COVID-19 has transformed face-to-face software development into distributed development (e. g., remote work). While the company authors belong to studies microtask programming, an open source software (OSS) -like development, as a solution to employ distributed development, a prior study reports a challenge: online communication in microtask programming takes longer; such lengthy communication discourages developers and affects their completion of assigned tasks. OSS, however, is successfully developed using online communication, such as issues. Hence, we have a question: how does OSS address the online communication challenge? In this experience report, we answer this question based on an empirical study on OSS communication. We found that (1) OSS prefers burst communication similar to face-to-face development, and (2) attracting developers’ attention may be a possible solution. Based on the findings, we discuss the direction of future studies to achieve better online communication in microtask programming in the company. The main contributions of this report are (1) to empirically reveal the actual communication times in OSS and (2) to show how an empirical approach helps industrial collaborators.
COVID-19将面对面的软件开发转变为分布式开发(例如远程工作)。虽然该公司的作者属于研究微任务编程,一种类似开源软件(OSS)的开发,作为采用分布式开发的解决方案,但先前的一项研究报告了一个挑战:微任务编程中的在线通信需要更长的时间;这种冗长的沟通会使开发人员气馁,并影响他们完成分配的任务。然而,开源软件是通过在线交流(如问题)成功开发的。因此,我们有一个问题:OSS如何应对在线通信的挑战?在这份经验报告中,我们基于对OSS通信的实证研究来回答这个问题。我们发现(1)OSS更喜欢类似于面对面开发的突发通信,(2)吸引开发人员的注意力可能是一个可能的解决方案。在此基础上,我们讨论了未来的研究方向,以实现公司微任务编程中更好的在线交流。本报告的主要贡献是:(1)经验地揭示了OSS中的实际通信时间,(2)展示了经验方法如何帮助工业合作者。

In recent years we have understood the importance of analyzing and sequencing human genetic variation. A relevant aspect that emerged from the Covid-19 pandemic was the need to obtain results very quickly; this involved using High-Performance Computing (HPC) environments to execute the Next Generation Sequencing (NGS) pipeline. However, HPC is not always the most suitable environment for the entire execution of a pipeline, especially when it involves many heterogeneous tools. The ability to execute parts of the pipeline on different environments can lead to higher performance but also cheaper executions. This work shows the design and optimization process that led us to a state-of-the-art Variant Calling hybrid workflow based on the StreamFlow Workflow Management System (WfMS). We also compare StreamFlow with Snakemake, an established WfMS targeting HPC facilities, observing comparable performance on single environments and satisfactory improvements with a hybrid cloud-HPC configuration.
近年来,我们已经认识到分析和测序人类遗传变异的重要性。2019冠状病毒病大流行带来的一个相关方面是需要非常迅速地取得结果;这涉及到使用高性能计算(HPC)环境来执行下一代测序(NGS)管道。然而,HPC并不总是最适合整个管道执行的环境,特别是当它涉及许多异构工具时。在不同环境中执行部分管道的能力可以带来更高的性能,同时也降低了执行成本。这项工作展示了设计和优化过程,使我们能够基于StreamFlow工作流管理系统(WfMS)实现最先进的变体调用混合工作流。我们还将StreamFlow与Snakemake进行了比较,后者是一款针对HPC设施的成熟WfMS,在单一环境下观察到相当的性能,并在混合云-HPC配置下进行了令人满意的改进。

Transparency-based reconnaissance for APT attacks 基于透明度的APT攻击侦察
Pub Date : 2023-06-01 DOI: 10.1109/COMPSAC57700.2023.00255

Transparency is a fundamental administrative principle for public institutions. One of its main implementations is the publication of goods and service acquisition tenders, as prescribed by EU and national legislation. This need of transparency can however undermine the security of public institutions, which are disseminating information that could be leveraged by advanced threat actors to bring disruptive attacks. In this paper, we analyse how threat actors can extract useful information from this publicly available information, taking advantage from transparency. We introduce a new technique named transparency-based reconnaissance, which implements a passive recognition process using transparency information published under law requirements. To better highlight the value of the gathered data, we experiment its effectiveness by simulating a transparency-based reconnaissance run against an Italian public institution, obtaining complete technological and supply chain inventories. The collected inventories enabled the creation of an unsophisticated malware bypassing the defences in place, along with a weaponization and delivery strategy. Finally, we propose a list of potential countermeasure areas, both technical and organizational, to protect information while still safeguarding transparency through a graduated approach.
透明是公共机构的一项基本行政原则。其主要实施之一是根据欧盟和国家立法的规定,公布货物和服务采购招标。然而,这种对透明度的需求可能会破坏公共机构的安全,因为公共机构传播的信息可能被高级威胁行为者利用来发动破坏性攻击。在本文中,我们分析了威胁行为者如何利用透明度从这些公开可用的信息中提取有用的信息。本文介绍了一种基于透明度的侦察技术,该技术利用法律要求下公布的透明度信息实现被动识别过程。为了更好地突出所收集数据的价值,我们通过模拟针对意大利公共机构的基于透明度的侦察运行来试验其有效性,获得完整的技术和供应链清单。收集到的清单可以创建一个简单的恶意软件,绕过现有的防御,以及武器化和交付策略。最后,我们提出了一份潜在的对策领域清单,包括技术和组织方面的,以保护信息,同时通过渐进式方法维护透明度。

Efficient Diverse Redundant DNNs for Autonomous Driving 用于自动驾驶的高效多样冗余dnn
Pub Date : 2023-06-01 DOI: 10.1109/COMPSAC57700.2023.00013

Automotive applications with safety requirements must adhere to specific regulations such as ISO 26262, which imposes the use of diverse redundancy for the highest integrity levels (i.e., ASIL D). While this has been often achieved by means of Dual-Core LockStep (DCLS) for microcontrollers, it remains an open challenge how to realize diverse redundancy efficiently, i.e., without full duplication and preserving performance, for DNN-based safety-related tasks, such as object detection, needing accelerators for performance reasons.This paper proposes an architecture where the accelerator performing DNN inference is replicated, as in the case of DCLS for cores, but using a cheaper implementation for the replica. In particular, we build on the stochastic nature of DNN-based object detection to realize two redundant accelerators where the secondary accelerator uses smartly chosen lower precision arithmetic (e.g., dropping some bits of the original data) so that it provides diverse redundancy, it can keep the performance of the primary accelerator, does not require as much cost as full- precision replication, and can build on the very same data stream from memory used by the primary accelerator. With a simple heuristic, we show that such a diverse redundancy scheme is able to cope with faults restricting false positives and negatives to a few relatively small objects.
具有安全要求的汽车应用必须遵守特定的法规,如ISO 26262,该法规规定使用不同的冗余来实现最高的完整性级别(即ASIL D)。虽然这通常是通过微控制器的双核LockStep (DCLS)来实现的,但如何有效地实现不同的冗余仍然是一个开放的挑战,即没有完全的重复和保持性能,对于基于dnn的安全相关任务,如对象检测,出于性能原因需要加速器。本文提出了一种架构,其中执行DNN推理的加速器被复制,就像DCLS用于核心的情况一样,但使用更便宜的副本实现。特别是,我们基于基于dnn的对象检测的随机特性来实现两个冗余加速器,其中二级加速器使用智能选择的低精度算法(例如,删除原始数据的一些位),从而提供不同的冗余,它可以保持主加速器的性能,不需要像全精度复制那样多的成本,并且可以建立在主加速器使用的存储器中相同的数据流上。通过一个简单的启发式,我们证明了这种多样化的冗余方案能够处理将假阳性和假阴性限制在几个相对较小的对象上的故障。

The safety of autonomous vehicles relies on dependable and secure infrastructure for intelligent transportation. The doctoral research described in this paper aims to enable self-healing and survivability of the intelligent transportation systems required for autonomous vehicles (AV-ITS). The proposed approach is comprised of four major elements: qualitative and quantitative modeling of the AV-ITS, stochastic analysis to capture and quantify interdependencies, mitigation of disruptions, and validation of efficacy of the self-healing process. This paper describes the overall methodology and presents preliminary results, including an agent-based model for detection of and recovery from disruptions to the AV-ITS.

With the spread and development of 5G technology, network configurations with MEC (Multi-Access Edge Computing) servers in the vicinity of 5G base stations are becoming more common. We have been researching and developing Giocci, a resource permeating distributed processing platform that offloads computation tasks on end devices to MEC servers and cloud servers. In this paper, we propose resource allocation methods to efficiently determine the server to which tasks are allocated in a network configuration that includes MEC servers. In order to construct the proposed methods, we first model the main functions of Giocci and define the resource allocation problem for this work. There are four proposed methods according to each objective and priority; a prioritized allocation by the average number of waiting tasks, by the communication delay, by the task response time, and by the cost of using computing resources. We initially implement these methods assuming that they are task allocation functions in Giocci. Experimental evaluations demonstrate that they could achieve appropriate resource allocation results for each objective. This research contributes to the smooth allocation of computational resources in 5G networks including MEC servers.
随着5G技术的普及和发展,在5G基站附近使用MEC (Multi-Access Edge Computing)服务器的网络配置越来越普遍。我们一直在研发Giocci,这是一个资源渗透的分布式处理平台,可以将终端设备上的计算任务卸载到MEC服务器和云服务器上。在本文中,我们提出了资源分配方法,以有效地确定在包含MEC服务器的网络配置中分配任务的服务器。为了构建所提出的方法,我们首先对Giocci的主要函数进行建模,并定义了本工作的资源分配问题。根据每个目标和优先事项,有四种建议的方法;按等待任务的平均数量、通信延迟、任务响应时间和使用计算资源的成本进行优先级分配。我们最初实现这些方法时假设它们是Giocci中的任务分配函数。实验评价表明,该方法能够实现各目标的合理资源分配结果。本研究有助于包括MEC服务器在内的5G网络计算资源的顺利分配。

Quantum machines are among the most promising technologies expected to provide significant improvements in the following years. However, bridging the gap between real-world applications and their implementation on quantum hardware is still a complicated task. One of the main challenges is to represent through qubits (i.e., the basic units of quantum information) the problems of interest. According to the specific technology under-lying the quantum machine, it is necessary to implement a proper representation strategy, generally referred to as embedding. This paper introduces a neural-enhanced optimization framework to solve the constrained unit disk problem, which arises in the context of qubits positioning for neutral atoms-based quantum hardware. The proposed approach involves a modified autoencoder model, i.e., the Distances Encoder Network, and a custom loss, i.e., the Embedding Loss Function, respectively, to compute Euclidean distances and model the optimization constraints. The core idea behind this design relies on the capability of neural networks to approximate non-linear transformations to make the Distances Encoder Network learn the spatial transformation that maps initial non-feasible solutions of the constrained unit disk problem into feasible ones. The proposed approach outperforms classical solvers, given fixed comparable computation times, and paves the way to address other optimization problems through a similar strategy.
量子机器是最有前途的技术之一,有望在未来几年提供重大改进。然而,弥合现实世界的应用和它们在量子硬件上的实现之间的差距仍然是一项复杂的任务。主要的挑战之一是通过量子位(即量子信息的基本单位)来表示感兴趣的问题。根据量子机器背后的具体技术,有必要实现适当的表示策略,通常称为嵌入。本文介绍了一种神经增强优化框架来解决中性原子量子硬件中量子位定位的约束单元磁盘问题。提出的方法包括一个改进的自编码器模型,即距离编码器网络,和一个自定义损失,即嵌入损失函数,分别计算欧几里得距离和建模优化约束。该设计背后的核心思想依赖于神经网络近似非线性变换的能力,使距离编码器网络学习空间变换,将受限单元盘问题的初始非可行解映射为可行解。所提出的方法优于经典求解器,给定固定的可比计算时间,并通过类似的策略为解决其他优化问题铺平了道路。

This paper presents a systematic review of the use of multilevel models for the analysis and prediction of school dropout. Several studies were carried out in this theme, but there are still challenges to be addressed. There are many different applications of multilevel modeling for school dropouts, which makes it difficult to synthesize the main contributions and advances in the area. The lack of a holistic view makes it difficult to understand the main advances and research gaps. To shed some light on this scenario, this literature review covered the most investigated factors at the student and school levels, such as demographic, socioeconomic, family background, and student’s academic performance variables; the main educational environments in which multilevel models were used for the analysis or prediction of school dropout, such as high school/secondary education, and higher education; and the main multilevel models used in these researches, such as the multilevel logistic regression, and the multilevel linear regression. In addition, we also investigated whether the authors used multivariate exploratory techniques or other artificial intelligence techniques to support the fitting and interpretation of the modeling process.
本文系统地回顾了多层模型在分析和预测辍学中的应用。就这一主题进行了若干研究,但仍有挑战有待解决。多层模型在辍学研究中的应用有很多,这使得很难综合该领域的主要贡献和进展。缺乏整体的观点使得很难理解主要的进展和研究差距。为了阐明这一情况,本文献综述涵盖了学生和学校层面调查最多的因素,如人口统计、社会经济、家庭背景和学生学业成绩变量;多层模型用于分析或预测辍学的主要教育环境,如高中/中等教育和高等教育;研究中主要采用的多层次模型有多层次逻辑回归、多层次线性回归等。此外,我们还调查了作者是否使用了多元探索技术或其他人工智能技术来支持建模过程的拟合和解释。

INTRODUCTION: During COVID-19 pandemic, Telehealth was crucial to the delivery of healthcare services. it is expected that even after the pandemic is almost over, providers will probably start using telehealth on a regular basis as we transition to the “new normal.” Therefore, it is crucial to identify and resolve any discrepancies in telehealth’s effectiveness and accessibility. OBJECTIVES: Examine disparities in telehealth access and explain how frequently OB-GYN patients used telehealth during the first four months of the COVID-19 pandemic according to race/ethnicity and insurance status. METHOD: A cross-sectional design was used including a convenience sample of 9370 women who received telehealth or in-person care. RESULTS: 15,362 encounters were completed in total. 81.34% of appointments were held in person throughout the study’s time period, and 18.66% were managed by telehealth. The majority of the patients had private health insurance (n = 975, 52.4%) and were Caucasian (n = 1202, 63.4%). Compared to patients of other races, patients of Hispanic and Asian descent were less likely to attend their telehealth appointment (p< 0.001). Patients with private health insurance were more likely than those with public health insurance to show up for their telehealth appointments (p< 0.001).CONCLUSION: This study demonstrates that underserved populations, including individuals of color, those with public insurance, and others, must have greater access to and utilization of telehealth services.
导言:在2019冠状病毒病大流行期间,远程医疗对提供医疗保健服务至关重要。预计即使在大流行几乎结束之后,随着我们向“新常态”过渡,提供者可能会开始定期使用远程医疗。因此,确定和解决远程保健的有效性和可及性方面的任何差异至关重要。目的:检查远程医疗获取的差异,并根据种族/民族和保险状况解释在COVID-19大流行的头四个月,妇产科患者使用远程医疗的频率。方法:采用横断面设计,包括9370名接受远程医疗或现场护理的妇女。结果:共完成15362次就诊。在整个研究期间,81.34%的预约是亲自进行的,18.66%是通过远程医疗管理的。大多数患者有私人医疗保险(n = 975, 52.4%),白人(n = 1202, 63.4%)。与其他种族的患者相比,西班牙裔和亚裔患者参加远程医疗预约的可能性较小(p< 0.001)。拥有私人医疗保险的患者比拥有公共医疗保险的患者更有可能参加远程医疗预约(p< 0.001)。结论:这项研究表明,服务不足的人群,包括有色人种、有公共保险的人,以及其他人,必须有更多的机会获得和利用远程医疗服务。
