description: The standard problem setting in cooperative multi-agent settings is self-play (SP), where the goal is to train a team of agents that works well together. However, optimal SP policies commonly contain arbitrary conventions ("handshakes") and are not compatible with other, independently trained agents or humans. This latter desiderata was recently formalized by Hu et al. 2020 as the zero-shot coordination (ZSC) setting and partially addressed with their Other-Play (OP) algorithm, which showed improved ZSC and human-AI performance in the card game Hanabi. OP assumes access to the symmetries of the environment and prevents agents from breaking these in a mutually incompatible way during training. However, as the authors point out, discovering symmetries for a given environment is a computationally hard problem. Instead, we show that through a simple adaption of k-level reasoning (KLR) Costa Gomes et al. 2006, synchronously training all levels, we can obtain competitive ZSC and ad-hoc teamplay performance in Hanabi, including when paired with a human-like proxy bot. We also introduce a new method, synchronous-k-level reasoning with a best response (SyKLRBR), which further improves performance on our synchronous KLR by co-training a best response.

description: Although many researchers have examined the effects of electroconvulsive therapy (ECT) on memory and cognition, few investigators have studied the  neurocognitive effects of bifrontal electrode placement in ECT treatment. The current study was designed to examine the clinical efficacy and neurocognitive  effects of bifrontal ECT. Participants included 17 adults between the ages of 23 and 62 years of age, all of whom had been diagnosed with unipolar or bipolar depression and met hospital criteria for ECT treatment, that is, had failed other treatment efforts. Recruitment of participants took place between 2009 and 2010 at a university-based psychiatric hospital. Following consent to participate and assurance that recruits met study criteria, a psychiatric interview was conducted and psychological/neuropsychological tests were administered. The tests were selected for the purpose of quantifying depressive symptoms and cognitive skills  thought to be affected by ECT (anterograde and retrograde memory, executive functions, and processing speed).  Results of the study demonstrated that bifrontal ECT can be an effective treatment of depression in that 88% of participants showed reduced depressive symptoms immediately after ECT treatment and 77% of these initial remitters continued to show response to treatment 1 month later. Although data also showed that the participants had posttreatment problems with retrograde  amnesia which had not resolved by follow-up 1 month later, and had impaired verbal fluency immediately posttreatment which remitted by follow-up, there  were no indications that the ECT treatment caused anterograde memory problems or other nonmemory cognitive problems. Specifically data showed no ill  effects of bifrontal ECT on processing speed and executive functions (inhibition, motor planning and response, sequencing, and cognitive flexibility). Without a  control group or randomized assignment to treatment, no firm conclusions can be drawn from the current findings; however, the findings are important in that  they suggest that bifrontal ECT treatment is as effective in addressing treatmentresistant depression as other ECT methods which entail electrode placements  that may produce greater and more persistent cognitive side effects, including bitemporal ECT.

description: The recent performance work of Ernesto Pujol complicates the notion of site-specific art, extending into the tension of what--or who--constitutes a site. This project considers Pujol's April 2010 site-specific performance entitled Awaiting as a case study in the decidedly complicated relationship between the discursive or fluid nature of the body and the constructed notion of place. Awaiting used performance to call attention to what Pujol identified as an unspoken but omnipresent "culture of waiting" in Utah. However, rituals of shared dress, gesture, and extended rhythms punctuated by spatial and temporal gaps simultaneously invoked and transformed the cultural, historical, and social landscape in which Awaiting was situated.   Looking to the various uses of gesture and mapping within Awaiting, I argue that Pujol's invocation of "site" prevented him from creating a space that matched his  intention to transcend the constructed nature of site. Rather, the embodied representations of Salt Lake's local identity infiltrated and transformed Awaiting. Consequently, I use Pujol's intentionality in Awaiting as a foil to examine the possibilities and limitations of  site-specific performance. I conclude that Awaiting's site-specificity originates not only in its allusion to a culture of waiting, but rather in its resemblance to a ritualistic history characteristic of Utah starting with the definitive utterance of "this is the place."

description: Fragmentation processes of uridine-(TMS)(,4) were investigated using selectively deuterium and ('18)O labeled uridine. Decomposition pathways of uridine-(TMS)(,4) were measured by two metastable ion techniques, and plausible ion structures have been deduced from isotopic labeling data and mechanistic considerations. In addition, 128 silylated nucleoside mass spectra were examined to detect common characteristics for each class of nucleosides, for example, C-C versus C-N glycosidic bond, purine versus pyrimidine nucleosides, and (alpha) versus (beta) anomer. An Application of the knowledge of nucleoside fragmentation processes was shown by the structural characterization of a modified nucleoside isolated from Halococcus morrhuae tRNA. The utility of this knowledge for establishing the location of substituents and isotopic labels in the nucleoside skeleton was also described.  The use of high resolution mass spectrometry to analyze and identify nucleoside components in tRNA hydrolysates was studied. The optimal experimental conditions: method of ionization, rate of heating the sample without defocusing the ion source, the resolution required to unequivocally determine the existence of a modified nucleoside in the hydrolysates, the sensitivity of this methodology, and the tradeoff between resolution and sensitivity were investigated and described. The procedures involved for the analysis of the high resolution mass spectrometric data were discussed in detail. Using E. coli tRNA('Phe) and tRNA('Glu) as models, modified nucleosides which occur only once in the tRNAs were identified with as little as 1 (mu)g of the tRNA hydrolysate. Resolution of 20,000 (10% valley definition) was found to be the best for the analysis of tRNA hydrolysate mixtures in terms of both resolution and sensitivity. The applications of this methodology were shown by the identification of N-{(9-(beta)-D-ribofuranosyl)-2-methylthiopurin-6yl-carbamoyl}threonine in tRNA(,1)('Lys) and tRNA(,3)('Lys) of B. subtilis. The procedure and application of this technique for the analysis of tRNAs of unknown components were also described with a tRNA('Leu) isolated from Morris hepatoma as an example.

description: Diphosphoglycerate (DPG) plays an integral part in the transport of oxygen to tissues.  By binding reversibly with hemoglobin, DPG decreases hemoglobin's affinity for oxygen and increases oxygen availability to the tissues.  Multiple factors affect the synthesis and binding ability of DPG and indirectly alter oxygen availability to the tissues.  General aesthesia imposes many physiologic alterations which, when considered individually, are known to alter DPG levels.  The purpose of the present study was to quantify, describe, and compare the preoperative and postoperative measurements of DPG levels in non-acute patients undergoing anesthesia.  DPG levels on 30 healthy adults (19 females and 11 males) were obtained before and after elective surgery under general anesthesia.  DPG levels decreased from a preoperative mean of 2.34 um-mols/ml to a postoperative mean of 1.83 um-mols/ml (p
Corrosion resistant concrete using corrosion resistant steel

Corrosion

description: Corrosion of reinforced concrete is a major concern in the United States infrastructure. It is possible to create corrosion resistant concrete structures through careful evaluation of the environmental and mechanical demands on the structure and by selecting appropriate materials to meet those demands. Designers, owners, contractors, and suppliers can work together to produce a concrete capable of withstanding the harsh demands of today and the future. Specifying a ternary mixture with fly ash and slag will produce a less permeable concrete which will both extend the time to corrosion initiation and decrease the rate of propagation. Furthermore, using reinforcing less susceptible to corrosion will extend the service life of the structure. Epoxy coated rebar provides a protective coating for the steel to prevent corrosion. This research seeks to demonstrate the effectiveness of using a ternary blend in conjunction with epoxy coated rebar in helping to decrease the odds of corrosion by reducing permeability and providing a protective coating for the reinforcing.

Wiederholbarkeit

description: Im Verlauf des Jahres 2021 wurden nach Schätzungen des BSW-solar rund 141.000 PVHeim-Speichersysteme in Deutschland in Betrieb genommen und rund 54% der neu installierten PV-Anlagen bis zu einer Nennleistung von 10 kW wurden mit Speichern ausgerüstet [1]. Damit hat sich die Anzahl der neu installierten Heim-Speicheranlagen gegenüber dem Vorjahr um ca. 60% erhöht. Diese Systeme werden hauptsächlich in Privathaushalten zur Steigerung des Eigenverbrauchs eingesetzt. Um den Anlagenbetreibern den wirtschaftlichen Nutzen zu sichern, der wesentlich auf der Differenz zwischen Strombezugspreis und Einspeisevergütung beruht, ist ein hocheffizientes PV-Speichersystem von grundlegender Bedeutung. Aus Sicht der Verbraucherinformation sollte die Effizienz der PV-Heim-Speichersysteme außerdem allgemeinverständlich und gut nachvollziehbar dargestellt werden können. Aus dieser Motivation heraus hat ein Konsortium aus Forschungs- und Prüfinstituten sowie Herstellern aus Deutschland, Österreich und der Schweiz unter der Koordination der Verbände BVES und BSW-solar den „Effizienzleitfaden für PV-Speichersysteme“ erarbeitet, dessen zweite Version in deutscher und englischer Fassung im Juli 2019 veröffentlicht wurde [2]. Der Effizienzleitfaden beinhaltet eine detaillierte Effizienzbetrachtung von Speichersystemen mit Testspezifikationen u.a. zur Bestimmung der Batterieleistung, der Effizienz der Leistungselektronik und der Energiewandlungspfade, des statischen und dynamischen Regelverhalten, des Standby-Verbrauchs. Aktuell wird der Effizienzleitfaden im Rahmen des DKE-Arbeitskreises 371.0.9 „Kennwerte von stationären Batteriespeichern“ zu einer Norm weiterentwickelt. Systematische Vergleiche auf Basis der Messungen gemäß Effizienzleitfaden sind nur sinnvoll, wenn die Messungen und ihre Auswertungen auch wiederholbar und reproduzierbar sind. Die Wiederholbarkeit von Messungen auf demselben Prüfstand wurde bereits untersucht [3]. Wichtig ist jedoch, dass die Messergebnisse auch reproduzierbar sind, wenn die Tests an unterschiedlichen Instituten durchgeführt bzw. ausgewertet werden. Andernfalls können Unterschiede in den Ergebnissen zu Inkonsistenzen bei der Bewertung der Systeme führen. Das F+E-Projekt „Testbench“ unterstützt die Weiterentwicklung des Effizienzleitfadens insbesondere in Hinblick auf die Reproduzierbarkeit der Tests bei unterschiedlichen Prüfinstituten. Erste Erkenntnisse werden hier vorgestellt.

description: America has a lengthy history with irregular warfare. The nation was born of an insurgency and remained committed to such conflict over the centuries, from the American Revolution in the eighteenth century, the Indian Wars in the nineteenth century, the Philippines in the twentieth century, and Iraq and Afghanistan in the twentieth-first century. Although the U.S. has learned a great deal from centuries of fighting irregular war, the lessons were continuously learned and forgotten, indicating America‘s distaste of such conflict. Yet, as America continues to fight irregular wars, doctrine and policy have taken shape. However, whereas doctrine and policy may exist, our practices remain very similar to the past, often involving inconsistent and ad hoc measures. Yet, new methodology emerged which takes ?best practices? from centuries of irregular war. This methodology calls for a fundamental change in how the U.S. approaches irregular war, illustrating the need to focus on local level instability and conflict drivers. Further, this methodology not only can be employed in the field of conflict, but also can help mitigate conflict before it becomes war. In order to learn from America‘s history in irregular war, and embrace methodology based on historical ?best practices,? America must move from merely changing its policy to changing how it practices irregular conflict.    Dedicated to my wife, Hamida Alexander, for enduring my days and nights away while she tirelessly performed the bulk of the parenting.

description: More than 285,000 total hip replacement (THR) surgeries are performed in the United States each year. Most prosthetic hip joints consist of a cobalt-chromium (CoCr) femoral head that articulates with a polyethylene acetabular component lubricated with synovial fluid. The statistical survivorship of these metal-on-polyethylene prosthetic hip joints declines significantly after 10 to 15 years of use, primarily as a result of polyethylene wear and wear debris incited disease. The current engineering paradigm to increase the longevity of prosthetic hip joints is to manufacture ultra-smooth articulating surfaces. In contrast, this work shows that adding a patterned microtexture to the ultra-smooth CoCr femoral head reduces friction when articulating with the polyethylene acetabular liner. The microtexture increases the load-carrying capacity and the thickness of the joint lubricant film, which reduces contact between the articulating surfaces. As a result, friction and wear is reduced. A lubrication model is used to design the geometry of the patterned microtexture, and we experimentally demonstrate reduced friction for the microtextured compared to conventional smooth surrogate prosthetic hip joints.

description: Schoolwide Positive Behavior and Supports (SWPBS) are being used in thousands of schools throughout the United States with many positive results, including decreased office discipline referrals and increased teaching time. While many of the benefits of SWPBS have been demonstrated, the question of its social validity from the  student perspective has yet to be address. This study examines the social validity of SWPBS from the student perspective and assesses the usefulness of two instruments, the ABC Student Survey (ABC) and ABC-UBI Social Validity Interview (SVI), designed to  addresses the social validity of SWPBS from the student perspective. The ABC was administered to 3835 students across eight Utah schools and the SVI was administered to 105 students across the same eight schools. The results of both measures were examined to determine the social validity of SWPBS and the acceptability of the psychometric properties of the two measures. The results indicate that in general, students strongly  endorsed the social validity of SWPBS. Students tended to endorse the theoretical components of SWPBS more than the practical components. The results of the  assessments of the ABC and SVI indicate that the ABC is an adequate measure of the general social validity of SWPBS while the SVI is at present an inadequate measure of the specific components of social validity and SWPBS.

description: The federated learning (FL) framework enables edge clients to collaboratively learn a shared inference model while keeping privacy of training data on clients. Recently, many heuristics efforts have been made to generalize centralized adaptive optimization methods, such as SGDM, Adam, AdaGrad, etc., to federated settings for improving convergence and accuracy. However, there is still a paucity of theoretical principles on where to and how to design and utilize adaptive optimization methods in federated settings. This work aims to develop novel adaptive optimization methods for FL from the perspective of dynamics of ordinary differential equations (ODEs). First, an analytic framework is established to build a connection between federated optimization methods and decompositions of ODEs of corresponding centralized optimizers. Second, based on this analytic framework, a momentum decoupling adaptive optimization method, FedDA, is developed to fully utilize the global momentum on each local iteration and accelerate the training convergence. Last but not least, full batch gradients are utilized to mimic centralized optimization in the end of the training process to ensure the convergence and overcome the possible inconsistency caused by adaptive optimization methods.

Mandelbrojt and becomes useful and necessary when working with corresponding classes of ultradifferentiable functions defined via weight sequences and analogous weighted spaces. In this note we also study non-standard situations for the construction yielding the (log-)convex minorant of a sequence and allow a "blow-up" for the regularizing function.

description: The goal of this project was to study a control system and prototype for a wearable lift assist device. The purpose of this device is to support the upper body during torso flexion and extension to reduce the erector spinae muscle activity and decrease back compressive force. It could also be used in rehabilitation or return to work scenarios after back injury or surgery. The proposed device is actively controlled and able to provide support based on the wearer's position, anthropometry, and desired level of assist. The upper body is supported by direct current (DC) motors and bilateral torsion springs. The assist level is a function of the percentage of torque needed to statically support the torso for a given angle and can range from 0 to 100%. To develop and test the control system, an electromechanical system was developed to simulate the human torso during lifting. The torso and support mechanism were driven by separate DC motors and drive trains. The torso and support of the mechanism were operated independently, as would be required of an actual assist device. The support control used a position sensor to approximate torso angle and a load cell to determine if the correct amount of torque was applied. The load cell also served to measure the amount of actual assistance provided and gave feedback to the control system. The support control system and mechanism were evaluated using three angular trajectories, derived from actual lifting data. The measured trajectory of the torso with no assist was compared at each level (20 - 100%, in increments of 10%). Ten percent was not analyzed because the support system was unstable at such a low assist level. The torso's trajectory, load cell measurements, and torque produced by the motor driving the torso were analyzed to determine performance. There was a statistical difference when comparing the torso's trajectory with no assist to each level of assist (t < 0.0001) but may not be practically different. No statistical difference was found when comparing the load cell measurement to the target value for each trial (t > 0.05). The torque produced by the torso motor was reduced for all trials and were statistically different (t < 0.0001).  This study demonstrates that a mechanism can be actively controlled to provide assistance during lifting. A feasible control system was developed and tested. System stability and mechanical losses in the apparatus were the primary sources of error. Further work on active lifting assist devices and studies to determine actual benefits to users is warranted. The next step is to develop a wearable prototype and explore the benefits of using it in rehabilitation, and low back pain relief.

description: Variational quantum algorithms (VQAs) are among the most promising algorithms to achieve quantum advantages in the NISQ era. One important challenge in implementing such algorithms is to construct an effective parameterized quantum circuit (also called an ansatz). In this work, we propose a single entanglement connection architecture (SECA) for a bipartite hardware efficient ansatz (HEA) by balancing its expressibility, entangling capability, and trainability. Numerical simulations with a one-dimensional Heisenberg model and quadratic unconstrained binary optimization (QUBO) issues were conducted. Our results indicate the superiority of SECA over the common full entanglement connection architecture (FECA) in terms of computational performance. Furthermore, combining SECA with gate-cutting technology to construct distributed quantum computation (DQC) can efficiently expand the size of NISQ devices under low overhead. We also demonstrated the effectiveness and scalability of the DQC scheme. Our study is a useful indication for understanding the characteristics associated with an effective training circuit.

Transit signal priority

description: Traffic congestion is an increasing problem in most urban areas in the United States. One of the sources of this problem is the automobile-oriented development that encourages automobile use and suppresses other transportation modes. A good transit system can satisfy most of the requirements of a transportation system user. A transit system must be efficient, safe, comfortable, and competitive to private cars in order to attract more riders. Transit Signal Priority (TSP) is an operational strategy that facilitates transit vehicles at signalized intersections. It improves transit efficiency and helps transit offer travel times competitive to private cars. A lot of studies conducted in the past 40 years show the major possibilities and benefits of TSP. The goal of this research is to develop a simulation-based methodology for the evaluation and improvement of TSP strategies. The objectives consist of evaluating existing and future TSP systems, and developing field-ready algorithms that provide adaptive ways for achieving different levels of TSP and improving its operation. The focus of the research is on using traffic microsimulation to evaluate and improve TSP, but it also looks into some field-based implementations and evaluations for additional support. The analysis of different TSP strategies is performed on existing and future rapid transit mode implementations, namely Bus Rapid Transit (BRT) and Light Rail Transit (LRT). The results from the presented studies show the major benefits of TSP implementations for transit operations and small disruptions for vehicular traffic. Depending on the selected strategies and level of TSP, the travel time savings for transit can be between 10% and 30%, the reduction in intersection delay can exceed 60%, while running time reliability and headway adherence are greatly improved. These improvements in transit operations can make transit more efficient and competitive to private cars, justifying the TSP implementation. This research offers significant contributions to the state of TSP practice and research. It provides detailed insights into TSP operations, develops methods for its evaluation, and describes algorithms for achieving different levels of TSP. A significant part of the research is dedicated to the use of Software-in-the-Loop (SIL) traffic controllers in microsimulation. Through this research, SIL is proven to be a powerful tool for simulating complex traffic signal operations and TSP.

description: A drop exposed to cross flow of air experiences sudden accelerations which deform it rapidly ultimately proceeding to disintegrate it into smaller fragments. In this work, we examine the breakup of a drop as a bag film with a bounding rim resulting from acceleration induced Rayleigh-Taylor instabilities and characterized through the Weber number, \textit{We}, representative of the competition between the disruptive aerodynamic force imparting acceleration and the restorative surface tension force. Our analysis reveals a previously overlooked parabolic dependence ($\sim We^2$) of the combination of dimensionless instability wavelengths $({\barλ}_{bag}^2/ {\barλ}_{rim}^4 {\barλ}_{film})$ developing on different segments of the deforming drop. Further, we extend these findings to deduce the dependence of the average dimensionless drop sizes for the rim, $\langle{\bar{D}}_{rim}\rangle$ and bag film, $\langle{\bar{D}}_{film}\rangle$ individually, on $We$ and see them to decrease linearly for the rim ($\sim We^{-1}$) and quadratically for the bag film ($\sim We^{-2}$). The reported work is expected to have far-reaching implications as it provides unique insights on destabilization and disintegration mechanisms based on theoretical scaling arguments involving the commonly encountered canonical geometries of a toroidal rim and a curved liquid film.

description: Current technology and theoretical methods are allowing for the detection of sub-Earth sized extrasolar planets. In addition, the detection of massive moons orbiting extrasolar planets ("exomoons") has become feasible and searches are currently underway. Several extrasolar planets have now been discovered in the habitable zone (HZ) of their parent star. This naturally leads to questions about the habitability of moons around planets in the HZ. Red dwarf stars present interesting targets for habitable planet detection. Compared to the Sun, red dwarfs are smaller, fainter, lower mass, and much more numerous. Due to their low luminosities, the HZ is much closer to the star than for Sun-like stars. For a planet-moon binary in the HZ, the close proximity of the star presents dynamical restrictions on the stability of the moon, forcing it to orbit close to the planet to remain gravitationally bound. Under these conditions the effects of tidal heating, distortion torques, and stellar perturbations become important considerations to the habitability of an exomoon. Utilizing an evolution model that considers both dynamical and tidal interactions, I performed a computational investigation into long-term evolution of exomoon systems. My study focused on satellite systems in the HZ of red dwarf stars and the dependence of exomoon habitability on the mass of the central star. Results show that dwarf stars with masses < 0.2 M© cannot host habitable exomoons within the stellar HZ due to extreme tidal heating in the moon. These results suggest that a host planet could be located outside the stellar HZ to where higher tidal heating rates could act to promote habitability for an otherwise uninhabitable moon. Perturbations from a central star may continue to have deleterious effects in the HZ up to « 0.5 MSun, depending on the host planet's mass and its location in the HZ. In cases with lower intensity tidal heating, stellar perturbations may have a positive influence on exomoon habitability by promoting long-term heating rates above a minimum for habitable terrestrial environments. In addition to heating concerns, torques due to tidal and spin distortion can lead to the relatively rapid inward spiraling of a moon. The effects of torque and stability constraints also make it unlikely that long-term resonances between two massive moons will develop in the HZs around red dwarf stars. My study showed that moons in the circumstellar HZ are not necessarily habitable by definition. In addition, the HZ for an exomoon may extend beyond the HZ for an exoplanet. Therefore, an extended model is required when considering exomoon habitability in comparison to exoplanet habitability.

description: Stochastic reaction network models arise in intracellular chemical reactions, epidemiological models and other population process models, and are a class of continuous time Markov chains which have the nonnegative integer lattice as state space. We consider the problem of estimating the conditional probability distribution of a stochastic reaction network given exact partial state observations in time snapshots. We propose a particle filtering method called the targeting method. Our approach takes into account that the reaction counts in between two observation snapshots satisfy linear constraints and also uses inhomogeneous Poisson processes as proposals for the reaction counts to facilitate exact interpolation. We provide rigorous analysis as well as numerical examples to illustrate our method and compare it with other alternatives.

description: Political scientists believe that the Abu Sayyaf Group's (ASG) penchant for accumulating funds through hostage ransoming and other criminal activity has caused the  organization to drift away from its Islamic foundations to become bandits. This research explores this claim by applying geospatial analysis to ASG terrorist activity to evaluate if ASG attack data are congruent with original political objectives or more suited to profitdriven  criminal patterns of activity.  Four research objectives are used that explore if attack data display an operational shift. The first three compare data distribution to map overlays of economic level,  ethnicity and religion to identify where attack majorities occur. This identifies if the ASG is prone to attacking areas populated by their constituency. The fourth objective examines the history of the ASG by comparing it to terrorist ideological transformation theory. The  results of these objectives are combined in the decision rule to evaluate if ASG data supports the claims of a philosophical shift. Applied methods include spatio-temporal analysis and geostatistics (hot spot analysis and mean center progression).  Results of analysis indicate that the majority of ASG attacks occur in a trivariate convergence area of map overlays. Temporal analysis shows that attacks localized and peaked around the Constituency Overlay in accordance with benchmarks for a terror-to-crime  shift. It is concluded that the majority of ASG attacks are driven towards crime due to a high frequency of moneymaking attacks within areas of constituency. Based on the decision rule, the patterns of attack data indicate that ASG operations have been more inclined towards criminal goals since the death of their founder, Abdurajak Janjalani.

description: One of the most enticing research areas is the stock market, and projecting stock prices may help investors profit by making the best decisions at the correct time. Deep learning strategies have emerged as a critical technique in the field of the financial market. The stock market is impacted due to two aspects, one is the geo-political, social and global events on the bases of which the price trends could be affected. Meanwhile, the second aspect purely focuses on historical price trends and seasonality, allowing us to forecast stock prices. In this paper, our aim is to focus on the second aspect and build a model that predicts future prices with minimal errors. In order to provide better prediction results of stock price, we propose a new model named Long Short-Term Memory (LSTM) with Sequential Self-Attention Mechanism (LSTM-SSAM). Finally, we conduct extensive experiments on the three stock datasets: SBIN, HDFCBANK, and BANKBARODA. The experimental results prove the effectiveness and feasibility of the proposed model compared to existing models. The experimental findings demonstrate that the root-mean-squared error (RMSE), and R-square (R2) evaluation indicators are giving the best results.

description: È possibile ripercorrere la lunga storia del diritto privato sotto l’insegna (e quindi alla ricerca) della sua ‘funzione sociale’? Betti identificò la causa negoziale appunto nella funzione sociale ma la idea ha un’ampiezza e una storia assai più ampia. La dibattuta stesura dell’art. 42 della Costituzione è emblematica. La funzione sociale nel diritto privato può allora essere una chiave di lettura, un filo conduttore che ci aiuti a comprendere il senso di una lunga riflessione che ha caratterizzato la scienza civilistica moderna nelle sue molte articolazioni.
