High Accuracy, 6-DoF Simultaneous Localization and Calibration using Visible Light Positioning
Authors: Chen Junye , Zeng Dinghao , Yang Chen , Guan Weipeng
Published: April 2022

Benefiting
from the development of image sensors and the popularity of light-emitting
diode (LED) lighting technology, visible light positioning (VLP) technology
based on image sensors has ushered in vigorous development and broad prospects,
which can provide low-cost and high-accuracy position service. However, the
existing approaches require dense LEDs or sensors such as gyroscopes to assist
positioning, which limit the area and lower the accuracy of positioning because
of the errors from imperfect sensors. In this paper, we propose a simultaneous
localization and calibration VLP method based on double coplanar circular LED
lights aiming to get rid of the dependence on additional sensors and dense LED
transmitters. By the pinhole camera model and the perspective projection of
circle, our proposed method extends the available position area and relaxes the
required quantity of LED to two. The experiment result shows that our system
has a mean 3D positioning accuracy of 7.91cm, a mean angle error of less than
1.6°, and an average latency of 182ms on mobile devices.
A Hybrid ConvLSTM-based Anomaly Detection Approach for Combating Energy Theft
Authors: Gao Hong-Xin , Kuenzel Stefanie , Zhang Xiao-Yu
Published: April 2022

In a conventional power grid, energy theft is difficult to detect due to limited communication and data transition. The smart meter along with big data mining technology leads to significant technological innovation in the field of energy theft detection. This paper proposes a convolutional long and shortterm memory (ConvLSTM) based energy theft detection (ETD) model to identify electricity theft users. In this work, electricity consumption data is reshaped quarterly into a 2-dimensional matrix and used as the sequential input to the ConvLSTM. The convolutional neural network (CNN) embedded into the long short-term memory (LSTM) can better learn the features of the data on different quarters, months, weeks, and days. Besides, the proposed model incorporates batch normalization. This allows the proposed ETD model to support raw format electricity consumption data input, reducing training time and increasing the efficiency of model deployment. The final experimental results show that the proposed ConvLSTM model exhibits good robustness. It outperforms the multilayer perceptron (MLP) and CNN-LSTM in terms of performance metrics and model generalization capability.
Adaptive Differentiation Filter
Authors: Zhang Tianli
Published: April 2022

As an essential tool for describing dynamic systems,
the concept of derivatives has been deeply rooted in all aspects of
modern science. In engineering practice, due to the complexity
and unknownness of the process of interest and the discreteness
nature of the collected data, people need a method to obtain the
derivative information of the dynamic process from these discrete
data, that is, numerical differentiation method. Unfortunately,
the disturbance introduced from the dynamic process itself and
the data acquisition process make the collected data noisy. The
existing numerical differentiation methods are susceptible to such
noise in the data, making them perform poorly when faced
with data from the real world. In this paper, a new numerical
differentiation method is proposed. It works like a 1-D FIR
filter whose tap coefficients are generated based on signal and
can estimate (higher-order) derivatives from noisy sampled data
of given functions. The proposed method shows much better
robustness against noise and consistency against signal frequency
varying than existing methods.

Our experience in approaching and managing pregnant ladies infected with covid 19at Prince Ali hospital in Jordan. Introduction: A new type of coronavirus was discovered in Wuhan, China in late. In Jordan, the first case was declared on the third of March 2020. Concerns about its implication on pregnant women wellbeing although the presentation of the disease varies from mild to severe. Pregnant women are more likely to get infected by SARS-CoV-2. Material and Methods: This descriptive cross - sectional study among pregnant women was performed at Prince Ali hospital from June 2020 until January 2021. A sample (n = 100) was selected using convenience sampling. We used Microsoft Excel (version 16.0) for descriptive statistical analysis. We used counts (frequency) to describe nominal variables. Results: We managed 100 pregnant women with COVID-19 aged 21–39 years at the Prince Ali hospital between June 2020 and January 2021, out of 1000 pregnant women who were admitted during that period. Fifteen patients were in their 1st trimester (15%), 31 in their 2nd trimester (31%) and 54 in their 3rd trimester (54%). Among the 100 pregnant women with COVID-19 on admission, 66 patients (66%) were asymptomatic, and 34 patients (34%) were symptomatic. 91 pregnant women completed their pregnancy, resulting in a live birth. Four pregnancies- (4%) ends in miscarriage, no vertical transmission was observed. Caesarean sections were performed in 21 patients (21%) due to obstetric indications. No maternal deaths and no ICU admissions was among our hospitalised patients. Conclusion: Pregnant women with COVID-19 have a low risk of experiencing severe disease and a lower likelihood of having complications as we noticed in our study.

Introduction: Diabetes is on the rise in sub-Saharan Africa, and particularly in Senegal where the latest prevalence estimates are around 3.4%. The region of Saint-Louis is a special case in terms of prevalence, since it far exceeds the national average, with more than 10% of the local population in 2011, or 30,000 to 40,000 cases. This epidemiological evolution of diabetes in the department of Saint-Louis is the direct consequence of many causes, including the lack of continuing medical education for paramedical staff. Material and methods: Our work proposes to return to the need for continuing medical education of paramedical staff in the department of Saint-Louis, through two surveys carried out with the diabetic people: a base line survey carried out before the training, and an end line survey after the diabetes training. The general objective is to assess the skills of health workers and their effectiveness in the management of diabetes and its complications, as well as the quality of diabetes management. Results: We found that the level of knowledge of nurses in charge of health posts and other paramedical staff is relatively heterogeneous. The average level obtained for right answers (66.76% during the base line survey and 82.4% during the end line survey) reflects the lack of continuing education concerning the diabetic disease in the department of Saint-Louis. Conclusion: The assessment of the knowledge of nursing staff in the department of Saint-Louis to which we proceeded is edifying. It is part of a logic of improving knowledge of diabetic disease and its complications. It shows that in the peripheral health structures, the need for continuing medical education is real.
Seeking the Hypocrisy of Biden Administration’s Human Rights Discourse from its Policy toward the Palestinian-Israeli Issue
Authors: Hanjing Yue
Published: April 2022

After taking office, the Biden administration raised human rights and other values to a much higher position in foreign policy than during the Trump administration, claiming that it would regard the protection of human rights in countries around the world as an important goal of its foreign policy. However, from the perspective of its policy practice on the Palestinian-Israeli issue, its relevant human rights discourse cannot stand the test of facts at all. Although Israel has seriously violated Palestinian human rights for a long time, the Biden administration has paid little attention to the Palestinian-Israeli issue and basically inherited the Trump administration’s policy on key issues of the Palestinian-Israeli conflict, which is tantamount to supporting Israel’s human rights violations. During the Gaza war that broke out in May 2021, the Biden administration refused to condemn Israel’s bombing of Gaza, repeatedly stressed that Israel’s actions were in self-defense, and not only continuously obstructed the Security Council’s adoption of statements condemning Israel and calling for a ceasefire between the two sides, it also approved arms sales to Israel. The above actions of the Biden administration fully reflect the hypocrisy of its human rights discourse.

Authors: David, L.K  , Ibeachu, P.C  , Hart, J.S
Published: April 2022

The aim of this study was to assess the anxiety and locomotive activity using elevated plus maze and open field tests in a konzo induced rat model. An experimental research method was used in this study. 20 male Wistar rats were used for this study. The twenty (20) albino Wistar rats were randomly selected into four groups of five rats each. Animal feeding was by oral ingestion. Animals were weighed with an electric weighing scale and the weights were recorded. Animals were closely observed for physical manifestations and clinical signs. Group 1 was the control group and the rats were fed with water and feed, group 2 was fed bitter cassava, group 3 was fed with bitter cassava and complain milk, while group 4 was fed with bitter cassava and bambara nut. The study lasted for 4 weeks and during this period, the weight and neurobehavioral assessment was done using weighing balance for weight determination, elevated plus maze and open field test for neurobehavioral assessment. Data was analyzed using Statistical Package for the Social Sciences (SPSS IBM version 23.0) and Microsoft excel 2019 edition. Values were expressed as mean±SD in descriptive statistics. One-way analysis of variance (ANOVA) was used to analyze the difference between the groups followed by least significant difference (LSD) post-hoc test. Confidence interval was set at 95%, and therefore p<0.05 was considered significant. The result shows weekly body weight differences in experimental animals. There was significant weight reduction in the body weight of the Konzo induced group experimental Wistar rats from week 1 to week 4 compared to the significant weight increase observed in the Konzo induced and complan milk fed group Wistar rats. The result from elevated plus maze showed that there was an improvement in anxiety level of Wistar rats fed with complan and bambara nut in terms of the time spent in the sections of the elevated plus maze in week 2 when compared to the week 1. In evaluating the locomotion impairment and anxiety level of wistar rats using Open Field Test, cassava-induced Konzo Wistar rat group, cassava-induced Konzo and complan milk fed group Wistar rats group and cassava-induced Konzo and Bambara nut (Okpa) fed Wistar rats group spent significantly more time in the open field apparatus in week 2 when compared to week 1. The improvement in anxiety and locomotor activity indicates the ameliorative effect of complan milk and Bambara nut (Okpa) and this is due to the protein content of complan milk and bambara nut. Hence a balance diet/protein containing food should be eaten along cassava processed foods.

Published: April 2022

It is well-known that the flip graph of $n$-vertex triangulated $2$-spheres is connected, i.e., each pair of $n$-vertex triangulated $2$-spheres can be turned into each other by a sequence of edge flips for each $n\ge 4$. In this article, we study various induced subgraphs of this graph. In particular, we prove that the subgraph of $n$-vertex flag $2$-spheres distinct from the double cone is still connected. In contrast, we show that the subgraph of $n$-vertex stacked $2$-spheres has at least as many connected components as there are trees on $\lfloor\frac{n-5}{3}\rfloor$ nodes with maximum node-degree at most four.

Статья посвящена изучению изменения бактериальной микробиоты в густых ржаных заквасках с направленным культивированием и спонтанного брожения в процессе длительного ведения. Исследования проводились в Санкт-Петербургском филиале ФГАНУ «НИИХП» при поддержке фонда РФФИ (проект № 19–016–00085 «Исследование видового разнообразия и симбиотических взаимодействий в микробиомах крахмало-белковых гидроколлоидных систем (хлебных заквасок)». Объектами исследований являлись четыре густые ржаные закваски, выведенные с использованием заквасочных культур микроорганизмов и спонтанного брожения. В разводочном цикле для выведения заквасок применяли чистые культуры молочнокислых бактерий Lacticaseibacillus paracasei/casei 5, Lacticaseibacillus paracasei/casei 63, Lactiplantibacillus plantarum 78 (закваска № 1) и Fructilactobacillus sanfranciscensis (закваска № 2) и дрожжей C. milleri Чернореченский из коллекции культур «Молочнокислые бактерии и дрожжи для хлебопекарной промышленности» СПБФ ФГАНУ «НИИХП». Закваски вели в лабораторных условиях в течение месяца. Показано, что применение чистых культур заквасочных микроорганизмов в технологии густой ржаной закваски приводит к доминированию лактобацилл и дрожжей и получению закваски с хорошими биотехнологическими показателями в первой фазе разводочного цикла. Однако в результате последовательных освежений заквасок наблюдается изменение видового состава лактобацилл. Показано, что применение вида F.sanfranciscensis в разводочном цикле является перспективным. В заквасках спонтанного брожения № 3 (без добавления молочной кислоты) и № 4 (с добавлением молочной кислоты) в разводочном цикле молочнокислые бактерии представлены родами Weissella, Pediococcus, Lactobacillus и Leuconostoc, в производственном цикле доминируют молочнокислые бактерии рода Lactobacillus. Внесение в водно-мучную питательную смесь молочной кислоты приводит к значительному снижению содержания в разводочном цикле не только нежелательных бактерий семейства Enterobacteriaceae, а и молочнокислых бактерий. В результате проведенных исследований установлено, что в отечественных густых ржаных заквасках длительного ведения, отличающихся хорошими биотехнологическими показателями, преобладает вид лактобацилл F. sanfranciscensis, что соответствует данным, представленным в иностранной литературе, и подтверждает, что данный вид характерен для ржаных густых заквасок и является перспективным для применения в качестве чистой культуры в составе стартовых композиций.

The complexity of integrity policies in administrative systems
According to the article, regulating administrative ethics is becoming increasingly complex. This article is based on a survey commissioned by the European Parliament on conflict of interest policies and their effectiveness in the EU Member States. The trends of administrative ethics are grounded on the growth of ethics bureaucracy, individualization of integrity policies – and broadening of the concepts such as conflict of interest. This kind of conceptualization indicates that unethical behaviour is linked to ever-widening areas of life, which in turn can complicate the design, implementation, and effectiveness of integrity policies. Also, systemic differences were found. The EU Member States, determined by a traditional bureaucratic system, regulate conflicts of interest through more detailed laws than the EU Member States whose systems are based more on managerial management practices. However, hybrid systems stand out as the most widely regulated.
Dynamics of Pine Turpentine Flow Depending on the Macrostructural Parameters of Wood on Swamped Soils
Authors:   Vologda State University, Novoselov Anatoly S.
Published: April 2022

Issues related to predicting the production of wood chemical products of sap (turpentine) of pine growing on peat soils, according to the data of radial growth in recent years (current growth), are quite relevant nowadays. It is well known that natural pine turpentine is superior in many respects to similar raw materials obtained in wood chemical industry by extraction. The experiment aimed at determining the specific relationship between the flow of pine turpentine and the wood macrostructure involved the following types of stands: control (naturally swamped), artificially drained (using gravity canals), as well as drained and anthropogenically disturbed by partial harvesting (in 2005). The study was carried out in the Sokol municipal district of the Vologda region (Sokol area forestry). The stands in the experiment are represented by high and medium density categories and dominated by pine. The stock of pine stem mass in drained conditions reaches 500 m3/ha. The express method of micro-wounding made it possible to determine the dynamics of resin flow in the shortest possible time, for 2013–2015 (during three months of the summer part of the growing season). A day after fixing the tubes in the tree bark, the turpentine flow was measured (individual and statistically average recording). Wood sampling in the radial section was carried out in 2019 by an increment borer; the increment of late and early wood, the width of the annual ring and the proportion of late wood in the annual layers were found. Statistical analyses of the obtained results were carried out: variation, correlation and regression. Student’s and Fisher’s tests were used as well. The positive effect of hydro-forest reclamation on the flow of turpentine during pine tapping was confirmed. It is possible to predict resin flow with an error probability of 43 % based on radial growth data in a pine forest on peat soils after artificial drainage. During the experiment in naturally swamped conditions it was not possible to predict trends in resin flow by radial growth of wood.

Aiming to verify the occurrence of predator mites in the Southern of Bahia State, we evaluate an agroforestry system (AFS) with açaí palm [Euterpe oleracea Mart. (Arecaceae)] intercropped with cupuaçu [Theobroma grandiflorum (Willd. Ex Spreng.) K. Schum. (Malvaceae)] in the Fazenda Bom Sossego located in Porto Seguro municipality, Bahia. The samples were performed monthly at 15 plants of each species, from September 2019 to February 2020. We found a total of 458 predatory mites of 14 species and eight families, of which 295 were collected on açai and 163 on cupuaçu, with 13 species on each host, being Cheyletidae sp. unique on cupuaçu and Typhlodromus (Anthoseius) sp. on açaí palm. From those, four species are new records for each host. Our results highlight that joint cultivation of açaí palm and cupuaçu as AFS is suitable and useful considering biological control practices, since the hosts share more than 90% of predator species, improving the total diversity of beneficial organisms in the AFS. Açaí palm was recently reported as host for red-palm-mite (Raoiella indica Hirst, 1924, Tenuipalpidae), with records of high population density and damage, so the implementation and maintenance of an AFS in which the hosts may share predators instead of phytophagous is an advisable strategy of Integrated pest management (IPM) increasing the effects of natural biological control and decreasing the damage by pests and use of chemical control.

Tyrimo tikslas. Išanalizuoti NPL gimusių sveikų, išnešiotų naujagimių pagimdytų sveikų motinų žindymo ypatumus pirmaisiais gyvenimo metais. Tyrimo metodai. Atliktas mišrus (retrospektyvinis+perspektyvinis) tyrimas, kuriuo metu tirti III lygio Perinataliniame centre, turinčiame NPL vardą, gimę išnešioti (≥37 sav.), sveiki, išimtinai nuo gimimo tik žindyti 642 naujagimiai, gimę 2019 m. 642 sveikos naujagimių motinos buvo apklaustos telefonu apie žindymo ypatumus. Duomenys analizuoti naudojant statistinį duomenų analizės paketą „IBM SPSS Statistics 23“. Rezultatai. Iki 6 mėn. buvo žindyti beveik 2/3, o iki metų 59,4 proc. visų kūdikių. Dažniausios žindymo nutraukimo priežastys: asmeninės (26,2 proc.) ir kūdikio atsisakymas krūties (25,2 proc.). Analizuojant žindymo nutraukimą iki 3 mėn. ir 3-5 mėn. gauta jog dažniausia priežastis buvo nepakankama laktacija/alkanas vaikas (46,1 proc., 49,3 proc.). Naujagimių, maitintų krūtimi iki 3 mėn., motinos dažniau naudojo socialinius tinklus kaip šaltinį, žinioms įgyti,  negu ilgiau žindžiusios motinos. Motinos, kurios žindė 3-5 mėn, naudojo specialią literatūrą (14,1 proc.) statistiškai reikšmingai dažniau nei tos, kurios žindė iki 12 mėn. (p<0,05). Dažniausias informacijos šaltinis tarp moterų, kurios žindė 6-11 mėn. (44,6 proc.) ir 12 ir daugiau mėn. (42,2 proc.) yra asmeninė patirtis. Išvados. 76,8 proc. NPL gimusių naujagimių buvo  žindyti iki 6 mėn. bei  59,4 proc. ≥12 mėn. Dažniausios žindymo nutraukimo priežastys buvo asmeninės, kūdikio atsisakymas krūties bei nepakankama laktacija. Beveik pusė motinų, kurios žindė iki 3 mėn. amžiaus, reikšmingai dažniau kaip priežastį žindymo nutraukimui nurodė nepakankamą laktaciją/alkaną vaiką, rečiau žindymo sunkumus. Dažniausiai moterys nustojo žindyti iki 3-5 mėn. ir  ≥12 mėn. dėl  nepakankamos laktacijos ir asmeninių priežasčių. Motinos, kurios žindė iki 6-11 mėn., dažniausiai nustojo žindyti dėl to, nes kūdikis atsisakė krūties. Tyrimo metu taip buvo buvo rastos sąsajos tarp žindymo trukmės ir naudojamų informacijos šaltinių. Gauta, kad visos motinos, nepaisant to, kiek laiko žindė, daugiausiai rėmėsi asmenine patirtimi.

Published: April 2022

This study primarily determined the utilization of various library services by teacher education students and their academic performance. The study covered the libraries of Central Luzon State University and Tarlac State University during the second semester of academic year 2018–2019. A survey questionnaire was utilized in gathering the needed data. Statistical analysis employed the use of the following: frequency counts, percentages, mean, standard deviation, Pearson r, and multiple linear regression. The majority of the teacher education students were found to have a very good grade point average from the previous semester. The father’s highest educational attainment showed a strong positive correlation with academic performance. On the contrary, the mother’s occupation and monthly family income had weak to moderate negative correlations. The perceived usefulness of using the library into the academic works by teacher education students revealed a moderate positive correlation. Library satisfaction was found to have a moderate positive correlation with students’ academic performance. Father’s educational attainment, utilization, and satisfaction with library services were found to be positive predictors of students’ academic performance. However, the mother’s occupation and monthly family income seemed not variable predictors of students’ academic performance in the context of library utilization.

Four new polyhydroxylated steroids lobophysterols E–H (1–4), together with three known compounds (5–7), were isolated from the soft coral Lobophytum pauciflorum collected at Xisha Island, China. The structures of the new compounds were elucidated by extensive spectroscopic analysis and comparison with NMR data of structurally related compounds reported in the literature. The absolute configuration of 1–3 was determined by X-ray diffraction. All the compounds have assessed the cytotoxicity against HL-60, K562, and Hela cells. Compound 1 showed weak cytotoxicity against K562 cells with an IC50 value of 19.03 μM. In addition, compound 1 also showed a moderate anti-inflammatory effect in zebrafish.
