Skilled motor performance depends critically on rapid corrective responses that act to preserve the goal of the movement in the face of perturbations. Although it is well established that the gain of corrective responses elicited while reaching toward objects adapts to different contexts, little is known about the adaptability of corrective responses supporting the manipulation of objects after they are grasped. Here, we investigated the adaptability of the corrective response elicited when an object being lifted is heavier than expected and fails to lift off when predicted. This response involves a monotonic increase in vertical load force triggered, within ∼90 ms, by the absence of expected sensory feedback signaling lift off and terminated when actual lift off occurs. Critically, because the actual weight of the object cannot be directly sensed at the moment the object fails to lift off, any adaptation of the corrective response would have to be based on memory from previous lifts. We show that when humans, including men and women, repeatedly lift an object that on occasional catch trials increases from a baseline weight to a fixed heavier weight, they scale the gain of the response (i.e., the rate of force increase) to the heavier weight within two to three catch trials. We also show that the gain of the response scales, on the first catch trial, with the baseline weight of the object. Thus, the gain of the lifting response can be adapted by both short- and long-term experience. Finally, we demonstrate that this adaptation preserves the efficacy of the response across contexts.SIGNIFICANCE STATEMENTHere, we present the first investigation of the adaptability of the corrective lifting response elicited when an object is heavier than expected and fails to lift off when predicted. A striking feature of the response, which is driven by a sensory prediction error arising from the absence of expected sensory feedback, is that the magnitude of the error is unknown. That is, the motor system only receives a categorical error indicating that the object is heavier than expected but not its actual weight. Although the error magnitude is not known at the moment the response is elicited, we show that the response can be scaled to predictions of error magnitude based on both recent and long-term memories.

Published: October 2023

Nowadays, social networks play a central role in communication media. In this scenario, analysing the gender awareness fostered by the influencers is crucial.
The research explores the female representation portrayed by eight Spanish influencers who address the gender approach from graphic communication. All of them are women illustrators, cover topics related to gender, and use similar communication strategies.
The methodology includes three complementary techniques: first, desktop study to compare the illustrators’ profiles; second, content analysis to delve into the topics addressed and their artivism; third, a Delphi method to assess their contribution to promoting gender egalitarian values, in which experts specialising in communication, philosophy, sociology, psychology, and politics participate.
The results show that feminism is a prominent topic in their publications, stimulating a feeling of sisterhood among women, their core target. From a generational perspective, the influence of their message is more significant on millennials and centennials. Conclusions confirm that social media characteristics, artivism, content hybridisation and transmediality enhance their feministic discourse. Future lines of research may focus on identifying other channels and communication strategies more influential for broad target groups, especially men and generations older than millennials, since these external audiences seem crucial to spread gender awareness.

Ouémé catchment experiences increasing degradation of its natural resources due to anthropogenic pressure. Consequently, most of the agroforestry species as well as the cultural and Indigenous knowledge related to them are facing a very high risk of extinction. The present research aimed to assess the biodiversity of the useful woody species in this area and their cultural importance and then prioritize these woody species for conservation purpose. An ethnobotanical survey was carried out among 411 randomly selected households followed by an ecological survey conducted in 69 random plots of 0.15 ha. Ecological and ethnobotanical parameters were calculated and then analyzed. To determine the local priorities species for conservation, a local conservation priority index (LCPI) was computed for each species. The high value of LCPI for a given species indicates the need for a greater level of attention for conservation and management. Forty-five useful woody species belonging to 21 families dominated by Leguminosae (24.44%) and Anacardiaceae (8.88%) were reported. The forty-five species were categorized in six use categories by the informants: food, medicinal, construction, fuel, veterinary and technology. The most useful species were Elaeis guineensis (UV=0.24), followed by Parkia biglobosa (UV=0.19) and Vitellaria paradoxa (UV=0.18). The prioritization method yielded top ten ranked species: Adansonia digitata, Parkia biglobosa, Pterocarpus erinaceus, Irvingia gabonensis, Milicia excelsa, Tamarindus indica, Vitex doniana, Prosopis africana, Diospyros mespiliformis and Pterocarpus santalinoides. With the aim of establishing the sustainable management in the catchment, we suggest that more attention be paid to the aforementioned species as part of rehabilitation activities.

Reduzir o impacto ambiental e cumprir com o compromisso social, respeitando o meio ambiente para promover a sustentabilidade em processos produtivos tem sido debatido em diversos setores e, nos processos construtivos, a tecnologia é um aliado, pois a automatização e a inserção de componentes aos materiais, há uma diminuição de resíduos e melhora da qualidade das edificações. Diante disso, este estudo teve por objetivo avaliar a construtibilidade e a extrudabilidade na construção civil por meio da inserção de grafite e óxido de grafeno em matriz cimentícia. Os filamentos cimentícios produzidos foram avaliados quanto aos parâmetros físicos, químicos e mecânicos. Os resultados obtidos apontaram que a inserção tanto de grafite quanto de óxido de grafite na matriz cimentícia não interferiu na extrudabilidade e na construtibilidade do material. . Foram obtidos valores de 9,34 MPa, 8,99 MPa e 8,91 MPa para a tração na flexão nas amostras acrescidas de 0,04% e 0,1% de grafite e 0,04% de óxido de grafeno, respectivamente. Quando avaliados quanto à compressão axial, as amostras que continham óxido de grafeno com 0,1% e 0,2% e amostra de referência tiveram os valores de 127.546,00 MPa, 127.350,05 MPa, 126.844,12 MPa, respectivamente. A amostra com 0,1% de grafite apresentou comportamento positivo com relação ao teste de tração à flexão, compressão e menor deformação após a impressão, tornando viável a adição dos nanomateriais em filamento cimentício para manufatura aditiva, de forma a possibilitar a produção de materiais mais resistentes.

Introduction Proximal femur fractures can be associated with nailing and total hip arthroplasty (THA). Treatment of elderly inpatients necessitates adequate postoperative pain relief. Obese patients require specific inpatient and outpatient treatments.The objective was to evaluate the effectiveness of pain relief in obese patients at the stages of rehabilitation after primary THA performed for a proximal femur fracture.Material and methods VAS score was compared in two groups of 60 clinical cases to evaluate the effectiveness of postoperative multimodal pain relief using the author's method.Results Comparable results of an effective and stable pain relief were obtained in the two groups by the time the patient was discharged from the hospital 5-6 days after THA. Multimodal analgesia with a glucocorticosteroid injected in the projection of the sacroiliac joint provided an effect being greater by 29 % than with use of opioids after two postoperative days and by 11 % after five postoperative days.Discussion Old age, comorbidities are associated with optimal surgical strategy. THA in patients with extra-articular proximal femur fractures can improve the rehabilitation potential early after surgery and general clinical and functional results providing high quality of life in the late rehabilitation period.Conclusion THA demonstrated a stable positive effect of pain relief in the study group of patients with proximal femur fractures, regardless of the weight and the height. Positive dynamics in pain relief was seen in patients with elevated BMI of any gradation, including those with BMI ≥ 40.

Background: Meconium aspiration syndrome (MAS) is as a result of aspiration of meconium-stained amniotic fluid antepartum or postpartum in term or near-term infants resulting in respiratory morbidity of varying severity. The present study was conducted to assess the clinical outcome of babies born through meconium stained liquor.
Methods: This is a prospective observational study of babies born through meconium stained liquor at ESIC Medical College and Post Graduate Institute of Medical Science and Research over a period of 18 months from March 2021 to August 2022.
Results: Majority of the babies were born through thin MSL. The highest incidence of MSL is seen in term babies. Normal vaginal delivery was the predominant mode of delivery. Thick MSL babies had low APGAR score at 1min .Majority of the thick MSL group had moderate to severe respiratory distress. Thick MSL babies required invasive mechanical ventilation compared to thin MSL group. Thick MSL study group had moderate to severe meconium aspiration syndrome compared to thin MSL study group. Perinatal depression was the most commonly associated complication in this study. Sepsis and PPHN were the complications that lead to mortality among the study group. Higher morbidity was seen in thick MSL group. The overall mortality was 1.6% and morbidity 55.2%.
Conclusions: Thick meconium stained amniotic fluid is associated with increased risk perinatal depression, persistent pulmonary hypertension, sepsis, severe meconium aspiration syndrome and mortality.

Mixed extragonadal teratoma with malignant nephroblastoma (TWN) is an exceptionally rare and complex combination of solid tumors which has been referred to as “teratoid Wilms tumor,” “teratoid nephroblastoma,” or “teratoma with nephroblastoma.” Here we report a seven-year-old male who presented with a large retroperitoneal mass outside of the right kidney with lung metastases and diagnosed with a malignant mixed germ cell tumor with mature teratoma and extensive malignant nephroblastoma. Our case report highlights the controversial pathogenesis of this rare tumor and describes the variety of treatment regimens delivered for this type of tumor. In this case report, we described a young child with metastatic TWN who was successfully treated with multimodal approach based on Wilms tumor management including surgery, chemotherapy, and radiation.

The main goal of the reviewed article is to provide statistically determined relationships between the parameters of disintegration processes and the properties of rocks. The results of theoretical and experimental studies are discussed and analysed in the article. In relation to drilling, the formulas of drilling speed, depending on various parameters as an indicator that fully reflects the efficiency of the process, are given and compared. Thus, the drilling speed for percussion drilling is related to the characteristics of the rock and, at the same time, taking into account the constructional characteristics of the drilling tool. In percussion drilling, a new formula for drilling speed is presented, considering each impact and the frequency of the impact. The expression for the drilling speed was determined taking into account the degree of crushing of the rock matrix during drilling. Thus, the drilling speed is determined by considering the contact strength of the rock being drilled in the mechanical drilling method. The distribution of the stress state in the drilling zone was determined. Also, the shape and development characteristics of the cracks formed in the rock during the operation of the drilling tool (especially the dynamic percussions of the tool in the bottom zone of the well) were investigated. It should be noted that the energy intensity of the drilling process in the rock was determined by studying the next stages of the process of breaking the rock. The technical and economic indicators of the drilling works have been evaluated. Corresponding mathematical formulas are presented as a reliable calculation of drilling rates. The relevant mechanical and geophysical properties of the excavated rocks were considered. In the article, the drilling tools are selected depending on the drilling method, physical-mechanical properties of the rocks and geological conditions of the rock mass. The results of the obtained studies can be used in the design of the technological parameters of the drilling. The observations and results expressed in the article have a theoretical and practical aspect.

Abstract

Protein catalysis and allostery require the atomic-level orchestration and motion of residues, ligand, solvent and protein effector molecules, but the ability to design protein activity through precise protein-solvent cooperative interactions has not been demonstrated. Here, we report the design of a dozen novel membrane receptors catalyzing G-protein nucleotide exchange through diverse de novo engineered allosteric pathways mediated by cooperative networks of intra-protein, protein-ligand and solvent molecule interactions. Consistent with the predictions, designed protein activities correlated well with the level of plasticity of the network at flexible transmembrane helical interfaces. Several designs displayed considerably enhanced thermostability and activity compared to related natural receptors. The most stable and active variant crystallized in an unforeseen signaling active conformation, in excellent agreement with the design models. The allosteric network topologies of the best designs bear limited similarity to those of natural receptors and reveal a space of allosteric interactions larger than previously inferred from natural proteins. The approach should prove useful for engineering proteins with novel complex protein binding, catalytic and signaling activities.
Problem of integrating Blockchain Technologies into Wireless Mesh Networks: Application to Community Wireless Networks
Authors: NDIÉ Thomas DJOTIO , DOBE Abel 
Published: October 2023

Abstract
Wireless mesh networks (WMNs), because of their low installation costs compared to the network infrastructure, were seen as a relevant alternative to connect remote areas and poor regions where telephone companies have great apprehension to invest. However, WMNs have security vulnerabilities, including denial of service (DoS) and identity theft attacks. The most common methods for securing mesh networks are centralized systems, while WMNs are decentralized, open and flexible by design. The usual blockchain integration in WMNs is more oriented towards the construction of online payment platforms. This paper proposes BlockWMN, a model for integrating blockchain technology into WMNs with the ultimate goal of protecting them from the abovementioned attacks. Fundamentally, we address a consensus issue or a so-called "Byzantine Generals" or "Byzantine Fault Tolerance" (BFT) problem. Our approach uses the blockchain as a secure database to save the network graph and all the network nodes’ credentials in real time. Each node has the ability to check in the blockchain all signaling information received from other nodes. Unlike other approaches, our solution is decentralized, open and flexible. The limits of our model are inherent to the nature of blockchains: high energy consumption for the calculation of the proof of work and memory space for the storage of blockchain information.

Published: October 2023

Abstract

A practical limit to energy efficiency in computation is ultimately from noise, with quantum noise [1] as the fundamental floor. Analog physical neural networks [2], which hold promise for improved energy efficiency and speed compared to digital electronic neural networks, are nevertheless typically operated in a relatively high-power regime so that the signal-to-noise ratio (SNR) is large (>10). We study optical neural networks [3] operated in the limit where all layers except the last use only a single photon to cause a neuron activation. In this regime, activations are dominated by quantum noise from the fundamentally probabilistic nature of single-photon detection. We show that it is possible to perform accurate machine-learning inference in spite of the extremely high noise (signal-to-noise ratio ~1). We experimentally demonstrated MNIST handwritten-digit classification with a test accuracy of 98% using an optical neural network with a hidden layer operating in the single-photon regime; the optical energy used to perform the classification corresponds to 0.008 photons per multiply-accumulate (MAC) operation, which is equivalent to 0.003 attojoules of optical energy per MAC. Our experiment also used >40× fewer photons per inference than previous state-of-the-art low-optical-energy demonstrations [4, 5] to achieve the same accuracy of >90%. Our training approach, which directly models the system’s stochastic behavior, might also prove useful with non-optical ultra-low-power hardware.
Exploiting Hidden Information Leakages in Backward Privacyfor Dynamic Searchable Symmetric Encryption

Published: October 2023

Abstract
Dynamic searchable symmetric encryption (DSSE) enables searches over encrypted data as well as data dynamics such as flexible data addition and deletion operations.A major security concern in DSSE is how to preserve forward and backward privacy, which are typically achieved by removing the linkability between the newly added data and previous queries, and between the deleted data and future queries, respectively. After information leakage types were formally defined for different levels of backward privacy (i.e., Type-I, II, III), many backward-private DSSE schemes have been constructed under the definitions. However, we observed that the backward privacy can be violated by leveraging additional secondary leakage which is typically leaked in specific constructions of schemes in spite of their theoretical guarantees.In this paper, in order to understand the security gap between the theoretical definitions and practical constructions, we conduct an in-depth analysis of the root cause for the secondary leakage, and demonstrate how it can be abused to violate Type-II backward privacy (e.g., the exposure of the deletion history) of DSSE constructions in practice.
We then propose a novel Type-II backward private DSSE scheme based on Intel SGX which is resilient to the secondary leakage abuse attack. According to the comparative analysis of our scheme with the state-of-the-art SGX-based DSSE schemes, Bunker-B (EuroSec'19) and SGX-SE1 (ACNS'20),our scheme shows higher efficiency in terms of the search latency with a negligible utility loss under the same security level (cf. Bunker-B); while showing similar efficiency with a higher security level (cf. SGX-SE1). Finally, we formally prove that our scheme guarantees Type-II backward privacy.
