Abstract. Background: prompt recognition and identification of the causative
microorganism in acute septic arthritis of native and prosthetic joints is
vital to increase the chances of successful treatment. The aim of this study
was to independently assess the diagnostic accuracy of the multiplex
BIOFIRE® Joint Infection (JI) Panel
(investigational use only) in synovial fluid for rapid diagnosis.
Methods: synovial fluid samples were collected at the University
Medical Center Groningen from patients who had a clinical suspicion of a
native septic arthritis, early acute (post-operative, within 3 months after
arthroplasty) periprosthetic joint infection (PJI) or late acute
(hematogenous, ≥3 months after arthroplasty) PJI. JI Panel results
were compared to infection according to Musculoskeletal Infection Society
criteria and culture-based methods as reference standard. Results:
a total of 45 samples were analysed. The BIOFIRE JI Panel showed a high
specificity (100 %, 95 % confidence interval (CI): 78–100) in all patient categories.
Sensitivity was 83 % (95 % CI: 44–97) for patients with a clinical
suspicion of native septic arthritis (n=12), 73 % (95 % CI: 48–89)
for patients with a clinical suspicion of a late acute PJI (n=14), and
30 % (95 % CI: 11–60) for patients with a clinical suspicion of an
early acute PJI (n=19). Conclusion: the results of this study
indicate a clear clinical benefit of the BIOFIRE JI Panel in patients with a
suspected native septic arthritis and late acute (hematogenous) PJI, but a
low clinical benefit in patients with an early acute (post-operative) PJI
due to the absence of certain relevant microorganisms, such as
Staphylococcus epidermidis, from the panel.
River effects on sea-level rise in the Río de la Plata estuary during the past century
Authors: Piecuch Christopher G.
Published: January 2023

Abstract. Identifying the causes for historical sea-level changes in coastal tide-gauge records is important for constraining oceanographic, geologic, and climatic processes. The Río de la Plata estuary in South America features the longest tide-gauge records in the South Atlantic. Despite the relevance of these data for large-scale circulation and climate studies, the mechanisms underlying relative sea-level changes in this region during the past century have not been firmly established. I study annual data from tide gauges in the Río de la Plata and stream gauges along the Río Paraná and Río Uruguay to establish relationships between river streamflow and sea level over 1931–2014. Regression analysis suggests that streamflow explains 59 %±17 % of the total sea-level variance at Buenos Aires, Argentina, and 28 %±21 % at Montevideo, Uruguay (95 % confidence intervals). A long-term streamflow increase effected sea-level trends of 0.71±0.35 mm yr−1 at Buenos Aires and 0.48±0.38 mm yr−1 at Montevideo. More generally, sea level at Buenos Aires and Montevideo respectively rises by (7.3±1.8)×10-6 m and (4.7±2.6)×10-6 m per 1 m3 s−1 streamflow increase. These observational results are consistent with simple theories for the coastal sea-level response to streamflow forcing, suggesting a causal relationship between streamflow and sea level mediated by ocean dynamics. Findings advance understanding of local, regional, and global sea-level changes; clarify sea-level physics; inform future projections of coastal sea level and the interpretation of satellite data and proxy reconstructions; and highlight future research directions. Specifically, local and regional river effects should be accounted for in basin-scale and global mean sea-level budgets as well as reconstructions based on sparse tide-gauge records.
Causes and evolution of winter polynyas north of Greenland
Authors: Lee Younjoo J. , Maslowski Wieslaw , Cassano John J. , Clement Kinney Jaclyn , Craig Anthony P. , Kamal Samy , Osinski Robert , Seefeldt Mark W. , Stroeve Julienne , Wang Hailong
Published: January 2023

Abstract. During the 42-year period (1979–2020) of satellite
measurements, four major winter (December–March) polynyas have been
observed north of Greenland: one in December 1986 and three in the last
decade, i.e., February of 2011, 2017, and 2018. The 2018 polynya was
unparalleled in its magnitude and duration compared to the three previous
events. Given the apparent recent increase in the occurrence of these
extreme events, this study aims to examine their evolution and causality, in
terms of forced versus natural variability. The limited weather station and
remotely sensed sea ice data are analyzed combining with output from the
fully coupled Regional Arctic System Model (RASM), including one hindcast
and two ensemble simulations. We found that neither the accompanying
anomalous warm surface air intrusion nor the ocean below had an impact
(i.e., no significant ice melting) on the evolution of the observed winter
open-water episodes in the region. Instead, the extreme atmospheric wind
forcing resulted in greater sea ice deformation and transport offshore,
accounting for the majority of sea ice loss in all four polynyas. Our
analysis suggests that strong southerly winds (i.e., northward wind with
speeds greater than 10 m s−1) blowing persistently over the study
region for at least 2 d or more were required over the study region to
mechanically redistribute some of the thickest Arctic sea ice out of the
region and thus to create open-water areas (i.e., a latent heat polynya). To
assess the role of internal variability versus external forcing of such
events, we carried out and examined results from the two RASM ensembles
dynamically downscaled with output from the Community Earth System Model
(CESM) Decadal Prediction Large Ensemble (DPLE) simulations. Out of 100 winters in each of the two ensembles (initialized 30 years apart: one in
December 1985 and another in December 2015), 17 and 16 winter polynyas were
produced north of Greenland, respectively. The frequency of polynya
occurrence had no apparent sensitivity to the initial sea ice thickness in
the study area pointing to internal variability of atmospheric forcing as a
dominant cause of winter polynyas north of Greenland. We assert that
dynamical downscaling using a high-resolution regional climate model offers
a robust tool for process-level examination in space and time, synthesis
with limited observations, and probabilistic forecasts of Arctic events,
such as the ones being investigated here and elsewhere.
Maritime Power Play in the Indian Ocean and Challenges for Pakistan Navy
Authors: HABIBA UMM-E- , Abbas Syed Qandil
Published: January 2023

While broadly highlighting developing maritime power tussles underway due to cooperation and competition between and/or among regional and extra-regional maritime stakeholders in the western quadrant of the Indian Ocean the research explores multifaceted internal and external challenges that Pakistan Navy is likely to face. Mainly, challenges that have emerged with the navy’s extended role and responsibilities in the aftermath of projects like Gwadar port development and maturing of the China Pakistan Economic Corridor (CPEC) are of serious concern. For, successful completion and subsequent sustainability of these projects is highly dependent upon secured maritime zone. The internal challenges include sea blindness, budgeting constraints to infrastructural upgradation and expansion, infiltration issues that surfaced within navy and domestic security issues to the CPEC. Whereas likely external challenges are conventional threats due to technological gaps with the traditional rival i.e., Indian Navy, probability, and intensity of non-conventional hybrid maritime threats and above all growing nuclearization that could result in regional instability. To counter such a wide and diverse array of challenges frequent evaluation and assessment of war and peace time roles of Pakistan Navy is required by strategic policy makers.

Novo século, novo milênio
Authors: Giarola Flávio Raimundo
Published: January 2023

No final do século XX, a chegada de um novo milênio criou um campo fértil para profecias, previsões e conjecturas sobre o futuro. Neste cenário, em meio a todos os tipos de futurólogos, alguns intelectuais se apresentaram, buscando traçar caminhos mais seguros e confiáveis para o porvir. Neste sentido, nosso artigo analisa três intelectuais (Umberto Eco, Jacques Attali e Eric Hobsbawm) que, naquele momento, tornaram públicas suas projeções sobre o futuro. Nosso objetivo é mostrar como, dentro destes exercícios de previsões, “ontem”, “hoje” e “amanhã” se articulavam numa espécie de enredo no qual o futuro seria o ponto culminante do passado e do presente.
Na lama da história

Published: January 2023

O texto reconstrói e examina a relação com a temporalidade que informa o discurso do macroismo, força política de direita que governou a República Argentina entre 2015 e 2019. O estudo se propõe a revisar as teses presentistas ao colocar em relevo a centralidade que seguem tendo as invocações ao passado e ao futuro por sua capacidade de orientar atores individuais e coletivos e dar sentido às experiências sociais. O macrismo é relevante nesse sentido, pois buscou distinguir-se das tradicionais formações conservadoras de direita ao se apresentar como uma força pós-ideológica que defendia a necessidade de esquecer o passado para focar no presente e no futuro. No entanto, em seu discurso há também um lugar importante para representações do passado e interpretações tradicionais ou conservadoras da história nacional. Para realizar esta investigação foi construído um corpus documental composto pelas fontes tradicionais da história política e intelectual -imprensa, livros, documentos oficiais-, e pelo discurso que circula nas redes sociais -Twitter, Facebook.
Um profeta da velocidade
Authors: Tedesco Alexandra Dias Ferraz , Costa Vítor Hugo dos Reis
Published: January 2023

Esse artigo se propõe a buscar, na formação do imaginário da Inteligência Artificial dos anos 1990 e 2000, as razões sociais da construção do otimismo em relação ao futuro, com a hipótese de que disciplinas como a Inteligência Artificial lançam-se à esfera pública como produtoras de imagens de futuro poderosas o suficiente para que se tornem, na linguagem popular, um tipo de consciência histórica adequada ao neoliberalismo, examinando o caso exemplar de Raymond Kurzweil. Inicialmente, serão abordados alguns pressupostos da cultura sci-fi na qual se formam esses discursos. Depois, será dada uma atenção à discussão da importância da biografia do profeta, Kurzweil, na intenção de analisar a importância do tema do guru fundador, do profeta, na construção social do otimismo com a tecnologia junto com a nova ideia de personalidade. Em seguida, serão analisados, a partir dos pressupostos anteriores, as modalidades de consciência histórica que se propagam através deles: o agenciamento de si no futurismo, a questão da tecnologia e o tipo de relação entre destino histórico e destino individual. Nossa hipótese é que os futuristas não são os profetas do futurismo, mas do atualismo, e de que a construção e a fortuna pública desse imaginário tem como coluna espinhal a ideia de que a biografia de um indivíduo exemplar é nada menos do que uma reprodução em micro escala da biografia do mundo.
“Atualismo” de Pereira & Araújo
Authors: Cardoso Jr. Helio Rebello
Published: January 2023

“Atualismo” ou “historicidade atualista” é um conceito que se tornou parte da teoria da história recente. Tal conceito desenvolve-se em duas etapas. Em primeiro lugar, ele apresenta caráter histórico-transcendental, no sentido de que envolve condições de possibilidade segundo as quais o tempo pode ser historicamente experienciado na contemporaneidade. Em segundo lugar, ele é uma ferramenta heurístico-historiográfica, no sentido de que permite reunir e analisar sob um foco conceitual bem determinado experiências históricas atualistas. Assim sendo, é possível observar que a salvaguarda transcendental heideggeriana à qual recorrem Pereira e Araujo é uma forma de preservar a função heurística do conceito, impedindo que ele se confunda com a realidade sob sua extensão. Em consequência, a crítica de Pereira e Araujo com relação ao “presentismo” de Hartog como conceito heurístico-historiográfico é discutida, no entanto, ressalva-se que essa crítica não pode ser estendida ao “presente amplo” de Gumbrecht.
COMPARISON OF BUNGEE-AIDED AND FREE-BOUNCING ACCELERATIONS ON TRAMPOLINE

Published: January 2023

Trampolines remain the single best apparatus for the training of aerial acrobatics skills.  Trampoline use has led to catastrophic injuries from poor landings.  Passive injury prevention countermeasures such as specialized matting have been largely ineffective.  Active injury countermeasures such as hand spotting, “throw-in” mats, and overhead spotting rigs provide the most effective methods.  The recent addition of several bungee cords between the ropes and the gymnast’s spotting harness has resulted in altered teaching and coaching of trampoline-related acrobatics.  Bungee cords have eliminated the need for a coach/spotter to manage the ropes during skill learning.  The purpose of this study was to assess the influence of the addition of bungee cords with a traditional rope-based overhead spotting rig.  There is a paucity of any research involving trampoline injury countermeasures.  Ten experienced trampoline acrobatic athletes (5 males, 5 females) from the U.S. Ski and Snowboard Association Aerials National Team performed 10 bounces as high as they could control.  A triaxial accelerometer (200 Hz) characterized 10 bungee cord aided bounces and 10 free-bounces on a trampoline from each athlete.  Bed contact times, peak accelerations, and average accelerations were obtained.  The results supported our hypotheses that the bungee-aided bounces achieved only 40% (average) to 70% (peak) of the free-bouncing accelerations (all ρ < 0.001 and all ƞ2partial >0.092).  The bed contact time was approximately 65% longer during the bungee-aided bounces (ρ < 0.001).  Bungee cords may reduce the harshness of landings on trampoline.

Published: January 2023

Consumerism is a buzzword of the modern lingua-Franka. In the contemporary age, human beings are generally identified as consumers. It refers to the fundamental idea of consumption- tangible and intangible substances, to frame the reference point for modern man to identify himself in terms of what he consumes. In this context, the paper explores the phenomenon of consumerism as an indispensable column of the modern hegemonic order which is neo-liberal, capitalistic and globalized. The paper then highlights the issue of identity crisis vis-à-vis consumer behavior. The paper discusses the fundamentals of Islamic world view vis-à-vis the inter-relationship of the elements of the cosmos and its nature. It delves into the deeper meanings of the Quranic concepts like khilafah, ‘ubudiyyah etc. and their implications on the identity formation of a Muslim and hence the formation of specific behavior. It tries to critically evaluate the tectonic phenomenon of consumerism from the perspective of maqasid al-Shari‘ah (the higher intents of the Islamic law) and finally proposing Islamic viewpoint to ensure civilizational renewal of the humanity, which is more natural and helps to construct a positive relationship with the self and the outer cosmos, coupling the human interests with maqasid al-Shari‘ah. The paper finally offers some policy recommendations to suggest a way towards a reformed engagement with the cosmos as a whole in terms of justice and fairness.

Published: January 2023

The purpose of this study is to demonstrate the impact of Islamic regal leadership on zakat delivery to asnaf (a group of people deserving of zakat) in Perlis. Bestowed with the constitutional authority over the state’s Islamic administration (including zakat), the regal leadership plays an important role in the effective delivery of zakat in alleviating the poor from poverty and destitution. In this article, the role of regal leadership is demonstrated through the efforts of Crown Prince of Perlis Tuanku Syed Faizuddin Putra Jamalulail. This article argues that His Royal Highness’s role in zakat delivery has been governed by close adherence to the  constitution, Islamic law, as well as Islamic principles of effective governance, all of which towards benefiting the poor.This study adopted a qualitative approach where data is collected through indepth interviews with state religious officials and 30 respondents representing the state’s zakat recipient. The findings of this study revealed that Islamic regal leadership had a significant impact on the livelihood of asnaf in Perlis, yielding positive snowballing effects while opening tremendous opportunitiesand potential for the poor to finally transition out of poverty.

Authors: Dimitrova Tatyana
Published: January 2023

The palynological analysis of the Fosso Bianco section is based on the data obtained from 23 samples. Most of the samples contain polydominant and very rarely monodominant forest components. The palynological documentation is based on a classification of some well-known paleoflora groups. The comparative characteristics of the pollen spectra are based mainly on the data of the boundary Pliocene/Pleistocene in Central Italy.

Authors: Budurov Kiril , Zagorchev Ivan , Trifonova Ekaterina , Petrunova Lyudmila
Published: January 2023

The section of the Iskur Carbonate Group (Spathian-Norian) in the Vlahina Mountain is the southernmost occurrence of the peri-Tethyan (Balkanide type) Triassic in Southwest Bulgaria. Considerable lateral facies differences are recorded. A new Boychovtsi Member of the Lyubash Formation is introduced here for the first time. It is based upon the interbedding of limestones and marls with shales, and embraces the uppermost parts of the Spathian Stage and lower parts of the Anisian Stage. The Boychovtsi Member of the Lyubash Formation covers the thin variegated interbedding of the Svidol Formation, and is covered either by the Mogila Formation (section Boychovtsi) or directly by dolomites of the Bosnek Formation.
Late Eocene to Early Miocene depositional environments of the Mesohellenic Basin, North-Central Greece: Implications for hydrocarbon potential
Authors: Zelilidis Avraam , Kontopoulos Nikolaos , Avramidis Pavlos , Bouzas Dimitris
Published: January 2023

Late Eocene to Early Miocene Mesohellenic Basin deposits accumulated in a tectonically controlled basin with irregular and narrow shelves. The boundaries between the Eocene-Oligocene Krania-Eptachori Formations and the Oligocene-Miocene Eptachori-Pentalophos Formations record the global sea-level falling during the corresponding time intervals. The sediments of the Mesohellenic Basin have characteristics of lowstand fan deposits without coastal onlap. It is suggested that the concept of the hydrocarbon habitat is applicable to the Mesohellenic Basin due to the following characteristics of the studied deposits: (a) The outer fan sandstones lobes, classified in this work as suprafan lobes, are characterized by stacked channel sand bodies with good lateral and vertical communications. These features constitute excellent reservoir facies. (b) The fme-grained, lobe-fringe and basin-plain deposits of the studied marine turbidites may have operated as either fertile source rocks or topseals. (c) The geometry ofthe lobes (stacked channel sand bodies) and the internal unconformities (between the four formations) present excellent stratigraphic traps. (d) The synchronous evolution of these deposits assures the timely relationship among all factors listed above. Since the studied sediments correspond mostly to the western margin deposits it is very possible that basinwards, in the direction of the progradation, the interchannel deposits must laterally pass into, the outer fan sandstone lobe, lobe fringe and basin plain deposits. Therefore, sediments of the basin interior not presently exposed are very likely to support favourable conditions for petroleum play.
Paleozoic continental slope deposits in the Stara Planina Mountains, Eastern Serbia
Authors: Maslarević Ljubinka , Krstić Branislav
Published: January 2023

Paleozoic (Devonian) marine sediments of the Inovo Formation in the Stara Planina Mountains consist of various metaclastic rock varieties: from conglomerates to siltstones and shales, composed of quartz, feldspar, rarely mica and abundant fragments of magmatic acid and basic rocks and intraclasts. On the basis of numerous typical sedimentary structures and textures, the clastics are interpreted as continental (lower or base of) slope deposits, resulting from a variety of mass gravity transports, viz.: debris flow, turbidity current, density-modified grainflow, and grain flow, intermittently combined with traction currents or laminar flows. In some intervals of its history, the continental slope became unstable due to tectonic movements which led to massive submarine sliding, slumping and tearing away of extrabasinal and intrabasinal blocks and olistoliths which slipped down the slope and mostly, by the debris flow mechanism, deposited with normal hemipelagic sediments.
The Villafranchian Mammalia fauna and its investigation in Europe, on the Balkans and in Bulgaria
Authors: Spassov Nikolai
Published: January 2023

The mammalian fauna of the transition from Pliocene to Pleistocene (usually designated as Villafranchian fauna) is of considerable interest. The first signs of formation of the recent Palearctic fauna should be looked for namely among the Villafranchian one. Because of the fragmentariness of most of the finds and the uneven research degree of different regions, the Villafranchian "Stage" in the mammalian fauna's development remains still insufficiently clarified. The investigations of the Villafranchian fauna are more detailed in W Europe. Corresponding investigations in SE Europe are still more incomplete. Greece and Romania are the only countries of SE Europe with well studied Villafranchian localities. Almost no mammalian megafaunas of that time have been known in Bulgaria so far. Two Bulgarian localities have been recently discovered – Varshets and Slivnitsa. Their investigation has resulted a great richness of vertebrate fossils, so that now they could be placed among the marker localities of Villafranchian fauna within E Europe. Further investigation of the Villafranchian faunistic complexes on the Balkans would considerably contribute to clearing up the migratory routes, the forming and the evolution of this fauna throughout Europe. However, zoogeographical differences are quite probable, thus the biostratigraphic criteria created in W Europe should be applied with a certain attention for the Eastern regions of the continent and especially in the Palearctic areas to the East of Europe.

We present the results of twisted plasma waves driven by twisted ponderomotive force. With the beating of two, co-propagating, Laguerre-Gaussian (LG) orbital angular momentum (OAM) laser pulses with different frequencies and also different twist indices, we can obtain the twisted ponderomotive force. Three-dimensional particle-in-cell simulations are used to demonstrate the twisted plasma waves driven by lasers. The twisted plasma waves have an electron density perturbation with a helical rotating structure. Different from the predictions of the linear fluid theory, the simulation results show a nonlinear rotating current and a static axial magnetic field. Along with the rotating current is the axial OAM carried by particles in the twisted plasma waves. A detailed theoretical analysis of twisted plasma waves is also given.

Complex perovskite oxides exhibit extremely rich physical properties in terms of magnetism, electrical transport, and electrical polarization characteristics due to the competition and coupling of many degrees of freedom. The B-site ions and O ions in perovskite form six-coordinated octahedral units, which are connected at a common vertex toward the basic framework of the perovskite oxide, providing a crucial platform to tailor physical properties. The rotation or distortion of the oxygen octahedra will tip the competing balance, leading to many emergent ground states. To further clarify the subtle relationship between emergent properties and oxide octahedral behavior, this article reviews the structure of perovskite oxides, the characterization methods of oxygen octahedral rotation and the response of transport, electrical polarization and magnetism of several typical perovskite heterostructures to oxygen octahedral rotation modes. With knowledge of how to manipulate the octahedral rotation behavior and regulate the physical properties of perovskite oxides, rationally designing the sample manufacturing process can effectively guide the development and application of novel electronic functional materials and devices.
