ACP-DRL: an anticancer peptides recognition method based on deep representation learning

Cancer, a significant global public health issue, resulted in about 10 million deaths in 2022. Anticancer peptides (ACPs), as a category of bioactive peptides, have emerged as a focal point in clinical cancer research due to their potential to inhibit tumor cell proliferation with minimal side effects. However, the recognition of ACPs through wet-lab experiments still faces challenges of low efficiency and high cost. Our work proposes a recognition method for ACPs named ACP-DRL based on deep representation learning, to address the challenges associated with the recognition of ACPs in wet-lab experiments. ACP-DRL marks initial exploration of integrating protein language models into ACPs recognition, employing in-domain further pre-training to enhance the development of deep representation learning. Simultaneously, it employs bidirectional long short-term memory networks to extract amino acid features from sequences. Consequently, ACP-DRL eliminates constraints on sequence length and the dependence on manual features, showcasing remarkable competitiveness in comparison with existing methods

Angled fiber-based Fabry–Perot interferometer

Herein, we propose and experimentally demonstrate a novel, to the best of our knowledge, all-fiber Fabry–Perot (FP) interferometer that is formed by a simple angled fiber that can function as a beam splitter. According to the principle of the angled fiber, we verify the influence of an oblique angle on the light propagation path and light intensity ratio. Subsequently, angled fiber-based FP interferometers are experimentally demonstrated, and the influence of the oblique angle on the visibility of interference fringes and temperature characteristics is investigated. Finally, the temperature characteristics of this proposed FP interferometer are investigated experimentally, and the temperature sensitivity is 12.62 and 10.89 pm/°C for 42° and 40° angled fiber-based fiber FP interferometers, respectively. This proposed FP interferometer is fabricated by using a simple angled fiber, which has the advantages of ease of fabrication and all-fiber characteristics and hence can meet the requirements of mass production and high stability in various practical application areas

Arbitrary spectral synthesis and waveform generation with HiBi fiber loop mirrors

An arbitrary spectral synthesis scheme with parallel-connecting high-birefringence fiber loop mirrors (HiBi-FLMs) based on Fourier synthesis theory has been proposed and demonstrated. Three typical spectra of triangle, rectangle and sawtooth shape have been synthesized by implementing only four HiBi-FLMs. The experimental results are in good agreement with theoretical simulations with a goodness of fit of 0.9565. Furthermore, higher precise optical spectrum with narrower bandwidth can be obtained by adopting longer polarization- maintaining fiber and more sections of HiBi-FLMs. Besides, a typical application of arbitrary waveform generation has been implemented. By incorporating with frequency-to- time mapping, triangle- and sawtooth-shaped electrical pulses with repetition rate of 1 GHz and pulse width of ~860 ps have been generate

WXP03266. Diagnosis. The new species is similar to Egogepa zosta by having a specialized “scent organ” in the hindwing and lacking the coecum penis. It can be separated from the latter by the complete and distinct medial fascia, the long uncus, the slender socius, and the lateral process of the gnathos. Description. Adult (Fig. 3): Wingspan 13.0 mm. Labial palpus short, length about 1.0 times diameter of compound eye; frons, antenna, and tegula yellowish; thorax pale brown. Forewing expanded distally, lacking costal fold; apex short and blunt; termen obliquely straight. Ground color of forewing whitish yellow, with scattered dark brown scales; pattern elements dark brown: basal blotch and subapical blotch indistinct; medial fascia extending from middle of costa to dorsum, broad posteriorly; cilia pale yellowish. Hindwing and cilia pale gray, with a large cluster of broad scales between anal and cubital veins (= scent organ?). Legs whitish yellow, with some brown scales. Male genitalia (Fig. 6): Tegumen broad and short, lateral sclerite large, boot-shaped. Uncus long, thick, slightly expanded from middle, pointed apically, densely covered by a group of sclerotized sockets of bristles or scales; socius slender; gnathos with strong lateral processes. Transtilla bandlike, broadened laterally. Valva broad, expanded distally; costa long, well developed; sacculus strongly sclerotized, narrow, long. Aedeagus short, narrow, weakly sclerotized, slightly narrowed beyond middle; coecum penis lacking, caulis small; no cornutus in vesica. Female: Unknown. Distribution. China (Tibet). Etymology. The specific name is derived from the Latin word crassatus (= crassus), referring to the long uncus.Published as part of Wang, Xinpu & Li, Houhun, 2006, Review of Egogepa Razowski, with description of a new species (Lepidoptera: Tortricidae), pp. 27-31 in Zootaxa 1377 on page 31, DOI: 10.5281/zenodo.17499

Synochoneura dentana Wang & Li, sp. nov.

Synochoneura dentana Wang & Li, sp. nov. (Figs. 2, 5) Type material: Holotype: ɗ, CHINA: Mt. Fanjing (27 º 55 'N, 108 º 41 'E), Guizhou Province, 1300 m, 2.viii. 2001, Houhun Li & Xinpu Wang, genital slide no. WXP03148. Diagnosis. The new species resembles S. ochriclivis (Meyrick) superficially, but differs from it in several features of the male genitalia: the valva is broad and short without a distinctly narrowed neck, and the sacculus is short and weakly sclerotized, not reaching the termination of the costa of valva. It can be distinguished from S. tapaishani (Caradja) by the distal part of valva distinctly contracted, the free termination of sacculus dentate, and the aedeagus stout. Description. Adult (Fig. 2). Wingspan 17.0 mm. Head: Labial palpus slightly longer than diameter of compound eye, outer surface yellowish brown except end of second segment and third segment white. Frons white, vertex with erect, rough white scales. Antenna pale yellowish brown, ciliate. Tegula yellowish brown. Thorax: Dorsum yellowish brown basally, with erect crest of brown scales posteriorly. Legs yellowish white, outside of foreleg, tibiae and tarsi of midleg with gray brown scales. Forewing narrow; costal margin slightly convex from base to middle, then straight; apex short and pointed; termen obliquely straight; tornus broad; upperside ground color pale yellow on upper 1 / 3, with scattered brown and white scales, brown on lower 2 / 3; basal fascia large, dark brown; costal margin yellowish brown, tornus golden; cilia yellowish brown at apex, the remainder yellow; underside pale brown. Hindwing upperside, including cilia, gray white, tinged with yellow apically; underside pale. Abdomen: Male genitalia (Fig. 5) with tegumen broad, with large intercalar sclerite between gnathos arm and tegumen. Uncus short and thin, curved, pointed apically, with a few bristles. Socius long, narrowed basally and expanded terminally. Gnathos with slender arms, terminal part broad. Valva broad basally, conspicuously narrowed distally; costa developed. Transtilla broad, narrowed at middle. Sacculus short, narrow, sclerotized, reaching beyond middle; free termination dentate. Juxta broad, rounded, expanded dorsally. Aedeagus stout, gently bent, narrowed distally, blunt apically; vesica with sclerotized fold, cornuti absent. Female unknown. Etymology. The specific name is derived from the Latin dentatus = dentate, in reference to the form of the free termination of the sacculus. Remarks. The description of the new species is based on a single specimen collected on Mt. Fanjing, Guizhou Province, in 2001, where the two other congeners were found in 2001 and 2002. The male genitalia of the new species demonstrate that it is congeneric with S. tapaishani and S. ochriclivis, and the differences convincingly separate it from the two previously described species.Published as part of Wang, Xinpu & Li, Houhun, 2007, Review of the genus Synochoneura Obraztsov, with the description of a new species from China (Lepidoptera: Tortricidae), pp. 51-57 in Zootaxa 1547 on pages 53-54, DOI: 10.5281/zenodo.17801

Egogepa Razowski

Egogepa Razowski Egogepa Razowski, 1977: 323. Type Species. Egogepa zosta Razowski, 1977, by original designation. Diagnosis. The genus is characterized by the following characters: forewing with all veins separate, except R 4 -R 5 long stalked and chorda vestigial; hindwing with Rs-M 1 short stalked and hairbrush between anal and cubital veins; male genitalia with uncus strong, socius large and drooping, costa of valva long and well developed, sacculus simple, and coecum penis lacking; and female genitalia with sterigma cup-shaped, antrum membranous, and signum absent. Discussion. Razowski (1977) compared Egogepa with Epagoge and Gnorismoneura. He indicated that Egogepa differs from the latter two mainly in the structure of male genitalia. Razowski (1987) later pointed out that the shape of the aedeagus was an autapomorphy of Egogepa, and the genus was an offshoot of Gnorismoneura. According to Razowski (1987) and Jinbo (2000), Egogepa and Gnorismoneura belong to the primitive Archipini group. Our study supports Razowski’s view, viz. Egogepa and Gnorismoneura are closely related. They share a similar long, well developed costa of the valva; they differ by the absence of the coecum penis and signum in Egogepa. Species of Egogepa also have a special hairbrush in the hindwing, which may be another autapomorphy of the genus. Biology.
