A Universal Graphical Solution to Calculating Seepage in Excavation of Anisotropic Soils and Non-Limited Scenarios
Authors: Navarro Carrasco Salvador , Jiménez-Valera José Antonio , Alhama Ivan 
Published: August 2023

The interaction between groundwater and civil engineering works is a key aspect in geotechnical design. In the case of excavations confined in sheet pile walls, steel sheeting, diaphragm walls, cut-off walls, or cofferdams, this design requires the estimation, among other soil mechanics properties, of the groundwater flowing into the excavation (seepage) caused by piezometry depletion. Numerical methods, graphical solutions, and analytical procedures are the methodologies traditionally used to solve this issue, solutions of which require an understanding of basic soil mechanical properties, hydraulic conditions and structure geometry. In this work, the discriminated non-dimensionalization technique is applied to obtain, for the first time, the dimensionless groups that govern the seepage, in anisotropic conditions, in large-scale scenarios where groundwater flow is not conditioned by impervious bedrock or the length of the back of the wall: π1=ab,π2=kxb2kyc2 and, π3=T/b. Numerical simulations are carried out to check the validity of dimensionless groups and to develop three sets of type curves that relate to these groups. Once the physical and geometrical data are known, the seepage (Q), the characteristic depth (T*) and the characteristic horizontal extension (L*) can be directly and easily calculated from these abacuses. The influence of anisotropy on the characteristic lengths is also addressed.

This study focuses on the development of a piezoelectric device capable of generating feedback vibrations to the user who manipulates it. The objective here is to explore the possibility of developing a haptic system that can replace physical buttons on the tactile screen of in-car systems. The interaction between the user and the developed device allows completing the feedback loop, where the user’s action generates an input signal that is translated and outputted by the device, and then detected and interpreted by the user’s haptic sensors and brain. An FEM (finite element model) via ANSYS multiphysics software was implemented to optimize the haptic performance of the wafer structure consisting of a BaTiO3 multilayered piezocomposite coated on a PET transparent flexible substrate. Several parameters relating to the geometric and mechanical properties of the wafer, together with those of the electrodes, are demonstrated to have significant impact on the actuation ability of the haptic device. To achieve the desired vibration effect on the human skin, the haptic system must be able to drive displacement beyond the detection threshold (~2 µm) at a frequency range of 100–700 Hz. The most optimized actuation ability is obtained when the ratio of the dimension (radius and thickness) between the piezoelectric coating and the substrate layer is equal to ~0.6. Regarding the simulation results, it is revealed that the presence of the conductive electrodes provokes a decrease in the displacement by approximately 25–30%, as the wafer structure becomes stiffer. To ensure the minimum displacement generated by the haptic device above 2 µm, the piezoelectric coating is screen-printed by two stacked layers, electrically connected in parallel. This architecture is expected to boost the displacement amplitude under the same electric field (denoted E) subjected to the single-layered coating. Accordingly, multilayered design seems to be a good alternative to enhance the haptic performance while keeping moderate values of E so as to prevent any undesired electrical breakdown of the coating. Practical characterizations confirmed that E=20 V/μm is sufficient to generate feedback vibrations (under a maximum input load of 5 N) perceived by the fingertip. This result confirms the reliability of the proposed haptic device, despite discrepancies between the predicted theory and the real measurements. Lastly, a demonstrator comprising piezoelectric buttons together with electronic command and conditioning circuits are successfully developed, offering an efficient way to create multiple sensations for the user. On the basis of empirical data acquired from several trials conducted on 20 subjects, statistical analyses together with relevant numerical indicators were implemented to better assess the performance of the developed haptic device.
An Independent Cascade Model of Graph Burning
Authors: Song Jiaqi , Qi Xingqin , Cao Zhulou 
Published: August 2023

Graph burning was introduced to simulate the spreading of news/information/rumors in social networks. The symmetric undirected graph is considered here. That is, vertex u can spread the information to vertex v, and symmetrically vertex v can also spread information to vertex u. When it is modeled as a graph burning process, a vertex can be set on fire directly or burned by its neighbor. Thus, the task is to find the minimum sequence of vertices chosen as sources of fire to burn the entire graph. This problem has been proved to be NP-hard. In this paper, from a new perspective, we introduce a generalized model called the Independent Cascade Graph Burning model, where a vertex v can be burned by one of its burning neighbors u only if the influence that u gives to v is larger than a given threshold β≥0. We determine the graph burning number with this new Independent Cascade Graph Burning model for several graphs and operation graphs and also discuss its upper and lower bounds.

Palliative Care Training in Pediatric Nephrology Fellowship: A Cross-Sectional Survey
Authors: House Taylor R. , Wightman Aaron , Smith Jodi , Schwarze Margaret , Bradford Miranda C. , Rosenberg Abby R. 
Published: August 2023

Key Points

Pediatric nephrology fellows have limited primary palliative exposure and opportunities to develop and refine primary palliative care (PC) skills.While experiential practice seems to improve confidence, most fellows have low confidence to provide primary PC.Fellows indicate a need and desire for additional PC training during nephrology fellowship.

Background
Children with CKD and their families encounter significant burdens. Integrating primary palliative care (PC), holistic care provided by nephrologists focused on enhancing quality of life through symptom management, stress relief, and high-quality serious illness communication, provides an opportunity to promote flourishing. Incorporation of primary PC education in training is therefore recommended. Yet, adult nephrology fellows report inadequate preparation to deliver primary PC. Similar experience of pediatric nephrology fellows is unknown. We sought to describe pediatric nephrology fellows' experience in providing primary PC and PC exposure during training.

Methods
We administered a cross-sectional web-based survey to pediatric nephrology fellows associated with the American Society of Pediatric Nephrology listserv in May 2021. The survey was adapted from a previously validated instrument and pretested by stakeholder nephrologists and subspecialty PC physicians; queries included institutional and personal PC experience, training, and confidence in primary PC delivery. Data were summarized descriptively.

Results
Response rate was 32% (32/101). Respondents were 81% female and 50% White; 87% practiced in an urban setting. Only one fellow (3%) completed a PC rotation during fellowship, and 15 respondents (48%) completed a rotation in medical school or residency. Fellows reported substantially more practice conducting kidney biopsies than family meetings; 68% of fellows had performed >10 kidney biopsies, and 3% of fellows had led >10 family meetings. Confidence in navigating challenging communication, addressing psychological distress, or managing physical symptoms associated with CKD was generally low. Fellows with greater exposure to family meetings reported more confidence navigating challenging communication. Fellows endorsed a need for additional training; 97% indicated that training should happen during fellowship.

Conclusions
Few pediatric nephrology fellows receive PC education or exposure during training, resulting in low rates of knowledge and confidence in primary PC delivery. Fellows indicate a need and desire for improved PC training.

A água é imprescindível à biodiversidade sendo um recurso natural de grande de relevância em regiões semiáridas como o Nordeste do Brasil. Com isso, é de suma importância o conhecimento da fauna de insetos aquáticos desses ambientes, pois eles podem ser importantes bioindicadores da qualidade da água e do ambiente ao seu entorno. Baseado nisso, o objetivo desse trabalho foi realizar uma análise faunística a partir dos hexápodes presentes em nove nascentes na Chapada do Araripe. Água, restos de vegetação como folhas e pequenos galhos, cascalhos e detritos, foram coletados do interior de cada nascente. Todo material coletado foi lavado em uma peneira com malha de 0,25mm e acondicionado em um recipiente de 80 mL com álcool a 70% e os invertebrados foram extraídos do substrato por meio do método Kero-float (flotação de querosene). A fauna encontrada foi caracterizada em nível taxonômico de famílias, calculando-se os índices de abundância, abundância relativa, frequência e riqueza. A ordem Diptera, foi a mais abundante em todas as nascentes com 2.677 indivíduos, sendo que desse total 2.497 foram representadas principalmente pela família Chironomidae. As nascentes Valentim de Cima, Saquinho I e Saco possuíram as maiores abundâncias, com 737, 666 e 620 chironomídeos, respectivamente. As famílias menos abundantes com apenas um indivíduo foram: Empididae, Gyrinidae, Haliplidae, Hebridae e Naucoridae. A família Chironomidae foi a mais frequente em todas as nascentes, seguido de Baetidae, Ceratopogonidae, Perlidae e Veliidae. As menos frequentes foram: Carabidae, Curculionidae, Dryopidae, Dytiscidae, Elmidae, Empididae, Gerridae, Glossomatidae, Gyrinidae, Haliplidae, Hebridae, Helicopsychidae, Naucoridae, Simulidae e Tipulidae. Com esse estudo, demonstramos que há uma diversidade de famílias de hexápodes nos mananciais avaliados, sendo que esses organismos podem ser utilizados em futuros estudos sobre a qualidade da água dessas nascentes.
