Weighted Compressive Sensing Applied to Seismic Interferometry: Wavefield Reconstruction Using Prior Information
Authors: Saengduean Patipan , Snieder Roel , Wakin Michael B. 
Published: March 2024

Abstract
Seismic interferometry is widely used for passive subsurface investigation using seismic noise. The technique requires much storage for long noise records to suppress interferometric noise, which consists of spurious arrivals that do not correspond to the inter-receiver surface waves. Such long recordings may not be available in practice. Compressive sensing (CS), which is a wavefield reconstruction technique operating on incomplete data, may increase the availability, and reduce storage limitations of long noise time series. Using a numerical example of a linear array surrounded by sources and the Fourier basis for a sparse transform, we show that inter-receiver wavefields can be recovered at the locations where seismometers are unavailable, reducing the storage required for interferometry. We propose and develop a weighted CS algorithm that helps suppress the spurious arrivals by incorporating a priori information about the arrivals of surface waves that can be expected.
I want to break free: Successor Emancipation in Family Business
Authors: RADU-LEFEBVRE Miruna , Lefebvre Vincent 
Published: March 2024

Family business successors live at the nexus of past, present and future, nourished and inspired by past legacies while also craving to build a brand-new future. The senior generation is generally the guardian of firm continuity in charge of preserving past achievements, whereas the next generation might dream about introducing change and innovation within the current landscape of the family firm. Yet these attempts too often trigger resistance and anxiety in the senior generation, who might respond with increasing control and suspicion to any tentative of challenging the status quo such as transforming current products, services, business models, or organizational structures. Successors operate at the intersection of these opposite forces of conservatism and reform, and one of their major issues is that they need to handle them effectively, that is without jeopardizing family relations and harmony nor losing themselves into the process. Unless they succeed in doing so, succession failure might follow. By combining two different streams of literature grounded in distinct disciplines, namely succession literature in family business and emancipation literature in entrepreneurship, we reveal successor emancipation as a novel explanation of why successions fail and offer some practical advice on how to handle these tensions in intra-family succession.

A mental health issue that has been of concern to the public in recent years is bipolar mental disorder. The disorder has an impact on increasing mortality rates, especially death by suicide. One of the Indonesian movies that raised the theme of bipolar mental disorder is the movie Ku Kira Kau Rumah. This research aims to find out how the audience perceives the content of the message, especially regarding Bipolar mental disorder in the movie Ku Kira Kau Rumah.
This research uses a descriptive qualitative approach with the method of reception analysis by Stuart Hall based on three categories namely Dominant Hegemonic Position, Negotiate Position and Oppositional Position using primary data sources as the main source. The data collection techniques used were interviews with eight informants and documentation. The data analysis technique used is the Miles and Huberman model including data reduction, data display and conclusion drawing and the data validation technique is source triangulation.
Based on the results of the research data analysis, it was concluded that two informants were in the dominant hegemonic position, meaning that the two informants approved the message conveyed. Then three informants are in a positive negotiated position, meaning that the informant tends to agree with the message conveyed in the film and the last three informants are in an oppositional position, which means that the informant who is in the positive position does not agree with the message conveyed in the film.

Published: March 2024

Summary
Nanoscale plugging materials are commonly used in the petroleum industry to seal microfractures and pores within shale formations, thereby maintaining wellbore stability and preventing drilling accidents caused by formation collapse. However, the influence of inorganic salts present in the formation and drilling fluids on the dispersion properties of nanoscale plugging materials often affects their sealing performance. In this study, we focus on investigating the influence of three commonly encountered inorganic salts in the drilling process—sodium chloride (NaCl), potassium chloride (KCl), and calcium chloride (CaCl2)—on the dispersibility and sealing performance of commonly used nanoscale plugging materials such as nanosilica and nanoemulsions in shale formations, exploring the dispersion and sealing mechanisms. Zeta potential is used as a characterization parameter, and molecular dynamics simulations are used to study the effects and mechanisms of inorganic salt ions on the dispersion of plugging materials. Filtration and pressure transmission experiments are conducted to investigate changes in their sealing performance. Scanning electron microscopy (SEM) is used to observe the microstructure of the formed filter cake, providing insights into the dispersion and sealing mechanisms. The results reveal that nanosilica agglomerates at zeta potentials ranging from −18 mV to −15.5 mV, resulting in an increase in filtration volume from 93.3 mL to 171.1 mL and downstream stable pressure transmission rising from 330.98 psi to 551.98 psi. Nanosilica (modified with KH570) agglomerates at zeta potentials of −10.3 mV to −9.9 mV, leading to an increase in filtration volume from 93.1 mL to 171 mL and downstream stable pressure transmission rising from 326.98 psi to 553.35 psi. The average gyration radius of the KH570 molecule decreases from 0.347 nm to 0.337 nm under the influence of inorganic salts. In contrast, the dispersion stability of nanoscale emulsions is independent of zeta potential; however, under the influence of inorganic salts, the filtration volume increases from 92.2 mL to 170.9 mL and downstream stable pressure transmission rises from 293.03 psi to 550.98 psi. The average gyration radius of nanoscale emulsion monomer molecules decreases from 0.340 nm to 0.336 nm under the influence of inorganic salts. Microscopic examination of filter-cake morphology shows that inorganic salts not only affect dispersion stability, leading to the aggregation of nanomaterials and influencing sealing performance, but also reduce the deformability of organic particles, thereby affecting sealing performance. The properties obtained in this study provide theoretical references for the sealing performance of nanomaterials in drilling fluids, offering significant value for researchers and field engineers in selecting nanoscale plugging materials for shale formations.

Abstract

Immune checkpoint blockade therapy aims to activate the immune system to eliminate cancer cells. However, clinical benefits are only recorded in a subset of patients. Here, we leveraged genome-wide CRISPR/Cas9 screens in a Tumor-Immune co-Culture System focusing on triple-negative breast cancer. We revealed that NEDD8 loss caused a vulnerability to nivolumab. Genetic deletion of NEDD8 only delayed cell division initially but cell proliferation was unaffected after recovery. Since the NEDD8 gene is commonly essential, we validated this paradigm shift with additional CRISPR screens and uncovered significantly enhanced immunogenicity in NEDD8 deficient cells using proteomics. In immunocompetent mice, PD-1 blockade lacked efficacy against established EO771 breast cancer tumors. In contrast, we observed curative effects mediated by CD8+ T cells against NEDD8 deficient EO771 tumors after PD-1 blockade. In essence, we provide evidence that NEDD8 is conditionally essential in triple-negative breast cancer and presents a synergistic drug target for PD-1/L1 blockade therapy.

Abstract
Three grades of xanthates of β-cyclodextrin (β-CD) viz. β-CDX1 β-CDX2 and β-CDX3 have been synthesized by the rection of β-CD with CS2 in alkaline medium (NaOH), through xanthation process. The synthesized β-CDXs have been characterized by UV, FTIR, 1HNMR, DSC, ΔpHPZC and SEM analysis. Further, β-CDXs and raw β-CD has been used for the heavy metals removal (Cu2+ and Ni2+) and also lignin removal from lignin enriched paper industry wastewater (LEPIW). The maximum % removal of β-CD, β-CDX1, β-CDX2 and β-CDX3 have been found to be 73.6, 91.9, 93.4 & 95.8% for Cu2+ ion and 65.8, 88.6, 91.3 & 94.1% for Ni2+ ion at optimum adsorbent dosage 2.0 g/L, pH 6.5, initial concentration 1000 mg/L, temperature 45 oC for Cu2+ and 55 oC for Ni2+, and contact time: 80 min for Cu2+ and 100 min for Ni2+ ion respectively. While LEPIW treatment efficacy of 54, 77, 83 and 86% has been noticed (initial COD: 2.0 g/L, pH: 7, optimum temperature: 40°C at 80 min operating time) for β-CD, β-CDX1, β-CDX2 and β-CDX3 respectively. The calculated data fitted well with Langmuir isotherm model confirming the adsorption of Cu2+ & Ni2+ ions onto the β-CDXs adsorbent is monolayer. The rate of adsorption of heavy metals (Cu2+ and Ni2+) on the β-CDXs adsorbent has been controlled by kinetic model of Pseudo second order indicating the chemisorption. The optimal adsorption capacities of β-CD, β-CDX1, β-CDX2 and β-CDX3 has been found to be 357.14, 473.93, 510.20 & 534.75 mg/g for Cu2+ and 294.11, 384.61, 408.16 & 423.72 mg/g and for Ni2+ ions, respectively.
End-user perspectives on the acceptability, feasibility, and health equity impacts of Mycobacterium tuberculosis specific antigen-based skin tests compared to interferon gamma release assays and the tuberculin skin test: A semi-structured interview study
Authors: Loveys Kate , Chan Amy Hai Yan , Hamada Yohhei , Rangaka Molebogeng X 
Published: March 2024

Abstract

Background
Antigen-based skin tests (TBST) have been developed for detecting Mycobacterium tuberculosis (TB) infection (TBI). TBST may have comparable sensitivity and specificity to Interferon Gamma Release Assays (IGRA), the gold standard in TBI testing. However, they are portable and low cost, and may be better suited for use in large scale screening programmes and in resource-limited settings. To date, there is limited evidence on stakeholder values and preferences, and the acceptability, feasibility, and health equity impacts of TBST relative to existing TBI tests.
Methods
We explored end-user values and preferences, and perspectives on the acceptability, feasibility, and health equity impacts of TBST compared to IGRA and tuberculin skin tests (TST). 20 semi-structured interviews were conducted with TB healthcare consumers and providers from low-middle and high-income countries between Sept 07, 2021 and Nov 01, 2021. Data were transcribed verbatim and coded by two independent raters using inductive thematic analysis.
Results
Seven consumers and 13 providers of TB healthcare were interviewed from 11 low-middle and 9 high-income countries. Healthcare consumers and providers shared similar values and preferences towards TBI tests. Stakeholders valued TBI test accuracy, convenience, cost, patient experience, and resource requirements. Overall, TBST were viewed as more acceptable and equally feasible to TST, with greater health equity benefits from improved sensitivity and specificity. TBST were generally viewed to be less acceptable than IGRA due to some undesirable aspects of the patient experience (eg requires two patient visits, stigma and discomfort from the arm welt). TBST were viewed as more feasible than IGRA in resource-limited settings due to their portability and low cost. However, TBST are unlikely to replace IGRA in high-resource settings where the resourcing is already in place to support IGRA use.
Conclusions
TBST may be a more accurate alternative to TST that could be used in large scale screening programmes and in resource-limited healthcare settings. IGRA are likely to remain the preferred TBI test in high-resource healthcare settings as they have comparable sensitivity and specificity, and the resourcing is already in place for IGRA use. These findings may inform decision-making on TBI tests in global public healthcare.

Published: March 2024

Abstract

Background
Reproductive-age women in New Juaben Municipality of the Eastern Region of Ghana have been found to have a high rate of unplanned pregnancies despite the availability of modern contraceptives. However, no study has been done in the Municipality regarding the perception, threats, barriers, or challenges these women face in utilizing modern contraceptive services. Therefore, this study sought to identify and help address critical issues faced by reproductive-age women in the use of modern contraceptives.
Methods
The study adopted a basic qualitative approach and collected data through individual interviews. The participants were purposefully selected and informed consent was obtained. After the transcription of interviews, the data were analyzed inductively using thematic content analysis techniques.
Results
The participants acknowledged the negative consequences of unintended pregnancy, and they expressed the desire to use modern contraceptives to either prevent unintended pregnancy or space their births. The study also established that the low utilization of modern contraceptive services is influenced by low knowledge, misconceptions, religious beliefs, and perceptions about the side effects of using modern contraceptives.
Conclusions
It is necessary for all health professionals to create more awareness and intensify education on modern contraceptive methods while taking the health belief context into consideration.
Exceptional precision of LC passive wireless sensors using nonlinear PT-symmetric configurations
Authors: Huang Qing-An , Chen Dong-Yan , Dong Lei 
Published: March 2024

Abstract
An inductor–capacitor (LC) passive wireless sensor is essential to physical, chemical, and biological sensing for scenarios where physical access is difficult. For emerging applications such as implantable, wearable, or other devices with geometrical constraints, the resulting small inductor coils weaken the strength of interrogation signals. It is therefore highly desired to enhance the sensitivity. Exceptional points (EPs) of parity-time (PT) symmetric LC systems featuring the linear loss and gain have been recently utilized for enhancing sensing. However, the EP sensing scheme might bring about fundamental resolution limits and noise enhancement. Here, we show, using PT-symmetric LC configurations of the linear loss and saturable gain, that the responsivity has a cube-root singularity distinct from a square-root singularity of the linear EP-scheme. The saturable gain allows the system to automatically achieve a steady-state oscillation, which eliminates the imaginary part of the eigenfrequencies and significantly suppresses the noise. As a result, the signal-to-noise ratio (SNR) is dramatically enhanced. Through an example of LC wireless flexible temperature sensors, we demonstrate the high SNR for the nonlinear PT-symmetric configuration. Our results resolve a debate on the effectiveness of the EP sensing scheme for LC sensors and pave the way for these types of sensor with exceptional precision.
