Cool- and Warm-Season Turfgrass Irrigation with Subsurface Drip and Sprinkler Methods Using Different Water Management Strategies and Tools
Authors: Orta Abdül Halim , Todorovic Mladen , Ahi Yeşim
Published: January 2023

This study compared the performances of subsurface drip irrigation (SDI) to sprinkler irrigation (SI) of cool-season turf mix (CS) and warm-season (WS) turfgrass species while investigating their response to different irrigation scheduling strategies. Moreover, the suitability of crop water stress index (CWSI) for monitoring water stress and scheduling irrigation was tested. Irrigation was applied up to the field capacity when 30%, 50% and 70% of total available water was consumed. All parameters, including color, quality, fresh yield, dry matter yield, irrigation water productivity, water productivity, vegetation height and mowing, differed significantly for different irrigation methods and water supply strategies for both species. The best visual turf was maintained under non-limiting soil moisture conditions (30%) in all main and sub-treatments. At this irrigation threshold, maximum and minimum amounts of irrigation water were applied in SI CS treatment (523.5 mm) and SDI WS treatment (298.6 mm), respectively. Warm-season turf required up to 40% less water than cool-season turf mix. In the water-scarce regions, 50% treatment for cool-season and 70% treatment for warm-season can be suggested for acceptable visual quality, lower water consumption and less frequent clipping. The mean CWSI before irrigation, representing irrigation threshold, ranged between 0.22–0.70.

Published: January 2023

This study determined the PAH contamination variations in the subtidal surface sediment with oil fingerprinting in the Wu Yi San oil spill in Yeosu, Korea, in January 2014. The ∑16 PAHs and ∑alkyl PAHs were investigated in surface sediment and seawater 1 month after the oil spill for 1 year at 3-month intervals in the accident (St. A-F) and adjacent areas (St. 1-20). The averaged ∑16 PAHs and ∑alkyl PAH concentration in the five samplings were 42.2–171.7 ng/g and 211.5–221.8 ng/g, respectively. Comparing the PAH levels in St.E and St.17 indicated a decreased tendency, from 357.9 to 31.1 ng/g dw. in ∑16 PAHs, and from 1900.9 to 211.5 ng/g dw. in ∑alkyl PAHs. The PAHs were not statically correlated between surface sediment and seawater (p > 0.05), implying that the fate of PAHs was rapidly dispersed toward adjacent coasts and beaches. Pyrogenic origin was predominant in 16 PAHs, and petrogenic origin in alkylated PAHs. Notably, C2-D/C2-P and C3-D/C3-P ratios in the accident area during the first sampling were similar to accident oil, but the similarity was not shown in other samplings. Only the C2-naphthalene (St.A), C1-phenanthrene (St.A and St.B), and C2-phenanthrene (the entire accident area points) concentrations were higher than the ERL SQG.
Regenerative Braking Strategy of Dual-Motor EV Considering Energy Recovery and Brake Stability
Authors: Wu Tonglie , Wang Feng , Ye Peng
Published: January 2023

The dual-motor EV (Electric Vehicle) is increasingly favored by manufacturers for its excellent performance in terms of power and economy. How to further reduce its energy consumption and make full use of the dual-motor energy recovery is an important support to improve the overall vehicle economy and realize the “dual carbon” strategy. For the dual-motor EV architecture, the motor model, power battery loss model and vehicle longitudinal braking force model are established and the energy recovery-dominated regenerative braking torque distribution (RBD) rule of the dual motors is designed. Based on genetic algorithm (GA) theory and taking into account SOC, vehicle speed and braking intensity, a regenerative-braking torque optimization method is proposed that integrates energy recovery and braking stability. The braking intensity of 0.3 and the initial vehicle speed of 90 km/h are selected for verification. Compared with the rule method, the energy recovery and stability are improved by 22.8% and 4.8%, respectively, under the genetic algorithm-based and energy recovery-dominated regenerative-braking torque distribution (GA-RBD) strategy. A variety of conditions are selected for further strategy validation and the result shows that compared with the rule-based method, both energy recovery and braking stability are improved as braking speed and braking intensity increase under the GA-RBD strategy.

Toxoplasma gondii is a zoonotic parasite globally infecting a wide range of species, including humans. Felids are the only known hosts that can excrete environmentally resistant oocysts into ecosystems. In boreal regions, Canada lynx (Lynx canadensis) are sought by hunters primarily for their fur, and they are occasionally eaten. We examined carcasses salvaged from trappers from boreal regions of eastern (n = 97) and western (n = 357) Canada. We detected T. gondii antibodies in fluid from thawed heart tissue using an enzyme-linked immunosorbent assay, DNA in brain and heart via magnetic capture and real-time PCR assay, and presence of DNA in feces using a real-time PCR with melt curve analysis. We detected antibodies against T. gondii and DNA in tissues in 24% and 19% of lynx, respectively. One lynx was positive for DNA of T. gondii in feces, which could indicate intestinal infection and potential for shedding oocysts. Our results indicate that lynx may be a useful sentinel species for monitoring environmental circulation of T. gondii in northern boreal regions and may pose a risk for transmission to other wildlife and to people handling or consuming lynx.
Genealogy and Phenomenology of Fascism.
Authors: Breschi Danilo
Published: January 2023

Without reconstructing its genealogy, which then means its history, a political-ideological phenomenon such as fascism, of which Italy was the firstborn between the 1910s and 1920s, can never be fully understood. Its history already provides, at least in part, the interpretation, and in any case helps to understand the phenomenon. Genealogy and phenomenology are therefore the type of analysis that we will conduct in the following pages to scientifically understand a phenomenon too often loaded with public use and exploited for political purposes both in a negative and a positive key. Always and in any case polemogenic.
La notion de conciliation de la vie professionnelle et de la vie familiale : révolution temporelle ou métaphore des discriminations ?
Authors: Junter-Loiseau Annie
Published: January 2023

D’où vient cet engouement pour la conciliation entre la vie professionnelle et la vie privée qui envahit les politiques publiques communautaires et nationales de l’emploi, de la famille ? Derrière la formule « prête à penser », quelles sont les mesures mises en œuvres par les acteurs publics, économiques et sociaux pour harmoniser les deux univers de la famille et du travail ? À partir d’une analyse des usages de la notion de conciliation dans les textes communautaires et nationaux et de son emploi dans les conventions et accords collectifs de travail, l’auteure suggère que la conciliation procède moins d’une révolution dans l’approche des temps sociaux que d’une nouvelle manière de nommer les inégalités temporelles entre les femmes et les hommes dans la famille et le travail. Loin d’être une révolution temporelle, elle serait une métaphore des discriminations.
L’embryon en suspens
Authors: Bateman Simone , Salem Tania
Published: January 2023

Cet article part d’un fait divers où les principaux protagonistes s’affrontent sur le sort à réserver à des embryons conçus in vitro et congelés, suite à la mort du conjoint de la femme traitée. Le cas est présenté comme paradigme de la procréation assistée. Il souligne la radicale transformation du contexte dans lequel parents, médecins et scientifiques ont à prendre des décisions sur des embryons et fait émerger la redistribution de pouvoir et de responsabilités entre protagonistes que cette transformation implique. Une comparaison des éléments de ce fait divers avec les paramètres de prise de décision établis dans la loi sur l’interruption de grossesse (1975) révèle l’importance déterminante, pour la définition de la situation et pour la compréhension du conflit, de la localisation physique de l’embryon (dans ou hors du corps de la femme).
Techniques et acteurs : parcours différenciés de femmes dans une démarche de fécondation in vitro
Authors: Tain Laurence
Published: January 2023

The analysis between those involved in new reproductive technology has often led to highlighting the strategies of those who are considered dominant : inventors, doctors, men. Here on the other hand we study the experience of women, making the hypothesis that there are differences in the search for medically-assisted reproduction reflecting the complexity of gender relations. Indeed, analysing women’s trajectories on the basis of the medical records of a specialized hospital service reveal specific forms of behaviour : thus we see different strategies depending on the professional situation, the level of education, the position in relation to the hospital. With the growing medicalization of our society, the « duty to reproduce » is carried out on a stage in which gender relations, the relationship to work and the link to the medical institution are all factors to be considered.
Les paradoxes des droits reproductifs au Brésil : avortement et stérilisation féminine
Authors: Scavone Lucila
Published: January 2023

This article explains the debate in Brazil around reproductive rights and underlines the advances and specific contradiction of two problems which are the current lot of Brazilian women : sterilization and illegal abortions. It highlights the fact that the gernalized practice of female sterlization and the number of backstreet abortions, which are a risk to women’s health, reveal the failings of health policy at the level of reproductive choice and the population control policy. It shows the different directions taken by this discussion at the end of the 1990s and the need to reappropriate its dynamic of social transformation.
Contraception masculine et querelles de genre
Authors: Oudshoorn Nelly
Published: January 2023

Since the Second World War, thirteen new contraceptives for women have been developed while the major methods of contraception available to men do not differ from those available to men over 400 years ago. Thus, responsibility for contraception and its risks to health is delegated primarily to women, not to men. This paper seeks to explore the role of different actors in rewriting this gender script. Special attention will be paid to how these actors configure the user of new contraceptive technologies, particularly contraceptives for men. Although most attention in social studies of technology is focused on innovator’s role in configuring the user, this paper suggests that scientific experts are not the only actors who construct specific representations of the prospective user. In the case of male contraceptives, feminists and journalists have played an active role in articulating and demarcating the potential users of this technology in the making. The paper shows how scientists, feminists, and journalists have constructed a variety of representations of masculinity and male users. These representations function as tools in enhancing the cultural feasibility of a technology or they can be used to denounce the viability of a new technology.
Travail en débat, travailleuses invisibles. Quelques enjeux sexués autour de la redéfinition du «travail»
Authors: Masson Sabine
Published: January 2023

Depuis quelques années, la notion de travail est l’objet d’un intense débat, qui suggère un nouveau point de vue sur les formes et les valeurs du travail. Les différentes hypothèses issues de cette réflexion partagent une même tendance, qui est d’oblitérer le travail des femmes et le rapport des femmes au travail. Un discours normatif sur le travail, qui ne s’énonce pas comme tel, fait ainsi l’impasse sur la problématisation de la différence des sexes et réifîe les catégories de la division sexuelle du travail. Une telle connaissance sur le travail, qui procède par distorsion théorique en gommant les activités des femmes de la définition du «travail», comporte des enjeux sociaux : elle ne peut que renforcer l’exploitation du travail domestique et la dévalorisation des métiers féminins.
Les logiques de recherche d’emploi, entre activités professionnelles et activités domestiques
Authors: Demazière Didier
Published: January 2023

Cet article est consacré à l’analyse de récits de recherche d’emploi collectés auprès d’individus, hommes et femmes, entrés deux ans plus tôt en chômage. La spécificité des récits au féminin est qu’ils nouent engagement dans la recherche d’emploi et gestion des activités domestiques, alors que les récits des hommes sont exclusivement centrés sur les expériences visant à prendre position sur le marché du travail. Cette différence montre que la division sexuelle du travail se prolonge dans le chômage et la recherche d’emploi. Mais les tentatives pour concilier les impératifs de la recherche d’emploi et les contraintes domestiques sont multiples, et l’analyse des entretiens réalisés auprès des femmes permet de dégager cinq manières typiques de négocier avec les difficultés de la quête d’un emploi et avec la force des charges domestiques. Dans tous les cas, il apparaît que l’employabilité des femmes se construit dans une double confrontation : à des jugements portés par des acteurs et institutions participant au fonctionnement du marché du travail, d’une part; à des assignations au travail domestique issues de la structuration de la vie privée, de l’autre.
Mouvements sociaux sexués : reproduction et changements
Authors: Dunezat Xavier
Published: January 2023

Dans le cadre d’une recherche sur le «mouvement social sexué» des chômeurs et des chômeuses de Morlaix et de Rennes, l’auteur présente divers éléments qui concourent à illustrer la reproduction et les changements que peuvent connaître les rapports sociaux. L’analyse en termes de reproduction — mais aussi de transformations — des rapports sociaux de classe éclaire le sens que donnent les acteurs et les actrices à leur participation au mouvement des chômeurs/chômeuses tout comme les divisions qu’a connues ce mouvement. La tendance à la reproduction des rapports sociaux de sexe — à travers l’étude de la division sexuelle du travail et de la violence masculine — est soulignée. À mesure que le mouvement dure, l’ordre social traditionnel, remis en question par certains changements dont ces rapports de sexe ont été provisoirement l’objet, est rapidement restauré.
Travail domestique et rapports de pouvoir entre les sexes
Authors: Ahrne Göran , Roman Christine
Published: January 2023

La conception selon laquelle il incombe à la femme d’assumer la responsabilité des enfants et du foyer, et à l’homme de les faire vivre, marque aujourd’hui le pas. À partir d’une enquête réalisée dans le cadre du Livre blanc sur la répartition du pouvoir et des ressources économiques entre hommes et femmes on examinera la façon dont l’appartenance sexuelle et les rapports de pouvoir influent sur les négociations entre conjoints, compte tenu des différences d’intérêts. Comme le montre cette étude, il est rare qu’en la matière il y ait véritablement égalité entre époux ou concubins, malgré les idées qui prévalent à ce propos chez l’un et l’autre sexe, même lorsque les femmes travaillent à temps complet (le partage est nettement plus équitable dans les jeunes couples sans enfant). L’explication de cette inégalité réside dans le poids des normes sexuées et dans les attentes différenciées liées aux rôles des parents. Il apparaît toutefois que les femmes disposant de ressources élevées en termes d’éducation, de revenus ou de statut professionnel rompent plus souvent avec ces normes et parviennent le mieux à imposer leurs exigences quant à la division du travail au sein du couple.

BEING BYZANTINE IN THE POST-1204 EMPIRE OF CONSTANTINOPLE: CONTINUITY AND CHANGE (POLITICS, GOVERNMENT, CHURCH AND RELIGION)
Authors: Van Tricht Filip
Published: January 2023

The impact of the Latin conquest of Constantinople has often been treated from either the perspective of the Western newcomers who established themselves in various Byzantine territories, or from the perspective of the Byzantines who left the regions that came under Latin control and who managed to establish themselves elsewhere (Nicaea, Epiros, Trebizond). In this contribution the momentous consequences of the Fourth Crusade are addressed from the perspective of those Byzantines that came under Latin rule. By zooming in on a selection of individuals and subgroups a picture is sketched of the varied Byzantine experience within the confines of the (Latin) Empire of Constantinople after 1204. Attention will be given to the various – political, religious, socio-economic and cultural – spheres of society. The focus is on the capital and the region around Constantinople, but other regions come into view as well (Thessaloniki, Adrianople, Philippopolis, Achaia/Morea, Attica, Beotia, Euobia, Crete, etc.). Chronologically this contribution is primarily limited to the period until the loss of Latin Constantinople in 1261.
LSTM Hyperparameters optimization with Hparam parameters for Bitcoin Price Prediction
Authors: KERVANCI I.sibel , AKAY Fatih
Published: January 2023

Machine learning and deep learning algorithms produce very different results with different examples of their hyperparameters. Algorithm parameters require optimization because they aren't specific for all problems. In this paper Long Short-Term Memory (LSTM), eight different hyperparameters (go-backward, epoch, batch size, dropout, activation function, optimizer, learning rate and, number of layers) were used to examine to daily and hourly Bitcoin datasets. The effects of each parameter on the daily dataset on the results were evaluated and explained These parameters were examined with hparam properties of Tensorboard. As a result, it was seen that examining all combinations of parameters with hparam produced the best test Mean Square Error (MSE) values with hourly dataset 0.000043633 and daily dataset 0.00073843. Both datasets produced better results with the tanh activation function. Finally, when the results are interpreted, the daily dataset produces better results with a small learning rate and small dropout values, whereas the hourly dataset produces better results with a large learning rate and large dropout values.
Diversidad de género en el directorio: impacto en el riesgo en las empresas mineras que cotizan en la Bolsa de Valores de Lima
Authors: Tresierra Tanaka Álvaro , Gallo Costa Jorge , Correa Cortés Anaís , Noya Reyes Pamela
Published: January 2023

El presente estudio analiza el efecto de la presencia de la mujer en el directorio sobre el riesgo de la empresa, considerando una muestra de 15 empresas mineras que cotizan en la Bolsa de Valores de Lima (BVL). La estimación se realiza utilizando un modelo dinámico, con el objetivo de corregir una posible endogeneidad. Los resultados obtenidos muestran una evidencia significativa, pero no robusta, de la presencia de la mujer en el directorio sobre el riesgo de la empresa. Lo anterior puede deberse a que la presencia de la mujer en el directorio todavía es escasa y esta no tiene impacto en la toma de decisiones. El efecto de la diversidad en el directorio sobre el riesgo de la empresa ha recibido especial atención durante la última década. Para el caso peruano, no hay antecedentes sobre estudios similares, lo que representa un aporte importante, dada la relevancia de esta actividad económica para el país, así como su posición en la producción de importantes minerales, como el cobre y el oro.
Total spectral power-based method for estimating Brillouin frequency shift in optical fibers

Published: January 2023

A cost-effective method for estimating the Brillouin frequency shift (BFS) of the whole sensing fiber without using an electrical spectrum analyzer is developed. The Brillouin gain spectrum is down-converted and low-pass-filtered, and its total transmitted power is used to estimate the BFS. The strain dynamic range of this method is experimentally shown to be double the value of a conventional slope-assisted method.

Clean-catch midstream urine sample was collected and processed for culture and sensitivity as per standard guidelines.Results: Overall incidence of asymptomatic bacteriuria was 11.9%. The incidence of asymptomatic bacteriuria in pregnant females was 3.1% whereas the incidence in post-natal females was 40%. None of the non-pregnant females had asymptomatic bacteriuria. Conclusion: Screening of antenatal and post-partum females is required to avoid adverse outcomes.
Proactive Edge Caching in Vehicular Networks: An Online Bandit Learning Approach
Authors: Wang Qiao , Grace David
Published: January 2023

Proactively caching content at the network edge is particularly effective in high-mobility vehicular networks, where intermittent connection is the major challenge for seamless content transmission. The objective of this paper is to achieve proactive caching in vehicular networks by mobility prediction, specifically by predicting the next roadside unit (RSU) for a vehicle with reinforcement learning techniques. The paper proposes two proactive caching algorithms based on multi-armed bandit (MAB) learning, non-contextual MAB and contextual MAB, respectively. This paper fills the void in the literature regarding the application of MAB learning to mobility-prediction based proactive caching. Their feasibility, superiority, and applicability are evaluated with simulation in two modern cities: Las Vegas, USA with a grid road layout, and Manchester, UK with a more historical layout. Additionally, this paper is the first that proposes to investigate the uncertainty associated with proactive caching systems in the form of entropy with a specifically extended Subjective Logic framework, in order to provide an insight into the underlying link between prediction accuracy and uncertainty. 
Filter method-based feature selection process for unattributed-identity multi-target regression problem
Authors: Garcia Iker , Santana Roberto
Published: January 2023

In this paper, for the first time, a feature selection (FS) problem for an unattributed-identity multi-target regression (UIMTR) problem is presented. UIMTR is defi?ned as a multi-target regression problem where the set of target and predictor variables are undetermined, i.e., the identity of the variables is unattributed. Two forward selection ?filter-based mutual information sequential-methods are proposed. In particular, the proposed methods are multi-objective adaptations of the classical Mutual Information Maximization (MIM) and Maximum Relevance Minimum Redundancy (mRMR). The concept of "sentinel variable" is also introduced in this paper: any variable selected by the methods that, a posteriori, will be a predictor variable (its real-time data will be used by the models to predict the value of the target variables). To highlight the existence of this type of problems in the industry, and thus the need for this approach, a current problem of low voltage power grids is presented and modelled. In particular, the question of selecting a subset of smart meters ("sentinel smart meters") that serve as predictors of a certain electrical measurement for the rest of the smart meters in the grid. The empirical approach will be applied to voltage curves of smart meters for six different transformer substations. The results are evaluated from three perspectives: (i) the quality of the predictions, (ii) the stability of the methods and (iii) the execution time. In addition, the results are compared with three other methods, a purely empirical one proposed in the article (based on voltage patterns (VP)) and another two which are well-known in the literature: (a) RReliefF (Relief for regressions) and (b) Fisher Score.
LPV modeling and PI-based H∞ Control for a Tailless Flapping Wing Micro Aerial Vehicle With Parameter Uncertainties and Input Saturation
Authors: Guo Qingcheng , Zhang Weiping , Deng Zhicheng , Mou Jiawang , Wu Chaofeng
Published: January 2023

To overcome the aerodynamic and system parameters uncertainties of the tailless flapping wing micro aerial vehicle (FWMAV) caused by inaccurate measurement, we establish an linear parameter varying (LPV) model and propose a H∞ controller with the proportional-integral (PI) structure for a FWMAV. First, the FWMAV system with parameter uncertainties is modeled as a polytopic LPV system. To enable computationally practical implementation on microcontroller, we restrict our controller to have a designed multivariable PI structure, using sampling measurements. Then, using an input delay technique, the sampled-data system is converted into a continuous time systems with a state delay. A Lyapunov functional approach is employed to establish the stability and H∞ performance of the closed-loop. Additionally, we add more bilinear matrix inequalities (BMIs) constraints to avoid input saturation, which relieve the small torque actuator problem in FWMAV control. The BMI problem is converted into a convex optimization problem involving linear matrix inequalities (LMIs) using block matrices hypotheses. Numerical simulations show that the proposed controller possesses superior performance and stronger robustness compared with another state-of-the-art controller. The flight experiments verify the effectiveness and practicability of the proposed controller.
On the hit problem for the polynomial algebra and the algebraic transfer
Authors: Võ Phúc Đặng
Published: January 2023

Let $\mathcal A$ be the classical, singly-graded Steenrod algebra over the prime order field $\mathbb F_2$ and let $P^{\otimes h}: = \mathbb F_2[t_1, \ldots, t_h]$ denote the polynomial algebra on $h$ generators, each of degree $1.$ Write $GL_h$ for the usual general linear group of rank $h$ over $\mathbb F_2.$ Then, $P^{\otimes h}$ is an $\mathcal A[GL_h]$-module. As well known,  the (mod 2) cohomology groups of the Steenrod algebra, ${\rm Ext}_{\mathcal A}^{h, h+*}(\mathbb F_2, \mathbb F_2)$ is still largely mysterious for all homological degrees $h \geq 6.$ The $h$-th algebraic transfer $Tr_h^{\mathcal A}: (\mathbb F_2\otimes_{GL_h}{\rm Ann}_{\overline{\mathcal A}}[P^{\otimes h}]^{*})_n\longrightarrow {\rm Ext}_{\mathcal A}^{h, h+n}(\mathbb F_2, \mathbb F_2),$ defined by Singer [Math. Z. \textbf{202} (1989), 493-523], is a helpful tool to describe that Ext groups. Singer conjectured that this homomorphism is a monomorphism for any $h>0.$ There is currently no information about the conjecture for $h = 6.$ The purpose of this Note is to study Singer's conjecture for all $h\geq 1$ in degrees $n\leq 10 = 6(2^{0}-1) + 10\cdot 2^{0}$ and for $h=6$ in general degree $n:=n_s=6(2^{s}-1) + 10\cdot 2^{s},\, s\geq 0.$ Our approach is based on techniques of the hit problem for $P^{\otimes h}.$ This also extends a result in Mothebe et al. [J. Math. Res. \textbf{8} (2016), 92-100] on the hit problem for $P^{\otimes 6}$ in degree $n_s.$ More generally, for $h\geq 6,$ we show that the dimension of the cohit module $\mathbb F_2\otimes_{\mathcal A}P^{\otimes h}$ in degrees $2^{s+4}-h$ is equal to the order of the factor group of $GL_{h-1}$ by the Borel subgroup $B_{h-1}$ for every $s\geq h-5.$ Especially, for the Galois field $\mathbb F_{q}$ ($q$ denoting the power of a prime number), based on Hai's recent work [C. R. Math. Acad. Sci. Paris \textbf{360} (2022), 1009-1026], we claim that the dimension of the space of the indecomposable elements of $\mathbb F_q[t_1, \ldots t_h]$ in degrees $q^{h-1}-h$ is equal to the order of the factor group of $GL_{h-1}(\mathbb F_q)$ by a subgroup of the Borel group $B_{h-1}(\mathbb F_q).$ As applications, we establish the dimension result for the cohit module $\mathbb F_2\otimes_{\mathcal A}P^{\otimes 7}$ in degrees $n_{s+5},\, s > 0.$ At the same time, we prove that the non-zero elements $h_2^{2}g_1 = h_4Ph_2\in {\rm Ext}_{\mathcal A}^{6, 6+n_1}(\mathbb F_2, \mathbb F_2)$, and $D_2\in {\rm Ext}_{\mathcal A}^{6, 6+n_2}(\mathbb F_2, \mathbb F_2)$ are not in the image of $Tr_6^{\mathcal A}.$ We also give some conjectures on the $h$-th cohomology groups of the algebra $\mathcal A$ for $h\geq 6,$ and discuss their relationship to previous works.

Deep learning methods using multimodal imagings have been proposed for the diagnosis of Alzheimer's disease (AD) and its early stages (SMC, subjective memory complaints), which may help to slow the progression of the disease through early intervention. However, current fusion methods for multimodal imagings are generally coarse and may lead to suboptimal results through the use of shared extractors or simple downscaling stitching. Another issue with diagnosing brain diseases is that they often affect multiple areas of the brain, making it important to consider potential connections throughout the brain. However, traditional convolutional neural networks (CNNs) may struggle with this issue due to their limited local receptive fields. To address this, many researchers have turned to transformer networks, which can provide global information about the brain but can be computationally intensive and perform poorly on small datasets. In this work, we propose a novel lightweight network called MENet that adaptively recalibrates the multiscale long-range receptive field to localize discriminative brain regions in a computationally efficient manner. Based on this, the network extracts the intensity and location responses between sMRI and FDG-PET as an enhancement fusion for AD and SMC diagnosis. Our method is evaluated on the publicly available ADNI datasets and achieves 97.67% accuracy in AD diagnosis tasks and 81.63% accuracy in SMC diagnosis tasks using sMRI and FDG-PET. These results achieve state-of-the-art (SOTA) performance in both tasks. To the best of our knowledge, this is one of the first deep learning research method for SMC diagnosis with FDG-PET.
Rhodes: A Next-Generation OS based on Resource Governance Model
Authors: Wang Changsheng
Published: January 2023

The kernel is the core part of an operating system. At present, four types of kernels are widely available: monolithic kernels, microkernels, hybrid kernels, and exokernels. These kernel architectures are either too tightly-coupled, like monolithic kernels, put too many modules into the kernel, or too free, like exokernels, allow users to freely develop core features such as IPC, Virtual Memory, etc, or have no rules, like hybrid kernels, kernel modules organization is uncontrolled. In recent years, to solve these problems, resource management concept frequently appears in industry and academia. Although resource management concept makes resources in OSes orderly, no existing OSes or software systems can modify and extend management rules conveniently and dynamically.

This paper proposes a resource governance model that places resources such as applications and hardware into the model. Through unified rule governance, the organization of resources is more orderly and scalable. At the same time, by separating rules from resources, rules in the model are also scalable and flexible. Based on the model, we built Rhodes OS that allows users to modify and extend resource management rules by governance center which separates rules from resources. In addition, Rhodes also fits all kinds of OSes that are optimized for specific scenarios such as mobile, big data, IoT and AI. We implemented Rhodes on x86-64 and evaluated it. Our evaluation results show that applications performance in Rhodes is equivalent to Linux in native mode. So we believe that OSes will enter resource governance age from resource management age in the near future.
Finite Set Sensorless Control With Minimum a Priori Knowledge and Tuning Effort for Interior Permanent Magnet Synchronous Motors
Authors: Brosch Anian , Tinazzi Fabio , Wallscheid Oliver , Zigliotto Mauro , Böcker Joachim
Published: January 2023

By applying rotor angle sensorless control methods the costs of the electrical drive can be decreased while its reliability is increased. Traditionally, the design of both the rotor angle estimator and the drive controller require a detailed motor model and manual tuning leading to significant effort by human experts. In this work, a rotor anisotropy-based sensorless control scheme for interior permanent magnet synchronous motors (IPMSM) is proposed that enables sensorless control with minimum tuning effort and a priori motor knowledge. Due to these characteristics the scheme is particularly suitable for self-commissioning or low-cost drive applications. The scheme contains a finite control set model predictive current controller (FCS-MPCC) with an additional inequality constraint that enables the identification of the motor model in the stator-fixed coordinate system by using the last three measurement samples. Utilizing an automatic system identification procedure, the motor model is determined online in a data-driven fashion. The identified motor model serves both as prediction model of the FCS-MPCC and as  baseline for the rotor angle estimation via an eigenvalue decomposition approach. Challenging experimental investigations at standstill up to the medium speed range prove the applicability of the proposed approach. Here,  highly dynamic speed and current transients can be handled by the proposed method.
A Submillimeter-Wave FMCW Pulse-Doppler Radar to Characterize the Dynamics of Particle Clouds
Authors: Bryllert Tomas , Bonmann Marlene , Stake Jan
Published: January 2023

This work presents a 340-GHz frequency-modulated continuous-wave (FMCW) pulse-Doppler radar. The radar system is based on a transceiver module with about one milli-Watt output power and more than 30-GHz bandwidth. The front-end optics consists of an off-axis parabola fed by a horn antenna from the transceiver unit, resulting in a collimated radar beam. The digital radar waveform generation allows for coherent and arbitrary FMCW pulse waveforms. The performance in terms of sensitivity and resolution (range/cross-range/velocity) is demonstrated, and the system's ability to detect and map single particles (0.1–10 mm diameter), as well as clouds of particles, at a 5-m distance, is presented. A range resolution of 1 cm and a cross-range resolution of a few centimeters (3-dB beam-width) allow for the characterization of the dynamics of particle clouds with a measurement voxel size of a few cubic centimeters. The monitoring of particle dynamics is of interest in several industrial applications, such as in the manufacturing of pharmaceuticals and the control/analysis of fluidized bed combustion reactors.
On the equation used to calculate lens surface radius of curvature based on the number of Newton’s ring
Authors: Sun Haiyin
Published: January 2023

Newton’s ring is the most used method to test surface radius of curvature of a lens. An approximate equation is currently widely used by lens fabrication shops and in literatures to calculate the error of surface radius of curvature based on the number of exhibited Newton’s ring. It is shown in this paper that this approximate equation contains significant error and should be replaced by two other simple equations derived in a recently published paper.

YoloCurvSeg: You Only Label One Noisy Skeleton for Vessel-style Curvilinear Structure Segmentation

Published: January 2023

Weakly-supervised learning (WSL) has been proposed to alleviate the conflict between data annotation cost and model performance through employing sparsely-grained (i.e., point-, box-, scribble-wise) supervision and has shown promising performance, particularly in the image segmentation field. However, it is still a very challenging problem due to the limited supervision, especially when only a small number of labeled samples are available. Additionally, almost all existing WSL segmentation methods are designed for star-convex structures which are very different from curvilinear structures such as vessels and nerves. In this paper, we propose a novel sparsely annotated segmentation framework for curvilinear structures, named YoloCurvSeg, based on image synthesis. A background generator delivers image backgrounds that closely match real distributions through inpainting dilated skeletons. The extracted backgrounds are then combined with randomly emulated curves generated by a Space Colonization Algorithm-based foreground generator and through a multilayer patch-wise contrastive learning synthesizer. In this way, a synthetic dataset with both images and curve segmentation labels is obtained, at the cost of only one or a few noisy skeleton annotations.

Finally, a segmenter is trained with the generated dataset and possibly an unlabeled dataset. The proposed YoloCurvSeg is evaluated on four publicly available datasets (OCTA500, CORN, DRIVE and CHASEDB1) and the results show that YoloCurvSeg outperforms state-of-the-art WSL segmentation methods by large margins. With only one noisy skeleton annotation (respectively 0.14%, 0.03%, 1.40%, and 0.65% of the full annotation), YoloCurvSeg achieves more than 97% of the fully-supervised performance on each dataset. Code and datasets will be released at https://github.com/llmir/YoloCurvSeg.
CBDC bridging between Hyperledger Fabric and permissioned EVM-based blockchains

Published: January 2023

The last few years have seen a steep increase in blockchain interoperability research. Most solutions connect public blockchains; hence, the main cross-chain use case is token transfer. By-design platform transparency, tamper-resistance, and auditability make blockchains an infrastructure candidate for Central Bank Digital Currencies (CBDCs), but bridging CBDCs is an important missing piece in general. In this paper, we leverage an asset transfer protocol, ODAP/SATP, to define an extendable and dependable blockchain interoperability middleware that can bridge CBDC from Hyperledger Fabric to EVM-based permissioned blockchains. The key interoperation enabler in the solution is a shared asset definition enforced by both sides of the bridge, accompanied by a mapping between Fabric Identities and Ethereum addresses for Identity management. We implement our design for the CBDC use case utilizing Hyperledger Cactus. Through a preliminary performance evaluation, we show that the underlying ledgers heavily influence the latency of the solution, not the bridging components.
