What should the rules be – or should there be rules? Embodied popular education and the production of facilitated space
Authors: Jolly Aidan , O’ Connor Wendy , Nascimento Cristina Justino do
Published: June 2024

Drama facilitation takes place in “social world” spacetimes that are governed by hegemonic norms. These are created by a complex interplay of global historical processes, the specifics of local factors in the present, and the experience of participants. In Merseyside, UK, these processes create intersectional oppression, which, despite a rhetoric of “inclusion,” renders engagement in creative work either uncomfortable or unobtainable for diasporic and working-class communities in the area. These communities also continue to disproportionately experience various forms of violence. Our response is a trauma-informed “conscientization through the body,” using an eclectic mix of emergent methodologies that intentionally co-create emancipatory spacetimes.
Populism in Argentina: Crisis of the Dominant Ideology and Transformation of Political Course
Authors: Silokhina A. S.
Published: June 2024

The article analyzes the current populist dynamics in Argentina. The first part is devoted to the key interpretations and features of populism as a political phenomenon. Due to the lack of consensus in the conceptualization of the phenomenon and the wide variety of interpretations, its main features are singled out. Special attention is paid to the economic, political and ideological causes and consequences of the current crisis of Peronism, which has been the dominant political force in Argentinean politics for many decades. It is noted that the current crisis in ideology was the result of specific political trends emerged in the country on the eve of the presidential elections in the fall of 2023. In addition, the author deals with the domestic and foreign policy course of the incumbent government and the intermediate results of the policies pursued. At the end of the article, the populist nature of the current course is also explained.
Russian Advancement in Central Asia in the Works of Russian Lieutenant-General and Orientalist M.A. Terentyev
Authors: Podberezkina O. A.
Published: June 2024

Mikhail Afrikanovich Terentyev was a Russian lieutenant general, military orientalist and historian, linguist, lawyer, who 150 years before the current events described geopolitics in Central Asia, the relations between Russia, England, Persia, and Muslim states, which still remain as controversial and complex as they were in the XIX century. He was surprisingly accurate in his assessment of the importance of public opinion in England and its press, so that Russia should have been careful when its power was exaggerated. The same image of Russia as an extremely strong and immoderate in appetite rival is persistently imposed by the British press on its society today, as well as on Europeans and Americans. He very accurately foreshadowed Russophobia and showed how members of the British parliament set tasks for the press and how the “sixth great power” worked. In his writings on Central Asia, M.A. Terentyev took into account economics, politics, military, individual qualities of leaders, public opinion, culture, language and national peculiarities. His writings shed light on the interdependencies and politics of states and there is no doubt that researchers will continue to refer to his works in the future. This article offers the reader useful remarks by M.A. Terentyev from his major works: “Russia and England in the Struggle for Markets” and “Russia and England in Central Asia”, which were highly appreciated in Russia, England and Europe. They shed light on the world economy and politics of the XIX century: the importance of cotton at the time to the world market, the importance of Central Asia to England, and they even link the assassination of Paul I to Russia’s attempt to control the route to India.

Theoretical Issues on Crime Prevention
Authors: Hai Nguyen Khac
Published: June 2024

Crime is a complex, diverse and constantly changing phenomenon. Crime prevention strategies, programs and measures selected for a nation or community should be compatible with the limited resources of that society to ensure effectiveness. Therefore, awareness and prediction of crime phenomenon, the identification of the desired prevention effect, and the expansion of prevention initiatives both in the public and private sectors to control it are essential. In addition, this study opens up new avenues for research in Vietnam and offers a variety of approaches to categorize and systematize crime preventive actors and institutions. The article also analyzes the basic principle underlying the guidelines for crime prevention. Based on the theoretical issues that have been resolved, the article suggests further research directions in Vietnam.
The Validity of Standard Clauses in E-Commerce: The US Experience and Suggestions for Vietnam
Authors: Thu Phuong Tran Thi
Published: June 2024

Consumers tend to participate more and more in e-commerce transactions. When participating in these transactions, in many cases, consumers will sign and implement standard terms. The validity of the standard clauses is always an issue of interest to researchers, especially when they contain provisions on governing law and jurisdiction. So, how is the legal effect of these provisions determined in practice? Using the comparative method and the approach to typical cases resolved by US law, this article focuses on the above-mentioned issues but is limited to the content related to the contracting process without commenting on the clauses. As a result, the article proposes solutions for improving Vietnamese law.
Improving the Legal Provisions on Initiating Cases at Victim’s Request: Recommendations from the Criminal Procedure Laws of Russia and China
Authors: Son Mai Thanh
Published: June 2024

Initiating criminal cases at the victim's request is a relatively special provision in Vietnamese criminal procedure, adopted to protect and enhance the victim's rights. However, this provision in the Criminal Procedure Code 2015 still contains some unreasonable points. Meanwhile, Russia and China - two countries with significant similarities and influences on Vietnam's legislative process - have advanced provisions to enhance the victim's position in the criminal procedure law, particularly from the stage of initiating criminal proceedings.  The article utilizes synthetic, analytical, and comparative methods to analyze the legal provisions surrounding the initiation of criminal proceedings at the victim's request in Vietnam and the two countries above. Based on this, the article proposes amendments to Article 155 of the Criminal Procedure Code 2015 and several recommendations to improve the victim's position while protecting their legal rights and interests when participating in criminal proceedings.
Responsible Business Practices and Legal and Practical Issues in Corporate Governance and Investment in Vietnam
Authors: Thanh Thuy Phan Thi
Published: June 2024

Responsible business practices (RBP) is a national and global strategy, but it is not a completely new concept in the world and in Vietnam. It is the proactive development and practice of corporate social responsibility (CSR) nationally and internationally. Accordingly, RBP is to promote enterprises to comply with the law, respect people's interests, and protect the environment and social benefits. In Vietnam, except for the domestic enterprises in the partner network of large foreign corporations, the awareness and practice of CSR have not become a popular movement among small and medium-sized enterprises. Therefore, in parallel with building a comprehensive and mandatory business legal framework, education to raise the awareness and practice of CSR for domestic enterprises would create a suitable environment for ensuring RBP in the Vietnam.
Between Laborer and Slave
Authors: Anatona Anatona
Published: June 2024

Broadly speaking, both laborers (or coolies) and slaves served as manual workers engaged in arduous physical tasks. However, distinctions arise not only from the historical origins of these terms but also from their definitions and conceptual frameworks. Key differences between laborers and slaves pertain to social status, identity, rights and obligations, interpersonal relationships with employers, and the nature of treatment received. Despite these fundamental differences, the practical reality often diverged. There are instances where laborers or coolies were treated in ways akin to slaves. This article aims to discuss and examine the extent to which such treatment was experienced by plantation workers in the Dutch colonial era, known as contract coolies, in the East Sumatra region. The issue is reconstructed and analyzed through a historical lens, spanning the late 19th to early 20th centuries, marked by the establishment of plantation centers in the Dutch East Indies by foreign entrepreneurs, including those in East Sumatra. Examination of available historical sources reveals that a portion of these contract coolies endured harsh and inhumane treatment, mirroring the experiences of slaves in various other contexts.

Published: June 2024

This research was undertaken to enhance the efficiency of sawdust briquette using mung beans waste. Mung beans waste (MB) was blended with sawdust briquette to investigate the effect on the mechanical properties (hardness, porosity index, durability, compressive strength, bulk density and mass). Prior to the blending of the sawdust and mung beans waste, proximate analyses (moisture content, fixed carbon, ash content, volatile matter content and calorific value) were carried out on the mung beans waste and the sawdust to ascertain their suitability for biofuel production. The analyses were carried out using standard methods. The briquettes were produced at different sawdust to biomass ratios (100%:0%, 70%: 30%, 50%:50%, 30%:70% and 0%:100%) using cassava starch binder. The result of the analysis shows that the moisture content was 7.1796±0.00% for mung beans waste and 31.479±0.00 for the sawdust. Ash content was 8.25±0.002% for mung beans waste and 1.070±0.001% for the sawdust. The volatile matter was 16.610±0.01%) for sawdust and 22.976±0.00% for mung beans waste.The fixed carbon content of the sawdust was (50.841±0.00%) and 61.57±0.00% for mung beans waste.The calorific value was 18.60MJ/kg for mung beans waste and 20.30MJ/kg for the sawdust. The mass of the briquette increased with an increase in biomass load, ranging from 44.1±0.01 (70% sawdust and 30% biomass) to 61.1±0.90 (100% biomass). The bulk density of the sawdust briquette increased with increase in biomass load ranging from 0.234±0.00 g/m3 (70% sawdust+ 30% biomass) to 0.421±0.007 g/m3 (100% biomass). Hardness of the sawdust briquette increased with increased in biomass load with value ranging from 366±0.57 (70% sawdust + 30% MB) to 394±0.00 (100% MB). The porosity of the briquette decreased with increased in biomass load ranging from 0.20±0.01 (100% MB) to 0.97±0.01 (30% MB + 70% sawdust). The durability of the briquettes decreased with increase in biomass load ranging from 0.89±0.00 (70% sawdust + 30% biomass) to 0.79±0.01 (100% biomass). The compressive strength of the briquettes increased from 70% sawdust + 30% biomass (2.78±0.01 N/mm2) to 30% sawdust + 70% biomass (3.42±0.38 N/mm2) before decreasing at 100% biomass (2.44±0.02 N/mm2). It can be concluded that Mung beans waste can effectively enhance the efficiency of sawdust briquettes by improving the mechanical properties.

Ice Shape Convergence in Multistep Ice Accretion Simulations
Authors: Donizetti Alessandro , Bellosta Tommaso , Guardone Alberto
Published: June 2024

Local errors in the geometrical description of the ice front are amplified in multistep simulations over conformal meshes due to the coupling of aerodynamics, water impingement, ice accretion, and grid deformation. Small perturbations in the initial phase of ice formation possibly result in dramatically different ice shapes, which can hinder the stability of the multistep procedure. This problem is analyzed by investigating the combined effects of space and time discretization on the ice growth over airfoils and three-dimensional wings. We propose an automatic procedure for selecting the time interval for the update of the aerodynamics and particle impingement. A local growth limiter [Formula: see text] is introduced here to bound the local ice thickness growth to be comparable to the local grid spacing on the surface, resulting in an automatic adaptive time step to be used in the multistep simulation. Examples are provided for three-dimensional cases under both rime and glaze conditions over straight and swept wings. These examples highlight the different accretion mechanisms of the two ice regimes and preliminarily indicate that ice-shape convergence can be achieved for low values of [Formula: see text].
Pragmatic and Semantic Parameters of Linguistic and Discursive Creativity in Advertising
Authors:   Institute of Linguistics of the Russian Academy of Sciences Moscow, Russian Federation, Sokolova O.V.
Published: June 2024

The article investigates advertising discourse in terms of linguistic creativity. The analysis undertakes on the basis of functional and communicative-discursive approaches. The characteristic of advertising is the dominance of appellative function and the orientation towards the drawing of the addressee’s attention with the help of linguistic means of deviation from the language norm. Considering that structural deviation is considered to be a “norm” for advertising, we explore linguistic creativity on the basis of semantics and pragmatics. The paper enumerates and draws upon the basic parameters of linguistic pragmatic and semantic, which are characteristic of advertising discourse.
Optimization of the surgical approach to treating hepatic cystic echinococcosis: A retrospective observational non-randomized study
Authors: Boyarinov V. S. , Rogal M. L. , Novikov S. V. , Dzhagraev K. R. , Yartsev P. A.
Published: June 2024

Background. Hepatic echinococcosis poses a great threat to human health and life. In order to minimize the risk of disability and speed up the postoperative recovery process, it is necessary to make an informed choice of the surgical treatment approach to be used. However, it is still unclear when traditional surgical methods should be applied and when less traumatic, minimally invasive, ultrasound-guided interventions can be used. This is what prompted this study. The article presents the results of using different surgical methods to treat patients with hepatic echinococcal cysts.

Aim. To improve the outcomes of treating patients with hepatic cystic echinococcosis by optimizing the surgical approach using percutaneous minimally invasive and traditional surgical interventions.

Methods. A non-randomized comparative study was conducted at the Sklifosovsky Institute for Emergency Medicine of the Moscow Department of Health. The subjects were treated in 2010–2020, with a follow-up period of four years after surgical treatment. A total of 78 patients with hepatic echinococcal cysts aged 18 to 78 years were treated. At the preoperative stage, medical history was collected from all patients, including data on migration during life. The diagnosis of all patients was confirmed through laboratory tests, instrumental methods (computed tomography and ultrasound), and a morphological examination of surgical material. All patients were divided into four groups: three groups of patients treated using different percutaneous minimally invasive methods and a comparison group of patients who underwent traditional surgery. The systematization of the material and its primary mathematical processing were performed using Excel 2016 (Microsoft, USA). The obtained numerical data were processed via methods of mathematical statistics using IBM SPSS Statistics 26 Version (IBM, USA).

Results. In the sample distribution of the studied groups by gender, age, as well as the number of cysts and concomitant diseases, no statistically significant differences were identified; however, the study yielded several results indicating the advantages of using minimally invasive treatment for hepatic echinococcal cysts. In spite of the high likelihood of biliary fistulas and a suppurative residual cavity occurring with the use of minimally invasive methods, a statistically significant reduction in the operation time, duration of anesthesia in the postoperative period, and blood loss were observed, which in turn reduced the stay in the inpatient surgical facility.

Conclusion. Minimally invasive methods can be used in all types of hepatic echinococcal cysts, as well as traditional surgery. It is reasonable to perform minimally invasive interventions if the clinic is adequately equipped and the surgeon is experienced in minimizing postoperative complications and recurrences.

Published: June 2024

The influence of the initial concentration, rate and temperature of adsorption on the adsorption separation of gas mixtures (CO2, CH4, N2, H2S) is investigated. Components: N2 – 5%, H2S – 5%, CO2 – 5% and CH4 – 85%. And as an adsorbent granule of clinoptilolite of irregular shape were used. Isothermal adsorption of CO2 was obtained at different temperatures (293, 313, and 323 K). The obtained isotherms of CO2 adsorption showed that with an increase in temperature, the adsorption of CO2 decreased. The type of isotherms corresponds to Langmuir. The output curves of gas mixture adsorption depending on the gas flow rate and various main components of CO2 were also experimentally studied. The output curves of the adsorption of the CO2 component were studied at various gas flow rates of 20, 50, and 80 mL/min. Equilibrium time increases with a decrease in the gas flow rate. Output curves were also obtained depending on the initial CO2 concentrations of 5%, 10% and 20%. It was determined that with a decrease in the initial concentration of CO2, the equilibrium time also increases. Gas mixture components sorbed downwards: H2S→CO2→CH4→N2. The resulting system of model equations describing the adsorption separation of gas mixtures in a fixed adsorbent layer represents a complete mathematical model of the process under unsteady conditions. The obtained regularities of the process of adsorption of gas mixtures testify to the fact that the process takes place under non-stationary conditions. The proposed models for the optimal design of industrial absorbers can be used for adsorption separation of gas mixtures in the conditions of their unsteady flow.

The species composition of soil diatoms in Frolikhinsky State Nature Reserve was studied. Flora of diatoms algae was represented with 128 taxa of 4 classes, 12 orders, 23 families and 49 genera. The greatest diversity of species was found on the bank of the Bireya River (77 species), and the lowest – on the Barguzinsky ridge pass (3 species). In most species and intraspecific taxa of diatoms (97%) found in the reserve, the occurrence rate varied from 10 to 40%. An occurrence rate above 40% was noted only in four taxa that were identified as leading: Pinnularia borealis (80%), Adlafia bryophila (50%), Gomphonema parvulum (50%) and Planothidium lanceolatum (50%). The complex of dominant species was diverse and included representatives of 15 families. 36 species and intraspecific taxa were classified as dominants, 20 taxa were classified as subdominants. The complex of associated species included 6 taxa, 67 taxa were found singly and occasionally. Pinnularia borealis Ehrenberg had the highest occurrence at all sites. The families Fragilariaceae, Achnanthidiaceae, Naviculaceae, Ahnanthaceae, Gomphonemataceae, Cymbellaceae, Cocconeidaceae, Eunotiaceae, Pinnulariaceae, Bacillariaceae, Sellaphoraceae were characterized by high species diversity. Comparison of diatoms complexes (DC) in different plots of the reserve revealed similarities and differences of floristic diversity and taxonomic structure. The main reasons of taxonomic heterogeneity of DC in different areas are the conditions defined by their location within the natural reserve. The largest number of species was found on the shores of water bodies characterized by a high degree of moisture. The least abundant and diverse diatoms were represented in shaded and insufficiently moist areas of coniferous forests with abundant coniferous litter and acidic soils.

During our study, we identified the most frequent risks factors for developing low back pain during pregnancy, as well as the benefits of performing rehabilitation techniques and physiotherapy during the latter stages of pregnancy. Rehabilitation techniques and physiotherapy are still not enough explored in obstetrics, as they can prove to be an important asset in boosting pregnant women’s quality of life, as well as in preparing them for delivery.

Objective. This study was designed to analyze the dele­te­rious effect of endometriosis on ovarian reserve after sur­ge­ry by studying anti-Müllerian hormone (AMH) levels. Mate­rials and method. This is a systematic review that included observational studies and randomized clinical trials published in English between 2015 and 2019. We in­clu­ded 17 studies that reported AMH levels in patients un­der­going laparoscopic surgery for endometrioma, mea­sured preoperatively and postoperatively. Results. Seventeen stu­dies met the inclusion criteria. A significant decrease in AMH levels was observed in the short-, medium- and long-term postoperative periods compared to baseline AMH levels. However, there were no differences between post­ope­ra­tively immediately and one year after surgery. Post­ope­ra­tive AMH levels were significantly reduced in bi­la­te­ral endometriomas compared to unilateral cases. Also, patients with endometriomas, compared to patients with other benign ovarian conditions, had a more important de­cline in AMH levels. The same was observed in cases of bi­la­te­ral cystectomy compared to vaporization with bipolar ener­gy or laser. A greater decrease in postsurgical AMH was also observed with bipolar energy hemostasis compared to su­ture and hemostatic agents. Conclusions. Endometrioma sur­gery has a negative effect on postoperative AMH levels. Bila­te­ral endometriomas and those greater than 7 cm are associated with a significant decrease in AMH. The mecha­ni­cal removal of healthy tissue and the destruction of the ova­rian cortex may explain the reduction in ovarian reserve.

Human papillomaviruses (HPVs) are responsible for ap­pro­xi­ma­tely 5% of all cancers, with high-risk types causing nearly all cervical cancer cases. While cervical cancer is the most recognized outcome of HPV infection, the virus also con­tri­butes to vulvar, vaginal, penile, anal, and head and neck can­cers. HPV types 16 and 18 are the primary culprits in these malignancies. HPVs exhibit strict host specificity and en­com­pass over 100 types, some linked to benign conditions like genital warts. The viral oncoproteins E6 and E7 play a crucial role in cancer development by inhibiting tumor sup­pressor genes. HPV-related diseases manifest in various ways, from common conditions like anogenital and plantar warts to rare presentations such as recurrent respiratory pa­pil­lo­ma­to­sis, conjunctival papillomas, and middle ear car­ci­no­mas. The clinicians must recognize this diversity to en­sure the accurate diagnosis and management. Preventive mea­sures, particularly large-scale vaccination, are essential to reduce the incidence and complications of HPV-related diseases.

Endodontic treatments during pregnancy can be safely performed taking certain precautions. The aim of this cli­ni­cal case, which we present in our article, was to treat an ir­re­ver­sible pulpitis in a second-trimester pregnancy patient who was undergoing an orthodontic treatment prior to pregnancy. The endodontic treatment was performed with­out removing the facial arch and brackets, in a single ses­sion, using multiple waves condensation method. The en­do­don­tic technique of vertical hot condensation used has the advantage that it can fill the entire root system three-di­men­sio­nally. After one week, the coronal restoration was made with resin composites. Teeth that are included in an or­tho­dontic treatment can be adequately endodontically treated and coronally restored during pregnancy.

This study investigates the effect of selection attributes of convenience store PB products on Generation MZ's satisfaction and repurchase intention. For this research objective, a survey was conducted using the convenience sampling method among MZ generation customers with experience purchasing convenience store PB products nationwide. For a limited period of 15 days, the frequency analysis of the Google online survey method was used to find out the demographic characteristics of the survey population, and the validity and reliability of the measurement tool were verified by principal component analysis using the SPSS statistical program. Finally, simple regression and multiple regression analyses were conducted to test the hypotheses, and the hypothesis testing results of this study are as follows. First, among the selection attributes of convenience store PB products, brand, packaging, quality, and price positively affect satisfaction. Second, satisfaction has a positive effect on repurchase intention. Third, selection attributes such as brand, packaging, quality, and price of convenience store PB products positively influence repurchase intention. Regarding academic and practical implications, the selection attributes were applied to the MZ generation who purchase PB products. It is recommended that PB products be continuously launched as trends change according to new consumer preferences. The results show that if MZ continues to research and develop ideas for convenience store PB products that consumers are interested in, it will be able to sell products that are differentiated from competitors' convenience stores.

Carbon dioxide utilization presents an important and topical research topic. However, the performance of catalysts needed for CO2 transformations does not achieve the necessary levels for their widespread application. To this end, we decided to study non-aqueous condensations providing amine-functionalized silica catalysts, possibly active in CO2-epoxide cycloaddition reaction. While non-hydrolytic sol-gel method is well-known for its efficiency in providing highly porous Lewis and Brønsted acid metallosilicates, here we show for the first time its application for the preparation of silica-based catalysts containing basic groups. First, the reaction conditions were screened to reproducibly obtain porous materials with preserved amine moieties. These were identified as follows: silicon tetraacetate and bridging tertiary amine silanes as precursors, toluene as a solvent, and temperature between 160 and 180 °C. In such a way, materials with up to 776 m2 g−1 and 1.58 cm3 g−1 were obtained in one-step process, without any template, after conventional drying step. Next, the amine-functionalized materials were tested in CO2-epoxide coupling providing cyclic organic carbonates with high selectivity (>99 %) and moderate activity (up to 86 % epichlorohydrin conversion after 1 h at 120 °C and 10 bar CO2). The characterization of spent catalysts revealed a presence of cyclic organic carbonates at the catalyst surface as well as conversion of tertiary amine groups to quaternary ammonium moieties.
Lattice Models in Molecular Thermodynamics: Merging the Configurational and Translational Entropies
Authors: Åstrand Per-Olof , de Miguel Rodrigo
Published: June 2024

Lattice models are a central idea in statistical thermodynamics, as they allow for the introduction of a configurational entropy by counting the multiplicity of placing indistinguishable particles on a lattice. In this work we use a lattice model to show that the configurational entropy needs to be merged with the molecular translational entropy in order to have a consistent model. This is achieved by replacing the volume of a lattice site with a quantum volume (i.e., the cube of the thermal wavelength). This modified lattice model allows us to derive a new equation of state, referred to as the Bragg-Williams equation state, from which we may also derive a generalized version of the van der Waals equation of state. In contrast to the standard van der Waals equation of state, the heat capacity of the new models has temperature dependence.
Ab initio Spin-Mapping Non-adiabatic Dynamics Simulations of Photochemistry

Published: June 2024

We perform on-the-fly non-adiabatic molecular dynamics simulations using the recently developed spin-mapping formalism. Two quantum dynamics approaches based on this mapping formalism, (i) the fully linearized spin-LSC and (ii) the partially linearized spin-PLDM, are explored using the quasi-diabatic propagation scheme. We have performed dynamics simulations in four \textit{ab initio} molecular models for which benchmark \textit{ab initio} multiple spawning data has been published. We find that the spin-LSC approach routinely outperforms the spin-PLDM approach and yields a roughly equivalent accuracy to the previously reported symmetric quasi-classical approach. We further explore the underpinnings of the spin-PLDM correlation function by decomposing its various contributions stemming from its summation over all the terms, $N^2$, in the density matrix-focused initial conditions where $N$ is the number of states in the quantum subsystem. Finally, we found an approximate form of the spin-PLDM correlation function that simplifies the simulation and reduces the computational costs from $N^2$ to $N$.

Published: June 2024

Aryl rings appear in a plethora of natural products or drugs. A vast majority of arylation processes still rely on the utilization of transition-metal complexes as catalysts. Another important strategy for introducing aryl rings into an organic skeleton operate through a radical pathway. The chemistry of aryl radicals has witnessed rapid development during the last century, especially as these species are crucial intermediates in many synthetically-meaningful organic transformations, such as the Sandmeyer or Pschorr reactions. Predominately, they are prepared employing conventional redox reagents (oxidants or reductans) that are often used in large excess. In turn, recent developments in photocatalysis and synthetic electrochemistry allow for the assembly of Ar• species in a more sustainable and straightforward way, however, these advancements have not been timely and critically summarised so far. This Review fills this obvious gap and sum up recent advances in processes involving Ar• by highlighting some challenges and identifying potential areas of improvement, which might inspire future research endeavors in this topic.
Exploring Novel Quantum Embedding Methods with a Non-orthogonal Decomposition of Slater Determinants
Authors: Ai Yuhang , Jiang Hong
Published: June 2024

The Schmidt decomposition of quantum many-body states, which is the basis of many powerful quantum many-body techniques, relies on a partition of the whole system in terms of orthogonal local basis functions. By carefully investigating the spectrum of the truncated density matrices in a non-orthogonal basis, we propose in this work a non-orthogonal decomposition of Slater determinants, which reduces to the conventional Schmidt decomposition in the orthogonal limit. The new decomposition provides a natural tool for building local correlation spaces when the orbitals are overlapping, and we are able to extend some existing embedding methods based on the Schmidt decomposition like density matrix embedding theory (DMET) to overlapping subsystem partitions to achieve greater flexibility and efficiency. We also propose a new quantum embedding strategy as another utility of the non-orthogonal decomposition that bridges the \textit{ab initio} model potential (AIMP) theory and DMET, which does not require a mean-field calculation of the whole system like AIMP, and is able to capture quantum entanglement like DMET.
Telomerase Reverse Transcriptase Degradation via a Rationally Designed Covalent Proteolysis Targeting Chimera
Authors: Frost Grant , Liu Yue , Kron Stephen , Scheidt Karl
Published: June 2024

Expression of telomerase reverse transcriptase (TERT) is a hallmark of cancer, maintaining telomere length and integrity to enable replicative immortality. However, TERT also serves multiple enzyme-dependent and -independent functions to support cell growth and survival, including enhanced DNA damage response. Agents that inhibit TERT reverse transcriptase activity prevent telomere elongation but may fail to limit other TERT functions that mediate cancer therapy resistance. Thus, we applied structure-based design, modular synthesis, and biochemical assays toward developing a proteolysis targeting chimera (PROTAC) to drive proteasomal degradation of TERT in cancer cells. This yielded NU-PRO-1, a PROTAC linking the TERT active site-targeted covalent inhibitor NU-1 to the VHL E3-ligase ligand (S,R,S)-AHPC. Applied to cancer cells, NU-PRO-1 induced transient VHL- and proteasome-dependent TERT degradation. NU-PRO-1 did not induce DNA damage on its own but acted to further delay DNA repair after irradiation compared to NU-1. TERT-degrading PROTACs provide novel chemical probes of TERT's non-catalytic functions and may overcome the limitations of current telomerase inhibitors as cancer therapeutics.
