Fig. 6A
Diagnosis
OL/OH = 1.5, OsL/CaL = 2.8. Large, oval otoliths with salient and pointed posterodorsal angle. Straight, wide, well-divided sulcus; ostium large, elongate; cauda short, rectangular. Ventral area markedly large.
Etymology
‘ Gibbosus, a, um ’ = ‘hump bearing’. Alludes to the very convex inner face of the otoltihs.
Type material examined
Holotype UNITED STATES OF AMERICA • Right otolith; Maryland, Loyola Retreat House, N of Popes Creek, Woodstock Member; Fig. 6A; IRSNB P 10731.
Paratypes (2 in total) UNITED STATES OF AMERICA • 2 otoliths very badly preserved, not figured; Maryland, Loyola Retreat House, N of Popes Creek, Woodstock Member; IRSNB.
Type locality and horizon
United States of America, Loyola Retreat House, N of Popes Creek (Maryland), Woodstock Member.
Dimensions of the holotype
Length = 3.77 mm; height = 2.56 mm; thickness = 1.00 mm.
Description
The otoliths are thick and rounded, with a salient, pointed posterior end. The inner face is convex and the outer face is strongly concave. The margins are smooth. The sulcus is straight, broad, and reaching, but not opening, to the margins of both anterior and posterior rims. It is divided into an elongate ostium and a very short cauda, which is rectangular and slightly pointing downwards. The ventral area is markedly large, semicircular and forming the general shape of the otoliths.
Remarks
The otolith characters of the new species, Bauzaia gibbosa sp. nov., display a mix of those seen in the other two congeneric species, B. mucronata (Koken, 1891), and B. lamberi Dante & Frizzell, 1965, but differ from them by lacking the notable antero-dorsal bulging expansion of the dorsal rim. The appearance and shape of the otoliths of B. gibbosa are most similar to those of B. lamberi, but the former has a sulcus type resembling that of B. mucronata, especially the rectangular shape of the cauda. The new species is very rare and only known from the type locality.

Fig. 7G
Diagnosis
OL/OH = 1.5. Squarish otoliths with postero-dorsal angle. Anterior rim rounded, posterior rim largely blunt. Sulcus elongate, not divided, slightly wider posteriorly.
Etymology
‘ Pamunkeyensis, is, e ’ = ‘from the Pamunkey River’. Refers to the river area, where the specimens have been collected.
Type material examined
Holotype UNITED STATES OF AMERICA • Right otolith; Virginia, Pamunkey River, Hanovertown, Potapaco Member; Fig. 7G; IRSNB P 10744.
Type locality and horizon
United States of America, Pamunkey River, Hanovertown (Virginia), Potapaco Member.
Dimensions of the holotype
Length = 2.82 mm; height = 1.98 mm; thickness = 0.77 mm.
Description
The otolith of this species is characterized by an oval to squarish outline with a prominent postero-dorsal angle. The dorsal rim is nearly flat, and and the ventral rim is gently curved. The anterior rim is rounded, and the posterior rim is largely blunt. All margins are smooth. The otoliths are thick, with both the inner and outer faces convex (Fig. 7G 1). A straight, elongate, and undivided sulcus sits in the central zone of the otolith. The sulcus does not open to the margins. The posterior part of the sulcus is slightly wider than the anterior part and very slightly bent downward at the tip. The ventral area is of similar size as the dorsal one.
Remarks
This species is solely represented by a single specimen from the type locality. The bizarre outline and undivided sulcus are a unique character combination that does not resemble any known otolith-based species.

Fig. 8D–E
Diagnosis
OL/OH = 1.6–1.8, OsL/CaL = 2.9–4.1. Fusiform otoliths with blunt antero-dorsal bulge and pointed posterior rim.Anterior rim largely blunt. Sulcus wide, elongate, well-divided. Ostium markedly elongate; cauda oval, pointing downward.
Etymology
This species is dedicated to Gary L. Stringer (University of Louisiana at Monroe) for his major contributions to the knowledge of the fossil otoliths from the USA.
Type material examined
Holotype UNITED STATES OF AMERICA • Right otolith; Alabama, Hatchetigbee Bluff, Hatchetigbee Formation; Fig. 8E; IRSNB P 10749.
Paratypes (3 in total) UNITED STATES OF AMERICA • 3 otoliths of which one is figured: Fig. 8D; same collection data as for holotype; IRSNB P 10748.
Type locality and horizon
United States of America, Hatchetigbee Bluff (Alabama), Hatchetigbee Formation.
Dimensions of the holotype
Length = 4.36 mm; height = 2.43 mm; thickness = 1.21 mm.
Description
This species is characterized by robust and fusiform otoliths that bear a blunt antero-dorsal bulge, forming the highest and thickest part of the otoliths in the anterior portion (Fig. 8E 1). The otoliths taper in the posterior part and end with a pointed tip. The ventral rim is regularly curved. The inner face is convex; the outer face is essentially flat, becoming thinner towards the ventral and posterior rims. The sulcus occupies nearly the entire length of the inner face and is constituted by a long, horizontal ostium and a very short, downward-bent cauda. A shallow dorsal depression is observed above the central part of the crista superior. The ventral area is slightly larger than the dorsal one.
Remarks
At first glance, the otoliths of “ N. ” stringeri sp. nov. are very similar to those of N. longesulcatus sp. nov. (see above), but they can be distinguished by the short, strongly bent cauda and larger ventral area in the former species. “ Neobythites ” stringeri is only known form the type locality.

A single Ariosoma otolith was recovered from the Bashi Formation, Mississippi (Table 1). The otolith differs from the common species of Ariosoma, A. nonsector Nolf & Stringer, 2003, by having a flatter dorsal rim, but we retain our identification due to the lack of sufficient specimens.

Fig. 3C–D
The otoliths are elongate to rectangle in shape, with a cauda that is bent downward and a nearly flat dorsal rim that ends with a weak postero-dorsal angle. Albula meridiana was originally described as Eoalbula meridiana by Frizzell (1965), and later assigned to the “ genus Albulidarum ” by Nolf (1985) and remained as such in the following literature (Müller 1999). However, the species remains doubtful (Nolf 2013) and requires further study as suggested by Nolf & Dockery (1993). Frizzell’s taxonomic acts were questionable, as they were mainly based on poorly-preserved or juvenile specimens, and his otolith-based genera were forced to reveal tentative evolutionary lineages. Despite this, based on their distinct characters, the three better-preserved otoliths described in this study can be confidently assigned to this species. Albula meridiana is only known from the Bashi Formation of Mississippi.

We assign a medium-sized otolith from the Rappahannock River, Virginia, to “ M. ” papillosus based on distinct features, including an obtuse rostrum, relatively flat dorsal and ventral rims, a wide and pincenez-shaped sulcus, and an upward-oriented ostium. Although about one-third of its posterior part is not preserved, we deem these characteristics to be sufficient for identification. The species is known from Lutetian European deposits, including the English Hampshire Basin, Belgian Basin, and NW Germany (Osteroden) (Lin et al. 2017b). This specimen represents the first occurrence of “ M. ” papillosus in the Americas.

Based on the poor preservation and lack of distinct features, the ariid otoliths in the collection could not be confidently identified to the species level and are therefore assigned as Ariidae indet. The lack of common occurrence of ariid otoliths in the studied localities could indicate a low abundance of ariids.

An oblong otolith from the Rappahannock River locality in Virginia possesses an obtuse, moderately protruding rostrum and a sulcus type most similar to “ N.” constrictus from the Ypresian London Clay of southern England. The more compact outline of the otolith and flatter inner face are considered as size-related intra-specific variability.

Otoliths belonging to this species are commonly found in the Bashi and Hatchetigbee formations and share several distinctive characteristics with those of P. arcuatus from the Ypresian London Clay, as described by Stinton (1966) under the name Brotula arcuatus. The general outline of the otoliths, as well as the downward-bent cauda, suggest that this species can be assigned to the fossil genus Preophidion.

description: Lamellipalpus atripalpis sp. nov.
(Fig. 12)
Type locality: NE India, Meghalaya, SW of Cherrapunjee.
Description. 3. Habitus: Body elongate, subparallel, completely testaceous brown; the antennae and the labial and maxillary palpi dark brown. Underside completely testaceous.
Head: Testaceous brown, broad; the distance from eye to pronotum equal to 1.6 times as long as eye diameter. Interocular space large, 3 times as large as eye diameter. Anterior margin of frons almost evenly curved, distinctly concave; head strongly depressed on antero-median part. Surface shining, covered with fine and long yellow setae. Mandibles long straight, distinctly dilated medially. Last segments of the maxillary and labial palpi dark brown, slender, 4 times as long as broad, flattened. Antennae long, filiform, joints cylindrical, dark brown 1st, 3rd, 4th and 5th joints elongate, 2nd joint very small, globose, 6th–8th joints subequal, 2.3 times as long as broad, the last three joints short, almost as broad as long.
Pronotum: Testaceous, strongly transverse, trapezoidal, depressed posteriorly before posterior angles; posterior angles protruding with a sharp ridge. Entire surface shining with small punctures, each with a long and very fine seta. Scutellum somewhat elongate, triangular and testaceous.
Elytra: Testaceous, the costae not really distinct, coarsely punctured; punctures large, superficially impressed and closer together than their own diameter. Pubescence dense; setae yellow, fine and long. Elytral margins slightly bordered.
Underside: Completely testaceous.
Aedeagus: Lateral lobes broad, square-edged, rounded posteriorly and ending in a ridge dorsally. median lobe with a sharp ridge dorsally
Female: Unknown.
Measurements: TL: 6.7 mm; TL-H: 5.9 mm; HL: 1.7 mm; HW: 1.7 mm; LP: 1.8 mm.
Type material: Holotype 3 (NHMB): “NE India, Meghalaya, SW of Cherrapunjee, 25°14’N 91°40’E, 900 m, P. Pacholátko, 21–25.VI.07 ”. “ Holotype Lamellipalpus atripalpis n.sp. Brancucci & Geiser 08” [red printed label].
Etymology: The name was selected because of the unusual, completely dark palpi and antennae on a body that is completely testaceous brown.
Affinities: This species can be distinguished from all other known species by the testaceous brown and subparallel body, and by the maxillary and labial palpi as well as the antennae which are completely dark brown, but also by the absence of distinctly visible costae on the elytra. Furthermore, the 4th– 9th antennal joints are more than twice as long as broad.
Distribution: NE India (Meghalaya).

From the very short description by M. Pic, it was not possible to tell if this species belongs to Eugeusis, Lamellipalpus or Lamellipalpodes. The single male type from "Shembaganur, India " (Tamil Nadu), deposited at MHNP, was examined. According to the shape of its head and antennae, it is clearly a member of Lamellipalpodes Maulik.

Taylan) and male calling song recorded from three males in the field and laboratory (or room) conditions by authors.
Description of male calling song: In totally, three records from three males were examined. The main component of a calling song consists of a phrase, lasting 13.92–17.18 s and composed of about 42–71 syllables (Fig. 4A). The phrase begins quietly and crescendo structure and is reached the maximum intensity at the 30–40 syllables (1/2 of the phrase) (Fig. 4A). Each syllable (RPU) lasts in 210–340 ms. Oscillographic analysis shows that a syllable consists of two different parts (Figs. 4B and 4C). The syllable begins with the low-amplitude part (with unified indistinct pulses without gap) which last 92–138 ms and the second part of the syllable (duration: 105–194 ms) includes higher amplitude distinguishable 8–10 pulses.

NEXT-GENERATION VIDEO CODECS: HEVC VS AV1 FOR 8K UHD VIDEO PERFORMANCE AND COMPATIBILITY
Creators: name: Liang Wei, Cheng

Year: 2024
Subjects: 8K UHD Video, Video Coding Standards, HEVC, AV1, Video Compression Performance

description: 8K UHD video, with its remarkable resolution and quality, has found applications in diverse domains, including entertainment, education, healthcare, security, and sports. Nevertheless, the demands it imposes on data, computation, and video coding quality are substantial. Video coding, the process of compressing and decompressing video data for efficient storage and transmission, faces formidable challenges due to the massive data size, complexity, and quality requirements inherent in 8K UHD video. This paper delves into the intricacies of video coding for 8K UHD video, focusing on two prominent standards: HEVC and AV1. HEVC, an international standard introduced in 2013, has doubled video data compression efficiency compared to its predecessor. In contrast, AV1, an open-source standard developed in 2018, surpasses HEVC by achieving a 30% higher compression rate. This research aims to address the following question: How do HEVC and AV1 measure up in terms of performance, complexity, and compatibility for 8K UHD video coding? The paper's thesis contends that AV1 outperforms HEVC in terms of performance and compatibility, but HEVC remains more accessible and user-friendly for 8K UHD video coding.
