Elastic flow of curves with partial free boundary
Authors: Diana Antonia
Published: October 2023

We consider a curve with boundary points free to move on a line in $\R^2$, which evolves by the $L^2$--gradient flow of the elastic energy, that is a linear combination of the Willmore and the length functional.For such planar evolution problem we study the short and long--time existence. Once we establish under which boundary conditions the PDE's system is well--posed (in our case the Navier boundary conditions), employing the Solonnikov theory for linear parabolic systems in H\"older space, we show that there exists a unique flow in a maximal time interval $[0,T)$. Then, using energy methods we prove that the maximal time is actually $T= + \infty$.

Published: October 2023

Mining and smelting sectors contribute significantly to global growth on a regional and local scale. However, the operations are causing significant environmental damage, particularly pollution of the soil with potentially toxic metals (PTMs).  In this study, the speciation of PTMs (arsenic, cadmium, chromium, mercury, manganese, nickel, lead and zinc) from the mine impacted soils of Riruwai mining area was investigated using a modified Tessier sequential extraction method. The findings of the study revealed that all the PTMs examined are considerably associated with non-residual fractions in all the sampling locations. This indicates that all the PTMs investigated in the study area may be highly mobile in the soils and hence potentially toxic. The concentrations of PTMs in the soil’s geochemical fractions were found to vary with the sampling locations, with active mining sites significantly (p ≤ 0.05) recording the highest value, followed by farmland, while the lowest value was reported at the control site. Therefore, to protect the environment and the health of the local populace, PTMs in the soils of the study area should be regularly monitored and a treatment program should be put in place.

Authors: Suryandari Ervin Tri , Abdul Keyon Aemi Syazwani
Published: October 2023

Bamboo charcoal from four types of Indonesian bamboo species had been successfully prepared and characterized. The yield was 19.67%; 30.86%; 33,16% and 27,34 respectively for Apus bamboo, Javanese bamboo, Ori bamboo and Yellow bamboo. The activation of bamboo charcoal was carried out chemically using KOH and H3PO4. Activated bamboo charcoal was characterized for the content of water, volatile substance, total ash, and carbon, as well as iodine absorption capacity based on the technical standard of activated carbon SNI 06-3730-1995. The activated bamboo charcoal was also characterized using Fourier Transform Infrared (FTIR) to determine the functional groups, SEM to determine morphology and nitrogen adsorption desorption to determine the surface area. The activation process was able to reduce water, ash, volatile substance content; thereby increasing carbon content which has the potential to be used for adsorption, and this is evidenced by the increase in the value of iodine absorption. From the FTIR data activated bamboo charcoal shows the presence of a C=O at 1500-1600 cm-1, O-H at 3400-3500 cm-1 and CO at 1300-1400 cm-1 which has the potential to contribute the active site for adsorptionprocess. Based on SEM data the morphology of activated bamboo charcoal was porous. Enhance quantity of pores would increase the surface area and the adsorption ability. From the results of the surface area data, it was found that the 4 types of activated bamboo charcoal produced a higher surface area, and activation using KOH was more effective than H3PO4in increasing the surface area of activated bamboo charcoal.

Published: October 2023

The increasing incidence of metabolic diseases, including obesity and diabetes,
is a serious social public problem. Therefore, there is an urgent need to find effective
prevention and treatment measures for these diseases. DsbA-L is a protein that is
widely expressed in many tissues and is closely related to metabolism. Emerging evidence
shows that DsbA-L plays an important role in antioxidative stress, promoting the
synthesis and secretion of adiponectin and maintaining mitochondrial homeostasis, and
the abnormalities of these functions are also closely related to the occurrence and development
of metabolic diseases. Here, we reviewed the tissue expression patterns and regulatory
factors of DsbA-L, summarized its biological functions and the current research
progress of DsbA-L in metabolic diseases, and found that DsbA-L may be a promising
target for metabolic diseases.

Allergist-cardiologist Interdisciplinary Point of View
Authors: Calogiuri Gianfranco , Savage Michael P. , Congedo Maurizio , Nettis Eustachio , Mirizzi Alessandro Mandurino , Foti Caterina , Vacca Angelo , Kounis Nicholas G.
Published: October 2023

Worldwide, adrenaline is considered the first choice therapy in the international guidelines for the
management of anaphylaxis. However, the heart and cardiovascular apparatus are strongly involved in anaphylaxis;
for that reason, there are some cardiac conditions and certain anaphylaxis patterns that make epinephrine
use problematic without adequate heart monitoring. The onset of Kounis syndrome, takotsubo cardiopathy, or
the paradoxical anaphylaxis require great attention in the management of anaphylaxis and adrenaline administration
by clinicians, who should be aware of the undervalued evolution of anaphylaxis and the potential cardiologic
complications of epinephrine administration. Numerous case reports and studies describe the unexpected
onset of cardiac diseases following epinephrine treatment, despite the latter being the recommended therapy
for anaphylaxis. Our review suggests that future anaphylaxis guidelines should incorporate cardiovascular specialists
since the treatment of Kounis syndrome or takotsubo cardiopathy requires cardiologist skills.
A Review on Traditional and Modern Methods for the Synthesis of Aromatic Azo
Compounds
Authors: Patel Ashok Raj , Patel Geetika , Srivastava Arti , Banerjee Subhash
Published: October 2023

Aromatic azo compounds are “derivatives of diazene/diimide”, wherein the two hydrogens are substituted by phenyl groups. Azo compounds are very important universal scaffolds that show multiple applications
in many areas of science, mainly chemical industries, where they are used in the synthesis of organic dyes, pigments, food additives, indicators, etc. They also remarkably exhibit various potential applications in the fields of
pharmaceuticals, electronics, optics, etc., because of their fascinating photophysical properties. Moreover, several azo compounds have been strongly utilized as chemosensors, diagnostic probes, radical initiators, nanotubes,
and building blocks of various polymers as well as natural products. This interesting and immense importance of
the azo compounds has attracted the attention of researchers to establish novel synthetic routes to synthesize
these important scaffolds. In organic chemistry, azo compounds can be synthesized by various methods utilizing
coupling reactions with the aid of a catalyst or sometimes in the absence of it. The main purpose of writing this
review was to provide a summary of the synthesis of both symmetric and asymmetric azobenzenes via various
traditional and recently developed oxidative aza-coupling reactions.
Dimeric Calix[4]arenes, Synthesis and their Application: A Review
Authors: Zadmard Reza , Khosravani Sara , Jalali Mohammad Reza
Published: October 2023

Calix[n]arene is an attractive host for molecular recognition due to its accessibility through the hollow cavity and shallow bowl shape and has been used as a receptor over the last 30 years. Calix[n]arene has a
small cavity, so designing a flexible molecule to recognize nano to large biomolecules is a challenging goal in
host-guest chemistry. Dimeric calix[n]arene is formed by linking two calix[n]arene sub-units to each other.
Their considerable structural features and relative diversity of modifying the upper or lower rim represent outstanding and greatly adaptive structures for designing bulky and complex building blocks adequate for selfassembly and molecular recognition. Their ability to form supramolecular structures for a wide range of applications, including the recognition of nano-molecules and large biological molecules, has been extensively studied. This review details the progress of the host-guest chemistry of dimeric calix[n]arenes, emphasizing the synthetic pathways employed for their production and their self-assembly properties. Dimerization of calix[n]arene
occurs in two ways (1-through non-covalent bonding such as H-bonding or self-assembly, and 2-through covalent bond formation such as amide bond formation, multi-component reactions and Sonogashira cross-coupling
reaction and metathesis reactions). In this work, we focused on dimerization through covalent bond formation,
due to having more applications and diverse synthetic applications.

Published: October 2023

Background:

Dysferlinopathies represent a group of limb girdle or distal muscular dystrophies with an autosomal-recessive inheritance pattern resulting from the presence of pathogenic
variants in the dysferlin gene (DYSF).

Objective:

In this work, we describe a population from a small city in Brazil carrying the
c.5979dupA pathogenic variant of DYSF responsible for limb girdle muscular dystrophy type 2R
and distal muscular dystrophy.

Methods:

Genotyping analyses were performed by qPCR using customized probe complementary
to the region with the duplication under analysis in the DYSF.

Results:

A total of 104 individuals were examined. c.5979dupA was identified in 48 (46.15%) individuals.
Twenty-three (22%) were homozygotes, among whom 13 (56.5%) were female. A total of
91.3% (21) of homozygous individuals had a positive family history, and seven (30.4%) reported
consanguineous marriages. Twenty-five (24%) individuals were heterozygous (25.8±16 years) for
the same variant, among whom 15 (60%) were female. The mean CK level was 697 IU for homozygotes,
140.5 IU for heterozygotes and 176 IU for wild-type homo-zygotes. The weakness distribution
pattern showed 17.3% of individuals with a proximal pattern, 13% with a distal pattern and
69.6% with a mixed pattern. Fatigue was present in 15 homozygotes and one heterozygote.

Conclusion:

The high prevalence of this variant in individuals from this small community can be
explained by a possible founder effect associated with historical, geographical and cultural aspects.

Pharmacological Potential of Sulindac and Its Active Metabolite: A
Comprehensive Review
Authors: Gupta Shraddha Manish , Behera Ashok , Singh Siddharth
Published: October 2023

:

In this review, we describe and discuss the pharmaceutical aspects, pharmacokinetic profile,
and preclinical and clinical studies of sulindac and its active metabolite and emphasise their
potential activity not only in anti-inflammation strategies but also as chemoprevention drug candidates.
Though they are widely validated through in vitro and in vivo models, to date, no efforts have
been made to compile in a single review on their pharmacologically potential, pharmacokinetics and
toxicity profiles. Key databases such as PubMed, Science Direct, Scopus, and Google Scholar, among
others, were probed for a systematic search using keywords to retrieve relevant publications. An exhaustive
electronic survey of the related literature on the pharmacologically potential activity and the
pharmacokinetic and toxicity profiles of sulindac resulted in around 200 articles (1975 and 2023)
being included. The studies conducted on sulindac sulphide and sulindac sulfone metabolites reported
a varied range of biological effects deployed in this review. The review concluded that there is scope
for repurposing sulindac using computer-aided drug design and biological study to find out possible
new targets for strengthening the potency and selectivity of the metabolites.

Authors: Alam Farid , Singh Jitendra , Kumar Nilesh , Kumar Kailash , Dinkar Anju
Published: October 2023

Introduction:

Gaucher's disease (GD) is a rare lysosomal storage disease. It is characterized
by the deposition of glucocerebroside in cells of the macrophage-monocyte system. GD
presents a broad clinical expression, including hematologic abnormalities (such as pancytopenia),
massive hepatosplenomegaly, diffuse infiltrative pulmonary disease, renal involvement in
the form of nephropathy and glomerulonephritis, skeletal involvement in the form of bone pain,
bony infarct, osteopenia, and pathological fracture. Based on the presence or absence of neurologic
involvement, it is differentiated into type 1, type 2, and type 3. Gaucher’s disease type 1 is
the most common form, having the nonneuropathic form and carrying autosomal recessive traits.
Gaucher's disease affects all racial and ethnic groups, while type 1 GD is most prevalent among
Ashkenazi Jews.

Case Presentation:

A 20-year-old female was admitted to the medicine department with complaints
of generalized weakness and easy fatigability, menorrhagia, and a dragging sensation in
the abdomen. On clinical evaluation, she had bone marrow failure syndrome features along with
massive splenomegaly. Later, she was confirmed with Gaucher disease type 1 disease by clinical
and investigation (low β-glucosidase level) evaluation.

Conclusion:

This case emphasizes keeping a differential diagnosis of glycogen storage disorder
while evaluating a case of unexplained pancytopenia with massive splenomegaly in adulthood
for an extended period. Currently, enzyme replacement therapy and substrate reduction therapy
are the mainstay therapeutic options for GD.
IoT based Predictive Modeling Techniques for Cancer Detection in Healthcare Systems
Authors: T. Ramya , M.P. Gopinath
Published: October 2023

Background:

The main objective of the Internet of Things (IoT) has significantly influenced and altered technology, such as interconnection, interoperability, and sensor devices. To
ensure seamless healthcare facilities, it's essential to use the benefits of ubiquitous IoT services to
assist patients by monitoring vital signs and automating functions. In healthcare, the current stateof-the-art equipment cannot detect many cancers early, and almost all humans have lost their lives
due to this lethal sickness. Hence, early diagnosis of cancer is a significant difficulty for medical
experts and researchers.

Methods:

The method for identifying cancer, together with machine learning and IOT, yield reliable results. In the Proposed model FCM system, the SVM methodology is reviewed to classify
either benign or malignant disease. In addition, we applied a recursive feature selection to identify
characteristics from the cancer dataset to boost the classifier system's capabilities.

Results:

This method is being applied in conjunction with fuzzy cluster-based augmentation, and
classification can employ continuous monitoring to forecast lung cancer to improve patient care.
In the process of effective image segmentation, the fuzzy-clustering methodology is implemented,
which is used for the goal of obtaining transition region data.

Conclusion:

The Otsu thresholding method is applied to help recover the transition region from a
lung cancer image. Furthermore, morphological thinning on the right edge and the segmentationimproving pictures are employed to increase segmentation performance. In future work, we intend
to design a prototype to ensure real-time analysis to provide enhanced results. Thus, this work
may open doors to carry patent-based outcomes.

Authors: Tewari Shilpa , Mukhopadhyay Chandra Shekhar
Published: October 2023

Background:

Comparative functional genomics will aid in the molecular identification
of diverse dog breeds.

Methods:

The current proposal aimed at conducting a differential study between the genomes of
exotic canines (Labrador, Basenji, Tasha-Boxer breed, Mischka breed German Shepherd, Zoey
breed Great Dane) and indigenous (Gaddi) breeds through whole genome annotation.

Results:

The prediction analysis by GeneMark tool yielded an average of 46484 transcripts, in
Gaddi dogs and exotic breeds ranging from 29669 to 30956. A total of 57 miRNAs were discovered in exotic breeds and 22 miRNAs in Gaddi dogs, 18 are common in both, while 4 were
unique to Gaddi dogs. lncRNA was predicted using the PLEK, CPAT, and LGC tools, resulting in
3201, 396, and 4188 noncoding sequences in exotic breeds, respectively. Approximately, 31
thousand lncRNA transcripts were identified in the Gaddi dog genome. Microsatellites were
found to be distributed through approximately 0.3% of both genomes. The average island length
of CpG ranged between 24246.48 to 28080.66 in exotic breeds at chromosome level assembly
and 697.15 in indigenous Gaddi dogs at contig level assembly. The predicted protein-coding
genes were subjected to pathway analysis by DAVID and PANTHER. Five genes that are expressed in the blood (INSL3, CLDN3, MYH1, CLN5, and GALC) were selected for validation
through qPCR. The results indicated that the genes were expressed in both groups.

Conclusion:

The study is the maiden report on the comparative genome analysis between indigenous Gaddi dogs and exotic dog breeds. The findings set the stage for further research into the
known and novel genes, which might be employed as biomarkers for disease diagnosis and to investigate their regulatory role.

Cassava is one of the most widely produced agricultural products in Indonesia with cassava peel waste of 20%. Cassava peel contains carbohydrates and stores a high cellulose content so that it has a potential to be a bioethanol. This study aims to utilize cassava peel waste for bioethanol production with an alkaline pretreatment process, cellulase enzyme hydrolysis and fermentation by using Zymomonas mobilis bacteria. Alkaline pretreatment with 14% NaOH is used to hydrolyze lignocellulose. The hydrolysis optimization process enzymatically applies the Surface Response Method (RSM) to determine the optimum conditions at hydrolysis pH in the range of 2-10 and hydrolysis temperature in the range of 30-70 °C by analyzing glucose levels using the Dinitrosalicylic Acid (DNS) method and UVvis spectrophotometry instruments. Surface Response Method (RSM) is likewise implemented to decide the greatest conditions of the fermentation process. The pH measurement ranges 2-10, and fermentation time takes 6 to 168 hours. Based on the results of research, it results a lignin content of 6.68% (b/b), cellulose content of 58.4% (b/b), and hemicellulose content of 27.3% (b/b). The optimum conditions of the hydrolysis process obtained an optimum glucose level of 9.22mg/mL at pH 2 and a hydrolysis temperature of 50°C. The optimum conditions of the fermentation process use Zymomonas mobilis at pH 6 while fermentation time takes 168 hours analyzed using a refractometer produced a bioethanol content of 37.75% (v/v) and a gas chromatography produced a bioethanol content of 54.94% (v/v).
Efectos físico-espaciales en el entorno urbano de la vivienda deshabitada Caso de estudio: centro histórico de Guadalajara, Jalisco
Authors: Breniz Hernandez Angelica Lucia
Published: October 2023

El propósito de este artículo es analizar los impactos físico-espaciales que ocasiona la vivienda deshabitada en el entorno urbano. Fuentes (2014) nos menciona que los signos visuales de abandono en las comunidades, tales como las altas tasas de desocupación de viviendas, pueden generar actitudes antisociales, y este tipo de desorden desincentiva la participación comunitaria y provee un espacio público y privado desregulado. Se considera desde una teoría urbanística que el exceso de viviendas deshabitadas da lugar a un funcionamiento ineficiente del espacio, perdiendo toda animación y actividad y entonces deja de ser un entorno urbano. De acuerdo con el Instituto Nacional de Estadística y Geografía (INEGI 2010), el estado de Jalisco en México es el segundo a nivel nacional, con 358.453 viviendas deshabitadas, en específico en el Área Metropolitana de Guadalajara, las cuales están localizadas tanto en las zonas periféricas como en el centro histórico, donde la tendencia actual son la intervención y densificación. La metodología propuesta para este trabajo consistió en la selección del caso de estudio con un alto porcentaje de vivienda deshabitada; por lo tanto, se seleccionó el Centro Histórico de Guadalajara, que presenta un 19,6%, área dentro de la cual se ubicaron cuatro puntos en los que se realizó el trabajo de campo mediante recorridos que permitieron elaborar una caracterización del entorno urbano por medio de perfiles de calle y entrevistas semiestructuradas, con el fin de contrastar la información de los efectos físico-espaciales que se manifiestan en espacios donde se concentra vivienda deshabitada. Como conclusión, en los cuatro puntos del centro histórico se observó un deterioro muy avanzado en su entorno urbano. Al respecto, el perfil de calle nos permitió observar un deterioro heterogéneo de la infraestructura vial, el mobiliario y los servicios urbanos; por su parte, los habitantes corroboraron este deterioro y su falta de inclusión en la toma de decisiones.
Alone within the ALONESS of Covid-19: Developing Contemplative, Artistic Inner Friendship for Turbulent Times
Authors: Franklin Michael
Published: October 2023

Art therapy, imaginal mindfulness, yoga, and meditation were personal and collegial necessities for surviving the emotional fallout of isolation during the Covid-19 pandemic. Combining these practices offered us credible resources for enhancing our social, cultural, and spiritual wellness when faced with the loneliness of lockdown living. This article applies an autoethnographic lens highlighting the value of these contemplative tools for managing pandemic related distress within myself and my professional peer group. The material gathered for this article is based on the authenticity of personal, smaller samples of shared, self-described observational phenomena. While these points were not formally studied with a review of scientific samples, the pandemic encouraged innovative forms of social communication between me, colleagues, and graduate students studying art therapy. Consequently, the information presented was consistently observed and shared between these professional communities. Self-reported findings from my confreres suggested outcomes of interiorized self-regulation skills such as focused attention, inner friendship/self-compassion, and witness awareness resulting from joining art with contemplative practices.

The aim of this research is to identify and examine the strategies of the fishing community in Tandurusa Village to survive in the face of weather changes. This research was conducted to obtain data that can be used as a reference in strategies and empowerment models to deal with weather changes which certainly greatly influence fishermen's catches which ultimately affects the household economy. This research was conducted in Tandurusa Village, Aertembaga District, Bitung City using a case study method. The population in this study were all fishermen in Tandurusa Village. The data collection technique was carried out using a sampling method, and the sample collection method used a purposive sampling method. The number of samples to be taken is 10% of the total population, namely 28 people. The data collected is in the form of primary data and secondary data. Primary data collection techniques using observation and interviews guided by questionnaires. The data obtained was analyzed using quantitative descriptive and qualitative descriptive analysis. Based on the results of the research carried out, the results obtained were that: Weather changes that occur every year can cause changes in the economy of fishermen's families. When the weather is friendly, it is often called harvest season because fishermen catch enough to fulfill all their household's living needs. On the other hand, when the weather changes, where strong winds and big waves, fishermen cannot go to sea to catch fish, so there is no income to support their living expenses. they. Situations like this make fishermen and their families look for ways or strategies to survive. There are 3 strategies used by fishermen in Tandurusa Village, Aertembaga District, Bitung City to survive. The three strategies are active strategy, passive strategy and network strategy, all three strategies are used and even combined according to the needs and situation and conditions of the fishing family faced at that time. The active strategy that fishing families use is to seek additional income outside of fishing at sea. Some fishing families are brave, trade, become motorbike taxi drivers, transport workers, construction workers and so on. The passive strategy used by fishing families is to save or reduce all living costs that can still be reduced as much as possible. Meanwhile, the last strategy used by fishing families to survive is the networking strategy, namely seeking loans from family, relatives, cooperatives, banks or others to maintain their family's lives.

The objective of this article is to analyze enunciative elements referring to the criteria for choosing the textbook from the Call for Proposals for the Registration and Evaluation Process of Didactic Works for the PNLD 2020 National Book and Teaching Material Program (BRASIL, 2018) , in a critical perspective regarding the effective inclusion of the Deaf and Deaf in the Brazilian educational political-pedagogical context, observing what has been produced as school material to support Portuguese Language classes. The hypothesis of this analysis is that the choice of the textbook will be permeated by the discourse of diversity, the inclusive look, the respect for identities through the bias of compliance with Law 10.436 / 2002 - Libras Law - in elementary school books II, 6th to the 9th year, as well as the recognition of the “Deaf Bodies” and their places as social subjects of law, proposing critical discursive reflections on the spaces historically denied in textbooks, at school, in the classroom, even reflecting on the BNCC / 2017 - diversified part. The methodology used is presented through bibliographic analysis dialoguing with national official documents, in order to broaden new horizons in the Brazilian educational construct, pointing out other ways for new selection criteria and choice of books, in addition to hegemonic impositions. Therefore, a dialogue is proposed between Foucault (2013; 2004), Azevedo; Piris (2016), Piris; Azevedo (2018), Pennycook (2003; 1998), Bakhtin (2003, 1998, 1999), Volochinov (2017); Orlandi (2003); Strobel (2009), Grigoletto (2011) and other bibliographies referring to the conceptions of voices, speeches, bodies and power, whose final perspective is to open reflections for new discussions.

Ensayos de historia Intelectual
Authors: Oliva Medina Mario
Published: October 2023

Los nueve ensayos de esta importante obra de historia intelectual nos remiten a cuatro relevantes temáticas de cara a la sociedad costarricense: Intelectuales, obras y quehaceres; Exilios; Intelectuales y movimientos sociales; Trincheras de ideas. La intelectualidad es mostrada en su real heterogeneidad urbana: social, política y cultural en el curso de la primera mitad del siglo XX. Mario Oliva sigue con acierto la propuesta teórico-metodológica de François Dosse al ubicar las ciudades desde las que los intelectuales encontraron sus respectivos lugares culturales de enunciación (literaria, ideológica y política), de la realización de sus quehaceres y desarrollo de sus redes. Queda claro en Ensayos de Historia intelectual que la circulación de ideas de los intelectuales estudiados tuvo desplazamientos discontinuos. Lo anterior explica sus diversas procedencias nacionalitarias y generacionales en las revistas culturales.

Authors: Dagade Om , Janjire Tejas , Jagdale Sai , Jawanjal Sanika
Published: October 2023

Abstract: As we know attendance is the crucial part in colleges, schools, corporate offices etc. Attendance plays an important role for keeping track of student’s record. Mostly attendance is taken manually in most of the colleges and schools. The manual attendance process involves taking attendance by calling the name or by signing the attendance sheet. This manual process is very time consuming and it is difficult to maintain the attendance record. Due to this drawback of manual attendance system, there is a need of automated attendance system. Here facial recognition plays an important part for automated attendance system. This suggested study focuses on face detection algorithm to provide automated attendance system. This proposed system uses Histogram of Oriented Gradients (HOG) and Deep Convolutional Neural Network for face detection and face recognition respectively to build automated attendance system.

This work aims to present an understanding of the main memory deficits in the early stages of Alzheimer's disease. For this, a bibliographical research was carried out in the Google Scholar database with keywords such as "early stage of Alzheimer's disease", "semantic memory" and "episodic memory". We explored the complexity of the disease, characterized by neurodegeneration and brain atrophy, with memory loss as a prominent symptom. We analyzed the phases of the disease, focusing on the initial phase subdivided into three stages. We detail each stage, highlighting its characteristics. We address biological changes, including the formation of senile plaques and neurofibrillary tangles, which disrupt synapses and affect communication between neurons. In the section on memory, we identify the affected types, mainly episodic and semantic memory, highlighting their importance in the early stages. We explore the relationship between biological changes and memory deficits. We conclude by emphasizing the complexity of the disease, the need for continuous research and the importance of early diagnosis. We discuss challenges in formulating universal treatments due to individual variation and societal changes. We highlight the urgency of future research to face the challenges of this devastating disease.
A Pair Measurement Surface Code on Pentagons
Authors: Gidney Craig
Published: October 2023

In this paper, I present a way to compile the surface code into two-body parity measurements ("pair measurements"), where the pair measurements run along the edges of a Cairo pentagonal tiling. The resulting circuit improves on prior work by Chao et al. by using fewer pair measurements per four-body stabilizer measurement (5 instead of 6) and fewer time steps per round of stabilizer measurement (6 instead of 10). Using Monte Carlo sampling, I show that these improvements increase the threshold of the surface code when compiling into pair measurements from ≈0.2% to ≈0.4%, and also that they improve the teraquop footprint at a 0.1% physical gate error rate from ≈6000 qubits to ≈3000 qubits. However, I also show that the teraquop footprint of Chao et al's construction improves more quickly than mine as physical error rate decreases, and is likely better below a physical gate error rate of ≈0.03% (due to bidirectional hook errors in my construction). I also compare to the planar honeycomb code, showing that although this work does noticeably reduce the gap between the surface code and the honeycomb code (when compiling into pair measurements), the honeycomb code is still more efficient (threshold ≈0.8%, teraquop footprint at 0.1% of ≈1000).

The article highlights the results of the work of the International Scientific and Practical Conference dedicated to the celebration of the 1100th anniversary of the adoption of Islam by the Volga Bulgaria "Russian Islam as a factor in strengthening inter-ethnic and inter-faith peace and harmony", held on November 24–25, 2022 in Kazan. The main thematic areas of the conference are revealed: Islam as a significant factor in the Eurasian space, its historical retrospective, the Soviet legacy, post-Soviet transformation, current challenges of our time, Russian Islamic education, faith-based institutions, identification processes among Muslims in Russia and the CIS countries, the risks of religious radicalisation and extremism, their social grounds, search for ways of anticipating and preventing conflicts. The participants came to the conclusion about the importance of preserving and updating the historical heritage of Russian Islam, taking into account the contribution of religious organizations to consolidation of spiritual and moral values and public service and to strengthening inter-faith harmony and civil solidarity in Russia and the CIS countries.
Book review: Makarova G.I. The image of Tatarstan in the strategies of the regional elites and in the public consciousness: a monograph (Kazan, 2020. 308 p.)
Authors:   National Research Ogarev Mordovia State University, Bogatova Olga A.
Published: October 2023

The review contains a brief overview of the content of the monograph by G.I. Makarova “The Image of Tatarstan in the Strategies of Regional Elites and in the Public Consciousness.” The book is based on the results of a sociological research in 2013–2019 in the Republic of Tatarstan. The author of the review draws attention to the complex and systemic nature of G.I. Makarova research work, confirmed by the synthesis of theoretical approaches to the problems of ethnic and regional identity, the image of territories, as well as the triangulation of methods. It is noted that the conclusions of the monograph are based on the results of several sociological methods – mass and expert surveys, in-depth interviews, analysis of official documents, and case studies. It is concluded that in the monograph G.I. Makarova developed a conceptual model for the analysis of the republican policy in the field of region branding and a methodology for sociological study of the results of its application. The conclusions and practical recommendations made by the author regarding the content of this policy and its social consequences, according to the reviewer, go beyond the boundaries of the Republic of Tatarstan. They can be used to study similar issues in other republics within the Russian Federation, while improving branding strategies and identity policies.

Published: October 2023

The article discusses the collection of objects of the Karakalpaks’ decorative and applied art in the funds of the I.V. Savitsky State Museum of Arts of the Republic of Karakalpakstan. The collection of folk-art objects is concentrated in the funds of the ethnography department of the museum. It comprehensively reflects the traditional everyday culture of the Karakalpak people. The objects of decorative and applied art of the Karakalpaks are concentrated in the following repositories: the fund of carpet products, jewelry, embroidery, wood, metal and leather products. Thematically, the collection is divided into jewelry items, horse equipment, carpets, yurt, clothing, kitchen utensils, and dishes. The author attempts to give a thematic and quantitative assessment of the collections of the Department of Ethnography. The analysis of the accession of exhibits did not allow identifying them by the area of existence, the place of purchase due to the absence of such information in the documentation. Most of the exhibits have only the information about the name of the object and its functional purpose. To create a complete picture of the accumulation of applied arts objects, statistical data on the accession of objects from 1967 to 2021 has been referred to, the dynamics of replenishment with exhibits is presented.
The religious situation in the Soviet village. Experience of microhistorical research
Authors:   Marjani Institute of History of the Tatarstan Academy of Sciences, Gallyamova Alfia G.
Published: October 2023

In the light of the Year of National Cultures and Traditions announced in the Republic of Tatarstan in 2023, the relevance of historical knowledge about individual ethno-regional loci is undeniable, which allows us to show the degree of preservation of the traditional origin in it on the real layer of culture. The purpose of the work is to analyze the role of the religious factor in the Soviet period in the life of one of the ancient Tatar villages – Novoe Nadyrovo Almetyevsk district. The objectives of the research are to reveal the factors and realities of the transformation of religious consciousness in the Soviet period since more than 70 in-depth interviews conducted in the village. From time immemorial, Islam has played a consolidating role in the life of the rural community, providing a system of strong ethical and moral foundations; despite the anti-religious policy of the Soviet state, the role of religion in the life of society has been preserved. The prism of microhistoric research conducted by the method of oral history seems to be very functionally effective for interpreting the retrospective of the twentieth century. It serves the non-opportunistic scientific connotations of history, which was subjected to powerful ideologization in Soviet historiography and, because of this, largely distorted the picture of the civilizational space.

One of the key conditions for the successful development of modern states is human capital. The international approach to calculating the Human Development Index, developed within the framework of the UN Development Program, is unified and does not pay attention to the socio-cultural (ethnic) factor. To assess its significance, the authors of the article carried out a discursive quantitative and qualitative analysis of the "Strategy for the socio-economic development of the Republic of Tatarstan until 2030" and semi-formalized interviews with experts. The purpose of the article: to identify the significance, foundations and meanings of the ethno-cultural component of the human capital of the Republic of Tatarstan and how they are implemented in practice. The results of the study revealed the high focus of Tatarstan on supporting the ethno-cultural component of the region’s human capital. Such a component is considered to be an indicator of the quality and diversity of the cultural life of the people living in Tatarstan. The republican government aims to develop human capital by supporting creative initiatives, motivating the population to build up creative competencies. The positioning of the republic as a region with international peace and harmony is used by Tatarstan to attract highly developed human capital from other regions and investors to stimulate its development.
