An Empirical Analysis of the Capabilities for Digital Transformation Resilience in Selected Countries

Purpose: The study examined the enabling capabilities of digital transformation resilience across 61 countries from 2013 to 2022. Theoretical framework: This study draws on four theoretical perspectives: resilience theory, dynamic capabilities view, knowledge-based view theory, and diffusion of innovation theory. These theoretical lenses focus on how organizations can succeed in a changing environment. Design/Methodology/Approach: This study used secondary data from the International Institute for Management Developments (IMD), the World Digital Competitiveness Ranking, and the World Intellectual Property Organization (WIPO) Global Innovation Index (GII). The data set analyzed included information from 61 countries between 2013 to 2022. Panel data regression was used to conduct the analysis. Findings: The findings indicate that only knowledge capability has a significant relationship with digital transformation resilience technology, and future readiness was considered a non-significant enabler. Research, practical & social implications: In the digital age, governments and industries must prioritize resilience by implementing policies, developing necessary skills, providing training activities, and investing in research and development. Originality/Value: The originality of this study lies in its investigation of resilience capabilities with the new theoretical lens. Organizations must develop resilience capabilities, particularly in the realm of digital transformation. Digital transformation resilience pertains to an organization's capacity to adjust and react to changes in the dynamic environment using digital technologies.
Subsequent Device Usage and Caregiver Attitudes to Do-It-Yourself Real-Time Continuous Glucose Monitoring (DIY-rtCGM) among Children with Type 1 Diabetes 3 Months after Participation in a Randomized Controlled Trial

Aim. To assess children’s subsequent device usage and caregiver attitudes to do-it-yourself real-time continuous glucose monitoring (DIY-rtCGM) at least 3 months after completing a randomized controlled trial (RCT). Methods. A brief online questionnaire or telephone call was used to collect the subsequent device usage and caregivers’ attitudes from a total of 55 families at least 3 months after their completion of an RCT investigating DIY-rtCGM adapted from their preexisting intermittently scanned glucose sensors plus education on using DIY-rtCGM system. To be eligible for the RCT, children had to be aged 2–13 years, have type 1 diabetes ≥6 months, and be rtCGM naïve. Data collected investigated current CGM use post-RCT and attitudes/user experiences to DIY-rtCGM in the months since RCT study support ended. Results. Overall, responses from 81.8% (45/55) of caregivers were received. Mean age of children was 9.0 ± 2.7 years, and 31 (68.9%) children used insulin pumps. After 3 months, 44.4% (20/45) of responding caregivers reported ongoing DIY-rtCGM use, and of these, only 13 used DIY-rtCGM as the primary glucose monitoring method 100% of time. Of the 25 (55.6%) families who ceased DIY-rtCGM, 40% (10/25) had transitioned to commercial rtCGM. More than half of families (60%, 12/20) who continued DIY-rtCGM use had a very or extremely positive attitude toward the technology and 75% (15/20) of these families planned to continue DIY-rtCGM use. However, signal loss and sensor inaccuracy remained the major reasons among all responders both for decreased DIY-rtCGM wear time and eventual cessation. Burden of use primarily related to technical errors that could not be solved, and alarms, both of which were reported to contribute to discontinuation. Conclusions. This study highlights that, among families voluntarily using DIY-rtCGM at least 3 months following support from a trial, more than half have ceased using DIY-rtCGM, with 40% of those discontinuing switching to commercial rtCGM. While overall perceptions of DIY-rtCGM remain largely positive, burdens of use are high and contribute to discontinuation.
Effect of ephemeris errors on the accuracy of the computation of the tangent point altitude of a solar scanning ray as measured by the SAGE 1 and 2 instruments

An analysis was made of the error in the minimum altitude of a geometric ray from an orbiting spacecraft to the Sun. The sunrise and sunset errors are highly correlated and are opposite in sign. With the ephemeris generated for the SAGE 1 instrument data reduction, these errors can be as large as 200 to 350 meters (1 sigma) after 7 days of orbit propagation. The bulk of this error results from errors in the position of the orbiting spacecraft rather than errors in computing the position of the Sun. These errors, in turn, result from the discontinuities in the ephemeris tapes resulting from the orbital determination process. Data taken from the end of the definitive ephemeris tape are used to generate the predict data for the time interval covered by the next arc of the orbit determination process. The predicted data are then updated by using the tracking data. The growth of these errors is very nearly linear, with a slight nonlinearity caused by the beta angle. An approximate analytic method is given, which predicts the magnitude of the errors and their growth in time with reasonable fidelity.
Low-Profile Dual-Polarized Antenna Integrated with Horn and Vivaldi Antenna in Millimeter-Wave Band

In this paper, a dual-polarized antenna based on a substrate-integrated waveguide (SIW) horn antenna and Vivaldi antenna is proposed. The horizontal polarization (HP) is achieved by using the H-plane SIW horn antenna, while the vertical polarization (VP) is realized by a typical Vivaldi antenna etched on the surface of the SIW horn antenna. In front of the horn aperture, a dielectric lens is designed to optimize impedance matching and enhance directivity. Different feeding structures of the two polarizations are used to enhance the isolation between the two ports. The measured results demonstrate a 20.04–25.5 GHz (23.97%) overlapped dual-polarized impedance bandwidth, and the measured maximum gains of the HP and VP are 5.2 dBi and 8.2 dBi, respectively. A good isolation of 35 dB within the operating band is realized. The proposed dual-polarized antenna meets the demand to transmit and receive signals in two polarization directions simultaneously for wireless communication well.
A High 5292-PPI Pixel Circuit for Micro Displays With 10-Bit Gray Levels Realized via the Technique of Analog Sub-Frame Integral

A pixel circuit driven in small range of data voltage <inline-formula> <tex-math notation="LaTeX">$(V_{data})$ </tex-math></inline-formula> is proposed for high pixel-per-inch (PPI) micro displays, using the new driving technique of analog sub-frame integral (A-SFI) to realize the required current integrals of gray levels. This circuit runs with two analog <inline-formula> <tex-math notation="LaTeX">$V_{data}$ </tex-math></inline-formula>’s configurated by 7-bit digital-to-analog converters (DACs), outputting 10-bit integral currents by receiving a digital voltage of <inline-formula> <tex-math notation="LaTeX">$V_{sel}$ </tex-math></inline-formula> at each sub-frame that is one of eight (3-bit) equally divided from an illuminating period. With the 1-LSB of 5mV assumed, the estimated <inline-formula> <tex-math notation="LaTeX">$V_{data}$ </tex-math></inline-formula> range of 0.64V, which is apparently lower than at least 5V of a conventional circuit made by high voltage FETs (HVFETs), assists the proposed circuit in mainly constructing by the low voltage FETs (LVFETs) that are driven by about 1V; therefore, its pixel layout could be shrank for high PPI. Implementing this circuit in a 1.03-inch, high 5292PPI micro OLED panel made via that 55nm CMOS process for the validations, the simulated results over the displaying range show the <inline-formula> <tex-math notation="LaTeX">${l}$ </tex-math></inline-formula>DNL’s of within +1.15iLSB and −1.01iLSB, the iINL’s of within +1.53iLSB and −1.05iLSB, and the iAD’s of within +1.94% and −1.18%, observed the favorable linearities or deviations to the generated integral currents along 10-bit grayscales. The experimental results show the <inline-formula> <tex-math notation="LaTeX">${l}$ </tex-math></inline-formula>DNL’s of within<inline-formula> <tex-math notation="LaTeX">$3.12{l}$ </tex-math></inline-formula>LSB and <inline-formula> <tex-math notation="LaTeX">$- 1.75{l}$ </tex-math></inline-formula>LSB, and the <inline-formula> <tex-math notation="LaTeX">${l}$ </tex-math></inline-formula>INL’s of within<inline-formula> <tex-math notation="LaTeX">$3.35{l}$ </tex-math></inline-formula>LSB and <inline-formula> <tex-math notation="LaTeX">$- 2.29{l}$ </tex-math></inline-formula>LSB, validated the viability of this technique for high PPI displays.
The Role of Emotion Regulation for General Self-Efficacy in Adolescents Assessed Through Both Neurophysiological and Self-Reported Measures

Background Self-efficacy, the belief in one’s ability and capacity to organize and execute actions required to achieve desired results, is associated with adolescent academic achievement and reduced risk for psychopathology. Adolescent emotion regulation represents an important component in the relationship between self-efficacy and developmental outcomes, but the underlying neurophysiological mechanisms are poorly understood. It is unclear how emotion regulation strategies, which change with experience, and emotion regulation capacity, which is largely determined by genetics, contribute to the development of self-efficacy. Aim The present study aims to explore the relationship between emotion regulation and self-efficacy in adolescents. We hypothesize that neurophysiological emotion regulation capacity moderates the relationship between emotion regulation strategies and self-efficacy. Methods The present study applied a cross-sectional design. A sample of high-school students (N = 45, nfemale = 31, age = 17–18) provided answers on the General Self-Efficacy Questionnaire and the Emotion Regulation Questionnaire. Vagal tone was used as an indicator for emotion regulation capacity. Results In the initial correlational analysis, reappraisal, but not expressive suppression nor vagal tone was associated with self-efficacy. Vagal tone was not associated with any self-report measures of emotion regulation or self-efficacy. Contrary to our hypothesis, vagal tone did not moderate the relationship between emotion regulation and self-efficacy. Conclusion This is the first study assessing the relationship between neurophysiological indicators of emotion regulation and self-efficacy. Our results do not indicate that vagal tone moderates the relationship between emotion regulation strategies and general self-efficacy. Future studies should also assess the possible influence of metacognition and interoception on relationships.
Vortex induced transport phenomena in flows past micropins

The potential of vortex shedding behind cylindrical micropins to enhance mixing at the microscale is investigated. The confinement present in microchannels may prevent or delay the formation of vortices and weaken the performance of such a passive micromixer. Thus, the onset of vortex shedding in confined flows in micromixers need be elucidated to optimize mixing performance. In this work, the flow past a single cylindrical pin in microchannels with different levels of confinement was studied experimentally using a custom high-speed micro particle-image velocimetry (µPIV) system. This system can resolve the instantaneous velocity fields and the corresponding vortex shedding frequencies. Results show that the onset of vortex shedding is delayed by enhancing the vertical confinement for a channel width of three pin diameters. However, when vortex shedding is present, the vortex shedding frequency and corresponding Strouhal numbers (St) are greater in more confined channels for the same Reynolds number (Re). Finite-Time Lyapunov Exponent (FTLE) analysis was performed on the acquired velocity fields to estimate the mixing performance. Preliminary results with a channel three pin diameters wide and three pin diameters high indicated that vortex shedding induces an enhancement in both the mixing in the wake and the mass flux across the centreline of the wake. We also discuss our results in the context of prior works focussing on exploiting vortex shedding for enhancing thermal transport.
A Potential Role Exists for Nutritional Interventions in the Chronic Phase of Mild Traumatic Brain Injury, Concussion and Sports-Related Concussion: A Systematic Review

Mild traumatic brain injury (mTBI) represents a significant burden for individuals, economies, and healthcare systems worldwide. Recovery protocols focus on medication and physiotherapy-based interventions. Animal studies have shown that antioxidants, branched-chain amino acids and omega-3 fatty acids may improve neurophysiological outcomes after TBI. However, there appears to be a paucity of nutritional interventions in humans with chronic (≥1 month) symptomology post-mTBI. This systematic literature review aimed to consolidate evidence for nutrition and dietary-related interventions in humans with chronic mTBI. The review was registered with the International Prospective Register of Systematic Reviews (PROSPERO; CRD42021277780) and conducted following the Preferred Reporting for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Three reviewers searched five databases (PubMed/MEDLINE, Web of Science, SPORTDiscus, CINAHL Complete and Cochrane), which yielded 6164 studies. Nine studies met the inclusion criteria. The main finding was the lack of interventions conducted to date, and a quality assessment of the included studies was found to be fair to good. Due to heterogeneity, a meta-analysis was not feasible. The six nutrition areas identified (omega-3 fatty acids, melatonin, Enzogenol®, MLC901, ketogenic diet and phytocannabinoids) were safe and well-tolerated. It was found that these nutritional interventions may improve cognitive failures, sleep disturbances, anxiety, physical disability, systolic blood pressure volume and sport concussion assessment tool scores following mTBI. Potential areas of improvement identified for future studies included blinding, reporting compliance, and controlling for confounders. In conclusion, further research of higher quality is needed to investigate the role of nutrition in recovery from mTBI to reduce the burden of chronic outcomes following mTBI.
The role of low density lipoprotein receptor-related protein 11 as a tumor promoter in cervical cancer

Background: It is unclear whether low density lipoprotein receptor-related protein 11 (LRP11), a newly found lipoprotein receptor regulatory protein, has the carcinogenic effects in cervical cancer. Methods: Bioinformatics analysis, immunohistochemical (IHC) staining and evaluation, cell proliferation assay, ﬂ ow cytometry, transwell migration and invasion assays, Western blotting, growth of LRP11-silenced cells in athymic nude mice were performed in this research. Results: We found that LRP11 expression was higher in high-grade squamous intraepithelial lesions (HSIL) and cervical cancer tissue than in normal cervix, and high expression of LRP11 was associated with differentiation degree ( P =0.0266), indicating poor prognosis ( P =0.0210). The silencing of LRP11 in SiHa and CaSki cell lines inhibited cell proliferation, reduced migration and invasion and suppressed cell growth in nude mice, which possibly related to cell cycle protein regulation of CDK 2/4, cyclin D1/E1, MMP-2/9, and VEGF. Furthermore, LRP11 showed substantial positive correlation with P16 in vivo and in vitro. Conclusion: LRP11 plays important roles in proliferation, migration and invasion, with the potential to be a useful prognostic marker and therapeutic target for patients with HSIL and cervical cancer.
Fiber-orientation independent component of R2* obtained from single-orientation MRI measurements in simulations and a post-mortem human optic chiasm

The effective transverse relaxation rate (R2*) is sensitive to the microstructure of the human brain like the g-ratio which characterises the relative myelination of axons. However, the fibre-orientation dependence of R2* degrades its reproducibility and any microstructural derivative measure. To estimate its orientation-independent part (R2,iso*) from single multi-echo gradient-recalled-echo (meGRE) measurements at arbitrary orientations, a second-order polynomial in time model (hereafter M2) can be used. Its linear time-dependent parameter, β1, can be biophysically related to R2,iso* when neglecting the myelin water (MW) signal in the hollow cylinder fibre model (HCFM). Here, we examined the performance of M2 using experimental and simulated data with variable g-ratio and fibre dispersion. We found that the fitted β1 can estimate R2,iso* using meGRE with long maximum-echo time (TEmax ≈ 54 ms), but not accurately captures its microscopic dependence on the g-ratio (error 84%). We proposed a new heuristic expression for β1 that reduced the error to 12% for ex vivo compartmental R2 values. Using the new expression, we could estimate an MW fraction of 0.14 for fibres with negligible dispersion in a fixed human optic chiasm for the ex vivo compartmental R2 values but not for the in vivo values. M2 and the HCFM-based simulations failed to explain the measured R2*-orientation-dependence around the magic angle for a typical in vivo meGRE protocol (with TEmax ≈ 18 ms). In conclusion, further validation and the development of movement-robust in vivo meGRE protocols with TEmax ≈ 54 ms are required before M2 can be used to estimate R2,iso* in subjects.
Subfossil chironomid assemblages as paleoenvironmental indicators in lake faulersee (Germany)

Remains of chironomid larvae from cores of the ancient Lake Faulersee in northern Germany were examined. Pollen, radiocarbon datings, and geochemical data were used to develop the chronology of the Late-Glacial Period in Lake Faulersee and to validate interpretations made by chironomid data. Factors influencing the composition of the subfossil chironomid assemblages were assessed. Our data indicate fluctuations of temperature, lake-level, and trophic state in the Late-Glacial. Furthermore, we explain a discontinuous sequence found in the cores of Lake Faulersee pertaining to a refilling event about 5,800 cal years before present (BP).
Immune disorders induced by improper use of dietary immunostimulants in aquatic animals: Research progress and prospective solutions by targeting gut microbiota

Immunostimulants were widely used in aquafeed due to their multiple important functions, including promoting growth, enhancing non‐specific defence mechanisms and resisting infectious diseases. But the efficiencies of the positive effects of immunostimulants were affected by the duration of the administration and their dose. Short‐term and normal‐dose of immunostimulants promoted the growth and enhance non‐specific immunity of aquatic animals. However, improper use led to several immune disorders, including immune tolerance, immune exhaustion and over‐immunity. The application of two immunostimulant diets in rotation technique and the intermittent use of immune stimulant diets may solve the problems associated with immune disorders, but this application method will be limited by both species and immunostimulants. The occurrence of immune disorders is accompanied by different degrees of gut microbiota dysbiosis, especially significantly up‐regulated the abundance of Proteobacteria. Besides, the gut symbiotic microbiota plays a significant role in host immunity. Consequently, the regulation of gut microbiota may be an effective way to modulate immune disorders caused by improper use of polysaccharide immunostimulants. Regulating the gut microbiota not only solves the negative effects caused by improper use of immunostimulants without restrictions on both species and immunostimulants, but also has the advantage of simplicity and convenience compared to conventional approaches. In summary, this article reviews the possible negative effects caused by improper use of immunostimulants on aquatic animals and compares regular approaches with regulating gut microbiota. And gut microbiota maybe be used as a therapeutic target to improve immune disorders caused by immunostimulants in aquatic animals.
Steller Sea Lion Research and Coordination: A Brief History and Summary of Recent Progress

The Steller sea lion (Eumetopias jubatus), first listed under the Endangered Species Act (ESA) in 1990, has been the subject of intensive scientific research since a steep population decline was identified in the late 1980s. Research efforts during most of the 1990s were guided by recommendations contained in the Steller Sea Lion Recovery Plan. Research funding for federal agencies during this period was <$1 million (M) annually, of which over half was required for population monitoring surveys. During the late 1990s, Steller sea lion research activities were intensified as recent scientific findings, litigation, and new legislation focused increasing attention on the ongoing decline and concern over possible impacts by commercial fisheries in Alaskan waters. This renewed attention was manifest in a seven-fold increase in funding between 2000 and 2001, with over 125 individual projects planned or implemented. A wide spectrum of research entities were engaged in these studies, including federal and state agencies, universities and non-governmental research organizations. In cooperation with the entities that received federal funding, the National Marine Fisheries Service developed a research coordination framework to clarify the context of individual research projects, to show their relationships to each other and to link them to the underlying hypotheses that might explain the continued decline of Steller sea lions. This paper summarizes the evolution of Steller sea lion research over the past two decades and describes the development of a comprehensive and coordinated program that responds to Congressional intent.
Aerial Target Recognition With Enhanced Micro-Doppler Dynamic Features Based on Frequency-Modulated Continuous-Wave Radar

The micro-Doppler (m-D) signal generated by the micro-motion of aerial target can be extracted for recognition. However, the m-D signal is weak and prone to be interfered by the bulk Doppler (b-D) signal and environmental noise. Moreover, existing m-D handcrafted features are limited for aerial target classification. In this article, a novel aerial target recognition method based on enhanced m-D dynamic features is proposed. First, a singular spectrum analysis method based on turning point (TP-SSA) is applied to divide the signal into two subspaces with interference and noninterference. The b-D interference signal is separated by reconstructing the noninterference subspace. In addition, an empirical mode decomposition method based on chopping pulse matching (CPM-EMD) is adopted to select the components with high matching degree through a scoring function to reconstruct the m-D signal. Second, the m-D signal is decomposed by sliding windows. Eight handcrafted features are extracted for each short period to form a feature sequence set containing statistical and time-varying information. Finally, a bidirectional gated recurrent unit (BiGRU) network is used to further extract the dynamic features for aerial target classification. The experimental results show that the proposed robust method achieves higher recognition performance with lower parameters.
