TESS Light Curves of Cataclysmic Variables. V. Improved or Corrected Orbital Periods of 53 Systems

The long and continuous high-time-resolution coverage of many stars by the Kepler and TESS space missions permit to explore periodic phenomena with a much higher precision than is possible with terrestrial observations. This includes the most basic property of binary stars, namely the orbital period. Here, I use TESS and Kepler light curves, sometimes in connection with other archival data and information taken from the literature, to improve or to correct the orbital periods of 53 cataclysmic variables with previously known periods. For 13 and 26 objects a significant or an incremental improvement, respectively, could be achieved. The periods of two systems that in the past had been only inferred indirectly were measured directly for the first time. In a remarkable 23% (12 stars) of all investigated systems previously reported orbital periods are shown to be wrong and require correction. Other interesting features seen in the light curves of some of the cataclysmic variables are briefly mentioned, but a more detailed investigation is postponed to future work.

Digital Transformation of Archives in the Context of the Introduction of an Electronic Document Management System in Kazakhstan

Abstract The relevance of this study is conditioned by the significant importance of the organisation of electronic document management in the Republic of Kazakhstan and the broad prospects that open up during the digitalisation of state archives. The purpose of the study is to investigate the key aspects of the digitalisation of archives in Kazakhstan at the current stage of the country’s economic development. The basis of its methodological approach was a theoretical investigation of the processes of digitalisation of archival information under the conditions of practical application of the electronic document management system in the Republic of Kazakhstan, with the results obtained indicating the major significance of the digital transformation of archives in the context of the programmes Resolution of the Government of the Republic of Kazakhstan No. 827 “About Approval of the State Program “Digital Kazakhstan” (2017) and “Information Kazakhstan-2020”: State Program (2021) adopted at the state level. The sequential transfer of archival information to digital media for storage offers numerous advantages over traditional paper media, with the state level in Kazakhstan regulating the digital transformation of archives and the adoption and use of a unified electronic document management system by enacting a number of laws that regulate a wide range of related issues. The introduction of an electronic document management system has also established numerous advantages, largely determining the significant prospects for the development of this system of interaction between organisations (state, public, legal entities, and individuals). The practical significance of the results obtained lies in the possibility of their application in the organisation of the activities of enterprises and organisations of the Republic of Kazakhstan that implement measures to digitalise archival data within the unified electronic document management system.

Revisiting Elevated δ13C Values of Sediment on Modern Carbonate Platforms

AbstractThe measured carbon isotopic compositions of carbonate sediments (δ13Ccarb) on modern platforms are commonly 13C‐enriched compared to predicted values for minerals forming in isotopic equilibrium with the dissolved inorganic carbon (DIC) of modern seawater. This offset undermines the assumption that δ13Ccarb values of analogous facies in the rock record are an accurate archive of information about Earth's global carbon cycle. We present a new data set of the diurnal variation in carbonate chemistry and seawater δ13CDIC values on a modern carbonate platform. These data demonstrate that δ13Ccarb values on modern platforms are broadly representative of seawater, but only after accounting for the recent decrease in the δ13C value of atmospheric CO2 and shallow seawater DIC due to anthropogenic carbon release, a phenomenon commonly referred to as the 13C Suess effect. These findings highlight an important, yet overlooked, aspect of some modern carbonate systems, which must inform their use as ancient analogs.

Secure computation protocol of Chebyshev distance under the malicious model

Secure multi-party computation of Chebyshev distance represents a crucial method for confidential distance measurement, holding significant theoretical and practical implications. Especially within electronic archival management systems, secure computation of Chebyshev distance is employed for similarity measurement, classification, and clustering of sensitive archival information, thereby enhancing the security of sensitive archival queries and sharing. This paper proposes a secure protocol for computing Chebyshev distance under a semi-honest model, leveraging the additive homomorphic properties of the NTRU cryptosystem and a vector encoding method. This protocol transforms the confidential computation of Chebyshev distance into the inner product of confidential computation vectors, as demonstrated through the model paradigm validating its security under the semi-honest model. Addressing potential malicious participant scenarios, a secure protocol for computing Chebyshev distance under a malicious model is introduced, utilizing cryptographic tools such as digital commitments and mutual decryption methods. The security of this protocol under the malicious model is affirmed using the real/ideal model paradigm. Theoretical analysis and experimental simulations demonstrate the efficiency and practical applicability of the proposed schemes.

Reflective Paper

This article aims to investigate the changes that have been generated in archival systems through digitisation and the relevance of reactivating archives through artistic creation and specifically through printmaking. In this paper, I will present some projects from my practice to analyse the meaning of these new physical forms created from diverse archives. Digital technology has transformed the way we communicate and store information. Today’s images are virtual and fleeting; they slip from our memory, prompting the question of how much time we spend examining/absorbing an image. Why store thousands of images if we never revisit them? Archival information today is digitally stored and recorded, but can we access it and which archives do we choose to recreate? By revisiting material from the past, we might better understand our present. The relationship between archival materials and their stories as generators of new readings through artistic practice occupies a significant place in contemporary art research. In this study, I explore different photographic archives from my artistic practice, using graphic techniques that allow me to reflect on memory and its evanescence. My interest in working with these memories is related to the desire to share materials from the past and generate new relationships within our contemporary context. Working with various temporalities is an approach to understanding the functioning of both individual and collective memory

Transmutation of The Reproductive Life of Women in Southern/West Cameroon(S) 1922-1972: A Colonial Manipulation

In all human communities, societal continuity depended on the quality and availability of infant and maternity welfare services. Conscious of the outcomes of infancy care on the productive efficiency of individuals at adulthood, the reproductive life of women and child welfare became an area of European domination during colonialism. Using British Southern/West Cameroon(s) as the theatre, this paper sets out to uncover colonial motives in the transformation of reproductive practices among women as it examines the different strategies and mechanisms employed in extending maternity and infant welfare as a measure of colonial imperialism. Archival information and oral interviews made up primary sources while books, published articles and dissertations constituted the secondary sources. The descriptive historical approach was employed in the analysis of the work. This paper submits that: the British colonial administration in Southern Cameroons had a mask colonial exploitative economic agenda behind the assignment put forth by the League of Nations Mandate Commission in its Article II of the British Mandate agreement. A baseless racial discrimination and cultural domination motivated the transformation of the reproductive life of indigenous women and the extension of basic infant welfare services during the Mandate and trusteeship periods in Southern Cameroons. These services were mostly provided by Western Mission agencies and plantation firms who recognized the independence of Southern Cameroons but withheld the rights to medical autonomy. In some cases, the transfer of rights to manage the medical arm of the different agencies was partially transferred during the last years of the Cameroon federation and in some cases after the abrogation of the Cameroon federation. The British decision to administer Southern Cameroons as a mandate was a conspiracy to enforce the tentacles of colonialism and its diverse arms with hope of greater economic and cultural gains.

Primary to post-depositional microbial controls on the stable and clumped isotope record of shoreline sediments at Fayetteville Green Lake.

Lacustrine carbonates are a powerful archive of paleoenvironmental information but are susceptible to post-depositional alteration. Microbial metabolisms can drive such alteration by changing carbonate saturation insitu, thereby driving dissolution or precipitation. The net impact these microbial processes have on the primary δ18O, δ13C, and Δ47 values of lacustrine carbonate is not fully known. We studied the evolution of microbial community structure and the porewater and sediment geochemistry in the upper ~30 cm of sediment from two shoreline sites at Green Lake, Fayetteville, NY over 2 years of seasonal sampling. We linked seasonal and depth-based changes of porewater carbonate chemistry to microbial community composition, insitu carbon cycling (using δ13C values of carbonate, dissolved inorganic carbon (DIC), and organic matter), and dominant allochems and facies. We interpret that microbial processes are a dominant control on carbon cycling within the sediment, affecting porewater DIC, aqueous carbon chemistry, and carbonate carbon and clumped isotope geochemistry. Across all seasons and sites, microbial organic matter remineralization lowers the δ13C of the porewater DIC. Elevated carbonate saturation states in the sediment porewaters (Ω > 3) were attributed to microbes from groups capable of sulfate reduction, which were abundant in the sediment below 5 cm depth. The nearshore carbonate sediments at Green Lake are mainly composed of microbialite intraclasts/oncoids, charophytes, larger calcite crystals, and authigenic micrite-each with a different origin. Authigenic micrite is interpreted to have precipitated insitu from the supersaturated porewaters from microbial metabolism. The stable carbon isotope values (δ13Ccarb) and clumped isotope values (Δ47) of bulk carbonate sediments from the same depth horizons and site varied depending on both the sampling season and the specific location within a site, indicating localized (μm to mm) controls on carbon and clumped isotope values. Our results suggest that biological processes are a dominant control on carbon chemistry within the sedimentary subsurface of the shorelines of Green Lake, from actively forming microbialites to pore space organic matter remineralization and micrite authigenesis. A combination of biological activity, hydrologic balance, and allochem composition of the sediments set the stable carbon, oxygen, and clumped isotope signals preserved by the Green Lake carbonate sediments.

From the Concept of Storing Documents in Electronic Form to the Regulatory and Legal Basis of Creating National Archival and Library Information Resources

The aim of the article is to study conceptual principles of storing documents in electronic form, in particular, electronic documents, digital documents and creating metadata for them, taking into account integration processes of grounding national information resources in archival and library spheres of activity. Additionally, to trace tendencies in the implementation of existing concepts, to identify the best Ukrainian practices, to highlight defects, and offer possible ways to solve problems. Research methods. This study uses the following methods: theoretical, as moving from the abstract to the concrete, reality reflection in thinking; empirical, as observation and comparison; complex, as system analysis, synthesis and modulation; special, as graphic and component analysis; prognostication. Scientific novelty consists in implementating a systematic interdisciplinary comparative analysis of the problem of storing documents in electronic form in archives and libraries, in order to determine the directions for solving this problem, using the definition of common requirements for similar information objects and processes, particularly, in the context of the initiative to create the National Electronic Library of Ukraine, in which it is offered to integrate information on objects of national heritage stored in archives, libraries, museums, as well as thereafter data from publishers. Main conclusions. Based on the results of this research, it should be stated that Ukrainian archivists achieved the greatest success in developing the overall system from creation the documents in electronic form to their transmission for permanent storage. An important issue is the development of the “long-term storage” system, the formation of which, in our opinion, should begin with the requirements for the information objects with which this system will be filled. This will significantly affect the structure and content of the metadata needed to manage this system. The successful experience of Ukrainian archivists and librarians should be used here. The most urgent task is to put the finishing touches to the Concept of creating the National Electronic Library of Ukraine according to the best domestic and foreign practices.

Prevalence Of Flabby Ridge In Completely Edentulous Patients Among The Chennai Population

Aim: The aim of this present study was to evaluate the prevalence of flabby ridge in completely edentulous patients among the Chennai population. Background: Flabby tissue refers to excessive and movable soft tissue, while a ridge is an elevated, long, narrow, and raised crest. A flabby ridge is a specific condition characterized by the mobility of the soft tissue of maxillary or mandibular alveolar ridge. This occurs when soft tissue hyperplasia replaces the underlying alveolar bone. Materials and Methods: The study is a retrospective study with data collection obtained from Dental Information Archiving Software (DIAS). Parameters assessed include age, gender, and flabby ridge patients. The collected data was tabulated in Microsoft Excel sheet and statistically analyzed. The correlation between the prevalence of flabby ridge, genders and different ages was analyzed by employing the Chi-Square test. Results: In the present study, a total of 31 patients aged between 31 to 85 year old were assessed for specific parameters such as gender, ages, flabby ridge, and its occurrence in different arches. Patients with flabby ridge were found more in females with 83.9% when compared to males. The most common age group is 51 to 60 years old with a 41.9% prevalence. The maxillary arch is most commonly affected by flabby ridge (55.6%) compared to the mandibular arch. There is a positive correlation between gender and flabby ridge prevalence with a p-value <0.05 (statistically significant). However, the correlation between age and flabby ridge prevalence showed insignificant value, p>0.05. Conclusion: Within the limits of the present study, the prevalence of flabby ridge among the completely edentulous patient, female is most affected with the most common age between 51 to 60 years old and the maxillary arch being the most common arch.

Assessment of Turnaround Time (TAT) for Oral Squamous Cell Carcinoma Biopsies: A Single-Institution Experience.

Oral squamous cell carcinoma (OSCC) is one of the most common cancers worldwide. A delay in the diagnosis of OSCC can have a drastic impact on management and patient outcomes. One of the most crucial elements in oral management is the timely histopathological final diagnosis. Turnaround time (TAT) is regarded as the most important component of the quality performance evaluation. Many labs have struggled to improve their TATs despite advancements in computerization, transport systems, and analytical technologies. Aim: This study aimed to assess the TAT of OSCC cases, assess the mean TAT period, evaluate any TAT delays, and explore the reasons behind the TAT delays. Materials and methods: OSCC reports in Saveetha Dental College and Hospitals, Chennai, for one year from January 1, 2022, to December 31, 2022, were retrieved from the Dental Information Archival Software (DIAS), and the mean TAT was noted. Further, the number of cases with delay in TAT was also observed, and the reason for their delay was listed. Descriptive statisticsand graphical representation were performed utilizing IBM SPSS Statistics for Windows, V. 23.0 (IBM Corp., Armonk, NY, USA). One-way ANOVA was performed with a significance set at a p-value less than 0.05. 230 OSCC cases were retrieved and included in the TAT evaluation for this study. Among 230 cases, 161 (70%) were incisional and 69 (30%) were excisional biopsies. Only seven (4%) incisional cases and seven (10%) excisional biopsies showed a delay in TAT. The most common reason for the delay in TAT was the requirement for deeper sections and decalcification of bone specimens. Out of 161 incisional cases, only 48 (29%) have undergone excision and further treatment. Twenty-one out of 69 (30%) excisional cases were found to be referral cases from other private institutions. The overall average TAT for 12 months was 3.24 ± 0.41 days for incisional biopsies and 11.88 ± 2.07 days for excisional biopsies. One-way ANOVA revealed a statistically significant p-value of less than 0.00001. Our study sheds light on specific challenges in TAT delay and opportunities for the improvement of TAT. This can result in faster TAT of OSCC reports, further improve patient care, and enable prompt treatment. This study quantified the TAT for OSCC cases and identified critical areas for process improvement. The findings can inform strategies to streamline diagnostic workflows, reduce delays, and ultimately improve the timely delivery of care to patients with OSCC.

Epidemiological Trends and Clinicopathological Characteristics of Oral Leukoplakia: A Retrospective Analysis From a Single Institution in Chennai, Tamil Nadu, India.

Background India has a high prevalence of oral potentially malignant disorders and malignant transformation. Cases of oral leukoplakia are not commonly encountered, and only a small cohort of patients undergo biopsies for the same. This study aims to assess the various etiological factors causing leukoplakia, the clinical features, histopathological findings, and treatment received by the patients who were histopathologically diagnosed with oral leukoplakia. Methodology Oral leukoplakia cases were included in this study from total biopsy samples received in the oral pathology department. Details were collected from the Dental Information Archival Software of our institution. The period analyzed was from January 1, 2021, to December31, 2023. Relevant clinical and histopathological details were retrieved and tabulated. Statistical analysis (chi-square test) was used to assess the association between the clinicopathological parameters using SPSS software version 21.0 (IBM Corp., Armonk, NY, USA) with a significance level set at a p-value <0.05. Results A total of 76 oral leukoplakia cases were retrieved from 2,600 biopsy samples. The prevalence of oral leukoplakia was 3.1% to 3.4% for the three years. Leukoplakia was commonly observed in those aged 51 to 60 years (33%). Overall, 21% of the patients with leukoplakia showed severe epithelial dysplasia, 22% showed mild epithelial dysplasia, and 39% showed moderate epithelial dysplasia. Moreover, 30% of the patients presented with leukoplakia and oral submucous fibrosis and showed varying degrees of epithelial dysplasia. Finally, 45% of the patients were managed conservatively using pharmacotherapy. Conclusions Severe epithelial dysplasia was commonly associated with oral leukoplakia. Oral submucous fibrosis was also found to be associated with leukoplakia and showed epithelial dysplasia. None of our proliferative verrucous leukoplakia cases showed any association with oral submucous fibrosis. Surgical management was the preferred treatment.

Interactive 360° media for the dissemination of endangered world heritage sites: the ancient city of Palmyra in Syria

Since the onset of conflict in Syria in 2011, several heritage sites have suffered partial or complete destruction. The ancient city of Palmyra, a UNESCO World Heritage Site since 1980, was placed on the List of World Heritage in Danger in 2013, alongside five other Syrian heritage sites. Between 2015 and 2017, Palmyra experienced the loss of nearly 40% of its historic buildings and landmarks. The site’s remote location and ongoing armed conflict pose additional challenges in accessing and preserving it.This paper introduces an interactive online platform employing 360° media to document and disseminate information about the world heritage site of Palmyra. The platform contributes to the safeguarding process of Palmyra, facilitating public engagement and interaction with the site. It also has potential applications for other sites in Syria and beyond. The platform allows users to explore both archival and current information of damaged historical monuments and buildings, revealing their layered histories before and after demolition. Employing interactive 360° media, similar to applications like Google Street View, the platform offers a reality-based digital environment. Users can virtually move into different buildings or follow specific pathways within the site, accessing archival information and documentation about particular monuments and buildings along their journey.This project serves as a unique informational resource for decision-makers and policy planners, aiding in the understanding of the site and the development of relevant strategies and recommendations. It also proves beneficial as an educational tool. The collective understanding fostered by this platform is expected to positively influence post-conflict restoration and reconstruction plans, making it an invaluable asset for research and educational purposes.
