Działalność polityczna Antoniego Pułaskiego w czasach Rady Nieustającej (1776–1786)
Authors: Filipczak Witold
Published: December 2022

Antoni Pułaski, brat Kazimierza – bojownika o niepodległość Stanów Zjednoczonych, jest znany historykom przede wszystkim ze względu na działalność w konfederacjach barskiej i targowickiej. Artykuł ten dotyczy jego aktywności politycznej w czasach rządów Rady Nieustającej. A. Pułaski po powrocie do Polski, który nastąpił jesienią 1775 r., związał się początkowo ze stronnictwem regalistycznym. Jednocześnie Pułaski utrzymywał przyjazne stosunki z hetmanem wielkim koronnym Franciszkiem Ksawerym Branickim, czołową postacią opozycji magnackiej. A. Pułaski trzy razy (1778, 1784, 1786) pełnił funkcję posła na sejm, lecz jedynie w 1778 r. wykazał się aktywnością w czasie obrad. W kadencji 1780–1781 był deputatem, czyli sędzią zasiadającym w Trybunale Koronnym, ale jego ówczesna działalność była negatywnie oceniana przez króla Stanisława Augusta i jego współpracowników. Aktywność polityczna Pułaskiego dotyczyła przede wszystkim sejmików. W 1776 r. kierował on obradami sejmiku przedsejmowego w Czersku na Mazowszu. W następnych latach działał na Wołyniu – na sejmikach we Włodzimierzu Wołyńskim i Łucku. W latach osiemdziesiątych XVIII w. Pułaski stopniowo oddalał się od stronnictwa dworskiego i coraz wyraźniej współpracował z opozycją magnacką. Szczególnie istotną rolę odegrał w czasie burzliwych sejmików województwa wołyńskiego przed sejmem z 1786 r.
Absolutystyczny zamach stanu w Sztokholmie w 1789 r. w świetle doniesień „Pamiętnika Historyczno-Polityczno-Ekonomicznego”
Authors: Anusik Zbigniew , Karkocha Małgorzata
Published: December 2022

W artykule autorzy przybliżają kwestie związane z zamachem stanu dokonanym przez króla Szwecji Gustawa III w czasie obrad Riksdagu w 1789 r., który pozwolił mu skupić pełnię władzy w swoim ręku. W pierwszej części opracowania omówiono pokrótce poczynania Gustawa III w latach 1771–1788. Zwrócono uwagę na powolne odchodzenie przez króla od zasad oktrojowanej przez niego konstytucji z sierpnia 1772 r. Kiedy zaś władca Szwecji zdecydował się zaatakować Rosję w końcu czerwca 1788 r., ściągnął na siebie poważne kłopoty. W armii doszło bowiem do buntu części oficerów, którzy sprzeciwili się wojnie rozpoczętej bez zgody Riksdagu. Gdy zaś do wojny po stronie Rosji przyłączyła się Dania, wydawało się, że nic nie uratuje Gustawa III od klęski. Stało się jednak inaczej. Interwencja dyplomatyczna Wielkiej Brytanii powstrzymała wojska duńskie. Korzystając natomiast z poparcia trzech niższych stanów, król w czasie Riksdagu 1789 r. zmusił szlachtę do posłuszeństwa, dokonał zamachu stanu i rozprawił się z buntem w armii. Wszystkie wydarzenia w Szwecji z lat 1788–1789 zostały szczegółowo omówione w wydawanym przez Piotra Świtkowskiego „Pamiętniku Historyczno-Polityczno-Ekonomicznym”. Na podkreślenie zasługuje fakt, że Świtkowski odnosił się z wielką sympatią do władcy Szwecji i w pełni zaaprobował wzmocnienie jego władzy kosztem przywilejów szlacheckich. Artykuły zamieszczane w czasopiśmie Świtkowskiego dawały czytelnikom dobre wyobrażenie o sytuacji w Szwecji w 1788 i 1789 r. W zakończeniu opisano pokrótce poczynania Gustawa III po roku 1789 aż do zamachu na jego życie i śmierci władcy w dniu 29 marca 1792 r.
Dyskurs historiograficzny wokół służby wojskowej Tadeusza Kościuszki w latach 1790–1792
Authors: Srogosz Tadeusz
Published: December 2022

Życie i działalność Tadeusza Kościuszki były przedmiotem zainteresowania zarówno profesjonalnych historyków, jak również innych autorów, którzy podejmowali tematy związane z postacią Naczelnika. Wydarzenia z bogatego życia Kościuszki stały się niejednokrotnie przedmiotem gorących sporów, jednak o mniejszym natężeniu wokół jego służby wojskowej w latach 1790–1792. Jeszcze w XVIII w. zaczął się spór o Kościuszkę, który był podstawą do rekonstrukcji wydarzeń i ocen przez historyków. Mimo zgłaszanych przez poszczególnych autorów deklaracji, dyskurs historiograficzny nie miał zwykle cech neutralności, a raczej górowały często emocje czy rocznicowe publikacje. Ponadto w historiografii występują niekonsekwencje, na przykład w sprawie stosunku Kościuszki do systemu kordonowego.
Bolesław Prus – nie tylko prozaik. Sylwetka filantropa
Authors: Kiełb Ewa , Robak Piotr
Published: December 2022

Artykuł odnosi się do postaci Bolesława Prusa, wybitnego pisarza okresu pozytywizmu. W tekście uwypuklony został mniej znany aspekt jego biografii, a mianowicie zainteresowanie działalnością dobroczynną. Kwestia ta jest zazwyczaj traktowana jako zagadnienie drugoplanowe. Jeszcze rzadziej wspomina się o związanej z nią, stworzonej przez Prusa, teorii dotyczącej społeczeństwa, postępu, jak też o Prusowskich poglądach na wychowanie i sprawy upowszechniania kultury, czy roli sztuki w życiu narodu.

Zgromadzony materiał, tj. fragmenty korespondencji pisarza, wypowiedzi publicystyczne, a ponadto przywołane przykłady, świadczące o osobistym zaangażowaniu Prusa w prace filantropijne (aktywność w ramach towarzystw, wspieranie projektów na rzecz potrzebujących, popularyzowanie szlachetnych idei pomocy słabszym), ukazuje, z jakim oddaniem Prus podchodził do spraw społecznych. Jego działalność w tym zakresie zobrazowana została w artykule na przykładzie Warszawy oraz Lublina i okolic. W tych miejscach Prus zapisał się jako człowiek szczerze popierający inicjatywy służące osobom, które wymagały pomocy materialnej lub lekarskiej, serdecznie odnosił się do wszystkich gotowych nieść tę pomoc w trudnych warunkach zaboru rosyjskiego na przełomie XIX i XX w.
Bajończycy – pierwsza polska jednostka walcząca na froncie zachodnim w latach 1914–1915
Authors: Jarno Witold
Published: December 2022

Artykuł opisuje dzieje polskiej kompanii walczącej na froncie zachodnim w latach 1914–1915 w składzie francuskiej Legii Cudzoziemskiej. Oddział ten przeszedł do historii jako Bajończycy, bądź Legion Bajończyków, a swą nazwę wziął od miejscowości Bayonna, w której został sformowany. Był to pierwszy oddział polskich ochotników walczący po stronie państw Ententy. Stał się on symbolem polskich dążeń niepodległościowych, walcząc na polach Szampanii w początkowym okresie I wojny światowej.
„Niewola kobiet” jako przedmiot refleksji ruchu młodowiejskiego w II Rzeczypospolitej
Authors: Lech Andrzej
Published: December 2022

Celem artykułu jest ustalenie roli ruchu młodowiejskiego, jako autonomicznej części polskiego ruchu ludowego, w działaniach emancypacyjnych na rzecz kobiety wiejskiej w okresie II Rzeczypospolitej. Ruch ten zintegrowany wokół Związku Młodzieży Wiejskiej Rzeczypospolitej („Wici”) w latach 1928–1939, podjął pionierskie w środowisku społecznym wsi działania na rzecz wydobycia kobiety z tzw. niewoli tradycyjnego patriarchatu. Było to trudne zadanie w rzeczywistości zacofanej cywilizacyjnie międzywojennej wsi. Na treść artykułu składają się trzy części merytoryczne. Najpierw zaprezentowano materiał pozwalający na charakterystykę wizerunku krzywdzonej niewiasty. Następnie opisano wpływ patriarchatu na jej uprzedmiotowienie, m.in. poprzez stosowanie wobec niej przemocy fizycznej i psychicznej. Na koniec poddano analizie dokumenty programowe ruchu młodowiejskiego dotyczące rozwiązania tzw. kwestii kobiecej w wizji agrarystycznej. Ich celem było doprecyzowanie kierunku działalności emancypacyjnej, przejętych nadzieją, że kobieta wiejska stanie się jednostką w pełni kreatywną, świadomą swej podstawowej roli w życiu rodziny, wsi i państwa, że będzie dobrze przygotowana do twórczego udziału w budowie nowej, sprawiedliwej społecznie i demokratycznej, ludowej Polski.
Kilka uwag na temat nauczania historii
Authors: Jasitczak Joanna
Published: December 2022

Specyfika młodego pokolenia przesiąkniętego elektroniką, przyzwyczajonego do wartkiego, dynamicznego przekazu stawia przed nauczaniem historii nowe wyzwania. Niechęć do korzystania z podręczników, literatury fachowej jest coraz większa. Tym bardziej, że pojawiła się alternatywa w postaci materiałów publikowanych na portalach społecznościowych, platformach streamingowych. Uczniowie coraz chętniej sięgają po tego typu rozwiązania. To zjawisko będzie eskalować. Nauka przez Internet budzi jednak obawy i kontrowersje. Główne zagrożenie dotyczy braku kontroli nad publikowanymi treściami, co podaje w wątpliwość ich wartości merytoryczne. Można z jednej strony protestować wobec takiego stanu rzeczy, z drugiej można Internet wykorzystać jako klucz do zainteresowania młodzieży szkolnej tematami naukowymi w przystępny sposób. Tym samym sprawić, by uczeń zechciał zgłębić temat. Wymaga to jednak od pedagoga pewnego nakładu pracy, jak i wysiłku związanego z koniecznością zaznajomienia się z terra incognita pod postacią środowiska social mediowego. Celem takiego działania jest możliwość rekomendowania uczniom materiałów godnych uwagi oraz przestrzegania przed publikacjami o wątpliwej wartości poznawczej.

Discurso, identidad y género en el castellano peruano
Authors: De los Heros Diez Canseco Susana
Published: December 2022

El objetivo principal del presente libro es iniciar un diálogo sobre la influencia del género de los hablantes en el uso del castellano en el Perú. Con esto en mente, presentaremos una serie de estudios sobre el castellano de Cuzco y de Lima en los que analizamos y discutimos de qué manera el género de los hablantes influye en la variación del castellano y en el uso de distintas estrategias conversacionales en Lima y en Cuzco. También examinamos cómo los hablantes pueden manejar la lengua para construir una identidad o una imagen que esté de acuerdo con su género. En otras palabras, se analiza la variación del discurso de acuerdo al género/sexo del hablante para apreciar que los hablantes femeninos y masculinos construyen o más bien presentan y representan una imagen discursiva de acuerdo a su género/ sexo.

Retratos familiares
Authors: Sumalavia Ricardo
Published: December 2022

En «Habitaciones», su primer libro de cuentos, Ricardo Sumalavia nos mostró un universo peculiar, construido por historias fragmentadas, instantes de sugerencia y revelación. Ahora, ese universo peculiar en nuestra narrativa se ve ampliado en la presente obra, una nueva exploración de los hombres que transitan por una ciudad tan real como imaginaria, una presencia dominante que somete a los protagonistas a vivir experiencias inusitadas, donde el misterio y la ambigüedad se nos presenta como algo cotidiano, sin dejar de contener una perturbadora atracción. Sumalavia ofrece al lector no solo unos argumentos conmovedores, sino el encuentro con una estética narrativa que quiebra las convenciones del relato y se debate, constantemente, en los límites de toda convención literaria, alejándose así de todos para asumir una voz propia e inigualable dentro de nuestra literatura.

Published: December 2022

Nanoparticles are widely used in medical diagnosis and treatment, as carriers of drug preparations, in cosmetics, production packaging and transportation of foods and etc. Special attention is paid to the use of biological structures in the production of nanoparticles. The aim at the presented work was to investigate the influence of temperature on the formation of silver nanoparticles by Candida macedoniensis BSU-MI44. Wet biomass of yeast at AgNO3 solution, was incubated at 25, 30, 35, 40°C. The samples have been analyzed on the UV spectrometer, the scanning electron microscope and the X-ray spectroscope. Spectrophotometric analyses showed 410 nm wavelength (peak), characteristic for silver nanoparticles in samples incubated at 25 and 30°C. By increasing temperature, the formation of silver nanoparticles has weakened and has finally stopped. The optimum temperature was between 25-30°C for the production of silver nanoparticles and the formed nanoparticles were spherical at both temperatures. The sizes of silver nanoparticles formed at 25°C and 30°C were 65.6 and 14.2-22.9 nm. The sizes of the first ones have been 2.8-4.7 times larger than the sizes of the others. Correspondingly X- ray spectroscopic analyses of the obtained samples showed the characteristic absorption peak for silver nanoparticles formed at temperatures 25 and 30°C.

This study aims is to examine the degree of satisfaction among students in the preparatory year at the Prince Sattam Bin Abdul Aziz University (PSAU) and Imam Abdul Rahman Bin Faisal University (IAU) regarding the virtual lessons and educational platforms during the 2019 coronavirus pandemic. It focused on the educational services provided through educational platforms and virtual lessons especially those that replaced traditional lessons during the pandemic period as an alternative option for continuing the educational process and the difficulties they faced during the pandemic. The sample represented a transitional stage between secondary and university education and the results were based on the opinions provided by males, females and students with disabilities. In addition, the study relies on a descriptive and analytical approach and contains 31 questions that were given to 276 undergraduate students. It was found that the virtual lessons through the educational platforms were a good solution for the students because they saved time and effort and supported students with disabilities. The results also showed that 78.5% expressed satisfaction with using virtual lessons and educational platforms which indicates the success of the process of transitioning to distance education during the COVID-19 pandemic. The two universities were recommended to make the necessary improvements.

Authors: Yuanmeng Guo
Published: December 2022

International trade is increasing due to the rapid development of globalization. Many businesses target foreign markets, so trademark translation plays an important role in the promotion and sales of goods in those foreign markets. Skopos theory provides strong theoretical support for trademark translation. This paper examines the manifestation of the three principles of the Skopos theory in trademark translation and discusses the guiding role of the Skopos theory for trademark translation strategy from four aspects: literal translation, transliteration, transliteration and translation, and conversion. At the same time, it explores the practical significance of trademark translation and provides a reference for future trademark translation practice.

The South Atlantic Coastal Study (SACS) was completed by the US Army Corps of Engineers to quantify storm surge and wave hazards allowing for the expansion of the Coastal Hazards System (CHS) to the South Atlantic Division (SAD) domain. The goal of the CHS-SACS was to quantify coastal storm hazards for present conditions and future sea level rise (SLR) scenarios to aid in reducing flooding risk and increasing resiliency in coastal environments. CHS-SACS was completed for three regions within the SAD domain, and this report focuses on the Coastal Hazards System–Puerto Rico and US Virgin Islands (CHS-PR). This study applied the CHS Probabilistic Coastal Hazard Analysis (PCHA) framework for quantifying tropical cyclone (TC) responses, leveraging new atmospheric and hydrodynamic numerical model simulations of synthetic TCs developed explicitly for the CHS-PR region. This report focuses on documenting the PCHA conducted for CHS-PR, including the characterization of storm climate, storm sampling, storm recurrence rate estimation, marginal distributions, correlation and dependence structure of TC atmospheric-forcing parameters, development of augmented storm suites, and assignment of discrete storm weights to the synthetic TCs. As part of CHS-PR, coastal hazards were estimated for annual exceedance frequencies over the range of 10 yr⁻¹ to 10⁻⁴ yr⁻¹.
An Adaptive Moth Flame Optimization Algorithm with Historical Flame Archive Strategy and its Applications
Authors: Wang Zhenyu , Cao Zijian , Jia Haowen
Published: December 2022

The rule-based network intrusion detection system (IDS) is every effective and efficient for protecting the network equipment and avoiding suffering cyberattack. However, its rule generation is a NP-hard problem, which cannot be solved well by mathematical methods. Moth Flame Optimization (MFO) is a new nature-inspired heuristic algorithm, and has successfully been utilized to solve the various complex practical engineering problems. To effectively provide the rule of IDS, an adaptive MFO algorithm with historical flame archive strategy is proposed in this paper for enhancing exploitation of MFO and avoiding dropping into local optimal trap, which is termed MFO-HFA to avoid ambiguity. In MFO-HFA, to make effectively population escape local optimal trap, the archive consists of historical optimal individuals, which is utilized to preserve the information of better historical flame. Besides, to improve the convergence ability of the algorithm, a top flame randomly matching mechanism is utilized to make full use of the information of top flame. To demonstrate the advantage of MFO-HFA, it is compared with several well-known variants of MFO and some state-of-the-art intelligence algorithms on both 25 benchmark functions of CEC 2005. The experimental results indicate that MFO-HFA outperforms other compared algorithms and has obtained best accuracy. Furthermore, MFO-HFA is used to generate the rule of IDS by NSL-KDD dataset. The test results demonstrate that MFO-HFA outperforms compared algorithms and has gained 96.5% accuracy.
New expanding cavity model for conical indentation and its application to determine an intrinsic length scale of polymeric materials
Authors: Sevastyanov Georgiy
Published: December 2022

New expanding spherical cavity model (ECM) for conical indentation is proposed. For polymeric materials description, the model incorporates isotropic non-monotonic strain-hardening. For capturing the indentation size effect (ISE), the model incorporates the strain gradient dependence in yield strength based on lower-order strain gradient plasticity assumptions. Specifically, the forward gradient of the equivalent (accumulated) plastic strain is utilized as a non-local part of the yield strength. To predict the indentation depth-dependent hardness based on the proposed model, it is sufficient to numerically integrate one nonlinear ODE of the first order, and then calculate the definite integral. For the local plasticity model, the hardness is obtained as an analytical expression that differs from known ECMs. The hardness estimate obtained numerically using the proposed model is compared with the experimental ISE data for polycarbonate (PC) and polymethyl methacrylate (PMMA). For the local plasticity model, the formula obtained in the study is compared with the experimental data on the hardness of preliminary workhardened materials. In both cases, the model shows good agreement with the experimental data. Fitting the experimental data on ISE, we found that intrinsic length scale of PMMA should be near 3 micron and near 9 micron for PC.
Tingbjerg Changing Diabetes: Experiencing and navigating complexity in a community-based health promotion initiative in a disadvantaged neighborhood in Copenhagen, Denmark
Authors: Termansen Tina , Bloch Paul , Tørslev Mette Kirstine , Vardinghus-Nielsen Henrik
Published: December 2022

As a response to the complexity of reducing health inequity there has been a rise in community-based health promotion interventions adhering to the principles of complexity thinking. Such interventions often work with adaptive practice and constitute themselves in complex webs of collaborations between multiple stakeholders. However, few efforts have been made to articulate how complexity is experienced by stakeholders or can be addressed in practice. This study explores how partners experience and navigate complexity in the partnership behind Tingbjerg Changing Diabetes (TCD), a community-based intervention addressing health and social development in the disadvantaged neighborhood of Tingbjerg in urban Copenhagen. The study is based on 18 months of ethnographic fieldwork in the local community including participant observations and 9 in-depth interviews with key partner representatives. Findings show that complexity in TCD can be characterized by unpredictability in actions and outcomes, undefined purpose and direction, and differing organizational logics. Factors that support partners’ navigation in complexity include connectivity, embracing a flexible intervention framework, autonomy, and quick responsiveness. The study showcases the interdependency between the intervention and the context of the disadvantaged neighborhood of Tingbjerg and encourages stakeholders and researchers to embrace the messiness of complexity, and to pay attention to ways through which messiness and unpredictability can be handled.

Network Information Channel and Household Financial Market Participation Inequality: Evidence from China
Authors: Ji Cheng , Wang Tingting
Published: December 2022

We investigate and evaluate the influence of network information channels on inequality in household financial market participation using data from the China Family Panel Studies (2018). According to our findings, network information channels can improve the inequality of household financial market participation, and this impact stems in part from the displacement of other information channels. Then we look at whether two variables, region and family type, influence the impact of network information channels. The eastern area of China has a favorable effect on the role of network information channels, according to our findings. The western area, on the other hand, has a negative influence on the primary effect, and the negative impact only appears among households with limited financial participation opportunities. Furthermore, the impact of network information channels is unaffected by whether the family is from a rural or urban environment. These findings suggest that, in order to allow more residents to participate in financial market investment, it is necessary to pay attention to network construction, break the information barrier to participate in the financial market, and provide a good foundation for families to participate in the financial market.

Published: December 2022

With the rapid development of IoT technology, medical IoT is one of the current research focuses and hotspots. In the practical application of medical IoT, achieving accurate localization and effective data fusion is conducive to improving the operational efficiency of medical IoT and reducing the power consumption of the network. Therefore, this paper uses SVM and KNN algorithms to improve the localization accuracy, and proposes an event-driven cluster-tree data fusion algorithm DFC based on the special characteristics of data in medical IoT.The DFC algorithm uses a combined cluster-tree topology to dynamically partition clusters and decide the decision range of the corresponding cluster based on the severity of the event, and then constructs the data fusion within the cluster from the current cluster head The data propagation along the fusion tree can improve the accuracy of the data and extend the lifetime of the network. In this paper, we analyze the fusion delay problem in the network and propose a minimum fusion delay method by calculating the fusion waiting time of nodes. Experiments demonstrate that the DFC algorithm has better accuracy and fusion through machine learning, an improvement of the medical IoT. This is of great importance in real-life applications
Accurate Management of Public Services Based on Big Data
Authors: Xu Jiamuzi
Published: December 2022

With the support of national policies, information technology and resource aggregation are increasing day by day. Large-scale data mining is a large scientific and practical area of "digital gold". This is not only a challenge of the times, but also requires vigorous development of public services. Therefore, this paper was driven by big data to analyze the current situation of public services, and then used the fuzzy evaluation method to analyze the precise management. Finally, the public service management was optimized, and the realization path of the accurate management of the whole process of public service driven by big data was designed. Through fuzzy comprehensive evaluation, it was known that the model value and information entropy of public services were constantly increasing; the average value of the model value of precise management of public services was about 4.35, and the average value of information entropy was about 0.98. Moreover, the management efficiency and comprehensive efficiency of precision management of social public welfare activities based on big data were better than that of traditional precision management of public services; the management benefits were 7% higher than the traditional ones, and the overall efficiency was 9% higher than the traditional ones.
Generalization of Beckmann’s Transformation for Traffic Assignment Models With Asymmetric Cost Functions
Authors: Marechal Matthieu , Grange Louis
Published: December 2022

An optimization model is developed to solve the deterministic traffic assignment problem under congested transport networks with cost functions that have an asymmetric Jacobian. The proposed formulation is a generalization of Beckmann’s transformation that can incorporate network links with multivariate vector cost functions to capture the asymmetric interactions between the flows and costs of the different links. The objective function is built around a line integral that generalizes the simple definite integral in Beckmann’s transformation and is parameterised to ensure the solution of the new problem satisfies Wardrop’s first principle of network equilibrium. It is shown that this method is equivalent to the variational inequality approach.

Published: December 2022

Communication is the basis of UAV(Unmanned Aerial Vehicle,UAV) cluster cooperative decision control. In the battlefield environment with scarce communication resources, it is of great significance to realize the efficient communication of UAV cluster. At present, Multi-Agent Reinforcement learning method is widely used in the research of Autonomous Cooperation Strategy of UAV cluster, but most methods do not consider the impact of limited communication resources. Based on the partial observable Markov decision process, a communication based autonomous behavior decision model of UAV cluster is proposed; Based on the research hypothesis and information theory, a reward strategy based on bandwidth utilization is designed. The reward value under this strategy is adjusted with the change of available bandwidth, which can guide the UAV whether to send messages at each step in real time; In the process of model training and execution, the long-term and short-term memory network is used as the memory unit to ensure the effectiveness of UAV cooperative decision-making. The effectiveness of the proposed method is verified by air confrontation simulation experiment, which provides a method reference for autonomous cooperative decision-making of UAV cluster in bandwidth limited combat scenario.
Volatile Kernel Rootkit Hidden Process Detection in Cloud Computing
Authors: S Suresh kumar , SudalaiMuthu T
Published: December 2022

Malware assaults on kernel rootkits have grown increasingly nuanced and difficult to detect, giving them control over the functionality of the kernel. It can be difficult to detect the presence of these kernel rootkits within the victim system since they use stolen techniques to conceal the system tasks, kernel modules, and various management structures. The majority of the current rootkit detection methods are system-specific and supported by traditional sources, making them ineffectual for new, obscure, and undiscovered rootkits. In order to identify such rootkits by their distinctive hidden processes, this study suggests a VKRHPDV system. This detection method uses a cross-view, clean-boot-based approach and defines a process-watching framework that continuously keeps track of all running processes and can identify any rumoured or unidentified rootkit with the least amount of performance overhead. The linguistics gap is filled by VKRHPDV, which monitors the kernel while extremely discretely intercepting call events of the tainted package to reconstruct a semantic-level method information structure. The results of an in-depth performance analysis performed on sixty-four rootkit datasets in a cloud environment for each UNIX and Windows kernel show that VKRHPDV can detect process hiding habits in all datasets in the shortest amount of time.

Authors: Maddu Sujatha , Srivast Tanu , Katari Naresh Kumar , Merugu Karuna , Gundla Rambabu , S Krishna Mohan
Published: December 2022

In the present studies silicon based low density ablative material has been studied for its ablative performance to protect flight hardware from temperature raised due to aerodynamic forces for longer duration. Ablative properties are estimated by oxyacetylene flame test at 100-120 W/m2 heat flux. The time duration for the flame test is taken 200 sec. The material shows low mass and linear ablation rate with high ablative effectiveness. The degradation kinetics of silicon ablator is studied by Thermo Gravimetric Analysis (TGA) method. Non-isothermal TGA is performed in the temperature range of 30 °C to 900 °C at various heating rates viz. 5, 10, 15 and 20 oC/ min. Knowledge of the kinetic parameters of thermal decomposition is used to predict degradation kinetics of the material at high heating rates which the ablator faces during aerospace applications. During ablation the silicone ablative material consist of a virgin zone, reaction zone and char zone. These are explained by kinetic parameters which are determined with help of free software called Kinetic Calculation.

In patients with t(8;21) acute myeloid leukemia (AML) with recurrent minimal residual disease (MRD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT), pre-emptive interferon-α therapy and donor lymphocyte infusion are noneffective in 30–50% of patients. Avapritinib is a novel tyrosine kinase inhibitor targeting KIT mutations. We report about 20 patients with t(8;21) AML and KIT mutations treated with avapritinib after allo-HSCT with MRD and most failing to respond to immunotherapy. Reduction of RUNX1-RUNX1T1 transcripts after 1 month of treatment was ≥ 1 log in 12 patients (60%), which became negative in 4 patients (20%). In 13 patients who received avapritinib for ≥ 3 months, the reduction was ≥ 1 log in all patients, which became negative in 7 patients (53.8%). The median follow-up time was 5.5 (2.0–10.0) months from avapritinib initiation to the last follow-up. Three patients underwent hematologic relapse and survived. Among all 20 patients, RUNX1-RUNX1T1 transcripts turned negative in 9 patients (45%). The efficacy did not differ significantly between D816 and non-D816 KIT mutation groups. The main adverse effect was hematological toxicity, which could generally be tolerated. In summary, avapritinib was effective for MRD treatment in patients with t(8;21) AML with KIT mutations failing to respond to immunotherapy after allo-HSCT.
Seismic response characteristics and whiplash effect mechanism of continuous rigid-frame bridges subjected to near-fault ground motions
Authors: Li Jun , Xu Long-He
Published: December 2022

Continuous rigid-frame bridge (CRFB) is widely constructed in western China with high seismicity areas. To investigate the seismic response characteristics and whiplash effect mechanism of CRFBs under near-fault ground motions, this study selects a long-span CRFB with high piers as the prototype bridge and develops the nonlinear finite element model based on OpenSees. In this work, three groups of near-fault ground motions having forward directivity pulse, fling-step pulse and non-pulse are selected as seismic inputs. These records are intercepted using significant duration index and scaled to 0.2 g, 0.4 g, and 0.64 g, representing basic ground motions, frequent ground motions and rare ground motions, respectively. The study analyzes the seismic response characteristics of CRFBs and discusses the effects of bearing constraints, ground motion components and vertical excitations on the seismic responses. The numerical results show that the longitudinal vibration, transverse whiplash effect and vertical uplift behavior of main girder are main deformation characteristics of CRFBs. Compared with non-pulse earthquakes, the structural displacements, lateral drift angles, bearing deformations, internal forces and pounding effects all significantly increase under pulse-like earthquakes. There are spatial torsional effects in mid-span girder and main piers and pounding effects between girder ends and transition pier top. The perfectly-free and fixed bearings in transverse direction are not recommended for the seismic design of CRFBs. An optimal stiffness ratio in friction pendulum systems may exist that can minimize bending degree of the main girder. Furthermore, the side-span girder under pure longitudinal excitations can uplift that is closely related to the pier-girder consolidation form and rotation of the main piers. The main piers may be tensioned under strong vertical excitations, which is an uncommon problem worthy of attentions.
Estimation of uncertainty from duplicate measurements: new quantification procedure in the case of concentration-dependent precision
Authors: Synek Václav , Kříženecká Sylvie
Published: December 2022

In many analytical measurements, the analyte concentration in the test samples varies over a wide range. In such cases, the standard deviation (SD) quantifying the imprecision of the measurement should be expressed as a function of the analyte concentration, c: \({s}_{c}=\sqrt{{\text{s}}_{0}^{2}+{ s}_{r}^{2}{c}^{2}}\), where s0 represents a nonzero SD at zero concentration and sr represents a near-constant relative SD at very high concentrations. These parameters can be estimated from the differences in the values measured in duplicate on test samples; datasets with a high number of duplicate results can be obtained within the internal quality control. The procedures recommended for parameter estimation published so far are based on statistically demanding weighted regression. This article proposes a statistically less demanding procedure that estimates s0 and sr separately by processing the differences between the duplicates from areas with lower and higher concentration levels, where the terms \({ s}_{r}^{2}{c}^{2}\) and \({\text{s}}_{0}^{2}\)do not represent the dominant components of \({ s}_{c}^{2}\), respectively. The parameter estimates are calculated by using the root mean square of the differences, with an addition correction for the interfering effect of second, less significant term. This procedure was verified on Monte Carlo simulated datasets. The variability of the parameter estimates obtained by this simpler procedure was similar to or slightly worse than that of the estimates obtained by the best but statistically demanding regression procedure, but better than the variability of the estimates obtained by the other tested regression procedures.
Partition of Omega facility in two configurations of 24 and 36 laser beams to improve implosion performance

Published: December 2022

The OMEGA installation is separated into two independent sub-configurations with 24 and 36 laser beams each one minimising direct drive illumination non-uniformity. Two different laser focal spots associated one to each configuration are proposed to apply the zooming technique in order to increase the laser-target coupling efficiency. This approach is used by 1D hydrodynamics simulations of the implosion of a direct-drive capsule characterised by a relatively large aspect ratio A = 7 and an optimized laser pulse shape delivering a maximum of 30 TW and 30 kJ. It is shown that zooming allows for a 1D-thermonuclear energy gain greater than one while without zooming the thermonuclear gain remains largely below one.

Published: December 2022

Forty-six samples of urban topsoil were collected from Tripoli at a depth of 0–15 cm to determine the concentration of nine heavy metals, including Cd, Pb, Zn, Cu, Ni, Co, Fe, Mn, and Cr. The study aimed to quantify and identify their likely sources of environmental contamination indices and assess their ecological risk to humans. The mean concentrations of these metals were 3.943, 38.317, 170.941, 29.669, 19.699, 30.371, 27444.515, 235.812, and 195.92 mg.kg-1, respectively. These values are higher than the virgin soil background values and permissible limits set forth by WHO. The pollution index (PI) varied from 1.152 for Ni and 2.518 for Cr. The geoaccumulation index (Igeo) averaged 0.824 for Mn and 1.679 for Cr, the contamination factor (CF) averaged 1.28 for Mn and 2.686 for Cr, and the enrichment factor (EF) averaged 0.968 for Mn and 1.893 for Cr, respectively. Pollution indicators such as the Pollution Load Index (PLI), Contamination Degree (Cdeg), and Potential Ecological Risk (RI) suggest that the research region is moderately contaminated, with values ranging from 1.233–1.923, 12.099–18.469, and 47.241–145.067, respectively. Principal component analysis (PCA), correlation coefficient, and hierarchical cluster analysis (HCA) had used to identify the studied metals' possible sources. The results revealed that three sources of heavy metals were determined as indicated by a strong positive correlation between Cd, Pb, Cu, Cr, and Co, which suggested that the sources of these metals are mainly anthropogenic, such as agricultural practices, industrial activities, and vehicle emissions. While the possible sources of Mn, Fe, and Ni mainly originate from natural sources (parent rocks). The heavy metals' potential ecological risk was determined to be moderate. The RI ranged from 65 to 130.
Temporal word embedding with predictive capability

Published: December 2022

Semantics in natural language processing is largely dependent on contextual relationships between words and entities in a document collection. The context of a word may evolve. For example, the word ``apple'' currently has two contexts -- a fruit and a technology company. The changes in the context of words or entities in text data such as scientific publications, and news articles can help us understand the evolution of innovation or events of interest. In this work, we present a new diffusion-based temporal word embedding model that can capture short and long-term changes in the semantics of entities in different domains. Our model captures how the context of each entity shifts over time. Existing temporal word embeddings capture semantic evolution at a discrete/granular level, aiming to study how a language developed over a long period. Unlike existing temporal embedding methods, our approach provides temporally smooth embeddings, facilitating prediction and trend analysis better than those of existing models. Extensive evaluations demonstrate that our proposed temporal embedding model performs better in sense-making and predicting relationships between entities in the future compared to other existing models.

Authors: Ostapenko Hanna , Mitchell Toby , Castro-Marin Pablo , Reid Derryck T.
Published: December 2022

We report a 1-GHz repetition rate Ti:sapphire laser pumped with a single green pump diode, producing 111-fs pulses and exhibiting self-starting Kerr-lens modelocking at pump powers above 850 mW. At 1.1W of pump power, the average output of the laser is over 116 mW, and the slope efficiency of the laser is measured to be 13%. The optimisation of the cavity dispersion has demonstrated a possible shortening of the pulses up to 87 fs with an average power of 108 mW. The relative intensity noise of the laser was measured to be 0.06%, and the phase error of the repetition rate after locking to a reference has been measured to be 1.7 mrad, corresponding to timing jitter of 270 fs.
Determining equations governing multibody dynamic systems through joint kinematics and kinematic chain effects in closed-form mechanisms
Authors: Mohammadi Yousef , Fatouraee Nasser , Bostanshirin Mehdi
Published: December 2022

In this study, the governing equations of dynamic systems were derived using a novel method that integrated the kinematic properties of joints and the complex kinematic chains of multibody systems into a set of governing equations. The governing equations of multibody systems were then transformed into ODE using the calculus of matrix-valued functions. This algorithm can efficiently obtain recursive differential equations of motion for multibody systems. Consequently, the computational cost of the simulation was reduced successfully. Andrew’s squeezing and carpet scraping mechanisms were utilized with kinematic constraints to validate the proposed method. Results indicated that the proposed method was 4.2 and 5.4 times faster than the other methods based on algebraic differential equations in Andrew’s squeezing and carpet scraping mechanism, respectively.

Published: December 2022

Worldwide, organizations are migrating their IT infrastructure to public clouds. One of the biggest challenges during this transition is the implementation of appropriate security techniques to withstand cyber attacks. Unfortunately, this process is still ambiguous for many organizations and data are exposed to different threats and vulnerabilities during this migration.To address this, there are several approaches applied worldwide to strengthen security of the stored data on cloud computing. The two-fold DNA Cryptography is one such data security techniques.The existing technique focuses only on the ASCII character set, ignoring the non-English user of the cloud computing. Thus, proposing two-fold DNA Cryptography using the Unicode characters so that it can be used for non-English users also.
