Coordinated control of ESC with active front steering and active suspension normal force control for better vehicle’s dynamic response
Authors: Jordanoska V , Changoski V , Danev D 
Published: December 2022

Abstract
Advances in vehicle technologies brought changes into architectures of integration of chassis control systems. Alongside other improvements, integration can provide better vehicle handling, stability and safety. Different chassis control systems can use different control methods. Considering while in motion vehicle has movements in longitudinal, lateral and vertical direction, different control systems target different motion. If there is no coordination among active control systems, interaction and performance conflict can arise. This paper presents coordination of three control systems: electronic stability control (ESC), active front steering control (AFSC) and active suspension normal force control (ASNF). ESC is actually direct yaw and anti-roll control using selective wheel braking. ASNF is considered only on front axle. All systems use fuzzy-logic as a control method. Vehicle is presented as 14-DOF nonlinear full vehicle model and for the control purposes 3-DOF reference model was introduced. Emphasis was given on vehicle parameters characterizing dynamic behavior in longitudinal and lateral direction. Benefits of coordinated action of the three systems can be seen from the results gained through simulation of cornering event and single lane change in Matlab/Simulink. Coordinated control adds to the action of ESC itself, resulting in improved stability and handling, and thus safety of the vehicle.

Published: December 2022

Abstract
From the aspect of traffic safety, the brake system is one of the most important systems. For all exploitation conditions, for which vehicles are projected, and for loads in prescribed boundaries, no matter to the vehicle speed, it is important, for the brake system to be reliable and to provide a very fast stop, or speed adjustment to road conditions. During the stop or during the speed adjustment it comes to the disc brakes temperature increment. So, because of this, the experimental investigations were conducted, in order to determine final values of the temperature for multiple braking processes until stop. In this paper, were conducted two experimental tests for the same vehicle, but for different speeds, which were 60 km/h and 80 km/h, while the other parameters (initial temperature, the mass of the simulated vehicle, number of repetitions) were the same for both tests. The conclusion is that by increment of the speed, rises the necessary time to stop the simulated vehicle, and by this, rises and the stopping distance. Also, rises and the temperature of the disc brake, with the increment of the vehicle speed.
Improving vehicle dynamics employing individual and coordinated sliding mode control in vehicle stability, active front wheel steering and active rear wheel steering systems in co-simulation environment
Authors: Changoski V , Gjurkov I , Jordanoska V 
Published: December 2022

Abstract
The goal for the future, safer and more sustainable transportation leads to implementation of many advanced systems in vehicles. In this paper, a vehicle model with stability control system that uses the braking system is regarded as a base active vehicle. Two alternative vehicle models are considered where this system is combined and integrated with active front wheel steering (AFS) and active rear wheel steering (ARS) system, separately. For the purpose of this research, 3D virtual vehicle models based on a B-segment vehicle were created in ADAMS/Car. As a research tool, a co-simulation approach between ADAMS/Car and MATLAB/Simulink was used. Several sliding mode controllers (SMC) have been proposed and implemented in MATLAB/Simulink in order to analyse the potential improvements of the vehicle dynamics due to the integration and coordination of these systems. In the same MATLAB/Simulink environment, a reference 2DOF nonlinear bicycle model was used. The vehicle models were simulated in driving scenarios based on standardized ISO 7401 test procedures. The scenarios include situations where the passive vehicle loses its stability or fails to complete the manoeuvre while the vehicles with stability control or integrated control systems successfully complete it.

Published: December 2022

Abstract
Space-time and time-varying metastructures have attracted a lot of research interest in recent years. On the other hand, digital programmable metasurfaces have also gained great attention owing to their powerful capabilities in controlling electromagnetic (EM) fields and waves in real time, which is very suitable for implementing spatiotemporal modulations in a digital manner. Accordingly, space-time-coding (STC) digital metasurfaces have recently been proposed to realize advanced manipulations of EM wavefronts and digital information, allowing simultaneous control of propagation directions in the space domain and harmonic distributions in the frequency domain. However, their instantaneous responses and the connection between the time- and frequency-domain characteristics have not yet been fully revealed. Here, we present a joint time-frequency analysis method to revisit STC digital metasurfaces, in which the time-domain instantaneous scattering patterns and frequency-domain equivalent excitations are investigated to analyze the spatial-spectral distributions of the modulated waves. This joint time-frequency analysis method helps to better explain the basic working principle of STC digital metasurfaces and is expected to facilitate more applications in wireless communications, radar, imaging, and beamforming.

Abstract
Spiking neural networks (SNNs) are gaining attention due to their energy-efficient computing ability, making them relevant for implementation on low-power neuromorphic hardware. Their biological plausibility has permitted them to benefit from unsupervised learning with bio-inspired plasticity rules, such as spike timing-dependent plasticity (STDP). However, standard STDP has some limitations that make it challenging to implement on hardware. In this paper, we propose a convolutional SNN (CSNN) integrating single-spike integrate-and-fire (SSIF) neurons and trained for the first time with voltage-dependent synaptic plasticity (VDSP), a novel unsupervised and local plasticity rule developed for the implementation of STDP on memristive-based neuromorphic hardware. We evaluated the CSNN on the TIDIGITS dataset, where, helped by our sound preprocessing pipeline, we obtained a performance better than the state of the art, with a mean accuracy of 99.43%. Moreover, the use of SSIF neurons, coupled with time-to-first-spike (TTFS) encoding, results in a sparsely activated model, as we recorded a mean of 5036 spikes per input over the 172 580 neurons of the network. This makes the proposed CSNN promising for the development of models that are extremely efficient in energy. We also demonstrate the efficiency of VDSP on the MNIST dataset, where we obtained results comparable to the state of the art, with an accuracy of 98.56%. Our adaptation of VDSP for SSIF neurons introduces a depression factor that has been very effective at reducing the number of training samples needed, and hence, training time, by a factor of two and more, with similar performance.

Introducing a Real-Time Method for Identifying the Predictors of Noncompliance with Event-Based Reporting of Tobacco Use in Ecological Momentary Assessment
Authors: Kendall Ashley D , Robinson Charles S H , Diviak Kathleen R , Hedeker Donald , Mermelstein Robin J 
Published: December 2022

AbstractBackgroundLittle is known about the factors that bias event-based (i.e., self-initiated) reporting of health behaviors in ecological momentary assessment (EMA) due to the difficulty inherent to tracking failures to self-initiate reports.PurposeTo introduce a real-time method for identifying the predictors of noncompliance with event-based reporting.MethodsN = 410 adults who used both cigarettes and e-cigarettes completed a 1-week EMA protocol that combined random reporting of current contexts with event-based reporting of tobacco use. Each random assessment first asked if participants were currently using tobacco and, if so, the assessment converted into a “randomly captured” event report—indicating failure to self-initiate that report. Multilevel modeling tested predictors of failing to complete random reports and failing to self-initiate event reports.ResultsOn the person level, male sex, higher average cigarette rate, and higher average cigarette urge each predicted missing random reports. The person-level predictors of failing to self-initiate event reports were older age, higher average cigarette and e-cigarette rates, higher average cigarette urge, and being alone more on average; the moment-level predictors were lower cigarette urge, lower positive affect, alcohol use, and cannabis use. Strikingly, the randomly captured events comprised more of the total EMA reports (28%) than did the self-initiated event reports (24%). These report types were similar across most variables, with some exceptions, such as momentary cannabis use predicting the random capture of tobacco events.ConclusionsThis study demonstrated a method of identifying predictors of noncompliance with event-based reporting of tobacco use and enhancing the real-time capture of events.
Recent advances in the regulation of root parasitic weed damage by strigolactone-related chemicals
Authors: Ito Shinsaku 
Published: December 2022

ABSTRACTRoot parasitic weeds such as Striga spp. and Orobanche spp. dramatically reduce the yields of important agricultural crops and cause economic losses of over billions of US dollars worldwide. One reason for the damage by root parasitic weeds is that they germinate after specifically recognizing the host cues, strigolactones (SLs). SLs were identified ˃50 years ago as germination stimulants for root parasitic weeds, and various studies have been conducted to control parasitic weeds using SLs and related chemicals. Recently, biochemical and molecular biological approaches have revealed the SL biosynthesis and SL receptors; using these findings, various SL-related chemicals have been developed. This review summarizes recent research on SLs and their related chemicals for controlling root parasitic weeds.

ABSTRACTBackgroundKt/Vurea is the most used marker to estimate dialysis adequacy; however, it does not reflect the removal of many other uraemic toxins, and a new approach is needed. We have assessed the feasibility of estimating intradialytic serum time-averaged concentration (TAC) of various uraemic toxins from their spent dialysate concentrations that can be estimated non-invasively online with optical methods.MethodsSerum and spent dialysate levels and total removed solute (TRS) of urea, uric acid (UA), indoxyl sulphate (IS) and β2-microglobulin (β2M) were evaluated with laboratory methods during 312 haemodialysis sessions in 78 patients with four different dialysis treatment settings. TAC was calculated from serum concentrations and evaluated from TRS and logarithmic mean concentrations of spent dialysate (MlnD).ResultsMean (± standard deviation) intradialytic serum TAC values of urea, UA, β2M and IS were 10.4 ± 3.8 mmol/L, 191.6 ± 48.1 µmol/L, 13.3 ± 4.3 mg/L and 82.9 ± 43.3 µmol/L, respectively. These serum TAC values were similar and highly correlated with those estimated from TRS [10.5 ± 3.6 mmol/L (R2 = 0.92), 191.5 ± 42.8 µmol/L (R2 = 0.79), 13.0 ± 3.2 mg/L (R2 = 0.59) and 82.7 ± 40.0 µmol/L (R2 = 0.85)] and from MlnD [10.7 ± 3.7 mmol/L (R2 = 0.92), 191.6 ± 43.8 µmol/L (R2 = 0.80), 12.9 ± 3.2 mg/L (R2 = 0.63) and 82.2 ± 38.6 µmol/L (R2 = 0.84)], respectively.ConclusionsIntradialytic serum TAC of different uraemic toxins can be estimated non-invasively from their concentration in spent dialysate. This sets the stage for TAC estimation from online optical monitoring of spent dialysate concentrations of diverse solutes and for further optimization of estimation models for each uraemic toxin.

Abstract
Bacterial membrane vesicles (MVs) are abundant in the oceans, but their potential functional roles remain unclear. In this study we characterized MV production and protein content of six strains of Alteromonas macleodii, a cosmopolitan marine bacterium. Alteromonas macleodii strains varied in their MV production rates, with some releasing up to 30 MVs per cell per generation. Microscopy imaging revealed heterogenous MV morphologies, including some MVs aggregated within larger membrane structures. Proteomic characterization revealed that A. macleodii MVs are rich in membrane proteins related to iron and phosphate uptake, as well as proteins with potential functions in biofilm formation. Furthermore, MVs harbored ectoenzymes, such as aminopeptidases and alkaline phosphatases, which comprised up to 20% of the total extracellular enzymatic activity. Our results suggest that A. macleodii MVs may support its growth through generation of extracellular ‘hotspots’ that facilitate access to essential substrates. This study provides an important basis to decipher the ecological relevance of MVs in heterotrophic marine bacteria.
Inventorship Standards, Joint Inventorship and Procedures in Inventorship Disputes in U.S. Patent Law and German Patent Law
Authors: Gotthardt Lukas 
Published: December 2022

Abstract
This article deals with the standard for assessing joint inventorship in German and U.S. patent law, which is of great importance given the strong legal position that is assigned to each joint inventor as co-owner of a patent issued as a result. The article explains the criteria used by German and U.S. courts to determine whether a person is to be viewed as a joint inventor. It also deals with the remedies available to affected parties who want to defend themselves against an incorrect determination of joint inventorship. Both jurisdictions have established a similar approach to determine joint inventorship by examining the quality of the respective contributions to the invention of each possible joint inventor. The German and U.S. courts have established a low bar for granting joint inventorship status that risks assigning far-reaching legal powers to a large number of persons. In contrast to the similarities in substantive law, the remedies available are rather different in the two jurisdictions. The article concludes with a proposal for limiting the excessively broad joint inventorship standard by redefining the criterion of collaboration, which is considered an essential element of joint inventorship in both jurisdictions but has received little attention in judicial practice.
Chicosciencea Bochini, Cunha, Terossi & Almeida, 2020 is a junior subjective synonym of Microprosthema Stimpson, 1860 (Decapoda: Stenopodidea: Spongicolidae)

Published: December 2022

Abstract
A review of the morphological and phylogenetic characters of the genus ChicoscienceaBochini, Cunha, Terossi & Almeida, 2020 (Stenopodidea: Macromaxillocarididae) shows that the taxon is not a new and valid genus, and the taxon must be considered a junior subjective synonym of MicroprosthemaStimpson, 1860. All diagnostic morphological characters given for the genus are found in numerous species of Microprosthema, as well as in other genera and species of stenopodids. The molecular phylogeny proposed as part of the description of Chicosciencea is inconclusive based on the support values.

Abstract
Morgagni hernia is a rare form of diaphragmatic hernia. It is located at the anterior edge of the diaphragm and does not have an anterior rim. It is difficult to achieve a secure closure and maintain the tension of closure with laparoscopic surgery. We have performed laparoscopic resection of colorectal cancer and hernia repair simultaneously. An 89-year-old woman underwent laparoscopic hernia repair and ileocecal resection simultaneously. Regarding hernia repair, we considered that it would be difficult to use a mesh from the viewpoint of infection due to the colectomy. Therefore, we have done the extra-abdominal suture method. After laparoscopic ileocecal resection, a small incision was made in the epigastric region, and Morgagni hernia repair was performed with extra-abdominal sutures. She had no recurrence of either colon cancer or hernia for 22 months post-operatively. The extra-abdominal suture method can provide secure closure of the hernia orifice for Morgagni hernia.
Oesophageal neuroendocrine tumours—case series of a rare malignancy
Authors: Nikolic Amanda L , Gullifer James , Johnson Mary Ann , Hii Michael W 
Published: December 2022

Abstract
Oesophageal neuroendocrine neoplasms (NENs) are rare tumours. Neuroendocrine carcinomas (NECs) are the highest grade of NENs, with aggressive biological behaviour and poor outcomes. No standardized treatment pathways exist for these tumours, with management being individualized based on patient and tumour factors. We present five cases, four men and one women between 63 and 68 years old, who were diagnosed with symptomatic primary oesophageal NECs. Three were diagnosed with localized disease, and two were diagnosed with metastatic disease. Endoscopy, biopsy and staging scan results are outlined. Two patients received neoadjuvant chemotherapy. Three patients with localized disease underwent oesophagectomy. Two of these patients received neoadjuvant chemotherapy. Four patients have succumbed to their disease, with a median survival following a diagnosis of 18 months (5–34 months). This case series highlights the variability of presentation and stage at diagnosis of oesophageal NECs. Multimodal treatment is commonly utilized; however, outcomes are universally poor. Further research is required to determine the optimal treatment regimen for oesophageal NENS.

Abstract
Carotid body tumors (CBTs) are a neoplasm that affects the carotid glomus. This study aims to improve the management of CBTs in Ecuador. This single-center, retrospective observational study was conducted at the Instituto de la Tiroides y Enfermedades de Cabeza y Cuello (ITECC). We included adults with CBTs, between January 2019 and August 2022. A total of 15 patients with CBTs were included. All patients were females living at high altitudes (&gt;2500 m). In the Shamblin classification, 12 tumors were type II, and 3 were type III. Complete tumor resection was performed in all patients without pre-operative embolization. All patients had benign CBTs with a mean follow-up of 17, 73 months. In a time when the medical cost is high mainly in low-income countries such as Ecuador, further investigation should be undertaken in the form of randomized prospective trials to answer who would benefit from the pre-TAE procedure.
Reassessment of Critical Anti-D Antibody Titer in RhD Alloimmunized Antenatal Women

Published: December 2022

AbstractObjectiveIn the setting of RhD-alloimmunized pregnancy, laboratory variations in critical titer (CT) of anti-D antibody may result in needless referrals or a compromised fetal outcome.MethodsRhD-alloimmunized pregnant women were included. Fetal outcome was categorized based on cord hemoglobin and interventions required. For 3 commonly used CTs of 8, 16, and 32, sensitivity and specificity as well as positive and negative predictive values were computed.ResultsWhen compared with CTs of 16 and 32, we detected 6.9% and 19.4% more cases of moderate-severe hemolytic disease of the fetus and newborn by using 8 as the CT. However, this leads to greater rate of unnecessary referral (12.1%, 10/82) than a CT of 16 (8.2%, 6/73) and 32 (4.9%, 3/61). A CT of 8 demonstrated 100% sensitivity, but 12.1% (10/82) of patients were referred needlessly.ConclusionBecause of its 100% sensitivity, we advocate decreasing the CT to 8. However, this may lead to unwarranted referrals.
