On the persistence of SVO: the case of Modern Eastern Armenian
Authors: Samvelian Pollet , Faghiri Pegah , Khurshudyan Victoria 
Published: March 2023

AbstractThis study addresses the issue of unmarked word order in Modern Eastern Armenian (MEA), typologically considered a flexible (S)OV language due to its being strongly left-branching as well as the syntactic properties of its VP (focus, bare objects, low adverbs). However, Armenian grammars generally consider (S)VO to be the canonical order. We have conducted a corpus study and two sentence production experiments to tackle this controversy. These studies show that the placement of direct objects (DOs) is mainly triggered by definiteness. While definite DOs are overwhelmingly postverbal, indefinite DOs display a strong preference for preverbal placement. This implies a “typological discrepancy”: although MEA is a strongly left-branching language, the unmarked placement of definite DOs is postverbal. We account for this “discrepancy” based on areal, historical and cognitive factors. Contact with OV languages has resulted in a consistent shift from right to left-branching in Armenian, whereas word order at the clausal level has resisted the shift because MEA makes optimal use of each order in accordance with their cognitive advantages. The evolution of word order in MEA is an illustration of the universal crosslinguistic bias toward SVO.

Abstract
The concerning issue regarding petrochemical plastic wastes had prompted scientists and researchers to develop biodegradable plastic in effort to tackle environmental pollution. Alternative bioresources such as poly (lactic acid), sugar palm starch and nanocellulose fibre were utilized in producing cheap, biodegradable and sustainable plastic with satisfactory mechanical properties for food packaging application. In this study, sugar palm crystalline nanocellulose (SPCNC) was priorly dispersed in thermoplastic sugar palm starch (TPS) before melt blended with poly (lactic acid) (PLA) and later compress moulded into a sheet form. Initial biodegradation test of PLA100 and all PLA/TPS blends bionanocomposite samples indicated that PLA60TPS40 has the least variation in weight loss due to the good miscibility between TPS and PLA promoting the reinforcement of SPCNC. Greater weight losses in seawater (17.54%), river water (18.97%) and sewer water (22.27%) result in greater mechanical degradation as observed at the reduction of tensile strength from 12.11 MPa to 2.72 MPa in seawater, 1.48 MPa in river water and 0.40 MPa in sewer water. Similarly, higher weight losses in seawater (22.16%), river water (21.6%) and sewer water (23.09%) correlated with the reduction of flexural strength from 18.37 MPa to 3.5 MPa in seawater, 3.83 MPa in river water and 3.6 MPa in sewer water. The scanning electron microscope (SEM) images of tensile fracture morphology demonstrated clear porous structure due to the removal of starch particles by microbial activity. The homogenous structure of PLA60TPS40 had a steady and consistent degradation, which wholly diminished the interfacial adhesion that led to mechanical properties losses. The mechanical strength reduction clarified that the biodegradation rate within the media used might be able to resolve the excessive non-biodegradable plastic waste in open waters.
A Halpern-type algorithm for a common solution of nonlinear problems in Banach spaces

Published: March 2023

Abstract
In this article, we propose a Halpern-type subgradient extragradient algorithm for solving a common element of the set of solutions of variational inequality problems for continuous monotone mappings and the set of f-fixed points of continuous f-pseudocontractive mappings in reflexive real Banach spaces. In addition, we prove a strong convergence theorem for the sequence generated by the algorithm. As a consequence, we obtain a scheme that converges strongly to a common f-fixed point of continuous f-pseudocontractive mappings and a scheme that converges strongly to a common zero of continuous monotone mappings in Banach spaces. Furthermore, we provide a numerical example to illustrate the implementability of our algorithm.

Published: March 2023

AbstractFor shade‐intolerant plants, changes in light quality through competition from neighbors trigger shade avoidance syndrome (SAS): a series of morphological and physiological adaptations that are ultimately detrimental to plant health and crop yield. Phytochrome‐interacting factor 7 (PIF7) is a major transcriptional regulator of SAS in Arabidopsis; however, how it regulates gene expression is not fully understood. Here, we show that PIF7 directly interacts with the histone chaperone anti‐silencing factor 1 (ASF1). The ASF1‐deprived asf1ab mutant showed defective shade‐induced hypocotyl elongation. Histone regulator homolog A (HIRA), which mediates deposition of the H3.3 variant into chromatin, is also involved in SAS. RNA/ChIP‐sequencing analyses identified the role of ASF1 in the direct regulation of a subset of PIF7 target genes. Furthermore, shade‐elicited gene activation is accompanied by H3.3 enrichment, which is mediated by the PIF7‐ASF1‐HIRA regulatory module. Collectively, our data reveal that PIF7 recruits ASF1‐HIRA to increase H3.3 incorporation into chromatin to promote gene transcription, thus enabling plants to effectively respond to environmental shade.

AbstractIntracellular organization is largely mediated by actin turnover. Cellular actin networks continuously assemble and disassemble, while maintaining their overall appearance. This behavior, called “dynamic steady state,” allows cells to sense and adapt to their environment. However, how structural stability can be maintained during the constant turnover of a limited actin monomer pool is poorly understood. To answer this question, we developed an experimental system where polystyrene beads are propelled by an actin comet in a microwell containing a limited amount of components. We used the speed and the size of the actin comet tails to evaluate the system's monomer consumption and its lifetime. We established the relative contribution of actin assembly, disassembly, and recycling for a bead movement over tens of hours. Recycling mediated by cyclase‐associated protein (CAP) is the key step in allowing the reuse of monomers for multiple assembly cycles. ATP supply and protein aging are also factors that limit the lifetime of actin turnover. This work reveals the balancing mechanism for long‐term network assembly with a limited amount of building blocks.
A statistics-based review on island detection methods in microgrids: Overall investigation and state-of-the-art

Published: March 2023

AbstractIn this paper, a comprehensive statistics-based review of islanding detection methods (IDMs) in microgrids (MGs) is presented. Islanding detection is the situation of isolating the MG from the main grid whether programmed as a result of load managing purposes or un-programmed due to the occurrence of faults. Islanding detection is a vital issue in MG's analyses due to the prevention of subsequent protection problems in the power system. In other words, when the MG's operation mode changes, the current passing through the protective devices changes subsequently and the protection system should be able to adapt the new settings to the protective devices. So, IDMs are vital for electrical engineers to overcome the abovementioned protection issue. This review paper surveys the existing literature in IDMs by concentration on total publications, type of publications (journal, conference paper, or book), five authors with the highest number of publications (including the affiliations), and five most published sources. Also, the five most cited publications and state-of-the-art IDMs are investigated in detail, utilizing some known and novel categorizations. This paper will be useful for the MG's researchers to know the most desirable IDMs, especially in recent years, and provides an insightful overview for future studies.
“Because more trust now”: The Role of Peer Observation of Teaching in Building a Faculty Community of Practice
Authors: Deraney Philline 
Published: March 2023

As the main facilitators of teaching and learning, faculty developers’ views as individuals and as members of their academic communities are essential to higher education research. Yet, developers’ perceptions of their own growth and learning as practitioners are underrepresented in the extant literature. This qualitative study explored perceptions of a peer observation of teaching (PoT) program and its role in building a community of practice (CoP) amongst a nine-member team of faculty developers in a large university in Saudi Arabia. Participant data were collected through semi-structured interviews after two years of the program. A thematic content analysis of interview responses revealed four themes: 1) authentic collegiality and mutual communication improved through the shared experiences, which provided a foundation for the CoP; 2) participants’ perceptions of PoT shifted from an evaluative experience to a developmental one with noticeable challenges; 3) teaching and learning strategies and practices were enhanced from the observation experiences; and, 4) PoT contributed to building community through shared practice and/or sense of belonging. Implications of this study support explicit discussions about the foundation and underlying values of proposed PoT and related programs; a balanced, outcome-oriented yet still developmental program with follow-up opportunities; and, learner-centered and sustainable development that empowers a bilateral role and identity as both academician and faculty developer.

The intensive use of land has accelerated the loss of soil quality, a process that can be avoided by adopting conservationist production systems, such as the Integrated Crop-Livestock-Forest (CLFI system). It is noteworthy that in the Southwest of the State of Maranhão a substantial portion of soils in rural properties are degraded and in distinct stages of erosion, since they have been exploited for decades with non-properly managed pastures. Therefore, the objective of this work was to emphasize the importance of physical and chemical changes in the soil of pastures under crop-livestock-forest integration in general and in the Amazon region of state of Maranhão, Brazil. Therefore, a literature review was conducted through a search for studies in the Google Scholar database, which encompasses multiple other databases, such as Scielo, Elsevier, Scopus, Capes, and others. In face of the conditions of degradation in pastures throughout the state of Maranhão and the broad distribution of native forests such as Babassu forests, the use of technology from CLFI systems could allow for their recovery and sustainable status by means of economically and ecologically feasible productivity. Research on this field is therefore necessary to highlight short- and long-term efficiencies regarding carbon sequestration and quality of organic matter on the soil.

Published: March 2023

Un suivi des écoulements de résine sur troncs de cèdre associés à des nécroses cambiales a été réalisé entre 1992 et 2017 dans un dispositif sylvicole. Le taux d'arbres atteints a progressivement augmenté jusqu'à 50 % en 2015 avec une différence marquée entre traitements sylvicoles en 2004 (densité et hauteur d'élagage et interaction). En 2017, une analyse sur 84 arbres a montré que les nécroses se développent de préférence à la base du houppier vivant, à un âge cambial de 21-22 ans. Les nécroses et canaux résinifères apparaissent les années plutôt humides, notamment 2008. Les nécroses cicatrisent pour la plupart en 2-3 ans. L'intervention d'un champignon est suspectée.
Messages clés :• Des écoulements de résine associés à des nécroses cambiales sont signalés sur Cèdre.• Dans un dispositif expérimental sylvicole, les arbres à houppier développé (éclaircie forte, sans élagage) sont transitoirement plus touchés.• Les symptômes apparaissent préférentiellement à la base du houppier vivant (âge cambial de 21-22 ans) et plutôt les années humides.• On suspecte l'intervention d'un champignon.

L’étude menée sur 230 placettes temporaires de Pin d’Alep (Pinus halepensis Mill.) dans l’Aurès (Algérie) a pour objectif de construire deux tables de production pour deux itinéraires sylvicoles différents. Quatre classes de fertilité ont été définies avec des hauteurs dominantes à 70 ans de 19,50 m, 16,50 m, 13,50 m et 10,50 m, respectivement. Les effets de l’itinéraire sylvicole ne changent pas la production totale de bois en volume mais modifient la répartition des catégories de diamètre avec une proportion de gros bois de plus en plus élevée, ce qui permet une meilleure valorisation économique des peuplements.
Messages clés :• Deux tables de production ont été construites pour le Pin d’Alep en Algérie.• Ces tables intègrent deux itinéraires sylvicoles.• Selon l’itinéraire choisi, la valorisation économique est différente.
Optimizing Reservoir Pressure Management with Relief Wells During CO2 Storage in Finite Aquifers
Authors: Al Zayer Hassan A. , Saeed Muhammad S. 
Published: March 2023

Abstract
Storing CO2 in deep saline aquifers is a viable technology to manage carbon emissions. However, in finite aquifers, reservoir pressure builds up quickly which can reduce injectivity and limit the ultimate storable quantities of CO2. Therefore, the purpose of this work is to investigate the optimum design for reservoir pressure-management wells during carbon dioxide (CO2) storage in finite aquifers using a numerical simulation method.
In this paper, a synthetic aquifer model was used to investigate the optimal well placement and geometry, and well spacing to maximize CO2 storable quantities with a less total number of wells. Furthermore, the main target is to maximize the pore volume utilization and target injection rate per well without exceeding the reservoir fracture limit. A fit-for-purpose 3D reservoir simulation model used in this study was built to allow robust and accurate large-scale numerical simulation studies related to CO2 sequestration and storage using synthetic data.
Multiple CO2 gas injectors were placed at the crest of the structure to utilize most of the available pore volume and maximize the injection rate. Various pressure management schemes were modeled and compared to find out the optimal design which can provide maximum injection rate and ultimate storage capacity. The results showed that well placement depth and the number of active relief wells both are playing a major role in maximizing the ultimate storage efficiency. Since reservoir heterogeneity and anisotropy can significantly affect the relief wells’ design, streamlines tracing can be very helpful to optimize the well spacing and orientation. After 80 years of injection, the simulation sensitivity study showed a significant difference (10-20% of CO2 storage efficiency) between the different pressure management schemes. In conclusion, relief wells are often needed to manage reservoir pressure build-up during CO2 storage in finite aquifers and their design is vital in maximizing the ultimate CO2 storage capacity.
The outcome of this study is providing a useful guideline to optimize the field development plans and maximize the CO2 storage capacity in finite aquifers.

Published: March 2023

Abstract
Crushed soft coal seams have the features of low mechanical strength and broken coal structure. Fracturing directly in broken soft coal seams, short and coarse fractures are formed and a large amount of coal powder is produced. In this study, horizontal well indirect fracturing technology in the gangue of crushed soft coal seams was proposed to improve the coalbed methane (CBM) development effect.
Based on the No. 5 coal seam in the Daning-Jixian block of the Ordos Basin in China, the fracability of the gangue and coal seam were evaluated by logging interpretation, rock mechanical tests and immersion experiments. The technological process of horizontal well staged fracturing in the gangue of crushed soft coal seams was constructed by field test. A corresponding hydraulic fracturing physical simulation experiment was performed, and fracture propagation behaviors were investigated.
The results show that compared with crushed soft coal seams, gangue has better brittleness and fracability. Horizontal well indirect fracturing in gangue can well stimulate upper and lower coal seams, significantly decrease the fracturing pressure and fracture extension pressure, and reduce the production of coal power. The desirable crack extension and considerably enhanced production effect demonstrated the remarkable engineering feasibility of this technology. The suitable thickness is 0.5~1 m for mudstone gangue, whereas a thickness of 2~3 m is appropriate for interbedded sandstone and mudstone gangue. The stage spacing should be larger than 80 m, and the cluster spacing should be greater than 24 m to avoid the stress shadow effect. Hydraulic fractures initiated from the gangue of coal seams, first spread vertically in the gangue layer and extend rapidly along the interfaces between the coal seams and gangue, then penetrated the lithologic interface and expanded into the coal seams. The upper and lower coal seams were torn open, and 3D complex fractures were formed in the coal seams, creating flow channels for CBM into the horizontal wellbore.
This research presents a novel technical idea for the CBM extraction of crushed soft coal seams. The findings can offer guidance for the optimal design of horizontal well indirect fracturing in the gangue of crushed soft coal seams.

Abstract
Automatic under suspended load detection system is a term for an image processing method which is used to identify compliance and safety aspect of crane or lifting & rigging operations in drilling & completion activities especially under suspended load for line of fire prevention which possibly leads to a serious incident and fatality. According to company data statistics, approximately 30% of safety findings are contributed by lifting & rigging operations. As a state-owned company that operates one of the largest fields in Indonesia with an extensive drilling and well intervention programs, Pertamina Hulu Rokan (PHR) commits to protect the safety of their people by reducing lifting & rigging operations safety findings and improving its monitoring process. The company has taken the initiative to explore any digital alternatives that can be applied such as utilization of computer vision and artificial intelligence in online Closed-Circuit Television (CCTV) units to enable prevention of under suspended load case in drilling & completion operations by using deep learning algorithm such as Yolov4 and/or Faster R-CNN.
During development process, the team has several technical challenges to be addressed such as the diversity of lifting and rigging scenarios such as lifting direction, lifting equipment type, and load variety to capture and detect under suspended load zone in 2-dimensional image using straightforward logic. The first step towards building this system is collecting lifting and rigging operations image datasets from various rig areas and with different lifting scenarios and equipment. Deep learning algorithm such as Yolov4, Faster R-CNN are being used to train the model using the dataset which has been labelled on specific objects related to the lifting operation such as crane boom, crane hook, crane loads, crane tires, crane cabin, and crane box to construct under suspended load zone on the given scenarios. The Preliminary results indicate that the method has been useful to identify under suspended load zone and deliver real time automatic notification during lifting and rigging on a drilling or well intervention operations and prevent the safety risk exposure of our personnel.
