The Emergence of the Replica Model? An Analysis of the Question of the ‘Copies of Rome’ in Late Republican Colonization Through Three Case-Studies

The debate around the replica model of Roman colonization has traditionally been focused on the early to mid-Republican colonial foundations in Italy. In this context, scholars have, in the last decades, rightly challenged the former orthodoxy to assert that these colonies were not, as was previously assumed, replicas of Rome. These same scholars, however, have often stated that these replicas were the result of later Republican and imperial colonial practices that emerged in this period. This paper puts this assumption of the ‘emergence of the replica model’ to the test to show that this is not the case. Through an examination of the elements of the replica model, as well as a series of three case-studies (Corinth, Urso, and Pompeii), the present work will show that there is no evidence to suggest a replica model in the colonies of the Late Republic and Early Empire, but rather, at most, an inspiration taken from Roman institutions that can hardly be identified with the traditional arguments of the simulacrum.

How perceived coolness and wow affect customer engagement: the role of self-image congruity

PurposeCustomer engagement has key practical implications for hospitality management. However, little is known about how perceived coolness and wow affect customer engagement. The purpose of this research was to investigate the associations among perceived coolness, perceived wow and customer engagement and examine the mediator of self-image congruity (SIC).Design/methodology/approachSurvey data were collected from 406 restaurant customers in Taiwan, and structural equation modeling was adopted to examine the hypotheses. Furthermore, a replica model was produced for another sample of 412 hotel customers.FindingsThe results indicate that perceived coolness positively affects customer engagement and SIC and that perceived wow positively affects SIC. SIC positively affects customer engagement. Moreover, SIC mediates the associations of perceived coolness and wow with customer engagement. The relationships between the variables did not significantly differ between restaurant customers and hotel customers.Practical implicationsHospitality businesses can create environments in which customers interact with service providers through innovative technology, thereby encouraging engagement. Coolness and the wow factor must be prioritized in servicescapes, meal and room design, the service process and creative marketing.Originality/valueThe findings contribute knowledge on hospitality, factors affecting customer engagement and the mediating mechanism of SIC. Hospitality managers can use the results to formulate strategies for servicescape design, brand management and customer experience.

OPTIMALIZATION OF BREASTFEEDING TECHNIQUES USING “BREAST MODELS”

Exclusive breastfeeding is an attempt at enhancing the health and survival of infants during the initial 6 months of life. The World Health Organization (WHO) states that 2 out of 3 infants worldwide do not receive exclusive breastfeeding for the full 6 months. According to UNICEF, it is projected that by 2022, less than half (48%) of infants globally will be exclusively breastfed. The advantages of exclusive breastfeeding for infants encompass the acquisition of antibodies to prevent exposure to diseases, facilitation of brain and physical development, and mitigation of the risk of stunting. The successful practice of exclusive breastfeeding is profoundly affected by both intrinsic and extrinsic factors. Among the intrinsic factors that impact breastfeeding behavior, knowledge stands out. Insufficient or inaccurate information regarding the benefits of breastfeeding, the mechanism of milk production, as well as attachment and breastfeeding positions, are subjects that contribute to challenges in the breastfeeding process. Elevating awareness and comprehension of breast anatomy, milk production mechanisms, and proper attachment during breastfeeding among postpartum mothers will heighten self-efficacy concerning belief in behavioral change. Community service initiatives employ the health education approach utilizing a replica model of breast anatomy. The counseling sessions target parents (both husband and wife) undergoing postnatal health monitoring, and who are recipients of care in the postnatal care unit. The outcomes of this undertaking reveal a noteworthy 35% enhancement in participants' knowledge subsequent to receiving information on breast anatomy, milk production, and proper attachment."

Nonlinear Model Predictive Control using Neural ODE Replicas of Dynamic Simulators

We propose simulation-based nonlinear model predictive control as a first step towards autonomous decision-making for stable operation of large complex dynamical systems such as chemical plants. The effect of abrupt external disturbances should be quickly eliminated, taking into account such complex dynamic responses, to maintain stable production. In this paper, we propose a control system to eliminate these effects. The system uses engineering models, including dynamic simulators, based on chemical engineering knowledge. Dynamic simulators are generally not differentiable with respect to actions; however, differentiable models are advantageous for fast nonlinear optimization. To take advantage of both reliable dynamic simulators and differentiable models, we introduce neural ordinary differentiable equation models and clone the behaviour of simulators on them. The cloned differentiable neural replica model is then incorporated into a gradient-based nonlinear model predictive control. Evaluation of this method in a real methanol distillation plant confirms that it can significantly remove abrupt heavy rain disturbances compared to existing methods.

Ecological Considerations When Designing Mitigation Translocations: An Australian Reptile Case Study.

Translocation science has made considerable progress over the last two decades; however, reptile translocations still frequently fail around the world. Major knowledge gaps surround the basic ecology of reptile species, including basic factors such as habitat preference, which have a critical influence on translocation success. The western spiny-tailed skink (Egernia stokesii badia) is used here as a case study to exemplify how empirical research can directly inform on-ground management and future translocation planning. A combination of studies, including LiDAR scanning of microhabitat structures, camera trapping, plasticine replica model experiments and unbounded point count surveys to assess predation risk, and visual and DNA analysis of dietary requirements, were all used to better understand the ecological requirements of E. s. badia. We found that the skinks have specific log pile requirements, both native and non-native predator management requirements, and a largely herbivorous, broad diet, which all influence translocation site selection and management planning. The use of E. s. badia as an Australian case study provides a clear strategic framework for the targeted research of meaningful ecological factors that influence translocation decision-making. Similar approaches applied to other reptile species are likely to fundamentally increase the capacity for effective management, and the likelihood of future successful translocations.

Interference Screw versus Cement Fixation in Anterior Cruciate Ligament Soft Tissue Grafts: A Biomechanical Study.

Shortcomings of fixation have been reported as a source of graft failure in anterior cruciate ligament (ACL) reconstruction. While interference screws have long been used as fixation devices for ACL reconstruction, they are not without complications. Previous studies have highlighted the use of bone void filler as a fixation method; however, no biomechanical comparisons using soft tissue grafts with interference screws exist to our knowledge. The purpose of this study is to evaluate the fixation strength of a calcium phosphate cement bone void filler compared with screw fixation in an ACL reconstruction bone replica model with human soft tissue grafts. In total, 10 ACL grafts were constructed using semitendinosus and gracilis tendons harvested from 10 donors. Grafts were affixed with either an 8-10 mm × 23 mm polyether ether ketone interference screw (n = 5) or with approximately 8 mL of calcium phosphate cement (n = 5) into open cell polyurethane blocks. Graft constructs were tested to failure in cyclic loading under displacement control at a rate of 1 mm per second. When compared with screw construct, the cement construct showed a 978% higher load at yield, 228% higher load at failure, 181% higher displacement at yield, 233% higher work at failure, and a 545% higher stiffness. Normalized data for the screw constructs relative to the cement constructs from the same donor showed 14 ± 11% load at yield, 54 ± 38% load at failure, and 172 ± 14% graft elongation. The results of this study indicate that cement fixation of ACL grafts may result in a stronger construct compared with the current standard of fixation with interference screws. This method could potentially reduce the incidence of complications associated with interface screw placement such as bone tunnel widening, screw migration, and screw breakage.

Accelerated settling velocity of airborne particulate matter on hairy plant leaves

Phytoremediation has emerged as an ecofriendly technique to reduce hazardous particulate matter (PM) in the air. Although previous studies have conducted statistical analyses to reveal PM removal capabilities of various plant species according to their leaf characteristics, the underlying physical mechanism of PM adsorption of plants remains unclear. Conventional methodologies for measuring PM accumulation usually require long-term field tests and provide limited understanding on PM removal effects of individual leaf traits of various plants. In this study, we propose a novel methodology which can compare the electrostatic interactions between PMs and plant leaves according to their trichome structures by using digital in-line holographic microscopy (DIHM). Surface characteristics of Perilla frutescens and Capsicum annuum leaves are measured to examine electrostatic effects according to the morphological features of trichomes. 3D settling motions of PMs near the microstructures of trichomes of the two plant species are compared in detail. To validate the PM removal effect of the hairy microstructures, a polydimethylsiloxane (PDMS) replica model of a P. frutescens leaf is fabricated to demonstrate accelerated settling velocities of PMs near trichome-like microstructures. The size and electric charge distributions of PMs with irregular shapes are analyzed using DIHM. Numerical simulation of the PM deposition near a trichome-like structure is conducted to verify the empirical results. As a result, the settling velocities of PMs on P. frutescens leaves and a PDMS replica sample are 12.11 ± 1.88% and 34.06 ± 4.19% faster than those on C. annuum leaves and a flat PDMS sample, respectively. These findings indicate that the curved microstructures of hairy trichomes of plant leaves increase the ability to capture PMs by enhancing the electric field intensity just near trichomes. Compared with conventional methods, the proposed methodology can quantitatively evaluate the settling velocity of PMs on various plant leaves according to the morphological structure and density of trichomes within a short period of time. The present research findings would be widely utilized in the selection of suitable air-purifying plants for sustainable removal of harmful air pollutants in urban and indoor environments.

Abstract: Continuous fire has a lot of plant and animal species to extinction, the Gov. has brought about little change apart from introducing a few forest mens and conducting a few surveys. But controls the forest fire is an exceptionally difficult task, but without the help of new technology. To remedy this, we are going to make a replica model of smart forest fire detection system that can help Gov. and Fire Authority in the monitoring and surveillance of forests fires. In our project, we have developed a forest fire detection and alert system. Our flame sensor is to detect the fire . The ESP 8266 is coded in a way that it on the GPS after detection of fire . connected Telegram dashboard will display the fire status on screen and alert the authorities. We have used NODE MCU(ESP 8266), GPS module. The NODE MCU gets fire detection input using the flame sensor, then using the GPS module it sends signal output to Telegram account. Next, using Telegram it processes the signal detection and shows respected output on screen. It then shows the result of the fire status of forest. All this information will saves on Telegram database for further analysis. So, in this way, our smart forest fire detection system keeps track on forest , detect fire and alert authorities on time and creates a database with previous fire statistics of the forest.

Targets for Renal Carcinoma Growth Control Identified by Screening FOXD1 Cell Proliferation Pathways.

Simple SummaryFOXD1 regulates the proliferation of clear cell renal cell carcinoma (ccRCC) cells, and ccRCC cells in which FOXD1 has been inactivated do not form tumors efficiently in an animal model. Reproducing growth inhibition in tumor cells by inhibiting FOXD1 pathways presents a possible therapeutic approach for ccRCC and other cancers. We have established an analysis strategy to identify FOXD1-regulated target pathways that may be therapeutically tractable, and compounds that modulate these pathways were selected for testing. Targets in three pathways were identified: FOXM1, PME1, and TMEM167A, which were inhibited by compounds FDI-6, AMZ-30, and silibinin, respectively. The effects of these compounds on the growth of tumor cells from patients cultured in a novel 3D tumor-replica culture environment revealed that FDI-6 and silibinin had strong growth inhibitory effects. This investigation informs new therapeutic targets to control ccRCC tumor growth, and provides a strategy to compare the responsiveness of individual patient tumor replicas to growth-inhibitory compounds.Clinical association studies suggest that FOXD1 is a determinant of patient outcome in clear cell renal cell carcinoma (ccRCC), and laboratory investigations have defined a role for this transcription factor in controlling the growth of tumors through regulation of the G2/M cell cycle transition. We hypothesized that the identification of pathways downstream of FOXD1 may define candidates for pharmacological modulation to suppress the G2/M transition in ccRCC. We developed an analysis pipeline that utilizes RNA sequencing, transcription factor binding site analysis, and phenotype validation to identify candidate effectors downstream from FOXD1. Compounds that modulate candidate pathways were tested for their ability to cause growth delay at G2/M. Three targets were identified: FOXM1, PME1, and TMEM167A, which were targeted by compounds FDI-6, AMZ-30, and silibinin, respectively. A 3D ccRCC tumor replica model was used to investigate the effects of these compounds on the growth of primary cells from five patients. While silibinin reduced 3D growth in a subset of tumor replicas, FDI-6 reduced growth in all. This study identifies tractable pathways to target G2/M transition and inhibit ccRCC growth, demonstrates the applicability of these strategies across patient tumor replicas, and provides a platform for individualized patient testing of compounds that inhibit tumor growth.

PIV measurement of turbulent flow characteristics inside an open-cell metal foam replica

Metal foam structures have been of interest because their geometrical characteristics are theoretically desirable to many applications such as heat exchanger, chemical reactor, filter, etc. Better understanding of flow characteristics inside metal foam is essential to utilize metal foam in thermo-fluid systems. A test section with a 3-D printed 8 times scaled-up transparent metal foam replica has been prepared. Time-resolved 2-D particle image velocimetry was used to measure velocity fields in the center planes at upstream, inside, and downstream of the replica model. The investigation was conducted for 3 different Reynolds numbers, 1000, 5,000 and 10,000 based on the channel hydraulic diameter. The turbulent flow characteristics inside an open-cell metal foam was compared between laminar and turbulent inlet flow conditions. Upstream turbulence intensity was 10% in case of turbulent inlet condition. For the ensemble averaged fields, clear similarities are found in mean velocity distributions and turbulent stresses inside the metal foam regardless of Reynolds number. The velocity magnitude inside metal foam increased up to 1.6 times of the channel bulk velocity for all Reynolds number. The temporal fluctuation of streamwise velocity component is increased up to 1.4 times to channel bulk velocity inside the metal foam replica. This increase was similar to that of laminar inlet condition even there is no fluctuations in the upstream. Normalized vorticity and turbulent kinetic energy also showed the similarity in three different Reynolds numbers, but the magnitude is higher at lower Reynolds number. Temporal analysis was also conducted at several points inside metal foam. The integral length scale is similar to 0.2 size of ligament in the case of Re = 10,000. Energy spectrum shows that the spectral slope is -5/3 in inertial subrange which confirm that flow inside metal foam is turbulent even the inlet flow is laminar.

Circuit Design for Predictive Maintenance

Industry 4.0 has become a driver for the entire manufacturing industry. Smart systems have enabled 30% productivity increases and predictive maintenance has been demonstrated to provide a 50% reduction in machine downtime. So far, the solution has been based on data analytics which has resulted in a proliferation of sensing technologies and infrastructure for data acquisition, transmission and processing. At the core of factory operation and automation are circuits that control and power factory equipment, innovative circuit design has the potential to address many system integration challenges. We present a new circuit design approach based on circuit level artificial intelligence solutions, integrated within control and calibration functional blocks during circuit design, improving the predictability and adaptability of each component for predictive maintenance. This approach is envisioned to encourage the development of new EDA tools such as automatic digital shadow generation and product lifecycle models, that will help identification of circuit parameters that adequately define the operating conditions for dynamic prediction and fault detection. Integration of a supplementary artificial intelligence block within the control loop is considered for capturing nonlinearities and gain/bandwidth constraints of the main controller and identifying changes in the operating conditions beyond the response of the controller. System integration topics are discussed regarding integration within OPC Unified Architecture and predictive maintenance interfaces,providing real-time updates to the digital shadow that help maintain an accurate, virtual replica model of the physical system.

The Raman laser spectrometer ExoMars simulator (RLS Sim): A heavy‐duty Raman tool for ground testing on ExoMars

AbstractThe Raman laser spectrometer (RLS) instrument onboard the Rosalind Franklin rover of the ExoMars 2022 mission will analyze powdered samples on Mars to search for traces of life. To prepare for the mission, the RLS scientific team has developed the RLS ExoMars Simulator (RLS Sim), a flexible model of RLS that operates similarly to the actual instrument, both in laboratory and field conditions, while also emulating the rover operational constraints in terms of sample distribution that are relevant to the Raman analysis. This system can operate autonomously to perform RLS‐representative analysis in one or several samples, making it very useful to perform heavy experimental tasks that would otherwise be impossible using a flight‐representative model of the instrument. In this work, we introduce the current configuration of the RLS Sim that has incorporated new hardware elements such as the RAman Demonstrator 1 (RAD1) spectrometer with the objective of approaching its performance to that of the actual RLS instrument. To evaluate the scientific capability of the RLS Sim, we have compared it with a replica model of RLS, the RLS Flight Spare (FS). Several acquisition aspects have been evaluated based on the analysis of select samples, assessing the performance in terms of spectral range and resolution and also studying several issues related to the evolution of signal‐to‐noise ratio (SNR) with different acquisition parameters, especially the number of accumulations. This performance analysis has shown that the RLS Sim in its updated configuration will be a key model to perform support science for the ExoMars mission and the RLS instrument on the Rosalind Franklin rover. Designed to work intensively, the use of the RLS Sim in combination with the RLS FS will facilitate maximizing the scientific return of the RLS spectrometer during Martian operations.

Efficiency of antlion trap design and larval behavior in capture success

Abstract Traps constructed by an animal reduce the amount of energy required to seek prey. The main risk of trap-building predators is the greater uncertainty of encountering prey, owing to their immobility. Sometimes environmental characteristics do not allow them to build efficient traps, resulting in lower capture success. We observed prey escape, capture success, and behavior of two antlion species, Cueta lineosa, a habitat specialist, and Myrmeleon hyalinus, a generalist, building geometrically different traps. The traps of C. lineosa are elaborate and deep, consisting of two inverted cones, while M. hyalinus builds simple inverted cones. Prey escape was observed from traps with antlion larvae present and from artificially constructed traps without antlions. We used a 3D printer to create a replica model of both trap types, pressing the model onto the substrate surface to create a trap. The C. lineosa artificial trap slowed prey escape more effectively than the simpler artificial trap of M. hyalinus. Prey escape time was four times longer for two ant species and three times longer for woodlice from C. lineosa traps. Escape time also decreased with increasing prey length. We also found behavioral differences between these two antlion species. The behavior of M. hyalinus is much more efficient in catching prey than that of C. lineosa. The results indicate that both species are efficient trap-building predators; however, it appears that capture success depends not only on trap design but also on larval behavior.

Protecting Decision Boundary of Machine Learning Model With Differentially Private Perturbation

Machine learning service API allows model owners to monetize proprietary models by offering prediction services to third-party users. However, existing literature shows that model parameters are vulnerable to extraction attacks which accumulate prediction queries and their responses to train a replica model. As countermeasures, researchers have proposed to reduce the rich API output, such as hiding the precise confidence. Nonetheless, even with response being only one bit, an adversary can still exploit fine-tuned queries with differential property to infer the decision boundary of the underlying model. In this article, we propose boundary differential privacy (BDP) against such attacks by obfuscating the prediction responses with noises. BDP guarantees an adversary cannot learn the decision boundary of any two classes by a predefined precision no matter how many queries are issued to the prediction API. We first design a perturbation algorithm called boundary randomized response for a binary model. Then we prove it satisfies <inline-formula><tex-math notation="LaTeX">$\epsilon$</tex-math><alternatives><mml:math><mml:mi>&#x03B5;</mml:mi></mml:math><inline-graphic xlink:href="zheng-ieq1-3043382.gif"/></alternatives></inline-formula>-BDP, followed by a generalization of this algorithm to a multiclass model. Finally, we generalize a hard boundary to soft boundary and design an adaptive perturbation algorithm that can still work in the latter case. The effectiveness and high utility of our solution are verified by extensive experiments on both linear and non-linear models.

Analisis Kekuatan Miniatur Sasis Bus Hasil Teknologi Fused Deposition Modelling dengan Metode Elemen Hingga

Replica is an imitation of an object that is scaled down to a specified scale. Replica manufacturing can be done by layer manufacturing technology so that it is more efficient and gets products similar to the originals. At present, the information about the results of the experimental testing process by computers on replica 3D models is still very limited. It is important to know that the replica have the expected quality. This study was conducted to determine the replica strength of the Hino RN 285 bus chassis 1:19 scale with PLA and AISI 1020 material. The calculations included stresses and deflections that occurred on the replica bus chassis due to the load from the replica cabin of 25.506 N. The study was conducted using Solidworks 2018 application for static load simulation process and for knowing the maximum stress and deflection that occurred. The simulation results obtained a maximum strenght value of 9,628 MPa. Deflection occurs at the front overhang, wheel base, and rear overhang with a maximum value occurs at the rear overhang of 0.7696 mm and causes stress distribution on the chassis frame of the rear overhang at 2.407 MPa. The maximum stress of the test results has a value smaller than the yield stress of the material and the deflection that occurs is below the critical deflection range, so it can be concluded that the replica model of the bus chassis is safe.

Effects of surface morphological structure of a brown alga miyeok (Undaria pinnatifida) on sustainable drag reduction

Liquid-infused surfaces are a promising passive technique for frictional drag reduction. However, their practical application is limited by the easy depletion of the lubricant infused in the surface by external forces. Miyeok contains mucus on its surface, which induces a sustainable slippery surface under flow conditions. In this study, the effect of the surface morphological structures of miyeok on slippery characteristics was examined. The surface of miyeok has bump-like microstructures and tiny pores of mucilage gland cells with a re-entrant inlet configuration. A replica model of the miyeok surface was fabricated by adopting a molding process using polydimethylsiloxane. The miyeok replica model was dipped into a silicone oil solution to obtain a slippery surface property. The surface structures of fresh miyeok and the replica were checked by comparing their scanning electron microscopy images. A replica of a kelp surface was also fabricated by employing the same method. The heights of the surface microstructures of the miyeok replica were more uniform than those of the kelp replica. The sustainable drag reduction effect of the replica models’ surfaces was assessed by a sessile drop method. The liquid-infused miyeok replica surface (LIMRS) showed better sustainability than other surfaces. The slippery properties of the LIMRS were examined by measuring slip length and pressure drop. The drag reduction rates measured by the two methods were approximately 24% and 19%. The present results would be helpful for understanding the effects of the surface structure of natural miyeok on sustainable drag reduction and developing a biomimetic sustainable drag-reducing surface.

Effect of expertise on TF adaptive system instrumentation quality in simulated mandibular molar canals.

The aim of the study was to examine the effect of operator experience on the quality of instrumentation of molar canals using the TF Adaptive file system (SybronEndo, Orange, CA) on a 3D-printed molar replica model. Three novice and two expert operators instrumented the root canals of three replicas each and resulting pre- and postinstrumentation 12 micron voxel size-microCT volumes of each replica were digitally registered. Relative modified canal wall surface fraction and canal transportation (1-9mm from the apex) were calculated and analysed by anova. Instrumentation by expert operators resulted in overall higher (P=0.002) modified wall surface fraction in the distal but not the mesial and higher (P=0.002) combined from all canal level transportation in the mesiobuccal canals but not the mesiolingual and distal canals. Instrumentation efficiency but also transportation using the TF Adaptive file system can be higher among expert, compared to novice, operators, depending on the canal type.

Theory of Flexible Polymer Networks: Elasticity and Heterogeneities.

A review of the main elasticity models of flexible polymer networks is presented. Classical models of phantom networks suggest that the networks have a tree-like structure. The conformations of their strands are described by the model of a combined chain, which consists of the network strand and two virtual chains attached to its ends. The distribution of lengths of virtual chains in real polydisperse networks is calculated using the results of the presented replica model of polymer networks. This model describes actual networks having strongly overlapping and interconnected loops of finite sizes. The conformations of their strands are characterized by the generalized combined chain model. The model of a sliding tube is represented, which describes the general anisotropic deformations of an entangled network in the melt. I propose a generalization of this model to describe the crossover between the entangled and phantom regimes of a swollen network. The obtained dependence of the Mooney-Rivlin parameters and on the polymer volume fraction is in agreement with experiments. The main results of the theory of heterogeneities in polymer networks are also discussed.

Similitudes for the structural response and radiated sound power of simply supported plates

This communication investigates exact and distorted similitudes and the related scaling laws for the analysis of both dynamic response and radiated power of rectangular plates. The response of a given panel in similitude from another one is determined from a generalization of the modal approach, allowing the use of mode shapes, natural frequencies and finally radiation functions in order to establish appropriate scaling laws. Analytical models of simply supported rectangular plates are used to produce both original and replica model responses under point mechanical excitation. Emphasis is then especially put on laboratory experiments which are performed on baed simply supported aluminum panels under mechanical excitations. All the six possible scaling directions, i.e., predicting a plate vibroacoustic reponse from another plate, are reported. All obtained results show that structural response or radiated sound power of a given plate can be both recovered with satisfactory accuracy by using the related scaling laws, even if parent models are used.
