Published: April 2023

The article presents the theoretical foundations of an innovation strategy as a means of increasing the level of competitiveness of an enterprise, as well as a description of a specific example of the positive use of an innovation strategy in an enterprise with a comprehensive analysis of the level of competitiveness and identification of the influence of the factor in the implementation of the innovation strategy.In the course of the study, both general scientific methods (analysis, synthesis, abstraction) and specific methods were used in the course of analyzing the level of competitiveness of an enterprise (matrix analysis, coefficient analysis, dynamic analysis, etc.). The results of the analysis showed a positive impact of the implementation of the innovation strategy on the level of competitiveness of the enterprise. The conclusions based on the results of the study will be useful in the course of the implementation of the strategic planning process and will improve the quality of the formation of an innovative strategy.
Evidence for extensile crack initiation in point source time-dependent moment tensor solutions
Authors: Baker Calum , Young R. Paul 
Published: April 2023

Abstract
A time-dependent moment tensor inversion technique is applied to 20 seismic events recorded ahead of an advancing tunnel excavation at the Underground Research Laboratory (URL) in Canada. The data are recorded on a 16-sensor triaxial accelerometer array, and the events are chosen from a section of the tunnel such that the event-sensor paths are unaffected by the presence of the tunnel. Factorization of the moment tensor rate functions for each event and subsequent decomposition of the subevents into isotropic and deviatoric components indicate that the events are of three types. The first group shows implosional/shear failure source mechanisms. These are associated with the observed collapse of excavation holes drilled at the side of the tunnel and provide confidence that the method is producing realistic results. The second group of events occurs in the region ahead of the face and show tensile/shear failure mechanisms. These are interpreted in terms of crack initiation ahead of the face and may explain why the tunnel undergoes notching and failure in the floor and roof when the modeled stresses are below the measured rock strength. The third group of events shows predominant shear failure throughout their rupture history. These are interpreted in terms of failure on pre-existing crack surfaces. This study highlights the value of using source mechanism studies of associated seismicity to understand the processes that may be taking place in environments where the stress field is complex both spatially and temporally.
Periodic seismicity near Mt. Ogden on the Alaska-British Columbia border: A case for hydrologically triggered earthquakes?
Authors: Wolf Lorraine W. , Rowe Charlotte A. , Horner Robert B. 
Published: April 2023

AbstractAn unusual series of seismic events has been observed routinely on networks operated by the Geological Survey of Canada in Sidney, British Columbia, and the Alaska Earthquake Information Center, Fairbanks, Alaska. Events are concentrated in a cluster near Mt. Ogden, about 50 km southeast of Juneau, and have a seasonal cycle of recurrence. A study of earthquake activity indicates that the annual cycle has two pulses, one beginning in May and increasing into June and July, and the second beginning in late August and increasing into October. Events are largely absent during winter months. In the 17-year period between 1975 and 1991, a cumulative total of 164 events with ML ∼ 3 has occurred in the month of October, contrasted with none in March or April.Epicenters for the events appear to lie near the Speel River, a northeast-southwest-oriented stream that drains glaciated areas of Mt. Ogden. Although the regional tectonic setting holds many candidates for seismic sources, including an active transform plate margin and recent volcanic activity, the periodic behavior of the cluster is not easily reconciled with these phenomena. In addition, the frequency of occurrence and magnitudes of the events are not consistent with patterns of glacier-generated seismicity. Examination of recent seismic activity yields a b-value of 1.0.Statistical comparisons of earthquake activity near Mt. Ogden with cycles of seasonal phenomena support a hydrologically related causal mechanism. These apparent correlations raise the possibility that the earthquakes are triggered either by transient changes in pore pressures due to the influx of meteoric water within faulted rock near Mt. Ogden or by increased pore pressures due to surface loading of glaciated areas.
A comparison of regional-phase amplitude ratio measurement techniques
Authors: Rodgers Arthur J. , Lay Thorne , Walter William R. , Mayeda Kevin M. 
Published: April 2023

Abstract
We compare several procedures for measuring regional-phase amplitude ratios commonly used in discrimination studies. Amplitude measurements are made on both raw velocity-proportional broadband seismograms and instrument-deconvolved displacement seismograms in the time and frequency domains. Pn/Lg and Pg/Lg ratios are measured on vertical-component waveforms for regional earthquakes observed at the Global Seismic Network (GSN) station ABKT (Alibek, Turkmenistan). Time-domain amplitude measurements are made on narrow-band filtered wave-forms using signal energy measures given by the absolute mean, rms, and envelope mean, and peak measures given by the absolute maximum and envelope maximum. Frequency-domain measurements are made by computing the log10-mean amplitude within a narrow band from the broadband spectrum of each windowed phase.
Time-domain amplitude ratios for raw velocity and instrument-deconvolved displacement seismograms are very similar (linear correlations ≧0.97), indicating that the instrument response does not affect the time-domain amplitude ratio measurements for the broadband GSN data at the frequencies studied (0.75 to 9.0 Hz). Time-domain amplitude ratios made using the energy or peak measures are well correlated among themselves (linear correlations ≧0.97). However, the energy and peak measures are slightly less well correlated with each other (linear correlations between 0.87 and 0.99). For the time-domain measures, the correlations generally degrade, and the scatter increases for the higher-frequency bands. Time- and frequency-domain measurements are well correlated for the lowest-frequency band (0.75 to 1.5 Hz). However, as the frequency band increases, the correlations decrease and the slopes deviate from 1.0. Time-domain amplitude ratios (for both Pn/Lg and Pg/Lg) are consistently larger than the frequency-domain amplitude ratios. Investigation of the frequency spectra of broadband and narrow-band filtered phases revealed that significant energy from outside the passband, particularly from lower frequencies, possibly biases the time-domain measurements. Log averaging the spectral amplitudes in a given passband before forming the amplitude ratios does not bias the measurements to the low end of passband. Better agreement between time- and frequency-domain measurements is found when linear averaging of the spectrum is used. These observations suggest that with care, time- and frequency-domain measures can be made to agree. We suggest that log-averaged frequency measures look promising for discriminant measures because (1) frequency-domain measurements offer complete control of the frequencies that contribute to the measurement, and (2) log averaging of the spectra does not overweigh spectral amplitudes associated with lower frequencies within the passband. However, because we consider only earthquake data, we cannot evaluate the discrimination performance of the various measurement techniques.
Stratigraphic and Paleoenvironmental Studies on the Lower Eocene Succession at El-Guss Abu Said Plateau, Farafra Oasis, Western Desert, Egypt

Published: April 2023

Abstract
The Lower Eocene Succession at El-Guss Abu Said Plateau was examined to determine the paleoenvironments and nature of deposition based upon benthic foraminiferal biofacies. Lithostratigraphically, this succession consists of the Esna Formation (shale) at the base, the Nusf Formation (well-bedded marl with occasional limestone ledges), and the Farafra Formation (limestone) at the top. The Esna Formation is an outer shelf-upper bathyal facies rich in planktonic and deeper-dwelling smaller benthic foraminifera. The Nusf Formation and the Farafra Formation are rich in Nummulites and Alveolinids, indicating a carbonate platform facies. Three benthic foraminiferal biofacies, combined with the lithology of the rock units, indicate progressive shoaling, likely associated with tectonic uplift that occurred during the early Eocene in the El-Guss Abu-Said area.
Multispecies Planktonic and Benthic Foraminiferal Stable Isotopes from North Atlantic Subtropical Site 558: Thermocline Intensification During the Mid-Miocene Climate Transition

Published: April 2023

AbstractWe reconstruct the subtropical North Atlantic water column structure during the Miocene Climate Optimum warming (MCO; 17–14.8 Ma) and the Middle Miocene Climate Transition cooling (MMCT; 14.8–12.8 Ma) by analyzing δ18O and δ13C in four species of foraminifera (surface dwellers Dentoglobigerina altispira and Trilobatus quadrilobatus, thermocline dweller Dentoglobigerina venezuelana, and benthic Planulina wuellerstorfi) from Site 558 (37.8°N). At the end of the MCO, δ18O of surface and thermocline dwellers increased by &gt;1‰, suggesting at least 2°C cooling in the upper ocean as ice growth increased global δ18Osw by ∼0.5‰. The difference in δ18O values between thermocline and surface-dwelling species increased during the MMCT, coinciding with the development of a largely permanent East Antarctic Ice Sheet, and persisted into the Late Miocene. We interpret this increase in vertical δ18O gradient as a strengthening of the thermocline due to intensification of subtropical gyre circulation in response to the MMCT cooling.

Inversion energy is parameter-against-gravity-internal-fluctuation, the non-simultaneousness gravitational tension among turnover fluctuations is quantizing time. Modified Newtonian Laws, first: 𝑑 𝑑𝑥 cosx =−𝑠𝑖𝑛𝑥, 𝑑 𝑑𝑥 sinx = 𝑐𝑜𝑠𝑥; second: 𝐹⃗ = 𝑚 ∙ 𝑎⃗ + |𝑚𝑔⃗ ∫ 𝑡𝑔𝜃 ⋅ 𝑑𝜃 ⟩ ↿⇂ third: Wavelength = 2 𝑛 , reeueenc = n𝑓0 . Bio-systems are topological spaces through repetitiveness memories to deliver a degenerated entropy for offspring, the trigonometric flux through the space by environmental surface inversion is bio-inertia. Schrödinger equation has only quantized energy thus inducing quantum collapse, we then utilize 𝑯̂ 𝜓 = 𝑬𝜓 + ∑ | cos( 1 𝑛 𝑛 𝑥)⟩ to degenerate eigenstates on a surface tension region to define G shifting quantum growth gravity for reconstructing non-simultaneous time. Originating from gravitational turnover tension between Planck regions and surface tension regions, bio quantum grows in vivo cross folded-surface tension region flow. By the Principle (or Law) of Entropy Degeneration, life relies on negentropy procurements to physically inherit by quantum growth turnover immunity that regenerates by sexual yolk sac (or asexual nucleus) homing. The evolution of long COVID niches and AI/BI is also unveiled.

Abstract
When soybean seeds encounter low temperature during germination, the vigor and germination of soybean seeds are affected, which leads to a lack of seedlings and weak seedlings, resulting in yield reduction. In-depth analysis of the genetic mechanism of soybean seed germination tolerance to low-temperature stress and the cultivation ofsoybean-tolerant varieties is the key to resisting low-temperature stress at the germination stage. In the present study, a chromosome segment substitution line (CSSL) population constructed by wild soybean ZYD00006 and cultivated soybean SN14 was used to map three QTLs. Five candidate genes were obtained by gene annotation, GO enrichment analysis and protein function prediction. The candidate genes were subjected to bioinformatics analysis, qRT-PCR analysis, trypsin activity analysis and soluble protein content analysis. The results showed that the secondary and tertiary structures of the Glyma.09G162700proteins were mutated. Within 0to 72 h, the expression of Glyma.09G162700 in the two materials with different toleranceswas consistent, and the change intrypsin activity was consistent with the change in protein expression. Through haplotype analysis, Glyma.09G162700 produced two haplotypes at -2420 bp. The germination rate (GR) and relative germination rate (RGR) of the two haplotypes were significantly different, indicating that the two haplotypes have wide applicability in soybean resources. In summary, Glyma.09G162700 may be a candidate gene for low-temperature tolerance at the germination stage of soybean. These results provide an important theoretical basis and marker information for analyzing the mechanism of low-temperature tolerance in soybean germination stage and cultivating low-temperature tolerant varieties.

Abstract
Faecal sludge (FS) or septage collected from an onsite containment system such as septic tanks, pit latrines, bio-digester etc., is handled in sewage treatment facilities with the help of a co-treatment unit or tackled individually at faecal sludge treatment plants (FSTPs). Treatment of faecal sludge in FSTPs is a generally cumbersome, energy-intensive, and expensive process. Enhancing the size of the solid particle, dewatering, and disinfection are essential unit operations that contribute to a significant portion of the operational expenditure. Therefore, the present study took up the task of investigating and yielding a natural alternative to each of the above-delineated unit operations. Crushed seed powders of Moringa, Guilandina bonduc, Nirmali, Tamarind, Soap nut, Nutmeg, Jackfruit, and Custard apple seed powder experimented as natural coagulants. At the same time, a double-stitched cow dung-lined jute tube was utilized as the media for solid-liquid separation. Finally, Neem and Custard Apple seed and leaf powder were considered herbal disinfectants for the separated liquid and solid fractions, respectively. The findings of the physicochemical and biological analysis of the above unit operations were compared with a conventional polymer-based Geotube driven treatment scheme. The natural alternatives registered some promising outcomes. However, the combined treatment efficacy of 78.94% for pollutant removal and disinfection could not exceed the value of 99.01% offered by the conventional method. Moreover, herbal alternatives are scarce, expensive, and slow reacting. Therefore, the authors recommend further research to overcome the persisting issues with herbal alternatives for their field-scale adaptation.

Published: April 2023

AbstractBackgroundThere is still paucity on the effects of dietary and supplemental fatty acid on non-alcoholic fatty liver disease (NAFLD). The aim of this review is to systematically review and summarise the effect of fatty acids intake on liver related outcomes in adult patients with NAFLD.MethodsThe review was conducted using Cochrane CENTRAL Library, scopus, Embase, MEDLINE, PubMed, and Web of Science. A total of 2786 records were identified, and of these, 36 studies (31 were randomised control trials (RCTs), and 5 were case-control studies) were included. Quality assessment was conducted using the Revised Cochrane Risk of Bias tool and Joanna Briggs Institute checklists.ResultsOf 36 articles, 79% of RCTs and 66% of case-control studies had a low risk of bias. Potential heterogeneity has been observed in assessment of liver related outcomes. According to the RCTs, there was moderate evidence (3/6 studies) that a diet characterised by a high MUFA, PUFA and low SFA showed reduced liver fat and stiffness. The using of culinary fats that are high in MUFA (4/6 studies) reduces liver steatosis. n-3 PUFA supplementation in combination with a hypocaloric or heart healthy diet with a low SFA improved liver enzyme level (5/14 studies) and steatosis score (3/14 studies).ConclusionsEffects on NAFLD parameters, including liver fat, stiffness and steatosis, were primarily related to fatty acid composition independent of energy intake. Further investigation is needed to determine the mechanism of specific fatty acid on the accumulation of liver fat.

Published: April 2023

Abstract
BACKGROUND The grading of oral epithelial dysplasia is often time-consuming for oral pathologists and the results are poorly reproducible between observers. In this study, we aimed to establish an objective, accurate and useful detection and grading system for oral epithelial dysplasia in the whole-slides of oral leukoplakia.
METHODSFour convolutional neural networks were compared using the image patches from 56 whole-slide of oral leukoplakia labeled by pathologists as the gold standard. Sequentially, feature detection models were trained, validated and tested with 1,000 image patches using the optimal network. Lastly, a comprehensive system named E-MOD-plus was established by combining feature detection models and a multiclass logistic model.
RESULTS EfficientNet-B0 was selected as the optimal network to build feature detection models. In the internal dataset of whole-slide images, the prediction accuracy of E-MOD-plus was 81.3% (95% confidence interval: 71.4% to 90.5%) and the area under the receiver operating characteristic curve was 0.793 (95% confidence interval: 0.650 to 0.925); in the external dataset of 229 tissue microarray images, the prediction accuracy was 86.5% (95% confidence interval: 82.4% to 90.0%) and the area under the receiver operating characteristic curve was 0.669 (95% confidence interval: 0.496 to 0.843).
CONCLUSIONSE-MOD-plus was objective and accurate in the detection of pathological features as well as the grading of oral epithelial dysplasia, and had potential to assist pathologists in clinical practice.
Diversity and composition of mixed-ploidy unisexual salamander assemblages reflect the key influence of host species

Abstract
Understanding processes that govern and sustain biological diversity is a central goal of community ecology. Unisexual complexes, where reproduction depends on sperm from males of one or more bisexual host species, are rare and the processes driving their diversity and structure remain poorly understood. Unisexual Ambystoma salamanders produce distinct biotypes (‘genomotypes’) depending on which bisexual species they ‘steal’ sperm from. This reproductive mode should generate distinct assemblages depending on the locally available bisexual host species. Yet, how availability and relative abundance of multiple bisexual hosts influences composition and diversity of natural unisexual assemblages at local or regional scales remains unknown. We hypothesize that host identity most directly drives local assemblage composition, with host variation associated with increased beta and gamma diversity within unisexuals. We collected genetic samples from Ambystoma salamanders across Pelee Island, Ontario, Canada (2015-2022). Two host species were identified (A. texanum and A. laterale) with nine sites having a single host and one site having both. Unisexual assemblages were grouped into four clusters by similarity, with host identity being a key determinant. Gamma diversity increased as a result of distinct host-specific assemblages forming at different sites on the island (i.e., high beta diversity). Assemblage composition, but not diversity, was correlated with relative host abundance, which may reflect matching niche requirements between host and unisexual forms they produce. Our results demonstrate that diversity and structure of unisexual assemblages are clearly shaped by their host(s) and such systems may serve as models for studying how biotic interactions shape ecological communities.
Commonly used indices completely disagree about the relative effect of moisture on heat stress

Published: April 2023

Abstract
Irrigation and urban greening can mitigate extreme temperatures and reduce adverse health impacts from heat. However, some recent studies suggest these interventions could actually exacerbate heat stress by increasing humidity. These studies use different heat stress indices (HSIs), hindering intercomparisons of the relative roles of temperature and humidity. Our novel method compares the sensitivity of HSIs to temperature and humidity, independent of HSI units. Using this method, we explain the properties of different HSIs and identify the conditions under which they agree or disagree. We highlight recent studies where the use of different HSIs could have led to opposite conclusions. Our findings have significant implications for the evaluation of irrigation and urban greening as adaptive responses to overheating, and climate adaptation measures in general. We urge researchers to be more critical in their choice of HSIs; our method provides a useful tool for making informed comparisons.
