Quantum Gravity Emergence from Entanglement in a Multi-Fold Universe

We start from a hypothetical multi-fold universe U_{MF}}, where the propagation of everything is slower or equal to the speed of light and where entanglement extends the set of paths available to Path Integrals. This multi-fold mechanism enables EPR (Einstein-Podolsky-Rosen) “spooky actions at distance” to result from local interactions in the resulting folds. It produces gravity-like attractive effective potentials in the spacetime, between entangled entities, that are caused by the curvature of the folds. When quantized, multi-folds correspond to gravitons and they are enablers of EPR entanglement. Gravity emerges non-perturbative and covariant from EPR entanglement between virtual particles surrounding an entity.In U_{MF}, we encounter mechanisms that predict gravity fluctuations when entanglement is present, including in macroscopic entanglements. Besides providing a new perspective on quantum gravity, when added to the Standard Model and Standard Cosmology, U_{MF} can contribute explanations of several open questions and challenges. It also clarifies some relationships and challenges met by other quantum gravity models and Theories of Everything. It leads to suggestions for these works.We also reconstruct the spacetime of U_{MF}, starting from the random walks of particles in an early spacetime. U_{MF} now appears as a noncommutative, discrete, yet Lorentz symmetric, spacetime that behaves roughly 2-Dimensional at Planck scales, when it is a graph of microscopic Planck size black holes on a random walk fractal structure left by particles that can also appear as also microscopic black holes. Of course, at larger scales, spacetime appears 4-D, where we are able to explain curvature and recover Einstein’s General Relativity. We also discover an entanglement gravity-like contributions and massive gravity at very small scales. This is remarkable considering that no Hilbert Einstein action, or variations expressing area invariance, were introduced. Our model also explains why semi classical approaches can work till way smaller scale than usually expected and present a new view on an Ultimate Unification of all forces, at very small scales.We also explore opportunities for falsifiability and validation of our model, as well as ideas for futuristic applications that may be worth considering, if U_{MF} was a suitable model for our universe U_{real}.

Tecnoestrés en población mexicana y su relación con variables sociodemográficas y laborales

Objective: To measure the relationship between sociodemographic variables, labor variables, andtechnology frequency of use with the level of technostress experiences such as techno-anxiety,techno-fatigue, and techno-addiction, using a sample of Mexican adolescents, youth, and adults. Method: The participants of the study were 981 Mexican nationals aged 13–69. The scales implementedto measure technostress and techno-addiction were the ones used in Cazares & Villavicencio (2019)and a sociodemographic and labor variables questionnaire created by the authors, implemented usingGoogle’s form tool. Data obtained were subjected to a descriptive, correlational, and inferential levelanalysis (Kerlinger & Lee, 2002), using the statistical software SPSS v.20. Results: Regarding techno-fatigue, the results showed significant differences on the basis of sex (U= 104026.50, p = 0.037) and seniority [χ2(3) = 11.213, p = 0.011] and a marginal significance on thebasis of marital status (U = 78329.00, p = .058). Regarding techno-addiction, significant differenceswere found on the basis of marital status (U = 76121.50, p = 0.012) and occupation [χ2(2) = 4.698, p =0.008]. Regarding techno-anxiety, significant differences were found on the basis of company type (U =61348.00, p = 0.049). Finally, it was found that people who received better schooling, such as directors and independent entrepreneurs, showed greater techno-anxiety, techno-fatigue, and techno-addiction. Conclusions: The results confirm that technostress is prevalent in Mexico. In addition, there is a confirmedrelationship between technostress experiences, sociodemographic variables (sex, marital status,occupation, and schooling), and labor variables (seniority, company type, and position level). The resultsconstitute the first technostress research contributions in Mexico, a country that encourages the use oftechnology.
Graph Wavelet Long Short-Term Memory Neural Network: A Novel Spatial-Temporal Network for Traffic Prediction

Timely accurate traffic prediction is important in the Intelligent Traffic System (ITS). It has time-varying traffic patterns and the complicated spatial dependencies on traffic network topology which makes the prediction challenging. In this paper, we propose a novel deep learning framework—Graph Wavelet Long Short-Term Memory Neural Network (GWNN-LSTM) to capture the spatial and temporal dependence simultaneously. Moreover, Graph Wavelet Neural Network (GWNN) is utilized for spatial correlations and Long Short-Term Memory Neural Network (LSTM) is used to capture the dynamic temporal correlations in traffic time series data. Experiments on real-world datasets from loop detectors in the highway of Los Angeles County (METR-LA) demonstrate that the proposed GWNN-LSTM model outperforms the state-of-the-art baselines.
Microphone Array and Raspberry Pi Interfacing for Real-time DOA Estimation and Tracking of Audio Sources

Microphone arrays are commonly used for Direction of Arrival (DOA) estimation of audio sources. This paper presents the design and implementation of a real-time embedded system (RTES) for audio source localization. A commercially available microphone array assembly (consisting of four microphones) has been interfaced to Raspberry Pi 3B for estimating the arrival angles of audio/sound/acoustic sources. The acoustic signals received a teach of the microphones are used for DOA estimation using the Generalized Cross Correlation Phase Transform (GCC-PHAT) algorithm. The estimated DOA is then displayed on the serial monitor. Servo motors are interfaced to the Raspberry Pi and are programmed to point towards the estimated direction of the audio source (on the basis of the estimated DOA value). The estimated DOA value is also updated to the cloud-based server Firebase using the inbuilt Wi-Fi on Raspberry Pi, and can be remotely accessed through a smartphone running on android platform. The proposed system has been designed and tested successfully and it is observed that it provides accurate DOA estimation and audio source tracking in real-time. This has various uses in applications like voice assistant robots
Long-term trends and impacts of polar cold airmass in boreal summer

The northern polar region possesses the most extensive cold airmass on Northern Hemisphere. The generation of this polar cold airmass and its outflow to lower latitudes play an important role in the climate system in terms of mass and heat exchanges. However, long-term changes in the polar cold airmass, especially in summer, and the climatic effects on mid-high latitudes are still unclear. Using an isentropic approach, we quantitatively show that the polar cold airmass amount has decreased rapidly since the 1980s, with a decade lagging behind the global warming. The equatorward flux of the cold airmass has also weakened, trapping the cold airmass in its source region. These profound changes in the cold airmass coincide with a period characterized by rapid surface warming and increasingly frequent heat waves in recent three decades over the mid-high latitude continents. Owing to regional differences in the cold airmass reduction, Europe and North America have experienced a surface warming faster than the Northern Hemisphere mean. Furthermore, such a long-term trend in the polar cold airmass can be attributed to Arctic sea ice loss and internal decadal variability of sea surface temperature in high-latitude oceans. Our results highlight that the isentropic analysis of cold airmass may serve a good detection of the climate change at polar region and mid-high latitudes.
Urban Agriculture: Determinants and Its Implication on Poverty Reduction: A Case of Bishan Guracha Town, West Arsi Zone, Oromia Regional State, Ethiopia

The main intention of this study is to analyze the determinants of urban agriculture and its implication on poverty reduction. To this end, convergent parallel mixed design was utilized. All individuals working on the three urban agricultures were comprised of the study population. Specifically, 228 participates were participated on the research of which 118, 53 and 52 households were selected from fishery, milk and animal fattening micro and small enterprises respectively. Study participants were selected via employing stratified random sampling method proportionally. Further, key informants were taken purposefully for the intent of qualitative data. Questionnaire, semi-structured interview and focus group discussion guides were used as tools of data collection method. To categorize the status of poverty as poor and non-poor Foster, Greer and Thorbecke (FGT) index was used. Whereas one-way ANOVA was computed to identify whether statistically significant differences among the income generated from the three types of urban agricultures or not. Binary logistic regression was employed to pinpoint the determinants of urban agricultures while qualitative data was analyzed thematically. The finding suggested that about 40% of urban agricultural practitioners are failed blow poverty line. The results revealed that there were statistically significant differences among the three types of urban agricultures by the income earned from it. Inexplicably, modern fish net, access to different credit services, shortage of local boat, conflict of interest and access to saving and sex, education level, market fluctuation, lack of veterinary institution, lack of attention to the sectors, lack of extension services, lack of training and shortage of access to transportation were found to be determinants of fishery. Extension service, access to market linkage, shortage of input and climate changes and lack of market linkage, improved livestock, shortage of land and access to transport were not found to be statistically significant association with the income of households who have been taking part on animal Fattening productions in the study area.

This study was performed to improve antioxidant activities and skin-whitening effects of Rubus coreanus Miquel extracts by nano-encapsulation. R. coreanus was extracted at and encapsulated by lecithin and gelagine. Nano-encapsulated extracts showed highest free radical scavengering effect as 97.62% in adding sample (), compared to the extracts from conventional processes. It was showed strong inhibition effect on melanin production test by Clone M-3 cells as 55.23%. High inhibitory potency on tyrosinase was also measured as 155.8% by adding nano-sample of 1 . The improvement of biological activity was demonstrated by real time confocal microscope. We could consider that the water soluble extracts of R. coreanus could be definitely enhanced by nano-encapsulated as a potent natural resources for antioxidant and skin-whitening agent.
Inodilator versus inotrope: do inodilators have an edge to improve outcome in patients with heart failure or cardiac dysfunction?

Numerous meta-analyses on inotropes (dobutamine) and inodilators (milrinone, levosimendan) suggest that their impact on survival are at best neutral (but may be deleterious) whereas levosimendan seems to have beneficial effects on survival in patients with acute heart failure (AHF) syndromes. The aim of this essay is to attempt to explain these results through a conceptual framework of cardiocirculatory (patho)physiology. Many clinical studies in AHF have been based and interpreted on a ‘cardiocentric’ framework. The three above-mentioned categories of drugs are thought to increase cardiac output (CO) by increasing only heart muscle contraction (inotropes) or by also decreasing systemic vascular resistance (inodilators). We complement this ‘cardiocentric’ framework with a more integrated one based on (i) the effects of drugs on venous return (VR), equal to CO (VR is the difference between mean systemic and right atrial pressures divided by venous resistance; maintenance of adequate VR depends on the stressed blood volume); inodilators may decrease the stressed volume and therefore may decrease VR; (ii) the coupling of the left ventricle–aorta and right ventricle–pulmonary artery (dependent on the compliance of the large arteries), which is increased by inodilators in the absence of measurable effects on arterial systemic/pulmonary pressures) and (iii) the vascular waterfall phenomenon, which explains that inodilators, by decreasing intra-organ arterial resistance, can improve organ perfusion even in previously mildly hypotensive patients (in the absence of cardiogenic shock). The challenge is to transform these concepts into clinical tools to guide therapy in AHF syndromes.
Lipid profile in an urban healthy adult Bangladeshi population

Background and objectives: The prevalence of ischemic heart disease (IHD) has increased in most of the developing countries, including Bangladesh. An important marker of IHD is dyslipidemia which includes high levels of triglyceride (TG), total cholesterol (T-cholesterol), low density lipoprotein cholesterol (LDL-c) and low level of high density lipoprotein cholesterol (HDL-c). So it is very important to know the lipid levels of a particular population for early intervention and prevention of IHD. The present study investigated the lipid levels of healthy urban adult Bangladeshi population. Methods: The cross sectional study was carried out over a period of one year at the Department of Physiology of Ibrahim Medical College, Dhaka, Bangladesh. A total number of 286 apparently healthy individuals were included in this study. Blood sample following overnight fast was collected for determination of serum TG, T-cholesterol, LDL-c and HDL-c. For all four lipid components, 95th percentile value was calculated and compared with values recommended by World Health Organization (WHO). Results: A total number of 286 adult individuals were enrolled of which 130 (45.5%) and 156 (54.5%) were male and female respectively. The mean levels of TG (122±56 mg/dl) and T-cholesterol (178±25 mg/dl) of male participants were significantly (p=0.001, p=0.008) higher than that of females (79.3±35.6 and 170±26 mg/dl). The level of serum HDL-c was significantly (p=0.001) higher in females (46.1±7.8 mg/dl)) compared to the males (39.7±8.6 mg/dl). The 95th percentile values of TG, T-cholesterol and LDL-c were higher than that of values recommended by WHO. Of the total participants, 17.1% to 24.1% had TG, T-cholesterol and LDL-c levels higher than the WHO recommended range. Conclusion: It is concluded that a proportion of our urban healthy young adult population had lipid profiles different from that recommended by WHO. Ibrahim Med. Coll. J. 2020; 14(1): 13-17
Comparison Study between Fraunhofer and Fresnel Diffraction in Case of Coherent and Incoherent Illumination

In this paper, the effect of Coherent and Incoherent illumination in case of Fraunhofer and Fresnel diffraction have been studied. The comparison has been studied qualitatively in terms of Point Spread Function "PSF" and Modulation Transfer Function "MTF". This study assumed that there is no aberration and the medium is homogenous i.e.no turbulence. The results show that imaging in case of Fraunhofer diffraction pattern is better than imaging in case of Fresnel diffraction pattern, and for the two type of illumination. Moreover, imaging using incoherent illumination is better than imaging using coherent illumination, and for the two types of diffraction pattern

Measurements of Carbon Dioxide Fluxes by Chamber Method at the Rzecin Wetland Ecosystem, Poland

The assessment of net ecosystem exchange (NEE) and respiration of ecosystem (Reco) of terrestrial ecosystems is necessary to improve our knowledge about the carbon cycle. The aims of this paper were to present reliable measurements of CO2 fluxes of a temperate bog ecosystem located in Poland using a closed dynamic chamber system and to obtain a daily dynamic course of CO2 fluxes over the 2007 vegetation season. Measurements of CO2 fluxes were carried out at Rzecin peatland ecosystem located in northwestern Poland using the set of two chambers (dark and transparent). Reco during the experiment period ranged from 2.65 to 14.76 µmolCO2·m -2 ·s -1 . The daily run of NEE was inversed to PPFD and the values of NEE varied from 0.06 to -11.82 µmolCO2·m -2 ·s -1 . We found differences between NEE and Reco in the wetland ecosystem with respect to term of measurements. The PPFD, air and soil temperatures explain most temporal variability of CO2 fluxes at Rzecin. But vegetation structure, its phenology and water-level depth seem also to play important roles. The chamber technique is a useful tool for determining carbon dioxide exchange between wetland surface and the atmosphere.
Fracaso de la reconstrucción del ligamento cruzado anterior. Revisión de la literatura

La cirugía reconstructiva del ligamento cruzado anterior (LCA) mediante técnicas artroscópicas ha experimentado un rápido crecimiento en las últimas décadas, constituyendo un significativo porcentaje del total de las intervenciones ortopédicas. La tendencia actual promueve el uso de abordajes poco invasivos, con la máxima preservación anatómica, ambulatorios en muchas ocasiones y, consecuentemente, con una más rápida rehabilitación. Todo ello supone un aumento en la expectativa de recuperación por parte del paciente que demanda resultados. Sin embargo, la cirugía de reconstrucción del LCA, como cualquier otra técnica quirúrgica, no está exenta de resultados insatisfactorios. Proponemos una revisión bibliográfica sobre los diferentes parámetros a valorar en el concepto de “fracaso de la cirugía de reconstrucción del LCA” y añadimos comentarios bibliográficos y técnicos para su manejo y resolución.
DRY SLIDING WEAR AND SURFACE MORPHOLOGICAL EXAMINATION OF AN ALUMINIUM MATRIX COMPOSITE REINFORCED WITH PALM KERNEL SHELL

The wear resistance and microstructural features of aluminum AA6063 based composites reinforced with seven different mass fractions of palm kernel shell particles (0, 2.5, 5, 7.5, 10, 12.5 & 15wt%) fabricated by stir-casting, were characterized using pin-on-disk tribometer, optical microscope, and ImageJ package. ImageJ particle analysis revealed both the particle size and shape descriptors for the composites' microstructural features. The average grain sizes of all the composites were higher than that of the unreinforced AA6063 matrix. Wear tests conducted under dry sliding condition show that the volume reduction and specific wear rate increased to a maximum at 5wt% PKS addition and then decreased to the lowest level at 10wt% PKS. Subsequent addition of PKS above 10wt% yielded a further increase in the composites volume loss and specific wear rate. Composite sample reinforced with 10wt% PKS exhibited wear resistance response better than that of the unreinforced alloy. Image analysis afforded a comprehensive understanding of the microstructural features of the composites which influenced their behaviors.
Variable step size fractional incremental conductance for MPPT under changing atmospheric conditions

This paper presents a new modified variable step size Fractional Order Incremental Conductance (FOIC) with maximum power point tracking using Fractional Order PID controller tuned by bio‐inspired Particle Swarm Optimization (PSO) to find optimal gain values of fractional integrator order (λ) and fractional derivative order (μ). The classical incremental conductance and FOIC show drawbacks under changing irradiance, oscillation around maximum power point (MPP) which decreases its convergence speed. To resolve these prone a variable step size FOIC is proposed to achieve an adaptive duty cycle via tuning of FOPID through PSO. The robustness of the proposed technique is judged by its steady‐state and dynamic response with fast converges, less response time, overshoot, and ripples under changing environmental conditions. Furthermore, the performance of the proposed technique is evaluated by comparing it with a fixed step size conventional incremental conductance algorithm and FOIC.
Sounding the Arctic in Chantal Bilodeau’s Climate Change Plays

Quebec-born playwright Chantal Bilodeau has been responding to the challenges of dramatizing anthropogenic climate change by developing an eight-part Arctic Cycle, each play of which is set in one of the nations that claims Arctic territory. Sila (2014) immerses audiences into a complex network of humans, animals, and mythical beings crisscrossing the Canadian Arctic. These movements circle around the Inuit concept of sila, which is the life-giving force of breath and voice. Thus, the sonic world of Sila focuses on voices speaking words, on performance poetry, and on the sounds of breath and wind. Bilodeau’ s second Arctic Cycle play, Forward (2016), addresses the long-term impact of Fridtjof Nansen’s polar exploration of the 1890s on Norway’s economy and society. In terms of sound, Forward features multiple musical performances rangingfrom traditional songs to European opera arias and Lieder to contemporary Norwegian electro-pop. The sonic features of both plays stress interdependence across time, space, as well as (non-)human, earthly, and metaphysical realms. Sila and Forward address climate change in a non-universalizing manner which promotes a heterarchical (rather than hierarchical) aesthetic fit for a growing awareness of planetary relationality.
Energy and Macronutrient Considerations for Young Athletes

41 Young athletes undergo many anatomical and physiological changes during the first two 42 decades of life as a result of growth and maturation. Such changes influence a young 43 athlete’s nutritional requirements and it is therefore inappropriate to apply nutritional 44 guidelines for adult athletes to this population. Nutritional recommendations for young 45 athletes should not only focus on sporting performance but should also meet the 46 requirements to ensure optimal growth, maturation and physical development. This review 47
