http://www.surfacetreatments.it/thinfilms Automatic Electropolishing (Vanessa Rampazzo - 15') Speaker: Vanessa Rampazzo - Legnaro National Laboratories of INFN | Duration: 15 min. Abstract Electropolishing is an electrochemical process adopted in order to reduce the internal surface roughness. The process involves a special equilibrium between the reagents and the products, that creates a differential electrical resistance through the micrometric peaks and valleys of surface. This regime is detected collecting the current in function of voltage. Observing dinamically the changes of the characteristic curve during the process it’s possible to ensure the best electropolishing setting. The Dynamic Control of the best electropolishing point int I-V Plane is done by an automatic program, that collects continuoulsy the voltage and current and calculates in real time the best setting. Roughness smoothing is accompanied by the removal of anomalies on the surface, as pitting and stratches. The automatic program is written in Labview language and works on a industrial computer, a PLC.

This document discusses drugs used to treat ventricular tachyarrhythmias. It begins by describing cardiac electrophysiology, including the cardiac action potential and ion channels. It then discusses various classes of antiarrhythmic drugs, including class I drugs that block sodium channels, class II drugs that block beta-adrenergic receptors, class III drugs that prolong the action potential by blocking potassium channels, and class IV drugs that block calcium channels. The document emphasizes that while antiarrhythmic drugs can effectively treat arrhythmias, they may also cause arrhythmias as a side effect if not carefully monitored.Transistor 1 lecture
Transistors can be used as switches or amplifiers. The document discusses the basics of bipolar transistors including their structure, operation, and different configurations (common base, common emitter, common collector). It provides examples of calculating currents and voltages in transistor circuits using characteristics curves and explains how different classes of amplifiers (A, B, AB, C) determine the portion of the input signal cycle during which the transistor is active.
General Physiology - Cardiovascular sys.
Cardiac muscle fibers are striated like skeletal muscle but arranged in a latticework connected by intercalated discs. This allows cardiac muscle to function as a syncytium where action potentials can rapidly spread from cell to cell. The action potential in cardiac muscle is prolonged due to slow calcium channels remaining open, causing calcium and sodium influx and preventing early repolarization. This prolonged plateau allows for the longer contraction of cardiac muscle. Transverse tubules and sarcoplasmic reticulum release calcium ions during an action potential to trigger contraction via excitation-contraction coupling.
Electrical activity of heart
The document describes the anatomy and electrical activity of the heart. It notes that the heart is located in the chest, protected by membranes called the pericardium. The heart wall contains three layers - the epicardium, myocardium, and endocardium. The myocardium is the thick muscular layer and contains two types of cells - pacemaker cells that initiate electrical signals to trigger contractions, and contractile cells that make up the bulk of the heart muscle and contract in response to these signals. Pacemaker cells have an unstable membrane potential that causes them to spontaneously generate electrical impulses, while contractile cells remain at rest until stimulated by the pacemaker cells.
Cardiac+Electrophysiology
1. Cardiac electrophysiology involves the electrical activity in the heart, including the action potential and ion currents.
2. The cardiac action potential is initiated by the opening of fast sodium channels, followed by calcium and potassium channels.
3. Pacemaker cells in the sinoatrial node generate spontaneous action potentials due to a balance of slow inward calcium and funny currents and delayed outward potassium currents.
4. Action potentials propagate from pacemaker cells through the heart via gap junctions between cardiomyocytes. Propagation speed depends on the underlying ionic currents.
Conduction system and ecg
The document summarizes the cardiac conduction system and electrocardiogram (ECG). It describes how the conduction system initiates and propagates electrical signals throughout the heart to coordinate contractions. Specialized pacemaker cells in the sinoatrial node initiate signals that spread through atria and ventricles via pathways like the atrioventricular node and bundle of His. This electrical activity generates currents detectable by ECG, which can provide information on conduction abnormalities and heart health.

Dose calibrator
1) Dose calibrators are gas-filled ionization chambers used to measure the radioactivity of radionuclides by detecting the ionization current produced when radiation interacts with the gas.
2) They operate in the ionization chamber region where a constant voltage collects all ion pairs produced, allowing measurement of high activity levels without dead time effects.
3) Dose calibrators measure the total ionization current rather than individual energy events, so they cannot distinguish between radionuclides in mixed samples like solid scintillation counters can.

V. Palmieri - Superconducting resonant cavities
There is no dubt that the subject of superconducting resonant cavities is a fascinating field both physical and engineering point of view.
The application of superconductivity to the world of resonant cavities has made achievable results unimaginable otherwise.
Independently of the special field of application, superconducting resonant circuits have superior performances compared to roo-temperatire circuits.
However the greatest resource of such devices stays not in the high quality of the results already obtained, but in all potential applications and new ideas that must be still developed.
V. Palmieri - The classical superconductivity
When hearing about persistent currents recirculating for several year in a superconducting loop without any appreciable decay, we realize that we are dealing with a phenomenon wich in nature is the closest we know to the perpetual motion.
The zero resistivity and the perfect diamagnetism in Mercury at 4.2 K, the discovery of superconducting materials, finally the revolution of the "liquid Nitrogen superconductivity": Nature discloses drop by drop its intimate secrets.
Nobody can exclude that the final surpreise must still come.

This works deals with the A15 compound synthesis on niobium samples and over the
internal surface of niobium cavities by means of induction heating. Specifically, three compounds were studied: Nb3Ga, Nb3Al and Nb-Al-Ga. As for the preparation of the niobium samples, they were treated with BCP solution in order to polish the surface. The niobium cavities were treated with centrifugal tumbling, BCP solution and high pressure water rising. Subsequent, the samples, or cavities, were placed into an inductor controlling the voltage, time, sample position, temperature, type and pressure of gas used. The highest critical temperature
obtained was 18 K and Tc 0,35 K, in Nb-Al-Ga#1 sample by inductive measurement.
Mapping analysis showed the uniform diffusion of aluminum into the niobium, and the gallium diffuses creating channels into niobium. The composition was measured by EDS obtaining (82±1)% wt. Niobium, (11,3±0,9)% wt. Gallium, (4,7±0,2)% wt. Aluminum and (1,9±0,1)% wt. Oxygen. Finally, RF test confirmed that the cavities obtained after the annealing were normal conductive indicating that the preparation parameters must still be optimized.

In questi ultimi anni i problemi energetici e ambientali hanno favorito lo sviluppo di un nuovo settore della ricerca riguardo la produzione di energia pulita sfruttando fenomeni naturali. L'attenzione dei ricercatori è stata catturata dalla possibilità di convertire l'energia solare luminosa
in energia elettrica. Questo processo di conversione, nato nella prima metà del XX secolo, permette di produrre correnti elettriche anche in piccola scala, senza la realizzazione di imponenti impianti industriali e soprattutto senza la produzione si scorie inquinanti. Sono nate così le prime celle solari
a effetto fotovoltaico.
Gli sviluppi hanno portato a diversi risultati e al giorno d'oggi l'energia fotovoltaica ha ormai fatto il suo ingresso nella vita quotidiana. Sia i favori delle industrie, sia l'interesse dei privati cittadini, contribuiscono a espandere questo tipo di ricerca, ottenendo numerosi successi nell'aumento
dell'efficienza di conversione energetica. Dal punto di vista della scienza dei materiali la prima cosa che viene in mente pensando alle celle
fotovoltaiche è il silicio. A tutti gli effetti la maggior parte delle celle sul commercio sono costituite da silicio policristallino, per le sue ottime qualità e proprietà di resa. Tuttavia esistono anche una moltitudine di altri composti, alcuni più recenti di altri, che sono ancora nell'occhio dei ricercatori, un esempio ne sono i recenti foto-materiali organici. Spesso però i costi di realizzazione sono alti per ottenere rese elevate, rendendo così proibitive le realizzazioni su impianti industriali. L'ossido rameoso (Cu2O) è stato uno dei capostipiti dei materiali utilizzati nelle celle fotovoltaiche.
Fin dal suo primo utilizzo nel 1958 esso ha presentato le caratteristiche di semiconduttore necessarie alla realizzazione di impianti fotovoltaici. Rispetto ai sui cugini più nobili, presenta delle efficienze minori, ma anche un costo decisamente più basso. Il rame infatti, da innumerevoli anni, è un elemento largamente sfruttato in tutti i campi dell'elettronica e non solo, e la realizzazione di ossidi specifici non comporta processi troppo complessi o costosi.
La ricerca nel campo dell'ossido rameoso è riuscita a migliorare le sue qualità all'interno del mondo fotovoltaico rendendo possibile la realizzazione di celle solari a costi contenuti.
Per questo motivo il Cu2O è tutt'oggi un materiale in grado di competere nel moderno panorama della ricerca solare fotovoltaica.

Il plasma è un supporto particolarmente attivo dal punto di vista chimico e fisico. In base al modo con cui viene attivato e alla potenza di lavoro, può generare temperature basse o molto elevate e viene definito rispettivamente come plasma freddo o caldo. Quest’ampio range di temperature lo rende adatto a numerose applicazioni tecnologiche: rivestimento di superficie, smaltimento rifiuti, trattamento dei gas, sintesi chimiche, lavorazioni industriali. La maggior parte di queste applicazioni del plasma non sono ancora state industrializzate, sebbene il loro sfruttamento rispetti strettamente le norme sull’inquinamento.
I plasmi caldi (specialmente quelli ad arco) sono ampiamente industrializzati, con particolare diffusione all’interno del settore aereonautico. La tecnologia dei plasmi freddi è stata sviluppata in microelettronica, ma le apparecchiature da vuoto richieste ne limitano l’applicabilità.
Al fine di evitare l’inconveniente associato al vuoto, molti laboratori hanno provato a trasferire a pressione atmosferica processi che attualmente lavorano in vuoto. Le ricerche condotte hanno portato alla scoperta di varie ed innovative sorgenti che verranno descritte in questo elaborato.
Dopo un riassunto sui differenti tipi di plasmi, saranno descritte le varie sorgenti in termini di design, condizioni di lavoro e proprietà del plasma. In seguito l’attenzione sarà spostata sulle varie applicazioni (analisi spettroscopica, trattamento dei gas e processi sui materiali).

The lowest possible surface resistivity and higher accelerating field are the paramount
considerations, hence are obligatory for accelerating cavities. Since, superconducting materials
are used to make radio-frequency cavities for future accelerators. In the case of rf cavities,
superconductors are being used in order to minimize the power dissipated and increase the
figures of merit of a radio-frequency cavity, such as the quality factor and accelerating gradient.
Hence, these could be achieved by improving surface treatment to the cavity, and processing
techniques must be analyzed in order to optimize these figures of merit.
The research work reported in this dissertation mainly carried out on tesla type seamless 6GHz
Nb and Cu cavities. We have developed two innovative techniques: firstly, for mechanical
polishing of cavities, and secondly for purification of these cavities at atmospheric pressure under
cover of 4Helium gas (for protection) and at ultra-high vacuum (UHV) system. These cavities are
fabricated by spinning technology to create seamless cavities.
The main advantages of 6 GHz bulk-Nb cavities are saving cost, materials and time to collect
statistics of surface treatments and RF test in a very short time scale. Cavities are RF tested
before and after high temperature treatment under atmospheric pressure (under cover of inert gas
atmosphere to protect inner and outer surface of cavity) inside transparent quartz tube, and under
UHV conditions. Induction heating method is used to anneal the cavity at temperatures higher
than 2000°C and close to the melting point of Nb for less than a minute while few seconds at
maximum temperature. Before RF test and UHV annealing, the surface treatment processes like
tumbling, chemical, electro-chemical (such as BCP and EP), ultrasonic cleaning and high
pressure rinsing (HPR) have been employed. High temperature treatment for few minutes at
atmospheric pressure allow to reduce hydrogen, oxygen and other elemental impurities, which
effects on cavity Q-factor degradation, hence recovers rf performances of these cavities. This
research work will address these problems and illustrate the importance of surface treatments.

6 GHz spun seamless Superconducting Radio Frequency (SRF) cavities are a very
useful tool for testing alternative surface treatments in the fabrication of TESLA cavity.
However, the spinning technique has also some drawbacks like contamination, surface
damage in internal part due to the collapsible mandrel line. The first important step of
the surface treatments is the mechanical polishing. For this purpose, a new, cheap, easy
and highly efficient tumbling approach based on vibration was developed.
Before this approach was conceived, a few other methods, such as Turbula,
Centrifugal Barrel Polishing (CBP), custom Zigzag tumbler and “flower brush” have
been studied and tested. But the result was not so satisfactory neither for the low erosion
rate nor for the unstableness of the system nor for the complicated polishing process. At
last, a vibration system with a simple structure, working stably was created after two
experiments.
Another important task of the thesis is to update the optical inspection system for 6
GHz cavities. 3 stepper motors motor was added to move and rotate the cavity and
realized auto focus of the miniature camera. A software was developed to achieve a full
cavity photographed by one key operation using LabVIEW.
A high-efficiency mechanical polishing system is generally judged by two aspects:
one is whether the surface property satisfies the demand after polishing; the other is
whether the erosion rate can reach and be stabilized at a high value which is comparable
or greater than the existing products. The Radio Frequency (RF) test result indicates that
the vibration system is feasible. The latest erosion rate 1 gram/hour i.e. removing 13
microns depth of inner surface materials per hour exceeds the performance of CBP,
which is widely used in other laboratories in the world.
The mechanical polishing process is elaborated and cavities that have been polished
are listed. Several influencing factors on the erosion rate, such as tumbling time, media,
signal and multi-cavities and plate direction are discussed at the end.
A preliminary design of 1.3 GHz vibration system as the future development is
provided for the next plan.

Il forno in alto vuoto della TAV è stato costruito per l’Istituto Nazionale di Fisica Nucleare agli inizi degli anni novanta ed è installato presso i Laboratori Nazionali di Legnaro (PD) nello stabilimento Alte Energie.
E’ stato realizzato in collaborazione con la ditta milanese TAV, che ha sede a Caravaggio (MI), specializzata nella produzione di forni in vuoto. E’ stato così possibile realizzare un forno mai costruito prima e che rispondeva appieno alle esigenze richieste.
Il forno in vuoto allora in uso era un modello a caricamento orizzontale le cui pareti interne e le resistenze erano realizzate in grafite. Da allora il vecchio forno è stato congedato, mentre il nuovo impianto è entrato subito in funzione per eseguire le brasature e i trattamenti termici sulle cavità acceleratici superconduttive a quarto d’onda dell’impianto Alpi.
Da allora fino ad oggi, il nuovo forno è sempre stato operativo, e grazie ad esso è stato possibile realizzare una grande varietà di trattamenti termici e brasature, per le più svariate applicazioni e impieghi.

La tecnologia degli acceleratori di particelle è tradizionalmente un serbatoio da cui attingere per il trasferimento di conoscenze tecniche dall’ambito della ricerca di base all’industria; in questo campo i Laboratori Nazionali de Legnaro dell’Istituto Nazionale di Fisica Nucleare (LNL – INFN) vantano una lunga esperienza come ente di ricerca di alto livello sia in ambito italiano che internazionale, nello sviluppo di nuove tecniche di accelerazione e nell’applicazione di conoscenze e metodologie tipiche della scienza dei materiali al campo degli acceleratori di particelle. Il master in Trattamenti di superficie applicati a tecnologie meccaniche innovative per l’industria si inserisce in questo contesto e funge da ponte per il trasferimento del bagaglio di conoscenze maturate durante gli anni per il trattamento dei materiali delle cavità acceleratrici a realtà industriali presenti sul territorio nazionale.
Il trattamento superficiale di una cavità acceleratrice superconduttiva è un passaggio fondamentale nella sua realizzazione, in quanto predispone lo strato superficiale del risonatore stesso a sostenere le condizioni di vuoto, temperatura ed alti campi elettrici presenti durante il funzionamento nell’acceleratore; questi trattamenti presuppongono un’approfondita conoscenza della scienza dei materiali ed una robusta preparazione di tipo applicativo oltre che teorico.
Il lavoro di questa tesi prende l’avvio da due istanze fondamentali, cioè
dall’applicazione delle conoscenze fisiche, chimiche e meccaniche apprese nel corso del master e dalla tradizione nello sviluppo di nuove tecniche di accelerazione dei Laboratori Nazionali di Legnaro con il fine di realizzare e caratterizzare un nuovo tipo di strutture acceleranti basate sul concetto di cristallo fotonico o photonic band gap (PBG) applicato alle microonde.
Durante questo lavoro si sono quindi realizzati alcuni prototipi di cavità PBG risuonanti a 14 e 6 GHz, in rame ed in niobio superconduttivo, sviluppando un metodo realizzativo che permettesse di evitare il ricorso a costose saldature electron beam; le cavità così realizzate sono state trattate superficialmente adattando il protocollo di trattamento utilizzato per altre cavità costruite nei Laboratori e studiando nuove strade tecniche per la loro finitura superficiale. Infine si è proceduto ad adattare i sistemi criogenici e RF
integrandoli per caratterizzare le cavità costruite.Questo progetto si inserisce in una collaborazione fra i Laboratori Nazionali di Legnaro
e la sezione INFN di Napoli, che ha fornito il supporto teorico sulla teoria dei cristalli fotonici applicati agli acceleratori e ha contribuito al progetto delle cavità attraverso le simulazioni dei campi elettromagnetici in cavità; il gruppo di legnaro si è occupato, oltre che della costruzione, dei trattamenti di superficie e delle misure, anche della parte riguardante la superconduttività in Radiofrequenza.

L’obiettivo di questo lavoro consiste nella progettazione e costruzione di un sistema UHV multicamera per la deposizione di film sottili. La tecnica
utilizzata per crescere i ricoprimenti sottili in questo caso è l’arco catodico continuo e pulsato. Questa tecnica permette di depositare film di elevato spessore in tempi estremamente veloci. La sorgente è pressoché puntiforme in confronto allo sputtering ed i film possono essere più spessi e più puri.
L’arc vapour deposition è una tecnica di deposizione di film sottiliche cade nella grande famiglia del PVD. Essa consiste nella vaporizzazione, da un elettrodo, del materiale che si vuole depositare per mezzo di un arco. La tecnica è veloce, efficiente e relativamente poco costosa: di conseguenza è uno dei metodi più usati a livello industriale per ottenere deposizioni di film sottili con ottime proprietà meccaniche.
Negli ultimi anni si stanno effettuando numerose ricerche, sia sperimentali sia
teoriche, al fine di mettere in evidenza come questa tecnica possa essere molto utile per produrre dei film sottili in grado di aumentare le proprietà fisiche e chimiche dei rivestimenti (come ad esempio un aumento della densità, un miglioramento dell’adesione al substrato, della stechiometria dei composti e di ulteriori caratteristiche chimico-fisiche).
In particolare la letteratura russa tratta numerosi esempi di come la tecnica
dell’arco, proprio grazie all’alto grado di ionizzazione dei vapori prodotti, renda possibile la produzione di rivestimenti con determinate proprietà chimico-fisiche e strutturali per particolari condizioni di processo, non altrimenti ottenibili con altre tecniche competitive quali il magnetron sputtering o l’evaporazione tramite electron beam Come si vedrà in
seguito, infatti, l’arc vapour deposition ha il grandissimo vantaggio di controllare non solo la ionizzazione degli atomi che si vogliono depositare, attraverso una combinazione di campi elettrici e magnetici, ma anche l’energia con la quale gli ioni arrivano sul substrato.
Le sorgenti ad arco vengono inoltre utilizzate come sorgenti per LRQ EHDP che
devono produrre elevate densità di corrente.
Nel mondo industriale, infatti, questa tecnica riscuote molto interesse.Il deposito tramite arco catodico è un processo fisico sottovuoto che consente la
crescita di film duri, compatti ed aderenti su un ampio spettro di materiali al di sotto dei 300°C: Il film, estremamente sottile, ha durezze da 1000 a 3500 HV: le applicazioni industriali sono molte e variano dalla ricopertura di utensili da taglio agli tampi per le materie plastiche e lavorazioni meccaniche, da prodotti d’arredamento (maniglie, copri interruttori, pomoli, etc.) a componentistica da bagno (rubinetti, docce, tubi, etc.).

Fu una scoperta sensazionale quando Jun Akimitsu e colleghi annunciarono la loro scoperta nel gennaio 2001 che il diboruro di magnesio diveniva superconduttore attorno ai 40 K. L’interesse degli autori era inizialmente rivolto verso il semiconduttore CaB6 , il quale diviene ferromagnetico a seguito di trattamento leggero di doping. La loro intenzione era quella di sostituire parzialmente degli atomi di carbonio con altri di magnesio, omologo come shells elettronici ma più leggero, e gli parve conveniente utilizzare il diboruro di magnesio (ben noto sin dal 1953) per questo scopo.
L’aspetto interessante è che il magnesio diboruro è un composto molto usato nelle reazioni di sintesi del boro, dei borani, o di bururi di metalli di transizione e facilmente reperibile in qualsiasi laboratorio di chimica. E’ dunque facile immaginarsi lo stupore del mondo scientifico quando fu
comunicato che il MgB2 diviene superconduttore a temperature mai raggiunte sino ad allora da sistemi basati su semplici leghe intermetalliche non ossidate. Le fievoli speranze ed il derivante

High performance Serverless Java on AWS- GoTo Amsterdam 2024
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.What is an RPA CoE?

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
