and cultural exclusion, generating constant contradictions and conflicts. This struggle for ethnic citizenship manifests itself both through culture and through social uprisings against homogenization policies.
 
Research Implications: Implement cross-cutting intercultural policies that promote participation and equal opportunities in decision-making in the local, regional and national agenda through horizontal dialogue.
 
Originality/value: It focuses on a historical and qualitative approach by proposing intercultural policies that promote cultural diversity through horizontal dialogue, confronting internal colonialism and promoting intercultural and differentiated citizenship.

Published: October 2024

Ocular trauma is the leading cause of noncongenital unilateral blindness in children under 20 years old. In this study, 138 patients (36 female, 102 male) with ocular trauma between November 1983 and October 1996 were reviewed retrospectively at the Department of Ophthalmology, Ondokuz Mayıs University Faculty of Medicine. Twenty- four of these patients were blunt trauma and 114 were perforating eye injury. The mean age of the patients was 6.96 ± 3.01 years. Mean post-treatment follow-up was 10.7 months (range 1 to 121 months). Forty-five patients were admitted to the eye clinic within the first 24 hours after trauma. The most frequent finding was hyphema in blunt injury, and corneal laceration in perforating injury. The most frequent cause of injury was wood and stone in blunt trauma and glass and knife in perforating trauma. While the ratio of visual acuities equal to or better than finger counting was 37.5 percent (9 eyes) in blunt trauma cases and 20.2 percent (23 eyes) In perforating trauma cases prior to treatment, it was 79.2 percent (19 eyes) and 55.3 percent (63 eyes), respectively, at last visit examination post-treatment. The most frequent complication was traumatic cataract in blunt trauma and corneal leukoma and anterior synechia in perforating trauma. The results obtained suggested that socioeconomic and sociocultural status and family negligence are important factors in eye injuries in children that occur during games.

Published: October 2024

Wilson's disease, an inborn defect of copper metabolism, is a fatal disease unless specific treatment is given. Hepatic presentation mimics almost all kinds of liver disease and the diagnosis is sometimes problematic. The diagnosis is based on clinical findings, family history, presence of Kayser-Fleischer rings, and results of key laboratory tests such as low serum ceruloplasmin level, increased urinary copper excretion and hepatic copper content.
We report four patients with Wilson's disease with hepatic manifestations with unknown there were difficulties in making the diagnosis because of normal serum ceruloplasmin levels. Inspite of normal ceruloplasmin levels and absence of Kayser- Fleischer rings, strong family history suggested Wilson's disease and the diagnosis was confirmed by increased urinary and hepatic copper amounts.

Authors: Öztunç Funda , Akalın Figen , Polat Bülent , Bilal Mehmet Salih
Published: October 2024

Sinus Valsalva aneurysm rupture (SVAR) is a rare cardiac abnormality that requires surgical correction when diagnosed. Previously, cardiac catheterization and angiography were thought to be necessary for its diagnosis. We present two pediatric cases of SVAR with subarterial ventricular septal defect (VSD) diagnosed noninvasively by echocardiography; surgical findings confirmed the diagnosis. In both of our cases the origin of SVAR was the right coronary sinus. The first case was ruptured into the right ventricular cavity; the second was ruptured into the right ventricular outflow tract.
Continuous murmurs heard during follow-up of children with VSD must alert the physician to this pathology. Combined two-dimensional, Doppler and color-Doppler echocardiography is an accurate, noninvasive method for diagnosis of SVAR.

Authors: Vikram Pradeep K , Rai Gopal , Lodhi Santram
Published: October 2024

Aim of current study was to screen various extracts of Eulophia herbacea tubers for anti-inflammatory effect on carrageenan induced paw oedema (acute models) and Cotton pellet granuloma model (chronic model) in experimental animals. Anti-inflammatory effects were observed by percent reduction in paw edema, assessment of granuloma weight and proinflammatory cytokine level. Diclofenac sodium (10 mg/kg bw) was utilized as standard drug for comparison. Study observation confirmed that ethanol extract (EEH) and aqueous extracts of Eulophia herbacea (AEH) tubers were reduces higher percentage of edema inhibition and comparable to the standard group. Granuloma weight of control group was increases after implantation of sterile pellet and was measured on after 8th day. A substantial (P<0.05) reduction in weight of granuloma was witnessed in EEH and AEH groups of animals at dose dependent manner. Level of proinflammatory markers (TNF-α, IL-6 and PGE2) were decreases significantly when compared granuloma tissue of control group of animals. In conclusion, ethanol and aqueous extracts of Eulophia herbacea tubers may reduce proliferative phase as proven by decrease in granuloma weight. Flavonoids present in ethanol extract and polysaccharides present in aqueous extract may be responsible for anti-inflammatory potential of Eulophia herbacea tubers.

Published: October 2024

Probiotics are the live bacteria that help the host's health. Paraprobiotics, defined as “inactivated microbial cells (non-viable) that confer a health benefit to the consumer,” hold the ability to regulate the adaptive and innate immune systems, exhibit anti-inflammatory, anti proliferative and antioxidant properties and exert antagonistic effect against pathogens. When it comes to developing functional foods and nutraceuticals, paraprobiotics—which include non-viable microbial components or metabolites derived from beneficial bacteria—offer fascinating opportunities. Nutraceuticals and functional foods are becoming more and more popular due to the increased need for preventative health strategies. Beyond just providing a basic diet, many goods have specific health benefits that help prevent disease and enhance overall wellbeing. Numerous health-promoting benefits of paraprobiotics include immunomodulation, improved gut health, and anti-inflammatory qualities. Paraprobiotic production techniques are always changing, resulting in increased cost and efficacy effectiveness. This review paper delves into the potential of paraprobiotics in shaping the future of functional food and nutraceutical development. By exploring their diverse functionalities, production methods, mechanism of action and integration into various food matrices, the paper aims to provide a comprehensive understanding of their potential impact.

This paper discusses a new method for measuring and calculating the angle of inclination of a railway support or a contact network support, using an unmanned aerial vehicle flying along a straight path, parallel to the railway track. A review of existing measurement methods is carried out, their advantages and disadvantages are indicated. In the method under consideration, it is proposed to measure angles and distances with six laser scanning rangefinders installed in threes on horizontal and inclined planes on an unmanned aerial vehicle. This allows you to increase the speed and accuracy of determining the angle of inclination of vertical supports. The calculations use the minimum distances from the laser scanning range finder to the top and bottom of the support surface. The formulas use geometric relationships and the cosine theorem to calculate the roll of supports taking into account their taper. Measuring distances and angles three times allows for averaging over them, which significantly increases the accuracy of calculations. A model experiment is carried out on a model of a reinforced concrete contact network support in four orientations. A comparison is made between theoretically calculated and experimentally measured distances and inclination angles. The accuracy of parameter determination complies with regulatory requirements.

Published: October 2024

The purpose of the study is to find a technique and conduct on its basis a harmonic analysis of the torque of an internal combustion engine for the subsequent determination of resonant vibrations of the crankshaft. The method of calculating the harmonics of the engine torque is given on the example of a YaMZ-5340 diesel engine with a power of 100 kW at a crankshaft rotation speed of 2300 min-1. Based on the results of thermal and dynamic calculation of the YaMZ-5340 engine, a graph of changes in its torque is constructed and harmonics of the first and second orders are calculated. The frequencies of natural and forced vibrations of the crankshaft and its resonant critical rotation frequency are determined. The number of the torque harmonic has been determined, which, according to the frequency of forced vibrations, coincides with the frequency of natural vibrations and causes resonance. The results of the study can be applied in the design and fine-tuning of engines in order to calculate and reduce torsional vibrations.

Authors: Ekundina Victor O. , Omon Emmanuel Akokhamen
Published: October 2024

Objectives:

Cervical cancer is a cancer arising from the cervix due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body, of which human papilloma virus (HPV) infection causes more than 90% of cases. This study aimed at investigating the mutational signatures retinoblastoma (RB) and p53 in HPV-associated squamous cell carcinoma (SCC) of the cervix.

Material and Methods:

A total of 10 formalin-fixed, paraffin-embedded tissue blocks, all consisting of SCC of the cervix, were used for this study. The technique employed was nucleic acid amplification technique and various steps for DNA sequencing including DNA extraction and polymerase chain reaction.

Results:

Mutation in the RB gene occurred at different gene regions ranging from 10 to 230, while p53 occurred at 10–945. The most prevalent mutational signature within the RB gene regions was T>C (37.50%), while the p53 gene region was T>A (23%). Percentage mutations at single-nucleotide polymorphisms (SNPs) of RB were transition (58.8%), transversion (41.2%), Indel (0%), and substitution (0%), while point mutations were missense (65%), silent (23%), and non-sense (12%), respectively. Mutations at SNPs of p53 were transversion (47.6%), transition (38.1%), Indel (14.3%), and substitution (0%), while point mutations were missense (78%), silent (22.2%), and non-sense (0%), respectively.

Conclusion:

Our results indicate that the inactivation of the normal functions of the tumor-suppressor proteins RB and p53 is an important step in human cervical carcinogenesis caused by mutation or from complex formation with the HPV oncoproteins.
Governance and ICT4D Initiative Success: A Longitudinal Field Study of Ten Villages in Rural India
Authors: Venkatesh Viswanath , Sykes Tracy Ann , Rai Arun , Setia Pankaj
Published: October 2024

Initiatives to leverage information and communication technologies for development (ICT4D) have attracted huge investments, especially in less developed countries. However, the success rate of such initiatives has been low. Prior research on this topic has argued for various individual and network characteristics as predictors of information and communication technology (ICT) use and consequent benefits. We argue that, in order to garner potential benefits of the local information and knowledge resources embedded in citizens’ advice networks, hybrid governance that combines leadership by the local government and the technology sponsor is required. We further theorize that leadership by the local government or the technology sponsor for different stages of the ICT4D initiative affects the salience of the pathways through which benefits of citizens’ advice networks accrue. We found support, in a longitudinal field study in 10 villages in India (2,980 heads of households), for our theory that hybrid governance modes outperform those that are homogeneous. Leadership by the local government for the pre-launch stage and by the technology sponsor for the post-launch stage was the most effective in promoting the behavioral pathway for economic benefits—that is, leveraging advice networks for ICT use and consequently realizing gains in income. In contrast, leadership by the technology sponsor for the pre-launch stage and by the local government for the post-launch stage was the most effective in promoting the informational pathway—that is, leveraging information and knowledge from advice networks to directly generate gains in income. Adjacent villages that did not have a similar ICT4D initiative did not experience a comparable growth in farmer income.
The Role of Affordances in the Deinstitutionalization of a Dysfunctional Health Management Information System in Kenya: An Identity Work Perspective
Authors: Bernardi Roberta , Sarker Suprateek , Sahay Sundeep
Published: October 2024

Improving the state of citizens’ health is an urgent priority in many low and middle income countries (LMICs), and health management information systems (HMIS) are widely seen as valuable tools for pursuing this priority. Yet, the potential of HMIS has been difficult to materialize in the LMIC context since routines and practices that work against effective use of HMIS are often deeply embedded in historical institutions and, consequently, are difficult to change. Using a longitudinal case study of HMIS in Kenya, we investigate the crucial role of identity work as a mechanism that links information technology (IT) affordances to institutions. In particular, our study revealed four types of identity work (disruptive, legitimizing, reinforcing, and transformative) that, through different affordances, led to distinct institutional consequences in terms of either maintaining or deinstitutionalizing existing dysfunctional HMIS-related routines and practices. We demonstrate the importance of context for theorizing the societal and development impact of IT and the role of IT materiality in influencing deinstitutionalization.
A Potato Salad with a Lemon Twist: Using a Supply-Side Shock to Study the Impact of Opportunistic Behavior on Crowdfunding Platforms
Authors: Geva Hilah , Barzilay Ohad , Oestreicher-Singer Gal
Published: October 2024

Crowdfunding platforms are peer-to-peer two-sided markets that enable amateur entrepreneurs to raise money online for their ventures. However, in allowing practically anyone to enter, such platforms enable opportunistic suppliers to flood the market with offerings, many of which are of low quality. This situation creates choice overload for potential backers and may thus influence their investment decisions. To empirically study the implications of this phenomenon for crowdfunding performance, we use a quasi-natural experiment in the form of an exogenous media shock that occurred on Kickstarter.com. The shock was followed by a sharp increase in the number of campaigns, particularly low-quality ones, offered on the supply side of the market; no such increase was observed on the demand side of the market. These unique conditions enable us to estimate how crowdfunding platforms are affected by the presence of an atypically large number of low-quality campaigns, while controlling for fluctuations in demand. We use two identification strategies, which enable us to control for changes in quality, to show that an increase in low-quality supply significantly decreases the performance of the average crowdfunding campaign, manifested in a lower likelihood of success (reaching funding goals) and less money raised per campaign. We also offer a new measure to estimate campaign quality and study the moderating role of campaign quality in the observed effects. We find that high-quality campaigns are less affected than low-quality campaigns by the influx of low-quality offerings. We discuss theoretical implications as well as managerial implications for entrepreneurs and platform designers.
Can Recommender Systems Reduce Healthcare Costs? The Role of Time Pressure and Cost Transparency in Prescription Choice
Authors: Bouayad Lina , Padmanabhan Balaji , Chari Kaushal
Published: October 2024

This paper presents and synthesizes results from three studies (two controlled experiments and one interview) on using recommender systems to reduce healthcare costs at prescription time, while taking time pressure into account. All of our subjects were real practicing physicians, nurse practitioners, or physician assistants. Across these studies, a total of 160 medical practitioners used a system that provides recommendations for medications along with associated cost information. The main finding was a general tendency among practitioners to reduce healthcare costs by prescribing lower cost medications when cost information is provided by a recommender system. The time pressure faced daily by prescribers, however, appears to impact the use of recommendations by nurse practitioners and physician assistants more than it does physicians. These results have significant implications for cost reduction in healthcare and for the design of effective real-time healthcare recommender systems.

Stable comparisons describing the size of objects in Altai, Khakas and Tuvan heroic tales are considered in comparative terms. Their semantic models are revealed, the components are analyzed: parameter (“size”), standards and objects of comparison. Most of the models (twelve) refer to the large size designation. Only two models of comparisons were identified, indicating the small size of objects. Comparisons with the reference objects of the landscape, mountain and plain describe the size of the most important characters of the epic – the hero and his horse. By comparing the size of animals, the size of objects is determined, which is mainly characteristic of the Tuvan epic. Household items serve as standards for describing both large and small objects; human or animal body parts are mostly small-sized standards. An abstract concept can also be the subject of comparison with the aspects of the “small” and “thin” parameter. The general and specific features of the meaningful structure of comparisons in these languages are determined. Thus, comparisons with components naming objects of the mountain landscape are especially common in the Tuvan epic, they are characteristic of describing the voluminous, rounded muscles of the hero. In the Altai and Khakas legends, on the contrary, the characteristic of the width of the body parts of the hero prevails, and comparisons are used for this, including the names of objects of the plain landscape. The width in the Tuvan epic is described by comparing it with a lake. In Khakas legends, a comparison of the thickness of body parts with trees is noted. A characteristic feature of the Tuvan epic is the numerous comparisons with the standards: the sex and age names of animals. This is also noted in the Yakut epic and is most likely a Mongolian influence. In the languages under consideration, large and small size standards are distinguished in comparisons, which generally belong to the same thematic groups, and the same patterns of determining the size of objects are found. However, the epic of each nation is characterized in many ways by its own set of comparisons.

تعد مدينة سلا من بين أكبر الأقطاب الحضرية المغربية، التي تشهد تحولات مهمة على المستوى السوسيو اقتصادي والعمراني، نتيجة تداخل مجموعة من المتغيرات، مما يطرح عدة تحديات أمام استراتيجيات التخطيط الحضري.  لذلك، تهدف هذه الدراسة إلى الإجابة على إشكالية رئيسية تتمحور حول رصد أنماط التعمير السائدة بالمجال الحضري لمدينة سلا، وإبراز العوامل المتحكمة فيها. لمعالجة الإشكالية المطروحة اعتمدنا المنهج الوصفي، والمنهج التحليلي، والمعطيات الإحصائية التي تم الاعتماد عليها في إنجاز البحث على مستوى ديمغرافية السكان، ومؤشرات البطالة، والفقر، والهشاشة. إلى جانب العمل على معالجة المرئية الفضائية لبرنامج (SASPlanet) للحصول على خرائط تبين أنماط التعمير ومكونات النسيج الحضري بالمدينة، باستثمار نظم المعلومات الجغرافية (SIG). هكذا، بينت النتائج أن أهم ما يميز المجال الحضري لمدينة سلا سيادة نمطين من التعمير، نمط تعمير قانوني، ونمط تعمير غير قانوني يشمل السكن االعشوائي والسكن الصفيحي الذي أصبح السمة التي تميز التعمير بالمدينة، مما يشير إلى انفلات التوجه العام للتعمير من يد أجهزة المراقبة، والذي أعطى في النهاية مدينة ذات مورفولوجية متباينة، بين تجمعات سكنية قانونية وأخرى غير قانونية عشوائية لازالت تطبع المشهد الحضري إلى حدود سنة 2024. وقد خلصت الدراسة إلى أن مدينة سلا تصنف ضمن المدن المغربية الكبرى من حيث النمو الديموغرافي والتوسع العمراني، الشيء الذي أفرز مجالا حضريا متباين النسيج، ساهمت مجموعة من العوامل في جعله السمة والخاصية المميزة لمجموع المجال الحضري. وهكذا، يتخذ التعمير بمدينة سلا في جزء مهم منه طابعا عشوائيا وفوضويا غير خاضع لتخطيط مسبق بنسبة 12.09%، وهذا يحد من فعالية برامج وتدابير التنمية العمرانية.

If we aim to develop efficient synthetic models of protein receptors and enzymes, we must understand the relationships of intra- and intermolecular interactions between hosts and guests and how they mutually influence their conformational ener-gy landscape, so as to adapt to each other to maximize binding energies and enhance substrate selectivities. Here, we intro-duce a novel design of cofacial (ZnII)bisporphyrin cages based on dynamic imine bonding, which is synthetically simple, but at the same time highly robust and versatile, affording receptors composed of only sp2-hybridized C and N atoms. The high structural rigidity of these cages renders them ideal hosts for ditopic molecules that can fit into the cavity and bind to both metal centers, leading to association constants as high as 109 M-1 in chloroform. These strong binding affinities are a consequence of the remarkable chelate cooperativities attained, with effective molarity (EM) values reaching record values of up to 103 M. However, we discovered that the cages can still adapt their structure to a more compact version, able to host slightly smaller guests. Such conformational transition has an energy cost, which can be very different depending on the direction of the imine linkages in the cage skeleton, and which results in EM values 2 to 4 orders of magnitude lower. This interplay between cooperativity and conformational adaptability leads to strong and unusual selectivities. Not only these metalloporphyrin receptors can choose to bind preferably a particular guest, as a function of its size, but also the guest can select which host to bind, as a function now of the host conformational rigidity. Such highly cooperative and selective asso-ciations are lost, however, in related flexible receptors where the imine bonds are reduced.
Viologen-radical-driven Hydrogen Evolution from Water Catalyzed by Co-NHC Catalysts: Radical Scavenging by Nitrate and Volmer-Heyrovsky-like CPET Pathway

The factors controlling the catalytic activity in photochemical hydrogen evolution reaction (HER) are studied in detail for two macrocyclic cobalt compounds bearing two N-heterocyclic carbenes and two pyridyl donors (Co-NHC1 and Co-NHC2, where Co-NHC2 has a methoxy substituent on each pyridyl ligand). The present study adopts an aqueous photosystem consisting of EDTA, [Ru(bpy)3]2+ (bpy = 2,2’-bipyridine), and MV2+ (MV2+ = methylviologen) at pH = 5. Both catalysts are shown to promote HER in a similar efficiency (TON = 12-13 in 6 h), revealing a minor contribution of the electron-donating methoxy substituents. The catalyst degradation is shown to proceed during the photocatalysis, leading to afford [Co(edta)]− (EDTA = H4edta) as a dead-end species. The lack of any heterogeneous species was evidenced by DLS (dynamic light scattering). It was also found that nitrate involved as a counter anion in the photocatalysis components substantially inhibits the photocatalytic HER, giving rise to a large diminishment in TON from 12.7 to 7.2. The Griess test was used to confirm that NO3− serves as a scavenger deactivating the reduced form of MV2+ (i.e., MV+•). The detailed spectroscopic study reveals that the radical dimer (MV+•)2 species plays a key role in promoting the one-step two-electron process: (MV+•)2 + NO3− + 2H+ → 2MV2+ + NO2− + H2O. Our DFT results also reveal that a unique double CPET (concerted proton-electron transfer) pathway is taken to evolve H2 by the Co-NHC catalysts with substantially minimized reorganization energies: Co(II)-NHC → Co(III)(H)-NHC → Co(II)-NHC + H2. This pathway can be viewed as related to the so-called Volmer-Heyrovsky mechanism adopted by some metals and is quite unique to the Co-NHC catalysts.

We present a novel integration of the ANI neural networks into the Amber software suite, offering a sophisticated machine learning/molecular mechanics (ML/MM) framework. The implementation is designed as a general-purpose tool for the simulation of neutral organic molecules, requiring no additional training for its use beyond the initial setup. The framework leverages a new ANI potential that accurately predicts geometry-dependent atomic partial charges at the Minimal Basis Iterative Stockholder (MBIS) level, enhancing the modeling of electrostatic interactions within ML/MM systems. Additionally, we incorporate a polarization correction to address the distortion effects on the ML subsystem from MM point charges. Our approach is validated through simulations of solvation profiles, vibrational spectra, and torsion free energy profiles of small molecules in aqueous environments, as well as protein-ligand interactions. Our findings demonstrate that this ML/MM framework can approximate QM/MM electrostatic embedding with significantly reduced computational demands, paving the way for more efficient and accurate simulations in computational chemistry.

Authors: Ait Ben Lahcen NIZAR
Published: October 2024

Graphene is a one-atom-thick layer of carbon atoms arranged in a two-dimensional honeycomb lattice. Graphene has attracted tremendous attention due to its exceptional mechanical, electrical, and thermal properties. Graphene was considered a ”wonder material” immediately after its discovery because it was deemed capa- ble of bringing drastic changes to many fields. This review gives a comprehensive overview of the atomic structure of graphene, its bonding, and the physical characteristics that have positioned this material as one of the most studied during the past two decades. Further, we discuss recent synthesis techniques including CVD and electrochemical exfoliation and detail the advantages and limitations of each with regard to scalable production. The following review further discusses the vast applications of graphene, from electronics to energy storage, involving production challenges and further improvements that could be achieved in the future. This collection is meant to serve as a starting point for researchers interested in the complications and opportunities brought about by graphene in today’s technologies.
Electronic and optical properties of highly complex Ga2O3 and In2O3 polymorphs using approximate quasiparticle DFT+A−1/2

Published: October 2024

Ga2O3 and In2O3 are promising wide-gap semiconductors for application in trans- parent electronics and ultraviolet optoelectronics. Their pronounced polymorphism leads to varying materials properties with the actual crystal structure. The underly- ing atomic geometries are taken from total energy optimizations within the density functional theory with an appropriate exchange-correlation functional. The precise description of their electronic structures is a challenging task even for the most sophisticated quasiparticle (QP) methods. We apply the fast and efficient but approximate DFT+A−1/2 method to predict fundamental gaps, interband energies and d-level positions of five Ga2O3 and five In2O3 polymorphs in an accurate way, even for polymorphs with 160 atoms in the unit cell. The resulting electronic structures are used to pre- dict dielectric and optical spectra. The resulting effective band masses and dielectric tensors are used to estimate binding energies of band edge excitons. All results are dis- cussed along the polymorph geometry or symmetry and compared with experimental and theoretical data available.
