The current technological transformation has had an impact on many aspects, including the world of education. Campuses as providers of higher education are required to be able to transform to improve the quality of education with a technological approach. Smart campus is a technology that can integrate organizational business processes such as learning, library management, and other campus management. Smart campus can be integrated with smarthome. Smart home devices such as gadgets, laptops, speakers that can be controlled automatically can support academic activities. But security is crucial. Campuses as academic service providers must ensure information security for the continuity of academic activities. For that we need a vulnerability assessment on smarthomes to support smart campuses to ensure the security of the organization's business processes. In this study, we conducted vulnerability testing on smarthomes using the SQUARE method. testing targets teleconferencing and e-learning technologies. The results of this study are in the form of proposals for security requirements to mitigate the risk of network attacks on smarthomes.
User-defined operators

Published: May 2022

In recent years, complex data mining and machine learning algorithms have become more common in data analytics. Several specialized systems exist to evaluate these algorithms on ever-growing data sets, which are built to efficiently execute different types of complex analytics queries.
However, using these various systems comes at a price. Moving data out of traditional database systems is often slow as it requires exporting and importing data, which is typically performed using the relatively inefficient CSV format. Additionally, database systems usually offer strong ACID guarantees, which are lost when adding new, external systems. This disadvantage can be detrimental to the consistency of the results.
Most data scientists still prefer not to use classical database systems for data analytics. The main reason why RDBMS are not used is that SQL is difficult to work with due to its declarative and set-oriented nature, and is not easily extensible.
We present User-Defined Operators (UDOs) as a concept to include custom algorithms into modern query engines. Users can write idiomatic code in the programming language of their choice, which is then directly integrated into existing database systems. We show that our implementation can compete with specialized tools and existing query engines while retaining all beneficial properties of the database system.
Spontaneous contractions of the human thoracic duct—Important for securing lymphatic return during positive pressure ventilation?

Published: May 2022

AbstractThe thoracic duct is responsible for the circulatory return of most lymphatic fluid. The return is a well‐timed synergy between the pressure in the thoracic duct, venous pressure at the thoracic duct outlet, and intrathoracic pressures during respiration. However, little is known about the forces determining thoracic duct pressure and how these respond to mechanical ventilation. We aimed to assess human thoracic duct pressure and identify elements affecting it during positive pressure ventilation and a brief ventilatory pause. The study examined pressures of 35 patients with severe congenital heart defects undergoing lymphatic interventions. Thoracic duct pressure and central venous pressure were measured in 25 patients during mechanical ventilation and in ten patients during both ventilation and a short pause in ventilation. TD contractions, mechanical ventilation, and arterial pulsations influenced the thoracic duct pressure. The mean pressure of the thoracic duct was 16 ± 5 mmHg. The frequency of the contractions was 5 ± 1 min−1 resulting in an average increase in pressure of 4 ± 4 mmHg. During mechanical ventilation, the thoracic duct pressure correlated closely to the central venous pressure. TD contractions were able to increase thoracic duct pressure by 25%. With thoracic duct pressure correlating closely to the central venous pressure, this intrinsic force may be an important factor in securing a successful return of lymphatic fluid. Future studies are needed to examine the return of lymphatic fluid and the function of the thoracic duct in the absence of both lymphatic complications and mechanical ventilation.

Published: May 2022

AbstractThe time‐of‐day influence on neuromuscular function is well‐documented, but important details remain elusive. It is currently unknown whether males and females differ in their diurnal variation for optimal neuromuscular performance. The purpose of this study is to identify the time‐of‐day influence on neuromuscular function between sexes and determine whether these responses differ for the upper versus lower limbs. A group of males (n = 12) and females (n = 15) completed neuromuscular performance testing in the morning (07:00–09:00) and evening (17:00–19:00) on separate days in a randomized order. Maximal force, the normalized rate of force development, EMG, normalized EMG rise, and submaximal force steadiness were compared between morning and evening hours. The main findings show that maximal force was greater in the evening for the knee extensors (d = 0.570, p < 0.01) but not the elbow flexors (d = 0.212, p = 0.281), whereas maximal muscle excitation was greater in the evening for the biceps brachii (d = 0.348, p < 0.01) but not the vastus lateralis (d = 0.075, p = 0.526) with no influence of sex. However, force steadiness during knee extension was superior in the evening versus the morning for males (d = 0.734, p = 0.025) and compared to evening values for females (g = 1.19, p = 0.032). Overall, these findings show that time‐of‐day affects the knee extensors more than the elbow flexors and that diurnal variability between sexes appears to be task‐dependent.

AbstractThe loss of ten‐eleven translocation (TET2) methylcytosine dioxygenase expression contributes to the pathobiology of pulmonary arterial hypertension (PAH). However, whether the expression and activity of other TETs and DNA methyltransferases (DNMTs) are altered in PAH remains enigmatic. Therefore, our objective was to determine the expression of DNMT (1, 3a, and 3b) and TET (1, 2, and 3) and their total activity. We assessed the expression of DNMT and TET enzymes in the leukocytes and their activity in extracellular vesicles (EVs). Expression of DNMT (1, 3a, and 3b), TET (2 and 3) in leukocytes, and total activity in EVs, from PAH patients was higher than in healthy controls. Additionally, we noticed there were difference in expression of these epigenetic enzyme based on ethnicity and found higher DNMT1 and lower TET2/TET3 expression in Caucasian than Hispanic/African American (combine) patients. Since loss‐of‐function mutation(s) and down‐regulation of TET enzymes are associated with hematological malignancies and cytokine production, we determined the expression of genes that encode cytokines in samples of Caucasian and Hispanic/African American patients. Expression of IL6, CSF2, and CCL5 genes were higher in the leukocytes of Caucasian than Hispanic/African American patients, and CSF2 and CCL5 negatively correlated with the decreased expression of TET3. Interestingly, the expression of gene encoding CD34, a marker of myeloid and lymphoid precursor cells, and CD163, a monocyte/macrophage protein, was higher in the leukocytes of Caucasian than Hispanic/African American patients. Furthermore, Hispanic/African American patients having higher TET2/TET3 expression had higher pulmonary capillary wedge pressure. In conclusion, our results revealed higher DNMT1 and lower TET2/TET3 in Caucasian than Hispanic/African American patients together potentially augmented genes encoding inflammation causing cytokines, and CD34+‐derived immunogenic cells, and the severity of PAH.

AbstractThe sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA) restores intracellular Ca2+ ([Ca2+]i) to resting levels after muscle contraction, ultimately eliciting relaxation. SERCA pumps are highly susceptible to tyrosine (T)‐nitration, impairing their ability to take up Ca2+ resulting in reduced muscle function and increased [Ca2+]i and cellular damage. The mitochondrial antioxidant enzyme, superoxide dismutase 2 (SOD2), converts superoxide radicals into less reactive H2O2. Heterozygous deletion of SOD2 (Sod2+/−) in mice increases mitochondrial oxidative stress; however, the consequences of reduced SOD2 expression in skeletal and cardiac muscle, specifically the effect on SERCA pumps, has yet to be investigated. We obtained soleus, extensor digitorum longus (EDL), and left ventricle (LV) muscles from 6 to 7 month‐old wild‐type (WT) and Sod2+/− female C57BL/6J mice. Ca2+‐dependent SERCA activity assays were performed to assess SERCA function. Western blotting was conducted to examine the protein content of SERCA, phospholamban, and sarcolipin; and immunoprecipitation experiments were done to assess SERCA2a‐ and SERCA1a‐specific T‐nitration. Heterozygous SOD2 deletion did not alter SERCA1a or SERCA2a expression in the soleus or LV but reduced SERCA2a in the EDL compared with WT, though this was not statistically significant. Soleus muscles from Sod2+/− mice showed a significant reduction in SERCA’s apparent affinity for Ca2+ when compared to WT, corresponding with significantly elevated SERCA2a T‐nitration in the soleus. No effect was seen in the EDL or the LV. This is the first study to investigate the effects of SOD2 deficiency on muscle SERCA function and shows that it selectively impairs SERCA function in the soleus.

Published: May 2022

Abstract
This study aimed to explore potential biomarkers and molecular mechanisms in preeclampsia (PE) progression. Gene expression profiles of GSE147776 and GSE96984 were downloaded, followed by the identification of common differentially expressed genes (co-DEGs) and common differentially expressed lncRNAs (co-DElncRNAs) in PE patients between the two datasets. Key genes were identified using gene set enrichment analysis (GSEA), followed by functional enrichment analyses. Subsequently, the miRNAs of key genes and miRNA-related lncRNAs were predicted, followed by the construction of the lncRNA–miRNA–gene ceRNA network. Furthermore, the key genes associated with different gestational stages were identified. As a result, 192 co-DEGs and 16 co-DElncRNAs were revealed from the two datasets. Based on two outstanding PE-associated pathways, including glaucoma and PE, identified by GSEA, ten key genes, including IGFBP1, CORIN, and C3, were revealed. Key genes, including IL1A and IL1B, were enriched in the developmental process involved in reproduction. Furthermore, ceRNAs, such as LINC00473-miR-4476-IL1A, LINC00473-miR-1291-IL1B, and NAV2-AS4-miR-6131-REN, were identified. Moreover, REN expression was significantly upregulated in the first- and second-trimester placentae compared to C-section-term placentae. In conclusion, these key genes may serve as novel biomarkers for PE. The detection of REN expression may help in the early prediction of PE and the initiation of prophylactic medical treatment.

Abstract
Stainless steel is known for its superior corrosion resistance in industrial applications. In this work, corrosion modeling of stainless steel 316L is presented using artificial neural networks. The experimental setup consists of a loop containing stainless steel elbow with simulated seawater of known concentration continuously flowing at a specific flow rate, thus allowing to study the effect of flow dynamics and salt concentration on corrosion. Electric field mapping setup is used to collect the voltage and current information along with the temperature of the elbow section. In addition to modeling, characteristics of the observed scale deposits are also studied in-depth and briefly reported in this work.
On Dixon’s ‘dangerous idea’
Authors: Longa Víctor M. , López-Rivera Juan J. 
Published: May 2022

Abstract
In his book Are some languages better than others?, the leading linguist R.M.W. Dixon put forward what we refer to as ‘Dixon’s dangerous idea’, i.e. the idea that linguistics should evaluate the relative worth of languages and provide some general criteria for deciding whether certain languages can be taken to be better or worse than others. Although it is obviously licit to raise this question, Dixon’s arguments when answering it are inaccurate, thus spreading a dangerous idea. This article critically discusses Dixon’s proposals and shows how his arguments draw on arbitrary and decontextualized criteria, and on naive evolutionary ideas of absolute fitness.

Abstract

Objectives
Endocrinopathy can occur as a postoperative sequel in children treated for supratentorial tumors (STTs). We assessed prediction of a residual hypothalamic/pituitary insufficiency (HPI) in these patients and factors associated with prolonged length of hospital stay (LOS).

Methods
This is a retrospective cohort study of children who had surgery for STTs in two tertiary centers in Saudi Arabia (2009–2019). We assessed PICU postoperative management and risk of HPI. Data were analyzed using SPSS V24.0 and a logistic regression model for a prediction of a prolonged LOS.

Results
Data included 55 children (1–18 years, mean 9.5 ± 4.9 years) who required STT surgeries, 32 (54%) females. Craniopharyngioma (27.3%) was the commonest STTs and 20% of patients had initial symptoms of HPI. PICU management included the use of different types of intravenous fluids (IVFs) and medications such as steroids and desmopressin (DDAVP). An early postoperative DI was reported in 21.8% (n=12/55). Residual HPI included 24 (43.6%) presumed cortisol deficient and 18 (32.7%) central DI patients. Risk factors for postoperative HPI were female gender, age <6 years, headache and preoperative pituitary symptoms. LOS (Median=25.5 ± 12.2 days) was significantly prolonged in patients who required two or more doses of DDAVP [B=13; 95% CI= (1.7–24.3) days] and reduced in patients who had suspected preoperative HPI [B=−19.6; 95% CI= (−31.1, −8.2) days].

Conclusions
Prediction of postoperative HPI in pediatric STTs enhances an early initiation of treatment in PICU and reduces LOS. A meticulous use of IVF and medications supervised by a multidisciplinary team is essential for a favorable outcome.

Published: May 2022

Abstract
The Colombian weasel, Neogale felipei, previously included in the genus Mustela, is considered the rarest carnivore in the Neotropics and is known from only eight localities in Colombia and Ecuador. It is currently classified as Vulnerable, but little is known about the direct threats that the species faces. We present a new locality record for N. felipei in the Andes of southwestern Colombia based on a road-killed specimen. The record is relevant because it provides additional information about morphological variation and describe a new threat to its populations that even affects individuals within protected areas such as the Puracé National Park, where the specimen was found.
On-line monitoring of steel ball stamping by mechatronics cold heading equipment based on PVDF polymer sensing material
Authors: Wang Xing , Wu Mingming , Wang Jianglong 
Published: May 2022

Abstract
In order to explore the influence of cold heading equipment based on polyvinylidene fluoride (PVDF) polymer sensing material on steel ball stamping, a new method was proposed to reflect the defects of cold heading forming of steel ball by load signal. PVDF piezoelectric film is used as the sensor design of force and support structure of steel ball cold heading electromechanical sensor model. PVDF piezoelectric thin film force sensor is used for the structural optimization and simulation. The structural parameters affecting the natural frequency are numerically analyzed by MATLAB software. The mapping relationship between the external load and the output load of the sensor is obtained by using ANSYS software, and the simulation curve of the natural frequency of the sensor is compared with the theoretical curve to verify the factors affecting the natural frequency. The results show that the nonlinear error of sensors refers to the measured curve and the maximum deviation between the fitting line and the percentage of full-scale output.

These charming characteristics induce Te a possible nominee for applications in field-effect transistors, IR acousto-optic deflectors, solar cells, self-developing holographic recording devices, photoconductors, gas sensors, radiative cooling devices, and topological insulators. The developments in these areas are incorporated in great detail. This study opens up the possibility of designing novel devices and considering modern applications of Tellurium.
The access to justice gap and the rule of law crisis in Poland
Authors: Winczorek Jan , Muszyński Karol 
Published: May 2022

SummaryThe article discusses selected problems of access to justice in Poland as an important context for the rule of law crisis since 2015. The difficulties in formally addressing justiciable problems were illustrated by the findings of empirical studies conducted in 2015 and 2018. The article argues that having experienced obstacles in addressing their justiciable issues, Polish society has developed what can be termed a highly rational stance towards the legal system, which can be expected to contribute to its reluctance to actively oppose the sweeping reforms of the judiciary introduced by populists. Understanding the effects of inaccessibility of justice combined with insufficient options to resolve justiciable problems outside of the law and legal institutions is an important addition to the prevailing politics- and culture-centred approaches to understanding of the long-standing multifaceted conflict around the judiciary in Poland.
