Thermodynamics modeling of deep learning systems for a temperature based filter pruning technique

We analyse the dynamics of convolutional filters’ parameters of a convolutional neural networks during and after training, via a thermodynamic analogy which allows for a sound definition of temperature. We show that removing high temperature filters has a minor effect on the performance of the model, while removing low temperature filters influences majorly both accuracy and loss decay. This result could be exploited to implement a temperature-based pruning technique for the filters and to determine efficiently the crucial filters for an effective learning.
Energetic budget of diploid and triploid eastern oysters during a summer die-off

Triploid oysters are widely used in off-bottom aquaculture of eastern oysters, Crassostrea virginica. However, farmers of the Gulf of Mexico (GoM) and Atlantic coast estuaries have observed unresolved, late-spring die-offs of triploid oysters, threatening the sustainability of triploid aquaculture. To investigate this, the physiological processes underlying oyster growth (e.g., feeding, respiration) and mortality of one-year-old diploid and triploid oysters were compared in early summer following an uptick in mortality. It was predicted that higher triploid mortality was the result of energetic imbalances (increased metabolic demands and decreased feeding behavior). Oyster clearance rates, percentage of time valves were open, absorption efficiency, oxygen consumption rates (basal and routine), ammonia excretion rate were measured in the laboratory and scope for growth was calculated. In addition, their condition index, gametogenic stage, Perkinsus marinus infection level, and mortality were measured. Mortality of triploids in the laboratory was greater than for diploids, mirroring mortality observed in a related field study. The physiological parameters measured, however, could not explain triploid mortality. Scope for growth, condition index, and clearance rates of triploids were greater than for diploids, suggesting sufficient energy reserves, while all other measurements where similar between the ploidies. It remains to be determined whether mortality could be caused from disruption of energy homeostasis at the cellular level.
Functional deﬁcits in post-operative adolescent idiopathic scoliosis

BACKGROUND: Little or no research currently exists investigating musculoskeletal strength, joint ﬂexibility and cardiopulmonary capacity post-operative adolescent idiopathic scoliosis (AIS) patients. PURPOSE: ToexploreifAISpatientsfollowingspinalfusionsurgeryhavedeﬁcienciesinstrength,endurancejointﬂexibility and pulmonary capacity (>12-month post-operative) compared to a matched sample of the general population. METHODS: This retrospective case control study; AIS group ( n =20) and control group ( n =20) matched for gender, age and anthropometrics. Participants underwent standardised tests to establish pulmonary capacity via spirometry, upper and lower limb strength via manual muscle testing, upper and lower limb endurance via press-up and wall squat tests and joint ﬂexibility via manual goniometry. Within session reliability and reproducibility of variables were assessed. RESULTS: NosigniﬁcantdifferencesbetweenAISandcontrolcohortswereidentiﬁedformass(57.1 ± 9.0vs.62.8 ± 9.0kg), height (164.7 ± 6.3 vs. 165.6 ± 6.0cm) or BMI (21.2 ± 4.0 vs. 22.9 ± 2.7). Pulmonary and musculoskeletal deﬁciencies in the AIS cohort were identiﬁed, including signiﬁcantly lower forced vital capacity (FVC; 2.6 ± 0.5 vs. 3.3 ± 0.5L, P <0.001) and forced expiratory volume in 1 second (FEV 1 , 2.8 ± 0.6 vs. 3.3 ± 0.5L, P <0.001); restrictions in shoulder ﬂexion ( P <0.01) and internal rotation ( P <0.001) weaker bilateral pinch grip ( P <0.01) and bilateral hip adductor strength ( P <0.01). CONCLUSION: The results highlight that AIS patients still have major pulmonary and musculoskeletal impairments over a year after spinal fusion surgery. Clinicians should consider periodic assessment of pulmonary and musculoskeletal function with comparison to these age-matched reference values in order to improve the post-operative rehabilitation process.
Students’ and teachers’ digital competence in a Valencian network of cooperative schools

In the context of the increasingly digitalised modern society, the development of digital competence (DC) from early childhood is ever more essential. This situation represents a challenge for educational institutions at all levels, as they must ensure the development of students’ DC, as well as train staff in teachers’ digital competence (TDC). This study aims at measuring the self-perception of students’ DC and TDC in a network of primary and secondary schools in the Valencian Community as a first step toward the detection of possible gaps and inequalities that may need to be addressed. The results show a high level of self-perceived DC among students and a me-dium-expert level of TDC among teachers. Additionally, differences in the self-assessed level of DC and TDC were found between the scores for the individual dimensions and types of literacy that make up these competencies, and there were significant differences in teachers’ self-assessment as a function of age and educational level. These findings provide evidence for the need to develop training programs aimed at enhancing TDC in order to reduce the inequalities found.
THE ROTATIONAL EMISSION-LINE SPECTRUM OF ORION A BETWEEN 247 AND 263 GHZ

Results are presented from a molecular line survey of the core of the Orion molecular cloud between 247 and 263 GHz. The spectrum contains a total of 243 resolvable lines from 23 different chemical species. When combined with the earlier survey of Orion from 215 to 247 GHz by Sutton et al. (1985), the complete data set includes over 780 emission features from 29 distinct molecules. Of the 23 molecules detected in this survey, only NO, CCH, and HCO^+ were not identified in the lower frequency data. As a result of the supporting laboratory spectroscopy performed to supplement existing millimeter-wave spectral line catalogs, only 33 of the more than 780 lines remain unidentified, of which 16 occur in the upper frequency band. A significant chance remains that a number of these unidentified lines are due to transitions between states of either isotopically substituted or highly excited abundant and complex molecules such as CH_3OH, CH_3OCH_3, and HCOOCH_3, whose rotational spectra are poorly known at present. The very small percentage and weak strength of the unidentified lines implies that the dominant chemical constituents visible at millimeter wavelengths have been identified in the Orion molecular cloud.
Mechanisms of Lean on the Performance of Transonic Centrifugal Compressor Impellers

Transonic centrifugal compressors with high performance are required in modern gas turbine engines and turbochargers. Lean of the blades is one of the crucial features that have a significant influence on their performance. This paper numerically investigates mechanisms by which lean affects the performance of a transonic impeller with twin splitters. Lean is defined relative to the tangential direction, and the variation range of lean angle has been chosen from −5 to +5 deg. Results show that the variation of efficiency value is 4.5% and the optimal lean angle occurs near 0 deg. Lean influences the flowfields through the effects on the shock structure, the spanwise pressure gradient, the axial-to-radial flow separation, and the secondary flow structure. The induced second blade surface vortex with positive lean tends to migrate the low-momentum flow from hub to shroud, whereas the induced inward spanwise pressure gradient with negative lean enhances the axial-to-radial flow separation, both of which inc.
An Examination of the Lagrangian Length Scale in Plant Canopies using Field Measurements in an Analytical Lagrangian Equation

An examination of the Lagrangian length scale in plant canopies using field measurements in an analytical Lagrangian equation Shannon E. Brown University of Guelph, 2012 Advisor: Jon S. Warland Studies of trace gas fluxes have advanced the understanding of bulk interactions between the atmosphere and ecosystems. Micrometeorological instrumentation is currently unable to resolve vertical scalar sources and sinks within plant canopies. Inverted analytical Lagrangian equations provide a non-intrusive method to calculate source distributions. These equations are based on Taylor’s (1921) description of scalar dispersion, which requires a measure of the degree of correlation between turbulent motions, defined by the Lagrangian length scale (L). Inverse Lagrangian (IL) analyses can be unstable, and the uncertainty in L leads to uncertainty in source predictions. A review of the literature on studies using IL analysis with various scalars in a multitude of canopy types found that parameterizations where L reduces to zero at the ground produce better results in the IL analysis than those that increase closer to the ground, but no individual L parameterization gives better results than any other does. The review also found that the relationship between L and the measurable Eulerian length scale (LE) may be more complex in plant canopies than the linear scaling investigated in boundary layer flows. The magnitude and profile shape of L was investigated within a corn and a forest canopy using field measurements to constrain an analytical Lagrangian equation. Measurements of net CO2 flux, soil-to-atmosphere CO2 flux, and in-canopy profiles of CO2 concentrations provided the information required to solve for L in a global optimization algorithm for half hour intervals. For dates when the corn was a strong CO2 sink, and for the majority of dates for the forest, the optimization frequently located L profiles that follow a convex shape. A constrained optimization then smoothed the profile shape to a sigmoidal equation. Inputting the optimized L profiles in the forward and inverse Lagrangian equations leads to strong correlations between measured and calculated concentrations (corn canopy: Ccalc = 1.00Cmeas + 52.41 μmol m−3, r = 0.996; forest canopy: Ccalc = 0.98Cmeas + 276.5 μmol m−3, r = 0.99) and fluxes (corn canopy: Fsoil = 0.67Fcalc − 0.12 μmol m−2s−1, r = 0.71, Fnet = 1.17Fcalc + 1.97 μmol m−2s−1, r = 0.85; forest canopy: Fsoil = 0.72Fcalc − 1.92 μmol m−2s−1, r = 0.18, Fnet = 1.24Fcalc+0.65 μmol m−2s−1, r = 0.88). In the corn canopy, coefficients of the sigmoidal equation were specific to each half hour and did not scale with any measured variable. Coefficients of the optimized L equation in the forest canopy scaled weakly with variables related to the stability above the canopy. Plausible L profiles for both canopies were associated with negative bulk Richardson number values.

Numerical Solution of the Hamilton – Jacobi – Bellman Formulation for Continuous-Time Mean – Variance Asset Allocation Under Stochastic Volatility

We present efficient partial differential equation (PDE) methods for continuous-time mean-variance portfolio allocation problems when the underlying risky asset follows a stochastic volatility process. The standard formulation for mean-variance optimal portfolio allocation problems gives rise to a two-dimensional nonlinear Hamilton-Jacobi-Bellman (HJB) PDE. We use a wide stencil method based on a local coordinate rotation to construct a monotone scheme. Further, by using a semi-Lagrangian times stepping method to discretize the drift term, along with an improved linear interpolation method, accurate efficient frontiers are constructed. This scheme can be shown to be convergent to the viscosity solution of the HJB equation, and the correctness of the proposed numerical framework is verified by numerical examples. We also discuss the effects on the efficient frontier of the stochastic volatility model parameters.
Vector Valued Siegel Modular Forms of Symmetric Tensor Weight of Small Degrees

In this paper, we give explicit generators of the module given by the direct sum over k of vector valued Siegel modular forms of degree two of level 1 of weight det Sym(j) for j = 2, 4, 6. The results have been announced in [12] and [13] and also a version of preprint was quoted in [7], but this is the first version containing precise proofs. Vector valued Siegel modular forms seem to attract more attention nowadays in many respects, like in Harder’s conjecture, cohomology of local systems, or in some liftings or lifting conjectures (cf. [10], [7], [21], [14], [17] for example), and it seems worthwhile to publish these results now. More precise contents are as follows. We denote by Ak,j (Γ2) the linear space of Siegel modular forms of degree two of weight det Sym(j) where Sym(j) is the symmetric tensor representation of degree j and Γ2 is the full Siegel modular group of degree two. When j = 0, this is nothing but the space of scalar valued Siegel modular forms and we write Ak,0(Γ2) = Ak(Γ2). We define A sym(j)(Γ2) = ⊕ k:even Ak,j (Γ2) and A sym(j)(Γ2) = ⊕ k:odd Ak,j (Γ2). When j = 0, we write A(Γ2) = A sym(0)(Γ2). Then obviously A sym(j)(Γ2) or A odd sym(j)(Γ2) is an A (Γ2) module. T. Satoh gave the structure of A sym(2)(Γ2) as an A (Γ2) module in [22]. A rough content of our main theorem is as follows.
Enthalpy Transfer across the Air–Water Interface in High Winds Including Spray

AbstractControlled experiments were conducted in the Air–Sea Interaction Saltwater Tank (ASIST) at the University of Miami to investigate air–sea moist enthalpy transfer rates under various wind speeds (range of 0.6–39 m s−1 scaled to equivalent 10-m neutral winds) and water–air temperature differences (range of 1.3°–9.2°C). An indirect calorimetric (heat content budget) measurement technique yielded accurate determinations of moist enthalpy flux over the full range of wind speeds. These winds included conditions with significant spray generation, the concentrations of which were of the same order as field observations. The moist enthalpy exchange coefficient so measured included a contribution from cooled reentrant spray and therefore serves as an upper limit for the interfacial transfer of enthalpy. An unknown quantity of spray was also observed to exit the tank without evaporating. By invoking an air volume enthalpy budget it was determined that the potential contribution of this exiting spray over an .
Supportive Care for Patients With Myelodysplastic Syndromes

Abstract Myelodysplastic syndromes are a heterogeneous group of bone marrow disorders characterized by ineffective hematopoiesis, progressive cytopenias, and an innate capability of progressing to acute myeloid leukemia. The most common causes of morbidity and mortality are complications related to myelodysplastic syndromes rather than progression to acute myeloid leukemia. Although supportive care measures are applicable to all patients with myelodysplastic syndromes, they are especially essential in patients with lower-risk disease who have a better prognosis compared with their higher-risk counterparts and require longer-term monitoring of disease and treatment-related complications. In this review, we will address the most frequent complications and supportive care interventions used in patients with myelodysplastic syndromes, including transfusion support, management of iron overload, antimicrobial prophylaxis, important considerations in the era of COVID-19 (coronavirus infectious disease 2019), role of routine immunizations, and palliative care in the myelodysplastic syndrome population.
A Systematic Review and Meta-analysis of Clinical Outcomes in Autologous Breast Reconstruction Using Internal Mammary Artery Perforators as Recipient Vessels

Background: Recipient vessel selection is vital for successful autologous free-flap breast reconstruction. Internal mammary artery perforators have gained interest as a recipient vessel option. However, previous studies on their microsurgical safety and efficacy are limited and inconsistent. Thus, we conducted a systematic review and meta-analysis to assess the safety and effectiveness of using internal mammary artery perforators as recipient vessels in breast reconstruction. Methods: The protocol has been previously published in PROSPERO (CRD42020190020). The PubMed, Scopus, Web of Science, and PROSPERO databases were searched. Two independent reviewers evaluated the articles for inclusion in the study. Study quality was assessed using the Newcastle-Ottawa Scale and the MINORS instrument (Methodological Index for Non-Randomized Studies). Results: Of the 361 articles screened, 13 studies were included (313 patients with 318 flaps; 223 unilateral, 31 bilateral, mean average age 51.2 and mean BMI 27.8 ± 1.9). The mean overall success rate was 99.8%, the pooled surgical success rate was 100% [95% confidence interval (CI): 97%–100%], and the overall rate of complications was 11% (95% CI: 7%–18%). The most common complication was vascular-related to microanastomoses, with an incidence of 5% (95% CI: 2%–10%). The fat necrosis rate was 3% (95% CI: 2%–6%). Conclusions: This study verified that internal mammary artery perforator vessels are reliable in breast reconstruction, with a high success rate and a relatively low complication rate. Moreover, in selected microsurgical breast reconstruction patients, internal mammary artery perforators may be the primary recipient vessel choice over the internal mammary artery or thoracodorsal vessels.
Analysis on Affect Recognition Methods in the Wild

Affect recognition transition from laboratory-controlled to challenging in the wild conditions is an intense area of research, with a potentially long list of important application. Audio-visual modalities are significant contributors that provide rich contextual information from real world challenging corpora. These modalities can be explored for better discrimination of real world human emotions that are complex and compound. A comprehensive literature survey is carried out to identify the most relevant big databases and the way features are extracted and fused from visual and auditory data. The main focus is on recent state of Art research work using real-world corpora and the work comparing designed framework on controlled as well as in the wild data.
Improvements in Typhoon Intensity Change Classification by Incorporating an Ocean Coupling Potential Intensity Index into Decision Trees

AbstractTropical cyclone (TC) intensity prediction, especially in the warning time frame of 24–48 h and for the prediction of rapid intensification (RI), remains a major operational challenge. Sea surface temperature (SST) based empirical or theoretical maximum potential intensity (MPI) is the most important predictor in statistical intensity prediction schemes and rules derived by data mining techniques. Since the underlying SSTs during TCs usually cannot be observed well by satellites because of rain contamination and cannot be produced on a timely basis for operational statistical prediction, an ocean coupling potential intensity index (OC_PI), which is calculated based on pre-TC averaged ocean temperatures from the surface down to 100 m, is demonstrated to be important in building the decision tree for the classification of 24-h TC intensity change ΔV24, that is, RI (ΔV24 ≥ 25 kt, where 1 kt = 0.51 m s−1) and non-RI (ΔV24 < 25 kt). Cross validations using 2000–10 data and independent verification usin.
Biocompatibility of different resin composites after polymerization with two light curing units: an immunohistochemical study

Purpose: The aim of this study is to compare the biocompatibility of two different resin composites after polymerization under two different light sources in three different time periods. Materials and methods: 72 polyethylene tubes polymerized with 2 different resin composites and 2 different light sources (Elipar S10 and Valo ) [Group 1: Kalore Elipar S10 (KE), Group 2: Kalore Valo (KV), Group 3: Essentia Elipar S10 (EE), Group 4: Essentia Valo (EV)] were implanted in the dorsal connective tissue of 18 rats. 24 empty polyethylene tubes [Group 5: (Control group)] were implanted in the dorsal connective tissue of 6 rats. Then, the rats were sacrificed after 7th, 15th and 30th days in each time intervals (n=8). Biopsy samples were stained with H&E and examined for inflammation, necrosis, macrophage infiltrate, giant cell and fibrous capsule criteria. Immunohistochemical staining was performed to evaluate proinflammatory cytokines (IL-1β, IL-6 and IL-8). Results: When the composite groups and the control groups were compared; the difference was statistically significant for the criteria of inflammation at 7th and 15th days, there was no statistical difference between the time points in terms of fibrous capsule and necrosis. When the composite groups and control groups were evaluated in terms of proinflammatory cytokines; statistically significant differences were found at 7th, 15th and 30th days. Conclusion: All CRs used in this study showed acceptable biocompatibility in the subcutaneous tissues of rats after polymerization with different light sources.
Inland penetration of sea‐breeze fronts

The advance inland of the sea-breeze past Lasham, 45 km from the south coast of England, has been measured over a period of twelve years. In this time 76 sea-breeze fronts passed Lasham, 36 passed Reading and 12 reached Harwell, 85km from the coast. the rate of advance from Lasham to Harwell in calm or light offshore winds was close to 3 ms−1, and the latter station was passed after sunset at a mean time of 2105 GMT. With onshore winds fronts only appear 30 or 40 km inland, and some fronts may be modified by effects due to the east coast. In some cases detailed measurements were made using pilot balloons, an instrumented motor-glider and radar. the fronts were shown to have raised heads about twice the depth of the following flow and within the heads dry patches occur. Variable secondary flows are inferred and comparison with water-tank models shows that several dynamical features in the tank and in the atmosphere are similar. Measurements support the picture of the development of the front during the day as a gravity current, and theoretical rates of advance are deduced. the observed acceleration of the front in the late afternoon is explained in terms of the increased temperature contrast at the front due to the decrease in solar heating of the sea-air. Shortly before sunset, a sea-breeze vortex may be detached from the rest of the flow. In a case study, it is shown that friction at the upper surface is at least five times that at the ground, and heat and humidity budgets are given for the detached vortex.
