Three-dimensional force plates are important tools for biomechanics discovery and sports performance practice. However, currently, available 3D force plates lack portability and are often cost-prohibitive. To address this, a recently discovered 3D force sensor technology was used in the fabrication of a prototype force plate. Thirteen participants performed bodyweight and weighted lunges and squats on the prototype force plate and a standard 3D force plate positioned in series to compare forces measured by both force plates and validate the technology. For the lunges, there was excellent agreement between the experimental force plate and the standard force plate in the X-, Y-, and Z-axes (r = 0.950–0.999, p < 0.001). For the squats, there was excellent agreement between the force plates in the Z-axis (r = 0.996, p < 0.001). Across axes and movements, root mean square error (RMSE) ranged from 1.17% to 5.36% between force plates. Although the current prototype force plate is limited in sampling rate, the low RMSEs and extremely high agreement in peak forces provide confidence the novel force sensors have utility in constructing cost-effective and versatile use-case 3D force plates.

Published: May 2023

Emergency Communication Systems (ECS) are network-based systems that may enable people to exchange information during crises and physical disasters when basic communication options have collapsed. They may be used to restore communication in off-grid areas or even when normal telecommunication networks have failed. These systems may use technologies such as Low-Power Wide-Area(LPWAN) and Software-Defined Wide Area Networks (SD-WAN), which can be specialized as software applications and Internet of Things (IoT) platforms. In this article, we present a comprehensive discussion of the existing ECS use cases and current research directions regarding the use of unconventional and hybrid methods for establishing communication between a specific site and the outside world. The ECS system proposed and simulated in this article consists of an autonomous wireless 4G/LTE base station and a LoRa network utilizing a hybrid IoT communication platform combining LPWAN and SD-WAN technologies. The LoRa-based wireless network was simulated using Network Simulator 3 (NS3), referring basically to firm and sufficient data transfer between an appropriate gateway and LP-WAN sensor nodes to provide trustworthy communications. The proposed scheme provided efficient data transfer posing low data losses by optimizing the installation of the gateway within the premises, while the SD-WAN scheme that was simulated using the MATLAB simulator and LTE Toolbox in conjunction with an ADALM PLUTO SDR device proved to be an outstanding alternative communication solution as well. Its performance was measured after recombining all received data blocks, leading to a beneficial proposal to researchers and practitioners regarding the benefits of using an on-premises IoT communication platform.

Published: May 2023

Isometric leg press (ILP) and countermovement jump (CMJ) are commonly used to obtain strength- and power-related variables with important implications for health maintenance and sports performance. To enable the identification of true changes in performance with these measurements, the reliability must be known. This study evaluates the between-session reliability of strength- and power-related measures obtained from ILP and CMJ. Thirteen female elite ice hockey players (21.5 ± 5.1 years; 66.3 ± 8.0 kg) performed three maximal ILPs and CMJs on two different occasions. Variables from the ILP (peak force and peak rate of force development) and CMJ (peak power, peak force, peak velocity, and peak jump height) were obtained. The results were reported using the best trial, an average of the two best trials, or an average of three trials. The intraclass correlation coefficient (ICC) and coefficient of variation (CV) were high (ICC > 0.97; CV < 5.2%) for all outcomes. The CV for the CMJ (1.5–3.2%) was lower than that for the ILP (3.4–5.2%). There were no differences between reporting the best trial, an average of the two best trials, or an average of the three trials for the outcomes. ILP and CMJ are highly reliable when examining strength- and power-related variables in elite female ice hockey players.

Published: May 2023

Arthropods are key nodes for the provision of ecosystem services such as pest control, but their response to land-use change is highly variable depending on the scale of analysis and the natural enemies’ life histories. We evaluate the effects of landscape- and local-scale variables of natural enemies’ communities on small-scale agriculture. We consider functional response traits to attain a mechanistic understanding of the effect of land-use changes on the biodiversity and resilience of natural enemies’ communities. Predator and parasitoid arthropods were collected from thirteen raspberry farms to estimate functional diversity, complementarity, and redundancy indices. We found no effects of landscape heterogeneity, local habitat, or management practices on natural enemies’ functional diversity. Regarding resilience, complementarity was high at most of the sites and was not affected by the landscape or local variables. However, redundancy was affected by two management practices. Weed control decreased natural enemies’ abundance as well as the abundance of walker generalist predators and flying specialist parasitoids, while habitat richness decreased flying generalist predators. These results highlight the importance of management when the landscape matrix is heterogeneous. We conclude that small-scale agriculture in a heterogeneous landscape supports a functionally diverse enemy community, potentially promoting the resilience of pest control to land-use change.

Published: May 2023

Hepatitis B (HB) vaccination is recommended for people with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). We aimed to assess the immune response to the HB vaccine and associated factors using the standard vaccination schedule among people with HIV (PWH) in China. A prospective study was carried out from 2016 to 2020 in Beijing, China. PWH were given three 20 μg doses of recombinant HB vaccine at 0, 1, and 6 months. Blood samples were taken within 4–6 weeks after each dose to evaluate the anti-HBs levels. A total of 312 participants completed vaccination and serologic testing. The seroconversion (anti-HBs ≥ 10 IU/L) rates following the first, second, and third doses of the vaccine were 35.6% (95% CI: 30.3–40.9%), 55.1% (95% CI: 49.6–60.7%), and 86.5% (95% CI: 82.8–90.3%), respectively, and the geometric means of the anti-HBs titers were 0.8 IU/L (95% CI: 0.5–1.6 IU/L), 15.7 IU/L (95% CI: 9.4–26.3 IU/L), and 241.0 IU/L (95% CI: 170.3–341.1 IU/L), respectively. In multivariate analysis, after three doses of vaccination, age, CD4 cell count, and HIV-RNA viral load were significantly associated with strong, moderate, and weak response, respectively. These findings confirm that these personal health conditions are related to the HB response. HB vaccination in PWH using the standard schedule was still highly effective in the context of early treatment initiation, especially among participants aged 30 years and younger.

Published: May 2023

Vaccination against COVID-19 is one of the highly effective preventative strategies to reduce morbidity and mortality associated with COVID-19 infection. The rapid approval of COVID-19 vaccination due to the raging pandemic, media coverage, anti-vaccination groups, and concerns about adverse effects associated with vaccination has given rise to COVID-19 vaccine hesitancy. Current evidence suggests that psychosomatic and nocebo-related adverse effects account for a significant proportion of common adverse effects following COVID-19 vaccination. The most common adverse effects are headache, fatigue, and myalgia, which are highly prone to nocebo effects. In our review article, we discuss the role of psychosomatic and nocebo effects in COVID-19 vaccination-related hesitancy, predictors of such effects, and strategies to reduce vaccine hesitancy. General education regarding psychosomatic and nocebo effects and specialized education for at-risk populations may reduce psychosomatic and nocebo-related adverse effects following COVID-19 vaccination, ultimately reducing hesitancy.
Conversion of Waste Synthesis Gas to Desalination Catalyst at Ambient Temperatures
Authors: Antia David D. J.
Published: May 2023

In this study, a continuous flow of a synthetic, dry, and acidic waste synthesis gas (WSG) (containing N2, H2, CO, CH4, and CO2) at ambient temperatures was first passed through a fixed bed reactor (FBR) containing halite + m-Fe0 and then a saline bubble column diffusion reactor (BCDR) containing m-Fe0. The FBR converted 47.5% of the CO + CH4 + CO2 into n-C0. Passage of the n-C0 into the BCDR resulted in the formation of the desalination catalyst (Fe0:Fe(a,b,c)@C0) + CH4 + CO + CO2 + CxHy, where 64% of the feed n-C0 was converted to gaseous products. The desalination pellets can remove >60% of the water salinity without producing a reject brine or requiring an external energy source. The gaseous products from the BCDR included: CxHy (where x < 6), CO, CO2, and H2.

Published: May 2023

Modern visualisation techniques offer great opportunities for visualising trace evidence, both fingerprint and footwear impression evidence. However, in the case of the latter, opportunities presented by these techniques are used only to a small extent. This article is addressed to forensic technicians and experts in the field of footwear impression evidence and fingerprints examination. It aims to present and organise information about contrasting, visualising, and collecting the most common footwear impression evidence: three-dimensional impression, impressions of dry origin (i.e. left with dust) and of wet origin (i.e. left with mud/soil, blood or urine) on various types of surfaces. The authors hope that the expertise collected in this article will help increase the number of visualised and collected footwear impression evidence.
СТАН ТВЕРДИХ ТКАНИН ТИМЧАСОВИХ ЗУБІВ У ДІТЕЙ ІЗ ЗУБОЩЕЛЕПНИМИ АНОМАЛІЯМИ
Authors: Смоляр Н.І. , Лесіцький М.Ю.
Published: May 2023

Стан твердих тканин тимчасових зубів суттєво впливає на розвиток зубощелепної системи дитини. Каріозні ураження жувальних та апроксимальних поверхонь тимчасових зубів, передчасне видалення є причинами не лише формування зубощелепних аномалій та деформацій, але й порушення функцій жування та мови, що призводить до зниження самооцінки і порушення адаптації дитини в соціумі та є негативним фактором при формуванні її особистості. Усе це обумовлює необхідність проведення профілактичних заходів та своєчасного лікування карієсу молочних зубів. Мета дослідження. Вивчення поширеності та інтенсивності карієсу тимчасових зубів у дітей із зубощелепними аномаліями. Матеріал та методи дослідження. Для оцінки стану твердих тканин зубів обстежено 720 дітей віком 6-12 років м. Львова. Оцінку ураженості карієсом тимчасових зубів проводили згідно наступних показників: поширеності (у %) та інтенсивність карієсу за показником кп. Характер прикусу оцінювали за класифікаціями Енгля Е. (1889) та Калвеліса Д.А. Наукова новизна. У даному дослідженні було вивчено ураженість карієсом тимчасових зубів у дітей із зубощелепними аномаліями. Встановлено, що, в середньому, поширеність та інтенсиність карієсу тимчасових зубів у дітей із ЗЩА достовірно вищі порівняно із дітьми без ЗЩА. У результаті аналізу індексу інтенсивності карієсу поверхонь зубів виявлено, що, в середньому, на одну дитину із ЗЩА припадає 6,73 поверхні зуба, тоді як на одну дитину без ЗЩА – 4,29 поверхні зуба. На одну дитину із ЗЩА припадає, в середньому, 0,98 тимчасового зуба з ускладненим карієсом, тоді як на одну дитину без ЗЩА – на 78,18 %. Кількість передчасно видалених тимчасових зубів, в середньому, складало 0,26 тимчасового зуба, на одну дитину із ЗЩА та 0,07 зуба на одну дитину без ЗЩА. Висновки. Таким чином, отримані дані свідчать, що існує взаємозв’язок між наявністю карієсу тимчасових зубів та формуванням зубощелепних аномалій у дітей у ранньому та пізньому змінному прикусі, а також необхідності мотивації батьків до збереження стоматологічного здоров'я дітей. Схильність дитини до карієсу тимчасових зубів, може свідчити і про можливу схильність до формування зубощелепних аномалій в силу наявності порушення мінерального обміну в цілому організмі, зокрема в екосистемі порожнини рота, що обумовлює актуальність подальших досліджень.

Published: May 2023

The Constructive Curtain Project works in collaboration with ar¬chitecture to generate more performative interiors. The curtain is capable of bridging the divide between architecture and interior design by generating more habitable environments. This divide has been recognized since the eighteenth-century when upholsterers and architects diverged in their appreciation for the hard versus soft and the permanent versus impermanent. The disciplines grew further apart in the nineteenth-century with the emergence of the professional decorator causing architects to perceive that their well-articulated spaces were being corrupted.1

Which kind of imagination do we need to rethink Miami in the advent of sea-level rise? Most of the South Florida region was a subtropical wetland until just 120 years ago. In the land natives called Pa-hay-Okee (grassy river), we build a 20th-century industrial sprawl and completely transformed the ecology of the region by altering significant parts of the wild into rural. This is not an isolated story for South Florida. Today more than 50% of living organisms, plants, and ecological systems in the world are determined by human industrialization.

“The history of the theater is the history of the transfigura¬tion of the human form. It is the history of man as the actor of physical and spiritual events, ranging from naiveté to reflection, from naturalness to artifice. The materials involved in this transfiguration are form and color, the materials of the painter and sculptor. The arena for this transfiguration is found in the constructive fusion of space and building, the realm of the architect.”—Oskar Schlemmer1
GATOR House: A Typology of Resilience
Authors:   University of Louisiana at Lafayette, Young Sarah , McClure Michael ,   University of Louisiana at Lafayette, Emery McClure Ursula ,   Retired Professor, Louisiana State University
Published: May 2023

In the modern era, most buildings in southern Louisiana’s wet, hot, humid, and often volatile climate seek to resist the extreme conditions by creating a presumed impenetrable barrier. Since the advent of HVAC, levees, dams, and surge barriers, a construction culture of resistance has permeated the built environment. This has proven less than resilient and has resulted in billions of dollars in remediation and billions more tons of construction debris. Historically, buildings in this subtropical area were forced to employ every manner of passive systems to mediate their physical environment to the greatest extent possible. The GATOR house resists the false choices of historical vs. modern, man vs. nature, active vs. passive, and celebrates the complex interaction of the built, natural, and cultural systems of southern Louisiana. Geography is the description of how the signs of history have become forms, therefore the architectural project is charged with the task of revealing the essence of the geo-environmental context through the transformation of form. The environment is therefore not a system in which to dissolve architecture. On the contrary, it is the most important material from which to develop the project. - Vittorio Gregotti 1
Mirror Images

Published: May 2023

Somewhere near the surface of the glass and silver nitrate, a mirror’s image optically responds to a human observers’ movements, reflecting the environment based on the viewers position. As the viewer approaches the mirror, its’ appearance opens up a wider and deeper view of the room. It magnifies the image recognized by the perceiver and visually reflects the three-dimensional scene atop its flat surface. Nearly 40 years after Dan Grahams’ written reflections on the mental and visual appearance of the mirror image,1 the design for All Square, a restaurant and non-profit in Minneapolis, expands this interest. The name “All Square” is a reference to the notion that those who have paid their debts to society are square and free to move forward with a clean slate, as well as a nod to the shape of the fast-casual restaurant’s signature dish. The grill cheese eatery offers its formerly incarcerated employees a professional¬- development fellowship in addition to a living wage. To give the non-profit mission and branding of All Square a physical presence, the project uses the name and motif of the ‘Square’ as the starting point and repeats it at varying dimensions throughout the space. The square is materialized as mirrors and aluminum frames to form thresholds that divide and unify the large room.
Pre-Design Visualization: The Prospect of Real-Time Evaluative Methods in the Design Process
Authors:   South Dakota State University, Xu Fang
Published: May 2023

The rise of computer-generated imagery has significantly changed the landscape of architectural visualization. However, the digital turn brings little shift to the role of vi¬sualization in the architectural design process. Post-design visualization remains a dominant paradigm in practice. This paper advocates the development and adoption of pre-design visualization methods. Pre-design visualization transforms architectural visualization from a discrete and post-design task into a general action ubiquitous in all design stages and preceding formal decisions. Pre-design visualization affords a real-time visualized design environment that generates and fuses massive visual data of essential design information. Such a design environment considerably augments the dialogue between the architect and the formal scheme under devel¬opment, facilitating informed decision-making in a cyclical design process. The paper demonstrates the strengths of pre-design visu¬alization through three real-time design games that the author developed. These games allow the architect to initi¬ate, modify, and evaluate design schemes in an interactive 3D environment that features visualized physical contexts, adaptable weather and daylight systems, human performance simulation, visualized design parameters and statistics, and design evaluation tools. The following discussion illuminates the practical values of pre-design visualization for architects and different actors and stakeholders in multiple design sce¬narios. The paper is concluded by a discussion of immediate research directions for pre-design visualization: interoperabil¬ity of pre-design visualization tools with mainstream design programs in a data-driven, computational design workflow, simulation of complex person-environment interactions, and flexibility in media deployment.
Urban property taxes in Pakistan’s Punjab
Authors: Wani Shahrukh , Shaikh Hina , Harman Oliver
Published: May 2023

Property tax is a significantly under-utilised tax instrument in Punjab, accounting for only 6% of the total provincial tax. With a population of over 100 million, all of Punjab collects less urban property tax than the city of Chennai in India, home to about 10 million people. Punjab's cities have significant service delivery deficits. For example, only 35% of urban households in Punjab have piped water. These deficits will worsen in the absence of local financing that can be used to make public investments. This policy brief outlines the current landscape of property taxation in Punjab, highlights the significance of this source of public finance, and frames future policy direction, particularly the trade-offs between various valuation systems.

Enhancing the financial position of cities: Evidence from Kampala
Authors: Delbridge Victoria , Haas Astrid , Harman Oliver , Venables Anthony
Published: May 2023

The city of Kampala in Uganda provides an illustrative example of how institutional and administrative reform, without widespread policy change, can generate substantial increases in municipal revenues. Through the implementation of more efficient digitalised systems, attracting higher capacity staff, and a focus on the ‘citizen as a client’, the city has managed to increase own-source revenues three-fold from UGX 30 billion (US$8.2 million) in 2010/11 to UGX 90 billion (US$25 million) in 2018/191, as well as crowd in more central government and donor funds. These reforms were made possible by strong leadership, a political window to act, and strong support from development partners. What was striking was the administration’s reflection that its most significant success was not in doing something new, but rather in doing its job as it is meant to be done. Furthermore, the reforms contributed to achieving an investment-grade credit rating in 2015, creating the potential for increased funding opportunities for large-scale investments in the future. This, coupled with recent regulatory change to remove the previously restrictive 10 per cent cap on borrowing, provides promising new avenues for attracting investments. However, a number of stakeholders noted concerns that, despite overcoming regulatory hurdles, the city is still not equipped with the capacity to develop bankable plans and projects. For development partners, the example of Kampala highlights the need for collaboration to build capacity, both in reforming systems and in designing implementable strategies and bankable projects worthy of external finance. However, concerns around the way development finance skews prioritisation of projects, as well as the difficulties in providing for ongoing maintenance which are often not accounted for in development partner investments, were also highlighted.

Objective – The paper describes leisure activities and the non-profit sector in the field of leisure, the division of non-profit organizations, the definition of associations, marketing, and promotion of non-profit organizations.
Methodology – The research investigation is carried out through quantitative content analysis. We analyzed 1301 offered activities, which we further categorized. We carried out the analysis online using the Interactive Map of the Non-Profit Sector, which we supplemented by research on the websites of the Czech Union of Sport, Sokol, Orel, Pionýr, Junák – Czech Scout, the Brontosaurus Movement, and others, and by searching on individual websites. Furthermore, a questionnaire survey was used, where we contacted 280 associations electronically.
Findings – The return rate was 35%, and 98 respondents willingly completed the questionnaire. The research aims to analyze selected leisure facilities' current supply and demand. According to the obtained data, it is possible to state whether the leisure activity of the mediated association is pervasive and versatile. The research revealed specific gaps in the market. Other goals of the research are to find out what leisure facilities and services they provide, to reveal whether the selected leisure facilities also provide activities in the online environment and whether there is interest in the given activities on the part of the participants, to find out the methods of promotion of the selected leisure organizations and to determine the factors that, according to the selected leisure facilities affect the demand for leisure activities.
Novelty – Recommendations are presented that could ensure increased demand for leisure activities, including the use of modern technologies, which can also attract a large number of new interested parties, especially younger age groups, in the areas of programming, website creation, prevention of cyberbullying, cyber grooming, sexting or in the development of the ability to recognize disinformation within comprehensive digital competences.

Published: May 2023

Nas últimas décadas, a transição para a vida adulta tem vindo a tornar-se mais complexa e prolongada, não raras vezes intermitente e reversível. Este fenômeno tem dado visibilidade a uma série de constrangimentos que afetam o desenvolvimento das trajetórias dos jovens, dos quais se destaca a precariedade laboral e o desemprego, culminando em conjunturas NEET (not in employment, education or training). Para quem já enfrentava uma posição de maior vulnerabilidade a flutuações estruturais, os constrangimentos desencadeados pela pandemia de Covid-19 vieram ampliar e adensar as dificuldades dos jovens no processo de transição para a vida adulta. Enquanto terceira fase de um estudo de caso sobre os jovens que não estudam nem trabalham, neste trabalho propomo-nos a revisitar algumas das conclusões mais relevantes reunidas em etapas anteriores, relacionando-as com um conjunto de perceções geradas a partir de um focus group com participantes integrados numa resposta pública para jovens NEET do município de Sintra (Portugal) – razões, desafios e vivências da situação NEET; e perceções sobre o sistema educativo, transições e mercado de trabalho.

has magnetic resonance spectra broadened by hyperfine interactions, which decreases the signal contrast and thus degrades the magnetic field sensitivity. Here we propose multi-frequency composite pulse sequences to enhance the contrast of the measurement signal in the Rabi oscillation. We demonstrate that the sequence using five microwave frequencies enhances the signal contrast, improving the sensitivity by a factor of 2.3 compared to the conventional sequence.

Published: May 2023

Çiftlik hayvanlarında multisistemik enfeksiyon tablosu ve yüksek ekonomik kayıplara sebep olan pestiviruslar geniş konakçı spektrumuna sahiptirler. Bu viruslar konakçı spesifik olmadıklarından, türler arası geçiş epidemiyolojik yaygınlık açısından önemlidir. Keçilerde oluşan pestivirus enfeksiyonlarına bağlı olarak gebelerde abortlar, anomalili yavru doğumları ve verim kayıpları meydana gelebilmektedir. Bu araştırmada Burdur yöresinde yetiştiriciliği yapılan Honamlı keçilerinde pestivirus enfeksiyonunun seroprevalansının belirlenmesi amaçlanmıştır. Bu doğrultuda saf ırk özelliğinde 251 Honamlı keçisinden alınan kan serumu örnekleri ELISA yöntemiyle analiz edildi. Test edilen kan serumu numunesinin 115’i (%45,82) seropozitif olarak belirlendi. Örnekleme yapılan yerleşim bölgelerine göre seropozitiflik oranları %85,42-%8 arasında tespit edildi. Ayrıca pozitifliğin yaş gruplarına göre dağılımları da saptandı. Yaş grupları ve cinsiyet bazında belirlenen seropozitiflik oranları arasındaki farklılığın istatistiki açıdan önemsiz, ilçeler bazında belirlenen oransal farklılığın ise önemli olduğu belirlendi. Bu araştırma sonucunda Honamlı keçi ırkında ilk defa pestivirusların varlığı/yaygınlığı ortaya koyulmuştur. Bu durum bölgede pestivirus enfeksiyonlarının sirkülasyonda olduğunu ve ekonomik kayıplara yol açabileceğini göstermiştir.

This study investigated the genetic relatedness and characterization of Nile tilapia (Oreochromis niloticus) populations from Lake Bako, Mambilla Plateau and Lake Alau, Maiduguri using Mitochondrial DNA (mtDNA) D-loop sequences. Blood samples were collected from each individual of and preserved on an FTA card. DNA was extracted from the card using Aqualex extraction kits. Polymerase Chain Reaction was performed using a commercially available decamer primer: FISH COMUM D-LOOP F (5’-GGATTYTAACCCYTRCCC -3’) and (R:) as the forward primer and C. zilli_rev (5′ – AGTAAAGTCAGGACCAAGCC – 3′) as reverse primer. The results showed that, in total 117 variable sites were observed and Hap_1_Hap_40 was detected. Lake Alau population has 65.50 % A+T and 34.5% G+C, while 65.5% and 34.9% were the nucleotide composition of Lake Bako population. Both populations have 1.00 Haplotypes diversity. The nucleotide diversity observed in Lake Bako population is 0.0342, while 0.0285 were recorded in Lake Bako population. The average number of nucleotide differences of 26.61053 and 31.98421 were observed in Lakes Bako and Alau populations, respectively with and overall value of 29.996. The Neighbour-Joining phylogenetic tree revealed two major clusters. The genetic variation among population is 95.31%and within population is 4.69%. Populations of O. niloticus in Lakes Bako and Alau are genetically different. Lake Bako population seemed to have intact genetic structure. Both populations have high genetic diversity, hence have high potential for genetic improvement and conservation.
Smartphone Authentication with Lightweight Deep Learning
Authors: Kumar Gautam
Published: May 2023

Over the past decade, machine learning methods have found their way into a large variety of computer security applications, including accurate spam detection, scalable discovery of new malware families, identifying malware download events in vast amounts of web traffic, detecting software exploits, blocking phishing web pages, and preventing fraudulent financial transactions, just to name a few. At the same time, machine learning methods themselves have evolved. In particular, Deep Learning methods have recently demonstrated great improvements over more “traditional” learning approaches on a number of important tasks, including image and audio classification, natural language processing, machine translation, etc. Deep learning has faced an exponential growth over the last decade. Today, it has found use in a wide range of applications, security being one of those. In this project we try to exploit deep learning methodologies to facilitate user authentication on smartphones. Smartphone authentication has explored a variety of domains like iris recognition (latest Samsung Galaxy S8), face recognition (iPhoneX), fingerprints (traditional iPhones), PINs and pattern recognitions (traditional smartphones). In this project, we try to develop a lightweight authentication scheme based on sensor data which continually authenticates the user at regular intervals of time, thus providing greater security.
LoRaWAN-enabled Smart Campus: The Dataset and a People Counter Use Case
Authors: Eldeeb Eslam , Alves Hirley
Published: May 2023

In brief, we present a novel framework that counts the number of people based on the readings of the sensors inside closed rooms. These sensors are connected using LoRa network. First, we identify the transmission failures that cause missing values in the dataset and handle such missing values. In addition, we validate the efficiency of handling the missing values using a long short-term memory (LSTM) architecture that forecast future values based on the handled missing values. Finally, we propose a neural network that formulate the number of people based on the readings. Simulation results show our model achieves an accuracy of 95% in predicting the number of people. We believe that our work would have a significant impact on the road of IoT and wide area network research in wireless communications. Our work could benefit lockdown restrictions during pandemic eras and smart air ventilation systems in smart residual building.

Inflammatory bowel diseases (IBD) include Crohn's disease and ulcerative colitis. IBD represents a pathology that evolves through relapses interspersed with remission. Anemia is the most common extra-intestinal complication in inflammatory bowel disease (IBD). Depending on the hemoglobin level, the anemia is mild, moderate or severe. It can affect quality of life and increase the hospitalization rate of patients. The reported prevalence of anemia in patients with IBD ranges from 6% to 74%. Although the causes of anemia in IBD are multifactorial, iron deficiency anemia remains the most common. Management is based on treating the disease and correcting the anemia with injectable iron. The aim of the work is to take stock of the prevalence and treatment of chronic anemia during IBD, as well as the impact of the covid19 period on the monitoring of this chronic pathology in our structure.

Published: May 2023

Cocoa pod rot (PBK) is the main disease that attacks cocoa pods caused by P. palmivora. Fruit rot disease causes loss of cocoa yield. Cocoa pod rot disease caused by P. palmivora pathogen is not a good and stable control method. One strategy that can be used for control is to develop superior clones tolerant of P. palmivora. Breeding program to obtain P. palmivora tolerant cocoa clones by utilizing cocoa genetic resources derived from potential cultivated clones through detached pot test. The study aimed to obtain cocoa pods tolerant of pod rot using the detached pod test. The research was conducted at the Phytopathology Laboratory of the Department of Plant Pests and Diseases, Faculty of Agriculture, Andalas University. The tested cocoa clones consisted of 6 clones, e.g., Sca 12, TSH 858, ICS 60, GC 7, K TSH 858, and K ICS 60. Cocoa clones were collected from a cocoa plantation owned by PT. Host Sari Lubuk Basuk-Agam Regency. The observed variables related to P. palmivora tolerant cocoa clones were; incubation period, growth of cacao fruit spot area, and color of cocoa beans. The results showed that the TSH 858 and ICS 60 clones had an incubation period of 3 DAI, while the Sca 12, ICS 60, GC 7, K TSH 858, and K ICS 60 clones had an incubation period of 2 DAI. The TSH 858 clone grew 10.82 cm2.day 1, while the ICS 60, GC 7, K. TSH 858 and K. ICS 60 clones grew in spot area, respectively; 11.42, 12.95, 13.24 and 13.58 cm2.day-1. TSH 858 clone has potential as a tolerant clone to P. palmivora attack through detached pod test on fruit.
