The Mechanism of Enterprise Digital Transformation on Resilience from the Perspective of Financial Sustainability
Authors: Liu Ting , Qi Juan
Published: August 2024

In the period following the global COVID-19 pandemic, financial sustainability has become critical for the survival of enterprises around the world. This paper investigates the mechanisms and implications of digital transformation on resilience from the perspective of financial sustainability, that is, financial resilience. Employing a sample of Chinese listed firms, the study documents that digital transformation was positively related to financial resilience in normal states due to improved internal corporate governance, increased analyst coverage, alleviated financial constraints, and reduced operation risk. The relationship was more significant for companies with digitally literate executives, non–state–owned companies, and high–tech companies. However, it was not significant during the period of the COVID-19 pandemic and for companies with consecutive losses and delisting warnings. These findings provide unique evidence to support the beneficial effects of digital transformation on corporate resilience and to identify strategies for strengthening financial sustainability.

Published: August 2024

The EV charging network has witnessed significant growth in the UK in the last few years due to the net zero emission target of the government by 2030. The related literature in EV charging management mainly focuses on road-traffic-parameter-based optimization and lacks detail in terms of charging statistics and cyber–security-enabled charging management frameworks. In this context, this paper proposes a novel EV Charging Management and Security (EVCMS) framework using real-time charging statistics and an Open Charge Point Protocol (OCPP). Specifically, a system model for EVCMS is presented considering charging data management and security protocols. An EVCMS framework design is detailed, focusing on charging pricing, optimization, and charging security. The experimental implementation is described in terms of client–server and charge-box-based simulation. The performance of the proposed EVCMS framework is evaluated by considering different charging scenarios and a range of charging-related metrics. An analysis of results and comparative study attest to the benefits of the proposed EVCMS framework for enabling the EV charging ecosystem.

Published: August 2024

The introduction of autonomous vehicles (AVs) has the potential to drastically change society, planning, design, and development strategies. This study uses the PRISMA protocol to carry out a systematic literature review, focusing on the backcasting method as an analytic tool. By examining. 21 studies published between 2003 and 2024, this paper highlights the phases of backcasting: visioning, policy packaging, and appraisal, and identifies critical factors necessary for the successful integration of AVs. Visioning for future driverless cities includes high-quality urban areas, active mobility, and innovative developments. Policies and Packaging suggested a focus on restricting vehicular access, transit-oriented development, and encouraging public transportation. Appraisal reveals skepticism about the positive impacts of AVs, urging policies that limit access to urban areas and promote sustainable modes of transportation. The main contribution of this study lies in its comprehensive application of backcasting to AV implementation, offering a structured approach to envisioning future urban scenarios, formulating supportive policies, and evaluating their impact. This analysis provides a solid foundation for future research, urging us to explore the intersection between AVs, citizen participation, and environmental sustainability to achieve more efficient and sustainable cities.
Optimized Feature Selection for DDoS Attack Recognition and Mitigation in SD-VANETs
Authors: Tariq Usman
Published: August 2024

Vehicular Ad-Hoc Networks (VANETs) are pivotal to the advancement of intelligent transportation systems (ITS), enhancing safety and efficiency on the road through secure communication networks. However, the integrity of these systems is severely threatened by Distributed Denial-of-Service (DDoS) attacks, which can disrupt the transmission of safety-critical messages and put lives at risk. This research paper focuses on developing robust detection methods and countermeasures to mitigate the impact of DDoS attacks in VANETs. Utilizing a combination of statistical analysis and machine learning techniques (i.e., Autoencoder with Long Short-Term Memory (LSTM), and Clustering with Classification), the study introduces innovative approaches for real-time anomaly detection and system resilience enhancement. Emulation results confirm the effectiveness of the proposed methods in identifying and countering DDoS threats, significantly improving (i.e., 94 percent anomaly detection rate) the security posture of a high mobility-aware ad hoc network. This research not only contributes to the ongoing efforts to secure VANETs against DDoS attacks but also lays the groundwork for more resilient intelligent transportation systems architectures.

Published: August 2024

Background

How GP continuity of care (GP-CoC) affects mortality in patients with type 2 diabetes (T2D) is unclear.

Aim

To examine the effect of having no continuity of care (CoC) and GP-CoC on mortality in primary health care (PHC) patients with T2D.

Design & setting

A cohort study in patients aged ≥60 years with T2D, which was conducted within the public PHC of the city of Vantaa, Finland.

Method

The inclusion period was between 2002 and 2011 and follow-up period between 2011 and 2018. Six groups were formed (no appointments, one appointment and Modified, Modified Continuity Index [MMCI] quartiles). Mortality was measured with standardised mortality ratio (SMR) and adjusted hazard ratio (aHR). GP-CoC was measured with MMCI. Comorbidity status was determined with Charlson Comorbidity Index (CCI).

Results

In total, 11 020 patients were included. Mean follow-up time was 7.3 years. SMRs for the six groups (no appointments, one appointment, MMCI quartiles) were 2.46 (95% confidence interval [CI] = 2.24 to 2.71), 3.55 (95% CI = 3.05 to 4.14), 1.15 (95% CI = 1.06 to 1.25), 0.97 (95% CI = 0.89 to 1.06), 0.92 (95% CI = 0.84 to 1.01) and 1.21 (95% CI = 1.11 to 1.31), respectively. With continuous MMCI, mortality formed a U-curve. The inflection point was at a MMCI value of 0.65 with corresponding SMR of 0.86. Age and CCI aHR for death between men and women was 1.45 (95% CI = 1.35 to 1.58).

Conclusion

Patients with no CoC had the highest mortality. In patients having care over time, the effect of GP-CoC on mortality was minor and mortality increased with high GP-CoC.

Authors: Silva Alice Martinelli Lucena Saar , Colares Carlos Augusto Chaves , Jesus Lara Souza Pêgo de , Silva Luciana Martinelli Lucena Saar , Pena Ludmila Andrade Chaves
Published: August 2024

Introdução: a tonsilectomia e adenoidectomia são cirurgias comuns na população pediátrica, sendo realizadas sob anestesia geral, por meio do uso de medicações como Sevoflurano ou Propofol, drogas essas que podem provocar o fenômeno conhecido como Delírio de Emergência (DE). Esse quadro é caracterizado por agitação, choro e  confusão e medicações como Tramadol, Midazolam e Dexmedetomidina (DEX) ajudam a reduzir os efeitos da DE, sendo a DEX uma opção promissora por seus efeitos analgésicos e sedativos. Objetivo: revisar a literatura existente sobre o uso da DEX no cenário de tonsilectomia para avaliação de sua eficácia e segurança. Metodologia: revisão integrativa com pesquisa nas bases de dados Pubmed e Lilacs, analisando artigos no período de 2016 a 2024, na qual foram encontrados 27 artigos e selecionados 16, excluindo-se aqueles duplicados e/ou incompletos. Resultados: os estudos mostraram que a infusão intra-operatória da dexmedetomidina em uma dosagem de 0,5 µg/kg foi capaz de diminuir a incidência de DE de 57% para 17%. Entretanto, outros estudos mostraram que o uso da DEX também pode apresentar efeitos hemodinâmicos, sendo relatada uma redução da frequência cardíaca e também da pressão arterial média cerca de 15 minutos após a indução anestésica. Conclusão: o uso da DEX surge como um adjuvante no cenário de anestesia geral em tonsilectomias e adenoidectomias a fim de reduzir os efeitos do DE, no entanto, devido à existência dos efeitos colaterais já conhecidos e à ausência de consenso na dosagem de administração, o seu uso deve ser feito com parcimônia para uma melhor segurança do paciente.

Published: August 2024

A otite média é uma inflamação do ouvido médio que afeta principalmente crianças menores de dois anos, embora possa ocorrer em pessoas de todas as idades. A otite média aguda (OMA) é caracterizada por dor intensa, febre e secreção purulenta, com um rápido desenvolvimento de sintomas. Em contraste, a otite média com efusão é uma forma crônica, onde há acúmulo de líquido no ouvido médio sem os sintomas agudos típicos. A anatomia da tuba auditiva, mais horizontal em crianças, facilita a entrada de patógenos e contribui para a alta incidência em jovens. A OMA é causada por uma combinação de infecções virais e bacterianas, sendo Streptococcus pneumoniae e Haemophilus influenzae os principais agentes bacterianos. Fatores como alergias e refluxo gastroesofágico também podem contribuir para a condição. A introdução da vacina pneumocócica reduziu significativamente a prevalência de OMA. O tratamento inclui antibióticos para infecções bacterianas, analgésicos para alívio da dor e descongestionantes para reduzir o edema. Procedimentos como paracentese podem ser necessários para casos graves, e o manejo de condições subjacentes é essencial para prevenir recorrências. A vacinação e a inserção de tubos de ventilação em casos persistentes são estratégias eficazes na prevenção e tratamento da OMA.

В данной статье впервые анализируются результаты интерпретации высокоточных детальных площадных магнитных съемок, выполненных в западной части Качинского антиклинория Крыма с опорой на палеомагнитные и петромагнитные исследования образцов магматических пород, отобранных из обнажений непосредственно на площади исследований. Решена задача картирования магматических образований на площади магнитных съемок. На коллекции из 140 образцов, отобранных на площади исследований, проведены в полном объеме палеомагнитные исследования, а также оценка минерального состава магнитных минералов в образцах и их концентрации методами петромагнетизма и петрографии. Проведена количественная интерпретация аномальных магнитных полей и построен ряд магнитных моделей геологических разрезов с магматическими телами с учетом суммарного вектора намагниченности интрузивов. Полученные данные позволили построить ряд магнитных 2D-моделей, что дает возможность по-новому сформировать геологические гипотезы о формировании магматического комплекса средней юры и его составе.

This paper presents the results of complex interpretation of high precision magnetic survey jointly with paleomagnetic and petromagnetic studies, which carried out in the western part of Kacha anticlinorium. Magmatic rock samples were taken from outcrops directly in the study area. Paleomagnetic studies were carried out on the collection of 140 samples taken from the study area. Magmatic formations were mapped on the magnetic survey. Mineral composition of magnetic minerals in the samples and their concentration were estimated by the methods of petromagnetism and petrography. A quantitative interpretation of anomalous magnetic fields includes a number of magnetic models of geological sections taking into account the total magnetization vector of intrusions. Which makes it possible to formulate geological hypotheses about the formation of the Middle Jurassic magmatic complex and its composition in a new way.

В сейсморазведке популярны два подхода к оцениванию формы сигнала: группа методов, основанных на статистической модели сейсмической трассы, и способы с привлечением скважинных данных. Достоинства и ограничения алгоритмов и методик известны. Здесь мы обсудим подход, который принципиально отличается от перечисленных. Идея метода восходит к работам Г. Берхаута [1] и подробно описана в книге Д. Вершуура [2]. Она основана на использовании кратных волн для выделения формы импульса.

In seismic exploration, there are two popular approaches to signal waveform estimation: methods based on a statistical model of the seismic trace and methods involving well data. The advantages and limitations of the algorithms and methods are well-known. In this article we will discuss an approach that is fundamentally different from those listed. The idea of the method goes back to the works of G. Berkhout [1] and is described in detail in the book of D. Verschuur [2]. It is based on the use of multiples for the extraction of the waveform.

Задачу коррекции фазового спектра можно отнести к нерешенным проблемам в обработке. Для минимальнофазового сигнала поиск фильтра, приводящего его к нуль-фазовому виду, - задача тривиальная, это можно сделать по корреляционной функции. Современная обработка во многом использует предположение о минимально-фазовости сейсмического импульса, однако экспериментальные данные (прежде всего ВСП) свидетельствуют, что свойства минимальной фазы чаще всего не выполняются, а если и выполняются, то весьма приближенно. К тому же трудно говорить о минимально-фазовости сигнала для записей в ограниченном диапазоне частот. Поэтому можно с уверенностью утверждать неизменную актуальность задачи. В статье представлен алгоритм фазовой деконволюции, оптимизированный для обработки 3D-данных, и продемонстрированы результаты его работы.

The problem of phase spectrum correction can be referred to unsolved problems in processing. For min-phase signal the search of filter making it to zero-phase form is a simple task, it can be done by correlation function. Modern processing uses the assumption of minimal-phase seismic waveform, while experiments show that min-phase terms are mostly not satisfied. In addition, it is difficult to talk about the min-phase signal for records in a limited frequency range. The real signal does not always satisfy the minimum-phase condition. Therefore, we can confidently state the relevance of the problem. This article presents a phase deconvolution algorithm optimized for 3D data processing and demonstrates its results.

Приуроченность динамических аномалий в волновом сейсмическом поле к русловым фациальным зонам тюменской свиты маркируется только по геометрическому признаку, так как амплитуда отражения схожа с амплитудой от других фациальных зон, что ограничивает применение стандартных подходов по автоматическому выделению объектов. При использовании актуалистического подхода к изучению геологических объектов можно говорить о подобии современных и палеообстановок, о схожести форм палеорек на картах сейсмических атрибутов и современных речных систем на космоснимках. В связи с этим для выделения русел в автоматическом режиме на сейсмических данных предлагается применять нейронные сети, а в качестве обучающих данных использовать космоснимки. Для картирования границ рек на космоснимках выполнялся топологический анализ объектов, а именно оценка персистентных диаграмм. По количеству образований новых связей на персистентной диаграмме объекты сложной геометрической формы, какими и являются русла, отделялись от остальных зон. Такой подход способствовал выделению масок русел на космоснимках, которые использовались в качестве желаемого результата на выходе нейронной сети. После обучения нейронную сеть можно применять к реальным сейсмическим данным 3D.

The confinement of dynamic anomalies in the wave field to the channel facies zones is marked only by the geometric factor, since the reflection amplitude is similar to the amplitude from other facies zones, which limits the use of standard approaches for automatic selection of objects. However, under certain conditions (similarity of modern and paleoenvironments), the shape of paleorivers on seismic data is similar to modern rivers on satellite images. Therefore, to automatically identify channels on seismic data, it may be achievable to use neural networks, and use satellite images as training data. To identify only rivers in satellite images, a topological analysis of objects was performed, namely, an assessment of persistent diagrams. According to the number of formations of new connections on the persistent diagram, objects of complex geometric shape, which are the channels, were separated from the rest of the zones. This approach contributed to the selection of channel masks on satellite images, which were used as the desired result at the output of the neural network. Once trained, the neural network can be applied to real 3D seismic data.

На подработанных горными выработками участках Верхнекамского месторождения калийных солей, расположенного на территории Пермского края, происходит переформирование плотности пород, обусловленное оседаниями земной поверхности. Повторные гравиметрические съемки позволяют выявить динамически активные зоны, где происходят процессы разуплотнения горных пород и которые представляют опасность с точки зрения сохранности рудника от затопления. В работе обобщен опыт проведения мониторинговых гравиметрических наблюдений на Верхнекамском месторождении калийных солей. Показано, что по результатам мониторинговых гравиметрических наблюдений можно прогнозировать участки опасных геологических процессов и осуществлять контроль за оседаниями земной поверхности.

On the undermined areas of the Verkhnekamskoye potash deposit, located in the Perm region, the processes of reshaping the density of rocks under the influence of the process of subsidence of the earth’s surface take place. Repeated gravimetric surveys make it possible to identify dynamically active zones where processes of rock deconsolidation occur and which pose a danger in terms of the safety of the mine from flooding. The paper summarizes the experience of carrying out monitoring gravimetric observations at the Verkhnekamskoye potash deposit. It is shown that, based on the results of monitoring gravimetric observations, it is possible to predict areas of dangerous geological processes and to control subsidence of the earth’s surface.

В статье представлены результаты работ, направленных на оценку эффективности применения технологии Structure-Oriented Depth Processing (SODP) при решении задач реконструкции волнового поля в зонах пропусков пунктов возбуждения и получения единого волнового поля на основе съемок МОГТ 3D, регистрация полевых данных по которым была проведена с параметрами методик, имеющими значительные отличия. Эффективность оценена методом сопоставления результатов, получаемых при реализации SODP и комплекса стандартных технологий, на уровне сейсмических данных до и после суммирования. В процессе работ получено практическое подтверждение эффективности применения технологии SODP для решения рассматриваемых задач, а также при выполнении проектов с использованием материалов МОГТ 3D, полученных в сложных глубинных сейсмогеологических условиях, в целом.

The effectiveness was assessed by comparing the results obtained from the implementation of SODP and a sequence of standard technologies at the level of pre-stack and post-stack seismic data. The work provided practical evidence of SODP technology effectiveness for addressing the tasks in question, as well as in terms of overall implementation of projects using CDP-3D materials collected in complex seismic and geological subsurface conditions.
