Retroperitoneal homunculus lesion in a newborn male

Fetiform teratoma is a rare form of teratoma that resembles a malformed fetus due to highly organized differentiation. Most commonly seen arising from ovaries; however, we present a case of fetiform teratoma in the retroperitoneum in a male fetus. It is a unique case, as age, gender, and location point toward fetus-in-fetu where malignant transformation is highly unlikely. Distinction from fetus-in-fetu is necessitated due to malignant transformation in case of the presence of immature elements within.

Accurate and non-invasive localization of multi-focal ground-glass opacities via electromagnetic navigation bronchoscopy assisting video-assisted thoracoscopic surgery: a single-center study.

Accurate localization of multi-focal ground-glass opacities (GGOs) is crucial for successful video-assisted thoracoscopic surgery (VATS). Electromagnetic navigation bronchoscopy (ENB) provides a minimally invasive and dependable approach for precise localization. This study assessed the accuracy and safety of ENB-guided localization in cases involving multi-focal GGOs. This retrospective study presents a single-center investigation into ENB-guided localization, utilizing methylene blue, for multi-focal GGOs assisting VATS. Clinical, surgical, and pathological data were collected from patients who underwent ENB-guided localization between 23 December 2019 and 31 August 2022. The study examined 57 patients with multi-focal GGOs who underwent ENB-guided localization and VATS. A total of 150 GGOs were treated, with ENB-guided localization taking a median time of 65min. Following localization, all patients proceeded to VATS, with a median duration of 170min. The median lesion size measured 7.8mm, with a 5-mm distance between GGO and pleura or fissure. When the distance between GGO and pleura/fissure exceeded 1cm, an additional location point was introduced below the pleura or fissure based on GGO location. No complications related to localization were observed. The overall malignancy rate stood at 66%. Location precision was confirmed by measuring the marker-to-GGO lesion distance, resulting in a 94% (141/150) accuracy rate for GGO localization. ENB-guided methylene blue injection is a safe and precise method to treat multi-focal GGOs, potentially minimizing operation time and simplifying lesion detection.

Innovative shortcuts and initiatives in primary health care for rural/remote localities: a scoping review on how to overcome the COVID-19 pandemic.

The COVID-19 pandemic has emerged as one of the greatest challenges to societies, world health systems and science in the past century, making it imperative to restructure care networks. Therefore, it is essential to discuss the role and initiatives of primary health care (PHC) to deal with it. However, regarding the response to the pandemic, including the current global effort against COVID-19, the nuances of the rural/remote PHC context in the pandemic is barely visible. Rural and remote communities have differentiated health risks, such as socioeconomic disadvantages, difficulties in mobility and access to health services, in addition to linguistic and cultural barriers. This scoping review aimed to analyze the set of individual and collective initiatives and innovations developed to face the COVID-19 pandemic, within the PHC scope, in rural and remote areas. A scoping review methodology was applied to peer-reviewed articles. Eight databases were searched to identify scientific articles published in English, Spanish and Portuguese, initially from January 2020 to July 2021, complemented by a rapid review of articles published from January 2022 to April 2023. The main focus sought in the literature was the set of initiatives and innovations carried out within the PHC scope in rural and remote locations during the pandemic, as well as the comparison with pre-pandemic situations and between different countries. The bibliographic information of each search result was imported into Rayyan (Intelligent Systematic Review), followed by the screening and eligibility stages, performed independently by two reviewers, with a third reviewer being accessed in case of conflicts. This review included 54 studies, with publications mostly from Australia, Canada, the US and India. The main PHC initiatives were related to access; to the roles of community health workers and health surveillance; and to the importance of placing, retaining and valuing human resources in health. Cultural, equity and vulnerability issues occupy a major place among the initiatives. Regarding the innovations, telehealth and customized communication are highlighted. From an organizational point of view, rural and remote locations showed enormous flexibility to deal with the pandemic and to improve intersectoral activities at the local level. The description of rurality and remoteness is practically coincident with that of the specific populations, present in geographic areas of difficult sociospatial and cultural access. Rarely, there is an index to measure rurality, or its description deals with the need to overcome distances and obstacles. The findings highlight and summarize knowledge about initiatives and innovations developed to face the COVID-19 pandemic, within the PHC scope in rural and remote areas in the world. This review has identified collective, clinical, intersectoral and, mainly, organizational health initiatives. An articulation between different government levels would be paramount in evaluating the implementation of policies and protocols in rural and remote locations for future sanitary crises. Innovations and lessons learned are equally relevant in strengthening health services and systems. This issue calls for considerable further exploration by new reviews and empirical research that seek evidence to assess the sustainability and effectiveness of the implemented measures to face post-pandemic difficulties and other adversities.

Evaluating driving behavior patterns during wildfire evacuations in wildland-urban interface zones using connected vehicles data

Wildfire risk is increasing all over the world, particularly in the western United States and the communities in wildland-urban interface (WUI) areas are at the greatest risk of fire. Understanding the driving behavior of individuals to evacuate fire-affected WUI areas is important as the evacuees may encounter low visibility and difficult driving conditions due to burning material and steep topography. This study investigates the driving behavior patterns of individuals during historical wildfire events in rural and urban areas with mandatory evacuation orders using a connected vehicle dataset. This dataset provides the geolocation and timestamp of vehicles’ hard-braking (HB) and hard-acceleration (HA) events. The comparative analysis of the data demonstrated that the reported HA & HB event patterns were consistent in representing the varying driving behavior in response to the changing driving conditions and the depiction of the temporal and spatial impact of the fire in all studied areas. Moreover, the HB event dataset located critical traffic congestion points and the HA event dataset revealed the hurried response of evacuees on the exiting routes as a result of short-notice evacuation. In addition, significant differences in driving behavior patterns were noticed between rural and urban areas.

Vision and Tactile Robotic System to Grasp Litter in Outdoor Environments

The accumulation of litter is increasing in many places and is consequently becoming a problem that must be dealt with. In this paper, we present a manipulator robotic system to collect litter in outdoor environments. This system has three functionalities. Firstly, it uses colour images to detect and recognise litter comprising different materials. Secondly, depth data are combined with pixels of waste objects to compute a 3D location and segment three-dimensional point clouds of the litter items in the scene. The grasp in 3 Degrees of Freedom (DoFs) is then estimated for a robot arm with a gripper for the segmented cloud of each instance of waste. Finally, two tactile-based algorithms are implemented and then employed in order to provide the gripper with a sense of touch. This work uses two low-cost visual-based tactile sensors at the fingertips. One of them addresses the detection of contact (which is obtained from tactile images) between the gripper and solid waste, while another has been designed to detect slippage in order to prevent the objects grasped from falling. Our proposal was successfully tested by carrying out extensive experimentation with different objects varying in size, texture, geometry and materials in different outdoor environments (a tiled pavement, a surface of stone/soil, and grass). Our system achieved an average score of 94% for the detection and Collection Success Rate (CSR) as regards its overall performance, and of 80% for the collection of items of litter at the first attempt.

Kajian Sifat Fisik Tanah Ustifluvents Sekotong Terkait Kandungan Merkuri (Hg) Dalam Tanah

People's gold mining in Sekotong, also known as Unlicensed Gold Mining (PETI), causes environmental pollution problems because located at the surrounding community processes gold using the amlagamation technique with the help of mercury (Hg) in binding gold. Mercury waste discharged directly into the environment could have adversely affects public health and degrades soil and water quality. The presence of mercury in the soil is strongly influenced by soil characteristics, one of which is soil physical properties. The purpose of this study was to determine the relationship between the physical characteristic ustifluvents Entisol soil of Sekotong soil and mercury content at 0-20 cm soil depth. This research was conducted using descriptive method with survey technique. Soil sampling was conducted at 3 location points near the logs and tailling at a depth of 0 - 10 cm and 10-20 cm, each location point was replicated 3 times. The selection of soil sample points was based on contour differences that affect the proportion of mercury content at each soil depth. The results showed that the highest mercury content was at point 3 with an average value of 0.3089 ppm and there was a strong to very strong relationship between soil physical properties and Hg content.

Effects of Anthropogenic and Climate-Induced Habitat Changes on Adult Female Mule Deer Survival

Increased wildfire size and frequency, invasion of non-native annual grasses, extensive fire suppression, climate change, and widespread juniper expansion have led to dramatic changes in sagebrush ecosystems, which provide habitat for a suite of wildlife species, including mule deer (Odocoileus hemionus). These landscape-level disturbances can cause habitat loss and degradation, which influence the quantity and quality of available forage and can negatively influence adult female mule deer survival. We used Program MARK to estimate survival rates using a known-fate model. Our dataset included 111 radio-collared female mule deer to estimate monthly survival rates and to investigate factors that may affect these rates, including movement behavior (migratory or resident) and habitat characteristics (wildfire and juniper canopy cover) in mule deer habitats supporting sagebrush potential vegetation types (PVTs). The dataset included 116 421 Global Positioning System (GPS) location points from 2015 to 2017 in the John Day Basin, Oregon, United States. Survival averaged 0.78 (95% confidence interval = 0.61–0.82) across the study period but was 0.69 (95% confidence interval = 0.59–0.77) in 2015. Our results indicated survival was positively influenced by the presence of small amounts of recent fire (< 15% of total winter range burned; 1−20 yr postfire) within an individual's winter range. Annual survival (0.78) was low compared with survival rates for adult female mule deer in other parts of their geographic range. These findings demonstrate how postfire vegetation response can have a positive effect on mule deer survival, regardless of their migration strategy. Our findings also indicate how climate change poses a growing threat to mule deer populations as prolonged periods of drought increase the spread of fatal diseases.

User Re-Identification via Confusion of the Contrastive Distillation Network and Attention Mechanism.

With the rise of social networks, more and more users share their location on social networks. This gives us a new perspective on the study of user movement patterns. In this paper, we solve the trajectory re-identification task by identifying human movement patterns and then linking unknown trajectories to the user who generated them. Existing solutions generally focus on the location point and the location point information, or a single trajectory, and few studies pay attention to the information between the trajectory and the trajectory. For this reason, in this paper, we propose a new model based on a contrastive distillation network, which uses a contrastive distillation model and attention mechanisms to capture latent semantic information for trajectory sequences and focuses on common key information between pairs of trajectories. Combined with the trajectory library composed of historical trajectories, it not only reduces the number of candidate trajectories but also improves the accuracy of trajectory re-identification. Our extensive experiments on three real-world location-based social network (LBSN) datasets show that our method outperforms existing methods.

Potential evaluation of energy flexibility and energy-saving of PCM-integrated office building walls

Building energy flexibility is important for reducing peak-to-valley differences in air-conditioner loads. Integrating phase change material into office building envelopes and precooling can effectively reduce peak load, but precooling may increase total energy consumption. Therefore, it is imperative to investigate its energy flexibility and energy consumption features. In present work, a heat transfer model of phase change material (PCM)-integrated office building walls was established firstly and verified by experiments. Then, the energy flexibility and energy-saving potential of the PCM-integrated wall under different precooling strategies were studied, and the effects of various PCM parameters on energy flexibility and energy-saving potential were evaluated. Finally, the influence of different peak-to-valley electricity tariff differences on electricity costs was analyzed. The results show that the optimized precooling strategy and peak-to-valley electricity tariff difference make the energy flexibility index of the PCM-integrated wall up to 69.7% at a total load reduction of 1.3% and save the electricity cost by 51%. The PCM location and melting point have the most significant effect on the energy flexibility and energy-saving potential of the PCM-integrated wall under precooling operating conditions. This study guides the selection of energy flexibility and energy-saving precooling strategy and PCM parameters for PCM-integrated office building walls and the formulation of time-of-use tariff policies.

Privacy Protection Scheme for the Internet of Vehicles Based on Collaborative Services

With the development of new generation mobile communication technology, the Internet of Vehicles is playing an increasingly important role in people’s lives. However, the sensitive information contained in its “data fingerprinting" raises many privacy and security concerns. To better protect the location privacy of users on the Internet of Vehicles, this paper proposes a collaborative service-based privacy protection scheme for the Internet of Vehicles. In this scheme, each requesting user first initiates a location service query by generating a pairing index of the location points set. Then a customized pairing result threshold is used to determine the collaborating users that can participate in the service response. And in the process, the location privacy of users is secured by location point generalization and encryption. In addition, redundant location service recommendations are eliminated by the proposed repeatability tests. Security analysis and experiments show that this scheme has good performance and anti-privacy leakages, forgery attacks, collusion attacks, etc.
