Published: December 2023

Analysis of free vibrations of functionally graded (FG) porous sigmoid sandwich plates, is considered in this paper. The plate can have a complex geometric shape and various types of fastening. To solve the problem, we used the variational-structural method (RFM), which combines the theory of R-functions and variational method of Rayleigh-Ritz. The mathematical statement of the problem is carried out within the framework of the deformation theory of plates of the first order (FSDT). Plates are considered, the outer layers of which are made of functionally graded materials (FGM), and the core is isotropic. For different models of porosity distribution (sigmoid uniform and nonuniform), analytical expressions were obtained to calculate the effective properties of FGM. For rectangular plates, a comparison of the obtained results with known results obtained using other approaches is shown. Calculations for plates with a complex shape are presented in the form of tables and graphs. The influence of the volume fraction of ceramics, the different types Of FGM and the coefficient of porosity on the natural frequencies of the plate is analyzed.

Authors: Zamula Olena , Zamula Oleksii , Uhrimova Iryna 
Published: December 2023

The paper proves the need to change approaches to personnel management in modern conditions, since there is a change in certain factors influencing the organizational behavior of employees of enterprises, namely: the number of people with disabilities is increasing in Ukraine, the labor potential of the social sphere is decreasing due to the mobilization and forced migration of specialists from various spheres of economic activity.
It has been proven that it is also necessary, among other work with the personnel of enterprises based on the concept of sustainable development, to highlight as a separate component the formation of sustainable tolerance for people with disabilities, as well as laying the foundations for inclusive employment when concluding employment contracts with them. Inclusive employment should be understood as the process of employment of persons with disabilities.
The executive and legislative power in Ukraine take care of employment of people with disabilities, but this initiative should be supported by business and the public. The objective of managers in this field is to develop staff development programs, which should include not only tools for employees to acquire professional and specialized competencies. Such programs should be aimed at forming a holistic view of both the technical and economic aspects of interaction in the process of realizing their knowledge and skills in order to achieve the goals of the organization, and about the social and environmental consequences of their behavior. Therefore, staff training and education should be carried out taking into account the latest scientific achievements in the field of sustainable development, in particular, in terms of encouraging ethical behavior of staff in relation to employees with disabilities.
Surgery and the Aging Orthopaedic Surgeon

Published: December 2023

➤ Aging is associated with well-documented neurocognitive and psychomotor changes.➤ These changes can be expected to impact the skill with which orthopaedic surgeons continue to perform surgical procedures.➤ Currently, there is no standardized approach for assessing the changes in surgical skills and clinical judgment that may occur with aging.➤ Oversight by the U.S. Equal Employment Opportunity Commission, the impact of the Age Discrimination in Employment Act, and the current legal climate make it difficult to institute a mandatory assessment program.➤ The regularly scheduled credentialing process that occurs at each institution can be the most effective time to assess for these changes because it utilizes an established process that occurs at regularly scheduled intervals.➤ Each department of orthopaedic surgery and institution should determine an approach that can be utilized when there is concern that a surgeon’s surgical skills have shown signs of deterioration.
Relationship Between Residual Saturations and Wettability Using Pore-Network Modeling
Authors: Purswani Prakash , Johns Russell T. , Karpyn Zuleima T. 
Published: December 2023

Summary
The relationship between residual saturation and wettability is critical for modeling multiphase processes like enhanced oil recovery, CO2 sequestration, and geologic storage of hydrogen. The wetting state of a core is often quantified through Amott indices, which are estimated from the ratio of the saturation fraction that flows spontaneously to the total saturation change that occurs due to spontaneous flow and forced injection. Observations from traditional coreflooding experiments show a minimum in the trends of residual oil saturation (Sor) around mixed-wet conditions. Amott indices, however, provide an average measure of wettability because of their intrinsic dependence on a variety of factors such as the initial oil saturation, aging conditions, rock heterogeneity, etc. Thus, the use of Amott indices could potentially cloud the observed trends of residual saturation with wettability.
Using pore-network modeling (PNM), we show that Sor varies monotonically with the contact angle, which is a direct measure of wettability. That is, for fixed initial oil saturation, the Sor decreases monotonically as the reservoir becomes more water-wet (decreasing contact angle). Further, the calculation of Amott indices for the PNM data sets shows that a plot of the Sor vs. Amott indices also shows this monotonic trend, but only if the initial oil saturation is kept fixed. Thus, for the cases presented here, we show that there is no minimum residual saturation at mixed-wet conditions as wettability changes.
In this research, we employ a numerical approach to quantify trends of Sor against the traditional definition of wettability. Through the analysis of our numerical work and literature experiments, we find that under isolated conditions (constant initial saturation), linear trends exist between Sor and wettability. This can have important implications for low salinity waterflooding, water-alternating-gas enhanced oil recovery, or CO2 sequestration where the effects of wettability are critical to understand phase trapping.
Bi-Objective Optimization of Subsurface CO2 Storage with Nonlinear Constraints Using Sequential Quadratic Programming with Stochastic Gradients
Authors: Nguyen Quang Minh , Onur Mustafa , Alpak Faruk Omer 
Published: December 2023

SummaryThis study focuses on carbon capture, utilization, and sequestration (CCUS) via the means of nonlinearly constrained production optimization workflow for a CO2-enhanced oil recovery (EOR) process, in which both the net present value (NPV) and the net present carbon tax credits (NPCTC) are bi-objectively maximized, with the emphasis on the consideration of injection bottomhole pressure (IBHP) constraints on the injectors, in addition to field liquid production rate (FLPR) and field water production rate (FWPR), to ensure the integrity of the formation and to prevent any potential damage during the life cycle injection/production process. The main optimization framework used in this work is a lexicographic method based on the line-search sequential quadratic programming (LS-SQP) coupled with stochastic simplex approximate gradients (StoSAG). We demonstrate the performance of the optimization algorithm and results in a field-scale realistic problem, simulated using a commercial compositional reservoir simulator. Results show that the workflow can solve the single-objective and bi-objective optimization problems computationally efficiently and effectively, especially in handling and honoring nonlinear state constraints imposed onto the problem. Various numerical settings have been experimented with to estimate the Pareto front for the bi-objective optimization problem, showing the trade-off between the two objectives of NPV and NPCTC. We also perform a single-objective optimization on the total life cycle cash flow, which is the aggregated quantity of NPV and NPCTC, and quantify the results to further emphasize the necessity of performing bi-objective production optimization, especially when used in conjunction with commercial flow simulators that lack the capability of computing adjoint-based gradients.
Single-cell CRISPR screening characterizes transcriptional deregulation in T-cell acute lymphoblastic leukemia

Published: December 2023

Abstract
T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive type of leukemia caused by accumulation of multiple genetic alterations in T-cell progenitors. However, for many genes it remains unknown how their mutation contributes to disease development. Therefore, we performed two single-cell CRISPR screens in primary pro-T cells ex vivo to study the transcriptional impact of such loss-of-function alterations and link this with effects on cell fitness. The various perturbations were clustered based on their effects on E2F/MYC or STAT/NOTCH signatures, which play a defining role in driving T-cell proliferation. Many of the perturbations resulted in positive effects on the STAT and NOTCH signatures, and were predicted to function as haploinsuffient tumor suppressors in T-ALL. Additionally, Spi1 was identified as an essential gene for pro-T cell survival, associated with deregulation of the MYC signature and epigenetic consequences. In contrast, Bcl11b was identified a strong tumor suppressor gene in immature T lymphocytes, associated with deregulation of NF-kB and JAK/STAT signaling. We found a correlation between BCL11B expression level and JAK/STAT pathway mutations in T-ALL patients, and demonstrated oncogenic cooperation between Bcl11binactivation and JAK3 hyperactivation in pro-T cells. Altogether, these single-cell CRISPR screens in pro-T cells provide insight in the mechanisms of transcriptional deregulation caused by genetic alterations in T-ALL.

Published: December 2023

Abstract

The incorporation of residues in cement matrices is a viable alternative in obtaining new products for civil construction and a sustainable solution for the disposal of materials discarded by industries. In this context, the objective of the study was to evaluate the potential use of quartzite and particles of Hevea brasiliensis treated with aluminum sulfate [Al2(SO4)3] in the production of cement-wood panels. Quartzite residues and Hevea brasiliensis wood particles were obtained and characterized. The wood particles were mineralized with Al2(SO4)3 at a concentration of 9%. The panels were produced with CPV-ARI Portland cement, calcium chloride (CaCl2) as additive, treated wood particles and addition of quartzite in different proportions (0, 10, 20 and 40%), totaling four treatments. The physical-mechanical and microstructural properties of the panels were determined. The mineralization of the particles contributed to the adherence to the wood-cement. The incorporation of 20% quartzite contributed to the improvement in water absorption and thickness swelling of the panels and in the increase in the modulus of elasticity (MOE) and modulus of rupture (MOR) values. The cement-wood panels were suitable for non-structural and internal use, requiring further studies to evaluate alternative methods of replacing these residues.
Theoretical study on copper adsorption on ZnO surfaces for CO2 hydrogenation to methanol
Authors: Salmi Mustafa Al 
Published: December 2023

Abstract

The study of Cu on ZnO surfaces is a topic of ongoing research due to the importance of Cu as a promoter in the low-temperature synthesis of methanol, the water-gas shift process, and methanol steam reforming. The role of ZnO in supporting the stabilization of the Cu atoms and promoting the CO2 hydrogenation reaction is multifaceted and involves a range of physical and chemical factors. In this work, we used density functional theory (DFT) calculations to investigate the Cu adsorption on ZnO surfaces on different sites. Bader charge analysis, adsorption energy, and phonon inelastic neutron scattering (INS) associated with most stable systems were calculated and compared with previous theoretical and experimental results. We found that atomic Cu adsorption on hollow site of ZnO(111) is the most stable site and most favorable site for Cu adsorption comparing to other ZnO surfaces. This is due to the strong metal-oxygen interaction between Cu and the ZnO surface. The results suggest that the Cu/ZnO catalyst with Cu atoms at hollow site is most likely to be active for CO2 hydrogenation. We concluded that further studies are needed to investigate the catalytic activity of this catalyst under realistic reaction conditions with realistic models of Cu supported on ZnO.
On-surface synthesis and characterization of anti-aromatic cyclo[12]carbon and cyclo[20]carbon

Published: December 2023

Abstract
Cyclo[n]carbons (Cn) have recently attracted significant attentions owing to their geometric and electronic structures remaining largely unexplored in the condensed phase1-15. On-surface synthesis has demonstrated advantage for the generation of a series of cyclocarbons, for example, C1816,17, C1618, C1419, C1019 on the NaCl surface, and their geometric structures have been revealed in real space. However, endeavors to synthesize larger cyclocarbons (e.g., C20 or C24) have encountered difficulties owing to the unstability of precursor molecules18. Meanwhile, it has been extremely challenging to probe the electronic structures of cyclocarbons due to their high mobilities on the NaCl surface. In this study, we focus another two anti-aromatic cyclocarbons, the last and the next homologue of C16, that is, C12 and C20. By designing two fully halogenated molecular precursors both including 4-numbered rings, we further extend the on-surface retro-Bergman ring-opening reaction, and successfully produce the C12 and C20. Such a strategy is also very recently followed by Gross and Anderson's groups to produce C1320. The polyynic structures of C12 and C20 were unambiguously revealed by bond-resolved atomic force microscopy (AFM). More importantly, subtly positioning the C20 molecule into an “atomic fence” formed by Cl clusters allows to experimentally probe its frontier molecular orbitals, yielding a HOMO-LUMO bandgap of 3.8 eV measured from scanning tunneling spectroscopy. Our work may open up the field by easier synthesis of a series of cyclocarbons via on-surface retro-Bergman ring-opening strategy.

Abstract

Compound bioactivity plays an important role in different stages of drug development and discovery. Existing machine learning approaches have poor generalization ability in compound bioactivity prediction due to the small number of compounds in each assay and incompatible measurements among assays. Here, we propose ActFound, a foundation model for bioactivity prediction trained on 1.6 million experimentally measured bioactivities and 35,644 assays from ChEMBL and BindingDB. The key idea of ActFound is to employ pairwise learning to learn the relative value differences between two compounds within the same assay to circumvent the incompatibility among assays. ActFound further exploits meta-learning to jointly optimize the model from all assays. On six real-world bioactivity datasets, ActFound demonstrates accurate in-domain prediction and strong generalization across datasets, assay types, and molecular scaffolds. We also demonstrated that ActFound can be used as an accurate alternative to the leading physics-based computational tool FEP+(OPLS4) by achieving comparable performance when only using a few data points for fine-tuning. The promising results of ActFound indicate that ActFound can be an effective foundation model for a wide range of tasks in compound bioactivity prediction, paving the path for machine learning-based drug development and discovery.
Visible-light-induced photocatalysis of copper phthalocyanines on cotton fibre
Authors: LUK Anson M.Y. , XIN John H. 
Published: December 2023

Abstract
There are various copper phthalocyanine (CuPc) dyes, which are the copper phthalocyanines (CuPcs) with different substituents, commonly available on the market. Several CuPc dyes were applied to cellulosic fibre for studying their photocatalytic activities by using stain decolourisation methods. Even though the molar quantity of each CuPc derivative on cotton fabric were controlled to be equivalent, there were great difference on their photocatalytic activities. Distinct extents of the CuPc molecules dissociated by the cellulosic medium, owing to different CuPc molecular structures, were observed via absorption spectroscopic analyses. Liquid chromatography-mass spectrometry (LC-MS) was employed to determine the molecular structures of the CuPcs. A novel elution profile, termed as “double-isocratic” method, was developed to separate the relatively complex mixtures of the CuPc compounds, to prevent interference against mass spectrometric detection by buffers and ion-pairing reagents. The stain decolourisation performance of CuPc dyes were also compared to one of the traditional photocatalysts, titanium dioxide (TiO2), under visible light. Stronger photocatalytic activity was exhibited by CuPc-functionalised cottons than the TiO2-coated cotton; convincing visible-light-catalytic effects were demonstrated by CuPcs on cotton under visible light. The outcomes of this study can make contributions to aggregation and photocatalytic studies of phthalocyanines in cellulosic medium; and the CuPcs defined with well-dissocated structures can be applied for functional cellulosic textiles triggered by visible light.

Abstract
The oncogenic properties of members belonging to the forkhead box (FOX) family have been extensively documented in different types of cancers. In this study, our objective was to investigate the impact of FOXP3 on glioblastoma multiforme (GBM) cells. By conducting a screen using a small hairpin RNA (shRNA) library, we discovered a significant association between FOXP3 and ferroptosis in GBM cells. Furthermore, we observed elevated levels of FOXP3 in both GBM tissues and cell lines, which correlated with a poorer prognosis. FOXP3 was found to promote the proliferation of GBM cells by inhibiting cell ferroptosis in vitro and in vivo. Mechanistically, FOXP3 not only directly upregulated the transcription of GPX4, but also attenuated the degradation of GPX4 mRNA through the linc00857/miR-1290 axis, thereby suppressing ferroptosis and promoting proliferation. Additionally, the FOXP3 inhibitor epirubicin exhibited the ability to impede proliferation and induce ferroptosis in GBM cells both in vitro and in vivo. In summary, our study provided evidences that FOXP3 facilitates the progression of glioblastoma by inhibiting ferroptosis via the linc00857/miR-1290/GPX4 axis, highlighting FOXP3 as a potential therapeutic target for GBM.

Abstract

Many efforts have sought to apply laboratory in vitro evolution (LIVE) to natural nucleic acid (NA) scaffolds to directly evolve functional molecules. However, synthetic biology can move beyond natural NA scaffolds to create molecular systems whose libraries are far richer reservoirs of functionality than natural NAs. For example, "artificially expanded genetic information systems" (AEGIS) add up to eight nucleotides to the four found in standard NA. Even in its simplest 6-letter versions, AEGIS adds functional groups, information density, and folding motifs that natural NA libraries lack. To complete this vision, however, tools are needed to sequence molecules that are created by AEGIS LIVE. Previous sequencing approaches, including approaches from our laboratories, exhibited limited performance and lost many sequences in diverse library mixtures. Here, we present a new approach that enzymatically transforms the target AEGIS DNA. With higher transliteration efficiency and fidelity, this Enzyme-Assisted Sequencing of Expanded Genetic Alphabet (ESEGA) approach produces substantially better sequences of 6-letter (AGCTZP) DNA than previous transliteration approaches. Therefore, ESEGA facilitates precise analysis of libraries, allowing 'next-generation deep sequencing' to accurately quantify the sequences of 6-letter DNA molecules at single base resolution. We then applied ESEGA to three tasks: (a) defining optimal conditions to perform 6-nucleotide PCR (b) evaluating the fidelity of 6-nucleotide PCR with various DNA polymerases, and (c) extending that evaluation to AEGIS components functionalized with alkynyl and aromatic groups. No other approach at present has this scope, allowing this work to be the next step towards exploiting the potential of expanded DNA alphabets in biotechnology.
