Non-Boolean hidden variable model reproduces Quantum Mechanics’ predictions for Bell’s experiment.
Authors: Hnilo Alejandro 
Published: August 2022

Abstract
The experimentally verified violation of Bell’s inequalities apparently implies that at least one of two beliefs, which are accepted as true in almost all scientific practice, must be false. These beliefs are: that effects propagating at infinite velocity do not exist, and that natural phenomena occur independently of being observed. Giving up any one of these two beliefs (usually known together as Local Realism) is controversial. For many years, many theories have been proposed to reconcile the violation of Bell’s inequalities with Local Realism, but none has been fully successful. In this paper, it is recalled that Bell’s inequalities are equivalent to the conditions to decide the completeness of a theory according to Boolean logic. Therefore, any theory aimed to violate Bell’s inequalities must start by giving up Boolean logic. Two problems are therefore defined: the “soft” one is to explain the violation of Bell’s inequalities without violating (non-Boolean) Local Realism; the “hard” one is to predict the time values when single particles are detected, in such a way that the resulting number of coincidences violates Bell’s inequalities. A simple hidden variables model is introduced, which solves the “soft” problem even in an ideal setup. This is possible thanks to the use of vectors in real space as the hidden variables and the corresponding operation (projection), which do not hold to Boolean logic. This model reconciles the violation of Bell’s inequalities with Local Realism and should end a controversy that has lasted for decades. Regarding the “hard” problem, the introduced model is as incomplete as Quantum Mechanics is. It is claimed that solving the “hard” problem requires devising a new kind of quantum computer, which should be able to accept (non-Boolean) hidden variable values as input data and to replace the statistical Born’s rule of Quantum Mechanics with a deterministic threshold condition.

Abstract
Objectives: Limited information is available about the biological characterization of peri-implant soft tissue at the transcriptional level. The aim of this study was to investigate the effect of dental implant on the gingival tissue in vivo by using paired samples and compare the differences between peri-implant and periodontal gingiva at the transcriptional level.Methods: Paired peri-implant soft tissue and periodontal gingiva tissue from 6 patients were obtained, and the pooled RNAs were analyzed by deep sequencing. Venn diagram was used to further screen out differentially expressed genes in every pair of samples. Annotation and enrichment analysis was performed. Further verification was done by quantitative real-time PCR.Results: A total of 3549 genes including were found differently expressed between peri-implant and periodontal groups. The Venn diagram further identified 185 genes differentially expressed genes (DEGs) in every pair of samples, of which the enrichment analysis identified significant enrichment for cellular component was associated with external side of plasma membrane, for molecular function was protein binding, for biological process was immune system process, and for KEGG pathway was cytokine-cytokine receptor interaction. Among the DEGs, CST1, SPP1, AQP9 and SFRP2 were verified to be upregulated in peri-implant soft tissue.Conclusions: Peri-implant gingiva showed altered expressions of several genes related to the cell-ECM interaction.Clinical Relevance: At the transcriptional level, healthy periodontal is alternative to the healthy peri-implant soft tissue as the control of peri-implantitis to a large extent, except in the research related to cell-ECM interactions.

Abstract
SARS-CoV-2 has been shown to remain infectious on surfaces from hours to days depending on the surface type and environmental factors. The presence of virus on the cloth surface may pose a risk of disease transmission during use and handling. This study aimed to investigate the virucidal effect of hydrogen peroxide against SARS-CoV-2 virus on several types of fabrics. The SARS- CoV-2 virus at a concentration similar to viral load from a throat swab of a positive COVID patient was used to test the virucidal effect of hydrogen peroxide at different concentrations and different time points on different types of fabrics using VERO E6 cell culture. This study showed that the SARS-Cov2 soaked on different types of fabrics was killed within 30 s of exposure to hydrogen peroxide. Hydrogen peroxide showed a potent virucidal effect on SARS CoV-2 on different types of fabrics.

Published: August 2022

Abstract
Background
Esophagogastric devascularization and splenectomy (EGDS) is widely used to treat patients with portal hypertension in China. This study aimed to determine the risk factors of rebleeding after EGDS and evaluate the effect of portal vein thrombosis (PVT) on rebleeding during the postoperative period after EGDS.
Methods
Cirrhotic patients with portal hypertension who had undergone EGDS were included. The patients were assigned to either the rebleeding or the non-rebleeding group with follow-up time.
Results
A total of 138 consecutive patients who underwent EGDS and met the criteria were included in this study. The 3-year and 5-year rebleeding rates of all patients were 18.12% (25/138) and 27.54% (38/138), respectively. The total bilirubin (TBIL) (HR: 2.392, 95% CI 1.032–5.545, p = 0.042) and PVT (HR: 3.345, 95% CI 1.477–7.573, p = 0.004) were identified as the predictors of 3-year rebleeding in univariate analysis. Multivariate analysis revealed that the PVT (HR: 3.967, 95% CI 1.742–9.035, p = 0.001) was an independent factor. Hemoglobin > 87.5 g/L (HR: 3.104, 95% CI 1.283–7.510, p = 0.012) and PVT (HR: 2.349, 95% CI 1.231–4.483, p = 0.010) were the predictors of 5-year rebleeding in multivariate analysis. Albumin > 37.5 g/L was the only independent predictor of 3-year and 5-year rebleeding in patients with PVT.
Conclusions
The PVT is associated with 3-year and 5-year rebleeding in patients after EGDS but not 10-year rebleeding. Hemoglobin > 87.5 g/L is another predictor of 5-year rebleeding. High albumin levels may serve as a predictor of 3-year and 5-year rebleeding risk in patients with PVT.
A New Centrality Measure and Visualization Technique Using Multiple-Parent Nodes of Earthquakes Based on Correlation-Metric
Authors: Yamagishi Yuki , Saito Kazumi , Hirahara Kazuro , Ueda Naonori 
Published: August 2022

Abstract
In this paper, we address the problem of earthquake declus-tering, and propose a k-nearest neighbors approach based on the selection of multiple-parent nodes with respect to each of the given earthquakes , which can be regarded as a natural extension of the conventional correlation-metric method based on the selection of a single-parent node. Based on this approach, we develop a new centrality measure that exploits link weight assigned by a logarithmic-distance scheme and a new technique of individually visualizing each set of child nodes with respect to given target earthquakes. For experimental evaluation, we used an earthquake catalog covering Japan and selected 24 earthquakes that caused considerable damage or casualties. We first show that our proposed centrality measure using a logarithmic-distance scheme can rank these 24 major earthquakes higher than four link-weighting schemes (i.e., uniform, magnitude, inverse-distance, and normalized-inverse-distance weighting) and conventional single-parent selection. We then show that unlike the conventional approach to simultaneously visualizing all the events in the catalog, our proposed technique can produce a naturally interpretable classification result for these 24 major earthquakes, by individually visualizing each set of the first to k-th child nodes with different colored markers plotted in the directly interpretable spatio and temporal metrics. As a consequence, we confirm that our approach based on multiple-parent selection is vital and promising.

Published: August 2022

Abstract
Internet of Things (IoT) applications are growing in popularity and utility leading towards more comforts and conveniences with diversified use cases. However, there are security concerns as IoT technology is made up of heterogeneous devices, protocols and standards. Therefore, the environment might have inherent security issues due to lack of an integrated security framework. Security of internet of things applications is thus crucial for the growth of such applications in the real world. Towards this end, we have proposed a series of security schemes in our prior work. In this paper, we proposed an integrated framework for Leveraging Security of Internet of Things Application (LSITA) with Remote Patient Monitoring System (RPMS) use case. The framework is named as Integrated IoT Security Framework which is realized with different schemes to have privacy and end to end security. The framework enables cloud assisted authentication, secure communications among parties involved in IoT application and an improved key sharing model for multi-user data analytics environment. Different security schemes work together with seamless integration. Remote Patient Monitoring System is the case study built to evaluate the proposed framework. Empirical results revealed that the proposed framework has holistic approach to security of IoT applications. It has potential to trigger further research in the area of IoT security.

Abstract
On 7 August 2020, a large-scale catastrophic landslide was triggered by extreme rainfall at Osan village, Gokseong County, South Jeolla Province, South Korea. The initiation mechanism of the Gokseong landslide was different from those typical landslides that occurred in South Korea. Despite the relatively low elevation and slope degree, the landslide had a long runout distance of about 640 m over a total vertical distance of 90 m. A detailed field investigation and chemical analysis were conducted to understand the possible mechanisms for the high-speed and long-runout behavior of the landslide. The terrain controlled the motion behavior of the landslide and the seepage was observed at the whole landslide body. The clay-rich soils covered on granite bedrock of the landslide deposition area from the rice paddy field to the landslide crown. The results of this study may provide basic data for further research on the mechanisms for landslide initiation and propagation.

Abstract
Background: Vascular surgery of the inguinal area can be complicated by persistent lymphatic fistulas. Rapid and effective treatment is essential to prevent infection, sepsis, bleeding, and possible leg amputation. Current data on irradiation of lymphatic fistulas lacks recommendation on the appropriate individual and total dose, the time of irradiation, and the target volume. Presumably, a dose of 0.3-0.5 to 1-12 Gy should be sufficient for the purpose. Currently, radiotherapy is a “can” recommendation, with a level 4 low evidence and a grade C recommendation, according to the DEGRO S2 guidelines. As part of a pilot study, we analyzed the impact and limitations of low-dose radiation therapy in the treatment of inguinal lymphatic fistulas.Patients and Methods: As part of an internal quality control project, patients with lymphatic fistulas irradiated in the groin area after vascular surgery for arterial occlusive disease (AOD) III-IV, repair of pseudo aneurysm or lymph node dissection due to melanoma were selected, and an exploratory analysis on retrospectively collected data performed.Results: Twelve patients (10 males and 2 females) aged 62.83 + 12.14 years underwent open vascular reconstruction for stage II (n= 2), III (n=1), and IV (n=7) arterial occlusive disease (AOD), lymph node dissection for melanoma (n=1) or repair of a pseudoaneurysm (n=1). Surgical vascular access was obtained through the groin and was associated with a persistent lymphatic fistula, secreting more than 50 ml/day. Patients were irradiated five times a week up to a maximum of 10 fractions for the duration of the radiation period. Fraction of 0.4 Gy were applied in the first 7 cases, while 5 patients were treated with a de-escalating dose of 0.3 Gy. There was a resolution of the lymphatic fistula in every patient without higher grade complications.Conclusion: Low-dose irradiation of the groin is a treatment option for persistent lymphatic fistula after inguinal vascular surgery.

Published: August 2022

Abstract
Being the first hybrid-constellation global navigation system, China’s BeiDou navigation satellite system (BDS) has been entirely constructed since July 2020 and provides open services for worldwide users. Due to the natural sensitivity of satellite tracking techniques to geocenter motion, BDS has the capability to determine the geocenter coordinates independently. This study aims to improve the precision of geocenter coordinates derived from BDS. To that end, 3-year sets of daily geocenter coordinates have been determined with BDS observations. Different solar radiation pressure models, including the empirical CODE orbit model (ECOM), the extended ECOM model (ECOM2), and the adjustable box-wing (ABW) model, have been applied for the BDS geocenter estimation. We show that the ABW model appears to mitigate the draconitic signal of BDS and reduces the amplitude of the annual signal by factors of 5.4 and 2.1 w.r.t. ECOM and ECOM2 cases. Furthermore, we studied the impact of BDS constellation configuration on the geocenter estimation. The results indicate that the inclusion of IGSO satellites significantly mitigates the spurious signals in the spectra of the geocenter coordinates, with amplitudes of the annual signal and 3-cpy signal reduced by (28%, 14%), (33%, 61%), and (65%, 45%) for ECOM, ECOM2, and ABW cases, respectively. Meanwhile, the amplitude of the 7-day signal related to the revolution period of MEO satellites is also reduced by 43–60% after the inclusion of IGSO satellites. Thus, the MEO + IGSO hybrid configuration and ABW model are recommended for BDS to determine the geocenter. The annual amplitudes of the derived geocenter coordinates are 1.3, 3.6, and 5.5 mm, compared to 3.7, 3.2, and 5.0 mm for the ILRS solution in the X, Y, and Z components, respectively. Particularly, in the Z component, the BDS constellation characteristics lead to a difference of 15 mm in the amplitude of the 3-cpy signal compared to the ILRS solution.
Algebra with ternary cyclic relations, representations and quark model
Authors: Abramov Viktor , Groote Stefan , Lätt Priit 
Published: August 2022

Abstract
We propose a unital associative algebra, which is motivated by a generalization of the Pauli exclusion principle proposed within the framework of the quark model. The generators of this algebra satisfy the following relations: The sum of squares of all generators is equal to zero (binary relation) and the sum of cyclic permutations of factors in any triple product of generators is equal to zero (ternary relations). We study the structure of this algebra and calculate the dimensions of spaces spanned by homogeneous monomials. It is shown how the algebra we propose is related to irreducible representations of the rotation group. Particularly we show that the 10-dimensional space spanned by triple monomials is the space of a double irreducible unitary representation of the rotation group. We use ternary q- and q- -commutators, where q,q- are primitive 3rd order roots of unity, to split the 10-dimensional space spanned by triple monomials into a direct sum of two 5-dimensional subspaces. We endow these subspaces with a Hermitian scalar product by means of an orthonormal basis of triple monomials. In each subspace there is an irreducible unitary representation so(3) -> su(5). We calculate the matrix of this representation and the structure of matrix indicates a possible connection between our algebra and the Georgi-Glashow model.

Abstract
In southeastern Nigeria, gullies occurrence has seriously threatened humans and the environment. In this study, through a detailed field survey, geotechnical and geomorphological investigation, the erodibility extent of two erosion-prone geologic units in southeastern Nigeria was assessed. According to field observations, the investigated gullies were primarily composed of loose lateritic unconsolidated soils from the Ajali and Nanka geological formations. Based on the grain size study, it was discovered that the soil components for the Ajali and Nanka formations, respectively, contained gravel (0 − 3% and 5 − 22.5%), sand (7.75 − 95.0% and 66.5 − 89%), and fines (4.42 − 17.7% and 4.7 − 22.2%). The soil permeability coefficients ranged from 1.13 x 10− 5 to 2.45 x 10− 4 m/s and 6.18 x 10− 5 to 5.25 x 10− 4 m/s for the Ajali and Nanka formations, respectively. The MDD ranged from 1.69 to 1.90g/cm3 and 1.72 to 2.10g/cm3, whereas OMC ranged from 11.0 to 14.30% and 12.12 to 18.10% in the compaction test. The NMC results and the Atterberg limit indicate that the soils are non-plastic to low-plastic. The values for soil cohesion range from 0 − 6 kPa to 1 − 7 kPa. The friction angle ranges from 23 − 28o and 32 − 38o. The geomorphological characteristics revealed that the region is characterized by uneven topography and severe gully slope gradients, with the gullies within the Ajali Formation being more frequently linked with landslides. Both formations are vulnerable to erosion, according to the research. In order to combat this awful disaster, some type of mitigation strategy must be employed.

Abstract
Studies on the utilization of molecular and isotopic proxies for the characterization of organic matter (OM) sources and environmental conditions in lakes have been well documented globally. Nevertheless, inland lacustrine salt basins remain less well studied, particularly in tropical sub-saharan Africa. In this study, we quantified OM sources and evaluated the effects of salt deposit and barite mining on the distribution of n -alkanes in saline and freshwater Gabu lakes sediment cores, Southeast Nigeria using elemental, bulk carbon isotope ratios and biomarker distributions. Our results indicate a system inundated with comparable proportions of vascular plant leaf waxes (mean = 56.6%) and submerged/floating macrophytes (mean = 41.1%) with minor contribution from algae/photosynthetic bacteria (mean = 2.3%). The scenario indicate a shallow water system that predominantly preserved long chain n -alkanes derived from vascular plant leaf waxes and macrophytes. The capacity of macrophyte to biosythesize long chain n-alkanes most likely reflects adaptation of these organisms to partial exposure to the atmosphere. The occurrence in moderate abundance of C 17 and C 19 n -alkanes and the near absence of other low molecular weight (LMW) n -alkanes in the saline lake was linked to the effect of salt stress. The absence of LMW n -alkanes in freshwater lake was associated with barite hydrolysis and acidification accompanying mining activity. Our results have demonstrated that long chain n -alkanes of terrestrial and submerged/floating macrophyte origins are better preserved under conditions of salinity and acidification in inland shallow lakes than those derived from algae/bacteria.
