REDISCOVERING CULTURAL HERITAGE SITES BY INTERACTIVE 3D EXPLORATION: A PRACTICAL REVIEW OF OPEN-SOURCE WEBGL TOOLS

Abstract. Georeferenced reconstructions can help understand the dynamic evolution of the urban context surrounding a historical site, supporting decision-making processes in the field of urban planning. The development of web applications that allow the interaction between 2D and 3D products, as well as their exploration, can facilitate virtual inspections and foster collaboration in digitization of interventions and site evolutions over time. The article discusses how virtual scene reconstructions and visits can provide alternatives to traditional in-situ tourism promotion, through digital storytelling solutions for the exploration of sites. The article also describes how 3D storytelling technologies are currently being used for dissemination cultural heritage sites. The case study of the Castello Farnese, an old XVI century heritage site in Piacenza (Italy), test the adoption of two distinct free and open-source JavaScript WebGL, Potree and Cesium, for the rendering of photogrammetric and laser scanning georeferenced scaled products and for the integration of narrative features such as annotations, camera animations, texts, and other multimedia contents. Potentials and limitations of both tools are discussed in detail, highlighting how they can be implemented for enhancing user experience in virtual tour and exploration of 3D products. In order to guarantee replicability for other case studies, source code of the implemented application is shared on GitHub along with its documentation for contributions.

A lightweight remote attestation using PUFs and hash-based signatures for low-end IoT devices

Remote attestation is a powerful mechanism that allows a verifier to know if the hardware of an IoT (Internet-of-Thing) device (acting as a prover) has been counterfeited or tampered with and if its firmware has been altered. Remote attestation is based on collecting and reporting measurements in a trusted way, and should be lightweight for resource-constrained IoT devices. This work proposes to include a low-cost Root of Trust for Measuring and Reporting (RoTMR) in the prover, based on the combination of a Physically Unclonable Function (PUF) and an Attestation Read-Only Memory (A-ROM), and to use hash-based digital signatures in the attestation protocol. The proposed RoTMR is addressed to IoT devices based on a microcontroller that executes some application code (the measurable object) located in an external non-volatile memory accessible by an attacker. The secret keys required by the digital signatures are not stored but reconstructed using the PUF. The A-ROM contains the attestation instructions and ensures that its contents cannot be altered and that its instructions are executed sequentially without modification. The use of hash-based digital signatures makes the solution quantum-resistant and very robust because its security relies solely on the unidirectionality of a hash function. The proposed attestation protocol takes advantage of the fact that One-Time Signature (OTS) generation and Many-Time Signature (MTS) verification are very well suited for low-end devices, and the MTS scheme is suitable for the verifier application context. The proposal was validated experimentally with the ESP32 microcontroller, which is widely employed in IoT devices, by using its SRAM as PUF and implementing WOTS+, which is a type of Winternitz One-Time Signature scheme (WOTS), the One-Time Signature of Smart Digital Signatures scheme (SDS-OTS), and the MTS schemes constructed with them. The OTS schemes require smaller codes and thus smaller A-ROM than MTS and ECDSA (Elliptic Curve Digital Signature Algorithm). The code of one of the WOTS+ takes about 4 times less space than ECDSA. In terms of execution times, the OTS schemes are very fast. One of the WOTS+ performs all the signature operations in a few tens of milliseconds. The OTS schemes (especially the SDS-OTS) are also very efficient in terms of communication bandwidth because they use small signatures compared to other post-quantum solutions.

Ad Hoc Transactions: What They Are and Why We Should Care

Many transactions in web applications are constructed ad hoc in the application code. For example, developers might explicitly use locking primitives or validation procedures to coordinate critical code fragments. We refer to database operations coordinated by application code as ad hoc transactions. Until now, little is known about them. This paper presents the first comprehensive study on ad hoc transactions. By studying 91 ad hoc transactions among 8 popular open-source web applications, we find that (i) every studied application uses ad hoc transactions (up to 16 per application), 71 of which play critical roles; (ii) compared with database transactions, concurrency control of ad hoc transactions is much more flexible; (iii) ad hoc transactions are error-prone-53 of them have correctness issues, and 33 of them are confirmed by developers; and (iv) ad hoc transactions have the potential to improve performance in contentious workloads by utilizing application semantics such as access patterns. Finally, implications of ad hoc transactions to the database research community are discussed.

Reduced complexity XOR trees for LDPC codes and BS-LFSR techniques to High-Speed memory applications

Low-Density Parity Check (LDPC) Codes exhibit dominant role which deal with limitation of storage capacity. Hardware realization of Parity Check Codes is slow and consumes more power which makes it vulnerable for the light weight applications. Hence, to improve the throughput, area and power dissipation, parity check architectures must be constrained. This article proposes architecture of LDPC codes for high-speed memory applications with comparable XOR-gate tree-based VLSI design. The designed extension module includes Bit Swapping Linear Feedback Shift Register (BS-LFSR) technique that can illustrate and gauge expansion of faults in both the versions of faulty and fault-free. Furthermore, the power dissipation has been reduced by 8% and area by 83% with its extension module. This work has been designed using Vivado HLS and the hardware implementation of BS-LFSR has been verified on Zync 7000 series FPGA board for faulty and fault-free test patterns.

SLocator: Localizing the Origin of SQL Queries in Database-Backed Web Applications

In database-backed web applications, developers often leverage Object-Relational Mapping (ORM) frameworks for database accesses. ORM frameworks provide an abstraction of the underlying database access details so that developers can focus on implementing the business logic of the application. However, due to the abstraction, developers may not know where and how a problematic SQL query is generated in the application code, causing challenges in debugging database access problems. In this paper, we propose an approach, called SLocator, which locates where a SQL query is generated in the application code. SLocator is a hybrid approach that leverages both static analysis and information retrieval (IR) techniques. SLocator uses static analysis to infer the database access for every possible path in the control flow graph. Then, given a SQL query, SLocator applies IR techniques to find the control flow path (i.e., a sequence of methods called in an interprocedural control flow graph) whose inferred database access has the highest similarity ranking. We implement SLocator for Java's official ORM API specification (JPA) and evaluate SLocator on seven open source Java applications. We find that SLocator is able to locate the control flow path that generates a SQL query with a Top@1 accuracy ranging from 37.4% to 70% for SQL queries in sessions, and 30.7% to 69.2% for individual SQL queries; and Top@5 ranging from 78.3% to 95.5% for SQL queries in sessions, and 59.1% to 100% for individual SQL queries. We also conduct a study to illustrate how SLocator may be used for locating issues in the database access code.

Systematic review on blockchain research for sustainability accounting applying methodology coding and text mining

Blockchain and other Distributed Ledger Technologies (DLTs) are often considered major improvements in the capability of certain areas in sustainability accounting research. As such, it is argued that blockchains could be used for validation, data management, transactions settlements and objective measurement for corporate sustainability indicators, such as Greenhouse Gas (GHG) emissions during production processes. Following a Systematic Literature Review (SLR) methodology in data collection and database formation, the current work provides an analysis of the existing literature consisting of 59 contributions on blockchain applications in sustainability accounting. Several analysis steps containing bibliometric analyses were performed and presented, including novel coding of methodologies and industrial applications. Additionally, text mining analysis of the meta-data of contributions was conducted for the purpose of topic generation and retrieval of comparative insights. Results provide insights into the mapping of baseline technologies, regulatory environment, and practical factors outlined by previous contributions that influence the applications of blockchains for this cause. Future research areas include blockchains paired with other future-proof technologies, such as digital accounting tools (e.g. XBRL) or hardware IoT technologies in smart factories, to aid in the development of new pipelines of measurable and traceable sustainability information.

Model-driven architecture: generating models from Symfony framework

The web application development industry is constantly growing due to the extensive use of web applications in different devices, most of them run on Android, iOS, and Windows Phone operating systems. However, the development of applications designed for platforms requires more concerns such as code efficiency, interaction with devices, and speed of market penetration. The model-driven approach (MDA) combined with unified modeling language (UML) could provide abstraction and automation for software developers. This paper presents an MDA approach for the development of web applications based on the Symfony framework, UML modeling, model transformation, and then automatic code generation in order to facilitate and accelerate the development of web applications. The first step of this work is to establish the metamodel of Symfony framework and the metamodel of UML class diagram. In the second step, the various transformation rules between the source and target metamodels are first defined. Atlas transformation language (ATL) implements these rules. The result of this transformation is a platform-specific model (PSM) represented by Ecore language. The generated PSM model represents the input model of model-to-code (M2C) transformation for generating the code of web applications. To validate this work, we have implemented a case study.

Evaluating access to brentuximab in elderly patients with Hodgkin lymphoma.

e18663 Background: Despite the high survival associated with Hodgkin lymphoma (HL), established disparities exist both in survival for Black and Hispanic patients and their access to consolidative treatments like radiotherapy as demonstrated using large, population-based databases. Elderly patients with HL face inferior survival compared to younger patients. Brentuximab is an approved second line therapy for those patients with refractory/relapsed HL. We examined whether there were inequities in receipt of treatment among those diagnosed with HL in a contemporary cohort receiving frontline doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD), allowing for evaluation of targeted therapy. Methods: Data from Surveillance Epidemiology and End-Results (SEER) linked to Medicare claims were used to identify individuals diagnosed with HL from 2008 to 2017 who received frontline treatment with ABVD using applicable Healthcare Common Procedure Coding System codes. We examined differences in associations with receipt of brentuximab following ABVD within two years of diagnosis. Descriptive statistics were used to characterize the sample. We ran univariable and multivariable logistic regression models (producing adjusted odds ratios, aOR and 95% confidence intervals, CI) predicting treatment with brentuximab. Multivariable models were adjusted for age at diagnosis, sex, race/ethnicity, stage, insurance at diagnosis, and geographic location. Results: A total of 2,651 people diagnosed with HL were identified, 2,007 (76%) of which survived two years and 1,475 (56%) were still alive at last follow-up in 2019. Mean age at diagnosis was 69 years (SD: 12.4), most were men (N = 1,457, 55%), non-Hispanic White (N = 2,050, 77%), Hispanic (N = 291, 11%), or non-Hispanic Black (N = 220, 8%), diagnosed with stage I or II disease (N = 1,591, 60%), and received radiotherapy (N = 663, 23%) or brentuximab (N = 181, 7%) within two years of diagnosis. On univariable analysis, race and ethnicity did not have a statistically significant association with receipt of brentuximab as adjuvant treatment within two years of diagnosis. On multivariable analysis, individuals without insurance at diagnosis (aOR 1.54; 95% CI 1.02, 2.30) or those diagnosed with stage III or IV disease (aOR 2.04; 95% CI 1.04, 2.98) were more likely to receive brentuximab as adjuvant treatment within two years of diagnosis, after adjusting for the variables described above. Conclusions: Although we cannot definitively say that receipt of brentuximab within two years of diagnosis following ABVD is due to relapse, we posit that this can be used as a proxy for relapse. Our analysis did not demonstrate that race and ethnicity rose to traditional levels of statistical significance regarding associations with decreased odds of receiving brentuximab. In multivariable analysis, patients without insurance or diagnosed with stage III or IV disease were more likely to receive brentuximab.

Structural material nuclear data basic research

The nuclear data evaluation for deuteron-induced reactions andα-particle emission by neutron interactions is addressed within “Nuclear data for fusion technology, from basic research to full-scale applications.” The status and open questions related to these subjects in the area of nuclear data for fusion technology, specifically for the nuclear design of the ITER fusion device, the European DEMO fusion reactor, and the IFMIF-DONES Irradiation Facility, are briefly reviewed. A firm demand for accurate cross-sections of reactions induced by neutrons and deuterons exists, in this respect, within a more enlarged energy range up to 50 MeV than for fission applications. The current requirements are closely met by the TENDL Evaluated Nuclear Data Library, settled using the TALYS nuclear model code, which is one of the most widely used codes in basic research and applications including nuclear fusion technology. However, further improvement of this data library has recently been suggested, while, with respect to fission applications, not only the aforementioned energy range but also the diversity of nuclear data for fusion technologies is plainly stretched. Consequently, the progress of nuclear data activities conducted more recently on deuteron-induced reactions andα-emission by neutron interactions, throughout the European Fusion Program and subsequent to previous achievements within F4E and EUROfusion programs, is wholly summarized.

Mining Server HTTP Endpoints from Commented-Out Client-Side Code of Web Applications

In this paper we consider the problem of detecting information about HTTP endpoints on the server by extracting requests from the commented-out client code of web applications. The algorithm that extracts commented-out requests is proposed and implemented. The developed module was integrated into a static analyzer. An experiment was conducted on more than a million web pages belonging to more than 50 thousand web applications from the Alexa Top 1 million list. Requests unique to the commented code were selected for each page. Then a check was made for the existence of an associated endpoint on the server for each of them. According to the results of the experiment, it was found that commented-out requests actually occur in real web applications, they were detected in ~2.78 % of all explored sites. In addition, ~40 % of them were marked as "live", that is having an endpoint on the server. Also, a cursory analysis has shown that such endpoints often turn out to be vulnerable. The module can be used as part of a web security scanner to obtain more complete information about the server side of a web application using the black box method.

Studying the characteristics of SQL-related development tasks: An empirical study

A key function of a software system is its ability to facilitate the manipulation of data, which is often implemented using a flavour of the Structured Query Language (SQL). To develop the data operations of software (i.e, creating, retrieving, updating, and deleting data), developers are required to excel in writing and combining both SQL and application code. The problem is that writing SQL code in itself is already challenging (e.g., SQL anti-patterns are commonplace) and combining SQL with application code (i.e., for SQL development tasks) is even more demanding. Meanwhile, we have little empirical understanding regarding the characteristics of SQL development tasks. Do SQL development tasks typically need more code changes? Do they typically have a longer time-to-completion? Answers to such questions would prepare the community for the potential challenges associated with such tasks. Our results obtained from 20 Apache projects reveal that SQL development tasks have a significantly longer time-to-completion than SQL-unrelated tasks and require significantly more code changes. Through our qualitative analyses, we observe that SQL development tasks require more spread out changes, effort in reviews and documentation. Our results also corroborate previous research highlighting the prevalence of SQL anti-patterns. The software engineering community should make provision for the peculiarities of SQL coding, in the delivery of safe and secure interactive software.

Seismic performance assessment and retrofitting proposal for a historic masonry school building (Bursa, Türkiye)

The current paper presents all stages of a masonry building restoration including seismic performance assessment of the restored building, and a seismic retrofitting proposal accordingly. All these practices were carried out on a historical school building with timber slabs constructed in 1912. The study was composed of six stages: i. Historical research to identify all previous interventions in the building, ii. On-site examinations to determine the geometrical and structural properties of the building, iii. Laboratory tests to identify original material properties and determine repair materials, iv. Restoration decision and implementation of the restoration, v. Numerical analyses to assess the seismic performance of the restored building, and vi. Retrofitting proposal. The primary aim of this study is to present a comprehensive guide for seismic performance assessment and retrofitting approaches for similar buildings. The story shear forces and inter-story drifts of the examined building were obtained by linear and nonlinear analyses and compared with the limit values given in the applicable seismic code; accordingly, the seismic performance of the building was assessed. On the other hand, vertical and lateral bending collapse mechanisms were determined by local analyses. Based on the obtained findings, the building was found to have sufficient displacement capacity; however, failed in shear. Additionally, we believe that the presented restoration practices and seismic performance assessment aiming the structural integrity of the historic building will contribute to the literature.

Fast correlation function calculator

Context. A novel high-performance exact pair-counting toolkit called fast correlation function calculator (FCFC) is presented. Aims. With the rapid growth of modern cosmological datasets, the evaluation of correlation functions with observational and simulation catalogues has become a challenge. High-efficiency pair-counting codes are thus in great demand. Methods. We introduce different data structures and algorithms that can be used for pair-counting problems, and perform comprehensive benchmarks to identify the most efficient algorithms for real-world cosmological applications. We then describe the three levels of parallelisms used by FCFC, SIMD, OpenMP, and MPI, and run extensive tests to investigate the scalabilities. Finally, we compare the efficiency of FCFC with alternative pair-counting codes. Results. The data structures and histogram update algorithms implemented in FCFC are shown to outperform alternative methods. FCFC does not benefit greatly from SIMD because the bottleneck of our histogram update algorithm is mainly cache latency. Nevertheless, the efficiency of FCFC scales well with the numbers of OpenMP threads and MPI processes, even though speedups may be degraded with over a few thousand threads in total. FCFC is found to be faster than most (if not all) other public pair-counting codes for modern cosmological pair-counting applications.

We systematically compare national complication rates following an array of urologic surgeries by numerous providers, which can serve as an important benchmarking tool in the pursuit of quality care. METHODS: We performed a retrospective cohort study using the TriNetX research network from 2006-2022, which includes claims data for 110 million patients. Procedure type, age at index procedure, sex, race, and complications were queried using applicable CPT and ICD10 codes. Rates of all-cause (Clavien I-V), life-threatening (Clavien IV), and mortality (Clavien V) complications were evaluated using 30-day, 90-day, and 1-year timepoints from the index operation. Clavien IV complications included: sepsis, acute renal failure requiring dialysis, PE, reintubation, myocardial infarction, cardiac arrest, and re-operation. RESULTS: A total of 484,099 urologic procedures were included. Age, sex, race, and 30-day, 90-day, and 1-year complication rates stratified by procedure are listed in Table 1. All-cause complication rates ranged from 2-37%, 10-48%, and 17-60% for 30-day, 90-day, and 1-year time points, respectively. Rates of Clavien IV complications were less than or equal to 10% at all timepoints for most procedures with notable exceptions being total nephrectomy (14-23%), cystectomy (22-36%), and RPLND (14-22%). The 1-year mortality rate for most procedures was low. Exceptions include cystectomy (12%), TURBT (8%), RPLND (6%), and total nephrectomy (5%). Procedures with the lowest rates of 30-day, 90-day, and 1-year complications included those within reconstructive urology including AUS placement, sling procedures for incontinence, colporrhaphy, IPP placement and urethroplasty. 30-day, 90-day, and 1-year mortality rates following these procedures mirrored that of the general population not undergoing surgery. CONCLUSIONS: This analysis establishes benchmark complication rates up to 1-year post-op for many urologic procedures using a national database, which can aid hospital systems in identifying deficiencies in quality care.

We compare perioperative and post-surgical outcomes among patients undergoing first-time urethroplasty with use of buccal mucosa graft (BMG) who receive postoperative antibiotics versus those who do not. METHODS: A retrospective cohort study was conducted using TriNetX research network, a claims database of 110 million patient encounters between 2008-2022. Using applicable CPT, ICD10, and LOINC codes, patients>18 years old undergoing primary urethroplasty with use of BMG, who received perioperative intravenous antibiotics (IVAb), and either received an outpatient prescription for antibiotics between postoperative day 0-30 or did not were queried. Patients with positive pre-operative urine culture or urinary tract infection (UTI) within 30 days prior to urethroplasty were excluded. Surgical outcomes included 5-year revision rates and revision-free survival. Safety outcomes included new UTI within 30 days, surgical site infection (SSI) or clostridium difficile infection within 90 days of the procedure. RESULTS: We identified 645 patients (505 [78%] antibiotic cohort, 140 [22%] no-antibiotic cohort) that met inclusion criteria. There was no difference in mean age at time of urethroplasty, presence of suprapubic tube, or pre-operative rates of common medical comorbidities between cohorts (Table 1). There was no difference in type of IVAb between groups. There was no difference in 5-year rates and revision-free survival for all-cause revision (18.2% vs. 15.7%, log-rank p=0.15), endoscopic revision (10.3% vs. 12.1%, log-rank p=0.94), or surgical revision (11.1% vs. 8.6%, log-rank p=0.17) between groups. Rates of UTI within 30 days, SSI within 90 days, and clostridium difficile infection within 90 days were similar between groups. CONCLUSIONS: In this large retrospective cohort study of patients undergoing urethroplasty with use of BMG, we observed no significant benefit from the use of postoperative antibiotics on revision rates or infectious complications. Limitations of this analysis include inability to delineate between continuous versus short course prophylaxis.

AutoMPI: Automated Multiple Perspective Attack Investigation With Semantics Aware Execution Partitioning

Multiple Perspective attack Investigation ( <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">MPI</small> ) is a technique to partition application dependencies based on high-level semantics. It facilitates provenance analysis by generating succinct causal graphs. It involves an annotation process that identifies variables and data structures corresponding to the partitions and the communication channels between them. Though the amount of annotation is small, this process requires a detailed understanding of the source code. In this work, autoMPI, we extend the capability of <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">MPI</small> by automating the identifying annotation requirements. We leverage a hybrid analysis approach, performing a differential analysis based on crafted inputs. Static analysis is conducted to identify the annotation sites within the application code afterward automatically. Our evaluation shows the proposed approach can significantly facilitate the annotation process. It correctly identifies all required annotation sites within an average 16 seconds analysis time for the majority of analyzed programs with average precision and recall 72.5% and 100%, respectively.
