Comparison between a phenomenological approach and a morphoelasticity approach regarding the displacement of extracellular matrix
Plastic (permanent) deformations were earlier, modeled by a phenomenological model in Peng and Vermolen (Biomech Model Mechanobiol 19(6):2525–2551, 2020). In this manusctipt, we consider a more physics-based formulation that is based on morphoelasticity. We firstly introduce the morphoelasticity approach and investigate the impact of various input variables on the output parameters by sensitivity analysis. A comparison of both model formulations shows that both models give similar computational results. Furthermore, we carry out Monte Carlo simulations of the skin contraction model containing the morphoelasticity approach. Most statistical correlations from the two models are similar, however, the impact of the collagen density on the severeness of contraction is larger for the morphoelasticity model than for the phenomenological model.Numerical Analysi
Microlejeunea strasbergii Ah-Peng & Bardat 2011
30. Microlejeunea strasbergii Ah-Peng & Bardat (2011: 669) Family:— Lejeuneaceae. Distribution:— Endemic. Habitat:— Microlejeunea strasbergii appears to be restricted to the Piton des Neiges volcano slopes, in montane and sub-alpine levels of the mesotherm forest (forest of Acacia heterophylla Willd.) and to the high ericoid formations (bushes of Philippia sp. or Sophora sp.). Ecologically, it seems that M. strasbergii is a specialist of corticolous habitats, growing over other bryophytes or directly on tree bark. Threat:— Small and restricted populations with a narrow altitudinal range (1750–2350 m), maybe sensitive to global warming. IUCN threat category:— VU[D2] Specimens:— Known from 5 localities, Commune de Saint-Benoît, GR du Piton des Neiges, epiphyllous on corticolous bryophytes, 29 March 2008, 21°05'17''S, 55°30'16''E, Ah-Peng, Bardat, Chuah-Petiot & Hedderson 1950P2Q2TC2, (holotype: REU; isotypes: PC); Takamaka trail, eastern slope of Piton des Neiges, corticolous between 0–50 cm, 21°05'51 S, 55°35'19 E, 28 March 2008, 1150 m, Ah-Peng et al. 1150P2Q3TA1; GR Piton des Neiges trail, corticolous between 0–50 cm, 21°04'42 S, 55°31'42 E, 29 March 2008, 1750 m, Ah-Peng et al. 1750P2Q3TA2; idem, corticolous between 50 cm – 1 m, Ah-Peng et al. 1750P2Q3TB2; idem corticolous between 1–2 m, 21°05'17 S, 55°30'16 E, 29.03.2008, 1950 m, Ah-Peng et al. 1950P1Q3TC3; idem corticolous between 50 cm – 1 m, 21°05'15 S, 55°31'20 E, 1950 m, Ah-Peng et al. 1950P2Q1TB3; idem corticolous between 50 cm – 1 m, 21°05'39 S, 55°30'57 E, 2150 m, Ah-Peng et al. 2150P2Q1TB3; idem corticolous between 0–50 cm, 21°05'56 S, 55°30'23 E, 2350 m, Ah-Peng et al. 2350P1Q2TA3.Published as part of Ah-Peng, Claudine, Bardat, Jacques, Pócs, Tamás, Söderström, Lars, Staménoff, Pierre & Strasberg, Dominique, 2012, Red List of liverworts and hornworts for Réunion (Mascarene archipelago), pp. 1-23 in Phytotaxa 68 (1) on page 15, DOI: 10.11646/phytotaxa.68.1.1, http://zenodo.org/record/506608

Parbatthorax proiectus Irfan & Peng 2019, sp. nov.
Parbatthorax proiectus sp. nov. urn:lsid:zoobank.org:act: 29B068AE-D2E4-4BC7-813D-197825629C3D Figs 1–7 Diagnosis The new species is closely related to Parbatthorax unicornis Tanasevitch, 2019 in having the male carapace modified with a thick horn-shaped spine and the palp with a similar embolic division (Figs 1–4; Tanasevitch 2019: figs 1–8). It can, however, be distinguished by the denticulate tibial apophyse and the highly modified paracymbium in the new species (Figs 2 A–D, 3A–B, 4A–B), whereas the tibial teeth are absent and the paracymbium is less modified in P. unicornis (Tanasevitch 2019: fig. 3). Etymology The species name comes from the Latin adjective ‘ proiectus ’ meaning ‘protruding’ and refers to the projections on the distal margin of the male palpal tibia. The gender is masculine.

KAIDAH MORFOFONEMIK PREFIKS PENG- DALAM BAHASA INDONESIA
This study aims to reveal the morphophonemic rules of peng prefixes in Indonesian. This research is a type of qualitative research using a morphophonemic approach. The data in this study are words that use the prefix {peng-} obtained from digital track records. The method used is the listening method followed by observation and note-taking techniques. In the data analysis, the distribution method was used with the Direct Element Sharing technique. The results showed that there were three morphophonemic processes: (1) phoneme changes occurred in the prefix {peng-} which was nasalized to /pem-/, /peny-/, /pen-/, and /peng-/; (2) the addition of phonemes occurs in the affix {peng-} which is nasalized to become /penge-/; and (3) the omission of phonemes occurs in the prefix {peng-} to /pe/, and basic morphemes with initial phonemes /k/, /t/, /s/, /p/.
