10 Canol Formation, Northwest Territories, Canada—An Outcrop-to-Subsurface Analog for the Paleozoic Horn River Shale-gas Play
Authors: Potma K. , Jonk R. , Bohacs K. M.
Published: March 2024

The Late Devonian Canol Formation and associated stratal units in the Northwest Territories of Canada illustrate the expression of sequence-stratigraphic surfaces and units in a distal Paleozoic carbonate shelf to relatively deep-basin setting. These Devonian strata are time equivalent and quite analogous in depositional conditions and petroleum-system characteristics to the proven shale-gas deposits in the Horn River Basin of northeastern British Columbia.

The Canol Depositional Sequence spans the upper part of the Ramparts Formation, the Canol Formation, and the lowermost part of the Imperial Formation. This depositional sequence comprises a range of facies associations, spanning siliceous, calcareous, and argillaceous fine mudstone to sandy mudstone. Eight distinct facies associations can be identified, correlated, and mapped within the study area. These form the building blocks of a predictive understanding of the depositional system that is critical for resource identification, delineation, and development. These facies associations vary in a systematic and predictable manner both vertically and laterally within a sequence-stratigraphic framework. The strata record the interplay of intrabasin organic production (phytoplankton) and associated growth of zooplankton (mainly radiolaria and tentaculitids) versus extrabasinal detrital siliciclastic input (dominated by clay minerals), as well as input of carbonate sediment-gravity flows from pre-existing or age-equivalent platforms and buildups along the basin edges. The lowstand systems tract of the Canol Depositional Sequence contains mostly argillaceous-calcareous mudstone facies association with some transported benthic-carbonate material. The transgressive and lower highstand systems tracts contain the best reservoir potential as their composition is dominated by biogenic silica and organic matter. The upper highstand systems tract is influenced increasingly through dilution by detrital clay and silt, resulting in lower reservoir potential and higher seal potential. Laterally, time-equivalent strata are more biosiliceous away from input points of terrigenous clay minerals into the basin.

Insights gained from constructing the sequence-stratigraphic framework were applied across the stratigraphic hierarchy from bed to sequence set, allowing integration of data from thin-section to seismic scale. Sequence-stratigraphic analysis was an important part of seismic inversion and rock-property mapping because it reveals genetically related rocks. This enables application of process-based models and incorporation of regional context and information about sedimentary provenance, paleogeography, and paleo-oceanography that are not discernible from seismic data alone.
12 Mowry Shale–Belle Fourche Shale, Bighorn Basin, Wyoming, USA—A Mesozoic Clastic-Biosiliceous Shelf System: A Prolific Source Rock with Associated Mudstone Reservoir Potential

Published: March 2024

The Cretaceous Mowry Shale and associated units in the Bighorn Basin of Wyoming, illustrate the expression of sequence-stratigraphic surfaces and units in a Mesozoic epeiric sea in a proximal to distal, detrital-to-biogenic–dominated shelf setting. Associated units include the Muddy Sandstone, Belle Fourche Shale, and Frontier Formation and are of Albian–Cenomanian age. The Mowry Shale is a highly siliceous mudstone, significantly enriched in marine organic matter that served as a prolific source rock across the Western Interior basin of the United States. It is also a source of bentonite as well as a mudstone reservoir.

Vertical and lateral variations of rock properties are predictable within a sequence-stratigraphic framework. The strata of the Mowry Shale and associated units record the interplay of intrabasin organic production (algal blooms) and associated surges in zooplankton population (mainly radiolaria) versus extrabasinal detrital siliciclastic input (a mixture of siliceous sand and clay minerals). Lowstand systems tracts are dominated by siliceous sandstone and minimal biogenic content because of poor primary production and dilution by extrabasinal detritus. The transgressive systems tract shows a marked change from a lower interval dominated by extrabasinal detrital argillaceous-siliceous mudstone to an upper interval dominated by intrabasinal biogenic siliceous and siliceous-carbonaceous mudstone. The intrabasinal biogenic siliceous and siliceous-carbonaceous mudstone continues into the lowermost interval of the highstand systems tract. Another distinct change, back to extrabasinal detrital argillaceous-siliceous mudstone to siliceous sandstone, marks the mid to upper highstand systems tract.

This chapter illustrates how the sequence-stratigraphic approach can be scaled practically to the data and time available for investigation and does not depend necessarily on large amounts of original proprietary work. This systematic approach helps make full and appropriate use of published observations to complete a stratigraphic framework. This chapter also illustrates the construction of a provisional sequence-stratigraphic framework based on the type and amount of data commonly available early in the investigation of a basin: outcrop sections, well logs, and some published analyses (similar to our example of the Kimmeridge Clay Formation in Bohacs et al. [2022d, Chapter 11 this Memoir]). Such a preliminary framework is useful to focus more detailed analyses on targeted intervals and rock properties, and to integrate information gained later by biostratigraphy, geochemistry, geomechanics, and petrography.
14 Green River Formation, Laney Member, Eocene, Wyoming, USA—A Balanced-Fill Lake System with Microbial Carbonate and Oil Shale, an Analog for Part of the South Atlantic Pre-Salt

Published: March 2024

The Green River Formation illustrates the expression of sequence-stratigraphic surfaces and units in lacustrine and alluvial strata. These settings are distinctly different from those of most of the mudstone units considered in this book. Our study shows how applying the sequence-stratigraphic method and approach from first principles in continental settings can provide insights into the accumulation of mudstones enriched in organic matter and biogenic material. These settings also have substantial hydrocarbon source, reservoir, and seal potential. Indeed, lacustrine settings host many of the largest oil discoveries of this century.

This setting offers an opportunity to examine the expression of parasequences, depositional sequences, and key surfaces in a setting that is significantly different from the more commonly studied marine settings. Although lakes may seem completely different from oceans, they have enough similarities with oceans that their differences tell us much about what is really essential about sequence stratigraphy—and what is an accident of the depositional setting. The sequence-stratigraphic approach of recognizing a hierarchy of rock packages bounded by various surfaces works very well in lake strata. In studying lacustrine strata, we recognize the same types of sequence-stratigraphic surfaces as in marine settings along with similar stratal stacking patterns. The expressions of parasequences and sequences differ between marine and lacustrine settings, however, because of significant differences among the dynamics and responses of these systems. Despite these differences, we see that the sequence-stratigraphic approach works well for lakes. Separate models, however, are needed for each of three lake-basin types to summarize the lacustrine sequence expression—just as shallow-marine carbonate sequences look different from shallow-marine siliciclastic sequences and require separate models. Contrasts among lake and marine systems make it inappropriate to directly apply one unmodified marine sequence-stratigraphic model to all lake systems. Indeed, one lacustrine model is not applicable to all lake-basin types.
Gendered debates? The use of gender-sensitive language in German televised debates, 1997–2022
Authors: Bast Jennifer , Maier Jürgen , Albert Georg , Schneider Jan Georg
Published: March 2024

Germany is a prime example of a country where the use of gender-sensitive language is the subject of public controversy and debate. This study provides a quantitative content analysis of all (N = 72) German televised debates aired on the federal and state level from 1997 until 2022 to explore the determinants of the use of gender-sensitive language by political candidates. We find that the use of gender-sensitive language has increased over time, but the effect is small and not robust. Party affiliation correlates with candidates’ linguistic behaviour, indicating that conservative candidates use less gender-sensitive language. Candidates’ gender and party affiliation, as well as parties’ socio-political positions, interact in predicting the use of gender-sensitive language. Candidates also change their use of gender-sensitive language from one debate to another. Compared to liberal/left-wing candidates, these changes are less likely to be associated with an increase in gender-sensitive language for conservative candidates.

Published: March 2024

Data extraction from optical networks has increased substantially with the evolution of monitoring and telemetry methods. Using data analysis and machine learning, this paper aims to derive insights from this data, contributing to the development of self-optimized optical networks. More particularly, it focuses on predicting the Kerr and amplified spontaneous emission dominance by examining the fluctuations in the signal-to-noise ratio due to polarization-dependent loss. Building on previous work, which used the SNR statistic as the input feature of machine learning, our primary goal is to enhance prediction precision while concurrently decreasing the computational model’s complexity. After refining the selection parameters of the input features, we observed a 70% reduction in the input feature length with respect to our previous work. The model reached a 98% accuracy rate, and it was able to successfully classify the regimes in a limited set of unseen experimental instances.
Dark solitons in liquid crystals with competing re-orientational and thermal nonlocal nonlinearities
Authors: Pu Shaozhi , Liang Ying , Ren Siqi , Du Mingxin , Zhang Meng
Published: March 2024

The properties of dark solitons in liquid crystals with competing nonlinearities are investigated by the model proposed by Jung. Under the condition of the rectangular response function, the relationship between the width of the dark soliton and the parameters of the medium is obtained by the variational method. It is found that the width of the dark solitons first decreases and then increases with the increment of the orientational nonlocality, the width of the soliton increases monotonously with the increase of the thermal nonlocality, and the width of the soliton decreases monotonously with the increase of the thermal nonlinearity coefficient. It is also found that the width of dark solitons is more sensitive to the orientational nonlocality than the other parameters. In addition, the width of the soliton increases monotonously with the grayness of the solitons. The analytical results are consistent with the numerical simulations that are obtained by the split-step Fourier algorithm.

Published: March 2024

A distributed optical fiber magnetic field sensor based on a polarization-sensitive optical frequency domain reflectometer (POFDR) is proposed. It extracts the accumulated Faraday rotation by combining the Stokes vectors and the backward Mueller matrices from the measured states of polarization (SOPs) and obtains the magnetic field component. This method avoids adjusting the input polarization during the magnetic field sensing process. It overcomes the drawback of the conventional POFDR scheme, which requires at least two sets of different input SOPs for each sensing. Finally, the aforementioned effectiveness has been experimentally verified by using a single-mode sensing fiber. The results show that the sensor has good repeatability and linearity. The measurement error of the magnetic field sensor is 19.4 mT. The measured magnetic field variations agree with the applied ones with similarities higher than 0.98.

Authors: Cui Anjing , Li Daojing , Wu Jiang , Gao Jinghan
Published: March 2024

According to the principle of synthetic aperture ladar, high-resolution imaging can be achieved if the relative motion exists between the target and the ladar. The imaging system has characteristics including a large field of view, narrow-band laser signals applied, and easy engineering implementation. The complex image reconstruction and the synthetic aperture laser imaging method for moving targets based on the spatial light modulator and the direct-detection detector array are proposed. The far-field simulations and the near-field experiments for the stop-and-go target and the continuous-moving target were carried out. It is verified that the complex image reconstruction method can equivalently realize coherent detection for the target and reflect its phase information corresponding to the laser wavelength. Multi-frame complex images reconstructed can be applied to the synthetic aperture laser imaging, which forms high-resolution images for moving targets under far/near-field conditions.
DaISy: diffuser-aided sub-THz imaging system
Authors: Wu Shao-Hsuan , Zhang Yiyao , Chen Ke , Yang Shang-Hua
Published: March 2024

Sub-terahertz (Sub-THz) waves possess exceptional attributes, capable of penetrating non-metallic and non-polarized materials while ensuring bio-safety. However, their practicality in imaging is marred by the emergence of troublesome speckle artifacts, primarily due to diffraction effects caused by wavelengths comparable to object dimensions. In addressing this limitation, we present the Diffuser-aided sub-THz Imaging System (DaISy), which utilizes a diffuser and a focusing lens to convert coherent waves into incoherent counterparts. The cornerstone of our progress lies in a coherence theory-based theoretical framework, pivotal for designing and validating the THz diffuser, and systematically evaluating speckle phenomena. Our experimental results utilizing DaISy reveal substantial improvements in imaging quality and nearly diffraction-limited spatial resolution. Moreover, we demonstrate a tangible application of DaISy in the scenario of security scanning, highlighting the versatile potential of sub-THz waves in miscellaneous fields.

Published: March 2024

The lensless camera with incoherent illumination has gained significant research interest for its thin and flexible structure. However, it faces challenges in resolving scenes with a wide depth of field (DoF) due to its depth-dependent point spread function (PSF). In this paper, we present a single-shot method for extending the DoF in Fresnel zone aperture (FZA) cameras at visible wavelengths through passive depth estimation. The improved ternary search method is utilized to determine the depth of targets rapidly by evaluating the sharpness of the back propagation reconstruction. Based on the depth estimation results, a set of reconstructed images focused on targets at varying depths are derived from the encoded image. After that, the DoF is extended through focus stacking. The experimental results demonstrate an 8-fold increase compared with the calibrated DoF at 130 mm depth. Moreover, our depth estimation method is five times faster than the traversal method, while maintaining the same level of accuracy. The proposed method facilitates the development of lensless imaging in practical applications such as photography, microscopy, and surveillance.
SC and OFDM hybrid coherent optical transmission scheme based on 1-bit bandpass delta-sigma modulation
Authors: Xie Tangyao , Xin Xiangjun , Fang Liye , Yan Hengxin , Pan Xiaolong , Li Xinying
Published: March 2024

High-order quadrature amplitude modulation (QAM) can effectively improve the capacity and spectral efficiency of coherent optical transmission systems. However, as the modulation order increases, the signal becomes less tolerant to noise and nonlinear effects during transmission, and the implementation cost also increases. We propose a single carrier (SC) and orthogonal frequency division multiplexing (OFDM) hybrid coherent optical transmission scheme based on a 1-bit bandpass (BP) delta-sigma modulation (DSM). The driving I-channel and Q-channel signals for the optical in-phase/quadrature (I/Q) modulator carry SC-modulated and OFDM-modulated transmitter data, respectively. Optical quadrature-phase-shift-keying (QPSK) modulation is realized by the 1-bit DSM quantizer and I/Q modulator, which can effectively suppress quantization noise and reduce the complexity of digital signal processing (DSP) and the performance requirements of optoelectronic devices. In addition, the hybrid transmission of SC and OFDM can balance the advantages of both to meet the variable channel conditions and complex application scenarios. High-fidelity transmission of SC 512QAM and OFDM 512QAM hybrid signals, in the form of a 60 Gbaud optical QPSK signal, over 60 km single-mode fiber-28 (SMF-28) is verified by offline experiments, and the bit error rates (BERs) of both SC 512QAM and OFDM 512QAM are below the hard-decision forward-error correction (HD-FEC) threshold of 3.8e-3.

Published: March 2024

Hyperreflective foci (HRFs) appear in optical coherence tomography (OCT) images of the retina and vitreous of patients with various ocular diseases. HRFs are hypothesized to be immune cells that appear in response to ischemia or tissue damage. To accurately identify HRFs and establish their clinical significance, it is necessary to replicate the detection of similar patterns in vivo in a small animal model. We combined visible-light OCT with temporal speckle averaging (TSA) to visualize and track vitreal HRFs (VHRFs) densities for three days after an optic nerve crush (ONC) injury. Resulting vis-OCT images revealed that VHRF density significantly increased approximately 10-fold at 12 h after ONC and returned to baseline three days after ONC. Additional immunohistochemistry results confirmed these VHRFs as inflammatory cells induced from optic nerve damage.

Published: March 2024

Flexible optoelectronic platforms, which integrate optoelectronic devices on a flexible substrate, are promising in more complex working environments benefiting from the mechanical flexibility. Herein, for the first time to the best of our knowledge, a flexible GaN-based vertical cavity surface-emitting laser (VCSEL) in the ultraviolet A (UVA) range was demonstrated by using a thin-film transfer process based on laser lift-off (LLO) and spin-coating of a flexible substrate. The lasing wavelength is 376.5 nm with a linewidth of 0.6 nm and threshold energy of 98.4 nJ/pulse, corresponding to a threshold energy density of 13.9 mJ/cm2. The flexible substrate in this study is directly formed by spin-coating of photosensitive epoxy resin, which is much simplified and cost-effective, and a 2-in. wafer scale GaN-based membrane can be successfully transferred to a flexible substrate through this method. Such flexible UVA VCSELs are promising for the development of next-generation flexible and wearable technologies.
Optimized LNS-FAID of LDPC codes: a hybrid precision decoding approach for 50G-PON
Authors: Lyu Yanchen , Jiang Ming , Zhu Mingyang , Zhong Xinyu , Zhao Chunming
Published: March 2024

Efficient error correction in high-speed communication networks, such as the 50G passive optical network (50G-PON), is paramount. This Letter focuses on optimizing a layered non-surjective finite alphabet iterative decoder (LNS-FAID) for 50G-PON, with an emphasis on high-throughput and low-power consumption. We propose using a distinct lookup table (LUT) for each iteration to enhance decoding performance and lower error floors. Additionally, we improve the 2-bit LNS-FAID architecture by adding operational states and a sign backtracking (SBT) strategy. This paper also introduces a hybrid precision model that merges 3-bit and 2-bit LNS-FAIDs, which balances error correction with computational efficiency. Our simulation results show that these approaches significantly improve the performance of the LDPC code in 50G-PON.
Dead-zone-free atomic magnetometer based on hybrid Poincaré beams
Authors: Tian Ke , Ding Weifeng , Wang Zhaoying
Published: March 2024

In this paper, we present the experiment and the theory scheme of light-atom interaction in atomic magnetometers by using a hybrid Poincaré beam (HPB) to solve an annoying problem, named “dead zone.” This kind of magnetometer can be sensitive to arbitrary directions of external magnetic fields. The HPB has a complex polarization distribution, consisting of a vector radially polarized beam and a scalar circularly polarized beam in our experiment. These two kinds of beams have different directions of dead zones of external magnetic fields; thereby, the atomic magnetometer with an HPB can avoid the non-signal area when the direction of the external magnetic field is in the plane perpendicular to the light polarization plane. Furthermore, the optical magnetic resonance (OMR) signal using an HPB still has no dead zones even when the direction of the external magnetic field is in the plane parallel to the polarization plane in our scheme. Our work has the potential to simplify and optimize dead-zone-free atomic magnetometers.
Pro-cycling team cyclist assignment for an upcoming race

Published: March 2024

Professional bicycle racing is a popular sport that has attracted significant attention in recent years. The evolution and ubiquitous use of sensors allow cyclists to measure many metrics including power, heart rate, speed, cadence, and more in training and racing. In this paper we explore for the first time assignment of a subset of a team’s cyclists to an upcoming race. We introduce RaceFit, a model that recommends, based on recent workouts and past assignments, cyclists for participation in an upcoming race. RaceFit consists of binary classifiers that are trained on pairs of a cyclist and a race, described by their relevant properties (features) such as the cyclist’s demographic properties, as well as features extracted from his workout data from recent weeks; as well additional properties of the race, such as its distance, elevation gain, and more. Two main approaches are introduced in recommending on each stage in a race and aggregate from it to the race, or on the entire race. The model training is based on binary label which represent participation of cyclist in a race (or in a stage) in past events. We evaluated RaceFit rigorously on a large dataset of three pro-cycling teams’ cyclists and race data achieving up to 80% precision@i. The first experiment had shown that using TP or STRAVA data performs the same. Then the best-performing parameters of the framework are using 5 weeks time window, imputation was effective, and the CatBoost classifier performed best. However, the model with any of the parameters performed always better than the baselines, in which the cyclists are assigned based on their popularity in historical data. Additionally, we present the top-ranked predictive features.
Efficacy of Wolbachia-based mosquito control: Predictions of a spatially discrete mathematical model
Authors: Dye David , Cain John W.
Published: March 2024

Wolbachia is an endosymbiont bacterium present in many insect species. When Wolbachia-carrying male Aedes aegypti mosquitoes mate with non-carrier females, their embryos are not viable due to cytoplasmic incompatibility. This phenomenon has been exploited successfully for the purpose of controlling mosquito populations and the spread of mosquito-borne illnesses: Wolbachia carriers are bred and released into the environment. Because Wolbachia is not harmful to humans, this method of mosquito control is regarded as a safer alternative to pesticide spraying. In this article, we introduce a mathematical framework for exploring (i) whether a one-time release of Wolbachia carriers can elicit a sustained presence of carriers near the release site, and (ii) the extent to which spatial propagation of carriers may allow them to establish fixation in other territories. While some prior studies have formulated mosquito dispersal models using advection-reaction-diffusion PDEs, the predictive power of such models requires careful ecological mapping: advection and diffusion coefficients exhibit significant spatial dependence due to heterogeneity of resources and topography. Here, we adopt a courser-grained view, regarding the environment as a network of discrete, diffusively-coupled “habitats”—distinct zones of high mosquito density such as stagnant ponds. We extend two previously published single-habitat mosquito models to multiple habitats, and calculate rates of migration between pairs of habitats using dispersal kernels. Our primary results are quantitative estimates regarding how the success of carrier fixation in one or more habitats is determined by: the number of carriers released, sizes of habitats, distances between habitats, and the rate of migration between habitats. Besides yielding sensible and potentially useful predictions regarding the success of Wolbachia-based control, our framework applies to other approaches (e.g., gene drives) and contexts beyond the realm of insect pest control.

Published: March 2024

Background

Quad bikes are popular recreational, four-wheeled bikes in the Middle East. Injury prevention programs targeting quad bike crashes in the United Arab Emirates (UAE) need evidence about the risk factors and behaviours associated with these crashes in the target population. This is a protocol for a study aiming to investigate quad bike rider behaviours and to assess the risk factors associated with related injuries in the UAE.

Methods

This is a cross-sectional observational study aiming to describe a seasonal sport in a desert environment. With an estimated sample size of 451, the survey will follow a three-stage, location-based sampling strategy using the line-transect method. A sampling frame of desert locations with high injury incidences was developed, using Dubai ambulance injury records. Further expansion of the sampling frame was participatory, involving police, enthusiasts, emergency responders and gas station employees. The data collection will be limited to the winter months in fifteen high-injury desert locations across three major Emirates in the UAE. Trained researchers will observe the riders directly in the desert to note their riding habits, followed by a researcher-administered interview on riding and injury history. The interviews will be administered in Arabic and English using Qualtrics software on handheld tablets with offline and online entry mode. In addition, paper-based entry with the same format will be used as a contingency in busy quad bike locations.

Conclusion

The objective of this study protocol is to develop a comprehensive survey that will furnish substantial evidence for the formulation of effective injury prevention strategies. To enhance the credibility of the recorded riding behaviors, field observations will be employed. The uniqueness of this study lies in its innovative sampling strategy, custom-tailored to accommodate the highly mobile and transient population of desert bikers in the UAE.
Impact of hearing impairment on the mental status of the adults and older adults in Jordanian society
Authors: Alqudah Safa , Zuriekat Margaret , Shatarah Aya
Published: March 2024

Background

Hearing loss is a common disorder, affecting both children and adults worldwide. Individuals with hearing loss suffer from mental health problems that affect their quality of life.

Objective

This study aimed to investigate the social and emotional consequences of hearing loss in a Jordanian population using Arabic versions of the Hearing Handicap Inventory for Adults (HHIA) and the Hearing Handicap Inventory for the Elderly (HHIE).

Methods

This study included 300 Jordanian participants aged 18–90 years with hearing loss. Each participant underwent a complete audiological evaluation before answering the questionnaires.

Results

The median overall scores of the HHIA and HHIE groups were 39 and 65, respectively. Both HHIA (Cronbach’s alpha = 0.79, p < 0.001) and HHIE (Cronbach’s alpha = 0.78, p < 0.001) were significantly associated with the social, emotional, and overall scores. Compared to the adult group, the median emotional and social scores of the older adults group were significantly higher than the adults group (Z = -4.721, p = 0.001), using the Mann-Whitney test.

Conclusion

The present research revealed that psychological disabilities associated with hearing loss in the adult Jordanian population are more frequent and severe than in other nations. This may be attributed to the lack of awareness of the mental consequences of hearing loss among Jordanian healthcare providers and the public.

Published: March 2024

To investigate the influence of the pore structure characteristics of aeolian sand concrete on the mechanical properties, macroscopic mechanical tests of aeolian sand concrete were performed under different conditions, and the influences of the water-cement ratio, sand ratio, and aeolian sand replacement rate on the compressive strength were analysed. The internal microscopic pore structure was characterised using scanning electron microscopy and nuclear magnetic resonance. The impact of pore structure parameters on compressive strength was determined by the grey relational entropy, and a pore structure-strength model was established.

Gender and social inclusion integration is now established as an essential dimension of climate change resilience. It is the option to achieve inclusive, equitable and just climate change resilience configurations. A main lever for significant progress in the integration of gender and social inclusion in climate change resilience policies is efficient and participatory scientific frameworks for specific vulnerable social groups identification, the development of climate change specific impacts, vulnerabilities and resilience solutions families for gender and social inclusion. These scientific frameworks should also be multi-dimensional and take into account climate change indirect impacts.

The purpose of this article is to describe the Badolo ClimGender scientific framework, an innovative scientific framework for gender and social inclusion integration in climate change resilience. The singularities, relevance and efficiency of this scientific framework result from its approach, methodological tools, corpuses of information and solutions and integration scheme.

The main results of this article are plans for gender and social inclusion integration in sectoral climate change resilience policies, implementing the concepts of specific vulnerable social groups, specific climate change impacts, vulnerabilities, resilience solutions and inclusive resilience configurations and markers. They include sequential gender and social inclusion integration actions to achieve successive partial inclusive resilience configurations.

The results of this article suggest a climate change inclusive resilience governance, based more on the criteria of relevance, efficiency and sustainability. Its levers are the engagement, mobilization, participation and contribution of social groups specifically affected by climate change.

The use of drones to evaluate crops has become increasingly common. Among these uses, the drone helps in the cultivation of cotton a crop that is highly prone to intense attacks by pests and diseases. This study aimed to evaluate the use of drones in evaluating trials in cotton cultivation in the Southwest of Goiás, Brazil. A Phantom 4 Pro drone was used to carry out the mapping and WebODM was used to carry out photogrammetry and obtain the ExG vegetation index. ExG proved to be efficient in detecting differences between blocks. The use of drones provided a series of benefits in the assessment process in cotton cultivation. The ability to fly over the area quickly and accurately allowed detailed, and punctual images to be obtained which was essential for monitoring plant health and identifying problem areas such as pest or disease infestations.

Published: March 2024

Some vascular endothelial growth factor receptor-1 (VEGFR-1) inhibitors drugs have been used to cancer cells; however, their interaction with VEGFR-1 is very confusing. The objective of this research was to evaluate the possible interaction of eight steroid derivatives with VEGFR-1 surface using 3hgn protein, cabozantinib, pazopanib, regorafenib, and sorafenib as theoretical tools in DockingServer program. The results showed some differences in the interaction of the steroid derivatives (1-8) with the 3hng protein surface such as i) differences in the number of amino acids; ii) different position of some amino acids compared to cabozantinib, pazopanib, regorafenib, and sorafenib. Besides, the inhibition constant (Ki) for steroid derivatives 1, 3, 6 and 8 was lower compared to cabozantinib and sorafenib drugs. In addition, other data display that Ki for steroid analogs 1, 3, 4, 6, 7 and 8 was lower compared with pazopanib and regorafenib. In conclusion, all these data suggest that steroid derivatives 1, 3, 4, 6, 7 and 8 could act as VEGFR-1 inhibitors and this phenomenon could be translated as good compounds to treat cancer cells.

Introducción/objetivo: en este estudio se comparó la prevalencia de victimización por ciberviolencia en el noviazgo (CVN) por edad y sexo, en un grupo de adolescentes y adultos jóvenes colombianos y se examinó si la frecuencia de conductas de CVN sufridas se relacionaba con el número de intentos de suicidio y escapadas de la casa, la calidad de las relaciones con pares, adultos y familiares y el rendimiento académico. Método: participaron 1971 adolescentes y adultos jóvenes de 13 a 26 años de edad. Se utilizó el CDAQ y un cuestionario de variables psicológicas. Resultados: el 81.3 % de los participantes informó haber sufrido al menos una conducta de CVN; este porcentaje es significativamente mayor entre los adolescentes que entre los adultos jóvenes. Hubo diferencias estadísticas altamente significativas por sexo en las conductas de CVN sufridas; los hombres informaron con mayor frecuencia ser víctima de agresiones. Todas las variables correlacionaron de manera significativa con la frecuencia de conductas de CVN sufridas. Los participantes que sufrieron al menos una conducta de CVN informaron de un incremento significativo en el número de escapadas de la casa y una menor calidad de las relaciones con adultos, pares y familiares. Conclusiones: estos resultados sugieren que la CVN afecta más a los adolescentes que a los adultos jóvenes, y que las víctimas podrían presentar diversas dificultades en su entorno familiar y social.
Nicolás Dip. Movimientos estudiantiles en América Latina. Interrogantes para su historia, presente y futuro
Authors: Hidalgo Carlos Celi
Published: March 2024

Con una escritura clara y contundente, el libro de Dip aborda más de cien años de historia de los movimientos estudiantiles en América Latina. El texto se organiza a partir de una batería de preguntas que se despliegan a lo largo de todo el documento y que indagan alrededor del ¿Qué son?, ¿Cuál es su importancia?, ¿Qué fue la Reforma del 18?, ¿Existió un 68 latinoamericano?, ¿Están vivos los Movimientos Estudiantiles?, ¿Lugares comunes?, ¿Todo concluye al fin? Las preguntas planteadas por el escrito son sencillas pero imprescindibles. Este se convierte en un vademécum del quehacer de los movimientos estudiantiles en la región, despeja una serie de dudas que normalmente son las que se plantean quienes se acercan a leer alrededor del tema. En un vuelo rasante a lo largo de los más de cien años de historia de los movimientos en el continente, el texto de Dip también tiene bastante de documento cartográfico que sirve para ubicarte a lo largo del tiempo y en las diferentes geografías acerca del devenir de los movimientos estudiantiles. Aunque no por ello deja de abordar temáticas complejas, las mismas se convierten en la pluma de Dip en un producto de sencilla deglución debido al ejercicio intelectual del autor que se esfuerza por entregar un instrumento que facilite la divulgación y conocimiento acerca del tema.
Regatones, mercachifles o ambulantes informales de Lima colonial
Authors: Rivasplata Varillas Paula Ermila
Published: March 2024

Este artículo trata del surgimiento de los ambulantes informales en Lima colonial y la gestión de las autoridades para erradicarlos. En la capital del virreinato del Perú, la regatonería fue ejercida en mayor medida por las mujeres que por los hombres y era bastante perseguida y denunciada por las autoridades por la venta informal al menudeo de productos de primera necesidad, comprados al por mayor. La informalidad fue la constante en las calles limeñas y las autoridades trataron, incluso, de formalizar la regatonería con intentos fallidos, para obtener mayores ganancias por parte de los cajoneros, un tipo de vendedor formal, con beneplácito del cabildo.
Revisitando la Participación en los inicios de la IAP¿Qué era Investigar para los campesinos de la Costa Caribe colombiana?
Authors: Rappaport Joanne
Published: March 2024

Las reflexiones sobre la investigación participativa y colaborativa suelen dejar de prestar atención al hecho de que, para los investigadores comunitarios, la investigación de sus propias realidades suele adoptar formas muy diferentes a las de los académicos. Pueden utilizar métodos que son explícitamente intuitivos y pueden apartarse de enfoques que implican la recopilación y sistematización rigurosa de datos. Este artículo explora lo que la investigación pudo haber significado para los campesinos caribeños de principios de la década de 1970 con quienes el sociólogo colombiano Orlando Fals Borda desarrollo? su enfoque de lo que hoy se llama investigacionaciòn participativa. En particular, se centra en las notas de campo de Alfonso Salgado Martínez, líder de la Asociación Nacional de Usuarios Campesinos-Lìnea Sincelejo (ANUC, Asociación Nacional de Usuarios Campesinos-Linea Sincelejo), yuxtaponiéndolas a su trabajo publicado, ambos leídos en comparación a las notas y escritos del propio Fals Borda
Abordaje quirurgico mediante la técnica vista y uso de miniimplantes para tracción ortodóntica: reporte de casos
Authors: Feria Julian Angel , Tovío Martínez Eilien , Urbano Del Valle Samuel Enrique
Published: March 2024

Los caninos se pueden encontrar en situación heterotópica; fosas nasales, seno maxilar, sínfisis mentoniana, o ectópicamente cerca de su asiento normal, pero en diferentes posiciones. Lo más frecuente es que presente su eje oblicuo hacia mesial, generalmente en palatino o vestibular en el caso de los inferiores, y relativamente frecuente bilateral. La sintomatología es nula en la inclusión y el diente se diagnostica por otros hechos o existe apariencia clínica en el caso de enclavamiento. El abordaje Ortoquirúrgico de los caninos retenidos ha evolucionado en las últimas décadas, con la inclusión de los aditamentos de anclaje absoluto (miniimplantes), los planes de tratamiento ortoquirúrgico se han visto en la necesidad de modificar las técnicas quirúrgicas, el objetivo es llevar a cabo la tracción de caninos con la técnica VISTA, y posicionarlo adecuadamente en la arcada. Anteriormente se llevaban a cabo diferentes técnicas, a nivel vestibular se realizaban colgajos con reposición apical o técnicas poco recomendables como la fenestración mucosa pues ésta podría producir problemas periodontales, por otra parte, a nivel palatino se realizaba la descubierta de los caninos incluidos mediante un colgajo mucoperióstico (técnica de ventana quirúrgica), en el que se realiza una alveolotomía conductora. Por todo ello, ha de tenerse en cuenta que la aparatología fija ortodóntica proporciona una alternativa que evita la extracción de órganos dentales retenidos, a través de técnicas quirúrgicas mínimamente invasivas, que permiten mantener los caninos en la arcada dental y por tanto a la armonía de las arcadas dentales.
How to Crack the Sugar Code
Authors: Gabius H.-J.
Published: March 2024

The known ubiquitous presence of glycans fulfils an essential prerequisite for fundamental roles in cell sociology. Since carbohydrates are chemically predestined to form biochemical messages of a maximum of structural diversity in a minimum of space, coding of biological information by sugars is the reason for the broad occurrence of cellular glycoconjugates. Their glycans originate from sophisticated enzymatic assembly and dynamically adaptable remodelling. These signals are read and translated into effects by receptors (lectins). The functional pairing between lectins and their counterreceptor(s) is highly specific, often orchestrated by intimate co-regulation of the receptor, the cognate glycan and the bioactive scaffold (e.g., an integrin). Bottom-up approaches, teaming up synthetic and supramolecular chemistry to prepare fully programmable nanoparticles as binding partners with systematic network analysis of lectins and rational design of variants, enable us to delineate the rules of the sugar code.
Surrogacy and dystopian positionality: narrative reproduction between speculative fiction and chick lit
Authors: Wurr Julia
Published: March 2024

When it comes to Anglophone surrogate fictions, it seems that one reader’s dystopia is another writer’s chick lit: whereas widely received fictional narratives about surrogacy which are set in a future North America, such as The Handmaid’s Tale and The Farm, are mostly read as dystopian or speculative fiction, the small corpus of novels which negotiate commercial surrogacy in India (Origins of Love, The House of Hidden Mothers and A House for Happy Mothers) all contain chick-lit elements. As this constellation of genres might create the impression that exploitative forms of surrogacy do not exist yet, this article brings together postcolonial and ethnographic scholarship on surrogacy with research from gender and queer studies in order to explore the wider socio-political implications of these generic complexities. Arguing that more work is needed to conceptualise dystopian positionality, the article first shows that speculative and dystopian texts about surrogacy often invite Western-centric interpretations in which the dystopian element is mostly configured in temporal terms while aspects of space and positionality tend to be neglected or universalised. Further unfolding the generic complexities of surrogate fictions, the article then explores the extent to which the chick-lit mode in the texts on Indian surrogacy consolidates biocapitalist consumer market ideologies. In a last step, the article discusses the interconnections between generic conventions and hetero- and bionormative teleologies, and it reflects on the problems which might arise when attempts to deconstruct heteronormative assumptions about reproduction do not simultaneously also question the – often stratifying – implications of bionormativity.
