Early polar-orbiting satellite-based fire remote sensing during the 1960s

ABSTRACT Satellite-based sensors such as the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Visible Infrared Imaging Radiometer Suite (VIIRS) now routinely provide a detailed picture of global fire activity on a daily basis. These systems explicitly included biomass burning as a phenomenon of interest, and their design was heavily influenced by experience gained with the comparatively primitive Advanced Very High Resolution Radiometer (AVHRR) first deployed on the TIROS-N satellite in the late 1970s. The AVHRR is generally recognized as the earliest spaceborne sensor to provide a middle infrared (MWIR) channel sensitive to actively burning vegetation fires and other high-temperature, sub-pixel thermal anomalies, forming the basis of countless fire studies before higher quality MODIS data became available. Here, we consider in the context of active fire monitoring a sensor much older than the AVHRR, namely the High Resolution Infrared Radiometer (HRIR) on board NASA’s Nimbus-I, -II, and -III satellites, launched in 1964, 1966, and 1969, respectively. This early imaging sensor had a single MWIR channel primarily intended for night-time meteorological observations (a complementary daytime near-infrared channel was added for Nimbus-III) that could potentially serve as a source of pre-AVHRR active fire data. To this end, we inspected night-time HRIR imagery acquired over the western United States and found unambiguous evidence of multiple confirmed wildfires in 1966. In addition, we found strong evidence of actively burning fires in Africa, specifically the Democratic Republic of the Congo, western Zambia, and northern Namibia, and in northern Australia, commensurate with their fire seasons. Our findings indicate that it was actually the HRIR that acquired the earliest MWIR imagery that could be used for identifying biomass burning from space, well over a decade before the first AVHRR was deployed. We found in addition that the retrieval of fire radiative power (FRP) from higher dynamic-range HRIR observations was potentially possible pending refined calibration.

Variation of temperature increase rate in the Northern Hemisphere according to latitude, longitude and altitude: the Turkey example

Global climate change notably influences meteorological variables such as temperature, affecting regions and countries worldwide. In this study, monthly average temperature data spanning 73 years (1950–2022) were analyzed for 28 stations in the city centers across seven regions of Turkey. The station warming rates (SWR) were calculated for selected stations and the overall country using Singular Spectrum Analysis (SSA) and Least Square Polynomial Fit (LSPF) methods. The temperature trend in Turkey exhibited a decline until the late 1970s, followed by a continuous rise due to global warming. Between 1980 and 2022, the average SWR in Turkey was found to be 0.52 °C/decade. The SWR was determined to be the lowest in Antakya (0.28 °C/decade) and the highest in Erzincan (0.69 °C/decade). The relationship between SWR and latitude, longitude, altitude, and distance to Null Island (D2NI) was explored through linear regression analysis. Altitude and D2NI were found to be the most significant variables, influencing the SWR. For altitude, the correlation coefficient (R) was 0.39 with a statistically significant value (p) of 0.039. For D2NI, R, and p values were 0.39 and 0.038, respectively. Furthermore, in the multiple regression analysis involving altitude and D2NI, R and p values were determined to be 0.50 and 0.029, respectively. Furthermore, the collinearity analysis indicates no collinearity between altitude and D2NI, suggesting that their effects are separated in the multiple regression.

“I Have Never Visited a Health Center”: Ethiopian Centenarians’ Perceptions of Their Health Conditions

The global centenarian population is expected to reach 4 million by 2050, yet little is known about the health status of centenarians in Sub-Saharan Africa. A case study examined the health conditions and functionality of nine Ethiopian centenarians. In-depth interviews revealed that all nine were Orthodox Christians and lived with extended family; eight were male. Aside from minor health complaints, centenarians in rural Ethiopia perceived that their sensory/cognitive functionality was normal until their late 90s. Despite a lack of medical care, the centenarians included two survivors, four delayers, and three escapers. Centenarians in rural Ethiopia were embedded in closely knit, religious, multigenerational households and communities and aspired to live resiliently. These findings call for the consideration of the unique health status of centenarians in Global South nations in their own cultural context.

Rett syndrome: A coming of age

Rett syndrome (RTT) was first recognized in the late 1950s by Andreas Rett in Vienna and Bengt Hagberg in Uppsala. Hagberg, following a meeting with Rett, decided to call the disorder Rett syndrome in the landmark paper which appeared in the Annals of Neurology in 1983. That report led to the worldwide recognition of this relatively young and unique neurodevelopmental disorder, the concerted effort to establish its epidemiology, etiology, and natural history, and the establishment of clinical criteria for its diagnosis. Our understanding of RTT progressed rapidly, in part due to the remarkable diagnostic advances in genetics linking RTT with variations in the methyl-CpG-binding protein 2 (MECP2) gene at Xq28. In 2003, the NIH funded a Natural History study of RTT and related disorders which provided critical cross-sectional and longitudinal data that resulted in the increased understanding of RTT, the development of better management strategies, and an increase in pharmaceutical and gene-based products designed to provide specific therapies. The FDA-approved oral agent trofinetide has been shown to provide incremental improvements in the core features of RTT. Two gene-based therapies are currently being assessed in clinical trials in Canada and the US. Additional treatment strategies are being assessed at the clinical and translational levels.

The Gypsy condition in Kiskunhalas: work, consumption, and indebtedness after socialism

ABSTRACT The article outlines the recent history of the Gypsy minority in the town of Kiskunhalas, Bács-Kiskun county, with an emphasis on its changing economic situation. Gypsy households benefited from secure employment until the late 1980s. Some of them were able to profit from the embourgeoisement opportunities available to all citizens in the socialist mixed economy. Under postsocialist conditions, however, most Gypsies face uncertainty and hardship in everyday life. Theoretically, the article engages with the work of Michael Stewart, who has argued that the demise of socialism and the replacement of central planning and compulsory wage-labour by the freedoms of market society brought opportunities for Gypsies to prosper economically, as well as to reassert a cultural identity which had been stymied for decades. I argue that this libertarian perspective overlooks the very real disadvantages that most members of the minority experienced after 1990, and which they have continued to experience in different forms under Fidesz-led governments since 2010. Like the poorest segments of the ethnic Hungarian population, Gypsies are exposed to neoliberal capitalism in its distinctive postsocialist populist form. The article concludes with an exploration of everyday financialization: indebtedness entrenches class differences and has negative consequences for persons, households and communities.

Did China conjure up its narrative on the territorial claim on the Indian border?

The purpose of the article is to (not test, but) explore the hypothesis that the People’s Republic of China (1949 to date), hereinafter China, conjured up its narrative on the territorial claim on the Indian border. The body of evidence put together for the purpose has been obtained mainly from the exchanges between India and China on the boundary question between the late 1950s and mid-1960s and the material in respect of the Tibet (Simla) Conference (1913–14). The exploration reaffirms preponderance of evidence that exists to conclude that China conjured up its narrative on the territorial claim on the Indian border.

The Italian Constitutional Court and recentralization along the pendulum of regionalism

AbstractThis paper employs a quantitative analysis of the disputes between central and regional government concerning the role of the Italian Constitutional Court, focusing on the context of decentralization initiated during the late 1990s. The econometric evidence demonstrates a significant decrease in favourable outcomes for regional governments following the process of recentralization, which was commenced by central government in 2011 in response to a major financial crisis. The results of this study support the perspective of a centralistic attitude of the courts in litigation concerning subnational governments and provide fresh insights into the role of the courts in the relationship between recentralization and major economic crises.

Prevalence and intensity of soil-transmitted helminth infections among school-aged children in five districts in Uganda.

Soil-transmitted helminth (STH) infections, commonly caused by roundworms (Ascaris lumbricoides), whipworms (Trichuris trichiura), and hookworms (Necator americanus and Ancylostoma duodenale), were widespread among Ugandan schoolchildren in the late 1990s and early 2000s. Since 2003, the Ugandan Ministry of Health has administered biannual preventive chemotherapy to children aged 1-14 years to control these infections. Twenty years after the program's inception, there is scant data to show the long-term impact of these national deworming efforts. To estimate the prevalence and intensity of STH infections among 10-14-year-old primary school children, school-based, cross-sectional surveys were conducted in November 2023 across five districts (Kamwenge, Sheema, Adjumani, Lamwo, and Zombo). Sixty-five children from five schools per district were selected for inclusion. Fecal egg counts were determined using the Kato-Katz microscopy technique, performed in duplicate by trained laboratory technicians. The survey findings revealed a high prevalence of any STH infection in Kamwenge District (21.2%, 95% confidence limits (CL): 5.7%, 36.6%), while the remaining four districts exhibited lower prevalences, ranging from 0.4% (95% CL: 0.0%, 1.2%) in Adjumani District to 5.6% (95% CL: 0.0%, 11.4%) in Sheema District. The prevalence of moderate-to-heavy-intensity infections was below 1% across all districts. A. lumbricoides was identified infrequently. Hookworm infections were primarily identified in the western districts of Kamwenge and Sheema, while T. trichiura infections were common only in Kamwenge District. Hookworm and T. trichiura infections were uncommon in the northern districts of Adjumani, Lamwo, and Zombo. These surveys suggest that morbidity due to STH infections among schoolchildren may be well controlled in these five districts, as evidenced by low moderate-to-heavy-intensity infection prevalence. However, the prevalence of any intensity infection remains elevated in some districts, indicating the need for continued preventive chemotherapy distribution. A reduction from biannual treatment may be warranted in four districts, per World Health Organization recommendations.

Interdecadal change in the relationship between the South China late rainy season rainfall and equatorial Pacific SSTs

Abstract The South China (SC) late rainy season rainfall (SCLR) is important to people’s livelihoods and properties of this densely populated and economically developed region. Based on observation and reanalysis datasets, this study identifies that the relationship between the SCLR and equatorial Pacific SSTs (EPSSTs) experiences an interdecadal change around the late 1970s. The SCLR is negatively correlated with the eastern EPSSTs during 1948–1977 (the previous epoch) but positively correlated with the central EPSSTs during 1978–2022, especially during the last three decades 1993–2022 (the post epoch). This is due to the interdecadal change in El Niño flavors and EPSSTs-tropical Atlantic SSTs (TASSTs) relationship. With the increasing frequency of central Pacific El Niños in the post epoch, the El Niño-related warm SST anomaly center shifts from the eastern equatorial Pacific (EEP) to the central equatorial Pacific (CEP). Correspondingly, the anomalous cyclone exerted by the CEP warming reaches SC and causes rainfall surplus there (westward propagation pathway). In contrast, the EEP warming in the previous epoch can’t influence the SCLR through the westward propagation pathway, but through shifting the westerly jet southward via heating the tropical troposphere. The southward shifted westerly jet crashes the Qinghai-Tibet Plateau, triggering cyclonic circulations across the northern East Asia and North Pacific, which in turn cause anticyclonic circulations over the western SC and reduce SC rainfall (eastward propagation pathway). On the other hand, the CEP warming in the post epoch barely influence the SCLR through the eastward propagation pathway because of the enhanced negative relationship between EPSSTs and TASSTs.

An introduction to integrated circuit for non-expert

Integrated circuit (IC) has transformed the field of electronics and technology. In this work, we provide a straightforward introduction to IC for non-experts, covering the beginning and growth of IC from its initial conception in the late 1950s through its ongoing evolution in the modern era. We explore the significant impact of IC on various aspects of daily life, including healthcare, transportation, entertainment, etc. We will talk about how to understand IC, types of IC, its development, and applications. Learning about IC is so important for everyone in this era because it almost has a strong connection with our daily lives, so our modern world can not go on without IC. You could not imagine how the world would work if we did not have IC technology. So, this article aims to let non-experts know about the essential role of IC in our interconnected world and illustrate how the IC has shaped our daily lives and inspired technological advancements.

Criminalizing Abuse, Neglect, and Financial Exploitation of Older Adults

The criminalization of abuse, neglect, and financial exploitation of older adults did not begin until the late 1990s in the United States. During this time, a number of states enacted laws criminalizing certain abusive and exploitive behaviors committed against older adults and added punishment enhancements to existing laws if victims were over a certain age. These laws and policies, and the impetus for them, mirrored those enacted decades prior as part of the child welfare movement, with connections drawn between the vulnerability of younger and older victims. Despite passage of these various abuse and exploitation laws for older adults, significant challenges remain in the identification, investigation, and prosecution of crimes committed against this population. Further, the population of older adults has been rapidly expanding along with rates of victimization, elevating the importance of this escalating social problem. This paper identifies limitations in the prior research by describing the past, present, and likely future of U.S. law and policy intended to effectively respond to crimes against older adults and concludes with a research and policy agenda.

Evaluation of The Effectiveness of HIV Prevention Strategies on HIV Prevalence Among Men and Women in Zoba-Ma’akel/Eritrea

Human Immunodeficiency Virus (HIV) emerged in the late 1970s and is transmitted through unprotected sex, mother-to-child transmission, drug use and contaminated medical tools. HIV have continued yet, as health and development problems through the world. This study assesses the effectiveness of HIV prevention strategies in Zoba-Ma’akel/ Eritrea, focusing on gender disparities in HIV prevalence. Using Convergent-Parallel-Mixed-Method of Research Design, the study gathered quantitative data from 150 people living with HIV, and qualitative data from experts and community leaders. The quantitative data were processed using SPSS, while qualitative data were analyzed in thematic and content-based methods. The study found a significant decline in HIV prevalence in Zoba-Ma’akel over the past decade, but noted persistent new infections and higher prevalence among women. Key findings highlighted the importance of HIV education, the impact of gender-based violence, stigma, unemployment and the effectiveness of Antiretroviral Therapy. Innovative strategies, such as establishment of Association for People Living with HIV, couple testing, and integrated HIV-TB prevention, were identified as crucial. The study recommended targeted interventions for high-risk groups and emphasized the need for women's empowerment programs. Despite challenges, the study provided valuable insights for policymakers and future research

Chromosome 7 gain compensates for chromosome 10 loss in glioma.

The co-occurrence of chromosome 10 loss and chromosome 7 gain in gliomas is the most frequent loss-gain co-aneuploidy pair in human cancers. This phenomenon has been investigated since the late 1980s without resolution. Expanding beyond previous gene-centric studies, we investigated the co-occurrence in a genome-wide manner taking an evolutionary perspective. Mining of large-scale tumor aneuploidy data confirmed the previous finding of a small-scale longitudinal study that the most likely order is chromosome 10 loss followed by chromosome 7 gain. Extensive analysis of genomic and transcriptomic data from both patients and cell lines revealed that this co-occurrence can be explained by functional rescue interactions that are highly enriched on chromosome 7, which could potentially compensate for any detrimental consequences arising from the loss of chromosome 10. Transcriptomic data from various normal, non-cancerous human brain tissues were analyzed to assess which tissues may be most predisposed to tolerate compensation of chromosome 10 loss by chromosome 7 gain. The analysis indicated that the pre-existing transcriptomic states in the cortex and frontal cortex, where gliomas arise, are more favorable than other brain regions for compensation by rescuer genes that are active on chromosome 7. Collectively, these findings suggest that the phenomenon of chromosome 10 loss and chromosome 7 gain in gliomas is orchestrated by a complex interaction of many genes residing within these two chromosomes and provide a plausible reason why this co-occurrence happens preferentially in cancers originating in certain regions of the brain.

Референдум о независимости Черногории 2006 года: этноязыковые аспекты

The purpose of the study is to determine the influence of the factor of ethnolanguage identification of the population of Montenegro on the results of the 2006 independence referendum. The article presents arguments pointing to a stable territorial split of Montenegro, confirmed by census materials, the results of referendums in 1992 and 2006, as well as the course of parliamentary and presidential elections. Montenegrins, Serbs and representatives of other ethnic communities have completely different assessments of the geopolitical situation of the republic and have their own vision of the further development of Montenegrin statehood. The scientific novelty of the study consists in an attempt to show a clear correlation of the voting results in each community with the ethnocultural identity of the local population, due to the historical conditions of residence of a particular region within the Montenegrin state. As a result of the study, it was determined that the Orthodox majority of the republic is in a state of deep division into two approximately equal groups – Serbs and Montenegrins. Their separation on the issue of maintaining a unified state entity with Serbia was noticeable even during the collapse of greater Yugoslavia, and finally took shape in the late 1990s and early 2000s in connection with the new course of the political leadership of Montenegro to achieve full independence from Serbia.

"Expand the range, improve the quality of service...": about the organization of trade and public catering on the Moscow-Kursk-Donbass railway in the late 1950s

The relevance of the stated topic is determined by the special social significance of trade and public catering in the daily life of the population. Moreover, in modern conditions, their role is not decreasing, but only increasing. Improving the mechanisms of functioning of the service sector can be successful not only with the active use of the achievements of digital civilization, but also with the rational use of the experience of previous generations. In scientific and historical terms, the topic of organized satisfaction of consumer demand for food and basic necessities is little studied, especially in relation to the recent Soviet past. The issues of the history of departmental trade and catering have also not received adequate coverage in the scientific literature, which motivates their development from the standpoint of the methodological apparatus available to scientists today.The purpose of the study is to summarize the experience of organizing trade and catering in railway transport in the late 1950s on the basis of archival documents and published materials.The objectives: to reveal the specifics of transport trade in the period under review; characterize the problems of organizing catering for railway workers.Methodology. The research was based on the principles of objectivity and historicism. To solve the problems, the author used historical-genetic, historical-systemic, historical-comparative, typological, and retrospective methods.Results. The study of the experience of trade and catering enterprises of railway transport made it possible to objectively assess the role of departmental social policy in creating favorable conditions for the performance of professional duties by employees with a special working regime.Conclusions. The main problem in the organization of transport trade and nutrition during the study period should be recognized as the inability to organize an uninterrupted supply of food to workers who worked on remote crossings and linear sections. The other traditional flaws of Soviet trade and catering were also characteristic of the railway sphere of labor supply.

Insular lobe epilepsy. Part 1: semiology

The insula is often referred to as "the fifth lobe" of the brain, and its accessibility used to be very limited due to the deep location under the opercula as well as the sylvian vasculature. It was not until the availability of modern stereo-electroencephalography (SEEG) technique that the intracranial electrodes could be safely and chronically implanted within the insula, thereby enabling anatomo-electro-clinical correlations in seizures of this deep origin. Since the first report of SEEG-recorded insular seizures in late 1990s, the knowledge of insular lobe epilepsy (ILE) has rapidly expanded. Being on the frontline for the diagnosis and management of epilepsy, neurologists should have a precise understanding of ILE to differentiate it from epilepsies of other lobes or non-epileptic conditions. Owing to the multimodal nature and rich anatomo-functional connections of the insula, ILE has a wide range of clinical presentations. The following symptoms should heighten the suspicion of ILE: somatosensory symptoms involving a large/bilateral cutaneous territory or taking on thermal/painful character, and cervico-laryngeal discomfort. The latter ranges from slight dyspnea to a strong sensation of strangulation (laryngeal constriction). Other symptoms include epigastric discomfort/nausea, hypersalivation, auditory, vestibular, gustatory, and aphasic symptoms. However, most of these insulo-opercular symptoms can easily be masked by those of extra-insular seizure propagation. Indeed, sleep-related hyperkinetic (hypermotor) epilepsy (SHE) is a common clinical presentation of ILE, which shows predominant hyperkinetic and/or tonic-dystonic features that are often indistinguishable from those of fronto-mesial seizures. Subtle objective signs, such as constrictive throat noise (i.e., laryngeal constriction) or aversive behavior (e.g., facial grimacing suggesting pain), are often the sole clue in diagnosing insular SHE. Insular-origin seizures should also be considered in temporal-like seizures without frank anatomo-electro-clinical correlations. All in all, ILE is not the epilepsy of an isolated island but rather of a crucial hub involved in the multifaceted roles of the brain.

Utilizing Multi-Source Datasets for the Reconstruction and Prediction of Water Temperature in Lake Miedwie (Poland)

Water temperature is a fundamental parameter of aquatic ecosystems. It directly influences most processes occurring within them. Hence, knowledge of this parameter’s behavior, based on long-term (reliable) observations, is crucial. Gaps in these observations can be filled using contemporary methodological solutions. Difficulties in reconstructing water temperature arise from the selection of an appropriate methodology, and overcoming them involves the proper selection of input data and choosing the optimal modeling approach. This study employed the air2water model and Landsat satellite imagery to reconstruct the water temperature of Lake Miedwie (the fifth largest in Poland), for which field observations conducted by the Institute of Meteorology and Water Management—National Research Institute ended in the late 1980s. The approach based on satellite images in this case yielded less accurate results than model analyses. However, it is important to emphasize the advantage of satellite images over point measurements in the spatial interpretation of lake thermal conditions. In the studied case, due to the lake’s shape, the surface water layer showed no significant thermal contrasts. Based on the model data, long-term changes in water temperature were determined, which historically (1972–2023) amounted to 0.20 °C per decade. According to the adopted climate change scenarios by the end of the 21st century (SSP245 and SSP585), the average annual water temperature will be higher by 1.8 °C and 3.2 °C, respectively. It should be emphasized that the current and simulated changes are unfavorable, especially considering the impact of temperature on water quality. From an economic perspective, Lake Miedwie serves as a reservoir of drinking water, and changes in the thermal regime should be considered in the management of this ecosystem.

Testing the causal impact of amyloidosis on total Tau using a genetically informative sample of adult male twins.

The amyloid cascade hypothesis predicts that amyloid-beta (Aβ) aggregation drives tau tangle accumulation. We tested competing causal and non-causal hypotheses regarding the direction of causation between Aβ40 and Aβ42 and total Tau (t-Tau) plasma biomarkers. Plasma Aβ40, Aβ42, t-Tau, and neurofilament light chain (NFL) were measured in 1,035 men (mean = 67.0 years) using Simoa immunoassays. Genetically informative twin modeling tested the direction of causation between Aβs and t-Tau. No clear evidence that Aβ40 or Aβ42 directly causes changes in t-Tau was observed; the alternative causal hypotheses also fit the data well. In contrast, exploratory analyses suggested a causal impact of the Aβ biomarkers on NFL. Separately, reciprocal causation was observed between t-Tau and NFL. Plasma Aβ40 or Aβ42 do not appear to have a direct causal impact on t-Tau. In contrast, Aβ aggregation may causally impact NFL in cognitively unimpaired men in their late 60s.

The Forensic Service (the Case Study of the Sverdlovsk Region in the 1920s–1940s)

The paper describes the process of formation and functioning of a specialized forensic service in the Urals in order to successfully combat crime during a diffi-cult unstable transition period for the country. The authors put museum information resources and archival documents as the substantive foundation of the paper. It is emphasized that the formation of the service begins with the relocation of specialists who organize this work to Sverdlovsk from Ufa. It is noted that in the 1920s there was an urgent need for personnel training for this type of activity, in connection with which courses for the training of forensic and technical experts at the Criminal Investigation Department of the NKVD were actively developing. Attention is focused on the importance of the issue of methodological support. In the 1920s the first textbook on forensic expertise appeared in Russia. During the study period, along with the need to work with traditional traces found at the scene, there was a need to detect and remove traces and objects during research that required the use of physico‑chemical methods in laboratories, in connection with which physicists and chemical experts appeared. Thus, the use of special research methods for objects seized from accident sites began in the late 1920s. In their conclusions, the authors note that the formation of an expert forensic service was carried out on the basis of scientific justification and methodological support of methods to combat unsolved crimes.

Job insecurity and fertility: Evidence from massive lay-offs in urban China

We exploit a staggered reform of state-owned enterprises (SOEs) in the late 1990s in China to provide plausibly causal evidence that job insecurity has a first-order impact on fertility. Prior to the reform, unemployment rates were low and job security for SOE workers paralleled that of government employees. Post-reform, numerous SOE employees were laid off and their contracts were no longer permanent, but government employees continued to enjoy high levels of job security. We find that the reform caused SOE employees who retained their positions to delay having their first child by 0.718 years. The spillover effects are sizable: employees in the untargeted private sector delay starting a family by 0.387 years. Despite the importance of family lineage in China at the time, our findings indicate that the fertility response transcended mere birth timing adjustments, and decreased couples’ likelihood of having children. Specifically, the reform initially reduced the number of births by 8.4 % in the short run and had a more pronounced long-term effect on completed fertility at age 45.
