Versatile Robotic Workstation for Electronic Skin - Problems and Solutions
Authors: Klimaszewski Jan 
Published: July 2023

AbstractIn the face of the Fourth Industrial Revolution (Industry 4.0), collaborative robots have become one of the key pillars of development. Thanks to their sensors, they allow increased flexibility and safety while working in a shared space with humans. One such sensor is the electronic skin (e-skin), which enhances human-robot collaboration through physical contact. This paper presents the developed versatile robotic workstation that allows, among other things, the calibration of e-skin touch measurements. In particular, the problems encountered with the use of a standard industrial robot are presented and ways to solve them are discussed. The presented approach allows the automatic acquisition of calibration measurements of e-skin sensors within the reach of the robot.

Published: July 2023

AbstractThe following paper introduces a new way of presenting the results of engineering simulations. The object of consideration is the motion of the snake robot on a flat surface. The robot’s trajectory and control signals are calculated in MATLAB. Different approaches have been presented to show how the robot moves - from 2D plots and 3D animations observed from a computer screen to realistic visualisations displayed in the Virtual Reality headset. The proposed VR simulation will allow watching the simulation results and manipulating simulation parameters from inside of VR.

Authors: Matys-Popielska Katarzyna , Popielski Krzysztof , Sibilska-Mroziewicz Anna 
Published: July 2023

AbstractStroke is the second cause of mortality and one of the leading causes of disability in adults. Post-stroke complications involve many different systems through which they involve difficulties in daily life. A very common complication that involves about 25–30% of post-stroke patients is spatial neglect syndrome, which involves the impaired perception of one’s body and space. An important aspect of treatment for stroke patients is rehabilitation, both while still in the hospital and later in rehabilitation facilities as well as at home. Many studies have shown effective virtual reality (VR)-based general therapy systems after stroke. In particular, systems for motor function rehabilitation. In the following paper, a game proposal for the rehabilitation of patients with unilateral spatial neglect syndrome is shown. This game takes into account the specific perception and special motor skills of patients with spatial neglect syndrome. The described game was presented to a team of rehabilitation specialists working at the Department of Neurology and Stroke Unit of the University Clinical Hospital in Białystok and was evaluated by these specialists.
Representation of Observations in Reinforcement Learning for Playing Arcade Fighting Game
Authors: Du Huaiyu , Jóźwiak Rafał 
Published: July 2023

AbstractReinforcement learning (RL) is one of three basic machine learning paradigms, alongside supervised learning and unsupervised learning. Reinforcement learning algorithms have become very popular in simple computer games and games like chess and GO. However, playing classical arcade fighting games would be challenging because of the complexity of the command system (the character makes moves according to the sequence of input) and combo system. In this paper, a creation of a game environment of The King of Fighters ’97 (KOF ’97), which implements the open gym env interface, is described. Based on the characteristics of the game, an innovative approach to represent the observations from the last few steps has been proposed, which guarantees the preservation of Markov’s property. The observations are coded using the “one-hot encoding” technique to form a binary vector, while the sequence of stacked vectors from successive steps creates a binary image. This image encodes the character’s input and behavioural pattern, which are then retrieved and recognized by the CNN network. A network structure based on the Advantage Actor-Critic network was proposed. In the experimental verification, the RL agent performing basic combos and complex moves (including the so-called “desperation moves”) was able to defeat characters using the highest level of AI built into the game.

Authors: Chakraborty Somenath , Murali Beddhu 
Published: July 2023

AbstractThe ongoing terrifying wave of COVID-19 which is caused by the Severe Acute Respiratory Syndrome Coronavirus 2 or SARS-CoV-2 continues to affect human life and disrupt healthcare systems. Chest computed tomography (CT) is an effective clinical tool for estimating the patient’s severity levels and deciding appropriate treatment regimes. In this paper, we use a deep learning method for detecting COVID-19 using chest CT images with the more advanced balanced dataset. We used a dataset of 8054 real patient CT scans, of which 5427 had COVID-19 and 4223 were Non-COVID-19 patient images. Our model had an average detection accuracy of 91.96% on the test dataset. In conclusion, Automated Deep Learning (DL) methodologies allow for speedy evaluation of CT images to detect COVID-19.

Cyclic Lattices, Ideal Lattices, and Bounds for the Smoothing Parameter

AbstractCyclic lattices and ideal lattices were introduced by Micciancio (2002), Lyubashevsky and Micciancio (2006), respectively, which play an efficient role in Ajtai’s construction of a collision resistant Hash function (see Ajtai (1996), Ajtai and Dwork (1997)) and in Gentry’s construction of fully homomorphic encryption (see Gentry (2009)).

, nor exhibit the relationship of cyclic lattices and ideal lattices. In this chapter, we regard the cyclic lattices and ideal lattices as the correspondences of finitely generated R-modules, so that we may show that ideal lattices are actually a special subclass of cyclic lattices, namely, cyclic integer lattices. In fact, there is a one to one correspondence between cyclic lattices in $$\mathbb {R}^n$$

and finitely generated R-modules (see Theorem 4). On the other hand, since R is a Noether ring, each ideal of R is a finitely generated R-module, so it is natural and reasonable to regard ideal lattices as a special subclass of cyclic lattices (see Corollary 7). It is worth noting that we use a more general rotation matrix here, so our definition and results on cyclic lattices and ideal lattices are more general forms. As an application, we provide a cyclic lattice with an explicit and countable upper bound for the smoothing parameter (see Theorem 5). It is an open problem that is the shortest vector problem on cyclic lattice NP-hard (see Micciancio (2002)). Our results may be viewed as a substantial progress in this direction.

Published: July 2023

AbstractHyperplasia of the pharyngeal tonsils is to be considered pathologic when nasopharyngeal symptoms of mechanical obstruction and/or chronic inflammation occur. Chronic Eustachian tube dysfunction can result in various middle ear diseases such as conductive hearing loss, cholesteatoma, and recurrent acute otitis media. During examination, attention should be paid to the presence of adenoid facies (long face syndrome), with a permanently open mouth and visible tip of the tongue. In the case of severe symptoms and/or failure of conservative treatment, adenoidectomy is usually performed on an outpatient basis. Conventional curettage remains the established standard treatment in Germany. Histologic evaluation is indicated for clinical evidence of mucopolysaccharidoses. Due to the risk of hemorrhage, the preoperative bleeding questionnaire, which is obligatory before every pediatric surgery, is referred to. Recurrence of adenoids is possible despite correct adenoidectomy. Before discharge home, otorhinolaryngologic inspection of the nasopharynx for secondary bleeding should be performed and anesthesiologic clearance obtained.

ZusammenfassungFür motorisch inkomplette Querschnittgelähmte ist eine Verbesserung der Gehfunktion ein wichtiges Ziel im Rehabilitationsprogramm. In den spezialisierten Behandlungszentren dienen der 6‑Minuten-Gehtest, der 10-Meter-Gehtest oder der „Timed-up-and-go“-Test als standardisiertes Messinstrument zur Erfassung der Gehfähigkeit. Diese Tests sind jedoch nicht in der Lage, die Qualität des Gehens zu beurteilen. Mithilfe der markerbasierten Bewegungsanalyse kann das Gangbild reliabel erfasst und die Qualität der Bewegung beurteilt werden. Dies ermöglicht eine objektive Bewertung der Gangqualität über den Verlauf der Jahre oder kann unterstützend für die Therapieplanung eingesetzt werden. Am Beispiel von zwei Fällen wird der Nutzen einer solchen Analyse vorgestellt.

Published: July 2023

AbstractClonidine has various clinical effects mediated by agonism of α1- or α2-adrenoceptors and the blocking of hyperpolarization-activated-nucleotide-gated pacemaker channels (HCN). It is unknown whether clonidine can also stimulate human cardiac histamine H2 receptors (hH2Rs). We used isolated electrically stimulated left and spontaneously beating right atrial preparations from mice overexpressing the hH2R specifically in the heart (H2-TG), and spontaneously beating right atrial preparations of guinea pigs for comparison. Moreover, we studied isolated electrically stimulated muscle strips from the human right atrium. Clonidine (1, 3, and 10 µM) increased force of contraction in isolated left atrial preparations from H2-TG mice. In contrast, clonidine reduced the spontaneous beating rate in right atrial preparations from H2-TG. Clonidine raised the beating rate in guinea pig right atrial preparations. Clonidine failed to increase the force of contraction but reduced beating rate in wild-type litter mate mice (WT). In WT, histamine failed to increase the force of contraction in left atrial preparations and beating rate in right atrial preparations. Clonidine (10 µM) increased the force of contraction in isolated human right atrial preparations. The positive inotropic effect in the human atrium was attenuated by cimetidine (10 µM). Clonidine increased the beating rate of the isolated spontaneously beating guinea pig right atrium and acted as a H2R partial agonist. Furthermore, clonidine showed binding to the guinea pig H2R (100 µM) using HEK cells in a recombinant expression system (pKi < 4.5) but hardly to the human H2R. These data suggest that clonidine can functionally activate cardiac human H2R.

AbstractMicroorganisms are the most diverse life form on the planet and are critical for maintaining the geochemical cycles, especially in extreme environments. Bacterial communities are dynamic and respond directly to changes in abiotic conditions; among these communities, poly-extremophiles are particularly sensitive to perturbations due to their high specialization. Salar de Huasco is a high-altitude wetland located on the Chilean Altiplano exhibiting several conditions considered extreme for life, including negative water balance, extreme variations in temperature and pH values, high UV radiation, and the presence of various toxic metal(oids). However, previous reports have revealed a diverse bacterial community that has adapted to these conditions, here, we aimed to determine whether microbial community diversity and composition changed in response to geographical and seasonal variations. We found that there are significant differences in diversity, abundance, and composition in bacterial taxa that could be attributed to local geographical and seasonal variations, which in turn, can be associated with microbial traits. In conclusion, in this poly-extreme environment, small-scale changes can trigger significant changes in the microbial communities that maintain basic biogeochemical cycles. Further in depth analysis of microbial functionality and geo-ecological dynamics are necessary to better understand the relationships between seasonal changes and bacterial communities.
A Review on Microbial Species for Forensic Body Fluid Identification in Healthy and Diseased Humans
Authors: Dass Mishka , Singh Yashna , Ghai Meenu 
Published: July 2023

AbstractMicrobial communities present in body fluids can assist in distinguishing between types of body fluids. Metagenomic studies have reported bacterial genera which are core to specific body fluids and are greatly influenced by geographical location and ethnicity. Bacteria in body fluids could also be due to bacterial infection; hence, it would be worthwhile taking into consideration bacterial species associated with diseases. The present review reports bacterial species characteristic of diseased and healthy body fluids across geographical locations, and bacteria described in forensic studies, with the aim of collating a set of bacteria to serve as the core species-specific markers for forensic body fluid identification. The most widely reported saliva-specific bacterial species are Streptococcus salivarius, Prevotella melaninogenica, Neisseria flavescens, with Fusobacterium nucleatum associated with increased diseased state. Lactobacillus crispatus and Lactobacillus iners are frequently dominant in the vaginal microbiome of healthy women. Atopobium vaginae, Prevotella bivia, and Gardnerella vaginalis are more prevalent in women with bacterial vaginosis. Semen and urine-specific bacteria at species level have not been reported, and menstrual blood bacteria are indistinguishable from vaginal fluid. Targeting more than one bacterial species is recommended for accurate body fluid identification. Although metagenomic sequencing provides information of a broad microbial profile, the specific bacterial species could be used to design biosensors for rapid body fluid identification. Validation of microbial typing methods and its application in identifying body fluids in a mixed sample would allow regular use of microbial profiling in a forensic workflow.

Abstract
Purpose
Whether beverage quality affects changes in glycaemic traits and type 2 diabetes (T2D) risk is unknown. We examined associations of a previously developed Healthy Beverage Index (HBI) with insulin resistance, and risk of prediabetes and T2D.

Methods
We included 6769 participants (59% female, 62.0 ± 7.8 years) from the Rotterdam Study cohort free of diabetes at baseline. Diet was assessed using food-frequency questionnaires at baseline. The HBI included 10 components (energy from beverages, meeting fluid requirements, water, coffee and tea, low-fat milk, diet drinks, juices, alcohol, full-fat milk, and sugar-sweetened beverages), with a total score ranging from 0 to 100. A higher score represents a healthier beverage pattern. Data on study outcomes were available from 1993 to 2015. Multivariable linear mixed models and Cox proportional-hazards regression models were used to examine associations of the HBI (per 10 points increment) with two measurements of HOMA-IR (a proxy for insulin resistance), and risk of prediabetes and T2D.

Results
During follow-up, we documented 1139 prediabetes and 784 T2D cases. Mean ± SD of the HBI was 66.8 ± 14.4. Higher HBI score was not associated with HOMA-IR (β: 0.003; 95% CI − 0.007, 0.014), or with risk of prediabetes (HR: 1.01; 95% CI 0.97, 1.06), or T2D (HR: 1.01; 95% CI 0.96, 1.07).

Conclusion
Our findings suggest no major role for overall beverage intake quality assessed with the HBI in insulin resistance, prediabetes and T2D incidence. The HBI may not be an adequate tool to assess beverage intake quality in our population.
Bridging the gap between decomposition theory and forensic research on postmortem interval

Published: July 2023

AbstractKnowledge of the decomposition of vertebrate animals has advanced considerably in recent years and revealed complex interactions among biological and environmental factors that affect rates of decay. Yet this complexity remains to be fully incorporated into research or models of the postmortem interval (PMI). We suggest there is both opportunity and a need to use recent advances in decomposition theory to guide forensic research and its applications to understanding the PMI. Here we synthesise knowledge of the biological and environmental factors driving variation in decomposition and the acknowledged limitations among current models of the PMI. To guide improvement in this area, we introduce a conceptual framework that highlights the multiple interdependencies affecting decay rates throughout the decomposition process. Our framework reinforces the need for a multidisciplinary approach to PMI research, and calls for an adaptive research cycle that aims to reduce uncertainty in PMI estimates via experimentation, modelling, and validation.
Error analysis of measurement uncertainty: a snapshot literature review in field of medicine and health in China
Authors: Nie Manqing , Chen Jing , Zheng Bo 
Published: July 2023

AbstractTo analyze and statistically compare common errors in the evaluation of measurement uncertainty in medicine and health field, using literature research and comparison with national standards, in order to understand the current status of measurement uncertainty evaluation in the medicine and health field. Using Chinese National Knowledge Infrastructure (CNKI) as the sample population, Stratified Proportional Sampling (PPS) was used to extract journal articles related to measurement uncertainty in the field of medicine and health. The articles were compared with the Eurachem/CITAC Guide QUAM to analyze measurement uncertainty errors. Academic attention to measurement uncertainty in the field of medicine and health in the CNKI literature database has shown explosive growth since 2005. Seven common errors in measurement uncertainty evaluation were identified. None of the 30 journal articles analyzed were error-free, with a total error rate of 44 %. The error rate for ignorance of blank uncertainty was 87 %, improper evaluation of standard curve was 67 %, improper significant figures were 60 %, and insufficient information for Type B evaluation was 50 %. The error rate for provincial and higher-level institutions was 48 %, while the error rate for institutions below the provincial level was 43 %. The difference between the two error rates was not statistically significant (p = 0.523). There is an urgent need to improve the rationality of measurement uncertainty evaluation in medicine and health field, and to strengthen the education and academic communication through national and international cooperation.

Published: July 2023

AbstractThe establishment of technological approaches for the defluorination of waste fluoropolymers and recovery of eliminated F– may contribute to the development of fluorine recycling routes. In this study, we investigated the effects of alkalinity, phase transfer catalyst (PTC) concentration, reaction temperature, and solvent types on the defluorination of polyvinylidene fluoride (PVDF) by alkaline wet processing. The rate of defluorination of PVDF in 4.0 M sodium hydroxide (NaOH) and 50 mM tetrabutylammonium bromide (TBAB) under aqueous conditions reached 89.2%. In addition, the defluorination reaction proceeded faster in solvents such as diethylene glycol (DEG) and triethylene glycol (TEG) than in water because of the high affinity between PVDF and these diols. To investigate the feasibility of developing a fluorine recycling route, the defluorination of a photovoltaic (PV) backsheet and subsequent CaF2 precipitation from the eliminated F– was examined. A total of 88.3% of F contained in the PV backsheet was recovered as CaF2, which satisfied the quality standards of commercial fluorspar. This study demonstrated that alkaline wet processing is effective for the defluorination of PVDF and that the establishment of a F recycling route along the F supply chain may be feasible.
