Abstract
The subsurface processes of enhanced oil recovery (EOR) and carbon capture and storage (CCS) involve complex geochemical interactions mainly CO2, brine, and reservoir rock. This interaction is time-dependent and could influence the wettability and thus the multiphase flow. Less attention has been given to this interaction caused by a weak acidic environment to understand the wettability of CO2/brine/rock systems under high pressure and high temperature over time. This study aims to experimentally investigate the wettability of sandstone and carbonates in a CO2/brine environment at pressure levels between 0.1 to 10 MPa and at 50°C temperature. To this end, a 2-week time duration was considered for aging samples at 50 °C and 10 MPa, for contact angle measurements on theCO2/brine/rock system. The results indicate a significant contact angle shift from weakly water-wet to weakly CO2-wet as a result of geochemical interaction. Particularly, the change in contact angle in carbonates is much higher than the contact angle noticed in sandstone. In addition, there is an increase in contact angle with the pressure, which is consistent with the interfacial tension measurement. Interestingly, the retention of brine on the rock surface shows interesting results in the presence of CO2 – less in sandstone than more in carbonates. This research would help us better understand changes in wettability and thus develop more effective strategies for storage prospectives. In addition, more data is needed to acquire, so that predictive models can be designed to simulate and optimize fluid dynamics for CO2 injection and storage applications.

Abstract
The understanding of close-to-reality fracture geometry and conductivity is needed to make decisions and drive the strategy of the hydraulic fracturing. In most cases, the pressure match is utilized even though it does not provide a unique solution. The acquisition of one or more fixed parameters, such as fracture height and length, from surveillance will enable a definition of hydraulic fracture geometry and conductivity that is close to reality.
Multiple height measurements such as those obtained by radioactive tracer have been implemented to provide post-fracturing height measurement surveillance. However, the tracer result does not provide real-time fracture propagation behavior. Real-time surveillance could enable making decisions for timely intervention treatment execution. Real-time intervention could avoid propagation of the fracture into unwanted zones and could minimize the risk of screenout due to height growth. Fiber-optic data collection is proposed as a real-time surveillance method.
Fiber-optic surveillance methods could help the decision-making process during hydraulic fracturing treatment and production evaluation in multiple-stage fracturing. In the application, the real-time data could trigger real-time intervention to minimize the impact of the screenout. During the post-treatment evaluation, understanding the screenout development process will enable devising a fit-for-purpose strategy for each formation in the next well. The real-time harvesting of data during post-fracturing production will make possible a qualitative understanding of the zone contributions and behavior of each stage at any time of the well life and will provide insight for the field development plan.
This work introduces a surveillance strategy optimization approach that will be able to provide understanding of the fracture geometry and zonal contribution through real-time measurement until the end of the well life. It also provides insight into the use of real-time data acquisition to understand the fracture and the production behavior and recommendations based on fiber-optic surveillance deployment.

Abstract
The storage of CO2 is controlled by a variety of parameters. While it is impossible to quantify or predict their distribution across the inter-well space their accurate measurement in known points (wells and core) are obviously beneficial for making more accurate forecasts. While all the requirements for storage characterization are stated clearly in guiding documents (as in ISO 27914 or DNV RP-J203) and national regulations and codes the specifics as to how to approach lab studies are not included. Therefore, in order to ensure the safety and operational capability of a CO2 storage project a part of lab studies design is proposed with corresponding results and their interpretation. Since the main goal of these projects is to reduce greenhouse gases emission to alleviate climate change and consequently they are bound to be verified across the world an attempt to come to universally accepted approach seems justified and necessary.
CO2 storage is influenced by various parameters, which are difficult to quantify or predict in the inter-well space. However, their precise measurement in known locations (such as wells and core samples) can enhance the accuracy of storage forecasts. Although the general requirements for storage characterization are clearly defined in guidance documents (e.g., ISO 27914 or DNV RP-J203) and national regulations and standards, the specific methods for conducting laboratory studies are not specified. Therefore, this paper proposes a partial design of laboratory studies for a CO2 storage project, along with the results and their interpretation. The main objective of these projects is to mitigate climate change by reducing greenhouse gas emissions, which requires global verification. Hence, developing a universally accepted approach is both reasonable and necessary.

Abstract
With the increasing need for highly integrable and energy-efficient hardware for cutting-edge applications, such as neuromorphic and in-memory computing, reconfigurable devices with multi-functional operations are essential for these applications, enhancing performance and area efficiency. However, traditional reconfigurable devices suffer from limited functionality and circuit incompatibility due to the adoption of multiple gates, leading to increased system complexity and manufacturing costs. This work demonstrates reconfigurable floating-gate field-effect transistors (R-FGFETs) based on van der Waals (vdW) heterostructure to implement highly integrable and reconfigurable circuits for in-memory computing with minimum overhead. By modulating the charge trapping within the graphene floating gate using a single gate terminal, R-FGFETs can attain four distinct electrical conducting states: metallic, n- and p-type semiconducting, and insulating. By incorporating these R-FGFETs into reconfigurable combinatorial computing units, programmable logic and arithmetic operations, including 16 Boolean logic gates, addition, subtraction, and comparison, are feasibly achieved with minimal overhead. Also, a novel method is proposed to address voltage mismatch between input and output through programming voltage-dependent threshold voltage shift, facilitating efficient connections between logic gates. This work offers a potential pathway for highly integrating a reconfigurable processor based on vdW heterostructures, thus providing an area- and energy-efficient solution.

Abstract
Delivery of therapeutic stem cells to treat bone tissue damage is a promising strategy that faces many hurdles to clinical translation. Among them is the design of a delivery vehicle which promotes desired cell behavior for new bone formation. In this work, we describe the use of an injectable microporous hydrogel, made of crosslinked gelatin microgels, for the encapsulation and delivery of human mesenchymal stem cells (MSCs) and compared it to a traditional nonporous injectable hydrogel. MSCs encapsulated in the microporous hydrogel showed rapid cell spreading with direct cell-cell connections whereas the MSCs in the nonporous hydrogel were entrapped by the surrounding polymer mesh and isolated from each other. Microporous hydrogel induced more robust osteogenic differentiation of MSCs and calcium mineral deposition than the nonporous hydrogel confirmed by alkaline phosphatase (ALP) assay and calcium assay. RNA-seq confirmed the upregulation of the genes and pathways that are associated with cell spreading and cell-cell connections, as well as the osteogenesis in the microporous hydrogel. These results demonstrate that the microgel-based injectable hydrogels can be useful tools for therapeutic cell delivery for bone tissue repair.

Abstract
A multicenter study of nonmetastatic castration-resistant prostate cancer (nmCRPC) was conducted to examine the prognostic to identify the optimal cut-off value of prostate-specific antigen (PSA) doubling time (PSADT) in Japanese nmCRPC. Of the 515 patients diagnosed and treated for nmCRPC at 25 participating Japanese Urological Oncology Group centers, 450 patients with complete clinical information were included. The prognostic values of clinical factors were evaluated with respect to prostate specific antigen progression-free (PFS), cancer-specific survival (CSS), and overall survival (OS). The optimal cutoff value of PSADT was identified using survival tree analysis by Python. The Median PSA and PSADT at diagnosis of nmCRPC were 3.3 ng/ml, and 5.2 months, respectively. Patients treated with novel hormonal therapy (NHT) showed significantly longer PFS (HR: Hazard Ratio 0.38, p < .0001) and PFS2 (HR 0.45, p < .0001) than those treated with vintage nonsteroidal antiandrogen agent (Vintage). The survival tree identified 4.65 months as the most prognostic PSADT cutoff point. Among the clinical and pathological factors PSADT of < 4.65 months remained an independent prognostic factor for OS (HR 2.96, p = .0003) and CSS (HR 3.66, p < .0001). Current data represented optimal cut-off of PSADT 4.65 months for a Japanese nmCRPC.

Abstract

Background: Acute kidney injury (AKI) is an important adverse event of hospitalized patients that associates high mortality and high medical cost. While accurate diagnosis and timely management of AKI is essential for improving the outcomes of in-hospital AKI, delayed diagnosis or misdiagnosis by clinicians hinders the advance in the care of AKI. To ameliorate this problem, several electronic AKI alert systems had been proposed, which had shown inconsistent effects on the outcomes of AKI. Before electronic systems could improve the outcomes of AKI, an important issue to be elucidated is to confirm their diagnostic accuracy. The purpose of the present study is to establish an easy-to-construct Computerized Algorithm for the diagnosis of renal impairment and to test its accuracy.
Methods: The present study retrospectively included 1551 hospitalized patients with serum creatinine (SCr) of > 1.3 mg/dL in Wanfang Hospital. A Computerized Algorithm was constructed to identify AKI events and CKD cases among these patients. Previous SCr tests were reviewed to define the baseline SCr level. Increased SCr level of > 1.5 times from baseline was defined as AKI. Estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73m2 for > 90 days was defined as CKD. The standard diagnoses were made by experienced nephrologists according to the same criteria. The discharge diagnoses made by the attending physician was defined as clinician’s diagnoses. The diagnoses made by Computerized Algorithm and the clinicians were compared with the researcher’s diagnoses to define their accuracy.
Results: Of the included patients, the mean age was 73.0 years old; the in-hospital mortality was 14.8%; AKI was present in 28.6% of the patients. Regarding the diagnostic accuracy for AKI, the Computerized Algorithm achieved a sensitivity of 85.6% and a specificity of 98.8%. The main cause of false negative (FN) AKI diagnosis was that AKI occurred earlier than the outpatient visiting before the indexed hospitalization. Regarding the diagnostic accuracy for CKD, the Computerized Algorithm achieved a sensitivity of 94.7% and a specificity of 100%. The cause of FN CKD diagnosis was exclusively lack of previous eGFR records. Compared to the clinician’s diagnoses, the Computerized Algorithm exhibited significantly superior accuracy than the clinician’s diagnoses in both AKI (95.0% versus 57.0%) and CKD (96.5% versus 73.6%).
Conclusions: We developed a simple and easy-to-construct Computerized Algorithm for the diagnosis of renal impairment, which significantly improved the diagnostic accuracy of AKI and CKD than clinicians did. In future, an algorithmic approach for differential diagnosis of AKI and decision guide with be incorporated into this system.

Abstract
The aim of this work is to study the influence of the palm fibers treated with soda hydroxide solution, on the properties of the compressed earth bricks stabilized with 15% of natural pozzolana based alkaline geopolymer binder. To achieve this objective, mortars composed of treated fibers at different levels (0.1, 0.2, 0.3, 0.4 and 0.5%) for a length of 4 and 16 cm, have been developed. These different mortars with those without fibers were subjected to mechanical (dry compression, wet compression, and flexion), physical (water absorption), mineralogical (XRD, FTIR) and microstructural (SEM/EDX) characterizations after 7 and 90 days. The results obtained show that, in general the addition of fibers improves the mechanical and physical properties of compressed earth bricks stabilized with 15% of alkali-geopolymer binder. In addition, the adding of treated palm fibers does not have an influence on the mineralogical composition of the composite bricks. The observation of the diffractograms of FTIR analysis shows that these fibers have a capacity to sorption water molecules. Furthermore, the optical analysis shows that the binder used perfectly encapsulates the fibers. This situation shows that the treated fibers act perfectly as a filler in the matrix. The maximum dry compressive strength and flexural strength values are obtained with the addition of 0.4% fibers at 90 days and are 8.08 and 5.8 MPa respectively. Furthermore, an additional of 0.4% of palm fibers in earth bricks stabilized by the alkaline geopolymer binder based natural pozzolan is recommended for the construction of buildings.

Abstract

Background: This study aimed to compare the differences in white-to-white (WTW) values obtained using the triple-person-times caliper measurement, IOL-Master 700, Pentacam HR, and UBM before V4c Implantable Collamer Lens (ICL) Implantation. The objective of this study was to analyze the characteristics of these measurements and assess their correlation with the vault.
Methods: A total of 930 myopia patients (1842 eyes) who were interested in undergoing ICL surgery were assessed before the procedure using various instruments. The WTW measurements were obtained using a triple person-times caliper, Pentacam HR, and IOL-Master 700, whereas the angle-to-angle (ATA) measurements were obtained using UBM. The size of the ICL was subsequently calculated using triple person-times caliper measurements. The vault of the ICL was assessed using Pentacam HR three months after the surgery.
Results: The WTW was determined to be 11.31 ± 0.31mm, 11.49 ± 0.34mm, and11.86 ± 0.37mm, respectively, using the triple person-times caliper, Pentacam HR, and IOL-Master 700. The measurement of ATA was 11.58 ± 0.51mm, as done by UBM. The ICL vault was measured to be 411.49 ± 197.59 µm when examined with Pentacam HR three months after the procedure. The results from all four methods in horizontal WTW, triple person-times caliper, Pentacam HR, IOL - Master 700, and UBM, were compared and p < 0.001 was considered statistically significant. The four measures correlated well (r > 0.38, p = 0.000). The highest correlation was found between IOL-Master and Pentacam HR (r = 0.783, p = 0.00). The lowest correlation was found between UBM and Pentacam HR (r = 0.38, p = 0.00). Bland–Altman analysis showed that the 95% limits of agreement (LoA) were the triple person-times caliper and Pentacam HR (–0.59, 0.29) and the triple person-times caliper and IOL Master (–1.12,–0.03). This indicated a strong agreement between the triple person-times caliper and Pentacam HR and a lack of agreement between the triple person-times caliper and IOL Master.
Conclusions: Triple person-times caliper measurements offer excellent maneuverability, practicality, and reliable outcomes for determining ICL vaults. Measurements obtained using the triple-person caliper were less differece than those obtained using the Pentacam HR.

Abstract

Hyperspectral technology offers a promising alternative to traditional methods for investigating soil arsenic (As) contamination. However, the relationship between soil arsenic content and spectra may involve complex non-linear dynamics and data redundancy. Therefore, selecting spectral features and constructing models for rapid estimation has become a focal point in current research. In this study, soil samples were collected from an abandoned non-ferrous metal factory area, serving as the research subject, and hyperspectral data within the visible/near-infrared (400–1000 nm) range were acquired. The original spectral data underwent preprocessing using Savitzky-Golay smoothing (SG), Multiple Scattering Correction (MSC), and first-order derivative transformation (FD). Subsequently, the dataset was partitioned using the SPXY algorithm, and bands relevant to heavy metal arsenic (As) content were identified through Spearman correlation analysis.Various feature selection algorithms were then combined with the Extended Feature Algorithm (EFA) to determine the pertinent bands. Finally, a regression prediction was conducted using the selected bands as independent variables and arsenic (As) content as the dependent variable. This was achieved by constructing an Improved Particle Swarm Optimization-Support Vector Machine Regression model (IPSO-SVMR).According to the model evaluation criteria, the band combination of the ICO-SPA feature selection algorithm combined with EFA yielded an R2 of 0.87435, an RMSE of 22.374, and an RPD of 2.8211 on the validation set, indicating its superiority as the best model constructed.This study provides an effective method for the rapid estimation of heavy metal arsenic content.
Isokinetic Strength and Functional Ratio for Quadriceps and Hamstrings among Semi-Professional Athletes in UAE playing Football, Cricket, and Tennis- Biomechanical Implications
Authors: Bhatt Yogi , Hazari Animesh 
Published: April 2024

Abstract
Background
Monitoring the strength of the muscle is essential for both assessing and anticipating the state of the muscle and its functional capacity. Isokinetic strength evaluation is amongst the most widely employed techniques for assessing lower limb muscle strength in athletes. It has been determined that the hamstring-to-quadricep ratio is a crucial factor in determining the incidence of lower extremity injuries. Sports like football, cricket, and tennis have similar components in practice but may have a different involvement of the hamstring-to-quadriceps ratio. Hence, this study aims to compare the isokinetic strength of the hamstrings against the quadriceps for football, cricket, and tennis among semi-professional athletes.
Methodology:
An observational, cross-sectional study was conducted with the inclusion of participants between the ages of 18 years to 40 years, both males and females having an active athlete profile playing football, cricket, and tennis as a semi-professional (competing in inter-collegiate, national level tournaments). The minimum duration in each sport was taken as one hour per day and three to five times per week. A total of 66 participants were enrolled with 22 participants in each group for 6 months. ISOMOVE isokinetic device was used to assess the strength of dynamically contracting Quadriceps and Hamstring muscles.
Results
Age-wise distribution of players showed that age ranged between 18–40 years with 77.3% players in football, 68.2% in cricket, and 59.1% in tennis were males. The comparison for the mean peaks of isokinetic strength of all three sports suggested that higher isokinetic strength was found in football players with a mean value of 0.51 ± 0.07, followed by cricket and tennis with mean values of 0.48 ± 0.08 and 0.42 ± 0.05 respectively.
Conclusion
The isokinetic strength was found to be more in football players followed by cricket and tennis players for semi-professional athletes. The findings of the study conclude that isokinetic strength varies for the given three similar sports as the demand on the target muscle would vary specifically. A good isokinetic strength for football skills may not impart similar physiological properties for cricket and tennis. Thus, semi-professional players who play multiple games should consider the strength and training specific to sports to avoid the risk of injuries.
