Photographer Gaspard Duval has a growing archive of the historic Paris Catacombs, a network of tunnels and burial grounds underneath the city of Paris. He navigates the underground labyrinth to highlight his favorite spots, from the official tour area to secret chambers that are forbidden to the public.

Nervous Operator is no stranger to the underground electronic music scene, having produced a string of excellent albums ranging from "Kola Dubs" in 2016 (under his Usd. alias) to most recently "Chronostasis" which came out in 2021 on Dreamtone. "Labyrinth Yrs" was recorded almost exactly five years ago at the legendary Portland, OR venue S1, a DIY club, art space and synth library where Nervous Operator held residency. It is perfectly fitting that this recording found its way to a Portland label, and the themes of ecological collapse and nuclear meltdown which permeate "Labyrinth Yrs" sound more vital than ever. $(".tralbum-about").last().bcTruncate(TruncateProfile.get("tralbum_about"), "more", "less"); credits released March 21, 2022 All music and mastering by Nervous Operator.Thank you to Felisha Ledesma and everyone at the S1 Synth Library in Portland, Oregon. $(".tralbum-credits").last().bcTruncate(TruncateProfile.get("tralbum_long"), "more", "less"); license all rights reserved tags Tags ambient club electronic ambient dub electro electronica experimental harsh noise techno Portland Shopping cart total USD Check out about Pearsoll Peak Portland, Oregon
Abstract:This paper presents a path planner solution that makes it possible to autonomously explore underground mines with aerial robots (typically multicopters). In these environments the operations may be limited by many factors like the lack of external navigation signals, the narrow passages and the absence of radio communications. The designed path planner is defined as a simple and highly computationally efficient algorithm that, only relying on a laser imaging detection and ranging (LIDAR) sensor with Simultaneous localization and mapping (SLAM) capability, permits the exploration of a set of single-level mining tunnels. It performs dynamic planning based on exploration vectors, a novel variant of the open sector method with reinforced filtering. The algorithm incorporates global awareness and obstacle avoidance modules. The first one prevents the possibility of getting trapped in a loop, whereas the second one facilitates the navigation along narrow tunnels. The performance of the proposed solution has been tested in different study cases with a Hardware-in-the-loop (HIL) simulator developed for this purpose. In all situations the path planner logic performed as expected and the used routing was optimal. Furthermore, the path efficiency, measured in terms of traveled distance and used time, was high when compared with an ideal reference case. The result is a very fast, real-time, and static memory capable algorithm, which implemented on the proposed architecture presents a feasible solution for the autonomous exploration of underground mines.Keywords: path planner; autonomous exploration; underground mines; aerial robot; LIDAR-based navigator; obstacle avoidance
In the acute phase, serous labyrinthitis may not be easily distinguishable from suppurative labyrinthitis. However, patients with serous labyrinthitis often can retain some audiovestibular function. The signs and symptoms are less dramatic than those of purulent labyrinthitis, and the pathologic consequences in the inner ear are less destructive. Every patient with serous labyrinthitis should be observed closely for development of suppurative labyrinthitis, which presents as abrupt worsening of the vestibular symptoms and sudden loss of all hearing.4 Ludman has observed that the distinction between serous and suppurative labyrinthitis is one made in retrospect after cochlear and vestibular function has returned.5 In the present case, the diagnosis of serous labyrinthitis was established retrospectively.
Until recently, the diagnosis of tympanogenic labyrinthitis was made on clinical grounds. The presence of labyrinthitis can be speculated only if bone conduction loss co-exists with otitis media. In this case, the toxins were assumed to have penetrated the round window to affect the basal turn of the cochlea; hence the resulting hearing loss was localized at the high frequencies. MRI proves to be beneficial to confirm the presence of labyrinthine inflammation by showing enhancement of the membranous labyrinth as seen on gadolinium-contrasted, T1-weighted sequences. This enhancement is typically faint and is clearly different from the intense and localized contrast enhancement that occurs in individuals with intra-labyrinthine Schwannoma.6 The enhancing labyrinth occurs most commonly in the subacute stage. The enhancement is believed to occur due to accumulation of gadolinium within inflamed labyrinthine membranes resulting from breakdown of labyrinthine vasculature.7 Aside from the characteristic, faint, diffuse nature of the contrast enhancement, segmental involvement of the labyrinth is not uncommon. Hearing loss is also a sign a cochlear involvement, and high frequency loss is closely associated with the disease extent to the basal turn of cochlea.
There are several different types of caves, the most common being solution caves. These caves are formed by the dissolving of the rock along and adjacent to joints (fractures), faults, and layers in the rock. The processes involved are both chemical corrosion and physical erosion. Solution caves are most often found in rock types such as limestone, marble, dolomite (both, close relatives of limestone), gypsum and halite, and are associated with karst landscapes.The reason these rocks dissolve is because rainwater is acidic and when it mixes with the soil it becomes undersaturated. Even though the acid is weak, it is strong enough to dissolve the limestone over extended periods of time. As we know from wells, there is a lot of water underground, and there are several ways that acids can form in that water. While weak acids are by far the most common, but there are exceptions to that rule. Limestone caves are found in dozens of National Park Units including Oregon Caves National Monument and Preserve (Oregon), Big Bend National Park (Texas), and the Chesapeake and Ohio Canal National Historic Park (Washington DC and Maryland).Gypsum and halite dissolve much more easily than limestone. They are usually found in deserts or drier environments because wet climates cause the rock to erode away quickly. Small caves in these rock types can be found in some of our desert national parks such as Death Valley National Park (California and Nevads) and Mojave National Park and Preserve (California). Caves in dolomite often appear very similar to limestone caves and limestone and dolomite are often found near each other or are even layered together like cake and icing. Caves in dolomite are common at Ozark National Scenic Riverways (Missouri) in the Ozarks. Marble is the metamorphosed version of limestone. Metamorphosed rock is rock that has undergone additional heat and pressure deep underground to change it into a different type of rock, which in this case turns limestone into marble. Chemically, marble is essentially the same as limestone and can be dissolved in the same way. Marble caves often have beautiful bands and patterns in the cave walls. Marble caves are found in Sequoia & Kings Canyon National Parks (California) and Yosemite National Park (California).
